Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to an inorganic board strength detection device and method. Background Art

[0002] Inorganic board is a building material with non-organic substances as the main component. It is usually made of minerals, stones and other inorganic materials through high temperature and high pressure processes. This kind of board is widely used in many scenes such as building exterior walls, interior walls and roofs due to its excellent fire resistance, corrosion resistance and stability.

[0003] Inorganic boards are lighter than traditional materials such as stone and tiles, and are easy to install and efficient, so they are widely used. Inorganic boards are used as load-bearing, heat-insulating, sound-insulating or protective materials in the fields of construction, decoration, industrial equipment, etc. Their strength is directly related to the stability and safety of the structure. If the strength of the inorganic board is insufficient, the structure may deform, crack or even collapse when bearing loads, thereby threatening the safety of people and property.

[0004] At present, the characterization of the destructive strength of inorganic non-metallic plate materials is mainly carried out by destructive detection means or methods. At present, the strength of inorganic boards is tested by impact experiments. However, during the testing process, the impact is performed by the falling of a pendulum, so the impact kinetic energy range of the test is limited. The present invention provides an inorganic board strength testing device and method. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides an inorganic board strength detection device and method, which provide initial kinetic energy for the pendulum and adjust the impact kinetic energy of the pendulum during its downward swing.

[0018] A method for testing the strength of an inorganic board, characterized in that the inorganic board strength testing device described in any one of claims 1 is used, and the specific operations are as follows:

[0019] S1. First, place the inorganic board horizontally on the turning table and clamp it. Then, the turning table turns the inorganic board 90 degrees to make it contact with the pendulum, and adjusts the position of the turning table through the driving module so that the test part of the inorganic board contacts the hammer head of the pendulum.

[0020] S2, the conveying structure starts to operate, driving the pendulum to move upward to a horizontal state, and then the positioning component starts to position the pendulum, and the conveying structure returns to its original position;

[0021] S3, by rotating the striking structure, the pendulum is struck at a set speed, and the positioning assembly releases the positioning of the pendulum, so that the pendulum obtains initial kinetic energy under the strike, and starts to swing downward to obtain swinging kinetic energy, and finally hits the inorganic board, and detects the damage of the inorganic board, and the broken inorganic board falls into the collection box;

[0022] S4. Detect the initial velocity of the pendulum through the photoelectric gate sensor and calculate the kinetic energy E at the time of impact. The formula is: It is known that m is the mass of the pendulum, h is the length of the pendulum, which is also the height from the horizontal to the vertical state of the pendulum, g is the common gravitational acceleration, and v is the initial velocity obtained by the pendulum.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) By adjusting the rotation speed of the striking structure, combining the detection of the initial velocity of the pendulum by the photoelectric gate sensor and the calculation of the impact kinetic energy by the formula, the impact force and energy of the pendulum on the inorganic board can be accurately controlled to meet the detection requirements of inorganic boards of different strengths, broaden the detection range of the equipment, and provide an effective means for the detection of inorganic boards of different quality standards;

[0025] (2) The A electromagnet in the positioning assembly cooperates with the return spring to accurately control the starting position of the pendulum and release it flexibly, ensuring that the positioning and release process of the pendulum is safe and reliable and avoiding accidental injuries during operation. The design of the gear, turntable bearing and fixed column of the conveying structure can effectively drive the pendulum to a specific position. The two work together to accurately control the motion trajectory and state of the pendulum, so as to facilitate repeated testing;

[0026] (3) The electric cylinder, clamping block, air cylinder and drive module of the flip table can be used to accurately place, clamp and adjust the position of the inorganic board before testing, ensuring that the inorganic board and the hammer head of the pendulum can make precise contact, making the selection of the test point more accurate, and effectively improving the reliability and repeatability of the test results.

[0027] (4) Safety is fully considered during the design and installation of the equipment. For example, the pendulum is reliably controlled and protected through components such as electromagnets and reset springs, avoiding safety hazards caused by the pendulum to the positioning components. At the same time, components such as the flip table and the drive module adopt a sliding design, which can effectively absorb and disperse the impact force, so that the impact on the flip table is shared by the support table, while avoiding the impact on the drive module, protecting the equipment from damage.

A B electromagnet 106 is installed in the movable opening 102 of the turntable 101, and the adsorption function of the B electromagnet 106 is adjusted so that it can firmly adsorb the striking block 103 when powered on, to ensure that the striking block 103 will not be ejected during the rotation of the turntable 101. When the rotation speed of the turntable 101 reaches the set value, the B electromagnet 106 is powered off, and the striking block 103 can be smoothly ejected under the centrifugal force of the turntable 101, and accurately collide with the hammer head part of the pendulum 8, providing reliable initial kinetic energy for the pendulum 8 to swing down.

Open several groups of installation ports 133 on the positioning platform 132, install the slider 134 that can slide back and forth in the installation ports 133, and install the movable plate 135 on the slider 134, so that the movable plate 135 can slide smoothly back and forth with the positioning platform 132 through the slider 134.

[0050] A method for testing the strength of an inorganic board, the specific operation is as follows:

[0051] S1. Inorganic board placement and preparation

[0052] First, place the inorganic board to be tested horizontally on the table 122 of the flip table 12. Start the cylinder 125, and through the pushing action of the cylinder 125, the clamp 124 clamps the side of the inorganic board to ensure that the inorganic board will not be displaced during the test. Then, start the electric cylinder 123, and the electric cylinder 123 pushes the table 122 to flip around the hinge point, flipping the inorganic board 90 degrees so that it is perpendicular to the drooping pendulum 8. Finally, the flip table 12 is driven to move by the linear module 131 of the drive module 13, and the position of the flip table 12 is adjusted according to the test requirements, so that the test part of the inorganic board is in precise contact with the hammer head of the pendulum 8, preparing for the subsequent impact test.

[0053] S2. Pendulum preparation

[0054] The motor of the conveying structure 11 is started, and the motor drives the gear 112 to rotate, and the gear 112 drives the inner ring of the turntable bearing 111 to rotate, so that the fixed column 113 contacts the pendulum 8 and drives the pendulum 8 to move upward until the pendulum 8 is in a horizontal state. Next, the A electromagnet 93 of the positioning component 9 is started, and the A electromagnet 93 is energized to move forward to absorb the pendulum 8, so that the pendulum 8 is stabilized in a horizontal position. Then, the motor of the conveying structure 11 is reversed to restore the fixed column 113 to its original position to avoid interference with the subsequent movement of the pendulum 8.

[0055] S3. Pendulum striking and testing

[0056] The motor of the striking structure 10 is started, and the motor drives the turntable 101 to rotate. When the rotation speed of the turntable 101 reaches a preset value, the B electromagnet 106 is powered off, and the striking block 103 is led out under the centrifugal force of the turntable 101, and accurately collides with the hammer head part of the pendulum 8, providing initial kinetic energy for the pendulum 8 to swing down. At the same time, the A electromagnet 93 is powered off, and the pendulum 8 obtains initial kinetic energy and begins to swing down under the impact of the striking block 103, and obtains the kinetic energy of swinging under the action of gravity, and finally the pendulum 8 hits the inorganic board. After the pendulum 8 hits the inorganic board, the inspection personnel observe and detect the damage of the inorganic board, such as whether there are cracks, the degree of breakage, etc. The broken inorganic board produced by the impact will fall into the aggregate box 15, which is convenient for subsequent cleaning and analysis.

[0057] S4. Data detection and analysis

[0058] The initial velocity v obtained by the pendulum 8 is detected by the photoelectric gate sensor. The kinetic energy E at the time of impact is calculated according to the formula (where m is the mass of the pendulum 8, h is the length of the pendulum 8, which is also the height from the horizontal to the vertical state of the pendulum 8, and g is the common gravitational acceleration). In the actual detection process, the force with which the striking block 103 strikes the pendulum 8 can be changed by adjusting the rotation speed of the striking structure 10, thereby adjusting the initial velocity obtained by the pendulum 8, so that the pendulum 8 performs impact detection on the inorganic board at the set kinetic energy to meet the detection requirements of inorganic boards with different strength requirements. By testing multiple groups of inorganic boards and recording the corresponding test data, such as the initial velocity of the pendulum, the impact kinetic energy, the damage of the inorganic board, etc., the strength of the inorganic board can be comprehensively evaluated and analyzed, providing reliable data support for the quality control and application of the inorganic board.

The protection scope of the present invention is defined by the claims.

A method for testing the strength of an inorganic board, characterized in that: Using the inorganic board strength testing device described in any one of claims 1 to 6, the specific operations are as follows: S1, firstly, the inorganic board is horizontally placed on the turning table (12) and clamped, then the turning table (12) turns the inorganic board 90 degrees vertically to contact the hanging pendulum (8), and the position of the turning table (12) is adjusted by the driving module (13) so that the test part of the inorganic board contacts the hammer head of the pendulum (8); S2, the conveying structure (11) starts to operate, driving the pendulum (8) to move upward to a horizontal state, and then the positioning component (9) starts to position the pendulum (8), and the conveying structure (11) returns to its original position; S3, by rotating the striking structure (10), the striking structure (10) strikes the pendulum (8) at a set rotation speed, and at the same time the positioning assembly (9) releases the positioning of the pendulum (8), so that the pendulum (8) obtains initial kinetic energy under the strike, and starts to swing downward to obtain swinging kinetic energy, and finally strikes the inorganic board, and detects damage to the inorganic board, and the broken inorganic board falls into the collecting box (15); S4. The initial velocity of the pendulum (8) is detected by the photoelectric gate sensor, and the kinetic energy E at the time of impact is calculated. The formula is: It is known that m is the mass of the pendulum (8), h is the length of the pendulum (8), which is also the height from the horizontal to the vertical state of the pendulum (8), g is the common gravitational acceleration, and v is the initial velocity obtained by the pendulum (8). By adjusting the rotation speed of the striking structure (10), the initial velocity obtained by the pendulum (8) can be adjusted so that the pendulum (8) can be impact-tested at a set kinetic energy.
