Description

Technical Field

[0001] The utility model relates to the technical field of roller processing, in particular to roller hoisting equipment. Background Art

[0002] like Figure 1 and Figure 2 As shown in the figure, the currently widely used roller design cleverly combines the two core components of the roller seat and the roller rod. The roller seat is also provided with a first through hole and a second through hole to meet specific installation and connection requirements. This precise structural design makes the roller have a larger mass after manufacturing. Therefore, after the actual processing process is completed, it is necessary to rely on roller lifting equipment to lift the roller vertically and place it on a transfer cart. The transfer cart then transports it to the designated storage area or the next processing station.

[0003] In the actual operation of roller transportation, due to the inconsistency of the upper and lower diameters of the roller, traditional clamp designs often find it difficult to achieve effective and synchronous clamping of the roller. Most of these clamps are designed to adapt to objects of uniform diameter. Faced with rollers with varying diameters, it is difficult to ensure the stability and safety of the clamping. More importantly, in order to ensure the stability and safety of the roller during the lifting process, the clamps in the prior art generally adopt a horizontal clamping method. However, when the roller needs to be placed on a transfer cart for subsequent transportation, it is required to be placed vertically. This means that after the lifting is completed, the roller needs to be flipped over, which undoubtedly increases the complexity and time cost of transportation. In addition to the clamps, the prior art also often uses slings for lifting and transporting the roller. However, since the outer surface of the roller is usually smooth and irregular in shape, the slings are easy to slip or loosen during the lifting process, which in turn causes safety hazards. Utility Model Content

[0004] The purpose of the utility model is to solve the potential safety problems such as unstable clamping, complicated turning and sling slipping during roller lifting, and to improve the efficiency and safety of roller transportation, and to propose a roller lifting device.

[0058] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 6 As shown; the top limit member 7 includes:

[0059] Two elastic tensioning members 71 are respectively provided on the surfaces of the two side panels 5;

[0060] The movable telescopic plate 72 is provided on the elastic stretching end of the elastic tensioning member 71;

[0061] A limiting sleeve 73 is fixedly mounted on one side surface of the movable telescopic plate 72 close to the roller shaft 2, wherein the limiting sleeve 73 and the roller shaft 2 are adapted to each other in size; and

[0062] When the lever 72 is in the unlocked position, the lever 72 is in the unlocked position, and the spring 73 is in the unlocked position, so that the lever 72 can be unlocked and the spring 73 can be unlocked. The limiting sleeve 73 can be accurately sleeved on the outside of the roller shaft rod 2, thereby limiting the end of the roller shaft rod 2. This design not only improves the stability and safety of the lifting equipment, but also simplifies the operation process and improves work efficiency. The pulling handle 74 is fixedly installed on the other side surface of the movable telescopic plate 72. It serves as a control component for the operator and can easily drive the movable telescopic plate 72 to move. It should also be noted that the movable telescopic plate 72 is similar to the telescopic rod structure in the prior art, and consists of an outer plate and an inner displacement plate. The outer plate is fixed on one of the side plates 5, and the inner displacement plate is fixed on the other side plate 5, and the inner displacement plate can be slidably connected to the inner side of the outer plate, and the limiting sleeve 73 is fixedly installed on the outer plate.

[0063] In a preferred embodiment, the present invention can be further configured as follows: Figure 5 、 Figure 6 As shown; the elastic tensioning member 71 comprises:

[0064] Two fixing blocks 711 are fixedly mounted on the surfaces of the two side panels 5, wherein a first through hole is machined at the center of the fixing block 711;

[0065] A movable rod 712 is disposed inside the first through hole of the fixed block 711 and is vertically displaceable within the first through hole. Two connecting rings are fixedly mounted on the outside of each movable rod 712, wherein the two connecting rings are respectively located on the upper and lower sides of the fixed block 711; and

[0066] When the cam 711 is in the unlock state, the locking cam 713 is locked, and the locking cam 713 is locked. When the movable plate 72 is lifted up, the operator can pull the handle 74 so that the movable plate 72 can be pulled up and down, thereby ensuring that the movable plate 72 is pulled up and down.

[0067] In a preferred embodiment, the present invention can be further configured as follows: Figure 4 、 Figure 6 As shown, vertically distributed slide rails are fixedly mounted on the surfaces of opposite sides of the two side panels 5, and sliders are fixedly mounted on the surface of the movable telescopic plate 72, wherein the sliders are slidably connected to the inner sides of the slide rails. The movable telescopic plate 72 is vertically slidably arranged between the two side panels 5 via the slide rails and the sliders. When the height of the movable telescopic plate 72 needs to be adjusted, the operator can apply an upward force to the movable telescopic plate 72 by pulling the handle 74. At this time, the sliders on the movable telescopic plate 72 will slide on the inner sides of the slide rails, moving in the vertical direction of the slide rails. Due to the coordinated design of the slide rails and the sliders, the vertical sliding of the movable telescopic plate 72 is stable and smooth, without any shaking or jamming.

[0068] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 7 As shown; the tensioning member 8 includes:

[0069] The rectangular frame 81 is fixedly mounted on the surface of one of the side panels 5 and is perpendicular to the side panel 5;

[0070] The screw 82 is provided through the rectangular frame 81, and one end of the screw 82 is rotatably connected to the inner side of the rectangular frame 81;

[0071] A tightening handle 83 is fixedly mounted on one end of the screw rod 82 outside the rectangular frame 81; and

[0072] The threaded sleeve 84 is threadedly connected to the outside of the screw 82 and is located on the inside of the rectangular frame 81, wherein one side surface of the threaded sleeve 84 is fixedly connected to the surface of the other side plate 5, and the rectangular frame 81 is fixedly mounted on the surface of one of the side plates 5 and is perpendicular to the side plates 5. This design enables the rectangular frame 81 to serve as a support and guide structure for the screw 82 and the threaded sleeve 84 to ensure their stable operation. A second through hole is opened on the rectangular frame 81, and a first bearing is provided on the inside of the second through hole. The outer side of the screw 82 is connected to the first bearing. The inner rings of the bearings are fixedly connected to each other. At the same time, a second bearing is also fixedly installed on the inner side of the rectangular frame 81. The end of the screw 82 is rotatably connected to the rectangular frame 81 through the second bearing. This design allows the screw 82 to rotate smoothly on the rectangular frame 81. The screw 82 is set through the rectangular frame 81. One end of the screw 82 is rotatably connected to the rectangular frame 81 through the first bearing and the second bearing, and the other end extends out of the rectangular frame 81 and is fixedly installed with a tightening handle 83. The operator can drive the screw 82 in the rectangular frame by rotating the tightening handle 83. 81 is rotated, the threaded sleeve 84 is threadedly connected to the outside of the screw 82 and is located on the inside of the rectangular frame 81. At the same time, one side surface of the threaded sleeve 84 is fixedly connected to the surface of the other side plate 5. This design makes it possible for the threaded sleeve 84 to move along the axial direction of the screw 82 when the screw 82 rotates. Since the threaded sleeve 84 and the inner surface of the rectangular frame 81 are in contact with each other, when the screw 82 is rotated, the threaded sleeve 84 will not rotate on its own, but will move along the thread direction of the screw 82. During operation, when it is necessary to adjust the two side plates 5, the operator can rotate the tightening handle 83 to drive the screw 82 to rotate on the rectangular frame 81. Since the threaded sleeve 84 is threadedly connected to the screw 82, and one side of the threaded sleeve 84 is fixedly connected to the other side plate 5, when the screw 82 rotates, the threaded sleeve 84 will move along the axial direction of the screw 82, thereby driving the side plate 5 connected thereto to move. In this way, the operator can easily adjust the distance between the two side plates 5, so that they are closer to or farther away from each other, so as to achieve a stable clamping effect on the roller seat 1 and the roller rod 2.

[0073] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 7As shown; a telescopic outer cylinder 10 is fixedly mounted on the surface of one of the side panels 5, and a telescopic inner rod 11 is fixedly mounted on the surface of the other side panel 5, wherein the telescopic inner rod 11 is placed on the inner side of the telescopic outer cylinder 10 at one end close to the telescopic outer cylinder 10 and can slide and displace on the inner side of the telescopic outer cylinder 10. Between the two side panels 5 of the lifting equipment, a matching design of the telescopic outer cylinder 10 and the telescopic inner rod 11 is adopted to achieve distance adjustment. Specifically, a telescopic outer cylinder 10 is fixedly mounted on the surface of one of the side panels 5, and this telescopic outer cylinder 10 has an open inner cavity for accommodating and guiding the sliding of the telescopic inner rod 11, while a telescopic inner rod 11 is fixedly mounted on the surface of the other side panel 5, and one end of the telescopic inner rod 11 is designed to be tightly inserted into the inner side of the telescopic outer cylinder 10 and slide and displace inside it, thereby ensuring the connection strength between the two side panels 5.

[0074] The specific working principle of the roller hoisting device of the utility model is as follows:

[0075] First, move the hoisting equipment to the top of the roller shaft 2 to be hoisted. At this time, the two side plates 5 are located on the left and right sides of the roller shaft seat 1 and remain parallel to each other.

[0076] Next, the limiting sleeve 73 is tightly fitted on the outer side of the roller shaft rod 2 to effectively limit the roller shaft rod 2, and then the tensioning piece 8 is operated to fix the roller shaft seat 1. By rotating the tightening handle 83, the screw 82 is driven to rotate on the rectangular frame 81. Since the threaded sleeve 84 is threadedly connected to the screw 82, and one side of the threaded sleeve 84 is fixedly connected to the other side plate 5, the rotation of the screw 82 will drive the side plate 5 connected to the threaded sleeve 84 to move closer to the other side plate 5. During this process, the distance between the two side plates 5 and the contact between the limiting plate 61 and the limiting seat 63 and the roller shaft seat 1 can be observed, until the first limiting post 62 on the limiting plate 61 is inserted into the first hole 3, the second limiting post 64 on the limiting seat 63 is inserted into the second hole 4, and the two side plates 5 are tightly fitted on the left and right sides of the roller shaft seat 1;

[0077] At this point, the roller seat 1 and the roller shaft rod 2 have been stably restrained in the lifting equipment. Finally, the lifting connecting belt 9 is connected to the lifting machinery, and the roller seat 1 and the roller shaft rod 2 are lifted and moved to a designated position, such as a transfer trolley, by the lifting machinery.

[0078] After hoisting onto the transfer trolley, if the entire hoisting equipment needs to be separated, the operator can again pull the handle 74 to lift the movable telescopic plate 72 upward to separate the limiting sleeve 73 from the end of the roller shaft rod 2. After the separation is completed, the pulling handle 74 can be released, and the movable telescopic plate 72 can be reset under the restoring force of the elastic member 713 to facilitate the next hoisting. Then, the tensioning handle 83 is rotated in the opposite direction to increase the distance between the two side plates 5, thereby releasing the limit on the roller shaft seat 1. Finally, the hoisting connecting belt 9 is disconnected from the hoisting machinery to complete the separation and unloading of the hoisting equipment.

[0079] The entire use process is simple and convenient, and can be adjusted according to the sizes of different roller seats 1 and roller rods 2, ensuring the safety and stability of lifting.
