[0002] A truck crane is a type of crane installed on an ordinary car chassis or a special car chassis, with its driving cab and lifting control cab separately arranged. The advantages of this type of crane are good maneuverability and rapid transfer. The disadvantages are that it requires outriggers when working, cannot travel under load, and is not suitable for working on soft or muddy grounds. The chassis performance of a truck crane is equivalent to that of a truck with the same gross vehicle weight, and meets the technical requirements of road vehicles, so it can travel unimpeded on all types of roads. This type of crane is generally equipped with two control cabs for getting on and off the vehicle, and the outriggers must be extended to maintain stability during operation. Truck cranes are often used to hoist various beams, such as T-beams, but traditional truck cranes find it difficult to keep the beam level when hoisting T-beams, and manual monitoring of the stability of the support points of the truck crane is required.

[0027] Example: See Figure 1As shown, an embodiment of a prefabricated T-beam erection device based on a truck crane and a double-trolley crane is shown, wherein the erection device includes a truck crane 1; an anemometer 8 arranged on the boom 2 of the truck crane 1; a force sensor 9 connected to the support arm 3 of the truck crane 1; an alarm light 10 arranged on the truck crane 1 and electrically connected to the anemometer 8 and the force sensor 9; a lifting rope 4 connected to the top of the boom 2; a hook 5 arranged at the end of the lifting rope 4; and a tension sensor 7 fixed on the hook 5.

[0028] In this embodiment, the anemometer 8, the force sensor 9, the tension sensor 7 and the alarm light 10 are all electrically connected to the background controller (not shown). The anemometer 8 is used to measure the wind speed when the mobile crane 1 is in operation. The force sensor 9 is used to monitor the real-time overturning force of the mobile crane 1. The tension sensor 7 is used to measure the real-time tension of the hook 5 when the mobile crane 1 is in operation.

[0029] In this embodiment, both the anemometer 8 and the force sensor 9 are provided with a minimum trigger threshold.

[0030] In this embodiment, the number of the support arms 3 is two groups of four in total, which are symmetrically arranged at the front and rear of the vehicle crane 1 , and the force sensor 7 is arranged on the support foot 31 of the support arm 3 .

[0031] In this embodiment, it also includes a steel wire rope 4 which is hung at the center of the T-beam 6 by a bag hanging method and is connected to the hooks 5 on the left and right.

[0032] In this embodiment, there are two erection devices, and they are respectively hung at the symmetrical two ends of the T-beam 6 through their own steel wire ropes 4 and connected to the corresponding hooks 5 respectively.

[0033] The characteristics and functions of the present invention can be further understood through the following description.

[0034] The erection device of this embodiment is mainly used to monitor various real-time data of the mobile crane 1 in real time to ensure the stability of the mobile crane 1 during operation. The main working method is as follows:

[0035] join Figure 1 and Figure 2 As shown, in this embodiment, two truck cranes 1 are used to erect the prefabricated T-beam 6 .

[0036] Two steel wire ropes 4 are used at both ends of the T-beam 6 for lifting by the scoop hanging method, and the lifting points on both sides are symmetrical about the center of the T-beam 6; tension sensors 7 are installed on the hooks 5 of the automobile crane 1, and the tension sensors 7 are used to measure the tension at the hooks 5 in real time and display it on the terminal platform (i.e., the background controller).

[0037] Adjust the lifting heights of the two truck cranes 1 according to the value displayed by the tension sensor 7, so that the values ​​of the two tension sensors 7 remain consistent, ensuring that the T-beam 6 is in a horizontal state during the lifting process: if the value of the tension sensor 7 is too large, it means that the height of the lifting point is too high, and the height of the boom 2 should be appropriately lowered at this time; if the value of the tension sensor 7 is too small, it means that the height of the lifting point is too low, and the height of the boom 2 should be appropriately raised at this time.

[0038] A force sensor 9 is arranged on the support arm 3 of the mobile crane 1 to monitor the real-time overturning force of the mobile crane 1; an anemometer 8 is arranged on the arm 2 to measure the wind speed during construction, and an alarm light 10 connected to the force sensor 9 and the anemometer 8 is arranged on the vehicle. Under normal circumstances, the alarm light 10 is off. When the overturning force or wind speed exceeds the limit, an alarm is issued, wherein the overturning alarm is a flashing red light, and the wind speed alarm is a constant red light. This ensures the safety of construction.

[0039] When the beam is dropped, the two suspension points can be controlled to drop the beams simultaneously according to the readings of the tension sensors 7 arranged at the suspension points, so as to avoid problems such as beam body deviation caused by asynchronous beam dropping.

[0040] In summary, the utility model uses two steel wire ropes at each end of the T-beam and lifts it through the bag hanging method, measures the real-time tension of the hook during the construction of the truck crane through a tension sensor, monitors the real-time overturning force of the truck crane through a force sensor, and measures the wind speed during the construction of the truck crane through a wind speed meter, and at the same time monitors the T-beam in real time to ensure the stability of the T-beam during the lifting process.

[0041] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
