Description

Technical Field

[0001] The invention relates to the technical field of mine car cab structures, and in particular to a high-safety anti-torsion structure of a mine car cab. Background Art

[0002] The cab of a mine car is the main working area for the driver of a mine car (such as a mining transporter) to operate and control the vehicle. Mine cars are commonly found in mines, quarries, open-pit mining areas and other environments, and are used to transport heavy objects such as ore, coal, and building materials. Since mine cars operate in harsh terrain and working environments, the design of the cab must take into account comfort, safety, and functionality to ensure that the driver can maintain a stable working state during long-term, high-load operations and cope with sudden terrain changes and potential safety risks.

[0003] The high-safety anti-torsion structure of the mine car cab is to ensure the safety of the driver in the harsh environment of the mining area, especially when the mine car passes through uneven and steep terrain or rolls over, which can effectively protect the driver's life. This design usually includes enhancing the torsion resistance, impact resistance and overall strength of the cab, so as to ensure that the cab can withstand various stresses and impacts of the mine car in complex terrain.

[0004] Due to the poor quality of the road surface in the mining area, the risk of dumping when the mine car is driving on uneven or poor quality roads is indeed a serious safety hazard, especially during transportation. When the mine car tilts or dumps, it will pose a threat to the driver's safety, and may also cause damage to the mine car and loss of cargo. Most mine car cab designs do not take into account the protection of the driver when the mine car tilts. If the mine car tilts or rolls over, the driver may not be effectively protected. Most existing cabs use a simple steel frame structure, which can prevent collisions to a certain extent, but may not provide sufficient support and cushioning if the mine car tilts or rolls over significantly.

[0005] In summary, the prior art lacks the technology for automatically preventing the mine car cab from overturning. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a high-safety anti-torsion structure for a mine car cab.

[0009] Preferably, the retracting and releasing mechanism includes a worm A having two worm teeth with opposite rotation directions, the worm A being rotatably connected to the reinforcing column, a transmission sleeve being fixedly connected to the top of the worm A, and the inner wall of the transmission sleeve being slidably matched with the outer wall of the transmission shaft.

[0010] Preferably, two worm wheels A are meshingly provided on one side of the worm gear A, and the worm wheel A is rotatably connected to the reinforcing column through a pin shaft. A retractable rod group is fixedly connected to the worm wheel A, and the other end of the retractable rod group is rotatably connected to the moving frame. An arc-shaped rack is fixedly connected to one end of the retractable rod group close to the moving frame.

[0011] Preferably, the anti-dumping mechanism includes a support column, which is slidably matched with the inner wall of the movable frame, the bottom end of the support column is connected and fixedly provided with a fixed support seat, and a movable support seat is rotatably connected to the fixed support seat, and a serrated plate is connected to one side of the fixed support seat and the movable support seat.

[0012] Preferably, a universal joint A is rotatably connected to the inner wall of one side of the fixed support seat, one end of the universal joint A is fixedly connected to the movable support seat, the other end of the universal joint A is fixedly connected to a worm gear B, one side of the worm gear B is meshingly equipped with a worm B, the worm B is rotatably connected to the inner wall of the fixed support seat, and one end of the worm gear B is fixedly connected to an adjusting wheel.

[0013] Preferably, a fixed rack is fixedly connected to the bottom end of the movable frame, and the fixed rack is meshed with the adjusting wheel for transmission.

[0014] Preferably, the transmission mechanism includes a universal joint B, both ends of which are rotatably connected to the inner wall of the movable frame, one end of the universal joint B is connected and fixed with a threaded rod, the threaded rod is threadedly connected to a support column, the other end of the universal joint B is connected and fixed with a rotating shaft, a transmission wheel is connected and fixed on the rotating shaft, and the transmission wheel is meshed with an arc-shaped rack for transmission.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During the use of the mine car, by setting up an anti-dumping mechanism, when the mine car tilts too much, the support column can be used to drive the fixed support seat to move down to support the mine car, which can effectively avoid the danger of the mine car tipping over or tilting too much, ensure the life safety and operation safety of the miners, effectively improve the stability of the mine car in a complex operating environment, reduce the risk of accidents, and ensure the safety and efficiency of mining operations;

[0018] 2. By setting up a movable support seat, the support area can be increased, the gravity of the vehicle can be effectively dispersed, the pressure caused by single-point support can be reduced, and the vehicle overturning caused by overload of the support point can be avoided. The large-area support helps to reduce the ground pressure of the support point, especially on soft or uneven ground, which can prevent the support seat from sinking into the soil or gravel. By increasing the support area, the roll tolerance of the mine car can be improved, and the mine car can be prevented from overturning on steep slopes or uneven roads, reducing accidents caused by overturning. By setting up an adjustment mechanism, the mobile frame can be driven to be retracted and released. When the mine car is driving normally or stopped, the support frame can be retracted to avoid taking up too much space and affecting the transportation capacity of the mine car. When support is needed, the support frame will automatically unfold without taking up extra space;

[0019] 3. By setting reinforcing ribs on the reinforcing columns, the torsional strength of the cab can be improved, which can significantly enhance the structural strength of the cab, reduce the distortion or deformation caused by external forces, and ensure the safety of the staff in the cab. By setting shock-absorbing springs and protective covers, shock-absorbing protection for the motor can be achieved to ensure its service life under the harsh conditions of the mining area.
