Description

Technical Field

[0001] The invention relates to the technical field of steel pipe detection, and in particular to fully automatic operation equipment for water pressure testing of ultra-slender steel pipes. Background Art

[0002] The existing steel pipe water pressure test equipment roughly includes three parts: a placement rack for placing steel pipes, a clamping mechanism for preventing the steel pipes from moving during the test, and a test detection mechanism symmetrically arranged on both sides of the equipment and with the inner end connected to the steel pipe. When conducting the test, the steel pipes on the placement rack are mostly moved to the clamping mechanism manually. The clamping mechanism is used to clamp and fix the steel pipes to be tested. The fixed steel pipes are tested by the detection mechanism, and finally the tested steel pipes are taken out of the detection mechanism manually.

[0003] From the above reasons, it can be seen that the existing steel pipe water pressure testing machines are mostly operated by manual assistance, and the manual operation method is relatively cumbersome and labor-intensive, which greatly increases the labor cost and labor intensity, thereby making the work efficiency of the steel pipe water pressure testing work low and unable to meet the needs of high-efficiency work; At the same time, most of the existing clamping devices clamp the steel pipe from both sides, and the bottom surface of the steel pipe will fit on the clamping mechanism. When the diameter of the steel pipe changes, the bottom surface of the steel pipe will still fit on the clamping mechanism. At this time, the axis point of the steel pipe will change compared with the previous axis point of the steel pipe. The detection mechanism located on both sides of the equipment needs to adjust its position to ensure the matching with the steel pipe. Adjusting the position will increase working time and reduce work efficiency. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Example 1 Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, comprises a fully automatic operation device for water pressure testing of ultra-slender steel pipes, comprising: The carrying unit 100 includes a workbench 101 for placing steel pipes, and two sets of detection components 102 symmetrically arranged on both sides of the workbench 101; the workbench 101 is the place where the water pressure test is carried out, and the detection component 102 is the equipment used for water pressure testing. The automation unit 200 includes a lifting component 201 vertically plugged into the workbench 101, two sets of driving wheels 202 disposed at the bottom of the workbench 101, a driving gear 203 disposed on the side of one set of driving wheels 202, and the driving gear 203 is meshed with the driving wheels 202, and a connecting gear 205 is disposed between the two sets of driving wheels 202, and the two sides of the connecting gear 205 are respectively meshed with the two sets of driving wheels 202; and, The clamping unit 300 includes a fixing component 301 located on the side of the lifting component 201, two groups of clamping components 302 symmetrically arranged on both sides of the top of the fixing component 301 in the vertical direction, an extrusion component 304 vertically inserted into the fixing component 301, the ends of the two groups of clamping components 302 respectively abut against the two sides of the extrusion component 304, and a lifting cylinder 305 vertically arranged below the extrusion component 304.

[0038] During use, the steel pipe is stored via the workbench 101, and then the automation unit 200 runs once. A steel pipe close to the clamping unit 300 is taken out through the lifting component 201 and transported to between the two groups of clamping components 302 of the clamping unit 300. The lifting cylinder 305 drives the extrusion component 304 upward, and the upward moving extrusion component 304 will synchronously push the two groups of clamping components 302 inward to clamp the steel pipe through both sides. After clamping, the two groups of detection components 102 inject high-pressure water flow into the steel pipe through both ends of the steel pipe to realize water pressure detection of the steel pipe. After the detection is completed, the extrusion component 304 moves down and no longer pushes the two groups of clamping components 302, thereby releasing the clamping of the steel pipe. At this time, the automation unit 200 moves again, and the lifting component 201 will take out the new steel pipe again through the front half, and the back half will simultaneously remove the old steel pipe from the clamping unit 300, thereby realizing automatic replacement and filling of the steel pipe, and realizing automatic operation.

[0039] Among them, there are three groups of automation units 200, and the three groups of automation units 200 include three groups of driving gears 203 and three groups of connecting gears 205. A rotating shaft is axially fixed between the three groups of driving gears 203, and one rotating end is connected to a driving motor 204. A connecting shaft is axially fixedly connected between the three groups of connecting gears 205.

[0040] During use, the driving motor 204 can drive the three sets of driving gears 203 to rotate through the rotating shaft, and the rotating driving gear 203 can drive one set of driving wheels 202 to rotate by engaging with the driving wheel 202, and the connecting gear 205 located between the two sets of driving wheels 202 is used to ensure that the two sets of driving wheels 202 can rotate synchronously and in the same direction.

[0041] Among them, the upper top surface of the workbench 101 is an inclined structure, and three groups of installation grooves 101a are evenly spaced on the workbench 101, and each group of installation grooves 101a is provided with a group of automation units 200 and a group of clamping units 300, and limiting grooves 101b are horizontally opened between the three groups of installation grooves 101a, and two groups of stop blocks 101c are fixedly arranged on both sides of each group of installation grooves 101a, and a guide block 101d is fixedly arranged on the side of the workbench 101, and the upper top surface of the guide block 101d is inclined from top to bottom.

[0042] During use, the top of the workbench 101 is tilted in such a way that the steel pipe can slide downward under the action of gravity. When the innermost steel pipe is taken away by the automation unit 200, another set of steel pipes can be filled in time. The three sets of installation grooves 101a are used to install the limit automation unit 200 and the driving gear 203, so that both can only operate under the limitation of the installation groove 101a, and the stopper 101c is used to block the steel pipe to prevent the steel pipe from accidentally falling into the limit groove 101b. A part of the installation groove 101a extends into the guide block 101d. When the object lifted by the lifting component 201 reaches the guide block 101d via the installation groove 101a, it will slide along the oblique edge of the guide block 101d and then detach from the carrying unit 100.

[0043] Among them, combined Figure 3 The detection component 102 includes a telescopic cylinder 102a fixedly arranged on both sides of the workbench 101, a head 102b arranged at the inner end of the telescopic cylinder 102a, and a connecting pipe 102c connected to the head 102b.

[0044] During use, the two telescopic cylinders 102a can drive the two heads 102b to move toward each other, thereby achieving sealing at both ends of the steel pipe. The connecting pipe 102c connected to the head 102b has a water pump connected to its outer end, which can inject high-pressure water flow into the interior of the steel pipe to achieve water pressure detection of the steel pipe.

[0045] Example 2 Reference Figure 13 to Figure 16, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the automation unit 200 can automatically replace and fill the steel pipe, thereby realizing fully automatic operation of the steel pipe water pressure test, and the lifting component 201 in the automation unit 200 can adjust the lifting range according to the diameter of the steel pipe to meet the needs of replacing and filling steel pipes of different diameters.

[0046] Compared with Example 1, further, combined with Figure 4 and Figure 5 The lifting component 201 includes a main bracket 201a located in the installation groove 101a, a triangular block 201b fixedly arranged on one side above the main bracket 201a, a left bracket 201c and a right bracket 201d symmetrically arranged on both sides of the triangular block 201b, and the lower parts of the left bracket 201c and the right bracket 201d are inserted into the main bracket 201a, a threaded rod 201e arranged in the main bracket 201a, and two groups of connecting frames 201f arranged in parallel below the main bracket 201a, and the top ends of the two groups of connecting frames 201f are fixedly connected to the bottom of the main bracket 201a.

[0047] During use, the lifting component 201 is located as a whole in the installation groove 101a, and is therefore limited by the installation groove 101a and can only change its position in the vertical direction within the installation groove 101a. The triangular block 201b is an isosceles triangle structure, and the two hypotenuses of the triangle are respectively aligned with the left bracket 201c and the right bracket 201d, and the threaded rod 201e is rotatably connected to the main bracket 201a, and a knob is provided at the end of the threaded rod 201e.

[0048] Among them, combined Figure 4 and Figure 5 The left bracket 201c includes a partition block 201c1 slidably connected to the main bracket 201a, a connecting plate 201c2 laterally arranged below the partition block 201c1, and the connecting plate 201c2 is located in the main bracket 201a, and a connecting ear 201c3 is provided at the inner end of the connecting plate 201c2, and the connecting ear 201c3 is threadedly connected to the threaded rod 201e. The left bracket 201c has the same structure as the right bracket 201d.

[0049] During use, the partition block 201c1 is a triangular structure, and the oblique side of the triangular structure is opposite to the oblique side of the triangular block 201b. The distance between the two oblique sides is the range of lifting the steel pipe. The left bracket 201c is threadedly connected to the threaded rod 201e through the connecting ear 201c3, and can move horizontally along the main bracket 201a when the threaded rod 201e rotates. The moving partition block 201c1 will change the distance between it and the triangular block 201b, thereby changing the lifting range. At the same time, the right bracket 201d is symmetrically arranged on the other side of the triangular block 201b. Therefore, when the lifting range of the left bracket 201c changes, the lifting range between the right bracket 201d and the triangular block 201b will also change. Compared with separate adjustment, the synchronous transformation method is faster and more efficient.

[0050] Among them, a limiting bolt 202a is fixedly provided near the outer edge of one side of the driving wheel 202, and the ends of the two sets of connecting frames 201f are rotatably sleeved on the limiting bolt 202a. Another side of the driving wheel 202 is rotatably connected to a fixing frame, and the top end of the fixing frame is fixedly connected to the bottom surface of the workbench 101.

[0051] During use, the driving wheel 202 can synchronously drive the connecting frame 201f to move through the limiting bolt 202a when rotating. The driving wheel 202 rotates to different amplitudes, which can drive the connecting frame 201f and the main bracket 201a at its top to reach different heights. The two groups of driving wheels 202 are connected to the two groups of connecting frames 201f under the lifting component 201 through their respective limiting bolts 202a, which can keep the connecting frame 201f in a vertical state at all times.

[0052] When the automatic filling and replacement of the steel pipe in the steel pipe water pressure test is performed by the automation unit 200 of the present equipment, in the initial state, the limit bolt 202a on the driving wheel 202 is at the bottom. At this time, the driving wheel 202 is connected to the connecting frame 201f through the limit bolt 202a, and the lifting component 201 is kept retracted below the installation groove 101a as a whole (such as Figure 8 As shown), the driving motor 204 is started, and the driving motor 204 drives the driving wheel 202 to rotate clockwise through the driving gear 203. The rotating driving wheel 202 will drive the connecting frame 201f to lift the lifting component 201 as a whole to the upper left direction. The lifting component 201 moving to the upper left will cut into the outer end of the steel pipe closest to the clamping unit 300 through the left bracket 201c. The steel pipe will continue to move upward with the lifting component 201, and slide inward along the hypotenuse of the left bracket 201c. After the driving wheel 202 rotates to 90°, the steel pipe will be completely located between the left bracket 201c and the triangular block 201b (as shown in FIG. Fig. 9As shown in FIG. 1 ), the driving wheel 202 continues to lift the lifting component 201 to move, and the movement direction of the lifting component 201 is changed to lift to the upper right. When the driving wheel 202 rotates to 180 degrees, the steel pipe between the left bracket 201c and the triangular block 201b has completely separated from the workbench 101 and is located directly above the workbench 101 (as shown in FIG. 1 ). Fig.10 As shown), the steel pipe on the upper surface of the workbench 101 will move the new steel pipe to the position of the lifted steel pipe under the action of gravity. At this time, the automation unit 200 has completed the material taking action; Then the driving wheel 202 continues to drive the lifting component 201 to rotate, and the direction of the lifting component 201 will change to descend to the lower right. In the process of the driving wheel 202 rotating from 180° to 270°, the steel pipe carried by the lifting component 201 will pass through the opening above the two groups of clamping components 302 and enter the clamping range of the clamping unit 300. When the driving wheel 202 is fully rotated 270 degrees, the steel pipe located between the left bracket 201c and the triangle block 201b will be completely located between the two groups of clamping components 302 (such as Fig.11 As shown in the figure, the driving wheel 202 continues to rotate, and the direction of the lifting component 201 will change to descend to the lower left. During the descent of the lifting component 201, the bottom surface of the steel pipe will abut against the limiting groove 101b, and will eventually be placed in the limiting groove 101b and located between the two sets of clamping components 302. At this time, the automation unit 200 has completed the loading action through the lifting component 201. After the driving wheel 202 continues to rotate 360°, the driving wheel 202 drives the lifting component 201 back to the initial state (as shown in the figure). Fig.12 As shown), wait for the next operation, and work in this reciprocating cycle to achieve the purpose of automatic feeding; When the inspected steel pipe is unloaded and removed and replaced with a new one, the driving wheel 202 also drives the lifting component 201 to move. The difference is that while the lifting component 201 moves to the upper left and lifts the new steel pipe through the left bracket 201c and the triangular block 201b, the triangular block 201b will scoop up the inspected steel pipe (hereinafter referred to as the old steel pipe) between the two sets of clamping components 302 through the other side, and as the lifting component 201 is lifted, the old steel pipe will be completely located between the triangular block 201b and the right bracket 201d (as shown in FIG. Fig.13 As shown in FIG. 2 ), the old steel pipe will follow the new steel pipe in the same motion trajectory as the driving wheel 202 continues to move 180° and 270° (as shown in FIG. 2 ). Fig.14 and 15As shown in the figure, the difference is that when the driving wheel 202 rotates from 270° to 360°, the new steel pipe will be placed in the two sets of clamping components 302, and the bottom surface of the old steel pipe will abut against the bevel of the guide block 101d, and as the lifting component 201 shrinks downward, the two sides of the old steel pipe will break away from the limit of the triangular block 201b and the right bracket 201d, and finally the old steel pipe will slide along the guide block 101d and completely leave the workbench 101 (as shown in the figure). Fig.16 As shown), at this time, the lifting component 201 has completed the action of removing the steel pipe that has been inspected and replacing it with a new steel pipe. In summary, through the mutual cooperation of the various components of the automation unit 200, the equipment has achieved the function of automatically replacing and filling steel pipes, and realized the purpose of fully automatic loading and unloading of steel pipe water pressure test. Compared with the manual loading and unloading method, the working efficiency of the equipment is greatly improved.

[0053] The remaining structures are the same as those of Example 1.

[0054] Example 3 Reference Figure 6-7 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that by adjusting the clamping range, steel pipes of different diameters can be clamped and fixed, and the steel pipe can be centered while clamping it, so that the two ends of the steel pipe can be aligned with the detection component 102, thereby shortening the working time and improving the working efficiency.

[0055] Compared with Example 2, further, in combination with Figure 7 The fixing component 301 includes a fixing box 301a located in the installation groove 101a, and one side of the fixing box 301a is fixedly connected to the inner wall of the installation groove 101a, and a makeshift groove 301b is opened inside the fixing box 301a. The device has three groups of clamping units 300, and the three groups of clamping units 300 can effectively limit the position of the steel pipe.

[0056] Among them, in combination Figure 7 The clamping component 302 includes a support frame 302a arranged in a vertical direction, and the end of the support frame 302a extends into the fixed box 301a, and the top is an arc-shaped structure bending inward, a rubber wheel 302b fixedly arranged at the top of the support frame 302a, a mounting shaft 302c arranged on both sides of the lower position of the support frame 302a, and the mounting shaft 302c extends outward to be inserted into the fixed box 301a, and an extrusion wheel 302d is arranged at the end of the support frame 302a, and the extrusion wheel 302d abuts against the side of the extrusion component 304.

[0057] During use, the clamping component 302 as a whole can rotate around the installation shaft 302c as the axis. Since the extrusion wheel 302d at the end of the clamping component 302 abuts against the extrusion component 304, the extrusion component 304 can push the clamping component 302 to move through the extrusion wheel 302d during the vertical movement. The rubber wheel 302b is made of rubber material, which can ensure stable friction when clamping the steel pipe and form a buffer to prevent the steel pipe or the clamping component 302 from being damaged.

[0058] Among them, in combination Figure 7 The extrusion component 304 includes an extrusion plate 304a located in the fixed box 301a, and the extrusion plate 304a is an inverted V structure. The extrusion wheels 302d at the ends of the two sets of clamping components 302 are respectively abutted against the two oblique sides of the inverted V structure of the extrusion plate 304a, and the top wheel 304b is arranged at the top of the extrusion plate 304a.

[0059] During use, the beveled edges on both sides of the extrusion plate 304a limit the rotation direction of the clamping component 302. When the extrusion component 304 moves upward, the clamping component 302 will receive an outward and upward thrust from the side of the extrusion plate 304a through the extrusion wheel 302d at the end, which will cause the clamping component 302 to rotate inward around the mounting shaft 302c. At the same time, the top wheel 304b and the rubber wheels 302b at the top of the two groups of clamping components 302 are on the same circle. Therefore, when the extrusion component 304 drives the two groups of clamping components 302 to move, the two groups of rubber wheels 302b and the top wheel 304b move inward synchronously, and the movement distances of the three are the same.

[0060] In summary, in combination Figure 7 When the clamping unit 300 performs the clamping limit action, the lifting cylinder 305 pushes the extrusion plate 304a upward to move vertically along the clearance groove 301b. During the movement, the bevels on both sides of the extrusion plate 304a will synchronously push the two groups of extrusion wheels 302d, so that the two groups of clamping components 302 rotate synchronously inward with the installation shaft 302c as the axis. The rubber wheels 302b at the top of the two groups of clamping components 302 and the top wheels 304b at the top of the extrusion components 304 rotate synchronously. By approaching the inside in a step-by-step manner, the clamping range among the three can be changed, thereby achieving the purpose of clamping and limiting steel pipes of different diameters. At the same time, the extrusion plate 304a moving upward will also lift the steel pipe and move upward, and the clamping force applied from three directions can keep the steel pipe in the center of the clamping range of the clamping unit 300, play a three-point centering role, and perform centering operation on the steel pipe, thereby facilitating the alignment operation between the two ends of the steel pipe and the detection component 102, shortening the working time and improving the work efficiency.

[0061] The remaining structure is the same as that of Example 2.
