Each group of trolleys includes two load-bearing wheel sets suspended on the load-bearing cables and a lifting wheel set commonly hinged below the two load-bearing wheel sets. The two load-bearing wheel sets are arranged at intervals along the length direction of the load-bearing cables. A hanging member moving in the vertical direction is provided below the lifting wheel set, and multiple lifting cables are connected between the lifting wheel set and the hanging member. One end of each lifting cable is commonly connected to a first lifting winch anchored on the ground. By adopting the technical solution of the present invention, it can effectively solve the problems in the current cable hoisting and towing system that two sets of separate lifting cables are required to control the height of the hanging member for two adjacent groups of trolleys on the same side, resulting in a relatively heavy total weight of the cable crane system, and the routing methods of the trolleys and the hanging member still need to be optimized.

Description

Technical Field

[0001] The invention belongs to the technical field of cable hoisting for bridge construction, and particularly relates to an adaptive hoisting system for a cable hoist. Background Art

[0002] A cable hoist is a commonly used hoisting equipment for the construction of the upper structure of a bridge, which consists of a load-bearing system, a traction system, a hoisting system, a tower, etc. With the development of China's economy and social needs, there is an urgent need for large-span bridges with larger spans and stronger load-bearing capacities in China. At the same time, higher requirements are put forward for the hoisting span and hoisting capacity of the cable hoist. The steel wire rope of the cable hoist traction system passes through the trolley and the turning wheels anchored at both ends multiple times back and forth to form a closed loop. At present, the maximum closed length of the steel wire rope used in the cable hoist traction system is nearly 20,000 meters. It is very difficult to manufacture and transport a single ten-thousand-meter-level traction steel wire rope. Often, multiple steel wire ropes need to be connected in series. However, the smoothness of the interface of the connected steel wire ropes is poor and the safety risk increases. With the increase of the hoisting span and hoisting capacity of the cable hoist, it is particularly important to optimize the routing method of the cable hoist traction system under the limitation of the maximum processing length of the steel wire rope.

[0003] For example, the Chinese patent discloses a bidirectional traction adaptive racehorse system for a cable hoisting system (patent publication number: CN110386559A). The triangular connecting beam connects two groups of weighing frame plates into a whole through a connecting shaft, which can adapt to the attitude change of the load-bearing system, meet the large-angle climbing construction of the racehorse system, and the traction wheels of the hierarchical traction system are vertically arranged, so that the sufficient number of traction wheels can be ensured within a limited space, which can meet the traction requirements of heavy loads. At the same time, the traction small guide wheels installed on the upper part of the traction frame can ensure that the load-bearing cable and the traction cable are layered and orderly during the traction process and do not interfere with each other.

[0004] Although the above technical solution solves the problems of mutual interference between the load-bearing cable and the traction cable in the current racehorse system, and the inflexible climbing and limited moving range caused by the fixed structure of the trolley, it does not improve the weight problem of the cable hoist system. During the actual construction process, usually two sets of trolleys are arranged on the same set of load-bearing cables, and a total of four sets of trolleys are arranged on both sides along the width direction of the bridge and cooperate with the lifting parts to lift the goods together. Among them, the two trolleys on the same set of load-bearing cables respectively correspond to two hoisting winches, and the two hoisting winches need to use two separate sets of independent hoisting cables to control the height of the lifting parts on each trolley respectively. This not only makes the installation complex, but also greatly increases the total weight of the cable hoist system. During the construction of large or extra-large bridges, it is also necessary to optimize the routing method of the cable hoist traction system and reduce its total weight. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a cable crane adaptive lifting system to solve the problems in the current cable hoisting and traction system, where two sets of adjacent trolleys on the same side need to use two sets of separate hoisting ropes to control the height of the suspended load respectively, resulting in a relatively heavy total weight of the cable crane system, and the routing methods of the trolleys and the suspended load still need to be optimized.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A cable crane adaptive lifting system includes multiple load-bearing ropes, two sets of trolleys arranged along the length direction of the load-bearing ropes and suspended on their surfaces, and a traction rope for towing the two sets of trolleys. Each set of trolleys includes two load-bearing wheel groups suspended on the load-bearing rope and a hoisting wheel group commonly hinged below the two load-bearing wheel groups. The two load-bearing wheel groups are arranged at intervals along the length direction of the load-bearing rope. A suspended load moving in the vertical direction is provided below the hoisting wheel group, and multiple hoisting ropes are connected between the hoisting wheel group and the suspended load. Among them, one end of each hoisting rope is commonly connected to a first hoisting winch anchored on the ground, and the other end simultaneously bypasses the hoisting wheels of the two sets of trolleys and the suspended load, and then is connected to a second hoisting winch anchored on the ground;

[0008] Each hoisting wheel group includes a connecting housing simultaneously hinged to the two load-bearing wheel groups and multiple groups of hoisting wheels rotatably connected to its surface. Among them, each group of hoisting wheels is arranged at intervals along the length direction of the load-bearing rope and corresponds to each hoisting rope, and each hoisting rope bypasses the corresponding hoisting wheel. A first braking unit for restricting the movement of each hoisting rope is provided on the connecting housing, and the first braking unit is arranged on the side close to the adjacent trolley. The first braking unit includes multiple first brake blocks and a hydraulic telescopic cylinder for driving each first brake block to move. The hydraulic telescopic cylinder is fixedly installed on the connecting housing, and each first brake block is arranged at the working end of the corresponding hydraulic telescopic cylinder. When the working end of the hydraulic telescopic cylinder moves a certain distance towards the hoisting wheel close to the adjacent trolley, each first brake block abuts against the corresponding hoisting rope and restricts the movement of the hoisting rope.

[0009] Furthermore, a controller for controlling the movement of the hydraulic telescopic cylinder is provided on the surface of each connecting housing. The controller is electrically connected to a power supply for supplying power and a wireless transmission device for remotely transmitting information. The power supply is also electrically connected to a power generation component. The power generation component is arranged on the connecting housing and provides power through the rotation of the corresponding hoisting wheel group, thereby generating current to charge the power supply.

[0010] Furthermore, on one side surface of each of the connecting shells close to the adjacent sports cars, a second braking unit is provided. The second braking unit includes a support shell arranged on one side of the connecting shell, and a plurality of second braking blocks and a plurality of third braking blocks which are movably arranged on the support shell and correspond to each hoisting cable. Among them, each second braking block and the corresponding third braking block are respectively fixedly arranged at intervals up and down on both sides of the corresponding hoisting cable. A plurality of movable blocks rotating in a vertical plane are also rotatably connected to the support shell, and each two second braking blocks and third braking blocks arranged at intervals up and down are fixed on a corresponding movable block. One end of each movable block is connected to the working end of a hydraulic telescopic cylinder by a transmission rod. The transmission rod is rotatably arranged on the surface of the support shell. When the working end of the hydraulic telescopic cylinder moves towards the corresponding hoisting wheel, the movable block is synchronously driven to rotate through the transmission rod, so that the surfaces of the second braking block and the third braking block simultaneously abut against the corresponding hoisting cable and restrict its movement.

[0011] Furthermore, on one side surface of each of the first braking blocks, second braking blocks and third braking blocks close to the hoisting cable, a groove is provided, and a friction plate is arranged in the groove.

[0012] Furthermore, a plurality of displacement sensors corresponding to the hoisting cables one by one are arranged on the surface of each connecting shell. The working end of each displacement sensor faces the surface of the corresponding hoisting cable and is used for detecting the displacement of the hoisting cable between the first braking block and the third braking block. Each displacement sensor is electrically connected to the corresponding controller.

[0013] Furthermore, distance sensors are arranged on the surface of each connecting shell and the surface of the hanging member, and each distance sensor is electrically connected to the corresponding controller.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention optimizes the routing mode of the load-bearing cable by providing a first braking unit on each sports car to restrict the hoisting cable. Compared with the existing cable crane system, the weight of the hoisting cables corresponding to at least two groups of sports cars can be reduced. Through the arrangement of the first hoisting winch, the second hoisting winch and the first braking unit, the adjacent two sports cars on the same side can use the same group of hoisting cables to control the heights of two hanging members respectively, reducing the total weight of the traditional cable crane system, and being applicable to cable crane systems with large spans and extra-large spans;

[0016] 2. By setting a second braking unit on each group of trolleys, the braking effect on each load-bearing cable can be further improved, and the precise control of the height of each hanging piece can be enhanced. Even when the trolley climbs along the load-bearing cable, the height of each hanging piece can be maintained at the same horizontal level through the control of the controller, ensuring the stability of the hoisted goods and the safety during bridge construction.

[0017] Other advantages, objectives, and features of the present invention will be described in the subsequent specification, and to some extent, they are obvious to those skilled in the art, or those skilled in the art can obtain teachings from the practice of the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the following specification. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] As Figures 1 to 7 shown

[0029] A cable crane adaptive lifting system includes multiple load-bearing cables 1, two sets of carriages 2 arranged along the length direction of the load-bearing cables 1 and suspended on the surface of each load-bearing cable 1, and a towing cable 3 for towing the two sets of carriages 2. One side of each set of carriages 2 facing the two ends of the bridge is connected to the corresponding towing winch (the towing winch is arranged at one end of the bridge and is not shown in the figure). The two sets of carriages 2 are linked by an auxiliary towing cable 14. Each set of carriages 2 includes two load-bearing wheel sets 4 suspended on the load-bearing cable 1 and a lifting wheel set 5 commonly hinged below the two load-bearing wheel sets 4. The two load-bearing wheel sets 4 are arranged at intervals along the length direction of the load-bearing cable 1. A lifting member 6 moving in the vertical direction is provided below the lifting wheel set 5, and three lifting cables 7 are connected between the lifting wheel set 5 and the lifting member 6. Among them, one end of each lifting cable 7 is commonly connected to a first lifting winch 8 anchored on the ground, and the other end simultaneously bypasses the lifting wheel sets 5 on the two sets of carriages 2 and the lifting member 6, and then is connected to a second lifting winch 9 anchored on the ground; the first lifting winch 8 and the second lifting winch 9 are respectively arranged on the riverbanks at the two ends of the bridge (specifically combined with Figure 3 shown), so, one end of the three lifting cables 7 is wound by the first lifting winch 8, and the other end passes through the two sets of carriages 2 on the same side and cooperates with them, and then is wound on the working end of the second lifting winch 9;

[0030] Each lifting wheel set 5 includes a connecting housing 501 simultaneously hinged to the two load-bearing wheel sets 4 and multiple groups of lifting wheels 502 rotatably connected to its surface. Among them, each group of lifting wheels 502 is arranged at intervals along the length direction of the load-bearing cable 1 and corresponds to each lifting cable 7, and each lifting cable 7 bypasses the corresponding lifting wheel 502 (the winding method of the lifting cable 7 and the multiple lifting wheels 502 is the prior art, and only a simple winding method is shown in the figure of the present invention for easy explanation and illustration). A first braking unit 10 for restricting the movement of each lifting cable 7 is provided on each connecting housing 501, and the first braking unit 10 is arranged on the side close to the adjacent carriage 2. The first braking unit 10 includes three first brake blocks 1001 and a hydraulic telescopic cylinder 1002 for driving each first brake block 1001 to move. The hydraulic telescopic cylinder 1002 is obliquely inserted into the connecting housing 501 and is fixedly connected to each other by bolts and nuts. Each first brake block 1001 is arranged at the working end of the corresponding hydraulic telescopic cylinder 1002, and when the working end of the hydraulic telescopic cylinder 1002 moves a certain distance towards the direction of the corresponding lifting wheel 502 close to the adjacent carriage 2, each first brake block 1001 abuts against the corresponding lifting cable 7 and restricts the movement of the lifting cable 7.

[0031] Combined with Figure 3As shown in the figure, the cable crane traction system of the present invention consists of four sets of carriages 2. Only two sets of carriages 2 on the same side are shown in the figure (the same side refers to two sets of carriages 2 suspended on the same load-bearing cable 1, with the same meaning in the context). When it is necessary to control the height of the hanging member 6 on a set of carriages 2 on the left side (combined with Figure 2 shown, the carriage 2 on the left side in this figure), first, control the working ends of each hydraulic telescopic cylinder 1002 on this carriage 2 to extend, so that the surfaces of the corresponding first brake blocks 1001 are all in contact with the corresponding hoisting cable 7, and jointly clamp the hoisting cable 7 with the corresponding hoisting wheel 502 to restrict the movement of the hoisting cable 7. For the convenience of explanation, the position where the first brake block 1001 and the hoisting wheel 502 jointly clamp the hoisting cable 7 is called the adjustable anchor head, while the hoisting cable 7 between the adjustable anchor head and the first hoisting winch 8 can move (which can be combined with Figure 7 shown). At this time, the height of this hanging member 6 can be controlled by controlling the first hoisting winch 8 to wind and unwind the hoisting cable 7, without affecting the height of the hanging member 6 on the other set of carriages 2; similarly, the other set of carriages 2 on the same side as the above-mentioned carriage 2 can also repeat the above steps, and the movement of the corresponding hoisting cable 7 can be restricted by controlling the first brake block 1001, so that the height adjustment of the hanging member 6 corresponding to this carriage 2 can be realized by controlling the second hoisting winch 9. The height adjustment mechanisms of the two hanging members 6 are independent of each other and do not affect each other, and the purpose of controlling the heights of the hanging members 6 on the two sets of carriages 2 by the first hoisting winch 8 and the second hoisting winch 9 respectively can be achieved; among them, combined with Figure 2 and Figure 7 shown, by adjusting the length of the auxiliary traction cable 14 between two adjacent sets of carriages 2, the distance between two adjacent sets of carriages 2 can be indirectly adjusted (a winch for winding the auxiliary traction cable or components such as a hydraulic telescopic cylinder can be installed on each carriage, which can be achieved by those skilled in the art and will not be elaborated here), so as to realize the hoisting of different-length hoisting units and improve the applicable range of the present invention to a certain extent.

[0032] When it is necessary to lower or raise the hanging members 6 on each set of carriages 2 simultaneously, control each first brake block 1001 to no longer contact the hoisting cable 7. At this time, the synchronous adjustment of the heights of the two hanging members 6 can be achieved by only controlling the first hoisting winch 8 to wind and unwind the hoisting cable 7, while the second hoisting winch 9 does not operate. Of course, it is also possible to only control the second hoisting winch 9 to wind and unwind, while the first hoisting winch 8 does not operate. In addition, the first hoisting winch 8 and the second hoisting winch 9 can also be synchronously controlled to wind and unwind at the same speed, so that the synchronous adjustment of the horizontal heights of the two hanging members 6 at twice the speed can be achieved;

[0033] When the two groups of trolleys 2 move driven by the towing cable 3, the height of the suspended load 6 can be maintained by controlling the first hoisting winch 8 and the second hoisting winch to wind and unwind the hoisting cable 7, without affecting the normal operation of the trolley 2. And when the trolley 2 approaches one end of the bridge driven by the towing cable 3, since the height of the cable crane towing system gradually decreases from both ends to the middle of the bridge (due to the self-weight of the cable crane towing system and the load during hoisting), therefore, when the trolley 2 approaches both ends of the bridge, it will be in a climbing state. At this time, there will be a height difference between the two groups of trolleys 2 on the same side. Of course, the suspended load 6 will also have a height difference. To solve the height difference between the two suspended loads 6, the winding and unwinding speeds of the first hoisting winch 8 and the second hoisting winch 9 can be controlled to be at different rotational speeds. Through the speed difference between the two, the height of each suspended load 6 can be adjusted. When the heights of the suspended loads 6 are on the same horizontal plane, then control the winding and unwinding speeds of the first hoisting winch 8 and the second hoisting winch 9 to be the same again, which can also effectively solve the adjustment of the height of the suspended load 6 when the trolley 2 is in the climbing state. Compared with the traditional cable crane towing system, a set of hoisting cables 7 on two trolleys 2 on the same side is reduced, greatly reducing the total weight of the cable crane towing system and improving the stability of the cable crane towing system under large-span and extra-large-span conditions. And compared with the adjustment of the height of the suspended load 6 in the traditional cable crane towing system, the operation of the present invention is simple and reliable.

[0034] In this embodiment, a controller for controlling the movement of the hydraulic telescopic cylinder 1002 is provided on the surface of each connection housing 501. The controller is electrically connected to a power supply 16 for supplying power and a wireless transmission device for remotely transmitting information (the wireless transmission device can adopt wireless transmission technologies such as 5G, Wi-Fi, etc.). The power supply 16 is also electrically connected to a power generation assembly 15. The power generation assembly 15 is fixed on the surface of the connection housing 501 by bolts and provides power through the rotation of the corresponding hoisting wheel set 5, thereby generating current and charging the power supply 16. Of course, the power generation assembly 15 can also be arranged on the load-bearing wheel set 4 and provide power through the rotation of the load-bearing wheel set 4 to charge the power supply 16.

[0035] Among them, the power generation assembly 15 includes a rotor, a housing with a magnetic field, and a coil. The rotor is power-connected to one of the wheels in the hoisting wheel set 5 (combined Figure 6As shown, when the hoisting wheel set 5 moves, it will drive the rotor to rotate. When the rotor rotates in the housing with a magnetic field, according to Faraday's law of electromagnetic induction, an induced electromotive force will be generated in the coil and charge the power supply 16. Therefore, this technical principle can be realized by those skilled in the art, and the corresponding equipment installation and implementation process will not be elaborated here; when each set of carriages 2 moves along the length direction of the hoisting cable 7, each load-bearing wheel on the load-bearing wheel set 4 will rotate. Of course, the traction wheel will also rotate. When adjusting the height of each lifting member 6, the other hoisting wheels 502 on each set of carriages 2 except those corresponding to the first brake block 1001 will also rotate (this is in the case of an adjustable anchor head). The rotating load-bearing wheels and hoisting wheels 502 can generate current through electromagnetic induction and charge the power supply 16 to ensure the normal operation of the power supply 16, the controller, the hydraulic telescopic cylinder 1002, and the wireless transmission device. Moreover, when the carriage 2 or the lifting member 6 moves, it will drive the power generation assembly 15 and continuously charge the power supply 16 through electromagnetic induction, reducing the weight of the separate power supply lines from both ends of the bridge to each set of carriages 2, eliminating the need to additionally install power supply lines, simplifying the cableway hoist traction system circuit, and with the setting of the power generation assembly 15, there is no need to worry about the power supply 16 running out of power.

[0036] In this embodiment, a second braking unit 11 is provided on the surface of each connecting housing 501 close to the adjacent sports car 2. The second braking unit 11 includes a support housing 1104 provided on one side of the connecting housing 501, and a plurality of second brake blocks 1101 and a plurality of third brake blocks 1102 movably provided on the support housing 1104. Each hoisting cable 7 corresponds to one second brake block 1101 and one third brake block 1102. Among them, each second brake block 1101 and the corresponding third brake block 1102 are respectively fixedly arranged at intervals up and down on both sides of the corresponding hoisting cable 7 (each third brake block 1102 and the corresponding second brake block 1101 are arranged at intervals left and right in the horizontal plane). A plurality of movable blocks 1103 that rotate in the vertical plane are also rotatably connected to the support housing 1104. Every two movable blocks 1103 correspond to one hoisting cable 7, and every two second brake blocks 1101 and third brake blocks 1102 arranged at intervals up and down are fixed between the corresponding two movable blocks 1103. One end of each movable block 1103 is connected to the working end of a hydraulic telescopic cylinder 1002 by a transmission rod 1105. The transmission rod 1105 is rotatably arranged on the surface of the support housing 1104. One end of the transmission rod 1105 is hinged to the working end of the corresponding hydraulic telescopic cylinder 1002, and the other end is hinged to the movable block 1103. When the working end of the hydraulic telescopic cylinder 1002 moves towards the corresponding hoisting wheel 502, the movable block 1103, the second brake block 1101 and the third brake block 1102 are synchronously driven by the transmission rod 1105 to deflect by a certain angle, so that the surfaces of the second brake block 1101 and the third brake block 1102 simultaneously abut against the corresponding hoisting cable 7 and restrict its movement.

[0037] As shown in the figure, when it is necessary to adjust the height of the suspension piece 6 under one of the sports cars 2, each hydraulic telescopic cylinder 1002 on this sports car 2 is controlled to start working. The working end of the hydraulic telescopic cylinder 1002 extends and drives the first brake block 1001 to move towards the corresponding hoisting wheel 502. At the same time, during the extension of the working end of the hydraulic telescopic cylinder 1002, it will rotate through the transmission rod 1105. While the transmission rod 1105 rotates, it will drive the corresponding movable block 1103 to deflect (as shown in the figure, the moment length between the rotation center of the transmission rod 1105 and the hydraulic telescopic cylinder 1002 is greater than the moment length to the movable block 1103, forming a labor-saving lever that can magnify and increase the moment of the hydraulic telescopic cylinder 1002). After the movable block 1103 deflects, it will synchronously drive the second brake block 1101 and the third brake block 1102 connected thereto to rotate clockwise by a certain angle, so that the second brake block 1101 and the third brake block 1102 simultaneously abut against the corresponding hoisting cable 7. When the hydraulic telescopic cylinder 1002 drives the first brake block 1001 to abut against the hoisting cable 7 and applies a certain pressure, it remains in the current state, and each second brake block 1101 and third brake block 1102 also simultaneously abut against the corresponding hoisting cable 7. Moreover, when the second brake block 1101 and the third brake block 1102 move along with the movable block 1103, they will simultaneously abut against the surface of the hoisting cable 7 and cause it to deform, which can effectively increase the contact area between the hoisting cable 7 and each second brake block 1101 and third brake block 1102, and increase the friction force among the three, effectively improving the stability of the adjustable anchor head, preventing the hoisting cable 7 at the adjustable anchor head from shifting when hoisting large goods, resulting in the phenomenon of height deviation of the suspension piece 6, and thus improving the movement stability of the entire cable crane traction system.

[0038] In this embodiment, a groove 12 matching with it is provided on the surface of each of the first brake block 1001, the second brake block 1101 and the third brake block 1102 close to the hoisting cable 7, and a friction plate 13 is embedded in the groove 12.

[0039] As shown in the figure, by providing the groove 12 for placing the friction plate 13 on the surface of each brake block in contact with the hoisting cable 7, the friction force between each brake block and the hoisting cable 7 can be effectively increased (for the convenience of explanation, each brake block refers to each first brake block 1001, second brake block 1101 and third brake block 1102, and the context is the same), thereby effectively improving the stability of the adjustable anchor head, preventing the hoisting cable 7 from shifting under the restriction of multiple brake blocks, and finally improving the braking effect on each hoisting cable 7 and ensuring the stability during the height adjustment of the suspension piece 6.

[0040] In this embodiment, three displacement sensors (not shown in the figure) corresponding to the hoisting ropes 7 one by one are provided on the surface of each connecting housing 501. The working ends of each displacement sensor face the surface of the corresponding hoisting rope 7 and are used to detect the displacement of the hoisting rope 7 between the first brake block 1001 and the third brake block 1102. Each displacement sensor is electrically connected to the corresponding controller.

[0041] As shown in the figure, each third brake block 1102 and the corresponding second brake block 1101 are arranged at left and right intervals on the horizontal plane. When each brake block abuts against the hoisting rope 7 and restricts its movement, the hoisting rope 7 between the first brake block 1001 and the third brake block 1102 also remains in the current position. At this time, the movement state of the hoisting rope 7 is monitored in real time by the corresponding displacement sensor. When the lifting member 6 is hoisting goods, if the displacement sensor detects that the corresponding hoisting rope 7 has a displacement, it indicates that the restriction at the adjustable anchor head is unstable. It is necessary to control the telescopic ends of each hydraulic telescopic cylinder 1002 to continue moving towards the corresponding hoisting wheel 502 to increase the pressure applied to the hoisting rope 7, thereby improving the stability at the adjustable anchor head. Of course, if the displacement sensor can detect the displacement of the hoisting rope 7, the height of the sliding of the lifting member 6 can be compensated by controlling the corresponding first hoisting winch 8 or the second hoisting winch 9 to take in and release the hoisting rope 7, ensuring that the lifting member 6 is at the specified height and improving the precise control of the height of the lifting member 6.

[0042] In this embodiment, a distance sensor (not shown in the figure) for detecting the distance between the lifting member 6 and the connecting housing 501 is provided on the surface of each connecting housing 501, and each distance sensor is electrically connected to the corresponding controller.

[0043] The distance between the lifting member 6 and the carriage 2 can be monitored in real time by the distance sensor, and the height of each lifting member 6 can be monitored in real time. By sending the detected data to the controller, and then taking in and releasing the hoisting rope 7 through the first hoisting winch 8 and the second hoisting winch 9, each lifting member 6 can be controlled to be on the same horizontal plane, ensuring the stability during the hoisting of goods.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
