Standby vertical upper and lower double hooks for discharge sling chain of trolley-type thermal treatment furnace charging tray

Abstract

The invention discloses standby vertical upper and lower double hooks for a discharge sling chain of a trolley-type thermal treatment furnace charging tray, which are used for automatically hanging a sling chain for a charging tray on the trolley surface of a thermal treatment furnace. The standby vertical upper and lower double hooks are characterized by comprising double hook heads, an upright post and a base plate, wherein the double hook heads are vertically connected to the upper end of the upright post; the vertical post is vertically connected with the upper surface of the base plate; the double hooks are composed of a downward outer hook and an upward inner hook; the downward outer hook is connected with the upper end of the upright post; the upward inner hook is connected with one side, towards the downward outer hook, of the upper part of the upright post; the tip of the upward inner hook is located between the inner side of the downward outer hook and the upper part of the upright post; the distances between the tip of the upward inner hook and the downward outer hook and between the tip of the upward inner hook and the upper part of the upright post are greater than the diameter of the sling chain; the tip of the upward inner hook is not lower than that of the downward outer hook; the double hook heads are orientated to the trolley and the charging tray of the to-be-hung sling chain on a sizing block; the terrain clearance of the downward hook head of the double hook heads, the distance between the standby vertical double hooks for the sling chain of the thermal treatment charging tray on the same side of the trolley, and the distance between the standby vertical double hooks for the sling chain of the thermal treatment charging tray on the same side of the trolley and the charging tray on the trolley can be determined by tests; and the base plate can be buried in the ground or can be put on the ground.

Description

technical field [0001] The invention relates to a ground auxiliary device for automatically hanging a driving chain on a material tray on the trolley surface of a heat treatment furnace. Background technique [0002] The furnace bottom structure of the existing industrial heat treatment general-purpose large-scale desktop furnace (resistance furnace or gas furnace) is usually a trolley, and several shim irons with the same width as the main body of the tray and a height of 250mm are placed horizontally on the trolley. The electric motor drives the machine to travel longitudinally on the track to enter and exit the furnace. Heat treatment workpieces are usually pre-installed on the tray with the same width as the top of the trolley, and then the tray is hoisted by the crane and placed on the trolley, and its longitudinal direction is parallel to the top of the trolley. The ears are located above the two sides of the trolley surface, and then the trolley is driven by the moto...
