Detailed Description

In order to make the purpose and technical solution of the present invention clearer, the present invention is further described with reference to the accompanying drawings and embodiments:

as shown in fig. 1 to 3, the multipurpose high-efficiency air door for the main roadway comprises: the support 1 is fixed on the ground and a wall body, and the support 1 comprises an upper support 11 and a side support 12; a through groove is formed in the front frame 111 of the upper support 11, and a chain 2 is arranged in the through groove; the power device 3 is arranged at the upper end of the bracket 1; the transmission case 4 is mounted at the upper end of the bracket 1, is connected with the power device 3, and drives the chain 2 to run through a gear structure (not shown in the figure, and the gear and chain connecting structure is in a conventional design); the transmission case 4 comprises an electromagnetic clutch (not shown in the figure); the door leaf 5 is movably arranged on the upper bracket 11 through a connecting sleeve 6;

a connecting piece 61, a pulley block 62 and an outer sleeve 63 are arranged in the connecting sleeve 6, and the connecting piece 61 is connected and fixed with the door leaf 5 and the chain 2; the pulley block 62 is arranged between the connecting sleeve 6 and the upper bracket 11, and the connecting sheet 61 and the pulley block 63 are fixedly wrapped by the outer sleeve 63; the two sides of the through groove of the upper bracket form a track of the pulley block; the outer sleeve 63 is fixedly connected with the connecting piece 61 through welding or bolts, and the outer sleeve 63 is fixedly connected with the pulley block 62 through bolts; a controller (not shown) for controlling the operation of the power plant.

Preferably, the door leaf 5 is further provided with a pedestrian door 7; the pedestrian door 7 is translated through a side shifting device; a connecting device is arranged between the pedestrian door 7 and the door leaf 5; the door leaf 5 is provided with a cavity for accommodating a pedestrian door 7 during lateral movement; the sliding rail 51 is arranged at the position, above the pedestrian door, of the door leaf 5, the upper portion of the pedestrian door 7 is fixed through a pulley 71, and the pulley 71 runs on the sliding rail 51.

Preferably, the door leaf 5 is provided with slideways 52 at the upper and lower parts of the pedestrian door 7; the pedestrian door 7 is provided with a plurality of flat wheels 72, and the flat wheels 72 run on the slide ways 52.

Preferably, the switching device is a rotary door handle lock (not shown in the figures).

Preferably, the rear frame 112 of the upper bracket is further provided with a sliding groove, a plurality of sliding blocks 53 are arranged in the sliding groove, each sliding block is fixedly connected with a supporting frame 54, and the other end of each supporting frame 54 is fixed at the middle position of the door leaf 5 in the vertical direction.

Preferably, a plurality of reinforcing ribs 55 are arranged on the door leaf 5.

Preferably, the power device is an explosion-proof motor.

Preferably, the controller is a PLC controller.

Preferably, two fore-stock 121 of collateral branch frame are vertical to be placed conveniently and fixed with the wall body, and the fore-stock directly is equipped with a plurality of link with the after-poppet, and two after-poppet 122 set up backward for the support is right trapezoid when the side is seen, and this design makes the support take up an area of more extensively, and the installation is more steady, provides better holding power for the door leaf.

Two sides of the traditional air door are opened and closed, and the folded cable and the water pipe are arranged in a winding way; the design of the invention is as shown in fig. 2, the air doors of the cable through hole 81 and the water pipe through hole 82 are not required to be opened or closed, so that the cables, the water pipes and other equipment are not required to be arranged by bypassing.

The installation mode of the invention is as follows: firstly, mounting and fixing a bracket on the ground and a wall body; secondly, mounting a motor, a transmission case and a gear chain structure, and mounting a connecting device; thirdly, fixedly installing the door leaf provided with the pedestrian door on the connecting piece of the connecting device; welding one end of each support frame on the door leaf, and welding the other end of each support frame on the corresponding sliding block.

The use process of the invention is as follows: the control motor drives the chain and rotates, drives the door leaf simultaneously and opens, and when closing the door, the action of closing the door can be accomplished in the control motor reversal, when having the pedestrian to pass, only needs the rotatory door handle, opens and can pass. When the power is cut off, the pedestrian door is not influenced because of the manual mechanical opening mode, and the door leaf is separated from the motor when the power is cut off because the electromagnetic clutch is arranged in the transmission case, so that the push-pull door leaf cannot be blocked by the motor, and the manual opening and closing are easy to carry out.

The design principle of the invention is as follows: the connecting sleeve is designed to ensure that the weight of the door leaf is borne by the bracket through the pulley block, the pulley block is used for reducing the friction force of opening and closing movement and facilitating opening and closing, and in addition, the chain is only responsible for opening and closing the door leaf left and right and does not bear the weight of the door leaf, so that the door leaf is more durable; the design of the supporting frame enables the upper part and the middle part of the door leaf to be fixed, and compared with the traditional method that the door leaf is fixed only at the upper part, the door leaf cannot be shaken by wind; thirdly, the electromagnetic clutch is arranged, and the door leaf can be manually opened and closed when power is cut off; and fourthly, the flat wheel design at the pedestrian door is adopted, so that the problem of labor waste caused by wind resistance during opening is avoided.
