Description

Push-pull disc trolley

Technical Field

The utility model relates to a push-pull tray trolley for pushing and pulling a tray into and out of a heat treatment furnace.

Background

In order to feed or withdraw a tray loaded with material into or from a heat treatment furnace, a push-pull tray trolley with a hook member is generally used, and a driving mechanism on the push-pull tray trolley drives the hook member to swing relative to a frame so as to realize connection or disconnection with the tray.

The driving mechanism often adopts a hydraulic mechanism, but because the push-pull disc trolley needs to reciprocate, a hydraulic station arranged on the ground and used for providing hydraulic oil for the hydraulic mechanism needs to be connected with the hydraulic mechanism through a complex pipeline, the pipeline needs to be repeatedly pulled, leakage is easy, and the maintenance cost is high. Some driving mechanisms adopt electric push rods, and because the telescopic rods of the electric push rods are longer, the space required by swinging is larger, and the manufacturing cost and the installation requirements are higher, so that the electric push rods are not suitable for popularization and use.

Disclosure of Invention

The utility model provides a push-pull tray trolley which is simple in structure, convenient to operate, low in cost and suitable for popularization, and is used for realizing feeding and discharging of a material tray of a heat treatment furnace.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

a push-pull disc trolley comprises a frame with rollers at the bottom, a hook component rotatably arranged at least one end part of the frame, a driving mechanism for driving the hook component to swing relative to the frame,

the hook component comprises a swing rod and a hook, one end of the swing rod is fixed on a pivot rotatably arranged on the frame, and the other end of the swing rod is fixed with the hook; the driving mechanism comprises a driving motor arranged on the frame, and the driving motor is connected with the pivot through a gear transmission mechanism or a chain transmission mechanism to drive the pivot to rotate.

The push-pull disc trolley comprises a driving sprocket arranged on an output shaft of a driving motor, a driven sprocket arranged on a pivot, and a chain encircling the driving sprocket and the driven sprocket.

The push-pull disc trolley comprises a gear transmission mechanism, wherein the gear transmission mechanism comprises a driving gear arranged on an output shaft of a driving motor and a driven gear arranged on a pivot, and the driving gear is meshed with the driven gear.

In the push-pull disc trolley, the left side and the right side of one end of the frame are respectively provided with one hook component, and each hook component is connected with one driving mechanism.

In the push-pull disc trolley, the front end and the rear end of the frame are provided with the hook members; each hook member is coupled to a drive mechanism.

In the push-pull disc trolley, the left side and the right side of each end of the frame are respectively provided with one hook component.

In the push-pull disc trolley, the front end and the rear end of the frame are provided with the hook members; the pivot chain wheels are arranged on two pivots of the front hook component and the rear hook component, and the pivot chain surrounds the two pivot chain wheels; a drive sprocket is arranged on one pivot, a drive sprocket is arranged on the output shaft of the drive motor, and a drive chain surrounds the drive sprocket and the drive sprocket; the driving motor rotates, and drives the two pivots to synchronously rotate through the driving sprocket, the transmission chain, the transmission sprocket, the pivot sprocket and the pivot chain; one of the two hook members is in a horizontal state and the other hook member is in a vertical state. For example, pivot sprockets are provided on the pivot shaft in the hanger member at the front end of the frame and on the pivot shaft in the hanger member at the rear end of the frame, the pivot chain encircling both pivot sprockets; a drive sprocket is arranged on a pivot in a hook component at the front end of the frame or a pivot in a hook component at the rear end of the frame, a drive sprocket is arranged on an output shaft of the drive motor, and a drive chain surrounds the drive sprocket and the drive sprocket; the driving motor rotates, and the driving chain wheel, the transmission chain wheel, the pivot chain wheel and the pivot chain drive the pivots in the hook parts at the front end and the rear end to synchronously rotate; the hooks of the hook members at the front and rear ends are in a horizontal state and the other hooks are in a vertical state. Because the front and rear hooks cannot be simultaneously in the working horizontal state, only one hook can work (in the horizontal state) and the other hook can not work (in the vertical state). Therefore, the utility model uses the characteristic that the front and rear hook parts are driven by a set of driving mechanism, thereby saving the cost, and reducing the output power of the driving motor (because the vertical hook and the horizontal hook are linked, when the vertical hook is turned to the horizontal state, the horizontal hook is driven to be turned to the vertical state, and the boosting effect is achieved).

The push-pull disc trolley is characterized in that a hook component is arranged on the left side and the right side of each end of the frame; two swing rods in the left and right hook parts at the same end of the frame are fixed on the same pivot.

In the push-pull disc trolley, the connecting part is arranged at the bottom of the frame and is used for being connected with the trolley driving device for driving the frame to move.

The beneficial effects of the utility model are as follows:

the utility model adopts a common driving motor, a gear transmission mechanism or a chain transmission mechanism and the like to drive the pivot to rotate, has simple structure, only swings the swing rod and the hook, has small stroke of the whole moving part, is quick to install, is convenient to use and has lower cost. And the chain transmission mechanism is preferentially adopted, so that the precision requirements of manufacturing the chain transmission mechanism and the like are lower, the installation is more convenient, and the cost is further reduced. Each hook member is connected to a drive mechanism, one of which drives one hook member, which is convenient to control. Moreover, if the tray (and the material loaded thereon) is light, etc., only one hook member at one end is required to be attached to the tray.
