Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
As shown in fig. 1-5, a lifting special factory mechanical safety protection door is arranged at a position right below a special factory workshop door and comprises a sealing shell 1, a lifting door 2, a transmission mechanism 3, a transmission gear set 4 and a driving piece 5.
The sealed housing 1 is taken as an accommodating space of the lifting door 2, the shape of the sealed housing is rectangular, the lifting door 2 is positioned in the sealed housing 1, and an outlet for the lifting door 2 to enter and exit is arranged at the top end of the sealed housing 1.
The driving member 5 is located as a lifting driving force of the lifting door 2 in the accommodating space beside the hermetic case 1, and its output end is disposed along the height direction of the lifting door 2.
The transmission gear set 4 is a bevel gear set, and the bevel gear set comprises two bevel gears, wherein one bevel gear is connected with the output end of the driving piece 5 in a transmission way, and the other bevel gear is connected with the transmission mechanism 3.
The transmission mechanism 3 comprises a transmission rod 31, transmission gears 32 and transmission racks 33, one end of the transmission rod 31 is connected to another bevel gear in a transmission way, the other end of the transmission rod 31 is movably connected to the sealed shell 1, the transmission rod 31 is uniformly and coaxially fixedly connected with a plurality of transmission gears 32 along the length direction of the transmission rod, preferably, as shown in fig. 1, the transmission gears 32 are five, each transmission gear 32 is in meshed connection with one transmission rack 33, the transmission racks 33 are arranged along the height direction of the lifting door 2, and the top end of each transmission rack 33 is connected to the lifting door 2.
The maximum lifting height of the lifting door 2 corresponds to the maximum driving height of the driving rack 33.
Wherein, the driving piece 5 can adopt a hand wheel. The purpose of starting the driving member 5 can be achieved by manually turning the hand wheel. In another possible embodiment, the driving member 5 may also use a driving motor, which is started to achieve the purpose of automatic driving.
When the safety door works, the driving piece 5 is started to drive one bevel gear to rotate, the other bevel gear rotates under the rotation action of the bevel gear set, meanwhile, the transmission rod 31 and the transmission gear 32 are driven to rotate, and as the transmission gear 32 is meshed with the transmission rack 33, the transmission rack ascends and descends along with the rotation of the transmission gear 32, and finally, the lifting door 2 is driven to realize ascending and descending, so that the safety door function is realized.
Meanwhile, the lifting door 2 is set as a lifting rubber door, and when the lifting door 2 is lifted to the bottom end of a workshop door of a special factory to be abutted, the lifting rubber door plays a role of a waterproof gate under the sealing effect of rubber materials.
The lifting rubber door top is provided with an arc-shaped structure, and the arc-shaped structure can provide better deformation capability when being abutted against the workshop door, so that the sealing performance between the lifting rubber door and the workshop door is improved, and the waterproof performance is improved.
And sealing rubber strips are arranged on two sides close to the top end of the lifting rubber door. The sealing rubber strip can realize the function of further sealing.
In addition, as the supporting force of the lifting door 2 only comes from the connecting acting force of the bottom end and the transmission rack 33 after the lifting door 2 is lifted, the two side ends of the lifting door 2 have no supporting force, and in order to avoid the problem of poor stability of the lifting door 2 caused by the fact that the two side ends have no supporting force after the lifting door 2 is lifted, the two sides of the lifting door 2, which are close to the top, are connected with the flexible rigid ropes 6, and the other ends of the flexible rigid ropes 6 extend into the sealed shell 1 and are connected with the telescopic springs 7 after passing through the fixed pulleys; and the sum of the maximum amount of expansion of the expansion spring 7 and the length of the flexible rigid rope 6 corresponds to the maximum lifting height of the lifting door 2. Thus, as the lifting door 2 is lifted, the flexible rigid rope 6 is gradually pulled, after the lifting door 2 is lifted to a certain height, the flexible rigid rope 6 is completely straightened, then as the lifting door 2 is lifted, the telescopic springs 7 are pulled, the sum of the maximum telescopic amount of the telescopic springs 7 and the length of the flexible rigid rope 6 corresponds to the maximum lifting height of the lifting door 2, and the purpose is to match the height of the lifting door 2, so that after the lifting door 2 is lifted to the required height, the stabilizing effect on the two side ends of the lifting door 2 is realized under the combined supporting effect of the flexible rigid rope 6 and the telescopic springs 7.
The flexible rigid cord 6 may be made of any one of nylon, flexible plastic, and flexible metal such as copper alloy.
Furthermore, a connecting base 9 is arranged between the lifting door 2 and the transmission rack 33, supporting seats 10 are arranged on two sides of the connecting base 9, and the supporting seats 10 are in rolling connection with the inner wall of the sealed shell 1 through rollers 11. Thus, when the lifting door 2 is lifted, the connecting base 9 is lifted along with the lifting, and the roller 11 rolls on the inner wall of the sealed shell 1 in the lifting process of the connecting base 9, so that the lifting door 2 can be supported.
And two inner sides of the outlet of the sealing shell 1 are provided with rolling shafts 8, one end of the inner wall of the sealing shell 1 connected with the rolling shafts 8 is obliquely downwards arranged, the two rolling shafts 8 are oppositely arranged, and the distance between the two rolling shafts 8 is the same as the thickness of the lifting rubber door, so that the two rolling shafts 8 are in contact with the lifting rubber door. Thus, the two rollers 8 can play a supporting and guiding role in the lifting process of the lifting door 2.
The whole liftable special factory mechanical safety protection door not only can realize the sealing and waterproof effect on the special factory workshop door through lifting, but also is provided with a structure with a stable function at each part of the lifting door 2, so that the lifting stability of the lifting door 2 is high, and the function of the waterproof gate with high stability is comprehensively realized.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model.
