Description
Technical Field
The utility model relates to a parking equipment technical field specifically is a parking equipment is from locking-type anti-falling device.
Background
As the number of cars increases, parking spaces are increasingly tense, but land resources are limited, and thus mechanical parking equipment is used in large quantities. The parking equipment is the most important safety and reliability, a parking bedplate or a comb rack for bearing the weight of an automobile is mainly driven by a chain or a steel wire rope, and when the chain or the steel wire rope is broken, an anti-falling protection device is required to be added for preventing the upper-layer vehicle in a garage from falling.
The special falling protector is arranged on the parking equipment to prevent the vehicle from falling, when the vehicle is parked at the upper layer of the garage, the falling protector hook hooks the vehicle carrying disc for parking the vehicle, the falling accident caused by the breakage of the chain or the steel wire rope is effectively prevented, and the safety performance of the garage is improved. However, the existing special falling protector for the stereo garage can only play a role in preventing vehicles from falling when the garage is lifted in place and is in a static state, and the falling protector cannot effectively play a role in protection if a chain or a steel wire rope is broken in the lifting dynamic process of a garage lifting platform, so that the risk of falling accidents is increased in the operation process of the garage.
Disclosure of Invention
The utility model aims at providing a parking equipment is from locking-type anti-falling device has the garage lift platform and goes up and down also to play the effect of preventing weighing down the function among the dynamic process to have application scope extensively, simple structure, safe and reliable, advantage with low costs.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
a self-locking anti-falling device for parking equipment is characterized in that four corners of a lifting comb are respectively fixed with a vertical lifting arm, and the upper end of the lifting arm is connected with the lower end of a chain through the anti-falling device.
The anti-falling device is characterized in that a chain is fixedly connected to the upper end of a screw rod of the anti-falling device, the lower end of the screw rod sequentially penetrates through a horizontal plate with a hole, a pressure spring, a limiting plate and a plurality of nuts, the lower end of the screw rod is fixedly connected to the upper end of a rack, two sides of the rack are respectively connected with a tooth-shaped pressing block in a meshed mode, the tooth-shaped pressing block is hinged to a lifting arm, and the outer side of the tooth-shaped pressing block is a side wall of a guide rail.
The tooth-shaped pressing block is in a cam shape, and the small-diameter part of the edge of the cam is processed with a tooth shape which is meshed with the rack; the diameter of the cam edge at the large diameter part is larger than that of the cam edge: guide rail side distance-rack width.
And a sleeve is arranged on the inner ring of the pressure spring. The function of sleeve lies in: the compression spring stops after being stressed and compressed to the position of the sleeve, and the service life of the compression spring is prevented from being influenced by excessive contraction of the compression spring.
The working principle of the utility model is as follows:
when the steel wire rope or the chain is normally lifted and descended, the pressure spring is always in a contraction state under the action of pulling force received by the screw rod and the rack, and the tooth-shaped pressing block is not in contact with and rubs against the inner side of the H-shaped steel wing plate of the guide rail, so that the lifting is not hindered.
When wire rope or chain fracture, lift platform took place to fall, wire rope or chain lost the pulling force, and lifting screw and rack pushed tooth type briquetting rotatory in the twinkling of an eye under the effect of spring, because tooth type briquetting is the cam structure, and the protruding department of tooth type briquetting and the inboard friction that produces of guide rail H shaped steel pterygoid lamina, and bigger play the auto-lock effect, finally play the function that prevents lift platform's the falling.
Furthermore, a friction block or a friction structure for increasing friction force can be arranged at the protruding part of the tooth-shaped pressing block and the inner side of the H-shaped steel wing plate, so that the locking effect is improved.
The utility model has the advantages that:
1. the utility model discloses have garage lift platform lift dynamic in-process and also can play the effect of preventing weighing down the function, greatly increased sky parking equipment's safe operation, especially for dangerous stage at lift platform dynamic in-process, can make to this process and prevent weighing down the safety guarantee and have important meaning to sky parking equipment.
2. The utility model discloses application scope is extensive, is not limited to platen formula parking equipment, and perhaps comb-tooth formula parking equipment is all applicable, no matter hoisting device chain or wire rope all can with the utility model discloses the device is connected.
3. The utility model discloses simple structure, safe and reliable, with low costs, easily preparation and maintenance.
