Problems solved by technology

The existing electro-hydraulic slab gate and the gate body of the gate are only made of one layer of steel plate, which does not meet the technology and requirements for cold protection. When the conventional electro-hydraulic slab gate has no cold-proof device in the case of poor environment, the electric The hydraulic slab gate may have failures such as being stuck and not moving, because its gates are parallel, so there is water on it for a long time, and the gate itself is a single layer without cold-proof facilities. There is a phenomenon of raw freezing, so there is no way to work, which brings certain safety problems

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, a cold-proof electro-hydraulic flat gate includes a gate 1, a hydraulic pusher 2 installed at one end of the gate 1 and an oil cylinder 3 installed on both sides of the gate 1, and the hydraulic pusher 2 is equipped with two-way The lock and the gear pump driven by the motor 4, the gear pump communicates with the two-way lock, and the two-way lock is connected to the oil cylinder 3 through a hydraulic pipeline; the gate 1 is a double-layer fully closed structure, and the outer layer is made of steel plate The inner layer is filled with thermal insulation material, and the outer surface of the gate is provided with a slope. When working, the motor 4 starts to drive the gear pump to transfer the hydraulic oil in the hydraulic pusher 2 to the two-way lock through the pump, and then passes through a hole in the two-way lock and then flows...

Abstract

The invention discloses a cold-proof electro-hydraulic moving bulkhead gate which comprises a flashboard, a hydraulic implementing device and oil cylinders, wherein the hydraulic implementing device is installed at one end of the flashboard, the oil cylinders are installed at two sides of the flashboard. A two-way lock and a gear pump are installed on the hydraulic implementing device, wherein the gear pump is driven by a motor and communicated with the two-way lock, the two-way lock is connected with the oil cylinders through a hydraulic pipeline, the flashboard is in a double-layer fully-enclosed structure, an outer layer of the flashboard is made of a steel plate, and an inner layer of the flashboard is filled with thermal insulation materials. The cold-proof electro-hydraulic moving bulkhead gate has a cold-proof function, can enable water accumulated on the flashboard to flow away rapidly, can not be invalid due to icing of the surface, and therefore products are enabled to be safer and more reliable.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to an electro-hydraulic dynamic flat gate. Background technique [0002] The electro-hydraulic flat gate is widely used in pipelines for controlling the flow of dust materials in building materials, metallurgy, mining and other industries, and is an ideal device for controlling the flow of dust materials. The existing electro-hydraulic slab gate and the gate body of the gate are only made of one layer of steel plate, which does not meet the technology and requirements for cold protection. When the conventional electro-hydraulic slab gate has no cold-proof device in the case of poor environment, the electric The hydraulic slab gate may have failures such as being stuck and not moving, because its gates are parallel, so there is water on it for a long time, and the gate itself is a single layer without cold-proof facilities. There is a phenomenon of raw freezing, so there is no wa...
