[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural diagram of an embodiment of a stable lifting device, including:

[0034] Please see Figures 1-4 This utility model provides a technical solution:

[0035] A stable lifting device includes a base 1 and a crossbeam 5. The crossbeam 5 has a transverse groove 7 inside. A crossbar 9 is bolted to the inner wall of the transverse groove 7. A motor 6 is bolted to one side of the crossbeam 5. A lead screw 8 is inserted into the output shaft of the motor 6. A slider 10 is sleeved on the outer circumference of the lead screw 8. A lifting block 18 is bolted to the top of the slider 10. A second lifting block 30 is located on one side of the first lifting block 18. Both the first lifting block 18 and the second lifting block 30 have lifting grooves 22 on their inner walls. A lifting rod 23 is damped and connected to the inner wall of the lifting groove 22. The tops of both the first lifting block 18 and the second lifting block 30 are... A vertical block 19 is bolted to the inner wall of the vertical block 19, and a damper 21 is bolted to the inner wall of the vertical block 19. A spring 20 is sleeved on the outer circumference of the damper 21, and a lifting rod 23 is welded to the top of the spring 20. The position of the slider 10 is displaced by the drive motor 6, which makes it easier for the staff to adjust the lifting position of the hook 29 and the clamp 34 according to the actual needs. The structural design of the spring 20 and the damper 21 reduces the possibility of the lifting rod 23 bouncing up, which makes it easier to lift the device and thus improves the overall working efficiency of the device.

[0036] It is worth noting that, in order to better fix the specific angle of the hook 29, one end of the lifting rod 23 is connected to a clamping block 32 via a damping bearing. A clamping plate 34 is bolted to one side of the clamping block 32. An anti-slip pad 31 is glued to one side of the clamping plate 34. The hook 29 is located below the lifting block 20. An installation block 25 is fixed to the top of the hook 29. An installation groove 24 is opened inside the installation block 25. An installation pin 28 is sleeved on the inner wall of the installation groove 24. The angle of the hook 29 is adjusted by rotating the nut 26, which facilitates better fixing of the specific angle of the hook 29, thereby achieving the purpose of hooking the object with the hook 29 and lifting it.

[0037] Next, to better maintain the overall stability of the device, specifically, a short rod 11 is fixed to the top of the slider 10, and a ring 12 is sleeved inside the short rod 11. A steel rope 13 is inserted into the outer circumference of the ring 12, and a roller 16 is sleeved on the outer circumference of the steel rope 13. A locking block 17 is provided on one side of the roller 16, and a guide rod 15 is bolted to the bottom of the locking block 17. A hydraulic cylinder 14 is sleeved on the outer circumference of the guide rod 15. The hydraulic cylinder 14 drives the guide rod 15 to rise and fall, so that the steel rope 13, the roller 16, and the slider 10 form a triangular shape. With the structural design of the clamping plate 34 and the hook 29, the suspended object can achieve a balanced effect during the lifting process, thus making it easier to maintain the overall stability of the device.

[0038] Meanwhile, in order to increase the stability of the device lifting, there are multiple sliders 10, which are symmetrically distributed. The symmetrical distribution of the sliders 10 facilitates the increase of the clamping area, thereby increasing the stability of the device lifting.

[0039] Furthermore, in order to better adjust the specific angle of the clamp, a nut 26 is fitted onto the outer circumference of the mounting pin 28, and the outer circumference of the mounting pin 28 is inserted into one end of the lifting rod 23. A handle 27 is fixed to one end of the mounting pin 28. By driving the handle 27 to rotate the mounting pin 28, the specific angle of the clamp can be adjusted more easily.

[0040] It is worth noting that, in order to maintain the overall balance of the device, the bottom of the hydraulic cylinder 14 is connected to a fixing block 4 by bolts. The fixing block 4 is fitted with a crossbeam 5. The structural design of the fixing block 4 makes it easy to fix the hydraulic cylinder 14 while cooperating with the structural design of the crossbeam 5 to maintain the overall balance of the device.

[0041] Finally, for ease of maintenance, specifically, the bottom of the fixing block 4 is bolted to a guide rod 3, and a hydraulic cylinder 2 is sleeved on the outer circumference of the guide rod 3. The bottom of the hydraulic cylinder 2 is bolted to the base 1. Through the structural design of the hydraulic cylinder 2 and the guide rod 3, it is easy to raise and lower the entire device, thereby achieving the purpose of facilitating maintenance.

[0042] The working principle of a hydraulic cylinder is to achieve mechanical motion through the pressure transmission of hydraulic oil within a sealed cavity. When the hydraulic pump forces oil into one end of the cylinder, the resulting pressure pushes the piston to the other end, thereby driving the guide rod to extend or retract; when oil is supplied in the opposite direction, the piston moves in the opposite direction. By controlling the flow direction and pressure of the oil, precise linear reciprocating motion or force output can be achieved. The magnitude of the power depends on the product of the oil pressure and the effective area of ​​the piston. This is existing technology, and in this article, hydraulic cylinder 1-2, guide rod 1-3, hydraulic cylinder 2-14, and guide rod 2-15 are used as descriptors.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] The device or equipment models mentioned in this article may be as follows:

[0045] Motor: Y802-4.

[0046] Combination Figures 1-4 The stable lifting device of this embodiment is used in the following specific process:

[0047] 1: When using this stable lifting device, the operator moves the device to a suitable position via the base 1, and then drives the hydraulic cylinder 2 to drive the guide rod 3 to lower the crossbeam 5. At this time, the drive motor 6 drives the lead screw 8 to rotate, so that the slider 10 can move the lifting block 18 and the lifting block 20 on the inner wall of the slide groove. This makes it easy to adjust the spacing of the lifting rod 23 and the specific position of the clamping plate 34 and the hook, thus making it suitable for various items to be lifted.

[0048] 2: When the device needs to be lifted by the clamp hook, the operator can rotate the mounting pin 28 by the handle 27, and at the same time, use the threaded connection to remove the nut 26 from the outer circumference of the mounting pin 28. After adjusting the specific angle of the clamp hook and hanging the object, the nut 26 is then fixed to the mounting pin 28 by the threaded connection of the mounting pin 28. When the device needs to be lifted by the clamp plate 34, the operator can hold the lifting rod 23. Through the structural design of the spring 20 and the damper 21, the clamp plate 34 can clamp the object to be lifted. The structural design of the spring 20 and the damper 21 reduces the possibility of the lifting rod 23 bouncing, which makes it easier to lift the device and thus improves the overall working efficiency of the device.

[0049] 3: When the device needs to maintain a good balance during the lifting process, the hydraulic cylinder 214 drives the guide rod 215 to rise and fall, so that the steel rope 13, roller 16 and slider 10 form a triangular shape. With the structural design of the clamping plate 34 and the hook 29, the object being lifted can achieve a balanced effect during the lifting process, thus making it easier to maintain the overall stability of the device.

[0050] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
