Abstract
The utility model discloses a coal transporting trestle steel truss hoist device in power plant's chimney has solved in the chimney difficult problem of hoisting the steel truss of the rectangular bodily form to chimney upper portion. Including chimney (1), in fixed be provided with upper portion ring beam (2) in the top of chimney (1), the fixed groined type hydraulic jack support frame (3) that is provided with on upper portion ring beam (2), be provided with four hydraulic jack (4) on groined type hydraulic jack support frame (3), subaerial be provided with truss (7) in chimney (1), be provided with four chain block (8) on truss (7), hydraulic jack (4) link together through jack ground tackle (5) and the one end that promotes steel strand wires (6), the other end that promotes steel strand wires (6) links together with chain block (8). The occuping of place, saved hoist and mount time is shortened, the operating expenses has been practiced thrift.
Description
Technical field
The utility model relates to a kind of hanging apparatus, particularly a kind of hanging apparatus carrying out defeated coal strage road trussed steel beam and install in power plant chimney.
Background technology
Thermal powerplant coal handling system coal transporting trestle have span greatly, highly high feature, difficulty of construction is large, security risk is high.In the construction in power plant, in order to reduce the floor area of the coal transporting trestle of coal handling system, the defeated coal strage road of some power plant is designed to the form of intersecting with chimney, in the installation of the trussed steel beam in defeated coal strage road, need to carry out in chimney, because chimney is tapered, in chimney, the trussed steel beam of cuboid is lifted into chimney top and has difficulties, on-the-spot urgent need wants a kind of device that obliquely trussed steel beam can be lifted into chimney top.
Summary of the invention
The utility model provides coal transporting trestle trussed steel beam hanging apparatus in a kind of chimney of electric plant, solves the technical barrier trussed steel beam of cuboid being lifted into chimney top in chimney.
The utility model solves above technical matters by the following technical programs:
Coal transporting trestle trussed steel beam hanging apparatus in a kind of chimney of electric plant, comprise chimney, top ring beam is fixedly installed at the top of chimney, top ring beam is fixedly installed groined type hydraulic jack bracing frame, groined type hydraulic jack bracing frame is provided with four hydraulic jacks, ground in chimney is provided with truss, truss is provided with four chain blocks, hydraulic jack is linked together by jack ground tackle and the one end promoting steel strand, and the other end and the chain block that promote steel strand link together.
It is evenly lay that four hydraulic jacks withstand on groined type hydraulic jack bracing frame.
The utility model make use of steel inner cylinder hydraulic lifting apparatus in the chimney in chimney construction to carry out trussed steel beam lifting, and carry out the assembled of trussed steel beam in chimney inside, decreases taking of place, save the lifting time, saved executive cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
Coal transporting trestle trussed steel beam hanging apparatus in a kind of chimney of electric plant, comprise chimney 1, top ring beam 2 is fixedly installed at the top of chimney 1, top ring beam 2 is fixedly installed groined type hydraulic jack bracing frame 3, groined type hydraulic jack bracing frame 3 is provided with four hydraulic jacks 4, ground in chimney 1 is provided with truss 7, truss 7 is provided with four chain blocks 8, hydraulic jack 4 is linked together by jack ground tackle 5 and the one end promoting steel strand 6, and the other end and the chain block 8 that promote steel strand 6 link together.
Four hydraulic jacks 4 are evenly lay on groined type hydraulic jack bracing frame 3.
Apply bolt between hydraulic jack 4 of the present utility model and groined type hydraulic jack bracing frame 3 to fix, jack top guide frame is fixed and settles guide piece.Lifting uses chimney Promotion From Within steel inner cylinder hydraulic jack 4 used and promotes steel strand 6, utilize 4 the great tonnage hydraulic jacks be arranged on chimney, lifting end steel strand lock through mast-up ground tackle, and 4 mast-ups and hanger are arranged in lifting end trussed steel beam top.Mast-up and hanger are that the suspension ring of employing 15 tons are connected.After every root steel strand pretension is completed, the intermediate plate of guide anchor is tightened, prevents steel strand from coming off, until whole bundle steel strand pretension is complete, and jack is adjusted to lifting state.Through calculating, design determines the reinforcing detail drawing of the size of suspension centre, position and rod member, then on coal transporting trestle, installs suspension centre.Because coal transporting trestle trussed steel beam and horizontal direction hold 16 ° of angles, west side hoisting height 18.172 meters, east side hoisting height 23.252 meters, also bracket is provided with at the both sides At The Height of chimney 1, bracket is crossed for allowing truss 7, so maximum angle 40 degree of angles are taked in lifting, thing adjustment of displacement must be carried out by artificial chain block in both sides, avoids truss to encounter bracket.When truss is lifted beyond bracket, angular adjustment is returned 20 degree, two ends are again with manually carrying out displacement location, and jack carries out transferring program.
Claims (2)
1. coal transporting trestle trussed steel beam hanging apparatus in a chimney of electric plant, comprise chimney (1), top ring beam (2) is fixedly installed at the top of chimney (1), it is characterized in that, top ring beam (2) is fixedly installed groined type hydraulic jack bracing frame (3), groined type hydraulic jack bracing frame (3) is provided with four hydraulic jacks (4), ground in chimney (1) is provided with truss (7), truss (7) is provided with four chain blocks (8), hydraulic jack (4) is linked together by jack ground tackle (5) and the one end promoting steel strand (6), the other end and the chain block (8) that promote steel strand (6) link together.
