[0001] The invention relates to the technical field of coal mill striking plates, in particular to a welding device. Background Art

[0002] The main reasons for the breakage of the squirrel cage bars of the coal mill motor are heavy load and frequent start-up, so it is necessary to set up a strike plate to protect the squirrel cage bars of the coal mill motor. The manufacturing process of the coal mill strike plate is mostly casting and welding. Compared with the welding process, casting requires molding, pouring, cleaning, and harsh environment. In addition, the cast strike plate has poor toughness and is prone to crack defects inside.

[0035] Example 1

[0036] Reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a welding device, including a construction assembly 100, including a construction member 101 and a striking plate member 102;

[0037] The clamping assembly 200 includes a clamping member 201 disposed on one side of the structural member 101, an adjusting member 202 disposed on one side of the structural member 101, a locking member 203 disposed on one side of the structural member 101, and an unlocking member 204 disposed on one side of the locking member 203;

[0038] The clamping member 201 includes a mounting block 201 a disposed on one side of the structural member 101 , and a clamping block 201 c slidably disposed on one side of the mounting block 201 a . The clamping block 201 c is in close contact with the striking plate 102 .

[0039] Specifically, the structural member 101 includes a base plate 101a, a support rod 101b arranged on one side of the base plate 101a, an adjustment plate 101c slidably arranged on the outside of the support rod 101b, and a workbench 101d arranged on one side of the support rod 101b, and the striking plate member 102 includes a striking plate body 102a arranged on one side of the structural member 101.

[0040] Furthermore, the clamping member 201 includes a mounting block 201a disposed on one side of the workbench 101d, an adjustment slot 201b provided on one side of the mounting block 201a, a clamping block 201c slidably disposed on one side of the adjustment slot 201b, the side of the clamping block 201c contacting the adjustment slot 201b is configured as an arc block so that it can slide along the direction of the adjustment slot 201b, a first patch 201d disposed on one side of the clamping block 201c and a second patch 201e disposed on one side of the clamping block 201c, when welding, the first patch 201d is closely attached to the upper surface of the striking plate body 102a The second sticking block 201e is tightly attached to the side wall of the striking plate body 102a to clamp and fix the striking plate body 102a. The clamping member 201 includes an adjusting rod 201f slidably set on one side of the adjusting plate 101c and a through slot 201g opened on both sides of the clamping block 201c. One end of the adjusting rod 201f extends into the clamping block 201c and is slidably set therewith. The clamping member 201 also includes a limit block 201h set on both sides of the adjusting rod 201f, one end of the limit block 201h extends into the through slot 201g, and the limit block 201h is used to limit the clamping block 201c.

[0041] Furthermore, the adjusting member 202 includes an inner cavity 202a opened on one side of the mounting block 201a, and an adjusting bolt 202b threadedly arranged on one side of the mounting block 201a. The adjusting bolt 202b is rotated to slide inward and outward to adjust the space size inside the inner cavity 202a, thereby limiting the sliding distance of the rebound block 202c and the rebound column 202d. The rebound block 202c slidably arranged on one side of the inner cavity 202a, the rebound column 202d arranged on one side of the rebound block 202c, and the tension spring 202e sleeved on one side of the rebound column 202d are tensioned. The two ends of the force spring 202e are respectively connected to the side wall of the rebound column 202d and the side wall of the inner cavity 202a, and the rebound block 202c and the rebound column 202d are reset at the same time. The adjustment member 202 also includes a stop column 202f arranged on one side of the clamping block 201c and a hook block 202g arranged on one side of the rebound block 202c. The hook block 202g is arranged on the outside of the stop column 202f. The hook block 202g is used to limit the stop column 202f, thereby reducing the possibility of the stop column 202f and the clamping block 201c falling off when sliding in the adjustment groove 201b.

[0042] Operation process: Before welding, place the strike plate to be welded on the workbench 101d, pull the adjustment plate 101c downward, the adjustment plate 101c slides to drive the adjustment rod 201f to slide, thereby driving the clamping block 201c to slide obliquely downward along the direction of the adjustment groove 201b, so that the first block 201d is close to the upper surface of the strike plate body 102a, and the second block 201e is close to the side wall of the strike plate body 102a, and then fixed by the locking piece 203, so as to realize the synchronous drive clamping of the four clamping blocks 201c, and quickly clamp and fix the four corners of the strike plate, and then start welding.

[0043] When welding is completed and the striking plate body 102a needs to be taken out, the unlocking piece 204 is used to unlock the striking plate body 102a. After unlocking, the adjusting rod 201f slides upward again. During the sliding process, the adjusting rod 201f is affected by the restoring force of the tension spring 202e, driving the rebound column 202d and the rebound block 202c to reset and slide, thereby driving the blocking column 202f and the clamping block 201c to slide obliquely upward along the direction of the adjusting groove 201b, so that the clamping block 201c strikes the plate body 102a in principle, releasing the clamping thereof, and at the same time, by rotating the adjusting bolt 202b to slide inward and outward, the size of the space inside the inner cavity 202a is adjusted, thereby limiting the sliding distance of the rebound block 202c and the rebound column 202d. During the sliding process, the hook block 202g is used to limit the blocking column 202f, thereby reducing the possibility of the blocking column 202f and the clamping block 201c falling off when sliding in the adjusting groove 201b.

[0044] Example 2

[0045] Reference Figure 2-Figure 7, which is the second embodiment of the present invention. It is different from the previous embodiment in that: the locking member 203 includes a sliding block 203a arranged on the outside of the adjusting column, and a locking block 203b arranged on one side of the sliding block 203a. The locking member 203 also includes a rotating shaft 203c rotatably arranged on one side of the workbench 101d, and a locking box 203d arranged on one side of the rotating shaft 203c. When the locking box 203d rotates, it can drive the rotating shaft 203c to rotate, a pressure plate 203e slidably arranged in the locking box 203d, and a wedge block 203f arranged on one side of the pressure plate 203e. The inclined portion of the wedge block 203f contacts the inclined portion of the locking block 203b.

[0046] Specifically, the locking member 203 also includes a limit rod 203g arranged in the locking box 203d and a compression spring 203h arranged in the locking box 203d. The two ends of the compression spring 203h are respectively connected to the side wall of the pressure plate 203e and the inner wall of the locking box 203d. The compression spring 203h is used to reset the pressure plate 203e, thereby resetting the wedge block 203f. When the sliding block 203a slides downward, the inclined portion of the locking block 203b contacts the inclined portion of the wedge block 203f, squeezing the wedge block 203f inward so that it and the pressure plate 203e slide toward the direction of the locking box. When the sliding block 203a needs to be pulled upward, the horizontal portion of the locking block 203b contacts the horizontal portion of the wedge block 203f, and the sliding block 203a is locked and locked to each other, thereby fixing the adjusting rod 201f and the clamping block 201c.

[0047] Furthermore, the unlocking member 204 includes a support frame 204a arranged on one side of the adjustment plate 101c, a toothed plate 204b slidably arranged on the upper side of the support frame 204a, a sliding groove is opened on the upper side of the support frame 204a, and the toothed plate 204b slides in the sliding groove without the possibility of falling off. At the same time, the length of the toothed plate 204b is greater than the length of the support frame 204a, a toothed disc 204c arranged on one side of the locking box 203d and a rotating rod 204d arranged on one side of the toothed disc 204c, the toothed disc 204c and the toothed plate 204b are meshed, and the rotating rod 204d is fixedly arranged on one side of the toothed plate 204b, and the rotating rod 204d rotates to drive the toothed disc 204c to rotate, and the toothed disc 204c rotates to drive the toothed plate 204b to slide, and the toothed plate 204b will always be meshed with the toothed disc 204c and will not fall off.

[0048] Preferably, the unlocking member 204 also includes a return spring 204e sleeved on the outside of the adjusting rod 201f, and the two ends of the return spring 204e are respectively connected to the side wall of the sliding block 203a and the side wall of the workbench 101d, and the return spring 204e is used to reset and drive the sliding block 203a, and a torsion spring 204f sleeved on the outside of the rotating shaft 203c, and the torsion spring 204f is used to reset and rotate the rotating shaft 203c and the locking box after unlocking, and is used for the next locking and fixing, and the two ends of the return spring 204e are respectively connected to the side wall of the workbench 101d and the side wall of the sliding block 203a.

[0049] The rest of the structure is the same as that of Example 1.

[0050] Operation process: When the sliding block 203a slides downward, the inclined portion of the locking block 203b contacts the inclined portion of the wedge block 203f, squeezing the wedge block 203f inward, causing it and the pressure plate 203e to slide toward the inside of the locking box. When the sliding block 203a needs to be pulled upward, the horizontal portion of the locking block 203b contacts the horizontal portion of the wedge block 203f, locking the sliding block 203a together, thereby fixing the adjusting rod 201f and the clamping block 201c, and clamping and fixing the striking plate body 102a.

[0051] When the adjusting plate 101c slides downward to the end position, the tooth plate 204b just meshes with the tooth disc 204c. When unlocking is required, the rotating rod 204d is rotated to drive the tooth disc 204c to rotate, and the rotation of the tooth disc 204c drives the tooth plate 204b to slide. During the sliding process of the tooth plate 204b, the inner tooth disc 204c is driven to rotate synchronously. When the tooth disc 204c rotates, it drives the locking box 203d to rotate, so that the wedge block 203f and the locking block 203b are separated from each other, so that the sliding The movable block 203a and the adjusting rod 201f can be slid up and down for adjustment, thereby releasing the stuck fixation of the locking block 203b, and simultaneously releasing the clamping fixation of the four clamping blocks 201c on the striking plate body 102a. At the same time, during the upward sliding process, the tooth plate 204b is separated from the tooth disc 204c again, releasing the locking fixation of the tooth disc 204c. At this time, the locking box 203d is subjected to the restoring force of the torsion spring 204f, driving the locking box to reset and rotate for the next locking fixation.

[0052] Example 3

[0053] Reference Figure 8-Figure 9 , which is the third embodiment of the present invention, and is different from the above embodiments in that this embodiment provides a coal mill striking plate, including the above welding device, and also includes a wear-resistant assembly 300, including a wear-resistant member 301 arranged on one side of the striking plate body 102a and a ventilation member 302 arranged on one side of the striking plate body 102a;

[0054] The wear-resistant member 301 includes a surfacing wear-resistant layer 301 a disposed on one side of the striking plate body 102 a , and the ventilation member 302 includes a ventilation opening 302 a opened on one side of the striking plate body 102 a .

[0055] Specifically, the ventilation area of ​​the striking wheel is increased by providing the ventilation opening 302a.

[0056] The rest of the structure is the same as that of Example 2.

[0057] Operation process: The fan coal mill impact wheel, the original design of the impact plate thickness is 110mm for the outer impact plate and 130mm for the inner impact plate, which is cast by the casting production process. The impact plate thickness is now transformed into 80mm for the outer impact plate and 100mm for the inner impact plate through welding. The base material is a wear-resistant cladding layer, which is manufactured by welding process. The comparison before and after the improvement is as follows:

[0058] The original design weight of a set of striking plates was 3750kg. After the thickness changed, the weight of a set of striking plates was 2849.88kg, and the weight of a set of striking plates was reduced by 900.12kg. The weight reduction changed the starting inertia of the striking wheel when starting and stopping, reduced the starting current, protected the squirrel cage bars of the coal mill motor, and thus reduced energy consumption and saved costs. After the design structure size changed, each vent 302a of the striking wheel was enlarged, which increased the ventilation area of ​​the striking wheel. The manufacturing process was changed from casting to welding, and the service hours of the striking plates increased from 800 hours to 2000 hours.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
