Description

Technical Field

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

[0002] With the rapid development of modern urban construction and power engineering, PVC power pipes, as a type of pipe widely used in power cable protection, communication line laying and other fields, are seeing an increasing number of applications and varieties. Among the many PVC power pipe products, rectangular PVC power pipes are favored in some specific engineering scenarios due to their unique structural advantages, such as better space utilization efficiency and ease of installation and fixing.

[0003] Traditional PVC power pipe cutting devices are mostly designed and optimized for round pipes. When faced with rectangular PVC power pipes, traditional cutting devices reveal many limitations. The geometry of rectangular pipes differs significantly from that of round pipes, with sharp edges and flat surfaces. Existing clamping structures suitable for round pipes cannot effectively and stably clamp rectangular pipes. During the cutting process, rectangular PVC power pipes are prone to shaking, displacement, or even flipping. This not only seriously affects the cutting accuracy and quality, resulting in large dimensional deviations and uneven cuts that fail to meet engineering installation requirements, but also may cause safety hazards and damage to operators and equipment. Therefore, we propose a PVC power pipe cutting device. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a PVC power pipe cutting device, including a cutting table 1, a fixed plate 3 connected to the upper end of the cutting table 1 via a moving component 2, a through hole 301 through the side end of the fixed plate 3, a fixed ring 4 fixedly installed on the side end of the fixed plate 3, an opening on one side of the fixed ring 4, an annular groove 41 at the bottom end of the fixed ring 4, an internal gear 7 slidably connected in the annular groove 41, the internal gear 7 having a T-shaped cross-section, a plurality of rotating rods 10 rotatably installed on the side end of the fixed plate 3, a gear 6 fixedly connected to one end of the plurality of rotating rods 10, the plurality of gears 6 meshing with the internal gear 7, the plurality of gears 6 meshing with strip toothed plates 11, clamping blocks 8 fixedly installed on the opposite sides of the plurality of strip toothed plates 11, each clamping block 8 connected to the fixed plate 3 via a limiting member 9, a pushing component 12 provided on the side end of the fixed plate 3, a bracket 13 fixedly installed on the upper end of the cutting table 1, and a cutting machine 15 provided on the upper end of the bracket 13.

[0020] In an optional embodiment: each limiting member 9 includes a limiting groove 901 and a limiting slide rod 902. The limiting groove 901 is formed on the side end of the fixing plate 3, and the limiting slide rod 902 is slidably connected in the limiting groove 901. The side end of the limiting slide rod 902 is fixedly installed on the side end of the clamping block 8. The cross-section of the limiting groove 901 and the cross-section of the limiting slide rod 902 are both convex.

[0021] It should be noted that the limiting slide bar 902 mainly serves to support the clamping block 8 and can move within the limiting groove 901. The convex shape ensures that the limiting slide bar 902 can only move linearly within the limiting groove 901 and will not leave the limiting groove 901, thus playing a limiting role.

[0022] In an optional embodiment: the pushing assembly 12 includes a T-shaped rod 122, which is fixedly installed on the side of the fixing plate 3. A collar 121 is sleeved on the outer surface of the T-shaped rod 122. A cylinder 123 is fixedly installed on the outer surface of the collar 121. A collar 125 is fixedly installed on the telescopic end of the cylinder 123. A T-shaped rod 126 is provided inside the collar 125. A connecting plate 124 is fixedly installed at the bottom end of the T-shaped rod 126. The connecting plate 124 is fixedly installed on the outer surface of the internal gear 7.

[0023] It should be noted that the extension or retraction of the cylinder 123 causes the position of the collar 125, the T-shaped rod 126 and the connecting plate 124 to change, thereby allowing the internal gear 7 installed on the side of the connecting plate 124 to rotate clockwise and counterclockwise. Through the action of the gear 6 and the strip toothed plate 11, the position of the multiple clamping blocks 8 changes, thereby completing the clamping of the power tube.

[0024] In an optional embodiment: the moving component 2 includes a moving groove 201, which is formed at the upper end of the cutting table 1. A plurality of limiting rods 202 are fixedly installed on the inner wall of the moving groove 201. A sliding plate 204 is slidably connected to the outer surface of the plurality of limiting rods 202. The sliding plate 204 is fixedly installed at the bottom end of the fixed plate 3. A hydraulic rod 203 is fixedly installed at the side end of the sliding plate 204. One end of the hydraulic rod 203 is fixedly installed at the side end of the moving groove 201.

[0025] It should be noted that the extension or retraction of the hydraulic rod 203 can drag the sliding plate 204 to the left or right, thereby causing the fixed plate 3 installed on the upper end of the sliding plate 204 to move left or right, thus adjusting the clamping position.

[0026] In an optional embodiment: a waste collection box 14 is provided at the upper end of the cutting table 1, and the waste collection box 14 is located directly below the cutting machine 15.

[0027] It should be noted that cutting PVC power pipes generates a large amount of waste. If it is not collected in time, the waste will be scattered all over the ground, which not only affects the aesthetics of the workplace, but may also mix into other equipment or materials, affecting their normal use. The waste collection bin 14 facilitates the unified treatment of the collected waste.

[0028] In an optional embodiment, there are two fixed plates 3 and two moving components 2, which are arranged symmetrically and located on both sides of the cutting machine 15.

[0029] It should be noted that clamping both ends can keep the power pipe in a stable position and posture during the cutting process, avoiding deviations in cutting dimensions due to shaking or displacement. It can also prevent the pipe from accidentally popping out or rolling during the cutting process, thereby avoiding injury to the operator.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] A rectangular power tube is passed through the through hole 301. Then, by activating the cylinder 123, the output end of the cylinder 123 extends or retracts, which can change the position of the T-shaped rod 126 and the connecting plate 124. When the connecting plate 124 moves up or down, it will cause the internal gear 7 to rotate clockwise and counterclockwise. While the internal gear 7 rotates, it will cause the gear 6 that meshes with it to rotate in both directions. The clockwise and counterclockwise rotation of the gear 6 will cause the strip toothed plate 11 with its core to move left and right, which will further cause the clamping block 8 installed on the side of the strip toothed plate 11 to move. When multiple clamping blocks 8 move, they move in close contact with each other, which plays a restrictive role. In this way, the space between multiple clamping blocks 8 can be adjusted, thereby completing the clamping of rectangular power tubes of different diameters. By setting the moving component 2, the left and right positions of the fixing plate 3 can be adjusted, so as to better clamp according to the length of the rectangular tube and adjust the cutting position of the rectangular tube. The teeth of the internal gear 7, the teeth of the gear 6 and the teeth of the strip toothed plate 11 are all compatible.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
