Abstract

The utility model relates to a small hand-driven lifter, which is characterized in that a vertical shaft is fixed on a supporting bottom frame of a small lifter; a driven gearwheel is sheathed on the vertical shaft; a workbench is fixed on the upper surface of the driven gearwheel; after a cannula is sheathed on the vertical shaft, the vertical shaft is fixedly connected with the workbench; the top end of the cannula is hinged with a hoisting arm; a small hand-driven winch is arranged on the workbench; a wire rope is fixed on a winch roller; the other end of the wire rope is fixed on the back end of the hoisting arm; the front end of the cargo boom is fixed with a hoisting rope with a suspension hook; a hand-driven rotating device is fixed on the workbench; a power output shaft of the hand-driven rotating device is connected with a driving gear below the workbench; the driving gear is engaged with a driven gear. The utility model has the advantages that the utility model has simple mechanical structure, flexibility, convenience and complete manual operation without use of electricity, solving the problem that heavy objects are lifted on the occasions of low workshops, narrow space, workshops prohibiting electricity utilization, etc.

Description

A kind of manual telpher

One. technical field:

The utility model belongs to lifting machine, relates in particular to manual lifting machine.

Two. background technology:

Present short workshop and forbid that the workshop of current consumer all lifts weight with chain block at some ends, the chain block lifting needs to support with spider, and the marquis also is subjected to the restriction of workshop height sometimes, and it is very inconvenient to use.Therefore be sought after a kind of light manually operated lifting machine.

Three. summary of the invention:

The purpose of this utility model provides a kind of manual telpher, solves the lifting problem in above-mentioned workshop.

The technical solution of the utility model is: fix passive big gear wheel of cover on a vertical shaft, the vertical shaft on the support underframe of telpher, fix a bench board above the passive big gear wheel, a casing pipe sleeve is connected with stationary table after on the vertical shaft again, the hinged crane arm of cannula tip, arrange a manual puffer on the bench board, fixing steel cable on the winch drum, the steel rope other end is fixed on the crane arm rear end, and the crane arm front end is fixed the derrick line of a band suspension hook.Dolly winch makes crane arm upwards lift the weight of slinging.On bench board, also arrange a manual slewing arrangement, the power take-off shaft of manual slewing arrangement connects the driving gear below the bench board, driving gear and ring gear engagement, by manual operation, bench board and sleeve pipe rotate around vertical shaft together, thereby make the weight of slinging realize sway, finish lifting work.

In addition, lean forward when preventing to lift by crane very heavy object, support the underframe both sides hinged respectively on swing leg, strut when needing, combine with underframe when not required.

Good effect of the present utility model is: physical construction is simple, and is flexible, without electric power, uses manual operation fully, solved short workshop, small space, forbidden that the weight of the occasions such as workshop of electricity consumption lifts by crane problem.

Four. description of drawings:

Fig. 1 is the front view scheme drawing of embodiment, and Fig. 2 is the birds-eye view scheme drawing of embodiment.

Among the figure, 1-hinge, 2-crane arm, 3-derrick line, 4-suspension hook, 5-sleeve pipe, 6-column, 7-speed-change gear box, 8-driving gear, 9-swing leg, 10-adjustable diameter and screw adjusting bar, 11-land wheel, 12-support underframe, 12a-underframe crossbeam, 13-ring gear, 14-bench board, 15-puffer cylinder, 16-lift rope, 17-worm-and-wheel gear, 18-elevator manual pulley, 19-rotate manual pulley.

Five, the specific embodiment:

As shown in Figure 1 and Figure 2, at first support underframe 12 with one of shaped steel weldering, the structure of underframe 12 be splayed, trapezoidal, triangle all can, be splayed among Fig. 2.Welding one column 6 on the crossbeam 12a of underframe 12, column 6 bottoms put a ring gear 13, connect bench board 14 on 13, column 6 puts a sleeve pipe 5 again, ring gear 13, bench board 14, sleeve pipe 5 is fixed together, connect crane arm 2 on sleeve pipe 5 tops with hinge 1, the fixing derrick line 3 of going up band suspension hook 4 of crane arm 2 front ends, crane arm rear end fixation winding rope 16, lift rope 16 is fastened on the puffer cylinder 15 on bench board 14, the power of puffer 15 is provided by worm-and-wheel gear 17, by elevator manual pulley 18 rotary worms, puffer is rotated, on bench board 14, also be furnished with speed-change gear box 7, by rotation manual pulley 19, the gear of gear case 7 is rotated, and the power take-off shaft after the speed change is connected with driving gear 8, ring gear 13 engagements of driving gear 8 below bench board 14, thereby make sleeve pipe 5 and crane arm 2 realize rotating, make the weight sway of slinging.

Lean forward when preventing the lift heavy thing, be hinged with swing leg 9 at the underframe front end, the time spent struts, and the time spent does not amount on underframe 12, also is provided with adjustable diameter and screw adjusting bar 10 on the swing leg 9, is used for the ground leveling.

Claims
