Protective film fixed-distance section cutting device for highway bridge engineering

Abstract

The invention discloses a protective film fixed-distance sectioning device for highway bridge engineering, and belongs to the technical field of sectioning devices for highway bridge engineering. A protective film fixed-distance sectioning device for highway bridge engineering comprises a sectioning box, a working channel is formed in the lower side of the sectioning box, scale marks are arranged on one side of the bottom face of the working channel, and a synchronous clamping and cutting mechanism is arranged, so that when the device is used, the lever principle can be formed through swinging of a swinging working rod; and meanwhile, the clamping block can apply pressure to the protective film due to the gravity effect, the protective film is further compacted along with the descending of the cutting knife, so that the cutting action is carried out, the cutting is uniform, and meanwhile, the situation that the protective film is not directly disconnected after the cutter is worn is avoided, so that the service life of the protective film is prolonged. And the problem of damage caused by pulling is solved.

Description

technical field [0001] The invention relates to the technical field of cutting devices for highway and bridge engineering, and more specifically relates to a protective film fixed-distance cutting device for highway and bridge engineering. Background technique [0002] Highway and bridge engineering includes bridge main body (namely, bridge superstructure and bridge substructure) engineering and auxiliary engineering facilities in the overall bridge position. During the construction or maintenance of highway and bridge projects, it is necessary to protect the construction links through protective films. The prior art publication number is that the literature of CN213829106U provides a kind of protective film cutting device for road and bridge engineering. There are four universal wheels installed, the stainless steel shell is fixedly connected to the top of the base, the tool box is fixedly connected to the front end of the top of the stainless steel shell, the openable top...

AI Technical Summary

Problems solved by technology

Although this device has many beneficial effects, there are still the following problems: 1. The device 1. pushes the cutting knife through the hydraulic rod to directly cut the protective film. In this process, the protective film is not compacted and fixed for cutting, and there is uneven cutting. Or the protection is not directly disconnected after the tool is worn, but the situation is broken. 2. At the same time, the device cannot control the speed of the knife according to the different materials, so it cannot guarantee the smoothness of the incision. In view of this, we propose a highway bridge engineering Cutting device with protective film at fixed distance
