Description

Hydraulic buffer roller cage shoe

Technical Field

The utility model relates to a direction and buffer for mine hoisting container specifically are a hydraulic cushion roller cage shoe, and when promoting the container and taking place the horizontal hunting at the promotion in-process, when striking cage guide, the device can slow down or eliminate this kind of swing, makes the promotion container even running, and the guarantee promotes the operation safety of container, and the wide application belongs to the mining machinery field in the hoist system in the metallurgical mine in colliery.

Background

At present, in the coal mine metallurgical mine industry, in order to eliminate the swing of a lifting container in the operation process, a roller cage shoe is often installed on the lifting container, a spring or rubber or an oil cylinder is adopted as a buffer piece, and a hydraulic roller cage shoe (such as a hydraulic self-adaptive roller cage shoe ZL 201920753785.8 and a hydraulic buffer roller cage shoe CN201711147453.7) is a great progress on a spring roller cage shoe product.

Disclosure of Invention

The utility model aims at overcoming above-mentioned prior art's weak point, provide a hydraulic buffer roller cage shoe, it mainly comprises gyro wheel, support, base, buffer cylinder, adopts two-chamber structure in the buffer cylinder, constitutes first chamber by piston and endotheca, and second chamber is constituteed to piston and sliding sleeve, cylinder cap, by piston groove intercommunication between first chamber and the second chamber, when the gyro wheel receives the striking, the first chamber fluid of piston downshifting compression gets into second chamber, realizes the buffering.

The utility model discloses a realize with following technical scheme: the utility model provides a hydraulic buffer roller cage shoe, characterized by: the buffer oil cylinder comprises a cylinder barrel, wherein the inner ring surface of the cylinder barrel is tightly attached to the outer surface of a sliding sleeve, an upper spring is arranged on the sliding sleeve and fixed on a cylinder cover, a lower spring is arranged below the sliding sleeve and fixed on a cylinder base, the inner surface of the sliding sleeve is tightly attached to the outer surface of an inner sleeve, the inner sleeve is fixed on the cylinder base, an oil hole is formed in the cylinder base, the inner surface of the inner sleeve is tightly attached to a piston, the bottom surface of the piston, the inner surface of the inner sleeve and the cylinder base form a cavity A, the piston, the inner sleeve, the sliding sleeve, the cylinder barrel and a cylinder.

The piston groove adopts a variable cross-section V-shaped groove.

And the upper spring, the sliding sleeve, the lower spring, the piston and the hydraulic oil in the cavity A and the cavity B form a cage guide deformation adaptive system.

The utility model has the advantages that: this hydraulic buffer roller cage shoe simple structure is compact, required part is few, easy manufacturing, easily realize batch standardization production, greatly reduced manufacturing cost, the size of buffer power depends on the sectional area of piston groove, the buffer power is from dozens of kilograms to several tons all very easy designs, can do the bolster very little, no longer worry the restriction that promotes the container and arrange the space, under the condition that the cage guide warp, also can adapt to the cage guide and change and hug closely the cage guide, change the inside two-chamber buffering of single-cylinder into from the buffering of double-cylinder and intercommunication pipe-line system, be a simplification to hydraulic buffer roller cage shoe, can reach the buffering effect of current hydraulic buffer roller cage shoe equally.

Drawings

The present invention will be described in further detail with reference to the following drawings and examples:

fig. 1 is the utility model discloses a hydraulic buffer roller cage shoe structure schematic diagram:

in the figure: 1. the device comprises a roller 2, a wheel shaft 3, a support 4, a rotating shaft 5, a base 6, an upper pin shaft 7, a piston 8, a cylinder cover 9, an upper spring 10, a piston groove 11, a cylinder barrel 12, an inner sleeve 13, a sliding sleeve 14, a lower spring 15, a cylinder seat 16, a one-way valve 17, a lower pin shaft 18, a buffer oil cylinder 19, a cavity A20 and a cavity B.

Detailed Description

As shown in the figure: a roller 1 is connected with a support 3 through a wheel shaft 2, the support 3 is connected with a base 5 through a rotating shaft 4, the base 5 is connected with a cylinder seat 15 through a lower pin shaft 17, and the support 3 is connected with a piston 7 through an upper pin shaft 6.

The inner ring surface of the cylinder barrel 11 is tightly attached to the sliding sleeve 13, the upper part of the sliding sleeve 13 is provided with an upper spring 9, the upper spring 9 is fixed on the cylinder cover 8, the lower spring 14 is arranged below the sliding sleeve 13, the inner surface of the sliding sleeve 13 is tightly attached to the inner sleeve 12, the inner sleeve 12 is fixed on the cylinder seat 15, the cylinder seat 15 is provided with an oil hole, the tail end of the oil hole is provided with a one-way valve 16, the inner surface of the inner sleeve 12 is tightly attached to the piston 7, the bottom surface of the piston 7, the inner surface of the inner sleeve 12 and the cylinder seat 15 form a cavity A19, the piston 7, the inner sleeve 12, the sliding sleeve 13 and.
