Abstract

The invention discloses a lower lining with an optimized station on a hydraulic breaking hammer. The lower lining comprises a lower lining body. A through hole of a drill rod is formed in the lower lining body. An annular notch is formed in the inner wall of the through hole of the lower end of the lower lining body. The notch penetrates the lower end face of the lower lining. Pin holes penetrating the outer side wall of the lower lining body are formed in the two opposite inner side walls of the notch. The lower side of the lower lining body is provided with a guide sleeve. Annular bosses are formed at the upper end and the lower end of the guide sleeve respectively. Annular grooves are formed in the outer walls of the bosses. The bosses at the upper end of the guide sleeve are connected and inserted in the notch of the lower lining body. Cylindrical pins are inserted and connected in pin holes of the lower lining. The straight pins are inserted and connected in annular grooves in the bosses of the upper end of the guide sleeve. The upper end of the guide sleeve abuts against the lower end face of the lower lining body. According to the lower lining with the optimized structure on the hydraulic breaking hammer, the guide sleeve is additionally arranged on the lower lining body, the length of the lower lining body is increased, and therefore the contact area between the lower lining and a steel chisel is increased, vibration of the steel chisel can be relieved, and abrasion of the steel chisel and the lower lining body is relieved.

Description

The lower lining of structure optimization on a kind of hydraulic breaking hammer
Technical field:
The present invention relates to the technical field of quartering hammer, more specifically to the lower lining of structure optimization on a kind of hydraulic breaking hammer.
Background technology:
Hydraulic breaking hammer is called for short " quartering hammer " or " destroyer ", the pressure that the power resources of hydraulic breaking hammer are excavators, loader or pumping plant provide, and it can more effective broken stone and rock in engineering construction, increases work efficiency.Quartering hammer is generally by cylinder body, piston, the compositions such as drill rod, the lower end of cylinder body is by being generally fixedly connected with lower lining, drill rod is plugged in lower lining, its lower lining as shown in Figure 1, and hit object the great vibrations that can produce when performing comminution process in building site due to drill rod, make drill rod that left and right can occur travelling, the lower port of lower lining is is easily worn and torn, heavy wear can be formed if dotted line in Fig. 1 is the enlarging a on border, and lower lining is generally fastened on cylinder body, be not easy dismounting, thus the left and right that indirectly drill rod occurs is moved about larger, then more easily there is wearing and tearing and distortion in drill rod,
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides the lower lining of structure optimization on a kind of hydraulic breaking hammer, and it has increased at lower lining establishes fairlead, extend the length of lower lining, thus increase with the contact area of drill rod, the vibration of drill rod can be reduced, reduce drill rod and lower liner wear.
Technology solution of the present invention is as follows:
The lower lining of structure optimization on a kind of hydraulic breaking hammer, comprise lower lining, the via hole of drill steel is formed in lower lining, the via hole inwall of lower lining lower end forms the grooving of annular, grooving runs through the lower surface of lower lining, two inside walls that grooving is relative form the pin-and-hole running through lower lining lateral wall, the downside of lower lining is provided with fairlead, on fairlead, lower two ends all form the boss of annular, the outer wall of boss forms cannelure, the boss of fairlead upper end is plugged in the grooving of lower lining, straight pin is plugged with in the pin-and-hole of lower lining, straight pin is plugged in the cannelure of fairlead upper end boss, the upper surface of described fairlead is resisted against on the lower surface of lower lining.
The diameter of described lower lining via hole equals the internal diameter of fairlead.
Pin-and-hole on described lower lining is circular, and to the cross section semicircular in shape of the cannelure on cover boss, the radius of pin-and-hole equals the radius of cannelure semi-circular arc.
Beneficial effect of the present invention is:
1, it has increased at lower lining and has established fairlead, extends the length of lower lining, thus increases with the contact area of drill rod, can reduce the vibration of drill rod, minimizing drill rod and lower liner wear.
2, the fairlead that it adopts conveniently is dismantled from lower lining, and is fairlead with the position that drill rod weares and teares at first, is convenient for changing after fairlead wearing and tearing.
3, two of the fairlead of its employing all can be connected with lower lining, thus when after wearing and tearing, is connected and can continues to use, improve the utilization rate of resource by one of wearing and tearing with lower lining.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of lining under existing quartering hammer;
Fig. 2 is structural representation of the present invention.
In figure: 1, lower lining; 11, via hole; 12, grooving; 121, pin-and-hole; 2, fairlead; 21, boss; 211, cannelure; 3, straight pin; A, enlarging.
Detailed description of the invention:
Embodiment: as shown in Figure 2, the lower lining of structure optimization on a kind of hydraulic breaking hammer, comprise lower lining 1, the via hole 11 of drill steel is formed in lower lining 1, via hole 11 inwall of lower lining 1 lower end forms the grooving 12 of annular, grooving 12 runs through the lower surface of lower lining 1, two inside walls that grooving 12 is relative form the pin-and-hole 121 running through lower lining 1 lateral wall, the downside of lower lining 1 is provided with fairlead 2, on fairlead 2, lower two ends all form the boss 21 of annular, the outer wall of boss 21 forms cannelure 211, the boss 21 of fairlead 2 upper end is plugged in the grooving 12 of lower lining 1, straight pin 3 is plugged with in the pin-and-hole 121 of lower lining 1, straight pin 3 is plugged in the cannelure 211 of fairlead 2 upper end boss 21, the upper surface of described fairlead 2 is resisted against on the lower surface of lower lining 1.
The diameter of described lower lining 1 via hole 11 equals the internal diameter of fairlead 2.
Pin-and-hole 121 on described lower lining 1 is circular, and to the cross section semicircular in shape of the cannelure 211 on cover 2 boss 21, the radius of pin-and-hole 121 equals the radius of cannelure 211 semi-circular arc.
Operating principle: the present invention sets up fairlead 2 for lower lining 1 on the basis of lower lining 1, thus the position of wearing and tearing is mainly on fairlead 2, and fairlead 2 is convenient from dismounting and change on lower lining 1 after wearing and tearing, and its fairlead 2 can use at two, when the wearing and tearing of fairlead 2 lower end, take off straight pin 3 and dismantle fairlead 2 and fairlead 2 is inverted installation, thus the upper end of fairlead 2 becomes lower end, the inwall of the upper end of fairlead 2 is intact, thus can continue to use; Fairlead 2 extends again the length of lower lining 1 simultaneously, thus increases with the contact area of drill rod, can reduce the vibration of drill rod, reduces left and right and moves about, reduce drill rod and lower liner wear.
