Abstract
The utility model relates to a cooling device of a tunneling machine hydraulic system. A cooling water source of a machine is connected to a main water box by a water filter through pipelines; the main water box is connected to an accessory water box through the pipelines; cooling water of the accessory water box is pumped by a water pump through the pipelines to enter a three-way ball valve through the pipelines; one way of the three-way ball valve returns to the main water box through the pipelines; another way of the three-way ball valve is ejected through the pipelines; hydraulic oil is connected to a plate-fin heat exchanger installed inside the main water box and connected outwards to return to a hydraulic oil box; and the hydraulic oil inside the plate-fin heat exchanger and water inside the main water box are in sealed isolation arrangement. The ejected cooling water cools a cutting head of the tunneling machine, decreases and controls dust, and effectively cools the hydraulic system. The cooling device can ensure the machine to work normally for two hours when no external water source is supplied.
Description
Technical field
The utility model relates to a kind of novel cooling unit, and device from cooling to the development machine hydraulic system that implement specifically can be provided exactly.
Background technique
The hydraulic system cooling unit of down-hole development machine is welded with copper pipe in water tank mostly at present, and volume is big, and heat diffusion area is little, and cooling effect is bad, and hydraulic system is overheated easily, and is inconvenient to weld and safeguard; Machine has only a water tank, and the water yield is few; When the anhydrous supply of machine, can't realize the interior cycle operation of cooling water.Also useful anti-explosion motor drives the cooling unit of fan, because abominable at subsurface environment, dust is very big, and the hydraulic oil cooling effect is not good, often needs to clean, and safeguards extremely inconvenient.Development machine often need shift the place in the down-hole, and it is not convenient to connect the work of external water source, and under no external water source supply, hydraulic system is overheated easily, influences the proper functioning of the hydraulic element of machine.
Summary of the invention
The purpose of this utility model provides a kind of cooling unit of novel development machine hydraulic system, utilizes the cooling of giving cutterhead and the water source of the dirt that goes out to come the cooling liquid pressing system, all can implement cooling when having or do not have the external water source supply.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cooling unit of development machine hydraulic system, it is characterized in that: the cooling water source of machine is received main water box by water filler through pipeline, main water box is received secondary water tank by pipeline, the cooling water of secondary water tank is extracted out by the road to tee ball valve by water pump by pipeline, tee ball valve has two outlets, and one the road gets back to main water box by the road, and ejection is arrived on another road by the road; Hydraulic oil is received through pipeline and is contained in the plate-fin heat exchanger that two stainless steels in the main water box are made, and picks out and gets back to hydraulic oil container, and hydraulic oil in the plate-fin heat exchanger and the water-stop in the main water box are isolated layout.
The cooling water ejection is implemented cooling to the cutterhead of development machine, and reduces and the control dust, and cooling water is taken away the heat of hydraulic oil when ejection simultaneously, effectively the cooling liquid pressing system; Development machine shifts the place, and cutterhead is not worked, and cooling water does not spray, and when no external water source was supplied, cooling unit can guarantee machine energy proper functioning 2 hours.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Embodiment
Design a master 1, secondary water tank 2, water system is received main water box 1 by a water filler 11 earlier, receives secondary water tank 2 by pipeline again.
For guaranteeing the heat diffusion area of hydraulic oil, the plate-fin heat exchanger 3 that the design and installation stainless steel is made in main water box 1 separates hydraulic oil and cooling water with seal ring 4, installs simply, and it is convenient to safeguard, long service life.
The oil return of hydraulic system is returned hydraulic oil container after receiving plate-fin heat exchanger 3 earlier again.When machine had the external water source supply, water pump 12 drew water in secondary water tank 2, regulated tee ball valve 8, water was sprayed onto on the cutterhead cooling cutterhead, minimizing and control dust.Simultaneously, the heat of hydraulic system transmits feedwater by plate-fin heat exchanger in the main water box 3, by water heat is taken away, and reaches the purpose of cooling liquid pressing system; When development machine is walked the transfer work-yard in the down-hole, by the water spray of tee ball valve 8 cut-outs to cutterhead, water pump 12 extracts the water of secondary water tank and gets back to main water box 1, return the interior circulation heat radiation of secondary water tank 2 again, guarantee the machine hydraulic system in normal oil temperature scope, reach to recycle and reduce the warm purpose of oil.
Concrete technological scheme as shown in Figure 1, the cooling water source of machine is received main water box 1 by water filler 11 through pipeline 5, main water box 1 is received secondary water tank 2 by pipeline 13, the cooling water of secondary water tank 2 extracts by the road 9 out to tee ball valve 8 by pipeline 10 by water pump 12, tee ball valve 8 has two outlets, one the road 6 gets back to main water box 1 by the road, and ejection 7 is arrived by the road in another road; Hydraulic oil is received through pipeline and is contained in the plate-fin heat exchanger 3 that two stainless steels in the main water box 1 are made, and picks out and gets back to hydraulic oil container, the water-stop in hydraulic oil in the plate-fin heat exchanger 3 and the main water box 1 is isolated arrange.
The plate-fin heat exchanger that the design adopts stainless steel to make, increasing area of dissipation than the copper pipe cooler of the routine of machine of the same type improves more than 30%, effectively control oil temperature in hydraulic system, external water source is being arranged for seasonable, oil temperature in hydraulic system remains at optimum working temperature at 70 ± 5 ℃; There is not external water source for seasonable, because the structural design of main water box 1 and secondary water tank 2 is arranged, add the interior cyclic design between two water tanks, not only increased the water yield, strengthened the area of dissipation of water, guarantee that two hours operating temperatures of development machine are no more than 85 ℃, satisfy the needs of hydraulic system, effectively prolong the service life of Hydraulic Elements.
