Description
Technical Field
[0001] The utility model belongs to the technical field of bent-pipe steel-plastic conversion, in particular to a bent-pipe steel-plastic conversion pressure testing device. Background Art
[0002] The bent pipe steel-plastic conversion refers to a steel-plastic conversion joint, which itself contains a steel pipe section and a plastic pipe section. The plastic pipe section is usually a PE pipe. One end of the steel pipe section is butt-jointed with one end of the plastic pipe section to form a connecting section. The connecting section is mostly formed by clamping one end of the steel pipe section with one end of the plastic pipe section, and is sealed with a sealing ring.
[0003] The elbow-type steel-plastic conversion requires a pressure test. In the existing elbow-type steel-plastic conversion pressure test, the elbow-type steel plastic is usually placed on a workbench, and then the two ends of the elbow-type steel plastic are clamped and fixed by the pressure head on the cylinder. Since the elbow-type steel plastic is converted into a curved shape, this method is easily pushed out by the pressure during pressure testing, causing the elbow-type steel plastic to fall off, which not only affects the pressure test, but also easily causes harm to the surrounding staff. Therefore, we propose a elbow-type steel-plastic conversion pressure test device. Utility Model Content
[0004] The purpose of this utility model is to provide a bent-tube steel-plastic conversion pressure testing device, which clamps and fixes the bent-tube steel-plastic by setting a clamping component, specifically a clamping block and a positioning placement block, so as to prevent the bent-tube steel-plastic from falling off during testing, ensure that the bent-tube steel-plastic can complete the test smoothly, and avoid falling off to cause harm to surrounding staff. It solves the problem that the bent-tube steel-plastic conversion is easily pushed out by pressure during pressure testing, causing the bent-tube steel-plastic to fall off, which not only affects the pressure test but also easily causes harm to surrounding staff.
[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a pipe-bent steel-plastic conversion pressure testing device, comprising a workbench, a plurality of positioning blocks fixedly connected to the top of the workbench, a testing mechanism arranged above the positioning blocks, two testing mechanisms being symmetrically arranged, the parts contained in the two testing mechanisms being identical, and the testing mechanisms including a sealing assembly and a clamping assembly;
[0007] The clamping assembly includes a support seat, the back of the support seat is fixedly connected to the support seat, the front output end of the support seat is fixedly connected to an elliptical roller, a pressure rod is provided under the elliptical roller, and two clamping blocks are fixedly connected to the bottom of the pressure rod. By setting the clamping assembly, specifically after the bent tube type steel plastic is placed on the positioning placement block, the motor is started to drive the elliptical roller to rotate, and the protruding position of the elliptical roller presses the pressure rod downward, and the clamping block and the positioning placement block cooperate to clamp and fix the bent tube type steel plastic, which can prevent the bent tube type steel plastic from falling off during testing, ensure that the bent tube type steel plastic can complete the test smoothly, and avoid falling off to cause harm to surrounding staff.
[0008] Furthermore, there are two sealing assemblies, the top of the positioning block contacts the bent tube type steel plastic, and the two sealing assemblies are respectively distributed at both ends of the bent tube type steel plastic. The sealing assembly includes a fixed seat, a cylinder is fixedly connected to the right side of the fixed seat, and a pressure head is fixedly connected to the left output end of the cylinder. By setting the sealing assembly, specifically starting the cylinder to drive the pressure head close to the bent tube type steel plastic, the port of the bent tube type steel plastic is clamped and sealed, so that the bent tube type steel plastic can be fixed again, thereby improving the test effect.
[0009] Furthermore, an air hole is opened inside the pressure head, and an air pipe joint is fixedly connected to the top of the pressure head. The air pipe joint and the air hole are interconnected, and the bottom of the fixed seat is fixedly connected to the top of the workbench. When both ends of the bent pipe type steel plastic are sealed, the air pipe is connected through the air pipe joint for ventilation, and the bent pipe type steel plastic can be tested.
[0010] Furthermore, two limit rods are fixedly connected to the back of the pressure rod, and two limit blocks are fixedly connected to the corresponding sides of the two limit rods. The surface of the limit rod is in contact with the surface of the support seat. When the pressure rod moves, it will drive the limit rod and the limit block to slide on the support seat, which is used to play a limiting role and make the pressure rod move in a straight line.
[0011] Furthermore, the back of the pressure rod is fixedly connected to a fixing frame, a circular hole is opened inside the fixing frame, a vertical rod is slidably connected to the inner wall of the circular hole, a spring is sleeved on the outer side of the vertical rod, the bottom of the vertical rod is fixedly connected to the top of the workbench, the bottom of the support seat is fixedly connected to the top of the workbench, the bottom of the elliptical roller contacts the top of the pressure rod, and the bottom of the clamping block contacts the top of the bent tube steel plastic. When the pressure rod moves, the fixing frame will slide on the vertical rod and squeeze the spring, so that the clamping block can be clamped by the bent tube steel plastic under the action of elasticity.
[0012] Furthermore, the limit block is slidably connected to the support seat, the top of the spring is fixedly connected to the bottom of the fixing frame, and the bottom of the spring is fixedly connected to the top of the workbench. The corresponding sides of the clamping block and the positioning block are both provided with arc grooves. When the protruding position of the elliptical roller is away from the pressure rod, the fixing frame is reset upward by the elastic action of the spring, and the pressure rod follows and resets upward.
[0013] The utility model has the following beneficial effects:
[0014] 1. The utility model sets a clamping component. Specifically, after the bent tube steel plastic is placed on the positioning block, the motor is started to drive the elliptical roller to rotate. The protruding position of the elliptical roller presses the pressure rod downward, and the clamping block and the positioning block cooperate to clamp and fix the bent tube steel plastic. This can prevent the bent tube steel plastic from falling off during the test, ensure that the bent tube steel plastic can complete the test smoothly, and avoid falling off to cause harm to surrounding staff.
[0015] 2. The utility model sets a sealing component, specifically starts the cylinder to drive the pressure head close to the elbow steel plastic, clamps and seals the port of the elbow steel plastic. When both ends of the elbow steel plastic are sealed, the trachea is connected to the trachea joint for ventilation, and the elbow steel plastic can be tested. The pressure head is used to clamp and seal the two ends of the elbow steel plastic, so that the elbow steel plastic can be fixed again, thereby improving the test effect.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
