Description

Technical Field

[0001] This utility model relates to the technical field of rail transit construction equipment, specifically to a column cutter head crossbeam structure for a ballast cleaning and screening machine. Background Technology

[0002] A ballast cleaning and screening machine is a type of mechanical equipment used for railway maintenance and upkeep. Its main function is to excavate and screen the ballast on the railway track bed, and backfill the qualified ballast onto the track, while also adding some new ballast to restore the performance of the track bed.

[0003] The ballast cleaning and screening machine's excavation mechanism includes an excavation mechanism and a ballast lifting mechanism. The excavation mechanism, through its unique cutterhead system, penetrates deep into the railway track bed to excavate the ballast from the bottom of the sleepers to a certain depth. The ballast lifting mechanism is responsible for extracting, transporting, and repaving the ballast excavated by the excavation mechanism.

[0004] The main structure of the excavating mechanism includes a column and a crossbeam. A rotating mechanism is installed above the column, driving the excavating mechanism to rotate and penetrate deep into the railway track bed. A cutterhead system is located on the outside of the crossbeam, driven by a drive assembly to excavate the ballast. During ballast excavation, the excavating mechanism experiences excavation resistance from the ballast. This resistance changes continuously during the excavation process, generating dynamic shear forces on the excavating mechanism. These shear forces can lead to damage or failure of the connection structure between the column and the crossbeam; therefore, a reasonable structural design is necessary to improve the structural connection strength of the excavating mechanism. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a column cutter head crossbeam structure for a ballast cleaning and screening machine. This invention ensures the shear strength of the connection structure between the column and the crossbeam of the excavation mechanism, thus avoiding structural damage during ballast excavation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A column cutter head crossbeam structure for a ballast cleaning machine includes a crossbeam and a column connected to the upper part of one end of the crossbeam. A drive assembly is provided on one side of the column, and a column base plate is provided at the lower end of the column. The column base plate and the drive assembly are both connected to the crossbeam through a first connecting plate. A first mounting groove and a second mounting groove are provided on the upper part of the first connecting plate. The column base plate is located in the first mounting groove, and the drive assembly is located in the second mounting groove.

[0008] In the above solution, the column, drive assembly, and crossbeam are fixedly connected by the first mounting plate, ensuring the stability of the structural connection. The first mounting plate is provided with a first mounting groove and a second mounting groove. The column is placed in the first mounting groove through the column base plate, and the drive assembly is placed in the second mounting groove. The inner wall of the mounting groove provides support for the column and the drive assembly, improving the shear strength of the connection structure between the column, the drive assembly, and the crossbeam, and preventing the structure from being damaged by shear force when cleaning ballast.

[0009] Furthermore, the drive assembly includes an externally disposed sleeve, with a pair of connectors on the periphery of the sleeve, and fixing plates on both sides of the column. The column and the connectors are connected via the fixing plates. By connecting the column to the connectors on the sleeve via the fixing plates, the connection between the column and the drive assembly is achieved, improving the overall structural integrity.

[0010] Furthermore, a fixing plate is provided around the sleeve, and the end face of the fixing plate is located within the second mounting groove. The driving assembly is connected to the cross frame through the fixing plate, and the end face of the fixing plate is placed in the second mounting groove, where the inner wall of the second mounting groove provides support for the sleeve, thereby further improving the shear strength of the structure.

[0011] Furthermore, the crossbeam includes an upper end plate connected to the first connecting plate. One end of the upper end plate extends outward along the length of the crossbeam to form a support end, and the drive assembly is located above the support end. Since one end of the drive assembly is connected to a sprocket, the sprocket is located outside the crossbeam due to the outward extension of the support end along the crossbeam direction, thereby reducing the length of the crossbeam and saving manufacturing costs.

[0012] Furthermore, the drive assembly has an output end, and the support end and the first connecting plate have corresponding through holes, through which the output end passes. A sprocket is connected via the output end, and the output end passing through the through hole positions the sprocket below the support end, thereby driving the digging chain connected to the crossbeam to rotate.

[0013] Furthermore, the column is equipped with several suspension connecting plates. These suspension connecting plates enable connection with the ballast lifting mechanism.

[0014] Furthermore, an anti-wear plate is provided below the crossbeam. This anti-wear plate prevents the ballast from directly abrading the crossbeam and causing damage.

[0015] Furthermore, a notch is provided on the first connecting plate. The notch increases the weld length between the first connecting plate and the crossbeam, thereby improving the connection strength.

[0016] Furthermore, a flange is provided at the upper end of the column. The column is connected to an external rotating mechanism through the flange, thereby enabling the digging mechanism to rotate and penetrate deep into the railway track bed to clean the ballast.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting a first mounting plate to fix the column, drive assembly, and cross frame together, the stability of the structural connection is ensured. A first mounting groove and a second mounting groove are set on the first mounting plate. The column is placed in the first mounting groove through the column base plate, and the drive assembly is placed in the second mounting groove. The inner wall of the mounting groove provides support for the column and drive assembly, which improves the shear strength of the connection structure between the column, drive assembly, and cross frame and avoids the structure being damaged by shear force when cleaning ballast.

[0019] 2. By connecting the column to the connector on the sleeve through the fixing plate, the connection between the column and the drive assembly is realized, which improves the overall structure.

[0020] 3. The notch increases the weld length between the first connecting plate and the crossbeam, further improving the connection strength between the column and the crossbeam. Attached Figure Description

[0030] The following is combined Figures 1 to 5 The column cutter head cross frame structure of a ballast cleaning machine provided by this utility model will be described in detail through specific embodiments and application scenarios.

[0031] A column cutter head crossbeam structure for a ballast cleaning machine includes a crossbeam 1 for mounting the cutter head system and a column 2 connected to the upper part of one end of the crossbeam 1. The column 2 includes a column base plate 201, column side plates 202, a first column panel 203, and a second column panel 204. Two column side plates 202 are fixedly connected to the upper surface of the column base plate 201. The side ends of the two column side plates 202 are fixedly connected to the first column panel 203. The second column panel 204 is located between the two column side plates 202 and fixedly connected to them. Three reinforcing ribs 3 are also fixedly connected between the first column panel 203 and the column base plate 201, further improving the connection strength between the column 2 and the column base plate 201. A drive assembly 6 is provided on the side of the column 2 near the second column panel 204, and the drive assembly 6 is used to drive the cutter head system. The column base plate 201 and the drive assembly 6 are both fixedly connected to the cross frame 1 through the first connecting plate 4. The first connecting plate 4 is provided with a first mounting groove 5 and a second mounting groove 12. The column base plate 201 is located in the first mounting groove 5, and the drive assembly 6 is located in the second mounting groove 12.

[0032] By setting the first connecting plate 4 to fix the column 2 and the drive assembly 6 to the cross frame 1, the stability of the structural connection is ensured. The first connecting plate 4 is provided with a first mounting groove 5 and a second mounting groove 12. The column 2 is placed in the first mounting groove 5 through the column base plate 201, and the drive assembly 6 is placed in the second mounting groove 12. The inner wall of the mounting groove has a supporting effect on the column 2 and the drive assembly 6, which improves the shear strength of the connection structure between the column 2, the drive assembly 6 and the cross frame 1, and avoids the structure being damaged by shear force when cleaning the ballast.

[0033] Furthermore, such as Figure 1 and Figure 5 As shown, the drive assembly 6 includes an externally disposed sleeve 7. A pair of connectors 8 are provided on the periphery of the sleeve 7. The connectors 8 include a second connecting plate 801 and a third connecting plate 802. The two second connecting plates 801 are fixedly connected to the side wall of the sleeve 7, and the third connecting plate 802 is fixedly connected to the second connecting plate 801. Fixing plates 10 are provided on both sides of the column 2. The column 2 and the connectors 8 are connected through the fixing plates 10, which improves the overall structure of this utility model.

[0034] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, a fixing plate 701 is provided around the sleeve 7. The end face of the fixing plate 701 is located in the second mounting groove 12. Bolt holes are provided on the fixing plate 701. The fixing plate 701 is fixed to the first connecting plate 4 by bolts, ensuring the connection strength between the drive assembly 6 and the first connecting plate 4. At the same time, the fixing plate 701 is placed in the second mounting groove 12. The side wall of the second mounting groove 12 provides support for the sleeve 7. Since the drive assembly 6 is connected to the column 2 as a whole through the fixing plate 10, the shear strength of the connection between the column 2 and the crossbeam 1 is further increased.

[0035] Furthermore, such as Figure 1 As shown, the crossbeam 1 includes an upper end plate 101, a frame 103, and a lower end plate 104. The upper surface of the upper end plate 101 is welded to the first connecting plate 4. One end of the upper end plate 101 extends outward along the length of the crossbeam 1 to form a support end 102, and the drive assembly 6 is located above the support end 102. Since one end of the drive assembly 6 is connected to a sprocket, which drives the cutter head system mounted on the crossbeam 1, the drive assembly 6, through the support end 102, positions the sprocket outside the frame 103 of the crossbeam 1, thereby reducing the length of the frame and saving manufacturing costs. Furthermore, compared to the prior art where the sprocket is positioned inside the frame 103, positioning the sprocket outside the frame 103 facilitates assembly and disassembly.

[0036] Furthermore, such as Figure 1 and Figure 3 As shown, the drive assembly 6 has an output end, and the support end 102 and the first connecting plate 4 have corresponding through holes 14, through which the output end passes. The output end is connected to a sprocket, and the output end passes through the through hole 14 so that the sprocket is located below the support end 102, thereby driving the cutter head system set on the crossbeam 1 to work.

[0037] Furthermore, such as Figure 2 As shown, the column 2 is equipped with two pairs of suspension connecting plates 9, each including a first suspension plate 901 and a second suspension plate 902. The first suspension plate 901 is located above the second suspension plate 902, and is L-shaped. The vertical portion of the first suspension plate 901 is fixed to the column side plate 202 by bolts. The second suspension plate 902 is welded to the column side plate 202. The bolted connection between the first suspension plate 901 and the column side plate 202 enables the first suspension plate 901 to be detachable, facilitating connection with an external ballast lifting mechanism. When connecting to the ballast lifting mechanism, the first suspension plate 901 and the second suspension plate 902 are connected to the suspension fixedly connected to the ballast lifting mechanism, thus connecting the column 2 to the ballast lifting mechanism. During installation, the suspension is first fixed to the second suspension plate 902, then the first suspension plate 901 is installed to the column 2 with bolts, and finally the first suspension plate 901 is fixed to the suspension with bolts. The connection between the excavation mechanism and the ballast lifting mechanism is realized through the suspension connecting plate.

[0038] Furthermore, such as Figure 1 and Figure 3 As shown, an anti-wear plate 13 is provided below the cross frame 1. When the excavation mechanism cleans the ballast, the ballast will directly contact the cross frame 1 and damage the cross frame 1. Replacing the cross frame 1 after it is damaged is costly. By setting the anti-wear plate 13, the ballast can be prevented from directly contacting the cross frame 1 and damaging it.

[0039] Furthermore, such as Figure 1 and Figure 4 As shown, a notch 401 is provided on the first connecting plate 4. The notch 401 increases the weld connection length between the first connecting plate 4 and the cross frame 1, thereby improving the connection strength between the first connecting plate 4 and the cross frame 1.

[0040] Furthermore, such as Figure 5 As shown, a flange 11 is provided at the upper end of the column 2. The column 2 is connected to an external rotating mechanism through the flange 11, thereby realizing the rotation of the excavating mechanism and allowing the excavating mechanism to penetrate into the railway track bed for ballast cleaning.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
