Technical Field

[0001] This utility model relates to the field of waterproof testing technology, specifically to a tunnel waterproof performance testing device. Background Technology

[0002] A highway tunnel is an underground passage specifically designed and built for automobile transportation. It traverses mountains, hills, cities, or other geographical obstacles to achieve direct road connections, shorten travel distances, improve transportation efficiency, and avoid the use of complex and unsafe mountain roads due to terrain limitations.

[0003] Among them, announcement number CN222480085U discloses a testing device for the waterproof performance of highway tunnels, including a remote control chassis. A testing host is fixedly installed on the top of the remote control chassis. A fine-tuning mechanism is fixedly installed on the top of the testing host. A telescopic mechanism is fixedly installed on the top of the fine-tuning mechanism. A testing component is fixedly installed on the top of the telescopic mechanism. The telescopic mechanism includes a mounting sleeve. A telescopic rod is movably installed inside the mounting sleeve. A connecting rod is movably installed inside the telescopic rod. A locking mechanism is movably installed inside the telescopic rod. Locking mechanisms are fixedly installed on the tops of both the mounting sleeve and the telescopic rod. During testing, the telescopic rod and the connecting rod are pulled out from inside the mounting sleeve and the telescopic rod. The overall length of the telescopic mechanism is adjusted. After adjustment, the positions of the telescopic rod and the connecting rod are fixed by the locking mechanism. The testing component is then fixed on the top of the connecting rod for testing.

[0004] The device adjusts the height of the testing equipment by pulling out the telescopic rod and connecting rod and then using a screw. The adjustment process is cumbersome and the testing efficiency is low. In addition, due to the large weight of the testing equipment, the single-rod support method has low stability, which affects the testing accuracy of the equipment.

[0005] Therefore, it is necessary to invent a tunnel waterproofing performance testing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a tunnel waterproofing performance testing device to solve the problems of cumbersome adjustment process, low testing efficiency, low stability of single-rod support, and impact on equipment testing accuracy.

[0016] By adopting the above technical solution, as the transmission rod slides to the right, it drives the left side of the lower end of the scissor arm to move to the right, thereby unfolding the scissor arm upwards, and conversely, folding the scissor arm downwards.

[0017] Optionally, a second screw is rotatably connected to the middle position of the inner side of the adjustment frame, and linear guide rails are fixedly connected to both the front and rear sides of the second screw on the inner side of the adjustment frame.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figures 1 to 4The tunnel waterproofing performance testing device shown includes a mobile vehicle 1. A lifting bracket 2 is installed on the upper side of the mobile vehicle 1. The lifting bracket 2 includes a supporting base plate 21, a fixing frame 211, a positioning groove 212, a first screw 213, a first motor 214, a transmission rod 215, a first support block 216, a scissor arm 22, a supporting top plate 23, a limiting rod 231, a transmission block 232, and a second support block 233. An adjusting frame 3 is fixedly installed on the upper side of the supporting top plate 23. A mounting plate 34 that can slide left and right is provided on the upper side of the adjusting frame 3. A testing device 37 is fixedly installed on the upper side of the mounting plate 34. Multiple sets of lighting devices 38 are fixedly connected to the front and rear sides of the upper surface of the supporting top plate 23.

[0036] The scissor arm 22 is composed of multiple intersecting rods connected by hinge points to form a foldable "X"-shaped structure. During use, the detection device 37 is moved to below the detection point by the moving vehicle 1. Then, the first motor 214 drives the transmission rod 215 to slide upward, unfolding the scissor arm 22 and pushing the supporting top plate 23 upward, quickly lifting the detection device 37 to the detection point, thus improving detection efficiency. At the same time, multiple sets of lighting devices 38 can be turned on during the detection process to illuminate the detection point, making it easier for staff to observe the detection point.

[0037] See Figure 3 and Figure 4 The support base plate 21 is fixedly connected to the upper surface of the moving vehicle body 1. The fixed frame 211 is fixedly connected to the left side of the upper surface of the support base plate 21. Positioning grooves 212 are provided on both the front and rear surfaces of the fixed frame 211. The front and rear ends of the transmission rod 215 are slidably connected to the front and rear positioning grooves 212 respectively. The two ends of the first screw 213 are rotatably connected to the inner walls of the left and right sides of the fixed frame 211 respectively. The first motor 214 is fixedly installed on the right side of the fixed frame 211. The output end of the first motor 214 is fixedly connected to the right end of the first screw 213. The first screw 213 is threadedly connected to the middle of the transmission rod 215. The upper surface of the support base plate 21... Two sets of first support blocks 216 are fixedly connected to the right side of the support plate 23. Two sets of front and rear limiting rods 231 are fixedly connected to the left side of the lower surface of the support plate 23. Transmission blocks 232 are slidably connected to the surfaces of the two sets of limiting rods 231. Two sets of second support blocks 233 are fixedly connected to the right side of the lower surface of the support plate 23. The left side of the lower end of the scissor arm 22 is rotatably connected to the front and rear ends of the transmission rod 215 respectively. The right side of the lower end of the scissor arm 22 is rotatably connected to the two sets of first support blocks 216 respectively. The left side of the upper end of the scissor arm 22 is rotatably connected to the two sets of transmission blocks 232 respectively. The right side of the upper end of the scissor arm 22 is rotatably connected to the two sets of second support blocks 233 respectively.

[0038] Specifically, the output end of the first motor 214 drives the first screw 213 to rotate clockwise. The first screw 213 drives the transmission rod 215 to slide to the right, thereby driving the left side of the lower end of the scissor arm 22 to move to the right. Since the right side of the lower end of the scissor arm 22 is fixed, the scissor arm 22 will unfold upwards, thereby lifting the support plate 23 upwards. At this time, the left side of the upper end of the scissor arm 22 will drive the transmission block 232 to slide to the right on the surface of the limit rod 231. At the same time, the upper and lower ends of the scissor arm 22 rotate around the transmission block 232, the second support block 233, the transmission rod 215 and the first support block 216 respectively.

[0039] In addition, after the test is completed, the output end of the first motor 214 drives the first screw 213 to rotate counterclockwise. The first screw 213 drives the transmission rod 215 to slide to the left, which in turn drives the left side of the lower end of the scissor arm 22 to move to the left. At this time, the scissor arm 22 will fold down and move the support plate 23 down. When the scissor arm 22 is fully folded, the height of the support plate 23 can be effectively reduced, which facilitates the movement and transfer of the equipment and improves the convenience of equipment transportation.

[0040] See Figure 5 and Figure 6 A second screw 32 is rotatably connected to the middle of the inner side of the adjusting frame 3. Linear guide rails 31 are fixedly connected to both the front and rear sides of the second screw 32 on the inner side of the adjusting frame 3. A second motor 33 is fixedly installed on the right side of the adjusting frame 3. The output end of the second motor 33 is fixedly connected to the right end of the second screw 32. A first connecting block 35 is fixedly connected to both the front and rear sides of the lower surface of the mounting plate 34. The first connecting block 35 is slidably connected to the linear guide rail 31. A second connecting block 36 is fixedly connected to the middle of the lower surface of the mounting plate 34. The second connecting block 36 is threadedly connected to the second screw 32.

[0041] Meanwhile, when the supporting top plate 23 is moved to the top for testing, and when testing is required around the testing point, directly moving the moving vehicle 1 may cause the testing equipment 37 to shake due to factors such as terrain, affecting the testing accuracy. At this time, the second motor 33 can be started. The output end of the second motor 33 drives the second screw 32 to rotate. During the rotation of the second screw 32, it cooperates with the second connecting block 36 to drive the mounting plate 34 to slide left and right on the surface of the linear guide rail 31, thereby adjusting the position of the testing equipment 37. This can improve the stability of the testing equipment 37 during the adjustment process and improve the testing accuracy of the testing equipment 37.

[0042] The working principle of this utility model is as follows: By using the first motor 214 and the first screw 213 to drive the scissor arm 22 to fold or unfold, the supporting top plate 23 can be raised and lowered, which can quickly raise the height of the detection device 37 to the detection position, effectively improving the adjustment speed and thus improving the detection efficiency. At the same time, the cross structure of the scissor arm 22 effectively improves the stability of the detection device 37 during the lifting and detection process, and improves the detection accuracy. Meanwhile, by using the second motor 33 to drive the second screw 32 to rotate, the position of the mounting plate 34 can be adjusted left and right, and thus the position of the detection device 37 can be adjusted left and right. This allows for adjustment of the detection device 37 during the detection process, and improves the stability during the adjustment process, further improving the detection accuracy.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
