Problems solved by technology

[0005] When supporting in a tunnel, it is often necessary to connect several supporting devices to increase the stability of the overall structure; however, due to changes in the width and direction of the tunnel, the traditional supporting devices vary in width and direction When supporting at the bend of the tunnel, it is either inconvenient to connect two adjacent supporting devices, or the tunnel cannot be fully supported. For example, in the above-mentioned patent, when supporting at the bend of the tunnel, the adjacent two supporting devices Effective and reliable connections cannot be obtained between components;

Embodiment 1

[0046] see Figure 1-Figure 5 , a road construction detection support device, including two brackets 1 arranged on the left and right sides, the two brackets 1 are fixedly connected by a connecting beam 3, and the tops of the two brackets 1 are movably provided with an arched beam 2, connected The left and right sides of the beam 3 are provided with side grooves 4, and the inside of the side groove 4 is provided with a threaded cylinder 5. The inner wall of the shaft is threadedly connected with a connecting rod 7, and the end of the connecting rod 7 is fixedly equipped with a vertical cylinder 8, and the top and bottom of the vertical cylinder 8 are respectively provided with a first insertion rod 9 and a second insertion rod 10, and the adjacent support assembly The vertical cylinder 8 is connected with the first insertion rod 9 and the second insertion rod 10 on it. When connecting, the direction of the connection rod 7 can be freely adjusted by the rotation column 6, and t...

Embodiment 2

[0058] see Image 6 with Figure 7 , on the basis of Embodiment 1, the inside of the connecting beam 3 is formed with an inner cavity 31, and the inner cavity 31 is rotated to be provided with a threaded rod 32, and the left and right sides of the outer wall of the threaded rod 32 are respectively provided with first threads with opposite rotation directions. and the second thread, the outer walls of the first thread and the second thread are respectively threaded with a first nut 33 and a second nut 34, and the opposite side of the first nut 33 and the second nut 34 is fixedly equipped with a push rod 35, The end of the push rod 35 is located in the side groove 4 and is fixedly connected with a snap ring 36, the shape of the inner wall of the snap ring 36 is coupled with the shape of the outer wall of the rotating column 6;

[0059] A driven wheel 37 is fixedly installed on the threaded rod 32, and the outer wall of the driven wheel 37 is engaged with a driving wheel 38. The...

Embodiment 3

[0062] see Figure 8 , on the basis of Embodiment 1 or Embodiment 2, several support cylinders 41 are evenly arranged on the top of the connecting beam 3. In this embodiment, three support cylinders 41 are provided, and the inner wall of the support cylinder 41 is provided with sliding plugs 42, the top of the sliding plug 42 is fixed with a support rod 43, the top of the support rod 43 extends to the outside of the support tube 41 and is fixedly connected with the arched beam 2, and the bottom of the outer wall of the support tube 41 is also provided with a one-way air intake valve 44 and manual exhaust valve 45;

[0063] When the top plate 24 and the top column 25 move upwards to drive the arched beam 2 to move upwards, the arched beam 2 can make the sliding plug 42 move upwards in the support cylinder 41 through the support rod 43. At this time, the one-way air intake valve in the support cylinder 41 44 can take in air; when the arched beam 2 is supported, since the manual...

Abstract

The invention relates to the technical field of road construction, and discloses a road construction detection supporting device which comprises a left support and a right support, the two supports are fixedly connected through a connecting beam, side grooves are formed in the left side and the right side of the connecting beam, and threaded cylinders are movably arranged in the side grooves; the top and the bottom of the threaded cylinder are rotationally arranged on the inner wall of the side groove through rotating columns. When adjacent supporting assemblies need to be connected, the direction of the connecting rod can be freely adjusted through the rotating column, the extending length of the connecting rod can be freely adjusted through the threaded cylinder, and therefore the supporting assemblies can be connected at the width changing position and the bending position of the tunnel. And the adjacent supporting assemblies can also be effectively connected. The supporting assembly is novel in design and has the advantage that the supporting assembly can be effectively connected at the width changing position and the bending position of the tunnel.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a road construction detection support device. Background technique [0002] With the development of urban construction, urban road conditions have become increasingly congested; in order to alleviate the pressure of road traffic, we often use tunnels under the road to realize vehicle diversion; after the tunnel is completed, it is often necessary to test the safety of the tunnel , the usual method is to use heavy vehicles to test run on the road to achieve the purpose of tunnel quality inspection. During the inspection process, in order to increase the safety of inspection, support devices are often installed in the tunnel to increase the stability of the tunnel. resistance, prevent collapse; [0003] For example, the Chinese patent announcement number is: the patent of CN213269930U, which just provides a road construction detection support device, including several su...
