Description

Technical Field

[0001] This invention belongs to the field of road machinery technology, and specifically relates to a milling machine. Background Technology

[0002] Road milling machines are specialized mechanical equipment used for highway and urban road maintenance operations. They are mainly used for excavation and renovation of asphalt concrete pavements in highways, airports, docks, parking lots, etc., removal of road defects such as ruts, cracks, bumps, and road markings, roughening of cement pavements, and milling of surface misalignments.

[0003] The cab of a large milling machine is open at both ends, making the operating environment quite harsh. During operation, the operator needs to move left and right to operate from both sides. Furthermore, due to the need for visibility to the sides and rear, the operator must frequently move to observe the work area. This results in a high workload for the operator, and the operator's constant movement and exposure also pose certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a milling machine to solve the technical problems mentioned in the background art, such as the harsh operating environment and high workload for milling machine operators. To solve the above problems, this invention adopts the following technical solution: This invention provides a milling machine, comprising: The frame has a horizontally transverse operating platform, and the operating platform is provided with a guide rail section arranged horizontally and a sliding bracket that slides with the guide rail section. A flip-up bracket is provided inside the operating table. The end of the flip-up bracket is hinged to the sliding bracket. The flip-up bracket can flip relative to the sliding bracket with the hinge point at the end as the center. The cab is hinged at the bottom to the tilting bracket, and the cab is able to rotate relative to the tilting bracket with the hinge point at the bottom as the center. When the sliding bracket moves to the end of the guide rail, the front of the cab extends outside the control panel; when the sliding bracket moves between the middle and the end of the guide rail, the flipping bracket can flip relative to the sliding bracket so that the cab is placed flat inside the control panel.

[0005] Optionally, the guide rail includes a front slide rail and a rear slide rail disposed on both sides inside the operating table, and the sliding bracket includes a first slider and a second slider respectively slidably disposed on the front slide rail and the rear slide rail; The flip bracket includes a flip main board and a first end and a second end located at both ends of the flip main board; The first slider is connected to the first end of the flipping bracket via a support shaft. The second slider is provided with a sliding seat. The second end of the flipping bracket is hinged to the sliding seat. The sliding seat is also provided with a second rotary drive for driving the flipping bracket to flip.

[0006] Optionally, it also includes: The support frame has a rear slide rail mounted on it. The support frame is also equipped with a horizontally arranged rack. A gear and a hydraulic motor that are connected to the gear are mounted on the sliding seat. The gear meshes with the rack.

[0007] Optionally, the support frame is further provided with an upper slide rail located above the rear slide rail, and an upper slider is provided on the upper slide rail, with the upper end of the sliding seat connected to the upper slider.

[0008] Optionally, multiple shock absorbers are installed between the bottom of the support frame and the vehicle frame.

[0009] Optionally, it also includes: Limiting blocks are provided at both ends of the front slide rail.

[0010] Optionally, it also includes: A thin hydraulic cylinder is mounted on the sliding seat; a first limiting hole and a second limiting hole are provided at the second end of the flipping bracket; The telescopic end of the thin hydraulic cylinder can be inserted into the first limiting hole to limit the position when the cab is vertically positioned inside the control panel; the telescopic end of the thin hydraulic cylinder can be inserted into the second limiting hole to limit the position when the cab is horizontally positioned inside the control panel.

[0011] Optionally, it also includes: A shock-absorbing column is fitted around the outer ring of the support shaft; The pressure cap is installed at the flip-up bracket and presses against the shock-absorbing column.

[0012] Optionally, the tilting bracket has a first slewing drive in the middle, and the cab is mounted on the first slewing drive.

[0013] Optionally, it also includes: Shock-absorbing blocks are located on the side of the cab; The pedal is installed on the bottom wall of the control panel and is used to abut against the shock absorber when the cab is laid flat.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In operation, the enclosed cab of the milling machine of the present invention can slide and rotate, which can effectively improve the comfort of the operator's working environment. First, the cab can slide to both sides of the operating platform and extend beyond the operating platform, making it convenient for the driver to operate safely on both sides of the vehicle. In addition, the cab can also rotate, giving the driver a better field of vision to observe the sides and rear.

[0015] 2. In the transport state, the milling machine of the present invention can first adjust the position of the cab within the operating table by sliding the cab, and then can also flip it so that the cab is completely flat within the operating table, without the cab protruding outside the operating table. Thus, it not only does not increase the transport width of the whole machine, but also reduces the transport height of the whole machine. Attached Figure Description

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example 1

[0020] Combination Figure 1 This embodiment provides a milling machine, which includes: The frame 6 has a horizontally transverse operating platform, and the operating platform is provided with a guide rail section arranged horizontally and a sliding bracket 3 that slides with the guide rail section. A flip bracket 4 is disposed inside the operating table. The end of the flip bracket 4 is hinged to the sliding bracket 3. The flip bracket 4 can flip relative to the sliding bracket 3 with the hinge point at the end as the center. The cab 1 is hinged at the bottom to the tilting bracket 4, and the cab 1 can rotate relative to the tilting bracket 4 with the hinge point at the bottom as the center; the tilting bracket 4 is provided with a first rotary drive 8 in the middle, and the cab 1 is mounted on the first rotary drive 8.

[0021] Specifically, in this embodiment, the cab 1 is enclosed and has multiple degrees of freedom in multiple directions. First, it can rotate relative to the flipping bracket 4 with the bottom hinge point as the center. Second, it can flip relative to the sliding bracket 3 along with the flipping bracket 4. Third, it can slide laterally within the operating table along with the sliding bracket 3.

[0022] When the cab 1 is in operation, the tilting bracket 4 is locked in the tilting direction, and the cab 1 can only rotate and slide laterally. Furthermore, combined with... Figures 1 to 2 When the sliding bracket 3 moves to the end of the guide rail (combined with...) Figure 1 , Figure 1 The right side is the front of the vehicle body; Figure 1 This is a diagram showing the driver's cab moved to the far right of the control panel. Figure 2 (This is a schematic diagram showing the cab moving to the far left of the control panel.) When the cab 1 moves to the leftmost position of the control panel, the front part of the cab 1 extends beyond the control panel in the direction of movement, combined with... Figures 3 to 4 Combined with the rotation of the cab 1 itself ( Figure 3 The driver's cab 1 is located on the far right of the control panel and rotated to the right rear side. Figure 4 The cab 1 is located on the far left of the control panel and rotated to the left rear side, so that the driver can observe the front, rear and side views while ensuring safety. Usually when the milling machine is working, the driver needs to observe the front tracks on both sides and the material cart in front.

[0023] Combination Figure 5 Furthermore, when the cab 1 is in transport mode, as the sliding bracket 3 moves between the middle and end of the guide rail, the flipping bracket 4 can flip relative to the sliding bracket 3 to place the cab 1 flat within the operating table. In this embodiment, the height of the cab 1 is less than the width of the operating table. Therefore, based on the ability of the cab 1 to be laterally adjusted, the cab 1 can be directly flipped and placed flat within the operating table along with the flipping bracket 4. This ensures that in transport mode, the cab 1 will not extend beyond the operating table, and the width and height of the entire milling machine will not increase due to the cab 1. In other words, this installation structure of the cab 1 in this application allows the operator to obtain a better field of vision in a safe operating environment without increasing the size of the milling machine.

[0024] Furthermore, in this embodiment, the specific installation structure related to the cab 1 is as follows: Combination Figure 6 The guide rail includes a front slide rail 301 and a rear slide rail 302 located on both sides inside the operating table. The sliding bracket 3 includes a first slider 304 and a second slider 305 that are slidably disposed on the front slide rail 301 and the rear slide rail 302, respectively. Limiting blocks 310 are provided at both ends of the front slide rail 301 so that the first slider 304 will not slide out from both ends of the front slide rail 301.

[0025] The front slide rail 301 and the rear slide rail 302 are symmetrically arranged. With the cooperation of the first slider 304 and the second slider 305, the cab 1 can slide more stably in the area between the front slide rail 301 and the rear slide rail 302.

[0026] The flip bracket 4 includes a flip main board 402 and a first end and a second end provided at both ends of the flip main board 402; the first slider 304 is connected to the first end of the flip bracket 4 through a support shaft 403, and the first end of the flip bracket 4 can rotate relative to the first slider 304; the second slider 305 is provided with a sliding seat 309, and the second end of the flip bracket 4 is hinged to the sliding seat 309; the sliding seat 309 is also provided with a second rotary drive 401 for driving the flip bracket 4 to flip.

[0027] Combination Figure 7 and Figure 9 In this embodiment, a thin hydraulic cylinder 404 is provided on the sliding seat 309; at the same time, a first limiting hole 405 and a second limiting hole 406 are provided at the second end of the flipping bracket 4. When the cab 1 is in normal working condition, in order to prevent the cab 1 from overturning due to misoperation and affecting the driver's normal operation, the telescopic end of the thin hydraulic cylinder 404 can be inserted into the first limiting hole 405 so that the cab 1 remains vertical. When the cab 1 is in transport mode, the cab 1 needs to be kept within the operating platform area and cannot be extended or erected. At this time, the telescopic end of the thin hydraulic cylinder 404 can be inserted into the second limiting hole 406 so that the cab 1 is kept flat.

[0028] Combination Figures 6 to 8 Furthermore, the milling machine in this embodiment also includes: The support frame 5 is provided with the rear slide rail 302 mounted on it. The support frame 5 is also provided with a horizontally arranged rack 308. A gear 307 and a hydraulic motor 306 connected to the gear 307 are mounted on the sliding seat 309. The gear 307 meshes with the rack 308.

[0029] In this embodiment, the movement of the sliding seat 309 is controlled by the gear 307 and the rack 308. When the cab 1 needs to slide, the hydraulic motor 306 drives the gear 307 to move on the rack 308, thereby driving the cab 1 to slide laterally left and right.

[0030] The support frame 5 is also provided with an upper slide rail 303 located above the rear slide rail 302, and an upper slider 311 is provided on the upper slide rail 303. The upper end of the sliding seat 309 is connected to the upper slider 311.

[0031] Understandably, the bottom of the sliding seat 309 is slidably connected to the second slider 305 of the rear guide rail. There are two second sliders 305 here. The top of the sliding seat 309 is slidably connected to the upper slider 311 of the upper guide rail. Thus, the sliding seat 309 can be more stably restricted between the upper slide rail 303 and the rear slide rail 302 and slide horizontally.

[0032] Multiple shock absorbers 9 are installed between the bottom of the support frame 5 and the vehicle frame 6. At the same time, a shock absorber column 407 is also sleeved around the support shaft 403 connected to the first end of the flip bracket 4, and a pressure cap 408 is also provided on the flip bracket 4 to press on the shock absorber column 407.

[0033] The lower part of the support frame 5 is equipped with a shock absorber 9 and is connected to the frame 6. It can work with the shock absorber column 407 to effectively dampen the cab 1. Example 2

[0034] Similar to Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the flipping bracket 4 in this embodiment is U-shaped, the flipping main board 402 in the middle of the flipping bracket 4 is horizontal, and the two ends are vertical. The bottom of the cab 1 is installed on the first rotary drive 8 in the middle of the flipping bracket 4. The two ends of the flipping bracket 4 are vertical and are movably connected to the sliding seat 309 and the support shaft 403 respectively, so that the flipping bracket 4 can be flipped according to the work requirements.

[0035] Meanwhile, the driver's cab 1 is provided with a shock-absorbing block 2 on its side and a pedal 7 on the bottom wall of the control panel. When the tilting bracket 4 is tilted, the driver's cab 1 will be placed flat inside the control panel. At this time, the shock-absorbing block 2 will abut against the pedal 7 to form shock absorption and at the same time play a limiting role, so that the thin hydraulic cylinder 404 can cooperate with the second limiting hole 406 to limit the driver's cab 1.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
