[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-Figure 4 As shown, the utility model discloses a crawler-type multifunctional tractor power device, comprising:

[0028] Rack 100;

[0029] A power assembly 200, which is arranged inside the frame 100, and includes a power source 201, a hydraulic oil tank 202, a main pump 203, an auxiliary pump 204, a main control valve group 205 and a tailstock valve group 206. The output end of the power source 201 is connected to the main pump 203 and the auxiliary pump 204, and the two ends of the main pump 203 are respectively connected to the hydraulic oil tank 202 and the main control valve; the two ends of the auxiliary pump 204 are respectively connected to the hydraulic oil tank 202 and the tailstock valve group 206; the output ends of the main control valve group 205 and the tailstock valve group 206 are both connected to a quick-connect valve group 207;

[0030] The traveling component 300 includes a base frame 301, a driving wheel 302, a driven wheel 303 and a track 304. The base frame 301 is arranged at the bottom of the frame 100, the driving wheel 302 and the driven wheel 303 are respectively arranged at both ends of the base frame 301, and the track 304 connects the driving wheel 302 and the driven wheel 303; a hydraulic motor 306 is arranged on one side of the driving wheel 302, and the hydraulic motor 306 is connected to the main control valve group 205.

[0031] The frame 100 is used as a support for installing the power assembly 200. The power source 201 in the power assembly 200 drives the main pump 203 and the auxiliary pump 204 to work. The main pump 203 and the auxiliary pump 204 are used to pump the oil in the hydraulic oil tank 202 to the travel assembly 300 and the external components at the bottom to complete the travel of the entire power device and provide power to the motorized capstan. Specifically, the frame 100 at the top and the bottom frame 301 are detachably connected to separate the power assembly 200 and the travel assembly 300 into two integral parts for assembly. The output end of the main pump 203 acts on the main control valve group 205. The main control valve group 205 has six working links, four of which correspond to four groups of drums, that is, it can provide power to the winch systems of four groups of motorized capstans at the same time, and return to the hydraulic oil tank 202 after working on the external equipment; the other two working links correspond to the hydraulic motors 306 of the two groups of tracks 304, driving the hydraulic motors 306 to rotate and drive the driving wheel 302 to rotate, and the driving wheel 302 rotates through the tracks 304 to drive the driven wheel 303 to rotate, so that the entire power device moves, which is suitable for remote mountainous areas and hilly terrains, and is convenient for on-site cableway transportation. The hydraulic oil enters the tail frame valve group 206 after passing through the auxiliary pump 204, and the output of the tail frame valve group 206 acts on the tail frame of the motorized capstan. The main pump 203 and the auxiliary pump 204 cooperate to complete the power output of the four groups of motorized capstans.

[0032] As a preferred solution of the utility model, the base frame 301 and the frame 100 are connected in a pluggable manner, and the base frame 301 and the power assembly 200 are fixed by bolts to achieve rapid disassembly. In addition, the output ends of the main control valve group 205 and the tail frame valve group 206 are both connected to a quick-connect valve group 207, so that the motorized capstan can be directly plugged in and out during use. While ensuring the high efficiency of the system, the pipeline connection is simplified to the greatest extent, which is convenient for later maintenance.

[0033] The utility model adopts a crawler 304 self-propelled structure, and the crawler 304 can be driven by the power center to realize the movement of the entire power device, which is convenient for mountainous operations. The crawler 304 chassis and the power part can also be quickly disassembled, and the mass is reduced after the separation, which is convenient for on-site cableway transportation.

[0034] Furthermore, the power assembly 200 further includes a diesel tank 208 , and the diesel tank 208 is connected to the power source 201 .

[0035] As a preferred solution of the utility model, the power source 201 is a diesel engine, and diesel is added to the diesel tank 208 to provide fuel for the diesel engine. In actual use, the output end of the diesel engine is connected to the main pump 203 and the auxiliary pump 204 to drive the main pump 203 and the auxiliary pump 204 to run.

[0036] Furthermore, the power assembly 200 further includes an air filter 209 and an exhaust muffler 210 . The air filter 209 is connected to the power source 201 , and the exhaust muffler 210 is connected to the air filter 209 .

[0037] Specifically, the diesel engine generates exhaust gas during operation, and the exhaust gas is filtered by the air filter. The air filter generates noise during use, and the exhaust muffler 210 can reduce the noise.

[0038] Furthermore, a hydraulic oil radiator 211 and a heat dissipation water tank 212 are provided on the top of the frame 100 . The hydraulic oil radiator 211 is connected to the hydraulic oil tank 202 , and the heat dissipation water tank 212 is connected to the power source 201 .

[0039] Specifically, during the operation of the entire device, the temperature of the hydraulic oil will increase during use. The hydraulic oil radiator 211 is arranged in the hydraulic circuit to cool down the hydraulic oil when the temperature increases. The heat dissipation water tank 212 is mainly used to cool down the diesel engine and is connected to the water circulation system of the diesel engine.

[0040] Furthermore, the travel component 300 further includes a plurality of support wheels 305 , which are disposed between the driving wheel 302 and the driven wheel 303 , and the support wheels 305 are connected to the base frame 301 .

[0041] Specifically, the support wheel 305 is arranged between the driving wheel 302 and the driven wheel 303, and is used to support the crawler 304. As a preferred solution of the utility model, a plurality of support members 307 are arranged on the side of the chassis 301 close to the frame 100, and the support members 307 abut against the crawler 304. This can avoid the crawler 304 from contacting the chassis 301, and prevent the chassis 301 from being worn during driving.

[0042] Furthermore, a track quick connector 308 is provided between the main control valve group 205 and the hydraulic motor 306 , and the track quick connector 308 is provided on the chassis 301 .

[0043] Specifically, in the present invention, the power assembly 200 at the top and the travel assembly 300 at the bottom are separated structures, and the crawler quick connector 308 arranged on the underframe 301 can realize the quick connection with the power assembly 200. At the same time, the integration of the travel assembly 300 at the bottom can also be ensured.

[0044] Furthermore, a battery 213 is also provided inside the frame 100, and the battery 213 is connected to the power source 201. The battery 213 can ensure the independent use of the entire device. Specifically, the diesel engine can generate electricity during operation, convert mechanical energy into electrical energy, and store the electrical energy through the battery 213 for use in the entire power device. For example, a drive motor is provided inside the hydraulic oil radiator 211, and the electricity can drive the drive motor to rotate, ensuring the normal operation of the hydraulic oil radiator 211.

[0045] Furthermore, pressure sensors are provided on the quick-connect valve group 207 and the tailstock valve group 206 , and the pressure sensors are electrically connected to the main pump 203 and the auxiliary pump 204 .

[0046] Specifically, the pressure value on the entire hydraulic circuit can be detected by the pressure sensor. When the pressure value exceeds the set value, the feedback signal is sent to the main pump 203 and the auxiliary pump 204 to stop working, thereby protecting the entire hydraulic circuit.

[0047] As a preferred solution of the utility model, the main control valve group 205 and the tail frame valve group 206 are both electromagnetic proportional valves, which are used to achieve hydraulic flow regulation and reversing action. To ensure safety when the equipment is working, it is necessary to use a control cable for wired connection operation. When wired connection is used, the walking function of the crawler 304 is forced to be closed.

[0048] In summary, the utility model introduces a crawler-type multifunctional traction machine power device. The power source 201 in the power assembly drives the main pump 203 and the auxiliary pump 204 to work. The main pump 203 and the auxiliary pump 204 are used to pump the oil in the hydraulic oil tank 202 to the bottom travel assembly 300 and the external assembly to complete the travel of the entire power device and provide power for the motorized capstan. The utility model adopts a crawler 304 self-propelled structure. The crawler 304 is driven by the power center to realize the movement of the entire power device, which is convenient for mountain operations. The crawler 304 chassis and the power part can also be quickly disassembled. After the separation, the mass is reduced, which is convenient for on-site cableway transportation.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
