Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, and in particular to a lifting device for fossil specimens. Background Technology

[0002] Traditional lifting equipment is typically designed for materials with regular shapes and hard textures, employing a rigid clamping and support method. However, fossil specimens are often irregularly shaped and fragile, making them highly susceptible to localized breakage or damage when lifted directly using such equipment. While some flexible lifting tools have attempted to address this issue, in practical applications, they still struggle to automatically adjust the support angle according to the complex contours of fossil skeletons. Furthermore, they lack reliable self-locking mechanisms during lifting, resulting in insufficient support stability and an inability to effectively prevent specimen swaying or slippage, thus compromising lifting safety and specimen integrity.

[0003] Therefore, there is an urgent need for a specialized lifting device that can adapt to the shape of the skeleton, provide flexible support, and has self-locking capability. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a lifting device for fossil specimens.

It also includes an adaptation mechanism disposed on the lifting frames for flexibly supporting and limiting the fossil specimen skeleton. The adaptation mechanism includes a portal frame A fixedly connected to the lifting frames, a portal frame B slidably connected to the inner cavity of the portal frame A, a tension spring A between the portal frame A and the portal frame B, and a shaped block slidably connected to the portal frame B. A compression spring A is disposed between the shaped block and the portal frame B. Sliding blocks A are symmetrically slidably connected within the shaped block, and a compression spring B is disposed between the sliding blocks A and the shaped block. A bearing plate is rotatably connected between two sliding blocks A. A flexible pad for supporting the fossil skeleton is fixedly attached to the bearing plate. A locking component for locking the bearing plate is provided on the shaped block.

[0008] In a preferred embodiment of the present invention, the locking assembly includes a slotted ring symmetrically fixedly sleeved on the rotating shaft of the bearing plate, and a locking block fixedly connected to the irregular block and located below the slotted ring. The locking block can be embedded in the slotted ring to restrict the rotation of the bearing plate.

[0009] In a preferred embodiment of the present invention, in order to further secure the fossil skeleton on the basis of flexible support, the portal frame B is provided with a fastening mechanism, which includes sliders B symmetrically slidably connected inside the portal frame B, and a fixing strap that is fixedly connected between the two sliders B.

[0010] In a preferred embodiment of the present invention, the fastening mechanism further includes a rack A symmetrically slidably connected to the gantry frame B, a tension spring B is provided between the rack A and the slider B, and a gear meshing with the rack A is symmetrically rotatably connected to the gantry frame B; a rack B meshing with the gear is symmetrically fixed inside the gantry frame A.

[0011] In a preferred embodiment of the present invention, the fastening mechanism further includes two sets of slotted blocks fixed to the slider B, a locking pin B slidably connected in the slotted block, a tension spring C provided between the locking pin B and the slotted block, and two sets of vertical rods symmetrically fixed to the gantry frame B, the vertical rods having locking grooves B that match the locking pins B.

[0012] In a preferred embodiment of the present invention, two sets of drive rods are fixedly connected inside the gantry frame A, and a convex shaft is fixedly connected to the locking pin B. The convex shaft is slidably connected to the slotted block and slidably cooperates with the drive rods.

[0013] In a preferred embodiment of the present invention, the drive rod is L-shaped, and the inclined surface and the vertical surface of the L-shape are used for pressing and limiting the convex shaft, respectively.

[0014] In a preferred embodiment of the present invention, a pull ring is fixedly connected to the card block, and the pull ring is slidably connected to the portal frame B through the block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

Detailed Implementation

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Example 1

[0021] A lifting device for fossil specimens, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, it includes a hanger 1 and four lifting frames 201 that are equidistantly distributed and slidably mounted on the hanger 1. An adaptation mechanism is provided below the lifting frames 201. The adapting mechanism includes a gantry frame A202 fixed to the bottom end of the lifting frame 201, a gantry frame B203 slidably connected to the inner wall of the gantry frame A202, a tension spring A connecting the top of the inner wall of the gantry frame A202 and the top of the gantry frame B203, a shaped block 204 slidably connected to the gantry frame B203 through the gantry frame, and a compression spring A between the shaped block 204 and the front side of the gantry frame B203; Two sliders A205 are symmetrically slidably installed inside the irregular block 204 along the vertical direction. A compression spring B is provided between the bottom of each slider A205 and the inner wall of the irregular block 204. The two sliders A205 that are opposite to each other are rotatably connected to a support plate 206. A flexible pad 207 is fixed to the top surface of the support plate 206. The irregular block 204 is also provided with a locking assembly, which includes a slotted ring 501 symmetrically fixed on the rotating shaft of the bearing plate 206, and a locking block 502 fixed on the irregular block 204, with the locking block 502 located directly below the slotted ring 501.

[0022] like Figure 3 and Figure 4 As shown, it also includes a lifting adjustment mechanism disposed between the hanger 1 and the lifting frame 201. The lifting adjustment mechanism includes a screw 301 threadedly connected to the lifting frame 201. The screw 301 is rotatably connected to the bottom surface of the hanger 1. An electric push rod 302 is installed on the hanger 1 and a sliding frame 303 is slidably connected in the horizontal direction. The telescopic end of the electric push rod 302 is fixedly connected to the sliding frame 303. Four sets of locking pins A304 are fixedly connected on the sliding frame 303, with two in each set. Two rows of locking grooves A that match the locking pins A304 are opened on the left side of each of the four lifting frames 201.

[0023] like Figure 5As shown, in order to lock the position of the irregular block 204, a locking block 401 is slidably connected in the vertical direction inside the portal frame B203. A compression spring C is provided between the bottom of the locking block 401 and the inner wall of the portal frame B203. The bottom surface of the irregular block 204 is provided with a slot that matches the top inclined surface of the locking block 401. A pull ring 1001 is fixedly connected to the bottom of the locking block 401. The pull ring 1001 slides through and extends to the lower side of the portal frame B203.

[0024] like Figure 7 As shown, a fastening mechanism is provided inside the portal frame B203. The fastening mechanism includes two sliders B601 that are symmetrically slidably connected inside the portal frame B203. A fixing strap 602 is fixedly connected between the two sliders B601.

[0025] like Figure 8 As shown, the fastening mechanism also includes a rack A701 that is symmetrically slidably connected to the front and rear of the gantry frame B203. A tension spring B is connected between the rack A701 and the bottom of the adjacent slider B601. Gears 702 are symmetrically rotatably mounted on the front and rear sides of the gantry frame B203. Gears 702 mesh with rack A701. Racks B703 are symmetrically fixed to the front and rear sides of the inner wall of the gantry frame A202. Racks B703 and gears 702 mesh with each other.

[0026] like Figure 8 and Figure 9 As shown, two sets of slotted blocks 801 are fixedly connected to the bottom of the slider B601, with two blocks in each set. Locking pins B802 are slidably connected inside the slotted blocks 801. A tension spring C is provided between the locking pins B802 and the inner wall of the slotted blocks 801. Two sets of vertical rods 803 are fixedly connected to the front and rear sides of the gantry frame B203, with two rods in each set. A row of locking grooves B that match the locking pins B802 is opened on the vertical rods 803.

[0027] like Figure 10 As shown, two sets of L-shaped drive rods 901 are fixed to the front and rear sides of the inner wall of the portal frame A202, with two rods in each set. A convex shaft is fixed to the outer wall of the locking pin B802. The convex shaft is slidably connected to the slotted block 801 and can contact the inclined or vertical surface of the drive rod 901.

[0028] In the initial state, the tops of the four lifting frames 201 are on the same horizontal plane, and tension spring A, compression spring A, compression spring B, tension spring B and tension spring C are all in the released state. First, the staff manually rotates the four lead screws 301 according to the relative positions of the different bones of the fossil specimen. The rotation of the lead screws 301 drives the corresponding lifting frame 201 to move downward until the four portal frames B203 cover the outside of the corresponding bones, and the top surfaces of the four flexible pads 207 are exactly located on the underside of the fossil bones. After the adjustment is completed, the staff starts the electric push rod 302.

[0029] Step 1: Initial Altitude Lock The telescopic end of the electric push rod 302 extends outward, causing the sliding frame 303 to slide to the right. The sliding frame 303 drives the four sets of locking pins A304 on it to move to the right in sync, so that the four sets of locking pins A304 are precisely inserted into the locking grooves A on the sides of the four lifting frames 201, so that the lifting frame 201 is completely limited at this time and can no longer move vertically.

[0030] Step 2: Flexible support preloading Next, the staff pushes the four irregular blocks 204 one by one. Taking one of the irregular blocks 204 as an example, after being subjected to force, the irregular block 204 slides backward along the portal frame B203, thereby compressing the compression spring A to store energy. The irregular block 204 drives the bearing plate 206 and the flexible pad 207 to move backward synchronously through the slider A205. During the movement, the bottom surface of the irregular block 204 contacts the inclined surface of the locking block 401, squeezing the locking block 401 to slide downward, thereby causing the compression spring C to store energy. When the irregular block 204 slides to the predetermined position, the slot at its bottom is exactly aligned with the locking block 401. At this time, the compression spring C releases energy instantly, pushing the locking block 401 upward to reset, so that it is locked into the slot. The irregular block 204 is locked and cannot move forward or backward anymore.

[0031] Step 3: Adaptive Fitting and Rigid Locking Then, the entire control frame 1 is raised upwards. The control frame 1 drives the lifting frame 201, the gantry frame A202, and the gantry frame B203 to move upwards. The irregular block 204 and the flexible pad 207 rise with the gantry frame B203. When the flexible pad 207 contacts the curved surface of the fossil specimen's skeleton, the flexible pad 207 is compressed by the shape of the skeleton, causing the support plate 206 to rotate, so that the flexible pad 207 fits the skeleton to the maximum extent. When the flexible pad 207 fits tightly with the skeleton and can no longer rise, the support plate 206 stops rising. As the control frame 1 continues to rise, the gantry frame B203 drives the irregular block 204 to continue to rise. At this time, the slider A205 cannot continue to rise due to the influence of the support plate 206, causing the compression spring B to be compressed and stored. Then, the locking block 502 is locked into the slotted ring 501, completely locking the support plate 206 and preventing any further rotation, thus providing a stable and fitting basic support force for the fossil specimen.

[0032] Step 4: Automatic tightening of the binding When the support plate 206 is locked, the resistance of the fossil skeleton causes the portal frame B203 to stop rising, resulting in relative displacement between the portal frames A202 and B203. The tension spring A extends under stress, and the portal frame A202 moves the rack B703 upward. The rack B703, through the gear 702, drives the rack A701 to slide downward along the portal frame B203. As the rack A701 descends, it drives the slider B601 to slide downward along the portal frame B203 via the tension spring B. Both sliders B601 together cause the fixing strap 602 to fall until it is tightly pressed against and taut on the outside of the fossil skeleton. After the fixing strap 602 is taut, the slider B601 can no longer slide downward, and the rack A701 continues to slide downward... The extension of the tension spring B provides continuous flexible tension to the fixing strap 602. As the slider B601 descends, it drives the slotted block 801 on it to descend synchronously. During this process, the convex shaft on the locking pin B802 contacts the inclined surface of the adjacent drive rod 901. As it continues to descend, the inclined surface of the drive rod 901 squeezes the convex shaft, causing the locking pin B802 to overcome the resistance of the tension spring C and extend outward from the slotted block 801. When the convex shaft slides to the vertical surface of the L-shaped drive rod 901, the locking pin B802 inserts into the corresponding locking groove B on the vertical rod 803, keeping the fixing strap 602 taut. During subsequent hoisting and transportation, the support of the flexible pad 207 and the tight pressure of the fixing strap 602 effectively prevent the fossil specimen from shaking and causing bone misalignment or damage.

[0033] Step 5: Lifting, Repositioning, and Unlocking After the fossil specimen is hoisted to the target position, the control frame 1 is lowered, and the gantry frame A202 moves downward relative to the gantry frame B203. The tension spring A gradually contracts, and the gantry frame A202 drives the rack B703 to descend synchronously. The rack B703 drives the rack A701 to slide upward along the gantry frame B203 through the gear 702. At this time, the locking pin B802 is still inserted in the locking groove B of the vertical rod 803, and the slider B601 is locked to the gantry frame B203 through the slotted block 801 and the locking pin B802, and cannot rise. Therefore, the rise of the rack A701 only causes the tension spring B to gradually contract from the stretched state. At the same time, the gantry frame A202 drives the drive rod. 901 descends synchronously, while the convex shaft on the locking pin B802 remains stationary with the slider B601. The convex shaft slides upward relative to the drive rod 901 along its L-shaped vertical surface. When the convex shaft passes the top of the vertical surface of the drive rod 901, the tension spring C immediately contracts, pulling the locking pin B802 back into the slotted block 801, causing it to disengage from the locking groove B of the vertical rod 803, thus completing the automatic unlocking. After the locking pin B802 is unlocked, the slider B601 regains its freedom, and the rack A701 continues to rise, driving the slider B601 to slide upward along the portal frame B203 through the tension spring B. The two sliders B601 together drive the fixing belt 602 to rise, causing the fixing belt 602 to loosen.

[0034] When tension spring A is fully contracted, gantry frame A202 drives gantry frame B203 to descend via tension spring A. Compression spring B is gradually released, and flexible pad 207 remains in contact with the fossil skeleton. Gantry frame B203 drives locking block 502 to descend via irregular block 204, causing locking block 502 to disengage from groove ring 501. Support plate 206 returns to a free rotation state. When compression spring B is fully released, irregular block 204 drives flexible pad 207 to descend and detach from the fossil skeleton via compression spring B, slider A205, and support plate 206. The worker pulls down pull ring 1001, which drives locking block 401 to slide downward. Compression spring C contracts and stores energy. After locking block 401 slides out of the slot of irregular block 204, compression spring A releases energy and pushes irregular block 204 forward to reset. Then, pull ring 1001 is released, and compression spring C releases energy to drive locking block 401 to reset. Locking block 401 drives pull ring 1001 to reset.

[0035] Finally, the telescopic end of the control electric push rod 302 retracts, thereby pulling the sliding frame 303 to slide to the left, causing the four sets of locking pins A304 to exit the corresponding locking grooves A, thus completing the reset of the entire device.
