Abstract
The invention discloses a structure capable of mounting and dismounting a balancing weight automatically by a tower crane. The structure comprises a lifting mechanism (11), a lifting pulley (12), an automatic balancing weight device (14) and a steel wire rope (13), wherein the lifting mechanism is installed on a balance arm (16); the automatic balancing weight device (14) comprises a support (21), a first upper pulley (22) and a second upper pulley (23) which are installed on the support (21), a lower pulley (24) which is positioned below the first upper pulley (22) and the second upper pulley (23) and is connected with a balancing weight (15); the steel wire rope (13) starts from the lifting mechanism (11), sequentially bypasses the lifting pulley (12), the second upper pulley (23), the lower pulley (24) and the first upper pulley (22), winds back and is fixed on the lifting mechanism (11). The lifting mechanism of the tower crane acts as a power source, so that the balancing weight can be stably and conveniently mounted and dismounted.
Description
Technical field
The present invention relates to the structure that a kind of tower machine peace tears counterbalanced weight open, particularly relate to a kind of tower machine from the structure installing and certainly dismantle counterbalanced weight.
Background technology
Tower machine counterbalanced weight general cylinder iron or ferro-concrete manufacture form, be placed on equilibrium arm afterbody, moment balance when keeping the work of tower machine.The Assembly &Disassembly of current tower machine, mode the most general utilizes the weight-lifting equipments such as wheel crane, slings by certain step each framing member by tower machine, and then complete assembling or the dismounting of tower machine complete machine.The handling of counterbalanced weight are also like this.
But current counterbalanced weight handling mode has some deficiency following: one is use wheel crane by the rent use outside amount paid, need increase cost.Two is in some Special complex operating mode, is difficult to recycling wheel crane to complete the handling of counterbalanced weight: such as, when fabricating yard is narrow and small, wheel crane operation inconvenience; For another example, tower machine needs to complete change arm or disintegration aloft sometimes, at this moment needs disengaging section counterbalanced weight, and now counterbalanced weight distance floor level may up to more than 200m, and in this case, wheel crane is limited to arm stroke, has been difficult to the lifting of counterbalanced weight.
Therefore, urgently design the tower machine that a kind of more traditional counterbalanced weight handling mode is more economic, operation is also novel more flexibly certainly install and certainly dismantle counterbalanced weight version.
Summary of the invention
For above-mentioned existing technical matters, the invention provides a kind of tower machine from the structure installing and certainly dismantle counterbalanced weight, to have more economy and alerting ability.
For achieving the above object, the invention provides a kind of tower machine from the structure installing and certainly dismantle counterbalanced weight, comprise the lifting mechanism be arranged on equilibrium arm, be arranged on the lifting pulley of tower top, what be arranged on equilibrium arm outer end hangs counter weight device and steel rope certainly; The described counter weight device that certainly hangs comprises and the support certainly hanging counter weight device and be fixedly connected with, the first rack-mount top sheave and the second top sheave, and the lower sheave being positioned at both belows, and lower sheave detouchable connects counterbalanced weight; Described steel rope, from lifting mechanism, successively through lifting pulley, the second top sheave, lower sheave, the first top sheave wraparound be fixed on lifting mechanism, so, can realize utilizing jack up unit risen by assembly pulley pulsation-free or put down counterbalanced weight.
Further, described lower sheave is connected with counterbalanced weight detouchable by bearing pin.
Further, the tail end of described steel rope is fixed on the cover of wedge of lifting mechanism.
The present invention utilizes the lifting mechanism of tower machine self as propulsion source, coordinates with a set of handling weight-balancing device be arranged on equilibrium arm, when counterbalanced weight not being sling by when outside weight-lifting equipment, and then realize tower machine counterbalanced weight to install and from dismounting.This technical scheme has following advantage:
1) this apparatus structure is simple, with low cost, can replace extra hanging device completely, realizes certainly installing and from dismounting, decreasing cost of equipment, reduce costs of counterbalanced weight, improves operating efficiency, have more economy;
2) this device flexible operation, under efficiently solving Special complex operating mode, counterbalanced weight installs or removes difficult problem, is suitable for more extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is from the structural representation hanging counter weight device in Fig. 1;
Fig. 3 is the left view of Fig. 2;
In figure: 11, lifting mechanism, 12, lifting pulley, 13, steel rope, 14, certainly hang counter weight device, 15, counterbalanced weight, 16, equilibrium arm, 21, support, the 22, first top sheave, the 23, second top sheave, 24, lower sheave.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention includes the lifting mechanism 11 be arranged on equilibrium arm 16, be arranged on the lifting pulley 12 of tower top, be arranged on certainly hanging counter weight device 14, being lifted on from hanging counterbalanced weight 15 below counter weight device 1 and steel rope 13 of equilibrium arm 16 outer end.
As shown in Figures 2 and 3, be fixed on equilibrium arm 16 by support 21 from hanging counter weight device 14.It comprises and the support 21 certainly hanging counter weight device 14 and be fixedly connected with, and installs the first top sheave 22 and the second top sheave 23 on the stent 21, and is positioned at the lower sheave 24 of both belows, and lower sheave 24 is by bearing pin lifting counterbalanced weight 15.
As shown in figures 1 and 3, steel rope 13 sets out from lifting mechanism 11, successively on lifting pulley 12, second top sheave 23, lower sheave 24, first top sheave 22 wraparound lifting mechanism 11.
When counterbalanced weight 15 is installed, first counterbalanced weight 15 is placed in below equilibrium arm 16, by steel rope 13 by lifting mechanism 11, successively through lifting pulley 12, second top sheave 23, lower sheave 24, first top sheave 22, wraparound lifting mechanism 11 goes out, and is fixed on the cover of wedge of lifting mechanism 11 by steel rope 13 tail end.Then, utilize lifting mechanism 11 to put down lower sheave 24, with bearing pin, it is connected with counterbalanced weight 15.Again counterbalanced weight 15 is risen to level attitude, installation personnel guides on equilibrium arm 16, is fixed on counterweight support by counterbalanced weight 15.Then, install according to same each the block counterweight of lifting of preceding method.
During dismounting counterbalanced weight 15, identical when steel rope 13 baudrier and installation counterbalanced weight 15.With bearing pin, lower sheave 24 is connected with counterbalanced weight 15, utilizes lifting mechanism 11 slowly to put down lower sheave 24 and connected counterbalanced weight 15, until counterbalanced weight 15 steadily lands.
The lifting mechanism 11 of employing tower machine self like this, as propulsion source, is acted on by the weight-balancing device 14 that certainly hangs on equilibrium arm 16, just can complete certainly installing and dismounting certainly of counterbalanced weight 15.
