[0029] Example 1

[0030] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a wind power booster station oil replenishing device, including a supporting assembly 200, a lifting assembly 300, and a moving assembly 400; wherein the supporting assembly 200 is used to support the oil replenishing tank 100; the lifting assembly 300 can clamp the edge of the top cover of the oil replenishing tank 100, and then lift the oil replenishing tank 100; the moving assembly 400 is used to control the overall movement, retreat, and reversing of the device.

[0031] Furthermore, the support assembly 200 includes a lateral stabilizer bar 201 and a support rod 202 vertically fixed to the lateral stabilizer bar 201; the lifting assembly 300 includes a caliper mechanism 301 for clamping the oil replenishing tank 100 and a cylinder 302 for lifting the oil replenishing tank 100.

The caliper mechanism 301 is slidably arranged on the support rod 202, the piston rod end of the cylinder 302 is fixed to the caliper mechanism 301, and the piston rod of the cylinder 302 is arranged parallel to the axial direction of the support rod 202.

[0032] When in use, the support rod 202 is brought close to the oil replenishing tank 100, and the caliper mechanism 301 is located at the top cover attachment of the oil replenishing tank 100. The caliper mechanism 301 is raised and lowered by the cylinder 302 so that the top cover edge of the oil replenishing tank 100 can be clamped by the caliper mechanism 301. Finally, the caliper mechanism 301 is raised again by the cylinder 302 to lift the oil replenishing tank 100, thereby transferring the oil replenishing tank 100 from the warehouse storage area to the device and supported by the support rod 202.

[0033] It is worth noting that, in some embodiments, an oil cylinder or other linear lifting mechanism may be used instead of the air cylinder 302 to lift the oil replenishing tank 100 .

[0034] As a further improvement, the caliper mechanism 301 includes a fixed seat 301a slidably set with the support rod 202, and an inner groove 301a-1 is set on the side of the fixed seat 301a away from the support rod 202, an upper clamp claw 301b is movably set inside the inner groove 301a-1, and a lower clamp claw 301c movably cooperates with the upper clamp claw 301b to clamp the edge of the top cover of the oil filling tank 100.

[0035] Specifically, the upper jaw 301b and the lower jaw 301c are arranged opposite to each other to form a clamping groove H capable of clamping the edge of the top cover of the oil replenishing tank 100. When in use, the edge of the top cover of the oil replenishing tank 100 is placed in the clamping groove H, and the upper jaw 301b-2 of the clamping jaw and the lower jaw 301c-2 of the lower jaw 301c respectively contact the upper and lower surfaces of the edge of the top cover and provide the clamping force required to fix the oil replenishing tank 100.

[0036] As a further improvement, the caliper mechanism 301 further includes a first shaft rod 301d connecting the upper jaw 301b and the fixing seat 301a, and a second shaft rod 301e connecting the lower jaw 301c and the fixing seat 301a.

[0037] Furthermore, the upper jaw 301b includes an upper jaw body 301b-1, and an upper jaw 301b-2 arranged at one end of the upper jaw body 301b-1, and the upper jaw 301b-2 is used to hook the upper edge of the top cover of the oil replenishing tank 100; the upper jaw body 301b-1 is arc-shaped, and an axial hole compatible with the first shaft rod 301d is arranged at one end of the upper jaw 301b-2 of the upper jaw 301b-2; the upper jaw 301b-2 is hook-shaped and extends out of the inner groove 301a-1, and the tip of the hook-shaped upper jaw 301b-2 extends downward.

[0038] Furthermore, the lower jaw 301c includes a lower jaw body 301c-1, and a lower jaw mouth 301c-2 arranged at one end of the lower jaw body 301c-1, and the lower jaw mouth 301c-2 can lift the lower edge of the top cover of the oil replenishing tank 100; an axial hole adapted to the second shaft rod 301e is arranged at one end of the lower jaw body 301c-1 away from the lower jaw 301c-2; the lower jaw 301c-2 extends out of the inner groove 301a-1 and has a supporting surface 301c-2a that contacts the edge of the top cover of the oil replenishing tank 100, and an inclined surface 301c-2b adjacent to the supporting surface 301c-2a and forming an acute angle.

[0039] Furthermore, a limit block 301g is disposed inside the inner groove 301a-1, and the limit block 301g can contact with the lower jaw 301c to limit the angular displacement of the lower jaw 301c deflected downward.

[0040] Furthermore, a connecting seat 301c-3 is provided on one side of the lower clamp body 301c-1 adjacent to the supporting surface 301c-2a, and a pulling shaft 301c-4 is provided on the movable end of the connecting seat 301c-3; a sliding groove 301b-3 is provided on the upper clamp body 301b-1, and the pulling shaft 301c-4 is slidably provided in the sliding groove 301b-3.

[0041] Furthermore, the caliper mechanism 301 further includes an elastic member 301f having compression and tension self-restoring properties, one end of the elastic member 301f is connected to the fixing seat 301a, and the other end of the elastic member 301f is connected to the lower jaw 301c. The elastic member 301f utilizes tension to maintain the upper jaw 301b and the lower jaw 301c in a stable state without being affected by external forces (except gravity).

[0042] When in use, the caliper mechanism 301 is arranged close to the top cover of the oil replenishing tank 100, and the caliper mechanism 301 is controlled to slide down by the cylinder 302. The edge of the top cover of the oil replenishing tank 100 contacts the inclined surface 301c-2b of the lower jaw 301c-2 of the lower jaw 301c. As the caliper mechanism 301 continues to move downward, the lower jaw 301c is pushed to rotate inside the inner groove 301a-1 with the second rotating shaft as the center, and the connecting seat 301c-3 and the pull shaft 301c-3 are connected to the lower jaw 301c. 01c-4, and the mutual cooperation between the slide groove 301b-3 (that is, the pull rod is slidably set in the slide groove 301b-3 of the upper jaw 301b, that is, the side wall of the pull rod is in conflict with the side wall of the slide groove 301b-3 of the upper jaw 301b), and then, with the rotation of the lower jaw 301c, the upper jaw 301b is pushed to rotate around the first rotating axis through the pull shaft 301c-4, so that the opening of the slot H between the upper jaw 301b and the lower jaw 301c is enlarged.

[0043] As the caliper mechanism 301 continues to move downward, the edge of the top cover of the oil replenishing tank 100 is placed in the slot H and separated from the inclined surface 301c-2b of the lower jaw 301c-2 of the lower jaw 301c. Under the action of the elastic member 301f, the lower jaw 301c is pulled to reset, and the upper jaw 301b is pulled to reset through the pulling shaft 301c-4, so that the tip of the upper jaw 301b-2 of the upper jaw 301b contacts the upper surface of the top cover.

[0044] Subsequently, the cylinder 302 is used to control the caliper mechanism 301 to move upward, so that the lower jaw 301c-2 support surface 301c-2a of the lower jaw 301c contacts the lower surface of the edge of the top cover, and the upper jaw 301b is pulled by the pull shaft 301c-4 to further clamp the top cover, thereby gradually lifting the oil replenishing tank 100. In the process of lifting the oil replenishing tank 100, under the action of the gravity of the oil replenishing tank 100, the lower jaw 301c is squeezed to rotate further downward, and then the upper jaw 301b is further pulled downward by the pull shaft 301c-4 to rotate, thereby increasing the force of clamping the oil replenishing tank 100.

[0045] Example 2

[0046] Reference Figure 2 to Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the moving assembly 400 includes a directional member 401 for controlling the advance and retreat of the device, and an adjusting member 402 for controlling the reversal of the device.

[0047] Furthermore, a diagonal support frame 203 is provided on the side of the support rod 202 away from the oil replenishment tank 100 , and the directional member 401 includes moving wheels 401a movably provided at both ends of the transverse stabilizer rod 201 , and auxiliary support wheels 401b movably provided at the movable ends of the diagonal support frame 203 .

[0048] Furthermore, the adjusting member 402 includes a steering rod 402a, a bogie 402b, and a steering wheel 402c. The support rod 202 is provided with a through hole arranged along its axial direction. The steering rod 402a passes through the through hole and is rotatably connected to the support rod 202. A handle 402d is provided at one end of the steering rod 402a. The other end of the steering rod 402a is movably connected to the bogie 402b through a cross universal joint 402e. The rotating wheel is movably provided at the movable end of the bogie 402b.

[0049] When in use, the moving wheel 401a, the auxiliary support wheel 401b, and the steering wheel 402c are all directional wheels. The moving wheel 401a and the auxiliary support wheel 401b are used for the forward and backward movement of the device, and the steering wheel 402c is used to control the moving direction of the device. When reversing is required, the steering rod 402a is driven to rotate by turning the handle 402d. Since the steering rod 402a is connected to the bogie 402b through the cross universal shaft 402e, when the steering rod 402a rotates, the bogie 402b connected thereto can be driven to rotate synchronously, that is, the bogie 402b rotates with the connection end with the cross universal shaft 402e as the center, that is, the traveling direction of the steering wheel 402c arranged at the other end of the bogie 402b changes, and the change angle is the rotation angle of the bogie 402b, so as to realize the movement reversal.

[0050] It is worth noting that the lateral stabilizer bar 201 is movably connected to the moving wheel 401a, so that the support assembly 200 can rotate around the axis of the moving wheel 401a. When the support rod 202 is perpendicular to the ground, one end of the diagonal support frame 203 with the auxiliary support wheel 401b is suspended in the air, which facilitates the caliper mechanism 301 to clamp the oil replenishment tank 100. When one end of the diagonal support frame 203 with the auxiliary support wheel 401b contacts the ground, the support rod 202 is in a tilting device, and the oil replenishment tank 100 leans against the support rod 202. At this time, the diagonal support frame 203 and the support rod 202 form a triangular structure, providing stable support for the oil replenishment tank 100.

[0051] The remaining structures are the same as those of Example 1.

[0052] Example 3

[0053] Reference Figure 2 and Figure 3 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that two symmetrical barrel holding mechanisms 204 are arranged on the support rod 202. The barrel holding mechanisms 204 can contact the side wall of the oil replenishing tank 100 and provide clamping force to clamp and fix the oil replenishing tank 100, thereby improving the stability of the oil replenishing tank 100 during transportation.

[0054] Specifically, the barrel holding mechanism 204 includes a barrel holding arm 204a, a tightening arm 204b, and a buffer belt 204c. One end of the barrel holding arm 204a is fixedly connected to the support rod 202, and the other end of the barrel holding arm 204a is movably connected to one end of the tightening arm 204b. The other end of the tightening arm 204b is provided with a winding mechanism for retracting and releasing the buffer belt 204c.

[0055] When in use, the oil replenishing tank 100 is transferred to the supporting assembly 200 through the lifting assembly 300, and during the movement, it leans against the side wall of the supporting rod 202 in a leaning manner. During the leaning process of the oil replenishing tank 100, in order to prevent the impact force generated by the tilting collision from being too large, a barrel holding mechanism 204 is provided. When the oil replenishing tank 100 leans, the side wall of the oil replenishing tank 100 contacts one side of the buffer belt 204c, and the buffer belt 204c acts as a buffer to unload the oil replenishing tank 100. Further, under the gravity of the oil replenishing tank 100, the buffer belt 204c is squeezed, so that the buffer belt 204c is unwound and stretched from the winding mechanisms at both ends, and at the same time, the buffer belt 204c pulls the tightening arms 204b on both sides to tighten toward the oil replenishing tank 100, clamping the side wall of the oil replenishing tank 100.

[0056] As a further improvement, two symmetrically structured lifting mechanisms 205 are provided on the transverse stabilizer bar 201 . The lifting mechanisms 205 can contact the bottom of the oil replenishing tank 100 and provide a supporting force for lifting the oil replenishing tank 100 .

[0057] Specifically, the lifting mechanism 205 includes a supporting rod 205a and a hydraulic cylinder 205b, one end of the supporting rod 205a is hinged to the lateral stabilizer bar 201, the cylinder body of the hydraulic cylinder 205b is hinged to the lateral stabilizer bar 201, and the end of the piston rod of the hydraulic cylinder 205b is hinged to the adjacent supporting rod 205a.

[0058] When in use, when the oil replenishing tank 100 is clamped by the caliper mechanism 301 and lifted by the cylinder 302, the piston rod of the hydraulic rod is controlled to extend and retract, driving the supporting rod 205a connected thereto to swing, so that the supporting rod 205a is partially placed under the oil replenishing tank 100 to lift the oil replenishing tank 100.

[0059] The remaining structure is the same as that of Example 2.
