Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a guide roller unit in a rail traveling crane, more specifically, a shaft, a guide roller,
The guide roller unit in the rail running by inserting the guide roller unit composed of the side plate of the crane device into the long groove-shaped shaft support formed on the working space side of the side plate of the crane device with the shaft assembled to the guide roller. Regarding improvement of technology that can be made into a unit.

[Prior Art] As is well known, as one of the cranes applied to factories and vehicles, there is a rail traveling crane having a rail as a traveling track surface. For example, overhead traveling cranes and hanging cranes are widely used. A guide roller runs on the running rail.

Although the guide roller used in the past is of a type that the structure runs on the upper surface of the shaft and the rail or the lower surface of the rail, the shaft and the roller are not used when the crane is assembled (construction) or the crane is disassembled (from the site to the factory). Since it is not designed to be detached from the rail as an integrated unit, it is very time-consuming to disassemble the rail, motor, and wiring when removing it. Therefore, a means has been proposed in which the completed unit of the guide roller and shaft can be attached to and detached from the traveling rail.

For example, it is proposed in Japanese Utility Model Publication No. 52-23792. That is, the traveling pulley and the side plate supporting the traveling pulley are separated from each other, a circular hole and a notch guide groove reaching the circular hole are provided in the side plate, and the shaft end supporting the traveling pulley is precisely fitted into the circular hole of the side plate. A crane in which a step shaft portion and a housing integrated with the step shaft portion are fixed, and a traveling sheave portion can be attached to a side plate which is previously attached and fixed to a crane saddle body.

[Problems to be Solved by the Invention] According to this conventional technique, the guide roller and the shaft can be attached to and detached from the traveling rail as a completed unit, which has an advantage that the crane can be easily disassembled and assembled. The present invention intends to solve the following points after obtaining this advantage.
That is, in the case of this type of technique, it is necessary to connect a pair of left and right side plates that support the left and right pulleys. In the prior art, the left and right side plates are maintained in parallel by a motor output shaft arranged below for driving the pulley. Connecting the left and right side plates with the motor output shaft arranged below in this way saves space when there is one beam such as an I-beam, that is, when the beam is arranged in only one direction. There is no particular problem in
If the beams are arranged in the other direction orthogonal to one direction, that is, in the X and Y directions, disposing the motor output shaft that connects the left and right side plates under the X direction beam will increase the space below. That is a problem in saving space. Therefore, the present application saves space when providing a guide roller unit structure that can be applied to a crane in which a beam is orthogonal to the X direction and the Y direction while taking advantage of the above-mentioned conventional technology.
The purpose is to provide a guide roller unit for a crane with beams arranged in the Y and Y directions.
