[0023] REFERENCE Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The utility model provides a kind of gear assembly detection device in crane turret, including storage mechanism 1 and push material mechanism 2 assembled in the upper of storage mechanism 1, storage mechanism 1 includes storage needle cylinder 101, further include: the bottom of storage needle cylinder 101 is fixedly installed with discharge pipe 102, the outer wall of discharge pipe 102 is sleeved with flexible mouth 4, flexible mouth 4 bottom central position and bottom two sides are fixedly installed with discharge net 401, the top of storage needle cylinder 101 is fixedly installed liquid level window 104;Push material mechanism 2 includes closure cap 201, the bottom of closure cap 201 is fixedly installed with threaded sleeve 204, threaded sleeve 204 is internally threaded with threaded rod 202, threaded sleeve 204 is rotatably installed with push plate 205 on the bottom, and the top of threaded rod 202 is fixedly installed with rotary rod 203.

[0024] Wherein, the inside of discharge pipe 102 is slidably installed with filter plate 3, the two sides of filter plate 3 are fixedly installed with clamping plate 301, filter plate 3 adopts larger aperture screen, filter plate 3 can be filtered by the pigment discharged through discharge pipe 102, filter plate 3 can filter the larger particles in pigment liquid, to avoid the situation that larger particle pigment enters into flexible mouth 4 and causes blockage, to ensure the stability of flexible mouth 4 when coating the gear surface with pigment, clamping plate 301 can limit and fix filter plate 3 when being installed in discharge pipe 102, to ensure the stability of filter plate 3 during operation, and when filter plate 3 needs to be disassembled and replaced later, it can be pushed into the inside of storage needle cylinder 101, and is taken out and replaced through the top of storage needle cylinder 101, and filter plate 3 is installed through the bottom of discharge pipe 102.

[0025] In specific use process, the two sides of storage needle cylinder 101 are fixedly installed with operating rod 105, the outer wall of two groups of operating rod 105 is sleeved with holding sleeve 106, operating rod 105 is convenient for staff to hold when using the device, to increase the convenience of staff operation when using the device, holding sleeve 106 increases the softness and friction of the outer wall of operating rod 105, improves the stability of staff holding operation.

[0026] Wherein, the outer wall of discharge pipe 102 is fixedly installed with two groups of anti-skid teeth 103, two groups of anti-skid teeth 103 are used in cooperation with flexible mouth 4, anti-skid teeth 103 increase the friction of the outer wall of discharge pipe 102, the stability of flexible mouth 4 sleeved on the outer wall of discharge pipe 102 is ensured through anti-skid teeth 103, to avoid the situation that flexible mouth 4 falls off when operating on the outer wall of discharge pipe 102.

[0027] Specifically, when the gear gap of the crane slewing ring needs to be detected, the paint liquid is stored in the storage needle cylinder 101, the threaded sleeve 204 at the bottom of the closure cover 201 is screwed on the top of the storage needle cylinder 101, so that the top of the storage needle cylinder 101 can be closed and sealed by the threaded sleeve 204 and the closure cover 201. By rotating the threaded rod 202 through the rotating rod 203 by the staff, the bottom push plate 205 can be lowered when the threaded rod 202 is rotated clockwise, and the paint liquid in the storage needle cylinder 101 can be extruded by the downward movement of the push plate 205. The paint liquid extruded by the push plate 205 is discharged into the inside of the flexible nozzle 4 through the discharge pipe 102, and the paint liquid in the flexible nozzle 4 is uniformly exuded through the discharge net 401 under the action of pressure, and the exuded paint liquid is attached to the outside of the discharge net 401. The staff inserts the flexible nozzle 4 into the gear groove by operating the device, so that the three gear surfaces can be painted at a time, greatly improving the efficiency of the staff in painting the gear surface by the device, and the quality of painting each surface of the gear can be ensured because the paint liquid is uniformly attached to the outside of the discharge net 401. The liquid level window 104 can display the liquid level in the storage needle cylinder 101.

[0028] For example: when the gear gap of the crane slewing ring is detected, most of the detection work is done by coloring method. When the traditional coloring method detection method is operated, the staff needs to hold a paintbrush to paint the gear surface. Because there are many gear surfaces, a single gear groove contains three surfaces, so the staff needs to paint at least three times when operating a gear groove, which requires the staff to repeatedly paint the gear surface, thereby greatly increasing the time-consuming of detecting the gear gap of the crane slewing ring, reducing the work efficiency, and affecting the quality of painting the paint when the paintbrush is not evenly dipped.

[0029] And in the specific use process of the present application: through the cooperation of the flexible nozzle 4 and the three groups of discharge nets 401, the device can paint the three surfaces of the gear groove at a time, greatly increasing the efficiency of painting the gear gap of the device, and the discharge net 401 is of the same specification, so that the surface is attached with the same paint liquid, ensuring the uniformity of painting the three groups of gear surfaces at a time, and improving the quality of detecting the gear gap of the device.

[0030] Reference Figure 5In a preferred embodiment, the inside of the threaded sleeve 204 is fixedly provided with two sets of stirring motors 5, the output ends of the two sets of stirring motors 5 are fixedly provided with shafts 501 of the push plate 205, the bottoms of the two sets of shafts 501 are fixedly provided with stirring paddles 502, the stirring motors 5 drive the stirring paddles 502 to rotate in the inside of the storage needle cylinder 101 through the shafts 501, and the rotation of the two sets of stirring paddles 502 can stir and mix the pigment liquid in the storage needle cylinder 101, thereby avoiding the solidification of the pigment liquid in the storage needle cylinder 101 and prolonging the storage time of the pigment liquid in the storage needle cylinder 101.

[0031] The inside of the push plate 205 is fixedly provided with two sets of mechanical sealing rings 207, the two sets of mechanical sealing rings 207 are sleeved on the outer wall of the shaft 501, and the mechanical sealing rings 207 can be mechanically sealed when the shaft 501 pushes the push plate 205, thereby avoiding the leakage of the raw material liquid through the gap between the shaft 501 and the push plate 205 and ensuring the stability of the push plate 205 when the push plate 205 pressurizes the pigment liquid.

[0032] Specifically, the outer wall of the push plate 205 is fixedly provided with a sealing ring 206, the sealing ring 206 increases the sealing performance of the outer wall of the push plate 205 when the outer wall of the push plate 205 contacts the inside of the storage needle cylinder 101, thereby avoiding the leakage of the pigment liquid through the gap between the push plate 205 and the storage needle cylinder 101.

[0033] For example, when the conventional detection device is used, the applied pigment liquid may dry and solidify when it is placed for a long time, and the pigment liquid cannot be applied when it dries and solidifies, thereby shortening the application period of the pigment liquid, causing the waste of the pigment, and increasing the detection cost.

The substitution can be a substitution of part of the structure, device, method step, or a complete technical solution. According to the technical solution of the present application and the inventive concept, equivalent substitution or change should be covered in the protection scope of the present application.
