Embodiment Construction
[0029] Such as figure 1 and figure 2 Shown: a split type pre-tightening ball elevator guide shoe of the present invention is composed of: guide shoe seat 1, mounting bolt assembly 2, pre-tightening stud 3, stressed spring 4, ball 5, nylon fixing plate 6, thrust disc 7 , 8 fixing screws. The elevator guide shoe is installed and fixed by installing the bolt assembly 2.
[0030] Such as figure 2 and image 3 As shown, a split-type preloaded ball elevator guide shoe of the present invention is a split-type structure arranged symmetrically. Guide shoe seat 1, mounting bolt assembly 2, pre-tightening stud 3, force spring 4, ball 5, nylon fixing plate 6, thrust disc 7, and fixing screw 8 are symmetrically arranged in two sets, respectively arranged on two sets of guide rails 10 side.
[0031] Such as figure 1 As shown: the fixed plate is a nylon fixed plate 6, which is integrated with the guide shoe seat 1 through the set screw 8, and the ball 5 is fixed in the guide shoe, a...

The invention discloses a split type pre-tightened ball elevator guide shoe. The split type pre-tightened ball elevator guide shoe comprises a guide shoe base, and a ball matched with a guide rail is arranged on the guide shoe base; a fixed plate is arranged on the guide shoe base, and a through mounting chamber is arranged on the fixed plate; the ball is arranged in the mounting chamber in a floating manner; and a pre-tightening force adjusting part for pushing the ball to abut against the guide rail is arranged on the guide shoe base. According to the elevator guide shoe, the guide function of an elevator lift car is achieved, and meanwhile through the split structural design, the convenience of mounting and maintenance of the guide shoe is improved; through relative rolling contact between the ball and the elevator guide rail, stability and safety in the running process of the elevator are achieved; through connection integrality of the casted guide shoe base and the ball, the structural compactness and use safety and reliability of the guide shoe are met; and through rolling of the spring pre-tightened ball, stability and low-noise performance in the high-speed running are achieved.
Description
technical field [0001] The invention belongs to the technical field of elevator guide shoe design, in particular to a split-type pre-tightened ball elevator guide shoe. Background technique [0002] With the rapid development of social economy, elevators, as an important means of transportation for transporting people in the vertical direction, have been fully integrated into our lives and are closely related to our daily life. Therefore, everyone puts forward more and more strict requirements on the safety and comfort of elevator operation. [0003] At present, there are two kinds of guide shoes used in the elevator industry, one is a pure sliding guide shoe, which is simple to manufacture and low in cost. However, the disadvantages are that the friction coefficient is relatively large during the operation of the guide shoe, the service life of the guide shoe is low and frequent maintenance is required, and the later maintenance cost is relatively high. The other is the r...
