Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to a traveling mechanism of a sludge scraping and sucking machine in a sewage treatment plant. Background Technique

[0002] Sewage treatment refers to the removal or degradation of harmful substances in sewage through a series of physical, chemical or biological methods to ensure that the treated water body can meet the water quality standards for discharge or reuse. In the process of sewage treatment, a traveling mechanism of a sludge scraping and sucking machine in a sewage treatment plant is often required.

[0003] At present, the traveling wheels of sludge scraping and sucking machines in aeration grit chambers and secondary sedimentation tanks of sewage treatment plants often adopt a smooth track type or wheel type design, which is prone to slipping when freezing at low temperatures, or due to problems such as wear of rubber tires and the ground, resulting in difficult operation of equipment and facilities. General maintenance is time-consuming and laborious. To avoid the wear of the traveling wheels of the peripheral drive sludge scraping and sucking machine on the ground, steel plates are often paved on the ground, affecting normal production.

[0004] The above problems all show relatively large traveling wear and poor traveling stability, affecting the production efficiency and quality in the whole equipment processing process. Content of the Utility Model

[0005] The purpose of the utility model is to propose a traveling mechanism of a sludge scraping and sucking machine in a sewage treatment plant aiming at the deficiencies of the prior art, so as to solve the problems of relatively large traveling wear and poor traveling stability in the use process of existing equipment.

A traveling mechanism is arranged on the top of the rail main body. The traveling mechanism includes traveling wheels. A lubrication mechanism is arranged in the inner cavity of the traveling wheels. The lubrication mechanism includes a fixing rod. One side of the fixing rod close to the inner wall of the traveling wheel is welded to the inner wall of the traveling wheel.

[0008] Preferably, a sliding sleeve is movably connected to the surface of the fixing rod through a movable bearing. A blanking pipe is communicated with the bottom of the sliding sleeve. A mating arc-shaped shell is communicated with the bottom of the blanking pipe. Micropores are formed at the bottom of the mating arc-shaped shell.

[0009] Preferably, an oil inlet pipe is communicated with the top of the sliding sleeve. A dust-proof cover is threadedly sleeved on the top surface of the oil inlet pipe.

[0010] Preferably, auxiliary sliding teeth for cooperating with the driving gear are welded to the tops of both sides of the track body. Driving gears are welded to both sides of the traveling wheels. A connecting bearing is connected to the side of the driving gear away from the traveling wheel by bolts, and a transmission connecting rod is welded to the side of the connecting bearing away from the driving gear.

[0011] Preferably, a track support frame is welded to the bottom of the track body, and fixing bolts penetrate through both sides of the top of the track support frame.

[0012] Preferably, oil seepage holes are formed on both sides of the surface of the traveling wheel. A sealing plate is connected to the top of the traveling wheel through a sealing bolt, and an observation mirror is installed through the top of the sealing plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] A traveling mechanism of a sewage plant sludge scraping and sucking machine provided by the utility model is provided with traveling teeth meshing with each other on the surfaces of the traveling wheels and the track. During the traveling process of the device, the traveling teeth will be guided by meshing with each other, thereby improving the moving stability of the main body.

[0015] During the use of the device, the lubricating oil filled inside can be evenly dripped out, and the surfaces of the driving gear and the auxiliary sliding teeth are lubricated by attaching to them, thereby improving the connection lubricity during the meshing process of the driving gear and the auxiliary sliding teeth, so as to ensure that the moving heat wear between the driving gear and the auxiliary sliding teeth is reduced during the movement of the traveling wheel, thereby improving their service life.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As shown in Figure 1 the figure, a traveling mechanism of a sewage plant sludge scraper and suction machine includes a slide rail mechanism 1. The slide rail mechanism 1 includes a rail main body 2. A traveling mechanism 19 is arranged on the top of the rail main body 2. The traveling mechanism 19 includes traveling wheels 7. A lubrication mechanism 18 is arranged in the inner cavity of the traveling wheels 7. The lubrication mechanism 18 includes a fixing rod 12. One side of the fixing rod 12 close to the inner wall of the traveling wheel 7 is welded to the inner wall of the traveling wheel 7.

[0022] During use, the user opens the sealing plate 8, then unscrews the dust-proof cover, drips a certain amount of lubricating oil into the oil inlet pipe 17. The driving gear 10 will drive the traveling wheel 7 to rotate by meshing with the auxiliary sliding tooth 5, thereby improving the moving stability between them. At the same time, the weighing arc shell 15 will, under the action of gravity, always be close to the lower wall of the traveling wheel 7 in the inner cavity of the traveling wheel 7. Thus, the lubricating oil inside it will seep out under the action of gravity according to the aperture size of the micropores 14, and then uniformly seep out to both sides of the traveling wheel 7 through the oil seepage holes 9 opened on the surface of the traveling wheel 7 and adhere to the surface of the driving gear 10. When the driving gear 10 comes into contact and meshes with the auxiliary sliding tooth 5, it can prevent the lubricating oil from lubricating between the driving gear 10 and the auxiliary sliding tooth 5, thereby achieving the effect of reducing thermal wear and extending the service life of the corresponding driving gear 10 and auxiliary sliding tooth 5.

[0023] As a preferred embodiment of the present invention, as shown in Figure 3 the figure, a sliding sleeve 16 is movably connected to the surface of the fixing rod 12 through a movable bearing. A blanking pipe 13 is communicated with the bottom of the sliding sleeve 16. A weighing arc shell 15 is communicated with the bottom of the blanking pipe 13. Micropores 14 are opened at the bottom of the weighing arc shell 15.

[0024] This embodiment is to set a lubricating oil titration device in the inner cavity of the traveling wheel 7 so that it can perform slow lubricating oil titration during the movement of the traveling wheel 7.

[0025] In some embodiments, as shown in Figure 3 the figure, an oil inlet pipe 17 is communicated with the top of the sliding sleeve 16. A dust-proof cover is threadedly sleeved on the top surface of the oil inlet pipe 17.

[0026] This embodiment ensures the sealing performance of the oil inlet pipe 17 during the movement of the traveling wheel 7, thereby intercepting external dust and impurities.

[0027] In some embodiments, as Figure 1 shown, auxiliary sliding teeth 5 that cooperate with the driving gear 10 are welded to the tops of both sides of the track body 2. Driving gears 10 are welded to both sides of the traveling wheels 7. A connecting bearing 6 is connected to the side of the driving gear 10 away from the traveling wheel 7 by bolts, and a transmission connecting rod 11 is welded to the side of the connecting bearing 6 away from the driving gear 10.

[0028] This embodiment mainly considers connecting the device to an external speed reducer during use, thereby ensuring the external driving force during its movement.

[0029] In some embodiments, as Figure 1 shown, track support frames 3 are welded to the bottom of the track body 2, and fixing bolts 4 penetrate through both sides of the top of the track support frames 3.

[0030] This embodiment mainly considers positioning the track body 2 by fixedly installing the fixing bolts 4 and the track support frames 3 during the use of the device, so as to ensure the installation stability of its main body.

[0031] In some embodiments, as Figure 2 shown, oil leakage holes 9 are provided on both sides of the surface of the traveling wheel 7. A sealing plate 8 is connected to the top of the traveling wheel 7 by a sealing bolt, and an observation mirror is installed through the top of the sealing plate 8.

[0032] This embodiment mainly considers ensuring the sealing effect of the inner cavity of the traveling wheel 7 through the sealing plate 8 during the use of the device, and also facilitating the user to inject lubricating oil into the inner cavity of the inlet pipe 17.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
