[0001] The invention belongs to the technical field of coal mine personnel transportation protection, and relates to an anti-impact and shock-absorbing monkey car suitable for rock burst mines. Background Art

[0002] At present, mining monkey cars are frequently used, and with the increase in the mining depth of the mine, the probability of disasters such as rock burst and gas explosion increases. The coal and rock masses thrown out at high speed by rock burst and the high-speed airflow generated by gas explosion seriously threaten the life safety of monkey car passengers underground.

[0003] Existing underground monkey cars cannot effectively protect the lives of monkey car passengers in the event of multiple safety threats such as collisions, falls, injuries from projectiles, and air flow shocks caused by various factors such as natural disasters, mechanical accidents, and improper operation. Therefore, it is urgent to develop a monkey car that can prevent shock and reduce shock in mines with rock burst and high gas mines to protect the lives of monkey car passengers. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-impact and shock-absorbing monkey car suitable for impact ground pressure mines, which solves the problem that the personal safety of passengers in the existing underground monkey car is difficult to be fully guaranteed due to insufficient structural design when the monkey car is hit, falls, hit by thrown objects, air waves and other sudden underground situations.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figure 1 、 Figure 2 、 Figure 3 The structure of the anti-shock and shock-absorbing monkey car of the present invention includes a monkey car vertical rod 6, the top of the monkey car vertical rod 6 is connected to the sling, the bottom end of the monkey car vertical rod 6 is fixedly provided with a downwardly inclined forward pedal 14, and a composite baffle is provided above the pedal 14;

[0020] The structure of the composite baffle is a double-layer protective cover composed of acrylic organic glass 5 and steel mesh 3. The inner surface of the double-layer protective cover is equipped with multiple groups of energy-absorbing springs 1. Each energy-absorbing spring 1 is centripetally connected to the monkey car vertical rod 6 through a rigid support rod 4 ( Figure 2The embodiment comprises three rigid support rods 4 on the top and three rigid support rods 4 on the bottom, totaling six sets of energy-absorbing springs 1); a structural rod 2 is installed on each side of the arc of the double-layer protective cover;

[0021] Opposite to the composite baffle, there are multiple horizontal steel arc tubes 8 (at least three steel arc tubes 8). The multiple steel arc tubes 8 are welded and fixed into an arc frame through vertical connecting rods 13 (at least two connecting rods 13). The arc frame opens and closes as a whole. The hinge point 12 at one end of the arc frame is hinged to the structural rod 2 on one side of the composite baffle. The other end of the arc frame is bonded to the structural rod 2 on the other side of the composite baffle through a magnet 11 (when no one is there) and plugged through a pin 10 (when someone is there); the arc frame is centripetally connected to the composite baffle.

[0022] A seat plate 15 is supported by a support rod 16 at the lower part of the monkey car vertical rod 6, and the seat plate 15 and the support rod 16 are softly connected by a damping shock absorber 9; a backrest 7 is provided in the middle of a steel arc tube 8 in the middle, and the backrest 7 is softly connected to the steel arc tube 8 through another damping shock absorber 9.

[0023] The cross section of the composite baffle is semicircular, the outer layer is a steel mesh 3 for resisting stones and impacts, and the inner layer is an acrylic organic glass 5 for resisting dust and air flow impacts.

[0024] The structural rods 2 designed on both sides of the composite baffle make the composite baffle itself a whole, and also provide rotation and fixed support points for the arc frame composed of multiple steel arc tubes 8.

[0025] The working principle of the device of the present invention is:

[0026] 1) When the monkey car is unloaded, the arc frame is always in a closed state under the action of the magnet 11, and the monkey car itself is relatively safe; if there is a person riding, when the monkey car reaches the side of the passenger, the passenger opens the magnet 11 on the side of the arc frame corresponding to the structural rod 2, sits on the seat plate 15, leans on the backrest 7, steps on the pedal 14, and then closes the arc frame. The middle steel arc tube 8 is naturally attracted to the composite baffle through the magnet 11, and the passenger then uses the pin 10 to connect the middle steel arc tube 8 with the jack on the structural rod 2, so that the arc frame and the composite baffle are firmly closed. The passenger can lean on the backrest 7 during the ride, which increases the riding comfort.

[0027] 2) When the rear of the monkey car collides with the coal wall, the backrest 7 is connected to the steel arc tube 8 through the damping shock absorber 9, and the arc frame can effectively reduce the damage to the passengers caused by the collision impact.

[0028] 3) When the monkey car falls or flies away, the seat plate 15 is connected downward to the monkey car vertical rod 6 through the damping shock absorber 9. The damping shock absorber 9 can absorb most of the vertical stress, and the arc frame greatly reduces the damage caused by the vertical stress.

[0029] 4) The passengers sit on the seat plate 15 facing the composite baffle. First, the acrylic organic glass 5 can withstand the oncoming cold wind and dust. If impact ground pressure occurs underground and coal and rock are thrown out, the wire mesh 3 and the acrylic organic glass 5 can effectively block it together, and the impact generated can be absorbed by the energy-absorbing spring 1. Second, if a gas explosion occurs underground to generate high-speed airflow or a large area of ​​roof collapses to generate a hurricane, the composite baffle can effectively block the high-speed airflow and greatly reduce the damage to the passengers. Third, when the monkey car swings or collides due to mechanical failure, the composite baffle and energy-absorbing spring 1 can also effectively reduce the damage to the passengers caused by the impact.
