DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 and 2, a hammering device according to an embodiment of the present invention includes a ram 10, a drum hammer 20 disposed at one end of the ram 10, a cam driving mechanism 30 acting on the ram 10 and capable of lifting the ram 10, and a guiding and limiting mechanism 40.

The guide limiting mechanism 40 is matched with the tamper 10 and used for guiding and limiting the movement of the tamper 10.

Specifically, the guiding and limiting mechanism 40 of the present embodiment includes two fixing bracket plates 41 respectively disposed on two opposite sides of the tamper bar 10, wherein a baffle plate 42 is respectively fixed on an end surface of each fixing bracket plate 41 facing the tamper bar 10, and a certain gap is left between the baffle plate 42 and the tamper bar 10; two swing arms 43 are rotatably connected to the fixed support plate 41 on the side away from the tamper 10, wherein each swing arm 43 abuts against the end face of the fixed support plate 41 at the part arranged on the fixed support plate 41, and a catch wheel 44 is rotatably connected to one side of each swing arm 43 away from the fixed support plate 41; the swing arms 43 on the two fixed support plates 41 are arranged in a one-to-one correspondence manner, and elastic pieces are respectively connected between the two corresponding swing arms 43 on the two fixed support plates 41, so that the roller surfaces of the two blocking wheels 44 are attached to the tamping rod 10. That is, the guide limit mechanism 40 of the present embodiment guides and limits the tamper rod 10 by two stop wheels 44 abutting against the tamper rod 10.

Two connecting convex plates 411 are fixed on the end face of one side of the fixed support plate 41, which is far away from the baffle 42, the connecting convex plates 411 and the swing arms 43 are arranged in a one-to-one correspondence manner, and the connecting convex plates 411 and the swing arms 43 are rotatably connected through pin shafts (not shown), so that the swing arms 43 are attached to the fixed support plate 41, and the swing arms 43 are rotatably connected with the fixed support plate 41.

In the present embodiment, the swing arm 43 is provided with a rounded corner 431 at one end portion attached to the fixed bracket plate 41, and the swing arm 43 can perform a rotational movement relative to the fixed bracket plate 41 in a direction away from the corresponding fixed bracket plate 41. Because the swing arm 43 is arranged on the end surface of the fixed support plate 41 and abuts against the end surface of the fixed support plate 41, the swing arm 43 cannot rotate relative to the fixed support plate 41 in the other direction, so that when the guiding and limiting mechanism 40 of the present embodiment works, when the tamper rod 10 deflects in one direction and realizes the rotational driving of one of the blocking wheels 44, the swing arm 43 on the other blocking wheel 44 cannot rotate due to the abutting limit of the corresponding fixed support plate 41, and therefore, when the tamper rod 10 pushes the blocking wheel 44 to drive the corresponding swing arm 43 to rotate, the elastic member can be stretched, so as to realize the guiding and limiting of the tamper rod 10, and the other blocking wheel 44 is limited due to the pushing of the corresponding fixed support plate 41; thus, when the rotating catch wheel 44 loses the pushing action force of the tamper 10, the elastic member can utilize the action force generated during elastic reset to pull the rotating catch wheel 44 to reset, thereby realizing the elastic reset of the guide limiting mechanism 40.

It can be understood that, during the process of deflecting the tamper bar 10 towards one of the fixed support plates 41, the blocking wheel 44 can push the corresponding swing arm 43 to rotate relative to the fixed support plate 41, and since the fixed support plate 41 is fixed with the blocking plate 42 on the side facing the tamper bar 10, the spacing between the blocking plate 42 and the tamper bar 10 is constant. Therefore, the blocking wheel 44 which can push the tamping rod 10 to rotate drives the swing arm 43 to rotate at the maximum angle, which is the included angle between the swing arm 43 and the fixed support plate 41 when the tamping rod 10 abuts against the baffle 42.

As can be seen from the above, when the tamper bar 10 deflects and pushes one of the blocking wheels 44, the blocking wheel 44 is rotatably connected to the two corresponding swing arms 43, and the two swing arms 43 are further connected to the corresponding fixed support plate 41 in a hinged manner, so that when the tamper bar 10 acts on the blocking wheel 44, rolling friction is formed between the tamper bar 10 and the blocking wheel 44, and the frictional resistance between the two is reduced, so that the wear caused by friction when the guiding and limiting mechanism 40 operates is achieved, and the service life of the guiding and limiting mechanism 40 is further prolonged.

In this embodiment, the elastic member is a tension spring 45, one end of the tension spring 45 is fixed to the swing arm 43 of one of the fixed bracket plates 41, and the other end of the tension spring 45 is fixed to the corresponding swing arm 43 of the other fixed bracket plate 41.

Two tension springs 45 on the guide limiting mechanism 40 of the present embodiment are respectively disposed on two sides of the tamper 10, and are configured to pull two corresponding swing arms 43, so that the blocking wheels 44 disposed on two sides of the tamper 10 can respectively abut against the tamper 10. It should be noted that the two tension springs 45 are not limited to be disposed on both sides of the tamper bar 10, and those skilled in the art may also adopt a structure in which the two tension springs 45 correspondingly penetrate the tamper bar 10 according to the use requirement.

Further, the tension spring 45 is connected to the two corresponding swing arms 43 on the two fixed bracket plates 41 in a pre-tensioned manner, and by using the structural characteristics of the tension spring 45, when the tamper bar 10 pushes one of the catch wheels 44 to drive the corresponding swing arm 43 to stretch the tension spring 45, the tension spring 45 can provide greater resistance, thereby ensuring the guiding and limiting of the tamper bar 10 by the guiding and limiting mechanism 40.

In the present embodiment, the ram 10 is formed in a channel-shaped structure, and the roller surfaces of the two catch wheels 44 on the guide and limit mechanism 40 are respectively abutted against the two reinforcing rib plates 11 of the ram. Wherein the drum hammer 20 is fixedly connected with the tamper bar 10 in a welding manner. It should be noted that, in the tamper 10 of the present embodiment, a channel steel with a long length is selected, so as to improve the pushing force on the pulverized coal when the tamper 10 and the drum hammer 20 fall under the action of gravity. Wherein, the length of the tamper 10 is 15m-20 m.

In this embodiment, the cam driving mechanism 30 is disposed at a side adjacent to the drum hammer 20, wherein the cam driving mechanism 30 includes two cams 31, two of the cams 31 are respectively disposed at two opposite sides of the main plate 12 on the channel steel, and the two cams 31 can lift the main plate 10 when cooperating to rotate, so as to lift the tamper bar 10. The hammering device according to the present embodiment makes full use of the structural characteristics of the channel, and when the channel is unbalanced in force, the channel can be deflected in the direction of the guide stopper mechanism 40, but not in the direction of the cam driving mechanism 30.

The cam driving mechanism 30 of the present embodiment further includes an elastic adjustment component (not shown) for elastically adjusting the distance between the two cams 31. Make two when the cam 31 cooperation is rotated to the lifting drive of tamper 10, two interval between the cam 31 is at the in-process that constantly reduces under the elastic adjustment of elasticity adjusting part, two the cam 31 can not extrude the mainboard 12 deformation of tamper 10 to this ensures the cam actuating mechanism 30 is to the lifting drive of tamper 10. It should be noted that, the elastic adjustment assembly may be a spring according to the use requirement, and elastically adjusts the driving assemblies that respectively drive the cams 31 to rotate, so that when the driving assembly drives the cams 31 to rotate during operation, the two cams 31 do not excessively reduce the distance between the two cams when driving the tamper rod 10 to move upward, thereby preventing the main plate 12 of the tamper rod 10 from being deformed due to pressure.

In this embodiment, a certain gap is left between each cam 31 and two reinforcing rib plates 11 of the tamper 10, so that when the tamper 10 together with the drum hammer 20 pushes pulverized coal, a certain deviation of the tamper 10 does not affect the fit between the tamper 10 and the cam 31 on the cam driving mechanism 30. It should be noted that, the cam driving mechanism 30 is disposed adjacent to the drum hammer 20, and by utilizing the characteristic that the tamping rod 10 is subjected to unbalanced force to cause deviation, the deviation amount of the portion of the tamping rod 10 matched with the cam driving mechanism 30 is smaller, and the deviation amount of the portion of the tamping rod 10 away from the drum hammer 20 can be guided and limited by the guiding and limiting mechanism 40, so as to meet the use requirement of the pressure-boosting device for boosting the pulverized coal during operation.

It can be understood that, when the tamping device of the present embodiment is in operation, as the pulverized coal is continuously added, the tamper rod 10 and the tamper hammer 20 of the present embodiment are continuously lifted, so that the portion of the tamper rod 10 which is engaged with the cam 31 of the cam driving mechanism 30 is continuously moved toward the tamper hammer 20.

In conclusion, the hammering device provided by the invention has a simple structure, the ram can be lifted by the cam driving mechanism, then the ram and the drum hammer fall under the action of gravity, and the pulverized coal is beaten to be compacted, so that the hammering device is convenient to control; simultaneously this beat pressure equipment is with dividing fender wheel with rotatable mode and the cooperation of pounding rod contact of living in the tamping rod both sides to this realizes falling and using the guide spacing when pounding the buggy with the pounding drum hammer to the tamping rod, reduces the produced frictional resistance of direction stop gear when leading spacing to the tamping rod, has the effect of extension direction stop gear life.
