Abstract

The utility model provides a tower crane with the base following the storey rising whose tower body is formed by an external sleeve rack and an internal sleeve rack which is arranged in the external sleeve rack and can slide along the external sleeve rack from top to bottom. The base of the crane is connected with the tower body with screws and detachable. While the utility model is in use, the base can be arranged on the floor of each storey, and can hoist the crane following storey rising. The utility model has the advantages of no occupation in installation, steel saving in fabrication and reduced manufacturing cost.

Description

Tower crane with base following storey rising

The utility model belongs to machinery for building.

Existing tower crane for building generally all is mounted in and supplies construction usefulness near the vacant lot of building, and this does not often have this vacant lot for some in narrow location or overlooking building available.In addition, these tower cranes are owing to be located on the ground, the body of the tower height must be higher than the height of building, and present Urban House all develops to high level, so body of the tower requires very high, it is big to make used steel consumption, causes hoisting crane price height, and general medium and small construction team purchases difficulty.

The purpose of this utility model is transformed existing tower crane, makes on its floor that can directly be placed in the construction residential building, and can jump along with the rising of floor, thereby the body of the tower manufacturing of hoisting crane is highly shortened, saved steel consumption, reduce cost, and do not account for the place, convenient construction.

Main points of the present utility model are that the body of the tower of tower crane is made two parts, and a part is outer stock, the interior stock of another part for placing in the outer stock, also can sliding up and down along outer stock.Base is totally two covers, forms by two crossbeams with stull and strut beam that bolt is attached thereto respectively, and the crossbeam of base is connected with outer stock usage is blue, strut beam and interior stock bolt together, and the two is all detachable.For promoting interior stock, the bottom of two side top that stock is relative and corresponding two sides of interior stock and bottom surface central authorities install pulley (totally 14) respectively outside, constitute the assembly pulley that jumps, on this assembly pulley around steel cable, one end of steel cable is fixed on the top of outer stock, and the other end is connected on the winch that is positioned at the cover top of the trellis.For stock in reducing promotes resistance, stock inside is equipped with roller respectively in place, eight end angles up and down outside.For alleviating lifting weight, outer stock can be made four rectangle frames fans of separation, and bolt together is assembled into integral body, and interior stock is made segment type up and down, and at four angles place's welding triangle flange of the contact surface of every joint, bolt together is integral.

Below in conjunction with accompanying drawing structure of the present utility model and using method are described in detail.

The structure of utility model is with reference to Fig. 1-6

Fig. 1 is its integral structure assembling scheme drawing, and wherein 1 is base, and 2 is outer stock, and 3 is interior stock, and 4 is crane arm, 5 is equilibrium arm, and 6 is last rotating disc, and 7 are the load-carrying dolly, and 8 is the tower cap, 9 is winch, and 10 is operator's compartment, and 11 is that outer stock supports, and 12 are the assembly pulley that jumps.

Fig. 2 is its understructure assembling scheme drawing, and wherein 13 is crossbeam, and 14 are stull, and 15 is strut beam, and 16 is that outer stock connects screw, and 17 is that interior stock connects screw, and 18 are the support and connection screw.

Fig. 3 is the attached view of overcoat top of the trellis, and wherein 19 for being positioned at the pulley of overcoat top of the trellis, and 20 is roller, and 11 is to support, and this is connected with bolt (21) with outer stock on supporting, and 22 for being welded on the flange of locating at four base angles (for being connected with the base crossbeam).

Fig. 4 is interior stock (bottom surface) upward view, and wherein 23 is interior stock pulley, and 24 are and base strut beam bonded assembly screw.

Fig. 5 respectively saves the contact surface view for interior stock, and wherein 25 is the triangle flange.

Fig. 6 for the assembly pulley steel cable string that jumps around scheme drawing, two row (totally 5) circle expressions of figure middle and upper part are positioned at the pulley of overcoat top of the trellis, three row (totally 9) circle expressions of bottom are positioned at the pulley of stock bottom, the attachment point of steel cable is positioned at the overcoat top of the trellis, and the other end (shown in the arrow) connects winch.

Fig. 7 is a base scheme of installation of the present utility model, when two floor plates (26) install, when building a wall (27) by laying bricks or stones, reserve to give and box out, treat that a wall builds, the base crossbeam is inserted this hole, and at crossbeam and give cushioning plank (28) between making sheet, beam-end usefulness steel plate (29) and timber wedge (30) plug are solid, after base installs and fixes, promptly by orders such as interior stock, outer stock, operator's compartment, last rotating disc, tower cap, crane arm, equilibrium arm, load-carrying dollies hoisting crane are assembled.When engineering enters when the 3rd floor plate is installed, the making sheet (two) of giving in the place that crane tower was worn is given the spy stubble that stays by a wall earlier and is built the hole and be placed between the neighbour on the floor, treats again it to be moved into vacant locations after hoisting crane jumps, and puzzles and visit a stubble brick hole.

Fig. 8 is the scheme drawing that jumps of this hoisting crane, when lifting highly need improve, when finishing as laying when the 4th floor plate, on the floor at the 4th floor body of the tower place of passing, install earlier the crossbeam and stull (identical) of the second cover base with aforementioned foundation mounting method, then outer stock is pulled down from the first cover base, hang four floors, and be installed on the crossbeam of the second cover base, then string winds the steel cable (by shown in Figure 6) of the pulley that jumps, with the load-carrying dolly, mass on the equilibrium arm moves to tower cap place, again interior stock and strut beam attachment bolt are unloaded, start the winch that connects the pulley steel cable, interior stock connection slowly can be risen to the 4th buildings with full machine, insert the second cover strut beam then, and good with crossbeam and interior stock with bolt, promptly to finish one and jump the cycle, lifting highly improves two floors.

The utility model is pressed 16 tons/meter of hoisting moments, 2 tons of the biggest lifting capacities, 16 meters of work ranges, 80 meters designs of the highest hoisting depth, the base crossbeam is with the poor steel of 18-20#, stull is with the poor steel of 12#, strut beam 16# I-beam section, outer stock column 75 angle steel, stull 70 angle steel, diagonal brace 60 angle steel, high 2.4 meters, 1.25 meters are square, interior stock column 60 angle steel, stull 50 angle steel, diagonal brace 40 angle steel divide 5 meters from bottom to up, 2.5 rice, 2.5 rice three joints, remaining part all adopts the typing universal component, full machine is conducted oneself with dignity about about 5 tons, and every of the QT60/80 type fixed base tower crane of more existing use is saved steel more than 30 tons, and cost reduces more than 100,000 yuan, and install and use and do not account for the place, per two floors jump once, use very conveniently, are specially adapted to narrow area and overlooking residential construction.
