Description

Technical Field

[0001] This invention relates to the field of gear lifting equipment technology, specifically an automatic gripping and releasing gear lifting equipment. Background Technology

[0002] Current gear lifting devices (such as Figure 1 , Figure 2 Although the operation has been simplified to a considerable extent, manual operation of the lifting equipment is still required to complete the pre- and post-lifting preparations. The current operating steps are as follows:

[0003] 1. First, lift the gear lifter into the appropriate position inside the gear (e.g., Figure 1 );

[0004] 2. Manually pull out the push-pull pin to lower the lifting platform and extend the suspension legs (e.g., Figure 2 );

[0005] 3. After hoisting the gear to the desired position, the lifting platform needs to be manually pressed down to retract the suspension.

[0006] Therefore, based on its many years of experience in design, development and actual manufacturing in the relevant industry, the applicant has studied and improved the existing structure and its shortcomings, and provides an automatic gripping and releasing gear lifting device and its usage method, in order to achieve a more practical purpose. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides an automatic gripping and releasing gear lifting device and its usage method, solving the problem of direct manual contact during gear lifting device operation.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention provides the following technical solution: an automatic gripping and releasing gear lifting device, comprising a suspension rod, a hinged plate connected to the lower end of the suspension rod, a lifting plate sleeved on the suspension rod, a suspension leg hinged to the lifting plate, a connecting rod hinged to the hinged plate, the other end of the connecting rod hinged to the bent portion of the suspension leg, a push-pull pin provided on the lifting plate, a hole provided on the suspension rod to cooperate with the push-pull pin, an L-shaped support leg sleeved on the suspension rod, a push-pull rod hinged to the L-shaped support leg, the other end of the push-pull rod contacting the handle of the push-pull pin, and a crossbar provided on the top of the lifting plate.

[0011] Preferably, a damping rod is hinged to the L-shaped support leg, and the other end of the damping rod is hinged to the middle section of the push-pull rod.

[0012] Preferably, the suspension rod is provided with a fixing plate, which can restrict the position of the L-shaped support leg.

[0013] Preferably, the lower end of the L-shaped support leg is provided with a locking slot.

[0014] Preferably, the crossbar is a telescopic bar.

[0015] Preferably, the horizontal section of the L-shaped support leg is a telescopic rod.

[0016] Preferably, the other end of the push-pull rod is magnetically connected to the handle of the push-pull pin.

[0017] Preferably, the other end of the push-pull rod is adhesively connected to the handle of the push-pull pin.

[0018] Preferably, the lower end of the suspension leg is provided with a suspension foot.

[0019] A method for using an automatic gripping gear lifting device includes a gear and a crane. The gear has a suspension flange on its inner wall, and the crane's cable is connected to the upper end of a suspension rod. The method includes the following steps:

[0020] Step 1: After operating the crane to position the gear lifting device directly above the gear, make the lower end of the L-shaped support leg of the gear lifting device contact the upper end of the gear.

[0021] Step 2: Operate the crane to lower the gear lifting device vertically until the handle of the push-pull rod separates from the handle of the push-pull pin. At this time, since the handle of the push-pull pin is pulled to the left end by the push-pull rod, the push-pull pin extends completely out of the suspension rod. After the lifting plate is no longer restricted by the suspension rod, it moves downward relative to the suspension rod and unfolds the suspension legs and connecting rod. The lower end of the suspension legs is locked at the bottom of the suspension flange, ready for lifting.

[0022] Step 3: Operate the crane to lift the gear lifting device and gear to the required placement position;

[0023] Step 4: Operate the crane to move the gear lifting device vertically downwards until the crossbar contacts the upper end of the gear;

[0024] Step 5: Operate the crane to continue moving the gear lifting device downwards until the suspension legs and connecting rods retract again;

[0025] Step Six: Operate the crane to raise the gear lifting device vertically until the push-pull rod contacts the handle of the push-pull pin;

[0026] Step 7: Operate the crane to raise the gear lifting device until it contacts the upper end of the fixed plate and the L-shaped support leg;

[0027] Step 8: Operate the crane to continue raising the gear lifting device until the lower end of the L-shaped support leg separates from the gear.

[0028] (III) Beneficial Effects

[0029] This invention provides an automatic gripping and releasing gear lifting device and its method of use. It has the following beneficial effects:

[0030] This automatic gripping gear lifting device and its usage method utilize a contact-connected push-pull rod to operate the push-pull pin's movement, enabling horizontal movement within a vertical motion. This, in turn, allows control of the lifting plate within the gear lifting device. Furthermore, a crossbar is installed at the top of the lifting plate, which can increase the distance between the lifting plate and the transfer plate by allowing the gear lifting device to continue moving downwards, thereby achieving the folding of the gear lifting device.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1: The most basic unit for realizing the function of this invention

[0046] An automatic gripping and releasing gear lifting device includes a suspension rod 1, a hinge plate 2 connected to the lower end of the suspension rod 1, a lifting plate 3 sleeved on the suspension rod 1, a suspension leg 4 hinged to the lifting plate 3, a connecting rod 5 hinged to the hinge plate 2, the other end of the connecting rod 5 hinged to the bent part of the suspension leg 4, a push-pull pin 31 provided on the lifting plate 3, a hole provided on the suspension rod 1 to cooperate with the push-pull pin 31, an L-shaped support leg 6 sleeved on the suspension rod 1, a push-pull rod 7 hinged to the L-shaped support leg 6, the other end of the push-pull rod 7 contacting the handle of the push-pull pin 31, and a crossbar 32 provided on the top of the lifting plate 3.

[0047] Example 2: To make the push-pull rod 7 hover in the air

[0048] The difference from Embodiment 1 is that a damping rod 8 is hinged to the L-shaped support leg 6, and the other end of the damping rod 8 is hinged to the middle section of the push-pull rod 7.

[0049] In practice, the limiting telescopic rod can be used in place of the damping rod 8. However, since the limiting telescopic rod does not have strong control over the suspension position of the push-pull rod 7, it is not recommended to use it in order to increase the overall machining accuracy of this gear lifting tool.

[0050] Example 3: In order to enable the suspension rod 1 to lift the L-shaped support leg 6

[0051] The difference from Embodiment 1 is that a fixing plate 11 is provided on the suspension rod 1, which can restrict the position of the L-shaped support leg 6.

[0052] The optimal setting position of the fixed plate 11 is such that, after unhooking and before the L-shaped support leg 6 is lifted, the push-pull rod 7 can push the push-pull pin 31 into the hole on the suspension rod 1.

[0053] Example 4: To make the contact between the L-shaped support leg 6 and the gear 9 more stable

[0054] The difference from Embodiment 1 is that the lower end of the L-shaped support leg 6 is provided with a latch 61.

[0055] To further enhance adaptability to gears with different wall thicknesses, the bayonet 61 can also be configured to have an adjustable opening.

[0056] Example 5: To increase the adaptability of the present invention to gears of different diameters.

[0057] The difference from Example 1 is that the crossbar 32 is a telescopic bar.

[0058] Example 6: To increase the adaptability of the present invention to gears of different diameters.

[0059] The difference from Example 1 is that the horizontal section of the L-shaped support leg 6 is a telescopic rod.

[0060] Example 7: A connection method between push-pull rod 7 and push-pull pin 31 handle

[0061] The difference from Embodiment 1 is that the other end of the push-pull rod 7 is magnetically connected to the handle of the push-pull pin 31.

[0062] Example 8: Another connection method between push-pull rod 7 and push-pull pin 31 handle

[0063] The difference from Example 1 is that the other end of the push-pull rod 7 is adhesively connected to the handle of the push-pull pin 31.

[0064] The connection methods used in Embodiments 7 and 8 are, firstly, to facilitate the separation and connection of the push-pull rod 7 and the handle of the push-pull pin 31, and secondly, to enable the push-pull rod 7 to pull the handle of the push-pull pin 31 to the left end.

[0065] Example 9: To enhance the stability of the gear lifting device and gear 9 during lifting.

[0066] The difference from Embodiment 1 is that the lower end of the suspension leg 4 is provided with a suspension foot 41.

[0067] Example 10: Method of using the gear lifting device of the present invention

[0068] The system includes a gear 9 and a crane. A suspension flange 91 is provided on the inner wall of the gear 9. The crane cable is connected to the upper end of the suspension rod 1. The system includes the following steps:

[0069] Step 1: After operating the crane to position the gear lifting device directly above the gear 9, make the lower end of the L-shaped support leg 6 of the gear lifting device contact the upper end of the gear 9.

[0070] Step 2: Operate the crane to lower the gear lifting device vertically until the handle of the push-pull rod 7 separates from the handle of the push-pull pin 31. At this time, since the handle of the push-pull pin 31 is pulled to the left end by the push-pull rod 7, the push-pull pin 31 extends completely out of the suspension rod 1. After the lifting plate 3 is no longer restricted by the suspension rod 1, it moves downward relative to the suspension rod 1 and unfolds the suspension leg 4 and connecting rod 5. The lower end of the suspension leg 4 is locked at the bottom of the suspension flange 91, ready for lifting.

[0071] Step 3: Operate the crane to lift the gear lifting device and gear 9 to the required placement position;

[0072] Step 4: Operate the crane to move the gear lifting device vertically downwards until the crossbar 32 contacts the upper end of the gear 9;

[0073] Step 5: Operate the crane to continue moving the gear lifting device downwards until the suspension leg 4 and connecting rod 5 are retracted again;

[0074] Step 6: Operate the crane to raise the gear lifting device vertically until the push-pull rod 7 contacts the handle of the push-pull pin 31;

[0075] Step 7: Operate the crane to raise the gear lifting device until it contacts the upper end of the fixed plate 11 and the L-shaped support leg 6;

[0076] Step 8: Operate the crane to continue raising the gear lifting device until the lower end of the L-shaped support leg 6 separates from the gear 9.

[0077] In summary, this automatic gripping gear lifting device and its usage method utilize a contact-connected push-pull rod to operate the push-pull pin's movement, achieving horizontal movement within a vertical motion, thereby controlling the lifting plate within the gear lifting device. Furthermore, a crossbar is installed at the top of the lifting plate, which can increase the distance between the lifting plate and the transfer plate by allowing the gear lifting device to continue moving downwards, thus enabling the folding of the gear lifting device.
