Description

Two oil cylinders center hydraulic jacking device
Technical field
The utility model relates to a kind of jacking that is used for tower crane and adds regulating device.
Background technology
The kind model of China's tower crane is a lot of at present, and the climbing structure form of tower machine all is to adopt outer stock jacking apparatus mostly.Jacking adds the outside that the outer stock of saving is enclosed in standard knot, and skin also needs jacking and adds the platform of saving, and makes its occupation space bigger like this, and the stock volume is big, and used steel product cost is also corresponding higher.And along with the continuing to increase of tower machine model, the structure of stock is manufactured more and more difficult also with increasing.Outer stock jacking apparatus, oil cylinder only are located at a side usually, are squinted in the center of jacking, and be unfavorable for the jacking balance of tower machine.Thereby, research and develop a kind of later-model jacking apparatus, the force position when making the jacking of tower machine is positioned at the center; And the steel structure of jacking apparatus is positioned at the body of the tower inboard; It is little to take up room, and the steel structure volume is also less relatively, and cost reduces relatively; Manufacture also more conveniently, the research and development of this jacking apparatus design will more can adapt to the demand of tower crane development.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of steel structure volume little, and save space is easily manufactured, lower-cost pair of oil cylinder center of materials hydraulic jacking device.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: two oil cylinders center hydraulic jacking device; Comprise Nei Tajie, hydraulic power unit and jacking cylinder, it is characterized in that: described jacking cylinder is 2, is positioned at the body of the tower center; Be connected through otic placode with the upper and lower rood beam of Nei Tajie respectively; The upper and lower rood beam that hydraulic power unit control jacking cylinder drives Nei Tajie is climbed piece jacking step by step along outer body of the tower standard knot, and passes through clamp, clamp lock bolt, clamp jam nut the upper and lower rood beam of Nei Tajie is connected with outer body of the tower standard knot, add section end after; The connection otic placode of Nei Tajie bottom is locked through bolt is secondary with following rood beam, and Nei Tajie is fastenedly connected through the free bearing on three hole adapter plates, bearing pin and the outer body of the tower standard knot.
The beneficial effect of the utility model: the utility model adopts said structure, the center jacking when realizing the tower crane lifting supernumerary segment, and the jacking balance performance is good.The steel structure volume is little, reduces the production difficulty, saves production cost.It is the newtype that the jacking of a kind of tower machine adds regulating device.

Among the figure: 1-Nei Tajie, 2-hydraulic power unit, 3-three hole adapter plates, 4-free bearing, 5-clamp, 6-three orifice plates are connected with free bearing with rood beam, 12-clamp lock bolt, 13-clamp jam nut, 14-under bearing pin, the last rood beam of 7-, the outer body of the tower standard knot of 8-, 9-jacking cylinder, 10-bolt pair, the 11-climbs piece, 15-three hole adapter plates and Nei Ta and saves bearing pin.
The specific embodiment
Two oil cylinders center hydraulic jacking device, tower joint 1, hydraulic power unit 2 and 9, two jacking cylinders 9 of two jacking cylinders are positioned at the body of the tower center in comprising, are connected through otic placode with the upper and lower rood beam of interior tower joint 17,11 respectively.
When entering adds outer body of the tower standard knot state, as shown in Figure 4.At first be connected fastening with clamp lock bolt 12 and clamp jam nut 13 between the outer body of the tower standard knot 8 upper and lower rood beam 7,11; To go up rood beam 7 tops then; Four the three hole adapter plates on three hole adapter plates, 3 tops of tower joint 1 and outer body of the tower standard knot 8 are connected with free bearing and save bearing pin 15 with bearing pin 6 and four three hole adapter plates and Nei Ta and dismantle in connecting; With the bottom is axle, three hole adapter plates 3 is gone to Nei Tajienei, referring to Fig. 6.Get the attachment pegs of the free bearing 4 on the outer body of the tower standard knot, propose free bearing 4, put to the tower machine platform, this moment, the tower machine got into the supernumerary segment state, and two outer body of the tower standard knots 8 adopt tenon fourth of the twelve Earthly Branches connection mode, connect through connecting pin, and are as shown in Figure 5.
The tower machine begins to get into jacking state (part of first trim jacking cylinder jack-up) after adding an outer body of the tower standard knot:
1. dismantling, it is secondary 10 to connect down rood beam 11 and eight bolts of interior body of the tower 1 bottom, and the loosening clamp jam nut 13 of going up rood beam 7 makes clamp 5 be in loosening state; (5 of actual clamps climb on the piece 14 moving; Clamp 6 is removable when the jacking of operation hydraulic power unit), operation hydraulic power unit 2 jack-up is a little gone up rood beam 7, clamp 5 is left climb piece 14; After coming to a complete stop, pull down clamp lock bolt 12 again.Eight clamps 5 are gone in the rood beam 7, referring to Fig. 7.Again operate tower joint 1 in hydraulic power unit 2 jack-up; Make the clamp 5 rising 1.5m on the rood beam 7 climb piece 14 positions to the higher level, after coming to a complete stop, eight clamps 5 are gone to just climbing piece 14 tops folder; First-class clamp lock bolt 12 is also tightened with clamp jam nut 13, and is as shown in Figure 6.
2. dismantle the down clamp fastening bolt 12 of rood beam 11 clamps 5; After operation hydraulic power unit 2 will descend rood beam 11 to mention a little; Eight clamps 5 are changed over to down in the rood beam 11, will descend rood beam 11 to carry again and climb piece 14, produce eight clamps 5 again to climbing on the piece 14 to upper class; Set up clamp fastening bolt 12, referring to Fig. 7.
3. above action repeats four times; Outer body of the tower standard knot of tower machine rising, as once adding a plurality of outer body of the tower standard knots, then every joint jacking is to afterbody; The tower machine is got into add outer body of the tower standard knot state; After adding section end, the free bearing 4 at first-class four outer body of the tower standard knot main chord tops goes to control position with three hole adapter plates 3 again and is connected with free bearing with three hole adapter plates respectively with free bearing 4 and saves bearing pin 15 with three hole adapter plates with Nei Ta with bearing pin 6 and be connected.
4. interior tower is saved 1 lower end and following rood beam 11 and use model to connect as the bolt secondary 10 of M42, eight pairs of clamp binding bolts 12, the clamp clamp nut 13 of last rood beam 7, time rood beam 11 are all fastening.This moment, the tower machine got into mode of operation, and is as shown in Figure 1.
