Abstract

A double-face display clasp scale with convenience for operation, safe and reliable work and accurate metering consists of a U-shaped upper frame (1), a U-shaped lower frame (3), a pressure sensor (8), a pulley component (9), hook-cross beam components (10), a left display (4) and a right display (7), wherein, the upper frame is in cross combination with the lower frame; the pressure sensor (8) is arranged at the bottom of the upper frame (1), while the pulley component (9) is arranged inside the circular hole positioned at the upper part of the upper frame (1); the hook-cross beam components (10) are arranged inside the circular holes positioned at the lower parts at both sides of the lower frame (3), while the left display (4) and the right display (7) are respectively arranged at the upper parts at both sides of the lower frame (3). The utility model is particularly suitable for cargo handling and metering, etc. at railway station, port, warehousing and transportation industry and industrial and mining enterprise.

Description

The double-sided display scale with hook head

Technical field

The utility model relates to a kind of weight-lifting equipment pulley dedicated balance, is meant a kind of two-sided direct demonstration weighing electronic steelyard especially.

Background technology

Loading and unloading on weight-lifting equipments such as hoisting crane, driving in the past, metering goods are directly to hang up electronic crane scale to load and unload, measure on the pulley suspension hook of this equipment, though easy to operate like this, but exist following disadvantage:

1. electronic crane scale hangs under the suspension hook, will reduce effective use height of loop wheel machine;

2. between whip-gin hook and goods, introduce the suspension link, increased the potential safety hazard factor;

3. electronic crane scale belongs to non-rigidity with assembly pulley and is connected, and has increased the rolling momentum of goods, the steelyard damage that easily is impacted.

Summary of the invention

The utility model will solve and directly hang up the electronic crane scale loading and unloading in the past on weight-lifting equipment pulley suspension hook, the metering goods causes loop wheel machine effectively to use highly minimizing, increase potential safety hazard, the problem that steelyard easily is impacted and damages, a kind of double-sided display scale with hook head of the present utility model is provided for this reason, this scale fuses steelyard and assembly pulley, having shortened its suspension height, eliminated turning joint, is a kind of compact conformation, convenient reading, direct demonstration electronic crane scale that measuring accuracy is high.

In order to address the above problem, its special character of the technical solution adopted in the utility model is made up of " U " shape upper spider, " U " shape lower bearing bracket, pressure sensor, pulley assembly, lifting beam with hook assembly and left telltale, right telltale, pressure sensor is installed in the bottom of upper spider, pulley assembly is installed in the circular hole on upper spider top, the lifting beam with hook assembly is installed in the circular hole of lower bearing bracket two side lower parts, and left telltale and right telltale are installed in the top of lower bearing bracket both sides respectively.

Described upper spider is preferably detachable structure, form by yoke plate and staged lower roof plate bolt together on yoke plate, the right olecranon formula on the left olecranon formula, lower bearing bracket also is preferably detachable structure, and by yoke plate under the left olecranon formula, yoke plate and staged upper plate bolt together form under the right olecranon formula.

Described upper spider and lower bearing bracket are " U " shape frame, the two combined crosswise.

The utility model adopts the great advantage of upper and lower frame decussate texture to be: can not destroy any parts of former weight-lifting equipment, and use operation very easy.As long as the utility model is replaced former hoisting crane running block, can carry out loading and unloading, the metering operation of goods.Therefore its structure is very compact, links into an integrated entity with weight-lifting equipment, has characteristics such as measuring accuracy height, safety are good, convenient reading, has improved work efficiency.

The specific embodiment

Specific embodiments of the present utility model such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, yoke plate 1-1 and 1-2 and staged lower roof plate 1-3 constitute " u " shape frame on two olecranon formulas, and bolt up is integral, and have formed upper spider 1.Same lower bearing bracket 3 has also that yoke plate 3-1 becomes " U " shape frame with 3-2 with staged upper plate 3-3 bolt up under two olecranon formulas.Upper and lower frame combined crosswise.At the bottom inside face of upper spider 1 pressure sensor 8 is installed, at the steel bowl 2 of the inside top face setting pressure sensor of lower bearing bracket 3, upper and lower two frames are intersected and are placed upside down, and have formed the load mechanism assembly.

1 liang of upper lateral part of upper spider has two circular holes, whip-gin assembly 9 can direct mount in the above.The circular hole of 3 liang of side lower parts of lower bearing bracket is used for installing lifting beam with hook assembly 10.Left side telltale 4 and right telltale 7 are installed in lower bearing bracket 3 both sides upper positions respectively.In addition, a limit shaft 6 is housed also on the lower bearing bracket, has limited the action radius of upper and lower frame.

Principle of work of the present utility model is such: cargo weight is delivered on the lower bearing bracket 3 by lifting beam with hook assembly 10, makes 3 pairs of pressure sensors of lower bearing bracket 8 produce pressure.Pressure sensor 8 is promptly exported corresponding analog voltage signal.This signal is after microcomputer system sampling, amplification, filtering, A/D conversion and data handing, and cargo weight is directly read from left telltale 4 and right telltale 7.The utility model also has safety detection and overload warning function, guaranteed the safety of cargo handing, metering overall process effectively.

The utlity model has the advantages such as easy to operate, safe and reliable, accurate measurement, particularly suitable In occasions such as the cargo handling of railway, harbour, accumulating and industrial and mining enterprises, meterings, be a kind of novel rising The heavy-duty machine Special-purpose lifting steelyard.
