Abstract
The utility model relates to the technical field of double-doors, in particular to a double-door opening structure of a construction hoist. The double-door opening structure of the construction hoist comprises an upper double-door, a lower double-door, a pulley installed on the top of the construction hoist, and a double-door frame. The double-door frame is a frame composed of two vertical rods. The two vertical rods of the double-door frame are fixedly connected with the construction hoist. An upper door wheel frame is fixedly connected with the bottom of the upper double-door. A lower door wheel frame is fixedly connected with the top of the lower double-door. The upper double-door is connected with the two vertical rods of the double-door frame in a sliding mode through the upper door wheel frame. The lower double-door is connected with the two vertical rods of the double-door frame in the sliding mode through the lower door wheel frame. The upper door wheel frame is connected with the lower door wheel frame through a steel wire rope which is installed on the pulley in a supporting mode. The double-door opening structure of the construction hoist has the advantages of being smooth in opening and closing and high in security assurance.
Description
Technical field
The utility model relates to the building hoist technical field, relates in particular to a kind of building hoist double door opening structure.
Background technology
In engineering construction, along with popularizing gradually of mechanization, building hoist has also occupied irreplaceable status in this field, and till now, the technology of building hoist is moving to maturity gradually also.Wherein, take double door as example, double door link plate and lower double door link plate are realized opening and closing by steel rope on the prior art.Because opening or closing difficult just by the steel wire suspension strut, therefore often appears in double door.
The utility model content
The purpose of this utility model is to provide easily building hoist double door opening structure of a kind of simple in structure, switch gate.
In order to achieve the above object, the utility model is achieved in that
A kind of building hoist double door opening structure, comprise double door and lower double door, be installed on the pulley at the top of building hoist, also comprise the double door framework, the framework of described double door framework for being consisted of by two montants, two montants of described double door framework are fixedly connected on the building hoist; The below of described upper double door is fixedly connected with the trolley frame; The top of described lower double door is fixedly connected with lower trolley frame; Described upper double door is by two montant sliding block joints of described upper trolley frame and described double door framework; Described lower double door is by two montant sliding block joints of described lower trolley frame and described double door framework; Described upper trolley frame is connected by steel rope with described lower trolley frame, and described steel rope supports and is installed on the described pulley.
As a kind of improvement, on two montants of described double door framework chute is arranged, the two ends of described upper trolley frame are provided with the slide block I supporting with described chute; The two ends of described lower trolley frame are provided with the slide block II supporting with described chute.
As a kind of improvement, in the slide block I at the two ends of described upper trolley frame roller is housed; In the slide block II at the two ends of described lower trolley frame roller is housed.
The beneficial effects of the utility model have: double door opens and closes smooth, and safety control is high.

The specific embodiment
A kind of building hoist double door opening structure, comprise double door 1 and lower double door 2, be installed on the pulley at the top of building hoist, also comprise double door framework 3, the framework of described double door framework 3 for being consisted of by two montants, two montants of described double door framework 3 are fixedly connected on the building hoist; The below of described upper double door 1 is fixedly connected with trolley frame 4; The top of described lower double door 2 is fixedly connected with lower trolley frame 5; Described upper double door 1 is by the two piece montant sliding block joints of described upper trolley frame 4 with described double door framework 3; Described lower double door 2 is by the two piece montant sliding block joints of described lower trolley frame 5 with described double door framework 3; Described upper trolley frame 4 and described lower trolley frame 5 are connected by steel rope, and described steel rope supports and is installed on the described pulley.
Wherein, on two montants of described double door framework 3 chute 31 is arranged, the two ends of described upper trolley frame 4 are provided with the slide block I 6 supporting with described chute 31; The two ends of described lower trolley frame 5 are provided with the slide block II 7 supporting with described chute 31.
Wherein, in the slide block I 6 at the two ends of described upper trolley frame 4 roller is housed; In the slide block II 7 at the two ends of described lower trolley frame 5 roller is housed.
When needing to open, lower double door is pushed away downwards, and lower trolley frame is fixed on the lower double door, therefore also follows it to move downward together; Simultaneously, take turns to the doorstep the frame upward movement by the steel rope drive, and upper trolley frame is fixed in double door, therefore drives upper double door and upwardly open.
In like manner, in the time of need to closing, lower double door is upwards drawn, double door moves downward in the drive, and final, double door is closed.
Above content is the further description of this practicality being done in conjunction with concrete preferred implementation, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
