Problems solved by technology

If the equipment runs at a constant speed, the traction force needs to be changed all the time. Since the force provided by the current traction system is constant, it cannot meet our requirements for force changes.

Embodiment 1

[0014] The gourd string type counterweight device used on curved track running equipment consists of: a top counterweight 1 connected to the traction system, the top counterweight is connected to the counterweight wheel 2, and the connected counterweight wheel passes through Connecting chain 3 connects next group of counterweight wheels 4.

Embodiment 2

[0016] In the gourd string type counterweight device used on curved track running equipment described in Embodiment 1, there are light rail rollers 5 on the outside of the connecting chain of the counterweight wheels, and the number of the counterweight wheels is 3-50.

[0017] Open and close the stadium with the roof, such as image 3 As shown, the movable roof 6 keeps running at a constant speed on the main truss curved track 7 as an example for illustration. In order to realize uniform speed operation, we can adopt constant traction system 8 (such as hoist, hoist has certain rated power, and the traction force provided is approximately constant force) to be used in conjunction with device 9 of the present invention, and the weight of counterweight wheel and the length of connecting chain are designed according to the operation requirements , the weight wheels are connected by connecting chains. The weight of the movable roof counterweight device changes with the number of ...

Abstract

The invention relates to an irregular borehole-type counter weight device for operating equipment of a curved track. At present, most of common counter weight systems are counter weight blocks with bigger volume, occupy big space and have inflexible application, and counter weight is not changed in the operating process of the equipment, and therefore, the demand on force change can not be satisfied. The irregular borehole-type counter weight device comprises a top end counter weight connected with a traction system; the top end counter weight is connected with a connecting counter weight wheel (2), and the connecting counter weight wheel is connected with a set of counter weight wheels (4) by a connecting chain (3). The irregular borehole-type counter weight device is used for the counter weight which needs force change on the operating equipment of the curved track.

Description

Technical field: [0001] The invention relates to a gourd string type counterweight device used on curved track running equipment. Background technique: [0002] At present, most of the common counterweight systems are large counterweights, which take up a lot of space and are not flexible in application. The counterweight does not change during the operation of the equipment. In some roof opening and closing stadium projects, the movable roof is required to run at a constant speed on the curved truss track beam. The movable roof runs on a curved track. First, the traction force needs to overcome the component force of the equipment's own weight along the direction of the track. Since the track is curved, the angle between the direction of gravity and the tangent of the curve changes, so the force of the self-weight along the direction of the track changes. of. If the equipment runs at a constant speed, the traction force needs to be changed all the time. Since the force pr...
