Tunnel furnace self-acting trailer system

Abstract

The invention discloses a tunnel furnace self-acting trailer system, which mainly comprises a self-acting trailer (1), a drawing-vehicle hydraulic cylinder (6) and a hydraulic supporting positioner (10). A wheel axle (2) and wheels (3) are arranged at the bottom of the self-acting trailer (1); the wheels (3) are positioned on a self-acting trailer rail (14); the drawing-vehicle hydraulic cylinder (6) is arranged in the middle of the self-acting trailer (1); a hook (9) is arranged at the tail end of a drawing-vehicle hydraulic cylinder piston rod (8) of the drawing-vehicle hydraulic cylinder (6); the hydraulic supporting positioner (10) is arranged on the front of the self-acting trailer (1), and is a double-action hydraulic cylinder; and a tenon (11) is arranged on a hydraulic supporting positioner piston rod (13) at two ends of the hydraulic supporting positioner (10) respectively. The self-acting trailer realizes accurate and reliable positioning through the supporting positioner and guarantees the precision requirement on an unloading vehicle. Meanwhile, the self-acting trailer is also provided with a limit switch, so the security coefficient is further improved; and the drawing vehicle on the self-acting trailer is hydraulically controlled.

Description

technical field [0001] The invention relates to the technical field of kilns, in particular to an automatic trailer system for tunnel kilns capable of realizing intelligent management of automatic feeding and discharging functions. Background technique [0002] Tunnel kiln is a modern thermal equipment for continuous firing. It is widely used in the firing production of ceramic products and is also used in metallurgical industries such as abrasives. [0003] Tunnel kiln is generally a long linear tunnel with fixed walls and vaults on both sides and top, and kiln cars run on tracks laid at the bottom. The combustion equipment is installed on both sides of the middle part of the tunnel kiln, which constitutes a fixed high-temperature zone - the firing zone. The high-temperature flue gas generated by combustion flows along the tunnel to the kiln head under the action of the chimney at the front end of the tunnel kiln or the induced draft fan. At the same time, the products ent...

Problems solved by technology

[0004] At present, the feeding and discharging of tunnel kilns are generally batched manually. The time accuracy of raw materials entering and leaving the kiln is affected by the proficiency of manual operation, which is difficult to control and directly affects the performance of the product. It is not only time-consuming and laborious, but also increases labor costs.
