It mainly consists of functional components such as rails, suspension devices, traveling trolleys, and electric hoists. It uses a motor to drive a mechanical system, which moves wire ropes or chains to achieve functions such as lifting, moving, and lowering items.

[0003] A suspended crane connects to an object via a hook, which is then connected to the drum of an electric hoist via a wire rope. When the drum rotates, the wire rope drives the hook to move up and down, thus lifting the object. The wire rope is a crucial connecting component in lifting operations. During the lifting process, the object may sway due to environmental factors such as wind and external forces. This swaying can not only cause collisions between objects but also reduce the stability of the lifting operation, increasing the risk of accidents and thus lowering the safety of the equipment during use.

[0020] like Figure 1-4 As shown, this is the first embodiment of the present invention, which provides an electric suspension crane that facilitates stable operation, comprising:

[0021] The lifting unit 1 includes a support beam 101, an electric hoist body 102 movably connected to the surface of the support beam 101, and a hook body 103 connected to the bottom of the electric hoist body 102 by a wire rope.

[0022] The positioning unit 2 includes a mounting plate 201 fixedly connected to the back of the electric hoist body 102, a mounting block 202 detachably connected to the inner cavity of the mounting plate 201, a telescopic component 203 fixedly connected to the inner cavity of the mounting block 202, a connecting plate 204 disposed at the bottom of the telescopic component 203, a fixing component 205 disposed on the front of the connecting plate 204, and a mounting component 206 disposed in the inner cavity of the mounting plate 201.

[0023] like Figure 1-4As shown, the support beam 101 serves as the skeleton of the entire crane, bearing the weight of the electric hoist body 102 and the hook body 103, as well as the weight of the object being lifted, ensuring the structural stability of the crane. The electric hoist body 102 is the power source of the crane, driven by an electric motor to achieve the lifting and lowering of heavy objects, featuring simple operation and high lifting efficiency. The hook body 103 is connected to the electric hoist body 102 via a wire rope, used for directly suspending and lifting objects. Its flexible design can adapt to heavy objects of different shapes and sizes. The mounting plate 201 is... Other components provide a stable installation platform. The mounting block 202 is detachably connected to the mounting plate 201. The positioning unit 2 can be added or removed according to the usage scenario. The telescopic component 203 is composed of multiple socketed hollow columns, which can realize the telescopic adjustment of the crane in the vertical direction to adapt to the positioning requirements of different heights. The fixing component 205 is used to connect with the wire rope of the lifting equipment and, together with the telescopic component 203 and the connecting plate 204, positions the wire rope to prevent the items from shaking during the hoisting process, thereby improving the safety and stability of the hoisting process. Example

[0024] Reference Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] In this embodiment, the telescopic component 203 is composed of multiple sleeved hollow columns, and adjacent hollow columns are positioned by positioning grooves and positioning blocks. The surface of the outermost hollow column is fixedly connected to the inner cavity of the mounting block 202, and the lower end of the innermost hollow column is fixedly connected to the top of the connecting plate 204.

[0026] The fixing assembly 205 includes a fixing ring 2051 fixedly connected to the front of the connecting plate 204, a movable ring 2052 disposed on the front of the fixing ring 2051, a threaded rod 2053 threadedly connected to the right side of the movable ring 2052, the rear end of the threaded rod 2053 being movably connected to the front of the fixing ring 2051 via a bearing, and a positioning rod 2054 fixedly connected to the upper and lower ends of the back of the movable ring 2052, the rear end of the positioning rod 2054 passing through the fixing ring 2051 and slidingly connected to the inner cavity of the fixing ring 2051.

[0027] like Figure 2 As shown, the design of the telescopic component 203 improves the operating range and flexibility of the crane. The fixed component 205, through the combination of the fixed ring 2051, the movable ring 2052, the threaded rod 2053 and the positioning rod 2054, can limit the wire rope and prevent it from swaying during hoisting. Example

[0028] Reference Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0029] In this embodiment, the mounting component 206 includes a mounting groove 2061 formed on the front of the mounting block 202 and an insertion plate 2062 fixedly connected to the inner cavity of the mounting plate 201. The rear end of the insertion plate 2062 extends into the inner cavity of the mounting groove 2061 and is detachably connected to the inner cavity of the mounting groove 2061.

[0030] The mounting assembly 206 also includes receiving grooves 2063 on both sides of the insertion plate 2062, locking blocks 2064 slidably connected to the inner cavity of the receiving grooves 2063, stainless steel compression springs 2065 fixedly connected to the side of the two locking blocks 2064 that are close to each other, one end of the stainless steel compression spring 2065 away from the locking block 2064 being fixedly connected to the inner wall of the receiving groove 2063, and locking slots 2066 on both sides of the mounting block 202, one side of the stainless steel compression spring 2065 extending into the inner cavity of the locking slot 2066 and engaging with its inner cavity.

[0031] like Figure 3 As shown, the cooperation between the mounting groove 2061 and the insertion plate 2062 enables a detachable connection between the mounting block 202 and the mounting plate 201, facilitating installation and disassembly. The combination of the receiving groove 2063, the locking block 2064, and the stainless steel compression spring 2065 constitutes a fastening mechanism. The spring force locks the locking block 2064 into the locking groove 2066, ensuring a tight connection between the mounting block 202 and the mounting plate 201.

[0032] In use, the hook body 103 is connected to the object. The hook body 103 is connected to the drum of the electric hoist body 102 via a wire rope. When the drum rotates, the wire rope drives the hook body 103 to move up and down, thereby lifting the object. When there are physical influences such as wind in the environment, the positioning unit 2 can be used to position the wire rope. First, the mounting block 202 is installed. The mounting block 202 is moved to the rear end of the mounting plate 201 and gradually pushed forward so that... As the mounting slot 2061 is gradually inserted, the locking block 2064, due to its beveled side, is compressed by the inner wall of the mounting slot 2061 during insertion, gradually moving into the inner cavity of the receiving slot 2063. During this movement, the locking block 2064 compresses the stainless steel compression spring 2065, causing it to deform, until it reaches the same straight line as the locking slot 2066. At this point, the compression effect on the locking block 2064 disappears, and the stainless steel compression spring 2065 returns to its original position. Under the action of elastic force, the locking block 2064 can be inserted into the inner cavity of the locking slot 2066 and engage with it, thus positioning the mounting block 202. Next, the wire rope is moved to a position between the fixed ring 2051 and the movable ring 2052. Then, the threaded rod 2053 is rotated. As the threaded rod 2053 rotates, it adjusts the position of the movable ring 2052, causing it to move backward. At this time, the distance between the fixed ring 2051 and the movable ring 2052 gradually decreases, and the fixed ring 2051 and the movable ring 2052... The surface of the wire rope is clamped together, and then the hook body 103 is fixed to the object. During the hoisting process, the multiple hollow columns of the telescopic component 203 and the connecting plate 204 work together to support and position the wire rope to prevent it from shaking. The multiple movable sleeves of the telescopic component 203 can extend and retract, so they can extend and retract with the lifting and lowering of the hook body 103. The number of movable sleeves of the telescopic component 203 is not fixed and can be increased or decreased appropriately according to the height of the assembled support beam 101.
