Description

Technical Field

[0001] This utility model belongs to the field of disassembly and assembly tools, specifically relating to a lifting and unloading device for a six-sided top press top mallet. Background Technology

[0002] A six-sided top press is a type of mechanical equipment used for synthesizing superhard materials such as synthetic diamonds and lab-grown diamonds. It belongs to a subcategory of large-cavity presses. During the production process of a six-sided top press, due to production needs or damage to the top hammers, it is necessary to remove and replace the top hammers inside the press frequently. Because the space inside the six-sided top press is small, it is very inconvenient to remove the top hammers. Operators often use lifting tools to lift them out directly, but due to the difficulty in guiding them, the lifting process is very unstable and is prone to collisions, falls, and other problems. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a lifting and unloading device for the top hammer of a six-sided top press. This device can assist in the unloading and unloading of the top hammer of a six-sided top press. Through the adjustable support mechanism, in conjunction with the first winch, second winch, first steel cable, second steel cable, spring buckle, cantilever, universal ball joint, universal ball, auxiliary rod, linear drive, and platform, the operational stability and convenience of the top hammer unloading and unloading operation can be greatly improved.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lifting and unloading device for a six-sided top press hammer, comprising a T-shaped bracket, with casters installed at the bottom of the T-shaped bracket, a crossbeam installed at the top of the T-shaped bracket, and cantilevered arms welded to the sides of the crossbeam. A first winch and a second winch are installed at the top of the cantilevered arms, with a first steel cable and a second steel cable respectively wound and connected to the outer sides of the drums of the first winch and the second winch. One end of the first steel cable and the second steel cable is connected to a connecting mechanism. The second steel cable connection mechanism is connected to the support mechanism. The support mechanism includes an outer ring, on the side of which a hydraulic cylinder is mounted. One end of the piston rod of the hydraulic cylinder is connected to an inner clamping plate. Four sets of universal ball joint seats are provided around the hydraulic cylinder on the side of the outer ring. The universal ball joint seats have a rollable universal ball inside. The universal ball is connected to an auxiliary rod. Steel cable connection rings are provided at the top and bottom of the outer ring. A guide wheel support mechanism is connected to the bottom of the cantilever. A lifting support mechanism is installed on the T-shaped bracket.

[0005] The beneficial effects of this utility model are as follows: When using this device, it is pushed to the outside of the six-sided top press machine via the universal wheels. Then, the first and second winches are controlled to unwind, releasing the first and second steel cables. The operator holds the auxiliary rod and guides the support mechanism to penetrate into the inside of the six-sided top press machine, so that the outer ring of the support mechanism is placed on the outside of the top hammer to be disassembled. The hydraulic cylinder is then controlled to push the inner clamping plate to firmly clamp the top hammer. At this time, the spring buckle on the forked steel cable at one end of the first steel cable can be connected to the cantilever. After the top hammer is disassembled, the second winch can be controlled to rewind, while the first winch continues to unwind. Supported by the first and second steel cables, the top hammer is removed from the six-sided top press by the auxiliary rod-guided support mechanism and the traction of the second winch. The direction of movement during the removal process is towards the platform. Since it can be guided by the auxiliary rod, the movement path of the top hammer can be better controlled, avoiding frequent collisions with the main body of the six-sided top press. The universal ball joint and the universal ball can rotate, which facilitates the switching of the angle of the auxiliary rod. The first and second steel cables effectively provide traction support to the support mechanism under the fulcrum of the steel cable guide pulley block, and prevent it from swinging excessively, which greatly improves the stability of the operation of this device.

[0006] When not in use, the platform is folded. When in use, the control motor drives the platform to rotate and lower it to a horizontal position. The support plate provides some support for the platform. Based on the position of the disassembled top hammer, the linear drive is controlled to raise the support plate and the platform to a height close to the installation position of the top hammer. When the operator pulls the support mechanism out from the inside of the six-sided top press, and guides the support mechanism to the top of the platform, the first and second winches are stopped. At this time, the support mechanism and the top hammer held inside can be placed directly on the platform. The hydraulic cylinder can then be controlled to release the clamping and fixing of the top hammer by the inner clamping plate. The support mechanism is pulled away from the outside of the top hammer by the auxiliary rod. At this time, the top hammer can be lifted away by the lifting equipment, improving the convenience of lifting the top hammer.

[0007] To ensure a secure connection between the first and second steel cables and the support mechanism:

[0008] As a further improvement to the above technical solution: the connecting mechanism includes a Y-shaped connector connected to the first steel cable and the second steel cable, the other end of the Y-shaped connector being connected to the branched steel cable, the other end of the branched steel cable being connected to a spring buckle, and the steel cable connecting ring being connected to the spring buckle on the branched steel cable at one end of the second steel cable.

[0009] The beneficial effects of this improvement are: both the first and second steel cables can be connected to the cable connecting ring through two sets of spring buckles, which facilitates the connection and separation of the first and second steel cables from the support mechanism, while improving the stability of the connection with the support mechanism.

[0010] To facilitate receiving the removed top hammer:

[0011] As a further improvement to the above technical solution: the lifting support mechanism includes a linear driver mounted on a T-shaped bracket, a support plate connected to one side of the linear driver, a rotating mounting seat mounted on the top of the support plate, and the rotating mounting seat being rotatably connected to the platform.

[0012] Depending on the location of the disassembled top hammer, the linear drive can be controlled to raise the support plate and the platform to a height close to the installation position of the top hammer, making it convenient to receive the removed top hammer.

[0013] For folding and laying down the tabletop:

[0014] As a further improvement to the above technical solution: a motor is mounted on the side of the rotating mounting base, and the output shaft of the motor is connected to the support plate.

[0015] When this device is not in use, the platform is folded. When this device is in use, the control motor drives the platform to rotate and lower it to a horizontal position.

[0016] To accommodate the positional changes of the first and second steel cables caused by the displacement and angle changes of the support mechanism during the removal of the top hammer:

[0017] As a further improvement to the above technical solution: the guide wheel support mechanism includes a suspension rope connected to the bottom of the cantilever, a pulley mounting frame connected to the bottom of the suspension rope, and a steel cable guide pulley assembly installed on the inner side of the pulley mounting frame.

[0018] The pulley mounting bracket can be rotated by the suspension rope to adapt to the positional changes of the first and second steel cables caused by the displacement and angle changes of the support mechanism during the removal of the top hammer, so that the steel cable guide pulley block can maintain contact and guidance of the first and second steel cables.

[0019] For quick assembly and disassembly of the auxiliary rod:

[0020] As a further improvement to the above technical solution: the side of the universal ball is connected to an auxiliary rod internal thread joint, and the auxiliary rod internal thread joint is threadedly connected to the auxiliary rod.

[0021] The swivel ball joint is threadedly connected to the auxiliary rod via an internal threaded connector. The auxiliary rod can be quickly detached from one internal threaded connector and quickly connected to the internal threaded connector on another swivel ball joint.

[0022] To improve the stability of the inner clamping plate in holding the top hammer:

[0023] As a further improvement to the above technical solution: the inner side of the inner clamping plate is provided with a rubber anti-slip pad.

[0024] The beneficial effects of this improvement are: the rubber anti-slip pad is used to increase the friction between the inner clamping plate and the top hammer held by it, thereby improving the stability of clamping.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] like Figure 1-5As shown, a lifting and unloading device for a six-sided top press includes a T-shaped bracket 1. A caster wheel 2 is mounted on the bottom of the T-shaped bracket 1, and a crossbeam 3 is mounted on the top of the T-shaped bracket 1. A cantilever 20 is welded to the sides of the crossbeam 3. A first winch 4 and a second winch 5 are mounted on the top of the cantilever 20. A first steel cable 6 and a second steel cable 7 are respectively wound and connected to the outer sides of the drums of the first winch 4 and the second winch 5. One end of the first steel cable 6 and the second steel cable 7 is connected to a connecting mechanism, and the connecting mechanism of the second steel cable 7 is connected to a support mechanism 11. The support mechanism 11 includes an outer ring 12, a hydraulic cylinder 13 is mounted on the side of the outer ring 12, one end of the piston rod of the hydraulic cylinder 13 is connected to the inner clamping plate 14, four sets of universal ball joint seats 15 are provided around the hydraulic cylinder 13 on the side of the outer ring 12, and a rotatable universal ball 16 is provided inside the universal ball joint seat 15. The universal ball 16 is connected to the auxiliary rod 18. The top and bottom of the outer ring 12 are provided with steel cable connecting rings 19. The bottom of the cantilever 20 is connected to a guide wheel support mechanism, and a lifting support mechanism is installed on the T-shaped bracket 1.

[0034] When using this device, push it to the outside of the six-sided top press using the casters 2. Then, control the first winch 4 and the second winch 5 to unwind, releasing the first steel cable 6 and the second steel cable 7. The operator holds the auxiliary rod 18 and guides the support mechanism 11 into the inside of the six-sided top press, so that the outer ring 12 of the support mechanism 11 is placed on the outside of the top hammer to be disassembled. Control the hydraulic cylinder 13 to push the inner clamping plate 14 to firmly clamp the top hammer. At this time, the spring buckle 10 on the forked steel cable 9 at one end of the first steel cable 6 can be connected to the cantilever 20. After disassembling the top hammer, control the second winch 5 to rewind, while the first winch 4 continues to unwind, releasing the first steel cable 6 and the second steel cable 7. Supported by the two steel cables 7, the top hammer is removed from the six-sided top press by the auxiliary rod 18 and the traction of the second winch 5. The direction of movement during the removal process is towards the platform 27. Since it can be guided by the auxiliary rod 18, the movement path of the top hammer can be better controlled, avoiding frequent collisions with the main body of the six-sided top press. The universal ball joint 15 and the universal ball 16 can rotate, which facilitates the switching of the angle of the auxiliary rod 18. The first steel cable 6 and the second steel cable 7 effectively provide traction support for the support mechanism 11 under the fulcrum of the steel cable guide pulley block 23, and prevent it from swinging excessively, which greatly improves the stability of the operation of this device.

[0035] When the device is not in use, the platform 27 is folded. When the device is in use, the control motor 28 drives the platform 27 to rotate and lower it to a horizontal position. The support plate 25 provides some support for the platform 27. According to the position of the disassembled top hammer, the linear drive 24 is controlled to drive the support plate 25 and the platform 27 to rise to a height close to the installation position of the top hammer. When the operator pulls the support mechanism 11 out from the inside of the six-sided top press, and guides the support mechanism 11 to the top of the platform 27, the first winch 4 and the second winch 5 are stopped. At this time, the support mechanism 11 and the top hammer clamped inside can be placed directly on the platform 27. The hydraulic cylinder 13 can be controlled to release the clamping and fixing of the top hammer by the inner clamping plate 14. The support mechanism 11 is pulled away from the outside of the top hammer by the auxiliary rod 18. At this time, the top hammer can be lifted away by the lifting equipment, which improves the convenience of lifting the top hammer.

[0036] The connecting mechanism includes a Y-shaped connector 8 connected to the first steel cable 6 and the second steel cable 7. The other end of the Y-shaped connector 8 is connected to the branched steel cable 9. The other end of the branched steel cable 9 is connected to the spring buckle 10. The steel cable connecting ring 19 is connected to the spring buckle 10 on the branched steel cable 9 at one end of the second steel cable 7.

[0037] Both the first steel cable 6 and the second steel cable 7 can be connected to the steel cable connecting ring 19 through two sets of spring buckles 10, which facilitates the connection and separation between the first steel cable 6, the second steel cable 7 and the support mechanism 11, while improving the stability of the connection with the support mechanism 11.

[0038] The lifting support mechanism includes a linear actuator 24 mounted on a T-shaped bracket 1. A support plate 25 is connected to one side of the linear actuator 24. A rotating mounting seat 26 is mounted on the top of the support plate 25. The rotating mounting seat 26 is rotatably connected to the platform 27.

[0039] Depending on the location of the disassembled top hammer, the linear drive 24 can be controlled to drive the support plate 25 and the platform 27 to rise to a height close to the installation position of the top hammer, so as to facilitate the receiving of the removed top hammer.

[0040] A motor 28 is mounted on the side of the rotating mounting base 26, and the output shaft of the motor 28 is connected to the support plate 25.

[0041] When the device is not in use, the platform 27 is in a folded state. When the device is in use, the control motor 28 drives the platform 27 to rotate and lower it to a horizontal position.

[0042] The guide wheel support mechanism includes a suspension rope 21 connected to the bottom of the cantilever 20, a pulley mounting bracket 22 connected to the bottom of the suspension rope 21, and a steel cable guide pulley group 23 installed on the inner side of the pulley mounting bracket 22.

[0043] The pulley mounting bracket 22 can be rotated by the suspension rope 21 to adapt to the positional changes of the first steel cable 6 and the second steel cable 7 caused by the displacement and angle changes of the support mechanism 11 during the removal of the top hammer, so that the steel cable guide pulley block 23 maintains contact with and guides the first steel cable 6 and the second steel cable 7.

[0044] The side of the universal ball 16 is connected to an auxiliary rod internal thread connector 17, which is threadedly connected to the auxiliary rod 18.

[0045] The omnidirectional ball 16 is threadedly connected to the auxiliary rod 18 via the auxiliary rod internal thread connector 17. The auxiliary rod 18 can be quickly separated from one auxiliary rod internal thread connector 17 and quickly connected to the auxiliary rod internal thread connector 17 on another omnidirectional ball 16.

[0046] The inner side of the inner clamping plate 14 is provided with a rubber anti-slip pad.

[0047] The rubber anti-slip pad is used to increase the friction between the inner clamping plate 14 and the top hammer held by it, thereby improving the stability of the clamping.

[0048] The working principle and usage process of this utility model are as follows: When using this device, push it to the outside of the six-sided top press machine via the universal wheel 2. Then, control the first winch 4 and the second winch 5 to unwind the first steel cable 6 and the second steel cable 7. The operator holds the auxiliary rod 18 and guides the support mechanism 11 into the inside of the six-sided top press machine, so that the outer ring 12 in the support mechanism 11 is placed on the outside of the top hammer to be disassembled. Control the hydraulic cylinder 13 to push the inner clamping plate 14 to firmly clamp the top hammer. At this time, the spring buckle 10 on the forked steel cable 9 at one end of the first steel cable 6 can be connected to the cantilever 20. After the top hammer is disassembled, control the second winch 5 to rewind, while the first winch 4 continues to unwind the first steel cable 6 and the second steel cable 7. Supported by cable 7, the top hammer is removed from the six-sided top press by the auxiliary rod 18 guiding the support mechanism 11 in conjunction with the traction of the second winch 5. The movement direction during removal is towards the platform 27. Because the auxiliary rod 18 can guide the movement, the movement path of the top hammer can be better controlled, avoiding frequent collisions with the main body of the six-sided top press. The universal ball joint 15 and universal ball 16 are rotatable, facilitating the switching of the angle of the auxiliary rod 18. The first steel cable 6 and the second steel cable 7, under the fulcrum of the steel cable guide pulley block 23, effectively provide traction support to the support mechanism 11 and prevent excessive swaying, greatly improving the operational stability of the device. When the device is not in use, the platform 27 is in a folded state. When the device is in use, the control motor 28 drives the platform 27 to rotate and lower it to a horizontal position. The support plate 25 provides some support for the platform 27. According to the position of the disassembled top hammer, the control linear drive 24 drives the support plate 25 and the platform 27 to rise to a height close to the installation position of the top hammer. When the operator pulls the support mechanism 11 out from the inside of the six-sided top press, and guides the support mechanism 11 above the platform 27, the control first winch 4 and second winch 5 stop running. At this time, the support mechanism 11 and the top hammer clamped inside can be placed directly on the platform 27. The control hydraulic cylinder 13 can then release the clamping fixation of the top hammer by the inner clamping plate 14. The auxiliary rod 18 pulls the support mechanism 11 to move it away from the outside of the top hammer. At this time, it can be used. The lifting device removes the top hammer, allowing for the removal of the next top hammer. Because multiple sets of universal ball joints 15 and universal balls 16 are provided, and the universal balls 16 are threadedly connected to the auxiliary rod 18 via the auxiliary rod internal thread connector 17, the universal ball 16 connected to the auxiliary rod 18 can be selected according to the position of the top hammer being removed. In summary, this device assists in the removal and unloading of the top hammers from a six-sided top press. Through the adjustable support mechanism 11, along with the first winch 4, second winch 5, first steel cable 6, second steel cable 7, spring buckle 10, cantilever 20, universal ball joints 15, universal balls 16, auxiliary rod 18, linear actuator 24, and platform 27, the operational stability and convenience of the top hammer removal and unloading operation are greatly improved.
