Description

Technical Field

[0001] The invention relates to the field of pipe seam anchor welding, and in particular to a pipe seam anchor welding positioning fixture. Background Art

[0002] Pipe-slit anchor is a reinforcement material used in geotechnical engineering. It is mainly used for supporting structures such as tunnels, slopes, and underground caverns. It is generally composed of a pipe body, a hoop, and a pad. The pipe body is generally composed of a steel pipe with pre-opened slits on it to allow the slurry to penetrate into the surrounding rock or soil during grouting. The hoop is a ring composed of steel bars connected end to end, which is sleeved and welded to one end of the pipe body (such as Figure 1 ), and the pad is set at the end of the anchor rod exposed to the rock surface to provide support and evenly transfer the anchoring force to the surrounding rock.

[0003] One of the necessary steps in producing pipe seam anchor rods is to put the hoop on the pipe fitting and weld the connection between the two. During this process, the pipe fitting needs to be fixed with a welding clamp. There are currently some problems in performing this step: when welding the connection between the pipe fitting and the hoop, in order to facilitate the removal of the hoop and pipe fitting connected as one after welding, the current clamping scheme generally fixes and clamps the pipe fitting from the outside. When the pipe fitting is clamped in this way, due to the thin wall thickness of the pipe fitting, the high temperature generated during the welding process can easily cause the pipe fitting to deform, thereby affecting the quality of the pipe seam anchor rod; before the welding work is carried out, it is usually necessary to manually put the hoop on the pipe fitting. Since the inner diameter of the hoop must be larger than the outer diameter of the pipe fitting, when the hoop is put on the pipe fitting, the hoop may have a certain inclination angle relative to the pipe fitting after the putting is completed. In this case, on the one hand, it will increase the difficulty of welding and reduce the welding efficiency. On the other hand, the welding may result in a cold weld, which will affect the connection strength between the two and ultimately affect the quality of the finished product.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

[0031] See also Figure 2 and Figure 3 A pipe seam anchor welding positioning fixture comprises a base plate, the upper end surface of the base plate and the left side thereof are connected to a supporting mechanism 1, the supporting mechanism 1 is connected to a center rod 2 extending in the left and right directions, the center rod 2 is connected to a connecting tube mechanism 3, the connecting tube mechanism 3 comprises a connecting disk 31, the connecting disk 31 is fixedly sleeved on the center rod 2, the right end surface of the connecting disk 31 and the upper position are rotatably connected to two long plates 32, a connecting piece 33 is rotatably connected between the two long plates 32 and on the right side thereof, a pressing ring 34 with an opening downward is fixedly connected to the lower end of the connecting piece 33, a short plate 35 is rotatably connected between the two long plates 32 and on the left side of the connecting piece 33, and a stabilizing component 36 is connected to the lower end of the short plate 35.

[0032] See also Figure 3 and Figure 4The stabilizing component 36 includes a positioning platform 361, and the positioning platform 361 includes a cylindrical section and a conical section. Two positioning platforms 361 are symmetrically arranged on the left and right. The conical sections of the two positioning platforms 361 are close to each other and are both sleeved on the center rod 2. The left positioning platform 361 is slidably connected to the center rod 2. The left end of the left positioning platform 361 is also fixedly connected to a round seat 362, which is slidably sleeved on the center rod 2 and rotatably connected to the short plate 35. The right positioning platform 361 is slidably connected to the center rod 2, and the bottoms of the cylindrical sections of the two positioning platforms 361 are connected to the limiting modules 363.

[0033] See also Figure 5 and Figure 6 The limiting module 363 includes a trapezoidal block 3631, and the side walls of the two positioning platforms 361 columnar sections and the lower sides are both connected with the trapezoidal blocks 3631 for upward and downward sliding cooperation. The ends with smaller widths of the two trapezoidal blocks 3631 are close to each other and are connected to the positioning platforms 361 through connecting springs 3632.

[0034] During the specific work, before putting in the pipe fitting, the right ends of the two long plates 32 are tilted upward, the angle between the short plate 35 and the center rod 2 is large, the round seat 362 and the left positioning platform 361 are located at the left end of the center rod 2. At this time, the distance between the two positioning platforms 361 is greater than the length of the pipe fitting. The staff will face the gap of the pipe fitting downward and align it with the center rod 2, and then put the pipe fitting on the center rod 2 from top to bottom, and then press the right end of the long plate 32 to rotate it into a horizontal state. In this process, the left positioning platform 361 slides to the right along the center rod 2, while pushing the pipe fitting to slide to the right along the center rod 2 and contacting the right positioning platform 361, and at the same time, the two ends of the pipe fitting are respectively slid along the tapered sections of the two positioning platforms 361 and put on the tapered sections of the two positioning platforms 361. At the same time, under the restriction of the two trapezoidal blocks 3631, the gap on the pipe fitting is always downward, so as to determine the starting welding point when the hoop is welded to the pipe fitting later.

[0035] See also Figure 3 , Figure 4 and Figure 5 A U-shaped support 4 is connected to the upper end surface of the bottom plate and on the right side. Two cross bars 5 are fixedly connected symmetrically between the two vertical sections of the U-shaped support 4. A U-shaped plate 6 is slidably connected to the two cross bars 5. Initially, the U-shaped plate 6 is located at the rightmost end of the two cross bars 5. A sleeve mechanism 7 for sleeve-fitting the hoop in a fixed position on the pipe body is connected to the U-shaped plate 6. The right end of the sleeve mechanism 7 is connected to an external cylinder that pushes it to move to the left.

[0036] See also Figure 3 , Figure 4 and Figure 5The support mechanism 1 includes a No. 1 connecting plate 11, which is fixedly connected to the bottom plate. A vertical rod 12 is fixedly connected to the upper end surface of the No. 1 connecting plate 11 and located at the center. The upper end of the vertical rod 12 is rotatably connected to a No. 2 connecting plate 13. The No. 2 connecting plate 13 is connected to the No. 1 connecting plate 11 through a No. 1 torsion spring 14. The upper end surface of the No. 2 connecting plate 13 is symmetrically fixedly connected to two vertical frames 15, and the two vertical frames 15 are commonly fixedly connected to a center rod 2.

[0037] During the specific work, after the pipe fitting is limited by the two positioning tables 361, the staff places a hoop on the sleeve mechanism 7, and then drives the sleeve mechanism 7 and the U-shaped plate 6 to move to the left synchronously through the external cylinder. When the U-shaped plate 6 moves to the leftmost side, the sleeve mechanism 7 continues to operate to first push the pipe fitting to the left by a certain distance, so that the left end of the pipe fitting contacts the round seat 362, and then the hoop on the leftmost side is sleeved on the right end of the pipe fitting, and then the U-shaped plate 6 and the sleeve mechanism 7 are moved to the right and reset by the external cylinder, and then the connection between the hoop and the pipe fitting is welded by the external welding arm.

[0038] After welding is completed, first push the right end of the long plate 32 upward, drive the left positioning platform 361 to move to the left and reset through the short plate 35, and then push the pipe backward, so that the second connecting plate 13, the vertical frame 15 and the center rod 2 rotate to the right synchronously, so that the welded pipe can be removed from the center rod 2. After removal, the second connecting plate 13 is reset to the initial position under the action of the No. 1 torsion spring 14 to facilitate the next operation.

[0039] See also Figure 7 The sleeve mechanism 7 includes a support plate 71. Two support plates 71 are symmetrically fixedly connected to the top of the U-shaped plate 6. A moving component 72 is commonly connected to the support plate 71 and the U-shaped plate 6. A driving component 73 is commonly connected to the upper end surfaces and the right sides of the two support plates 71. A ring component 74 is connected to the upper end surfaces and the left sides of the support plates 71. The two ring components 74 are both connected to the driving component 73. A positioning component 75 is connected to the upper end surface of the support plate 71 and located on the left side of the ring component 74.

[0040] See also Figure 7 and Figure 8The object moving component 72 includes a transmission roller 721, and two transmission rollers 721 are symmetrically arranged on the left and right and are rotatably connected between the two vertical sections of the U-shaped plate 6. Two pulleys are symmetrically connected to the two transmission rollers 721, and the two symmetrical pulleys are connected through a belt 722 for transmission. The two belts 722 are commonly connected with a feeding module 723 for placing a hoop. The front end roller shaft head of the left transmission roller 721 and the U-shaped plate 6 are commonly connected with a ratchet pawl that enables the transmission roller 721 to rotate unidirectionally. The end surfaces of the two support plates 71 that are close to each other are fixedly connected to a limiting frame 724, and the two limiting frames 724 are symmetrical front and back and cooperate with the hoop.

[0041] See also Figure 8 The feeding module 723 includes a connecting rod 7231, and the outer surface of the belt 722 is evenly and fixedly connected with a plurality of connecting rods 7231 along its length direction. The connecting rods 7231 on the two belts 722 correspond to each other one by one, and the two corresponding connecting rods 7231 are fixedly connected by a round rod 7232. A rectangular plate 7233 is fixedly connected to the side wall of the round rod 7232 and on the side away from the belt 722.

[0042] During specific operation, the gap between two adjacent round rods 7232 cooperates with the front and rear limiting frames 724 to form a placement area for placing the hoop. After limiting the pipe by two positioning platforms 361, the staff places the hoop in the placement area, and then drives the driving assembly 73 through an external cylinder to move the U-shaped plate 6 to the left.

[0043] See also Figure 7 The driving assembly 73 includes a connecting seat 731, and the connecting seat 731 is fixedly connected to the upper end surface of the support plate 71 and on the right side. A push rod 732 is connected to the connecting seat 731 so as to slide left and right. The right ends of the two push rods 732 are commonly fixedly connected to a push plate 733. The right side of the push plate 733 is connected to the external cylinder. The left end of the push rod 732 is connected to a ring assembly 74. The push rod 732 and the connecting seat 731 are commonly connected with a delay module 734; the delay module 734 includes a rod sleeve 7341, and the rod sleeve 7341 is fixedly sleeved on the push rod 732 and is located on the right side of the connecting seat 731. The rod sleeve 7341 is connected to the connecting seat 731 through a push-pull spring 7342.

[0044] See also Figure 8 , Fig. 9 and Fig.10When the cam 720 is in the closed position, the stopper 742 is in the closed position, and the stopper 743 is in the closed position, so that the cam 720 can be turned to the open position, and the stopper 743 can be turned to the open ...

[0045] During specific operation, the push plate 733 is pushed to the left by the external cylinder. In the initial stage of movement, the push-pull spring 7342 is in a compressed state, and then when the push plate 733 moves to the left, the rod sleeve 7341 and the push-pull spring 7342 push the connecting seat 731, the support plate 71 and the U-shaped plate 6 to move to the left synchronously. At this time, the push rod 732 and the connecting seat 731 are in a relatively static state. When the U-shaped plate 6 moves to the leftmost end, as the push plate 733 continues to move to the left under the push of the external cylinder, the push-pull spring 7342 is further compressed, and then the push rod 732 slides to the left relative to the connecting seat 731, driving the push block 744 to slide to the left along the slide groove 741 synchronously. The three hoops from left to right are named No. 1 hoop, No. 2 hoop and No. 3 hoop respectively. The movement of the push block 744 to the left will push the No. 1 hoop to the left.

[0046] When the No. 1 hoop moves to the left, it pushes the round rod 7232 on its left side to move to the left. Since the round rod 7232 is located at the turning point above the belt 722, as the No. 1 hoop moves to the left, the round rod 7232 on its left side moves along the semicircular trajectory with the belt 722, thereby causing the left end of the leftmost hoop to lose its limit. At the same time, in the process of clamping the pipe by the two positioning platforms 361, the pipe may move too far to the right due to the surface friction of the positioning platforms 361. When this happens, the round rod 7232 on the left side of the No. 1 hoop moves with the belt 722 and pushes the pipe to the left through the rectangular plate 7233 thereon, so that the left end of the pipe hits the round seat 362, thereby further adjusting the position of the pipe. The No. 1 hoop will eventually break away from the belt 722 under the drive of the push block 744, and the No. 2 hoop will move with the belt 722 and the round rod 7232 to the previous position of the No. 1 hoop, and the No. 3 hoop will move to the previous position of the No. 2 hoop.

[0047] See also Fig.10The positioning assembly 75 includes a mounting rod 751, and the mounting rod 751 is fixedly connected to the upper end surface of the support plate 71 and located on the right side of the slider 742. The mounting rod 751 is rotatably connected to a support plate 752. Initially, the front and rear support plates 752 are both in an inclined state, and the distance between the two support plates 752 increases from left to right. The support plate 752 and the mounting rod 751 are fixedly connected by a No. 2 torsion spring 753. The left ends of the slider 742 and the push block 744 are fixedly connected to a support rod 754 that cooperates with the support plate 752.

[0048] See also Figure 8-Figure 10 When the slider 742 is in operation, the push rod 754 on the slider 742 first contacts the push plate 752, pushing the push plate 752 to rotate. When the two push plates 752 rotate to be on the same straight line front and back, the push rod 754 on the push block 744 also happens to abut on the push plate 752. The push block 744 and the push plate 752 work together to clamp the No. 1 hoop between the two, so that the No. 1 hoop can be in a vertical state. After that, when the slider 742 continues to move to the left, the push block 744 can push the No. 1 hoop to be set at the specified position on the pipe fitting.

[0049] After that, the push plate 733 is driven to move to the right and reset by an external cylinder. In the initial stage of resetting, the push plate 733 moves to the right and drives the push rod 732 to move to the right, so that the slider 742 slides to the right along the slide groove 741. During this process, the abutment rod 754 on the slider 742 cancels the abutment against the abutment plate 752, so that the abutment plate 752 rotates and resets under the action of the No. 2 torsion spring 753 to release the limit on the left side of the No. 1 hoop sleeved on the pipe fitting. During this process, the push-pull spring 7342 is still in a compressed state, and always applies a leftward force to the support plate 71 and the U-shaped plate 6 through the connecting seat 731. The U-shaped plate 6 is still located at the leftmost side of the horizontal bar and is in a stationary state.

[0050] When the slider 742 moves to the right, the slider 743 and the push block 744 are moved to the right synchronously, during which the inclined surface of the right end of the push block 744 will contact the second hoop. At this time, the return spring 746 is compressed, and the push block 744 moves away from the limit frame 724 to make way. Under the action of the ratchet pawl mechanism, the belt 722 can only be fed counterclockwise. Therefore, the push block 744 will pass over the second hoop as the slider 742 continues to slide to the right. When the slider 742 moves to the rightmost end of the slide slot 741, the push block 744 is away from the slider 742 under the action of the return spring 746. At this time, the push block 744 is just located between the second hoop and the third hoop. After that, when the push rod 732 pulls the slider 742 to move to the right, it will drive the support plate 71 and the U-shaped plate 6 to move to the right synchronously through the slider 742, so as to facilitate welding and removing the pipe fittings and hoop connected as one after welding.
