Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of trolley equipment, and in particular to a trolley rib plate 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, grating plates, 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 grating plate 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, the cross beams of the trolley are usually used to support the grating plate. In order to improve the overall strength of the trolley, a cross rib (rib plate) is fixed between two adjacent cross beams to reinforce the trolley. However, during actual use of the trolley for calcination operations, although the grating plate can block most of the flames extending downward, due to the complexity of the calcination environment, some flames will reach the cross rib through the grating plate, and over time, the cross rib is easily damaged, thereby affecting the overall service life of the trolley. CONTENT OF THE UTILITY MODEL

[0004] In order to reduce the occurrence of the cross rib being burned out in the trolley, the present application provides a trolley rib plate protection device.

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

[0010] Optionally, the fixing member is a countersunk bolt, the countersunk bolt is threadedly connected to the protection half-pipe, and the rod part of the countersunk bolt is threadedly connected to the cross rib.

[0011] By adopting the technical scheme, the countersunk bolt as the fixing member can firmly fix the protection half-pipe to the cross rib, and the stability of the protection sleeve is ensured. The design of the countersunk bolt makes the head part not protrude from the outer surface of the protection half-pipe, so that the additional wear or interference caused by the protruding part is reduced, and the overall smoothness and durability of the device are improved.

[0012] Optionally, a plurality of threaded holes for connecting the countersunk bolt are formed in the cross rib, and the threaded holes are arranged equidistantly around the axis direction of the cross rib.

[0013] By adopting the technical scheme, when the upper part of the protection sleeve is eroded by the flame and is about to be damaged, the fixing of the countersunk bolt can be cancelled, the protection sleeve is rotated, the relatively complete part of the protection sleeve faces upward, and then the countersunk bolt is fixed in the adjusted threaded hole.

[0014] Optionally, the protection assembly includes protection half-rings arranged at the two ends of the protection sleeve, the protection half-rings are arranged at the ends of the protection sleeve and around the outer arc surface of the protection sleeve, and the two ends of the protection half-pipe are provided with structures for abutting the protection half-rings against the connection between the cross rib and the trolley beam.

[0015] By adopting the technical scheme, the protection half-rings at the two ends of the protection pipe can effectively cover the end edges of the cross ribs, reducing the situation that the cross ribs are directly damaged by the flame. Meanwhile, the abutting members firmly abut the protection half-rings at the connecting positions of the cross ribs and the trolley cross beams, ensuring that the protection half-rings will not be loosened or displaced during the working process, thereby improving the stability and reliability of the entire protection device.

[0016] Optionally, the outer wall of the two ends of the protection pipe is provided with threads, and the abutting member is an abutting nut threadedly connected to the outer wall of the end of the protection pipe, and the protection half-ring is fixedly connected to the end face of the abutting nut.

[0018] Optionally, the end of each of the two protection half-rings close to each other is provided with a groove, and the grooves of the two protection half-rings close to each other abut each other.

[0019] By adopting the technical scheme, the two ends of the protection half-ring are provided with grooves and the grooves abut each other when close to each other, which can effectively increase the contact area between the protection half-rings, improve the connection stability, and avoid dislocation or separation when subjected to external force. Meanwhile, the gap at the abutting position of the two protection half-rings can block the direct action of the flame on the cross rib.

[0020] Optionally, there is a gap between the two adjacent reinforcing blocks.

[0021] By adopting the technical scheme, the heat conduction between the reinforcing pipe, the protection pipe and the cross rib can be reduced.
