Description

Technical Field

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

[0002] Cable crane is a commonly used hoisting equipment for bridge superstructure construction, which consists of a load-bearing system, a traction system, a lifting system, a tower, etc. With the development of my country's economy and society, my country has put forward an urgent demand for large-span bridges with larger spans and stronger bearing capacity. At the same time, it has put forward higher requirements for the hoisting span and hoisting capacity of cable cranes. The steel wire rope of the cable crane traction system repeatedly passes through the overhead crane and the steering wheels anchored at both ends to form a closed loop. At present, the maximum closed length of the steel wire rope used in the cable crane traction system is nearly 20,000 meters. The manufacture and transportation of a single 10,000-meter-level traction steel wire rope faces great difficulties. It often requires multiple steel wire ropes to be connected in series, but the interface of the steel wire rope after series connection is poor in smoothness and the safety risk increases. With the increase of the hoisting span and hoisting capacity of the cable crane, it is particularly important to optimize the routing method of the cable crane traction system when the maximum length of the steel wire rope processing is limited.

[0003] For example, a Chinese patent discloses a bidirectional traction adaptive horse-racing system for a cable hoisting system (patent publication number: CN110386559A). The triangular connecting beam connects the two sets of weighing frame plates into a whole through a connecting shaft, which can adapt to the posture changes of the load-bearing system and meet the large-angle climbing construction of the horse-racing system. The traction wheels of the layered traction system are arranged vertically, so that the number of traction wheels can be sufficient in a limited space to meet the traction needs of large-tonnage heavy objects. At the same time, the small traction guide wheel 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 traction without interfering with each other.

[0004] Although the above technical solution solves the problems of mutual interference between the load-bearing cables and the traction cables in the current horse racing system, and the fixed structure of the sports car resulting in inflexible climbing and limited moving range, it does not improve the weight problem of the cable crane system. In the actual construction process, two groups of sports cars are usually set on the same set of load-bearing cables. There are a total of four groups of sports cars on both sides along the width of the bridge, and they work together with the hanging parts to lift the goods. Among them, the two groups of sports cars on the same set of load-bearing cables correspond to two lifting winches respectively, and the two lifting winches need to use two separate sets of independent lifting cables to control the height of the hanging parts on each group of sports cars respectively. Not only is the installation complicated, but it also greatly increases the total weight of the cable crane system. In the construction of large or super-large bridges, it is also necessary to optimize the routing method of the cable crane traction system and reduce its total weight. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a cable crane adaptive lifting system to solve the problem that in the current cable lifting and traction system, two adjacent groups of sports cars on the same side need to use two separate lifting cables to respectively control the height of the hanging parts, resulting in a heavy total weight of the cable lifting system and the routing of the sports cars and the hanging parts needs to be optimized.

[0007] Furthermore, a controller for controlling the movement of the hydraulic telescopic cylinder is provided on the surface of each of the connecting shells, and the controller is electrically connected to a power supply for supplying electricity and a wireless transmission device for remotely transmitting information, and the power supply is also electrically connected to a power generation component, which is arranged on the connecting shell and provides power through the rotation of the corresponding lifting wheel group, thereby generating current to charge the power supply.

[0008] Furthermore, each of the connecting shells is provided with a second brake unit on a side surface close to the adjacent sports car, and the second brake unit includes a supporting shell arranged on one side of the connecting shell and a plurality of second brake blocks and a plurality of third brake blocks movably arranged on the supporting shell and corresponding to each lifting cable, wherein each second brake block and the corresponding third brake block are respectively fixedly arranged on both sides of the corresponding lifting cable with upper and lower intervals, and the supporting shell is also rotatably connected with a plurality of movable blocks rotating in a vertical plane, and every two second brake blocks and third brake blocks spaced apart from each other are fixed on a corresponding movable block, and one end of each movable block is connected with a transmission rod between the working end of the hydraulic telescopic cylinder, and the transmission rod is rotatably arranged on the surface of the supporting shell, and when the working end of the hydraulic telescopic cylinder moves toward the corresponding lifting wheel direction, the movable block is synchronously driven to rotate through the transmission rod, so that the surfaces of the second brake block and the third brake block simultaneously abut against the corresponding lifting cable and restrict its movement.

[0009] Furthermore, each of the first brake block, the second brake block and the third brake block has a groove on its surface close to the lifting rope, and a friction plate is provided in the groove.

[0010] Furthermore, a plurality of displacement sensors corresponding to the lifting cables are provided on the surface of each of the connecting shells, and a working end of each of the displacement sensors faces the corresponding lifting cable surface and is used to detect the displacement of the lifting cable between the first brake block and the third brake block, and each of the displacement sensors is electrically connected to the corresponding controller.

DETAILED DESCRIPTION

[0016] like Figure 1 to Figure 7 As shown, A cable crane adaptive lifting system includes a plurality of load-bearing cables 1, two groups of sports cars 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 traction cable 3 for towing the two groups of sports cars 2. The side of each group of sports cars 2 facing both ends of the bridge is connected to a corresponding traction winch (the traction winch is arranged at one end of the bridge and is not shown in the figure), and the two groups of sports cars 2 are linked by an auxiliary traction cable 14. Each group of sports cars 2 includes two load-bearing wheel groups 4 suspended on the load-bearing cables 1 and a lifting wheel jointly hinged under the two load-bearing wheel groups 4. The first hoisting winch 8 and the second hoisting winch 9 are respectively arranged on the shores at both ends of the bridge (specifically in combination with the first hoisting winch 8 and the second hoisting winch 9). Figure 3 As shown), one end of the three hoisting ropes 7 is wound up by the first hoisting winch 8, and the other end passes through the two groups of sports cars 2 located on the same side and cooperates with them, and then is wound up at the working end of the second hoisting winch 9; Each of the lifting wheel groups 5 includes a connecting shell 501 hinged to the two load-bearing wheel groups 4 and a plurality of lifting wheels 502 rotatably connected to the surface thereof, wherein 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 is wound around the corresponding lifting wheel 502 (the winding method of the lifting cable 7 and the plurality of lifting wheels 502 is the prior art, and only a simple winding method is shown in the figure of the present invention for the convenience of explanation and description), and each of the connecting shells 501 is provided with a first brake unit 10 for limiting the movement of each lifting cable 7, and the first brake unit 10 is arranged Located on the side close to the adjacent sports car 2, the first brake unit 10 includes three first brake blocks 1001 and a hydraulic telescopic cylinder 1002 that drives each first brake block 1001 to move. The hydraulic telescopic cylinders 1002 are obliquely inserted into the connecting shell 501 and are fixedly connected to each other by bolts and nuts. Each of the first brake blocks 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 toward the corresponding lifting wheel 502 close to the adjacent sports car 2, each first brake block 1001 abuts against the corresponding lifting cable 7 and limits the movement of the lifting cable 7.

[0017] Combination Figure 3As shown in the figure, the cable crane traction system of the present invention is composed of four groups of sports cars 2, and only two groups of sports cars 2 located on the same side are shown in the figure (located on the same side refers to two groups of sports cars 2 suspended on the same load-bearing cable 1, which are synonymous in the context). When it is necessary to control the height of the hanging member 6 on the left group of sports cars 2 (combined with Figure 2 As shown in the figure, the sports car 2 on the left side is firstly controlled to extend the working end of each hydraulic telescopic cylinder 1002 on the sports car 2, so that the surface of each corresponding first brake block 1001 abuts against the corresponding lifting rope 7, and clamps the lifting rope 7 together with the corresponding lifting wheel 502 to limit the movement of the lifting rope 7. For the convenience of explanation, the position where the first brake block 1001 and the lifting wheel 502 clamp the lifting rope 7 together is called an adjustable anchor head, while the lifting rope 7 between the adjustable anchor head and the first lifting winch 8 can move (can be combined with Figure 7 As shown), at this time, the height of the suspension 6 can be controlled by controlling the first hoisting winch 8 to retract and release the hoisting rope 7, without affecting the height of the suspension 6 on the other group of sports cars 2; similarly, the other group of sports cars 2 on the same side as the above-mentioned sports cars 2 can also repeat the above steps, and the movement of the corresponding hoisting rope 7 can be limited by controlling the first brake block 1001, so that the height adjustment of the suspension 6 corresponding to the sports car 2 can be achieved by controlling the second hoisting winch 9. The height adjustment mechanisms of the two suspensions 6 are independent of each other and will not affect each other, so that the first hoisting winch 8 and the second hoisting winch 9 can respectively control the height of the suspension 6 on the two groups of sports cars 2; wherein, in combination with Figure 2 and Figure 7 As shown, by adjusting the length of the auxiliary traction rope 14 between two adjacent groups of sports cars 2, the distance between the two adjacent groups of sports cars 2 can be indirectly adjusted (a winch for winding up the auxiliary traction rope can be installed on each group of sports cars, or components such as hydraulic telescopic cylinders can be installed. This is achievable for those skilled in the art and will not be elaborated on here), thereby realizing the lifting of lifting units of different lengths, which improves the scope of application of the present invention to a certain extent.

[0018] When it is necessary to lower or retract the hanging parts 6 on each group of sports cars 2 at the same time, each first brake block 1001 is controlled not to abut against the lifting rope 7. At this time, only the first hoisting winch 8 can be controlled to retract and release the lifting rope 7 to achieve synchronous adjustment of the heights of the two hanging parts 6, while the second hoisting winch 9 does not operate. Of course, only the second hoisting winch 9 can be controlled to retract and release, while the first hoisting winch 8 does not operate. In addition, the first hoisting winch 8 and the second hoisting winch 9 can be synchronously controlled to retract and release at the same speed, so that the horizontal heights of the two hanging parts 6 can be synchronously adjusted at twice the speed. When the two groups of sports cars 2 move driven by the traction rope 3, the height of the suspension member 6 can be maintained by controlling the first hoisting winch 8 and the second hoisting winch to retract and release the hoisting rope 7, which will not affect the normal operation of the sports car 2. When the sports car 2 approaches one end of the bridge driven by the traction rope 3, since the height of the cable crane traction system gradually decreases from the two ends of the bridge to the middle (this is caused by the deadweight of the cable crane traction system and the lifting of goods), the sports car 2 will be in a climbing state when approaching the two ends of the bridge. At this time, the two groups of sports cars 2 on the same side will show a height difference. Of course, the suspension member 6 will also show a height difference. In order to solve the height difference between the two suspension members 6, the first hoisting winch can be controlled. The retracting and extending speeds of the first hoisting winch 8 and the second hoisting winch 9 are at different speeds, and the height of each suspension member 6 is adjusted by the speed difference between the two. When the height of the suspension member 6 is at the same horizontal plane, the retracting and extending speeds of the first hoisting winch 8 and the second hoisting winch 9 are controlled to remain the same. This can also effectively solve the problem of adjusting the height of the suspension member 6 when the sports car 2 is in a climbing state. Compared with the traditional cable hoist traction system, a group of lifting cables 7 on the two sports cars 2 on the same side is reduced, which greatly reduces the total weight of the cable hoist traction system, improves the stability of the cable hoist traction system under large span and ultra-large span, and compared with the adjustment of the height of the suspension member 6 in the traditional cable hoist traction system, the operation of the present invention is simple and reliable.

[0019] In this embodiment, a controller for controlling the movement of the hydraulic telescopic cylinder 1002 is provided on the surface of each of the connecting shells 501, and the controller is electrically connected to a power supply 16 for supplying electricity and a wireless transmission device for remotely transmitting information (the wireless transmission device can adopt wireless transmission technologies such as 5G and Wi-Fi), and the power supply 16 is also electrically connected to a power generation component 15, which is fixed to the surface of the connecting shell 501 by bolts, and provides power through the rotation of the corresponding lifting wheel group 5, thereby generating current and charging the power supply 16; of course, the power generation component 15 can also be set on the load-bearing wheel group 4, and provide power through the rotation of the load-bearing wheel group 4, and charge the power supply 16.

[0020] The power generation assembly 15 includes a rotor, a housing with a magnetic field, and a coil, and the rotor is connected to a wheel in the lifting wheel assembly 5 by power (combined with Figure 6As shown in the figure), when the lifting wheel group 5 moves, it will drive the rotor to rotate. When the rotor rotates in the housing with the magnetic field, according to Faraday's law of electromagnetic induction, an induced electromotive force will be generated in the coil and the power supply 16 will be charged. Therefore, this technical principle is achievable for those skilled in the art, and the corresponding equipment installation and implementation process will not be described in detail here; when each group of sports cars 2 moves along the length direction of the lifting rope 7, each load-bearing wheel on the load-bearing wheel group 4 will rotate, and of course, the traction wheel will also rotate, and when the height of each hanging member 6 is adjusted, the other lifting wheels 502 on each group of sports cars 2 except for the one corresponding to the first brake block 1001 will also rotate. It will rotate (this is when the adjustable anchor head is present), and the rotating load-bearing wheels and the lifting wheel 502 can generate current through electromagnetic induction and charge the power supply 16, ensuring the normal operation of the power supply 16, the controller, the hydraulic telescopic cylinder 1002 and the wireless transmission device. In addition, when the sports car 2 or the hanging part 6 moves, it will drive the power generation component 15 and continuously charge the power supply 16 through electromagnetic induction, reducing the weight of the power lines separately set from the two ends of the bridge to each group of sports cars 2, without adding additional power lines, simplifying the line of the cable crane traction system, and through the setting of the power generation component 15, there is no need to worry about the power supply 16 being out of power.

[0021] In the present embodiment, each of the connecting shells 501 is provided with a second brake unit 11 on a side surface close to the adjacent sports car 2, and the second brake unit 11 includes a supporting shell 1104 arranged on one side of the connecting shell 501 and a plurality of second brake blocks 1101 and a plurality of third brake blocks 1102 movably arranged on the supporting shell 1104, and each lifting cable 7 corresponds to a second brake block 1101 and a third brake block 1102, wherein each second brake block 1101 and the corresponding third brake block 1102 are respectively fixedly arranged on both sides of the corresponding lifting cable 7 with an upper and lower interval (each third brake block 1102 and the corresponding second brake block 1101 are arranged with a left and right interval on the horizontal plane), and the supporting shell 1104 is also rotatably connected with a plurality of movable blocks 1103 rotating in a vertical plane, and every two movable blocks 1103 correspond to one lifting cable. Cable 7, and every two second brake blocks 1101 and third brake blocks 1102 spaced apart from each other are fixed between the corresponding two movable blocks 1103, one end of each movable block 1103 is connected to the working end of the hydraulic telescopic cylinder 1002 by a transmission rod 1105, the transmission rod 1105 is rotatably arranged on the surface of the support shell 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, and when the working end of the hydraulic telescopic cylinder 1002 moves toward the corresponding lifting wheel 502, the movable block 1103, the second brake block 1101 and the third brake block 1102 are synchronously driven to deflect by a certain angle through the transmission rod 1105, so that the surfaces of the second brake block 1101 and the third brake block 1102 simultaneously abut against the corresponding lifting cable 7 and limit their movement.

[0022] As shown in the combined figure, when it is necessary to adjust the height of the hanging piece 6 under one of the sports cars 2, each hydraulic telescopic cylinder 1002 on the sports car 2 is controlled to start working, and the working end of the hydraulic telescopic cylinder 1002 extends and drives the first brake block 1001 to move toward the corresponding lifting wheel 502. At the same time, the working end of the hydraulic telescopic cylinder 1002 will rotate through the transmission rod 1105 during the extension process, and the rotation of the transmission rod 1105 will drive the corresponding movable block 1103 to deflect (as shown in the combined figure, the torque length between the rotation center of the transmission rod 1105 and the hydraulic telescopic cylinder 1002 is greater than the torque length to the movable block 1103, forming a labor-saving lever that can amplify and increase the torque of the hydraulic telescopic cylinder 1002). After the movable block 1103 is deflected, 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 lifting cable 7. When the hydraulic telescopic cylinder 1002 drives the first brake block 1001 to abut against the lifting cable 7 and applies a certain pressure, it remains in the current state, and each second brake block 1101 and the third brake block 1102 also abuts against the corresponding lifting cable 7 at the same time. Moreover, the second brake block 1101 and the third brake block 1102 will simultaneously abut against the surface of the lifting cable 7 and deform it while moving with the movable block 1103, which can effectively increase the contact area between the lifting cable 7 and each second brake block 1101 and the third brake block 1102, and increase the friction between the three, which can effectively improve the stability of the adjustable anchor head, prevent the lifting cable 7 at the adjustable anchor head from being displaced when the hoist 6 is lifting large goods, resulting in a height deviation of the hoist 6, thereby improving the movement stability of the entire cable crane traction system.

[0023] In this embodiment, each of the first brake block 1001 , the second brake block 1101 and the third brake block 1102 is provided with a groove 12 matched therewith on a surface of one side close to the lifting rope 7 , and a friction plate 13 is embedded in the groove 12 .

[0024] As shown in the figure, by providing a groove 12 for placing the friction plate 13 on the surface of one side of each brake block that contacts the lifting cable 7, the friction force between each brake block and the lifting cable 7 can be effectively improved (for the convenience of explanation, each brake block represents each first brake block 1001, second brake block 1101 and third brake block 1102, consistent with the context), thereby effectively improving the stability of the adjustable anchor head, preventing the lifting cable 7 from being displaced when restricted by multiple brake blocks, and ultimately improving the braking effect on each lifting cable 7, ensuring the stability of the hanger 6 when the height is adjusted.

[0025] In this embodiment, three displacement sensors (not shown in the figure) corresponding to the lifting cables 7 are provided on the surface of each of the connecting shells 501. The working end of each of the displacement sensors faces the corresponding surface of the lifting cables 7 and is used to detect the displacement of the lifting cables 7 between the first brake block 1001 and the third brake block 1102. Each of the displacement sensors is electrically connected to the corresponding controller.

[0026] As shown in the figure, each third brake block 1102 and the corresponding second brake block 1101 are arranged at intervals on the horizontal plane, and when each brake block abuts against the lifting cable 7 and restricts its movement, the lifting cable 7 between the first brake block 1001 and the third brake block 1102 is also maintained at the current position at the same time. At this time, the movement state of the lifting cable 7 is monitored in real time by the corresponding displacement sensor. When the hanging member 6 is hoisting the cargo, if the displacement sensor detects that the corresponding lifting cable 7 is displaced, it indicates that the restriction at the adjustable anchor head is not stable, and it is necessary to control the telescopic end of each hydraulic telescopic cylinder 1002 to continue to move toward the corresponding lifting wheel 502 to increase the pressure applied to the lifting cable 7, thereby improving the stability of the adjustable anchor head; of course, the displacement of the lifting cable 7 can be detected by the displacement sensor, so the height of the hanging member 6 sliding down can be compensated by controlling the corresponding first lifting winch 8 or the second lifting winch 9 to retract and release the lifting cable 7, so as to ensure that the hanging member 6 is at a specified height, thereby improving the precise control of the height of the hanging member 6.

[0027] In this embodiment, a distance sensor (not shown in the figure) for detecting the distance between the hanging part 6 and the connecting shell 501 is disposed on the surface of each connecting shell 501, and each distance sensor is electrically connected to a corresponding controller.

[0028] The distance sensor can monitor the distance between the hanging component 6 and the sports car 2 in real time, and the height of each hanging component 6 in real time. The detected data is sent to the controller, and then the first lifting winch 8 and the second lifting winch 9 are used to retract and release the lifting rope 7, thereby controlling each hanging component 6 to be on the same horizontal plane, thereby ensuring stability when lifting goods.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. 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.
