Description

Technical Field

[0001] The present invention relates to the technical field of rotary drilling rigs, and in particular to an efficient deep-hole rotary drilling rig. Background Art

[0002] A rotary drilling rig is a kind of engineering construction machinery, mainly used for pile foundation engineering in infrastructure construction such as buildings, bridges, railways, and highways.

[0003] When the rotary drilling rig is in use, the power head drives the drill pipe to rotate, so that the drill bucket installed on the drill pipe rotates. At the same time, the pressure provided by the hydraulic device is also transmitted to the drill bucket through the drill pipe, and then the drill bucket realizes the cutting and crushing of the rock and soil, so that the rock and soil enter the drill bucket. When the drill bucket reaches the specified depth, the drill pipe is lifted to bring the drill bucket to the ground. Then, the operator on the vehicle uses the control system to move the drill bucket to the designated soil unloading position, and uses the hydraulic device to lift the drill bucket upward. After that, the switch pipe on the drill bucket touches the cushion ring under the power head, and the bottom plate of the drill bucket opens to unload the rock and soil. Then, the operator uses the control system on the vehicle to press the open end of the bottom plate against the ground, and then moves the drill pipe downward to close the bottom plate and clamp it to the drill bucket, and then starts the next working cycle. For this kind of rotary drilling rig, the opening and closing method of the drill bucket is relatively cumbersome and is easily affected by the rock and soil. Sometimes, after cleaning the clamping part, the bottom plate can be closed to the drill bucket, which affects the rotary drilling efficiency.

[0004] The inventor of the present invention at least found the following problems during the implementation of this embodiment:

[0005] For the existing rotary drilling rigs, the opening and closing of the drill bucket are relatively cumbersome, and the rotary drilling efficiency is relatively low. Summary of the Invention

[0006] The purpose of the present invention is to provide an efficient deep-hole rotary drilling rig, which solves the technical problems that for the existing rotary drilling rigs, the opening and closing of the drill bucket are relatively cumbersome and the rotary drilling efficiency is relatively low.

[0017] Beneficial effects: When using the high-efficiency deep-hole rotary drilling rig provided by the present invention, after the operator moves the rotary drilling rig body to the designated position and buries the casing, the operator operates the rotary drilling rig body to make the drill bucket located at the center position of the casing. Then, the drill pipe of the rotary drilling rig body is driven to rotate, the drill pipe drives the cylinder body to rotate, the cylinder body drives the drill claw assembly to rotate, and the drill bit breaks the rock and soil. As the drill claw assembly rotates, the collecting member scrapes the broken rock and soil into the soil inlet, and then enters the cylinder body. When the cylinder body is filled with rock and soil, the operator operates the rotary drilling rig body to move the drill bucket out of the ground and move it to the designated position. Then, the motor is started, the motor drives the turbine to rotate, the turbine drives the worm to rotate, so that the worm leaves the limit hole. Then, the drill bucket is rotated. The drill claws are subjected to centrifugal force and the gravity of the rock and soil, and the drill claws open. After the rock and soil are unloaded from the cylinder body, the drill claws are subjected to their own gravity and return to their original positions. The motor is started, the motor drives the turbine to rotate, the turbine drives the worm to rotate, and the worm returns to the limit hole to limit the drill claws. Among them, the motor driving the turbine to rotate and moving the drill bucket above the casing can be carried out simultaneously. Therefore, for this high-efficiency deep-hole rotary drilling rig, the opening and closing of the drill bucket are relatively simple, and the rotary drilling efficiency is relatively high.

[0034] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] This embodiment provides an efficient deep hole rotary drilling rig. Figure 1-6 As shown, it includes a rotary drilling rig body 100 and a drill bucket 200; the drill bucket 200 includes a barrel 210, a drill claw assembly 220 and a switch 230; the barrel 210 is transmission-connected to the rotary drilling rig body 100; the drill claw assembly 220 includes a plurality of drill claws 221 and a plurality of drill bits 222; when the plurality of drill claws 221 are in a closed state, the whole is cylindrical; the drill claw 221 includes a side plate 2211, a bottom plate 2212, a collecting piece 2213 and a limiting block 2214; the side plate 2211 and the bottom plate 2212 are integrally formed, the bottom plate 2212 is provided with a soil inlet 225, the collecting piece 2213 is provided with a soil inlet 225, and the collecting piece 2214 is provided with a soil inlet 225. 213 is installed below the base plate 2212, the limit block 2214 is rotatably connected to the cylinder 210, the limit block 2214 is provided with a limit hole 2215, and the drill bit 222 is installed at the bottom of the collecting member 2213; the switch member 230 includes a motor 231, a turbine 232 and a worm 233; the motor 231 is installed on the cylinder 210, and it is electrically connected to the rotary drilling rig body 100, the turbine 232 is installed on the output shaft of the motor 231, the worm 233 is adapted to the turbine 232, and it is penetrated through the cylinder 210, and the output end of the worm 233 is adapted to the limit hole 2215.

[0036] Specifically, the rotary drilling rig body 100 includes an operating system, a power system, a traveling system, and a drilling system (such as a guide rod and a drill pipe). These systems work together to ensure that the rotary drilling rig body 100 completes the drilling operation. The drill bucket 200 is the terminal execution element of the rotary drilling rig body 100. The cylinder body 210 is used to hold the rock and soil drilled by the drill claw assembly 220, and at the same time provides power for the drill claw assembly 220. There are four drill claws 221 and sixteen drill bits 222. Every four drill bits 222 form a group, and each group is installed on a collecting member 2213. When the drill claws 221 are in the closed state, the whole is in a cylindrical shape to prevent soil leakage; the drill claws 221 are used to break and collect rock and soil. The bottom plate 2212 and the side plate 2211 are integrally formed to ensure the overall connection strength of the drill claws 221. The inlet is used to allow rock and soil to enter the cylinder body 210. The collecting member 2213 is used to scrape the rock and soil drilled by the drill bits 222. The limiting block 2214 is used to rotatably connect the side plate 2211 to the cylinder body 210. The limiting hole 2215 is used to limit the position of the limiting block 2214 to prevent the drill claws 221 from separating after being affected by centrifugal force. The switch member 230 is used to control the closing of the drill claw assembly 220. The motor 231 drives the turbine 232 to rotate, and the turbine 232 drives the worm 233 to rotate, so that the worm 233 moves up or down, thereby leaving or inserting into the limiting hole 2215, realizing the control of the opening or closing of the drill claw assembly 220. During use, after the operator moves the rotary drilling rig body 100 to the designated position, the casing is buried. The operator operates the rotary drilling rig body 100 to make the drill bucket 200 located at the center position of the casing. Then, the drill pipe of the rotary drilling rig body 100 is driven to rotate. The drill pipe drives the cylinder body 210 to rotate, and the cylinder body 210 drives the drill claw assembly 220 to rotate. The drill bits 222 break the rock and soil. As the drill claw assembly 220 rotates, the collecting member 2213 scrapes the broken rock and soil into the soil inlet 225, and then enters the cylinder body 210. When the cylinder body 210 is filled with rock and soil, the operator operates the rotary drilling rig body 100 to move the drill bucket 200 out of the ground and to the designated position. Then, the motor 231 is started. The motor 231 drives the turbine 232 to rotate, and the turbine 232 drives the worm 233 to rotate, so that the worm 233 leaves the limiting hole 2215. Then, the drill bucket 200 is rotated. The drill claws 221 are affected by centrifugal force and the gravity of the rock and soil, and the drill claws 221 open. After the rock and soil are unloaded from the cylinder body 210, the drill claws 221 return to their original positions due to their own gravity. The motor 231 is started. The motor 231 drives the turbine 232 to rotate, and the turbine 232 drives the worm 233 to rotate, so that the worm 233 returns to the limiting hole 2215 to limit the drill claws 221. Among them, the motor 231 driving the turbine 232 to rotate and moving the drill bucket 200 above the casing can be carried out simultaneously.

[0037] In this embodiment, the collecting member 2213 is provided with an input groove 2216, and the input groove 2216 is communicated with the soil inlet 225.

[0038] Specifically, the setting of the input slot 2216 increases the area of the soil inlet 225 and improves the efficiency of the rock and soil entering the cylinder 210.

[0040] Specifically, the soil blocking member 2217 is used to reduce the situation of the rock and soil in the cylinder 210 falling downward, and the arc-shaped groove 2218 is used to facilitate the smooth entry of the rock and soil into the cylinder 210.

[0041] In this embodiment, the collecting member 2213 is provided with an inclined surface 2219, and the drill bit 222 is installed on the inclined surface 2219.

[0042] Specifically, the inclined surface 2219 inclines from the edge of the bottom plate 2212 to the center of the bottom plate 2212 from thin to thick, so that the drill bit 222 can concentrate on drilling through the center of the rock and soil.

[0043] In this embodiment, an arc-shaped limiting plate 211 is welded inside the cylinder 210, and the outer wall of the arc-shaped limiting plate 211 abuts against the inner wall of the side plate 2211.

[0044] Specifically, the arc-shaped limiting plate 211 is used to limit the angle of inward rotation of the side plate 2211 and prevent the side plates 2211 from colliding with each other.

[0045] In this embodiment, a reinforcing plate 223 is installed on the inner wall of the side plate 2211, and the reinforcing plate 223 is provided with an arc-shaped portion 224.
