Mining multi-purpose crawler type traction excavator truck-mounted crane

Abstract

The invention discloses a mining multi-purpose crawler type traction excavator truck-mounted crane comprising an excavating device, a dozer blade device, a working platform, a walking drive device, ahydraulic system, a power system, an electrical system and a lifting device. The excavating device includes an excavator bucket oil cylinder (1), a small arm (2), a small arm oil cylinder (3), an auxiliary arm (4), an auxiliary arm oil cylinder (5), a rotary oil cylinder (6), a large arm oil cylinder (7), a large arm (8), an excavator bucket (26), a swing frame (27), a steering rudder (23) and a side rotation oil cylinder (33); the dozer blade device includes a dozer blade (25) and a dozer blade oil cylinder (24); and the lifting device comprises a truck-mounted crane mechanism, a hydraulic landing leg mechanism and a traction hook (19). According to the mining multi-purpose crawler type traction excavator truck-mounted crane, a mining excavator and a small crane are organically combined,so that the function of excavation is achieved, the functions of goods loading and unloading and vehicle traction are achieved, the structure is simple, operation is convenient, and quickness and effectiveness are achieved.

Description

technical field [0001] The invention relates to a mine-used multi-purpose crawler-type traction excavator truck-mounted crane, which belongs to the technical field of mine mining. Background technique [0002] In the normal production process of coal mines, the transportation of materials is towed and transported by electric locomotives to the intersection of main road and construction roadway or the end of track laying. Loading and unloading trucks has become a difficult problem. Manual unloading of bulk materials is labor-intensive and time-consuming. Without the supervision of safety officers, workers are prone to illegal operations, and they directly use the method of pulling over mine carts to unload, which has a great negative impact on safe production. [0003] When unloading heavy large-scale mining equipment, hand chain hoist bolts and anchor cables are often used to lift and unload equipment. The construction speed is slow, and it affects other production work and ...

Problems solved by technology

[0002] In the normal production process of coal mines, the transportation of materials is towed and transported by electric locomotives to the intersection of main road and construction roadway or the end of track laying. Loading and unloading trucks has become a difficult problem. Manual unloading of bulk materials is labor-intensive and time-consuming. Without the supervision of safety officers, workers are prone to illegal operations, so they directly use the method of pulling over mine carts to unload, which has a great negative impact on safety production

[0003] When unloading heavy and large mining equipment objects, hand chain hoist bolts and anchor cables are often used to lift the loading and unloading equipment. The construction speed is slow, and it affects other production work and poses a certain threat to the safety of the roof.

[0004] During the process of carrying goods, workers often encounter muddy depressions. If they are not careful, they will easily slip and fall in the mud, causing accidents such as falls and bruises. Pushing, pulling, yanking, slamming stones under the wheel, etc., when it doesn't help, will use the reverse chain to pull

[0005] Existing mining excavators use a two-joint arm hinge mechanism. Due to the limitation of underground space, the joint points of the excavator arm will touch the roadway roof, anchor rod, and anchor cable, which reduces the safety factor of mine construction; during the construction of the excavator, the roadway There are often dead corners left in the construction, and manual repairs are often used in the later stage. Repeated construction wastes manpower, material and financial resources
