The main engine is provided with a motor, a hoisting drum and a braking device, wherein the motor drives a driven gear on a drum shaft by a motor wheel driving a driving wheel on a driving shaft and a driving rack rail to reduce speed, and the hoisting drum is positioned on the drum shaft. The utility model has the advantages of simple structure, convenient operation, capability of temporary assembly, low manufacture and operation cost, convenient use and good effect.

Description

Make things convenient for hoisting crane

Technical field

The utility model belongs to a kind of hoisting crane that makes things convenient for.

Background technology

The crane applications scope is wider, is mainly used in short distance and starts shipment than the weight body.Common outdoor lifting is by crane-car, and the then available tackle block of indoor lifting, but traditional crane structure complexity are made the operating cost height, require great effort again during lifting charge.Especially not being suitable for interim lifting places such as rural area and transportation station uses.

Summary of the invention

Therefore, the purpose of this utility model is a kind of hoisting crane that makes things convenient for of design, and it is simple in structure that it is had, easy to operate, can assemble temporarily, makes low, the easy to use and effective advantage of operating cost.For this reason, bracing frame of the present utility model is positioned at an end and the middle part under the arm, the arm that is positioned at the bracing frame upper end of arm one end is provided with the counterweight sandbox, establish main frame walking rail on the arm, the road wheel at main frame two ends is positioned on the main frame walking rail, main frame is provided with motor, load drum, brake gear, and described motor is by the driven gear on power wheel on the motor wheel drive transmission shaft and the moving drum shaft of active rack rails deceleration strip, and load drum is positioned on the drum shaft.The said structure design has reached the purpose of this utility model.

Advantage of the present utility model has simple in structure, and is easy to operate, can assemble temporarily, and it is low, easy to use and effective to make operating cost.

Specific embodiments

As shown in Figure 1 to Figure 3, a kind of hoisting crane that makes things convenient for is made up of the load drum 3 on arm 5, main frame 4, the main frame, motor 23 and bearing seat 11.Bracing frame 8 is positioned at an end and the middle part under the arm, and the arm that is positioned at the bracing frame upper end of arm one end is provided with counterweight sandbox 1, and the effect of counterweight sandbox is to make the equal power of arm when main frame moves to the arm other end.Establish main frame walking rail 6 on the arm, the road wheel 2 at main frame two ends is positioned on the main frame walking rail, so that main frame moves back and forth on main frame walking rail, road wheel should be four and is positioned on the live axle 10 that is coupling with main frame (as shown in Figure 2, Fig. 2 only provides two road wheel structures, two road wheel structures are positioned at the main frame other end in addition, omit).Road wheel should have the race that is fastened on the main frame walking rail for this reason.Obviously arm should be frame-type, and two arms of band main frame walking rail should be on the framework both sides.The bracing frame of two arm lower ends should be four, but the arm bolt together of bracing frame upper end and corresponding position is integral during use, detachable tie bolt down of time spent not, and split is transported.Main frame is provided with motor, load drum, brake gear.Described motor makes the load drum that is positioned on the drum shaft rotate lifting by power wheel 16 driven gear 14 that 17 decelerations drive on the drum shaft 15 with the active rack rails that motor wheel 12 and belt conveyor 13 drive on the transmission shaft 18, one end of hoist rope 9 is fixed on the load drum, and the other end is a lifting hook.

For making after lifting puts in place or meeting emergency situation and put down weight, on main frame, to establish brake gear.Brake gear can be manual or electronic.Described brake gear is the hand-operated brake device, is made up of brake lever 7, the brake wheel 19, hand-operated brake sheet 20, retracing spring 25, brake cable 27, pulley 26 and the brake handle 28 that are positioned on the transmission shaft.The hand-operated brake sheet is positioned at the brake wheel outer end, one end of hand-operated brake sheet is coupling on the brake bearing 24 of brake wheel lower end, the other end connects an end of brake cable, the other end of brake cable is connected on the brake handle after leading by the pulley on the brake lever, retracing spring one end is positioned on the brake bearing, and the other end connects the hand-operated brake sheet.During brake, move brake handle with hand, the brake wheel that brake handle drive brake cable packs tightly on the transmission shaft hand-operated brake sheet is finished brake.Otherwise, unclamping brake handle under action of reset spring, the hand-operated brake sheet unclamps the brake wheel on the transmission shaft.

Described brake gear is an electrical brake device, is made up of brake wheel and the electromagnetic brake sheet 22 that is positioned at the brake wheel outer end.The electromagnetic brake sheet is sold product by market, and the brake wheel that the electromagnetic brake sheet can pack tightly on the transmission shaft after the energized is finished brake.Otherwise, unclamp.Obviously brake wheel also can be positioned at (shown in Fig. 2 dotted line position) on the motor shaft, and the identical event of its effect is not repeated.Also can adopt the counter-rotating of motor when having put down weight, the running of control motor and the operating case of electromagnetic brake sheet insert the main frame lower end by lead, for people's operation.Also establish reinforcement support beam 21 for increasing main frame intensity at the mainframe middle part.Transmission shaft, drum shaft, motor shaft and walking axle all are coupling on main frame by bearing seat.It is to rely on manually operated that main frame moves back and forth on main frame walking rail, as playing weight etc. with hand propelled or spurring with rope etc.

In a word, the utlity model has simple in structurely, easy to operate, can assemble temporarily, it is low, easy to use and effective to make operating cost.
