Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic assembly installation, and in particular to a pipe pile cantilever safety platform and an installation method thereof. Background Art

[0002] Prefabricated pipe piles are one of the most common forms of pile foundations for photovoltaic construction projects and are widely used. For the "tea-photovoltaic complementary" construction project, the height of the prefabricated pipe piles needs to be considered in combination with the safe net height of mechanical tea picking. Generally, the height of the prefabricated pipe piles is above 3.5m. At this height, personnel cannot stand on the ground to perform installation operations, and a safe operating platform needs to be set up to install photovoltaic modules. However, tea gardens are mostly mountainous, with rugged and uneven ground and a certain slope. The erection of movable scaffolding is extremely inconvenient and poses a safety hazard. Therefore, the development of a photovoltaic module installation operation platform suitable for sloping ground and high pipe pile foundation is a technical problem that needs to be solved urgently.

Compared with the traditional clamping method, the friction self-locking device has a higher bearing capacity and a stable and safe structure.

[0007] Furthermore, there are 12 horizontal support arms evenly distributed along the circumference, and the angle between adjacent horizontal support arms is 30°.

[0008] Furthermore, the platform is a modular steel structure platform, which can achieve rapid assembly and disassembly of the steel platform.

[0032] Example

[0033] See also Figures 1 to 3 The present embodiment provides a pipe pile cantilever safety platform, wherein upper friction self-locking nodes and lower friction self-locking nodes are distributed on the upper and lower outer walls of the pipe pile 3; the upper friction self-locking nodes are evenly connected to a number of horizontal support arms 12 toward the outer periphery; a platform 7 is installed on the upper surface of the horizontal support arm 12; a platform plate 11 is installed on the top surface of the platform 7, and a guardrail 8 is provided on the outer edge; an adjustable support rod 9 connects the lower friction self-locking node and the horizontal support arm 12 to form a triangular support structure under the horizontal support arm 12; the upper friction self-locking node and the lower friction self-locking node both include a wedge-shaped slider 5 and a friction self-locking clamp 6; the inner diameter of the wedge-shaped slider 5 is the same as the outer diameter of the pipe pile 3, and the whole is circular, adopts a semicircular structure design, and is fixed to the outer wall of the pipe pile 3 by clamping with a hoop; the friction self-locking clamp 6 is two semicircular wedge-shaped blocks, whose wedge surfaces are complementary to the wedge surfaces of the wedge-shaped slider 5, and are fixed to the outer wall of the wedge-shaped slider 5 by clamping with a hoop.

[0034] The technical principle of the safety platform is: the friction self-locking device is used as a fulcrum, and the adjustable support rod is used as a support to detachably and firmly connect the horizontal support arm of the platform to the pipe pile, so as to stably carry the load of the platform. When the friction self-locking clamp of the friction self-locking device is subjected to its own weight and upper load, the friction self-locking clamp moves downward, and maintains a continuous friction and compression state with the wedge-shaped slider during the movement. The friction force is directed upward, and then stable self-locking is achieved, and it is firmly fixed on the pipe pile. Compared with the traditional clamping method, the friction self-locking device has a higher bearing capacity and a stable and safe structure.

[0035] As a preferred technical solution, 12 horizontal support arms 12 are evenly distributed along the circumference, and the angle between adjacent horizontal support arms is 30°. The distribution density of the load-bearing support arms meets the safety requirements for safe operation of personnel.

[0036] As a preferred technical solution, the platform 7 is a modular steel structure platform, which can realize rapid assembly and disassembly of the steel platform.

[0037] As a preferred technical solution, see Figure 4The guardrail 8 adopts a sleeve insertion connection mode, and the base of the sleeve 13 is fixed on the platform 7. When in use, the shaped railing is inserted into the sleeve at the bottom, the bolts are tightened, and the railing can be removed by loosening the bolts, which is convenient for installation and removal.

[0038] As a preferred technical solution, see Figure 5 The adjustable support rod 9 is composed of an internal threaded sleeve 91 on both sides and a matching screw rod 92 in the middle, and a nut 93 is fixed in the middle of the screw rod 92. The function of adjusting the length of the support rod is achieved by rotating the nut forward and backward.

[0039] As a preferred technical solution, see Figure 1 and Figure 5 An ear plate 14 is provided on the outer periphery of the lower friction self-locking node and at a position corresponding to the horizontal support arm 12 to provide a support connection point; connecting rings 94 are provided at both ends of the adjustable support rod 9, and the lower friction self-locking node and the horizontal support arm 12 are connected by the ear plate 14, the connecting ring 94 and bolts to form a triangular support structure under the horizontal support arm 12.

[0040] See also Figure 1 , Figure 2 and Figure 6 The pipe piles 3 of the photovoltaic support 2 are prefabricated on the sloped ground 4, and then the above-mentioned pipe pile cantilever safety platform is installed. The more specific installation method includes the following steps:

[0041] Step S1, according to the height of the installer, confirm the position of the upper friction self-locking node and the upper friction self-locking node, and install the upper and lower pairs of wedge-shaped sliders 5, and fix them on the outer wall of the pipe pile 3 with the first connecting clamping piece 15.

[0042] Step S2, installing two pairs of upper and lower friction self-locking clamps 6, and using the second connecting clamping piece 10 to fix and clamp them on the outer wall of the wedge-shaped slider 5.

[0043] Step S3, evenly distribute and connect the horizontal support arms 12 on the outer circumference of the friction self-locking clamp 6. Figure 2 The preferred connection method is bolt connection.

[0044] Step S4, install the adjustable support rod 9 between the horizontal support arm 12 and the upper friction self-locking node. The adjustable support rod can use a screw with a larger diameter to meet the requirement of providing auxiliary support for the horizontal support arm. Preferably, the adjustable support rod is designed with a "positive and negative thread structure" and a nut is fixed in the middle; when the nut rotates forward and backward, the connection mechanisms on both sides will be extended and retracted, thereby achieving length adjustment.

[0045] Step S5, the platform 7, the platform plate 11 and the guardrail 8 are installed on the horizontal support arm 12. More specifically, a detachable steel structure platform 7 is installed on the horizontal support arm 12, and a platform plate 11 is installed on the top of the platform 7. The platform 7 and the platform plate 11 are fixedly connected to the horizontal support arm structure by bolts. A detachable guardrail sleeve 13 is installed around the detachable platform 7; when in use, the detachable guardrail 8 is inserted into the sleeve at the bottom and the bolts are tightened. When dismantling, first loosen the bottom bolts to remove the guardrail.

[0046] After the safety platform is assembled, construction workers can stand on the platform board 11 to install the photovoltaic bracket 2 and the photovoltaic panel 1.

[0047] From the above construction process, it can be known that the cantilever safety platform of the present invention is suitable for prefabricated pipe pile operations with a high excavation height. It is relatively convenient to manufacture and install, and can be quickly used in a turnover manner.
