Description

Technical Field

[0001] The present invention relates to the technical field of drilling, and more specifically, to a drilling device for building construction foundation. Background Art

[0002] The foundation drilling equipment in building construction is a key machine used to drill holes on the ground or underground for work such as pile foundation engineering, geological exploration, and groundwater extraction.

[0003] When using the drilling equipment for foundation drilling operations, the rotation of the equipment during drilling will cause dust to fly, which not only affects the health of the operator, but also makes the screening system of the drilling equipment prone to blockage due to long-term operation. Traditional foundation drilling equipment usually only relies on a simple vacuum cleaner to handle dust (for example, Chinese Patent Publication No. CN219281679U discloses a drilling device for building foundation, and CN116752896A relates to a building construction drilling method and its device). Currently, when the drilling equipment is in use, there are the following defects: First, when the screening system is blocked, a cleaning brush is used to clean the screening plate. However, keeping the filtering system static and using a brush cleaning method often cannot ensure that all dust in the screening system is completely removed, especially in hard-to-reach corners, and over time, it will still lead to the blockage problem of the screening system; Second, when drilling the building construction foundation, a dust collection system is usually installed on the drilling equipment to clean the dust in the drilling area. However, this simple dust removal method can only handle the dust around the drill bit and is difficult to effectively prevent the problem of dust flying everywhere. The construction site may still face the situation of poor dust control. In view of this, we propose a drilling device for building construction foundation. Summary of the Invention

[0004] The purpose of the present invention is to provide a drilling device for building construction foundation to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides a drilling device for building construction foundation, including a mobile chassis and a sliding bracket assembled on the top surface of the mobile chassis. A drilling mechanism is fixedly installed on the bottom surface of the sliding bracket, and a dust removal mechanism for handling dust is arranged on one side of the mobile chassis away from the sliding bracket; A cleaning mechanism for filtering dust is arranged outside the sliding bracket. When the drilling mechanism moves, the generated moving force will be transmitted to the cleaning mechanism, enabling the cleaning mechanism to adopt a self-vibrating cleaning method during the moving process, and the drilling mechanism extends into the building construction foundation, causing the cleaning mechanism to gradually approach the surface of the building construction base.

[0006] As a further improvement of the technical solution, a moving wheel body for moving the device is fixedly installed on the bottom surface of the moving chassis. A chute is provided on one side of the sliding bracket close to the drilling mechanism to assist the movement of the drilling mechanism, and a top plate is fixedly connected to the top of the sliding bracket.

[0007] As a further improvement of the technical solution, the drilling mechanism includes a hydraulic lifting rod fixedly connected to the bottom surface of the top plate. A driving motor is fixedly installed at the bottom of the hydraulic lifting rod, and a sliding block is fixedly connected to one side of the driving motor. The sliding block is adapted to the chute. The output end of the driving motor is splined with a sliding rod, and a drill rod is fixedly connected to the bottom of the sliding rod.

[0008] As a further improvement of the technical solution, the dust removal mechanism includes a collection bin fixedly installed on one side of the top of the moving chassis. A discharge port is connected through one side of the collection bin to centrally discharge the collected dust from the device. A dust suction pump is fixedly installed on the front of the dust removal mechanism. The output end of the dust suction pump is communicated with the collection bin, and the input end of the dust suction pump is communicated with a delivery pipe.

[0009] As a further improvement of the technical solution, the cleaning mechanism includes a protective sleeve slidably connected to the outer wall of the sliding rod. A delivery cavity is connected through the top of one side of the protective sleeve, and the top of the delivery cavity is communicated with the input end of the delivery pipe.

[0010] As a further improvement of the technical solution, stabilizing rods are fixedly connected to both sides of the protective sleeve, and one end of each stabilizing rod is fixedly connected to the sliding bracket. A screening plate is slidably connected inside the protective sleeve. Elastic blocks are fixedly connected to both sides of the screening plate. Moving grooves are provided on both sides inside the protective sleeve for the movement of the screening plate, and raised blocks are fixedly installed inside the moving grooves.

[0011] As a further improvement of the technical solution, pulling rods are fixedly connected to both sides of the top of the screening plate, and the tops of the pulling rods are connected to the top of the driving motor.

[0012] As a further improvement of the technical solution, the pulling rods are slidably connected to the protective sleeve. By moving the pulling rods up and down, the screening plate is driven to move up and down and generate vibrations, thereby realizing the self-vibration cleaning of the screening plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this building construction foundation drilling device, during drilling, the cleaning mechanism moves downward along with the drilling mechanism, enabling the cleaning mechanism to effectively block near the ground to ensure the protection range. Under the action of the adsorption force, the dust is reduced from drifting outward. When it is necessary to clean the covered dust, the drill rod reciprocates telescopically to drive the cleaning mechanism to reciprocate up and down accordingly. During the up and down movement, the screening plate vibrates, which on the one hand helps to shake off the dust, avoiding the situation where the dust in the dead corners cannot be affected by the shaking force and improving the cleaning effect. Different from the existing method of statically brushing the dust with structures such as brushes, which causes the dust in the dead corners to not be affected by the acting force and fall off. On the other hand, the suction force generated by the dust removal mechanism acts on the filter screen again, enabling the dust to be subjected to multi-directional forces, further improving the cleaning effect, and at the same time, the dust can be adsorbed to avoid the secondary floating of dust and harm to the environment.

[0014] 2. In the building construction foundation drilling equipment, the dust removal mechanism sucks the dust generated by drilling into the collection bin through the suction pump via the conveying pipe, efficiently collecting the dust and reducing the dust pollution at the construction site. At the same time, the protective sleeve of the cleaning mechanism is slidably connected to the outer wall of the sliding rod, and the screening plate vibrates and cleans itself inside the protective sleeve, which can effectively filter the dust and convey the filtered dust to the dust removal mechanism through the conveying cavity, forming a complete dust treatment closed-loop and improving the dust treatment efficiency.

[0015] In addition to the purposes, features and advantages described above, the present invention has other purposes, features and advantages. The following will refer to the drawings to further elaborate on the present invention in detail. Brief Description of the Drawings

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0019] Please refer to Figure 1 - Figure 8 As shown in the figure, this embodiment provides a building construction foundation drilling device, including a mobile chassis 100 and a sliding bracket 101 assembled on the top surface of the mobile chassis 100. A drilling mechanism 200 is fixedly installed on the bottom surface of the sliding bracket 101. On one side of the mobile chassis 100 away from the sliding bracket 101, there is a dust removal mechanism 300 for treating dust; A cleaning mechanism 400 for filtering dust is provided outside the sliding bracket 101. When the drilling mechanism 200 moves, the generated moving force will be transmitted to the cleaning mechanism 400, enabling the cleaning mechanism 400 to adopt a self-vibrating cleaning method during the moving process, and the drilling mechanism 200 extends into the building construction foundation, causing the cleaning mechanism 400 to gradually approach the surface of the building construction base.

[0020] When the present invention drills the foundation, on the one hand, a large amount of dust generated during the drilling process becomes a major problem at the construction site. These dusts drift wantonly, seriously polluting the construction environment, sharply reducing the air quality at the construction site, not only affecting the normal operation vision of construction workers, but also possibly causing construction workers to inhale too much dust, leading to various respiratory diseases and seriously threatening their physical health. Therefore, the dust removal mechanism 300 sucks the dust generated by drilling through the conveyor pipe 302 into the collection bin 301 by a suction pump, efficiently collecting the dust and reducing the dust pollution at the construction site. At the same time, the protective sleeve 401 of the cleaning mechanism 400 is slidably connected to the outer wall of the sliding rod 204, and the screening plate 403 vibrates and cleans inside the protective sleeve 401, which can effectively filter the dust and convey the filtered dust to the dust removal mechanism 300 through the conveyor cavity 402, forming a perfect dust treatment closed loop and improving the dust treatment efficiency; On the other hand, since the rotation drilling of the equipment will cause dust to fly, which not only affects the health of the operator, but also makes the screening system of the drilling equipment prone to blockage due to long-term operation. Traditional foundation drilling equipment usually relies only on a simple vacuum cleaner to handle dust. When the screening system is blocked, a cleaning brush is used to clean the screening plate. However, this static cleaning method often cannot completely remove all the dust in the screening system, especially in hard-to-reach corners. Over time, it will still cause blockage problems in the screening system. Therefore, during drilling, the cleaning mechanism 400 moves downward with the drilling mechanism 200, so that the cleaning mechanism 400 can effectively block near the ground to ensure the protection range. Under the action of the adsorption force, the outward dispersion of dust is reduced. When it is necessary to clean the covered dust, the drill rod 205 reciprocates telescopically, driving the cleaning mechanism 400 to reciprocate up and down. During the up and down movement, the screening plate 403 is shaken. On the one hand, it is beneficial to shake off the dust, avoiding the dust in the dead corners from not being affected by the shaking force and improving the cleaning effect. Different from the existing static brushing of dust by structures such as brushes, which causes the dust in the dead corners to not be affected by the acting force and fall off. On the other hand, the suction force generated by the dust removal mechanism 300 acts on the filter screen again, so that the dust is subjected to multi-directional forces, further improving the cleaning effect, and the dust can be adsorbed to avoid the secondary floating of dust and harm to the environment.

[0021] On this basis, the specific structure is disclosed in detail: To realize the up and down movement of the drilling mechanism 200, as Figure 2 shown, a moving wheel body for moving the equipment is fixedly installed on the bottom surface of the moving chassis 100. A chute is provided on one side of the sliding bracket 101 close to the drilling mechanism 200 to assist the movement of the drilling mechanism 200. And the top of the sliding bracket 101 is fixedly connected with a top plate 102. The drilling mechanism 200 includes a hydraulic lifting rod 201 fixedly connected to the bottom surface of the top plate 102. A driving motor 202 is fixedly installed at the bottom of the hydraulic lifting rod 201. And a sliding block 203 is fixedly connected to one side of the driving motor 202. The sliding block 203 is adapted to the chute. The output end of the driving motor 202 is spline-connected with a sliding rod 204. And the bottom of the sliding rod 204 is fixedly connected with a drill rod 205; Therefore, in the drilling mechanism 200, the hydraulic lifting rod 201 fixed to the bottom surface of the top plate 102 can flexibly adjust the drilling depth according to the construction requirements. By controlling the telescopic movement of the hydraulic lifting rod 201, the drill rod 205 can accurately reach soil layers or rock layers at different depths, meeting the diverse requirements for the foundation drilling depth and improving the adaptability of the equipment to different construction scenarios.

[0022] To realize the treatment of dust during drilling, as Figure 1As shown in the figure, the dust removal mechanism 300 includes a collection bin 301 fixedly installed on one side of the top of the mobile chassis 100. One side of the collection bin 301 is connected with a discharge port in a penetrating manner, which is used to centrally discharge the collected dust from the equipment. A dust suction pump is fixedly installed on the front of the dust removal mechanism 300. The output end of the dust suction pump is communicated with the collection bin 301, and the input end of the dust suction pump is communicated with the conveying pipe 302; Therefore, the dust suction pump can actively extract the dust generated by drilling, quickly introduce the dust into the collection bin 301 through the conveying pipe 302, greatly reduce the dust diffusion at the construction site, significantly improve the air quality of the construction environment, reduce the risk of construction workers inhaling dust, protect their physical health, and the discharge port of the collection bin 301 can centrally process the dust, which is convenient for subsequent unified transportation and disposal, avoiding secondary dust pollution. The entire dust removal mechanism 300 effectively improves the dust handling capacity of the equipment, ensures the continuous and stable operation of the equipment, reduces equipment failures caused by dust influence, extends the service life of the equipment, and at the same time reduces the equipment maintenance cost and frequency.

[0023] To achieve the filtration of dust by the cleaning mechanism 400 and its own cleaning, as Figure 3 - Figure 7 As shown in the figure, the cleaning mechanism 400 includes a protective sleeve 401 slidably connected to the outer wall of the sliding rod 204. The top of one side of the protective sleeve 401 is connected with a conveying cavity 402 in a penetrating manner, and the top of the conveying cavity 402 is connected with the input end of the conveying pipe 302 in a penetrating manner. Both sides of the protective sleeve 401 are fixedly connected with stabilizing rods, and one end of the stabilizing rod is fixedly connected with the sliding bracket 101. A screening plate 403 is slidably connected inside the protective sleeve 401. Elastic blocks 404 are fixedly connected to both sides of the screening plate 403. Moving grooves 405 are opened on both sides inside the protective sleeve 401 for the movement of the screening plate 403, and a protruding block 406 is fixedly installed inside the moving groove 405. Pulling rods 407 are fixedly connected to both sides of the top of the screening plate 403. The top of the pulling rod 407 is connected to the top of the driving motor 202. The pulling rod 407 is slidably connected with the protective sleeve 401. By moving the pulling rod 407 up and down, the screening plate 403 is driven to move up and down and generate vibrations, thereby realizing the vibration cleaning of the screening plate 403 itself; On the one hand, the protective sleeve 401 wraps the sliding rod 204, and the screening plate 403 inside it can preliminarily screen the dust entering with the air flow. During the drilling process, the dust raised from the drill rod 205 is sucked by the dust suction pump and enters the conveying cavity 402 through the protective sleeve 401. During this process, the screening plate 403 can intercept larger particles of dust and prevent them from entering the subsequent conveying pipe 302 and the dust removal mechanism 300, improving the filtration accuracy of the dust, helping to purify the air entering the dust removal system, and enabling the dust removal mechanism 300 to handle dust more efficiently; On the other hand, the pulling rod 407 is connected to the top of the driving motor 202. When the driving motor 202 works, the moving force is transmitted to the pulling rod 407, driving the screening plate 403 to move up and down and vibrate. The elastic blocks 404 on both sides of the screening plate 403 interact with the protruding blocks 406 in the moving slots 405, enhancing the vibration effect, realizing the automatic vibration cleaning of the screening plate 403. This avoids the blockage of the screening plate 403 due to dust accumulation, always maintains good filtering performance, reduces the workload and frequency of manual cleaning, reduces the maintenance cost, and at the same time ensures that the cleaning mechanism 400 can continuously and stably play its role during the long-term operation of the equipment.

[0024] Working principle of the present invention: The moving wheel body installed on the bottom surface of the moving chassis 100 moves the equipment to the construction site. The top plate 102 of the sliding bracket 101 provides support for the drilling mechanism 200. The hydraulic lifting rod 201 extends, driving the driving motor 202 and the drill pipe 205 below to descend to a suitable position. The sliding block 203 on one side of the driving motor 202 slides in the chute opened on the side of the sliding bracket 101 close to the drilling mechanism 200, assisting the stable movement of the drilling mechanism 200; When the drilling mechanism 200 moves, the driving motor 202 will move up and down. The driving motor 202 drives the pulling rod 407 to move up and down. The pulling rod 407 drives the screening plate 403 to move up and down and vibrate in the moving slot 405 inside the protective sleeve 401. The elastic blocks 404 on both sides of the screening plate 403 interact with the protruding blocks 406 in the moving slot 405, causing the screening plate 403 to vibrate when moving, realizing the vibration cleaning of the screening plate 403 itself. At the same time, the conveying cavity 402 connected through the top on one side of the protective sleeve 401 is connected to the input end of the conveying pipe 302, and the filtered dust is conveyed to the dust removal mechanism 300; The driving motor 202 is started, and the sliding rod 204 and the drill pipe 205 at the bottom are driven to rotate through spline connection for drilling operations. The dust suction pump on the front of the dust removal mechanism 300 is started, and the dust generated by drilling is sucked into the collection bin 301 through the conveying pipe 302. The discharge port on one side of the collection bin 301 can centrally discharge the collected dust from the equipment.
