Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-2, a roadbed construction tamping device comprises a frame 1 and a mounting plate 2 fixedly connected with the frame 1, the mounting plate 2 is fixed on the surface of the frame 1, a motor 3 is arranged on one side of the mounting plate 2, the motor 3 is fixedly connected with the mounting plate 2, the motor 3 is used for providing driving force for tamping a roadbed, an output shaft of the motor 3 penetrates through the mounting plate 2, a turntable 4 is fixedly connected with a free end of the output shaft of the motor 3, a track 6 is arranged on one side of the turntable 4, the track 6 is slidably connected with the frame 1 through a slide bar, an ejector rod 5 matched with the track 6 is arranged on one side of the turntable 4, the ejector rod 5 is eccentrically arranged relative to the turntable 4, the ejector rod 5 is fixedly connected with the turntable 4, the ejector rod 5 is in contact with an inner ring of the track 6, the ejector rod 5, the track 6 moves up and down in the frame 1 along with the ram 5.

The scheme has the following working processes:

when needing to tamp the roadbed, pushing equipment to the roadbed that needs tamp, motor 3 starts, and motor 3 drives carousel 4 and rotates, and carousel 4 and then drive eccentric ejector pin 5 and rotate, and eccentric ejector pin 5 acts on the inner wall of track 6 always, and track 6 is along with ejector pin 5 up-and-down motion, and the slide bar of track 6 bottom drives the vertical up-and-down motion of tamping plate under the limiting displacement of sleeve and frame 1, and stable tamps the roadbed.

According to the working process, the following steps are known:

the motor 3 drives the rotary table 4 to rotate, the rotary table 4 further drives the eccentric ejector rod 5 to rotate, the eccentric ejector rod 5 acts on the inner wall of the track 6 all the time, the track 6 moves up and down along with the ejector rod 5, the slide rod at the bottom of the track 6 drives the tamping plate to vertically move up and down under the limiting action of the sleeve and the frame 1, compared with the prior art, when the soil is tamped, the rack is driven by the gear to tamp up and down, when the tamping plate acts on the ground, the ground simultaneously generates opposite vibration force, the opposite vibration force on the ground is transmitted to the positions of the rack and the teeth of the gear, so that the abrasion of the teeth is easily aggravated, the service life of the soil tamping machine is shortened, the turntable 4 is used for driving the ejector rod 5 to slide on the inner wall of the track 6 to push the track 6 to move up and down, the ground is tamped, the abrasion between the mandril 5 and the track 6 is small, and the service life of the soil tamping machine is long.

Further, the ejector rod 5 is rotatably connected with the rotary table 4, when the ejector rod 5 ejects the track 6, the ejector rod 5 and the track 6 rotate relatively, when the rotary table 4 rotates, the ejector rod 5 drives the track 6 to move up and down, the ejector rod 5 rotates relative to the track 6, sliding friction between the ejector rod 5 and the track 6 is converted into rotating friction of the ejector rod 5, abrasion between the track 6 and the ejector rod 5 is reduced, and the service lives of the track 6 and the ejector rod 5 are prolonged.

Furthermore, the surface of the ejector rod 5 is carved with anti-skidding lines, when the ejector rod 5 rotates relative to the track 6, the anti-skidding lines on the surface of the ejector rod 5 increase the static friction force between the anti-skidding lines and the inner wall of the track 6, so that the ejector rod 5 can rotate conveniently, and further the abrasion between the ejector rod 5 and the track 6 is reduced.

Furthermore, the outer side of the ejector rod 5 is provided with a baffle 9 used for limiting the track 6, the baffle 9 is fixedly connected with the ejector rod 5, when the ejector rod 5 moves in the inner ring of the track 6, the baffle 9 blocks the side surface of the track 6, the side surface of the track 6 is limited, and the stable movement of the track 6 is facilitated.

Further, track 6 includes depressed part 7, and when ejector pin 5 removed to depressed part 7, track 6 was upwards ejecting, and depressed part 7 can promote track 6 ejecting height that makes progress, and then promotes the lifting distance of ramming plate, and the gravity work increase of ramming plate promotes the ramming effect of ramming plate to the road bed, makes things convenient for track 6's use more.

Further, track 6 still includes bulge 8, before ejector pin 5 moves to bulge 8, ejector pin 5 breaks away from with bulge 8, when ejector pin 5 rotates down along with carousel 4, track 6 breaks away from ejector pin 5, and track 6 is because the action of gravity, and track 6 descends because the action of gravity along with the ramming plate, tamps ground, and ground can not act on between guide rail and the ejector pin 5 to the counter-vibration force of ramming plate, reduces ejector pin 5 and track 6 because the wearing and tearing of ground counter-vibration force.

Further, 6 both sides of bulge 8 on track all are equipped with balancing weight 10, and every balancing weight 10 all with 6 fixed connection on track, when 6 downstream on track, balancing weight 10 promotes the tamping effect of tamping plate, makes things convenient for more to tamp the road bed.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
