Technical Field
[0001] This utility model relates to the field of engineering machinery technology, specifically a new type of wheel rim, wheel rim fastening fixture, and mining dump truck. Background Technology
[0002] Mining dump trucks typically have four wheels on their rear axle. In actual operation and maintenance, the wheel rim fasteners need to be tightened a second time according to technical requirements. However, ordinary wheel rim structures make it difficult to tighten the fasteners on the inner side of the axle rim, that is, the side closest to the rear axle housing, which reduces the safety and reliability of vehicle operation. Utility Model Content
[0003] The purpose of this utility model is to provide a new type of wheel rim, wheel rim fastening fixture and mining dump truck, so as to solve the problem that the fasteners of the inner side of the rear axle wheel rim of the conventional mining dump truck are inconvenient to be fastened for secondary fastening as mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel wheel rim, comprising: a wheel rim body and a spoke plate integral with the wheel rim body, wherein a plurality of connecting holes are provided on the spoke plate, and the wheel rim body is mounted on a reducer by fasteners passing through the connecting holes; the spoke plate is also provided with an inner fastening hole at the periphery of the reducer for maintenance and secondary fastening of the inner wheel rim fasteners.
[0005] Preferably, the inner fastening holes are provided in several groups on the spokes.
[0006] Preferably, the internal fastening holes are evenly spaced in an array on the spokes.
[0007] A wheel rim fastening fixture is used for the secondary fastening of the aforementioned novel wheel rim. The fastening fixture includes: a torque wrench and a sleeve installed at the end of the torque wrench. The torque wrench passes through the inner fastening hole and fastens the inner wheel rim fasteners through the sleeve.
[0008] Preferably, the sleeve and the torque wrench are universally connected.
[0009] Preferably, the end of the torque wrench away from the socket is further provided with an extension rod.
[0010] Preferably, the extension rod and the torque wrench are welded together.
[0011] A mining dump truck is equipped with the aforementioned new type of wheel rim.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model eliminates the opening and fasteners at the rim connecting plate and sets up an inner fastening hole. The fasteners on the inner rim are then fastened a second time by passing through the inner fastening hole with a fastening fixture. This method facilitates the secondary fastening operation and is simpler in rim structure than the existing technology, making installation and maintenance more convenient.
[0014] The sleeve with the inner fastening hole and universal connection can be stably secured when the fasteners on the inner rim are tightened for the second time, without changing the relative position of the fasteners on the inner rim. Attached Figure Description

[0021] 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.
[0022] Please see Figures 1-4 This utility model provides a novel wheel rim, such as Figure 1 As shown, it includes: a rim body 1 and a spoke plate 13 integral with the rim body 1. Several connecting holes 12 are opened on the spoke plate 13. The rim body 1 is installed on the reducer by fasteners 3 passing through the connecting holes 12. An inner fastening hole 11 is also opened on the spoke plate 13 at the periphery of the reducer for maintenance and secondary fastening of the inner rim fasteners 3.
[0023] As a further limitation, as shown in Figure 2, several sets of internal fastening holes 11 are provided on the spoke plate 13, and the internal fastening holes 11 are evenly distributed in an array on the spoke plate 13. Those skilled in the art can appropriately set the number and diameter of the internal fastening holes 11 according to actual needs and working conditions.
[0024] It should be noted that since the inner fastening hole 11 is not on the same axis as the fastener 3 on the inner rim after the vehicle stops moving, the diameter of the inner fastening hole 11 in this embodiment allows the fastening fixture 2 to pass through and fasten two to three fasteners 3 on the inner rim without changing the relative position of the inner rim fasteners 3. This allowance ensures that all bolts on the inner rim can be fastened.
[0025] At the same time, it was cancelled such as Figure 5 The opening at the rim connecting disc 4 and the fastener 3 shown make installation more convenient and the structure is simpler than existing technologies.
[0026] like Figure 3 As shown, a rim fastening fixture is used for secondary fastening of the aforementioned novel rim. The fastening fixture 2 includes: a torque wrench 22 and a socket 23 installed at the end of the torque wrench 22, as shown. Figure 4 As shown, during the secondary tightening, the torque wrench 22 passes through the inner tightening hole 11 and the sleeve 23 to tighten the inner rim fastener 3.
[0027] As further explanation: The socket 23 and the torque wrench 22 are universally connected, and by changing the angle of the socket 23, the fastener 3 that is not on the same axis as the inner fastening hole 11 can be stably fitted and secured.
[0028] As a further limitation, the end of the torque wrench 22 away from the socket 23 is also provided with an extension rod 21.
[0029] As further explanation: the extension rod 21 and the torque wrench 22 are welded together.
[0030] A mining dump truck is equipped with the aforementioned new type of wheel rim.
[0031] Any content not described in detail in this specification is prior art known to those skilled in the art.
[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
