Description

TECHNICAL FIELD

[0001] The utility model relates to drilling equipment technical field especially is related to a drill rod loading and unloading auxiliary device. BACKGROUND

[0002] In many drilling operations, especially in small geological exploration projects or shallow hole drilling operations, the loading and unloading process of drill rods usually relies on manual operation. These operation sites usually face special working conditions such as narrow space and complex terrain, and traditional automated equipment such as power catwalk and similar automated devices usually cannot adapt to these specific environments due to the large size of the equipment, complex installation or the need for a large operating space. Although automated equipment is widely used in other scenarios, under these restricted conditions, the existing technology cannot be effectively implemented, and manual operation is still the only viable option.

[0003] In this case, manual operation is involved in many key links throughout the entire tripping process, including the handling, placement and stabilization of drill rods. Although manual operation is inevitable in these links, it has many problems, such as the drill rod is usually long and heavy, the worker needs to frequently lift, place and handle the drill rod, which is labor-intensive. Especially when the drilling depth is large, the weight of the drill rod makes the operation more laborious, which can easily cause the worker to be tired and affect work efficiency; or because the drill rod is heavy and bulky, there is a high safety risk when manually operating it. The drill rod may slip, tilt, or cause hand pinching, foot bruising, etc., especially when the drill rod needs to be frequently operated during drilling, the safety risk of the worker increases; at the same time, manual operation not only needs to rely on the worker's physical strength, but also is limited by physical strength, resulting in low efficiency. In operations that require frequent lifting and placement of drill rods, the worker needs to rest and recover several times, which delays the operation time and affects the construction progress; and in manual operation, there is usually no effective support and stabilization system, and the drill rod often tilts or loses stability during lifting or placement, especially when the drill rod is moved to the front of the drilling machine, the drill rod is prone to tilt or slide, causing unstable operation, and even may cause drill rod damage or repeated work.

[0004] Although manual operation is inevitable under these special working conditions, the high labor intensity, safety hazards and low efficiency caused by manual operation need to be solved. Therefore, a new type of drill rod loading and unloading auxiliary device is needed, which can efficiently and safely load and unload drill rods in limited space and complex terrain, reduce unnecessary risks and labor intensity caused by manual operation, improve operation efficiency, and ensure the stability and safety of the drill rod loading and unloading process. SUMMARY

[0005] To solve the above technical problems, the utility model provides a drill rod loading and unloading auxiliary device based on a track, which adopts the following technical solutions:

[0006] The application discloses a drilling rod loading and unloading auxiliary device, which comprises a drilling machine, a track and a scooter.

[0007] The track is arranged in front of the drilling machine and horizontally arranged on the ground, one end of the track is close to the drilling hole, and the other end extends to the front of the drilling machine, and the length of the track is not less than the sum of the lengths of three drilling rods.

[0008] Further, the track is composed of two channel steels, the notches of the two channel steels are vertically upward, and the two channel steels are reinforced by welding thin steel plates.

[0009] The two rows of pulleys of the rectangular scooter are respectively embedded in the corresponding notches, the force is symmetrical, the guidance is accurate, and the scooter can stably travel on the assembled track with low resistance, so that the safety, stability and efficiency of the drilling rod transfer are further improved, and the quick disassembly, assembly and relocation of the scooter in the field working condition are facilitated.

[0010] Further, the scooter is filled with buffer blocks for supporting the end of the drilling rod and buffering and protecting the end of the drilling rod during the sliding process.

[0011] The buffer blocks arranged on the scooter form an elastic layer between the end of the drilling rod and the body of the scooter, which can absorb the impact generated by lifting and lowering the drilling rod, prevent the drilling rod from being damaged due to bumping, prevent the end of the drilling rod from moving forward or swinging sideways due to inertia during the sliding process of the scooter, and keep the posture of the drilling rod stable, thereby preventing the end of the drilling rod from being worn.

[0012] Further, the scooter is filled with multiple sections of buffer blocks, which are used to pad the drill pipe end and play a buffering and protecting role to prevent the drill pipe from rubbing or colliding with other components during sliding; the filling height of the buffer blocks away from the drilling rig direction on the scooter is slightly higher than that of the buffer blocks close to the drilling rig direction, so as to help stabilize the drill pipe and prevent tilting, and the height difference of the buffer blocks is used to prevent the drill pipe from sliding forward during sliding.

[0013] By adopting the technical scheme, the top of the scooter is arranged with multiple sections of buffer blocks, and the filling height of the buffer blocks away from the drilling rig direction is slightly higher, so that the drill pipe end can be effectively held during sliding, thereby avoiding tilting or collision.

[0014] Further, the buffer blocks can be made of any one of wood, rubber and plastic.

[0015] By adopting the technical scheme, the buffer block material can be selected from wood, rubber and plastic according to the site conditions, so as to meet the requirements of wear resistance, vibration reduction and easy replacement, thereby further improving the safety of the loading and unloading process and the protection effect of the drill pipe.

[0016] Further, a plurality of sleepers are arranged on the ground on the same side of the track, the sleepers are all perpendicular to the track and are uniformly arranged along the extension direction of the track, and the same end of the sleepers is in contact with one side of the track, so as to roll the disassembled drill pipe onto the sleepers.

[0017] By adopting the technical scheme, when the disassembled drill pipe is rolled out from the side of the scooter, it can be directly placed on the sleepers without the need for workers to hold or seek additional fulcrums for a long time.

[0018] The beneficial effects of the utility model lie in:

[0019] 1. By means of the cooperation of the scooter and the main hoist of the drilling rig, the stand can be stably moved to the front of the drilling rig at one time without manual shoulder carrying or segmented carrying, and the auxiliary time for tripping in and out is greatly shortened.

[0020] 2. When the scooter rolls on the track, the notch vertically upward can effectively prevent lateral derailment, the buffer block absorbs and disperses the impact when the drill pipe is lifted and placed, avoids the hard collision between metals to cause the damage of the thread or the inclination of the drill pipe; through the segmented height design, the drill pipe can also avoid the unexpected such as front jump and side swing, and the stability of the whole carrying process is enhanced. The disassembled drill pipe can be directly rolled to the sleeper, preventing disordered rolling or dumping, and further improving the safety of the on-site operation.

[0021] 3. The buffer block arranged on the scooter can effectively reduce the direct collision and friction between the drill pipe and the surface of the scooter, reduce the probability of accidental wear of the drill pipe during loading and unloading, and make the whole construction more economical and reliable.

It should be noted that, in the case of no conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0029] Embodiment 1:

[0030] Reference Figure 1 , Figure 2The embodiment provides a drill rod loading and unloading auxiliary device, which comprises a drilling machine 1, a track 2 and a scooter 3, the track 2 is arranged in front of the drilling machine 1 and horizontally laid on the ground, one end of the track 2 is close to a drilling hole 101, the other end extends to the front of the drilling machine 1, and the length of the track 2 is not less than the sum of the lengths of three drill rods; the scooter 3 is arranged on the track 2, a pulley 301 is arranged below the scooter 3, the width of the pulley 301 of the scooter 3 is the same as the width of the track, the scooter can slide along the track by manual pushing or mechanical driving, and the scooter is used for carrying and guiding the drill rod to slide.

[0031] The drilling machine 1 is arranged on the ground and used for performing geological drilling operation, wherein the drilling machine is provided with the drilling hole 101 for inserting the drill rod into the stratum, the drill rod is vertically arranged in the drilling hole, is driven to rotate and drill by a power head slip 104, and is lifted and lowered by a main winch 103 of the drilling machine.

[0032] The track 2 is horizontally arranged on the ground in front of the drilling machine 1, is composed of channel steels 201 on two sides, the notches of the channel steels 201 on the two sides are vertically upward, and the length of the track 2 is not less than the length of one stand 102 (namely the sum of the lengths of three drill rods). The channel steels 201 between the two sides are connected and reinforced by welding a plurality of thin steel plates 202, so as to form a stable double slide structure, and the track 2 is used for supporting the sliding operation of the scooter 3.

[0033] The scooter 3 is arranged on the track 2 and adopts a rectangular frame structure, rolling pulleys 301 are arranged below the two sides of the scooter 3 respectively, the pulleys 301 are embedded in the notches of the channel steels 201 on the two sides of the track 2 and can slide in the direction of the track 2 with low resistance. A plurality of buffer blocks 302 are arranged above the scooter 3.

[0034] The buffer block 302 can be made of any one of wood, rubber and plastic according to the field conditions, and can meet the requirements of wear resistance, vibration reduction and easy replacement, and the main role is to form an elastic layer between the drill rod end and the scooter body, so as to absorb the impact generated by lifting and lowering the drill rod, prevent the drill rod from being damaged due to knocking, prevent the drill rod end from moving forward or swinging sideways due to inertia in the sliding process of the scooter, so as to keep the posture of the drill rod stable and prevent the drill rod end from being worn.

[0035] The working principle of the embodiment is as follows:

[0036] During drill rod loading and unloading operations, when it is necessary to lift the drill rod, the operator pushes the trolley 3 to a position near the borehole opening 101; the main winch 103 of the drilling rig lifts one stand 102 (consisting of three drill rods), the power head slip 104 temporarily clamps the drill rod in the hole, and then unscrews the threads, allowing the operator to place the lower end of the stand 102 on the trolley 3. Subsequently, while the trolley 3 slides forward along the track manually or mechanically, the main winch 103 slowly and synchronously lowers the other end of the stand 102, gradually leveling the drill rod. After sliding to the designated position, the drill rod can be smoothly loaded and unloaded. The reverse process is followed for lowering the drill rod.

[0037] Example 2:

[0038] Reference Figure 3 In this embodiment, based on embodiment 1, multiple buffer blocks 302 are provided above the scooter 3 to cushion the drill rod end and provide buffering and protection, preventing the drill rod end from rubbing or colliding with other rigid components during sliding and damaging the drill bit. The filling height of the buffer blocks 302 on the scooter 3 away from the drilling rig is slightly higher than that of the buffer blocks 302 closer to the drilling rig. This height difference of the buffer blocks 302 is used to prevent the drill rod from sliding forward during sliding, thus helping to stabilize the drill rod and prevent the drill rod from tilting excessively when the scooter 3 slides forward. Figure 3 In the middle, the right side of the scooter 3 is the side closest to the drill. The support 102 is placed at an angle in the middle of the buffer block 302 as shown in the figure. As the scooter 3 slides forward, the support 102 may slide forward due to the reduced friction when it is tilted, and will be blocked by the part with a higher filling height on the side further away from the drill.

[0039] The working principle of this embodiment:

[0040] The top of the scooter 2 features a multi-segmented buffer block arrangement, with a slightly higher filling height for the buffer block 302 furthest from the drill rig 1. This effectively supports the drill rod end during sliding, preventing it from tilting forward or colliding. This height difference design prevents the drill rod end from easily lurching forward under sliding inertia, maintaining a better overall horizontal posture. Simultaneously, the multi-segment buffer block 302 facilitates segmented replacement and material selection, providing zoned buffering and protection for the drill rod while reducing wear and increasing durability, further enhancing the safety and stability of the drill rod loading and unloading process.

[0041] Example 3:

[0042] Reference Figure 4 , Figure 5On the basis of embodiment 1, a plurality of sleepers 4 are arranged on the ground on the same side of the track 2, and the plurality of sleepers 4 are arranged in a uniform manner perpendicular to the track 2 and along the extension direction of the track 2, and the same end of the plurality of sleepers 4 is in contact with one side of the track 2, for rolling the disassembled drill pipe onto the sleepers 4.

[0043] The working principle of the present embodiment is as follows:

[0044] When the disassembled drill pipe is rolled out from the side of the scooter 3, it can be directly placed on the sleepers 4 without the need for workers to hold or seek additional fulcrums for a long time. Through this configuration, on the one hand, the risk of disordered rolling or dumping of the drill pipe after leaving the scooter 3 is effectively prevented, and on the other hand, the wear and tear or damage caused by the contact between the drill pipe and the ground is reduced, thereby improving the safety and convenience of the loading and unloading operation.
