Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a lifting tool, particularly a sheet metal lifting tool. Background Technology

[0002] In the production of wooden planks, due to the numerous processing steps, lifting equipment is often used with plank lifting devices to move the planks from one stage to the next. Existing plank lifting devices typically use ropes to bind the planks. While suitable for planks of different sizes, this method is not always reliable in securing the planks. Furthermore, ordinary ropes are prone to breakage, have a short lifespan, and are unsafe; while steel cables can easily damage the planks. Therefore, the current method of binding planks with ropes is insufficient to ensure both safety and reliability while preventing damage to the planks.

[0003] An improved wood board lifting device disclosed in Chinese patent literature (application number: 201721136293.1) includes a lifting frame, hooks, sleeves, positioning pins, and a support plate. The lifting frame consists of horizontal and vertical bars. The hooks are connected to the top of the vertical bars of the lifting frame via a swivel joint. The sleeves are located on the vertical bars of the lifting frame, and the sleeves are fitted with the vertical bars of the lifting frame using an interference fit. The positioning pins are connected to the middle of the side circumference of the sleeves and are L-shaped bends. The support plate is connected to the bottom of the lifting frame. When lifting wood boards, if furniture boards to be sprayed need to be placed, the two sleeves are slid upward relative to the lifting frame. Then, the furniture boards to be sprayed are vertically and accurately placed on the support plate. Then, the two sleeves are slid downward along the lifting frame, so that the positioning pins on the sleeves clamp the furniture boards to be sprayed, thereby achieving stable positioning and lifting of the furniture boards. Therefore, lifting wood boards is inconvenient, and the two positioning pins can easily scratch the surface of the boards. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a sheet metal lifting tool that is simple in structure, easy to operate, and less likely to scratch the surface of the workpiece.

[0005] The objective of this utility model can be achieved through the following technical solution: A sheet metal lifting device includes a connecting sleeve, wherein the connecting sleeve has a transverse through-hole in the middle, and a lifting lug is fixedly connected to the upper side of the connecting sleeve. The connecting sleeve is characterized by having a swing frame, the upper end of which passes through the connecting sleeve, and the swing frame is capable of swinging relative to the connecting sleeve around the axis of the connecting hole. The side of the swing frame is provided for the side of the sheet metal to abut against, and both sides of the lower end of the swing frame are provided with slots for the lower end of the sheet metal to be inserted into, the slots having upward openings. A pressure rod is fixedly connected to the side of the connecting sleeve, and the pressure rod can press against the other side of the workpiece and press the sheet metal against the swing frame.

[0006] When hoisting sheet metal, place the sheet metal against the side of the swing frame and insert the lower end of the sheet metal into the slot of the swing frame. Press the pressure rod against the workpiece and lift the connecting sleeve through the lifting lug. Under the action of the sheet metal's gravity, the swing frame tends to move towards the pressure rod, so that the pressure rod presses tightly against the sheet metal on the swing frame. This allows the sheet metal to be stably positioned on the swing frame during hoisting, which has the advantages of stable and reliable hoisting, simple structure, convenient operation, and less likely to scratch the surface of the workpiece.

[0007] In the aforementioned sheet metal lifting device, the swing frame includes a connecting rod that passes laterally through a connecting hole. Both ends of the connecting rod extend out of a connecting sleeve. Two swing arms are fixedly connected to both ends of the connecting rod. The two swing arms are symmetrically arranged on both sides of the connecting rod. A support body is fixedly connected to the lower end of each swing arm. The inner end of the support body is vertically positioned at the lower end of the swing arm, and a limiting protrusion is vertically provided at the outer end of the support body. The support body, the limiting protrusion, and the lower end of the corresponding swing arm form the aforementioned groove. This design provides the swing frame structure with advantages such as reliability, stability, and ease of manufacturing.

[0008] In the aforementioned sheet metal lifting device, the connecting rod and the swing arm are fixedly connected by welding. This welding connection provides the advantages of a strong connection and a compact structure.

[0009] In the aforementioned sheet metal lifting device, the connecting rod and the swing arm are fixedly connected by a threaded structure. This threaded connection provides the advantages of convenient assembly and disassembly, and a secure connection.

[0010] In the aforementioned sheet metal lifting device, a connecting column is vertically fixed to the side wall of the connecting sleeve, and the upper end of the pressure rod is vertically fixed to the outer end of the connecting column. The pressure rod is fixed to the connecting sleeve through the connecting column, so that the pressure rod and the swing frame form an angle, which improves the pressure effect of the pressure rod on the sheet metal and prevents the sheet metal from falling off.

[0011] In the aforementioned sheet metal lifting device, a support rod is fixedly connected between the two swing arms, with both ends of the support rod respectively fixed to the swing arms. The support rod is arranged parallel to the connecting rod. By setting the aforementioned support rod, the strength of the swing frame is increased, and its service life is improved.

[0012] In the above-mentioned sheet metal lifting device, the included angle between the two swing arms and the connecting rod is 0-53°.

[0013] In the aforementioned sheet metal lifting device, two limiting posts are vertically fixed to the connecting rod. These two limiting posts are located on both sides of the connecting sleeve and can abut against the end faces of the connecting sleeve. The limiting posts are fixed to the connecting rod via a threaded structure, and the abutment against the end faces of the connecting sleeve prevents axial movement of the connecting sleeve relative to the connecting rod, thus improving operational reliability.

[0014] In the aforementioned sheet metal lifting device, the connecting sleeve is elongated and cylindrical with a connecting hole in its center. The elongated cylindrical shape of the connecting sleeve offers advantages such as simple structure and ease of manufacturing.

[0015] In the aforementioned sheet metal lifting device, the connecting sleeve is ball-shaped and the connecting hole and connecting sleeve are coaxially arranged. The ball-shaped connecting sleeve has the advantage of a long service life.

[0016] In the aforementioned sheet metal lifting device, a buffer sleeve is fitted onto the lower end of the pressure rod. By providing the buffer sleeve, the pressure rod is less likely to scratch the surface of the sheet metal.

[0017] Compared with existing technologies, this sheet metal lifting tool has the following advantages: 1. By lifting the connecting sleeve with the lifting lugs, the swing frame tends to move towards the pressure rod under the weight of the sheet metal, so that the pressure rod presses the sheet metal on the swing frame tightly, and the sheet metal can be stably positioned on the swing frame. It has the advantages of convenient hoisting, simple structure, convenient operation and not easy to scratch the surface of the workpiece. 2. The lower ends of the two swing arms of the swing frame are fixedly connected to the support body. The inner end of the support body is vertically set at the lower end of the swing arm, and the outer end of the support body is vertically provided with a limiting protrusion. The support body, the limiting protrusion and the lower end of the corresponding swing arm form a groove, which makes the swing frame structure reliable and stable and easy to manufacture. 3. The pressure bar is fixed to the connecting sleeve through the connecting column, so that the pressure bar and the swing frame form an angle, which improves the pressure effect of the pressure bar on the plate and prevents the plate from falling off; 4. The limiting posts are fixed to the connecting rod by a threaded structure. The two limiting posts abut against the two end faces of the connecting sleeve to prevent the connecting sleeve from moving axially relative to the connecting rod, thus improving the reliability of operation.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1 to 4 As shown, a sheet metal lifting device includes a long cylindrical connecting sleeve 1. The connecting sleeve 1 has a transversely penetrating connecting hole 1a in the middle. A lifting lug 1b is fixedly connected to the upper side of the connecting sleeve 1. The connecting sleeve 1 is provided with a swing frame 2. The upper end of the swing frame 2 passes through the connecting sleeve 1, and the swing frame 2 can swing relative to the connecting sleeve 1 around the axis of the connecting hole 1a. The side of the swing frame 2 is provided for the side of the sheet metal 6 to abut against. Both sides of the lower end of the swing frame 2 are provided with slots 2a for the lower end of the sheet metal 6 to be inserted. The opening of the slots 2a is set facing upward. A connecting column 1c is vertically fixed to the side wall of the connecting sleeve 1. A pressure rod 3 is vertically fixed to the outer end of the connecting column 1c. The pressure rod 3 is located on the side of the connecting sleeve 1. The pressure rod 3 can press against the other side of the workpiece and press the sheet metal 6 against the swing frame 2.

[0026] The swing frame 2 includes a connecting rod 2b that passes laterally through the connecting hole 1a. Both ends of the connecting rod 2b extend out of the connecting sleeve 1. Two swing arms 2c are fixedly connected to both ends of the connecting rod 2b. The two swing arms 2c are symmetrically arranged on both sides of the connecting rod 2b. A support body 2d is fixedly connected to the lower end of each swing arm 2c. The inner end of the support body 2d is vertically positioned at the lower end of the swing arm 2c, and a limiting protrusion 2e is vertically provided at the outer end of the support body 2d. The support body 2d, the limiting protrusion 2e, and the lower end of the corresponding swing arm 2c form the aforementioned groove 2a. The connecting rod 2b and the swing arm 2c are fixedly connected by welding, giving the swing frame 2 a reliable and stable structure and the advantage of easy manufacturing. Alternatively, the connecting rod 2b and the swing arm 2c are fixedly connected by a threaded structure.

[0027] A support rod 2f is fixedly connected between the two swing arms 2c, with both ends of the support rod 2f fixedly connected to the swing arms 2c respectively. The support rod 2f is arranged parallel to the connecting rod 2b.

[0028] When hoisting sheet metal 6, sheet metal 6 is placed against the side of the swing frame 2, and the lower end of sheet metal 6 is inserted into the slot 2a of the swing frame 2. The pressure rod 3 is pressed against the workpiece. The connecting sleeve 1 is lifted by the lifting lug 1b. Under the weight of sheet metal 6, the swing frame 2 tends to move towards the pressure rod 3, so that the pressure rod 3 presses tightly against sheet metal 6 on the swing frame 2. This ensures that sheet metal 6 is stably positioned on the swing frame 2 during hoisting. It has the advantages of simple structure, convenient operation, and less risk of scratching the surface of the workpiece. The pressure rod 3 is fixed to the connecting sleeve 1 by the connecting column 1c, so that the pressure rod 3 and the swing frame 2 form an angle, which improves the pressing effect of the pressure rod 3 on sheet metal 6 and prevents sheet metal 6 from falling off.

[0029] As a preferred option, such as Figure 5 As shown, two limiting posts 4 are vertically fixed to the connecting rod 2b. The two limiting posts 4 are located on both sides of the connecting sleeve 1 and can abut against the two end faces of the connecting sleeve 1 respectively, preventing the connecting sleeve 1 from moving axially relative to the connecting rod 2b and improving the reliability of operation. The lower end of the pressure rod 3 is fitted with a buffer sleeve 5 to prevent the pressure rod 3 from scratching the surface of the sheet metal 6.

[0030] Preferably, the connecting sleeve 1 is ball-shaped and the connecting hole 1a is coaxially arranged with the connecting sleeve 1.
