[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0024] See also Figure 1-4In the utility model, a vehicle-mounted lifting system for municipal construction includes a base 1 fixed on a car, a lifting frame 2 is rotatably mounted on the base 1, a retractable motor 3 is fixedly mounted on the lifting frame 2, a transmission is fixedly mounted on the output shaft of the retractable motor 3, and a winding wheel 4 is fixedly mounted through the output shaft of the transmission, a lifting steel rope 5 is fixedly connected to the winding wheel 4, a lower guide tube 6 is integrally formed on the lifting frame 2, a guide rod 7 slidably connected to the lower guide tube 6 is sleeved, the other end of the lifting steel rope 5 passes through and extends to the bottom of the guide rod 7, one end of the lifting steel rope 5 located at the bottom of the guide rod 7 is rotatably connected to a lifting hook 8, the lifting hook 8 is mounted on the bottom end of the guide rod 7, and a positioning pin 9 is installed at the connection between the lifting hook 8 and the guide rod 7.

[0025] In the utility model, according to the tools or hoisting environment required for hoisting during municipal construction, the hoisting hook 8 is divided into two hoisting modes: first, the hoisting hook 8 is detached from the bottom of the guide rod 7, and the hoisting hook 8 is only pulled up by the hoisting steel rope 5. At this time, the equipment hoisted on the hoisting hook 8 has a larger movable space, which is convenient for personnel to assist in the hoisting and moving process of the equipment; second, the hoisting hook 8 is installed and fixed to the bottom of the guide rod 7, and the restriction between the guide rod 7 and the lower guide tube 6 is loosened to facilitate the relative sliding of the guide rod 7 and the lower guide tube 6. At this time, the equipment hoisted on the hoisting hook 8 is restricted by the guide rod 7 and the lower guide tube 6 and cannot shake or the shaking amplitude is reduced, so that the hoisting system can more accurately place or lift the hoisted equipment, thereby improving the stability of the equipment during the hoisting process; this solution can adopt corresponding rigid hoisting or flexible hoisting methods according to the equipment and environmental requirements of municipal construction, thereby ensuring the stability or adjustability of the hoisted equipment and improving the hoisting efficiency of the equipment.

[0026] See also Figure 1 , wherein: two guide wheels 10 are fixedly installed inside the lifting frame 2, and the lifting steel rope 5 is located between the two guide wheels 10.

[0027] In the utility model, the two guide wheels 10 can limit the lifting rope 5 between the two, avoid contact and friction between the lifting rope 5 and the inner wall of the lifting frame 2, reduce the wear of the lifting frame 2 and the lifting rope 5, and at the same time notify the smoothness of the retraction and release of the lifting rope 5.

[0028] See also Figure 1 and Figure 3 , wherein: a limiting screw 71 is threadedly connected to the guide rod 7 , an annular limiting groove 61 is opened on the lower guide tube 6 , and one end of the limiting screw 71 extends to the inner side of the annular limiting groove 61 .

[0029] In the utility model, the relative sliding of the guide rod 7 and the lower conduit 6 can be limited by limiting the cooperation between the limiting screw 71 and the annular limiting groove 61. When the limiting screw 71 is disengaged from the annular limiting groove 61, the guide rod 7 can slide up and down on the lower conduit 6.

[0030] See also Figure 1 and Figure 4 , wherein: the bottom of the guide rod 7 is rotatably connected to a sliding block 72, the top of the lifting hook 8 is T-shaped and slidably connected to the sliding block 72, and the positioning pin 9 is inserted into the socket between the lifting hook 8 and the sliding block 72.

[0031] In the utility model, the lifting hook 8 can be installed on the bottom of the guide rod 7 by the T-shaped docking of the sliding block 72 and the top of the lifting hook 8, and fixed by the positioning pin 9 to prevent the lifting hook 8 from detaching.

[0032] See also Figure 1 , wherein: the shape of the hanging frame 2 is L-shaped, and a reinforcing rod 21 is fixedly installed at the corner outside the hanging frame 2.

[0033] In the utility model, the L-shaped hoisting frame 2 is convenient for hoisting equipment used in municipal construction and is easy to use on a vehicle, while the reinforcing rod 21 improves the load-bearing capacity of the hoisting frame 2 .
