[0025] like Figure 1-Figure 5 As shown, the adjustable chassis of the dispatching winch includes a shell 1, and an adjustment mechanism 2 is provided on the shell 1;
[0026] The regulating mechanism 2 includes four first brackets 201, an oil tank 203, a multi-way pipe 209 and an oil pump 204. The oil inlet end of the multi-way pipe 209 is installed with a three-way pipe 206, the oil inlet end of the three-way pipe 206 is installed with an electric valve 207, one of the oil outlet ends of the three-way pipe 206 is installed with a flow regulating valve 208, the oil outlet end of the oil pump 204 and the oil inlet end of the oil pump 204 and the oil outlet end of the flow regulating valve 208 are all installed with a second hose 205, the four oil outlet ends of the multi-way pipe 209 are all installed with a first hose 202, and the interior of each first bracket 201 is movably connected with a T-shaped sealing block 211. A flat plate 212 is fixed inside the first bracket 201, a spring 213 is installed at the bottom of each flat plate 212, a second bracket 210 is fixed at the bottom of each T-shaped sealing block 211, the oil outlet end of each first hose 202 is respectively installed with the oil inlet end of each first bracket 201, the oil inlet end of one second hose 205 is installed with the oil outlet end of the oil tank 203, the oil outlet end of the middle second hose 205 is installed with the oil inlet end of the electric valve 207, the oil outlet end of the other second hose 205 is installed with the oil inlet end of the oil tank 203, and the bottom end of each T-shaped sealing block 211 is respectively installed with the oil outlet end of each first hose 202. The bottom ends of the four second brackets 210 and the four first brackets 201 are all on the same horizontal plane. The oil tank 203 is installed at the bottom of the inner wall of the housing 1, the multi-way pipe 209 is installed at the bottom of the inner wall of the housing 1, the oil pump 204 is installed at the bottom of the inner wall of the housing 1, and the electric valve 207, The flow regulating valve 208, the three-way pipe 206 and the three second hoses 205 are all inside the shell 1. The oil outlet ends of the four first hoses 202 are all movable through the bottom of the inner wall of the shell 1. The tops of the four first brackets 201 are all fixed to the bottom of the shell 1. A baffle 4 is installed on the front surface of the shell 1. A plurality of heat dissipation holes 5 are provided on the front surface of the baffle 4 near the edge. A filter plate 6 is installed on the rear surface of the baffle 4. The filter plate 6 is located at the heat dissipation port position of the plurality of heat dissipation holes 5. A limit plate 3 is installed between the outer surfaces of the four first brackets 201, and each first hose 202 is at the top of the limit plate 3.
[0027] The effect achieved is that when the height of the dispatching winch chassis needs to be adjusted, the baffle 4 is first removed, and then a proper amount of hydraulic oil is injected into the oil tank 203 through the oil inlet end of the oil tank 203, and then the oil pump 204, the electric valve 207 and the flow regulating valve 208 are connected to the external controller (PLC controller), and then the baffle 4 is reset to its original position, and then the oil pump 204 and the electric valve 207 are started by the controller. At this time, the started oil pump 204 will, with the cooperation of the two second hoses 205 connected to it and the opened electric valve 207, extract the hydraulic oil from the oil tank 203 and transport it to the inside of the three-way pipe 206, and then transport it to the inside of the multi-way pipe 209, and then divert it to each first hose 202. The hydraulic oil is then transported to the interior of the four first brackets 201. When the hydraulic oil is continuously transported to the interior of the four first brackets 201, the gradually increasing hydraulic oil in each first bracket 201 will cause the corresponding T-shaped sealing block 211 to move vertically. Subsequently, the vertically moving T-shaped sealing block 211 will drive the corresponding second bracket 210 to move. At the same time, the moving second bracket 210 will cooperate with the corresponding flat plate 212 to stretch the corresponding spring 213. When the lower side of each T-shaped sealing block 211 contacts the top of the corresponding flat plate 212, the controller is used to close the oil pump 204 and the electric valve 207. At this time, the bottom of each second bracket 210 moves out of the corresponding The interior of the first bracket 201 realizes the height adjustment of the dispatching winch chassis (the height of the dispatching winch chassis is increased at this time). When the second bracket 210 needs to be reset to the initial position (the height of the dispatching winch chassis is lowered), the flow regulating valve 208 is started by the controller, and the flow rate of the flow regulating valve 208 is set. At this time, each second bracket 210 will slowly reset under the cooperation of the rebound force of the corresponding spring 213 and the started flow regulating valve 208. At the same time, the second bracket 210 that is reset will drive the corresponding T-shaped sealing block 211 to reset, and the T-shaped sealing block 211 that is reset will squeeze the hydraulic oil inside the corresponding first bracket 201 and transport it back to the corresponding first hose 2 02, and then collected and transported back to the inside of the multi-way pipe 209, and then transported to the inside of another second hose 205 with the cooperation of the three-way pipe 206, the closed electric valve 207 and the started flow regulating valve 208, and then transported back to the inside of the oil tank 203. When each second bracket 210 is reset to the initial position, the flow regulating valve 208 can be directly closed by the controller. When the oil pump 204, the electric valve 207 and the flow regulating valve 208 generate heat during operation and spread to the inside of the shell 1, the heat spread inside the shell 1 will directly pass through the inside of the heat dissipation hole 5 and be discharged into the environment. At the same time, under the action of the filter plate 6, various debris and impurities in the environment can be prevented from passing through the heat dissipation hole 5 to the inside of the shell 1.
[0028] Working principle: When the height of the dispatching winch chassis needs to be adjusted, first remove the baffle 4, then inject a proper amount of hydraulic oil into the oil tank 203 through the oil inlet end of the oil tank 203, then connect the oil pump 204, the electric valve 207 and the flow regulating valve 208 to the external controller (PLC controller), then reset the baffle 4 to its original position, and then use the controller to start the oil pump 204 and open the electric valve 207. At this time, the started oil pump 204 will, with the cooperation of the two second hoses 205 connected to it and the opened electric valve 207, extract the hydraulic oil from the oil tank 203 and transport it to the inside of the three-way pipe 206, and then transport it to the inside of the multi-way pipe 209, and then divert it to the inside of each first hose 202. Then it is transported to the inside of the four first brackets 201. When the hydraulic oil is continuously transported to the inside of the four first brackets 201, the gradually increasing hydraulic oil in each first bracket 201 will cause the corresponding T-shaped sealing block 211 to move vertically, and then the vertically moving T-shaped sealing block 211 will drive the corresponding second bracket 210 to move. At the same time, the moving second bracket 210 will cooperate with the corresponding flat plate 212 to stretch the corresponding spring 213. When the lower side of each T-shaped sealing block 211 contacts the top of the corresponding flat plate 212, the controller is used to turn off the oil pump 204 and the electric valve 207. At this time, the bottom of each second bracket 210 moves out of the corresponding first bracket. The interior of the bracket 201 realizes the height adjustment of the dispatching winch chassis (the height of the dispatching winch chassis is increased at this time). When the second bracket 210 needs to be reset to the initial position (the height of the dispatching winch chassis is lowered), the flow regulating valve 208 is started by the controller, and the flow rate of the flow regulating valve 208 is set. At this time, each second bracket 210 will slowly reset under the cooperation of the rebound force of the corresponding spring 213 and the started flow regulating valve 208. At the same time, the second bracket 210 that is reset will drive the corresponding T-shaped sealing block 211 to reset, and the T-shaped sealing block 211 that is reset will squeeze the hydraulic oil inside the corresponding first bracket 201 and transport it back to the corresponding first hose 20 2, and then collected and transported back to the interior of the multi-way pipe 209. Then, with the cooperation of the three-way pipe 206, the closed electric valve 207 and the activated flow control valve 208, it is transported to the interior of another second hose 205, and then transported back to the interior of the oil tank 203. When each second bracket 210 is reset to the initial position, the flow control valve 208 can be directly closed by the controller. When the oil pump 204, the electric valve 207 and the flow control valve 208 generate heat during operation and dissipate into the interior of the housing 1, the heat dissipated in the housing 1 will directly pass through the interior of the heat dissipation hole 5 and be discharged into the environment. At the same time, under the action of the filter plate 6, various debris and impurities in the environment can be prevented from entering the interior of the housing 1 through the heat dissipation hole 5.
[0029] The oil pump 204, electric valve 207 and flow regulating valve 208 in the present invention are all existing technologies, and their working principles are already well-known technologies. The models are selected according to actual use, so the oil pump 204, electric valve 207 and flow regulating valve 208 are not explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
