Large-scale building material lifting and conveying device

Abstract

The invention discloses a large-scale building material lifting and conveying device. The device comprises a top plate, a wind-up roll, a steel strand, a vertical plate, a lifting sliding rail, a lifting frame, a pressing plate, two clamping arms; a clamping sliding rail and a base, wherein the top plate is fixed at the top end of the vertical plate; the bottom end of the vertical plate is fixed on the base; a counterweight is mounted in the base; the lifting sliding rail is mounted on the front side surface of the vertical plate; and the lifting frame is glidingly mounted on the lifting sliding rail. Through positive and negative rotation of the wind-up motor, the steel strand is driven to be wound on the wind-up roll or unfolded from the wind-up roll, so that the lifting frame is drivento move up or down along the lifting sliding rail, so as to lift large-scale building materials placed on the bottom plate and clamped by the clamping arms, or the lifting frame is driven to fall offso as to lift the large-scale building materials again, therefore, the operation is convenient and rapid and the stability is good; and when the two clamping arms are opened or clamped, the large-scale building materials placed on the bottom plate can be conveniently clamped and fixed, so that the stability of the large-scale building materials in the lifting process is improved and falling is avoided.

Description

Technical field [0001] The invention relates to the technical field of construction equipment, more specifically, it relates to a large-scale construction material lifting and transporting device. Background technique [0002] The product structure of a large-scale building material hoist used in construction sites. The hoist consists of running parts, driving devices, upper devices, middle casings, and lower devices. The running part is composed of a hopper and a sleeve roller chain. The driving device is an electric motor, which is composed of a reducer and a chain transmission. The driving device is divided into left and right installations, corresponding to the left and right installations of the hoist respectively. Bucket elevator is currently a relatively advanced and mature type of lifting equipment in China. It has been widely used to upgrade various large-scale building materials and is widely used in various industrial countries. The advantages of these equipment are t...

Problems solved by technology

The advantage of these devices is that the lifting range is wide, and the hoist has less requirements on the types and characteristics of large-scale building materials; and it can lift large-scale building materials of different sizes and large-scale building materials at higher temperatures, and has a large conveying capacity and a wide range of lifting volumes. Very large; long service life, low driving power, high lifting height, good sealing, less environmental pollution, good operational reliability, convenient operation and maintenance, less wearing parts, good rigidity of the whole machine, and high precision, but this type of lifting The disadvantage of the machine is that it is driven by steel strands or chains during the lifting process, lacks stability, is easy to swing left and right, and lacks the necessary platform for placing large building materials and a clamping mechanism for fixing large building materials. The safety performance is low. It is easy to fall, and the operation is more complicated
