Description

Technical Field

[0001] This utility model relates to the field of coal mine roadheader technology, specifically a roadheader anti-collision rotating tail section. Background Technology

[0002] A roadheader is short for a fully mechanized tunneling machine. It is a type of mechanized equipment that integrates multiple functions such as tunneling, rock loading, coal transportation, and even support and roadway anchoring. Mechanized roadheaders have been widely used in the tunneling production of coal and semi-coal-rock roadways in my country's coal mines.

[0003] Existing roadheaders, when performing wide-angle, large-section cutting operations, suffer from limitations in normal cutting operations due to the small swing amplitude of their transport coupling mechanism. Furthermore, the secondary conveyor belt is prone to deviating from its track, leading to the fall and accumulation of large amounts of coal ballast, posing safety hazards and impacting normal production. In addition, during operation, reversing and swaying of the roadheader can damage the machine itself and its downstream facilities. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to provide a collision-resistant rotating tail section for a roadheader.

[0005] This utility model is achieved through the following technical solution: A roadheader anti-collision rotating tail section includes a base, a rotating seat, a rotating bracket, and a buffer plate. A flange connecting plate is provided on the right side of the base, and the left side of the base is fixedly connected to the right side of the rotating seat. A drive motor is fixedly mounted on the top of the left side of the rotating seat. An internal transmission cavity is provided in the middle of the top of the rotating seat, and the output end of the drive motor extends into the internal transmission cavity. The output end of the drive motor is connected to a worm gear via a coupling, and the other end of the worm gear is rotatably mounted on the rotating seat. The rotating bracket is located directly above the rotating seat, and a rotating shaft is fixedly connected to the middle of the bottom of the rotating bracket. The rotating shaft extends into the internal transmission cavity and is rotatably mounted on the rotating seat. A worm wheel is fixedly mounted on the rotating shaft, and the worm wheel meshes with the worm gear. The buffer plate is located on the left side of the rotating seat, and both ends of the buffer plate are connected to the left side of the rotating seat via elastic components.

[0006] Furthermore, a bearing is installed at the other end of the worm gear, with the first bearing mounted on the rotating seat.

[0007] Furthermore, bearings are installed on the upper and lower parts of the shaft, and both bearings are mounted on the rotating seat.

[0008] Furthermore, the elastic component includes a sliding box, a sliding column, and a spring. The right end of the sliding box is fixedly connected to the left end of the rotating seat. The sliding column is slidably connected inside the sliding box. The left end of the sliding column is fixedly connected to the buffer plate. The spring is disposed inside the sliding box. The left end of the spring is fixedly connected to the right end of the sliding column, and the right end of the spring is fixedly connected to the right end of the sliding box.

[0009] Furthermore, a guide sliding sleeve is provided between the right end of the sliding column and the right end of the sliding box. The left end of the guide sliding sleeve is fixedly connected to the right end of the sliding column, and the right end of the guide sliding sleeve is fixedly connected to the right end of the sliding box. A spring is fitted onto the guide sliding sleeve.

[0010] This utility model is scientifically designed, structurally reasonable, easy to install, and convenient to use. It also has the functions of tail rotation and buffering and anti-collision, thus solving the problems of limited cutting operation of the tunnel boring machine due to the small swing amplitude of the transport linkage mechanism, deviation of the secondary transport belt from the track, and easy impact and damage during reversing and swinging.

Detailed Implementation

[0017] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present utility model and are not intended to limit its scope of protection. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this utility model pertains.

[0018] like Figures 1 to 4 As shown, this embodiment provides a collision-resistant rotating tail section for a roadheader, including a base 1, a rotating seat 2, a rotating bracket 3, and a buffer plate 4.

[0019] A flange connecting plate 5 is provided on the right side of the base 1. The flange connecting plate 5 is fixedly connected to the roadheader by bolts. The left side of the base 1 is fixedly connected to the right side of the rotating seat 2. A drive motor 6 is fixed on the top of the left side of the rotating seat 2. The drive motor 6 is an explosion-proof motor for coal mines. An internal transmission cavity 7 is provided in the middle of the top of the rotating seat 2. The output end of the drive motor 6 extends into the internal transmission cavity 7. The output end of the drive motor 6 is connected to a worm gear 8 through a coupling. The other end of the worm gear 8 is rotatably mounted on the rotating seat 2 through a bearing 9.

[0020] The rotating bracket 3 is located directly above the rotating seat 2. A rotating shaft 10 is fixedly connected to the bottom center of the rotating bracket 3. The rotating shaft 10 extends into the built-in transmission cavity 7. The upper and lower parts of the rotating shaft 10 are rotatably mounted on the rotating seat 2 via bearings 9. A worm gear 11 is fixedly mounted on the rotating shaft 10. The worm gear 11 is located in the built-in transmission cavity 7 and meshes with the worm 8.

[0021] A buffer plate 4 is positioned to the left of the rotating seat 2, with a safe distance between the buffer plate 4 and the rotating seat 2. Both ends of the buffer plate 4 are connected to the left end of the rotating seat 2 via elastic components. The elastic components include a sliding box 12, a sliding column 13, and a spring 14. The right end of the sliding box 12 is fixedly connected to the left end of the rotating seat 2. The sliding column 13 is slidably connected within the sliding box 12. A conventional limiting structure is provided between the right end of the sliding column 13 and the left end of the sliding box 12 to prevent the sliding column 13 from detaching from the sliding box 12. The left end of the sliding column 13 is fixedly connected to the buffer plate 4. The spring 14 is located within the sliding box 12, with its left end fixedly connected to the right end of the sliding column 13. The right end of the spring 14 is also fixedly connected to the sliding box 12. The right end of the sliding column 13 is fixedly connected; a guide sliding sleeve 15 is provided between the right end of the sliding column 13 and the right end of the sliding box 12. The left end of the guide sliding sleeve 15 is fixedly connected to the right end of the sliding column 13, and the right end of the guide sliding sleeve 15 is fixedly connected to the right end of the sliding box 12. A spring 14 is fitted on the guide sliding sleeve 15. The spring 14 is a compression spring. Under the action of the spring force of the spring 14, the sliding column 13 is pushed against the left end of the sliding box 12. At this time, the right end of the sliding column 13 and the left end of the sliding box 12 are abutted together by the limiting structure. The guide sliding sleeve 15 plays a guiding and stabilizing role for the sliding column 13 to slide in the sliding box 12 after being subjected to force, thereby making the entire buffer structure safer and more stable.

[0022] The anti-collision rotating tail section of the roadheader described in this embodiment requires the drive motor 6 to rotate when the tail section needs to rotate. The drive motor 6 drives the worm gear 8 to rotate via a coupling. The worm gear 8 drives the worm wheel 11 to rotate, which in turn drives the rotating shaft 10 to rotate. The rotating shaft 10 then drives the rotating bracket 3 to rotate, thereby adjusting the angle of the rotating bracket 3 and ultimately achieving the function of tail section rotation. This solves the problems of limited cutting operations of the roadheader due to the small swing amplitude of the transport connection mechanism and the deviation of the secondary transport belt from the track. When the tail section is impacted by reversing or swinging, the buffer plate 4 moves towards the rotating seat 2, the sliding column 13 slides relative to the sliding box 12, and the spring 14 is compressed and suctioned, thus absorbing and buffering the impact force and protecting the roadheader itself and the facilities behind it.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
