Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to flexible photovoltaic steel cable laying construction equipment. Background Art

[0002] Currently, flexible photovoltaic projects use two parallel flexible steel cables (typically steel strands) to support and secure photovoltaic panels. The cables typically range in diameter from 8mm to 21.6mm. These cables are delivered to the photovoltaic project site in coils bound with steel straps. The coiled steel strands are manually routed and threaded through the photovoltaic support system's side posts, multiple intermediate supports, and finally the terminal side posts. The entire span, which ranges from over 100 meters to over 1,000 meters, is manually dragged and pulled. The heavy weight and high rigidity of the steel cables make manual dragging difficult. Furthermore, photovoltaic projects are often constructed in mountainous areas or in the wild, creating complex terrain, further increasing the difficulty and safety risks of manual cable threading. Furthermore, the cables must be threaded through fixed slots / holes at the top of the support, which typically range from 2 meters to 7.5 meters above the ground. Manual cable threading requires personnel to manually thread the cables at each support. Summary of the Invention

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0034] Please refer to Figures 1 to 12 The figure shows a flexible photovoltaic cable laying construction equipment. To free up manpower, mechanical equipment replaces manual cable threading. Personnel only need to operate the mechanical equipment to play the role of assistance, monitoring, and control. It includes: cable feeding equipment, traction equipment, steel cable and photovoltaic brackets. The steel cable passes through multiple photovoltaic brackets. One end of the steel cable is wrapped around the cable feeding equipment, and the other end is connected to the steel wire rope on the traction equipment. The cable feeding equipment is capable of automatically unwinding the entire coil of steel strand (steel cable) according to the set speed. The main function of the traction equipment is to use the matching traction rope (flexible plastic-coated steel wire rope) to pull the steel cable from the head end to the tail end of the photovoltaic bracket according to the set traction tension.

[0035] The cable feeding equipment includes: a crawler conveyor 1, a cable feeding generator set 3, a cable feeding hydraulic pump station 6 and a cable feeding walking chassis 9. The crawler conveyor 1, the cable feeding generator set 3 and the cable feeding hydraulic pump station 6 are all installed on the cable feeding walking chassis 9. The crawler conveyor 1 is used to feed the steel cable to the traction equipment, the cable feeding walking chassis 9 is used to drive the walking, the cable feeding generator set 3 is used to supply energy to all the electrical mechanisms of the cable feeding equipment, and the cable feeding hydraulic pump station 6 is used to drive all the hydraulic mechanisms of the cable feeding equipment; among them, the cable feeding equipment needs to solve the problem of controllable unwinding and unfolding of 4.5-ton steel strands. The size of the incoming coil of this steel strand is: 1.5 meters in diameter, 800 mm in width, about 800 mm in inner hollow diameter, and a total weight of about 4.5 tons. It is a hollow coil without a support reel; moreover, the steel strands The stranded wire itself has very high elasticity and hardness. After the trapped steel belt is cut off, the steel strand will pop out like a spring. Therefore, when unwinding, a device is needed to keep control of the continuously unfolded steel strand and control the linear speed of unwinding. When unwinding, the entire roll of steel strand also requires an external damping force to prevent the entire roll of steel strand from rotating freely, otherwise it will become loose during the unwinding process. In addition, after the steel strand is threaded, it is necessary to perform a tensioning action on the steel cable, that is, to tighten the entire threaded steel cable to a preset tension value, and then fix the steel cable with a locking clamp on the outside of the two side columns. Then during this tensioning process, the cable feeding equipment also needs to have a clamping function to firmly grasp the steel cable and provide a clamping force for the traction equipment at the tail end to tension the steel cable.

[0036] The traction equipment includes: a winding device 10, a traction hydraulic pump station 11, a power distribution cabinet 12, a traction traveling chassis 13, a wire arrangement mechanism mounting base 14, a wire arrangement mechanism 15, and a traction generator set 16. The winding device 10, the traction hydraulic pump station 11, the power distribution cabinet 12, the wire arrangement mechanism mounting base 14, and the traction generator set 16 are all mounted on the traction traveling chassis 13. The winding device 10 is used to wind the wire rope for traction. The wire arrangement mechanism 15 is slidably mounted on the wire arrangement mechanism mounting base 14. The wire arrangement mechanism 15 is used to adjust the winding position of the wire rope on the winding device 10. The traction hydraulic pump station 11 is used to drive all hydraulic mechanisms of the traction equipment. The traction generator set 16 is used to power all electrical mechanisms of the traction equipment. The power distribution cabinet 12 is used for power distribution. The main problems that need to be solved in the traction equipment are to provide controllable traction force and control the arrangement of the flexible traction wire rope during winding and unwinding. The final motor output torque is calculated based on the real-time winding radius and the set traction force. In addition, protection and alarm controls for special operating conditions such as overload and stall must also be considered.

[0037] Furthermore, because photovoltaic projects typically install panels in rows, flexible cables are also spaced apart. Both our cable delivery and traction equipment must be capable of autonomous mountaineering operations and independent power supply. Once a set of two cables is threaded and secured, the equipment moves to the next workstation to continue construction. This autonomous operation requires comprehensive consideration of mountain operations, climbing angles, stability on sloping surfaces, maneuverability, and rollover prevention.

[0038] Road transport of the equipment also required a solution. During transport, the maximum width of the equipment could not exceed 3.2 meters, and the height could not exceed 3 meters. However, considering the equipment's stability during tilting and the inherent layout limitations of the device, the crawler chassis needed to be designed with a retractable width. The feeder belt and clamping mechanism on the upper portion of the cable feeder were designed to ride on a set of retractable guide rails driven by pneumatic cylinders. During transport, both crawler tracks are retracted to their narrowest position, and the feeder belt and clamping mechanism are also retracted into the equipment by pneumatic cylinders for easy transportation.

[0039] Furthermore, due to the large span of the cable, which often crosses mountainous terrain and obstacles, and the need for real-time synchronization and coordination between the cable feeding and traction equipment, real-time wireless communication and data transmission between the host devices at both ends is required. Furthermore, all operations must be remotely controlled wirelessly by a host computer (a handheld mobile control terminal). The host computer can be held by the operator, allowing them to monitor the rigging's progress and the traction status in real time.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the implementation and protection scope of the present invention.

[0050] The present invention also has the following implementation modes based on the above:

[0051] In a further embodiment of the present invention, the cable-feeding walking chassis 9 and the traction walking chassis 13 adopt the same chassis design method, referring to the solution of the crawler chassis of the excavator, and taking advantage of the crawler chassis's high center bottom and good passability. At the same time, a new central load-bearing main beam is specially designed, equipped with 4 sets of jacking mechanisms and 4 sets of telescopic mechanisms. The function of the jacking mechanism is to use 4 sets of hydraulic cylinders to lift the entire crawler chassis together with the upper equipment off the ground, so as to facilitate the lateral telescopic adjustment of the width of the crawlers on both sides; the 4 sets of telescopic mechanisms are two crawlers on both sides, which are driven by two sets of telescopic hydraulic cylinders to move laterally and telescope as a whole. In order to ensure that the telescopic mechanism has sufficient load-bearing capacity, a square outer sleeve made of steel plates is used, and the interior is in the form of a rectangular square tube.

[0052] In a further embodiment of the present invention, the cable feed generator set 3 and the traction generator set 16 utilize the same power supply method, both of which are equipped with diesel generator sets, and the generator sets provide a unified power source. The power distribution control cabinet drives and controls the hydraulic pump station, variable frequency motor, valve body, cylinder, air pump, and other devices.

[0053] In a further embodiment of the present invention, the cable feeding device unwinds using a prefabricated gripper 4 with electrically openable and closed sides. The gripper 4 comprises six internal sets of support claws 403 and a limit plate 404. The limit plate 404 is made of steel plate, and the support claws 403 are welded from a square tube. The gripper 4 is entirely welded from a steel plate, a square tube, and a rotating sleeve 404. This provides clamping support and lateral fixation for the coiled steel strand (steel cable), preventing the strand from unwinding or becoming tangled during unwinding.

[0054] In a further embodiment of the present invention, the gripper jig 4 is rotatably mounted on a gripper jig mounting base 402 via a central rotating shaft sleeve 404 and an axis. The gripper jig mounting base 402 is mounted on a set of horizontally movable guide rails. The gripper jig mounting base 402 is capable of horizontal movement along the guide rails via a gripper jig travel screw 909 at its base and a drive motor, thereby enabling the gripper jig 4 to open and close. The gripper jig mounting base 402 on one side is equipped with a motor, a reducer, and a brake chuck that drive the limit plate 404. The gripper jig 4 drives the cable drum 5 through vector frequency conversion damping to passively unwind.

[0055] In a further embodiment of the present invention, in order to prevent the uncontrolled unwinding and ejection of the steel strand, a crawler conveyor 1 consisting of two groups of wide belts that can be opened and closed is also provided. The crawler conveyor 1 is composed of two upper and lower groups of wide belts that can rotate independently. The belts are driven by a motor and a reducer and can be frequency-controlled. The opening and closing of the belts are driven by a set of conveyor lifting cylinders 103. The upper belt bracket of the conveyor crawler 101 slides up and down on the plated round steel by two sets of guide bearings on the back to achieve positioning lifting and guiding. During operation, the upper and lower belts are driven by the conveyor lifting cylinders 103 to clamp the steel cable and provide unwinding traction. The entrance and exit of the crawler are provided with positioning and guiding guide rollers to control the feeding of the steel cable along the conveying direction of the crawler. Because the cable drum 5 is connected to the unwinding main shaft variable frequency motor 8 via the gripper jig 4, the unwinding variable frequency motor, controlled by the inverter, constantly provides a damping magnetic field to prevent the cable drum 5 from rotating. When the crawler conveyor is running, the belt provides a pulling force to the steel strands sufficient to overcome the damping magnetic field of the unwinding variable frequency motor. At this time, the steel strands are controlled to be unwound from the cable drum 5 in an orderly and constant speed, thus achieving constant and controllable cable feeding.

[0056] In a further embodiment of the present invention, the clamping device 2 comprises a micro-shaped hydraulic cylinder 204, a matching clamping device mounting base 201, upper and lower clamping plates, and a clamping device limiting roller 205. When the cable needs to be tensioned, the micro-shaped hydraulic cylinder 204 drives the upper clamping plate 203 downward, which cooperates with the lower clamping plate 202 to clamp the cable, thereby securing the cable to the cable feeding device. Because the cable feeding device is very heavy (over 10 tons), it provides sufficient overall clamping force to cooperate with the tail-end pulling device to tension the rigging.

[0057] In a further embodiment of the present invention, since the crawler conveyor 1 and the clamping device 2 must be arranged in sequence on a line and must be opposite to the center line of the cable drum 5, and ensure that there is a certain distance between the entrance of the crawler conveyor 1 and the edge of the cable drum 5, because the steel strand is particularly hard, the steel strand cannot be irreversibly bent due to excessive bending when it is unfolded; so the overall width of this combination in the working state will exceed the allowable transportation width of the equipment, so an independent set of brackets is used for the crawler conveyor and the clamping device, and a retractable guide rail is used to connect this bracket to the vehicle body bracket, and the extension and retraction are driven by the cable feeding opening and closing telescopic cylinder 902; it is unfolded in the working state and retracted in the transportation state.

[0058] In a further embodiment of the present invention, the traction device primarily rotates a welded drum 1004, driven by a variable frequency motor driving a reducer. A flexible steel wire rope is wound around drum 1004, the head end of which is secured to the inner wall of drum 1004. The traction force is provided by the rope wound around the drum. Vector control of the frequency converter, combined with a PLC's calculation of the real-time radius of the rope wound around drum 1004, generates a torque value that can be controlled in real time based on the tension set on the touchscreen.

[0059] In a further embodiment of the present invention, taking into account the different traction distances in the later stage, the drum 1004 for winding the traction rope is replaceable and detachable, so one end of the clamping drum 1004 is a winding sliding seat 1001 that can be opened horizontally, and the other side is a winding fixed seat 1002. After the winding sliding seat 1001 is opened, the drum 1004 can be completely removed.

[0060] In a further embodiment of the present invention, a cable arrangement mechanism 15 driven by a servo motor is provided to ensure that the traction ropes are neatly arranged when being retracted and released. The mechanism mainly comprises a servo motor, a precision ball screw, a guide linear bearing, a cable arrangement mechanism mounting base 14, a pressure wheel 1502, and a damping wheel 1504.

[0061] In a further embodiment of the present invention, the rotation of the drum 1004 can be jogged, and the forward / reverse jogging can enter the forward winding traction operation mode. In the operation mode, the drum drive inverter will switch to the torque mode; the real-time output is automatically controlled according to the set tension.

[0062] In a further embodiment of the present invention, the efficiency of cable laying and threading is improved, the labor intensity of personnel is reduced, and the safety risk is reduced.

[0063] In a further embodiment of the present invention, the overall construction rhythm of the new flexible photovoltaic project is changed, the overall efficiency is improved, and favorable support is provided for the early commissioning of the photovoltaic project engineering equipment.

[0064] In a further embodiment of the present invention, the grab jig 4 is slidably installed on the cable feeding walking chassis 9 by means of a screw nut, and the two grab jig walking screws 909 are driven to rotate separately by a motor to realize the approach and distance of the two grab jig mounting seats 402. When it is necessary to clamp the cable drum 5, the two grab jig mounting seats 402 first move away from each other. After the cable drum 5 is moved between the two limit disks 404, the two grab jig mounting seats 402 approach each other until the two limit disks 404 respectively rest against the front and rear end surfaces of the cable drum 5. The support claws 403 on the inner sides of the two limit disks 404 are used to support the cable drum 5 and cooperate with each other. The main shaft frequency conversion motor 8 is used to drive the two limit disks 404 and the cable drum 5 to rotate.

[0065] In a further embodiment of the present invention, the crawler conveyor 1 is slidably installed on the cable chassis mounting bracket 907 along the conveyor sliding track 908. During the rotation of the cable drum 5, the outer diameter of the cable drum 5 gradually decreases as the cable is gradually pulled out. The crawler conveyor 1 slides along the conveyor sliding track 908 to adapt to the cable drums 5 with different outer diameters.

[0066] In a further embodiment of the present invention, the steel cable is located between the upper conveyor belt 101 and the lower conveyor belt 102. The upper conveyor belt 101 and the lower conveyor belt 102 both adopt a single motor-driven crawler mechanism. The upper conveyor belt 101 and the lower conveyor belt 102 can work together to pull the steel cable. The upper conveyor belt 101 can be raised and lowered in the vertical direction under the joint action of the two conveyor lifting cylinders 103 to adjust the distance between the upper conveyor belt 101 and the lower conveyor belt 102, which is suitable for steel cables of different specifications.

[0067] In a further embodiment of the present invention, the upper clamping plate 203 and the lower clamping plate 202 cooperate with each other. Driven by the micro-anisotropic oil cylinder 204, the upper clamping plate 203 can press the steel cable onto the lower clamping plate 202 to achieve the clamping function.

[0068] In a further embodiment of the present invention, the steel cable is limited by providing a conveyor limiting roller 104 and a clamping device limiting roller 205 to ensure that the steel cable must pass through the crawler conveyor 1 and the clamping device 2 during the cable feeding process.

[0069] In a further embodiment of the present invention, the hydraulic scissors 7 are suspended on the cable feeding walking chassis 9 and driven to open and close by a hydraulic cylinder to achieve shearing of the steel cable.

[0070] In a further embodiment of the present invention, the cable fixing plate 1501 is slidably installed on the mounting plate 1402 through the cable displacement slide rail 1403, and the cable fixing plate 1501 is driven by a motor to reciprocate along the cable displacement slide rail 1403 to adjust the winding arrangement of the wire rope on the drum 1004.

[0071] In a further embodiment of the present invention, the cable arrangement mechanism 15 is as follows: Figure 11 As shown, the clamping wheel 1502 is located on the vertical symmetry line of the two damping wheels 1504. By rotating the handle 1505, the clamping wheel 1502 can be moved downward to compress the wire rope.

[0072] In a further embodiment of the present invention, the winding sliding seat 1001 adopts the same screw nut sliding mechanism as the gripping jig 4 to realize the sliding of the winding sliding seat 1001, and its cooperation with the winding fixed seat 1002 to load and unload the roller 1004 and drive the rotation is the same as the principle of loading and unloading and driving the rotation of the steel cable drum 5 by the gripping jig 4.

[0073] In a further embodiment of the present invention, Figure 1 As shown, during the installation process of the photovoltaic bracket, a steel wire rope is passed through it, one end of the steel wire rope is wound on the traction device, a steel cable drum 5 is installed on the cable feeding device, and the other end of the steel wire rope is connected to the steel cable of the steel cable drum 5. The cable feeding device is used to drive the steel cable drum 5 to unfold, and the cable feeding device is used to tighten the steel wire rope, pulling the steel cable of the steel cable drum 5 along the walking path of the steel wire rope to pass through the photovoltaic bracket in sequence until the cable insertion is completed, and the hydraulic scissors 7 cut the steel cable of the steel cable drum 5.
