The utility model discloses a two gear wheels and matching section motivation are constructed and are connected, and the telescoping device relies on reliable electricity, liquid control system, controls simple mechanical linkage device, has realized the mechanical linkage of two hoists to fine realization transferring in step of two hoists. Implement synchro control device is transferred to unloaded hook that freely falls of two hoists except installing solenoid valve, hydraulic cylinder and simple mechanical mechanism additional, need not additionally to increase other hardware and just can realize transferring in step of hoist, great promotion work efficiency.
Description
Technical field
The utility model belongs to winch field, relates in particular to the unloaded free off the hook of a kind of double hoisting and transfers sync control device.
Background technology
In order to increase work efficiency, realize transferring fast of elevator, operationally operator is often through opening elevator power-transfer clutch, and make elevator be in free off the hook and transfer state, suspension hook is free releasing under gravity.Transfer compared to power, this state lowering velocity is faster.Because under free off the hook state, elevator is stressed smaller, elevator lowering velocity under state is transferred in free off the hook of same model is very large with the relation of friction force, and manufacturing errors is different with the friction force that rope stretching angle produces, and causes speed difference huge.Only overcome the impact of differentiated friction power on elevator lowering velocity, just can reach the object of forced synchronization.Technology report also not relevant at present.
Utility model content
The purpose of this utility model is to overcome the problems referred to above, provide the unloaded free off the hook of a kind of double hoisting and transfer sync control device, be the interlock sync control device of complete set, when free releasing, two elevator interlocks got up, reach the object of forced synchronization.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Sync control device is transferred in the unloaded free off the hook of a kind of double hoisting, comprise be installed on two volume axle drive shaft in big gear wheel and synchronous interaction mechanism, synchronous interaction mechanism is connected with two big gear wheels, and synchronous interaction mechanism is arranged in frame by retractor device.
Described synchronous interaction mechanism is linkage gear, and linkage gear is arranged in the frame of two big gear wheel the same sides by retractor device, and synchronous interaction gear engages each other with two big gear wheels after stretching out.
Described retractor device is hydraulic ram pushing mechanism, and linkage gear is located at the piston rod end of hydraulic ram pushing mechanism, and can rotate by axle centered by piston rod.
Described hydraulic ram pushing mechanism comprise connect successively hydraulic ram, hydraulic buttery valve and Hydraulic Pump and the master cock that is connected with oil cylinder hydraulic electromagnetic valve, linkage gear is arranged on the piston rod end of hydraulic ram.
Adopt technique scheme, the utility model has following advantage: the utility model is connected with synchronous interaction mechanism by two big gear wheels, retractor device relies on failure-free electricity, liquid control system, control simple mechanical linkage, achieve the mechanical linkage of two elevators, thus well achieve synchronously transferring of two elevators.Implement the unloaded free off the hook of double hoisting and transfer sync control device except installing electromagnetic valve, hydraulic ram and simple mechanical mechanism additional, just can realize synchronously transferring of elevator without the need to additionally increasing other hardware, improving work efficiency greatly.

Fig. 1 is the synchronous schematic diagram of elevator that sync control device is transferred in the free off the hook of the utility model double hoisting;
Fig. 2 is the schematic diagram that sync control device is transferred in the free off the hook of the utility model double hoisting.
Fig. 3 is the utility model using state reference diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail
Sync control device is transferred in the unloaded free off the hook of a kind of double hoisting as shown in Figure 1-Figure 3, comprise be installed on two volume 1,2 axle drive shafts in big gear wheel 3,4, two elevators are meshed together by linkage gear 5, ensure that the synchronous of two elevators just by this mechanical transmission structure.
As shown in Figures 2 and 3, linkage gear 5 is fixed in the frame of two big gear wheel the same sides by hydraulic telescopic device, retractor device is hydraulic ram pushing mechanism, described hydraulic ram pushing mechanism comprise connect successively hydraulic ram 6, hydraulic buttery valve 7 and Hydraulic Pump 9 and the master cock 8 that is connected with oil cylinder hydraulic electromagnetic valve, hydraulic ram is installed in the frame of two big gear wheel the same sides, linkage gear is located at the piston rod end of hydraulic ram, and linkage gear can rotate by axle centered by piston rod.Hydraulic buttery valve, Hydraulic Pump and master cock can be arranged on any position of double hoisting frame according to actual condition, handled easily just can.
The whole control setup of the utility model is made up of parts such as mechanical electronic hydraulic.There is provided driving power by Hydraulic Pump, electric part is responsible for the control of action, and mechanics is as the actuating unit of whole system.By master cock, the break-make of Controlling solenoid valve realizes the switching of hydraulic circuit.And hydraulic ram completes expanding-contracting action under the promotion of hydraulic oil, thus control the motion of link gear, namely control linkage gear and engage with two big gear wheels.Under the control of link gear, two elevators can realize single movement or synchronous axial system.When engaging with two big gear wheels when linkage gear stretches out, two elevator synchronous axial system, when linkage gear is retracted, away from two big gear wheels, then can realize the single movement of two elevators.
Two elevator actvies, by a set of failure-free link gear, mesh together, realize synchronous axial system when two elevators are transferred by the utility model; Hydraulic ram pushing mechanism, controls the action of link gear, makes link gear action on request; Hydraulic buttery valve, flexible by the break-make hydraulic control oil cylinder of hydraulic control oil; Master cock, the break-make of Controlling solenoid valve; Wherein electromagnetic valve is coupled together by hydralic hose and hydraulic ram, Hydraulic Pump, is provided the power promoting link gear and move by Hydraulic Pump; Master cock is by electric wire connected electromagnetic valve.
The utility model passes through the break-make of master cock 8 Controlling solenoid valve 7, to realize the flexible of hydraulic ram 6.The flexible drive linkage gear 5 of hydraulic ram 6 moves, and by linkage gear 5, the big gear wheel 3,4 be contained in respectively on two elevators is engaged.Due to free off the hook transfer state under the load that is carried on elevator very little, so can not impact system.And the different friction drag suffered by two elevators can be overcome by gears meshing, the object of two elevator synchronous axial system can be reached.
