Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of exploration and drilling in deep earth, deep sea, deep space and polar regions, and particularly relates to a continuous pipe pressing and anti-disengagement mechanism of a 3D printing type vehicle-mounted continuous pipe storage and transportation system. BACKGROUND

[0002] Exploration and drilling technology is an important means for humans to obtain various mineral resources and soil and rock physical data from the earth and extraterrestrial planets. At present, the energy transmission of traditional exploration and drilling is mainly realized through continuous cables and fluid pipelines, and the equipment for storing and transporting these long continuous pipes is mainly a winch. However, although the winch has excellent characteristics such as simple structure and large capacity, it has serious deficiencies, such as that the conductive or flow-through slip ring is prone to failure, and that the mutual extrusion and biting between adjacent pipes in each layer are prone to damage, which affects the normal work and safety of the continuous pipe transmission terminal execution component. Therefore, the inventor proposes a "continuous pipe large-capacity storage and transportation device", which is detailed in patent number CN217327242U, effectively solving the above problems.

[0003] However, the existing continuous pipe storage and transportation device still has deficiencies. It has no protection mechanism when storing and extracting continuous pipes, which poses a safety hazard, and the storage and extraction efficiency is low. Specifically, the continuous pipe is composed of two layers of stainless steel pipes with a certain bending radius, and several cables and signal lines are arranged in the annulus between the inner and outer pipes. Therefore, when storing and storing the continuous pipe using the existing continuous pipe storage and transportation device, the continuous pipe needs to be bent and stored in the continuous pipe storage sleeve. Since the storage sleeve structure is circular and its radius is greater than the bending radius of the continuous pipe, the continuous pipe always maintains a large elastic restoring force after being stored in the sleeve. If an operation error occurs during the storage of the continuous pipe, causing the continuous pipe to disengage from the sleeve, damage to personnel or equipment may occur during the deformation recovery process. In order to avoid the occurrence of the above accidents, it is necessary to reduce the storage speed of the continuous pipe to a certain extent, and special personnel are needed to check whether the continuous pipe is stored in place in real time, so as to prevent safety accidents. Therefore, it is necessary to invent a continuous pipe pressing and anti-disengagement mechanism for a 3D printing type vehicle-mounted continuous pipe storage and transportation system. SUMMARY

[0004] The purpose of the present application is to provide a continuous pipe pressing and anti-disengagement mechanism for a 3D printing type vehicle-mounted continuous pipe storage and transportation system, which aims to solve the technical problem of safety hazards existing in the storage and extraction of continuous pipes by the existing continuous pipe storage and transportation device, and to improve the storage efficiency.

[0019] The continuous pipe pressing-in and anti-disengaging mechanism 2 is fixedly installed on the continuous pipe storage sleeve 1 as a whole, and there are 4 sets of symmetric distribution, and when working, each set cooperates with each other to complete the action of pressing the continuous pipe into the continuous pipe storage sleeve 1 and preventing the continuous pipe from disengaging from the continuous pipe storage sleeve 1;

[0020] The horizontal displacement driving motor 201 and the sliding block mounting seat 202 are fixedly connected to the second mounting position 102 on the continuous tube storage sleeve 1. The sliding block mounting seat 202 is provided with a first trapezoidal slide 217, a first rectangular slide 218 and a second rectangular slide 219. The first sliding block 203 is provided with a first trapezoidal protrusion 214, a first rectangular protrusion 215 and a second rectangular protrusion 216. The first trapezoidal slide 217, the first rectangular slide 218, the first trapezoidal protrusion 214 and the first rectangular protrusion 215 are symmetrically distributed in two groups. The first sliding block 203 is slidingly connected to the sliding block mounting seat 202. The first trapezoidal protrusion 214 is fitted with the first trapezoidal slide 217. The first rectangular protrusion 215 is fitted with the first rectangular slide 218. The second rectangular protrusion 216 is fitted with the second rectangular slide 219. The first rectangular protrusion 215 is provided with a first roller mounting groove 220. The first roller 221 is arranged in the first roller mounting groove 220 and is rotationally connected to the first rectangular protrusion 215. The second rectangular protrusion 216 is provided with a first lead screw through hole 222. The first lead screw 204 is arranged in the second rectangular slide 219. The end of the first lead screw 204 is rotationally connected to the sliding block mounting seat 202. The first end of the first lead screw 204 is coaxially fixedly connected to the horizontal displacement driving motor 201. The first lead screw 204 is threadedly connected to the first lead screw through hole 222. The horizontal displacement driving motor 201 drives the first sliding block 203 to reciprocate. In actual work, the first trapezoidal protrusion 214 and the first trapezoidal slide 217 are arranged to limit the freedom of the first sliding block 203 in other directions, and only one direction of horizontal movement is reserved. The first roller 221 is arranged to reduce the frictional resistance generated when displacement occurs.

[0021] Please refer to Figure 5 As shown, the motor mounting plate 205 is fixedly connected to the first sliding block 203. The vertical displacement driving motor 206 and the elevator 207 are fixedly connected to the motor mounting plate 205. The vertical displacement driving motor 206 and the elevator 207 are coaxially connected. The elevator lead screw 208 is threadedly connected to the elevator 207. The pressure head 209 is fixedly connected to the elevator lead screw 208. During work, the vertical displacement driving motor 206 drives the elevator 207, and then drives the elevator lead screw 208 to move up and down, and drives the pressure head 209 to complete the action of pressing the continuous tube into the continuous tube storage sleeve 1.

[0022] Please refer to Figure 1 、 Figure 3 、 Figure 5As shown, the motor mounting frame 210 is fixedly connected to the first mounting position 101, the baffle driving motor 211 is fixedly connected to the motor mounting frame 210, the first plane thrust bearing 212 is fixedly connected to the motor mounting frame 210, the baffle 213 is in contact with the first plane thrust bearing 212 and is fixedly connected to the rotating shaft of the baffle driving motor 211. During work, the baffle 213 is driven by the baffle driving motor 211 to perform sector motion, thereby forming an obstacle above the continuous tube storage sleeve 1, so as to prevent the continuous tube in the continuous tube storage sleeve 1 from separating from the continuous tube storage sleeve 1 and causing a safety accident.

[0023] Furthermore, when the first screw rod 204 is installed in the second rectangular slide 219 and the first roller 221 is connected in the first roller mounting groove 220, appropriate bearings are correspondingly arranged in the mounting hole positions, so as to reduce the frictional resistance generated when the first roller 221 and the first screw rod 204 rotate.

[0024] During work, the first sliding block 203 reciprocates under the driving of the horizontal displacement driving motor 201 and the first screw rod 204, and the displacement stroke arranged by the first sliding block 203 can fully meet the pressing-in requirements of the continuous tube at different positions.

[0025] Working principle and use process of the present application:

[0026] In actual work, the continuous tube pressing-in and anti-separation mechanism 2 is installed on the continuous tube storage sleeve 1 and is symmetrically distributed in four groups. Taking the storage of continuous tubes as an example, when the tube storage and taking mechanism 4 moves close to a group of continuous tube pressing-in and anti-separation mechanisms 2, first, the baffle 213 is driven by the baffle driving motor 211 to move and open the path through which the continuous tube passes, when the tube storage and taking mechanism 4 drives the continuous tube to move away from the group of continuous tube pressing-in and anti-separation mechanisms 2, the baffle 213 is driven by the baffle driving motor 211 to move and close the path through which the continuous tube passes, then the sliding block mounting seat 202 is driven by the horizontal displacement driving motor 201 to move, so that the pressing head 209 is just located above the continuous tube, then the elevator 207 is driven by the vertical displacement driving motor 206, thereby driving the elevator screw rod 208 and the pressing head 209 to move downward, and the continuous tube is pressed into the continuous tube storage sleeve 1. The tube taking process is opposite to the tube storage process, but during tube taking, only the baffle 213 needs to be opened in time when the continuous tube passes, and the baffle 213 needs to be closed in time when the continuous tube moves away.
