Abstract

PURPOSE:To easily measure the gap between a guide shoe and a guide rail by providing support shafts off an extension line from the center of a scale to the center of a circular arc on a base plate with the circular arc scale, and providing the first and second pointers contacted with the guide rail at one end and indicating the scale at the other end on the support shafts. CONSTITUTION:A pair of support shafts 3 are pivotally supported at positions off the extension line of the center of the scale 1 of a bed plate 2 with the circular arc scale 1, and a pair of the first pointers 4 contacted with the side face of a guide rail R at one end and matched with the center of the scale 1 are provided. A measuring piece 5 reciprocateably contacted with the end face of the guide rail R by a spring is provided between the pointers 4, and the second pointer 6 pivotally supported by a shaft 7 is swayed by its reciprocating movement. When the measuring piece 5 is located at the center of the end section of a guide shoe S, the pointers 4 are magnified by the gap x1 with the guide rail R and indicated on the scale 1, and the pointer 6 is swayed by the gap of the end face of the guide rail R and indicated on the scale 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of application for business owner A) The present invention is directed to an elevator car formed between a guide rail that guides the vertical movement of an elevator car and a guide shoe disposed on the car etc. that engages with the guide rail. The present invention relates to a guide shoe measuring jig for measuring the size of a gap.

(Prior Art) An elevator device includes a car and a counterweight connected to the car via a lobe, and the car and the counterweight move up and down while being guided by a pair of guide rails arranged along a hoistway. It consists of a toothpick. The car and the counterweight are each provided with a guide shoe that engages with the guide rail, and when the car and the counterweight move up and down, frictional force is generated between the guide shoe and the guide rail. Conventionally, lubricating oil is regularly supplied to the guide rails to improve the slippage between them, thereby making the elevator car move smoothly up and down, and suppressing wear on both.

However, since the car is slightly deviated from the guide rail when going up and down, force and load force are applied when the car's guide shoe presses against the guide rail, causing the guide shoe and guide rail to wear out over time. However, as wear progresses, the engagement between the guide shoe and the guide rail becomes unstable.
There is a risk that raising and lowering the car will be hindered. Therefore, the progress of wear on the guide shoes and guide rails can be monitored by
Measurements were made as shown in the sy diagram. That is, the guide shoe (
1) is brought into contact with the negative side of the guide rail (2) to form a gap, and by inserting and removing a plurality of gap gauges (G) into and from this gap, the gap is determined by reading the total of the inserted gap gauges (6). The dimension (ΔXI) was measured. Such measurement work was carried out at four locations, and the end face of the guide rail (R>) and the guide shoe (S)
The gap between the guide shoe (S
) was used to visually read the remaining amount, etc.

[Problem to be solved by the invention]

To measure the gap dimension (ΔX+) between the guide shoe (S) and the guide rail (R),
1) to one side and bring the guide shoe (S) into contact with the negative side of the guide rail (R) to form a gap, which involves the complicated work of inserting and removing multiple feeler gauges (6). G) when inserting or removing the guide shoe (
There is a risk that dust adhering to the surfaces of S) and guide rails (R) will be pushed into the interior, and equipment, feeler gauges (G), etc. will be contaminated with lubricating oil, so it is time consuming to wipe them off. This made the measurement work troublesome.

The present invention was made to solve the above problems, and
It is an object of the present invention to provide a guide shoe measuring jig that can measure the amount of wear on the outer surface of a guide rail.

(Means for Solving the Problems) The guide shoe measuring jig of the present invention includes a base plate having an arcuate scale, and a direction from the center of the scale to the center of the arc on the opposite side of the arcuate scale of the base plate. A support shaft is arranged to be offset to one side from an extension line of A first pointer extending in the opposite direction to the scale so as to abut on the side surface, and a first pointer disposed adjacent to the first pointer on the extension line, one end of which moves forward and backward while abutting the end surface of the guide rail. and a second pointer that has a lever that comes into contact with the other end of the gauge head and is pivoted so as to swing in conjunction with the forward and backward movement of the gauge head. .

(Function) According to the present invention, after the guide shoe is brought into contact with one side of the guide rail, the mounting of the guide shoe is carried out by placing the base plate on the tool, bringing the gauge head into contact with the end surface of the guide rail, and attaching the base plate to the end surface of the guide rail.
After the pointer is brought into contact with one side of the guide rail, when the base plate is deflected, the first pointer shifts from the center of the scale to indicate the dimension of the gap between the guide shoe and the guide rail, and the second pointer moves away from the center of the scale. This indicates the dimension of the gap between the guide shoe and the end surface of the idle rail.

[Example] The guide shoe measuring jig of the present invention will be described below based on the example shown in FIGS. 1 to 6. Note that FIG. 1 is a plan view showing an initial state in which the dimension of the gap between a guide shoe and a guide rail is measured using an embodiment of the guide shoe measuring jig of the present invention, and FIG. 2 is a side view of FIG. 1.
