DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] like Figure 1 and Figure 2As shown, an embodiment of the utility model includes: a mounting bracket 1, the mounting bracket 1 includes at least four vertically placed columns 11, the projection points of the center lines of the columns 11 in the vertical direction are respectively the vertices of the rectangle, one side of the column 11 is perpendicular to the diagonal of the rectangle, and the sides of the columns 11 that are perpendicular to the same diagonal of the rectangle are parallel to each other; a loading component 2 arranged on the mounting bracket 1, the loading component 2 includes at least four first rollers 26, and the pressure action lines of the sides of the first rollers 26 on the columns 11 coincide with the diagonals of the rectangle respectively; and a conveying component 3 arranged on the loading component 2, the conveying component 3 forms a horizontal conveying surface.

[0024] Specifically, this embodiment includes four columns 11, the cross section of each column 11 is a rectangle, and the line connecting the center line projections of the four columns 11 forms a rectangle. Figure 2 The dotted lines in the figure represent the projection lines and diagonals respectively. The four columns 11 have relative side faces A which are respectively perpendicular to the diagonals of the rectangle, and the side faces A on the same diagonal are parallel to each other. Secondly, the side face opposite to the side face A in the column 11 is the side face B. The side faces of the four first rollers 26 are respectively tangent to the four side faces B and rolling friction is formed. The first rollers 26 exert pressure on the side faces B of the column 11 when rolling thereon. The pressure can be decomposed according to the relationship between the sides and angles of the rectangle to obtain a component force in a vertical direction. The component force is respectively parallel to the side length of the rectangle, and the sum of the component forces in parallel directions is zero, so that the four columns 11 can limit the horizontal movement of the four first rollers 26, so that the loading assembly 2 will not shake when moving up and down along the column 11, and so that the photovoltaic assembly will not shift in position during the lifting process, which is convenient for the next process to operate it.

[0025] like Figure 3 As shown, the conveying component 3 includes: a conveyor belt 31 connected to the bottom end of the loading component 2, the top surface of the conveyor belt 31 is a horizontal plane, and the conveyor belt 31 can convey the photovoltaic components to the carrying range of the loading component 2; side guides 32 connected to the two side surfaces of the conveyor belt 31 along the conveying direction, and the conveying direction of the side guides 32 is the same as the conveying direction of the conveyor belt 31; and sensors 33 arranged at both ends of the side guides 32 along the conveying direction, and the sensors 33 can detect whether there is a ground cow placed on the conveyor belt 31 and whether the placement position of the ground cow is within the carrying range of the loading component 2.

[0026] Specifically, the conveyor belt 31 is a belt or chain drive, which has three belts or chains arranged in parallel, and the ground cows are placed in the gaps between each other. The conveying surface of the conveyor belt 31 coincides with the top surface of the ground cow, so that the conveyor belt 31 rotates to drive the photovoltaic components to separate from the ground cow; secondly, the side guide 32 is a roller drive, and its axis is placed vertically. When the ground cow loads the photovoltaic components and enters the conveyor belt 31, the side guide 32 can limit the movement of the photovoltaic components in the vertical forward direction and assist the conveyor belt 31 to move it along the conveying direction; secondly, infrared The sensor 33 can identify the position of the ground bull relative to the side guide 32, and then determine the position of the photovoltaic components placed on the ground bull relative to the loading frame 24, and then can transmit the photovoltaic components to the middle position of the conveyor belt 31, so that the center of the stacked photovoltaic components falls on the center position of the loading frame 24, and then the four corners of the loading frame 24 exert the same pressure on the column 11 through the first roller 26 and the second roller 27, and then the friction forces on the four corners of the loading frame 24 are the same, and then the loading distances are the same, thereby improving the stability of its loading.

[0027] like Figure 4 As shown, the loading assembly 2 also includes a loading frame 24 for carrying the photovoltaic assembly. The loading frame 24 is connected to the axis connected to the first roller 26. The side of the first roller 26 rolls along the side of the column 11 to drive the loading frame 24 to move along the length direction of the column 11.

[0028] Specifically, the loading platform of the loading frame 24 moves up and down within the area enclosed by the plane of the side A of the column 11, and the first roller 26 is fixedly connected to the four corners of the loading frame 24 by bolts, so that the column 11 applies a supporting force to the loading frame 24 through the side A, and the directions of the supporting force are the diagonal directions of the rectangle, so that when the loading frame 24 moves up and down relative to the side of the column 11 through the first roller 26, the supporting force can limit the horizontal movement of the loading frame 24, so that the loading frame 24 will not shake during the movement, and the photovoltaic components placed on the loading platform of the loading frame 24 will not be shifted in position.

[0029] Furthermore, the loading assembly 2 also includes a second roller 27 whose axis is connected to the loading frame 24, and the side surfaces of a single column 11 are connected to the same number of first rollers 26 and the second rollers 27, and the combined force directions of the pressure exerted by the side surfaces of the first roller 26 on the column 11 and the pressure exerted by the side surfaces of the second roller 27 on the column 11 are parallel.

[0030] Specifically, the side surface of the first roller 26 contacts the opposite surface of the side surface A, and the side surface of the second roller 27 contacts the vertical surface of the side surface A, wherein the directions of the resultant forces of the support forces exerted by a single column 11 on the first roller 26 and the second roller 27 are parallel and equal in magnitude, and thus the resultant force of the support forces exerted by the four columns 11 is zero, so that the second roller 27 can further constrain the positional relationship between the loading frame 24 and the column 11, thereby further reducing the shaking of the loading frame 24 during the loading process, and improving the position accuracy of the photovoltaic components relative to the loading platform during the process of lifting the photovoltaic components in this embodiment.

[0031] like Figure 5 As shown, the loading assembly 2 also includes: a counterweight 25 connected to the side of the column 11, the weight of the counterweight 25 is adjustable, the counterweight 25 moves in the vertical direction of the column 11, and the movement directions of the counterweight 25 and the loading frame 24 are opposite and the movement speeds are the same; a first chain 21 connected to one side of the loading frame 24 at one end, the other end of the first chain 21 is connected to the counterweight 25, and both ends of the first chain 21 move in the vertical direction of the column 11; a second chain 22 connected to the opposite side of the loading frame 24 at one end, the other end of the second chain 22 is connected to the counterweight 25.

[0032] Specifically, the first roller 26 and the second roller 27 are fixedly connected to the end surface of the counterweight 25 by screws, and the column 11 applies a supporting force to the counterweight 25 through the first roller 26 and the second roller 27, thereby limiting its horizontal movement, leaving only the vertical degree of freedom; secondly, the motor drives the sprocket to rotate, and the sprocket drives the first chain 21 and the second chain 22 to rotate, and the first chain 21 and the second chain 22 change their own movement directions through the sprocket, so that the movement speeds of the two are the same but the movement directions are opposite, wherein the counterweight 25 and the first chain 21 and The vertically downward ends of the second chains 22 are connected by bolts, so that they can cooperate with the motor to increase the movement speed of the first chain 21 and the second chain 22, thereby increasing the movement speed of the other ends of the first chain 21 and the second chain 22. The ends are connected to the opposite sides of the loading frame 24 by bolts, so that the motor and the counterweight 25 drive the first chain 21 and the second chain 22 to move and then drive the loading frame 24 to move vertically upward through the first sprocket and the second sprocket, thereby increasing the rising speed of the loading frame 24 and improving the efficiency of lifting the photovoltaic components.

[0033] like Figure 6 As shown, the loading assembly 2 also includes a compression spring 23 connected to one end of the first chain 21 and the second chain 22 respectively, and the other end of the compression spring 23 is connected to the loading frame 24. When the first chain 21 and the second chain 22 move vertically upward, the compression spring 23 is compressed.

[0034] Specifically, the first chain 21 and the second chain 22 begin to drive the loading frame 24 to move vertically upward, and they first compress the compression spring 23 to absorb the impact at startup, thereby reducing the impact on the photovoltaic module. When the other ends of the first chain 21 and the second chain 22 are connected to the counterweight 25 and move vertically downward to a limited position, the loading frame 24 continues to move vertically upward under the action of inertia, and it compresses the compression spring 23 to absorb the upward impact, thereby reducing the impact on the photovoltaic module.

[0035] Furthermore, the mounting bracket 1 also includes: a maintenance ladder 12 connected to the column 11, the length direction of the maintenance ladder 12 is the vertical direction, and a maintenance platform 13 arranged on the top end surface of the column 11, and the space where the maintenance platform 13 is located is connected to the space where the power parts of the loading assembly 2 are located.

[0036] Specifically, the maintenance ladder 12 is connected to the side of the column 11 by bolts, and its top is not lower than the top of the column 11, so that maintenance personnel can enter the maintenance platform 13 through the maintenance ladder 12, and then maintain and repair the first chain 21, the second chain 22 and the motor.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
