Description
Technical field
This utility model belongs to derrick crane technical field, is specifically related to a kind of device for dismounting balance weight on counter-jib.
Background technology
The installing/dismounting of derrick crane balance weight is completed by truck crane when derrick crane installs or removes initial antenna height.After tower crane raises, when need to dismantle balance weight because of cause specific, the lifting altitude of truck crane is inadequate, must set up mast-up on counter-jib temporarily, relies on the lifting mechanism of tower crane self to realize.Mast-up is generally gathered materials on the spot, and with scaffold tube and fastener association, will be dropped after this hoisting bracket gathered materials on the spot, it is impossible to recycling, causes the waste of manpower and materials；And lack of standardization owing to setting up temporarily so that the poor stability of supporting structure, leave Hoisting Security hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of derrick crane balance weight Dismountable device, physical dimension standard, and quick and easy for installation, reliable and stable, security performance is high, it is possible to recycling.
For achieving the above object, this utility model be the technical scheme is that a kind of derrick crane balance weight assembling and disassembling device voluntarily, including hoist rope, tower top angle pulley, lifting mechanism and suspension hook, also include the framework being detachably connected on tower crane counter-jib；Described frame roof is provided with the hoisting beam parallel with counter-jib axis；Some pin-and-holes it are provided with along its length on described hoisting beam；Described hoisting beam is equipped with leading block, and described leading block positions on the length direction of hoisting beam by inserting the pulley spindle in pin-and-hole；Described hoist rope one end is wound on the reel of lifting mechanism, after its other end passes around the pulley in tower top angle pulley, leading block and suspension hook successively, then is fixed in the pin-and-hole on hoisting beam by fag end steady pin.
Preferably, described framework includes four root posts, and described adjacent upright posts upper end is connected by upper frame crossbeam and longeron high-strength bolt, and adjacent upright posts lower end is then not attached to, and forms the detachable frame structure of extremity semi-open type；Described column lower end is equipped with otic placode, and described tower crane balance arm main limb back segment is provided with four corresponding with otic placode position ear plate base, passes through high strength exploitation between described otic placode and ear plate base
This utility model has the advantages that the some pin-and-holes on hoisting beam make lifting hook pulley, the fag end position of hoist rope can regulate, thus change the position of suspension hook, makes suspension hook can be located at and treats above the balance weight of handling；Framework from as bolt connect detachable structure, easy to assembly fast；Framework and counter-jib are for removably connecting, it is achieved that recycling.Can utilize the hoist rope of tower crane self, lifting mechanism and tower top angle pulley that balance weight is carried out handling, it is possible to cost-effective, simplify structure.

Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of derrick crane balance weight assembling and disassembling device voluntarily, including hoist rope 12, tower top angle pulley 11, lifting mechanism 13 and suspension hook 7, also include the framework being detachably connected on tower crane counter-jib；Described frame roof is provided with the hoisting beam 3 parallel with tower crane counter-jib axis；Length direction along hoisting beam 3 is provided with some pin-and-holes；Being equipped with leading block 4 in the pin-and-hole of described hoisting beam 3, described leading block 4 positions on the length direction of hoisting beam 3 by inserting the pulley spindle 5 in pin-and-hole；Described hoist rope 12 one end is wound on lifting mechanism 13, after its other end passes around the pulley in tower top angle pulley 11, leading block 4 and suspension hook 7 successively, then is fixed in the pin-and-hole on hoisting beam 3 by fag end steady pin 6.Described hoisting beam 3 is double limb channel-section steels, and it opens grade spacing can accommodate leading block 4；Spacing between described adjacent pin-and-hole, equal to the spacing of adjacent flat weight 14, ensures that hoist rope 12 can be through hoisting beam 3 on lifting hook pulley simultaneously；Pin-and-hole on hoisting beam makes leading block, the fag end position of hoist rope 12 can regulate, thus change the position of suspension hook 7, spacing between described adjacent pin-and-hole is equal to the spacing of hanger on adjacent flat weight 14, the position adjustments making suspension hook 7 is convenient, and location more accurately makes suspension hook can be located at and treats the surface of hanger in the balance weight 14 of handling.
Preferably, described framework includes four root posts 8, described adjacent upright posts 8 upper end is connected with high-strength bolt by upper frame crossbeam 1 and longeron 2, adjacent upright posts 8 lower end is then not attached to, form the detachable frame structure of extremity semi-open type, owing to balance weight 14 both sides are shelved on balance arm main limb by bearing pin, extremity semi-open type frame structure is avoided that and this bearing pin generation location conflicts, makes framework can be arranged on smoothly on balance arm main limb；Described column 8 lower end is equipped with otic placode, described tower crane balance arm main limb back segment is provided with four corresponding with otic placode position ear plate base, by high strength exploitation between described otic placode and ear plate base, high strength exploitation is for removably connecting, it is achieved the recycling of framework.
Preferably, also include that the hound 10 for support frame, described hound 10 two ends are equipped with otic placode；Described tower crane counter-jib is provided with the body transom 9 of band ear plate base；Described upper frame crossbeam 1 is provided with ear plate base；The otic placode at described hound 10 two ends is connected with the ear plate base on upper frame crossbeam 1 and body transom 9 respectively by high-strength bolt.Hound can improve the stability of framework, prevents frame deformation, improves security performance.
The using method of this device is described as a example by the balance weight 14 of dismounting counter-jib outermost end, and step is as follows:
Tower top angle pulley 11 walked around by step one, hoist rope 12, after pulley in leading block 4, suspension hook 7, hoist rope 12 is fixed by the pin-and-hole that fag end steady pin 6 inserts hoisting beam 3 outermost end, and pulley spindle 5 is inserted in the pin-and-hole of a pin-and-hole with interval, now suspension hook 7 is positioned at the underface of middle pin-and-hole, the namely surface of the hanger of balance weight 14.
Hoist rope 12 released by step 2, lifting mechanism 13, and suspension hook 7 hooks the hanger of balance weight 14, tightens up hoist rope 12, and balance weight 14 is lifted up about 50mm, extracts the assembling bearing pin between balance weight 14 and balance arm main limb out.
Hoist rope 12 released by step 3, lifting mechanism 13 makes suspension hook 7 decline, and puts balance weight 14 to ground.
Step 4, fag end steady pin 6 and pulley spindle 5 are moved in the most adjacent pin-and-hole, carry out handling according to above-mentioned steps, by that analogy, until all balance weights of handling 14.
