[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Embodiment 1

[0041] like Figure 1-14 As shown, this embodiment provides a transmission line tower climbing device 1, which is a split structure, including a guide rail 2 fixedly installed on the transmission line tower 3 along its height direction, a power platform 4 and a bearing platform 5, a generator 12 and other parts, the bearing platform 5 is docked with the power platform 4, and the power platform 4 is used to drive the bearing platform 5 to move up and down on the transmission line tower 3 along the guide rail 2 to transport line maintenance personnel or maintenance equipment. Among them, the generator 12 is placed on the power platform 4, and a gasoline generator can be used to provide a source of electricity for each electrical device in the equipment. When the power platform 4 is in use, it is installed on the guide rail 2, and the power platform 4 is provided with a motor reducer 431, an electric control box 41 and other structures, which can convert the electric energy of the generator 12 into mechanical energy for the equipment to move along the tower guide rail; when the bearing platform 5 is in use, it is docked, installed and fixed with the power platform 4, and assumes the bearing function of the maintenance personnel. When not in use, it can be disassembled from the power platform 4 and transported separately to reduce the transportation weight of a single individual.

[0042] In this embodiment, Figure 3 As shown, the bearing platform 5 is mainly composed of a body 52 and a bearing frame 51, and the body 52 is fixed to a body fixing plate 1 514 and a body fixing plate 2 515 of the bearing frame 51 by bolt connection.

[0043] In this embodiment, Figure 4-5As shown, the compartment 52 is designed with a compartment door 523, which can be rotated to open and close, and maintenance personnel can enter and exit the equipment through the compartment door 523. The compartment 52 includes a frame structure 521 connected as a whole by a profile beam 5211 through a profile connector 5212, and a thin plate structure 522 is sandwiched in the middle of the frame to achieve the closure of the four sides and the top of the compartment. The thin plate structure 522 is preferably an aluminum alloy thin plate, and the plate is processed with weight reduction holes and ventilation holes. The size and number of the holes can be adjusted according to actual needs. The aluminum alloy thin plate is preferably fixed to the profile beam 5211 by bolts and profile nuts.

[0044] In this embodiment, Figure 6-7 As shown, the carrier frame 51 is mainly composed of a carrier frame welding body 511, a handle 14, an eccentric wheel 15, a docking plate 16, a pedal 512 and a weight sensor 513. The carrier frame welding body 511 is preferably an integrated welded structure, on which structures such as a box body fixing plate 1 514, a box body fixing plate 2 515, and an eccentric wheel fixing plate 516 are welded. The docking plate 16, the pedal 512, and the weight sensor 513 are all fixed to the carrier frame welding body 511 by bolt connection. The handle 14 and the eccentric wheel 15 are installed on the eccentric wheel fixing plate 516 through an axial connection. The handle 14 and the eccentric wheel 15 are coaxially installed. The maintenance personnel can rotate the eccentric wheel 15 around its own axis through the handle 14 to adjust the distance between the eccentric wheel 15 and the docking plate 16. The docking installation and disassembly of the bearing platform 5 and the power platform 4 can be realized through the handle 14, the eccentric wheel 15, and the docking plate 16. The pedal 512 can directly contact the foot of the maintenance personnel, and directly support the maintenance personnel. The weight sensor 513 is used to be electrically connected to the electric control box, and can detect the load weight of the pedal 512. When the pedal 512 is overloaded, an alarm can be issued. For example, an alarm can be set to remind the maintenance personnel that the load platform is overloaded, so as to avoid damage to the load platform and reduce the service life of the load platform.

[0045] In this embodiment, Figure 8-11 As shown, the power platform 4 is mainly composed of a main structure 42, a knob pin 18, a rotating frame 13, an electric control box 41, a motor reducer 431, an anti-fall device 8, a driving gear 432, an anti-fall gear 9, a limit wheel 10, a transmission plate 19, and a guide wheel 11. The main structure 42 is an integrated welded structure, and structures such as a docking channel steel 17, a guide wheel mounting seat 421, a knob pin mounting seat 422, and a rotating frame mounting member 423 are welded on both sides thereof. The knob pin 18 is fixed to the knob pin mounting seat 422, and the cylindrical pin at its head can be manually retracted and ejected to achieve the positioning and locking between the power platform 4 and the load-bearing platform 5. The rotating frame 13 is rotatably connected and installed on the rotating frame mounting member 423 through an axis. The rotating frame mounting member 423 is located on one side of the main structure 42. The rotating frame 13 can rotate around its own axis. The unfolded view of the rotating frame 13 is shown in FIG. Fig. 9As shown, when unfolded, a generator 12 can be placed on it; when not in use, the generator 12 is removed from the rotating frame 13, and the rotating frame 13 can be folded (see Fig.11 ) to reduce the overall volume of the main structure 42 for easy transportation. The electric control box 41 is fixed to one side of the transmission plate 19 by bolt connection, and is internally provided with electrical components such as a controller, a filter, a circuit breaker, and a relay to realize the motion control function of the equipment. The motor reducer 431 and the anti-fall device 8 are installed side by side on the same side of the transmission plate 19, and the motor reducer 431 and the driving gear 432, and the anti-fall device 8 and the anti-fall gear 9 are respectively connected together. The driving gear 432 rotates under the drive of the motor reducer 431 and meshes with the first rack 6 on the guide rail 2, serving as the motion execution component 43 of the equipment; the anti-fall gear 9, as a passive rotating component, meshes with the second rack of the guide rail 2, and is the safety protection component 7 of the equipment, and the second rack and the first rack 6 are the same rack structure, and the anti-fall gear 9 and the driving gear 432 are arranged up and down, and both mesh with the rack structure. The fall arrester 8 is equipped with a fall arrester detector, which can monitor the speed of the equipment in real time. When the equipment encounters an unexpected situation and causes a stall and fall, the fall arrester 8 can immediately act to stop the rotation of the fall arrester gear 9, thereby stopping the movement of the equipment and protecting the safety of the equipment. The limiting wheel 10 is mainly used to cooperate with the driving gear 432 and the fall arrester gear 9 to prevent the gap between the driving gear 432, the fall arrester gear 9 and the guide rack from being too large, causing the movement to be unsmooth. The guide wheel 11 is installed on the guide wheel mounting seat 421 and can rotate along its own axis. There are four on one side, a total of eight, and each two are in a group. The circular groove 111 of the guide wheel 11 cooperates with the outer cylindrical surface of the guide cylinder 21, so that the equipment can only move up and down along the direction of the guide rail 2.

[0046] In this embodiment, the transmission plate 19 is preferably a steel plate structure with weight-reducing holes processed thereon, and is fixed to the main structure 42 by bolts around the periphery, and is the main installation and fixing structure for the motor reducer 431, the anti-fall device 8, the driving gear 432, the anti-fall gear 9, and the limiting wheel 10. Among them, there are multiple limiting wheels 10, which are spaced and distributed on one side of the driving gear 432 and the anti-fall gear 9, and the guide rack is located between the gears (driving gear 432 and the anti-fall gear 9) and the limiting wheel 10.

[0047] In this embodiment, Figure 12-14As shown, after the power platform 4 is installed on the guide rail 2, move the bearing platform 5 toward the power platform so that the docking channel steel 17 of the power platform 4 is aligned and inserted into the space between the docking plate 16 of the bearing platform 5 and the eccentric wheel fixing plate 516. After the two platforms reach the predetermined installation position, manually eject the head cylindrical pin of the knob pin 18 on the power platform 4 from the tail end of the knob pin 18 and enter the positioning hole of the bearing platform 5 to complete the docking positioning of the two platforms. After the positioning is completed, rotate the handle 14 to drive the eccentric wheel 15 to rotate, so that the distance between the eccentric wheel 15 and the docking plate 16 is reduced, and the eccentric wheel 15 presses against the docking channel steel 17 of the power platform 4 and self-locks, playing a major role in bearing the force. After the docking is completed, the bearing platform 5 and the power platform 4 are as shown Fig.13 As shown, the tightening partial diagram of the eccentric wheel 15 is as shown in Fig.14 shown.

[0048] It can be seen that the transmission line pole tower climbing equipment provided by this embodiment has a reasonable structural design. Line maintenance personnel can use the equipment to perform pole tower operation and maintenance, which reduces the physical exertion of maintenance personnel climbing the tower, allowing maintenance personnel to retain more physical strength to perform operations on the tower, increasing the high-altitude operation time, improving operation efficiency, and effectively ensuring the safety of maintenance personnel. This embodiment effectively solves the transportation problem from the ground to the top of the pole tower when the transmission line maintenance personnel are working, while reducing the labor intensity of personnel, improving operation efficiency, and having strong practicality.

[0049] In addition, the transmission line pole tower climbing device of this embodiment is transported to the pole tower location and installed on the pole tower rail when in use; when not in use, it can be removed from the pole tower rail and stored indoors, reducing the failure rate and maintenance cost of the equipment. At the same time, this embodiment realizes a split modular design of the equipment, which can effectively reduce the weight of a single unit and facilitate equipment transportation.
