Description

Technical Field

[0001] The invention relates to the technical field of pipeline construction in tunnels, and in particular to a pipeline installation device used in a small tunnel. Background Art

[0002] Tunnels are engineering structures buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels. The structure of a tunnel consists of two parts: the main building and auxiliary equipment.

[0003] During tunnel construction, various pipelines are often installed in the tunnel. Pipeline construction in the tunnel usually requires the installation of several support frames in the tunnel to support the pipelines. The overall construction cost is high, the construction efficiency is low, and auxiliary equipment is required to transport the pipelines in the tunnel. In the prior art, the pipeline installation equipment in the tunnel can usually only clamp the two ends of the pipeline during transportation and installation. For longer pipelines, simply clamping the two ends can easily cause the pipeline to bend and deform when it is static. At the same time, there is the disadvantage of unstable clamping at both ends. In addition, the pipelines are usually piled up at the construction site before use. A large amount of impurities are easily adsorbed on the pipe wall of the pipeline. During installation and transportation clamping, it is easy to cause the contact between the clamping part and the pipeline to be not close enough, affecting the subsequent stability.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-Figure 4 The present invention provides a pipeline installation device for a small tunnel, comprising:

[0031] Base 1, moves in the tunnel;

[0032] The clamping assembly includes a movable seat 2, two clamping members and an adjusting member. A slide groove 3 is provided at the top of the base 1. The two movable seats 2 are slidably connected at both ends of the slide groove 3. The two clamping members are respectively arranged at the top of the two movable seats 2 for clamping the two ends of the pipe 4. The adjusting member is arranged in the base 1 for adjusting the distance between the two movable seats 2.

[0033] The auxiliary component includes an auxiliary frame 5 and an auxiliary clamping member. The auxiliary frame 5 is fixedly connected to the middle of the top of the base 1. The auxiliary clamping member is arranged in the auxiliary frame 5 and is transmission-connected to the adjusting member. The auxiliary clamping member is used to auxiliary clamp the pipe 4.

[0034] The cleaning piece is arranged on any clamping piece and is used for cleaning the outer wall of the pipeline 4.

[0035] A further optimized solution is provided in the base 1, and the adjusting member includes two moving blocks 6 slidably connected at both ends of the cavity, a fixed frame 7 is fixedly connected to the top of the moving block 6, and the top of the fixed frame 7 is fixedly connected to the bottom of the moving seat 2, and first tooth plates 8 are fixedly connected to the opposite side walls of the two moving blocks 6, a first rotating shaft 9 is rotatably connected in the cavity, a first gear 10 is fixedly connected to the first rotating shaft 9, the two first tooth plates 8 are arranged in parallel and mesh with the first gear 10 respectively, a first motor 11 is fixedly connected in the cavity, and one end of the first rotating shaft 9 is fixedly connected to the output shaft of the first motor 11.

[0036] In one embodiment of the present invention, referring to Figure 1 The first motor 11 is provided to drive the first gear 10 to rotate. When the first gear 10 rotates, it drives the two meshing first tooth plates 8 to move synchronously in the opposite direction, thereby controlling the synchronous movement of the moving blocks 6 on both sides. On the one hand, it is adapted to pipes 4 of different lengths. On the other hand, when installing the pipe 4, the moving blocks 6 on both sides can be moved toward the middle first to clamp one end of the pipe 4, and then the spacing can be adjusted to finally clamp both ends of the pipe 4, thereby ensuring the stability and horizontality of the pipe 4 after clamping.

[0037] A further optimized solution is provided, wherein the auxiliary clamping member comprises a bidirectional threaded rod 12 rotatably connected to both ends of the auxiliary frame 5, and a movable plate 13 is slidably connected to the top and bottom ends of the auxiliary frame 5, and the two movable plates 13 are respectively threadedly connected to the two ends of the bidirectional threaded rod 12, and one end of a fixed rod 14 is fixedly connected to the opposite sides of the two movable plates 13, and the other end of the fixed rod 14 is fixedly connected to an auxiliary clamping plate 15, and the pipeline 4 is located between the two auxiliary clamping plates 15.

[0038] In one embodiment of the present invention, referring to Figure 2 In the initial state, the pipe 4 is located between the two auxiliary clamping plates 15, and one end of the pipe 4 is clamped. As the two clamping members move, the two auxiliary clamping plates 15 simultaneously shrink toward the middle to clamp the middle of the pipe 4, adapting to the longer-sized pipe 4. Subsequently, the other end is clamped by another clamping member, thereby achieving stable clamping of the two ends and the middle of the pipe 4, avoiding the disadvantages of bending, deformation or instability of the pipe 4 when only the two ends of the longer pipe 4 are clamped.

[0039] To further optimize the solution, the bottom end of the bidirectional threaded rod 12 extends into the cavity and is fixedly connected to a first bevel gear 16 , and both ends of the first rotating shaft 9 are fixedly connected to second bevel gears 17 , and the two first bevel gears 16 are respectively meshed with the two second bevel gears 17 .

[0040] In one embodiment of the present invention, referring to Figure 2 The bidirectional threaded rod 12 is controlled by setting the meshing first bevel gear 16 and the second bevel gear 17, so as to control the two auxiliary clamping plates 15 to move synchronously toward the middle, thereby achieving stable clamping of the middle of the pipe 4.

[0041] A further optimized solution is that the clamping member includes a clamping seat 18 fixedly connected to the top of the moving seat 2, a through hole 19 is opened on the clamping seat 18, a plurality of electric telescopic rods 20 are fixedly connected along the circumferential direction inside the moving seat 2, and the telescopic ends of the electric telescopic rods 20 extend into the through hole 19 and are fixedly connected to a main clamping plate 21.

[0042] In one embodiment of the present invention, referring to Figure 3 The main clamping plate 21 is controlled to contact the pipe wall of the pipe 4 by means of a plurality of electric telescopic rods 20, so as to achieve stable clamping of both ends of the pipe 4.

[0043] A further optimized solution is that the cleaning part includes a turntable 22, which is rotatably connected to any clamping seat 18, and one end of a plurality of cleaning rods 23 are hinged at equal intervals along the circumferential direction in the turntable 22, and a cleaning brush head 24 is fixedly connected to the other end of the cleaning rod 23, and a second tooth plate 25 is fixedly connected to the outer wall of the turntable 22, and a second gear 26 is rotatably connected to the clamping seat 18, and the second gear 26 is meshed with the second tooth plate 25.

[0044] In one embodiment of the present invention, referring to Figure 4 A torsion spring (not shown in the figure) is arranged between the cleaning rod 23 and the turntable 22, and the two ends of the torsion spring are fixedly connected to the cleaning rod 23 and the turntable 22 respectively. The torsion spring is arranged to ensure the stable contact between the cleaning brush head 24 and the outer wall of the pipe 4. The second gear 26 is controlled to rotate by a separate driving motor (not shown in the figure). Subsequently, the rotation of the second gear 26 drives the meshing second tooth plate 25 to rotate, thereby controlling a plurality of cleaning brush heads 24 to remove impurities adsorbed on the outer wall of the pipe 4, thereby ensuring the stable contact between the subsequent main clamping plate 21 and the auxiliary clamping plate 15 and the pipe wall of the pipe 4.

[0045] A further optimized solution is that the movable seat 2 includes a slider 201, which is slidably connected in the slide groove 3. The top of the slider 201 is fixedly connected to a fixed groove 202, and a lifting block 203 is slidably connected in the fixed groove 202.

The bottom end of the fixed groove 202 is rotatably connected to a second rotating shaft 27, and the top of the second rotating shaft 27 is fixedly connected to a threaded rod 28, which is threadedly connected to the bottom end of the lifting block 203, and the bottom end of the second rotating shaft 27 extends into the cavity and is connected to the fixed frame 7.

[0046] In one embodiment of the present invention, referring to Figure 1 The fixed groove 202 slides in the slide groove 3 through the slider 201. When the second rotating shaft 27 rotates, the threaded rod 28 drives the threaded lifting block 203 to move vertically in the fixed groove 202, thereby adjusting the height of the lifting block 203.

[0047] A further optimized solution is that a third rotating shaft 29 is rotatably connected in the fixed frame 7, a third bevel gear 30 is fixedly connected to the third rotating shaft 29, the bottom end of the second rotating shaft 27 extends into the fixed frame 7 and is fixedly connected to a fourth bevel gear 31, and the third bevel gear 30 is meshed with the fourth bevel gear 31.

[0048] In one embodiment of the present invention, referring to Figure 1 The third rotating shaft 29 is synchronously controlled by the meshing third bevel gear 30 and the fourth bevel gear 31, thereby adjusting the clamping height of the clamps at both ends to ensure the horizontality of the pipe 4 after subsequent clamping.

[0049] A further optimized solution is that the two third rotating shafts 29 are respectively fixedly connected with a telescopic tube 32 and a telescopic rod 33, the telescopic tube 32 and the telescopic rod 33 are slidably connected, one of the fixed frames 7 is fixedly connected with a second motor 34, and one end of the third rotating shaft 29 is fixedly connected to the output shaft of the second motor 34.

[0050] In one embodiment of the present invention, referring to Figure 1 The cross-sections of the telescopic tube 32 and the telescopic rod 33 are both rectangular.

[0051] According to a further optimization scheme, movable wheels 35 are installed on the four corners of the bottom end of the base 1.

[0052] In one embodiment of the present invention, referring to Figure 1 The movable wheels 35 are provided to enable the entire device to be moved in a small tunnel, thereby realizing the transportation of the pipeline and ensuring the subsequent installation efficiency.
