Description

Technical Field

[0001] This invention relates to the field of coal mine equipment disassembly and assembly technology, and in particular to a convenient coal mine equipment disassembly and assembly device. Background Technology

[0002] Coal mining equipment utilizes various connection methods and fasteners in its structural composition. Bolt and nut connections are a common type of fastener, their detachable nature meeting the needs of disassembling and assembling various components or parts. Among various bolts and nuts, hexagonal bolts (including internal and external hexagonal bolts) and external hexagonal nuts are the most common. Based on different standards, they can be divided into metric and non-metric standards. The former standardizes the size and structure of bolts and nuts according to relevant standard models, while the latter is designed to meet specific needs, with custom-defined dimensions and structures. Metric bolts can be disassembled and assembled using a corresponding metric wrench, while non-metric bolts often require a special wrench or a linearly adjustable wrench. Existing wrenches have the following shortcomings: First, to accommodate various sizes of hexagonal bolts or nuts, manual socket replacement is usually required when using interchangeable sockets for matching and insertion. This is not only time-consuming and labor-intensive, but also prone to loss and confusion due to the multiple sockets involved, making operation inconvenient. Second, the linear adjustment wrench and the socket-changing wrench are not integrated, requiring selection based on specific needs when matching metric or non-standard bolts or nuts, thus increasing their size and making them inconvenient to carry and use. Third, traditional wrenches typically lack dedicated lighting and cleaning mechanisms, making them unsuitable for the poor lighting and dusty environments of coal mines, resulting in inconvenience and reduced work efficiency. Fourth, traditional linear adjustment wrenches cannot actively rotate while clamping the target bolt or nut, further reducing work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a convenient coal mine equipment disassembly and assembly device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A convenient coal mining equipment disassembly and assembly device includes a wrench, a clamping mechanism, an electric lifting mechanism, a hexagonal socket, a controller, and a battery. The wrench is equipped with a clamping mechanism, which includes an electric lifting mechanism and a hexagonal socket. Multiple hexagonal sockets of different sizes are slidably connected to each other vertically. The electric lifting mechanism is used to control the controllable vertical movement of any hexagonal socket. The electric lifting mechanism is electrically connected to the controller, and the controller is electrically connected to the battery.

[0006] Based on the above technical solution, the clamping mechanism includes a support base, which is slidably connected vertically to the outermost hexagonal sleeve. The electric lifting mechanism includes an electric adjustment mechanism, a transmission cylinder, a right servo motor, a moving base, a swing arm, and an electromagnet.

An electromagnet is fixed to the bottom of the support base, and a right servo motor with braking function is fixed to the right side. The transmission cylinder is located directly above each hexagonal sleeve, and moving bases are slidably connected to both the left and right sides.

The two first swing arms are symmetrically arranged and correspond to the left and right of the two support arms. A first tension spring is fixed between the first swing arm and the support arm.

The two second swing arms are arranged symmetrically to each other. The adjacent ends of the ends of the two second swing arms away from the movable seats are jointly fixed with a second tension spring.

[0011] Based on the above technical solution, the support base also includes a socket, an end cap, and a plug rod. The support base has a socket fixed at both the front and rear. The socket is made of a material that can be magnetically attracted. The end cap is covered on the top of the socket. The end cap is made of a transparent material. The plug rod made of a permanent magnet is fixed at both the front and rear. The two plug rods are detachably inserted into the two sockets. The clamp is always located below the end cap.

[0012] Based on the above technical solution, the wrench is rotatably connected to the support base, the stator of the first conductive slip ring is fixed to the support base, the stator of the first conductive slip ring is electrically connected to the left servo motor and the right servo motor, the rotor of the first conductive slip ring is fixed to the wrench, the rotor of the first conductive slip ring is electrically connected to the controller, the controller is fixed to the wrench, the virtual rotation axis of the rotor of the first conductive slip ring is coaxial with the virtual rotation axis of the wrench, the virtual rotation axis of the wrench and the support base is set along the left and right horizontal direction, a set of left and right direction spring pins are installed at the front and rear parts of the support base, the inner wall of the wrench has a limiting hole corresponding to the spring pin, when the wrench swings relative to the support base to the forward horizontal position, the limiting hole can be inserted with the spring pin at the front of the support base, when the wrench swings relative to the support base to the rear horizontal position, the limiting hole can be inserted with the spring pin at the rear of the support base, when the wrench swings relative to the support base, it can squeeze the spring pin to retract into the support base and move relative to the spring pin.

[0013] Based on the above technical solution, the wrench is arranged horizontally front to back, the clamping mechanism is located at the rear of the wrench, a protective cylinder that runs through the front of the wrench is fixed at the front of the wrench, a protective net is installed at the front end of the protective cylinder, the outer wall of the protective cylinder is provided with an anti-slip structure that can prevent slipping when gripped, a fan is installed at the front of the wrench, the turbine fan of the fan is inserted into the protective cylinder, the fan is electrically connected to the controller, the controller is equipped with and electrically connected to multiple control buttons, the control buttons are installed with the wrench, and the battery is a rechargeable battery and is installed inside the wrench.

[0014] Based on the above technical solution, the wrench includes a front rod and a rear rod, with the front rod in front and the rear rod behind. A second conductive slip ring is installed between the front rod and the rear rod. The stator of the second conductive slip ring is fixed to the front rod, and the rotor is fixed to the rear rod. The front rod and the rear rod are coaxially connected by the second conductive slip ring. A geared motor with braking function is fixed to the front rod.

[0015] Compared with the prior art, the present invention has the following advantages: When using the present invention, the corresponding hexagonal sleeve is moved downward by the electric lifting mechanism and protrudes from other hexagonal sleeves. The hexagonal sleeve can then be matched and inserted with the corresponding hexagonal bolts and hexagonal nuts. Then, by turning the wrench, the bolts and nuts can be disassembled and assembled without the need for manual replacement and disassembly of the hexagonal sleeve. The operation is convenient and easy to carry.

[0016] When adjusting the relative position of the two moving seats, the two jaws move accordingly, thereby enabling linear adjustment of the distance between them. Then, the jaws are used to clamp non-standard bolts or nuts, and the wrench can be turned to disassemble or assemble them. This combines the functions of a traditional socket wrench and a linear adjustment wrench, forming an integrated structure that reduces space occupation and makes it easy to carry and use.

[0017] The hand-held wrench, combined with a blower, can be used to clean the target area, thus achieving a dust removal effect. By holding the protective sleeve and controlling the geared motor to rotate it forward and backward, the rear rod can actively drive the clamping mechanism to rotate forward and backward, thereby quickly rotating the target bolts and nuts. The No. 1, No. 2, and No. 3 lights can be used to illuminate the area to be cleaned and the area where bolts or nuts are being installed or removed, facilitating the work and improving work efficiency.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-6 As shown, a convenient coal mine equipment disassembly and assembly device includes a wrench 1, a clamping mechanism 2, an electric lifting mechanism 3, a hexagonal socket 4, a controller 5, and a battery 6. The wrench 1 is equipped with the clamping mechanism 2, which includes the electric lifting mechanism 3 and the hexagonal socket 4. Multiple hexagonal sockets 4 of different sizes are slidably connected to each other. The electric lifting mechanism 3 is used to control the controllable up and down movement of any hexagonal socket 4. The electric lifting mechanism 3 is electrically connected to the controller 5, and the controller 5 is electrically connected to the battery 6.

[0027] In use, the electric lifting mechanism 3 controls the corresponding hexagonal socket 4 to move downwards and protrude from other hexagonal sockets 4. The hexagonal socket 4 can then be matched and inserted with the corresponding hexagonal bolts and hexagonal nuts. Then, by turning the wrench 1, the bolts and nuts can be disassembled and assembled without the need for manual replacement and disassembly of the hexagonal socket 4. It is easy to operate and portable.

[0028] The clamping mechanism 2 includes a support base 7, which is slidably connected vertically to the outermost hexagonal sleeve 4. The electric lifting mechanism 3 includes an electric adjusting mechanism 8, a transmission cylinder 9, a right servo motor 10, a moving base 11, a swing arm 12, and an electromagnet 13. The support base 7 is rotatably connected to the transmission cylinder 9. An electromagnet 13 is fixed to the bottom of the support base 7, and a right servo motor 10 with braking function is fixed to the right side. The transmission cylinder 9 is located directly above each hexagonal sleeve 4, and two moving bases 11 are slidably connected to its left and right sides. The rotating shaft of the right servo motor 10 is connected to the transmission cylinder 9 to achieve synchronous rotation. Swing arms 12 are radially fixed to the two moving bases 11 respectively. The electric adjusting mechanism 8, the right servo motor 10 ... Servo motor 10 and electromagnet 13 are electrically connected to controller 5. When the right servo motor 10 rotates, it can drive the moving seat 11 to rotate, thereby realizing the swing arm 12 swinging back and forth. When the swing arm 12 swings down to a certain angle, it can press the corresponding hexagonal sleeve 4, causing the hexagonal sleeve 4 to extend downward. The hexagonal sleeve 4 is made of a non-magnetic material that can be magnetically attracted, such as iron. The electromagnet 13 can magnetically attract each hexagonal sleeve 4 to achieve a limit until the hexagonal sleeve 4 is pressed down and moved by the swing arm 12. The electric adjustment mechanism 8 is installed with the two moving seats 11 and can adjust the left and right positions of the moving seats 11 without restricting their circumferential angle during operation.

[0029] The electric adjustment mechanism 8 includes a bidirectional lead screw 14 and a left servo motor 15. The support base 7 is rotatably connected to the bidirectional lead screw 14. The bidirectional lead screw 14 is coaxially arranged with the transmission cylinder 9. The left part of the support base 7 is fixed with a left servo motor 15 that has a braking function. The rotating shaft of the left servo motor 15 is connected to the bidirectional lead screw 14 to achieve synchronous rotation. The external threads of the left and right parts of the bidirectional lead screw 14 are symmetrical, and the left and right parts are symmetrically connected to the two moving seats 11 through threads. The transmission cylinder 9 is located outside the bidirectional lead screw 14. The left servo motor 15 is electrically connected to the controller 5. When the left servo motor 15 rotates forward and backward, it can drive the two support seats 7 to move closer and further away from each other along the transmission cylinder 9. When the right servo motor 10 and the left servo motor 15 rotate synchronously, they can drive the two support seats 7 to rotate, thereby realizing the swing of the swing arm 12.

[0030] Furthermore, depending on the size of the bolts and nuts to be disassembled and assembled, when a corresponding hexagonal socket 4 needs to be selected, the swing arm 12 is not pressing the hexagonal socket 4 and the bottom of the hexagonal socket 4 is facing downwards. Then, the power supply to the electromagnet 13 is stopped, at which point the electromagnet 13 is not magnetic. Then, the wrench 1 is held and rotated so that the bottom of each hexagonal socket 4 is facing upwards. Under the action of gravity, the hexagonal socket 4 falls and retracts into the support base 7. Then, the left servo motor 15 is controlled to rotate accordingly, while the right servo motor 10 remains braked, thereby causing the swing arm 12 to move to... Below the corresponding hexagonal sleeve 4, control the left servo motor 15 and the right servo motor 10 to rotate synchronously. The upward swing of the swing arm 12 can press the left and right parts of the hexagonal sleeve 4 upward and make it protrude upward. Then, energize the electromagnet 13, and the electromagnet 13 can magnetically attract each hexagonal sleeve 4, so that they are mutually limited (magnetism can be conducted between each hexagonal sleeve 4, thereby directly or indirectly achieving the magnetic attraction effect). At this time, the protruding hexagonal sleeve 4 can be used to cooperate and plug in with the corresponding bolt or nut.

[0031] The front ends of the left and right parts of the transmission cylinder 9 are each radially fixed with a support arm 16. The two support arms 16 are symmetrically arranged. The swing arm 12 includes a first swing arm 17. The front ends of the two moving seats 11 are each radially fixed with a first swing arm 17. The two first swing arms 17 are symmetrically arranged and correspond to the left and right of the two support arms 16. A first tension spring 18 is fixed between the first swing arm 17 and the support arm 16. The first tension spring 18 is located at the adjacent ends of the first swing arm 17 and the support arm 16 away from the radial ends of the bidirectional lead screw 14.

[0032] Furthermore, when adjusting the relative positions of the two movable seats 11, the two tension springs 18 will also extend and retract accordingly. As the transmission cylinder 9 rotates, the support arm 16, the swing arm 17, and the tension spring 18 will also move accordingly, thereby pressing and protruding the target hexagonal sleeve 4 and all the surrounding hexagonal sleeves 4 together. At this time, the hexagonal hole of the target hexagonal sleeve 4 can be inserted into the corresponding hexagonal bolt or hexagonal nut. Since multiple hexagonal sleeves 4 surround the corresponding hexagonal bolt or hexagonal nut, they can indirectly provide auxiliary support for the target hexagonal sleeve 4, reducing the possibility of deformation and clamping failure, thus improving the reliability of operation.

[0033] The top ends of the two movable seats 11 are respectively radially fixed with grippers 19, the adjacent ends and opposite ends of the two grippers 19 are parallel to each other, the support seat 7 passes through upward, and the grippers 19 protrude from the upper part of the support seat 7.

[0034] Furthermore, when adjusting the relative position of the two movable seats 11, the two jaws 19 move accordingly, thereby enabling linear adjustment of the distance between them. Then, the jaws 19 are used to clamp non-standard bolts or nuts, and the wrench 1 can be rotated to disassemble and assemble them. This combines the functions of a traditional socket wrench 1 and a linear adjustment wrench 1, forming an integrated structure that reduces space occupation and makes it easy to carry and use.

[0035] The swing arm 12 also includes a second swing arm 20. The rear ends of the two movable seats 11 are respectively radially fixed with the second swing arm 20. The two second swing arms 20 are arranged symmetrically to each other. The adjacent ends of the two second swing arms 20 away from the movable seats 11 are jointly fixed with a second tension spring 21.

[0036] Furthermore, when adjusting the relative positions of the two movable seats 11, the second tension spring 21 will also extend and retract accordingly. As the transmission cylinder 9 rotates, the second swing arm 20 will also swing accordingly, thereby pressing the target hexagonal sleeve 4, i.e., each of the hexagonal sleeves 4 in its inner circumference, together until they protrude. At this time, the hexagonal hole of the target hexagonal sleeve 4 can be inserted into the corresponding internal hexagonal hole. Since multiple hexagonal sleeves 4 in the inner circumference are inserted into the corresponding internal hexagonal hole, they can indirectly provide auxiliary support for the target internal hexagonal bolt, reducing the possibility of deformation and clamping failure, thus improving the reliability of operation.

[0037] The support base 7 also includes a socket 22, an end cap 23, and a plug rod 24. The support base 7 has a socket 22 fixed at both the front and rear. The socket 22 is made of a material that can be magnetically attracted. The end cap 23 is covered on the upper part of the socket 22. The end cap 23 is made of a transparent material, and a plug rod 24 made of a permanent magnet is fixed at both the front and rear. The two plug rods 24 are detachably inserted into the two sockets 22. The clamp 19 is always located below the end cap 23.

[0038] Furthermore, when the clamp 19 is not used to clamp non-standard bolts and nuts, the insertion rod 24 and the socket 22 are kept in contact and magnetically engaged, thereby keeping the end cap 23 closed over the support base 7. This reduces the entry of dust and foreign objects into the support base 7 and prevents interference with the transmission, thus improving working stability. When the clamp 19 is needed, the end cap 23 can be removed.

[0039] The wrench 1 is rotatably connected to the support base 7. The stator of the first conductive slip ring 34 is fixed to the support base 7. The stator of the first conductive slip ring 34 is electrically connected to the left servo motor 15 and the right servo motor 10. The rotor of the first conductive slip ring 34 is fixed to the wrench 1. The rotor of the first conductive slip ring 34 is electrically connected to the controller 5. The controller 5 is fixed to the wrench 1. The virtual rotation axis of the rotor of the first conductive slip ring 34 is coaxial with the virtual rotation axis of the wrench 1. The virtual rotation axes of the wrench 1 and the support base 7 are horizontally aligned. The support base 7 is equipped with a set of left-right oriented spring pins 25 at both the front and rear. The inner wall of the wrench 1 has a limiting hole 26 corresponding to the spring pin 25. When the wrench 1 swings relative to the support base 7 to a forward horizontal position, the limiting hole 26 can be inserted into the spring pin 25 at the front of the support base 7. When the wrench 1 swings relative to the support base 7 to a backward horizontal position, the limiting hole 26 can be inserted into the spring pin 25 at the rear of the support base 7. When the wrench 1 swings relative to the support base 7, it can squeeze the spring pin 25 to retract into the support base 7 and move relative to the spring pin 25.

[0040] Furthermore, by utilizing the cooperation between the spring pin 25 and the limiting hole 26, the wrench 1 can achieve a certain limiting effect when it is horizontally forward or backward relative to the support seat 7, making it more convenient to rotate the wrench 1 relative to the target bolt or nut.

[0041] The wrench 1 is arranged horizontally front to back. The clamping mechanism 2 is located at the rear of the wrench 1. A protective cylinder 27 that runs through the front of the wrench 1 is fixed at the front. A protective net 28 is installed at the front end of the protective cylinder 27. The outer wall of the protective cylinder 27 is provided with an anti-slip structure 37 that provides an anti-slip effect when gripped. The anti-slip structure 37 is a known prior art, such as knurling, anti-slip rubber strips, anti-slip grooves, etc. A fan 29 is installed at the front of the wrench 1. The turbine fan of the fan 29 is inserted into the protective cylinder 27. The fan 29 is electrically connected to the controller 5. The controller 5 is equipped with and electrically connected to multiple control buttons 30. The control buttons 30 are installed with the wrench 1. The battery 6 is a storage battery 6 and is installed inside the wrench 1.

[0042] Furthermore, by setting the control button 30, it is convenient to use the controller 5 to control the left servo motor 15, the right servo motor 10 and the fan 29. Holding the wrench 1, the fan 29 can blow on the target to achieve the dust removal effect, which is convenient for the subsequent disassembly and assembly of bolts and nuts. When the wrench 1 is in a vertical position relative to the support 7, and the bolt or nut to be disassembled or assembled can be rotated relatively easily, the protective sleeve 27 can be rotated in a circumferential direction to quickly rotate the bolt or nut, thereby improving the disassembly efficiency.

[0043] The wrench 1 includes a front rod 101 and a rear rod 102, with the front rod 101 in front and the rear rod 102 behind. A second conductive slip ring 35 is installed between the front rod 101 and the rear rod 102. The stator of the second conductive slip ring 35 is fixed to the front rod 101, and the rotor is fixed to the rear rod 102. The front rod 101 and the rear rod 102 are coaxially rotatably connected by the second conductive slip ring 35. A geared motor 36 with braking function is fixed to the front rod 101, and the shaft of the geared motor 36 is coaxially fixed with that of the rear rod 102. The geared motor 36 is electrically connected to the controller 5. The battery 6, controller 5, and control button 30 are fixed to the front rod 101. A first lighting lamp 31 is installed at the front end of the protective cylinder 27. The fan 29 is fixed to the front rod 101. The controller 5 is electrically connected to the stator of the second conductive slip ring 35. A second lighting lamp 32 and a third lighting lamp 33 are fixed to the upper and lower parts of the rear rod 102 in sequence. The rotor of the first conductive slip ring 34, the second lighting lamp 32, and the third lighting lamp 33 are electrically connected to the rotor of the second conductive slip ring 35.

[0044] Furthermore, when the wrench 1 is vertical relative to the support base 7, by holding the protective sleeve 27 and controlling the reduction motor 36 to rotate forward and backward, the rear rod 102 can actively drive the clamping mechanism 2 to rotate forward and backward, thereby quickly rotating the target bolts and nuts, thus improving work efficiency. The use of the first lighting lamp 31, the second lighting lamp 32 and the third lighting lamp 33 can illuminate the area to be cleaned and the area to be disassembled or installed, facilitating work and improving work efficiency.

For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
