Description
Technical field
The utility model relates to a kind of braking mechanism, particularly relates to a kind of intelligent brake self-locking and release mechanism.
Background technology
In a lot of fields, especially engineering machinery field, as stake machine, dynamic compaction machinery construction etc., often needing to use free off the hook elevator does the action rammed, and namely mentions hammer ram, brake is stepped on after arriving certain altitude, then close clutch, make elevator be in free state, then get off the brakes, hammer ram just falls, and completes and rams action.
General brake gear does not all have self-locking and unlocking function, and this braking mechanism is held by operator completely when ramming action, there is larger danger; Other does not generally detect the function whether checked with the braking mechanism of self-locking and unlocking function yet, and this rams action for this, particularly more dangerous for the action frequently rammed.
Utility model content
Technical problem to be solved in the utility model is to provide one and can detects with or without self-locking and feed back signal to system, when the non-self-locking of brake gear being detected, the signal of feedback can limit the action of clutch, safe and reliable intelligent brake self-locking and release mechanism.
In order to solve the problems of the technologies described above, the intelligent brake self-locking that the utility model provides and release mechanism, comprise brake gear, described brake gear comprises brake pedal, brake gear base and back-moving spring, determine pawl to be fixedly connected with described brake gear base, pawl is hinged on twisted seat, described twisted seat is fixedly installed on described brake pedal, described pawl is connected with unblock pedal, described pawl is provided with return spring, the detecting sensor communicated to connect with control system is installed on described determines on pawl, described pawl and described determine pawl and hook the detecting sensor described in touching when closing.
Described return spring is between described pawl and described twisted seat.
Described brake pedal has a through hole, described unblock pedal is connected with described pawl through described through hole.
Adopt intelligent brake self-locking and the release mechanism of technique scheme, its operating principle is: when stepping on brake pedal and arriving certain position, determine pawl can promote pawl around the pin joint of twisted seat and turn clockwise, under the elastic force effect of return spring, pawl and the conjunction of pawl hook is determined when arriving certain position again, realize brake self-locking, now detecting sensor can detect that the hook determining pawl and pawl closes; Unlock pedal and make to determine pawl by stepping on and is separated with pawl again, realize unblock simultaneously under the effect of brake pedal back-moving spring, now detecting sensor can detect and determine being separated of pawl and pawl.
The utility model has the advantages that: structure is simple, brake self-locking is reliable, can detect with or without self-locking and feed back signal to system, and when the non-self-locking of brake gear being detected, the signal of feedback can limit the action of clutch etc., safe and reliable.
Accompanying drawing explanation
Fig. 1 is for when stepping on brake pedal and arriving certain position, and determining pawl can contact with pawl, the state diagram that promotion pawl turns clockwise around the pin joint of twisted seat.
When Fig. 2 is for continuing to step on brake pedal arrival certain position, determine pawl and the conjunction of pawl hook under the elastic force effect of spring, realize the state diagram of brake self-locking, now detecting sensor can detect the hook conjunction determining pawl and pawl.
Fig. 3 steps on to unlock pedal and make to determine the state diagram that pawl is separated with pawl, now under the effect of brake pedal back-moving spring, realizes unblock.
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing.
See Fig. 1, Fig. 2 and Fig. 3, brake gear 1 comprises brake pedal 1-1, brake gear base 1-2 and back-moving spring 1-3, determine pawl 2 to be fixedly connected with brake gear base 1-2, pawl 3 is hinged on twisted seat 5, twisted seat 5 is fixedly installed on brake pedal 1-1, and pawl 3 is connected with and unlocks pedal 4, pawl 3 is provided with return spring 6, the detecting sensor 7 communicated to connect with control system is installed on determines on pawl 2, and pawl 3 is determined pawl 2 and hooked when closing with described and can touch detecting sensor 7.
Particularly, return spring 6 is between pawl 3 and twisted seat 5.
Particularly, brake pedal 1-1 has a through hole 8, unlock pedal 4 and be connected with pawl 3 through through hole 8.
See Fig. 1, Fig. 2 and Fig. 3, when stepping on brake pedal 1-1 and arriving certain position, determine pawl 2 and can promote the resistance that pawl 3 overcomes return spring 6 and turn clockwise around the pin joint of twisted seat 5.Return spring 6 is between pawl 3 and twisted seat 5, and the elastic force of return spring 6 can make pawl 3 be rotated counterclockwise around the pin joint of twisted seat 5, provides power for pawl 3 is closed with the hook determining pawl 2.
When pawl 3 is closed with the hook determine pawl 2, namely brake self-locking time, detecting sensor 7 can sense pawl 3, to the control system feedback signal of main frame, when pawl 3 is with when determining being separated of pawl 2, can detect and feed back the signal of unblock of braking.
Brake pedal 1-1 has a through hole 8, unlock pedal 4 to be connected with pawl 3, and coupling part is through this through hole 8, steps on and unlock pedal 4 until when the soffit of unblock pedal 4 contacts with the upper surface of brake pedal 1-1, pawl 3 with determine pawl 2 and be separated, realize brake and unlock.
The type of return spring 6 is not limit.The type of detecting sensor 7 is not limit.
Use procedure of the present utility model is: as shown in Figure 1, when stepping on brake pedal 1-1 and arriving certain position, determines pawl 2 and can promote pawl 3 around the pin joint of twisted seat 5 and turn clockwise; Again as shown in Figure 2, determining pawl 2 and the conjunction of pawl 3 hook under the elastic force effect when continuing to step on brake pedal 1-1 arrival certain position at return spring 6, realizing brake self-locking, now detecting sensor 7 can detect the hook conjunction determining pawl 2 and pawl 3; Again as shown in Figure 3, unlocking pedal 4 and make to determine pawl 2 and be separated with pawl 3, now realizing unlocking under the effect of brake pedal back-moving spring 1-3 by stepping on, now detecting sensor 7 can detect and determine being separated of pawl 2 and pawl 3.
The foregoing is only preferred embodiment of the present utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
