Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and in particular relates to an adjustable longitudinal drainage pipe positioning device for a highway tunnel. Background Art

[0002] Highway tunnels are passages for automobile transportation. With the development of social economy and production, a large number of highways have emerged, which put forward higher standards for road construction technology, requiring straight lines, gentle slopes, and wide roads. Therefore, when roads pass through mountainous areas, the previous winding schemes are mostly changed to tunnel schemes. The construction of tunnels plays an important role in improving the technical status of highways, shortening the operating distance, increasing transportation capacity, and reducing accidents. When the drainage pipe is longitudinally positioned, it is often necessary to install a clamp on the wall, and then pass the pipe through the clamp. Once the position of the clamp on the wall is fixed, it cannot be adjusted in time. If the pipe needs to be raised or lowered, the clamp needs to be reinstalled on the wall. The installation efficiency of the drainage pipe is low. Therefore, the inventor proposes an adjustable longitudinal drainage pipe positioning device for a highway tunnel. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] This specific implementation is a road tunnel adjustable longitudinal drainage pipe positioning device, and its structural schematic diagram is as follows Figure 1 As shown, it includes a fixed column 1, a fixed mechanism 3 and a lifting groove 2. The fixed column 1 is vertically provided with a lifting groove 2, and the fixed mechanism 3 is movably installed at the lifting groove 2; the lifting groove 2 is vertically provided along the surface of the fixed column 1.

[0024] Reference Figure 2 The fixing mechanism 3 includes a lifting block 5, a lifting rod 9, a fixing plate 7 and a hoop 11. The lifting block 5 is adapted to be slidably installed with the lifting slot 2. The hoop 11 is fixed to the end of the lifting rod 9 away from the lifting block 5. The fixing plate 7 is fixedly arranged on the outer wall of the lifting rod 9, and a pull block 8 is elastically inserted into the fixing plate 7. The side of the fixing plate 7 away from the clamping block is fixedly connected to the outer frame 6, and a rotating disk 12 is rotatably installed inside the outer frame 6. The upper end of the hoop 11 is fixedly connected to a connecting column 10, and the connecting column 10 is threadedly connected to the lifting rod 9.

[0025] Reference Figure 3 , multiple groups of tooth blocks 17 are distributed around the outer wall of the rotating disk 12, and the multiple groups of tooth blocks 17 are spaced apart from each other. One end of the pull block 8 inserted toward the inside of the fixed plate 7 is fixedly connected to the limiting insertion strip 15, and the limiting insertion strip 15 is inserted into the gap between the multiple groups of tooth blocks 17. Pulling the pull block 8 causes the pull block 8 to drive the moving block 13 toward the inner wall of the fixed plate 7, and the elastic member 14 contracts under force, and the pull block 8 drives the limiting insertion strip 15 to leave the gap between the tooth blocks 17. After the tooth blocks 17 lose their limit, the rotating disk 12 can rotate.

[0026] Reference Figure 4 , a moving block 13 is symmetrically installed on the outer wall of one end of the pull block 8 located inside the fixed plate 7, and the moving block 13 is fixedly connected to the pull block 8. An elastic member 14 is fixedly connected to the surface of the moving block 13 facing the inner wall of the fixed plate 7, and the other end of the elastic member 14 is fixedly connected to the inner wall of the fixed plate 7. Connecting tooth grooves 16 are arranged at intervals on the outer surface of the fixed column 1, and the connecting tooth grooves 16 are adapted to the tooth block 17. Even if the height position of part of the pipeline needs to be adjusted later, there is no need to remove the clamp 11. It is only necessary to adjust the position of the lifting rod 9 when the pipeline is disconnected and movable, and fix it at any position through the cooperation of the limiting insert 15 and the tooth block 17, which is convenient to operate.

[0027] Working principle: When in use, first fix the fixed column 1 to the wall in the tunnel, then connect the clamp 11 to the lifting rod 9 through the connecting column 10. The clamp 11 can be replaced and selected in size according to the use requirements. After the clamp 11 is fixed, the position of the clamp 11 can be adjusted according to the installation height of the water pipe, and the pull block 8 is pulled so that the pull block 8 drives the moving block 13 to approach the inner wall of the fixed plate 7. The elastic member 14 is forced to shrink, and the pull block 8 drives the limiting insert 15 to leave the gap of the tooth block 17. After the tooth block 17 loses its limit, the rotating disk 12 can rotate, and at this time, the lifting rod 9 is pushed, and the lifting rod 9 The lifting block 5 is driven to slide vertically along the lifting groove 2, and the corresponding position is adjusted on the fixed column 1, and then the pulling of the pulling block 8 is released, the elastic member 14 is reset, and the movable block 13 is driven back to its original position, and the pulling block 8 reinserts the limiting insert 15 between the tooth blocks 17, and then the lifting rod 9 is limited and fixed. At this time, the drainage pipe is inserted into the clamp 11 for fixing. Even if the height position of part of the pipeline needs to be adjusted later, there is no need to remove the clamp 11. It is only necessary to adjust the position of the lifting rod 9 when the pipeline is disconnected and movable, and fix it at any position through the cooperation of the limiting insert 15 and the tooth block 17. It is convenient to operate and easy to use.
