Description

[0002] When hoisting and constructing large-span towers or extra-high voltage transmission line towers, gin poles are needed to erect the iron towers. The iron towers are disassembled into multiple spliceable erection units, and then each erection unit is lifted above the gin pole in sequence through the gin pole and adjacent erection units are spliced. Finally, the erection of the entire iron tower is completed. Therefore, the gin pole is an important tool for tower erection construction in transmission line projects. Generally, two gin poles are required to complete the erection of the iron tower. The two gin poles are respectively supported on both sides of the erection unit to lift the erection unit up.

The hydraulic pump station 1 includes a frame 11, a driving member 12, a hydraulic pump 13, an oil tank 14, a lifting pole control valve group 15, and a synchronous flow dividing member 16. The driving member 12 and the hydraulic pump 13 are arranged on the lower left side of the frame 11, the oil tank 14 is arranged on the right side of the frame 11, and the lifting pole control valve group 15 and the synchronous flow dividing member 16 are arranged on the upper front side of the frame 11. The driving member 12 can be a gasoline engine or a diesel engine. The driving member 12 is connected to the hydraulic pump 13 and is used to drive the hydraulic pump 13 to operate. The hydraulic pump 13 is respectively connected to the oil tank 14 and the lifting pole control valve group 15 through oil circuits. The lifting pole control valve group 15 is connected to the synchronous flow dividing member 16 through an oil circuit. The synchronous flow dividing member 16 is respectively connected to the first lifting pole 2 and the second lifting pole 3 through oil circuits. The synchronous flow dividing member 16 can be a synchronous flow dividing motor and is used to evenly distribute the hydraulic oil to the first lifting pole 2 and the second lifting pole 3. The lifting pole control valve group 15 is used to control the synchronous operation of the first lifting pole 2 and the second lifting pole 3.

[0025] In the present utility model, by connecting the driving member 12 to the hydraulic pump 13, the driving member 12 drives the hydraulic pump 13 to operate. The hydraulic pump 13 is respectively connected to the oil tank 14 and the lifting pole control valve group 15 through oil circuits. The hydraulic pump 13 outputs the hydraulic oil in the oil tank 14 to the lifting pole control valve group 15. The lifting pole control valve group 15 is also connected to the synchronous flow dividing member 16 through an oil circuit. The synchronous flow dividing member 16 is also respectively connected to the first lifting pole 2 and the second lifting pole 3 through oil circuits. The lifting pole control valve group 15 can control the oil pressure of the hydraulic oil output to the synchronous flow dividing member 16. The synchronous flow dividing member 16 evenly distributes the hydraulic oil output from the lifting pole control valve group 15 to the first lifting pole 2 and the second lifting pole 3, thereby driving the first lifting pole 2 and the second lifting pole 3 to operate. By adjusting the lifting pole control valve group 15, synchronous control of the first lifting pole 2 and the second lifting pole 3 can be achieved, enabling the first lifting pole 2 and the second lifting pole 3 to move synchronously with higher synchronous accuracy and more convenient operation.

[0026] Under normal circumstances, the first lifting pole 2 and the second lifting pole 3 always maintain synchronous operation. However, during the construction process, it is inevitable that due to equipment wear and other reasons, there is a deviation in the synchronization between the first lifting pole 2 and the second lifting pole 3, resulting in different heights of the two lifting poles. At this time, it is necessary to finely adjust a single lifting pole to make the two lifting poles at the same height. In some embodiments, such as Figure 2 andFigure 3 As shown, the hydraulic pump station 1 further includes a first regulating valve 17 and a second regulating valve 18. The first regulating valve 17 and the second regulating valve 18 are arranged at the front part of the frame 11. The first regulating valve 17 and the second regulating valve 18 are located between the boom control valve group 15 and the synchronous flow divider 16. The first regulating valve 17 and the second regulating valve 18 are successively connected in the oil circuit between the boom control valve group 15 and the synchronous flow divider 16.

The first regulating valve 17 is used to realize the switching between the synchronous action state and the individual action state of the first boom 2 and the second boom 3. The second regulating valve 18 is used to realize the switching between the individual action state of the first boom 2 and the individual action state of the second boom 3. By setting the first regulating valve 17 and the second regulating valve 18, the switching between the synchronous action and the individual action of the two booms is realized. When the first boom 2 and the second boom 3 need to act synchronously, the first regulating valve 17 is switched to the synchronous action state. At this time, the boom control valve group 15 is adjusted, and the first boom 2 and the second boom 3 act synchronously. When fine adjustment of a single boom is required, first switch the first regulating valve 17 to the individual working state, then switch the second regulating valve 18 to the individual action state of the first boom 2 or the individual action state of the second boom 3, and then adjust the boom control valve group 15 to finally realize the fine adjustment of the first boom 2 or the second boom 3, so that the two booms are at the same height.

The signal receiver 10 plays a role in receiving and transmitting the control signals.

[0029] In some embodiments, as Figure 2 , Figure 5 and Figure 6 shown, the mast control valve group 15 includes an oil inlet valve block 151 and a working valve block 152.
