[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Combination Figures 1-6 A pipeline pressure testing fixture with rapid positioning includes a test bench 1, a support seat 2 for supporting the pipeline on the test bench 1, a bracket 3 fixedly installed at one end of the test bench 1, a controller 4 fixedly installed on the bracket 3, a display screen 5 and control buttons 6 installed on the controller 4, an alarm 7 installed on the controller 4, the controller 4 and the alarm 7 are connected by a signal, and a positioning mechanism 8 is installed on the test bench 1.

[0028] See Figures 2-4Furthermore, the positioning mechanism 8 includes two slides 801 opened on the test bench 1. A threaded screw 804 is rotatably installed within each slide 801. The two threaded screws 804 are meshed and driven by a gear transmission assembly 805. A movable block 808 is threadedly connected to each threaded screw 804 and slidably connected to the slide 801. A fixed plate 810 is fixedly installed on the movable block 808. A positioning clamp 811 is installed on the fixed plate 810. A disassembly assembly 816 is provided between the fixed plate 810 and the positioning clamp 811. A fixed frame 807 is fixedly installed at one end of the test bench 1. The fixed frame 807 is connected by... A motor 806 is bolted on and electrically connected to a controller 4. The output shaft of the motor 806 rotates through the test bench 1 and is fixedly connected to one end of one of the threaded screws 804. The two threaded screws 804 are set in the same thread direction. Limit blocks 809 are fixedly set at both ends of the moving block 808. Limit grooves 802 are opened in the slide groove 801. Limit blocks 809 and limit grooves 802 are slidably connected. A connecting rod 814 is fixedly set at the bottom of the fixed plate 810. A roller 815 is rotatably set on the connecting rod 814. A track 803 is opened on the test bench 1 and is rotatably connected to the roller 815.

[0029] Specifically, by starting the motor 806, the gear transmission assembly 805 meshes and drives the two screw rods 804 with the same thread direction to rotate relative to each other. This allows the two sets of moving blocks 808, which are threadedly connected to the two screw rods 804, to slide towards each other along the two slide grooves 801 under the limiting action of the limiting block 809. The moving blocks 808 drive the positioning clamps 811 to move through the fixing plate 810, so that each set of two corresponding positioning clamps 811 can clamp and position the corresponding pipe. This allows the device to perform uniform pressure tests on pipes of different diameters and from the same batch, reducing workload and improving work efficiency.

[0030] See Figures 4-6Furthermore, the disassembly and assembly assembly 816 includes a mounting plate 8161 disposed on one side of the positioning clamp 811. A fitting block 8162 is fixedly disposed on the mounting plate 8161. A slot 8163 is formed on the fitting block 8162. Slots 8164 communicating with the slot 8163 are formed on both sides of the fitting block 8162. A fitting groove 8165 that engages with the fitting block 8162 is formed on the side of the fixing plate 810 near the positioning clamp 811. An insert block 8166 that inserts into the slot 8163 is fixedly disposed within the fitting groove 8165. A telescopic cavity 8167 is formed within the insert block 8166. Two sliders 8168 are slidably disposed relative to each other within the telescopic cavity 8167. A spring 81 is fixedly disposed between the two sliders 8168. 610, a locking block 8169 is fixedly installed on the side of the slider 8168 away from the spring 81610, which engages with the slot 8164. A rotating rod 81611 is rotatably installed in the telescopic cavity 8167. A winding wheel 81612 is fixedly sleeved on the rotating rod 81611. A connecting rope 81613, which is fixedly connected to the two sliders 8168, is wound on the winding wheel 81612. An anti-slip pad 812 is glued to the side of the positioning clamp 811 away from the mounting plate 8161. A pressure sensor 813 is installed between the positioning clamp 811 and the mounting plate 8161. One end of the rotating rod 81611 rotatably passes through the telescopic cavity 8167 and is fixedly connected to a hand-tightening block 81614. The pressure sensor 813 is signal-connected to the controller 4.

[0031] Specifically, by rotating the corresponding hand-tightening block 81614, the rotating rod 81611 drives the winding wheel 81612 to rotate. When the winding wheel 81612 rotates, it can wind up the connecting rope 81613, so that the slider 8168 connected to the connecting rope 81613 is pulled by the tension, causing the locking block 8169 to disengage from the locking groove 8164 and retract into the telescopic cavity 8167. Then, the inserting block 8162 is pulled out from the inserting groove 8165, so that the positioning clamping block 811 can be quickly disassembled, which facilitates the inspection and maintenance of the positioning clamping block 811 or the pressure sensor 813, effectively extending the service life of the device.

[0032] In actual operation, multiple pipes of the same batch to be tested are placed on the support seat 2 on the test bench 1, and the multiple pipes are passed between every two opposing positioning clamps 811. Then, the motor 806 is started, and under the meshing transmission of the gear transmission assembly 805, the two screw rods 804 with the same thread direction rotate relative to each other. This allows the two sets of moving blocks 808, which are threaded to the two screw rods 804, to slide towards each other along the two sliding grooves 801 under the limiting action of the limiting block 809. The moving blocks 808 drive the positioning clamps 811 to move through the fixing plate 810, while the rollers 815 roll and lift along the track 803. The stability of the fixed plate 810 during movement allows each set of two corresponding positioning clamps 811 to clamp and position the corresponding pipe. The positioning clamps 811 continue to apply clamping pressure to the pipe, enabling the pressure sensor 813 to detect the pressure value on the pipe and display it on the display screen 5 on the controller 4. By observing the pressure value and the deformation of the pipe, the operator can test the pipe's pressure resistance. When the clamping pressure on the pipe exceeds the set value, the alarm 7 will sound to remind the operator to make timely adjustments. The anti-slip pads 812 on the positioning clamps 811 can increase friction and prevent the pipe from shifting or slipping.

[0033] When maintenance is required on the positioning clamp 811 or pressure sensor 813, rotating the corresponding hand-tightening block 81614 causes the rotating rod 81611 to drive the winding wheel 81612 to rotate. The rotation of the winding wheel 81612 winds up the connecting rope 81613, causing the slider 8168 connected to the connecting rope 81613 to be pulled by tension, which causes the locking block 8169 to disengage from the locking groove 8164 and retract into the telescopic cavity 8167. Then, the inserting block 8162 is pulled out from the inserting groove 8165, allowing for quick disassembly of the positioning clamp 811. After the positioning clamp 811 or pressure sensor 813 is repaired, rotate the hand-tightening block 81614 again to retract the locking block 8169 and compress the spring 81610. Then, engage the fitting block 8162 with the fitting groove 8165, so that the insert block 8166 automatically inserts into the slot 8163. At this time, release the hand-tightening block 81614. Under the rebound action of the spring 81610, the locking block 8169 automatically pops out of the telescopic cavity 8167 and engages with the slot 8164, thereby locking the fitting block 8162 and completing the quick installation of the positioning clamp 811.
