Description

Technical Field

[0001] This utility model relates to the technical field of lifting equipment accessories, specifically a hook connector for engineering lifting. Background Technology

[0002] In construction projects, it is common to encounter prefabricated modules or building materials that are too heavy to be moved by manpower alone. Therefore, various cranes, such as tower cranes and truck cranes, are usually used to lift and move construction materials. The hook is usually connected to the pulley structure, and then the pulley is connected to the lifting arm through steel cable, which saves effort.

[0003] In actual lifting operations, hooks typically come in two forms: one where the hook can rotate horizontally, and another where the hook is fixed and cannot rotate horizontally. A horizontally rotating hook allows workers below to use tools to push the object away from it when its orientation is incorrect, thus correcting the object's orientation. This type of hook offers greater flexibility. However, during lifting, the object can easily rotate due to wind or the center of gravity, generating centrifugal force that can damage the lifting structure. While a non-horizontally rotating hook avoids these issues, it lacks flexibility and is difficult to adjust when steel structures, prefabricated components, or other building components are misaligned. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a hook connector for engineering lifting to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hook connector for engineering lifting, comprising a bracket, with motors installed on both sides below the bracket, and a worm gear reducer connected to the output end of the motors, a lead screw connected to the output end of the worm gear reducer, and a friction plate connected to one end of the lead screw, protective shells connected to both sides of the bracket, and batteries installed inside both protective shells, with a wireless controller installed on the top of one of the protective shells.

[0006] By adopting the above technical solution, when the hook body does not need to rotate during hoisting, the motor is remotely started, and the motor output drives the lead screw to rotate through the worm gear reducer. After the lead screw rotates, it drives the friction plate to move and press against the hook body, thereby preventing the hook body from rotating through friction. The worm gear reducer also has self-locking properties, thus improving safety. When the hook body needs to rotate when reaching the loading / unloading position, the motor output drives the lead screw to reverse through the worm gear reducer, thereby causing the friction plate to move in the opposite direction away from the hook body. At this time, the hook can be rotated to adjust its direction.

[0007] Furthermore, the friction plate is threadedly connected to the lead screw, and the friction plate is slidably connected to the bracket.

[0008] By adopting the above technical solution, the motor output end drives the lead screw to rotate through the worm gear reducer, and the rotation of the lead screw drives the friction plate to move.

[0009] Furthermore, the friction plate has a square cross-section on the side near the lead screw, and a semi-circular arc shape on the other side.

[0010] By adopting the above technical solution, the left side of the friction plate is square, which facilitates the guidance of the friction plate and prevents the friction plate from rotating with the lead screw. The right side of the friction plate is semi-circular, which can adapt to the diameter of the hook body, increasing the contact area and thus increasing the friction force.

[0011] Furthermore, the height of one protective shell and one battery below the wireless controller is less than the height of another protective shell and another battery, and both motors and two batteries are electrically connected to the wireless controller.

[0012] By adopting the above technical solution, assuming that the battery and protective shell on the left weigh two kilograms, and the battery, protective shell, and wireless controller on the right weigh three kilograms, then by reducing the size of the battery and protective shell on the right, the weight of both sides of the support can be reduced to two kilograms. This avoids the safety hazards caused by the weight imbalance between the left and right sides of the support due to the battery and wireless controller during hoisting. It should be noted that the weight described in this paragraph is only a hypothetical example and does not represent the actual weight of the battery, protective shell, and wireless controller.

[0013] Furthermore, a pulley is connected to the upper part of the bracket, and a mounting base is connected to the lower part of the bracket, with a hook body penetrating through the bottom of the mounting base.

[0014] By adopting the above technical solution, the hook body is connected to the bracket through the mounting base, and the pulley is connected to the lifting equipment through the steel cable, which makes it easy for the lifting equipment to drive the hook body to move and lift construction materials; and the wireless controller makes it easy to remotely control the start and stop of the motor, and it is powered by the battery, so there is no need to connect the motor to the operator's cab of the lifting equipment through a long cable.

[0015] Furthermore, the friction plate abuts against the hook body.

[0016] By adopting the above technical solution, the lead screw rotates and drives the friction plate to move and press against the hook body, thereby preventing the hook body from rotating through friction. In addition, the worm gear reducer has self-locking properties, thereby improving safety.

[0017] Furthermore, a cover plate is connected to one side of the protective shell, and bolts penetrate both the top and bottom of one side of the cover plate. A second buffer pad is connected to the other side of the cover plate, and a first buffer pad is connected to the inner wall of the protective shell.

[0018] By adopting the above technical solution, when the battery is depleted, the lifting equipment lowers the support to the ground. Then, the staff unscrews the bolts to remove the cover plate and replace the battery. After the battery is replaced, the staff puts the cover plate back on with bolts. After the battery is installed, the first and second buffer pads play a role in shock absorption and heat conduction, reducing the impact of vibration on the battery during hoisting and preventing thermal runaway caused by the inability to dissipate heat when the battery is discharging. In addition, the staff charges the replaced battery for reuse.

[0019] Furthermore, both the first and second buffer pads are thermally conductive silicone pads.

[0020] By adopting the above technical solution, the first and second buffer pads play the roles of shock absorption and heat conduction, reducing the impact of vibration on the battery during hoisting and preventing thermal runaway caused by the inability to dissipate heat during battery discharge.

[0021] Furthermore, the cover plate is detachably connected to the protective shell by bolts, and the battery is detachably connected to the protective shell.

[0022] By adopting the above technical solution, when the battery is depleted, the lifting equipment lowers the support to the ground, and then the staff unscrews the bolts to remove the cover plate to replace the battery. After replacing the battery, the staff puts the cover plate back on with bolts.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through the arrangement of a motor, worm gear reducer, lead screw, and friction plate, allows the hook body to rotate during hoisting when rotation is not required. The motor output drives the lead screw to rotate via the worm gear reducer, which in turn drives the friction plate to displace and press against the hook body. This friction prevents the hook body from rotating, and the worm gear reducer has self-locking properties, thus improving safety. When the hook body needs to rotate at the loading / unloading position, the motor output drives the lead screw to reverse direction via the worm gear reducer, causing the friction plate to displace away from the hook body. The hook can then be rotated to adjust its direction. This design adapts to different environments, allowing for braking or deactivation of the hook body during rotation, resulting in good safety and practicality.

[0025] 2. This utility model, through the setting of a wireless controller and a storage battery, facilitates remote control via the wireless controller, and the storage battery provides power to the motor and the wireless controller, eliminating the need for long cables to connect the lifting equipment and the motor during operation; thus, it is convenient to use.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A hook connector for engineering lifting, such as Figures 1-5As shown, the system includes a bracket 1. Motors 5 are mounted on both sides of the bracket 1 below. A worm gear reducer 6 is connected to the output of motor 5, and a lead screw 7 is connected to the output of worm gear reducer 6. A friction plate 8 is connected to one end of the lead screw 7, and the friction plate 8 is threadedly connected to the lead screw 7. The friction plate 8 is slidably connected to the bracket 1. The side of the friction plate 8 closest to the lead screw 7 has a square cross-section, while the other side has a semi-circular arc shape. The friction plate 8 abuts against the hook body 4. Protective shells 9 are connected to both sides of the bracket 1. Batteries 11 are installed inside both protective shells 9. A wireless controller 10 is mounted on the top of one of the protective shells 9. The height of one protective shell 9 and the battery 11 below the wireless controller 10 is less than that of the other protective shell 9. The height of the shell 9 and the other battery 11, the two motors 5 and the two batteries 11 are all electrically connected to the wireless controller 10. When the hook body 4 does not need to rotate during hoisting, the motor 5 is remotely started. The output end of the motor 5 drives the lead screw 7 to rotate through the worm gear reducer 6. After the lead screw 7 rotates, it drives the friction plate 8 to move and press against the hook body 4, thereby preventing the hook body 4 from rotating through friction. The worm gear reducer 6 has self-locking properties, thereby improving safety. When the hook body 4 needs to rotate when reaching the loading and unloading position, the output end of the motor 5 drives the lead screw 7 to reverse through the worm gear reducer 6, thereby causing the friction plate 8 to move in the opposite direction away from the hook body 4. At this time, the hook can be rotated to adjust its direction.

[0036] See Figures 1-3 In the above embodiment, a pulley 2 is connected to the upper part of the bracket 1, and a mounting base 3 is connected to the lower part of the bracket 1. A hook body 4 passes through the bottom of the mounting base 3. The hook body 4 is connected to the bracket 1 through the mounting base 3, and the pulley 2 is connected to the lifting equipment through a steel cable, which facilitates the lifting equipment to drive the hook body 4 to move and lift construction materials. The wireless controller 10 facilitates the remote control of the motor 5 to start and stop, and it is powered by the battery 11. Therefore, there is no need to connect the motor 5 to the operating room of the lifting equipment through a long cable.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are now implemented to facilitate rapid power restoration.

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 5In the above embodiment, a cover plate 12 is connected to one side of the protective shell 9, and bolts 13 penetrate both the upper and lower sides of one side of the cover plate 12. The cover plate 12 is detachably connected to the protective shell 9 via bolts 13, and the battery 11 is detachably connected to the protective shell 9. A second buffer pad 15 is connected to the other side of the cover plate 12, and a first buffer pad 14 is connected to the inner wall of the protective shell 9. Both the first buffer pad 14 and the second buffer pad 15 are thermally conductive silicone pads. When the battery 11 is depleted, the lifting equipment lowers the support 1 to the ground. Then, the operator unscrews the bolts 13 to remove the cover plate 12 and replaces the battery 11. After replacing the battery 11, the operator reinstalls the cover plate 12 via bolts 13. After the battery 11 is installed, the first buffer pad 14 and the second buffer pad 15 play a role in shock absorption and heat conduction, reducing the impact of vibration on the battery 11 during hoisting and preventing thermal runaway caused by the inability to dissipate heat when the battery 11 is discharging. The operator also charges the replaced battery 11 for reuse.

[0040] The implementation principle of this utility model is as follows: First, the hook body 4 is connected to the bracket 1 through the mounting base 3, and the pulley 2 is connected to the lifting equipment through the steel cable, which makes it easy for the lifting equipment to drive the hook body 4 to move and lift the building materials; and the wireless controller 10 makes it easy to remotely control the start and stop of the motor 5, and it is powered by the battery 11, so there is no need to connect the motor 5 to the operating room of the lifting equipment through a long cable.

[0041] When the hook body 4 does not need to rotate during hoisting, the motor 5 is remotely activated. The output of the motor 5 drives the lead screw 7 to rotate through the worm gear reducer 6. After the lead screw 7 rotates, it drives the friction plate 8 to move and press against the hook body 4, thereby preventing the hook body 4 from rotating through friction. The worm gear reducer 6 has self-locking properties, which improves safety. When the hook body 4 needs to rotate at the loading / unloading position, the output of the motor 5 drives the lead screw 7 to reverse through the worm gear reducer 6, thereby causing the friction plate 8 to move in the opposite direction away from the hook body 4. At this time, the hook can be rotated to adjust its direction.

[0042] When the battery 11 is depleted, the lifting equipment lowers the support 1 to the ground. Then, the workers unscrew the bolts 13 to remove the cover plate 12 and replace the battery 11. After replacing the battery 11, the workers put the cover plate 12 back on using the bolts 13. After the battery 11 is installed, the first buffer pad 14 and the second buffer pad 15 play a role in shock absorption and heat conduction, reducing the impact of vibration on the battery 11 during hoisting and preventing thermal runaway caused by the inability to dissipate heat when the battery 11 is discharging. In addition, the workers charge the replaced battery 11 for reuse.

[0043] It should be noted that since the lifting structure is often in outdoor operation, it is inevitably subject to rain. To prevent water ingress and short circuits in the motor 5, wireless controller 10, and battery 11, the motor 5, wireless controller 10, and battery 11 should be models with an IP68 or higher protection rating, such as underwater motor 5 and waterproof wireless controller 10. In addition, a sealing strip should be installed between the cover plate 12 and the protective shell 9, and the wiring area should be sealed. Furthermore, cables with good waterproof properties, such as silicone cables, should be used.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
