Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically to a power pipe cutting device for power construction. Background Technology

[0002] Electrical conduits are products made by hot-dip plastic coating of PE (modified polyethylene) or internal and external coating of epoxy resin, possessing excellent corrosion resistance. The coating itself also has good electrical insulation properties, preventing electrolytic corrosion. They have low water absorption, high mechanical strength, and a low coefficient of friction, enabling long-term use. Furthermore, they effectively prevent damage from plant roots and soil stress.

[0003] For example, application number CN202323151296.0 describes a utility model relating to the field of power construction technology, specifically a power pipe cutting device for power construction. The device includes two mounting rods, each with two support rods fixedly connected to its lower end. Each support rod has a base fixedly connected to its lower end. Each mounting rod has a load-bearing rod fixedly connected to its upper front end. A load-bearing plate is fixedly connected to the front end of each load-bearing rod. A cutting mechanism is fixedly connected to the lower end of the load-bearing plate. Two fixing components are fixedly connected between the two mounting rods. This utility model's power pipe cutting device, by using fixing components, allows for downward rotation of corresponding fastening plates via two knobs. Simultaneously, corresponding springs deform until both fastening plates are in contact with and tightly press against the power pipe, thus achieving clamping and fixing of the power pipe. This eliminates the need for continuous manual pressing of the power pipe, saving manpower and offering a simple and convenient solution.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of cutting power pipes into different lengths for easy assembly during construction, existing power pipe cutting devices still have the following shortcomings: Existing power pipe cutting devices typically rely on manual arm pressure to fix the power pipe during cutting, which is laborious. Although the power pipe can be tightened by turning the screw after passing through the fixing ring, thus fixing it with external force for cutting, repeatedly tightening or loosening the bolts is very time-consuming when cutting large quantities of power pipes. Therefore, this not only reduces the efficiency of power pipe replacement but also the efficiency of power pipe cutting supply. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a power pipe cutting device for power construction, which has the advantage of auxiliary quick fixing. It solves the problem that after the power pipe is inserted into the fixing ring, although the fixing plate can be tightened against the power pipe by turning the screw to fix the power pipe with external force for cutting, when a large number of power pipes need to be cut, it is very time-consuming to repeatedly tighten or loosen the bolts. Therefore, it not only reduces the efficiency of power pipe replacement, but also reduces the cutting supply efficiency of power pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power pipe cutting device for power construction, comprising a first support, a second support, a fixing ring, and a cutting device. Two fixing rings are provided, with their two sides fixedly connected to the inner sides of the first and second supports. The bottom sides of the cutting device are fixedly connected to the left side of the top of the first and second supports. A sliding groove is provided on the top of the first support, and an L-shaped plate is slidably connected to the inner wall of the sliding groove. A stepping groove is provided on the bottom of the front side of the L-shaped plate, and support and reset components are fixedly connected to the top of both sides of the L-shaped plate.

[0007] In a preferred embodiment of this utility model, the support and reset assembly includes an extension block, the inner side of which is fixedly connected to the top of both sides of the L-shaped plate, a spring is fixedly connected to the bottom of the extension block, the other end of the spring is fixedly connected to the top of the first bracket, and a limit assembly is fixedly connected to the bottom of the extension block.

[0008] In a preferred embodiment of this invention, the limiting component includes a straight rod, the top of which is fixedly connected to the bottom of the extension block. Limiting grooves are provided on both sides of the top of the first bracket. The surface of the straight rod is slidably connected to the inner wall of the limiting groove. The straight rod is located inside the spring.

[0009] As a preferred embodiment of this utility model, an anti-detachment block is fixedly connected to the bottom of the straight rod, and the top of the anti-detachment block is in contact with the bottom of the first bracket.

[0010] As a preferred embodiment of this utility model, an adapter plate is fixedly connected to the rear side of the bottom of the L-shaped plate, and the bottom of the adapter plate is arranged in an inverted V shape.

[0011] As a preferred embodiment of this invention, a resistance-increasing pad is fixedly connected to the bottom of the adapter plate, and the resistance-increasing pad is made of rubber.

[0012] As a preferred embodiment of this utility model, expansion plates are fixedly connected to the bottom of both the front and back sides of the L-shaped plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting an L-shaped plate, allows the user to insert the power pipe into the fixing ring and then pull the L-shaped plate downwards through the foot groove, causing the support and reset assembly to retract. This allows the L-shaped plate to press the power pipe down, thus quickly fixing the power pipe with external force. Finally, the cutting device can be activated to cut the power pipe. This solves the problem that although the power pipe can be fixed by tightening the screw to drive the fastening plate against the power pipe after it is inserted into the fixing ring, which is very time-consuming when cutting a large number of power pipes, thus reducing the efficiency of power pipe replacement and cutting supply. This invention achieves the effect of assisting in rapid fixing.

[0015] 2. This utility model, by setting up a support and reset component, allows the extension block to descend along with the L-shaped plate as the user applies downward pressure through the foot groove. This causes the spring to be compressed, deform, and generate a rebound force. When the user releases pressure on the foot groove, the L-shaped plate quickly and automatically resets through the spring's rebound force and the cooperation of the extension block. Furthermore, the L-shaped plate does not interfere with the insertion of the power pipe before it is inserted into the fixing ring, thus improving the user's ease of operation.

[0016] 3. By setting a limiting component, this utility model allows the spring to be compressed and deformed during the process of the extension block descending along with the L-shaped plate, thereby generating a rebound force. The straight rod slides in the limiting groove along with the movement of the extension block, thus constraining the deformation of the spring and preventing the spring from twisting during deformation, which would prevent the rebound force from being released normally. This improves the stability when the L-shaped plate is automatically raised and reset using the spring rebound force. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a power pipe cutting device 4 for power construction, including a first support 1, a second support 2, a fixing ring 3 and a cutting device 4. Two fixing rings 3 are provided, and the two sides of the fixing ring 3 are fixedly connected to the two sides of the inner side of the first support 1 and the second support 2. The two sides of the bottom of the cutting device 4 are fixedly connected to the left side of the top of the first support 1 and the second support 2. A sliding groove 5 is provided on the top of the first support 1, and an L-shaped plate 6 is slidably connected to the inner wall of the sliding groove 5. A stepping groove 7 is provided on the bottom of the front side of the L-shaped plate 6, and a support and reset assembly 8 is fixedly connected to the top of both sides of the L-shaped plate 6.

[0023] refer to Figure 1 The support reset assembly 8 includes an extension block 81. The inner side of the extension block 81 is fixedly connected to the top of both sides of the L-shaped plate 6. A spring 82 is fixedly connected to the bottom of the extension block 81. The other end of the spring 82 is fixedly connected to the top of the first bracket 1. A limit assembly 9 is fixedly connected to the bottom of the extension block 81.

[0024] As a technical optimization of this utility model, by setting up a support and reset component 8, when the user applies downward pressure to the L-shaped plate 6 through the foot groove 7, the extension block 81 descends together with the L-shaped plate 6, and the spring 82 is compressed, deformed and generates a rebound force. Then, when the user releases the pressure on the foot groove 7, the L-shaped plate 6 quickly and automatically resets through the rebound force of the spring 82 and the cooperation of the extension block 81. Furthermore, before the power pipe is inserted into the fixing ring 3, the L-shaped plate 6 will not interfere with the insertion of the power pipe, thereby improving the user's ease of operation.

[0025] refer to Figure 1 and Figure 2 The limiting component 9 includes a straight rod 91, the top of which is fixedly connected to the bottom of the extension block 81. Limiting grooves 92 are provided on both sides of the top of the first bracket 1. The surface of the straight rod 91 is slidably connected to the inner wall of the limiting groove 92. The straight rod 91 is located inside the spring 82.

[0026] As a technical optimization of this utility model, by setting a limiting component 9, when the extension block 81 descends together with the L-shaped plate 6, causing the spring 82 to be compressed and deformed to generate a rebound force, the straight rod 91 moves with the extension block 81 and slides in the limiting groove 92 to constrain the deformation of the spring 82, thereby preventing the spring 82 from twisting during the deformation process and causing its rebound force to fail to be released normally, thus improving the stability when the L-shaped plate 6 is automatically raised and reset by using the rebound force of the spring 82.

[0027] refer to Figure 2 The bottom of the straight rod 91 is fixedly connected to an anti-detachment block 10, and the top of the anti-detachment block 10 is in contact with the bottom of the first bracket 1.

[0028] As a technical optimization of this utility model, by setting an anti-detachment block 10, during the process of the spring 82 pushing the extension block 81 and the L-shaped plate 6 to rise and reset, when the straight rod 91 slides along the trajectory of the limiting groove 92 to a certain distance, the anti-detachment block 10 will collide with the first bracket 1 accordingly, so that the spring 82's rebound force can no longer push the L-shaped plate 6 to rise, thereby preventing the explosive force generated at the moment of release of the spring 82's rebound force from directly pulling the straight rod 91 out of the limiting groove 92, causing the straight rod 91 and the limiting groove 92 to be unable to be used smoothly and repeatedly.

[0029] refer to Figure 1 and Figure 2 An adapter plate 11 is fixedly connected to the rear side of the bottom of the L-shaped plate 6. The bottom of the adapter plate 11 is set in an inverted V shape.

[0030] As a technical optimization of this utility model, by setting the adapter plate 11, when the L-shaped plate moves downward to contact the power pipe, the inverted V-shaped adapter plate 11 can fit the arc-shaped outer surface of the power pipe and squeeze and fix the power pipe from both sides. Compared with the planar contact, the inverted V-shaped structure can better adapt to the shape of the power pipe, thereby enhancing the effect of fixing the power pipe.

[0031] refer to Figure 3 The bottom of the adapter plate 11 is fixedly connected to a resistance-increasing pad 12, which is made of rubber.

[0032] As a technical optimization of this utility model, by setting a friction-increasing pad 12, when the adapter plate 11 contacts the power pipe, the rubber friction-increasing pad 12 replaces the adapter plate 11 and fits tightly with the power pipe. Due to the high friction characteristics of rubber, when the power pipe is subjected to external forces such as cutting force, the friction-increasing pad 12 can provide sufficient friction to resist these external forces and maintain the fixed state of the power pipe.

[0033] refer to Figure 1 The L-shaped plate 6 has expansion plates 13 fixedly connected to the bottom of both the front and back sides.

[0034] As a technical optimization of this utility model, by setting an expansion plate 13, when the user applies downward pressure to the L-shaped plate 6 through the foot groove 7, the expansion plate 13 increases the contact area between the user's foot and the foot groove 7, thereby making it easier for the user to have a better point of force to apply downward pressure to the L-shaped plate 6, thus improving the user's work efficiency.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to cut the power pipe, first insert the power pipe one by one into the two fixing rings 3, then control the cutting distance, and then apply downward pressure to the L-shaped plate 6 through the stepping groove 7, causing the L-shaped plate 6 to drive the adapter plate 11 to descend. Then, the extension block 81 descends together with the L-shaped plate 6, and the spring 82 is compressed and gradually deforms. At this time, the straight rod 91 moves with the extension block 81 and slides in the limiting groove 92, constraining the deformation of the spring 82, thus making the spring 82 stably upright. The expansion and contraction of the spring generates a rebound force, which in turn stabilizes the adapter plate 11 and presses it against the power tube. This allows the power tube to be quickly fixed by external force. The user then continues to press on the foot groove 7 and starts the cutting device 4 to cut the power tube. After the cutting is completed, the user can release the foot groove 7, which releases the rebound force of the spring 82 and quickly pushes the extension block 81 and the L-shaped plate 6 to rise and reset. At this point, the power tube can be quickly replaced. The above operation can be repeated to quickly cut a large number of power tubes, thus providing the advantage of quick fixation.

[0036] In summary, this power pipe cutting device for power construction, by setting up an L-shaped plate 6, allows the user to pull the L-shaped plate 6 downwards by stepping on the groove 7 after inserting the power pipe into the fixing ring 3. This causes the support and reset component 8 to retract, pressing the L-shaped plate 6 against the power pipe and quickly fixing it with external force. Finally, the cutting device 4 can be activated to cut the power pipe. This solves the problem that although the power pipe can be fixed by tightening the bolt to drive the fastening plate against the power pipe after it is inserted into the fixing ring, which is very time-consuming when cutting a large number of power pipes, thus reducing the efficiency of power pipe replacement and the cutting supply efficiency.
