Description
Technical field
The present invention relates to hydraulic dynamometer, particularly the dismounting servicing unit and the method for dismounting of a kind of hydraulic dynamometer of marine diesel and jackshaft connecting bolt.
Background technology
Marine low speed diesel engine is in debug process, and its power output need be measured by hydraulic dynamometer.The main shaft of diesel engine main shaft with just can carry out run-in synchronism after the hydraulic dynamometer flange shaft will be connected by jackshaft, carry out the mensuration of diesel engine power.
As shown in Figure 1, Fig. 1 is the connection diagram of marine diesel, jackshaft and hydraulic dynamometer.As seen from the figure, the output shaft of diesel engine (1) is connected with an end of jackshaft (2), and the other end of jackshaft (2) is connected on the flange shaft (31) of hydraulic dynamometer (3) by connecting bolt (5).When hydraulic dynamometer (3) carries out power measurement to diesel engine (1), the conventional method that prior art adopts is, earlier jackshaft (2) is connected with the flange shaft (31) of hydraulic dynamometer (3) during installation, assembly with hydraulic dynamometer (3) and jackshaft (2) is connected with the main shaft of diesel engine (1) again, and hydraulic dynamometer (3) is to adopt 12 big connecting bolts (5) to fix with being connected of jackshaft (2); When after debugging is finished to diesel engine (1), dismantling, at first the assembly of hydraulic dynamometer (3) and jackshaft (2) and the main shaft of diesel engine (1) are taken apart, then the flange shaft (32) of jackshaft (2) with hydraulic dynamometer (3) split.In this process, the weight of each connecting bolt need all have been dismantled them come and jackshaft (2) could have been separated with the flange shaft (32) of hydraulic dynamometer (3) all greater than 50Kg, and the connecting bolt (5) under will dismantling then places in order to using next time.
There are the following problems for above-mentioned prior art:
Because connecting bolt is bigger, need the connecting bolt of 12 weight altogether greater than 50Kg, therefore the mounting or dismounting that require a great deal of time are used to connect the connecting bolt of diesel engine main shaft, dynamometer flange shaft and jackshaft three parts, inefficiency, and extensive work is by manually finishing, live load is big and dangerous, and the connecting bolt that disassembles is lost the inconvenience that causes use next time easily.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, a kind of hydraulic dynamometer of marine diesel and the dismounting servicing unit and the method for dismounting of jackshaft connecting bolt are provided.Utilize hydraulic dynamometer and the dismounting servicing unit of jackshaft connecting bolt and the dismounting efficient that method for dismounting can improve connecting bolt greatly of marine diesel of the present invention, save human cost, and can effectively prevent the generation of the problem of losing etc. because of the connecting bolt of pulling down.
Technical scheme of the present invention:
A kind of dismounting servicing unit of connecting bolt, this servicing unit is the annular device that the additional flange by two semi-round ring shapes connects into, described attachment flange comprises semicircle flange watt, be fixed in the ring flange and the fixed head of the semi-round ring shape on the flange watt outer wall, the internal diameter of described flange watt equals the external diameter of the flange shaft on the hydraulic dynamometer, the internal diameter of described ring flange equals the external diameter of flange watt, ring flange be fixed on the outer wall of flange watt two ends to thereafter respectively vertical fixing on fixed head, described ring flange is provided with the screw identical with flange, and described fixed head is provided with fixing hole.
The method that a kind of dismounting servicing unit that utilizes described connecting bolt is dismantled hydraulic dynamometer and jackshaft connecting bolt, this method is to connect the flange shaft of hydraulic dynamometer and the connecting bolt dismounting of jackshaft, and then hydraulic dynamometer separated with jackshaft, it is characterized in that this method comprises the steps:
1. produce the described dismounting servicing unit of claim 1, this servicing unit is made up of two semicircular additional flange, additional flange is provided with identical screw on the flange shaft with described hydraulic dynamometer, and fixes a handle on first nut collar on the connecting bolt;
2. two additional flange are stuck on the flange shaft, move to apart from the distance of flange position less than connecting bolt length, aim at screw and each connecting bolt, two additional flange are fixed into complete dismounting servicing unit after passing fixing hole on the fixed head with stove bolt;
3. unclamp second attaching nut of the most easy-operating connecting bolt, move apart connecting bolt after this second attaching nut is pulled down, will also take off by the second middle nut collar with being clipped in second attaching nut and flange then;
4. spur the handle of first nut collar, move position to the dismounting servicing unit, on penetrating additional flange in should a screw of connecting bolt, continuing to move appears the end of connecting bolt in screw, second nut collar that takes off is mounted to the connecting bolt that appears in additional flange, to be screwed onto on the connecting bolt from the second nut collar outside with second attaching nut who takes off then, and tighten this second attaching nut and make second nut collar be close to the ring flange of additional flange;
5. be connected to all the other connecting bolts on the servicing unit successively according to the method for step in 4., after during to the dismounting of last connecting bolt jackshaft being pulled down from the flange shaft of hydraulic dynamometer, again connecting bolt is fixed on the servicing unit, finish the disassembling section of hydraulic dynamometer and jackshaft connecting bolt, carry out directly unclamping servicing unit when diesel engine power is measured to next time connecting bolt is fixed on the jackshaft;
Technique effect of the present invention:
1. increase work efficiency.Add that an additional flange can need not pull down connecting bolt and directly be fixed on the additional flange when taking jackshaft and hydraulic dynamometer flange shaft apart.Simple to operate, fast.
2. load lightens one's labor.Because adpting flange is bigger, connecting bolt generally greater than 50Kg remove need be bigger live load, if adopt new method, promptly directly will be bolted on the additional flange.Saved the connecting bolt that is used to connect jackshaft and hydraulic dynamometer flange shaft and pulled down, time saving and energy saving.
3. raising safety.Because the conventional method bolt is directly pulled down by hand, safety can't ensure; The present invention has then avoided this situation, improves processing safety.
Reduce management cost.Need the vanning management after the conventional method bolt is pulled down, phenomenon takes place to lose sometimes; The present invention has then avoided this situation to take place, and has improved the management of bolt.
