Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a wear-resistant drilling rod for mining geological exploration. Background Technology

[0002] Mining geological exploration drill pipe is one of the key pieces of equipment used in mining, geological exploration and underground resource detection. It is mainly used in mining geological exploration. It penetrates underground rock strata and collects geological samples by rotating and striking. It is usually composed of multiple connecting sections, and each section is connected by a connecting joint to facilitate extending the drilling depth.

[0003] Most existing mine geological exploration drill pipes use threaded connections to fix the drill bit, making the installation and removal of the drill bit cumbersome and time-consuming. This not only increases the operation time and affects the exploration efficiency, but also, since most mine geological exploration drill pipes are made of metal materials, although they have a certain strength, the surface of the drill pipe is easily affected by wear, corrosion and moisture penetration during long-term use, leading to a decline in its performance and a reduction in the service life of the equipment.

[0004] Therefore, those skilled in the art have provided a wear-resistant drilling rod for mining geological exploration to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wear-resistant drilling rod for mining and geological exploration. This device utilizes a coating mechanism: a diamond coating enhances the surface hardness and wear resistance of the main drill rod, effectively preventing wear caused by friction; a polytetrafluoroethylene (PTFE) waterproof coating improves the water resistance of the main drill rod, effectively preventing moisture intrusion; and an epoxy resin coating enhances its corrosion resistance, thereby extending the device's service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wear-resistant drilling rod for mining geological exploration includes a main drill rod. An installation mechanism is provided at the lower end of the main drill rod. The installation mechanism includes a first wedge block fixedly connected to the lower surface of the main drill rod. The first wedge block has a cavity inside. A groove is formed on the inner wall of the front end of the cavity. A rotating rod is disposed inside the groove. A threaded rod is fixedly connected to the outer wall of the rear end of the rotating rod. Multiple moving blocks are sleeved on the body of the threaded rod. Fixed blocks are slidably connected to both sides of the bottom surface of the cavity. Multiple hinged rods are hinged to the inner walls of the two fixed blocks on their adjacent sides. Two second wedge blocks are provided at the lower end of the first wedge block.

[0008] The outer wall of the main drill pipe is provided with a coating mechanism, which includes a corrosion-resistant coating, a waterproof coating, and a wear-resistant coating.

[0009] Through the above technical solution, the device can quickly install and remove drill bits on the main drill rod through the installation mechanism, thereby improving the efficiency of drill bit maintenance and replacement. Furthermore, through the use of the coating mechanism, the hardness, wear resistance, water resistance, and corrosion resistance of the main drill rod can be improved, thus extending the service life of the device.

[0010] Furthermore, the first wedge block and the second wedge block are engaged, and the front ends of the two second wedge blocks, which are close to each other on one side of the outer wall, are provided with fixing grooves.

[0011] The above technical solution allows the main drill pipe and drill bit to be connected via the first wedge block and the second wedge block.

[0012] Furthermore, the fixed block is engaged with the fixed groove, the hinge rod is hinged to the moving block, and the threaded rod is threaded to the moving block.

[0013] The above technical solution enables the movable block to move by driving the fixed block through the hinge rod.

[0014] Furthermore, a nut is fixedly connected to the outer wall of the front end of the rotating rod, and the outer wall of the rear end of the threaded rod is rotatably connected to the cavity.

[0015] The above technical solution allows the rotating rod to be rotated more easily by using a nut.

[0016] Furthermore, the corrosion-resistant coating is disposed on the outer wall of the main drill pipe, the waterproof coating is disposed on the outer wall of the corrosion-resistant coating, and the wear-resistant coating is disposed on the outer wall of the waterproof coating.

[0017] The above technical solutions enable the use of corrosion-resistant coatings, waterproof coatings, and wear-resistant coatings in combination, thereby improving the service life of the device.

[0018] Furthermore, the corrosion-resistant coating is made of epoxy resin, the waterproof coating is made of polytetrafluoroethylene, and the wear-resistant coating is made of diamond.

[0019] The above technical solutions can improve the wear resistance, water resistance, and corrosion resistance of the device through epoxy resin coating, polytetrafluoroethylene coating, and diamond coating.

[0020] Furthermore, a drill bit is provided at the lower end of the second wedge block, and the upper surface of the drill bit is fixedly connected to the lower surface of the two second wedge blocks.

[0021] The above technical solution enables the use of drill bits to explore the geological conditions of mines.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a wear-resistant drilling rod for mining geological exploration. The device, through an installation mechanism, connects the main drill rod and the drill bit via a first wedge block and a second wedge block. By inserting a tool into the nut and rotating it, the fixing block can be indirectly moved into the fixing groove, thereby fixing the first wedge block and the second wedge block together. This allows the drill bit to be quickly installed and removed from the main drill rod, thus improving the efficiency of drill bit maintenance and replacement.

[0024] 2. This utility model proposes a wear-resistant drilling rod for mining geological exploration. The device uses a coating mechanism. The wear-resistant coating material is diamond coating, which can improve the surface hardness and wear resistance of the main drill rod and effectively prevent wear caused by friction. The waterproof coating material is polytetrafluoroethylene coating, which can improve the waterproofness of the main drill rod and effectively prevent water from penetrating the main drill rod. The corrosion-resistant coating material is epoxy resin coating, which can improve the corrosion resistance of the main drill rod, thereby increasing the service life of the device.

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.

[0037] Reference Figure 1 , Figure 5 and Figure 6 One embodiment provided by this utility model:

[0038] A wear-resistant drilling rod for mining geological exploration includes a main drill rod 1. An installation mechanism 2 is provided at the lower end of the main drill rod 1. The installation mechanism 2 includes a first wedge block 201 fixedly connected to the lower surface of the main drill rod 1. A cavity 203 is opened inside the first wedge block 201. A groove 204 is opened on the inner wall of the front end of the cavity 203. A rotating rod 205 is arranged inside the groove 204. A threaded rod 207 is fixedly connected to the outer wall of the rear end of the rotating rod 205. Multiple moving blocks 208 are sleeved on the rod body of the threaded rod 207. Fixed blocks 2010 are slidably connected to both sides of the bottom surface of the cavity 203. Multiple hinge rods 209 are hingedly connected to the inner wall of the side of the two fixed blocks 2010 that are close to each other. Two second wedge blocks 202 are provided at the lower end of the first wedge block 201.

[0039] The outer wall of the main drill pipe 1 is provided with a coating mechanism 3, which includes a corrosion-resistant coating 301, a waterproof coating 302, and a wear-resistant coating 303.

[0040] The device allows the drill bit 4 to be quickly installed and removed from the main drill rod 1 via the installation mechanism 2, thereby improving the efficiency of maintenance and replacement of the drill bit 4. Furthermore, with the cooperation of the coating mechanism 3, the hardness, wear resistance, water resistance, and corrosion resistance of the main drill rod 1 can be improved, thus extending the service life of the device.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The first wedge block 201 and the second wedge block 202 are engaged and fitted together. The front ends of the two second wedge blocks 202, which are close to each other on one side of the outer wall, are provided with fixing grooves 2011, so that the main drill rod 1 and the drill bit 4 can be connected through the first wedge block 201 and the second wedge block 202.

[0042] Reference Figure 1 , Figure 2 and Figure 5 The fixed block 2010 is engaged with the fixed groove 2011, the hinge rod 209 is hinged to the movable block 208, and the threaded rod 207 is threaded to the movable block 208, so that the movable block 208 can drive the fixed block 2010 to move through the hinge rod 209.

[0043] Reference Figure 1 , Figure 3 and Figure 5 The outer wall of the front end of the rotating rod 205 is fixedly connected to a nut 206, and the outer wall of the rear end of the threaded rod 207 is rotatably connected to the cavity 203, so that the rotating rod 205 can be rotated more easily through the nut 206.

[0044] Reference Figure 2 and Figure 6 A corrosion-resistant coating 301 is applied to the outer wall of the main drill pipe 1, a waterproof coating 302 is applied to the outer wall of the corrosion-resistant coating 301, and a wear-resistant coating 303 is applied to the outer wall of the waterproof coating 302. This allows the corrosion-resistant coating 301, the waterproof coating 302, and the wear-resistant coating 303 to be used together, thereby improving the service life of the device.

[0045] Reference Figure 2 and Figure 6 The corrosion-resistant coating 301 is made of epoxy resin, the waterproof coating 302 is made of polytetrafluoroethylene, and the wear-resistant coating 303 is made of diamond. Thus, the wear resistance, waterproofness, and corrosion resistance of the device can be improved by using epoxy resin coating, polytetrafluoroethylene coating, and diamond coating.

[0046] Reference Figure 1 and Figure 4 The lower end of the second wedge 202 is provided with a drill bit 4. The upper surface of the drill bit 4 is fixedly connected to the lower surface of the two second wedges 202, so that the geological exploration of the mine can be carried out through the drill bit 4.

[0047] Working principle: During use, the first wedge block 201 below the main drill rod 1 and the second wedge block 202 above the drill bit 4 are engaged. When a wrench is inserted into the nut 206, rotating the wrench causes the rotating rod 205 and the threaded rod 207 to rotate. At this time, the moving block 208 moves backward through the threaded connection, which in turn moves the hinge rod 209. This allows the fixed block 2010 to move to both sides of the cavity 203, so that the fixed block 2010 enters the fixing groove 2011, thereby allowing the drill bit to move. 4. It can be quickly connected to the main drill pipe 1, and can still be quickly disassembled and replaced in reverse operation. The wear-resistant coating 303 can improve the surface hardness and wear resistance of the main drill pipe 1, and can effectively prevent wear caused by friction. The waterproof coating 302 can improve the waterproofness of the main drill pipe 1, and can effectively prevent water from entering the main drill pipe 1. The corrosion-resistant coating 301 can improve the corrosion resistance of the main drill pipe 1, and can effectively resist the erosion of corrosive media such as acids, alkalis and salts, thereby improving the service life of the device.
