Abstract
The utility model discloses a lifting hook limiting device of an electric hoist. The lifting hook limiting device of the electric hoist comprises photoelectric supports and photoelectric sensors, wherein the photoelectric sensors are arranged on the photoelectric supports and are in signal connection with a motor to control start and stop of the motor of the electric hoist. The photoelectric supports and the photoelectric sensors are symmetrically arranged on two sides of a lifting hook at the bottom of the electric hoist, wherein the photoelectric sensors are arranged in a bijection mode. Due to the fact that the two bijection photoelectric sensors are used for detecting the position of the lifting hook, the lifting hook limiting device of the electric hoist can effectively confirm the upper limit position of the lifting hook, protect the electric hoist against damage caused by out of control of the lifting hook, and avoid damage of equipment and safety accidents.
Description
Technical field
The utility model relates to a kind of inhibiting device, is specifically related to a kind of electric block suspension hook inhibiting device.
Background technology
Electric block lifts by crane as weight and equips in the lifting operation that has been applied in the various fields.In use often find the suspension hook of electric block bottom because motor bump out of control damages the phenomenon of electric block.Discover that general electric block has the device that rotates by the position control motor that detects steel rope, and this device mostly is the mechanical stroke switch, motor reason out of control then causes because of the travel switch cisco unity malfunction.Whether travel switch normally can't anticipation, causes taking place device damage accident and industrial accident, influences ordinary production.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of anticipation and easy to adjust, the spacing suspension hook of electric block accurately inhibiting device of shifting to an earlier date is provided.
A kind of electric block suspension hook inhibiting device, comprise the photoelectricity support, on the described photoelectricity support opto-electronic pickup that is connected, controls the start and stop of electric block motor with the motor signal is installed, described photoelectricity support and opto-electronic pickup symmetry are installed in the both sides of electric block bottom suspension hook, and described opto-electronic pickup is the correlation setting.
Described opto-electronic pickup position on the photoelectricity support is adjustable.
The utility model detects the suspension hook position by two correlation opto-electronic pickups, can effectively determine the suspension hook upper limit position, prevents suspension hook damage electric block out of control, has avoided the generation of device damage and safety misadventure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for explanation the present invention but not for limiting the scope of the invention.
Referring to Fig. 1, a kind of electric block suspension hook inhibiting device that the utility model provides, comprise photoelectricity support 1, the opto-electronic pickup 2 that is connected, controls the motor start and stop with the motor signal is installed on the described photoelectricity support 1, described photoelectricity support 1 and opto-electronic pickup 2 symmetries are installed in the both sides of electric block 3 bottom suspension hooks 4, described opto-electronic pickup 2 is the correlation setting, and the position is adjustable on photoelectricity support 1.
Claims (2)
1. electric block suspension hook inhibiting device, it is characterized in that: comprise the photoelectricity support, on the described photoelectricity support opto-electronic pickup that is connected, controls the start and stop of electric block motor with the motor signal is installed, described photoelectricity support and opto-electronic pickup symmetry are installed in the both sides of electric block bottom suspension hook, and described opto-electronic pickup is the correlation setting.
2. a kind of electric block suspension hook inhibiting device according to claim 1, it is characterized in that: described opto-electronic pickup position on the photoelectricity support is adjustable.
