Description

Technical Field

[0001] This utility model relates to the field of tower wheel technology, specifically a combined tower wheel. Background Technology

[0002] Tower wheels typically consist of multiple stepped wheel bodies. A search revealed a Chinese utility model patent with publication number CN201493328U, which discloses a modular tower wheel. According to its description, it mainly includes an outer wheel disc, an inner wheel disc, a large pressure plate, a small pressure plate, and a wear-resistant ring. The components are mainly connected by fasteners or keys, resulting in a simple structure and convenient assembly. The components are disassembled to reduce weight, facilitating installation and disassembly, reducing labor intensity, and improving work efficiency.

[0003] However, the tow wheel in the above patent has the following defects: after working for a long time, the wheel disc is prone to overheating and is difficult to dissipate heat in time, thus affecting the service life of the tow wheel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a combined tower wheel to solve the problem mentioned in the background art that the tower wheel does not have self-heating capabilities.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A combined turret wheel includes a hub and at least two I-shaped rims connected to the hub by screws. The hub has an internal spline for connecting a drive shaft. One end of the hub has a mounting part with threads on its outer wall, and a self-blowing device is connected to the mounting part via the threads. The side wall of the hub has an air supply pipe communicating with the outside. A wear-resistant ring is fitted inside the rims. The rims have multiple radial ventilation holes, one end of which connects to the outlet of the air supply pipe, and the other end of which communicates with the inner side of the rim.

[0007] Preferably, the self-blowing device includes an annular housing, a connecting sleeve at the lower part of the housing, the connecting sleeve being threadedly connected to the mounting part, multiple fans being equidistantly distributed along the axis inside the housing, a shaft being rotatably connected to the center of each fan, the lower end of the shaft being fixedly connected to the bottom of the housing, an annular dust cover being fixed to the top of the housing, multiple connecting blocks distributed along the axis and matching the shaft being provided on the dust cover, the upper end of the shaft being fixedly connected to the corresponding connecting block, and multiple air outlets being provided at the bottom of the housing.

[0008] In the above technical solution, when the tower wheel rotates, it will drive the housing to rotate as well, thereby causing all the fans inside the housing to rotate together. When the fans rotate, the air they generate flows out through the air outlet.

[0009] Preferably, the air supply duct includes multiple axial first channels and radial second channels. The first channels correspond one-to-one with the air outlets, and the upper end of the first channel is connected to the corresponding air outlet. The second channels correspond one-to-one with the wheel rims, and one end of the second channel is connected to the first channel, while the other end of the second channel is connected to the ventilation hole on the corresponding wheel rim.

[0010] In the above technical solution, the air blown out by the fan enters the first channel through the air outlet, then enters the second channel through the first channel, and finally enters the wheel rim through the second channel, thereby achieving self-heating of the wheel rim.

[0011] Preferably, the outer wall of the wheel hub is provided with multiple circularly distributed first screw holes, with each two circles of first screw holes forming a group. The wheel rim is provided with second screw holes that match the two circles of first screw holes in the same group. The wheel rim is fixed to the wheel hub by the cooperation of screws, first screw holes, and second screw holes.

[0012] In the above technical solution, the wheel rim is fixed to the wheel hub with screws, making it convenient to replace wheel rims of different diameters.

[0013] Preferably, the hub has multiple grooves matching the ventilation holes between the two first screw holes in the same group, the pipe opening of the second channel is located in the groove, the diameter of the groove is larger than the diameter of the ventilation hole, and the ventilation hole corresponds to the corresponding groove.

[0014] In the above technical solution, due to the presence of the groove, and the diameter of the groove being larger than the diameter of the ventilation hole, the wheel hub will not block the ventilation hole on the wheel rim after the wheel rim is fixed on the hub. Instead, it leaves enough space for the ventilation hole so that wind energy can smoothly enter the ventilation hole through the second channel.

[0015] Preferably, the inner wall of the wear-resistant ring sleeve is provided with a plurality of slots, and the wheel rim is provided with teeth that match the slots. The wear-resistant ring sleeve is fixed in the wheel rim by the cooperation of the slots and teeth.

[0016] In the above technical solution, the wear-resistant ring sleeve plays a role in wear resistance. It is positioned by being engaged with the teeth of the wheel rim through a groove, which prevents the wear-resistant ring sleeve from rotating.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The self-blowing device is installed on the wheel hub. When the wheel hub rotates, it drives the self-blowing device to rotate synchronously. The air generated by the self-blowing device is sent to the ventilation hole of the wheel rim through the air supply pipe, and then sent into the wheel rim through the ventilation hole, thereby providing self-heating for the wheel rim and wear-resistant ring sleeve, improving the heat dissipation effect and extending the service life of the tower wheel.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-5 A modular tow wheel includes a hub 1 and at least two I-shaped rims 2 connected to the hub 1 by screws. The inner wall of the hub has internal splines for transmission connection with a drive shaft. Both the hub 1 and the rims 2 are made of 40Cr quenched and tempered steel. The diameter of the rims 2 increases from one end to the other, with the hub being 150-200mm long and 30-50mm in diameter. The outer wall of the hub 1 has multiple circularly distributed first screw holes 9, with every two circles of first screw holes forming a group. The two ends of the rims 2 have second screw holes 10 that match the two circles of first screw holes in the same group. The rims 2 are fixed to the hub 1 by screws, the first screw holes, and the second screw holes, thus facilitating the replacement of rims of different diameters.

[0028] One end of the hub 1 is provided with an integral mounting part 3. The diameter of the mounting part 3 is smaller than the diameter of the hub 1. The outer wall of the mounting part 3 is threaded, and a self-blowing device 4 is connected to it via the thread. The self-blowing device 4 can rotate with the hub and generate air. The side wall of the hub 1 is provided with an air supply pipe that communicates with the outside. A wear-resistant ring sleeve 5 is fitted inside the rim 2. The wear-resistant ring sleeve 5 is made of high-strength alloy steel. The rim 2 is provided with multiple radial ventilation holes 6. One end of the ventilation hole 6 is connected to the outlet of the air supply pipe, and the other end of the ventilation hole 6 is connected to the inner side of the rim 2.

[0029] like Figure 2 As shown, the self-blowing device 4 includes an annular housing 41, the inner diameter of which is the same as the inner diameter of the hub. An integral connecting sleeve 42 is provided at the lower part of the housing 41, and the inner wall of the connecting sleeve 42 has internal threads. The connecting sleeve 42 is threadedly connected to the mounting part 3. Multiple fans 43 are equidistantly distributed along the axis inside the housing 41. A shaft 44 is rotatably connected to the center of each fan 43 via a rotary bearing. The lower end of the shaft 44 is fixedly connected to the bottom of the housing 41. An annular dust cover 45 is fixed to the top of the housing 41. The dust cover 45 is mesh-like and has multiple connecting blocks 46 distributed along the axis and matching the shafts. The upper end of the shaft 44 is fixedly connected to the corresponding connecting block 46. Multiple air outlets 47 are also provided at the bottom of the housing 41. When the hub 1 rotates, it drives the housing 41 to rotate as well, causing all the fans 43 inside the housing 41 to rotate together. When the fans 43 rotate, the air they generate flows out through the air outlets 47. The housing, shafts, fans, and dust cover can all be made of plastic.

[0030] like Figure 5 As shown, the air supply duct includes multiple axial first channels 7 and radial second channels 8. Each first channel 7 corresponds to an air outlet 47, with its upper end connected to the corresponding air outlet 47. Each second channel 8 corresponds to a wheel rim 2, with one end connected to the first channel 7 and the other end connected to a ventilation hole 6 on the corresponding wheel rim. The air blown by the fan 43 enters the first channel 7 through the air outlet 47, then enters the second channel 8 through the first channel 7, and finally enters the wheel rim 2 through the second channel 8, thus achieving self-heating of the wheel rim 2.

[0031] like Figure 3 As shown, the hub 1 has multiple grooves 11 matching the ventilation holes 6 between the two first screw holes in the same group. The opening of the second channel 8 is located in the groove 11, and the diameter of the groove 11 is larger than the diameter of the ventilation hole 6. Due to the presence of the groove 11 and the fact that the diameter of the groove 11 is larger than the diameter of the ventilation hole 6, when the wheel rim 2 is fixed on the hub 1, the hub 1 will not block the ventilation hole 6 on the wheel rim 2, but will leave enough space for the ventilation hole 6 so that the air can smoothly enter the ventilation hole 6 through the second channel 8.

[0032] The working principle of this embodiment is as follows: the wheel rims are fixed on the hub in sequence, and the self-blowing device is installed on the mounting part. Then the hub is connected to the drive shaft. When the drive shaft rotates, it drives the hub 1 to rotate. The hub 1 drives the housing 41 to rotate together, so that all the fans 43 in the housing 41 rotate together. When the fan 43 rotates, the air generated by it flows out from the air outlet 47 and enters the first channel 7, then enters the second channel 8 from the first channel 7, and finally enters the wheel rim 2 from the second channel 8 and blows onto the wear-resistant ring 5, thereby realizing the self-heating of the wheel rim 2.

[0033] Example 2

[0034] Based on Embodiment 1, the inner wall of the wear-resistant ring sleeve 5 is provided with several slots 12, and the wheel rim 2 is provided with locking teeth 13 that match the slots. The wear-resistant ring sleeve 5 is fixed in the wheel rim 2 through the cooperation of the slots and locking teeth. The wear-resistant ring sleeve plays a role in wear resistance to protect the wheel rim. The wear-resistant ring sleeve is positioned by being locked onto the locking teeth of the wheel rim through the slots, preventing it from rotating.
