[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 5 As shown:

[0020] Embodiment 1: The utility model provides a hydraulic lifting device for a large-angle mining working face, comprising: a supporting mechanism 1, comprising a supporting seat assembly 11, a supporting crossbar assembly 12 rotatably embedded on the supporting seat assembly 11, and a positioning assembly 13 installed on the supporting seat assembly 11, wherein the positioning assembly 13 can position the supporting crossbar assembly 12; a lifting mechanism 2, comprising a rotating arm member 21 installed on the supporting seat assembly 11, a cross bracing arm member 22 rotatably embedded on the rotating arm member 21, and a hydraulic cylinder member 23 for driving the cross bracing arm member 22 to rotate around the rotating arm member 21;

[0021] Among them, when the supporting cross bar assembly 12 is needed, moving the positioning assembly 13 downward can release the positioning of the supporting cross bar assembly 12. At this time, the staff can rotate the supporting cross bar assembly 12 around the supporting seat assembly 11, so that it is horizontally placed on the supporting seat assembly 11. At this time, the staff can place heavy objects on the supporting cross bar assembly 12 and the supporting seat assembly 11; controlling the rotating arm member 21 can drive the cross bracing arm member 22 and the hydraulic cylinder member 23 to rotate, and the hydraulic cylinder member 23 can drive the cross bracing arm member 22 to rotate around the rotating arm member 21, thereby facilitating the lifting of heavy objects.

[0022] Specifically, the support seat assembly 11 includes a support seat body 111, and a group of transverse fork arms 112 are fixedly connected to one side of the support seat body 111. The transverse fork arms 112 are also provided with a torsion spring accommodating groove 113. A limiting shaft rod 114 is fixedly connected to the transverse fork arm 112 and located in the torsion spring accommodating groove 113. A torsion spring 115 is also sleeved on the outer side of the limiting shaft rod 114.

[0023] Specifically, the support crossbar assembly 12 includes a support crossbar body 121 , and a handle 122 is fixedly connected to the outer side of the support crossbar body 121 .

[0024] Specifically, the support cross bar body 121 is limitedly rotated and embedded in the limit shaft 114 , one end of the torsion spring 115 is embedded in the support cross bar body 121 , and the other end of the torsion spring 115 is embedded in the support cross bar body 121 .

[0025] As can be seen from the above, the torsion spring 115 can drive the support cross bar body 121 to rest on the cross fork arm 112, so as to facilitate the use of the staff. The handle 122 can facilitate the staff to rotate the support cross bar body 121, and the limiting shaft 114 can limit the support cross bar body 121.

[0026] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a guide limit rod 116 is fixedly connected to the transverse fork arm 112; the positioning assembly 13 includes a T-shaped positioning block 131, and a spring 132 is fixedly connected to the lower side of the T-shaped positioning block 131; wherein, the guide limit rod 116 can play a guiding role for the T-shaped positioning block 131 and the spring 132.

[0027] Specifically, the T-shaped positioning block 131 and the spring 132 are both limited and slidably embedded in the guide limiting rod 116, and the spring 132 drives the T-shaped positioning block 131 to move upward and embed into the supporting cross bar body 121; moving the T-shaped positioning block 131 downward can release the positioning of the supporting cross bar body 121, and at the same time, the downward movement of the T-shaped positioning block 131 will cause the spring 132 to be compressed, so that after releasing the T-shaped positioning block 131, the spring 132 resets and causes the T-shaped positioning block 131 to move upward again, which can facilitate the positioning of the supporting cross bar body 121 again.

[0028] As can be seen from the above, the handle 122 is used to drive the support cross bar body 121 to rotate around the limiting shaft 114. When the support cross bar body 121 is stored on the cross fork arm 112, the support cross bar body 121 can be positioned by the T-shaped positioning block 131. Pushing the T-shaped positioning block 131 downward can compress the spring 132 and release the support cross bar body 121. At this time, the staff can conveniently use the support cross bar body 121.
