Concrete pipe pile docking device

Abstract

This application provides a concrete pipe pile docking device, including two sets of support members arranged along the axial direction of the pipe pile. The two sets of support members support two adjacent pipe pile sections respectively, ensuring the two sections are coaxially aligned. Each set of support members includes a base and a transmission component. The base has two rotating rollers supported on the underside of the pipe pile; the pipe pile rotates synchronously as the rollers rotate. A sliding platform is slidably mounted on the base, abutting against the outer end face of the pipe pile and pushing it to move, thus engaging the two pipe pile sections. The transmission component is mounted on the sliding platform and can move vertically and rotate relative to it; when the transmission component contacts the inner wall of the pipe pile and rotates, the pipe pile rotates synchronously. The concrete pipe pile docking device provided in this application, by selecting either the transmission component or the rotating rollers to drive the pipe pile rotation, or by using both the transmission component and the rotating rollers in combination to drive the pipe pile rotation, can be adapted to products where one of the inner or outer walls of the pipe pile is smooth, ensuring the stability of the concrete pipe pile processing.

Description

Technical Field

[0001] This application belongs to the field of concrete pipe pile processing technology, specifically relating to a concrete pipe pile docking device. Background Technology

[0002] Concrete pipe piles are precast reinforced concrete components mainly used for foundation reinforcement in construction projects, bridges, and other engineering projects. They transfer loads by being driven or pressed into the ground. Because the length of a single pipe pile is limited (usually not exceeding 15 meters), while the actual length required for pipe piles in engineering projects is usually much longer, multiple pipe pile sections need to be joined together to extend the pile during fabrication.

[0003] In existing technologies, pipe piles are usually joined by welding. Specifically, two pipe pile sections are coaxially joined by a joining device, and then the welding equipment is fixed at the joint of the pipe piles and started to connect the two pipe pile sections and form a weld point. Finally, the two pipe pile sections are driven to rotate synchronously, which increases the welding range, forms a weld seam, and connects the two pipe pile sections together.

[0004] The rotation of the concrete pipe pile is achieved by the contact of a rotating roller with its outer or inner wall. Specifically, the rotating roller is in contact with the outer or inner wall of the pipe pile so that the pipe pile rotates synchronously under the influence of friction when the rotating roller rotates.

[0005] The inventors discovered that, depending on product requirements, the inner or outer wall of a concrete pipe pile may be made into a smooth surface (for example, the inner wall of a pipe pile used for drainage may be polished or coated; to reduce the resistance of wave erosion, the outer wall of a pile foundation used in marine engineering may be sprayed with a smooth anti-corrosion material). When the roller comes into contact with the smooth surface, the way tangential force is transmitted through friction is no longer stable. Especially in the later stages of the welding process, the pipe pile may not be able to rotate and welding may not be able to continue, affecting the processing efficiency of the concrete pipe pile. Utility Model Content

[0006] This application provides a concrete pipe pile docking device, which aims to provide different rotation drive methods to adapt to products with smooth inner or outer walls of the pipe pile, so as to avoid the welding process being affected by the inability of the pipe pile to rotate, thereby ensuring the stability of concrete pipe pile processing.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] A concrete pipe pile docking device is provided, comprising two sets of support members arranged along the axial direction of the pipe pile, wherein the two sets of support members are used to support two sections of pipe pile respectively, and the two sections of pipe pile are coaxially arranged; each set of support members includes:

[0009] A base; the base has two rotating rollers supported on the underside of the pipe pile, so that the pipe pile rotates synchronously when the rollers rotate; a sliding platform is slidably disposed on the base, the sliding platform being used to abut against the outer end face of the pipe pile and push the pipe pile to move; and

[0010] A transmission component, disposed on the slide, has a degree of freedom to move up and down relative to the slide, and a degree of freedom to rotate relative to the slide;

[0011] The transmission component is used to insert into the pipe pile and connect with the inner wall of the pipe pile so that the pipe pile rotates synchronously when the transmission component rotates.

[0012] In one possible implementation, the transmission element includes:

[0013] A lifting seat is disposed above the slide table and has an adjustable distance structure between it and the slide table; and

[0014] A rotating ring is rotatably mounted on the lifting seat for inserting the pipe pile, and the axis of the rotating ring is parallel to the axis of the pipe pile; the rotating ring is driven by a first rotating motor.

[0015] The outer circumferential surface of the rotating ring is used to contact the inner wall of the pipe pile so that the pipe pile rotates synchronously when the rotating ring rotates.

[0016] In one possible implementation, the rotating ring further includes:

[0017] At least three telescopic members are arranged at circumferential intervals along the rotating ring, and each is adapted to move radially along the rotating ring so that the rotating ring is coaxially arranged with the pipe pile.

[0018] In one possible implementation, the telescopic element includes:

[0019] A positioning nut is fixedly mounted on the rotating ring, with its axis perpendicular to the axis of the rotating ring; and

[0020] The positioning bolt is threaded onto the positioning nut and has an elastic element at its outer end for abutting against the inner wall of the pipe pile.

[0021] In one possible implementation, the rotating ring has a plurality of through holes spaced apart along its circumference, the plurality of through holes being adapted to allow a plurality of the alignment bolts to pass through in a corresponding manner;

[0022] The inner or outer surface of the rotating ring has multiple recessed grooves that correspond one-to-one with the multiple through holes, and multiple positioning nuts are embedded one-to-one in the multiple recessed grooves.

[0023] In one possible implementation, the adjustment structure includes:

[0024] A receiving groove is formed on the upper side of the slide; and

[0025] A linear cylinder is disposed in the receiving groove, with its power output axis parallel to the vertical direction, and the power output end of the linear cylinder extends out of the receiving groove and is connected to the lifting seat.

[0026] In one possible implementation, the support member further includes:

[0027] A second rotating motor is connected to one of the rotating rollers via a drive.

[0028] In one possible implementation, the support member further includes:

[0029] Two sprockets are located on the outside of the base and are coaxially connected to the two rollers respectively; and

[0030] A drive chain is fitted around the outer circumference of the two sprockets to synchronize their rotation.

[0031] In one possible implementation, a transmission nut is provided on the slide, and a drive screw is threadedly connected to the transmission nut on the base;

[0032] When the drive screw rotates, the transmission nut drives the slide to move.

[0033] In one possible implementation, the base has a guide rod that is slidably connected to the slide, and the guide rod and the drive screw are respectively located on opposite sides of the slide.

[0034] In this embodiment, two sets of support members support two sections of pipe piles respectively, so that the two sections of pipe piles are arranged coaxially. Then, by pushing the slide, the adjacent ends of the two sections of pipe piles can be brought into contact with each other, at which time the operator can weld them.

[0035] During the welding process, different driving modes can be selected according to the arrangement of the smooth and rough surfaces of the pipe pile. Specific driving modes include:

[0036] (i) When the outer wall of the pipe pile is rough and the inner wall is smooth, after the pipe pile is placed on the upper side of two rotating rollers, one of the rotating rollers is driven to rotate, or both rotating rollers are driven to rotate at the same speed and in the same direction, so that the outer surface of the rotating rollers and the outer wall of the pipe pile rub against each other, thereby achieving the technical purpose of rotating the pipe pile.

[0037] (ii) When the inner wall of the pipe pile is rough and the outer wall is smooth, after placing the pipe pile on the upper side of the two rotating rollers, adjust the position of the slide table so that the transmission component is inserted into the pipe pile, and then adjust the position of the transmission component so that the transmission component is in contact with the inner wall of the pipe pile; finally, by driving the transmission component to rotate, the outer surface of the transmission component and the inner wall of the pipe pile are rubbed together to achieve the technical purpose of rotating the pipe pile.

[0038] (iii) When both the inner and outer walls of the pipe pile are smooth, after placing the pipe pile on the upper side of the two rotating rollers, adjust the position of the slide table so that the transmission component is inserted into the pipe pile. Then adjust the position of the transmission component so that the transmission component is in contact with the inner wall of the pipe pile. Finally, drive the rotating rollers and the transmission component to rotate at the same time, and control the rotation speed and keep them rotating in the same direction. This causes friction between the outer surface of the transmission component and the inner wall of the pipe pile, and friction between the outer surface of the rotating rollers and the outer wall of the pipe pile, to ensure the stability of the pipe pile rotation. At the same time, since the transmission component and the inner wall of the pipe pile are in contact, the outer wall of the pipe pile can maintain a tighter contact with the rotating rollers, further ensuring the stability of the pipe pile rotation.

[0039] The concrete pipe pile docking device provided in this embodiment, compared with the prior art, can simultaneously adapt to products with smooth inner walls and rough outer walls, as well as products with rough inner walls and smooth outer walls, improving the versatility of the device and avoiding the welding process being affected by the inability of the pipe pile to rotate, thereby ensuring the stability of concrete pipe pile processing.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0057] Please refer to the following: Figures 1 to 11 The concrete pipe pile docking device provided in this application will now be described. The concrete pipe pile docking device proposed in this application includes two sets of support members.

[0058] In practical use, two sets of support members are arranged along a straight line on the ground or other mounting surface, and the two sections of pipe piles to be welded are placed on the two sets of support members respectively, so that the axial direction of the pipe piles is parallel to the straight line direction, and the two sections of pipe piles are coaxially arranged. In this embodiment, for ease of description, the arrangement direction of the two sets of support members is directly described as the axial direction of the pipe piles.

[0059] Each set of support components includes a base 1 and a transmission component 2.

[0060] The base 1 includes a base plate for placement on the ground or mounting surface, and two side plates fixed to the base plate on both sides facing the axial direction of the pipe pile. The base 1 has two rotating rollers 3, which are arranged side-by-side in a horizontal direction perpendicular to the axial direction of the pipe pile. In actual use, the rotating rollers 3 support the underside of the pipe pile so that when the rollers 3 rotate, they can transmit force to the pipe pile, causing the pipe pile to rotate synchronously.

[0061] A sliding platform 4 is slidably mounted on the base 1. This sliding platform 4 is used to abut the outer end face of the pipe pile. It should be noted that the outer end face of the pipe pile is the end of the pipe pile that faces away from the pipe pile it is welded to. Correspondingly, the end of the two pipe piles welded together is the inner end of the pipe pile. When the sliding platform 4 abuts the outer end of the pipe pile, by driving the sliding platform 4 to move, the pipe pile can be pushed towards the other pipe pile.

[0062] The transmission component 2 is mounted on the slide table 4 and has the freedom to move up and down relative to the slide table 4, as well as the freedom to rotate relative to the slide table 4. When the slide table 4 abuts against the outer end face of the pipe pile, by driving this transmission component 2 to move up and down, the outer surface of the transmission component 2 can abut against the inner wall of the pipe pile, so that when the transmission component 2 rotates, it can provide a force to the pipe pile, causing the pipe pile to rotate synchronously.

[0063] In this embodiment, two sets of support members support two sections of pipe piles respectively, so that the two sections of pipe piles are arranged coaxially. Then, by pushing the slide table 4, the adjacent ends of the two sections of pipe piles can be brought into contact with each other, and the operator can then weld them.

[0064] During the welding process, different driving modes can be selected according to the arrangement of the smooth and rough surfaces of the pipe pile. Specific driving modes include:

[0065] (i) When the outer wall of the pipe pile is rough and the inner wall is smooth, after the pipe pile is placed on the upper side of the two rotating rollers 3, one of the rotating rollers 3 is driven to rotate, or both rotating rollers 3 are driven to rotate at the same speed and in the same direction, so that the outer surface of the rotating roller 3 and the outer wall of the pipe pile rub against each other, thereby achieving the technical purpose of rotating the pipe pile.

[0066] (ii) When the inner wall of the pipe pile is rough and the outer wall is smooth, after placing the pipe pile on the upper side of the two rotating rollers 3, adjust the position of the slide table 4 so that the transmission component 2 is inserted into the pipe pile, and then adjust the position of the transmission component 2 so that the transmission component 2 is in contact with the inner wall of the pipe pile; finally, by driving the transmission component 2 to rotate, the outer surface of the transmission component 2 and the inner wall of the pipe pile are rubbed together to achieve the technical purpose of rotating the pipe pile.

[0067] (iii) When both the inner and outer walls of the pipe pile are smooth, after placing the pipe pile on the upper side of the two rotating rollers 3, adjust the position of the slide table 4 so that the transmission component 2 is inserted into the pipe pile. Then adjust the position of the transmission component 2 so that the transmission component 2 is in contact with the inner wall of the pipe pile. Finally, drive the rotating rollers 3 and the transmission component 2 to rotate at the same time, and control the rotation speed and keep them rotating in the same direction so that the outer surface of the transmission component 2 rubs against the inner wall of the pipe pile and the outer surface of the rotating roller 3 rubs against the outer wall of the pipe pile to ensure the stability of the pipe pile rotation. At the same time, since the transmission component 2 and the inner wall of the pipe pile are in contact, the outer wall of the pipe pile can maintain a tighter contact with the rotating roller 3, further ensuring the stability of the pipe pile rotation.

[0068] The concrete pipe pile docking device provided in this embodiment, compared with the prior art, can simultaneously adapt to products with smooth inner walls and rough outer walls, as well as products with rough inner walls and smooth outer walls, improving the versatility of the device and avoiding the welding process being affected by the inability of the pipe pile to rotate, thereby ensuring the stability of concrete pipe pile processing.

[0069] In some embodiments, such as Figure 4 , Figure 8 and Figure 9 As shown, the transmission component 2 includes a lifting seat 21 and a rotating ring 22.

[0070] The lifting seat 21 is located above the slide table 4. The lifting seat 21 has the freedom to move in the vertical direction relative to the slide table 4, and there is an adjustment structure 5 between it and the slide table 4. This adjustment structure 5 can drive the lifting seat 21 to move relative to the slide table 4, so as to change the distance between the upper surface of the slide table 4 and the lower surface of the lifting seat 21.

[0071] The rotating ring 22 is rotatably mounted on the lifting seat 21. Specifically, the rotating ring 22 is located on the side of the lifting seat 21 that abuts against the pipe pile. Its inner ring surface has connecting rods extending radially inward. There are multiple connecting rods, and these multiple connecting rods are arranged at intervals along the circumference of the rotating ring 22. Based on this, the center of the rotating ring 22 has a central disk that is fixedly connected to each connecting rod, and the central disk is rotatably connected to the lifting seat 21.

[0072] When the sliding table 4 abuts against the outer end face of the pipe pile, the rotating ring 22 can be inserted into the inside of the pipe pile, and the axis of the rotating ring 22 is parallel to the axis of the pipe pile; based on this, by adjusting the position of the lifting seat 21, the outer surface of the rotating ring 22 can abut against the inner wall of the pipe pile.

[0073] The rotating ring 22 is connected to a first rotating motor 221; the first rotating motor 221 is used to drive the rotating ring 22 to rotate and make the pipe pile rotate synchronously.

[0074] In some embodiments, such as Figure 9 and Figure 10 As shown, the rotating ring 22 also includes at least three telescopic members 6, which are spaced apart circumferentially along the rotating ring 22 and are all adapted to move radially along the rotating ring 22 so that the protruding end of the telescopic member 6 abuts against the inner wall of the pipe pile and the rotating ring 22 is coaxially arranged with the pipe pile.

[0075] By adopting the above technical solution, when the rotating ring 22 is coaxially set with the pipe pile, the telescopic member 6 can abut against the inner wall of the pipe pile, which ensures that the rotating ring 22 and the pipe pile maintain a coaxial positional relationship on the one hand, and improves the stability of the synchronous rotation of the rotating ring 22 and the pipe pile on the other hand.

[0076] In some embodiments, such as Figure 9 and Figure 10 As shown, the telescopic component 6 includes a positioning nut 61 and an alignment bolt 62.

[0077] The positioning nut 61 is fixedly mounted on the rotating ring 22, and its axis is perpendicular to the axis of the rotating ring 22.

[0078] The positioning bolt 62 is threaded onto the positioning nut 61, and its outer end has an elastic element 621 for abutting against the inner wall of the pipe pile; specifically, when the elastic element 621 abuts against the inner wall of the pipe pile, the elastic element 621 undergoes elastic contraction to increase its contact area with the inner wall of the pipe pile without damaging the inner wall of the pipe pile.

[0079] In some embodiments, such as Figures 9 to 11 As shown, the rotating ring 22 has a plurality of through holes 222 spaced apart along its circumference, and the plurality of through holes 222 are adapted to allow a plurality of alignment bolts 62 to pass through one by one.

[0080] The inner or outer surface of the rotating ring 22 has multiple recessed grooves 223 that correspond one-to-one with multiple through holes 222. Multiple positioning nuts 61 are embedded in the multiple recessed grooves 223 to achieve the interlocking installation of the positioning nuts 61 and improve the strength and stability of the installation structure.

[0081] In some embodiments, such as Figure 4 and Figure 7 As shown, the adjustable distance structure 5 includes a receiving groove 51 and a linear cylinder 52.

[0082] The receiving groove 51 is located on the upper side of the slide 4.

[0083] The linear cylinder 52 is installed in the receiving groove 51. Its power output axis is parallel to the vertical direction, and the power output end of the linear cylinder 52 extends out of the receiving groove 51 and is connected to the lifting seat 21 to drive the lifting seat 21 to rise and fall relative to the slide table 4.

[0084] Based on this, a cover is also provided at the opening of the receiving groove 51 to close the receiving groove 51 and abut against the upper end of the linear cylinder 52.

[0085] In some embodiments, such as Figure 2 and Figure 5 As shown, the support also includes a second rotating motor 31, which is connected to one of the rotating rollers 3 in a transmission connection. Specifically, the rotating roller 3 extends to the outside of the side plate of the base 1, and the second rotating motor 31 is fixed to the outer side of the side plate of the base 1 and is coaxially connected to the extended end of the rotating roller 3 in a transmission connection to realize the automated driving of a single rotating roller 3.

[0086] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the support also includes two sprockets 32 and a drive chain 321.

[0087] Both sprockets 32 are located on the outside of the base 1 and are coaxially connected to the two rollers 3 respectively; specifically, both rollers 3 pass through the side plate of the base 1 and extend out, and the two sprockets 32 are coaxially connected to the extended ends of the two rollers 3 respectively.

[0088] The transmission chain 321 is fitted around the outer periphery of the two sprockets 32 to synchronize the rotation of the two sprockets 32, thereby realizing the automated drive of the two rollers 3 under the requirements of the same speed and the same direction.

[0089] In some embodiments, such as Figure 4 and Figure 6 As shown, a transmission nut 41 is provided on the slide table 4. Specifically, the outer side of the slide table 4 has a protrusion, and the transmission nut 41 is fixedly connected to this protrusion. The axial direction of the transmission nut 41 is parallel to the sliding direction of the slide table 4.

[0090] The base 1 has a drive screw 11 that is threadedly connected to the transmission nut 41. The drive screw 11 is rotatably connected to the base 1, and one end of the drive screw 1 has a handle that is easy to control manually.

[0091] By adopting the above technical solution, when the drive screw 11 rotates, the transmission nut 41 drives the slide table 4 to move.

[0092] In some embodiments, such as Figure 3 As shown, the base 1 has a guide rod 12, which is fixedly connected to the base 1 and slidably connected to the slide table 4 to realize the sliding connection between the slide table 4 and the base 1 and to limit the sliding direction of the slide table 4.

[0093] The guide rod 12 and the drive screw 11 are located on opposite sides of the slide table 4 to ensure the stability of the slide table 4 during movement.

[0094] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
