Description

Technical Field

[0001] The utility model relates to a cable plug removal tool and belongs to the field of cable plugging and pulling parts. Background Art

[0002] Due to the rapid development of railways in the past two decades or so, railway power supply equipment has undergone great changes compared with the past. The overhead wires that were once mostly used for "underground lines, indoor equipment, and full-process monitoring" have now been gradually replaced by cables. Due to the upgrading of equipment, the corresponding special tools have not been developed and manufactured, equipped and used, such as the European-style cable plugs. After several years of operation, the silicone grease has evaporated, and it is quite difficult to remove the plugs during maintenance and troubleshooting. Summary of the invention

[0003] According to the problem described in the background, the problem to be solved by the utility model is: to provide a cable plug removal tool, which adopts the principle of a jack and uses a screw rod to add force to achieve a four-pound effect. The front support arm uses two iron half-moon rings to allow the half-moon rings to be in close contact with the plug opening, and the force is applied evenly. The top head uses a copper cap to contact the stainless steel stud bolt without damaging the stud bolt thread, and finally the cable plug is removed.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable plug removal tool is provided, including a screw, a hexagonal screw head, a top head, a cross bar, a cross bar hole, a support arm, a meniscus, a boss and a mounting hole. A hexagonal screw head is provided at one end of the screw, which can be rotated in conjunction with a tool. A top head is provided at the other end of the screw to support the stud bolt. A cross bar hole is provided in the middle of the cross bar. The screw passes through the cross bar hole and is installed in conjunction with the cross bar. A meniscus is installed at one end of the support arm. A mounting hole is provided at the end of the support arm away from the meniscus. The support arm passes through the cross bar through the mounting hole and is installed in conjunction with the cross bar. A boss is provided in the middle of the support arm.

[0005] Preferably, the hexagonal screw head also includes a through hole and a hexagonal wrench hole. The through hole is opened on any surface of the hexagonal screw head and passes through the entire hexagonal screw head. The hexagonal wrench hole is opened on the end face of the hexagonal screw head that is not connected to the screw. In this way, a variety of tools such as a fork wrench, a hexagonal wrench or a wire iron rod can be used to rotate the screw.

[0006] Preferably, the plug also includes a plug hole, which is opened on the end face of the plug that is not connected to the screw rod. The plug hole has a depth of 2-6 mm and a diameter greater than that of the stud bolt, thereby wrapping the stud bolt for protection.

[0007] Preferably, the meniscus is an edged style with a thin inner side and a thick outer side, so that it is easier to insert into the gap between the cable plug and the socket.

[0008] Preferably, the style of the boss is the same as the style of the outer wall of the cable plug, which makes it easier to fix the cable plug.

[0009] Preferably, the thread on the cross bar hole matches with the screw thread.

[0010] Working principle: Fix the meniscus at the front end of the two support arms to the end of the plug-in head, and fix the top head on the stud bolt. Use your hands or tools such as an adjustable fork wrench, an Allen wrench, and an iron wire rod to turn the hexagonal screw head to rotate the screw. Because the stud bolt supported by the screw is fixed on the threaded mounting rod, the screw will only rotate by itself and will not move forward and backward, so the support arm will move backward with the horizontal bar. Hold the support arm and the cable unplug with one hand, and rotate the screw with the other hand to pull the plug-in head out of the socket. Only one person is needed to complete it.

[0011] The beneficial effects of the utility model are:

[0012] 1. The through hole on the hexagonal screw head and the hexagonal wrench hole on the screw allow the screw to be rotated using tools such as a fork wrench, a hexagonal wrench or a wire, which greatly saves manpower and makes rotation more convenient.

[0013] 2. The existence of the top hole protects the thread of the stud bolt when the screw is against the stud bolt, without damaging the thread. At the same time, it can also correct the direction and prevent deviation.

[0014] 3. The cutting edge of the meniscus can better fix it in the gap between the cable plug and the socket, avoiding the problem of being unable to use tools due to the inability to enter the gap, and at the same time, the force will be evenly applied.

[0015] 4. The boss is matched with the concave part of the outer wall of the cable plug, so that it fits well and will not slide, making it more convenient to use.

[0016] 5. The force rod adopts the principle of jack setting and uses a screw to add force. Rotate the screw. Because the screw supports the stud bolt and will not move, it drives the support arm to move backward, thereby driving the cable plug to be removed. One person can complete the operation. It is simple to operate, small in size, and detachable, easy to carry, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] The following further describes the embodiments of the present utility model in conjunction with the accompanying drawings:

[0022] Embodiment 1

[0023] As Figures 1 - 3 shown, the present utility model includes a screw 1, a hexagonal screw head 2, a top head 4, a cross bar 6, a cross bar hole 7, a support arm 8, a meniscus 9, a boss 10 and a mounting hole 11. One end of the screw 1 is provided with a hexagonal screw head 2, which can be rotated by cooperating with a tool. The other end of the screw 1 is provided with a top head 4, which abuts against the stud bolt 16. A cross bar hole 7 is opened in the middle of the cross bar 6. The screw 1 passes through the cross bar hole 7 and is installed in cooperation with the cross bar 6. One end of the support arm 8 is installed with a meniscus 9. The end of the support arm 8 away from the meniscus 9 is provided with a mounting hole 11. The support arm 8 passes through the cross bar 6 through the mounting hole 11 and is installed in cooperation with the cross bar 6. A boss 10 is provided in the middle part of the support arm 8.

[0024] The hexagonal screw head 2 further includes a through hole 3 and a hexagonal wrench hole 12. The through hole 3 is opened on any surface of the hexagonal screw head 2 and penetrates the entire hexagonal screw head 2. The hexagonal wrench hole 12 is opened on the end face of the hexagonal screw head 2 at the end not connected to the screw 1. In this way, various tools such as a fork wrench, a hexagonal wrench or an iron wire rod can be used to rotate the screw 1.

[0025] The top head 4 further includes a top head hole 5. The top head hole 5 is opened on the end face of the top head 4 at the end not connected to the screw 1. The depth of the top head hole 5 is 4 mm. The diameter of the top head hole 5 is larger than the diameter of the stud bolt 16, wrapping the stud bolt 16 to play a protective role.

[0026] The meniscus 9 is in the form of a sharpened edge with a thin inner side and a thick outer side, which is easier to insert into the gap between the cable unplug 14 and the socket 15.

[0027] The boss 10 has the same outer wall style as the cable unplug 14, which is easier to fix the cable unplug 14.

[0028] The thread on the cross bar hole 7 is in threaded fit with the screw 1.

[0029] Fix the meniscus 9 at the front ends of the two support arms 8 to the end of the plug and socket head. Fix the top head 4 to the double-headed bolt 16. Use your hand or cooperate with tools such as an adjustable wrench, an Allen wrench, and an iron wire rod to rotate the hexagonal screw head 2 to make the screw 1 rotate. Since the double-headed bolt 16 against which the screw 1 presses is fixed to the threaded mounting rod 13, the screw will only rotate by itself and will not move forward or backward. Therefore, the support arm 8 will move backward along with the cross bar 6. Hold the support arm 8 and the cable plug 14 tightly with one hand, and rotate the screw 1 with the other hand to pull out the cable plug 14 from the socket 15. Only one person is needed to complete this operation.
