[0035] The utility model is described in detail below.

[0036] like Figure 1-Figure 5 As shown:

[0037] A telescopic sleeper stop device comprises a base plate 1, and a stop assembly installed on the base plate 1 and extending vertically;

[0038] The stop assembly includes a telescopic assembly 2 installed on a base plate 1 , an upper crossbeam 3 installed on the telescopic assembly 2 , and a position limiting assembly 4 for connecting the telescopic assembly 2 and the upper crossbeam 3 .

[0039] The telescopic component 2 is used to adjust and control the distance between the upper crossbeam 3 and the bottom plate 1. When in use, the distance between the upper crossbeam 3 and the bottom plate 1 can be adjusted according to the height of the stacked sleepers, thereby stopping the stacked sleepers and preventing the sleepers from falling during transportation; the limit component 4 effectively limits the maximum distance between the upper crossbeam 3 and the bottom plate 1 to prevent the upper crossbeam 3 and the telescopic component 2 from falling off.

[0040] In some possible implementations, in order to effectively enhance the connection stability between the telescopic assembly 2 and the base plate 1;

[0041] It also includes a diagonal bracing assembly 5 installed on the base plate 1 and connected to the telescopic assembly 2 .

[0042] In some possible implementations, in order to effectively adjust and control the distance between the upper cross beam 3 and the bottom plate 1, so as to adapt to the stop of sleepers with different stacking heights;

[0043] The telescopic assembly 2 includes a plurality of groups of stopper beams 21 arranged in parallel and respectively mounted on the bottom plate 1, telescopic beams 22 arranged one by one corresponding to the stopper beams 21 and slidingly matched along the vertical direction, and a connecting assembly 23 for connecting two adjacent groups of stopper beams 21;

[0044] A plurality of through holes are vertically arranged on the stop vertical beam 21 and the telescopic beam 22, respectively, and the stop vertical beam 21 is connected to the corresponding telescopic beam 22 by bolts;

[0045] The stop vertical beam 21 is a rectangular hollow steel tube, and the telescopic beam 22 is a rectangular square steel and is sleeved inside the stop vertical beam 21;

[0046] The stop vertical beam 21 is vertically arranged and installed on the bottom plate 1 by welding. It is a rectangular hollow steel tube. The telescopic beam 22 is a rectangular square steel sleeved in the stop vertical beam 21. The end thereof away from the bottom plate 1 is welded to the bottom of the upper cross beam 3.

[0047] The stop vertical beams 21 and the telescopic beams 22 are arranged one by one, and the top ends of all the telescopic beams 22 are connected to the upper cross beam 3;

[0048] By controlling one end of the telescopic beam 22 in the vertical direction, the distance between the upper cross beam 3 and the bottom plate 1 is adjusted. When the distance is adjusted to the right position, each set of stopper vertical beams 21 is fixed to the corresponding telescopic beam 22 by using bolts and through holes.

[0049] In some possible implementations, in order to make the entire telescopic assembly 2 have good stability;

[0050] The connecting assembly 23 includes a connecting crossbeam 231 disposed between two adjacent groups of stop vertical beams 21 , and a supporting rib plate 232 installed on the connecting crossbeam 231 and used to connect the connecting crossbeam 231 and the stop vertical beam 21 .

[0051] The connecting cross beam 231 connects two adjacent groups of stop vertical beams 21 , and the connection between the connecting cross beam 231 and the stop vertical beam 21 is strengthened by the supporting rib plate 232 .

[0052] In some possible implementations, in order to prevent the telescopic beam 22 from being separated from the stop vertical beam 21;

[0053] The limiting assembly 4 is located above each group of connecting cross beams 231 and two groups of connecting beams 42 are respectively connected to two adjacent groups of stop vertical beams 21, and a guide rod 41 is used to connect the beams 42 and the upper cross beam 3 and is arranged vertically;

[0054] A through hole for the guide rod 41 to pass through is respectively provided on the upper cross beam 3 and the connecting beam 42; the guide rod 41 is similar to a bolt, and an end cap is provided at one end close to the upper cross beam 3, and a thread is provided at the other end of the guide rod 41;

[0056] The threaded end of the guide rod 41 will pass through the upper cross beam 3, the connecting beam 42 and the nut to be connected, and the end cap at the other end of the guide rod 41 will limit the guide rod 41; when in use, the upper cross beam 3 is controlled to move upward, thereby driving the telescopic beam 22 and the guide rod 41 to move upward;

[0057] When the telescopic beam 22 is adjusted to the required height, reinstall the bolts, nuts and washers to connect the telescopic beam 22 to the stop vertical beam 21, so that the telescopic beam 22 is fixed at the required height to prevent the sleeper from falling;

[0058] When the telescopic beam 22 moves to the limit, the nut at the lower end of the guide rod 41 also moves to the connecting beam 42 and is restricted, so that the guide rod 41 and the upper cross beam 3 cannot move upward further, and the telescopic beam 22 will not separate from the stop vertical beam 21;

[0059] After unloading the sleepers, remove the bolts used to fix the stop vertical beam 21 and the telescopic amount, wait for the telescopic beam 22 to fall into the stop vertical beam 21 with its own weight, and reinstall the bolts, nuts and washers.

[0061] The upper cross beam 3 includes a channel steel that is horizontally arranged and connected to the telescopic beam 22 , a sealing plate 31 arranged at both ends of the channel steel, and a lifting lug 32 arranged on the sealing plate 31 .

[0062] The lifting lug 32 is provided to facilitate the lifting of the upper beam 3 by a lifting device;

[0063] In some possible implementations, in order to effectively strengthen the connection between the stop vertical beam 21 and the bottom plate 1, so that the device is more stable and firm;

One end of the diagonal brace 51 is connected to the bottom plate 1, and the other end is connected to the stop vertical beam 21, forming a right-angled triangle structure; the reinforcing beam 52 is added between the two diagonal braces 51 to make the structure of the diagonal brace assembly 5 more stable.

[0065] Furthermore, the diagonal brace 51, the connecting beam 42, and the connecting cross beam 231 are all channel steels.

[0066] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
