Description

Technical Field

[0001] This utility model belongs to the technical field of rail cutting machines, and specifically relates to a 36V dual-lithium battery rail cutting machine. Background Technology

[0002] While some existing rail cutting machines use lithium battery packs for power, most are modularly powered by a single 72V lithium battery pack. For example, a 72V lithium battery integrated rail cutting machine (publication number CN214557827U) includes an external rotor brushless motor, cutting components, and a power battery pack. This 72V lithium battery integrated rail cutting machine replaces the existing plug-in motor with a power battery pack and an external rotor brushless motor, achieving integrated self-powered operation.

[0003] However, the existing 72V single lithium battery pack power supply method is generally composed of several individual cells connected in series, such as 20 to 24, to achieve an output voltage of 72V. However, if one of the cell modules is damaged, in order to ensure the reliability and safety of the power supply, the entire 72V lithium battery pack needs to be replaced, which increases the maintenance cost. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] like Figures 1-6 As shown, this utility model embodiment specifically provides a 36V dual-lithium battery rail cutting machine, including:

[0030] Two 36V lithium battery packs 1 are provided to provide power to the motor 2; the two 36V lithium battery packs 1 are connected in series and can be detachably locked onto the mounting base 3 on the top of the motor 2.

[0031] The connecting plate 4 is mounted on one end to the motor 2 and on the other end to a rotatable cutter head 5. The motor 2 and the cutter head 5 are connected by a transmission mechanism 6. The connecting plate 4 includes a main connecting plate 41 and a secondary connecting plate 42. The main connecting plate 41 and the secondary connecting plate 42 are detachably locked together. By adjusting the distance between the main connecting plate 41 and the secondary connecting plate 42, the length between the driving pulley and the driven pulley is made less than the length of the transmission belt. This makes it easier for assembly or maintenance personnel to install the transmission belt when it is spliced, saving time and effort.

[0032] The fixed sleeve 7 has a through groove 43 and a waist-shaped slot 44 on the main connecting plate 41. The fixed sleeve 7 is movably inserted into the through groove 43, and the fixed sleeve 7 is locked in place by the waist-shaped slot 44 with locking bolts. The fixed sleeve 7 includes a plug-in sleeve 71, a fixed cylinder 72, a locking block 73, and a stop screw 74. The plug-in sleeve 71 is inserted into the fixed cylinder 72. A locking block 73 is integrally formed on one side of the outer wall of the fixed cylinder 72. Several stop screws 74 are threaded into the locking block 73. By tightening the stop screws 74, their ends are pressed against the plug-in sleeve 71 to achieve the stop and limit of the plug-in sleeve 71. The plug shaft 81 is inserted into the fixed sleeve 7, allowing the operator to swing the cutting machine to cut the rail when performing cutting operations. Furthermore, the aforementioned fixed sleeve 7 is detachably locked onto the main connecting plate 41. When swing cutting is required, it is installed and locked. When swing cutting is not required, the fixed sleeve 7 can be removed, thereby enabling flexible matching and switching between the fixed sleeve 7 and the fixed swing frame 8.

[0033] The main connecting plate 41 also includes a second waist-shaped slot 45. The first waist-shaped slot 44 and the second waist-shaped slot 45 are linearly spaced at one end of the main connecting plate 41, and the second waist-shaped slot 45 is locked and fixed to the secondary connecting plate 42 by locking bolts; so as to achieve the purpose of quickly adjusting and locking the distance between the secondary connecting plate 42 and the main connecting plate 41.

[0034] The through slot 43 is formed between the first waist-shaped slot 44 and the second waist-shaped slot 45.

[0035] It also includes a fixed swing frame 8, one end of which is fixed and locked to the rail, and the other end is equipped with a plug shaft 81. The plug shaft 81 is inserted into the fixed sleeve 7 to realize the swing cutting of the rail by the cutting machine.

[0036] It also includes a positioning mechanism 9, which includes: a fixing block 91, a positioning rod 92, a spring 93, a limiting block 94, and an abutment block 95. The fixing block 91 is installed on the secondary connecting plate 42. The positioning rod 92 is slidably inserted into the fixing block 91. The spring 93 is sleeved on the positioning rod 92. One end of the spring 93 abuts against the limiting block 94, and the other end abuts against the U-shaped groove wall of the fixing block 91. The limiting block 94 is fixedly sleeved on the positioning rod 92. The abutment block 95 is set at one end of the main connecting plate 41 and is used to abut against the end of the positioning rod 92 for positioning. With the aforementioned positioning mechanism 9, when the transmission belt is installed, the positioning rod 92 on the secondary connecting plate 42 moves closer to the abutment block 95, and its spring 93 is compressed. At this time, the length of the transmission belt is greater than the distance between the driven pulley and the driving pulley, making it easier to install the transmission belt. After installation, the tension of the transmission belt needs to be adjusted. By moving the secondary connecting plate 42 away from the main connecting plate 41, the compressed spring 93 gradually returns to its free state, and the end of the positioning rod 92 still abuts against the abutment block 95, but the spring 93 is not compressed. At this time, the main connecting plate 41 and the secondary connecting plate 42 can be tightened and locked with locking bolts to achieve the purpose of positioning indication of the locking position of the main connecting plate 41 and the secondary connecting plate 42. Furthermore, after locking the main connecting plate 41 and the secondary connecting plate 42, the aforementioned fixing sleeve 7 can be locked and fixed to the main connecting plate 41, and the outer wall of the fixing sleeve 7 abuts and clamps against the end face of the secondary connecting plate 42, further enhancing the overall stability of the connecting plate 4 structure.

[0037] It also includes a main protective shell 46 and a secondary protective shell 47, which are detachably locked to the main connecting plate 41 and the secondary connecting plate 42 by locking screws, so as to cover and protect the transmission mechanism 6 and avoid external interference.

[0038] The transmission mechanism 6 includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is connected to the output end of the motor 2, the driven pulley is connected to the shaft end of the cutter head 5, and the driving pulley and the driven pulley are connected by the transmission belt.

[0039] The end face of the secondary connecting plate 42 is an arc-shaped surface, which is used to fit and abut against the outer wall of the fixed sleeve 7 for better limiting, clamping and fixing.

[0040] It also includes a power adapter socket 10, which is installed on one side of the motor 2; by connecting the adapter plug of the external power cord to the power adapter socket 10, the motor 2 can be provided with working power. This setting can reduce the weight of the operator's hands when removing the 72V lithium battery pack, and can also be used as a backup to keep the cutting machine running.

[0041] It also includes a main handle 11 and a secondary handle 12. The upper end of the side wall of the main handle 11 is connected to the mounting base 3, and the lower end is connected to the motor 2. The lower end of the secondary handle 12 is connected to the mounting base 3 on the side away from the main handle 11, and the secondary handle 12 is designed with a bent U-shaped rod structure. By holding the main handle 11 and the secondary handle 12, it is easy to lift the cutting machine for cutting operations, and the bent U-shaped rod structure of the secondary handle 12 makes it more labor-saving.

[0042] 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.
