Description

Technical Field

[0001] This utility model relates to the field of equipment installation technology, specifically to a crossbeam structure that can be quickly adapted to the longitudinal beam of a crane. Background Technology

[0002] In the field of environmental solid waste disposal, the overhead crane in the incineration line is a key piece of equipment for realizing core operations such as solid waste transfer and feeding. With the increasing demand for intelligent upgrades of the crane, it is necessary to add a vehicle-mounted cabinet on the original crane's longitudinal beam to integrate intelligent equipment such as control and communication. The installation of the vehicle-mounted cabinet relies on the crossbeam structure as a load-bearing foundation.

[0003] In existing technologies, the installation of crossbeams for the longitudinal beams of overhead cranes often adopts the "hole-fixing" method, which involves drilling holes in the longitudinal beam body and then rigidly connecting the crossbeam to the longitudinal beam using bolts. However, this installation method has significant drawbacks in practical applications: Firstly, as the core load-bearing component of the overhead crane, the structural integrity of the longitudinal beam is crucial to the safe operation of the crane. Drilling holes will damage the original mechanical structure of the longitudinal beam, potentially leading to stress concentration, especially under conditions of frequent starts and stops and vibrations, which can easily cause fatigue damage to the longitudinal beam and pose safety hazards. Secondly, drilling requires the use of hot work and drilling equipment on-site, necessitates a special work permit, and requires precise hole positioning to ensure the installation accuracy of the crossbeam. This not only prolongs the construction period but may also lead to problems such as excessive levelness and unstable load-bearing capacity after installation due to hole position deviations, affecting the stable operation of intelligent equipment inside the vehicle cabinet.

[0004] Meanwhile, the environment of environmental solid waste disposal plants is characterized by dust and humidity. If the openings are not properly protected against corrosion, rust can easily occur, further weakening the strength of the longitudinal beam structure. Furthermore, the specifications (such as width and cross-sectional shape) of the longitudinal beams of different crane models vary. Traditionally, crossbeams installed with openings need to be customized for different longitudinal beam specifications, resulting in poor versatility and increasing construction costs and spare parts management difficulties. Therefore, there is an urgent need for a crossbeam installation structure that does not require openings in the longitudinal beams and can adapt to different specifications of longitudinal beams. This would improve installation efficiency and versatility while ensuring the safety of the crane structure, meeting the construction and operation needs of intelligent crane upgrade projects. Utility Model Content

[0005] To address the aforementioned issues, a crossbeam structure that can quickly adapt to the longitudinal beams of a crane is provided. Through the coordinated adjustment of moving and telescopic components, it can adapt to longitudinal beams with different cross-sectional dimensions. The crossbeam, as the main load-bearing component, adopts an insert design at both ends, which cooperates with the sleeves of two connecting components. The sleeves restrict the axial displacement of the crossbeam, enabling rapid assembly of the crossbeam and connecting components. This solves the problem that traditional crossbeams with perforated installations need to be customized for different longitudinal beam specifications, resulting in poor versatility and increased construction costs and spare parts management difficulties.

[0006] To address the problems of existing technologies, this utility model provides a crossbeam structure for rapid adaptation to the longitudinal beam of a trolley, including a connecting assembly for connecting to the longitudinal beam of the trolley and a crossbeam for supporting equipment. The connecting assembly includes a mounting plate, a movable component, a telescopic component, and a sleeve. The movable component is disposed on the mounting plate and can move along the length direction of the mounting plate. The telescopic component is disposed on the mounting plate and can move along the thickness direction of the mounting plate. The movable component can be bolted to the telescopic component. The sleeve is connected to the mounting plate. The connecting assembly can be sleeved on the longitudinal beam of the trolley, and both ends of the crossbeam can be inserted into the sleeves of the two connecting assemblies.

[0007] According to one embodiment of the present invention, a first connecting hole is provided on the mounting plate, and a second connecting hole is provided on the sleeve accordingly. The sleeve is connected to the mounting plate by bolts passing through the first connecting hole and the second connecting hole.

[0008] According to one embodiment of the present invention, the mounting plate is provided with a plurality of adjustment holes, the telescopic member includes a connecting plate and an adjustment bolt, the adjustment bolt is confined in the adjustment holes, and the telescopic member contacts the side wall of the longitudinal beam of the trolley.

[0009] According to one embodiment of the present invention, a sliding groove is provided on one side of the mounting plate, the movable component includes a movable plate and a connecting bolt, one end of the movable plate is restricted to move in the sliding groove, one end of the connecting bolt is movable and restricted on the movable plate and the other end is connected to the connecting plate, and the movable plate contacts one side wall of the trolley longitudinal beam telescopic component.

[0010] According to one embodiment of the present invention, a through hole is provided on one side of the mounting plate, penetrating one side of the top of the slide groove, and a detachable insertion limiting post is provided in the through hole.

[0011] According to one embodiment of the present invention, a receiving plate is welded to one side of the mounting plate, and the top of the receiving plate can contact the bottom of the sleeve.

[0012] According to one embodiment of the present invention, an anti-slip structure is provided on the side of the mounting plate that contacts the longitudinal beam of the trolley.

[0013] According to one embodiment of the present invention, the side of the movable plate that contacts the longitudinal beam of the trolley is provided with an anti-slip structure, and the side of the connecting plate that contacts the longitudinal beam of the trolley is provided with an anti-slip structure.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. The moving and telescopic components are rigidly connected by bolts, forming a bidirectionally adjustable positioning mechanism fitted onto the outside of the longitudinal beam of the main trolley. Adjustment is achieved through the cooperation of the moving and telescopic components to accommodate longitudinal beams of different cross-sectional dimensions. The crossbeam, as the load-bearing body, features an insert design at both ends, engaging with the sleeves of the two connecting components.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1-6As shown, this utility model provides a crossbeam structure for quick adaptation of a trolley longitudinal beam, including a connecting assembly for connecting with the trolley longitudinal beam and a crossbeam for supporting equipment. The connecting assembly includes a mounting plate, a movable component, a telescopic component, and a sleeve. The movable component is mounted on the mounting plate and can move along the length direction of the mounting plate. The telescopic component is mounted on the mounting plate and can move along the thickness direction of the mounting plate. The movable component can be bolted to the telescopic component. The sleeve is connected to the mounting plate. The connecting assembly can be sleeved on the trolley longitudinal beam, and both ends of the crossbeam can be inserted into the sleeves of the two connecting assemblies.

[0025] The moving parts and the telescopic parts are rigidly connected by bolts to form a bidirectional adjustable positioning mechanism. The mounting plate has a U-shaped or groove-shaped structure and can be fitted onto the outside of the longitudinal beam of the trolley. By cooperating and adjusting the moving parts and the telescopic parts, it can adapt to longitudinal beams with different cross-sectional dimensions. The crossbeam, as the main load-bearing component, adopts an insert design at both ends, which cooperates with the sleeves of the two connecting components. The sleeves restrict the axial displacement of the crossbeam, enabling the rapid assembly of the crossbeam and the connecting components.

[0026] The bidirectional adjustment of the moving and telescopic components allows for the coverage of longitudinal beams of different specifications (width, height) within a certain range, eliminating the need for customized structures for specific longitudinal beams and reducing spare parts management costs. The use of nested assembly and plug-in connections avoids traditional welding or complex splicing processes; on-site adjustment and fixing are completed simply with bolts, shortening the installation cycle and meeting the efficiency requirements of intelligent crane retrofit projects. The components feature a modular design, with lightweight individual parts (such as mounting plates and moving parts, which can be made from thin steel plates through stamping), facilitating on-site handling and high-altitude operations, thus reducing labor intensity during construction.

[0027] The mounting plate has a first connecting hole, and the sleeve has a corresponding second connecting hole. The sleeve is connected to the mounting plate by bolts passing through the first and second connecting holes. Figure 3 As shown, the sleeve and the mounting plate are detachably connected by bolts. One end of the bolt protrudes into the sleeve. When the end of the crossbeam extends into the sleeve, it can be blocked from moving by the end of the bolt. Preferably, the outer wall of the end of the crossbeam contacts the inner wall of the sleeve, or further, the sleeve can be inserted into the end of the crossbeam. At this time, the connection between the sleeve and the mounting plate plays the role of restricting the movement of the crossbeam.

[0028] The mounting plate has several adjustment holes. The telescopic component includes a connecting plate and adjusting bolts. The adjusting bolts are confined within the adjustment holes, and the telescopic component contacts the side wall of the longitudinal beam of the trolley. For example... Figures 3-6As shown, the telescopic component can move along the thickness direction of the mounting plate, which can limit the longitudinal beams of the trolley with different thicknesses. Preferably, the connecting plate of the telescopic component contacts the side wall of the longitudinal beam of the trolley, and the side of the connecting plate in contact with the longitudinal beam of the trolley is provided with an anti-slip structure. This can reduce the relative sliding between the telescopic component and the longitudinal beam of the trolley under driving vibration and start-stop impact conditions, which would cause the crossbeam to shift and thus affect the stability of the installation of the vehicle-mounted cabinet equipment.

[0029] A groove is provided on one side of the mounting plate. The moving part includes a moving plate and a connecting bolt. One end of the moving plate is restricted to move within the groove, and one end of the connecting bolt is movable and restricted to the moving plate, while the other end is connected to the connecting plate. The moving plate contacts one side wall of the trolley longitudinal beam's telescopic component. Preferably, an anti-slip structure is provided on the side of the moving plate that contacts the trolley longitudinal beam. The moving plate can move within the groove, and by tightening the connecting bolt on the connecting plate, the moving plate gradually presses against the side wall of the trolley longitudinal beam, thereby ensuring close contact between the moving part and the trolley longitudinal beam.

[0030] A through hole extending through the top of the slide groove is provided on one side of the mounting plate, into which a detachable limiting post can be inserted. A receiving plate is welded to one side of the mounting plate, the top of which contacts the bottom of the sleeve. An anti-slip structure is provided on the side of the mounting plate that contacts the longitudinal beam of the trolley. Figures 3-6 As shown, a through hole is provided on one side of the mounting plate. By inserting limiting posts of different thicknesses into the through hole, the limiting posts can compress the end of the moving plate and restrict it in the slide groove, making the moving plate tightly fit against the side wall of the trolley longitudinal beam. Since the end of the moving plate away from the slide groove is connected to a connecting bolt, the end of the moving plate with the connecting bolt is tightly fitted against the trolley longitudinal beam. Adding limiting posts can further increase the tight contact between the moving plate and the trolley longitudinal beam. The receiving plate is used to support the sleeve. Preferably, the second connecting hole allows the sleeve to slide vertically on the mounting plate, that is, the receiving plate can bear the weight transmitted from the crossbeam to the sleeve.

[0031] It should be noted that, in order to prevent metal parts from being directly exposed to the dust and humid environment of the environmentally friendly plant area, which could lead to electrochemical corrosion, all metal parts undergo surface anti-corrosion treatment, such as hot-dip galvanizing (film thickness ≥80μm) followed by spraying epoxy primer + polyurethane topcoat to improve salt spray resistance. Dustproof sealing rings (such as lip seals) are installed at the sliding gaps between moving parts and mounting plates to prevent dust from entering and affecting the adjustment function. Thread locking adhesive is applied to bolted connections to resist rust in humid environments.

[0032] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
