[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments. Example

[0021] See also Figures 1 to 4 The embodiment of the utility model provides a prestressed frame beam top support adjustment device, which includes: a base plate 1, a top plate 2, a sliding seat 3, a jacking mechanism 4 and a limiting component 5.

[0022] The base plate 1 is symmetrically mounted with slide rails 11, and the four corners of the base plate 1 are welded with support sleeves 12. The four support sleeves 12 are slidably mounted with support rods 13, and the top ends of the four support rods 13 are commonly mounted with a top plate 2;

[0023] A plurality of sliding seats 3 are provided, and the plurality of sliding seats 3 are slidably mounted on the two slide rails 11, and a jacking mechanism 4 is mounted on the plurality of sliding seats 3, and the jacking mechanism 4 comprises a main hydraulic rod 41, and two groups of main hydraulic rods 41 are symmetrically mounted on the sliding seat 3, and the telescopic ends of the two groups of main hydraulic rods 41 are jointly mounted with an intermediate plate 42, and a limiting component 5 is mounted on the intermediate plate 42, and a cross positioning block 43 is fixedly mounted on the top of the intermediate plate 42, and a plurality of positioning grooves 201 that are plugged and matched with the cross positioning block 43 are evenly opened at the bottom end of the top plate 2;

[0024] Among them, the limiting assembly 5 includes a limiting plate 51, a limiting sleeve 52 and a two-way hydraulic rod 53. The limiting plate 51 is fixedly installed at the bottom end of the middle plate 42, and an installation cavity 503 is opened at the bottom end of the limiting plate 51, and a two-way hydraulic rod 53 is installed in the installation cavity 503. The limiting sleeve 52 is fixedly installed on the sliding seat 3 and wraps the two main hydraulic rods 41 therein, and a sliding groove 501 that slides with the limiting plate 51 is opened on the limiting sleeve 52. A plurality of limiting holes 502 are evenly opened on both sides of the sliding groove 501 on the limiting sleeve 52, and the two telescopic ends of the two-way hydraulic rod 53 pass through the through hole opened in the limiting plate 51 and are plugged into the limiting hole 502.

[0025] It should be noted that: when in use, the base plate 1 is fixed on the floor slab, and then several sliding seats 3 are driven to slide along the two slide rails 11 until they are adjusted to the appropriate support point position, and then the cross positioning block 43 is used to plug and position with the positioning groove 201 of the top plate 2, and then the main hydraulic rod 41 is started to lift the top plate 2 through the middle plate 42, so that the top plate 2 contacts the bottom end of the frame beam and lifts the frame beam, and then during the lifting movement, the middle plate 42 synchronously drives the limit plate 51 to slide along the slide groove 501, and when it is lifted to the set position, the two-way hydraulic rod 53 is controlled to extend, and the telescopic ends at both ends are inserted into the corresponding limit holes 502, thereby completing the position locking of the middle plate 42, which can effectively prevent the middle plate 42 from being under a large load, causing the piston rod of the main hydraulic rod 41 to deform, thereby causing damage to the main hydraulic rod 41.

[0026] In the present embodiment, four groups of limit plates 51 are provided, and the four groups of limit plates 51 are distributed in a circle based on the axis of the middle plate 42. Four slide grooves 501 are also provided correspondingly, and the four slide grooves 501 are distributed in a circle based on the axis of the limit sleeve 52. In this way, the four groups of limit plates 51 are used to limit and support the middle plate 42, so that the limit support can be more firm and stable.

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 Adjustment hydraulic rods 14 are fixedly installed at the four corners of the base plate 1, a level 15 is embedded in the middle of the upper surface of the base plate 1, and a side plate 16 is installed on one side of the base plate 1 by screws, and a plurality of mounting grooves 101 are opened on the side plate 16.

[0028] It should be noted that: when installing the base plate 1, place it on the floor, then adjust the hydraulic rods 14 at the four corners until the level 15 is in a horizontal state, and then use anchor bolts to pass through the installation groove 101 opened in the side plate 16 and fix it to the side wall of the floor, thereby completing the overall installation of the base plate 1 and ensuring that the main hydraulic rod 41 can support and lift vertically. Example

[0029] This second embodiment is based on the first embodiment. Figure 1 and Figure 5 A secondary hydraulic rod 6 is embedded at the bottom end of the sliding seat 3 , the telescopic end of the secondary hydraulic rod 6 faces one side of the base plate 1 , and a through groove 102 is opened below the secondary hydraulic rod 6 on the base plate 1 .

[0030] It should be noted that when the jacking mechanism 4 on the multiple sliding seats 3 is used to jack up the frame beam, the piston end of the auxiliary hydraulic rod 6 is synchronously controlled to extend and pass through the through groove 102 to contact the floor slab, thereby providing auxiliary support for the sliding seat 3 to avoid deformation of the base plate 1 caused by the pressure on the entire sliding seat 3, which would affect the overall support jacking.

[0031] The working principle of the prestressed frame beam top support adjustment device provided by the utility model is as follows:

[0032] When in use, the base plate 1 is fixed on the floor slab, specifically, it is placed on the floor slab, and then the adjusting hydraulic rods 14 at the four corners are adjusted until the level 15 is in a horizontal state, and then the anchor bolts are passed through the mounting grooves 101 opened in the side plates 16 to fix it to the side walls of the floor slab, thereby completing the overall installation of the base plate 1, and then the plurality of sliding seats 3 are driven to slide along the two slide rails 11 until they are adjusted to a suitable support point, and then the cross positioning block 43 is plugged into the positioning groove 201 of the top plate 2 for positioning, and then the main hydraulic rod 41 is started to pass through the mounting grooves 101 of the top plate 20 ... The top plate 2 is lifted up through the middle plate 42, so that the top plate 2 contacts the bottom end of the frame beam and lifts the frame beam. Then, during the lifting process, the middle plate 42 synchronously drives the limit plate 51 to slide along the slide groove 501. When it is lifted to the set position, the two-way hydraulic rod 53 is controlled to extend, and the telescopic ends at both ends are inserted into the corresponding limit holes 502, so as to complete the position locking of the middle plate 42, which can effectively prevent the middle plate 42 from causing the piston rod of the main hydraulic rod 41 to deform under a large load, thereby causing damage to the main hydraulic rod 41.

[0033] At the same time, the piston end of the auxiliary hydraulic rod 6 is controlled to extend and pass through the through slot 102 to contact the floor slab, thereby providing auxiliary support to the sliding seat 3 to prevent the entire sliding seat 3 from being compressed and causing deformation of the base plate 1, thereby affecting the overall support lifting.

[0034] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
