Embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by drawings and Examples,
The utility model is further elaborated.However, it should be understood that specific embodiment described herein is only solving
The utility model is released, is not limited to the scope of the utility model.
As shown in Figure 1 and Figure 2, a kind of hydraulic prop falling-proof bracket, including snap ring 3 for fixed hydraulic pillar,
For the connecting plate 1 for installing snap ring 3, the connecting plate 28 being connected with connecting plate 1 and bottom plate for supporting connecting plate 28
10；
The snap ring 3 is in semi-annular shape, and the both ends of snap ring 3 are provided with tight lock part 4, some lockings are provided with the tight lock part 4
Hole 5；
The snap ring 3 is fixed on connecting plate 1, is provided with some connecting holes 1 in row on connecting plate 1, is set in connecting hole 1
There is screw thread, the connecting plate 28 is connected by bolt 6 with connecting plate 1, and the bottom of connecting plate 28 is fixed with the bottom plate 10,
The bottom plate 10 is fixed on the ground by voussoir 9.
As the improvement of embodiment, the longitudinal measure of connecting plate 1 is at the outer side center of snap ring 3.When snap ring 3 is set with
At hydraulic prop both sides, snap ring 3 is supported by connecting plate 1.
As the improvement of embodiment, some reinforcing plates 7, the reinforcing plate 7 are welded between the connecting plate 28 and bottom plate 10
Using steel plate, effectively play to the reinforcing of connecting plate 28 and the connection of bottom plate 10, firm effect, improve integrally-built stabilization
Property.
As the improvement of embodiment, for the bottom plate 10 in sector, contact area is big, and it is more stable to be fixed on ground；The company
