DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The clamping and lifting device of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 4 As shown, the clamping and lifting device of the embodiment of the utility model may include a base 10 , two support seats 20 , a support arm 30 , an auxiliary mechanism 40 , a clamping assembly 50 , a pull rod 60 and a retractable mechanism 70 .

[0022] The two support seats 20 are arranged side by side on the base 10 , one end of the support arm 30 is pivotally connected to the two support seats 20 via a rotating shaft, and the other end of the support arm 30 is fixedly connected to the clamping assembly 50 via an auxiliary mechanism 40 .

[0023] One end of the pull rod 60 is pivotally connected to the two support seats 20 via a rotating shaft, and the other end of the pull rod 60 is pivotally connected to the clamping assembly 50 . The pull rod 60 is disposed below one side of the support arm 30 .

[0024] One end of the retractable mechanism 70 is pivotally connected to the base 10 , and the other end of the retractable mechanism 70 is pivotally connected to the middle of the support arm 30 .

[0025] It should be noted that the retractable mechanism 70 described in this embodiment may be a cylinder, a hydraulic cylinder or an electric retractable rod.

[0026] It is understandable that after the clamping assembly 50 clamps the pipe in the center, the staff can control the output end of the telescopic mechanism 70 to extend, and the pull rod 60 at this time will adjust the angle of the clamping assembly 50 so that the clamping assembly 50 is always in a vertical state. After the output end of the telescopic mechanism 70 is extended to the right position (that is, after the height of the clamping assembly 50 is raised to the right position), the staff can control the clamping assembly 50 to release the pipe, and the pipe is transported to the height position to be processed (the position can be on the workbench of the cutting machine), thereby completing the automatic feeding of the pipe. It effectively reduces the time and labor intensity of manual operation, improves the production efficiency of pipes, and also reduces labor costs and the possibility of accidents.

[0027] In order to clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 2 and Figure 3 As shown, the auxiliary mechanism 40 may include a U-shaped frame 41 , two support plates 42 , a support shaft 43 and a support roller 44 .

[0028] Among them, the U-shaped frame 41 is fixedly set on the other end wall of the support arm 30, and the two support plates 42 are respectively set on both sides of the U-shaped frame 41, and one end of the two support plates 42 is pivotally connected to the U-shaped frame 41 through a support shaft 43, and the other end of the two support plates 42 is connected to the clamping assembly 50.

[0029] The support roller 44 is rotatably disposed between the two support plates 42 .

[0030] It can be understood that, by providing the support roller 44 , it can play a role in limiting and supporting the pipe when the clamping assembly 50 clamps the pipe to take out the material.

[0031] Further, in one embodiment of the present invention, Figure 4 As shown, the clamping assembly 50 may include a mounting box 51 , two slide rails 52 , two clamping mechanisms 53 and a driving mechanism 54 .

[0032] The installation box 51 is fixedly connected to the other ends of the two support plates 42 , and a through slot 501 is provided on the top wall of the installation box 51 . The top wall of the installation box 51 is lower than the height of the support rollers 44 .

[0033] The two slide rails 52 are fixedly arranged side by side on the inner wall of the installation box 51 , and the two clamping mechanisms 53 are slidably arranged on the corresponding slide rails 52 , and the top ends of the two clamping mechanisms 53 pass through the through slot 501 and extend to the top of the installation box 51 .

[0034] The driving mechanism 54 is disposed in the installation box 51 , and the driving mechanism 54 is connected to the two clamping mechanisms 53 respectively.

[0035] In order to clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 4 As shown, the clamping mechanism 53 may include two sliders 531 , a rack 532 , a clamping arm 533 and a clamping roller 534 .

[0036] The two sliders 531 are arranged side by side and slidably on the corresponding slide rails 52 , and the racks 532 are fixedly arranged on the two sliders 531 .

[0037] The clamping arm 533 is vertically fixedly arranged at one end of the rack 532, and the top end of the clamping arm 533 passes through the through slot 501 and extends to the top of the installation box 51, wherein the clamping arm 533 located above the installation box 51 is provided with a placement slot 502. The clamping roller 534 is rotatably arranged in the placement slot 502. It should be noted that the clamping roller 534 described in this embodiment can be a rubber roller. It is understandable that by setting the clamping roller 534 as a rubber roller, it is possible to avoid the clamping roller 534 from causing clamping damage to the pipe when clamping the pipe.

[0038] In order to further explain the above embodiment, in one embodiment of the present utility model, as Figure 4 As shown, the driving mechanism 54 may include a gear 541 and a retractable component 542 , wherein the gear 541 is rotatably disposed on the inner wall of the installation box 51 , and the gear 541 is respectively meshed with the racks 532 in the two clamping mechanisms 53 .

[0039] The retractable component 542 is disposed in the installation box 51 , and an output end of the retractable component 542 is fixedly connected to the other end of one of the racks 532 .

[0040] It should be noted that the retractable component 542 described in this embodiment may be a cylinder, a hydraulic cylinder or an electric retractable rod.

[0041] Specifically, when it is necessary to lift the pipe to the position to be processed, the staff can transport the pipe to the installation box 51 located between the two clamping rollers 534 by controlling the feeding machine (for example, a belt conveyor) or manually pushing the material, and the support roller 44 can limit the pipe located on the installation box 51.

[0042] Then, the staff can control the output end of the retractable component 542 to extend, and push the corresponding rack 532 to slide on the slide rail 52 through the slider 531. The sliding rack 532 drives the gear 541 to rotate, and the rotating gear 541 drives another rack 532 to slide towards the rack 532 (i.e., drives the two racks 532 to slide towards each other). The two racks 532 sliding towards each other drive the clamping rollers 534 to move towards each other through the corresponding clamping arms 533, and then the pipe is clamped and fixed in the center by the two clamping rollers 534 moving towards each other.

[0043] At the same time, the staff controls the output end of the retractable mechanism 70 to extend and pushes the support arm 30 to rotate upward, thereby driving the clamping assembly 50 to rotate upward to lift the pipe. During the upward rotation of the support arm 30, the pull rod 60 also rotates accordingly. At this time, the pull rod 60 will adjust the angle of the clamping assembly 50 so that the clamping assembly 50 is always in a vertical state.

[0044] When the pipe is lifted to the position to be processed, the staff can control the output end of the retractable component 542 to retract (reset), and the two support rollers 44 move back (towards opposite directions), thereby releasing the clamped pipe and achieving lifting and loading of the pipe.

[0045] In summary, the clamping and lifting device of the embodiment of the utility model can automatically center, clamp, lift and feed the pipe, effectively reducing the time and labor intensity of manual operation, improving the production efficiency of the pipe, and also reducing labor costs and the possibility of accidents.
