In this embodiment, the guide wheel mounting frame 2 is installed by the pin, so that the bearing capacity of the guide wheel mounting frame 2 is higher, the installation is more secure, and the guide wheel mounting frame 2 is prevented from falling off during operation.

[0034] It should be noted that the shaft hole, the through hole and the mounting pin form a fixing group, and the fixing group is provided in plurality. In this embodiment, the fixing group is provided in plurality to facilitate the fixing and installation of the guide wheel mounting frame 2.

[0035] It should be noted that, in the present embodiment, the guide wheel 3 is rotatably mounted on the guide wheel mounting frame 2 around a horizontal axis so as to be rolled and fitted onto the outer side wall of the tower body of the inner climbing tower crane.

[0036] Furthermore, the number of the guide wheels 3 is multiple groups, each group of the guide wheels has at least two guide wheels, the rotation axes of the two guide wheels 3 are arranged perpendicular to each other, and the two guide wheels 3 are respectively used to roll and fit to the adjacent two outer side walls of the crane tower section. In this embodiment, the two guide wheels 3 are respectively fitted to the adjacent two outer side walls of the main chord of the tower body to ensure the stable ascent of the inner climbing tower crane, avoid shaking during the activity, resulting in roller rolling failure and failure to play a guiding role.

[0037] On the other hand, in this embodiment, a plurality of groups of guide wheels 3 are arranged at intervals so that the inner-climbing tower crane can move between them, thereby ensuring the normal lifting of the inner-climbing tower crane and avoiding uneven force.

[0038] For further information, see Figure 2 The tower crane inner climbing frame 100 further includes a connecting beam 4, which is disposed between the two rolling groups and fixedly connected to the two installation beams 1. In this embodiment, the two installation beams 1 are fixedly connected by the connecting beam 4, which facilitates the overall installation of the tower crane inner climbing frame 100, and can ensure the spacing between the two installation beams 1 to avoid installation errors.

[0041] Specifically, in the present embodiment, two guide wheel mounting frames 2 are provided, and the two guide wheel mounting frames 2 are spaced apart to allow the side walls on both sides of the tower crane to slide respectively.

[0042] On the other hand, see Figure 3The mounting crossbeam 1 is also provided with a bearing block 5, which is movably mounted on the mounting crossbeam 1 in the horizontal direction. The bearing block 5 has a first position for moving to place the base of the inner climbing tower crane, and a second position for moving to avoid the inner climbing tower crane. The guide wheel mounting frame 2 on the mounting crossbeam 1 facilitates the normal lifting and sliding of the tower crane. After the tower crane is lifted, it is necessary to ensure the fixed position of the tower crane. In this embodiment, the bearing block 5 is arranged on the mounting crossbeam 1. After the tower crane is lifted, the bearing block 5 is moved so that the bottom of the tower crane can be placed on the bearing block 5. When the tower crane needs to be lifted, the bearing block 5 moves to the second position to avoid affecting the movement of the tower crane.

[0043] It should be noted that there are many ways to movably install the bearing block 5 on the mounting beam 1 , such as directly driving the bearing block 5 to be installed on the mounting beam 1 through a driving cylinder or the like.

[0045] Furthermore, the guide groove is extended in the up-down direction, wherein the first position is at the lower end of the second position. In this embodiment, the guide groove is also extended in the up-down direction, so that when no external force is applied to the limit block, the limit block 5 will naturally move to the first position to carry the tower crane, and when the tower crane moves, it only needs to push the limit block 5 to move to the second position, which is simple and reliable to operate, and can realize automatic load locking of the tower crane.

[0046] Furthermore, a first positioning hole is provided on the inner side wall of the guide groove corresponding to the first position, and a second positioning hole is provided corresponding to the second position; a mounting hole is formed on the bearing block 5; the inner climbing frame of the tower crane includes two positioning pins 61, and the two positioning pins 61 are respectively penetrated in the first positioning hole and the second positioning hole, so as to be penetrated and fixed to the mounting hole when the limit block is in the first position or the second position. In this embodiment, the bearing block 5 can be fixed in the first position or the second position by the positioning pins 61, so as to avoid deviation of the position of the bearing block 5 and ensure the stability of the position of the bearing block 5.

[0047] In addition, the inner climbing frame of the tower crane further includes a positioning rod 7, which is movably installed in the guide groove along the extension direction of the guide groove and is located on the side of the bearing block 5 facing the second position, and one end of the positioning rod 7 abuts against the bearing block 5 to drive the bearing block 5 to move toward the first position.
