A concrete pipe pile mold spreader

Abstract

The invention discloses a concrete tubular pile die lifting appliance which comprises a cross beam, cover die grapnels and bottom die grapnels, more than one group of cover die grapnels and more than one group of bottom die grapnels are available; the cover die grapnels are fixedly connected to the cross beam; and the bottom die grapnels are rotatably connected to the cross beam. The concrete tubular pile die lifting appliance provided by the invention is simple in structure and good in reliability, can lift and transport cover dies and bottom dies simultaneously, can be unifiedly used among all the working procedures of the tubular pile, and can reduce labor employment, improve the working efficiency, and eliminate the potential safety hazards.

Description

technical field [0001] The invention relates to a concrete pipe pile mold spreader, in particular to an automatic clamping device for simultaneously hoisting a concrete pipe pile mold cover mold and a bottom mold. Background technique [0002] In the production process of concrete pipe piles, the molds used to produce concrete pipe piles (hereinafter referred to as pipe molds) need to be hoisted and circulated in various processes. In the process of pipe mold circulation in each process, the traditional method is the hanging chain hook method. The method is that one end of the hanging chain is hung on the big hook of the driving, and the other end is connected to the small hook. The small hook is hung on the pre-set pipe mold. On the ear, the disadvantage is that the pipe mold needs to be hooked and unhooked manually every time it is transferred between various processes, which poses a great safety hazard and wastes manpower. In recent years, two kinds of pipe mold automati...

Problems solved by technology

The disadvantage of this mechanism is that it can only grab the cover mold, and the four-bar linkage mechanism adopts too many hinge points, the mechanism is cumbersome, it is inconvenient to maintain, and the maintenance cost is high

[0004] 2. Grasp the cover mold and bottom mold spreader at the same time, if attached figure 2 As shown, the working points of the grapple of the cover mold and the grapple of the bottom mold of this kind of sling are distributed at different heights. The disadvantage of this sling is that the grapple of the cover mold is similar to the first point above, and the grapple of the bottom mold Generally, there are fixed type and rotary type. The disadvantage of the fixed type is that the hook of the bottom mold is fully opened when the cover mold is grasped, the overall working width of the spreader is large, and the work is inconvenient. The disadvantage of the rotary type is that the mechanism is complicated and the reliability is poor
