Description

Technical Field

[0001] The present invention relates to the technical field of cable installation equipment, and in particular to a cable retracting and releasing system and method. Background Art

[0002] Cable retraction is an essential process in cable line construction, emergency repair, cable testing and other situations where cables are needed. During the cable retraction process, the hoist is not only inconvenient to move, but also has a limited lifting range. Before lifting, it is necessary to manually adjust the hoist's load-bearing platform to a suitable height according to the center height of the cable drum. The steps for lifting the cable drum are cumbersome. When manually adjusting the load-bearing platform, the left and right load-bearing platforms are prone to rise / fall out of sync, causing the cable drum to overturn, posing a safety hazard.

[0003] During the cable retraction and deployment construction process, only manual labor can be used for operation, which is time-consuming and labor-intensive; the center axis, the center hole of the cable drum, and the contact position of the hoist are all overlapped on site, and the resistance at the joint is large, and the resistance to rotational movement is large. Retracting and deploying the cables is time-consuming and labor-intensive, which causes more economic costs and is not conducive to the rapid construction of retracting and deploying the cables. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a cable retracting and releasing system and method, which can realize the rapid retracting and releasing of the cable.

[0005] The invention also provides a method for retracting and releasing the cable.

[0006] A cable retracting and releasing system according to an embodiment of a first aspect of the present invention comprises:

[0007] Walking system;

[0008] A locking system, arranged on the walking system to limit the movement of the walking system;

[0009] A lifting system, arranged on the walking system, the lifting system having an up and down driving stroke;

[0010] The cable retracting and releasing system comprises a mounting frame and a supporting rotating sleeve, wherein the lifting system is connected to the mounting frame to drive the mounting frame to move up and down, and two supporting rotating sleeves are horizontally rotatably arranged on the mounting frame, and the two supporting rotating sleeves are arranged in parallel and spaced apart;

[0011] A control system is electrically connected to the lifting system.

[0012] A cable retracting and releasing system according to an embodiment of the present invention has at least the following beneficial effects:

[0013] 1. Before lifting the cable drum, push the two cable retracting and releasing systems to both ends of the cable drum. Due to the setting of the walking system, the cable retracting and releasing system can move as the cable release point changes.

[0014] 2. After the two cable retracting and releasing systems are pushed to both ends of the cable drum, the outer edges of both ends of the cable drum are respectively contacted with the two supporting rotating sleeves by pushing the two cable retracting and releasing systems, and the weight of the cable drum is borne by the supporting rotating sleeves. After the cable retracting and releasing systems are pushed into place, they are locked by the locking system to limit the movement of the walking system, ensuring that the walking system cannot move during subsequent actions, and the lifting preparation of the cable drum is completed.

[0015] 3. Control the lifting system through the control system to drive the mounting frame to rise, and the supporting rotating sleeve will rise accordingly, lifting the cable reel to a preset height for cable retracting and releasing. The purpose of setting up a control system is that in the process of lifting the cable reel, both ends of the cable reel need to be lifted synchronously, otherwise the two ends are prone to be at different heights, and there is a risk of the cable reel overturning. If manual adjustment is used, the two ends are prone to being out of sync, causing the cable reel to overturn, posing a safety hazard. The present application sets up a control system.

[0034] 1. Before lifting the cable drum, push the two cable retracting and releasing systems to both ends of the cable drum. Due to the setting of the walking system, the cable retracting and releasing system can move as the cable release point changes.

[0035] 2. After the two cable retracting and releasing systems are pushed to both ends of the cable drum, the outer edges of both ends of the cable drum are respectively contacted with the two supporting rotating sleeves by pushing the two cable retracting and releasing systems, and the weight of the cable drum is borne by the supporting rotating sleeves.

[0036] 3. Control the lifting system through the control system to drive the mounting frame to rise, and the supporting rotating sleeve will rise accordingly, lifting the cable reel to a preset height for cable retracting and releasing. The purpose of setting up a control system is that in the process of lifting the cable reel, both ends of the cable reel need to be lifted synchronously, otherwise the two ends are prone to be at different heights, and there is a risk of the cable reel overturning. If manual adjustment is used, the two ends are prone to being out of sync, causing the cable reel to overturn, posing a safety hazard. The present application sets up a control system.

[0037] 4. When releasing the cable, by driving the cable drum to rotate in the forward direction, the supporting rotating sleeve rotates with the cable drum.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0063] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0064] Reference Figure 1 and Figure 2 As shown, the present invention provides a cable retracting and releasing system, comprising:

[0065] Walking system 100;

[0066] A locking system 200 is provided on the traveling system 100 to limit the movement of the traveling system 100;

[0067] The lifting system 300 is arranged on the walking system 100, and the lifting system 300 has an up and down driving stroke;

[0068] The cable retracting system 400 includes a mounting frame 410 and a supporting rotating sleeve 420. The lifting system 300 is connected to the mounting frame 410 to drive the mounting frame 410 to move up and down. Two supporting rotating sleeves 420 are horizontally rotatably arranged on the mounting frame 410, and the two supporting rotating sleeves 420 are arranged in parallel and spaced apart.

[0069] Combination Figure 7 and Figure 8 As shown, before lifting the cable drum 800, two cable retracting and releasing systems are pushed to both ends of the cable drum 800. It can be understood that, due to the setting of the traveling system 100, the cable retracting and releasing system can move as the cable releasing point changes. Among them, the traveling system 100 is mainly composed of a bracket and a traveling wheel set arranged on the bracket, and its main function is to transfer the entire equipment.

[0070] After the two cable retracting and releasing systems are pushed to the two ends of the cable drum 800, the outer edges of the two ends of the cable drum 800 are respectively contacted with the two supporting rotating sleeves 420 by pushing the two cable retracting and releasing systems, and the weight of the cable drum 800 is borne by the supporting rotating sleeves 420. After the cable retracting and releasing systems are pushed into place, they are locked by the locking system 200 to limit the movement of the walking system 100, ensuring that the walking system 100 cannot move during subsequent actions, and the lifting preparation of the cable drum 800 is completed.

[0071] The lifting system 300 is controlled by the control system 900 to move, drive the mounting frame 410 to rise, and the supporting rotating sleeve 420 to rise accordingly, and lift the cable drum 800 to a preset height so as to retract and release the cable. The purpose of setting the control system 900 is that in the process of lifting the cable drum 800, it is necessary to make the two ends of the cable drum 800 rise synchronously, otherwise the two ends are prone to be at different heights, and the cable drum 800 is at risk of overturning. If manual adjustment is used, it is easy for the two ends to be out of sync, causing the cable drum 800 to overturn, posing a safety hazard. The present application sets the control system 900. As long as the corresponding control program is set, the control system 900 and the lifting system 300 are electrically connected. Through the control system 900, the two ends of the cable drum 800 can be raised and lowered at the same time, reducing the risk of overturning.

[0072] When releasing the cable, the cable drum 800 is driven to rotate forwardly, and the supporting rotating sleeve 420 rotates with the cable drum 800. Since the supporting rotating sleeve 420 is rotatably arranged on the mounting frame 410, it can be ensured that the cable drum 800 is subjected to little resistance during the rotation process, and it does not require too much driving force to ensure the rotation of the cable drum 800. During the forward rotation process of the cable drum 800, the cable on the cable drum 800 is released.

[0073] When the cable is collected, the cable drum 800 is driven to rotate in the opposite direction, and the supporting rotating sleeve 420 rotates with the cable drum 800. Since the supporting rotating sleeve 420 is rotatably arranged on the mounting frame 410, it can be ensured that the cable drum 800 is subjected to little resistance during the rotation process, and a large driving force is not required to ensure the rotation of the cable drum 800. During the reverse rotation process of the cable drum 800, the cable is rolled onto the cable drum 800.

[0074] After the cable is retracted and released, the control system 900 controls the lifting system 300 to move, driving the mounting frame 410 to descend, and the supporting rotating sleeve 420 to descend accordingly, so that the cable drum 800 descends to the ground.

[0075] The cable retracting and releasing system of the present invention is convenient to transfer during the process of retracting and releasing the cable from the cable drum, without the need for lifting equipment and a central axis. During the cable retracting process, since the driving force is provided by friction between the supporting rotating sleeve 420 and the cable drum 800, when the cable pulling force is too large, slippage will occur between the cable drum 800 and the supporting rotating sleeve 420, that is, although the supporting rotating sleeve 420 is rotating, the cable drum 800 will not rotate with it, thereby preventing the cable from being damaged by excessive pulling.

[0076] Combination Figure 5 As shown, it also includes a rotating mounting seat 500, and the mounting frame 410 includes a sliding support rod 411, the sliding support rod 411 is horizontally arranged, and the supporting rotating sleeve 420 is connected through the rotating mounting seat 500 and the sliding support rod 411. The rotating mounting seat 500 can adjust the installation position along the axial direction of the sliding support rod 411 to adjust the distance between the two supporting rotating sleeves 420.

[0077] It is understandable that cable drums 800 of different specifications have different drum diameters. When laying cables on cable drums 800 of different specifications, the distance between the two supporting rotating sleeves 420 needs to be adaptively adjusted to ensure that the appropriate distance can meet the load-bearing requirements of the cable drum 800. It is understandable that the sliding support rod 411 is connected to the lifting system 300 through a connector and can be lifted and lowered under the action of the lifting system 300. When the distance between the two supporting rotating sleeves 420 is adaptively adjusted, the supporting rotating sleeves 420 adjust the installation position along the axial direction of the sliding support rod 411 by rotating the mounting seat 500, and the distance between the two supporting rotating sleeves 420 is adjusted by adjusting the position of the rotating mounting seat 500, thereby adapting to cable drums 800 of different outer diameters.

[0078] Combination Figure 5 As shown, it can be understood that the rotating mounting seat 500 includes a mounting shaft 510, a mounting sleeve 520 and a positioning piece 530, which supports the rotating sleeve 420 to be rotatably mounted on the mounting shaft 510, the mounting shaft 510 and the mounting sleeve 520 are connected, the mounting sleeve 520 is sleeved on the sliding support rod 411, and the mounting sleeve 520 can move along the sliding support rod 411 and be fixed in position by the positioning piece 530.

[0079] In this embodiment, the support rotating sleeve 420 is rotatably mounted on the mounting shaft 510. Specifically, the support rotating sleeve 420 is rotatably mounted on the mounting shaft 510 through a bearing, so as to ensure that the support rotating sleeve 420 rotates smoothly on the mounting shaft 510 and is subjected to little friction during rotation. The mounting sleeve 520 is sleeved on the sliding support rod 411 and can move to any position along the sliding support rod 411 to achieve the purpose of adjusting the distance between the two support rotating sleeves 420. After the position is adjusted, the position of the support rotating sleeve 420 is fixed by the positioning member 530 to prevent the support rotating sleeve 420 from moving during the process of carrying the cable drum 800.

[0080] refer to Figure 2 As shown, the sliding support rod 411 is provided with a plurality of positioning holes 4111, and the positioning holes 4111 are arranged along the axial direction of the sliding support rod 411. The mounting sleeve 520 is sleeved on the sliding support rod 411 and can slide along the sliding support rod 411. The mounting sleeve 520 is provided with a fixing hole, and the positioning piece 530 can pass through the positioning hole 4111 and the fixing hole to fix the mounting sleeve 520.

[0081] It is understandable that, during the process of the installation sleeve 520 moving along the sliding support rod 411, after moving to the appropriate position, it is ensured that the fixing hole on the installation sleeve 520 corresponds to the positioning hole 4111, and after the positioning member 530 passes through the fixing hole and the positioning hole 4111 in turn, the positioning member 530 is locked and fixed, thereby fixing the installation sleeve 520 on the sliding support rod 411. Determine the distance between the two supporting rotating sleeves 420. Among them, the positioning member 530 is specifically a positioning pin or a positioning bolt. When it is necessary to explain, the distance between the two supporting rotating sleeves 420 can allow a larger error, as long as it can carry the cable drum 800 of the corresponding specifications, therefore, the distance between the positioning holes 4111 can be within this error range.

[0082] refer to Figure 3 and Figure 4 As shown, a driving device 600 is also included, and the driving device 600 is transmission-connected to the supporting rotating sleeve 420 to drive the supporting rotating sleeve 420 to rotate forward and reverse.

[0083] In this embodiment, the driving device 600 drives the supporting rotating sleeve 420 to rotate. Due to the friction between the supporting rotating sleeve 420 and the cable drum 800, the supporting rotating sleeve 420 rotates, which drives the cable drum 800 to rotate.

[0084] Combination Figure 8 As shown, when releasing the cable, the driving device 600 drives the supporting rotating sleeve 420 to rotate forward, providing power for the previous section of the cable conveyor / traction device when releasing the cable. When collecting the cable, the driving device 600 drives the supporting rotating sleeve 420 to rotate in the opposite direction, driving the cable drum 800 to rotate in the opposite direction, so that the cable drum 800 can reel the cable.

[0085] During the cable winding process, since the driving force is provided by friction between the supporting rotating sleeve 420 and the cable drum 800, when the cable pulling force is too large, slippage will occur between the cable drum 800 and the supporting rotating sleeve 420, that is, although the supporting rotating sleeve 420 is rotating, the cable drum 800 will not rotate with it, thereby avoiding the cable from being damaged by excessive pulling.

[0086] Reference Figure 1 and Figure 2 It can be understood that the lifting system 300 includes a lifting rail 310, a load-bearing lifting platform 320 and a lifting power device 330. The lifting rail 310 is installed on the walking system 100, and the load-bearing lifting platform 320 is installed on the lifting rail 310 and can perform lifting movements along the lifting rail 310. The lifting power device 330 and the load-bearing lifting platform 320 are connected by transmission to drive the load-bearing lifting platform 320 to move up and down, and the mounting frame 410 is installed on the load-bearing lifting platform 320.

[0087] In this embodiment, the mounting frame 410 is mounted on the load-bearing lifting platform 320. When the height position of the mounting frame 410 needs to be adjusted, the load-bearing lifting platform 320 is driven to move up and down on the lifting rail 310 by the lifting power device 330, thereby changing the position of the mounting frame 410. It can be understood that the track height travel of the lifting rail 310 can be set so that the mounting frame 410 can move to any height in the track, which can meet the needs of cable reels 800 with various outer diameters.

[0088] Reference Figure 1 and Figure 2 As shown, it is understood that the lifting power device 330 is a hydraulic lifting system. It is understood that the hydraulic lifting system includes components such as a hydraulic pump and a hydraulic cylinder. The hydraulic lifting system can provide stable power for the lifting action. It is understood that the lifting power device 330 can also be other power equipment, such as an electric drive device.

[0089] Reference Figure 6 As shown, it can be understood that a locking system 700 is also included, and the locking system 700 can lock and fix the load-bearing lifting platform 320.

[0090] The hydraulic lifting system itself has the function of being stationary at a certain position, but from a safety perspective, when the equipment is working, workers are working near it, and the hydraulic lifting system may leak, release pressure or other possible hydraulic failures, which may pose a safety hazard. This embodiment further provides a locking system 700 to provide double locking protection to ensure safety.

[0091] Reference Figure 6 As shown, it can be understood that the locking system 700 includes a locking assembly 710 and a control member 720. A plurality of locking holes 321 are provided on the load-bearing lifting platform 320. The locking holes 321 are arranged in a vertical direction. The locking assembly 710 is provided with a locking tooth 7121. The locking assembly 710 has a locking position and a free position. In the locking position, the locking tooth 7121 is inserted into at least one locking hole 321 to lock and fix the load-bearing lifting platform 320. In the free position, the locking tooth 7121 is disengaged from the locking hole 321 to cancel the lock on the load-bearing lifting platform 320.

[0092] In this embodiment, when the load-bearing lifting platform 320 rises to a certain position that meets the height of the cable reel 800 for retracting and releasing cables, the locking assembly 710 moves to the locking position, so that at least one locking tooth 7121 is inserted into a locking hole 321. The load-bearing lifting platform 320 is locked and fixed through the limiting effect of the locking tooth 7121. Even when the hydraulic system fails, the locking tooth 7121 can prevent the load-bearing lifting platform 320 from sliding down and causing the cable reel 800 to fall, thereby avoiding a threat to the safety of surrounding personnel.

[0093] When the cable is retracted and the cable reel 800 needs to be lowered, the locking assembly 710 is adjusted from the locking position to the free position, so that the locking tooth 7121 is disengaged from the locking hole 321, thereby canceling the lock of the locking tooth 7121 on the load-bearing lifting platform 320, so that the load-bearing lifting platform 320 can move downward under the control of the lifting power device 330, thereby completing the lowering of the cable reel 800.

[0094] Reference Figure 6 As shown, it can be understood that the locking assembly 710 includes a mounting seat 711, a rotating block 712, a rotating shaft 713 and an elastic member 714. The mounting seat 711 is installed on the lifting rail 310. The rotating block 712 is rotatably connected to the mounting seat 711 through the rotating shaft 713. A locking tooth 7121 is provided on the rotating block 712. The locking tooth 7121 is a one-way latch tooth. The one-way latch tooth can prevent the load-bearing lifting platform 320 from moving downward. The elastic member 714 is connected to the rotating block 712 to push the rotating block 712 to rotate around the rotating shaft 713. When the elastic member 714 is in a released state, the one-way latch tooth is latched in the locking hole 321. When the elastic member 714 is in a compressed state, the one-way latch tooth is disengaged from the locking hole 321. The control member 720 is connected to the rotating block 712 and can drive the rotating block 712 to rotate around the rotating shaft 713.

[0095] In this embodiment, during the ascending process of the load-bearing lifting platform 320, the rotating block 712, under the action of the elastic member 714, will push the one-way latch tooth to be stuck in a corresponding locking hole 321. Since the one-way latch tooth is stuck in the locking hole 321, the one-way latch tooth will only limit the downward movement of the load-bearing lifting platform 320, and will not prevent the load-bearing lifting platform 320 from moving upward. Therefore, the load-bearing lifting platform 320 can move upward normally, and the one-way latch tooth will be stuck in the next locking hole 321.

[0096] When the load-carrying lifting platform 320 needs to move downward, the control member 720 drives the rotating block 712 to rotate around the rotating shaft 713, so that the one-way latching tooth disengages from the locking hole 321, and the one-way latching tooth cancels the restrictive effect on the load-carrying lifting platform 320, so that the load-carrying lifting platform 320 can be normally lowered. At this time, when the elastic member 714 is in a compressed state, as long as the control member 720 cancels the force on the rotating block 712 again, the elastic member 714 can be restored from the compressed state to the released state again, so that the one-way latching tooth presses against the locking hole 321.

[0097] In this embodiment, the elastic member 714 includes a compression spring and a guide column. The guide column is vertically slidably mounted on the mounting seat 711. The upper end of the guide column is connected to the rotating block 712. The compression spring is sleeved on the guide column. The upper end of the compression spring is in contact with the rotating block 712, and the lower end is in contact with the mounting seat 711. When the compression spring is stretched, it pushes the rotating block 712 to rotate, so that the one-way latch tooth is pressed against the locking hole 321. When the control member 720 applies a force to the rotating block 712, so that the rotating block 712 rotates in the opposite direction, the one-way latch tooth is disengaged from the locking hole 321, and the compression spring is compressed to store energy. The control member 720 removes the force on the rotating block 712, and the compression spring returns to the released state again, so that the one-way latch tooth is pressed against the locking hole 321.

[0098] Reference Figure 6 As shown, it can be understood that the control member 720 includes a connecting portion and a pedal portion, the control member 720 is vertically arranged, the upper end of the control member 720 is connected to the rotating block 712 through the connecting portion, and the lower end of the control member 720 is provided with a pedal portion.

[0099] In this embodiment, the control member 720 is a rod-shaped member, the upper end of the control member 720 is connected to the rotating block 712, and the lower end is bent into a pedal portion for stepping. When the operator steps on the pedal portion and presses down, the rotating block 712 can be driven to rotate, so that the one-way latch tooth disengages from the locking hole 321, and the compression spring is compressed to store energy. When the force on the pedal is removed, the compression spring returns to the released state again, so that the one-way latch tooth presses toward the locking hole 321. The control method of the control member 720 has the characteristics of simple structure and convenient operation.

[0100] Reference Figure 1 and Figure 3As shown, it can be understood that the walking system 100 includes a support and a walking wheel group, the walking wheel group is installed at the bottom of the support, the locking system 200 includes a mobile chassis 210 and a lifting mechanism 220, the mobile chassis 210 is connected to the support, the mobile chassis 210 has an up and down lifting stroke, the mobile chassis 210 has a first position and a second position, the lifting mechanism 220 and the mobile chassis 210 are transmission-connected to control the movement of the mobile chassis 210 between the first position and the second position, in the first position, the mobile chassis 210 is supported on the ground, and in the second position, the mobile chassis 210 rises to be separated from the ground.

[0101] When the equipment needs to be transferred, the lifting mechanism 220 drives the mobile chassis 210 to rise to the second position. At this time, the mobile chassis 210 is separated from the ground, and only the running wheel group is in contact with the ground. The running wheel group can continue to rotate to drive the entire equipment to transfer.

[0102] Reference Figure 7 and Figure 8 As shown, it can be understood that the lifting mechanism 220 includes a jack 221 and a control rocker arm 222 , the mobile chassis 210 is connected to the lifting shaft of the jack 221 , and the control rocker arm 222 is connected to the jack 221 to control the extension and retraction of the lifting shaft of the jack 221 .

[0103] In this embodiment, by controlling the swing rod 222 to swing up and down, the lifting shaft of the jack 221 is extended and retracted, so that the mobile chassis 210 moves up and down, thereby controlling the mobile chassis 210 to move between the first position and the second position. The above control method has the characteristics of simple structure and convenient operation.

[0104] The present invention also discloses a method for retracting and releasing a cable, comprising the above-mentioned cable retracting and releasing system 400, and retracting and releasing the cable through the following steps:

[0105] Step S1: Push two cable retracting and releasing systems 400 to both ends of the cable drum 800, and push the two cable retracting and releasing systems 400 so that the outer edges of both ends of the cable drum 800 are in contact with two supporting rotating sleeves 420 respectively;

[0106] Step S2: Locking the locking system 200 to restrict the movement of the traveling system 100;

[0107] Step S3: The control system 900 controls the lifting system 300 to move, driving the mounting frame 410 to rise synchronously, and the supporting rotating sleeve 420 to rise accordingly, thereby lifting the cable drum 800 to a preset height;

[0108] Step S4: When releasing the cable, the cable drum 800 is driven to rotate forwardly, and the supporting rotating sleeve 420 rotates along with the cable drum 800. During the forward rotation of the cable drum 800, the cable on the cable drum 800 is released;

[0109] When the cable is collected, the cable drum 800 is driven to rotate in the reverse direction, and the supporting rotating sleeve 420 rotates along with the cable drum 800. During the reverse rotation of the cable drum 800, the cable is collected onto the cable drum 800.

[0110] Step S5: After the cable is retracted and released, the control system 900 controls the lifting system 300 to drive the mounting frame 410 to descend synchronously, thereby driving the cable drum 800 to descend to the ground.

[0111] The cable retracting and releasing system of the present invention is convenient to transfer during the process of retracting and releasing the cable on the cable drum, and does not require the use of lifting equipment and a central axis, thereby freeing up manpower and realizing automatic retracting and releasing of the cable.

[0112] According to some embodiments of the present invention, in step S4, the driving device 600 drives the supporting rotating sleeve 420 to rotate, and the supporting rotating sleeve 420 drives the cable reel 800 to rotate to retract and release the cable.

[0113] According to some embodiments of the present invention, in step S3, after the cable reel 800 is raised to a preset position, the load-bearing lifting platform 320 is locked and fixed by the locking system 700; in step S5, after the cable reel 800 completes cable retraction and release, the locking system 700 cancels the locking and fixing of the load-bearing lifting platform 320, and then controls the lifting system 300 through the control system 900 to drive the mounting frame 410 to descend synchronously, thereby driving the cable reel 800 to descend to the ground.

[0114] During the cable winding process, since the driving force is provided by friction between the supporting rotating sleeve 420 and the cable drum 800, when the cable pulling force is too large, slippage will occur between the cable drum 800 and the supporting rotating sleeve 420, that is, although the supporting rotating sleeve 420 is rotating, the cable drum 800 will not rotate with it, thereby avoiding the cable from being damaged by excessive pulling.

[0115] This embodiment further provides a locking system 700, through a locking step, so that after the load-bearing lifting platform 320 is raised to a preset position, the load-bearing lifting platform 320 is locked and fixed by the locking system 700, so that even when the hydraulic system fails, the load-bearing lifting platform 320 can still be prevented from falling. Double locking protection can be performed to ensure safety.

[0116] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
