The specific embodiment
Below in conjunction with schematic diagram and concrete operations embodiment the present invention is described further.
Fig. 1 is that a kind of main amplitude mast of the present invention is received the scheme drawing in the specific embodiment that rop exercise makes device; Fig. 3 is an A place enlarged drawing among Fig. 1; As shown in figures 1 and 3, a kind of main amplitude mast of the embodiment of the invention is received rop exercise and is made device, includes a platform 1; The afterbody of the hinged main amplitude mast 2 of the stem of platform 1; One rope withdrawing apparatus 3 is installed in the centre of platform 1, and this rope withdrawing apparatus 3 is connected with the afterbody of main amplitude mast 2 through rope, makes that receiving rope through the elevator of rope withdrawing apparatus 3 makes the afterbody of main amplitude mast 2 to rotate around the stem of platform 1.Afterbody at platform 1 is equipped with a rig bracket 4, and this rig bracket 4 has a limit switch 5 as fender guard, and this limit switch 5 is over against the afterbody of main amplitude mast 2.Simultaneously; Limit switch 5 also comprises and is connected with a controller (not shown); If main amplitude mast 2 has forwarded installed platform carriage 4 to through rope withdrawing apparatus 3; And the afterbody of main amplitude mast 2 is pressed on the limit switch 5, and limit switch 5 backs are passed to external OPS through controller with the signal feedback of accomplishing.If operator's this moment still continues to receive rope through rope withdrawing apparatus 3, then limit switch 5 will be done to continue operation in order to the restriction operation person.
Among first embodiment of this embodiment, Fig. 2 is that a kind of main amplitude mast of the present invention is received the scheme drawing that rig bracket in the device is made in rop exercise, please continue like Fig. 1, Fig. 2 and shown in Figure 3.Concrete, weld a rig bracket 4 respectively at the right and left of platform 1 afterbody, this rig bracket 4 is a box-structure.Rig bracket 4 includes a back vertical plate 41; Upside at back vertical plate 41 is connected with a mounting plate 42; It is own that mounting plate 42 is mainly used in picking-up main amplitude mast 2; The afterbody of the center of mounting plate 42 and main amplitude mast 2 matches, and guarantees that main amplitude mast 2 can be in horizontal installation site evenly.Simultaneously, be used to install limit switch 5 on the mounting plate 42.Connect an oblique riser 43 respectively in the left and right sides of back vertical plate 41, the gradient of this oblique riser 43 extends to platform 1 always from the top of platform 1 base plate carries weight power effectively with this.Rig bracket 4 also includes a brace panel 44, makes two oblique risers 43 to be coupled together and to play the effect of reinforcement through brace panel 44 and back vertical plate 41, and simultaneously, brace panel 44 is connected with the afterbody of platform 1, with this rig bracket 4 is soldered on the platform 1.The height of rig bracket 4 structures and width are confirmed through optimal design method, to guarantee simplifying of structure itself.The version of rig bracket 4 is carried the pressure from main amplitude mast 2 effectively, and main amplitude mast 2 is put on Stress Transfer to the platform 1 on the rig bracket 4, thereby avoids rig bracket 4 itself not add by conquassation because of bearing capacity.
Among second embodiment of this embodiment, also include an annunciator (not shown), and this annunciator is controlled by controller.When the afterbody of main amplitude mast 2 is fallen 4 last times of rig bracket, limit switch 5 is sensed main amplitude mast 2 and has been reclaimed and put in place, then sends warning through controller control annunciator, caution operator shut-down operation.
Among the 3rd embodiment of this embodiment, above-mentioned controller can also connect a hydraulic electric control system (not shown).When the afterbody of main amplitude mast 2 is fallen 4 last times of rig bracket, limit switch 5 is sensed main amplitude mast 2 and has been reclaimed and put in place, and simultaneously, the operator who limits in the external operator's compartment through controller modulated pressure electric-control system continues to receive rope to rope withdrawing apparatus 3.
The present invention is owing at platform 1 afterbody erecting stage carriage 4, through increasing the mode of platform 1 arm of force, improve the load-carrying capacity of rig bracket 4 effectively.When the afterbody of main amplitude mast 2 finally drops on the rig bracket 4; Main amplitude mast 2 is in installing condition and rope withdrawing apparatus 3 continuation effects receipts rope; Cause the hoist motor maxim that builds the pressure, it is maximum that the lift rope pulling force reaches, and the extension position of the arm of force is confirmed according to the force analysis of this moment.
Among the further embodiment of this embodiment, limit switch 5 can adopt modes such as angle limit switch, contact limit switch to replace.
Among the further embodiment of this embodiment; The mode that the restriction operation person continues to reclaim the hydraulic electric control system of main amplitude mast 2 operations also can adopt other approach, as: limit switch 5 signals connect controller, and controller is connected to the hydraulic efficiency pressure system of rope withdrawing apparatus 3 hoist motors action again through modes such as electromagnetic valves; After main amplitude mast 2 puts in place; Closed electromagnetic valve, the flow of hydraulic efficiency pressure system is closed, and elevator stops rope stretching.
Among the further embodiment of this embodiment, the structure of above-mentioned rig bracket 4 also can adopt other difformities.
More than present embodiment is described in detail, but present embodiment is not restricted to the specific embodiment of above description, it is just as example.To those skilled in the art, any equivalent modifications and alternative also all among the category of present embodiment.Therefore, impartial conversion and the modification under spirit that does not break away from present embodiment and scope, done all should be encompassed in the scope of present embodiment.
