Description

Technical Field

[0001] This invention belongs to the field of steel pipe processing, specifically a quick loading and unloading transfer frame for steel pipe processing. Background Technology

[0002] During steel pipe processing, the pipes are stacked in workshops and shipping areas, with non-metallic materials such as sleepers, sandbags, or straw mats used as a padding layer to prevent hard contact. For further processing or use, they are transported and retrieved using transfer equipment. Overhead cranes can be used for hoisting, but their installation requires a certain amount of space. While the crane's hoisting function can be used within its installation area, it's not suitable for other areas due to space limitations. When using forklifts or other transfer vehicles, the pipes need to be stacked on the transfer equipment's surface, and the equipment's movement controlled for transport. Because of the varying weights of the pipes, lighter ones can be handled manually, while heavier ones require overhead cranes or other hoisting equipment to move them to the transfer platform. This method of transfer increases the complexity and time required for loading and unloading, making manual handling more difficult.

[0003] In summary, the present invention provides a quick loading and unloading transfer frame for steel pipe processing to solve the above problems. Summary of the Invention

A hydraulic rod is installed on the surface of the movable base plate, with one end of the hydraulic rod fixedly connected to the middle of one of the push frames. Multiple symmetrically arranged casters are installed at the bottom of the movable base plate.

[0006] Furthermore, a locking block groove is provided on one side of the transfer platform near the flip-blocking rod, and an adjusting inner groove is provided at the bottom of the transfer platform. Two locking blocks are movably arranged in the locking block groove, and a push rod is vertically connected to one side of each locking block. The push rod passes through one side of the locking block groove and is inserted into the adjusting inner groove. A top block is fixedly connected to one end of the push rod inserted into the adjusting inner groove, and the top block is connected to one side of the inner wall of the adjusting inner groove by a spring.

[0007] Furthermore, a shrinkage cavity is provided on the side of the adjusting inner groove away from the locking block groove, and a limiting rod is fixedly connected to the side of the top block away from the push rod. One end of the limiting rod is movably inserted into the shrinkage cavity, and the spring is movably wound around the surface of the limiting rod.

[0008] Furthermore, the inner walls on both sides of the adjusting inner groove are respectively provided with track grooves, and a push plate is slidably connected in the adjusting inner groove. The two push rods are respectively movably installed through the push plate, and one side of the push plate is in contact with the surface of the top block.

[0009] Furthermore, an arc-shaped rotating block is fixedly connected to one end of the flip-up shielding rod. The arc-shaped rotating block is rotatably connected to one side of the transfer platform via a rotating shaft. A flat groove is provided on one side of the arc-shaped rotating block, and the flat groove is horizontally aligned along the axial direction of the flip-up shielding rod.

[0010] Furthermore, the push frame has a "U" shaped structure, and gear grooves are respectively opened on the two outer walls of the push frame near the opening. The gear grooves mesh with the teeth on the surface of the rotating gear. The hydraulic rod is fixedly connected to the inner wall of the push frame on the side away from the opening.

[0011] Furthermore, the surface of the push frame is provided with a sliding groove, and a limiting guide plate is slidably connected to the surface of the push frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this invention, the horizontal height of the transfer platform can be adjusted by using the lifting screw and adjustment mechanism between the transfer platform and the moving base. When the transfer platform moves to the bottom of the steel pipe, the upper steel pipe can be directly supported by adjusting the horizontal height of the transfer platform, eliminating the need to move the steel pipes to the surface of the transfer platform one by one. During unloading, the horizontal height of the transfer platform can still be changed to unload quickly in one go, achieving the purpose of rapid transfer.

[0015] 2. This invention sets up two push frames that move at the same frequency, controls the rotation of the adjusting cylinders on both sides, and thus realizes the simultaneous lifting and lowering of multiple lifting screws. The transfer platform can be raised and lowered horizontally, so that the steel pipe can maintain stability on the surface. The two push frames are connected by a linkage plate, and the movement of the two push frames can be controlled simultaneously by controlling one of the push frames with a hydraulic rod.

[0016] 3. This invention features a fixed limiting handrail on one side of the transfer platform, which allows the entire transfer frame to move. On the other side, a movable flip-up blocking rod is provided. By changing the angle of the flip-up blocking rod, the other side of the transfer platform can be blocked. During transfer, the flip-up blocking rod can be opened to block both sides of the steel pipe, preventing it from rolling off. During loading and unloading, by restoring the position of the flip-up blocking rod, the steel pipe can be quickly moved from one side of the transfer platform, achieving rapid loading and unloading.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] like Figure 1-6 As shown, this invention provides a quick loading and unloading transfer frame for steel pipe processing, including a transfer platform 1 and a parallel movable base plate 2. Multiple lifting screws 6 are fixedly connected to the bottom of the transfer platform 1. Two symmetrically arranged flip-over baffles 4 are rotatably connected to one side of the transfer platform 1. A limit handrail 3 is installed on the side of the transfer platform 1 away from the flip-over baffles 4. A locking mechanism 7 is provided on the side of the transfer platform 1 near the flip-over baffles 4. Four symmetrically arranged adjusting mechanisms 8 are installed on the surface of the movable base plate 2. Each adjusting mechanism 8 includes an adjusting cylinder 801 and a rotating gear 802. The adjusting cylinders 801 are respectively sleeved on the surface of the lifting screws 6. The rotating gear 802 is fixedly sleeved on the surface of the adjusting cylinder 801. A pusher 9 is provided between the two adjusting cylinders 801 on the same side of the transfer platform 1. The two pushers 9 are fixedly connected by a linkage plate 10. A hydraulic rod 11 is installed on the surface of the movable base plate 2. One end of the hydraulic rod 11 is fixedly connected to the middle of one of the pushers 9. Multiple mutually symmetrical moving wheels 5 are installed at the bottom of the movable base plate 2. The two pushers 9 are controlled by the hydraulic rod 11, thereby adjusting the adjusting mechanism 8. The lifting screw 6 can rise and fall on the surface of the adjusting mechanism 8, changing the horizontal height of the transfer platform 1, supporting or moving away from the steel pipe.

[0027] like Figure 2-3A locking block groove 701 is provided on one side of the transfer platform 1 near the flipping shield rod 4. An adjusting inner groove 702 is provided at the bottom of the transfer platform 1. Two locking blocks 703 are movably arranged in the locking block groove 701. A push rod 704 is vertically connected to one side of each locking block 703. The push rod 704 passes through one side of the locking block groove 701 and is inserted into the adjusting inner groove 702. A top block is fixedly connected to one end of the push rod 704 inserted into the adjusting inner groove 702. The top block is connected to the inner wall of one side of the adjusting inner groove 702 by a spring 706. The spring 706 supports the top block, and then the push rod 704 pushes the locking block 703 to move, and the locking block 703 moves in the locking block groove 701.

[0028] like Figure 2 A contraction cavity is provided on the side of the adjusting inner groove 702 away from the locking block groove 701. A limiting rod is fixedly connected to the side of the top block away from the push rod 704. One end of the limiting rod is movably inserted into the contraction cavity. A spring 706 is movably wound around the surface of the limiting rod. The spring 706 wound around the surface of the limiting rod can ensure that the spring 706 can always move in a straight line when contracting. The limiting rod slides in the contraction cavity. When the locking block 703 moves, it moves in the horizontal direction.

[0029] like Figure 2 , 3 The inner walls on both sides of the adjusting inner groove 702 are respectively provided with track grooves. A push plate 705 is slidably connected inside the adjusting inner groove 702. Two push rods 704 are respectively movably inserted through the push plate 705. One side of the push plate 705 contacts the surface of the top block. The push plate 705 can push the two top blocks to move. The push plate 705 is limited to sliding on the surface of the push rods 704. When one of the two top blocks moves, the push plate 705 can be pushed to move. The position of the push plate 705 can also adjust the position of the top block, thereby achieving the purpose of moving the position of the locking block 703. The two locking blocks 703 can move independently or can be moved simultaneously by the push plate 705.

[0030] like Figure 1 , 3 An arc-shaped rotating block is fixedly connected to one end of the flip-blocking rod 4. The arc-shaped rotating block is rotatably connected to one side of the transfer platform 1 via a rotating shaft. A flat groove is provided on one side of the arc-shaped rotating block. The flat groove is horizontally aligned along the axial direction of the flip-blocking rod 4. When the flip-blocking rod 4 rotates to be horizontally aligned with the transfer platform 1, the flat groove is also horizontally aligned with the surface of the transfer platform 1. When the flip-blocking rod 4 is perpendicular to the surface of the transfer platform 1, the flat groove also rotates at the same time. The locking block 703 moves to one side of the flat groove, and the locking block 703 can limit one end of the flip-blocking rod 4 to prevent the flip-blocking rod 4 from continuing to move.

[0031] like Figure 4The push frame 9 has a "U" shaped structure. Gear grooves are respectively opened on the outer walls of the push frame 9 near the opening. The gear grooves mesh with the teeth on the surface of the rotating gear 802. The hydraulic rod 11 is fixedly connected to the inner wall of the push frame 9 away from the opening. The gear groove meshes with the rotating gear 802. The gear groove can drive the rotating gear 802 to rotate, thereby realizing the rotation of the adjusting cylinder 801.

[0032] like Figure 3 , 4 The surface of the push frame 9 is provided with a sliding groove. A limiting guide plate 12 is slidably connected to the surface of the push frame 9. The limiting guide plate 12 is slidably locked on the side of the push frame 9 away from the gear groove and is slidably connected to the sliding groove. The limiting guide plate 12 is fixedly connected to the surface of the movable base plate 2. When the push frame 9 moves, it slides along the surface of the limiting guide plate 12. The push frame 9 is supported by the limiting guide plate 12 and slides on the surface of the movable base 2.

[0033] like Figure 4 The bottom of the adjusting cylinder 801 is rotatably connected to the surface of the movable base plate 2. A threaded adjusting groove is provided on the end of the adjusting cylinder 801 away from the movable base plate 2. The lifting screw 6 is provided in a one-to-one correspondence with the adjusting cylinder 801 and is connected to the adjusting cylinder 801 by a thread. When the adjusting cylinder 801 is driven to rotate by the rotating gear 802, the lifting screw 6 can be raised and lowered inside the adjusting cylinder 801 because it is connected to the adjusting cylinder 801 by a thread, thereby adjusting the horizontal height of the transfer platform 1.

[0034] Specific working principle:

[0035] like Figure 5 The flip-over shielding rod 4 is aligned horizontally with the transfer platform 1. The end near the flip-over shielding rod 4 is inserted into the bottom of the raised steel pipe. The hydraulic rod 11 is activated, which drives the two push frames 9 to move, causing the bottom rotating gear 802 to rotate. The four adjusting cylinders 801 rotate, and the lifting screw 6 rises and falls within the adjusting cylinders 801. When the lifting screw 6 rises, the transfer platform 1 rises and moves to the bottom of the steel pipe to support it, keeping the steel pipe away from the raised layer. Then, the movable base plate 2 can be pushed to move, changing the position of the steel pipe for transfer. When unloading, both ends of the steel pipe are moved to the upper end of the sleepers. The hydraulic rod 11 retracts, and the push frames 9 drive the adjusting cylinders 801 to rotate in the opposite direction. At the same time, the lifting screw 6 moves downward, and the steel pipe is supported by the sleepers. The movable base plate 2 moves out from one side of the flip-over shielding rod 4, completing the unloading operation.

[0036] like Figure 6During the transfer, when the flip-over blocking rod 4 is rotated and the flip-over blocking rod 4 is disposed with the transfer platform 1, the locking block 703 is supported by the spring 706 and then moves to one side of the flip-over blocking rod 4 to prevent the flip-over blocking rod 4 from rotating and limit the position of the flip-over blocking rod 4. This pushes the limit handrail 3 to move, and by pushing the push plate 705 inward, the push plate 705 pushes the top block to move. Then, the push rod 704 pulls the locking block 703 back into the locking block groove 701, and the flip-over blocking rod 4 loses its limiting function and returns to its original position. At this time, the locking block 703 is supported on one side of the flip-over blocking rod 4.

[0037] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
