Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure testing machine technology, specifically to a testing pressure machine for aluminate binders. Background Technology
[0002] Aluminate binders refer to refractory castables formulated with aluminate cement as a binder, collectively known as aluminate cement-bonded refractory castables. Among these, aluminosilicate refractory castables are the most commonly used, such as clay-based refractory castables, high-alumina refractory castables, and corundum-based refractory castables. Due to their excellent hardness and rapid setting properties, aluminate binders are frequently used for temporary emergency repairs of roads, bridges, and other structures.
[0003] In the production, improvement, and research and development of aluminate binders, pressure testing machines powered by hydraulic cylinders are used to test the compressive strength and hardness of aluminate binders. Generally, the test block is placed in the pressure application area of the machine body, and the critical point value of the test block is determined by the continuous application of downward pressure by the hydraulic cylinder.
[0004] However, the inventors discovered that when the aluminate binder test block was subjected to pressure testing, the test block would shatter after reaching the critical point, and the flying fragments could easily injure the test personnel. In addition, since the hydraulic cylinder applied downward pressure, the pressure resistance of the left and right side walls of the test block could not be carried out simultaneously, and the test block was placed in the pressure application area mainly by its own weight, so there was also a risk of the test block shifting during the pressure test.

A C-shaped frame 14 is fixedly connected to the middle section of the front side of the body 11, and the downward pressure application block 13 passes through the inside of the C-shaped frame 14.
[0030] The material splash prevention assembly 2 includes a first wire mesh plate 21 fixed on the top left side of the base 12 and a second wire mesh plate 28 fixed on the top right side of the base 12. The front end face of the first wire mesh plate 21 is hinged to a front mesh plate 25 by two hinges 24. The front end face of the second wire mesh plate 28 is provided with a door lock 26 to lock the front mesh plate 25. Electric cylinders 22 are fixedly connected to both the left and right sides of the base 12. The electric cylinders 22 pass through the inside of the first wire mesh plate 21 and the second wire mesh plate 28 respectively. The ends of the telescopic shafts of the electric cylinders 22 are fixedly connected to push plates 29 by screws.
[0031] A U-shaped seat is fixedly connected above the front surface of the machine body 11. Fixed plates 18 are rotatably connected to the left and right side walls of the cylinder body of the hydraulic cylinder 19. The end of the fixed plate 18 away from the cylinder body of the hydraulic cylinder 19 is fixedly connected to the inner surface of the U-shaped seat by bolts. The vertical section of the L-shaped movable rod 16 is L-shaped. The L-shaped movable rod 16 has three ends: top, bottom and front. A shaft pin 17 passes through the top end of the L-shaped movable rod 16. The left and right ends of the shaft pin 17 are rotatably connected to the inner side wall of the U-shaped seat. The interior of the C-shaped frame 14 is provided with a through hole for the downward pressure weight block 13 to move up and down. The outer surface of the downward pressure weight block 13 slides in contact with the inner cavity side wall of the C-shaped frame 14. The rear section of the side of the first wire mesh plate 21 and the second wire mesh plate 28 that are close to each other is fixedly connected to the left and right side walls of the machine body 11.
[0032] The first wire mesh plate 21 and the second wire mesh plate 28 both have openings 27 through which the electric cylinder 22 passes; L-shaped support rods 23 are fixedly connected to the left and right side walls of the base 12; the bottom surface of the cylinder body of the electric cylinder 22 is fixedly connected to the top of the L-shaped support rod 23; an aluminate binder material block is placed in the middle area of the top surface of the base 12; the side surface of the push plate 29 that is close to each other is in contact with the left and right side surfaces of the aluminate binder material block; and the bottom surface of the pressing weight block 13 is in contact with the top surface of the aluminate binder material block.
[0033] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:
[0034] After unlocking the door lock 26 with the key and opening the front mesh panel 25 via the hinge 24, the solidified aluminate binder test block is placed in the center of the top surface of the base 12. The front mesh panel 25 is then closed, locking the door lock 26. The electric cylinder 22 is activated, causing the push plates 29 to move closer together until they contact both sides of the aluminate binder test block. The clamping action of the electric cylinder 22 ensures that the aluminate binder test block will not shift during testing, while the pressure applied by the electric cylinder 22 tests the critical point values on both sides of the aluminate binder test block. The aluminate binder test block is surrounded by the first wire mesh panel 21, the front mesh panel 25, and the second wire mesh panel 28, effectively preventing fragments from flying when the aluminate binder test block breaks.
[0035] The front end of the L-shaped movable rod 16 is driven to swing up and down by the telescopic shaft of the hydraulic cylinder 19, so that the L-shaped movable rod 16 rotates with the top end as the base point, and the bottom end drives the connecting rod 15 to swing, so that the pressure weight block 13 moves up and down inside the C-shaped frame 14. When the pressure weight block 13 continues to press down, it presses down the aluminate binder test block.
[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
