Abstract
The utility model relates to a brake friction plate for a hoisting winding drum for an internal combustion tire-type crane. The brake friction plate comprises a friction plate body, wherein the outer curvature radius of the friction plate body is identical to the inner circle radius of a repaired winding drum, and fixed screw holes are formed in the outer curvature surface; the fixed screw holes in the outer curvature surface of the friction plate body are uniformly distributed on the outer curvature surface; and the friction plate body is made of a resin substrate. According to the brake friction plate, the inner curvature radius of the friction plate body is identical to the outer circle radius of the repaired winding drum, and the fixed screw holes are formed along the outer curvature surface, so that the technical problem of wear-in of a new friction plate and a used winding drum is solved, and the service life is prolonged; and the friction plate is made of the resin substrate, the resin substrate is an environment-friendly material and basically causes no environmental pollution when used, the friction coefficient of the material at the temperature of 300 DEG C is stable, and almost no changes exist at the same time. Besides, the wear rate of the material at the temperature of 200 DEG C is very low, and testing data display that the service life of the material is 3-5 times s longer than that of a rock wool material under a normal condition.
Description
Technical field
The utility model relates to a kind of brake strip, especially a brake strip for hoisting drum of crane.
Background technology
principal commodity was log and coal in recent years, in the log operation, 25 tons of internal combustion rubber tired cranes as log place operation major equipment, the use general status is good, but, increase along with period of service, the frequency of fault is also in continuous increase, the hoisting system of crane particularly, due to long use, the hoisting drum surface is because of long-term and friction lining friction, surface abrasion and its groove all become more and more serious, accordingly, the replacement frequency of friction lining is also improving constantly, and because of the unfairness of mandrel surface, might contact bad with reel hoisting of more renewing because of friction lining during friction lining, there is certain potential safety hazard.
The safety of using at the scene for assurance equipment, the repairing number of times and the parking period that reduce the expenditure of repair cost and increase because of more renewal of facing renewal, reel, need to the braking of hoisting system be improved with friction plate structure and material, and hoisting drum is repaired, reduce the fault of hoisting system on reel and friction lining, eliminate consequent potential safety hazard.
Summary of the invention
The utility model is that a kind of brake strip for internal combustion rubber tired crane hoisting drum will be provided, and is used for reducing the fault of hoisting system on reel and friction lining, eliminates hidden danger on consequent safety.
The technical solution of the utility model is: a kind of brake strip for internal combustion rubber tired crane hoisting drum, comprise the friction lining body, friction lining body outer curvature radius with repair after reel in radius of circle identical, and along having fixing threaded hole on the extrinsic curvature face.
The friction lining body thickness is 10mm.The fixing threaded hole of friction lining body extrinsic curvature face is uniform on curvature surface outside.The friction lining body is made by resin substrate.
The beneficial effects of the utility model are:
Friction lining body outer curvature radius of the present utility model with repair after reel in radius of circle identical, and along having fixing threaded hole on the extrinsic curvature face, solved the technical matters of the break-in of new friction lining and old reel, extended service life; Friction lining adopts resin substrate to make, and this material is environment-friendly materials, uses substantially pollution-freely to environment, and the data display life of test is under normal circumstances than the long 3-5 of asbestos friction material times.
Description of drawings
Fig. 1 is structure cutaway view of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As Fig. 1, shown in 2, a kind of brake strip for internal combustion rubber tired crane hoisting drum comprises the friction lining body, friction lining body outer curvature radius with repair after reel in radius of circle identical, and along having fixing threaded hole on the extrinsic curvature face.
The friction lining body thickness is 10mm.The fixing threaded hole of friction lining body extrinsic curvature face is uniform on curvature surface outside.The friction lining body is made by resin substrate.
25 tons of internal combustion rubber tired cranes that the utility model is used for imperial Wu's ancillary firm be all that Harbin Institute of Engineering mechanical limited liability company system makes, model is QLY25, there are 13, in case reel and the friction lining et out of order of original hoisting system, generally adjust, can not if adjust, can only change reel or friction lining, single friction lining that hoists of changing, although repair time is shorter, but there is the break-in problem of new friction lining and old reel, the new reel of while relative usage, use the friction lining period of service of old reel also short, as reel and friction lining are all changed, not only repair time is long, and cost of repair is also larger.
Because the friction plate structure that adopts matches with reel after reparation, solved the technical matters of the break-in of new friction lining and old reel, and increased the thickness of friction lining, the service life of prolongation; With material be ep-type material, reduced simultaneously the harm to environment and human body.
At present, used the friction lining of 3 cover new materials and the reel of 5 cover reparations to use on 25 tons of Kazakhstan work cranes, condition of service is good, the abrasion loss of friction lining and the abrasion loss of reel are all good than the friction lining that adopts old material, the abrasion loss of reel there is not wearing and tearing according to observations substantially, has reached the purpose of expection.
