[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The following is combined with Figures 1-5 This invention describes a split-type electric drive device.

[0024] Firstly, such as Figure 1 As shown, this utility model provides a split-type electric traction device 1, including: a fixed base 11 and an assembly base 12; the fixed base 11 is configured to be fixed to an excavator, and the fixed base 11 has a first inner cavity and a cable inlet communicating with the first inner cavity; the assembly base 12 is detachably connected to the fixed base 11, and the assembly base 12 has a second inner cavity and a cable outlet communicating with the second inner cavity; the first inner cavity and the second inner cavity are connected in sequence to form a channel for an external cable 3 to pass through.

[0025] In this embodiment, the fixing seat 11 is used to fix and install on the body of the excavator, for example, it can be installed on the undercarriage assembly 2 of the excavator; the fixing seat 11 and the mounting seat 12 are connected to form a support structure. It can be understood that the first inner cavity in the fixing seat 11 and the second inner cavity in the mounting seat 12 are both through cavities, so that the two inner cavities can be connected to form a complete channel, so that the external cable 3 of the excavator can enter the channel from the cable inlet on one side of the fixing seat 11, pass through the channel and exit from the cable outlet on one side of the mounting seat 12, so as to connect with external equipment (such as external power supply, power supply vehicle, etc.). The entire split-type power supply device 1 can support and protect the external cable 3 of the excavator extending outward, and prevent the external cable 3 from falling to the ground.

[0026] Furthermore, the fixed base 11 and the mounting base 12 are detachably connected so that the mounting base 12 can be removed from the fixed base 11 when needed, and the external cable 3 can be supported and guided only by the fixed base 11, reducing the space occupied by the support structure; or, it can be understood that the same fixed base 11 can be equipped with multiple mounting bases 12 with different structural shapes, and the construction personnel can replace the mounting base 12 connected to the fixed base 11 according to the working conditions of the excavator, so as to avoid the split-type power supply device 1 from affecting the construction operation.

[0027] The present invention discloses a split-type power supply device 1, which fixes the fixed base 11 to the excavator and detachably connects the fixed base 11 and the mounting base 12 to form a complete support structure. The channel formed inside the support structure allows the external cable 3 of the excavator to pass through and connect to external equipment, and provides support and protection for the external cable 3. At the same time, the fixed base 11 and the mounting base 12 can be disassembled, allowing construction personnel to disassemble, assemble, and replace the mounting base 12 according to the on-site working conditions, avoiding the impact of the split-type power supply device 1 on the construction operation, making the construction operation smoother, and effectively solving the problem of the large space occupied by the power supply device in the prior art, which affects the machine's movement, operation, and transportation.

[0028] Alternatively, in some embodiments, such as Figure 1 and Figure 2 As shown, the split-type traction device 1 also includes a reinforcing beam 13, one end of which is connected to the side wall of the fixed base 11, and the other end is connected to the excavator.

[0029] In this embodiment, a reinforcing beam 13 is provided on the side wall of the fixed base 11. The reinforcing beam 13 extends towards the excavator to connect with the excavator and plays a supporting and reinforcing role between the fixed base 11 and the excavator.

[0030] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two reinforcing beams 13; one reinforcing beam 13 is located on the first side of the fixed seat 11; the other reinforcing beam 13 is located on the second side of the fixed seat 11; the first side and the second side of the fixed seat 11 are two sides arranged opposite to each other along the width direction of the excavator.

[0031] In this embodiment, by providing reinforcing beams 13 on opposite sides of the fixed base 11, the reinforcing beams 13 extend along the width direction of the excavator so as to connect with the excavator. The two reinforcing beams 13 can support and fix the fixed base 11 from opposite sides, making the fixed base 11 more robust and reliable.

[0032] Specifically, the two reinforcing beams 13 can extend to the left and right motor mount arc plates of the excavator, and be welded and fixed to the corresponding motor mount arc plates.

[0033] Specifically, in some embodiments, the reinforcing beam 13 includes a beam body and a beam body cover plate. The beam body includes a connected bottom plate and side plates connected to both sides of the bottom plate. The beam body cover plate is located above the beam body and is connected to the bottom plate and the side plates respectively, so as to enhance the structural strength of the reinforcing beam 13.

[0034] In some embodiments, such as Figure 3 and Figure 4As shown, the mounting base 11 includes: a first base body 111 and a first sealing plate 112; the first base body 111 is configured to be connected to the excavator and the mounting base 12 respectively; the first base body 111 has a first inner cavity, a cable inlet and a first mounting port 113 communicating with the first inner cavity, the first mounting port 113 being located on the top of the first base body 111; the first sealing plate 112 is detachably installed on the first mounting port 113 to close the first mounting port 113.

[0035] In this embodiment, the first base 111 is the main structure of the fixed base 11. The cable inlet and the first inner cavity inside the first base 111 allow the external cable 3 to pass through. Simultaneously, by providing a first mounting port 113 at the top of the first base 111, construction personnel can insert their hands or appropriate installation tools into the first inner cavity through the first mounting port 113 to adjust and fix the position of the external cable 3 within the first inner cavity. After installation, the construction personnel can install the first sealing plate 112 into the first mounting port 113 to prevent foreign objects from falling into the first inner cavity and causing wear and damage to the external cable 3. Furthermore, it is understood that if subsequent maintenance, disassembly, or adjustment of the external cable 3 within the first inner cavity is required, the first sealing plate 112 can be removed at any time for these operations.

[0036] In some embodiments, there are multiple first mounting ports 113, and the multiple first mounting ports 113 are arranged at intervals along the length direction of the first base 111; the first sealing plate 112 and the first mounting ports 113 are provided in a one-to-one correspondence.

[0037] In this embodiment, by arranging multiple first mounting ports 113 at intervals along the length of the first base 111, sufficient working space is provided while ensuring the overall strength of the first base 111, facilitating maintenance, disassembly, and other operations of the external cable 3 within the first inner cavity by construction personnel. The one-to-one correspondence between the first sealing plate 112 and the first mounting ports 113 also allows construction personnel to remove the first sealing plate 112 at the corresponding point when necessary, in order to perform operations on the external cable 3 inside the first mounting port 113 at the corresponding point.

[0038] In one specific embodiment, the first base 111 is a box-shaped structure formed by connecting an upper panel, a lower panel, two end connecting plates, and two side panels. The upper and lower panels are arranged opposite each other, as are the two side panels and the two end connecting plates. The upper panel has multiple first mounting ports 113. One end connecting plate is located at the first end of the first base 111 for connection to an excavator, and this end connecting plate has a cable inlet. The other end connecting plate is located at the second end of the first base 111 for connection to the mounting base 12 (typically using bolts). Exemplarily, the periphery of the end connecting plate connected to the mounting base 12 can be provided with multiple bolt holes for bolt connection to the connection structure on the mounting base 12. The middle of the end connecting plate can have a through hole adapted to the size of the external cable 3, allowing the external cable 3 to pass through while also providing a certain degree of restraint.

[0039] In some embodiments, such as Figure 3 and Figure 5 As shown, the mounting base 12 includes: a second base body 121 and a second sealing plate 122; the second base body 121 is connected to the fixed base 11; the second base body 121 is provided with a second inner cavity, a cable outlet and a second mounting port 123 communicating with the second inner cavity, the second mounting port 123 being located at the top of the second base body 121; the second sealing plate 122 is detachably installed on the second mounting port 123 to close the second mounting port 123.

[0040] In this embodiment, the second seat 121 is the main structure of the mounting base 12. The cable outlet and the second inner cavity within the second seat 121 allow the external cable 3 to pass through. Simultaneously, by providing a second mounting port 123 at the top of the second seat 121, construction personnel can insert their hands or appropriate installation tools into the second inner cavity through the second mounting port 123 to adjust and fix the position of the external cable 3 within the second inner cavity. After installation, the construction personnel can install the second sealing plate 122 into the second mounting port 123 to prevent foreign objects from falling into the second inner cavity and causing wear and damage to the external cable 3. Furthermore, it is understood that if subsequent maintenance, disassembly, or adjustment of the external cable 3 within the second inner cavity is required, the second sealing plate 122 can be removed at any time for these operations.

[0041] In some embodiments, such as Figure 3 and Figure 5 As shown, there are multiple second mounting ports 123, which are arranged at intervals along the length of the second base 121; the second sealing plate 122 and the second mounting ports 123 are set in a one-to-one correspondence.

[0042] In this embodiment, by arranging multiple second mounting ports 123 at intervals along the length of the second base 121, sufficient working space is provided while ensuring the overall strength of the second base 121, facilitating maintenance, disassembly, and other operations of the external cable 3 within the second inner cavity by construction personnel. The one-to-one correspondence between the second sealing plate 122 and the second mounting ports 123 also allows construction personnel to remove the second sealing plate 122 at corresponding points when necessary, enabling work on the external cable 3 inside the corresponding second mounting port 123.

[0043] Similar to the structure of the first base 111, the second base 121 is also a box-shaped structure formed by connecting an upper panel, a lower panel, two end connecting plates, and two side panels. The upper and lower panels are arranged opposite each other, the two side panels are arranged opposite each other, and the two end connecting plates are arranged opposite each other. The upper panel is provided with multiple second mounting ports 123. One end connecting plate is located at the first end of the second base 121 and is used to dock with the end connecting plate of the first base 111. It connects the first inner cavity and the second inner cavity through the through holes on the end connecting plate of the second base 121. The other end connecting plate is located at the second end of the second base 121 and is provided with a cable outlet for the external cable 3 to pass through.

[0044] Optionally, in some embodiments, a roller 124 is provided at the edge of the cable outlet, and the roller 124 is used to make rolling contact with the external cable 3. In this embodiment, by providing a roller 124 at the cable outlet, the roller 124 can make rolling contact with the external cable 3 at the outlet, thereby reducing the wear on the external cable 3 at the cable outlet.

[0045] In one specific embodiment, such as Figure 3 and Figure 5 As shown, the cable outlet is rectangular, and each side of the rectangular outlet is provided with a roller 124, with the axle of the roller 124 extending along the corresponding side.

[0046] Alternatively, an arcuate surface can be constructed at the edge of the cable outlet to reduce wear on the external cable 3 at the edge structure of the cable outlet.

[0047] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the split-type power supply device 1 also includes multiple cable brackets 14, which are arranged at intervals along the extension direction of the channel. The cable brackets 14 are used to fix and connect to the external cable 3.

[0048] In this embodiment, multiple cable brackets 14 are arranged along the extension direction of the channel to fix the external cable 3 to the cable brackets 14 and maintain the cable's posture. It is understood that some of the cable brackets 14 can be located in the first inner cavity, and other cable brackets 14 can be located in the second inner cavity.

[0049] Alternatively, the cable bracket 14 can be an arched bracket or a beam-type bracket.

[0050] Secondly, this utility model also provides an excavator, such as Figure 1 As shown, the device includes: a lower carriage assembly 2, a main unit (not shown in the figure), an external cable 3, and a split-type power supply device 1 as provided in any of the above embodiments.
