Detailed description of the invention
As shown in Figure 1 and Figure 2, the present invention is a kind of minor crane, by chassis 2, revolving dial 7, stand 5, arm 4 andLowering or hoisting gear 3 forms, and lowering or hoisting gear 3 has a structural framing 33, and the guide rail in structural framing 33 i.e. two parallel optical axises 38Coordinate and form moving sets with the corresponding hole 37 that connects firmly on revolving dial 7, can move up and down, on lowering or hoisting gear 3, be provided withBalancing weight 32 and pedal 31, its top is connected with rope sheave 310, and rope sheave 310 1 sides connect spiral spring 39, steel wire rope on rope sheave 31035 walk around arm 4 through pulley 36 is connected on hoisting heavy 9 by rigging 8.
Lockable mechanism on lowering or hoisting gear 3 is made up of alignment pin 313, location-plate 312, and alignment pin 313 connects with pedal 31Connect, location-plate 312 is arranged in structural framing 33.
The slow descending device on structural framing 33 tops by handle 314, eccentric wheel 315, press part 316, gangbar 317, stage clip318, brake block 319, brake wheel 311, gripper shoe 34 form, and handle 314 is fixedly connected on eccentric wheel 315, and stage clip 318 is enclosed withinIn gangbar 317, gangbar 317 front ends are hinged with eccentric wheel 315 through pressing part 316, and gangbar 317 tail ends are consolidated by boltDetermine brake block 319 one end, brake block 319 other ends are walked around brake wheel 311 and are bolted in gripper shoe 34.
Chassis 2 is planar metal frameworks, and Qi Sijiao is provided with road wheel 1, the pivoting support 10 that frame mid portion is installedConnect with revolving dial 7. Revolving dial 7 is also a planar metal framework, and bottom connects with pivoting support 10, top and liftingDevice connects, and connects with stand 5 by pull bar 6. Stand 5 is bolted and connects with revolving dial 7, arm 4 and stand 5Be bolted connection, connecting mode also can be welding or riveted joint.
Regulate balancing weight 32 quantity that move up and down according to the weight of hoisting heavy 9, manipulation of small crane handle 314,Eccentric wheel 315 makes gangbar 317 to being moved horizontally to range near brake wheel 311 1 sides, presses part 316 and gangbar317 afterbody spacing increase, and stage clip 318 is released energy, the brake block 319 releasing of brakes wheels 311 that gangbar 317 afterbodys connect, spiral spring 39Release and can drive rope sheave 310, brake wheel 311 together to rotate, rope sheave 310 is put rope, and another operator catches rigging 8 to be pulled down to suitable positionPut and be fixed on hoisting heavy 9, control crank 314 completes rope closing action clockwise, and now spiral spring 39 and stage clip 318 accumulation of energys, stopCar sheet 319 is held brake wheel 311 tightly, and rope sheave 310 is braked.
Step in high-order pedal 31, the lockable mechanism alignment pin 313 being connected is with it from being arranged in structural framing 33Location-plate 312 on locating hole deviate from, utilize the gravitational difference of manpower and balancing weight 32 and hoisting heavy 9, balancing weight 32 moves down, steelSilk rope 35 promotes hoisting heavy 9, and lowering or hoisting gear 3 unclamps pedal 31 go downwards to lower end extreme position under manpower effect time, fixedPosition pin 313 inserts in the lower locating hole of location-plate 312, and now lowering or hoisting gear 3 lockings, can handle crane hoisting heavy 9 is enteredRow horizontal shift.
The pedal 31 of gently stepping in low level is deviate from alignment pin 313 locating hole from location-plate 312, hoisting heavy 9Move down, when lowering or hoisting gear 3 is up to upper end extreme position under hoisting heavy 9 effect, unclamp pedal 31, alignment pin 313 withOn location-plate 312, locating hole coordinates, lowering or hoisting gear 3 lockings.
Control crank 314, makes eccentric wheel 315 control the slow releasing of brake wheel 311 of brake block 319, acts at hoisting heavy 9Lower rope sheave 310 is slowly put rope, after hoisting heavy 9 is in place, unclamps rigging 8, and spiral spring 39 is released can the rotational automatic rope closing that completes of rope sheave 310When action, joystick 314 makes brake block 319 hold brake wheel 311 tightly, and guarantee rigging 8 can not deviate from from pulley, and this is oneWorking cycles.
The present invention is applicable to construction temporary road or the on-the-spot precast concrete block of laying, and not affected by construction environment,Use manpower and material resources sparingly, the present invention also can be used for other and need to carry out the occasion of weight hoisting transportation.
