Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gravity energy storage power generation, and particularly relates to a heavy object carrying vehicle for gravity energy storage. BACKGROUND

[0002] The heavy object carrying vehicle for gravity energy storage is a special vehicle specially used for transporting and placing heavy objects to realize mutual conversion between gravity potential energy and electric energy. In the gravity energy storage system, it is responsible for lifting heavy objects to a certain height to store energy, or transporting heavy objects to a designated position to release energy when power generation is needed.

[0003] At present, in the actual application of existing gravity energy storage technology, a track system with a certain slope is usually constructed by means of the height difference formed by the natural slope of the mountain. In the energy storage operation, the heavy object carrying vehicle will climb up along the track to transport the heavy object to a high place to complete energy storage; when power generation is needed, the heavy object carrying vehicle will slide down along the track to drive the generator to operate by using the gravity potential energy of the heavy object, so as to convert the gravity potential energy into electric energy and send it back to the power grid to meet the power demand.

[0004] However, since the distance between the wheels on both sides of the heavy object carrying vehicle is usually fixed and cannot be adjusted, and the mountain terrain in different regions is complex and diverse, the width of the track often differs greatly. This makes it difficult for the wheels with fixed spacing to flexibly adapt to various different specifications of the track.

[0030] When the heavy object carrying vehicle for gravity energy storage is working, the wheel set 2 is symmetrically arranged at both ends of the bottom plate 1.

[0031] By setting the adjustable track wheel 5 structure, cooperating with the adjusting mechanism 10, the wheel spacing can be flexibly adjusted according to the actual situation of different regions with complex mountainous terrain and large differences in track width, so that the carrying vehicle can adapt to various different specifications of the track, avoiding safety accidents such as the carrying vehicle unable to run normally and derailment caused by the mismatch of track width, and improving the applicability of the carrying vehicle in different working environments.

[0032] In the field with wider track width, the wheel spacing can be adjusted to reduce the gap between the wheel and the track, enhance the stability and safety of the carrying vehicle operation, and further ensure the efficiency and reliability of the entire gravity energy storage system, reduce the potential risks and losses caused by unstable operation.

[0033] Second embodiment

[0034] On the basis of the first embodiment, the adjusting mechanism 10 is provided with four groups, and each adjusting mechanism 10 is connected with the corresponding track wheel 5 in cooperation, the adjusting mechanism 10 includes a second bracket 11, an adjusting screw 12 and a first sliding block 13, the second bracket 11 is fixedly arranged at the bottom of the bottom plate 1, the adjusting screw 12 is rotatably connected with the second bracket 11 in a horizontal state, the first sliding block 13 is provided with a screw hole threadedly matched with the adjusting screw 12, and the first sliding block 13 is fixedly connected with the wheel frame 8.

[0035] When it is necessary to adjust the spacing of the track wheels 5, the adjusting screw 12 is rotated, the first sliding block 13 is fixed with the wheel frame 8 and provided with a screw hole threadedly matched with the adjusting screw 12, the rotation of the adjusting screw 12 generates an axial thrust, which further pushes the wheel frame 8 to slide along the limiting sliding groove 9, the wheel frame 8 drives the sliding sleeve 6 to move on the guide shaft 4, and the spacing of the track wheels 5 is adjusted. Four adjusting mechanisms 10 correspond to four track wheels 5 respectively, and the position of each track wheel 5 can be independently adjusted to adapt to different track widths.

[0036] Third embodiment

[0037] On the basis of the first embodiment, the adjusting mechanism 10 is provided with four groups, and each adjusting mechanism 10 is connected with the corresponding track wheel 5 in cooperation, the adjusting mechanism 10 includes a second bracket 11, an adjusting screw 12 and a first sliding block 13, the second bracket 11 is fixedly arranged at the bottom of the bottom plate 1, the adjusting screw 12 is rotatably connected with the second bracket 11 in a horizontal state, the first sliding block 13 is provided with a screw hole threadedly matched with the adjusting screw 12, and the first sliding block 13 is fixedly connected with the wheel frame 8 along the vertical direction.

[0038] When the distance between the track wheels 5 needs to be adjusted, the adjusting screw 12 is rotated, the first slider 13 threaded with the adjusting screw 12 slides in the horizontal direction, and the second slider 15 on the first slider 13 slides along the slide rail 14 on the side of the wheel carrier 8, thereby driving the wheel carrier 8 to slide in the limiting slide groove 9, and further driving the sliding sleeve 6 and the track wheels 5 to move on the guide shaft 4, so as to realize the adjustment of the distance between the track wheels 5. In addition, if the first slider 13 is rigidly connected with the wheel carrier 8, when there is a high-low fluctuation in the track or a vertical vibration during driving of the bearing vehicle, the adjusting screw 12 may bear an additional torque, which aggravates the thread wear or even causes the thread to be stuck. The first slider 13 is slidably connected with the wheel carrier 8 in the vertical direction, so that the first slider 13 and the wheel carrier 8 move relatively in the vertical direction, thereby releasing the mechanical stress and prolonging the service life of the adjusting mechanism 10.

[0039] Fourth embodiment

[0040] On the basis of the first embodiment, the bottom of the bottom plate 1 is further provided with a driving mechanism 16 for driving the adjusting screws 12 in each group of adjusting mechanisms 10 to rotate synchronously, the driving mechanism 16 comprising a third bracket 17, a synchronous shaft 18, a driving bevel gear 19 and a driven bevel gear 20, the third bracket 17 being fixedly arranged at the bottom of the bottom plate 1, the synchronous shaft 18 being rotatably connected with the third bracket 17 in a horizontal state, the driven bevel gears 20 being provided with four and being coaxially fixedly connected with the corresponding adjusting screws 12, the driving bevel gears 19 being provided with two and being coaxially fixedly connected with the synchronous shaft 18, and each driving bevel gear 19 being engaged with two corresponding driven bevel gears 20.

[0041] When the distance between the track wheels 5 needs to be adjusted, the adjusting hand wheel 21 is rotated to drive the synchronous shaft 18 to rotate, the driving bevel gears 19 on the synchronous shaft 18 are rotated, the driving bevel gears 19 are engaged with the driven bevel gears 20 to transmit power to the adjusting screws 12, so that the adjusting screws 12 in the four groups of adjusting mechanisms 10 are synchronously rotated, and the synchronous adjustment of the distance between the four track wheels 5 is realized. In this way, the wheel distance can be quickly adjusted to a state suitable for different track widths.

[0042] Fifth embodiment

[0043] Based on the first embodiment, the bottom of the base plate 1 is further provided with a drive mechanism 16 for driving the synchronous rotation of the adjusting screws 12 in each group of adjustment mechanisms 10. The drive mechanism 16 includes a third bracket 17, a synchronizing shaft 18, a driving bevel gear 19, and a driven bevel gear 20.

[0044] When the spacing of the rail wheels 5 needs to be adjusted, the adjusting motor 22 drives the synchronizing shaft 18 to rotate. The synchronizing shaft 18 transmits power to the adjusting screws 12 of the four adjustment mechanisms 10 through the meshing of the driving bevel gear 19 and the driven bevel gear 20, causing the spacing of the four rail wheels 5 to change synchronously. The adjusting motor 22 can precisely control the output speed and direction through a control component such as a control system or a control terminal, enabling accurate and rapid adjustment of the spacing of the rail wheels 5 to accommodate different track specifications.

The guardrail includes a first guardrail and a second guardrail. There are multiple first guardrails and second guardrails. The first guardrails are arranged in a matrix on the top of the base plate 1, and each second guardrail is fixedly installed between two adjacent first guardrails.

[0047] When a vehicle is transporting heavy objects, the guardrails on top of base plate 1 act as a barrier.
