Dust-proof low-noise punching device for building engineering

Abstract

The invention discloses a dust-proof low-noise perforating device for building engineering, which relates to the technical field of building perforating. The invention comprises a rack; A push-pull handle is fixedly connected on both back sides of the frame; At one end face of that frame, a plurality of elastic position blocks are fixedly connecte; A punch is twisted on two opposite surfaces of the machine frame; The puncher comprises a limiting block; At one end face of that limit block, a plurality of hydraulic rods are fixedly connecte; A fixed block is fixedly connected with one end of a plurality of hydraulic rods away from the limit block; One end face of the fixing block is fixedly connected with a motor; A sound insulation block is fixedly connected with the peripheral side of themotor; A dust-proof part is fixedly connected at one end of the fixing block away from the motor; At one end face of that limit block, a plurality of sliders are fixedly connecte through a shock absorbing spring. Through the design of the dust-proof part, on the one hand, the device can effectively prevent dust from escaping in the drilling process, on the other hand, the dust-proof part can alsobe used as a protection mechanism to prevent substances such as stones from splashing in the crushing process.

Description

technical field [0001] The invention belongs to the technical field of construction drilling, in particular to a dust-proof and low-noise drilling device used in construction engineering. Background technique [0002] Construction engineering refers to the planning, survey, design and construction, completion and other technical work for new construction, reconstruction or expansion of houses, buildings and auxiliary structures, as well as the completed engineering entities and the installation of supporting lines, pipelines and equipment project. [0003] Due to the nature of the construction project itself, the construction project does not need to drill holes all the time, so the frequency of use of the puncher is very high. At present, the drilling method in the construction project generally requires first drawing a cross positioning line on the workpiece, and then drilling with a hand-held electric drill. On the one hand, this punching method is inefficient, and on th...

Problems solved by technology

[0004] The object of the present invention is to provide a dust-proof and low-noise punching device for construction projects. Through the hinged and position-limiting relationship between the punch and the frame, it solves the problem that the existing punching device is not easy to drill oblique holes. It takes time and effort to maintain the angle and it is not easy to maintain stability; through the design of the elastic positioning block, the problem of easy displacement and inaccurate positioning of the existing punching device is solved; through the design of the dustproof part, the problem of The existing punching device is easy to generate dust when punching holes, and the punching device lacks protection devices, which will cause stones and other substances to splash during the punching process, causing damage to the construction workers and the surrounding people; through sound insulation blocks and sound insulation cotton blocks The design of the existing punching device solves the problem that the existing punching device is noisy during the punching process, which will cause hearing damage to the construction and surrounding personnel; through the design of the handle and push-pull handle, it solves the problem that the existing punching device often It is a single-handle structure, and the problem of punching is relatively laborious; through the design of the ruler, it solves the problem that the existing punching device is difficult to control the punching depth
