Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, and in particular to a deep well crawler electric drive drilling rig and a transportation method thereof. Background Art

[0002] Deep well crawler drilling rigs are mainly used in various deep hole drilling construction such as coal bed gas drilling, deep geothermal holes, oil exploration and development, grouting holes, and detection wells. They can use air down-the-hole hammer drilling, mud drilling, and can be used with rope coring and other construction techniques. At present, this type of drilling rig products on the market are divided into two forms: diesel drive and motor drive (electric drive is equipped with a low-power diesel power module - responsible for crawler walking), but there are the following disadvantages: 1. The whole machine is relatively long when transported. Due to structural requirements, the drill mast on the vehicle is much longer than the crawler chassis on the vehicle. In addition, the whole machine is heavy when transported. If the crawler is used to move the machine, there is a great risk of rollover due to the high center of gravity of the upper and lower trucks. 2. As the relevant national road transport regulations require that the height of cargo transportation should not exceed 4.5 meters, a special flatbed truck with a platform height of 300mm or 400mm is required for transportation. The height requirement of the chassis of the transportation vehicle is relatively strict, and the transportation cost is relatively high; 3. At present, most of the driller rooms at the wellheads of crawler drilling rigs on the market need to dismantle the relevant hydraulic or electrical control pipelines every time they are moved, which is cumbersome and reduces the service life of the relevant connectors. At the same time, the transportation cost and disassembly and assembly cost are increased during the relocation and well site layout. 4. The electric-driven crawler drilling rig uses two power modules to work independently. The main motor power module provides drilling power for the entire hydraulic system of the drilling rig, and the diesel power module provides power for crawler travel. When the equipment is drilling, if the main motor power module fails, the drilling rig will lose drilling power, which can easily lead to drilling accidents such as drill sticking, bringing drilling risks.

[0003] Therefore, there is an urgent need for a deep well crawler electric drive drilling rig and a transportation method that can solve the above-mentioned shortcomings. Summary of the invention

[0004] The purpose of the present invention is to provide a deep well crawler electric drive drilling rig and a transportation method, aiming to solve the technical problems of traditional deep well crawler drilling rigs such as high transportation height of the whole machine, high center of gravity of the whole machine, cumbersome disassembly and assembly of the driller's room, and easy failure of single drilling power.

[0006] As a further improvement of the above solution, the deep well crawler electric drill also includes a driller's room, and the driller's room is rotatably arranged outside the vertical telescopic leg of a leg assembly.

[0007] As a further improvement of the above solution, the driller's chamber is rotatably arranged outside the vertical telescopic leg of a leg assembly through a rotating structure; The rotatable structure comprises a sleeve sleeved on the outer wall of the vertical telescopic leg, and a rotating pile rotatably sleeved outside the sleeve, and the rotating pile is connected to the driller's chamber.

[0008] As a further improvement of the above solution, the driller's room includes a mounting bracket and an operating room body connected to the mounting bracket; The rotary pile is connected to the mounting bracket, and the mounting bracket is also provided with a transport fixing pin shaft. Correspondingly, a pin shaft hole matching the transport fixing pin shaft is provided on the frame platform so as to fix the driller's chamber during transportation.

[0009] As a further improvement of the above scheme, the drilling mast mechanism includes a mast, a wellhead working platform detachably arranged on the mast, and a swivel arm arranged on the side of the mast, and a hydraulic tongs detachably connected to the swivel arm.

[0010] As a further improvement of the above scheme, the transverse telescopic arm includes at least one transverse arm and a transverse telescopic cylinder connected to the transverse arm, the transverse arm is telescopically arranged in the frame platform, the end of the transverse telescopic cylinder away from the telescopic end is fixedly connected to the frame platform, and the telescopic end is arranged to extend into the transverse arm and connected to the transverse arm; Furthermore, a connecting structure is provided at the telescopic end of the transverse arm for connecting the vertical telescopic legs.

[0011] As a further improvement of the above solution, the vertical telescopic legs are vertical oil cylinders, the telescopic ends of the vertical oil cylinders are arranged toward the ground, and the telescopic ends are also hinged with a support for contacting the ground; The driller's chamber is rotatably arranged outside the cylinder barrel of the vertical oil cylinder.

[0012] As a further improvement of the above solution, the motor is arranged at the end of the frame platform away from the driller's room, and is used to provide power for the hydraulic main pump of the hydraulic system of the whole machine; The diesel engine is suspended at the rear end of the frame platform and provides power for the crawler traveling mechanism when traveling; if the motor fails or there is a high power demand condition, the motor power is switched to the diesel engine or the diesel engine power is integrated into the motor to provide drilling power for the drilling rig operation.

[0013] In a second aspect, the present invention further provides a method for transporting a deep well crawler electric drive drilling rig as provided in the first aspect, the steps of which include: S1. Remove the detachable parts on the drilling mast mechanism so that the height and weight of the whole machine are lower than the national road transportation regulations; S2, first control the lateral telescopic arms of the four leg assemblies to drive the vertical telescopic legs to extend outward respectively, and make the center distance of the left and right vertical telescopic legs greater than the width of the transport truck; then control the vertical telescopic legs to prop up the whole machine, so that the net height of the crawler from the ground is greater than the height of the transport truck; S3, the transport truck is poured into the space formed between the crawler track and the ground and is at a designated position; S4, first control the vertical telescopic legs to retract and put away, and place the whole machine on the transport flatbed truck; then control the transverse telescopic arms to retract, so that the width of the whole machine is less than the road width limit specified by the state; Then the transport truck is started to transport the deep well crawler electric drive drilling rig to the designated location, and step S2 is repeated, and the transport truck drives away.

[0014] As a further improvement of the above scheme, in step S4, after the lateral telescopic arm is controlled to retract to the specified position, it is checked and confirmed that the driller's chamber is stored at the head end of the whole machine (with the forward direction as the front as a reference); If the driller's room is not stored in the head end of the whole machine, rotate the driller's room to store it in the head end of the whole machine, and connect it to the frame platform through the transportation fixing pin shaft; If the driller's chamber is stored at the head end of the whole machine, check whether the transport fixing pin connects the driller's chamber to the frame platform to ensure that the driller's chamber cannot be rotated during transportation.

[0015] Since the present invention adopts the above technical solution, the beneficial effects of this application are: 1.

The arrangement of the leg assembly enables the drilling rig to quickly get on and off the transport flatbed, and compared with the traditional way of getting on and off the vehicle (driving the transport flatbed up and down by the crawler walking mechanism), the problem of rollover caused by the high center of gravity of the fuselage can be avoided, so that the method of the present invention of lifting the fuselage by the leg assembly and moving the transport flatbed on and off the vehicle is safer and more convenient. In addition, in order to meet the height, width and weight of the whole machine during transportation and make it comply with national road transportation regulations, in the present invention, by opening two accommodating grooves on the chassis bracket, the chassis crossbeam of the frame platform can be correspondingly arranged in the accommodating grooves, thereby reducing the plane height of the frame platform and the installation height of the power module, thereby effectively reducing the height of the whole machine to meet the height requirements stipulated by national roads; arranging an outrigger assembly on the frame platform, on the one hand, facilitates the up and down transportation of the flatbed truck, and on the other hand, can also reduce the width of the fuselage (by arranging a transverse telescopic arm, the outrigger assembly can be extended during construction to increase the contact range with the ground, without increasing the spacing between the two left and right crawler walking units to increase the distance between the two left and right crawler walking units). Improve construction stability, thereby reducing the width of the fuselage); in some preferred embodiments, the drilling mast mechanism includes a mast, a wellhead working platform on the mast that is detachably arranged on the mast, and a hydraulic tong that is detachably arranged on the mast through a swing arm.
