Abstract

The utility model relates to a device for fixing a horizontal wheel of a crane, which comprises an upper limiting board and a lower limiting board. The upper limiting board and the lower limiting board are mounted on the lateral side of a horizontal wheel support, an open groove allowing a horizontal wheel shaft to be transversely taken out is arranged on each of the upper limiting board and the lower limiting board, and positioning parts for sealing the outer ends of the open grooves and fixed through a connecting part are further arranged on the upper limiting board and the lower limiting board. By means of the device for fixing the horizontal wheel of the crane, the wheel shaft for fixing the horizontal wheel can be directly taken down from the open groove without hanging supports, and thereby the device is quite simple in structure and quite convenient in maintenance, and manpower and material resources can be reduced.

Devices for securing horizontal wheels of cranes

technical field

The utility model relates to a device for fixing the horizontal wheel of a crane.

Background technique

Bridge cranes are widely used in various fields such as industrial and mining enterprises, steel and chemical industry, ports and terminals, and logistics turnover. Bridge cranes are usually composed of a crane, a running mechanism, and a bridge metal structure. Among them, the metal structure of the bridge includes the main girder and the end girder, and wheels are installed at both ends of the end girder to support the bridge running on the elevated, and the rails are welded on the main girder for the operation of the crane. During the process of hoisting goods by the bridge crane, the wheels will gnaw and cut the track, resulting in sliding friction between the wheel tread and the wheel rim and the track, which will cause serious damage to the wheel and track.

In order to avoid sliding friction between the wheel tread and the wheel rim and the track, a solution adopted in the prior art is to set a horizontal wheel on both sides of the track respectively. Contact with the track first and bear the lateral force, that is, use the rolling friction between the horizontal wheel and the track to avoid the sliding friction between the wheel tread and the wheel rim and the track, so as to prolong the service life of each component. However, in the prior art, the horizontal wheel is fixed on the wheel axle, and the wheel axle is fixed on the bracket through the limiting plate. Although the structure of fixing the horizontal wheel in this way is relatively simple, because the horizontal wheel is a vulnerable part, when the horizontal wheel wears and needs to be replaced, it must rely on other hoisting to lift the bracket together with the horizontal wheel to the ground in order to fix the horizontal wheel. Repair or replace. Thus it can be seen that adopting this method of fixing the horizontal wheel not only wastes manpower and material resources, but also takes a long time for maintenance, resulting in a significant increase in maintenance cost.

Contents of the invention

The purpose of the utility model is to provide a device for fixing the horizontal wheel of a crane which solves the problems of inconvenient maintenance and cost by directly disassembling the horizontal wheel.

The device for fixing the horizontal wheel of the crane proposed by the utility model includes an upper limit plate and a lower limit plate installed on the side of the horizontal wheel bracket. The slot that has been taken out, and the positioning piece fixed by the connecting piece for closing the outer end of the slot.

The positioning member is composed of a rectangular plate with an arc-shaped recess inside, and the rectangular plate is fixed on the upper limit plate and the lower limit plate by the connecting piece. A protective cover for protecting the horizontal wheel is also installed on the lower limiting plate.

The device for fixing the horizontal wheel of the crane proposed by the utility model is only provided with slots on the upper limit plate and the lower limit plate. There is no need to lift the bracket, so the structure of the device is quite simple, the maintenance is quite convenient, and manpower and material resources can be reduced.

Description of drawings

Accompanying drawing 1 is the appearance structure schematic diagram of an embodiment of the device for fixing the horizontal wheel of the crane proposed by the utility model;

Accompanying drawing 2 is a schematic diagram of the external structure of the horizontal wheels of the crane in Fig. 1 .

Detailed ways

Referring to Fig. 1 and Fig. 2, these two accompanying drawings show the appearance overall structure of an embodiment of the device for fixing the horizontal wheel of the crane proposed by the utility model. The device includes an upper limit plate 2 and a lower limit plate 3 installed on the side of the horizontal wheel bracket 1, a positioning part 4 and a connecting part 5. Among them, the upper limit plate 2 and the lower limit plate 3 are provided with slots 21 and 31 that allow the horizontal axle 6 to be taken out laterally. The positioning member 4 is composed of a rectangular plate, and an arc-shaped The recess 41 , the arc-shaped recess 41 and the slots 21 and 31 on the upper limit plate 2 and the lower limit plate 3 can be combined to form a circle to clamp the horizontal axle 6 . The connecting piece 5 can adopt bolts, and the positioning piece 4 is fixed on the upper limit plate 2 and the lower limit plate 3 by bolts. A protective cover 8 for protecting the horizontal wheel 7 is also installed on the lower limiting plate 3 .

When the horizontal wheel 7 needs to be repaired or replaced, the first choice is to take off the connecting piece 5, the positioning piece 4 and the protective cover 8 in sequence, and then the horizontal wheel shaft 6 can be removed from the slot on the upper limit plate 2 and the lower limit plate 3. 21 and 31 directions are taken out horizontally, and the horizontal wheel 7 can be repaired or replaced.
