Description

Technical Field

[0001] This utility model relates to the field of telescopic pole technology, and in particular to a telescopic pole device for a high-altitude operating platform. Background Technology

[0002] In the fields of industrial and civil buildings, staircases are not only a key component for vertical transportation, but also vital lifelines for ensuring the safe evacuation of personnel. The construction of stairwells involves multiple processes, including masonry, decoration, and the installation of various equipment. These processes often require working at heights, which introduces certain operational risks.

[0003] For this type of high-altitude work, traditional work equipment such as aerial work platforms and modular operating platforms are often difficult to use smoothly in such scenarios due to limitations imposed by the narrow stairwells and complex spatial layouts. Currently, in the construction of stair-related processes, the industry often uses simple steel pipe scaffolding to erect temporary operating platforms. However, the erection and dismantling of simple steel pipe scaffolding requires a significant amount of time, severely impacting the overall construction schedule. Furthermore, the erection and dismantling operations require substantial manpower, leading to a significant increase in labor costs. In addition, the scaffolding itself occupies a large area, further exacerbating the problem of limited construction space in stairwells. Moreover, the stability of temporary scaffolding is relatively poor, and the installation of safety protection facilities presents numerous difficulties, posing significant safety hazards to workers at height. Therefore, this utility model proposes a telescopic rod device for high-altitude operating platforms. Utility Model Content

[0004] The purpose of this utility model is to address the problems in the background technology that traditional climbing equipment cannot be used due to space limitations in high-altitude operations during stairwell construction, and that simple steel pipe scaffolding has problems such as long erection and dismantling time, high labor costs, large footprint, poor stability, and difficulty in safety protection. The present invention proposes a telescopic pole device for high-altitude operating platforms.

[0005] The technical solution of this utility model is as follows: A telescopic boom device for an aerial work platform includes a support base, a telescopic boom bottom section fixedly connected to the top of the support base, a plurality of telescopic boom intermediate sections sequentially sleeved in the telescopic boom bottom section, a telescopic boom top section located at the center of the telescopic boom bottom section, the top of the telescopic boom top section being fixedly connected to the aerial work platform, and a plurality of equidistant safety insertion holes respectively provided on the telescopic boom bottom section, telescopic boom intermediate sections, and telescopic boom top section; and a plurality of positioning components installed in the safety insertion holes to prevent rotation of the telescopic boom bottom section and telescopic boom intermediate sections.

[0006] Optionally, the inner walls of the bottom section and the middle section of the telescopic rod are respectively fixedly connected with two sets of symmetrically arranged support arc plates.

[0007] Optionally, multiple sets of adjusting arc plates are fixedly connected to the outer walls of the middle section and the top section of the telescopic rod, with two sets of symmetrically arranged adjusting arc plates at the same height.

[0008] Optionally, the lengths of both the supporting arc plate and the adjusting arc plate are less than a quarter circle.

[0009] Optionally, a limit baffle is fixedly connected to the bottom of the adjusting arc plate.

[0010] Optionally, the positioning component includes a safety pin inserted into the safety socket. The safety pin is L-shaped, with a threaded rod threaded to one end of the safety pin and a rotating rod fixedly connected to the end of the threaded rod away from the safety pin.

[0011] Optionally, the top of the telescopic rod is closed, with a connection hole for connecting to the aerial work platform via fasteners.

[0012] In summary, this application includes at least one of the following beneficial technical effects: This utility model, through the cooperation of the supporting arc plate and the adjusting arc plate and the positioning function of the limiting baffle, can quickly rotate and adjust the middle section and the top section of the telescopic rod to achieve length adjustment, and can accurately adapt to the height difference of stairs, which greatly saves construction time and labor costs compared with traditional scaffolding erection and dismantling. Further, by adjusting the maximum contact area between the adjustable arc plate and the supporting arc plate to form a stable support, and with the double locking of the safety socket and positioning component, the relative rotation of each section of the telescopic rod is effectively prevented, the stability of the device is improved, and the problem of difficult safety protection of traditional temporary platforms is solved. In summary, this utility model enables convenient and efficient operation in the narrow space of stairwells, while saving construction time and labor costs, reducing site occupation, and improving operational stability and safety.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0020] like Figure 1 As shown, the present invention proposes a telescopic boom device for an aerial work platform, including a support base 1, which ensures the overall stability of the device. A telescopic boom bottom section 2 is fixedly connected to the top of the support base 1. Two sets of telescopic boom intermediate sections 3 are sequentially fitted into the bottom section 2. The extension length of the telescopic boom intermediate sections 3 can be adjusted vertically, thereby adjusting the overall length of the device.

[0021] Multiple sets of equidistant safety holes 7 are provided on the bottom section 2, the middle section 3, and the top section 4 of the telescopic pole. The safety holes 7 facilitate the insertion of a bolt for locking after the length of the telescopic pole device is determined, preventing relative rotation of the bottom section 2, the middle section 3, and the top section 4.

[0022] For further details, please refer to Figures 1 to 4 The aforementioned telescopic pole device also includes a top telescopic pole section 4 located at the center of the bottom section 2. The top of the top telescopic pole section 4 is fixedly connected to the aerial work platform. The top of the top telescopic pole section 4 is closed, with connection holes for connecting to the aerial work platform via fasteners. A set of telescopic pole devices is connected to the bottom of each of the four corners of the aerial work platform for support. To improve the support effect, the number of telescopic pole devices can be increased. Two sets of symmetrically arranged support arc plates 5 are fixedly connected to the inner walls of the bottom section 2 and the middle section 3. Multiple sets of adjusting arc plates 6 are fixedly connected to the outer walls of the middle section 3 and the top section 4. Two sets of symmetrically arranged adjusting arc plates 6 are set at the same height. Through the arrangement of the support arc plates 5 and the adjusting arc plates 6, when the middle section 3 is rotated so that the adjusting arc plates 6 on the outer ring of the middle section 3 press against the support arc plates 5 on the inner ring of the bottom section 2, the middle section 3 is supported. Similarly, other sets of middle sections 3 and the top section 4 can be supported. Since the lengths of both the supporting arc plate 5 and the adjusting arc plate 6 are less than a quarter circle, after rotating the middle section 3 of the telescopic rod, the adjusting arc plate 6 on its outer ring can be moved away from the supporting arc plate 5 on the inner ring of the bottom section 2 of the telescopic rod. This allows the middle section 3 of the telescopic rod to be moved to adjust its length extending beyond the bottom section 2. Similarly, the extension lengths of the middle sections 3 and the top section 4 of the other sets of telescopic rods can be adjusted, thereby adjusting the overall length of the device to adapt to the height difference of the stairs and making the high-altitude operating platform installed on the top of the multiple sets of telescopic rod devices stable. A limiting baffle 61 is fixedly connected to the bottom of the adjusting arc plate 6. Through the positioning function of the limiting baffle 61, when it is necessary to move the adjusting arc plate 6 above the supporting arc plate 5 and rotate the telescopic rod intermediate section 3, the adjusting arc plate 6 first presses against the supporting arc plate 5. Then, the telescopic rod intermediate section 3 is rotated so that one side of the limiting baffle 61 contacts the supporting arc plate 5, and the telescopic rod intermediate section 3 rotates into place. At this time, the contact area between the adjusting arc plate 6 and the supporting arc plate 5 is at its maximum, and the safety insertion hole 7 on the bottom section 2 and the telescopic rod intermediate section 3 are aligned. When it is necessary to move the adjusting arc plate 6 away from the supporting arc plate 5, the telescopic rod intermediate section 3 is rotated in the opposite direction so that the other side of the limiting baffle 61 contacts the other end of the supporting arc plate 5, facilitating the movement of the telescopic rod intermediate section 3 within the telescopic rod bottom section 2 to adjust the extension length. Similarly, the inner telescopic rod intermediate section 3 and the telescopic rod top section 4 are supported and adjusted.

[0023] Furthermore, the aforementioned telescopic pole device also includes multiple positioning components 8, which are installed in the safety socket 7 to prevent rotation of the bottom section 2 and the middle section 3 of the telescopic pole. The positioning component 8 includes a safety pin 81 that passes through the safety socket 7. The safety pin 81 is L-shaped, and its L-shape prevents it from moving to one side after being inserted into the safety socket 7. One end of the safety plug 81 is threadedly connected to a threaded rod 82. The end of the threaded rod 82 away from the safety plug 81 is fixedly connected to a rotating rod 83. The rotating rod 83 facilitates the rotation of the threaded rod 82. At the same time, after the threaded rod 82 is threaded into the safety plug 81, the rotating rod 83 prevents the safety plug 81 from moving to the other side, thereby confining the safety plug 81 in the safety socket 7. This prevents relative rotation of the bottom section 2, the middle section 3, and the top section 4 of the telescopic rod, thus avoiding the adjustment arc plate 6 from being moved off the support arc plate 5 due to rotation after it is pressed on the support arc plate 5, ensuring the supporting effect of the support arc plate 5.

[0024] In this embodiment, the support base 1 is first placed on the construction ground. The support base 1 ensures that the entire device is placed stably, providing a stable foundation for subsequent adjustment operations. When the device is in use, a set of telescopic rod devices are connected to the bottom of each of the four corners of the aerial work platform. If necessary, the number of telescopic rod devices can be increased to improve support stability. The top section 4 of each telescopic rod device is fixedly connected to the aerial work platform through the connecting hole and fastener at the closed end. Before adjustment, rotate the middle section 3 or the top section 4 of the telescopic rod in the opposite direction, so that the adjusting arc plate 6 on the outer wall of the middle section 3 and the adjusting arc plate 6 on the outer wall of the top section 4 move synchronously with the rotation until the other side of the limiting baffle 61 at the bottom of the adjusting arc plate 6 contacts the other end of the supporting arc plate 5 on the inner wall of the bottom section 2 of the telescopic rod and the supporting arc plate 5 on the inner wall of the middle section 3 of the inner telescopic rod. At this time, the adjusting arc plate 6 is completely removed from above the supporting arc plate 5, releasing the support limitation. Subsequently, depending on the height difference of the stairs, the middle section 3 or the top section 4 of the telescopic rod can be pulled up or down to adjust the length of the extension of the bottom section 2 or the middle section 3 of the outer telescopic rod, thereby changing the overall length of the device to adapt to the height required by the high-altitude operating platform.

[0025] Then, rotate the middle section 3 or the top section 4 of the telescopic rod forward, causing the adjusting arc plate 6 to rotate above the supporting arc plate 5. When one side of the limiting baffle 61 contacts the supporting arc plate 5, the middle section 3 or the top section 4 of the telescopic rod rotates into place. At this time, the contact area between the adjusting arc plate 6 and the supporting arc plate 5 is at its maximum, forming a stable support structure to bear the load transmitted by the aerial work platform. At the same time, the safety holes 7 on the bottom section 2, the middle section 3, and the top section 4 of the telescopic rod automatically align, and the safety bolt 81 in the positioning assembly 8 is inserted into the aligned safety hole 7. The L-shaped structure of the safety bolt 81 prevents it from moving to one side. Then, by rotating the rotating rod 83, the threaded rod 82 is rotated to make the threaded rod 82 threadedly connected to the safety plug 81. The rotating rod 83 prevents the safety plug 81 from moving to the other side, thereby firmly confining the safety plug 81 within the safety socket 7, avoiding relative rotation of the sections of the telescopic rod, ensuring that the adjusting arc plate 6 is always stably pressed on the supporting arc plate 5, and ensuring the support effect of the device and the safety of operation.

[0026] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
