[0002] During the construction of a highway, it is necessary to build the foundation to minimize the impact of gravity on the road surface when large vehicles pass through. There are rocks under the surface in some areas. To ensure normal construction operations, a rock drill is needed.

[0003] During the use of existing rock drills, although they can perform rock drilling and hole drilling, there is no mechanism for dust reduction operations for dust in existing rock drills, and there is also no mechanism for cooling the drill bit when the drill bit contacts the rock. Therefore, the dust has a greater impact on the surrounding personnel, and the high temperature generated by friction also increases the wear of the drill bit and reduces the service life of the drill bit. For this reason, we have proposed a rock drill for highway construction. Content of the Utility Model

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1 - 4 , a rock drill for road construction, including a housing 1. An electric telescopic rod 2 is fixedly assembled at the top of the housing 1. The output shaft of the electric telescopic rod 2 is fixedly assembled with a lifting platform 7. A motor 3 and a pressing rod 4 are respectively fixedly assembled at the top of the lifting platform 7. The output shaft of the motor 3 is fixedly sleeved with a drill rod 6. A through hole 9 is opened at the top of the housing 1. A sliding hole 10 is opened at the top of the inner wall of the housing 1. Water inlet pipes 5 are provided on both sides of the housing 1. A water tank 11 is fixedly assembled on the inner wall of the housing 1. An atomizing nozzle 12 is provided on the outer wall of the water tank 11. A sleeve 13 is fixedly assembled at the top of the water tank 11. Limiting grooves 8 are opened on both inner walls of the housing 1.

[0021] In the above structure, through the structures of the housing 1, the electric telescopic rod 2, the motor 3, the pressing rod 4, the water inlet pipe 5, the drill rod 6, and the sleeve 13, when the motor 3 drives the drill rod 6 to rotate and drill holes in the rock during the operation of the rock drill, the extension of the output shaft of the electric telescopic rod 2 is used to make the drill rod 6 contact the rock, so that the lifting platform 7 descends and drives the pressing rod 4 to descend synchronously, thereby enabling the piston to squeeze the dust suppression water inside the sleeve 13 to achieve dust suppression operation, and further reducing the impact of dust on surrounding personnel.

[0022] In a preferred embodiment: The inner wall of the limiting groove 8 is slidably connected to the outer wall of the lifting platform 7. The diameter of the water inlet pipe 5 is 2 cm larger than the diameter of the motor 3.

[0023] In the above structure, through the structure of the limiting groove 8 provided, the lifting platform 7 is limited by the limiting groove 8 during the lifting process and cannot shake or even shift in position, thereby improving the stability of the lifting platform 7 during the lifting process. The water inlet pipe 5 can provide sufficient space for the movement of the motor 3 during the lifting of the lifting platform 7 to ensure the normal operation of the device.

[0024] In a preferred embodiment: The number of the electric telescopic rods 2 is two, and the two electric telescopic rods 2 are symmetrically distributed along the top of the housing 1.

[0025] In the above structure, through the two electric telescopic rods 2 provided, both ends of the lifting platform 7 can be driven to lift, avoiding the impact of the vibration force received by the lifting platform 7 during the lifting process on the movement of the lifting platform 7, and thus ensuring that the drill pipe 6 can closely adhere to the rock for drilling operations.

[0026] In a preferred embodiment: A piston is fixedly assembled at one end of the extrusion rod 4 located on the inner wall of the sleeve 13. The inner walls of the sleeve 13 and the water tank 11 are both filled with dust suppression water, and the inside of the sleeve 13 communicates with the inside of the atomizing nozzle 12 through the water tank 11.

[0027] In the above structure, through the sleeve 13 and the atomizing nozzle 12 provided, when the lifting platform 7 is lifting, the dust suppression water is ejected through the atomizing nozzle 12 by using the lifting of the extrusion rod 4, so that the dust suppression water adsorbs the dust in the air, and at the same time, it can also cool the contact area between the drill pipe 6 and the rock, thereby ensuring that the degree of influence of the drill pipe 6 by high temperature is minimized, and further extending the service life of the drill pipe 6.

[0028] In a preferred embodiment: The outer wall of the extrusion rod 4 is slidably connected to the inner wall of the sliding hole 10, and the extrusion rod 4 is made of galvanized iron metal. The bottom end of the drill pipe 6 is provided with a drill bit.

[0029] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear degree of the extrusion rod 4 during the operation process, thereby extending the service life of the extrusion rod 4. At the same time, the galvanized iron metal also has the characteristic of low cost, reducing the production cost and maintenance cost of the device.

[0030] In a preferred embodiment: When the top of the piston abuts against the top of the inner wall of the sleeve 13, the distance between it and the water inlet pipe 5 is 1 cm. One-way valves and solenoid valves are respectively provided on the inner walls of the water inlet pipe 5 and the atomizing nozzle 12.

[0031] In the above structure, by using the distance between the water inlet pipe 5 and the piston, it can be ensured that after the lifting platform 7 is reset, the distance between the piston and the water inlet pipe 5 enables the dust suppression water to be only directly below the piston when the operator is performing the water injection operation, so as to ensure that the extrusion rod 4 exerts pressure on the dust suppression water after descending, and thus realizes the effect of generating water pressure to eject the dust suppression water.

[0032] Working principle: First, after the user assembles the device, the device is filled with water through the water inlet pipe 5. Subsequently, the lifting platform 7 descends through the extension of the output shaft of the electric telescopic rod 2 and the operation of the motor 3. At the same time, the drill rod 6 rotates and touches the rock, thereby achieving the effect of rock drilling operation. During the descent of the lifting platform 7, the piston applies pressure to the dust suppression water in the casing 13 and the water tank 11, so that the dust suppression water is sprayed out through the atomizing nozzle 12, thereby enabling the dust to be adsorbed, reducing the impact of the dust on the surrounding personnel, and at the same time being able to cool the drill rod 6 to ensure the service life of the drill rod 6 until the operation ends.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
