Description
Technical field
The present invention relates to construction machinery production technical field, especially a kind of power set for pavement milling machine.
Background technology
Pavement milling machine is one of main machine of asphalt pavement conserving construction machinery, is mainly used in the asphalt concrete surface layer removings such as highways and streets and gathers around bag, oil wave, reticulate pattern, rut etc.A high-power engine installed by the power set having a kind of milling width to be greater than the pavement milling machine of 2 meters; This milling machine power set comprise the motor be located in frame, and the Power output of described motor is divided into two-way Power output after described transfer case, and a road Power output is connected with clutch, and described clutch is connected with milling and planing drum by belt transmission; Another road Power output of described transfer case is connected with hydraulic pump, and described hydraulic pump to be walked and the hydraulic motor of auxiliary working apparatus is connected with driving by hydraulic tube; The radiator being provided with fan is equipped with in the side of described motor, and described fan is connected with hydraulic motor.In use there is following deficiency in this milling machine power set:
1, because a powerful motor installed by the power set of pavement milling machine, cost is high; Milling machine is when the slow-speed of revolution, low power " idling " duty, and engine power consumption is large, there is the phenomenon of " low load with strong power "; Engine cooling water and hydraulic oil are by radiator heat-dissipation, and drive the hydraulic motor of the fan of radiator to increase the loss of power;
2, when the milling and planing drum of pavement milling machine works, motor will use 2100 revs/min, 1800 revs/min and 1600 revs/min of three kinds of rotating speeds usually, these three kinds of rotation speed change are large, cause the hydraulic pump matched with it will choose by huge discharge demand, transfer case is also wanted corresponding and is chosen large model, price is corresponding improve also, and the manufacturing cost of pavement milling machine is high;
3, the power arm length of engine output end, during work, road-surface milling machine vibration is large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of milling machine power set, and this milling machine power set can solve the problem that the consumption of existing pavement milling machine engine power is large and manufacturing cost is high.
In order to solve the problem, the technical solution used in the present invention is: this milling machine power set, comprise the clutch be connected with milling and planing drum by belt transmission, be located at the hydraulic pump on transfer case output shaft, described clutch device is on the output shaft of first engine one end, the output shaft of the described first engine other end is provided with the first fan, and closely described first fan place is provided with the first radiator; Described transfer case is contained on the output shaft of second engine one end, and the output shaft of the described second engine other end is provided with the second fan, and closely described second fan place is provided with the second radiator.
In above-mentioned milling machine power set technical scheme, technical scheme can also be more specifically: described first engine and described second engine are respectively the first motor and the second motor, and described first motor and described second motor are respectively by being bolted in described frame.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, first, second motor that milling machine power set adopt two power different drives walking and auxiliary working apparatus and milling and planing drum respectively, when pavement milling machine carries out the work such as place transfer, cleaning, as long as start low power second motor just can satisfy the demand, second radiator is cooled by the second fan be located on the second engine output shaft, make full use of the power of the second motor, avoid the phenomenon occurring " low load with strong power ".When pavement milling machine carries out milling work, first, second motor starts simultaneously, drive walking and auxiliary working apparatus and milling and planing drum respectively, first radiator is cooled by the first fan be located on the first engine output shaft, the power of the first motor is fully used, and reduces use cost;
2, because milling machine power set adopt first, second motor that two power is relatively little, cost is low; Choose match with the second motor hydraulic pump, transfer case model little, price is corresponding reduction also, and the manufacturing cost of pavement milling machine reduces;
3, because transfer case is arranged on the output shaft of the second motor, the cantilever of the first engine output shaft is short, and during work, road-surface milling machine vibration is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the bel-drivenn schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Milling machine power set as shown in Figure 1 and Figure 2 comprise the milling and planing drum 13 being arranged on frame 6 bottom and the hydraulic pump 11 be contained on transfer case 10 output shaft, and hydraulic pump 11 to be walked and the hydraulic motor of auxiliary working apparatus is connected with driving by hydraulic tube.Belt pulley is set with at the power shaft of milling and planing drum 13, belt pulley is connected with belt pulley 3 by belt 12, belt pulley 3 is contained on the output shaft of first engine one end by clutch 2, first, second engine in the present embodiment is respectively the first motor 1 and the second motor 9, first motor 1 and the second motor 9 respectively by being bolted in frame 6; The output shaft of first motor 1 other end is equipped with the first fan 5, and the first radiator 4, first fan 5 be equipped with wind scooper near the first fan 5 place is positioned at wind scooper; First radiator 4 is fixed in frame 6 by installing rack.Transfer case 10 is contained on the output shaft of second motor 9 one end, and the output shaft of second motor 9 other end is equipped with the second fan 8, and the second radiator 7, second fan 7 be equipped with wind scooper near the second fan 8 place is positioned at wind scooper; Second radiator 7 is fixed in frame 6 by installing rack.
Because the first motor 1 of adopting two power different and the second motor 9 drive walking and auxiliary working apparatus and milling and planing drum 13 respectively, when pavement milling machine carries out the work such as place transfer, cleaning, as long as start low power second motor 9 just can satisfy the demand, second radiator 7 is cooled by the second fan 8 be contained on the second motor 9 output shaft, make full use of the power of the second motor 9, avoid the phenomenon occurring " low load with strong power ".When pavement milling machine carries out milling work, first motor 1, second motor 9 starts simultaneously, the respectively walking of driving milling machine and auxiliary working apparatus and milling and planing drum 13, first radiator 4 is cooled by the first fan 5 be contained on the first motor 1 output shaft, the power of the first motor 1 is fully used, and reduces use cost.
