Description

Technical Field

[0001] This utility model relates to the field of lifting technology, specifically to a gantry crane with a mobile maintenance platform. Background Technology

[0002] In modern industrial production, large-scale mold processing and assembly equipment plays a crucial role, and its stable and efficient performance directly affects product quality and production efficiency. However, in actual production processes, especially when production space is significantly limited, the cleaning and maintenance of these large pieces of equipment often face numerous challenges.

[0003] Traditionally, when cleaning or repairing perforating pins in large mold processing and assembly equipment, the usual practice is to hoist the pins from the equipment to the ground. This process requires specialized hoisting equipment, and due to the large size and weight of the pins, the hoisting operation itself is inherently difficult and risky. Furthermore, the stability and safety of the pins must be ensured during hoisting to avoid equipment damage or personal injury due to improper operation. After the pins are hoisted to the ground, workers then clean and repair them. However, this method has many drawbacks.

[0004] First, relocating perforating needles over a large area consumes a significant amount of time and manpower. From hoisting them onto the equipment and transporting them to the ground, to reinstalling them back onto the equipment after repair, the entire process requires coordination and cooperation across multiple stages. Delays in any stage can extend the entire repair cycle. This not only affects the normal operation of the equipment but may also disrupt the entire production schedule, causing unnecessary economic losses.

[0005] Secondly, precise positioning is required when reassembling the perforating needles. Due to the complex structure of the equipment, the precision requirements for the fit between various components are very high. If the assembly position of the perforating needles is deviated, it may lead to unstable operation of the equipment or even cause malfunctions. Therefore, workers need to spend a lot of time and effort on positioning and adjustment when reassembling the perforating needles, which not only increases the labor intensity of workers but also seriously reduces work efficiency.

[0006] Furthermore, traditional working methods also present certain safety hazards. During hoisting and transportation, improper operation or equipment malfunction may cause the perforating needle to fall or collide, resulting in personal injury or equipment damage. Simultaneously, workers performing maintenance and cleaning work also face various potential hazards, such as electrical hazards and mechanical injuries, further increasing the overall risk of the work.

[0007] To address the above issues, using a mobile inspection platform is a more reasonable technical solution. However, there are no existing mobile inspection platforms available for perforated needles, and separate development is required for this application.

[0008] To address the aforementioned issues, those skilled in the art urgently need to develop a dedicated, new mobile maintenance platform. Utility Model Content

[0009] The purpose of this utility model is to address the shortcomings of existing technologies by providing a gantry crane with a mobile maintenance platform that offers higher construction efficiency, greater safety, and greater specificity.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is: a gantry crane with a mobile maintenance platform, comprising a movable gantry frame, a transverse lifting unit, a first mobile platform, and a second mobile platform. The span of the portal frame is greater than the width of the mold assembly table to be inspected, and it is used to span across the top of the mold assembly table to be inspected. The top crossbeam of the portal frame is provided with at least two layers of traveling rails. The lateral lifting unit travels on the upper traveling rail to lift the perforating pins on the assembly table of the mold to be repaired. The first and second mobile platforms are suspended on the lower travel track and located on both sides of the transverse lifting unit to provide manual maintenance workstations.

[0011] Preferably, the outermost ends of the first and second mobile platforms move to the support legs of the portal frame.

[0012] Preferably, the heights of the first and second mobile platforms are adjustable.

[0013] Preferably, the legs of the portal frame are provided with ladders corresponding to the height settings of the first and second moving platforms.

[0014] Preferably, the lateral lifting unit includes a lateral trolley and a lifting assembly, the lateral trolley travels on an upper travel track, and the lifting assembly is mounted on the lateral trolley.

[0015] Preferably, both the first and second mobile platforms include a drive assembly, a mobile trolley frame, a platform connecting bracket, and a platform. The mobile trolley frame travels on the lower travel track via the drive assembly, and the platform is installed below the mobile trolley frame via the connecting bracket.

[0016] Preferably, the first mobile platform and the second mobile platform have the same specifications.

[0017] Preferably, the platform is equipped with guardrails.

[0018] Preferably, the drive assembly includes a drive motor and a drive wheel set.

[0019] This utility model has substantial features and advancements compared to existing technologies. Specifically, based on a portal frame structure, it features two layers of walking tracks on the top crossbeam, upon which a horizontal lifting unit is installed. By adjusting the lifting position through horizontal movement, the perforating needle is lifted to the desired location using the lifting assembly. Then, by controlling the first and second moving platforms to move to both sides of the perforating needle, workers can stand on the two moving platforms to clean and inspect the needle. Compared to the traditional solution that requires frequent hoisting, moving, and installation of the perforating needle, this method significantly improves efficiency and safety, and can be specifically used for the maintenance of perforating needles.

Detailed Implementation

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0026] like Figures 1-4 As shown, a gantry crane with a mobile maintenance platform includes a mobile gantry frame 1, a transverse lifting unit 2, a first mobile platform 3, and a second mobile platform 4.

[0027] The span of the portal frame 1 is greater than the width of the mold assembly platform 5 to be repaired, and it is used to span across the top of the mold assembly platform 5 to be repaired, forming a portal crane. The perforating needle 6 is placed on the mold assembly platform 5 to be repaired.

[0028] The top crossbeam 11 of the portal frame 1 is provided with two layers of walking rails. The transverse lifting unit 2 travels on the upper walking rail 13 and is used to lift the perforating needles 6 on the mold assembly table 5 to be inspected. In this embodiment, the transverse lifting unit 2 includes a transverse trolley 21 and a lifting assembly 22. The transverse trolley 21 travels on the upper walking rail 13, and the lifting assembly 22 is installed on the transverse trolley 21 to ensure compatibility.

[0029] The first mobile platform 3 and the second mobile platform 4 are of the same specifications. The first mobile platform 3 and the second mobile platform 4 are respectively suspended on the lower traveling track 12 and located on both sides of the transverse lifting unit 2, providing manual maintenance workstations. Specifically, in this embodiment, as shown... Figure 4 As shown, both the first mobile platform 3 and the second mobile platform 4 include a drive assembly 31, a mobile trolley frame 32, a platform connecting bracket 33, and a platform 34. The drive assembly includes a drive motor and a drive wheel set. Guardrails are provided on the platforms to ensure safety. The mobile trolley frame 32 travels on the lower travel track 12 via the drive assembly 31, and the platform 34 is mounted below the mobile trolley frame 32 via the connecting bracket 33.

[0030] To facilitate maintenance workers' access to the platform and ensure safety, the outermost ends of the first mobile platform 3 and the second mobile platform 4 are moved to the support legs of the portal frame 1, where ladders 7 are installed.

[0031] In other embodiments, the heights of the first and second mobile platforms are adjustable to accommodate the maintenance height requirements of perforation needles or mold assembly tables of different heights.

[0032] Brief description of the work steps: (1) Move the transverse lifting unit 2 directly above the mold assembly table 5. The upper lifting trolley will lift the perforating needle. During this process, the first moving platform 3 and the second moving platform 4 are located at the support legs of the portal frame 1. Figure 1 As shown, this is to prevent the platform from colliding with the assembly table.

[0033] (2) After the worker climbs the ladder to the two moving platforms, he remotely controls the first moving platform 3 and the second moving platform 4 to move simultaneously toward the perforating needle 6, such as Figure 2 As shown.

[0034] (3) Once the position is reached, workers on both sides can simultaneously perform all-around repair and cleaning of the perforating needle 6, such as... Figure 3 As shown, after the maintenance is completed, the mobile platform is retracted to the gantry frame legs, and the upper lifting trolley can then lower the perforating needle vertically.

[0035] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
