Problems solved by technology

For some large-sized pipes, this kind of groove-shaped groove has insufficient bearing capacity due to the gap between the corner of the groove and the pipe, and the stability of the pipe is reduced.
If you want to open arc grooves, it is difficult to process manually, and there is no machine equipment that can open arc grooves

Embodiment 1

[0036] Embodiment 1: as Figure 1-Figure 3 As shown, the present invention comprises a speed reducer 11, a frame 15 and its upper connection transmission mechanism, a molding die 1, and at least three soil throwing wheels; end, the other soil throwing wheel is a deep soil throwing wheel 4, which is arranged in the rear row of the two front soil throwing wheels 5, and is positioned at the middle and lower position of the two front soil throwing wheels 5. Corresponding to the outer wall of the pipeline, each soil throwing wheel is connected to the reducer 11 through the transmission mechanism, and the forming mold 1 is set on the frame 15 behind the deep soil throwing wheel 4, and the front end of the forming mold 1 is placed on the deep soil throwing wheel 4 In the middle and lower part, the outer arc wall of the molding die 1 is matched with the outer wall of the pipe to be placed. During work, speed reducer 11 is driven by power machine, and the rotation direction of two fro...

Embodiment 2

[0041] Embodiment 2: The difference between this embodiment and Embodiment 1 is that when it is necessary to open a larger arc groove and install a large-diameter pipeline, a set is also provided between the rear column of the depth throwing wheel 4 and the forming die on the frame 15. There are two side by side symmetrical width throwing wheels 3. The width throwing wheel 3 and the front throwing wheel 5 and the depth throwing wheel 4 have the same structure; the arc formed by the two front throwing wheels, the depth throwing wheel and the outer circumference of the two width throwing wheels corresponds to the outer wall of the pipeline to be placed .

[0042]The angle α of the soil throwing sheet and the cone surface of the soil dividing plate in the throwing wheel described in this example is 80 °. The conical fan-shaped arc plate of the soil shovel blade 132 and the soil throwing cover 13 are arranged at an inclined angle, and the angle β between the bottom surface and th...

Embodiment 3

[0043] Embodiment 3: The difference between this embodiment and Embodiment 1 is that a rear earth throwing wheel 2 is provided at the other end of the frame 15 . The soil throwing wheel 2 removes the soil throwing cover 13 on the basis of other earth throwing wheels. Such as Figure 4 Shown, comprise rotating shaft 6, rear plate, soil dividing plate 27 and a plurality of throwing soil pieces 24 that are arranged in pairs, a plurality of throwing soil pieces 24 are evenly arranged on the back plate along the shaft sleeve 23 circumference of rotating shaft, adjacent two throwing soil There are soil-dividing boards 27 connected between the sheets 24, forming a frustum-shaped soil-dividing board as a whole. The soil-throwing sheet 24 is inclined to the conical surface of the soil-distributing plate 27, and the angle α between the soil-throwing sheet 24 and the conical surface of the soil-dividing plate 27 is 80-83°. The ends of the soil throwing tablets 24 are respectively blade...

Abstract

The invention discloses a pipe arc opening machine, and belongs to the technical field of a pipeline slotting device. The pipe arc opening machine comprises a speed reducer, a rack, a transmission mechanism, a forming die and at least three soil throwing wheels, wherein the transmission mechanism, the forming die and the at least three soil throwing wheels are connected to the rack, two front soil throwing wheels are symmetrically arranged at a working end of the rack in parallel, the other soil throwing wheel is a deep soil throwing wheel, the deep soil throwing wheel is arranged behind the two front soil throwing wheels and is positioned at the middle lower part of the two front soil throwing wheels, an arc shape formed by the peripheries of the three soil throwing wheels corresponds to the outer wall of a to-be-placed pipeline, each soil throwing wheel is connected with the speed reducer through the transmission mechanism, the forming die is arranged on the rack which is arranged behind the deep soil throwing wheel, a front-most working end of the forming die is arranged at the middle lower part of the deep soil throwing wheel, and the outer arc-shaped wall of the forming die is matched with the outer wall of the to-be-placed pipeline. According to the pipe arc opening machine disclosed by the invention, the excavation of an arc-shaped groove for placing a pipeline can be completed; the arc-shaped groove is matched with the outer wall of the pipeline, thus the supporting force of the pipeline is enhanced, and the labor intensity of a worker is reduced.

Description

technical field [0001] The invention belongs to the technical field of pipe slotting equipment, in particular to a pipe arc opening machine. Background technique [0002] At present, during pipeline construction, in order to install pipelines, the form of excavating trenches is generally adopted, and the trenches are generally grooved. For some large-sized pipelines, the groove-shaped groove has insufficient bearing capacity and reduced stability of the pipeline because of the gap between the corners of the groove and the pipeline. If you want to open the arc groove, it is difficult to process it artificially, and there is no machine equipment that can open the arc groove. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to provide a pipeline arc opening machine, which can excavate arc grooves for placing pipelines. [0004] The present invention comprises reducer, frame and its upper connect...
