Description

Technical Field

[0001] The invention relates to the technical field of mining machinery, and in particular to a prying trolley working device. Background Art

[0002] In tunnel projects such as highways, railways and underground mines, drill rods of rock drilling equipment such as rock drilling trolleys are often used for blasthole drilling operations. During this period, there are often problems such as uneven face after blasting and excavation, under-excavation of the contour on the circumferential section, and attachment of dangerous rock and active gangue. Occasionally, there will be problems such as large deformation of soft rock in the tunnel due to long-term compression by ground stress. The above situations constitute the main types of diseases in contour defect tunnels, which seriously threaten the normal construction progress and healthy operation status of the tunnel. For this reason, tools such as breaker hammers are often used in tunnel projects to perform operations such as expansion and brushing to trim the tunnel contour to eliminate contour defects. In the prior art, manual hand-held pneumatic picks, multi-tool (breaker hammer, eagle hook or milling wheel, etc.) excavators, special prying trolleys, manual hand-held hammering iron chisels, local blasting, and illegal grinding of the chisel at the front end of the drill arm of the rock drilling trolley are often used for related operations.

[0003] The prying trolley is an auxiliary equipment for mining or tunnel construction, mainly used in conjunction with drilling and blasting. The tunnel is affected by the impact of blasting, and there are unstable rubble stones on the sides and top. Before the equipment and personnel enter, the prying process must be carried out to ensure construction safety. With the increasingly stringent requirements for mining safety, the prying trolley equipment is replacing more manual operations.

[0004] The working device of the existing prying trolley mostly adopts a rotary drive structure, but for safety reasons, the angle of the swing arm cannot be too large, and the range of the rotary drive is not large, which will cause the local position to be overloaded and the rotary drive to be easily damaged. In addition, in the existing technology, the hammer mounting seat is directly bolted to the two end surfaces of the swing cylinder. Under the action of the alternating impact load of the hydraulic hammer and the prying bending moment, the swing hydraulic cylinder will leak oil at the swing cylinder joint surface and the plug or the swing cylinder will fail due to internal leakage within less than 3 months of use, seriously affecting the use of the whole vehicle.
