[0011] Preferably, the fixing frame is L-shaped, and one end of the fixing frame away from the vertical rod is rotatably mounted on the winding rod, and limiting components for limiting the angle of the winding rod are provided on both symmetrical sides of the winding rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention facilitates the enhancement of the stability of the lifting column body by arranging the cooperation of structures such as the installation box and the gravity block adjustment component, thereby increasing the friction with the ground and achieving a certain buffering effect. When a vehicle impacts the lifting column body, the adjustment component is driven to automatically adjust, and the bottom support plate is driven to contact the ground by utilizing the gravity effect of the gravity block itself. At the same time, through the cooperation between the support rod at the bottom of the support plate and the tripod, according to the principle of higher stability of the triangle, the stability of the support plate is further improved, the friction with the ground is increased, and then the stability of the lifting column body and the ground is enhanced, which solves the problem that when the existing lifting blocking device is blocked by the lifting column body, due to its relatively simple structure and lack of corresponding blocking buffer components, when the vehicle is out of control, the lifting column body may be directly broken or the lifting column body may be damaged, affecting subsequent use.

[0019] The present invention facilitates the rapid adjustment of the position of the support plate by arranging the coordination of structures such as the winding rod, the connecting rope, the fixing frame and the limiting assembly. By utilizing the coordinated use of the adjusting assembly and the limiting assembly, when the vehicle hits the lifting column body, the limiting assembly on the winding rod disappears. At this time, the gravity block slides downward inside the installation box due to its own gravity effect, driving the connecting rope to slide along the routing ring, thereby causing the winding rod to rotate and release the wire, so that the support plate contacts the ground. During the contact process, the gravity block applies gravity, which increases the friction between the support plate and the ground, increases the resistance to the vehicle, and has a certain buffering effect on the impact force of the vehicle, thereby reducing the degree of damage to the vehicle and the lifting column body caused by the collision.

[0020] The present invention provides a fixed block, a rotating block, an adjusting block, a spring and other structures to facilitate the support plate to fall to the ground quickly when a vehicle collides, and also realizes the rapid limitation of the winding rod. The initial state of the support plate is in close contact with the bottom of the installation box, the connecting rope is in a taut state and is completely wound around the winding rod, the limiting rod is clamped in the clamping groove, the rotating block and the fixed block are in contact with each other, so as to ensure the fixing of the winding rod angle. At this time, the spring is in an extended state. When the lifting column body is impacted, since the adjusting block is in an arc shape and the lifting column body is mostly arranged at the center of the basement, when the vehicle When the lifting column body is impacted out of control, the impact force at the center is relatively large. When the vehicle impacts along the center of the lifting column body, the adjusting block will be squeezed to make it rotate to both sides away from each other. At this time, the spring pay-off is twisted and compressed, the rotating block moves away from the fixed block, and the limit rod is pulled out of the slot, thereby losing the limiting force on the winding rod. At this time, the connecting rope will move downward under the influence of the gravity of the gravity block and drive the winding rod to rotate along the fixed frame until the support plate contacts the ground, thereby preventing it from being affected by the gravity block and dragged at the bottom of the lifting column body to shake, making it inconvenient to lift the lifting column body.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0033] like Figures 1 to 10 As shown, the present invention provides a lifting type blocking device for preventing intrusion at a basement entrance, comprising a column 1, a lifting column body 2 is hingedly connected to the side of the column 1, the lifting column body 2 comprises a cross bar 21, a plurality of vertical bars 22 arranged in a longitudinal direction are fixedly connected to the cross bar 21, a wiring ring 221 is fixedly connected to the top of the plurality of vertical bars 22, a buffer mechanism 3 is arranged on the lifting column body 2; the buffer mechanism 3 comprises a plurality of mounting boxes 31, the plurality of mounting boxes 31 are fixedly connected to the surface of the vertical bars 22, a sliding column 32 and a gravity block 35 are slidably connected inside the plurality of mounting boxes 31, a support plate 33 that can contact the ground is arranged at the bottom of the plurality of sliding columns 32, A fixing plate 34 is fixedly connected to the multiple gravity blocks 35. An adjustment component 36 for adjusting the position of the gravity blocks 35 is provided on the side of the lifting column body 2 away from the installation box 31. A slide groove 311 is provided on the installation box 31. The fixed plate 34 slides in the slide groove 311. The gravity blocks 35, the sliding column 32 and the support plate 33 are arranged in sequence from top to bottom along the direction of the installation box 31. The gravity blocks 35, the sliding column 32 and the support plate 33 are all provided in plurality and arranged in a linear array. A plurality of support rods 331 are fixedly connected to the bottom of the support plate 33. At least three tripods 332 distributed in a circular array are fixedly connected to the multiple support rods 331.

[0034] The above scheme is adopted: when in use, the lifting and lowering of the lifting column body 2 is achieved by adjusting the angle between the column 1 and the lifting column body 2. This is a feature of the prior art. When the lifting column body 2 is used to block a vehicle, in order to prevent the vehicle from losing control and directly breaking in, the vehicle speed can be buffered by utilizing the buffer mechanism 3. When the vehicle impacts the lifting column body 2, the adjustment component 36 is driven to automatically adjust, and the bottom support plate 33 is driven to contact the ground by utilizing the gravity effect of the gravity block 35 itself. At the same time, through the cooperation between the support rod 331 and the tripod 332 at the bottom of the support plate 33, according to the principle of higher stability of the triangle, the stability of the support plate 33 is further improved, the friction with the ground is increased, and the stability of the lifting column body 2 and the ground is enhanced.

[0035] like Figure 4 As shown, the adjustment component 36 includes a winding rod 361, on which multiple groups of connecting ropes 362 are wound, and the multiple groups of connecting ropes 362 all pass through the wiring ring 221, and fixed frames 363 are provided at both symmetrical ends of the winding rod 361, and the side of the fixing frame 363 away from the winding rod 361 is fixedly connected to the vertical rod 22, and the fixing frame 363 is L-shaped, and the end of the fixing frame 363 away from the vertical rod 22 is rotatably sleeved on the winding rod 361, and the symmetrical sides of the winding rod 361 are provided with limit assemblies 37 for limiting the angle of the winding rod 361, one end of the multiple groups of connecting ropes 362 is fixedly connected to the outer wall of the winding rod 361, and the end of the multiple groups of connecting ropes 362 away from the winding rod 361 vertically downward and sequentially pass through the gravity block 35, the sliding column 32 and the support plate 33, and the multiple groups of connecting ropes 362 are fixedly connected to the gravity block 35, the sliding column 32 and the support plate 33.

[0036] By adopting the above scheme: by utilizing the coordinated use of the adjustment component 36 and the limit component 37, when the vehicle hits the lifting column body 2, the limit component 37 on the winding rod 361 disappears, and at this time, the gravity block 35 slides downward inside the installation box 31 due to its own gravity effect, driving the connecting rope 362 to slide along the routing ring 221, thereby causing the winding rod 361 to rotate and release the wire, so that the support plate 33 contacts the ground. During the contact process, the gravity block 35 applies gravity, which increases the friction between the support plate 33 and the ground, increases the resistance to the vehicle, and has a certain buffering effect on the impact force of the vehicle, thereby reducing the degree of damage to the vehicle and the lifting column body 2 caused by the collision.

[0037] like Figure 5As shown, the limiting assembly 37 includes two symmetrical fixed blocks 371, and the two fixed blocks 371 are both clamped with a rotating block 372. The fixed block 371 and the rotating block 372 are both L-shaped and are clamped with each other on one side in the horizontal direction. A slot 3711 is provided on one side in the horizontal direction of the fixed block 371, and a limiting rod 3721 is clamped on the slot 3711. The limiting rod 3721 is fixedly connected to one side in the horizontal direction of the rotating block 372. The two rotating blocks 372 are fixedly connected with an adjusting block 373 on one side away from the fixed block 371, and the two rotating blocks 372 are far away from each other. A connecting plate 374 is hinged on one side of the two connecting plates 374, and a transverse plate 375 is fixedly connected to the fixed frame 363 on one side away from the rotating block 372. The transverse plate 375 is fixedly connected to the fixed frame 363. The two adjustment blocks 373 are both arc-shaped and the bending directions of the symmetrical sides are opposite. A spring 376 is fixedly connected to the side of the transverse plate 375 close to the rotating block 372, and the end of the spring 376 away from the transverse plate 375 is fixedly connected to the adjusting block 373. There are multiple rotating blocks 372 arranged longitudinally, and connecting rods 377 are fixedly connected to the multiple rotating blocks 372.

[0038] The above scheme is adopted: the winding rod 361 is limited by the limiting assembly 37, thereby limiting the position of the support plate 33, avoiding the support plate 33 being affected by the gravity block 35 and dragged at the bottom of the lifting column body 2 to shake, which is inconvenient for the lifting column body 2 to rise and fall. The initial state of the support plate 33 is close to the bottom of the installation box 31, the connecting rope 362 is in a taut state and is completely wound around the winding rod 361, the limiting rod 3721 is clamped in the clamping groove 3711, the rotating block 372 and the fixing block 371 are in contact with each other, ensuring the fixing of the angle of the winding rod 361, and the spring 376 is in an extended state. When the lifting column body 2 is impacted, due to the adjustment The block 373 is in an arc shape, and the lifting column body 2 is mostly arranged at the center of the basement. When a vehicle loses control and impacts the lifting column body 2, the impact force at the center is relatively large. When the vehicle impacts along the center of the lifting column body 2, it will squeeze the adjustment block 373 to make it rotate to both sides away from each other. At this time, the spring 376 is twisted and compressed when the wire is released, and the rotating block 372 is away from the fixed block 371. The limiting rod 3721 is pulled out of the slot 3711, thereby losing the limiting force on the winding rod 361. At this time, the connecting rope 362 will be affected by the gravity of the gravity block 35 and move downward, driving the winding rod 361 to rotate along the fixing frame 363 until the support plate 33 contacts the ground.

[0039] like Figure 8As shown, a protective mechanism 4 is provided on one side of the lifting column body 2 close to the mounting box 31, and the protective mechanism 4 is used to protect the connecting rope 362. The protective mechanism 4 includes a protective shed 41, and a driving rod 43 is fixedly connected to one side of the protective shed 41. A mounting plate 42 is hinged on the side of the driving rod 43 away from the protective shed 41, and the mounting plate 42 is fixedly connected to the vertical rod 22. One end of the driving rod 43 is fixedly connected to a motor 44, and a supporting plate is fixedly connected to the side of the mounting plate 42, and the supporting plate is fixedly connected to the motor 44.

[0040] The above scheme is adopted: by utilizing the protective mechanism 4, when in use, since most underground garages are in disrepair for a long time, when encountering heavy rain or humid weather, water seepage or leakage is likely to occur at the entrance, which will cause the connecting rope 362 to become damp, increasing the resistance between it and the winding rod 361, and affecting its descent speed. The connecting rope 362 can be protected by utilizing the protective shed 41. When encountering rainy weather, the driving rod 43 and the protective shed 41 are driven by the motor 44 to rotate along the mounting plate 42, so that it is perpendicular to the top of the mounting plate 42, covering the connecting rope 362 to avoid being affected by rain, thereby ensuring the descent speed of the connecting rope 362.

[0041] The working principle and use process of the present invention are as follows: when using the device, the lifting and lowering of the lifting column body 2 is achieved by adjusting the angle between the column 1 and the lifting column body 2. This is a feature of the prior art. When using the lifting column body 2 to block a vehicle, in order to prevent the vehicle from losing control and directly breaking in, the vehicle speed can be buffered by using the buffer mechanism 3. When the vehicle impacts the lifting column body 2, when the vehicle loses control and impacts the lifting column body 2, the impact force at the center is relatively large. Therefore, when the vehicle impacts along the center of the lifting column body 2, the adjustment block 373 will be rotated on both sides. At this time, the spring 376 is twisted and compressed during the release of the wire. The rotating block 372 moves away from the fixed block 371, and the limiting rod 3721 is drawn out of the slot 3711, thereby losing the limiting force on the winding rod 361. At this time, the gravity block 35 The lifting column body 2 is then lifted up and the support plate 33 is in contact with the ground.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
