Description

Technical Field

[0001] The invention belongs to the technical field of round rod climbing equipment, and in particular relates to a self-locking self-adaptive lifting work platform. Background Art

[0002] In the early days, operators climbing facilities like utility poles relied on climbing shoes and safety belts. This not only consumed considerable physical effort but was also extremely inconvenient when troubleshooting line faults. However, with technological advancements, more advanced climbing devices have emerged, reducing physical exertion to a certain extent while also providing space for operators to store tools and materials. For example, some pole climbing devices utilize a design similar to a climbing vehicle, with multiple wheels contacting the pole surface and utilizing the rotation of the wheels to achieve climbing. This improves climbing flexibility and can accommodate some tapered poles. However, these devices typically utilize specialized motors to control the tightening and loosening process, which not only increases structural complexity, size, and weight, but also compromises normal operation in the event of a malfunction. Summary of the Invention

[0003] In order to solve the above problems existing in the prior art, this solution provides a self-locking adaptive lifting work platform.

[0004] The technical solution adopted in the present invention is:

[0008] The electric-driven lifting assembly includes a V-shaped drive wheel. Multiple V-shaped drive wheels of the electric-driven lifting assembly can be attached to the outer wall of the cylindrical rod. The V-shaped drive wheel is driven by a drive motor to control the climbing and descending of the mounting support on the cylindrical rod.

[0013] As an alternative or supplement to the above structure: a slide rail assembly is arranged between the electric drive lifting assembly and the mounting support, and the slide rail assembly includes an inclined pressure slider and a linear guide rail that slide with each other, and the linear guide rail is fixed on the mounting support; the inclined pressure slider is fixed on the electric drive lifting assembly.

[0014] As an alternative or supplement to the above structure: the mounting support includes two arc-shaped seats, one end of the two arc-shaped seats is connected by an opening and closing hinge; when the two arc-shaped seats are closed, the ends of the two arc-shaped seats are locked by a closed rotary lock.

DETAILED DESCRIPTION

[0025] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.

[0026] like Figures 1 to 5 As shown, this embodiment designs a self-locking adaptive lifting work platform, including components such as a mounting support, a control box 2, an electric drive lifting assembly 4, and a slide rail assembly 6.

[0027] The mounting support is in the shape of a circular ring; when in use, the mounting support is sleeved on the outside of the cylindrical rod 3; the mounting support includes two arc-shaped seats 1, namely the first arc seat 1a and the second arc seat 1b, which can form a complete circle when the two arc seats 1 are closed, and one end of the two arc seats 1 is connected by an opening and closing hinge 14; when the two arc seats 1 are closed, the ends of the two arc seats 1 are locked by a closed rotary lock 15, and the closed rotary lock 15 can adopt a bolt or a snap structure.

[0028] When installing the support, first unlock the closed rotary locks 15 at both ends of the arc seat 1, so that the first arc seat 1a and the second arc seat 1b can be opened with the opening and closing hinges 14 as the axis, and then folded onto the cylindrical rod 3. After folding, use the closed rotary locks 15 to lock the two ends of the arc seat 1. Similarly, when removing, the operation can be reversed.

[0029] Each of the two arc-shaped seats 1 includes an upper pedal 11, a lower pedal 12, and an oblique push bracket 13. The upper pedal 11 is arranged parallel to and above the lower pedal 12, and the two are fixedly connected by a plurality of oblique push brackets 13. The oblique push brackets 13 can be fixed to the upper and lower pedals 11, 12 by welding or screws. The oblique push brackets 13 are required to be provided between the ends of the upper pedal 11 and the lower pedal 12 to facilitate the hinged connection or locking between the two arc-shaped seats 1.

[0030] The upper pedal 11 may be provided with a plurality of foot switches and a brake switch. The foot switches can be used to conveniently control the rotation direction of the drive motor, while the brake switch can be used to short-circuit and brake the drive motor.

[0031] The electric-driven lifting assembly 4 is slidably arranged on the inner ring side of the mounting support. Three or four electric-driven lifting assemblies 4 can be evenly arranged around the mounting support. The sliding track of the electric-driven lifting assembly 4 is inclined to the radial and axial directions of the mounting support, so that when the mounting support of the electric-driven lifting assembly 4 moves upward, it also synchronously gathers toward the center of the mounting support, thereby holding the cylindrical rod 3 tightly.

[0032] When the number of the electric-drive lifting assemblies 4 is three, two of them are arranged on the first arc seat 1a, and the third electric-drive lifting assembly 4 is arranged on the second arc seat 1b; when the number of the electric-drive lifting assemblies 4 is four, two electric-drive lifting assemblies 4 are respectively arranged on the first arc seat 1a and the second arc seat 1b.

[0033] The electric drive lifting assembly 4 includes components such as a balancing bracket 41, a first rod seat 42, a second rod seat 43, a synchronization rod 44, a sliding sleeve 45, a balancing pressure wheel 46, a V-shaped driving wheel 47, a reducer 48 and a driving motor 49.

[0034] The balancing bracket 41 is square in shape. A balancing pressure wheel 46 is rotatably connected to the upper portion of the balancing bracket 41, and a V-shaped drive wheel 47 is rotatably connected to the lower portion of the balancing bracket 41. A drive motor 49 is mounted on the side of the balancing bracket 41 and drives the V-shaped drive wheel 47 through a reducer 48. When the V-shaped drive wheel 47 is in contact with the cylindrical rod 3, the friction between the V-shaped drive wheel 47 and the cylindrical rod 3 enables the V-shaped drive wheel 47 to roll along the cylindrical rod 3. The roller surface of the V-shaped drive wheel 47 is provided with a V-shaped groove, which makes the diameter of the middle portion of the V-shaped drive wheel 47 smaller than the diameter of its ends. This creates multiple contact points between the V-shaped drive wheel 47 and the cylindrical rod 3, increasing the contact area between the rubber drive wheel and the power pole, thereby improving the friction between the two.

[0035] The balancing pressure wheel 46 is located above the V-shaped driving wheel 47 and can play a stabilizing and guiding role during the entire platform lifting process, thereby reducing the shaking of the platform during the lifting process.

[0036] Furthermore, a first rod seat 42 and a second rod seat 43 are provided on opposite sides of the top of the balancing bracket 41. The second rod seat 43 is fixedly connected to the end of a synchronization rod 44. A sliding sleeve 45 is fixed to the first rod seat 42. The synchronization rod 44 of one balancing bracket 41 is slidably connected to the sliding sleeve 45 of an adjacent balancing bracket 41. When multiple balancing brackets 41 are brought together or apart, the sliding sleeve 45 can slide along the length of the synchronization rod 44, thereby changing the distance between adjacent balancing brackets 41. During the disassembly of the first and second rod seats 42, 43, the sliding sleeve 45 and synchronization rod 44 can be disassembled first to avoid interference with the disassembly process of the first and second rod seats 42, 43. Similarly, during the assembly of the first and second rod seats 42, 43, the sliding sleeve 45 and synchronization rod 44 can be assembled first and then assembled to avoid interference with the assembly process of the first and second rod seats 42, 43.

[0037] The synchronization rod can link the three electric-drive lifting assemblies 4, so that the electric-drive lifting assemblies 4 can move upward or downward synchronously, and at the same time, the electric-drive lifting assemblies 4 can gather or expand around the same center.

[0038] A slide rail assembly 6 is provided between the electric drive lifting assembly 4 and the mounting support. The slide rail assembly 6 comprises an oblique pressure slider 61 and a linear guide 62 that slide in cooperation with each other. The linear guide 62 is fixed to the oblique push bracket 13 of the mounting support, and the linear guide 62 points to the center above the mounting support; the oblique pressure slider 61 is fixed to the balance bracket 41 of the electric drive lifting assembly 4. The weight of the mounting support and its mounted accessories can push the electric drive lifting assembly 4 inward obliquely through the slide rail assembly 6, so that the electric drive lifting assembly 4 can be tightly attached to the cylindrical rod 3. Gravity can be used to achieve self-locking of the platform, preventing the platform from suddenly falling. At the same time, it can also be adaptively matched according to the diameter of the round rod, thereby ensuring the climbing effect on the round rod and reducing the complexity of the structure.

[0039] When the diameter of the cylindrical rod 3 changes, the relative position of the electric-driven lifting assembly 4 and the mounting support can adaptively change, thereby ensuring effective contact between the power wheel and the surface of the cylindrical rod 3. This method of utilizing the gravity of the mounting support to adaptively adjust the position of the electric-driven lifting assembly 4 to ensure effective contact between the electric-driven lifting assembly 4 and the mounting support has lower safety risks, simpler structure and lower cost compared to the method of using an electric drive structure in the prior art.

[0040] In addition, a control box 2 and a battery box 7 are fixed between the upper pedal 11 and the lower pedal 12. The batteries in the battery box 7 can power the control box and each drive motor 49. The control box 2 can control the power on and off and forward and reverse rotation of the drive motor 49 of each electric drive lifting assembly 4. The control box 2 can have a built-in battery to power the drive motor 49. The specific lifting can be controlled by the switch on the control box 2 or the switch connected to the control box 2 via a cable. A charging port can be set on the outer shell of the battery box 7. After the charging port is connected to a power source, it is convenient to charge the battery.

[0041] The above embodiments are merely examples for the purpose of illustrating the present invention clearly and are not intended to limit the embodiments. It is not necessary and impossible to enumerate all embodiments here. Obvious changes or modifications derived therefrom are still within the scope of protection of this technology.
