[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] This utility model is a fully hydraulic tracked drilling rig, which mainly consists of five parts: the main unit, the stabilization mechanism, the operating platform, the tracked vehicle body, and the pump station. These parts are connected by high-pressure hoses and bolts, resulting in a compact structure and high reliability. The entire machine is equipped with a diesel engine for independent movement, enabling long-distance relocation without the need for a power source.

[0025] (I) Main Unit

[0026] The main unit is the core of the drilling rig, serving as the primary mechanism for driving the rotation, feeding, and conveying of the drill string. The basic structure of the main unit is the feed frame. A power head is mounted on the support plate 2 of the feed frame 1. A chuck 4 on the power head can hold the drill rod, driving it to rotate and move forward and backward. A clamp is installed at the front end of the feed frame 1 to hold the drill rod (or drill string), enabling intermittent entry and exit of the drill rod into and out of the hole, and loading and unloading of the drill rod. A conveying cylinder is mounted on the belly of the feed frame 1. The conveying cylinder is fixed to the feed frame using a hinged shaft structure. The piston rod shackle is connected to the support plate via a traction frame, driving the power head to move back and forth, thus achieving the feeding and conveying of the drill rod and drill string. Figure 1 , Figure 2 As shown.

[0027] 1. Feed rack

[0028] The feed frame 1 is the basic component of the main unit, a rectangular box structure with an open top. The upper surface of the front end of the feed frame 1 is used to mount the chuck. A support plate 2 is mounted on the guide rail of the feed frame 1, and the power head is mounted on the support plate 2 for pulling and feeding the drill string and for rotary drilling. A V-shaped wear-resistant block is installed between the support plate 2 and the guide rail to support the sliding of the support plate 2 on the guide rail. The wear-resistant block is a consumable part and will gradually wear thin during use, requiring adjustment and replacement as needed. A roller device is provided at the rear end of the feed frame for easy loading and unloading of drill pipe. (Details follow...) Figure 3 As shown.

[0029] 2. Conveying hydraulic cylinder

[0030] The conveying cylinder 5 is fixed to the feed frame via two disc needle roller bearings and a hinge seat. This cylinder has two installation methods: one with the rod cavity facing forward and the other with it facing backward.

[0031] 3. Power head

[0032] The power head is the main rotary transmission mechanism of the drilling rig, mounted on the support plate 2 of the feed frame 1. The hydraulic motor 14 on the power head is a manually operated variable displacement motor; by adjusting the motor handwheel, the spindle can achieve any speed within the range of 300~1000 rpm, suitable for various geological structures. The maximum output torque of the power head increases as the rotational speed decreases. The power head is a commonly used component of the drilling rig.

[0033] 4. Clamp

[0034] The clamp adopts a normally closed structure. Under the action of the disc spring 4, the clamp moves via the pull rod 8, driving the auxiliary body 7 of the clamp, thereby bringing the two clamping plates 10 on the main body 6 and auxiliary body 7 together to clamp the drill pipe. The clamp includes the main body 6, auxiliary body 7, pull rod 8, and cylinder 9. The cylinder 9 and piston 11 form a hydraulic cylinder. Clamping plates 10 are provided on the opposite inner surfaces of the main body 6 and auxiliary body 7, directly clamping the drill pipe. The piston 11 is fixedly mounted at one end of the pull rod 8, located inside the cylinder 9, and the other end of the pull rod 8 is fixedly connected to the auxiliary body 7. The main body 6 is fixedly connected to the end of the cylinder 9, and the disc spring 4 is placed between the main body 6 and piston 11. Under the action of the disc spring 4, the pull rod 8 drives the auxiliary body 7 of the clamp to move, bringing the two clamping plates 10 on the main body 6 and auxiliary body 7 together to clamp the drill pipe. The clamp is hydraulically driven and is also called a hydraulic clamp.

[0035] To replace the clamping shoes, simply unscrew the two socket head cap bolts securing the shoes, replace them with new shoes, and tighten the bolts. When pressure enters cylinder 9, piston 11 and cylinder 9 generate thrust. Adjusting the inlet oil pressure adjusts the clamping force on the drill string; the greater the compression of the disc spring 4, the greater the clamping force. When the hydraulic pressure acting on piston 11 exceeds the spring force of disc spring 4, piston 11 drives pull rod 8 backward. At this point, under the action of the four cylindrical helical springs, the main body 6 and the auxiliary body 7 of the clamping device separate, and the clamping shoes 10 will no longer be in contact with the drill pipe. (Specific details are as follows...) Figure 4 , Figure 5 As shown.

[0036] The size of the clamp opening is adjustable. To open a larger hole, loosen the handwheel counterclockwise to increase the opening diameter of the clamping jaws and ensure that the rough drill bit passes through smoothly. If the drill rod slips when unscrewing, tighten the handwheel clockwise to reduce the opening diameter.

[0037] The clamp bearing housing is equipped with a bearing, and the inner hole of the bearing can effectively prevent deviation during drilling.

[0038] (II) Pumping Station Section

[0039] The pump station is the power source for the drilling rig, supplying all the hydraulic oil for the rig. It mainly includes an oil tank, motor, and oil pump. The oil tank serves as the storage base for the hydraulic oil, performing functions such as storage, cooling, and filtration. Electrical energy is converted into hydraulic energy through the motor and oil pump. The oil pump is a double gear pump; when the motor rotates, the front pump is used for motor rotation, and the rear pump is used for feeding the large hydraulic cylinder. When the motor stops, the front and rear pumps work together to pull and deliver the drill pipe.

[0040] (III) Control Panel Section

[0041] The control panel mainly includes a motor rotation multi-way valve, a pull-and-feed clamp multi-way valve, and a water system.

[0042] The motor rotation multi-way valve independently controls the forward and reverse rotation of the motor. The feed, clamping, and pull-out multi-way valves are mechanisms that control the operation of the drilling rig. They monitor the movement of the drilling rig.

[0043] The water system is the device that delivers water or emulsion from the pump to the drill bit. It monitors the water pressure at the bottom of the hole.

[0044] 1. Hydraulic system of the drilling rig

[0045] In the hydraulic system of the drilling rig, the electric motor drives the double gear pump to supply oil. The front pump of the double gear pump supplies the hydraulic motor multi-way valve, and the rear pump of the double gear pump supplies the feed multi-way valve of the conveying clamp.

[0046] (iv) Tracked vehicle body

[0047] The tracked vehicle body consists of two main parts: the track assembly and the vehicle body. The track assembly uses steel track plates, which are wear-resistant and have high strength. The vehicle body is fixed to the crossbeam that connects the left and right track plates and is used to fix and mount components such as the main engine, pump station, and control panel.

[0048] (V) Stabilizing the organization

[0049] The stabilization mechanism mainly consists of upper and lower grounding devices, a telescopic rod, and a stabilizing and adjusting hydraulic cylinder. It operates independently, ensuring vehicle stability and convenient and reliable angle adjustment, and offering strong adaptability. The stabilization mechanism is a common component of drilling machinery and is a standard feature.

[0050] This utility model uses a manual variable displacement motor to drive the spindle rotation, offering a wide speed range and stable operation. The drilling rig is hydraulically controlled, ensuring stable operation. Equipped with a tracked chassis, the rig boasts excellent mobility, is easy to relocate, and adapts to various terrains.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
