Abstract

The utility model relates to a mine dump truck cab fixing structure, in particular to an off-highway mine dump truck. One side of a shock pad mounting hole on the bottom of a cab is fixedly provided with a support seat, a chassis is fixedly provided with a support, the support passes through the bottom of a cab to be arranged on the middle of the support seat, the support is provided with a long eye hole, and the support seat and the support are fixedly connected through a pin shaft and a bolt. The mine dump truck cab fixing structure leads the cab to be firmly and reliably fixed through a combined fixing mode of the shock pad and the pin shaft, enhances shock performance, and prevents inner function parts to be damaged because of over large vibration. Simultaneously, because the pin shaft has the limit function, a fixing bolt of the cab does not bear shear force under the work conditions that a vehicle accelerates, brakes and turns and the like, thereby preventing the fixing bolt of the cab from being cut and the shock pad from being damaged because of distortion dislocation, and increasing comfortableness of the cab.

Description

Quarry tipper cab anchorage structure

Technical field

The utility model relates to a kind of quarry tipper cab anchorage structure, is non-highway quarry tipper especially.

Background technology

Non-highway quarry tipper is mainly used in metallurgy, mining industries such as coal, the non-constant of vehicle ' road conditions, and vehicle generally all is work in 24 hours, this just need provide a good working environment to chaufeur, the damping property of operator's compartment, traveling comfort is just extremely important, and damping property all is to provide by with bolt and Rubber shock-absorbing pad operator's compartment and chassis being connected and fixed usually, vehicle in the process of moving, can run into acceleration, braking, different operating modes such as turning, these operating modes all can cause the cab anchorage bolt to bear shearing force, if things go on like this, bolt will be cut off, and behind the bolt fracture, cushion blocking will twist the dislocation deformed damaged, and then causes the operator's compartment damping to lose efficacy.Ways of addressing this issue improves the bolt strength grade often and increases the quantity of bolt of rear end plate, and this can only can not deal with problems to a certain degree improving cushion blocking service life at all.

Summary of the invention

The purpose of this utility model is to provide a kind of can eliminate cab anchorage bolt fracture and cushion blocking damage, guarantees the quarry tipper cab anchorage structure that cab anchorage is solid and reliable.

Technical solution: the utility model comprises: operator's compartment, chassis, captive joint by bolt of rear end plate, packing ring, cushion blocking, nut with the chassis in the operator's compartment bottom, cushion blocking mounting hole one side is installed with bearing in the operator's compartment bottom, be installed with support on the chassis, support passes the operator's compartment bottom and places the bearing middle part, have the slot mesh hole on the support, bearing is connected with bolt by bearing pin with support.

The utility model utilizes bolt, packing ring, cushion blocking, nut that operator's compartment and vehicle frame are connected and fixed, and after operator's compartment base plate lower surface had increased bearing, the corresponding support with the chassis of bearing connected by bearing pin, bolt.Simple and practical.The utility model is by the combination fixed form of cushion blocking and bearing pin, make cab anchorage solid and reliable, possesses certain damping performance simultaneously, avoid functional elements such as in-to-in instrument appliance to vibrate excessive damage, because the hole on the chassis overhang is the slot mesh hole of above-below direction, fore-and-aft direction is a circular hole, bearing pin has limit function in the circular hole direction, the bolt of rear end plate that makes operator's compartment is under operating modes such as vehicle acceleration, braking, turning, do not bear shearing force, avoid the cab anchorage bolt to cut off, thereby cause cushion blocking distortion dislocation to damage.Bearing pin satisfies the buffering requirement of cushion blocking in slot mesh hole direction, and bearing pin bears radial weight, guarantees that cushion blocking and hold-down bolt bear axial load to greatest extent, avoids being subjected to shearing force and is cut off, thereby cause the cushion blocking infantile failure.The utility model can be eliminated the problem of damage of operator's compartment cushion blocking and bolt fracture, improves the traveling comfort of operator's compartment.

Description of drawings

Fig. 1 is the utility model operator's compartment scheme of installation;

Fig. 2 is the utility model cab anchorage structural representation.

The specific embodiment

In Fig. 1, the utility model operator's compartment 1 adopts 4 point modes to be fixed on the chassis 2.

In Fig. 2, each attachment point adopts bolt of rear end plate 3, packing ring 4, cushion blocking 5, nut 6, to drive Room 1 is affixed on the chassis 2, in order to eliminate the shearing force that bolt of rear end plate 3 bears, face down bonding at operator's compartment 1 bottom cushion blocking 5 mounting holes is connected to bearing 7, have axis hole on the bearing 7, be welded with support 8 on the chassis 2, have the slot mesh hole on the support 8, support 8 passes operator's compartment 1 bottom and places bearing 7 middle parts, the slot mesh hole is corresponding with axis hole, bearing pin 10 is connected bearing 7 by axis hole and slot mesh hole with bolt 9 and is fixing with support 8, before having limited the integral body of operator's compartment 1, cushion blocking 5 is avoided to displacement in the rear, bolt of rear end plate 3 bears radial shear power, satisfies the buffering deformation requirements of cushion blocking.

The utility model operator's compartment 1 and bearing 7, chassis 2 all can be designed for one with support 8.

Claims

1. quarry tipper cab anchorage structure, comprise: operator's compartment, chassis, captive joint by bolt of rear end plate, packing ring, cushion blocking, nut with the chassis in the operator's compartment bottom, it is characterized in that, cushion blocking mounting hole one side is installed with bearing in the operator's compartment bottom, is installed with support on the chassis, and support passes the operator's compartment bottom and places the bearing middle part, have the slot mesh hole on the support, bearing is connected with bolt by bearing pin with support.
