Problems solved by technology

However, the use of an independent counterweight wheel suspension device will increase the installation height of the counterweight device, resulting in the compression of the installation space of the counterweight. It is necessary to increase the weight of the counterweight in a limited space, which will increase the price of the counterweight.
Moreover, the counterweights on the market are often stuck in the straight beam, and the space on both sides of the straight beam is not used, and the space utilization rate is low
[0004] Therefore, the counterweight device in the existing machine-room-less passenger elevator has the problems of large space occupation, high cost, complicated processing and installation

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0028] Example.

[0029] Such as figure 1 As shown, the economical counterweight device includes a counterweight frame 1 and a counterweight 2. The counterweight frame 1 includes a pair of symmetrical straight beams 21, and the straight beams 21 are in the shape of a C with the notch 43 facing outward. The straight beams The gap 43 of 21 is provided with guide shoe 6. Such as Figure 2-3 As shown, the guide shoe 6 includes a U-shaped shoe body 61 and a shoe lining 62, the two ends of the shoe body 61 extend outwards to connect with the straight beam 21, and the bottom sides of the shoe lining 62 are provided with curved edges with the shoe body 61. The slot 63 corresponds to the folding portion, and the boot lining 62 is connected to the boot body 61 through the slot 63 so as to cover the surface...

Abstract

The invention discloses an economical counterweight device. The economical counterweight device comprises a counterweight housing (1) and a counterweight assembly (2), wherein the counterweight housing (1) comprises a pair of symmetrical straight beams (21); a pair of bent upper beam plates (22) are arranged at the upper ends of the two straight beams (21); a counterweight wheel (23) is arranged between the two upper beam plates (22); a pair of symmetrical inverted-L-shaped lower beam plates (24) are arranged at the lower ends of the two straight beams (21); the tops of the lower beam plates (24) are bent outwards; the counterweight assembly (2) comprises a plurality of groups of first counterweight blocks (3) and second counterweight blocks (4) which are arranged in an up-and-down stacking manner and embedded with one another; a first notch (31) embedded with the corresponding straight beam (21) is formed in one side of each first counterweight block (3); and a second notch (41) embedded with the corresponding straight beam (21) is formed in one side of each second counterweight block (4). The economical counterweight device is characterized by being compact in structure, low in cost and convenient to install and maintain.

Description

technical field [0001] The invention relates to a machine roomless passenger motor, in particular to an economical counterweight device for a machine roomless passenger elevator. Background technique [0002] In the prior art, the components constituting the counterweight frame in the machine-room-less passenger elevator are independent of each other, have a single function, and are complicated to process and install; The actual use area is reduced, the requirements for installation conditions and hoistway space are also higher, and the applicable area is narrower; [0003] And machine-room-less passenger elevators generally install the traction machine by picking out the bracket from the side wall of the hoistway, and the counterweight wheels often need to turn at a certain angle, so an independent counterwheel suspension device needs to be connected to the counterweight frame. However, the use of an independent counterweight wheel suspension device will increase the insta...
