Abstract

The invention discloses a double-pulley hoisting connecting device which comprises a lifting hook; a shaft fixedly connected with the lifting hook; a first shaft sleeve and a second shaft sleeve respectively sleeving the upper part and the lower part of the fixed shaft; a first base plate and a second base plate respectively fixed at two sides of the second shaft sleeve; a first supporting seat with the first base plate fixed at the bottom and the first shaft sleeve fixed at the side; a second supporting seat with the second base plate fixed at the bottom and the second shaft sleeve fixed at the side; a first pullet block rotatably connected with the first supporting seat; and a second pullet block rotatably connected with the second supporting seat. Kinetic friction of a plurality of mooring ropes is used instead of static friction of a single mooring rope, which reduces the pressure born by the mooring ropes and the wearing of the mooring ropes and the device as much as possible, and thus the application process is safer.

Description

A kind of sister block lifting connecting device
Technical field
The present invention relates to a kind of sister block lifting connecting device.
Background technology
Existing suspender for hoisting heavy comprises suspension hook, then directly link to each other with hawser by suspension hook, this suspender in use, hawser is comparatively serious with wearing and tearing between the suspension hook, the long-time use may cause the hawser fracture, safety misadventure occurs, demands improvement urgently.
Summary of the invention
Problem for the prior art existence, the object of the invention is to propose a kind of sister block lifting connecting device, the static friction that replaces single cable by the dynamic friction of adopting many hawsers, so that reduce the pressure-bearing of hawser and the wearing and tearing of hawser and equipment, thereby so that in use safer as far as possible.
For reaching this purpose, the present invention by the following technical solutions:
A kind of sister block lifting connecting device comprises suspension hook; Axle, the captive joint suspension hook; The first axle sleeve, the second axle sleeve are fixed by socket respectively axle top, bottom; The first base plate, the second base plate are separately fixed at the second axle sleeve both sides; The first supporting seat, the first base plate is fixed in its bottom, and its side is fixed the first axle sleeve; The second supporting seat, the second base plate is fixed in its bottom, and its side is fixed the first axle sleeve; The first assembly pulley is rotationally connected the first supporting seat; The second assembly pulley is rotationally connected the second supporting seat.The first axle sleeve and the second axle sleeve axle that is spirally connected.The first base plate and the second base plate second axle sleeve that is spirally connected.The first supporting seat be spirally connected the first base plate and the first axle sleeve.The second supporting seat be spirally connected the second base plate and the first axle sleeve.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The present invention replaces the static friction of single cable by the dynamic friction of adopting many hawsers, so that reduce the pressure-bearing of hawser and the wearing and tearing of hawser and equipment as far as possible, thus so that in use safer.
Description of drawings
Fig. 1 is the integral structure schematic diagram of the embodiment of the invention 1:
Wherein: 1, suspension hook; 21, the first base plate; 22, the second base plate; 3, the first axle sleeve; 4
1, the first supporting seat; 42, the second supporting seat; 5, axle; 61, the first assembly pulley; 62, the second assembly pulley; 7, the second axle sleeve.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment:
Embodiment 1
Propose a kind of sister block lifting connecting device, comprise suspension hook 1; Axle 5, captive joint suspension hook 1; The first axle sleeve 3, the second axle sleeve 7 are fixed by socket respectively axle 5 tops, bottom; The first base plate 21, the second base plate 22 are separately fixed at the second axle sleeve 7 both sides; The first supporting seat 41, the first base plate 21 is fixed in its bottom, and its side is fixed the first axle sleeve 3; The second supporting seat 42, the second base plate 22 is fixed in its bottom, and its side is fixed the first axle sleeve 3; The first assembly pulley 61 is rotationally connected the first supporting seat 41; The second assembly pulley 62 is rotationally connected the second supporting seat 42.The first axle sleeve 3 and the second axle sleeve 7 axle 5 that is spirally connected.The first base plate 21 and the second base plate 22 second axle sleeve 7 that is spirally connected.The first supporting seat 41 be spirally connected the first base plate 21 and the first axle sleeve 3.The second supporting seat 42 be spirally connected the second base plate 22 and the first axle sleeve 3.
By making hawser cooperate the first assembly pulley 61, the second assembly pulley 62, make and spurring the first assembly pulley 61 by hawser, during the second assembly pulley 62, with the first assembly pulley 61, the second assembly pulley 62 uses as movable pulley, thereby so that at pulling the first assembly pulley 61, in the process that the second assembly pulley 62 rises, make the first assembly pulley 61, cliding friction between the second assembly pulley 62 replaces static friction, make hawser and the first assembly pulley 61, wearing and tearing between the second assembly pulley 62 are minimum, to guarantee safety, in addition, owing to comprising the first assembly pulley 61 and the second assembly pulley 62 in this device, the pulling force that can guarantee weight in the process of drawing the lift heavy thing is shared by four hawsers, so that hawser is difficult for fracture, and can make weight more stable in drawing the process of hanging, be difficult for occuring safety misadventure.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
