CN2199182Y - Simple lifter - Google Patents

Abstract

The utility model relates to a simple lifter which solves the lifting problem of a device at a low-lying operating point without a highway. A triangular frame arranged on a fixed upright post of the operating point is used, and the end of a cross beam 8 of the triangular frame is hinged with a pulley block 10, and a big hook 11 is hung by a wire rope round the pulley block; both ends of a vertical shaft 4 of the triangular frame are provided with bearings (2 and 5), a clamp 7 clamped on a fixed piece, and an upper and a lower guiding pulleys (1 and 6). The wire rope is tied on a roller on a hand pushing winch 13 by the two guiding pulleys. The big hook lifts the device with the rotation of the roller, and the device is lifted out by manually rotating the triangular frame, and the lifter is disassembled and is pushed away along with the winch after the lifter is used. The utility model is suitable for the lifting operation of dispersive lifting operating points.

Description

Simple lifter

The utility model relates to a kind of lifting operation machine, can be by the simple and easy hoisting machine of artificial migration.

Crane is the lifting operation machine, the manoevreability height, also relatively flexibly.But the employing crane operation needs highway and more solid operation ground, and it is many to be particularly suitable for work members quantity, and relatively more concentrated heavy wares.For open-air working in dispersion point, what each setting need lift has only one, two; Setting is located in the low-lying highway that do not have again simultaneously, adopts crane just not too suitable under this condition, and is simultaneously also uneconomical.

It is not enough that the purpose of this utility model is to avoid in the above-mentioned present technology, and provide a kind of be suitable for open-air working in dispersion point can be by the simple and easy hoisting machine of artificial migration.

The purpose of this utility model can reach by the following technical programs: hang the assembly pulley hinge joint of hook on crossbeam 8 ends of spider by steel rope, bearing is equipped with at the two ends of the vertical shaft 4 of spider, be stuck in the clamp of connecting element and leading sheave up and down, steel rope is fastened on the cylinder on the hand push winch through two leading sheaves.

Above-mentionedly adopt telescopic crossbeam, the middle part is a sleeve, the inserted link of useful bearing pin location, two ends; The arc parallel with vertical shaft can be housed between last lower clip; Cylinder can adopt motorized pulleys.

The utility model can have following advantage than above-mentioned prior art: this hoisting machine is light to be contained on the hand push winch, and can enter does not have highway and low-level bog setting, is fit to the open-air lifting operation that disperses; Extremely disperse as oil field pumping well, the well point that has does not have highway well location condition bad, and these wells need hanging device in maintenance process, adopts this hoisting machine just more convenient, and is simultaneously very economical yet.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By shown in Figure 1, hung hook 11 through unsettled assembly pulley 10 by steel rope 12; Wherein assembly pulley 10 hinge joints are on crossbeam 8 ends of spider, bearing (2 is equipped with at the two ends of the vertical shaft 4 of spider, 5), be stuck in clamp 7 and upper and lower leading sheave (1,6) on the setting connecting element (column), the steel rope of suspention hook is fastened on the cylinder on the hand push winch 13 through two leading sheaves.

Can adopt telescopic crossbeam 8, can be inclined upwardly during installation, the crossbeam middle part is a sleeve, and the inserted link of useful bearing pin 9 location, two ends extends as required.Upper and lower clamp can be welded on the ipsilateral of upper and lower bearing seat, so that be stuck on the fixing column of setting, spider erect can be carried out lifting operation.Following leading sheave 6 can be welded under the step by support 14, and last leading sheave is fixed on the crossbeam, by support pulley is stood on the vertical shaft top; Upper and lower bearing seat and vertical shaft have the coaxial line through hole, and the steel wire penetrating through hole is again on leading sheave.General job point all has power supply, and cylinder can adopt motorized pulleys by driven by motor on the hand push winch.Spider is rotatable, depends on the vertical rod rotation that clamp blocks for making spider, can be welded with the arc andante 3 parallel with vertical shaft between upper and lower clamp.

Claims (4)

1, a kind of simple and easy hoisting machine, it has hook (11) to be hung on the assembly pulley (10) by steel rope (12), it is characterized in that: assembly pulley (10) links on crossbeam (8) end of spider, bearing (2,5) is equipped with at the two ends of the vertical shaft of spider (4), be stuck in clamp (7) and upper and lower leading sheave (1,6) on the setting connecting element, steel rope is fastened on the cylinder on the hand push winch (13) through two leading sheaves.

2, hoisting machine according to claim 1 is characterized in that: can adopt telescopic crossbeam (8), the middle part is a sleeve, the inserted link of useful bearing pin location, two ends.
