Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rail cutting machines, and specifically relates to a dual-lithium battery rail cutting machine with enhanced balance and heat dissipation. Background Technology
[0002] While some existing rail cutting machines use dual lithium battery packs for power, these packs are typically mounted above the cutting motor and symmetrically distributed around its center. This results in a rearward-positioned center of gravity, closer to the switch handle. For example, a 36V dual lithium battery rail cutting machine (patent application number CN2025213417609)... Figure 1 As shown, the dual lithium battery packs are symmetrically distributed on both sides of the center of the cutting motor, resulting in the center of gravity of the existing cutting machine being set rearward. This rearward center of gravity layout causes poor overall balance when the cutting machine cuts steel rails, resulting in unstable cutting; at the same time, the cutting machine also lacks heat dissipation measures for the lithium battery packs. Utility Model Content
[0003] The purpose of this invention is to provide a dual-lithium battery rail cutting machine with enhanced balance and heat dissipation. This invention solves the problems of poor overall balance and lack of heat dissipation when the cutting machine is cutting rails.
[0004] To address the aforementioned technical problems, this utility model provides a dual-lithium battery rail cutting machine with enhanced balance and heat dissipation, comprising: a cutting motor, a transmission disc, and a cutting blade disc, wherein the cutting motor drives the cutting blade disc to perform a rotary cutting action via the transmission disc, and further comprising:
[0005] A heat sink, securely mounted above the cutting motor, is used to dissipate heat from the lithium battery pack.
[0006] Two lithium battery packs are detachably mounted on the heat sink via locking tongue connectors, and both lithium battery packs are located on the right side of the center of the cutting motor, thereby shortening the distance between the lithium battery packs and the cutting disc.
[0007] Preferably, the heat sink includes: a heat sink base, a heat sink fan, and heat dissipation holes; the heat sink base is locked to the connecting plate of the cutting motor by screws, the heat sink fan is embedded in two slots of the heat sink base respectively, and a plurality of heat dissipation holes are opened at the bottom of the slots of the heat sink base.
[0008] Preferably, the bottom of the lithium battery pack casing also includes several oblique holes.
[0009] Preferably, the latching tongue connector further includes several connecting holes, which are arranged one-to-one with the several oblique holes. The oblique holes and the connecting holes are connected to dissipate the heat inside the lithium battery pack through the cooling fan.
[0010] Preferably, the two lithium battery packs are centrally symmetrically distributed.
[0011] Preferably, it also includes a switch handle, a top lifting handle, and a bottom lifting handle; the switch handle is locked to the cutting motor on the side away from the transmission plate by screws, the top lifting handle is locked to the upper right side of the cutting motor by screws and is located between the two lithium battery packs, one end of the bottom lifting handle is locked to the switch handle, and the other end is locked to the bottom of the cutting motor.
[0012] Preferably, it also includes a fixed sleeve and a rail fixing bracket. The fixed sleeve is detachably locked onto the transmission disc. One end of the rail fixing bracket is inserted into the fixed sleeve through a fixed insert shaft, and the other end is fixed to the rail through a locking claw.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] This invention moves the dual lithium battery packs forward, placing them both on the right side of the cutting motor center, closer to the cutting disc. This shifts the cutting machine's center of gravity forward, improving overall balance when cutting steel rails and achieving smoother cutting. Additionally, the design of a cooling fan structure enhances heat dissipation for the 36V lithium battery packs. Attached Figure Description

Detailed Implementation
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0023] like Figures 1-6 As shown, this utility model embodiment specifically provides a dual-lithium battery rail cutting machine with enhanced balance and heat dissipation, including: a cutting motor 1, a transmission disk 2, and a cutting blade disk 3. The cutting motor 1 drives the cutting blade disk 3 to perform a rotary cutting action through the transmission disk 2. It also includes:
[0024] Heat sink 4 is locked and installed above the cutting motor 1 to dissipate heat from the lithium battery pack 5;
[0025] Two lithium battery packs 5 are detachably mounted on the radiator 4 via locking tongue connectors 6. Both lithium battery packs 5 are positioned to the right of the center of the cutting motor 1, thus shortening the distance between the lithium battery packs 5 and the cutting disc 3. By moving the dual lithium battery packs 5 forward as a whole, i.e., installing them to the right of the center of the cutting motor 1, closer to the cutting disc 3, the structural center of gravity of the cutting machine is shifted forward, thereby improving the overall balance of the cutting machine when cutting the steel rail and achieving stable cutting.
[0026] The heat sink 4 includes a heat sink base 41, a heat sink fan 42, and heat dissipation holes 43. The heat sink base 41 is fastened to the connecting plate of the cutting motor 1 by screws. The heat sink fan 42 is embedded in each of the two slots of the heat sink base 41, and several heat dissipation holes 43 are opened at the bottom of the slots of the heat sink base 41. At the same time, the heat dissipation effect of the 36V lithium battery pack 5 is improved by designing the structure of the heat sink fan 42.
[0027] The bottom of the lithium battery pack 5 housing also includes several oblique holes 51; the latching seat 6 also includes several connecting holes 61, which are arranged one-to-one with the oblique holes 51, and the oblique holes 51 and the connecting holes 61 are connected to each other so that the heat inside the lithium battery pack 5 can be dissipated by the cooling fan 42.
[0028] The two lithium battery packs are centrally symmetrically distributed.
[0029] It also includes a switch handle 7, a top lifting handle 8, and a bottom lifting handle 9; the switch handle 7 is locked to the cutting motor 1 on the side away from the transmission disk 2 by screws, the top lifting handle 8 is locked to the upper right side of the cutting motor 1 by screws and is located between the two lithium battery packs 5, one end of the bottom lifting handle 9 is locked to the switch handle 7, and the other end is locked to the bottom of the cutting motor 1.
[0030] It also includes a fixed sleeve 10 and a rail fixing swing bracket 11. The fixed sleeve 10 is detachably locked onto the transmission disc 2. One end of the rail fixing swing bracket 11 is inserted into the fixed sleeve 10 through a fixed insert shaft, and the other end is fixed onto the rail through a locking claw, so as to realize swing sawing of the rail.
[0031] The improvements and innovations of this utility model embodiment lie in the forward shift of the center of gravity of the cutting machine and the addition of a heat dissipation structure for the lithium battery pack 5. The other structures of the lithium battery cutting machine, such as the transmission disc 2, the cutting disc 3, the fixed sleeve 10, and the rail fixed swing frame 11, as well as their connection relationships, are all structures well known to the prior art or those skilled in the art, and therefore will not be described in detail here.
[0032] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
