[0034] Embodiment 2:

[0035] Reference Figure 1-6 The application provides a manual lifting insulating platform device for pole operation, which comprises a platform base mechanism 1, a lead screw 2, an operation platform mechanism 3, a pole holding locking mechanism 4, a lifting control mechanism 6 and a rotating control mechanism 7.

[0036] The platform base mechanism 1 includes a base plate 11 and a worm gear drive assembly mounted below the base plate 11. The screw rod 2 is vertically arranged and extends through the base plate 11. The work platform mechanism 3 installed through the platform base mechanism 1 serves as a standing work platform for the operator, providing a stable foundation for their high-altitude live work. The work platform mechanism 3 includes a platform base plate 31. The front end of the platform base plate 31 is configured as a U-shape, and the screw rod 2 engages with the U-shaped front end of the platform base plate 31. The lower end surface of the front end of the platform base plate 31 is mounted on the base plate 11 via a thrust ball bearing. The specific structure is as follows:

[0037] A longitudinal insulating rod 32 parallel to the platform substrate 31 is provided above the platform substrate 31 . The longitudinal insulating rod 32 is fixedly mounted on the platform substrate 31 via a plurality of insulating support rods 33 .

[0038] A platform support structure 5 is provided below the platform baseplate 31. The platform support structure 5 comprises a support base 51, a connecting sleeve 52, and diagonal insulating rods 53. The connecting sleeve 52 is mounted on the lead screw 2 below the worm gear housing 12, with its upper end fixed to the worm gear housing 12. The support base 51 is mounted on the lower end of the connecting sleeve 52 and fixed to the outer wall of the connecting sleeve 52. Multiple diagonal insulating rods 53 are arranged at an angle, with their upper and lower ends fixed to the lower end surface of the rear end of the platform baseplate 31 and the support base 51, respectively. The provision of the platform support structure 5 helps to avoid stress concentration.

[0039] At the same time, a support rod fixing device 8 is provided on the side of the support base 51 and the worm gear housing 12 away from the platform base plate 31. The support rod fixing device 8 includes a support rod fixing seat 81 and a support rod roller 82. The support rod fixing seat 81 is hinged to the support base 51 or the worm gear housing 12 and can rotate freely left and right. Two support rod rollers 82 are provided and symmetrically mounted on the support rod fixing seat 81. The support rod rollers 82 can contact the utility pole 100 and roll freely up and down. When the entire insulating platform device is used, the support rod fixing seat 81 that can rotate freely left and right can enable the two support rod rollers 82 to simultaneously contact and connect with the utility pole 100, thereby improving the uniformity of the force applied to the support rod rollers 82 and the utility pole 100. At the same time, the support rod rollers 82 that can roll freely up and down can provide support for the worm gear housing 13 or the support base 51 of the platform base mechanism 1, reduce the risk of deformation of the screw rod 2 under the action of external force, and also help improve the stability of the entire platform base plate 31.

[0040] The worm gear transmission assembly under the base plate 11 is engaged with the screw 2. The specific structure is as follows:

[0041] The worm gear transmission assembly includes: a worm wheel, a worm, a worm wheel housing 12 and a worm housing 13. The worm wheel housing 12 and the worm housing 13 are both cylindrical structures. The worm wheel housing 12 is sleeved on the screw 2 and its upper end is fixed to the lower end surface of the base bottom plate 11. A worm wheel inner tube is sleeved on the screw 2 in the worm wheel housing 12. The upper and lower ends of the worm wheel inner tube are connected to the worm wheel housing 12 through bearings. The internal thread of the worm wheel inner tube is consistent with the external thread of the screw 2; the worm housing 13 is installed horizontally on the outside of the worm wheel housing 12 and is interconnected with the inside of the worm wheel housing 12. The worm is installed in the inside of the worm housing 13 through a bearing. The worm wheel is sleeved on the worm wheel inner tube and meshes with the worm. The rotation of the worm can drive the rotation of the worm wheel and the inner tube of the worm wheel, and drive the lifting and lowering movement of the worm gear transmission assembly including the worm wheel, worm, worm wheel housing 12 and worm housing 13 on the screw 2; the worm-worm wheel-screw structure can achieve self-locking at any time during the lifting process and has good stability.

[0042] The lifting control mechanism 6 includes a lifting and reversing ratchet wrench 61, a connecting rod 62, an upper pedal seat 63, and a lower pedal seat 64. A disc handle 14 is mounted on the worm gear input end, and a handle gear 15 is mounted on the disc handle 14. The front end of the lifting and reversing ratchet wrench 61 is mounted on the disc handle 14 and meshes with the handle gear 15. The ends of the connecting rod 62 are axially connected to the end of the lifting and reversing ratchet wrench 61 and the front end of the upper pedal seat 63, respectively. The lower pedal seat 64 is placed on the platform base plate 31 and axially connected to the upper pedal seat 63. A foot spring 65 is provided between the upper pedal seat 63 and the lower pedal seat 64 at the rear of the connecting shaft. A paddle lever 611 is provided on the forward and reverse paddles of the lifting and reversing ratchet wrench 61. The paddle lever 611 can be used to control the forward and reverse paddles to adjust the lifting and reversing ratchet wrench 61 between "forward rotation, reverse idle" and "forward idle, reverse rotation" functions.

[0043] When the lifting and reversing two-way ratchet wrench 61 is in the state of "forward rotation and reverse idling", the operator steps on the pedal upper seat 63 downward, and the pedal upper seat 63 will immediately rotate at the axial connection between the pedal lower seat 64 and the pedal upper seat 63, and then the lifting and reversing two-way ratchet wrench 61 is pulled forward by the connecting rod 62 to rotate forward and drive the worm gear transmission assembly upward on the screw rod 2 through the disc handle 14, the worm, and the worm gear in turn; then, the operator releases the pedal upper seat 63, and the pedal upper seat 63 returns to its original position under the action of the foot spring 65. During this process, the pedal upper seat 63 drives the lifting and reversing two-way ratchet wrench 61 to rotate in the opposite direction, but its reverse rotation is in an idling state and will not affect the disc handle 14, nor will it affect the lifting and lowering of the worm gear transmission assembly. On the contrary, when the lifting and lowering bidirectional ratchet wrench 61 is in "forward idling and reverse rotation" controlled by the shift lever 611, the operator's downward stepping on the pedal upper seat 63 will not affect the lifting and lowering of the worm gear transmission assembly, but the pedal upper seat 63 will drive the worm gear transmission assembly to move downward on the screw rod 2 during the process of returning to its original position under the action of the foot spring 65.

[0044] The worm gear drive assembly controls the elevation of the base plate 11 and the worm gear drive assembly on the screw 2 via the lift control mechanism 6. Adjustment of the lift control mechanism 6, connected to the platform base mechanism 1, allows for the platform base mechanism 1 to be raised and lowered on the screw 2, providing excellent operability. Furthermore, a foot-operated linkage mechanism replaces a rotary handle, allowing workers to operate the platform without bending over, making it convenient and efficient.

[0045] Two pole locking mechanisms 4 are provided and are respectively installed at the upper and lower ends of the screw rod 2. The screw rod 2 is locked with the electric pole 100 through the pole locking mechanism 4. The specific structure is as follows:

[0046] The pole locking mechanism 4 comprises a pole base plate 41, a left connecting plate 42, a right connecting plate 43, a connecting chain 45, a locking adjustment rod 46, a tightening screw 47, a locking sleeve 48, and a locking stop ring 49. The pole base plate 41 is fixed to the upper or lower end of the screw rod 2. The left connecting plate 42 and the right connecting plate 43 are connected to the left and right sides of the pole base plate 41 via connecting chains 45, respectively. One end of the connecting chain 45 is connected to the left or right connecting plate 42, 43, and the other end is hinged to the pole base plate 41 via a U-shaped connector 44. The pole base plate 41, the left connecting plate 42, and the right connecting plate 43 are in close contact with the utility pole 100 and serve as the locking force points.

[0047] The locking adjustment rod 46 is a long cubic rod and is fixedly mounted on the outside of the left connecting plate 42. A center hole that is compatible with the cubic locking adjustment rod 46 is provided at the axis of the tightening screw 47. The locking adjustment rod 46 is passed through the center hole of the tightening screw 47. The locking adjustment rod 46 and the tightening screw 47 are respectively provided with a number of equally spaced locking adjustment holes 1 461 and locking adjustment holes 2 471. The locking adjustment hole 1 461 and the locking adjustment hole 2 471 are fixed by a pin shaft.

[0048] The locking sleeve 48 is mounted on the front side of the tightening screw 47 and fixed to the outside of the right connecting plate 43. The locking stop ring 49 is mounted on the rear side of the tightening screw 47 and is connected to the tightening screw 47 through a thread. A locking adjustment knob 491 is mounted on the tightening screw 47 on the rear side of the locking stop ring 49. The locking adjustment knob 491 is fixed to the locking stop ring 49 via a connecting rod.

[0049] The locking mechanism 4 and the utility pole 100 feature two adjustment methods: First, the locking adjustment rod 46 and the tightening screw 47 are initially adjusted via a pin, enabling coarse adjustment of the locking sleeve 48's position. Second, the locking adjustment knob 491 rotates the locking limit ring 49 on the tightening screw 47, enabling fine adjustment of the locking sleeve 48's position. The screw 2 is locked to the utility pole 100 via the locking mechanism 4, enabling locking with poles 100 of varying diameters, ensuring convenient and versatile pole-mounted mounting of the entire insulating platform.

[0050] The rotation control mechanism 7 is installed on the front end of the platform substrate 31 and controls the relative rotation between the platform substrate 31 and the base bottom plate 11 based on the thrust ball bearing. The specific structure is as follows:

[0051] The rotation control mechanism 7 includes a rotating base plate 71, a gear sleeve 72, a large bevel gear 73, a small bevel gear 74, a large rotating gear 75, a small rotating gear 76, a rotating two-way ratchet wrench 77, and a gear box 78. The rotating base plate 71 is fixed to the platform base plate 31 by bolts. The gear sleeve 72 is mounted on the screw rod 2 above the rotating base plate 71 and its lower end is fixed to the rotating base plate 71. The large bevel gear 73 is mounted on the gear sleeve 72. The gear box 78 is mounted on the rotating base plate 71 outside the large bevel gear 73. The small bevel gear 74, the large rotating gear 75, and the small rotating gear 76 are all fixedly mounted in the gear box 78. The small bevel gear 74 meshes with the large bevel gear 73, the large rotating gear 75 is coaxially fixed with the small bevel gear 74, and the small rotating gear 76 meshes with the large rotating gear 75. The front end of the rotating bidirectional ratchet wrench 77 is mounted on the shaft end face of the small rotating gear 76 by a gearing method. The rotating bidirectional ratchet wrench 77 is provided with forward and reverse paddles for controlling the adjustment of its "forward rotation, reverse idling" and "forward idling, reverse rotation" functions.

[0052] By controlling the forward and reverse paddles provided on the rotating two-way ratchet wrench 77, at a certain moment, the rotation of the rotating two-way ratchet wrench 77 can only control the platform base plate 31 to rotate in one direction, left or right, based on the thrust ball bearing and the base bottom plate 11; after the forward and reverse paddles are adjusted, the rotation of the rotating two-way ratchet wrench 77 can control the platform base plate 31 to rotate in the other direction. The gear set including the large umbrella bevel gear 73, the small umbrella bevel gear 74, the large rotating gear 75, and the small rotating gear 76 is used as the transmission structure of the rotation control mechanism 7, which has smooth movement, saves time and effort, and is convenient for control operation. The adjustment of the rotation control mechanism 7 fixed to the working platform mechanism 3 can realize the rotation control of the working platform mechanism 3 on the platform base mechanism 1, and has good operability.

[0053] The present invention provides a manually liftable insulating platform device for utility pole operations, which has a compact structure, can be easily lifted, rotated, adjusted, and controlled, is easy to operate, and has high operating efficiency; the gear transmission method of the lifting control mechanism 6 and the rotation control mechanism 7 has high transmission efficiency, can achieve self-locking at any time during lifting and rotation, has good stability, and is highly safe.
