Description

Technical Field

[0001] This utility model relates to the field of pipeline construction positioning technology, specifically a positioning device for rainwater and sewage pipeline construction. Background Technology

[0002] The sewage pipeline system consists of pipes and ancillary structures for collecting and transporting urban sewage. Sewage flows from branch pipes into main pipes, then into the main trunk, and finally into the sewage treatment plant. The pipes are distributed in a tree-like pattern, with the size of the pipes increasing from small to large. During construction, equipment is needed to assist in positioning the pipes.

[0003] According to a public notice (Announcement No.: CN217232143U), the aforementioned application describes a municipal stormwater and sewage pipeline construction positioning device. The device utilizes an electric telescopic rod, a C-shaped fixing frame, and a pipe support. The C-shaped fixing frame, in conjunction with the electric telescopic rod and pipe support, allows the sewage pipeline construction positioning device to raise and lower sewage pipelines of different diameters within a certain range. Additionally, the sewage pipeline can be rotated, making the installation of the sewage pipeline more convenient.

[0004] However, existing stormwater and sewage pipes are usually laid underground, and these pipes themselves have a large mass. During installation, calibration, positioning, and fixing are required. Existing positioning devices are complex to align when assisting in pipe installation, requiring manual control and transportation, resulting in low accuracy and being time-consuming and labor-intensive. Therefore, we propose a positioning device for stormwater and sewage pipe construction. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for the construction of rainwater and sewage pipelines, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for rainwater and sewage pipeline construction, comprising a frame, a telescopic support rod fixedly installed at the bottom of the frame, casters fixedly installed at the bottom end of the telescopic support rod, a crossbar fixedly installed on the inner wall of the frame, a threaded plate slidably installed on the inner surface of the crossbar, a conveyor frame fixedly installed on the lower surface of the threaded plate, a servo motor fixedly installed on the inner wall of the crossbar, a threaded rod fixedly installed at the output end of the servo motor, and a calibration module provided at the bottom of the frame;

[0007] The calibration module includes a first calibration frame, which is fixedly installed on the inner wall of one end of the frame. A connecting plate is fixedly connected to the side wall of the first calibration frame. A second calibration frame is fixedly installed on the side of the connecting plate away from the first calibration frame. A sliding sleeve is slidably installed on the inner wall of the second calibration frame. A rotating block is rotatably installed on the inner wall of the sliding sleeve. A protruding strip is fixedly installed on the arc-shaped outer wall of the sliding sleeve. A contact wheel is rotatably installed on the inner wall of the rotating block. A top rod is fixedly installed on the side of the rotating block away from the contact wheel. A telescopic rod is rotatably connected to the end of the top rod. A small spring is sleeved on the outer wall of the telescopic rod.

[0008] Preferably, a stop block is slidably installed on the inner wall of the first calibration frame, a return spring is fixedly connected between the stop block and the inner wall of the first calibration frame, a diagonal rod is hinged to the side wall of the stop block, a connecting rod is hinged to the end of the diagonal rod, a push plate is fixedly installed at the end of the connecting rod, a fork rod is fixedly installed on the side wall of the push plate, and a beveled ring is fixedly installed on the outer wall of the push rod.

[0009] Preferably, the inner wall of the second calibration frame is provided with a circular hole whose inner diameter matches the outer diameter of the sliding sleeve, and the arc-shaped inner surface of the circular hole is provided with a sliding groove that matches the size of the protrusion. The protrusion and the sliding groove slide together, restricting the sliding sleeve to slide within the circular hole without rotating.

[0010] Preferably, the arc-shaped outer surface of the contact wheel is provided with an arc-shaped inner groove, so that the contact surface is V-shaped when the contact wheel comes into contact with the outer surface of the rainwater and sewage pipe, thereby preventing the contact wheel from shifting with the rainwater and sewage pipe and ensuring that only rolling occurs between the two.

[0011] Preferably, the number of abutments is set in two sets, and the two sets of abutments are mirror images of each other on the inner walls of the front and rear sides of the first calibration frame. The side of the abutment closest to the second calibration frame is set in an arc shape to avoid motion interference between the abutment and the end of the rainwater and sewage pipe.

[0012] Preferably, the second calibration frame is provided with a torsion module, the torsion module includes a fixing sleeve, the fixing sleeve is fixedly installed on the inner wall of the circular hole, the inner wall of the fixing sleeve is provided with an arc groove, and the arc-shaped outer wall of the top rod is fixedly installed with a convex ball, the convex ball and the arc groove are slidably engaged.

[0013] Preferably, the arc-shaped groove is spirally arranged, and the included angle between the two ends of the arc-shaped groove is set to 90°. When the contact wheel retracts slightly into the circular hole along with the push rod, it is guided by the arc-shaped groove and will eventually rotate 90°.

[0014] Compared with the prior art, this utility model provides a positioning device for the construction of rainwater and sewage pipelines, which has the following beneficial effects:

[0015] 1. This positioning device for rainwater and sewage pipeline construction, equipped with a calibration module, pushes the frame towards the already installed rainwater and sewage pipeline. The second calibration frame first moves to the outside of the rainwater and sewage pipeline. Due to the constraint of the connecting plate, the second calibration frame also moves to the outer surface of the rainwater and sewage pipeline. At this time, the horizontal limiting of the first and second calibration frames ensures that the rainwater and sewage pipeline to be installed on the frame can be aligned with the already installed rainwater and sewage pipeline. Furthermore, no recalibration is required during the docking installation process. The first and second calibration frames also prevent the frame from shifting, ensuring the accuracy and efficiency of the rainwater and sewage pipeline docking process.

[0016] 2. The positioning device used for the construction of rainwater and sewage pipelines, during the frame docking process, involves the first calibration frame contacting the surface of the installed rainwater and sewage pipeline to press against the abutment block. In conjunction with the inclined rod and connecting rod, the push plate pushes the fork rod, which presses against the inclined ring and the top rod, causing the contact wheel to slightly retract into the circular hole. This prevents the contact wheel and the second calibration frame from slipping on the surface of the rainwater and sewage pipeline, which would affect the docking and installation accuracy of the frame and the rainwater and sewage pipeline to be installed.

[0017] 3. The positioning device for rainwater and sewage pipeline construction is equipped with a torsion module. When the contact wheel retracts slightly into the circular hole along with the top rod, it is guided by the arc groove and the contact wheel will eventually rotate 90° to form a transverse anti-slip structure on the outer wall of the end of the installed rainwater and sewage pipeline. This ensures the relative stability of the frame at the end of the rainwater and sewage pipeline, thereby ensuring the accuracy and safety of the subsequent docking process.

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a positioning device for the construction of rainwater and sewage pipelines, including a frame 1, a telescopic support rod 2 fixedly installed at the bottom of the frame 1, a caster 3 fixedly installed at the bottom end of the telescopic support rod 2, a crossbeam 4 fixedly installed on the inner wall of the frame 1, a threaded plate 5 slidably installed on the inner surface of the crossbeam 4, a conveyor frame 6 fixedly installed on the lower surface of the threaded plate 5, a servo motor 7 fixedly installed on the inner wall of the crossbeam 4, a threaded rod 8 fixedly installed at the output end of the servo motor 7, and a calibration module 9 provided at the bottom of the frame 1. The calibration module 9 includes a first calibration frame 91, a connecting plate 93, a second calibration frame 92, a sliding sleeve 94, a rotating block 96, a protruding strip 95, a contact wheel 97, a top rod 98, a telescopic rod 99, a small spring 910, a stop block 911, a return spring 912, a diagonal rod 913, a connecting rod 914, a push plate 915, a fork rod 916, and a inclined ring 917.

[0026] In one embodiment of this utility model, a first calibration frame 91 is fixedly installed on the inner wall of one end of the frame 1. A connecting plate 93 is fixedly connected to the side wall of the first calibration frame 91. A second calibration frame 92 is fixedly installed on the side of the connecting plate 93 away from the first calibration frame 91. A sliding sleeve 94 is slidably installed on the inner wall of the second calibration frame 92. A rotating block 96 is rotatably installed on the inner wall of the sliding sleeve 94. A protruding strip 95 is fixedly installed on the arc-shaped outer wall of the sliding sleeve 94. A contact wheel 97 is rotatably installed on the inner wall of the rotating block 96. A top is fixedly installed on the side of the rotating block 96 away from the contact wheel 97. The end of the rod 98 is rotatably connected to a telescopic rod 99. A small spring 910 is sleeved on the outer wall of the telescopic rod 99. A stop block 911 is slidably installed on the inner wall of the first calibration frame 91. A return spring 912 is fixedly connected between the stop block 911 and the inner wall of the first calibration frame 91. A diagonal rod 913 is hinged to the side wall of the stop block 911. A connecting rod 914 is hinged to the end of the diagonal rod 913. A push plate 915 is fixedly installed at the end of the connecting rod 914. A fork rod 916 is fixedly installed on the side wall of the push plate 915. A inclined ring 917 is fixedly installed on the outer wall of the rod 98.

[0027] Furthermore, the casters 3 have a self-locking structure, which can maintain the current position after the frame 1 transports the rainwater and sewage pipes to the target position, so as to facilitate the docking and installation of the rainwater and sewage pipes. At the same time, there are two sets of threaded plates 5 and conveyor frames 6, and there is a gap between the two sets of threaded plates 5 and conveyor frames 6, so that the rainwater and sewage pipes to be docked and installed can be placed on the two sets of conveyor frames 6. Specifically, after the calibration module 9 of the frame 1 is docked and calibrated with the already installed pipes, the servo motor 7 is started. Through the rotation of the threaded rod 8, the two sets of threaded plates 5 drive the two sets of conveyor frames 6 to slide horizontally along the inner surface of the crossbeam 4, so as to push the rainwater and sewage pipes to be installed toward the end of the already installed pipes until the two are docked. The workers use installation tools to complete the splicing and installation of the rainwater and sewage pipes.

[0028] Specifically, the first calibration frame 91 and the second calibration frame 92 are exactly the same size as the conveyor frame 6 to better adapt to the conveying operation of the rainwater and sewage pipes. Meanwhile, the inner wall of the second calibration frame 92 has a circular hole with an inner diameter matching the outer diameter of the sliding sleeve 94, and the arc-shaped inner surface of the circular hole has a groove matching the size of the protrusion 95. The protrusion 95 slides in the groove, restricting the sliding sleeve 94 to slide within the circular hole without rotation. Furthermore, the arc-shaped outer surface of the contact wheel 97 has an arc-shaped inner groove, so that the contact surface of the contact wheel 97 is V-shaped when it contacts the outer surface of the rainwater and sewage pipe, thereby preventing misalignment between the contact wheel 97 and the rainwater and sewage pipe and ensuring that only rolling occurs between them. Further, the end of the push rod 98 has a circular groove, and the end of the telescopic rod 99 is rotatably installed in this circular groove. Furthermore, the end of the small spring 910 is also located in the circular groove, so that the push rod 98 has a tendency to slide away from the inner wall of the second calibration frame 92 due to the elastic force of the small spring 910 during actual use. During the process of pushing the frame 1 towards the side of the already installed rainwater and sewage pipe, the second calibration frame 92 first moves to the outside of the rainwater and sewage pipe. By the restriction of the connecting plate 93, the second calibration frame 92 will also move to the outer surface of the rainwater and sewage pipe. At this time, by the horizontal limiting of the first calibration frame 91 and the second calibration frame 92, the rainwater and sewage pipe to be installed on the frame 1 can be aligned with the already installed rainwater and sewage pipe, and no recalibration is required during the docking installation process. The first calibration frame 91 and the second calibration frame 92 can also prevent the frame 1 from shifting, ensuring the accuracy and efficiency of the rainwater and sewage pipe docking process.

[0029] In addition, two sets of abutment blocks 911 are provided, with the two sets of abutment blocks 911 mirror-mounted on the inner walls of the front and rear sides of the first calibration frame 91. The end of the return spring 912 is fixedly connected to the inner wall of the first calibration frame 91. The side of the abutment block 911 closest to the second calibration frame 92 is provided with an arc-shaped surface to avoid motion interference between the abutment block 911 and the end of the rainwater and sewage pipe. Furthermore, the push plate 915 is slidably installed on the inner wall of the second calibration frame 92. The connecting rod 914 passes through and is slidably connected to the connecting plate 93. The abutment block 911 is pressed against the surface of the rainwater and sewage pipe. Sliding towards the inside of the first calibration frame 91, the connecting rod 914 pushes the push plate 915 towards the center of the second calibration frame 92 through the push of the inclined rod 913. This causes the fork rod 916 to press the inclined ring 917, which in turn causes the inclined ring 917 to drive the top rod 98 to press the telescopic rod 99 and the small spring 910. This results in a slight contraction of the contact wheel 97 towards the inside of the second calibration frame 92, preventing the contact wheel 97 and the second calibration frame 92 from slipping on the surface of the rainwater and sewage pipes, which would affect the installation accuracy of the frame 1 and the rainwater and sewage pipes to be installed.

[0030] In an embodiment of this utility model, a torsion module 10 is provided inside the second calibration frame 92. The torsion module 10 includes a fixing sleeve 101. The fixing sleeve 101 is fixedly installed on the inner wall of the circular hole. An arc groove 102 is opened on the inner wall of the fixing sleeve 101. A convex ball 103 is fixedly installed on the arc-shaped outer wall of the top rod 98. The convex ball 103 slides in cooperation with the arc groove 102.

[0031] It is worth noting that the outer diameter of the push rod 98 is adapted to the inner cavity diameter of the fixed sleeve 101, so that the push rod 98 can move inside the fixed sleeve 101. The arc groove 102 is spirally arranged, and the plane angle between the two ends of the arc groove 102 is set to 90°. When the contact wheel 97 slightly retracts into the circular hole with the push rod 98, guided by the arc groove 102, the contact wheel 97 will eventually rotate 90° to form a transverse anti-slip structure on the outer wall of the end of the installed rainwater and sewage pipe, ensuring the relative stability of the frame 1 at the end of the rainwater and sewage pipe, thereby ensuring the accuracy and safety of the subsequent docking process.

[0032] In this invention, during use, the stormwater and sewage pipe to be installed is placed on two sets of conveyor frames 6. Then, the frame 1 is pushed towards the end of the already installed stormwater and sewage pipe. First, the second calibration frame 92 is aligned with the end of the already installed stormwater and sewage pipe. Then, the frame 1 is pushed further, so that the second calibration frame 92 and the first calibration frame 91 are sequentially fitted onto the outside of the end of the already installed stormwater and sewage pipe. This ensures that the stormwater and sewage pipe to be installed on the frame 1 is aligned with the already installed stormwater and sewage pipe, and no further calibration is required during the installation process. The first calibration frame 91 and the second calibration frame 92 can also... To prevent the frame 1 from shifting and ensure the accuracy and efficiency of the rainwater and sewage pipe docking process, as the first calibration frame 91 contacts the surface of the installed rainwater and sewage pipe, it presses against the abutment block 911. In conjunction with the inclined rod 913 and the connecting rod 914, the push plate 915 pushes the fork rod 916. The fork rod 916 presses against the inclined ring 917 and the top rod 98, causing the contact wheel 97 to slightly retract into the circular hole. This prevents the contact wheel 97 and the second calibration frame 92 from slipping on the surface of the rainwater and sewage pipe, which would affect the docking and installation accuracy of the frame 1 and the rainwater and sewage pipe to be installed.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
