Abstract
The utility model discloses a rotary lifting trolley suitable for gantry cranes, which is characterized by comprising a trolley frame (4), upper and lower tracks (5 and 6) of a rotary mechanism, a lifting mechanism rack (2) and a lifting mechanism (1), wherein a trolley walking mechanism (3) is arranged at the bottom of the trolley frame (4); the upper and lower tracks (5 and 6) of the rotary mechanism are of ring-shaped structures and are arranged on the upper plane of the trolley frame (4); the lifting mechanism rack (2) is arranged above the upper track (5) of the rotary mechanism; the lifting mechanism (1) is arranged on the lifting mechanism rack (2); a rolling body (7) is arranged between the lower track (6) of the rotary mechanism and the upper track (5) of the rotary mechanism; and through a gear or pin gear (9) which is arranged at a power output shaft end, a rotary driving device (10) which is arranged on the lifting mechanism rack (2) is meshed with a gear ring or a pin gear ring (8) which is arranged around the periphery of the lower track (6) of the rotary mechanism.
Description
Technical field
The utility model relates to a kind of transfer crane, relates to lifting mechanism specifically and takes back a kind of isolated plant that change to drive---the swinging that the is applicable to transfer crane dolly that hoists.
Background technology
The lifting mechanism of existing transfer crane dolly is to be fixedly mounted on the trolley frame; Behind the mobile arrival assigned address through cart and dolly during work; Carry out the workpiece lifting; Workpiece can only up-and-down movement, could when assigned address is stacked or installed, can only rely on manual intervention to realize when the workpiece that is lifted by crane need change angle; For the large span transfer crane in lifting during big workpiece; Because workpiece is in the state that freely swings aloft bigger inertia is arranged; Rely on manual intervention to change relatively difficulty of angle orientation, and increased the danger of operating personal, the hidden danger certain the in place and security presence of workpiece; (, depositing after turning 90 degrees) when revolving after the access door lifting like the access door of ship lock in the traffic shipping engineering.Therefore, from improving closing Xing of the Zong Neng ﹑ work efficiency and the safe reliability of transfer crane, it is imperative to increase the transfer crane function, has important practical significance and essentiality.
Summary of the invention
The purpose of the utility model provides a kind of more perfect functions, the swinging that is applicable to transfer crane that safety the is good dolly that hoists just to existing weak point in the above-mentioned prior art.
The purpose of the utility model can realize through following technique measures:
The utility model is applicable to that the swinging of the transfer crane dolly that hoists comprises that the bottom is equipped with the trolley frame of carriage walking mechanism; Be installed in the upper and lower track of swing type mechanism of the loop configuration on the plane on the trolley frame; And be arranged on swing type mechanism get on the right track the top the lifting mechanism frame, be installed in the lifting mechanism on the lifting mechanism frame; , swing type mechanism lower railway and swing type mechanism be provided with rolling body between getting on the right track; The device for revolving and driving that is installed on the lifting mechanism frame is meshed with gear ring that is provided with around swing type mechanism lower railway periphery or pin gear ring through gear or the pin gear that is installed in the takeoff output axle head.
The principle of work of the utility model is following: device for revolving and driving (electric power or hydraulic-driven) is through the engagement transferring power and the motion of gear (or pin gear) and gear ring (or pin gear ring); The lifting mechanism frame is rotated in fixed axis, thereby realize that lifting mechanism drives the revolution of workpiece.
The beneficial effect of the utility model is following:
1, adopts rotary structure to hoist dolly in use, increased the function of transfer crane, the Combination property of transfer crane work efficiency, applicability, reliability and safety is improved.
2, adopt the rotary structure dolly that hoists, make the operation of transfer crane more flexible, can all standing in scope of work, workpiece can any 360 degree rotations, and alerting ability is strong, degree of utilization is high, does not stay the dead angle.
3, lifting mechanism can be realized self-orientation through rolling body between the upper and lower track of swing type mechanism; Guaranteed that swing type mechanism rotates in fixed axis, because simple in structure, made, cost of installation is low; Thereby be convenient in daily use, safeguard, can reduce effectively production maintenance cost and time.

Fig. 2 is the birds-eye view (view behind the removal machine room) of Fig. 1.
Fig. 3 is the structural representation of the upper and lower track of swing type mechanism in the utility model.
Sequence number among the figure: the 1st, it is that lifting mechanism Ji Jia ﹑ 3 is that carriage walking Ji Gou ﹑ 4 is that dolly Jia ﹑ 5 is that swing type mechanism Shang Gui Dao ﹑ 6 is that Gui Dao ﹑ 7 is that Gun Dong Ti ﹑ 8 is gear ring or pin gear ring, the 9th Xia the swing type mechanism that Qi rises Ji Gou ﹑ 2, gear or pin Chi Lun ﹑ 10 are device for revolving and driving (propulsion source are electrical motor or HM Hydraulic Motor).
The specific embodiment
Like Fig. 1, shown in Figure 2; The swinging that is applicable to transfer crane of the utility model dolly that hoists comprises that the bottom is equipped with the trolley frame 4 of carriage walking mechanism 3; Be installed in the upper and lower track 5,6 of swing type mechanism of the loop configuration on the plane on the trolley frame 4; And be arranged on the get on the right track lifting mechanism frame 2 of 5 tops of swing type mechanism, be installed in the lifting mechanism 1 on the lifting mechanism frame; , swing type mechanism lower railway and swing type mechanism be provided with rolling body 7 between getting on the right track; Be installed in device for revolving and driving 10 on the lifting mechanism frame 2 gear or the pin gear 9 through being installed in the takeoff output axle head and be provided with gear ring or pin gear ring 8 be meshed (referring to Fig. 3) around swing type mechanism lower railway 6 peripheries.
