Technical Field
[0001] This utility model relates to the technical field of pipeline laying devices, and in particular to a construction device for laying water supply and drainage pipelines under existing pipelines. Background Technology
[0002] Construction of existing water supply and drainage pipelines faces complex environments. For example, laying pipelines beneath existing ones is difficult without removing the existing ones, impacting efficiency. Furthermore, pipelines beneath existing ones are often unstable during installation, potentially leading to misalignments and gaps at joints. Additionally, the lack of support for the existing pipelines during construction compromises safety. Removing the existing pipelines and then repairing them after completion increases overall construction costs, requires complex procedures that delay progress, and causes inconvenience to nearby users.

The device can also replace appropriately sized arc-shaped clamping plates with bolts as needed. When docking two sections of water supply and drainage pipes, the docking drive assembly moves the two sections towards each other, automatically inserting one side of the pipe into the joint of the other side, thus completing the docking assembly and achieving precise docking. Construction can be carried out without dismantling existing pipelines, protecting them and improving assembly efficiency. The device is equipped with casters, a toolbox, and a collection drawer. The casters facilitate movement, while the toolbox and drawer allow for convenient storage of workers' tools, preventing loss.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] Reference Figure 1-4This utility model embodiment discloses a construction device for laying water supply and drainage pipes under existing pipes, which includes: a base 1, a toolbox 5 fixedly connected to the bottom end of the base 1, a collection drawer 6 slidably connected to the inner wall of the toolbox 5, handles 7 symmetrically fixedly connected to the left and right side walls of the base 1, four universal wheels 2 installed at the bottom end of the base 1, a docking drive assembly 3 provided on the base 1, two pipe clamping assemblies 4 symmetrically arranged front and rear connected to the docking drive assembly 3, and a limit groove 101 symmetrically opened on the left and right side walls of the base 1, with a support assembly 8 slidably arranged in the limit groove 101.
[0022] The docking drive assembly 3 includes a slide groove 301, which is formed on the upper surface of the base 1. A bidirectional threaded rod 302 is rotatably connected through the front and rear inner walls of the slide groove 301. A crank 304 is fixedly connected to one end of the bidirectional threaded rod 302. A symmetrically arranged displacement plate 303 is threadedly connected through the outer wall of the bidirectional threaded rod 302. The outer walls of the displacement plates 303 are slidably connected to the inner wall of the slide groove 301.
[0023] The pipe clamping assembly 4 includes a sliding plate 401. The bottom ends of the two sliding plates 401 are fixedly connected to the top ends of the displacement plate 303. The inner walls of the left and right sides of the sliding plate 401 are rotatably connected to a two-way threaded rod 402. One end of the two-way threaded rod 402 is fixedly connected to a crank handle 405. The outer walls of the handles of the crank handle 304 and the crank handle 405 are both fitted with sponge sleeves. The outer walls of the two-way threaded rod 402 are threadedly connected to symmetrically arranged displacement blocks 403. The outer walls of the displacement blocks 403 are slidably connected to the inner walls of the sliding plates 401. The side walls of the displacement blocks 403 are bolted with arc-shaped clamping plates 404. The two arc-shaped clamping plates 404 are symmetrically arranged on the left and right sides.
[0024] The support assembly 8 includes two sets of base plates 801 arranged symmetrically at the front and back. Each set of base plates 801 has two plates. The side walls of the two sets of base plates 801 are slidably connected to the inner walls of the two side limiting grooves 101 respectively. A hydraulic cylinder 802 is fixedly installed on the upper surface of each base plate 801. An arc-shaped support plate 803 is fixedly connected to the top of the movable rod of the hydraulic cylinder 802.
[0025] Before connecting two water supply and drainage pipes using the base 1, docking drive assembly 3, and pipe clamping assembly 4, the two sections of water supply and drainage pipes are clamped. During clamping, the water supply and drainage pipes are placed between two arc-shaped clamping plates 404. Turning the crank 405 drives the bidirectional threaded rod 402 to rotate, which, in conjunction with the sliding groove plate 401, limits the movement of two displacement blocks 403 towards each other until the two arc-shaped clamping plates 404 clamp the outer wall of the water supply and drainage pipes. This system is suitable for water supply and drainage pipes of different sizes, and the appropriate size arc-shaped clamping plates 404 can be replaced by bolts as needed. After clamping and fixing the water supply and drainage pipes on both sides, when connecting the two sections of water supply and drainage pipes, turning the crank 304 drives the bidirectional threaded rod 302 to rotate, which, in conjunction with the sliding groove 304... 1. The limit switch moves two displacement plates 303 towards each other, which in turn moves the pipe clamping components 4 on both sides and the water supply and drainage pipes, so that the water supply and drainage pipe on one side can be automatically inserted into the joint of the water supply and drainage pipe on the other side, thus completing the docking and assembly, achieving precise docking, and allowing construction without removing the existing pipelines, protecting the existing pipelines and improving assembly efficiency. The universal wheels 2, toolbox 5, and collection drawer 6 are provided. The universal wheels 2 facilitate the movement of the device, and the toolbox 5 and collection drawer 6 facilitate the storage of workers' tools to prevent tools from being lost. The support component 8 is provided. Before laying, the support component 8 can be slid out and laid separately. The hydraulic cylinder 802 is activated to push the arc-shaped support plate 803 upward to support the existing pipeline, improving the safety of construction.
[0026] Working principle: Before laying the water supply and drainage pipeline, place the pipeline below the existing pipeline. Slide out the support component 8 and lay it separately. Start the hydraulic cylinder 802 to push the arc-shaped support plate 803 upward to support the existing pipeline, improving construction safety. The water supply and drainage pipeline needs to be assembled by connection. Before connection, clamp the two sections of the pipeline separately. During clamping, place the pipeline between the two arc-shaped clamping plates 404. Turn the crank handle 405 to drive the bidirectional threaded rod 402 to rotate. This, combined with the limiting drive of the sliding plate 401, moves the two displacement blocks 403 towards each other until the two arc-shaped clamping plates 404 clamp the outer wall of the pipeline, thus clamping the pipeline on both sides. After fixing, when connecting the two sections of water supply and drainage pipes, turn the crank handle 304 to drive the bidirectional threaded rod 302 to rotate. In conjunction with the sliding groove 301, the two displacement plates 303 move towards each other, thereby driving the pipe clamping components 4 on both sides and the water supply and drainage pipes to move. This allows the water supply and drainage pipe on one side to automatically insert into the joint of the water supply and drainage pipe on the other side, thus completing the connection and assembly. This achieves precise connection and improves assembly efficiency. After assembly, use the external traction equipment to move the device in the trench and smoothly pass under the pipe. After laying, turn the crank handle 405 in the opposite direction to drive the two arc-shaped clamping plates 404 to move in opposite directions, thereby releasing the restriction on the water supply and drainage pipes and completing the disassembly of the device. The device can then be taken out.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
