The principle of the utility model is as follows: under a normal state, the touch rod pulls one end of the connecting rod by means of self gravity, the connecting rod rotates anticlockwise around the rotating shaft, the other end of the connecting rod is made to be in contact with the limiting block above, and the connecting rod cannot trigger the limiting block below; when the automatic door moves downwards, the touch rod meets an obstacle, the touch rod is jacked up, the touch rod drives one end of the connecting rod to move upwards, the connecting rod rotates clockwise around the rotating shaft, the other end of the connecting rod touches the stopper below the connecting rod to enable the stopper to trigger power-off, and the automatic door stops, so that the safety of the automatic door is improved.
Description
Technical Field
The utility model relates to a construction elevator, in particular to an anti-pressure device for an automatic door of the construction elevator.
Background
Along with the improvement of the automation degree of the construction elevator, the construction efficiency is improved, but the automatic operation also brings about a plurality of potential safety hazards, if people are pressed in the descending process of the automatic door, if the automatic door cannot be stopped in time, casualties can be possibly caused, and therefore, the improvement of the safety of the automatic door is very necessary.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the pressure-proof device for the automatic door of the construction elevator, which realizes the function of automatically stopping when an obstacle is encountered in the descending process of the automatic door and improves the safety of the automatic door.
In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a construction elevator automatically-controlled door pressure-resistant device, is including establishing the pole that bumps in the automatically-controlled door below, rotating through the pivot and installing at the connecting rod of automatically-controlled door lower part, establishing the stopper in connecting rod one end top, establishing the stopper in connecting rod one end below and establishing the engaging lug on bumping the pole, the other end and the engaging lug of connecting rod are articulated. The principle of the utility model is as follows: under a normal state, the touch rod pulls one end of the connecting rod by means of self gravity, the connecting rod rotates anticlockwise around the rotating shaft, the other end of the connecting rod is made to be in contact with the limiting block above, and the connecting rod cannot trigger the limiting block below; when the automatic door moves downwards, the touch rod meets an obstacle, the touch rod is jacked up, the touch rod drives one end of the connecting rod to move upwards, the connecting rod rotates clockwise around the rotating shaft, the other end of the connecting rod touches the stopper below the connecting rod to enable the stopper to trigger power-off, and the automatic door stops, so that the safety of the automatic door is improved.
As an improvement, supporting legs are arranged on two sides of the lower end of the automatic door, the two supporting legs support to form a mounting hole space, the collision rod is arranged in the mounting space, and the bottoms of the supporting legs are lower than the bottom of the collision rod.
As an improvement, the limiting block, the connecting rod and the limiting device are arranged on a handle groove of the automatic door.
Compared with the prior art, the utility model has the following beneficial effects:
when the automatic door moves downwards, the touch rod meets an obstacle, the touch rod is jacked up, the touch rod drives one end of the connecting rod to move upwards, the connecting rod rotates clockwise around the rotating shaft, the other end of the connecting rod touches the stopper below the connecting rod to enable the stopper to trigger power-off, and the automatic door stops, so that the safety of the automatic door is improved.

Fig. 2 is an enlarged view of fig. 1 at a.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the pressure-proof device for the automatic door of the construction elevator comprises a collision rod 2 arranged below an automatic door 1 and more than two limit mechanisms associated with the collision rod 2, wherein the two limit mechanisms are arranged in the embodiment and can ensure that the collision rod 2 is kept horizontal; the limiting mechanism comprises a connecting rod 4 which is rotatably arranged at the lower part of the automatic door 1 through a rotating shaft 5, a limiting block 6 arranged above one end of the connecting rod 4, a limiting device 7 arranged below one end of the connecting rod 4 and a connecting lug 3 arranged on the touch rod 2, the connecting lug 3 is welded on the touch rod 2, and the other end of the connecting rod 4 is hinged with the connecting lug 3 through a pin shaft; the limiting block 6, the connecting rod 4 and the limiting device 7 are installed on a handle groove of the automatic door 1, a bending plate bent by 90 degrees is arranged at the lower end of the automatic door 1, the touch rod 2 is arranged below the bending plate, the touch rod 2 is parallel to the bending plate, a avoidance hole is formed in the bending plate corresponding to the connecting lug 3, and the touch rod 2 can move up and down through a linkage mechanism formed by the touch rod 2, the connecting lug 3 and the connecting rod 4; under a normal state, the connecting rod 4 has a tendency of anticlockwise rotating and extrudes the limiting block 6 above, and the connecting rod 4 can rotate clockwise only when the touch rod 2 meets an obstacle; the lower extreme both sides of automatically-controlled door 1 are equipped with the supporting legs, and two supporting legs support and form the mounting hole space, touch pole 2 and establish in installation space, the bottom of supporting legs is less than the bottom of touching pole 2, and under the normal condition, automatically-controlled door 1 is down after to the end, and the supporting legs pastes the ground, touches pole 2 and can not meet the hindrance.
The principle of the utility model is as follows: under a normal state, the touch rod 2 pulls one end of the connecting rod 4 by means of self gravity, the connecting rod 4 rotates anticlockwise around the rotating shaft, the other end of the connecting rod 4 is made to be in contact with the limiting block 6 above, and the connecting rod 4 cannot trigger the limiting block 7 below; when the automatic door 1 descends, the collision rod 2 is jacked up when encountering an obstacle, the collision rod 2 drives one end of the connecting rod 4 to move upwards, the connecting rod 4 rotates clockwise around the rotating shaft, the other end of the connecting rod 4 touches the lower limit stop 7 to trigger the power-off, and the automatic door 1 stops, so that the safety of the automatic door 1 is improved.
