A box turning machine overhead rail maintenance platform

Abstract

This application discloses a maintenance platform for a box-turning machine's overhead track, relating to the field of tobacco machinery technology. The platform achieves bidirectional locking through support components. Its rectangular frame has a first-shaped locking element and a second-shaped locking element at its bottom, with their constraint directions perpendicular. The first-shaped locking element engages with the hopper, limiting platform displacement along the overhead track's extension direction; the second-shaped locking element engages with the lifting frame, limiting displacement perpendicular to the overhead track. A guardrail is detachably installed on the side of the frame away from the lifting frame; a support plate is fixedly covering the top surface of the frame to form a working plane. This design creates rigid support between the hopper and the lifting frame, eliminating the risk of maintenance personnel falling while straddling, and simultaneously providing safety rope attachment points and tool storage space, systematically solving the safety hazards of high-altitude maintenance.

Description

Technical Field

[0001] This application relates to the field of tobacco machinery technology, and in particular to a maintenance platform for a box-turning machine's overhead rail. Background Technology

[0002] In the tobacco processing stage, the box-turning machine in the vertical storage section is a key piece of equipment, undertaking the core tasks of tobacco box transfer, tobacco dumping, and empty box recycling. The overhead track system, as the core support and guiding component of the box-turning machine, is prone to problems such as track deformation and roller wear during long-term operation, requiring regular high-altitude inspection and maintenance. Currently, to improve equipment efficiency, the industry generally modifies the top gate of the box-turning machine into a funnel-shaped hopper structure. While this significantly reduces the failure rate and shortens the box-turning cycle, this hollow design completely eliminates the original planar support structure on top of the equipment.

[0003] When the modified box tipper is being inspected along the overhead rail, maintenance personnel are forced to stand on the narrow edge of the wall adjacent to the hopper, resulting in a severe lack of effective foothold. This working method leaves the personnel's center of gravity suspended in mid-air, with no reliable anchor points for safety ropes and no secure place to put tools, significantly increasing the risk of falls from heights and injuries from falling tools. This has become a prominent bottleneck restricting the safety of equipment maintenance.

[0004] Therefore, this application proposes a overhead track maintenance platform for a box-turning machine, which can reconstruct the high-altitude operation support system and systematically solve the dual safety hazards of personnel falling and tools falling while ensuring maintenance efficiency. Utility Model Content

[0005] The main purpose of this application is to provide a maintenance platform for the overhead rail of a box-turning machine, which aims to solve the technical problem of insufficient effective foothold area during overhead rail maintenance.

[0006] To achieve the above objectives, this application provides the following technical solution: A maintenance platform for a box-turning machine's overhead rail, the box-turning machine comprising a horizontally arranged overhead rail, a lifting frame suspended on the overhead rail, and a hopper located on one side of the lifting frame; the maintenance platform includes: The support assembly includes a rectangular frame, and a first and a second shaped locking member located at the bottom of the frame and whose constraint directions are perpendicular to each other in the horizontal plane; the first shaped locking member is engaged with the hopper to restrict the platform from moving along the extension direction of the overhead track; the second shaped locking member is engaged with the lifting frame to restrict the platform from moving along the direction perpendicular to the extension direction of the overhead track. The guardrail is installed on the frame via a detachable structure and is located away from the lifting frame; A support plate is fixedly attached to the top surface of the frame.

[0007] As a further improvement of this application, both the first and second locking components are U-shaped locking forks with downward openings, and their constraint directions in the horizontal plane form an angle of 90°±2°.

[0008] As a further improvement of this application, the detachable structure includes: at least two insert rods located at the bottom of the guardrail, and at least two sleeves located on the frame, each sleeve being adapted to fit one insert rod and forming a clearance fit.

[0010] As a further improvement to this application, both the frame and the guardrail are welded from stainless steel square tubing.

[0011] The technical solution provided in this application may include the following beneficial effects: During use, this application constructs a stable support plane between the hopper of the box tipper and the elevator frame through the bidirectional vertical constraint structure of the first and second locking parts, completely eliminating the risk of falls for maintenance personnel working in a straddle position, and providing reliable attachment points for safety ropes and space for tool placement, thus systematically solving the safety hazards of high-altitude maintenance.

[0021] Figure 1 This application illustrates an embodiment of a top rail maintenance platform for a box-turning machine. In this embodiment, the box-turning machine includes a horizontally arranged top rail 100, a lifting frame 200 suspended on the top rail 100, and a hopper 300 located on one side of the lifting frame 200. The maintenance platform includes a support assembly 1, a guardrail 2, and a support plate 3.

[0022] Specifically, see Figure 1 The support component 1 includes a rectangular frame 11, and a first shaped locking member 12 and a second shaped locking member 13 located at the bottom of the frame 11 and perpendicular to each other in the horizontal plane. The first shaped locking member 12 is engaged with the outside of the hopper 300, restricting the displacement of the platform along the extension direction of the overhead rail 100. The second shaped locking member 13 is engaged with the lifting frame 200, restricting the displacement of the platform along the extension direction of the vertical overhead rail 100. The guardrail 2 is installed on the frame 11 through a detachable structure 4 and is located away from the lifting frame 200. The support plate 3 is fixedly covered on the top surface of the frame 11. Through the bidirectional vertical constraint structure of the first shaped locking member 12 and the second shaped locking member 13, a stable support plane is constructed between the hopper 300 of the tipper and the lifting frame 200, completely eliminating the risk of falls for maintenance personnel working in a straddle position, and providing reliable attachment points for safety ropes and space for tool placement, systematically solving the safety hazards of high-altitude maintenance.

[0023] It should be noted that, as Figure 2As shown, the lifting frame 200 is provided with a crossbar parallel to the extension direction of the overhead rail 100. The opening of the hopper 300 is a rectangular structure and has a side perpendicular to the crossbar in the horizontal plane. The first locking member 12 is engaged with the side of the opening of the hopper 300 perpendicular to the extension direction of the crossbar, and the second locking member is engaged with the crossbar. The two work together to create a stable support plane between the hopper 300 of the box-turning machine and the lifting frame 200.

[0024] Further, see Figure 3 Both the first locking member 12 and the second locking member 13 are U-shaped locking forks with downward openings. The axes of their openings are perpendicular to each other. The opening of the first locking member 12 is adapted to the side wall of the opening of the hopper 300, and the second locking member 13 is adapted to the width of the crossbar, so that the frame 11 is stable between the lifting frame 200 and the hopper 300.

[0025] Optionally, the first locking member 12 and the second locking member 13 form an angle of 90°±2° in the constraint direction in the horizontal plane.

[0026] Optionally, the spacing between the inner walls of the opening of the first locking member 12 is equal to the thickness of the side wall of the hopper 300 opening plus (0.5~1) mm, so as to ensure that the first locking member 12 clamps the side wall of the hopper 300 opening without shaking.

[0027] Optionally, the spacing between the inner walls of the opening of the second locking member 13 is equal to the width of the crossbar of the lifting frame 200 + (0.5~1) mm, so as to ensure that the second locking member 13 clamps the crossbar of the lifting frame 200 without shaking.

[0028] Further, see Figure 4 The detachable mechanism includes at least two insert rods 41 located at the bottom of the guardrail 2 and at least two sleeves 42 located on the frame 11. Each insert rod 41 is adapted to and inserted into each sleeve 42 so that the guardrail 2 is vertically mounted on the frame 11.

[0029] Optionally, the gap between the inner wall of the sleeve 42 and the side wall of the insertion rod 41 is 0.5 to 1 mm.

[0030] Optionally, in this embodiment, the best embodiment is to provide two insert rods 41 at the bottom of the guardrail 2 and two sleeves 42 at the top of the frame 11 on the side away from the lifting frame.

[0031] Optionally, the support plate 3 includes a base layer and a surface layer. The base layer is made of aluminum alloy, and the surface layer is made of wear-resistant engineering plastic and has anti-slip textures with a depth of ≥1mm.

[0032] Optionally, a D-shaped ring (breaking strength 22kN) is provided at the top of guardrail 2 to allow the safety rope to be used at a high altitude.

[0033] Optionally, both the frame 11 and the guardrail 2 are welded from stainless steel square tubing.

[0034] For example, frame 11 and guardrail 2 are both made of 40mm×40mm stainless steel square tubes by cutting and welding, insert rod 41 is made of 38mm×38mm stainless steel square tubes, sleeve 42 is made of 40mm×40mm stainless steel square tubes, and the wall thickness is 1~0.5mm.

[0035] In this embodiment, the support system for high-altitude maintenance operations is completely reconstructed through the systematic integration of a bidirectional orthogonal mechanical locking structure and modular safety components. Support component 1 employs two sets of U-shaped locking forks at a 90° angle, precisely engaging the vertical folded edge of the hopper 300 and the crossbar of the lifting frame 200, forming full constraint on horizontal displacement. This creates a stable working plane between the equipment bodies, effectively preventing the risk of personnel's center of gravity being suspended when straddling the edge of the hopper 300. The guardrail 2 system achieves modular installation through the quick-connection of tapered inserts 41 and sleeves 42. A high-strength D-ring is integrated at the top as a reliable attachment point for the safety rope. Simultaneously, a folding tool table interface is reserved in the middle of guardrail 2, significantly reducing the risk of tools falling. The anti-slip support plate 3 uses an aluminum alloy matrix with a composite engineering plastic surface, and laser-engraved deep textures enhance wet grip, ensuring the stability of personnel movements.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
