Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a jacking device for quickly fixing a pressure sensor. Background Art

[0002] During construction on site, in order to ensure the safety of construction workers, the pressure that the scaffolding can withstand is detected to prevent the scaffolding from collapsing due to excessive pressure and causing major accidents. Existing scaffolding will install a pressure detection sensor on the top support and then hold the scaffolding to detect the pressure. For example, CN212406065U discloses a scaffolding top support pressure limiting device, including a tray with a pressure sensor installed in the tray. Its characteristics are: it can detect and adjust the pressure of the scaffolding top support in real time during use, so as to achieve the effect of improving personnel safety. Its disadvantage is that the installation of the pressure detection sensor on the existing top support mostly uses multiple bolts for connection and fixing, which is cumbersome to install and disassemble.

[0022] Embodiment 1:

[0023] See also Figure 1-4 A supporting device for quickly fixing a pressure sensor comprises a supporting rod 10, a supporting plate 20 is fixedly mounted on one end of the supporting rod 10, a movable adjustment component is movably and adjustably mounted on the supporting rod 10, at least two limit frames 60 are mounted on the movable adjustment component, and the limit frames 60 extend above the supporting plate 20, and a limit column 61 is arranged on one side of the limit frame 60 facing the upper side of the supporting plate 20. The supporting rod 10 is used to support the supporting plate 20, and the movable adjustment component can move and change positions along the supporting rod 10, and adjust the position of the limit frame 60, see Figure 1 When the movable adjustment assembly moves upward, it is convenient to place the pressure sensor 70 on the support plate 20, see Figure 4 When the movable adjustment assembly moves downward, the limit frame 60 is driven to move downward, and the limit column 61 on the lower side of the limit frame 60 is inserted into the mounting hole of the pressure sensor 70, thereby limiting and fixing the pressure sensor 70. Through the above structure, it is more convenient to install and remove the pressure detection sensor on the top support.

[0024] In one of the schemes, see Figure 1 The movable adjustment component includes a lifting plate 40, a limiting frame 60 is installed on the lifting plate 40, a limiting component 50 is installed on the lower side of the lifting plate 40, and the support rod 10 is a screw rod. A nut sleeve 30 is movably screwed on the support rod 10. The nut sleeve 30 is located at the lower side of the lifting plate 40 and is limited by the limiting component 50 with the lifting plate 40. By screwing the nut sleeve 30, the lifting plate 40 is driven to move, thereby driving the limiting frame 60 to move.

[0025] For details, see Figure 1 The limiting assembly 50 is two opposite L-shaped plates.

[0026] Of course, in addition to the above-mentioned structure, the movable adjustment component can also adopt other structures, such as connecting the top of the nut sleeve 30 with the lifting plate 40 for rotation and limiting, that is, the lifting plate 40 and the groove on the outer wall of the upper end of the nut sleeve 30 are connected for rotation and matching for limiting. In this way, when the nut sleeve 30 is screwed, the lifting plate 40 will not rotate, but will also move up and down with the nut sleeve 30.

[0027] Embodiment 2:

[0028] Based on Example 1, see Figure 1 , 2The lifting plate 40 is provided with first slide grooves 41 on both the front and rear sides, the limiting frame 60 is a door frame structure, and the limiting frame 60 is provided with protrusions 63 on both sides connected with the lifting plate 40, and the protrusions 63 are connected with the first slide grooves 41 in a sliding guide. With the above structure, the limiting frame 60 can be moved, which makes it easier to place the pressure sensor 70 on the support plate 20.

[0029] See also Figure 1 When in use, the nut sleeve 30 is screwed to raise the lifting plate 40 a short distance, and then the limiting frame 60 is moved outward, the pressure sensor 70 is placed on the support plate 20, and then the limiting frame 60 is reset, and the positions of the limiting frame 60 and the pressure sensor 70 are adjusted to make the limiting column 61 align with the mounting hole on the pressure sensor 70, and then the nut sleeve 30 is screwed in the opposite direction until the limiting column 61 enters the mounting hole on the pressure sensor 70, and the limiting frame 60 presses the mounting plate of the pressure sensor 70. Since the limiting frame 60 is against the edge of the support plate 20, and the lifting plate 40 is rotatably connected with the nut sleeve 30, when the nut sleeve 30 is rotated, the lifting plate 40 will not rotate with the nut sleeve 30.

[0030] In another embodiment, the front and rear sides of the lifting plate 40 are respectively provided with first slide grooves 41, the limiting frame 60 is in an L-shaped structure, and the side where the limiting frame 60 is connected to the lifting plate 40 is respectively provided with a protrusion 63, and the protrusion 63 is connected with the first slide groove 41 for sliding guidance. In order to prevent the L-shaped limiting frame 60 from falling, the cross section of the first slide groove 41 can be a "convex" shaped structure, and the protrusion 63 slides with the first slide groove 41 in cooperation with the guidance.

[0031] Furthermore, a second slide groove 62 is provided on one side of the limit frame 60 facing the upper side of the support plate 20, and a limit portion 611 is provided on one end of the limit column 61 connected to the limit frame 60, and the limit column 61 slides and adjusts in the second slide groove 62 through the limit portion 611. Since the positions of the mounting holes of the pressure sensors 70 of different sizes are different, the movement and adjustment of the limit column 61 can be realized through the above structure. This facilitates the installation of pressure sensors 70 of different sizes. For details, see Figure 1 The cross section of the second slide groove 62 is a "convex" shaped structure.

[0032] Furthermore, a plurality of limiting holes 21 are provided on the side of the support plate 20 facing the limiting column 61. Figure 2 When installing the pressure sensor 70 , the limiting column 61 passes through the installation hole on the pressure sensor 70 and then passes into the limiting hole 21 , so that the installation of the pressure sensor 70 is more stable.

[0033] The working principle or action process of the utility model is as follows:

[0034] When using, see Figure 1When installing the pressure sensor 70, first screw the nut sleeve 30 to raise the lifting plate 40 a short distance, and the limit frame 60 rises accordingly, ensuring that the limit column 61 does not interfere with the mounting plate of the pressure sensor 70. Then move the limit frame 60 outward, place the pressure sensor 70 on the support plate 20, and then reset the limit frame 60, adjust the positions of the limit frame 60 and the pressure sensor 70, and make the limit column 61 align with the mounting hole on the pressure sensor 70 and the limit hole 21.

[0035] Afterwards, see Figure 4 , screw the nut sleeve 30 in the opposite direction until the limiting column 61 enters the mounting hole on the pressure sensor 70 and the limiting hole 21 on the support plate 20, and the limiting frame 60 presses the mounting plate of the pressure sensor 70, thereby completing the installation of the pressure sensor 70.

[0036] When disassembling the pressure sensor 70 , the above operation can be reversed to conveniently disassemble the pressure sensor 70 .
