Description

[Detailed Description of the Invention] The present invention relates to an improvement of a transfer trolley suitable for point transfer in a trolleybus duct.
Conventionally, as this type of trolley, one in which a sled-shaped guide is provided on the trolley body has been proposed.
1 and 2 show the guide and the trolley equipped with the guide. On the bottom of the trolley main body 3, which has wheels 2, 2 on which the collector 1 is mounted,
A boat-shaped guide plate 4 is attached, and the boat bottom-shaped surface 4a of the guide plate 4 is made higher than the lower end of the wheel, that is, the running ground part to the duct, and the front and rear sled-shaped wide surfaces 4b,
When the trolley 4b protrudes in front and behind the wheels 2, 2 and enters the duct, one of the sled-shaped wide surfaces 4b is guided first, and then the trolley body enters, while when traveling inside the duct, only the wheels I'm trying to get it to run.

However, according to this conventional structure, since the guide plate 4 is attached to the bottom surface of the trolley body 3, the wheel accommodation grooves 4c, 4c, 4 provided on all sides are
It is necessary to process the holes 4d through which the connecting portion 6 of the terminal box 5 attached to the bottom of the trolley body 3 passes, and the holes 4e through which the guide wheels 7 pass, etc. It takes a lot of time,
Moreover, as the strength is reduced by such processing, it is easily deformed and has to be replaced frequently.

Furthermore, the guide plate 4 can only be replaced after removing the terminal box 5 and the plate 8 that supports the shafts of the guide wheels 7, 7, resulting in a large-scale work.

The object of the present invention is to provide a transfer trolley of this type which solves the above-mentioned drawbacks, requires less work on the guide, can increase its strength, and is extremely easy to replace.

In other words, the main point of the present invention is that when providing a guide on a wheeled trolley body, a guide is formed on both sides of the trolley body with a sled-shaped part formed on the long side edge, and the sled-shaped part is placed in front of and behind the wheels. In addition, the mounting structure is such that they are set higher than the grounding position of the vehicle.

The embodiment will be explained below with reference to FIGS. 3 and 4. In the figure, reference numeral 30 denotes a trolley body made of cast metal or the like, on which the current collectors 10, 10, 10 are supported by insulating holders 11, 11, 11, and four trolley bodies are placed at the front, rear, right and left positions. wheel 2
0, 20, 20, 20 are rotatably equipped.

Reference numerals 40 and 40 indicate guides, which are the main parts of the improvement of the present invention, and are made of steel plate or a plate-like material using a resin material with a small coefficient of friction, and are longer than the front and rear width of the wheel. , a sledge-shaped portion 42 is formed on one longitudinal side edge with arcuate slopes 41, 41 provided on both edges.

The guides 40, 40 are provided with screws 43, 4 on the left and right sides of the trolley body 30 in the running direction.
At this time, the sled-shaped part 4 on the side edge
2 is made to protrude further forward and backward of the front and rear wheels 20, 20, and is set higher than the running ground position of the wheels 20.

In the figure, 50 indicates each collector 10, 10, 1
0, a terminal box 70 and 70 are guide wheels, and 90 is a traction chain.

The present invention is constructed in this way, and the current collector 10 is in sliding contact with the trolley conductor B while the wheels 20,
When traveling in duct D at 20, 20, 20,
If the guide 40 is not involved with the duct D, and on the other hand, when moving from this running state to the next duct D', there is a step l between the ducts D and D', the guide protrudes forward from the wheels. The sled-shaped portion 42 (particularly the slope 41) of 40, 40 enters the duct D' while guiding and sliding, and then the front wheels 20, 20, followed by the rear wheels 20, 20, are held in a rolling position within the duct. This allows for smooth transfer without being shocked by steps.

Since the guides 40, 40 of the present invention are attached to both sides of the trolley body, they can be installed and removed completely independently of the terminal box, wheels, and guide wheels, and therefore replacement is very easy. There is also processing such as drilling holes and notches for the guide 40.
Since at least only the mounting hole 40a and the sled-shaped portion 42 need be processed, the processing effort can be significantly reduced.

Further, according to the present invention, since the guide 40 forms the sled-shaped portion 42 at its longitudinal side edge, for example, if the mounting hole 40a is a vertically elongated hole, the guide 40 may be shifted downwardly into the trolley body as it wears out. It is also possible to modify the position of the portion 42, thus significantly extending the replacement period for the guide. Furthermore, the guide 40 has the following characteristics due to its mounting manner.
It can be made thicker than conventional guides, and this allows it to be used with plastic molded bodies that have a relatively high degree of wear.Moreover, the height width can be increased relative to the thickness, and less machining is required. Therefore, the rigidity of the guide itself increases, making it difficult to deform due to the strong impact received when entering the duct.

As explained above, according to the present invention, the intended purpose is not only achieved by providing the necessary guide when transferring between groups, but also
This kind of transfer trolley can be provided which is advantageous in terms of maintenance and is also economically advantageous, and its practical value is enormous.
