Abstract
The utility model discloses an oil cylinder system used for traction transportation in order to achieve the self traction balance of double ropes and double oil cylinders of a single hoist. The coaxial double-drum-area hoist and double-oil-cylinder connecting system comprises a hoist (5), two traction steel wire ropes (2-1 and 2-2) are led out from the hoist, and the two traction steel wire ropes are fixed to two oil cylinders(1-1 and 1-2) of a same dragged object (4). The connecting system is characterized in that the hoist (5) is provided with a spindle (5-1) which penetrates through a coiling drum (5-2), the middle of the coiling drum and the two ends of the coiling drum are respectively provided with a partition plate (5-3) so that the coiling drum is divided into two rope coiling areas, and one traction steel wire rope is fixed to each rope coiling area; two hydraulic oil cavities of the two oil cylinders are communicated through a hydraulic rubber hose (3-3).
Description
Technical field
The utility model belongs to industrial and mineral operation parts, specifically a kind of for drawing the cylinder system of transportation.
Background technology
In producing, industrial and mineral usually can use the synchronous tractive operation of two strands or multistrand rope, to keep being pulled the balance and stability of thing.In practical application, this type of tractive adopts oil cylinder more.Single cylinder force is limited, and it is flexible synchronous that two or many oil cylinder combineds action cannot guarantee again, often causes the inclination that is pulled lifting object even to be overturned, if tractive lifting is manned equipment, consequence is hardly imaginable.Chinese patent literature CN102505630A discloses a kind of pair of cylinder system, and this system applies is on bridge inspection vehicle manned long-armed, and respectively there is an oil cylinder long-armed both sides, use respectively flexible pipe UNICOM between the oil pocket of two oil cylinders and oil pocket, cavity and cavity.Thus, the long-armed stressed opposite side that is greater than of any side, in the oil pocket of this side cylinder, press and increase, oil will be along with flexible pipe flows in the oil pocket of opposite side oil cylinder, air in cavity can counter-flow, until both sides are stressed consistent, realize balance, thereby guaranteed long-armedly can even not overturn because force unbalance causes distortion.Through contriver's research and test, this invention still can effectively improve.
Summary of the invention
The utility model technical issues that need to address are to realize the tractive self-balancing of the two oil cylinders of single winch duplex type.
A kind of coaxial bitubular of the present utility model district winch and two oil cylinder connected system, comprise a winch, by drawing twice haulage cable on winch, this twice haulage cable is fixed on same two oil cylinders that are pulled on thing, described winch has a main shaft, and main shaft is through reel, and respectively there is dividing plate at the centre of reel and two ends, reel is divided into Liang Ge serving district, and a haulage cable is fixed in each serving district; Between the fluid chamber of two described oil cylinders, with hydralic hose, be connected.
The utility model is improved to coaxial bitubular district, duplex type winch by traditional single rope winch.Because the bitubular is coaxial, so the lifting-speed of its twice steel rope of drawing is Complete Synchronization.The utility model has adopted again two oil cylinder balanced systems, between two oil cylinders, with hydralic hose, is communicated with fluid chamber each other.When the elevator operation of longer stroke, the coiling of twice steel rope inevitably there will be difference, causes a small amount of overbalance.The cylinder force of piston rod stroke length is large, and according to pascal's principle, hydraulic oil herein will flow in the short oil cylinder of piston rod stroke, has also transmitted pressure simultaneously.In order to simplify pipeline, raise the efficiency, the utility model has been cancelled the cavity of background technology and the flexible pipe between cavity.
As preferably, between the fluid chamber of two described oil cylinders and hydralic hose, be provided with two-way valve.If two-way valve has been created condition for the artificial single oil cylinder of intervention of getting involved, in real world applications, can tackle some specific condition and environment.
The described thing that is pulled is inclined shaft dolly, can make the utility model performance optimal effectiveness.
The utlity model has simple in structurely, reasonable in design, realized the balance tractive of the two oil cylinders of single winch duplex type.As long as condition license, design of the present utility model can also extend to single winch Multi-cylinder balanced system of restricting more, or even many winchs Multi-cylinder balanced system of restricting more.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below by embodiment also by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1, sees Fig. 1.This example is for being applied to coaxial bitubular district winch and the two oil cylinder connected systems on the travelling bogie of inclined shaft operation, 5 is a winch, being pulled thing 4 is a travelling bogie running on track, this car is travelled to and fro between well head and underground work point, be responsible for conveying people and material, must guarantee safety and the balance of vehicle operating.Two oil cylinder 1-1 and 1-2 that same model same specification is installed on travelling bogie 4, the piston rod 1-1-1 of oil cylinder is connected with aboveground winch 5 with 2-2 with steel rope 2-1 respectively with 1-2-1; This winch 5 has a main shaft 5-1, and main shaft is through reel 5-2, and respectively there is dividing plate 5-3 at the centre of reel and two ends, and reel is divided into Liang Ge serving district, and a haulage cable is fixed in each serving district; Between the fluid chamber of two oil cylinders, with hydralic hose 3, connect.
Embodiment 2, see Fig. 1.Between the fluid chamber of this routine oil cylinder and hydralic hose, be provided with two-way valve 3-1 and 3-2, in normally open, all the other are with example 1.Close two-way valve, can adapt to the operating mode that single oil cylinder such as was overhauled, and upgraded, changes oil at the needs human intervention.
Claims (3)
1. a coaxial bitubular district winch and two oil cylinder connected systems, comprise a winch (5), by drawing twice haulage cable (2-1,2-2) on winch, this twice haulage cable is fixed on same two oil cylinders (1-1,1-2) that are pulled on thing (4), it is characterized in that: described winch (5) has a main shaft (5-1), main shaft is through reel (5-2), respectively there is dividing plate (5-3) at the centre of reel and two ends, reel is divided into Liang Ge serving district, and a haulage cable is fixed in each serving district; Between the fluid chamber of two described oil cylinders, with hydralic hose (3-3), be connected.
2. a kind of coaxial bitubular according to claim 1 district winch and two oil cylinder connected system, is characterized in that: between the fluid chamber of two described oil cylinders and hydralic hose, be provided with two-way valve (3-1,3-2).
