[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint holding tool for holding the joints of upper and lower guide rails when vertically connecting guide rails of an elevator.

[0002]

2. Description of the Related Art Conventionally, when connecting both end surfaces of an elevator guide rail to each other, a lowering guide rail is usually erected at a fitting portion of its upper end surface by a lifting device such as a winch. Fit the lower end surface of the upper guide rail that was lifted up, attach the joint plate to the mounting surface of the guide rail,
Bolts are inserted into bolt holes formed in the seam plate and the guide rails and tightened, and the ends of the upper and lower guide rails are connected via the seam plates.

[0003]

Conventionally, when the end faces of the upper and lower guide rails are connected, even if the upper guide rail is lifted by a winch, the upper and lower connecting portions are inevitably bent in a V shape and the joint plate is a guide rail. It takes a lot of work to insert and tighten the bolts on the back of the, for example, a metal plate is used to temporarily tighten it with a vise, and after correcting it in a straight line, the bolts are tightened. However, the guide rails, each having a length of 5 m, had a problem that the connecting part was bent into a V shape even after tightening, making it difficult to perform centering work after that. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to facilitate the connecting work of the guide rails by the seam plate and to guide a large number of guide rails connected at a high position. The sliding surface of is also in a substantially straight line, so that the centering work of the guide rail in the next step becomes extremely easy, and the work efficiency is significantly improved.

[0004]

In order to achieve the above-mentioned object, a holding tool for a guide rail joint of an elevator according to the present invention is a substantially prismatic rail attached to one end portion on the long side of a substantially rectangular base plate. A support plate, a rail-holding slide plate of a substantially prismatic shape that slides in parallel with the rail support plate and the rail at a distance between the rail support plate and the rail, and is formed in a substantially T shape. A pressing base plate pivotally attached to a substantially central position of the base plate in a letter shape, and a handle pivotally attached in a V shape to push up a push-up plate loosely fitted to the central position of the press base substrate,
The tilt-stop plate that rotates the front side obliquely downward to the upper end side of the push-up plate and presses the rail-stop sliding plate with the press-fitting ring attached to the tip end, and the tilt plate of the press-stop base plate are opposite A pressure adjusting bolt for pressing the rail stopper slide plate is provided on the lower end side of the side.

[0005]

[Operation] After the upper end surface of the vertically positioned lower guide rail and the lower end surface of the upper guide rail suspended by a winch or the like are butted against each other and the recessed protrusion is fitted, the sliding surface of the guide rail is fixed. When the handle and the rail stop slide in parallel to each other and pull the handle downward (see Fig. 2), the push-up plate pushes up the rear end side of the tilt stop plate, and conversely the tip side of the tilt stop plate. Is projected diagonally inward and presses against the rail stop sliding plate, and the resistance reaction force of the rail stop sliding plate pushes the pressure adjusting bolt provided on the opposite side of the stop substrate to the rail stop sliding plate. The pressing slide plates are pressed toward the rail receiving plate side with a substantially equal pressure on the upper and lower sides, and the sliding surfaces of the upper and lower guide rails positioned inside the both are
The rail stop sliding plate and the rail receiving plate strongly sandwich from both sides, so the sliding surfaces of the guide rails are aligned on both sides, and by further pulling the handle strongly, the handle and the push-up plate are pivotally attached. Since the axis position is larger than the rotation axis of the handle and sticks out to the outer side position, the retaining ring is met by rail tightening, and the action line M of the resistance reaction force from the tilting retaining plate to the push-up plate is the tightening of the handle. The handle can be tightened in the tightening direction by changing the direction.

EXAMPLES Examples will be described with reference to the drawings. 1 to 4, the rail receiving plate 1 has a substantially prismatic shape, and is fixed to the surface of the substrate 2 along one end face of the substantially rectangular substrate 2 on the long side. The rail-holding sliding plate 3 has a substantially prismatic shape, and slide plates 5 and 5 for sliding in guide grooves 4 and 4 recessed inward from both ends in a direction perpendicular to the rail receiving plate 1 are provided. A rail holding space S is formed between the rail receiving plate 1 and the rail receiving plate 1 facing each other while always keeping the parallel state.
The retraction spring 6 is a spring for retracting the rail pressing slide plate 3 from the rail receiving plate 1 and retracting it, and is attached so as to be pulled in the retreating direction opposite to the rail receiving plate 1 (leftward in FIG. 1).

The pressure receiving face plates 7 and 7 are formed of iron plate pieces and are connected to the center position and the end portion of the rail pressing slide plate 3 via pressure stabilizing plates 8 and 8 formed of plastic or hard rubber. It is fixed to the outer surface 9 of the rail pressing slide plate 3 at a substantially central position. The pressing board 10 is formed by forming two iron plates formed in a substantially T-shape with a gap into which a handle or the like described later can be loosely fitted, and has a central bulging surface 11 inside and has a lateral T-shape. The upper and lower ends (upper and lower ends in FIG. 1) are pivotally attached to the rail pressing slide plate 2 side so as to be alternately tilted around the substrate pivot 12 at a substantially central position.

The handle 13 has a handle pivot 14 provided at a lower corner portion of an inner tip of the handle 13 at a substantially central position of the pressing base plate 10, and an upper corner portion of the inner tip of the handle 13 extends outward from the inner side. Install so that it draws an arc and rotates. The push-up plate 15 pushes the lower end side to the upper corner of the inner tip of the handle 13 and is pivotally attached outwardly in a V shape by a pivot shaft 16, and the upper end side is tilted upward to the outer side, and a tilting stop plate described later. And pivot. The tilting stop plate 17 is formed of a substantially rectangular iron plate whose long side is slightly elongated, and a substantially central position is located at the upper end of the pressing base plate 10 with a pivot 18 and upper and lower ends with a rail push centering on the shaft 18. A push ring 19 is pivotally mounted so as to tilt toward the non-slip plate 3 side, and a push ring 19 abutting against the pressure receiving face plate 7 is pivotally attached to the upper end portion of the tilt push plate 17, and an outer corner portion of the lower end portion. Is attached to the upper end side of the push-up plate 15 by a pivot 20. The pressure adjusting bolt 21 is screwed into the lower end portion of the pressing base plate 10 so that the tip end thereof contacts the lower pressure receiving face plate 7.

[0009]

Since the present invention is constructed as described above, it has the following effects. When connecting the ends of the elevator guide rails from above and below,
The sliding surfaces of the upper and lower guide rails can be firmly held in a straight line by simply gripping the ends of the upper and lower rails and pulling the handle downwards.Because there are no bends, the joint plates are attached. The work of contacting and tightening the bolt and the subsequent centering work become extremely easy, and further improvement of work efficiency can be expected.
