Push-pull hook structure for multi-purpose chamber furnace push-pull vehicle

Abstract

The invention discloses a push-pull hook structure for a multi-purpose chamber furnace push-pull vehicle, which comprises a pushing part and a pull hook part and is characterized in that the pushing part comprises a pushing block and a frame; the frame is formed by connecting a push plate, lateral plates on both sides and a fixing plate end to end; the lateral plates on both the sides are symmetrically provided with two sliding holes respectively; the end of the frame, which is close to the push plate, is provided with a limiting pin penetrating inwards; a sliding pin is arranged in the sliding holes; the pull hook part comprises a connecting part and a clamping hook part connected with the connecting part; the connecting part is in pin connection with the lateral plates on both the sides by the sliding pin and has freedom degree of center rotation; the upper surface of the connecting part is provided with a connecting hole; the pushing block passes through the connecting hole; the top of the pushing block is provided with a shaft hole; a pin passes through the shaft hole; the clamping hook part is arranged above the push plate; the front end of the clamping hook part extends outwards and is bent downwards to form an inverted hook; the joint of the bottom surface of the clamping hook part and the connecting part is an inclined plane; and the inclined plane is abutted against the limiting pin. Through the adoption of the structure, production efficiency is improved and production cost is reduced.

Description

Technical field [0001] The invention relates to a box-type multi-purpose furnace accessory, in particular to a push-pull hook structure for a box-type multi-purpose furnace push-pull car. Background technique [0002] Sealed box-type multi-purpose furnaces have been widely used in the heat treatment industry in my country. Push-pull hooks are required to perform the operation of workpieces in and out of the furnace on the push-pull cart of the box-type multi-purpose furnace. [0003] In the prior art, the push-pull hook has only two working modes: push and pull. When the two working modes of push and pull need to be converted mutually, the push-pull hook needs to be moved to the initial position, and then a special turning hook mechanism is used to complete the turning hook. To realize the conversion from push-to-pull or pull-to-push, this kind of push-pull hook needs to be equipped with a special hook turning mechanism, and a corresponding electrical control system can be automate...

AI Technical Summary

Problems solved by technology

[0005] 1. The traditional push-pull hook only has two working modes: push and pull, and when the two working modes need to be converted to each other, a set of special hook turning mechanism and an electrical control system used in conjunction with the turning hook mechanism are required, which is inefficient. high cost;

[0006] 2. When performing the slow cooling process, it is necessary to install a cylinder on the top of the furnace to make the push-pull hook separate from the material frame. The efficiency is relatively low, the cost is relatively high, and the furnace space of the multi-purpose furnace is occupied.
