Description

Technical Field

[0001] This utility model relates to the field of geological drilling rig technology, specifically a portable and detachable lightweight geological drilling rig connection component. Background Technology

[0002] The drilling rig connection assembly is the connecting rod that connects the output end of the drilling rig and the drill bit; it is the drill rod equipment in the traditional sense.

[0003] Existing geological drilling rig connection components use a single drill rod to connect the upper end of the drill rod to the drilling rig's output equipment and the lower end to the drill bit, thereby providing the rotational power of the output equipment to the drill bit for drilling. An excessively long drill rod is not conducive to transportation and carrying, and its fixed length makes it difficult to adjust the connection component, i.e., the drill rod, according to the actual drilling depth requirements. Furthermore, some detachable drill rod connection components often use bolt fasteners for assembly and disassembly, which require tightening each bolt individually, resulting in a cumbersome and inefficient disassembly and assembly process.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a portable and detachable lightweight geological drilling rig connection component. Utility Model Content

[0005] The purpose of this invention is to provide a portable, detachable, lightweight geological drilling rig connection assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable and detachable lightweight geological drilling rig connection assembly, comprising an extension column, a connecting ring fixedly installed at the upper end of the extension column, an insertion hole formed in the center of the surface of the connecting ring, positioning grooves formed on both the left and right sides of the inner surface of the insertion hole, an insertion block fixedly installed at the bottom end of the extension column, grooves formed on both the left and right sides of the surface of the insertion block, springs fixedly installed on the inner surface of each groove, and positioning blocks fixedly installed on the opposite end of each spring.

[0007] Preferably, the positioning block is located on the inner surface of the groove and slides in contact with it, and the opposite end of the positioning block protrudes out of the groove.

[0008] Preferably, the upper and lower sides of the surface of the protruding groove of the positioning block are both set as inclined surfaces, and the overall length of the positioning block is greater than the depth of the positioning groove.

[0009] Preferably, the surface of the extension column is evenly distributed with rotatable ball bearings, and the ball bearings are arranged in four sets in a vertical distribution.

[0010] Preferably, the extension column has a cavity inside, and a reinforcing frame is fixedly installed on the inner surface of the cavity.

[0011] Preferably, the reinforcing frame is spiral in shape and is made of alloy material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the arrangement of a connecting ring, insertion hole, positioning groove, insertion block, recess, spring, and positioning block, allows the insertion block of one extension post to be inserted into the insertion hole of the connecting ring on another extension post. The inner wall of the insertion hole utilizes an inclined surface to push the positioning block, causing it to compress the spring and retract into the recess. When the insertion block is fully inserted into the insertion hole, the positioning block is aligned with the positioning groove. Under the action of the spring, the positioning block is inserted into the positioning groove, thus connecting the two extension posts. The elastic force of the spring, without external interference, only allows the inclined surface of the positioning block to be inserted into the positioning groove, assembling the two extension posts. Because the elastic force only allows the inclined surface of the positioning block to be inserted into the positioning groove, manual force is only needed to pull the two extension posts, and the positioning block can still be connected using the inclined surface. The extension column is pushed and retracted into the groove to complete disassembly. However, when the extension column rotates with the drilling rig, the centrifugal force generated will cause the spring to extend further, allowing the positioning block to be inserted deeper into the positioning groove. At this time, the extension of the positioning block makes its own plane fit with the edge of the positioning groove, which can avoid the positioning block shrinking due to the inclined surface during operation, thus ensuring the stability of the operation. It can be disassembled and assembled very conveniently, and can be flexibly assembled and extended according to the drilling depth requirements. After the entire extension column connects the drill bit and the output end of the drilling rig, it can ensure the stability of the connection during operation, greatly improve the ease of use of the entire connection component, and make disassembly and assembly more efficient.

[0014] 2. This utility model, through the arrangement of ball bearings, cavities, and reinforcing frames, connects the drill bit and the output components of the drilling rig using the extension column as a connector. When drilling downwards, the ball bearings will preferentially contact the surrounding soil. The rolling force of the ball bearings can reduce the friction between the extension column and the soil. When drilling to a deeper layer, the friction between the contact surfaces of multiple assembled extension columns and the soil is very small. This not only makes the entire drilling rig more powerful during drilling but also avoids wear on the extension columns themselves. The cavity can reduce the weight of the entire extension column, making it easier to transport and carry a single extension column. The reinforcing frame can support and strengthen the shape of the entire extension column from the inside, so that the extension column can maintain its shape stability during use even after the inside is hollowed out.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, a portable and detachable lightweight geological drilling rig connection assembly includes an extension column 1, a connecting ring 2 fixedly installed at the upper end of the extension column 1, an insertion hole 3 opened in the middle of the surface of the connecting ring 2, positioning grooves 4 opened on both the left and right sides of the inner surface of the insertion hole 3, an insertion block 5 fixedly installed at the bottom end of the extension column 1, grooves 6 opened on both the left and right sides of the surface of the insertion block 5, springs 7 fixedly installed on the inner surface of each groove 6, and positioning blocks 8 fixedly installed on the opposite end of each spring 7; the positioning blocks 8 slide against the inner surface of the grooves 6, and the opposite end of the positioning blocks 8 protrudes from the grooves 6;

[0021] The upper and lower sides of the surface of the protruding part of the positioning block 8 in the groove 6 are both set as inclined surfaces, and the overall length of the positioning block 8 is greater than the depth of the positioning groove 4.

[0022] By adopting the above technical solution, the insert block 5 of one extension post 1 is inserted into the insertion hole 3 of the connecting ring 2 on another extension post 1. The inner wall of the insertion hole 3 is pushed by the inclined surface to make the positioning block 8 compress the spring 7 and retract into the groove 6. When the insert block 5 is fully inserted into the insertion hole 3, the positioning block 8 is opposite to the positioning groove 4. Under the action of the spring 7, the positioning block 8 is inserted into the positioning groove 4, thus connecting the two extension posts. The elastic force of the spring 7 without external force interference can only make the inclined position of the positioning block 8 insert into the positioning groove 4 to assemble the two extension posts 1. Since the elastic force can only make the inclined position of the positioning block 8 insert into the positioning groove 4, it is only necessary to manually apply force to pull the two extension posts 1, and the positioning block 8 can still use the inclined surface to push and retract into the groove 6, thereby completing the disassembly.

[0023] When the extended column 1 is rotated with the drilling rig, the centrifugal force generated will cause the spring 7 to extend further, so that the positioning block 8 is inserted deeper into the positioning groove 4. At this time, the extension of the positioning block 8 makes its own plane fit with the edge of the positioning groove 4, which can avoid the situation where the inclined surface causes the positioning block 8 to shrink during the operation.

[0024] The drill bit of the drilling rig utilizes the same integral structure of the connecting ring 2, and the output end of the drilling rig utilizes the same integral structure of the insert block 5, and is connected to both ends of the extension column 1 in the same manner as described above.

[0025] Furthermore, the surface of the extension column 1 is evenly distributed with rotating ball bearings 9, and four sets of ball bearings 9 are arranged vertically.

[0026] By adopting the above technical solution, the ball bearing 9 will preferentially contact the surrounding soil. The rolling force of the ball bearing 9 can reduce the friction between the extension column 1 and the soil. When drilling to a deeper layer, the friction between the contact surface of the extension column 1 and the soil is very small. This not only makes the entire drilling machine more powerful when drilling, but also avoids the wear of the extension column 1 itself.

[0027] Furthermore, the extension column 1 has a cavity 10 inside, and a reinforcing frame 11 is fixedly installed on the inner surface of the cavity 10.

[0028] The reinforcing frame 11 is spiral in shape and is made of alloy material.

[0029] By adopting the above technical solution, the cavity 10 can reduce the weight of the entire extension column 1, making it easier to transport and carry a single extension column 1. The reinforcing frame 11 can support and strengthen the shape of the entire extension column 1 inside, so that the extension column 1 can maintain its shape stability during use even after the inside is hollowed out.

[0030] Working Principle: When using this portable, detachable, lightweight geological drilling rig connection assembly, firstly, according to the drilling depth requirements, insert the insert block 5 of one extension column 1 into the insertion hole 3 of the connecting ring 2 on another extension column 1. The inner wall of the insertion hole 3 uses an inclined surface to push and compress the positioning block 8, causing the spring 7 to retract into the groove 6. When the insert block 5 is fully inserted into the insertion hole 3, the positioning block 8 is aligned with the positioning groove 4. Under the action of the spring 7, the positioning block 8 is inserted into the positioning groove 4, thus connecting the two extension columns. The elastic force of the spring 7, without external interference, only allows the inclined surface of the positioning block 8 to be inserted into the positioning groove 4. The two extension columns 1 are then assembled. The drill bit and the output end of the drilling rig also use the same method. The extension cylinder 1 is connected to the upper and lower ends of the drill bit. The drill output end can then drive the entire extension cylinder 1 to rotate the drill bit for drilling. When the extension cylinder 1 rotates with the drill, the centrifugal force generated causes the spring 7 to extend further, allowing the positioning block 8 to insert more deeply into the positioning groove 4. At this time, the extension of the positioning block 8 ensures its plane fits against the edge of the positioning groove 4, preventing the positioning block 8 from shrinking due to the inclined surface during operation, thus ensuring stable operation. As the drill output end moves downwards, pushing the drill bit downwards, when the output end is close to the ground and can no longer move downwards, the output end can be stopped. At this point, the entire equipment stops rotating, and the centrifugal force is lost. The elastic force can only insert the inclined surface of the positioning block 8 into the positioning groove 4. Therefore, only manual force is needed to pull the two extension columns 1. The positioning block 8 can still be pushed and retracted into the groove 6 by the inclined surface, thus completing the disassembly. The drill output end and the uppermost extension column 1 are also disassembled in the same way. At this time, the extension column 1 can continue to be assembled and extended above the ground, so that the drill output end can continue to push the drill bit to drill deeper from top to bottom. There is no need to manually assemble the entire length of the extension column 1 first. The entire drilling equipment can be assembled in working periods. When drilling downwards, the ball bearing 9 will first contact the surrounding soil. The rolling force of the ball bearing 9 can reduce the friction between the extension column 1 and the soil. When drilling to deeper layers, the friction between the contact surfaces of numerous assembled extension columns 1 and the soil is minimal. This not only enhances the drilling power of the entire rig but also prevents wear on the extension columns 1 themselves. Once the entire equipment is in use, the extension columns 1 and the rig structural components can be disassembled using the same disassembly steps described above. The disassembled extension columns 1 are all independent small columns, rather than a single column. The cavity 10 reduces the weight of the entire extension column 1, making it easy to carry and store. The reinforcing frame 11 internally supports and strengthens the shape of the entire extension column 1, ensuring that the extension column 1 remains stable during use even after being hollowed out. This is the working principle of this portable, detachable, lightweight geological drilling rig connection assembly.
