Abstract
Description
Technical Field
[0001] This utility model relates to an anti-fall mechanism for a vehicle transport loading platform, belonging to the field of vehicle transport technology. Background Technology
[0002] Currently, most vehicle transport vehicles in China do not have anti-fall protection on their upper cargo platforms. The upper cargo platform is generally raised and lowered using a steel wire rope pulley system with hydraulic cylinders. If the hydraulic pipe bursts or the steel wire rope breaks during the platform's raising and lowering process, the upper platform will fall directly, causing serious damage to the vehicles and even resulting in injury or death to the personnel operating on the lower level, leading to a serious safety accident. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a fall prevention mechanism for a vehicle transport loading platform that is in contrast to the above-mentioned prior art. The fall prevention mechanism will not be triggered when the entire vehicle is lifted or lowered. Once the steel wire rope breaks, the fall prevention mechanism will work to lock the platform and prevent it from falling, thus preventing safety accidents caused by the loading platform falling.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a fall prevention mechanism for a vehicle transport loading platform, comprising a column, a vertically formed groove, a slider disposed within the groove, a ratchet mounting hole on the slider, a fall prevention ratchet disposed within the ratchet mounting hole, the fall prevention ratchet being rotatably connected to the slider via a fall prevention ratchet fixing pin, a torsion spring disposed between the fall prevention ratchet and the fall prevention ratchet fixing pin, a waist-shaped hole above the ratchet mounting hole, a slider lifting pin disposed within the waist-shaped hole, a lifting wire rope casting head disposed on the slider lifting pin, and the slider lifting pin being connected to the fall prevention ratchet via an adjusting rod.
[0005] Optionally, a fall-prevention rack is provided vertically along the inner edge of the groove, and the fall-prevention ratchet cooperates with the fall-prevention rack.
[0006] Optionally, the slider has a clearance groove on the side corresponding to the anti-fall rack, and the anti-fall rack is disposed in the clearance groove.
[0007] Optionally, spring retaining rings are provided at both ends of the anti-fall ratchet fixing pin.
[0008] Optionally, a platform support pin is provided below the ratchet mounting hole, and a loading platform is provided on the platform support pin.
[0009] Optionally, a fixed wire rope pulley is provided above the slider, a lifting cylinder is provided on one side of the slide groove, a movable wire rope pulley is provided at the lower end of the lifting cylinder, a buckle is provided above the movable wire rope pulley, and a lifting wire rope is provided between the buckle and the lifting wire rope pouring head. The lifting wire rope is sequentially wound around the movable wire rope pulley and the fixed wire rope pulley.
[0010] Compared with the prior art, the advantages of this utility model are:
[0011] This utility model discloses an anti-fall mechanism for a vehicle transport loading platform. The anti-fall mechanism will not be triggered when the entire vehicle is raised or lowered. Once the steel wire rope breaks, the anti-fall mechanism will work to lock the platform and prevent it from falling, thus preventing safety accidents caused by the loading platform falling.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0018] See Figures 1-4This utility model relates to an anti-fall mechanism for a vehicle transport loading platform. It includes a column 1, a vertical groove 2, a slider 3, a ratchet mounting hole 4, an anti-fall ratchet 5, and an anti-fall ratchet 5 rotatably connected to the slider 3 via an anti-fall ratchet fixing pin 6. A torsion spring 7 is provided between the anti-fall ratchet 5 and the anti-fall ratchet fixing pin 6. An oblong hole is provided above the ratchet mounting hole 4, and a slider lifting pin 8 is provided in the oblong hole. A lifting wire rope casting head 9 is provided on the slider lifting pin 8. The slider lifting pin 8 and the anti-fall ratchet 5 are connected by an adjusting rod 10.
[0019] A fall-prevention rack 11 is vertically arranged inside the slide groove 2, and the fall-prevention ratchet 5 cooperates with the fall-prevention rack 11;
[0020] The slider 3 has a clearance groove 12 on the side corresponding to the anti-fall rack 11, and the anti-fall rack 11 is disposed in the clearance groove 12;
[0021] The anti-fall ratchet fixing pin 6 is provided with spring retaining rings 13 at both ends;
[0022] A platform support pin 14 is provided below the ratchet mounting hole 4, and a loading platform 15 is provided on the platform support pin 14;
[0023] A fixed wire rope pulley 16 is provided above the slider 3, and a lifting cylinder 17 is provided on one side of the slide chute 2. A movable wire rope pulley 18 is provided at the lower end of the lifting cylinder 17, and a buckle 19 is provided above the movable wire rope pulley 18. A lifting wire rope 20 is provided between the buckle 19 and the lifting wire rope pouring head 9. The lifting wire rope 20 is sequentially wound around the movable wire rope pulley 18 and the fixed wire rope pulley 16.
[0024] Working principle:
[0025] During the lifting and lowering of the loading platform, the piston rod of the hydraulic cylinder actuates, driving the lifting wire rope casting head 9 up and down via the wire rope pulley mechanism. The lifting wire rope casting head 9 then drives the slider lifting pin 8 to rise along the oblong hole on the slider 3. The slider lifting pin 8, through the adjusting rod 6, drives the anti-fall ratchet 5 and the torsion spring 7 to rotate upward around the anti-fall ratchet fixing pin 2. After the anti-fall ratchet 5 unlocks from the anti-fall rack 11, when the slider lifting pin 8 reaches the uppermost oblong hole on the slider 3, the lifting wire rope casting head 9 pulls the slider lifting pin 8, causing the entire anti-fall slider to move up and down, thus achieving the lifting and lowering of the loading platform. If the wire rope breaks during the lifting process, the torsion spring 7 will quickly drive the anti-fall ratchet 5 to rotate downward around the anti-fall ratchet fixing pin 2 until the anti-fall ratchet 5 locks the anti-fall rack 11, achieving self-locking of the slider and ultimately preventing the platform from falling.
[0026] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
