In the illustrated example, a pair of first adjustment oblong holes 2131 facing each other are provided in the lower mounting plate 213, and the first fastening member 2132 may be a structure in which a fastening bolt and a nut are engaged, and a threaded portion of the fastening bolt may sequentially pass through the first adjustment oblong holes 2131-the lifting support 10-the first adjustment oblong holes 2131 and then engage with the nut, so that the base 21 may be mounted to the lifting support 10 by the engagement of the fastening bolt and the nut.

However, it will be understood by those skilled in the art that the number of the first adjustment oblong holes 2131 provided in the lower mounting plate 213 is not limited thereto, and that in order to further increase the coupling force between the base 21 and the lifting support 10, the number of the first adjustment oblong holes 2131 may be appropriately increased, for example, two, three, or even more pairs of the first adjustment oblong holes 2131 may be provided.

Furthermore, the first fastening member 2132 is not limited to a structure in which a fastening bolt and a nut are engaged, and any other structure that can achieve the same effect is also possible, for example: a snap-in structure, etc.

In an exemplary embodiment of the present utility model, a pair of upper mounting plates 212 may be disposed at an upper surface of the base plate 211 with a space therebetween, a first end of the first pipe member 22 may be disposed between the pair of upper mounting plates 212, the pair of upper mounting plates 212 may be provided with a horizontally extending second adjustment oblong hole 2121 facing each other, and a second fastening member 2122 may pass through the second adjustment oblong hole 2121 and the first end of the first pipe member 22 to mount the first pipe member 22 to the base 21.

In the illustrated example, the pair of upper mounting plates 212 are provided with two pairs of horizontally extending second adjustment oblong holes 2121 facing each other, and the second fastening member 2122 may be a structure in which a fastening bolt and a nut are engaged, and a threaded portion of the fastening bolt may sequentially pass through the second adjustment oblong holes 2121-first ends of the first pipe member 22-the second adjustment oblong holes 2121, and then engage with the nut, so that the first pipe member 22 may be mounted to the base 21 by the engagement of the fastening bolt and the nut.

The number of the second adjustment oblong holes 2121 provided in the pair of upper mounting plates 212 is not limited thereto, and any number of the second adjustment oblong holes 2121 may be provided according to practical applications, for example, one, three, or even more pairs of the second adjustment oblong holes 2121 may be provided.

Due to the elongated shape of the first adjustment oblong hole 2131 and the second adjustment oblong hole 2121, the first fastening member 2132 and the second fastening member 2122 can be positioned at any position in the length direction of the first adjustment oblong hole 2131 and the second adjustment oblong hole 2121, whereby the relative positions between the foundation 21 and the lifting support 10, and between the first pipe fitting 22 and the foundation 21 can be adjusted to be suitable for different counterweight structures.

The first tube member 22 and the second tube member 23 are tubular members extending in the vertical direction, and may have square, circular, prismatic, triangular, or the like cross-sectional shapes. In an exemplary embodiment of the present utility model, the first pipe member 22 and the second pipe member 23 may have square cross-sectional shapes, and chamfers may be formed between both sides adjacent in the circumferential direction.

According to the exemplary embodiment of the present utility model, the jacking mechanism 2 may include two pipe members, but the present utility model is not intended to limit the number of pipe members to two, the number thereof may be set to one, three, four, five, etc., and the length and cross-sectional shape of each pipe member may be variously changed to meet different use demands.

Here, the number of the pipe elements in the jacking mechanism 2 may be arbitrarily set, for example, in the case where the machine-room-less car is topped, when the floor height of the bottom beam in the counterweight structure is small, only one pipe element may be applied; in the case of a larger ground clearance of the bottom beam in the counterweight structure, two or more tubes can be used, thus meeting the needs of different counterweight structures.

Preferably, the lifting mechanism 2 may comprise two tubes, so that it is possible to meet the need for a vast majority of counterweights, and to avoid the problem of too long a single tube.

A first end of the first tube member 22 may be mounted to the base 21 and a first end of the second tube member 23 may be connected to a second end of the first tube member 22.

Referring to fig. 5 in conjunction, the first end of the first tube member 22 is provided with a perforation through which the aforementioned second fastening member 2122 may pass.

When the flat portion 241 of the support 24 is in contact with the bottom beam of the counterweight structure of the elevator, the distance of the limit bolt 244 protruding from the second curved portion 243 is adjusted so that the bottom beam can be locked in place.

In this case, when the counterweight structure is lifted by the elevator rescue device, the counterweight structure can be stably lifted, and rescue work can be safely and reliably performed.

In addition, due to the construction of the limit bolt 244 in the support 24 of the present utility model, even when the specification of the bottom beam of the counterweight structure of the elevator is changed, the bottom beam can be stably caught and positioned by adjusting the distance of the limit bolt 244 protruding from the second curved portion 243, and thus the elevator rescue device of the present utility model can be applied to the counterweight structures of various specifications.

In an exemplary embodiment of the present utility model, the support 24 may be connected to the second end of the second pipe 23 by a bracket 245.

Preferably, the bracket 245 may include a reinforcing rib 2451, and the reinforcing rib 2451 may improve the coupling strength between the support 24 and the second pipe 23, thereby improving the support strength.
