Description

Technical Field

[0001] This utility model relates to the field of heavy machinery technology, and more specifically, to an auxiliary device for replacing the bearings of the traveling wheels of heavy equipment. Background Technology

[0002] When replacing the wheel bearings of heavy mobile equipment weighing up to 1100 tons, there are no corresponding lifting equipment or lifting points at the work site. Furthermore, because the heavy mobile equipment is relatively close to its track, there are no suitable locations for jacks. The only option is to disassemble the entire vehicle, replace the bearings, and then reassemble it, resulting in a long construction period and relatively low efficiency. Utility Model Content

[0003] The problem this invention addresses is: how to improve the efficiency of replacing bearings on the traveling wheels of heavy equipment.

[0004] To solve the above problems, this utility model provides an auxiliary device for replacing the bearings of the traveling wheels of heavy equipment, including a wedge block and a pad block. The wedge block is used to be installed on the track so that the traveling wheel moves upward along the wedge surface of the wedge block and disengages from the track. The pad block is used to be installed on the track, and the height of the pad block is greater than the height of the wedge block. The pad block is used to support the bottom of the heavy equipment before the traveling wheel moves downward along the wedge surface to contact the track.

[0005] Optionally, it also includes a guard plate, which corresponds one-to-one with the pad block. Each guard plate is located at the outer end of the corresponding pad block near the track. One end of the guard plate is connected to the top of the pad block, and the other end extends vertically away from the pad block. The guard plate and the top of the corresponding pad block form a limiting groove, which is used to position the bottom of the heavy equipment.

[0006] Optionally, the bottom of the pad is provided with an anti-slip structure for contacting the track.

[0007] Optionally, a rubber pad is provided on the top of the pad, and the rubber pad abuts against the bottom of the heavy equipment.

[0008] Optionally, the bottom of the pad is provided with a slot for penetrating the pad along the extension direction of the track and for engaging with the track.

[0009] Optionally, the pad block is further provided with a stop bar, which is distributed along the extension direction of the track and is used to provide diagonal support between the pad block and the track.

[0010] Optionally, the bottom of the wedge block is provided with a positioning groove, which is used to penetrate the wedge block along the extension direction of the track and to engage with the track.

[0011] Optionally, the side of the wedge block also includes a limiting plate, which is used to diagonally support the wedge block and the track.

[0012] Optionally, the top of the wedge block is further provided with a planar structure, which is used to stop the traveling wheel.

[0013] Optionally, the planar structure may also be provided with protrusions for restricting the movement of the walking wheels.

[0014] Compared with related technologies, the auxiliary device for replacing the bearings of the traveling wheels of heavy equipment in this utility model utilizes a wedge block installed on the track. The traveling wheel can move upward along the wedge surface of the wedge block, allowing it to detach from the track and thus raise the entire heavy equipment. This ensures sufficient working space between the bottom of the heavy equipment and the track, facilitating the installation of a pad on the track. Since the height of the pad is greater than that of the wedge block, it supports the bottom of the heavy equipment after the traveling wheel moves downward along the wedge surface. Furthermore, because the height of the pad is greater than the distance between the bottom of the heavy equipment and the track when it is on the track, the traveling wheel contacts the pad before moving downward to contact the track. Therefore, the pad supports the heavy equipment, keeping the traveling wheel suspended in the air. This allows for the replacement of the traveling wheel bearings individually without disassembling the entire vehicle, thereby improving the efficiency of replacing the bearings of the traveling wheels of heavy equipment.

Therefore, they should not be construed as limitations on the invention.

[0022] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.

[0023] Combination Figure 1 As shown, this utility model embodiment provides an auxiliary device for replacing the bearing of a heavy equipment traveling wheel, including a wedge block 1 and a pad block 2. The wedge block 1 is used to be installed on the track so that the traveling wheel 8 moves upward along the wedge surface 11 of the wedge block 1 and disengages from the track. The pad block 2 is used to be installed on the track, and the height of the pad block 2 is greater than the height of the wedge block 1. The pad block 2 is used to support the bottom of the heavy equipment before the traveling wheel 8 moves downward along the wedge surface 11 to contact the track.

[0024] Specifically, an example is given using a wheel 8 of heavy equipment. Figure 1 As shown in Figure a, the traveling wheel 8 of the heavy equipment rolls on the track 9. When it is necessary to replace the bearing of the traveling wheel 8, first install the wedge block 1 on the track 9, as shown in Figure a. Figure 1 As shown in b, the traveling wheel 8 moves upward along the wedge surface 11 of the wedge block 1 via the drive device of the heavy equipment, causing the traveling wheel 8 to disengage from the track 9. When the traveling wheel 8 reaches the highest position of the wedge block 1, as shown in b. Figure 1 As shown in c, install pad 2 on track 98. Pad 2 is located between track 9 and the bottom of the heavy equipment. Then, as shown in c. Figure 1As shown in d, the traveling wheel 8 moves downward along the wedge surface 11 of the wedge block 1 again, so that the bottom of the heavy equipment can abut against the top of the pad block 2. The pad block 2 supports the heavy equipment, so that the traveling wheel 8 is suspended above the track 9, so that the bearing of each traveling wheel 8 can be replaced individually without disassembling the whole vehicle. It can be understood that the number of pad blocks 2 can be adjusted adaptively along the extension direction of the track 9, and the height of each pad block 2 is higher than the maximum height of the wedge block 1. Furthermore, the height of each pad block 2 is greater than the distance (or height difference) between the bottom of the heavy equipment and the track 9 when the heavy equipment is located on the track 9.

[0025] Therefore, in this embodiment, the wedge block 1 is used to install on the track 9. The traveling wheel 8 can move upward along the wedge surface 11 of the wedge block 1, so that the traveling wheel 8 can be separated from the track 9 to achieve overall lifting of the heavy equipment. This ensures that there is enough working space between the bottom of the heavy equipment and the track 9 to facilitate the installation of the pad block 2 on the track 9. Furthermore, since the height of the pad block 2 is greater than the height of the wedge block 1, it can support the bottom of the heavy equipment after the traveling wheel 8 moves downward along the wedge surface 11. Moreover, since the height of the pad block 2 is greater than the distance between the bottom of the heavy equipment and the track 9 when the heavy equipment is on the track 9, that is, the traveling wheel 8 contacts the pad block 2 before moving downward to contact the track 9. Therefore, the pad block 2 can support the heavy equipment and keep the traveling wheel 8 suspended. This allows the bearing of the traveling wheel 8 to be replaced separately without disassembling the entire vehicle, thereby improving the work efficiency of replacing the bearing of the traveling wheel of the heavy equipment.

[0026] It should be noted that when the pad 2 supports the heavy equipment to keep the traveling wheel 8 suspended, the wedge block 1 can be removed. Even if the wedge block 1 is not removed, since the weight of the entire heavy equipment is mainly supported by the pad 2, the interaction force between the heavy equipment and the wedge block 1 is small, and it is also convenient to replace the bearing of the traveling wheel of the heavy equipment.

[0027] Optionally, combined Figure 3 As shown, it also includes a guard plate 3, which corresponds one-to-one with the pad block 2. Each guard plate 3 is located at the outer end of the corresponding pad block 2 near the track. One end of the guard plate 3 is connected to the top of the pad block 2, and the other end extends vertically away from the pad block 2. The guard plate 3 and the top of the corresponding pad block 2 form a limiting groove, which is used to position the bottom of the heavy equipment.

[0028] Specifically, the heavy equipment travels on two tracks 9. When replacing the bearings of the traveling wheels of the heavy equipment, a pad 2 needs to be installed on each track 9 for support. In the width direction of the track 9, the guard plate 3 is located at the end of the pad 2 away from the other track 9 and is connected to the top of the pad 2 by a threaded connector. A limiting groove is formed between the guard plate 3 and the top of the pad 2. After the traveling wheel 8 moves downward along the wedge surface 11, the bottom of the heavy equipment can be locked in the limiting groove of the pad 2 of the two tracks 9, ensuring the verticality of the heavy equipment before and after the traveling wheel 8 moves, thereby preventing the heavy equipment from deviating from the track 9 and causing it to tip over, thus improving operational safety.

[0029] Optionally, the bottom of the pad 2 is provided with an anti-slip structure for contacting the track 9.

[0030] Specifically, the anti-slip structure can be anti-slip textures, anti-slip pads, or other equivalent structures with anti-slip properties. Thus, by utilizing the anti-slip structure located between the bottom of the pad 2 and the track 9, the friction between the bottom of the pad 2 and the track 9 can be increased, ensuring the stability of the pad 2 on the track 9, and consequently ensuring the stability of heavy equipment when it is placed on the pad 2.

[0031] Optionally, a rubber pad is provided on the top of the pad 2, and the rubber pad abuts against the bottom of the heavy equipment.

[0032] Specifically, the rubber pad is installed on the top of the pad block 2 through a threaded connector. When the traveling wheel 8 moves downward along the wedge surface 11, the bottom of the heavy equipment can come into contact with the rubber pad. The rubber pad can achieve soft contact between the bottom of the heavy equipment and the top of the pad block 2, ensuring the stability of the heavy equipment on the pad block 2 while avoiding wear between the pad block 2 and the bottom of the heavy equipment, thereby protecting the heavy equipment.

[0033] Optionally, combined Figure 3 As shown, the bottom of the pad 2 is provided with a slot 4, which is used to pass through the pad 2 along the extension direction of the track 9 and to engage with the track 9. The anti-slip structure mentioned above is installed at the bottom of the slot 4.

[0034] Specifically, the slot 4 is located at the bottom of the pad 2, with the slot opening facing downwards. The slot 4 extends through the pad 2 along the extension direction of the track 9, and the pad 2 is secured to the track 9 by the slot 4. In this way, the slot 4 allows the pad 2 to be quickly installed on the track 9 and can limit the pad 2 in the width direction of the track 9 to ensure the stability of the pad 2 in use.

[0035] Optionally, combined Figure 3 As shown, a stop bar 5 is also provided on the pad block 2. The stop bar 5 is distributed along the extension direction of the track 9 and is used to provide diagonal support between the pad block 2 and the track 9.

[0036] Specifically, two stop rods 5 are provided, symmetrical about the pad 2 along the extension direction of the track 9. The two stop rods 5 are diagonally supported between the pad 2 and the track 9. That is, one end of each stop rod 5 facing the pad 2 is connected to the pad 2, and the other end of each stop rod 5 facing the track 9 is connected to the track 9. For example, the end of the stop rod 5 facing the track 9 is connected to the track 9 via a claw. When the pad 2 moves in the extension direction of the track 9, the stop rods 5 can impede the movement of the pad 2, ensuring the stability of the pad 2 and thus ensuring safe use.

[0037] Optionally, combined Figure 2 As shown, a positioning groove 6 is provided at the bottom of the wedge block 1. The positioning groove 6 is used to penetrate the wedge block 1 along the extension direction of the track 9 and to engage with the track 9.

[0038] Specifically, the positioning groove 6 is located at the bottom of the wedge block 1, with the opening of the positioning groove 6 facing downwards. The positioning groove 6 is used to penetrate the wedge block 1 along the extension direction of the track 9, and the wedge block 1 is secured to the track 9 through the positioning groove 6. In this way, the wedge block 1 can be positioned by the positioning groove 6 to quickly install the wedge block 1 on the track 9.

[0039] Optionally, combined Figure 2 As shown, the side of the wedge block 1 also includes a limiting plate 7, which is used to provide diagonal support between the wedge block 1 and the track 9.

[0040] Specifically, the side of wedge block 1 refers to the side of wedge block 1 facing away from wedge surface 11. The limiting plate 7 is located on the side of wedge block 1 facing away from wedge surface 11, and the limiting plate 7 is diagonally supported between wedge block 1 and track 9. That is, the end of the limiting plate 7 facing wedge block 1 is connected to the wedge block, and the end of the limiting plate 7 facing track 9 is connected to track 9. For example, the end of the limiting plate 7 facing track 9 is connected to track 9 via a chuck. When wedge block 1 moves towards the limiting plate 7, track 9, through the limiting plate 7, hinders the movement of wedge block 1 to ensure the stability of wedge block 1 during use.

[0041] Optionally, combined Figure 2 As shown, a planar structure 12 is also provided on the top of the wedge block 1, which is used to stop the traveling wheel 8.

[0042] Specifically, the planar structure 12 is located on top of the wedge block 1, and the planar structure 12 is aligned with the top of the wedge surface 11. After the traveling wheel 8 travels along the wedge surface 11 to the planar structure 12, it can stop on the planar structure 12 to allow sufficient time for the pad block 2 to be installed on the track 9, thereby ensuring operational safety.

[0043] Optionally, combined Figure 2 As shown, the planar structure 12 is also provided with a protrusion 13 for restricting the movement of the walking wheel 8.

[0044] Specifically, the protrusion 13 is perpendicular to the planar structure 12 and is located at the end of the planar structure 12 away from the wedge-shaped surface 11. After the traveling wheel 8 moves onto the planar structure 12, the protrusion 13 abuts against the traveling wheel 8, and the protrusion 13 hinders the continued movement of the traveling wheel 8, preventing the traveling wheel 8 from slipping off the wedge-shaped block 1, so as to ensure operational safety.

[0045] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
