本发明涉及一种液压夹紧装置，属于工程机械领域。The invention relates to a hydraulic clamping device, which belongs to the field of engineering machinery.
背景技术Background technique
重型货物的起重为工程中经常遇到的问题，起重货物之前第一步先要固定物体，当前固定物体的方法主要是如叉车的托举式，其原理为选择两个托举点使得物体在提升过程中能实现自身的平衡，或者如工厂中常见的行车这种拴绳钩挂的固定方式，将物体用绳子捆好后用行车上的钩子钩住或者直接用行车上的钩子钩住物体上的某个孔再将物体提起来。这两种起重前固定物体的方式都有其自身的局限性，如叉车的托举式，其使得物体提升过程中保持平衡完全凭叉车司机的经验，且物体底部必须有一定的空隙叉车的货叉才能进入从而托起物体，栓绳钩挂式在起重物体前需要做较长时间的准备工作，且对物体自身有一定的要求，如有没有可以用于钩挂的孔，这就使得起重物体变得困难和不便，工程中因为固定物体的不便，很多重物的搬运仍以人力为主，如园林绿化做路基的长方形石头和袋装水泥的运输的搬运等很多都是以人力来实现，其增加了货物成本且工作效率差，恶劣的工作环境和繁重的体力消耗，一直阻碍着相关行业高效快速的发展。The lifting of heavy goods is a problem often encountered in engineering. Before lifting goods, the first step is to fix the object. The current method of fixing objects is mainly the lifting method of a forklift. The principle is to select two lifting points so that The object can achieve its own balance during the lifting process, or it can be fixed with a leash hook such as the common driving car in the factory. After the object is tied up with a rope, it can be hooked with the hook on the driving car or directly hooked with the hook on the driving car. Hold a hole in the object and lift the object. These two methods of fixing objects before lifting have their own limitations, such as the lift of a forklift, which makes the balance of the object during the lifting process completely dependent on the experience of the forklift driver, and there must be a certain gap at the bottom of the object. The fork can only enter to lift the object. The tethered hook type needs a long time of preparation before lifting the object, and has certain requirements for the object itself. If there is no hole that can be used for hooking, this will It makes it difficult and inconvenient to lift objects. Because of the inconvenience of fixing objects in the project, the handling of many heavy objects is still dominated by manpower. It is realized by manpower, which increases the cost of goods and has poor work efficiency. The harsh working environment and heavy physical exertion have always hindered the efficient and rapid development of related industries.
发明内容Contents of the invention
本发明提供了一种液压夹紧装置，以解决工程中起重物体前固定物体时所遇到的困难，其通过相关机构的设计将液压的轴向力转化为与其轴向垂直的夹紧力，液压因其轴向强大的输出力在工程中得到了广泛的应用，但其与轴向垂直的受力能力很差且极易损坏其油缸，本发明通过机构的设计将液压的轴向力转化为与其轴向垂直的夹紧力用来实现在重物起重前对物体的固定，将起重一个物体简化为夹紧和提升这两个过程。The invention provides a hydraulic clamping device to solve the difficulties encountered in fixing objects in front of lifting objects in engineering, which converts the hydraulic axial force into a clamping force perpendicular to its axial direction through the design of related mechanisms , hydraulic pressure has been widely used in engineering because of its strong axial output force, but its force bearing capacity perpendicular to the axial direction is very poor and its oil cylinder is easily damaged.

Through the hole in the base of the hydraulic jack 13 and the hole III17 in the middle of the lower base 14, the hydraulic jack 13 is fixed on the lower base 14 with the threaded connection between the nut I10 and the bolt 9, and one end of the bracket 8 passes through the holes located around the lower base 14. Fix one end of the bracket 8 on the lower base 14 through the thread at the end of the bracket 8 with a nut II11 through the hole I15, and the other end of the bracket 8 passes through the hole I15 located around the upper base 7 and fix the bracket 8 through the thread at the end of the bracket 8 with the nut II11. The other end of the connecting rod 6 is fixed on the upper base 7, one end of the connecting rod 6 is connected with the hole IV18 on the boom 12 through the round key I3, and the other end of the connecting rod 6 is connected with the clamping handle I1 or the clamping handle II2 through the round key II4 The hole Ⅴ19 is connected, the clamping handle I1 and the clamping handle II2 are connected to the hole VI20 on the lower base 14 through the hole VI20 in the middle with the round key III5; there are two clamping handles I1 and II2 respectively, and four connecting rods 6 , two connecting rods 6 are connected to the clamping handle I1, and two connecting rods 6 are connected to the clamping handle II2.

所述夹柄Ⅰ1与下底座14、夹柄Ⅱ2与下底座14的连接方式均为铰链连接。The connections between the clamping handle I1 and the lower base 14, and between the clamping handle II2 and the lower base 14 are hinge connections.
本发明的工作原理是：The working principle of the present invention is:
当需要夹紧重物时液压顶13处于加压的升长状态，由于上端通过孔Ⅱ16和螺母Ⅰ10与起重臂12固定，在液压顶13升长的过程中将会将起重臂12向上推，起重臂12以铰链的形式与连杆6连接，连杆6以铰链的形式与夹柄Ⅱ2、夹柄Ⅰ1连接，夹柄Ⅱ2、夹柄Ⅰ1以铰链的形式与下底座14连接，所以当起重臂12在液压顶13的作用下向上上升时将会带着连杆6和夹柄Ⅱ2、夹柄Ⅰ1一起上升且连杆6、夹柄Ⅱ2、夹柄Ⅰ1在这个过程中连杆6与起重臂12、连杆6与夹柄Ⅰ1、连杆6与夹柄Ⅱ2、夹柄Ⅰ1与夹柄Ⅱ2相对于他们圆键连接的中心，其相对角度处于动态变化中，这样的运动效果将会使的夹柄Ⅰ1夹柄Ⅱ2末端的夹紧部位彼此靠近从而实现对重体的夹紧过程。When it is necessary to clamp heavy objects, the hydraulic jack 13 is in a pressurized and elongated state. Since the upper end is fixed to the boom 12 through the hole II16 and the nut I10, the boom 12 will be lifted upward during the elongation of the hydraulic jack 13. Push, the boom 12 is connected to the connecting rod 6 in the form of a hinge, the connecting rod 6 is connected to the clamping handle II2 and the clamping handle I1 in the form of a hinge, and the clamping handle II2 and I1 are connected to the lower base 14 in the form of a hinge, Therefore, when the boom 12 rises upward under the action of the hydraulic jack 13, it will take the connecting rod 6, the clamping handle II2, and the clamping handle I1 together to rise together, and the connecting rod 6, the clamping handle II2, and the clamping handle I1 will be connected in this process. The relative angles between rod 6 and jib 12, connecting rod 6 and clamping handle I1, connecting rod 6 and clamping handle II2, clamping handle I1 and clamping handle II2 relative to the center of their circular key connection are in dynamic change, such The movement effect will make the clamping parts at the ends of the clamping handle I1 and the clamping handle II2 approach each other so as to realize the clamping process of the counterweight.
当需要释放重物时液压顶13处于减压的缩短的状态，由于上端通过孔Ⅱ16和螺母Ⅰ10与起重臂12固定，在液压顶13缩短的过程中将会将起重臂12向下拉，起重臂12以铰链的形式与连杆6连接，连杆6以铰链的形式与夹柄Ⅱ2、夹柄Ⅰ1连接，夹柄Ⅱ2、夹柄Ⅰ1以铰链的形式与下底座14连接，所以当起重臂12在液压顶13的作用下向下下降时将会带着连杆6和夹柄Ⅱ2、夹柄Ⅰ1一起下降且连杆6、夹柄Ⅱ2、夹柄Ⅰ1在这个过程中连杆6与起重臂12、连杆6与夹柄Ⅰ1、连杆6与夹柄Ⅱ2、夹柄Ⅰ1与夹柄Ⅱ2相对于他们圆键连接的中心，其相对角度处于动态变化中，这样的运动效果将会使的夹柄Ⅰ1夹柄Ⅱ2末端的夹紧部位彼此远离从而实现对重体的释放过程。When the weight needs to be released, the hydraulic jack 13 is in a shortened state of decompression. Since the upper end is fixed to the boom 12 through the hole II16 and the nut I10, the boom 12 will be pulled down during the shortening process of the hydraulic jack 13. The boom 12 is connected to the connecting rod 6 in the form of a hinge, the connecting rod 6 is connected to the clamping handle II2 and the clamping handle I1 in the form of a hinge, and the clamping handle II2 and I1 are connected to the lower base 14 in the form of a hinge, so when When the boom 12 descends downward under the action of the hydraulic jack 13, it will bring the connecting rod 6, the clamping handle II2, and the clamping handle I1 down together, and the connecting rod 6, the clamping handle II2, and the clamping handle I1 will connect the rods during this process. 6 and boom 12, connecting rod 6 and clamping handle I1, connecting rod 6 and clamping handle II2, clamping handle I1 and clamping handle II2 relative to the center of their round key connections, their relative angles are in dynamic change, such movement The effect will be to make the clamping parts at the ends of the clamping handle I1 and the clamping handle II2 away from each other so as to realize the release process of the counterweight.
本发明的有益效果是：通过机构的设计使得液压顶巨大的轴向输出力转化为能够足以夹住重物的横向力，其通过简单的液压顶的加压和释压实现对重物的夹紧和释放，提高了运输重物的效率，减轻了人力劳动的负担。这种夹紧装置通过其上底座可以悬挂和固定的方式与很多起重机器配合使用。The beneficial effects of the present invention are: through the design of the mechanism, the huge axial output force of the hydraulic jack is converted into a lateral force sufficient to clamp the heavy object, which realizes the clamping of the heavy object through simple pressurization and release of the hydraulic jack Tight and release, which improves the efficiency of transporting heavy objects and reduces the burden of human labor. This clamping device is used in cooperation with many lifting machines by means of which the upper base can be suspended and fixed.
