Description

Technical Field

[0001] The utility model relates to the technical field of urban construction, in particular to a device for preventing a battery vehicle of equipment behind a shield machine from slipping. Background Art

[0002] For shield construction, urban integrated pipe corridors and subways are significantly different. Since urban integrated pipe corridors do not run subways, but only lay various urban pipelines, the tunnel slope may be large. Due to the current power limitation of electric vehicles, the traditional method is that the electric vehicle pulls the slag bucket in the tunnel. When encountering a large slope and the electric vehicle is loaded, the braking effect of the electric vehicle is not good, and there is a risk of slipping. After experimental research, we have developed a tool specifically for electric vehicle anti-slipping under large-slope shield tunnel conditions. It is operated by the electric vehicle driver, which greatly increases the friction between the electric vehicle and the track and solves the problem of electric vehicle slipping in the tunnel.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 As shown, the utility model provides a technical solution: a device for preventing a battery vehicle equipped at the rear of a shield machine from slipping, which is arranged on the shield machine and includes: a sandbox structure and a control structure, the sandbox structure is arranged on the shield machine to prevent the electric vehicle from slipping, and the control structure is arranged on the sandbox structure to control the sandbox structure.

[0018] There are at least two sandbox structures for expanding the scope of operation. The sandbox structure is used to release the anti-skid material 3 downward. The sandbox structure includes a storage box 2 for storing the anti-skid material 3 arranged on the shield machine. The storage box 2 is used to store the anti-skid material 3. The dimensions of the storage box 2 are 250 mm in length, width and height. The bottom of the storage box 2 is funnel-shaped. The inclination angle of the funnel at the bottom of the storage box 2 is twenty-eight degrees, which is used to facilitate the discharge of the anti-skid material 3 outward through the discharge pipe 5. The material of the anti-skid material 3 is fine sand, and there is a discharge pipe 5 arranged on the storage box 2. The discharge pipe 5 is arranged at the bottom of the pneumatic valve 4, and the pneumatic valve 4 can be used to control the discharge pipe 5 to discharge the anti-skid material 3. The sandbox structure releases the anti-skid material 3 downward. The number of storage boxes 2 and the discharge pipe 5 is two, thereby expanding the area for releasing the anti-skid material 3 downward to increase the anti-skid effect on the electric vehicle, thereby alleviating the situation of the electric vehicle slipping.

[0019] The control structure includes a pneumatic valve 4 arranged on the sandbox structure. The length and width of the pneumatic valve 4 are 50mm*60mm. The pneumatic valve 4 is used to control the discharge of the discharge pipe 5, and the air pipe 1 is used to control the pneumatic valve 4. The number of pneumatic valves 4 is the same as the number of storage boxes 2, which is two. The two pneumatic valves 4 are controlled by the air pipe 1. The control structure is used to control whether the sandbox structure is open. The number of pneumatic valves 4 is the same as that of the sandbox structure, and is used to separately control the sandbox structure. A single pneumatic valve 4 is used to control a single sandbox structure.

[0020] According to the above, in this embodiment, the two pneumatic valves 4 are closed through the air pipe 1, and then the anti-skid material 3 is loaded on the storage box 2, and the battery vehicle is started to open the pneumatic valve 4 to test the effect of spraying the anti-skid material 3.
