Description

Technical Field

[0001] The utility model relates to the technical field of natural gas compressor maintenance, in particular to a cylinder head pore carbon deposit cleaning device. Background Art

[0002] In the later stage of natural gas production, the supercharging process is mainly used for extraction. The supercharger is the key equipment for the supercharging process. Regular maintenance of the supercharger is the key factor to ensure stable production. The engine is the power equipment of the supercharger. The cylinder head intake and exhaust holes are the key components of the engine. The intake holes are the entrance channels for the fuel gas, and the exhaust holes are the exhaust channels for the exhaust gas. The pores work together to ensure the normal combustion of the fuel and the normal work of the engine, thereby providing stable power for the supercharger. If the pores are carbonized, the pores and valves will not be sealed tightly, and the combustion chamber will leak, resulting in insufficient engine power, causing engine abnormalities, and eventually causing the supercharger to fail and shut down.

[0003] Carbon deposits are deposits produced by incomplete combustion of the engine. Their main components are non-volatile substances such as asphaltene and oil coke. They adhere very tightly to the metal wall and are difficult to remove. In addition, the pore space is limited, generally with a diameter of 40mm, and the inner diameter gradually decreases. The inner wall surface is a curved surface, which makes it difficult to clean with conventional tools. Existing carbon deposit removal methods include dry ice removal, asphaltene cleaning agents, and manual tool removal. Considering the cost, carbon deposit removal rate, etc., manual tool removal is generally used on site.

[0004] However, the removal ability of manual tools is relatively limited, especially for areas with severe carbon deposits or deep locations, it may be difficult to completely remove the carbon deposits, resulting in poor removal results. Secondly, the manual tool removal method mainly relies on manual operation, and the operator may find it difficult to accurately control the force and angle, which increases the difficulty of operation, and further makes manual removal of carbon deposits slow and time-consuming, resulting in high labor intensity, high time cost, and low operation efficiency.

[0005] Therefore, it is necessary to study a cylinder head pore carbon deposit cleaning device to solve the above problems or alleviate the impact of the above problems. Utility Model Content

[0031] The utility model will be further described below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 5 As shown, the cylinder head pore carbon deposit cleaning device of the utility model may include a vertically erected load-bearing rod 1 and a first adjustment mechanism and a second adjustment mechanism both connected to the load-bearing rod 1, and the two ends of the load-bearing rod 1 are respectively connected to a driving component 2 and a cleaning brush head 3;

[0033] The first adjustment mechanism can adjust the horizontal position of the load-bearing rod 1, and the second adjustment mechanism can adjust the longitudinal position of the load-bearing rod 1, so as to adjust the cleaning brush head 3 to extend into the air hole to be cleaned; the driving component 2 can drive the load-bearing rod 1 to rotate, thereby driving the cleaning brush head 3 to rotate and clean the air hole to be cleaned.

[0034] Specifically, the cleaning device is integrally fixedly mounted on the cylinder head to clean carbon deposits from the air holes of the rod head. The load-bearing rod 1 is vertically set up, with the upper end fixedly connected to the driving component 2 and the lower end fixedly connected to the cleaning brush head 3. In this way, the driving component 2 is connected to the cleaning brush head 3 through the load-bearing rod 1, so that the driving component 2 can drive the cleaning brush head 3 to rotate and clean carbon deposits from the air holes of the cylinder body.

[0035] The first adjustment mechanism is connected to the load-bearing rod 1, and can adjust the position of the load-bearing rod 1 horizontally. The second adjustment mechanism is connected to the load-bearing rod 1, and can adjust the position of the load-bearing rod 1 longitudinally. In this way, the spatial position of the cleaning brush head 3 can be adjusted by adjusting the position of the load-bearing rod 1, so that the cleaning brush head 3 can be accurately extended into the air hole to be cleaned, and preparation can be made for the cleaning brush head 3 to rotate and clean.

[0036] When the cleaning device is used to clean carbon deposits in pores, the cleaning operation can be performed without manual hand-held tools, and the cleaning effect of carbon deposits can be ensured while greatly improving the cleaning efficiency of carbon deposits in pores.

[0037] In general, the cylinder head pore carbon deposit cleaning device of the utility model can accurately control the position of the cleaning pores by adjusting the position of the cleaning brush head 3 corresponding to the pores through the cooperation of the first adjusting mechanism and the second adjusting mechanism. The cleaning brush head 3 can be driven by the driving component 2 to rotate and clean the pores. The operation is convenient and the cleaning force can be controlled, thereby reducing the difficulty of removing carbon deposits from the pores and reducing labor intensity. At the same time, it can also improve working efficiency and enhance the carbon deposit removal effect.

[0038] In an example, Figure 1 and Figure 3 As shown, the cleaning device further comprises a bracket 4 for fixed support; the first adjustment mechanism comprises a guide rod 5 and a slider 6, the guide rod 5 is horizontally arranged on the bracket 4, the slider 6 is sleeved on the guide rod 5 in the horizontal direction and sleeved on the bearing rod 1 in the vertical direction;

[0039] The slide block 6 can move horizontally on the guide rod 5, thereby driving the load-bearing rod 1 to perform horizontal adjustment.

[0040] Specifically, the bracket 4 is used to fix the cleaning device as a whole on the cylinder head, which plays a role of stable support. The guide rod 5 is arranged horizontally and both ends of it are fixedly connected to the bracket 4, which can provide stable support for the slider 6. The slider 6 is sleeved on the load-bearing rod 1 in the vertical direction, so that the slider 6 and the load-bearing rod 1 are relatively fixed in the horizontal position. When the slider 6 moves horizontally, the load-bearing rod 1 also moves horizontally with it. The slider 6 is sleeved on the guide rod 5 in the horizontal direction, so that it can move horizontally along the guide rod 5, thereby driving the load-bearing rod 1 to move horizontally, so as to achieve the adjustment of the load-bearing rod 1 in the horizontal position.

[0041] In one example, the first adjustment mechanism includes two guide rods 5 arranged in parallel, and the ends of the two guide rods 5 are fixedly connected to the bracket 4 through a connecting frame 7; the slider 6 is provided with at least two guide holes in the horizontal direction for installing the guide rods 5.

[0042] Specifically, the first adjustment mechanism is provided with two parallel guide rods 5 on a horizontal plane, so that the front and rear ends of the slider 6 (such as Figure 3 The two guide rods 5 are respectively sleeved on the two guide rods 5 in the front and rear directions to ensure the stability of the slider 6 in the horizontal direction. Both ends of the guide rod 5 are fixedly connected to the bracket 4 through a connecting frame 7. At this time, the bracket 4 may include two parts respectively located at both ends of the guide rod 5, and a connecting frame 7 is horizontally fixed on the upper end of each part. The connecting frame 7 fixes the ends of the two guide rods 5 to form a stable support for the guide rods 5. The ends of the guide rods 5 and the connecting frame 7 can be fixed by threaded connection. The slider 6 is installed on the guide rod 5 through the guide hole sleeve, that is, the slider 6 is provided with at least one guide hole corresponding to one guide rod 5. It should be noted that when the slider 6 is composed of multiple parts in the length direction of the guide rod 5, that is, the multiple parts are sequentially provided with multiple corresponding penetrating guide holes.

[0043] In an example, Figures 1 to 3 As shown, the first adjustment mechanism further includes a locking member 8 disposed on the slide block 6 , and the locking member 8 is used to lock the position of the slide block 6 on the guide rod 5 .

[0044] Specifically, the locking member 8 is perpendicular to the axial direction of the guide rod 5 and penetrates the side wall of the guide hole, and can be pressed against the guide rod 5, so that the slider 6 is locked with the guide rod 5. In this way, when the slider 6 needs to be adjusted horizontally, the locking member 8 is unlocked, that is, it is not pressed against the guide rod 5, and the slider 6 can be adjusted horizontally along the guide rod 5; when the slider 6 needs to be fixed after the horizontal adjustment is completed, the locking member 8 is locked, that is, pressed against the guide rod 5, and the slider 6 is fixed with the guide rod 5.

[0045] Furthermore, the locking member 8 may be a bolt, which cooperates with the threaded hole on the slider 6 and the guide rod 5 to lock or unlock.

[0046] In an example, Figure 1 and Figure 3 As shown, a magnetic attraction member 9 for fixed installation is provided at the bottom of the bracket 4, and the magnetic attraction member 9 can fix the connection between the bracket 4 and the cylinder head.

[0047] Specifically, the bottom of the bracket 4 can be connected to the magnetic member 9 by magnetic attraction, and the magnetic member 9 is connected to the bar head by magnetic attraction to fix the bracket 4. Of course, the magnetic member 9 can also be fixedly installed at the bottom of the bracket 4. Preferably, the magnetic member 9 can use a strong magnet.

[0048] In an example, Figure 1 and Figure 3 As shown, the second adjustment mechanism includes a longitudinal adjustment component, which includes an adjustment bracelet 10 and a travel positioning sleeve 11 sleeved on the load-bearing rod 1, the adjustment bracelet 10 is fixedly connected to the travel positioning sleeve 11, and the travel positioning sleeve 11 is threadedly connected to the slider 6 of the first adjustment mechanism;

[0049] The adjusting bracelet 10 can drive the travel positioning sleeve 11 to spirally rotate relative to the slider 6, thereby driving the load-bearing rod 1 to perform longitudinal adjustment.

[0050] Specifically, the second adjustment mechanism performs longitudinal adjustment of the load-bearing rod 1 through a longitudinal adjustment component, and realizes longitudinal movement through the screw fit of the stroke positioning sleeve 11 and the slider 6 of the first adjustment mechanism. The outer surface of the stroke positioning sleeve 11 is provided with an external thread arranged in the longitudinal direction, and the center of the slider 6 is provided with an internal thread hole that matches and penetrates the external thread of the stroke positioning sleeve 11, so that the stroke positioning sleeve 11 can realize longitudinal movement while rotating in the internal thread hole of the slider 6. The adjustment bracelet 10 is fixedly connected to the stroke positioning sleeve 11, that is, the rotation of the adjustment bracelet 10 will drive the stroke positioning sleeve 11 to rotate synchronously, and the adjustment bracelet 10 can serve as the driving part of the stroke positioning sleeve 11. Furthermore, the external thread on the outer surface of the stroke positioning sleeve 11 can be a T-shaped thread.

[0051] The adjusting bracelet 10 rotates clockwise to drive the travel positioning sleeve 11 to rotate clockwise, so that the travel positioning sleeve 11 moves downward relative to the slider 6 for adjustment; the adjusting bracelet 10 rotates counterclockwise to drive the travel positioning sleeve 11 to rotate counterclockwise, so that the travel positioning sleeve 11 moves upward relative to the slider 6 for adjustment. In this way, when the longitudinal adjustment component and the load-bearing rod 1 are in axial positioning, the longitudinal adjustment component can cooperate with the slider 6 to spirally rotate through the adjusting bracelet 10 and the travel positioning sleeve 11, thereby driving the load-bearing rod 1 to perform longitudinal adjustment relative to the slider 6.

[0052] In one example, the second adjustment mechanism further includes a fixing assembly for locking the axial position of the longitudinal adjustment assembly and the load-bearing rod 1 , and the fixing assembly includes two fixing sleeves 12 respectively located at both ends of the longitudinal adjustment assembly, and the fixing sleeves 12 can be locked with the load-bearing rod 1 .

[0053] Specifically, the second adjustment mechanism realizes the axial positioning of the longitudinal adjustment component and the load-bearing rod 1 through the fixing component, so that the longitudinal adjustment component can drive the load-bearing rod 1 to adjust longitudinally relative to the slider 6. The fixing component is locked with the load-bearing rod 1 through the fixing sleeve 12, and the adjusting bracelet 10 and the stroke positioning sleeve 11 of the longitudinal adjustment component are axially fixed on the load-bearing rod 1 at a position between the two fixing sleeves 12. In this way, the longitudinal adjustment of the load-bearing rod 1 can be realized by adjusting the bracelet 10 and the stroke positioning sleeve 11 longitudinally relative to the slider 6.

[0054] It should be noted that the fixing sleeve 12 can also be unlocked from the load-bearing rod 1 to adjust the axial position of the longitudinal adjustment assembly on the load-bearing rod 1. When the fixing sleeve 12 is locked with the load-bearing rod 1, the longitudinal adjustment assembly can rotate circumferentially relative to the fixing sleeve 12, that is, the circumferential rotation of the load-bearing rod 1 is not linked to the circumferential rotation of the adjustment bracelet 10 and the travel positioning sleeve 11, and does not affect each other.

[0055] Furthermore, the fixing sleeve 12 can be fixed by passing bolts perpendicular to the axial direction of the load-bearing rod 1 through the fixing sleeve 12 .

[0056] In an example, Figures 1 to 3 As shown, a bearing 13 is provided between the fixing sleeve 12 and the adjusting bracelet 10 of the longitudinal adjusting assembly, so that the longitudinal adjusting assembly can rotate relative to the fixing sleeve 12 .

[0057] Specifically, the adjusting bracelet 10 is located above the travel positioning sleeve 11, and the adjusting bracelet 10 and the fixing sleeve 12 above it can be connected through the bearing 13. Specifically, the lower end of the fixing sleeve 12 forms a plane contact with the upper protective cover of the bearing 13, the lower protective cover of the bearing 13 forms a plane contact with the adjusting bracelet 10, and the upper protective cover and the lower protective cover of the bearing 13 are in rolling contact, so that the fixing sleeve 12 and the adjusting bracelet 10 can rotate relative to each other in the circumferential direction, that is, the rotation of the load-bearing rod 1 and the rotation of the adjusting bracelet 10 do not form a linkage effect.

[0058] Furthermore, the travel locating sleeve 11 is in smooth contact with the fixed sleeve 12 below it, that is, there is no friction between the travel locating sleeve 11 and the corresponding fixed sleeve 12 in contact, and they can rotate relative to each other in the circumferential direction, so that the rotation of the load-bearing rod 1 and the rotation of the travel locating sleeve 11 do not form a linkage effect. In this way, the work of the travel locating sleeve 11 for longitudinal adjustment by rotation can be separated from the work of the load-bearing rod 1 for cleaning the air holes by rotation, and the two do not affect each other. Of course, the travel locating sleeve 11 and the fixed sleeve 12 below it can also be connected by setting a bearing 13 to achieve the above function.

[0059] In one example, the adjusting bracelet 10 and the travel positioning sleeve 11 are fixed by a key connection or a pin connection.

[0060] Specifically, the adjusting bracelet 10 is sleeved on the axial extension portion of the upper end of the travel positioning sleeve 11, and a central mounting hole matching the structure of the axial extension portion is provided at the center of the adjusting bracelet 10. A key slot may be provided on the axial extension portion for key connection, or a pin slot may be provided for pin connection.

[0061] In one example, the driving component 2 is a hand wheel, and the structure of the cleaning brush head 3 matches the structure of the air hole.

[0062] Specifically, the driving component 2 is a hand wheel, which can manually drive the load-bearing rod 1 to rotate, so as to drive the cleaning brush head 3 to rotate coaxially, and provide driving force for the cleaning brush head 3 to clean the pores. The structure of the cleaning brush head 3 matches the structure of the pores, so that the cleaning brush head 3 rotates and rubs against the inner wall of the pores, which can better clean the inside of the pores, and can completely clean the inside of the pores to be cleaned by one adjustment, avoiding repeated adjustments and improving work efficiency.

[0063] In order to better understand the above embodiment, the operation flow of using the cleaning device to clean carbon deposits from the cylinder head air holes is further described in conjunction with the accompanying drawings.

[0064] First, the magnetic attraction part 9 at the bottom of the bracket 4 is fixedly connected to the cylinder head to form a stable installation for the entire cleaning device. Then, the horizontal position of the load-bearing rod 1 is adjusted by horizontally moving the slider 6 on the guide rod 5, so that the cleaning brush head 3 corresponds to the air hole to be cleaned, and then the slider 6 and the guide rod 5 are locked by the locking member 8 to achieve the fixation of the horizontal position; the two fixing sleeves 12 are fixed to the load-bearing rod 1, so that the adjustment bracelet 10 and the stroke positioning sleeve 11 are both axially fixed to the load-bearing rod 1, and the adjustment bracelet 10 rotates clockwise / counterclockwise to drive the stroke positioning sleeve 11 to adjust up and down relative to the slider 6 in the longitudinal direction, and then the cleaning brush head 3 is adjusted to extend into the air hole to be cleaned through the load-bearing rod 1 and positioned at a suitable carbon deposit cleaning position. Finally, the load-bearing rod 1 is driven to rotate by the driving component 2, and the cleaning brush head 3 is driven to rotate to clean the carbon deposits in the air hole.

[0065] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
