[0027] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0028] Please refer to Figure 1 The embodiment of the present application provides a traveling wheel assembly device, which is an improvement on the traveling wheel of the existing overhead crane, and is improved to a bearing assembly 120 based on the original bearing 121. During the use of the wheels of the existing overhead crane, the wheel rim contacts the side of the track during the operation of the trolley or the trolley, generating a horizontal lateral thrust, which causes frequent damage to the fastening bolts of the traveling crane body, and the track pressure plate bolts loosen by 5-15mm, and cause friction and wear between the wheel rim and the track, so that the horizontality of the wheel deviates; and the horizontality of the wheel is not easy to adjust, so that the two wheels on both sides of the large wheel are not synchronized, and can only be stopped for maintenance and replacement, affecting the production progress. Therefore, the present application improves the wheel structure and designs a wheel assembly device, which can adjust the horizontality of the wheel in time after the wheel rim causes friction and wear to ensure stable production.

[0029] Please refer to Figure 2 The trolley wheel assembly device 100 includes: a wheel axle 110 and a bearing assembly 120. The wheel axle 110 serves as a connection base for the wheel, and is used to provide a first mounting position 111 and a second mounting position 112 for the trolley wheel, as well as a mounting position for the overhead crane wheel 130. The wheel axle 110 is made of 45# steel, and is positioned and connected by a flat key. The wheel axle 110 is connected to the overhead crane wheel 130 and the bearing assembly 120, and the wheel axle 110 and the overhead crane wheel 130 are interference fit. The bearing assemblies 120 are arranged on both sides of the overhead crane wheel 130; wherein the first mounting position 111 and the second mounting position 112 are respectively mounted with small wheels, and are respectively located on both sides of the overhead crane wheel 130; the bearing assemblies 120 are respectively mounted on the first mounting position 111 and the second mounting position 112, and the wheel seat 140 is mounted on the bearing assembly 120, and the wheel is fixed on the wheel seat 140. The bearing assembly 120 includes a bearing 121 , a bearing sleeve 122 and a washer 126 . The first installation position 111 and the second installation position 112 are respectively connected with the bearing 121 by shaft sleeves.

[0030] The two bearings 121 are symmetrically arranged about the overhead crane wheel 130. The bearing 121 adopts a spherical roller bearing 121. The bearing sleeve 122 is connected to the bearing 121 in the circumferential direction by a sleeve arrangement. The bearing sleeve 122 adopts a material of ZG270-500 and is used for radial positioning of the bearing 121. In this way, a double-layer sleeve arrangement structure is formed. The inner edge of the wheel seat 140 is installed on the circumferential outer side surface of the bearing sleeve 122 to form a whole. The washer 126 is arranged between the wheel seat 140 and the bearing sleeve 122 corresponding to at least one of the first installation position 111 and the second installation position 112, that is, the washer 126 is arranged on the contact surface of the wheel seat 140 and the bearing sleeve 122. The washer 126 The material of kraft paper or other thinner materials can be used. When the levelness of the wheel is not good, a washer 126 can be set. The washer 126 can be selected with different thickness specifications as needed. By adjusting the thickness of the washer 126 corresponding to the first mounting position 111 or the second mounting position 112, the relative deviation position of the wheel seat 140 corresponding to the first mounting position 111 or the second mounting position 112 can be changed. Since the wheel seat 140 located at the first mounting position 111 or the second mounting position 112 is slightly low after the levelness deviation, the wheel seat 140 is relatively raised after the washer 126 is set to keep the two wheel seats 140 at the same height to adjust the levelness of driving.

[0031] The present application replaces the original bearing 121 structure with a bearing 121 and a bearing sleeve 122, thereby adding a layer of structure to the outer periphery of the wheel shaft 110. Due to the addition of the bearing sleeve 122, it is convenient to adjust the distance between the bearing 121 and the wheel seat 140. By introducing the washer 126, when the levelness deviates, the washer 126 can supplement the deviated part, so that the position of the wheel seat 140 at the first mounting position 111 and the second mounting position 112 can be readjusted. Through the thickness of the washer 126, it can adapt to the deviated position and readjust the two wheel seats 140 to the original position. In this way, the problem of adjusting the levelness of the crown crane wheel 130 can be solved. After the problem occurs, the levelness of the crown crane wheel 130 can be adjusted to a better state in time, so as to keep the wheels on both sides of the crown crane running synchronously, maintain the smooth operation of the crown crane, and reduce the safety risks caused by abnormal operation. The cost of overhead crane wheel 130 is 30,000 to 40,000 yuan. The production line stops abnormally three times a year on average due to horizontal deviation of overhead crane wheel 130, with a direct economic loss of 500,000 yuan. After adopting this application, the scrapping of single wheel rim can be handled in time, and the scrapping of double wheel rim can double the service life of the wheel to four years and 30,000 yuan, saving 10,000 to 20,000 yuan in economic benefits each year. Each vehicle has 8 wheels and saves 160,000 yuan per vehicle each year, totaling 660,000 yuan.
