Embodiment Construction
[0036] Below in conjunction with accompanying drawing, the roller guide shoe of the present invention is described in detail.
[0037] Such as figure 1 , figure 2 As shown, a roller guide shoe includes: a base 11, three rollers 8 installed on the base 11 to enclose a guide rail running channel, and guide rail clamping pieces that cooperate with each other are provided on both sides of the guide rail running channel.
[0038] Roller 8 adopts the roller of conventional roller guide shoe, and the material of the direct contact part of roller 8 outer ring and guide rail is polymer material such as rubber or plastics, and the installation structure of roller 8 is the same as conventional roller guide shoe.
[0039] Each side guide rail clamping part comprises: the fixed wedge 6 that is installed on the base 11, the movable wedge 7 that is slidably installed on the fixed wedge 6, and drives the movable wedge 7 to move relative to the fixed wedge 6 to clamp or Release the drive me...

Abstract
The invention discloses a roller guide shoe. The roller guide shoe comprises a base and three rollers which are arranged on the base and define a guide rail running channel in a surrounding mode, guide rail clamping pieces matched with each other are arranged on the two sides of the guide rail running channel, the guide rail clamping piece on each side comprises a fixed wedge block arranged on thebase, a movable wedge block arranged on the corresponding fixed wedge block in a sliding mode and a driving mechanism which drives the corresponding movable wedge block to move relative to the corresponding fixed wedge block so as to clamp or release the guide rail, and each movable wedge block is provided with a clamping surface matched with a guide rail and a sliding surface which is obliquelyarranged relative to the corresponding clamping surface and is in contact with the corresponding fixed wedge block. According to the provided roller guide shoe, the frictional resistance is small, thevibration reduction effect is good, the noise is low, the operation is comfortable, and the safety is higher.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a roller guide shoe. Background technique [0002] At present, roller guide shoes are mainly used in high-speed elevators or elevators with high requirements for comfort. Roller guide shoes have the advantages of small frictional resistance, good vibration damping effect, and low noise, but they also have some disadvantages. For example, the outer ring of the roller is usually made of flexible materials such as rubber. When the elevator stops running for a period of time, the roller will deform. When the deformed roller starts, it will cause the elevator to vibrate, thereby affecting the comfort of the elevator; In addition, the rollers generally adopt an elastic fixing method, and the gap between the guide shoes will become larger after the force is applied. When passengers enter and exit the elevator or carry goods, the elevator will tilt. If the inclination is too large, i...
