Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drilling device for municipal public engineering construction. Background Art

[0002] Municipal public works include road projects, drainage projects, outdoor construction projects, etc. During the construction of municipal public works, it is necessary to drill holes in the outdoor ground to facilitate the construction and installation of other facilities. The device for drilling holes in the outdoor ground is also called a drilling machine.

[0003] The existing drilling devices have the problem that the spiral drilling rod cannot move downward stably according to the soil environment when moving downward to drill the hole;

[0004] The reason for this problem is that when the drilling device is drilling a hole in the ground, it is necessary to first place the drilling machine above the position where the hole needs to be drilled, then start the motor to drive the spiral drilling rod to rotate, and then move the spiral drilling rod downward to drill the ground position. The soil conditions outdoors are different. The soil conditions are affected by the environment, making some soils harder and there are a lot of gravel on the ground, while the soil in some positions is relatively moist and sparse. If the drilling device is manually pushed downward, when drilling a hole in the ground with hard soil and more gravel, the spiral drilling rod of the drilling machine collides with the gravel in the ground during rotation, which will generate a repulsive force to the side, resulting in the inability to manually control the downward force, which will not only make the drilling process very difficult, but also affect the quality of the drilling. If drilling is performed on a relatively moist and sparse ground, there is no requirement or restriction on the downward force when drilling, which makes it difficult for the user to balance the force, making it easy for the position of the drilling machine to shift during the downward movement, which will also affect the drilling quality of the drilling machine. Therefore, we propose a drilling device for municipal public works construction. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The embodiment of the present application solves the problem that the spiral drilling rod of the existing drilling device cannot stably move downward according to the soil environment when moving downward to drill a hole by providing a drilling device for municipal public works construction.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses a binding device for file arrangement.

[0029] According to the attached Figure 1-6 As shown, it includes a main frame 1, a spiral drilling rod 102 is installed on the front of the main frame 1, a supporting mechanism is arranged on the back of the main frame 1, the supporting mechanism includes a supporting plate 2, which is arranged on the back of the spiral drilling rod 102, the supporting plate 2 is slidably connected to the inside of the main frame 1, the supporting plate 2 supports the spiral drilling rod 102, a moving plate 202 is installed above the supporting plate 2, the moving plate 202 is slidably arranged inside the main frame 1, the moving plate 202 is used to drive the support plate 2 to move, and a hydraulic telescope 207 is installed inside the main frame 1, and the hydraulic telescope 207 is installed above the moving plate 202.

[0030] A motor 101 is installed on the front of the main frame 1, and a spiral drilling rod 102 is installed on the outer surface of the output end of the motor 101. A fixed plate 201 is fixedly connected to the outside of the motor 101, and the movable plate 202 is fixedly connected to the outside of the fixed plate 201. A limiting rod 208 is fixedly connected to the inside of the main frame 1, and the fixed plate 201 is slidably connected to the outside of the limiting rod 208.

[0031] The inner wall of the main frame 1 is fixedly connected with a support block 206, and the support block 206 is fixedly connected to the side of the hydraulic expander 207. The bottom of the movable plate 202 is fixedly connected with a threaded rod 203, and the threaded rod 203 is movably inserted into the inside of the support plate 2. The external thread of the threaded rod 203 is connected with a nut cap, and the outer surface of the nut cap is against the lower surface of the support plate 2.

[0032] Sliding grooves 209 are provided on both sides of the main frame 1, and a pushing member 204 is fixedly connected to the lower surface of the support plate 2. The pushing member 204 is slidably connected to the inside of the sliding groove 209, and a pull rod 205 is fixedly connected to the inside of the pushing member 204. The drilling machine is placed above the position where a hole needs to be drilled, and then the motor 101 is started to drive the spiral drilling rod 102 to rotate, and then the spiral drilling rod 102 is moved downward to drill a hole at the ground position.

[0033] By moving the support plate 2 to the lower position of the movable plate 202, the support plate 2 will be sleeved on the outside of the threaded rod 203, and then the nut cap will be installed on the outside of the threaded rod 203, and then the telescopic rod inside the hydraulic telescope 207 will be started to push the movable plate 202 downward. When the movable plate 202 moves downward, it will drive the support plate 2 to move downward. The support plate 2 will then drive the motor 101 and the spiral drilling rod 102 to move downward, so that the spiral drilling rod 102 can drill holes on the ground with harder soil under a steady force. When drilling holes on a road surface with relatively moist and sparse soil, it is not necessary to use the steady force of the electric motor, and the nut cap is removed to release the space between the movable plate 202 and the support plate 2. By fixing the pull rod 205, the support plate 2 can be driven to move downward, and the pushing member 204 will slide inside the main frame 1, and the fixed plate 201 will also slide outside the limiting rod 208. By releasing or fixing the connection between the movable plate 202 and the support plate 2, the movement mode of the spiral drilling rod 102 is divided into two types: electric and manual. At the same time, the limiting rod 208 has a limiting effect on the movement of the support plate 2, making the movement of the spiral drilling rod 102 more stable, and different movement modes can be used in different ground environments without wasting unnecessary resources, thereby increasing the flexibility of the drilling machine and making the movement of the spiral drilling rod 102 more stable during the drilling process while adapting to the environment.

[0034] The push member 204 and the support plate 2 are driven to move by the pull rod 205, so that the support plate 2 can be more easily subjected to force under human push, and the push member 204 slides inside the sliding groove 209, which has a certain limiting effect on the movement of the movable plate 202, making the movable plate 202 more stable under human push.

[0035] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0036] The support plate 2 and the movable plate 202 are fixed by using the threaded rod 203 and the nut cap, and then the telescopic rod inside the hydraulic telescopic device 207 is started to push the movable plate 202 to move downward. When the movable plate 202 moves downward, the support plate 2 will be driven downward. The hydraulic telescopic device 207 can drive the spiral drilling rod 102 to move downward smoothly without being affected by external forces, and can drill holes on the ground with harder soil. When drilling holes on the road surface with relatively moist and sparse soil, the fixation between the movable plate 202 and the support plate 2 is released, and the pull rod 205 can be pushed to drive the support plate 2 to move downward. By releasing or fixing the connection relationship between the movable plate 202 and the support plate 2, the movement modes of the spiral drilling rod 102 are divided into two types. Both movement modes can use the limit rod 208 to limit the position, making the movement of the spiral drilling rod 102 more stable, and different movement modes can be used in different ground environments without wasting unnecessary resources, thereby increasing the flexibility of the drilling machine.
