Description

Technical Field

[0001] This invention relates to the field of sewage discharge pipelines, and more particularly to an auxiliary docking device for sewage discharge pipelines. Background Technology

[0002] Polyethylene pipe (PE pipe) is a type of pipe made of polyethylene material and is widely used in various fluid transportation fields.

[0003] Polyethylene pipes also have significant applications in sewage discharge. Multiple sections of polyethylene pipe are butt-jointed (two pipes are typically connected via a socket joint and then fixed by heat fusion) to form a complete piping system suitable for sewage discharge. For pipe connections, when making a splice, because the diameter difference between the two pipe ends is relatively small, the end of one pipe section needs to be expanded to facilitate the insertion of the other pipe section. This expansion requires first heat fusion of the pipe, softening it, and then using tools to expand the opening. After cooling, the pipe can be assembled by splicing.

[0004] However, the following defects and shortcomings still exist in the application implementation process: For underground pipelines, they are usually installed section by section. Therefore, the pipeline assembly work is carried out inside the pre-dug foundation pit. However, if the pipe ends are assembled by hot-melt processing, there are problems such as low assembly efficiency and high assembly difficulty.

[0005] Therefore, it is necessary to provide a new auxiliary docking device for sewage pipes to solve the above-mentioned technical problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides an auxiliary docking device for sewage pipes.

[0007] The auxiliary docking device for sewage pipes provided by the present invention includes: Base frame; Auxiliary pipe axial moving parts, which are in two sets and symmetrically installed on the base frame, are used to support the two pipe sections to be connected. The positioning tube is located between two sets of auxiliary pipe axial moving parts, and works with one set of auxiliary pipe axial moving parts to support and position the pipe that needs to be flared. A movable adjusting component, which is mounted on a base frame, includes a bracket that can be installed along the length of the base frame for mounting the positioning tube, and uses the bracket to drive the positioning tube to move axially. A pipe port pulling assembly, comprising multiple pipe port pulling assemblies, is installed on a positioning tube and arranged in a ring. Each pipe port pulling assembly includes a hook rod that can be inserted into the pipe along the port and pull the pipe radially to expand the pipe port outward.

[0008] Preferably, the base frame includes a fixed base frame and a first mounting frame located above the fixed base frame, both of which are rectangular and are connected and fixed by multiple support rods located at the corners.

[0009] Preferably, the auxiliary pipe axial moving component includes a second mounting bracket, which is bolted to the first mounting bracket at a position away from the center, and a support roller for mounting the pipe is rotatably connected to the second mounting bracket via a shaft.

[0010] Preferably, the diameter of the support roller decreases from both ends to the center.

[0011] Preferably, the positioning tube consists of two semi-cylinders, which are rotatably connected on one side by a hinge and fixed on the other side by a buckle.

[0012] Preferably, the movable adjustment component includes a fixed base, which is bolted to the upper end of the fixed base frame. A first hydraulic cylinder is fixed on the fixed base, and the telescopic end of the first hydraulic cylinder is along the length direction of the fixed base frame. A horizontally arranged mounting base is provided above the first mounting bracket, and a vertically telescopic second hydraulic cylinder is fixed to the upper end of the mounting base. The bracket is fixed to the telescopic end of the second hydraulic cylinder. A third mounting bracket is bolted to the center position of the lower end of the mounting base. The output end of the first hydraulic cylinder is fixed to the third mounting bracket to drive the mounting base to move horizontally. Two second sliding blocks are also symmetrically fixed at the lower end of the mounting base away from the center.

[0013] Preferably, a positioning plate arranged along the length direction is bolted to the first mounting bracket, and a linear rail is fixed on the positioning plate, while the second slide is mounted on the linear rail.

[0014] Preferably, the pipe port pulling assembly further includes a first hinge frame, which is welded and fixed to the outer circumference of the positioning pipe and near the end. A rotating arm is rotatably connected to the first hinge frame via a shaft. The rotating arm is L-shaped, with its long end extending toward the outer end of the positioning pipe opening, and the hook rod is welded and fixed to that end of the rotating arm. A second hinge frame is welded and fixed to the outer circumference of the positioning tube. A third hydraulic cylinder is rotatably connected to the second hinge frame. The telescopic end of the third hydraulic cylinder is rotatably connected to the short end of the rotating arm.

[0015] Preferably, the other end of the hook rod extends toward the inside of the positioning tube, so that a clamping groove for pipe insertion is formed between the hook rod and the rotating arm.

[0016] Compared with related technologies, the auxiliary docking device for sewage pipes provided by the present invention has the following advantages: 1. The positioning tube, together with the auxiliary pipe axial movement component, can support and position the pipe that needs to be flared. At the same time, the positioning tube has multiple pipe port pulling components. The pipe port can be hooked by the hook rod, and then the pipe wall can be pulled radially. The expansion of the port is achieved by relying on the flexibility of the pipe itself. Then, another section of pipe can be inserted into it, which can realize the plug-in installation of two sections of pipe, and further improve the efficiency of pipe assembly. 2. Two sets of auxiliary pipe axial moving parts are used to support the two pipe sections to be assembled. They have a positioning function for the pipes and can also assist in the movement of the pipes so that the ends of the two pipe sections are accurately aligned and the two pipe sections are easy to approach each other, thus reducing the difficulty of pipe docking and assembly.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 7 The present invention provides an auxiliary docking device for sewage pipes, which includes a base frame 1, an auxiliary pipe axial moving component 2, a positioning pipe 3, a moving adjusting component 4, and a pipe port pulling assembly 5.

[0022] For base frame 1; Please see Figure 3 The base frame 1 includes a fixed base frame 11 and a first mounting frame 12 located above the fixed base frame 11. Both are rectangular and are connected and fixed by multiple support rods 13 located at the corners. A positioning plate 14, which is arranged along the length direction, is bolted to the first mounting bracket 12. A linear rail 15 is fixed on the positioning plate 14, and the second slide 45 is mounted on the linear rail 15.

[0023] It should be noted that: the base frame 1 is the basic support structure of the entire device, which includes a fixed base frame 11 and a first mounting frame 12. Multiple support rods 13 are fixed at the upper corners of the fixed base frame 11. The support rods 13 are connected and fixed to the first mounting frame 12 to form a cuboid frame structure. Depending on the usage environment, different positioning support structures can be set at the lower end of the fixed base frame 11; If the sewage pipes are installed inside the building, a roller structure can be set at the lower end of the fixed base frame 11 to support the entire device and facilitate the transfer of the entire device. If used inside an excavated foundation pit, the fixed base frame 11 can be placed directly at the bottom of the pit. If the stability is insufficient due to the soft soil at the bottom of the pit, a ground insertion structure can be added to stabilize and fix the base frame 1.

[0024] The auxiliary pipeline axial moving component 2 has two sets, which are symmetrically installed on the base frame 1; Please see Figure 4The auxiliary pipe axial moving component 2 includes a second mounting bracket 21, which is bolted to the first mounting bracket 12 at a position away from the center. A support roller 22 for laying the pipe is rotatably connected to the second mounting bracket 21 via a shaft. The diameter of the support roller 22 decreases from both ends to the center.

[0025] It should be noted that there are two sets of auxiliary pipe axial moving parts 2. The two sets of auxiliary pipe axial moving parts 2 are used to support the two pipe sections to be inserted and fixed. Each set includes a second mounting frame 21, which is U-shaped and can be fixed to the first mounting frame 12 with bolts to ensure its stability. A support roller 22 is mounted on the first mounting frame 12 via a shaft. The support roller 22 is used to support the pipe. The diameter of the support roller 22 decreases from both ends to the center. Therefore, it can also play an auxiliary positioning role for the supported pipe, so that the two pipe sections can be nearly concentric, which makes the subsequent insertion and assembly more convenient and faster. The support roller 22 is mounted on the second mounting bracket 21 via a shaft and can rotate. Therefore, when the pipeline is displaced in the axial direction, the support roller 22 can assist the movement of the pipeline and provide certain convenience for the pipeline connection.

[0026] The positioning tube 3 is positioned between the two sets of auxiliary pipe axial moving parts 2, and works with one set of auxiliary pipe axial moving parts 2 to support and position the pipe that needs to be flared. Please see Figure 5 The positioning tube 3 consists of two semi-cylinders, which are connected by a hinge on one side and fixed by a buckle on the other side.

[0027] It should be noted that the positioning tube 3 is composed of two semi-cylinders connected by a hinge, so the positioning tube 3 can be opened. In the open state, it is convenient to place the pipe inside the positioning tube 3 and to remove the assembled positioning tube 3. The two semi-cylinders are also equipped with a snap-fit ​​structure. After the two are joined together to form a complete tube structure, they can be reinforced by snap-fit ​​to prevent them from separating.

[0028] For the movable adjustment component 4; Please see Figure 6 The movable adjustment component 4 includes a fixed base 41, which is bolted to the upper end of the fixed base frame 11. A first hydraulic cylinder 42 is fixed on the fixed base 41, and the telescopic end of the first hydraulic cylinder 42 is along the length direction of the fixed base frame 11. A horizontally arranged mounting base 43 is provided above the first mounting bracket 12. A vertically telescopic second hydraulic cylinder 46 is fixed to the upper end of the mounting base 43. A bracket 47 is fixed to the telescopic end of the second hydraulic cylinder 46. The positioning tube 3 is fixed to the bracket 47. A third mounting bracket 44 is bolted to the center of the lower end of the mounting base 43. The output end of the first hydraulic cylinder 42 is fixed to the third mounting bracket 44 to drive the mounting base 43 to move horizontally. Two second slide blocks 45 are also symmetrically fixed at the lower end of the mounting base 43 away from the center.

[0029] It should be noted that: in the movable adjustment component 4, the first hydraulic cylinder 42 is the main driving source for displacement drive. It is fixed to the fixed base frame 11 by the fixed seat 41, that is, it is located between the fixed base frame 11 and the first mounting frame 12. There is a mounting seat 43 above the first mounting frame 12. The third mounting frame 44, which is fixed at the lower end of the mounting seat 43, extends to the space between the fixed base frame 11 and the first mounting frame 12 and is fixed to the telescopic end of the first hydraulic cylinder 42. Thus, the first hydraulic cylinder 42 can be used to drive the mounting seat 43 to move. The mounting base 43 has a second hydraulic cylinder 46 at its upper end, and a bracket 47 is fixed at the upper end of the second hydraulic cylinder 46. The bracket 47 is used to fix the positioning tube 3. Therefore, when the mounting base 43 moves, it can drive the positioning tube 3 to move together. The second hydraulic cylinder 46 can drive the positioning tube 3 to move up and down. That is, when connecting two pipe sections, if there is a height difference between the two pipe sections, the positioning tube 3 can be adjusted to drive the end of one pipe section to move up and down, so that the correspondence between the two pipe sections can be more accurate. A slide 45 is also provided on the mounting base 43, and a positioning plate 14 is provided on the first mounting frame 12. A linear track 15 is provided on the positioning plate 14. The slide 45 is installed on the linear track 15, so that the slide 45 can provide further support to the mounting base 43 to improve its overall stability.

[0030] For pipe port tensioning assembly 5; Please see Figure 7 The pipe port pulling assembly 5 also includes a first hinge frame 51, which is welded and fixed to the outer circumference of the positioning tube 3 and near the end. A rotating arm 52 is rotatably connected to the first hinge frame 51 via a shaft. The rotating arm 52 is L-shaped, with the long end of the rotating arm 52 extending toward the outer end of the positioning tube 3, and the hook rod 53 is welded and fixed to this end of the rotating arm 52. A second hinge frame 55 is also welded and fixed to the outer circumference of the positioning tube 3. A third hydraulic cylinder 54 is rotatably connected to the second hinge frame 55. The telescopic end of the third hydraulic cylinder 54 is rotatably connected to the short end of the rotating arm 52. The other end of the hook rod 53 extends toward the inside of the positioning tube 3, so that a clamping groove for pipe insertion is formed between the hook rod 53 and the rotating arm 52.

[0031] It should be noted that there are multiple pipe port pulling components 5, which are arranged in a ring shape, thus enabling the pipe port to be pulled from multiple directions to open the pipe port. The first hinge frame 51 and the second hinge frame 55 are fixed structures. A rotating arm 52 is mounted on the first hinge frame 51 via a shaft. The rotating arm 52 itself is L-shaped, and the connection point with the shaft is at the angle. Its long end extends to the port of the positioning tube 3 and is connected to the hook rod 53. The hook rod 53 extends inward toward the tube, forming a clamping groove between the hook rod 53 and the long end of the rotating arm 52. The tube wall can be inserted into the clamping groove. At this time, the hook rod 53 and the rotating arm 52 can lock the tube wall. A third hydraulic cylinder 54 is connected to the short end of the rotating arm 52. The third hydraulic cylinder 54 can drive the rotating arm 52 to rotate. When the rotating arm 52 rotates, it can pull the end wall of the tube to achieve the purpose of flaring.

[0032] The specific operating procedure for this device is as follows: (1) First, the pipe that needs to be widened is positioned, that is, the positioning tube 3 is opened, one end of the pipe is placed inside the positioning tube 3, and the area near the end is placed on the support roller 22 of one of the auxiliary pipe axial moving parts 2. Then, the pipe is manually pushed to move along the axis so that the pipe wall at its end is inserted into the groove between the rotating arm 52 and the hook rod 53. (2) To enlarge the pipe, the third hydraulic cylinder 54 drives the rotating arm 52 to rotate. Since the pipe wall is limited by the rotating arm 52 and the hook rod 53, when the rotating arm 52 rotates, the hook rod 53 can fit against the inner wall of the pipe and generate radial pull on the pipe during continuous rotation, thus enlarging the pipe opening. (3) Positioning and assembling the other pipe, that is, placing the end of the other pipe directly on the support roller 22 in another set of auxiliary pipe axial moving parts 2, and then pushing the pipe to move along the axial direction until the port of the pipe is inserted into the port of the other pipe. At this time, the two pipes are assembled. After the complete assembly, the tension of the hook rod 53 on the pipe wall is removed first, and then the mounting base 43 is moved by the first hydraulic cylinder 42 to drive the positioning tube 3 to move, so that the pipe wall slowly gets out of the groove between the rotating arm 52 and the hook rod 53. After the complete separation, the positioning tube 3 can be opened and the connection of the two pipes can be heat-fused. After the fixation is completed, the pipe can be removed from the device.

[0033] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
