[0018] The following describes the invention of the present invention in detail by way of examples in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Example

[0019] like Figure 1As shown, the utility model discloses an assembly structure of a vehicle-mounted drilling and workover rig mast and Y bracket, comprising a main vehicle 1, a rear bracket 2, a mast 4 and a Y bracket 6 are provided at the rear end of the main vehicle 1, the rear bracket 2, the mast 4 and the Y bracket 6 are connected by a hinge seat 3 and fixed with a pin, and the mast 4 is rotatably connected to the hinge seat 3; the side of the mast 4 close to the rear bracket 2 is connected to the Y bracket 6 by a pressure plate group 8, and the side of the mast 4 away from the rear bracket 2 is connected to the Y bracket 6 by a guide pressure plate group 7, and the guide pressure plate group 7 is locked by a connecting seat 5; when the mast 4 is lifted to the operating state, the mast 4 rests on the Y bracket 6, with the guide pressure plate group 7 and the pressure plate group 8 in contact in the middle and locked by the connecting seat 5; when the drilling and workover rig is transported, it is only necessary to release the lock of the connecting seat 5, lower the mast 4 onto the main vehicle 1, and the Y bracket 6 can be transported without disassembly.

[0020] like Figure 2 As shown, the pressure plate group 8 includes a derrick pressure plate 81 and a Y-bracket pressure plate 82 . The derrick pressure plate 81 is welded to the derrick 4 , and the Y-bracket pressure plate 82 is welded to the Y-bracket 6 .

[0021] like Figure 3 As shown, the guide pressure plate group 7 includes a derrick guide pressure plate 71 and a Y-bracket guide pressure plate 72. The derrick guide pressure plate 71 is welded to the derrick 4, and the Y-bracket guide pressure plate 72 is welded to the Y-bracket 6. A positioning pin 73 is provided on the derrick guide pressure plate 71, and a positioning groove 74 is provided on the Y-bracket guide pressure plate 72. During assembly, the positioning pin 73 cooperates with the positioning groove 74.

[0022] like Figure 4 As shown, the connecting seat 5 includes a single-ear plate 51 and a double-ear plate 52. The single-ear plate 51 is welded to the derrick 4, and the double-ear plate 52 is welded to the Y bracket 6. The single-ear plate 51 and the double-ear plate 52 are connected by a pin.

[0023] like Figure 5 As shown, when assembling the derrick 4 and the Y bracket 6, place the derrick 4 on the supporting fixture, adjust the flatness of the derrick 4, and mark the center line of the derrick frame and the center line of the Y bracket 6. First, assemble the pressure plate group 8, then assemble the guide pressure plate group 7, and finally assemble the connecting seat 5. The specific assembly process is as follows:

[0024] (1) Assembling the pressure plate group 8: first spot-weld the derrick pressure plate 81 and the Y-bracket pressure plate 82 into position, then spot-weld the Y-bracket pressure plate 82 and the Y-bracket 6 in the pressure plate group 8 into position, then hoist the rear end of the Y-bracket 6 until the center line of the Y-bracket 6 coincides with the center line of the derrick frame, and spot-weld the derrick pressure plate 81 and the derrick 4 according to the contact position of the Y-bracket 6 and the derrick 4 at this time; then grind off the weld between the derrick pressure plate 81 and the Y-bracket pressure plate 82 to separate the derrick pressure plate 81 and the Y-bracket pressure plate 82, and finally weld the derrick pressure plate 81 and the Y-bracket pressure plate 82 to the derrick 4 and the Y-bracket 6 respectively.

[0025] After welding is completed, the edges of the pressure plate shrink toward the back due to welding deformation, and the center surface of the pressure plate is raised. The raised surface of the pressure plate needs to be ground. First, use red bile powder to determine the raised position of the pressure plate surface, and then use a grinder or other tools to grind it. During the grinding process, it is necessary to use red bile powder to check at any time to ensure that the raised parts of the surface are ground away. The contact area of ​​the two pressure plates is greater than 70%, and the gap between the non-contact parts is less than 0.5mm. After grinding is completed, the connection angle between the derrick 4 and the Y bracket 6 is determined.

[0026] (2) Assembling the guide pressure plate group 7: first spot-weld the derrick guide pressure plate 71 and the Y bracket guide pressure plate 72 to position them, then spot-weld the Y bracket guide pressure plate 72 and the Y bracket 6 in the guide pressure plate group 7 to position them, then hoist the rear end of the Y bracket 6 until the center line of the Y bracket 6 coincides with the center line of the derrick frame, and spot-weld the derrick guide pressure plate 71 and the derrick 4 according to the contact position of the Y bracket 6 and the derrick 4 at this time; then grind off the weld between the derrick guide pressure plate 71 and the Y bracket guide pressure plate 72 to separate the derrick guide pressure plate 71 and the Y bracket guide pressure plate 72, and finally weld the derrick guide pressure plate 71 and the Y bracket guide pressure plate 72 to the derrick 4 and the Y bracket 6 respectively.

[0027] After welding is completed, the guide pressure plate assembly 7 is ground according to the grinding method described in (1) above.

[0028] (III) Assembling the connecting base 5: First, position-weld the single-ear plate 51 on the derrick 4. Then, hoist the rear end of the Y-bracket 6 so that it is in close contact with the derrick 4. Attach the double-ear plate 52 to the Y-bracket 6. During assembly, use a pin to connect the single-ear plate 51 and the double-ear plate 52.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and application concept of the present invention, should be covered by the protection scope of the present invention.
