Abstract
The utility model discloses a groined frame position limiting device, which is characterized in that the groined frame position limiting device comprises a lever, a position limiting switch, a spring box and balance weight iron, wherein the left side of the lever is fixed on a support seat, the lever can do anticlockwise rotation around the support seat, the end part of the right side of the lever is provided with the balance weight iron, the position limiting switch and the spring box are arranged under the lever, the spring box is positioned at the right side of the position limiting switch, and the spring box is higher than the position limiting switch. The utility model has the advantages of compact structure and simple manufacture and installation process, and reduces the use cost of construction machines and the work intensity of maintenance workers.
Description
Technical field
The utility model relates to a kind of well cabinet frame inhibiting device, is applicable to the realm of building construction.
Background technology
In traditional well cabinet frame valve limit configuration, valve directly clashes into the contact of limit switch during the inhibiting device operation, because the vibratory force and the impulsive force of valve are bigger, cause limit switch very easily to damage, malfunctioning easily in work progress, must frequently change, not only increased cost, and the safety that is threatening the workmen, influence construction speed.
The utility model content
The technical matters that the utility model solves provides a kind of well cabinet frame inhibiting device, avoids valve direct service life of minimizing limit switch with limit switch contact bump.
The utility model comprises lever, limit switch, spring case, balance weight iron.The lever left side is fixed on the bearing, and lever can rotate counterclockwise around bearing, and the lever right-hand end is provided with balance weight iron, the lever below is provided with limit switch and spring case, spring case is positioned at the limit switch right side, and spring case is higher than limit switch, and balance weight iron at first contacted with lever when lever fell.
The utility model is valve bump lever when the inhibiting device operation, and lever rotates limit switch is disconnected.Valve leaves lever, and lever is self-return under the effect of balance weight iron, the limit switch closure.Valve does not have directly to clash into the contact of limit switch in the structure that the utility model provides, thereby has protected limit switch.The utility model utilizes spring case to cushion the pressure that lever imposes on limit switch, prevents lever crushing limit switch under the balance weight iron effect.
The utility model compact conformation, manufacturing and mounting process are simple, have reduced the labour intensity of the use cost and the service worker of construction machinery and equipment.
Description of drawings
A kind of well cabinet frame of Fig. 1 inhibiting device
1, valve, 2, lever, 3, limit switch, 4, spring case, 5 balance weight irons
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a kind of well cabinet frame inhibiting device.The utility model comprises lever 2, limit switch 3, spring case 4, balance weight iron 5.Lever 2 left sides are fixed on the bearing, lever 2 can rotate counterclockwise around bearing, lever 2 right-hand end are provided with balance weight iron 5, lever 2 belows are provided with limit switch 3 and spring case 4, spring case 4 is positioned at limit switch 3 right sides, spring case 4 is higher than limit switch 3, and balance weight iron 5 at first contacted with lever 2 when lever 2 fell.
Valve 1 effect of impact lever 2 when the inhibiting device operation, lever 2 rotates counterclockwise, and limit switch 3 disconnects; Valve 1 leaves lever 2, and lever is self-return under the effect of balance weight iron 5, and balance weight iron 5 at first acts on the spring case 4, is acting on the limit switch 3 then, and limit switch 3 occurs closed.The buffer action of spring case 4 has been protected limit switch 3 effectively.
