In the multiple arrangement structure of the heavy-load high-speed guide shoe, as an optimal choice, a protective cover plate is arranged at the top of the guide shoe support, the guide chute is arranged in the protective cover plate, and the area of the protective cover plate is larger than the horizontal plane area required by the installation of the side guide wheel and the positive guide wheel.
In the multiple arrangement structure of the heavy-duty high-speed guide shoes, preferably, safety tongs are arranged between the guide shoe sets at the upper end and the lower end of the vertical beam.
According to the technical scheme, the main bearing components of the car frame, such as the vertical beam, the upper beam and the like, are fully utilized, and the double guide shoes at the upper end of the car frame are arranged on different bearing components in a limited space, so that the stress correlation between the two guide shoes is dispersed. The first guide shoe of one of them acts directly on the vertical beam, while the second guide shoe is supported by the upper beam, so that the strength requirement for each guide shoe mounting is greatly reduced. The first guide shoe and the second guide shoe are identical in structural design, the working intervals corresponding to the guide rails of the elevator are the upper part and the lower part of the same guide rail section (the same point position for the whole set of elevator), the tightness of the two guide shoes is kept, and the elevator car is completely restrained from moving along the guide rails under the condition that the technical requirements of unbalance loading and vibration concentration required by heavy load and high speed are met.
This scheme remains unchanged to conventional sedan-chair frame rack structure, can not increase the shared space of sedan-chair frame in the well during practical application, the upper beam adopts double list roof beam structure, under the prerequisite that satisfies the heavy load requirement, design an arch support frame, stride across first guide shoe and form a supporter at first guide shoe top, two feet are fixed a position respectively just on two list roof beams, make the second guide shoe all dissolve by the upper beam, as long as leave empty elevator guide rail's current space on arch support frame can. Meanwhile, the requirement of the installation space of the roller guide shoe is met, the roller guide shoe consisting of the pair of side guide wheels and the positive guide wheel occupies a slightly larger installation space relative to other guide shoe structures, and the design of the arched support frame ensures that the independent leveling process of the guide shoe is not influenced mutually.
Compared with the prior art, the beneficial effects of the utility model are that: the stress correlation between the two guide shoes on the upper part of the car frame is dispersed, the structural strength requirement of the guide shoe mounting seat is greatly reduced, a good operation space is provided for independently leveling the guide shoes, the stress deformation risk of the guide shoes is reduced, the running effect of the elevator is ensured, the influence of the service quality of the elevator caused by loading unbalance loading is eliminated, and the service life of the elevator is prolonged.
