Embodiment Construction

[0012] figure 1 Represents a square electromagnet housing 1 with two electromagnets 10A, 10B. The two electromagnets are made the same as each other and are installed in a mounting hole 2 respectively. The electromagnet includes a cylindrical coil body 3 and an available coil body 3 Magnetized iron core 4 , an axially movable armature 5 and a switching lever 6 . The switch bar 6 that preferably makes one has a figure 1 The switch end 7 below and an operating end 8 at the top, the switch lever is made into a plurality of steps and is provided with an external thread 11 on the middle section 9, it is preferably made into a fine thread with a very small pitch, the switch lever 6 Use the external thread 11 on the middle section 9 to be screwed into a blind hole on the armature 5. This blind hole is made into multiple steps, and an internal thread 14 is equipped from its upper end surface 13, and its pitch is the same as that of the external thread 11. The pitch matches. Here th...

Abstract

An electromagnet switching device for hydraulic or electrohydraulic directional valves, in particular for use in walking brackets in underground excavation installations, has a controllable, contained in a housing (1), including electric The pivot (5), the coil body (3), the magnetizable iron core (4) and the electromagnet (10A, 10B) of the switch lever (6), the switch lever (6) has a hydraulic valve (33A, 33B) ) connected to the closing body (7) and an operating end (8) for manual operation, wherein the switching stroke of the switching lever (6) acting on the closing body is adjustable, and its features are: the switching lever (6) It is connected with the armature (5) by means of screw connection, and the switch stroke can be adjusted through the relative rotation between the armature (5) and the switch rod (6).

Description

technical field [0001] The invention relates to an electromagnetic switching device for hydraulic or electrohydraulic directional valves, in particular for use in walking brackets in underground excavation equipment, having a controllable, contained in a housing and comprising an armature , a coil body, a magnetizable iron core and an electromagnet for a switch rod, the switch rod has a switch end that can be connected to the closing body of the hydraulic valve and an operating end for hand operation, wherein the switch acting on the closing body The switch stroke of the lever is adjustable. Background technique [0002] DE 3823681 A1 discloses a switching device of this type in which a hydraulic valve, such as a servo valve, is operated by an operating lever which is hinged at one end and acts on the switching end of the switching rod at its free end. In order to adjust the armature, it is designed as an adjusting shaft and connected in a rotationally locked manner with an...
