[0002] At present, with the rapid development of high-speed railways, the demand for H-shaped steel columns is increasing. H-shaped steel columns are important structural components of high-speed railways and are the carriers of power lines on both sides of the railway lines. H-shaped steel columns are sprayed with a protective layer on the surface, such as paint, before leaving the factory. During transportation or lifting, the protective layer is easily scratched or even seriously damaged by bumps. At present, there are mostly no special brackets for the transportation of H-shaped steel columns. They are often directly stacked or simply protected by cardboard, which cannot protect the H-shaped steel columns well. Moreover, with the existing transportation and loading methods, each H-shaped steel column is not fully positioned, and it is easy to move back and forth or swing, affecting the safety of vehicle transportation.

[0032] Embodiment 1:

[0033] In a specific embodiment, Figures 1 to 5 As shown, an H-steel column transport combination bracket includes a lower bracket 1, a middle bracket 2, an upper bracket 3, a locking mechanism and a press-fit assembly. The main structures of the lower bracket 1, the middle bracket 2 and the upper bracket 3 are consistent, including a crossbeam and vertical columns symmetrically welded and connected to the two ends of the crossbeam. A base plate 101 for support is welded to the bottom of the column of the lower bracket 1, and a lifting ring 301 is provided on the top of the column of the upper bracket 3 for easy connection of the sling. The lower bracket 1, the middle bracket 2 and the upper bracket 3 are stacked together from bottom to top and are quickly disassembled and assembled at the connection point through the locking mechanism. The press-fit assembly presses multiple H steel columns 19 placed in parallel on the crossbeam at intervals.

[0034] By stacking the lower bracket 1, the middle bracket 2 and the upper bracket 3, multiple H-steel columns 19 can be placed on each bracket crossbeam, and stacking them together facilitates overall lifting. When layers need to be taken, the locking mechanism can be disassembled to lift a layer of H-steel columns 19 individually or transfer them by forklift. The multiple H-steel columns 19 placed in parallel on the crossbeam are compressed at intervals by the press-fit assembly to ensure that the adjacent H-steel columns 19 above, below, left and right do not collide or contact. The H-steel column transfer combination bracket of the present invention can fix each H-shaped steel column in place during transportation and transfer, and there is no contact or collision between them, which reduces the risk of scratching and improves safety during transportation.

[0035] Specifically, the number of the middle brackets 2 is more than two, and the more than two middle brackets 2 are connected and stacked between the lower bracket 1 and the upper bracket 3 through the locking mechanism.

[0036] By adding the middle bracket 2, the number of loading layers can be increased, and the loading capacity can be expanded more conveniently.

[0037] In a specific embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the locking mechanism includes a lower clamping member 4, an upper mounting member 5, a bottom cover 6 and a bolt shaft 7. The lower clamping member 4 is coaxially fixedly connected to the top of the column, and a long hole 402 is provided in the middle of the lower clamping member 4. The cross section of the long hole 402 is larger than the block head 702 at the bottom end of the bolt shaft 7. The block head 702 can be inserted into the long hole 402 and is rotated and clamped on the bottom surface of the lower clamping member 4. The upper mounting member 5 is coaxially welded to the bottom end of the column, and the bottom cover 6 is assembled on the bottom opening of the upper mounting member 5 by bolts. The bolt shaft 7 can be rotatably clamped in the middle hole of the upper mounting member 5 and the bottom cover 6. The outer wall of the bolt shaft 7 is fixed with a toggle handle 701 that is extended outward, and the toggle handle 701 slides circumferentially on the slideway 401 at the top of the lower clamping member 4. The upper mounting member 5 is correspondingly provided with a long groove within the sliding range of the toggle handle 701.

[0038] Obviously, the locking mechanism can also be connected by a pin, and the pin is tied to the outer wall of the top of the column by an iron chain to prevent loss. Similar structural deformation methods all fall within the protection scope of the present invention.

[0039] Specifically, if Figure 3 and Figure 4 As shown, the locking mechanism also includes a locking lever 703, the root of which is connected to the outer end of the toggle handle 701 through a horizontal pin. The slideway 401 is a slideway opened at 90 degrees in the circumferential direction and a sinking groove is provided at the bottom side of the locking end, and the main body of the locking lever 703 can fall into the sinking groove.

[0040] The locking mechanism of the locking tongue structure can be connected and disassembled quickly and conveniently, and the connection strength is high and it is not easy to fall off. By arranging the locking lever 703 at the root of the locking lever 703, the locking lever 703 falls into the sinking groove in the locking position, which can avoid the release and unlocking caused by accidental collision in the locked state, and has good safety.

[0041] In a specific embodiment, Figure 1 , Figure 2 and Figure 5As shown, the press-fit assembly includes a clamping plate 11, a support member 12, a first screw 13 and a lock nut 14. The support member 12 is arranged on the crossbeam and located on both sides of the H steel column 19. The support member 12 is spaced apart from adjacent H steel columns 19, and multiple H steel columns 19 are arranged vertically. The first screw 13 vertically passes through the bottom end of the center hole of the support member 12 and is connected to the welded lock nut 18 on the crossbeam. The clamping plate 11 is provided with a through hole through which the first screw 13 passes and is pressed against the top surface of the H steel column 19 by the lock nut 14.

[0042] Specifically, if Figure 1 , Figure 2 and Figure 5 As shown, the press-fit assembly also includes a bottom pad 8, a spacer block 9 and a top pad 10. The bottom pad 8 is laid on the top surface of the beam. The width of the spacer block 9 is greater than the end plate of the support member 12 and spaces the H-steel column 19. The top pad 10 is pressed between the H-steel column 19 and the pressing plate 11.

[0043] Specifically, if Figure 1 , Figure 2 and Figure 5 As shown, the bottom pad 8 and the top pad 10 are specifically made of rubber plates, and the spacer block 9 is specifically made of composite resin blocks or wooden boards.

[0044] By tightening the clamping plate 11 with the first screw 13, the H-steel column 19 can be firmly fixed to prevent it from moving and swinging left and right. By setting the bottom pad 8, the spacer block 9 and the top pad 10 made of flexible material, all contact positions of the H-steel column 19 can be effectively protected to prevent hard contact from causing damage to the surface protective layer. When the H-steel column 19 is arranged vertically, the spacer block 9 passing through the first screw 13 isolates the contact on the left and right sides of the wing plate of the adjacent H-steel column 19, which can effectively prevent the adjacent H-steel columns from colliding with each other.

[0045] The loading process of the H-steel column transport combination bracket of Example 1 of the present invention is as follows: first, the two lower brackets 1 are arranged on the workshop floor according to the set spacing, and the overhead crane hoists the H-steel column 19 to the two lower bracket 1 crossbeams. Note that multiple H-steel columns 19 are arranged in parallel with equal spacing and the welding lock nut 18 is located on both sides of the H-steel column 19. Place the spacer block 9 to be sleeved on the welding lock nut 18 and located on both sides of the H-steel column 19. The bottom end of the first screw 13 is threadedly connected to the welding lock nut 18, and the support member 12 is connected to the first screw 13. The spacer block 9 is placed on the support member 12, the top pad 10 is laid, the clamping plate 11 is placed and locked with the lock nut 14 to complete the installation of the press-fit assembly. The middle bracket 2 is hoisted and stacked on top of the lower bracket 1, the toggle handle 701 is pulled to the position of the sinking groove and the locking lever 703 is dropped into the sinking groove to complete the locking of the middle bracket 2, and the H-steel column 19 is hoisted to the crossbeam of the middle bracket 2. The press-fit assembly of this layer is completed according to the installation method of the press-fit assembly of the lower bracket 1. Hoist the upper bracket 3 and stack it on top of the middle bracket 2, pull the toggle handle 701 to the sinking groove position and drop the locking lever 703 into the sinking groove to complete the locking of the upper bracket 3, hoist the H steel column 19 onto the crossbeam of the upper bracket 3, and complete the press-fitting of this layer in accordance with the installation method of the press-fit assembly of the lower bracket 1. The top lifting rings 301 of the two upper brackets 3 can be used for overall hoisting and loading. During the unloading process of the H steel column transport combination bracket of Example 1 of the present invention, the disassembly of the locking mechanism can enable flexible layered unloading and transportation.

[0046] Embodiment 2:

[0047] When the H steel column 19 is horizontally arranged, the press-fit assembly is modified on the basis of the first embodiment to form the present embodiment. Figure 6 and Figure 7 As shown, the press-fit assembly includes an inner positioning block 15, a second screw 16 and a clamping channel steel 17. The inner positioning blocks 15 are arranged on the crossbeam at equal intervals. The inner positioning blocks 15 are in the shape of rectangular convex blocks and their length is consistent with the web height of the H steel column 19. The top of the inner positioning block 15 is chamfered, and multiple H steel columns 19 are arranged horizontally. The clamping channel steel 17 is connected to the top of the crossbeam through multiple second screws 16 and clamps the upper edge of the wing plate of the H steel column 19. The second screws 16 are arranged at intervals on both sides of the H steel column 19.

[0048] Specifically, if Figure 6 and Figure 7 As shown, the press-fit assembly also includes a bottom pad 8, which is bonded and laid on the top surface of the beam, and a flexible pad is bonded and compounded on the bottom surface of the compression channel steel 17. The inner positioning block 15 includes a U-shaped bone plate 151 and a sleeve pad 152 sleeved on the outside of the U-shaped bone plate 151. The U-shaped bone plate 151 is welded to the top surface of the beam with its opening facing both ends.

[0049] The inner positioning blocks 15 are arranged at equal intervals on the crossbeam. When the H steel column 19 is placed on the crossbeam, the inner positioning blocks 15 can be clamped between the two wing plates of the horizontally placed H steel column 19, thereby positioning the H steel column 19 along the direction of the crossbeam to avoid the swing and collision of the H steel column 19. By setting the bottom pad 8 and the bottom surface of the compression channel steel 17 with a flexible pad layer and a sleeve pad 152, all contact positions of the H steel column 19 can be effectively protected to avoid damage to the surface protective layer caused by hard contact.

[0050] The loading process of the H-steel column transport assembly bracket of Example 2 of the present invention: The difference from Example 1 is that the H-steel column 19 is placed horizontally. When the H-steel column 19 is hoisted onto the crossbeam, the two wing plates of the H-steel column 19 are clamped onto the inner positioning block 15, and the positioning is more accurate. The bottom end of the second screw 16 is connected to the welding lock nut 18, and the top clamping channel steel 17 is placed above the H-steel column 19 with the opening facing upward, and is locked with a lock nut.

[0051] The present invention also discloses a working method of an I-beam beveling device, which utilizes the H-steel column transfer combined bracket described in any of the above embodiments to perform transfer and transportation operations of the H-steel column, adopts a layered stacking assembly method, and adjacent H-steel columns are completely positioned and do not collide with each other.

[0052] The H-steel column transport combination bracket of the present invention can place multiple H-steel columns 19 on each bracket crossbeam through the stacking of the lower bracket 1, the middle bracket 2 and the upper bracket 3. When stacked together, it is convenient for overall lifting. When it is necessary to take out in layers, the locking mechanism can be disassembled to lift a layer of H-steel columns 19 individually or transfer them by forklift. The multiple H-steel columns 19 placed in parallel on the crossbeam are compressed at intervals by the press-fit assembly to ensure that the adjacent H-steel columns 19 above, below, left and right do not collide or contact. The H-steel column transport combination bracket of the present invention can fix each H-shaped steel column in place during transportation and transfer, and there is no contact or collision between them, which reduces the risk of scratching and improves safety during transportation. In addition, by adding the middle bracket 2, the number of loading layers can be increased, and the loading capacity can be expanded more conveniently. The locking mechanism of the lock tongue structure can be conveniently and quickly connected and disassembled, and the connection strength is high and it is not easy to fall off. By arranging a locking lever 703 at the root of the locking lever 703, the locking lever 703 falls into the sinking groove in the locking position, which can avoid the release and unlocking caused by accidental collision in the locked state, and has good safety. By tightening the clamping plate 11 by the first screw 13, the H-steel column 19 can be firmly held and fixed to prevent it from moving and swinging left and right. By setting the bottom pad 8, the spacer block 9 and the top pad 10 made of flexible material, all contact positions of the H-steel column 19 can be effectively protected to avoid damage to the surface protective layer caused by hard contact. When the H-steel column 19 is arranged vertically, the spacer block 9 passing through the first screw 13 performs contact isolation on the left and right sides of the wing plate of the adjacent H-steel column 19, which can effectively prevent the adjacent H-steel columns from colliding with each other. The inner positioning blocks 15 are arranged at equal intervals on the crossbeam. When the H steel column 19 is placed on the crossbeam, the inner positioning blocks 15 can be clamped between the two wing plates of the horizontally placed H steel column 19, thereby positioning the H steel column 19 along the direction of the crossbeam to avoid the swing and collision of the H steel column 19. By setting the bottom pad 8 and the bottom surface of the compression channel steel 17 with a flexible pad layer and a sleeve pad 152, all contact positions of the H steel column 19 can be effectively protected to avoid damage to the surface protective layer caused by hard contact.

[0053] The working method of the I-beam beveling device of the present invention adopts a working mode of first positioning and then cutting both sides simultaneously, which greatly improves the production efficiency and the beveling quality.

[0054] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
