Referring to fig. 1 to 3, the lifting tool for tube sheets of the embodiment of the present invention is used for lifting a tube sheet 100, and includes a first clamping groove 200 and a second clamping groove 300, the first clamping groove 200 and the second clamping groove 300 are made of steel plates with a thickness of 10 to 20mm, a first opening 210 for embedding the tube sheet 100 is disposed on the front side of the first clamping groove 200, and a second opening 310 for embedding the tube sheet 100 is disposed on the front side of the second clamping groove 300. The segment 100 is simultaneously inserted into the first and second holding grooves 200 and 300 during handling. The cross-sectional shapes of the first clamping groove 200 and the second clamping groove 300 are both C-shaped. The right side of the upper end of the first clamping groove 200 is hinged to the left side of the upper end of the second clamping groove 300, the two lifting lugs 400 are symmetrically arranged at the upper ends of the first clamping groove 200 and the second clamping groove 300, the lifting lugs 400 are used for being connected with hoisting equipment such as an electric hoist and the like, and the first clamping groove 200 and the second clamping groove 300 can rotate relatively to clamp the duct piece 100 under the action of gravity during lifting. The clamping force of the first clamping groove 200 and the second clamping groove 300 on the tube sheet 100 is related to the self weight of the tube sheet 100 and the position of the lifting lug 400. The larger the self weight of the segment 100 is, the larger the clamping force is, and the farther the lug 400 is from the hinge of the first clamping groove 200 and the second clamping groove 300 is, the larger the clamping force is.
According to the special lifting appliance for the duct pieces, the first clamping groove 200 is connected with the second clamping groove 300 in a hinged mode, the lifting lugs 400 on the first clamping groove 200 and the second clamping groove 300 are subjected to tension force during lifting, so that the first clamping groove 200 and the second clamping groove 300 rotate relatively until the duct pieces 100 are clamped, when the duct pieces 100 with different diameters are lifted, the duct pieces 100 with different diameters can be conveniently embedded into the first clamping groove 200 and the second clamping groove 300 by adjusting the positions of the first clamping groove 200 and the second clamping groove 300, the special lifting appliance can adapt to the duct pieces 100 with different diameters, clamps do not need to be replaced when the duct pieces 100 with different diameters are lifted in lifting operation, the working efficiency is improved, and the clamp cost is saved.
In some embodiments of the present invention, the first roller 220 is connected to the lower end of the first clamping groove 200, and the second roller 320 is connected to the lower end of the second clamping groove 300. The first roller 220 and the second roller 320 can contact with the ground to support the clamp during transportation, so that the clamp is convenient for an operator to move.
In some embodiments of the present invention, a first telescopic rod 230 is disposed between the first roller 220 and the first clamping groove 200 to adjust the height of the first clamping groove 200, a second telescopic rod 330 is disposed between the second roller 320 and the second clamping groove 300 to adjust the height of the second clamping groove 300, since the segments 100 are horizontally placed on the ground, the heights of the tops of the segments 100 with different diameters from the ground are not consistent, the height of the first opening 210 can be adjusted to match the segment 100 by adjusting the first telescopic rod 230, and the height of the second opening 310 can be adjusted to match the segment 100 by adjusting the second telescopic rod 330. So as to push the first clamping groove 200 and the second clamping groove 300 to insert the segment 100 into the first clamping groove 200 and the second clamping groove 300.
In some embodiments of the present invention, an elastic rope 500 is disposed between the first telescopic rod 230 and the second telescopic rod 330, two ends of the elastic rope 500 are directly tied to the first telescopic rod 230 and the second telescopic rod 330, the elastic rope 500 drives the first telescopic rod 230 and the second telescopic rod 330 to approach each other, so that the first clamping groove 200 and the second clamping groove 300 can be maintained at a certain angle when the segment 100 is not hoisted by the first clamping groove 200 and the second clamping groove 300, and when the first clamping groove 200 and the second clamping groove 300 slide on the ground through the first roller 220 and the second roller 320, the elastic rope 500 maintains an included angle between the first clamping groove 200 and the second clamping groove 300. When the segment 100 is lifted by the first clamping groove 200 and the second clamping groove 300, the tensile force acting on the lifting lug 400 can overcome the elastic force of the elastic rope 500, so that the first clamping groove 200 and the second clamping groove 300 rotate relatively to clamp the segment 100. In the process of putting the segment 100 down, the pulling force acting on the lifting lug 400 is reduced, and the first holding groove 200 and the second holding groove 300 are automatically rotated by the elastic cord, thereby releasing the fixation of the segment 100.
In some embodiments of the present invention, the handles 700 are disposed at the rear sides of the first clamping groove 200 and the second clamping groove 300 to facilitate grasping by a worker, and since the first clamping groove 200 and the second clamping groove 300 need to be manually moved when the first clamping groove 200 and the second clamping groove 300 are placed on the ground, the arrangement of the handles 700 can effectively improve the working efficiency.
In some embodiments of the present invention, the first clamping groove 200 and the second clamping groove 300 are both arc-shaped, so that the segment 100 is more stably limited in the first clamping groove 200 and the second clamping groove 300. The contact area between the duct piece 100 and the first clamping groove 200 and the second clamping groove 300 is larger during hoisting, so that the duct piece 100 can be prevented from being damaged during hoisting.
In some embodiments of the present invention, rubber pads are disposed at the lower ends of the inner sides of the first clamping groove 200 and the second clamping groove 300, and the rubber pads can be directly adhered to the rubber pads in the first clamping groove 200 and the second clamping groove 300 by glue, so as to increase friction force and prevent the duct piece 100 from slipping off during hoisting, and the rubber pads also play a role in buffering and preventing damage to the duct piece 100.
In some embodiments of the present invention, the reinforcing ribs 600 are disposed outside the first clamping groove 200 and the second clamping groove 300, and since the first clamping groove 200 and the second clamping groove 300 are thinner and may be deformed when the duct piece 100 with a larger size is hoisted, the reinforcing ribs 600 are welded to the first clamping groove 200 and the second clamping groove 300, and the reinforcing ribs 600 are steel sections such as channel steel and angle steel.
The method comprises the following steps: connecting the lifting lugs 400 on the first clamping groove 200 and the second clamping groove 300 with a hoisting device, adjusting the heights of the first telescopic rod 230 and the second telescopic rod 330 to enable the duct piece 100 to be aligned with the first opening 210 and the second opening 310, pushing the rear end of the duct piece 100 to be abutted against the side wall in the first clamping groove 200 or the second clamping groove 300 by an operator through the first clamping groove 200 and the second clamping groove 300, and starting the hoisting device to hoist the first clamping groove 200 and the second clamping groove 300. Under the action of gravity, the first clamping groove 200 and the second clamping groove 300 rotate relatively to clamp the segment 100. After hoisting equipment lifts the duct piece 100 to a discharging point, the duct piece 100 is put down, the first clamping groove 200 and the second clamping groove 300 rotate oppositely and relatively under the action of the elastic rope after the duct piece 100 is put down, the fixing of the duct piece 100 is removed, and then an operator pushes away the first clamping groove 200 and the second clamping groove 300.
