Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a reversible cable hoisting frame for cable laying. Background Technology

[0002] Photovoltaic modules are the core component of solar power systems, generating electricity by converting sunlight into electrical energy. A photovoltaic module is mainly composed of eight core materials, including solar cells, encapsulant film, backsheet, glass, aluminum alloy frame, solder strip, junction box, and silicone sealant. During the construction of photovoltaic modules, cable laying and installation is a critical step, affecting not only the system's construction cost but also its operational reliability and ease of maintenance. Therefore, cable laying equipment is required to lay the cables.

[0003] Currently, when laying cables, the usual method is to first place the cable reel with the cable wound on it on a support frame, and then transport the cable using a cable conveyor. When the cable arrives at the construction site, the reel is usually placed upright or flat. Then, a crane is used to lift the reel and place it in the support frame. If the reel is placed upright, the crane needs to first lay the upright reel flat before lifting it again and placing it in the support frame. The entire process requires manual assistance. Since the cable reel with the cable wound is very heavy, there are certain risks when assisting with manual operation. If the reel is laid flat, a metal rod can be inserted into the reel first, and then the crane or forklift can be used to move the reel directly to the support frame.

[0004] To address the aforementioned issues, existing devices first lift the cable reel using a hoisting mechanism. Then, multiple double-headed hydraulic cylinders drive two moving plates closer together, clamping the reel between two clamping plates. Two inserts are then inserted into the reel, and a 90-degree rotation via a connecting column flips the reel from a standing position to a flat position. However, in actual operation, the cable reel must first be lifted, and then the connecting column must be rotated to drive the reel's rotation. This increases the time required to lift the reel and the risk of it falling. Furthermore, the reel's orientation must be determined before the flipping mechanism can be driven to flip it, making the operation quite cumbersome. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a reversible cable hoisting frame for cable laying, which can automatically flip vertical cable reels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reversible cable laying cable hoist includes a lifting mechanism and a reversing mechanism located at the front end of the lifting mechanism. The reversing mechanism includes a worktable abutting against the front end of the lifting mechanism, a conveyor belt longitudinally embedded in the middle of the worktable, a pair of guide plates symmetrically arranged on the upper surface of the worktable and located on either side of the conveyor belt, a detection component fixed to the upper surface of the worktable and covering the outer front ends of the two guide plates, a reversing component located in front of the detection component and cooperating with the detection component to achieve cable reel reversal, and a pair of symmetrically inclined connecting plates fixed to the front end of the worktable and whose front ends pass through the reversing components and abut against the ground. The two guide plates gradually tilt towards each other from front to back. The detection component includes a plate fixed to the upper surface of the worktable. The system includes a lifting sub-assembly mounted on the outer side of the front end of two guide plates and a gravity sensor connected to the lifting sub-assembly and located between the two guide plates; the tilting assembly includes a mounting ring embedded on the front side of the upper surface of the worktable, a rotating ring rotatably mounted on the front end face of the mounting ring, a pair of linear actuators symmetrically fixed on both sides of the inner sidewall of the rotating ring, a pair of clamping members symmetrically fixed on the telescopic ends of each linear actuator, and a drive sub-assembly located on one side of the mounting ring for driving the rotating ring to rotate; the front end face of the worktable has a vertically extending channel that extends to the lower surface of the mounting ring and allows a cable reel to pass through, a lifting plate is vertically slidably mounted in the channel, and a return spring is provided between the lifting plate and the channel; the gravity sensor is electrically connected to the drive sub-assembly and the linear actuators.

[0008] More preferably, the lifting sub-assembly includes a mounting frame fixed to the upper surface of the workbench and covering the outer side of the front end of the two guide plates, an electric push rod vertically fixed to the lower surface of the middle part of the mounting frame and located between the two guide plates, and a mounting plate fixed to the telescopic end of the electric push rod; the gravity sensor is fixed to the front of the mounting plate.

[0009] More preferably, the drive sub-assembly includes a rotating gear fixedly sleeved on the outside of the rotating ring, a drive gear rotatably disposed in front of the mounting ring and meshing with the rotating gear, and a rotating motor fixedly disposed behind the mounting ring with its drive end passing through the mounting ring and fixedly connected to the shaft end of the drive gear; the gravity sensor is electrically connected to the rotating motor.

[0010] More preferably, the lifting mechanism includes a base placed on the ground and fixed to the rear end face of the workbench, a lifting assembly placed on the base, and a pair of clamping assemblies symmetrically arranged in the lifting assembly for fixing the cable reel.

[0011] More preferably, the lifting assembly includes a support plate that abuts against the base, a balance beam that is parallel to the support plate above the support plate, four support columns that are fixed between the support plate and the balance beam and distributed around the support plate, and lifting rings that are fixed around the upper surface of the balance beam; a pair of clamping assemblies are respectively provided on the left and right sides of the upper surface of the support plate.

[0012] More preferably, each clamping assembly includes a slide rail laterally embedded on the upper surface of the support plate, a bidirectional lead screw rotatably mounted in the slide rail, a pair of limiting plates symmetrically arranged on both sides of the bidirectional lead screw and threaded to the two ends of the bidirectional lead screw at their lower parts, a pair of limiting arc plates fixed on the opposite side of the two limiting plates, and a drive motor fixed on one side of the support plate and whose drive end passes through the support plate and the slide rail and is fixedly connected to the shaft end of the bidirectional lead screw; the lower parts of the two limiting plates are slidably connected to the two ends of the slide rail.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the vertically placed cable reel exerts pressure on the gravity sensor during movement, causing the flipping component to flip the cable reel. In contrast, the horizontally placed cable reel does not exert pressure on the gravity sensor, and the flipping component does not operate. This achieves automatic determination of the cable reel's position, eliminating the need for manual judgment of the cable reel's placement orientation before activating the flipping mechanism to flip the vertical cable reel. The operation is relatively simple. Furthermore, when flipping the vertical cable reel, there is no need to suspend it, reducing the time the cable reel spends in the air and lowering the risk of it falling.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] A reversible cable laying cable hoist includes a lifting mechanism 1 and a reversing mechanism 2 disposed on the front end face of the lifting mechanism 1. The reversing mechanism 2 includes a workbench 21 abutting against the front end face of the lifting mechanism 1, a conveyor belt 22 longitudinally embedded in the middle of the workbench 21, a pair of guide plates 23 symmetrically disposed on the upper surface of the workbench 21 and located on both sides of the conveyor belt 22, a detection component 24 fixed to the upper surface of the workbench 21 and covering the front outer sides of the two guide plates 23, a reversing component 25 disposed in front of the detection component 24 on the workbench 21 and cooperating with the detection component 24 to realize the reversing of the cable reel, and a pair of symmetrically inclined connecting plates 26 fixed to the front end face of the workbench 21 and whose front parts pass through the reversing component 25 and abut against the ground. The two guide plates 23 gradually tilt towards each other from front to back. The detection component 24 includes a component fixed to the upper surface of the workbench 21 and covering the front outer sides of the two guide plates 23. The lifting sub-assembly 241 and the gravity sensor 242, which is connected to the lifting sub-assembly 241 and disposed between the two guide plates 23, are included. The flipping assembly 25 includes a mounting ring 251 embedded in the front side of the upper surface of the worktable 21, a rotating ring 252 rotatably mounted on the front end face of the mounting ring 251, a pair of linear actuators 253 symmetrically fixed on both sides of the inner sidewall of the rotating ring 252, a pair of clamping members 254 symmetrically fixed on the telescopic ends of each linear actuator 253, and a drive sub-assembly 255 disposed on one side of the mounting ring 251 for driving the rotating ring 252 to rotate. The front end face of the worktable 21 has a vertically opened channel 211 extending to the mounting ring and allowing the cable reel to pass through. A lifting plate 212 is vertically slidably disposed in the channel 211, and a return spring 213 is disposed between the lifting plate 212 and the channel 211. The gravity sensor 242 is electrically connected to the drive sub-assembly 255 and the linear actuators 253.

[0026] When the cable reel is pushed from the connecting plate 26 to the workbench 21 during use, if the cable reel is vertically positioned, its front end will apply pressure to the gravity sensor 242 during movement. After the gravity sensor 242 senses the gravity, the two linear actuators 253 will first drive the two clamping members 254 to clamp the cable reel from both sides. Then, the drive sub-assembly 252 will rotate the rotating ring 252 ninety degrees, thus rotating the cable reel from a vertical to a horizontal position. Next, the two linear actuators 253 will drive the two clamping members 254 to move to both sides, causing the cable reel to disengage from the clamping members. The rear drive sub-assembly 252 drives the rotating ring 252 to rotate in the opposite direction to the initial position. At this time, the front end of the cable reel is located on the upper surface of the worktable 21. Under the transmission of the conveyor belt 22, it moves towards the lifting mechanism 1. During the movement, it is guided by the two guide plates 23 to move towards the center, so that when the cable reel is transmitted to the lifting mechanism 1, it is located in the middle of the lifting mechanism 1. This makes the lifting mechanism 1 as stable as possible during the lifting process, thereby reducing the possibility of the cable reel shifting or even falling during the lifting process, thus improving the safety when using the device. In this device, the center point of the rotating ring 252 is flush with the middle position of the upper surface of the worktable.

[0027] As a possible implementation of this solution, preferably, the lifting sub-assembly 241 includes a mounting frame 2411 fixed to the upper surface of the workbench 21 and covering the outer side of the front end of the two guide plates 23, an electric push rod 2412 vertically fixed to the lower surface of the middle part of the mounting frame 2411 and located between the two guide plates 23, and a mounting plate 2413 fixed to the telescopic end of the electric push rod 2412; the gravity sensor 242 is fixed to the front of the mounting plate 2413; the extension of the telescopic end of the electric push rod 2412 can be adjusted according to the height of the cable reel, so as to avoid the situation where the gravity sensor 242 cannot detect the cable reel when the diameter is low.

[0028] As a possible implementation of this solution, preferably, the drive sub-assembly 255 includes a rotating gear 2551 fixedly sleeved on the outside of the rotating ring 252, a drive gear 2552 rotatably disposed in front of the mounting ring 251 and meshing with the rotating gear 2551, and a rotating motor 2553 fixedly disposed behind the mounting ring 251 with its drive end passing through the mounting ring 251 and fixedly connected to the shaft end of the drive gear 2552; the gravity sensor 242 is electrically connected to the rotating motor 2553; the rotating motor 2553 drives the drive gear 2552 to rotate, and under the meshing action, drives the rotating gear 2552 and the rotating ring 252 to rotate, thereby driving the cable reel to flip.

[0029] As a possible implementation of this solution, preferably, the lifting mechanism 1 includes a base 11 placed on the ground and fixed to the rear end face of the workbench 21, a lifting assembly 12 placed on the base 11, and a pair of clamping assemblies 13 symmetrically arranged in the lifting assembly 12 for fixing the cable reel; by clamping the cable reel with the clamping assembly 13, the occurrence of the cable reel falling out of the lifting assembly 12 during the lifting process can be avoided as much as possible, further improving the safety performance when using this device.

[0030] As a possible implementation of this solution, preferably, the lifting assembly 12 includes a support plate 121 that abuts against the base 11, a balance beam 122 parallel to the support plate 121, four support columns 123 fixed between the support plate 121 and the balance beam 122 and distributed around the support plate 121, and lifting rings 124 fixed around the upper surface of the balance beam 122; a pair of clamping assemblies 13 are respectively provided on the left and right sides of the upper surface of the support plate 121; when lifting the cable, the lifting rope is passed through the four lifting rings 124, and then the lifting assembly 12 and the cable reel clamped by the clamping assembly 13 are lifted by a crane or other lifting equipment.

[0031] As a possible implementation of this solution, preferably, each clamping assembly 13 includes a slide rail 131 laterally embedded in the upper surface of the support plate 121, a bidirectional lead screw 132 rotatably mounted in the slide rail 131, a pair of limiting plates 133 symmetrically arranged on both sides of the bidirectional lead screw 132 with their lower parts threaded to both ends of the bidirectional lead screw, a pair of limiting arc plates 134 respectively fixed to the opposite side of the two limiting plates 133, and a drive motor 135 fixed to one side of the support plate 121 with its drive end passing through the support plate 121 and the slide rail 131 and then fixedly connected to the shaft end of the bidirectional lead screw 132; the lower parts of the two limiting plates 133 are slidably connected to both ends of the slide rail 131; the bidirectional lead screw 132 is driven to rotate by the drive motor 136, thereby causing the two limiting plates 135 to move closer to each other along the slide rail 131, so that the two limiting arc plates 134 clamp the cable reel from both sides.

[0032] As a possible implementation of this solution, preferably, a pair of reinforcing components 14 are symmetrically arranged between the two limiting plates 133. Each set of reinforcing components 14 includes a pair of constraint straps 141 respectively fixed to the upper surface of the two limiting plates 133, a first connecting buckle 142 fixed to the movable end of one of the constraint straps 141, and a second connecting buckle 143 fixed to the movable end of the other constraint strap 141 and cooperated with the first connecting buckle 142 for fixation. The cooperation of the first connecting buckle 142 and the second connecting buckle 143 can fix the two constraint straps 141, thereby further improving the stability of the two limiting plates 133 when clamped.
