Abstract
A moving hand crane is used for solving the transportation problem of heavy parts and tools during construction of power transmission lines. The moving hand crane is characterized in that a supporting base, a transmission mechanism and a steel wire rope roller are included, the transmission mechanism and the steel wire rope roller are arranged on the upper portion of the supporting base, the shaft end of a power input shaft of the transmission mechanism is provided with a crank insertion section, a crank is inserted into the crank insertion section, the steel wire rope roller is arranged on a power output shaft of the transmission mechanism, and a steel wire rope is wound on the steel wire rope roller. The moving hand crane is powered by man power, manual power is transmitted to the steel wire rope roller after being amplified by the transmission mechanism, and heavy articles are moved and conveyed to a tower. The moving hand carne greatly reduces labor intensity of operators, safety hidden risks of persons climbing up while bearing a load are eliminated, and the moving hand crane is simple in structure, compact in appearance, low in self-weight, capable of being moved and transported by two persons, convenient to use, and suitable for being used in small work sites of the power transmission lines and has a low requirement for use places.
Description
Technical field
The utility model relates to a kind of hand power tool, promotes and move the movable hand-crane of weight during in particular for transmission line construction.
Background technology
Replacing at transmission line construction is pitched in the operations such as beam, the correction of tower material, often heavy parts and instrument need to be transported to shaft tower.Adopt the method for a dead lift to require great effort very much, and workman bear a heavy burden to ascend a height safety misadventure more easily occur when aloft work; If adopt elevator machinery hoisting heavy, although can alleviate workman's onerous toil intensity, but common weight-lifting equipment has again the problem of self difficult, and often because be subject to the restriction of transmission line construction site condition, make weight-lifting equipment cannot enter workyard.For example, when transmission line of electricity is in farmland, entering of weight-lifting equipment can cause young crops damage, and then increases transmission line construction cost because reparation young crops loses.
Utility model content
The purpose of this utility model is the drawback for prior art, provide a kind of from heavy and light, be convenient to carrying, easy to operate movable hand-crane.
Problem described in the utility model is by realizing with following technical proposals:
A kind of movable hand-crane, special feature is: it comprises bearing, transmission device and steel wire rope roller, and described transmission device and steel wire rope roller are arranged on bearing top, wherein, the power input shaft axle head of transmission device is provided with crank plug-in mounting section, plug-in mounting crank in crank plug-in mounting section; Steel wire rope roller is arranged on the power take-off shaft of transmission device, lay winding wire ropes on steel wire rope roller.
Above-mentioned movable hand-crane, described transmission device is gear drive, transmission device is provided with power input shaft, tween drive shaft and power take-off shaft, power input shaft is provided with miniature gears, power take-off shaft is provided with big gear wheel, tween drive shaft is provided with dual gear, duplex big gear wheel and miniature gears engagement, duplex miniature gears and big gear wheel engagement.
Above-mentioned movable hand-crane, the two ends of described power input shaft are equipped with crank plug-in mounting section.
Above-mentioned movable hand-crane, described support both sides are provided with carrying handle.
The utility model heavy parts and instrument carrying problem and designed a kind of movable hand-crane when solving transmission line construction.Described movable hand-crane be take manpower as power, moves after transmission device amplifies man power and is delivered to steel wire rope roller, moves and carries weight to shaft tower.Adopt the utility model greatly to alleviate the labour intensity of operating personal, eliminated the potential safety hazard that artificial heavy burden is ascended a height; The utility model is simple in structure, compact appearance, from heavy and light, only need just removable carrying of two people, easy to use, to using field requirement low, the very suitable small-sized work-site of transmission line of electricity that is applied to, reaches the object that alleviates personnel labor intensity, improves construction operation safety.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
In figure, each list of reference numerals is: 1, bearing, 2, carrying handle, 3, crank plug-in mounting section, 4, steel wire rope roller, 5, crank, 6, power input shaft, 7, miniature gears, 8, duplex big gear wheel, 9, duplex miniature gears, 10, tween drive shaft, 11, big gear wheel, 12, power take-off shaft.
The specific embodiment
Referring to Fig. 1, the utility model comprises bearing 1, is provided with transmission device and steel wire rope roller on bearing.Stable for bearing is placed, in four supporting leg bottoms of bearing, be all provided with backing plate.Transmission device is provided with power input shaft, the axle head of power input shaft is provided with crank plug-in mounting section 3, for convenience of operation, power input shaft extends lengthening, at the two ends of power input shaft, be equipped with crank plug-in mounting section 3, plug-in mounting crank 5 easily in crank plug-in mounting section, by manually rotating crank to transmission device input torque.Steel wire rope roller 4 is arranged on the power take-off shaft of transmission device, lay winding wire ropes on steel wire rope roller.
Referring to Fig. 2, according to moment amplification principle, transmission device of the present utility model adopts secondary gear transmission.Parallel power input shaft 6, tween drive shaft 10 and the power take-off shaft 12 of being provided with of transmission device, power input shaft is provided with miniature gears 7, and power take-off shaft is provided with big gear wheel 11, and tween drive shaft is provided with dual gear, duplex big gear wheel 8 and miniature gears engagement, duplex miniature gears 9 and big gear wheel engagement.When artificial rotation crank, transmission device amplifies the moment of manually input through secondary, be delivered to power take-off shaft, by the steel wire rope roller of installing on power take-off shaft, weight is promoted or is moved.The transmitting ratio of transmission device can meet the demands by adjusting the number of teeth of each gear.
Referring to Fig. 1, Fig. 2, the utility model, for the ease of movement, is provided with carrying handle 2, two people's cooperations and just can be moved carrying in support both sides.
