Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a corrosion-resistant garbage crane cable head structure which is convenient to replace. Background Art

[0002] There is usually a large amount of garbage piled up in the waste incineration plant. For this garbage, the waste incineration plant usually uses a garbage crane to grab the piled up garbage and transfer it to the next process for processing. Usually, when the garbage crane is in use, it is usually connected to an external power supply through a cable.

[0003] During the use of existing cables, if the cable is pulled externally when the garbage crane is moving, the wire core inside the cable is easily broken. Since it is broken internally, the breaking position cannot be well determined, and the cable maintenance is more troublesome at this time. For this reason, we propose a corrosion-resistant garbage crane cable head structure that is easy to replace. Utility Model Content

[0004] In view of the above problems, the utility model provides a corrosion-resistant garbage crane cable head structure that is easy to replace and can solve the problems existing in the above background technology.

[0005] The technical solution of the utility model is:

[0006] A corrosion-resistant garbage crane cable head structure that is easy to replace, includes a cable body, a first shell is movably connected to the outer side of one end surface of the cable body, a second shell is movably connected to one side of the first shell, fixed limit blocks are symmetrically provided on the outer sides of both ends of the first shell and the second shell, a movable sleeve block is movably connected to the inner side of the fixed limit block, and connecting protrusions are provided at both ends of the movable sleeve block, and fastening bolts are movably connected to the inside of the connecting protrusions, and connecting terminals are movably clamped at one end of the inner side of the first shell and the second shell.

[0011] In a further technical solution, the inner side of the fixed limiting block and the outer side of the movable sleeve block fit each other.

[0012] In a further technical solution, a side of the movable mounting ring away from the buffer spring is in contact with a side of the inner side of the first shell and the second shell away from the connecting terminal.

[0013] The beneficial effects of the utility model are:

[0014] 1. The first shell and the second shell can be connected and fixed by the connection between the movable sleeve, the connecting protrusion and the fastening bolt. Conversely, the first shell and the second shell can be quickly disassembled. When pulled, the connecting terminal on the inner side of one end of the first shell and the second shell and the plug-in connection between the outside can be automatically disconnected to avoid damage to the cable body, and the first shell, the second shell and the connecting terminal can be disassembled and replaced conveniently.

[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0022] Example:

[0023] like Figure 1-Figure 3 As shown, a corrosion-resistant garbage crane cable head structure which is easy to replace includes a cable body 1, a first shell 2 is movably connected to the outer side of one end surface of the cable body 1, a second shell 3 is movably connected to one side of the first shell 2, fixed limit blocks 4 are symmetrically provided on the outer sides of both ends of the first shell 2 and the second shell 3, a movable sleeve block 5 is movably connected to the inner side of the fixed limit block 4, and connecting protrusions 6 are provided at both ends of the movable sleeve block 5, and fastening bolts 7 are movably connected to the inside of the connecting protrusions 6, and connecting terminals 8 are movably clamped at one end of the inner side of the first shell 2 and the second shell 3.

[0024] The working principle of the above technical solution is as follows:

[0025] During use, when the entire assembly needs to be disassembled, the fastening bolt 7 is rotated and disassembled so that the fastening bolt 7 can be pulled out from the inside of the connecting protrusion 6, and the connecting protrusions 6 are no longer connected and fixed. Then the movable sleeve block 5 and the connecting protrusion 6 are moved so that the movable sleeve block 5 can be detached from the inner side of the fixed limit block 4, so that the first shell 2 and the second shell 3 can be quickly disassembled, and the operation is convenient.

[0026] In another embodiment, if Figure 3 As shown, a movable mounting ring 9 is movably sleeved on the surface of the cable body 1, a buffer spring 10 is fixedly connected to one side of the movable mounting ring 9, and a fixed mounting ring 11 is fixedly connected to the other end of the buffer spring 10, and the interior of the fixed mounting ring 11 is fixedly connected to the outer surface of the cable body 1.

[0027] When the cable body 1 is pulled, the cable body 1 can drive the fixed mounting ring 11 to move, and at the same time the cable body 1 can move inside the first shell 2, the second shell 3 and the movable mounting ring 9, so that the buffer spring 10 can be compressed inside the movable mounting ring 9 and the fixed mounting ring 11, thereby buffering the external pulling force and providing protection for the cable body 1.

[0028] In another embodiment, if Figure 3 As shown, the inner sides of the first housing 2 and the second housing 3 are provided with limiting protrusions 12 , and the outer sides of the connecting terminals 8 are provided with fixing slots 13 .

[0029] To facilitate mutual assembly between the first shell 2 and the second shell 3, the connection between the first shell 2, the second shell 3 and the connecting terminal 8 can be restricted by the mutual cooperation between the limiting protrusion 12 and the fixing slot 13, so that the connecting terminal 8 is stably located on the inner side of the first shell 2 and the second shell 3 for connection and use.

[0030] In another embodiment, if Figure 3 As shown, the outer surface of the limiting protrusion 12 is engaged with the inner surface of the fixing slot 13 .

[0031] The limiting protrusion 12 and the fixing groove 13 are engaged with each other, so that the connecting terminal 8 can be stably located inside the first housing 2 and the second housing 3 for use.

[0032] In another embodiment, if Figure 3 As shown, a guiding inclined surface 14 is provided at one end of the connecting terminal 8 close to the cable body 1 .

[0033] When the cable body 1 is reset by the buffer spring 10 and the fixing ring 11 is convenient for fixing, the inner core of the cable body 1 can fit with the inner middle part of the connecting terminal 8 under the action of the guiding slope 14, thereby ensuring stable contact.

[0034] In another embodiment, if Figure 1 As shown, the inner side of the fixed limiting block 4 and the outer side of the movable sleeve block 5 fit together.

[0035] The movable sleeve block 5 can be stably located inside the fixed limiting block 4 for use, thereby limiting the connection between the first shell 2 and the second shell 3 .

[0036] In another embodiment, if Figure 3 As shown, the side of the movable mounting ring 9 away from the buffer spring 10 is in contact with the side of the inner side of the first housing 2 and the second housing 3 away from the connecting terminal 8 .

[0037] When the cable body 1 moves, it drives the fixed installation ring 11 to move, and at this time it can ensure that the movable installation ring 9 does not move, so that the buffer spring 10 can be compressed between the fixed installation ring 11 and the movable installation ring 9, which is easy to operate.

[0038] The working principle of the utility model is as follows: during use, if the cable body 1 is subjected to external pulling force, it can drive the fixed mounting ring 11 to move, so that the buffer spring 10 can shrink between the fixed mounting ring 11 and the movable mounting ring 9, so as to buffer the external force, thereby protecting the cable body 1. After the external force disappears, the fixed mounting ring 11 can drive the cable body 1 to reset under the action of the buffer spring 10, so that the internal wire core of the cable body 1 can be inserted into the inner side of the connecting terminal 8 under the guidance of the guide bevel 14, and can be stably connected with the connecting terminal 8 to conduct the signal. When it is necessary to disassemble the whole, the fastening bolt 7 is rotated so that the fastening bolt 7 can be pulled out from the inside of the connecting protrusion 6, and then the movable sleeve block 5 drives the connecting protrusion 6 to detach from the inner side of the fixed limit block 4. At this time, the first shell 2, the second shell 3 and the connecting terminal 8 can be quickly disassembled and replaced. The overall structure is simple and easy and quick to use.

[0039] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
