Description

Technical Field

[0001] The present application relates to the technical field of industrial lifting devices, and in particular to a steel lifting device. Background Art

[0002] At present, a large number of long steel strips need to be cut and processed in steel mills, heavy machinery factories, etc. Usually, the staff are required to place the steel to be cut and processed on a fixed frame first. When the cutting machine is actually used, the feeding position height of the steel will be different due to different cutting requirements and the assembly of different cutting blades. During the actual cutting operation, the staff will select the feeding position of the corresponding height according to the needs and fix it to the end of the steel to be cut.

[0003] Since the steel is long and heavy, workers need to adjust the height of the steel to adapt to feeding positions at different heights, which is time-consuming and labor-intensive, and there is room for improvement. Utility Model Content

When it moves to a suitable height, the two fixing nuts are screwed in the direction of approaching each other until the opposite sides of the two fixing nuts are respectively abutted against the two sides of the upper plate, thereby completing the height adjustment of the screw rod and reducing the possibility of the screw rod loosening due to external forces such as vibration.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0031] The embodiment of the present application discloses a steel lifting device.

[0032] Embodiment 1:

[0033] Reference Figure 1 A steel lifting device comprises a guide rail 1 with an L-shaped cross section. Two guide rails 1 are arranged on the ground facing each other. A support frame 2 is slidably arranged on the guide rail 1. The support frame 2 comprises a rectangular upper plate 21 and a lower plate 22. A support rod 23 is welded between the upper plate 21 and the lower plate 22. Four support rods 23 are arranged. Guide wheel shafts 24 are welded on opposite sides of the lower plate 22. Pulleys 25 are rotatably connected at both ends of any guide wheel shaft 24. The pulleys 25 form a guided sliding fit with the guide rail 1, so that the support frame 2 can easily slide between different positions of the guide rail 1, which is convenient for adapting to the length changes of the steel during the cutting process. The arrangement of the pulley 25 significantly reduces the time and manpower required for carrying the support frame 2, thereby greatly improving the work efficiency.

[0034] Reference Figure 1 An adjusting mechanism 3, a screw rod 4 and an opening groove 5 are provided on the upper plate 21. The adjusting mechanism 3 includes a fixing nut 31. The screw rod 4 passes through the upper plate 21. Two fixing nuts 31 are provided and are threadedly connected to the screw rod 4. The two fixing nuts 31 are respectively arranged on two opposite sides of the upper plate 21, and the opposite sides of the two fixing nuts 31 respectively form abutment with the upper plate 21.

[0035] Reference Figure 1 In actual use, the two fixing nuts 31 are screwed in opposite directions. At this time, the screw rod 4 can be moved in the vertical direction to adjust the height of the screw rod 4. When it moves to a suitable height, the two fixing nuts 31 are screwed in the direction of approaching each other until the opposite sides of the two fixing nuts 31 are respectively abutted against the two sides of the upper plate 21, thereby completing the height adjustment of the screw rod 4 and reducing the possibility of the screw rod 4 loosening due to external forces such as vibration.

[0036] Reference Figure 1A holding frame 41 for supporting steel is provided at one end of the screw rod 4 away from the opening groove 5 . The holding frame 41 is arranged in a V shape and is welded to the screw rod 4 .

[0037] The implementation principle of the embodiment of the present application is as follows: during actual operation, the staff first places the long strip of steel on the holding rack 41, and then manually adjusts the height of the screw rod 4 by loosening the fixing nut 31 on the screw rod 4, thereby adjusting the height of the steel on the holding rack 41. The staff can adjust the steel to the required height as needed, which is convenient for the cutting machine to cut the steel. At the same time, the setting of the pulley 25 is used to facilitate the adaptation to the length change of the steel during the cutting process, which significantly reduces the time and manpower required for carrying the support frame 2 and greatly improves work efficiency.

[0038] Embodiment 2:

[0039] The difference between the second embodiment and the first embodiment is that:

[0040] Reference Figure 2 The adjusting mechanism 3 includes a worm wheel 32, a worm 33 matched with the worm wheel 32, and a bearing sleeve 34. The worm wheel 32 is threadedly connected to the screw 4, and the worm wheel 32 is rotatably connected to the bearing sleeve 34. The bearing sleeve 34 is threadedly connected to the upper plate 21 through bolts. Since the worm gear transmission has a self-locking property, that is, when the worm wheel 32 and the worm 33 stop moving, the screw 4 can maintain its original position and will not be reversed due to factors such as vibration.

[0041] Reference Figure 2 , one end of the screw rod 4 away from the worm gear 32 is detachably connected with a connecting piece 35. In the present embodiment, the connecting piece 35 is threadedly connected to the screw rod, and the receiving rack 41 is welded to the connecting piece 35. The receiving rack 41 can be set to a V-shape, a U-shape and a hemispherical shape. Since the receiving rack 41 is threadedly connected to the screw rod 4, it is convenient to replace or adjust the receiving rack 41 to adapt to steels of different specifications. At the same time, after the connecting piece 35 and the receiving rack 41 are raised and lowered to a limited position with the screw rod 4, the staff can slightly adjust the placement angle of the receiving rack 41 by screwing the connecting piece 35, so that the placement angle of the receiving rack 41 can be adapted to the placement of the steel on the cutting machine, and then the receiving rack 41 can firmly support the steel.

[0042] Reference Figure 3, the holding rack 41 is symmetrically provided with balls 411 for assisting the transportation of steel. Any ball 411 forms a rotational connection with the holding rack 41, which helps to reduce the friction between the steel and the holding rack 41, making the steel smoother during the transportation process; when it is necessary to make a small displacement adjustment to the steel, the staff only needs to use the setting of the ball 411 to make a small displacement of the steel. When it is necessary to make a large displacement adjustment to the steel, the staff needs to use their hands to support the steel and the holding rack 41 at the same time to ensure that the steel and the pulley 25 on the support frame 2 move synchronously.

[0043] Reference Figure 3 The worm 33 is provided with a driving member 36 for driving the worm 33 to rotate. In the present embodiment, the driving member 36 is configured as a hand wheel 361, the hand wheel 361 is welded to one end of the worm 33, and the hand wheel 361 is provided with a hand lever for the operator to operate conveniently. Directly rotating the hand lever makes it easier and more stable for the operator to rotate the worm 33.

[0044] The implementation principle of the embodiment of the present application is as follows: during actual operation, the staff first places the long strip of steel on the corresponding shape of the storage rack 41, and then drives the worm 33 to rotate by rotating the hand wheel 361 through the hand lever, so that the rotation of the worm 33 drives the worm wheel 32 to rotate, and then the lead screw 4 on the worm wheel 32 can be smoothly lifted and lowered in the vertical direction, thereby realizing the adjustment of the height of the steel on the storage rack 41. The staff can adjust the steel to the required height according to the needs, which is convenient for the cutting machine to cut the steel. At the same time, the setting of the pulley 25 is used to facilitate the adaptation to the length change of the steel during the cutting process, which significantly reduces the time and manpower required for carrying the support frame 2 and greatly improves the work efficiency.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
