DETAILED DESCRIPTION

[0024] like Figure 1 to Figure 5As shown, the present invention is a fixing device for a cushion beam 26 of a walking-type pushing device, which is arranged above the pushing component of the walking-type pushing device, and includes a hollow and rectangular installation box 1, an upper end plate 3 and a lower end plate 2 are fixedly provided at both ends of the installation box 1, a threaded column 4 is provided between the upper end plate 3 and the lower end plate 2, and both ends of the threaded column 4 are rotatably connected to the middle of the upper end plate 3 and the lower end plate 2, respectively, a worm wheel 7 is provided on one end of the threaded column 4 close to the lower end plate 2, the middle part of the worm wheel 7 is fixed on the threaded column 4, a worm 8 is provided on the outer side of the worm wheel 7, the worm 8 and the worm wheel 7 are meshed, and the worm 8 A rotating rod 9 is provided on one end of the worm gear 8, one end of the rotating rod 9 is fixed on the worm gear 8, the other end of the rotating rod 9 passes through the mounting box 1 and is rotatably arranged on the mounting box 1, a first threaded sleeve 10 is provided above the worm gear 7, the first threaded sleeve 10 is threadedly connected to the threaded column 4, four groups of circumferentially evenly distributed connecting rod assemblies are provided on the outer surface of the first threaded sleeve 10, one end of the connecting rod assembly is connected to the first threaded sleeve 10, and a stop rod 21 is provided on the other end of the connecting rod assembly, the other end of the connecting rod assembly is connected to the stop rod 21, the upper end portion of the stop rod 21 passes through the upper end plate 3, and is slidably arranged with the upper end plate 3.

[0025] The working principle of the above technical solution is:

[0026] When performing the jacking operation, the pad beam 26 is placed on the upper end plate 3, and then the operator rotates the rotating rod 9, which drives the worm 8 to rotate, and the worm 8 drives the worm wheel 7 to rotate, and the worm wheel 7 drives the threaded column 4 to rotate. Since the rotation of the first threaded sleeve 10 is limited by the connecting rod assembly and the stop rod 21, the first threaded sleeve 10 will move on the threaded column 4, and then the movement of the first threaded sleeve 10 will drive the connecting rod assembly and the stop rod 21 to move upward, and the upward moving stop rod 21 will contact the outer surfaces of multiple pad beams 26, thereby limiting the movement of the pad beams 26. By arranging the stop rods 21 around the pad beams 26, the movement of several overlapping pad beams 26 is limited, thereby ensuring the stability of the pad beams 26 during the jacking operation, and improving the safety during the jacking operation.

[0027] In one practicable manner, the connecting rod assembly includes a first rotating ring 11, a second rotating ring 12, a first connecting rod 13 and a second connecting rod 14. The first rotating ring 11 is sleeved on the outer surface of the first threaded sleeve 10, and the second rotating ring 12 is sleeved on the outer surface of the lower end of the blocking rod 21. The connection method here is that it can rotate but cannot move up and down. One end of the first connecting rod 13 is fixed to the first rotating ring 11, and a rotating shaft 15 is provided on the other end of the first connecting rod 13. The rotating shaft 15 rotatably connects one end of the second connecting rod 14 to the other end of the first connecting rod 13. The other end of the second connecting rod 14 is fixed to the second rotating ring 12, and a rotating shaft 15 is provided on the rotating shaft A U-shaped mounting frame 16, both ends of which are rotatably connected to both ends of the rotating shaft 15, a screw rod 20 is provided on the closed end of the U-shaped mounting frame 16, the screw rod 20 is rotatably connected to the closed end of the U-shaped mounting frame 16, and the displacement of the screw rod 20 on the U-shaped mounting frame 16 can be limited by means of a retaining ring 17, the screw rod 20 passes through the mounting box 1, and a vertical groove 23 is provided at the contact portion between the mounting box 1 and the screw rod 20, a nut 19 is provided in the vertical groove 23, the nut 19 is slidably set in the vertical groove 23, the screw rod 20 is threadedly connected to the nut 19, a transverse groove 22 is provided on the upper end plate 3, and the retaining rod 21 is located in the transverse groove 22.

[0028] With this arrangement, the angle between the first connecting rod 13 and the second connecting rod 14 can be adjusted by rotating the screw rod 20, thereby changing the position of the blocking rod 21 in the transverse groove 22, and the four blocking rods 21 can be adjusted individually to match the cushion beams 26 with different length-width ratios. The specific implementation method is: when the position of the blocking rod 21 needs to be adjusted, it is only necessary to rotate the screw rod 20. Since the position of the nut 19 is limited, the screw rod 20 will be extended and retracted. The extended screw rod 20 will change the angle between the first connecting rod 13 and the second connecting rod 14. Since the position of the blocking rod 21 is limited, it can only move horizontally and vertically in the transverse groove 22. Therefore, when the angle between the first connecting rod 13 and the second connecting rod 14 changes, the blocking rod 21 cannot rotate, so it can only move in the transverse groove 22, thereby changing the distance between the blocking rod 21 and the center of the upper end plate 3, thereby matching and adapting to the pad beams 26 of different sizes; at the same time, in this setting mode, when the pad beam 26 is placed on the upper end plate 3, the blocking rod 21 can be moved to the middle of the upper end plate 3 by rotating the screw rod 20 outward, thereby clamping the pad beam 26. Of course, when the pad beam 26 needs to be removed, it is only necessary to move the blocking rod 21 outward and lower it.

[0029] In one feasible manner, limiting ribs 18 are provided on both sides of the vertical groove 23, one side of the limiting rib 18 is fixed on the inner wall of the vertical groove 23, and sliding grooves are symmetrically provided on the nut 19, which are slidably connected to the limiting rib 18. This setting method limits the rotation of the nut 19 and can also move with the upward movement of the blocking rod 21. The structure is simple and ingenious.

[0030] In one feasible manner, at least one baffle rod 21 is provided with an external thread 25, and a second threaded sleeve 24 is threadedly connected to the external thread 25. The outer surface of the second threaded sleeve 24 is connected to the inner surface of the second rotating ring 12. When the truss and other components are located above the pushing component, the cushion beam 26 cannot be inserted from above the upper end plate 3. At this time, the second threaded sleeve 24 can be clamped by a tool such as a wrench, and then the baffle rod 21 with the external thread 25 is rotated to make the baffle rod 21 move up and down in the second threaded sleeve 24, thereby opening a gap to facilitate the insertion of the cushion beam 26 from the gap. After insertion, the baffle rod 21 can be rotated to reset. Of course, the length of the second threaded sleeve 24 is preferably greater than the length of the second rotating ring 12, so that the operator can clamp the second threaded sleeve 24. The clamping tool can enter by opening an operating hole in the installation box 1, and no further details will be given here.

[0031] In one feasible method, both ends of the threaded column 4 are provided with rotating bearings, which can be divided into an upper rotating bearing 5 and a lower rotating bearing 6. The outer rings of the rotating bearings are respectively fixed on the upper end plate 3 and the lower end plate 2, and the inner rings of the rotating bearings are fixed on the ends of the threaded column 4.

[0032] In one practicable manner, an annular groove is provided on the inner ring of the first rotating ring 11 and the second rotating ring 12, and an annular ridge is provided on the outer surface of the first threaded sleeve 10 and the outer surface of the blocking rod 21, and the annular groove is respectively rotatably sleeved on the annular ridge. This method can realize rotation, but it cannot be unique up and down. Of course, a simple method is to use the first rotating ring 11 and the second rotating ring 12 as bearings, and then the inner and outer rings are respectively connected to corresponding components.

[0033] In one practicable manner, a hexagonal column is fixedly provided on the upper end of the blocking rod 21 provided with the external thread 25 to facilitate the rotation of the blocking rod 21 .

[0034] In one practicable manner, a plurality of reinforcing support ribs are evenly distributed on the circumference of the outer surface of the installation box 1 to improve the bearing capacity of the installation box 1 .

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
