Figure 2 It is a rear view of the working machine provided by the embodiment of the utility model. Figure 3 It is a top view of the working machine provided by the embodiment of the utility model.

[0032] See also Figures 1 to 4 An embodiment of the utility model provides a turntable assembly suitable for a working machine, the turntable assembly comprising a turntable body 100 , a counterweight 200 and a telescopic driving member 300 .
[0033] The turntable body 100 is a frame for mounting a lifting device such as a boom or a jib, and a lifting mechanism, a luffing mechanism, a rotating mechanism, a counterweight, a driver's cab, etc. The turntable body 100 is mounted on the chassis 900 of the operating machine through a rotating support device. In order to ensure the normal operation of the operating machine, the turntable body 100 has sufficient rigidity and strength.
[0034] The counterweight 200 is symmetrically installed on both sides of the turntable body 100. The counterweight 200 is located near the tail end of the turntable body 100. The counterweight 200 is rotatably connected to the turntable body 100, that is, the counterweight 200 can be rotatably connected to the turntable body 100 through a hinge.
[0035] One end of the telescopic driving member 300 is connected to the turntable body 100, and the other end of the telescopic driving member 300 is connected to the counterweight 200. The telescopic driving member 300 is suitable for driving the counterweight 200 to rotate around the connection point with the turntable body 100 to achieve position change. The telescopic driving member 300 is mainly used to achieve linear reciprocating motion, so as to push the counterweight 200 to rotate around the connection point with the turntable body 100, so that the counterweight 200 is unfolded at a certain angle, thereby adjusting the position of the counterweight 200 relative to the turntable body 100, and achieving the purpose of adjusting the center of gravity position of the chassis 900 of the working machine, so as to improve the stability of the working machine during operation.
[0036] The telescopic drive member 300 may be a linear drive such as a hydraulic cylinder or a pneumatic cylinder, and any drive or drive component that can achieve linear reciprocating motion may be used.
[0037] It can be understood that the turntable assembly provided by the embodiment of the utility model is symmetrically arranged on both sides of the turntable body 100, so that the counterweight 200 is rotatably connected to the turntable body 100, and a telescopic driving member 300 is arranged between the counterweight 200 and the turntable body 100. The telescopic driving member 300 can drive the counterweight 200 to rotate around the connection point with the turntable body 100 to achieve position change, so that the counterweight 200 is unfolded at a certain angle, thereby adjusting the position of the counterweight 200 relative to the turntable body 100, and achieving the purpose of adjusting the center of gravity position of the chassis 900 of the operating machine. Such an arrangement can not only increase the operating range of the operating machine and improve the stability of the operating machine during the operation; moreover, when the operating machine stops working, the telescopic driving member 300 can drive the counterweight 200 to rotate around the connection point with the turntable body 100 to achieve retraction, which can shorten the length of the entire operating machine and facilitate the transportation of the entire operating machine.
[0038] In some embodiments of the present invention, the turntable assembly further includes a displacement sensor (not shown in the figure), which is provided on the telescopic drive member 300 and is used to detect the displacement of the telescopic drive member 300. Therefore, the displacement of the telescopic drive member 300 can be adjusted according to the actual working conditions of the operating machine, and the counterweight member 200 can be more accurately controlled to be deployed at a certain angle, thereby further improving the stability of the operating machine during operation.
[0039] Specifically, the displacement sensor includes a magnetostrictive displacement sensor, which is disposed on the inner side or the outer side of the telescopic driving member 300 , and is used to detect the displacement of the telescopic driving member 300 .
[0040] For example, when the telescopic drive component 300 is a hydraulic cylinder or a pneumatic cylinder, a magnetostrictive displacement sensor is provided on the telescopic drive component 300 to measure the position of the piston of the telescopic drive component 300, thereby achieving accurate and reliable feedback of the position of the telescopic drive component 300, which is beneficial to effectively control the telescopic drive component 300 and facilitate automatic control of the turntable assembly.
[0041] When the displacement sensor is a magnetostrictive displacement sensor, there are two different installation methods for the magnetostrictive displacement sensor on the hydraulic cylinder or the air cylinder, namely, a built-in type or an external type.
[0042] When the magnetostrictive displacement sensor is installed externally, it is usually installed at the earring of the piston rod of the hydraulic cylinder or the gas cylinder. When the magnetostrictive displacement sensor is installed internally, the magnetostrictive displacement sensor is located inside the hydraulic cylinder or the gas cylinder. The specific installation method can be determined according to the actual use.
[0043] In addition to the above magnetostrictive displacement sensor, the displacement sensor may also be other displacement sensors, such as laser displacement sensors, etc. Any sensor that can realize displacement detection is acceptable.
[0044] In the embodiment of the present invention, during the process of the counterweight 200 rotating around the connection point with the turntable body 100 to achieve position change, the distance between the center of gravity of the counterweight 200 and the rotation center of the turntable body 100 gradually increases. When the counterweight 200 rotates around the connection point with the turntable body 100 to the position farthest from the rotation center of the turntable body 100, the counterweight effect of the counterweight 200 is most obvious, and at this time, it is equivalent to that the distance between the center of gravity of the counterweight 200 and the rotation center of the turntable body 100 is the largest.
[0045] The counterweight 200 configured in this way can reduce the distance between the center of gravity of the counterweight 200 and the rotation center (i.e., the rotation axis) of the turntable body 100 when the working machine stops working and the telescopic drive member 300 drives the counterweight 200 to rotate around the connection point with the turntable body 100 to achieve retraction, thereby shortening the length of the whole working machine and facilitating the transportation of the whole working machine. At the same time, when the working machine is performing aerial work, the telescopic drive member 300 can drive the counterweight 200 to rotate around the connection point with the turntable body 100 to achieve rotation and deployment, thereby improving the anti-overturning ability of the working machine and ensuring that the working machine has good stability.
[0046] Continue reading Figures 1 to 4 In some embodiments of the present invention, the turntable assembly further includes a telescopic arm assembly 400, which includes a telescopic arm body 410 and a driving body 420; one end of the telescopic arm body 410 is rotatably connected to the turntable body 100, and the other end of the telescopic arm body 410 is suitable for connecting a sling, which can be adaptively selected according to the type of the operating machine, for example, when the operating machine is a crane, the sling is a hook, and when the operating machine is a crane, the sling can be in a hanging basket, etc. The driving body 420 is installed on the turntable body 100 and is hinged to the telescopic arm body 410, and is used to drive the telescopic arm body 410 to perform a pitching motion.
[0047] An angle sensor 500 and a pull-rope displacement sensor 600 are provided on the telescopic arm body 410 . The angle sensor 500 is used to detect the pitch angle of the telescopic arm body 410 , and the pull-rope displacement sensor 600 is used to detect the extended length of the telescopic arm body 410 .
[0048] Continue reading Figures 1 to 4In some embodiments of the present invention, a steering angle sensor 700 and a tilt sensor 800 are provided on the turntable body 100. The steering angle sensor 700 is used to detect the rotation angle and steering direction of the turntable body 100, and the tilt sensor 800 is used to detect the inclination of the turntable body 100 relative to the horizontal position.
[0049] Furthermore, the turntable assembly also includes a control assembly, which is electrically connected to the angle sensor 500, the rope displacement sensor 600, the steering angle sensor 700 and the tilt sensor 800 respectively, and the control assembly is used to control the rotation of the counterweight 200 according to the corresponding information of the angle sensor 500, the rope displacement sensor 600, the steering angle sensor 700 and the tilt sensor 800.
[0050] The control component may be a microprocessor such as a programmable controller or a single-chip microcomputer. The control component may be composed of an integrated microcontroller unit or a plurality of microcontroller units connected together.
[0051] The turntable assembly provided by the embodiment of the utility model is configured by arranging a control assembly and a plurality of sensors on the turntable body 100 and the telescopic arm body 410. The control assembly is used to collect corresponding detection information of the plurality of sensors, and control the movement of the telescopic drive member 300 according to the collected detection information, so that the counterweight member 200 rotates a certain angle around the connection point with the turntable body 100 to open.
[0052] Since a magnetostrictive displacement sensor is provided on the telescopic driving member 300, the magnetostrictive displacement sensor measures the position of the piston of the telescopic driving member 300, thereby accurately and reliably feeding back the position of the telescopic driving member 300, and the movement of the telescopic driving member 300 can be controlled more accurately.
[0053] Therefore, the turntable assembly provided in the embodiment of the utility model can monitor in real time the length of the telescopic arm body 410, the angle of the telescopic arm body 410, the angle of the ground on which the operating machine is operating, and the rotation angle of the turntable body 100 compared to the driving state, so as to ensure that the operating machine can control the movement of the telescopic drive member 300 with a magnetostrictive displacement sensor to achieve the displacement of the counterweight 200 when the safety factor is met, thereby ensuring the safety of the operating process.
[0054] See also Figure 3 The counterweight 200 is rotated around the connection point with the turntable body 100 to a certain angle and opened to be in use. At this time, the telescopic arm body 410 of the operating machinery can be used to perform large-scale operations. The counterweight 200 can also be adjusted to adaptively shift and unfold according to the different lengths, amplitudes and loads of the telescopic arm body 410 to ensure that the safety factor of the operating machinery is within a reasonable range.
[0055] In addition, when the working machine is located on a slope, the inclination sensor 800 arranged on the turntable body 100 automatically detects the inclination of the turntable body 100 relative to the horizontal position, and feeds back the detected information to the control component. The control component controls the movement of the telescopic drive component 300 with a magnetostrictive displacement sensor to make the counterweight 200 adaptively move to expand or retract, thereby avoiding the working machine from tipping forward or backward and improving the stability of the working machine.
[0056] See also Figure 1 , Figure 2 and Figure 4 The counterweight 200 is stored in the side wall of the turntable body 100, which can effectively reduce the length of the entire operating machine and facilitate the transportation of the operating machine.
[0057] See also Figures 1 to 4 The working machine provided by the utility model comprises a chassis 900 and the above-mentioned turntable assembly, and the turntable assembly is rotatably arranged on the chassis 900. The working machine can be a crane, a hoist, a lift, etc.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
