Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and in particular to a steel pipe fixing support device for steel pipe processing. Background Technology

[0002] Steel pipes are hollow steel materials whose length is much greater than their diameter or circumference. They are classified by material into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes, and composite steel pipes. During processing, steel pipes need to be fixed and supported by a steel pipe fixing support device to prevent the steel pipes from shifting during processing.

[0003] A search revealed, for example, a utility model with publication number CN221560345U, which discloses a steel pipe fixing support device for steel pipe processing. This device includes a base plate with a first groove on its upper side. A motor is fixedly connected to the right side of the base plate, and a bidirectional threaded rod is fixedly connected to the output end of the motor. This utility model achieves clamping and fixing of the steel pipe through the coordinated use of a hydraulic rod, a moving block, a second groove, a support block, a spring, a fixing block, and an upper clamp. However, this utility model fixes the steel pipe by clamping its outer surface. In steel pipe processing, different positions of the steel pipe often need to be processed, and the clamping and fixing method of this utility model is relatively simple, making it inconvenient to meet the clamping and fixing needs when processing different positions of the steel pipe. Therefore, to solve the above defects, the inventor proposes a steel pipe fixing support device for steel pipe processing. Utility Model Content

[0016] This utility model discloses a steel pipe fixing support device for steel pipe processing. By setting a fixed platform, in actual operation, a first motor drives a bidirectional threaded rod to rotate, causing two second sliders to move two fixed plates in opposite directions.

This allows for switching between two clamping and fixing methods: internal support clamping and external wall clamping. This enriches the clamping and fixing methods, facilitating the clamping and fixing needs during processing of steel pipes at different positions. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This utility model discloses a steel pipe fixing support device for steel pipe processing, such as... Figure 1-5As shown, it includes a base 1 and a fixed platform 2 on the top surface of the base 1. The upper and lower sides of the fixed platform 2 are fixedly installed with first slide rails 201, and the outer surfaces of the two first slide rails 201 are slidably connected with first sliders 202. The first sliders 202 can move along the first slide rails 201.

[0025] Each of the two first sliders 202 has a support block 208 fixedly installed at one end extending outside the fixed platform 2. When the two first sliders 202 move, they will drive the two support blocks 208 to move, so as to adjust the position of the two support blocks 208.

[0026] The fixed platform 2 has two second slide rails 203 fixedly installed on the left and right sides inside, and the outer surfaces of the two second slide rails 203 are slidably connected to the second sliders 204, which can move along the second slide rails 203.

[0027] Two second sliders 204 are fixedly mounted with a fixing plate 207 at one end extending outside the fixing platform 2, and an inner support cylinder 210 for fixing the steel pipe is fixedly mounted on the opposite side of the two fixing plates 207. When the second sliders 204 move, they will drive the fixing plate 207 and the inner support cylinder 210 to move, so as to internally support and clamp the steel pipes of different lengths.

[0028] The fixed platform 2 is internally rotatably connected to a bidirectional threaded rod 211, and both second sliders 204 are threadedly connected to the bidirectional threaded rod 211. Two drive arms 205 are hinged to the left and right sides of the outer surface of the two first sliders 202, and the ends of the four drive arms 205 away from the first sliders 202 are respectively hinged to the two second sliders 204.

[0029] A first motor 206 is fixedly installed on one side of the outer surface of the fixed platform 2, and the output end of the first motor 206 is fixedly connected to the bidirectional threaded rod 211. The outer surface of the bidirectional threaded rod 211 is provided with two opposite threads. The first motor 206 drives the bidirectional threaded rod 211 to rotate, which can make the two second sliders 204 move in opposite directions. A support plate 2087 is fixedly installed in the middle of the outer top surface of the fixed platform 2. The steel pipe is placed on the support plate 2087, and the support plate 2087 can support the steel pipe.

[0030] When the two fixed plates 207 approach each other, the two drive arms 205 will push the two first sliders 202 and the two support blocks 208 away from each other. When the two second sliders 204 drive the two fixed plates 207 away from each other, the two support blocks 208 will approach each other.

[0031] Four movable rods 2101 are slidably connected to the outer surface of the inner support cylinder 210. Parts of the four movable rods 2101 are located inside the inner support cylinder 210, and the other parts of the four movable rods 2101 are located outside the inner support cylinder 210. An inner support plate 2102 is fixedly installed at one end of the four movable rods 2101 located outside the inner support cylinder 210. When the movable rods 2101 move, they will drive the inner support plates 2102 to move. The cross-sectional shape of the four inner support plates 2102 is arc-shaped so that they can better fit the inner wall of the cylindrical steel pipe.

[0032] Furthermore, each of the four movable rods 2101 is fixedly installed with a connecting rod 2103 on one side inside the inner support cylinder 210. The inner support cylinder 210 is rotatably connected to a drive plate 2104, and four drive holes 2105 are opened on one side of the drive plate 2104. The four connecting rods 2103 are movably connected to the four drive holes 2105 respectively.

[0033] A second motor 209 is fixedly installed on the side of each of the two fixed plates 207 away from the inner support cylinder 210. The output end of the second motor 209 is fixedly connected to the drive plate 2104. The second motor 209 drives the drive plate 2104 to rotate. When the drive plate 2104 rotates, the four movable rods 2101 can move simultaneously to fit the steel pipe onto the outer surface of the inner support cylinder 210. Then the drive plate 2104 rotates, and the four movable rods 2101 simultaneously push the four inner support plates 2102 to move until the four inner support plates 2102 contact the inner wall of the steel pipe to clamp the steel pipe.

[0034] Each of the two support blocks 208 has a movable groove 2081 on one side opposite to the other, and a slide rod 2082 is fixedly installed inside each of the two movable grooves 2081. Two moving blocks 2083 are slidably connected to the outer surfaces of the two slide rods 2082, and an outer clamping plate 2085 is fixedly installed on one side opposite to the other of the four moving blocks 2083. When the two support blocks 208 approach each other, the two outer clamping plates 2085 will clamp and fix the outer surface of the steel pipe placed on the support plate 2087.

[0035] The top surfaces of the four movable blocks 2083 are provided with positioning holes 2084, and the outer top surfaces of the two support blocks 208 are provided with multiple fixing holes 2086. The movable blocks 2083 can move along the slide rod 2082, thereby adjusting the position of the outer clamping plate 2085. When the movable blocks 2083 move, the positioning holes 2084 will coincide with the multiple fixing holes 2086 in sequence. By inserting bolts into the coincided positioning holes 2084 and fixing holes 2086, the moved movable blocks 2083 can be fixed.

[0036] Four telescopic rods 1101 are fixedly installed on the top surface of the base 1, and all four telescopic rods 1101 are fixedly connected to the outer bottom surface of the fixed platform 2. A cylinder 1102 is fixedly installed in the middle of the top surface of the base 1, and the output end of the cylinder 1102 is fixedly connected to the outer bottom surface of the fixed platform 2. The cylinder 1102 can push the fixed platform 2 to rise and fall, so as to adjust the height of the fixed platform 2 so that workers of different heights can process steel pipes. When the fixed platform 2 rises and falls, it will drive the four telescopic rods 1101 to extend and retract.

[0037] The working principle of this utility model is as follows: The steel pipe is placed on the top surface of the support plate 2087. When the outer surface of the steel pipe needs to be processed, the first motor 206 drives the bidirectional threaded rod 211 to rotate, so that the two second sliders 204 drive the two fixed plates 207 to move closer to each other until the two inner support cylinders 210 are inserted into the two ends of the steel pipe. Then the second motor 209 drives the drive plate 2104 to rotate, and the four movable rods 2101 simultaneously push the four inner support plates 2102 to move until the four inner support plates 2102 contact the inner wall of the steel pipe to clamp the inner support of the steel pipe. When the two ends and the inner wall of the steel pipe need to be processed, the first motor 206 drives the bidirectional threaded rod 211 to rotate, so that the two second sliders 204 move away from each other, so that the two first sliders 202 drive the two support blocks 208 to move closer to each other until the four outer clamping plates 2085 contact the outer surface of the steel pipe to clamp the outer wall of the steel pipe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
