Description

Technical Field

[0001] This utility model relates to the technical field of crane wind resistance testing, and in particular to a multi-parameter simulation test device for emergency braking of cranes in wind resistance. Background Technology

[0002] The multi-parameter simulation experimental device for wind-resistant emergency braking of cranes is a device used to study various parameters and performance of cranes during wind-resistant emergency braking. It can simulate the wind-resistant braking process of cranes under various working conditions, helping researchers to understand the reasons for the failure of cranes' wind-resistant and anti-slip mechanisms, such as insufficient friction coefficient of wind-resistant braking devices, the influence of wind uplift force, the effect of the load on the crane, and the influence of foreign objects between the track and wheels.

[0003] Current multi-parameter simulation experimental devices, when pushing cranes to simulate wind force, cannot achieve stable and uniform pushing of the crane body by hydraulic cylinders due to the different sizes of the cranes. This results in different thrusts on both sides of the crane, leading to large data errors during crane experiments, which reduces the working effect of the multi-parameter simulation experimental device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-parameter simulation experimental device for emergency braking of cranes against wind.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-parameter simulation experimental device for wind-resistant emergency braking of a crane includes a crane body, a slider, a slide rail, a first threaded hole, a fixed seat, a first bolt, a vertical plate, a reinforcing rib, a second threaded hole, a bent plate, a second bolt, a hydraulic cylinder, and a square plate. The upper surfaces of the two vertical plates are respectively provided with multiple second threaded holes, wherein the two second threaded holes are respectively threadedly connected to the corresponding second bolts, the two second bolts respectively movably pass through the corresponding bent plates, and the surfaces of the two bent plates respectively contact the corresponding vertical plates.

[0007] Preferably, the upper surface of the plurality of slide rails is provided with a plurality of first threaded holes, two of the first threaded holes are threadedly connected to the corresponding first bolts, each of the first bolts movably passes through the corresponding fixed seat, and each of the fixed seats is slidably connected to the corresponding slide rail.

[0008] Preferably, the outer walls of the two curved plates are fixedly connected to the ends of the corresponding hydraulic cylinders, and the output ends of the two hydraulic cylinders are fixedly connected to the corresponding square plates.

[0009] Preferably, both of the square plates are in contact with the crane body.

[0010] Preferably, the upper ends of both of the fixing seats are fixedly connected to the corresponding vertical plates.

[0011] Preferably, the outer wall of each vertical plate is fixedly connected to four reinforcing ribs, the lower end of the crane body is fixedly connected to two sliders, and the two sliders are slidably connected to corresponding slide rails.

[0012] Preferably, the upper surface of each of the fixing seats is fixedly connected to four reinforcing ribs.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using the vertical plate, second threaded hole, second bolt, and bent plate, when the position of the hydraulic cylinder needs to be moved, the operator first removes the second bolt from the second threaded hole, then slides the bent plate along the vertical plate. The bent plate moves the hydraulic cylinder, which in turn moves the square plate. After the square plate moves to the appropriate position, the operator screws the second bolt into the second threaded hole to fix the position of the bent plate. In this way, the position of the hydraulic cylinder can be adjusted, so that the square plate can better apply pressure evenly to the crane body, avoiding large errors in the data of the crane body during the simulation experiment, thereby improving the working effect of the multi-parameter simulation experiment device.

[0015] 2. Through the set first threaded hole, first bolt, second threaded hole, second bolt, vertical plate, slide rail and fixed seat, when the first bolt is removed from the first threaded hole, the fixed seat can be disassembled on the slide rail. When the second bolt is removed from the second threaded hole, the bent plate can be disassembled from the vertical plate. This allows the multi-parameter simulation experimental device to be disassembled. When the operator needs to maintain the experimental device, it is very convenient to replace the equipment that needs maintenance, which also improves the working effect of the multi-parameter simulation experimental device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A multi-parameter simulation experimental device for wind-resistant emergency braking of a crane includes a crane body 1, a slider 2, a slide rail 3, a first threaded hole 4, a fixed seat 5, a first bolt 6, a vertical plate 7, a reinforcing rib 8, a second threaded hole 9, a bent plate 10, a second bolt 11, a hydraulic cylinder 12, and a square plate 13. The upper surfaces of the two vertical plates 7 are respectively provided with multiple second threaded holes 9, wherein the two second threaded holes 9 are respectively threadedly connected to the corresponding second bolts 11. The second bolts 11 are tightened inside the second threaded holes 9. The two second bolts 11 respectively move through the corresponding bent plates 10, and the second bolts 11 fix the position of the bent plates 10. The surfaces of the two bent plates 10 are in contact with the corresponding vertical plates 7. When the position of the hydraulic cylinder 12 needs to be moved, the operator first removes the second bolt 11 from the second threaded hole 9, and then slides the bent plate 10 along the vertical plate 7. The bent plate 10 drives the hydraulic cylinder 12 to move, and the hydraulic cylinder 12 drives the square plate 13 to move. After the square plate 13 moves to the appropriate position, the operator screws the second bolt 11 into the second threaded hole 9 to fix the position of the bent plate 10. In this way, the position of the hydraulic cylinder 12 can be adjusted, so that the square plate 13 can better apply pressure evenly to the crane body 1, avoid large errors in the data of the crane body 1 during the simulation experiment, and thus improve the working effect of the multi-parameter simulation experiment device.

[0024] In this embodiment, multiple first threaded holes 4 are provided on the upper surface of multiple slide rails 3. Two first threaded holes 4 are threadedly connected to corresponding first bolts 6. The first bolts 6 are inserted into the first threaded holes 4. Each first bolt 6 movably passes through a corresponding fixed seat 5. Each fixed seat 5 is slidably connected to a corresponding slide rail 3. The fixed seat 5 slides on the slide rail 3. The outer walls of two curved plates 10 are fixedly connected to the ends of corresponding hydraulic cylinders 12. The curved plates 10 drive the hydraulic cylinders 12 to move. The model of the hydraulic cylinders 12 is selected according to actual needs, and only those that meet the working requirements are selected. The output ends of the two hydraulic cylinders 12 are fixedly connected to corresponding square plates 13. The hydraulic cylinders 12 drive the square plates 13 to move. All plates 13 are in contact with the crane body 1. The square plates 13 are pressed against the crane body 1. Rubber pads are adhered at the contact points between the square plates 13 and the crane body 1 to prevent damage to the surface of the crane body 1. The upper ends of the two fixed seats 5 are fixedly connected to the corresponding vertical plates 7. The fixed seats 5 drive the vertical plates 7 to move. The outer wall of each vertical plate 7 is fixedly connected to four reinforcing ribs 8. The reinforcing ribs 8 reinforce the vertical plates 7. The lower end of the crane body 1 is fixedly connected to two sliders 2. The sliders 2 drive the crane body 1 to move. The two sliders 2 are slidably connected to the corresponding slide rails 3. The sliders 2 slide on the slide rails 3. The upper surface of each fixed seat 5 is fixedly connected to four reinforcing ribs 8.

[0025] The working principle of this embodiment is as follows: In use, the operator first inserts the fixed seat 5 into the slide rail 3, and then slides it along the slide rail 3. The fixed seat 5 moves to a suitable position so that the hydraulic cylinder 12 can drive the square plate 13 to press against the crane body 1. The operator then stops moving the fixed seat 5 and tightens the first bolt 6 into the first threaded hole 4 to fix the slide rail 3 and the fixed seat 5. Then the operator removes the second bolt 11 from the second threaded hole 9. Then the operator slides the curved plate 10 along the vertical plate 7. The curved plate 10 drives the hydraulic cylinder 12 to move, and the hydraulic cylinder 12 drives the square plate 13 to move. After the square plate 13 moves to a suitable position, the operator tightens the second bolt 11 into the second threaded hole 9 to fix the position of the curved plate 10. Then the operator connects the external power supply of the hydraulic cylinder 12 and starts the hydraulic cylinder 12. The hydraulic cylinder 12 drives the square plate 13 to press against the crane body 1, and applies pressure to the crane body 1 through the square plate 13, so that the crane body 1 is subjected to wind force. The operator collects the experimental data and completes the multi-parameter simulation experiment through multiple tests.
