Detailed Embodiment

[0021] It should be noted that the terms "first", "second", etc. in the description, claims and the above-mentioned drawings of this application are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. For the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0022] Referring to Figures 1 - 3 , a crawler frame of a hoisting crane, which includes an intermediate face plate 2 and two crawler limit frames 1. A movable baffle 4 is provided on one side of the crawler limit frame 1. Two fixing plates 10 are fixed to the outer wall of one side of the crawler limit frame 1 by bolts. Two second fixing columns 8 are fixed to the bottom of the two fixing plates 10 by bolts. A socket 7 is opened at the bottom of the second fixing column 8. A connecting plate 15 is fixed to one side of the movable baffle 4 by bolts. A bidirectional threaded rod 12 is rotatably connected inside the connecting plate 15. Fixing blocks 11 are threadedly connected to both ends of the bidirectional threaded rod 12. An insertion rod 6 is welded to the bottom of the fixing block 11, and the insertion rod 6 is inserted into the socket 7. Two connecting blocks 9 are fixed to one side of the movable baffle 4 by bolts. By using the cooperation of the second fixing column 8 and the connecting block 9, it is convenient for the staff to quickly and accurately position and install the movable baffle 4. And the second fixing column 8 is inserted into the connecting block 9. Rotate the bidirectional threaded rod 12 to make the fixing block 11 drive the insertion rod 6 to move towards the middle respectively until the insertion rod 6 moves out of the socket 7. Then pull down the movable baffle 4 to separate the connecting block 9 from the second fixing column 8, and then quickly complete the disassembly of the movable baffle 4.

[0023] In the present utility model, it should be noted that two first fixing columns 3 are fixed to the top of the movable baffle 4 by bolts, and the first fixing columns 3 pass through the crawler limit frame 1. The first fixing columns 3 are convenient for positioning the movable baffle 4, so that the staff can further accurately and quickly position the movable baffle 4 at the installation position of the crawler limit frame 1. Blocking blocks 13 are welded to both ends of the bidirectional threaded rod 12.
