Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Such as figure 2 , image 3 with Figure 4 As shown, a vertical moving device for an elevator includes several rollers pivotally mounted on the frame 1 of the elevator and guide rails 3 installed vertically. The guide rail 3 adopts aluminum profiles to be formed at one time, and a steel belt 4 is laid on the guide surface where the guide rail 3 cooperates with the rollers, and the rollers and the steel belt 4 are in rolling contact.
[0029] The above-mentioned guide rail 3 includes a first column 31 and a second column 32 which are spaced apart, and each of the first column 31 and the second column 32 is provided with at least three guide surfaces which cooperate with the rollers.
[0030] The above-mentioned first column 31 is provided with three guide surfaces, respectively the first guide surface 311, the second guide s...

The invention relates to a vertical movement device of an elevator, comprising a plurality of rollers pivoted on a rack of the elevator and a guide rail which is vertically arranged, wherein the rollers and the guide rail form a guide rail pair, so that the elevator can vertically elevates along the direction of the guide rail. The vertical movement device is characterized in that the guide rail is formed by using an aluminum profile at one step; a steel strip is laid on guide surfaces where on which the guide rail is matched with the rollers; and the rollers are in rolling contact with the steel strip. According to the vertical movement device, the guide rail is formed by stretching the aluminum profile at one step so as to be high in precision and strength; the quenched steel strip is embedded on the aluminum profile, the characteristic of wear resistance of the steel strip is utilized, and meanwhile, the high precision of the aluminum profile is sufficiently utilized; and the aluminum profile is formed by being stretched at one step, and therefore, the precisions of all the guide surfaces and mutual position precisions are sufficiently ensured.
Description
technical field [0001] The invention relates to a vertical moving device of an elevator. Background technique [0002] Existing lift vertical movement devices such as figure 1 As shown, the guide rail a1 is a hollow or solid rectangular or square tube with four guide surfaces a2 in rolling contact with the rollers. Each guide surface a2 on a3 is equipped with a screw a4 parallel to the guide surface a2. The four screws a4 are connected by nuts a5 and four support plates a6 to form a circle around the guide rail a1. Each screw a4 passes through The bearing a8 is pivotally mounted with a roller a7 that is in rolling contact with the corresponding guide surface a2. [0003] The vertical moving devices of these two elevators have the following disadvantages: 1) The precision requirements of the rectangular guide rail are high, the processing is difficult, and the surface is not wear-resistant; 2) The frame moves unstable and shakes greatly during the movement; 3) The assembly ...
