Description
Technical field
The utility model relates to driving chassis forward beam corollary equipment field, particularly relates to a kind of driving chassis forward beam Finial device.
Background technology
All-hydraulic driving chassis is that underground mine uses relatively universal tunnelling equipment, have turn to flexibly, mobility strong, the motion control feature such as accurate, easy and simple to handle rapidly.But in the excavation operation of long-term down-hole, find that this equipment forward beam front end and dead head set bolt often occur that fracture pulled by bolt, occurring time serious that forward beam leading portion fixing hole thread damage is scrapped needs to change forward beam.
Pass through observation analysis, when the reason that discovery causes forward beam front end installation bottom outlet thread damage and dead head set bolt to pull fracture is excavation operation normal due to chassis, be 200bar during hydraulic system propelling pressure normal operating conditions, when hammer drill advances drill steel to push ahead rock drilling operation, the top wall that withstands on tightly is helped and with fixing forward beam, rock drilling eye position is not offset.Now to receive both direction contrary the top of dead head and below, sizable power.Because top stress point and bolt installation site exist certain distance, when top stressed time effect in moment under erection bolt will be subject to a reverse pulling force, the screw thread that long working easily causes set bolt to pull to rupture even forward beam to install bottom outlet damages and causes whole forward beam repair and replacement or scrap.
Utility model content
For above problem, the utility model provides a kind of driving chassis forward beam Finial device, it is installed and used, forward beam front end and dead head fixed bolt hole can be avoided to damage, reduce the consumption of overhaul of the equipments that chassis causes due to forward beam fault and spare parts cost, improve chassis operating efficiency, for reaching this object, the utility model provides a kind of driving chassis forward beam Finial device, comprise dead head and top skin, described dead head comprises lower dead head, upper dead head, top skin mount pad, upper forward beam installation portion and lower forward beam installation portion, described upper dead head is on lower dead head, there is drilling tool to stretch out in described upper dead head and use U-shaped hole, the drilling tool that the end winding support of drilling tool of driving chassis hammer drill main body side is arranged on dead head stretches out with in U-shaped hole, top skin mount pad is had on front side of described lower dead head, 1 top skin installing hole and 4 top skin locating holes are had in described top skin mount pad, described top skin locating hole angularly around top skin installing hole center one week, described top skin is column, described top skin is arranged in the top skin mount pad of lower dead head side, upper forward beam installation portion and lower forward beam installation portion is had on rear side of described lower dead head, 2 installing holes are respectively had in described upper forward beam installation portion and lower forward beam installation portion, the end winding support of the forward beam of driving chassis hammer drill main body side is arranged in forward beam installation portion and lower forward beam installation portion.
Further improvement of the utility model, there is drilling tool upper limit installing hole both sides, described upper dead head upper end, and the utility model carries out spacing by arranging drilling tool upper limit installing hole to drilling tool.
The utility model provides a kind of driving chassis forward beam Finial device, the application redesigns dead head profile: by top skin position design with forward beam horizontal level, make propulsive force direction become with two power in reaction force direction sized by the power of the contrary same level position of relative direction, eliminate when top stressed time effect in moment under the reversal interlocking relay that affords of erection bolt, thus avoid set bolt, damage that forward beam installs bottom outlet screw thread.In addition the application redesigns top skin profile: changed in shape by original cheese by top skin and be designed to cylindrical, material is still rubber quality.By redesigning, top skin is adapted to the roadway construction of down-hole complexity more.Chassis is when the operation of rough tunnel wall side, and the cylinder design of lengthening can help operating personnel better to require to carry out rock drilling construction according to construction drawing.Meanwhile, newly-designed top skin is due to the lengthening of appearance and size, more wear-resisting, avoids and changes frequently.
