Description

Technical Field

[0002] At present, engineering cutting machines are widely used in cutting operations of asphalt, cement pavements, etc. in many industries such as construction, highways, and bridges. A manually operated engineering cutting machine can control the cutting of a pavement at one depth. If the cutting depth needs to be changed, the operator generally presses down the handle of the cutting machine to change the cutting depth, but manual operation cannot ensure that the required cutting depths are consistent.

[0003] For example, Chinese Patent No. CN 108115848 A discloses a vehicle-mounted rock cutting machine, including: a cutting device provided with a cutting saw thereon; a mounting platform for mounting the cutting device; a feeding mechanism for providing feeding for the cutting operation of the cutting saw; a chassis disposed below the mounting platform; wherein: the mounting platform is hinged to the chassis in a manner capable of rotating in a plane perpendicular to the feeding direction of the cutting saw, and a first oil cylinder for driving the mounting platform to rotate is installed between the chassis and the mounting platform.

[0004] However, although the above vehicle-mounted rock cutting machine is hinged between the mounting platform and the chassis and the mounting platform is driven by an oil cylinder to keep the mounting platform in a horizontal state by adjusting the telescopic amount of the oil cylinder even on a laterally inclined ground, so that the cutting saw can perform vertical cutting, the cutting machine cannot accurately control the vertical cutting depth of the cutting saw, resulting in the problem of inconsistent cutting depths.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0028] As Figure 1 and Figure 2As shown, a cutting machine 10 with a lifting component according to an embodiment includes a carrier platform 100, a lifting component 200, a cutting component 300, and a hydraulic control system 400. The lifting component 200 includes a frame assembly 210, a hydraulic cylinder 220, and a displacement sensor (not shown in the figure). The cutting component 300 is rotatably disposed at one end of the frame assembly 210. The other end of the frame assembly 210 is rotatably connected to the carrier platform 100. The hydraulic control system 400 includes a cutting hydraulic motor 4010. The cutting hydraulic motor 4010 is disposed on the frame assembly 210, and the driving end of the cutting hydraulic motor 4010 is connected to the cutting component 300 for driving the cutting component 300 to rotate and cut. The telescopic end of the hydraulic cylinder 220 is connected to the carrier platform 100, and the fixed end of the hydraulic cylinder 220 is connected to the bottom surface of the frame assembly 210. The displacement sensor is disposed inside the hydraulic cylinder 220. The sensing end of the displacement sensor is connected to the piston rod 221 of the hydraulic cylinder 220. The output end of the displacement sensor is used to connect to the signal input end of the hydraulic control system 400. The hydraulic cylinder 220 is also used to connect to the signal output end of the hydraulic control system 400 to control the hydraulic cylinder 220 to lift the cutting component 300.

[0029] It can be understood that since the telescopic end of the hydraulic cylinder 220 is connected to the carrier platform 100, the fixed end of the hydraulic cylinder 220 is connected to the bottom surface of the frame assembly 210, and the carrier platform 100 is located on the ground, the hydraulic cylinder 220 drives the frame assembly 210 to rotate up and down around the carrier platform 100 when telescoping, ensuring that the cutting component 300 installed on the frame assembly 210 can adjust the cutting height, that is, ensuring that the cutting depth of the cutting component 300 is adjustable. Then, by connecting the driving end of the cutting hydraulic motor 4010 to the cutting component 300, the stability of the cutting component 300 during rotary cutting is ensured. Also, since a displacement sensor is provided inside the hydraulic cylinder 220, the operator can monitor the telescopic length of the piston rod 221 in the hydraulic cylinder 220 according to the actual cutting depth, and determine the cutting depth through the hydraulic flow regulation of the hydraulic control system 400 to ensure the consistency of the actual cutting depth. Also, due to the real-time monitoring of the displacement sensor, the situation of inaccurate cutting height adjustment is avoided, thereby improving the cutting efficiency of the cutting machine.

[0030] Such as Figure 1 and Figure 2As shown, in one embodiment, the hydraulic control system 400 further includes a hydraulic multi-way valve 4020, a first motor 4030, a first hydraulic pump 4040, and an open-type oil tank 4050. The hydraulic multi-way valve 4020 is disposed on the side wall of the vehicle frame assembly 210. The first motor 4030, the first hydraulic pump 4040, and the open-type oil tank 4050 are all disposed within the vehicle frame assembly 210. The rotating end of the first motor 4030 is connected to the rotating end of the first hydraulic pump 4040. The inlet of the first hydraulic pump 4040 is connected to the open-type oil tank 4050. Both ends of the hydraulic multi-way valve 4020 are respectively connected to the outlet of the first hydraulic pump 4040 and the hydraulic cylinder 220, and are used to control the oil pressure magnitude of the hydraulic cylinder 220. It can be understood that since the rotating end of the first motor 4030 is connected to the rotating end of the first hydraulic pump 4040, the first motor 4030 provides hydraulic power for the first hydraulic pump 4040, ensuring the high efficiency of power transmission. Also, since the inlet of the first hydraulic pump 4040 is connected to the open-type oil tank 4050 to suck the hydraulic oil in the open-type oil tank 4050, and then the hydraulic multi-way valve 4020 is used to control the oil pressure magnitude when the hydraulic cylinder 220 is lifting, so as to ensure the height adjustability of the hydraulic cylinder 220 when lifting the cutting assembly 300, thereby ensuring the consistency of the cutting depth. At the same time, the hydraulic oil in the open-type oil tank 4050 continuously exchanges heat with the external air during the circulation process, further improving the heat dissipation effect. In this embodiment, the first motor 4030 is a servo motor.

[0031] As Figure 1 and Figure 2 shown, in one embodiment, the hydraulic control system 400 further includes a balance valve 4060. The balance valve 4060 is disposed at the bottom of the vehicle frame assembly 210. The inlet and outlet of the hydraulic cylinder 220 are respectively connected to two main oil ports of the balance valve 4060. The control port of the balance valve 4060 is connected to one end of the hydraulic multi-way valve 4020, and the other end of the hydraulic multi-way valve 4020 is connected to the first hydraulic pump 4040. In this embodiment, since the inlet and outlet of the hydraulic cylinder 220 are respectively connected to two main oil ports of the balance valve 4060, the balance valve 4060 precisely adjusts the flow rate of the hydraulic oil entering and leaving the hydraulic cylinder 220, making the telescopic movement of the hydraulic cylinder 220 more stable, avoiding the situation that the telescopic instability of the hydraulic cylinder 220 is caused by too large a change in the hydraulic oil flow rate, thereby improving the safety and reliability of the hydraulic control system 400. Also, since the control port of the balance valve 4060 is connected to one end of the hydraulic multi-way valve 4020, and the other end of the hydraulic multi-way valve 4020 is connected to the first hydraulic pump 4040, the hydraulic oil of the first hydraulic pump 4040 enters the hydraulic multi-way valve 4020 to adjust the oil pressure magnitude, and then passes through the balance valve 4060 to adjust the telescopic amount of the hydraulic cylinder 220, so as to ensure the safety when the hydraulic cylinder 220 lifts the cutting assembly 300.

[0032] AsFigure 1 and Figure 2 As shown in Figure 1 and Figure 2 , in one embodiment, the hydraulic control system 400 further includes a second motor 4070, a second hydraulic pump 4080, and a closed-type oil tank 4090. The second motor 4070 and the second hydraulic pump 4080 are both disposed within the frame assembly 210, and the closed-type oil tank 4090 is disposed on the open-type oil tank 4050. The rotating end of the second motor 4070 is connected to the rotating end of the second hydraulic pump 4080. The oil outlet of the second hydraulic pump 4080 is connected to the oil inlet of the cutting hydraulic motor 4010, and the oil inlet of the second hydraulic pump 4080 and the oil outlet of the cutting hydraulic motor 4010 are both connected to the closed-type oil tank 4090. It can be understood that the closed-type oil tank 4090 is used to store hydraulic oil to meet the oil suction requirements of the second hydraulic pump 4080. Since the rotating end of the second motor 4070 is connected to the rotating end of the second hydraulic pump 4080, the second motor 4070 provides hydraulic power for the second hydraulic pump 4080, ensuring the high efficiency of power transmission. At the same time, by adjusting the rotation speed of the second motor 4070, the rotation speed and output torque of the cutting hydraulic motor 4010 are controlled, ensuring the linear speed of the cutting assembly 300, thereby improving the cutting efficiency of the cutting machine. In this embodiment, the second motor 4070 is a servo motor.

[0033] Further, in one embodiment, the closed-type oil tank 4090 and the open-type oil tank 4050 are of an integral structure, and the interiors of the closed-type oil tank 4090 and the open-type oil tank 4050 are separated by a partition.

[0034] As Figure 1 and Figure 2 shown in Figure 1 and Figure 2 , in one embodiment, the cutting assembly 300 includes a cutting blade 310 and a rotating mounting shaft 320. The rotating mounting shaft 320 is rotatably disposed within the frame assembly 210, and the driving end of the cutting hydraulic motor 4010 is connected to the rotating mounting shaft 320. Specifically, the driving end of the cutting hydraulic motor 4010 is fixedly connected to the rotating mounting shaft 320, and the cutting blade 310 is detachably connected to the side end of the rotating mounting shaft 320. In this embodiment, since the cutting blade 310 is detachably connected to the side end of the rotating mounting shaft 320, the replaceability of the cutting blade 310 is ensured, guaranteeing that the cutting blade 310 can be maintained in a timely manner.

[0035] In one embodiment, blade mounting portions 321 are provided at both side ends of the rotating mounting shaft 320, and the blade mounting portions 321 are used to mount the cutting blade 310. In this embodiment, since the blade mounting portions 321 are provided at both side ends of the rotating mounting shaft 320, the cutting blade 310 can be mounted at different positions according to different cutting requirements.

[0036] In one embodiment, the diameter of the cutting blade 310 is 500 mm - 2000 mm, ensuring that the cutting machine can replace cutting blades 310 of different sizes to meet different cutting requirements.

[0037] As Figure 1 and Figure 2 shown, in one embodiment, the cutting machine 10 with a lifting assembly further includes a protective cover 500. The protective cover 500 is detachably mounted on the outer wall of the vehicle frame assembly 210. The protective cover 500 is arranged corresponding to the cutting blade 310, and the protective cover 500 covers a part of the cutting blade 310. In this embodiment, the added protective cover 500 ensures the safety of the cutting blade 310 during cutting on the one hand, and prevents dust from splashing during cutting on the other hand.

[0038] In one embodiment, the cutting machine 10 with a lifting assembly further includes a heat dissipation assembly. The heat dissipation assembly is arranged inside the vehicle frame assembly 210. One end of the heat dissipation assembly is externally connected to a water source, and the other end of the heat dissipation assembly is arranged close to the cutting blade 310. In this embodiment, the heat dissipation assembly adopts a water-cooling method to achieve heat dissipation of the cutting blade 310 during cutting.

[0039] As Figure 1 and Figure 2 shown, in one embodiment, the hydraulic control system 400 further includes a mobile hydraulic motor 4100. The mobile hydraulic motor 4100 is arranged inside the carrier wheel 110 of the carrier platform 100. The driving end of the mobile hydraulic motor 4100 is connected to the carrier wheel 110 to drive the carrier wheel 110 to carry and move. In this embodiment, the carrier wheel 110 is a mobile track.

[0040] The present disclosure also provides a cutting device, including the cutting machine 10 with a lifting assembly described in any of the above embodiments.

[0041] Compared with the prior art, the present disclosure has at least the following advantages:

[0042] The cutting machine 10 with a lifting component according to the present disclosure. Since the telescopic end of the hydraulic cylinder 220 is connected to the carrier platform 100, the fixed end of the hydraulic cylinder 220 is connected to the bottom surface of the vehicle frame assembly 210, and the carrier platform 100 is located on the ground, the hydraulic cylinder 220 drives the vehicle frame assembly 210 to rotate up and down around the carrier platform 100 when telescoping, ensuring that the cutting component 300 installed on the vehicle frame assembly 210 can adjust the cutting height, that is, ensuring that the cutting depth of the cutting component 300 is adjustable. Further, since the driving end of the cutting hydraulic motor 4010 is connected to the cutting component 300, the stability of the cutting component 300 during rotary cutting is ensured; also, since a displacement sensor is provided inside the hydraulic cylinder 220, the operator can monitor the telescopic length of the piston rod 221 in the hydraulic cylinder 220 according to the actual cutting depth, and determine the cutting depth through the hydraulic flow regulation of the hydraulic control system 400 to ensure the consistency of the actual cutting depth. Also, due to the real-time monitoring of the displacement sensor, the situation of inaccurate cutting height adjustment is avoided, thereby improving the cutting efficiency of the cutting machine.

[0043] The above-described embodiments merely represent several implementation manners of the present disclosure, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
