Abstract

The patent of the utility model relates to a structure that is used for the suspension type rack rail card rail traction engine of underground mining. The tractor (1) body (2) consists of an upper part (3) and a lower part (8) which are hinged together at one end of the body (2) by means of a pin (7) with a horizontal axis of rotation (O), and at the other end they are connected by means of a hydraulic cylinder (12) transverse to the running rail (5). The pin (7) is located above a plane (P) passing through the rotation axis (O1) of the vertical gear (9) and parallel to the running rail (5), and the hydraulic cylinder (12) is located substantially perpendicular to the running rail (5) in the meshed state of the vertical gear (9) and the rack (6) of the rail (5).

Description

Suspension type rack rail clamping rail traction locomotive

Technical Field

The patent of the utility model relates to a suspension type rack rail card rail traction engine relates to a be used for underground mining transportation suspension type rack rail card rail traction engine especially.

Background

In the patent application p.426456 a suspended rack and rail truck tractor is disclosed, which consists of two basic units hinged to each other, the mutual position of which is determined by the connected elevators. The upper part of the car body is suspended on the suspended running rail by a rolling unit, and is equipped with a connection clamp for fixing the suspended rail car train at the end thereof. And the lower part of the body of the traction locomotive is provided with a vertical gear driven by a slow speed driver and meshed with a rack on the lower surface of the running guide rail. At one end, the upper body portion is connected to the lower portion by a hinge pin located below the horizontal rotary shaft tie rod bracket, and adjustment of the connection of the lower portion to the upper body portion is performed by lifters installed at opposite ends of the two portions. The lifter is preferably a screw lifter, the working stroke of which ensures that the rack on the rack is disengaged or intermeshed with the teeth of the lower gear of the vehicle body. This configuration of the tractor ensures effective engagement of the toothed elements and facilitates safe operation of the suspended rack and rail tractor. Some of the inconveniences associated with this arrangement are the increased frequency of cleaning the tractor mechanism when operating the screw elevator in conditions where there is a significant amount of dust in the air.

Also known for example from PL 219522B 1 polish patent specification is a friction-geared suspended track mining vehicle, the tractor of which can be engaged with or disengaged from the rack of the running track. The fork with a connector cooperating with a horizontally arranged hydraulic cylinder is used for engaging and disengaging the tractor and the running rail rack, so that the moving unit containing the gear is moved upwards relative to the vehicle body to engage, and the downward movement is disengaged from the rack. In conditions of dust flying, such tractors tend to become contaminated and jam the moving units on the car body and increase with wear of the link and guide elements, which requires an increased range of maintenance and service work.

Disclosure of Invention

The object of the present invention is to develop a tractor structure which will be simpler and not affected by major pollution in the working environment, without increasing the frequency and range of maintenance and repair work.

The solution is a suspension type rack rail clamping rail traction locomotive, the upper part of a locomotive body is suspended on a running rail through a rolling unit, one end of the locomotive body is hinged to the lower part of the locomotive body provided with a horizontal rotating vertical gear through a horizontal rotating shaft, and the gear is meshed with a rack of the running rail through a lifter positioned at the opposite hinged ends of the upper part and the lower part of the locomotive body during running. The essence of the patent of the utility model is that the horizontal rotation axis of the pin of the articulated connection upper and lower part of the vehicle body is located above the plane passing through the vertical gear rotation axis and parallel to the running track, and the lifter is a hydraulic actuator transverse to the running track, and its upper ear articulates in the arm of the upper part of the vehicle body, also articulates in the holder of the lower part of the vehicle body through the lower ear.

The utility model discloses a main advantage is simple structure, and is low to operational environment's pollution sensitivity. The cylinder is positioned almost vertically at the level of the hinge connection of the upper and lower body parts, which enables the drive gear to engage and disengage with a small stroke of the cylinder (i.e., with minimal exposure of the core box surface). The position of the pin that connects the upper and lower parts of the tractor body, where the hydraulic cylinder may be subjected to an uncontrolled increase of the hydraulic pressure in its cylinder, improves the working condition of the hydraulic cylinder very significantly.

Detailed Description

A suspended rail traction vehicle 1 (fig. 1, 2) has a vehicle body 2, an upper part 3 of which passes through a rolling unit 4 (fig. 1, 2)3) Is movably suspended on a running rail 5 with a rack 6 at the bottom. The upper part 8 of the body 2 is hinged to the upper part 3 of the body 2 by means of a pin 7 with a horizontal axis of rotation O. The pin 7 is located parallel to the rotation axis O passing through a vertical gear 9 connected to a drive 10 (fig. 3, 4) of the traction engine 1₁Above the plane P of the running rail 5, from the end of the car body 2 near the gripper 11, to the link of the not shown suspended car component. At the other end of the body 2, transversely to the running rail 5, there is a hydraulic cylinder 12 which is articulated by means of an upper lug 13 with a pin 14 in an arm 15 (fig. 3, 4) of the upper part 3 and by means of a lower lug 16 also with a pin 16a in a holder 17 of the lower part 8 of the body 2. The sliding of the hydraulic cylinder 12 (fig. 1) causes the lower part 8 of the car body 2 to rotate on the pin 7 and lift upwards, so that the vertical gear 9 of the traction vehicle 1 meshes with the rack 6, so that the traction vehicle 1 can move along the running track 5. Subsequently, the hydraulic actuator 12 (fig. 2) is extended, causing the lower part 8 of the body 2 to descend, which causes the pinion 9 to disengage from the rack 6 of the running rail 5, so that the traction vehicle 1 ends up along the running rail 5. When the vertical gear 9 is engaged to the rack 6 of the running rail 5, the hydraulic cylinder 12 is in a position substantially perpendicular to the running rail 5.
