Column (the being specially vertical columns 6) bottom of the present embodiment is hinged by bearing pin 15 and underframe 7 (i.e. basic crossbeam 9), namely column can be that the center of circle overturns with hinge-point, therefore, the present embodiment is provided with the vertical column locking device 35 that the column being in horizontality is locked on underframe 7 by the sliding hammer latching device 16 and being used for for being pinned by the column being in vertical state on underframe 7.
With reference to figure 4 and Fig. 5, the sliding hammer latching device 16 of the present embodiment comprises the first stay bearing plate 26, second stay bearing plate 37, sliding hammer mechanism and the locking taper pin 20 cooperatively interacted and lock 21, first stay bearing plate 26 and the second stay bearing plate 37 are outside in fixedly installed on basic crossbeam 9 successively, and sliding hammer mechanism comprises pipe link 23, be sleeved on the sliding hammer block 25 that pipe link 23 also can slide on pipe link 23, the two ends of pipe link 23 are supported by the first stay bearing plate 26 and the second stay bearing plate 37 respectively, pipe link 23 is outside in fixedly installed successively the first hammering plate 24 and the second hammering plate 22, first hammering plate 24 and the second hammering plate 22 lay respectively at sliding hammer block 25 both sides, locking taper pin 20 is fixedly installed on pipe link 23 one end towards vertical columns 6, locking taper pin 20 is tapered towards the end of vertical columns 6, lock 21 is fixedly connected with vertical columns 6, because the present embodiment is also provided with diagonal brace 14, therefore, lock 21 is fixedly welded on diagonal brace 14, and lock 21 is provided with and the taper hole of locking taper pin 20 end and matching.
In addition, basic crossbeam 9 is provided with the 3rd stay bearing plate 36,3rd stay bearing plate 36 is between the first stay bearing plate 26 and the second stay bearing plate 37,3rd stay bearing plate 36 top is hinged with the baffle plate 13 that can carry out overturning, and the length of baffle plate 13 need to be inserted into the stroke that lock 21 needs consistent with locking taper pin 20.
Sliding hammer latching device 16 can prevent its column being in vertical state from moving and toppling, its use principle is: when column is in vertical state, sliding hammer latching device 16 on operation underframe 7, the second hammering plate 22 is knocked by sliding hammer 25, pipe link 23 can move to the direction of column, locking taper pin 20 to be pounded the taper hole to lock 21, after in the wedging to lock 21 taper hole of locking taper pin 20, turned down by baffle plate 13, baffle plate 13 blocks the second hammering plate 22 and prevents locking taper pin 20 rollback.
With reference to figure 6, the vertical column locking device of the present embodiment comprises jam plate 28, support 29, handle 31 and position-limited lever 32, the connecting panel 29.2 that support 29 comprises two stay bearing plates be arranged in parallel 29.1 and is fixedly connected with two stay bearing plate 29.1 tops, stay bearing plate 29.1 is fixedly installed on basic crossbeam 9, and position-limited lever 32 is arranged on handle 31 end, position-limited lever 32 is through stay bearing plate 29.1, position-limited lever 32 is arranged with spring 30, spring 30 one end is connected with the stay bearing plate 29.1 being positioned at outside, spring 30 other end is fixedly connected with the positioning plate 38 be fixedly set on position-limited lever 32, positioning plate 38 is between two stay bearing plates 29.1, the front end of position-limited lever 32 is inclined-plane upward, jam plate 28 is fixedly connected on vertical columns 6, jam plate 28 is provided with the spacing hole that width is greater than position-limited lever 32 external diameter.When column fell rear support on underframe 7 time, the position-limited lever 32 of handle 31 front end to insert in the spacing hole of jam plate 28 to be locked by column, prevents column from offseting.
The present embodiment is provided with elastic buffering mechanism 12 on basic crossbeam 9, and elastic buffering mechanism 12 is selected as polyurethane energy disperser, is used for buffering upright to fall down to the impact of underframe.
The present embodiment is also connected by extension spring 19 with vertical columns 6 at basic crossbeam 9, extension spring 19 is connected with the first permanent seat 17 be fixedly installed on basic crossbeam 9 and the second permanent seat 18 be fixedly installed on vertical columns 6 respectively, with the application force be used for during buffering upright upset.Extension spring 19 also has an effect herein: column by level to plumbness erect time, extension spring 19 shrinks the power that column has individual pull-up, is used for alleviating the artificial application force dug by column, reaches labour-saving and acts on.
The operating process of the portal crane of the present embodiment is:
One, assemble: first telescopic column 4 is pulled out in vertical columns 6, insert by movable latch 27 and telescopic column 4 is fixedly connected with vertical columns 6, then, intermediate transverse girder 1 bolt, nut 2 are connected together with left and right column, and chain block is hung on manual electrified monorail system 11;
Two, column upwards overturns: each station one people outside left and right stud edge, pulls out the position-limited lever 32 of left and right vertical column locking device in jam plate 28 hole; Then, two operators respectively upwards enforce column; Now, left and right column upwards digs upright state under the combined action of the convergent force of extension spring 19 and the thrust of people;
Three, lock column: when vertical state translated into by left and right column, the sliding hammer latching device 16 on operation underframe 7, to be locked by column, prevents it from moving and overturns.
Now, the lifting work of portal crane can be started.When indoor use, crane does not need to pack up, and just uses in upright state always.When needs use in the wild, need crane to fall, folding, pack up, control step is as follows:
One, locking removed by column: dug by baffle plate 13, and operation sliding hammer latching device 16, exits locking taper pin 20, exit rear baffle plate 13 and block the second hammering plate 22 in lock 21 taper hole;
Two, column pushes over: each station one people outside left and right stud edge, column is pushed over forward, now, left and right column is under the thrust combined action of extension spring 19 tensile force and people, the tensile force balance thrust of people of spring and the gravity of column, column slowly falls down, and column fell rear support on underframe 7, then inserts in jam plate 28 spacing hole with the position-limited lever that column to be locked at i.e. handle 31 front end on underframe 7 by vertical column locking device 35 and locked by column.
Three, be separated with left and right column by intermediate transverse girder 1, place separately, now, crane is broken down into left and right underframe and intermediate transverse girder 1 three part, can load and transport respectively, assemble to work-site again.
The present invention is easy to assembly, fast, improves work efficiency, and the operation of crane can by spring force, and rapid operation easily, alleviates labor strength, is that one was both applicable to field work, is also adapted at the portal crane used in stationary applica-tions.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to structure of the present invention.Every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical scheme of the present invention.
