Description

Technical Field

[0001] The invention belongs to the technical field of building component quality inspection, and in particular relates to a compression and vibration resistance testing workstation for ultra-high bonding strength concrete. Background Art

[0002] Ultra-high bond concrete is widely used in various building structures due to its high strength. However, the strength of cast components made of this material is usually affected by the formula and various environmental factors. Therefore, before the cast components are actually used, it is usually necessary to test their structural strength. Common experimental items are mostly compression and vibration resistance tests.

[0003] In existing work, the test block preparation and test phases are usually not carried out simultaneously and independently of each other. In actual work, the formula and casting scheme are often constantly revised according to the test results, which leads to errors in the test block construction and the results of the compression and vibration test due to time and environmental factors. In order to avoid this error, we concentrate the test block construction and the compression and vibration test phases in one system, so that the correlation between the test work and the test block construction work is stronger and the scheme revision is more timely and accurate, and then the compression and vibration test work is used to calculate the optimal construction conditions.

[0011] Furthermore, a feeding ramp is provided at one end of the conveying platform, and a casting pool is provided at the other end, wherein the lower edge of the feeding ramp is connected and communicated with the supporting groove, that is, when the test block is conveyed to the feeding ramp, the test block can slide into the supporting groove through the feeding ramp by its own gravity; the casting pool is located directly below the energy storage box, and the vibrating rod is located directly above the casting pool; in actual work, the energy storage box drives the turbofan to rotate by releasing the internal air pressure, and drives the vibrating rod to slide back and forth through the crankshaft connecting rod, so as to achieve the vibrating and stirring effect on the concrete slurry; the rotating shaft on the inner surface of the conveying frame is connected to the conveying shaft, and a conveying motor and a linkage shaft are arranged in the conveying platform, wherein a gear is arranged between the output shaft of the conveying motor and the linkage shaft The gear meshing structure is mechanically linked, and the opposite ends of the linkage shaft extend to the inside of the two groups of conveying frames on both sides of the conveying platform, and are mechanically linked with the conveying shaft by setting a gear meshing structure; a clamping arm is installed between the conveying frame and the conveying platform, wherein the clamping arm and the conveying frame and the conveying platform are slidably engaged by opening a mother-and-child groove; the conveying shaft is a threaded rod structure, which passes through the clamping arm and forms a reciprocating screw structure with the clamping arm by opening a threaded groove; combined with the above-mentioned technical solution, when the conveying motor is started, its output shaft drives the linkage shaft and the conveying shaft to rotate in turn through the gear meshing structure, and at the same time uses the reciprocating screw driving structure to drive the clamping arm to slide back and forth along the conveying shaft, thereby realizing the conveying of the test block;

[0012] The clamping arm is a box structure, and a clamping rod is slidably engaged on its inner surface, and a driven plate is arranged at one end of the clamping rod, which extends to the inside of the clamping arm along with the clamping rod, and is fixedly connected to the inner surface of the clamping arm by a supporting spring; a starting plate is welded and fixed to the inner surface of the clamping arm, wherein the starting plate is an electromagnet, and the driven plate is a permanent magnet, and magnetically repels the driven plate when the starting plate is energized; a support plate is welded to one side of the clamping arm, and the support plate is slidably fitted with the conveying platform; a piezoelectric switch is inlaid on the upper surface of the support plate, and the piezoelectric switch is electrically connected to the starting plate; in combination with the aforementioned technical solution, when a test block is placed above the support plate, the test block applies pressure to the piezoelectric switch, so that the starting plate is energized, and the magnetic repulsion force is used to push the clamping rod to extend outward, so as to clamp and fix the test block; and then the test block is transported to the feeding ramp in combination with the relevant conveying mechanism.

[0013] Furthermore, a feeding plate is slidably engaged with the inner surface of the casting pool, and a baffle is elastically hinged on one side of the feeding plate, wherein the outer surface of the baffle and the remaining outer surface of the feeding plate are both in contact with the inner wall of the casting pool; a lifting mechanism is also arranged inside the conveying platform, wherein the lifting mechanism includes an electric hydraulic cylinder, which is located below the casting pool, and the upper end of the output shaft of the electric hydraulic cylinder slides and extends to the inside of the casting pool and is bolted and fixed to the lower surface of the feeding plate; in combination with the specific work flow, when the casting of the test block is completed, the lifting mechanism is started, An electric hydraulic cylinder is used to push the feeding plate and the test block out of the casting pool at the same time.

In order to ensure smooth feeding, the connection between the upper end of the output shaft of the electric hydraulic cylinder and the lower end of the feeding plate can also be set to be hinged, that is, at the moment the test block is pushed out of the casting pool, the inertia of the baffle when pulling the test block causes the feeding plate to deviate, thereby further providing assistance for the feeding of the test block.

[0014] It should be added that in order to ensure the accuracy of the data of the compression and vibration test, an ultrasonic generating mechanism and an ultrasonic detector are also installed inside the workstation. The ultrasonic generating mechanism is an ultrasonic oscillator driven by a working motor.
