Abstract

The utility model discloses an integral structure of a home elevator car frame and a bracket, which comprises two straight beams (1), wherein an upper beam (2) is arranged above the space between the two straight beams (1), a collet longitudinal beam (3) is arranged on the inner side of the bottom of the straight beam (1), a collet rectangular pipe (4) is arranged between the two collet longitudinal beams (3), shock pads (5) are arranged above two ends of the collet longitudinal beam (3), and a buffer (6) is arranged below the middle part of the collet longitudinal beam (3). The utility model has the characteristic of effectively reducing the requirement of the car frame on pit space.

Description

Integrated structure of household elevator car frame and bracket
Technical Field
The utility model relates to a car frame, in particular to an integral structure of a car frame and a bracket of a household elevator.
Background
The elevator car frame is a bearing structure of the car, and the load (dead weight and load) of the car is transmitted to the traction steel wire rope through the elevator car frame. When the safety gear is actuated or the squat base impacts the buffer, the reaction force generated thereby is also borne, so that the car frame needs to have sufficient strength. The car frame generally comprises upper beam, stand, floorbar and bracket etc. be equipped with the blotter between floorbar and the bracket, and floorbar and bracket are 2 layers of arrangement structure, and overall thickness is great, and is higher to the pit depth requirement, and the pit depth of domestic well is less, generally 200mm, will reduce the car space like this. Therefore, the prior art has the problem that the car frame has higher requirement on pit space.
Disclosure of Invention
The utility model aims to provide a household elevator car frame and bracket integrated structure. The utility model has the characteristic of effectively reducing the requirement of the car frame on pit space.
The technical scheme of the utility model is as follows: the utility model provides a home use elevator sedan-chair frame and bracket integral type structure, includes two straight beams, and the top between two straight beams is equipped with the upper beam, and the inboard of straight beam bottom is equipped with the collet longeron, is equipped with the collet rectangular tube between two collet longerons, and the top at collet longeron both ends is equipped with the shock pad, and the below at collet longeron middle part is equipped with the buffer.
In the integral structure of the home elevator car frame and the bracket, guide shoe mounting grooves are respectively formed in the upper ends of the straight beams, and guide shoe openings are formed in the middle of the lower ends of the straight beams.
In the integral structure of the home elevator car frame and the bracket, the straight beam is a C-shaped piece, the lower guide shoe is arranged in the guide shoe opening, and the upper guide shoe is positioned in the guide shoe mounting groove.
In the integral structure of the home elevator car frame and the bracket, the outer side of the collet longitudinal beam is provided with the reinforcing piece connected with the straight beam.
In the integral structure of the home elevator car frame and the bracket, the collet longitudinal beam is of an L-shaped structure.
Compared with the prior art, the elevator car frame comprises a straight beam, an upper beam, a collet longitudinal beam, a collet rectangular pipe and a reinforcing piece, wherein the collet longitudinal beam is arranged at the inner side of the bottom of the straight beam, shock absorption pads are arranged above two ends of the collet longitudinal beam, and a buffer is arranged in the middle of the lower part of the collet longitudinal beam, so that the elevator car frame and the bracket are combined into a whole, the space occupation of the elevator car frame is effectively reduced on the premise of ensuring the structural strength, and the space requirement of the elevator car frame on a bottom shell can be further reduced, and the space of an elevator car is enlarged; the utility model provides a not only solved the space problem, possess shock attenuation buffer function again. In addition, the bracket and the car frame are combined into a whole, so that the production cost of the car frame can be reduced by about 25 percent. In addition, the straight beam of this application is C type spare structure, and the straight beam bottom sets up and leads the boots opening, sets up at the straight beam upper end and leads boots mounting groove for thereby can reduce the clearance between guide rail and the sedan-chair frame, further improve space utilization. In summary, the utility model has the characteristic of effectively reducing the requirement of the car frame on pit space.
