[0033] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0034] like Figures 1 to 10 As shown, a self-lifting cableway trolley transport system includes a moving device and a transport body 100, the moving device includes a pair of supporting cables 11, the supporting cables 11 are provided with sockets 5 at the loading and unloading locations, and the sockets 5 are externally connected to the main power supply; the transport body 100 includes a pair of trolley frames 3, and the trolley frames 3 are symmetrically installed with moving components that are respectively slidably arranged on the two supporting cables 11 on both sides, and a plug 12 fixed on the trolley frame 3 is provided between the two moving components, and the plug 12 is adapted to the socket 5. The two trolley frames 3 are electrically connected through a wire 10, and a multi-stage hydraulic cylinder 7 is fixed to the bottom end of the trolley frame 3, and a grabbing device 13 is connected to the free end of the multi-stage hydraulic cylinder 7. A driving component for driving the multi-stage hydraulic cylinder 7 to extend and retract is also fixed on the trolley frame 3, and the driving component is electrically connected to the plug 12.

[0035] From the above description, it can be seen that the beneficial effects of the present invention are as follows: by arranging a plug 12 on the trolley frame 3 and arranging a socket 5 compatible with the plug 12 on the supporting cable 11, the plug 12 can be connected to the socket 5 when the trolley frame 3 moves to the loading or unloading position, thereby obtaining electric energy input, and the driving component starts working to drive the multi-stage hydraulic cylinder 7 to extend and retract for loading or unloading. There is no need to manually control the extension and retraction of the multi-stage hydraulic cylinder 7, which greatly reduces the workload of the operator, and the trolley frame 3 can be accurately transported to the corresponding position before power is turned on to drive the multi-stage hydraulic cylinder 7 to work, thereby improving the accuracy of loading or unloading and ensuring smooth operation. At the same time, the operation of the multi-stage hydraulic cylinder 7 does not require human control. Compared with manual control, it avoids the impact caused by human negligence and improves work efficiency.

[0036] Furthermore, the socket 5 is installed on the supporting cable 11 through the guide frame 9. The guide frame 9 includes a transverse sliding rod 901 and a transverse fixed rod 903 arranged parallel to each other. The two ends of the transverse fixed rod 903 are respectively connected to the two supporting cables 11. The two ends of the transverse sliding rod 901 are fixed with sliding sleeves 902. The sliding sleeves 902 are slidably mounted on the supporting cable 11, and a number of brake springs 8 are fixed between the transverse sliding rod 901 and the transverse fixed rod 903.

[0037] From the above description, it can be seen that when the trolley frame 3 is transported by the mobile assembly, there will be a certain inertia. By setting the transverse slide bar 901, the transverse fixed bar 903 and the brake spring 8, the trolley frame 3 as a whole can be braked when the socket 5 and the plug 12 are docked with each other, preventing the trolley frame 3 from exceeding the docking stroke and causing damage to the plug 12 or the socket 5, ensuring that the trolley frame 3 can complete the docking at a certain speed, and then complete the loading or unloading, thereby improving work efficiency.

[0038] Furthermore, the grasping device 13 includes a connecting base 131 and a driving motor 132 and a controller both fixed on the connecting base 131. The driving motor 132 is electrically connected to the controller, and the controller is electrically connected to the plug 12. The connecting base 131 is also rotatably connected to a driving gear 133, a primary driven gear 134 and a secondary driven gear 135 that are meshed and driven in sequence. The driving gear 133 is transmission-connected to the driving motor 132, the primary driven gear 134 and the secondary driven gear 135 are symmetrically arranged, and the sides of the primary driven gear 134 and the secondary driven gear 135 are fixed with swing rods 136 that are symmetrically arranged with each other. The free end of the swing rod 136 is hinged with a clamping rod 137 for clamping, and a power-off self-locking device is provided between the two clamping rods 137, and a hinged rod 138 is hinged between each clamping rod 137 and the connecting base 131, and the two hinged rods 138 are symmetrically arranged.

[0039] As can be seen from the above description, the controller controls the start and stop of the drive motor 132 by turning on the power supply, and drives the rotation of the drive gear 133 by the forward and reverse rotation of the drive motor 132, and then drives the primary driven gear 134 and the secondary driven gear 135 to rotate through the drive gear 133. During the rotation of the primary driven gear 134 and the secondary driven gear 135, the swing rod 136 is driven to swing, and then the clamping rod 137 can be driven to clamp or release under the limiting action of the hinge rod 138, thereby realizing the clamping of the material or the release of the material. Through the setting of the controller, the clamping or release of the clamping rod 137 can be intelligently controlled. Loosen to achieve intelligent control, greatly reducing the burden on staff and improving safety. Operators only need to stack the tower materials in the designated position for easy grabbing by the grabbing device 13. The power-off self-locking device is used to continue to ensure the clamping between the two clamping rods 137 when the controller loses power, to ensure the stability of the tower materials during transportation and prevent them from falling off, thereby improving safety. At the same time, when the controller is powered on, it can also remove the self-locking in time when it is necessary to loosen the clamping rod 137, to ensure the normal progress of the transportation work and further ensure safety.

[0040] Furthermore, the power-off locking device includes a locking pin 14 that is laterally movable and inserted into one of the clamping rods 137, and a socket blind hole 1371 arranged on the other clamping rod 137 and cooperating with the locking pin 14. The locking pin 14 extends out of the clamping rod 137 at one end away from the socket blind hole 1371 and is fixedly connected to the limiting block 141. A first spring 142 that is movably sleeved outside the locking pin 14 is provided between the limiting block 141 and the clamping rod 137. The locking pin 14 extends out of the clamping rod 137 at one end close to the socket blind hole 1371 and is engaged with the socket blind hole 1371. When the plug 12 is disconnected from the socket 5, the locking pin 14 and the socket blind hole 1371 are locked by the controller.

[0041] As can be seen from the above description, when the clamping rod 137 is clamped, the locking pin 14 is inserted into the socket blind hole 1371, and then when the transport body 100 is transported, the socket 5 and the plug 12 are disconnected, and the locking pin 14 is locked with the socket blind hole 1371. At this time, the first spring 142 is compressed to ensure stability and safety during transportation, and when the socket 5 and the plug 12 are re-connected, the locking pin 14 and the socket blind hole 1371 are released, and the first spring 142 is reset. Under the action of the limit block 141, the locking pin 14 is driven to return to the socket blind hole 1371, and then the clamping rod 137 can be opened to complete unloading or loading. The cooperation of the controller and the control of locking or loosening can effectively ensure that the tower material can be stably fixed between the two clamping rods 137 during the whole process of transporting the tower material without electricity. At the same time, no manual control is required during the entire transportation process, which reduces the workload and improves safety. After the controller is powered on, the locking pin 14 can be released in time and reset in time under the action of the first spring 142, ensuring that the clamping rod 137 can be opened in time to load or unload the material, thereby improving the working efficiency of the entire transportation system.

[0042] Furthermore, the locking pin 14 extends out of the clamping rod 137 at one end near the sleeve blind hole 1371 and radially penetrates a receiving cavity 143, in which an electromagnetic plate 144 is fixedly provided, and clamping blocks 146 slidably provided in the receiving cavity 143 are provided on both sides of the electromagnetic plate 144, and a plurality of second springs 145 are fixedly connected between the inner end of the clamping block 146 and the electromagnetic plate 144, and a pair of clamping cavities 1372 adapted to the two clamping blocks 146 are provided on the inner wall of the sleeve blind hole 1371, and an electromagnetic block 1373 is fixedly provided at the inner end of the sleeve blind hole 1371. The electromagnetic plate 144 is electrically connected to the controller. When the controller is powered on, it controls the electromagnetic block 1373 and the electromagnetic plate 144 to generate magnetic force. The clamping block 146 is connected to the electromagnetic plate 144 through magnetic force, and the end of the locking pin 14 close to the socket blind hole 1371 is connected to the electromagnetic block 1373 through magnetic force.

[0043] As can be seen from the above description, in the present invention, the presence or absence of magnetic force of the electromagnetic block 1373 and the electromagnetic plate 144 is controlled by the controller. When the controller loses power, the electromagnetic block 1373 and the electromagnetic plate 144 lose their magnetic force at the same time, thereby causing the electromagnetic block 1373 to lose its magnetic connection with the locking pin 14, and the electromagnetic plate 144 to lose its magnetic connection with the clamping block 146. Then, the clamping block 146 is ejected from the clamping cavity 1372 under the elastic force of the second spring 145, thereby achieving locking. The transport vehicle 100 is in a power-off state throughout the entire transportation process, thereby causing the clamping block 146 to be It can always be in a clamping state with the clamping cavity 1372; when the transport body 100 moves to the loading or unloading position, the plug 12 and the socket 5 are re-docking, the controller is powered on and restarted, and continues to control the electromagnetic block 1373 and the electromagnetic plate 144. When loading or unloading is required, the controller controls the electromagnetic plate 144 to regenerate magnetic force to adsorb the clamping block 146, so that the clamping block 146 loses its locking effect, and at the same time the controller needs to control the electromagnetic block 1373 to lose its magnetic force, that is, lose its adsorption effect on the locking pin 14, so that the locking pin 14 can withdraw from the socket blind hole 1371 under the action of the first spring 142, and then cooperate with the controller to control the clamping rod 137 to loosen, thereby completing the unloading loosening or loading clamping. The control of the controller realizes intelligence and de-manualization, ensuring work efficiency while improving safety.

[0044] Furthermore, a push-pull rod group is provided between the two trolley frames 3 and is located at the lower end of the supporting cable 11. The push-pull rod group includes a first push rod 15 and a second push rod 16. One end of the first push rod 15 is hinged to the trolley frame 3, and the other end is fixed with a plug-in rod 151. At least two sliding rods 152 are evenly fixed on the outer wall of the first push rod 15 along the circumference. The free end of the sliding rod 152 is slidingly connected to the second push rod 16. One end of the second push rod 16 is hinged to the trolley frame 3, and the other end is provided with a plug-in cavity 161 adapted to the plug-in rod 151. A third spring 162 is fixed to the inner end of the plug-in cavity 161, and the third spring 162 is fixedly connected to the plug-in rod 151.

[0045] From the above description, it can be seen that when one of the transport bodies 100 stops, the connecting rod 151 will slide in the connecting cavity 161 under the action of inertia, thereby compressing the third spring 162, and then playing a buffering role, realizing braking buffering between the two transport bodies 100. At the same time, through the setting of the sliding rod 152, the first push rod 15 and the second push rod 16 are prevented from disengaging, ensuring that the distance between the two transport bodies 100 is maintained within a fixed range. If the distance is too large, the wire 10 will be pulled apart, and at the same time, stability during transportation is also guaranteed.

[0046] Furthermore, a friction layer 163 is provided on the inner wall of the plug-in cavity 161 , which is in contact with the plug-in rod 151 .

[0047] It can be seen from the above description that by providing the friction layer 163 , the friction between the connecting rod 151 and the connecting cavity 161 is increased, thereby further improving the braking energy consumption effect and improving the stability during the braking process.

[0048] Furthermore, the mobile component includes a fixed shaft 401, two splints 402 and several rollers 4. The fixed shaft 401 is fixedly connected to the trolley frame 3. The two splints 402 are parallel to each other and are both fixedly connected to the fixed shaft 401. Each roller 4 is movably installed between the two splints 402.

[0049] From the above description, it can be seen that by setting up multiple rollers 4, the contact area between the rollers 4 and the supporting cables 11 is increased, thereby improving the transportation stability of the trolley frame 3. At the same time, the fixed shaft 401 and the two splints 402 are set up to fix the rollers 4, which has good stability and high transportation efficiency, and is suitable for promotion and use.

[0050] Furthermore, the driving assembly includes a pump station valve group 2 and a pump station oil tank 6 fixed on the trolley frame 3, a pump station motor 1 for driving the pump station valve group 2 is installed on the pump station valve group 2, and a multi-stage hydraulic cylinder 7 is transmission-connected to the pump station oil tank 6.

[0051] From the above description, it can be seen that after the plug 12 is docked with the socket 5, the pump station motor 1 is energized to drive the pump station valve group 2, and then the pump station valve group 2 cooperates with the pump station oil tank 6 to control the opening and closing of the oil inlet and oil outlet of the multi-stage hydraulic cylinder 7 to drive the multi-stage hydraulic cylinder 7 to extend and retract, and complete loading or unloading. The drive component can select a suitable drive device according to the specific usage scenario. The hydraulic drive has good stability, small size, light weight, and compact structure. It will automatically self-lock when power is lost during transportation, ensuring that the multi-stage hydraulic cylinder 7 is maintained at a fixed height, preventing the tower material from falling down, and ensuring stability during transportation.

[0052] Furthermore, the multi-stage hydraulic cylinders 7 at the bottom ends of the two trolley frames 3 are arranged on different sides.

[0053] From the above description, it can be seen that when the multi-stage hydraulic cylinders 7 at the bottom ends of the two trolley frames 3 are used for loading or unloading, the multi-stage hydraulic cylinders 7 set on different sides can prevent the tower materials from tipping to one side, thereby effectively improving the stability during the loading or unloading process.

The two trolley frames 3 are electrically connected through a wire 10, and a multi-stage hydraulic cylinder 7 is fixed to the bottom end of the trolley frame 3, and a grabbing device 13 is connected to the free end of the multi-stage hydraulic cylinder 7. A driving component for driving the multi-stage hydraulic cylinder 7 to extend and retract is also fixed on the trolley frame 3, and the driving component is electrically connected to the plug 12.

[0057] Furthermore, the mobile component includes a fixed shaft 401, two splints 402 and several rollers 4. The fixed shaft 401 is fixedly connected to the trolley frame 3. The two splints 402 are parallel to each other and are both fixedly connected to the fixed shaft 401. Each roller 4 is movably installed between the two splints 402.

[0058] Furthermore, the driving assembly includes a pump station valve group 2 and a pump station oil tank 6 fixed on the trolley frame 3, a pump station motor 1 for driving the pump station valve group 2 is installed on the pump station valve group 2, and a multi-stage hydraulic cylinder 7 is transmission-connected to the pump station oil tank 6.

[0059] Furthermore, the multi-stage hydraulic cylinders 7 at the bottom ends of the two trolley frames 3 are arranged on different sides.

[0060] In this embodiment, at the loading location, the plug 12 and the socket 5 are connected to input electric energy, the pump station motor 1 is powered to drive the pump station valve group 2, and then the multi-stage hydraulic cylinder 7 is extended through the pump station valve group 2 in cooperation with the pump station oil tank 6, and the tower material is hoisted by the hook installed at the bottom of the multi-stage hydraulic cylinder 7, and then the multi-stage hydraulic cylinder 7 is continued to be driven to retract, and then the roller 4 is driven by the supporting rope 11 to drive the trolley frame 3 to the unloading location. At the same time, the plug 12 and the socket 5 are also connected at the unloading location, and the pump station motor 1 is powered to drive the pump station valve group 2, and then the multi-stage hydraulic cylinder 7 is extended through the pump station valve group 2 in cooperation with the pump station oil tank 6 to complete the unloading, and finally the multi-stage hydraulic cylinder 7 is driven to retract. During transportation, the multi-stage hydraulic cylinder 7 has no power source and cannot be extended or retracted, thus achieving self-locking.

[0062] In this embodiment, a self-lifting ropeway trolley transportation system is also applied to the transportation of tower materials for power transmission line construction.

[0063] A self-lifting cableway trolley transport system, based on the above embodiment 1, further defines the overall mechanical connection relationship of the grabbing device 13 as follows:
