[0002] For multi-split conductors of transmission lines, a large number of spacers need to be installed between spans, and they are heavy. Especially in mountainous areas with harsh environments, forest areas with dense vegetation, and tower spans across rivers, construction workers often need to carry spacers out of the tower and walk. Since there are many spacers installed between spans, construction workers cannot carry all the spacers between one span on the line at one time and often need to make multiple round trips between the spacer installation position and the tower for high-altitude spacer installation operations. Dragging spacers manually at high altitude has a high labor intensity, and during the uphill and downhill processes, it is completely dependent on manual dragging and braking, which poses a great potential safety hazard and high construction risk.

[0034] The drawings are only for illustrative purposes and should not be construed as limitations on this patent; for better illustration of this embodiment, some components in the drawings are omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. Detailed Embodiments

[0035] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0036] As Figures 1 to 10As shown in the figure, this embodiment provides a multi-functional trolley for installing spacer dampers on transmission lines, which includes a frame 1, a tensioning mechanism 2, a lifting mechanism 3, a traveling mechanism 6, and a distance measuring mechanism 7.

[0037] The following is a detailed description of each of the above components.

[0038] The frame 1 is an aluminum alloy welded structure, with high strength and light weight. An independent compartment is designed in the middle of the frame 1 to install electrical control components such as a battery pack 11 and a controller 12.

[0039] The traveling mechanisms 6 are symmetrically arranged on the left and right sides of the frame. Each traveling mechanism includes two traveling wheels 61 distributed front and back, and a traveling drive unit for driving the rotation of the traveling wheels.

[0040] The traveling wheel 61 is mounted on the traveling wheel shaft 60. Specifically: the traveling wheel 61 is formed by an interference fit of a nylon wheel 62 and a steel bushing 63. The steel bushing 63 and the traveling wheel shaft 60 are connected by a flat key 65. The left side of the steel bushing 63 is limited by an axle shoulder, and the right side is limited by a shaft retaining ring 64.

[0041] At the position corresponding to the traveling wheel shaft 60 on the frame 1, there is a sleeve 14. The sleeve 14 is installed on the wall plate of the frame 1 through a pedestal bearing 13. The traveling wheel shaft 60 is inserted into the sleeve 19. At the same time, two transverse holes are provided on the traveling wheel shaft 60 to cooperate with multiple transverse holes arranged on the sleeve 14 and are fixed by D-shaped pins 15 to form a telescopic sleeve structure with adjustable length, which can adjust the distance between the traveling wheels according to different conductor spacings.

[0042] The traveling drive unit includes a reduction motor 81 installed on the wall plate of the frame 1 through a flange. The output shaft of the reduction motor 81 passes through the wall plate hole to install a pinion 82. A large gear 83 is installed on one of the sleeves. The pinion 82 is meshed with the large gear 83; at the same time, transmission wheels are installed on the two sleeves 19 respectively, and a synchronous belt 84 is installed between the two transmission wheels. A protective cover 85 is also designed outside the gear transmission structure and the synchronous belt transmission structure.

[0043] During operation, the pinion 82 drives the large gear 83. The large gear 83 drives the traveling wheel shaft 60 to rotate through the sleeve 19, and then drives the traveling wheel 61 to rotate. At the same time, the two sets of synchronous belt transmissions transmit power to other traveling wheels, and four-wheel drive makes the trolley have better climbing ability and adaptability to conductors.

[0044] The distance measuring mechanism 7 is installed on the frame 1, which can conveniently preset the spacer damper spacing and automatically measure the distance.

[0045] Specifically, the ranging mechanism 7 includes a ranging probe 71 located on one side of one of the large gears 83, the ranging probe 71 is mounted on a ranging probe fixing frame 72, the ranging probe fixing frame 72 is mounted on the wall panel of the frame 1 by screws, and the ranging probe signal line passes through the ranging probe fixing frame through-hole and the reserved hole of the frame wall panel to be connected to the controller 12.

[0046] The sensing end of the distance measuring probe 71 points to the end face of the large gear 83; at the same time, five distance measuring induction magnets 73 are evenly distributed in the circumferential direction corresponding to the end face of the large gear 83 and the position of the distance measuring probe.

[0047] Since the rotation speed of the large gear 83 is coaxially installed with the traveling wheel 61 and has the same rotation speed, the distance measuring induction magnet 73 is counted by the distance measuring probe 71 and the groove bottom diameter of the traveling wheel 61 and converted into the traveling distance through the control system. The preset spacing between the spacers is compared and an alarm is given. The online staff completes the installation of the spacers according to the prompts.

[0048] In order to ensure the driving performance of the spacer bar installation trolley, a tensioning mechanism 2 is designed. The tensioning mechanism 2 includes a tensioning wheel 21 located below the running wheel 61 and corresponding to the running wheel 61. The tensioning wheel 21 is installed on the tensioning control structure, and the tensioning control structure drives the running wheel 21 to approach or move away from the running wheel 61.

[0049] The tension control structure includes two arms 22 symmetrically arranged on the left and right sides, the upper ends of the arms 22 are rotatably connected to the frame 1 through a pin, the lower ends of the arms 22 are respectively connected to T-shaped adjustment frames 23, and the front and rear ends of the T-shaped adjustment frames 23 are respectively provided with tension wheels 21. It also includes a lead screw 24 vertically arranged at the midline of the two arms 22, the lower end of the lead screw 24 is transmission-connected to a stepper motor 25, and the stepper motor 25 is fixed to the frame 1 through a motor mounting frame 26; the lead screw 24 is provided with a nut 27 matched therewith, and a nut fixing frame 271 is fixed to the nut 27, and the nut fixing frame 271 is respectively connected to the middle position of the two arms 22 through a connecting rod 28.

[0050] In order to enhance the stability of the screw rod 24, a screw rod support seat 29 is installed on the wall plate of the frame 1 at the top of the screw rod 24. The screw rod support seat 29 is fixed on a screw rod support seat mounting frame 291, and the screw rod support seat mounting frame 291 is connected to the wall plate of the frame 1 by screws.

[0051] In order to adapt to different wire spacings, the lower half of the support arm 22 is a hollow tube, and the end of the T-shaped adjustment frame 23 is plug-fitted with the sleeve and fixed by a pin to form a telescopic sleeve structure with adjustable length.

[0052] After the running wheel 61 of the multifunctional trolley is hung with the wire 4, the stepping motor 25 is started, the screw rod 24 drives the screw nut 27 to move upward, and the connecting rod 28 pushes the support arm 22, the T-shaped adjustment frame 23, and the four sets of tensioning wheels 21 to a horizontal state and then presses the wire 4 to realize the tensioning function.

[0053] The lifting mechanism 3 is installed on the vehicle frame 1 and is used to lift the spacer dampers.

[0054] Specifically, the lifting mechanism 3 includes a vehicle-mounted winch 31 installed on the upper part of the bottom plate of the vehicle frame 1 and a wire guiding derrick 32 installed on the lower part of the bottom plate. A safety hook 33 is installed at the nylon rope end of the vehicle-mounted winch 31. The safety hook 33 passes through the through hole of the bottom plate and the wire guiding derrick 32 and is connected to the ear hole of the spacer damper hook 34. The spacer damper hook 34 is of a T-shaped structure, and spacer dampers 5 are evenly hung on both sides of the spacer damper hook 34. The operator on the tower uses a remote controller to drive the vehicle-mounted winch 31 to lift the spacer damper 5 to the lower part of the conductor 4, and then removes the spacer dampers 5 one by one and completes the installation.

[0055] The working process of the present utility model is as follows:

[0056] After the operator climbs the tower to the designated position with a small amount of tools and the hook end of the nylon rope of the vehicle-mounted winch 31, the safety hook 33 is installed at a suitable position on the tower. The vehicle-mounted winch 31 is driven by the remote controller of the multi-functional trolley to lift the multi-functional trolley to the tower, placed on the conductor 4, and the tensioning wheel 21 is tightened. The vehicle-mounted winch 31 is started, and the safety hook 33 is lowered. The ground staff installs the spacer damper hook 34 on the nylon rope hook and hangs the spacer damper 5 on the spacer damper hook 34. The operator on the tower starts the vehicle-mounted winch 31 again to lift the spacer damper 5 to the lower part of the conductor. Then, the spacer damper spacing is preset on the control panel, and the trolley traveling mechanism is started. When following the trolley to the first installation position, the distance measuring instrument gives an audible and visual alarm, and the first spacer is stopped and installed. The above steps are repeated to complete the installation of all spacer dampers.
