Description

Technical Field

[0001] This utility model relates to the technical field of combined braking equipment, specifically to an electro-hydraulic combined braking device. Background Technology

[0002] An electro-pneumatic system is a comprehensive system that uses electronic / electrical equipment as control devices and pneumatic equipment to drive and provide mechanical energy. The main difference between an electro-pneumatic system and a pneumatic system lies in the control device.

[0003] Application number CN202123070541.6 discloses an electro-hydraulic combined braking device and a blast furnace swing chute. This device employs an electro-hydraulic actuator and a cylinder to achieve parallel electric and pneumatic braking. In the event of an electrical fault, pneumatic braking can be immediately switched without manual switching, making operation simple and quick. This effectively avoids adverse consequences, such as molten iron spillage due to a malfunction in the swing chute's brake, ensuring the safety of tapping iron from the furnace. However, this design has shortcomings: the electro-hydraulic combined braking device is located at one end of the pneumatic motor, lacks a support mechanism, and suffers from poor stability.

[0004] Therefore, we propose an electro-hydraulic combined braking device. Utility Model Content

[0005] The main objective of this invention is to provide an electro-pneumatic combined braking device. Through the design of the support mechanism and support components, the device can be supported, thereby improving the stability of the device at the pneumatic motor end and effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An electro-hydraulic combined braking device includes a fixed base, a support frame, a brake wheel, an electro-hydraulic actuator, and a first cylinder. The brake wheel is mounted on the upper surface of the fixed base. A support frame for mounting the electro-hydraulic actuator and the first cylinder is fixedly connected to the upper part of one end of the fixed base. The fixed base is assembled on the top of a support mechanism. The support mechanism includes a support plate, a support base, an electric cylinder, a piston rod, and a first bolt. The support base is located below the support plate. The support plate is connected to the support base through the piston rod. A limiting groove for mounting the fixed base is provided on the upper surface of the support plate. A protrusion is provided on the lower surface of the support plate near the support frame. A support assembly for supporting the support frame is provided on the upper surface of the support plate at the protrusion end.

[0008] The support assembly includes a threaded rod, a push rod, a push plate, a movable plate, a turntable, a knob, and a second bolt. The upper end face of the support plate at one end of the protrusion is provided with an embedding groove that matches the push plate, and the protrusion is provided with an installation cavity.

[0009] By adopting the above technical solution, the support mechanism is placed below the device, the fixed seat is located in the limiting groove, and the support component at one end of the upper surface of the support plate is located below the support frame. The fixed seat is fixedly connected to the end of the support plate away from the support component by the first bolt. Turning the knob at the bottom of the protrusion causes the turntable to rotate, and the turntable causes the threaded rod to rotate. Through the threaded engagement between the threaded rod and the movable plate, the movable plate can push the push plate upward through the top rod until the rubber pad on the upper surface of the push plate contacts the lower surface of the support frame, thereby achieving the purpose of supporting the support frame and improving the stability of the device. At the same time, the upper structure has the advantage of simple operation.

[0010] Specifically, the threaded rod and the movable plate are both located inside the mounting cavity. The top end of the threaded rod is rotatably connected to the inner wall of the top end of the mounting cavity, and the bottom end of the threaded rod passes through the inner wall of the bottom end of the mounting cavity and is fixedly connected to one side of the turntable.

[0011] Specifically, a knob is fixedly connected at the center of the end of the turntable away from the threaded rod, and the turntable is fixedly connected to the bottom of the protrusion by a second bolt.

[0012] Specifically, the movable plate is fitted onto the threaded rod and threadedly engaged with it, and a top rod is vertically inserted into the upper end face of the movable plate.

[0013] Specifically, multiple push rods are arranged in parallel, and the top end of each push rod passes through the inner wall of the mounting cavity and is vertically inserted into the lower end face of the push plate. A rubber pad is fixedly glued to the upper end face of the push plate.

[0014] Specifically, multiple sets of electric cylinders are fixedly connected to the inner wall of the bottom end of the support base, and a piston rod is connected to the top of the electric cylinder.

[0015] The beneficial effects of this utility model are as follows: The electro-pneumatic combined braking device described in this utility model, through the design of the support mechanism and support components, can achieve the purpose of supporting the device, thereby improving the stability of the device at the pneumatic motor end. The support mechanism is placed below the device, the fixed seat is located in the limiting groove, and the support component at one end of the upper surface of the support plate is located below the support frame. The fixed seat is fixedly connected to the end of the support plate away from the support component by the first bolt. Turning the knob located at the bottom of the protrusion causes the knob to drive the turntable to rotate, and the turntable drives the threaded rod to rotate. Through the threaded engagement between the threaded rod and the movable plate, the movable plate can push the push plate upward through the top rod until the rubber pad on the upper surface of the push plate contacts the lower end surface of the support frame, thereby achieving the purpose of supporting the support frame and improving the stability of the device. At the same time, the upper structure has the advantage of simple operation. Attached Figure Description
