Description

Technical Field

[0001] The invention belongs to the field of the middle groove of a scraper conveyor, and in particular relates to a C-shaped groove assembly tool. Background Art

[0002] At present, the structural form of the middle trough in China is mainly a cast-welded structure, which is mainly composed of baffle groove side, shovel plate groove side, middle plate, bottom plate, and rack socket assembly. Since the coal, gangue, etc. mined by the coal mining machine all fall on the middle trough, they are directly in contact with the middle plate, and then run in the middle trough with the moving scraper. Therefore, the friction force on the middle plate is very large, and it is constantly circulating, and the wear of the middle plate will be very serious. The middle plate has only one layer and cannot be replaced. After the middle plate is worn, it can only be repaired by surfacing. There are many middle troughs and the area of ​​the middle plate is large. The surface quality of the surfacing repair is poor, and it will cause the middle trough to deform and twist, and the strength is reduced. In order to improve the strength of the middle trough, patent 20152084469614 discloses a high-strength composite C-type trough structure, which is mainly composed of a C-type trough, a groove side assembly and a rack seat assembly, wherein the C-type trough includes an upper middle plate and a groove side edge arranged at both ends above the upper middle plate. The C-shaped groove is assembled on the assembly platform, and the assembly process is as follows: 1. Draw a right-angle line on the platform; 2. Align the end face and outer side face of one groove side along the line respectively; 3. Spot weld the groove side on the platform; 4. Place another groove side parallel to the first groove side, with the chain path opening facing each other and the end faces aligned; 5. Adjust the second groove side and measure the groove width to make it correct; 6. Spot weld the groove side on the platform; 7. Cover the upper middle plate on the groove side, adjust the marked end to align, and overlap both sides evenly; 8. Position weld the upper middle plate and the groove side; 9. Lap weld the tie rods at both ends of the C-shaped groove close to the platform; 10. Cut off the spot welds of the groove side and the platform with fire, and smooth the cut marks; 11. Turn it over, and position weld the upper middle plate and the inner side of the groove side. The disadvantages of the existing C-shaped groove assembly method are: before assembling each C-shaped groove, the groove edge alignment line is drawn on the assembly platform, and the groove edge must be spot welded on the assembly platform during the assembly process. After assembling the C-shaped groove, the groove edge is cut off from the assembly platform by fire, and then the assembly platform is polished flat. This assembly method is inefficient; second, the groove edge must be spot welded on the assembly platform and then cut off by fire, which will damage the assembly platform; third, there are differences in personal measurement, resulting in large errors in the size of the C-shaped groove.

[0023] like Figure 1-7As shown, a C-shaped groove assembly tool comprises a frame 1, and the frame 1 comprises a positioning plane for positioning the upper surface of two groove side edges 80 of the C-shaped groove 8. The frame 1 is provided with four length positioning blocks 3, and the four length positioning blocks 3 are respectively located near the four corners of a rectangle, and the long side of the rectangle corresponds to the outer side line of the upper surface of the two groove side edges 80 of the C-shaped groove 8 in the length direction; each length positioning block 3 comprises a length positioning surface 30, and the length positioning surfaces 30 of two adjacent length positioning blocks 3 in the length direction of the rectangle are arranged opposite to each other and the shortest distance between the two length positioning surfaces 30 corresponds to the length of the groove side edge 80; the length positioning surfaces of two adjacent length positioning blocks 3 in the width direction of the rectangle are on the same plane. The length positioning block 3 is provided with an inner width positioning plate 4 for limiting the inward movement of the groove side edge 80, and the inner width positioning plate 4 is provided with an inner stop width positioning surface 40 in contact with the inner surface of the groove side edge 80. The minimum distance between two adjacent inner width positioning surfaces 40 in the width direction of the rectangle corresponds to the minimum distance between the inner surfaces of the two groove side edges 80 of the C-shaped groove 8 at the corresponding height; at least one outer width positioning plate 5 for limiting the outward movement of the groove side edge 80 is respectively arranged on the outer sides of the two long sides of the rectangle. The upper surface of the groove side edge 80 of the C-shaped groove 8 refers to the outer surface of the end of the groove side edge 80 away from the middle plate 81; the inner surface of the groove side edge 80 is the surface pointing to the inside of the C-shaped groove 8, and the outer side surface of the groove side edge 80 refers to the surface away from the inside of the C-shaped groove 8. The inner width of the groove side edge 80 refers to the distance between the inner surfaces of the two groove side edges 80 of the C-shaped groove 8. Because the inner surface of the groove side edge 80 is not a plane, the inner width is different at different heights. The length positioning surfaces 30 of the four length positioning blocks 3 are used to position the length direction of the two groove side edges 80 and limit their movement; the inner width positioning plate 4 and the outer width positioning plate 5 are used to position the width direction of the two groove side edges 80 and limit their movement. The limiting structure is simple and can be repeated. The length positioning block 3 and the outer width positioning plate 5 can be set on the frame by welding or bolting. The C-shaped groove 8 is positioned by the assembly tool, and there is no need to draw the alignment line, which reduces the assembly time and improves the assembly efficiency; the assembly does not require measurement, and the assembly size accuracy is higher. It is fixed by the assembly tool, and spot welding is not required, which protects the assembly platform.

[0024] The inner width positioning plate 4 is rotatably arranged on the length positioning block 3, a positioning boss 32 is arranged on the length positioning block 3, and a detachable pressing positioning block is also arranged on the length positioning block 3; when the inner width positioning plate 4 is rotated to contact with the positioning boss 32, it cannot be rotated any further, and the pressing positioning block presses the inner width positioning plate 4 from the direction opposite to the positioning boss 32. That is, when the inner width band positioning plate 4 is rotated to contact with the positioning boss 32, the pressing positioning block and the positioning boss 32 are respectively located on both sides of the inner width positioning plate 4. The inner width positioning plate 4 is rotatably arranged on the upper surface of the length positioning block 3 through a first pin shaft, and a pin hole corresponding to the first pin shaft is arranged on the length positioning block 3. The positioning boss 32 can be a rectangular block set on the upper surface of the length positioning block 3, and a boss positioning surface 33 is set on the positioning boss 32. A rectangular notch corresponding to the positioning boss 32 can also be set on the inner width positioning plate 4. The side of the rectangular notch is a notch positioning surface 41 that contacts and positions the boss positioning surface 33. When the notch positioning surface 41 is pressed against the boss positioning surface 33, the inner width positioning surface 40 on the inner width positioning plate 4 is located at a standard position. The inner width positioning surface 40 can be the same plane as the notch positioning surface 41, or a different plane, as long as the accurate positioning function can be met.

[0025] The clamping positioning block is a wedge cap pin 7, the lower part of the wedge cap pin 7 is a pin shaft, and the upper part is a head end wedge block or an inverted cone; a pin hole corresponding to the pin shaft part of the wedge cap pin 7 is arranged on the length positioning block 3; the wedge cap pin 7 moves downward, and the head wedge block or the inverted cone presses the inner width positioning plate 4. The installation and removal of the wedge cap pin 7 are very convenient, and the clamping effect is also very good. Of course, the press positioning block can also be a cam, and the camshaft of the cam is rotated in the shaft hole corresponding to the camshaft on the length positioning block, and the rotation of the cam can press the inner width positioning plate 4.

[0026] The inner width positioning plate 4 has two states, one is the open state, take out the wedge cap pin 7, turn the inner width positioning plate 4 to Figure 5 The groove edge 80 can be taken out or placed at this time. After the groove edge 80 is placed, the inner width positioning plate 4 is rotated to Figure 6 In the middle position, the boss positioning surface 33 of the positioning boss 32 of the length positioning block 3 cooperates with the notch positioning surface 41 of the inner width positioning plate 4 for positioning, and then the wedge cap pin 7 is inserted to limit the position, and the inner width positioning plate 4 is used to limit the inner width of the groove side edge 80.

[0027] The surface of the outer width positioning plate 5 facing the long side of the rectangle is spaced a certain distance from the long side of the rectangle, and a width limiting wedge block 6 is arranged between the outer width positioning plate 5 and the groove side edge 80; the width of the upper end of the width limiting wedge block 6 is greater than the width of the lower end, and the width limiting wedge block 6 is moved downward to limit the groove side edge 80 from the outside of the groove side edge 80.

[0028] The outer width positioning plate 5 is provided with a slide groove 50 on one side facing the long side of the rectangle; the width limiting wedge 6 slides in the slide groove 50. The width limiting wedge 6 can be an inverted right-angled trapezoid, with one vertical waist sliding in the slide groove 50 and the other inclined waist pressing against the outer surface of the groove side 80 to limit the position. The slide groove 50 structure can prevent the width limiting wedge 6 from shifting during the movement process.

[0029] The inner width positioning plate 4 is detachably arranged on the length positioning block 3. The inner width positioning plate 4 can be fixed to the length positioning block 3 by bolts or other fixing methods. After the groove side edge 80 is placed between the length positioning blocks 3, the inner width positioning plate 4 is fixed to the length positioning block 3.

[0030] Two pads 2 whose length directions are not perpendicular or overlapped with each other are arranged on the frame 1, and the upper surfaces of the two pads 2 constitute a positioning plane. The positioning plane can be the upper surface of the frame 1. During the assembly process, the positioning surface requires a certain degree of precision, such as surface roughness and flatness, to ensure the assembly precision and the size of the C-shaped groove after assembly. If the entire upper surface of the frame 1 is processed to the same precision, the processing cost will increase. Therefore, two pads 2 are arranged on the frame 1, and the upper surfaces of the two pads 2 constitute the positioning plane of the upper surface of the groove side edge 80. During processing, it is only necessary to process the upper surface of the pad 2 to the required precision, and the surface that needs to be processed is reduced, which can effectively reduce the processing cost. Preferably, the two pads 2 are arranged in parallel, and the length direction of the pad 2 is perpendicular to the length direction of the groove side edge 80; the pad 2 is in the shape of a long strip.

[0031] Specific implementation process: C-slot assembly tooling assembly process:

[0032] (1) During assembly, place the groove edge 80 on the base plate 2 of the frame 1 in the center and perpendicular to the base plate 2.

[0033] (2) Adjust the length positioning block 3 and the outer width positioning plate 5 to the appropriate position according to the height and width of the groove side edge 80, and fix the length limiting block 3 and the outer width positioning plate 5 to the frame 1 by welding or bolting. The outer width positioning plate 5 is kept at a certain distance from the groove side edge 80 for the later wedging of the width limiting wedge block 6.

[0034] (3) The two end surfaces of the groove side along the length direction of 80 degrees are respectively close to the length positioning blocks 3 at both ends to complete the length direction positioning. At this time, the inner width positioning plate 4 on the length positioning block 3 is always in an open state.

[0035] (4) The inner width positioning plate 4 is rotated and closed to be in a closed state, and the wedge cap pin 7 is inserted to fix the inner width positioning plate 4.

[0036] (5) Make the inner stop surface of the groove side 80 close to the inner width positioning plate 4, and wedge the width limiting wedge 6 downward between the groove side 80 and the outer width positioning plate 5 to complete the positioning of the groove side 80 in the width direction.

[0037] (6) After the groove edge 80 is fixed as a whole, the middle plate 81 is placed on the groove edge 80 and adjusted so that the middle plate 80 and the groove edge end surfaces are aligned and overlapped evenly on both sides. Then, the middle plate 81 and the groove edge 80 are tack welded.

[0038] (7) After the positioning welding is completed, the tie bars are welded under the groove edge 80 near the two ends, and the C-shaped groove 8 is welded.

[0039] (8) Take out the width limiting wedge block 6 and the wedge cap pin 7, rotate the inner width positioning plate 4 to open it, and take out the C-shaped groove 8.

[0040] The C-shaped groove of the present invention is assembled by an assembly tool, and there is no need to repeatedly mark the alignment line and fix it with spot welding, thereby improving the assembly efficiency; welding and fire cutting are no longer required when the C-shaped groove is fixed and removed, thereby protecting the assembly platform; the assembly positioning size of the C-shaped groove is determined by the assembly tool, and no longer needs to be determined by manual measurement, thereby reducing assembly errors.
