Summary of the invention

[0004] The object of the present invention is to overcome the deficiencies in the above-mentioned prior art and to provide a method for designing a deck-flush cab track chair. The method of the present invention is to sink and drill holes in the deck where the cab track chair is arranged, and install the slide rail embedded parts and the slide rail base at the lower end of the deck, so that the slide rail base is flush with the cab deck. The safety of the crew walking in the cab is guaranteed without affecting the installation and use of the track chair, and the aesthetics of the slide rail base installation location is improved.

[0005] In order to achieve the above invention purpose, the technical solution provided by the present invention is as follows:

[0006] A design method for a deck-flush cab track chair, the method specifically comprising the following steps:

[0007] The first step is to perform sinking drilling at the deck location where the cab rail chair is installed. After the sinking drilling is completed, a sinking deck surface is arranged within the opening surface, and the sinking deck surface is connected to the bottom of the deck through reinforcing rib plates around it;

[0008] The second step is to install the embedded parts of the slide rails in the middle of the sinking deck surface after the layout of the sinking deck surface is completed, and then install the slide rail base on the embedded parts of the slide rails. After the installation of the slide rail base is completed, position and open holes on the slide rail base;

[0009] Step 3: After the positioning hole of the slide rail base is completed, screw the fixing bolts into the positioning hole to fix the slide rail embedded parts and the slide rail base;

The sunken deck surface is below the opening of the cab deck, and the sunken deck surface is connected and fixed to the lower end of the cab deck by reinforcing rib plates around it. The reinforcing rib plates seal and connect the sinking deck surface around it, and the sunken deck surface is larger than the opening area of ​​the cab.

[0013] The above-mentioned slide rail embedded parts include slides and connecting parts. There are two slides in total, which are connected by connecting parts. The slides are vertically connected to the connecting parts. The two slides are arranged in parallel. The thickness of the slide rail embedded parts is 20mm-30mm. The length of the slide rail is less than the length of the deck opening. The width of the slide rail embedded parts is less than the width of the deck opening; the width of the slide rail embedded parts is 35mm larger than the width of the slide rail base.

[0030] In the second step, after the arrangement of the sunken deck surface 2 is completed, the slide rail embedded part 1 is installed in the middle of the sunken deck surface 2, and then the slide rail base 3 is installed on the slide rail embedded part 1. After the installation of the slide rail base 3 is completed, a positioning hole 31 is made on the slide rail base 3;

[0031] In the third step, after the positioning opening 31 of the slide rail base 3 is completed, the fixing bolt 4 is screwed into the positioning opening 31 to fix the slide rail embedded part 1 and the slide rail base 3;

[0032] Step 4: After the slide rail embedded parts 1 and the slide rail base 3 are fixed, the deck covering 5 is laid on the cab deck 7. After the deck covering 5 is laid, the decorative covers 6 are installed on both sides of the sunken deck surface 2;

[0033] Step 5: After the decoration cover 6 is installed, the track seat 8 is installed on the slide rail base 3 to complete the installation of the cab track seat 8.

[0034] The shape of the hole punched in the sinking in the first step is a rectangular hole, and the cab deck 7 is provided with rounded corners 21 around the hole, and the radius of the rounded corner 21 is 50 mm. The sunken deck surface 2 is below the opening of the cab deck 7, and the sunken deck surface 2 is connected and fixed to the lower end of the cab deck 7 by reinforcing ribs 22 around it. The reinforcing ribs 22 seal and connect the sunken deck surface 2 around it, and the sunken deck surface 2 is larger than the opening area of ​​the cab; the rounded corners 21 at the four corners of the hole of the cab deck 7 reduce the structural stress at the opening of the deck 7 and avoid deformation of the opening of the deck 7.

[0035] The above-mentioned slide rail embedded part 1 includes a slide 11 and a connecting part 12. There are two slides 11, which are connected by a connecting part 12. The slide 11 is vertically connected to the connecting part 12, and the two slides 11 are arranged in parallel. The thickness of the slide rail embedded part 1 is 20mm-30mm.

[0036] The above-mentioned slide rail embedded part 1 is installed in the middle part of the sunken deck surface 2, and the slideway 11 in the slide rail embedded part 1 is welded and fixed to the sunken deck surface 2. The opening length of the cab deck 7 is 35mm larger than the length of the slide rail embedded part 1, and the opening width of the cab deck 7 is 35mm larger than the width of the slide rail embedded part 1.

[0037] The specific steps of making the positioning holes 31 on the slide rail base 3 in the above-mentioned second step are: after the slide rail base 3 is installed on the slide rail embedded part 1, the positioning holes 31 are made at the four corners of the slide rail base 3 and on both sides of the middle part of the slide rail base 3, the depth of the positioning holes 31 is greater than the depth of the slide rail base 3, and the depth of the hole is less than the sum of the depth of the slide rail base 3 and the depth of the slide rail embedded part 1. After the positioning holes 31 on the slide rail base 3 are completed, the fixing bolts 4 are screwed into the positioning holes 31, and the fixing bolts 4 do not penetrate the thickness of the slide rail embedded part 1; the bottom of the fixing bolts 4 does not pass through the thickness of the slide rail embedded part, which not only defines the slide rail embedded part and the slide rail base, but also avoids damage to the sinking deck surface by the fixing bolts 4.

[0038] The above-mentioned slide rail base 3 is in a rectangular parallelepiped shape as a whole, and a long strip-shaped boss is arranged on the side surface of the slide rail base 3.

[0039] The thickness of the deck covering 5 laid in the fourth step is 12 mm. After the deck covering 5 is laid, the upper end surface of the slide rail base 3 is flush with the deck covering 5, and the height of the sunken deck surface 2 from the lower end of the driving deck 7 is the height of the slide rail embedded part 1 + the height of the slide rail base 3 - the thickness of the cab deck 7 - the thickness of the deck covering 5; by sinking and drilling at the deck 7 where the cab track chair 8 is arranged, the slide rail embedded part 1 and the slide rail base 3 are installed at the lower end of the deck 7, so that the slide rail base 3 is flush with the cab deck 7, which ensures the safety of the crew walking in the cab without affecting the installation and use of the track chair 8, and improves the aesthetics of the installation of the slide rail base 3.

[0040] The decorative cover 6 is L-shaped as a whole, one end of the decorative cover 6 is fixedly connected to the end face of the deck dressing 5, the other end of the decorative cover 6 is connected to the sunken deck surface 2, the outer end face of the decorative cover 6 is connected to the side of the slide rail embedded part 1, and the decorative cover 6 has the same length as the opening of the cab deck 7; by arranging the decorative cover 6 on both sides of the sunken deck surface 2, the grooves on both sides of the sunken deck surface 2 are closed, which improves the aesthetics of the track under the cab track seat 8 and prevents debris from entering the sunken deck surface 2.

[0041] The specific steps for installing the above-mentioned track chair 8 on the slide rail base 3 are: install the sliding plate 81 at the lower end of the track chair 8 on the slide rail base 3, and the side of the sliding plate 81 is stuck under the boss on the side of the slide rail base 3, and the side of the sliding plate 81 does not exceed the width range of the slide rail embedded part 1.
