Description
技术领域Technical Field
本申请涉及检测设备的技术领域，尤其是涉及一种天然气管道检测设备。The present application relates to the technical field of detection equipment, and in particular to a natural gas pipeline detection equipment.
背景技术Background Art
随着天然气行业的快速发展，天然气管道的安全运行对于保障能源供应和社会经济稳定具有重要意义。With the rapid development of the natural gas industry, the safe operation of natural gas pipelines is of great significance to ensuring energy supply and social and economic stability.
对于天然气管道的抗拉能力检测，常见的检测方式为实验室检测，天然气管道使用前于实验室内通过拉伸设备施加一定拉力进行拉伸，从而通过观察形变情况得到天然气管道的抗拉能力。The common testing method for tensile strength of natural gas pipelines is laboratory testing. Before use, the natural gas pipeline is stretched in the laboratory by applying a certain tensile force through a stretching device, so that the tensile strength of the natural gas pipeline can be obtained by observing the deformation.
但是，深埋地下的天然气管道在长期使用过程中，由于受到内外因素的影响，管壁可能出现缺陷，使得天然气管道的抗拉能力受到影响。为了确定天然气管道在实际使用情况下抗拉能力的变化，预测该使用情况下天然气管道的使用寿命，使用一定时间后，会更换一段天然气管道，然后将更换下的天然气管道运输至实验室进行抗拉检测，比较繁琐。However, during the long-term use of the natural gas pipeline buried deep underground, due to the influence of internal and external factors, defects may appear on the pipe wall, which affects the tensile strength of the natural gas pipeline. In order to determine the change in the tensile strength of the natural gas pipeline under actual use and predict the service life of the natural gas pipeline under such use, a section of the natural gas pipeline will be replaced after a certain period of use, and then the replaced natural gas pipeline will be transported to the laboratory for tensile testing, which is quite cumbersome.
发明内容Summary of the invention
为了方便对实际投入使用的天然气管道进行抗拉检测，本申请提供一种天然气管道检测设备。In order to facilitate tensile testing of natural gas pipelines that are actually put into use, the present application provides a natural gas pipeline testing device.

具体实施方式DETAILED DESCRIPTION
以下结合附图1-5对本申请作进一步详细说明。The present application is further described in detail below in conjunction with Figures 1-5.
本申请实施例公开一种天然气管道检测设备。The embodiment of the present application discloses a natural gas pipeline detection device.
实施例Example
参见图1，检测时先截断其中两段天然气管道内流通的天然气，然后拆卸取下其中一段天然气管道，之后即可对另一段天然气管道进行检测，此时拆卸取下天然管道形成的空间用于容纳检测的天然气管道产生的形变。检测设备包括环状结构的驱动套1，驱动套1套设于天然气管道外周侧，驱动套1有两个且相对设置，驱动套1内周侧壁与天然气管道外周侧壁之间相互抵接。Referring to Figure 1, during the inspection, the natural gas flowing in two sections of the natural gas pipeline is first cut off, and then one section of the natural gas pipeline is removed, and then the other section of the natural gas pipeline can be inspected. At this time, the space formed by removing the natural pipeline is used to accommodate the deformation of the natural gas pipeline to be inspected. The inspection equipment includes a drive sleeve 1 of an annular structure, which is sleeved on the outer peripheral side of the natural gas pipeline. There are two drive sleeves 1 and they are arranged oppositely, and the inner peripheral side wall of the drive sleeve 1 and the outer peripheral side wall of the natural gas pipeline are mutually abutted.
参见图1，检测设备还包括夹持套2，夹持套2套设于天然气管道外周侧，夹持套2有两个且对称设置，驱动套1位于两个夹持套2之间。夹持套2形成有滑槽211，滑槽211沿夹持套2的径向延伸，滑槽211有多个且以夹持套2中轴线为中心沿圆周方向均匀间隔设置。Referring to Fig. 1, the detection device further comprises a clamping sleeve 2, which is sleeved on the outer peripheral side of the natural gas pipeline, and there are two clamping sleeves 2 and they are symmetrically arranged, and the driving sleeve 1 is located between the two clamping sleeves 2. The clamping sleeve 2 is formed with a slide groove 211, and the slide groove 211 extends along the radial direction of the clamping sleeve 2. There are multiple slide grooves 211 and they are evenly spaced along the circumferential direction with the central axis of the clamping sleeve 2 as the center.
参见图1与图2，检测设备还包括夹持柱3，夹持柱3有多个且与滑槽211一一对应。夹持套2设置有限制块23，限制块23与夹持柱3一一对应，限制块23固定在滑槽211槽壁上。夹持柱3侧壁形成有限制槽32，限制块23滑动于限制槽32，对夹持柱3的运动方向进行引导，使得夹持柱3沿夹持套2的径向滑动于滑槽211。Referring to FIG. 1 and FIG. 2 , the detection device further includes a clamping column 3, which has a plurality of clamping columns 3 and corresponds one to one with the slide groove 211. The clamping sleeve 2 is provided with a limiting block 23, which corresponds one to one with the clamping column 3 and is fixed on the wall of the slide groove 211. A limiting groove 32 is formed on the side wall of the clamping column 3, and the limiting block 23 slides in the limiting groove 32 to guide the movement direction of the clamping column 3, so that the clamping column 3 slides in the slide groove 211 along the radial direction of the clamping sleeve 2.
参见图1与图3，夹持柱3靠近驱动套1一侧倾斜形成有驱动面31，驱动面31朝向驱动套1。驱动套1内周侧壁倾斜形成有滑动面11，初始状态时，驱动面31与滑动面11相抵接。当两个相对驱动套1分别朝两侧夹持套2滑动时，驱动套1沿轴线方向且朝相背方向拉伸天然气管道，并且拉伸过程中，滑动面11滑动于驱动面31，使得夹持柱3滑动靠近且夹持天然气管道，同时驱动套1通过夹持柱3对天然气管道施加拉伸作用力，提升驱动套1对天然气管道的拉伸效果，降低拉伸天然气管道过程中，驱动套1与天然气管道相对滑动影响拉伸结果的可能。Referring to FIG. 1 and FIG. 3 , the clamping column 3 is inclined to form a driving surface 31 on one side close to the driving sleeve 1, and the driving surface 31 faces the driving sleeve 1. The inner peripheral side wall of the driving sleeve 1 is inclined to form a sliding surface 11, and in the initial state, the driving surface 31 abuts against the sliding surface 11. When the two relative driving sleeves 1 slide toward the clamping sleeves 2 on both sides respectively, the driving sleeve 1 stretches the natural gas pipeline along the axial direction and in opposite directions, and during the stretching process, the sliding surface 11 slides on the driving surface 31, so that the clamping column 3 slides close to and clamps the natural gas pipeline. At the same time, the driving sleeve 1 applies a stretching force to the natural gas pipeline through the clamping column 3, thereby improving the stretching effect of the driving sleeve 1 on the natural gas pipeline and reducing the possibility that the relative sliding between the driving sleeve 1 and the natural gas pipeline affects the stretching result during the stretching process of the natural gas pipeline.

The power assembly includes a power hydraulic cylinder 5, a power plate 51, and a connecting column 52. The power plate 51 includes a first power plate 511 and a second power plate 512. In the embodiment of the present application, the first power plate 511 and the second power plate 512 are arranged opposite to each other and are respectively located above the corresponding drive sleeves 1; in other embodiments, the first power plate 511 and the second power plate 512 are arranged opposite to each other and are located at the installation position of the disassembled natural gas pipeline.

本申请实施例一的一种天然气管道检测设备的实施原理为：The implementation principle of a natural gas pipeline detection device in the first embodiment of the present application is:
检测前，先进行驱动套1、夹持套2、动力液压缸5的安装。检测时，启动动力液压缸5，使得驱动套1相互远离，此时驱动套1拉伸天然气管道的同时驱动夹持柱3夹持天然气管道，使得驱动套1通过夹持柱3对天然气管道施加拉伸作用力，提升驱动套1对天然气管道的拉伸效果，降低拉伸天然气管道过程中，驱动套1与天然气管道相对滑动影响拉伸结果的可能。检测完成后，受到检测的天然气管道可以拆卸取下并更换新的天然气管道。Before testing, the drive sleeve 1, the clamping sleeve 2, and the power hydraulic cylinder 5 are installed. During testing, the power hydraulic cylinder 5 is started to move the drive sleeves 1 away from each other. At this time, the drive sleeve 1 stretches the natural gas pipeline and drives the clamping column 3 to clamp the natural gas pipeline, so that the drive sleeve 1 applies a stretching force to the natural gas pipeline through the clamping column 3, thereby improving the stretching effect of the drive sleeve 1 on the natural gas pipeline and reducing the possibility that the relative sliding between the drive sleeve 1 and the natural gas pipeline affects the stretching result during the stretching process of the natural gas pipeline. After the test is completed, the tested natural gas pipeline can be disassembled and replaced with a new one.
实施例Example
参见图4，本申请实施例二与实施例一的不同之处在于夹持套2以及驱动套1的结构。Referring to FIG. 4 , the difference between the second embodiment of the present application and the first embodiment lies in the structures of the clamping sleeve 2 and the driving sleeve 1 .
参见图4，驱动套1包括驱动半环12，驱动半环12有两个对称设置，驱动半环12为半环状结构，两个驱动半环12相互配合形成环状结构。4 , the driving sleeve 1 includes a driving half ring 12 , which has two symmetrically arranged driving half rings 12 . The driving half ring 12 is a semi-ring structure, and the two driving half rings 12 cooperate with each other to form a ring structure.
参见图4，两个驱动半环12的一端相互铰接，其中一个驱动半环12滑动穿设有驱动螺栓13，驱动螺栓13螺纹连接于另一个驱动半环12。使用时两个驱动半环12抱持天然气管道，然后正转驱动螺栓13螺纹连接至另一个驱动半环12，实现两个驱动半环12固定于天然管道外周侧。为了提升两个驱动半环12抱持天然气管道的稳固程度，驱动螺栓13可以螺纹连接驱动螺母进行配合。Referring to FIG. 4 , one end of the two driving half rings 12 is hinged to each other, and a driving bolt 13 is slidably passed through one of the driving half rings 12, and the driving bolt 13 is threadedly connected to the other driving half ring 12. When in use, the two driving half rings 12 hold the natural gas pipeline, and then the driving bolt 13 is threadedly connected to the other driving half ring 12 by rotating forward, so that the two driving half rings 12 are fixed to the outer peripheral side of the natural gas pipeline. In order to improve the stability of the two driving half rings 12 in holding the natural gas pipeline, the driving bolt 13 can be threadedly connected to the driving nut for cooperation.
参见图4，夹持套2包括夹持半环21，夹持半环21有两个对称设置，夹持半环21为半环状结构，两个夹持半环21相互配合形成环状结构。4 , the clamping sleeve 2 includes a clamping half ring 21 , and the clamping half ring 21 has two symmetrical arrangements. The clamping half ring 21 is a semi-ring structure, and the two clamping half rings 21 cooperate with each other to form a ring structure.
参见图4，两个夹持半环21的一端相互铰接，其中一个夹持半环21滑动穿设有夹持螺栓22，夹持螺栓22螺纹连接于另一个夹持半环21。使用时两个夹持半环21抱持天然气管道，然后正转夹持螺栓22螺纹连接至另一个夹持半环21，实现两个夹持半环21固定于天然管道外周侧。为了提升两个夹持半环21抱持天然气管道的稳固程度，夹持螺栓22可以螺纹连接夹持螺母进行配合。Referring to FIG4 , one end of the two clamping half rings 21 is hinged to each other, and a clamping bolt 22 is slidably passed through one of the clamping half rings 21, and the clamping bolt 22 is threadedly connected to the other clamping half ring 21. When in use, the two clamping half rings 21 hold the natural gas pipeline, and then the clamping bolt 22 is threadedly connected to the other clamping half ring 21 by rotating forward, so that the two clamping half rings 21 are fixed to the outer peripheral side of the natural gas pipeline. In order to improve the stability of the two clamping half rings 21 in holding the natural gas pipeline, the clamping bolt 22 can be threadedly connected to the clamping nut for cooperation.
参见图4与图5，两个夹持半环21分别形成有铰接槽，两个铰接槽相背设置，连接柱52与夹持半环21之间铰接相连，连接柱52位于铰接槽内。连接柱52设置有连接件，连接件包括连接块523，连接块523固定连接于连接柱52外周侧且远离夹持半环21的位置。动力板51外周侧壁形成有连接槽513，夹持半环21抱持于天然气管道外周侧后，翻转连接柱52至垂直夹持套2中轴线状态时，此时连接块523卡入连接槽513内。并且连接块523卡入连接槽513内时，连接块523侧壁与连接槽513槽壁之间滑动接触且具有摩擦力，对连接柱52进行初步固定。当第一动力板511与第二动力板512相互远离时，连接槽513槽壁与连接块523相互抵接，此时动力板51通过连接块523向连接柱52传递作用力，接着连接柱52通过抵接铰接槽槽壁向驱动套1传递动力。Referring to FIG. 4 and FIG. 5 , the two clamping half rings 21 are respectively formed with hinge grooves, and the two hinge grooves are arranged opposite to each other. The connecting column 52 is hingedly connected to the clamping half ring 21, and the connecting column 52 is located in the hinge groove. The connecting column 52 is provided with a connecting member, and the connecting member includes a connecting block 523, and the connecting block 523 is fixedly connected to the outer peripheral side of the connecting column 52 and away from the clamping half ring 21. The outer peripheral side wall of the power plate 51 is formed with a connecting groove 513. After the clamping half ring 21 is held on the outer peripheral side of the natural gas pipeline, when the connecting column 52 is turned over to a state perpendicular to the central axis of the clamping sleeve 2, the connecting block 523 is inserted into the connecting groove 513. And when the connecting block 523 is inserted into the connecting groove 513, the side wall of the connecting block 523 and the groove wall of the connecting groove 513 are in sliding contact and have friction, so that the connecting column 52 is initially fixed. When the first power plate 511 and the second power plate 512 move away from each other, the wall of the connecting groove 513 and the connecting block 523 abut against each other. At this time, the power plate 51 transmits the force to the connecting column 52 through the connecting block 523, and then the connecting column 52 transmits the power to the driving sleeve 1 by abutting against the wall of the hinge groove.
