Description

Technical Field

[0002] The coking tamping machine is a piece of equipment used in the coking production process, usually used to tamp and shape the coke material. In the coking process of the coke oven, the coke material needs to be evenly filled into the furnace and tamped by a tamping hammer consisting of a hammer rod and a hammer head to ensure the density and uniformity of the coke material in the furnace. During the tamping process, the operator needs to understand the movement status of each group of hammer rods in a timely manner to ensure that the hammer rods are in a normal state and to ensure the effective operation and production quality of the coking tamping machine.

[0003] The existing coking tamping machine is equipped with multiple groups of hammers and hammer heads, and the driving device drives multiple groups of hammers to move up and down simultaneously. However, if one of the groups of hammers fails, such as the movement is not smooth or stagnant, it will directly affect the tamping effect. Since the operator cannot monitor the movement status of each group of hammers in real time, this failure may not be detected for a long time. If it is not repaired in time, the abnormal movement of the group of hammers will continue to affect the tamping quality, and then affect the uniformity and density of the coke.

[0027] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] A hammer head 11 is fixedly connected to the lower surface of the hammer head 1 .

[0030] The utility model installs racks 5 on both sides of the hammer rod 1, and meshes and installs a gear 51 on one side of the rack 5, and then connects the shaft 52 inside the gear 51 with the shaft end of the encoder 7 through a connecting buckle 55. When the coking tamping machine is in operation, the driving device 2 drives the hammer rod 1 to move up and down reciprocatingly, and the hammer rod 1 indirectly drives the racks 5 on both sides to move up and down, thereby driving the gear 51 and the shaft 52 to rotate, and the encoder 7 transmits the rotation parameters of the shaft 52 to the main controller, and the operator can judge whether the movement of the hammer rod 1 is in a normal state through the rotation parameters transmitted back by the encoder 7.

[0031] Secondly, metal plates 82 are installed at the upper and lower ends of the rack 5, and proximity switches 9 are installed at the upper and lower ends of the inner wall of the box 6 that provides a sliding path for the rack 5. When the hammer rod 1 moves to the high position and the low position, two groups of proximity switches 9 will be triggered respectively. The proximity switch 9 transmits the signal to the main controller, and the operator can judge whether the hammer rod 1 is currently in the high position or the low position through the signal transmitted back by the proximity switch 9; and can also judge whether the movement of the corresponding hammer rod 1 is in a normal state by comparing the time when the proximity switch 9 corresponding to each group of hammer rods 1 generates a signal.

[0032] Further, the front and rear side walls of the movable plate 3 are connected to multiple sets of sliding members 4, and the sliding members 4 include a base 41, the base 41 is fixedly connected to the side wall of the movable plate 3, one side of the base 41 is fixedly connected to a sleeve 42, the inside of the sleeve 42 is slidably connected to a sliding rod 43, and the end of the sliding rod 43 away from the sleeve 42 is fixedly connected to a fixed seat 44, and both sides of the fixed seat 44 are rotatably connected to rollers 45 through short shafts, and the outer side of the sliding rod 43 is sleeved with a spring 46, and one end of the spring 46 abuts against On the side of the sleeve 42 away from the base 41, the other end of the spring 46 abuts against the side of the fixed seat 44 close to the slide rod 43, and the outer wall of the box body 6 close to the slide groove 62 is fixedly connected with a guide rail seat 63, which is composed of two sets of guide rails 631 installed oppositely, and the roller 45 is slidably connected inside the guide rail 631; when the hammer rod 1 drives the movable plate 3 to move up and down, the rollers 45 on both sides of the movable plate 3 slide inside the guide rail 631, making the movable plate 3 move more smoothly. At the same time, an elastic structure is adopted between the roller 45 and the base 41, so that the position between the roller 45 and the movable plate 3 is adjustable. When the movable plate 3 moves, the rollers 45 on both sides can adjust their positions according to the actual moving path of the movable plate 3. The elastic force of the spring 46 can ensure that the roller 45 always keeps in contact with the inside of the guide rail 631 during the rolling process.

[0033] Furthermore, a guide groove 632 is formed between the two sets of guide rails 631, the movable plate 3 is located inside the guide groove 632, and the width of the guide groove 632 is greater than the thickness of the movable plate 3; when the hammer rod 1 drives the movable plate 3 to slide inside the guide groove 632, since the width of the guide groove 632 is greater than the thickness of the movable plate 3, this can effectively avoid the movable plate 3 from rubbing against the guide rails 631 on both sides when sliding.

[0034] Furthermore, two groups of fixed plates 633 are symmetrically bolted on one side of the guide rail seat 63 away from the box body 6, and a plurality of groups of brushes 6331 are connected to one side of the fixed plate 633, and the brushes 6331 are blocked on the outside of the guide groove 632; the guide groove 632 is the only path for the outside to enter the box body 6, and when the coking tamping machine tamps the coal coke, the smoke and dust generated can enter the inside of the box body 6 from the guide groove 632. After the brushes 6331 are installed, the brushes 6331 can block the outside of the guide groove 632, thereby cutting off the path for the smoke and dust to enter the box body 6. At the same time, when the hammer rod 1 drives the movable plate 3 to reciprocate inside the guide groove 632, the brushes 6331 will not only not hinder the movement of the movable plate 3, but also clean the smoke and dust attached to the outside of the movable plate 3.

[0035] Furthermore, a bearing 54 is fixedly connected to the outer side of the other end of the shaft 52, and a cover plate 64 is bolted to the front side of the box 6. A through hole 641 is formed on the surface of the cover plate 64, and the bearing 54 is fixedly connected to the inside of the through hole 641. The shaft 52 forms a rotating structure with the cover plate 64 through the bearing 54; the cover plate 64 provides a position premise for the installation of the encoder 7. The shaft 52 passes through the through hole 641 and rotates through the bearing 54.

[0036] Furthermore, a fixing bracket 71 is fixedly connected to the outside of the encoder 7, and the fixing bracket 71 is bolted to the front side wall of the cover plate 64, and a protective cover 65 is bolted to the front side of the cover plate 64, and the encoder 7 is located inside the protective cover 65; the encoder 7 is firmly mounted on the front side wall of the cover plate 64 through the fixing bracket 71, providing a stable position premise for recording the rotation parameters of the shaft 52. In addition, the protective cover 65 is arranged on the outside of the encoder 7, which plays a protective role for the encoder 7.

[0037] Working principle: The driving device 2 drives the hammer rod 1 to reciprocate, and the hammer rod 1 drives the corresponding rack 5 to reciprocate up and down inside the slide 62 through the movable plates 3 on both sides. The movement of the rack 5 drives the meshing gear 51 to rotate, and then drives the shaft 52 to rotate. The shaft 52 transmits the rotational force to the shaft end of the encoder 7 through the connecting buckle 55, and the encoder 7 transmits the rotation parameters (rotation speed, rotation direction, rotation angle) of the shaft 52 to the main controller. The operator can judge whether the movement of the hammer rod 1 is in a normal state through the rotation parameters of the encoder 7 corresponding to each group of hammer rods 1 (the rotation parameters between multiple groups of hammer rods 1 under the same group of coking tamping machines can be compared / the rotation parameters of the previous group of hammer rods 1 can also be compared to judge whether the movement of the hammer rod 1 is in a normal state); at the same time, when the rack 5 reciprocates up and down, it will drive the metal plates 82 at the upper and lower ends to move. When the hammer rod 1 moves to a high position, it will indirectly drive the metal plate 82 located above to trigger the proximity switch 9 located above. When the metal plate 82 enters the sensing range of the proximity switch 9, the proximity switch 9 transmits a signal to the main controller. When the hammer rod 1 moves to a low position, it will indirectly drive the metal plate 82 located below to trigger the proximity switch 9 located below. The operator can judge whether the hammer rod 1 is in a high or low position or indirectly judge whether the movement of the hammer rod 1 is in a normal state through the signal parameters transmitted to the main controller by the proximity switch 9 (the time when multiple groups of hammer rods 1 under the same group of coking tamping machines trigger the proximity switch 9 respectively during reciprocating motion / or compare with the interval time when the group of hammer rods 1 previously triggered the upper and lower groups of proximity switches 9, so as to judge whether the movement of the hammer rod 1 is in a normal state).

[0038] Regarding the above working principle, it should be noted that: when the multiple groups of hammer rods 1 under the same group of coking tamping machines are in reciprocating motion, the rotation parameters between them will remain relatively consistent (small errors are allowed); when the multiple groups of hammer rods 1 under the same group of coking tamping machines are in reciprocating motion, the time to reach the high position and the low position is relatively consistent (specifically: the time to trigger the proximity switch 9 is relatively consistent) (small errors are allowed).

[0039] The above are only preferred implementations of the present invention and are not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
