Abstract
The invention discloses a hydraulic oil cooling device of coal mining machine. The hydraulic oil cooling device comprises six cooling plates which are arranged around (up and dowm, right and left, and front and back) and are welded together, wherein the cooling plate comprises a bottom plate, a joint seat, an end plate, a strip plate and a pressing plate, wherein the end plate, the strip plate and the pressing plate are respectively welded on the bottom plate; the pressing plate is connected with the strip plate at a corner of the strip plate; the end plate is connected with two ends of the strip plate; and the joint seat is welded at a corresponding position opposite to the end plate. Compared with the prior part, the cooling device provided by the invention is embedded in various cooling plates of an oil tank by a serpentine waterway; water in the waterway flows fast; and area of the oil contacting cooled water is increased so as to achieve the purpose of fully cooling at high efficiency; furthermore, various plates are connected with each other through the joint seat on the end plate to form a cooled water circulating loop with water source of a cold water pump station, so that entire oil tank composes the hydraulic oil cooling device by self, thereby removing a traditional cooler, stabilizing systems and saving space.
Description
Technical field
The present invention relates to a kind of coal winning machine hydraulic oil cooling device, particularly relate to the water-cooling apparatus that a kind of coal winning machine fuel tank has self.
Background technique
Can produce heat during the coal-mining machine hydraulic system proper functioning, can cause oil temperature too high and make fluid rotten rapidly for a long time, oil viscosity reduces system effectiveness and reduces simultaneously.Therefore keeping the oil temperature is the necessary condition that guarantees the hydraulic system proper functioning within the specific limits, all cooling unit must be housed generally speaking.
Cooler is the most frequently used temperature control facility at present, and the type of cooling commonly used has, and water-cooled is air-cooled cold with ammonia.Because distinctive profile of coal winning machine and compact space are main with water-cooled mainly.The most frequently used water cooler has copper pipe formula water cooler and plate and fin type water cooler.
Copper pipe formula cooler is installed in copper pipe in the fuel tank, and cooling water flows through in managing, and takes away the heat that produces in the fluid, and the cost of this cooler is low, but heat exchange efficiency is low, and volume is big, and water content consumption is big.Strip-fin oil cooler is about to cooling tube and is with outward and a plurality ofly has radiating fin that good thermal conductive material processes to increase heat diffusion area; But this structure cross section of fluid channel is little; Be prone to stop up, be difficult for cleaning, the booster phenomenon under the unsettled a little situation of pressure, will occur and cause the whole system paralysis; Structure and shape is relatively greatly also relatively heavier in addition, is placed on to take too many space in the coal winning machine and be unfavorable for the stringing wiring.
Summary of the invention
The purpose of this invention is to provide a kind of coal winning machine hydraulic oil cooling device, fully high efficiency and heat radiation can make system stability again, save the space.。
For achieving the above object, the technological scheme that the present invention adopts is:
A kind of coal winning machine hydraulic oil cooling device of the present invention; Six cooling plates that assembling welds together before and after comprising up and down; Cooling plate comprises base plate, connection block, end plate, stripe board and pressing plate, and end plate, stripe board and pressing plate are welded on respectively on the base plate, and pressing plate is attached thereto in the stripe board corner and connects; End plate is connected with the two end part of stripe board, and connection block is welded on the relevant position on end plate opposite.
Owing to compare with existing technology, cooling unit of the present invention is to be embedded in each cooling plate inside of fuel tank by serpentine waterways, and current are very fast in the water channel, and the area of contact of fluid and cooling water increases, and has therefore realized the purpose of abundant high efficiency and heat radiation; In addition, the water source through connection of the connection block on the end plate and ground cold water pumping plant between each plate forms cooling water circulation loop, and whole like this fuel tank self has just constituted hydraulic oil cooling device, has saved traditional cooler, and system stability is saved the space.

Embodiment
The present invention will be described below in conjunction with accompanying drawing and embodiment.
Extremely shown in Figure 11 like Fig. 1; A kind of coal winning machine hydraulic oil cooling device of the present invention; Six cooling plates that assembling welds together before and after comprising up and down, cooling plate comprises base plate 1, connection block 2, end plate 3, stripe board 4 and pressing plate 5, its end plates 3, stripe board 4 and pressing plate 5 are welded on respectively on the base plate 1; Pressing plate 5 is attached thereto in stripe board 4 corners and connects; End plate 3 is connected with the two end part of stripe board 4, and connection block 2 is welded on the relevant position formation serpentine waterways on end plate 3 opposites afterwards, and each number of spare parts and size are confirmed according to the size of the base plate 1 of each cooling plate of fuel tank.
Fuel tank is to be formed by the six cooling plate plate assembly weldings in front and back up and down that have the cool cycles water channel, and the water source through connection block 2 connections and ground cold water pumping plant between each piece plate forms whole cooling water circulation loop.Take over simple and conveniently, solved the problem that a lot of traditional cold radiator coolers take place, temperature control is effective, helps improving the working efficiency of coal winning machine.
Owing to compare with existing technology, cooling unit of the present invention is to be embedded in each cooling plate inside of fuel tank by serpentine waterways, and current are very fast in the water channel, and the area of contact of fluid and cooling water increases, and has therefore realized the purpose of abundant high efficiency and heat radiation; In addition, the water source through 2 connections of the connection block on the end plate 3 and ground cold water pumping plant between each cooling plate forms cooling water circulation loop, and whole like this fuel tank self has just constituted hydraulic oil cooling device, has saved traditional cooler, and system stability is saved the space.
