Description

Technical Field

[0001] The present invention relates to a device and a hoisting method for loading and unloading drill pipes for a drilling rig by hoisting, belonging to the technical field of drill pipe loading and unloading of a drilling rig. Background Technique

[0002] A horizontal directional drilling rig is a construction machine for laying various underground public facilities (pipelines, cables, etc.) without excavating the ground surface. It is widely used in the laying construction of flexible pipelines such as water supply, electricity, telecommunications, natural gas, coal gas, and petroleum. It is suitable for geological conditions such as sandy soil and clay, and is not suitable for areas with relatively high groundwater levels and pebble formations. Most non-hard rock areas in China can be constructed. The working environment temperature is -15°C to +45°C. The horizontal directional drilling technology is a new construction technology that combines the directional drilling technology in the petroleum industry with the traditional pipeline construction method. It has the advantages of fast construction speed, low construction accuracy, and low cost, and is widely used in pipeline laying construction projects such as water supply, gas, electricity, telecommunications, natural gas, and petroleum. The horizontal directional drilling equipment has also developed rapidly in the past ten years and has become an emerging industry in developed countries. Its development trend is towards large-scale and miniaturization, adapting to hard rock operations, self-provided anchoring systems, automatic stacking and extraction of drill pipes, automatic lubrication of drill pipe connections, automatic operation functions such as anti-electric shock systems, ultra-depth guidance monitoring, and wide application ranges. This type of equipment generally applies to steel pipes and PE pipes with a pipe diameter of φ300 to φ1200mm, and the maximum pipe laying length can reach 1500m, adapting to various soil conditions from soft soil to hard rock, and has broad application prospects.

[0003] The drill pipe is a basic component of the drill string and plays a very important role in the horizontal directional drilling technology.

[0004] During the gradual lengthening process of the drill pipe, it is necessary to continuously load the drill pipe. At present, the drilling rig uses manual replacement of the drill pipe. Manually replacing a drill pipe takes about 10 minutes and requires 3 people to cooperate to complete, which is time-consuming and laborious, with a large error in the installation process and relatively large potential safety hazards.

[0005] In order to improve the loading and unloading efficiency, Chinese invention patent 202023319662.5 discloses an automatic drill pipe loading and unloading mechanism for grasping the drill pipe placed on the ground or the drill pipe standby rack and installing it on the power head of the drilling rig, or disassembling the drill pipe on the power head of the drilling rig and placing it on the ground or the drill pipe standby rack. It can reduce the occupied space of the rod storage bin on the drilling rig, and realizes the automation of drill pipe loading and unloading through the oil cylinder, improves safety, saves a large amount of manual labor workload, flexibly cooperates with various drilling rigs, realizes various state control and adjustment, and is not limited by the drill pipe size at the same time. It is an independent mechanism and does not need to rely on the drilling rig, so it does not increase the design difficulty of the structure of the drilling rig itself.

[0006] However, since the positions of the drill pipes on the ground or on the drill pipe spare rack are different, when the automatic drill pipe loading and unloading mechanism grabs the drill pipes, it is necessary to adjust the distance of grabbing to adapt to the drill pipes at different positions, or the drill pipes on the ground or on the drill pipe spare rack need to be manually placed at the designated position one by one. The power structure is complex and the operation difficulty is great. Summary of the Invention

The remaining drill pipes are still sequentially located on the loading and unloading movable beam 19 at the rear end of the loading and unloading movable plate 22. When loading again, press the reset pedal 10 to continue the conveyance.

[0097] When unloading the rod, by means of the hoisting component of the loading and unloading rod, the inclination of the loading and unloading movable beam 19 is adjusted with the front lifting ear 21 and the rear lifting ear 20, and the rear end is lower than the front end. Place the drill pipe at the front end of the loading and unloading movable plate 22, and the placed drill pipe rolls into the rear of the loading and unloading movable beam 19 due to gravity and is arranged in sequence.

[0098] The device for the loading and unloading rod of the drilling rig according to the present invention can sequentially place the drill pipes at fixed positions, facilitating the grasping by the automatic drill pipe loading and unloading mechanism. It relies on gravity to passively roll back and forth without power.

[0099] Herein, the adaptation of the movable main body to the base main body means that the movable main body is detachably arranged on the base main body, and specifically, it can be formed by the detachable connection between the lower round steel support 2 and the upper round steel support 15.
