Abstract
The utility model relates to a crane. A frame is connected with a chassis of the crane, and a transmission shaft is arranged in the frame. A driven gear, a ratchet wheel and a brake are arranged on the transmission shaft, and reels are arranged on both ends of the transmission shaft connected with the frame through rolling bearings on both ends. A motor is arranged on the frame, and is engaged and connected with the driven gear through a driving gear, and a ratchet pawl matched with the ratchet wheel is arranged on the frame corresponding to one side of the ratchet wheel. Both sides of the front end of the frame are hinged with two suspended arms, and respective support bars are connected with the middles of the two suspended arms. Two suspended ropes are respectively connected with the reels at both ends of the transmission shaft, and round a pulley arranged in the corresponding position of the frame and pulleys on the front ends of the two suspended arms to be connected with both ends of a suspended basket.
Description
The utility model relates to a kind of crane.
Existing crane all is lifting heavy mail, big part, but just inapplicable for the object handling on the general goods yard.The one, the space is insufficient, and the 2nd, expense is uneconomical.
The utility model purpose is exactly in order to address the above problem, and a kind of wide application is provided, and uses Simple crane flexibly.
Technical solution of the present utility model:
A kind of Simple crane, it is characterized in that it is connected with framework 2 on chassis 1, be provided with transmission shaft 3 in this framework 2, on this transmission shaft 3 driven gear 4 is housed, ratchet 5 and drg 6, its two ends are provided with reel 7, it is connected with framework 2 by the rolling bearing 8 of two ends, also be provided with motor 9 on the framework 2, motor 9 is connected with a joggle by driving gear 10 and driven gear 4, one side position of corresponding ratchet 5, on framework 2, be provided with ratchet 11 with matching, be articulated with two arms 12 in framework 2 front end both sides, two arms, 12 middle parts all are connected with cramp bar 13 separately, respectively are connected with a lifting rope 14, two lifting ropes 14 on the transmission shaft 3 two ends reels 7 and walk around the pulley 16 of the pulley 15 that is arranged on correspondence position on the framework 2 and two arms, 12 front ends and link to each other with the two ends of hanging basket 17.
The utility model adopts chassis and simple and easy lift system to form, and it is simple in structure, and volume is little, and cost is low, the walking conveniently moving, use very flexible, wide application, especially more convenient for the object handling in general goods yard.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, when the utility model used, the transmission device 19 that drives on the chassis 1 made wheel 20 walkings, can be flexible as common dolly.When running to goods stacking place, can car body be checked by the braking mechanism on the chassis 1 21.Can launch arm 12 this moment to the front upper place, and the cramp bar 13 at its middle part is connected framework 2 front ends, utilizes leg-of-mutton stability to make arm 12 fixing.But like this with regard to starter motor 9, it rotates the driven gear 4 on the transmission shaft 3 by driving gear 10, ratchet 5 on the transmission shaft 3 makes that under 11 effects of its ratchet transmission shaft 3 can only unidirectional rotation, such two lifting ropes 14 constantly are wrapped on the reel 7 at transmission shaft 3 two ends, thereby will hang basket 17 and winch to desired height, be convenient to the storing place that goods is put into eminence together with the goods in it.If need put, only need that chassis 1 is run to this place again and get final product to other place.
If when meeting power failure or other situation, rocking handle 18 can be sleeved on the transmission shaft 3, so just can realize the handling of goods by hand rocking handle 18.
After a handling process is finished, only need motor 9 is had a power failure, and ratchet 11 is opened, then the lifting rope 14 of transmission shaft 3 falls automatically hanging under basket 17 actions of gravity, and this moment, transmission shaft 3 and then lifting rope 14 counter-rotatings were ready for work next time.
If need when eminence is unloaded downwards, this moment, not only motor 9 had a power failure, and ratchet 11 is opened, but also will press drg 6, and the counter-rotating resistance on the transmission shaft 3 is increased, and prevented that goods is overweight and made and hang basket 17 and land quickly.
After work is finished, cramp bar 13 can be unclamped, two arms 12 are turned over to framework 2, also together the back dislocation is on arm 12 to hang basket 17, and folded finishing just received by handling mechanism like this, opens to get final product when following task again.
