The embodiment of the utility model provides a strutting arrangement for be used for tunnel lining to detect radar. Referring to fig. 1 and 2, the supporting device for a tunnel lining detection radar includes a moving vehicle 10, a strut 20, a support ring 21, a detection rod 30, an adjustment seat 41, an adjustment shaft 42, a worm wheel 43, an adjustment rod 31, and a radar box 50. The mobile vehicle 10 is provided with shock-absorbing wheels 11. The bottom of the strut 20 is connected to the mobile cart 10. A buttress ring 21 is attached to the top of the strut 20. The detection rod 30 is inserted into the support ring 21 and is configured to rotate in a vertical plane with the support ring 21 as a fulcrum. The sensing lever 30 is provided with a through hole. The axial direction of the through hole is parallel to the axial direction of the detection rod 30.
The adjustment seat 41 is connected to a first end of the detection lever 30. The adjusting shaft 42 is rotatably connected with the adjusting seat 41. The worm wheel 43 is connected to the adjusting shaft 42 and is used for rotating the adjusting shaft 42. The adjusting rod 31 is inserted into the through hole and is rotatably connected with the detecting rod 30. The first end of the adjusting rod 31 is rotatably connected with the adjusting seat 41, and is provided with a thread for matching with the worm wheel 43, so as to drive the worm wheel 43 to rotate. The radar box 50 is connected to the adjustment shaft 42 and is configured to rotate by the adjustment shaft 42. The radar box 50 is provided with a housing chamber 501 for housing a detection radar.
When in use, the mobile vehicle 10 is pushed to the detection position; then the detection rod 30 is passed through the branch ring 21; then, the detection radar is placed in the accommodating cavity 501 of the radar box 50; next, an operator holds the second end of the detection rod 30 by hand, and rotates the detection rod 30 by taking the support ring 21 as a fulcrum, so that the radar box 50 at the first end of the detection rod 30 is close to the tunnel lining; then, the second end of the adjusting rod 31 is rotated, and the first end of the adjusting rod 31 is provided with threads, so that the adjusting rod 31 drives the worm wheel 43 to rotate, the worm wheel 43 drives the adjusting shaft 42 to rotate, and the adjusting shaft 42 drives the radar box 50 to rotate, so that the detection radar is attached to the tunnel lining; finally, the operator holds the second end of the detection rod 30, makes the detection radar always attached to the tunnel lining, and pushes the moving vehicle 10 at a constant speed, so that the detection of the tunnel lining can be completed.
In the prior art, there are also two solutions: firstly, adopt the mode that operation vehicle and support combined together, through height and the angle of adjusting the support, make radar laminating lining cutting, operation vehicle drives the support and removes to detect. However, in actual construction, when the lining is detected, the tunnel floor is not hardened, so the floor is uneven, and generally has sundries such as stones and soil blocks, and the working vehicle inevitably jolts during running, so the radar cannot always adhere to the lining, and data failure occurs, and therefore, the method is not suitable for actual use. And the operating vehicle has high use cost, and the bracket has complex structure and high processing cost, so the bracket is not suitable for practical use.
The other scheme is that a detector holds the support in a hand, the radar is attached to the lining by adjusting the height and the angle of the support, and an operator moves at a constant speed to detect. However, since the height of the vault of the lining is generally 3 meters to 8 meters, and the height of the arch waist is generally 2 meters to 6 meters, the height of the support is large, so that a detector needs to hold the support and look up to make the radar attach to the lining, and needs to keep moving at a constant speed, and the operation difficulty is large. In addition, the arms of the detection personnel need to bear the whole weight of the detection radar and the support, fatigue is easy to occur, and once the arms are unstable, the radar and the lining are not completely attached, data failure can be caused.
In this embodiment, the mobile vehicle 10 is provided with the damping wheels 11, which can counteract the influence caused by a part of jolts; in addition, the detection personnel can make the radar adhere to the lining by holding the detection rod 30, when bumping occurs, the personnel can exert subjective activity, and the radar and the lining are always kept in an adhering state by manual adjustment. In addition, in the embodiment, the weight of the detection radar, the detection rod 30, the radar box 50 and other structures can be shared by using the lever principle and the support ring 21 as the fulcrum of the detection rod 30; in addition, in the embodiment, the force application direction of the person is changed, and the detection person can keep the radar in the fit state with the lining by pressing down the second end of the detection rod 30 and applying a small axial force; moreover, through adjusting the hookup location of test rod 30 and braced ring 21, can utilize lever principle to reach laborsaving effect, test rod 30 slope sets up moreover, reduces the angle that personnel face upward the head, and the personnel of being convenient for observe.
In conclusion, the embodiment can enable the detection personnel to complete the operation on the ground, and is time-saving and labor-saving. Moreover, each part can be manufactured by utilizing leftover materials of a construction site, and the parts such as the damping wheel 11, the worm wheel 43 and the like are convenient to purchase, so that the supporting device is low in manufacturing cost, convenient and fast to operate and suitable for practical use.
In addition, in the prior art, the radar box 50 needs to be lowered to the ground, the angle of the radar box 50 needs to be adjusted, and then the radar box is raised to the air, the angle of the radar box 50 can be adjusted only by frequently repeating the process, so that the radar is attached to the lining, and the adjustment process is time-consuming and labor-consuming. In the embodiment, the angle of the radar box 50 can be adjusted by rotating the adjusting rod 31 at the hand-held end of the detection personnel, so that time and labor are saved; moreover, the adjusting rod 31 is equivalent to a worm, the transmission mode of the worm gear has a self-locking function, and after the adjustment is completed, the angle of the radar box 50 is kept unchanged, so that the operation is convenient and fast.
