Description

Technical Field

[0001] This utility model relates to the field of vehicle interception devices, and in particular to a vehicle blocking component and a vehicle blocking device. Background Technology

[0002] As an important auxiliary device in road vehicle inspection scenarios (such as checkpoint inspections, security deployment, and fixed-point inspections), vehicle blocking devices must simultaneously meet four core requirements: rapid deployment, forced interception, personnel safety, and scenario adaptability. However, existing vehicle blocking devices have some limitations. For example, in-ground vehicle blocking devices require road surface damage for installation, making them unsuitable for flexible deployment at temporary checkpoints; fence-type vehicle blocking devices are not portable, often requiring ample space for placement when carried; and traditional tire-puncturing vehicle blocking devices (such as concealed puncture devices) can easily cause vehicles to lose control and overturn after a tire is punctured due to the instantaneous loss of pressure.

[0003] Therefore, how to balance the portability of vehicle stoppers with their reliability is a research topic of great practical significance. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a vehicle blocking component and device that is convenient to store, reliable to use, and has a good vehicle blocking effect.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A vehicle-stopping assembly includes two pairs of opposing wheel-stopping mechanisms, each pair corresponding to a wheel of a vehicle; the wheel-stopping mechanism includes:

[0007] A stopping frame with a stopping area on its upper part, and guide ramps for guiding wheels to enter or exit are connected to both ends of the stopping frame.

[0008] The connecting frame is a frame structure that can be raised and lowered in the retention area of ​​the retention frame. Multiple rollers are rotatably connected inside the frame structure of the connecting frame. The retention area of ​​the retention frame is provided with a clearance groove corresponding to the connecting frame and the rollers connected thereon.

[0009] The lifting drive mechanism is a hydraulic drive mechanism, which is located at the lower part of the retention frame and connected to the connecting frame. The lifting drive mechanism drives the connecting frame to lift and lower, so that the roller on the connecting frame has a first state of being higher than the avoidance trough and a second state of being contained in the avoidance trough.

[0010] The controller is connected to the lifting drive mechanism and controls its working actions;

[0011] The lifting drive mechanisms of the two pairs of wheel braking mechanisms are connected sequentially through hydraulic circuits and are controlled by a controller.

[0012] As one possible implementation, the connecting frame described in this solution is further provided with a plurality of upwardly protruding sharp parts on one side of the front end.

[0013] As one possible implementation, the retention area of ​​the retention frame described in this solution is provided with a plurality of support blocks arranged in an array, wherein a clearance groove for the lifting and lowering of the clearance roller is formed between adjacent rows of support blocks.

[0014] As a possible implementation, the retention frame in this solution is further provided with connecting rods on both sides, the two ends of the connecting rods being connected to the sides of the guide slope plates at both ends of the retention frame, and the middle part of the connecting rods being higher than the upper end surface of the retention frame.

[0015] As a preferred implementation option, the lifting drive mechanism of this solution includes two pairs of lifting cylinders, which are respectively arranged opposite each other at the corners of the retention area of ​​the retention frame. The main body of the lifting cylinder is fixedly connected to the retention frame, and its lifting drive end faces upward and is connected to the corner of the connecting frame. The connecting frame is lifted and lowered by the synchronous lifting of the two pairs of lifting cylinders. Both pairs of lifting cylinders are connected to the same hydraulic circuit and are controlled by a controller.

[0016] As a preferred implementation option, the inner side of the connecting frame of this solution is further provided with two pairs of opposing limiting pins, and the support block near the limiting pins is provided with a lifting limiting groove. One end of the limiting pin is fixed on the connecting frame, and the other end is movably inserted into the lifting limiting groove.

[0017] As a preferred implementation option, the outer side of the connecting frame in this solution is further provided with two pairs of opposing springs. One end of the spring is connected to the connecting frame, and the other end of the spring extends downward and is connected to the lower side of the retention frame. When the connecting frame rises to the point where the roller is higher than the clearance trough, the spring is in a stretched state.

[0018] As a preferred implementation option, the bottom of the stopping frame in this solution is also provided with an anti-slip pad; the lifting drive mechanism of the two pairs of wheel stopping mechanisms is detachably connected to the hydraulic oil circuit; the controller is also provided with a wireless communication module, which is used to receive remote control commands.

[0019] Based on the above, this solution also proposes a vehicle blocking device, which includes the vehicle blocking component described above; it also includes a front vehicle blocking component, which includes multiple vehicle blocking frames connected in sequence by scissor-type linkages.

[0020] As a preferred implementation option, the vehicle barrier of this solution preferably includes an L-shaped main body, the lower end of which is connected to a support, and an extension extending downward at an angle on one side of the lower part of the L-shape of the main body.

[0021] Compared with the prior art, the present invention has the following advantages when using the above-mentioned technical solution: The ingenious design uses two pairs of opposing wheel-stopping mechanisms to impede the movement of vehicle wheels. The passive rotation of the rollers reduces the wheel output power when the vehicle starts, increasing the difficulty for the vehicle to start and leave before the rollers contact the wheels when the vehicle enters the wheel-stopping mechanism, thus improving the safety of the inspection personnel. Furthermore, a front-mounted blocking component can be installed in front of the vehicle, which can engage with the lower part of the front bumper after the vehicle is parked to prevent sudden starts and departures, improving the reliability of vehicle parking during inspections. When deployed on-site, the device only requires simple assembly of a few components, making it reliable and flexible. When not in use, it can be disassembled or folded for storage, improving its portability. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0034] like Figures 1 to 5 As shown in one embodiment, a vehicle-stopping assembly includes two pairs of opposing wheel-stopping mechanisms 1, each pair corresponding to a wheel 10 of a vehicle; the wheel-stopping mechanism 1 includes:

[0035] The retention frame 2 has a retention area 21 on its upper part, and both ends of the retention frame 2 are connected to guide ramps 22 for guiding the wheels 10 to enter or drive out.

[0036] The connecting frame 23 is a frame structure that is vertically and flexibly installed in the retention area 21 of the retention frame 2. Multiple rollers 24 are rotatably connected inside the frame structure of the connecting frame 23. The retention area 21 of the retention frame 2 is provided with a clearance groove 25 corresponding to the connecting frame 23 and the rollers 24 connected thereon.

[0037] The lifting drive mechanism 3 is a hydraulic drive mechanism, which is located at the lower part of the retention frame 2 and connected to the connecting frame 23. The lifting drive mechanism 3 drives the connecting frame 23 to rise and fall, so that the roller 24 on the connecting frame 23 is in a first state that is higher than the clearance trough 25 (see reference). Figure 5 and the second state contained within the avoidance trough 25 (refer to) Figure 4 );

[0038] The controller 11 is connected to the lifting drive mechanism 3 and controls its working actions;

[0039] Among them, the lifting drive mechanisms 3 of the two pairs of wheel blocking mechanisms 1 are connected in sequence through hydraulic oil circuits 32 and are controlled by controller 11.

[0040] In this solution, to prevent the vehicle from suddenly starting and running while parked, as a possible implementation method, the connecting frame 23 of this solution is further provided with a plurality of upwardly protruding sharp parts 26 on one side of the front end; the sharp parts 26 can be detachable installation structures.

[0041] To improve the reliability of the lifting and lowering of the roller 24 driven by the connecting frame 23, without interfering with the retention and support effect of the retention area 21, as a possible implementation, the retention area 21 of the retention frame 2 is provided with a plurality of support blocks 27 arranged in an array, wherein a clearance groove 25 is formed between adjacent rows of support blocks 27 to avoid the lifting and lowering of the roller 24; that is, in this embodiment, the clearance groove 25 is formed by the gap between the support blocks 27 deployed in an array structure.

[0042] To facilitate the positioning and marking of the retention area 21, as a possible implementation, the retention frame 2 in this solution is further provided with connecting rods 28 on both sides. The two ends of the connecting rods 28 are respectively connected to the sides of the guide slope plates 22 at both ends of the retention frame 2, and the middle part of the connecting rods 28 is higher than the upper end surface of the retention frame 2.

[0043] Regarding the lifting drive, as a preferred implementation option, the lifting drive mechanism 3 of this solution preferably includes two pairs of lifting cylinders 31, which are respectively arranged opposite each other at the corners of the retention area 21 of the retention frame 2. The main body of the lifting cylinder 31 is fixedly connected to the retention frame 2, and its lifting drive end faces upward and is connected to the corner of the connecting frame 23. The connecting frame 23 is lifted and lowered by the synchronous lifting of the two pairs of lifting cylinders 31. Both pairs of lifting cylinders 31 are connected to the same hydraulic circuit 32 and are controlled by the controller 11.

[0044] To prevent the connecting frame 23 from shifting significantly or detaching during lifting, as a preferred implementation, the inner side of the connecting frame 23 is preferably provided with two pairs of opposing limiting pins 231. A lifting limiting groove 232 is provided on the support block 27 near the limiting pins 231. One end of each limiting pin 231 is fixed to the connecting frame 23, and the other end is movably inserted into the lifting limiting groove 232. Simultaneously, the outer side of the connecting frame 23 is provided with two pairs of opposing springs 29. One end of each spring 29 is connected to the connecting frame 23, and the other end extends downward and connects to the lower side of the retaining frame 2. When the connecting frame 23 rises until the roller 24 is higher than the clearance groove 25, the springs 29 are in a stretched state. When the lifting cylinder 31 stops holding pressure and lowers the connecting frame 23, the springs 29 provide some assistance in promoting repositioning.

[0045] To prevent the components of this solution from slipping during use, as a preferred implementation option, the bottom of the retention rack 2 described in this solution may also be provided with anti-slip pads or other anti-slip components.

[0046] To improve the ease of storage and assembly of the device, the oil circuit connection between the lifting drive mechanism 3 of the two pairs of wheel blocking mechanisms 1 and the hydraulic oil circuit 31 can be a detachable connection, which can be connected through quick-connect pipe fittings, so that it can be easily removed when not in use. In order to facilitate non-contact control, the controller 11 of this solution is also equipped with a wireless communication module to receive remote control commands. In this way, the components can be controlled more flexibly.

[0047] exist Figures 1 to 5 Based on what is shown, further combine Figures 6 to 9 As shown in one example, this solution also proposes a vehicle blocking device, which includes the vehicle blocking component 1 described above; it also includes a front vehicle blocking component 4, which includes a plurality of vehicle blocking frames connected in sequence by scissor-type connecting rods 44.

[0048] In terms of structure, as a preferred implementation option, the vehicle blocking frame 41 of this solution preferably includes an L-shaped main body, with a support portion 42 connected to the lower end of the main body, and an extension portion 43 extending downward at an angle on one side of the lower part of the L-shape of the main body; in implementation, it is used to engage with the lower part of the front bumper of the car 5 to prevent the vehicle from suddenly starting and moving (see reference). Figure 8 ).

[0049] Combination Figure 10As shown, another type of front blocking assembly 4 of this solution is illustrated. To facilitate maintaining the unfolded shape of the blocking frame 41, this solution also includes a detachable limiting member 45, which includes a crossbar 451 and pins 453. The crossbar 451 passes through multiple blocking frames 41 of the front blocking assembly 4 in sequence. Multiple through holes 454 are provided at intervals on the crossbar 451. Multiple pins 453 are inserted into the through holes 454 to limit the deformation state of the multiple blocking frames 41 of the front blocking assembly 4 after unfolding. The blocking frame 41 is provided with through holes 452 corresponding to the crossbar 451 for it to pass through. The limiting member 45 can improve the maintenance of the front blocking assembly 4 during use.

[0050] When implementing this solution, the user can place two pairs of wheel blocking mechanisms 1 opposite each other on the ground, then connect the lifting cylinder 31 of the lifting drive mechanism 3 to the hydraulic circuit 32 (connected to the hydraulic pump system), and then guide the vehicle to be inspected to drive into the stopping area 21 of the wheel blocking mechanism 1 to stop. The controller 11 controls the lifting cylinder 31 to rise and maintain pressure through the hydraulic pump system, so that the vehicle's wheels 10 contact the roller 24. In this case, the rotating roller 24 will rotate to counteract the tire rotation (output driving force) when the vehicle starts, so that the wheels 10 cannot drive the vehicle forward, thus preventing the driver from suddenly starting the vehicle and driving away. The front blocking component 4 can be locked into the lower part of the front bumper of the car 5 after the vehicle is parked to prevent the vehicle from suddenly starting and driving away, thus improving the reliability of vehicle parking during inspection.

Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
