Description

Technical Field

[0001] This utility model relates to the field of flipping tire frame technology, specifically to a steel structure flipping tire frame. Background Technology

[0002] The existing steel structure flipping frame involves personnel lifting the H-beam above their chest or head and placing it on the flipping frame. The personnel then use the fixing mechanism on the flipping frame to fix the H-beam, and then drive the rotating component on the flipping frame to flip the H-beam, thus facilitating welding work on the H-beam.

[0003] While the above method allows H-beams to be placed on the flipping rack, it requires extremely high physical strength from the operators, especially when the H-beams are large, which can easily lead to muscle strain or sudden slippage accidents. Utility Model Content

[0004] In view of this, the present invention provides a steel structure flipping frame, which can avoid the need for personnel to lift the H-beam to their chest level, thus indirectly wasting a lot of the workers' physical strength.

[0005] To solve the above-mentioned technical problems, this utility model provides a steel structure tilting frame, including an H-support base. A lifting assembly is provided on the H-support base. The lifting assembly includes a first roller screw and a second roller screw respectively set at both ends of the H-support base. A first support frame is provided on the first roller screw, and a second support frame is provided on the second roller screw. A first support bar is provided on the first support frame, and a second support bar is provided on the second support frame. A rotating frame is installed on the first and second support bars via a rotating shaft. A sliding groove is provided on the side wall of each rotating frame, and a clamping plate is slidably installed inside the sliding groove. That is, the lifting assembly firstly drives the first and second support frames to move downward along the vertical guide rail through the synchronous rotation of the first and second roller screws. When the support frame descends to the preset low position, it is convenient for personnel to place the H-beam between the rotating frames. Then, the clamps move on the rotating frames to clamp the H-beam. Finally, the support frames one and two move upward along the vertical guide rail, and the personnel operate the rotating frames to rotate, which can cause the H-beam to flip over, making it convenient for personnel to perform subsequent welding processing on the H-beam.

[0006] The lifting assembly also includes a strip-shaped groove on the H-support base, in which a drive rod is rotatably mounted. Both the first and second lead rollers are equipped with bevel gear disks at their tail ends. The drive rod has two bevel gears that mesh with the bevel gear disks. In other words, the drive rod can drive the two bevel gears to rotate, thereby causing the bevel gear disks at the tail ends of the first and second lead rollers to rotate.

[0007] The lifting assembly also includes threaded rods that are all mounted on the side walls of the rotating frame. The first end of the threaded rod is connected to the side end of the clamping plate; that is, the threaded rod can drive the clamping plate to move.

[0008] The lifting assembly also includes two bearing seats, each mounted on the support crossbar, with a worm gear rotatably mounted between the two bearing seats. A worm wheel is mounted on the side end of the support crossbar, with one side of the worm wheel connected to one end of the rotating shaft. The worm wheel and the worm gear are meshed together; that is, the worm gear and the worm wheel have a self-locking function, so that when the worm gear rotates, it can drive the worm wheel to rotate.

[0009] The H-support base is equipped with a drive button one on its side, which is connected to one end of the drive rod. The rotating frame is equipped with a drive button two on its side, which is connected to the tail end of the threaded rod. The worm gear is equipped with a drive button three at its head. That is, drive button one, drive button two, and drive button three are used to provide rotation for the drive rod, the threaded rod, and the worm gear, respectively.

[0010] On both sides of the H-support base, there is a set of sliding columns one and a set of sliding columns two. Roller screw one is located between the set of sliding columns one, and roller screw two is located between the set of sliding columns two. The set of sliding columns one and the set of sliding columns two pass through the interior of the support frame one and the support frame two, respectively. That is, the set of sliding columns one and the set of sliding columns two are used to provide stability for the support frame one and the support frame two during the movement process.

[0011] The bottom of the H-support base is equipped with multiple self-locking casters; that is, the casters can move the H-support base.

[0012] The H-support base has a gantry frame one and a gantry frame two at its two ends. The bottom of the gantry frame one is connected to the head end of the first roller screw and the first set of sliding columns, respectively. The bottom of the gantry frame two is connected to the head end of the second roller screw and the second set of sliding columns, respectively. That is, the gantry frame one and the gantry frame two provide stability for the first roller screw, the first set of sliding columns, the second roller screw, and the second set of sliding columns.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By driving a pair of drive rods through the drive button, the two bevel gears mesh with the bevel gear disc, thereby driving the first and second roller screws to rotate simultaneously. This facilitates the lifting and lowering of the rotating frames on the first and second support blocks, thus avoiding the need for personnel to lift the H-beam to their chest level, indirectly wasting a lot of the workers' physical strength.

[0014] 2. By rotating the threaded rod through the second drive button, it can move forward on the rotating frame, thereby moving the clamping plate and clamping the H-beam, making it easier for personnel to operate. Attached Figure Description

Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] like Figure 1-5As shown: This embodiment provides a steel structure tilting frame, including an H-support base 100. A lifting assembly is provided on the H-support base 100. The lifting assembly includes a first roller screw 200 and a second roller screw 201 respectively disposed at both ends of the H-support base 100. The first roller screw 200 and the second roller screw 201 are mounted on the H-support base 100 via bearings. A first support frame 202 is provided on the first roller screw 200, and a second support frame 203 is provided on each of the second roller screws 201. The first roller screw 200 and the second roller screw 201 in the lifting assembly can respectively drive the first support frame 202 and the second support frame 203 to move up or down. A first support crossbar 204 is provided on the first support frame 202, and a second support crossbar 206 is provided on the second support frame 203. Supporting crossbar 206 and supporting crossbar 1 204 are fixedly installed on supporting frame 1 202 and supporting frame 203 by welding. Supporting frame 1 202 and supporting frame 203 provide support for supporting crossbar 206 and supporting crossbar 1 204 respectively. Rotating frame 211 is installed on supporting crossbar 1 204 and supporting crossbar 206 via rotating shaft. Each rotating frame 211 has a sliding groove 208 on its side wall. Each sliding groove 208 has a clamping plate 207 slidingly installed inside. The H-beam in the steel structure is placed in the middle of the rotating frame 211. The clamping plate 207 moves in the sliding groove 208 on the rotating frame 211, thereby limiting the H-beam. The rotating frame 211 carries the H-beam to the other side, which facilitates the flipping and welding of the steel structure. First, personnel use the first and second roller screws 200 and 201 in the lifting assembly to move the first and second support frames 202 and 203 downwards. This allows personnel to easily move the H-beam between the rotating frames 211, avoiding the need for personnel to lift the H-beam to their chest level, thus saving a significant amount of their energy. Then, the clamping plate 207 moves within the slide groove 208 to hold the H-beam. The lifting assembly then rotates again, causing the first and second support frames 202 and 203 to move the H-beam on the rotating frame 211 upwards. The rotation of the rotating frame 211 then causes the H-beam to rotate, facilitating subsequent processing of the H-beam.

[0018] H-support base 100 Figure 2 As shown, The lifting assembly also includes a strip-shaped groove 205 disposed on the H-support base 100. A drive rod 214 is rotatably disposed within the strip-shaped groove 205. The drive rod 214 is mounted on the strip-shaped groove 205 via bearings. A bevel gear disk 212 is disposed at the tail end of both the first roller screw 200 and the second roller screw 201. The bevel gear disk 212 is fixedly mounted on the first roller screw 200 and the second roller screw 201 by welding. Meanwhile, the first roller screw 200 and the second roller screw 201 are located inside the strip-shaped groove 205. Two bevel gears 213 are disposed on the drive rod 214. The two bevel gears 213 are fixedly mounted on the drive rod 214 and mesh with the bevel gear disk 212. First, the drive rod 214 drives the bevel gear 213 to rotate, thereby causing the two bevel gears 213 to mesh with the bevel gear disk 212. This allows the first roller screw 200 and the second roller screw 201 to be driven to rotate simultaneously, which facilitates the lifting and lowering of the first support frame 202 and the rotating frame 211 on the second support block. This avoids the need for personnel to lift the H-beam to their chest level, indirectly wasting a lot of the workers' physical strength.

[0019] Rotating frame 211 Figure 1 As shown, The lifting assembly also includes threaded rods 209 that are all set on the side wall of the rotating frame 211. The first end of the threaded rod 209 is connected to the side end of the clamping plate 207. The rotation of the threaded rod 209 can move forward on the rotating frame 211, thereby driving the clamping plate 207 to move, so as to clamp the H steel. Support bar 1204 Figure 1 As shown, The lifting assembly also includes two bearing seats, each mounted on a support crossbar 204. A worm gear 210 is rotatably mounted between the two bearing seats. A worm wheel 215 is mounted on the side end of the support crossbar 204. One side of the worm wheel 215 is connected to one end of the rotating shaft. The worm wheel 215 meshes with the worm gear 210. The worm gear 210 and the worm wheel 215 have a self-locking function. Thus, by driving the worm gear 210, the worm wheel 215 can be rotated, which indirectly drives the rotating shaft to rotate, thereby causing the rotating frame 211 to flip. Drive button 106 Figure 2 As shown, The H support base 100 is provided with a drive button 106 on its side end. The drive button 106 is connected to one end of the drive rod 214.
