Abstract

The utility model relates to a device used for lifting a derrick hanger in construction. The utility model uses a motor as dynamic force. After the force output through a speed reducing add-forced structure passes through a steel cable and an accessory, the force acts on a hoisting cantilever. The cantilever can move horizontally. The utility model alters and gets rid of the operating mode that the traditional derrick hanger needs two persons to drag the steel cable, wherein, one person is on the derrick hanger and the other person is under the derrick hanger. After the device is installed on the derrick hanger, the derrick hanger is similar to a tower crane and has two functions of vertical movement and horizontal movement.

Description

Lifting cantilever horizontal motion machine

The utility model is a kind of device that is mainly used in building well cabinet frame hoisting hook, also can be used on other lifting field.

At present in building lifting field, three kinds of weight-lifting equipments commonly used are arranged, that is: tower crane, gauntry crane, derrick hang, except that expensive tower crane has the function of lifting object horizontal motion, other two kinds are not all had, and cheap derrick is hung on our the domestic building ground, make with the most usely, it is the very high equipment of a kind of cost performance.But its blemish in an otherwise perfect thing is that hanging piece is moved horizontally, dangerous.It all is like this that the derrick that we have investigated each building ground, the whole nation hangs, so this utility model is a kind of brand new product.

The purpose of this utility model provides and a kind ofly makes traditional derrick suspender have own level to move the function of lift heavy thing.Want safe, convenient, functional, cheap simultaneously, hang with derrick and be complementary with cheapness.

The utility model is achieved in that the operator sends the running of instruction rear motor, and the steamboat on the motor drives the bull wheel on the slowing-down structure by driving band, and the power of the back output of slowing down by steel cable, in the lifting cantilever, rotates its left side (right side) by the runner directional tagging.Hoisting heavy on the cantilever has just been realized horizontal motion so.The electric control circuit of this utility model can be by common button, adds that cable realized line control, also can use controlled in wireless, and we have designed a kind of inexpensive drag-line ratchet step switch, also easily, safety.For the needs of special of building site lifting need with other.We have designed a kind of easy taking off again and have buckled assembly.This utility model can have all kinds, and keystone configuration is all similar, has only main slowing-down structure that bigger variation is arranged.We have conceived multiple scheme to slowing-down structure, can be made of worm screw, worm gear and shift fork, also can constitute by miniature gears and big ring-like tooth bar, and their better performances, but the machine up complexity is on the high side.Can also constitute by screw rod, nut, directly push away the product cantilever by screw rod.This cost is very low, but operating angle is less than 180 degree.This several principle is all very simple, and we are several with regard to not describing and illustrate this in detail as space is limited.Below two kinds be that performance is good, but cheap structure: A type, main slowing-down structure is to be made of filament threading wheel etc., filament threading wheel is that two ends are big, there is the garden wheel of lonely shape concave ring groove the centre, the power of filament threading wheel output drags a lifting cantilever left side (right side) and rotates, just horizontal motion after being led by runner by steel cable.Guiding wheel seat or other place need install extension spring additional, and steel cable is tightened constantly.In order to enlarge operating angle, on the derrick angle of cantilever inboard, also need adorn a top and open wheel, like this, effectively operating angle can expand 260 degree to by 170 original degree.Type B, main slowing-down structure are screw rod and nut, and this nut is a kind of special nut of thickening that defeated power structure is arranged in the side, and the power of nut output also is after being led by runner by steel cable, to drag a lifting cantilever left side (right side) and rotate.Still equally add the top with the A type and open wheel, angle is enlarged, effective operating angle of Type B is 230 degree.

The utility model can arbitrarily be controlled the skyborne position of lifting cantilever because of the operator, so it thoroughly changes and has discarded in the past that derrick hangs, always need upper and lower two people to drag the operating mode of hauling rope, economize people, laborsaving and safety like this, no longer have the danger of dragging thing to slip to fall down from the building.Save two and fall the hauling rope of mixing, can reduce the high-altitude and fall and mix down plank, the excellent worry of fragment of brick.Also have very big characteristics to be: floor area not for the overlooking building in the city of land for building anxiety, provides convenience.The physical construction of this device is to form with general part, and machine up is simple, and expense is cheap, and performance is good equally, and its overall price is reperused inferior identical with cheap derrick.

Fig. 1, Fig. 2 are respectively A type of the present utility model, Type B structural representation birds-eye view, Fig. 1 ', Fig. 2 ' be respectively the A type,, the whole diagrammatic side view of Type B.

(1) electrical motor (2) small belt pulley (3) big belt pulley (4) screw rod (5) exert oneself filament threading wheel (6) steel rope (7) runner (8) lifting cantilever (9) top of nut (5 ') of exerting oneself is opened wheel (10) well cabinet frame angle steel (11) motor control switch (12) and is taken off and buckle assembly (13) nail (14) limit lever (15) lever connection cord of threading off.

Be described in further detail below in conjunction with accompanying drawing: (as Fig. 2) hangs the height of needs when hoisting heavy, the operator sends instruction, motor (1) rotates, and steamboat (2) drives people's wheel (3) by driving band and rotates, and screw rod (4) also together rotates, nut (5) is produced to be moved axially, taking off on the nut (5) buckles the also same moved further of steel cable of assembly chucking, by after runner (7) guiding, drags lifting cantilever (a 8) left side (right side) and rotates again, hoisting heavy on cantilever is also along with rotation, and the generation horizontal motion.During to the position that needs, the operator sends instruction, motor (1) stall, and the lift heavy thing stops horizontal motion, and hanging thing then can slowly drop to the position that needs with the winch steel cable.If operation makes mistakes, and when moving to end position, can promote limit lever (14), makes motor (1) stall, hoisting heavy just can not overstep the extreme limit the position.Wheel (9) is opened on the top of this device unique design makes operating angle be expanded to more than 230 degree by 170 degree, and does not have the dead angle.Thereby can be fit to the use of various building ground.

Claims (1)

1, a kind of derrick resuspended arm horizontal motion machine of slinging, by the steamboat (2) on the motor (1) through driving band, drive the bull wheel (3) on the main slowing-down structure, the power of exporting by nut (5) [or filament threading wheel (5 ')] after slowing down, by steel cable (6), behind runner (7) guiding and top wheel (9) corner, act on lifting cantilever (8), it is moved horizontally, it is characterized in that:

A, this utility model are on derrick (10) angle of cantilever (8) inboard, and customized design is opened wheel (9) with having installed to push up;

B, this utility model customized design and installed, two ends are big, and there is the filament threading wheel (5 ') of lonely type concave ring groove the centre, or there is the special nut of thickening (5) of defeated power structure the side.
