Description

Technical Field

[0001] The utility model relates to a nailing device, in particular to a nailing device for wooden sleeper rail rows. Background Art

[0002] Track laying projects in underground mines usually involve nailing the rails on the surface in advance. Especially in inclined shaft track laying projects, construction workers face many difficulties due to the complex construction conditions in the inclined shaft. After nailing the pads on the rails on the surface according to the position of the rails, they are transported to the underground construction site for installation, which can effectively improve construction efficiency.

[0003] At present, the nailing work of the pads mainly relies on manual hammering, which not only consumes a lot of manpower, but also has a high safety risk during the operation.

[0004] In addition, the technical level of the nailing workers also directly affects the quality of the rails. During the nailing process, the distance between the rails and the distance between the sleepers must be accurately placed according to the pre-set requirements. However, the preset positions may change, especially the distance between the rails, which requires the construction workers to continuously measure and adjust during the nailing process to ensure that the specified size standards are met. This process is not only time-consuming and labor-intensive, but once the size deviation occurs due to negligence, it will directly affect the installation progress on site and increase the difficulty of construction.

[0029] Figure 3 for Figure 1 Magnified view of part B. DETAILED DESCRIPTION

[0030] The technical solution of the utility model is described in detail below with reference to the accompanying drawings:

[0031] like Figures 1 to 3 A nailing device suitable for a wooden sleeper rail row includes a base 1, a longitudinal guide rail 2 arranged on the base 1, a longitudinal moving part 3 moving forward and backward along the longitudinal guide rail 2, and a transverse moving part 4 moving left and right along the longitudinal moving part 3, and a jack 5 for pressing the spikes is provided at the bottom of the transverse moving part 4.

[0032] Specifically, the base 1 includes a bottom plate 1-2 and a plurality of longitudinally arranged support beams 1-1 welded to the bottom of the bottom plate 1-2. The support beams 1-1 should be fixed to the ground anchor or the existing building as a whole and cannot be moved.

[0033] The longitudinal guide rails 2 are divided into two groups, left and right, using I-beams and directly fixed on the bottom plate 1-2.

[0034] The longitudinal moving part 3 includes a transverse guide rail beam 3-3, two groups of columns 3-2 whose upper ends are fixedly connected to both ends of the transverse guide rail beam 3-3, and a first guide wheel 3-1 installed at the lower end of the column 3-2; the first guide wheel 3-1 cooperates with the longitudinal guide rail 2 on the corresponding side.

[0035] Furthermore, ribs 8 are fixed along the entire length of both sides of the longitudinal guide rail 2, and limit hook plates 3-4 are installed on both sides of the column 3-2. The horizontal part of the bottom of the limit hook plate 3-4 is located below the ribs 8 to prevent the longitudinal moving part 3 from tipping over.

[0036] The transverse moving part 4 moves left and right along the transverse guide beam 3-3 of the longitudinal moving part 3, and includes a U-shaped connecting plate 4-1 and a second guide wheel 4-2 installed on two side plates of the connecting plate 4-1 and matched with the transverse guide beam 3-3.

[0037] The jack 5 is installed at the bottom of the connecting plate 4 - 1 .

[0038] Furthermore, two groups of vertical plates 4-5 are provided at the bottom of the connecting plate 4-1. Vertical guide grooves are provided on the vertical plates 4-5, and pin shafts 4-4 that can move up and down are installed in the guide grooves.

[0039] The spring 4-3 for pulling the pin 4-4 upwards is also installed on the vertical plate 4-5. When the pin 4-4 moves to the lower limit position, the elongation of the spring 4-3 must not exceed the limit stretching length.

[0040] The lateral moving part 4 also includes an L-shaped plate fork 4-6, the upper end of the vertical part of the plate fork 4-6 is connected to the pin shaft 4-4, and the horizontal part of the lower end is provided with a fork opening for placing a spike.

[0041] A convex shaft 10 is also installed at the lower end of the jack 5. The convex shaft 10 is provided with an outer arc surface, which cooperates with the inner arc surface at the corner of the plate fork 4-6 and is used to push open the plate fork 4-6 when the plate fork 4-6 moves downward to the extreme position.

[0042] The base 1 is also provided with a rail limiter 6 and a sleeper limiter 7. The rail limiter 6 is a plurality of sets of channel steels welded on the bottom plate 1-2, which limit the position of the rails from both sides. The sleeper limiter 7 is a plurality of sets of angle steels welded on the bottom plate 1-2, and each four sets of angle steels correspond to a row of sleepers, respectively wrapping the four right-angle sides of the sleepers.

[0043] When nailing, first place the wooden sleeper in the wooden sleeper limiter 7, then place the rail in the rail limiter 6, then lift the rail, place pads 9 at both ends of each wooden sleeper, and then put down the rail. The rail presses the pads 9, and the protrusions on the pads 9 are aligned with the sides of the rail. Then move the longitudinal moving part 3 and the transverse moving part 4 so that the jack 5 is located above the pads 9 to be nailed, place the spikes on the fork of the plate fork 4-6, and then control the jack 5 to drive the spikes into the nail holes on the pads 9. When nailing, at the beginning, the spikes drive the plate fork 4-6 and the pin 4-4 to move downward synchronously. At this time, the plate fork 4-6 plays a certain guiding role to ensure that the spikes are vertically nailed into the wooden sleeper for a distance. When the pin 4-4 moves to the lower end of the guide groove, the plate fork 4-6 cannot continue to descend, and the convex shaft 10 will push the plate fork 4-6 open. The plate fork 4-6 rotates around the pin 4-4, separates from the spike, and moves upward under the action of the spring 4-3. Thereafter, the jack 5 continues to drive the spike into the wooden sleeper until the spike is in close contact with the pad 9.
