[0041] As Figure 1 shown, a hydraulic rod lifting auxiliary tooling in an embodiment of the present invention includes: a vertical plate 2, a rod body 1, a lifting module 6, two rotating shafts 3, and two supporting rods 4;

[0042] A first guide hole 21 extending along a first direction X is formed in the vertical plate 2;

[0043] The rod body 1 extends along a second direction Y and is connected to one side of the vertical plate 2;

[0044] The rotating shafts 3 extend along a third direction Z. Both of the two rotating shafts 3 are sleeved outside the rod body 1 and can move towards or away from each other along the rod body 1. The two rotating shafts 3 are symmetrically distributed with respect to the first guide hole 21;

[0045] The first ends of the two support rods 4 correspond to the two rotating shafts 3 one by one and are rotatably connected. The second ends of the two support rods 4 are hinged through a connecting shaft 5. The connecting shaft 5 is slidably arranged in the first guide hole 21;

[0046] The lifting module 6 is located on the side of the vertical plate 2 facing away from the rod body 1. The lifting module 6 is connected to the connecting shaft 5;

[0047] Wherein, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0048] It should be noted that, in advance, the two rotating shafts 3 are respectively driven to move away from each other along the rod body 1. The rotating shaft 3 drives the first end of the corresponding support rod 4 to rotate around the rotating shaft 3. The two support rods 4 drive the connecting shaft 5 hinged to the second end to descend in the first guide hole 21 along the opposite direction of the first direction X.

[0049] Put the hydraulic rod lifting auxiliary tooling into the cage-shaped support rod 13 of the hydraulic mechanism, and apply the lifting module 6 to the hydraulic rod 12. Drive the two rotating shafts 3 to move towards each other along the rod body 1 respectively. The rotating shaft 3 drives the first end of the corresponding support rod 4 to rotate in the reverse direction around the rotating shaft 3. The two support rods 4 drive the connecting shaft 5 hinged to the second end to gradually rise in the first guide hole 21 along the first direction X. Furthermore, the connecting shaft 5 drives the connected lifting module 6 to rise, and the hydraulic rod 12 acted on by the lifting module 6 is also lifted. The hydraulic rod 12 can be lifted without damaging the cage-shaped support rod 13, and the lifting method is gentle and stable, effectively avoiding damage to the hydraulic rod 12.

[0050] In a more specific embodiment, the lifting module 6 and the connecting shaft 5 are detachably connected.

[0051] It should be noted that when the size of the lifting auxiliary tooling is too large to be directly put into the cage-shaped support rod 13 of the hydraulic mechanism, the lifting module 6 can be first detached from the connecting shaft 5, and the lifting module 6 is put into the cage-shaped support rod 13 of the hydraulic mechanism and acts on the hydraulic rod 12. Then the remaining components are put into the cage-shaped support rod 13, and the lifting module 6 and the connecting shaft 5 are connected.

[0052] Such as Figure 1As shown, in a more specific embodiment, two mounting blocks 7 are sequentially arranged on one side of the vertical plate 2 along the second direction Y. The rod body 1 is a threaded rod 8, and the threaded rod 8 sequentially passes through the two mounting blocks 7. Two sets of threads 81 are provided on the surface of the threaded rod 8 between the two mounting blocks 7. The two sets of threads 81 are sequentially arranged along the second direction and have opposite spiral directions. The two rotating shafts 3 correspond to the two sets of threads 81 one by one and are threadedly connected;

[0053] A second guiding hole 22 extending along the second direction Y is formed in the vertical plate 2, and the first ends of the two rotating shafts 3 are slidably arranged in the second guiding hole 22.

[0054] It should be noted that the threaded rod 8 is rotated in advance so that the two rotating shafts 3 move away from each other along the two sets of threads 81 respectively. The rotating shaft 3 drives the first end of the corresponding support rod 4 to rotate around the rotating shaft 3, and the two support rods 4 drive the connecting shaft 5 hinged to the second end to descend in the first guiding hole 21 in the opposite direction of the first direction X.

[0055] The lifting module 6 is detached from the connecting shaft 5, and the lifting module 6 is placed into the cage-shaped support rod 13 of the hydraulic mechanism and acts on the hydraulic rod 12. The remaining components are placed into the cage-shaped support rod 13, and the lifting module 6 and the connecting shaft 5 are connected.

[0056] The threaded rod 8 is rotated in the reverse direction so that the two rotating shafts 3 move towards each other along the two sets of threads 81 respectively. The rotating shaft 3 drives the first end of the corresponding support rod 4 to rotate in the reverse direction around the rotating shaft 3, and the two support rods 4 drive the connecting shaft 5 hinged to the second end to gradually rise in the first guiding hole 21 along the first direction X. Furthermore, the connecting shaft 5 drives the connected lifting module 6 to rise, and the hydraulic rod 12 acted on by the lifting module 6 is also lifted.

[0057] The first end of the rotating shaft 3 is slidably arranged in the second guiding hole 22, which can prevent the rotating shaft 3 from rotating itself when moving along the threaded rod 8. The second guiding hole 22 can be a continuous guiding hole or two guiding holes arranged at intervals along the second direction Y.

[0058] By controlling the number of rotation turns of the threaded rod 8, the lifting distance of the hydraulic rod 12 can be controlled.

[0059] As Figure 1-3 shown, in a more specific embodiment, it further includes: a limiting plate 9;

[0060] The limiting plate 9 is installed on the side of the two mounting blocks 7 away from the vertical plate 2. A third guiding hole 91 extending along the second direction Y is formed in the limiting plate 9, and the second ends of the two rotating shafts 3 are slidably arranged in the third guiding hole 91.

[0061] It should be noted that the limit plate 9 is installed on the side of the two mounting blocks 7 away from the vertical plate 2, that is, the limit plate 9 is parallel to the vertical plate 2. The third guide hole 91 on the limit plate 9 can be a continuous guide hole or two guide holes arranged at intervals along the second direction Y.

[0062] Both ends of the rotating shaft 3 are slidably connected in the second guide hole 22 and the third guide hole 91 respectively, which improves the stability of the rotating shaft 3 moving along the threaded rod 8.

[0063] As Figure 1-2 shown, in a more specific embodiment, it further includes: a support plate 10, and the support plate 10 is installed at the bottom of the two mounting blocks 7.

[0064] It should be noted that, as Figure 5 shown, the support plate 10 is installed at the bottom of the two mounting blocks 7, so that when the hydraulic mechanism lifting auxiliary tooling is placed into the cage-shaped support rod 13, the support plate 10 can be placed on the platform 14 at the bottom of the cage-shaped support rod 13.

[0065] Since components such as the support plate 10, the mounting block 7, the threaded rod 8, the rotating shaft 3, and the support rod 4 are small in volume or slender, they can be placed in the space inside the narrow cage-shaped support rod 13, effectively overcoming the limitation of space.

[0066] The side of the support plate 10 close to the lifting module 6 is an arc-shaped edge, which can bypass the lifting module 6 to avoid interference, and the widths of both ends of the support plate 10 are larger, which can better support on the platform 14.

[0067] As Figure 1-2 shown, in a more specific embodiment, the lifting module 6 includes: a connecting member 62 and a supporting plate 63;

[0068] The connecting member 62 is located on the side of the vertical plate 2 facing away from the rod body 1, and the connecting member 62 is connected to the connecting shaft 5;

[0069] The supporting plate 63 is perpendicular to the first direction X, and the supporting plate 63 is connected to the bottom end of the connecting member 62 on the side away from the vertical plate 2.

[0070] It should be noted that since the movement of the lifting module 6 is rising along the first direction X, the lifting direction of the hydraulic rod 12 is the first direction X. The supporting plate 63 is perpendicular to the first direction X and is connected to the bottom end of the connecting member 62 on the side away from the vertical plate 2, and the supporting plate 63 can be placed under the bottom of the hydraulic rod 12 (the bottom of the hydraulic rod 12 is a flange), so that when the connecting member 62 rises along with the connecting shaft 5, the supporting plate 63 can lift the hydraulic rod 12.

[0071] The supporting plate 63 is connected to the bottom end of the connecting member 62 on the side away from the vertical plate 2, which can avoid hitting components such as the rod body 1 during lifting.

[0072] In another more specific embodiment, the lifting module 6 clamps the hydraulic rod 12, so that when the lifting module 6 rises, the hydraulic rod 12 is lifted.

[0073] As Figure 1-2 shown, in a more specific embodiment, the connecting member 62 includes: a connecting plate 621 and a fork plate 622;

[0074] The connecting plate 621 is located on the side of the vertical plate 2 facing away from the rod body 1. The connecting plate 621 extends along the first direction X, and the connecting plate 621 is connected to the connecting shaft 5;

[0075] The fork plate 622 includes two fork portions 6221. One ends of the two fork portions 6221 are connected and perpendicularly connected to the bottom end of the connecting plate 621 on the side away from the vertical plate 2. A clamping interface 6222 for clamping the hydraulic rod 12 is defined between the two fork portions 6221, and the support plate 63 is connected to the bottoms of the two fork portions 6221.

[0076] It should be noted that the support plate 63 is connected to the bottoms of the two fork plates 622. When the support plate 63 is placed below the bottom of the hydraulic rod 12, the hydraulic rod 12 is clamped in the clamping interface 6222 formed between the two fork portions 6221, and the position between the lifting module 6 and the hydraulic rod 12 is more stable, so that the hydraulic rod 12 can be lifted more stably.

[0077] The two fork portions 6221 are detachably connected to the connecting plate 621, and fork portions 6221 of different sizes can be replaced to adapt to hydraulic rods 12 of different sizes.

[0078] The support plate 63 is detachably connected to the bottoms of the two fork portions 6221. Specifically, the support plate 63 and the fork portions 6221 can be connected by M8 hexagon socket head cap screws, so that support plates 63 of different sizes can be replaced or repaired. And the support plate 63 can be first disassembled and placed into the bottom of the hydraulic rod 12 in the cage-shaped support rod 13, and then other components can be installed. After the lifting is completed, the components can be removed in sequence.

[0079] The connecting plate 621 is a long strip plate extending along the first direction X, which is convenient to be placed into the narrow space in the cage-shaped support rod 13, effectively overcomes the space limitation, and is beneficial to improving the flexibility and convenience of operation.

[0080] As Figure 2 、 4 shown, in a more specific embodiment, a plurality of connecting holes 61 are formed in the lifting module 6 and arranged in sequence along the first direction X, and the connecting shaft 5 passes through one of the connecting holes 61.

[0081] It should be noted that the connecting shaft 5 can be selectively passed through one of the connecting holes 61 to adjust the relative position between the lifting module 6 and the vertical plate 2 to adapt to the height of the hydraulic rod 12 required for specific application.

[0082] Since the length of the first guide hole 21 is limited, the distance that the hydraulic rod 12 can be lifted is also limited. When it is necessary to lift to a higher height and the position of the vertical plate 2 is fixed, the connecting shaft 5 can select a connecting hole 61 of a suitable height to pass through, so that the lifting module 6 can better act on the hydraulic rod 12.

[0083] When the lifting module 6 includes a connecting member 62 and a supporting plate 63 , a plurality of connecting holes 61 sequentially arranged along the first direction X are formed on the connecting member 62 .

[0084] When the connecting member 62 includes a connecting plate 621 and a fork plate 622 , a plurality of connecting holes 61 sequentially arranged along the first direction X are formed on the connecting plate 621 .

[0085] like Figure 2 , 4 As shown, in a more specific embodiment, the connecting hole 61 is a threaded hole, the connecting shaft 5 includes a tubular shaft 51 and a sliding screw 52, the second ends of the two struts 4 are hinged through the tubular shaft 51, and a sliding screw 52 is installed in the tubular shaft 51, and the sliding screw 52 passes through one of the connecting holes 61.

[0086] It should be noted that the connecting hole 61 is a threaded hole, the connecting shaft 5 includes a tubular shaft 51 and a sliding screw 52, the second ends of the two support rods 4 are hinged through the tubular shaft 51, and a sliding screw 52 is installed in the tubular shaft 51. The sliding screw 52 passes through one of the connecting holes 61. The connection between the sliding screw 52 and the threaded connecting hole 61 is more stable, which can improve the stability of the connection between the connecting shaft 5 and the lifting module 6.

[0087] The sliding screw 52 is preferably an M8 hexagon socket screw.

[0088] like Figure 1 , 3 As shown, in a more specific embodiment, the threaded rod 8 passes through two mounting blocks 7 and is respectively connected to a rotating handle 11 at both ends.

[0089] It should be noted that in order to facilitate the staff to manually rotate the threaded rod 8, rotating handles 11 are respectively connected to the two ends of the threaded rod 8 passing through the two mounting blocks 7. When in use, two staff members grasp the rotating handles 11 and rotate the threaded rod 8 synchronously, which is more labor-saving.

[0090] like Figure 3-4 As shown, in a more specific embodiment, the rotating handle 11 includes: a fixed shaft 111 and a gripping portion 112;

[0091] The fixed shaft 111 and the threaded rod 8 are coaxially connected, and the holding part 112 is connected to the fixed shaft 111.

[0092] It should be noted that the fixed shaft 111 and the threaded rod 8 are coaxially connected, and the holding part 112 is connected to the fixed shaft 111. Thus, when the staff holds the holding part 112, the threaded rod 8 can be driven to rotate better.

[0093] The working process of the present invention is as follows: Two rotating shafts 3 are driven to move away from each other along the rod body 1 in advance. The rotating shafts 3 drive the first ends of the corresponding support rods 4 to rotate around the rotating shafts 3. The two support rods 4 drive the connecting shaft 5 hinged to the second ends to descend in the first guiding hole 21 in the opposite direction of the first direction X.

[0094] The hydraulic rod lifting auxiliary tooling is placed into the support rod 13 of the cage type of the hydraulic mechanism, and the lifting module 6 acts on the hydraulic rod 12. The two rotating shafts 3 are driven to move towards each other along the rod body 1. The rotating shafts 3 drive the first ends of the corresponding support rods 4 to rotate in the opposite direction around the rotating shafts 3. The two support rods 4 drive the connecting shaft 5 hinged to the second ends to gradually rise in the first guiding hole 21 along the first direction X. Then, the connecting shaft 5 drives the connected lifting module 6 to rise, and the hydraulic rod 12 acted on by the lifting module 6 is also lifted.

[0095] In summary, the embodiment of the present invention provides a hydraulic rod lifting auxiliary tooling, which can realize the lifting of the hydraulic rod without damaging the support rod of the cage type, and the lifting method is gentle and stable, effectively avoiding damage to the hydraulic rod.

[0096] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
