[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0029] Please see Figure 1-6 This utility model provides an auxiliary tooling for flipping guard plate columns, including two supporting columns 2 and two limiting columns 4. The two supporting columns 2 and the two limiting columns 4 are connected in sequence by a connecting beam 6. The connecting beam 6 between the two supporting columns 2 is provided with a built-in lifting mechanism 11 in the middle. The two limiting columns 4 are provided with external lifting mechanisms 10 on their outer sides. The bottom of the built-in lifting mechanism 11 and the external lifting mechanism 10 are fixedly connected with casters 12. Limiting grooves 5 are symmetrically opened on the upper surface of the two limiting columns 4. The outer side of the limiting grooves 5 is provided with a detachable locking component.

[0030] In this embodiment, to address the technical problems of low efficiency in flipping the protective plate columns in existing technologies, and the potential for cracking or breakage at the bottom of the columns during the flipping process, thus posing safety hazards, this embodiment proposes an auxiliary tooling for flipping the protective plate columns. This tooling mainly comprises two supporting columns 2, two limiting columns 4, and a connecting beam 6. The two supporting columns 2 and the two limiting columns 4 are collinear, and are sequentially connected and fixed to each other by the connecting beam 6. The distance between the two limiting columns 4 is equal to the width of the protective plate column, and the distance between the two supporting columns 2 is less than or equal to the distance between the two limiting columns 4.

[0031] When the distance between the two supporting columns 2 is equal to the distance between the two limiting columns 4, the supporting columns 2 and the corresponding limiting columns 4 are connected and fixed by a connecting beam 6 to ensure the stability of the tooling.

[0032] When the distance between the two supporting columns 2 is less than the distance between the two limiting columns 4, in order to further increase the stability of the tooling, two connecting beams 6 are respectively set between the connecting beam 6 between the two limiting columns 4 and the two supporting columns 2, so that the three connecting beams 6 form a triangular structure.

[0033] During operation, the external lifting mechanism 10 is first activated, causing the casters 12 below it to extend downwards until the limit column 4 is one distance from the ground. Then, the internal lifting mechanism 11 is activated until the support column 2 is one distance from the ground. The tooling is then moved to the designated position, and the casters 12 of both the internal and external lifting mechanisms 11 are sequentially retracted upwards. Next, a truck crane or forklift is used to place the temporary rotating shaft installed on the guard plate column into the limit groove 5 on the tooling and lock it in place using the locking assembly. The column is then flipped. Throughout the process, the tooling is lightweight and easy to transport and move, allowing for rapid movement according to changes in the guard plate column's installation position. The truck crane can complete the flipping and installation of the guard plate column in one operation, reducing the number of lifting operations and improving the efficiency of flipping and installation. The guard plate column does not directly contact the ground or metal structures, eliminating the risk of impact damage during flipping.

[0034] In this embodiment, the top of each of the two supporting columns 2 is provided with a rubber pad 3. The rubber pad 3 can play a buffering and supporting role when the protective plate column is placed, so as to avoid the protective plate column colliding with the supporting column 2 and damaging the protective plate.

[0035] Both support columns 2 are fixedly connected to a base plate 1 at their bottom, and a rib plate 7 is provided between the base plate 1 and the support column 2. The base plate 1 increases the contact area between the support column 2 and the ground, thereby further increasing the stability of the tooling. At the same time, the rib plate 7 between the base plate 1 and the support column 2 increases the stability of the connection between the support column 2 and the base plate 1, preventing deformation.

[0036] In this embodiment, ribs 7 are fixedly connected to the opposite side of the two limiting columns 4 and the supporting column 2. A base plate 1 is fixedly connected to the bottom of both the limiting columns 4 and the ribs 7. The ribs 7 are enlarged and thickened to ensure the stability of the tooling during the flipping process of the guard plate column. This prevents the limiting columns 4 from being deformed by horizontal forces and the overall flipping auxiliary tooling from tilting up when the guard plate column is flipped.

[0037] In this embodiment, the limiting groove 5 is dovetail-shaped with a larger top and a smaller bottom, which can improve the efficiency of placing the guard plate column.

[0038] As a further description of the above embodiment, in order to ensure the stability of the temporary rotating shaft installed on the guard plate column within the limiting groove 5, and to ensure that the guard plate column does not shift when it is flipped, thus eliminating safety hazards, a limiting component is provided at the limiting groove 5. The limiting component is a latch 9. The latch 9 includes an arc-shaped buckle 91, and both ends of the arc-shaped buckle 91 are fixedly connected to fixing blocks 92. A pin hole is opened in the middle of the fixing block 92, and a pin 93 is provided in the pin hole.

[0039] Meanwhile, insertion holes are provided on the outer walls of the two limiting columns 4 at positions corresponding to the pins 93. After the temporary rotating shaft installed on the guard plate column is placed in the limiting groove 5, the buckle 91 is placed on the temporary rotating shaft, and then the two pins 93 are inserted into the insertion holes on the limiting columns 4 respectively.

[0040] As a further description of the above embodiment, a movable opening is provided in the middle of the connecting beam 6 between the two supporting columns 2. The built-in lifting mechanism 11 includes a lead screw 111, the bottom of which is connected to a caster wheel 12, the upper end of which passes through the movable opening, and two handle nuts 110 are threaded onto the lead screw 111. The two handle nuts 110 are respectively located on the upper and lower sides of the connecting beam 6.

[0041] During operation, when the tooling needs to be moved, first rotate the upper handle nut 110 upwards to the designated position, then rotate the lower handle nut 110 to move the connecting beam 6 and the support column 2 upwards until the lower base plate 1 of the support column 2 is off the ground. Conversely, when the tooling needs to be fixed, move the lower handle nut 110 downwards until the lower base plate 1 of the support column 2 contacts the ground.

[0042] In this embodiment, the handle nuts 110 are located on the upper and lower sides of the connecting beam 6, which can play a positioning role for the connecting beam 6, preventing the tooling from shaking during movement, thereby increasing the stability of the tooling during operation.

[0043] In this embodiment, the height of the lead screw 111 after it passes through the moving opening is lower than the height of the support column 2, thereby ensuring that the guard plate column can be placed stably on the support column 2.

[0044] As a further description of the above embodiments, the external lifting mechanism 10 includes a lifter 101 and a rocker arm 102, with the bottom of the lifter 101 fixedly connected to the caster wheel 12.

[0045] During operation, when the tooling needs to be moved, rotating the rocker arm 102 causes the lifting device 101 to extend the caster wheel 12 downwards until the base plate 1 of the limiting column 4 is off the ground. When the tooling needs to be fixed, rotating the rocker arm 102 in the opposite direction makes the base plate 1 of the limiting column 4 contact the ground.

[0046] In this embodiment, the lifting device 101 is a prior art. The specific structure of the lifting device 101 and the connection method between it and the rocker arm 102 are known to those skilled in the art based on the prior art, so it will not be described further.

[0047] As a further description of the above embodiment, in order to avoid direct contact and collision damage between the guard plate column and the connecting beam 6 during the process of the guard plate column being flipped to the upright state, in this embodiment, a plurality of anti-collision pads 8 are evenly provided on the connecting beam 6 between the two limiting columns 4 along the length direction of the connecting beam 6, and the anti-collision pads 8 are provided on the side opposite to the supporting column 2.

[0048] In summary, the working principle of the auxiliary tooling for flipping the guard plate column is as follows:

[0049] 1. Rotate the rocker arm 102 to control the lifting device 101 to drive the caster wheel 12 to extend downwards until the bottom plate 1 of the limit column 4 is lifted off the ground a certain distance away; first rotate the upper handle nut 110 upwards to the designated position, and then rotate the lower handle nut 110 to drive the connecting beam 6 and the support column 2 of this part to move upwards until the bottom plate 1 of the support column 2 is lifted off the ground a certain distance away. At this time, the upper and lower handle nuts 110 lock the connecting beam 6 of this part to prevent the tooling from shaking when it moves.

[0050] 2. The tool is moved manually to the designated position, and the casters 12 of the built-in lifting mechanism 11 and the external lifting mechanism 10 are retracted upwards in the reverse order of step 1.

[0051] 3. Use a truck crane, forklift, or similar equipment to place the flat guard plate column onto the auxiliary fixture. When placing it, ensure that the rotating shaft temporarily installed on the guard plate column is positioned exactly within the limiting groove 5 on the limiting column 4. Install the locking buckle 9 to secure the temporary rotating shaft installed on the guard plate column.

[0052] 4. Use a truck crane to lift the top of the guard plate column. Lift the top of the guard plate column upwards, and the guard plate column will rotate around the extension line of the rotation axis. When the guard plate column is rotated into an upright position, the bottom of the guard plate column will just contact the anti-collision pad 8, which can avoid the guard plate column from directly contacting the tooling and causing collision damage.

[0053] 5. Remove the locking buckle 9 and lift the guard plate column away from the flipping auxiliary tool for installation.

[0054] In summary, the truck crane in this invention can complete the flipping and installation of the guard plate column in one operation, reducing the number of lifting operations and improving the efficiency of flipping and installation. Simultaneously, the guard plate column does not directly contact the ground or metal structure during the flipping process, eliminating the risk of impact damage and improving safety. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
