Description

Technical Field

[0001] The utility model relates to the field of crushers, and particularly relates to a fixing structure for a pulley protective cover of a gateway crusher. Background Art

[0002] The crusher for coal mine gateways is used in the gateways of fully mechanized coal mining or fully mechanized caving working faces. It is located in the middle section of the gateway conveyor. Its function is to crush raw coal, gangue and other materials transported out by the face scraper conveyor to an appropriate particle size for subsequent belt conveyor transportation. The gateway crusher adopts a compact design to adapt to the limited space conditions underground.

[0003] The back of the pulley protective cover of the gateway crusher is fixed longitudinally by bolts to the crushing frame and the main frame, making the pulley protective cover in a suspended state without surrounding support. During the underground production process, affected by external environments (coal and gangue blocking the gap below between the protective cover and the frame) and factors such as the impact of broken coal blocks inside the equipment, the position of the protective cover shell often deforms. Even in a better working face environment, the disassembly and maintenance of the internal belt are not conducive due to the deformation of the outer shell, increasing the maintenance time, reducing work efficiency, and thus causing abnormal shift maintenance, resulting in economic losses and labor losses. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a fixing structure for the pulley protective cover of a gateway crusher, which can increase the reinforcement support for the pulley protective cover, stabilize the installation position of the protective cover, reduce the deformation of the cover body, facilitate disassembly and maintenance, reduce redundant maintenance time, save resources, and reduce labor losses.

[0005] To achieve the above purpose, the utility model proposes the following technical solutions:

[0012] Preferably, an arc surface matching the peripheral shape of the pulley protection cover is provided on the vertical plate, which is convenient for welding and fixing with the pulley protection cover and strengthens the welding effect.

[0013] Preferably, there are two horizontal support points on the periphery of the pulley protection cover, namely the first horizontal support point and the second horizontal support point. The first horizontal support point is arranged at the connection position between the middle part of the periphery of the pulley protection cover and the crushing frame, and the second horizontal support point is arranged at the connection position between the bottom of the periphery of the pulley protection cover and the main body frame; a third horizontal support point is arranged on the back of the pulley protection cover. The first horizontal support point, the second horizontal support point and the third horizontal support point are threadedly connected to the transverse reinforcing rib through the transverse fixing base, thereby forming multiple horizontal support points and further optimizing the horizontal support effect.

[0014] Preferably, one vertical plate is provided on the transverse fixing base used at the first horizontal support point; two vertical plates are provided on the transverse fixing base used at the second horizontal support point; one or two vertical plates are provided on the transverse fixing base used at the third horizontal support point.

[0015] During use, only need to fix the transverse fixing base and the longitudinal fixing base at the designated positions on the pulley protection cover in sequence, then the longitudinal fixing base is threadedly connected to the longitudinal ear plate, and the transverse fixing base is threadedly connected to the transverse reinforcing rib, and then the fixing of the pulley protection cover is completed.
