Abstract

The utility model discloses a semi-enclosed strengthened pulley shield, which comprises a strengthening plate, side plates and a housing plate, wherein the strengthening plate is connected on the sideplates; the arc-shaped housing plate is arranged between the two side plates; the two side plates and the housing plate are integrated into a whole; and a yoke plate hole is formed on the housing plate. The pulley shield has the advantages that the backing boards, connecting bolts and fasteners thereof and the manufacturing procedures are reduced, material consumption is saved, and the cost is reduced; the yoke plate is not reburied to be punched, thereby enhancing the strength of the yoke plate; the integral structure is firm and durable with high resistance strength; and after the shield ismounted, the visual effect during pulley hoisting and hanging is good, and the overall appearance is aesthetic.

Description

Semi-enclosed heavier-duty pulley cover

Technical field

The utility model relates to a kind of pulley accessory of load hook, specifically is a kind of semi-enclosed heavier-duty pulley cover.

Background technology

Pulley on the suspension hook of lifting apparatus is to be used for changing suspension hook group vertical lift, and can form assembly pulley and reach the labour-saving purpose, during the suspension hook normal operation of existing lifting apparatus, the friction in the not high and yoke plate operational process causes pulley cover deformed damaged to the pulley cover because of self intensity, and the perforation connection structure on the yoke plate, cause the yoke plate strength reduction, make normal production work can not carry out its complicated integral structure, loaded down with trivial details, poor visual effect, consumptive material consumption is serious, the cost height.

Chinese patent CN 95210618.3 discloses a kind of " the suspension hook group of the totally-enclosed case of compound type ", comprise that suspension hook, pulley, pulley and axle all install in the compound type fully enclosed case of a column type, case is formed by three, the connection place of per two cases, the outside relies on flange to fix, and the outside is by the seam engagement.

Chinese patent CN 200620071580.4 discloses a kind of " but suspension hook wire rope pulley case of anti-attrition ", comprise pulley, sheave shaft and case, pulley sleeve is connected on the sheave shaft, sheave shaft is fixed on the case, case is semi-enclosed, form by side plate and cover plate, be the cover plate of arc between two blocks of side plates, connect for the catching groove location between side plate and the cover plate, side end has a plurality of bolts hole along circular arc, the bolt hole of biside plate is corresponding mutually, with elongated bolt, axle sleeve is housed on the bolt between the side plate.

The pulley case that two kinds of above-mentioned patents relate to also can't improve the intensity of cover plate, saves the consumption of consumptive material.

Summary of the invention

The purpose of this utility model provides a kind of saving consumptive material, the semi-enclosed heavier-duty pulley cover that bulk strength is high.

The utility model is achieved in that

A kind of semi-enclosed heavier-duty pulley cover comprises brace panel, side plate, cover plate, and described brace panel is connected on the side plate, is the cover plate of arc between two blocks of side plates, and described two blocks of side plates and cover plate are an integral body.

Has the yoke plate hole on the described cover plate.

The utlity model has following advantage:

1. reduced backing plate, tie bolt and fastener thereof, reduced manufacturing procedure, saved consumptive material, cost is reduced.

2. because of yoke plate need not punching, so improved the intensity of yoke plate.

3. integral structure is firmly solid, the power resistance strength height.

4. the pulley good visual effect behind this cover body is installed, and monnolithic case is attractive in appearance.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural front view of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the instance graph that the utility model is equipped with lifting hook pulley.

Fig. 4 is the lateral plan of Fig. 3.

Code name implication among the figure: 1-brace panel; The 2-side plate; The 3-cover plate; 4-yoke plate hole; The 5-yoke plate; 6-suspension hook horizontal stroke

The specific embodiment

Referring to Fig. 1, Fig. 2: this semi-enclosed heavier-duty pulley cover, comprise 1, two block of side plate 2 of brace panel (haftplatte), arc cover plate 3, brace panel (haftplatte) 1 (haftplatte) is used to increase thickness or screw thread, be welded on respectively on two blocks of side plates 2, be the cover plate 3 of arc between two blocks of side plates 2, two blocks of side plates 2 and cover plate 3 are an integral body, have on the cover plate 3 to be used for the yoke plate hole 4 that yoke plate penetrates.This pulley cover is because side plate 2 and cover plate 3 are an integral body, thus advantages of firm, the power resistance strength height, it is effective that after-vision is used in assembling, and monnolithic case is attractive in appearance.

Referring to Fig. 3, Fig. 4, the assembly pulley 9 of lifting apparatus is placed in this pulley cover with yoke plate 5 one ends that pass yoke plate hole 4, sheave shaft 8 passes in the hole of brace panel 1, assembly pulley 9 and yoke plate 5 are connected on the sheave shaft 8, the two ends of sheave shaft 8 are fixed on this pulley cover by the baffle plate 10 on the bonded assembly brace panel 1 on two blocks of side plates 2 respectively, outer yoke plate 5 one ends of this pulley cover connect suspension hook 7 with lifting beam with hook 6, because need not punching, yoke plate 5 is connected with this pulley cover, improved the intensity of yoke plate, the two ends of lifting beam with hook 6 are fixing by the baffle plate on the yoke plate 5 11 respectively.The utility model has reduced backing plate, tie bolt and fastener thereof, has reduced manufacturing procedure, has saved consumptive material, and cost price is reduced.The fixed sturcture of sheave shaft 8 of the present utility model and lifting beam with hook 6 and the structure of yoke plate 5 are not limit and foregoing description, sheave shaft 8 and lifting beam with hook 6 can also adopt the structure of pin fixing etc., if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies, then the utility model intention comprises these changes and modification interior.
