Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is mainly used for heavy objects when constructing piping as air conditioning equipment in tunnels. This invention relates to high-place cargo unloading equipment.

0002

[Conventional technology]

Construction inside the tunnel requires a limited and narrow work environment, track equipment, and the use of the track. Due to vehicle operations, multiple types of construction work overlapping, and the construction work being relatively long distances, etc. Therefore, heavy objects such as piping must be unloaded to a high place, and There are many disadvantages to suspending materials over long distances, and there is also a lack of storage space for materials. Traditionally, workers used wall-mounted ladders, which were functionally difficult to follow. Work is carried out by means such as erecting scaffolding on top of the trolleys used and working in small groups. Ta.

0003

[Problem that the idea aims to solve]

When each worker uses a ladder in the conventional method described above, long pipes are routed to the ceiling in a tunnel. When hoisting it near a well, a chain block is generally used, and workers have to lift it manually. In order to do this, the piping must be cut into short pipes, and the workability of cutting and hanging them is poor. , Also, those who assemble scaffolding on top of trolleys require a lot of time and effort to assemble. However, it is not recommended to store it when not in use, as it may cause problems such as interfering with the operation of other vehicles on the track. There were disadvantages such as not having a place to do so, and it was very inconvenient to use it in a narrow place.

0004

[Means to solve the problem]

In view of the above, the present invention has been developed for the purpose of hoisting and hoisting cargo within a tunnel. The lower end of a ladder-like loading frame with track rods on both sides, which simplifies the construction work. is pivotally supported on a board that can be mounted on a rail in the tunnel, and is mounted along the track rod of the unloading frame. A hanging wire connected to a loading platform that moves up and down is installed on the board via guide rolls. The unloading frame, loading platform, and board can be connected to a winch and assembled so that they can be separated from each other. It is made up of

[0005]

[Effect]

As shown in FIG. A ladder-like loading frame 4 is pivoted on the lower end 4b and the upper end is closed. After supporting it on the inner wall of the road and stabilizing the standing posture using support rods 9 if necessary. , it can be moved up and down with moving wheels 5b along both side track rods 4a, 4a of the unloading frame 4. A loading platform 5 is combined with a sea urchin, and a wire 6 with one end 6a connected to the loading platform 5 is connected to a ladder-like load. It is connected to the winch 2 via the upper pulley 7 of the lifting frame 4 and the pulley 8 on the lower base plate 1. The winch 2 is operated at any time by an engine 3 installed on the board. The load a that has been hoisted up and unwound and placed on the loading platform 5 is moved up and down.

[0006] If the load a is long, the load unloading device according to the present invention is Use multiple in series.

[0007] In addition, workers use another ladder to install load a that has been unloaded at a predetermined height. Is Umono.

[0008] When a vehicle runs in the tunnel A at a certain time, the base 1 in this device, the unloading The loading frame 4 and the loading platform 5 are separated and evacuated using the empty space near the rail B. The transport into and out of the tunnel before and after use can also be carried out by separating each of the above parts. Made work easier.

[0009]

【Example】

An embodiment of the device of the present invention will be described below with reference to FIGS. 1 and 2.

0010 In the figure, 1 is a board that is placed on rail B laid in tunnel A during use. , a protruding piece 1a is provided on the bottom surface of the rail B to prevent it from falling off from above the rail B, and the projecting piece 1a is attached to the rail B. A winch 2 and an engine 3 for driving the winch 2 were installed on the board 1.

[0011] 4 indicates a ladder-like loading frame with track rods 4a, 4a on both sides, and its lower end 4b. is pivoted on the board 1 and stands upright, and its upper end is supported on the inner wall of the tunnel. A branch piece 4c was provided protrudingly. The raceway rod 4a is made of steel with an L-shaped cross section, and one of the protruding edges was used as the trajectory, but the format of the trajectory is arbitrary.

0012 Reference numeral 5 denotes a loading platform that is assembled to move up and down with respect to the unloading frame 4, and has a loading platform 5a on the top. , and on the back side there are moving wheels 5b in contact with both side track rods 4a, 4a of the unloading frame 4. has been established.

[0013] 6 indicates a hanging wire with one end 6a tied to the back surface of the loading platform 5, as shown in FIG. After hooking the other end of the sea urchin to the guide pulley 7 attached to the upper end of the unloading frame 4, The above-mentioned winch 2 is installed on the base 1 through the guide pulley 8 on the base 1 along the back side. connected to.

[0014] 9 is for stabilizing the state in which the unloading frame 4 is placed on the board 1 and the upper part is supported on the wall. A support rod is shown which is used by being detachably connected to the middle horizontal rod of the unloading frame 4.

[0015] In the above device, as shown in FIG. For example, after placing the piping material a stably, start the engine 3 to drive the winch 2 and When the ears 6 are wound up, the wire 6 raises the loading platform 5 to a predetermined height as shown by the tentative lines. In this state, the worker can use another ladder to lift the piping material. Various operations such as hanging and fixing can be easily performed.

[0016] In addition, when rail B trains are operated on a regular or temporary basis, the wire 6 , separate the loading platform 5 and unloading frame 4 from the base 1, and place each member in an appropriate space. It can be stored and evacuated, and when used again, these parts can be assembled and worked. can continue.

[0017] In addition, in the case of a relatively long loading frame 4, it is divided into two or more pieces in the length direction, When in use, it is attached and unloaded to a high position, and when stored or transported, It may be separated when being carried out.

[0018]

[Effect of the idea]

According to the present invention, when hoisting a load to a high place in the narrow environment of a tunnel, It is easy to use and each operating part can be disassembled at any time, so it can be easily used inside a tunnel. If the vehicle is driven regularly, the device can be disassembled in a short period of time to use a small amount of space. It is easy to assemble the equipment when resuming work. It has the effect that it can be used extremely advantageously as a cargo unloading device within a tunnel.
