Description

Technical Field

[0001] The invention relates to the technical field of building material detection devices, in particular to a performance detection device for building material production. Background Art

[0002] Green building materials, also known as ecological building materials, environmentally friendly building materials and healthy building materials, refer to healthy, environmentally friendly and safe building materials. They are also called "healthy building materials" or "environmentally friendly building materials" internationally. Green building materials do not refer to individual building materials products, but an evaluation of the "healthy, environmentally friendly and safe" qualities of building materials.

[0003] Announcement No. CN213632437U discloses a heat resistance detection device for the production of green building material guardrails. By setting a rotating shaft and a special clamp for the guardrail, both sides of the guardrail can be tested for heat resistance, which effectively improves the working efficiency of the heat resistance detection device for the production of green building material guardrails. By setting rollers, the heat resistance detection device for the production of green building material guardrails can be moved according to actual needs. By setting a hydraulic telescopic cylinder, the heat resistance detection device for the production of green building material guardrails is prevented from moving during use, which is more convenient to use. By setting a glass observation mirror, it is convenient for users to observe the situation of the guardrail during the temperature resistance test, which is more convenient to use. However, the patent still has the following problems in actual use:

[0004] Although the heat resistance testing device for the production of green building material guardrails allows heat resistance testing on both sides of the guardrail by setting a rotating shaft and a special guardrail clamp, thereby effectively improving the working efficiency of the heat resistance testing device for the production of green building material guardrails, it can only perform heat resistance testing on building material guardrails, and cannot perform tests on yield point, impact toughness and hardness. The test is relatively simple, and different testing instruments need to be replaced when multiple test data are needed, which is not only cumbersome to operate, but also affects the efficiency of the test.

[0005] Therefore, a performance testing device for building material production is proposed to solve the above-mentioned problems. Summary of the invention

The specific contents are as follows:

[0022] 1. By setting up a closed detection mechanism, not only can the lifting and sliding functions of the opening and closing test bench be realized by utilizing the lifting slide and translation slide inside the opening and closing bracket, but when the first connecting rope is pulled, the sliding connection block can drive the opening and closing test bench to first rise and then translate under the limiting action of the sliding limit block, thereby opening the opening and closing test bench for easy performance testing of building materials.

When the opening and closing support plate contacts the bottom of the closed detection box, under the action of the opening and closing rotating rod, the opening and closing sliding sleeve drives the reinforcement support plate to move relatively, so that the detection slot can be opened, and the bottom detection device at the bottom can be replaced with a heating device for heating, so as to facilitate the detection of the fire resistance of the building materials.

The elastic force of the clamping spring and the support spring can be used to clamp and fix the detection device, thereby improving the detection diversity of the closed detection mechanism and improving the safety of the detection by providing a closed detection environment;

[0023] 2. By setting up the opening detection mechanism, the performance of building materials can be tested under the condition of safety. The second lifting motor is started to drive the second sprocket transmission assembly and the second lifting threaded rod to rotate, so that the second lifting threaded sleeve and the second lifting sliding sleeve drive the second lifting plate to move up and down. The performance of building materials is tested by the bottom detection equipment. When the second lifting plate is lowered, the second connecting rope can be pulled to move. The characteristics of the first hook and the second hook being engaged and connected can be used to realize the movement of the second connecting rope, so that the opening and closing test bench is unfolded. When the performance of building materials is tested on the opening and closing test bench, the first hook and the second hook can be unhooked to open the bottom. When the testing equipment descends, it will not drive the opening and closing test bench to move, which is convenient for open building material performance testing.

The adjusting knob 221 drives the adjusting threaded rod 220 to rotate, so that the fixed rubber block 222 and the top detection device 223 are connected in a fit, so that the top detection device 223 can be quickly installed and replaced, thereby improving the diversity of building material performance testing.

[0043] Secondly, the lifting and sliding functions of the opening and closing test platform 109 are realized by using the lifting slide 104 and the translation slide 105 inside the opening and closing bracket 103. When the first connecting rope 113 is pulled, the sliding connection block 108 can drive the opening and closing test platform 109 to rise first and then translate under the limiting action of the sliding limit block 107, so that the opening and closing test platform 109 is opened, which is convenient for performance testing of building materials. When the compressive strength test is performed, the opening and closing test platform 109 can be opened to a certain extent, and the building materials can be placed on the top of the opening and closing test platform 109. By starting the first lifting motor 1 18 drives the first sprocket transmission assembly 119 and the first lifting threaded rod 120 to rotate, so that the first lifting threaded sleeve 121 drives the first lifting plate 122 to move up and down, and moves the reinforcement support plate 128 to the bottom of the opening and closing test bench 109, thereby processing the opening and closing test bench 109 to improve the stability of the compression test. When the fire resistance performance of the test needs to be tested, the building materials need to be heated, so a closed environment is required for testing. By placing the building materials on the top of the reinforcement support plate 128, the opening and closing test bench 109 is closed under the action of the reset spring 106.

[0044] Finally, start the first lifting motor 118 to lower the first lifting plate 122. When the opening and closing support plate 132 contacts the bottom of the closed detection box 101, under the action of the opening and closing rotating rod 131, the opening and closing sliding sleeve 127 drives the reinforcement support plate 128 to move relative to each other, so that the detection slot 125 can be opened, and the bottom detection device 140 at the bottom can be replaced with a heating device for heating, so as to facilitate the detection of the fire resistance of the building materials. By pressing the bottom detection device 140 downward, under the action of the clamping rotating rod 139, the clamping sliding sleeve 137 and the clamping arm 141 can be driven to move relative to each other, and the bottom detection device 140 can be taken out and the remaining detection devices can be replaced. The elastic force of the clamping spring 138 and the support spring 134 can be used to clamp and fix the detection equipment, thereby improving the detection diversity of the closed detection mechanism 1 and improving the safety of the detection by providing a closed detection environment.
