Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of carriage cleaning equipment, especially to the self-centering frame for carriage leftover cleaning. BACKGROUND

[0002] At present, train transportation as a clean transportation mode has been widely used in material transportation, such as transporting coal in the fields of steel and coal-fired power generation. When the train transports the material to the designated place, the unloading is carried out through the dumper, and the leftover in the carriage is cleaned through the carriage leftover cleaning machine to avoid resource waste.

[0003] In the prior art, the carriage leftover cleaning machine is usually positioned by the centering support to make the front and rear moving tracks of the carriage leftover cleaning machine coincide with the carriage axis to ensure the cleaning quality. For example, the utility model patent with publication (announcement) number CN213948389U discloses a carriage leftover cleaning device, which comprises a frame and at least two symmetrically arranged left and right positioning plates. The middle parts of the left and right positioning plates are rotatably installed on the frame through rotating shafts. The middle part of the frame is provided with a vertical slide rail. The leading ends of the left and right positioning plates are connected with the slide blocks in the slide rail. The trailing ends of the left and right positioning plates are provided with a top positioning wheel and a side wall positioning wheel. When the box body is placed in the carriage, the rolling surfaces of the top positioning wheel and the side wall positioning wheel respectively contact with the top and the inner side wall of the carriage side plate. However, it has the following technical problems:

[0004] Since the middle parts of the left and right positioning plates are rotatably installed on the frame through rotating shafts, the rotation amplitude of the two side positioning plates is prone to be too large, which makes it difficult to be connected in place at one time during the connection with the carriage side plate, and the positioning efficiency is low. In addition, the overall structure is complex and not easy to maintain. Utility model content

[0005] The embodiment of the present application provides a self-centering frame for carriage leftover cleaning, which has a simple overall structure, is convenient to maintain, and can also quickly complete self-centering positioning in the carriage.

[0006] This application provides a self-aligning frame for cleaning up leftover materials in a car body, including a connecting frame and a mounting frame. The connecting frame is fixedly mounted on the top of the leftover materials cleaning machine. The mounting frame includes a guide rod, a fixed frame, and at least two self-aligning wheel sets symmetrically arranged on the fixed frame. The guide rod extends vertically, and the connecting frame has a guide channel that slides with the guide rod. The self-aligning wheel sets include a top positioning wheel and a side positioning wheel. The side positioning wheel is arranged on the fixed frame in a manner that allows it to move elastically in the horizontal direction, so that when the top positioning wheel rests on the top of the side wall of the car body under its own weight, the side positioning wheel can elastically contact the inner side of the side wall of the car body, achieving elastic self-alignment.

[0007] In one possible implementation, the connecting frame is square and is formed by vertically connecting I-beams. Square steel is connected to each of the four corners of the connecting frame. The square steel extends vertically, and the steel cylinder of the square steel forms the guide channel. The guide rod is slidably engaged with the square steel.

[0008] In one possible implementation, the mounting bracket further includes two symmetrically distributed connectors, each of which is perpendicularly connected to the top ends of two adjacent guide rods.

[0009] In one possible implementation, both the guide rod and the connector are made of square steel.

[0010] In one possible implementation, the mounting frame is square, and the self-centering wheel set has four parts, respectively located at the four corners of the mounting frame.

[0011] In one possible implementation, the side positioning wheel is connected to the fixing frame via a vertical fixing shaft. The side positioning wheel and the vertical fixing shaft are connected by a bearing, allowing the side positioning wheel to rotate freely on the vertical fixing shaft. The fixing frame has a clearance notch for mounting the side positioning wheel. Guide rods and left and right limiting blocks are symmetrically arranged on the upper and lower sides of the clearance notch. The guide rods extend horizontally. The two ends of the vertical fixing shaft are slidably engaged with the guide rods on the upper and lower sides, respectively. A spring is sleeved on the guide rod, and the spring is elastically connected to the vertical fixing shaft.

[0012] In one possible implementation, one end of the spring is connected to the left limiting block and the other end is connected to the vertical fixing shaft, wherein the left limiting block is close to the inner side of the fixing frame.

[0013] Beneficial effects: compared with the prior art, the self-centering frame for cleaning the remaining materials in the vehicle compartment provided by the application makes the top positioning wheels respectively overlap the top of the side walls on both sides of the vehicle compartment by relying on the self-weight, and the self-centering positioning of the remaining material cleaning machine in the vehicle compartment can be quickly completed by relying on the elasticity due to the elastic connection of the side positioning wheels on both sides to the fixed frame, the positioning efficiency is high, and meanwhile, the overall structure of the self-centering frame is simple and convenient to maintain.

[0014] These and other objects, features and advantages of the present application will become apparent with reference to the following detailed description. BRIEF DESCRIPTION OF DRAWINGS
