In addition to further strengthening the safety of the climbing vehicle control system, if there is no appropriate protection measure, it is easy to cause relatively large damage to the climbing vehicle body during a collision, and it is also easy to pose a safety threat to the passengers. Summary of the Utility Model
[0003] In order to solve the above defects, the utility model provides an anti-collision safety device for climbing vehicles, which solves the safety problem of relatively large damage to the vehicle body during the collision of climbing vehicles.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

The anti-collision beam includes a base beam and a D-shaped collision beam. The anti-collision component includes an anti-collision needle, an elastic member, a connecting shaft, a blocking block, a collision block, and a fixed shaft sleeve fixed on the vehicle frame. The anti-collision needle, the elastic member, the connecting shaft, and the blocking block are arranged inside the fixed sleeve shaft. The anti-collision needle includes a head, a middle part, and a tail. The tail and the collision block are respectively fixedly connected to both ends of the connecting shaft. The elastic member is sleeved on the surface of the connecting shaft and respectively abuts against the tail and the blocking block. The connecting shaft passes through the blocking block and is fixedly connected to the collision block.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] As Figures 1 to 3As shown in the figure, an anti-collision safety device for a climbing vehicle includes an anti-collision beam, an anti-collision component, and a proximity switch fixed on the vehicle frame and used in cooperation with the anti-collision component. The anti-collision beam includes a base beam and a D-shaped collision beam. The anti-collision component includes an anti-collision needle, an elastic member, a connecting shaft, a blocking block, a collision block, and a fixed sleeve shaft fixed on the vehicle frame. The anti-collision needle, the elastic member, the connecting shaft, and the blocking block are arranged inside the fixed sleeve shaft. The anti-collision needle includes a head, a middle part, and a tail. The tail and the collision block are respectively fixedly connected to both ends of the connecting shaft. The elastic member is sleeved on the surface of the connecting shaft and abuts against the tail and the blocking block respectively. The connecting shaft passes through the blocking block and is fixedly connected to the collision block. The head passes through the base beam and the collision beam and abuts against the inner wall of the collision beam. A chute is arranged on the outer wall of the head. A through hole is opened at a corresponding position on the base beam, and a fixing bolt is arranged to extend into the chute through the through hole.
[0023] With the above technical solution, by setting the cooperation of the anti-collision beam, the anti-collision component, and the proximity switch, when the climbing vehicle collides, the anti-collision beam is first subjected to the impact force. The anti-collision needle abutting against the inner wall of the anti-collision beam is pushed by the impact force and displaces inside the fixed shaft sleeve. The collision block connected to the anti-collision needle through the connecting shaft displaces along the same direction. When the collision block touches the proximity switch, the proximity switch sends a collision signal to the climbing vehicle control system. The climbing vehicle control system sends an emergency braking signal, and the climbing vehicle stops braking, avoiding greater damage caused by the continuous collision of the climbing vehicle; by setting the elastic member, the reset function of the spring is used to reset the anti-collision needle; by setting the chute and the fixing bolt, the displacement distance of the anti-collision needle can be limited, avoiding the damage caused by the impact of the collision block on the proximity switch and ensuring the safety of the proximity switch.
[0024] As Figure 1 and Figure 2 shown, the base beam is an arc-shaped triangular structure, with a double T-shaped cross-section and several holes on the surface.
[0025] With the above technical solution, by setting the base beam to be arc-shaped, the impact on the anti-collision needle can be reduced by the deformation of the arc, playing a buffering role. At the same time, several holes are set to form a complete energy absorption structure to absorb the energy generated during the collision, thereby protecting the main structure of the vehicle.
[0026] As Figure 1 and Figure 2 shown, the collision beam is an arc-shaped tube, with the same radian as the base beam and a D-shaped cross-section.
[0027] With the above technical solution, by setting the collision beam as a D-shaped arc-shaped tube, the aim is to provide additional protection. Through its specific shape and structure, the impact force can be effectively absorbed and dispersed, thereby protecting the structure and personnel safety.
[0028] As Figure 1 and Figure 2 shown, the foundation beam and the collision beam are fixedly connected by bolts.
[0029] Adopting the above technical solution, by fixedly connecting the foundation beam and the collision beam with bolts, the stability and firmness of the structure are increased.
[0030] As Figure 2 shown, the fixing bolt is threadedly connected with the through hole.
[0031] Adopting the above technical solution, by setting the fixing bolt to be threadedly connected with the through hole, the depth of the fixing bolt extending into the chute can be adjusted.
[0032] As Figure 2 and Figure 3 shown, the diameters of the head and the tail are larger than the diameter of the middle part.
[0033] Adopting the above technical solution, by setting the diameters of the head and the tail to be larger than the diameter of the middle part, it helps the anti-collision pin move smoothly inside the fixed bushing.
[0034] As Figure 2 and Figure 3 shown, the elastic member is a cylindrical helical spring.
[0035] Adopting the above technical solution, by setting the elastic member as a cylindrical helical spring, the anti-collision pin can be reset by using the spring's reset, and at the same time, the impact force of the anti-collision pin on the proximity switch is reduced to protect the proximity switch.
[0036] Working principle
[0037] When the climbing vehicle collides, the anti-collision beam is first subjected to the impact force. The anti-collision pin in contact with the inner wall of the anti-collision beam is pushed by the impact force and displaces inside the fixed bushing. The collision block connected to the anti-collision pin by the connecting shaft displaces in the same direction. When the collision block touches the proximity switch, the proximity switch sends a collision signal to the climbing vehicle control system, and the climbing vehicle control system sends an emergency braking signal, and the climbing vehicle stops, avoiding greater damage caused by continued collision of the climbing vehicle.
[0038] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is less than that of the second feature.
