Description

Technical Field

[0001] This invention relates to the technical field of short-distance movement of railway rail steel, and more specifically to a handling device for short-distance movement of railway rail steel. Background Technology

[0002] When rail steel is frequently moved short distances or its angle adjusted during processing and installation, and using lifting machinery is inconvenient or uneconomical, multiple people are usually required to carry it by hand or on their shoulders. This results in high labor intensity and low work efficiency for the workers. If the workers do not cooperate properly, it can easily lead to accidents where workers are struck by the rail steel. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a handling device for short-distance movement of railway rail steel.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a handling device for short-distance movement of rail steel, comprising two support frames, a lifting frame, a roller bearing frame, and a clamping structure. The two support frames are arranged opposite to each other, and an adjustment groove is provided through the inner side of each support frame. The lifting frame is vertically and vertically disposed within the adjustment groove. A telescopic groove is provided through the upper part of the opposite face of the lifting frame. The roller bearing frame is telescopically disposed within the telescopic groove. The rollers of the roller bearing frame support the inner top of the rail steel. A moving groove is provided through the lower front and rear of the lifting frame. The port and side of the moving groove are through-holes. The clamping structure is movably disposed within the moving groove and clamps the two inner sides of the rail steel.

[0005] In the above technical solution, the distance between the two support frames is adjusted, and they are respectively set on both sides of the rail steel. Multiple sets of support frames can be set for coordinated use. After the position is determined, the horizontal position is adjusted by the roller support frame to the inner sides of the rail steel. The height of the lifting frame is adjusted so that the rollers on the roller support frame abut against the top inner side of the rail steel. As the lifting frame rises, the rail steel is also raised along with the roller support frame, causing the rail steel to detach from the ground for short-distance movement. The moving clamping structure, which is movable within the moving slots at the front and rear of the lifting frame, clamps the inner sides of the rail steel. When moving in the same direction, the clamping structure in the opposite direction does not work, allowing for single-direction use. This enables the rail steel to be clamped and moved a short distance in one direction. The rollers provide auxiliary support and reduce friction during movement. When transporting the rail steel in different positions and directions, the clamping structure maintains the stability of the rail steel on the support frame. The position of the support frame is adjusted to allow for short-distance transport of the rail steel.

[0006] Based on the above technical solutions, preferably, the roller support frame includes a roller body and a frame body. The frame body is slidably disposed in the telescopic groove. A rotating opening is provided through one end of the frame body near the rail steel. The roller body is rotatably disposed in the rotating opening. The roller body protrudes from the port of the rotating opening.

[0007] Based on the above technical solutions, preferably, a first electric push rod is provided in the telescopic groove, and the output end of the first electric push rod is connected to the rear end of the frame.

[0008] In the above technical solution, the output end of the first electric push rod drives the frame to move out of the telescopic groove, so that the rollers on the frame move to the two inner sides of the rail steel, so that the rail steel can be lifted off the ground for short-distance transport.

[0009] Based on the above technical solution, preferably, the frame further includes a rotating frame, an adjusting motor, and a connecting block. An arc-shaped groove is provided through one end of the frame near the rail steel. The rotating frame is disposed within the arc-shaped groove, with its bottom sides rotatably connected to the inner wall of the arc-shaped groove. The rotating frame is through-type. A roller is rotatably connected within the rotating frame, and the roller protrudes relative to the top of the rotating frame. An arc-shaped opening is provided through the outside of the frame relative to the arc-shaped groove. The adjusting motor is nested outside the frame. The connecting block is disposed on the output end of the adjusting motor corresponding to the arc-shaped opening. The connecting block has an extension within the arc-shaped opening, and the extension is connected to the upper side of the rotating frame.

[0010] In the above technical solution, when the two inner sides of the rail steel are arc-shaped, in order to better support the rail steel, the angle of the roller body is adjusted to fit the inner side of the rail steel, so as to form better support for the rail steel. The output end of the adjusting motor drives the connecting block to change the angle along the arc-shaped opening, so that the top of the rotating frame changes the angle accordingly, thereby enabling the roller body to effectively fit the inner shape of the rail steel and effectively improve the stability of the support.

[0011] Based on the above technical solutions, preferably, the clamping structure includes a moving block, a clamping block, and a second electric push rod. The moving block is slidably disposed in the moving groove, and a pushing groove is provided through the side of the moving block near the rail steel. The second electric push rod is disposed in the pushing groove, and the clamping block is slidably disposed in the pushing groove. The output end of the second electric push rod is connected to the rear end of the clamping block, and the end of the clamping block abuts against the two inner sides of the rail steel.

[0012] Based on the above technical solutions, preferably, a push cylinder is provided at the rear end of the front and rear moving slots, and the output end of the push cylinder is connected to the moving block.

[0013] In the above technical solution, when the rail steel is short-distance connected, the clamping structure corresponding to a certain direction performs clamping operation, and the output end of the push cylinder drives the moving block to be used in a certain direction. The clamping structure and the push cylinder in the opposite direction do not work, so that the rail steel can be transported short distance along a certain direction. The output end of the second electric push rod drives the clamping block to clamp the rail steel.

[0014] Based on the above technical solutions, preferably, it also includes an extension structure, which is used for adjusting the distance between the two support frames. The extension structure includes an extension plate, wherein an extension groove is provided through the opposite surface of one of the support frames, the extension plate is slidably disposed in the extension groove, and one end of the extension plate is connected to the other support frame.

[0015] Based on the above technical solutions, preferably, the extension structure further includes a positioning rod, the extension plate is provided with a plurality of positioning holes, the extension groove is provided with positioning holes through the extension plate, and the positioning holes penetrate the top of the support frame, and the positioning rod is disposed in the positioning holes that coincide with the extension groove and the extension plate.

[0016] In the above technical solution, the distance between the two support frames is adjusted by adjusting the length of the extension plate to match the wider dimensions of the rail steel, so as to better adapt to short-distance handling operations.

[0017] Based on the above technical solution, preferably, a drive cylinder is provided around the bottom of the adjustment groove. The output end of the drive cylinder is connected to the bottom of the lifting frame. The height of the lifting frame is adjusted through the output end of the drive cylinder, thereby adjusting the height of the roller support frame so as to lift the rail steel off the ground for short-distance transport.

[0018] Based on the above technical solutions, preferably, both support frames are provided with casters around their bottom edges, and a number of casters are used for moving the support frames.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Adjust the distance between the two support frames and set them on both sides of the rail steel. Multiple sets of support frames can be set up for coordinated use. After the position is determined, the horizontal position is moved by the roller support frame and adjusted to the two inner sides of the rail steel. The height of the lifting frame is adjusted so that the rollers on the roller support frame abut against the top of the inner side of the rail steel. As the height of the lifting frame is raised, the rail steel is also raised along with the roller support frame, so that the rail steel is separated from the ground for short-distance movement, reducing manpower consumption, facilitating the carrying of the rail steel, and making it easy to move the rail steel short distances.

[0021] 2. The movable clamping structure in the front and rear moving slots of the lifting frame forms a clamping structure on both inner sides of the rail steel. When moving in the same direction, the clamping structure in the opposite direction does not work, and it is only used in one direction. This allows the rail steel to be clamped and moved a short distance in one direction. The roller body provides auxiliary support and reduces friction during movement. When it is necessary to transport the rail steel in different positions and directions, the clamping structure can maintain the stability of the rail steel on the support frame. By moving the position of the support frame, the rail steel can be transported a short distance. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1-4 As shown, the present invention discloses a handling device for short-distance movement of rail steel, comprising two support frames 1, a lifting frame 2, a roller bearing frame 3, and a clamping structure 4. The two support frames 1 are arranged opposite to each other. An adjustment groove 11 is provided through the inner side of the support frame 1. The lifting frame 2 is raised and lowered within the adjustment groove 11. A drive cylinder 12 is provided around the bottom of the adjustment groove 11. The output end of the drive cylinder 12 is connected to the bottom of the lifting frame 2, and the height of the lifting frame 2 is adjusted through the output end of the drive cylinder 12. A telescopic groove 21 is provided through the upper part of the opposite side of the lifting frame 2. The roller bearing frame 3 is telescopically arranged within the telescopic groove 21. The rollers of the roller bearing frame 3 support the inner top of the rail steel 5. A moving groove 22 is provided through the lower front and rear of the lifting frame 2. The port and side of the moving groove 22 are in a through state. The clamping structure 4 is movably arranged within the moving groove 22 and clamps the two inner sides of the rail steel 5. Universal wheels 13 are provided around the bottom of both support frames 1, and several universal wheels 13 are used for the movement of the support frames 1.

[0031] The distance between the two support frames 1 is adjusted, and they are positioned on both sides of the rail steel 5. Multiple sets of support frames 1 can be set up for coordinated use. After the positions are determined, the horizontal position is adjusted by the roller support frame 3 to the inner sides of the rail steel 5. The height of the lifting frame 2 is adjusted so that the rollers 31 on the roller support frame 3 abut against the top of the inner side of the rail steel 5. As the height of the lifting frame 2 rises, the rail steel 5 is also raised along with the roller support frame 3, allowing the rail steel 5 to detach from the ground for short-distance movement. The movable clamping structure 4 in the front and rear movable grooves 22 of the frame 2 forms a clamping on the two inner sides of the rail steel 5. When moving in the same direction, the clamping structure 4 in the opposite direction does not work and is only used in one direction, so that the rail steel 5 can be clamped and moved a short distance in one direction. The roller body 31 provides auxiliary support and reduces movement friction. When it is necessary to transport the rail steel 5 in different positions and directions, the clamping structure 4 can maintain the stability of the rail steel 5 on the support frame 1. The rail steel 5 can be transported a short distance by moving the position of the support frame 1.

[0032] In a preferred embodiment, the roller support frame 3 includes a roller body 31 and a frame 32. The frame 32 is slidably disposed in the telescopic groove 21. A rotating opening 33 is provided through one end of the frame 32 near the rail steel 5. The roller body 31 is rotatably disposed in the rotating opening 33, with the roller body 31 protruding from the port of the rotating opening 33. A first electric push rod 23 is provided in the telescopic groove 21. The output end of the first electric push rod 23 is connected to the rear end of the frame 32. The output end of the first electric push rod 23 drives the frame 32 to move out of the telescopic groove 21, so that the roller body 31 at the frame 32 moves to the two inner sides of the rail steel 5, so that the rail steel 5 can be lifted off the ground for short-distance transport.

[0033] In a preferred embodiment, the clamping structure 4 includes a movable block 41, a clamping block 42, and a second electric push rod 43. The movable block 41 is slidably disposed within the movable groove 22. A pushing groove 44 is provided through the movable block 41 near the side of the rail steel 5. The second electric push rod 43 is disposed within the pushing groove 44. The clamping block 42 is slidably disposed within the pushing groove 44. The output end of the second electric push rod 43 is connected to the rear end of the clamping block 42. The end of the clamping block 42 abuts against the two inner sides of the rail steel 5. Each rear end of the unit is equipped with a push cylinder 24. The output end of the push cylinder 24 is connected to the moving block 41. When the rail steel 5 is short-distance connected, the clamping structure 4 in a certain direction performs a clamping operation, and the moving block 41 is driven by the output end of the push cylinder 24 in a certain direction. The clamping structure 4 and the push cylinder 24 in the opposite direction do not work, so that the rail steel 5 can be transported short distance along a certain direction. The output end of the second electric push rod 43 drives the clamping block 42 to clamp the rail steel 5.

[0034] In a preferred embodiment, an extension structure 6 is also included. The extension structure 6 is used for adjusting the distance between the two support frames 1. The extension structure 6 includes an extension plate 61, wherein an extension groove 14 is provided through the opposite surface of one support frame 1, and the extension plate 61 is slidably disposed in the extension groove 14. One end of the extension plate 61 is connected to the other support frame 1. The extension structure 6 also includes a positioning rod 62. The extension plate 61 is provided with a plurality of positioning holes 63. The extension groove 14 is provided with positioning holes 63 through the extension plate 61, and the positioning holes 63 penetrate the top of the support frame 1. The positioning rod 62 is disposed in the positioning holes 63 that coincide with the extension groove 14 and the extension plate 61. By adjusting the length of the extension plate 61, the distance between the two support frames 1 can be adjusted to fit the wider dimensions of the rail steel 5, so as to better adapt to short-distance handling operations.

[0035] like Figure 5-6As shown, in another preferred embodiment, the frame 32 includes a rotating frame 325, an adjusting motor 323, and a connecting block 322. An arc-shaped groove 326 is provided through one end of the frame 32 near the rail steel 5. The rotating frame 325 is disposed within the arc-shaped groove 326, with its bottom sides rotatably connected to the inner wall of the arc-shaped groove 326. The rotating frame 325 is through-hole shaped. A roller body 31 is rotatably connected within the rotating frame 325, and the roller body 31 protrudes relative to the top of the rotating frame 325. An arc-shaped opening 324 is provided through the outer side of the frame 32 relative to the arc-shaped groove 326. The adjusting motor 323 is nested outside the frame 32. The connecting block 322 corresponds to the arc-shaped groove 326. An arc-shaped opening 324 is located on the output end of the adjusting motor 323. The connecting block 322 has an extension 321 inside the arc-shaped opening 324. The extension 321 is connected to the upper side of the rotating frame 325. When the two inner sides of the rail steel 5 are arc-shaped, in order to better support the rail steel 5, the angle of the roller body 31 is adjusted to fit the inner side of the rail steel 5, so as to form better support for the rail steel 5. By adjusting the output end of the motor 323, the connecting block 322 is driven to change angle along the arc-shaped opening 324, so that the top of the rotating frame 325 changes angle accordingly, thereby enabling the roller body 31 to effectively fit the inner shape of the rail steel 5, effectively improving the stability of the support.
