Abstract
The invention discloses a sealing ring pilot device for a disc brake, which has high assembly and operation efficiency. The sealing ring pilot device comprises a cylindrical pilot body, wherein a cylindrical joint body is connected below the pilot body; the pilot body is integrated with the joint body; the central line of the pilot body is coincided with that of the joint body; the diameter of the cross section of the pilot body is larger than that of the cross section of the joint body; and the outer edge of the top surface of the pilot body is provided with a chamfer angle. Due to the arrangement of the pilot device, when a piston body is arranged in an oil cylinder, the pilot device only needs arranging in a piston body hole, the oil cylinder is sleeved and the pilot device is taken out. Therefore, the assembly working efficiency of the disc brake is improved greatly.
Description
Technical field
The present invention relates to a kind of mining device, relate in particular to a kind of dish brake seal ring guide device.
Background technology
Dish brake is most important safety facilities in coal master's lifting winch, its intact situation directly affects the safety of elevator system, the most important parts of dish brake are oil cylinder and piston body, during normal operation, pressure oil enters oil cylinder by oil pipe, and the promotion piston body overcomes the butterfly spring force pushes piston body open, and piston body drives brake shoe again and leaves the cylinder limit, damper brake opens wide, the normally moving row of winch.
In the real work, the situation of oil cylinder " Y " shape seal ring inefficacy leakage of oil often occurs, the leakage of oil of " Y " shape seal ring will have a strong impact on the deceleration and stopping performance of winch, also can occur spacious phenomenon of not opening a sluice gate sometimes.When such situation occurring, need immediately " Y " shape seal ring to be changed.Because " Y " shape seal ring is embedded in the cylinder body, requiring with cooperating of piston body is interference fit, cooperates tightlyer, and the dish brake fitting process is complicated, at least two people's compounding practices of needs.After old seal ring is changed and is finished, when packing piston body into oil cylinder, piston body is difficult to be nested in " Y " seal ring, can only withstand " Y " shape seal ring lip by screwdriver, be pressed into the cylinder seal inside groove again, be easy to like this seal ring is damaged, all that has been achieved is spoiled to cause erection work, operates very inconvenient, inefficiency.
Summary of the invention
The purpose of this invention is to provide the high dish brake seal ring guide device of a kind of assembly working efficient.
For achieving the above object, the technical solution used in the present invention is:
A kind of dish brake seal ring guide device, comprise first conductor, elder generation's conductor is cylindrical, it is characterized in that: be connected with convergence body below the first conductor, convergence body also is cylindrical, elder generation's conductor and convergence body are structure as a whole, and the line of centers of first conductor and the line of centers of convergence body coincide, and the cross-sectional diameter of first conductor is greater than the cross-sectional diameter of convergence body; The end face outer of elder generation's conductor has chamfering.
The present invention has been arranged, when packing piston body into oil cylinder, only needed the present invention is placed on earlier in the piston body opening, and then the cover upper cylinder, take out the present invention at last and get final product, improved the assembly working efficient of dish brake greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a mounting structure scheme drawing of the present invention.
In the accompanying drawing:
1, chamfering 2, first conductor 3, convergence body 4, piston body 5, oil cylinder
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of dish brake seal ring guide device, as shown in Figure 1, comprise first conductor 2, elder generation's conductor 2 is cylindrical, be connected with convergence body 3 below elder generation's conductor 2, convergence body 3 also is cylindrical, and first conductor 2 is structure as a whole with convergence body 3, the line of centers of elder generation's conductor 2 and the line of centers of convergence body 3 coincide, and the cross-sectional diameter of first conductor 2 is greater than the cross-sectional diameter of convergence body 3; The end face outer of elder generation's conductor 2 has chamfering.
The step of using the present invention that dish brake is installed is: as shown in Figure 2, earlier piston body is placed on the platform, interior nose end up, then convergence body of the present invention is inserted in the piston body endoporus, after the bottom surface for the treatment of first conductor contact well with hole end surface in the piston body, the end that oil cylinder is equipped with seal ring is sleeved on the first conductor along first conductor end face down, and oil cylinder just can be in place.
The present invention adopts the 45# steel to form through machined into, comprise two parts, the cross-sectional diameter of convergence body is φ 50, convergence body stretches in the piston body endoporus during assembling, play centering and stable effect, the cross-sectional diameter of elder generation's conductor is φ 70, the end face outer of elder generation's conductor becomes chamfering through machined into, first guide face for seal ring, during use the chamfering of oil cylinder along first conductor is enclosed within on the first conductor, applying light oil cylinder down imports ring inner hole again, piston body and oil cylinder are coincide, this moment, first conductor exposed to the oil cylinder upper surface, the present invention was taken out the whole erection program of promptly having finished from the piston body endoporus, people of whole erection process need, and within three minutes, can finish, improved work efficiency greatly.
