Description

Technical Field

[0001] The utility model relates to the technical field of coal mine drills, in particular to a small-volume automatic drill truck with a sinking drill pipe frame. Background Art

[0002] The process of industrialized coal production in China has now entered an era of safe and efficient mining. A coal mine is a reasonable space excavated by humans when digging a geological layer rich in coal, usually including roadways, shafts, and working faces, etc. When drilling a coal mine, a drill truck device will be used. The drill pipe and drill bit on the drill truck device rotate through power output and drill the coal mine. With the increasing demand for coal mine drilling and the increasing length of continuous drilling required, more and more drill pipes need to be assembled accordingly. Assembling a large number of drill pipes not only makes the load of the drill heavier, but also makes the drill pipe frame of the drill larger, resulting in a large, bulky, and lengthy drill rig body, which is not conducive to the flexible application of the drill truck in narrow mine roadways.

[0003] The automation and unmanned level of the drills in the original small and medium-sized coal mines are not high. At present, the market demand for automatic drill trucks is very large. However, due to the limited space in the roadways of small and medium-sized coal mines, the requirements for automatic drill trucks are not only high in automation and unmanned level, reducing the personnel configuration and the labor intensity of workers, but also compact in structure and small in size in terms of external dimensions, capable of being conveniently transported to the operation area, and capable of freely completing operations in the limited roadway space. Therefore, the small-volume compactification of automatic drill trucks is the research direction of the current industry. Summary of the Utility Model

Embodiment 1

[0032] See Figures 1 - 8 , Figure 1The structural schematic diagram of a small-volume automatic drill rig with a sinking drill pipe frame is drawn.

A working platform 2 is arranged above the main machine frame 1. On the working platform 2, there are successively arranged a main machine operation console 9, a drill pipe frame assembly 3, a manipulator 4, and a support column 5. The main machine crawler assembly 10 is fixed on both sides of the main machine body 1 and contacts the ground for moving the main machine body 1.

[0033] The main machine body 1 includes a left body and a right body arranged symmetrically left and right. The left body includes a left support cross plate 1.1 and a left support vertical plate 1.2. The left support cross plate 1.1 and the left support vertical plate 1.2 are perpendicularly connected. The left support cross plate 1.1 is a rectangular plate with a square notch at one corner. The left support vertical plate 1.2 is a rectangular plate. The side of the left support cross plate 1.1 with the notch is perpendicularly connected to the side of the left support vertical plate 1.2. The right body includes a right support cross plate 1.3 and a right support vertical plate 1.4. The structure of the right body is the same as that of the left body and is symmetrically arranged.

[0034] A connecting plate 1.5 is arranged between the front ends of the left support vertical plate 1.2 and the right support vertical plate 1.4 for connection. Thus, a drill pipe frame sinking area is formed between the left body and the right body.

[0036] The working platform 2 is a rectangular plate. There is a sinking opening 2.1 at the rear end of the working platform 2. The sinking opening 2.1 is a square notch.

[0037] The drill pipe frame assembly 3 includes an upper frame 3.1. A stretching frame 3.2 is arranged below the upper frame 3.1. Multiple partition plates are arranged in the upper frame 3.1 for storing drill pipes in an orderly manner. On the front and rear two sides of the upper frame 3.1, there are respectively arranged a pair of upper frame lifting oil cylinders. The output shafts of the upper frame lifting oil cylinders are connected to the stretching frame 3.2 through ear seats. On the left and right sides of the stretching frame 3.2, there are symmetrically arranged two support seats 3.3 with the same structure. A row of through holes are arranged on the support seats 3.3, and drill pipe carrying rods are detachably arranged in the through holes. The drill pipe carrying rods are used to support the upper frame 3.1 by the support seats 3.3. A row of chutes are arranged on the side of the stretching frame 3.2 corresponding to the positions of the drill pipe carrying rods for the drill pipe carrying rods to be inserted into the stretching frame 3.2 and move up and down along the chutes.

Below the lifting platforms 3.6, there are lifting cylinders. The sliding seats of the lifting cylinders are connected to the second propulsion cylinders. The lifting cylinders lift the lifting platforms 3.6, and the second propulsion cylinders move the lifting platforms 3.6 back and forth.

[0039] The inner frame 3.4 includes an inner frame body, which is a rectangular box with an open top surface. The width of its lower part is smaller than that of its upper part, and its cross-section is T-shaped. The width of the lower part of the inner frame body matches the width of the sunken area of the drill pipe frame of the main body machine 1, and the width of the upper part of the inner frame body matches the width of the sunken opening 2.1 of the working platform 2. Thus, the lower part of the inner frame 3.4 passes through the sunken opening 2.1 and sinks into the sunken area of the drill pipe frame. The bottom surfaces on both sides of the upper part of the inner frame 3.4 are set on the main body machine 1. The stretching frame 3.2 is arranged on both sides of the sunken opening 2.1 of the working platform 2.

[0040] There is a drill pipe pushing mechanism 3.7 between the lower frame assembly and the robotic arm 4. The drill pipe pushing mechanism 3.7 includes a slide rail seat. On the slide rail seat, there is an oil cylinder mounting seat. The drill pipe pushing oil cylinder is connected to the oil cylinder mounting seat. The drill pipe pushing oil cylinder is connected to the second guide rod. There are two rod placing frames on the second guide rod. The structure of the rod placing frames is the same as that of the drill pipe platforms 3.5, and it is used to transport the drill pipes to the corresponding positions of the robotic arm 4.

[0041] The working mechanism 6 includes a carriage assembly 6.1. The carriage assembly 6.1 includes a carriage body. On both sides of the carriage body, there are left and right baffles respectively. On the carriage body, there are front and rear side plates respectively. Among them, there is a U-shaped protruding groove 6.11 on the front side plate. Inside the carriage assembly 6.1, there is a propulsion oil cylinder 6.2. The output end of the propulsion oil cylinder 6.2 faces the U-shaped protruding groove 6.11 of the carriage body, and the other end of the propulsion oil cylinder 6.2 is fixed to the rear end of the carriage body. Thus, the output end of the propulsion oil cylinder 6.2 can protrude from the carriage assembly 6.1 through the U-shaped protruding groove 6.11, so that the length of the carriage assembly 6.1 can be greatly reduced.

[0042] The carriage assembly 6.1 is slidably connected to the power head 6.4 through a slide seat 6.3. The power head 6.4 is arranged on the slide seat 6.3. The propulsion oil cylinder 6.2 is connected to the slide seat 6.3 to push the power head 6.4. A gripper 6.5 is arranged at the end of the carriage assembly 6.1 for gripping the drill pipes.

[0043] The manipulator 4 is connected to one side of the support column 5 through a first rotary reducer 7, and the other side of the support column 5 is connected to the carriage assembly 6.1 of the working mechanism 6 through a second rotary reducer 8.

[0044] Working principle:

[0045] In this embodiment, in order to meet the market demand of medium and small coal mines, a small-volume automatic drilling rig suitable for medium and small coal mines is provided, with a more compact structure and reduced overall dimensions. According to the requirements of some medium and small coal mine customers, the overall dimensions of the main unit can be reduced to a transportation width of less than 1100 mm and a height of less than 1500 mm.

[0046] In this embodiment, the height of the main unit is reduced from the existing 1.87 m to 1.5 m, the height of the working platform is reduced by about 0.1 m, the height of the drill pipe frame is reduced by about 0.08 m, and the drill pipe frame adopts a sunken structure, with the height reduced by about 0.2 m; the length of the drilling rig is also shortened through the improvement of the carriage. When the existing carriage uses drill pipes of 0.8 m, the length can reach 2.6 - 2.7 m, while the length of the carriage of the present utility model can be shortened to 2.4 m when clamping 1 m drill pipes.

[0047] In order to make the height of the main unit body lower than 1500 mm, the original drill pipe box adopts a sunken structure, so that the bottom of the original drill pipe box "sinks" into the interior of the main unit frame, thereby reducing the overall height; the carriage structure of the working mechanism is also optimized, so that the carriage is shortened to the greatest extent without reducing the working angle range of the working mechanism.

[0048] The above are only specific application examples of the present utility model and do not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the rights of the present utility model.
