Problems solved by technology
[0003] 1. Unable to set the angle limit switch
In the field where the actual working conditions are harsh, this structure loses the protection of the limit switch, and it is very easy to cause connection failure, ranging from equipment shutdown to equipment damage;
[0004] 2. Since the electrical wiring is not allowed to be twisted, the steering angle of the supporting track is limited, the movement of multi-track equipment is not flexible enough, and the operating efficiency of the equipment is greatly reduced

The invention discloses a supporting device with four degrees of freedom. The supporting device comprises an auxiliary crawler belt, a gantry and a transfer belt conveyor steel structure device, a pivotal bearing is fixed at the upper end of the gantry, a pivotal support is fixed at the upper end of the pivotal bearing, the upper end of the pivotal support is connected with a supporting beam through a hinge shaft II, a supporting bracket is arranged at the upper end of the supporting beam and is connected with the supporting beam through a hinge shaft I, travelling wheels are arranged on the supporting bracket, and the transfer belt conveyor steel structure device is supported at the upper ends of the travelling wheels. Compared with an original spherical hinge structure, by the aid of the technical scheme, the supporting device has the four degrees of freedom, can meet the requirement on a larger included angle between a transfer belt conveyor steel structure and a crawler belt support, is wider in bearing capacity scope, and accordingly, is particularly applicable to medium, large and ultra-large strip mine equipment. The supporting device is simple in structure, changeable in form and more applicable to complicated working conditions of the strip mine equipment.
Description
technical field [0001] The invention relates to multi-crawler equipment in an open-pit mine, in particular to a supporting device for the auxiliary crawler of a large-scale multi-crawler earthmover. Background technique [0002] At present, in large-scale open-pit mining equipment, with the continuous increase of equipment capacity and specifications, a large number of multi-crawler traveling devices that cooperate with the auxiliary crawler and the main crawler are used. The main crawler bears the weight of the main equipment and supports it with the auxiliary crawler. A section of belt conveyor reproduces the steel structure device. It is usually realized in the form of a spherical hinge. But this form usually has the following disadvantages: [0003] 1. The angle limit switch cannot be set. In the field where the actual working conditions are harsh, this structure loses the protection of the limit switch, and it is very easy to cause connection failure, ranging from eq...
