Description

Spacing canceling release mechanical system of rocking arm

Technical Field

The utility model relates to a spacing technical field of track especially relates to a spacing canceling release mechanical system of rocking arm.

Background

The crane's cart track must be fixed on the travel beam, and the dolly track is fixed on the main beam. When the crane runs and works, the rail cannot move transversely and longitudinally, and the rail is convenient to adjust. Rocking arm stop device is installed to cart track tip, and the rocking arm is spacing through hitting chi repeated collision, and the phenomenon that inside card shell takes place not return hits the chi and often appears the dislocation, rub spacingly when colliding easily, causes spacing damage, shortens life, incremental cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving among the prior art that the rocking arm stop device resilience force is not enough, resilience cycle overlength causes the shortcoming that inside spring damaged inefficacy easily through the collision for a long time, and the spacing canceling release mechanical system of rocking arm that proposes.

In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides a spacing canceling release mechanical system of rocking arm, includes the track, track one end welding has the baffle, and track top card is equipped with hits the chi, hit chi one end welding and have the contact plate, and track one side welding has the mount pad, surface mounting has the rocking arm stopper on the mount pad, rocking arm stopper response end has cup jointed the rocking arm, the welding of rocking arm top outside has the contact piece, the welding of baffle one side has the mounting panel, mounting panel one side swing joint has the telescopic link, the inboard welding in telescopic link bottom has the spring.

Preferably, one end of the telescopic rod is movably connected with the rocker arm through a pin shaft.

Preferably, the bottom of the contact plate is provided with a clamping groove matched with the rail.

Preferably, the contact block is located outside one side of the contact plate.

Preferably, the mounting plate is movably connected with the telescopic rod through a pin shaft.

The utility model has the advantages that:

the device can effectively increase the resilience force to reduce the swing arm jamming, reduce the difficult problem that the cart resets that causes because of the swing arm not return, increased the life of rocking arm stopper simultaneously.

Drawings

Fig. 1 is a schematic structural view of a rocker arm limiting and resetting mechanism provided by the present invention;

fig. 2 is a schematic view of a top view structure of the rocker arm limiting and resetting mechanism provided by the present invention.

In the figure: 1. a track; 2. a baffle plate; 3. a collision ruler; 4. a contact plate; 5. a mounting seat; 6. a rocker arm stop; 7. a rocker arm; 8. a contact block; 9. mounting a plate; 10. a telescopic rod; 11. a spring.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a spacing canceling release mechanical system of rocking arm, including track 1, the welding of 1 one end of track has

baffle

2, 1 top card of track is equipped with hits chi 3, hit chi 3 one end welding has contact plate 4, the welding of 1 one side of track has mount pad 5, surface mounting has rocking arm stopper 6 on the mount pad 5, rocking arm 7 has been cup jointed to rocking arm stopper 6 response end, the welding of 7 top outsides of rocking arm has contact block 8, the welding of 2 one sides of baffle has mounting panel 9, mounting panel 9 one side swing joint has telescopic link 10, the inboard welding of telescopic link 10 bottom has spring 11.

One end of a telescopic rod 10 is movably connected with the rocker arm 7 through a pin shaft, a clamping groove matched with the rail 1 is formed in the bottom of the contact plate 4, the contact block 8 is located outside one side of the contact plate 4, and the mounting plate 9 is movably connected with the telescopic rod 10 through a pin shaft.

In this embodiment, when the striking scale 3 slides on the track 1 to the end of the track 1, the contact plate 4 may strike the contact block 8 on the outer side of the top of the rocker arm 7, so that the rocker arm 7 rotates to drive the sensing end of the rocker arm stopper 6 to rotate, and a reaction force is generated on the contact plate 4 under the action of the rebounding device inside the rocker arm stopper 6 to assist in resetting the striking scale 3.

Further, one side welding mounting panel 9 at baffle 2, and through round pin axle swing joint telescopic link 10 in the inboard of mounting panel 9, the inboard welding spring 11 of telescopic link 10, telescopic link 10 one end is through round pin axle swing joint with rocking arm 7, like this when rocking arm 7 pressurized is rotatory, can produce pressure to telescopic link 10, thereby make telescopic link 10 extrusion deformation, cause spring 11 to deform, like this spring 11 produces the reaction force to rocking arm 7, accelerate the reseing of rocking arm 7, produce bigger thrust to touch panel 4.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
