Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic shield-shaped gate accessories, in particular to a hinge cover plate for fixing a pneumatic shield-shaped gate. Background Art

[0002] In the pneumatic shield gate system, the airbag is inflated and deflated to achieve the lifting and lowering of the gate, and the hinged cover plate, as one of the important accessories of the pneumatic shield gate system, is mainly hinged at the end of the gate to meet the positioning requirements of the gate plate. When the pneumatic shield gate is lifted and lowered, the hinged cover plate must complete the bending action. During the bending process, the hinged cover plate will be pulled and squeezed, thereby ensuring that the steel gate is connected to the pneumatic gate dam foundation, and at the same time arranged along the length of the gate to meet the requirements of sealing and waterproofing.

[0003] At present, most of the existing hinge cover plates are made of ordinary rubber. During the reciprocating bending process, cracks and wrinkles are prone to occur, which shortens their service life and has to be replaced frequently, which not only increases the cost of use, but also affects the interception effect of the pneumatic gate. Utility Model Content

[0004] In response to the above-mentioned problems, the present application provides a hinged cover plate for fixing a pneumatic shield gate. By setting the traditional hinged cover plate into a horizontal "S" shape and adopting a flexible multi-layer structure, not only the material properties of the cover plate itself are improved and environmental requirements are met, but the guide rollers also limit the bending path, thereby avoiding excessive bending of the hinged cover plate. This extends its service life, reduces the cost of use, and improves the interception effect of the pneumatic gate.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a hinged cover plate for fixing a pneumatic shield gate includes a hinged cover plate body, the hinged cover plate body is in a horizontal "S" shape as a whole, an anti-deformation seat is fixedly connected to the upper end of the hinged cover plate body, the upper end of the anti-deformation seat is fixedly connected to the gate plate, and bolt holes are arranged linearly on the horizontal surface of the lower end of the hinged cover plate body, and a main chain bolt for fixing the hinged cover plate body and the concrete foundation is arranged in the bolt hole;

[0006] The hinge cover body is made of a combination of a flexible material layer and a metal frame, and the metal frame is evenly and adaptively installed inside the flexible material layer.

[0007] Preferably, the lower end of the side wall of the gate plate is symmetrically hinged with a side plate, and the lower end of the side plate is fixedly connected to the upper end of the concrete foundation.

[0008] Preferably, a transverse axis is fixedly installed between the opposite side walls of the two side panels, and a guide roller is rotatably installed on the transverse axis.

[0009] Preferably, the outer side wall of the guide roller fits in an arcuate portion of the surface of the hinge cover body.

[0010] Preferably, the outer side of the flexible material layer is coated with an anti-ultraviolet paint layer, and the outer side of the paint layer is coated with an interlayer adhesive.

[0011] Preferably, the metal skeleton is a spiral steel wire bundle formed by twisting multiple strands of fine steel wires.

[0012] The beneficial effects of the utility model are as follows:

[0013] (1) The hinged cover plate for fixing the pneumatic shield gate described in the utility model, by setting the traditional hinged cover plate into a horizontal "S" shape and adopting a flexible multi-layer structure, not only improves its own material properties and meets environmental requirements, but also the anti-ultraviolet paint layer can improve the sun resistance of the hinged cover plate body. The setting of the interlayer glue can prevent the paint layer on the surface of the hinged cover plate body from falling off during the reciprocating bending process, resulting in cracks in the hinged cover plate body, thereby extending the service life.

[0014] (2) The hinged cover plate of the fixed pneumatic shield gate described in the utility model is provided with a guide roller that can limit the bending path of the hinged cover plate body, thereby avoiding excessive bending of the hinged cover plate, extending its service life, reducing the number of replacements, and reducing the cost of use, while also ensuring the interception effect of the pneumatic gate.

[0025] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0026] like Figure 1-Figure 6 As shown, the hinged cover plate for fixing the pneumatic shield gate includes a hinged cover plate body 1, and the hinged cover plate body 1 is in a horizontal "S" shape as a whole. An anti-deformation seat 11 is fixedly connected to the upper end of the hinged cover plate body 1, and the upper end of the anti-deformation seat 11 is fixedly connected to the gate plate 2. Bolting holes are arranged linearly on the horizontal surface of the lower end of the hinged cover plate body 1, and main chain bolts 4 for fixedly connecting the hinged cover plate body 1 and the concrete base 3 are arranged in the bolting holes.

[0027] The hinge cover body 1 is composed of a flexible material layer 12 and a metal frame 13, and the metal frame 13 is evenly and adaptively installed inside the flexible material layer 12. The outer side of the flexible material layer 12 is coated with an anti-ultraviolet paint layer, and the outer side of the paint layer is coated with an interlayer glue. The metal frame 13 is a spiral steel wire bundle formed by twisting multiple strands of fine steel wires.

[0028] During specific operation, clean compressed air is used as the driving medium to fill the airbag 5 to expand it. The expanded airbag 5 will drive the gate plate 2 to rotate upward at its lower end hinge point, thereby intercepting the water flow. The inhibition belt 6 can control the angle range of the gate plate 2 to rotate upward, so that the pneumatic shield gate can operate normally. During the rotation of the gate plate 2, the anti-deformation seat 11 can improve the stability of the connection between the hinge cover plate body 1 and the gate plate 2. At the same time, the hinge cover plate body 1 will be bent, and the flexible material layer 12 and the metal frame 13 can adapt to this action. At the same time, the anti-ultraviolet paint layer can improve the anti-sun performance of the hinge cover plate body 1. The setting of the interlayer glue can prevent the paint layer on the surface of the hinge cover plate body 1 from falling off during the reciprocating bending process, so that cracks appear on the hinge cover plate body 1.

[0029] The lower end of the side wall of the gate plate 2 is symmetrically hinged with a side panel 21, and the lower end of the side panel 21 is fixedly connected to the upper end of the concrete base 3. A horizontal shaft 14 is fixedly installed between the opposite side walls of the two side panels 21, and a guide roller 15 is rotatably installed on the horizontal shaft 14. The outer side wall of the guide roller 15 fits with the arc portion of the surface of the hinge cover body 1.

[0030] During specific operation, when the gate plate 2 drives the hinge cover plate body 1 to perform reciprocating bending, the guide roller 15 can play a guiding and limiting role for the hinge cover plate body 1 and the approaching end of the gate plate 2, so that the hinge cover plate body 1 has the same bending arc path each time, thereby reducing the possibility of cracks in the hinge cover plate body 1 and extending its service life.

[0031] Working principle: clean compressed air is used as the driving medium, which is filled into the airbag 5 to expand it. The expanded airbag 5 will drive the gate plate 2 to rotate upward at its lower hinge point, thereby intercepting the water flow. The inhibition belt 6 can control the angle range of the gate plate 2 to rotate upward, so that the pneumatic shield gate can operate normally. During the rotation of the gate plate 2, the anti-deformation seat 11 can improve the stability of the connection between the hinge cover plate body 1 and the gate plate 2. At the same time, the hinge cover plate body 1 will be bent, and the flexible material layer 12 and the metal frame 13 can adapt to this action. At the same time, the anti-ultraviolet paint layer can improve the sun resistance of the hinge cover plate body 1. The setting of the interlayer glue can prevent the paint layer on the surface of the hinge cover plate body 1 from falling off during the reciprocating bending process, so that cracks appear on the hinge cover plate body 1.

[0032] When the gate plate 2 drives the hinge cover plate body 1 to perform reciprocating bending, the guide roller 15 can play a guiding and limiting role on the hinge cover plate body 1 and the approaching end of the gate plate 2, so that the hinge cover plate body 1 has the same bending arc path each time, thereby reducing the possibility of cracks in the hinge cover plate body 1 and extending its service life.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
