Description of the Related Art Conventionally, as a trolley device, a trolley device is known in which a flanged wheel is mounted on side plates provided on both sides of a traveling rail. Since there is a possibility that smooth running may be hindered, various proposals have been made with respect to derailing measures.

In the conventional example 2), a groove and a projection are provided on the running surface of the rail and the wheel and the two are fitted together. In Japanese Utility Model Application Laid-Open No. 64-45687 (conventional example 3), the lifting prevention piece is provided with a side plate. Are formed integrally with the lower part of the lower part.

In each case, the side plate itself is worked and deformed so as to have a shape deviating from the standard specification of a commercially available trolley, and cannot be retrofitted, so that it cannot be adopted at least in existing trolleys.
【０００５】また、従来例２では車輪やレールに対して
突起ないし溝加工が必要となり、例えばレールについて

円滑な走行を阻害する原因になる。[0006] By the way, as a cause of hindering the smooth running of the trolley, there is also a case in which the wheels are worn away in addition to the derailing. Although the wheels of the trolley gradually wear out during use, the trolley may tilt and hinder smooth running, particularly if the wheels are unevenly worn. In the case of an electric trolley, such abrasion is significant if the trolley is still operated even after contacting the stopper at the end position of the traveling rail. Since not only the wheels but also the rail side of the running rail are worn, this also hinders smooth running.

A surrounding member having a surrounding shape is attached to an end of the side plate in the traveling direction.
In the hoist crane device that was
A pair of U-shaped members facing each other.

The size of the gap with the lower surface of the side plate is
It is set to a value corresponding to the allowable wear amount .

有意義である。Since the surrounding member is attached to the end of the side plate in the running direction, it can be easily attached to the side plate. Further, the surrounding member surrounding the periphery of the rail flange allows the lower side of the surrounding member to abut against the lower surface of the rail flange even when receiving an external force in an oblique direction, thereby preventing the side plate from being lifted up and preventing the wheel from coming off. Also, on the rail flange
Of the gap between the surface and the lower surface of the upper plate portion of the U-shaped member
Is set to a value corresponding to the maximum allowable wear amount of the traveling wheels.
Constant, wheel wear is constant (maximum allowable wear)
If it becomes larger, the upper side of the enclosing member slides on the rail to cause a running failure, thereby making it possible to mechanically detect the wheel wear limit. If the wear of the wheel exceeds a certain limit, it will be broken, which is meaningful in preventing this.

The packaging surrounding member, and a mounting member for attaching the side plate of the hoist crane, since there is provided a connecting member connecting the lower side of the enclosing member directly under the rail flange, easy attachment to the side plate of the enclosing member, the existing It can be easily attached to anything. Moreover, the surrounding member itself has a rigid structure in which the surrounding member is formed as a single block, and the surrounding member does not open outward even by oblique external force.

Wheels 3 are pivotally supported. The wheel 3 slides and rolls on the rail flange 1a and travels by hanging a chain block 5 on a pin 4 provided between the side plates 2 (traverse).
Is what you do. FIG. 2 illustrates an electric traverse type hoist crane, in which a traverse motor 6 is attached to the side plate 2 and an operation switch 7 for hoisting and traveling is provided. It may be. An enclosing member R is attached to the end of the side plate 2 in the running direction so as to surround the vicinity of the periphery of the rail flange 1a.

に検知できるからである。As shown in FIG. 1, the surrounding member R comprises a pair of right and left U-shaped members 8 which are symmetrically opposed to the rail web 1b (FIG. 3) when attached to the side plate 2. The U-shaped member 8 forms a rectangular or trapezoidal concave portion 8d between the upper plate portion 8b and the lower plate portion 8c and the upper plate portion 8b and the lower plate portion 8c projecting substantially vertically from the vertical plate portion 8a. It is made. As shown in FIG. 3, the recess 8d is provided with the rail flange 1 when attached to the side plate 2.
This is a space that can substantially surround the vicinity of the area a.
That is, the lower surface of the upper plate 8b is slightly tapered along the upper surface of the rail flange 1a so that a parallel gap a is formed between the lower surface of the upper plate 8b and the upper surface of the rail flange 1a. I have. The size of the gap a between the two is preferably set to a value corresponding to the maximum allowable wear amount of the wheel 3. This is because when the wheel 3 is worn to the maximum allowable wear amount, the lower surface of the upper side plate portion 8b slides on the rail flange 1a to deteriorate running performance, so that the degree of wear can be detected mechanically.

に支障を来さないようにするためである。On the other hand, a gap b formed between the upper surface of the lower side plate portion 8c and the lower surface of the rail flange 1a is set to several millimeters. This is because even if the side plate 2, that is, the wheel 3, is going to float when an external force is applied to the hoist crane in an oblique direction, the upper surface of the lower side plate portion 8 c hits the lower surface of the rail flange 1 a to prevent excessive lifting and remove the wheel. This is to prevent wheels from hindering traveling.

である。It should be noted that the lower side plate portions 8c of the pair of opposed U-shaped members 8 constituting the surrounding member R are not normally in contact with each other, and therefore they are not formed as an integral body. Replaces the surrounding member R with two U-shaped members 8
With this configuration, the hoist crane can be easily attached to the side plate 2 even after the hoist crane is mounted on the rail. Therefore, it can be retrofitted to an existing hoist crane.

Are drilled. The mounting member 9 has a rectangular recess 9b.
Is provided to avoid interference with the guide roller 15 (FIG. 4) sliding on the side surface of the rail flange 1 a provided on the side plate 2.

The lower side plate portions 8c are attached by nuts 12, and connect the U-shaped members 8 facing each other. In the figure, 8e is a bolt hole provided in the lower side plate portion 8c, 10e
a is a bolt hole provided in the connecting member 10 and is a long hole. 13 is a washer. By providing such a connecting member 10, the two U-shaped members 8 are formed as one integrated assembly block, which forms a rigid structure by itself. Therefore, even if an external force is applied in an oblique direction, the surrounding member is prevented from opening outward.

Is protected and the degree of wear due to idling is reduced.

Since the surrounding member is attached to the end of the side plate in the running direction, it can be easily attached to the side plate. Existing hoist crane can be easily installed. Further, when the wear of the wheel becomes larger than a certain value (maximum allowable wear amount), the gap is set so that the upper side of the surrounding member is in sliding contact with the rail, so that it is possible to mechanically detect the wheel wear limit. Since the surrounding member is constituted by a pair of U-shaped members facing each other, the structure becomes simple.
