Abstract
The utility model discloses a shield machine hob torque detecting device, which comprises a circular cutter ring clamp ring rolled with a steel tape. The cutter ring clamp ring is provide with an opening, and two opposite connecting lugs are arranged at the opening and connected via a bolt. Convex lugs are welded on the outer side of the cutter ring clamp ring, and nuts are fixed to the convex lugs. The shield machine hob torque detecting device can be used for conveniently detecting whether torque of a shield machine hob meets requirements or not so as to discover problems in time for maintenance, and cost is saved.
Description
Technical field
The utility model relates to a kind of shield machine roller cutter torque detecting apparatus.
Background technology
Along with the expansion of national tier 2 cities urban rail transit construction, shield machine more and more enters people's the visual field.In the shield machine tunneling process, the quality of cutter affects planning, quality and the risk size in whole piece tunnel, so the initial stage is very necessary to the inspection of cutter.As everyone knows, the tunneling process of shield machine is exactly the working angles of the broken rock of cutter, the moment of torsion of hobboing cutter is important parameters in the cutting, because the power that hobboing cutter is rotated is to be provided by the friction force between hobboing cutter sword and its rock face that will cut in the cutterhead rotation process, so the necessary condition of broken rock is exactly after hobboing cutter has certain pressure to the rock stratum, when cutterhead rotated, the friction torque that hobboing cutter produces was enough to make hobboing cutter to rotate.This torque meeting is subjected to many restrictions such as the workmanship of hobboing cutter and technological problems, if used underproof hobboing cutter accidentally, consequence is very serious.Shield machine with the most frequently used Φ 6280 is an example, totally configuration 35 is hobboing cutter, totally 39 blades, and each blade is responsible for a Cutting trajectory that encloses, if wherein one does not change cutter, the cutter of track load strengthens around it so, aggravation wear extent, vicious cycle like this, cause overall cutter heel and toe wear, tool changing has in advance not only increased cost, has also increased the tool changing risk.So the inspection of cutter torque is very important, and does not have this type of simple tool that the moment of torsion of hobboing cutter is checked at present.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, shield machine roller cutter torque detecting apparatus of being convenient to operate.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of shield machine roller cutter torque detecting apparatus, it comprises the cutter ring snap ring of the circle that is rolled by steel band, described cutter ring snap ring opening, be provided with two relative connection journal stirrups at opening part, described two connect journal stirrup employing Bolt Connection, are welded with lug in the described cutter ring snap ring outside, are fixed with nut on described lug.
Adopt the beneficial effect that technique scheme produced to be: the utility model is simple in structure, be convenient to operation, and applicability is wide, not only can be used for shield structure building-site and check and accept instrument, also can be used as the examination instrument of cutter manufacturer to product.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode synoptic diagram;
Wherein, 1, cutter ring snap ring; 2, connect journal stirrup; 3, bolt; 4, nut; 5, lug; 6, cutter shaft; 7, cutter hub; 8, cutter ring.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, the utility model comprises the cutter ring snap ring 1 of the circle that is rolled by steel band (band steel), described cutter ring snap ring 1 is opening-like, be provided with two relative connection journal stirrups 2 at opening part, described two connect 3 connections of journal stirrup 2 employing bolts, be welded with lug 5 in described cutter ring snap ring 1 outside, on described lug 5, be fixed with nut 4.The diameter of cutter ring snap ring 1 should be complementary with the diameter of cutter ring.
Referring to accompanying drawing 2, during use that the cutter shaft 6 of hobboing cutter is fixing, the hobboing cutter cutter shaft is generally polygon, as trapezoidal, can make a shelf on a steel plate in the time of fixedly, and cutter shaft 6 fixations are got final product.Make cutter ring snap ring 1 chucking cutter ring 8 then, block nut 4 with the manual dial torque wrench of dial type, firmly rotation, the moment of torsion that shows on the spanner when cutter ring 8 rotates is the rotary torque of hobboing cutter for this reason.Usually moment of torsion is in 50Nm～75 Nm scopes.
The utility model is simple in structure, and applicability is wide, because cutter inevitably stained and corrosion can take place on-site, moment of torsion is increased, and adopts the utility model just can clear up maintenance easily voluntarily, and whether qualified, thereby save the cutter maintenance cost if detecting cutter.
