Description

Technical Field

[0001] The utility model relates to the technical field of electric tugboats, in particular to a driving wheel for electric tugboats. Background Art

[0002] An electric tugboat, also called an electric support wheel, is used to be installed on a loading platform to move heavy objects. It is mainly composed of a support and wheels, and is also equipped with a drive motor, so that the tugboat can be driven to rotate after being powered on, which can save manpower and the time required to move heavy objects.

[0003] However, the driving wheel of the existing electric tugboat is composed of a tire and a wheel hub, and when the tire and the wheel hub are disassembled, additional tools are needed to separate the tire from the outer side of the wheel hub, which is not conducive to the rapid disassembly and assembly of the tire and the wheel hub, resulting in troublesome and time-consuming replacement of severely worn tires; in addition, the driving wheel of the existing electric tugboat is driven to rotate by a driving motor, so that the torque force generated by the driving force directly acts on the tire. Compared with the traditional traction drive, it is easier for foreign objects to get stuck in the tread groove of the tire tread of the wheel. If the foreign objects in the tread groove are not cleaned in time, it is easy to affect the normal rolling of the tire. Utility Model Content

[0004] The purpose of the utility model is to provide a driving wheel for an electric tugboat to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a driving wheel for an electric tugboat, comprising a clamping ring, an outer wall of the clamping ring is sleeved with an outer tire, a hub is arranged inside the clamping ring, a circular plate is arranged on one side of the hub, a clamping plate is fixedly connected to one side wall of the circular plate, a scraper is fixedly connected to the bottom of one side wall of the clamping plate, a sponge pad is fixedly connected to the middle part of one side wall of the clamping plate, a turntable is arranged on the other side of the hub, a plurality of clamping teeth are fixedly connected to the outer wall of the turntable and the hub, a cross bar is movably penetrated through the middle part of the hub, and a sleeve is fixedly connected to the middle part of the turntable.

[0006] Preferably, a torsion plate is fixedly connected to the middle of the circular plate, the circular plate is movably connected to the cross bar by a threaded sleeve, and the circular plate is movably connected to the clamping ring via the cross bar.

[0007] Preferably, a sliding groove is provided on the outer wall of the cross bar away from the circular plate, and a clamping block is slidably connected to the inner wall of the sliding groove.

[0008] Preferably, the clamping block is fixedly connected to the sleeve, and the sleeve is movably connected to the cross bar via the clamping block.

[0009] Preferably, a groove is formed at one end of the cross bar, and a spring is movably connected to the inner wall of the groove.

[0010] Preferably, one end of the spring is fixedly connected to the inner wall of the sleeve, and the turntable is movably connected to the wheel hub via the sleeve and the spring.

[0011] Preferably, the wheel hub is movably connected to the clamping ring via clamping teeth, a rotating disk and a circular plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The driving wheel of the electric tugboat is used for a turntable, a clamping tooth, a sleeve and a cross bar. When the clamping tooth on the turntable is adjusted to coincide with the clamping tooth on the wheel hub, one side of the wheel hub can be drawn out from the inside of the clamping ring, so that the wheel hub and the outer tire can be quickly separated, avoiding the use of additional tools to separate the wheel hub from the outer tire, thereby saving the time for separating the outer tire from the wheel hub and shortening the time for replacing a severely worn outer tire.

[0014] 2. The driving wheel of the electric tugboat uses a card plate, a sponge pad and a scraper to ensure that when the driving wheel of the electric tugboat is driven by a motor and rolls on the ground, foreign objects stuck in the tread groove of the outer wall of the driving wheel can be cleaned in time by the scraper on the card plate and the sponge pad, so that the tread of the driving wheel remains clean and tidy, thereby reducing the adverse effect on the normal rolling of the outer tire of the driving wheel.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, this embodiment is used for the driving wheel of the electric tugboat, including a snap ring 2, the outer wall of the snap ring 2 is sleeved with an outer tire 1, the interior of the snap ring 2 is provided with a hub 3, one side of the hub 3 is provided with a circular plate 8, one side wall of the circular plate 8 is fixedly connected with a clamping plate 4, the bottom of one side wall of the clamping plate 4 is fixedly connected with a scraper 12, the middle part of one side wall of the clamping plate 4 is fixedly connected with a sponge pad 11, the other side of the hub 3 is provided with a turntable 5, the outer wall of the turntable 5 and the hub 3 are fixedly connected with a plurality of clamping teeth 13, the middle part of the hub 3 is movably penetrated with a cross bar 16, and the middle part of the turntable 5 is fixedly connected with a sleeve 6.

[0024] Specifically, the inner wall of the snap ring 2 is provided with a plurality of embedding grooves, so that the latch teeth 13 on the wheel hub 3 can be embedded in the embedding grooves, thereby realizing the snap-fit ​​fixation of the wheel hub 3 with the snap ring 2 and the outer wall of the snap ring 2, and the outer tire 1. The outer tire 1 is made of wear-resistant rubber material, and the surface is provided with pattern grooves for anti-skid. The wheel hub 3 is a solid structure, so that when the force of the outer tire 1 is transmitted to the wheel hub 3, the wheel hub 3 is not easy to deform. The function of the circular plate 8 is to enable one end of the cross bar 16 to be temporarily fixed to one side of the driving wheel, so as to facilitate the sleeve 6 to be pulled along the other end of the cross bar 16. The cross section of the card plate 4 is "L"-shaped, so that the sponge pad 11 and the scraper 12 on the inner wall of the card plate 4 can maintain a state of being in close contact with the tread of the outer tire 1, so that the scraper 12 can timely clean foreign objects stuck in the tread, and the scraper 1 2 can scrape off foreign matter on the tread of the outer tire 1, and the sponge pad 11 can wipe the particles remaining after scraping off the foreign matter, so that the tread of the outer tire 1 remains clean and tidy. The diameter of the turntable 5 is the same as the diameter of the wheel hub 3, so that when the latch teeth 13 on the turntable 5 are rotated to coincide with the latch teeth 13 on the wheel hub 3, the turntable 5 can be simultaneously withdrawn from one side of the snap ring 2 with the wheel hub 3, thereby realizing the rapid separation of the wheel hub 3 and the outer tire 1, and facilitating the replacement of the outer tire 1 that is severely worn. The function of the cross bar 16 is to connect the circular plate 8 and the turntable 5, so that the circular plate 8 and the turntable 5 can limit the wheel hub 3 in the snap ring 2, thereby facilitating the maintenance of the connection state between the wheel hub 3 and the outer tire 1. The inner diameter of the sleeve 6 is adapted to the outer diameter of the cross bar 16, so that the sleeve 6 can rotate and slide along the end of the cross bar 16.

[0025] Furthermore, a torsion plate 7 is fixedly connected to the middle of the circular plate 8, and the circular plate 8 is movably connected to the cross bar 16 by a threaded sleeve. The circular plate 8 is movably connected to the clamping ring 2 through the cross bar 16, and the function of the torsion plate 7 is to facilitate unscrewing the circular plate 8 from the end of the cross bar 16.

[0026] Furthermore, a slide groove 10 is provided on the outer wall of the cross bar 16 away from the circular plate 8, and a block 9 is slidably connected to the inner wall of the slide groove 10. The shape of the slide groove 10 is "U-shaped", so that the block 9 can slide smoothly along the outer wall of the cross bar 16 and drive the sleeve 6 and the turntable 5 to adjust the position.

[0027] Furthermore, the block 9 is fixedly connected to the sleeve 6, and the sleeve 6 is movably connected to the cross bar 16 through the block 9. The sleeve 6 can slide along the slide groove 10 through the block 9, so that the sleeve 6 can drive the latch teeth 13 on the turntable 5 to adjust to a position that coincides with the latch teeth 13 on the wheel hub 3, thereby realizing the removal of the wheel hub 3 from the retaining ring 2 and the separation of the wheel hub 3 and the outer tire 1.

[0028] Furthermore, a groove 14 is formed at one end of the cross bar 16 , and a spring 15 is movably connected to the inner wall of the groove 14 . The groove 14 serves to hide the stretched spring 15 to reduce the interference of the spring 15 on the sleeve 6 .

[0029] Furthermore, one end of the spring 15 is fixedly connected to the inner wall of the sleeve 6, and the turntable 5 is movably connected to the wheel hub 3 through the sleeve 6 and the spring 15. The spring 15 will be elongated and twisted when the sleeve 6 slides along the slide groove 10 through the block 9. After the sleeve 6 is not pulled by external force, the spring 15 will be deformed and re-sleeved on the end of the cross bar 16, so that the turntable 5 fits onto the wheel hub 3 again.

[0030] Furthermore, the wheel hub 3 is movably connected to the retaining ring 2 through the latch teeth 13, the turntable 5 and the circular plate 8. When the turntable 5 is in the initial state, the latch teeth 13 on the turntable 5 and the latch teeth 13 on the wheel hub 3 will be in a misaligned state. At the same time, the latch teeth 13 on the turntable 5 will fit the side wall of the retaining ring 2, and the circular plate 8 will also fit the other side wall of the retaining ring 2, so that the wheel hub 3 is clamped and fixed on the retaining ring 2.

[0031] The method of using the present embodiment is as follows: when the driving wheel for the electric tugboat is used, the wheel hub 3 will be connected to the driving motor through the transmission mechanism, at which time the wheel hub 3 will drive the snap ring 2 and the outer tire 1 outside the snap ring 2 to rotate, so that the outer tire 1 rolls in contact with the ground, and at the same time, the scraper 12 and the sponge pad 11 on the card plate 4 will contact the tread of the outer tire 1 in turn under the support of the cross bar 16 and the circular plate 8, and foreign objects stuck in the tread groove on the surface of the outer tire 1 will be cleaned in time. When the outer tire 1 with severe wear needs to be replaced, the sleeve 6 can be pulled outward first, so that the sleeve 6 slides along the end of the cross bar 16, so that the spring 1 in the groove 14 can be 5 is stretched, and the block 9 on the inner wall of the sleeve 6 will slide along the slide groove 10 on the cross bar 16. When the block 9 slides to the other end of the slide groove 10, the sleeve 6 is released, so that the stretched spring 15 pulls the sleeve 6 back to the end of the cross bar 16 through the elastic force generated by the deformation. At this time, the sleeve 6 will drive the turntable 5 to stick to the side wall of the wheel hub 3 again, and the latch teeth 13 on the turntable 5 will overlap with the latch teeth 13 on the wheel hub 3, so that the turntable 5 is separated from the snap ring 2, and then the wheel hub 3 and the turntable 5 can be pulled out from the inner side of the snap ring 2, and at the same time drive the card plate 4 to separate from the outer tire 1, so that the wheel hub 3 and the outer tire 1 can be quickly separated, and then the new outer tire 1 can be replaced.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
