Description

Technical Field

[0001] The invention belongs to the technical field of orifice pipe processing, and in particular relates to a drainage grouting orifice pipe processing device. Background Art

[0002] During the drilling and curtain grouting process of high-temperature tunnels, high-temperature hot water is prone to sudden surges, which poses an extremely high safety risk. It causes a sudden increase in temperature and humidity on site, making normal construction operations impossible, taking up tunnel construction time, and making it difficult to ensure the safety of on-site construction.

[0003] A construction process using an "L-shaped" branch-shaped drainage and grouting orifice device has now emerged. Because it fits the orifice, it reduces the risk of high-temperature hot water surges during high-temperature hot water tunnel construction and improves construction safety.

[0004] Since the above-mentioned branch-shaped drainage and grouting type orifice pipe has a branch pipe at its end, and the branch pipe needs to be welded to the orifice pipe at a required angle, there are different welding installation angles during the processing process, which leads to welding difficulties and the welding angle is prone to deviation. Summary of the invention

[0005] The purpose of the present invention is to provide a drainage grouting orifice pipe processing device to solve the problems of welding difficulties and easy deviation of welding angles due to different welding installation angles during the processing of branch-shaped drainage and grouting orifice pipes.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A drainage grouting orifice pipe processing device comprises a base, a plurality of frames are mounted on the base, a clamping mechanism is mounted on the frames, and the clamping mechanism is used to clamp the orifice pipe to be processed;

[0008] A limiting sleeve can be detachably mounted on the base, an annular plate is arranged outside the limiting sleeve, the annular plate is rotatably mounted on the base, a guiding mechanism is mounted on the annular plate, and the guiding mechanism is used to guide the branch pipe to be welded.

[0009] Preferably, the clamping mechanism comprises:

[0010] A T-shaped rod, the end of which passes through the frame;

[0011] A clamping member, the clamping member is fixedly connected to the end of the T-shaped rod, and the clamping member is arranged in an arc-shaped structure;

[0012] A return spring, the return spring is located between the clamping member and the frame, and the return spring is sleeved on the T-bar;

[0013] The elastic force of the return spring pushes the two symmetrically distributed clamping members to close together so as to clamp the orifice pipe to be processed.

[0014] Preferably, the guiding mechanism comprises:

[0015] A ball joint seat, wherein the ball joint seat is mounted on the annular plate, and a plurality of ball joint seats are provided;

[0016] A guide ball is hinged on a ball joint seat, a guide through hole is provided on the guide ball, the branch pipe is inserted into the guide through hole, and the branch pipe is freely rotated through the guide ball until it contacts the orifice pipe to be processed.

[0017] Preferably, an electric lifting column is connected between the ball joint seat and the annular plate, and the height of the ball joint seat and the guide ball is adjusted by the electric lifting column.

[0018] Preferably, an exit groove is provided on the guide ball, the exit groove is connected to the guide through hole, an elastic layer is provided on the outer side of the guide ball, and an elastic pad with a thickness gradually decreasing from the inside to the outside is fixed on the inner wall of the exit groove.

[0019] Preferably, a laser emitter is installed at one end of the guide through hole, and an angle sensor is installed at the other end of the guide through hole.

[0020] Technical effects and advantages of the present invention: Compared with the prior art, the drainage grouting orifice pipe processing device proposed by the present invention has the following advantages:

[0021] 1. The present invention fixes the upper and lower ends of the orifice pipe to be processed by limiting, and then rotates the annular plate as needed to make the guide mechanism on the annular plate correspond to the connecting hole on the orifice pipe to be processed. The rotatably installed annular plate can change its position in real time, thereby facilitating welding and installation work at different positions on the orifice pipe to be processed, and the operation is highly convenient.

[0022] 2. The present invention inserts the branch tube into the guide through hole on the guide ball first, then holds the branch tube to drive the guide ball to preliminarily adjust the angle until the branch tube roughly corresponds to the connecting hole, and then pushes the end of the branch tube to penetrate and extend out of the guide through hole until it contacts and corresponds with the connecting hole. The free floating rotation relationship between the guide ball and the ball joint seat is utilized to perform floating adjustment when welding and installing the branch tube, so that the welding and installation of the branch tube is more convenient and the operation has a high fault tolerance rate.

[0023] 3. The present invention installs a laser emitter at the port of the guide through hole. Since the laser emitter is parallel to the central axis of the guide through hole, when the guide ball rotates, the laser emitted by the laser generator will deflect accordingly, while the angle scale remains unchanged. Therefore, the staff can judge whether the angle of the branch pipe is accurate based on whether the position of the laser beam on the angle scale changes. Therefore, the installation angle of the branch pipe can be monitored in real time during the entire process of branch pipe installation to ensure that the branch pipe is accurately connected to the connecting hole at an angle.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present invention provides Figure 1-4 A drainage grouting orifice pipe processing device is shown,

[0031] It comprises a base 1, on which two frames 2 are mounted, on which clamping mechanisms 3 are mounted, the two clamping mechanisms 3 are symmetrically distributed, and the clamping mechanisms 3 are used to clamp an orifice pipe 4 to be processed;

[0032] A limiting sleeve 5 is also fixed on the base 1 by threads or bolts, an annular plate 6 is provided on the outer side of the limiting sleeve 5, the annular plate 6 is rotatably mounted on the base 1, a guiding mechanism 7 is installed on the annular plate 6, and the guiding mechanism 7 is used to guide the branch pipe 8 to be welded.

[0033] Furthermore, the clamping mechanism 3 comprises:

[0034] A T-shaped rod 31, the end of which passes through the frame 2;

[0035] A clamping member 32, wherein the clamping member 32 is fixedly connected to the end of the T-shaped rod 31, and the clamping member 32 is configured to be an arc-shaped structure;

[0036] A return spring 33, wherein the return spring 33 is located between the clamping member 32 and the frame 2, and the return spring 33 is sleeved on the T-shaped rod 31;

[0037] The elastic force of the return spring 33 pushes the two symmetrically distributed clamping members 32 to close together to clamp the orifice pipe 4 to be processed. In order to solve the problem that the branch drainage and grouting type orifice pipe 4 is difficult to weld due to different welding installation angles during the processing, and the welding angle is prone to deviation, the present invention sets a clamping mechanism 3 and a guide mechanism 7 to cooperate, so as to achieve the purpose of floating adjustment of the branch pipe 8, making the welding installation between the branch pipe 8 and the orifice pipe 4 more convenient.

[0038] When in use, the worker first pulls the T-bars 31 on both sides to make the clamping parts 32 that were originally closed move away from each other, puts the orifice tube 4 to be processed in, and then relaxes the T-bars 31. The clamping parts 32 are pushed to reset again under the elastic force of the reset springs 33, so that the two relative clamping parts 32 clamp the orifice tube 4. Since the limiting sleeve 5 can be selected according to the size of the orifice tube 4 to be processed, the bottom of the orifice tube 4 to be processed is inserted into the limiting sleeve 5, and the upper and lower ends of the orifice tube 4 to be processed are both limited and fixed. At this time, the annular plate 6 is rotated as needed to make the guide mechanism 7 on the annular plate 6 correspond to the connecting hole on the orifice tube 4 to be processed. The rotatably installed annular plate 6 can change its position in real time, thereby facilitating welding and installation work at different positions on the orifice tube 4 to be processed, and the operation is highly convenient.

[0039] Furthermore, the guiding mechanism 7 comprises:

[0040] A ball joint seat 71, wherein the ball joint seat 71 is mounted on the annular plate 6, and a plurality of ball joint seats 71 are provided;

[0041] The guide ball 72 is hinged on the ball joint seat 71, and a guide through hole 73 is provided on the guide ball 72. The branch pipe 8 is inserted into the guide through hole 73 and freely rotates through the guide ball 72 until it contacts the orifice pipe 4 to be processed.

[0042] Furthermore, an electric lifting column 74 is connected between the ball joint seat 71 and the annular plate 6 , and the height of the ball joint seat 71 and the guide ball 72 is adjusted by the electric lifting column 74 .

[0043] Furthermore, the guide ball 72 is provided with an exit groove 75, which is connected to the guide through hole 73. An elastic layer 11 is provided on the outer side of the guide ball 72, and an elastic pad 12 with a thickness gradually decreasing from the inside to the outside is fixed on the inner wall of the exit groove 75. The elastic layer 11 is provided so that there is a certain damping between the guide ball 72 and the ball joint seat 71, so that the guide ball 72 is difficult to rotate by itself after the initial angle adjustment, thereby facilitating the installation operation of the guide ball 72 and the branch pipe 8. When the guide mechanism 7 is adjusted to the position with the annular plate 6, the branch pipe 8 is first inserted into the guide through hole 73 on the guide ball 72, and then the branch pipe 8 is held to drive the guide ball 72 to adjust the angle initially, until the branch pipe 8 is roughly aligned with the connecting hole, and then the end of the branch pipe 8 is pushed through and extends out of the guide through hole 73 until it contacts and corresponds with the connecting hole. If it is just aligned, it is only necessary to tighten the fixing bolts threadedly installed on the outer side of the hinge seat. When the fixing bolts are tightened, the end will be squeezed onto the guide ball 72 and exert pressure on the guide ball 72, so that the guide ball 72 is restricted from rotating. The worker only needs to operate the welding equipment to weld the branch pipe 8 to the orifice pipe 4;

[0044] If there is a slight deviation between the branch pipe 8 and the connecting hole, swing the branch pipe 8 horizontally until the branch pipe 8 is aligned with the connecting hole, and then perform locking and subsequent welding work;

[0045] If there is an upward and downward deviation between the branch pipe 8 and the connecting hole, the electric lifting column 74 is controlled to push the entire hinge seat and the guide ball 72 up or down while keeping the angle of the branch pipe 8 unchanged, until the branch pipe 8 and the connecting hole are aligned. Through the free floating rotation relationship between the guide ball 72 and the ball hinge seat 71, floating adjustment can be performed when welding and installing the branch pipe 8. The high degree of freedom of the guide adjustment makes the welding and installation of the branch pipe 8 more convenient and has a high fault tolerance rate in operation.

[0046] After welding is completed, the orifice tube 4 and the branch tube 8 of the integrated structure can be directly removed, and the design of the exit groove 75 can facilitate the branch tube 8 to exit from the guide ball 72. The elastic pad 12 with a gradually decreasing thickness arranged in the exit groove 75 is used to limit the branch tube 8 to be located in the guide through hole 73. When it is necessary to exit, the elastic pad 12 can be forcibly compressed to deform.

[0047] Furthermore, a laser emitter 9 is installed at one end of the guide through hole 73, and an angle sensor 10 is installed at the other end of the guide through hole 73. Since the angle of the branch pipe 8 for welding and installation is limited, in order to ensure the accuracy of the installation angle of the branch pipe 8, the present invention installs a laser emitter 9 at the end of the guide through hole 73. The laser emitter 9 is parallel to the central axis of the guide through hole 73. When the guide ball 72 rotates, the laser emitted by the laser emitter 9 will deflect accordingly. Therefore, the staff can preliminarily judge whether the angle of the branch pipe 8 is accurate based on the position of the laser beam on the orifice pipe 4, and then cooperate with the angle sensor 10 to monitor the installation angle of the branch pipe 8 in real time during the whole process of the branch pipe 8 installation, so as to ensure that the branch pipe 8 is connected to the connection hole at an accurate angle.
