Description
Technical Field
The utility model belongs to the technical field of breaking hammers, and particularly relates to a hydraulic breaking hammer shell.
Background
A breaking hammer is a tool for breaking rocks, hardened road surfaces, and the like. The quartering hammer includes shell and core, the shell includes the curb plate of two relative settings, and the inner wall of every curb plate all is provided with the front plate, and the core setting is between two front plates, and curb plate, front plate and core are fixed connection in proper order, and hydraulic quartering hammer still includes that a plurality of wears to establish the wallboard bolt on two curb plates and two front plates, and the wallboard bolt is together fixed with the core of casing and hydraulic quartering hammer. The quartering hammer can produce violent vibrations when work, and in order to make the core of casing and hydraulic quartering hammer fix together more firm, when screwing up wallboard bolt, can screw up wallboard bolt through means such as lever afterburning.
At present, the Chinese patent network discloses a hydraulic breaking hammer (application No. 202021921238.5),
there are a plurality of wallboard retaining rings on this quartering hammer casing, this wallboard retaining ring outside is circular, and inside is interior hexagon's recess. The groove is provided with wallboard bolts and wallboard bolt gaskets. Because wallboard bolt's nut is the hexagon type, when hexagonal nut was screwed up in wallboard retaining ring hexagonal recess, owing to there is the clearance, the contact between nut and the wallboard retaining ring is six point contacts. When hydraulic pressure quartering hammer actually work, because normal collision produces the vibration, can come from six not equidirectional power on the retaining ring of casing, increased the probability of nut to the retaining ring collision, through six point contacts, it is great to conduct the pressure of casing retaining ring, leads to the casing retaining ring to produce the crackle, drops even, and the wallboard bolt will become flexible, and the core also can become flexible for the casing, has caused the hidden danger to hydraulic pressure quartering hammer's steady operation.
Disclosure of Invention
The utility model aims to solve the problems in the prior art, and provides a hydraulic breaking hammer shell, which aims to solve the technical problems that: how to reduce the collision of nut to the bolt dog, increase the life of bolt dog, improve the stability that core and casing are connected.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides a hydraulic breaking hammer casing, includes the curb plate of two relative settings, all is provided with the mounting hole of a plurality of correspondences on two curb plates, it has the wallboard bolt to run through on the mounting hole, the wallboard bolt includes nut section and screw thread section, fixedly connected with bolt dog around the mounting hole of one of them curb plate, the bolt dog can with the one side or the two-sided contact of nut section to restriction wallboard bolt rotates, the screw thread section stretches out from the mounting hole of another curb plate, and is connected with the nut.
Compared with the prior art, the inside hexagon socket head cap recess that contains of original bolt dog, because wallboard bolt's nut section is the hexagonal type, when hexagonal nut section was screwed up in bolt dog is hexagon socket head cap's recess, the contact between nut section and the bolt dog was six point contacts (as the A in figure 10 is the schematic diagram of six contact points), produce vibrations when hydraulic breaking hammer normal work and make nut section and bolt dog produce six not equidirectional power, the atress probability of bolt dog has been increased.
The bolt stop is now instead in contact with only one or both faces of the nut segment. The nut segments of the wallboard bolts and the bolt stops have only one or two contact points (e.g., fig. 11 and 12, B is a schematic view of one or two contact points). When the hydraulic breaking hammer normally works, the force transmitted to the bolt stop block through the one or two contact points only has one or two directions, the probability of stress of the bolt stop block is reduced, the pressure of the bolt stop block is reduced, the bolt stop block is not easy to crack or break and fall off, the service life of the bolt stop block is prolonged, and the connection stability of the machine core and the shell is improved.

Two relatively independent bolt dog are better fixed nut section, easy to assemble wallboard bolt. When the hydraulic breaking hammer normally works, the force transmitted to the bolt stop dog through the two contact points only has two directions, the probability of stress of the bolt stop dog is reduced, the pressure of the bolt stop dog is reduced, the bolt stop dog is not easy to crack or break and fall off, the service life of the bolt stop dog is prolonged, and the stability of connection of the machine core and the shell is improved.
Further, the mounting hole include the mounting hole of first group and the mounting hole of second group, the mounting hole of first group and the mounting hole of second group all set up along longitudinal separation, the left side and the right of each group's mounting hole all are provided with the bolt dog, two faces of nut section respectively with two bolt dog contacts, the bolt dog restriction wallboard bolt rotates.
The two relatively independent bolt stop blocks increase the fixed points of the bolt stop blocks and the side plates, and when the bolt stop blocks are subjected to force generated by vibration, the bolt stop blocks are firmer and are not easy to damage. Two relatively independent bolt dog are better fixed nut section, easy to assemble wallboard bolt. When the hydraulic breaking hammer normally works, the force transmitted to the bolt stop dog through the two contact points only has two directions, the probability of stress of the bolt stop dog is reduced, the pressure of the bolt stop dog is reduced, the bolt stop dog is not easy to crack or break and fall off, the service life of the bolt stop dog is prolonged, and the stability of connection of the machine core and the shell is improved.
Furthermore, the middle of the bolt stop block is provided with a runway-shaped through hole, the minimum aperture of the runway-shaped through hole is larger than the aperture of the mounting hole, and the plane section and the nut section of the runway-shaped through hole can be in contact with each other and limit the rotation of the wallboard bolt.
