Abstract

The invention relates to devices for cleaning crane runways of construction tower and gantry cranes. The aim of the invention is to increase operational reliability. The device for cleaning the crane runways contains fine knives 1 mounted on the frame 5 on both sides of the rail, the bottom and side surfaces of which are made of elastic material. The cleaning knives are fixedly rotatable in the horizontal and vertical planes by means of bent L-shaped axles 3. The axes are placed in sleeves 2 and 4 fixed respectively on the cleaning blades and frame 5. When the crane moves, the knives are pressed to the side surface and the rail foot, producing cleaning them up. When moving in the opposite direction, the stripping knives are turned in the opposite direction. The rotation of the knives is limited by the stops 12, 13. 1C. f-ly, 3 ill.

Description

dzie.

The invention relates to devices for clearing the runways of building tower and gantry cranes from snow.

The purpose of the invention is to increase operational reliability.

FIG. 1 shows the device in the working position, front view; in fig. 2 - the device in the transport position, side view; in fig. 3 - the device at movement of the crane, the top view.

When the crane moves forward, the greater shoulder of the knife 1 under the influence of the snow load 10 moves back and, resting against the stop 12, stops, while the stripping knife is at an acute angle to the rail and clears the snowmobile zone.

Presence made by configuration

The device consists of a rectangular steel stripping knife with a rigidly fixed vertically on its surface ... ..

sleeve 2. In sleeve 2, freely dimensioned (laterally outlined) is elastic, one end of the L-shaped axis 3 is ensemble, the second end of the trimming knife is also loosely mounted in sleeve 4 fixed horizontally on

frame 5 chassis crane trucks. Lower and side adjacent to the knife side rail

It cleans snow from the railroad zone. When the crane moves in the opposite direction under the action of the load from the snow, the knives turn around (Fig. 3). In the winter

“. - - -. ..,. ,,

They are made of elastic material 6 (at 20 time of year the device is constantly located, for example, from a transport tape) secured by a pressure plate 7 to the knife. Fixing a cleaning knife in the working position is dried by locking device 8, which is mounted on the crane trolley.

Claims (3)

Invention Formula LIVED at i not; 5 da y and lu, / T4; viivvj oa- 1. Device FOR CLEANING RVLES Supported, respectively, on the frame 5, of crawler tracks, containing mobile cast in the sockets 9 and 10, the trolley and axle 3 are rigidly screwed. The knife 1 is secured in the transport position by the locking device installed in the socket 11 rigidly mounted on the frame of the crane truck. In order to limit the opening of the gate of the cleaning knife in the sleeve 2, when the crane moves under the effect of snow load on the larger knife shoulder, the stops 12 and 13 are rigidly fixed on the frame 5 of the undercarriage, which limit the turning of the knife sorama, on which the cleaning blades are fixed on both sides of the rail, supporting elastic elements for interacting with the side surfaces of the rail, characterized in that, in order to increase operational reliability, the stripping knives are hingedly mounted on the frame by means of L-shaped axes with the possibility of turning into horizontal horizontal and vertical planes and fixation in the horizontal plane, respectively, when the crane moves forward, the bone stops, which are fixed on the runner from both sides relative to the corresponding axis. The device works as follows. 2. The device according to claim. 1, characterized in that. The working body is mounted on the chassis, in order to increase convenience in operating the crane by installing an isotation, it is equipped with fixed hollowed L-shaped axle 3 in the sleeves 2 and 4 and 40 g with retainers for fastening the knives in stoppers in them, for example, with nuts from the axle-transport position. wowd mixture, yeni. To set the tool into working position, the latch 8 is inserted into slots 9 and 10, located respectively in the center of the chassis and on the axis 3. On each rail, two wiper blades are installed (one on each side of the rail), all in all, four knives are needed on the crane. When the crane moves forward, the greater shoulder of the knife 1, under the action of the snow load, moves back and, resting against the stop 12, stops, while the stripping knife is at an acute angle to the rail and clears the snowmobile zone. Presence made by configuration ... .. the rail (its lateral outline) elastic framing of the cleaning blade; the rail (its lateral outline) of the elastic framing of the cleaning blade ensures that the railroad zone is cleared of snow. When the crane moves in the opposite direction under the action of the load from the snow, the knives turn around (Fig. 3). In the winter LA. ,,  the time of year the device is constantly  the time of year the device is constant on the crane truck. Invention Formula crane tracks containing mobile a frame on which wiper blades are fixed on both sides of the rail, carrying elastic elements for interacting with the rail lateral surfaces, characterized in that, in order to increase operational reliability, the wiper blades are hinged on the frame by means of L-shaped axes that can be rotated horizontal and vertical planes and fixation in the horizontal plane by stops that are attached to the section n grue.Z
