Description

Plate hook with detachable self-lubricating guard plate

Technical Field

The utility model belongs to the technical field of the board hook technique of can dismantling self-lubricating backplate and specifically relates to a board hook with can dismantle self-lubricating backplate is related to.

Background

As shown in figure 1, the guard plate of the prior gantry hook used for the casting bridge crane, the plate hook 2 of which is contacted with the trunnion of the ladle, is mostly a welded guard plate 1. At the transportation of ladle, turn over a packet in-process, friction always between the trunnion of ladle and welded type backplate 1 causes welded type backplate 1 wearing and tearing serious, and the later stage is changed the mode that can only adopt flame cutting, and improper operation and incised the board hook 2 appear easily in this kind of operation mode, and its maintenance is all very inconvenient.

Patent publication No. CN2156166Y discloses a copper lining tile for hook head of gantry hook, which is a semi-circular revolving body and is arranged at the hook core part of the gantry hook. The copper lining tile is embedded with graphite material, so that the copper lining tile has a wear-resistant effect. The problem that this patent exists lies in, the hook hanging face of plate hook includes hook point portion, hook core portion and hook rod portion, and each position all has the cambered surface of different curvatures, only sets up the copper bushing at hook core portion, then can not carry out effectual protection to hook point portion and hook rod portion. In addition, the connection between the copper lining tile and the plate hook is not reliable, and the copper lining tile may fall off after being heated.

SUMMERY OF THE UTILITY MODEL

In order to overcome not enough in the background art, the utility model discloses a board hook with can dismantle self-lubricating backplate adopts following technical scheme:

the utility model provides a board hook with can dismantle self-lubricating backplate for hang ladle trunnion, characterized by: a self-lubricating guard plate is connected to the hook hanging surface of the plate hook; the self-lubricating guard plate is divided into three sections which are respectively screwed on the hook tip part, the hook core part and the hook rod part of the plate hook through screws; be equipped with a plurality of through-holes on the face of self-lubricating backplate, install the graphite rod in the through-hole, the graphite rod is used for reducing ladle trunnion to the wearing and tearing of board hook hanging surface.

Further improve technical scheme, the cross-sectional shape of every section self-lubricating backplate is the U type, rides on the hook hanging surface of board hook.

According to the technical scheme, each section of self-lubricating guard plate consists of a cover plate and two side plates, and the two side plates are connected to the two sides of the cover plate in a U shape; the through hole is arranged on the cover plate, and the side plate is in threaded connection with the plate surface of the plate hook.

The technical scheme is further improved, and the graphite rod is in interference connection with the through hole or is bonded with the through hole through glue.

Owing to adopt above-mentioned technical scheme, compare the background art, the utility model discloses following beneficial effect has:

the utility model discloses a self-lubricating backplate can dismantle the change fast through the screw, very big has made things convenient for the maintenance and the maintenance of board hook. Install the graphite rod on the self-lubricating backplate, the friction surface between hook package trunnion and the plate hook can be lubricated to the graphite rod, reduces wearing and tearing between them, improves life.

In addition, the self-lubricating guard plate comprehensively protects the plate hook, and the service life of the plate hook is prolonged.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms "front", "back", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, but do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

A plate hook with a detachable self-lubricating guard plate is used for hanging a steel ladle trunnion. As shown in fig. 2, a self-lubricating protector 3 is attached to the hook hanging surface of the plate hook 2. Because the plate hook 2 has a complex hook hanging surface, the self-lubricating guard plate 3 is divided into three sections which are respectively screwed on the hook tip part, the hook core part and the hook rod part of the plate hook 2 through screws. Like this, firstly make things convenient for the manufacturing and the dismouting of self-lubricating backplate 3, secondly carried out comprehensive protection to board hook 2, prolonged the life of board hook 2.

In order to reduce the abrasion, as shown in fig. 3, a plurality of through holes are arranged on the plate surface of each section of self-lubricating guard plate 3, graphite rods 4 are arranged in the through holes, and the graphite rods 4 are used for reducing the abrasion of the ladle trunnion on the hook hanging surface of the plate hook 2. When this plate hook hangs ladle trunnion, graphite rod 4 can lubricate the friction surface between ladle trunnion and plate hook 2, reduces wearing and tearing between them. In order to prevent the graphite rod 4 from falling, the graphite rod 4 is connected with the through hole in an interference manner or is adhered by glue.

If directly use the screw with the spiro union of self-lubricating backplate 3 on the hook hanging surface, through the wearing and tearing of a period of time, the head of screw also can wear out, is unfavorable for the screw like this and can dismantle the changing of backplate 3. For this purpose, each section of the detachable guard plate 3 has a U-shaped cross section and straddles the hook hanging surface of the plate hook 2. Specifically, every section can be dismantled backplate 3 and all constitute by a apron and two blocks of curb plates (the hook core section can be integrated into one piece), and two blocks of curb plates are the U type and connect in the both sides of apron. The through hole is arranged on the cover plate (on the front surface), and the side plate (side surface) is screwed on the plate surface of the plate hook 2 through a screw.

The part of the utility model not detailed is prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
