[0036] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0038] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used to describe the relative positional relationship of components in the direction shown in the drawings or in the vertical, perpendicular or gravity direction.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] The utility model firstly provides a centralized oil filling device.

[0041] In one embodiment, referring to Figure 1 and attached Figure 2 As shown, the centralized oil filling device includes a mounting seat 1, a bracket 2, a driving member 3, a filling seat 4, a plurality of oil filling pipes (not shown in the figure), a first position detection member 5 and a control unit. The bracket 2 is movably arranged on the mounting seat 1 and has a free end. The driving member 3 is connected between the bracket 2 and the mounting seat 1, and can drive the bracket 2 to move relative to the mounting seat 1 to drive the free end to rise and fall. The filling seat 4 is arranged on the free end, and the input pipe openings of the plurality of oil filling pipes are all arranged on the filling seat 4. The first position detection member 5 is arranged on the mounting seat 1 and is located below the bracket 2. The first position detection member 5 can be triggered when the free end drops to a preset lower limit position and output a drop-in position signal. The control unit is respectively communicated with the driving member 3 and the first position detection member 5, and is used to control the driving member 3 to stop driving after receiving the drop-in position signal.

[0042] It can be understood that the centralized oil filling device of this embodiment can be applied to an excavator, the mounting seat 1 is installed at the bottom of the excavator's turntable, and the output pipe openings of multiple filling pipes are respectively connected to multiple oil filling ports of the excavator. Since the input pipe openings of multiple filling pipes are all set on the filling seat 4, when oil filling is required, the drive member 3 drives the bracket 2 to move relative to the mounting seat 1 to drive the free end together with the filling seat 4 set on the free end to descend. The operator only needs to fill the corresponding oil to the multiple filling pipes under the bottom of the excavator's turntable, without having to walk around the excavator frequently, which greatly reduces the oil filling time and improves the filling efficiency. Moreover, after the filling is completed, the drive member 3 can drive the bracket 2 to move relative to the mounting seat 1 to drive the free end together with the filling seat 4 to rise, so that the free end and the filling seat 4 are re-stored and hidden at the bottom of the excavator's turntable.

[0043] In addition, the centralized oil filling device includes a first position detection component 5 and a control unit. When the free end of the bracket 2 drops to a preset lower limit position, the first position detection component 5 is triggered and outputs a drop-in position signal. After receiving the drop-in position signal, the control unit controls the driving component to stop driving. With this arrangement, the drop-in position of the filling seat 4 can be accurately controlled when filling the oil.

[0044] Specifically, the oil filling pipe may be a flexible hose.

[0045] In this embodiment, the driving member 3 can be set as a hydraulic cylinder, and the extension and retraction action of the hydraulic cylinder can be controlled by the hydraulic system. The control unit is connected to the electric pump and the control valve in the hydraulic system. After receiving the signal of falling into place, the control unit sends a control instruction to the electric pump and the control valve in the hydraulic system, thereby controlling the driving member 3 to stop driving. It should be noted that controlling the extension and retraction action of the hydraulic cylinder by the hydraulic system is a conventional technical means in the art, so the specific structure and principle of the hydraulic system will not be described in detail here.

[0046] In this embodiment, the bracket 2 can be installed on the mounting base 1 in a rotatable or liftable manner, so that the lifting movement of the free end of the bracket 2 is achieved through the rotation or lifting movement of the bracket 2.

[0047] In one embodiment, referring to Figure 2 As shown, the first position detection member 5 is a travel switch, and a first trigger member 6 is provided at the bottom of the bracket 2. When the free end drops to a preset lower limit position, the first trigger member 6 touches the trigger end of the first position detection member 5, so that the first position detection member 5 is triggered and outputs a drop-in position signal.

[0048] In actual application, the operator can adjust and set the lower limit position of the free end descent by adjusting the position of the trigger end of the first position detection member 5 according to the actual use environment requirements, and the operation is relatively convenient and simple.

[0049] In another embodiment, the first position detection member 5 can also be a proximity switch, and a metal detection body is provided at the bottom of the bracket 2. When the free end drops to a preset lower limit position, the metal detection body enters the sensing area of ​​the first position detection member 5, thereby triggering the first position detection member 5 and outputting a drop-in-place signal.

[0050] Of course, in other embodiments, the first position detection component 5 may also be other detection elements with a position sensing function.

[0051] In one embodiment, the centralized oil filling device also includes a second position detection component 7, which is arranged on the mounting seat 1 and located above the bracket 2. The second position detection component 7 can be triggered and output a rising position signal when the free end rises to a preset upper limit position. The control unit is communicated with the second position detection component 7 and is used to control the driving component 3 to stop driving after receiving the rising position signal.

[0052] In this way, after the oil filling is completed, the bracket 2 is driven by the driving member 3 to move relative to the mounting seat 1 to drive the free end together with the filling seat 4 to rise, and the limit position of the free end and the filling seat 4 can be accurately controlled.

[0053] In one embodiment, referring to Figure 2 As shown, the second position detection member 7 is a travel switch, and a second trigger member 8 is provided on the top of the bracket 2. When the free end rises to a preset upper limit position, the second trigger member 8 touches the trigger end of the second position detection member 7, so that the second position detection member 7 is triggered and outputs a rising position signal.

[0054] In another embodiment, the second position detection member 7 can also be a proximity switch. A metal detector is provided on the top of the bracket 2. When the free end rises to a preset upper limit position, the metal detector enters the sensing area of ​​the second position detection member 7, thereby triggering the second position detection member 7 and outputting a rising position signal.

[0055] Of course, in other embodiments, the second position detection component 7 may also be other detection elements with a position sensing function.

[0056] In one embodiment, referring to Figure 1 As shown, the bracket 2 is provided with a pipe clamp support 9 and a plurality of pipe clamps (not shown) arranged side by side on the pipe clamp support 9, and the plurality of oil filling pipes are clamped on the plurality of pipe clamps one by one. In this way, when the free end of the bracket rises or falls, the plurality of pipe clamps restrict the positions of the plurality of oil filling pipes, thereby preventing the plurality of oil filling pipes from being worn due to friction with each other.

[0057] In one embodiment, referring to Figure 1 As shown, the centralized oil filling device also includes an input unit 10, which is communicatively connected to the control unit and can receive input information and generate control instructions. The control instructions include an ascending instruction and a descending instruction. The control unit is used to control the driving member 3 to drive the bracket 2 to move relative to the mounting seat 1 after receiving the ascending instruction, so as to drive the free end to rise. The control unit is also used to control the driving member 3 to drive the bracket 2 to move relative to the mounting seat 1 after receiving the descending instruction, so as to drive the free end to descend.

[0058] Specifically, the input unit 10 can be configured as a pull-rope switch. In actual application, the operator pulls the pull-rope switch to control the free end of the bracket 2 to rise or fall.

[0059] In other implementations, the input unit 10 may also be a touch screen or a smart terminal.

[0060] In one embodiment, referring to Figure 1 and attached Figure 2 As shown, the bracket 2 is hinged on the mounting base 1, and the driving member 3 is a telescopic driving member, and its two ends are respectively hinged to the mounting base 1 and the bracket 2. In this way, through the telescopic action of the driving member 3, the bracket 2 can be driven to rotate relative to the mounting base 1, thereby realizing the lifting and lowering of the free end.

[0061] Furthermore, the bracket 2 has a first end and a second end in the length direction, the hinge between the bracket 2 and the mounting seat 1 is located between the first end and the second end and is arranged adjacent to the second end, and the first end is a free end. In this arrangement, compared with the prior art in which the hinge between the bracket 2 and the mounting seat 1 is arranged at the end of the bracket 2, the bracket 2 of this embodiment has a larger turning radius and a smaller turning angle, so that the sudden change of speed caused by the quick return characteristic of the mechanism can be avoided.

[0062] In one embodiment, referring to Figure 1 As shown, the centralized oil filling device also includes a locking member 11, which can be switched between a locked state and an unlocked state. In the locked state, the locking member 11 limits the rotation of the bracket 2 relative to the mounting seat 1, and in the unlocked state, the locking member 11 releases the restriction on the bracket 2.

[0063] In actual application, when there is no need to add oil, the locking member 11 is used to limit the rotation of the bracket 2 relative to the mounting seat 1, so as to avoid accidents caused by the failure of the driving member 3 or the bracket 2, which may cause the free end to drop unexpectedly. For example, when the driving member 3 adopts a hydraulic cylinder, oil leakage occurs in the hydraulic system that controls the hydraulic cylinder, which may cause the hydraulic cylinder to extend and retract, thereby causing the bracket 2 to rotate, causing the free end of the bracket 2 and the filling seat 4 to drop unexpectedly. The limiting effect of the locking member 11 can effectively avoid this situation, thereby improving the structural reliability.

[0064] Specifically, the locking member 11 can adopt a locking pin, which is movably arranged on the bracket 2 or the mounting base 1, and a corresponding locking hole is opened on the bracket 2 or the mounting base 1. The locking pin is plugged into the locking hole to limit the rotation of the bracket 2 relative to the mounting base 1. The restriction can be released by pulling the locking pin out of the locking hole.

[0065] The utility model also provides an excavator, comprising a turntable and the above-mentioned centralized oil filling device, wherein the mounting seat 1 is mounted at the bottom of the turntable.

[0066] The above are only preferred implementation modes of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0067] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0068] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
