Detailed Implementation
[0015] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.
[0016] like Figures 1-5 The illustrated belt conveyor protection device includes a conveyor belt 1 and two sets of protective mechanisms disposed on the upper part of the conveyor belt 1. The two sets of protective mechanisms are detachably disposed on both sides of the upper part of the support frame 2 of the conveyor belt 1. The conveyor belt 1 can adopt an existing conveyor belt structure, with supports 2 at both ends. The lower part of the supports 2 is supported by feet. Other structural details are not elaborated upon.
[0017] The protective mechanism includes a protective sleeve 3, a height adjustment device, and a protective plate 4. The protective sleeve 3 is a rectangular parallelepiped extending through the top, with a length and width equal to the length and width of the support 2. The bottom of the protective sleeve 3 is detachably connected to the support 2. Specifically, the bottom of the protective sleeve 3 has a through hole, and the protective sleeve 3 is fixed to the upper part of the support 2 by a bolt assembly consisting of a bolt and a nut passing through the through hole and the support 2. The protective plate 4 is slidably disposed inside the protective sleeve 3, and the size of the protective plate 4 is the same as the internal size of the protective sleeve 3. The protective sleeve 3 and the protective plate 4 are connected by the height adjustment device, which is used to adjust the height of the protective plate 4.
[0018] By incorporating a height adjustment device, operators can flexibly adjust the height of the protective plate 4 according to actual conditions, adapting it to the diverse protection needs of operators of different heights and materials of varying heights. For example, when taller operators are working, the protective plate 4 can be raised to ensure their entire body is within the safe protection range; when conveying taller materials, the height of the protective plate 4 can also be adjusted accordingly to prevent accidental tipping or splashing of materials from injuring operators. This not only enhances the versatility and practicality of the protective device but also maximizes the personal safety of operators, reduces the risk of accidents caused by inadequate protection, and provides a reliable barrier for the safe operation of belt conveyors.
[0019] Furthermore, the bottom of the protective plate 4 is provided with a support column 11, the bottom of which is connected to the upper part of the support spring 12, and the bottom of the support spring 12 is connected to the inner bottom of the protective sleeve 3. The support spring 12 supports the bottom of the protective plate 4.
[0020] Furthermore, both the protective sleeve 3 and the protective plate 4 have U-shaped stop bars 13 on their sidewalls away from the conveyor belt 1. The two ends of the stop bars 13 are connected to the sidewalls of the protective sleeve 3 and the protective plate 4. The stop bars 13 can be fixed to the protective sleeve 3 and the protective plate 4 with bolts for easy disassembly and adjustment; alternatively, the stop bars 13 can be directly welded to the protective sleeve 3 and the protective plate 4 to enhance the connection's strength. Specifically, the stop bars 13 on the protective sleeve 3 are located in the middle of its sidewall, and the stop bars 13 on the protective plate 4 are located in the upper part of its sidewall. Furthermore, the middle of the stop bars 13 is provided with several reinforcing rods 14 to increase the stability of the stop bars 13, and the ends of the reinforcing rods 14 are connected to the protective sleeve 3 and the protective plate 4. The stop bars 13 ensure a safe distance between the operator and the conveyor belt 1, effectively preventing clothing, hair, or other personal belongings from being caught in the gap between the conveyor belt 1 and the rollers due to accidental close proximity during operation.
[0021] Example 1 like Figure 2 As shown, in this embodiment, the height adjustment device includes a first driving member 5, a first screw 6 arranged in parallel, and two guide rods 7; The bottom of the first screw 6 is rotatably connected to the inner bottom of the protective sleeve 3, specifically through a bearing. The upper part passes through the protective plate 4 and is threadedly connected to the protective plate 4. Its top is coaxially connected to the first driving member 5. The two guide rods 7 are respectively arranged on both sides of the first screw 6. The bottom is connected to the inner bottom of the protective sleeve 3, and the upper part passes through the protective plate 4 and is slidably connected to the protective plate 4, thus playing a guiding role.
[0022] In this embodiment, two guide rods 7 are symmetrically arranged on both sides of the first screw 6; the first driving component 5 includes a hand crank or a motor. When it is a motor, the output shaft of the motor is coaxially connected to the first screw 6 through a coupling.
[0023] Additionally, the upper part of the first screw 6 and the guide rod 7 are both provided with limiting plates 15 to limit the height of the movement of the protective plate 4.
[0024] Example 2 This embodiment is a further optimization based on Embodiment 1 and is suitable for larger belt conveyors. In this embodiment, the first drive component 5 includes a motor. The height adjustment device also includes a second screw 8 with the same pitch as the first screw 6. The bottom of the second screw 8 is rotatably connected to the inner bottom of the protective sleeve 3, and the upper part passes through the protective plate 4 and is threadedly connected to the protective plate 4. The first screw 6, the second screw 8, and the two guide rods 7 are symmetrically arranged on both sides of the middle part of the bracket 2 to evenly distribute the load.
[0025] In one possible implementation, the top of the second screw 8 is coaxially connected to a second driving component 9, which is a motor of the same model as the first driving component 5. During use, both output the same speed, thus ensuring that the two screws rotate at the same speed, preventing the protective plate 4 from jamming or damaging the threaded pair. Figure 3 and Figure 4 As shown.
[0026] In another possible implementation, the upper part of the second screw 8 is connected to the upper part of the first screw 6 via a transmission assembly 10. The transmission assembly 10 includes a belt or chain. When it is a chain, the upper parts of the two screws are provided with sprockets of the same size, and the chains are connected to the outside of the sprockets. Figure 5 As shown. In this embodiment, the transmission assembly 10 is located between the limiting plate 15 and the driving member.
