[0002] Sewage pipelines are an important part of urban infrastructure. Sewage pipelines shoulder the important task of transporting and collecting urban rainwater and sewage. The management of urban sewage pipelines is of great significance to urban environmental protection, urban construction and economic development. The sewage pipeline system consists of pipelines for collecting and transporting urban sewage and their ancillary structures. When laying existing sewage pipelines, a crane is often used to lift the pipelines to be laid, and then the sewage pipelines to be laid are placed into a pre-dug pit by the crane, thus completing the laying of the sewage pipelines. However, this laying method requires frequent movement of the crane, and the crane needs to extend and piston support arms, and the operation is very time-consuming, which slows down the laying speed of the sewage pipelines. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a sewage pipeline laying device, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a sewage pipeline laying device, including a gantry crane, moving mechanisms are arranged at the lower parts of the left and right sides of the gantry crane, an adjusting mechanism is arranged at the output end of the gantry crane, and two grasping mechanisms are arranged at the lower part of the adjusting mechanism;

[0005] The moving mechanism includes a bracket, two load-bearing wheels, a crawler belt and a reduction motor. The middle parts of the load-bearing wheels are rotatably connected to the inner parts of the front and rear sides of the bracket. The reduction motor is installed on the outer side of the bracket.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] As Figures 1-5 shown, a sewage pipeline laying device includes a gantry crane 1. Moving mechanisms 2 are arranged at the lower parts on the left and right sides of the gantry crane 1. An adjusting mechanism 3 is arranged at the output end of the gantry crane 1. Two grasping mechanisms 4 are arranged at the lower part of the adjusting mechanism 3.

[0021] In this embodiment, the moving mechanism 2 includes a support 201, two load-bearing wheels 202, a crawler belt 203 and a reduction motor 204. The middle parts of the load-bearing wheels 202 are rotatably connected to the inner parts on the front and rear sides of the support 201. The reduction motor 204 is installed on the outer side of the support 201. The output end of the reduction motor 204 penetrates through the wall of the support 201 and is fixedly connected to the outer circumference of one of the load-bearing wheels 202. The two ends inside the crawler belt 203 are meshed and connected to the outer circumference of the load-bearing wheels 202. The upper part of the support 201 is installed at the lower parts on the left and right sides of the gantry crane 1. The adjusting mechanism 3 includes a steel wire rope 301, two connecting plates 302, two limiting rods 303, a double-threaded different-pitch screw rod 304 and a servo motor I 305. The front and rear ends of the limiting rods 303 are fixedly connected to the left and right sides of the connecting plates 302. The front and rear ends of the double-threaded different-pitch screw rod 304 are rotatably connected to the middle parts of the connecting plates 302. The servo motor I 305 is installed on the outer side of one of the connecting plates 302. The output end of the servo motor I 305 penetrates through the connecting plate 302 and is fixedly connected to the front and rear ends of the double-threaded different-pitch screw rod 304. The middle parts on the upper sides of the grasping mechanisms 4 are threadedly connected to the front and rear sides of the double-threaded different-pitch screw rod 304. The left and right sides of the grasping mechanisms 4 are slidably connected to the outer circumferences of the limiting rods 303. The two ends of the steel wire rope 301 are fixedly connected to the upper parts of the connecting plates 302. The middle part of the steel wire rope 301 is fixedly connected to the output end of the moving mechanism 2.

[0022] Specifically, drive the reduction motor 204 to rotate the load wheel 202 connected thereto. Through the cooperation of another load wheel 202, the crawler 203 rotates, so that the moving mechanism 2 can move back and forth. By controlling the forward and reverse rotation and speed of the reduction motor 204, the device can be controlled to move forward, backward, left and right, which is convenient for quickly laying sewage pipes. At the same time, drive the first servo motor 305, and limit the grasping mechanism 4 through the limiting rod 303. When the bidirectional different-thread screw rod 304 rotates, the grasping mechanism 4 will approach or separate from each other, so as to adapt to sewage pipes of different lengths.

[0023] In this embodiment, the grasping mechanism 4 includes a second servo motor 401 and two grasping components 402. The two grasping components 402 are arranged in mirror image. The second servo motor 401 is installed on one side of the upper part of one of the grasping components 402. The grasping component 402 includes a gear 4021, a toothed ring 4022 and a housing 4023. The outer circumference of the toothed ring 4022 is slidably connected to the lower part of the housing 4023. The middle part of the gear 4021 is rotatably connected to the middle part of the housing 4023. The lower part of the gear 4021 meshes with the upper part of the toothed ring 4022. The middle part of the upper side of the housing 4023 is threadedly connected to the outer circumference of the bidirectional different-thread screw rod 304. The left and right sides of the upper part of the housing 4023 are slidably connected to the outer circumference of the limiting rod 303. The second servo motor 401 is installed on one side of the housing 4023. The output end of the second servo motor 401 penetrates through the wall shells of the two housings 4023 and is fixedly connected to the middle parts of the two gears 4021. The toothed ring 4022 is a circle. A limiting groove 4024 is formed in the middle of the toothed ring 4022. The limiting groove 4024 is slidably connected to the outer circumference of the limiting strip 4025. One side of the limiting strip 4025 is fixedly connected to the front and rear sides of the middle part of the housing 4023.

[0024] Specifically, the movement range of the toothed ring 4022 is restricted by the limiting strip 4025 and the limiting groove 4024. Drive the second servo motor 401 to make the gear 4021 drive the toothed ring 4022 to rotate and extend out of the housing 4023. Since the grasping components 402 are arranged in mirror image, the housing 4023 and the two toothed rings 4022 form a ring. The ring formed by the two grasping components 402 can quickly and stably lift the sewage pipe to move, which is convenient for laying.

[0025] Working principle:

[0026] The movement range of the gear ring 4022 is restricted by the limiting strip 4025 and the limiting groove 4024. The second servo motor 401 is driven to make the gear 4021 drive the gear ring 4022 to rotate and extend out of the housing 4023. Since the grasping assemblies 402 are arranged in a mirror image, the housing 4023 and the two gear rings 4022 form a circular ring. The circular ring formed by the two grasping assemblies 402 can quickly and stably lift the sewage pipe for movement, which is convenient for laying. The reduction motor 204 is driven to make the load-bearing wheels 202 connected thereto rotate. With the cooperation of the other load-bearing wheel 202, the crawler 203 rotates, so that the moving mechanism 2 can move back and forth. By controlling the forward and reverse rotation and the rotation speed of the reduction motor 204, the device can be controlled to move forward, backward, left and right, which is convenient for quickly laying the sewage pipe. At the same time, the first servo motor 305 is driven. The grasping mechanism 4 is restricted by the limiting rod 303. When the bidirectional different-thread screw rod 304 rotates, the grasping mechanisms 4 will approach or separate from each other, so as to adapt to sewage pipes of different lengths.
