Abstract
The utility model requests to protect a sleeve operating mechanism for a sleeper bolt mechanical wrench, which consists of a reset spring, a sleeve operating rod, a sleeve shifting block and a connecting standard component, wherein the lower end of the sleeve operating rod is connected on a frame-type land/rail traveling mechanism of the sleeper bolt mechanical wrench; the sleeve shifting block is welded at the position close to a working sleeve; the sleeve shifting block extends in a shifting block groove of the working sleeve; the reset spring is connected between the upward middle part of the sleeve operating rod and the frame-type land/rail traveling mechanism; and the working sleeve is driven by pressing down or lifting the sleeve operating rod to move up and down. The mechanism adopts a more compact and effective direct connection sleeve shifting fork left and right operating link gear, effectively solves the frequent faults that under the field condition, the pressure lever is greatly easy to jam, deform and even break and the shifting fork does not work in place, and can sufficiently meet the process and safety requirements of maintenance on the heavy and high-speed railway line or the novel railway line for the high uniformity consistency of the buckling pressing force of the sleeper bolt.
Description
Technical field
The utility model relate to use on a kind of rail track, lightweight mobile bolt double (end) wrench, be specifically related to the sleeve operating mechanism of sleeper bolt impact wrench.
Background technology
In China's track traffic standard based on the wheel track traffic, rail is withheld union piece, exposes in the Nature on the one hand throughout the year, is standing dust, the fouling product infringement of wind and rain freeze thawing, train operation, on the other hand, running train makes track structure bear bigger load.Along with the newly-built and scope of heavy duty, high-speed railway is promoted, orbital maintenance maintenance work amount and maintenance cost sharply rise especially, works department press for use accurately, maintenance plant equipment efficiently, solve the Nature infringement or heavy duty, the big load of bullet train, the destruction that track structure, physical dimension and the rail that track structure is caused withheld union piece.For this reason, at the on-the-spot sleeper fastening operation of railway working system, satisfy the high construction process requirement of sleeper bolt buckle press uniformity consistency that guarantees the rail buckling piece, domestic each maintenance machinery equipment manufacturing man, hydraulicdriven single head, double end automotive bolt spanner and mechanically operated single head, double end automotive bolt spanner have been developed in succession, have his own strong points, respectively have it short.
With the akin double end automotive bolt spanner of the utility model in, as notice of authorization day be October 17 calendar year 2001, notice of authorization CN2454406Y, the patent No. 00244613.8, name is called " sleeper nut degree of tightness machine " disclosed technical scheme, and the operating mechanism of this impact wrench is made up of slide plate, shift fork and support bar, spring, slide plate branch sleeve and shift fork, the shift fork head is connected the support bar two ends, between establish spring, shift fork connects control stick.This machine has been realized the function of pine or tight track nut, but there are many defectives in operating mechanism, connects as support bar top and action bars hinge, and bite, distortion very easily appear in its hinge junction, even break support bar hinge place; And for example support bar bottom and shift fork be by the fastening connection of tender, the work sleeve of high speed rotating, and when contacting with shift fork, the frequent transmission of clockwise, counter-clockwise moment very easily causes the sliding tooth of loosening or screw thread of fastening connection tender, causes shift fork work not in place.
And for example, notice of authorization day is on October 29th, 2008, notice of authorization CN201140331Y, the patent No. 200720188686.7, name is called " internal combustion engine track bolt impact wrench " disclosed technical scheme, and notice of authorization day is on April 8th, 2009, notice of authorization CN201217143Y, the patent No. 200720012716.9, name is called " the motor-driven stud driver of novel hydraulic clutch " disclosed technical scheme, and they also all have similar defective.
The utility model content
The purpose of this utility model is to provide a kind of sleeve operating mechanism that can guarantee the sleeper bolt impact wrench in sleeve operating mechanism functional reliability and application life.
The technical solution adopted in the utility model is as follows:
A kind of sleeve operating mechanism of sleeper bolt impact wrench, described sleeve operating mechanism are connected on the frame type land/rail walking mechanism of sleeper bolt impact wrench, and act on the work sleeve of sleeper bolt impact wrench by shift fork.
Described sleeve operating mechanism is a Z font direct connection socket yoke operations linkage mechanism, and each sleeve is supporting to be provided with one.The sleeve operating mechanism is by back-moving spring, the sleeve control stick, sleeve shifting block and connection standard component are formed, the lower end of described sleeve control stick is rotatably connected on frame type land/rail walking mechanism by connecting standard component, the sleeve control stick is at the position welded sleeve shifting block near the work sleeve, the sleeve shifting block puts in the shifting block groove of work sleeve, upwards with between frame type land/rail walking mechanism be connected back-moving spring at sleeve control stick middle part, sleeve control stick upper end extends upward the formation control crank, by pressing down or lift the sleeve control stick, drive the work sleeve and upwards or down move.The path that moves up and down of described sleeve control stick is provided with the limited block that its scope of moving up and down is limited, and limited block is fixed on frame type land/rail walking mechanism.
Technique scheme of the present utility model compared with prior art, the sleeve operating mechanism has adopted more succinct effective direct connection socket yoke left and right sides operations linkage mechanism, efficiently solve under the field condition, bite, distortion very easily appear in the down-pressed pole of sleeve control stick, even break, and shift fork work frequent fault not in place, fully satisfied maintenance or new clothes circuit technology, the safety requirements high on heavy duty, the High Speed Railway to sleeper bolt buckle press uniformity consistency.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the sleeper bolt impact wrench of use sleeve operating mechanism;
Fig. 2 is the mounting structure schematic diagram of this sleeve operating mechanism.
The specific embodiment
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail below.
Referring to Fig. 1, present embodiment is that compact internal combustion engine 2 (are gasoline engines as many employings), gearbox 3 and sleeve operating mechanism and work sleeve 10 are constituted an integral body, is placed on frame type land/rail walking mechanism 1.Compact internal combustion engine 2 is the 5.5HP gasoline engine.The working method of gearbox 3 is: the power output of compact internal combustion engine 2 connects gearbox 3 medium power transmission mechanisms 11 (see figure 2)s, Poewr transmission mechanism 11 is given reducing gear with transmission of power, reducing gear passes to changement again, changement passes to the middle idle wheel of moment of torsion controlling organization 4 again, middle idle wheel with about work clutch gear engagement on the sleeve, transfer torque is given work sleeve 10, and changement is by 5 controls of commutation joystick.
