Description
1, technical field
The present invention relates to the big improvement selling mounting or dismounting technology, i.e. tower crane big pin hydraulic pressure tool for fastening/disengaging and technical scheme in the work of a kind of tower crane climbing.
2, technical background
Existing various tower crane climbing system structure principle is the most similar, all by the Hydraulic Station and being arranged on being arranged on tower crane climbing joint platform climb the hydraulic lifting cylinder between joint with basic joint, ratchet, claw trace etc. form (Such as figure 1Shown in).Its operation principle of climbing is: exit eight pins climbed on joint and four angles of basic joint, here it is the big pin that people are generally commonly called as, when hydraulic lifting cylinder will climb joint slowly push up certain altitude upward time, climb and have a space between joint and basic joint, now tower crane pair hooks and ground mark joint handling is come and send into the little Crane Rail above the joint that climbs, it is fed into by little driving and climbs in joint abdomen, declined by hydraulic lifting cylinder and adjust below standard knot eight pin-and-holes above eight pin-and-holes and basic joint and progressively overlap, and by eight big pins successively press-in pin-and-holes (Figure 1、Figure 2), make the standard knot of feeding and basic joint be linked to be an entirety, load onto interlocking plunger (Figure 1、Figure 2In 6), plug split pin (Figure 1、Figure 2In 7), by this one even, the standard knot of feeding has reformed into basic joint, and now, the work of climbing of mark joint terminates substantially, prepares next joint and climbs work, so goes round and begins again.
nullClimbing in work of each joint，The big pin of dress is the most time-consuming laborious work，Pin greatly is the most once pounded into pin-and-hole with sledgehammer by this work at present by workman，The big pin of mounting or dismounting is the most difficult，Being because tower crane is the vertical handling appliance of superelevation，Cantilevered radius is the biggest，Intensity and the precision of connecting pin to tower body、Stiffness requires the highest，Pin and hole are interference fit，The tightest，So a pin often to be pounded tens times and just can put in place，And a tower crane generally uses the most all more than hundred meters，Average mark joint length about 2.5 meters，Will 40 feast-brand mark joints with 100 meters of calculations，Often joint wants eight pins，40 joints just have 320 pins，Every pin pounds 40 hammers，Total to be pounded and to be hammered 10,000 more，For the platform narrow and small in superaltitude is done this work，This is highly intensive labour how and high-risk action，Therefore，Generally this difficult point place in work of namely climbing，Visible，The meaning inventing this tower crane big pin hydraulic pressure tool for fastening/disengaging is extraordinary.
3, purpose is with advanced
3.1 purpose of the present invention: substitute present artificial sledgehammer with a kind of tower crane big pin hydraulic pressure tool for fastening/disengaging and the most once pound the mounting and dismounting method of big pin.
The advance of 3.2 present invention: 1) lean on the continuous action power of hydraulic pump output to have quiet, efficient, eliminate the noise that conventional sledgehammer is pounded out, improve environmental pollution index；2) change the process that conventional able-bodied labour manually swings the big pin of mounting or dismounting of sledgehammer, significantly reduce labor intensity, improve efficiency, saved labour force；3) improve efficiency due to hydraulic pressure dress pin, the time-to-climb of shortening, the most just decrease production suspension induced losses, relatively add economic benefit.
The progressive meaning of 3.3 present invention: 1) tower crane big pin hydraulic pressure tool for fastening/disengaging will not destroy big pin end flat and the face of cylinder, and extend and sell service life greatly, also ensure that precision and intensity；2) owing to changing mounting and dismounting method, improve work high above the ground work situation, improve the safety coefficient of work high above the ground；3) improve efficiency, overall economic efficiency is notable.
4, summary of the invention
Exported by the fluid power of device hydraulic power unit on tower crane climbing body panel, drive custom-designed Portable hydraulic pump in a playscript with stage directions invention (Figure 3) reciprocating motion of the pistons, when on portable hydraulic pump two claws rectify with tower body frame angle steel row become closing to rectify time, the thrust that reciprocating motion of the pistons produces is in big pin tail end plane, make to sell greatly and under the promotion of active force, enter tower body rectify the pin-and-hole of frame angle steel, it is achieved thereby that the conception of mounting or dismounting big pin hydrofication during tower crane climbing.
When this tower crane big pin hydraulic pressure tool for fastening/disengaging and technical scheme overcome tradition tower crane climbing, the big pin of mounting or dismounting pounds, by manpower sledgehammer, all drawbacks brought into the method pounded out, without the need for increasing additional corollary equipment, tower crane first wife's Hydraulic Station improves, specifically slightly: 1) increase by a pair fluid power output interface to portable hydraulic pump use；2) increase by one operation handle with control portable hydraulic pump (Figure 3、Figure 4)；3) by increase fluid power output interface high-pressure hose and portable hydraulic pump (Figure 3、Figure 4) connect, and by the joystick conversion and control increased, easy to operate laborsaving.
5, the substantive distinguishing features of this tower crane big pin hydraulic pressure tool for fastening/disengaging and progressive meaning
5.1 features: this tower crane big pin hydraulic pressure tool for fastening/disengaging and technical scheme achieve use easily, safety, simply, swing sledgehammer by workman in the air at height time method substitutes conventional tower crane climbing efficiently and pound the overall process of pin.
5.2 progressive meanings: due to a general pin to pound tens times the most up to a hundred under, the most in particular cases can pound to enter half a day, therefore this tower crane big pin hydraulic pressure tool for fastening/disengaging thoroughly changes the hard nut to crack in tower crane climbing work, not only to tower crane climbing work create light, safe, climb result simply, efficiently, mounting or dismounting big pin efficiency can also be greatly improved, the time-to-climb of effectively shortening, eliminate negative effect produced by the psychological burden of workman, so significant economic benefit can be produced after using this tower crane big pin hydraulic pressure tool for fastening/disengaging.Once it is widely applied, social synthesis's effect in front will be produced.
6, sum up
6.1 tower cranes belong to special trade, and climbing is superaltitude operation, and the labor intensity reduction operational hazards coefficient raising safety coefficient alleviating operator is significant；
The substantially clean sound of 6.2 tower crane big pin hydraulic pressure tool for fastening/disengaging and technical scheme work process, the operation principle ratio pounded with existing sledgehammer eliminates noise, prevents noise pollution from laying a good foundation from source for protection environment.
6.3 tower crane big pin hydraulic pressure tool for fastening/disengaging and technical scheme work efficiency are high, and mounting or dismounting pin is fast, the time-to-climb of being greatly shortened, decreases idle cost, and therefore, overall economic efficiency is notable.
6.4 use tower crane original corollary equipment Hydraulic Station to improve a little, the portable hydraulic pump overall structure of Aided design is simple and reliable, existing production and technique all belong to mature technology, therefore it is low to have requirement, reduced investment, instant effect, the advantages such as scientific and technological content is high, good economic benefits and social effect will be produced.
