The top end of the second telescopic rod 14 is fixed with a mounting plate 15, the mounting plate 15 is mounted towards the bearing body 6, and the driving element 16 is fixedly mounted on the mounting plate 15. In this embodiment, the driving element 16 is a motor, and the load weight 11 is driven to rotate by the motor, and the specific driving manner may be to directly detachably connect the output shaft of the motor with the connecting portion of the load weight 11 (for example, spline connection), or to drive the load weight 11 to rotate by engaging gears by providing gears that can be engaged with each other on the output shaft of the motor and the connecting portion of the load weight 11. In this embodiment, the temperature measuring element 18 is a thermocouple, and the telescopic driving member 4 is a cylinder or an oil cylinder. The lifting rotating mechanism can be arranged on the trolley and can also be separated from the trolley into independent equipment. And the lifting and falling of the lifting and falling rotating mechanism can be carried out by a telescopic cylinder and can also be manually lifted and fallen.
In the concrete implementation, when the small coke oven experiment is carried out by mixing coal, a coking coal sample 23 is put into the tank body 21, the load weight 11 is installed on the load shaft 24, and then the load shaft 24 is driven to act through the lifting equipment, so that the small coke oven experiment of mixing coal is carried out.
If a small coke oven experiment of single-variety coking coal is to be carried out, after a coking coal sample 23 is put into the tank body 21, the transfer equipment is pushed to the side of the tank body 21, and then the lifting rotating mechanism is pulled away from the trolley, so that the space above the load bearing body 6 is empty, and sufficient placing space is provided for placing the load bearing block 11. Then, the weight block 11 is lifted away from the tank body 21, the transfer device is pushed to the position under the weight block 11, the lifting polishing mechanism is driven by the telescopic driving piece 4 to be lifted to a position close to the weight block 11, then the weight block 11 is detached from the weight shaft 24, the weight block 11 falls into the bearing body 6, the cover body 17 is covered on the bearing body 6, and the connecting part of the weight block 11 extends out of the central hole 10. Then, the lifting and rotating mechanism is pushed, so that the motor as the driving element 16 drives the weight block 11 to rotate, and the weight block 11 is polished. Because coke is adhered to the weight block 11 in the small coke oven experiment process, if different coal blends are respectively subjected to the small coke oven experiment in sequence, the coke is mixed with the coal blends which are carried out later without cleaning the weight block 11, so that a coking coal sample 23 used in the experiment is impure.
The arrangement of the lower roller 2 of the connecting plate 13 is used for supporting the lifting rotating mechanism, so that the trolley is prevented from overturning.
Aiming at the small coke oven experimental device, the embodiment also provides a dual-purpose method for the small coke oven, which comprises the following steps:
the load weight 11 is detachably connected with the load shaft 24. The step enables the small coke oven to be used alternately between the small coke oven experiment of single-variety coking coal and the small coke oven experiment of coal blending.
When the experiment of the small coke oven needing to be carried out on single-variety coking coal is changed from the experiment of the small coke oven with blended coal, the transfer equipment is pushed to the side of the tank body 21, and the load bearing body 6 for loading and unloading the load weight block 11 is driven to rise through the telescopic driving piece 4, so that the load weight block 11 enters the load bearing body 6. Because the weight block 11 is heavier and the temperature of the weight block 11 which just completes the experiment of the small coke oven is higher, the bearing body 6 is lifted to facilitate the loading and the unloading of the weight block 11.
The weight 11 is then removed from the weight shaft 24 and the transfer device is pushed away from the vessel 21.
The cover body 17 is covered on the bearing body 6, the load block 11 is driven to rotate through the lifting rotating mechanism, and the teeth on the bearing body 6 and the cover body 17 polish the load block 11. This step is convenient for the coke adhered to the weight block 11 to be ground off, and the weight block 11 is cleaned while avoiding the influence thereof on the following experimental results.
Before the load block 11 enters the bearing body 6, a lifting rotating mechanism fixed on the trolley needs to be pulled away from the bearing body 6. This step is to avoid the lifting and rotating mechanism from obstructing the placement of the weight block 11.
Before the lifting and rotating mechanism drives the load weight 11 to rotate, a driving element 16 which drives the load weight 11 to rotate in the lifting and rotating mechanism is lifted. So that the driving element 16 can be abutted with the loading block 11 to drive the loading block 11 to rotate.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention.
