Technical Field

[0001] The utility model relates to a prefabricated wall panel transport frame, in particular to a wall panel transport frame anti-collapse structure. Background Art

[0002] The wall panels of prefabricated buildings are usually produced and processed in prefabrication plants, and then transported to the construction site by transport vehicles, where they are directly assembled on site to complete the construction of the house. When transporting prefabricated wall panels, wall panel transport racks are required.

[0003] Chinese patent ZL202320027999.3 discloses a foldable wall panel transport rack, which positions the wall panel at both ends only by limiting components. This positioning method is only suitable for temporarily fixing the wall panel. When encountering a transportation condition such as sea transportation where there is a large shaking in all directions, it is obviously not enough to only use the limiting components (latch rods) to fix the two ends of the wall panel. Auxiliary support must be added in the middle of the wall panel to prevent the wall panel from cracking in the middle. Utility Model Content

[0029] The present invention is further described below in conjunction with specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] See also Figure 1 - Figure 6 An embodiment of the wall panel transport frame anti-collapse structure of the utility model comprises a base frame 1, the length of which is adapted to the length of the wall panel. A plurality of pairs of first supports 2 are fixedly installed on both sides of the base frame 1, and a column 3 is hingedly installed on the first support 2, so that the column 3 can be unfolded relative to the base frame 1 in a vertical state, or folded toward the base frame 1 and retracted into the base frame 1. A wall panel support seat 4 is installed on the inner side of the column 3 through a telescopic structure, a limiting boss 31 is arranged on the outer side of the column 3, and a limiting seat 11 is arranged on the upper surface of the base frame 1. When the column 3 is unfolded, the limiting boss 31 is supported by the upper surface of the base frame 1, and can bear the load of the column 3 tilting outward, and a first pin hole 311 is arranged on the limiting boss 31, and a second pin hole 111 is arranged on the limiting seat 11. When the column 3 is unfolded, the first pin hole 311 and the second pin hole 111 are connected together by a positioning pin 5, so that the column 3 is kept in a vertically unfolded state.

[0033] The telescopic structure includes a connecting rod 6 and a telescopic rod 7, one end of the connecting rod 6 and one end of the telescopic rod 7 are respectively hinged to the column 3, and the other end of the connecting rod 6 and the other end of the telescopic rod 7 are respectively hinged to the wall panel support seat 4. A buffer pad (rubber skin) is fixedly installed on the supporting surface of the wall panel support seat 4 to prevent it from causing damage to the wall panel when it contacts the wall panel.

[0034] The second support 8 is installed on the column 3, and a plurality of fixing holes 81 are arranged on the second support 8 along the axis direction of the column. The telescopic rod 7 is selectively connected to one of the fixing holes 81 through a fixing pin 82. When it is necessary to significantly adjust the thickness of the wallboard clamped by the wallboard anti-collapse structure of the utility model, it can be achieved by replacing different fixing holes 81. When the wallboard anti-collapse structure of the utility model needs to be folded and retracted, the telescopic rod 7 can be hinged to the lowest fixing hole 81 on the second support 8, so that the telescopic rod 7 and the connecting rod 6 just form a straight line, which can save folding space.

[0035] The telescopic rod 7 comprises a first sleeve 71, a second sleeve 72 and a stud 73. The first sleeve 71 and the second sleeve 72 have internal threads with opposite thread directions, and the first sleeve 71 and the second sleeve 72 are respectively threadedly connected to one end of the stud 73 and are respectively locked with a locking nut 74. A square head 75 is provided in the middle of the stud 73 for convenient wrench clamping. Without disassembling the first sleeve 71 and the second sleeve 72, the length of the telescopic rod 7 can be adjusted by rotating the square head 75. When the telescopic rod 7 is adjusted to the desired length, the first sleeve 71 and the second sleeve 72 can be locked with the locking nut 74 so that the length of the telescopic rod 7 no longer changes.

[0036] One end of the locating pin 5 has a head, and the other end is provided with a limiting groove 51. A limiting card 9 is hingedly installed on the first support 2. After the locating pin 5 is inserted into the first pin hole 311 and the second pin hole 111, the limiting card 9 is inserted into the limiting groove 51 to fix the locating pin 5 and prevent the locating pin 5 from falling off.

[0037] A return spring 10 is installed between the limit card 9 and the first support 2 to achieve automatic insertion of the limit card 9 .

[0038] The first support 2 is installed in the base frame 1, and a support plate 21 is set in the first support 2. The first support 2 is symmetrically installed on both sides of the base frame 1. When the column 3 is folded, the column 3 is completely retracted into the base frame 1, and the upper end of the column 3 is placed on the support plate 21 of the first support 2 on the opposite side.

[0039] When the utility model is used, the side of the wallboard on the wallboard transport rack can be supported and reinforced, and the distance of the wallboard supported (clamped) by the utility model can be infinitely adjusted through the telescopic structure, so that it can be well adapted to the situation where different numbers of wallboards are placed in the wallboard transport rack. When the transport rack needs to be folded and transported back to the departure place, the upright column of the utility model can be folded and stored in the bottom frame of the wallboard transport rack, without affecting the occupied space of the wallboard transport rack.
