Description
Technical field
The utility model relates to the capstan winch field, particularly a kind of built-in hydraulic windlass.
Background technology
Capstan winch comprises hand winch, electric capstan, hydraulic windlass and pneumatic capstan winch etc., can cooperate operations such as other instruments are removed obstacles, dilatory article, installation, is very important equipment.
Existing capstan winch, hydraulic windlass particularly, generally comprise engine installation (as HM Hydraulic Motor), transmission component, cylinder etc., engine installation and transmission component all are arranged on outside the cylinder, it is 101337644 Chinese patent as patent publication No. is 200978193 Chinese patent, patent publication No. is 201777807U Chinese patent, patent publication No., transmission component is in and exposes visible state, even is the Chinese patent medium power device of 202296948U and transmission component becomes parts separately and the cylinder branch is arranged as patent publication No..This makes the cylinder volume inside not use, and causes the overall volume of capstan winch excessive, and owing to similar reason makes the diameter of cylinder generally smaller, capstan winch is just than the difficult occasion that is used for some big loads like this.
Existing capstan winch is not provided with special brake assemblies, the stall of general dependence engine installation shuts down capstan winch, be the Chinese patent of 201842590U as patent publication No., capstan winch stall immediately in the time of so just can not need guaranteeing, and may take place when load is overweight, the phenomenon of capstan winch reversing, in order to avoid because of above-mentioned phenomenon generation safety misadventure as far as possible, this class capstan winch can only be used for the horizontal direction traction.Be provided with brake assemblies in some high-end products, it is 1241529 Chinese patent as patent publication No., in capstan winch, be provided with some friction linings, be provided with spring between the friction lining, control the cylinder of spacing to guarantee friction generation friction force to take place between friction lining when needed and be converted into the braking force brake reel of friction lining with this.The brake assemblies that this mode is set also has its defective, because friction lining is only worked when spring is in compressive state, in case outside push-tight power deficiency, friction lining just can not be worked, safety misadventure will take place and this situation occurs when needs are braked, in addition, the spring that arranges between friction lining should proof strength enough keep volume little again, has increased the productive costs of capstan winch greatly.
Summary of the invention
The purpose that the utility model will reach provides a kind of capstan winch, and transmission component and brake assemblies are not exposed to outside the cylinder.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of built-in hydraulic windlass, comprise permanent seat and engine installation, engine installation is fixed on the permanent seat, also comprise transmission component and be used for tractive, store the cylinder of hauling rope, also comprise brake assemblies, described transmission component and described brake assemblies are located in the cylinder, described engine installation is in transmission connection to drive cylinder by transmission component and described cylinder and rotates, and braking force mouth and the transmission component of brake assemblies are in transmission connection.

Further, described speed reduction gearing comprises two groups of planet circular systems, the secondary sun wheel of the primary planet carrier of one-level planet circular system and secondary planet train is in transmission connection, and the one-level satellite gear of one-level planet circular system, the secondary planet of secondary planet train wheel all mesh with internally toothed annulus; One-level sun wheel and the spline housing of one-level planet circular system is in transmission connection in the speed reduction gearing.Two groups of planet circular systems guarantee that the deceleration effect of speed reduction gearing reaches requirement, and can change two groups of parameters such as ratio of number of teeth between planet circular system according to the product of different size and demand.
Further, described brake assemblies comprises bearing, friction lining group and hydraulic control, the friction lining group comprises a slice movable friction plate and a slice static friction sheet at least at least, movable friction plate and static friction sheet are arranged in the bearing spaced reciprocally, movable friction plate is connected with described transmission component, and the static friction sheet is connected with described bearing; Spacing in the described hydraulic control control friction lining group between friction lining.This brake mode is effective, and can not cause braking force to descend because friction lining uses the back wearing and tearing for a long time.
Further, the quantity of described movable friction plate and described static friction sheet is poor≤and 1, keep movable friction plate and static friction sheet to arrange the space one by one, make the friction force maximum that produces under the identical friction lining quantity.
Further, the friction lining of described friction lining group is circular, described movable friction plate is connected with the spline housing spline, movable friction plate and the coaxial synchronous rotation of spline housing, the friction lining friction face that ring-type arranges is big, stressed evenly, and be the spline housing braking from the power intake of transmission component directly, braking effect is better, also can reduce the wearing and tearing of other parts of transmission component simultaneously.
Further, described hydraulic control comprises hydraulic efficiency gear and piston, along being parallel to the axial direction activity of described friction lining, the state of piston when the stroke two ends is respectively and leaves the friction lining group, pushes the friction lining of friction lining group to make the spacing of adjacent friction lining in the friction lining group be zero along being parallel to the axial direction of described friction lining hydraulic efficiency gear by the fluid control piston.Hydraulic efficiency gear comprises HM Hydraulic Motor, control cock piece, y-shaped ring etc., provides the hydraulic oil of hydraulic pressure to flow out from the control cock piece, and the fluid control piston holds out against or disengaging friction sheet group, has enough friction force when guaranteeing the work of friction lining group.
Further, form hydraulic cavities between a side of the close described friction lining group of described piston and the described bearing, be provided with path in the described bearing, path is communicated with hydraulic cavities and described hydraulic efficiency gear.Under this structure design, be full of hydraulic oil in the hydraulic efficiency gear input end path, when increasing oil pressure, push piston and leave the friction lining group, the friction lining group seldom or not produces friction force, after hydraulic efficiency gear reduces the oil pressure of hydraulic oil, make piston make the friction lining group produce enough braking forces to spline housing along being parallel to the axial direction of friction lining near the friction lining group and finally holding out against the friction lining group.
Further, be provided with seal ring in the described bearing, seal ring seals described hydraulic cavities.Except preventing fluid seepage other positions in the capstan winch, also make the better effects if of hydraulic control.
Further, be provided with spring between described piston and described bearing, action of the spring produces in piston and makes the piston top to the trend of friction lining group, auxiliary hydraulic set work, thereby brake assemblies can not take place to make piston can't hold out against the friction lining group and then cause the accident that can't brake because of the hydraulic efficiency gear fault when needs are braked.
After adopting technique scheme, the utlity model has following advantage:
Transmission component and brake assemblies are located in the cylinder, take full advantage of the space in the cylinder, make the Winching device overall volume less, can increase the diameter of cylinder simultaneously, make capstan winch applicable to the occasion of bigger load.
