Abstract

The utility model relates to hoisting equipment, particularly to electric low-velocity hoisting equipment for installing a hoist during the wine construction process. The hoisting equipment comprises a fixing A-bracket on two sides of which an electric motor and a reducer connected with a main shaft are installed symmetrically, a stirrup is used for hanging two chain blocks at the top part of the A-bracket, a movable pulley for hanging the hoisted heavy objects is connected between two chain blocks through a hand zipper, and the two chain blocks are connected with the output chain wheel of the reducer through a chain. The utility model has the advantages that the structure is simple, the rising and falling operation is steady, and the physical exertion and the labor intensity of the worker can be reduced.

Description

Electronic low speed lifting appliance

Technical field

The utility model relates to a kind of lifting appliance, specifically is to be used for the ore deposit to build a kind of electronic low speed lifting appliance that the gig use is installed in construction.

Background technology

It is very arduous that execution conditions are built in the ore deposit, and the camp site does not have large-scale lifting appliance, the installation of preparation of construction, particularly hoist installation, and nearly 40 tons of its main shaft device, lifting is difficult especially during installation.Adopt Shears to take root during conventional mounting, generally select for use two groups of 20T chain blocks to carry out the manpower lifting.Need 10～12 staff to pull and rise and fall, one group of specified power of pulling reaches 828N, and two groups reach 1656N, and everyone is more than the average out to 150N, and labor strength is big, and speed is slow.

Summary of the invention

The utility model provides a kind of electronic low speed lifting appliance, utilizes the power drive principle, relies on the manpower frame, and chain block has solved the on-the-spot drawback that needs a large amount of manpower and materials of lifting by crane of prior art, has saved the set-up time.

The utility model is realized with following technical scheme: a kind of electronic low speed lifting appliance, it is characterized in that, comprise the fixing Shears of using, the reductor that one electrical motor respectively is installed and connects in the bilateral symmetry of Shears with motor main shaft, hang two chain blocks at the Shears top with a stirrup, connect a movable pulley that is used to hang by hoisting heavy by pulling chain between two chain blocks, two chain blocks are connected with the output chain gear of reductor by chain.

Start the slide fastener motion by control motor rotating band, two motors can be synchronously or asynchronous starting with stop, assurance is risen and fallen steadily by the hoisting heavy two ends, maintenance in allowed band, is prevented that the end from coming off, and causes mechanical falling accident by the hoisting heavy levelness.See accompanying drawing one, macro-axis rises and falls only needs 4～5 people, and the special messenger commander saves the labour power of half.

The beneficial effects of the utility model are: simple in structure, rise and fall steadily, and reduced workman's physical demands and labour intensity.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is the utility model structural representation.

Among the figure: 1, electrical motor, 2, sprocket wheel, 3, chain, 4, reductor, 5, chain block, 6, Shears, 7, main shaft of hoister, 8, movable pulley, 9, stirrup, 10, pull chain.

The specific embodiment

Embodiment as shown in drawings, the lifting main shaft of hoister was used when electronic low speed lifting appliance was used for lifting by crane mine construction construction installation gig. two electrical motors 1 are arranged, with two reductors 4 of electrical motor 1 rotating shaft bonded assembly, hang two 620T chain blocks 5 with stirrup 9 on the Shears top, 5 of two 620T chain blocks are hung a movable pulley 8 with pulling chain 10, the sprocket wheel 2 of two reductors 4 is started to draw cucurbit 5 rotations to be used to lift by crane main shaft of hoister 7. electrical motors by chain 3 and two 620T chain block 5 connecting bands respectively and is selected the 1.5KW four-stage motor, slow down by 40 grades of worm type of reduction gearings 2, the mouth sprocket wheel 2 of reductor drives chain block 5 by chain and rotates, chain block 5 drives movable pulleys 8 and rises and falls and pull chain 10 speed with lifting main shaft of hoister 7. and can reach 0.5m/s by pulling chain 10, guarantee evenly to rise and fall at a slow speed, but the lifting unit that two cover symmetries are installed can be synchronously also asynchronous starting with stop, carrying out the inching of lifting speed.

This device is across the weight both sides of being lifted by crane at quilt, start the slide fastener motion by control motor rotating band, slide fastener speed only is 0.5m/s, but two motor asynchronous startings with stop, rise and fall steadily in assurance main shaft two ends, keep the main shaft levelness in allowed band, prevent that the end from coming off, and causes mechanical falling accident.

Claims (1)

1. electronic low speed lifting appliance, it is characterized in that, comprise fixing with Shears (6), the reductor (4) that one electrical motor (1) respectively is installed and connects in the bilateral symmetry of Shears with motor main shaft, hang two chain blocks (5) at the Shears top with a stirrup (9), be used to hang by the movable pulley of hoisting heavy (8) by pulling chain (10) connection one between two chain blocks (5), two chain blocks (5) are connected with the mouth sprocket wheel (2) of reductor (4) by chain (3).
