The gantry 1 is provided with a detection channel 5, and a tank-type dangerous goods transport vehicle can directly enter the detection channel 5 to facilitate the equipment to perform detection. The gantry 1 is composed of a gantry top plate 11 and a load-bearing floor 15, which form a rectangle. The detection channel 5 is longitudinally arranged inside it, and the load-bearing floor 15 is provided with slots 16 on both side wings relative to the detection channel 5.

In the present application, the load-bearing floor 15 can be provided with multiple sets of anti-skid grooves at intervals in parallel along the extension direction of the detection channel 5. The anti-skid grooves can increase the contact area with the vehicle wheels to prevent the vehicle from slipping and avoid collision between the vehicle and the heavy-duty outriggers 12, which may cause damage to the vehicle and the equipment. A lifting assembly 3 is also provided on the gantry top plate 11. The lifting assembly 3 is installed on the end face of the gantry top plate 11 away from the detection channel 5, which can prevent the vehicle from entering the detection channel 5 and affecting the lifting assembly 3, thereby ensuring the stability of the operation of the lifting assembly 3. The lifting assembly 3 includes multiple sets of synchronous lifting mechanisms 31 and multiple sets of synchronous lifting machines. The structures 31 are connected to each other and arranged at even intervals, and multiple groups of synchronous lifting mechanisms 31 are commonly connected to a group of pressure detection components 4, so that the pressure of each part of the pressure detection component 4 on the overturning protection device is the same, and the ultimate pressure bearing condition of the overturning protection device has been tested more accurately to ensure the test accuracy. The multiple groups of synchronous lifting mechanisms 31 include a driving member, a synchronous screw, a reversing connector, and a lifting part. The driving member is driven and connected to a group of synchronous screws, and the synchronous screws transmit the force of the driving member to the two wings of the gantry top plate 11, and are carried by the reversing connector. Synchronous screws are also provided at the two ends of the reversing connector facing the gantry top plate 11, and the synchronous screws transmit the driving force to the lifting parts arranged at the two ends of the gantry top plate 11.

A thrust sensor 46 is provided at the end of the lifting screw 45 adjacent to the loading plate 41. The joint testing of multiple thrust sensors 46 can ensure the stability of the data.During the test, the monitor connected to the thrust sensor 46 displays the waveform changes during the load and digitizes them, which can effectively improve the test stability and ensure the reliability of the test results.

[0030] Combined with reference Figure 4 In one embodiment of the present application, mounting grooves 42 are opened on both sides of the top of the loading platen 41, and the lifting screws 45 and the thrust sensors 46 are connected to the mounting grooves 42. Multiple groups of lifting screws 45 are wrapped around the top of the loading platen 41. Vertical displacement sensors 43 are provided at the opposite ends of the loading platen 41. The vertical displacement sensors 43 are arranged facing the detection channel 5. An avoidance groove 44 is opened at the end of the loading platen 41 away from the gantry top plate 11, and the avoidance groove 44 is connected to the side edge of the vertical displacement sensor 43.

[0031] In a vehicle top rollover protection device strength test bench of the present application, mounting grooves 42 are provided on both sides of the top of the loading platen 41, and the lifting screw rod 45 and the thrust sensor 46 are connected to the mounting grooves 42, so that the lifting screw rod 45 connected to the lifting assembly 3 can be connected to the bottom of the loading platen 41 as much as possible, so that the connection relationship between the two is more stable, and through the mounting grooves 42, the center of the loading platen 41 can be further downward, and the loading platen 41 is subjected to uniform force at all locations, while ensuring the accuracy of the experimental effect, and the opposite ends of the loading platen 41 are provided with vertical displacement sensors 43, which can be used when the vehicle enters the first detection channel 5. Time, detect the specifications of the vehicle, and automatically adjust the effective travel space required for the test to ensure the test accuracy. At the same time, an avoidance groove 44 is opened at the end of the loading plate 41 away from the gantry top plate 11. Because the tail wing of the tank dangerous goods transport vehicle will be equipped with a ladder, it is convenient for the staff to detect the status of the tank body, and in order to facilitate the staff to use the ladder, the height of the ladder is generally higher than the rollover protection device. When we test the strength of the rollover protection device, the ladder will affect the test. Therefore, an avoidance groove 44 is opened relatively at the side edge of the vertical displacement sensor 43 to avoid the interference of the ladder when the tank body is loaded, so as to ensure the safety and stability of the test.

[0032] Combined with reference Figures 1 to 3 In one embodiment of the present application, the heavy-duty support leg 12 is provided with a lateral displacement sensor 14 facing the detection channel 5 , and the lateral displacement sensor 14 is arranged adjacent to the entrance of the detection channel 5 .

The lateral displacement sensor 14 can detect the real-time width of the vehicle at the first time when the vehicle enters, and automatically guide the lateral offset position of the vehicle when entering, to prevent the gantry 1 from being damaged due to improper operation of the staff. Installing it near the entrance of the detection channel 5 can ensure the first-time detection of the vehicle status, and assist in adjusting the vehicle's driving direction to avoid damage to the equipment.

When the vehicle deviates, the lateral displacement sensor 14 in the deviation direction will emit a red light alarm so that the vehicle state can be adjusted in the first time. The projection of the lateral displacement sensor 14 is within the fixed feet 13 below, and the vehicle is between the fixed feet 13. In this way, the lateral displacement sensor 14 can be prevented from being damaged during the operation of the vehicle, the equipment can be prevented from being damaged during the test, and the stability of the lateral detection can be guaranteed.

[0036] Combined with reference Figure 4 In one embodiment of the present application, a temporary storage portion is provided on the end surface of the load-bearing floor 15 facing the fixed legs 13, the temporary storage portion is located between the fixed legs 13 oppositely arranged on both sides of the detection channel 5, and the temporary storage portion is provided with a beam support leg 17 facing the loading platen 41.

In view of this, it should be avoided to apply a loading force higher than this limit value to each tire. In terms of design, the test bench adopts a plurality of beam support legs 17, which are respectively supported at the bottom of the longitudinal beam and the cross beam of the vehicle between the iron floor and the frame to bear the loading force applied to each tire, so as to avoid the tire being unable to withstand the pressure and being damaged during the test, resulting in errors in the test results.

[0038] Combined with reference Figure 4 In one embodiment of the present application, a plurality of beam support feet 17 are provided, and the plurality of beam support feet 17 are evenly spaced apart. The supporting ends of the beam support feet 17 are connected to support plates 18 , and the support plates 18 are arc-shaped.
