Description
Technical field：
The present invention relates to the technical field of quartering hammer, more specifically under structure optimization on a kind of hydraulic breaking hammer
Bushing.
Background technology：
Referred to as " quartering hammer " or " destroyer ", the power resources of hydraulic breaking hammer are excavator, loading machine to hydraulic breaking hammer
Or the pressure that pumping plant provides, it can in engineering construction can more effectively broken stone and rock, improve operating efficiency.Quartering hammer
Typically it is made up of cylinder body, piston, drill rod etc., the lower end of cylinder body is plugged on lower lining by being typically fixedly connected with lower bushing, drill rod
In set, it descends bushing as shown in figure 1, and because drill rod hits object in construction site and pole caused by meeting when performing comminution process
Big vibrations so that drill rod can occur left and right and move about, and the lower port of lower bushing is easily worn, and heavy wear can be formed such as
Dotted line is the enlarging a on border in Fig. 1, and lower bushing is typically fastened on cylinder body, it is not easy to is dismantled, so as to which indirect drill rod occurs
Left and right it is travelling bigger, then drill rod is easier that abrasion and deformation occurs,
The content of the invention：
The purpose of the present invention and is provided on a kind of hydraulic breaking hammer under structure optimization aiming at the deficiency of prior art
Bushing, it has increased in lower bushing sets guide sleeve, extends the length of lower bushing, so as to increase with the contact area of drill rod, can reduce
The vibration of drill rod, reduce drill rod and lower liner wear.
The technology solution of the present invention is as follows：
The lower bushing of structure optimization on a kind of hydraulic breaking hammer, including lower bushing, the via of drill steel is formed in lower bushing,
Formed on the via inwall of lower bushing lower end annular grooving, grooving run through lower bushing lower surface, grooving it is relative two in
Form the pin-and-hole through lower bushing lateral wall in side wall, the downside of lower bushing is provided with guide sleeve, on guide sleeve upper/lower terminal
The boss of annular is formed, forms annular groove on the outer wall of boss, the boss for being oriented to set upper side is plugged on the grooving of lower bushing
It is interior, straight pin is plugged with the pin-and-hole of lower bushing, straight pin, which is plugged on, to be oriented in the annular groove of set upper side boss, described guiding
The upper surface of set is resisted against on the lower surface of lower bushing.
The diameter of the via of the lower bushing is equal to the internal diameter of guide sleeve.
Pin-and-hole on described lower bushing is circular, the section semicircular in shape of the annular groove on the boss of guide sleeve, pin-and-hole
Radius be equal to annular groove semi-circular arc radius.
The beneficial effects of the present invention are：
1st, it has increased in lower bushing sets guide sleeve, extends the length of lower bushing, so as to increase with the contact area of drill rod, energy
The vibration of drill rod is reduced, reduces drill rod and lower liner wear.
2nd, the guide sleeve that it is used is convenient dismantles from lower bushing, and the position worn at first with drill rod is guide sleeve, is led
It is convenient for changing after being worn to set.
3rd, the two for the guide sleeve that it is used can be connected with lower bushing, so that after wearing for one, by one of abrasion
It is connected and can be continuing with lower bushing, improves the utilization rate of resource.

Embodiment：
Embodiment：As shown in Figure 2, on a kind of hydraulic breaking hammer structure optimization lower bushing, including lower bushing 1, lower bushing 1
The via 11 of drill steel is inside formed, the grooving 12 of annular is formed on the inwall of via 11 of the lower lower end of bushing 1, under grooving 12 runs through
The lower surface of bushing 1, the pin-and-hole 121 through the lower lateral wall of bushing 1, lower bushing 1 are formed on two relative madial walls of grooving 12
Downside be provided with guide sleeve 2, the boss 21 of annular is formed on the upper/lower terminal of guide sleeve 2, is formed on the outer wall of boss 21
Annular groove 211, the boss 21 of the upper end of guide sleeve 2 are plugged in the grooving 12 of lower bushing 1, are plugged with the pin-and-hole 121 of lower bushing 1
Straight pin 3, straight pin 3 are plugged in the annular groove 211 of the upper end boss 21 of guide sleeve 2, the upper surface of described guide sleeve 2 against
On the lower surface of lower bushing 1.
The diameter of the via 11 of the lower bushing 1 is equal to the internal diameter of guide sleeve 2.
Pin-and-hole 121 on described lower bushing 1 is circular, and the section of the annular groove 211 on the boss 21 of guide sleeve 2 is in half
Circle, the radius of pin-and-hole 121 are equal to the radius of the semi-circular arc of annular groove 211.
Operation principle：The present invention is is that lower bushing 1 sets up guide sleeve 2 on the basis of lower bushing 1, so as to the position of abrasion
Mainly on guide sleeve 2, and guide sleeve 2 is convenient from dismounting and change on lower bushing 1 after wearing, and its energy of guide sleeve 2 two uses,
When the abrasion of the lower end of guide sleeve 2, remove straight pin 3 and dismantle guide sleeve 2 and be directed to that set is 2 reverse mounted, so as to guide sleeve 2
Upper end is changed into lower end, and the inwall of the upper end of guide sleeve 2 is intact, so as to be continuing with；Guide sleeve 2 extends simultaneously again under
The length of bushing 1, so as to increase with the contact area of drill rod, the vibration of drill rod can be reduced, it is travelling to reduce left and right, reduce drill rod and
Lower liner wear.
