[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Example:

[0028] like Figure 1-Figure 7As shown, the utility model provides an adjustable steel box girder support frame, including an adjustment section and a plurality of standard sections. The plurality of standard sections are stacked up layer by layer. The adjustment section is stacked on the top of the standard section. The structure of the standard section can be the same as the conventional tower crane structure, as long as it can be stacked up layer by layer and connected. The adjustment section includes an outer tube 1, an adjustment tube 2 and an adjustment rod 3. The inner wall of the outer tube 1 is provided with a plurality of support platforms 4 along its height direction. The support platform 4 protrudes from the inner wall of the outer tube 1. The adjustment tube 2 is inserted into the inner wall of the outer tube 1 and the outer wall of the adjustment tube 2 is provided with a support block 5 in cooperation with the support platform 4. When the support block 5 is placed above the support platform 4, the support platform 4 supports the support block 5, thereby supporting the adjustment tube 2. A channel 6 for the adjustment tube 2 and the support block 5 to enter and exit is also provided inside the outer tube 1, so that the support block 5 can be extended and retracted along the adjustment tube 2 and corresponds to each support platform 4. The adjustment tube 2 is provided with an internal thread. The adjustment rod 3 is threadedly connected to the inside of the adjustment tube 2. The adjusting rod 3 can be rotated and extended relative to the adjusting tube 2 by rotating the adjusting rod 3 .

[0029] When the adjustable steel box beam support frame of the utility model is used, a plurality of standard sections are stacked one by one, so that the height of the support frame is equal to the required height. Then the adjustment section is placed on the top of the standard section. Finally, the height of the adjustment section is adjusted to make the height of the temporary support frame the required height.

[0030] When adjusting the height of the adjustment section, first rotate the adjustment tube 2 so that the support block 5 rotates into the channel 6. At this time, the support block 5 can move along the channel 6, so that the adjustment tube 2 can quickly move along the outer tube 1 to adjust the length of the adjustment tube 2 extending out of the outer tube 1. When the length of the adjustment tube 2 extending out of the outer tube 1 is adjusted appropriately, rotate the adjustment tube 2 so that the support block 5 rotates to the top of the support platform 4 corresponding to this height. This process can be regarded as a coarse adjustment, and its purpose is to quickly adjust the height to near the required height. Finally, rotate the adjustment rod 3 so that the adjustment rod 3 and the adjustment tube 2 can be extended and retracted relative to the adjustment tube 2 under the action of the threaded fit, and then the height of the support frame can be fine-tuned to the required height.

[0031] This support frame can be quickly adjusted to a height close to the required height through rough adjustment, thereby improving the adjustment efficiency. Then, it can be fine-tuned to the required height through fine adjustment to adjust the accuracy. This adjustable steel box girder support frame can ensure both the adjustment speed and the adjustment accuracy of the temporary support frame.

[0032] In this embodiment, the support platforms 4 are arranged in pairs and the two support platforms 4 of each pair are distributed on the opposite side walls of the outer tube 1. Two support blocks 5 are provided and the two support blocks 5 are arranged on the outer walls of the opposite sides of the adjusting tube 2. This makes each support block 5 correspond to a number of support platforms 4. At the same time, support blocks 5 are provided on both sides of the adjusting tube 2, so that both sides of the adjusting tube 2 are well supported, thereby making the support of the adjusting tube 2 more stable. Along the circumference of the outer tube 1, the center angle covered by each support platform 4 is less than 90 degrees. The center angles corresponding to the two channels 6 are greater than 90 degrees. Along the circumference of the adjusting tube 2, the center angle covered by each support block 5 is less than 90 degrees. The size of the two support blocks 5 is smaller than the size of the channel 6, thereby ensuring that the support blocks 5 can smoothly pass through the channel 6 to adjust the extension length of the adjusting tube 2.

[0033] In practice, the number of support blocks 5 can be multiple and the multiple support blocks 5 are distributed around the adjusting tube 2, so that the adjusting tube 2 is evenly supported all around and the supporting effect is better.

[0034] In this embodiment, a plurality of support platforms 4 are distributed in two rows inside the outer cylinder 1. This allows two channels 6 to penetrate both ends of the outer cylinder 1, thereby facilitating the passage of the support blocks 5.

[0035] The middle of the support platform 4 and the middle of the support block 5 are both provided with a limiting hole 7. A limiting rod 8 is also included to cooperate with the limiting hole 7, so that the limiting rod 8 can be inserted into the limiting hole 7. When the extended length of the adjustment tube 2 is adjusted, the limiting holes 7 of the support platforms 4 and the limiting holes 7 of the support block 5 are located in a straight line. At this time, the limiting rod 8 can be inserted into the limiting hole 7, thereby locking the relative position of the support block 5 and the support platform 4. The two limiting rods 8 can limit the two sides of the adjustment tube 2, thereby preventing the adjustment tube 2 from rotating during use and causing the support block 5 to separate from the support platform 4 and cause an accident.

[0036] In this embodiment, the adjusting rod 3 is also sleeved with a locking nut 9. The locking nut 9 is threadedly connected to the adjusting rod 3. When the extended length of the adjusting rod 3 is adjusted, the locking nut is tightened on the adjusting tube 2 to lock the adjusting rod 3 and prevent the adjusting rod 3 from rotating during use.

[0037] In this embodiment, the adjusting section includes a connecting portion 10 and a supporting portion. The connecting portion 10 is provided with a connecting head in conjunction with the standard section, so that the connecting portion 10 can be conveniently connected to the standard section. The supporting portion is provided at the top of the connecting portion 10. The connecting portion 10 includes an outer tube 1, an adjusting tube 2 and an adjusting rod 3. The outer tube 1 is connected to the top of the connecting portion 10. The connecting portion 10 is provided in a rectangular shape. Figure 6 As shown, four groups of support parts are provided and each group of support parts corresponds to a corner of the connecting part 10. The box beam is supported by four adjustment rods 3. This is an implementation of the utility model.

[0038] There is another embodiment of the present invention, that is, a group of support parts are provided. The support part is provided in the middle of the connecting part 10. Figure 7 As shown, the box beam can be supported by an adjusting rod 3. In practice, the number and location of the supporting parts can be set as needed to meet actual needs.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
