[0002] Municipal public works refer to various basic infrastructure projects in urban construction, covering transportation facilities, urban water supply and drainage, gas and heat supply, landscaping and urban lighting. They play a crucial supporting role in enhancing the overall function of the city, improving the quality of life of residents, and promoting sustainable urban development.

[0003] A search revealed Chinese Patent Publication No. CN214836181U, which discloses a road drilling device for traffic engineering construction, including a support base. A support screw is fixedly installed inside the support base, and a motor housing is movably installed on the outer wall of the support screw. A drive motor is fixedly installed inside the motor housing, and the output shaft of the drive motor is fixedly connected to a drive shaft via a coupling. A drive gear is fixedly sleeved on the outer wall of the drive shaft. Through the structural design of the support base, support screw, motor housing, drive motor, drive shaft, drive gear, driven gear, nut, and support shaft, the motor housing can move via a threaded connection with the support screw. The self-locking nature of the threaded connection improves the stability of the overall movement, thus avoiding the phenomenon of shaking during drilling that could lead to drilling failure, and improving the overall stability of the drilling operation. However, this device is inconvenient for adjusting the drilling height. Since municipal engineering construction involves a wide range and many types of construction, the required drilling height varies for different projects. The inconvenience of drilling at different heights necessitates that workers lift the entire device, reducing its practicality and failing to meet the user's needs. Utility Model Content

[0008] The moving mechanism includes a sliding groove and a transmission belt. Two sliding grooves are respectively opened on the front and rear sides of the concave plate. A slider is slidably connected to the inner side of each of the two sliding grooves. The same mounting plate is fixedly connected to the adjacent side of the two sliders. A second motor is fixedly connected to the bottom of the mounting plate. A rotating rod is fixedly connected to the output end of the second motor. A support base is fixedly connected to the top left side of the mounting plate. A threaded rod is rotatably connected to the top of the support base.

The top of the fixing plate is fixedly connected to the threaded sleeve.

[0009] The above technical solution enables the drill bit to move forward while drilling, eliminating the need for additional power to drive the drill bit, thus reducing the workload of workers and lowering the operating cost of the device.

[0010] As a further description of the above technical solution:

[0011] A mounting base is fixedly connected to the left end of the rotating rod, and a drill bit is provided at the left end of the mounting base.

[0012] The above technical solution allows for the installation of drill bits via a mounting base, and enables the replacement of different drill bits according to different geological conditions, achieving better drilling results.

[0013] As a further description of the above technical solution:

[0014] An observation window is provided in the middle of the front side of the hollow shell, and the internal size of the limiting groove matches the size of the rack.

[0015] With the above technical solution, users can observe the operation of the device through the viewing window, and the rack will not slide inside the limiting groove.

[0016] As a further description of the above technical solution:

[0017] A base is fixedly connected to the top left side of the interior of the hollow shell, and a light is fixedly connected to the bottom of the base.

[0018] The above technical solution can provide lighting for workers during nighttime construction, enabling the device to be used normally at night.

[0019] As a further description of the above technical solution:

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the first motor drives the worm to rotate. Since the worm wheel meshes with the worm, the worm wheel will drive the gear to rotate through the transmission column. The racks on both sides will then drive the support plate to move towards the middle. The support plate will then drive the fixing clip to move. When the fixing clip moves, it can push the connecting clip upward through the connecting rod. The concave plate will move upward accordingly. When the concave plate moves upward, it will drive the drill bit to move, which can perform drilling work at different heights, improve the practicality of the device, and meet the needs of users.

[0030] 2. In this utility model, the second motor drives the rotating rod to rotate, and the rotating rod drives the drill bit to rotate through the mounting base to start drilling. Since the rotating rod can drive the threaded rod to rotate through the pulley and the transmission belt, and since the threaded sleeve is fixed to the concave plate through the fixing plate, the rotation of the threaded rod will drive the mounting plate to move to the right, so that the drill bit can move to the right while drilling. The drilling work can be completed without the operator moving the device, which reduces the workload of the operator. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a high-efficiency drilling device for municipal public works construction, comprising a hollow shell 1, a first motor 3 fixedly connected to the rear bottom of the hollow shell 1, a groove 4 formed in the middle of the inner bottom end of the hollow shell 1, the output end of the first motor 3 passing through the hollow shell 1 and fixedly connected to a worm gear 5, a transmission column 6 rotatably connected to the middle of the inner bottom end of the groove 4, a worm wheel 7 fixedly connected to the middle of the outer side of the transmission column 6, the worm wheel 7 meshing with the worm gear 5, a gear 8 fixedly connected to the top of the transmission column 6, and limit grooves 9 formed on both the front and rear sides of the inner bottom end of the hollow shell 1, with racks 10 slidably connected inside each of the two limit grooves 9, the racks 10 meshing with the front and rear sides of the gear 8 respectively. Next, support plates 11 are fixedly connected to the top of the two racks 10 on opposite sides. Fixing clips 12 are fixedly connected to the front and rear sides of the top of the two support plates 11. Connecting rods 13 are rotatably connected to the inner sides of multiple fixing clips 12. A concave plate 14 is provided in the upper middle part of the inner side of the hollow shell 1. Connecting clips 15 are fixedly connected to the bottom of the concave plate 14 around its perimeter. The inner sides of multiple connecting clips 15 are rotatably connected to the corresponding connecting rods 13. A moving mechanism 2 is provided in the inner side of the concave plate 14. The moving mechanism 2 is used to facilitate the movement of the drill head when the device is drilling. An observation window 16 is opened in the middle of the front side of the hollow shell 1. The internal size of the limiting groove 9 matches the size of the racks 10.

[0040] Specifically, when using this device, first move it to the predetermined drilling position, then start the first motor 3. The start of the first motor 3 will drive the worm 5 to rotate. Since the worm 5 and the worm wheel 7 are meshed with each other, when the worm 5 starts to rotate, the worm wheel 7 will also rotate. The rotation of the worm wheel 7 will further drive the transmission column 6 to rotate. The rotation of the transmission column 6 will drive the gear 8 to start to rotate. Since the front and rear sides of the gear 8 are meshed with two racks 10 respectively, when the gear 8 rotates, the racks 10 on both sides will also move. The movement of the racks 10 will drive the support plate 11 to move towards the middle position. The movement of the support plate 11 will drive the fixing clip 12 to move towards the middle. During the movement of the fixing clip 12, through the action of the connecting rod 13, the connecting clip 15 will be pushed upward. At this time, the concave plate 14 will also move upward. The upward movement of the concave plate 14 will drive the drill bit 18 to move accordingly. At this time, it is possible to perform precise drilling work on objects of different heights, which improves the practicality of the device and can meet the needs of users.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The moving mechanism 2 includes a slide groove 201 and a transmission belt 209. Two slide grooves 201 are respectively formed on the front and rear sides of the concave plate 14. Slider blocks 202 are slidably connected to the inner sides of both slide grooves 201. A common mounting plate 203 is fixedly connected to adjacent sides of the two sliders 202. A second motor 204 is fixedly connected to the bottom of the mounting plate 203. A rotating rod 205 is fixedly connected to the output end of the second motor 204. A support base 207 is fixedly connected to the top left side of the mounting plate 203. A threaded rod 208 is rotatably connected to the top. Pulleys 206 are fixedly connected to the outer sides of both the threaded rod 208 and the rotating rod 205. The two pulleys 206 are connected by a transmission belt 209. A threaded sleeve 210 is threadedly connected to the right side of the outer wall of the threaded rod 208. A fixing plate 211 is fixedly connected to the top right side of the concave plate 14. The top of the fixing plate 211 is fixedly connected to the threaded sleeve 210. A mounting base 17 is fixedly connected to the left end of the rotating rod 205. A drill bit 18 is provided at the left end of the mounting base 17.

[0042] Specifically, when using this device, the second motor 204 drives the rotating rod 205 to rotate. The rotating rod 205 is connected to the drill bit 18 through its mounting base 17, allowing the drill bit 18 to rotate and begin drilling. Since pulleys 206 are installed on the outer sides of both the rotating rod 205 and the threaded rod 208, and these two pulleys 206 are connected to each other through a transmission belt 209, when the rotating rod 205 starts to rotate, it will drive the threaded rod 208 to rotate through the pulleys 206 and the transmission belt 209. Since the threaded rod 208 is connected to the threaded sleeve 210, and the threaded sleeve 210 is fixed to the concave plate 14 through the fixing plate 211, when the threaded rod 208 rotates, it will move to the right. When the threaded rod 208 moves, it will drive the mounting plate 203 to move to the right through the support base 207, and the drill bit 18 will also move to the right. Thus, the drilling operation can be completed without the need for the operator to move the device, reducing the workload of the operator.

[0043] Reference Figure 1 A base 19 is fixedly connected to the top left side of the hollow shell 1. A light 20 is fixedly connected to the bottom of the base 19. A caster wheel 22 is fixedly connected to the four corners of the bottom of the hollow shell 1. A self-locking clip 23 is provided on the right side of each caster wheel 22.

[0044] Specifically, the lighting lamp 20 can provide illumination for workers during nighttime construction, and the casters 22 can be easily moved. The casters 22 are equipped with a self-locking device to fix the device during drilling operations.

[0045] Reference Figure 1 , Figure 2 and Figure 4 A handle 24 is fixedly connected to the right side of the hollow shell 1, and a protective sleeve 25 is fixedly connected to the outside of the handle 24. A controller 21 is fixedly connected to the top left end of the front side of the hollow shell 1. The controller 21 is electrically connected to the first motor 3 and the second motor 204 respectively.

[0046] Specifically, the device can be easily moved by the handle 24, and the cover 25 allows the operator to push the handle 24 comfortably. The controller 21 can control the operation of the first motor 3 and the second motor 204 respectively. The first motor 3 and the second motor 204 are both MS8012.

[0047] Working principle: When using this device, first move the device to the position where drilling is required, then start the first motor 3. The first motor 3 drives the worm 5 to rotate. Since the worm wheel 7 meshes with the worm 5, when the worm 5 rotates, the worm wheel 7 will drive the transmission column 6 to rotate. The rotation of the transmission column 6 will drive the gear 8 to rotate. Since the two racks 10 mesh with the two sides of the gear 8 respectively, when the gear 8 rotates, the racks 10 on both sides will drive the support plate 11 to move towards the middle. The movement of the support plate 11 towards the middle will drive the fixing clip 12 to move. When the fixing clip 12 moves, it can push the connecting clip 15 upward through the connecting rod 13. At this time, the concave plate 14 will move upward. When the concave plate 14 moves upward, it will drive the drill bit 18 to move, so that drilling work can be performed at different heights.

[0048] Furthermore, when using this device, the second motor 204 drives the rotating rod 205 to rotate, and the rotating rod 205 can drive the drill bit 18 to rotate through the mounting base 17, thus enabling drilling. Since both the rotating rod 205 and the threaded rod 208 are equipped with pulleys 206 on their outer sides, and the two pulleys 206 are connected by a transmission belt 209, when the rotating rod 205 rotates, it will drive the threaded rod 208 to rotate through the pulleys 206 and the transmission belt 209. Since the threaded rod 208 is connected to the threaded sleeve 210, and the threaded sleeve 210 is fixed to the concave plate 14 through the fixing plate 211, when the threaded rod 208 rotates, it will move to the right, and drive the mounting plate 203 to move through the support base 207. This will drive the drill bit 18 to move to the right, and the drilling work can be completed without the operator moving the device.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
