Abstract
Description
Technical Field
[0001] The utility model relates to an eddy current retarder bracket assembly and belongs to the technical field of new energy mining vehicles. Background Art
[0002] The eddy current retarder uses the principle of electromagnetic induction to convert the kinetic energy of the vehicle into heat energy when the vehicle needs to slow down, so that the vehicle can achieve the purpose of deceleration and play an auxiliary braking role. The retarder consists of a rotor and a stator. The rotor is connected to the vehicle drive shaft, and the stator is indirectly connected to the frame through a bracket. When the vehicle needs to slow down, the retarder stator is connected to the power supply, the stator coil generates a magnetic field, and the high-speed rotating rotor cuts the magnetic lines of force, forming eddy currents inside the rotor, generating a reverse braking torque, and slowing down the vehicle. At the same time, when the rotor rotates, the heat generated by the eddy current is dissipated through the fan blades on the rotor. When the eddy current retarder generates heat during continuous operation, its internal temperature will be too high, resulting in a poor auxiliary braking effect, leading to a safety hazard in the braking of the entire vehicle. Therefore, the heat dissipation performance of the eddy current retarder is very important.
[0003] As the main component connecting the retarder and the frame, the shape and structural characteristics of the eddy current retarder bracket directly affect the stability and reliability of the retarder during operation. The existing patent CN217623152U proposes a new type of eddy current retarder bracket for mine cars. The patent mainly focuses on the design of shock-absorbing gaskets to reduce the vibration generated by the retarder during operation and improve the life of the retarder bracket. Although the patent effectively avoids the high vibration working conditions at the mine car operation site, it does not take into account the adverse effects of sand and mud at the bottom of the mine car on the eddy current retarder: since the bottom of the eddy current retarder is unprotected and the mine car operation site is often accompanied by splashing sand and mud, the splashing sand and mud can easily hit the eddy current retarder, and even worse, the splash enters the inside of the eddy current retarder and accumulates adhesion, which has an adverse effect on the heat dissipation performance and safety of use of the eddy current retarder. Summary of the invention
[0004] In view of the shortcomings of the prior art, the utility model proposes a novel eddy current retarder bracket assembly, which can prevent the sand and gravel splashing from the bottom of the mine car from damaging the eddy current retarder, and at the same time prevent mud splashing from covering the surface of the eddy current retarder or entering the inside of the eddy current retarder, thereby ensuring the heat dissipation performance and safety performance of the eddy current retarder.

[0034] Further solutions, such as Figure 1 , Figure 3 , Figure 5 As shown, the baffle 106 has a filling window at the grease filling position h at the bottom of the eddy current retarder 108, and the filling window is sealed by the cover plate 105 to protect the grease filling position h. By opening the grease filling window on the baffle 106, when filling grease into the eddy current retarder 108, it is not necessary to disassemble the entire baffle 106, but only the cover plate 105 needs to be disassembled, which facilitates the maintenance of the eddy current retarder 108.
[0035] The preferred solution is Figure 3 As shown, a plurality of through holes Ⅰa are provided on the baffle 106 around the filling window, and a through hole Ⅱb corresponding to the through holes Ⅰa is provided on the cover plate 105; a nut coaxially arranged with the through hole Ⅰa is welded to each of the plurality of through holes Ⅰa on the inner side surface of the baffle 106, and a bolt passes through the through hole Ⅱb and is screwed into the nut to fix the cover plate 105 on the baffle 106.
[0036] like Figure 1 , Figure 4 As shown, the baffle 106 is a bent plate that is bent multiple times to match the outer contour of the eddy current retarder; the baffle 106 is detachably mounted on the left bracket 107 and the right bracket 102 .
[0037] Further solutions, such as Figure 1 , Figure 4 As shown, the two ends of the baffle 106 are fixed to the left bracket 107 and the right bracket 102 by sharing part or all of the fastening components on the left bracket 107 and the right bracket 102 for fixing the left and right brackets to the eddy current retarder 108 .
[0038] The preferred solution is Figure 1 , Figure 3 , Figure 5As shown, a plurality of threaded holes f distributed up and down are symmetrically provided on the left and right side surfaces of the eddy current retarder 108, and through holes IIIc corresponding to the plurality of threaded holes f are provided on the left bracket 107 and the right bracket 102; the fastening components are bolts 104, and the left bracket 107 and the right bracket 102 are fixed to the eddy current retarder 108 by the plurality of bolts 104; at least one through hole IVd corresponding to the through hole IIIc is provided at each end of the baffle 106, and the bolts 104 are penetrated through the through holes IVd and IIIc and then tightened in the threaded holes f of the eddy current retarder 108, so as to fix the baffle 106 to the left bracket 107 and the right bracket 102 together.
[0039] The specific embodiment is as follows: two through holes IIIc are respectively provided on the vertical plates 302 of the left bracket 107 and the right bracket 102, and two through holes IVd corresponding to the two through holes IIIc at the bottom are respectively provided at both ends of the baffle 106. With such an arrangement, when the baffle 106 is connected with the left bracket 107 and the right bracket 102, two bolts 104 of the left and right brackets and the eddy current retarder are used, thereby reducing the use of bolted connectors.
[0040] Further solutions, such as Figure 4 As shown, there is a certain gap g between the baffle 106 installed on the left bracket 107 and the right bracket 102 and the eddy current retarder 108, which will not affect the circulation of air at the bottom of the eddy current retarder 108, so the baffle 106 will not have an adverse effect on the heat dissipation performance of the eddy current retarder 108.
[0041] like Figure 1 , Figure 2 As shown, the left bracket 107 and the right bracket 102 have the same structure, both of which are right-angle plate structures; the vertical plates 302 of the left bracket 107 and the right bracket 102 are assembled together with the eddy current retarder 108, and the horizontal plates 301 of the left bracket 107 and the right bracket 102 are assembled together with the frame through at least one connecting piece with a shock-absorbing function to reduce the impact of vibration shock on the eddy current retarder 108.
[0042] Further solutions, such as Figure 2 As shown, a plurality of rib plates 303 are welded between the vertical plate 302 and the horizontal plate 301 in the left bracket 107 and the right bracket 102 at intervals, so as to increase the strength of the left bracket 107 and the right bracket 102 .
[0043] like Figure 1As shown, the connecting parts include two rubber shock-absorbing pad assemblies 101, bolts and locking nuts 103; the two rubber shock-absorbing pad assemblies 101 are respectively located on the upper and lower surfaces of the horizontal plate 301, and the central through holes of the two rubber shock-absorbing pad assemblies 101 are coaxially arranged with the through hole Ⅴe on the horizontal plate 301; the bolts are fastened by the locking nuts 103 to fix the frame, the two rubber shock-absorbing pads 101 and the horizontal plate 301 together.
[0044] Further solutions, such as Figure 1 As shown, the locking nut 103 is composed of two common nuts stacked together; or, the locking nut 103 is composed of an ordinary nut and a positioning pin inserted on a bolt located below the nut; the locking nut 103 can solve the problem of loosening of the fixing nut caused by frame vibration, thereby avoiding accidents.
[0045] It should be noted that if further protection for the bottom of the retarder is required, the width of the bottom baffle can be increased or the baffle can be bent in the front-to-back direction. Although this method increases protection against external mud and sand splashing, it also has a certain impact on the heat dissipation effect of the eddy current retarder.
[0046] The utility model also provides a new energy mining vehicle, comprising a vehicle frame and an eddy current retarder, wherein the eddy current retarder is connected to the vehicle frame through the above-mentioned eddy current retarder bracket assembly.
[0047] In summary, a baffle 106 of the shape shown in the figure is added below the eddy current retarder 108, and the baffle 106 is fixed together with the brackets 102 and 107 on both sides of the eddy current retarder by bolt connection, and together constitutes the eddy current retarder bracket assembly. The width of the baffle 106 is the same as the thickness of the eddy current retarder, and the shape of the baffle 106 is consistent with the bottom contour of the eddy current retarder, which can effectively block the impact of sand and mud at the bottom of the mine car on the eddy current retarder, avoid the damage of sand and mud to the internal structure of the eddy current retarder, and ensure the heat dissipation performance and safety performance of the eddy current retarder itself.
[0048] A grease filling window is provided on the baffle 106, and the cover plate 105 and the baffle 106 are fixed by bolt connection. Therefore, when regularly filling grease, it is not necessary to disassemble the entire baffle 106, but only the cover plate 105 needs to be removed, and the operation is quick and convenient.
