Abstract
The utility model relates to a double-worm hoisting device which is composed of a worm 1, a left worm wheel 2, a left worm wheel shaft 3, a left roller 4, a steel wire rope 5, a right worm wheel 6, a right worm wheel shaft 7, a right roller 8, a box body 9, a movable pulley 10, a pin roll 11, a lifting hook 12, a left worm wheel shaft end support 13 and a right worm wheel shaft end support 14. The double-worm hoisting device is characterized in that the worm 1 is vertically mounted in the middle of the box body 9, the left worm wheel shaft 3 and the left worm wheel 2 are arranged on the left side of the box body 9, the right worm wheel shaft 7 and the right worm wheel 6 are arranged on the right side of the box body 9, the extending end of the left worm wheel shaft 3 is provided with the left roller 4 and the left worm wheel shaft end support 13, the extending end of the right worm wheel shaft 7 is provided with the right roller 8 and the right worm wheel shaft end support 14, the two ends of the steel wire rope 5 are wound on the left roller 4 and the right roller 8 respectively in the opposite directions, because when the worm 1 rotates, the left worm wheel 2 and the right worm wheel 6 rotate in the opposite directions, the middle of the steel wire rope 5 winds across the movable pulley 10, and the movable pulley 10 is provided with the pin roll 11 and the lifting hook 12.
Description
Technical field
The utility model relates to a kind of lifting bont, is a kind of bont of lifting based on twin worm specifically.
Background technology
Usually the lifting bont need to solve two subject matters, the one, hoisting force, the 2nd, braking force, because worm drive has auto-lock function, so the driving system of Chang Zuowei lifting, hoisting device, but worm geared worm shaft rigidity is not high, if improve the lifting hoisting capacity, be subject to the restriction of rigidity, therefore need to overcome the low shortcoming of rigidity.
Summary of the invention
The purpose of this utility model is to provide a kind of bont of lifting based on twin worm.
the technical solution of the utility model: this device is supported (14) and is formed by worm screw (1), left worm gear (2), left worm-wheel shaft (3), roll left cylinder (4), steel rope (5), right worm gear (6), right worm-wheel shaft (7), right cylinder (8), casing (9), movable pulley (10), bearing pin (11), suspension hook (12), left worm-wheel shaft axle head support (13) and right worm-wheel shaft axle head, it is characterized in that worm screw (1) vertically is arranged on the centre of casing (9), the right and left is installed respectively left worm-wheel shaft (3) and left worm gear (2) and right worm-wheel shaft (7) and right worm gear (6), external part at left worm-wheel shaft (3) is equipped with roll left cylinder (4) and left worm-wheel shaft axle head support (13), external part at right worm-wheel shaft (7) is equipped with the right worm-wheel shaft axle head support of right cylinder (8) (14), the two ends of steel rope (5) are respectively oppositely on roll left cylinder (4) and right cylinder (8), movable pulley (10) is walked around in the centre of steel rope (5), bearing pin (11) and suspension hook (12) are housed on movable pulley (10).
Beneficial effect: this is simple in structure, and existing worm geared auto-lock function can overcome again the problem of worm shaft poor rigidity.

The specific embodiment
According to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, specific embodiments of the present utility model is described in detail.
This device supports 14 by worm screw 1, left worm gear 2, left worm-wheel shaft 3, the cylinder 4 that rolls left, steel rope 5, right worm gear 6, right worm-wheel shaft 7, right cylinder 8, casing 9, movable pulley 10, bearing pin 11, suspension hook 12, the support 13 of left worm-wheel shaft axle head and right worm-wheel shaft axle head and forms; It is characterized in that worm screw 1 vertically is arranged on the centre of casing 9, the right and left is installed respectively left worm-wheel shaft 3 and left worm gear 2 and right worm-wheel shaft 7 and right worm gear 6, has so just overcome the low defect of worm drive worm shaft rigidity; External part at left worm-wheel shaft 3 is equipped with roll left cylinder 4 and left worm-wheel shaft axle head support 13, at the external part of right worm-wheel shaft 7, the right worm-wheel shaft axle head of right cylinder 8 is installed and supports 14, installs left worm-wheel shaft axle head support 13 and right worm-wheel shaft axle head support 14 be in order to improve the rigidity of left worm-wheel shaft 3 and right worm-wheel shaft 7; The two ends of steel rope 5 are respectively oppositely on roll left cylinder 4 and right cylinder 8, because worm screw 1 is while rotating, and left worm gear 2 and right worm gear 6 backward rotation, movable pulley 10 is walked around in the centre of steel rope 5, and bearing pin 11 and suspension hook 12 are housed on movable pulley 10; Driving power is input to this lifting bont by the top of worm screw 1.
When cargo lifting (as Fig. 3), roll left cylinder 4 and right cylinder 8 are around D to rotation, and steel rope 5 drives movable pulley 10, bearing pin 11 and suspension hook 12 upward movements; When goods descended, roll left cylinder 4 and right cylinder 8 were around C to rotation, and steel rope 5 drives movable pulley 10, bearing pin 11 and suspension hook 12 and moves downward.
