Description
Technical Field
[0001] This utility model relates to the field of measuring equipment technology, specifically to an adhesion index tester. Background Technology
[0002] The caking index tester is a key device specifically used to evaluate the caking properties of coal. It is mainly used in the coking, steel and coal industries. The principle of the method for determining the caking index of bituminous coal is to mix a certain mass of test coal sample and special bituminous coal under specified conditions, and then rapidly heat it into coke. The resulting coke block is then tested for strength in a drum of a certain size. The caking index is calculated using a specified formula to represent the caking level of the test coal sample.
[0003] Existing adhesion index testers, such as the Chinese utility model patent CN220154237U entitled "A Fully Automatic Adhesion Index Tester," include a housing and two rotating drums; a dual-axis motor fixedly connected to the housing, with sleeves fixedly connected to both output ends of the motor, each sleeve corresponding to a connecting groove; and a locking mechanism including a rotating rod, the connecting grooves connecting to the rotating groove, the rotating rod rotatably connected within the rotating groove, a first spring between one end of the rotating rod and the inner wall of the rotating groove, a groove on the sleeve for the other end of the rotating rod to rotate, the groove connecting to a vertical groove, a locking rod slidably connected within the vertical groove, the locking rod abutting and engaging with the rotating rod, and a second spring between the locking rod and the inner wall of the vertical groove. While this patented solution can drive the drums to rotate stably, the number of drums is only two, which is too small, resulting in low testing efficiency. Therefore, a new adhesion index tester needs to be designed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide an adhesion index tester to solve the problem mentioned in the background art that the existing devices only have two drums, which is too few and results in low detection efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adhesion index tester, comprising a base, a servo motor fixed to the outer wall of one end of the base, a horizontal threaded rod installed at the output end of the servo motor, the horizontal threaded rod being rotatably mounted on the inner side of the base via a bearing seat, the horizontal threaded rod being connected to the bottom of a movable mounting plate, a locking bolt fixed to the bottom surface of the movable mounting plate, a locking nut installed at the bottom end of the locking bolt, the locking bolt passing through a bottom track window, the bottom track window being located at the bottom of the base, the movable mounting plate passing through a top limiting window, the top limiting window being located at the top of the base, a drive motor installed on one side of the top of the movable mounting plate, a drive shaft installed at one end of the drive motor, a side limiting plate fixed to the end of the drive shaft, an installation groove provided on one side of the side limiting plate, the installation groove fitting against one end of a rotating drum, a sealing cover installed at the other end of the rotating drum, a locking post fixed to one end of the outer wall of the rotating drum, and a locking hole provided on the outer end face of the sealing cover.
[0006] Preferably, the horizontal threaded rods are symmetrically distributed about the center of the base, the helical directions of the threads on both sides of the center of the horizontal threaded rods are opposite, and movable mounting plates are symmetrically threaded at both ends of the horizontal threaded rods.
[0007] Preferably, the bottom surface of the movable mounting plate is in contact with the inner bottom surface of the base, the movable mounting plate and the top limiting window are slidably connected, and the length of the top limiting window is greater than 1 / 3 of the length of the base.
[0008] Preferably, the locking bolt and the bottom track window are slidably connected, and the length of the bottom track window is greater than 1 / 3 of the length of the base.
[0009] Preferably, the drive motor, drive shaft, and side limiting plate are symmetrically distributed about the center of the base, and the centers of the drive shaft and the side limiting plate are on the same horizontal straight line.
[0010] Preferably, the drum and the sealing cover are engaged, and locking posts are distributed at equal angles about the center of the drum on one side, and locking holes are distributed at equal angles about the center of the drum on one side of the sealing cover, with the center of the locking posts and the center of the locking holes on the same horizontal line.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the bonding index tester adopts a novel structural design, which can align and fix multiple drums through the assembly structure, and can stably fix multiple drums with the horizontal clamping mechanism, and drive multiple drums to rotate synchronously and stably through the symmetrically distributed rotation drive structure on both sides.
[0012] 1. By aligning and engaging the locking pin at the end of the drum with the locking hole at the end of the sealing cover, multiple sets of drums and sealing covers can be stably aligned and spliced, resulting in high overall stability. Combined with the side limiting plates symmetrically distributed at both ends and the pressing and fitting of the mounting groove, multiple sets of drums and sealing covers can be stably installed.
[0013] 2. A servo motor drives a horizontal threaded rod to rotate. The horizontal threaded rod uses the opposite spiral directions on both sides of its center to drive the symmetrically distributed movable mounting plates at both ends to slide towards each other along the top limit window. With the locking bolts, the plates move in a stable linear motion along the bottom track window, allowing the side limit plates to stably press and fix different numbers of drums. The horizontal threaded rod is self-locking with the movable mounting plate when it is stationary, and the locking nut presses against the bottom surface of the base, thus stabilizing the horizontal position of the movable mounting plate and the side limit plates and ensuring that the drums and sealing covers will not fall off.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4This utility model provides a technical solution: an adhesion index tester, comprising a base 1, a servo motor 2, a horizontal threaded rod 3, a movable mounting plate 4, a locking bolt 5, a locking nut 6, a bottom track window 7, a top limiting window 8, a drive motor 9, a drive shaft 10, a side limiting plate 11, a mounting groove 12, a rotating drum 13, a sealing cover 14, a locking post 15, and a locking hole 16. A servo motor 2 is fixed to the outer wall of one end of the base 1. The output end of the servo motor 2 is equipped with a horizontal threaded rod 3, which is rotatably mounted inside the base 1 via a bearing seat. The horizontal threaded rod 3 is connected to the bottom of the movable mounting plate 4, and a lock is fixed to the bottom surface of the movable mounting plate 4. A locking nut 6 is installed at the bottom of a fixing bolt 5 and a locking bolt 5. The locking bolt 5 passes through a bottom track window 7, which is located at the bottom of the base 1. A movable mounting plate 4 passes through a top limiting window 8, which is located at the top of the base 1. A drive motor 9 is installed on one side of the top of the movable mounting plate 4. A drive shaft 10 is installed at one end of the drive motor 9. A side limiting plate 11 is fixed at the end of the drive shaft 10. A mounting groove 12 is provided on one side of the side limiting plate 11. The mounting groove 12 fits against one end of the drum 13. A sealing cover 14 is installed at the other end of the drum 13. A locking post 15 is fixed at one end of the outer wall of the drum 13. A locking hole 16 is provided on the outer end face of the sealing cover 14.
[0021] In this example, the horizontal threaded rod 3 is symmetrically distributed about the center of the base 1. The helical directions of the threads on both sides of the center of the horizontal threaded rod 3 are opposite. The two ends of the horizontal threaded rod 3 are symmetrically threaded with movable mounting plates 4. The above structural design enables the horizontal threaded rod 3 to stably drive the movable mounting plates 4 symmetrically distributed at both ends to move at the same speed but in opposite directions when rotating.
[0022] The bottom surface of the movable mounting plate 4 is in contact with the inner bottom surface of the base 1. The movable mounting plate 4 and the top limiting window 8 are slidably connected. The length of the top limiting window 8 is greater than 1 / 3 of the length of the base 1. The above structural design allows the movable mounting plate 4 to slide horizontally and linearly along the top limiting window 8 under the drive of the horizontal threaded rod 3, and ensures that the range of motion of the movable mounting plate 4 is sufficient.
[0023] The locking bolt 5 is slidably connected to the bottom track window 7. The length of the bottom track window 7 is greater than 1 / 3 of the length of the base 1. The above structural design further improves the stability of the movable mounting plate 4 during sliding displacement adjustment and static use.
[0024] The drive motor 9, drive shaft 10 and side limiting plate 11 are symmetrically distributed about the center of the base 1. The centers of the drive shaft 10 and the side limiting plate 11 are on the same horizontal straight line. The above structural design enables the drive motor 9, drive shaft 10 and side limiting plate 11 to stably squeeze, position and drive the rotation of multiple sets of drums 13 and sealing covers 14 from both sides.
[0025] The drum 13 and the sealing cover 14 are connected by a snap-fit mechanism. On one side of the drum 13, there are locking pins 15 distributed at equal angles with respect to the center of the drum 13. On one side of the sealing cover 14, there are locking holes 16 distributed at equal angles with respect to the center of the drum 13. The center of the locking pins 15 and the center of the locking holes 16 are on the same horizontal straight line. The above structural design enables the drum 13 and the sealing cover 14 to be stably connected. Different sets of drums 13 and sealing covers 14 can also be stably spliced through the locking pins 15 and the locking holes 16.
[0026] Working principle: In use, first add different groups of coke blocks into different rotating drums 13, and then cover them with sealing covers 14. Then connect the different groups of rotating drums 13 and sealing covers 14 as follows: Figure 2 The positions shown are arranged so that the locking pins 15 and locking holes 16 of different groups engage and are fixed in place;
[0027] Subsequently, multiple cylindrical drums 13 and sealing caps 14 are placed between symmetrically distributed side limiting plates 11. The servo motor 2 drives the horizontal threaded rod 3 to rotate forward. The horizontal threaded rod 3, using threads with opposite helical directions on both sides of its center, drives the symmetrically distributed movable mounting plates 4, along with locking bolts 5, to slide closer to the top limiting window 8 and into the mounting grooves 12 opened on the side limiting plates 11 at both ends. Figure 2 As shown, the two ends of the multiple sets of rotating drums 13 and sealing cover 14 are tightly fitted to each other, and the multiple sets of rotating drums 13 and sealing cover 14 are horizontally squeezed and positioned. The servo motor 2 is controlled to stop working and lock the horizontal threaded rod 3. The horizontal threaded rod 3 uses the thread self-locking to fix the horizontal position of the movable mounting plate 4. The locking nut 6 is screwed on and the locking nut 6 presses the bottom surface of the base 1 to fix the horizontal position of the movable mounting plate 4 again.
[0028] Finally, the symmetrically distributed drive motors 9 can be started. The drive motors 9 drive the side limiting plates 11 and multiple sets of rotating drums 13 and sealing covers 14 to rotate rapidly through the drive shaft 10. After the rotation is completed, simply control the drive motors 9 to stop working, unscrew the locking nut 6, and control the servo motor 2 to drive the horizontal threaded rod 3 to rotate in the opposite direction. The symmetrically distributed movable mounting plates 4 and side limiting plates 11 move away from the multiple sets of rotating drums 13 and sealing covers 14 and are fixed in contact. The multiple sets of rotating drums 13 and sealing covers 14 can be removed and separated as a whole. Open the sealing cover 14 and drive the coke block inside the rotating drum 13. This is the working principle of the adhesion index tester.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
