[0020] In order to better understand the purpose, structure and function of the present utility model, the following further detailed description of the present utility model is made with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0021] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by the terms "horizontal", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0022] As Figures 1 to 4As shown in the figure, the present utility model provides a simple transverse sliding device for a beam body, which includes a pair of sliding tracks 3 symmetrically arranged along the transverse direction of the beam body 1 and a pair of sliding mechanisms symmetrically arranged on the pair of sliding tracks 3. The beam body 1 is symmetrically located on the pair of sliding tracks 3. The sliding mechanism includes a jack 8, a limiting box 6 surrounding the outer periphery of the jack 8, and a pair of connecting beams 4 connected to the limiting box 6. One side of the jack 8 facing the beam body 1 is limited by a limiting block 5 fixed on the sliding track 3, and the opposite side tightly abuts against and connects to the inner wall of the limiting box 6. An opening larger than the size of the limiting block 5 is arranged on the side of the limiting box 6 facing the beam body 1. The pair of connecting beams 4 and the beam body 1 are detachably connected by bolts 9.

[0023] The outer shell of the jack 8 is limited and fixed by the limiting block 5 and does not slide, while the telescopic rod of the jack 8 tightly abuts against and connects to the inner wall of the limiting box 6. When the jack 8 expands and contracts, it pushes the limiting box 6 to slide along the sliding track 3, and then drives the connecting beam 4 to drive the beam body 1 to slide along the sliding track 3, thereby realizing the transverse sliding of the beam body 1. The pair of sliding mechanisms are completely the same and the installation positions are also exactly the same, and the synchronous expansion and contraction actions are controlled by the same control system. The bolt 9 passes through the reserved bolt holes of the beam body 1 and the bolt holes of the connecting beam 4 for limiting and fixing. As Figure 2 shown, the solid line part is the original position 1-1 of the beam body, and the dotted line part is the required position 1-2 after the beam body slides along the sliding track 3.

[0024] In another technical solution, a plurality of pairs of bolt holes are arranged on the pair of connecting beams 4 along their length directions in a one-to-one correspondence, and bolt holes are also reserved on the beam body 1. The pair of connecting beams 4 are inserted into the beam body 1, and any pair of bolt holes on the pair of connecting beams 4 correspond to the bolt holes on the beam body 1 and are connected by bolts 9.

[0025] The connecting beam 4 and the beam body 1 are detachably connected by bolts 9. When the jack 8 drives the beam body 1 to move until the stroke of the jack 8 reaches the maximum, the connection between the connecting beam 4 and the beam body 1 is released, the jack 8 is driven to retract, and the limiting box 6 and the connecting beam 4 are driven to retreat in the opposite direction of the movement of the beam body 1. At this time, the connecting beam 4 and the beam body 1 move relatively until the next pair of bolt holes of the connecting beam 4 cooperate with the beam body 1. At this time, the connecting beam 4 and the beam body 1 are connected again by bolts 9, and the above-mentioned action of the jack 8 extending to drive the beam body 1 to slide is repeated. The above actions are repeated in sequence until the beam body 1 slides to the set position.

[0026] In another technical solution, a tetrafluoroethylene slide plate is arranged on the top surface of the sliding track 3, and the beam body 1 is located on the tetrafluoroethylene slide plate. The material of the sliding track 3 is selected as a material with a relatively small friction coefficient, such as I-beam, etc. The tetrafluoroethylene slide plate can further reduce the friction force between the beam body 1 and the sliding track 3.

[0027] In another technical solution, a pair of sliding tracks 3 are fixedly arranged on the support system 2, and the support system 2 is a fixed three-dimensional frame structure. By fixedly arranging the sliding tracks 3 through the support system 2, the falling of the sliding tracks 3 is prevented. The support system 2 can also be arranged as a pair of fixed supports, with a pair of sliding tracks 3 fixedly arranged on the top.

[0028] In another technical solution, a plug spacer block 7 is further arranged between the jack 8 and the limit block 5, which is composed of multiple base blocks and is used to control the thickness of the plug spacer block 7, thereby adjusting the distance between the jack 8 and the limit block 5.

[0029] Since the limit block 5 is fixed on the sliding track 3, if the position of the jack 8 needs to be adjusted, after the adjustment is completed, the space between the jack 8 and the limit block 5 is filled with plug spacer blocks 7 of different thicknesses. The thickness of the plug spacer block 7 is adjusted by setting different numbers of base blocks.

[0030] An installation and construction method for a simple beam body lateral sliding device of the present utility model includes the following steps:

[0031] Step 1: Material preparation. Prepare the materials of the support system 2, sliding tracks 3, connecting beam 4, limit block 5, limit box 6, plug spacer block 7, jack 8, and sliding tracks 3 used for the device. At the same time, bolt holes are reserved in the beam body 1 in advance to provide conditions for inserting bolts 9 subsequently.

[0032] Step 2: Erect the support system 2, and determine the length and position of the sliding tracks 3 according to the actual situation on site;

[0033] Step 3: Fix the sliding tracks 3 and the support system 2 to form an integral body;

[0034] Step 4: Fix the jack limit block 5 and the sliding track 3 firmly;

[0035] Step 5: Place the jack 8 at the jack limit block 5;

[0036] Step 6: Place the jack limit box 6 and adjust the length of the jack 8 to make them closely fit;

[0037] Step 7: Fix the jack limit box 6 and the connecting beam 4 firmly to form an integral body;

[0038] Step 8: Place the beam body 1 on the sliding tracks 3 and carry out limiting;

[0039] Step 9: Insert the bolts 9 into the reserved holes of the beam body 1 and the holes of the connecting beam 4 and fix them firmly;

[0040] Step Ten: Remove the limit on the beam body 1, pressurize the jack 8, push the jack limit box 6 through the jack 8, drive the connecting beam 4 to move forward, and thus realize the lateral sliding of the beam body 1 on the sliding track 3. During the forward movement of the jack 8, the gap between the jack 8 and the jack limit block 5 is filled with the plugging cushion block 7 in a timely manner.

[0041] Step Ten: After the beam body 1 reaches the required position, carry out the limiting;

[0042] Step Eleven: Release the pressure of the jack 8, remove the connection between the jack limit box 6 and the connecting beam 4, loosen the bolt 9, and remove the connection between the beam body 1 and the connecting beam 4. After the constraints of each component of the device are removed, carry out the recycling.
