There are water-yielding layers, impermeable layers, and seepage layers under various geological conditions. Therefore, when operating in coal mines, drainage pipes are often used in coal mines for drainage; and when the drainage pipes encounter bending sections, they need to be connected between the two drainage pipes through elbows, and the elbows and the drainage pipes are usually fixedly connected with locating pins. However, coal mines are generally in a relatively humid environment, which causes the water pipe locating pins to be worn and rusted due to long use time, making it difficult to disassemble the locating pins. It is difficult to disassemble them in place and requires a long working time, which not only affects work efficiency, but also damages the water pipe joints during violent disassembly, causing safety hazards.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides two technical solutions:

[0024] Figure 1-2 The first embodiment is shown: a positioning pin disassembly auxiliary device, including two positioning steels 1 welded perpendicularly to each other, one of the positioning steels is provided with a socket 2 for clamping the positioning pin head, and the other positioning steel is welded with a threaded steel 3 vertically arranged with the socket 2, and a swing hammer 4 is welded to the bottom of the threaded steel 3, and a counterweight block 5 is provided on the swing hammer 4 via a convenient disassembly mechanism.

[0025] The bayonet 2 is wide outside and narrow inside, and the inner end of the bayonet 2 is arc-shaped.

[0026] Among them, reinforcing steel ribs 6 are provided on the two positioning steels 1 .

[0027] The diameter of the threaded steel bar 3 is 2.5-3.5 cm, which is convenient for holding and has a certain strength.

[0028] By inserting the bayonet 2 on the positioning steel 1 into the positioning pin to be disassembled, and then swinging the swing hammer 4 at the end of the threaded steel 3, the swing hammer 4 after swinging continues to exert a force on the positioning pin under the action of inertia, so that the worn and rusted positioning pin can be disassembled, and the disassembly of the positioning pin is completed. There is no need for the staff to continuously expend physical strength to disassemble the positioning pin, which reduces the work intensity of the staff to a certain extent.

[0029] Figure 1-Figure 4 A second embodiment is shown, which mainly differs from the first embodiment in that the easy-to-disassemble mechanism includes a mounting block 7 provided on one side of the swing hammer 4, a positioning slot 8 is provided in the mounting block 7, a positioning block 9 inserted into the slot is provided on the counterweight block 5, and a locking mechanism is provided between the positioning block 9 and the positioning block mounting block 7 for locking the positioning block 9.

[0030] Among them, the locking mechanism includes locking blocks 10 arranged on both sides of the positioning plug 9, the positioning plug 9 is provided with a storage cavity 11 for storing the locking block 10, the storage cavity 11 is provided with an ejection spring 12 for ejecting the locking block 10, and the mounting block 7 is provided with a locking hole 13 for the locking block 10 to be inserted.

[0031] The outer end of the locking block 10 passing through the locking hole 13 is arranged in an arc shape.

[0032] The locking block 10 is made of steel.

[0033] Among them, a connecting rod 14 is hinged on the mounting block 7, and an extrusion block 15 matching the locking hole 13 is provided at the end of the connecting rod 14. It should be noted that the outer end of the locking block 10 is arranged in an arc shape, so that the locking block 10 is prevented from interfering with the counterweight block 5 when the counterweight block 5 is pulled out.

[0034] It should be noted that one end of the locking block 10 passes through the locking hole 13, so that the body of the locking block 10 is inserted into the locking hole 13, and a limit block with a diameter larger than the locking block 10 is provided in the storage cavity 11. In this way, when the swing hammer 4 swings, the locking block 10 can better lock the counterweight 5, and prevent the spring from being pulled out due to excessive shaking.

[0035] The counterweight block 5 can increase the weight of the swinging hammer 4, so that the swinging swinging hammer 4 has a greater inertia, and the force given by the inertia is greater, so that some larger and more difficult to disassemble positioning pins can be disassembled.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0037] When in use, first insert the bayonet 2 on the positioning steel 1 into the positioning pin to be disassembled, and then swing the swing hammer 4 at the end of the threaded steel 3, and the swing hammer 4 after swinging will continue to apply a force to the positioning pin under the action of inertia, so that the worn and rusted positioning pin can be disassembled, and the disassembly of the positioning pin can be completed, and the staff does not need to continuously consume physical strength to disassemble the positioning pin, which reduces the work intensity of the staff to a certain extent, and the staff disassembles the positioning pin intermittently due to physical strength and the reasons of the person himself in the process of disassembly by themselves, which takes a long time to disassemble the positioning pin to a certain extent, and because the swing hammer 4 is shaking, it will give the positioning pin a repeated and continuous force due to inertia, and the continuous force can disassemble the positioning pin, which reduces the disassembly time to a certain extent, and also prevents the damage to the water pipe joint caused by violent disassembly; wherein, in order to achieve a better disassembly effect , the weight of the swing hammer 4 can be increased by setting the counterweight block 5, so that the swinging swing hammer 4 has a larger inertia, and the force given by the inertia is larger, so that some larger and more difficult to disassemble positioning pins can be disassembled; some relatively simple disassembly and in order to prevent damage caused by excessive inertia, the connecting rod 14 hinged on the mounting block 7 is rotated to make the extrusion block 15 on the connecting rod 14 face the locking block 10 extending from the locking hole 13, and then the extrusion block 15 is pressed to allow the extrusion block 15 to receive the locking block 10 into the receiving cavity 11, and finally the counterweight block 5 is directly pulled out to complete the disassembly of the counterweight block 5, and during installation, the locking block 10 is first pressed, and then the positioning plug 9 is inserted into the positioning slot 8, and then under the action of the ejection spring 12, the locking block 10 can be ejected out of the receiving cavity 11 and pushed into the locking hole 13, and then the installation of the counterweight block 5 is completed, and the installation and disassembly of the counterweight block 5 improves the practicality of the entire device to a certain extent.
