Abstract
The utility model discloses a hydraulic brake displacement protective device which comprises a hydraulic brake device, a lever arranged on the top of a piston rod of the hydraulic brake device, a brake bar connected to and arranged under the lever, and a displacement sensor installed on the frame at the side close to the top of the piston rod, wherein the displacement sensor is connected with a motor through a controller. The hydraulic brake displacement protective device is simple in structure, and low in cost, senses the moving state of the piston rod on a real time basis, and ensures reliable and safe brake.
Description
Technical field
The utility model relates to a kind of hydraulic brake displacement protecting device.
Background technology
Hydraulic brake device is to drive with power motor common source, is used for medium and small driving.Independent power drives in addition, operating state signal is taken from the auxiliary contact of operation contactless switch more, but during for hydraulic brake oil starvation state, cannot correctly judge whether mechanical device opens band-type brake, exist and control defect, easily cause actuating device locking or hydraulic-braking system motor burning.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic brake displacement protecting device, and state of kinematic motion that can real-time perception piston rod, guarantees to brake reliable and secure.
The purpose of this utility model is to realize like this; a kind of hydraulic brake displacement protecting device; comprise hydraulic brake device; the piston rod top of hydraulic brake device is arranging a lever; the below connection of lever is arranging a brake rod; in the sidepiece frame near piston rod top, a displacement pickup is installed, this displacement pickup is connected with motor by controller.
The utility model is simple in structure, cheap, and state of kinematic motion that can real-time perception piston rod by displacement pickup, guarantees to brake reliable and secure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
A kind of hydraulic brake displacement protecting device; as shown in Figure 1; comprise hydraulic brake device; the piston rod top of hydraulic brake device is arranging a lever 1; the below connection of lever 1 is arranging a brake rod; in the sidepiece frame 3 near piston rod top, a displacement pickup 2 is installed, this displacement pickup 2 is connected with motor by controller.The utility model is simple in structure, cheap, and state of kinematic motion that can real-time perception piston rod, guarantees to brake reliable and secure.
