[0029] Through the cooperation of the positioning device 9, the box body 14, the rotating shaft 15 and the supporting arm 13, after the main body 11 of the spanning frame is rotated to a vertical state, one side of the box body 14 is fitted with the inner wall of the groove plate 6. When the box body 14 rotates, the square plates 907 on both sides will be driven to move synchronously, so that the square plates 907 on both sides can drive the roller frame 902 to move through the third round rod 908, so that the roller frame 902 can drive the roller 901 to move into the groove of the inner wall of the groove plate 6. Under the action of the groove on the inner wall of the groove plate 6, the box body 14 can make the rollers 901 on both sides move relative to each other while rotating, so that the third round rods 908 on both sides can be inserted into the gap on the surface of the main body 11 of the spanning frame, so that the position of the main body 11 of the spanning frame can be preliminarily fixed. By fixing the main body 11 of the spanning frame during installation, the present invention is more convenient to use.

[0030] The locking device 8 includes a second cylinder 801, a gear 802, a baffle 803, a second spring 804, a vertical rod 805, a through-hole plate 806, a round block 807, a rack 808, a clamping block 809 and a bracket 810; The bracket 810 is fixedly connected to the groove plate 6, and the bracket 810 is fixedly connected to the second cylinder 801.

The rotating shaft of the gear 802 is rotatably connected to the round block 807, and the round block 807 can support the gear 802 to rotate. The round block 807 is fixedly connected to the groove plate 6, and the rotating shaft of the gear 802 is fixedly connected to the baffle 803. The rotation of the gear 802 can drive the baffle 803 to rotate. The baffle plate 803 is slidably connected to the vertical rod 805 through the through hole opened on the surface, and the lower end of the vertical rod 805 is symmetrically fixedly connected with a clamping block 809. The outer wall of the clamping block 809 is tightly pressed against the groove opened at the lower end of the through-hole plate 806. The clamping block 809 can be clamped with the groove at the lower end of the through-hole plate 806 to fix the position and angle of the vertical rod 805.

The second spring 804 can push the vertical rod 805 back to its original position, and the lower end of the second spring 804 fits with the baffle plate 803.

[0031] Through the cooperation of the locking device 8 and the groove plate 6, the telescopic end of the second cylinder 801 is shortened to drive the rack 808 to move synchronously, so that the baffle 803 can be pressed against the spanning frame body 11 and one side of the groove plate 6. At the same time, the operator presses the vertical rod 805 downward so that the lower end of the vertical rod 805 can drive the blocks 809 on both sides to penetrate the through-hole plate 806. When the vertical rod 805 moves, the second spring 804 can be compressed. At the same time, the vertical rod 805 is rotated so that the blocks 809 on both sides can be pressed against the spanning frame body 11 and the groove plate 6. The bracket 800 is rotated 90° so that the blocks 809 on both sides can be aligned with the grooves at the lower end of the through-hole plate 806, and the vertical rod 805 is loosened. The vertical rod 805 can move upward under the push of the second spring 804, so that the vertical rod 805 drives the blocks 809 on both sides to engage with the grooves at the lower end of the through-hole plate 806, so that the position of the baffle 803 is fixed, and the position of the spanning frame body 11 is fixed. By further fixing the spanning frame body 11 quickly, the present invention is more convenient to install.

The upper right side of the spanning frame body 11 is fixedly connected to a pull ring 10, which can be pulled by a crane so that the spanning frame body 11 can rotate around the rotating shaft 15.

[0033] Working principle: When disassembling and installing the crossing frame: First, the base 1 is moved to a designated location and placed so that the four sets of supporting legs 7 are in contact with the horizontal ground. When the ground is uneven, a horizontal base can be made of cement or the like.

[0034] Base fixing process: The first cylinders 202 on both sides are controlled to work, so that the telescopic ends of the first cylinders 202 on both sides extend and drive the transmission plate 205 to move through the first round rod 204. The transmission plate 205 can pull the arc plate 206 to move through the support blocks 207 on both sides, so that one end of the arc plate 206 moves out of the interior of the frame 203. The operator pulls the arc plates 206 on both sides to rotate the arc plates 206 at the hinges with the support blocks 207 on both sides, so that the insertion rod 4 between the arc plate 206 and the supporting plate 201 can be pulled, so that the insertion rod 4 is rotated at the hinges between the ring 5 and the base 1, and the insertion rod 4 is rotated to a vertical state. The insertion rod 4 is knocked into the ground by equipment such as a pile driver, so that the upper protruding part of the insertion rod 4 is pressed against the ring 5. When there is a base, the insertion rods 4 on both sides can be inserted into the holes reserved in the base to fix the position of the base 1.

[0035] Installation process: Insert one end of the two span frame bodies 11 into the inside of the boxes 14 on both sides respectively, connect one end of the wire rope of the crane to the pull ring 10, and use the crane to pull the span frame body 11 to rotate around the hinge of the rotating shaft 15 and the support arm 13. When the span frame body 11 rotates to a vertical state, one side of the box 14 fits with the inner wall of the groove plate 6. When the box 14 rotates, it will drive the square plates 907 on both sides to move synchronously, so that the square plates 907 on both sides can pass through the third round rod. 908 drives the roller frame 902 to move, so that the roller frame 902 can drive the roller 901 to move into the groove of the inner wall of the groove plate 6. Under the action of the groove of the inner wall of the groove plate 6, the box body 14 can make the rollers 901 on both sides move relative to each other while rotating. The rollers 901 on both sides can push the third round rods 908 on both sides to pass through the square plate 907, so that the third round rods 908 on both sides can be inserted into the gap on the surface of the crossing frame body 11, so that the position of the crossing frame body 11 can be preliminarily fixed.

[0036] Locking process: The second cylinder 801 is controlled to work, so that the telescopic end of the second cylinder 801 is shortened to drive the rack 808 to move synchronously, and the gear 808 can drive the gear 802 to rotate while moving, so that the gear 802 can drive the baffle 803 to rotate synchronously, so that the baffle 803 can be pressed against the span frame body 11 and one side of the groove plate 6, and at the same time, the operator presses the vertical rod 805 downward, so that the lower end of the vertical rod 805 can drive the blocks 809 on both sides to penetrate the through-hole plate 806, and the second spring 804 can be moved while the vertical rod 805 moves. Compress and rotate the vertical rod 805 at the same time, so that the blocks 809 on both sides are rotated 90°, so that the blocks 809 on both sides can be aligned with the grooves at the lower end of the through-hole plate 806, and the vertical rod 805 is loosened. Under the push of the second spring 804, the vertical rod 805 can be moved upward, so that the vertical rod 805 drives the blocks 809 on both sides to engage with the grooves at the lower end of the through-hole plate 806, so that the position of the baffle 803 is fixed, and the position of the crossing frame body 11 is fixed, completing the installation of the crossing frame body 11, and according to the above-mentioned reverse operation, the disassembly of the crossing frame body 11 can be completed.
