DETAILED DESCRIPTION

[0027] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

On the structure 2, the first grinding disc 31 is detachably connected to the first abutment mechanism 33, the secondary rust removal device 4 includes a second lifting mechanism 41, a first bidirectional electric push rod 42 and two second grinding discs 43, and connecting brackets 421 are installed on the two output ends of the first bidirectional electric push rod 42, and the connecting brackets 421 are provided with second rust removal motors 422, and the second rust removal motor 422 is installed with a second abutment mechanism 44 for always abutting the second grinding disc 43 against the side wall of the track, the second lifting mechanism 41 is arranged in the installation cavity 12, the first bidirectional electric push rod 42 is horizontally connected to the second lifting mechanism 41, and the two second grinding discs 43 are detachably connected to the two second abutment mechanisms 44 respectively.

[0029] It is worth noting that the driving system includes a control box, a power box and a travel motor. The above is the prior art. The power is provided by the power box, and the travel motor drives the track wheel 13 to rotate. Of course, the power supply of all devices is provided by the power box.

[0030] The utility model enables two preliminary rust removal devices 3 to move downward synchronously through a first lifting mechanism 2. The first lifting mechanism 2 includes a U-shaped frame 21, a first lifting electric push rod 22, a cross plate 23 and two first mounting plates 24. Guide rods 25 are provided on both sides of the bottom of the cross plate 23. The first mounting plate 24 is provided with guide holes that cooperate with the guide rods 25. The U-shaped frame 21 is arranged on the top of the vehicle plate 1. The first lifting electric push rod 22 is vertically arranged on the top of the U-shaped frame 21. The cross plate 23 is horizontally installed on the output end of the first lifting electric push rod 22. The two first mounting plates 24 are respectively installed in the two mounting cavities 12. The two first rust removal motors 32 are respectively connected to the bottoms of the two guide rods 25.

[0031] The cross plate 23 is driven downward by the first lifting electric push rod 22, and the cross plate 23 can drive the two guide rods 25 to move downward. The cooperation between the guide rods 25 and the guide holes can improve stability. After the guide rods 25 move downward, they can drive the first rust removal motor 32 to move downward synchronously, and the first grinding disc 31 also moves downward and abuts against the upper surface of the rail. The first rust removal motor 32 drives the first grinding disc 31 to rotate, and the first grinding disc 31 can perform rust removal operations on the upper surface of the rail.

[0032] The first grinding disc 31 can be tightly abutted against the upper surface of the rail through the first abutment mechanism 33. The first abutment mechanism 33 includes a first connecting disc 331, a slide sleeve 332 and a second connecting disc 333. The bottom of the first connecting disc 331 is provided with a plurality of first screws 3311, and the first screw 3311 is mounted with a first nut 3312 matched therewith. A sliding disc 334 is slidably provided in the slide sleeve 332, and a first spring 335 is provided on the top of the sliding disc 334. There is a first slide column 336, and the first slide column 336 passes through the bottom of the slide sleeve 332. The top of the slide sleeve 332 is provided with a plurality of first through holes for the first screw 3311 to pass through. The top of the first grinding disk 31 is provided with a plurality of second screws 311. The second screw 311 is installed with a second nut 312 that matches it. The second connecting disk 333 is provided with a plurality of second through holes for the second screw 311 to pass through. The first connecting disk 331 is connected to the output end of the first rust removal motor 32.

[0033] After the first grinding disc 31 abuts against the upper surface of the rail, the first lifting electric push rod 22 continues to drive to compress the first spring 335. The compressed first spring 335 can exert a driving force on the first sliding disc 334 to always move downward. After the thickness of the first grinding disc 31 is reduced, the elastic force of the first spring 335 can make the first sliding disc 334 move downward in the slide sleeve 332, thereby making up for the gap distance between the first grinding disc 31 and the upper surface of the rail, thereby ensuring the rust removal quality of the upper surface of the rail.

[0034] Furthermore, the cross section of the first sliding post 336 is polygonal, which can prevent the first sliding post 336 from deflecting in the slide sleeve 332 when rotating.

[0035] Furthermore, a plurality of vertical slide bars 3321 are provided on the inner wall of the slide sleeve 332, and a plurality of slide grooves 3341 slidably matched with the vertical slide bars 3321 are opened on the outer wall of the slide plate 334. The cooperation between the vertical slide bars 3321 and the slide grooves 3341 can also prevent the first slide column 336 from deflecting in the slide sleeve 332 when rotating.

[0036] The utility model adds a secondary rust removal device 4 for removing rust on both sides of the track, and the two second grinding discs 43 are moved downward by the second lifting mechanism 41. The second lifting mechanism 41 includes a second mounting plate 411, a second lifting electric push rod 412 and an adjusting motor 413. A mounting plate 414 is installed on the output end of the adjusting motor 413. The second mounting plate 411 is arranged in the mounting cavity 12. The second lifting electric push rod 412 is vertically arranged on the top of the second mounting plate 411. The adjusting motor 413 is vertically connected to the output end of the second lifting electric push rod 412. The first bidirectional electric push rod 42 is horizontally connected to the mounting plate 414.

[0037] The first bidirectional electric push rod 42 and the two second grinding discs 43 are driven downward by the second lifting electric push rod 412, and the adjusting motor 413 can drive the first bidirectional electric push rod 42 to rotate, so that the first bidirectional electric push rod 42 and the two second grinding discs 43 can be hidden in the installation cavity 12. After the two second grinding discs 43 are respectively located on both sides of the track, the first bidirectional electric push rod 42 works to drive the two second grinding discs 43 to abut against the side walls on both sides of the track.

[0038] The second grinding disc 43 is always in contact with the side wall of the track through the second abutment mechanism 44, and the second abutment mechanism 44 includes a third connecting disc 441, on which at least two second slide posts 442 are slidably arranged, and a limiting plate 443 is provided at the tail end of the second slide post 442, and a second spring 444 is provided between the limiting plate 443 and the third connecting disc 441, and the second spring 444 is sleeved on the second slide post 442, and the second grinding disc 43 is detachably connected to the head end of all second slide posts 442.

[0039] The elastic force of the second spring 444 pulls the limit plate 443, and the limit plate 443 drives the second slide column 442 to move toward the side wall of the track. The second slide column 442 drives the second grinding disc 43 to always move toward the side wall of the track. Once the thickness of the second grinding disc 43 is reduced, the second grinding disc 43 can be driven by the elastic force of the second spring 444 to make up for the missing gap distance, thereby ensuring the quality of rust removal.

[0040] Furthermore, a plurality of third screws 431 are provided on the back of the second grinding disc 43, and a third nut 432 cooperating therewith is provided on the third screw 431, a connecting piece 445 is provided on the head end of the second sliding column 442, and a third through hole is provided on the third connecting disc 441 for the third screw 431 to pass through, so that the second grinding disc 43 can be easily disassembled and replaced.

[0041] Furthermore, the cross section of the second sliding post 442 is polygonal, which can prevent the second sliding post 442 from deflecting.

[0042] A dust suction pump body 14 is also provided on the top of the vehicle plate 1, and two first connecting ports 141 are provided on the dust suction pump body 14. A second bidirectional electric push rod 15 is horizontally arranged on the bottom of the vehicle plate 1 and located between the two connecting seats 11. Dust hoods 16 are provided on the two slides of the second bidirectional electric push rod 15, and the two dust hoods 16 are symmetrically arranged. A second connecting port 161 is provided at the tail end of the dust hood 16. The two second connecting ports 161 are respectively connected to the two first connecting ports 141 through pipes. The suction force can be transmitted to the two dust hoods 16 through the dust suction pump body 14. The dust generated during the rust removal process can be adsorbed by the dust hood 16, thereby improving environmental protection.
