[0014] Further, the specific structure of the temporary support is not uniquely limited in the scheme, one possible solution is that the temporary support comprises a sand bucket and a support column arranged in the sand bucket, when this solution is adopted, the support column is pressed into the sand bucket by the support, and the support force is flexibly adjusted by the sand bucket.

[0015] Further, in order to facilitate the installation of the guide block, one possible solution is that a groove is formed on the guide block, and a flange matched with the groove is formed on the support, when this solution is adopted, the flange is inserted into the groove to complete the installation of the guide block, realizing the quick installation of the guide block.

[0016] Further, in order to reduce the friction force between the first inclined surface and the second inclined surface, one possible solution is that a plurality of rollers are arranged on the first inclined surface, when this solution is adopted, since the second inclined surface and the rollers are in rolling friction, the friction force is further reduced.

[0038] A support 2 is installed on the crossbeam 1;

[0039] A guide block 3 is installed on both sides of the support 2, and a first inclined surface 31 is formed on the guide block 3;

[0040] A limiter 4 is installed on the crossbeam 1, and a second inclined surface 41 in contact with the first inclined surface 31 is formed on the limiter 4.

[0041] The existing construction process requires high hoisting precision because the support is usually assembled by bolts, and the position of the support needs to be adjusted multiple times during hoisting. In the present scheme, the support 2 is lifted and moved above the crossbeam 1 by a hoisting machine, and as the support 2 slowly descends, the first inclined surface 31 on the guide block 3 comes into contact with the second inclined surface 41 on the limiter 4, until the support 2 is positioned by sliding into the middle of the two limiters 4, avoiding the need to adjust the position of the support 2 multiple times in the traditional scheme, and solving the problem of the need to adjust the position of the support multiple times during hoisting.

[0042] In order to reduce the stress on the limiter 4, one of the feasible schemes is to arrange a temporary support 5 between the crossbeam 1 and the support 2. When this scheme is adopted, the temporary support 5 can assist in supporting the support 2, thereby reducing the force between the guide block 3 and the limiter 4, and further reducing the stress on the limiter 4.

[0043] Please refer to Figure 2The present scheme does not uniquely limit the specific structure of the temporary support 5, wherein one possible scheme is that the temporary support 5 comprises a sand bucket 51 and a support column 52 arranged in the sand bucket 51, and when this scheme is adopted, the support column 52 is pressed into the sand bucket 51 by the support 2, and the support force is flexibly adjusted through the sand bucket 51.

[0044] With reference to Figure 3 and Figure 5 , in order to facilitate the installation of the guide block 3, one possible scheme is that a groove 32 is formed on the guide block 3, and a flange 21 matched with the groove 32 is formed on the support 2, and when this scheme is adopted, the installation of the guide block 3 is completed by inserting the flange 21 into the groove 32, and the quick installation of the guide block 3 is realized.

[0045] In order to reduce the friction between the first inclined surface 31 and the second inclined surface 41, one possible scheme is that a plurality of rollers (not shown in the figure) are arranged on the first inclined surface 31, and when this scheme is adopted, the rolling friction is formed between the second inclined surface 41 and the rollers, thereby reducing the friction.

[0046] With reference to Figure 1 and Figure 4 , in order to facilitate the installation and removal of the limit stop 4, one possible scheme is that a bolt 42 penetrating through the limit stop 4 is arranged on the cross beam 1, and a nut 43 is arranged on the bolt 42, and when this scheme is adopted, the limit stop 4 can be conveniently and quickly installed or removed.

[0047] The working principle of the present embodiment is as follows:

[0049] In order to solve the problem of the need for multiple adjustments of the position of the support during the lifting process, in the present scheme, the support 2 is lifted and moved above the cross beam 1 by the hoisting machine, and as the support 2 slowly descends, the first inclined surface 31 on the guide block 3 contacts the second inclined surface 41 on the limit stop 4 until the support 2 is positioned by sliding between the two limit stops 4, thereby avoiding the need for multiple adjustments of the position of the support 2 in the traditional scheme and solving the problem of the need for multiple adjustments of the position of the support during the lifting process.

[0050] In order to reduce the stress received by the limit stop 4, in the present scheme, the temporary support 5 is arranged between the cross beam 1 and the support 2, which assists in supporting the support 2, thereby reducing the acting force between the guide block 3 and the limit stop 4 and further reducing the stress received by the limit stop 4.

[0051] In order to facilitate the installation of the guide block 3 on the support 2, in this scheme, since the guide block 3 is formed with a groove 32, the support 2 is formed with a flange 21 matched with the groove 32, the flange 21 is inserted into the groove 32, the installation of the guide block 3 is completed, and the quick installation of the guide block 3 is realized.
