[0036] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0037] In the prior art, roadheaders usually use crawler devices to achieve movement in roadways. If the geological conditions of the roadway are relatively poor, when the roadheader cuts coal and rock masses in the roadway, relatively large vibrations will occur in the crawler structure. As a result, it is easy to cause the crawler device to shake, affecting the stability of the overall operation of the roadheader.

[0038] To overcome the defects in the prior art, the present application provides a roadheader support device and a roadheader. The roadheader support device includes a telescopic member and a support structure. The support structure includes a support plate and a hinge assembly. The support plate is hinged to the telescopic member through the hinge assembly;

[0039] The telescopic member is used to be arranged on the body mechanism of the roadheader. The telescopic member telescopically drives the support plate to move relative to the body mechanism, so that the support plate supports against the top in the roadway. The telescopic member extends and retracts to enable the support plate to support against the top of the roadway. After the support plate supports against the roadway, the body mechanism is fixed. In this case, when the roadheader cuts coal and rock masses in the roadway, the shaking of the body mechanism is reduced, improving the stability of the roadheader during the tunneling operation.

[0040] The following will describe the content of the present invention in detail with reference to the drawings, so that those skilled in the art can understand the content of the present invention more clearly and in detail.

[0041] Figure 2 It is a schematic diagram of the roadheader support device provided by an embodiment of the present application.

[0042] See Figure 2 As shown, a roadheader support device provided by the present application is applied to a roadheader and includes a telescopic member 100 and a support structure 200. The support structure 200 includes a support plate 210 and a hinge assembly 220. The support plate 210 is hinged to the telescopic member 100 through the hinge assembly 220.

[0043] The telescopic member 100 is used to be arranged on the body mechanism 600 of the roadheader. The telescopic member 100 telescopically drives the support plate 210 to move relative to the body mechanism 600, so that the support plate 210 supports against the top in the roadway.

[0044] Exemplarily, the telescopic member 100 is an oil cylinder. In this embodiment, the telescopic end of the telescopic member 100 is the top. The hinge assembly 220 is arranged at the telescopic end, and the support plate 210 is connected to the top of the hinge assembly 220. Preferably, in this embodiment, the support plate 210 is circular, and the circular support plate 210 can avoid bumps at the corners.

[0045] It should be noted that the telescopic end of the telescopic member 100 extends upward, and the support plate 210 moves in a direction away from the body mechanism 600. More specifically, the support plate 210 is lifted upward, and the support plate 210 abuts against the top of the roadway, thereby achieving the support effect to solve the problem of shaking when the roadheader cuts coal and rock masses in the roadway.

[0046] Specifically, the support device of the present application is mainly used to solve the problems of cutting large cross-sections (over 20 ㎡), high hardness (above f8), large inclination (above 8°), semi-rock and full-rock roadways; as can be seen from the above, the support plate 210 is hinged to the telescopic end through the hinge assembly 220. Due to the hinge characteristics of the hinge assembly 220 itself, it has flexibility. Therefore, the support plate 210 can be finely adjusted in angle. The support plate 210 makes an adaptive angle adjustment according to the top of the roadway with different flatness, realizing the close fit between the support plate 210 and the top of the roadway, and enhancing the support stability of the support device.

[0047] In some embodiments, referring to Figure 3 as shown, the hinge assembly 220 includes a first base 221 and a ball head seat 223.

[0051] It should be noted that the sleeved and movable connection between the ball head seat 223 and the groove forms a wrapped contact. The wrapped contact has a large contact area, and the large contact area effectively ensures the support strength of the ball head seat 223 on the first base 221; in addition, the wrapped contact enables a large adjustable range of the angle of the support plate 210, improving the adaptability of the support plate 210 to the top of the roadway with different flatness.

[0052] In some embodiments, the hinge assembly 220 further includes at least one first rib 222, and both the first base 221 and the support plate 210 are connected to the first rib 222.

[0053] Exemplarily, the number of the first ribs 222 can be one or more, which is not limited herein; preferably, the first rib 222 is in the shape of a right triangle. One right-angled side of the first rib 222 is connected to the bottom surface of the support plate 210, and the other right-angled side is connected to the side wall of the first base 221. In this way, the first rib 222 forms a triangular support for the support plate 210, improving the support stability of the support plate 210.

[0054] In some embodiments, the number of the first ribs 222 is four, and the four first ribs 222 are arranged around the circumference of the first base 221.

The double-ear hinge seat is disposed at the telescopic end, and the single-ear hinge seat is disposed at the bottom of the support plate 210. The double-ear hinge seat is hinged to the single-ear hinge seat, thus realizing the hinge connection between the telescopic member 100 and the support plate 210.

[0064] In some embodiments, the support device further includes a plurality of anti-slip teeth 300. The anti-slip teeth 300 are disposed on the side of the support plate 210 away from the telescopic member 100, and the anti-slip teeth 300 are used for grasping and supporting on the inner top of the roadway.
