Description

Technical Field

[0001] This application relates to the field of cable conveying equipment technology, and specifically to a lightweight cable conveyor. Background Technology

[0002] In the cable conveying stage of cable construction, conveyors are often needed to provide stable and continuous traction to overcome the cable's own weight and frictional resistance, ensuring construction efficiency and safety. Currently, most widely used cable conveyors employ a modular, spliced, or on-site welded assembly frame structure. This design results in a complex overall structure and numerous components. The direct consequence is that the equipment itself is heavy and bulky; while rigidity is guaranteed, portability and flexibility are severely lacking.

[0003] In construction sites requiring frequent relocation (such as long-distance cable laying and multi-point construction) or with limited space (such as tunnels, pipe corridors, equipment mezzanines, and indoor renovations), the handling and relocation of existing cable conveying equipment is extremely inconvenient, time-consuming, and labor-intensive. It often requires the use of large machinery such as cranes or the coordinated operation of multiple people, significantly increasing construction preparation time, labor costs, and equipment rental expenses. Furthermore, the heavy equipment is difficult to operate in confined spaces, posing a risk of collision damage or cable abrasion, which also limits its application in complex terrain and small work areas.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] In view of at least one of the above technical problems, this application discloses a lightweight cable conveyor, which aims to solve the technical problems of existing cable conveyors being complex in structure, large in size and difficult to handle.

[0006] According to one aspect of this disclosure, a lightweight cable conveyor is provided, comprising an integrated frame with multiple functional mounting positions, two conveying components forming a conveying channel between them, a clamping component fixed to the corresponding mounting positions and used to adjust the position of the two conveying components to adjust the width of the conveying channel, a conveying drive unit drivenly connected to the conveying components and symmetrically fitted to the corresponding mounting positions about the center of the conveying channel, guide roller assemblies fixed to the corresponding mounting positions at both ends of the integrated frame and located at the inlet and outlet of the conveying channel, an electrical control unit fixed to the corresponding side mounting position of the integrated frame, and lifting rings fixed to the bottom of the integrated frame for handling and fixing the conveyor.

[0007] In some embodiments of this disclosure, the mounting position includes clamping assembly mounting portions symmetrically arranged on the front and rear sides of the integrated frame, guide roller brackets symmetrically arranged on the left and right ends of the integrated frame for mounting the guide roller assembly, a drive fitting portion opened on the integrated frame for matching the transmission drive unit, and a control window opened on one side of the integrated frame for cooperating with the electrical control unit.

[0008] In some embodiments of this disclosure, the clamping assembly includes a positive and negative lead screw rotatably mounted on the clamping assembly mounting portion, a lead screw nut correspondingly engaged with the positive and negative lead screws on the opposite threaded sections, at least four guide rail posts fixed on the clamping assembly mounting portion and located on both sides of the positive and negative lead screws, and a clamping platform correspondingly fixed on the lead screw nut and slidably sleeved with the guide rail posts to move in opposite directions or in opposite directions along the direction of the guide rail posts.

[0009] In some embodiments of this disclosure, the guide roller bracket includes symmetrically arranged side plates, a plurality of fixing holes vertically opened on the side plates, a crossbeam fixed between the two side plates, and fasteners fixed on the crossbeam and cooperating with adjacent guide rail columns.

[0010] In some embodiments of this disclosure, the guide roller assembly includes at least two sets of guide rollers fixed to the side plate through fixing holes.

[0011] In some embodiments of this disclosure, the conveying assembly includes a drive sprocket assembly rotatably mounted on a clamping platform and connected to the drive shaft of a corresponding conveying drive unit, a passive sprocket assembly driven by a track and connected to the drive sprocket assembly, and a reinforcing support assembly fixed on the clamping platform and located between the drive sprocket assembly and the passive sprocket assembly.

[0012] In some embodiments of this disclosure, the support assembly includes an independent bracket disposed on the inner side of the track and a support plate fixed on the independent bracket and correspondingly in contact with the track.

[0013] One or more technical solutions provided in the embodiments of this application have at least one of the following technical effects or advantages: This application's technical solution adopts a lightweight design with an integrated frame incorporating multiple functional mounting positions. Compared to the steel structure welding of existing conveyors, this achieves significant weight reduction. By setting guide roller supports on the integrated frame and locking them with fasteners to nearby guide rail columns, the rigidity and stability of the overall frame are improved. The lifting rings on the integrated frame facilitate handling and securing, making it suitable for construction relocation requiring frequent site visits, improving construction mobility and efficiency, and reducing handling costs and difficulties. Simultaneously, the symmetrically arranged front and rear conveyor drive units and their embedded installation structure within the integrated frame, along with the rational installation and distribution of other components within the integrated frame, integrate all functional components with the integrated frame, reducing the overall size of the conveyor and avoiding additional space occupation.

[0021] Unless otherwise specified, the unit modules, components, structures, mechanisms, or sensors involved in the following embodiments are all commercially available products.

[0022] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] To address the technical problems of existing cable conveyors, such as their bulkiness and difficulty in handling, this embodiment discloses a lightweight cable conveyor, such as... Figure 1 , 2 As shown, an integrated frame 1, comprising multiple functional mounting positions, serves as the skeleton and foundation of the entire conveyor. Preferably, the integrated frame 1 includes a frame body 2 made of aluminum alloy through integral casting, which reduces weight by two-thirds compared to existing welded steel structures, resulting in lower cost, higher precision, and greater strength. To facilitate the installation of each functional component, the mounting positions include clamping assembly mounting parts symmetrically located on the front and rear sides of the integrated frame 1, guide roller supports symmetrically located on the left and right ends of the integrated frame for mounting the guide roller assemblies, a drive fitting part 4 on the integrated frame 1 for matching the conveying drive unit, and a control window 5 on one side of the integrated frame 1 for cooperating with the electrical control unit. To adapt the mounting parts on the integrated frame 1 to the clamping assembly mounting, it includes a connecting part 6 located at the center of the frame body 2 and connecting parts 7 symmetrically located on both sides of the connecting part 6. This highly integrated design uses a symmetrical structure to rationally distribute the mounting positions of each functional component, reducing equipment weight and construction space requirements, making it suitable for space-constrained construction environments. Furthermore, a lifting ring 3 is fixed to the bottom left or right side of the frame body 2. The lifting ring 3 provides a convenient and reliable lifting and fixing pad for the entire conveyor. Combined with the lifting ring 3, the equipment can be quickly moved and installed using tools such as slings.

[0024] To achieve cable clamping functionality on the integrated frame 1, such as Figure 1 , 3As shown, a clamping assembly 8 is fixed on the integrated frame 1, which includes a positive and negative lead screw 9 rotatably mounted on the connecting part 1 6 and four guide rail posts 10 fixedly mounted on the connecting part 2 7. Lead screw nuts 11 are respectively fitted on the opposite threaded sections of the positive and negative lead screw 9. A clamping platform 12 is fixed on the lead screw nut 11 and simultaneously slides with the guide rail posts 10. Preferably, the clamping platform 12 slides with the guide rail posts 10 through a guide tube 13 at its bottom. The lead screw nut fixing piece 14 and the lead screw nut 11, along with the four guide rail posts 10, ensure stable operation of the conveyor during construction and prevent the conveying assembly 15 from swaying up and down. Specifically, when the positive and negative lead screws are driven to rotate by a handwheel or a small motor, the two lead screw nuts 11 will move synchronously towards or away from each other along the guide rail posts 10 due to their opposite threaded directions, thereby driving the clamping platform fixed on it to move precisely and synchronously.

[0025] In order to achieve the transmission of cables, such as Figure 1 , 4As shown in Figure 5, two conveying components 15 are respectively provided on the two clamping platforms 12, forming a conveying channel between the two conveying components 15. The width of the conveying channel can be synchronously adjusted under the drive of the clamping components 8. The two conveying components 15 are respectively connected to a conveying drive unit 16 that is symmetrically fitted into the drive fitting part 4 about the center of the conveying channel. The arrangement of the conveying drive unit 16 greatly shortens the length of the conveyor, significantly reducing the weight of the equipment and the labor intensity of the workers. Preferably, the conveying drive unit 16 includes a worm gear reducer 17 and a drive motor 18 connected to the worm gear reducer 17. The worm gear reducer 17 and the drive motor 18 are fixed on the clamping platform 12 by a mounting bracket 19 provided at the bottom of the clamping platform 12. Further, the conveying assembly 15 includes a driving sprocket assembly 20 and a driven sprocket assembly 21 rotatably mounted on the clamping platform 12. Preferably, both the driving sprocket assembly 20 and the driven sprocket assembly 21 include a rotating shaft and sprockets relatively fixed on the rotating shaft. The rotating shaft of the driving sprocket assembly 20 is connected to the rotating shaft of a worm gear reducer via a coupling, and the sprockets of the driven sprocket assembly 21 are connected to the sprockets of the driving sprocket assembly 20 via a track 22. Preferably, the track 22 is a mini track suitable for lightweight cable conveyors, and the rotating shaft of the driven sprocket 21 is provided with an adjustable push rod for adjusting and maintaining appropriate tension of the track 22. To overcome the sagging and vibration problems that may occur when the track 22 is subjected to pressure over a long span, a support assembly is fixedly installed on the clamping platform 12 between the driving sprocket assembly 20 and the driven sprocket assembly 21, and a protective cover is provided on the outside of the conveying assembly 15. Furthermore, the support assembly includes two independent brackets 23 standing on the inner side of the track 22 and a support plate 24 fixed on the two independent brackets 23 and in contact with the inner side of the track 22, which effectively prevents track deformation and vibration and ensures stable and reliable traction when delivering cables.

[0026] For safe, low-resistance, and precise cable guiding, such as Figure 1 , 2As shown, a guide roller assembly 25 consisting of two sets of guide rollers is installed on the guide roller bracket of the integrated frame 1. Further, the guide roller bracket includes two symmetrically arranged side plates 26 and a crossbeam 27 fixedly connected between the two side plates 26. To facilitate the adjustable height installation of the guide rollers 25 on the side plates 26, several fixing holes 28 of different heights are correspondingly provided on the two side plates 26. To enhance the rigidity and stability of the guide roller bracket and prevent bending, fasteners 29 are fixed on the crossbeam 27 and locked to the adjacent guide rail columns 10, so that the pressure on the side plates 26 during operation is transmitted to the entire frame structure, extending the service life of the guide roller bracket. To control the use of various functional units of the conveyor, an electrical control unit 30 is fixed inside the control window 5 of the integrated frame 1. The electrical control unit 30 is also equipped with an overload alarm to ensure construction safety and convenient operation.
