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:
The present invention relates to a kind of cucurbit string data counter weight device that is used on the curve track operational outfit.
Background technology:
At present mostly common Weighting system is the balancing weight that volume is bigger, and it is big to take up room, and uses dumbly, and counterweight is constant in the process that equipment moves.In some roofing opening-closing type stadium engineering, require movable roof on curve truss rail beam, to travel at the uniform speed.Movable roof moves on curve track, and at first tractive force need overcome the component of equipment self-weight direction along ng a path, because track is curved, the angle of gravity direction and curve tangent line changes, so the power of deadweight direction along ng a path changes.If equipment to travel at the uniform speed, requires tractive force to take and carves variation,, can't satisfy the requirement that our change power because the power that present trailer system provides is constant.
Summary of the invention:
The purpose of this invention is to provide a kind of cucurbit string data counter weight device that is used on the curve track operational outfit,, can realize our variation requirement power with the trailer system acting in conjunction through changing counterweight weight.
Above-mentioned purpose realizes through following technical scheme:
Be used for the cucurbit string data counter weight device on the curve track operational outfit, its composition comprises: the top counterweight that is connected with trailer system, and described top counterweight connects weighting distribution wheel, and described connection weighting distribution wheel connects set of weights wheel through connection chain,
The described cucurbit string data counter weight device that is used on the curve track operational outfit, the connection chain outside of described weighting distribution wheel has the light rail roller, and described weighting distribution wheel is 3-50.
Beneficial effect:
1. the present invention adopts the counterweight connected mode of cucurbit string data, through changing counterweight weight, can be implemented in the variation requirement of some occasions to power with the trailer system acting in conjunction.Solved present common Weighting system and be mostly the balancing weight that volume is bigger, it is big to take up room, and uses dumbly, and counterweight is constant problem in the process that equipment moves, and has realized the flexible variation of counterweight weight.When similar engineering equipment service requirement, can adopt counter weight device of the present invention to realize.
2. for the flexible operation of counter weight device, the light rail roller that the present invention installs in the outside of counterweight connection chain, and can the light rail track be set at above ground portion.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is front views of accompanying drawing 1.
Accompanying drawing 3 is the present invention's working state schematic representations when being applied in movable roof.
The specific embodiment:
Embodiment 1:
Be used for the cucurbit string data counter weight device on the curve track operational outfit, its composition comprises: the top counterweight 1 that is connected with trailer system, and described top counterweight connects weighting distribution wheel 2, and described connection weighting distribution wheel connects next set of weights wheel 4 through connection chain 3.
Embodiment 2:
The embodiment 1 described cucurbit string data counter weight device that is used on the curve track operational outfit, the connection chain outside of described weighting distribution wheel has light rail roller 5, and described weighting distribution wheel is 3-50.
With roofing opening-closing type stadium, as shown in Figure 3, movable roof 6 remains a constant speed on main couple curve track 7 and operates to example explanation.We can adopt constant tractive force system 8 (like hoist engine in order to realize traveling at the uniform speed; Hoist engine has certain rated power; The tractive force that provides is approximately constant force) be used with the present invention's 9 devices; According to service requirement design weighting distribution wheel weight and connection chain length, weighting distribution wheel links to each other through connection chain.The weight of movable roof counter weight device changes along with the variation of the weighting distribution wheel quantity of slinging; Thereby realize the linear change of tractive force; For the flexible operation of counter weight device, the light rail roller that we install in the outside of counterweight connection chain, and be provided with light rail track 10 at above ground portion.
