Drilling device for construction of municipal public works

Abstract

The invention relates to the technical field of drilling equipment attachments, in particular to a drilling device for municipal public works construction, which can limit the drilling path of the drill bit to reduce the probability of the drilling path of the drill bit being skewed, thereby improving the The drilling quality of the drilling device; including the casing and the drill bit, the inside of the casing is provided with an installation cavity, the installation cavity is provided with a power mechanism, the bottom of the installation cavity is connected with an output hole, and the output end of the power mechanism is connected to the installation cavity. The drill bit is installed at the output end of the power mechanism; it also includes support plates, four sets of legs, four sets of lifting threaded rods, two sets of limit rods, limit plates, fixed Board, control rod, control panel, two sets of pedals and two sets of control handles, the left front side, left rear side, right front side and right rear side of the bottom end of the support plate are respectively connected with the top ends of four sets of lifting threaded rods, four sets of outriggers There are four sets of lifting thread grooves respectively arranged on the top.

Description

technical field [0001] The invention relates to the technical field of drilling equipment attachments, in particular to a drilling device for municipal public works construction. Background technique [0002] As we all know, municipal public facilities include urban roads and their facilities, urban bridges and culverts and their facilities, urban drainage facilities, urban flood control facilities, urban road lighting facilities, and urban construction public facilities, among which urban roads and their facilities include the installation of urban road guardrails , and the drilling device for municipal public works construction is a device used to drill holes on urban roads during the construction of urban road guardrail installation projects, and it has been widely used in the field of municipal public works construction Existing municipal public works construction drilling device comprises casing and drill bit, and the inside of casing is provided with installation cavit...

[0002] As we all know, municipal public facilities include urban roads and their facilities, urban bridges and culverts and their facilities, urban drainage facilities, urban flood control facilities, urban road lighting facilities, and urban construction public facilities, among which urban roads and their facilities include the installation of urban road guardrails , and the drilling device for municipal public works construction is a device used to drill holes on urban roads during the construction of urban road guardrail installation projects, and it has been widely used in the field of municipal public works construction Existing municipal public works construction drilling device comprises casing and drill bit, and the inside of casing is provided with installation cavity, is provided with power mechanism in the installation cavity, and the bottom end of installation cavity is communicated with and is provided with output hole, the output of power mechanism The end passes through the output hole in the installation cavity and extends to the lower side of the casing, the drill bit is installed at the output end of the power mechanism, and the casing is provided with a handle assembly; when the existing drilling device for municipal public works construction is used, First, draw the drilling points on the road where the urban road guardrail needs to be installed, and then the staff manipulates the casing through the handle assembly, so that the drill tip of the drill at the bottom of the casing is aligned with the drilling point, and then starts the machine inside the casing. The power mechanism makes the output end of the power mechanism drive the drill bit to rotate. During this process, the staff need to apply reasoning to the casing until the drilling operation is completed; it is found in the use of the existing drilling device for municipal public works that the staff controls the drill When the hole device is drilling on the road, due to human factors, the drilling path of the drill bit may be skewed, thus reducing the drilling quality of the drilling device, resulting in poor practicability
