Abstract
The utility model discloses a stirring shaft for a wet type concrete sprayer. The stirring shaft comprises a stirring shaft body (1), a left stirring screw (2) and a right stirring screw (3), wherein the left stirring screw (2) and the right stirring screw (3) are arranged at the two ends of the stirring shaft body (1) respectively; one end of the stirring shaft body (1) is connected with a motor connecting shaft (4), and the other end of the stirring shaft body (1) is connected with a supporting shaft (5); an inner ring of a flange (1a) is connected with the stirring shaft body (1) through a key; and a joint surface between a motor connecting disk (4a) and the flange (1a) has a radial limiting structure. The stirring shaft has a simple structure and skillful concept; and by designing the stirring shaft in a three-section connection mode, the aim of conveniently disassembling the stirring shaft is fulfilled, and the damage of related components such as a seal ring, a bearing and the like during disassembly can be effectively prevented.
Description
Technical field
The utility model belongs to the bridge technology field, relates to a kind of shaft that is used for wet concrete sprayer concretely.
Background technology
Wet type concrete plunger spraying machine (wet shot machine) is widely used a kind of construction equipment in the fields such as railway tunnel, highway tunnel, water power tunnel, underground power house, subway engineering, geotechnics, military underground construction.Wet type concrete plunger spraying machine (wet shot machine) adopts the plunger spray regime, the concrete emitted dose, and the expulsion pressure height, hopper capacity is big, the productivity ratio height.The hopper mixing plant is a monolithic in the existing spraying machine, as shown in Figure 2: mainly comprise, bearing support 7, hopper 9, shaft 10, S valve 11, shaft 10 is that integral shaft one end connects rotation motor in this structure, one end is installed on the bearing support 12, good multi-part is consumable accessory in mixing plant needs often to change, for example the S valve 11, must dismantle shaft 10 and associated components when changing consumable accessory, easily cause the damage of the sealing ring at shaft two ends and bearing etc. and lose time, reduce production efficiency, concrete easy to leak.
The utility model content
The purpose of this utility model has provided a kind of convenient disassembly of simple in structure, shaft, has effectively reached the shaft that is used for wet concrete sprayer that prevents that sealed at both ends circle of shaft and bearing are damaged.
The technical solution of the utility model is as follows:
A kind of shaft that is used for wet concrete sprayer, comprise the shaft body, left side agitating auger and right agitating auger, described left agitating auger and right agitating auger are installed in the two ends of described shaft body respectively, one end of described shaft body connects the motor connecting axle, the other end connects bolster, wherein said motor connecting axle is connected with the flange of described shaft body end suit by end fixed motor terminal pad, this flange inner ring is connected by key with described shaft body, and the bonding surface between described motor terminal pad and the flange forms radially position limiting structure.
Adopt the said structure key to be original monolithic shaft has been adopted the syllogic design promptly: the motor connecting axle, shaft body and bolster, and being connected by motor terminal pad between motor connecting axle and the shaft body and flange, flange is contained on the shaft body by the key adapter sleeve, realized the transmission of power when working like this, radially position limiting structure can prevent that diaxon is in radially dislocation, when needs dismountings shaft body, unclamp being connected of motor terminal pad and flange, break away from the inside slippage of flange radially spacing, unclamp being connected between shaft body and the bolster simultaneously, so just can take off the shaft body, make things convenient for the replacing of other consumable accessory, sealing ring in this structure, associated components such as bearing are arranged on the motor connecting axle, on the bolster, do not need dynamic seal ring in the dismounting shaft body process, associated components such as bearing just can reach like this shaft body pulled down to changing consumable accessory provides the space while effectively to prevent sealing ring, the damage of associated components such as bearing in unloading process.
By on described motor terminal pad and flange, boss being set respectively and groove forms the concavo-convex radially position limiting structure that matches.
Be connected with the bolster terminal pad by the shaft terminal pad between described shaft body and the bolster.
Shaft terminal pad and bolster terminal pad are fixedly connected on respectively on shaft body and the bolster, can realize dismounting by the bolt connection between two terminal pads.
Described motor connecting axle is provided with spline coupling, clutch shaft bearing lid and second bearing cover, is set with clutch shaft bearing between the described clutch shaft bearing lid and second bearing cover.
Described bolster is provided with the 3rd bearing cover, second bearing, and described second bearing is positioned at the outer end of described the 3rd bearing cover.
Beneficial effect: the utility model is simple in structure, be skillfully constructed, by shaft being designed to the damages of associated components in disassembly process such as three sections connected modes, the energy-conservation purpose that reaches the easy disassembly shaft, effective means sealing ring again, bearing.
