The specific embodiment
As Fig. 1, shown in Fig. 2, the present invention is a kind of minor crane, by chassis 2, turn table 7, stand 5, arm 4 and jacking system 3 form, jacking system 3 has a structural framing 33, guide rail in structural framing 33 i.e. two parallel optical axises 38 coordinates formation moving sets with the corresponding hole 37 that connects firmly on turn table 7, can move up and down, on jacking system 3, be provided with clump weight 32 and stretcher 31, its top is connected with rope sheave 310, rope sheave 310 1 sides connect spiral spring 39, on rope sheave 310, steel rope 35 is walked around arm 4 through pulley 36 and is connected on hoisting heavy 9 by rigging 8.
Lockable mechanism on jacking system 3 is comprised of locating dowel pin 313, locating plate 312, and locating dowel pin 313 is connected with stretcher 31, and locating 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 clip 318, brake facing 319, brake wheel 311, stay bearing plate 34 and form, handle 314 is fixedly connected on eccentric wheel 315, stage clip 318 is enclosed within gangbar 317, gangbar 317 front ends are hinged with eccentric wheel 315 through pressing part 316, gangbar 317 tail ends are bolted brake facing 319 one end, and brake facing 319 other ends are walked around brake wheel 311 and are bolted on stay bearing plate 34.
Chassis 2 is planar metal frameworks, and Qi Sijiao is provided with road wheel 1, and the pivoting support 10 that frame mid portion is installed connects with turn table 7.Turn table 7 is also a planar metal framework, and bottom connects with pivoting support 10, and top connects with jacking system, and connects with stand 5 by pull bar 6.Stand 5 is bolted and connects with turn table 7, and arm 4 is bolted and connects with stand 5, and connecting mode also can be welding or riveted joint.
According to the weight of hoisting heavy 9, regulate clump weight 32 quantity that move up and down, manipulation of small crane handle 314, eccentric wheel 315 makes gangbar 317 to being moved horizontally to range near brake wheel 311 1 sides, pressing part 316 increases with gangbar 317 afterbody spacing, stage clip 318 is released can, the brake facing 319 releasing of brake wheels 311 that gangbar 317 afterbodys connect, spiral spring 39 is released and can be driven rope sheave 310, brake wheel 37 together rotates, rope sheave 310 is put rope, another operator catches rigging 8 to be pulled down to correct position and is fixed on hoisting heavy 9, cw bar handle 314 completes rope closing action, now spiral spring 39 and stage clip 318 accumulation of energys, brake facing 319 is held brake wheel 311 tightly, rope sheave 310 is braked.
Step in high-order stretcher 31, the lockable mechanism locating dowel pin 313 being connected with it knock hole on being arranged in the locating plate 312 of structural framing 33 is deviate from, utilize the gravitational difference of manpower and clump weight 32 and hoisting heavy 9, clump weight 32 moves down, steel rope 35 promotes hoisting heavy 9, jacking system 3 unclamps stretcher 31 while going downwards to lower end end position under manpower effect, locating dowel pin 313 inserts in the lower knock hole of locating plate 312, now jacking system 3 lockings, can handle hoisting crane hoisting heavy 9 is carried out to horizontal displacement.
The stretcher 31 of gently stepping in low level is deviate from locating dowel pin 313 knock hole from locating plate 312, hoisting heavy 9 moves down, when jacking system 3 is up to upper end end position under hoisting heavy 9 effects, unclamp stretcher 31, locating dowel pin 313 coordinates with knock hole on locating plate 312, jacking system 3 lockings.
Bar handle 314, make eccentric wheel 315 control the slow releasing of brake wheel 311 of brake facing 319, under hoisting heavy 9 effects, rope sheave 310 is slowly put rope, after hoisting heavy 9 is in place, unclamp rigging 8, spiral spring 39 is released control handle 314 when energy rope sheave 310 is rotational automatic completes rope closing action makes brake facing 319 hold brake wheel 311 tightly, assurance rigging 8 can not deviate from from pulley, and this is a working cycle.
The present invention is applicable to building operation shoofly or the on-the-spot precast concrete block of laying, and not affected by construction environment, uses manpower and material resources sparingly, and the present invention also can be used for other occasions that need to carry out weight hoisting transportation.
