Abstract

The invention discloses a hoisting tackle and belongs to the technical field of hoisting facilities. The hoisting tackle comprises an upper pulley block and a lower pulley block, wherein the upper pulley block comprises an upper pulley yoke, an upper pulley yoke cover plate, a first upper pulley and a second upper pulley; and the lower pulley block comprises a lower pulley yoke, a lower pulley yoke cover plate, a first lower pulley and a second lower pulley. The hoisting tackle is characterized by also comprising a rope-way random conversion device. When the rope-way random conversion device is connected onto the upper pulley yoke and corresponds between the first upper pulley and the second upper pulley, the rope way of the rope passing through the upper pulley block and the lower pulley block is changed into two rope ways, so that light objects can be fast lifted; and when the random conversion device is connected on the lower pulley yoke and corresponds between the first upper pulley and the second upper pulley, the rope way of the rope passing through the upper pulley block and the lower pulley block is changed into four rope ways, so that heavy objects can be lifted slowly. The hoisting tackle disclosed by the invention has the advantages that the construction operation efficiency is increased, and the requirement for slow-speed and labor-saving lifting of large-mass objects can be met.

Description

Tackle block

Technical field

The invention belongs to technical field of hoisting facility, be specifically related to a kind of tackle block, be suitable for power construction operation occasion

Background technology

tackle block is no lack of in disclosed Chinese patent document and is seen in, " pulley hangs " that representative type such as Granted publication CN87201473U recommend, and this patent scheme is suitable for the weight handling of resident's floor; Shortcoming that the three pulley groups that " a kind of three pulley hoisting coasters " that CN221686406U provides, this patent scheme have overcome parallel arranged in the prior art interfere between many steel ropes when lifting and volume and the weight that has reduced device.More representative type such as CN201367332Y " the variable gin wheel group " introduced; This patent scheme proposes to the weight of power construction operation occasion lifting tower body and cross-arm etc.; And rope is changed between assembly pulley; Specifically can should this patent scheme can embody the capable technique effect of its Instructions Page 2 8-14 referring to 3 pages of eighth rows of Instructions Page 2 last column to the of this patent.

such as industry knowledge, using the occasion of tackle block, have two kinds of situations usually: the one, it is big to hold the weight of hanging object; The 2nd, it is lighter relatively to hold the weight of object that hangs; If therefore the rope of tackle block and the matching relationship between the assembly pulley adopt the mode of promptly making no exception with a kind of mode; When the lightweight object of handling, can not produce the low-hanging fruit of workmen's expectation so, thereby influence operating efficiency.Because the rope of the tackle block in the prior art and the relation between the assembly pulley are to make up according to the heavy object of hoisting weight, and in use can not randomly changing.In the technical scheme of the CN201367332Y that mentions in the above; Though can the relation between rope and the assembly pulley be changed; But need for a change the teachings of organic conversion between the object that how to make the handling Heavy Weight and the lightweight object of handling is not instructed or hinted to wire rope handling mode, especially this patent scheme by power construction operating personnel people owing to lack structural reasonableness.Because this patent scheme can't be transferred on the guide roller frame that is disposed at top and pulley that be positioned at the centre on the guide roller frame of bottom.

In view of above-mentioned prior art, the applicant has done useful design, and the technical scheme that will introduce below produces under this background

Summary of the invention

task of the present invention is to provide a kind of can change the relation between rope and the assembly pulley according to being changed by the weight of the weight of handling and to use embodiment slow and laborsaving when suspended object body weight speed per hour degree randomly, and speed is fast and improve the tackle block of operating efficiency when hanging object is light.

task of the present invention is accomplished like this; A kind of tackle block; Comprise top sheave group and downslide wheels, the top sheave group comprises top sheave frame, top sheave frame cover plate, first top sheave and second top sheave, and top sheave frame cover plate cooperates face-to-face with the top sheave frame and fixes with the top sheave frame; First top sheave is arranged on the side of top sheave frame towards top sheave frame cover plate rotationally; And be positioned at an end of top sheave frame, second top sheave is arranged on the top sheave frame rotationally equally towards a side of top sheave frame cover plate, and is positioned at the other end of top sheave frame; Wherein: be provided with a upper lift ring at the middle part of the length direction of top sheave frame and above being positioned at, and be provided with a lanyard seat corresponding to the position below said first top sheave; The downslide wheels comprise downslide wheel carrier, downslide wheel carrier cover plate, first lower sheave and second lower sheave; Downslide wheel carrier cover plate cooperates face-to-face with the downslide wheel carrier and fixes with the downslide wheel carrier; First lower sheave is arranged on the side of downslide wheel carrier towards downslide wheel carrier cover plate rotationally; And an end that is positioned at the downslide wheel carrier is corresponding with described first top sheave, and second lower sheave is arranged on the downslide wheel carrier rotationally equally towards a side of downslide wheel carrier cover plate, and is positioned at the other end of downslide wheel carrier; Corresponding with described second top sheave; Wherein, be provided with a lower lift ring, be characterised in that: also include a rope race stochastic transformation device at the middle part of the length direction of downslide wheel carrier and below being positioned at; When this stochastic transformation device is connected on the described top sheave frame and between corresponding to said first, second top sheave the time, makes rope race by way of the rope of top sheave group and downslide wheels become two rope races and use and make the lightweight object fast lifting; And be connected on the described downslide wheel carrier and between corresponding to described first, second lower sheave the time when this stochastic transformation device, then become four rope races and use heavy object is promoted slowly by way of the rope race of the rope of top sheave group and downslide wheels.
