Description

Technical Field

[0001] The utility model relates to the technical field of color steel plate lifting, in particular to a color steel plate lifting device. Background Art

[0002] Color coated steel plate refers to color coated steel plate. Color coated steel plate is a steel plate with an organic coating. It has the advantages of good corrosion resistance, bright colors, beautiful appearance, easy processing and forming, and the original strength of the steel plate at a low cost.

[0003] In the prior art, when lifting the color steel plate, two U-shaped frames are usually used to clamp and fix the two sides of the color steel plate. The two frames are mainly clamped by a pulling mechanism such as a screw nut, and finally the two frames are pulled and lifted by a lifting rope.

[0004] However, the method of fastening the color steel plate by the frame through the tension structure such as the lead screw, on the one hand, relies on manual or mechanical adjustment of the fastening force. The uniformity and stability of the fastening force are easily affected by human factors or equipment wear, and there is a problem of unreliable fastening. The color steel plate is prone to sliding on the frame, especially when the two ends of the color steel plate are unbalanced, there is a safety hazard of the color steel plate falling off, which increases the safety risk when lifting the color steel plate; on the other hand, when clamping the color steel plate, frequent manual or mechanical adjustments are required, the operation is cumbersome, and the construction efficiency is low.

DETAILED DESCRIPTION

[0035] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0036] This embodiment aims to provide a color steel plate lifting device, which is mainly used for lifting and transporting color steel plates. It aims to solve the problems of unreliable fastening and complicated operation of the method of fastening the color steel plates by relying on a pulling structure such as a lead screw.

[0037] A color steel plate lifting device, such as Figure 1 , including a base 1, a clamping frame and a clamping assembly. The clamping frame is vertically fixed to the left and right ends of the base 1, such as Figure 2 The clamping frame includes two sets of clamping arms spaced apart from each other, with a clamping space formed between the two sets of clamping arms 2. Each set of clamping arms in the clamping frame is provided with a clamping assembly facing the clamping space. In other embodiments, only one set of clamping arms in the clamping frame may be provided with a clamping assembly.

[0038] like Figure 4 The clamping assembly includes a clamping base 3, a clamping cam 4, a return spring 5, and a suspension rope 6. In this embodiment, the clamping base 3 is U-shaped, extending vertically and opening toward the clamping space. A rotating shaft 7 is fixedly connected to the clamping base 3 in the horizontal direction, and the clamping cam 4 is rotatably mounted on the rotating shaft 7.

[0039] The clamping seat 3 is arranged on the clamping arm, specifically, as Figure 3 The left and right side walls of the clamping arm 2 are both provided with adjustment waist holes 203 extending in the vertical direction, and the adjustment waist holes 203 are provided on the side walls of the mounting groove 201; the clamping seat 3 is provided with a limiting through hole adapted to the adjustment waist hole 203, and the rotating shaft 7 passes through the adjustment waist hole 203 and the limiting through hole in sequence. Both ends of the rotating shaft 7 are threadedly connected with fixing nuts 8, and the clamping seat 3 and the clamping arm 2 are detachably connected through the fixing nuts 8, so that the clamping assembly can be adjusted up and down to adapt to the sizes of different color steel plates.

[0040] like Figure 4The lower end of the lifting rope 6 is set on the near rest point of the clamping cam 4, and the upper end of the lifting rope 6 passes through the clamping arm 2 upward and extends to the top of the clamping arm 2; when the lifting rope 6 is stretched upward, the far rest point of the clamping cam 4 rotates toward the clamping space to clamp the color steel plate in the clamping space; a reset spring 5 is fixedly connected between the wheel surface of the clamping cam 4 and the bottom of the clamping seat 3. When the clamping cam 4 rotates, the reset spring 5 will be stretched to bring elastic potential energy. After the lifting is completed, the elastic potential energy of the reset spring 5 will reset the clamping cam 4 to its initial angle, so that it can be used to lift the color steel plate next time. In this embodiment, the far rest point of the clamping cam 4 is the point on the cam wheel surface contour that is farthest from the cam rotation center, and the near rest point of the clamping cam 4 is the point on the cam wheel surface contour that is closest to the cam rotation center and farthest from the far rest point.

[0041] In this embodiment, a rope hole 202 is provided on the upper end surface of the clamping arm 2, which passes through the upper and lower parts. The upper end of the suspension rope 6 passes through the rope hole 202 upward from between the clamping cam 4 and the clamping seat 3 and extends to the top of the clamping arm 2, ensuring that when the suspension rope 6 is stretched upward, the clamping cam 4 rotates counterclockwise, thereby causing the far rest point of the clamping cam 4 to rotate toward the clamping space.

[0042] Further, such as Figure 3 The clamping arm 2 is provided with a mounting groove 201 which is open toward the clamping space, and the clamping seat 3 is arranged in the mounting groove 201. When and only when the suspension rope 6 is stretched upward, the far rest point of the clamping cam 4 leaves the mounting groove 201, so that in a natural state, the clamping cam 4 is hidden in the mounting groove 201, which is convenient for carrying the color steel plate in the clamping space.

[0043] Furthermore, a limit cavity 401 is provided on the near-rest point of the clamping cam 4, and a limit cover 402 is fixed on the near-rest point of the clamping cam 4 to cover the limit cavity 401; a through limit hole 403 is provided on the limit cover 402, and the lower end of the lifting rope 6 passes through the limit hole 403 and is limitedly set in the limit cavity 401.

[0044] In this embodiment, the sling rope 6 is a steel wire rope. The lower end of the sling rope 6 is threadedly connected to a limit nut 404, which is then positioned within the limit cavity 401, thereby connecting the lower end of the sling rope 6 to the near-rest point of the clamping cam 4. The specific connection method is as follows: first, the lower end of the sling rope 6 is passed through the limit hole 403 of the limit cover 402. Then, the limit nut 404 is threadedly connected to the lower end of the sling rope 6 and placed within the limit cavity 401. Finally, the limit cover 402 is screwed onto the limit cavity 401. In other embodiments, if the sling rope 6 is a flexible rope such as a linen rope, the lower end of the sling rope 6 can be connected to the near-rest point of the clamping cam 4 by tying a knot and positioning the knot point within the limit cavity 401.

[0045] Furthermore, a clamping portion 404 is fixed to the far rest point of the clamping cam 4 , and the outer surface of the clamping portion 404 has an elastic cushion layer, which can avoid scratching or crushing the color steel plate when clamping the color steel plate.

[0046] Furthermore, the base 1 includes an adjustment seat 101, a slider 102 and a bidirectional screw 103; the adjustment seat 101 is located on the left and right sides of the base 1, and a bidirectional screw 103 is arranged in the adjustment seat 101 for rotating back and forth; the two groups of adjustment seats 101 are provided with adjustment slots 105 extending in the front and back directions, and two groups of sliders 102 are slidingly arranged in the two groups of adjustment slots 105, and the two groups of sliders 102 are respectively threadedly connected to the thread sections of the bidirectional screw with opposite rotation directions; the clamping arm 2 is fixed on the slider 102 accordingly, and when the bidirectional screw rotates, the two groups of adjustment seats 101 can move closer or farther away, so that the two groups of clamping arms 2 move closer or farther away from each other, realizing the front and rear spacing adjustment of the clamping space to adapt to color steel plates of different sizes.

[0047] Furthermore, a telescopic frame 104 extending in the left and right directions is fixedly connected between the two groups of adjustment seats 101 of the base 1 to adjust the left and right widths of the clamping space to adapt to color steel plates of different sizes.
