Specific embodiments
[0020] The present utility model will be further described below with reference to the accompanying drawings.
[0021] The orientations referred to in this specification are based on the orientations when a pipe well construction auxiliary device of the present utility model is working properly, without limiting its orientations during storage and transportation, only representing relative positional relationships and not absolute positional relationships.
[0022] As Figure 1 and Figure 2 collectively shown, a pipe well construction auxiliary device includes a support frame 1, a guiding device and a clamping device installed on the support frame 1. A lower pipe channel 11 is provided on the support frame 1, and the pipe 2 is lowered into the pipe well from the lower pipe channel 11.
[0023] The guiding device includes a plurality of guide rollers 32 rotatably installed on the support frame 1. The plurality of guide rollers 32 are arranged around the periphery of the lower pipe channel 11 and are clamped in the circumferential direction of the pipe 2, and the guide rollers 32 roll along the outer sidewall of the pipe 2. When the pipe 2 needs to be lowered, the device is fixed above the pipe well in advance, and the lower pipe channel 11 is aligned with the pipe well; the crane hoists the upper end of the pipe 2, and the lower end of the pipe 2 is inserted into the lower pipe channel 11. The pipe 2 is clamped between the plurality of guide rollers 32, and as the pipe 2 is lowered, the guide rollers 32 roll along the sidewall of the pipe 2, thereby realizing the guiding effect on the pipe 2.
[0024] In order to achieve stable support and ensure the guiding stability of the guide rollers 32, at least two layers of guide rollers 32 are installed up and down. In this embodiment, two layers of guide rollers 32 are installed up and down; the two layers of guide rollers 32 can achieve stable clamping of the pipe 2 and prevent the guide rollers 32 from shaking during the lowering process.
[0025] Further, in order to facilitate the adjustment of the clamping force between the guide roller 32 and the pipe 2 and prevent the pipe 2 from being damaged due to excessive extrusion pressure, the guiding device further includes V-shaped frames 3 that are relatively slidably mounted on the support frame 1 and are located on both sides of the pipe 2, and a sliding driving device 31 that drives the two V-shaped frames 3 to slide relatively or away from each other; the guide rollers 32 are rotatably mounted on the inclined walls 33 on both sides of the V-shaped frames 3; since there are two layers of guide rollers 32 arranged vertically, at least two layers of guide rollers 32 are vertically mounted on each inclined wall 33.
[0026] The support frame 1 is provided with a slideway 12 for the V-shaped frame 3 to slide, and two sliders are slidably mounted on the slideway 12, and each slider is fixed on the side of a V-shaped frame 3. The sliding driving device 31 drives the two V-shaped frames 3 to slide relatively or away from each other, thereby adjusting the size of the pipe-laying channel 11 and the clamping force between the guide roller 32 and the pipe 2. The sliding driving device 31 can adopt a cylinder or an electric cylinder, and cooperate with structures such as a connecting rod to achieve clamping. In this embodiment, the sliding driving device 31 includes a lead screw 311 rotatably mounted on the support frame 1, and two sections of lead screw threads with opposite helix directions are symmetrically arranged on the lead screw 311, and each slider is screwed on a different lead screw thread; one end of the lead screw 311 is fixedly installed with a first handwheel 312. By rotating the first handwheel 312, the lead screw 311 is driven to rotate, thereby driving the two sliders to move relatively or away from each other, and then driving the two V-shaped frames 3 to slide relatively or away from each other. In order to achieve stable sliding, two slideways 12 are provided, which are respectively located on the upper and lower sides of the V-shaped frame 3, and the lead screw 311 is located between the two slideways 12.
[0027] The clamping device includes clamping plates 41 that are horizontally slidably mounted on the support frame 1 and are evenly distributed in the circumferential direction of the pipe 2, and a clamping driving device that drives the clamping plates 41 to clamp or loosen the pipe 2.
[0028] Since there are two layers of guide rollers 32 in this embodiment, in order to achieve stable supporting force, the clamping device is located between the two layers of guide rollers 32. The clamping driving device includes a screw rod 42 screwed on the support frame 1 and the inner end of which is rotatably mounted on one side of the clamping plate 41, and a second handwheel 43 is fixed on the outer end of the screw rod 42. Guide rods 44 are also fixedly installed on both sides of the clamping plate 41 where the screw rod 42 is located, and guide holes are provided on the V-shaped frame 3 corresponding to the guide rods 44, so as to realize the limited sliding of the clamping plate 41. By rotating the second handwheel 43, the rotation of the screw rod 42 is realized, and then the position of the clamping plate 41 is adjusted, and the clamping plate 41 is pressed against the pipe 2 to realize the clamping of the pipe 2.
[0029] In this embodiment, there are two clamping plates 41, which are respectively located on both sides of the pipeline 2, and the clamping plates 41 are arc-shaped plates, and their radian is the same as that of the pipeline 2, so as to increase the contact area with the pipeline 2. Since the clamping plates 41 need to bear the gravity of the pipeline 2, in order to avoid the force deformation of the screw 42, the bottom of the clamping plate 41 is supported on the support frame 1, so as to avoid the clamping plate 41 from being suspended and increase the bottom support.
[0030] In order to increase the friction between the clamping plate 41 and the pipeline 2 and prevent the pipeline 2 from falling off, a rubber layer 411 is attached to the contact surface of the clamping plate 41 with the pipeline 2.
[0031] In order to facilitate the movement of this device, a platform trolley 5 is further included. The support frame 1 is fixedly installed on the platform trolley 5, and an avoidance opening corresponding to the pipe-laying channel 11 is provided at the bottom of the platform trolley 5.
[0032] As Figure 1 、 Figure 2 and Figure 3 collectively shown, the working process of an auxiliary device for pipe well construction of the present utility model is as follows:
[0033] When the pipeline 2 needs to be lowered, this device is fixed above the pipe well in advance, and the pipe-laying channel 11 is aligned with the pipe well; the size of the pipe-laying channel 11 is adjusted according to the pipeline diameter; the crane hoists the upper end of the pipeline 2, and the lower end of the pipeline 2 is extended into the pipe-laying channel 11. The pipeline 2 is clamped between a plurality of guide rollers 32, and as the pipeline 2 is lowered, the guide rollers 32 roll along the side wall of the pipeline 2, thus realizing the guiding effect on the pipeline 2.
[0034] When pipe connection is required, by rotating the second hand wheel 43, the rotation of the screw 42 is realized, and then the position of the clamping plate 41 is adjusted to press the clamping plate 41 against the pipeline 2 to realize the clamping of the pipeline 2. After the pipe connection is completed, rotate the second hand wheel 43 in the reverse direction to realize the retraction of the clamping plate 41.
[0035] An auxiliary device for pipe well construction of the present utility model solves the technical problems in the prior art that during the pipe well construction process, the lowering of the pipeline is likely to cause contact with the side wall of the pipe well, resulting in the falling of soil, and at the same time, during the pipe connection process, it is inconvenient to fix the pipeline. The present utility model realizes the guiding effect during the pipeline lowering process and the clamping effect during the pipeline connection process by setting a guiding device and a clamping device, which is convenient for workers to construct, reduces the labor intensity of workers, and improves the construction efficiency at the same time.
[0036] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present utility model should also belong to the protection scope of the present utility model.
