METHOD AND TESTING EQUIPMENT FOR LIFT GRAPHIC EQUIPMENT

This invention relates to the preamble of claim 1; and the testing apparatus for an elevator gripper device according to the preamble of claim 2, in particular for a gripper device due to the loosening of the elevator rope.

The elevator car passes through the guides in the elevator shaft guided by roller or slider guides. When the elevator speed becomes too high, for example, grasping devices fitted to the elevator car unit, which grip the guides in the elevator shaft, are used. Some lifts, particularly rope-supported hydraulic lifts, use a gripper device which is activated by loosening the 15 ropes. Typically, such a grasping device receives the driving force required to initiate the adhesion from a spring in the carrier rope fastening of the carrier rope, which is loaded with a load applied by the elevator car to the rope attachment of the rope in question. Each rope has 20 bows. Thus, when loosening any of the ropes associated with the rope attachment, it will release the driving force required to begin bonding. When the rope loosens, that is, when the rope stops supporting the elevator car, the spring load is released, releasing propulsion to trigger the clamp, • ·. 25 as a result of which the elevator sticker.

• · · * · · «M ·« · · ···; The reliability of the loose rope grippers has been checked by checking the functions of the different parts separately. However, such a · ·: ** procedure does not adequately reflect the actual situation • · V '30 and may give a misleading picture of the reliability of the gripper device in the actual situation. Testing a loose rope grabber • · · · * '*; loosening, such as a rope • · ·. detachment or breakage in a resembling test set-up is «« · 35 cumbersome and even dangerous. If the installer were to loosen the rope while driving the • · '· ”*, he / she would have to do it himself / herself: in the elevator shaft, for example, on the roof of the elevator car, his safety might be compromised.

The object of the present invention is to eliminate the drawbacks of the prior art and to provide a completely new type of testing apparatus for testing the elevator's gripper device. The method of the invention and the apparatus of the invention activate the gripper device by removing the load exerted by the elevator rope on the rope attachment in the elevator car. Equipment-specific features are detailed in the appended claims.

The invention makes it possible to simulate a situation in which one or more ropes become loose as if the rope were to be severed or released. The testing apparatus according to the invention can facilitate the testing of the gripper and make the testing more secure. The apparatus according to the invention may be located in an elevator car unit at the top thereof. The equipment can be adapted to any of the elevator ropes.

In the following, the invention will be described in more detail with reference to the foregoing drawings, with reference to the accompanying drawings, in which Fig. 1a illustrates a testing apparatus in the elevator car unit according to the invention Fig. 2 shows the test apparatus after activation ♦ ♦ · ♦ · · 30 and Fig. 3 illustrates a rope-suspended hydraulic lift.

M1, «• Figures 1a and Ib show a testing apparatus for testing the gripper device located vertically at the top of the periphery of the elevator car unit. It has a body part 2 mounted on the upper end of the vertical portion 1 of the circumference 1 and having a horizontal axis 3. Horizontal axle 105177 is mounted on the rope 4 by means of a clamping member 5. a pivoting cam 6, which in Fig. 1a is in an obliquely upright position before being released with the rope straight. At the other end of the shaft 3 is provided a locking ring 7, 5 with a notch 8 at its lower part. In the position shown in Fig. 1a, before the rope 4 is straight, notch 8 is fitted to the lower part of the body 2 which, prior to activation, is in a horizontal position and prevents the cam 10 from being pivoted downwardly by its rope 4, for example to the horizontal position shown in Fig. 2. To activate the test apparatus, a plate-like release stop 12 is attached to the guide 11 in the elevator passage at a suitable position. The body part of the apparatus consists of a body plate 13 having at both ends housing parts 14 facing the elevator rope 4, between which an axis 3 is disposed, whereby the body part can be fastened to the upper end of the upright part 1 for testing. The stop 12, on the other hand, has a fastening plate 15 for fastening it, for example, by screw mounting behind the guide 11, and a stop part 16 bent towards the test apparatus, which has a bottom view and a portion of the fastening plate 15.

: 25 M · • The equipment is used for testing as follows: · · · ·

One of the lift ropes 4 is secured by means of testing equipment j ·. the elevator car. In the past, the rope is attached to the • · ·] *: ·. via rope fastening. Thus, when the rope is secured at various points to the elevator car by means of a rope attachment and testing device, the rope is disengaged in its lifting cylinder or - ♦ · * ··· * otherwise fixed at the point of attachment to the shaft.

• · · «*

To prevent the loosened rope from becoming fully powered, the • rope shackle secures the end of the rope leaving the rope loose.

«·« · 35 This way the rope does not support the elevator car, but due to the • * · coating of the tester, the rope attachment in the basket still feels tight. The testing apparatus provides a force sufficient for the rope attachment of the rope in question to keep the spring load in the rope attachment high enough to prevent sticking even when the rope is loosened to support the weight of the elevator car. When the rope used for test 5 is loose, the weight of the elevator car rests solely on the other support ropes. The apparatus is used to activate the clamping device by releasing the load of the rope attachment provided by the tester, whereby the unloading force exerts a 10 clamping action. The release is effected by driving the elevator car downwards and allowing the trigger 10 to collide with the stop 12. The pull of the cam 6 on the rope 4 and the rope attachment via the rope ceases. Since the rope is loosened from the attachment at one end, the loose rope 15 can follow the spring loading of the rope attachment and activate the adhesive. Activation is performed at a predetermined height in the elevator shaft. The apparatus is designed to operate at any one of four possible positions of the rope 4 on the axis 3, whereby the operation of the apparatus is independent of the slack of the rope by which the gripper is intended to be released.

During the test, the trigger mechanism is fixed directly to the upper part of the perpendicular part 1, and the tensioner 5 is fastened thereto::: 25 to the rope 4 used in the test. The cam 6 can be • arranged in different positions on the axis 3, so that the rope to be used can be freely selected.

• · • · • · ·] ·; ·. The elevator is guided to travel from the higher floor level to • · 30 test floor levels. As the elevator moves downward ... toward the elevator shaft and the trigger lever 10 hits • · the release stop 12 disposed at a predetermined • · ·. dashed in Fig. la, and allows cam 6 to rotate • · ·. ·. horizontal, whereby the tension of the rope 4 is released as shown in Fig. 2 · · '· 1 ·'. A loose rope in the elevator car • · • i «5 The 105177 grab function detects a loose rope and causes the properly functioning grabber to work. The tensioning of the rope against the rope attachment in the rope basket by means of the cam 6 is advantageous to make the rope tension 5 greater than normal, whereupon the rope can be re-tensioned after testing, which facilitates re-attachment of the loosened rope to the anchorage.

Fig. 3 is a reference showing a rope-mounted hydraulic lift 10. The elevator car 21 is suspended by the elevator ropes 4. The elevator ropes 4 are secured to the elevator car 21 in the rope basket attachment 23 via springs 24. At its other end, the ropes 4 are rigidly attached to an anchorage point 27 relative to the elevator shaft. The ropes are supported by a ratchet wheel 28 driven by the hydraulic cylinder and mounted on the hydraulic cylinder 22 supported by the elevator shaft 15. The elevator car has a gripper 26 which is activated by the lever assembly 25 if the rope 4 becomes loose, thereby releasing the compression of the spring 24 or its parallel spring 20 to affect the lever assembly.

It will be apparent to one skilled in the art that the various embodiments of the invention are not limited to the example above, but may vary within the scope of the following claims.
