Description

Technical Field

[0001] The utility model relates to an anti-jumping and silent drainage ditch cover plate structure. Background Art

[0002] As a common structural form in municipal and architectural design, the gutter cover has become more mature. However, this type of structure still has the following problems that have not been fully solved:

[0003] 1. The cover of the drainage ditch on the road jumps up: The existing drainage ditch cover structure lacks fixed nodes for flexible disassembly and assembly, resulting in the actual cover not being fixed and being placed directly on the base. As a result, the cover jumps up due to uneven force during the wheel rolling process, damaging the vehicle chassis. 2. The problem of noise from passing vehicles: The existing drainage ditch cover has no vibration isolation and noise reduction measures, and there is obvious noise during vehicle driving, which affects the acoustic environment of surrounding buildings. 3. The problem of cumbersome maintenance of bolt-fixed covers: In order to prevent the cover from jumping up, some drainage ditch covers will use bolt-fixed ditch covers, but the maintenance process of this type of ditch cover is more cumbersome than that of ordinary covers, which is not conducive to the maintenance of outdoor drain ditches that require frequent maintenance. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a rationally designed anti-jumping and silent drainage ditch cover structure, which solves the problems of cover jumping, traffic noise and inconvenient maintenance.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problems is: an anti-jumping and silent drainage ditch cover plate structure, including a cover plate and a base, and the base is fixed on the drainage ditch; it is characterized in that: it also includes a fixing bolt, a rubber vibration isolation pad, a metal pressure strip and a metal spring gasket; the metal spring gasket is placed on, and the rubber vibration isolation pad is placed on the metal spring gasket; the metal pressure strip is fixed to the base with screws, and the outer edge of the rubber vibration isolation pad is embedded in the metal pressure strip; the fixing bolt is fixed to the base; the cover plate is placed on the rubber vibration isolation pad; a card groove is provided at the edge of the cover plate, and the card groove is card-connected with the fixing bolt.

[0006] The base described in the utility model is made of angle steel.

[0007] The metal spring gasket of the utility model is placed on the horizontal side of the base, and the fixing bolt is fixed on the vertical side of the base.

[0008] The metal pressure strip described in the utility model is U-shaped.

[0009] The fixing bolts described in the utility model are multiple and arranged horizontally in sequence.

[0010] The clamping slot of the utility model is composed of an inlet and outlet slot section and a fixed slot section; the lower end slot of the inlet and outlet slot section is located at the bottom of the edge of the cover plate, and the upper end slot is communicated with the fixed slot section.

[0011] The fixed groove section of the utility model is a vertical waist shape.

[0012] Compared with the prior art, the utility model has the following advantages and effects: 1. The displacement of the cover plate is limited by the card slot, ensuring that the cover plate will not jump up significantly and damage the vehicle during the driving process of the vehicle. 2. The displacement of the cover plate is limited by the card slot instead of the fixing bolt, which reduces the removal process during the inspection and maintenance process, and is convenient for meeting the needs of frequent maintenance. 3. The metal spring gasket and the rubber vibration isolation pad are used to reduce the impact of the cover plate on the base when the vehicle passes by, and reduce the generation of noise.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0018] The embodiment of the utility model comprises a cover plate 1 , a base 2 , a fixing bolt 3 , a rubber vibration isolation cushion layer 4 , a metal pressure strip 6 and a metal spring gasket 7 .

[0019] The base 2 is fixed on the drainage ditch, and the base 2 is made of angle steel.

[0020] The metal spring washer 7 is placed on the horizontal side of the base 2 , and the rubber vibration isolation pad 4 is placed on the metal spring washer 7 . The thickness of the rubber vibration isolation pad 4 is 7 mm.

[0021] The metal strip 6 is fixed on the base 2 by M10 screws 5 , and the metal strip 6 is U-shaped; the outer side edge of the rubber vibration isolation pad 4 is embedded in the metal strip 6 .

[0022] The fixing bolts 3 are welded and fixed on the vertical side of the base 2. There are multiple fixing bolts 3, which are arranged horizontally in sequence, with one bolt being provided every 250 mm.

[0023] The cover plate 1 is placed on the rubber vibration isolation pad 4; a clamping groove 8 is provided at the edge of the cover plate 1, and the clamping groove 8 is clamped with the fixing bolt 3 to form a constraint and fixation for the cover plate 1. The clamping groove 8 consists of an inlet and outlet groove section 81 and a fixing groove section 82; the lower end groove of the inlet and outlet groove section 81 is located at the bottom of the edge of the cover plate 1, and the upper end groove is connected with the fixing groove section 82; the fixing groove section 82 is a vertical waist shape, which is easy to install and can provide the fixing bolt 3 with a small range of vertical displacement.

[0024] The installation and working process of the utility model is:

[0025] Installation of base 2: On the concrete structure of the drainage ditch, base 2 is installed at the edge of the drainage ditch. Angle steel is used for masonry protection, and metal spring washers 7 and rubber vibration isolation pads 4 are placed on the base 2. The outer side of the rubber vibration isolation pad 4 is embedded with metal strips 6 and fixed with M10 screws 5. A φ5 welded fixing bolt 3 is set every 250mm on the vertical side of the base 2.

[0026] Installation method: Align the lower notch of the inlet and outlet slot section 81 with the fixing bolt 3, then lower the cover plate 1, insert the fixing bolt 3 into the inlet and outlet slot section 81, and push downward along the slot 8, the fixing bolt 3 finally enters the fixing slot section 82, and after the rubber rebounds to the upper end of the fixing slot section 82, the installation is completed. When inspecting, pull the cover plate 1 in the opposite direction along the lower edge of the slot 8 to remove the cover plate 1.

[0027] Working mode: During the driving process of the vehicle, the cover plate 1 is warped due to uneven force, but is constrained to a small range of vertical displacement due to the fixation of the card slot 8. In this process, due to the effect of the rubber vibration isolation pad 4, the cover plate 1 is not in direct contact with the base 2, which reduces the generation of noise. The metal spring gasket 7 supports and cushions the rubber vibration isolation pad 4, extending the service life of the component.

[0028] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
