Description

Technical Field

[0001] The invention relates to the technical field of road engineering equipment, and in particular to an opening structure of a side plate of a milling machine, a side plate and a milling machine. Background Art

[0002] With the continuous development of milling machines, there is a higher demand for the replacement efficiency of the milling drum. The current drum replacement method requires disassembly of the transmission door box, reducer and other components, and then the milling drum is pulled out from the bearing support end.

[0003] Since the milling drum needs to be pulled out from the bearing support end, the side panel needs to be designed to be an openable structure. The current mainstream side panel opening and closing methods mainly include the following two:

[0004] The first method: single hinge + screw fixing. Since directly opening the side panel will cause interference between the support flange and the bearing support, the side panel fixing screws and the screws on the support flange need to be removed, and then the support flange is taken out. Only then can the side panel be opened. In addition, due to the obstruction of the side slide plate, it is very difficult to remove the screws on the support flange. Sometimes, it is even necessary to remove the side slide plate before removing the support flange. The workload is large and it takes a long time, and it is impossible to quickly change the drum.

[0005] The second method: hinge + tapered hole flange, which uses a tapered hole flange to match the bearing support. When the side panel is opened, the flange and the bearing support can avoid each other and will not interfere with each other. However, the use of tapered hole flanges has very high requirements for its processing accuracy. It is necessary to ensure the coordination of the flange and the bearing, and also to ensure that the flange and the bearing will not interfere with each other during the rotation of the hinge.

[0006] Therefore, for those skilled in the art, how to provide a new opening structure for the side panel of the milling machine so that the side panel can be rotated out without removing the supporting flange, and at the same time the structure is simpler than the existing technology and is easier to process, is of more practical significance. Summary of the invention

[0007] In order to improve at least one of the above-mentioned technical problems, an object of the present invention is to provide an opening structure of the side panel of a milling machine, so that the side panel can be rotated out without removing the supporting flange. At the same time, the structure is simpler than the prior art and is easier to process.

[0008] Another object of the present invention is to provide a side plate of a milling machine.

[0009] Another object of the present invention is to provide a milling machine comprising the above-mentioned opening structure.

[0010] In order to achieve the above-mentioned objectives, the technical solution of the first aspect of the present invention provides an opening structure of the side plate of a milling machine, wherein a milling drum is arranged in the milling machine, and a supporting flange is arranged on the side plate, and the supporting flange and the bearing support of the milling drum are abutted against each other, and the opening structure comprises: a rotating member, which is used to rotate the side plate relative to the milling drum; a sliding member, a part of which is arranged in the sliding member, so that the side plate can be translated along the axial direction of the bearing support to move away from or close to the milling drum, and when the side plate is translated to a first preset position, the supporting flange and the bearing support can always remain non-contact when the side plate rotates relative to the milling drum, and when the side plate is translated to a second preset position, the supporting flange and the bearing support of the milling drum are abutted against each other; wherein, one of the sliding member and the rotating member is connected to the side plate, and the other is connected to the milling machine body.

[0011] Specifically, the opening structure provided by the technical solution of the first aspect of the present invention includes a connected sliding part and a rotating part, wherein the rotating part can make a translational motion relative to the sliding part, so that two parts respectively connected to the sliding part and the rotating part, such as the side panel and the milling machine body, can translate and rotate relative to each other.

[0012] Compared with the related technology, this solution increases the translational movement space of the side plate relative to the milling machine body by setting a sliding part, provides conditions for the separation of the side plate and the milling drum of the milling machine, limits the interference between the bearing support and the support flange, has a simple structure and is easy to install. At the same time, it does not require major modifications to the structure of the milling machine. The processing is relatively simple and the cost is low. When replacing the milling drum, there is no need to remove the side plate as a whole, which improves the replacement efficiency.

[0013] It can be understood that the sliding member has a certain length along the axial direction of the bearing support, so that the sliding of the side plate has a first preset position and a second preset position. When the side plate is in the second preset position, the support flange of the side plate and the bearing support of the milling drum are abutted against each other. When the side plate needs to be rotated, the side plate is translated to the first preset position relative to the milling machine body, so that the support flange and the bearing support of the milling drum are separated, and a certain gap distance is left between them. The gap distance provides a rotation space for the side plate, and the gap distance is large enough to make the side plate far enough away from the milling drum, so that the activity space for the side plate to rotate continues to exist, so that during the rotation of the side plate, the support flange and the bearing support can avoid each other and not contact each other, thereby greatly reducing the possibility of interference between the support flange and the bearing support. At the same time, after the side plate rotates relative to the milling machine body, there is enough space for the milling drum to be directly pulled out of the milling machine body, eliminating the work of removing the side plate or the support flange, and effectively improving the replacement efficiency of the milling drum.

[0014] In addition, the opening structure in the above technical solution provided by the present invention may also have the following additional technical features:

The end of the cylindrical part is gap-fitted with the long strip part so that the cylindrical part can translate along the length direction of the long strip part, and the long strip part can make a circular motion around the axis of the cylindrical part.

[0016] In the above technical solution, the sliding member includes a connecting portion, which is used to connect the side plate or the milling machine body, and makes the extension direction of the long strip member parallel to the axial direction of the bearing support.

[0017] In the above technical solution, the elongated component is a slide groove, the cylindrical component is a rotating shaft, the rotating shaft passes through the slide groove, and the axis of the rotating shaft is perpendicular to the length direction of the slide groove, and the two ends of the slide groove are adapted to the outer dimensions of the rotating shaft.

[0021] In addition, it is worth mentioning that the side panel provided with the above-mentioned opening structure can perform translational movement relative to the milling machine body, so that the side panel and the milling machine body are not limited to being connected only by rotation, but can also be connected in a sliding manner. Correspondingly, the opening method of the side panel is expanded, so that the side panel can be suitable for a variety of milling machines. At the same time, since the processing method of the opening structure is simple, it is conducive to maximizing standardization.

[0022] Among them, the side plate can also be provided with only the sliding part of the opening structure, and the bolts provided on the milling machine body serve as the rotating part of the opening structure. In this way, the modification amount of the milling machine body can be reduced and the modification cost can be reduced.

[0024] The milling machine provided by the technical solution of the third aspect of the present invention includes the opening described in any one of the technical solutions of the first aspect, and thus has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0025] In addition, it is worth mentioning that the milling machine in this solution can use its own rotating parts, such as bolts, to connect the sliding parts on the side panels, without the need to modify other structures, which can further reduce the modification cost.

[0026] In the above technical solution, the rotating part of the opening structure is a hinge structure; the hinge structure includes a hinge seat and a rotating shaft connected to the hinge seat, and the hinge seat is connected to the milling machine body; the sliding part includes a slide groove and a connecting part, part of the rotating shaft is vertically inserted into the slide groove, and the connecting part is connected to the side plate, so as to set the extension direction of the slide groove along the axial direction of the bearing support.

DETAILED DESCRIPTION

[0038] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0040] Refer to the following Figures 1 to 5 An opening structure, a side plate and a milling machine according to some embodiments of the present invention are described.

[0041] The opening structure 1 provided by the embodiment of the first aspect of the present invention comprises a rotating member 11 and a sliding member 12 , and the rotating member 11 is slidably connected to the sliding member 12 .

[0042] Embodiment 1

[0043] Specifically, Figure 1 As shown, the opening structure 1 includes a connected sliding member 12 and a rotating member 11, wherein the rotating member 11 can perform translational motion relative to the sliding member 12, so that two components respectively connected to the sliding member 12 and the rotating member 11, such as the side panel 2 and the milling machine body 3, can translate and rotate relative to each other.

[0044] In the case where a milling drum is provided in the milling machine, a support flange 21 is provided on the side plate 2, and the support flange 21 abuts against the bearing support 41 of the milling drum, the rotating member 11 is used to rotate the side plate 2 relative to the milling drum; a part of the rotating member 11 is provided in the sliding member 12, so that the side plate 2 can translate along the axial direction of the bearing support 41 to move away from or close to the milling drum; the sliding member 12 is provided with a connecting structure for connecting the side plate 2, and the rotating member 11 is provided with a connecting structure for connecting the milling machine body 3. At the same time, the sliding member 12 has a sufficient length, so that the side plate 2 can translate a sufficient distance relative to the milling machine body 3, so that after the side plate 2 translates in the direction away from the milling drum, there is sufficient space for movement between the support flange 21 and the bearing support 41, so that during the rotation of the side plate 2, the support flange and the bearing support always remain non-contact, thereby greatly reducing the possibility of interference between the support flange and the bearing support.

[0045] Compared with the related art, this solution increases the translational movement space of the side plate 2 relative to the milling machine body by setting a sliding part 12, provides conditions for the separation of the side plate 2 and the milling drum of the milling machine, limits the interference between the bearing support 41 and the support flange 21, has a simple structure and is easy to install. At the same time, it does not require major modifications to the structure of the milling machine, and the cost is low. When replacing the milling drum, there is no need to remove the side plate 2 as a whole, which improves the replacement efficiency.

[0046] Embodiment 2

[0047] On the basis of embodiment 1, further, the rotating member 11 includes a cylindrical component, and the sliding member 12 includes a long strip component adapted to the cylindrical component, and one axial end of the cylindrical component is clearance-matched with the long strip component, so that the cylindrical component can translate along the length direction of the long strip component, and the long strip component can make a circular motion around the axis of the cylindrical component.

[0048] Specifically, the rotating member 11 is provided with a portion for the sliding member 12 to rotate relative to it. By setting the portion of the rotating member 11 for connecting with the sliding member 12 to be cylindrical, the rotation of the sliding member 12 can be more convenient, thereby facilitating the opening process of the side panel 2 in a rotating manner. Similarly, the sliding member 12 is provided with a portion for the rotating member 11 to slide relative to it. By setting the portion of the sliding member 12 for connecting with the rotating member 11 to be long strips, the rotating member 11 can be translated along a fixed route, thereby limiting the opening route of the side panel 2 in translation. In this way, a clearance fit is formed between the sliding member 12 and the rotating member 11, so that the sliding member 12 and the rotating member 11 can move relative to each other, and the structure is simple and easy to set up. The cylindrical part can be a bolt, and the long strip part can be a guide groove, which is conducive to optimizing the structure and reducing costs.

[0049] Furthermore, the long strip component is the slide groove 122 , the cylindrical component is the rotating shaft 111 , the rotating shaft 111 passes through the slide groove 122 , and the axis of the rotating shaft 111 is perpendicular to the length direction of the slide groove 122 , and the two ends of the slide groove 122 are adapted to the outer dimensions of the rotating shaft 111 .

[0050] By setting the cylindrical component as the rotating shaft 111 and the long strip component as the slide groove 122, and the two ends of the slide groove 122 are adapted to the outer dimensions of the rotating shaft 111, a better clearance fit effect can be achieved, and the rotating shaft 111 is confined in the slide groove 122, which helps to improve the stability of the opening and closing structure and the stability of the relative movement between the side plate 2 and the body. The slide groove 122 can be a guide groove or a guide rail.

[0051] Embodiment 3

[0052] On the basis of the first or second embodiment, further, as Figure 1 As shown, the sliding member 12 includes a connecting portion 121, which is used to connect the side plate 2 or the milling machine body 3, and makes the extending direction of the long strip member perpendicular to the plane where the side plate 2 is located.

[0053] By setting the connecting portion 121, on the one hand, a connecting portion 121 is provided for the sliding member 12 to be installed with the side plate 2 or the milling machine body 3, thereby facilitating the installation of the sliding member 12; on the other hand, the connecting portion 121 limits the positional relationship between the guide groove and the side plate 2, thereby helping to limit the opening path of the side plate 2 in translational motion, making the opening more convenient and reducing the possibility of interference between the supporting flange 21 on the side plate 2 and the bearing support 41 of the milling machine.

[0054] Furthermore, a step surface is provided on the connection portion 121, and the step surface can play a better role in positioning the sliding member 12, so that the sliding member 12 is set at a fixed position relative to the side plate 2, so that the guide groove of the sliding member 12 is kept parallel to the axial direction of the bearing support during the movement of the side plate 2, which can further reduce the possibility of interference between the support flange 21 and the bearing support 41. At the same time, by providing the step surface, the positioning step during the installation process is omitted, so that the installation process of the sliding member 12 is simple and the installation efficiency is improved.

[0055] Embodiment 4

[0056] On the basis of the third embodiment, further, the number of the sliding members 12 is two, and the two sliding members 12 are respectively arranged at two axial ends of the rotating member 11 .

[0057] The opening and closing structure provided in this embodiment has a rotating member 11 and sliding members 12 respectively connected to the two ends of the rotating member 11. By setting two sliding members 12, the two ends of the rotating member 11 can be limited respectively, so that the translation movement of the rotating member 11 is more stable, so as to improve the stability of the opening and closing structure. Among them, the rotating member 11 can be a linear rotating shaft 111, which has a simple structure and is easy to install; the rotating member 11 can also be a rotating shaft 111 with two axial ends and a bending structure. The rotating shaft 111 with a bending structure can be more suitable for the shape of the side panel 2 or the milling machine body 3 to avoid interference during the opening process.

[0058] The side panel 2 provided in the embodiment of the second aspect of the present invention includes the opening structure 1 provided in the embodiment of the first aspect of the present invention.

[0059] Embodiment 5

[0060] On the basis of any of the above embodiments, further, Figure 2 As shown, the side plate 2 includes a side plate body 24 and a sliding member 12 of the opening structure 1 , and the sliding member 12 is used to cooperate with a rotating member 11 arranged on the milling machine body 3 .

[0061] The side panel 2 provided with the sliding member 12 in the present embodiment can perform translational movement relative to the milling machine body 3, so that the side panel 2 and the milling machine body 3 are not limited to being connected only by rotation, but can also be connected in a sliding manner. Correspondingly, the opening method of the side panel 2 is expanded, so that the side panel 2 can be suitable for a variety of milling machines. At the same time, the processing method of the sliding member 12 is simple, which is conducive to maximizing standardization.

[0062] In some other embodiments, the side plate 2 includes a side plate body 24 and a rotating member 11 of the opening structure 1, and the rotating member 11 is used to cooperate with a sliding member 12 provided on the milling machine body.

[0063] The milling machine provided by the embodiment of the third aspect of the present invention comprises the opening structure 1 provided by the embodiment of the first aspect of the present invention.

[0064] Embodiment 6

[0065] On the basis of any of the above embodiments, further, Figure 4 and Figure 5 As shown, the milling machine includes a milling machine body, in which a milling drum is arranged; a support flange 21 is provided on the side plate 2, and the support flange 21 and the bearing support 41 of the milling drum are abutted against each other to support the milling drum; the milling machine body and the side plate 2 are connected by an opening structure 1.

[0066] Specifically, Figure 4The side plate 2 on the milling machine is closed, the rotating member 11 is located at one end of the sliding member 12, the supporting flange 21 and the bearing support 41 of the milling drum are in abutment with each other, and the side plate 2 provides a stable support to the milling drum; Figure 5 This is the state when the side plate 2 on the milling machine is open, the rotating member 11 is located at the other end of the sliding member 12, the supporting flange 21 and the bearing support 41 of the milling drum are separated, and the milling drum can be taken out of the milling machine body for replacement.

[0067] The milling machine provided in this embodiment can use the rotating parts 11 provided therein, such as bolts, etc., to connect the sliding parts 12 on the side panels 2, without the need to modify other structures, which can further reduce the modification cost.

[0068] Embodiment 7

[0069] On the basis of Example 6, further, Figure 4 and Figure 5 As shown, the rotating part 11 of the opening structure 1 is a hinge structure 10; the hinge structure 10 includes a hinge seat 112 and a rotating shaft 111 connected to the hinge seat 112, and the hinge seat 112 is connected to the milling machine body; the sliding part 12 includes a slide groove 122 and a connecting part 121, a part of the rotating shaft 111 is vertically inserted into the slide groove 122, and the connecting part 121 is connected to the side plate 2, so as to set the extension direction of the slide groove 122 along the axial direction of the bearing support 41.

[0070] The opening structure 1 of the milling machine provided in this embodiment is a hinge structure 10, which is fixedly connected to the side panel 2 through the connecting portion 121 and fixedly connected to the milling machine body through the hinge seat 112, thereby making installation more convenient and improving the connection strength, thereby preventing the side panel 2 from shaking relative to the milling machine body and improving the stability of the opening structure 1.

[0071] Furthermore, a matching portion 22 is provided on the side panel 2, and the matching portion 22 is arranged on the side edge of the side panel 2 for connecting the opening structure 1; an avoidance space 23 is formed between the matching portion 22 and the side panel 2, and the avoidance space 23 is used to limit the interference between the side panel 2 and the hinge seat 112.

[0072] By providing the matching portion 22, the opening structure 1 is kept at a certain distance from the side panel body 24, thereby avoiding interference between the side panel body 24 and the opening structure 1 during the opening process, thereby making the opening and closing process smoother.

[0073] Embodiment 8

[0074] On the basis of Example 6 or Example 7, Figure 3As shown, further, the rotating member 11 of the opening structure 1 includes two coaxially arranged rotating shafts 111; when there are two sliding members 12, the two sliding members 12 correspond to the two rotating shafts 111 one by one and are connected.

[0075] The milling machine provided in this embodiment is provided with two opening structures 1, each of which includes a rotating shaft 111 and a sliding member 12, and the rotating shafts 111 of the two opening structures 1 are coaxially arranged. By providing two opening structures 1, they can be respectively arranged at the upper and lower ends of the same side of the side plate 2, so that the rotation and translation of the side plate 2 are more stable, so as to improve the use stability of the opening and closing structure. At the same time, a long rotating shaft 111 is taken out of two short rotating shafts 111, which reduces the length of the rotating shaft 111, and at the same time reduces the possibility of interference between the middle section of the omitted rotating shaft 111 and the milling machine body or other equipment, further improving the use reliability.

[0076] The following is a specific embodiment to illustrate the opening structure of the side panel of the milling machine provided by the present application, the specific structure and working principle of the side panel and the milling machine.

[0077] With the continuous development of milling machines, there is a higher demand for the replacement efficiency of the milling drum. The current drum replacement method requires the disassembly of the transmission door box, reducer and other components, and then the milling drum is pulled out from the bearing support 31 end. Since the milling drum needs to be pulled out from the bearing support end, the side panel 2 needs to be designed as an openable structure. The current mainstream side panel 2 opening and closing methods mainly include the following two types: 1. Single hinge + screw fixation. Since directly opening the side panel 2 will cause the flange to interfere with the bearing support 31, the side panel 2 fixing screws and the screws on the support flange 21 need to be removed, and then the support flange 21 is taken out. Only then can the side panel 2 be opened. 2. Single hinge + tapered hole flange, which uses a tapered hole flange to cooperate with the bearing support 31. When the side panel 2 is opened, the flange and the bearing support 31 can avoid each other and will not interfere.

[0078] However, the above two side panel 2 opening and closing methods have the following problems: for the combination structure of single hinge + screw fixing, due to the obstruction of the side slide plate, the screw removal process on the support flange 21 is very difficult, and sometimes it is even necessary to remove the side slide plate before removing the support flange 21. The workload is large and it takes a long time, and it is impossible to quickly change the drum. For the combination structure of single hinge + conical hole flange, the use of conical hole flange has very high requirements for its processing accuracy. It is necessary to ensure the coordination between the flange and the bearing, and it is also necessary to ensure that the flange and the bearing will not interfere with each other during the rotation of the hinge.

[0079] To this end, in view of the above limitations, the present application provides an opening structure 1 of the side panel 2, which allows the side panel 2 to be rotated out through a hinge without removing the supporting flange 21. The opening structure 1 is simple in structure and easy to manufacture.

[0080] Specifically, the round hole on the hinge rotating block of the side panel 2 is changed to a U-shaped hole to form a sliding part 12, which is then installed and matched with the hinge seat 112 and the rotating shaft 111. When it is necessary to change the drum, first remove the transmission box and the reducer, and then remove the fixing screws on the side panel 2. Before rotating the side panel 2, first translate the side panel 2 outward along the slide groove 122 of the sliding part 12. After confirming that the support flange 21 is completely disengaged from the bearing support 31, rotate the side panel 2. At this time, the support flange 21 and the bearing support 31 will not interfere with each other.

[0081] The opening structure 1 of the whole set of side panels 2 includes a side panel body 24, a hinge seat 112, a rotating shaft 111, a supporting flange 21 and a guide groove. Among them:

[0082] Side panel body 24: The side panel body 24 is provided with a countersunk hole penetrating through the thickness direction of the side panel body 24 for installing fixing screws. The fixing screws are used to fix the side panel body 24 and the milling machine body 3. Two guide grooves set at intervals are fixed on one side of the side panel body 24. The rectangular area between the two guide grooves is the avoidance space of the hinge seat 112. The middle position of the side panel body 24 is connected to the support flange 21.

[0083] Hinge seat 112: The hinge seat 112 is composed of a fixed plate and two rotating blocks. The fixed plate is used to fix the hinge seat 112, and the rotating blocks cooperate with the rotating shaft 111 to enable the side panel 2 to open and close.

[0084] Rotation axis 111: The rotation axis 111 passes through the two rotation blocks and the guide groove and serves as the rotation center.

[0085] Support flange 21: The support flange 21 is used as a connecting plate between the side plate 2 and the bearing support 31 to connect the side plate 2 and the bearing support 31.

[0086] Guide groove: It can be a slide groove 122, which is fixed on the side panel 2, located at both ends of the hinge seat 112, and cooperates with the rotating shaft 111. Its function is to translate the side panel 2 and then rotate it to open and close.

[0087] The opening process of the side panel 2 is as follows: Step 1: Remove the fixing screws; Step 2: Translate the side panel 2 to ensure that the support flange 21 is completely separated from the bearing support 31; Step 3: Open the side panel 2. In this way, this embodiment provides a combination structure of a slide slot 122 and a hinge structure 10, so that the side panel 2 is first translated and then flipped. After the side panel 2 is flipped, the milling drum can be directly pulled out from the milling machine body 3 without removing the support flange 21 or the side panel 2, etc., so that when replacing the milling drum, it can be replaced faster, improving work efficiency. At the same time, the overall structure is simple, the processing is convenient, the cost is low, and it has great use value.
