Hydraulic lift mechanism for prestressed concrete slab forming machine

Abstract

The invention discloses a hydraulic lift mechanism for a prestressed concrete slab forming machine. The hydraulic lift mechanism comprises a rack and a vertical hydraulic lifting device which is arranged at the front end of the rack. The front end of the rack is fixedly connected with a support frame, the lower portion of the support frame is fixedly connected with a fixing sleeve, a lift rotating shaft passes through the fixing sleeve and can rotate in the fixing sleeve, and both ends of the lift rotating shaft are fixed connected to a rotating arm. The outside surface of the tail end of the rack is correspondingly fixedly connected with two crank shafts which are rotationally connected with a crank arm; and the lower end of the crank arm is fixedly connected with a lifting axle which is drivingly connected with a lifting wheel. The upper end of the crank shaft is hinged to a lever; and the other end of the lever is hinged to the upper end of the rotating arm. The hydraulic lift mechanism is directly connected to the rack, the trouble of frequent loading and unloading is eliminated. By means of hydraulic lift, the lifting is smooth and steady, the turning radius is small, the operation is effortless and the safety is reliable.

Description

Technical field [0001] The invention relates to a lifting mechanism of building material forming equipment, in particular to a hydraulic lifting mechanism of a prestressed concrete slab forming machine. Background technique [0002] At present, among building material forming equipment, the widely used and relatively mature prestressed concrete hollow floor extrusion molding machine or push molding machine, prestressed concrete hollow stair stepping extrusion molding machine or push molding machine, prestressed concrete hollow Pre-stressed concrete slab forming machine such as lintel extrusion molding machine or push forming machine. The pre-stressed concrete slab forming machine extrudes the raw materials during production. At the same time, the frictional resistance between the pre-stressed concrete slab belt and the ground reacts with the spiral Reamers or sliders make the whole machine move forward. Such equipment is limited by the length of the production line during use. Af...
