Abstract
The utility model discloses a kind of new type mining concrete wet spraying machine conveying cylinder, comprise master cylinder (1) and locating oil cylinder (6), master cylinder (1) comprises piston rod (2), master cylinder cylinder barrel (3) and main oil cylinder piston (4), and main oil cylinder piston (4) is connected with piston rod (2); Locating oil cylinder (6) comprises locating oil cylinder piston mechanism (5), locating oil cylinder cylinder barrel (8) and flange (9), and master cylinder cylinder barrel (3) is connected with locating oil cylinder cylinder barrel (8), afterbody flange (9) the Bonding pressure oil of locating oil cylinder cylinder barrel (8); Locating oil cylinder piston mechanism (5) and piston rod (2) are without being connected, the utility model is by independently making master cylinder and locating oil cylinder, the locating oil cylinder of its afterbody is a simple oil cylinder, during assembling, only master cylinder cylinder barrel need be connected with locating oil cylinder cylinder barrel, the quick-replaceable requirement of concrete sprayer concrete piston piston of conveying cylinder can not only be met, and be easy to processing, reduce cost of production.
Description
Technical field
The utility model relates to a kind of concrete sprayer parts, specifically a kind of new type mining concrete wet spraying machine conveying cylinder.
Background technique
In concrete for mines wet shotcrete technology machine equipment, concrete piston is fragile part, work certain hour just needs to change, but because during work, concrete piston is positioned at concrete cylinder, this concrete piston must be returned to easy-operating space when therefore changing, this just needs sprayer master cylinder can return certain distance.At present, common concrete conveying cylinder is that master cylinder combines with limiting piston mechanism, and namely main oil cylinder piston two ends have piston rod respectively, and when limiting piston retreats, under the effect of pressure oil, master cylinder retreats then, can realize moving back cylinder requirement.
But because in this mechanism, master cylinder two ends have piston rod respectively, what occur is the difficult processing problems of piston rod, also have impact on assembly precision and the sealability of master cylinder, causes the increase of cost of production thereupon simultaneously.
Summary of the invention
The utility model provides a kind of new type mining concrete wet spraying machine concrete conveying cylinder, and the independence realizing master cylinder and locating oil cylinder is processed, and can not only meet and move back cylinder requirement, and mechanism is simple, processing cost is low.
For achieving the above object, this new type mining concrete wet spraying machine concrete conveying cylinder comprises master cylinder and locating oil cylinder, and master cylinder comprises piston rod, master cylinder cylinder barrel and main oil cylinder piston, and main oil cylinder piston is connected with piston rod; Locating oil cylinder comprises locating oil cylinder piston mechanism, locating oil cylinder cylinder barrel and flange, and described master cylinder cylinder barrel is connected with locating oil cylinder cylinder barrel, the afterbody Flange joint pressure oil of locating oil cylinder cylinder barrel; Described locating oil cylinder piston mechanism and piston rod are without being connected.
Locating oil cylinder piston mechanism is one-piece piston bar.
Compared with existing equipment, this new type mining concrete wet spraying machine concrete conveying cylinder, by master cylinder and locating oil cylinder independently being made, making master cylinder become single-acting cylinder by existing double acting cylinder, decreasing the processing of main oil cylinder piston bar and connecting difficulty, the locating oil cylinder of its afterbody is a simple oil cylinder, during assembling, only master cylinder cylinder barrel need be connected with locating oil cylinder cylinder barrel, the quick-replaceable requirement of concrete piston can not only be met, and be easy to processing, reduce cost of production.
Accompanying drawing explanation
Fig. 1 is the structural drawing of this model utility.
In figure: 1, master cylinder, 2, piston rod, 3, master cylinder cylinder barrel, 4, main oil cylinder piston, 5, locating oil cylinder piston mechanism, 6, locating oil cylinder, 7, card key, 8, locating oil cylinder cylinder barrel, 9, flange.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, this new type mining concrete wet spraying machine concrete conveying cylinder, comprises master cylinder 1 and locating oil cylinder 6, and master cylinder 1 comprises piston rod 2, master cylinder cylinder barrel 3 and main oil cylinder piston 4, and main oil cylinder piston 4 is connected with piston rod 2; Locating oil cylinder 6 comprises locating oil cylinder piston mechanism 5, locating oil cylinder cylinder barrel 8 and flange 9, and described master cylinder cylinder barrel 3 is connected with locating oil cylinder cylinder barrel 8, the afterbody flange 9 Bonding pressure oil of locating oil cylinder cylinder barrel 8; Described locating oil cylinder piston mechanism 5 and piston rod 2 are without being connected.
Locating oil cylinder piston mechanism 5 can select modular construction and monolithic construction, preferred monolithic construction, can improve piston and the coaxial effect of piston rod, improve the working life of equipment.
During work, pressure oil enters the hydraulic fluid port of the afterbody flange 9 of locating oil cylinder 6, enter locating oil cylinder 6 back cavity, card key 7 place integrated type locating oil cylinder piston mechanism 5 being pushed into left position is spacing, now under the effect of pressure oil, integrated type locating oil cylinder piston mechanism 5 can not retreat, and be blocked to during integrated type locating oil cylinder piston mechanism 5 when the main oil cylinder piston 4 of master cylinder 1 rear end retreats, master cylinder 1 to-and-fro motion under the effect of pressure oil realizes concrete conveying.
When needs move back cylinder, the oil pressure of release locating oil cylinder 6 back cavity, now integrated type locating oil cylinder piston mechanism 5 retreats, and master cylinder 1 makes main oil cylinder piston 4 drive piston rod 2 to retreat under the effect of pressure oil, thus realizes moving back cylinder function.
Claims (2)
1. a new type mining concrete wet spraying machine conveying cylinder, comprise master cylinder (1) and locating oil cylinder (6), master cylinder (1) comprises piston rod (2), master cylinder cylinder barrel (3) and main oil cylinder piston (4), and main oil cylinder piston (4) is connected with piston rod (2); Locating oil cylinder (6) comprises locating oil cylinder piston mechanism (5), locating oil cylinder cylinder barrel (8) and flange (9), it is characterized in that, described master cylinder cylinder barrel (3) is connected with locating oil cylinder cylinder barrel (8), afterbody flange (9) the Bonding pressure oil of locating oil cylinder cylinder barrel (8); Described locating oil cylinder piston mechanism (5) and piston rod (2) are without being connected.
2. new type mining concrete wet spraying machine conveying cylinder according to claim 1, it is characterized in that, described locating oil cylinder piston mechanism (5) is one-piece piston bar.
