Abstract

The utility model relates to a manual loader which uses human power to drive a steel cable hoister via a lever, a pawl and a ratchet. The utility model comprises a suit of speed limiting braking device which is composed of a brake strap for connecting a steel cable, a brake strap wheel installed on the steel cable hoister, a tension spring, a balance wheel and a tooth cog wheel, being able to effectively prevent tub squatting. When steel tubs are loaded, an embracing chain cable can be used. The utility model is practical and convenient.

Description

Manual loader

The utility model relates to the instrument of objects such as carrying, loading and unloading steel drum, and is particularly a kind of by the manually driven loader.

Loader can be divided into dynamo-electric driving and manpower drives two classes.The available man-power loader comprises forms such as hand-hydraulic, worm and gear transmission, differ from one another, but general cost is higher, efficient is on the low side.

The purpose of this utility model is development manual loading's machine that a kind of cost is lower, mechanical efficiency is high, easy and simple to handle.

Task of the present utility model is finished like this: at the crane that one pair of band fixed pulley of vertical position welding on the vehicle frame of road wheel is arranged.The lever of being removed by foot-operated or hand is housed on the vehicle frame, walks around fixed pulley lifting balladeur train by winch, the winch steel rope of ratchet, ratchet drives cable drum.Have on the balladeur train and block chain rope and the pallet fork of embracing objects such as steel drum.The limiting brake mechanism that establishes in order to prevent " bucket of squatting " is by the strap of the brake, strap of the brake wheel, tension spring, control handle and tooth embedding wheel, compositions such as escapement.When goods is hung on the crane, produces friction force with the steel rope one end bonded assembly strap of the brake and strap of the brake wheel and make the unlikely downslide of goods.During unloading, the friction force between operating control handle, change tension spring are taken turns with the minimizing strap of the brake and the strap of the brake the application force of steel rope, by tooth embedding wheel and escapement speed limit, goods is safe falling inchmeal.

Owing to adopted the said structure design, the utility model operation is light, is particularly useful for carrying steel drum.During operation lifting freely, safe and reliable, can stop " squat bucket " accident.

Below with reference to accompanying drawing utility model is further described.

Fig. 1 is the profile scheme drawing of a kind of embodiment of the utility model.

Fig. 2 is the fundamental diagram of a kind of embodiment of the utility model.

With reference to Fig. 1, Fig. 2.The vehicle frame 10 of manual loading's machine is equipped with four road wheels 12, and wherein two are the optional turning wheel.Crane 3 vertically is welded on the vehicle frame 10.Balladeur train 9 can slide up and down in crane 3.Balladeur train 9 is by steel rope 2 tractions, and fixed pulley 1 is installed in crane 3 tops, and movable pulley 8 is installed on the balladeur train 9.The cable drum 15 of winch is driven by ratchet 17, ratchet 18 by pedal 20, lever 19.Establishing two kinds of carrying apparatus according to description of cargo sets level the pallet fork 7 of balladeur train 9 bottoms and can shovel, hold in the palm goods; During cylinder such as carrying steel drum etc., upwards pack up pallet fork 7, with the chain rope 5 on the balladeur train 9 tops steel drum 4 of seizing round the middle, because balladeur train 9 is positive curved, steel drum 4 is close to balladeur train 9, and is stable fine in the lifting.In order to prevent " bucket of squatting " effectively, break goods that at the strap of the brake wheel 23 of lifting drum 15 1 end mounting strap tooth embeddings wheel 22, winch steel rope 2 one ends are connected with the strap of the brake 19.Establish the control handle 6 of an adjustment tension spring 13 on crane 3, tension spring 13 is grappled lifting wire rope 2.21 engagements of tooth embedding wheel 22 and one escapement.Constitute a cover limiting brake device like this.

During lade, down pedal 20, and lever 11 drives ratchet 17, drive cable drum 15 lifting cargos by ratchet 18.Pull back spring 16 can make pedal 20 reset.Fall goods as need, earlier pedal 20, lever 11 are raised to the position of limiting stopper 14, ratchet 17 and ratchet 18 are thrown off, reel 15 could reverse, but produce friction force because cargo weight tense wire rope 2 makes the strap of the brake 12 press strap of the brake wheel 23, reel 15 can't reverse.Also need move control handle 6, handle tension spring 13, reduce the friction force between the strap of the brake 19 and the strap of the brake wheel 23, reel could reverse.By the control of escapement 21 and tooth embedding wheel 22, can be not out of control when reel 15 reverses, goods just can steadily be fallen safely.

Claims

1, a kind of manual loading's machine of being made up of wheeled vehicle frame, lifting mechanism and winch is characterized in that:

Reel one end of a, said winch is equipped with the strap of the brake wheel of band tooth embedding wheel, and winch steel rope one end is connected with the strap of the brake on the strap of the brake wheel, and a tooth embedding wheel and a speed limit escapement mesh;

Be equipped with the tension spring of grappling lifting wire rope and the control handle of controlling the tension spring pulling force on the crane of b, said lifting mechanism;

The balladeur train front of c, said lifting mechanism is circular arc, and balladeur train top has blocks the chain rope of embracing objects such as steel drum, the pallet fork that the bottom in addition can folding and unfolding.

2, manual loading's machine according to claim 1 is characterized in that the actuating device of said winch is made up of band manpower pedal, pull back spring and the lever of ratchet and the ratchet of winch cable drum one end.
