Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a support frame for a ballast cleaning device. Background Technology

[0002] Ballast is a buffer layer located between railway tracks and earthen subgrade. It is used to distribute and cushion the weight and impact of trains, ensuring safe and smooth train operation.

[0003] Traditional ballast removal equipment typically uses a slag removal chain to drive the cleaning mechanism, thereby clearing the ballast to one side of the track. The slag removal chain on existing ballast removal equipment is usually restricted by guide wheels. Since ballast may fall onto the slag removal chain during operation, there is a risk that the slag removal chain may fall off during operation, thus affecting the ballast removal efficiency. Utility Model Content

[0007] Furthermore, the auxiliary support mechanism includes support mounting seats respectively located on both sides of the guide bracket, a support rotating shaft located between the two support mounting seats, and an auxiliary support roller rotatably mounted on the support rotating shaft and in contact with the inner wall of the slag removal chain.

[0008] Furthermore, the auxiliary support roller is provided with a limiting groove that is compatible with the slag removal chain, and the slag removal chain is located in the limiting groove.

[0011] Furthermore, the guide bracket includes a crossbeam located at the bottom of the connecting frame, connecting pipes located at both ends of the crossbeam, and a guide beam and a drive mounting beam respectively connected to the two connecting pipes. The support mechanism is rotatably mounted on the crossbeam and the guide beam respectively, and the auxiliary support mechanism is mounted on the crossbeam and the guide beam.

[0012] Furthermore, each end of the crossbeam is provided with a first mounting groove adapted to the support mechanism, and the end of the guide beam is provided with a second mounting groove adapted to the support mechanism. The guide mechanism is rotatably installed in the first mounting groove and the second mounting groove respectively.

[0014] Furthermore, the support mechanism includes several rotating shafts located within the guide brackets, and limiting rollers rotatably mounted on the rotating shafts and rotating along the axis of the rotating shafts; the limiting rollers are provided with support rings for supporting the rotation of the slag removal chain.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. The support mechanism of this utility model is installed on the guide bracket.

[0029] Example 1.

[0030] like Figure 1-7 As shown, the present invention provides a support frame for a ballast cleaning device, including a connecting frame 1 connected to an excavator, a guide bracket 2 located at the bottom of the connecting frame 1, several support mechanisms rotatably mounted on the guide bracket 2 for supporting the rotation of the slag removal chain 3, and an auxiliary support mechanism mounted on the guide bracket 2 for assisting in supporting the slag removal chain 3.

[0031] The connecting frame 1 of this utility model is connected to the excavator boom, thereby allowing the excavator to move the cover cleaning device for ballast cleaning. The guide bracket 2 is installed at the bottom of the connecting frame 1, which facilitates the support of the slag removal chain 3, allowing the chain to rotate. The support mechanism is installed on the guide bracket 2, which supports the slag removal chain 3 to rotate along the outer wall of the guide bracket 2. The support mechanism also restricts the slag removal chain 3 to prevent it from falling off during operation and affecting the cleaning efficiency of the ballast cleaning equipment. The support mechanism also reduces the friction between the slag removal chain 3 and the guide bracket 2. An auxiliary support mechanism is installed on the guide bracket 2, which further supports the slag removal chain 3 and restricts its position during operation to prevent it from falling off.

[0032] During use, the connecting frame 1 moves under the drive of the excavator, while the slag removal chain 3 rotates on the support mechanism under the drive of the drive equipment, thereby clearing the ballast under the track.
