Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical operation tools for construction and highway engineering, and mainly relates to a longitudinal and transverse positioning bracket. Background Technology

[0002] Road milling machines are one of the main types of machinery used in asphalt pavement maintenance and construction, and one of the main pieces of equipment used in asphalt concrete pavement maintenance and construction. They are mainly used for excavation and renovation of asphalt concrete pavement in highways, urban roads, airports, freight yards, etc. They can also be used to remove defects such as road bulges, oil waves, textures, and ruts. In addition, they can be used to excavate road potholes and trenches, as well as roughen cement pavements and mill out misalignments.

[0003] Milling the damaged old pavement with a road milling machine and then laying a new surface layer is the most economical and modern maintenance method. It is widely used in urban municipal roads and highway maintenance projects because of its high work efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good maneuverability, and the ability to directly recycle the milled old material.

[0004] The milling chamber of a milling machine contains a rapidly rotating milling drum. Several cutting tools are fixed to the surface of the drum. The old material particles produced after milling the road surface need to be collected and transported using a specialized device, typically a discharge plate. Because the discharge plate continuously throws hard road surface particles onto a designated conveyor belt during operation, with a conveying capacity of several hundred cubic meters per hour, the rate of wear is astonishing. Furthermore, the mechanical impact of the road surface particles as the milling drum rotates severely tests the stability and fixation of the discharge plate.

[0005] Therefore, a robust and non-loosening longitudinal and transverse positioning bracket for installing the material discharge plate is urgently needed. Utility Model Content

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 3 As shown, this embodiment provides a longitudinal and transverse positioning bracket, including a bracket 20. The bracket 20 is a metal forging product with a rectangular cross-section. The bracket 20 has a front side 28 and a back side 28.1. The front side 28 of the bracket 20 has four inwardly recessed slots. The four slots are independently set and not connected to each other, arranged in a cross shape, and any two slots are separated by a certain distance. The top of the four slots has an upper side length, and the bottom has a lower side length. The upper side length is greater than the lower side length, thus forming a draft angle, which is conducive to smooth demolding.

[0029] In this embodiment, the four slots include a first slot 22, a second slot 23, a third slot 24, and a fourth slot 25, wherein the first slot 22, the third slot 24, and the fourth slot 25 have open ends that pass through the first side 200, the third side 202, and the second side 201. The first slot 22 opens with the first side 200 as a reference and has a first slot surface 22.1, a second slot surface 22.2, a third slot surface 22.3, and a fourth slot surface 22.4; the second slot 23 opens with the front surface 28 as a reference and has a fifth slot surface 23.1, a sixth slot surface 23.2, a seventh slot surface 23.3, an eighth slot surface 23.4, and a ninth slot surface 23.5; the third slot 24 opens with the third side 202 as a reference and has a tenth slot surface 24.1, an eleventh slot surface 24.2, a twelfth slot surface 24.3, and a thirteenth slot surface 24.4; the fourth slot 25 opens with the second side 201 as a reference and has a fourteenth slot surface 25.1, a fifteenth slot surface 25.2, a sixteenth slot surface 25.3, and a seventeenth slot surface 25.4. When the length and width of the support are limited, setting an open end on the slot makes it easier to clean up the residue accumulated inside the slot.

[0030] In this embodiment, a reinforcing rib 29 is provided on the back surface 28.1 of the bracket 20. The reinforcing rib 29 extends rearward from the contact surface 21, and the cross-section of the reinforcing rib 29 is triangular. The force direction of the bracket 20 is F, and the force is applied from front to back. The reinforcing rib 29 increases the bottom width and contact area of ​​the bracket 20, thereby enhancing its stability.

[0031] In this embodiment, the center of the bracket 20 is provided with a first fixing hole 26 and a second fixing hole 26.1 that penetrate the bracket 20 from front to back. The first fixing hole 26 and the second fixing hole 26.1 intersect with the third slot 24 and the fourth slot 25 respectively, and are used to connect the matching material discharge plate by bolts 40.

[0032] like Figures 4 to 5 As shown, the material discharge plate 10 has a first connecting surface 17 and a second connecting surface 17.1, which penetrate the material discharge plate 10 and are used for fitting and assembling with the bracket.

[0033] In this embodiment, the positioning blocks of the discharge plate 10 include a first positioning block 12, a second positioning block 13, a third positioning block 14, and a fourth positioning block 15. The first positioning block 12 includes a first positioning surface 12.1, a second positioning surface 12.2, a third positioning surface 12.3, a fourth positioning surface 12.4, and a fifth positioning surface 12.5. The second positioning block 13 includes a sixth positioning surface 13.1, a seventh positioning surface 13.2, an eighth positioning surface 13.3, a ninth positioning surface 13.4, and a tenth positioning surface 13.5. The third positioning block 14 includes an eleventh positioning surface 14.1, a twelfth positioning surface 14.2, a thirteenth positioning surface 14.3, a fourteenth positioning surface 14.4, and a fifteenth positioning surface 14.5. The fourth positioning block 15 includes a sixteenth positioning surface 15.1, a seventeenth positioning surface 15.2, an eighteenth positioning surface 15.3, a nineteenth positioning surface 15.4, and a twentieth positioning surface 15.5.

[0034] like Figures 6 to 7 As shown, the bracket 20 is used to fix and support the material discharge plate 10. The positioning surfaces of the first positioning block 12, the second positioning block 13, the third positioning block 14, and the fourth positioning block 15 are respectively fitted and assembled with the groove surfaces of the first groove 22, the second groove 23, the third groove 24, and the fourth groove 25 of the bracket 20. Bolt 40 passes through the first connecting surface 17 and the second connecting surface 17.1 of the discharge plate 10, and is connected in series with the first fixing hole 26 and the second fixing hole 26.1 of the bracket 20, respectively. The back surface 16 of the discharge plate 20 is in contact with the front surface 28 of the bracket 20. Bolt 40 is locked using a fastening nut 50, which presses the back surface 28.1 of the bracket 20. In the above process, 17 positioning surfaces are in contact with 17 slot surfaces. The cross-shaped positioning method restricts all six degrees of freedom (up, down, left, right, front, and back). Therefore, the connection between the discharge plate 10 and the bracket 20 is quite stable and can maintain a durable rigid connection even under severe vibration and impact. Furthermore, the discharge plate 10 can be installed in conjunction with the bracket 20 after rotating 180 degrees. This greatly extends the service life of the discharge plate 10.

[0035] The working principle of this embodiment will be further explained below:

[0036] like Figures 8 to 9 As shown, the discharge plate 10 and the support 20 are in contact with the roller surface 61 through the mating surface 21 of the support 20. The bottom annular surface 27 is welded and fixed to the surface 61 of the roller 60. The roller 60 rotates rapidly around the center O in the rotation direction M. The discharge plate 10 obtains working transport power in this rotational motion. The multiple discharge surfaces 11, 11.5, 11.6, 11.1, 11.2, 11.3, and 11.4 continuously scoop up and throw the crushed particles from the road surface onto the associated designated conveyor belt. It has stable performance and high working efficiency.

[0037] The longitudinal and transverse positioning bracket provided in this embodiment has a large area and multi-angle mating surface, which strengthens the support and increases the stability. It can firmly position and fasten the material discharge plate, and can easily and quickly replace the material discharge plate, thereby improving the efficiency and quality of related operations, reducing the labor intensity of operators, and greatly saving construction costs.

[0038] It should be noted that the accompanying drawings in this embodiment are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0039] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
