Abstract
The utility model discloses a manual-driving crane. The worm wheel output shaft of the hoisting mechanism is used as the drum of the manual-driving crane; the middle part of the manual-driving crane is provided with a steel rope pressing roller, the top end of the manual-driving crane is hinged with the upper frame of the hoisting mechanism, the bottom end of the manual-driving crane is provided with two sets of bracket rods which are tensed by return springs; the shaft end gear wheel of the pressing roller is engaged with a gear ring, and the gear ring is arranged at the worm wheel output shaft. When the utility model is used, the curling and overlapping phenomenon of the steel rope is not generated, the drain and the retraction can proceed accurately, and the excess grind of the steel rope and the pressing roller can be avoided at the same time. The lifting height of the manual-driving crane can reach to 2.3 meters, the lifting load capacity is 300-500 kg, and the weight of the manual-driving crane can not exceed to 100 kg.
Description
The utility model provides a kind of manpower operation crane, is made of end car, vertical rod, hack lever and elevator assembly, belongs to the conveying machinery technology.
At present, how lifting weight below 500 kilograms is undertaken by fork truck.But when fork truck carried out lifting operation in narrow and small warehouse, operational space or business office, the lifting weight can not accurately lean on the deficiency performance of position very obvious.Kind of the manpower transport's dolly that is equipped with small-sized hand-operated elevator is arranged, can satisfy the demand of lifting weight below 300 kilograms, and possess characteristics flexible and convenient to use.But because of can't in use solving lifting steel cable clot on reel, overlapping, and problems such as elevator, volume are big, heaviness, and obtain generally to use.
At the above-mentioned deficiency of lifting small dimension weight machinery, the purpose of this utility model provides a kind of suitable lifting weight below 500 kilograms, can be in the small space normal operation, and can guarantee the lifting weight accurately by manpower move crane.
The purpose of this utility model, realize by taking following technical measures:
Car at the bottom of by manpower is located at end car upper pright stanchion, is equipped with in the manpower operation crane that the rod end hack lever of elevator assembly formed, and be reel with the worm gear output shaft of hoisting mechanism.The middle part also is set is equipped with the steel cable hold-down roll, the top is hinged on the two pack support bars that hoisting mechanism upper frame, bottom are strained by pull back spring, and its hold-down roll shaft end gear meshes with the gear ring of worm gear output shaft configuration.
Manpower operation crane provided by the utility model is owing to directly make whim, the hoisting mechanism overall dimensions is obviously reduced with the worm gear output shaft.Hold-down roll under the effect of pole bottom tension (return) spring, effectively with the steel cable rolling touch, guarantees that steel cable does not produce clot, overlapping phenomenon with the counter-rotating of worm gear output shaft.When discharging exactly or regaining, the too much wearing and tearing of steel cable and hold-down roll have also been avoided.The employing of Worm wheel transmission mechanism, laborsaving significantly, the ability of lifting weight is significantly improved.Manpower operation crane sling height can reach 2.3 meters, and hanging carrying capacity is the 300-500 kilogram, and manpower operation crane weight is no more than 100 kilograms.
Accompanying drawing is the organigram of manpower operation crane.Wherein Fig. 1 is the structural representation of manpower operation crane, Fig. 2 is the lateral plan of manpower operation crane, Fig. 3 is worm and gear and an output shaft parts structural representation in the hoisting mechanism, and Fig. 4 interconnects position view for pole and hold-down roll and worm gear output shaft, and Fig. 5 is the reel assemblies birds-eye view.Below in conjunction with accompanying drawing,, further narrate technical characterictic of the present utility model by most preferred embodiment.
Manpower operation crane, by end car (1), be located at end car upper pright stanchion (2), the top hack lever (4) that is equipped with elevator assembly (3) formed.Worm gear output shaft (5) with hoisting mechanism is a reel, and worm gear output shaft (5) is a stepped shaft.The middle part is equipped with hold-down roll, and the bottom is by two pack support bars (11) of pull back spring (8) tension, and the top is hinged on the hoisting mechanism upper frame, gear ring (9) engagement of its hold-down roll shaft end gear (10) and worm gear output shaft (5) configuration.
In the present embodiment, be installed with axle sleeve (6) on the output shaft (5), gear ring (9) is configured on the axle sleeve.When considering reel revolution (rope), steel cable and reel be adjacent to trend automatically, no longer include clot, overlapping possibility, in order to reduce the wearing and tearing of gear ring (9) and hold-down roll shaft end gear (10), ratchet (12) is set on the gear ring (9), restriction the turning to of hold-down roll, only make its in putting the rope process and output shaft (5) with commentaries on classics.
Claims (3)
1, a kind of manpower operation crane is made of end car, vertical rod, hack lever and elevator assembly, and the worm gear output shaft that it is characterized by with hoisting mechanism is a reel; The middle part is set is equipped with the steel cable hold-down roll, the top is hinged on the two pack support bars that hoisting mechanism upper frame, bottom are strained by pull back spring, and its hold-down roll shaft end gear meshes with the gear ring of worm gear output shaft configuration.
2, manpower operation crane according to claim 1, it is characterized by worm gear output shaft (5) is stepped shaft, is installed with axle sleeve (6) on the output shaft (5), gear ring (9) is configured on the axle sleeve.
