Unpowered release hook for machinery multistory parking facility

Abstract

The invention relates to an unpowered safe hook for a mechanical three-dimensional parking device, belonging to the field of mechanical parking device technology. According to the technical scheme of the invention, one side of the hook is provided with a connecting seat, the middle part of an operating rod is hinged on the connecting seat by a pin roll, the left end of the operating rod is equipped with a sliding chute, in normal operation, the right end of the operating rod shifts on the connecting seat upwards and downwards relative to a guiding plate, is slidably contacted with a working inclined plane on the hook, the hook is pushed from the connecting seat; the connecting seat is equipped with a pull rod which can shift upwards and downward relative to the connecting seat but not rotate, the pull rod is provided with a guide pin, the end part of which locates in the sliding chute on the operating rod; a spring is arranged on the pull rod, when an abnormal situation occurs, the pull rod shifts downward under the action of the spring, the operating rod is driven by the guiding pin to rotate around the pin roll thereof, so that the right end of the operating rod is separated from the hook. The safe property of the hook is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a non-powered safety hook used on mechanical three-dimensional parking equipment, in particular to a mechanical safety hook without a power device to replace the current electromagnetic and electric safety hooks. It belongs to the technical field of mechanical parking equipment. Background technique [0002] In recent years, the domestic mechanical parking equipment industry has developed rapidly. There are about 40,000 parking spaces for lifting and traversing mechanical parking equipment put into use every year. There are nearly 500,000 parking spaces in this type of parking equipment in operation across the country. According to Article 4.6.2.10 of "GB17907-1999 General Safety Requirements for Mechanical Parking Equipment": "After the vehicle-carrying board moves to the parking space, in order to prevent the car-carrying board from falling suddenly for some reason, an anti-falling device should be installed." Therefore, t...

Problems solved by technology

At this time, the vehicle loading plate is seriously tilted. If the on-site operators do not pay attention, it will cause the vehicle to roll over.

Since then, although many manufacturers have added the "hook open" signal point in the control system, so that when the hook is not fully opened, the strong current system cannot operate the descending action

However, due to the reasons of signal components and signal transmission itself, such accidents still continue to occur

And increasing the control point will increase the cost and complicate the system, but will increase the failure probability of the whole system
