Problems solved by technology

[0002] At present, the underground service vehicles all adopt the central hinge swing mode. Since the central swing frame and the rear frame are hingedly connected, the rear frame swings together as a whole when swinging, the swing inertia is large, the swing form is complex, and the size of the middle hinge is large. Increased wheelbase leads to large turning radius and poor passability

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as Figure 1-4 As shown, a swing frame for an underground scraper includes: a front beam 1, a rear beam 2, a connecting plate 3, a hollow support 4, a first pin shaft 5, and a second pin shaft 6;

[0017] The front beam 1 is welded on the front frame, and the rear beam 2 is also welded on the front frame; both the front beam and the rear beam are rectangular plates;

[0018] The connecting plate 3 is arranged between the front beam 1 and the rear beam 2, and the bottom surface of the connecting plate is concave;

[0019] The hollow support 4 is a rectangular seat surrounded by four vertical plates. The top of the hollow support 4 is covered with a sealing plate 7 with a central opening. The hollow support 4 is fixed on the top of the connecting plate 3. The front and back of the hollow support 4 Both ends are respectively provid...

Abstract

The invention discloses a swing frame for an underground scraper. The swing frame comprises a front beam, a rear beam, a connecting plate, a hollow support, a first pin shaft and a second pin shaft, wherein the connecting plate is arranged between the front beam and the rear beam; the hollow support is fixed on the connecting plate; one end of the first pin shaft is fixedly connected with the front beam, and the other end of the first pin shaft extends into the hollow support through a through hole formed in one end of the hollow support; and one end of the second pin shaft is fixedly connected with the rear beam, and the other end of the second pin shaft extends into the hollow support through a through hole formed in the other end of the hollow support. The swing frame is simple and convenient to install and maintain and safe and reliable to use; the axle distance of the swing frame is shortened in comparison with that of a central hinged swing frame; and the axle distance is short,and the minimum turning radius can be reduced, so that the maneuverability and passability are improved.

Description

technical field [0001] The invention relates to the technical field of mining machinery and equipment, in particular to a swing frame for an underground scraper. Background technique [0002] At present, the underground service vehicles all adopt the central hinge swing mode. Since the central swing frame and the rear frame are hingedly connected, the rear frame swings together as a whole when swinging, the swing inertia is large, the swing form is complex, and the size of the middle hinge is large. The wheelbase increases, resulting in a large turning radius of the vehicle and poor passability. Contents of the invention [0003] Aiming at the deficiencies in the prior art above, the present invention provides a safe, reliable and practical swing frame for underground scrapers. [0004] The present invention is achieved through the following technical solutions. [0005] A swing frame for an underground scraper, characterized in that the swing frame includes: a front bea...
