[0027] like Figure 1-3 As shown, the steel bar cage with a limiting device proposed in the utility model includes a cage body 1.

[0028] The steel bar cage in this embodiment also includes: a limit plate assembly 2 installed on the inner side of the cage body 1 for limiting the cargo to prevent slipping and deviation, and an adjustment and limiting assembly 3 for positioning the installation position of the limit plate assembly 2 in the cage body 1. The limit plate assembly 2 can also be used as a partition to demarcate different intervals for classified transportation of cargo. Specifically:

[0029] The limit plate assembly 2 includes a limit plate 21, which is movably arranged in the cage body 1 to adjust the position according to the volume of the cargo. The limit plate 21 includes a first plate body 211 and a second plate body 212 that slides vertically in the first plate body 211. The connecting arm 22 is an inverted L-shaped structure, and one end of its horizontal section is fixedly connected to the second plate body 212. A fixing ear 23 is fixedly connected to the inner wall of the top end of the first plate body 211, and the height adjustment screw shaft 24 is threadedly screwed with the fixing ear 23 and the top end is rotatably engaged with the horizontal section of the connecting arm 22 through a bearing. When the height adjustment screw shaft 24 is rotated, the second plate body 212 can be moved up and down to adjust the height by screwing the height adjustment screw shaft 24 with the fixing ear 23, so as to adapt to cages of different heights.

[0030] The adjustment and limiting assembly 3 includes a latch 31 fixed to one side surface of the connecting arm 22. The cross section of the latch 31 is a V-shaped structure for adapting to the tooth groove of the latch bar 34. The latch bar 34 is detachably fixed to the outer wall of the cage body 1 by bolts. When the latch 31 and the tooth groove of the latch bar 34 are engaged with each other as shown in the figure, the horizontal position of the limit plate assembly 2 can be limited;

[0031] The adjustment and limiting assembly 3 also includes a limiting screw shaft 32 fixed to the bottom end of the vertical section of the connecting arm 22 and a guide bar 35 detachably fixed to the outer wall of the cage body 1 by bolts. The guide bar 35 is provided with a guide groove 351 for the limiting screw shaft 32 to movably penetrate and translate. A limiting nut 33 is threadedly engaged with the bottom end of the limiting screw shaft 32. The diameter of the limiting nut 33 is larger than the caliber of the guide groove 351. Therefore, the vertical position of the limiting plate assembly 2 can be limited after being tightened.

[0032] The outer wall of the cage body 1 is fixedly sleeved with the first fastening steel bar 4 and the second fastening steel bar 5. In the present embodiment, a groove for the first fastening steel bar 4 or the second fastening steel bar 5 to be inserted is provided on the surface of the slot bar 34 and the guide bar 35 facing the outer wall of the cage body 1. The groove can be used to limit the position of the first fastening steel bar 4 and the second fastening steel bar 5 to improve their stability.

[0033] The working principle of this embodiment is as follows: by adding a limit plate assembly 2 to the cage body 1, the cargo can be restricted to a certain area, and the potential safety hazard caused by the cargo offset leading to the cage imbalance can be avoided when an accident occurs during lifting, and the position of the limit plate assembly 2 can be adjusted according to the different volumes of the cargo. When adjusting, the limit nut 33 needs to be loosened or unscrewed, and the entire limit plate assembly 2 is lifted upward, so that the latching teeth 31 are separated from the current tooth grooves of the latching groove strip 34, and then the limit plate assembly 2 is translated to the appropriate position and then put down, so that the latching teeth 31 are re-engaged with the corresponding tooth grooves of the latching groove strip 34 to limit the horizontal position of the limit plate assembly 2, and then the limit nut 33 is tightened to limit the vertical position of the limit plate assembly 2.

[0034] In addition, the limit plate assembly 2 can be extended and retracted in the vertical direction, and the adjustment limit assembly 3 can be disassembled and assembled from the cage body 1, so that the limit plate assembly 2 can be applied to cages of different heights, thereby increasing the scope of application. Specifically, the height adjustment screw shaft 24 is rotated, and the second plate body 212 is moved upward by screwing the screw shaft 24 and the fixing ear 23 to increase the height of the limit plate assembly 2. Moreover, this method can also achieve the above-mentioned effect of separating the current tooth groove of the latching tooth 31 and the latching groove bar 34, and then adjust the position of the limit plate assembly 2 by translation.

[0035] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
