Description

Technical Field

[0001] The utility model relates to the technical field of pipe pulling construction, in particular to a pipe pulling back auxiliary device for pipe pulling construction. Background Art

[0002] Pipe pulling is to cut a groove to put the pipe in, then drill a hole and use a tractor to drag the pipe over on the other side. Generally, the pipe is welded and formed once before construction. Pipe pulling construction is a common pipeline installation method. It refers to the use of special pipe pulling machines and hooks to easily pull the prefabricated pipes into the ground along the arranged well point line or the ground pipeline layout line, so as to achieve rapid connection of the pipes within a certain length range.

[0003] In pipe pulling construction, pulling back the pipe is one of the key steps. In the pipe pulling construction of water conservancy, municipal engineering and other projects, the pipe will produce greater resistance during the pulling back process due to its own weight and construction distance. The traditional approach is to use hydraulic power to form a sending ditch around the pipe, and reduce friction resistance by flushing with water, thereby assisting the pulling back of the pipe.

[0004] However, although the traditional hydraulic transmission ditch auxiliary method can reduce resistance to a certain extent, it consumes a large amount of soil during the construction process, which can easily cause pollution to the surrounding environment. In addition, the hydraulic transmission method requires a large amount of water, which will cause waste of resources. At the same time, the strong scouring effect may cause damage to the pipe wall, thereby affecting the subsequent construction quality. For this reason, the utility model provides a pipe pulling construction pipe back pulling auxiliary device to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figures 1 to 3 The utility model provides a pipeline pulling back auxiliary device for pipe pulling construction, including a base 1, two guide rail bodies 2 slidably connected to the top of the base 1, a sliding seat 3 slidably connected between the tops of the two guide rail bodies 2, a fixing adjustment mechanism 4 arranged on the top of the base 1 for fixing and adjusting effects, a mounting frame 5 fixed to the top of the base 1, a plurality of rollers 6 rotatably connected to the inside of the mounting frame 5, and a driving component 7 arranged inside the guide rail body 2.

[0033] Through the coordinated use of the base 1, the guide rail body 2, the sliding seat 3, the fixed adjustment mechanism 4 and the driving assembly 7, in actual use, the pipeline can be effectively fixed and the pipeline can be pulled back, which simplifies the operation process and improves construction efficiency and safety. A buffering structure is also provided to reduce the impact force on the pipeline during the pulling back process, thereby increasing the service life of the pipeline. The inclination angle of the guide rail can also be effectively adjusted to adapt to different construction environments, thereby improving the practicability of the pipeline pulling back auxiliary device in pipe pulling construction.

[0034] In this embodiment, the fixing and adjusting mechanism 4 is a structure for achieving both fixing and adjusting effects.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, the fixed adjustment mechanism 4 includes two fixed blocks 401 slidably connected to the top of the sliding seat 3, a fixed component 402 arranged inside the fixed block 401 for fixing the pipeline, a damper 403 fixed to the bottom of the fixed block 401, a shock-absorbing spring 404 fixed to the bottom of the fixed block 401, a shock-absorbing pad 405 fixed to the bottom of the fixed block 401 and an adjustment component 406 arranged inside the base 1 for adjusting the inclination angle of the guide rail body 2.

[0036] It should be noted that the fixing assembly 402 includes a fixing cylinder 4021 slidably connected to the inside of the fixing block 401, a first screw 4022 threadedly connected to the inside of the fixing cylinder 4021, a rotating block 4023 respectively fixed to the opposite ends of the two first screws 4022, an arc-shaped clamping plate 4024 respectively fixed to the opposite ends of the two first screws 4022, a rubber plate 4025 fixed to the inside of the arc-shaped clamping plate 4024, two limit blocks 4026 respectively fixed to the top and bottom of the fixing cylinder 4021, four limit grooves 4027 opened in the fixing block 401, and two adjustment grooves 4028 respectively opened on the opposite sides of the two fixing blocks 401, which are used to effectively fix the pipeline being pulled back.

[0037] In addition, the adjustment component 406 includes a fixed rod 4061 fixed inside the base 1, an adjustment cylinder 4062 slidably connected to the outside of the fixed rod 4061, a connecting block 4063 fixed to the top of the adjustment cylinder 4062 and two hydraulic rods 4064 fixed inside the base 1, which are used to adjust the inclination angle of the guide rail body 2.

[0038] Among them, the limiting groove 4027 is connected with the adjusting groove 4028 to ensure that the limiting block 4026 can effectively slide in the limiting groove 4027. The diameter of the adjusting groove 4028 is equal to the outer diameter of the fixing tube 4021, so that the fixing tube 4021 can slide in the adjusting groove 4028 more stably.

[0039] At the same time, the top of the connecting block 4063 is fixed to the bottom of the guide rail body 2, and the top of the connecting block 4063 is fixed to the bottom of the mounting frame 5, ensuring that the guide rail body 2 is more stable when the angle is adjusted under the action of the connecting block 4063, the adjustment tube 4062 and the fixing rod 4061.

[0040] It can be understood that a battery 8 is fixed to the top of the base 1, and the top of the hydraulic rod 4064 is hinged to the guide rail body 2 through a hinge seat, ensuring that the inclination angle of the guide rail body 2 can be adjusted through the hydraulic rod 4064, and the left and right sides of the mounting frame 5 are respectively fixed to the opposite sides of the two guide rail bodies 2, and the top of the roller 6 is in close contact with the bottom of the sliding seat 3, so that the mounting frame 5 is installed more stably and the sliding seat 3 can slide more stably through the roller 6.

[0041] In addition, the bottoms of the damper 403 and the shock absorbing spring 404 are fixed to the sliding seat 3 to ensure that the damper 403 and the shock absorbing spring 404 can achieve a shock absorbing effect. A slot 31 is provided on the top of the sliding seat 3 to fix the pipeline. The adjustable distance of the limit block 4026 in the limit slot 4027 is smaller than the adjustable distance of the first screw 4022 in the fixed cylinder 4021, which effectively avoids the first screw 4022 and the fixed cylinder 4021 from falling off during the adjustment process.

[0042] In addition, the driving assembly 7 includes a slider 701 slidably connected to the inside of the guide rail body 2, a second screw 702 threadedly connected to the inside of the slider 701, and a motor 703 fixed to the back of the second screw 702, which drives the sliding seat 3 to slide on the guide rail body 2 to achieve the back-dragging of the pipeline.

[0043] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of batteries is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0044] The working principle of the above embodiment is:

[0045] When in use, the device is first fixed at the location where it is needed through the base 1, and then the pipe to be pulled back is placed in the slot 31 provided on the sliding seat 3, and the two rotating blocks 4023 are rotated at the same time to drive the first screw 4022 to rotate in place, and the fixing cylinder 4021 is adjusted to move left and right inside the fixing block 401 under the thrust of the internal thread rotation and the limiting action of the limiting block 4026, thereby driving the arc clamping plate 4024 and the rubber plate 4025 to move left and right, and the pipe can be effectively fixed by the arc clamping plate 4024 and the rubber plate 4025, and then the motor 703 is turned on to drive the second screw 702 to rotate, so that the slider 701 is pushed by the internal thread rotation. Under the action of force, the guide rail body 2 is moved forward and backward inside to adjust, thereby driving the sliding seat 3 and the pipeline to move forward and backward to adjust, so as to realize the dragging of the pipeline, and under the action of the damper 403, the shock-absorbing spring 404 and the shock-absorbing pad 405, it can effectively achieve the shock-absorbing effect, thereby effectively reducing the impact force on the pipeline, and under the action of the mounting frame 5 and the roller 6, the sliding seat 3 is installed more stably, and then, when it is necessary to adjust the inclination angle of the guide rail body 2, the hydraulic rod 4064 is opened, so that the guide rail body 2 is rotated on the outside of the fixed rod 4061 through the adjusting cylinder 4062 under the action of the hydraulic rod 4064, so as to adapt to the needs of different construction environments.
