Abstract
The utility model discloses an automotive bolt spanner for sleepers. The bolt spanner is characterized in that a speed reducer and a combustion motor are mounted on a frame; a transmission shaft; a bevel gear shaft and an output shaft are installed in a box body of the speed reducer; an output shaft of the combustion motor is connected with the transmission shaft through a centrifugal clutch; two driving gears are mounted on the transmission shaft and respectively meshed with a high-speed clutch gear and a low-speed clutch gear installed in the middle of the bevel gear shaft; a speed-changing combined body is mounted between the high-speed clutch gear and the low-speed clutch gear, and is connected with a handle through a shifting block, an eccentric shaft and a positioning handle seat to realize speed changing; two spiral bevel discs are mounted on the output shaft; and a direction-changing combined body is mounted between the two spiral bevel discs and connected with a control mechanism, so that the two spiral bevel discs can be respectively meshed with bevel gears at the end parts of the bevel gear shaft to realize the direction changing. The utility model can realize non-loaded startup, avoid engine stalling, and meet the requirements of different rotation speeds and torques.
Description
One. technical field: the utility model relates to a kind of railroad maintenance instrument, particularly relates to a kind of sleeper automotive bolt spanner.
Two. background technology: at present, China is along with the railway great-leap-forward development, and railways train operation density, the weight of train, road speed improve constantly, and have aggravated the impact to the rail track joint, thereby the maintenance of railway seems more and more important.At present, change or safeguard that sleeper need adopt automotive bolt spanner, to increase work efficiency.Automotive bolt spanner generally is divided into two kinds of machine driving and hydraulic drives, wherein, the precise control of hydraulicdriven spanner moment of torsion, output torque is big, but complex structure, price is higher; And machine driving spanner no-clutch is easily suppressed car, and the moment of torsion design that all needs when unscrewing bolt of its rotating speed, and rotating speed is on the low side when screwing, and efficient is not high.
Three. the utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of and realize non-loaded startup, can avoid suppressing car, output different rotating speeds and moment of torsion, can adapt to the sleeper automotive bolt spanner of different circuit fastening bolt degrees of tightness with centrifugal clutch.
The technical solution of the utility model is: a kind of sleeper automotive bolt spanner, contain organic frame, decelerator and internal combustion engine are installed on the described frame, in the casing of described decelerator power transmission shaft is installed, bevel gear shaft and output shaft, the output shaft of described internal combustion engine is connected with described power transmission shaft by centrifugal clutch, two travelling gears are installed on the described power transmission shaft, these two travelling gears are meshed with high speed clutch gear and the low speed clutch gear that install at described bevel gear shaft middle part respectively, between described high speed clutch gear and the low speed clutch gear speed change zygote is installed, this speed change zygote passes through shifting block, eccentric shaft, position fixing handle seat is connected with handle, realize speed change, two spiral shell umbrella disks are installed on the described output shaft, between two spiral shell umbrella disks the commutation zygote is installed, this commutation zygote is connected with operating mechanism, make two spiral shell umbrella disks with described bevel gear shaft end the bevel gear engagement is installed respectively, realize commutation.
The lower end of described output shaft is equipped with the work sleeve.Described speed change zygote is that spline is connected with described bevel gear shaft, and described commutation zygote is that spline is connected with described output shaft.
The beneficial effects of the utility model are:
1, the utility model adopts centrifugal clutch, can realize non-loaded startup, can avoid suppressing car effectively during excess load, thereby starts soon high efficiency.
2, gear of the present utility model can be realized rotation speed change, with output different rotating speeds and moment of torsion, can increase work efficiency during high speed, can obtain than high pulling torque during low speed, thereby can adapt to the degree of tightness of different circuit fastening bolts, uses very convenient.
3, the utility model is reasonable in design, and it is applied widely, is easy to promotion and implementation, has good society and economic benefit.
Four. description of drawings:
Fig. 1 is the structural representation of sleeper automotive bolt spanner;
Fig. 2 is the structural representation of the gearbox of sleeper automotive bolt spanner shown in Figure 1.
Five. the specific embodiment:
Embodiment: referring to Fig. 1-Fig. 2, among the figure, 1-internal combustion engine, 2-decelerator, the 3-operating mechanism, 4-frame, 5-gear, 6-changement, the 7-sleeve of working, 8-output shaft, 9-centrifugal clutch, 10-casing, 11-high speed clutch gear, 12-speed change zygote, 13-shifting block, 14-eccentric shaft, 15-position fixing handle seat, 16-low speed clutch gear, 17-bevel gear shaft, the 18-zygote that commutates, 19-spiral shell umbrella disk, 20-power transmission shaft, 21-travelling gear.
The sleeper automotive bolt spanner forms 4 by internal combustion engine 1, centrifugal clutch 9, decelerator 2, operating mechanism 3 and frame.The output shaft of internal combustion engine 1 is in transmission connection by centrifugal clutch 9 and decelerator 2, through decelerator 2 internal gear transmissions, can realize the change of rotating speed and direction by gear 5 and changement 6, after output shaft 8 passes to work sleeve 7.
When commutation zygote 18 with above during spiral shell umbrella disk 19 tooth embeddings engagement output shaft be rotated counterclockwise, drive work sleeve 7 and unscrew nut; When commutation zygote 18 with below during spiral shell umbrella disk 19 tooth embeddings engagement, output shaft turns clockwise, and drives work sleeve 7 and screws nut.
The structure that changes the structure of gear, the mechanism that changes changement and change decelerator is enough formed a plurality of embodiment, is common variation of the present utility model and protection domain, does not describe in detail one by one at this.
