Description

Technical Field

[0001] This utility model relates to the field of municipal engineering construction technology, and in particular to a new type of drilling equipment for municipal engineering. Background Technology

[0002] In drilling operations for water conservancy and hydropower projects, the primary problem with current drilling equipment is the release of large amounts of dust into the air. This not only pollutes the surrounding environment but also poses a serious threat to the lung health of construction workers who are susceptible to inhaling this floating dust. Secondly, when drilling operations last for extended periods, the drill bit often overheats due to continuous operation, directly shortening its lifespan. Furthermore, the intense construction noise and mechanical vibrations accompanying drilling operations disrupt the tranquility of the construction site and contradict the principles of safe and civilized construction. Therefore, developing a new type of drilling equipment for municipal engineering that can solve the problems of existing technologies has become a pressing technical challenge. Utility Model Content

[0003] Based on the aforementioned technical problems, this utility model proposes a new type of drilling equipment for municipal engineering to solve the problems existing in the background technology.

[0004] In view of this, the present invention proposes a novel drilling device for municipal engineering, comprising: a drilling machine, a crossbeam mounted on the drilling machine via a cylinder, a stabilizing bracket mounted on one side of the crossbeam, a motor and an impeller pump mounted on the top of the stabilizing bracket, a drill bit mounted on the output end of the motor passing through the stabilizing bracket, a sleeve fitted around the drill bit at the bottom of the stabilizing bracket, the sleeve being a telescopic structure, a rubber pad mounted at the bottom of the sleeve, bevel gears meshing with each other mounted on the upper part of the motor output end and the power input end of the impeller pump, and the water outlet port of the impeller pump being located inside the sleeve via a pipe.

[0005] Furthermore, the sleeve includes multiple sleeves with diameters decreasing sequentially from top to bottom. The inner wall of the sleeve is provided with a cavity, and a spring is provided in the cavity. A slider is provided on the upper part of the sleeve, and the upper part of the sleeve can be telescopically engaged with the cavity of the top sleeve through the slider.

[0006] Furthermore, multiple sets of support blocks are arranged circumferentially on the top wall inside the sleeve, and nozzles are provided on the support blocks. The water inlet end of each nozzle is connected to the water outlet port of the impeller pump.

[0007] Furthermore, the output end of the motor is coaxially provided with a disc at the lower part of the nozzle, and a wedge-shaped block is provided on the disc to disperse the water flow.

[0008] Furthermore, multiple sets of the cylinders are evenly arranged between the drilling machine and the crossbeam.

[0009] Furthermore, the drilling machine is also equipped with a water storage tank, and the water inlet port of the impeller pump is sealed and connected to the bottom of the water storage tank.

[0010] Furthermore, the inner wall of the sleeve is filled with sound-insulating material, which is sound-insulating cotton.

[0011] Furthermore, the drilling machine is equipped with casters at the four corners of its bottom.

[0012] This utility model proposes a novel drilling device for municipal engineering. Compared with the prior art, this utility model solves three major technical problems: First, it addresses the dust problem generated during the drilling process of existing drill bits. This dust not only pollutes the air environment but also poses a potential threat to the lung health of workers. Second, it proposes an effective solution to the overheating of drill bits caused by prolonged drilling operations, thereby extending the service life of the drill bits. Finally, this utility model also provides corresponding improvement measures to address the high decibel construction noise and strong mechanical vibration problems associated with drilling operations, striving to create a safer and lower-noise construction environment.

[0013] This invention employs an adjustable-length sleeve design with a rubber pad at the bottom of the sleeve, creating a sealed working environment. During drilling operations, this design not only effectively reduces mechanical vibration and noise but also greatly limits dust escape, protecting the respiratory system of construction workers.

[0014] Furthermore, the integrated water pump mechanism can perform a water spraying function, which has a significant dual effect: firstly, it further enhances the dust removal effect through water spraying; secondly, it effectively prevents excessive wear of the drill bit due to high-temperature operation by utilizing the cooling effect of the water flow. Particularly noteworthy is that the water spraying and drilling operations share the same motor's driving force, a design that cleverly achieves highly efficient energy utilization.

[0022] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the contents disclosed below.

[0024] The following combination Figures 1 to 6 The technical solution of this utility model will be further explained.

[0025] First embodiment, such as Figures 1 to 6 The image shows a novel drilling device for municipal engineering, comprising: a drilling machine 1, a crossbeam 2 mounted on the drilling machine 1 via a cylinder 3, a stabilizing bracket mounted on one side of the crossbeam 2, a motor 4 and an impeller pump 13 mounted on the top of the stabilizing bracket, a drill bit 5 mounted on the output end of the motor 4 passing through the stabilizing bracket, a sleeve 6 fitted around the drill bit 5 at the bottom of the stabilizing bracket, the sleeve 6 being a telescopic structure, a rubber pad 10 mounted at the bottom of the sleeve 6, bevel gears meshing with each other on the upper part of the output end of the motor 4 and the power input end of the impeller pump 13, a first bevel gear 12 mounted on the motor 4, a second bevel gear 14 mounted on the impeller pump 13, and a water outlet port of the impeller pump 13 connected to the sleeve 6 via a pipe.

[0026] The sleeve 6 comprises multiple sleeves 6 with diameters decreasing sequentially from top to bottom. Each sleeve 6 has an inner wall with a cavity 7, and a spring 9 is installed within the cavity 7. A slider 8 is located at the upper part of each sleeve 6, allowing the upper part of each sleeve 6 to be retractably engaged with the cavity 7 of the top sleeve 6 via the slider 8. Multiple sets of support blocks 16 are circumferentially arranged on the top wall of each sleeve 6, and nozzles 19 are hinged to each support block 16. The water inlet ends of each nozzle 19 communicate with the water outlet port of the impeller pump 13.

[0027] The output end of the motor 4 is coaxially mounted with a disc 17 at the lower part of the nozzle 19, and a wedge-shaped block 18 for dispersing water flow is mounted on the disc 17. Multiple sets of cylinders 3 are evenly arranged between the drilling machine 1 and the crossbeam 2, preferably four sets. A water storage tank 15 is also provided on the drilling machine 1, and the inlet port of the impeller pump 13 is sealed to the bottom of the water storage tank 15. The inner wall of the sleeve 6 is filled with sound-insulating material, namely sound-insulating cotton 11. Casters are respectively provided at the four corners of the bottom of the drilling machine 1.

[0028] Its components include the main body of the drilling machine 1, the crossbeam 2 frame, the pneumatic cylinder 3, the stable support, the drive motor 4, the professional drill bit 5, the multi-stage sleeve assembly 6, and the high-efficiency water pumping system. In the design of the multi-stage sleeve 6, each sleeve 6 is elastically connected to the cavity wall 7 via its built-in slider 8 and spring 9. The slider 8 is also fixedly connected to the sleeve 6 immediately below it. It is worth noting that the diameter of these sleeves 6 decreases gradually from top to bottom, and the bottom of the lowest sleeve 6 is fixed with a rubber pad 10. The inner wall of each sleeve 6 is filled with sound-insulating material.

[0029] The pumping system is securely mounted on the power output shaft of the motor 4, and uses a precision gear transmission device to drive the impeller pump 13 to operate efficiently.

[0030] A water storage tank 15 is mounted on top of the main body of the drilling machine 1. The water inlet port of the impeller pump 13 is sealed to the bottom of the water storage tank 15, while the water outlet port extends into the inside of the sleeve 6. In addition, multiple support structures are provided on the inner wall of the top of the sleeve 6. Each of these support structures is connected to a nozzle 19. All nozzles 19 are connected to the water outlet port of the impeller pump 13, forming a complete water jet system.

[0031] During operation: First, move the drilling machine 1 to the designated position, then turn on the motor 4 switch. The motor 4 then drives the drill bit 5 to rotate. Next, the cylinder 3 starts, driving the crossbeam 2 to descend, causing the drill bit 5 to contact the ground and gradually penetrate deeper for drilling. During the drilling process, the sleeve 6 fits tightly against the ground, forming a closed space. As the hole deepens, the movement of the sleeve 6 causes the slider 8 to move accordingly, thus contracting the spring 9 to ensure that the sleeve 6 remains closed, without hindering the continuous drilling operation.

[0032] Meanwhile, the rotation of the output shaft of motor 4 drives the impeller pump 13 to rotate via gear transmission, drawing water from the water tank 15 into the impeller pump 13, and then delivering it through the outlet pipe to multiple nozzles 19 for water spraying. The water spraying serves two purposes: first, to reduce dust in the air, and second, to cool the drill bit 5, preventing severe wear caused by high-temperature operation. Furthermore, the rotation of the output shaft of motor 4 also drives the disc 17 at the upper end of the sleeve 6 to rotate, thereby causing the nozzles 19 to oscillate, further expanding the dust suppression range and improving the dust suppression effect.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
