Description

Technical Field

[0001] This utility model relates to the technical field of slope reinforcement engineering equipment, and more specifically to a slope protection drilling rig with dual adjustable angle. Background Technology

[0002] Slope reinforcement is an important civil engineering measure aimed at enhancing slope stability, preventing geological disasters such as landslides and collapses, and protecting the safety of residents, buildings, roads, and other structures below the slope.

[0003] One approach to slope reinforcement involves drilling holes to insert anchor bolts into the rock mass, followed by the injection of cement mortar and other bonding materials to ensure a tight bond between the anchor bolts and the surrounding rock.

[0004] Drilling on hillsides requires a drilling rig. ZL202220564222.6 discloses a slope drilling rig for geological disaster control, including a frame. Two racks are fixedly installed on the top of the frame, and the two racks are arranged in parallel. A bracket is slidably connected to one end of the top of the frame, and a fixed frame is fixedly connected to the other end. A power clamp for clamping and rotating the drill rod is fixedly installed on the bracket. Power walkers are provided on both sides of the power clamp. The power walkers are used to mesh with the racks and drive the bracket to move. The power walkers are fixedly connected to the bracket. A through hole for the drill rod to pass through is opened on the fixed frame. A lifting device is fixedly installed on the side of the frame near the fixed frame end.

[0005] The slope drilling rig is hoisted to the designated location to drill holes. It is mainly suitable for slopes with steep slopes and high mountains. However, for slopes with gentle slopes and low mountains, there are the following problems: (1) Natural slopes are not flat and are uneven. Some places even have pits. Not only do you need to insert the drill rod, but you also need to adjust the drilling angle to work. The single operation mode of the slope drilling rig, which can only drill horizontally, is obviously not suitable. (2) No matter how heavy the equipment is, as long as it is hoisted for operation, there will be swaying and instability. In particular, it also needs to drill holes on the slope. Operational stability is the first problem that needs to be solved. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned defects of the existing technology and provide a slope protection drilling rig with dual adjustable angles. First, it adopts a crawler chassis to increase the mobility of slope movement and improve the stability of fixed-point operation. Second, the first angle of the support platform is adjustable, which is convenient for construction personnel to stand and work. Third, the second angle of the drill rod and drill bit is adjustable to adapt to various slope environments and adjust the drilling angle to meet the requirements of the construction drawings. Fourth, the sliding beam distributes the working stress on the drill rod end, improves the strength of the drill rod, meets the conditions for extending the drill rod, and enables it to meet the requirements of working on various uneven cliffs.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: A slope protection drilling rig with dual adjustable angle, comprising a tracked chassis, on which a support platform is mounted. The supporting platform is characterized by having a working platform hinged to it. A pair of lifting cylinders are connected to the opening and closing parts of the working platform and the supporting platform. The working platform is provided with a pair of support columns arranged separately along its length, one in front and one behind. A lifting arm is connected in series between the two support columns. One end of the lifting arm is hinged to the working platform, and a lifting cylinder is provided between the other end of the lifting arm and the working platform. The two support columns support... A sliding beam that slides in cooperation with them, a large compensating cylinder is connected between the sliding beam and one of the supporting columns, a slide rail extending along its length is provided on the sliding beam, a motor seat that slides in cooperation with the slide rail is provided on the slide rail, a first hydraulic motor is provided on the motor seat, a drill rod is spun onto the motor shaft of the first hydraulic motor, a drill bit is spun onto the free end of the drill rod, a sprocket is provided on each of the two free ends of the sliding beam, one of the sprockets is connected to the motor shaft of a second hydraulic motor, a chain forming a closed loop is wound between the two sprockets, and the lower part of the motor seat is fixedly connected to a point of the chain.

[0008] This utility model utilizes a tracked chassis to transport a drilling rig. The tracked chassis moves and drills on uneven mountain slopes, significantly enhancing its mobility and, more importantly, providing a wider contact surface with the slope and better stability. The working platform and support platform are hinged together and fold under the action of a lifting cylinder. The support platform, adapting to the slope's inclination, is also tilted, which would be inconvenient for workers to stand upright. Therefore, the working platform is added for horizontal positioning, facilitating tasks such as changing drill bits, maintenance, anchor bolt installation, and guiding grouting. A sliding beam, also hinged to the working platform and folding under the action of a lifting cylinder, adjusts the drilling angle of the drill rod and drill bit to adapt to various slope conditions and meet the requirements of the construction drawings. The sliding beam distributes the working stress on the drill rod end, increasing its strength and allowing for the extension of the drill rod to accommodate various uneven cliff faces.

[0009] Preferably, a hydraulic winch is provided on the side of the support platform, and the hydraulic winch is located diagonally below the drill bit, that is, the hydraulic winch and the drill bit are staggered in all directions.

[0010] Low slopes can be transported to designated drilling locations by tracked chassis (with their own powertrain), but to ensure stability when working on slopes, fixed-point positioning is also required. The hydraulic winch can both drag and lift the tracked chassis to assist it in moving on the slope, and also serve the purpose of fixed-point positioning and pulling.

[0011] Preferably, a positioning head is provided on one end of the slide beam that extends beyond the working platform, and the positioning head is provided with several gripping teeth.

[0012] The sliding beam moves in tandem with the drill rod towards the cliff. Once it reaches the designated position, the gripping teeth at its front end embed themselves into the nearby rock where the hole is about to be drilled, thus stabilizing the drilling process and protecting the drill rod and drill bit.

[0013] Preferably, there are four gripping teeth arranged in a matrix.

[0014] The main purpose of the gripping teeth is to insert them into the rock and soil to stabilize the entire slide beam and drill rod. Therefore, the number of teeth is neither better the more nor the less the better. Three to eight teeth are the optimal number, and the matrix arrangement is more conducive to the consistency of strength and stability.

[0015] Preferably, the slide beam is located between the two lifting cylinders, that is, the slide beam is staggered from any of the lifting cylinders in all directions.

[0016] The sliding beam folds under the action of the lifting cylinder, forming a hinged opening and closing relationship with the working platform. The sliding beam and the working platform are connected in a line and a surface. The working platform folds under the action of the lifting cylinder, forming a hinged opening and closing relationship with the support platform. The working platform and the support platform are connected in a surface. The overall length of the lifting cylinder does not allow it to be recessed and placed within the entire structure. Its length inevitably means that the cylinder body must penetrate through the working platform. Therefore, there needs to be a gap on the working platform for it to pass through. However, this will cause the sliding beam and other facilities to be placed in an overlapping manner. Therefore, the sliding beam is located between the two lifting cylinders.

[0017] Preferably, a guide ring is sleeved on the end of the drill rod near the drill bit, which slides with the guide ring. The guide ring is mounted on a slide block, which is slidably mounted on the slide rail. A small compensating cylinder is connected between the slide block and the slide beam.

[0018] The guide ring serves to support the drill pipe from the front, enhancing drilling stability and distributing the operational stress on the pipe end to prevent breakage. The guide ring's position can be adjusted using a small compensating cylinder, according to the drill bit's position.

[0019] Preferably, the guide ring is provided with a dust cover that covers the drill bit.

[0020] Dust control is crucial for hillside operations. Whether it's ensuring the safety of workers below or preventing dust pollution in the environment, dust covers are necessary.

[0021] Beneficial effects: (1) This utility model uses a tracked chassis to transport the drilling rig. The tracked chassis moves and drills on uneven mountain surfaces, which greatly enhances its passability. More importantly, it has a wider contact surface with the mountain slope and better stability.

[0022] (2) The working platform and the support platform of this utility model form a hinged opening and closing relationship, and folding motion under the action of the lifting cylinder. The support platform is also tilted on the hillside according to the slope inclination of the track chassis. This makes it inconvenient for construction personnel to stand and work. Therefore, the working platform is added to adjust the horizontal standing position, which is convenient for construction personnel to change drill bits, maintain, lay anchor bolts and guide the grouting.

[0023] (3) The sliding beam of this utility model forms a hinged opening and closing relationship with the working platform, and folds under the action of the lifting cylinder. Its purpose is to adjust the drilling angle of the drill rod and drill bit, adapt to the uneven environment of each slope, and meet the requirements of the construction drawings.

[0024] (4) The sliding beam of this utility model shares the working stress on the end of the drill rod, improves the strength of the drill rod, meets the conditions for extending the drill rod, and enables it to meet the working conditions of various uneven cliffs. Attached Figure Description

Detailed Implementation

[0028] To make the technical means, creative features and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0029] Example: Figure 1As shown, a slope protection drilling rig with dual adjustable angle includes a tracked chassis 1, a support platform 2 is mounted on the tracked chassis 1, a working platform 3 is hinged to the support platform 2, a pair of lifting cylinders 4 are connected to the opening and closing parts of the working platform 3 and the support platform 2, and a hydraulic winch 5 is mounted on the side of the support platform 2. The hydraulic winch 5 is located diagonally below the drill bit, that is, the hydraulic winch 5 and the drill bit are staggered in all directions.

[0030] like Figure 2 As shown, the work platform 3 is equipped with a pair of support columns 6 arranged one in front of the other along its length. A lifting arm 7 is connected in series between the two support columns 6. One end of the lifting arm 7 is hinged to the work platform 3, and a lifting cylinder 8 is installed between the other end of the lifting arm 7 and the work platform 3. A sliding beam 9 is supported by the two support columns 6 and slides with them. A large compensating cylinder 10 is connected between the sliding beam 9 and one of the support columns 6. The sliding beam 9 is located between the two lifting cylinders 4, that is, the sliding beam 9 and any of the lifting cylinders 4 are staggered in all directions.

[0031] A slide rail 11 is provided on the slide beam 9, extending along its length. A motor seat 12 is provided on the slide rail 11, which is slidably engaged with it. A first hydraulic motor 13 is provided on the motor seat 12. A drill rod 14 is spun onto the motor shaft of the first hydraulic motor 13. A drill bit is spun onto the free end of the drill rod 14.

[0032] A sprocket 15 is provided on each of the two free ends of the slide beam 9. One of the sprockets 15 is connected to the motor shaft of a second hydraulic motor 16. A chain 17 forming a closed loop is wound between the two sprockets 15. The lower part of the motor seat 12 is fixedly connected to a point of the chain 17.

[0033] A positioning head 18 is provided on one end of the sliding beam 9 that extends beyond the working platform. The positioning head 18 is provided with several gripping teeth 19. There are four gripping teeth 19, which are arranged in a matrix.

[0034] A guide ring 20 is fitted onto the end of the drill pipe 14 near the drill bit, and the guide ring 20 is mounted on a slide block 21, which is slidably mounted on a slide rail 11. A small compensating cylinder 22 connects the slide block 21 and the slide beam 9. A dust cover 23 is provided on the guide ring 20 to cover the drill bit.

[0035] Work Process: The steel cable of the hydraulic winch is first sent to the mountaintop and secured. Then, the tracked chassis, powered by its own power, together with the hydraulic winch, sends the drilling rig to the designated drilling position. Drilling can proceed step by step from top to bottom, or vice versa. At this point, the support platform and the mountain slope are aligned. The lifting cylinder raises the working platform until it is level. Construction personnel, wearing safety helmets and safety ropes, can then directly access the working platform to begin work. The working platform is pre-positioned with construction tools or anchor bolts. Next, the lifting cylinder raises the sliding beam, and the drilling angle of the drill rod and drill bit is adjusted according to the construction drawings. The large compensation cylinder is activated, pushing the sliding beam towards the hillside, allowing the gripping teeth on the positioning head to embed into the rock mass near the drilling location. Then, the small compensation cylinder is activated, pushing the guide ring to force the dust cover to cover the drilling location. Immediately afterwards, the second and first hydraulic motors are activated. The second hydraulic motor causes the chain to rotate, pulling the motor seat along the slide rail, allowing the drill bit to contact the rock mass under the guidance of the guide ring. The first hydraulic motor causes the drill rod and drill bit to rotate at high speed, which, together with the second hydraulic motor, slowly advances them, thus beginning the drilling process. After drilling is completed, the second hydraulic motor rotates in the opposite direction, pulling the drill bit out of the drilled hole. The construction workers then insert an anchor rod and guide the cement grouting truck, which delivers grouting head from the ground, to grout the hole, ensuring a tight bond between the anchor rod and the surrounding rock mass.
