CN202864374U - Belt slipping alarm device of coal feeder - Google Patents

Abstract

The utility model provides a belt slipping alarm device of a coal feeder. The belt slipping alarm device of the coal feeder comprises a channel steel (101). A connection rod (107) is fixed on the channel steel (101), a pair of driving wheels (104) is fixed on the rod head portion of the connection rod (107), the driving wheel (104) is connected with a driven wheel (102) through a belt (103), the driven wheel (102) extends out of the outer portion of the coal feeder device, a cam (105) is installed on the driven wheel (102), and a rotating speed measurement device (106) is installed at the stroke position of the cam (105) and connected with a programmable logic controller (PLC) (107). The belt slipping alarm device of the coal feeder can more accurately collect a signal of belt slipping so that a user is reminded of the belt abnormal information in time.

Description

A coal feeder belt slipping alarm device

technical field

The utility model relates to the technical field of coal feeder devices, in particular to a coal feeder belt slip alarm device.

Background technique

The existing device for detecting the coal fed by the coal feeder is to install a baffle switch on the upper part of the coal feeder belt to detect the presence of coal on the belt. Send it to DCS (distributed control system), and make logical judgment in DCS. The logic is generally to judge whether there is coal on the belt of the coal feeder by combining the signal of coal on the belt and the operation signal of the coal feeder. But the defect of this design is: the switch with coal on the belt is driven by the iron plate installed on the upper part of the belt. When there is coal on the belt, it can send a signal, so when the coal feeder belt slips during operation, Both the coal signal on the belt and the operation signal of the coal feeder exist at the same time, resulting in a logical judgment that the coal feeder is still feeding coal, which is not conducive to the operation and operation personnel to find out the abnormality of the coal feeder belt in time.

Utility model content

The utility model provides a coal feeder belt slipping alarm device to more accurately collect belt slipping signals.

In order to achieve the above object, the utility model provides the following technical solutions:

A belt slipping alarm device for a coal feeder, which includes: a channel steel, on which a connecting rod is fixed, and a pair of driving wheels are fixed on the head of the connecting rod, and the driving wheel and the driven wheel are connected by a belt. The driving wheel stretches out of the coal feeder device, a cam is installed on the driven wheel, and a speed measuring device is installed at the stroke of the cam, and the speed measuring device is connected with a PLC (programmable logic controller).

By implementing the above technical scheme, it has the following technical effects: the coal feeder belt slipping alarm device provided by the utility model can more accurately collect the belt slipping signal, and remind the belt of abnormal information in time.

Fig. 1 is a structural schematic diagram of the coal feeder belt slip alarm device provided by the utility model.

Detailed ways

In order to better understand the technical solution of the utility model, the embodiments provided by the utility model will be described in detail below in conjunction with the accompanying drawings.

The embodiment of the utility model provides a coal feeder belt slipping alarm device, as shown in Figure 1, comprising: a channel steel 101, a connecting rod 107 is fixed on the channel steel 101, and the head of the connecting rod 107 is fixed A pair of driving wheels 104, the driving wheel 104 and the driven wheel 102 are connected by a belt 103, the driven wheel 102 stretches out of the coal feeder device, a cam 105 is installed on the driven wheel 102, and a speed measurement is installed at the stroke of the cam 105 A device 106, the rotational speed measuring device 106 is connected with a PLC107.

Use the encoder and the existing PLC in the coal feeder for programming. In order to ensure reliability, the measurement signal is sent to the PLC of the coal feeder, programmed in the PLC, and the input pulse is judged by the pulse monitoring logic block. When the pulse is lower than the fixed value, the belt slips, and the belt slips signal is output. Enter logical judgments to prompt relevant personnel.

The above is a detailed introduction to a coal feeder belt slipping alarm device provided by the embodiment of the utility model. For those skilled in the art, based on the idea of the embodiment of the utility model, both the specific implementation and the scope of application will be familiar. There are changes, and in summary, the content of this specification should not be construed as limiting the utility model.
