Description

Technical Field

[0001] The utility model relates to the technical field of equipment maintenance tools, in particular to a portable fire-fighting equipment maintenance tool. Background Art

[0002] Fire hydrants, formally known as fire hydrants, are a type of fixed fire-fighting facilities. Their main function is to control combustibles, isolate combustibles, and eliminate ignition sources. They are divided into indoor fire hydrants and outdoor fire hydrants. Indoor fire hydrants are used by indoor pipes to supply water to the fire scene. They are usually threaded at the end of the water pipes and are indoor fixed fire-fighting facilities in factories, warehouses, high-rise buildings, public buildings, and ships. The use of fire hydrants requires regular inspection and maintenance to ensure that they do not malfunction when needed.

[0003] When a fire hydrant is damaged, it needs to be disassembled with tools. The common maintenance tool is a wrench. The fire hydrant head is twisted with the wrench to remove it from the upper end of the water pipe. During the disassembly process, after the fire hydrant is rotated with the wrench, the wrench needs to be removed and re-clamped, and twisted repeatedly to achieve the removal of the fire hydrant head. In addition, since indoor fire hydrants are usually installed in fire boxes with limited space, the wrench cannot be moved to a larger angle, which greatly affects the efficiency of disassembly. Utility Model Content

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3 As shown, a portable fire-fighting equipment maintenance tool includes a disassembly collar 1, a disassembly hole 2 is provided in the center of the disassembly collar 1, and at least one clamping block 12 is provided on the inner side of the disassembly hole 2. A limiting column 14 is fixedly connected to one side of the clamping block 12, and a limiting slot cooperating with the limiting column 14 is provided on the inner wall of the disassembly hole 2. An adjustment mechanism for driving the clamping block 12 to slide is provided on the disassembly collar 1, and the adjustment mechanism includes adjustment slots 11 arranged along a ring array on the disassembly collar 1, and the adjustment slots 11 are all threadedly connected with fixing bolts 13 extending into the disassembly hole 2, and the clamping block 12 is rotatably connected to one end of the fixing bolt 13.

[0021] The outer wall of the disassembly collar 1 is rotatably sleeved with a connecting sleeve 4, and one side of the connecting sleeve 4 is fixedly connected to a handle 6. The outer wall of the disassembly collar 1 is fixedly sleeved with a gear ring 3. The inner wall of the connecting sleeve 4 is provided with an annular groove 5 that cooperates with the gear ring 3. One end of the handle 6 is provided with a slot, and an adjusting rod 7 is slidably inserted in the slot. One end of the slot is fixedly connected with a return spring 10 that cooperates with the adjusting rod 7. One end of the adjusting rod 7 is fixedly connected with a limiting block 12 that meshes with the gear ring 3. One side of the annular groove 5 is provided with a jack 15 that cooperates with the limiting tooth block 9. The outer wall of the adjusting rod 7 is fixedly connected to at least one connecting block, and the outer wall of the handle 6 is provided with a sliding hole 21 that cooperates with the connecting block. One end of the connecting block is fixedly connected with an adjusting sleeve 8 that is slidably sleeved on the outer wall of the handle 6, and one end of the handle 6 is provided with a limiting protrusion 20.

[0022] A positioning groove 16 is provided on one side of the handle 6, and a positioning block 18 is slidably inserted in the positioning groove 16. The cross-section of the positioning block 18 is a right-angled trapezoid. A positioning spring 17 cooperating with the positioning block 18 is provided in the positioning groove 16, and a positioning hole 19 cooperating with the positioning block 18 is provided on the adjusting sleeve 8.

[0023] In specific use, the fire hydrant is inserted into the disassembly hole 2, and the fixing bolt 13 is screwed. Under the limit of the limit column 14, the clamping block 12 abuts against the outer wall of the fire hydrant, and the handle 6 drives the connecting sleeve 4 and the disassembly clamp ring 1 to rotate the fire hydrant. When the handle 6 swings to the limit position and cannot swing anymore, the positioning block 18 is pressed, so that the positioning block 18 passes through the positioning hole 19 and extends into the positioning groove 16, and the positioning spring 17 is squeezed and deformed. The adjusting sleeve 8 is pulled to make the connecting block slide upward along the sliding hole 21, so that the upper end of the positioning block 18 abuts against the inner wall of the adjusting sleeve 8, and the adjusting sleeve 8 drives the adjusting rod 7 to squeeze the reset spring 10 to release. The handle 6 is swung in the opposite direction to drive the connecting sleeve 4 to rotate along the outer wall of the disassembly collar 1. After it is rotated to a suitable position, the adjusting sleeve 8 is released. Under the restoring elastic force of the reset spring 10, the adjusting rod 7 is pushed to push the limiting block 12 into the annular groove 5 again. The position of the handle 6 is fine-tuned left and right to make the limiting block 12 mesh with the gear again. At the same time, when the adjusting sleeve 8 moves to the position where the positioning hole 19 coincides with the positioning groove 16, the positioning block 18 is inserted into the positioning hole 19 again to fix the position of the adjusting sleeve 8. The handle 6 is toggled again to disassemble it along with the fire hydrant.
