[0002] During the construction of a building project, construction workers are required to construct the top surface or high walls, so a support device is needed to safely and stably support the construction workers in the construction at high places. The support device has thus become an indispensable and important equipment in the construction process of a building project. After searching, the patent with the authorization publication number of CN220620968U discloses a support device for construction of a building project, including a base, four corners of the bottom end of the base are respectively provided with fixed casters, a standing board is provided on the top of the base, and a lifting cylinder is provided at the middle position of the two sides of the top of the base. By respectively providing a stabilizing structure on one side of the bottom of the movable arm, and then transferring the support device to the construction position of the building project, the adjusting dial is rotated to drive the adjusting lifting column to descend through the threaded connection, and at the same time, the lifting column is limited and stabilized by the limiting sleeve, so as to push the stable bottom plate to stably descend against the ground, so as to achieve the purpose of stabilizing the support device, and further improve the stability of the stable bottom plate after it is against the ground through the anti-slip bottom pad, so as to effectively prevent the device from deviating and causing safety accidents during the construction of the workers on the support device, effectively improve the safety and stability of the support device, and have strong operability. The above patent has the following shortcomings: although the stability of the device is increased to a certain extent through structures such as movable arms, stable base plates and positioning grooves, the supporting force of the movable arms and the stable base plates is only transmitted by the adjustment arms and the positioning grooves, and the support strength needs to be improved. In addition, when in use, multiple movable arms need to be unfolded separately, and multiple adjustment dials need to be rotated separately to drive the stable base plates to contact the ground, which is not convenient. For this reason, we propose a construction engineering support device. Utility Model Content
