Problems solved by technology

However, the housings of the locking lifting devices often do not have the necessary strength for the actually existing operating conditions.
On the one hand, therefore, there are housing solutions of this type for electrohydraulic actuating devices, which are rather complicated to manufacture and, for example, in the case of housings made of cast parts, are not suitable for different shapes of the device. and size, each requires a different tool
On the other hand, housing solutions are prescribed in which several different construction components have to be produced and interconnected and which have significant disadvantages in terms of strength and stability

Abstract

An electrohydraulic actuating device (10), having an electric motor (1) and having a pump (2) driven by said electric motor, for the operation of a hydraulic control cylinder (8) of a hydraulic unit (3), wherein the motor (1) and the hydraulic unit (3) are each accommodated in a housing part (21, 22) of a housing (20), and wherein the housing (20) is equipped, at least in sections, with outwardlypointing cooling fins (4), wherein the housing (20) has a cuboidal or rectangular cross-sectional shape with substantially straight wall sections (23) situated at least on two opposite sides, which wall sections are formed with planar depressions or cutouts (24) which are continuous in the longitudinal direction, and the cooling fins (4) are provided at least partially in the form of removable plate-like cooling modules (5) which, for the insertion and installation thereof, are adapted in terms of shape and depth to the depressions or cutouts (24) of the housing (20).

Description

technical field [0001] The invention relates to an electrohydraulic actuating device according to the preamble of claim 1 , having an electrically driven motor and a hydraulic pump for operating a hydraulic control cylinder of a hydraulic unit. Such electrohydraulic actuating devices are used for regulating motions (Verstellbetrieb) of various devices and installations. In particular, the invention relates to an electrohydraulic actuating device, which is used as a so-called brake lifting device in braking systems and devices for braking, for example, crane systems. The electrohydraulic actuating device has an electric motor and a hydraulic unit coupled to the electric motor. Furthermore, the hydraulic unit is formed by a hydraulically actuated control cylinder which is actuated by a suitable control unit. The hydraulic unit also includes a set of tank components for hydraulic fluid and corresponding channels or lines. The hydraulic unit of the manipulator also includes hyd...
