Description

Technical Field

[0001] This utility model relates to the field of building foundation technology, and in particular to a mud splash prevention device for a mixing drilling rig. Background Technology

[0002] Mixing drilling rigs are widely used in construction fields such as foundation reinforcement, soft soil treatment, and geological exploration. During construction, the drill rod usually needs to rotate and mix underground, and the mud is carried into or out of the hole through the drill rod channel. During the reverse pulling of the drill rod, due to the strong adhesion and high fluidity of the mud, it is very easy to be carried out of the ground along with the drill rod, resulting in mud splashing. This not only pollutes the construction site environment and affects the safety of the workers, but may also cause mud coating and blockage of the drilling rig body, transmission mechanism and surrounding equipment, reducing the service life of the equipment and the efficiency of operation and maintenance.

[0003] To reduce mud spill pollution, some construction sites currently use simple splash guards or enclosures for partial shielding. However, most of these structures used in existing technologies are temporary or single-panel covers, which are cumbersome to install, inconvenient to dismantle, and troublesome to use. Moreover, the overall structural strength is low, making it difficult to maintain a stable protective effect under high-intensity continuous operation. In addition, the contact between these devices and the ground is mostly a rigid structure, lacking self-adjustment capability. When the ground is uneven or the orifice openings are uneven, gaps are easily formed between the cover and the ground, causing mud to continue to spill out along the gaps, further weakening the protective effect. The workload of cleaning and site management is large, affecting construction efficiency.

[0004] Furthermore, we disclose a mud splash prevention device for mixing drilling rigs to meet the practical needs of existing technologies, which suffer from cumbersome installation and disassembly, insufficient shielding strength, inability to adapt to uneven terrain, and difficulty in effectively collecting and discharging splashed mud.

[0006] To achieve the above objectives, this utility model provides a mud splash prevention device for a mixing drill, including a mounting frame installed on a bracket, base, or working platform of the drill body. One end of the mounting frame is fixedly connected to a rear cover, and one end of the rear cover is rotatably connected to a front cover via two hinges. Both the front and rear covers have semi-annular cross-sections, and the front and rear covers can form a complete cover that fits over the drill rod on the drill body. The interior of the cover formed by the front and rear covers is equipped with a cleaning module and a discharge module. The cleaning module is used to clean the solidified mud splashed onto the inner walls of the front and rear covers, and the discharge module is used to discharge the mud splashed onto the inner walls of the front and rear covers in a timely manner. The lower ends of the front and rear covers are equipped with ground adaptive components, which are used to prevent mud carried out by the drill rod from splashing out through the gap between the cover and the ground.

[0007] Preferably, a baffle is fixedly connected to the upper end of both the front cover and the rear cover, the baffle is inclined inward, and a connecting block is fixedly connected to the side of both the front cover and the rear cover away from the hinge, and a locking bolt is installed on the two connecting blocks.

[0008] Preferably, the cleaning module includes a connecting plate, with scrapers fixedly connected to both sides of the connecting plate. Limiting grooves are formed at the same height on the upper inner walls of the front cover and the rear cover. A roller is rotatably connected to the upper side of the connecting plate, and the roller is rolled inside the limiting groove.

[0009] Preferably, a limiting frame is fixedly connected to the upper end of the connecting plate, the limiting frame is slidably sleeved on the outside of the baffle in an inverted U shape, and a knob is provided on the outer wall of the limiting frame.

[0010] Preferably, the discharge module includes a guide plate fixedly connected to the lower middle part of the inner wall of the rear cover. The guide plate is inclined, and the outer wall of the guide plate close to the inner wall of the front cover is in contact with the inner wall of the front cover.

[0011] Preferably, a retaining ring is fixedly connected to the inner side of the upper end face of the guide plate, and a mud discharge pipe is fixedly connected to the lower part of the middle of the front cover. The mud discharge pipe is used to discharge the mud guided out by the guide plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. The mud splash prevention device for this mixing drill rig is formed by a rotating connection between the front and rear covers to create an openable cover structure. The cover can completely cover the working area of ​​the drill rod of the mixing drill rig, forming an effective annular closed chamber during the drill rod extraction process. This can completely block the splashing problem caused by mud adhering to the drill rod, prevent mud pollution of the construction site, effectively improve operational safety and environmental cleanliness, and solve the problem of large-scale spray pollution caused by mud being carried out with the drill rod in the existing technology.

[0015] 2. The mud splash prevention device for this mixing drilling rig has a cleaning module inside the cover.

[0027] like Figures 1 to 4 As shown, a mud splash prevention device for a mixing drill includes a mounting frame 4 installed on a bracket, base, or working platform of the drill body. One end of the mounting frame 4 is fixedly connected to a rear cover 3, and one end of the rear cover 3 is rotatably connected to a front cover 1 via two hinges 11. Both the front cover 1 and the rear cover 3 have semi-circular cross sections, and the front cover 1 and the rear cover 3 can form a complete cover that fits over the outside of the drill rod on the drill body. The cover formed by the front cover 1 and the rear cover 3 is equipped with a cleaning module and a discharge module. The cleaning module is used to clean the solidified mud splashed onto the inner walls of the front cover 1 and the rear cover 3, and the discharge module is used to discharge the mud splashed onto the inner walls of the front cover 1 and the rear cover 3 in a timely manner. The lower ends of the front cover 1 and the rear cover 3 are equipped with ground adaptive components, which are used to prevent the mud carried out by the drill rod from splashing out through the gap between the cover and the ground.

[0028] The device mainly includes an openable front cover 1 and a rear cover 3, which are rotatably connected by a hinge 11 and together form a protective cover that is fitted over the drill rod. The upper end of the cover is provided with an inwardly inclined baffle 2 to prevent mud from splashing upwards. The lower end of the cover is provided with a ground adaptive component, which can adapt to uneven ground and seal the gap between the cover and the ground to prevent mud from overflowing. The inside of the cover is provided with a cleaning module and a discharge module. The cleaning module includes a connecting plate 9 with a scraper 10 that can be rotated directly to remove mud adhering to the inner wall. The discharge module includes a guide plate 12 and a mud discharge pipe 7, which can concentrate and guide the mud and discharge it in a timely manner. The overall structure is reasonably designed and has good sealing performance, convenient operation and splash prevention effect, and is suitable for mixing drilling rig construction scenarios in various terrains.

[0029] like Figure 1 As shown, baffles 2 are fixedly connected to the upper ends of the front cover 1 and the rear cover 3. The baffles 2 are inclined inward. Connecting blocks 8 are fixedly connected to the side of the front cover 1 and the rear cover 3 away from the hinge 11. Locking bolts are installed on the two connecting blocks 8.

[0030] After the cover is closed, the inclined baffle 2 can effectively block the upward force of high-pressure mud during the drill rod pulling process, so that some of the impact mud is rebounded to the inner wall of the cover in advance, reducing the risk of mud contamination to the drilling platform. At the same time, the inclined baffle 2 and the cover together form a buffer envelope structure at the upper end, effectively improving the overall protection range. In addition, by setting the connecting block 8 on the side of the front cover 1 and the rear cover 3 away from the shaft connection and using it in conjunction with the locking bolt, the two halves of the cover can be firmly closed, preventing the cover from opening or loosening due to vibration during construction, thus improving the sealing effect and safety of use.

[0031] like Figures 2 to 3 As shown, the cleaning module includes a connecting plate 9, with scrapers 10 fixedly connected to both sides of the connecting plate 9. Limiting grooves 14 are opened at the same height on the upper part of the inner wall of the front cover 1 and the rear cover 3. A roller 15 is engaged and rotatably connected to one side of the upper end of the connecting plate 9. The roller 15 is rolled inside the limiting groove 14. A limiting frame 5 is fixedly connected to the upper end of the connecting plate 9. The limiting frame 5 is slidably sleeved on the outside of the baffle 2 in an inverted U-shape. A knob is provided on the outer wall of the limiting frame 5.

[0032] During operation, mud splashed onto the inner wall of the hood easily solidifies and accumulates. The cleaning module is manually or with auxiliary power pulled by the limiting frame 5, which drives the connecting plate 9 to move along the trajectory of the inner wall of the hood within the limiting groove 14. The scrapers 10 on both sides scrape off the mud layer. The roller 15 rolls in the limiting groove 14, making the entire cleaning process less resistant and smoother, avoiding direct friction with the hood and thus preventing wear. The limiting frame 5 controls the operating position with a knob and limits the vertical displacement of the cleaning module, making it easy to accurately control the cleaning path. This structure has high cleaning efficiency and can quickly remove attached mud without interrupting the operation, extending the service life of the hood and ensuring continuous and stable protective effect.

[0033] like Figures 1 to 2 As shown, the discharge module includes a guide plate 12 fixedly connected to the lower end of the middle of the inner wall of the rear cover 3. The guide plate 12 is inclined. The outer wall of the guide plate 12 is close to the inner wall of the front cover 1. A retaining ring 13 is fixedly connected to the inner side of the upper end face of the guide plate 12. A mud discharge pipe 7 is fixedly connected to the lower end of the middle of the front cover 1. The mud discharge pipe 7 is used to discharge the mud guided by the guide plate 12.

[0034] After the mud on the inner wall of the enclosure is cleaned by the scraper 10 or slides down naturally, it will be concentrated in the area of ​​the guide plate 12. The guide plate 12 is set at an angle to guide the mud to flow along the slope to the bottom of the enclosure, preventing the mud from stagnating and accumulating. The baffle ring 13 is set at the upper end of the guide plate 12 to block the mud. After being guided, the mud is discharged in time through the mud discharge pipe 7 set on the front enclosure 1. It can be connected to a hose for directional drainage or collection, avoiding accumulation, blockage or odor at the bottom of the enclosure, and realizing the rapid drainage of mud and the maintenance of environmental cleanliness.

[0035] like Figure 4 As shown, the ground adaptive component includes a fixed cylinder 6 fixedly connected to the lower ends of the front cover 1 and the rear cover 3. Multiple mounting plates 16 are fixedly connected to the outer wall of the fixed cylinder 6 at even intervals. A telescopic spring 19 is fixedly connected to the lower end of the mounting plate 16. An abutment plate 18 is fixedly connected to the lower end of the telescopic spring 19. A telescopic sealing layer 17 is fixedly connected to one side of the upper end of the abutment plate 18. The upper end of the telescopic sealing layer 17 is fixedly connected to the lower end of the fixed cylinder 6.

[0036] The ground adaptive component is used to solve the gap problem caused by uneven terrain between the lower end of the cover and the ground. The mounting plate 16 is connected to the fixed cylinder 6 under the cover and is connected to the contact plate 18 through the telescopic spring 19. It can float up and down when the construction ground is uneven and automatically conform to the ground surface at different heights. The telescopic sealing layer 17 set on the contact plate 18 is made of flexible material. It can generate elastic deformation after pressing against the ground to further seal the gap and effectively prevent mud from escaping from the bottom of the cover. This structure not only ensures the splash-proof sealing effect, but also has a buffer function, and will not cause additional interference to the drilling operation. It is suitable for construction needs under various complex terrain conditions.
