As for the structure of the locking device 105, it specifically includes two first wedge blocks 105b, two second wedge blocks 105c and an adjusting member 105 a.
The two first wedge blocks 105b are arranged at intervals in the left-right direction, the two first wedge blocks 105b are symmetrical relative to the vertical direction, and the upper surface and the lower surface of each first wedge block 105b are conical surfaces, so that the two first wedge blocks 105b form symmetrical conical surfaces in the left-right direction, and meanwhile, the two first wedge blocks 105b form symmetrical conical surfaces in the left-right direction.
The two second wedge blocks 105c are arranged at intervals in the up-down direction, the two second wedge blocks 105c are arranged on the upper side and the lower side of the first wedge block 105b, each second wedge block 105c is a conical surface on two sides in the left-right direction, the left conical surface and the right conical surface of the second wedge block 105c located on the upper side of the first wedge block 105b are respectively attached to the conical surfaces on the two first wedge blocks 105b, and the left conical surface and the right conical surface of the second wedge block 105c located on the lower side of the first wedge block 105b are respectively attached to the lower conical surfaces of the two first wedge blocks 105 b.
The adjusting member 105a is connected between the two first wedge blocks 105b for adjusting a distance of the two first wedge blocks 105b in the left-right direction. When the two first wedge-shaped blocks 105b approach to each other, the upper conical surfaces of the two first wedge-shaped blocks 105b press the left conical surface and the right conical surface of the second wedge-shaped block 105c on the upper side, so that the second wedge-shaped block 105c moves upwards, and the second wedge-shaped block 105c is tightly abutted against the plate hammer 103 and the hammer disc 102, thereby achieving the purpose of locking and fixing the plate hammer 103; when the board hammer 103 needs to be disassembled, the two first wedge blocks 105b are adjusted to be far away from each other by the adjusting piece 105a, the second wedge block 105c on the upper side of the first wedge block 105b is under the action of self weight and the reverse pressure of the board hammer 103 on the first wedge block, so that the second wedge block 105c moves downwards, no extrusion force is generated between the second wedge block 105c and the board hammer 103 and the hammer disc 102, and the board hammer 103 can freely move in the groove of the board hammer 103, so that the board hammer 103 is disassembled.
When the plate hammer 103 crushes stones through the technical scheme, the force applied to the plate hammer 103 is mainly the force along the circumferential direction of the rotating shaft 101, so that the locking of the plate hammer 103 is mainly the fixed locking of the plate hammer 103 in the front-back direction of the plate hammer 103 in the plate hammer 103 mounting groove 104, and the movement of the plate hammer 103 in the front-back direction of the plate hammer 103 in the plate hammer 103 mounting groove 104 is reduced. And because the width of the notch of the installation groove 104 of the plate hammer 103 is smaller than that of the groove bottom, the second wedge block 105c presses the plate hammer 103 more and more tightly in the process of moving upwards, so that the locking reliability is high, the plate hammer 103 hardly moves in the installation groove 104 of the plate hammer 103, and the damage of the plate hammer 103 in the process of crushing stone is reduced.
In addition, from the force direction analysis, the plate hammer 103 mainly receives the shearing force along the circumferential direction of the rotating shaft 101, the circumferential shearing force is converted into the force along the left-right direction due to the existence of the first wedge block 105b and the second wedge block 105c in the transmission process of the force, and meanwhile, the shearing force received by the plate hammer 103 is greatly reduced due to the existence of two-stage friction force, namely the friction between the plate hammer 103 and the second wedge block 105c and the friction between the second wedge block 105c and the first wedge block 105b, so that the force of the locking device 105 in the left-right direction is small, and therefore, the locking device 105 cannot be disengaged in the left-right direction.
Further, in order to increase the pressing force of the second wedge block 105c on the board hammer 103, the axis of the rotating shaft 101 is in the plane of the board hammer 103, and the plane of the first wedge block 105b and the plane of the second wedge block 105c are at an angle with the plane of the board hammer 103, so that when the second wedge block 105c moves upwards, the direction of the pressing force of the second wedge block 105c has a larger component force in the direction perpendicular to the board hammer 103, and according to f ═ Fn ∈ μ, the friction force between the second wedge block 105c and the board hammer 103 is increased, and the locking effect of the board hammer 103 is improved.
Further, on the basis of increasing the positive pressure on the board hammer 103, in order to reduce the stress of the second wedge-shaped block 105c on the board hammer 103, the surface where the second wedge-shaped block 105c abuts against the board hammer 103 is a conical surface, so that the contact area between the second wedge-shaped block 105c and the board hammer 103 is increased, the stress of the board hammer 103 is reduced, and the stress concentration and damage of the board hammer 103 are reduced.
In one embodiment, the axis of the rotating shaft 101 is in the plane of the board hammer 103, the plane of the first wedge-shaped block 105b and the plane of the second wedge-shaped block 105c are parallel to the plane of the board hammer 103, the surface of the second wedge-shaped block 105c abutting against the hammer disk 102 is a tapered surface, and the surface of the second wedge-shaped block 105c adjacent to the board hammer 103 is a plane. When the first wedge-shaped block 105b approaches each other to push the second wedge-shaped block 105c to move upwards, the tapered surface of the second wedge-shaped block 105c continuously presses the hammer disk 102 and the plate hammer 103, so that the effect of locking and fixing the plate hammer 103 is achieved.
Further, although the plate hammer 103 has a small force in the left-right direction by being subjected to the circumferential shearing force, there is a possibility of moving in the left-right direction, and in order to avoid the movement of the plate hammer 103 in the left-right direction, a stopper for stopping the locking device 105 from sliding in the axial direction of the rotary shaft 101 in the plate hammer 103 mounting groove 104 is provided on the second wedge block 105c abutting against the plate hammer 103 and the hammer disk 102.
Further, the structure of the stop piece specifically comprises a bump and a clamping groove.
The projection is provided on the surface of the second wedge block 105c in the up-down direction, which is in close contact with the plate hammer 103.
The draw-in groove sets up on the board hammer 103 along upper and lower direction, when the installation, insert the draw-in groove with the lug on the second wedge 105c of first wedge 105b upside earlier, then, adjust the distance between two first wedges 105b again, first wedge 105b is promoting the second wedge 105c to rise simultaneously, lug on the first wedge 105b slides in the draw-in groove, and simultaneously, lug and draw-in groove can reduce second wedge 105c and link first wedge 105b and slide in the left and right sides direction.
Alternatively, the positions of the projection and the slot may be interchanged, specifically, the projection is disposed on the surface of the board hammer 103, which is close to the second wedge block 105c, along the radial direction of the rotating shaft 101; or the locking groove is arranged on the surface of the second wedge block 105c, which is close to the board hammer 103, along the radial direction of the rotating shaft 101, and the installation and sliding manner of the locking groove are the same as those described above.
In one embodiment, the structure of the stopper can also be realized in the following manner. Specifically, the stoppers are two stoppers 105e disposed on the second wedge block 105c on the upper side of the first wedge block 105b, the two stoppers 105e are disposed on the left and right sides of the second wedge block 105c at left and right intervals, a limit groove is formed between the two stoppers 105e, and the hammer plate 102 is caught in the limit groove, thereby reducing the possibility of the locking device 105 sliding in the left and right direction.
Further, in order to preliminarily position and lock the installation position of the whole locking device 105 in the installation groove 104 of the plate hammer 103, the locking groove 2 is provided at the bottom of the installation groove 104 of the plate hammer 103 in the left-right direction, the second wedge-shaped block 105c located at the lower side of the first wedge-shaped block 105b is provided with the limit projection 105d, when the locking device 105 is firstly installed in the installation groove 104 of the plate hammer 103, the limit projection 105d thereon is inserted into the locking groove 2 to realize the quick positioning of the locking device 105, and meanwhile, the limit projection 105d and the locking groove 2 can also reduce the occurrence of large sliding of the locking device 105 in the circumferential direction of the rotating shaft 101.
Further, as for the structure of the adjusting member 105a, a bolt and a nut are specifically included. Through holes are formed in the two first wedge blocks 105b, bolts penetrate through the through holes in the two first wedge blocks 105b to connect the two first wedge blocks 105b, and then nuts are screwed on the bolts.
When two first wedge-shaped blocks 105b are required to be close to each other and the distance between the two first wedge-shaped blocks is reduced, the nut is screwed inwards, the two first wedge-shaped blocks 105b are close to each other due to the pretightening force between the nut and the bolt, so that the second wedge-shaped block 105c moves upwards to prop against the board hammer 103, and the board hammer 103 is locked.
When the board hammer 103 needs to be removed, the distance between the two needs to be enlarged, the nut is screwed outwards, the second wedge-shaped block 105c descends under the action of the self-weight or the reverse pressure of the board hammer 103 and the hammer disc 102 to the second wedge-shaped block, and finally the second wedge-shaped block 105c is separated from the board hammer 103, and the board hammer 103 can move freely.
