Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting tools, and more specifically, particularly relates to a bridge cover plate quick clamp. Background Art

[0002] In bridge engineering, thin cables are slender components that support the bridge and are distributed on both sides of the bridge body. In order to prevent environmental corrosion, they are protected by covers. During bridge maintenance and inspection, the health of the thin cables is crucial and they need to be inspected regularly. Inspection requires removal of the covers used to protect the thin cables. Currently, the removal of the covers requires the use of clamping tools to clamp the covers in advance and fix them with bolts and other tools, and then the clamping tools are connected and lifted during the hoisting. The workers install the clamping tools in dangerous and narrow environments, which takes too long and has a high risk factor.

[0003] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a bridge cover quick clamp is provided to achieve a more practical purpose. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a bridge cover quick clamp to solve the problem that workers have to install clamping tools before lifting the bridge cover in dangerous and narrow environments, which results in long installation time and high risk factor.

[0005] The purpose and effect of the quick clamp for bridge cover of the utility model are achieved by the following specific technical means:

[0006] A quick clamp for a bridge cover comprises a base plate, a connecting plate is arranged at the edge of the base plate, the angle between the base plate and the connecting plate is less than or equal to ninety degrees, a top plate is arranged above the base plate, a handle is hinged on the upper surface of the top plate, and the other end of the handle is hinged on the connecting plate, so that the base plate, the connecting plate and the handle form a triangular structure as a whole, and one end of the handle extends through the connecting plate and is provided with a traction hole.

[0007] Furthermore, a movable groove is vertically opened on the connecting plate, and connecting seats symmetrically located on both sides of the movable groove are arranged at the bottom of the connecting plate. A rotating shaft is arranged on the buckle, and the rotating shaft is passed through the two connecting seats. The buckle extension part is passed through the movable groove.

[0008] Furthermore, a notch is opened on the bottom plate to form a U-shaped plate, and the connecting plate is triangular in shape.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The clamp is set up in a triangular structure. Two clamps are placed at both ends of the cover plate respectively. The bottom plate and the top plate are placed on both sides of the cover plate. The traction rope passes through the traction hole to connect the buckles of the two clamps. The cover plate can be lifted by directly hooking the traction rope. During the lifting process, the top of the buckle is swung up, and the bottom plate and the top plate are automatically closed to clamp the cover plate, realizing quick clamping without the help of other tools, reducing the installation time of the staff.
