Description

Technical Field

[0001] This utility model relates to the field of lifting equipment, and in particular to a telescopic beam assembly for a container lifting equipment. Background Technology

[0002] Container spreaders are specialized equipment used for loading and unloading containers in ports, docks, and storage yards. Working in conjunction with quay cranes, gantry cranes, and other lifting equipment, they enable the rapid grabbing, lifting, and precise placement of containers. A container spreader typically consists of an outer cylinder, telescopic beams, and sliding plates. The outer cylinder, usually referring to the external support frame of the spreader, is often welded from high-strength steel and forms the main structural outline of the spreader, providing support and load-bearing capacity. The telescopic beam is usually composed of multiple nestable metal beams, which extend and retract via hydraulic or electric drive. Its core function is to accommodate containers of different sizes. The sliding plate is a sliding component installed at the bottom of the spreader or in the guide plate system, providing guidance, positioning, and shock absorption.

[0003] Due to the reciprocating movement of the telescopic beam, the sliding plate wears down. The surface flatness of the worn sliding plate decreases, the guiding function fails, and the telescopic beam sags after extension, making it difficult to align the spreader with the container corner fittings. This prolongs the single loading and unloading cycle time, directly affecting the port's throughput. In addition, severely worn sliding plates cannot effectively cushion the load, easily causing fatigue cracks in the telescopic beam, requiring downtime for maintenance. Therefore, worn sliding plates need to be replaced promptly. Since the sliding plate is located inside the outer cylinder, it is difficult to visually inspect the wear condition. In the current technology, the wear condition can only be checked after disassembling the telescopic beam during periodic maintenance to determine whether replacement is necessary.

[0004] Using a periodic disassembly and inspection method has two drawbacks. First, it cannot guarantee the timely replacement of worn-out slide plates, which may have already caused wear and tear on components on the telescopic beam and other lifting equipment. Second, there is also the possibility that the slide plates may not need to be replaced after disassembly, resulting in a waste of time and labor. Utility Model Content

[0005] To address the technical problem of the inability to accurately monitor the wear condition of the slip plate in the prior art, this utility model provides a container spreader telescopic beam assembly that can accurately monitor the wear condition of the slip plate, facilitating timely replacement of worn slip plates.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a container spreader telescopic beam assembly, including an outer cylinder, an axially movable telescopic beam inside the outer cylinder, and sliding plates on the four inner walls of the outer cylinder, wherein the telescopic beam and the sliding plates can generate sliding friction. It also includes a detection unit, which includes a mounting cap disposed on the sliding plate. The mounting cap is made of insulating material, and a detection wire is disposed on the detection surface of the mounting cap. The distance between the detection wire and the working surface of the sliding plate is a preset alarm distance. The detection wire connects a power supply and an indicator light in series. The indicator light is located outside the outer cylinder. When the detection wire is worn and broken, the indicator light goes out.

[0007] This invention, by setting a detection unit with a detection wire, enables the detection wire to be exposed when the slide plate wears down to a set thickness. The detection wire is then broken by the wear of the telescopic beam, causing the electrical connection between the power supply and the indicator light to be broken, preventing conductivity and turning off the indicator light. This allows maintenance personnel to promptly detect when the slide plate is worn down to the required thickness and replace it, avoiding untimely replacement and wasted disassembly and assembly labor.

[0008] Furthermore, the mounting cap is threadedly connected to the slide plate.

[0009] This utility model uses a mounting cap to connect to the slide plate via a threaded connection, which allows for adjustment of the distance between the detection wire and the working surface of the slide plate according to the working conditions, thereby achieving the function of adjusting the set wear thickness of the slide plate and improving the flexibility of use.

[0010] Furthermore, the detection unit also includes a mounting cylinder, which is coaxially arranged and threadedly connected to the mounting cap. The power supply is disposed inside the mounting cylinder, and both ends of the detection wire extend into the mounting cylinder. The mounting cylinder passes through the slide plate and extends out of the outer cylinder. A lamp is screwed to the end of the mounting cylinder extending out of the outer cylinder, and an indicator light is disposed on the lamp.

[0011] This invention achieves a modular design for the detection unit by setting up an installation cylinder, which facilitates overall installation.

[0012] Furthermore, the power source includes a battery compartment and a battery. The battery is detachably disposed in the battery compartment. The battery compartment has a first terminal and a second terminal at its two ends. One end of the detection wire is detachably connected to the first terminal, and the other end of the detection wire is detachably connected to the indicator light. The indicator light is connected to the second terminal via a wire.

[0013] This invention enables the replacement of batteries and detection wires through a battery compartment and wiring posts, facilitating the maintenance of the detection unit.

[0014] Furthermore, two sliding plates are respectively provided on the inner wall of each outer cylinder.

[0015] This invention enhances the support for the telescopic beam by incorporating more sliding plates.

[0016] Furthermore, the skateboard includes a skateboard body, on which a wear-resistant layer is provided. The wear-resistant layer generates sliding friction with the telescopic beam, and the detection wire is located within the wear-resistant layer.

[0017] This invention extends the service life of the skateboard by adding a wear-resistant layer.

[0018] Furthermore, the wear-resistant layer is provided with grease grooves.

[0019] This invention can store grease by setting a grease tank, thus extending the service life of the wear-resistant layer.

[0020] Furthermore, the wear-resistant layer is made of tin bronze.

[0021] Furthermore, the slide plate is connected to the outer cylinder by connecting bolts.

[0022] As can be seen from the above technical solutions, this utility model has the following advantages:

[0023] This utility model provides a container spreader telescopic beam assembly. By incorporating a detection unit with a detection wire, the detection wire is exposed when the slide plate wears to a set thickness. The wire is then worn away by the telescopic beam, causing the electrical connection between the power supply and the indicator light to break, preventing conductivity and extinguishing the indicator light. This allows maintenance personnel to promptly detect when the slide plate is worn to the required thickness and replace it, avoiding delays and wasted disassembly and assembly labor. The installation cap connects to the slide plate via threads, allowing adjustment of the distance between the detection wire and the slide plate's working surface according to operating conditions, thus adjusting the set wear thickness and improving operational flexibility. The modular design of the detection unit, achieved through the installation cylinder, facilitates overall installation. The battery compartment and wiring posts enable battery and detection wire replacement, simplifying maintenance. Multiple slide plates enhance support for the telescopic beam. A wear-resistant layer extends the slide plate's lifespan. A grease reservoir stores grease, further extending the wear-resistant layer's lifespan. Attached Figure Description

[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0032] like Figures 1 to 3As shown in the figure, this specific embodiment provides a container spreader telescopic beam assembly, including an outer cylinder 2, a telescopic beam 1, a sliding plate 4, and a detection unit 3. The telescopic beam 1 is axially movable inside the outer cylinder 2, and sliding plates 4 are provided on each of the four inner walls of the outer cylinder 2. The telescopic beam 1 and the sliding plates 4 can generate sliding friction. The detection unit 3 includes a mounting cap 301, which is disposed on the sliding plate 4. The mounting cap 301 is made of insulating material, and a detection wire 302 is provided on the detection surface of the mounting cap 301. The detection surface of the mounting cap 301 interacts with the working surface of the sliding plate 4 (and the telescopic beam). 1. The surfaces that generate relative sliding are arranged in parallel. The distance between the detection wire 302 and the working surface of the slide plate 4 is a preset alarm distance. The detection wire 302 connects the power supply 305 and the indicator light 306 in series. The indicator light 306 is located outside the outer cylinder 2. When the detection wire 302 is worn off, the indicator light 306 goes out. During the reciprocating movement of the telescopic beam 1, the working surface of the slide plate 4 is continuously worn down, making the thickness of the slide plate 4 thinner. After reaching the set thickness, the detection wire 302 is exposed. The telescopic beam 1 quickly wears off the detection wire 302, thereby turning off the indicator light 306.

[0033] This specific embodiment, by setting a detection unit 3 with a detection wire 302, enables the detection wire 302 to be exposed when the slide plate 4 wears down to a set thickness. The detection wire 302 is worn away by the telescopic beam 1 and thus disconnected, causing the electrical connection between the power supply 305 and the indicator light 306 to be broken and unable to conduct electricity. The indicator light 306 then goes out, allowing maintenance personnel to promptly detect that the slide plate 4 is worn to the point where it needs to be replaced, avoiding untimely replacement and wasted disassembly and assembly labor.

[0034] Because different specifications of lifting tools operate under different conditions, the wear degree of the slide plate 4 varies, and the alarm timing of the detection unit 3 also differs. To improve the flexibility of the detection unit 3, such as... Figure 3 and Figure 4 As shown, the slide plate 4 is provided with a threaded hole, and the outer circumference of the mounting cap 301 is provided with an external thread. The mounting cap 301 is threadedly connected to the slide plate 4. Furthermore, in order to facilitate the accommodation of the detection wire 302, the detection surface of the mounting cap 301 is provided with a receiving groove. The bottom of the receiving groove is provided with two through holes. The two ends of the detection wire 302 pass through the through holes and penetrate the mounting cap 301. A portion of the detection wire 302 is located in the receiving groove and protrudes from the receiving groove. In this specific embodiment, the mounting cap 301 is made of hard plastic.

[0035] To make the detection unit 3 modular and easy to install, such as Figure 3As shown, in this specific embodiment, the detection unit 3 further includes a mounting cylinder 303. The outer surface of the end of the mounting cylinder 303 is threaded. The mounting cylinder 303 is coaxially arranged with and threadedly connected to the mounting cap 301. The power supply 305 is disposed inside the mounting cylinder 303. Both ends of the detection wire 302 extend into the mounting cylinder 303. The mounting cylinder 303 passes through the slide plate 4 and extends out of the outer cylinder 2. A lamp tube 304 is screwed to the end of the mounting cylinder 303 extending out of the outer cylinder 2. An indicator light 306 is disposed on the lamp tube 304. This arrangement facilitates maintenance personnel in promptly detecting indicator lights 306 that are extinguished, flashing, or have insufficient brightness. Furthermore, as... Figure 5 As shown, to facilitate the replacement of the detection lead 302 and the battery 3056, the power supply 305 includes a battery compartment and a battery 3056. The battery 3056 is detachably installed in the battery compartment. The battery compartment has a first terminal 3051 and a second terminal 3052 at its two ends. One end of the detection lead 302 is detachably connected to the first terminal 3051, and the other end is detachably connected to the indicator light 306. The indicator light 306 is connected to the second terminal 3052 via a wire. Specifically, the battery compartment includes a threaded cylindrical body 3054 and a cover 3055. The cylindrical body 3054 has heat dissipation grooves. The first terminal 3051 is located at one end of the cylindrical body 3054 and electrically connected to the internal electrode plates. The second terminal 3052 is located at the cover 3055. One end of 055 is electrically connected to the conductive spring inside the cover 3055. Both terminal 1 (3051) and terminal 2 (3052) have wiring holes, and studs 3053 are installed inside the wiring holes. One end of the detection wire 302 is wound and connected to the stud 3053 on terminal 1 (3051). A conductive sheet is installed inside the lamp holder 304. One end of the conductive sheet contacts the indicator light 306, and the other end also has a wiring hole and a stud 3053. The other end of the detection wire 302 is wound and connected to the stud 3053 on the conductive sheet. The battery 3056 should have a lifespan longer than the slide plate 4. In this specific embodiment, the battery 3056 has a lifespan of 20 months. The indicator light 306 is an energy-saving lamp. If the brightness of the indicator light 306 decreases, the battery 3056 needs to be replaced promptly.

[0036] like Figure 2 As shown, in order to enhance the supporting and buffering effect of the slide plate 4, in this specific embodiment, two slide plates 4 are respectively provided on the inner wall of each outer cylinder 2, and the length of the slide plate 4 is the same as the length of the outer cylinder 2.

[0037] like Figure 4As shown, to improve the wear resistance of the skateboard 4, in this specific embodiment, the skateboard 4 includes a skateboard body 402, and a wear-resistant layer 401 is also provided on the skateboard body 402. The wear-resistant layer 401 generates sliding friction with the telescopic beam 1, and the detection wire 302 is located inside the wear-resistant layer 401. A grease groove 404 is provided on the wear-resistant layer 401. By providing the grease groove 404, grease can be stored, extending the service life of the wear-resistant layer 401. In this specific embodiment, the wear-resistant layer 401 is made of tin bronze material.

[0038] like Figure 4 As shown, in this specific embodiment, the slide plate 4 and the outer cylinder 2 are connected by connecting bolts 5. The wear-resistant layer 401 of the slide plate 4 is provided with countersunk holes 403. In order to improve the sealing performance, waterproof foam is provided in the gap between the outer cylinder 2 and the bolt, and in the gap between the mounting cylinder 303 and the outer wall.

[0039] In this specific embodiment, the detection unit 3 is set at the position of the skateboard 4 with greater wear, which can be determined based on past experience. Furthermore, each of the eight skateboards 4 in this specific embodiment is equipped with an individual detection unit 3, which can accurately determine which skateboard 4 needs to be replaced.

[0040] The inspection process for the telescopic beam assembly of this container spreader is as follows:

[0041] According to the working conditions, adjust the depth of the mounting cap 301 of the detection unit 3 in the wear-resistant layer 401 to ensure that the detection surface of the mounting cap 301 is located at the position where the slide plate 4 is worn to the required level. When the slide plate 4 is worn to the required level, the detection guide is exposed and is worn by the telescopic beam 1, thus opening the slide plate 4. The indicator light 306 goes out, and the corresponding slide plate 4 needs to be replaced.

[0042] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0043] 1. By setting a detection unit 3 with a detection wire 302, when the slide plate 4 is worn to a set thickness, the detection wire 302 is exposed. The detection wire 302 is worn away by the telescopic beam 1 and thus disconnected, causing the electrical connection between the power supply 305 and the indicator light 306 to be broken and unable to conduct electricity. The indicator light 306 then goes out, allowing maintenance personnel to promptly detect that the slide plate 4 is worn to the point where it needs to be replaced, thus avoiding untimely replacement and wasted disassembly and assembly labor.

[0044] 2. By connecting the mounting cap 301 to the slide plate 4 via a thread, the distance between the detection wire 302 and the working surface of the slide plate 4 can be adjusted according to the working conditions, thereby achieving the function of adjusting the set wear thickness of the slide plate 4 and improving the flexibility of use;

[0045] 3. By setting the mounting cylinder 303, the modular design of the detection unit 3 is realized, which facilitates the overall installation;

[0046] 4. The battery 3056 and the detection wire 302 can be replaced through the battery compartment and the wiring post, which facilitates the maintenance of the detection unit 3;

[0047] 5. By setting more sliding plates 4, the support for the telescopic beam 1 can be enhanced;

[0048] 6. The service life of the skateboard 4 can be extended by setting the wear-resistant layer 401;

[0049] 7. The grease tank 404 can store grease, extending the service life of the wear-resistant layer 401.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
