Description

Technical Field

[0001] This utility model relates to the field of steel pipe clamping technology, specifically a workpiece placement rack. Background Technology

[0002] In the steel pipe inspection process, it is often necessary to reliably and stably place and fix the steel pipes. Traditional steel pipe clamps come in various forms, but they generally have some shortcomings:

[0003] Manual operation is complex: Many clamps require operators to manually tighten bolts, turn levers, or adjust jaws to perform clamping and loosening actions. This is not only inefficient and increases labor intensity, but is also particularly inconvenient in situations requiring frequent clamping.

[0004] Reliance on external power: Some automated clamps use hydraulic, pneumatic, or electric drives to achieve clamping. While reducing the workload of manual labor, these clamps require an additional power source and a complex control system, resulting in a significant increase in equipment costs, relatively complex maintenance, and inability to be used in situations without a power supply. Utility Model Content

[0005] The purpose of this utility model is to provide a workpiece placement rack that solves the problem of cumbersome steel pipe placement and clamping processes in existing systems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a workpiece placement rack, including a base plate and two sets of support assemblies mounted on the base plate. The two sets of support assemblies are used to support steel pipes. Each support assembly includes a frame, a rotating rod, and a vertical rod. Rotating rods are rotatably mounted on both sides of the frame, and a vertical rod is slidably mounted in the middle of the frame. The vertical rod is connected to two rotating rods through two connecting rods respectively. The vertical rod, connecting rods, and rotating rods form a linkage structure.

[0008] Preferably, the bottom end of the support frame is provided with two bases, and the bases are fixedly connected to the base plate by bolts.

[0009] Preferably, the upright frame and the rotating rod are rotatably connected by a pin.

[0010] Preferably, a roller is mounted on the top end of the rotating rod.

[0011] Preferably, an mounting block is installed in the middle of the upright, and a sliding groove is formed between the mounting block and the upright, and the upright moves along the sliding groove.

[0012] Preferably, a mounting base is fixedly installed at the top of the upright, and two rollers are installed at the top of the mounting base.

[0013] Preferably, the telescopic component includes a guide rod, a spring, and a corner bracket. The corner bracket is mounted on the surface of the mounting block. The upper end of the guide rod is fixedly connected to the mounting bracket, and the lower end of the guide rod passes through the guide hole of the corner bracket. A spring is sleeved on the guide rod, and the spring is located above the corner bracket.

[0014] This utility model has the following beneficial effects:

[0015] (1) The end of the steel pipe of this utility model is placed at the end of the upright. Under the action of gravity, the upright is pushed to slide down. The downward sliding upright pushes the angle between the two connecting rods to increase, so that the connecting rod tends to be horizontal, pushing the bottom of the two rotating rods to rotate outward, thereby making the top of the two rotating rods approach each other and completing the rapid fixing of the placed steel pipe.

[0016] (2) The present invention uses two rollers on the mounting base and rollers on the rotating rods at both ends to support the steel pipe. When placed, the steel pipe can be manually rotated to facilitate inspection of the steel pipe surface.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 As shown, this utility model is a workpiece placement rack, including a base plate 2 and two sets of support assemblies 1 installed on the base plate 2. The two sets of support assemblies 1 are used to support steel pipes. The support assembly 1 includes a frame 11, a rotating rod 12 and a pole 16. The rotating rod 12 is rotatably installed on both sides of the frame 11, and the pole 16 is slidably installed in the middle of the frame 11. The pole 16 is connected to the two rotating rods 12 through two connecting rods 14 respectively. The pole 16, the connecting rods 14 and the rotating rod 12 constitute a linkage structure.

[0030] When clamping the steel pipe 3, the steel pipe 3 is placed on at least two support assemblies 1. During the placement process, the rotating rod 12 provided is moved towards the steel pipe 3 under the action of gravity to complete the clamping of the rotating rod 12 of the steel pipe 3.

[0031] After the inspection is completed, during the lifting process, once the upright 16 is no longer affected by gravity, the rotating rod 12 loosens, making it easier to quickly remove the steel pipe 3.

[0032] The end of the steel pipe 3 is placed at the end of the upright 16. Under the action of gravity, the upright 16 is pushed to slide downward. The downward sliding upright 16 pushes the included angle between the two connected rods 14 to increase, so that the connected rods 14 tend to be horizontal until the connected rods 14 are in a horizontal state.

[0033] When the steel pipe is placed, the weight of the steel pipe acts on the upright 16, pushing the upright 16 to slide downward. The downward sliding upright 16, through two connecting rods 14, pushes the bottom ends of the two rotating rods 12 to rotate outward around the pin axis, thereby causing the top ends of the two rotating rods 12 to move closer to each other inward (i.e. towards the steel pipe), ultimately achieving the clamping and fixing of the steel pipe.

[0034] The bottom of the support frame 11 is provided with two bases 111, and the bases 111 are fixedly connected to the base plate 2 by bolts;

[0035] The two sets of bracket assemblies 1 are respectively installed on two base plates 2, or the two sets of bracket assemblies 1 are installed on the same base plate 2;

[0036] like Figure 6 As shown, when supporting the long steel pipe 3 according to usage requirements, the bracket assembly 1 is fixed on the split base plate 2. By increasing the number of bracket assemblies 1, the long steel pipe 3 can be supported.

[0037] The upright frame 11 and the rotating rod 12 are connected by a pin, and the rotating rod 12 rotates around the pin axis after installation.

[0038] A roller 13 is mounted on the top of the rotating rod 12.

[0039] An installation block 15 is installed in the middle of the upright 11, and a groove is formed between the installation block 15 and the upright 11, and the upright 16 moves along the groove.

[0040] A mounting base 17 is fixedly installed at the top of the upright 16, and two rollers 18 are installed at the top of the mounting base 17.

[0041] The steel pipe 3 is supported by two rollers 18 provided on the mounting base 17, and the steel pipe 3 falls between the two rollers 18, which support the ends of the rollers 18.

[0042] In addition, the roller 13 and the roller 18 form a clamping end. After clamping is completed by the clamping end, the clamped steel pipe 3 can rotate, which makes it easy to observe the outer surface of the clamped steel pipe 3.

[0043] A telescopic component 19 is provided below the mounting base 17;

[0044] The telescopic component 19 includes a guide rod 191, a spring 192, and a corner seat 193. The corner seat 193 is mounted on the surface of the mounting block 15. The upper end of the guide rod 191 is fixedly connected to the mounting base 17. The lower end of the guide rod 191 passes through the guide hole of the corner seat 193. The spring 192 is sleeved on the guide rod 191 and is located above the corner seat 193.

[0045] The problem of the upright pole 16 being unable to return to its original position after compression is solved by installing the telescopic component 19.

[0046] When the steel pipe 3 is removed, the downward pressure on the steel pipe 3 disappears, and the spring 192 releases its elastic force to push the mounting base 17 and the upright 16 to move upward, which facilitates the upright 16 to drive the connecting rod 14 to reset. At the same time, the bottom end of the guide rod 191 is provided with external thread and is fitted with a nut. The nut is used to limit the movement and prevent the bottom end of the guide rod 191 from sliding out of the guide hole of the corner seat 193.

[0047] During the placement of the steel pipe 3, the mounting base 17 compresses the installed spring 192 under the action of gravity until the bottom end of the mounting base 17 contacts the surface of the mounting block 15.

[0048] The support frame 11, rotating rod 12, connecting rod 14 and upright pole 16 are all made of steel. The support frame 11, rotating rod 12, connecting rod 14 and upright pole 16 can be made of metal rods with an I-shaped cross-section, which can reduce the wall thickness of the metal rods, thereby reducing the weight of the support assembly 1 and reducing the amount of material used.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
