Description
Technical Field
[0001] The utility model relates to the technical field of explosion protection, in particular to an explosion-proof sealing ring disassembly tool. Background Art
[0002] Due to the complex environment in the mine and the existence of flammable and explosive gases, electrical equipment used in the mine, such as switch motors, must have explosion isolation and explosion resistance. That is, all equipment places components that may generate sparks, electric arcs and dangerous temperatures into the explosion-proof enclosure and seals it with a sealing ring, so that the explosion-proof enclosure separates the internal space of the equipment from the surrounding environment and improves the safety of underground operations.
[0003] Explosion-proof type equipment has strict requirement standards for the joint surface, bell mouth and shell. For a long time, due to the lack of special tools for disassembling the sealing ring and the non-standard operation of mechanical and electrical maintenance workers, the sealing ring has been damaged.
[0004] There are mainly two methods used by pre-installation electricians to disassemble the sealing ring: one is to use an iron rod to knock it out from the inner end of the bell mouth, but knocking it out with an iron rod will damage the sealing ring and deform the inside of the bell mouth, resulting in an uneven inner surface of the bell mouth. The second is to insert a flat or pointed metal object into the gap between the bell mouth and the sealing ring and slowly pry it out. However, when prying with a metal object, it will cause defects such as deformation and damage of the inlet end of the bell mouth, fracture of the internal thread, and rupture of the sealing ring.
[0005] Operating errors in these two disassembly methods will lead to explosion failure, greatly shortening the service life of the equipment, increasing the use and maintenance costs, and the disassembly efficiency of the above two methods is relatively low. Content of the Utility Model
[0006] In view of this, the utility model provides an explosion-proof sealing ring disassembly tool, and the main purpose is to avoid damage to the sealing ring and improve the disassembly efficiency of the sealing ring at the same time.
[0007] To achieve the above purpose, the utility model mainly provides the following technical solutions:
[0008] The utility model provides an explosion-proof sealing ring disassembly tool, which includes: a collision part and a force application part;
[0009] The collision part includes a guide rod, a first slider and a retaining ring. The retaining ring is detachably connected to one end of the guide rod, the other end of the guide rod is fixedly connected to a force receiving block, and the first slider is slidably connected to the guide rod;
[0010] The force - applying part includes a guiding cylinder and a reciprocating mechanism. The force - receiving block is slidably connected to the inner side of one end of the guiding cylinder. The reciprocating mechanism includes a reciprocating rod, a second slider, and a driving unit. The driving unit is fixedly connected to the other end of the guiding cylinder, and the output end of the driving unit is connected to one end of the reciprocating rod for driving the reciprocating rod to reciprocate axially along the guiding cylinder. The other end of the reciprocating rod is fixedly connected to the second slider. The second slider is slidably connected to the guiding rod. The second slider is arranged between the retaining ring and the first slider, and the second slider is connected to the first slider through an elastic member.
[0011] The object of the present utility model and the technical problems to be solved can be further achieved by the following technical measures.
[0012] Optionally, the driving unit includes a driving motor, a first connecting rod, and a second connecting rod. The driving motor is fixedly installed at the other end of the guiding cylinder. The output shaft of the driving motor is fixedly connected to one end of the first connecting rod. The other end of the first connecting rod is hinged to one end of the second connecting rod. The other end of the second connecting rod is hinged to one end of the reciprocating rod.
[0013] Optionally, it further includes a third slider. The third slider is slidably connected to the guiding rod. The third slider is arranged between the second slider and the first slider. The second slider is connected to the third slider through a spring, and the third slider is connected to the first slider through a traction rope.
[0014] Optionally, it further includes a guiding block. The guiding block is fixedly connected to the outer side wall of the guiding cylinder. The guiding block is provided with a guiding hole, and the reciprocating rod is slidably connected to the guiding hole.
[0015] Optionally, axial sliding grooves are respectively provided on the opposite inner side walls of the guiding cylinder. The opposite axial edges of the force - receiving block are respectively fixedly connected to axial sliders, and the axial sliders are slidably connected to the axial sliding grooves.
[0016] Optionally, it further includes a limiting ring. The limiting ring is fixedly connected to the inner edge of one end of the guiding cylinder to prevent the force - receiving block from detaching from the guiding cylinder.
[0017] Optionally, it further includes a holding handle. The holding handle is fixedly connected to the driving unit.
[0018] Optionally, it further includes a protective plate. The protective plate is fixedly connected to one side of one end of the guiding cylinder.

[0022] Start the driving unit. The driving unit drives the reciprocating rod to reciprocate axially along the guide cylinder. The reciprocating rod drives the second slider to reciprocate. The second slider drives the first slider to reciprocate through the elastic member;
[0023] When the second slider approaches the force-bearing block, it drives the first slider to impact the force-bearing block. The force-bearing block drives the guide rod and the retaining ring.

Detailed Description of the Invention
[0029] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended utility model purpose, the following combines the accompanying drawings and preferred embodiments to describe in detail the specific implementation manners, structures, features and their effects according to the present invention application. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0030] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0031] As Figure 1As shown in the figure, an explosion-proof seal ring disassembly tool provided by an embodiment of the present utility model includes: a collision part and a force application part;
[0032] The collision part includes a guide rod 1, a first slider 2 and a retaining ring 3. The retaining ring 3 is detachably connected to one end of the guide rod 1. The other end of the guide rod 1 is fixedly connected to a force receiving block 4. The first slider 2 is slidably connected to the guide rod 1;
[0033] The force application part includes a guide cylinder 5 and a reciprocating mechanism. The force receiving block 4 is slidably connected to the inner side of one end of the guide cylinder 5. The reciprocating mechanism includes a reciprocating rod 6, a second slider 7 and a driving unit. The driving unit is fixedly connected to the other end of the guide cylinder 5. The output end of the driving unit is connected to one end of the reciprocating rod 6 for driving the reciprocating rod 6 to reciprocate axially along the guide cylinder 5. The other end of the reciprocating rod 6 is fixedly connected to the second slider 7. The second slider 7 is slidably connected to the guide rod 1. The second slider 7 is arranged between the retaining ring 3 and the first slider 2. The second slider 7 is connected to the first slider 2 through an elastic member.
[0034] The working process of the explosion-proof seal ring disassembly tool is as follows:
[0035] During use, first pass the guide rod 1 through the inner hole of the explosion-proof seal ring 21, and then connect the retaining ring 3 to one end of the guide rod 1;
[0036] Start the driving unit. The driving unit drives the reciprocating rod 6 to reciprocate axially along the guide cylinder 5. The reciprocating rod 6 drives the second slider 7 to reciprocate. The second slider 7 drives the first slider 2 to reciprocate through the elastic member;
[0037] When the second slider 7 approaches the force receiving block 4, it drives the first slider 2 to impact the force receiving block 4. The force receiving block 4 drives the guide rod 1 and the retaining ring 3. The retaining ring 3 contacts the explosion-proof seal ring 21, thereby transmitting the impact force to the explosion-proof seal ring 21, so that the explosion-proof seal ring 21 moves outwards towards the bell mouth and is pulled out;
[0038] When the second slider 7 moves away from the force receiving block 4, the first slider 2 moves away from the force receiving block 4 accordingly, preparing for the next impact. At the same time, when the second slider 7 changes the moving direction, the elastic member buffers the impact force of the first slider 2 on the second slider 7.
[0039] In the technical solution of the present utility model, during the disassembly process of the above-mentioned seal ring 21, damage to the bell mouth and the explosion-proof seal ring 21 is avoided, and the disassembly efficiency is relatively high.
[0040] Specifically, the retaining ring 3 is sleeved on the guide rod 1 and fixed by a nut to prevent the retaining ring 3 from detaching from the guide rod 1.
[0041] Such as Figure 1 AndFigure 2 As shown, in the specific implementation manner, the driving unit includes a driving motor 8, a first connecting rod 9, and a second connecting rod 10. The driving motor 8 is fixedly installed at the other end of the guiding cylinder 5. The output shaft of the driving motor 8 is fixedly connected to one end of the first connecting rod 9. The other end of the first connecting rod 9 is hinged to one end of the second connecting rod 10. The other end of the second connecting rod 10 is hinged to one end of the reciprocating rod 6.
[0042] In this implementation manner, specifically, the driving motor 8 drives the first connecting rod 9 to perform circular motion, thereby driving the second connecting rod 10 to swing reciprocally, and further driving the reciprocating rod 6 to move linearly in a reciprocating manner.
[0043] In the specific implementation manner, it further includes a third slider 11. The third slider 11 is slidably connected to the guide rod 1. The third slider 11 is disposed between the second slider 7 and the first slider 2. The second slider 7 is connected to the third slider 11 through a spring 12. The third slider 11 is connected to the first slider 2 through a traction rope 13.
[0044] In this implementation manner, specifically, the spring 12 is sleeved on the guide rod 1. One end of the spring 12 is connected to the second slider 7, and the other end of the spring 12 is connected to the third slider 11. When the reciprocating rod 6 drives the second slider 7 to move to the end point in the direction approaching the force-receiving block 4, the spring 12 releases elastic potential energy. The third slider 11 can further approach the force-receiving block 4. Due to inertia, the first slider 2 can further approach the force-receiving block 4 relative to the third slider 11. In this way, even if the force-receiving block 4 is at a relatively deep position inside the guiding cylinder 5, the first slider 2 can still hit the force-receiving block 4.
[0045] Meanwhile, when the reciprocating rod 6 drives the second slider 7 and the third slider 11 to move in the opposite direction, the third slider 11 can also drive the first slider 2 to move in the opposite direction through the traction rope 13, preparing for the next impact on the force-receiving block 4.
[0046] Specifically, the elastic component is the spring 12.
[0047] In the specific implementation manner, it further includes a guiding block 14. The guiding block 14 is fixedly connected to the outer side wall of the guiding cylinder 5. The guiding block 14 is provided with a guiding hole. The reciprocating rod 6 is slidably connected to the guiding hole.
[0048] In this implementation manner, specifically, the guiding hole further restricts the linear sliding trajectory of the reciprocating rod 6, enabling the reciprocating rod 6 to move linearly in a reciprocating manner.
[0049] In the specific implementation manner, axial sliding grooves 15 are respectively provided on the opposite inner side walls of the guiding cylinder 5. Axial sliding blocks 16 are respectively fixedly connected to the opposite axial edges of the force-receiving block 4. The axial sliding blocks 16 are slidably connected to the axial sliding grooves 15.
[0050] In this embodiment, specifically, the axial slider 16 is slidably connected to the axial chute 15 to prevent the force-bearing block 4 from rotating radially within the guide cylinder 5.
[0051] In a specific embodiment, it further includes a limiting ring 17, and the limiting ring 17 is fixedly connected to the inner edge of one end of the guide cylinder 5 to prevent the force-bearing block 4 from detaching from the guide cylinder 5.
[0052] In this embodiment, specifically, the limiting ring 17 confines the force-bearing block 4 within the guide cylinder 5, enabling the guide rod 1 and the reciprocating rod 6 to always maintain a parallel state, thereby ensuring the consistency between the moving direction of the first slider 2 and the axial direction of the guide rod 1.
[0053] In a specific embodiment, it further includes a holding handle 18, and the holding handle 18 is fixedly connected to the driving unit.
[0054] In this embodiment, specifically, when the operator uses this tool, one hand holds the holding handle 18 and the other hand supports the guide cylinder 5, and then the explosion-proof sealing ring 21 can be disassembled.
[0055] In a specific embodiment, it further includes a protective plate 19, and the protective plate 19 is fixedly connected to the side of one end of the guide cylinder 5.
[0056] In this embodiment, specifically, when the operator uses this tool, one hand supports the lower side of the barrel wall of the guide cylinder 5, and the protective plate 19 can prevent the human hand from contacting the guide rod, thereby avoiding the impact force of the first slider 2 and the second slider 7 from hurting the human hand.
[0057] In a specific embodiment, an exhaust hole 20 is provided on the other side of the guide cylinder 5.
[0058] In this embodiment, an exhaust hole 20 is provided on the side wall of the other end of the guide cylinder 5. During the process of the force-bearing block 4 sliding along the guide cylinder 5, the gas inside the guide cylinder 5 can be discharged from the exhaust hole 20, and will not form a resistance to the movement of the force-bearing block 4.
[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
