Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical equipment technology, specifically relating to an electrically adjustable leveling crane. Background Technology
[0002] The electrically adjustable leveling crane is a highly efficient and precise lifting device primarily used in industrial, construction, and logistics fields. It achieves smooth lifting through electric drive and is equipped with an automatic leveling function to ensure the load remains horizontal during lifting, effectively preventing tilting or swaying and improving operational safety and efficiency. This equipment is easy to operate, adaptable to various working conditions, and widely used in production lines, warehouse loading and unloading, and high-altitude operations.
[0003] During the transfer of processed aluminum ingots, a non-contact, electrically adjustable horizontal crane is typically used to prevent the processed surface from contacting the lifting gear. During transfer, the electrically adjustable horizontal crane uses a motor, chain, lead screw, and copper nut to move the clamping legs and clamp the two sides of the ingot. When clamped, the copper nut bears a significant clamping force, making it prone to breakage at the flange root. If the copper nut continues to be used after damage, the ingot cannot be clamped properly and is likely to fall during lifting, posing a safety hazard. Simultaneously, the electrode base is highly susceptible to damage during use. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides an electrically adjustable flat hanger, which aims to solve the problems of easy breakage of the copper nut and easy damage of the electrode base of the existing flat hanger, which pose safety hazards.
[0005] This utility model solves the above-mentioned technical problems through the following technical means:
[0006] An electrically adjustable horizontal crane includes a support frame. A connector for connecting to a boom is located at the center of the upper side of the support frame. Two parallel sliding grooves are formed on the support frame. A clamping leg is located at each end of each sliding groove. Guide rails, fixedly connected to the support frame, are provided on both sides of each sliding groove. Sliding blocks are slidably connected to the guide rails. The upper ends of each clamping leg are fixedly connected to the corresponding sliding blocks. A copper nut assembly is located at the center of the upper end of each clamping leg. A bidirectional screw rod, rotatably connected to the support frame, is located within each sliding groove. The two threaded sections of the bidirectional screw rod are threadedly connected to the copper nut assemblies of the corresponding clamping legs. The electrically adjustable horizontal crane also includes a power unit for driving the two bidirectional screw rods to rotate.
[0007] Furthermore, the copper nut assembly includes a baffle and a copper nut fixedly connected to the corresponding clamp leg. A copper nut seat is fitted on the copper nut, and a positioning pin is provided on the copper nut through the copper nut seat. The end of the copper nut seat away from the flange is fixedly connected to the baffle by bolts, and the copper nut is threadedly engaged with the corresponding bidirectional screw.
[0008] Furthermore, the baffle plate has a through hole, the diameter of which is larger than the diameter of the bidirectional screw and smaller than the outer diameter of the non-flange end of the copper nut seat.
[0009] Furthermore, the baffle plate has a through hole, the diameter of which is larger than the diameter of the lead screw and smaller than the outer diameter of the unflanged end of the copper nut.
[0010] Beneficial effects:
[0011] 1. This utility model of an electrically adjustable horizontal crane includes a baffle, a copper nut seat, and bolts. The thickness of the baffle and the number of bolts must be controlled to ensure that the baffle and bolts can withstand 2 to 3 times the force of the copper nut. The non-flange end of the copper nut seat is in tight contact with the baffle without gaps, preventing the copper nut from elongating during operation and ensuring its strength. This structural design prevents the copper nut from breaking, significantly improving its service life and ensuring the safe use of the horizontal crane.
[0012] 2. The electric adjustable leveling device of this utility model is equipped with a motor, bearing housing, transmission shaft, coupling and sprocket, which not only reduces the force on the motor, but also reduces the force on the motor base, thus solving the problem of easy damage to the motor base.

[0019] like Figures 1-3 As shown, this utility model discloses an electrically adjustable horizontal crane, including a support frame 1. A connector for connecting to the boom is provided in the middle of the upper side of the support frame 1. Two parallel sliding grooves are provided on the support frame 1. A clamp leg 2 is installed at each of the left and right ends of each sliding groove. Guide rails 3 are fixedly connected to the support frame 1 on both the front and rear sides of the end of the sliding groove. A slider 4 is slidably connected to each guide rail 3. The upper end of each clamp leg 2 is fixedly connected to the corresponding slider 4. A copper nut assembly is installed in the middle of the upper end of each clamp leg 2. A bidirectional screw 5 is provided in each sliding groove and rotatably connected to the support frame 1. The two threaded sections of the bidirectional screw 5 are threadedly connected to the copper nut assembly of the corresponding clamp leg 2. The electrically adjustable horizontal crane of this utility model is also equipped with a power unit, which is used to drive the two bidirectional screws 5 to rotate.
[0020] As a preferred embodiment, the copper nut assembly includes a baffle 6 and a copper nut fixedly connected to the corresponding clamp leg 2. A copper nut seat 7 is fitted on the copper nut, and a positioning pin is provided on the copper nut through the copper nut seat 7. The end of the copper nut seat 7 away from the copper nut flange is fixedly connected to the baffle 6 by a bolt 8. The copper nut is threadedly engaged with the corresponding bidirectional screw 5.
[0021] As a preferred embodiment, the baffle 6 has a through hole, the diameter of which is larger than the diameter of the bidirectional screw 5 and smaller than the outer diameter of the non-flange end of the copper nut seat 7.
[0022] As a preferred embodiment, the power unit includes a motor 9 mounted on the support frame 1 and two bearing seats 10. A transmission shaft 11 is rotatably connected between the two bearing seats 10. The output end of the motor 9 is connected to the transmission shaft 11 through a coupling 12. The transmission shaft 11 is connected to the bidirectional screw 5 through a sprocket 13. In this embodiment, there are two power units, with one power unit corresponding to one bidirectional screw 5.
[0023] When using this electric adjustable horizontal crane to transfer aluminum ingots, the crane arm first moves the electric adjustable horizontal crane to the target position so that the clamping legs 2 can grip the aluminum ingot to be transferred. After the electric adjustable horizontal crane is moved to the target position, the two sets of motors 9 are started to rotate synchronously. The motors 9 drive the corresponding bidirectional screws 5 to rotate through the coupling 12, transmission shaft 11, and sprocket 13. The bidirectional screws 5 drive the clamping legs 2 at both ends of the slide to move closer together until the clamping legs 2 can stably grip the aluminum ingot to be transferred. After the aluminum ingot is stably gripped, the crane arm transfers the aluminum ingot to the target position. Then, the two sets of motors 9 are started to rotate synchronously in reverse. At this time, the motors 9 drive the bidirectional screws 5 to rotate in the opposite direction. The bidirectional screws 5 drive the clamping legs 2 at both ends of the slide to move away from each other, thereby contacting the clamping legs 2 to grip and limit the aluminum ingot.
[0024] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
