Description

Technical Field

[0001] The utility model relates to the technical field of traffic road engineering, in particular to a city traffic road drilling machine. Background Art

[0002] At present, various warning poles are often required to be installed in urban traffic road projects, so a drilling machine is needed to drill holes on the road surface, through which the warning poles can be installed.

[0003] Among them, the disclosure (announcement) number: CN218092892U discloses a road drilling machine for urban roads and traffic engineering, including a base, a support frame and a box body are installed on the top surface of the base, a drilling mechanism is arranged on the bottom surface of the support frame, and the drilling mechanism is composed of a hydraulic cylinder, a protective box, a motor, a rotating drum, a drill rod, a spring, a fixed block and a pull rod. A hydraulic cylinder is installed on the bottom surface of the support frame, a protective box is installed on the power output end of the hydraulic cylinder, a motor is arranged in the protective box, a rotating drum is connected to the power output end of the motor, the rotating drum is located outside the protective box, and a drill rod is inserted in the rotating drum.

[0004] In the above scheme, the motor and the drill rod are driven downward by the hydraulic cylinder to drill holes on the road surface. However, in actual use, it is found that the hydraulic cylinder drives the drill rod downward, but the hydraulic cylinder cannot accurately control the downward movement distance of the drill rod, resulting in the drill rod being driven under the base of the road, which not only does useless work, but also causes great damage to the road. Therefore, an urban traffic road drilling machine is proposed. Utility Model Content

[0013] Compared with the prior art, the utility model provides an urban traffic road drilling machine, which has the following beneficial effects:

[0014] 1. The urban traffic road drilling machine is provided with a U-shaped moving rod, a limiting support ring, a screw and a rotating handle. When the mounting seat and the motor are driven downward by the hydraulic cylinder, the mounting seat will be in contact with the limiting support ring. At this time, the limiting support ring can limit the depth of the drill rod and the drilling head on the motor to penetrate into the road surface, which can avoid causing greater damage to the road surface, and the drill rod and the drilling head will not do useless work. When it is necessary to adjust the depth of the drilling, it is only necessary to turn the rotating handle by hand to rotate the screw. During the rotation, the screw drives the U-shaped moving rod downward, so that the limiting support ring can move up and down and adjust the limited moving distance of the mounting seat.

[0015] 2. The urban traffic road drilling machine is provided with a vacuum cleaner and a vacuum tube. The operation of the vacuum cleaner can make the interior of the vacuum tube a negative pressure state. Since the vacuum tube is connected to the limit support ring, the interior of the limit support ring can be in a negative pressure state, so that the dust generated during the drilling process can be absorbed through the vacuum hole to avoid dust pollution of the environment.

[0016] 3. The urban traffic road drilling machine is provided with a mounting ring and bolts. The mounting ring can be separated from the drilling head by loosening the bolts with a wrench, so that the drilling heads of different sizes can be replaced.

[0017] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has a structure for limiting the downward movement of the drill rod and the drilling head, so that the drill rod and the drilling head will not be driven into the road base, reducing the degree of damage to the road caused by drilling. At the same time, the drilling machine will not do useless work, and its utilization efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
