Description

Technical Field

[0001] The utility model relates to the technical field of support, in particular to a template support device for construction engineering. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, living, learning, and public activities. In the process of construction engineering, building formwork support devices are needed.

[0003] Existing support technology often uses a building formwork support device for construction projects, such as the one disclosed in announcement number CN216476357U, which makes the positioning plate contact with the ground by turning the crank, and the anti-skid pad increases the friction between the positioning plate and the ground. When the support height of the support plate needs to be adjusted, the hydraulic cylinder drives the support plate to move up and down, and the bolts are tightened until the ends are screwed into the corresponding threaded grooves to fix the support height of the support plate, thereby maintaining the support state for a long time. However, after frequent use of the device, the anti-skid pad will wear out due to long-term friction with the ground, affecting its anti-skid effect. Utility Model Content

[0004] The utility model aims to solve the problem that the fixing device in the prior art is difficult, and proposes a template supporting device for construction engineering.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Preferably, the driving rack and the driven rack are centrally symmetrically arranged on both sides of the transmission gear.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model utilizes a driving motor to drive the worm to rotate, driving the two groups of worm wheels to rotate in opposite directions, and uses the central axis to pull the free end of the connecting rod to slide in the support column, thereby driving the sliding column to slide upward, and the four groups of sliding columns move synchronously, so that the support plate remains stable during the lifting process.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0023] The lifting mechanism includes a worm 10 matched with the output end of the driving motor 4, two sets of central shafts 11 penetrating the outer side of the first shaft seat 2 are movably installed between the first shaft seat 2 and the second shaft seat 3, and a worm wheel 12 meshing and connected with the worm 10 is fixedly installed on the central shaft 11. The rotation of the worm 10 will drive the two sets of worm wheels 12 to rotate in opposite directions. The free ends of the two sets of central shafts 11 are fixedly installed with connecting rods 13 for movable traction support sliding columns 6. The rotation of the worm wheel 12 will synchronously drive the connecting rod 13 to deflect, so that the support plate 7 remains stable during the rising process. The connecting rod 13 is slidably mounted in the lower end of the sliding column 6, and a traction long hole 1301 is opened in the connecting rod 13. The lower end of the sliding column 6 is integrally connected with a traction long bolt 601 slidably mounted in the traction long hole 1301. The bottom end of the sliding column 6 is matched with a universal wheel 14. When the device is in the storage state, it can be moved by the universal wheel 14.

[0024] The lifting mechanism further includes a fixing device which is arranged through the second cavity 9 and is used to fix the base 1 .

[0025] The fixed tooling includes a driving rack 15 slidably installed in the second cavity 9 and fixedly connected to the sliding column 6, a driven rack 16 is slidably installed in the second cavity 9, and a transmission gear 17 meshing and connected with the driving rack 15 and the driven rack 16 is rotatably installed in the second cavity 9.

When the sliding column 6 rises, the driving rack 15 will rise with the sliding column 6, and the universal wheel 14 will be received in the first cavity 8. At this time, the driven rack 16 will slide downward through traction by the transmission gear 17, and the cone column 18 will therefore contact the ground, thereby stably fixing the device on the ground.

[0026] It should be noted that the specific model and specifications of the drive motor 4 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.
