Description

Elevator guide rail fixing device and fixing method thereof

The present invention relates to an elevator guide rail fixing device for fixing a guide rail installed vertically in an elevator hoistway to the hoistway wall, and more particularly to a structure for fixing the guide rail fixing device to the hoistway wall.

This type of guide rail bracket is usually fixed to the hoistway wall with two anchor bolts. However, since the hole in the hoistway wall for attaching the anchor bolt is opened by field work, it is necessary to allow some deviation. For this reason, the anchor bolt insertion holes formed in the bracket are often horizontally long holes, or one is a horizontally long hole and the other is a vertically long hole that is long in the vertical direction.

In such a configuration, when a lateral (horizontal) direction force (load) is applied to the bracket, the anchor bolt tightening and fixing portion (hereinafter referred to as fastening, etc.) consisting of a laterally long hole is only the holding force due to frictional force. It becomes. This holding force is small compared to the assumed force on the bracket. For this reason, there exists a problem that a bracket will slide sideways. When one of the two insertion holes is a vertically long hole, the above-described force is held by an anchor bolt that is inserted through the vertically long hole. However, since the allowable shear force of one anchor bolt is small compared to the assumed force on the bracket, there is a problem that the anchor bolt is damaged.

As a countermeasure against the above-mentioned problem, an elevator rail bracket device that limits the relative displacement of the guide rail by connecting the left and right rail brackets to each other with a connecting rod is known, for example, as in Patent Document 1 below. In this case, when a force is applied, a part of the force is transmitted to the opposite rail bracket through the connecting rod. This reduces the load acting on each rail bracket and limits the relative displacement of the paired guide rails.

However, as a problem of the above measures, it is necessary to use connecting rods, and to arrange support brackets for connecting rods on each bracket, so it is necessary to widen the hoistway space, and use in the case of narrow hoistways There is a problem that can not be.

Also, as another countermeasure, prepare a square washer with a round hole with a hole diameter close to that of the anchor bolt. And after making the hole for anchor bolt attachment in the hoistway wall, it fastens to the hoistway wall in the state which made the horizontal oblong hole of the fixing device which provided the anchor bolt separately, and the round hole of the above-mentioned washer inserted. After that, the fixing device and the washer are fixed by welding. Thus, when a lateral force is applied to the fixing device, the washer is welded and fixed to the fixing device, so that the force can be held by the anchor bolt inserted through the horizontally long hole. Such rail brackets are also generally known.

However, a problem with the above measures is that it is difficult to weld the fixing device and the washer in the field. Usually, welding by arc welding using a welding rod is performed locally. However, when welding the right and left sides and the lower side of the washer, it is difficult to form a sufficient fillet by dripping the molten member. Further, a horizontal piece extends inward of the hoistway from the upper end side of the vertical piece parallel to the hoistway wall of the fixing device. Thereby, when welding the edge | side on a washer, since the horizontal piece of a fixing device interferes, the welding by a hot rod becomes difficult.

Therefore, as a countermeasure against the above problem, the anchor bolt is temporarily fastened to the hoistway wall in a state of being inserted through the fixing device and the washer. Then, the position of the washer is recorded with a marking line or the like. Thereafter, the anchor bolt is removed once, and the right and left two pieces of the washer are welded in a state where the fixing device is placed on the ground, thereby enabling appropriate welding.

However, in the case of the above measures, there is a problem that the work procedure increases.

anchor bolts

2a and 2b are tightened so that one end of the washer 4 comes into contact with the washer support plate 3.

Due to the action described above, even in the wall side bracket with a wide oblong hole, no special work such as field welding is required, and after construction, lateral force (force from the direction where the washer support plate is located) However, it is possible to support with two anchor bolts without causing side slip.

Embodiment 2. FIG.
4 to 6 show an example of a wall side bracket portion of an elevator guide rail fixing device according to another embodiment of the present invention. 4 is a front view of the wall-side bracket 1aa, FIG. 5 is a washer 11, and FIG. 6 is a front view of the wall-side bracket 101a in a state where these are combined and fixed to the hoistway wall with

anchor bolts

2a and 2b.

As shown in FIG. 4, a washer welding plate 10 is fixed to the vertical piece 1c of the wall side bracket 1aa. The washer welding plate 10 is provided with a horizontally long hole 10a having the same shape as the horizontally long hole 1a of the wall-side bracket 1aa, and is fixed or integrally formed in advance so as to coincide with the horizontally long hole 1a.

As shown in FIG. 5, the washer 11 has a round screw hole 11a through which the anchor bolt 2a can be inserted, and a welding long hole 11b that is shifted downward and laterally from the round screw hole 11a. The washer 11 has a round screw hole so that when the round screw hole 11a and the horizontally long hole 10a of the washer welding plate 10 are overlapped, the upper end side of the washer 11 is below the upper end side of the washer welding plate 10 and can be welded. The position of 11a is determined. In the example of FIG. 6, the washer 11 has a shape shorter in the vertical direction than the washer welding plate 10 in order to align the position of the lower portion in the vertical direction.
That is, the washer 11 has a round screw hole 11a through which the anchor bolt 2a is inserted and a welding long hole 11b for welding to the washer welding plate 10. The round screw hole 11 a is positioned such that the end of the washer 11 on the round screw hole side is closer to the round screw hole than the end of the washer welding plate 10. The welding long hole 11b is located farther from the end on the round screw hole side than the round screw hole 11a.

As shown in FIG. 6, the assembly procedure begins with drilling holes in the hoistway wall 150.
Next, the side of the horizontally long hole 1a is the horizontally long hole 1a of the wall side bracket 1aa, the round screw hole 11a of the washer 11, the washer 6a, the spring 7a and the nut 8a, and the anchor bolt 2a is passed, and the side of the vertically long hole 1b is the wall side bracket 1aa. The

anchor bolts

2a and 2b are tightened through the vertically elongated holes 1b, washers 6b, springs 7b and nuts 8b, respectively, and the brackets 1aa and the washers 11 are fixed to the hoistway wall 150. Then, welding (welded portion) W is applied to the welding long hole 11 b and the upper end side of the washer 11.

With this configuration, when the wall side bracket 1aa receives a force in the direction of the arrow P in FIG. 6, the washer 11 restricts the movement of the washer welding plate 10 in the direction of the arrow, and the anchor bolt 2a has the washer. The movement in the direction of the arrow 11 is limited. As a result, the lateral movement of the wall side bracket 1aa can be restricted. Since the force in the direction of the arrow P is supported by the welded portion, the washer does not rotate, and there is no need to examine the strength against the axial pulling force when the washer rotates.
Further, not only the force in the direction of the arrow P but also the force from the opposite side to the direction of the arrow P is effective. That is, it is effective against the force from both sides in the direction in which the washer 11 and the washer welding plate 10 are provided.

In the above description, the case of the horizontally long hole 1a has been described. However, the movement of the wall side bracket 1aa, that is, the wall side bracket portion 101a can be restricted by applying the same configuration to the vertically long hole 1b on the right side of the drawing.
Further, as shown in FIG. 6, the washer welding plate 10 and the washer 11 have an elongated shape so as to protrude from the wall side bracket 1aa and extend so that the welded portion W is a portion without the horizontal piece 1d of the wall side bracket 1aa. Have. This is because the interference with the horizontal piece 1d of the wall-side bracket 1aa at the time of fixing and the welding member drooping (welding at a portion where the welding member does not droop) are considered.
However, in a situation where it is not necessary to consider these problems, the direction of the washer welding plate 10 fixed to the wall-side bracket 1aa is within the plane of the wall-side bracket 1aa (a surface orthogonal to the axial direction of the anchor bolt). In).

As described above, as shown in FIG. 6, the guide rail fixing device is fixed with the wall-side bracket formed by the horizontal elongated holes 1a and the vertically elongated holes 1b in a state where the

anchor bolts

2a and 2b are inserted into the wall-side bracket 1aa. After the positioning adjustment by the positioning margin of the part 101, the washer welding plate 10 and the washer 11 are welded by the round screw hole side edge of the washer 11 and the welding long hole 11b.

Due to the action described above, it is not necessary to consider the pulling force generated on the anchor bolt or hoistway wall by tightening the washer.After construction, the horizontal force (force from the direction where the washer welding plate is located and the opposite direction) ) Can be supported by two anchor bolts without causing side slip.

Embodiment 3 FIG.
