In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0034] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the invention can be understood according to the specific circumstances.

[0035] ​In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In one embodiment, a mounting support system of a box girder is described, which facilitates the butt joint of the box girder 1 and the support column 3 by cooperating the connecting seat 2, the receiving groove 321 and the positioning assembly 4 with each other, and facilitates the corresponding cooperation of the first connecting hole 322 and the second connecting hole 23 by the cooperation of the positioning assembly 4 and the positioning groove 21 when the connecting seat 2 of the box girder 1 is located in the receiving groove 321, and further facilitates the installation and fixation of the box girder 1 on the support column 3 by the staff using the locking assembly 5.

[0037] Specifically, referring to the drawings Figures 1 to 4 The mounting support system of the box girder includes a box girder 1, a locking assembly 5, a positioning assembly 4 and a support column 3. The support column 3 is provided in plurality, and the plurality of support columns 3 can be arranged on the ground to support the box girder 1. The lower end surface of the box girder 1 is provided with a plurality of connecting seats 2, and the connecting seat 2 is arranged one by one with the support column 3. Generally, the plurality of support columns 3 are arranged side by side along the direction perpendicular to the extension direction of the box girder 1. The upper end surface of each support column 3 is provided with a receiving groove 321, which is used to cooperate with the connecting seat 2, so that the box girder 1 is clamped and cooperated with the receiving groove 321 through the connecting seat 2, and then the box girder 1 is installed on the support column 3. It can be understood that by arranging the connecting seat 2 on the lower end surface of the box girder 1, when installing the box girder 1, the connecting seat 2 can be directly inserted into the receiving groove 321, and only the adjustment of the box girder 1 along the extension direction of the box girder 1 is needed, which greatly improves the installation efficiency and improves the butt joint accuracy of the box girder 1 and the support column 3.

[0038] The support column 3 is provided with a first connecting hole 322 which is communicated with the receiving groove 321, and the connecting seat 2 is provided with a second connecting hole 23 which is matched with the first connecting hole 322. When the box beam 1 is installed at a proper position of the support column 3, the first connecting hole 322 and the second connecting hole 23 can be correspondingly arranged to enable the locking assembly 5 to pass through the first connecting hole 322 and the second connecting hole 23 to realize the connecting and fixing of the connecting seat 2 and the support column 3. In order to quickly adjust the first connecting hole 322 and the second connecting hole 23 to the corresponding positions when the box beam 1 is arranged on the support column 3, the positioning assembly 4 is arranged in the receiving groove 321, and correspondingly, the positioning groove 21 which is suitable for being matched with the positioning assembly 4 is arranged on the connecting seat 2. When the connecting seat 2 is arranged in the receiving groove 321, the positioning assembly 4 is clamped and matched with the positioning groove 21 by adjusting the positional relationship between the box beam 1 and the receiving groove 321. At this time, the first connecting hole 322 and the second connecting hole 23 are correspondingly arranged, and then the locking assembly 5 passes through the first connecting hole 322 and the second connecting hole 23 to install and fix the box beam 1 on the support column 3.

[0039] It should be noted that in the prior art, the box beam 1 is generally directly installed on the support column 3, and then the positional relationship between the box beam 1 and the support column 3 is adjusted to enable the connecting holes to be aligned. However, due to the construction conditions on site, the box beam 1 is prone to deviation during adjustment, which requires a long time to adjust, is time-consuming and laborious, and is prone to knocking the box beam 1. In the present embodiment, when the connecting seat 2 is arranged in the receiving groove 321, the worker does not need to specially observe the positioning assembly 4, but only needs to move the box beam 1 to enable the positioning assembly 4 to be clamped and matched with the positioning groove 21, so that the alignment of the first connecting hole 322 and the second connecting hole 23 can be realized.

[0040] The implementation principle of the present embodiment is that the box beam 1 is transported by the hoisting mechanism, the connecting seat 2 is inserted into the receiving groove 321, and then the box beam 1 is further adjusted to move the box beam 1 relative to the receiving groove 321 along the extension direction of the box beam 1 until the positioning groove 21 of the connecting seat 2 moves to the position corresponding to the positioning assembly 4. The positioning assembly 4 is clamped and matched with the positioning groove 21, so that the box beam 1 cannot continue to move, which indicates that the box beam 1 has been moved to the position. At this time, the first connecting hole 322 and the second connecting hole 23 are correspondingly arranged, and then the worker uses the locking assembly 5 to pass through the first connecting hole 322 and the second connecting hole 23 to realize the connecting and fixing of the connecting seat 2 and the support column 3. In this process, the worker does not need to observe whether the first connecting hole 322 and the second connecting hole 23 are moved to the position, but only needs to move the box beam 1 along the extension direction of the box beam 1, so that the box beam 1 is determined to be installed to the position. The operation is convenient, the working efficiency is high, and the quality of the box beam 1 and the support column 3 is guaranteed.

[0041] In one embodiment, referring to the accompanying drawings Figure 3 and Figure 4 The embodiment further illustrates the positioning assembly 4. The positioning assembly 4 comprises an elastic member 41 and a positioning buckle 42. Correspondingly, a mounting groove 323 for mounting the elastic member 41 is arranged in the receiving groove 321. The elastic member 41 is mounted in the mounting groove 323, so that the elastic member 41 can move in the extension direction of the mounting groove 323. One end of the elastic member 41 is mounted on the bottom wall of the mounting groove 323. The positioning buckle 42 is mounted on the other end of the elastic member 41 and extends out of the mounting groove 323. The positioning buckle 42 is used to limit the cooperation with the positioning groove 42 under the action of the elastic member 41.

[0042] Generally, when the mounting groove 323 is arranged on the support column 3, the positioning buckle 42 is pressed by the box beam 1, so that the elastic member 41 is compressed and the positioning buckle 42 moves into the mounting groove 323. When the connecting seat 2 moves to the position where the positioning buckle 42 corresponds to the positioning groove 21, the positioning buckle 42 extends out of the mounting groove 323 under the action of the restoring force of the elastic member 41 and limits the cooperation with the positioning groove 323. In this way, the accurate alignment of the connecting seat 2 and the support column 3 is realized, so that the first connecting hole 322 and the second connecting hole 23 correspond to each other.

[0043] As a preferred, the connecting seat 2 is gap-fitted with the receiving groove 321 to ensure the stability of the connecting seat 2 when moving. The end of the positioning buckle 42 away from the elastic member 41 is hemispherical. Correspondingly, the positioning groove 21 is also hemispherical, which facilitates the relative movement of the connecting seat 2 in the receiving groove 321 and makes the positioning buckle 42 enter the positioning groove 21.

[0044] Further, referring to the accompanying drawings Figure 3 An extension 421 is arranged on the outer surface of the positioning buckle 42. Correspondingly, a limiting portion 325 is arranged at the opening of the mounting groove 323. The limiting portion 325 is arranged corresponding to the extension 421. The extension 321 is used to abut against the limiting portion 325 under the action of the elastic member 41. It can be understood that the arrangement of the extension 421 and the limiting portion 325 can limit the positioning buckle 42, so that the positioning buckle 42 is affected by the mounting groove 323 and is prevented from excessively extending out of the mounting groove 323, thereby ensuring the smooth butt joint with the positioning groove 21.

[0045] Further, the extension 421 is arranged along the circumference of the positioning buckle 42. A sliding groove 324 is arranged on the side wall of the mounting groove 323. One groove edge of the sliding groove 324 close to the positioning groove 21 coincides with the lower end surface of the limiting portion 325. The extension 421 is arranged in the sliding groove 324, so that the extension 421 can move up and down along the sliding groove 324 when the elastic member 41 is compressed or elongated, thereby ensuring the stability of the movement of the positioning buckle 42.

[0046] Of course, in actual production applications, the positioning assembly 4 can also be provided in other structures to achieve the purpose of initial positioning, which is not described one by one herein and is within the protection scope of the utility model.

Correspondingly, the receiving groove 321 is arranged on the column body along the extension direction of the support base 32, i.e. along the extension direction of the box girder 1, and is located on the side of the support base 32 away from the column body 31. Correspondingly, the first connecting hole 322 is arranged on the support base 32. Through the arrangement of the support base 32, the connecting contact area of the connecting seat 2 and the support column 3 can be improved, and the stability of the box girder 1 installed on the support column 3 can be improved.

[0048] Further, the side of the connecting seat 2 away from the box girder 1 is provided with a clamping groove 22, the clamping groove 22 is arranged along the extension direction of the connecting seat 2, i.e. along the extension direction of the box girder 1, and the two ends of the extension direction of the clamping groove 22 are in communication with the side walls of the two ends of the extension direction of the connecting seat 2. In addition, the positioning groove 21 is arranged on the top wall of the clamping groove 22, the clamping block 326 cooperating with the clamping groove 22 is arranged in the receiving groove 321 of the support base 32, the mounting groove 323 is arranged on the upper end face of the clamping block 326, and then the positioning assembly 4 is arranged on the upper end face of the clamping block 326, and correspondingly, the second connecting hole 23 is arranged on the connecting seat 2.

[0049] As preferred, as shown in the description accompanying drawings Figure 1 , the clamping groove 22 is arranged in the middle part of the connecting seat 2, and correspondingly, the clamping block 326 is also arranged in the middle part of the receiving groove 321.

[0050] In addition, two groups of locking assemblies 5 are arranged on each support column 3, the two groups of locking assemblies 5 are arranged on the opposite sides of the support column 3, i.e. on the opposite sides of the support base 32, and each group of locking assemblies 4 comprises a plurality of bolts, each bolt corresponds to one first connecting hole 322 and one second connecting hole 33, and the inner threads cooperating with the bolts are arranged in the first connecting hole 322 and the second connecting hole 33, so that the bolts are connected with the first connecting hole 322 and the second connecting hole 33 through threads.

[0051] In one embodiment, referring to the description accompanying drawings Figure 1At one end of the column body 31 away from the support base 32, a butt joint groove 311 is arranged, and a plurality of butt joint blocks 312 are arranged in the butt joint groove 311. It can be understood that, in order to increase the application range of the support column 3, the butt joint groove 311 is arranged at one end of the column body 31 to facilitate the clamping connection with the extension column, so as to extend the length of the support column 3 to meet the actual terrain requirements. A plurality of butt joint blocks 312 are generally arranged in the butt joint groove 311 of the support column 3, and the extension column is provided with a butt joint end, the butt joint end is inserted into the butt joint groove 311 and clamped between adjacent butt joint blocks 312, so as to achieve the extension and lengthening of the support column 3.
