Detailed description of the invention
Existing composition graphs 1 ﹑ figure 2 ﹑ Fig. 3 is further explained by the technical scheme of embodiment to the present embodiment of simple crane.
A kind of simple crane, comprise support 11, support 11 is provided with crossbeam 2 below top, crossbeam 2 is provided with hoisting device 1, and hoisting device 1 moves along crossbeam 2 direction.
Wherein, be completely fixed with fixed pan bottom support 11, fixed pan is advisable with ground.
Hoisting device 1 is preferably electric block, electric block is a kind of extraordinary weight-lifting equipment, retarder, lifting motor, operation motor, cutoff retainer, cable slide wire, roll device, cargo hook gear, coupler, flexible-cable electric current introducer etc. are integrated power and braking force by it, often be installed on overhead traveling crane, gauntry crane, it is little that electric block has volume, from heavy and light, simple to operate, the feature such as easy to use, for industrial and mining enterprises, the places such as storage harbour.The material of required transport carries out rising by electric block to be lifted to can the height of smooth mobile material, and the electric block material that plays moves along the length direction of crossbeam 2.
If but the curtailment of above-mentioned crossbeam 2 to cover work area time, then the present embodiment is fixed with girder 3 at support 11 top, crossbeam 2 by second walking assembly move along the length direction of girder 3 on girder 3.
Concrete working process is: after material lifted by hoisting device 1 liter, hoisting device 1 and material move along the length direction of crossbeam 2, because the present embodiment is provided with the second walking assembly between crossbeam 2 and girder 3, crossbeam 2 is moved by the length direction of the second walking assembly along girder 3.
By the technical program, crossbeam can move along girder length direction, and relatively traditional row hangs, and adds the driving surface of the hoisting device of the present embodiment.
Consider that the structure of the second above-mentioned walking assembly has multiple choices, what the present embodiment was exemplary provides the concrete structure of a kind of second walking assembly, and it includes transmission component and controller.
Wherein, transmission component is set at least two group pulley assemblies, pulley assembly includes pulley 6 and suspension rod 4, the pulley face of pulley 6 is conflicted at the lower surface of crossbeam 2, suspension rod 4 comprises the first suspension rod and the second suspension rod that center link 5 and two lay respectively at girder 3 both sides, one end and the girder 3 of the first suspension rod are fixed, the other end and center link 5 one end are fixed, center link 5 other end is fixed through pulley 6 and second suspension rod one end, pulley 6 does circumference rotation around the line of centers of center link 5, the second suspension rod other end and girder 3 are fixed, then crossbeam 2 is placed in the plane that adjacent pulleys 6 forms.
Moreover controller drives crossbeam to be moved by the length direction of transmission component along girder.
The effect that the technical program obtains is: because pulley block structure is simple, laborsaving, have energy-saving effect, more Jie Neng ﹑ is laborsaving to make the present embodiment.
Further, described controller includes electric machine controller 7, described electric machine controller 7 is vertically provided with gear wheel shaft 8, described gear wheel shaft 8 stretches out electric machine controller 7, described gear wheel shaft 8 external part is coaxially fixed with gear 10, described crossbeam is fixed with tooth bar 9 along the length direction of girder, and described tooth bar 9 engages with the gear 10 on gear wheel shaft 8.
Controller includes electric machine controller 7, electric machine controller 7 vertical direction is provided with gear wheel shaft 8, gear wheel shaft 8 stretches out electric machine controller 7, gear wheel shaft 8 stretches out electric machine controller 7, described gear wheel shaft 8 external part is coaxially fixed with gear 10, so, electric machine controller 7 is started working, control cincture movable gear shaft 8 rotates, so gear 10 is with the rotational speed identical with gear wheel shaft 8, crossbeam 2 is fixed with tooth bar 9 along the length direction of girder simultaneously, tooth bar 9 engages with the gear 10 on gear wheel shaft 8, form rack pinion, so the rotation of gear 10 can with the movement of carry-over bar 9, again because tooth bar 9 and crossbeam are fixed, so crossbeam can along the length direction displacement of girder together with tooth bar 9.
In sum, the present embodiment is by the rotation of electric machine controller 7 direct controlling and driving gear wheel shaft 8, reach the object of the rotation of pinion 10, again because gear 10 with and the tooth bar 9 fixed along the length direction of girder of crossbeam engage, move so the rotation of gear 10 can order about tooth bar 9 and crossbeam along the length direction of girder.And the use of controller improves the Zi Dongization ﹑ saving manpower of the present embodiment.
In addition, if row hangs transported material and not easily shakes, then, in the use procedure of hanging of being expert at, need to control the speed of crossbeam along the movement of girder length direction.Such as: when the material used is liquid or the object of other not easily fierce concussions.
So the present embodiment can be preferred: also preferentially can be provided with change speed gear box in electric machine controller 7, when transported material needs low speed to transport, electric machine controller 7 just changes the velocity of rotation of gear wheel shaft 8 by change speed gear box, finally make the speed range that the moving velocity of crossbeam 2 reaches suitable.
Concrete working process is: electric machine controller 7 passes through change speed gear box, reduce the velocity of rotation of gear wheel shaft 8, because gear wheel shaft 8 is fixed with gear 10, thus reduce the velocity of rotation of gear 10, because gear 10 and tooth bar 9 form rack pinion, then cause the reduction of tooth bar 9 speed.Again because tooth bar 9 and crossbeam 2 are fixed, so the moving velocity of crossbeam 2 can along with tooth bar 9 reduces under the effect of pulley assembly.If electric block is determined along the speed of crossbeam 2.In the scope that then reduction of crossbeam 2 moving velocity can make the travelling speed of substrate material reach suitable.
In addition this technical scheme is also applicable to the situation that material needs high-speed cruising.
So the advantage of the technical program is: the present embodiment by the velocity of rotation of change speed gear box pinion axle 8, thus can control the speed of crossbeam 2 along the movement of girder 3 length direction, to meet some to have requirement extraordinary circumstances to travelling speed.
Below be only the preferred implementation of the present embodiment, the protection domain of the present embodiment is also not only confined to above-described embodiment, and all technical schemes belonged under the present embodiment thinking all belong to the protection domain of the present embodiment.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the present embodiment principle prerequisite, these improvements and modifications also should be considered as the protection domain of the present embodiment.
