Punched iron sheets and angle irons are adopted to be firmly fixed and joined by overlapping by a bolt. A motor is used as a dynamic force, a winding engine is composed by means of the driving modes of a worm wheel and a worm, with a lifting rope pulled, and the rising and falling actions of a hook and the raising and pronating actions of a crane arm are realized in order to lift a clog, a motor-driven rotary mechanism can make the lifting arm make the rotation of 360 DEG. The utility model can well simulate the working process of the tower crane, and the conformation of the utility model is also similar to the tower crane.

Description

Toy tower crane

The utility model is a kind of contour structures and operation principle of simulating tower crane, the electric model toy of energy practical operation.

Popular Toy tower crane only is a kind of static models that dwindle in ratio in kind at present, can supply to view and admire, but can not practical operation.Can not demonstrate the operation and the operation principle of tower crane.Other has a kind of plastic toy tower crane, though also installed dynamical system, its structure adopt plastic monoblock or divide several big injection molded.Different with the structure that actual tower crane adopts the hardware overlap joint to form, be not a kind of genuine tower crane model toy that resembles.

The purpose of this utility model provides a kind of simulation model of tower crane.Structure is similar with tower crane, and operation principle is basic identical, can simulate the operating process of tower crane, demonstrates the electric model toy of its operation principle.

The purpose of this utility model is achieved in that

The support of Toy tower crane, body of the tower and crane arm, counter-jib all adopt the iron plate and the angle bar of punching press, form with the bolted overlap joint.This structure is similar with the practical structures of tower crane.Crane arm links to each other with lifting rope with hoisting mechanism with suspension hook.Under the manipulation of hoisting mechanism, can realize facing upward, bow and the ascending, descending campaign of suspension hook of crane arm.Hoisting mechanism is power with the motor, and the kind of drive adopts worm gear, worm-drive, can realize self-locking.Connect by rotating mechanism between counter-jib and crane arm and the support.Under the motor-driven of rotating mechanism, crane arm can be done 360 ° of rotations along horizontal plane.Whole device is handled by control box control.The battery power source.Each free degree co-operating just can arbitrarily be lifted by crane, moving heavy object, simulation tower crane operative scenario.

Owing to adopt such scheme, the utility model all similar in appearance to tower crane, operating process that can the realistic simulation tower crane, is demonstrated its operation principle on contour structures and the operation principle.Assemble voluntarily by children after can also splitting into loose mail, children are at play temper manipulative ability in the process, strengthen intuitivism apprehension power, cultivate operative skill, develop the mind.

Below in conjunction with drawings and Examples the utility model is further specified.

Among Fig. 1 embodiment, support (1) is as the mechanics supporting of whole device.Guarantee whole device stable equilibrium, unlikely overturning.Two kinds of fixed forms are arranged at its bottom (10), and a kind of is to be directly fixed on desktop etc. to locate, and second kind is 4 wheels of installing, can move.Rotating mechanism (3) is fixed on the support (1).Body of the tower (2), counter-jib (5) and on hoisting mechanism (4), connecting piece (22) that crane arm (6) all is installed in rotating mechanism (3) on.Suspension hook (7) links by lifting rope (8) and hoisting mechanism (4).All action is handled by control box (9).Fig. 6 is the control circuit electrical schematic diagram.

The concrete structure and the operation principle of each several part are such.

Angle bar (11) that support (1), counter-jib (5), body of the tower (2) and crane arm (6) are stamped to form by sheet iron and iron plate (12), (13) form with the bolted overlap joint.As shown in Figure 2.The user can do it yourself to dismantle and assembling.

Hoisting mechanism (4) is to be rotated by the worm screw that motor (15) drives on it, thereby drives worm gear (16), passes through after a pair of gear (17) slows down spool (18) is rotated again, and is wrapped in lifting rope (8) on the spool (18) and is reeled or emit.The pulley that lifting rope (8) strides across body of the tower top and crane arm top connects suspension hook (7).Lifting rope (8) is reeled or when emitting, suspension hook (7) just rises or descends.The structure of hoisting mechanism (4) as shown in Figure 3.Another set of identical hoisting mechanism is realized the action of facing upward, bow of crane arm.Adopt worm gear, worm-drive mode in the hoisting mechanism (4), had very big speed reducing ratio, and had self-locking action.Promptly can only drive worm gear with worm screw, and can not use the worm gear drives worm screw, need only the motor stall like this, weight just rests on any lifting position, and can not fall because of deadweight.

Rotating mechanism (3) also adopts worm gear, worm-drive mode, as shown in Figure 4.The worm screw that motor (19) drives on the axle is rotated, and drives worm gear, rotates by deceleration tooth (21) deceleration rear drive connecting piece (22).Body of the tower (1) and crane arm (6), counter-jib (5) are fixed on the connecting piece (22), the rotation of realization crane arm (6) under connecting piece (22) drives.

Suspension hook (7) adopts the same lifting rope of movable pulley mode (8) to connect, to increase hoisting weight and stability.The structure of suspension hook (7) as shown in Figure 5.

Control box (9) comprises battery (31), (32) and switch (26), (27), (28), (29), (30).Electrical schematic diagram such as Fig. 6 adopt two joint 1.5 volts of batteries (31), (32) power supply.Two batteries are in parallel generally speaking uses, and 1.5 volts of voltages are powered to motor.Can be converted to two batteries (31), (32) series-fed, 3 volts of voltages by change-over switch (30).About motor speed is doubled, reach the purpose of speed change.

Toy tower crane bottom (10) can be rigidly secured on desktop or other pedestal, increases stability.Also can install four wheels, whole device can be moved, be flexible within certain limits.

The method of operating of this utility model Toy tower crane: with the battery cathode and anode directions in accordance with regulations control box of packing into.Press press button (28), motor (15) rotates, and suspension hook rises.Press press button (26), the motor of another set of hoisting mechanism (25) rotates, and crane arm is faced upward, and presses press button (27), and the motor (19) of rotating mechanism (3) rotates, and crane arm rotates along clockwise direction.After stirring change-over switch (29), press above-mentioned the corresponding button, the action of tower crane each several part is opposite.After stirring change-over switch (30), motor is converted to 3 volts of power supply power supplies by 1.5 volts of power supply power supplies, and rotating speed increases, and realizes speed change.Hang up the weight operation on the suspension hook, can demonstrate the practical work process of tower crane.
