Abstract
The utility model discloses a safety system of a scraper material taking arm, which comprises the scraper material taking arm. The scraper material taking arm comprises a first sprocket (2), a second sprocket (3), two chains (6) and scrapers (4), wherein the first sprocket (2) and the second sprocket (3) are arranged at two ends of a suspension arm, the two chains (6) are arranged at two ends of the sprockets, and the scrapers (4) are arranged on the chains (6). A sensing protrusion (5) is arranged at the same position on each scraper (4), and a proximity switch (1) is arranged on the side of the sensing protrusion (5) and connected to a programmable logic controller (PLC). A motor (7) is connected onto the first sprocket (2) and connected with the PLC. When problems such as blocking happen to the scrapers, working of the motor can be basically stopped, and the machine is not easily damaged.
Description
Technical field
The utility model relates to a kind of safety system, especially relates to the scraper plate arm for taking material safety system on a kind of scraper reclaimer.
Background technology
Do not have safety device on the scraper plate arm for taking material of traditional screeds reclaimer, when problems such as scraper plate generation jam, if also continue running, machine damages easily.
The utility model content
The utility model does not have the problem of safety control for the arm for taking material that solves present scraper reclaimer; A kind of scraper plate arm for taking material safety system is provided for this reason; Comprise the scraper plate arm for taking material; Said scraper plate arm for taking material comprises two chains 6 at first sprocket wheel 2, second sprocket wheel 3 at cantilever two ends, two sprocket wheel two ends and the scraper plate 4 on the chain 6, is equipped with an induction projection 5 on the same position of each scraper plate 4, and the side of induction projection 5 is provided with one near switch 1; Be connected on the PLC (Programmable Logic Controller, programmable logic controller (PLC)) near switch 1; Be connected with a motor 7 on said first sprocket wheel 2, motor 7 is connected with PLC.
The utility model scraper plate arm for taking material safety system, the distance between the said every scraper plate 4 equates.
The utility model scraper plate arm for taking material safety system does not saidly contact with the scraper plate arm for taking material near switch 1.
The utility model is like this operation: before the operation of scraper plate arm for taking material, be decided to be a fixed value with the rotating speed of sprocket wheel is preset, make its motion that remains a constant speed.During operation, sprocket wheel drives chain and rotates, and the induction projection on the scraper plate is along with motion, because the distance between the induction projection equates that each induction projection equated through the time near switch.When problem such as getting stuck, two adjacent induction projections through near the time of switch unequal, after PLC obtained signal, the control motor quit work.
The beneficial effect of the utility model is:
Owing on the scraper plate arm for taking material of scraper reclaimer, added a safety system, therefore when problems such as old-fashioned and inflexible generation jam, can control machine to quit work, make machine not fragile.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the scheme drawing of the utility model;
Fig. 2 is the scheme drawing of the utility model middle scraper arm for taking material.
The specific embodiment
Disclosed all characteristics in this specification sheets, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
Scraper plate arm for taking material safety system as depicted in figs. 1 and 2; Comprise the scraper plate arm for taking material; Said scraper plate arm for taking material comprises two chains 6 at first sprocket wheel 2, second sprocket wheel 3 at cantilever two ends, two sprocket wheel two ends and the scraper plate 4 on the chain 6, and the distance between the said every scraper plate 4 equates, is equipped with an induction projection 5 on the same position of each scraper plate 4; The side of induction projection 5 is provided with one near switch 1, is connected on the PLC near switch 1; Be connected with a motor 7 on said first sprocket wheel 2, motor 7 is connected with PLC; Saidly do not contact with the scraper plate arm for taking material near switch 1.
The utility model is decided to be a fixed value with the rotating speed of sprocket wheel is preset before operation, make its motion that remains a constant speed.During operation, sprocket wheel drives chain and rotates, and the induction projection on the scraper plate is along with motion, because the distance between the induction projection equates that each induction projection equated through the time near switch.When problem such as getting stuck, two adjacent induction projections through near the time of switch unequal, after PLC obtained signal, the control motor quit work, and makes machine not fragile.
The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
Claims (3)
1. scraper plate arm for taking material safety system; Comprise the scraper plate arm for taking material; Said scraper plate arm for taking material comprises first sprocket wheel (2), second sprocket wheel (3), two chains (6) at two sprocket wheel two ends and the scraper plate (4) on the chain (6) at cantilever two ends; It is characterized in that: be equipped with an induction projection (5) on the same position of each scraper plate (4), the side of induction projection (5) is provided with one near switch (1), is connected on the PLC near switch (1); Be connected with a motor (7) on said first sprocket wheel (2), motor (7) is connected with PLC.
2. scraper plate arm for taking material safety system according to claim 1 is characterized in that: the distance between the said every scraper plate (4) equates.
3. scraper plate arm for taking material safety system according to claim 1 is characterized in that: saidly do not contact with the scraper plate arm for taking material near switch (1).
