Description

Internal combustion fax motivation wrench

Technical field

The utility model relates to a kind of track maintenance implements, is specially a kind of internal combustion fax motivation wrench.

Background technology

Develop rapidly along with railway technology, track heavy-duty, train high-speed overload are the inexorable trends of modernized railway development, the new strategy of railway speed governing speed-raising gives the time interval of permanent way maintenance operation fewer and feweri, original operating type, traditional maintenance means far can not adapt to the requirement of modernized railway development, how to free from the maintenance mode of high strength, poor efficiency, single plane operation, be the be engaged in new problem of systems face of worker.

Known, loosening, tighten bolt is the key operation project of works department, especially since gapless track is laid and is used, increase along with workloads such as the operation that switches tracks, destressing adjustment, cause the elasticity bolt workload sharply to strengthen, and traditional elasticity bolt mainly relies on handwork, not only labour intensity is big, of poor quality, because workman's quality differs, and makes buckle press widely different, does not reach the buckle press standard-required, simultaneously, inefficiency, the phenomenon of doing over again is many, has caused a large amount of labours' waste, increase cost of labor, shortened maintenance cycle; Though the impact wrench of elasticity bolt also occurred can be used for, but it is because design, reason in the manufacturing, the machine components low precision, body structure, parts are provided with unreasonable, make the damage frequency height, and the maintenance difficulty is big, the accessory costliness, purposes is single, can only advance the operation of bolt degree of tightness, carries out the drilling of the rail if desired, operations such as polishing, impact wrench can't be finished these operations, so do not reach the purpose of a tractor serves several purposes, can not give full play to the facility advantage, and when on the rail of different model, using, because it is highly different, the angle of sleeper bolt and sleeve can be bigger, and needing to change the different sleeve of length could normally use, and has brought inconvenience to operation.

This shows in actual shipment is produced, how to make full use of of short duration headway time interval and carry out forming of circuit and protect maintenance activity, guarantee that railway security runs without interruption on schedule, is the key subjects of pendulum in face of ours.Current, Railway Reform enters the critical period, and the emphasis of reform just develops towards aspects such as large conveying quantity, high density, safe and efficient, speed-raisings completely.Under this background, develop a kind of highly effective, light weight, convenient, the rational in infrastructure impact wrench durable, that also can fully utilize in road has deep realistic meaning up and down.

The specific embodiment

Internal combustion fax motivation wrench, comprise frame 1, the same with other impact wrench, road wheel 20 also can be installed in the frame below, the power set 2 that generator and motor constitute are installed on the frame 1, generator adopts the steam turbine oil miscella, generator is provided with the throttle automatic regulator, be connected by forward and reverse running control circuit between generator and the motor, frame 1 is provided with the rotating conversion knob 3 of this control circuit and the action button 4 of motor, these two buttons can be arranged on handle 18 positions of frame, are convenient to people's operation, and rotating conversion knob comprises pine, tightly, stop three gears; Frame 1 below is provided with the assistor 5 that is connected with motor output end, and assistor 5 belows are provided with wrench socket 6, also can set up planetary gear speed reducing mechanism between assistor and the motor; Flexibly connect between assistor 5 and the frame 1, and be provided with angle automatic regulator 7, as shown in Figure 2, angle automatic regulator 7 comprises shell 8, and the block 9 that has through hole is set in the middle of the enclosure, and block 9 one sides are provided with to be inserted in the shell and expansion link 10 terminal and that through hole cooperatively interacts, be set with spiral compression spring 11 on the expansion link 10, be provided with spiral back-moving spring 12 between block 9 opposite sides and the shell 8, expansion link 10 external parts are connected with assistor 5, and shell 8 other ends are connected with frame 1.Frame 1 is provided with torque detecting apparatus, this device comprises torque sensor and control box 19, be provided with the signal detection treatment circuit that is connected with the torque sensor output in the control box 19, control box 19 surfaces are provided with the instrument board 17 that comprises voltmeter 13, torque meter 14, torque adjustment knob 15 and flashing light alarm indicator lamp 16.The torque setting value can be divided into 80N.m, 120N.m, 160N.m, 200N.m and " manual control " shelves, selects according to the buckle press value of bolt needs.

The using method of this impact wrench is as follows:

One, bolted operation

Starter-generator is observed Pressure gauge, checks that voltage can carry out next step operation after normal; Turn torque adjustment knob is to needed torque value; The position that knob points to " tightly " is changed in rotating; Sleeve is placed the nut top, according to different rail types, adjusting angle automatic regulator, the concentricity of maintenance sleeve and bolt; The push button, sleeve will rotate by clockwise direction, carry out the bolted operation, adopted converter technique simultaneously, the initial speed of sleeve is lower, be easy to just sleeve to be placed on the nut, and the unlikely nut that causes damages, and rotating speed improves step by step afterwards, finally with the rotating speed rotation of 1700r/min, and act on the nut with the ram type boosting mechanism, very high operating efficiency is arranged;

In fastening bolt, torque sensor detects the bolt torque value automatically, and detection signal is delivered to the signal detection treatment circuit, when reaching the torque setting value, and the indicator lamp warning of just flashing, prompting operation person has reached the torque value of setting.Will all the time action button be in down state when fastening bolt, impact wrench just can stop operating when decontroling button.

Two, bolt unclamps operation

Knob is changed in rotating rotated to " pine " position; And the action button of pressing the handgrip position can be unclamped operation; Decontroling action button when unclamping bolt to correct position stops operating.Do not need to set torque value when unclamping bolt, the value that the torque adjustment knob sets is inoperative in unclamping the bolt operation, and impact wrench can be added on total power on the nut, can guarantee to unclamp the dead bolt of rust like this.
