[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a pipeline hoisting device for petrochemical construction, comprising a hoisting truss 1 and a lower hanging mechanism 4, and the lower hanging mechanism 4 is arranged on both sides of the hoisting truss 1;

[0019] The lower hanging mechanism 4 includes a fixed plate 41, which is fixedly connected to the top of the lifting truss 1. An electro-hydraulic push rod 42 is installed on the top of the fixed plate 41 away from the lifting truss 1. The telescopic end of the electro-hydraulic push rod 42 moves through the fixed plate 41 and is fixedly connected to a travel block 43. The other end of the travel block 43 is fixedly connected to an extension rod 45. A servo motor 46 is installed on the top of the extension rod 45 through a fixed frame. The output end of the servo motor 46 is fixedly connected to a rotating shaft 47 through a coupling. The other end of the rotating shaft 47 moves through the extension rod 45 and is fixedly connected to a cross bar 48. The cross bar 48 is rotatably connected to the bottom of the extension rod 45.

[0020] Rollers 3 are installed at the four corners of the bottom of the lifting truss 1 through the pin shaft 2. The rollers 3 are rotatably sleeved on the shaft wall of the pin shaft 2, and the pin shaft 2 is plugged into the outer wall of the lifting truss 1. The rollers 3 can effectively make the lifting truss 1 more convenient when sliding.

[0021] The servo motor 46 is electrically connected to an external power supply through a PLC controller. The TB6600 PLC controller can effectively control the speed and direction of the servo motor 46 .

[0022] A limit rod 44 is inserted into the position of the travel block 43 corresponding to the top of the lifting truss 1, and the limit rod 44 passes through one end of the lifting truss 1 and moves through the travel block 43. The setting of the limit rod 44 can effectively make the travel block 43 more stable during lifting.

[0023] The length of the cross bar 48 is smaller than the width of the hoisting truss 1, which can effectively ensure that the cross bar 48 can be turned over normally.

[0024] Specifically, when using the utility model, the conveying pipeline to be installed is placed on the two cross bars 48 inside the two groups of lower hanging mechanisms 4 in the lifting truss 1. The cross bars 48 can support the pipeline, and then the lifting truss 1 can be pushed to move to the pit for construction. When the pipeline is aligned with the pit, the electro-hydraulic push rod 42 is started to drive the travel block 43 to move vertically downward along the limit rod 44. When moving, the travel block 43 can drive the cross bar 48 to move accordingly through the extension rod 45, and the cross bar 48 drives the conveying pipeline to be lifted to the inner bottom of the pit. When the bottom of the cross bar 48 contacts the inner bottom wall of the pit, the servo motor 46 can be started, and the output end of the servo motor 46 drives the cross bar 48 to rotate, so that the cross bar 48 deviates from the bottom of the conveying pipeline and moves to one side of the conveying pipeline. The cross bar 48 is separated from the conveying pipeline. At this time, the electro-hydraulic push rod 42 can drive the cross bar 48 to extend upward for reset.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
