Description

Technical Field

[0001] The present invention relates to the technical field of electric power maintenance, and in particular to a cable cover quick disassembly and assembly device and a use method thereof. Background Art

[0002] As the length of cables continues to increase, the number of cable manholes also increases relatively, and the number of reserved pipes, the width of the manholes, and the length of the covers also increase accordingly. Therefore, when constructing various manholes, they are mainly selected in fields, urban roads, green areas, residential areas and other places. Therefore, in order to prevent the manhole covers from being stolen and heavy vehicles from fracturing the covers, causing pedestrians to fall and fall, the covers are thickened, which also makes the thickened covers relatively heavy. When manually disassembling and assembling, a hook is generally inserted into the cover opening of the cover to lift the cover, but this method is difficult to start, and there is a safety hazard of the cover falling, so mechanical equipment is needed at this time. However, due to the influence of the environment, some roads cannot allow mechanical equipment to pass through using mechanical equipment, and in areas such as suburban fields, mechanical equipment cannot be coordinated, resulting in limitations in mechanized operations. Summary of the invention

[0003] In view of the deficiencies in the prior art, an object of the present invention is to provide a cable cover quick disassembly and assembly device and a use method, which can quickly disassemble and assemble the cable cover to improve efficiency.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions:

[0005] The present invention provides a device for quickly disassembling and assembling a cable cover plate, comprising: a hanging frame, a bracket, and a base. A hanging rod is installed on the hanging frame, and a cover-lifting column is connected to the bottom of the hanging rod. The cover-lifting column is split from bottom to top into two left and right spring plates. The cover-lifting column and the hanging rod are in a "human" shape structure. The bottom of the cover-lifting column is fixedly connected with an inverted frustum for supporting the edge of the cover-lifting hole of the cover plate.

[0006] The suspension rod is connected with a sleeve, in which a spring is installed. The sleeve is moved forward or backward to realize the separation and the approach of the extension end of the cover column. When the sleeve moves forward, the spring is squeezed, and the sleeve is reset by the rebound force of the spring.

[0007] A convex block is designed on the extending end of the cover-lifting column, and a rail groove is designed on the wall of the sleeve. The rail groove cooperates with the convex block to limit the retreating action of the sleeve due to the rebound of the spring force when the sleeve moves forward.

[0008] A first compression cylinder is installed on the upper part of the bracket, the top of the bracket is connected to the telescopic member, and the first compression cylinder is connected to the telescopic member, and the telescopic member is driven to extend and retract through the first compression cylinder.

[0009] The rear end of the telescopic member is also rotatably connected to the bottom end of the supporting swing member, and a second compression cylinder is connected between the telescopic member and the supporting swing member; the second compression cylinder is used to achieve the up and down angle change of the supporting swing member.

[0010] The top end of the supporting swing member is connected with a rope, and the free end of the rope is connected with a hanging frame. The hanging frame is a symmetrical structure and can swing left and right at the same time to ensure the same angle change.

[0011] The up and down swinging of the supporting swing member is used to control the up and down movement of the rope.

[0012] The front end of the telescopic member is also connected with a pulley for supporting the rope and assisting the lifting and lowering of the cover plate during hoisting.

[0013] A bearing platform is designed on the base, and a partition is vertically installed on the bearing platform.

[0014] A method for using the above-mentioned cable cover quick disassembly and assembly device: when disassembling and assembling the cover, first move the sleeve forward to cooperate with the protrusion on the cover-lifting column, close the left and right spring plates separated by the cover-lifting column, and extend them into the cover-lifting hole, then separate the sleeve from the cover-lifting column, and use the rebound force of the spring to reset the sleeve, and the left and right spring plates of the cover-lifting column begin to separate, and use the inverted frustum fixed at the bottom of the cover-lifting column to fit the edge of the cover-lifting hole, and use the second compression cylinder to extend and retract the supporting swinging part to move up and down, thereby driving the cover to move up and down to complete the cover disassembly and assembly.

[0015] The beneficial effects of the embodiments of the present invention are as follows:

[0016] 1. The present invention uses a sleeve to bring the left and right spring plates separated on the cover-lifting column closer together and extend them into the cover-lifting hole, and realizes vertical lifting through the fitting of the inverted frustum fixed at the bottom of the cover-lifting column with the edge of the cover-lifting hole of the cover plate.

[0017] 2. The lifting frame of the present invention is symmetrical on the left and right, and can swing left and right at the same time to ensure the same angle change. Compared with the existing mechanical equipment, the present invention has the advantages of simple structure, low cost, flexible operation and easy use. It can replace a large number of manual labor to complete the disassembly and transportation of the cover plate, saving time and labor in operation, with high working efficiency and low energy consumption.

[0027] As described in the background art, the existing method is to use a hook to extend into the cover opening of the cover to lift the cover, but this method has the potential safety hazard of the cover falling, and when mechanical equipment is used for assistance, it is often restricted by the environment and has low equipment availability.

[0028] In order to solve the above technical problems, the present invention proposes to provide a cable cover quick disassembly and assembly device, which is not affected by external environmental factors and can be used at any time to quickly disassemble and assemble the cable cover to improve efficiency and avoid safety hazards caused by manual disassembly and assembly.

[0029] like Figure 1-3 As shown, the present invention provides a cable cover plate quick disassembly and assembly device, including: a hanging frame 1, a bracket 2, and a base 3. A hanging rod 17 is installed on the hanging frame 1, and a cover-lifting column 4 is connected to the bottom of the hanging rod 17. The cover-lifting column 4 is split into two left and right spring plates from bottom to top. The cover-lifting column 4 and the hanging rod 17 are in a "human" shape structure. The bottom of the cover-lifting column 4 is fixedly connected with an inverted frustum 18 for resisting the edge of the cover-lifting hole on the cover plate 13.

[0030] Specific as Figure 1 As shown, a first compression cylinder 5 is fixedly mounted on the bracket 2, the top of the bracket 2 is fixedly connected to the telescopic member 6, the first compression cylinder 5 is connected to the telescopic member 6, and the telescopic member 6 is driven to extend and retract by the first compression cylinder 5.

[0031] like Figure 3As shown, a sleeve 11 is connected to the suspension rod 17, and the suspension rod 17 is cylindrical. A spring 12 is installed in the sleeve 11. In order to make the left and right spring plates separated by the cover-lifting column 4 close together, the sleeve 11 connected to the suspension rod 17 needs to be pushed in the direction of the inverted cone 18 until the left and right spring plates fit together. When the sleeve 11 moves forward, the spring 12 is squeezed to generate a rebound force, which will cause the sleeve to move backward. Therefore, a protrusion 15 is designed on the extending end of the cover-lifting column 4, and a rail groove 16 is opened on the side wall of the sleeve 11. Through the cooperation of the protrusion 15 and the rail groove 16, it is ensured that the sleeve 11 will not move backward when squeezing the spring 12.

[0032] like Figure 4 The track groove 16 designed on the wall of the sleeve 11 is a right-angle track groove. The protrusion 15 follows the trajectory of the track groove 16 and reaches the turning point of the track groove 16. The protrusion 15 can be stuck in the short side of the track groove 16 by rotating the sleeve 11. After the cover-lifting column 4 is inserted, the sleeve 11 is rotated to make the protrusion withdraw along the trajectory of the track groove 16, and the sleeve 11 is reset by using the rebound force of the compressed spring 12.

[0033] like Figure 1 As shown, a rope 10 is connected to the top of the supporting swing member 8, and the free end of the rope 10 is connected to the hanging frame 1. The hanging frame 1 is designed to be a symmetrical structure for easy storage, and can swing left and right at the same time when opened for use, ensuring the same angle change, to prevent the problem of one side sinking low during hanging.

[0034] The rear end of the telescopic member 6 is also rotatably connected to the bottom end of the supporting swing member 8, and a second compression cylinder 7 is also connected between the telescopic member 6 and the supporting swing member 8; the second compression cylinder 7 is used to realize the up and down angle change of the supporting swing member 8, and the up and down swing of the supporting swing member 8 is used to control the up and down movement of the rope 10.

[0035] The front end of the telescopic member 6 is also connected to a pulley 9 for supporting the rope 10 and assisting the lifting of the cover plate 13 during hoisting.

[0036] like Figure 6 As shown, the base 3 is designed with a bearing platform, and a partition 14 (such as Figure 1 As shown), the carrying platform is used to store a new cover plate 13 and a just removed cover plate 13 respectively.

[0037] A method for using the above-mentioned cable cover quick disassembly and assembly device: when disassembling and assembling the cover 13, first move the sleeve 11 forward to cooperate with the protrusion 15 on the cover-lifting column 4, close the left and right spring plates separated by the cover-lifting column 4, and extend them into the cover-lifting hole, then separate the sleeve 11 from the cover-lifting column 4, and use the rebound force of the spring 12 to reset the sleeve 11, and the left and right spring plates of the cover-lifting column 4 begin to separate, and use the inverted frustum 18 fixed at the bottom of the cover-lifting column 4 to fit with the edge of the cover-lifting hole, and use the second compression cylinder 7 to extend and retract the supporting swinging member 8 to move up and down, thereby driving the cover 13 to move up and down to complete the disassembly and assembly of the cover 13.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
