[0038] In order to make the content of the present utility model easier to be clearly understood, the following further details the present utility model according to specific embodiments in conjunction with the accompanying drawings.

[0039] As Figures 1-6 shown, a movable bench for steel pipe transportation includes:

[0040] A support base 1;

[0041] A movable hinge frame 2, which is hingedly installed on the support base 1. The movable hinge frame 2 has at least a first position and a second position during the movement process. A tabletop suitable for the passage of pipes is provided on the movable hinge frame 2;

[0042] A first - position locking mechanism, which is respectively installed on the support base 1 and the movable hinge frame 2. The first - position locking mechanism is suitable for locking the relative position of the movable hinge frame 2 and the support base 1 when the movable hinge frame 2 is in the first position;

[0043] A second - position limiting mechanism, which is respectively installed on the support base 1 and the movable hinge frame 2. The second - position limiting mechanism is suitable for restricting the further rotation of the movable hinge frame 2 when the movable hinge frame 2 rotates to the second position.

[0044] In this embodiment, as Figures 1-2 shown, during the normal use process, the movable hinge frame 2 remains in the first position. Multiple movable benches for steel pipe transportation are placed side by side, and the pipes roll over the movable hinge frame 2. At this time, the movable hinge frame 2 in the first position is locked in the first position by the first - position locking mechanism, ensuring the normal and safe passage of the pipes. When personnel need to pass through the movable hinge frame, the first - position locking mechanism is opened, and the movable hinge frame is pushed to the second position. The second - position limiting mechanism restricts the further rotation of the movable hinge frame 2 to prevent the risks that may be brought by excessive rotation. The whole process can flexibly realize the opening and closing of the movable hinge frame 2, facilitating the passage of personnel, improving safety and increasing work efficiency. It meets various work requirements. The first - position locking mechanism ensures that the movable hinge frame 2 can be firmly locked in the first position, preventing accidental movement during the work process and improving work safety.

[0045] Specifically, as Figure 1 and Figures 3-5 shown, the first position locking mechanism can be structured as follows, including:

[0046] A connecting pin 31 is arranged on the movable hinge frame 2. The connecting pin is provided with an end, and the end is provided with a connecting portion having a circular cross-section. A necking section connected to the connecting portion is further arranged on the middle section of the connecting pin 31;

[0047] A connecting socket 32 is arranged on the support base 1. The connecting socket 32 is provided with a fitting groove adapted to cooperate with the connecting pin 31. The fitting groove is successively provided with a guiding conical surface, a locking convex section adapted to cooperate with the necking section, and a connecting portion receiving cavity adapted to cooperate with the connecting portion from outside to inside.

[0048] Specifically, as Figure 3 and Figure 5 shown, the locking convex section is provided with ball receiving cavities on both the upper and lower sides of the fitting groove;

[0049] The steel pipe conveying movable gantry also includes balls 33 and a compression spring 34. The balls 33 are arranged in the ball receiving cavities and partially extend out of the ball receiving cavities;

[0050] The compression spring 34 is arranged in the ball receiving cavity and abuts against the inner wall of the ball receiving cavity and the balls 33 respectively;

[0051] Wherein, when the connecting pin 31 is inserted into the fitting groove, the compression spring 34 is adapted to push the balls 33 to be locked into the necking section of the connecting pin 31.

[0052] In this embodiment, as Figure 3 and Figure 5 shown, the first position locking mechanism provides a convenient locking function for the steel pipe conveying movable gantry at the first position. The cooperation between the connecting pin 31 and the connecting socket 32 realizes quick and accurate locking. The design of the circular connecting portion and the necking section on the connecting pin 31 forms a match with the guiding conical surface, the locking convex section and the connecting portion receiving cavity in the connecting socket 32, ensuring the smoothness and stability of the locking process. The balls 33 and the compression spring 34 further enhance the reliability and operation convenience of the locking mechanism. The balls 33 partially extend out of the ball receiving cavities and can be flexibly locked into the necking section of the connecting pin 31 under the action of the compression spring 34. This design not only provides additional fixing force but also realizes a self-locking function to prevent the connecting pin 31 from accidentally coming out. At the same time, the design of the balls 33 also makes the unlocking operation simple and easy. Only by applying an appropriate force can the pressure of the compression spring 34 be overcome to achieve quick unlocking.

[0053] During actual use, when the operator adjusts the movable hinge frame 2 to the first position, only need to insert the connecting pin 31 into the mating groove of the connecting socket 32. The guiding conical surface can guide the connecting pin 31 to accurately enter. Then, the locking convex section cooperates with the necking section, and finally the connecting part enters the connecting part receiving cavity to complete the locking. At this time, the pressure spring 34 pushes the ball 33 into the necking section to form a stable locking state. This not only ensures the stability and safety of the steel pipe conveying movable platform during use, but also improves the convenience and efficiency of operation. Whether it is locking or unlocking, it can be completed quickly and easily, fully meeting the requirements in different working environments.

[0054] Specifically, as Figures 1-4 shown, the second position limiting mechanism can be of the following structure, including:

[0055] A fixing member 41, the fixing member 41 is installed on the support base 1, and the fixing member 41 is provided with a receiving groove;

[0056] A movable member 42, the movable member 42 is installed on the movable hinge frame 2, and the movable member 42 is adapted to be inserted into the receiving groove.

[0057] Specifically, as Figures 2-3 shown, the second position limiting mechanism further includes a magnetic member, the magnetic member is installed on the fixing member 41, and the magnetic member is adapted to generate magnetism and magnetically cooperate with the movable member 42 opposite to the fixing member 41.

[0058] In this embodiment, as Figures 1-4 shown, the second position limiting mechanism provides a stable and reliable position fixing function for the steel pipe conveying movable platform. The fixing member 41 is installed on the support base 1, and the receiving groove provided thereon provides an accurate positioning space for the movable member 42. The movable member 42 is installed on the movable hinge frame 2 and can be inserted into the receiving groove when needed to achieve mechanical limiting.

[0059] The magnetic member further enhances the functionality and convenience of use of the second position limiting mechanism. The magnetic member can be installed on the fixing member 41, and by generating magnetism, it magnetically cooperates with the corresponding component to provide an additional fixing force. This magnetic adsorption not only increases the positioning accuracy, but also enables the movable hinge frame 2 to be automatically adsorbed and fixed when reaching the second position without additional manual operation. At the same time, the magnetic adsorption is also convenient for quick release, making the adjustment of the movable hinge frame 2 more flexible and efficient.

[0060] During actual use, when the operator rotates the movable hinge frame 2 to the second position, the movable member 42 will insert into the receiving groove of the fixed member 41. At the same time, since the magnetic member generates magnetic force, the fixing effect is further enhanced. When position adjustment is required, the operator only needs to apply a slight force to overcome the magnetic force and move the movable hinge frame 2 away from the second position. This design not only ensures the firmness of the structure but also takes into account the convenience of use, reflecting the humanization and high efficiency of the product design.

[0061] In some embodiments, the magnetic member is mounted on the movable member 42, and the magnetic member is adapted to generate magnetism and magnetically cooperate with the fixed member 41 opposite to the movable member 42.

[0062] The magnetic member can be a magnet, and of course, it can also be an electromagnet.

[0063] Specifically, as Figure 1 、 3 and Figure 6 shown, a cross-frame is further provided on the movable hinge frame 2;

[0064] The steel pipe conveying movable bench further includes a slewing mechanism 21, and the slewing mechanism 21 is rotatably mounted on the cross-frame.

[0065] Specifically, as Figures 1-2 shown, a sealing cavity is further provided between the slewing mechanism 21 and the cross-frame, and the sealing cavity is filled with grease.

[0066] Specifically, as Figures 1-2 shown, the slewing mechanism 21 includes a plurality of bearings that are rotatably mounted on the cross-frame and are connected side by side.

[0067] In this embodiment, as Figures 1-2 shown, the design of filling the sealing cavity of the bearing with grease ensures the smooth operation and long service life of the slewing mechanism 21. The presence of the grease reduces the friction between mechanical components, reduces wear, and also reduces noise, improving the overall smoothness of operation.

[0068] In actual application, the operator can horizontally adjust the position of the pipe through the slewing mechanism 21 according to different working requirements. Horizontally means moving between multiple steel pipe conveying movable benches.

[0069] Specifically, as Figure 1 and Figure 4 shown, mounting support feet are provided on the support base 1.

[0070] Specifically, a plurality of fixing screw holes are provided on the mounting support feet.

[0071] Specifically, as Figure 1 and Figures 3-4As shown, the support base 1 is further provided with a reinforcing rib 11, and the reinforcing rib 11 is installed between the outer surface of the support base 1 and the mounting support foot.

[0072] In this embodiment, if Figure 1 and Figures 3-4 As shown, the mounting support foot of the support base 1 is an important part of the steel pipe conveying movable platform in contact with the ground, which provides stable support. The multiple fixing screw holes on the mounting support foot increase the practicality of the steel pipe conveying movable platform, so that it can be firmly fixed on the ground as needed, and is suitable for various working environments. It is suitable for situations where long-term fixed use or use in an environment with large vibration is required.

[0073] The design of the reinforcing rib 11 further improves the stability and load-bearing capacity of the entire structure. The reinforcing rib 11 is installed between the outer surface of the support base 1 and the mounting support foot, forming a triangular structure, which effectively disperses the force transmitted from above and reduces the possibility of deformation of the support base 1. In the case of needing to carry heavier pipes, it not only enhances the overall rigidity, but also extends the service life of the equipment.

[0074] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
