Abstract
The utility model belongs to a special spanner for repairing continuous casting crystallizers in iron and steel plants, and particularly relates to a spanner for continuous casting crystallizers. The head of a thrust rod is fixedly connected with a sleeve with an inner hexagonal hole, symmetrical steel tube cross arms are fixedly connected to the tail of the thrust rod, and axes of the steel tube cross arms are perpendicular to the axis of the thrust rod. The spanner is simple and reasonable in structure and convenient in operation of crystallizer maintenance and replacement, is safe and reliable, saves time and labor, and is high in work efficiency.
Description
Technical field
The utility model belongs to the special spanner, particularly continuous cast mold spanner of steel plant's maintenance continuous cast mold.
Background technology
Iron and steel enterprise's cast steel continuous cast mold is the heart of continuous casting, and the once cooling of molten steel just relies on crystallizer to realize, but crystallizer in use for some time, owing to situations such as copper pipe wear and tear, the crystallizer flange seal is not tight, needs to change crystallizer and be convenient to maintenance.
Used tool was common general utility wrench when crystallizer was changed.During actual the use, because the working environment high temperature humidity of nut, nut and screw rod easily rust are lived, and need to block the crystallizer hold-doun nut with spanner, and weight beats the spanner afterbody, and nut is unclamped, and crystallizer could be changed.In beaing the nut process, firmly light, bolt is difficult for dismantling; Firmly big, then easily slippage, weight may beat hand or shank.
Because space, crystallizer set bolt position is comparatively narrow and small, in loose nut process, middle job contract needs to squat in the other operation of crystallizer.Can't change fast, operating efficiency is relatively low.
The utility model content
The purpose of this utility model is to provide a kind of continuous cast mold spanner, and it is simple and reasonable for structure, and the maintain and replace crystallizer operation is convenient, and is safe and reliable, time saving and energy saving, high efficiency.
The purpose of this utility model is achieved in that a kind of continuous cast mold spanner, the head of boosting-rod affixed have in the sleeve in hexagon hole, the afterbody of boosting-rod affixed steel pipe transverse arm, the axis of steel pipe transverse arm and the boosting-rod axis normal of symmetry.
Because the boosting-rod of the utility model setting has increased the arm of force length of spanner, when changing crystallizer, match with the hold-doun nut of crystallizer by the sleeve of boosting-rod head, in the aft mounted steel pipe transverse arm of boosting-rod, insert the crow bar rotation and get final product.Owing to effectively increased the arm of force, when changing crystallizer, need not to beat the spanner afterbody with weight, just can easily the hold-doun nut of crystallizer be unloaded down.Simultaneously, security incidents such as hand, leg have been avoided hindering.Owing to be provided with boosting-rod, improved operating personnel's operation height, the operative employee need not to squat and works between crystallizer.Prove that through practical application originally by the normal the fastest needs of crystallizer 10 minutes of changing, use the spanner after improving, the time of changing crystallizer can be controlled in 5 minutes.The utility model is simple and reasonable for structure, and the maintain and replace crystallizer operation is convenient, and is safe and reliable, time saving and energy saving, high efficiency.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing,
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is A～A sectional structure schematic diagram of Fig. 1.
The specific embodiment
A kind of continuous cast mold spanner, as shown in Figure 1 and Figure 2, the head of boosting-rod 2 affixed have in the sleeve 1 in hexagon hole, the afterbody of boosting-rod 2 affixed the symmetry steel pipe transverse arm 3, the axis normal of the axis of steel pipe transverse arm 3 and boosting-rod 2, steel pipe transverse arm 3 is the both sides that the center is symmetrically distributed in boosting-rod 2 with the axis of boosting-rod 2.Match with the hold-doun nut of continuous cast mold in the interior hexagon hole of sleeve 1.The length of boosting-rod 2 is 600-650mm.Determine the length of boosting-rod 2 according to crystallizer bearing to the height of upper flange, make operating personnel need not to squat and between crystallizer, work.
