Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to an obliquely hung lifting platform with an anti-collision structure. Background Art

[0002] By adding guide rails to the railings or walls on both sides of the steps, the inclined lifting platform can be cleverly installed in places that are not suitable for ramps and elevators, such as subway entrances and exits, underground sidewalks, pedestrian bridges, and railway station entrances and exits, without damaging the stair surface and appearance. It can be folded and placed when not in use, without affecting the normal use of the space.

[0003] According to the disclosed anti-collision device for the pedal of an intelligent oblique-hanging lifting platform (publication number: CN211110539U), in the above application, when a mechanical failure occurs, the platform loses its braking force, causing one end of the base plate to hit the step. At this time, the fixed block on one side of the base plate contacts the step surface and is subjected to impact force, and the baffle in the rectangular groove on the front side of the fixed block is pressed to contract the spring, and causes the telescopic rod to retract toward the buffer seat. When the spring is compressed to the critical point of the elastic force, it rebounds from the bottom with the help of the fixed block as support, and uses the elastic force of the spring to resist the impact force on the buffer baffle. When the spring rebounds, it pushes the baffle and the telescopic rod outward, and the rubber plug at the bottom of the telescopic rod rubs and unloads force in the buffer seat, buffering the rebound force of the spring, thereby preventing the wheelchair on the base plate from being transmitted with excessive impact force, thereby solving the problem that the existing intelligent oblique-hanging lifting platform pedal cannot protect against collision.

[0004] The device uses the combination of baffles and springs to reduce the impact force transmitted by the base plate to the wheelchair. However, when the base plate is hit, the wheelchair will lose its stability and may move. Once the wheelchair moves, it may cause the user's legs to collide with the backboard, or the body parts to collide with the railing, posing a safety hazard. Utility Model Content

[0005] The purpose of the utility model is to provide an obliquely hung lifting platform with an anti-collision structure to solve the problems raised in the above background technology.

By providing the positioning mechanism, the large wheels of the wheelchair can be limited to prevent the lifting platform from being hit and causing the wheelchair to move. An auxiliary mechanism is provided on the bottom plate, which can provide a double protection effect for the wheelchair and effectively prevent the wheelchair from moving. The positioning mechanism comprises:

[0007] A threaded rod, one end of which is rotatably connected to the inner wall of the base plate, the other end of which is fixedly mounted with a handwheel, and the outer wall of which is threadedly connected with a slider;

[0008] An L-rod, the L-rod being slidably connected to the inner wall of the bottom plate, a connecting rod being hinged on the top of the L-rod, an end of the connecting rod away from the L-rod being hinged on the side wall of the slider, and the L-rod being provided to push and pull the connecting rod;

[0009] The support plate is hinged on the inner wall of the groove, and a connecting rod is hinged on the bottom of the support plate. The end of the connecting rod away from the support plate is hinged on the side wall of the L rod. By setting the support plate, the large wheels of the wheelchair can be limited.

[0010] Preferably, the auxiliary mechanism includes a limit plate, which is slidably connected to the inner wall of the base plate. Two groups of limit plates are provided, and the two groups of limit plates are mirror-imaged on both sides of the groove with the groove as the central axis. By setting the limit plates, double protection can be provided, thereby effectively preventing the wheelchair from moving.

[0011] Preferably, the side wall of the limiting plate is hinged with a push-pull rod.

[0012] Preferably, one end of the push-pull rod away from the limiting plate is hinged to the side wall of the L-rod, and the limiting plate can be driven to slide by arranging the push-pull rod to cooperate with the sliding of the L-rod.

[0016] 1. The oblique-hanging lifting platform with an anti-collision structure can limit the large wheels of the wheelchair through two sets of downward-inclined support plates, so that the large wheels are stably placed inside the groove. By limiting the large wheels of the wheelchair, the lifting platform can be prevented from moving the wheelchair after being hit, which in turn causes the user's legs or body to be hit, thereby avoiding safety accidents.

[0017] 2. This obliquely hung lifting platform with an anti-collision structure has two sets of L rods that move away from each other and cooperate with the push-pull rod to make the limit plate slide upward on the inner wall of the bottom plate and protrude from the bottom plate.

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an obliquely hung lifting platform with an anti-collision structure, comprising a base plate 1 and a back plate 2, the side wall of the base plate 1 is hinged with an oblique plate 3, the inclined plate 3 can be used to push the wheelchair onto the top of the base plate 1, and the two large wheels of the wheelchair are located above the support plates 63 on the inner walls of the two groups of grooves 5, the side wall of the back plate 2 is hinged with a railing 4, a groove 5 is provided on the base plate 1, and there are two groups of grooves 5, and the inner walls of the two groups of grooves 5 are hinged with support plates 63, and a positioning mechanism 6 is provided on the base plate 1 to improve the stability of the wheelchair, and the positioning mechanism 6 can be provided to limit the large wheels of the wheelchair to prevent the lifting platform from being hit and causing the wheelchair to move, thereby avoiding the occurrence of safety accidents, and an auxiliary mechanism 7 is provided on the base plate 1, and the auxiliary mechanism 7 can provide a double protection effect for the wheelchair, which can effectively prevent the wheelchair from moving.

[0025] The above-mentioned positioning mechanism 6 includes a threaded rod 61, an L rod 62, a support plate 63, a hand wheel 64, a slider 65, a connecting rod 66, and a connecting rod 67; one end of the threaded rod 61 is rotatably connected to the inner wall of the base plate 1, and the other end of the threaded rod 61 is fixedly installed with a hand wheel 64. The outer wall of the threaded rod 61 is threadedly connected with a slider 65. By rotating the threaded rod 61 by the hand wheel 64, the slider 65 can slide up and down on the outer wall of the threaded rod 61, and the L rod 62 is slidably connected to the inner wall of the base plate 1. There are two groups of L rods 62. The two groups of L rods 62 are mirror-imaged on the inner wall of the base plate 1 with the threaded rod 61 as the central axis. The top of the L rod 62 is hinged with a connecting rod 66. The end of the connecting rod 66 away from the L rod 62 is hinged to the side wall of the slider 65. The two groups of connecting rods 66 are squeezed downward by the slider 65 so that the connecting rod 66 squeezes the L rod 62, which can The two groups of L rods 62 slide synchronously in opposite directions on the inner wall of the base plate 1 and move away from each other, and the support plate 63 is hinged to the inner wall of the groove 5. There are two groups of support plates 63, and the two groups of support plates 63 are mirror-imaged on the inner wall of the groove 5 with the threaded rod 61 as the central axis. By tilting the support plates 63 downward, the large wheels of the wheelchair can be gradually moved downward to the inside of the groove 5, and the angle between the two groups of support plates 63 can be used to limit the large wheels of the wheelchair so that the large wheels can be stably placed inside the groove 5. The bottom of the support plate 63 is hinged with a connecting rod 67, and the end of the connecting rod 67 away from the support plate 63 is hinged to the side wall of the L rod 62. When the two groups of L rods 62 move away from each other, they will pull the connecting rod 67, so that the connecting rod 67 pulls the support plate 63, causing the support plate 63 to slowly rotate toward the bottom of the groove 5.

[0026] The above-mentioned auxiliary mechanism 7 includes a limit plate 71 and a push-pull rod 72; the limit plate 71 is slidably connected to the inner wall of the base plate 1, and two groups of limit plates 71 are provided. The two groups of limit plates 71 are mirror-imaged on both sides of the groove 5 with the groove 5 as the central axis. The limit plates 71 protruding on both sides of the groove 5 can limit the large wheels of the wheelchair to prevent the large wheels of the wheelchair from sliding out of the groove 5. The side wall of the limit plate 71 is hinged with a push-pull rod 72, and the push-pull rod 72 is hinged to the side wall of the L rod 62 away from the limit plate 71. When the two groups of L rods 62 move away from each other, they will push the push-pull rod 72, so that the push-pull rod 72 pushes the limit plate 71, so that the limit plate 71 slides upward on the inner wall of the base plate 1 and protrudes from the base plate 1.

[0027] Working principle: The wheelchair can be pushed onto the top of the base plate 1 by using the inclined plate 3, and the two large wheels of the wheelchair are located above the support plates 63 on the inner walls of the two groups of grooves 5. Then, the threaded rod 61 is rotated by the handwheel 64 to make the slider 65 slide downward on the outer wall of the threaded rod 61. At this time, the slider 65 will squeeze the two groups of connecting rods 66, thereby making the connecting rod 66 squeeze the L rod 62, so that the two groups of L rods 62 slide synchronously in opposite directions on the inner wall of the base plate 1 and move away from each other. At this time, the L rod 62 will pull the connecting rod 67, thereby making the connecting rod 67 pull the support plate 63, so that the support plate 63 slowly rotates toward the bottom of the groove 5. At this time, due to the downward inclination of the support plate 63, the large wheels of the wheelchair will gradually move downward to the inside of the groove 5, and the angle between the two groups of support plates 63 can be used to limit the large wheels of the wheelchair, so that the large wheels are stably placed inside the groove 5. By limiting the large wheels of the wheelchair, it is possible to avoid The lifting platform is hit during movement, causing the wheelchair to move, which in turn causes the user's legs or body to be hit, thereby avoiding safety accidents. When the lifting platform reaches the destination, the threaded rod 61 is rotated again by the handwheel 64, so that the slider 65 moves upward on the outer wall of the threaded rod 61. At this time, the slider 65 will pull the two sets of connecting rods 66, so that the connecting rods 66 pull the L rods 62, so that the two sets of L rods 62 slide synchronously in opposite directions on the inner wall of the base plate 1 and approach each other. At the same time, the L rods 62 will squeeze the connecting rods 67, so that the connecting rods 67 squeeze the support plates 63, so that the support plates 63 gradually rotate upward on the inner wall of the groove 5 until the support plates 63 and the base plate 1 are kept horizontal. At the same time, the large wheels of the wheelchair can be lifted upward by gradually rotating the support plates 63, so that the large wheels move out of the grooves 5. At this time, the wheelchair can be pushed away, which is very convenient to use.

[0028] When the two groups of L rods 62 move away from each other, the connecting rod 67 can make the support plate 63 gradually rotate toward the bottom of the groove 5. At the same time, the L rod 62 will push the push-pull rod 72, so that the push-pull rod 72 pushes the limit plate 71, so that the limit plate 71 slides upward on the inner wall of the bottom plate 1 and protrudes from the bottom plate 1. At this time, the limit plates 71 protruding on both sides of the groove 5 can limit the large wheels of the wheelchair to prevent the large wheels of the wheelchair from sliding out of the groove 5. The use of the limit plates 71 in conjunction with the support plates 63 and the groove 5 can provide a double protection effect for the large wheels of the wheelchair, thereby effectively preventing the wheelchair from moving.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
