DETAILED DESCRIPTION

[0062] Example 1:

[0063] The preferred solution is Figures 1 to 4 As shown, a mounting platform for convenient cross-beam operation includes a U-shaped hook 2 and a pedal 1, the number of the U-shaped hooks 2 is at least three, the number of the pedals 1 is at least two, and the U-shaped hook 2 is used to hang on the rope 3;

[0064] In the case where a cross beam is not required, the two U-shaped hooks 2 are located on the same side of the support beam 4, and the two pedals 1 are mounted on the two U-shaped hooks 2;

[0065] When a cross-beam is required, two U-shaped hooks 2 are located on one side of the support beam 4 , and the third U-shaped hook 2 is located on the other side of the support beam 4 , and the two pedals 1 are transferred to the third U-shaped hook 2 in sequence.

[0066] Rope 3 is a steel cable, which is divided into photovoltaic module fixing steel cable and load-bearing steel cable. The photovoltaic module fixing steel cable is used to install photovoltaic modules, and the load-bearing steel cable is used to install photovoltaic wind-resistant support poles. U-shaped hook 2 is used to hang on the photovoltaic module fixing steel cable. The height distribution of the two photovoltaic module fixing steel cables is determined by the installation angle of the photovoltaic module. U-shaped hook 2 is made of a bent metal rod, such as Figure 4 As shown, two steps 1 are placed on two U-shaped hooks 2, providing a platform for workers to stand on while installing photovoltaic modules. In this embodiment, the steps 1 are ordinary steel plates or mesh panels. The support beam 4 is used to install the steel cables and is the supporting component of the entire flexible photovoltaic module. When the operator needs to move from one end of the support beam 4 to the other end to perform work, the cross-beam operation is as follows:

[0067] In this embodiment, a method for installing a platform for cross-beam operation is provided, and the steps are as follows:

[0068] In front of the span beam, two U-shaped hooks 2 are located on the same side of the support beam 4 and are hooked to ropes 3. Two steps 1 are placed on the two U-shaped hooks 2. Operators wearing safety belts stand on the steps 1 to work, with the hooks of the safety belts hooked to the ropes. At least three operators are required: Operator A, Operator B, and Operator C. The two steps 1 are Step D and Step F.

[0069] When cross-beam operation is required, the operating steps are as follows:

[0070] S1: Operator A first steps over support beam 4 and hooks the third U-shaped hook 2 onto rope 3 on the other side of support beam 4. Operator A stands on rope 3, which includes a PV module fixing cable and a load-bearing cable. Operator A stands on the load-bearing cable and holds onto the PV module fixing cable. The hook of the mounting strap is hooked onto the PV module fixing cable.

[0071] S2: Operator B on the ground holds the jack 5, slightly lifts the D pedal and pushes it toward the third U-shaped hook 2 until the D pedal is placed on the third U-shaped hook 2;

[0072] While the above step S2 is being executed, operator C stands on pedal F and pushes pedal D forward;

[0073] S3: Repeat the process of step 2. Operator B holds the push rod 5, slightly lifts the F pedal and pushes it in the direction of the third U-shaped hook 2 until the F pedal is placed on the third U-shaped hook 2.

[0074] While the above step S3 is being executed, operator C stands on rope 3 and pushes pedal D forward.

[0075] Operator A can help operators B and C to pull by tying the traction rope to pedals D and F.

[0076] The above-mentioned letter numbers are used to distinguish the numbers of the same type of people or the same type of tools, and are not technical features of the present invention.

[0077] Example 2:

[0078] The pedal 1 in this embodiment is a conventional plate-type structure and is relatively heavy. It is difficult to move the pedal 1 if only two people working at height are involved. This is due to both its weight and the high friction between it and the U-shaped hook 2. Therefore, it requires assistance from a ground operator, who must use a jack 5 to lift the pedal 1. Furthermore, the connection between the pedal and the U-shaped hook 2 is unreliable, posing a safety hazard. To address the shortcomings of the pedal in Example 1, this embodiment incorporates the following improvements:

[0079] like Figure 6-15 As shown, the bottom surface of the pedal 1 is provided with a limiting groove 101, which is used to be placed on the U-shaped hook 2. The limiting groove 101 is stuck in the bottom of the U-shaped hook 2, avoiding the pedal 1 from being separated from the U-shaped hook 2.

[0080] Furthermore, a threaded hole is provided on the pedal 1, which is connected to the limiting groove 101. A top screw 104 is installed on the threaded hole, and the top screw 104 is connected to the adjustment cap 105. When the pedal 1 needs to be moved, the adjustment cap 105 is rotated, and the top screw 104 moves downward to disengage the U-shaped hook 2 from the limiting groove 101.

[0081] Furthermore, a slide bar 102 is provided on the bottom surface of the pedal 1. When the pedal 1 slides on the U-shaped hook 2, the slide bar 102 contacts the rod of the U-shaped hook 2. Since the slide bar 102 greatly reduces the contact surface with the U-shaped hook 2, the sliding friction is greatly reduced.

[0082] Furthermore, the bottom surface of the pedal 1 is provided with a push rod matching groove 103, which is used to match the push rod 5. The push rod matching groove 103 is used to provide a fulcrum for the push rod 5. This design is optional. When the assistance of the operator on the ground is required, the operator on the ground can insert the push rod 5 into the push rod matching groove 103 to operate.

[0083] Furthermore, the pedal 1 includes a left pedal and a right pedal. The left pedal is provided with a left slide bar 106 and a left slot 107, while the right pedal is provided with a right slide bar 108 and a right slot 109. The left slide bar 106 is configured to slide within the right slot 109, while the right slide bar 108 is configured to slide within the left slot 107. The pedal 1 is designed as a two-piece telescopic structure. When the pedal 1 is moved, one piece is first extended, and then the other piece is retracted. This reduces the weight of the pedal 1 each time it is moved, and in particular, when there is no ground operator to assist, the transfer can be accomplished by two operators working at height alone.

[0084] A left-handle 110 is rotatably mounted on the end of the left slider 106, while a right-handle 111 is rotatably mounted on the end of the right slider 108. The left slot 107 communicates with the left handle placement slot 112, while the right slot 109 communicates with the right handle placement slot 113. The right slider 108 is fixedly connected to the right pedal, while the left slider 106 is fixedly connected to the left pedal. To prevent the left and right pedals from disengaging, a rotatable handle is designed. The handle comprises a left-handle 110 and a right-handle 111. The left-handle 110 is rotatably mounted on the left slider 106. When the left and right pedals are closed, the left-handle 110 rotates into the right-handle placement slot 113. This prevents the left-handle 110 from obstructing the operator's movement and acts as a limiter. Furthermore, the left-handle 110 provides the operator with a grip that allows for force. The right-handle 111 functions the same way as the left-handle 110. In this embodiment, the handles and sliders may be connected via bearings.

[0085] like Figure 16-21 As shown, when there are no extra operators to assist on the ground or the ground conditions are not convenient for standing, the present invention provides a beam-spanning method for installing a platform that facilitates beam-spanning operation, including the following steps:

[0086] In front of the span beam, two U-shaped hooks 2 are located on the same side of the support beam 4 and are hooked to ropes 3. Two pedals 1 are placed on the two U-shaped hooks 2. The operator wears a safety belt and stands on the pedal 1 to work, with the hook of the safety belt hooked to the rope. At least two operators are required, namely operator A and operator B. The two pedals 1 are pedal D and pedal F.

[0087] When cross-beam operation is required, the operating steps are as follows:

[0088] S1: Operator A first steps over the support beam 4 and hooks the third U-shaped hook 2 onto the rope 3 on the other side of the support beam 4; Operator A stands on the rope 3;

[0089] S2: Operator B stands on pedal F and rotates the adjusting cap 105 to disengage the limiting groove 101 of pedal D from the U-shaped hook 2;

[0090] S3: Operator B rotates the left rotation handle 110 and the right rotation handle 111 to an upward state, so that the left rotation handle 110 slides on the right slot 109 and the right rotation handle 111 slides on the left slot 107;

[0091] S4: Operator B pushes the left rotation handle 110 or the right rotation handle 111 of the D pedal to extend the D pedal until it reaches the third U-shaped hook 2;

[0092] S5: Operator A overlaps the D pedal on the third U-shaped hook 2, rotates the adjustment cap 105, overlaps the limiting groove 101 on the U-shaped hook 2, and then pulls the left rotation handle 110 or the right rotation handle 111 to shorten the D pedal;

[0093] During step S5, operator B overlaps the limiting groove 101 at the other end of pedal D with a U-shaped hook 2 in the middle;

[0094] S6: Operator B stands on the rope 3 and rotates the adjusting cap 105 to disengage the limiting groove 101 of the F pedal from the U-shaped hook 2; repeating steps S3-S5 to transfer the F pedal to the third and middle U-shaped hooks 2;

[0095] The span beam ends.

[0096] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
