[0002] The roof and concrete walls of hydropower station equipment rooms require frequent maintenance. Hoisting operations also require the installation of a series of auxiliary devices, including lifting points, which are crucial for the daily operation and maintenance of hydropower stations. Therefore, manual installation work at height carries significant risks, including risks of falls and equipment falling.
[0003] At present, in the operation and maintenance process of hydropower stations, most tools or vehicles such as erection and dismantling scaffolding or quick-installation scaffolding, elevators, etc. are used to transport tools to high places.

However, for some narrow areas and the interiors of small rooms, scaffolding and elevators cannot perform the required functions. In addition, the construction period of erection and dismantling scaffolding or quick-installation scaffolding is long and difficult, and the risk of high-altitude operations is high, making it difficult to meet construction requirements. Therefore, a telescopic rod is proposed. This device can not only transport tools to high places, but also rotate at the bottom to cover a larger area. The number of times workers need to move the device during operations is reduced, which improves work efficiency. It also improves operational accuracy and reduces the risk of accidents.

Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.
[0028] Furthermore, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0029] Example 1
[0030] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, provides a telescopic rod that can adjust the angle so that the device transportation tool or equipment can reach a wider operating area, and at the same time can be positioned and operated more accurately, adapt to different working environments, and increase the coverage range.
[0031] Specifically, the telescopic mechanism 100 includes a rotating component 101, a supporting component 102 is provided on the side of the rotating component 101, a limiting component 103 is provided on the top of the supporting component 102, the limiting component 103 is used to limit the position of the supporting component 102, a telescopic component 104 is provided on the top of the limiting component 103, and the telescopic component 104 is used for the extension and retraction of this device. Four universal wheels 105 are symmetrically connected to the bottom of the rotating component 101, and a pushing frame 106 is fixedly connected to one side of the surface of the rotating component 101.
[0032] Furthermore, the rotating assembly 101 includes a support platform 101a, and the rotating assembly 101 is located at the center of the surface of the support platform 101a. A fixed base 101b is fixedly connected to the middle of the surface of the support platform 101a, and a first motor 101c is fixedly connected to the side of the fixed base 101b close to the pushing frame 106. The output shaft end of the first motor 101c is fixedly connected to a worm 101d, and the worm 101d is rotatably connected to the inside of the fixed base 101b. A worm gear 101e is meshed and connected above the worm 101d, and the worm gear 101e is in a vertical relationship with the support platform 101a.
[0033] Preferably, both ends of the worm 101d are rotatably connected to the inner side of the fixed seat 101b, and both sides of the worm wheel 101e are rotatably connected to the rotating seat 101f. The rotating seat 101f is perpendicular to the supporting platform 101a. The top surface of the rotating seat 101f is fixedly connected to the horizontal base 101g, and the center of the surface of the base 101g is fixedly connected to the outer sleeve 101h.
[0034] The staff starts the first motor 101c, and then drives the worm 101d to rotate through the first motor 101c. The rotation of the worm 101d synchronously drives the worm wheel 101e to rotate, thereby causing the rotating base 101f fixedly connected to the worm wheel 101e to rotate. All structures on the top surface of the rotating base 101f also rotate synchronously with the rotation of the worm 101d, so that the structure on the surface of the rotating base 101f can expand its working range, cover areas that were originally inaccessible, improve the comprehensiveness of the operation, and at the same time reduce the movement of the device and improve work efficiency.
[0035] Example 2
[0036] Reference Figure 3 and Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment can significantly improve the overall stability of the telescopic rod by supporting the outer sleeve when working at high altitude or when precise operation is required, preventing the device from tipping over while also improving the accuracy of the operation.
[0037] Specifically, the support assembly 102 includes a slider 102a, which is slidably connected to a slide groove provided on the surface of the support platform 101a. A support spring 102b is fixedly connected to the side of the slider 102a away from the support assembly 102. The end of the support spring 102b away from the slider 102a is fixed to the inner side of the slide groove provided on the surface of the support platform 101a, and the slider 102a is supported by the support spring 102b.
[0038] A vertical sliding rod 102c is fixedly connected to the center of the surface of the slider 102a, a connecting block 102d is fixedly connected to the top of the sliding rod 102c, a vertical notched sliding sleeve 102e is sleeved on the top of the sliding rod 102c, the connecting block 102d slides together with the sliding rod 102c on the side of the notched sliding sleeve 102e, and a rotating shaft 102h is fixedly connected to the end of the notched sliding sleeve 102e away from the sliding rod 102c, and the rotating shaft 102h is rotatably connected to the side of the outer sleeve 101h close to the slider 102a.
[0039] Furthermore, the limiting assembly 103 includes a ratchet 103a, which is symmetrically fixedly connected to both sides of the rotating shaft 102h. A fixed block 103b is fixedly connected to one side of the outer sleeve 101h close to the rotating shaft 102h. A slot 103c is provided at the center of the top surface of the fixed block 103b. Ratchets 103d are symmetrically rotatably connected on both sides of the fixed block 103b, and the pawls 103d cooperate with the ratchet 103a.
[0040] Preferably, a connecting rod 103e is fixedly connected to the top of the surface of the pawl 103d, and a clamping block 103f is rotatably connected to the center of one side of the connecting rod 103e close to the card slot 103c. The clamping block 103f can be clamped into the card slot 103c for fixation. A recovery spring 103g is fixedly connected to the side of the fixing block 103b. One end of the recovery spring 103g close to the connecting rod 103e is fixedly connected to the surface of the pawl 103d. The recovery spring 103g is used to reset the pawl 103d.
[0041] The top of the notched sleeve 102e is rotatably connected to the bottom of the fixed block 103b, so that the rotation of the notched sleeve 102e is not affected by the fixed block 103b. The pawl 103d is clamped on the surface of the ratchet 103a. When the ratchet 103a rotates counterclockwise, the ratchet 103a can be locked by the pawl 103d, and the clamping block 103f can be clamped inside the clamping slot 103c.
[0042] When the support spring 102b is not subjected to external force, the slider 102 is in the sliding groove inside the support platform 101a close to one end of the fixed seat 101b. When the rotating seat 101f is tilted, the slider 102a slides in the sliding groove inside the support platform 101a, and the support spring 102b is squeezed and shortened. At this time, the slide bar 102c slides upward inside the notched sliding sleeve 102e along with the connecting block 102d, and the rotating shaft 102h rotates counterclockwise. The notched sliding sleeve 102e and the slide bar 102c also rotate counterclockwise around the rotating shaft 102h. Since the ratchet 103a is fixed on the rotating shaft 102h, the ratchet 103a also rotates clockwise, synchronously driving the pawl 103d to slide on the outer periphery of the ratchet 103a. When the rotating seat 101f stops rotating, the slide bar 102 c slides to a certain position in the slide groove inside the support platform 101a, and the sliding rod 102c inside the notched sleeve 102e is also in a stationary state. After the ratchet 103a rotates to a fixed angle, it is clamped and fixed by the pawl 103d, thereby fixing the angle between the notched sleeve 102e and the outer sleeve 101h. At this time, the device is fixed and the entire device is in a stable state. When it is necessary to reset the rotating seat 101f, the staff manually toggles the connecting rod 103e, and the pawl 103d rotates on both sides of the fixed block 1030b until the block 103f is clamped into the slot 103c. At this time, the pawl 103d no longer locks the ratchet 103a, and then restarts the first motor 101c to drive the worm gear 101e to reverse, thereby moving the rotating seat 101f to a horizontal state.
[0043] Example 3
[0044] Reference Figure 1 and Figure 5 , which is the third embodiment of the present utility model. Different from the previous embodiment, in this embodiment, the storage basket can be raised to a high place by rotating the second motor, thereby realizing the delivery of the equipment to a high place. At the same time, the pushing frame and the universal wheel make the movement of the device more convenient.
[0045] Specifically, the telescopic assembly 104 includes a second motor 104a, the output shaft end of the second motor 104a is fixedly connected to a screw 104b, the outer periphery of the screw 104b is rotatably connected to an inner sleeve 104c, the inner sleeve 104c rotates in conjunction with the screw 104d, and the top of the inner sleeve 104c is rotatably connected to a storage frame 104d. When the inner sleeve 104c is at an acute angle relative to the support platform 101a, the storage basket 104d can always be parallel to the support platform 101a, ensuring smooth transportation of the equipment inside the storage basket 104d.
[0046] Furthermore, the second motor 104a is fixedly connected to the inner center of the base 101g, and the inner sleeve 104c is slidably connected to the inner part of the outer sleeve 101h and is caused to slide up and down in the outer sleeve 101h through the slide bar groove.
[0047] Preferably, four universal wheels 105 are symmetrically fixedly connected to the bottom surface of the support platform 101a, and a pushing frame 106 is fixedly connected to the side of the support platform 101a surface away from the first motor 101c. By pulling the pushing frame 106 and rotating the universal wheels 105, the movement of the device can be facilitated, thereby improving work efficiency.
[0048] The staff starts the second motor 104a, and the second motor 104a drives the screw 104b to rotate. The screw 104b is threadedly engaged with the inner sleeve 104c and rotates, so that the inner sleeve 104c rotates upward inside the outer sleeve 101h, and synchronously drives the storage basket 104d located on the top of the inner sleeve 104c to move upward. Since the storage basket 104d and the inner sleeve 104c are rotationally connected, when the outer sleeve 101h rotates relative to the support platform 101a, the storage basket 104d can always be parallel to the support platform 101a. The four universal wheels 105 fixedly connected to the bottom of the support platform 101a and the pushing frame 106 on the side of the support platform 101a are used in conjunction with each other. The staff can manually push the pushing frame 106 to rotate the universal wheels 105, which can move this device more conveniently.
