Mold stripping and lifting tool device for drum

Abstract

The invention discloses a mold stripping and lifting tool device for a drum. The mold stripping and lifting tool device for the drum comprises a lifting arm, lock tongue fixing devices and a main body structure, wherein the lifting arm is a portal frame lifting arm; a lifting ring is arranged in the center of the upper part of the lifting arm; the lock tongue fixing devices are leftwards and rightwards symmetrically connected to the lower ends of two sides of the hoisting arm respectively; the lock tongue fixing device comprises a pedestal, a lock tongue, a restoring spring and a handle; the lower end of the lock tongue is rotatably connected to the pedestal; one end of the handle is fixedly connected with the lock tongue; the restoring spring is arranged between the sidewall of the lock tongue in the pedestal and the inner wall of the pedestal; the lock tongue is obliquely arranged under the effect of the restoring spring; a clamping port is formed at the upper end part of the lock tongue; the main body structure is annular; and the lock tongue fixing device is leftwards and rightwards symmetrically fixed and arranged at the circumference of the main body structure. By adopting the mold stripping and lifting tool device for the drum, the producing cost can be reduced, and the maximum usable space can be ensured as well; and the mold stripping and lifting tool device for the drum has the advantages of being simple and convenient to operate, and convenient to use.

Description

technical field [0001] The invention relates to a mold ejecting sling device, which is a mold ejecting sling used for a concrete mixing and transporting machine, in particular to a mixing drum ejecting sling device. Background technique [0002] Most of the mixing drums used in concrete mixer trucks are olive-shaped, generally divided into three sections: front cone, middle cylinder, and rear cone. The shape and size of the mixing drum are guaranteed by the front, middle, and rear three-section tooling respectively. For the convenience of assembling and demoulding, in terms of process arrangement, the mixing cylinder is made vertically, and the tailor welding procedure is: first hoist the front cone into the tooling of the front cone, then hoist into the head, and press it in place; then assemble Helical blade; secondly, stack the cylinder together with the tooling on the front cone tooling, butt joint and tailor-weld the blades; finally stack the completed rear cone togethe...

AI Technical Summary

Problems solved by technology

The disadvantage is that the loss of the wire rope is serious

With the continuous increase of the volume of the mixing drum, the length of the mixing drum is also increasing. Due to the influence of the space of the site, this lifting method is becoming less and less suitable for new production needs.
