Description

Technical Field

[0001] This utility model belongs to the field of suspended conveying, and specifically relates to a flexible safety roller shutter for the entrance and exit of a hoist conveyor vehicle. Background Technology

[0002] In overhead conveyor or rail-guided trolley conveyor systems, the conveyor needs to carry the product along the track; however, the track is always located at the edge of the elevator and passes through the elevator's inlet and outlet, with the conveyor carrying the product entering and exiting the elevator via the track.

[0003] Although other parts of the elevator are equipped with safety nets, the elevator's inlet and outlet are open. The size of the opening is determined by the conveyor vehicle, the mounting brackets, and the products. The opening is usually quite large, posing a significant safety hazard, as people or objects can easily fall into the elevator through this opening.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a flexible safety roller shutter for the entrance and exit of the elevator conveyor vehicle, which provides flexible protection for suspended transportation; when the several blocking bars are lowered, they stack without affecting the transportation on the track, and when the several blocking bars are raised, they provide protection for the elevator to lift materials, while avoiding the tracks at the elevator entrance and exit. The structure is simple, the design is reasonable, the cost is very low, and it is very practical.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a flexible safety roller shutter for the entrance and exit of a hoisting conveyor vehicle, comprising a set of guide rods, several blocking rods, a set of wire ropes, and a winch; the guide rods are arranged opposite each other; the guide rods have axially spaced limiting tracks; slots for the limiting tracks are formed on opposite sides of the guide rods; the blocking rods are positioned between the guide rods; both ends of the blocking rods are located within the limiting tracks on both sides and are positioned by the slots; the portions of the blocking rods located within the limiting tracks at both ends are provided with rope-passing holes; the wire ropes are located within the limiting tracks and pass through the rope-passing holes of several blocking rods in sequence; the wire ropes are connected to the blocking rods, thus achieving connection between the several blocking rods; the winch is located above the guide rods, and its output end is connected to the wire ropes. Limiting rails are installed on the guide rods, providing stable guidance for the raising and lowering of the blocking rods. Furthermore, the stacking of the blocking rods after they are lowered does not affect the transport along the rails. When several blocking rods are raised, they form a protective barrier similar to a roller shutter, improving the safety of the elevator when lifting materials. The wire rope has high strength and durability, can withstand significant tensile force, and is not easily broken. The output end of the winch is connected to the wire rope, enabling precise control of the raising and lowering of several blocking rods, preventing jamming or malfunctions during operation, and ensuring stable system operation.

[0007] Furthermore, it also includes a set of fixed pulleys; the fixed pulleys are located directly above the guide rod, and the wire rope passes through the fixed pulleys and connects to the output end of the winch. The fixed pulleys change the direction of force transmission of the winch, realizing the turning of the wire rope and facilitating the arrangement of the winch.

[0008] Furthermore, the blocking rod is provided with limiting plates at both ends; the limiting plates are located within the limiting track. The blocking rod moves along the limiting track via the limiting plates, thereby enabling the flexible safety roller shutter to be raised and lowered.

[0009] Furthermore, the width of the slot is slightly smaller than the width of the limiting piece, ensuring that the blocking rod can be limited by the limiting piece in conjunction with the slot, preventing axial movement of the blocking rod and ensuring its stability.

[0010] Furthermore, it also includes a kick plate; the kick plate is located between the bottom of the guide rods. The presence of the kick plate can reduce the probability of personnel or equipment colliding with the bottom of the guide rods during movement, playing a certain role in buffering and warning, thereby improving the safety of the working environment.

[0011] Furthermore, the distance between each pair of blocking bars is equal. This equal spacing between the blocking bars ensures more stable protection when the flexible safety roller shutter is raised.

[0012] Furthermore, the bottom of the guide rod is also equipped with foot pads. The foot pads distribute the pressure on the guide rod and provide it with a more stable support surface.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: This utility model discloses a flexible safety roller shutter for the entrance and exit of a hoist conveyor vehicle, providing flexible and adaptable protection for suspended transportation; when several blocking bars are lowered, they stack without affecting the transportation on the track, and when several blocking bars are raised, they provide protection for the hoist to lift materials, while avoiding the tracks at the hoist's inlet and outlet. The structure is simple, the design is reasonable, the cost is very low, and it is very practical. Attached Figure Description

[0017] Specifically, the winch 4 controls the raising and lowering of the wire rope 3, thereby raising and lowering the blocking rod 2, so that several blocking rods 2 form a curtain-like protection.

[0018] Specifically, first determine the size of the opening width of the external hoist protective net, and then determine the length of the blocking rod 2; the length of the blocking rod 2 must be longer than the opening width of the hoist protective net.

[0019] Specifically, the raising and lowering of the blocking rod 2 can be controlled by controlling the number of turns of the winch 4 or by installing a sensor on the limit rail 11.

[0020] Specifically, winch 4 can be replaced with a combination of a small motor and pulleys as an option to power the winding or unwinding of the wire rope.

[0021] In this embodiment, as Figure 1 It also includes a set of fixed pulleys 5; the fixed pulleys 5 are located directly above the guide rod 1, and the wire rope 3 passes through the fixed pulleys 5 and is connected to the output end of the winch 4.

[0023] In this embodiment, as Figures 1 to 3 The blocking rod 2 has limiting pieces 22 at both ends; the limiting pieces 22 are located inside the limiting track 11.

[0024] Specifically, circular pieces are preferred for the limiting piece 22.

[0025] In this embodiment, as Figure 2 The width of the slot 12 is slightly smaller than the width of the limiting piece 22.

[0026] Specifically, a thin shim can be added to the inside of the slot 12 as an option to prevent the fit between the slot 12 and the limiting piece 22 from being too loose.

[0027] In this embodiment, as Figure 1 It also includes a kick plate 6; the kick plate 6 is located between the bottoms of the guide rods 1.
