Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a longitudinal steel pipe conveyor. Background Technology

[0002] The longitudinal direction of a steel pipe refers to its axial direction. A longitudinal steel pipe conveyor, also known as a linear steel pipe conveyor, is used to transport and move steel pipes along their length during processing. Chinese utility model patent CN222612271U discloses a longitudinal steel pipe conveyor, including a mounting frame. A fixed mounting platform is fixedly connected to one side of the upper surface of the mounting frame. An installation cavity is formed on the upper surface of the fixed mounting platform, and a threaded moving block is slidably connected inside the cavity. A power component for driving the threaded moving block is mounted on the fixed mounting platform. A connecting frame is fixedly connected to the upper surface of the threaded moving block, and an abutment component is installed on the side wall of the connecting frame. A fixed plate is fixedly connected to the other side of the upper surface of the mounting frame. This utility model activates multiple second drive cylinders. The piston end of the second drive cylinder moves a fixed rod, causing the fixed rod to move a second mounting plate closer to a first mounting plate, adjusting the distance between the first and second mounting plates. It is suitable for steel pipes of different diameters, effectively reducing pipe swaying and ensuring the stability of the steel pipe transport. However, the above solution also has the following shortcomings: the servo motor 5 drives the threaded rotating rod 6, which in turn drives the push plate 9 to move laterally, thereby pushing the steel pipe to move longitudinally. However, the length of the steel pipe is generally not less than five meters, so the threaded rotating rod 6 also needs to reach the corresponding length. However, slender screws (the length-to-diameter ratio of the screw is generally not more than 50) are difficult to process due to their poor rigidity, so the above solution cannot be implemented. Summary of the Invention

[0003] The purpose of this utility model is to provide a longitudinal steel pipe conveyor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a longitudinal steel pipe conveyor, comprising a rectangular mounting frame and a support frame. Multiple conveying rollers are equidistantly mounted on the mounting frame along its length. Adjacent conveying rollers are driven by a pulley system at their ends. A reduction motor is fixedly connected to the side of the mounting frame, driving the conveying rollers to rotate. Four symmetrical inserts are located at the bottom of the mounting frame, with the lower ends of the inserts corresponding to the legs of the support frame. A scissor-type lifting mechanism is mounted on the support frame, with its top connected to the mounting frame for height adjustment. Four symmetrical round rods are fixedly connected to the top of the mounting frame, with a top plate fixedly connected between the tops of the four round rods. A pressure plate is slidably connected between the four round rods, and a pressure roller is mounted on the lower side of the pressure plate. The pressure roller and the conveying rollers are on the same vertical plane.

[0005] Preferably, the pressure roller and the conveying roller have the same structural dimensions and the outer side is provided with a V-shaped annular groove along the circumference.

[0006] Preferably, a spring is sleeved on the round rod, and the spring applies downward pressure to the pressure plate.

[0007] Preferably, a vertical pull rod is fixedly connected to the upper end of the pressure plate. The pull rod passes through the middle of the top plate and is slidably connected to it. A tiltable and flip-up handle is hinged to the upper side of the top plate. The handle has an elongated hole along its length. A pin is fixedly connected to the top of the pull rod. The pin passes through the elongated hole and is slidably connected to it.

[0008] Compared with the prior art, the advantages of this utility model are: the overall height can be adjusted, thereby adjusting the height of the conveyed steel pipe, which facilitates docking with processing equipment. Multiple linearly arranged conveyor rollers support the steel pipe from below, and pressure rollers apply pressure to the steel pipe from above, ensuring the stability of longitudinal conveying.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Please see Figure 1-2This utility model provides a technical solution: a longitudinal steel pipe conveyor, including a rectangular mounting frame 2 and a support frame 1. Multiple conveying rollers 4 are equidistantly mounted on the mounting frame 2 along its length. Adjacent rollers are connected to each other via a pulley system at their ends. A reduction motor is fixedly connected to the side of the mounting frame 2, driving the conveying rollers 4 to rotate. After the reduction motor starts, all conveying rollers 4 rotate synchronously. Four symmetrical inserts 3 are located at the bottom of the mounting frame 2, with their lower ends correspondingly inserted into the legs of the support frame 1. A scissor-type lifting mechanism 5 (a mature existing product, not described in detail here) is mounted on the support frame 1. The top of the scissor-type lifting mechanism 5 is connected to the mounting frame 2 to adjust its height for easy docking with processing equipment.

[0014] Four symmetrical round rods 6 are fixedly connected to the top of the mounting frame 2. A top plate 7 is fixedly connected between the tops of the four round rods 6. A pressure plate 8 is slidably connected between the four round rods 6. A pressure roller 9 is installed on the lower side of the pressure plate 8. A spring 13 is sleeved on the round rod 6. The spring 13 applies downward pressure to the pressure plate 8. The pressure roller 9 and the conveying roller 4 are in the same vertical plane. The pressure roller 9 is used to press on the steel pipe, increasing the contact friction and reducing slippage. The pressure roller 9 and the conveying roller 4 have the same structural dimensions, and the outer side has a V-shaped annular groove along the circumference. The annular groove is used to clamp and constrain the steel pipe. A vertical pull rod 11 is fixedly connected to the upper end of the pressure plate 8. The pull rod 11 passes through the middle of the top plate 7 and is slidably connected to it. A handle 10 that can be tilted and flipped is hinged to the upper side of the top plate 7. The handle 10 has an elongated hole 12 along its length. A pin is fixedly connected to the top of the pull rod 11. The pin passes through the elongated hole 12 and is slidably connected to it. By pulling the handle 10 upward, the pressure roller 9 can be lifted upward through the pull rod 11 so that the steel pipe can be inserted.

[0015] Working principle: The height of the mounting frame 2 is adjusted by the scissor lifting mechanism 5, which in turn adjusts the height of the conveying roller 4 to facilitate docking with the processing equipment. During use, the steel pipe is placed on the conveying roller 4. After the conveying roller 4 rotates, it drives the steel pipe to move longitudinally to achieve conveying. The pressure roller 9 is pressed against the upper side of the steel pipe by the spring 13, increasing the driving friction of the conveying roller 4 on the steel pipe.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
