Description

Technical Field

[0001] This utility model relates to the technical field of cliff reinforcement engineering equipment, and more specifically to a hoisting platform type high-altitude cliff drilling rig. Background Technology

[0002] The main purpose of cliff reinforcement projects is to improve the structure's resistance to earthquakes, wind, and fire, enhance its ability to withstand natural disasters, reduce the damage caused by disasters, and protect people's lives and property.

[0003] One approach to cliff 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 into cliff faces 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 can also be hoisted up, which is suitable for high-altitude cliff work, but it has the following problems: (1) No matter how heavy the equipment is, as long as it is hoisted up in the air, it will be unstable, especially since it needs to drill holes in the cliff. If it is unstable, it will easily damage the drill rod or the hole; (2) It is not easy to hoist it up to the air once, and it is very costly. If it is only to complete the drilling work, it is somewhat wasteful. Afterwards, another hoisting and anchoring mechanism is needed, and the work efficiency is not high when working together; (3) The cliff is not flat, but uneven, and some places even have large pits, so a long drill rod needs to be inserted. If the drill rod is too long, it may break if it encounters great resistance. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned defects of the existing technology and provide a hoisting platform-type high-altitude cliff drilling rig with a wide operating range, which can meet the drilling operations of cliffs with any unevenness and large height difference. It has strong stability for high-altitude drilling operations, and the working platform can also be used to stand people and place tools or anchor materials. Construction personnel can carry out anchoring and grouting guidance in one step, thus improving the efficiency of cliff reinforcement work.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a hoisting platform type high-altitude cliff drilling rig, characterized in that it includes a rectangular working platform, with a hoisting ring respectively set at each of the four corners of the working platform, and a hoisting steel cable connected to each hoisting ring. The four hoisting steel cables converge upward to the center to form a hoisting knot. The working platform is provided with a pair of support columns arranged separately along their length, one in front of the other. A sliding beam that slides with them is supported on the two support columns. A large compensating hydraulic cylinder is connected between the sliding beam and one of the support columns. One end of the sliding beam extends... A positioning head is provided at the end outside the working platform. The positioning head is provided with several gripping teeth. A slide rail is provided on the slide beam, extending along its length. A motor seat is provided on the slide rail, which slides and engages with it. 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 slide 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. The lower part of the motor seat is fixedly connected to a point of the chain.

[0008] This utility model features a crossbeam that works in conjunction with the drill rod to advance towards the cliff face. Upon reaching the designated position, its front-end gripping teeth embed themselves into the nearby rock mass where drilling will take place, stabilizing the drilling process. Furthermore, the crossbeam distributes the operational stress on the drill rod end, increasing its strength and allowing for the extension of the drill rod to accommodate various uneven cliff surfaces. In addition, the work platform provides a space for personnel to stand, place tools or anchor materials, and facilitates tasks such as drill bit replacement, maintenance, anchor installation, and grouting guidance—all completed in one step, significantly improving the efficiency of cliff reinforcement work.

[0009] 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.

[0010] 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.

[0011] Preferably, the guide ring is provided with a dust cover that covers the drill bit.

[0012] Dust control is crucial for high-altitude operations. Whether it is to ensure the safety of construction workers below or to prevent dust pollution in the environment, it is necessary to install dust covers.

[0013] Preferably, the working platform is provided with a horizontal rail arranged along its length, the horizontal rail is arranged in a straight line with two supporting columns, a support column is provided between the horizontal rail and the sliding beam, the upper end of the support column is fixedly connected to the sliding beam, and a pulley is provided at the lower end of the support column, the pulley riding on the horizontal rail.

[0014] To make the reciprocating motion of the sliding beam smoother and its straight-line movement more stable, an additional support column is added. However, this support column needs to be supported by pulleys, so as not to add any more friction to the sliding beam.

[0015] Preferably, a safety guardrail is provided on each of the two sides along the length of the work platform.

[0016] The work platform is not only for people to stand on, but also for placing tools or anchor materials. Safety railings are essential and can be used to secure the safety ropes of operators, as well as to secure tools and other items.

[0017] Preferably, a reinforcing flange is provided on each of the two sides of the working platform in the width direction, and each reinforcing flange is provided with a number of connecting holes arranged at equal intervals along its length direction.

[0018] Sometimes, to improve work efficiency, multiple drilling rigs are used for high-altitude drilling at the same time. As long as the load capacity of the crane is large enough, multiple drilling rigs can be lifted at the same time to work synchronously. In order to improve the coordination of these drilling rigs, they are connected together by bringing adjacent reinforcing flanges together and screwing in enough bolts and nuts into the connecting holes.

[0019] Preferably, a stacking column running through each of the four corners of the work platform is provided, with a positioning pin at the top of each stacking column and a positioning slot at the bottom of each stacking column.

[0020] The drilling rig and work platform occupy a large area, making storage a significant issue, especially for equipment manufacturers or engineering companies that may have multiple such machines. Considering their relatively low height, stacking columns are added to stack them up, saving storage space. The positioning slots of the previous machine and the positioning pins of the next machine work together to form a stable stack.

[0021] Preferably, the working platform consists of a supporting frame and several pieces of supporting steel mesh laid on the supporting frame.

[0022] The supporting frame is mainly a base frame welded from high-strength metal steel, and then a steel mesh is laid on it to form a work platform where people can stand and place tools or anchor materials. Construction workers can wear safety helmets and hang safety ropes to go directly to the work platform to carry out anchoring and grouting guidance, which can be done in one step and improve the efficiency of cliff reinforcement work.

[0023] Beneficial effects: This utility model has a wide operating range, meeting the requirements for drilling operations on cliffs with uneven surfaces and large height differences. It provides strong stability for high-altitude drilling operations, and the working platform can also be used to stand people and place tools or anchor materials. Construction personnel can perform tasks such as changing drill bits, maintenance, anchoring, and grouting guidance in one step, improving the efficiency of cliff reinforcement work.

[0029] Example 1: Figure 1 As shown, a hoisting platform type high-altitude cliff drilling rig includes a rectangular working platform 1, which consists of a supporting frame and several pieces of supporting steel mesh laid on the supporting frame.

[0030] like Figure 2 As shown, a lifting ring 2 is set at each of the four corners of the working platform 1. A lifting steel cable 3 is connected to each lifting ring 2. The four lifting steel cables 3 converge upward to the center to form a lifting knot 4. The lifting knot 4 is connected to the anti-detachment hook of the crane.

[0031] A safety guardrail 5 is installed on each of the two sides along the length of the work platform 1.

[0032] like Figure 3 As shown, the work platform 1 is provided with a pair of support columns 10 arranged one in front of the other along its length. The two support columns 10 support a sliding beam 11 that slides with them. A large compensating oil cylinder 12 is connected between the sliding beam 11 and one of the support columns 10.

[0033] A horizontal rail 28 is provided on the working platform 1 along its length. The horizontal rail 28 is arranged in a straight line with two supporting columns 10. A support column 13 is provided between the horizontal rail 28 and the sliding beam 11. The upper end of the support column 13 is fixedly connected to the sliding beam 11. A pulley 14 is provided at the lower end of the support column 13, and the pulley 14 sits on the horizontal rail 28.

[0034] A positioning head 15 is provided on one end of the slide beam 11 that extends beyond the working platform, and four gripping teeth 16 are provided on the positioning head 15.

[0035] A slide rail 17 extending along its length is provided on the slide beam 11. A motor seat 18 slidingly engages with the slide rail 17. A first hydraulic motor 19 is provided on the motor seat 18. A drill rod 20 is shafted onto the motor shaft of the first hydraulic motor 19. A drill bit is shafted onto the free end of the drill rod 20. A sprocket 21 is provided on each of the two free ends of the slide beam 11. One of the sprockets 21 is connected to the motor shaft of a second hydraulic motor 22. A chain 23 forming a closed loop is wound between the two sprockets 21. The lower part of the motor seat 18 is fixedly connected to a point of the chain 23.

[0036] A guide ring 24 is fitted onto the end of the drill pipe 20 near the drill bit, and the guide ring 24 is mounted on a slide block 25, which is slidably mounted on a slide rail 17. A small compensating cylinder 26 connects the slide block 25 and the slide beam 11. A dust cover 27 is provided on the guide ring 24 to cover the drill bit.

[0037] Example 2: A reinforcing flange 6 is provided on both sides of the working platform 1 in the width direction. Each reinforcing flange 6 is provided with ten connecting holes 7 arranged at equal intervals along its length direction.

[0038] The rest is the same as in Example 1.

[0039] Example 3: A stacking column 8 is also provided at each of the four corners of the work platform 1, running through it from top to bottom. Each stacking column 8 has a positioning pin 9 at its upper end and a positioning slot at its lower end.

[0040] The rest is the same as in Example 1.

[0041] Work process: Construction workers wearing safety helmets and safety ropes go directly to the work platform to work. The work platform is pre-positioned with construction tools or anchor materials. After the anti-detachment hook of the crane is stably connected to the hoisting joint, the entire working platform is lifted to the designated height of the cliff edge. Then, it is slowly moved towards the cliff and, after maintaining the designated distance, the large compensation cylinder is activated to push the sliding beam towards the cliff, allowing the gripping teeth on the positioning head to penetrate 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 hydraulic motor and the first hydraulic motor are activated. The second hydraulic motor causes the chain to rotate, which pulls the motor seat to move on the slide rail, so that the drill bit contacts the rock mass under the guidance of the guide ring. The first hydraulic motor makes the drill rod and drill bit rotate at high speed, and together with the second hydraulic motor, they slowly move forward to begin drilling. 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 insert an anchor rod and then guide the cement grouting head delivered from the ground to grout the hole, so that the anchor rod is tightly bonded to the surrounding rock mass.
