Portable sand box tool overturning lifting appliance

Abstract

The invention discloses a portable sand box tool overturning lifting appliance. The portable sand box tool overturning lifting appliance is characterized in that a lifting appliance body is of a double-layer structure; gaskets (6) are arranged between a middle hanger shaft (3) and the inner layer and outer layer of the lifting appliance body; the middle of the middle hanger shaft is connected with the lower portion of a closed lifting ring in a sleeved mode, and the two ends of the middle hanger shaft penetrate through the inner layer and outer layer of the top end of the lifting appliance body separately and are fixedly connected through screw caps; the two sides of the middle hanger shaft are each provided with a fastening bolt (4) at equal intervals and are fixedly connected with the inner layer and outer layer of the lifting appliance body through screw caps (5); pulley hanger shafts II (7), hanger shafts III (10) and cross-shaped joints (8) are arranged at the two ends of the lifting appliance body; gaskets (9) are arranged between the hanger shafts II and the inner layer and outer layer of the body; the hanger shafts II penetrate through the inner layer and outer layer of the lifting appliance body and are fixedly connected through screw caps; the hanger shafts II are connected with the corresponding cross-shaped joints in a sleeved mode, and the hanger shafts III are connected with pulleys (11) in a sleeved mode; and the hanger shafts III penetrate through the two sides of the corresponding cross-shaped joints and are fixedly connected through nuts, and the pulleys are sleeved with corresponding iron chains (12).

Description

technical field [0001] The invention relates to a sling, more specifically a portable overturning sling that can be used for various sand boxes, boxed sand molds, box tooling and real objects. Background technique [0002] There are two types of "extreme" states of high and low production costs and their respective major shortcomings in the existing flipping spreaders for sand boxes and box-like tooling and objects. One is the simple (flipping) The spreader has the disadvantages of high labor intensity for the operator, low efficiency and poor work quality; the other type is the automatic or semi-automatic turning spreader with high production cost, which has the disadvantages of large equipment, high cost, low operational flexibility and safety. Low means that the operator is prone to safety accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems existing in the existing sand boxes and box-type toolin...
