[0083] in, Figure 2 The right side view in Figure 2 The enlarged schematic diagram of the A part in the left view in FIG. 1 is shown in FIG. 1 , and in order to more clearly illustrate the structure of the A part, Figure 2 The right side view in Figure 2 The left view in the figure is rotated at an angle.

[0084] In order to clearly illustrate the structure of the first reinforcing plate mounting assembly and the relationship between the first reinforcing plate mounting assembly and the first reinforcing plate, Figure 5 The base in the figure has one upper mounting plate removed.

[0085] The elevator rescue device of the present invention acts on the counterweight structure of the elevator. Generally, the elevator includes a car, a counterweight guide rail, and a counterweight structure, etc. The counterweight structure of the elevator may include a counterweight block and a counterweight frame, and the counterweight frame may include a bottom beam, etc. A plurality of counterweight blocks are placed on the bottom beam in a stacked manner, and the counterweight guide rail includes a first side guide rail and a second side guide rail facing each other, and the first side guide rail and the second side guide rail are respectively arranged on both sides of the counterweight structure, and when the elevator is running, the counterweight structure can move along the first side guide rail and the second side guide rail.

[0086] Reference Figures 1 to 5 The elevator rescue device of the present invention may include a lifting mechanism 1 and a jacking mechanism 2, wherein the lifting mechanism 1 is provided with a lifting support 10 capable of moving in the vertical direction. In one embodiment of the present invention, the lifting mechanism 1 may be a jack mechanism called a monkey climbing bar, and the lifting support 10 may be a component in the monkey climbing bar mechanism that can move along the bar, and when the handle in the monkey climbing bar mechanism is pressed, the lifting support 10 may move vertically along the bar.

[0087] Since the jack mechanism is a known structure in the prior art, it will not be described in detail herein to avoid unnecessarily obscuring the gist of the present invention.

[0088] However, those skilled in the art should understand that the lifting mechanism 1 of the present invention is not limited to the monkey climbing pole mechanism (jack mechanism), and any other mechanism that can achieve the same effect is also acceptable, such as: a lifting mechanism using a manual or electric screw, a hydraulic lifting mechanism, etc.

[0089] The lower end of the jacking mechanism 2 is detachably mounted to the lifting support 10 of the lifting mechanism 1 so as to be able to move in the vertical direction as the lifting support 10 moves. The upper end of the jacking mechanism 2 can contact the bottom beam (not shown) of the counterweight structure of the elevator to support the counterweight structure of the elevator, so that the counterweight structure of the elevator can move upward by the upward movement of the jacking mechanism. In this way, in the case of a machine room-less car hitting the top, when there are trapped people on the top of the car and the emergency electric button of the elevator control box fails, rescue work can be carried out through the elevator rescue device.

[0090] Mate Reference Figure 2 The jacking mechanism 2 according to the exemplary embodiment of the present invention may include a base 21 , a first pipe member 22 , a second pipe member 23 , and a support member 24 .

[0091] The base 21 is located at the lower end of the lifting mechanism 2 , and the base 21 is detachably mounted to the lifting support 10 .

[0092] Mate Reference Figure 3The base 21 may be formed by a plurality of plate-shaped elements being joined to each other. More specifically, the base 21 may include a base plate 211 , an upper mounting plate 212 , and a lower mounting plate 213 .

[0093] In an exemplary embodiment of the present invention, the number of the upper mounting plates 212 may be set to a pair, and the lower mounting plate 213 may be formed in an n-shape, wherein a pair of upper mounting plates 212 may be provided on the upper surface of the base plate 211, and the n-shaped lower mounting plate 213 may be provided on the lower surface of the base plate 211. At least a pair of first adjustment oblong holes 2131 extending horizontally facing each other may be provided in the lower mounting plate 213, and the first fastening member 2132 may pass through the first adjustment oblong holes 2131 and the lifting support 10 to mount the base 21 to the lifting support 10.

[0094] Correspondingly, a base mounting hole (not shown) is provided in the lifting support 10 , and the first fastening member 2132 can pass through the first adjustment oblong hole 2131 - the base mounting hole - the first adjustment oblong hole 2131 in sequence, thereby mounting the base 21 to the lifting support 10 .

[0095] In the example shown, 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 can be a structure in which a fastening bolt and a nut cooperate. The threaded portion of the fastening bolt can pass through the first adjustment oblong hole 2131-lifting support 10-first adjustment oblong hole 2131 in sequence, and then engage with the nut, so that the base 21 can be installed to the lifting support 10 through the cooperation of the fastening bolt and the nut.

[0096] However, those skilled in the art should understand that the number of the first adjustment oblong holes 2131 provided in the lower mounting plate 213 is not limited thereto. In order to further improve the bonding force between the base 21 and the lifting support 10, the number of the first adjustment oblong holes 2131 can be appropriately increased. For example, two pairs, three pairs, or even more pairs of first adjustment oblong holes 2131 can be provided.

[0097] In addition, the first fastening member 2132 is not limited to a structure composed of a fastening bolt and a nut, and any other structure that can achieve the same effect is also acceptable, such as a snap-fit ​​structure.

[0098] In an exemplary embodiment of the present invention, a pair of upper mounting plates 212 can be arranged on the upper surface of the base plate 211 at intervals from each other, the first end of the first pipe fitting 22 can be arranged between the pair of upper mounting plates 212, and the pair of upper mounting plates 212 are provided with second adjustment oblong holes 2121 extending horizontally facing each other, and the second fastening member 2122 can pass through the second adjustment oblong holes 2121 and the first end of the first pipe fitting 22 to mount the first pipe fitting 22 to the base 21.

[0099] In the example shown, a 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 can be a structure in which a fastening bolt and a nut cooperate. The threaded portion of the fastening bolt can sequentially pass through the second adjustment oblong hole 2121-the first end of the first pipe fitting 22-the second adjustment oblong hole 2121, and then engage with the nut, so that the first pipe fitting 22 can be installed to the base 21 by cooperating with the fastening bolt and the nut.

[0100] The number of the second adjustment oblong holes 2121 set in a pair of upper mounting plates 212 is not limited thereto, and any number of second adjustment oblong holes 2121 can be set according to actual application conditions. For example, one pair, three pairs, or even more pairs of second adjustment oblong holes 2121 can be set.

[0101] Due to the slender shape of the first adjusting oblong hole 2131 and the second adjusting 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 adjusting oblong hole 2131 and the second adjusting oblong hole 2121, so the relative position between the base 21 and the lifting support 10, and between the first pipe 22 and the base 21 can be adjusted to adapt to different counterweight structures.

[0102] The first pipe member 22 and the second pipe member 23 are tubular elements extending in the vertical direction, and may have a square, circular, prismatic, triangular, etc. cross-sectional shape. In an exemplary embodiment of the present invention, the first pipe member 22 and the second pipe member 23 may have a square cross-sectional shape, and a chamfer may be formed between two adjacent side surfaces in the circumferential direction.

[0103] According to an exemplary embodiment of the present invention, the lifting mechanism 2 may include two pipe fittings, but the present invention is not intended to limit the number of pipe fittings to two. The number may also be set to one, three, four, five, etc., and the length and cross-sectional shape of each pipe fitting may also be varied to meet different usage requirements.

[0104] Here, the number of pipe fittings in the lifting mechanism 2 can be set arbitrarily. For example, in the case of a machine room-less car top, when the height of the bottom beam in the counterweight structure from the ground is relatively small, only one pipe fitting can be used; and when the height of the bottom beam in the counterweight structure from the ground is relatively large, two or more pipe fittings can be used to meet the needs of different counterweight structures.

[0105] Preferably, the lifting mechanism 2 may include two pipes, which can meet the needs of most counterweight structures and avoid the problem of a single pipe being too long.

[0106] A first end of the first pipe member 22 may be mounted to the base 21 , and a first end of the second pipe member 23 may be connected to a second end of the first pipe member 22 .

[0107] See also Figure 5 The first end of the first pipe 22 is provided with a through hole, and the aforementioned second fastening member 2122 can pass through the through hole.

[0108] The support member 24 is located at the upper end of the lifting mechanism 2 and connected to the second end of the second pipe member 23. The support member 24 is configured to contact the bottom beam of the counterweight structure of the elevator.

[0109] The support member 24 is a U-shaped member, which may be formed by joining a plurality of plate members to each other, or may be formed by extruding and bending a single member.

[0110] The support member 24 may include: a flat portion 241 , a first curved portion 242 , a second curved portion 243 and a limiting bolt 244 , wherein the first curved portion 242 and the second curved portion 243 protrude from the flat portion 241 in a direction away from the second pipe member 23 , and the limiting bolt 244 may be disposed on the second curved portion 243 .

[0111] When the flat portion 241 of the support member 24 contacts the bottom beam of the counterweight structure of the elevator, the distance of the limiting bolt 244 protruding from the second curved portion 243 is adjusted so that the bottom beam can be clamped and positioned.

[0112] In this case, when the counterweight structure is lifted by the elevator rescue device of the present invention, the counterweight structure can be raised smoothly, thereby allowing the rescue work to be carried out safely and reliably.

[0113] In addition, due to the structure of the limiting bolt 244 in the support 24 of the present invention, even when the specifications of the bottom beam of the counterweight structure of the elevator change, the bottom beam can be stably clamped in place by adjusting the distance that the limiting bolt 244 protrudes from the second curved portion 243. Therefore, the elevator rescue device of the present invention can be applicable to counterweight structures of various specifications.

[0114] In an exemplary embodiment of the present invention, the support member 24 may be connected to the second end of the second pipe member 23 by a bracket 245 .

[0115] Preferably, the bracket 245 may include a reinforcing rib 2451, and the reinforcing rib 2451 may improve the joining strength between the support member 24 and the second pipe member 23, thereby improving the supporting strength.

[0116] The connection method between the support member 24 and the second pipe member 23 is not limited thereto.

[0117] In another embodiment of the present invention, the flat portion 241 of the support member 24 can form a joining flange (not shown), which can protrude from the flat portion 241 toward the second pipe fitting 23, and the joining flange can at least partially surround the outer peripheral surface of the second end of the second pipe fitting 23 and contact the outer peripheral surface of the second end of the second pipe fitting 23, and a joining element (such as a joining bolt) can pass through the joining flange and the second end of the second pipe fitting 23 to connect the support member 24 and the second pipe fitting 23.

[0118] Furthermore, the lifting mechanism 2 may include: a guide assembly 25 , a connecting member 26 and a reinforcing member 27 .

[0119] In the illustrated example, the guide assembly 25 is disposed between the second pipe 23 and a counterweight guide rail (not shown), and the guide assembly 25 is configured to guide the movement of the jacking mechanism 2 .

[0120] In another embodiment of the present invention, the guide assembly 25 may be disposed between the first pipe 22 and the counterweight guide rail (not shown).

[0121] In yet another embodiment of the present invention, guide assemblies may be provided simultaneously between the first pipe member 22 and the counterweight guide rail, and between the second pipe member 23 and the counterweight guide rail.

[0122] According to an exemplary embodiment of the present invention, the guide assembly 25 may include: a first guide member 251 and a second guide member 252, the first end of the first guide member 251 may be connected to the first side surface of the second pipe member 23, the second end of the first guide member 251 may be provided with a guide groove, and the guide groove of the first guide member may clamp the first side guide rail in the counterweight guide rail.

[0123] In an exemplary embodiment of the present invention, the guide groove is provided in the form of an opening.

[0124] More specifically, the second end of the first guide member 251 may be bent downward, and may be provided with an opening 2511 that extends through the bent portion and extends a distance toward the first end of the first guide member 251. The first side guide rail in the counterweight guide rail may be inserted into the opening 2511 of the first guide member 251, and the bent portion may abut against the bottom surface of the counterweight guide rail, so that the first guide member 251 may move along the counterweight guide rail and be guided by the counterweight guide rail.

[0125] In particular, the portion of the bent portion of the first guide member 251 that contacts the bottom surface of the counterweight guide rail can be surface treated so that excessive friction is not generated when contacting the bottom surface of the guide rail, thereby avoiding affecting the service life of the counterweight guide rail and the guide member.

[0126] The first end of the second guide member 252 can be connected to the second side surface of the second tube member 23 opposite to the first side surface, and the second end of the second guide member 252 can be provided with a guide groove, and the guide groove of the second guide member can clamp the second side guide rail in the counterweight guide rail, and the first side guide rail and the second side guide rail face each other.

[0127] In an exemplary embodiment of the present invention, the guide groove is provided in the form of an opening.

[0128] More specifically, the second end of the second guide member 252 may be bent downward and may be provided with an opening 2521 extending through the bent portion and extending a distance toward the first end of the second guide member 252. The second side guide in the counterweight guide rail may be inserted into the opening 2521 of the second guide member 252, and the bent portion may abut against the bottom surface of the counterweight guide rail, so that the second guide member 252 may move along the counterweight guide rail and be guided by the counterweight guide rail, wherein the first side guide and the second side guide face each other.

[0129] Similarly, the portion of the bent portion of the second guide member 252 that contacts the bottom surface of the counterweight guide rail can be surface treated so that excessive friction is not generated when contacting the bottom surface of the guide rail, so as to avoid affecting the service life of the counterweight guide rail and the guide member.
