Description
Technical field
It is a kind of wheel mounted crane that the utility model relates to, and especially relates to a kind of gearbox cooling system of wheel mounted crane.
Background technique
The gearbox of rough terrain wheeled crane is the important driving mechanism of rough terrain wheeled crane; Because the inner gear of gearbox basically all is the high speed transmission; Have a large amount of heatings in the course of the work; So must solve the cooling problem of gear-box lubricating oil, the lubricant oil in the gearbox is controlled in the rational temperature scope.The gear-box lubricating oil type of cooling of general hoist is the cooling system that is equipped with a special use to gearbox.The rough terrain wheeled crane gearbox cooling system of existing technology is as shown in Figure 1, the shared cover fan drive device of the radiator of gearbox radiator and engine-cooling system.This system connects according to routine, is made up of motor 1, gearbox 2, gear pump 3, safety valve 4, radiator 5, engine blower 6 and engine cooling system heat radiator 7 and pipeline.Its working principle is: motor 1 drives gearbox 2, and by certain reduction speed ratio driving gear pump 3, gear pump 3 is delivered to radiator 5 to the lubricating pump in the gearbox.The radiator 5 of gearbox is placed with the radiator front and back of engine-cooling system 7.When motor 1 running, drive engine blower 6, after the 7 blowing coolings of 6 pairs of engine cooling system heat radiators of engine blower, the hot blast of engine radiator just can carry out air-cooled to the radiator 5 of gearbox, and cooling effect is very poor.Particularly when hoist when carrying out low speed climbing process, the heat of the generation of gearbox is maximum, and this moment, engine speed was low, the lubricant oil in the gearbox can fully not cooled off.
The rough terrain wheeled crane gearbox cooling system of existing technology also has a kind of as shown in Figure 2, and the cooling liquid of gear-box lubricating oil and engine-cooling system is carried out exchange heat, thereby reaches the cooling to gear-box lubricating oil.This system connects according to routine, is made up of motor 1, gearbox 2, gear pump 3, safety valve 4, engine cooling system heat radiator 7, engine blower 6 and gearbox radiator 8 and pipeline.Its working principle is: motor 1 drives gearbox 2, and by certain reduction speed ratio driving gear pump 3, gear pump 3 is delivered to gearbox radiator 8 to the lubricating pump in the gearbox.Gearbox radiator 8 is the radiators that can carry out exchange heat.When motor 1 running, drive engine blower 6; After the 7 blowing coolings of 6 pairs of engine cooling system heat radiators of engine blower; The cooling liquid of engine-cooling system just can enter into the gearbox radiator 8 of gearbox; Carry out hot two exchanges with gear-box lubricating oil, thereby reach the cooling purpose, cooling effect is very poor.Particularly when the coolant temperature of hoist is higher, the cooling effect of the lubricant oil of gearbox will reduce greatly, and the lubricant oil in the gearbox can fully not cooled off yet.Because the temperature of gear-box lubricating oil generally is higher than the temperature of engine coolant far away, adopt this kind type of cooling also will influence the temperature of engine-cooling system simultaneously.Not only the gearbox cooling effect is poor for the cooling system of existing gearbox, also will influence the radiating effect of engine-cooling system.
The model utility content
The utility model technical problem to be solved provides a kind of wheel mounted crane gearbox cooling system of good cooling results.
In order to solve the problems of the technologies described above; The wheel mounted crane gearbox cooling system that the utility model provides; Comprise gearbox, gear pump and gearbox radiator; Described gearbox radiator is provided with independently cooling fan drive device, and gearbox is provided with TTS Transmission Temperature Switch, and TTS Transmission Temperature Switch is electrically connected with the control system of described cooling fan drive device.
Further, described cooling fan drive device is that motor or oil hydraulic motor are connected with fan, and the corresponding cooling with described gearbox radiator of described fan is installed.
Further, the oil outlet of described gearbox radiator is provided with feedback temperature sensor, and described feedback temperature sensor is electrically connected with the alarm signal reponse system.
More than improving technological scheme can implement alone or in combination.
Adopt the wheel mounted crane gearbox cooling system of technique scheme, cooling system is provided with independently cooling fan drive device, and with gearbox in the lubricating oil temperature sensor that is provided be connected; The radiator oil outlet of cooling system is provided with the Temperature Feedback switch.Realize the variation of cooling fan drive device, and cool off the lubricant oil in the gearbox in real time, and whether can feed back the gearbox cooling system in proper working order along with lubricating oil temperature.Solved in the existing technology and overlapped drive unit and utilize engine coolant to carry out heat exchange cooling gear-box lubricating oil, made the problem of its cooling effect difference with engine-cooling system shared.
The beneficial effect of the utility model is; Owing to take above technological scheme; It has following essential characteristics and tangible advantage: 1, the utility model gearbox cooling system is provided with independently cooling fan drive device, directly to gearbox radiator blowing cooling; 2, according to the lubricating oil temperature sensor inspection oil temperature that is provided with in the gearbox, the unlatching of control fan electromotor, thus reach the effect that gear-box lubricating oil is fully cooled off; 3, be provided with feedback temperature sensor, whether the work that can detect the gearbox cooling system is good.
In sum, the utility model is a kind of good cooling results and wheel mounted crane gearbox cooling system simple in structure, reliable performance.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
As shown in Figure 3; Be in transmission connection by motor 1 and gearbox 2 and gear pump 3; Gear pump 3 is through the cooling system loop of pipeline and gearbox 2, safety valve 4 and gearbox radiator 5 formation gearboxes 2, and motor 10 is connected with fan 12, and fan 12 and the 5 corresponding coolings of gearbox radiator are installed; Gearbox 2 is provided with TTS Transmission Temperature Switch 9; TTS Transmission Temperature Switch 9 is electrically connected with the control system of motor 10, and the oil outlet of gearbox radiator 5 is provided with feedback temperature sensor 11, and feedback temperature sensor 11 is electrically connected with the alarm signal reponse system.
As shown in Figure 3; Its working principle is: motor 1 drives gearbox 2; By certain reduction speed ratio driving gear pump 3, gear pump 3 is delivered to gearbox radiator 5 to the lubricating pump in the gearbox 2, and independently fan drive device is that motor 10 drives fan 12 air-cooled gearbox radiators 5.The temperature that detects gearbox 2 when TTS Transmission Temperature Switch 9 surpasses one regularly, and motor 10 will start, and carry out air-cooled to gearbox radiator 5; The temperature that detects gearbox 2 when TTS Transmission Temperature Switch 9 is lower than one regularly, and motor 10 will cut out, and avoids the oil temperature of gearbox 2 to cross low and causes the damage of gearbox 2.The temperature that detects gearbox radiator 5 oil outlets when feedback temperature sensor 11 surpasses one regularly; Represent that the gearbox cooling system breaks down or gearbox cooling system ability is not enough; The alarm signal reponse system will produce alarm signal and feed back to the operator, remind operator's parking checking gearbox cooling system.
