The rotation of the transmission rod 34 drives the sliding seat assembly 32 to move rightward along the first slide bar 33 and the second slide bar 35. At this time, the lower end of the support plate 15 connected to the sliding seat 68 by the fourth shaft 23 moves rightward and the height is reduced, and the height of the right end of the first flap 13 is also reduced;

[0029] S3, the brake motor 37 continues to reverse until the sliding seat 68 of the sliding seat assembly 32 triggers the second switch 30, so that the second switch 30 is disconnected, the coil KM2 loses power, the normally open contact KM2 of the contactor is disconnected, and the brake motor 37 stops rotating. At this time, the upper surfaces of the first flap 13 and the second flap 18 are in a horizontal state, and the upper surfaces of the first dustproof plate 2 and the second dustproof plate 8 are flush with the upper surface of the car bottom, and the vehicle is in a state of passage;

[0030] S4, switch SW is closed, coil KM is energized, contactor normally open contact KMA is closed, contactor normally closed contact KMB is disconnected, sound and light control switch works, L1 circuit of brake motor 37 is closed, and L2 circuit is disconnected;

[0031] S5, the first switch 28 is closed, the coil KM1 is energized, the normally open contact KM1 of the contactor is closed, the L1 circuit of the brake motor 37 is closed, the brake motor 37 rotates clockwise, driving the transmission rod 34 to rotate, and the rotation of the transmission rod 34 drives the sliding seat assembly 32 to move leftward along the first slide bar 33 and the second slide bar 35. At this time, the lower end of the support plate 15 connected to the sliding seat 68 by the fourth shaft 23 moves leftward and increases in height, the left end of the second flap 18 increases in height, and the right end of the first flap 13 also increases in height;

[0032] S6, the brake motor 37 continues to rotate clockwise until the sliding seat 68 of the sliding seat assembly 32 triggers the first switch 28, causing the first switch 28 to be disconnected, the coil KM1 to lose power, the normally open contact KM1 of the contactor to be disconnected, and the brake motor 37 stops rotating. At this time, the right end of the first flap 13 and the left end of the second flap 18 rise to the set height. Since the lower surfaces of the first dustproof plate 2 and the second dustproof plate 8 are respectively attached to the upper surfaces of the first flap 13 and the second flap 18, they also rise accordingly. At this time, the vehicle is in a blocking state.

[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0034] 1. In the present invention, the vehicle blocking device can achieve two-way blocking by blocking through the linked first flap and second flap.

[0035] 2. In the present invention, the dust removal brush of the blocking device will sweep the dust and other debris in the base into the dust removal hole at the bottom of the base when the sliding seat assembly moves left and right, so that the base is kept clean.

[0036] 3. In the present invention, by adjusting the installation position of the first switch on the base to the left or right, the height of the blocking device when blocking the vehicle can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The device is installed in parking spaces, parking lot entrances, community gates, checkpoints where vehicles need to be prevented from entering, traffic light intersections, elevator doors, etc.

[0053] The device is installed on the road or parking space where vehicles pass. It can be used alone or multiple sets can be spliced ​​together. When used in parking spaces, two sets can be installed near the wall of a parking space to prevent vehicles from hitting the wall. When used in a three-dimensional parking space, four sets can be installed to prevent vehicles from accidentally moving forward or backward. When used at the door of an underground garage, it is best to use a row for the entire door, which can prevent water from entering the garage while blocking vehicles. When used in an elevator, it can be installed inside the car, outside the hall door, or inside and outside the hall door at the same time. Different installation locations protect different parts of the elevator. The one installed inside the car protects vehicles inside the car from hitting the elevator car door, and the one installed outside the hall door protects vehicles outside from hitting the elevator hall door.

[0054] When installed inside the car, the fixing parts are passed through the first through hole 7 reserved on the device and fixed to the car bottom steel at the bottom of the car, while ensuring that when the device is in the passing state, the upper surfaces of the first dustproof plate 2 and the second dustproof plate 8 are flush with the upper surface of the car bottom.

[0055] When installed outside the hall door, the fixing parts are passed through the first through hole 7 reserved on the device and fixed to the pre-buried parts buried underground in advance, and at the same time, it is ensured that when the device is in the traffic state, the upper surface of the first dustproof plate 2 and the second dustproof plate 8 are flush with the upper surface of the vehicle. Fig.10 shown.

[0056] The number of devices to be installed should be determined based on the actual situation on site. Generally, four sets are installed inside the car and two sets are installed outside the hall door. The ones installed inside the car are used to block the front and rear wheels of the vehicle to prevent the vehicle from accidentally moving forward or backward and hitting the elevator car door or the rear car wall. The ones installed outside the hall door are used to block the front wheels of the vehicle to prevent the vehicle from accidentally hitting the elevator hall door.

[0057] Example 1

[0058] The four devices installed inside the car are connected in parallel and work at the same time. The switches are the car door switches or the car door closed switches. The two devices installed outside each hall door are connected in parallel and work at the same time. The switches are the hall door switches or the hall door closed switches. Fig. 9 shown.

[0059] When the car is leveled, the elevator door is opened, the switch SW is disconnected, the coil KM loses power, the normally open contact KMA of the contactor is disconnected, and the normally closed contact KMB of the contactor is closed. When the sound and light control switch is working, the L1 (forward) circuit of the brake motor 37 is disconnected, and the L2 (reverse) circuit is closed.

[0060] At this time, ① if the second switch 30 is in the closed state, the coil KM2 is energized, the normally open contact KM2 of the contactor is in the closed state, the L2 (reverse) circuit of the brake motor 37 is closed, and the brake motor 37 reverses, driving the transmission rod 34 to rotate. The rotation of the transmission rod 34 drives the sliding seat assembly 32 to move to the right along the first slide bar 33 and the second slide bar 35. At this time, the lower end of the support plate 15 connected to the sliding seat 68 by the fourth shaft 23 moves to the right, and the height is reduced. Since the upper end of the support plate 15 is connected to the second flap 18 by the third shaft 22, the two ends of the third shaft 22 are inserted into the first anti-wear sleeve 14 in the sliding groove 26 on the bending surfaces on both sides of the first flap 13, the height of the left end of the second flap 18 is reduced, the first anti-wear sleeve 14 will move in the sliding groove 26, and the height of the right end of the first flap 13 is also reduced. As the brake motor 37 continues to reverse, until the sliding seat 68 of the sliding seat assembly 32 triggers the second switch 30 to disconnect it, the coil KM2 loses power, the normally open contact KM2 of the contactor is disconnected, and the brake motor 37 stops rotating. At this time, the upper surfaces of the first flap 13 and the second flap 18 are just in a horizontal state, and the upper surfaces of the first dustproof plate 2 and the second dustproof plate 8 are just flush with the upper surface of the car bottom. At this time, the vehicle is in a state of passage, such as Fig.10 ② If the second switch 30 is in the disconnected state, the coil KM2 loses power, the normally open contact KM2 of the contactor is in the disconnected state, the L2 (reverse) circuit of the brake motor 37 is disconnected, and the brake motor 37 does not rotate. At this time, it is necessary to check the blocking device and eliminate the fault.

[0061] When the car is leveled, the elevator car door is fully closed, the switch SW is closed, the coil KM is energized, the normally open contact KMA of the contactor is closed, and the normally closed contact KMB of the contactor is disconnected. When the sound and light control switch is working, the L1 (forward) circuit of the brake motor 37 is closed, and the L2 (reverse) circuit is disconnected.

[0062] At this time, ① if the first switch 28 is in the closed state, the coil KM1 is energized, the normally open contact KM1 of the contactor is in the closed state, the L1 (forward rotation) circuit of the brake motor 37 is closed, and the brake motor 37 rotates forward, driving the transmission rod (threaded rod or ball screw) 34 to rotate. The rotation of the transmission rod (threaded rod or ball screw) 34 drives the sliding seat assembly 32 to move to the left along the first slide bar 33 and the second slide bar 35. At this time, the lower end of the support plate 15 connected to the sliding seat 68 by the fourth shaft 23 moves to the left and the height increases. Since the upper end of the support plate 15 is connected to the second flap 18 by the third shaft 22, the two ends of the third shaft 22 are inserted into the first anti-wear sleeve 14 in the sliding groove 26 on both sides of the first flap 13. The height of the left end of the second flap 18 increases, the first anti-wear sleeve 14 will move in the sliding groove 26, and the height of the right end of the first flap 13 also increases. As the brake motor 37 continues to rotate clockwise until the sliding seat 68 of the sliding seat assembly 32 triggers the first switch 28 to disconnect it, the coil KM1 loses power, the normally open contact KM1 of the contactor is disconnected, and the brake motor 37 stops rotating. At this time, the right end of the first flap 13 and the left end of the second flap 18 just rise to the set height. Since the lower surfaces of the first dustproof plate 2 and the second dustproof plate 8 are respectively attached to the upper surfaces of the first flap 13 and the second flap 18, they also rise accordingly. At this time, the vehicle is in a blocking state, such as Figure 1 ② If the first switch 28 is in the disconnected state, the coil KM1 loses power, the normally open contact KM1 of the contactor is in the disconnected state, the L1 (forward) circuit of the brake motor 37 is disconnected, and the brake motor 37 does not rotate. At this time, it is necessary to check the blocking device and eliminate the fault.

[0063] Example 2

[0064] When this blocking device is installed outside the hall door, the working principle is the same as when it is installed inside the car. When the car is leveled: (1) The elevator hall door is opened, the switch SW is disconnected, the coil KM loses power, the normally open contact KMA of the contactor is disconnected, the normally closed contact KMB of the contactor is closed, and when the sound and light control switch works, the door gate control box DK is energized, the gate railing is raised, and the blocking device is in the vehicle passing state; (2) The elevator hall door is fully closed, the switch SW is closed, the coil KM is energized, the normally open contact KMA of the contactor is closed, the normally closed contact KMB of the contactor is disconnected, and when the sound and light control switch works, the door gate control box DK loses power, the gate railing is lowered, and the blocking device is in the vehicle blocking state.

[0065] Example 3

[0066] When this blocking device is installed at the door of the underground garage, the on and off of the switch SW is controlled by the license plate scanner. When the vehicle scans the license plate successfully, the switch SW is disconnected, and the blocking device is in the vehicle passing state. On the contrary, the switch SW is closed, and the blocking device is in the vehicle blocking state. When the blocking device is flooded and triggers the float switch 39, the float switch 39 is turned on, the coil KM3 is energized, the contactor normally open contacts KM3.1 and KM3.2 are closed, the contactor normally closed contacts KM3.3 and KM3.4 are disconnected, the water pump 40 is started to drain water, the L1 (forward) circuit of the brake motor 37 is closed, and the brake motor 37 rotates forward, turning the blocking device in the passing state into the blocking state, and blocking water from flowing into the underground garage. At this time, if a vehicle comes out of the underground garage, it is necessary to press the delay switch 70, the delay switch 70 is turned on, the coil KM4 is energized, the contactor normally closed contact KM4.1 is disconnected, and the contactor normally open contacts KM4.2 and KM4.3 are closed. The normally open contact KM4.2 of the contactor is closed, the L2 (reverse) circuit of the brake motor 37 is closed, and the brake motor 37 is reversed, turning the blocking device in the blocking state into the pass state. The normally open contact KM4.3 of the contactor is closed, the gate control box DK is energized, the gate railing is lifted, and the vehicle is released. The delay switch 70 will be disconnected after the set delay time, and the blocking device will be turned into the blocking state again, and the gate railing will be lowered to block the vehicle. When the water is drained, the float switch 39 is disconnected, and the blocking device returns to the previous non-drainage state.

[0067] Example 4

[0068] When the blocking device is installed at a red light or green light intersection, the on and off of the switch SW should be controlled by the red light or green light control system, so as to control the blocking device to be in a vehicle passing state or a vehicle blocking state.

[0069] Working principle: When the blocking device is in the vehicle blocking state, the first flap 13, the support plate 15, the second flap 18, the base 9 and the transmission guide system 5 form a plurality of triangles, so that the blocking device has a high degree of stability. Figure 1 , Figure 3 As shown; when the blocking device is in a vehicle passing state, the two first anti-wear sleeves 14 fall into the upper ends of the front and rear side surfaces of the base 9 and the left limiting groove 44, and their surfaces coincide with each other. Since the boss of the first anti-wear sleeve 14 is located inside the bending edge of the first flap 13 and outside the second flap 18, the movement along the third axis 22 is restricted, and the upper parts of the front and rear side surfaces of the base 9 are also located inside the bending edge of the first flap 13 and outside the second flap 18 (that is, between the bending edge of the first flap 13 and the second flap 18), so that the blocking device is quite stable when the vehicle is passing.

[0070] In addition, the installation position of the first switch 28 on the base 9 can be adjusted left or right according to actual needs on site, so as to adjust the height of the blocking device when blocking the vehicle.

[0071] The dust removal brush 64 of the blocking device will sweep the dust and other debris in the base 9 into the dust removal hole 47 at the bottom of the base 9 when the sliding seat assembly 32 moves left and right, so that the base 9 is kept clean.

[0072] The drainage system 6, sound and light control switch, delayed release function, etc. of this blocking device can be flexibly selected according to the actual situation on site. The main function of the sound and light control switch is to cut off the power supply when the blocking device is in a non-working state, save energy, increase the service life of the equipment, and reduce the cost of use.

[0073] The action of this device is linked with doors, gates, traffic lights, etc. When the doors, gates, etc. are not opened and the traffic lights are red, this device is in a blocking state. When the doors, gates, etc. are opened and the traffic lights are green, this device is in a releasing state and remains flush with the upper surface of the vehicle passage, which can effectively and conveniently solve the problem of collision when the vehicle moves forward or backward. When a certain amount of water enters this device, the drainage system of this device will be activated to drain water. At this time, this device will also be activated and in a blocking state to prevent water from entering the garage, etc. This function is especially suitable for the entrance of the underground garage to prevent the garage from flooding and vehicles from entering the underground garage at this time. If this device is installed on the parking space of the underground garage, the garage will be flooded at this time, and this device will start the drainage system at any time to drain water. It can also start the drainage system without starting the blocking function as needed.
