Abstract
The utility model provides a promote reflection-type grating detection device that dolly was used, it is including detecting grating, reflecting plate, transmission cable, wherein, dolly bottom both ends are fixed with the mounting panel, and the mounting panel of every one end is two, is located dolly bottom both sides respectively, wherein installs the detection grating on the mounting panel of one end, installs the reflecting plate on the mounting panel of the other end, and the detection grating uses with the reflecting plate cooperation, and transmission cable one end is connected with the detection grating, and the other end inserts external control system. The cost after this scheme of adoption is low, the installation is simple, the signal is reliable.
Description
Technical Field
The utility model belongs to the technical field of the hoisting trolley technique and specifically relates to indicate the reflection-type grating detection device that the hoisting trolley used.
Background
The loop lifting trolley runs at the top of the loop, because the top is not provided with deviation rectifying detection and correction equipment, sometimes when strip steel on the trolley deviates from a central line seriously, due to the height problem, a strip steel centering detection device arranged at the bottom of the loop cannot reflect the deviation condition of the strip steel of the trolley at the top in time, the control system cannot identify the serious condition of the deviation of the strip steel at the top, the early warning cannot be made on the deviation of the strip steel at the top, an operator cannot monitor the steel structure condition of the trolley in which the strip steel scrapes on the trolley at the top in time, the strip steel breakage risk is caused, and thus serious production accidents can occur.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, provide a cost that promotes the dolly and hang down, the installation is simple, the reliable reflection-type grating detection device of signal.
In order to achieve the above object, the present invention provides a technical solution: promote reflection-type grating detection device that dolly was used, it is including detecting the grating, reflecting plate, transmission cable, wherein, dolly bottom both ends are fixed with the mounting panel, and the mounting panel of every one end is two, is located dolly bottom both sides respectively, installs the detection grating on the mounting panel of one end wherein, installs the reflecting plate on the mounting panel of the other end, detects the grating and uses with the reflecting plate cooperation, and transmission cable one end is connected with the detection grating, and the other end inserts external control system.
The middle part of the transmission cable is hung on one side of the bottom of the trolley in a U-shaped free falling mode.
The reflecting plates on the mounting plates are two, and one reflecting plate is mounted on the same mounting plate.
The mounting plate is made of an F-shaped clamp, and the reflecting plate is bonded or fixed on the lower part of the vertical arm of the F-shaped clamp through a bolt.
After the scheme is adopted, the reflection-type grating is arranged at the lower part of the trolley, in order to overcome the influence of vibration on the optical line, the double reflection plates are adopted to reflect the light source, when the trolley is ensured to vibrate, the grating can accurately receive the reflection signal, in order to connect the sensor signal moving together with the movable trolley into the control system, a single 20 x 1 core flexible flat cable is adopted to be laid into a U-shaped free-falling body rolling shape, and a mobile cable is formed to transmit signals; the steel strip detection device moves along with the trolley after being installed, whether the steel strip is close to the steel structure of the trolley structure is measured in real time, and whether the steel strip of the trolley at the top of the loop is in contact with the steel structure of the trolley is monitored in real time through the control system; the cost after this scheme of adoption is low, the installation is simple, the signal is reliable.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to fig. 1, the reflection-type grating detection device for a lift truck according to this embodiment includes a detection grating 1, a reflection plate 2, and a transmission cable 3, wherein, two mounting plates 4 are fixed at two ends of the bottom of the trolley, the two mounting plates 4 at each end are respectively positioned at two sides of the bottom of the trolley, wherein install on the mounting panel 4 of one end and detect grating 1, install reflecting plate 2 on the mounting panel 4 of the other end, mounting panel 4 adopts F shape clamp to make, reflecting plate 2 bonds or passes through the vertical arm lower part of bolt fastening at F shape clamp, reflecting plate 2 on the mounting panel 4 is two, install on same mounting panel 4 one on the other, it uses with the cooperation of reflecting plate 2 to detect grating 1, 3 one ends of transmission cable are connected with detection grating 1, the other end inserts external control system, 3 middle parts of transmission cable are the mode of the free fall of U type and hang in dolly bottom one side.
In the embodiment, the reflection-type optical grating is arranged at the lower part of the trolley, a double-reflection plate is adopted to reflect the light source in order to overcome the influence of vibration on an optical line, so that the optical grating can accurately receive a reflection signal when the trolley vibrates, and a single 20 x 1 core flexible flat cable is laid into a U-shaped free-falling body rolling shape in order to connect a sensor signal moving together with the movable trolley into a control system, so that a moving cable pair is formed to transmit the signal; the steel strip detection device moves along with the trolley after being installed, whether the steel strip is close to the steel structure of the trolley structure is measured in real time, and whether the steel strip of the trolley at the top of the loop is in contact with the steel structure of the trolley is monitored in real time through the control system; the manufacturing cost after the embodiment is adopted is low, the installation is simple, and the signal is reliable.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
