All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or device.
As shown in fig. 1-2, a cover plate safety detection device for an escalator or a moving walk according to the present embodiment includes a support plate 3 fixed on angle steel 12, a safety switch 4 and a first positioning plate 1 fixed on the support plate 3, a vertical rod 7 movably penetrating through the first positioning plate 1, and a second positioning plate 2 fixed on the vertical rod 7 and mutually matched with the safety switch 4.
The upright rod 7 is movably connected to the first positioning plate 1 through an elastic piece 5, and a limiting piece 6 is arranged above the elastic piece 5. A gasket 10 is also arranged between the elastic piece 5 and the limiting piece 6. In this embodiment, the upright rod 7 is a threaded rod, the elastic member 5 is a spring, and the limiting member 6 is a nut.
The support plate 3 is inverted "U" shaped and includes a first vertical portion 301, a second vertical portion 302, and a horizontal portion 303 connecting the upper ends of the first and second vertical portions 301 and 302. The first vertical portion 301 is connected with the angle steel 12, the first locating plate 1 is fixed on one side, close to the first vertical portion 301, of the second vertical portion 302, the safety switch 4 is fixed on one side, far away from the first vertical portion 301, of the second vertical portion 302 through the fastener 10, and contacts of the safety switch 4 are downward and matched with the second locating plate 2.
The first vertical portion 301 is provided with a waist-round hole, and the support plate 3 is connected with the angle steel 12 through a fastener 9 arranged in the waist-round hole. The waist round hole is arranged, so that the height of the support plate 3 can be adjusted up and down to meet the requirements of different gap heights between the movable cover plate 8 and the angle steel 12, and the application range of the safety monitoring device is wider.
The lower end of the second vertical portion 302 is provided with a bayonet 11 for the second positioning plate 2 to move up and down. The bayonet 11 on the support plate 3 can play a limiting role on the movement of the second positioning plate 2, the phenomenon that the upright rod 7 drives the second positioning plate 2 to move upwards excessively is avoided, the acting force of the second positioning plate 2 on the safety switch 4 is too large due to too large elasticity of the compression spring, and therefore the safety switch 4 is damaged, and the running safety and reliability of an escalator or a moving walk are improved.
In this embodiment, the second positioning plate 2 is fixed to the lower end of the upright 7 by bolts or welding, and the upper portion of the upright 7 movably penetrates through the horizontal portion 303 of the support plate 3. The fastener 9 is a bolt-nut assembly.
The working procedure of the cover plate safety detection device of the escalator or the moving walk of the embodiment is briefly described as follows:
When the movable cover plate 8 is in a closed state, namely, the movable cover plate 8 is positioned above the vertical rod 7, the vertical rod 7 is subjected to the gravity action of the movable cover plate 8, the vertical rod 7 moves downwards, as the limiting piece 6 and the gasket 10 are fixed on the vertical rod, the lower part of the elastic piece 5 is blocked by the first positioning plate 1, the elastic piece 5 is compressed, the elastic piece 5 is in a tightening state, the vertical rod 7 moves downwards to drive the second positioning plate 2 fixed on the lower part of the vertical rod 7 to move downwards, the second positioning plate 2 moves downwards to enable the second positioning plate 2 to be separated from a contact below the safety switch 4, the safety switch 4 is in an open state, and the escalator or the moving walk can normally and safely run.
When the cover plate of the escalator or the moving pavement needs to be maintained or an accident occurs, the movable cover plate 8 is in an open state, namely, the movable cover plate 8 is removed from the upper side of the vertical rod 7, the vertical rod 7 moves upwards due to the elastic force of the elastic piece 5, so that the second positioning plate 2 positioned on the vertical rod 7 is driven to move upwards, the second positioning plate 2 presses the safety switch 4, the safety switch 4 is in a closed state, the safety switch 4 sends out a stop operation signal, the escalator or the moving pavement stops operating, and the safety of maintenance personnel and passengers is protected.
The cover plate safety detection device of the escalator or the moving walk has reasonable structural arrangement, the upright rod is movably arranged on the first positioning plate, the second positioning plate is arranged at the lower end part of the upright rod, the second positioning plate is driven to move by the elasticity of the spring, and the second positioning plate triggers the safety switch to stop the operation of the escalator or the moving walk, so that the safety of maintenance personnel and passengers can be protected, and the operation safety and reliability of the escalator or the moving walk are improved.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
