Drilling device for municipal public engineering construction

Abstract

The invention relates to the technical field of accessory devices of drilling equipment and especially relates to a drilling device for municipal public engineering construction. The device has the beneficial effects that a drilling path of a drill bit can be limited, so probability in skew of the drilling path can be reduced, so drilling quality of the drilling device is increased. The drilling device comprises an enclosure and a drill bit, wherein an installation cavity is disposed inside the enclosure; a power mechanism is disposed in the installation cavity; an output hole is communicatedand formed in the bottom end of the installation cavity; an output end of the power mechanism passes through the output hole from the installation cavity and extends to the lower side of the enclosure; and the drill bit is installed at an output end of the power mechanism. The drilling device also comprises a supporting plate, four groups of supporting legs, four groups of lifting threaded rods, two groups of limiting rods, a limiting plate, a fixation plate, a control rod, an operation plate, two groups of pedals and two groups of operation handles, wherein the left front side, the left rearside, the right front side and the right rear side of the bottom of the supporting plate are connected to top ends of the four groups of lifting threaded rods respectively; and four groups of liftingthreaded grooves are formed in top ends of the four groups of supporting legs respectively.

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
