Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal cutting technology, and in particular to a shearing device based on the processing of elevator counterweights. Background Technology
[0002] Elevator counterweights are key components that balance the weight of the elevator car during operation. They are usually made of cast iron or concrete, and their weight and position need to be precisely calculated to ensure that the elevator remains balanced when ascending and descending. Elevator counterweights are manufactured into blocks of materials such as cast iron or concrete through specific processes.
[0003] A search revealed Chinese Patent Publication No. CN218591924U, which discloses a shearing machine for producing elevator counterweight shells. The machine relates to the field of metal cutting technology and includes a workbench, a mounting frame, a cutting assembly, and a support device. The mounting frame includes a base, a vertical plate, and a horizontal plate. One end of the vertical plate is fixedly connected to the base, and the other end is fixedly connected to the horizontal plate. The cutting assembly includes a hydraulic cylinder and a cutting blade. The hydraulic cylinder is fixedly connected to the horizontal plate and drives the cutting blade to move towards or away from the base. The support device includes at least two vertical rods and a limiting assembly. The vertical rods are mounted on the base. The limiting assembly includes a limiting plate, which is fixedly connected to the base, and a limiting block is fixedly connected to the limiting plate.
[0004] The aforementioned patent specification mentions that "by setting a limiting component, the steel plate can be limited to prevent it from shaking during shearing operations, thereby improving the accuracy of the shearing operation." While the patent does use a limiting component to prevent shaking during shearing and improve accuracy, the waste generated after shearing is not treated. If this waste is not treated, it will occupy space, affect processing, pose safety hazards, and cause environmental pollution. Therefore, a shearing device based on elevator counterweight processing is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a shearing device based on elevator counterweight processing, which aims to improve the problem that if the waste chips after shearing are not treated, they will occupy space, affect processing, cause safety hazards and environmental pollution.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shearing device based on elevator counterweight processing, comprising a base, a cleaning mechanism installed inside the base, a processing mechanism fixedly connected to the top of the base, a limiting mechanism fixedly connected to the top of the base, and a buffer mechanism fixedly connected to the side of the top of the base away from the limiting mechanism.
[0007] The cleaning mechanism includes a cleaning plate, a reset assembly is fixedly connected to the outside of the cleaning plate, a winding shaft is rotatably connected to the inner wall of the base, two traction ropes are fixedly connected to the outside of the winding shaft, the other ends of the two traction ropes are fixedly connected to the outside of the cleaning plate, multiple slots are provided on the top of the base, and a collection trough is installed on the inner wall of the processing mechanism.
[0008] Through the above technical solution: the base is used to assemble and support all structures, the processing mechanism is used to cut the workpiece, the cleaning mechanism is used to clean up the debris generated during the processing, the limiting mechanism is used to limit the height of one end of the workpiece when it is positioned, and the buffer mechanism and the limiting mechanism are used together to limit the length of the workpiece.
[0009] The rotation of the winding shaft causes the two traction ropes to be wound up, which shortens the other end of the traction ropes, thereby pulling the cleaning plate to change position, so that the debris can be pushed into the inside of the collection tank for subsequent unified processing. The debris generated after processing can fall through the chute.
[0010] As a further description of the above technical solution:
[0011] The reset assembly includes multiple sliding shafts, the outer side of which is fixedly connected to the outside of the cleaning plate. A second spring is fixedly connected to the inner wall of each sliding shaft, and the other end of the second spring is fixedly connected to the inner wall of the base.
[0012] Through the above technical solution: the position change of the cleaning plate drives the position change of multiple sliding shafts, the position change of the sliding shafts causes the second spring to deform, and the inner wall of the base has a fixing effect on the other end of the second spring, so that the cleaning plate can be reset after cleaning, in preparation for the next cleaning.
[0013] As a further description of the above technical solution:
[0014] A motor is mounted on the outside of the base, and the drive end of the motor is fixedly connected to the outside of the take-up shaft.
[0015] The above technical solution involves starting the motor, which drives the winding shaft to rotate, thereby providing driving force to the winding shaft.
[0016] As a further description of the above technical solution:
[0017] The processing mechanism includes a support frame, the bottom of which is fixedly connected to the top of the base. A cylinder is installed on the inner wall of the support frame, and a moving plate is fixedly connected to the driving end of the cylinder.
[0018] Through the above technical solution: the base provides support and fixes the position of the support frame, the support frame fixes the installation position of the cylinder, and the cylinder is started. The position change of the cylinder drive end can drive the moving plate to change position, so as to provide the working position and support of the cutting structure.
[0019] As a further description of the above technical solution:
[0020] A cutting blade is installed at the bottom of the movable plate, and multiple telescopic rods are fixedly connected to the inner wall of the support frame. The other ends of the multiple telescopic rods are fixedly connected to the top of the movable plate.
[0021] Through the above technical solution: the position change of the moving plate drives the position change of the cutting blade, thereby enabling the cutting blade to process the workpiece. The position change of the moving plate enables the telescopic rod to follow the position change, thereby ensuring that the moving plate maintains its position stability during the position change process.
[0022] As a further description of the above technical solution:
[0023] The limiting mechanism includes two limiting plates. The top of the base has two limiting grooves. The inner wall of the limiting groove is rotatably connected to multiple rotating blocks. The bottom of the limiting plate is slidably connected to the inner wall of the limiting groove. The inner wall of the limiting plate has multiple slots. The inner walls of two slots are slidably connected to pressure plates.
[0024] Through the above technical solution: the limiting groove is used to allow the structures on both sides to slide on the inner wall and change their position, thereby changing the limiting size of the workpiece. The sliding position of the limiting structure is limited by the rotating block, so that the limiting plate can slide on the inner wall of the two limiting grooves. The height of the pressure plate position is changed by the change of the position of the slot and the pressure plate.
[0025] As a further description of the above technical solution:
[0026] The inner walls of the two limiting grooves are slidably connected to a fixing box, and the inner walls of the fixing box are slidably connected to a sliding plate.
[0027] Through the above technical solution, the fixed box can slide on the inner wall of the limiting groove, so that the sliding plate can slide on the inner wall of the fixed box, thereby limiting the position of one end of the workpiece.
[0028] As a further description of the above technical solution:
[0029] The sliding plate is externally fixedly connected to multiple springs, and the other ends of the multiple springs are fixedly connected to the inner wall of the fixed box.
[0030] Through the above technical solution: the position change of the sliding plate causes multiple springs to deform, and the position reset of the springs can cause the bottom of the sliding plate to press against the workpiece. The fixing box has the function of fixing the other end of the springs, so that the springs can be successfully reset later.
[0031] This utility model has the following beneficial effects:
[0032] 1. In this utility model, the rotation of the winding shaft can wind up the traction rope, so that the shortened traction rope can pull the cleaning plate to change position, thereby pushing the debris leaking from the chute. The position change of the cleaning plate drives the position change of multiple sliding shafts, thereby causing the second spring to deform. After the external traction force disappears, the reset of the second spring can pull the sliding shaft to reset, thereby driving the cleaning plate to reset. The processing of shearing waste can free up working space, which is convenient for subsequent operations. It can eliminate the risk of slipping and injury to personnel, reduce safety risks such as fire, and also avoid environmental pollution by harmful substances.
[0033] 2. In this utility model, the sliding plate moves upward, causing multiple springs to deform. The reset of the springs allows the surface of the sliding plate to continue to contact the workpiece, thereby maintaining stability at one end of the workpiece. By adjusting the engagement relationship between the multiple slots and the pressure plate, the restriction on the workpiece can be more closely aligned with the processing state, enabling the simultaneous shearing of multiple steel plates or the simultaneous shearing of two locations on the same steel plate.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a shearing device based on elevator counterweight processing, comprising a base 1 for assembling and supporting all structures. A cleaning mechanism 5 is installed inside the base 1 to clean debris generated during processing. A processing mechanism 2 is fixedly connected to the top of the base 1 for cutting the workpiece. A limiting mechanism 3 is fixedly connected to the top of the base 1 to limit the height of one end of the workpiece during positioning. A buffer mechanism 4 is fixedly connected to the side of the top of the base 1 away from the limiting mechanism 3, and the buffer mechanism 4, together with the limiting mechanism 3, is used to limit the length of the workpiece.
[0043] Specifically, the shearing device based on elevator counterweight processing uses base 1 as the assembly and load-bearing foundation, integrating cleaning, processing, limiting, and buffering mechanisms. The cleaning mechanism 5 is responsible for debris handling, the processing mechanism 2 performs cutting, the limiting mechanism 3 controls the workpiece height, and works in conjunction with the buffering mechanism 4 to limit the workpiece length, jointly ensuring the efficiency and precision of the shearing operation.
[0044] The cleaning mechanism 5 includes a cleaning plate 503, to which a reset assembly 505 is fixedly connected. A winding shaft 502 is rotatably connected to the inner wall of the base 1. Two traction ropes 504 are fixedly connected to the outer side of the winding shaft 502. Rotation of the winding shaft 502 causes the two traction ropes 504 to be wound up. The other ends of the two traction ropes 504 are fixedly connected to the outer side of the cleaning plate 503, causing the other ends of the traction ropes 504 to shorten, thereby pulling the cleaning plate 503 to change position. Multiple slots 507 are provided on the top of the base 1, allowing the debris generated after processing to fall through the slots 507. A collection trough 506 is installed on the inner wall of the processing mechanism 2, allowing the debris to be pushed into the collection trough 506 for subsequent unified processing.
[0045] Specifically, the cleaning mechanism 5, through the reset component 505, works in conjunction with the winding shaft 502 and the traction rope 504 to realize the movement operation of the cleaning plate 503. The design of the trough 507 on the top of the base 1 and the collection groove 506 on the inner wall of the processing mechanism 2 allows processing debris to fall into the collection groove 506 for unified processing, effectively improving the cleanliness and efficiency of the operation.
[0046] Reference Figure 2 The reset assembly 505 includes multiple sliding shafts 5051, which are externally fixedly connected to the outside of the cleaning plate 503. Changes in the position of the cleaning plate 503 cause changes in the position of the multiple sliding shafts 5051. A second spring 5052 is fixedly connected to the inner wall of each sliding shaft 5051. Changes in the position of the sliding shafts 5051 cause deformation of the second spring 5052. The other end of the second spring 5052 is fixedly connected to the inner wall of the base 1. A motor 501 is mounted externally on the base 1. The drive end of the motor 501 is fixedly connected to the outside of the take-up shaft 502. When the motor 501 is started, the rotation of the drive end of the motor 501 causes the take-up shaft 502 to rotate, thereby providing driving force to the take-up shaft 502.
[0047] Specifically, the reset assembly 505 is connected to the cleaning plate 503 via multiple sliding shafts 5051. Its position change causes the second spring 5052 to deform and generate elastic force. The motor 501 drives the winding shaft 502 to rotate, providing force for the winding of the traction rope 504, which in turn drives the cleaning plate 503 to move, thus realizing the cleaning action.
[0048] Reference Figure 4The processing mechanism 2 includes a support frame 201, the bottom of which is fixedly connected to the top of a base 1. The base 1 provides support and fixes the position of the support frame 201. A cylinder 202 is installed on the inner wall of the support frame 201. A moving plate 203 is fixedly connected to the drive end of the cylinder 202. Activating the cylinder 202 causes the moving plate 203 to move, providing a working position and support for the cutting structure. A cutting blade 204 is installed at the bottom of the moving plate 203. Changes in the position of the moving plate 203 cause changes in the position of the cutting blade 204, allowing the cutting blade 204 to process the workpiece. Multiple telescopic rods 205 are fixedly connected to the inner wall of the support frame 201. The other ends of the telescopic rods 205 are fixedly connected to the top of the moving plate 203. Changes in the position of the moving plate 203 cause the telescopic rods 205 to follow suit, thus maintaining the stability of the moving plate 203's position during these changes.
[0049] Specifically, the processing mechanism 2 uses the support frame 201 as the support base. The cylinder 202 drives the moving plate 203 to change position, providing a work station and support for the cutting blade 204. The moving plate 203 moves with the cutting blade 204 to realize workpiece processing. The telescopic rod 205 changes accordingly to keep the moving plate 203 stable and ensure cutting accuracy.
[0050] Reference Figure 2 and Figure 4 The limiting mechanism 3 includes two limiting plates 301. Two limiting grooves 303 are formed on the top of the base 1. The limiting grooves 303 allow the structures on both sides to slide along the inner wall, changing their position and thus altering the limiting dimensions of the workpiece. Multiple rotating blocks 304 are rotatably connected to the inner wall of the limiting grooves 303, limiting the sliding position of the limiting structure. The bottom of the limiting plates 301 is slidably connected to the inner wall of the limiting grooves 303. Multiple slots 305 are formed on the inner wall of the limiting plates 301. Pressure plates 302 are slidably connected to the inner walls of two slots 305. The height of the pressure plates 302 is changed by altering the positions of the slots 305 and pressure plates 302.
[0051] Specifically, the limiting mechanism 3 consists of a limiting plate 301, a limiting groove 303, etc. The limiting groove 303 allows the structure to slide and change the limiting size, the rotating block 304 locks the sliding position, and the pressure plate 302 moves in the slot 305 to adjust the height, together achieving precise positioning and size limitation of the workpiece.
[0052] Reference Figure 4 and Figure 5A fixed box 401 is slidably connected to the inner wall of the two limiting grooves 303. A sliding plate 402 is slidably connected to the inner wall of the fixed box 401. The fixed box 401 can slide on the inner wall of the limiting grooves 303, allowing the sliding plate 402 to slide on the inner wall of the fixed box 401, thereby limiting the position of one end of the workpiece. Multiple springs 403 are fixedly connected to the outside of the sliding plate 402. The other ends of the multiple springs 403 are fixedly connected to the inner wall of the fixed box 401. The position change of the sliding plate 402 causes the multiple springs 403 to deform. The return of the position of the springs 403 can cause the bottom of the sliding plate 402 to press against the workpiece.
[0053] Specifically, the fixed box 401 is slidably connected within the limiting groove 303, and the sliding plate 402 moves accordingly, together limiting the position of the workpiece. The movement of the sliding plate 402 causes the spring 403 to deform. When the spring 403 returns to its original position, it can press the workpiece, achieving stable positioning of one end of the workpiece.
[0054] Working principle: When cutting is required, the workpiece is installed on the top of the worktable, and then the cylinder 202 is activated. The position change of the driving end of the cylinder 202 causes the moving plate 203 to change position, so that the cutting blade 204 can cut the workpiece. During the movement of the moving plate 203, the telescopic rod 205 can keep the two ends of the moving plate 203 stable.
[0055] The motor 501 is started, and the rotation of the drive end of the motor 501 drives the winding shaft 502 to rotate. The rotation of the winding shaft 502 can wind up the traction rope 504, so that the traction rope 504 shortens and pulls the cleaning plate 503 to change position, thereby pushing the debris leaking from the trough 507, so that the debris can fall into the collection trough 506 for collection. The position change of the cleaning plate 503 drives the position change of multiple sliding shafts 5051, thereby causing the second spring 5052 to deform. After the external traction force disappears, the return of the second spring 5052 can pull the sliding shaft 5051 to return to its original position, thereby driving the cleaning plate 503 to return to its original position, preparing for the next cleaning. The treatment of shearing waste can free up working space, facilitate subsequent operations, eliminate the risk of personnel slipping and injury, reduce safety risks such as fire, and also avoid environmental pollution by harmful substances.
[0056] The fixed box 401 and the two limiting plates 301 slide on the inner wall of the limiting groove 303 and are adjusted in position. The fixed box 401 is positioned on both sides by four rotating blocks 304. One end of the workpiece is placed on the inner wall of the fixed box 401, so that the workpiece can move the sliding plate 402 upward, thereby causing multiple springs 403 to deform. The reset of the springs 403 can keep the surface of the sliding plate 402 in contact with the workpiece, thus keeping one end of the workpiece stable. By adjusting the engagement relationship between the multiple slots 305 and the pressure plate 302, the restriction on the workpiece can be more closely aligned with the processing state, so that multiple layers of steel plates can be sheared at the same time, or two places on the same steel plate can be sheared at the same time, avoiding one side from tilting or moving and mutually restricting each other.
[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
