Description

Technical Field

[0001] This utility model relates to the field of transport locomotive technology, and in particular to a hybrid drive locomotive. Background Technology

[0002] In coal mines, the transportation of personnel, materials, equipment, gangue, and other items besides coal transportation is collectively referred to as auxiliary transportation. Auxiliary transportation can be divided into two main types: rail transportation and trackless transportation. Trackless transportation typically uses rubber-tired or tracked vehicles as its running gear; however, its adaptability is clearly insufficient when facing roadways with steep inclines, making it difficult to meet the transportation needs under complex working conditions.

[0003] Existing wheel-driven locomotives in rail transport mainly rely on adhesive drive wheels for power, enabling efficient transport at relatively high speeds in flat roadways. However, this type of locomotive has extremely limited climbing ability and is only suitable for roadways with gentle slopes and minimal undulations. Once the terrain of the roadway changes significantly, it cannot operate normally, greatly limiting its application scenarios.

[0004] While rack-and-pinion locomotives effectively solve the transportation challenges of steep gradients, heavy loads, and undulating roadways, their reliance on dedicated rack tracks results in relatively slow operating speeds and high track laying costs. Especially in long-distance horizontal roadway transportation scenarios, users not only face significant upfront investment but also encounter bottlenecks in improving transportation efficiency. Neither rack-driven nor wheel-driven locomotives can fully meet the diverse transportation needs of underground coal mines, limiting the application range of rack-and-pinion or adhesive-wheel-driven locomotives and hindering the improvement of their overall performance.

[0053] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0054] Example 1

[0055] This embodiment relates to a hybrid drive locomotive, which aims to improve the quality of transport locomotive use by optimizing its application range.

[0056] As shown in the figure, the hybrid drive transport locomotive in this embodiment includes a chassis 1, a power unit 2, a wheel drive mechanism 3, and a gear drive mechanism 4. The chassis 1 carries the power unit 2, the wheel drive mechanism 3, and the gear drive mechanism 4. When the hybrid drive locomotive travels on the track, the power unit 2 supplies power to the wheel drive mechanism 3, causing the wheel drive mechanism 3 to drive the hybrid drive locomotive on the track. When the hybrid drive locomotive travels on the geared track, the power unit 2 supplies power to the gear drive mechanism 4, causing the gear drive mechanism 4 to drive the hybrid drive locomotive on the geared track.

[0057] As configured above, the hybrid drive locomotive in this embodiment, by arranging a power unit 2 on the chassis 1, can drive the wheel drive mechanism 3 and the gear drive mechanism 4 to operate. The power unit 2 drives the wheel drive mechanism 3 to operate, which in turn drives the hybrid drive locomotive to run on the track. The power unit 2 drives the gear drive mechanism 4 to operate, which in turn drives the hybrid drive locomotive to run on the rack rail. The arrangement of the wheel drive mechanism 3 and the gear drive mechanism 4 allows the hybrid drive locomotive to run on both the track and the rack rail, making it easy to adapt to different track conditions. Moreover, operators can select the corresponding wheel drive mechanism 3 and gear drive mechanism 4 according to different track conditions, which is beneficial for the rapid operation of the hybrid drive locomotive in flat tunnels and its operation when climbing slopes, thus improving the scope of use of the hybrid drive locomotive and enhancing the quality of transport locomotive use.

[0058] It should be noted that, in this embodiment, the track on which the wheel drive mechanism 3 travels refers to a track without a toothed rail, while a toothed rail refers to a track containing a toothed rail.

[0059] Specifically, in this embodiment, as an exemplary structure, combined with Figures 1 to 7 The hybrid drive locomotive shown in this embodiment further includes a main driver's cab 5, an auxiliary vehicle 6, and a co-driver's cab 7. The chassis 1 of the hybrid drive locomotive in this embodiment includes a first frame 101, a second frame 102, a third frame 103, and a fourth frame 104 connected in sequence. The main driver's cab 5 is located on the first frame 101, the auxiliary vehicle 6 is located on the second frame 102, the power unit 2 and the wheel drive mechanism 3 are located on the third frame 103, the co-driver's cab 7 is located on the fourth frame 104, and the gear drive mechanism 4 is located on the first frame 101 and the fourth frame 104. This makes the chassis 1, including the first frame 101, the second frame 102, the third frame 103, and the fourth frame 104, convenient for the arrangement of the main driver's cab 5, the auxiliary vehicle 6, the co-driver's cab 7, the power unit 2, the wheel drive mechanism 3, and the gear drive mechanism 4, and the structure is simple and easy to design and implement.

[0060] In this embodiment, the main driver's cab 5, the auxiliary vehicle 6, and the co-driver's cab 7 are all set up with the structure that is used in the prior art. The main driver's cab 5 is used by the operator to control the vehicle to move forward, the auxiliary vehicle 6 is used to house the vehicle's control box, electrical room and other auxiliary mechanisms, and the co-driver's cab 7 is used by the operator to control the vehicle to move backward.

[0061] Furthermore, the auxiliary mechanisms involved in the auxiliary vehicle 6 in this embodiment can also be arranged on the same chassis as the main driver's cab 5 and the co-driver's cab 7, which can make it easier to eliminate the need for the auxiliary vehicle 6 and make better use of the overall vehicle space.

[0062] In this embodiment, in order to better arrange the wheel drive mechanism 3, as an exemplary structure, combined with Figures 1 to 7As shown, the wheel drive mechanism 3 in this embodiment includes a first wheel drive unit 301 and a second wheel drive unit 302 sequentially arranged below the third frame 103 along the front-rear direction of the locomotive.

The second wheel drive unit 302 is driven by the power device 2 to run along the track and achieves rotation with first, second, and third degrees of freedom. It is worth mentioning that the first degree of freedom is rotational motion along the vehicle height direction, the second degree of freedom is rotational motion along the vehicle width direction, and the third degree of freedom is swinging motion along the vehicle width direction. By sequentially arranging the first wheel drive unit 301 and the second wheel drive unit 302 below the third frame 103, vehicle steering is facilitated, and multiple degrees of freedom are provided, making design and implementation easier.

The first braking part 3014 is located on the first connecting part 3012 and can brake the first drive wheel set 3013. The first steering unit 3011 may be a slewing bearing, for example, and the first drive wheel set 3013 may be driven by a hydraulic motor, for example.

[0064] The first steering part 3011 facilitates rotation with a first degree of freedom at the front of the third frame 103.

The first main shaft 30122 facilitates the second degree of freedom of rotation at the front of the third frame 103. The first wheel frame 30123 facilitates the arrangement of the first drive wheel set 3013, the first rail-mounted wheel set 3015, and the first brake part 3014. The structure is simple and easy to design and implement.

On 22, to achieve rotation of the third degree of freedom, the second drive wheel set 3024 is respectively provided on both sides of the second connecting part 3022, so as to drive the hybrid drive locomotive to run along the track under the drive of the power unit 2. The second rail clamping wheel set 3026 is respectively provided below the second drive wheel set 3024 and can roll on the side of the track to constrain the second wheel drive unit 302 on the track. The second braking part 3025 is provided on the second connecting part 3022 and can brake the second drive wheel set 3024.

The second drive wheel set 3024, the second brake part 3025, and the second rail wheel set 3026 are all mounted on the second wheel frame 30223. The second connecting frame 30221 facilitates the connection between the second connecting part 3022 and the second steering part 3021. The second main shaft 30222 facilitates the second degree of freedom of rotation at the rear of the third frame 103. The second wheel frame 30223 facilitates the arrangement of the second drive wheel set 3024, the second rail wheel set 3026, and the second brake part 3025. The structure is simple and easy to design and implement.

[0068] In the second wheel drive unit 302 of this embodiment, combined with Figure 6 As shown, the swing part 3023 includes a rotating shaft 30231 passing through the second main shaft 30222, an annular limiting groove 30232 provided on the second main shaft 30222, and an annular limiting block 30233 provided on the second connecting frame 30221. The outer side wall of the annular limiting block 30233 slides against the outer groove wall of the annular limiting groove 30232, and there is a gap between the inner side wall of the annular limiting block 30233 and the inner groove wall of the annular limiting groove 30232. The rotation direction of the rotating shaft 30231 is perpendicular to the rotation direction of the second main shaft 30222. The second main shaft 30222 can rotate around the rotating shaft 30231, and when the second main shaft 30222 rotates, the inner side wall of the annular limiting block 30233 slides along the outer groove wall of the annular limiting groove 30232. The second main shaft 30222 can rotate around the rotating shaft 30231 by means of the rotating shaft 30231 set on the second main shaft 30222, so as to realize the rotation of the third degree of freedom. Furthermore, the setting of the annular limiting block 30233 and the annular limiting groove 30232 facilitates the constraint of the rotation range of the third degree of freedom. The structure is compact and easy to design and implement.

[0069] In addition, the gear drive mechanism 4 in this embodiment can also be configured according to the vehicle's carrying requirements.

When the vehicle requires three-wheel drive, one gear drive mechanism 4 can be arranged on each of the first frame 101, the second frame 102, and the fourth frame 104, or... Two gear drive mechanisms 4 are arranged on the first frame 101 and one gear drive mechanism 4 is arranged on the fourth frame 104. Alternatively, one gear drive mechanism 4 can be arranged on the first frame 101 and two gear drive mechanisms 4 can be arranged on the fourth frame 104. When the vehicle requires two-wheel drive, one gear drive mechanism 4 can be arranged on the first frame 101 and one on the fourth frame 104. The arrangement of the gear drive mechanism 4 can be set according to the actual carrying requirements. The connection method between the gear drive mechanism 4 and the chassis 1 can be, for example, the arrangement method of arranging the gear drive mechanism 4 on the chassis 1 in the prior art.

[0070] Specifically, in combination Figure 1 and Figure 2 As shown, the gear drive mechanism 4 in this embodiment includes a bracket, a gear drive unit 401, a gear drive disk 402, a gear drive brake unit 403, a traveling wheel set 404, and a third rail-clamping wheel set 405. The gear drive unit 401 is mounted on the bracket to drive the gear drive disk 402 to run along the gear track. The gear drive brake unit 403 is mounted on the bracket to prevent the gear drive disk 402 from running along the gear track. The traveling wheel set 404 is mounted on the bracket and rolls along the top of the track when the hybrid drive mechanism is running. The third rail-clamping wheel set 405 can roll on the side of the track to constrain the gear drive mechanism 4 to the track. The bracket facilitates the installation of the gear drive unit 401, gear drive disc 402, traveling wheel set 404, and third rail-clamping wheel set 405. The gear drive unit 401 facilitates driving the gear drive disc 402 along the gear rail. The traveling wheel set 404 facilitates the locomotive's movement along the track in gear drive mode. The third rail-clamping wheel set 405 helps to restrain the locomotive on the track, preventing derailment and facilitating design implementation.

[0071] More specifically, the gear drive unit 401 in this embodiment includes a drive unit and a transmission unit that is driveably connected to the drive unit. The drive unit and the transmission unit are respectively located on both sides of the gear drive disk 402, and the transmission unit is driveably connected to the gear drive disk 402.
