Description

Technical Field

[0001] The invention belongs to the field of mechanical technology, is specifically applied to the curing stage of cement strength testing blocks, and is a key device for batch curing of cement test blocks. Background Art

[0002] During the curing process of cement test blocks, manual data collection is usually used for the curing and temperature collection of cement test blocks. Many problems will arise when manually collecting data: (1) Since many cement test blocks from different periods of time are placed in the water tank, different test blocks correspond to different batches or stages of cement or clinker. Observing the water temperature data of the thermometer will cause errors and affect the strength of the test piece. It is calculated that the water temperature has a great influence on the strength of the test piece, resulting in untimely feedback of collected information and low efficiency; (2) When the test blocks are taken out manually, it is very easy to make corresponding errors. Therefore, manual curing causes great damage to the cement test blocks and the data collected from the cement test blocks is inaccurate; (3) If highly mechanized curing equipment or electrical curing equipment is used, the operation of the equipment is complicated. If the equipment is damaged during the curing process, it will also be dangerous to the staff. There are problems with the complexity of the equipment and safety. By manually collecting data, the optimal temperature for curing cement test blocks cannot be obtained.

[0003] For example, patent CN202020973459.0 discloses a fully automatic curing barrel for cement test blocks. The temperature and humidity of the curing box are adjusted by an electrical controller, and a temperature measuring head is arranged under the curing box to detect the water temperature in the curing box. Although the problems of detection efficiency and safety are solved, manual detection is still required, and the data cannot be recorded in time, resulting in a decrease in detection accuracy. Moreover, the structure of the device is complicated, and there are still many problems that have not been solved. Summary of the invention

[0010] As a preferred solution of the present invention, a positioning block is provided on the bottom plate, and the water tank mechanism is placed on the bottom plate through the positioning block. The positioning block can make the water tank mechanism more stable, and the positioning block has a simple structure and is more convenient to operate.

[0011] As a preferred solution of the present invention, the temperature measuring mechanism includes a temperature measuring bracket and a thermometer. The temperature measuring bracket is connected to the fifth connecting rod through the third rotating shaft, and the thermometer is connected to the temperature measuring bracket.

DETAILED DESCRIPTION

[0022] The experiment is further described below with reference to the accompanying drawings.

[0023] A curing device for cement test blocks comprises a water tank mechanism 1, a connecting rod mechanism 2, a temperature measuring mechanism 3 and a base 4 for installing the water tank mechanism 1, the connecting rod mechanism 2 and the temperature measuring mechanism 3. The water tank mechanism 1 is connected to the connecting rod mechanism 2, that is, the water tank mechanism 1 is placed on the base 4, one end of the connecting rod mechanism 2 is pressed down through the water tank mechanism 1, so that various components in the connecting rod mechanism 2 transmit movement, the connecting rod mechanism 2 is connected to the temperature measuring mechanism 3, and the movement of the connecting rod mechanism 2 drives the temperature measuring mechanism 3 to swing, so that the temperature measuring component of the temperature measuring mechanism 3 is inserted into the water tank mechanism 1 to measure the temperature, and the detected temperature is uploaded in time to improve the accuracy of the temperature measurement. The connecting rod mechanism 2 is connected to a reset spring 5 on the base 4. When the water tank mechanism 1 is taken out, the connecting rod mechanism 2 stops moving under the drive of the reset spring 5, and the temperature measuring mechanism 3 returns to its initial position. The entire device has a simple structure, and can achieve the curing and temperature measurement of the cement test block through a simple device.

[0024] The connecting rod mechanism 2 includes a first connecting rod assembly 2-1, a second connecting rod 2-2, a second connecting rod assembly 2-3, a fourth connecting rod 2-4, and a third connecting rod assembly 2-5 which are connected in sequence. The water tank mechanism 1 is connected to the first connecting rod assembly 2-1. The water tank mechanism 1 drives the first connecting rod assembly 2-1 to move. Through the movement of the first connecting rod assembly 2-1, the second connecting rod 2-2, the second connecting rod assembly 2-3, the fourth connecting rod 2-4, and the third connecting rod assembly 2-5 which are connected in sequence move successively. The third connecting rod assembly 2-5 is connected to the temperature measuring mechanism 3. Therefore, when the third connecting rod assembly 2-5 rotates, it drives the temperature measuring mechanism 3 to swing, thereby causing the temperature measuring mechanism 3 to measure the temperature of the water tank mechanism 1.

[0025] The first connecting rod assembly 2-1 includes a first connecting rod 2-1-1 and a first rotating shaft 2-1-2 for installing the first connecting rod 2-1-1. Since the first connecting rod 2-1-1 is a crank connecting rod, the crank connecting rod structure is convenient for one end to bear the water tank mechanism 1, and the other end is connected to the reset spring 5, and the middle is curved for transition. Therefore, a hollow position is set on the base 4 to facilitate the passage of the curved part of the first connecting rod 2-1-1. The water tank mechanism 1 and the second connecting rod 2-2 are located on both sides of the first connecting rod 2-1-1. The first connecting rod 2-1-1 is connected to the water tank mechanism 1 through the roller-2-1-3. When the water tank mechanism 1 falls, the roller is pushed 2-1-3 moves smoothly laterally, and the roller 2-1-3 can reduce the friction caused by the direct contact between the water tank mechanism 1 and the first connecting rod assembly 2-1. The first rotating shaft 2-1-2 fixes the first connecting rod 2-1-1 on the support frame 7 on the base 4 to prevent the first connecting rod 2-1-1 from leaving the motion track. The first connecting rod 2-1-1 is connected to the second connecting rod 2-2, and the first connecting rod 2-1-1 drives the second connecting rod 2-2 to move. A barb 10 is arranged at the end of the first connecting rod 2-1-1 to connect with the reset spring 5 on the base 4, so that the temperature measuring mechanism 3 can be rotated to the initial position and be in a horizontal state under the drive of the reset spring 5.

[0026] A second link assembly 2-3 is arranged between the freely movable second link 2-2 and the fourth link 2-4. The second link assembly 2-3 includes a third link 2-3-1 and a second shaft 2-3-2 for mounting the third link 2-3-1. The second shaft 2-3-2 is fixed in the middle of the third link 2-3-1. The third link 2-3-1 is fixed on the base 4. The third link 2-3-1 is used to limit the degrees of freedom of the second link 2-2 and the fourth link 2-4 to prevent the link mechanism 2 from moving too much, causing the temperature measuring mechanism 3 to swing too much, thereby causing damage to the maintenance device.

[0027] The third connecting rod assembly 2-5 includes a fifth connecting rod 2-5-1 and a third rotating shaft 2-5-2 for installing the fifth connecting rod 2-5-1. The fifth connecting rod 2-5-1 is located in the middle of the third rotating shaft 2-5-2. The third rotating shaft 2-5-2 is fixed on the base 4. The fifth connecting rod 2-5-1 and the temperature measuring mechanism 3 are respectively fixedly connected on both sides of the third rotating shaft 2-5-2. The temperature measuring mechanism 3 is connected to the fifth connecting rod 2-5-1 through the third rotating shaft 2-5-2. When the fifth connecting rod 2-5-1 moves, the temperature measuring mechanism 3 also swings accordingly to measure the temperature of the water tank mechanism 1.

[0028] The base 4 includes a bottom plate 6 and a support frame 7. The bottom plate 6 is located at the bottom of the device. A first limit screw 11 is provided on the bottom plate 6. The first limit screw 11 limits the first connecting rod 2-1-1 to prevent a large position deviation when the first connecting rod 2-1-1 moves, resulting in a large movement transmission deviation of the entire connecting rod mechanism 2, which causes the connecting rod mechanism 2 to self-lock. At the same time, when the temperature measuring mechanism 2 is in a reset state, the temperature measuring mechanism 3 is horizontal, which is convenient for the storage of the temperature measuring mechanism 3 on the one hand, and has a certain protective effect on the temperature measuring mechanism 3 on the other hand, thereby reducing the damage of the temperature measuring mechanism 3 caused by external objects. A second limit screw 12 and a third limit screw 13 are arranged on the support frame 7, a second limit screw 12 is arranged under the fourth connecting rod 2-4, and a third limit screw 13 is arranged under the fifth connecting rod 2-5 to fix the reset height of the temperature measuring mechanism 3 to prevent the connecting rod mechanism 2 from breaking through the bearing range of the reset spring 5 under the inertia of the idle stroke, causing overstroke and causing the connecting rod mechanism 2 to self-lock.

[0029] A positioning block 8 is provided on the bottom plate 6. The water tank mechanism 1 is inserted into the positioning space of the positioning block 8 from top to bottom by external force, so that the water tank mechanism 1 falls on the upper plane of the bottom plate 6. The positioning block 8 has a simple structure and is easy to operate. Compared with other fixed parts, it is simpler and more cost-effective. If the positioning block 8 is damaged, it is also easy to replace, which greatly reduces the cost and difficulty of equipment modification.

[0030] The temperature measuring mechanism 3 includes a temperature measuring bracket 3-1 and a thermometer 3-2. The temperature measuring bracket 3-1 is connected to the fifth rotating shaft 2-5-2 of the third connecting rod assembly 2-5. The movement transmitted by the connecting rod mechanism 2 drives the temperature measuring bracket 3-1 to swing, making the maintenance device simpler and eliminating the need for other additional forces to drive it to move. The thermometer 3-2 is connected to the temperature measuring bracket 3-1. When the temperature measuring bracket 3-1 swings, the thermometer 3-2 is inserted into the water tank mechanism 1 to detect the water tank mechanism 1. When the water tank mechanism 1 is removed from the base 4, the temperature measuring mechanism 3 returns to its initial position under the drive of the reset spring 5. The entire maintenance device is easy to operate and does not require manual intervention.

[0031] The thermometer 3-2 includes a temperature sensor 3-2-1 and a temperature measuring head 3-2-2. The temperature sensor 3-2-1 is connected to a temperature display head, and the temperature detected by the temperature sensor 3-2-1 is displayed by the temperature display head. The temperature sensor 3-2-1 is fixed on the temperature measuring bracket 3-1 through a rubber pad 9. The rubber pad 9 can reduce the vibration transmitted through the temperature measuring bracket 3-1 and protect the temperature sensor 3-2-1. The temperature sensor 3-2-1 is located above the temperature measuring head 3-2-2. The data of water temperature detection by the temperature head 3-2-2 in the water tank mechanism 1 is promptly transmitted through the temperature sensor 3-2-1 to realize the function of timely information transmission. A metal protection tube 14 is arranged outside the temperature measuring head 3-2-2 to protect the temperature measuring head 3-2-2. The temperature measuring head 3-2-2 is a component with temperature measurement function. This embodiment does not improve the structure of the temperature sensor 3-2-1 and the temperature measuring head 3-2-2. The temperature sensor 3-2-1 and the temperature measuring head 3-2-2 are both existing products on the market.

[0032] The water tank mechanism 1 detected by the temperature measuring mechanism 3 includes a curing box 1-1 and a test block fixing frame 1-2. The test block fixing frame 1-2 is fixed in the curing box 1-1. The cement test block 15 is placed on the test block fixing frame 1-2. The water tank mechanism contains a curing box 1-1. The curing box 1-1 uses oily resin and is processed into an integral shape. It can well prevent solution corrosion and is easy to clean. The test block fixing frame 1-2 is set inside the curing box 1-1, and the cement test block 15 is placed on the test block fixing frame 1-2. The cement test blocks 15 are placed vertically, and multiple cement test blocks 15 are distributed in a row. Then the liquid (water) prepared in advance is injected into the curing box 1-1. A honeycomb hollow or grid-type hollow rib plate is set at the bottom of the curing box 1-1 to support the cement test block 15, thereby increasing the contact area between the cement test block 15 and water, so that the cement test block 15 can better participate in the hydration reaction, and the detection of the cement test block 15 by the entire curing device is more accurate and the detection efficiency is high.

[0033] The water tank mechanism 1 is placed on the base by external force, and the water tank mechanism 1 presses down the first connecting rod assembly to make the connecting rod mechanism 2 move, and the temperature measuring mechanism 3 installed at the end of the connecting rod mechanism 2 swings with the movement of the connecting rod mechanism 2. When the water tank mechanism 1 descends, the connecting rod mechanism 2 drives the temperature measuring mechanism 3 to be inserted into the curing box 1-1, and the temperature measuring head 3-2-2 in the temperature measuring mechanism 3 detects the water temperature in the curing box 1-1. The detected data is uploaded and recorded through the temperature sensor 3-2-1 of the temperature measuring mechanism 3. When the cement test block 15 of the curing box 1-1 in the water tank mechanism 1 is taken out, the water tank mechanism 1 rises, and the connecting rod mechanism 2 drives the temperature measuring mechanism 3 to separate from the water tank mechanism 1 through the reset spring 5, detects the strength of the cement test block 15, and observes the influence of water temperature on the strength of the cement test block 15.

[0034] During the test, cement test blocks 15 of different batches or stages are placed in the same curing box 1-1 and fixed by the test block fixing frame 1-2, then the curing box 1-1 is placed on the base, liquid (water) is added to the curing box 1-1, the temperature is recorded by the temperature measuring mechanism 3, and a control group with different temperatures is set up, and the optimal curing water temperature of the cement test block 15 is obtained by comparing the strength test of the corresponding cement test block 15 at different temperatures.
