[0039] In this embodiment, the retractable guardrail includes:

[0040] The base assembly 100 includes a base plate 101, a base quick-insertion plate 102, a plurality of base support ribs 103, and a base guide plate 104 connected between the base support ribs 103. The base support ribs 103 are disposed on the top of the base plate 101, and the base quick-insertion plate 102 is disposed on the bottom of the base plate 101. The base quick-insertion plate 102 can be connected to the quick slot 02 of the rear filling device 01.

[0041] The telescopic mechanism 200 includes a plurality of telescopic support ribs 201 and a telescopic limiting plate 202 connected between each telescopic support rib 201. Each telescopic support rib 201 has a sliding groove 201-1 in the middle. The telescopic support rib 201 is slidably connected to the base support rib 103, and the base guide plate 104 is located in the sliding groove 201-1.

[0042] The locking mechanism 300 is installed on the telescopic mechanism 200 or the base assembly 100. The locking mechanism 300 can lock the telescopic limit plate 202 when it moves to a position corresponding to the base guide plate 104.

[0043] Specifically, the base assembly 100 can be considered as a whole, with all components of the base assembly 100 fixedly connected to ensure its strength. Similarly, the telescopic mechanism 200 can also be considered as a whole, with all components of the telescopic mechanism 200 fixedly connected to ensure its strength. In the base assembly 100, the base plate 101 provides support and can be placed horizontally. A base support rib 103 is welded to the upper part of the base plate 101, and a base quick-insertion plate 102 is welded to the lower part. Both the base support rib 103 and the base quick-insertion plate 102 extend vertically. When the base quick-insertion plate 102 is inserted into the quick slot 02 of the rear filling device 01, the base plate 101 can also limit the movement of the upper surface of the quick slot 02. (Base guide) Plate 104 also extends horizontally. The function of base guide plate 104 is to connect the two base support ribs 103 and to effectively limit the movement of telescopic support rib 201 in telescopic mechanism 200. The telescopic support rib 201 in telescopic mechanism 200 extends vertically, and telescopic limiting plate 202 extends horizontally. The function of telescopic limiting plate 202 is to connect the two telescopic support ribs 201 and to lock the position of telescopic mechanism 200 by locking telescopic limiting plate 202, which facilitates height adjustment of telescopic mechanism 200. For ease of use, locking mechanism 300 can be set on the upper part of base support rib 103. Locking mechanism 300 can be a structure such as elastic snap ring or rotary locking tongue 302.

[0044] The telescopic guardrail provided by this utility model connects the quick-release plate 102 of the base assembly 100 with the quick-slot 02 of the rear filling device 01, facilitating the quick installation and positioning of the base assembly 100. The sliding engagement between the telescopic mechanism 200 and the base assembly 100 allows for easy height adjustment of the telescopic mechanism 200 to match the height of the front hydraulic support, preventing scratches and damage to the rear hydraulic lines. Simultaneously, the locking mechanism 300 enables quick locking of the telescopic mechanism 200's position. This telescopic guardrail effectively ensures the safety of personnel working at the rear, is easy to operate, and has good applicability.

[0045] In some embodiments, both the telescopic limiting plate 202 and the base guide plate 104 are provided with limiting holes 203. The locking mechanism 300 can pass through the limiting holes 203 of the telescopic limiting plate 202 and the base guide plate 104 to lock the telescopic limiting plate 202. Specifically, the limiting holes 203 on the telescopic limiting plate 202 and the base guide plate 104 should be positioned correspondingly to ensure that the locking mechanism 300 can pass through the limiting holes 203 of the telescopic limiting plate 202 and the base guide plate 104 at the same time. Since the position of the base guide plate 104 remains unchanged, after locking the telescopic limiting plate 202 and the base guide plate 104, the position of the telescopic limiting plate 202 can be locked, which means the height of the telescopic mechanism 200 can be locked.

[0046] In some embodiments, the locking mechanism 300 includes a locking shaft 301 and a locking tongue 302. The locking shaft 301 is located on the base support rib 103 and is flush with the base guide plate 104. The locking tongue 302 is hinged to the locking shaft 301 and can pass through the telescopic limiting plate 202 and the limiting hole 203 of the base guide plate 104. Specifically, the locking shaft 301 can be fixed on the base support rib 103, or it can be fixed on the telescopic support rib 201. By rotating the locking tongue 302, it can cooperate with the limiting hole 203 to achieve both unlocking and locking states. The locking tongue 302 can be U-shaped. After the locking tongue 302 passes through the telescopic limiting plate 202 and the base guide plate 104, the outer end of the locking tongue 302 will not extend too far to avoid accidental contact that could cause locking failure.

[0047] In some embodiments, there are multiple base guide plates 104, and each base guide plate 104 is arranged at intervals along the extension direction of the base support rib 103, and the upper and lower parts of the base support rib 103 are provided with base guide plates 104. Specifically, only one locking mechanism 300 may be provided, or the number of locking mechanisms 300 may be the same as the number of base guide plates 104, and a locking mechanism 300 may be provided at the position corresponding to each base guide plate 104. Multiple telescopic limit plates 202 may also be provided. In the locked state, multiple locking mechanisms 300 can be used to lock simultaneously, thereby improving the positional stability of the telescopic mechanism 200.

[0048] In some embodiments, the base assembly 100 further includes a base protective tube 105 and an auxiliary support rib 106 disposed outside the base support rib 103. The auxiliary support rib 106 extends upward at an angle away from the base support rib 103. One end of the base protective tube 105 is fixed to the base support rib 103, and the other end is suspended. The middle part of the base protective tube 105 is fixed to the auxiliary support rib 106. Specifically, each base support rib 103 has a base protective tube 105 and an auxiliary support rib 106 on its outer side, which provide protection for both sides of the base assembly 100. The suspended end of the base protective tube 105 can extend downward at an angle to improve the protective effect and increase its own strength.

[0049] In some embodiments, the telescopic mechanism 200 further includes a telescopic protective tube 204, which spans the top of each telescopic support rib 201, with both ends of the telescopic protective tube 204 extending and suspended outside the telescopic support rib 201. The telescopic protective tube 204 expands the protection area and connects to the top of the telescopic support rib 201. The length of the telescopic protective tube 204 can be set according to the space size of the application scenario. Furthermore, the telescopic protective tube 204 is also provided with an accessory plate 205, on which communication equipment and other components can be installed for convenient use.

[0050] In some embodiments, the top of the telescopic support rib 201 is bent and extended to form a bent end 201-2, with the bending direction of the bent end 201-2 facing the front side of the telescopic support rib 201. A locking groove 201-3 is provided on the upper rear side of the bent end 201-2, and the locking groove 201-3 slopes upwards from the front side to the rear side of the telescopic support rib 201. The telescopic protective tube 204 is disposed within the locking groove 201-3. Specifically, the telescopic protective tube 204 can be welded and fixed within the locking groove 201-3 to ensure the positional stability of the telescopic protective tube 204. Similarly, the suspended end of the telescopic protective tube 204 also extends downwards at an angle to improve the protective effect and increase its own strength.

[0051] In some embodiments, the telescopic limiting plate 202 has at least one set, and each set of telescopic limiting plates 202 includes a first telescopic limiting plate 202-1 and a second telescopic limiting plate 202-2. The first telescopic limiting plate 202-1 and the second telescopic limiting plate 202-2 are respectively connected to the telescopic support rib 201 and located on both sides of the slide groove 201-1. That is, the telescopic support rib 201 is provided with two rows of telescopic limiting plates 202, and the two rows of telescopic limiting plates 202 are respectively located on both sides of the slide groove 201-1, which can better fix the telescopic support rib 201. When the telescopic mechanism 200 slides up and down, the two rows of telescopic limiting plates 202 pass through the front and rear sides of the base guide plate 104, and the guiding effect is good.

[0052] In some embodiments, the telescopic limiting plate 202 is provided in multiple sets, with each set of telescopic limiting plates 202 arranged at intervals along the extension direction of the telescopic support rib 201. That is, one or more sets of telescopic limiting plates 202 can be provided. When there is only one set of telescopic limiting plates 202, it can be set at the bottom of the telescopic support rib 201. When the telescopic mechanism 200 is raised to the high position, the locking mechanism 300 locks the telescopic limiting plate 202. After the telescopic limiting plate 202 is unlocked, the telescopic mechanism 200 can be placed on the base assembly 100 under the action of gravity, at which time the telescopic mechanism 200 is in the low position. Of course, when there are multiple sets of telescopic limiting plates 202, the height of the telescopic mechanism 200 can be adjusted to multiple positions as needed.

[0053] In one specific embodiment, when the telescopic guardrail is needed, the upper telescopic mechanism 200 slide is first inserted into the base guide plate 104 of the base assembly 100. The base guide plate 104 can restrict the degree of freedom of the telescopic mechanism 200 to prevent it from tipping over. During normal operation, the telescopic limit plate 202 of the telescopic mechanism 200 and the base guide plate 104 of the base assembly 100 are adjusted to the same horizontal line and locked by the rotation locking mechanism. When the filling device needs to be moved forward after the operation is completed, the upper telescopic mechanism 200 needs to be retracted and lowered to avoid pulling on the hose and cable of the front hydraulic support.

[0054] In addition to the aforementioned telescopic guardrail, this utility model also provides a paste filling hydraulic support that includes the aforementioned telescopic guardrail. For the structure of other parts of the paste filling hydraulic support, please refer to relevant technologies, which will not be repeated here.

[0055] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0056] The telescopic guardrail provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
