Abstract
The utility model relates to a kind of oblique pull safety of gantry crane formula walking system.The purpose of this utility model is to provide a kind of oblique pull safety of gantry crane formula walking system, gantry crane trolley can be driven normally to walk, monkey is made to bear in the optional position of walking the lateral pull having certain angle with track, and in the horizontal direction automatic safe locking is carried out to monkey, ensure that monkey can carry out oblique pull operation at an arbitrary position.The technical solution of the utility model is: a kind of oblique pull safety of gantry crane formula walking system, monkey is arranged on two tracks on oblique pull gate type portal gantry top by wheel assembly, two self locking type screw rod machines are connected by hinged connecting device bottom monkey one end, be connected with synchronizing shaft device between two self locking type screw rod machines, self locking type screw rod machine is fixed through the door frame of support and oblique pull transfer crane.The utility model is applicable to water power hydraulic engineering and similar field.
Description
Technical field
The utility model relates to a kind of oblique pull safety of gantry crane formula walking system.Be applicable to water power hydraulic engineering and similar field.
Background technology
Transfer crane normal design operating mode is vertical-lift work, and the driving mechanism design type of dolly is that ground-engaging wheel relies on wheel and interorbital friction force to run to drive the walking of dolly.But in water power hydraulic engineering, sometimes for reducing civilwork engineering quantity, the gate of oblique keying can be set.Oblique open-close sluice gate can be applied to oblique pull transfer crane.Oblique pull transfer crane vertically has certain angle due to load Impact direction, certain horizontal pull can be produced to the dolly of transfer crane, the dolly of transfer crane designs routinely and relies on wheel and interorbital friction force to the problem driving the walking operation of dolly can there is skidding, and hoisting crane will be made to carry out oblique pull operation.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of oblique pull safety of gantry crane formula walking system for above-mentioned Problems existing, gantry crane trolley can be driven normally to walk, monkey is made to bear in the optional position of walking the lateral pull having certain angle with track, and in the horizontal direction automatic safe locking is carried out to monkey, ensure that monkey can carry out oblique pull operation at an arbitrary position, improve oblique pull transfer crane reliability of operation and safety.
The technical scheme that the utility model adopts is: a kind of oblique pull safety of gantry crane formula walking system, monkey is arranged on two tracks on oblique pull gate type portal gantry top by wheel assembly, it is characterized in that: bottom described monkey one end, connect two self locking type screw rod machines by hinged connecting device, be connected with synchronizing shaft device between two self locking type screw rod machines, described self locking type screw rod machine is fixed through the door frame of support and oblique pull transfer crane.
Described self locking type screw rod machine is the driving device of the bidirectional-movement done with auto-lock function.
The beneficial effects of the utility model are: the utility model provides new technical scheme for the hoofing part of oblique pull gantry crane trolley, the hoofing part technical scheme of this utility model overcome oblique pull gantry crane trolley design routinely rely on wheel and interorbital friction force to drive carriage walking run existing for slippage problems, can make oblique pull gantry crane trolley when bear compared with still can do when large horizontal force horizontal both direction walking run, and be all in installation lock-out state when dolly is worked at an arbitrary position, improve the safety in operation of equipment.Be provided with mechanical synchronizer between two actuating devices of this utility model, the wheel walking of dolly both sides run synchronous, steady, decrease the possibility in wheel gnawing rail road, improve equipment reliability of operation.This utility model has certain technology, economy and social benefit.
Accompanying drawing explanation
Fig. 1 is elevational view of the present utility model.
Fig. 2 is plan view of the present utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the monkey 1 of the present embodiment is arranged on two tracks 6 on oblique pull gate type portal gantry top by wheel assembly 5, the bottom, one end (afterwards) of described monkey 1 connects two self locking type screw rod machines 3 by hinged connecting device 2, be connected by synchronizing shaft device 7 between two self locking type screw rod machines, can synchronized operation be ensured.
Described two self locking type screw rod machines 3 are fixed through the door frame of support 4 with oblique pull transfer crane respectively.This self locking type screw rod machine 3 also has auto-lock function and can make bidirectional-movement.
When self locking type screw rod machine 3 operates, the screw column of himself will make horizontal motion (tandem motion), and drive monkey 1 to move horizontally on track 6 by hinged connecting device 2.Self locking type screw rod machine 3 can positive and negative both direction operate, therefore monkey 1 can be driven to move along walking in a horizontal state track 6 being done former and later two directions.Be provided with synchronizing shaft device 7 between two self locking type screw rod machines 3, make the running velocity mechanical synchronization of two self locking type screw rod machines 3, ensure that monkey 1 traveling comfort.Meanwhile, owing to being all in self-locking state when shutting down under self locking type screw rod machine 3 arbitrarily situation, being all in safe locking state when monkey 1 is worked at an arbitrary position, improve the safety in operation of monkey 1.
When the amount of capacity of self locking type screw rod machine 3 is run by monkey 1, maximum horizontal power is determined.
