Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, and more specifically, to a welding device for rainwater and sewage pipes. Background Technology

[0002] Due to their corrosion resistance, aging resistance, light weight, and environmental friendliness, plastic pipes are gradually replacing sewage pipe networks made of concrete pipes. During construction, plastic pipes are first arranged according to the distribution of the ditch. Then, a welding device is used to weld adjacent plastic pipes together. The welding device includes a welding machine body, a cutter head, a welding disc, and a support. When not in use, the cutter head and welding disc are placed on the support. When welding plastic pipes, the ends of adjacent plastic pipes are fixed to the welding machine body. The cutter head is used to cut and flatten the ends of the plastic pipes, and then the welding disc is used to melt the flattened ends. The welding machine body then joins the molten ends of the two plastic pipes together and applies pressure, thus completing the plastic pipe welding operation.

[0003] The cutter head rotates at high speed on the welding machine body, and is suspended from a crossbar within the machine body solely by its own weight. The stability of the welding machine body on the ground largely determines the flatness of the cutter head's cutting. During construction, due to uneven ground, it is necessary to insert individual blocks into the depressions, resulting in low welding efficiency. Therefore, there is an urgent need for a welding device that can quickly level the ground and maintain the balance of the welding machine body. Utility Model Content

[0004] The purpose of this utility model is to provide a welding device for rainwater and sewage pipes to solve the above-mentioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A welding device for rainwater and sewage pipes includes a welding machine body. The welding machine body includes a frame and a movable pipe clamp, a stationary pipe clamp, and a driver installed on the frame. The stationary pipe clamp is fixed to one end of a slide rod on the frame. The movable pipe clamp is movably installed on the slide rod, and the distance between the movable pipe clamp and the stationary pipe clamp is controlled by the driver. A ground-falling pipe is provided at the bottom of the frame. A soil-breaking mechanism is provided on the ground-falling pipe. The soil-breaking mechanism includes a soil-breaking component. The soil-breaking component is placed inside the ground-falling pipe, and its top protrudes above the ground-falling pipe. The bottom wall of the ground-falling pipe is composed of two symmetrically arranged elastic plates. When the soil-breaking component moves downward, its cutting edge passes through the space between the two elastic plates to break the soil layer below the ground-falling pipe, and the two elastic plates abut against the two sides of the soil-breaking component respectively.

[0007] Preferably, the earth-breaking component includes a cutting plate and a pressing platform. The cutting plate is installed inside the ground pipe, and the pressing platform is fixed to the top of the cutting plate and extends upward through the top wall of the ground pipe. The cross-section of the cutting plate is triangular, with the lower cone serving as the cutting edge. The maximum width of the cutting plate is slightly smaller than the inner width of the ground pipe.

[0008] Preferably, the soil-breaking mechanism further includes a side-cutting member, which is used to be inserted on the outer side wall of the ground pipe, and in this state, the bottom wall of the side-cutting member is flush with the bottom wall of the ground pipe.

[0009] Preferably, the side-cutting member is configured as a right-angled trapezoid, with an insertion block on its right-angled waist, and a slot for inserting the insertion block is provided on the outer wall of the ground pipe, and a permanent magnet is installed on the side-cutting member.

[0010] Preferably, a through pin hole is provided on the side wall of the ground pipe, and a through hole is provided on the cutting plate. A detachable pin is inserted into both the pin hole and the through hole.

[0011] Preferably, the cutting edge of the cutting plate is set to a concave arc shape.

[0012] Preferably, a limiting block is provided on the pressing platform, and the limiting block is spaced apart from the cutting plate.

[0013] The beneficial effects of this utility model are: the soil breaking component can extend and retract inside the ground pipe. When the welding machine body is placed on the uneven ground of the groove, the soil breaking component is pressed down so that it extends from the bottom of the ground pipe. The cutting edge on the soil breaking component breaks the ground, thereby pressing down the raised part of the welding machine body, so as to keep the welding machine body stable and reduce shaking when the cutter head cuts the pipe.

[0022] according to Figure 1-4 As shown, a welding device for rainwater and sewage pipes includes a welding machine body 1. The welding machine body 1 includes a frame 11 and a movable pipe clamp 12, a stationary pipe clamp 13, and a driver 14 mounted on the frame 11. The stationary pipe clamp 13 is fixed to one end of a slide rod 111 on the frame 11. The movable pipe clamp 12 is movably mounted on the slide rod 111, and the distance between the movable pipe clamp 12 and the stationary pipe clamp 13 is controlled by the driver 14. A ground pipe 112 is provided at the bottom of the frame 11. A soil-breaking mechanism 2 is provided on the 12. The soil-breaking mechanism 2 includes a soil-breaking component 21, which is placed inside the grounding pipe 112 and its top protrudes above the grounding pipe 112. The bottom wall of the grounding pipe 112 is composed of two symmetrically arranged elastic plates 1121. When the soil-breaking component 21 moves downward, its cutting edge passes through the space between the two elastic plates to break the soil layer below the grounding pipe 112, and the two elastic plates 1121 abut against the two sides of the soil-breaking component 21. The soil-breaking component 21 includes a cutting plate 211 and a pressing platform 212. The cutting plate 211 is installed inside the grounding pipe 112, and the bottom end of the pressing platform 212 is fixedly connected to the top end of the cutting plate 211. The top end of the pressing platform 212 passes through the top wall of the grounding pipe 112 and extends upward. The cross-section of the cutting plate 211 is triangular, with its lower cone serving as the cutting edge. The maximum width of the cutting plate 211 is slightly smaller than the inner width of the grounding pipe 112.

[0023] according to Figure 1-4 As shown, the soil-breaking component 21 is retractable inside the ground-falling pipe 112. When the welding machine body 1 is placed on the uneven ground, the soil-breaking component 21 is pressed down so that it extends from the bottom of the ground-falling pipe 112. The cutting edge on the soil-breaking component 21 breaks the ground, thereby pressing down the raised part of the welding machine body 1, so as to keep the welding machine body 1 stable and reduce shaking when the cutter head cuts the pipe.

[0024] according to Figure 1-4 As shown, the soil-breaking mechanism 2 also includes a side-cutting member 22, which is used to be inserted into the outer wall of the ground pipe 112, and in this state, the bottom wall of the side-cutting member 22 is flush with the bottom wall of the ground pipe 112. The side-cutting member 22 is configured as a right-angled trapezoid, and an insertion block 221 is provided on its right-angled waist. The insertion block 221 is set at the middle and slightly above the height of the side-cutting member 22, and the cutting edge of the side-cutting member 22 is lower than the height of the insertion block 221. When cutting the soil horizontally, the side-cutting member 22 is prevented from tilting upward. A slot for the insertion block 221 is opened on the outer wall of the ground pipe 112, and a permanent magnet 222 is installed on the side-cutting member 22.

[0025] according to Figure 1-4 As shown, a through pin hole is provided on the side wall of the ground pipe 112, and a through hole is provided on the cutting plate 211. A detachable pin 3 is inserted into both the pin hole and the through hole. The cutting edge of the cutting plate 211 is set with a concave arc shape, which can better cut into the soil. A limit block is provided on the pressing table 212, and the limit block is set at intervals with the cutting plate 211. There are two through holes on the cutting plate 211, which are distributed on the same vertical line. When the pin 3 is inserted into the lower through hole, it is used to prevent the cutting plate 211 from shaking in the ground pipe 112. When the pin 3 is inserted into the upper through hole, the lower part of the cutting plate 211 protrudes out of the ground pipe 112, which is used to restrict the cutting plate 211 from retracting into the ground pipe 112. At this time, an external force can be applied to the breaking component 21 or the welding machine body 1 can be lifted. The impact force generated by the falling of the welding machine body 1 under its own weight can be used to break the ground component 21.

[0026] according to Figure 1-4 As shown, the soil-breaking mechanism 2 is most suitable for use on slightly soft soil. The soil-breaking component 21 is used to break the soil below the ground pipe 112, and the side-cutting component 22 is used to level the soil when the rotating frame 11 is used. The soil-breaking component 21 and the side-cutting component 22 are combined, and the appropriate leveling method is selected according to the construction environment. The two elastic plates 1121 are initially used to hold the cutting plate 211 from falling from the ground pipe 112. As the cutting plate 211 is pressed down, it deforms and bends into an arc shape on both sides of the cutting plate 211, which facilitates the diversion of the broken soil to both sides.
