Definitions
- the present invention relates to the technical field of crane booms, and more particularly to a crane boom transition structure.
- truss arms of cranes typically consist of a plurality of arm sections.
- the section of the arm section is generally a rectangle such as a rectangle.
- the section dimensions of the arm sections are usually different depending on the design requirements of the crane. For the book
- a crane boom transition structure of the present invention includes an arm joint, a transition joint and a support structure, wherein the arm joint is matched with the transition joint and fixedly connected, and the support structure is The upper end is fixedly connected to the upper end of the side of the arm section, the lower end and the transition section
- the above-mentioned crane boom transition structure wherein the support structure is a box beam, and a box beam is disposed on each side of the corresponding arm section.
- each side of the corresponding arm joint is provided with a ⁇ -shaped arm, wherein the side surface is an outer side of the arm joint, including adjacent Two sides.
- the crane boom transition structure of the present invention increases the rigidity of the transition portion of the crane boom by adding a support structure between the crane arm section and the transition joint, and increases the rigidity and stability of the crane boom as a whole, and the structure thereof Simple, easy to install, low production cost, can be widely used in all types of cranes.
- FIG. 1 is a schematic view showing a transition structure of a crane boom in the prior art
- Figure 5 is a schematic illustration of a support structure in a first preferred embodiment of the crane boom transition structure of the present invention
- Figure 6 is a perspective view of the three-dimensional structure of Figure 5;
- Figure 7 is a schematic view showing a transition structure of a crane boom in a second preferred embodiment of the present invention
- Figure 8 is a perspective view of the three-dimensional structure of Figure 7;
- Figure 9 is a schematic illustration of a support structure of a second preferred embodiment of the crane boom transition structure of the present invention.
- Figure 10 is a perspective view of the structure of Figure 9. detailed description
- the crane boom is a combination of multiple arm joints.
- a transition section as a connection between the two arm sections.
- the crane boom transition structure of the present invention can achieve a stable connection between the arm section and the transition section, so that the entire boom can be stably operated.
- the boom transition structure comprises an arm joint, a transition joint and a support structure.
- the boom is matched with the transition joint, that is, one end surface of the transition joint is the same as the end surface of the arm joint, and can be fixedly connected together.
- the upper end of the support structure is fixedly connected with the upper end of the side of the arm section, the lower end is fixedly connected with the lower end of the corresponding side of the transition section, and the middle is fixedly connected with the connection point of the side of the arm section and the side of the corresponding transition section.
- the support structure is supported by steel pipes.
- seamless steel pipes can be used.
- the support structure is fixedly connected to the arm joint and the transition joint by a pin or a high-strength bolt. The above structure fully ensures the stability of the transition portion of the crane boom and the rigidity of the entire boom.
- the support structure is a box beam. 3, FIG.
- FIGS. 5 and 6 are a transition structure of a crane boom to which a box beam 3 is mounted, and the specific structure of the box beam 3 is as shown in FIGS. 5 and 6.
- the upper end, the lower end and the middle of the box beam 3 are respectively at the upper end of the side of the arm section 1, the lower end of the side of the transition section 2, the arm section. 1 and the side connection points of the transition section 2 are fixedly connected.
- the pin shaft used for the fixed connection can be flexibly moved on the box beam, and is connected with the arm joint 1 and the transition joint 2 at a suitable position, thereby effectively reducing the sharpness of the boom reducer, and ensuring the sharpness.
- the stability and rigidity of the entire boom can be flexibly moved on the box beam, and is connected with the arm joint 1 and the transition joint 2 at a suitable position, thereby effectively reducing the sharpness of the boom reducer, and ensuring the sharpness.
- the support structure is a ⁇ -shaped arm.
- Fig. 7, Fig. 8 shows the transition structure of the crane boom equipped with the squat arm 4, and the concrete structure of the squat arm 4 is as shown in Figs. 9 and 10.
- the jaw arm 4 is of a trapezoidal configuration mounted on one side of the arm section 1, which is an outer side of the arm section and includes adjacent two sides.
- the upper end of the jaw arm 4 is connected to the upper end of the side surface, and the lower end is connected to the lower end of the corresponding side of the transition section 2.
- the middle portion of the jaw arm 4 is fixedly connected to the joint of the arm section 1 and the transition section 2 at the side.
- the pin used for the fixed connection can be flexibly moved over the jaw arm to connect to the arm section and transition section at the appropriate location.
- the crane boom transition structure of the present invention increases the rigidity of the transition portion of the crane boom by adding a support structure between the crane boom section and the transition joint, thereby increasing the rigidity and stability of the crane boom as a whole.
- the utility model has the advantages of simple structure, convenient installation and low production cost, and can be widely applied to various types of cranes.
