Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of tunnel construction, more particularly, relate to a tunnel inverted arch trestle fender plate structure with spring handle. BACKGROUND

[0002] At present, the tunnel fender plate mainly relies on manual lifting to complete the construction operation, the stress surface is small, and it is difficult to move the fender plate by relying on manpower alone, part of the trestle is welded and fixed with a handle, which brings inconvenience to passing and exists safety hazards. When the fender plate adopts a fixed handle, the passing is affected, and the working efficiency is affected; at the same time, when there is no fixed handle device, it is difficult to move the fender plate, and it is easy to cause the inconvenience of operation. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the above problems, the utility model adopts the following technical scheme:

[0004] A tunnel inverted arch trestle fender plate structure with spring handle, the fender plate is installed on the bridge deck, the bridge deck is provided with a groove corresponding to the fender plate, one end of the fender plate is hinged to the bridge deck, and the other end is provided with a spring handle for lifting the fender plate.

[0005] Further, the handle of the spring handle is wrapped with a rubber layer.

[0006] Further, the spring handle is fixed on the fender plate by bolts or welding.

[0007] Further, the fender plate and the bridge deck are hinged through a hinge.

[0008] Further, the hinge is two, and the two hinges are symmetrically arranged.

[0009] The utility model has the advantages of:

[0010] The utility model can close the spring handle when the vehicle passes, so that the bridge deck is flat and there is no foreign matter protruding, and the safety of driving is ensured; when in use, the spring handle is pulled open, the fender plate can be efficiently opened, and pouring work can be carried out.

[0011] The utility model connects the fender plate and the bridge deck through the hinge, reduces the loss and damage risk of the fender plate caused by frequent movement, and the spring handle can be frequently operated compared with the fixed handle, and has better stability and safety. DRAWINGS

[0012] Fig. 1 It is a top view schematic diagram of the utility model of a tunnel inverted arch trestle fender plate structure with spring handle;

[0013] Fig. 2The utility model relates to a tunnel inverted arch trestle fender plate structure with spring handle's front view schematic drawing.

[0014] Fig. 3 The utility model relates to a tunnel inverted arch trestle fender plate structure with spring handle's left view schematic drawing.

[0015] In the drawing: 1, spring handle, 2, fender plate, 3, hinge, 4, bridge deck. DETAILED DESCRIPTION

[0016] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0017] Embodiment 1

[0018] Reference Figs. 1 to 3 A tunnel inverted arch trestle fender plate 2 structure with spring handle 1, the fender plate 2 is installed on the bridge deck 4, the bridge deck 4 is provided with recess corresponding to the fender plate 2, one end of the fender plate 2 is hinged to the bridge deck 4, and the other end is provided with spring handle 1 for lifting the fender plate 2.

[0019] In the embodiment, the handle of the spring handle 1 is wrapped with a rubber layer.

[0020] In the embodiment, the spring handle 1 is fixed on the fender plate 2 by bolts or welding.

[0021] In specific implementation, the spring handle and the fender plate are fixed by bolts or welding, the spring handle serves as an extension handle for lifting the fender plate, and the other side of the fender plate is connected to the bridge deck by a hinge, so that the fender plate can be opened and closed.

[0022] When pouring, the spring handle is opened, the fender plate is lifted, and then pouring is started, after pouring is completed, the fender plate is closed and the handle device is closed, so that the road surface is flat and convenient for vehicle passing.

[0023] In the embodiment, the fender plate 2 and the bridge deck 4 are hinged by the hinge 3.

[0024] In the embodiment, the hinge 3 is two, and the two hinges 3 are symmetrically arranged.

[0025] In specific implementation, the utility model can close the spring handle when the road is open, so that the bridge deck is flat and no foreign matter is protruding, and the driving safety is ensured; when in use, the spring handle is pulled open, the operator can conveniently lift the fender plate, the fender plate can be efficiently opened, pouring work is carried out, the work efficiency is improved, and the requirement of humanization design is met.
