Description
Technical field
This utility model relates to a kind of elevator expansion tightening wheel device, a kind of expansion tightening wheel device for express elevator.
Background technology
When elevator is at top layer, steel wire rope is just in counterweight-side, and counterweight-side, with regard to many weight of steel wire rope, along with the continuous up and down motion of elevator, can produce dynamic imbalance, and when elevator is at bottom, steel wire rope is just in cage side, and cage side is with regard to many weight of steel wire rope.It is usually on elevator and is equipped with compensated chain for compensating the weight of steel wire rope, make elevator even running.Fill compensated chain and just can balance drop when elevator moves up and down.
The kind of compensated chain the most on the market is a lot, when using them for express elevator, is typically chosen use and compensates steel wire rope, owing to the speed of service of express elevator is higher, there will be shake severity, cause rock of car, noise big, make passenger's ride experience the problem such as have a greatly reduced quality.
Utility model content
The purpose of this utility model is, it is provided that a kind of express elevator expansion tightening wheel device.It may be used for the tensioner compensating steel wire rope of express elevator, such that it is able to improve compensation steel wire rope stationarity in running process of elevator, eliminate safe hidden trouble, and then improves runnability and the security performance of elevator, reaches quiet comfortable effect.
The technical solution of the utility model: a kind of express elevator expansion tightening wheel device, it is characterized in: include that base, base are provided with two vertical guide rails, linked together by leading truck above guide rail, article two, being provided with swelling device between guide rail, swelling device is internally installed expansion tightening wheel；Swelling device be provided with touch ferrum and under touch ferrum, guide rail is provided with anti-TRIP and broken step chain device, and anti-TRIP is positioned at the top touching ferrum, and broken step chain device touches the lower section of ferrum under being positioned at.
In above-mentioned express elevator expansion tightening wheel device, described swelling device by lead boots and under lead boots and be fastened in guide rail.
In aforesaid express elevator expansion tightening wheel device, described guide rail connecting and has connecting rod, small end is connected with guide rail by rotational pin, and in the connection of connecting rod lower end has the wedge track that roller, roller are plugged in anti-jump seat, described anti-jump seat is fixed on swelling device.
In aforesaid express elevator expansion tightening wheel device, described under lead boots side and be provided with support spring, well buffering can be played, be conducive to improving the comfort of car.
Compared with prior art, this utility model is by carrying out tensioner by a swelling device being arranged in guide rail to compensating steel wire rope, the potential safety hazard drastically increase and compensate steel wire rope stationarity in running process of elevator, eliminating conventional compensation device, thus improve runnability and the security performance of elevator, reach quiet comfortable effect.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present utility model；
Fig. 2 is scheme of installation of the present utility model.
Being labeled as in accompanying drawing: 1-base, 2-guide rail, 3-leading truck, 4-swelling device, 5-expansion tightening wheel, 6-touches and under ferrum, 7-, touches ferrum, the anti-TRIP of 8-, 9-broken step chain device, 10-leads and under boots, 11-, leads boots, 12-connecting rod, the anti-jump seat of 13-.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings, but is not intended as the foundation that this utility model is limited.
Embodiment.A kind of express elevator expansion tightening wheel device, as shown in Figure 1: include that base 1(and well pit are fixed), base 1 is provided with two vertical guide rails 2, is linked together by leading truck 3 above guide rail 2, article two, being provided with swelling device 4 between guide rail 2, swelling device 4 is internally installed expansion tightening wheel 5；Swelling device 4 be provided with touch ferrum 6 and under touch ferrum 7, guide rail 2 is provided with anti-TRIP 8 and broken step chain device 9, and anti-TRIP 8 is positioned at the top touching ferrum 6, and broken step chain device 9 touches the lower section of ferrum 7 under being positioned at.Described swelling device 4 by lead boots 10 and under lead boots 11 and be fastened in guide rail 2.Connecting on described guide rail 2 and have connecting rod 12, connecting rod 12 upper end is connected with guide rail 2 by rotational pin, and in the connection of connecting rod 12 lower end has the wedge track that roller, roller are plugged in anti-jump seat 13, described anti-jump seat 13 is fixed on swelling device 4.Lead boots 11 side under described and be provided with support spring.
Operation principle of the present utility model: during use, is connected fixing with the bottom of counterweight for the one end compensating steel wire rope, and the other end is connected, the most as shown in Figure 2 by fixing with the bottom of car after the expansion tightening wheel of express elevator expansion tightening wheel device of the present utility model.Owing to swelling device itself has certain quality, can play tensioner and the guide effect compensating steel wire rope.
The guide rail of swelling device, on lead boots, under lead the boots composition guiding up and down to swelling device, and for swelling device left and right side force present in cage operation process, under lead boots and be designed to side spring cupport structure, play well buffering, be conducive to improving the comfort of car.
There is the most small displacement in swelling device in car normal course of operation; but should control in certain limit; cause swelling device position out of control under car is at damage; shift up down certain distance and get to anti-TRIP; prevent car from continuing to run with cut-out elevator power supply, and the Anti-tripping structure (being made up of above-mentioned anti-jump seat, connecting rod etc.) being mechanically designed with self-locking each other realizes duplicate protection.
After car uses a period of time, compensate steel wire rope and can there is particularly evident in a certain degree of extension, particularly high-rise building or extreme case (wire cable rupture), therefore the device of utility model is provided with breaking rope protecting switch, it is achieved effective electic protection.
