Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to a lifting method and an elevator for building construction. Background Art

[0002] A lift refers to a lifting mechanical equipment or device that is a platform or semi-enclosed platform for carrying people or goods up and down in a vertical channel. It is commonly used in the field of construction. The lift includes a base, a lifting platform, a cage, scissor arms arranged in an inward and outward cross pattern on both sides of the base, and a driving mechanism that drives the scissor arms to expand or close relative to each other. Workers can stand in the cage to perform high-altitude operations.

[0003] However, the existing lifting methods and elevators used in construction are not convenient for horizontal movement of the cage when in use, which limits the range of workers' high-altitude operations. In addition, the elevator needs to be lowered to the ground and moved before it can be raised again for operation, which is not convenient and fast enough and affects the efficiency of high-altitude operations. Summary of the invention

[0004] The present invention aims at the technical problems existing in the prior art and provides a lifting method and a lift for construction to solve the problem that the existing lifting method and lift for construction are not convenient for horizontal movement of the cage when in use, thereby limiting the range of workers' aerial work, and the lift needs to be lowered to the ground and moved before it can be raised again for work, which is not convenient and fast enough and affects the efficiency of aerial work.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A lifting method and a lifting machine for construction, comprising the following steps:

[0006] S1: Preset, pre-prepare the lift and move the lift to the desired position;

[0007] S2: lifting and lowering. After step S1, the lift rises. When it reaches the specified height, the worker performs aerial work. After completing the aerial work, the lift is lowered to the ground.

[0008] S3: Monitoring. In step S2, during the lifting process of the elevator, the stability and safety of the elevator are continuously monitored to ensure that no abnormal situation occurs. When an abnormal situation is found, the lifting operation is immediately stopped, and inspection and maintenance are carried out.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] A construction lift, based on the above-mentioned construction lift method, comprises a base, a scissor arm, a lifting platform and a cage, wherein the cage is connected to the top of the lifting platform via a transverse movement mechanism, the extension and retraction of the scissor arm is driven by a driving mechanism, and a side wall of the lifting platform is provided with a counterweight mechanism for counterweighting after the cage moves;

[0011] The counterweight mechanism includes a mounting groove provided on the side wall of the lifting platform, and a counterweight plate is inserted into the mounting groove. A plurality of balls arranged in an array are provided at the bottom of the mounting groove, and the movement of the counterweight plate is pulled by a pulling mechanism.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that it is convenient to move the cage laterally during high-altitude operations, which can improve the efficiency of high-altitude operations. At the same time, during the lateral movement of the cage, the counterweight plate can be pulled along the installation groove to move in the opposite direction of the lateral movement of the cage, and the counterweight operation can be performed, thereby avoiding the shift of the center of gravity. Moreover, the closer the workers are to the two sides of the cage, the greater the distance for fine-tuning the counterweight plate, thereby making the counterweight effect of the cage better, safer and more reliable.

[0013] Furthermore, the transverse movement mechanism includes two symmetrically arranged first fixed blocks and two symmetrically arranged second fixed blocks fixedly connected to the top of the lifting platform, and the opposite side walls of the two first fixed blocks are fixedly connected to the guide rod, the side walls of the guide rod are sleeved with the first moving block, and the first moving block is fixed to the bottom of the cage, the opposite side walls of the two second fixed blocks are rotatably connected to the first threaded rod, and the side walls of the first threaded rod are threadedly connected to the second moving blocks, the second moving blocks are fixed to the bottom of the cage, and the side wall of one of the second fixed blocks is fixedly connected to the first motor.

[0014] The beneficial effect of adopting the above further scheme is that when workers are working at high altitudes and the cage needs to be moved laterally, the first motor is started, and the rotation of the first motor drives the rotation of the first threaded rod, thereby driving the second moving block and the first moving block to move, and then driving the cage to perform a transverse movement operation.

[0015] Furthermore, the pulling mechanism includes two symmetrically arranged T-shaped plates fixedly connected to both sides of the lifting platform, and the side walls of each T-shaped plate are rotatably connected to a conveying wheel through a first rotating shaft, the side walls of the conveying wheel are slidably connected to a pull rope, and the two ends of the pull rope are respectively fixed to the two sides of the counterweight plate, the side walls of the second moving block are fixedly connected to a connecting plate, and the connecting plate is sleeved on the side walls of the pull rope, the side walls of the pull rope are fixedly sleeved with two symmetrically arranged fixing rings, and a first spring is fixedly connected between each fixing ring and the connecting plate; the side walls of the T-shaped plates are provided with a conveying mechanism for conveying the pull rope.

[0016] The beneficial effect of adopting the above further scheme is that when the second moving block moves, it can move synchronously by pulling the pull rope through the first spring, and can pull the counterweight plate along the installation groove to move in the opposite direction of the lateral movement of the cage, so that the counterweight operation can be performed, thereby avoiding the shift of the center of gravity and being safer and more reliable.

[0017] Furthermore, the conveying mechanism includes a second motor fixedly connected to the side wall of the T-shaped plate, and the output end of the second motor is fixed to one end of the first rotating shaft, the bottom of the cage is rotatably connected to a rotating plate through a rotating mechanism, and the rotation of the rotating plate is driven by a driving mechanism, and the top of the lifting platform is fixedly connected to two symmetrically arranged L-shaped blocks, and a distance sensor is fixedly inserted at the top of each L-shaped block.

[0018] The beneficial effect of adopting the above further scheme is that after the cage moves horizontally, when the workers move to the two sides of the cage, the rotating plate can be driven to rotate downward by the rotating mechanism, and the distance sensor is used to detect the distance after the rotating plate is rotated. When the workers are closer to the two sides of the cage, the angle of rotation of the rotating plate can be made larger. At this time, the distance sensor detects that the distance of the rotating plate is closer. At this time, the second motor can be started. The rotation of the second motor drives the rotation of the first rotating shaft and the conveying wheel, thereby driving the pull rope for conveying. At the same time, the first spring is compressed. At this time, the counterweight plate can be pulled by the pull rope to continue moving for fine-tuning, and when the workers are closer to the two sides of the cage, the distance of fine-tuning of the counterweight plate is made larger, thereby making the counterweight effect of the cage better, safer and more reliable.

[0019] Furthermore, the rotating mechanism includes two symmetrically arranged support blocks fixedly connected to the bottom of the cage, and the rotating plate is rotatably connected to the opposite side walls of the two support blocks through a second rotating shaft, the side wall fixed sleeve of the second rotating shaft is provided with a gear, and the side wall of the support block is connected with a rack through a first reset mechanism, and the rack is meshing with the gear.

[0020] The beneficial effect of adopting the above further solution is that when the rotating plate rotates, the gear can be driven to rotate through the second rotating shaft, and at the same time, the rack is pushed to move.

[0021] Furthermore, the pushing mechanism includes multiple movable plates, and the side walls of each movable plate are fixedly connected with an L-shaped pushing plate, each of the movable plates is connected to the bottom of the cage through a second reset mechanism, and the top of each of the movable plates is fixedly connected with a fixed column, and the fixed column is set through the bottom of the cage.

[0022] The beneficial effect of adopting the above further scheme is that after the cage moves horizontally, when the workers move to the two sides of the cage, they will step on the fixed columns, thereby driving the movable plate and the push plate to move downward through the fixed columns, so that the push plate and the top of the rotating plate are abutted, thereby pushing the rotating plate to rotate downward along the second axis.

[0023] Furthermore, the first reset mechanism includes two symmetrically arranged connecting blocks fixedly connected to the side walls of the supporting block, and the opposite side walls of the two connecting blocks are fixedly connected to two symmetrically arranged fixing rods, the side wall of each fixing rod is sleeved with a sliding block, the sliding block is fixed to the side wall of the rack, and the side wall of each fixing rod is sleeved with a second spring.

[0024] The beneficial effect of adopting the above further solution is that it plays a guiding and resetting role in the movement of the rack.

[0025] Furthermore, the second resetting mechanism includes two symmetrically arranged T-shaped guide rods inserted at the bottom of each movable plate, the upper ends of the T-shaped guide rods are fixed to the bottom of the cage, and the side walls of each T-shaped guide rod are sleeved with a third spring.

[0026] The beneficial effect of adopting the above further solution is that it plays a guiding and resetting role in the movement of the movable plate.

[0027] Furthermore, the driving mechanism includes a support rod fixedly connected to the side wall of the scissors arm, and two symmetrically arranged fixed plates on the top of the base, the opposite side walls of the two fixed plates are rotatably connected to a U-shaped block through a third rotating shaft, and the side wall of the U-shaped block is fixedly connected to a third motor, the output end of the third motor is fixedly connected to a second threaded rod, and the side wall of the second threaded rod is threadedly connected to a threaded tube, the other end of the threaded tube is fixedly connected to a ring, and the ring is sleeved on the side wall of the support rod and rotatably connected to the side wall of the support rod.

[0028] The beneficial effect of adopting the above further scheme is that when the cage needs to be raised or lowered, the third motor can be started, and the rotation of the third motor drives the rotation of the second threaded rod, thereby driving the threaded tube to move. At the same time, the U-shaped block can rotate along the third rotating shaft, and the ring can rotate along the support rod, so as to realize the expansion and contraction of the scissor arms and thus realize the lifting and lowering of the cage.

[0029] The beneficial effects of the present invention are:

[0030] 1. By setting up a transverse movement mechanism and a pulling mechanism, when workers are working at high altitudes and need to move the cage transversely, the first motor is started, and the rotation of the first motor drives the rotation of the first threaded rod, thereby driving the second moving block and the first moving block to move, and then driving the cage to move transversely. At the same time, when the second moving block moves, it can pull the pull rope through the first spring to move synchronously, and can pull the counterweight plate along the installation groove to move in the opposite direction of the transverse movement of the cage, so that the counterweight operation can be performed, thereby avoiding the shift of the center of gravity, which is safer and more reliable.

[0031] 2. By setting up a conveying mechanism, etc., after the cage moves horizontally, when the workers move to both sides of the cage, they will step on the fixed column, thereby driving the moving plate and the push plate to move downward through the fixed column, and the third spring is compressed. At the same time, the push plate is abutted against the top of the rotating plate, thereby pushing the rotating plate to rotate downward along the second rotating axis, and the distance sensor is used to detect the distance after the rotating plate rotates. When the worker is closer to both sides of the cage, the angle of rotation of the rotating plate can be greater. At this time, the distance sensor detects that the distance of the rotating plate is closer, and the second motor can be started. The rotation of the second motor drives the rotation of the first rotating shaft and the conveying wheel, thereby driving the pull rope for conveying. At the same time, the first spring is compressed. At this time, the counterweight plate can be pulled by the pull rope to continue moving for fine-tuning, and when the worker is closer to both sides of the cage, the distance of the fine-tuning of the counterweight plate is greater, thereby making the counterweight effect of the cage better, safer and more reliable.

[0032] 3. By setting up a driving mechanism, when the cage needs to be lifted or lowered, the third motor can be started. The rotation of the third motor drives the rotation of the second threaded rod, thereby driving the threaded tube to move. At the same time, the U-shaped block can rotate along the third rotating shaft, and the ring can rotate along the support rod, so as to realize the expansion and contraction of the scissor arms and thus realize the lifting and lowering of the cage.

DETAILED DESCRIPTION

[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0046] A lift refers to a lifting mechanical equipment or device that is a platform or semi-enclosed platform for carrying people or goods up and down in a vertical channel. It is commonly used in the field of construction. The lift includes a base, a lifting platform, a cage, scissor arms arranged in an inward and outward cross pattern on both sides of the base, and a driving mechanism that drives the scissor arms to expand or close relative to each other. Workers can stand in the cage to perform high-altitude operations.

[0047] After an in-depth investigation and study of the use of the elevator, the inventor found that the existing lifting method and elevator for construction are not convenient for horizontal movement of the cage when in use, which limits the range of workers' high-altitude operations. In addition, the elevator needs to be lowered to the ground and moved before it can be raised again for operation, which is not convenient and fast enough and affects the efficiency of high-altitude operations. In response to this, the inventor proposed a lifting method and elevator for construction to solve the above problems.

[0048] The present invention provides the following preferred embodiments

[0049] like Figure 1-Figure 10 As shown, a lifting method and a lifting machine for construction, comprising the following steps:

[0050] S1: Preset, pre-prepare the lift and move the lift to the desired position;

[0051] S2: lifting and lowering. After step S1, the lift rises. When it reaches the specified height, the worker performs aerial work. After completing the aerial work, the lift is lowered to the ground.

[0052] S3: Monitoring. In step S2, during the lifting process of the elevator, the stability and safety of the elevator are continuously monitored to ensure that no abnormal situation occurs. When an abnormal situation is found, the lifting operation is immediately stopped, and inspection and maintenance are carried out.

[0053] A construction lift, based on the above construction lift method, comprises a base 101, a scissor arm 102, a lifting platform 103 and a cage 104, wherein the cage 104 is connected to the top of the lifting platform 103 via a transverse movement mechanism, the extension and retraction of the scissor arm 102 is driven by a driving mechanism, and a side wall of the lifting platform 103 is provided with a counterweight mechanism for counterweighting after the cage 104 moves;

[0054] The counterweight mechanism includes a mounting groove 1001 provided on the side wall of the lifting platform 103, and a counterweight plate 1003 is inserted in the mounting groove 1001. A plurality of ball bearings 1002 arranged in an array are provided at the bottom of the mounting groove 1001. The ball bearings 1002 are provided to facilitate the movement of the counterweight plate 1003, and the movement of the counterweight plate 1003 is pulled by a pulling mechanism. When working at high altitude, it is convenient to move the cage 104 horizontally, which can improve the efficiency of high-altitude operations. At the same time, in the process of the horizontal movement of the cage 104, the counterweight plate 1003 can be pulled along the mounting groove 1001 to move in the opposite direction of the horizontal movement of the cage 104, and the counterweight operation can be performed, thereby avoiding the shift of the center of gravity. Moreover, when the workers are closer to the two sides of the cage 104, the distance of fine-tuning of the counterweight plate 1003 is larger, so that the counterweight effect of the cage 104 is better, safer and more reliable.

When the workers are working at high altitude, when it is necessary to move the cage 104 transversely, the first motor 207 is started, and the rotation of the first motor 207 drives the rotation of the first threaded rod 204, thereby driving the second moving block 206 and the first moving block 205 to move, and then driving the cage 104 to perform transverse movement operation.

The side wall of the T-shaped plate 301 is provided with a conveying mechanism for conveying the pull rope 304. When the second moving block 206 moves, the pull rope 304 can be pulled by the first spring 307 to move synchronously, and the counterweight plate 1003 can be pulled along the installation groove 1001 to move in the opposite direction of the lateral movement of the cage 104, so that the counterweight operation can be performed, thereby avoiding the shift of the center of gravity, and being safer and more reliable.

[0057] In this embodiment, Figure 7-Figure 9As shown, the conveying mechanism includes a second motor 401 fixedly connected to the side wall of the T-shaped plate 301, and the output end of the second motor 401 is fixed to one end of the first rotating shaft 302, the bottom of the cage 104 is rotatably connected to a rotating plate 404 through a rotating mechanism, and the rotation of the rotating plate 404 is driven by a driving mechanism, and the top of the lifting platform 103 is fixedly connected to two symmetrically arranged L-shaped blocks 405, and the top of each L-shaped block 405 is fixedly inserted with a distance sensor 406. After the cage 104 moves horizontally, when the workers move to the two sides of the cage 104, the rotating plate 404 can be driven to rotate downward by the rotating mechanism, and the rotation of the rotating plate 404 is detected by the distance sensor 406. The distance after movement, when the workers are closer to the two sides of the cage 104, the angle of rotation of the rotating plate 404 can be larger. At this time, the distance sensor 406 detects that the distance of the rotating plate 404 is closer. At this time, the second motor 401 can be started, and the rotation of the second motor 401 drives the rotation of the first rotating shaft 302 and the conveying wheel 303, thereby driving the pull rope 304 for conveying. At the same time, the first spring 307 is compressed. At this time, the counterweight plate 1003 can be pulled by the pull rope 304 to continue to move for fine-tuning, and the closer the workers are to the two sides of the cage 104, the larger the distance of fine-tuning of the counterweight plate 1003, thereby making the counterweight effect of the cage 104 better, safer and more reliable.

[0058] In this embodiment, Figure 7 and Fig. 9 As shown, the rotating mechanism includes two symmetrically arranged support blocks 402 fixedly connected to the bottom of the cage 104, and the rotating plate 404 is rotatably connected to the opposite side walls of the two support blocks 402 through the second rotating shaft 403, the side wall fixed sleeve of the second rotating shaft 403 is provided with a gear 501, and the side wall of the support block 402 is connected with a rack 502 through a first reset mechanism, and the rack 502 is meshed with the gear 501. When the rotating plate 404 rotates, it can drive the gear 501 to rotate through the second rotating shaft 403, and at the same time, push the rack 502 to move.

[0059] In this embodiment, Figure 4 and Figure 7 As shown, the pushing mechanism includes a plurality of movable plates 701, and the side walls of each movable plate 701 are fixedly connected with an L-shaped pushing plate 703, each movable plate 701 is connected to the bottom of the cage 104 through a second reset mechanism, and the top of each movable plate 701 is fixedly connected with a fixed column 702, and the fixed column 702 runs through the bottom of the cage 104. After the cage 104 moves horizontally, when the workers move to the two sides of the cage 104, they will step on the fixed column 702, thereby driving the movable plate 701 and the pushing plate 703 to move downward through the fixed column 702, so that the pushing plate 703 is against the top of the rotating plate 404, thereby being able to push the rotating plate 404 to rotate downward along the second rotating shaft 403.

[0060] In this embodiment, Fig. 9 As shown, the first reset mechanism includes two symmetrically arranged connecting blocks 601 fixedly connected to the side walls of the supporting block 402, and the opposite side walls of the two connecting blocks 601 are fixedly connected to two symmetrically arranged fixing rods 602, and the side wall of each fixing rod 602 is sleeved with a slider 603, and the slider 603 is fixed to the side wall of the rack 502, and the side wall of each fixing rod 602 is sleeved with a second spring 604, which guides and resets the movement of the rack 502.

[0061] In this embodiment, Figure 7 As shown, the second resetting mechanism includes two symmetrically arranged T-shaped guide rods 801 inserted at the bottom of each movable plate 701, the upper end of the T-shaped guide rod 801 is fixed to the bottom of the cage 104, and the side wall of each T-shaped guide rod 801 is sleeved with a third spring 802, which guides and resets the movement of the movable plate 701.

[0062] In this embodiment, Figure 6 As shown, the driving mechanism includes a support rod 901 fixedly connected to the side wall of the scissor arm 102, and two symmetrically arranged fixing plates 902 on the top of the base 101, the opposite side walls of the two fixing plates 902 are rotatably connected to a U-shaped block 904 through a third rotating shaft 903, and the side wall of the U-shaped block 904 is fixedly connected to a third motor 905, the output end of the third motor 905 is fixedly connected to a second threaded rod 906, and the side wall of the second threaded rod 906 is threadedly connected to a threaded tube 907, and the other end of the threaded tube 907 is fixedly connected to a ring 9 08, and the ring 908 is sleeved on the side wall of the support rod 901 and is rotatably connected to the side wall of the support rod 901. When the cage 104 needs to be lifted or lowered, the third motor 905 can be started. The rotation of the third motor 905 drives the rotation of the second threaded rod 906, thereby driving the threaded tube 907 to move. At the same time, the U-shaped block 904 can rotate along the third rotating shaft 903, and the ring 908 can rotate along the support rod 901, so as to realize the expansion and contraction of the scissor arm 102, thereby realizing the lifting and lowering of the cage 104.

[0063] The specific method of use of the present invention is as follows:

[0064] When in use, first, when the cage 104 needs to be lifted or lowered, the third motor 905 can be started, and the rotation of the third motor 905 drives the rotation of the second threaded rod 906, thereby driving the threaded tube 907 to move. At the same time, the U-shaped block 904 can rotate along the third rotating shaft 903, and the ring 908 can rotate along the supporting rod 901, so as to realize the expansion and contraction of the scissor arm 102, thereby realizing the lifting and lowering of the cage 104. After reaching the specified height, the third motor 905 is stopped to ensure the stability of the lift.

[0065] When workers are working at high altitudes, when it is necessary to move the cage 104 horizontally, the first motor 207 is started, and the rotation of the first motor 207 drives the rotation of the first threaded rod 204, thereby driving the second moving block 206 and the first moving block 205 to move, and then driving the cage 104 to move horizontally. At the same time, when the second moving block 206 moves, the pull rope 304 can be pulled by the first spring 307 to move synchronously, and the counterweight plate 1003 can be pulled along the installation groove 1001 to move in the opposite direction of the horizontal movement of the cage 104, so that the counterweight operation can be performed, thereby avoiding the deviation of the center of gravity, which is safer and more reliable;

[0066] After the cage 104 moves horizontally, when the workers move to the two sides of the cage 104, they step on the fixed column 702, thereby driving the movable plate 701 and the push plate 703 to move downward through the fixed column 702, and the third spring 802 is compressed. At the same time, the push plate 703 is abutted against the top of the rotating plate 404, so that the rotating plate 404 can be pushed to rotate downward along the second rotating shaft 403, and the distance after the rotating plate 404 rotates is detected by the distance sensor 406. When the workers are closer to the two sides of the cage 104, the angle of rotation of the rotating plate 404 can be greater. At this time, the distance sensor 406 detects that the distance of the rotating plate 404 is closer. At this time, the second motor 401 can be started. The rotation of the second motor 401 drives the rotation of the first rotating shaft 302 and the conveying wheel 303, thereby driving the pull rope 304 for conveying. At the same time, the first spring 307 is compressed. At this time, the counterweight plate 1003 can be pulled by the pull rope 304 to continue to move for fine adjustment. Moreover, when the worker is closer to the two sides of the cage 104, the fine adjustment distance of the counterweight plate 1003 is larger, so that the counterweight effect of the cage 104 is better, safer and more reliable;

[0067] After the aerial work is completed, follow the reverse steps to lower the lift to the ground.

[0068] In summary: the beneficial effects of the present invention are specifically reflected in that it is convenient to move the cage 104 horizontally during high-altitude operations, which can improve the efficiency of high-altitude operations. At the same time, during the horizontal movement of the cage 104, the counterweight plate 1003 can be pulled along the installation groove 1001 to move in the opposite direction of the horizontal movement of the cage 104, and the counterweight operation can be performed, thereby avoiding the shift of the center of gravity. Moreover, the closer the workers are to the two sides of the cage 104, the greater the distance of fine-tuning of the counterweight plate 1003, thereby making the counterweight effect of the cage 104 better, safer and more reliable.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
