Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically a leveling device for building engineering. Background Technology
[0002] Scaffolding is used in construction projects to provide a working platform and safety protection for construction, maintenance, cleaning and other operations. It enables workers to operate at different heights on the building, such as bricklaying, painting, and window installation.
[0003] When scaffolding is in use, the support at the bottom of the scaffolding is erected on the ground, but the ground is usually uneven. Sometimes, shims of different thicknesses are installed at the bottom of the scaffolding to level it. However, there are safety hazards in the leveling process, and the leveling speed is slow and the error is large. Utility Model Content
[0004] The purpose of this utility model is to provide a leveling device for construction engineering, in order to solve the problems mentioned in the background art, that when scaffolding is used, leveling is carried out by building pads of different thicknesses at the bottom of the scaffolding, which poses safety hazards, is slow and has large errors. To achieve the above objectives, this utility model provides the following technical solution: a leveling device for building engineering, comprising a sleeve, a bearing plate fixedly connected to the bottom of the sleeve, a groove on the side surface of the sleeve, a moving component inside the sleeve, the moving component comprising an outer cylinder, the bottom of the outer cylinder fixedly connected to the inner wall of the bottom of the sleeve, a damping rod sleeved on the inner annular surface of the outer cylinder, a bearing plate fixedly connected to one end of the damping rod, an elastic element sleeved on the side surface of the outer cylinder, one side of the bearing plate extending out of the sleeve through the groove, a sliding sleeve fixedly connected to the upper surface of the bearing plate, a connecting plate fixedly connected to the side surface of the sleeve, a gear two sleeved on the side surface of the sleeve, the gear two being disposed on the upper surface of the connecting plate, a lead screw penetrating one side of the connecting plate and a gear one fixedly connected to the extended end, the gear one meshing with the gear two. One end of the lead screw is threaded to one side of the bearing plate two. A connecting column two is fixedly connected to the upper surface of the gear two. A rotating ring is fixedly connected to one end of the connecting column two. A bearing sleeve is fitted onto the side surface of the sliding sleeve. A housing is fixedly connected to the upper surface of the bearing sleeve. A laser light is installed inside the housing. A button is provided on the upper surface of the housing. A scaffolding leg is fitted onto the inner annular surface of the sliding sleeve. This leveling device for construction engineering drives the scaffolding legs to move up and down through the rotation of the lead screw, quickly and stably adjusting the height of the scaffolding. At the same time, the overlap of the laser light beams determines that the scaffolding is in a horizontal state, simplifying the leveling operation process and improving the efficiency of leveling work. By moving the components, the vibration generated by the scaffolding during leveling or use is reduced, reducing vibration caused by external factors or its own structural fine-tuning, and reducing the safety risks caused by scaffolding swaying.
[0005] In a further preferred embodiment, the lead screw is threadedly connected to the portion of the bearing plate two extending from the slot into the sleeve. The other end of the lead screw is fixedly connected to a turntable, and the bottom of the turntable is fixedly connected to the upper surface of the bearing plate one. Two sets of the lead screw, turntable, and gear one are arranged symmetrically. In this leveling device for construction engineering, the lead screw can be rotated by the turntable, and the turntable provides support for the lead screw. By rotating the two sets of lead screws simultaneously, the bearing plate two can be moved, improving the stability of the bearing plate two during movement, reducing damage to the device due to uneven force, and reducing swaying caused by uneven force during scaffolding leveling.
[0006] More preferably, the side surface of the sleeve is provided with scale lines, the scale lines are located on one side of the groove, and the bearing plate extends out of the groove and is fixedly connected to a pointer. This kind of leveling device for construction engineering can quickly adjust the scaffolding by using the height difference data when leveling the scaffolding through the scale lines, reducing the need for repeated leveling and adjustment operations and improving the work efficiency of the workers.
[0007] More preferably, one side of the bearing sleeve is connected to a pin by a thread, the pin passes through the sleeve, and the pin is threaded to the sleeve. This type of leveling device for construction engineering fixes the bearing sleeve by the pin, reducing the displacement of the bearing sleeve due to loosening of the connecting parts between the bearing sleeves, thus reducing errors in the leveling operation.
[0008] More preferably, a fixing component is provided on one side of the pipe sleeve. The fixing component includes a connecting column, one side of which is fixedly connected to the side surface of the pipe sleeve. A slide rail is fixedly connected to one side of the connecting column, and a fixing ring is slidably connected inside the slide rail. A screw passes through one side of the slide rail and passes through the fixing ring. This leveling device for construction engineering uses the fixing component to fix the scaffolding, reducing the risk of the scaffolding becoming unstable and losing balance due to external factors detaching from the device.
[0009] More preferably, the side surface of the pipe sleeve is fixedly connected with stiffening plates, and the upper surface of the bearing plate is connected with fixing bolts by threads. This type of leveling device for construction engineering is fixed to the ground by fixing bolts, which helps to improve the stability of the scaffolding. The stiffening plates further improve the stability of the pipe sleeve.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] In this invention, the rotation of the lead screw drives the scaffold legs to move up and down, quickly and stably adjusting the height of the scaffold. At the same time, the overlap of laser light lines confirms that the scaffold is in a horizontal state, simplifying the leveling operation process and improving the efficiency of leveling work. By moving the components, the vibration generated by the scaffold during leveling or use is reduced, as well as the vibration caused by external factors or its own structural fine-tuning, thus reducing the safety risks caused by scaffold swaying.
[0012] In this invention, the bearing plate II moves by rotating two sets of lead screws simultaneously, improving the stability of the bearing plate II during movement, reducing damage to the device due to uneven force, and reducing swaying caused by uneven force during scaffolding leveling. By using the scale lines, the scaffolding can be quickly adjusted by the known height difference data during leveling, reducing the need for repeated leveling and adjustment operations and improving the work efficiency of workers. The fixing components fix the scaffolding, reducing the risk of the scaffolding detaching from the device due to external factors, which could lead to instability and loss of balance.

A rotating ring 13 is fixedly connected to one end of connecting post 12. A bearing sleeve 14 is fitted onto the side surface of sliding sleeve 8. A housing 16 is fixedly connected to the upper surface of bearing sleeve 14. A laser light 17 is installed inside the housing 16. A button 18 is provided on the upper surface of housing 16. A scaffolding leg 23 is fitted onto the inner annular surface of sliding sleeve 8.
[0022] In this embodiment, as Figure 1 ,and Figure 5 As shown, the lead screw 6 is threadedly connected to the part of the sleeve 1 extending from the slot 4 on the bearing plate 2 304. The other end of the lead screw 6 is fixedly connected to the turntable 5. The bottom of the turntable 5 is fixedly connected to the upper surface of the bearing plate 2. There are two sets of lead screw 6, turntable 5 and gear 10, and their positions are symmetrical.
[0023] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, the side surface of the sleeve 1 is provided with a scale line 20, which is located on one side of the groove 4. The bearing plate 2 304 extends out of the groove 4 and is fixedly connected to a pointer 19.
[0024] In this embodiment, as Figure 1 and Figure 3As shown, a pin 15 is threadedly connected to one side of the bearing sleeve 14. The pin 15 passes through the sleeve 1 and is threadedly connected to the sleeve 1.

The elastic element 303 at the bottom of the bearing plate 2, together with the damping rod 302 and the outer cylinder 301, provides auxiliary support for the bearing plate 2, reducing vibrations generated during scaffolding leveling or use, and lowering the safety risks caused by scaffolding swaying. When leveling the scaffolding, the height difference data can be used to quickly adjust the scaffolding by observing the scale line 20, reducing the need for repeated leveling and adjustment operations and improving the work efficiency of the workers. When the scaffolding leveling is completed, the screw 703 is rotated to make the two fixing rings slide relative to each other in the slide rail 702, fixing the scaffolding legs 23, reducing the risk of the scaffolding detaching from the device due to external factors, which would cause the scaffolding to become unstable and lose balance.
