Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically a mobile pipeline cutting machine. Background Technology

[0002] Water supply pipelines often need to cross various existing structures, such as roads, bridges, and building foundations. Trenchless or micro-excavation methods will be used, employing techniques such as rock and soil drilling, to ensure that water supply pipelines can safely and efficiently cross various structures without affecting surface traffic and the surrounding environment. With the continuous development of urban underground space, the demand for water supply pipelines to cross existing structures is also increasing. Therefore, when pipelines are to cross, they need to be cut according to their length, which requires the use of a fixed cutting machine.

[0003] A pipe cutting machine disclosed in patent publication number CN219617878U includes a second through hole and a first through hole. In use, one end of the pipe to be cut is placed against the clamping seat, and at this time, each clamping block is located inside the pipe. The telescopic cylinder is activated and drives the abutment column into the second through hole and the first through hole. The abutment column enters the first through hole and, through the cooperation between the cone part and the inclined waist of each clamping block, causes each clamping block to overcome the force of the corresponding return spring and move synchronously along the corresponding movable groove away from the axis of the first through hole. At this time, each clamping block achieves internal support and clamping of the pipe. After the cutting is completed, the telescopic cylinder controls the abutment column to retract to the initial position, and each clamping block retracts to the prompting position due to the release of the stored energy of the return spring, and the clamping of the pipe is canceled.

[0004] When the above-mentioned device cuts pipes, the pipes first need to be manually moved to a fixed platform, and then the position needs to be repeatedly adjusted and fixed before the cutting operation can be carried out. After the cutting is completed, the pipes need to be manually moved, which increases the labor intensity of workers, affects the cutting efficiency, and has poor flexibility. In order to address the above problems, a mobile pipe cutting machine is proposed. Utility Model Content

Detailed Implementation

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] 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.

[0026] Please see Figures 1-5In this embodiment, a mobile pipe cutting machine includes two sets of support columns 101 and a fixed block 102 installed on the top of the two sets of support columns 101. The two sets of support columns 101 are slidably connected to a positioning block 103 on the side that is close to each other. A first sprocket 104 is rotatably connected to the positioning block 103. A moving component for driving the positioning block 103 to slide is installed on the fixed block 102.

[0027] A movable groove 113 is provided on one side of the fixed block 102. Two sets of movable plates 112 are slidably connected in the movable groove 113. A second sprocket 111 is rotatably connected to the movable plate 112. A third motor 118 for driving the second sprocket 111 to rotate is installed on one set of the movable plates 112. A drive assembly for driving the two sets of movable plates 112 to slide is installed on the fixed block 102.

[0028] The same set of cutting chains 110 are rotatably connected to the two sets of second sprockets 111 and first sprockets 104.

[0029] In practical use, the total length of the 110-meter chain must meet the requirement of being an integer multiple of the chain links under different spans.

[0030] The moving component includes a guide groove 106 and a guide block 105. The guide groove 106 is formed on one side of the support column 101. A positioning block 103 is fixedly connected to one side of the guide block 105. The guide block 105 is slidably connected within the guide groove 106. A first threaded rod 107 is rotatably connected within the guide groove 106. The first threaded rod 107 is threadedly connected to the guide block 105. One end of the first threaded rod 107 extending to the outside is fixedly connected to a rotating wheel 108. Two sets of rotating wheels 108 are connected by a conveyor belt. A first motor 109 is installed on the fixed block 102 to drive a set of rotating wheels 108 to rotate. When the first motor 109 starts working, it drives a set of rotating wheels 108 to rotate. A set of rotating wheels 108 drives another set of rotating wheels 108 to rotate via a conveyor belt. The rotating wheels 108 drive the first threaded rod 107 to rotate. As the first threaded rod 107 rotates, the guide block 105 drives the positioning block 103 to move downward in the guide groove 106, which can drive the cutting chain 110 to move downward to cut the pipe.

[0031] The drive assembly includes two sets of positioning plates 114, which are fixedly connected to one side of the fixed block 102. A second threaded rod 116 is rotatably connected between the two sets of positioning plates 114. A moving block 115 is fixedly connected to the bottom of the moving plate 112. The moving block 115 is threadedly connected to the second threaded rod 116. A second motor 117 for driving the second threaded rod 116 to rotate is installed on one side of each set of positioning plates 114. The two sets of threads on the second threaded rod 116, corresponding to the moving block 115, have opposite directions of rotation. When the second motor 117 operates, it drives the second threaded rod 116 to rotate, causing the two sets of moving blocks 115 to move the moving plate 112 closer to each other in the moving groove 113. By setting the second threaded rods 116 with opposite directions of rotation, it can be ensured that the two sets of second sprockets 111 move synchronously when the spacing is adjusted, reducing the uneven force on the cutting chain 110.

[0032] The bottom of the support column 101 is fixedly connected to a fixing plate, and several sets of casters are installed on the bottom of the fixing plate.

[0033] Both the guide block 105 and the guide groove 106 have T-shaped cross sections. By setting the T-shaped guide block 105 and guide groove 106, the positioning block 103 can slide more stably.

[0034] The cross-section of the moving groove 113 and the moving plate 112 is cross-shaped. By setting the cross-shaped moving groove 113 and the moving plate 112, the moving plate 112 can move more stably.

[0035] The working principle of this utility model is as follows: In use, the support column 101 is first moved to the location of the pipe to be cut, so that the cutting chain 110 is positioned above the pipe. The third motor 118 then starts working, driving the second sprocket 111 to rotate, causing the cutting chain 110 to rotate on the second sprocket 111 and the first sprocket 104. The first motor 109 then starts working, driving a set of rotating wheels 108 to rotate. One set of rotating wheels 108 drives another set of rotating wheels 108 to rotate via a conveyor belt. The rotating wheels 108 drive the first threaded rod 107 to rotate. As the first threaded rod 107 rotates, the guide block 105 moves the positioning block 103 downward within the guide groove 106. The cutting chain is changed by the moving component. The bottom height of the cutting chain 110 can be adjusted by changing the sag of the cutting chain 110 to control the tension. At the same time, the second motor 117 works to drive the second threaded rod 116 to rotate, causing the two sets of moving blocks 115 to move the moving plate 112 closer to each other in the moving groove 113. The distance between the two sets of second sprockets 111 can be adjusted to change the lateral span and meshing angle of the cutting chain 110. It is necessary to ensure that the number of meshing teeth between the cutting chain 110 and the second sprockets 111 remains unchanged. The distance adjustment between the two sets of second sprockets 111 can simultaneously compensate for the length of the cutting chain 110 when adjusting the distance. During the downward movement of the positioning block 103, the cutting chain 110 rotates to cut the pipe, reducing the trouble of personnel handling, improving cutting efficiency, increasing flexibility, and facilitating pipe cutting.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
