Abstract

A simple folding type crane boom is composed of three parts including a crane boom cross beam, a crane boom supporting rod and a crane boom chassis. Due to the sectional type connecting structure of the simple folding type crane boom, the simple folding type crane boom can be folded to be in a long strip shape, then the crane boom cross beam and the crane boom supporting rod are stored in the crane boom chassis, market requirements are met, and use prospects are wider.

Description

Simple folding crane arm

Technical field

The utility model relates to a kind of simple folding crane arm.Particularly removable folding simple type crane arm, by the sectional type connection structure of crane arm, can be folded into a strip, is accommodated on crane arm chassis, does not take up room.

Background technology

At present, known hoisting crane belongs to the one of elevator machinery, a kind of circulation, the machinery of intermittent moment, a working cycle comprises: load-engaging device is mentioned article from getting thing, then be moved horizontally to appointed place and fall article, then carry out counter motion, make load-engaging device reposition, to circulate next time, need hoisting device and hook block device to transport building materials or equipment at construction site, general hoisting crane is big machinery, self structure is just subject to the restriction of camp site, cannot reach the requirement in construction, in small-sized indoor storage environment, traditional hoisting crane is too huge and complicated, be not easy to operation and lay.The utility model is a kind of simple folding crane arm, by the sectional type connection structure of crane arm, can be folded into a strip, be accommodated on crane arm chassis, this innovative design is a kind of competitive edge greatly in commercial operation is promoted, and valuable is that this know-why is simple, and its to establish scheme reasonable and practical, in thinking, break down the conventions, thereby brought new technological revolution.

Summary of the invention

In order to overcome the defect that traditional support tube structure exists on running is constructed at present, utility model provides a kind of simple folding crane arm, by the sectional type connection structure of crane arm, can be folded into a strip, be accommodated on crane arm chassis, the product of innovating by technique can better be used and be promoted in business and field of engineering technology.

The utility model solves the technical scheme that its technical matters adopts, it is characterized in that, crane arm is made up of three parts, comprise crane arm crossbeam, crane arm pole, crane arm chassis, wherein crane arm crossbeam and crane arm pole are all the structural slab of rectangle, crane arm crossbeam and crane arm pole junction form the point of connection of rectangle, on crane arm crossbeam and crane arm pole, there is corresponding strip shape draw-in groove, by the point of connection rotary connection of rectangle, coordinate strip shape draw-in groove fixed position, crane arm pole is inner is used for receiving crane arm crossbeam for engraved structure, make the folding smooth safety of hoisting arm structure, at the top of crane arm crossbeam connection structure driving band, in structure driven band, connect the cable wire that draws hook, junction between crane arm pole and crane arm chassis, also adopt the point of connection structure of rectangle, bottom, crane arm chassis connects row's pulley, can make crane arm move by pulley, realize the actual utility of this simple folding crane arm.Crane arm chassis forms loading surface simultaneously, in the goods of fishing, also can convey goods, and in the time of daily storage, by the sectional type connection structure of crane arm, can be folded into a strip, is accommodated on crane arm chassis, does not take up room.This simple folding pipe boom is more applicable for the control application on engineering technology, has expanded range of use, thereby and also can use in more areas technique innovation to bring more income.

The beneficial effects of the utility model are, in actual utilization process, this utility model provides a kind of simple folding crane arm, by the sectional type connection structure of crane arm, can be folded into a strip, be accommodated on crane arm chassis, promoted the physical function of this simple folding crane arm.

Accompanying drawing explanation

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

Fig. 1 is principle of design figure of the present utility model.

1. simple folding crane arms in figure, 2. weighing arm crossbeam, 3. crane arm pole, 4. crane arm chassis, the 5. point of connection of rectangle, 6. strip shape draw-in groove, 7. structure driven band, 8. hook, 9. cable wire, 10. pulley.

The specific embodiment

In Fig. 1, simple folding crane arm 1 crane arm is made up of three parts, comprise crane arm crossbeam 2, crane arm pole 3, crane arm chassis 4, wherein crane arm crossbeam 2 and crane arm pole 3 are all the structural slab of rectangle, crane arm crossbeam 2 and crane arm pole 3 junctions form the point of connection 5 of rectangle, on crane arm crossbeam 2 and crane arm pole 3, there is corresponding strip shape draw-in groove 6, by point of connection 5 rotary connections of rectangle, coordinate strip shape draw-in groove 6 fixed positions, crane arm pole 3 is inner is used for receiving crane arm crossbeam 2 for engraved structure, make the folding smooth safety of hoisting arm structure, at the top of crane arm crossbeam 2 connection structure driving band 7, the cable wire 9 of hook 8 draws in the interior company of structure driven band 7, junction between crane arm pole 3 and crane arm chassis 4, also adopt the point of connection structure 5 of rectangle, 4 bottoms, crane arm chassis connect row's pulley 10, can make crane arm move by pulley 10, realize the valid function of simple folding crane arm 1.

Claims
