Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor belt maintenance, in particular to a special protective shed for belt conveyor belt vulcanization operation. Background Art

[0002] A conveyor belt is an annular structure made of composite materials such as rubber, fiber and metal. It is tightly wound around the drum of the belt conveyor and is driven by the drum to achieve continuous conveying of materials. During the installation, maintenance or replacement of the conveyor belt, rubber vulcanization is often required to ensure the connection strength and operational reliability of the conveyor belt. Vulcanization is a process with extremely high environmental requirements. It is necessary to avoid dust pollution, maintain appropriate temperature and humidity, and strictly prevent water vapor from entering the vulcanization area to avoid quality problems such as bulging and debonding at the vulcanized joints. In addition, since the vulcanization operation takes a long time, usually 4-6 hours, the ambient temperature in the vulcanization area must be kept stable to prevent vulcanization defects caused by temperature changes.

[0003] At present, the on-site vulcanization operation process of large belt conveyors has the following major problems: 1. The frame height of large belt conveyors is generally high, generally above 6 meters, and some are even as high as 30 meters, and often have a certain inclination angle. When performing vulcanization operations on elevated belt conveyors, maintenance personnel face a complex working environment and lack suitable safety belt hanging points, which poses a risk of falling from height. During nighttime emergency repairs, the on-site environment is complex, personnel are concentrated, lighting conditions are poor, and vision is limited, further increasing the safety hazards of the operation; 2. The on-site operating environment is harsh, especially under adverse weather conditions such as windy, rainy, etc., dust and water vapor cannot avoid interfering with the vulcanization operation, resulting in the vulcanization joint being easily contaminated, affecting the vulcanization quality. In addition, the vulcanization operation is highly sensitive to temperature and humidity. Uncontrollable factors in the on-site environment can easily lead to vulcanization defects such as bulging and debonding, thereby affecting the operating performance and life of the conveyor belt; 3. The size of the generally erected protective shed is fixed and cannot be adapted to different types of belt conveyors. Therefore, a special protective shed for vulcanization operations of belt conveyor belts is proposed. Utility Model Content

When performing vulcanization operations on elevated belt conveyors, maintenance personnel face a complex working environment, lack of suitable safety belt hanging points, and the risk of falling from heights.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Reference Figures 1-6 A protective shed includes multiple support mechanisms. Each support mechanism is composed of two crossbeams 1, each of which is fixedly connected to a connecting rod 3 on one side of the bottom of the crossbeam 1. An outer sleeve 2 is slidingly sleeved on the outside of the connecting rod 3. The bottom of the outer sleeve 2 is rotatably connected to the support rod 5 via a rotating shaft 1 4, allowing flexible adjustment of the structure. In addition, a threaded rod 14 is fixedly connected to the top of the rotating shaft 1 4. The threaded rod 14 passes through the bottom of the outer sleeve 2 and is threadedly connected to the bottom of the connecting rod 3. This design allows the height of the connecting rod 3 to be adjusted by rotating the threaded rod 14.

[0026] To ensure a stable connection between the outer sleeve 2 and the connecting rod 3 after height adjustment, the present invention incorporates a fixing mechanism. This fixing mechanism includes a main body 6, which is fixedly mounted on the outer wall of the outer sleeve 2. Multiple mounting slots 7 are defined on both inner walls of the main body 6, each of which is compatible with the first card slot. Furthermore, a single mounting slot 8 is defined on one side of each of the multiple mounting slots 7 located on the same side. Blocks 9 are slidably connected within the mounting slots 7 and the corresponding first card slots. A pair of these blocks 9 engage and connect within the second card slot defined on one side of the connecting rod 3. A spring 10 connects the block 9 to the inner wall of the mounting slot 7 on one side, ensuring that the block 9 automatically resets and snaps into the second card slot when no external force is applied.

[0027] To control the movement of the clamping block 9, the present invention also incorporates an operating mechanism within the second mounting groove 8. This operating mechanism comprises a rotating disk 17, which is slidably connected to the outer circumference of the rotating shaft 4 via a stopper and a stopper groove. A circular groove 18 is defined at the top of the rotating disk 17, and a third clamping groove is defined at the bottom of the groove 18. Two symmetrical connecting blocks 16 are slidably connected within the third clamping groove. A connecting tube 15 is fixedly connected to the top of the connecting block 16. The connecting tube 15 is positioned within the groove 18 and slides through the bottom inner wall of the second mounting groove 8. Multiple steel wire ropes 13 are fixedly connected to the center of the top of the connecting block 16. Each of the steel wire ropes 13 is located within the connecting tube 15 and is respectively routed around the outer circumference of a corresponding pulley 12, thereby being fixedly connected to one side of the corresponding clamping block 9. Thus, when the rotating disk 17 moves downward, it drives the connecting block 16 and the connecting tube 15 downward, which in turn pulls the clamping block 9 outward via the steel wire ropes 13, releasing the fixed connection between the outer sleeve 2 and the connecting rod 3.

[0028] To accommodate conveyor belts of varying widths, the present invention incorporates extension rods 19 and 20 on the adjacent sides of the two crossbeams 1. Both extension rods 19 and 20 are slidably connected within the interiors of the two crossbeams 1, allowing their extension lengths to be adjusted by sliding. To secure the adjusted crossbeams 1, the present invention incorporates a fixing pin 22 slidably connected to the bottom of one side of the crossbeam 1. The fixing pin 22 slides through the crossbeam 1 and into one of the multiple through-holes 21 formed on one side of the extension rod 20, securing the crossbeam 1.

[0029] To enhance the practicality and safety of the shelter, the present invention also features hanging rings 23 fixed to the bottom of the crossbeams 1 for suspending workers' safety belts or construction equipment. Furthermore, a waterproof tarpaulin 25 is fixed to the tops of multiple crossbeams 1 to protect against rain and dust. This tarpaulin 25 covers the tops and sides of the multiple support structures, protecting the vulcanization process from the external environment. A door curtain 26 for worker access and an exhaust fan hole 27 are located on one side of the tarpaulin 25, respectively, for later installation of an exhaust fan.

[0030] This application can be used in the field of belt conveyor belt maintenance, and can also be used in other fields applicable to this application.

[0031] Example 2: Reference Figures 1-6 , improved on the basis of embodiment 1: a special protective shed for belt conveyor belt vulcanization operation, which is applied to the field of belt conveyor belt maintenance, and a universal wheel 24 is set at the bottom of the support rod 5 to facilitate the movement of the protective shed.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
