Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a detachable soil excavation hanging frame applicable to municipal pipe jacking construction by improvement. The technical solution of the present invention is as follows:

[0026] As Figures 1 to 5 shown, the embodiment of the present invention provides a detachable soil excavation hanging frame applicable to municipal pipe jacking construction, including a pair of front steel piers 1 and rear steel piers 2. The ends of the pair of front steel piers 1 and rear steel piers 2 are both fixedly installed with a main cross beam 5 in common. The surface of the pair of main cross beams 5 is fixedly installed with an operating platform 6 in common. A plurality of first support scaffolds 3 and second support scaffolds 4 are arranged at the bottom of the operating platform 6. A support back rib 17 is fixedly installed in common between every three adjacent first support scaffolds 3 and second support scaffolds 4 and the operating platform 6. It further includes a lifting assembly. By arranging the front steel piers 1 and rear steel piers 2 in cooperation with the support scaffolds, not only can stable support be provided for the whole device, but also reasonable adjustment can be made according to the conditions of the construction ground, greatly improving the adaptability of the device.

[0027] The lifting assembly is arranged on the surface of the operating platform 6.

[0028] The lifting assembly includes two pairs of support frames 7 fixedly installed on the operation platform 6. On the surface of each pair of support frames 7, a support crossbeam 8 is fixedly installed through bolts. The provided support crossbeam 8 can provide a stable installation foundation for subsequent lifting components and ensure the normal operation of the lifting components.

[0029] Furthermore, a longitudinal beam support frame 9 is fixedly installed on the surface of a pair of support crossbeams 8. Limit plates 10 are fixedly installed at both ends of the longitudinal beam support frame 9. A walking beam 11 is fixedly installed between a pair of limit plates 10. An electric hoist 15 is arranged on the walking beam 11. The limit plates 10 improve the stability of the movement of the electric hoist 15. The provided walking beam 11 can not only provide support for the installation of the electric hoist 15 but also provide support for its reciprocating movement.

[0030] Furthermore, a first reinforcing rod 18 is fixedly welded between both sides of the support crossbeam 8 and the walking beam 11. A pair of second reinforcing rods 19 are fixedly welded between the opposite sides of each support frame 7 and the support crossbeam 8. The provided first reinforcing rod 18 and second reinforcing rods 19 can greatly improve the overall structural strength of the device, greatly improve the overall stability, and thus ensure the stable safety during the lifting process.

[0031] Furthermore, an extension frame 14 is fixedly installed on one side of the limit plate 10 at the front end. A third reinforcing rod 20 is fixedly installed between one side of the support frame 7 at the front end and the extension frame 14. The third reinforcing rod 20 can further improve the structural strength between the support frame 7 and the walking beam 11, and thus improve the stability of the operation of the electric hoist 15.

[0032] Furthermore, a counterweight 12 is arranged on one side of the operation platform 6. A cable 13 is fixedly installed between the counterweight 12 and the rear end of the walking beam 11. By providing the counterweight 12 and the cable 13, the phenomenon of weight imbalance at both ends of the device during lifting can be avoided, and the stable safety during the lifting process can be greatly improved.

[0033] Specific working principle: During the construction of the excavation lifting frame, first, use machinery to level the site, and weld the truss structure of the entire lifting frame in the site. When welding, the weld length and height are carried out according to the requirements of the drawings; at the same time, cut the front steel pier 1, rear steel pier 2 and main crossbeam 5 of the lifting frame according to the designed length. After the welding of the entire support system and lifting system structure of the lifting frame is completed, it is integrally hoisted onto the already hoisted main crossbeam 5 and fixed as a whole by anchor bolt connection. Finally, an operation platform 6 is fixedly installed between the two main crossbeams 5 for the convenience of later construction personnel to operate, and a safety protection fence 16 is installed around the operation platform 6 for protection. After the installation of the entire excavation lifting frame is completed, organize inspection and acceptance. After passing the acceptance, conduct a trial lift, and it can be put into use only after the trial lift is qualified.
