Description

Technical Field

[0001] The utility model relates to the field of trenchless pipeline repair, in particular to a traction and steering device for trenchless pipeline repair. Background Art

[0002] In trenchless light-curing pipeline repair construction, it is often necessary to use a traction rope to realize the movement and drive of structures such as a lamp stand or a repair hose in the pipeline. However, the pipeline is generally arranged horizontally, and the traction rope needs to extend vertically downward from the ground to the end of the underground pipeline before entering the pipeline to be repaired. Therefore, a traction steering device needs to be provided at the end of the pipeline to ensure the smooth movement of the traction rope. However, the end of the pipeline needs to be cut with an inner lining hose or tied with a hoop, and the existence of the traction steering device will hinder the above operations and affect the convenience of construction. The existing practice is to remove the traction steering device when performing the above operations, and then install the traction steering device when traction is required after the operation is completed. This method requires frequent disassembly and assembly of the traction steering device, which increases the workload of the overall construction, makes the use of the traction steering device very inconvenient, reduces the overall construction efficiency, and prolongs the construction period of the pipeline repair. Utility Model Content

[0003] The utility model aims to provide a traction steering device for trenchless pipeline repair, which can solve the technical problem that the existence of the existing traction steering device will affect the construction operation of the pipeline end, reduce the frequency of disassembly and assembly operations of the traction steering device, improve its convenience of use, and ensure the efficiency and construction period of the construction.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A traction and steering device for trenchless pipeline repair comprises a support rod and fixed tubes arranged on both sides of the support rod, a fixed plate is provided at one end of the fixed tube, a fixed hole is provided on the fixed plate, the length of the support rod is less than the distance between the two ends of the fixed tube, a steering wheel is rotatably connected to the support rod, sliding columns are symmetrically rotatably connected at both ends of the support rod, the sliding columns are slidably connected in the fixed tube, and a positioning rod used in conjunction with the sliding column is provided on the fixed tube.

[0006] Furthermore, the fixing tube and the sliding column are both provided with notches, and the positioning rod passes through the notch on the fixing tube and then enters into the notch on the sliding column.

[0007] Furthermore, a bracket is provided on the top of the fixing tube, and the top of the positioning rod is rotatably connected to the bracket.

[0008] Furthermore, the top of the positioning rod is located above the middle of the notch.

[0009] Furthermore, guide strips are symmetrically arranged on the inner wall of the fixed tube, guide grooves are symmetrically arranged on the side wall of the sliding column, and the guide strips are slidably connected in the guide grooves.

[0010] Furthermore, the steering wheel is made of ceramic or metal.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The structure of the utility model utilizes the fixing hole on the fixing plate to fix the fixing pipe near the position of the end of the pipeline to be repaired. When in use, the support rod with the steering wheel utilizes the sliding connection between the sliding columns at both ends and the fixing pipe to achieve support, thereby ensuring the stability of the steering wheel in pulling and steering the traction rope. When the construction operation is carried out at the end of the pipeline to be repaired laterally, it is only necessary to slide the support rod to one side so that the sliding column at one end slides out of the fixing pipe, and then slide the support rod in the opposite direction so that the rotation connection position between the sliding column at the other end and the support rod is exposed to the outside of the fixing pipe. Thereafter, the support rod can be rotated downward so that the support rod and the steering wheel are vertically stored to the side, thereby leaving enough space for the construction operation at the end of the pipeline to be repaired, and there is no need to frequently disassemble and assemble the entire traction steering device, which greatly reduces the workload caused by the disassembly and assembly operation, improves the convenience of using the traction steering device, and ensures the construction efficiency and construction period.

[0013] 2. The sliding column is slidably connected in the fixed tube, and a positioning rod used in conjunction with the sliding column is provided on the fixed tube. In this structure, when the steering wheel performs steering operations on the traction rope, the positioning rod is used to position the sliding column, so that the sliding column cannot continue to slide in the fixed tube, so that the support rod between the two sliding columns remains in a relatively fixed state with the fixed tubes on both sides, thereby making the structure of the steering wheel on the support rod more stable, ensuring the stability and accuracy of the steering operation of the traction rope.

[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0021] Reference Figure 1 and Figure 2The utility model is a traction and steering device for trenchless pipeline repair. The main structure includes a support rod 1 and fixed pipes 2 arranged on both sides of the support rod 1. The support rod 1 extends in the transverse direction. The fixed pipes 2 are used to fix the support rod 1. A fixing plate 3 is welded or bolted to one end of the fixed pipe 2. The fixed plate 3 is provided with a fixing hole 4. Such a structure can pass the bolts through the fixing holes 4 on the fixing plate 3 when used for the first time, so as to fix the fixed pipe 2 on the wall near the pipeline to be repaired, thereby fixing the fixed pipes 2 on both sides. The length of the support rod 1 is less than the distance between the ends of the two fixed pipes 2. Such a structure makes When the support rod 1 is subsequently stored, it can slide laterally into the interior of the fixed tube 2 at one end, thereby leaving space for subsequent storage. The support rod 1 is rotatably connected to a steering wheel 5 through a bearing. The traction rope passes over the steering wheel 5 vertically and then extends laterally into the pipe to be repaired, thereby realizing the steering operation of the traction rope, thereby improving the smoothness of the movement of the traction rope in the pipe to be repaired. The two ends of the support rod 1 are symmetrically rotatably connected to sliding columns 6 through pins or hinges. The sliding columns 6 are slidably connected to the fixed tube 2. The sliding columns 6 can only slide relative to the fixed tube 2. A positioning rod 7 used in conjunction with the sliding columns 6 is provided on the fixed tube 2. The positioning rod 7 is used to After the position of the slide column 6 is fixed, the slide column 6 and the support rod 1 as a whole can no longer slide or rotate relative to the fixed pipe 2. Therefore, the steering wheel 5 on the support rod 1 is more stable when in use. When it is necessary to cut or bundle the repair hose at the end of the pipeline to be repaired, first release the sliding restriction of the positioning rod 7 on the slide column 6, so that the support rod 1 and the slide columns 6 at both ends can slide freely in the fixed pipe 2. At this time, the support rod 1 is slid into the fixed pipe 2 on one side, so that the slide column 6 on the other side slides toward the outside of the fixed pipe 2 until it completely slides out of the fixed pipe 2, and then the support rod 1 is slid in the opposite direction so that the support rod 1 and the slide column The rotation position of 6 is exposed to the outside of the fixed pipe 2, and the positioning rod 7 is used to position the sliding column 6 located inside the fixed pipe 2. Thereafter, the support rod 1 can be rotated downward, so that the steering wheel 5 on the support rod 1 is rotated to the vertical direction, so that it is stored near the end of the pipeline to be repaired, leaving space for the construction operation at the end. Such a structure does not require multiple disassembly and assembly operations of the traction steering device, and only requires horizontal sliding and rotation adjustment of the support rod 1, which greatly reduces the workload of disassembly and assembly operations, improves the convenience of using the traction steering device, saves construction time, improves the overall construction efficiency, and shortens the overall construction period.

[0022] Preferably, refer to Figure 4The fixed tube 2 and the sliding column 6 are both provided with a notch 8, and the notch 8 runs through the side wall of the fixed tube 2. The positioning rod 7 passes through the notch 8 on the fixed tube 2 and enters the notch 8 on the sliding column 6. When the sliding column 6 is positioned, such a structure only needs to move the positioning rod 7 along the radial direction to make it pass through the notch 8 on the fixed tube 2 and enter the notch 8 on the sliding column 6, thereby effectively limiting the position of the sliding column 6 and preventing it from continuing to slide along the axial direction of the fixed tube 2. The structure is simple, and the limiting fixation of the sliding column 6 is more efficient and convenient.

[0023] Preferably, a bracket 9 is welded or bolted to the top of the fixed tube 2, and the top of the positioning rod 7 is rotatably connected to the bracket 9 via a bearing. With this structure, when operating the positioning rod 7, only the positioning rod 7 needs to be rotated to make it pass through the notch 8 on the fixed tube 2 and enter the notch 8 on the sliding column 6. When performing the positioning operation of contacting the positioning rod 7, only the positioning rod 7 needs to be rotated in the opposite direction to disengage it from the notch 8 on the sliding column 6 and the fixed tube 2, thereby making the movement operation of the positioning rod 7 more convenient. The rotatable connection between the top of the positioning rod 7 and the bracket 9 makes it difficult for the positioning rod 7 to be lost after movement, thereby improving the convenience of the positioning operation on the sliding column 6.

[0024] Preferably, the top of the positioning rod 7 is located above the middle of the notch 8. Such a structure enables the positioning rod 7 to maintain a vertical state by its own gravity in the absence of external interference, thereby automatically maintaining the positioning rod 7 in the middle of the notch 8, thereby automatically limiting the position of the sliding column 6, further simplifying the complexity of the device, and ensuring the stability of the overall structure when the steering wheel 5 is in normal use.

[0025] Preferably, refer to Figure 3 A guide bar 10 is symmetrically welded or integrally formed on the inner wall of the fixed tube 2, and a guide groove 11 is symmetrically provided on the side wall of the slide column 6. The guide groove 11 is recessed inward from the surface of the slide column 6, and the guide bar 10 is slidably connected in the guide groove 11. With such a structure, under the sliding cooperation of the guide bar 10 and the guide groove 11, the slide column 6 can only slide in the fixed tube 2, and will not rotate relative to the fixed tube 2, thereby improving the firmness of the slide column 6 when in use, thereby ensuring the stability of the steering wheel 5 in steering the traction rope.

[0026] Preferably, the steering wheel 5 is made of ceramic or metal. Since the steering wheel 5 is generally located at the end of an underground pipeline when in use, which is relatively humid, the ceramic or metal material can have a better corrosion resistance and is not easily corroded and damaged after long-term use, thereby improving the overall service life.

[0027] Working principle: The structure of the utility model utilizes the fixing hole 4 on the fixing plate 3 to fix the fixing pipe 2 near the position of the end of the pipeline to be repaired. When in use, the support rod 1 with the steering wheel 5 utilizes the sliding connection between the sliding columns 6 at both ends and the fixing pipe 2 to achieve support, thereby ensuring the stability of the steering wheel 5 in pulling and steering the traction rope. When performing construction operations at the end of the pipeline to be repaired later, it is only necessary to slide the support rod 1 to one side so that the sliding column 6 at one end slides out of the fixing pipe 2, and then slide the support rod 1 in the opposite direction so that the rotation connection position between the sliding column 6 at the other end and the support rod 1 is exposed to the outside of the fixing pipe 2. Thereafter, the support rod 1 can be rotated downward so that the support rod 1 and the steering wheel 5 are vertically stored to the side, thereby leaving space for construction operations at the end of the pipeline to be repaired. There is enough space and there is no need to frequently disassemble and assemble the entire traction steering device, which greatly reduces the workload caused by the disassembly and assembly operations, improves the convenience of using the traction steering device, and ensures the construction efficiency and construction period; the sliding column 6 is slidably connected in the fixed tube 2, and a positioning rod 7 used in conjunction with the sliding column 6 is provided on the fixed tube 2. In this structure, when the steering wheel 5 performs a steering operation on the traction rope, the positioning rod 7 is used to position the sliding column 6, so that the sliding column 6 cannot continue to slide in the fixed tube 2, so that the support rod 1 between the two sliding columns 6 remains in a relatively fixed state with the fixed tubes 2 on both sides, and then the structure of the steering wheel 5 on the support rod 1 is more stable, ensuring the stability and accuracy of the steering operation on the traction rope.
