Description

Technical Field

[0001] This utility model relates to the field of lifting hook technology, specifically a lifting hook beam with adjustable hook spacing. Background Technology

[0002] The hook beam is a key load-bearing component in lifting machinery that connects the hook to the pulley block or load-bearing structure. Its design, function, and application scenarios are crucial to the safety and efficiency of lifting operations. However, existing hook beams cannot stably and conveniently control the spacing between hooks. Even if there are beams that can easily adjust the spacing between hooks, they require a lot of automated control equipment, which reduces the strength of the beam and prevents the hook from lifting heavy objects. Therefore, a device is needed to solve the above problems, so that the beam can conveniently and accurately adjust the spacing between hooks according to the needs of use, and can also enable the adjusted hook to lift and hang heavier objects. Utility Model Content

[0003] The purpose of this invention is to provide a hook beam with adjustable hook spacing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hook beam with adjustable hook spacing, comprising a fixed mounting plate, fixed mounting holes, a first fixed mounting bolt, a fixed mounting limiting plate, a second fixed mounting bolt, and a hook moving part. The fixed mounting limiting plate is fixedly mounted on both ends of the limiting adjustment part by the first fixed mounting bolt and the second fixed mounting bolt. The fixed mounting plate is fixedly mounted on the upper end of the fixed mounting limiting plate. The fixed mounting holes are symmetrically opened through the fixed mounting plate. The hook moving parts are symmetrically arranged on the limiting adjustment part.

[0005] Preferably, the limiting adjustment part includes a main sliding limiting support column, an auxiliary support bracket, and a scale line. The auxiliary support bracket is evenly distributed outside the main sliding limiting support column, and the scale line is disposed on the auxiliary support bracket.

[0006] Preferably, the hook moving part includes a locking threaded post, a first sliding groove, a sliding support limiting frame, a second sliding groove, and a hook. The hook is fixedly connected to the bottom of the sliding support limiting frame. The second sliding groove is opened through the middle of the sliding support limiting frame. The first sliding groove is evenly opened through the edge of the sliding support limiting frame. The locking threaded post is evenly threaded into the sliding support limiting frame.

[0007] Preferably, the second fixing bolt is threaded between the end of the fixing limiting plate and the end of the main sliding limiting support column, and the first fixing bolt is threaded between the end of the fixing limiting plate and the end of the auxiliary support bracket.

[0008] Preferably, the main sliding limit support column is slidably engaged inside the second sliding slot.

[0009] Preferably, the auxiliary support bracket is slidably engaged inside the first sliding slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model features a main sliding limit support column that bears the core longitudinal load, while auxiliary support brackets are evenly distributed to provide lateral stability support, forming a dual load-bearing system of main column plus distributed auxiliary brackets. The hook moving part simultaneously nests the main column and auxiliary brackets through the second sliding slot and the first sliding slot, significantly improving bending and torsional resistance and avoiding the strength defects of single-point support. It can maintain high structural rigidity when adjusting the hook spacing, meeting the needs of heavy-duty lifting. The scale lines on the auxiliary support brackets provide an intuitive spacing reference, enabling precise adjustment of the hook spacing and avoiding human visual error. The limit adjustment part is connected to the fixed installation limit plate through the first and second fixed installation bolts, supporting quick disassembly. The auxiliary support brackets are evenly distributed outside the main column, ensuring that the load can be distributed and transmitted through multiple brackets when the hook is in any adjustment position, effectively suppressing beam deformation caused by eccentric loading. Therefore, this device achieves stepless adjustment through a mechanical double-rail sliding structure while ensuring load-bearing strength. It avoids the complexity of automated equipment and breaks through the spacing limitations of traditional fixed beams, balancing the contradictory needs of strength and adjustability.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figure 1-3 An embodiment of this utility model provides a hook beam with adjustable hook spacing, including a fixed mounting plate 1, fixed mounting holes 2, a first fixed mounting bolt 3, a fixed mounting limiting plate 4, a second fixed mounting bolt 5, and a hook moving part 6. The fixed mounting limiting plate 4 is fixedly mounted on both ends of the limiting adjustment part 7 by the first fixed mounting bolt 3 and the second fixed mounting bolt 5. The fixed mounting plate 1 is fixedly mounted on the upper end of the fixed mounting limiting plate 4. The fixed mounting holes 2 are symmetrically opened through the fixed mounting plate 1. The hook moving parts 6 are symmetrically arranged on the limiting adjustment part 7.

[0018] The limit adjustment part 7 includes a main sliding limit support column 8, an auxiliary support bracket 9 and a scale line 10. The auxiliary support bracket 9 is evenly distributed on the outside of the main sliding limit support column 8, and the scale line 10 is set on the auxiliary support bracket 9.

[0019] The hook moving part 6 includes a locking threaded post 11, a first sliding groove 12, a sliding support limiting frame 13, a second sliding groove 14, and a hook 15. The hook 15 is fixedly connected to the bottom of the sliding support limiting frame 13. The second sliding groove 14 is opened through the middle of the sliding support limiting frame 13. The first sliding groove 12 is evenly opened through the edge of the sliding support limiting frame 13. The locking threaded post 11 is evenly threaded into the sliding support limiting frame 13.

[0020] The second fixing bolt 5 is threaded between the fixed installation limit plate 4 and the end of the main sliding limit support column 8, and the first fixing bolt 3 is threaded between the fixed installation limit plate 4 and the end of the auxiliary support bracket 9. The main sliding limit support column 8 and the auxiliary support bracket 9 can be fixedly connected and set up, which can stably lift heavier objects.

[0021] The main sliding limit support column 8 is slidably engaged inside the second sliding slot 14, playing the main supporting and limiting role.

[0022] The auxiliary support bracket 9 is slidably engaged inside the first sliding slot 12, and the evenly distributed auxiliary support brackets 9 play a role in assisting in stabilizing and limiting the position.

[0023] Working principle: During use, the device can be fixedly installed in a designated position through the fixing mounting holes 2 on the fixing mounting plate 1. When it is necessary to adjust the distance between the two hooks 15, the pressure exerted by the front end of the locking threaded column 11 on the auxiliary support bracket 9 sliding into the first sliding slot 12 can be released by turning the locking threaded column 11, thus unlocking the device. This allows the sliding support limit frame 13 to slide along the main sliding limit support column 8 and the auxiliary support bracket 9 to adjust the distance between the two sliding support limit frames 13, thereby adjusting the distance between the two hooks 15. Furthermore, the scale line 10 allows for precise adjustment and control of the distance between the two hooks 15. The main sliding limit support column 8 and the auxiliary support brackets 9 evenly distributed outside the main sliding limit support column 8 can slide into the interior of the second sliding slot 14 and the first sliding slot 12, allowing the hooks 15 to stably hook and lift heavier objects. By removing the first fixing bolt 3 and the second fixing bolt 5, the fixing plate 4 at both ends of the main sliding limit support column 8 and the auxiliary support bracket 9 can be removed, allowing for convenient disassembly, assembly, replacement, and maintenance of the device.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
