Description

Deviation correcting device with early warning feedback

Technical Field

The utility model relates to the technical field of cranes, in particular to a deviation correcting device with early warning feedback.

Background

Along with the rapid development of economy in China, the lifting and transporting equipment plays a great role in industrial production, and the lifting equipment is greatly improved in the aspects of functionality and safety.

The value of the deviation of the crane span is one of the important core parameters in the hoisting equipment. Because the large-span large-tonnage portal crane generally adopts a rigid leg structure and a flexible leg structure, and the flexible leg side is generally connected with the main beam in a spherical hinge or a column hinge, the phenomenon that the portal crane span is easy to cause larger deviation is caused. When the production work, if the span deviation is larger, the rigidity of the door machine is reduced, the rotating speed error of the running mechanism of the rail car at the two sides is increased, the rail gnawing appears, the operation efficiency is greatly reduced, and serious safety accidents are more caused.

Disclosure of Invention

In order to solve the problems, the utility model provides a deviation correcting device with an early warning signal feedback function, wherein the signal feedback device is arranged beside a flexible hinge.

The specific scheme is as follows:

the utility model provides a take deviation correcting device of early warning feedback, includes bottom plate and driving lever, fixed two fixed plates on the bottom plate, and the tip of every fixed plate all is equipped with an angle sensor, and angle sensor is equipped with the pivot on the bottom plate altogether four, and the pivot is vertical to be set up, and its overcoat is established the pointer, and the upper surface of pointer is equipped with the recess, and it can revolute the pivot and rotate, and each side of pointer is equipped with two angle sensor, fixes the ejector pin on the driving lever, and the lower extreme of ejector pin is inserted in the recess.

The angle sensor is rotationally connected to the end part of the bolt, the bolt is in threaded fit with the nut, and the nut is fixed on the fixed plate.

The edge of the bottom plate is fixed with a graduated scale.

A shaft sleeve is arranged between the rotating shaft and the pointer, and the shaft sleeve is sleeved outside the rotating shaft.

The beneficial effects are that: compared with the prior art, the angle sensor is arranged, and when the spans of the flexible leg and the rigid leg deviate, the pointer of the device can swing left and right along with the deviation direction. When the pointer swings to a preset early warning position, the system gives out a warning. When the preset limit is reached, the system can force the equipment to stop in order to ensure safety.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.

As shown in fig. 1-3, a deviation correcting device with early warning feedback comprises a bottom plate 20 and a deflector rod 1, wherein two fixing plates 21 are fixed on the bottom plate 20, an angle sensor 6 is arranged at the end part of each fixing plate 21, and the number of the angle sensors 6 is four.

The rotary shaft 3 is arranged on the bottom plate 20, the rotary shaft 3 is vertically arranged, the pointer 2 is sleeved outside the rotary shaft 3, the upper surface of the pointer 2 is provided with a groove 8, the rotary shaft can rotate around the rotary shaft 3, each side of the pointer 2 is provided with two angle sensors 6, the push rod 7 is fixed on the deflector rod 1, and the lower end of the push rod 7 is inserted into the groove 8.

In order to facilitate the adjustment of the position of the angle sensor 6 and to control the dimension of "alarm caused by deviation in door span", the angle sensor 6 is rotatably connected to the end of the bolt 62, the bolt 62 is screwed with the nut 61, and the nut 61 is fixed to the fixing plate 21. Thus, when the nut end of the bolt 62 is turned, the distance from the angle sensor 6 to the pointer 2 is adjusted.

For convenient observation, the graduated scale 5 is fixed at the edge of the bottom plate 20, and personnel can clearly observe the direction and degree of deflection through the dial plate, so that correction is convenient to temporarily perform.

For convenient rotation, a shaft sleeve 31 is arranged between the rotating shaft 3 and the pointer 2, and the shaft sleeve 31 is sleeved outside the rotating shaft 3.

The working principle is as follows:

and (2) mounting:

the flexible hinge is arranged beside the flexible hinge, and specifically comprises: the deflector rod 1 is fixed on the main beam, and the bottom plate 20 is fixed on the flexible leg.

The method comprises the following steps:

when the main beam swings, the deflector rod 1 and the ejector rod 7 synchronously swing, the ejector rod 7 dials the pointer 2 to rotate around the rotating shaft 3 through the groove 8, when the pointer 2 rotates for a certain angle, the pointer 2 can touch the probe 63 of the angle sensor 6, see fig. 4, if the pointer 2 rotates anticlockwise, the pointer 2 can squeeze the angle sensor 6 at the lower left corner or/and the upper right corner, the probe 63 of the angle sensor 6 can rotate around the pin shaft 64, when the probe 63 rotates for a certain angle, the system enters an early warning or stopping state, and the specific value of the early warning or stopping is set according to specific conditions.

When the pointer 2 is located at the standard position, the distance from the probe 63 to the pointer 2 needs to be adjusted, and the adjustment can be performed through the bolts 62 and the nuts 61, so that the specific value of the early warning or stopping can be adjusted according to the specific situation.
