Abstract
Description
Technical Field
[0001] The utility model relates to a device for tightening nuts on vertical prestressed threaded steel bars. Background Art
[0002] In construction projects, vertical prestressed threaded steel bars are a commonly used structural reinforcement material, and nuts need to be tightened during their installation. However, traditional nut tightening methods mainly rely on manual operation, which not only has low efficiency but also makes it difficult to control the tightening force, easily leading to nut loosening and affecting the project quality. Moreover, the nut is located below the plane, making it very inconvenient and inefficient to tighten during the process. Content of the Utility Model
[0003] The utility model solves the deficiencies existing in the prior art and provides a device for tightening nuts on vertical prestressed threaded steel bars.
[0004] The technical solution adopted by the utility model is as follows: A device for tightening nuts on vertical prestressed threaded steel bars, comprising a driving device for pulling the threaded steel bar, the upper end of the threaded steel bar is connected to the driving device, and a plurality of guide columns are connected to the lower end of the driving device. Each guide column is slidably connected to a sliding sleeve, and the sliding sleeve is fixedly connected to a mounting plate. The mounting plate is rotatably connected to a gear, and the gear is meshed and driven by a motor. The gear is connected to a sleeve, and the motor drives the gear to drive the sleeve to rotate through the gear. The upper and lower ends of the sleeve are through, and the threaded steel bar passes through the sleeve.
[0005] Among them, the driving device is a hollow oil cylinder.
[0006] Among them, the sliding sleeve includes a linear bearing.
[0007] Among them, the lower end of the guide column is fixedly connected to a bottom plate, and a through hole for the threaded steel bar to pass through is provided on the bottom plate.
[0008] Compared with the prior art, the beneficial effect of the utility model lies in: Description of the Drawings
[0009] Figure 1 It is a structural schematic diagram of the utility model. Detailed Embodiment
[0010] The following further illustrates the utility model in conjunction with the drawings and through embodiments.
[0011] Such as Figure 1As shown in the figure, in this embodiment, a device for tightening nuts on vertical prestressed threaded steel includes a driving device 1 for pulling the threaded steel 2. As a preferred embodiment, the driving device 1 is a hollow oil cylinder. The upper end of the threaded steel 2 is connected to the driving device 1, and a plurality of guide columns 3 are connected to the lower end of the driving device 1. Each guide column 3 is slidably connected to a sliding sleeve 4, and the sliding sleeve 4 is fixedly connected to a mounting plate 5. The mounting plate 5 is rotatably connected to a gear 6. Hole positions 50 are respectively provided in the middle of the gear 6 and the mounting plate 5. The gear 6 is driven by a motor 7 in a meshing manner. The gear 6 is connected to a sleeve 9. The motor 7 drives the gear 6 to drive the sleeve 9 to rotate through the gear 6. The upper and lower ends of the sleeve 9 are through, and the threaded steel 2 passes through the sleeve 9. In this embodiment, the operator passes the threaded steel 2 vertically through the device. A first nut 8 can be screwed on the upper end of the threaded steel 2 to be connected to the driving device 1. When the driving device 1 extends, it can pull the threaded steel 2. Below the first nut 8, a second nut is also screwed on the threaded steel 2. After the driving device 1 lifts the threaded steel 2, the sleeve 9 is sleeved on the second nut, and the motor 7 drives the sleeve 9 to rotate to screw the second nut.
[0012] As a preferred embodiment, the sliding sleeve 4 includes a linear bearing.
[0013] As a preferred embodiment, the lower end of the guide column 3 is fixedly connected to a bottom plate, and a through hole for the threaded steel 2 to pass through is provided on the bottom plate.
