Description

one

The invention relates to an elevator construction, in particular, to devices for fastening a guide car or an elevator counterweight.

The purpose of the invention is to reduce the labor intensity of servicing the elevator by eliminating the remounting of the device.

FIG. 1 shows the proposed device g (working position of the breech), a general view; in fig. 2 - the same (non-working position of capture); in fig. 3 - the same, top view and horizontal section of the guide; in fig. 4 is a section A-A in FIG. one; in fig. 5 is a section BB in FIG. one.

The device contains a supporting element 2 embedded in the wall 1 of the shaft, on which the gripper 3 and the plate bracket 4 are installed, one of the vertical shelves of which forms the clamp 5 of the gripper 3, and the other shelf is a connecting link between the supporting element 2 and the gripper 3. The shelf 6 has a slit-shaped slot 7, through which the tail portion 8 of the gripper has been passed, having a central section 9 bent upwards, which prevents the gripping exit of the slot 7. The gripper 3 has shoulder 8 at the tail end 8 with the shelf 6.

To eliminate the need for increased accuracy in the manufacture and installation of the device, it is advisable to position the gripper 3 in its working position so that its end with a shaped groove that interacts with the base of the guide is located below the end that connects in the slot-like slot 7 with the shelf 6, and forms with a horizontal angle of o. 3-5 °. By virtue of this, under the action of the grip 3 of the horizontal load from the base of the guide 11, it presses its shoulders 10 to the vertical plane of the shelf 6 and tends to turn down relative to this point, thus eliminating the possibility of its spontaneous opening upwards.

When acting from the cabin on the guide 11 of the horizontal load in a plane located perpendicular to the plane of the tracks, the guide is kept from shifting.

nor due to the interaction of the base of the guide with the side surface of the working section of the profiled gripping groove. Moreover, in order to ensure that the guide is held in two opposite directions, the width of the shaped groove is equal to the width of the base with direction. The grip from the displacement down and from the lateral displacement in the horizontal plane is fixed by the open groove of the latch 5. In this case, in order to fix the grip from the lateral displacement from two directions, the width of the open groove of the latch 5 is equal to the width of the grip.

The tail portion of the grip is held from displacement in the horizontal plane by the vertical walls of the sipe, where it is positioned to be rotatable in the vertical plane.

Maintenance of the elevator with this design of the device for fastening the rail is carried out as follows.

For example, a spring buffer 12 of an elevator car 12 is placed on the rail 11, which can be used as a stop when servicing the elevator bin from the elevator. When the buffer 12 moves along the guide 11, the gripper 3 under the action of the buffer itself or previously by the servant's hand rotates in the hinge formed by the gripper shank and slot-like slot 7 in the shelf 6 at an angle at which the buffer 12 passes unhindered upward (Fig. 2) after which the grip 3 is rotated to the starting position by the action of its weight. At the end of the operation of the buffers as a stop at the level of the positioning of the support element with the grip, the buffer 12 is transferred to its lower level with the previously deflected grip 3, which is then re-installed in the working position defined by the latch 5, the open groove of which has a horizontal portion defining the position of the grip in the vertical direction, and the vertical sections that prevent the grip from shifting in the horizontal plane.
