Auxiliary installation device and installation method for large-diameter socket pipes

Abstract

This invention discloses an auxiliary installation device and method for large-diameter socket pipes, relating to the field of socket pipe installation technology. The invention includes a moving platform, a clamping mechanism, and a traction mechanism. Two conversion frames are mounted on the moving platform, with a first guide shaft and a second guide shaft positioned between them. Two traction ropes connect the clamping mechanism and the traction mechanism. Locking components are provided at both ends of each conversion frame. The cooperation of the first and second guide shafts and the conversion frames changes the position of the traction rope's point of force, thereby changing the direction of the traction rope's tension. This reduces friction and corrects deviation, ensuring strict alignment of the socket pipe when one end is raised. When the first and second guide shafts are at the bottom of the conversion frames, it facilitates the insertion of the socket pipe. During installation, only one person needs to control the traction mechanism, and another person needs to move the first and second guide shafts and perform final correction, greatly reducing manual labor and simplifying operation.

Description

Technical Field

[0001] This invention relates to the field of socket pipe installation technology, specifically to an auxiliary installation device and installation method for large-diameter socket pipes. Background Technology

[0002] With the rapid development of my country's economy, the country has gradually accelerated the construction of urban infrastructure, the most important of which is the construction of new municipal roads and the renovation of drainage projects in old urban areas. According to the 2016 Urban and Rural Construction Statistical Bulletin, at the end of 2016, the length of urban roads in my country reached 382,000 kilometers, an increase of 4.8% over the previous year, and the corresponding urban pipe network also increased significantly. The drainage system is the heart of a city and an important supporting facility for urban municipal roads. Drainage pipe interfaces are a crucial component of underground stormwater and sewage drainage projects; their construction quality directly affects the quality of the entire project and the normal operation of the entire drainage system.

[0003] Currently, socket-type HDPE sewage pipes and socket-type reinforced concrete rainwater pipes are widely used in drainage engineering. Compared with plain-end concrete pipes, they have stronger adaptability and better anti-leakage performance. In general pipeline construction, the pipe socket joints are installed by mechanical hoisting combined with manual installation. In actual construction, the following problems exist: 1) Low construction accuracy and uncontrollable quality; 2) Low installation efficiency and high labor costs; in particular, the installation and removal of hinges require a lot of time and effort for unskilled workers; during retraction, manual judgment of pipe offset and insertion depth is required, which is inefficient. According to on-site observations, it takes approximately 45-60 minutes for four workers to simultaneously install a 10m long DN500 sewage pipe.

[0004] Currently, rainwater reinforced concrete pipes are generally installed manually using jacks or excavators. This requires high levels of expertise from the site and specialized operators, and the jacking and correction are difficult. In addition, the construction of spigot and socket pipes mostly requires mechanical hoisting combined with manual labor. The low efficiency of manual spigot joints also keeps the machinery in standby mode, increasing labor and machinery operating costs and significantly increasing construction costs. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary installation device and installation method for large-diameter socket pipes to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary installation device for large-diameter socket pipes, including a movable platform, a clamping mechanism for holding the socket pipe, and a traction mechanism for pulling the clamping mechanism. Two conversion frames are fixedly installed on the movable platform, and a first guide shaft and a second guide shaft for changing the force direction of the clamping mechanism are slidably arranged between the two conversion frames. Two traction ropes are connected between the clamping mechanism and the traction mechanism, and both traction ropes pass through the first guide shaft and the second guide shaft. Locking components for fixing the positions of the first guide shaft and the second guide shaft are provided at both ends of each conversion frame.

[0007] Preferably, the clamping mechanism includes a first clamping clamp and a second clamping clamp, with two bolts disposed between the first clamping clamp and the second clamping clamp.

[0008] Preferably, each of the traction ropes has a pull ring fixedly installed at the end away from the traction mechanism.

[0009] Preferably, the traction mechanism includes two winding frames fixedly mounted on a moving platform, a synchronizing rod is provided between the two winding frames, a servo motor is fixedly mounted on the moving platform, and the output end of the servo motor is fixedly connected to one of the winding frames.

[0010] Preferably, two first support rods and two second support rods are fixedly provided on both sides of the mobile platform, and the ends of each first support rod and second support rod away from the mobile platform are fixedly connected to the two sides of each conversion frame respectively; a downward pressure rod is rotatably provided between the two first support rods.

[0011] Preferably, the locking assembly includes a first fixing plate and a second fixing plate fixedly disposed at both ends of each conversion frame, each second fixing plate is provided with a movable plate, and each movable plate is fixedly disposed with three insert rods.

[0012] Preferably, both sides of the mobile platform are provided with lifting plates, and each lifting plate has a bearing plate rotatably mounted on the end away from the servo motor.

[0013] Preferably, top rods are fixedly provided on both sides of the second clamping hoop, and limit plates are fixedly provided on each of the lifting plates.

[0014] Preferably, the movable platform has a through groove for the first guide spool and the second guide spool to pass through, and a rope groove for the two traction ropes to pass through.

[0015] A method for installing large-diameter socket pipes, based on the aforementioned installation device, includes the following steps: moving a moving platform to the installation position and aligning the centerline of the moving platform with the installation centerline; moving the first and second guide shafts to the top of the conversion frame and fixing their positions using locking components; placing the socket pipe in a suitable position using a crane, clamping the socket pipe with the first and second clamping clamps, and ensuring the bolts pass through the corresponding pull rings during installation; starting a servo motor to drive a traction rope and move the socket pipe closer to the moving platform; when the second clamping clamp raises the end of the insertion rod near the moving platform, moving the first and second guide shafts to the bottom of the conversion frame; starting the servo motor again to firmly insert the uninstalled socket pipe into the socket of the installed socket pipe, completing the installation.

[0016] In the above technical solution, the present invention provides an auxiliary installation device and method for large-diameter socket pipes, which has the following beneficial effects: the socket pipe is clamped by a clamping mechanism, and the clamping mechanism is moved by a traction mechanism and a traction rope, thereby moving the socket pipe. The position of the traction rope's force point can be changed by the cooperation of the first and second guide shafts and the conversion frame, thereby changing the direction of the traction rope's tension. When the first and second guide shafts are above the conversion frame, they can reduce friction and correct deviation. When the second guide shaft and the traction rope lift one end of the socket pipe, the worker can easily rotate the end of the socket pipe, thereby ensuring that the socket pipe is strictly aligned. When the first and second guide shafts are at the bottom of the conversion frame, it is convenient to push the socket pipe in. During the installation process, only one person needs to control the traction mechanism, and one person needs to move the first and second guide shafts and perform the final correction, thereby greatly reducing manual labor and making it convenient to use.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-7 A large-diameter socket pipe auxiliary installation device includes a movable platform 7, a clamping mechanism for holding the socket pipe, and a traction mechanism for pulling the clamping mechanism. Two conversion frames 21 are fixedly installed on the movable platform 7. A first wire guide shaft 23 and a second wire guide shaft 24 for changing the force direction of the clamping mechanism are slidably installed between the two conversion frames 21. Two traction ropes 15 are connected between the clamping mechanism and the traction mechanism. Both traction ropes 15 pass through the first wire guide shaft 23 and the second wire guide shaft 24. Locking components for fixing the position of the first wire guide shaft 23 and the second wire guide shaft 24 are provided at both ends of each conversion frame 21.

[0029] Specifically, the two conversion frames 21 are inclined at an angle, the distance between the tops of the two conversion frames 21 is much smaller than the distance between the bottoms, and the distance between the bottoms of the two conversion frames 21 is slightly larger than the diameter of the socket tube 2. Four support columns 3 are fixedly installed below the moving platform 7, and each support column 3 is equipped with a roller 4 at its bottom, which facilitates the movement of the moving platform 7. The two traction ropes 15 are of the same length. The first wire guide shaft 23 is set on the upper side of the second wire guide shaft 24. Both ends of the first wire guide shaft 23 are rotatably equipped with connecting plates 22, and both ends of the second wire guide shaft 24 are correspondingly connected to the connecting plates 22. 2. Rotary connection: The first guide shaft 23 and the second guide shaft 24 are connected by a fixed plate. The end of each traction rope 15 furthest from the traction mechanism passes between the first guide shaft 23 and the second guide shaft 24 and connects to the clamping mechanism. When the first guide shaft 23 and the second guide shaft 24 are at the top of the conversion frame 21, the two conversion frames 21 restrict the traction ropes 15 to be close to the second guide shaft 24. When the traction rope 15 is pulled, it applies a force biased towards the centerline to the clamping mechanism, thus facilitating the alignment of the socket tube. Figure 1 As shown, in use, the clamping mechanism is fixed at an appropriate position on the insertion tube 1 of the socket tube. Two traction ropes 15 are fixed to both ends of the clamping mechanism. The first wire guide spool 23 and the second wire guide spool 24 are moved above the two conversion frames 21, and their positions are fixed by the locking assembly above the two conversion frames 21. The traction mechanism is then driven, pulling the traction ropes 15 that pass through the first wire guide spool 23 and the second wire guide spool 24. This causes the traction ropes 15 to apply an upward force along the traction ropes 15 to the clamping mechanism. This force can be decomposed into an upward force and a rightward force. The rightward force can move the socket tube. When the socket tube moves, the upward force reduces the friction between the insertion tube 1 and the ground, thus allowing the position of the insertion tube 1 on the socket tube to be adjusted when the two ropes are taut. The insertion tube moves along the centerline. When the clamping mechanism moves below the second thread guide 24, the traction rope 15 is pulled, causing the end of the insertion tube 1 near the moving platform 7 to lift. When the height of the end of the insertion tube 1 is consistent with the height of the already installed socket tube 2, the height of the insertion tube 1 is fixed. The first thread guide 23 and the second thread guide 24 are moved to the bottom of each conversion frame 21, and the positions of the first thread guide 23 and the second thread guide 24 are fixed by the locking components at the bottom of each conversion frame 21. At this time, the point of force of the traction rope 15 moves to the bottom of the conversion frame 21, and the traction mechanism is started again. At this time, the traction rope 15 provides a greater horizontal rightward pulling force to the clamping mechanism, which facilitates the insertion of the insertion tube 1 into the already installed socket tube 2. After installation, the clamping mechanism is removed from the insertion tube 1, and the traction rope 15 is released, so that the next socket tube can be installed.

[0030] In another embodiment of the present invention: the clamping mechanism includes a first clamping clamp 10 and a second clamping clamp 11, with two bolts 12 disposed between the first clamping clamp 10 and the second clamping clamp 11; the two bolts 12 are symmetrically disposed at both ends of the first clamping clamp 10, and the insertion tube 1 can be tightly clamped between the first clamping clamp 10 and the second clamping clamp 11 by the engagement of the bolts 12 and nuts (not shown in the figure). In use, the second clamping clamp 11 and the first clamping clamp 10 are placed on the upper and lower sides of the insertion tube, respectively. The first clamping clamp 10 and the second clamping clamp 11 are fastened by the bolts 12, thereby enabling the traction rope 15 to pull the insertion tube to move.

[0031] In another embodiment of the present invention: each traction rope 15 is fixedly provided with a pull ring 14 at the end away from the traction mechanism; when installing the first clamping hoop 10 and the second clamping hoop 11, the two pull rings 14 are placed on both sides of the second clamping hoop 11 in a one-to-one correspondence. At this time, each bolt 12 is passed through the pull ring 14 in a one-to-one correspondence and the bolt 12 is tightened. At this time, each traction rope 15 is connected to the bolt 12 through the pull ring 14, so that the traction rope 15 can drive the socket tube to move.

[0032] In another embodiment of the present invention: the traction mechanism includes two winding frames 9 fixedly mounted on a moving platform 7, a synchronizing rod 91 between the two winding frames 9, a servo motor 8 fixedly mounted on the moving platform 7, and the output end of the servo motor 8 fixedly connected to one of the winding frames 9; each winding frame 9 has a rotating shaft 92 rotatably mounted inside it, and the end of each traction rope 15 away from the pull ring 14 is evenly wound on the rotating shaft 92. The two ends of the synchronizing rod 91 pass through the winding frames 9 and are fixedly connected to the rotating shaft 92, and the output tube of the servo motor 8 is fixedly connected to the rotating shaft 92 of one of the winding frames 9. The movement of the traction rope 15 is controlled by the servo motor 8 driving the two rotating shafts 92 to rotate.

[0033] In another embodiment of the present invention: two first support rods 41 and two second support rods 43 are fixedly arranged on both sides of the moving platform 7. The ends of each first support rod 41 and second support rod 43 away from the moving platform 7 are fixedly connected to the two sides of each conversion frame 21 respectively. A pressing rod 42 is rotatably arranged between the two first support rods 41. The two first support rods 41 are located below the moving platform 7, and the two second support rods 43 are located above the moving platform 7. The two conversion frames 21 are supported by the first support rods 41 and the second support rods 43. The ends of each traction rope 15 away from the rotating shaft 92 are all wrapped around the side of the pressing rod 42 away from the moving platform 7 and pass between the first wire guide 23 and the second wire guide 24. The pressing rod 42 restricts the position of the traction rope 15 below the moving platform 7, thereby facilitating the change of the force point of the traction rope 15.

[0034] In another embodiment of the present invention: the locking assembly includes a first fixing plate 25 and a second fixing plate 26 fixedly disposed at both ends of each conversion frame 21. Each second fixing plate 26 is provided with a movable plate 27, and each movable plate 27 is fixedly disposed with three insert rods 28. Each first fixing plate 25 is provided with a insertion hole that cooperates with the insert rods 28. When the first wire guide spool 23 and the second wire guide spool 24 move to the end of the conversion frame 21, the three insert rods 28 are inserted into the corresponding slots. The first wire guide spool 23 and the second wire guide spool 24 are limited by the three insert rods 28 on each movable plate 27, thereby fixing the position of the first wire guide spool 23 and the second wire guide spool 24.

[0035] In another embodiment of the present invention: Elevating plates 31 are provided on both sides of the moving platform 7, and a bearing plate 32 is rotatably mounted on the end of each elevating plate 31 away from the servo motor 8; the elevating plates 31 and their ends are respectively fixedly connected to the corresponding support columns 3; the bottom wall of the conversion frame 21 is slightly higher than the installed insertion tube 1; each elevating plate 31 has a groove for the bearing plate 32 to rotate; when the first wire guide spool 23 and the second wire guide spool 24 are at the top of the conversion frame 21, each bearing plate 32 is at the second wire guide spool 24; when the traction rope 15 pulls the first clamping hoop 10 and the second clamping hoop 11 to the bearing plate 32 through the second wire guide spool 24 at the top of the conversion frame 21, the traction rope 15 is further tightened, causing the first clamping hoop 10 and the second clamping hoop 11 to move upwards, thereby causing the end of the insertion tube 1 closest to the moving platform 7 to also move upwards, and the insertion tube is supported by the bearing plate 32. When the end of the insertion tube 1 near the moving platform 7 is suspended, the end of the insertion tube near the moving platform 7 can be easily rotated to ensure that the insertion tube is aligned with the centerline. When the first clamping hoop 10 and the second clamping hoop 11 move upward, they drive the bearing plates 32 to rotate. When the second clamping hoop 11 falls on the bearing plate 32, the insertion tube 1 between the first clamping hoop 10 and the second clamping hoop 11 is aligned with the end of the installed insertion tube 2. At this time, the servo motor 8 releases the traction rope 15 and then stops the servo motor 8. Then, the first wire guide spool 23 and the second wire guide spool 24 are moved to the bottom of the conversion frame 21. At this time, the force point of the traction rope 15 is switched to the bottom of the conversion frame 21. The servo motor 8 is started. The servo motor 8, through the traction rope 15, tightly inserts the insertion tube 1 of the installed insertion tube into the end of the installed insertion tube 2, thereby completing the installation of one insertion tube.

[0036] In another embodiment of the present invention: top rods 13 are fixedly provided on both sides of the second clamping hoop 11, and limit plates 33 are fixedly provided on each lifting plate 31; the limit plates 33 support the bearing plate 32 to rotate upward. When the second clamping hoop 11 moves upward, each bearing plate 32 is rotated by each top rod 13. When each top rod 13 is above the corresponding bearing plate 32, each top rod 13 is lowered by the servo motor 8. At this time, each top rod 13 falls on the corresponding bearing plate 32, thereby fixing the height of the socket tube 1. At this time, the socket tube 1 is aligned with the installed socket tube 2.

[0037] In another embodiment of the present invention: the moving platform 7 is provided with a through groove 6 for the first guide spool 23 and the second guide spool 24 to pass through, and the moving platform 7 is provided with a rope groove 5 for the two traction ropes 15 to pass through; the through groove 6 facilitates the movement of the first guide spool 23 and the second guide spool 24, and when the first guide spool 23 and the second guide spool 24 are moved downward, the two traction ropes 15 can pass through the rope groove 5.

[0038] A method for installing large-diameter socket pipes, based on the aforementioned installation device, includes the following steps: S1. Moving the moving platform 7 to the installation position and aligning the centerline of the moving platform 7 with the installation centerline, moving the first guide shaft 23 and the second guide shaft 24 to the top of the conversion frame 21, and fixing the positions of the first guide shaft 23 and the second guide shaft 24 by the locking assembly; S2. Placing the socket pipe in an appropriate position using a crane, clamping the socket pipe 1 with the first clamping clamp 10 and the second clamping clamp 11, and ensuring that the bolt 12 passes through the corresponding pull ring 14 when installing the bolt 12; S3. Starting the servo motor 8, which drives the traction rope 15 to move the socket pipe closer to the moving platform 7, and when the second clamping clamp 11 lifts the end of the insertion rod 28 near the moving platform 7, moving the first guide shaft 23 and the second guide shaft 24 to the bottom of the conversion frame 21; S4. Starting the servo motor 8 again, tightly inserting the uninstalled socket pipe 1 into the end of the installed socket pipe 2, completing the installation.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
