Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic brackets, and particularly relates to a positioning tooling and a using method for the legs of a photovoltaic bracket. Background Art

[0002] For the brackets of a photovoltaic system, the overall bracket is relatively large and mainly consists of front legs, rear legs, diagonal beams at the tops of the front legs and rear legs, reinforcement beams between the diagonal beams and the rear legs, and cross beams at the top of the diagonal beams. The photovoltaic frame is fixed on the linearly arranged cross beams.

[0003] For the installation of the front legs and rear legs, connecting pieces such as flange plates are arranged at the bottom ends of the legs and fixed on the ground. If the reinforcement requirements are relatively high, a concrete base also needs to be poured between the legs and the ground surface.

[0004] Since it is necessary to ensure the parallelism and flatness of the surface formed by the cross beams on the bracket, the slope and position accuracy requirements of the diagonal beams for support are also relatively high, and thus the position accuracy requirements of the legs are also relatively high.

[0005] Since the number of legs is also relatively large, a large amount of measurement and positioning of the legs need to be carried out by workers during installation, which will affect the installation efficiency of the workers. At the same time, manual assistance is required to ensure the perpendicularity of the legs to the ground during installation, which is not conducive to the operation of the workers, wastes manpower and affects the installation efficiency. Summary of the Invention

[0006] The purpose of the invention is to provide a positioning tooling for the legs of a photovoltaic bracket. By designing a new type of cross beam tooling, the cross beam can be positioned and restricted. Through the cooperation of the leg tooling and the cross beam, the legs are limited and positioned. The cross beam required for using the photovoltaic bracket is used as the guide and positioning for the linear arrangement of the legs, which is conducive to the operation of the workers, eliminates the need for redundant positioning and limiting, facilitates the installation of the legs by the workers, and saves the use of manpower and material resources.

[0007] To solve the above technical problems, the invention is realized through the following technical solutions:

[0008] The invention is a positioning tooling for the legs of a photovoltaic bracket, including a leg tooling and a cross beam tooling;

[0009] The leg tooling includes a U-shaped seat, side plates and clamping edges;

[0010] An edge seat is fixed at one side edge of the U-shaped seat. The edge seat is vertically arranged and perpendicularly distributed to the side of the U-shaped seat. A hole is opened on the end face of the edge seat, and an elastic rod is arranged in the hole. A fastening screw is arranged on the other side of the U-shaped seat;

[0011] One ends of a plurality of the elastic rods penetrate and are fixed at the edges of the side plates. The side plates are perpendicularly distributed to the edge seats;

[0012] The card edge is fixed to the end face of the side plate by screws. The card edge is distributed parallel to the side plate, and an adjustable cushion block is provided between the card edge and the side plate;

[0013] The crossbeam tooling includes columns;

[0014] A counterweight is fixed to the bottom end of the column, a U-shaped frame is provided at the top end of the column, and a rubber layer or a silica gel layer is provided on the inner surface of the U-shaped frame.

[0015] Further, the elastic rod member includes a rod body, a head is provided at one end of the rod body, and a spring is sleeved outside the rod body.

[0016] Further, a limiting ring is provided inside the end of the hole away from the U-shaped seat, and the inner diameter of the limiting ring is the same as the outer diameter of the rod body.

[0017] Further, the head is slidably arranged in the hole, and the spring is fixed between the limiting ring and the head.

[0018] Further, a pulling member is provided at the center of the surface of the side plate away from the side seat, and the pulling member is a T-shaped rod or a U-shaped handle.

[0019] Further, a plurality of anti-slip edges are provided inside the card edge, and rounded corners or chamfers are provided at both corners inside the card edge.

[0020] Further, the adjustable cushion block is a rectangular block body, screw holes are provided on the adjustable cushion block and the end face of the side plate away from the side seat, and the screw penetrates through the screw hole on the adjustable cushion block and is threadedly arranged in the screw hole on the side plate.

[0021] Further, a rotating handle is provided outside the screw head of the fastening screw, and anti-slip lines are provided on the circumferential side of the rotating handle.

[0022] Further, a plurality of blind openings are provided on the bottom surface of the U-shaped frame, a flange is provided at the top end of the column, and the U-shaped frame is fixed to the top end of the column through the flange, fasteners and blind openings.

[0023] Further, a method for using a positioning tooling for a leg of a photovoltaic support includes the following steps:

[0024] SS01 Take out the crossbeam on the photovoltaic support, and clamp the U-shaped frame on the crossbeam through the elastic force of the silica gel layer or the rubber layer;

[0025] SS02 Place the crossbeam with the crossbeam tooling on the ground, ensure that the U-shaped frame faces upward, and determine the levelness and specific position of the crossbeam through tools;

[0026] Put the U-shaped seat on the crossbeam with the opening facing downwards. Determine the position of the first leg using a tool. After the position is determined, tighten the fastening screws to ensure the position of the leg tooling on the crossbeam.

[0027] Pull the side plate to move the leg to be installed to the inner wall of the side seat. Release the side plate, and the side plate will be driven by the spring to reset and clamp the leg. At this time, the four sides of the leg are respectively in contact with the inner wall of the side plate, the inner wall of the clamping edge, the inner wall of the side seat, and the surface of the U-shaped seat close to the side seat.

[0028] Before clamping the leg in SS04, ensure that the bottom end of the leg is in contact with the ground. Open a hole in the ground using a tool, and install the flange at the bottom end of the leg on the ground through fasteners for pre-fixing the leg.

[0029] After the first leg is pre-fixed, disconnect the leg tooling from the crossbeam, and determine the position of the second leg in the length direction of the crossbeam. Install the second leg in the above-mentioned manner, and sequentially install all the legs at the outer side position of this crossbeam.

[0030] Switch the position of the crossbeam, and install the legs again according to the method of SS02 - SS06. After all the front legs and rear legs used for the photovoltaic support are pre-fixed, pour the base between the legs and the ground.

[0031] The present invention has the following beneficial effects:

[0032] 1. The present invention can position and limit the crossbeam by designing a new type of crossbeam tooling, and limit and position the legs through the cooperation of the leg tooling and the crossbeam. The crossbeam required for the photovoltaic support is used as the guide and positioning for the linear arrangement of the legs. Subsequently, the crossbeam can be recycled and reused. There is no need to measure and precisely control the linear arrangement of the legs, and only the distance between two adjacent legs needs to be controlled and measured, which is beneficial for the operation of the staff. There is no need for redundant positioning and limiting, ensuring the initial positioning during the installation of the photovoltaic support, facilitating the installation of the legs by the staff, and saving the use of manpower and material resources.

[0033] 2. The leg tooling designed in the present invention has the function of telescopic clamping of the side plate, which can be used for legs of different specifications, and at the same time has the function of clamping and fastening. At the same time, through the arrangement of adjustable pads, the adjustable pads can be replaced and modified according to the specifications of the legs during the initial use. The applicable range is relatively wide, and it is beneficial for the replacement and maintenance of each component, which can indirectly improve the service life of the tooling.

[0034] 3. The crossbeam tooling designed in the present invention does not require arranging fasteners between the tooling and the bottom surface through counterweights, and at the same time, the U-shaped frame can be detachably fixed to the column, and the specification of the U-shaped frame body can be replaced according to different specifications of crossbeams. The applicable range is relatively wide.
