Abstract
Description
Technical Field
[0001] The utility model relates to the field of engine maintenance equipment, in particular to an engine maintenance frame and a carbon deposit removal device. Background Art
[0002] When the equipment in the engine compartment is repaired and maintained, a place is needed to install the repair equipment or place the commonly used repair tools. However, the existing engine compartment does not have a flat surface for installing the repair equipment and placing the repair tools, so the repair equipment and the placement of the repair tools need to be located outside the engine compartment. Workers need to go back and forth many times to operate the repair equipment or take the repair tools, which is not conducive to improving the workers' maintenance efficiency. Moreover, since there is no place for the workers' repair tools in the engine compartment, the repair tools are easily placed by the workers and left in the engine compartment, causing damage to the equipment in the engine compartment.
[0003] After long-term use, carbon deposits will form inside the engine, and it is necessary to clean the carbon deposits in the engine in time. The current cleaning method is to add a cleaning agent into the engine and fix one end of a rocker on the crankshaft of the engine. Then, the rocker is manually reciprocated to make the piston in the engine move up and down, so that the cleaning agent can fully contact the cylinder, piston and piston ring, thereby more fully removing the carbon deposits (especially the carbon deposits on the piston ring).
[0004] However, the swinging rocker needs to last for a sufficient time (about 2 hours) to completely remove the carbon deposits. At present, due to the manual reciprocating swinging rocker, one worker can only remove the carbon deposits from one engine, which has a low working efficiency and increases the labor intensity of the workers.

[0030] Embodiment 1:
[0031] like Figures 1 to 4 As shown, an engine maintenance frame includes: a mounting frame 1, a first fixing plate 11 and a second fixing plate 13, wherein the first fixing plate 11 is located below the mounting frame 1 and fixed to the mounting frame 1, the second fixing plate 13 is located below the mounting frame 1 and fixed to the mounting frame 1, the first fixing plate 11 is formed with a first through hole 111, the second fixing plate 13 is formed with a second through hole 131, and the second through hole 131 is located in front of the first through hole 111.
[0032] Furthermore, it also includes a connecting sleeve 12, which includes a middle part and a boss 121, and the two ends of the middle part of the connecting sleeve 12 are respectively fixedly connected to the boss 121, and the bosses 121 at both ends of the connecting sleeve 12 are respectively inserted into the first through hole 111 and the first connecting hole 920 of the engine lifting ear 92.
[0033] Furthermore, a first step surface is formed between the middle portion of the connecting sleeve 12 and the boss 121 , and the first step surfaces at both ends of the connecting sleeve 12 are in contact with the first fixing plate 11 and the engine lifting lug 92 , respectively.
[0034] Furthermore, the bosses 121 at both ends of the connecting sleeve 12 are respectively clearance-matched with the first through hole 111 and the first connecting hole 920. Since there is a tolerance in the distance between the two engine hanging ears 92 of the engine, the connecting sleeve 12 can move radially in the hole due to clearance fit, thereby ensuring that it can be smoothly inserted into the first connecting hole 920.
[0035] Furthermore, there are two first fixing plates 11 and one second fixing plate 13 .
[0036] Furthermore, it also includes a first bolt 14, a first nut 15 and a spring retaining ring 16. The connecting sleeve 12 is formed with a stepped hole 120. The first bolt 14 passes through the stepped hole 120 and the spring retaining ring 16 and is threadedly connected to the first nut 15. The first bolt 14 is in contact with the first fixing plate 11, and the first nut 15 is in contact with the engine lifting ear 92. The spring retaining ring 16 is threadedly connected to the first bolt 14. The spring retaining ring 16 is located in the stepped hole 120. The spring retaining ring 16 is used to limit the connecting sleeve 12 and the first bolt 14.
[0037] Furthermore, it also includes a first bolt 14, a first nut 15, a second bolt (not shown in the figure) and a second nut (not shown in the figure), the first bolt 14 passes through the first through hole 111 and the first connecting hole 920 of the engine hanging ear 92 and is threadedly connected with the first nut 15 to fix the first fixing plate 11 and the engine hanging ear 92, the second bolt passes through the second through hole 131 and the through hole of the water pipe bracket of the engine and is threadedly connected with the second nut to fix the second fixing plate 13 to the water pipe bracket of the engine.
[0038] During installation, first insert the boss 121 at one end of the connecting sleeve 12 into the first through hole 111, and then the first bolt 14 passes through the stepped hole 120. Then, the spring collar 16 is sleeved on the outer side of the thread of the first bolt 14, and the spring collar 16 is limited by hand so that it cannot rotate, and then the first bolt 14 is rotated, and the spring collar 16 moves axially (the principle is the same as that of the screw mechanism) until the spring collar 16 enters the stepped hole 120.
[0039] Since the diameter of the spring collar 16 is between the large hole diameter and the small hole diameter of the stepped hole 120, the enlarged portion of the first bolt 14 contacts the first fixing plate 11, so that the connecting sleeve 12 and the first bolt 14 are limited. The connecting sleeve 12 and the first bolt 14 cannot fall from the first fixing plate 11, thereby preventing the first bolt 14 and the connecting sleeve 12 from falling into the engine compartment when the mounting frame 1 enters the engine compartment for installation.
[0040] Then, the boss 12 at the other end of the connecting sleeve 12 is inserted into the first connecting hole 920 of the engine lifting ear 92 , and then the first nut 15 is threadedly connected with the first bolt 14 , so as to fix the first fixing plate 11 on the engine lifting ear 92 .
[0041] Since the first fixing plate 11 is located at the rear side, it is not stable to fix it only with the first fixing plate 11. Therefore, the second bolt is passed through the second through hole 131 and the through hole of the water pipe bracket of the engine, and then the second bolt is threadedly connected with the second nut to fix the second fixing plate 13 to the water pipe bracket of the engine. The three-point support on the front and rear sides improves the stability of the mounting frame 1.
[0042] The mounting frame 1 can be used to install maintenance equipment or place maintenance tools.
[0043] Among them, the engine can be an EA837 engine.
[0044] Embodiment 2:
[0045] like Figures 1 to 4 As shown, a carbon deposit removal device for the engine maintenance rack using the first embodiment also includes a motor 2, a rocker 5, a first connecting member 52 and a driving mechanism, wherein the motor 2 is fixedly mounted on the mounting frame 1, the rocker 5 is slidably connected to the mounting frame 1, and the motor 2 drives the rocker 5 to swing back and forth with the first connecting member 52 as the center through the driving mechanism, and the first connecting member 52 is connected to the crankshaft 91 of the engine 9 and drives the crankshaft 91 to swing back and forth.
[0046] Furthermore, the driving mechanism includes a crank structure 3 and a connecting rod 4, the crank structure 3 is fixedly connected to the output shaft of the motor 2, the side of the crank structure 3 away from the output shaft of the motor 2 is rotationally connected to the connecting rod 4, and the end of the connecting rod 4 away from the crank structure 3 is rotationally connected to the rocker 5.
[0047] Furthermore, it also includes a magnet 6, which is fixed to the rocker 5 by magnetic force, and the magnet 6 is adsorbed on the surface of the mounting frame 1 by magnetic force.
[0048] During operation, the screw rod 41 is first rotated relative to the connector 42 according to the model of the engine 9, thereby adjusting the length of the connecting rod 4 to adapt to engines of different sizes. After adjusting the length, the connecting rod 32 is inserted into the designated connecting hole 31 through the connector 42 according to the model of the engine 9, thereby adjusting the swing angle of the rocker 5 and further adjusting the movement stroke of the piston of the engine 9.
[0049] Thereafter, the mounting frame 1 is fixed above the engine 9 , and then the first connecting member 52 is passed through the rocker arm 5 and inserted into the hole of the crankshaft 91 , thereby fixing the end of the rocker arm 5 to the crankshaft 91 .
[0050] After adjusting the speed of the output shaft of the motor 2 using the existing adjustment method, the motor 2 is started, and the crankshaft 91 is driven to reciprocate in positive and negative directions by a crank rocker mechanism to drive the piston in the engine to move, thereby removing carbon deposits inside the engine.
[0051] When adapting to different engines 9, the length of the connecting rod 4 and the position of the hinge point between the connecting rod 4 and the crank structure 3 will change, which causes the track of the rocker 5 relative to the mounting frame 1 to change when the rocker 5 moves. Therefore, if the rocker 5 and the mounting frame 1 are connected by a slide rail and a slider, it is necessary to replace a different slide rail to adapt to the change of the rocker 5 track, which is cumbersome to adjust and requires multiple slide rails.
[0052] The magnet 6 is used to be adsorbed to the mounting frame 1 through magnetic force. There is no need to replace the slide rail like the mechanical cooperation between the slide rail and the slider. The magnet 6 only needs to be manually placed at the corresponding position of the rocker 5 for position adjustment, which reduces costs and simplifies the adjustment steps.
[0053] Moreover, the slide rail and the slider are respectively fixed to the mounting frame 1 and the rocker 5. Due to the narrow space in the engine compartment, there is a risk that the worker's hand will be pinched by the slide rail and the slider when the worker performs other operations. However, the fixation of the magnet 6 to the rocker 5 is not mechanical, so when the magnet 6 hits the hand, it will be forced to slide on the rocker 5 or detach from the rocker 5, avoiding pinching of the hand.
[0054] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
