Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drilling equipment, and in particular relates to a drilling machine for forming holes for slope drainage pipes. Background Art
[0002] In the construction of roads and railways in mountainous and hilly areas, there are usually a large number of excavated sections. The roadbed of the excavated section is formed by excavating the original ground downward along a certain slope (usually a slope of 1:1.5), so that an upward slope is formed on one or both sides of the roadbed. The vertical height of the slope of some excavated sections can be as high as tens of meters. In order to ensure the stability of such high slopes, the cross-section of such high slopes cannot be a continuous slope according to the specifications, but a flat shoulder with a width of about two meters must be set every five meters or so in the vertical height.
[0003] In order to avoid the possibility of landslides in such high slope sections during the rainy season due to excessive water content in the slope soil, many highway and railway designs require the implantation of drainage pipes of a certain density and depth in the slope to help drain the pore water in the soil layer inside the slope, thereby ensuring the stability of the slope. Such drainage pipes are usually arranged in a row above each shoulder. The drainage pipes are usually PVC pipes with several permeable holes drilled in them, with a diameter of about 80mm. Each row of drainage pipes is usually spaced about 3 meters apart and 12 to 18 meters deep. In the cross section, there is a 5% drainage slope with high inside and low outside.
[0004] The original main purpose of the traditional down-the-hole drill was to drill blasting holes, anchor holes, grouting holes and other rock drilling construction in rock formations. Its push, pull and rotation are driven by hydraulic or electric motors, and it needs to be equipped with a high-power air compressor to provide high-pressure air to the front end of the down-the-hole drill bit through the inner cavity of the drill pipe to drive the drill bit to impact and break the rock. The traditional down-the-hole drill is used to complete this kind of drainage pipe implantation operation, and there are the following problems:
[0005] (1) At present, the traditional crawler-type down-the-hole drill rig does not have the ability to crawl on a slope of 1:1.5. Therefore, in order to reach the shoulder of the high slope for operation, a passage must be provided for the drill rig to walk to the shoulder. For sections without such passage conditions, only a detachable simple drill rig can be used, which is carried up the shoulder of the slope by manpower for construction, which is heavy work and inefficient.
[0006] (2) Since the mast of a traditional down-the-hole drill is suspended on an adjustable arm extending from the chassis of the drill, it cannot provide sufficient recoil for drilling, nor can it provide the drill bit with the top force to penetrate the stratum. Therefore, whether it is rock or soil, the penetration of the down-the-hole drill depends on the pneumatic impact drilling power provided by the air compressor. Therefore, no matter what the stratum conditions are, the down-the-hole drill needs to be equipped with an air compressor to operate, which makes the relocation troublesome and increases the cost.
[0007] (3) In loose strata with poor hole formation, the impact drilling with a down-the-hole hammer will cause vibration and disturbance to the surrounding soil. After the drill bit is withdrawn, the hole is prone to collapse, making it impossible to insert the drainage pipe.
[0008] To this end, we propose a working condition-specific drilling rig that can climb up the shoulder of a high slope step by step, and then move along the shoulder of the slope to perform drilling operations, making the implantation of drainage pipes more efficient and cost-effective, and meeting the needs of large-area slope drainage pipe implantation construction in road and railway construction.

[0016] The drill rod adopts a multi-connected structure, the rear end of which is connected to the driving shaft of the drilling rig power head, and the head end is provided with an alloy cutting drill bit; in order to further improve the drilling efficiency, the drill rod is a spiral drill rod, the rod body of the drill rod is provided with spiral blades, and the drill rod is nested with a casing;
[0017] A clamping mechanism for clamping a drill rod or casing, the clamping mechanism consisting of a front clamp arranged at the front end of a drilling rig beam and a rear clamp located between the sliding base and the front clamp; used to ensure the axial stability of the drill rod when the drilling rig power head pushes the drill rod and casing for drilling; preferably, the rear clamp adopts a sliding structure, and its two legs are respectively fixedly mounted on two slide blocks sliding along the drilling rig beam, and the two slide blocks are respectively connected to the sliding base through a connecting member, so that when the sliding base drives the drilling rig power head to push the drill rod and casing, the rear clamp is simultaneously pushed to slide, thereby ensuring that the stroke of the drilling rig power head is not affected by the rear clamp; further, the two connecting members are hydraulic cylinders, thereby realizing dynamic adjustment of the distance between the rear clamp and the drilling rig power head, keeping the clamp in a suitable position, and further enhancing the axial stability of the drill rod and casing jacking.
[0018] The towing mechanism includes a hydraulic winch rotatably mounted on the rear edge of the vehicle body, a steel wire rope is wound around the hydraulic winch, an anchor pile can be pre-buried at the top of the slope of each construction section to fix the upper end of the steel wire rope, and then the hydraulic winch is driven by the hydraulic motor to reel in the steel wire rope to pull the vehicle body upward, or unreel the steel wire rope to release the vehicle body downward for free descent, so that the drilling rig has the ability to crawl on a slope with a slope of 1:1.5.

[0023] The technical effects achieved by the utility model are:
[0024] The utility model is a drilling rig for forming holes for drainage pipes on a slope. When working, an anchor pile can be pre-buried at the top of the slope of each construction section, and a towing mechanism is used for traction, so that the vehicle body can safely crawl upward along the slope under the drive of the crawler chassis to reach each shoulder platform. The utility model can be firmly fixed on the shoulder platform through the setting of the anchor mechanism, which greatly improves the stability of the drilling rig, can adopt a larger jacking force, and improves the drilling efficiency.
[0025] The utility model discloses a drilling rig for forming holes for drainage pipes on a slope. An anchor pile can be pre-buried at the top of the slope of each construction section to fix the upper end of a steel wire rope. Then, a disk body is driven by a hydraulic motor to reel in the steel wire rope to pull a vehicle body upward, or to unreel the steel wire rope to release the vehicle body downward for free decline, so that the drilling rig has the performance of crawling on a slope with a slope of 1:1.5.
[0026] The utility model discloses a drilling rig for forming holes for drainage pipes on a slope. By setting a gantry structure, a drilling rig base on which a drilling rig beam is installed can adjust its angle. At the same time, the cooperation of a transverse slide rail, a longitudinal slide rail and a lifting seat can be utilized to realize the lifting and lowering and lateral movement of the drilling rig base within the inner frame of the gantry, and the position adjustment in four directions is realized. This not only improves the adjustment range of the drilling rig's incident angle, but also allows the drilling rig base to be raised and the drilling rig beam to be tilted as much as possible during transportation. By increasing the angle between the drilling rig beam and the crawler chassis of the vehicle body, the horizontal width of the entire equipment is reduced, thereby improving the overall passability.
[0027] The utility model discloses a drilling machine for forming holes for drainage pipes on slopes, which adopts a spiral drill rod and a casing to work in cooperation, which not only improves the efficiency of drilling holes, but also improves the convenience of laying drainage pipes and improves work efficiency. At the same time, the support of the casing to the soil layer can meet the operation needs of soft soil layers.
[0028] The new drilling rig of the utility model is different from the single hole-making method of the down-the-hole drilling rig. Since it can exert a greater top force on the drill bit, different drilling and planting pipe processes can be used for different soil layers to ensure higher comprehensive construction efficiency and lower cost:
[0029] 1. When working in ordinary soil layers with good porosity, the spiral drilling process is adopted, that is, the drill rod adopts a spiral drill rod, and the front end adopts an alloy cutting drill bit. The drill rig drives the drill rod and the drill bit to rotate while pushing forward, and the drill cuttings are discharged through the spiral. After the hole is formed, the drill rod and the drill bit are withdrawn, and the drainage pipe is manually inserted into the formed hole;
[0030] 2. When working in loose soil layers where it is difficult to form holes, use the spiral drilling process with an outer casing.
[0031] That is, based on the above-mentioned spiral drilling process, the casing is pushed forward synchronously while drilling, and the casing is connected by threads. After the drilling is completed, the casing remains stationary, the spiral drill rod and the drill bit are withdrawn first, and then the drainage pipe is manually sent into place through the inner hole of the casing, and then the casing is withdrawn.
[0032] 3. When working in soil layers with higher hardness or weathered rock layers, the advance rate of spiral drilling is too slow. Just like a down-the-hole drill, an air compressor is connected to use pneumatic impact drilling and spiral slag removal technology. BRIEF DESCRIPTION OF THE DRAWINGS
