Problems solved by technology

[0002] The trigger device has been widely used in the actuators. The actual position of the field equipment is indicated by triggering the position switch. Sometimes the position of the actuator cannot be triggered in time due to the harsh working environment of the actuator, which affects the normal operation of related equipment. The traditional trigger device is mostly One point, because the trigger part is small, so the ability to adapt to the scene is poor

Embodiment Construction

[0012] Such as figure 1 , 2 , as shown in 3, one A new type of two-way stroke compressor, including: a two-way trigger device and a fixing device. The two-way trigger device can meet the travel requirements of the opening direction and the closing direction. The distance between the trigger surface and the fixing device can be determined according to the actual situation on site. Situation adjustment, the total length of the fixing device can be based on the operation of the equipment, reducing the trigger dead zone, and avoiding the malfunction of the main equipment caused by the logical protection action caused by the switch trigger not in place.

[0013] Weld the fixing device part 1 to the plug plate of the outlet door of the coal mill. When the plug plate is opened, it will drive the compressor to move together. When the compressor touches the limit switch, it will press the switch and the open signal will be transmitted through the signal line. In the DCS control syst...

Abstract

The invention relates to the technical field of triggering devices and particularly relates to a novel bidirectional stroke compressor which is designed for a unit-coal-mill exit plugboard door. The stroke compressor includes a bidirectional triggering device and a fixing device. The bidirectional triggering device is capable of meeting starting demands of an open-direction and closing-direction travel switch. The distance between a triggering face and the fixing device can be adjusted according to the practical conditions of a site. The total length of the fixing device can be set according to device motion conditions so as to reduce triggering dead zones and prevent error motions of a main device, resulted from logic protection motions caused by inappropriate triggering of the switches. The design structure of the triggering device is capable of preventing effectively problems of slight deformation of a plugboard door body caused by thermal expansion and incapability of triggering the travel switch, resulted from effects of coal powder pile-up so that travel-switch triggering is more sensitive.

Description

technical field [0001] The invention relates to the technical field of a trigger device, in particular to a new type of two-way stroke compressor mainly designed for the outlet gate of a coal pulverizer of a unit. . Background technique [0002] The trigger device has been widely used in the actuators. The actual position of the field equipment is indicated by triggering the position switch. Sometimes the position of the actuator cannot be triggered in time due to the harsh working environment of the actuator, which affects the normal operation of related equipment. The traditional trigger device is mostly One point, because the triggering part is small, it has poor adaptability to the scene. [0003] . Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a novel two-way stroke compressor, [0005] The object of the present invention is achieved in the following way: a novel two-way stroke c...
