Description

Technical Field

[0001] The present application relates to the technical field of drilling rigs, and in particular to a vehicle-mounted drilling rig. Background Art

[0002] A drilling rig is a complex machine consisting of a machine, a unit and a mechanism. It is a mechanical device that drives the drill to drill underground to obtain physical geological data during exploration or mineral resource development. It is also called a drilling machine. Its main function is to drive the drill to break the rock at the bottom of the hole. The drill that is lowered or pulled out of the hole can be used to drill cores, ore cores, rock cuttings, gas samples, liquid samples, etc. to explore the underground geology and mineral resources.

[0003] The existing patent (publication number: CN215408453U) discloses a petroleum vehicle-mounted drilling rig with a protective structure, which specifically relates to the technical field of drilling rigs, including a bottom plate, a drilling mechanism and a protective mechanism. An adjustment mechanism is provided on the top of the bottom plate, and the adjustment mechanism includes two pressure cylinders, a push rod is provided inside the pressure cylinder, and a top plate is provided on the top of the bottom plate. The utility model sets an adjustment mechanism, uses an air intake pipe and an air pump to introduce external air into the pressure cylinder, and the pressure of the air pushes the push rod to move downward and then pushes the drill bit to move downward to drill holes. When the drill bit encounters rocks and the drilling speed slows down, the pressure inside the pressure cylinder will gradually increase and push the piston downward, so that the plug rod at the bottom of the piston is inserted into the jack, until the two electrode columns contact each other, the air pump will stop working, while maintaining the thrust during drilling, avoiding excessive thrust and slow speed of the drill bit moving downward to cause damage to the drill bit.

[0004] The above-mentioned document often uses low-speed drilling during the drilling process using a drill bit, so that the drill bit can drill materials with higher toughness. However, in the above-mentioned document, when the pressure of the drill bit is too high, the power output will be shut down, causing the drill bit to lose power during low-speed operation and unable to adjust the pressure limit. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a vehicle-mounted drilling rig having advantages such as improved drill bit protection capability, and solves the problems raised in the background technology.

[0007] Through the above scheme, installing a pressure sensor can detect the air pressure in the pressure cylinder, which is convenient for monitoring the pressure changes in the pressure cylinder.

[0008] Furthermore, a sealing ring is fixedly connected to the outer surface of the sliding member, and the sealing ring is in contact with the inner wall of the pressure cylinder.

[0009] Through the above scheme, the installation of the sealing ring can seal the inside of the pressure cylinder, so that the pressure in the pressure cylinder can be kept balanced.

[0010] Furthermore, a drill bit is installed on the bottom surface of the sliding member, and a buffer pad is fixedly connected to the outer surface of the sliding member and the bottom surface of the pressure cylinder.

[0011] Through the above solution, installing the buffer pad can improve the protection of the pressure cylinder and avoid damage to the pressure cylinder caused by friction between the drill bit and the pressure cylinder.

[0012] Furthermore, the outer surface of the pressure cylinder is provided with two groups of limit grooves distributed at equal distances, and the inner wall of the support frame is provided with two sliding grooves, and both sliding grooves are slidably connected with a clamping block, and both the clamping blocks are clamped with the limit grooves adjacent to them.

[0013] Through the above solution, the cooperation between the mounting block and the limiting groove can position the pressure cylinder, thereby preventing the pressure from being transmitted to the threaded rod and affecting the use of the threaded rod when drilling with a drill bit.

[0014] Furthermore, the side surfaces of the two clamping blocks that are away from each other are fixedly connected with elastic members, and the other ends of the two elastic members are fixedly connected with the sliding grooves that are close to them.

[0015] Through the above solution, the elastic member is installed so that the clamping block is always located in the limiting groove through the deformation force of the elastic member, so that the pressure cylinder can be stably located in the support frame.

[0016] Furthermore, ends of the two clamping blocks that are away from each other are fixedly connected with pull rods, and the two pull rods completely penetrate the support frame and are slidably plugged with the support frame.

[0017] Through the above scheme, the installation pull rod can separate the block from the limiting groove when the pull rod is pulled, so as to release the limiting of the pressure cylinder and facilitate the adjustment of the pressure cylinder.

[0018] Furthermore, a support frame is fixedly connected to the outer surface of the support frame, and a plurality of mounting holes are formed on the upper surface of the support frame.

[0019] Through the above solution, the cooperation between the mounting support frame and the mounting hole can facilitate the connection to the external power device and enable the power to be transmitted to the support frame.

[0020] Furthermore, the upper ends of the two clamping blocks are both chamfered, and the two elastic members are both in a reset state.

[0021] Through the above solution, the clamping block can drive the pressure cylinder to rotate during the rotation of the support cylinder, so that the pressure cylinder can rotate the sliding part, so that the drill bit can drill the ground.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The vehicle-mounted drilling rig can adjust the distance between the sliding part and the proximity sensor by installing a threaded rod, and can adjust the air pressure in the pressure cylinder by cooperating with an electric valve, thereby increasing the limit of pressure required when interrupting power output, making it easier for the drill bit to perform low-speed drilling work.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

By installing the threaded rod 5, the distance between the sliding member 3 and the proximity sensor 4 can be adjusted, and the air pressure in the pressure cylinder 2 can be adjusted by cooperating with the electric valve, so that the limit of the pressure required when the power output is interrupted can be increased, which is convenient for the drill bit 10 to perform low-speed drilling work.

[0032] See also Figure 1 , Figure 2 and Figure 3 A sealing ring 9 is fixedly connected to the outer surface of the sliding member 3, and the sealing ring 9 contacts the inner wall of the pressure cylinder 2. The installation of the sealing ring 9 can seal the pressure cylinder 2 so that the pressure in the pressure cylinder 2 can be kept balanced. A drill bit 10 is installed on the bottom surface of the sliding member 3. A buffer pad 11 is fixedly connected to the outer surface of the sliding member 3 and the bottom surface of the pressure cylinder 2. The installation of the buffer pad 11 can improve the protection of the pressure cylinder 2 and avoid damage to the pressure cylinder 2 caused by friction between the drill bit 10 and the pressure cylinder 2. A support frame 17 is fixedly connected to the outer surface of the support frame 1. A plurality of mounting holes 18 are provided on the upper surface of the support frame 17. The cooperation between the installation of the support frame 17 and the mounting holes 18 can facilitate the connection to the external power device and enable the power to be transmitted to the support frame 1.

[0033] See also Figure 1 , Figure 2 and Figure 3The outer surface of the pressure cylinder 2 is provided with two groups of limit grooves 12 distributed at equal distances, and the inner wall of the support frame 1 is provided with two sliding grooves 13, and the two sliding grooves 13 are slidably connected with a card block 14, and the two card blocks 14 are clamped with the limit grooves 12 close to them. The cooperation of the installation card block 14 and the limit groove 12 can position the pressure cylinder 2 to avoid the pressure being transmitted to the threaded rod 5 and affecting the use of the threaded rod 5 when the drill bit 10 is used for drilling. The side surfaces of the two card blocks 14 that are away from each other are fixedly connected with elastic members 15, and the other ends of the two elastic members 15 are fixedly connected with the sliding grooves 13 close to them. The installation of the elastic member 15 can make the card block 1 deform through the deformation force of the elastic member 15. 4 is always located in the limiting groove 12, so that the pressure cylinder 2 can be stably located in the support frame 1, and the ends of the two clamping blocks 14 that are away from each other are fixedly connected with the pull rod 16, and the two pull rods 16 completely penetrate the support frame 1 and are slidably plugged with the support frame 1. When the pull rod 16 is installed, the clamping block 14 can be separated from the limiting groove 12 when the pull rod 16 is pulled, and the limit on the pressure cylinder 2 can be released, which is convenient for adjusting the pressure cylinder 2. The upper ends of the two clamping blocks 14 are chamfered, and the two elastic members 15 are in the reset state. The clamping block 14 can drive the pressure cylinder 2 to rotate during the rotation of the support cylinder, so that the pressure cylinder 2 can rotate the sliding member 3, so that the drill bit 10 can drill the ground.

[0034] A vehicle-mounted drilling rig in this embodiment can adjust the distance between the sliding member 3 and the proximity sensor 4 by installing a threaded rod 5, and can adjust the air pressure in the pressure cylinder 2 by cooperating with an electric valve, thereby increasing the limit of the pressure required when the power output is interrupted, making it easier for the drill bit 10 to perform low-speed drilling work.

[0035] The working principle of the above embodiment is as follows: when the drill bit 10 is used for low-speed drilling, the threaded rod 5 is rotated so that the thread drives the pressure cylinder 2 to rise in the support frame 1. At this time, the electric valve 7 is opened to allow the outside air to enter the pressure cylinder 2. At this time, the distance between the sliding member 3 and the proximity sensor 4 is adjusted. The pressure required when the two are in contact will be greater, thereby achieving the purpose of adjusting the limit of the required pressure. When the external power source starts the support frame 17 to rotate, the support frame 17 can drive the support frame 1 to rotate, so that the support frame 1 drives the pressure cylinder 2 to rotate through the two blocks 14. When the pressure cylinder 2 rotates, it can drive the drill bit 10 to rotate through the sliding member 3 to perform low-speed drilling on the ground. When the pressure increases to the point where the sliding member 3 contacts the proximity sensor 4, the power output will be interrupted to avoid damage to the drill bit 10. The pressure sensor 6 is installed to detect the air pressure in the pressure cylinder 2, which is convenient for monitoring the pressure changes in the pressure cylinder 2.
