[0023] Figure 1 and Figure 2 An embodiment of a leveling tool of a shore bridge bending plate 1 of the present application is shown. As shown in Figure 1 and Figure 2 The shore bridge bending plate 1 described in the present application has a bending surface, and the bending plate 1 needs to be placed on a workshop rack for welding operation.
[0024] The leveling fixture of this utility model includes a support structure 100, a leveling structure 200, and fasteners 300. The leveling structure 200 includes a support plate 210 and an adjusting member 220 connected to the support plate 210. The support plate 210 is located above the adjusting member 220 and is used to support the quay crane bending plate 1. The support plate 210 is flat and can be tightly fitted to the bending surface of the bending plate 1, whether the bending surface of the bending plate 1 is facing upwards or downwards, to lift the bending plate 1 and provide stable force support.
[0025] The adjusting member 220 is provided with a rotating part 221 and a slotted part 222 communicating with the rotating part 221. The support structure 100 is provided with a rotating mating part 101. The rotating mating part 101 can mate with both the rotating part 221 and the slotted part 222.
[0026] like Figure 1 As shown, when the leveling fixture is in the first state, that is, when the rotating mating part 101 and the slotted part 222 are engaged, the adjusting part 220 is in a horizontal state, and the support plate 210 is used to support the quay crane bending plate 1 with the bending surface facing down.
[0027] like Figure 2 As shown, when the leveling fixture is in the second state, and the rotating mating part 101 and the rotating part 221 are engaged, the adjusting member 220 can rotate relative to the supporting structure 100, thereby causing the adjusting member 220 to be inclined relative to the supporting structure 100. The supporting plate 210 is used to support the quay crane bending plate 1 with the bending surface facing upward. The inclination angle between the adjusting member 220 and the supporting structure 100 can be adjusted according to the actual situation to ensure that it is in close contact with the bending plate 1.
[0028] like Figure 3 As shown, the fastener 300 is assembled on the rotating mating part 101 to fix the position of the adjusting member 220 so that the leveling fixture can be kept in the first state or the second state.
[0029] The leveling fixture of the quay crane bending plate 1 of this utility model cooperates with the grooving part 222 and the rotating part 221 respectively through the rotating mating part 101. The tilt angle of the leveling fixture can be adjusted according to the bending direction of the bending plate 1, thereby lifting and adjusting each bending plate 1 to ensure that the adjacent butt joint edges of the bending position of the bending plate 1 are close to the horizontal state so that the welding trolley can work normally.
[0030] Compared to the existing self-made process supports in the workshop, the leveling fixture of this utility model can adapt to the actual angle changes of the bending plate 1, has a higher adaptability to the actual angle changes of the bending plate 1, is safer to use on site, and facilitates smooth operation of workshop production.
[0031] According to the statistics of the bending angle of the bending surface of the multiple quay crane projects, the bending angle of the bending surface is generally 161 degrees. The leveling tool can be completely adapted to the bending angle.
[0032] In an embodiment, the rotating matching part 101 is a protruding part (hereinafter, the reference sign 101 represents the protruding part), and the rotating part 221 is a sliding rail 221 (hereinafter, the reference sign 221 represents the sliding rail 221) matched with the protruding part 101. At least part of the protruding part 101 is located in the sliding rail 221. The sliding rail 221 can slide along the protruding part 101 under the guidance of the protruding part 101, and the sliding rail 221 can rotate relative to the protruding part 101, so that the adjustment flexibility of the adjusting part 220 is greater, and the adaptability to the bending plate 1 is better.
[0033] In another embodiment, the rotating matching part 101 is a sliding rail 221, and the rotating part 221 is a protruding part 101 matched with the sliding rail 221, which can also realize the sliding and rotating actions of the adjusting part 220.
[0034] The leveling tool includes opposite first and second sides 10 and 20. When the adjusting part 220 is inclined relative to the support structure 100, that is, when the leveling tool is in the second state, as shown in Figure 2 , the first side 10 is lower than the second side 20. The sliding rail 221 is arranged close to the second side 20 relative to the first side 10. The sliding rail 221 can be Figure 1 and Figure 2 shown as a long waist-shaped hole having a first end and a second end. Among them, the first end of the sliding rail 221 is close to the first side 10, and the second end is close to the second side 20. When the bending surface of the bending plate 1 faces upward, the protruding part 101 and the second end of the sliding rail 221 abut, which can effectively increase the contact area of the support plate 210 and the bending plate 1. And make the leveling tool as much as possible on the outside of the plate unit, so as to facilitate the safe disassembly of the construction personnel.
[0035] The support structure 100 includes a base and a support part 120 arranged on the base. The support part 120 is provided with a through hole 121 matched with the protruding part 101, and the protruding part 101 passes through the through hole 121 and the sliding rail 221, so that the adjusting part 220 can move relative to the support part 120.
[0036] The base includes a base 111 and a support rod 112 arranged on the base 111. The support rod 112 and the base 111, and the support rod 112 and the support part 120 are welded and connected, which can stably support the entire leveling tool and vertically transmit the force to the ground. The base 111 can be circular, so that the center of gravity is within the diameter range of the base 111, facilitating the entire leveling tool to stand alone in the non-use state, and facilitating the use of the tool.
[0037] The height of the support rod 112 can be designed according to the height of the bent plate 1 from the ground (the height of the plate bending + the height of the tire stand 2). In order to reduce the manufacturing and maintenance costs, and the use environment is a fixed place, the length of the support rod 112 is not adjustable.
[0038] Further, the through hole 121 is arranged close to the circumferential edge of the support 120 relative to the center of the support 120, and close to the second side 20 relative to the first side 10 of the leveling tool. That is, the through hole 121 is arranged eccentrically, so that the center of gravity of the leveling tool is as close to the center position as possible, preventing the leveling tool from overturning, so as to improve the stability of the leveling tool.
[0039] The adjusting part 220 includes oppositely arranged first adjusting plate 220-1 and second adjusting plate 220-2, and both the first adjusting plate 220-1 and the second adjusting plate 220-2 are provided with sliding rails 221. Figure 3 As shown, the support plate 210 is welded above the first adjusting plate 220-1 and the second adjusting plate 220-2. The support 120 includes oppositely arranged first clamping plate 120-1 and second clamping plate 120-2. The first clamping plate 120-1 and the second clamping plate 120-2 are connected by a bottom plate 120-3. Both the first clamping plate 120-1 and the second clamping plate 120-2 are provided with through holes 121. The first adjusting plate 220-1 and the second adjusting plate 220-2 can be inserted into the space formed by the first clamping plate 120-1 and the second clamping plate 120-2, so that the first adjusting plate 220-1 and the first clamping plate 120-1 are opposite, the second adjusting plate 220-2 and the second clamping plate 120-2 are opposite, and the sliding rails 221 and the through holes 121 are opposite.
[0040] Optionally, the protruding part 101 is a bolt (hereinafter the reference numeral 101 represents the bolt), and the fastener 300 is a nut (hereinafter the reference numeral 300 represents the nut). The shank of the bolt 101 can pass through the first clamping plate 120-1, the first adjusting plate 220-1, the second adjusting plate 220-2 and the second clamping plate 120-2 in sequence, and the nut 300 locks the shank extending from the second clamping plate 120-2.
[0041] On the basis of the above-mentioned embodiments, the slotted part 222 is a semicircular groove matched with the bolt 101, and located above the sliding rail 221. As shown, Figure 1 When the bending surface is downward, the bolt 101 falls into the semicircular groove, which can eliminate the angle deviation of the bent plate 1 due to the unequal length of the two sides, facilitate the complete adhesion of the contact surface, and prevent sliding, and the force is stable and balanced.
[0042] The leveling tool further comprises a limiting baffle 400. The limiting baffle 400 is arranged on the supporting piece 120 and is located at the second side 20 of the leveling tool, i.e. close to the second end of the slide rail 221. The limiting baffle 400 is connected with the first adjusting plate 220-1 and the second adjusting plate 220-2. In combination with the through hole 121 arranged eccentrically on the supporting piece 120, when the bending surface faces upward, the limiting baffle 400 can control the rotating direction of the adjusting piece 220 in one direction, i.e. the direction as shown in the figure, so that the on-site adjustment of the tool can be reduced. Figure 2 When the bending surface faces downward, the adjusting piece 220 and the limiting baffle 400 abut against each other to provide a supporting effect for the adjusting piece 220, so that the bolt 101 is prevented from being subjected to force alone, and the service life of the part is improved.
[0043] Optionally, the leveling tool is machined from a steel plate by machining.
[0044] In combination with the above embodiment, the on-site use process of the leveling tool is as follows:
[0045] Firstly, the crane firstly loads the bending plate 1 onto the workshop jig 2, the bending surface faces upward, and the crane does not release the hook. The leveling tool is inserted from the side, the bending plate 1 is placed at a close distance, and one side of the bending plate 1 is in a horizontal state. At this time, personnel cannot enter the bending projection area of the plate unit.
[0046] After the welding of the one side of the bending plate 1 is completed, when the bending surface faces downward, the leveling tool is adjusted according to the state, when the bending plate 1 is hung by the crane and one side has contacted the jig 2, the other side is placed below the bending plate 1, and the distance between the leveling tool and the joint of the bending plate 1 is estimated. At this time, personnel leave, and the bending plate 1 is lowered by the crane.
[0047] Finally, after the joint of the bending plate 1 is welded, the bending plate 1 is hung by the crane, the leveling tool is taken out, the welded side is placed on the jig 2, the other side is lifted, and the leveling assembly step is repeated.
[0048] The utility model discloses although the above-mentioned preferable embodiment is disclosed, but it is not used to limit the utility model, and any person skilled in the art can make possible change and modification without departing from the spirit and scope of the utility model. Therefore, any modification, equivalent change and modification made to the above-mentioned embodiment according to the technical essence of the utility model, all fall within the protection scope defined by the utility model claim.
