Description

Technical Field

[0001] This utility model relates to the field of climbing device technology, specifically a portable climbing machine. Background Technology

[0002] A search of relevant patent literature has not yet yielded a portable climbing machine with the same structure as this utility model. Climbing equipment is mainly used in tower cranes, wind turbine towers, high-voltage power towers, and high-rise buildings for transporting personnel, materials, equipment for maintenance, and emergency rescue. In the existing technology, patent application number "202110458290.4" entitled "An Integrated Climbing Device and Climbing Structure" uses symmetrically arranged motors in the lower power box for drive. However, the motors are difficult to synchronize, and when one motor fails, it easily jams on the guide rail. This structure's lower drive is prone to insufficient power under heavy loads. The entire device is held in place by a rotating clamping module to run on a single guide rail. When the equipment rises to a certain height, it sways due to wind, causing the guide rail to deform and jam. The clamping device is an openable structure composed of a hinge shaft, clamping wheel, button, and limit block. The swaying can easily cause the opening and closing structure to loosen and the hinge shaft to be damaged, posing a safety hazard in the long term. In addition, in practical applications, to prevent unauthorized personnel from damaging the guide rail, the lower end of the guide rail is usually set 1.6 meters above the ground. Therefore, before the climbing equipment can be moved along the guide rail, the operator must lift the equipment by the handle, open the clamping device, and lock it to hold the equipment firmly on the guide rail. The operation process is time-consuming and laborious. The patent application with patent number "202211027470.8" entitled "Climbing Equipment and Climbing System" uses a single motor drive, and the guide rail body and zero-backlash rack are connected by screws or bolts. This connection is prone to loosening after prolonged vibration. During installation, the entire guide rail is in a bent state. Due to the different structures of the rack and guide rail, the deformation during bending is also different, resulting in inconsistent deformation between the guide rail and the zero-backlash rack. This can easily cause oxidation at the contact points during outdoor use. Furthermore, the side-tooth structure can easily cause injury to people during installation and use. Therefore, it is necessary to design a portable climbing machine that is easy to carry, operate, and is safe and reliable to meet practical needs. Summary of the Invention

[0003] The purpose of this invention is to provide a portable climbing machine that is simple in structure, easy to operate, safe and reliable, and easy to carry.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This portable climbing machine consists of a frame, upper drive unit, lower drive unit, clamping device, guide rail assembly, guide assembly, control device, limit device, pedal assembly, cover, guardrail, power supply, wireless controller, and handle. The upper and lower drive units are located vertically within the frame. Clamping devices are installed at the upper and lower drive units on the frame. Clamping wheels I and II in the clamping devices grip the guide rail. The guide assembly works in conjunction with the frame within the guide rail assembly. The upper drive unit, lower drive unit, control device, limit device, and power supply are connected via transmission lines. The pedal assembly is hinged to the frame. The cover is the outer shell of the frame. The guardrail is a mesh structure and detachably connected to the frame. The wireless controller is wirelessly connected to the control unit. The handle is located at the top of the frame.

[0006] The upper drive device consists of an upper drive motor, an upper reducer, and an upper drive gear. The upper reducer is mounted on the output shaft of the upper drive motor, and two upper drive gears are mounted on the upper reducer.

[0007] The lower drive device consists of a lower drive motor, a lower reducer, and lower drive gears. The lower reducer is mounted on the output shaft of the lower drive motor, and two lower drive gears are mounted on the lower reducer.

[0008] The clamping device consists of a bracket, a shaft, clamping wheel I, and clamping wheel II. Clamping wheel I and clamping wheel II are mounted on the bracket via the shaft. The bracket and the two shafts form an "F" shape. Clamping wheel I is a cylindrical roller, and clamping wheel II is an arc-shaped roller.

[0009] The guide rail component consists of a frame, a guide rail, and a connector. The guide rail is connected to the frame via the connector, and the frame has a ladder structure. The connector has a positioning groove that matches the guide rail.

[0010] The guide rail has two rows of tooth holes A that match the upper drive gear and the lower drive gear; parallel arc-shaped guide rail ribs B are provided on both sides of the guide rail on the same plane.

[0011] The guide component consists of a limiting wheel and a support roller. The limiting wheel is used for axial positioning of the climbing machine on the frame. The climbing machine is supported on the frame by the support roller. The limiting wheel and the support roller are set perpendicular to each other.

[0012] The control device is used to control the operation and stop of the upper drive device, the lower drive device, and the limit device, as well as the clamping and releasing of the drive motor brake.

[0013] The limiting device is a limit switch with two upper and lower limits.

[0014] The pedal device consists of a hinge and a pedal. The pedal is connected to the frame via the hinge and folds vertically toward the frame.

[0015] In use, first, place a section of guide rail on the climbing machine and hold it in place with the clamping device. The upper and lower drive gears mesh with the teeth on the guide rail. Move the climbing machine to the bottom of the power pole, and connect the guide rail on the climbing machine with the guide rail on the pole. Open the footboard, install the guardrail, and the worker should wear operating tools, fasten the safety belt, connect the fall arrestor, stand firmly and hold the handle, and start the switch. The upper and lower drive motors will start simultaneously, and the climbing machine will climb upward. The limit wheels in the guide component will contact the two inner sides of the upper frame of the guide rail component to ensure axial position. The support rollers in the guide component will contact the two planes of the upper frame of the guide rail component to prevent swaying during the climbing process. After reaching the working surface, press the stop button, and the motor brake will engage under the action of the control device. After the work is completed, press the descent button to release the brake, and descend back to the ground in the same way as climbing. After reaching the ground, separate the guide rail connection on the climbing machine from the guide rail on the pole, remove the guardrail, and retract the footboard. In the event of top or bottom overtravel during operation, the limit device activates, cutting off the power to the drive motor via the control device and simultaneously locking the brake. If a motor malfunction occurs during ascent or descent and the brake is locked, the control device releases the brake, allowing the machine to return to the ground under its own weight. When transporting materials, the climbing machine is controlled via a remote control.

[0016] The advantages of this utility model are: Due to its dual-drive design (upper and lower drive devices), with two gears on each drive device, one gear meshes with a toothed hole on the guide rail, thus distributing the driving force. This improves climbing performance and stability while reducing wear on the gears and guide rail teeth, extending service life. Furthermore, if one drive fails, the other drive can continue climbing, improving the reliability of the equipment. The clamping device is designed with an "F"-shaped fixed structure, and the clamping wheels combine cylindrical and arc-shaped rollers, ensuring the stability of the clamping device on the guide rail. The guide rail component is designed to integrate the guide rail with the ladder structure, assembling it into a single unit. This makes installation on the tower more convenient and precise, resulting in smoother climbing. The ladder structure also facilitates installation by personnel. Installation and manual loading / unloading are simple; the guide rail is designed with two rows of toothed holes, ensuring the climbing machine's normal operation even if one row malfunctions; the arc-shaped guide rail ribs on both sides of the guide rail ensure more accurate positioning and smoother operation; the guide components ensure stability during climbing, preventing swaying and protecting the guide rail; the limit device prevents overtravel and derailment; the pedal device is hinged to the frame, facilitating pedal folding and easy carrying; the mesh structure of the guardrail effectively prevents tools and screws from falling from heights, and airflow is discharged through the mesh, reducing airflow resistance during high-altitude construction; the remote control device facilitates the transport of materials; due to its simple structure, ease of use, safety, and reliability, it has great practical and promotional value.
