Problems solved by technology

In this way, the above-mentioned structure brings the following problems: 1. The concentricity requirements of the sealing fit between the piston and the cylinder body are all extremely high, and the processing cost is relatively high
2. The sealing gap between the upper and lower cavity seals is large, and the seal is squeezed out under the oil pressure, resulting in poor lubrication, resulting in a short service life of the seal and easy failure of the seal
There is a defect that the seal is easily damaged
3. Because there is no special guide, the piston and the inner cavity of the cylinder are easy to interfere, causing the cylinder to be pulled, and the piston and the cylinder to be scrapped
There is a defect that the piston is easy to be strained

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, invention is described in further detail.

[0010] Such as figure 1 As shown, a sealing and guiding structure of a breaking hammer includes a cylinder body 1, a piston 2, a lower cavity seal 3 between the cylinder body 1 and the piston 2, a nitrogen gas seal 4, and nitrogen gas 6 in the cylinder body 1. A guide ring 7 is arranged in the cavity formed by the cylinder body 1 and the piston 2 between the lower cavity seal 3 and the nitrogen gas seal 4 , and a floating seal 5 is arranged between the cylinder body 1 and the piston 2 . A guide ring 7 is added at the upper and lower ends of the cavity where the seals are installed to guide the movement of the piston 2 . In addition, the gap seal of the piston 2 is changed to a floating seal, and the floating seal can have one or several upper and lower seals. The floating seal 5 is installed on the piston 2. The outer ring surface of the floating seal 5 is attached to the inner...

Abstract

The invention discloses a sealing and guiding structure of a quartering hammer. The sealing and guiding structure of the quartering hammer comprises a cylinder body, a piston, lower cavity seals, nitrogen seals and nitrogen in the cylinder body, wherein the lower cavity seals and the nitrogen seals are arranged between the cylinder body and the piston. Guiding rings are arranged in a cavity formed by the parts, between the lower cavity seals and the nitrogen seals, of the cylinder body and the piston. Floating sealing pieces are arranged between the cylinder body and the piston. The sealing and guiding structure of the quartering hammer has the beneficial effects that structure is durable and sealing effect is good.

Description

technical field [0001] The invention belongs to the field of construction machinery equipment, and in particular relates to a sealing and guiding structure of a breaking hammer. Background technique [0002] At present, the structure of the hydraulic breaker cylinder on the market is mainly composed of the cylinder, the piston, the lower chamber seal between the cylinder and the piston, the nitrogen seal, and the nitrogen in the cylinder. Wherein, a lower chamber seal and an upper chamber seal are respectively installed at both ends of the oil cylinder, but there is no piston guide element at these two places. There are two protrusions in the middle of the piston, which cooperate with the inner cavity of the cylinder to form a piston seal and guide the movement of the piston. In this way, the above-mentioned structure brings the following problems: 1. The concentricity requirement of the sealing fit between the piston and the cylinder body is extremely high, and the process...
