Description

The lower lining of structure optimization on a kind of hydraulic breaking hammer

Technical field:

This utility model 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 ", and the power resources of hydraulic breaking hammer are the pressure that excavator, loader or pumping plant provide, it can in engineering construction can more effective broken stone and rock, improve work efficiency.Quartering hammer is generally by cylinder body, piston, drill rods etc. form, 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 is as shown in Figure 1, and owing to drill rod hits object the great vibrations that can produce when performing comminution process in construction site, make drill rod that left and right can be occurred travelling, the lower port of lower lining is easily worn and torn, heavy wear can form the enlarging a that dotted line in Fig. 1 is border, and lower lining is generally fastened on cylinder body, it is not easy dismounting, thus the left and right that indirectly drill rod occurs is travelling bigger, then drill rod is easier to abrasion and deformation.

Utility model content:

The purpose of this utility model is aiming at the deficiency of prior art, and the lower lining of structure optimization on a kind of hydraulic breaking hammer is provided, it has increased at lower lining and has set fairlead, extend the length of lower lining, thus increasing 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 utility model is as follows:

The lower lining of structure optimization on a kind of hydraulic breaking hammer, including lower lining, the via of drill steel is formed in lower lining, the via inwall of lower lining lower end forms the grooving of annular, grooving runs through the lower surface of lower lining, two medial 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, it is plugged with straight pin 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 is equal to the internal diameter of fairlead.

The described pin-and-hole on lower lining is circular, the cross section semicircular in shape of the cannelure on fairlead boss, and the radius of pin-and-hole is equal to the radius of cannelure semi-circular arc.

The beneficial effects of the utility model are in that:

1, it has increased at lower lining and has set fairlead, extends the length of lower lining, thus increasing 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 is convenient dismantles from lower lining, and the position worn and torn at first with drill rod is fairlead, is convenient for changing after fairlead abrasion.

3, the two of the fairlead that it adopts all can be connected with lower lining, thus after wearing and tearing when one, one of abrasion being connected can be continuing with lower lining, improves the utilization rate of resource.

Detailed description of the invention:

nullEmbodiment: as shown in Figure 2，The lower lining of structure optimization on a kind of hydraulic breaking hammer，Including lower lining 1，The via 11 of drill steel is formed in lower lining 1，Via 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 medial 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，It is plugged with straight pin 3 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 11 is equal to the internal diameter of fairlead 2.

Pin-and-hole 121 on described lower lining 1 is circular, the cross section semicircular in shape of the cannelure 211 on fairlead 2 boss 21, and the radius of pin-and-hole 121 is equal to the radius of cannelure 211 semi-circular arc.

Operation principle: this utility model is set up fairlead 2 for lower lining 1 on the basis of lower lining 1, thus the position worn and torn is mainly on fairlead 2, and it is convenient from dismounting and change on lower lining 1 after fairlead 2 abrasion, and its fairlead 2 can use at two, when the abrasion of fairlead 2 lower end, take off straight pin 3 and dismantle fairlead 2 and to be directed to set 2 reverse mounted, thus the upper end of fairlead 2 becomes lower end, the inwall of the upper end of fairlead 2 is intact, such that it is able to be continuing with；Being simultaneously directed to set 2 and extend again the length of lower lining 1, thus increasing with the contact area of drill rod, can reduce the vibration of drill rod, it is travelling to reduce left and right, minimizing drill rod and lower liner wear.
