Compared with the prior art, the utility model has substantial characteristics and progress, and in particular has the following advantages:

1. the weight of the cement filler is adopted to replace cast iron weight, replacement of counterweight materials is achieved, cost is saved, the built-in reinforcing bars strengthen the structural strength of the cement filler, the outer layer is provided with a plastic shell for packaging, a filling port is reserved at one end only, a full-package structure is formed, packaging is advanced, sealing inaccuracy caused by post packaging is avoided after packaging is achieved, and further structural stability of the counterweight is improved.

2. The anti-corrosion paint coating made of asphalt paint is sprayed outside the plastic shell, so that the corrosion resistance can be improved, the asphalt paint has stronger toughness and corrosion resistance, and the surface flatness is easy to control, so that the stacking of the weight blocks is smoother.

3. In structural design, the two ends are provided with rounded convex-shaped ends for being clamped into the counterweight frame, so that the rounded structure is not easy to be clamped; semicircular openings on the front side and the rear side of the bottom end are convenient for manual carrying.

Detailed Description

The technical scheme of the utility model is further described in detail through the following specific embodiments.

As shown in fig. 1-4, an elevator counterweight block comprises a plastic shell 1, a cement filler 2 and reinforcing bars 3, wherein the plastic shell 1 is integrally in a strip shape, two transverse ends of the plastic shell 1 are provided with convex-shaped ends 4, corners of the convex-shaped ends 4 are in rounded transition, the convex-shaped ends 4 at the two ends are used for being clamped into a counterweight frame, and a rounded structure can be prevented from being clamped, and access and adjustment are not easy to influence.

The bottom of both sides all is provided with two semicircular openings 5 that are used for transporting around the plastic housing 1, and the position of two semicircular openings 5 of same side is along central line symmetry for as force application point and setpoint in the in-process of transport, prevent that the elevator from sliding the pouring weight in the handling.

In other embodiments, semi-circular cutouts at the same end on different sides are provided through for penetration and handling by a forklift.
