Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0029] Please see Figs. 1-3 This utility model provides a technical solution: a lifting structure for a coke oven side protection iron component track site crane, including a site track, the site track being composed of several rail beams 1 and a lower base plate 2, the several rail beams 1 being placed on the upper side of the lower base plate 2, a lower cover plate 3 being installed on the inner side of the rail beams 1 and located on the lower base plate 2, an upper cover plate 4 being provided on the lower cover plate 3, a pair of lifting structures being provided between the lower cover plate 3 and the upper cover plate 4, and slope structures being provided between the upper cover plate 4 and the lower cover plate 3 at both the front and rear ends.

[0030] Example 1: The lifting structure includes an outer web plate 5 and an inner web plate 6. The outer web plate 5 is placed on the lower side of the upper cover plate 4, and the inner web plate 6 is disposed on the inner side of the outer web plate 5. The inner web plate 6 is connected to the lower cover plate 3. Both the inner web plate 6 and the outer web plate 5 are provided with a plurality of height adjustment holes 7 arranged in a rectangular array. High-strength adjusting bolts 8 are inserted between the height adjustment holes 7 on the inner web plate 6 and the height adjustment holes 7 on the outer web plate 5, which are in corresponding positions.

[0031] Specifically, during the installation of ironwork equipment for the coke oven side lining, due to the width of the site and the height difference of the track, the inside of the quenching car track needs to be filled with backfill soil, up to the height of the track surface. The backfill width should be 2m wider than the outside of the track, with a total width of 8 meters. The backfill length depends on the number of coke oven holes; for example, the backfill length for a 70-hole coke oven is about 140m. Based on these figures, the backfill volume is enormous. Furthermore, after the equipment is installed, all the backfill soil needs to be removed, which is difficult and costly, and the work itself is not efficient, resulting in significant cost waste. This patent eliminates the need for backfilling this area, allowing the crane to stand, transport vehicles to pass normally, and the lifting device to be moved easily and flexibly.

[0032] The I-beams are modified into T-beams, with two T-beam cover plates joined together. Multiple rows of holes are drilled in the web of the T-beams. Another set of these items is made to serve as the base. High-strength bolts are used as adjusting connectors. The multiple rows of holes in the web are high-strength bolt height adjustment sockets, used to adjust the height of the lower base and the upper support platform. Ramps are set on both sides for the truck crane to pass through. The size of the platform is adjusted according to the vehicle model, and the platform height is adjusted using adjustment holes and adjusting bolts.

[0033] Example 2: The slope structure includes a lower slope plate 9, which is connected to the lower cover plate 3. An upper slope plate 10 is installed on the lower slope plate 9, which is connected to the upper cover plate 4. A slope reinforcement plate 11 is provided between the lower slope plate 9 and the upper slope plate 10. The upper slope plate 10, the lower slope plate 9, and the slope reinforcement plate 11 are arranged in a triangular or A-shape.

[0034] Specifically, the position of the upper cover plate 4 is usually adjusted first, and then the corresponding length of the ramp plate 10 is selected and fixed between the ramp plate 9 and the upper cover plate 4 by welding or hooking.

[0035] Cylindrical plates 12 are installed on both the left and right sides of the lower plate 9 of the ramp. The cylinder 12 has an internal thread and a screw 13 is screwed inside the cylinder 12. A pad 14 is installed at the lower end of the screw 13. A pulley 16 is installed on the outer ring surface of the cylinder 12 and the pulley 16 is connected to the lower plate 9 of the ramp.

[0036] Specifically, this structure is for assisting the device to move back and forth. When no movement is needed, simply unscrew the pad 14.

[0037] Example 3: Anti-slip pads 15 are embedded on both the front and rear sides of the top of the upper cover plate 4, and anti-slip patterns are formed on the anti-slip pads 15;

[0038] Specifically, after the furnace protector is pushed up, wedge-shaped pads are inserted on both sides of the bottom of the furnace protector to prevent it from shifting, while the anti-slip pad 15 ensures that the pads do not shift.

[0039] A lifting method for a crane lifting structure of iron components in a coke oven side lining track area includes the following steps:

[0040] 1) Install a lifting structure next to rail beam 1 according to the wheel track of the crane;

[0041] 2) A new lifting structure is provided on the front side of the lower substrate 2, and the new lifting structure corresponds one-to-one with the lifting structure provided in step 1);

[0042] 3) Adjust the lifting structure set in step 1) so that its upper surface is flush with the upper surface of the rail beam 1;

[0043] 4) Adjust the lifting structure set in step 2) so that its upper surface is flush with the upper surface of the lower substrate 2;

[0044] 5) Fix the slope structure to the front of the lifting structure.

[0045] Step 5) includes:

[0046] The lifting structure is fixed to the front side of the slope structure by welding or hooks.

[0047] The length of the lower plate 9 of the slope structure located on the upper side is set as L, the degree of the upper plate 10 of the slope structure located on the lower side is set as L1, and the horizontal distance between the slope structure located on the upper side and the slope structure located on the lower side is set as L2. The value range of the length L is L2<=L<=L1+L2.

[0048] Where L = L1 + L2 is the optimal length;

[0049] The upper ramp 10 is set according to the height of the lifting structure and the length of the lower ramp 9, while ensuring that the angle between the upper ramp 10 and the lower ramp 10 is the same, thus completing the setup.
