Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting device with anti-collision and anti-damage features. Background Technology

[0002] In industrial production and construction, hoisting equipment is a type of mechanical equipment specifically used for lifting and transporting heavy objects. It can move heavy objects from one location to another, improving the efficiency of material handling. Anti-collision hoisting equipment, on the other hand, is a device that adds anti-collision functions to the traditional hoisting equipment. Its main purpose is to buffer and disperse the collision force through its own structural design and functional mechanism when there is a risk of collision with surrounding objects during hoisting, thereby protecting the hoisted items and the hoisting equipment itself, and reducing the damage and loss caused by the collision.

[0003] A search revealed Chinese Patent Publication No. CN220148998U, which discloses a coil material lifting device, including a lifting tool, a boom, a handle, and reinforcing ribs. The lifting tool is hook-shaped and extends into the interior of the coil material to be lifted. The lifting tool includes a crossbeam and main ribs, with several anti-slip grooves on the crossbeam. The boom is located at the top of the lifting tool and is inclined. The boom and the lifting tool are fixedly connected, and the boom has lifting holes. The handle is located on one side of the lifting tool. The lifting device is fixedly connected, and the lifting device and the boom are reinforced with the reinforcing ribs. This device makes it very convenient to insert the lifting device beam or the extension of the lifting device into the coiled material, solving the cumbersome task of threading the lifting straps, achieving the purpose of rapid lifting and rapid unloading, greatly saving manpower and reducing the overall operation time. During the movement, due to the control of the pull rope, the coiled material will not sway or swing at will, ensuring the safety of the lifting. However, in actual use, the lifted coiled material will sway, causing damage to the edge of the coiled material when it is hit. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a lifting device with anti-collision features, which aims to improve the problem in the prior art where the lifted coils sway, causing damage to the edges of the coils when they are hit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lifting device with anti-collision features, comprising a housing, with fixed blocks fixedly connected to both the front and rear ends of the housing, a sliding groove provided on one side of each of the fixed blocks, a cylinder fixedly connected to one side of each of the sliding grooves, a spring slidably connected to the outer wall of each of the cylinders, a movable column slidably connected to the other end of each of the cylinders, one side of the movable column being in contact with one end of the spring, a connecting block I fixedly connected to one end of each of the movable columns, a rotating plate rotatably connected between adjacent connecting blocks I, a connecting block II rotatably connected to one end of each of the rotating plates, a corresponding baffle fixedly connected to one side of each connecting block II, a movable groove provided on both the left and right sides of the housing, movable blocks fixedly connected to the left and right sides of the inner sides of the two baffles, an extension component provided at the bottom of the baffle, a crossbar slidably connected to the bottom of the housing, a rolled material slidably connected to the outer wall of the crossbar, and a limit mechanism provided on the outer wall of the crossbar.

[0006] Through the above technical solution: when the device collides with surrounding objects during hoisting, the fixed blocks fixedly connected to the front and rear sides and left and right ends of the outer shell play a role. A cylinder is fixedly connected to one side of the sliding groove opened on one side of the fixed block. The spring on the outer wall of the cylinder cooperates with the moving column slidably connected to the other end of the cylinder. When subjected to the collision force, the moving column slides towards the cylinder, compressing the spring. The elastic deformation of the spring plays a buffering role. The connecting block one fixedly connected to one end of the moving column drives the rotating plate to rotate. The connecting block two rotatably connected to the other end of the rotating plate pushes the baffle to move. The baffle slides in the moving groove opened on the left and right sides of the outer shell through the moving blocks fixedly connected to the left and right sides inside, thereby dispersing the collision force and playing a role in preventing collision damage.

[0007] As a further description of the above technical solution:

[0008] The limiting mechanism includes two limiting circular plates. The inner sides of the two limiting circular plates are slidably connected to both ends of the outer wall of the crossbar. Multiple adjustment holes are provided at both ends of the top of the crossbar. Fixed plates are fixedly connected to the opposite sides of the two limiting circular plates. Adjusting bolts are rotatably connected to the top of the two fixed plates. The bottom ends of the two adjusting bolts penetrate the fixed plates. Multiple arc-shaped grooves are provided around the outer walls of the two limiting circular plates. Arc-shaped plates are slidably connected inside the multiple arc-shaped grooves. Multiple insertion holes are equidistantly provided on the opposite sides of the two limiting circular plates. Insertion blocks are slidably connected to one side of the multiple arc-shaped plates. The multiple insertion blocks penetrate the corresponding insertion holes.

[0009] The above technical solution allows for the following: When it is necessary to limit the coil material on the crossbar, the limiting disc is adjusted to a suitable position according to the length of the coil material. At this time, the adjusting bolt is rotated so that its bottom end passes through the fixing plate and is inserted into the corresponding adjusting hole on the crossbar, thereby fixing the limiting disc to the crossbar and preventing it from sliding freely. This achieves the initial limitation of the coil material in the axial direction of the crossbar. When further limitation of the coil material is required, multiple arc-shaped grooves are opened around the outer wall of the limiting disc, and arc-shaped plates are slidably connected to them. According to the diameter of the coil material, the arc-shaped plates can be slid into the arc-shaped grooves to a suitable position, and the insert blocks are inserted into the corresponding insert holes, so that the arc-shaped plates are fixed on the limiting disc. Multiple arc-shaped plates surround the coil material, achieving circumferential limitation of the coil material and ensuring that the coil material is stable during hoisting and will not roll or deviate.

[0010] As a further description of the above technical solution:

[0011] The extension component includes two grooves, which are respectively opened at the bottom of two baffles. An extension plate is slidably connected inside each of the two grooves. Multiple fixing holes are equidistantly opened at the front ends of the left and right sides of the two baffles. Fixing bolts are rotatably connected to the top of the left and right sides of the two extension plates. One end of each of the multiple fixing bolts passes through the corresponding fixing hole.

[0012] Through the above technical solution: when it is necessary to adjust the protection range according to different hoisting environments, the extension component can be used. The extension plate can slide in the groove opened at the bottom of the baffle. After the extension plate is pulled out to a suitable length as needed, the fixing bolts on the top left and right sides of the extension plate are rotated so that one end of it passes through multiple fixing holes opened at equal intervals on the front left and right sides of the baffle to fix the extension plate. When the device is used to hoist the coil, the crossbar slides at the bottom of the shell and the coil slides on the outer wall of the crossbar, realizing the functions of anti-collision and convenient hoisting.

[0013] As a further description of the above technical solution:

[0014] The top left and right sides of the outer shell are fixedly connected to lifting rings, and the top of each of the two lifting rings is fixedly connected to a lifting rope.

[0015] The above technical solution involves connecting the lifting equipment to the crane hook via a sling, and using lifting rings to securely lift the outer shell and the materials it carries.

[0016] As a further description of the above technical solution:

[0017] The upper and lower sides of both ends of the outer shell are provided with sliding grooves, and the upper and lower sides of the multiple movable blocks are fixedly connected with sliders, and the multiple sliders are respectively slidably connected to the interior of the corresponding sliding grooves.

[0018] Through the above technical solution, the baffle moves stably on the outer shell. When the device is subjected to an impact force and the baffle is pushed to move, the slider slides in the groove, which ensures the smoothness and stability of the baffle movement and prevents it from shaking or deviating during the movement.

[0019] As a further description of the above technical solution:

[0020] Both adjusting bolts have slidably connected washers on their outer walls, and the bottoms of the two washers are in contact with the tops of the corresponding fixing plates.

[0021] Through the above technical solution, the main function of the gasket is to increase the contact area between the adjusting bolt and the fixed plate, thereby dispersing the pressure of the adjusting bolt on the fixed plate during the tightening process.

[0022] As a further description of the above technical solution:

[0023] A limiting groove is provided on the front side of the crossbar, and limiting blocks are fixedly connected to the front sides of the inner sides of the two limiting circular plates.

[0024] Through the above technical solution, the limiting block slides in the limiting groove, restricting the rotation of the limiting disc on the crossbar and ensuring the stability of the position of the limiting disc when axially limiting the coil material.

[0025] As a further description of the above technical solution:

[0026] Each of the two limiting circular plates has a rubber pad fixedly connected to one of its adjacent sides, and each of the two rubber pads has a plurality of protrusions fixedly connected at equal intervals to one of its adjacent sides.

[0027] The above technical solution is used to enhance the limiting friction of the coil material and prevent it from sliding on the crossbar.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the cylinder, spring and moving column in the sliding groove of the fixed block on the front and rear sides of the outer shell cooperate with each other. When impacted, the moving column compresses the spring to buffer, and the moving column drives the connecting block one and the rotating plate to rotate. The connecting block two rotates accordingly, pushing the baffle to slide in the moving groove to disperse the impact force. At the same time, the groove at the bottom of the baffle adjusts the position of the extension plate, and the fixing bolt and fixing hole cooperate to fix the extension plate, thus achieving effective anti-collision, adjustment of protection range and hoisting of materials.

[0030] 2. In this utility model, by sliding the limiting circular plate to a suitable position according to the length of the coil, rotating the adjusting bolt through the fixing plate and inserting it into the adjustment hole of the crossbar, the limiting circular plate is fixed to achieve initial axial limitation of the coil. Then, according to the diameter of the coil, the arc plate is slid in the arc groove, and the insert block is inserted into the insertion hole to fix the arc plate. Multiple arc plates surround the coil, ensuring that the coil is stable during hoisting and does not roll or shift, effectively improving the safety and stability of coil hoisting.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a lifting device with anti-collision features, comprising a housing 1, with fixed blocks 3 fixedly connected to its front, rear, left, and right ends. The fixed blocks 3 are used to connect and support subsequent anti-collision structures. Each of the multiple fixed blocks 3 has a sliding groove 4 on one side, and a cylinder 5 is fixedly connected to one side of each sliding groove 4. The cylinder 5 serves as a support shaft for springs 6 and movable columns 7, ensuring the accuracy of their sliding direction. Springs 6 are slidably connected to the outer walls of the multiple cylinders 5. When subjected to impact force, the springs 6 undergo elastic deformation, buffering the impact energy. Movable columns 7 are slidably connected to the other ends of the multiple cylinders 5. Under the action of impact force, the movable columns 7 slide along the cylinders 5, pushing the subsequent structures to move. One side of the movable column 7 is in contact with one end of the spring 6. The spring 6 provides buffer support for the moving columns 7. One end of each of the multiple moving columns 7 is fixedly connected to a connecting block 8, which connects the moving columns 7 to the rotating plate 9, transmitting the moving force of the moving columns 7. Rotating plates 9 are rotatably connected between adjacent connecting blocks 8. The rotating plates 9 rotate under the push of the connecting blocks 8, changing the direction of force transmission. One end of each of the multiple rotating plates 9 is rotatably connected to a connecting block 10, which connects the rotating plates 9 to the baffle 11, converting the rotation of the rotating plates 9 into the moving force of the baffle 11. A corresponding baffle 11 is fixedly connected to one side of each connecting block 10. After being subjected to collision force, the baffle 11 blocks and buffers the colliding object, preventing injury from impact. The left and right sides of the outer casing 1 are provided with... The movable groove 12 provides a guide track for the movement of the baffles 11. Movable blocks 13 are fixedly connected to the left and right sides of the interior of both baffles 11. The movable blocks 13 cooperate with the movable groove 12 to ensure that the baffles 11 move stably on the outer shell 1. An extension component is provided at the bottom of the baffles 11 to adjust the protective length of the baffles 11 according to different usage scenarios. A crossbar 18 is slidably connected to the bottom of the outer shell 1. The crossbar 18 is used to support and move the coil 19, facilitating hoisting operations of the coil 19. The outer wall of the crossbar 18 is slidably connected to the coil 19, enabling the placement and movement of the coil 19 on the crossbar 18. A limit mechanism 2 is provided on the outer wall of the crossbar 18 to limit the position of the coil 19 on the crossbar 18 and prevent it from sliding. The extension assembly includes two grooves 14, which provide space for the installation and sliding of the extension plate 15. The two grooves 14 are respectively located at the bottom of the two baffles 11, facilitating the connection between the extension plate 15 and the baffles 11 and its downward extension. The extension plate 15 is slidably connected inside each of the two grooves 14. By sliding the extension plate 15, the overall length of the baffles 11 can be increased, expanding the protection range. Multiple fixing holes 16 are equidistantly provided on the left and right front ends of each of the two baffles 11. The fixing holes 16 cooperate with fixing bolts 17 to fix the extension plate 15 at different extended length positions. Fixing bolts 17 are rotatably connected to the top of the left and right sides of each of the two extension plates 15. By rotating the fixing bolts 17, they pass through the fixing holes 16, thus fixing the extension plate 15.One end of each of the multiple fixing bolts 17 passes through a corresponding fixing hole 16, completing the fixed connection between the extension plate 15 and the baffle 11, and ensuring the structural stability of the extended baffle 11;

[0040] Specifically, when the device may collide with surrounding objects during hoisting, the fixing blocks 3 fixedly connected to the front, rear, left, and right ends of the outer shell 1 function. A cylinder 5 is fixedly connected to one side of a sliding groove 4 on one side of the fixing block 3. A spring 6 on the outer wall of the cylinder 5 cooperates with a movable column 7 slidably connected to the other end of the cylinder 5. When subjected to a collision force, the movable column 7 slides towards the cylinder 5, compressing the spring 6. The elastic deformation of the spring 6 provides a buffering effect. A connecting block 1 8 fixedly connected to one end of the movable column 7 drives the rotating plate 9 to rotate. A connecting block 2 10 rotatably connected to the other end of the rotating plate 9 pushes the baffle 11 to move. The baffle 11 moves via the movable blocks fixedly connected to the left and right sides inside. 13 slides within the movable grooves 12 on the left and right sides of the outer shell 1, thereby dispersing the collision force and achieving the effect of preventing collision damage. When it is necessary to adjust the protection range according to different hoisting environments, the extension component can be used. The extension plate 15 can slide within the groove 14 at the bottom of the baffle 11. After the extension plate 15 is pulled out to a suitable length as required, the fixing bolts 17 on the top of the left and right sides of the extension plate 15 are rotated so that one end of it passes through multiple fixing holes 16 equidistantly opened at the front end of the left and right sides of the baffle 11, and the extension plate 15 is fixed. When the device is used to hoist the coil 19, the crossbar 18 slides at the bottom of the outer shell 1, and the coil 19 slides on the outer wall of the crossbar 18, realizing the functions of preventing collision damage and convenient hoisting.

[0041] Reference Figure 4 and Figure 5The limiting mechanism 2 includes two limiting circular plates 201, which are used to axially limit the coiled material 19 on the crossbar 18. The inner sides of the two limiting circular plates 201 are slidably connected to the two ends of the outer wall of the crossbar 18, so that the position of the limiting circular plates 201 can be adjusted according to the length of the coiled material 19. Multiple adjustment holes 202 are provided at both ends of the top of the crossbar 18. The adjustment holes 202 cooperate with the adjustment bolts 204 to fix the position of the limiting circular plates 201 on the crossbar 18. The two limiting circular plates 201 are fixed on opposite sides. A fixed plate 203 is fixedly connected to the crossbar 18, providing installation and rotation support for the adjusting bolts 204. The tops of both fixed plates 203 are rotatably connected to the adjusting bolts 204. By rotating, the adjusting bolts 204 can pass through the fixed plates 203 and insert into the adjusting holes 202 on the crossbar 18. The bottom ends of both adjusting bolts 204 pass through the fixed plates 203, locking the position of the limiting circular plates 201 on the crossbar 18. Multiple arc-shaped grooves 205 are formed around the outer walls of both limiting circular plates 201. The arc-shaped grooves 205 are for... The curved plate 206 provides a sliding track, and multiple curved grooves 205 are slidably connected to the interior of the curved plate 206. The curved plate 206 can slide within the curved grooves 205 to accommodate coils 19 of different diameters. Multiple insertion holes 207 are equidistantly provided on the opposite sides of the two limiting circular plates 201. The insertion holes 207 cooperate with insertion blocks 208 to fix the position of the curved plate 206 on the limiting circular plates 201. Insertion blocks 208 are slidably connected to one side of each of the multiple curved plates 206. The insertion blocks 208 can be inserted into the insertion holes 207, thereby securing the plate. The fixed arc plate 206 has multiple inserts 208 passing through corresponding insert holes 207, so that the arc plate 206 is stably installed on the limiting circular plate 201. Rubber pads 27 are fixedly connected to adjacent sides of the two limiting circular plates 201. The rubber pads 27 increase the friction between the rubber pads 27 and the coil 19 to prevent the coil 19 from sliding. Multiple protrusions 28 are fixedly connected at equal intervals to adjacent sides of the two rubber pads 27. The protrusions 28 further increase the friction between the rubber pads 27 and the coil 19, and can also be embedded into the surface of the coil 19 to a certain extent to enhance the limiting effect.

[0042] Specifically, when it is necessary to limit the coil 19 on the crossbar 18, the limiting circular plate 201 is adjusted to a suitable position according to the length of the coil 19. At this time, the adjusting bolt 204 is rotated so that its bottom end passes through the fixing plate 203 and is inserted into the corresponding adjusting hole 202 on the crossbar 18, thereby fixing the limiting circular plate 201 on the crossbar 18 and preventing it from sliding freely, thus achieving the initial limitation of the coil 19 in the axial direction of the crossbar 18. When further limitation of the coil 19 is required, multiple arc-shaped openings around the outer wall of the limiting circular plate 201 are used. Inside the groove 205, an arc-shaped plate 206 is slidably connected. According to the diameter of the coil 19, the arc-shaped plate 206 can be slid into the appropriate position in the arc-shaped groove 205. The insert block 208 is inserted into the corresponding insertion hole 207, so that the arc-shaped plate 206 is fixed on the limiting circular plate 201. Multiple arc-shaped plates 206 surround the coil 19 to achieve circumferential limiting of the coil 19, ensuring that the coil 19 is stable during hoisting and will not roll or deviate. This is used to enhance the limiting friction of the coil 19 and prevent the coil 19 from sliding on the crossbar 18.

[0043] Reference Figure 1 , Figure 4 and Figure 5 Lifting rings 20 are fixedly connected to the top left and right sides of the outer casing 1. The lifting rings 20 are used to connect the lifting ropes 21, providing a connection point for the entire device to external lifting equipment. The top of each of the two lifting rings 20 is fixedly connected to the lifting ropes 21, which are connected to the crane lifting equipment to lift the device and the materials it carries. The upper and lower sides of both ends of the outer casing 1 are provided with sliding grooves 22. The sliding grooves 22 provide sliding tracks for the sliders 23, allowing the components connected to the sliders 23 to move stably. The upper and lower sides of multiple moving blocks 13 are fixedly connected to sliders 23. The sliders 23 are connected to the moving blocks 13, converting the movement of the moving blocks 13 into sliding within the sliding grooves 22. The multiple sliders 23 are respectively slidably connected to the interior of the corresponding sliding grooves 22 to ensure that the moving blocks 13... 3 and related components slide smoothly on the outer shell 1. The outer walls of the two adjusting bolts 204 are slidably connected with washers 24. The washers 24 can increase the contact area between the adjusting bolts 204 and the fixing plate 203. The bottom of the two washers 24 fits against the top of the corresponding fixing plate 203 to prevent damage to the fixing plate 203 when the adjusting bolts 204 are tightened, and at the same time enhance the fixing stability. The front side of the crossbar 18 is provided with a limit groove 25. The limit groove 25 provides a sliding track for the limit block 26 to limit the rotation of the limit plate 201. The inner front side of the two limit plates 201 is fixedly connected with the limit block 26. The limit block 26 slides in the limit groove 25 to ensure that the limit plate 201 is fixed in position on the crossbar 18 and will not rotate arbitrarily.

[0044] Specifically, the hoisting equipment is connected to the crane hook via the hoisting rope 21. The outer shell 1 and the material it carries are securely lifted with the help of the lifting ring 20. The baffle 11 moves stably on the outer shell 1. When the device is subjected to an impact force, pushing the baffle 11 to move, the slider 23 slides in the slide groove 22, ensuring the smoothness and stability of the movement of the baffle 11 and preventing it from shaking or deviating during the movement. The main function of the shim 24 is to increase the contact area between the adjusting bolt 204 and the fixing plate 203, thereby dispersing the pressure of the adjusting bolt 204 on the fixing plate 203 during the tightening process. The limiting block 26 slides in the limiting groove 25, restricting the rotation of the limiting circular plate 201 on the crossbar 18, and ensuring the stability of the position of the limiting circular plate 201 when axially limiting the coil 19.

[0045] Working principle: When the device collides with surrounding objects during hoisting, the fixed blocks 3, which are fixedly connected to the front, rear, left, and right ends of the outer shell 1, function. A cylinder 5 is fixedly connected to one side of a sliding groove 4 on one side of the fixed block 3. A spring 6 on the outer wall of the cylinder 5 cooperates with a movable column 7 slidably connected to the other end of the cylinder 5. When subjected to a collision force, the movable column 7 slides towards the cylinder 5, compressing the spring 6. The elastic deformation of the spring 6 provides a buffering effect. A connecting block 8, fixedly connected to one end of the movable column 7, drives the rotating plate 9 to rotate. A connecting block 10, rotatably connected to the other end of the rotating plate 9, pushes the baffle 11 to move. The baffle 11 moves via the movable blocks 8 fixedly connected to the left and right sides inside. Block 13 slides in the movable grooves 12 opened on the left and right sides of the outer shell 1, thereby dispersing the collision force and achieving the effect of preventing collision damage. When it is necessary to adjust the protection range according to different hoisting environments, the extension component can be used. The extension plate 15 can slide in the groove 14 opened at the bottom of the baffle 11. After the extension plate 15 is pulled out to a suitable length as required, the fixing bolts 17 on the top of the left and right sides of the extension plate 15 are rotated so that one end of it passes through the multiple fixing holes 16 opened at equal intervals on the front of the left and right sides of the baffle 11, and the extension plate 15 is fixed. When the device is used to hoist the coil 19, the crossbar 18 slides at the bottom of the outer shell 1, and the coil 19 slides on the outer wall of the crossbar 18, thus realizing the function of preventing collision damage during hoisting.

[0046] Furthermore, when it is necessary to limit the coil 19 on the crossbar 18, the limiting circular plate 201 is adjusted to a suitable position according to the length of the coil 19. At this time, the adjusting bolt 204 is rotated so that its bottom end passes through the fixing plate 203 and is inserted into the corresponding adjusting hole 202 on the crossbar 18, thereby fixing the limiting circular plate 201 on the crossbar 18 and preventing it from sliding freely, thus achieving the initial limitation of the coil 19 in the axial direction of the crossbar 18. When further limitation of the coil 19 is required, the limiting circular plate... Multiple arc-shaped grooves 205 are opened around the outer wall of 201, and arc-shaped plates 206 are slidably connected therein. According to the diameter of the coil 19, the arc-shaped plates 206 can be slid into the appropriate position in the arc-shaped grooves 205, and the insert blocks 208 are inserted into the corresponding insert holes 207, so that the arc-shaped plates 206 are fixed on the limiting circular plates 201. Multiple arc-shaped plates 206 surround the coil 19, thereby limiting the circumferential movement of the coil 19 and ensuring that the coil 19 is stable during hoisting and will not roll or deviate.
