Description

Technical Field

[0001] The utility model belongs to the technical field of coal quality detection, in particular to a taking and placing rack for a cylindrical ceramic crucible used for coal quality testing. Background Art

[0002] In the production of coal quality research or chemical testing, coal samples are generally subjected to ashing tests. The coal ashing process is generally placed in a ceramic crucible for detection. The crucible styles are different, and the cylindrical ceramic crucible is used for the crucible.

[0003] In the Chinese patent with publication number CN214798306U, a cylindrical ceramic crucible placement rack for coal quality testing is mentioned, including: a crucible holding rack and a crucible placement device. The crucible holding rack includes a bottom plate and a longitudinal fixing rack. The longitudinal fixing rack is installed on the top of the bottom plate. A limiting holding rack composed of a positioning ring is provided. The crucible can be placed in the positioning ring. The crucible is connected and fixed, and arranged in rows and columns. This can save time when placing and taking out, and the gap placement ensures better heating uniformity and does not tip over and cause the sample to spill.

[0004] However, the crucible is placed in the fixing frame by the cooperation of the bottom plate and the longitudinal fixing frame. However, when the crucible is used, different degrees of testing need to be performed according to the size of the coal. Only by the cooperation of the positioning ring and the crucible can different coals be tested. At the same time, after the testing, when the crucible itself is large in size, it cannot be placed inside the fixing frame, resulting in limitations in the use of the pick-up and placement frame.

[0005] To this end, those skilled in the art have proposed a pick-and-place rack based on cylindrical ceramic crucibles for coal quality testing to solve the problems raised by the background technology. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a pick-up and placement rack for cylindrical ceramic crucibles for coal quality testing, so as to solve the problems of the crucible fixing effect and the like in the prior art.

[0007] A pick-and-place rack for cylindrical ceramic crucibles for coal quality testing includes a base, a connecting column arranged on the top of the base, a movable mechanism arranged on the side wall of the connecting column, a fixing mechanism arranged on the side wall of the movable mechanism, and a fixing rod arranged on the side wall of the connecting column.

[0008] Preferably, the fixing mechanism includes a fixing box, a spring arranged in the fixing box, an arc-shaped plate arranged on one side of the spring, a connecting seat arranged on the side wall of the movable mechanism, a groove plate arranged on the top of the connecting seat, a movable plate arranged in the connecting seat, a push rod arranged on the side wall of the movable plate, and a handle arranged on the side wall of the movable plate.

[0009] Preferably, the spring and the arc plate are provided in several groups, one end of the spring is fixedly connected to the inside of the fixed box, the side wall of the arc plate is fixedly connected to the inside of the fixed box through the spring, the side wall of the groove plate is fixedly connected to the top of the connecting seat, the movable plate is slidably connected to the inside of the connecting seat, one end of the push rod is fixedly connected to the side wall of the movable plate, and the handle is fixedly connected to the side wall of the movable plate.

[0010] Preferably, the movable mechanism includes a rotating plate, a sliding groove provided on a side wall of the rotating plate, a sliding block provided in the rotating plate, an arc frame provided at the bottom of the sliding block, and a roller provided on a side wall of the arc frame.

[0011] Preferably, the sliders are provided in two groups, the two groups of sliders are slidably connected inside the rotating plate, the arc frame and the rollers are provided in several groups, one end of the arc frame is rotatably connected to the side wall of the slider, and the side wall of the roller is rotatably connected to the side wall of the arc frame.

[0012] Preferably, the side wall of the fixing box is rotatably connected to the side wall of the sliding block, the side wall of the connecting seat is rotatably connected to the side wall of the rotating plate, and one end of the fixing rod is embedded in the interior of the connecting column.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model utilizes the rotating connection between the connecting seat and the rotating plate. When the crucible itself is relatively long, the handle is pulled to drive the movable plate to move out of the interior of the connecting seat, so that the overall range in the connecting seat is increased, so that the bottom of the crucible is embedded into the interior of the connecting seat through the groove plate. When the crucible is relatively large, the fixing box is pulled and the crucible is pushed so that the bottom of the crucible contacts the side wall of the arc plate. The fixed connection between the arc plate and the spring is utilized to make the arc plate push the spring to achieve a compression effect. The reverse action force of the spring is utilized to make the spring push the arc plate to fix the crucible, thereby achieving a fixing effect on the crucible and preventing the crucible from detaching.

[0015] 2. The utility model utilizes the sliding connection between the slider and the slide groove to enable the slider to move inside the slide groove. Through the rotational connection between the arc frame and the slider, the slider drives the arc frame to move synchronously when moving. Through the rotational connection between the arc frame and the roller, the arc frame moves under the action of the roller. When the arc frame moves to one side of the rotating plate, the roller moves out of the slide groove, so that the roller and the arc frame form a supporting effect on the fixed box. At the same time, when the fixed box moves out of one side of the rotating plate, the bottom of the fixed box will contact the side wall of the rotating plate, so that the fixed box is slightly inclined, thereby ensuring the fixing effect of the crucible.

[0030] Furthermore, the slider 403 is provided in two groups, and the two groups of the sliders 403 are slidably connected to the inside of the rotating plate 401. The arc frame 404 and the roller 405 are provided in several groups, one end of the arc frame 404 is rotatably connected to the side wall of the slider 403, and the side wall of the roller 405 is rotatably connected to the side wall of the arc frame 404.

[0031] Furthermore, the side wall of the fixing box 301 is rotatably connected to the side wall of the slider 403 , the side wall of the connecting seat 302 is rotatably connected to the side wall of the rotating plate 401 , and one end of the fixing rod 5 is embedded in the interior of the connecting column 2 .

[0032] As can be seen from the above, when the crucible is used up, the rotating plate 401 is rotated to make the rotating plate 401 rotate inside the connecting column 2. At the same time, the rotating plate 401 drives the connecting seat 302 to rotate synchronously, and the connecting seat 302 is kept in a vertical state as a whole by utilizing the rotating connection between the connecting seat 302 and the rotating plate 401. It is worth noting that in order to ensure the overall stability of the connecting seat 302, a load block is provided at the bottom of the connecting seat 302. When the rotating plate 401 rotates, the connecting seat 302 is always in a stable state. When the crucible itself is long, the handle 308 is pulled to make the handle 308 drive the movable plate 307 to move out of the connecting seat 302, so that the overall range of the connecting seat 302 is increased, so that the bottom of the crucible is embedded into the connecting seat 302 through the groove plate 303.

The arc frame 404 is connected to the roller 405 by rotation, and the arc frame 404 moves under the action of the roller 405. When the arc frame 404 moves to the side of the rotating plate 401, the roller 405 moves out of the slide groove 402, so that the roller 405 and the arc frame 404 form a supporting effect on the fixed box 301, and the fixed box 301 moves out of the rotating plate 401. 01 side, the bottom of the fixed box 301 will contact the side wall of the rotating plate 401, making the fixed box 301 slightly inclined, and the crucible is pushed so that the bottom of the crucible contacts the side wall of the arc plate 305, and the fixed connection between the arc plate 305 and the spring 306 is utilized to make the arc plate 305 push the spring 306 to achieve a compression effect, and the reverse action force of the spring 306 is utilized to make the spring 306 push the arc plate 305 to fix the crucible, thereby achieving a fixing effect on the crucible and preventing the crucible from detaching.

[0033] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the side wall of the fixed box 301 is rotatably connected to the side wall of the slider 403, the side wall of the connecting seat 302 is rotatably connected to the side wall of the rotating plate 401, and one end of the fixing rod 5 is embedded in the interior of the connecting column 2.

[0034] As can be seen from the above, when the rotating plate 401 rotates, the rotating plate 401 drives the fixed box 301 and the connecting seat 302 to rotate synchronously. At the same time, the rotation between the fixed box 301 and the rotating plate 401 makes the fixed box 301 and the rotating plate 401 in a vertical state.
