Abstract

The utility model discloses a counter-weight-free speed limiter tension device for an elevator. The counter-weight-free speed limiter tension device for the elevator comprises a support which has a shape like a Chinese character 'Ji', a cross-shaped support and a limiter rope sheave; the support which has the shape like a Chinese character 'Ji' is connected with the cross-shaped support through an adjusting bolt; the limiter rope sheave is arranged on the cross-shaped support; and a compression spring is arranged in the support which has the shape like a Chinese character 'Ji' and is sleeved on the adjusting bolt and is fixed by an adjusting nut. Tension is provided by the compression spring, and counter weight is eliminated, so the volume and weight of the limiter tension device are reduced greatly, cost is saved, and the limiter tension device is convenient to transport and install.

Description

The non-counterweight elevator over-speed governor tensioning apparatus
Technical field
The utility model relates to a kind of elevator over-speed governor tensioning apparatus, particularly a kind of non-counterweight elevator over-speed governor tensioning apparatus.
Background technology
For guaranteeing the safe in operation of elevator, when the speed of lift car decline surpasses setting value, must elevator be stopped, this just must set device of installation, and this device is exactly a velocity limiter.Through velocity limiter, mechanically detect the descending speed of car, when the car descending speed surpasses setting value, make the brake equipment control elevator emergency brake of car, car is stopped.
Traditional elevator over-speed governor tensioning apparatus (as shown in Figure 1) all needs the high density movement weight mass to come enough tension force to speed limiter wire rope to be provided, and more than 15kg, movement weight mass weight accounts for most of weight of whole tightening device to movement weight mass usually; Usually adopt high density materials such as cast iron or steel plate because of movement weight mass, relative cost is higher; Because of the existence of movement weight mass, the tightening device volume and weight is bigger in addition, is not easy to transportation and installation.
The utility model content
The technical matters that the utility model will solve is: traditional elevator over-speed governor tensioning apparatus provides tension force by clump weight thereby volume and weight is big, cost is higher relatively, be not easy to problems such as transportation and installation in order to overcome, and a kind of non-counterweight elevator over-speed governor tensioning apparatus is provided.
The utility model solves the technical scheme that its technical matters adopted: a kind of non-counterweight elevator over-speed governor tensioning apparatus; Comprise " several " shape support, " ten " font support and governor sheave; " several " shape support passes through to regulate bolted connection with " ten " font support; Governor sheave is installed on " ten " font support, in " several " shape support compression spring is installed, and compression spring is through to regulate on the bolt and by setting nut and fixes.
The beneficial effect of the utility model is: adopt compression spring that tension force is provided, cancelled counterweight, the volume and weight of over-speed governor tensioning apparatus is reduced greatly, and practice thrift cost, be convenient to transportation and installation.
Description of drawings
Fig. 1 is the front view of prior art elevator over-speed governor tensioning apparatus;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the block diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As illustrated in fig. 1 and 2, be prior art elevator over-speed governor tensioning apparatus front view and birds-eye view, for vertical carriage 101 links to each other with lateral bracket 102; Governor sheave 104 is installed on the lateral bracket 102; Its terminal counter weight device 103 that connects, i.e. weight (piece), coming provides enough tension force to speed limiter wire rope; Usually more than 15kg, weight (piece) weight accounts for most of weight of whole tightening device to weight (piece); Because of weight (piece) adopts high density materials such as cast iron or steel plate usually, relative cost is higher, and because of the existence of weight (piece), the tightening device volume and weight is bigger in addition, is not easy to transportation and installation.
As shown in Figure 3; A kind of non-counterweight elevator over-speed governor tensioning apparatus; Comprise " several " shape support 1, " ten " font support 2 and governor sheave 3, " several " shape support 1 passes through to regulate bolted connection with " ten " font support 2, and governor sheave 3 is installed on " ten " font support 2; In " several " shape support 1 compression spring 5 is installed, compression spring 5 is through to regulate on the bolt and by setting nut 6 and fixes.
The utility model is opened device, adopts compression spring that tension force is provided, and is used for substituting traditional weight (piece), and the volume and weight of tension wheel reduces greatly, economical with materials and traffic cost; Simultaneously, the installation site is flexible, and the elevator pit space constraint that traditional relatively tightening device receives is less.
The utility model tightening device function reality:
Before tightening device is installed, setting nut 6 is torqued-up to end position, after the completion to be installed, at last setting nut 6 is unscrewed to perch, compression spring 5 provides enough power to come the tensioning speed limiter wire rope.

Claims (1)

1. non-counterweight elevator over-speed governor tensioning apparatus; It is characterized in that: comprise " several " shape support (1), " ten " font support (2) and governor sheave (3); " several " shape support (1) is connected through regulating bolt (4) with " ten " font support (2); Governor sheave (3) is installed on " ten " font support (2), and compression spring (5) is installed in " several " shape support (1), and compression spring (5) is through adjusting bolt (4) and goes up and fixed by setting nut (6).
