Abstract
The utility model relates to a hand-operated tractor-borne crane which relates to a crane and which is used for a tractor loading and unloading freight. The utility model mainly comprises a derrick mast (5), a boom (4), a pulley block (2), a winding drum (7), a hand wheel (10), etc. The utility model uses a pinion (8) to rotate the winding drum (7), and lifts heavy via the pulley block (2), solving the problem of difficult loading and unloading of the freight when the tractor is served as the transporting tool. The utility model has the advantages of simple structure, easy production, low cost, convenient use, etc.
Description
The manual truck-mounted crane of used with tractor relate to a kind of hoisting crane, are used for the trac. handling goods.
Existing trac. is pulled the compartment hoisting device is not installed, thus need to load and unload by other lifting facility, or be aided with manually goods to be packed into and pull in the compartment, the former increases expense, and latter's labour intensity is big, and work efficiency is low.
The purpose of this utility model provides a kind ofly pulls the manual truck-mounted crane of the used with tractor that manual truck-mounted crane are installed on the compartment at trac..
Feature of the present utility model is: steel rope (1) is wrapped on the reel (7) after connecting drop hanger (3) by assembly pulley (2); Be welded with a loop pillar pin (6) in the reel (7), pin (6) and miniature gears (8) engagement; Miniature gears (8) connects with handwheel (10) by axle (9).Arm (4) is movably hinged in (B), (C) point with gin pole (5); Gin pole (5) is fixedly connected on compartment (12) by framework (11).
Accompanying drawing the 1, the 2nd, master of the present utility model, left view.
Accompanying drawing 3 is that accompanying drawing 2(amplifies 6 times) cutaway view.
Existing accompanying drawings is as follows:
Steel rope (1) is wrapped on the reel (7) after connecting drop hanger (3) by assembly pulley (2), and arm (4) is movably hinged in (B), (C) point with gin pole (5), and gin pole (5) is fixedly connected on compartment (12) by framework (11).Be welded with a loop pillar pin (6) in the reel (7), pin (6) and miniature gears (8) engagement, miniature gears (8) connects with handwheel (10) by axle (9).
Now working process of the present utility model is described below:
Rotate handwheel (10) with manpower and drive miniature gears (8) rotation by axle (9), miniature gears (8) and pin (6) engagement drive reel (7) and rotate.Because the diameter of miniature gears (8) is 1/ (m) of reel (7) diameter, thus reel (7) go up power that steel rope (1) produces be applied to the manpower on the handwheel (10) m doubly.Steel rope (1) is assembly pulley (2) by the n multiplying power and drop hanger (3) contact again, then drop hanger (3) go up the power that produces for m * n of being applied to the manpower on the handwheel (10) doubly.Because arm (4) can be done 270 ° of rotations around gin pole (5), thus when making as long as suitably select the data of m and n, can be with the manpower weight of dilatory function carrying of slinging like a cork.
The utility model utilizes miniature gears (8) rotating drum (7), again by assembly pulley (2) hoisting heavy, the manpower that applies on the handwheel (10) is become can hoist the weight of trac. carrying, when having solved trac. as transportation means, the problem of handling goods difficulty.Alleviate labour intensity, improved efficiency, saved the energy.
The utility model also has the advantages such as simple in structure, easy to manufacture, with low cost, easy to use.
