Technical Field

The invention relates to the field of building construction, in particular to a construction channel opening and closing device.

Background

In a building construction site, vehicle access control is an important means for vehicle management, does not aim at collecting parking fees, and mainly manages vehicle access authority. The access control equipment in the prior art mainly includes two types, one type is used for a long time, such as the access control equipment of an office building, and the other type is used for a temporary time, such as the access control equipment used in construction projects. The door control equipment used for a long time cannot be dismantled once being built and can be used all the time, the door control equipment used temporarily is usually built temporarily after a project is started, and all door control facilities are dismantled after the project is completed. For the temporarily used access control equipment, the process of civil engineering, wiring debugging and the like needs to be carried out, so that the construction time is longer, and the progress of the whole project is influenced. In the use process, if the position of the access opening needs to be adjusted, the access opening needs to be rebuilt. In addition, after the project construction is completed, all entrance guard facilities need to be dismantled, and the entrance guard hardware is easy to damage and cannot be reused.

Disclosure of Invention

The invention aims to provide a construction passage opening and closing device, which improves the reuse rate of an access control system and reduces the cost of engineering management.

The purpose of the invention is realized by the following technical scheme:

a construction channel opening and closing device comprises an upright post and baffles symmetrically arranged on two sides of the upright post, wherein the upright post and the two baffles are fixed on the ground through bolts, a movable cavity is formed in the middle of the upright post, a motor is installed in the upright post, the output end of the motor is connected with a rotating shaft, the rotating shaft can freely rotate in the movable cavity, rectangular holes communicated with the movable cavity are formed in two sides of the upright post, two fence bodies are sleeved on the rotating shaft, the fence bodies penetrate through the rectangular holes to seal a gap between the upright post and the baffles, a driving block is fixedly installed on the rotating shaft, and the positions of the driving block and the fence bodies are configured to be respectively contacted with the two fence bodies when the rotating shaft rotates in the positive and negative directions; still including setting up first district and the second district of punching the card on the stand outer wall, first district and the second of punching the card is connected with the motor through the controller, installs the limiting plate on the stand, installs the spring in the both sides of limiting plate, and when the fence body was opened completely, the outer wall and the spring contact of the fence body. When the barrier is in work, the upright post and the two baffles are respectively fixed on the ground at the inlet and the outlet and can be fixed by screws, when a person passing in and out of a building site swipes a card in a first card swiping area for verification, the first card swiping area is an inlet verification area, after the identity verification of the person entering the barrier is qualified, the controller controls the motor to rotate anticlockwise, the driving block fixed on the rotating shaft rotates reversely along with the rotating shaft until the driving block is contacted with the outer wall of the barrier body, and the driving block drives the barrier body to rotate freely in the movable cavity and the rectangular hole until the barrier body between the baffles and the upright post is completely opened; when a person goes out from a construction site, the card is held in a second card swiping area for identity verification, after the identity verification of the person who goes out is qualified, the controller controls the motor to rotate clockwise, the driving block fixed on the rotating shaft rotates positively along with the rotating shaft until the driving block is contacted with the outer wall of the other fence body, the driving block drives the fence bodies to rotate freely in the movable cavity and the rectangular hole until the fence bodies between the baffle and the stand column are completely opened, so that free entering and exiting in the construction site can be realized, after the person finishes entering and exiting, the motor stops moving, and meanwhile, the fence bodies are contacted with the springs on the limiting plate and are compressed; the door control system is simple in structure, can be conveniently and quickly mounted and dismounted by adopting bolt fixing mode, can be used for being continuously used on another construction site after being dismounted after one construction site is completed, improves the reuse rate of the door control system, and reduces the cost of engineering management.

The central angle corresponding to the rectangular hole is 100-130 degrees. The rectangular hole is communicated with the movable cavity, so that the fence body can freely rotate in a certain range around the rotating shaft, the central angle corresponding to the rectangular hole is in the range of 100-130 degrees, 90-degree complete opening and closing of the fence body are guaranteed, meanwhile, a certain space is reserved for the fence body, the situation that a connecting part between the fence body and the rotating shaft is damaged due to direct rigid friction between the fence body and the rotating shaft is avoided, and the service life of the invention is further prolonged.

The spring is a torsion spring. The fence body is in contact with the spring on the limiting plate after being completely opened, and after the motor stops outputting power, the kinetic energy carried by the fence body is gradually reduced and irregularly changed, namely the impact force of the fence body on the upright post is greatly changed and inconsistent in direction, the elastic strength of the torsion spring in each direction is high, the damage degree of the torsion spring is low when the impact of the fence body is buffered, the high service life of each structural component of the invention can be ensured when the fence body is continuously opened and closed, and the practicability of the invention is improved.

Compared with the prior art, the invention has the following advantages and beneficial effects:

1. according to the invention, after people finish entering and exiting, the motor stops moving, meanwhile, the fence body is contacted with the spring on the limiting plate and compressed, and due to the lack of continuous power output of the motor, the elastic force generated by the compressed spring in a recovery deformation mode pushes the fence body back, so that the fence body recovers the original shape, the gap between the upright post and the baffle is sealed again, and the entrance and the exit of a construction site are ensured to be in a limited state; the door control system is fixed by bolts, so that the door control system can be conveniently and quickly mounted and dismounted, and can be used for continuous use on another construction site after being dismounted after one construction site is completed, the reuse rate of the door control system is improved, and the cost of engineering management is reduced;

2. the central angle corresponding to the rectangular hole is within the range of 100-130 degrees, a certain space is reserved for the fence body while the fence body is completely opened and closed at 90 degrees, the damage of a connecting part between the fence body and the rotating shaft due to the direct generation of hard friction between the fence body and the rotating shaft is avoided, and the service life of the invention is further prolonged;

3. the torsion spring has higher elastic strength in all directions, the self damage degree is low when the impact of the fence body is buffered, the higher service life of each structural part can be ensured when the fence body is continuously opened and closed, and the practicability of the invention is improved.
