Description

Buffer structure of construction elevator flap gate

Technical Field

The utility model relates to a construction elevator specifically is a buffer structure of construction elevator flap gate.

Background

Traditional construction elevator turns over the board door and is two parts from top to bottom, turns over the board door through the push-and-pull during the business turn over material and realizes, and some turn over board door push-and-pulls are hard, and the workman often demolishs the threshold on the project, causes construction elevator also can operate under the condition that the door was opened, and this it is really to have huge hidden danger, causes the accident very easily. In order to solve the problems, the prior art designs a novel flap gate, the device is a whole, and the flap gate is rotated by 90 degrees and put up in a building by a motor driving chain or a steel wire rope. The turnover door is controlled to be opened and closed electrically, so that the labor is saved, and the turnover door is safe and reliable; meanwhile, the channel built by the wall attaching frame is saved. Therefore, the project cost can be reduced, but the stress of the flap door is uneven when the flap door is opened and closed, so that the arrangement of the steel wire ropes is disordered.

A material conveying and people entering and exiting channel is arranged between the construction elevator and the floor, and a floor access door is required to be arranged at the joint of the access opening and the construction elevator. The height of the floor access door is not lower than 1.8m, and the lower edge of the door is away from the access surface and is not more than 50 mm. The flap gate is in a normally closed state when the cage moves up and down, and can be opened by personnel in the cage only when the cage stops.

In order to solve the impact effect of the flap door in the lower process. Solutions are also provided in the prior art, such as: no. CN 102874673B a construction elevator cage panel turnover door buffer, this buffer includes panel turnover door buffer and buffer board, panel turnover door buffer comprises buffer beam, buffer head, round pin axle, buffer spring, angle stopper and regulating lever seat, the buffer beam bottom is provided with deep floor, it has the spliced pole to weld on the buffer beam between the deep floor, the pole is adjusted to buffer beam port middle part being equipped with, buffer spring is equipped with between regulation pole and the spliced pole. The use of a buffer spring to prevent the flap door from closing too quickly is mentioned. Through the full text understanding, this buffer spring only can play a role when closing to the flap gate, and in the actual production, the flap gate directly overlaps with building or scaffold frame after overturning downwards, in a twinkling of an eye of handing-over, also can produce great impact force, directly leads to the deformation damage of flap gate.

The authorization notice number CN 210029681U describes a construction elevator cage flap door buffer, and in the scheme, the arrangement of a buffer cushion and two buffer springs on the outer side of the upper part of the flap door is pointed out so as to relieve the impact force when the flap door falls to the ground. But this technical scheme structure is complicated, loaded down with trivial details, especially the blotter protrusion outside the flap gate, seriously influences the operation safety of cage, is not conform to the engineering standard, and also can correspond behind the flap gate upset be the scaffold frame, does not have the stationary plane as the support, and its blotter can't play a role.
