The front intercepting device includes a left buffer energy absorber 1, a left driver 2, a left intercepting door 3, a left self-locking member 4, a right buffer energy absorber 5, a right driver 6, a right intercepting door 7, a right self-locking member 8, a door suction 9 and a control box; the left buffer energy absorber 1 and the left intercepting door 3 are installed on the left side wall of the lane from left to right, the left buffer energy absorber 1 is connected to the left intercepting door 3 by a wire rope, and the left upper side of the left intercepting door 3 The left end is connected to the left side wall of the lane through the left driver 2, the right side of the left intercepting door 3 is connected to the left self-locking part 4, and the left intercepting door 3 is attached to the left side wall of the lane through the door suction 9; the right buffer energy absorber 5 and the right intercepting door 7 are installed on the right side wall of the lane from left to right, the right buffer energy absorber 5 is connected to the right intercepting door 7 through a wire rope, the left upper end of the right intercepting door 7 is connected to the right side wall of the lane through the right driver 6, the right side of the right intercepting door 7 is connected to the right self-locking part 8, the left self-locking part 4 and the right self-locking part 8 are connected in combination, the right intercepting door 7 is attached to the right side wall of the lane through the door suction 9, and the control box is electrically connected to the left driver 2 and the right driver 6 respectively.

[0043] The hookless flexible front intercepting device for rubber-tyred vehicles provided by the present invention has the following conditions: in normal driving state, the left intercepting door 3 and the right intercepting door 7 are both attached to the side wall of the lane through the door suction 9; when the vehicle stalls, the speed measuring radar installed in the lane detects overspeeding and sends a control signal to the control box, and the control box drives the left driver 2 and the right driver 6 to open the left intercepting door 3 and the right intercepting door 7 at the same time; when the left intercepting door 3 is opened to the position, the left driver 2 supports the left intercepting door 3 to fix the left intercepting door 3, and the right intercepting door 7 is pushed by the right driver 6 to hit the left intercepting door 3 until the left self-locking member 4 and the right self-locking member 8 collide and lock, thereby connecting the left intercepting door 3 and the right intercepting door 7 into a whole; after the left intercepting door 3 and the right intercepting door 7 are connected into a whole intercepting door, under the impact of the stalled rubber-tyred vehicle It will be deformed into a C shape to wrap around the front of the vehicle, and the front of the vehicle will move with the overall interception door, and the overall interception door will pull the steel wire rope on the buffer energy absorber (left buffer energy absorber 1 and right buffer energy absorber 5) to move, and the movement of the steel wire rope will drive the buffer energy absorber to brake and slow down; there is no need to install a large hook or other equipment on the vehicle, and the deformation and damage to the cab during interception by the interception net can be avoided, thereby effectively intercepting the rubber-wheeled vehicle, and because the left interception door 3, the right interception door 7 and the left buffer energy absorber 1 and the right buffer energy absorber 5 of the device are all buffered, so when the interception door intercepts the rubber-wheeled vehicle, the impact on the cab is not large, and the generated interception acceleration is within the normal human tolerance range of 0.5-2.5g, so the driver will not be injured during interception.

[0044] Furthermore, the adsorption force of the door suction 9 at the left intercepting door 3 is 15-30% greater than the component of the gravity of the left intercepting door 3 along the slope direction, and the adsorption force of the door suction 9 at the right intercepting door 7 is 15-30% greater than the component of the gravity of the right intercepting door 7 along the slope direction; it is ensured that the left intercepting door 3 and the right intercepting door 7 are not opened when the vehicle is driving; the door suction 9 is an existing device, and a suitable door suction is selected according to needs in actual use, which is not described in detail here.

[0045] Embodiment 2:

[0046] On the basis of Example 1, further, Figure 3-6 As shown, the left intercepting door 3 and the right intercepting door 7 both include a door shaft 3-1, a door frame 3-2 and a plurality of energy absorbing cylinders 3-3, the left side of the door frame 3-2 is connected to the door shaft 3-1, the upper end of the door shaft 3-1 of the left intercepting door 3 is connected to the left driver 2, the upper end of the door shaft 3-1 of the right intercepting door 7 is connected to the right driver 6, the left buffer energy absorber 1 is connected to the door shaft 3-1 of the left intercepting door 3 via a steel wire rope, the right buffer energy absorber 5 is connected to the door shaft 3-1 of the right intercepting door 7 via a steel wire rope, and a plurality of energy absorbing cylinders 3-3 are sleeved on the door frame 3-2.

[0047] The structure is simple, and when an out-of-control vehicle hits the integral intercepting door, the energy-absorbing cylinder 3-3 on the door frame 3-2 will adhere to and wrap the front of the vehicle (the wrapping position is based on the height position of the beam of the rubber-wheeled vehicle as the height center position, that is, the main force position of the front of the vehicle is the beam corresponding to the front bumper), and the energy-absorbing cylinder 3-3 provides buffering protection for the cab.

[0048] Furthermore, the shape of the energy absorbing cylinder 3-3 is cylindrical or spherical, and the door frame 3-2 is mounted on the central axis of the cylinder or spherical shape, which has a simple structure and good buffering performance.

[0049] Furthermore, the energy absorbing cylinder 3-3 is made of nano energy absorbing material. The nano energy absorbing material has excellent energy absorption performance. When the vehicle hits the interception door, it can greatly migrate and slow down the shock wave, greatly reducing the damage caused by the external force impact. The nano energy absorbing material also has strong stability, is not easy to deform, and can be reused, avoiding the defect that the traditional energy absorbing material can only be used once.

[0050] Furthermore, it also includes a door shaft seat 10, through which the lower end of the door shaft 3-1 of the left intercepting door 3 is connected to the left side wall of the lane, and the lower end of the door shaft 3-1 of the right intercepting door 7 is connected to the right side wall of the lane. During normal driving, the door shaft seat 10 facilitates the installation of the left intercepting door 3 and the right intercepting door 7 on the side wall of the lane. When the integral intercepting door is hit, the integral intercepting door can be detached from the door shaft seat 10, which is simple to connect and avoids damage to the intercepting door (left intercepting door and right intercepting door) and the side wall of the lane during use.

[0051] Further, such as Figure 18-20 As shown, the door axis seat 10 includes a first connecting plate 10-1, a second connecting plate 10-2, a third connecting plate 10-3 and a door axis connecting shaft 10-4. The first connecting plate 10-1 and the second connecting plate 10-2 are both vertically arranged. The left end of the first connecting plate 10-1 is vertically connected to the second connecting plate 10-2, and the right side of the second connecting plate 10-2 is horizontally and vertically connected to the third connecting plate 10-3. The third connecting plate 10-3 is vertically connected to the door axis connecting shaft 10-4, and the door axis connecting shaft 10-4 is connected to the lower end of the door axis 3-1; the door axis 3-1 rotates inside the door axis connecting shaft 10-4 to facilitate the movement (opening or closing) of the intercepting door. When the overall intercepting door is hit, the intercepting door drives the door axis connecting shaft 10-4 to detach from the third connecting plate 10-3 through the door axis 3-1, so as to facilitate the detachment of the intercepting door from the door axis seat.

[0052] Further, such as Figure 7-8As shown, the door shaft 3-1 includes a door shaft rod 3-11 and a lever 3-12, the door shaft rod 3-11 is vertically arranged, and the upper end of the door shaft rod 3-11 is horizontally connected to the lever 3-12. The door shaft rod 3-11 has a simple structure, which is convenient for the interception door to connect the driver (left driver or right driver) and the door shaft seat, and the lever 3-12 has a simple structure and when used for interception, it can firmly support the driver, so that the left interception door and the right interception door can be self-lockingly connected as a whole.

The chamber 2-2 is excavated on the side wall of the tunnel. One end of the cylinder body 2-1 is connected to the chamber 2-2 through the mounting base 2-3. The other end of the cylinder body 2-1 is connected to one end of the shift fork 2-12 through the push rod 2-11. The other end of the shift fork 2-12 is connected to the lever 3-12. The lever 3-12 and the shift fork 2-12 are matched and connected to hold the interception door fixed, with a simple structure and convenient connection. The mounting base 2-3 facilitates the fixing of the cylinder body 2-1 in the chamber 2-2 without affecting the matching connection of the lever 3-12 and the shift fork 2-12. At the same time, the lever 3-12 facilitates the separation of the shift fork 2-12 and the lever 3-12 when the interception door is intercepted. The entire left driver 2 and right driver 6 will not be moved with the interception door. And the interception door and the lane sidewall will not be damaged.

[0055] Furthermore, a notch 2-13 is provided at the right end of the shift fork 2-12, and the shift rod 3-12 is clamped in the notch 2-13. The notch 2-13 has a simple structure and is convenient for the stable clamping of the shift rod 3-12.

[0056] Embodiment 4:

[0057] On the basis of Example 3, further, Figure 14-15 As shown, the left self-locking member 4 includes a second angle steel 4-1, a lock tongue plate 4-2, a lock tongue baffle 4-3, a reset torsion spring 4-4, an upper angle adjustment seat 4-5 and a lower angle adjustment seat 4-6. The left side of the second angle steel 4-1 is connected to the left intercepting door 3, and the right side of the second angle steel 4-1 is horizontally connected to the upper angle adjustment seat 4-5 and the lower angle adjustment seat 4-6 from top to bottom. The lower right part of the upper angle adjustment seat 4-5 is connected to the lock tongue baffle 4-3, and the upper right part of the lower angle adjustment seat 4-6 is connected to the lower inner side of the lock tongue plate 4-2 through the reset torsion spring 4-4. The upper outer side of the lock tongue plate 4-2 contacts the lower inner side of the lock tongue baffle 4-3.

[0058] Furthermore, the upper angle adjustment seat 4-5 includes an upper plate 4-8 and an upper adjustment knob 4-7, and the lower angle adjustment seat 4-6 includes a lower plate 4-9 and a lower adjustment knob 4-10; the second angle steel 4-1 is horizontally spaced from top to bottom on the right side to connect the upper plate 4-8 and the lower plate 4-9, the upper plate 4-8 is connected to the lock tongue baffle 4-3 through the upper adjustment knob 4-7, and the lower plate 4-9 is connected to the reset torsion spring 4-4 ​​through the lower adjustment knob 4-10; the angle of the lock tongue baffle 4-3 can be adjusted by rotating the upper adjustment knob 4-7, and the angle of the reset torsion spring 4-4 ​​can be adjusted by rotating the lower adjustment knob 4-10, with a simple structure and convenient operation.

[0059] like Figure 12-13 As shown, the right self-locking member 8 includes a buckle 8-1 and a first angle steel 8-2. The buckle 8-1 is connected to the right intercepting door 7 through the first angle steel 8-2. When the left self-locking member 4 and the right self-locking member 8 are locked and connected, the buckle 8-1 is sleeved on the lock tongue plate 4-2.

[0060] The first angle steel 8-2 and the second angle steel 4-1 have a simple structure and a stable connection. When intercepting and self-locking, the buckle 8-1 collides with the lock tongue plate 4-2 in the direction of the second angle steel 4-1, thereby compressing the reset torsion spring 4-4, causing the lock tongue plate 4-2 to rotate. When it rotates into place, the reset torsion spring 4-4 ​​relies on the spring force to automatically reset the lock tongue plate 4-2 to a vertical position, and the lock tongue plate 4-2 is just inserted into the buckle 8-1, and self-locking is completed. Due to the limit of the lock tongue baffle 4-3, the overall interception door is prevented from being opened during interception, thereby ensuring the interception effect.

[0061] Furthermore, the number of the left self-locking parts 4 and the right self-locking parts 8 are both multiple; the multiple left self-locking parts 4 are connected to the left intercepting door 3 at equal intervals from top to bottom, and the multiple right self-locking parts 8 are connected to the right intercepting door 7 at equal intervals from top to bottom, and the left self-locking parts 4 and the right self-locking parts 8 have the same height; the number of self-locking parts is selected according to actual conditions to ensure the stability of the connection; the left self-locking parts 4 and the right self-locking parts 8 have the same height to ensure that the left self-locking part 4 can lock the right self-locking part 8.

[0067] After the left interception door 3 and the left interception door 3 are connected to form an integral interception door, they will be deformed into a C shape and wrap around the front of the vehicle under the impact of the stalled rubber-wheeled vehicle. The front of the vehicle carries the integral interception door to move, and the integral interception door will pull the wire rope on the buffer energy absorber (left buffer energy absorber 1 and right buffer energy absorber 5) (one end of the wire rope is wrapped and connected to the outside of the drum 1-1, and the other end of the wire rope is fixedly connected to the door shaft 3-1); the movement of the integral interception door drives the door shaft 3-1 to pull one end of the wire rope to move, and then the other end of the wire rope pulls the drum 1-1 to rotate, so that the wire rope wrapped around the drum 1-1 is unfolded, and the drum 1-1 rotates, driving the drum shaft 1-2 to rotate; during the rotation of the drum shaft 1-2, the right end of the buffer wire rope 1-3 is wrapped around the drum shaft 1-2, and the left end of the buffer wire rope 1-3 pulls the rotating sleeve 1-6 to rotate, and the rotating sleeve 1-6 rotates When the screw rod 1-7 moves horizontally to the left by the thread, the screw rod 1-7 moves to the left by driving the brake pad tensioning member 1-8 to move to the left, so that the brake pad 1-9 gradually tightens the brake drum 1-10, and the friction resistance of the buffer energy absorber 1 gradually increases, so that the initial buffering force of stopping the vehicle gradually increases from small to large; when the braking force reaches the design requirement and can give the rubber-wheeled vehicle a negative acceleration of 0.5-2.5G, the buffer wire rope 1-3 will be broken, and the brake pad 1-9 will not further tighten the brake drum 1-10, so that the friction force of the energy absorber is controlled within the range of the design force value, and the rubber-wheeled vehicle will not cause harm to the personnel on the vehicle due to excessive braking acceleration; under the continuous action of the friction force of the buffer energy absorber, the rubber-wheeled vehicle will stop at a distance of no more than 50 meters, thereby protecting the safety of the personnel underground and in the vehicle.
