Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0046] As Figures 1 to 6 shown, this embodiment proposes

[0047] A rapid replacement support device for a hydraulic support jack, comprising

[0048] Moving member 1;

[0049] Rotating member 2, arranged on the moving member 1, and the moving member 1 is used to drive the rotating member 2 to move;

[0050] Lifting member 3, arranged on the rotating member 2, the lifting direction of the lifting member 3 is parallel to the rotation axis of the rotating member 2, and the rotating member 2 is used to drive the lifting member 3 to rotate;

[0051] Bracket 4, arranged on the lifting member 3, the bracket 4 is used to support the jack, and the lifting member 3 is used to drive the bracket 4 to lift;

[0052] Support mechanism 5, having several, arranged on the moving member 1, and the support mechanism 5 includes

[0053] Bracket 6, arranged on the moving member 1;

[0054] Support frame 7, arranged on the bracket 6;

[0055] The sliding rod 8 is slidably arranged on the support frame 7, and the sliding rod 8 has a plurality of grooves 9;

[0056] The driving disk 10 is rotatably arranged on the bracket 6. The driving disk 10 has a spiral boss 11. The spiral boss 11 abuts against the groove 9. After the driving disk 10 rotates, it drives the sliding rod 8 to slide up and down. After a plurality of sliding rods 8 move downward, they support the moving member 1.

[0057] In this embodiment, in order to solve the problems of insufficient support of mobile devices and inconvenient adjustment of the installation angle of the jack in the related art, a support mechanism 5 and a rotating member 2 are arranged on the moving member 11. By rotating the driving disk 10 of the support mechanism 5, the sliding rod 8 is driven to slide downward along the support frame 7. A plurality of support mechanisms 5 can support the moving member 1, so that when installing the jack, the moving member 1 does not contact the ground, reducing the pressure on the moving member 1 during the installation of the jack. If there is a problem with the support mechanism 5, it is also convenient for maintenance and replacement. The rotating member 2 facilitates adjusting the angle of the jack according to the installation position during the installation of the jack, without the need to frequently move the moving member 1 in a narrow space to adjust the position of the jack. During use, it only needs to move the jack to the lower part of the installation position through the moving member 1.

[0058] Specifically, when using the quick replacement support device for the jack of the hydraulic support 6 to replace the jack, first, the operator places the jack on the bracket 4, and then operates the moving member 1 to move the jack to the lower part of the installation position. Then rotate the driving disk 10 of the support mechanism 5. The spiral boss 11 of the driving disk 10 rotates together, and abuts against the groove 9 during the rotation process, driving the sliding rod 8 to move downward along the support frame 7. After the sliding rod 8 contacts the ground, it continues to move downward and separates the moving member 1 from the ground. Operate the lifting member 3 to rise. The lifting member 3 drives the bracket 4 to rise together to make the jack close to the installation position to be replaced. At this time, the rotating member 2 can be operated according to the angle of the installation position. The rotating member 2 drives the jack to rotate so that the angle of the jack is consistent with the installation position. Finally, adjust the height of a plurality of lifting members 3 according to the height difference of the installation holes at the installation position to finely adjust the position of the jack, solving the problems of insufficient support of mobile devices and inconvenient adjustment of the installation angle of the jack in the related art.

[0059] Furthermore, it further includes

[0060] A bottom plate 12 is arranged at one end of the sliding rod 8. After the sliding rod 8 moves downward, the bottom plate 12 abuts against the ground.

[0061] In this embodiment, a bottom plate 12 is also arranged at one end of the sliding rod 8. The bottom plate 12 can increase the contact area between the support mechanism 5 and the ground when the support mechanism 5 supports the moving member 1, improving the stability of the support.

[0062] Furthermore, the rotating member 2 includes

[0063] The frame 13 is arranged on the moving member 1, and the frame 13 has a tapered through hole 14;

[0064] The rotating shaft 15 is rotatably arranged on the frame 13, and the rotating shaft 15 is located in the tapered through hole 14;

[0065] The frustum 16 is slidably arranged on the rotating shaft 15, the frustum 16 abuts against the inner wall of the tapered through hole 14, and several notches 17 are provided at the small end of the frustum 16;

[0066] The elastic member 18 is respectively arranged at both ends on the frame 13 and the frustum 16;

[0067] The handle 19 is sleeved on the rotating shaft 15, several first bosses 20 are provided on the handle 19, and after the first bosses 20 abut against the notches 17, the handle 19 drives the rotating shaft 15 to rotate;

[0068] The top plate 21 is arranged on the rotating shaft 15, and the lifting member 3 is arranged on the top plate 21.

[0069] In this embodiment, when it is necessary to adjust the angle of the jack through the rotating member 2, the handle 19 is rotated, the first boss 20 abuts against the notch 17, the axial force generated therein pushes the frustum 16 upward, the elastic member 18 is compressed, the friction between the frustum 16 and the tapered through hole 14 is reduced, the radial force generated pushes the frustum 16 to rotate, the rotating shaft 15 starts to rotate driven by the frustum 16, and the top plate 21 rotates together therewith, so that the angle of the jack can be adjusted. When it is not necessary to adjust the angle of the jack, the elastic member 18 presses the frustum 16 against the tapered through hole 14 of the frame 13, and the rotating shaft 15 cannot be rotated by the force on the top plate 21, and the rotating member 2 realizes self-locking, avoiding danger during the installation of the jack.

[0070] Furthermore, the support frame 7 has a first through groove 22, one end of the sliding rod 8 has a limiting rod 23, and the limiting rod 23 is located in the first through groove 22.

[0071] In this embodiment, when the sliding rod 8 slides along the support frame 7, the limiting rod 23 also slides in the first through groove 22, and the displacement of the sliding rod 8 is displayed through the length of the first through groove 22, avoiding the sliding rod 8 from coming out of the support rod 7, so as to prevent the moving member 1 from tipping over during the support process of the support mechanism 5.

[0072] Furthermore, the bracket 4 includes

[0073] The arc-shaped frame 24 is arranged on the lifting member 3;

[0074] The support frame 25 is arranged on the lifting member 3;

[0077] The connecting rod 28 has two ends rotatably disposed on the first telescopic member 26 and the clamping member 27 respectively. The first telescopic member 26 is used to drive the connecting rod 28 to rotate. After the connecting rod 28 rotates, it drives the clamping members 27 to move closer to or away from each other.

[0078] In this embodiment, when placing the jack on the bracket 4, the jack is first placed on the arc plate of the bracket 4, and then the first telescopic member 26 is controlled to extend, and the connecting rod 28 rotates accordingly and drives the clamping member 27 to slide along the support frame 25. After the clamping members 27 slide, they approach each other and clamp the jack to prevent the jack from falling from the bracket 4 during the lifting process of the lifting member 3.

[0079] Furthermore, the clamping member 27 has a plurality of limiting holes 29, and the bracket 4 also includes

[0080] The limiting pin 30 is disposed in the limiting hole 29 , and is used to adjust the sliding distance of the clamping member 27 .
