Abstract

The present invention provides a multi-spindle trolley. It is characterized by that when number of pulley wheel spindles of the trolley is greater than 2 spindles, it is composed of two or more than two components and cross-beam or hanging ring or hanger frame connecting with lift hook or girder and connecting bar, etc. which are hinged mutually by means of upper and lower jointed shafts, and the pulley wheel spindles can be rotated along their inclined direction. Eachc omponent is composed of a pulley wheel spindle and 2-3 pulley-blocks and matched attachments of guard plate and partition board, etc.. Said invented product is simple in structure, and its operation is reliable.

Description

Multiple-spindle trolley

The utility model relates to crane hoisting equipment, and exactly, it is a kind of tackle block.

Existing tackle block, no matter the pulley number what, all only establish a shared sheave shaft, promptly be coaxial coaster.This coaxial coaster is formed polyspast, and when took turns wheel number 〉=4, if employing is run rope along wearing the traction of single flight head, wheel shaft can tilt, even the meeting knockdown, has a strong impact on lifting.Often need to adopt flower to wear, but flower is worn trouble, and because of flower wear for wear every wheel around, then run rope and go into groove and certainly lead to big drift angle, when two coaster spacings of polyspast hour, running rope can other strength.Therefore, hoisting height is restricted.

The technical solution of the utility model is achieved in that

Multiple-spindle trolley comprises corresponding accessories such as suspension ring, hanging axis, sheave shaft, pulley and backplate, dividing plate in the existing coaster, be characterized in: it by 2 or 2 with upper-part and crossbeam (or the suspension bracket of suspension ring or connecting shackle or hanging beam), connecting rod etc., form by the upper and lower twisted axis hinge joint of setting up, sheave shaft can change along its bevelled orientation.And each parts by a sheave shaft and 2 to 3 pulley assemblies, and annexes such as corresponding backplate, dividing plate form.The plane of the upper and lower twisted axis axial line decision of each parts is all parallel to each other, and the spacing of the extremely following twisted axis axial line of the last twisted axis axial line of each parts all equates.

Because on each parts, the constraint of following anchor point, between each pulley (being the neutral surface of race) all the time (when containing each pulley unbalance stress) parallel to each other, thereby the polyspast of forming with multiple-spindle trolley, the same with the polyspast of forming with coaxial coaster, it is neat to have row's rope, irrelevant advantage such as scratch, because when all not setting anchor point as if each parts, the slope of each sheave shaft, only determine by each pulley strained condition of this wheel shaft, and each parts all is provided with, during following anchor point, each sheave shaft slope all equates, and its absolute value is not when all setting anchor point, the minimum value of each parts wheel shaft slope absolute value, and be less than or equal to when all anchor point not being set down the maxim of each parts wheel shaft slope absolute value.Since upper and lower be hinged, sheave shaft can change along its bevelled orientation, because each parts pulley number is 2 to 3, thereby multiple-spindle trolley has the coaxial coaster of wheel number less (general 2 to 3 pulleys), no matter whether the single flight head draws, and all can need not the advantage that flower is worn along wearing normal operation work.The design of multiple-spindle trolley, manufacturing process are basic identical with design, the manufacturing process of existing coaxial coaster, because it just on existing coaster product basis, is set up upper and lower twisted axis device, and set up the pulley number of axle etc.Thereby design, make and also can adopt existing corresponding part Coefficient standard of coaxial coaster and technology.If like this, major part can utilize the frock of existing coaster product to produce, thereby the design of multiple-spindle trolley, makes and do not have difficulties.

Be illustrated below in conjunction with drawings and Examples:

Fig. 1 is one of the utility model embodiment---three 9 structural representations of taking turns coaster of suspension ring type.

Fig. 2 is the left TV structure scheme drawing of Fig. 1.

Attached Figure 1 and Figure 2, this suspension ring type multiple-spindle trolley is gone up hinged compositions such as 18,3 following twisted axis 16 of twisted axis and crossbeam 14, suspension ring 1, connecting rod 17 by three parts by 3.Each parts by 9,3 pulley assemblies 7 of a sheave shaft, and corresponding backplate 5, dividing plate 6 etc. constitute, hanging axis 4 and bolt 10 are worn connection up and down with backplate, dividing plate.Hanger on the hanging axis 8 is hinged with crossbeam 14 separately, forms three and goes up hinge 15, and crossbeam 14 is hinged with suspension ring 1, forms two hinges 13, that is is the suspension ring axles; It is hinged that bolt is used connecting rod 17 mutually separately, forms three down hinges 16.Wherein the axial line of the last twisted axis 15 of 3 parts to the following spacing of the axial line of twisted axis 16 all equates, and each parts are all parallel to each other with the plane that following twisted axis axial line determines by last twisted axis axial line.Owing to upper and lowerly be hinged, sheave shaft can change along its well azimuth.Part 3 is the tail ring, and part 2 is a hanging axis pad pipe, and part 11 is the bolting pad pipe.During work, this multiple-spindle trolley can guarantee when take turns pulley number 〉=4, but still need only suitable wear also normal operation.The utility model can be applicable on the coaster of various types.

Claims

1. multiple-spindle trolley, comprise suspension ring, hanging axis, sheave shaft, pulley and corresponding accessory in the existing coaster, it is characterized in that: the pulley number of axle 〉=2, it is by suspension bracket or the hanging beam and the connecting rod etc. of the parts more than 2 or 2 and crossbeam or suspension ring or connecting shackle, form by the upper and lower twisted axis hinge joint of setting up, sheave shaft can change along its bevelled orientation, each parts by a sheave shaft and 2 to 3 pulley assemblies, and annexes such as corresponding backplate, dividing plate constitute.

2. multiple-spindle trolley according to claim 1 is characterized in that: the plane of the upper and lower twisted axis axial line decision of each parts is all parallel to each other, and goes up twisted axis axial line to the spacing of twisted axis axial line down and all equate.
