Abstract

Provided is a track rotation docking device. A section of light rail track is cut to be used as a rotation track, a stepped shaft is welded at the center of the bottom of the light rail track, and a shaft shoulder of the stepped shaft is supported on a single direction thrust ball bearing. A deep groove ball bearing is further mounted on the small shaft diameter portion of the stepped shaft. The stepped shaft is fixedly connected to a bearing pedestal through the single direction thrust ball bearing and the deep groove ball bearing, the bearing pedestal is fixedly welded to a steel plate, and the steel plate is further fixedly welded to the end portion of a fixing support. Lug plates are welded on the side face of the section of light rail track, and an oil cylinder is connected with the lug plates and drives the rotation track. The track rotation docking device is simple in structure, reliable in movement, flexible in automatic control, good in docking effect, and capable of completely meeting the spacing docking transition demand between two sections of tracks so that a distributing bucket can pass by smoothly on the device.

Description

A kind of track rotation docking facilities

Technical field

The utility model relates to constructional engineering machinery technical field, is specifically related to a kind of track rotation docking facilities.

Background technology

In the suitability for industrialized production of prefabricated building, wallboard for build-up type integrated building is manufactured, there is a kind of formwork erection cast concrete mode at present, thereby need to develop formwork erection cast material distributing machine.In formwork erection cast material distributing machine, there is cloth bracket and a fixed fixed mount of a walking, light rail track is all installed on it.Because the walking of cloth bracket is that the walking on the light rail track of ground realizes by the road wheel on its walking beam, for guaranteeing road wheel, on light rail track, can normally walk, between road wheel and light rail track, leave certain gap, cloth bracket just has deflection in position in the process of walking like this.When cloth bracket runs to while aliging with fixed mount, for guaranteeing that it does not have interference each other, just need leave enough spacing.And this track space is if do not docked compensation, the walking beam of cloth bucket can not be walked over.For guaranteeing that cloth bucket can run to fixed mount from cloth bracket smoothly, the spacing between both tracks just need have the transition apparatus of an orbital docking compensation.

Summary of the invention

Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and a kind of track rotation docking facilities is provided, simple in structure, reliable in action, controls flexibly automatically, docks effectively, can realize the smooth transition between track space.

The technical solution adopted in the utility model is:

A kind of track rotation docking facilities, cut one section of light rail track as swing-around trajectory, a stepped shaft of bottom centre's welding at this section of swing-around trajectory, the shaft shoulder of stepped shaft is supported on single direction thrust ball bearing, the small axle diameter position of stepped shaft is also provided with a deep groove ball bearing, stepped shaft is fastened on bearing seat by single direction thrust ball bearing and deep groove ball bearing, bearing seat is weldingly fixed on steel plate, steel plate is welded and fixed with the end of fixed mount again, at the side of described one section of swing-around trajectory welding otic placode, oil cylinder connects otic placode and drives swing-around trajectory.

In technique scheme, one section of described its two ends of swing-around trajectory are cut into and are take the concentric circular arc that length center-point is the center of circle, in contrast should, light rail track termination on cloth bracket and fixed mount, circular-arc with swing-around trajectory concentric also will be cut in the position of docking with described one section of swing-around trajectory.

In technique scheme, one section of described swing-around trajectory vertically exceeding 0.2-0.3mm on height, keeps the gap of 3-4 mm than the light rail track on fixed mount and on cloth bracket in horizontal length direction.

Principle of work:

When cloth bracket runs to fixed mount, align, cloth bucket need be when cloth bracket runs to fixed mount, oil cylinder stretch out promote swing-around trajectory rotation to cloth bracket, the fixed mount aligned position that gets on the right track, cloth bucket is passed through smoothly from it; When cloth bucket has connect material and has been back on cloth bracket by fixed mount from mixing plant after, cloth bracket need be walked while leaving fixed mount, oil cylinder bounces back and pulls swing-around trajectory rotation 90o, the position that cycle is got on the right track and is vertical with fixed mount, unlikely and swing-around trajectory interference when cloth bracket walking is left.Perseveration like this.

Advantageous effect:

Simple in structure, reliable in action, automatically controls flexibly, docks effectively, can meet the demand that spacing between two sections of tracks is docked transition completely.Cloth bucket can be passed through from it smoothly.

The specific embodiment

Referring to Fig. 1-Fig. 5, track of the present utility model rotation docking facilities, its structure is: cut one section of light rail track of certain length, take this length center-point is the center of circle, this section of track two ends is cut into the circular arc of concentric.Bottom centre at this section of track is a stepped shaft of home position welding, and the shaft shoulder position of axle is supported on single direction thrust ball bearing, and to bear pressure total weight in orbit, a deep groove ball bearing is also equipped with at the small axle diameter position of axle.By single direction thrust ball bearing, deep groove ball bearing, axle is fixed on bearing seat, the tip of the axis also pins with circular nut.Bearing seat and a block plate are weldingly connected, this steel plate is weldingly connected with the end of fixed mount again, and make track on this section of swing-around trajectory and fixed mount and on cloth bracket vertically in short transverse, exceed 0.2 ~ 0.3mm, the gap of the 3 ~ 4mm that keeps having an appointment in horizontal length direction.Certainly, the track on cloth bracket and fixed mount also will be cut into the circular shape with the circular arc concentric of swing-around trajectory in the position of section swing-around trajectory docking therewith.Side welding upper ear plate at this section of swing-around trajectory is connected with oil cylinder again, and that utilizes oil cylinder flexiblely promotes this section of swing-around trajectory and rotate.This section of swing-around trajectory can, by axle around its central rotation, can bear from the total weight on track again like this.When cloth bucket need to be from it by time, swing-around trajectory rotation to cloth bracket and fixed mount on track aligned position; After cloth bucket goes mixing plant to connect material to be back on cloth bracket, cloth bracket need be walked while leaving fixed mount, and swing-around trajectory again contrarotation 90o rotates the position of getting on the right track and being vertical with fixed mount, cloth bracket is unlikely with swing-around trajectory and interferes.Perseveration like this.
