Description

Coking coal cake tamping machine tamping hammer structure

Technical Field

The utility model relates to a coking coal technical field, more specifically say, relate to a coking coal cake tamping machine tamping hammer structure.

Background

The tamping hammer can reduce the distance between coal particles by 28-33%, so that the colloidal body of the coal material is easy to form coal particles with different properties to be distributed and infiltrated on the surface in coking, the smaller the gap between the coal particles is, the smaller the number of the colloidal body liquid phase products required for filling the gap is, namely, more colloidal body liquid products can be uniformly distributed on the surface of the coal particles, and then stronger interface combination is formed among the coal particles in the coking process, thereby improving the coke quality; in the process of knocking and hammering the carbon particles by the tamping hammer, the hammer rod of the tamping hammer is light, the hammer head is heavy, and the whole gravity center is inclined downwards, so that when the hammer rod falls down, the hammer rod can generate large vibration and can also cause complete deformation.

SUMMERY OF THE UTILITY MODEL

Problem (A)

In order to solve the technical problem, the utility model provides a coking coal cake tamping tool is with equipment of tamping hammer structure to solve the tamping hammer and strike the yielding problem of in-process hammer stem.

(II) technical scheme

In order to achieve the above object, the utility model provides a coking coal cake tamping hammer structure for tamping machine, include: hammer stem, ram rod, tup, web, exhaust hole and friction plate, the both sides fixedly connected with and the friction plate of hammer stem, and the inside fixed damping spring that is equipped with in top of hammer stem, and damping spring's inside is equipped with the buffer beam, the bottom of buffer beam sets up in ram rod, and ram rod's surface is equipped with the exhaust hole, ram rod's bottom fixedly connected with tup, and the bottom of tup is equipped with the web, be provided with elastic sealing ring between hammer stem and the ram rod.

Preferably, the buffer rod is any one of a hydraulic rod, a pneumatic rod and a spring rod.

Preferably, the surface of the friction plate is provided with a plurality of rubber hemispheres.

Preferably, the inner surface of the lower end of the hammer rod is provided with a plurality of pulleys, and the pulleys are in rolling connection with the outer surface of the stamping rod.

(III) advantageous effects

The utility model can reduce the reaction force of the tamping hammer in the using process and prolong the service life of the device; and the use of stamping rod for the vibrations that the tamping hammer produced at the rapping in-process can't directly be used the hammer stem, avoid the hammer stem to warp, and damping spring and pulley when improving work efficiency, more can absorb and offset reaction force, improve structural stability.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a bottom view of the hammer head of the present invention.

In the drawings, the corresponding relationship between the component names and the reference numbers is as follows: the device comprises a hammer rod 1, a stamping rod 2, a hammer head 3, a web plate 4, an exhaust hole 5, a friction plate 6, a pulley 7, a buffer rod 8, a damping spring 9 and an elastic sealing ring 10.

Detailed Description

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

as shown in fig. 1-2;

the embodiment provides a coking coal cake tamping hammer structure for tamping machine, includes: hammer stem 1, ram rod 2, tup 3, web 4, exhaust hole 5 and friction plate 6, the both sides fixedly connected with and the friction plate 6 of hammer stem 1, and the fixed damping spring 9 that is equipped with in 1 inside top of hammer stem, and damping spring 9's inside is equipped with buffer beam 8, buffer beam 8's bottom sets up in ram rod 2, and ram rod 2's surface is equipped with exhaust hole 5, ram rod 2's bottom fixedly connected with tup 3, and the bottom of tup 3 is equipped with web 4, be provided with elastic sealing ring 10 between hammer stem 1 and the ram rod 2.

Wherein, the buffer rod 8 is any one of a hydraulic rod, a pneumatic rod and a spring rod, which is beneficial to the stable structure and prevents the external force from being directly transmitted to the hammer rod 1 to cause the deformation thereof.

Wherein, the surface of the friction plate 6 is provided with a plurality of rubber hemispheroids, which increase the contact surface and increase the friction acting force.

Wherein, hammer stem 1 lower extreme internal surface is provided with a plurality of pulleys 7, and with the surface roll connection of punching press pole 2, can avoid the friction, also can accelerate buffer speed, improve device's sensitivity.

The working principle is as follows: as shown in fig. 1 and 2, after the hammer head 3 beats the coal particles, the produced reaction force pushes the stamping rod 2 upwards, the buffer rod 8 and the damping spring 9 are extruded and driven along the trend, the direct impact to the hammer rod 1 can be avoided, at the moment, the pulley 7 is arranged in the gap between the hammer rod 1 and the stamping rod 2, the friction between the two is reduced, the working efficiency is also improved, and the exhaust hole 5 exhausts the gas in the device, so that the pressure is reduced, and the equipment is prevented from being damaged.
