Abstract
The utility model discloses a shaft pulling device used for a backseat of an excavator. The shaft pulling device comprises three screws, a front support, three driven gears, a driving shaft, a rear support, a handle, a rocker, four front support bearings, four rear support bearings and a driving gear, wherein the three driven gears are arranged in the front support, the four front support bearings are arranged on the front support, the four rear support bearings are arranged on the rear support, one end of each screw penetrates through the corresponding front support bearing and is fixedly connected with the corresponding driven gear, the driving gear is fixedly connected with the driving shaft and meshed with the three driven gears at the same time, the rear support is fixedly connected with the front support, the four rear support bearings are matched with end portions of the three screws and the driving shaft respectively, the rocker is arranged outside the rear support, one end of the rocker is connected with the driving shaft, and the handle is arranged at the other end of the rocker. The three screws simultaneously work so that it can be ensured that force is evenly exerted on a shaft baffle and the shaft baffle is pulled out, a shaft which can be easily damaged and parts matched with the shaft can be protected, and meanwhile potential safety hazards can be reduced.
Description
Technical field
The utility model relates to a kind of shaft device that pulls out for excavator back seat, belongs to excavator technical field.
Background technology
Excavator back seat is connected by axle with turntable, the tradition detachment mode way that conventionally adopts "painted-face" character in opera to knock, except existing potential safety hazard, on coordinating also between axle and swing arm back seat and turntable producing certain impact, due to limited space, the tool box of dismantling of sometimes having to.This method operating time is long, and efficiency is low, and the swing arm back seat and the turntable aperture that easily axle are coordinated affect, in the situation that being subject to rainwater corrosion serious, "painted-face" character in opera knock the damage that more easily causes axle and matching part.
Summary of the invention
The problem existing for above-mentioned prior art; the utility model provides a kind of shaft device that pulls out for excavator back seat, adopts three screw rods guarantee of work simultaneously axle bumper plate uniform stressed to extract, time saving and energy saving; the parts that protection is held flimsy axle and coordinated with it reduce potential safety hazard simultaneously.
To achieve these goals, the technical solution adopted in the utility model is: a kind of shaft device that pulls out for excavator back seat, comprise three screw rods, front bearing, three driven gears, driving shaft, rear support, handle, rocking bar, four front supporting bearings, four rear support bearings and driven wheel, three driven gears are placed in front bearing, four front supporting bearings are contained on front bearing, and four rear support bearings are contained on rear support; One end of three screw rods is fixedly connected with three driven gears respectively through front supporting bearing, and driven wheel is fixedly connected with driving shaft simultaneously and meshes with three driven gears; Rear support is fixedly connected with front bearing, and four rear support bearings coordinate with end and the driving shaft of three screw rods respectively; Rocking bar is arranged on the outside of rear support, and one end of rocking bar is connected with driving shaft, and handle is contained on the other end of rocking bar.
Further, between front bearing and rear support, be bolted.
The beneficial effects of the utility model are: simple to operate; easy to use; only need rotary handle can realize the dismounting of back seat rotating shaft; adopt three screw rods guarantee of work simultaneously axle bumper plate uniform stressed to extract; time saving and energy saving; protect the parts that hold flimsy axle and coordinate with it, reduced potential safety hazard simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Schematic diagram when Fig. 2 is the utility model work.
In figure: 1, screw rod, 2, front bearing, 3, driven gear, 4, driving shaft, 5, rear support, 6, handle, 7, rocking bar, 8, bolt, 9, rear support bearing, 10, driven wheel, 11, back seat turntable, 12, axle bumper plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model comprises three screw rods 1, front bearing 2, three driven gears 3, driving shaft 4, rear support 5, handle 6, rocking bar 7, four front supporting bearings, four rear support bearings 9 and driven wheel 10, three driven gears 3 are placed in front bearing 2, four front supporting bearings are contained on front bearing 2, and four rear support bearings 9 are contained on rear support 5; One end of three screw rods 1 is fixedly connected with three driven gears 3 respectively through front supporting bearing, and driven wheel 10 is fixedly connected with driving shaft 4 simultaneously and meshes with three driven gears 10; Rear support 5 is fixedly connected with front bearing 2, and four rear support bearings 9 coordinate with end and the driving shaft 4 of three screw rods 1 respectively; Rocking bar 7 is arranged on the outside of rear support 5, and one end of rocking bar 7 is connected with driving shaft 4, and handle 6 is contained on the other end of rocking bar 7.
As a kind of improvement of the present utility model, between front bearing 2 and rear support 5, by bolt 8, be connected; With bolts, when internal gear damages, can easily open front bearing 2 and rear support 5 and keep in repair.
During use, first on the axle bumper plate 12 of back seat axle, offer three with three screwed holes that screw rod 1 matches of the present utility model, by three screwed holes on three screw rods, 1 aiming axis baffle plate 12 of the present utility model, then rotary handle 6 makes three synchronized in the same way rotations of screw rod 1 by the power transmission of driven wheel 10 and three driven gears 3; When the top of screw rod 1 rotating contact is during to back seat turntable 11, screw rod 1 cannot move on, and now continues rotary handle 6, and screw rod 1 can be to the outside power of axle bumper plate 12, and then axle bumper plate 12 and connected back seat rotating shaft are moved axially along screw rod 1, back seat rotating shaft is extracted the most at last.
