Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel pipe transfer equipment, and in particular to an automatic lifting and tilting trolley for steel pipe transfer. Background Technology
[0002] In steel pipe production workshops, during the transfer of steel pipes, a pair of tilting arms are designed on the transfer trolley to maintain the basic bundle shape of the steel pipes because it is necessary to keep the bundle of steel pipes in a regular hexagonal arrangement.
[0003] Traditional tilting booms are equipped with cylinders or hydraulic cylinders to drive the tilting boom to tilt. However, during the steel pipe transfer process, the transfer trolley will move, and the air pipe or hydraulic pipe will be dragged along with the transfer trolley. This can easily lead to the hydraulic pipe joint or air pipe being pulled and broken, resulting in insufficient power of the tilting boom and failure to play its role in fixing and binding.
[0004] To avoid the above situation, a mechanism was specifically designed that automatically lifts and tilts while eliminating the drive device of the tilting arm. The tilting arm is automatically raised or lowered by the raising and lowering of the lifting trolley. Utility Model Content
[0005] The purpose of this utility model is to address the above-mentioned situation by providing an automatic lifting and tilting trolley for steel pipe transportation. The trolley has a novel structural design and utilizes its own mechanical structure linkage to achieve tilting and positioning without additional power, making it very convenient to use.
[0006] The specific solution of this utility model is as follows: a lifting automatic tilting trolley for steel pipe transfer, comprising a transfer trolley, on which a scissor fork lifting mechanism is installed, the top of which is connected to a scissor fork lifting platform, and four rectangular guide cylinders are arranged at the four corners of the scissor fork lifting mechanism, the bottom of which is fixed to the transfer trolley. A support rod is slidably inserted into each guide cylinder, and the tops of the four support rods jointly support and connect to a lifting frame, which is placed directly above the scissor fork lifting platform. The lifting frame rises or falls under the lifting support of the scissor fork lifting platform. A 60° tilting arm is provided on each of the front and rear sides of the lifting frame, and the two 60° tilting arms on the front and rear sides are arranged opposite each other from the main viewing angle. The 60° tilting arms near the middle are rotatably connected to the side wall of the lifting frame. The upper part of the 60° tilting arm is used to fix the steel pipe bundle, and the lower end of the 60° tilting arm is equipped with a roller, which makes rolling contact with the scissor fork lifting platform below.
[0007] Furthermore, the lifting frame described in this utility model has horizontally arranged adjustment slots on its front and rear side walls corresponding to the 60° tilting arm. The 60° tilting arm is connected to the adjustment slots via a rotating shaft. The rotating shaft can be adjusted in the adjustment slots to change its installation position. The rotating shaft is clamped to the side wall of the adjustment slots via front and rear fastening nuts.
[0008] Furthermore, the 60° tilting arm described in this utility model is a V-shaped structure composed of a long arm and a short arm. The connection point between the long arm and the short arm is rotatably connected to the front or rear side wall of the lifting frame. The long arm is used to fix the steel pipe bundle and contact the steel pipe carried on the lifting frame.
[0009] Furthermore, the transfer trolley described in this utility model has a movable platform, and the bottom of the movable platform is equipped with a pair of unpowered wheels and a pair of powered wheels, with the powered wheels driven by a motor.
[0010] Furthermore, in this utility model, the scissor lift platform is a platform surface, and the front-to-back width of the platform surface is greater than the front-to-back width of the lift frame.
[0011] Furthermore, in this utility model, the cross-section of the guide cylinder is a square hole or a circular hole, and the cross-sectional shape of the support rod matches the cross-sectional shape of the guide cylinder, with the support rod sliding up and down in the corresponding guide cylinder.
[0012] In this invention, the tilting arm is designed as a 60° tilting arm, and its tilting action is completed in conjunction with the lifting action of the scissor fork lifting platform. No additional power source is required for driving. The tilting of the 60° tilting arm is achieved at the same time as the lifting frame is lifting, which further realizes the shaping operation of steel pipe bundles. It has good practical application and promotion value. Attached Figure Description

[0018] See Figures 1-2This utility model relates to an automatic lifting and tilting trolley for transporting steel pipes. It comprises a transport trolley, and further, the transport trolley has a movable platform 2. The bottom of the movable platform is equipped with a pair of unpowered wheels 3 and a pair of powered wheels 1. The powered wheels are driven by a motor. A scissor-fork lifting mechanism is installed on the transport trolley, and a scissor-fork lifting platform 9 is connected to the top of the mechanism. Four rectangular guide cylinders 4 are arranged at the four corners of the scissor-fork lifting mechanism, with their bottoms fixed to the transport trolley. A support rod 11 is slidably inserted into each guide cylinder. Furthermore, the cross-section of the guide cylinder is a square or circular hole, and the cross-sectional shape of the support rod matches the cross-sectional shape of the guide cylinder. The support rods slide up and down in the corresponding guide cylinders, and the tops of the four support rods jointly support and connect to a lifting frame 10. Furthermore, the scissor lift platform in this utility model is a platform surface, and the front-to-back width of the platform surface is greater than the front-to-back width of the lifting frame. The lifting frame is placed directly above the scissor lift platform, and the lifting frame rises or falls under the lifting support of the scissor lift platform. A 60° flip arm 7 is provided on each of the front and back sides of the lifting frame. The two 60° flip arms on the front and back sides are arranged opposite each other from the main viewing angle. The 60° flip arms are rotatably connected to the side wall of the lifting frame near the middle part. The upper part of the 60° flip arm is used to fix the steel pipe bundle, and the lower end of the 60° flip arm is equipped with a roller 6. The roller makes rolling contact with the scissor lift platform below. Furthermore, in this invention, the front and rear side walls of the lifting frame are provided with transversely arranged adjustment slots 8 corresponding to the 60° tilting arm. The 60° tilting arm is connected to the adjustment slots via a rotating shaft. The rotating shaft can be adjusted in the adjustment slots, and is clamped to the side wall of the adjustment slots by front and rear fastening nuts. Furthermore, the 60° tilting arm in this invention is a V-shaped structure composed of a long arm 13 and a short arm 12. The connection point between the long arm and the short arm is rotatably connected to the front or rear side wall of the lifting frame. The long arm is used to fix the steel pipe bundle and contacts the steel pipe carried on the lifting frame.
[0019] The working process of this utility model:
[0020] See Figure 1 When the scissor lift platform descends to its lowest position, it separates from the lifting frame by a certain distance. The 60° tilting arm can tilt and fall freely under its own weight. However, at this time, the rollers maintain a slight contact with the scissor lift platform to keep the long arm horizontal and lower than the upper surface of the lifting frame, which facilitates the normal loading of steel pipe bundles on the lifting frame platform.
[0021] See Figure 2When the scissor lift platform rises to a high position, it pushes the lifting frame upwards. At the same time, the scissor lift platform contacts the bottom surface of the lifting frame. At this time, the roller drives the 60° tilting arm to rotate around the pivot. The 60° tilting arm is also lifted by the scissor lift platform. The power of the scissor lift is used to lift the 60° tilting arm. The long arm rises and tilts, maintaining a 60° angle to keep the bundle shape of the steel pipe unchanged.
[0022] In this invention, two 60° tilting arms are arranged at an oblique angle on the front and rear sides. The lateral position of the two 60° tilting arms in the adjusting slot can be adjusted to adapt to the width requirements of steel pipe bundles of different thicknesses, so as to achieve the purpose of shaping during the transfer process.
[0023] In this invention, the tilting arm is designed as a 60° tilting arm, and its tilting action is completed in conjunction with the lifting action of the scissor fork lifting platform. No additional power source is required for driving. The tilting of the 60° tilting arm is achieved at the same time as the lifting frame is lifting, which further realizes the shaping operation of steel pipe bundles. It has good practical application and promotion value.
