Description

FIELD OF THE INVENTION

This invention relates to a method of mounting an elevator bracket, in particular an elevator rail bracket, and to the field of technology related to passenger lifting devices.

BACKGROUND

Typically, the role of the elevator rails is to limit the degree of freedom of the elevator car and the counterweight, as well as in the direction of the elevator car and the counterweight when moving in the vertical direction. Brackets for rails are supporting parts for rails, the role of which is to fix the spatial position of the rails and to counteract the load from the rails. The stability of the rail bracket design is very important for the normal operation of the elevator.

In FIG. 1 shows the elevator car guides and the elevator counterweight with a speed limiter without a catcher. The guides have a portal frame design, with one end on the left and right supporting shoulders 1, 1 'being fixed to the shaft wall, the other ends of the left and right supporting arms 1, 1' are separately rigidly connected to the two ends of the supporting elements. The inner surface of the support arms 1, 1 'directly clamps the pressure guide plate 4 used to mount the counterweight guides, while the outer surface of the support element directly clamps the pressure guide plate 5 used to mount the guides of the elevator car. In the case of elevators in which it is necessary to install speed limiters with catchers, since space is required for laying the steel cable of the speed limiter with a catcher, it is impossible to directly use the brackets of the elevator guides with a speed limiter without pre-installed catchers.

SUMMARY OF THE INVENTION

The present invention is directed to the creation of multifunctional brackets for elevator guides, which can be used both with elevators with speed limiters without catchers, and with elevators with installed catchers and speed limiters, thereby reducing the cost of manufacturing guide rails and maintenance costs.

To solve this problem, a method for mounting the bracket for the elevator rails is proposed, the bracket comprising the left and right support arms fixed during installation on one side of the shaft wall. The corresponding elongated left and right support elements are separately secured to the left and right support shoulders, the left support element is connected to the left support shoulder by the connecting plate, the connection plate has connection positions that ensure that the left and right support elements are aligned and offset. The inner surface of the right support arm directly fixes the pressure guide plate used for mounting the counterweight guides, the inner surface of the left support arm with the support plate secures the pressure guide plate used for mounting the other counterweight guides. The base plate has mounting positions that provide the positions of the other counterweight guides near or away from the left support arm. The outer surface of the right support element directly clamps the pressure guide plate used for mounting the elevator car guide. If the connecting plate is in the connection position, ensuring the coincidence of the left and right support elements, then the supporting plate is in the mounting position, ensuring the placement of the guides for the counterweight near the left supporting shoulder, while the end surfaces of the left and right supporting elements are connected directly, and if the connecting plate is in the connection position, providing displacement of the left and right support elements, then the support plate is in the mounting position, bespechivaet removal guide for the counterweight of the left support arm, wherein the end face of the left and right support elements are connected to the transition support member.

Thus, if the left and right support elements are in a state of direct connection, then the dimensions of the structure correspond to the existing technical solutions, therefore, they are suitable for elevators with a speed limiter without catchers. If the left and right support elements are connected in an offset state, the connecting plate is shifted, while using the offset of the connecting plate and the transition support element ensures that the transverse and vertical space for the passage of the steel cable of the speed limiter with the catcher is freed up in the interior of the bracket, therefore this the bracket for the elevator guides can be easily used as an elevator bracket with a speed limiter with catchers that provides convenience and versatility.

In addition, according to the invention, it is provided that the connecting plates have two groups of mounting holes providing a direct and offset connection of the left and right support elements.

In addition, the end surfaces of the left and right support elements can have connecting plates elongated in one direction, while the two ends of the transition support element are connected to the end plate through the butt plate of the left and right support elements after displacement.

In addition, according to the invention, the end connections of the left and right support arms can have support angles.

DETAILED DESCRIPTION OF THE INVENTION

An example of implementation 1

In FIG. 2 and 3 show an embodiment of a method of mounting an bracket for elevator rails, in which the left and right support arms 1, 1 ', as well as the left and right support elements 3, 3' are made of a steel corner, and when mounting the left and right support arms 1 , 1 'steel support angles 2, 2', welded to one side, are fixed to the wall of the elevator shaft with spacer bolts. The other ends of the left and right support arms 1, 1 ′ are bolted to the left and right elongated support elements 3, 3 ′. In this case, the left support element 3 by means of the connecting plate 3-1 is rigidly connected to the left support arm 1, the connecting plate 3-1 has two groups of mounting holes, so the left support element 3 has a direct connection position (see Fig. 2) and position offset connection with the support element 3 '(see Fig. 4). The inner surface of the right support arm 1 'directly clamps the pressure guide plate 4, used for mounting the guides of the counterweight; wherein the inner surface of the left support arm 1, using the support plate 5 having mounting positions near the left support arm and at a distance from it, holds the pressure guide plate 4 used for mounting the counterweight guides. The outer surface of the right support element 3 'directly clamps the pressure guide plate 6, used for mounting the guides of the elevator car.

If these brackets are used in elevators with speed limiters without catchers, as shown in FIG. 2, the connecting plate 3-1 is in the connection position, ensuring the coincidence of the left support element 3 and the right support element 3 '; the support plate 5 is in the mounting position near the left support arm 1; the end surfaces of the left and right support elements 3, 3 'have butt pads elongated in one direction, while the two butt pads are combined and secured with bolts.

If these brackets are used in elevators with speed limiters with catchers, as shown in FIG. 3, the connecting plate 3-1 is in the connection position, providing displacement of the left support element 3 and the right support element 3 '; while the connection with the left supporting shoulder 1 is carried out using bolts. At this time, the left support element 3 is turned outward by 180 °, the butt plate of its end surface is turned outward and displaced with the butt plate of the right support element 3 '. The support plate 5 is displaced while in the connection position, remote from the left support arm 1. The end surfaces of the left and right support elements 3, 3 'should only be connected through the transition support element 8. The two ends of this transition support element 8 are bolted to the end plate and the butt plate of the left and right support elements 3, 3 'after displacement. Therefore, a slight change in the position shown in FIG. 2, to obtain the necessary space for the passage of the steel cable 7 of the speed limiter with catchers inside the angle of attachment of the left support arm 1 and the left support element 3. Due to the use of multifunctional elevator guide brackets described in these embodiments of the invention, when used for installation in elevators with speed limiters with catchers, it is possible not to change the initial mounting position of the guides.

From this it can be seen that both types of mounting can be used for widespread elevator rail brackets, which expands the scope of the present invention.

In addition to the above examples, the invention may be applied in other ways. Any technical solutions containing the replacement of signs with similar or equivalent are included in the scope of legal protection of this invention.
