Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, and in particular to a guide wheel for special engineering equipment. Background Technology

[0002] Guide wheels are used in special engineering equipment, such as mining machinery and large-scale cutting equipment for reinforced concrete in construction sites, bridges, and tunnels. Diamond cables are wound around the guide wheels, which drive the diamond cables to rotate and achieve cutting. These guide wheels are in harsh working environments (high dust, high humidity, and high radial force) for a long time. Dust and moisture can easily enter the guide wheels, affecting the smoothness of the internal bearings. In addition, the large radial force on the guide wheels can easily cause the positions of multiple bearings to change, making it impossible to maintain good operating clearance. The bearings wear out quickly and become less durable, resulting in a short service life for the guide wheels. Furthermore, the encapsulation structure of the bearings inside the guide wheels is difficult to remove, making it difficult to replace the bearings when they are severely worn, which is inconvenient for maintenance.

[0040] refer to Figure 1-4 An embodiment of this utility model shows a guide wheel for special engineering equipment, including a support assembly 1, a guide wheel frame 2, at least two bearings 3, two frame oil seals 4, multiple separators 5, and a rubber wheel 6;

[0041] The support assembly 1 includes a support shaft section 113. The guide wheel frame 2 is provided with a first central hole 21 arranged along its axial direction. The guide wheel frame 2 is rotatably sleeved on the support shaft section 113. The bearing 3 is disposed between the first central hole 21 and the support shaft section 113. Two frame oil seals 4 are respectively disposed at both ends of the first central hole 21. The separator 5 is disposed between two adjacent bearings 3 and between the bearing 3 and the frame oil seal 4. The rubber wheel 6 is provided with a second central hole 61 arranged along its axial direction. The rubber wheel 6 is fixedly sleeved on the guide wheel frame 2.

[0042] Among them, such as Figure 3 As shown, the guide wheel of this special engineering equipment is equipped with two skeleton oil seals 4, which can prevent the leakage of lubricating oil or grease on the bearing 3, ensure the normal lubrication of the bearing 3, and prevent external dust, moisture and other impurities from entering the bearing 3, protecting the bearing 3 from contamination and damage; in addition, by setting the separator 5, the bearing 3 is prevented from shifting during operation, ensuring that the bearing 3 has good operating clearance and reducing the wear of the bearing 3; thus effectively improving the service life of the guide wheel.

[0043] In some embodiments, for ease of configuration, such as Figure 2 and Figure 3As shown, the inner wall of the first central hole 21 is recessed with multiple annular first grooves 22, and the multiple first grooves 22 are arranged at intervals along the axial direction; the separator 5 is an elastic retaining ring, at least a part of the elastic retaining ring is engaged in the first groove 22, and the other part of the elastic retaining ring protrudes from the inner wall of the first central hole 21 and abuts against the side wall of the outer ring of the bearing 3.

[0044] The elastic retaining ring is held in place in the first slot 22 by its own elasticity, allowing for flexible installation and removal without the need for screwing or other operations, resulting in high efficiency. The elastic retaining ring only abuts against the outer ring of the bearing 3, preventing it from affecting the operation of the bearing 3. The elastic retaining ring enables the independent separation of the bearing 3 and the skeleton oil seal 4, ensuring that the bearing 3 has good operating clearance.

[0045] In some embodiments, to achieve a stable connection between the guide wheel frame 2 and the rubber wheel 6, such as Figure 2 and Figure 3 As shown, the outer peripheral wall of the guide wheel frame 2 is recessed with multiple second slots 23; the inner wall of the second central hole 61 of the rubber wheel 6 is provided with a retaining strip 62 for engaging the second slots 23. The rubber wheel 6 is elastically clamped to the outer periphery of the guide wheel frame 2, and the limiting cooperation between the second slots 23 and the retaining strip 62 ensures that the rubber wheel 6 and the guide wheel frame 2 are relatively fixed, thus providing a stable guiding effect for the rope.

[0046] In some embodiments, to ensure that the rope can be stably guided on the rubber wheel 6, such as Figure 1 As shown, the outer peripheral wall of the rubber wheel 6 is recessed with a rope groove 63 for the rope to be inserted, and the rope groove 63 has multiple protrusions 64. The rope groove 63 can limit the rope's position, preventing it from shifting or detaching from the rubber wheel 6, while the multiple protrusions 64 increase the friction between the rope groove 63 and the rope, preventing slippage between the rope and the rubber wheel 6. The rubber wheel 6 is made of natural rubber, which has excellent wear resistance, elasticity, tensile strength, and elongation. The rubber wheel 6 is injection molded, resulting in high production efficiency, low cost, and high precision.

[0047] In the above solution, the guide wheel frame 2 of this embodiment is made of aluminum, which is lightweight and structurally stable, making it easy to reduce the overall weight of the guide wheel; the guide wheel frame 2 is integrally cast, which eliminates the need for repeated processing during production, thereby reducing waste, processing time and production costs.

[0048] In some embodiments, such as Figure 3 As shown, there are two bearings 3, both of which are deep groove ball bearings 3. The two deep groove ball bearings 3 provide rotational support for the guide wheel frame 2, ensuring that the guide wheel frame 2 can rotate stably. The dual bearing design can share the radial load, improving the stability and reliability of the rotational action.

[0049] In some embodiments, such as Figure 2-4 As shown, the support assembly 1 includes a first sealing member 11 and a second sealing member 12; the first sealing member 11 includes an end cap 111, the first end of which is integrally connected to a first oil seal section 112, and the first end of the first oil seal section 112 is integrally connected to the support shaft section 113, and the first sealing member 11 has a first mounting hole 115 arranged axially; the second sealing member 12 includes a pressure cap 121, the first end of which is integrally connected to a second oil seal section 122, and the second sealing member 12 has a second mounting hole 123 arranged axially; wherein, the end of the second oil seal section 122 abuts against the end of the support shaft section 113, the first mounting hole 115 and the second mounting hole 123 are coaxially corresponding, and two skeleton oil seals 4 are respectively installed on the first oil seal section 112 and the second oil seal section 122.

[0050] A shoulder is formed between the support shaft section 113 and the first oil seal section 112, and a shoulder is formed between the first oil seal section 112 and the end cover 111. The diameter of the second oil seal section 122 is larger than the diameter of the support shaft section 113. Figure 3 As shown, two bearings 3 are disposed between the first oil seal section 112 and the second oil seal section 122. The diameter of the gland 121 and the end cap 111 is larger than the diameter of the first central hole 21, so that the gland 121 and the end cap 111 can cover both ends of the first central hole 21 and provide protection.

[0051] Specifically, when installing the guide wheels of this special engineering equipment, with Figure 3 From the perspective of the screw (not shown), the screw passes through the second mounting hole 123 and the first mounting hole 115 from left to right and is then connected to a mounting base (not shown). In other words, the screw presses the second oil seal section 122 of the second sealing member 12 onto the support shaft section 113 of the first sealing member 11, and at the same time presses the first sealing member 11 onto the mounting base, thereby fixing the position of the support assembly 1.

[0052] When bearing 3 needs to be replaced, the screws can be unscrewed, the second end cap 12 can be disassembled, and the skeleton oil seal 4, the separator 5 and bearing 3 can be removed and replaced. The structure is easy to disassemble and convenient for maintenance.

[0053] Preferably, if Figure 4As shown, the second end of the end cap 111 of the first sealing member 11 is integrally connected to a locking post 114, the cross-section of which is non-circular. In this embodiment, the cross-section of the locking post 114 is square; in other embodiments, it can be other shapes, as long as it is not circular. Correspondingly, the mounting base (not shown) is provided with a hole for the locking post 114 to be inserted. The shape of the hole matches the outer contour of the locking post 114. By limiting the connection between the hole on the mounting base and the locking post 114, the support assembly 1 can be fixed and not rotated, ensuring that the guide wheel of the special engineering equipment can work stably.

[0054] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
