Description

TECHNICAL FIELD

[0001] The present application relates to the field of protection devices for trolley side beams, and particularly relates to a trolley side beam protection device. BACKGROUND

[0002] In many aspects of industrial production, such as steel smelting, ceramic firing, etc., trolleys play a crucial role as key material transportation and carrying equipment. A trolley is usually composed of a frame, wheels, side beams, grates, and a driving system. Its working principle is that the driving system drives the wheels to rotate, causing the frame to move on a predetermined track, thereby accurately transporting the material placed on the grates into a calcination furnace or other equipment for high-temperature processing. In the calcination process, the trolley needs to frequently enter and exit the high-temperature environment, and the material undergoes physical or chemical changes under the action of high temperature. During this process, high-temperature flames fill the working space.

[0003] In related technologies, to protect the trolley side beams from high-temperature flames, the conventional approach is to fix a protective plate on the upper end of the trolley side beams. In actual use of the trolley for calcination operations, the protective plate can play a certain protective role against the flames that directly reach the protective plate at the upper end of the trolley side beams. However, due to the complexity of the calcination environment, some flames will reach the protective plate through the grates of the trolley. More critically, these flames will continue to spread along the side wall edge of the protective plate and eventually reach the trolley side beams. Long-term exposure to such high-temperature flame erosion seriously threatens the structural integrity of the trolley side beams, frequently causing deformation, damage, and other problems. This not only shortens the service life of the trolley side beams and increases equipment maintenance costs, but also may cause production interruptions, affecting the stability and efficiency of the entire production process. CONTENT OF THE UTILITY MODEL

[0004] In order to reduce the burning of the trolley side beams, the present application provides a trolley side beam protection device.

[0005] The trolley side beam protection device provided by the present application adopts the following technical solution:

[0006] A trolley side beam protection device includes a plurality of protective plates arranged along the length direction of the trolley side beams. One end of the protective plate near the edge of the entire trolley extends downward. The other end of the protective plate is provided with an extension plate. The side of the extension plate away from the protective plate extends downward, and there is a gap between the end of the extension plate away from the protective plate and the trolley side beam. A fixing assembly is provided between the extension plate and the protective plate for fixing the two. A locking assembly is provided between the end of the protective plate away from the extension plate and the trolley side beam for fixing the protective plate on the trolley side beam.

[0007] By adopting the technical scheme, the fixed assembly firmly connects the extension plate and the protection plate, ensuring the structural stability. The protection plate is arranged along the length direction of the trolley side beam, and the end close to the edge of the trolley extends downward, which can effectively shield and protect the trolley side beam from direct impact of the flame. The setting of the extension plate further enhances the protection effect. The gap between the extension plate and the trolley side beam is not only conducive to heat dissipation but also can block the flame spreading from the side wall edge of the protection plate from directly acting on the trolley side beam, thereby improving the service life of the trolley and comprehensively improving the protection performance and safety of the trolley side beam.

[0008] Optionally, a slot is formed on one side of the extension plate close to the protection plate, and a plug is fixedly connected to the protection plate and inserted into the slot.

[0009] By adopting the technical scheme, the extension plate and the protection plate are preliminarily positioned by the cooperation of the slot and the plug, ensuring the accuracy during installation and improving the stability of the structure, thereby reducing the relative displacement during use.

[0010] Optionally, the fixed assembly includes a countersunk bolt threadedly connected to the side wall of the extension plate, and the rod portion of the countersunk bolt is threadedly connected to the plug.

[0011] By adopting the technical scheme, the extension plate and the protection plate are preliminarily positioned by the plug and the slot, and the plug is then fixed to the extension plate by the countersunk bolt, thereby improving the connection stability between the extension plate and the protection plate. The design of the countersunk bolt makes the fixed structure more compact, reduces the interference of protruding parts to the surrounding environment, and facilitates disassembly, assembly and maintenance.

[0012] Optionally, a plurality of reinforcing ribs are fixedly connected to one side of the protection plate close to the trolley side beam, and the reinforcing ribs abut against the upper end face of the trolley side beam.

[0013] By adopting the technical scheme, the reinforcing ribs can increase the contact area between the protection plate and the trolley side beam, thereby improving the structural strength and stability of the protection plate, effectively preventing the protection plate from deforming or falling off when subjected to external force, and reducing the heat conduction speed of the protection plate to the trolley side beam.

[0014] Optionally, there is a gap between adjacent two reinforcing ribs.

[0015] By adopting the technical scheme, the design of the gap between the reinforcing ribs can effectively reduce the overall weight of the protection device, provide heat dissipation space for the trolley side beam, and reduce the accumulation of heat between the protection device and the side beam, thereby improving the heat dissipation performance and service life of the protection device.

[0016] Optionally, the reinforcing rib is arranged in a T shape, and one end of the reinforcing rib with a large end surface area is in abutment with the trolley side beam.

[0017] By adopting the above technical solution, the reinforcing rib arranged in a T shape can increase the contact area with the trolley side beam, thereby improving the connection stability between the protective plate and the trolley side beam, effectively dispersing the acting force and reducing local stress concentration. The abutment of one end of the reinforcing rib with a large end surface area with the trolley side beam further enhances the stress support effect and improves the strength and reliability of the overall structure.

[0018] Optionally, the locking assembly comprises a locking bolt threaded through and connected to the protective plate, and a plurality of heat insulation pads are threaded through and slidingly connected to the rod portion of the locking bolt, and the heat insulation pads are in abutment with the trolley side beam.

[0019] By adopting the above technical solution, the locking bolt can firmly fix the protective plate on the trolley side beam, ensuring that the protective plate will not loosen or fall off during work, thereby improving the stability of the overall structure. The arrangement of the heat insulation pads effectively reduces the possibility of heat conduction from the protective plate to the trolley side beam, thereby protecting the trolley side beam from high temperature and prolonging the service life of the trolley side beam. At the same time, the sliding connection of the heat insulation pads makes the installation and adjustment more convenient, thereby improving the assembly efficiency.

[0020] Optionally, a plurality of cooling holes are formed in the end of the protective plate away from the extension plate, and the cooling holes correspond to and communicate with the gaps between adjacent two reinforcing ribs.

[0021] By adopting the above technical solution, the arrangement of the cooling holes can effectively enhance the heat dissipation performance of the protective plate, so that the heat generated by the trolley side beam when working in a high temperature environment can be quickly dissipated through the cooling holes, avoiding the accumulation of heat causing the deformation or damage of the protective plate. At the same time, the cooling holes communicate with the gaps between adjacent two reinforcing ribs, further promoting air circulation and improving the heat dissipation efficiency of the overall structure.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. The gap between the extension plate and the trolley side beam not only facilitates heat dissipation but also blocks the flame spreading from the side wall edge of the protective plate from directly acting on the trolley side beam, thereby improving the service life of the trolley and further improving the protection performance and safety of the trolley side beam;

[0024] 2. The design of the gaps between the reinforcing ribs can effectively reduce the overall weight of the protective device, while providing heat dissipation space for the trolley side beam and reducing the accumulation of heat between the protective device and the side beam, thereby improving the heat dissipation performance and service life of the protective device;

[0025] 3. The extension plate and the protection plate are preliminarily positioned through the insertion block and the insertion slot, and then the insertion block is fixed on the extension plate by using the countersunk bolt, so that the connection stability between the extension plate and the protection plate is improved.
