If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figures 1 to 4 A titanium alloy wide and thick plate lifting device according to an embodiment of the utility model comprises a plurality of lifting units 100, which are connected in sequence to form the lifting device of this embodiment; the maximum length of a single lifting unit 100 is a fixed value, and the number of lifting units 100 to be installed can be accurately calculated according to the length of the titanium alloy wide and thick plate, thereby improving the lifting efficiency; in addition, the lifting device is formed by connecting a plurality of identical lifting units 100 in sequence, which is convenient for maintenance and reduces maintenance costs.

[0037] In an embodiment of the utility model, the lifting unit 100 includes a first telescopic structure 200 and two second telescopic structures 300 arranged at intervals, and the two second telescopic structures 300 are respectively connected to the two ends of the first telescopic structure 200, that is, the length adjustment of the first telescopic structure 200 can drive the change of the spacing between the two second telescopic structures 300; the lifting unit 100 can realize the change of the lifting device in the length direction through the second telescopic structure 300, and can realize the change of the lifting device in the width direction through the first telescopic structure 200, so that it is suitable for the lifting of titanium alloy wide and thick plates of various lengths and widths.

[0038] Furthermore, a support plate 351 is provided on the lower surface of the second telescopic structure 300, and the support plate 351 is used to place the titanium alloy wide and thick plate; a connection seat 360 is provided on the upper surface of the second telescopic structure 300, and the connection seat 360 is used to connect the sling 400, and the sling 400 is used to connect to the crane; the two ends of the sling 400 are respectively connected to the connection seats 360 of the two second telescopic structures 300. For details, refer to Figure 2 As shown, the second telescopic structure 300 is provided with a vertical plate 350 extending downward, a support plate 351 is installed at the end of the vertical plate 350, and a diagonal tie rod 352 is provided at the bottom of the support plate 351. The vertical plate 350 is preferably fixedly connected to the lower surface or side of the second telescopic structure 300, for example, by welding or bolts; the support plate 351 is arranged horizontally, and the horizontally arranged support plate 351 can stably support the titanium alloy wide and thick plate, so that the lifting and transfer of the titanium alloy wide and thick plate is more stable; because the support plate 351 is arranged horizontally, the diagonal tie rod 352 is arranged at the bottom of the support plate 351, which can improve the support strength of the support plate 351 and extend the service life of the support plate 351. A buffer layer can be provided on the surface of the support plate 351, and the buffer layer is made of rubber or other materials, so as to avoid damage to the surface of the titanium alloy wide and thick plate.

[0039] In the embodiment of the utility model, a lifting structure 500 is also included, and the lifting structure 500 is slidably installed on the sling 400 for connecting with the crane. It can be imagined that most of the crane ends are hooks at present. In theory, there is no need to set the lifting structure 500, and the sling 400 can be directly hung on the hook to achieve lifting. However, the reality is that when the hook is lifting the titanium alloy wide and thick plate, the hook sometimes cannot be accurately located in the middle position of the sling 400, so when the crane is lifting the titanium alloy wide and thick plate, the titanium alloy wide and thick plate will have different heights on both sides in the width direction, which poses a greater lifting risk; and the lifting structure 500 is easier to slide along the sling 400, so the hook and the sling 400 are indirectly connected through the lifting structure 500, which can make the hook easier to be located in the middle position of the sling 400 when lifting the titanium alloy wide and thick plate, thereby maintaining the stable lifting of the titanium alloy lifting plate.

[0040] In an embodiment of the utility model, the first telescopic structure 200 includes a first fixed rod 210, a first movable rod 220, a first screw rod and a first driving member 230. The first screw rod is installed on the first fixed rod 210, and the first movable rod 220 is slidably installed on the first fixed rod 210 and is connected to the first screw rod in a transmission manner. The first driving member 230 is used to drive the first screw rod to rotate around its own axis, and the rotation of the first screw rod can drive the first movable rod 220 to slide relative to the first fixed rod 210. Specifically, the first fixed rod 210 is provided with a first through hole axially penetrating the first fixed rod 210, the first screw rod is installed in the first through hole, and the first movable rod 220 is penetrated in the first through hole; the first driving member 230 is installed on the outer surface of the first fixed rod 210, and the first driving member 230 is connected to the first screw rod through a transmission member. The first driving member 230 is a belt or a chain.

[0041] It should be understood that the second telescopic structure 300 is substantially the same as the first telescopic structure 200, the main difference being that the second telescopic structure 300 is provided with a vertical plate 350 and a connecting seat 360 and other structures. Figure 3 As shown, the second telescopic structure 300 includes a second fixed rod 310, a second movable rod 320, a second screw rod 330 and a second driving member 340. The second screw rod 330 is installed on the second fixed rod 310, and the second movable rod 320 is slidably installed on the second fixed rod 310 and is transmission-connected with the second screw rod 330; the second driving member 340 is used to drive the second screw rod 330 to rotate around its own axis, and the rotation of the second screw rod 330 can drive the second movable rod 320 to slide relative to the second fixed rod 310. Similarly, the second fixed rod 310 is provided with a second through hole 311 axially penetrating the second fixed rod 310, the second screw rod 330 is installed in the second through hole 311, and the second movable rod 320 is penetrated in the second through hole 311; the second driving member 340 is installed on the outer surface of the second fixed rod 310, and the second driving member 340 is connected to the second screw rod 330 through a transmission member. The second driving member 340 is a belt or a chain.

[0042] It is conceivable that the first screw rod and the first driving member 230 can also be arranged on the outer surface of the first fixed rod 210, but being arranged on the outer surface of the first fixed rod 210 can easily cause the first screw rod to be stuck with dust, affecting the user experience and service life of the first screw rod. At the same time, setting the first screw rod on the outer surface of the first fixed rod 210 will also occupy the external space, making it inconvenient to connect other structures. The first screw rod and the first driving member 230 can also be replaced with structures such as telescopic oil cylinders or telescopic air cylinders, but the use of screw rods and driving members can reduce the layout of pipelines, thereby improving the overall weight and aesthetics of the lifting device. The second screw rod 330 and the second driving member 340 are the same.

[0043] In the embodiment of the utility model, a first support seat is provided in the first through hole, and the first screw rod is rotatably provided around its own axis and penetrates the first support seat. Specifically, the purpose of providing the first support seat is to support the first screw rod, thereby reducing the deformation of the first screw rod; the first screw rod is rotatably provided around its own axis and penetrates the first support seat, and the rotation of the first screw rod does not move relative to the first support seat. Figure 3 As shown, a second support seat 312 is disposed in the second through hole 311 , and a second screw rod 330 is rotatably disposed around its own axis and penetrates the second support seat 312 .

[0044] Furthermore, the first support seat is arranged at one end of the first screw rod away from the first movable rod 220, so that the first support seat can also limit the end point of the travel of the first movable rod 220; similarly, the second support seat 312 is arranged at one end of the second screw rod 330 away from the second movable rod 320, so that the second support seat 312 can also limit the end point of the travel of the second movable rod 320.

[0045] In the embodiment of the utility model, the first driving member 230 is installed on one side of the first fixing rod 210 in the horizontal direction. Compared with setting the first driving member 230 on the upper surface of the first fixing rod 210, the first driving member 230 is installed on one side of the first fixing rod 210 in the horizontal direction, which can more conveniently check and maintain the state of the first driving member 230. The second driving member 340 is also installed on one side of the second fixing rod 310 in the horizontal direction.

[0046] In the embodiment of the utility model, the lifting structure 500 includes a roller 510 and a lifting frame 520. The roller 510 is rotatably mounted on the lifting frame 520 around its own axis. The outer peripheral wall of the roller 510 is provided with an inwardly concave annular groove 511. The lifting frame 520 includes a top plate 521. The lifting rope 400 is inserted between the annular groove 511 and the top plate 521. For details, refer to Figure 4As shown, mounting plates 523 are provided at both ends of the top plate 521, and both ends of the roller 510 are respectively mounted on the two mounting plates 523 so as to rotate around their own axes; the top plate 521 is provided with a hanging hole 522 for connecting with a crane. There is a small gap between the bottom of the top plate 521 and the outer surface of the roller 510, so that the sling 400 is restricted by the top plate 521 when passing through the annular groove 511, and the sling 400 is not easy to be separated from the annular groove 511. Since the roller 510 is installed on the lifting frame 520 so as to rotate around its own axis, and the sling 400 is wound in the annular groove 511, compared with directly contacting the hook and the sling 400, the method of indirectly connecting the hook and the sling 400 through the lifting structure 500 makes it easier to slide the hook to the middle position of the sling 400, thereby improving the stability of lifting thick titanium alloy plates; in addition, since the sling 400 is wound in the annular groove 511, when lifting thick titanium alloy plates, the force-bearing area of ​​the sling 400 is larger, thereby reducing the local pressure of the sling 400 and extending the service life of the sling 400.
