DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-4 , Figure 1 This is a schematic diagram of the three-dimensional structure of a drilling elevator in a specific embodiment of the utility model; Figure 2 yes Figure 1 Schematic diagram of the enlarged structure at A in the middle; Figure 3 yes Figure 1 A side structural diagram of Figure 4 yes Figure 3 Schematic diagram of the enlarged structure at point B in the middle.

[0020] A drilling elevator for easy positioning includes a first fixing seat 1, a second fixing seat 2 is vertically rotatably mounted at the rear end edge of the first fixing seat 1, and a clamping mechanism is installed on the outer wall of the end of the first fixing seat 1 and the second fixing seat 2 away from each other.

[0021] The clamping mechanism includes a support plate 3, a rotating rod 4, a worm 5, and a hexagonal rotating head 6. The support plate 3 is fixedly installed on the outer wall of the end of the first fixed seat 1 and the second fixed seat 2 away from each other. The rotating rod 4 is longitudinally rotatably installed on each group of support plates 3. A worm 5 is fixedly installed at the middle position of each group of rotating rods 4. One end of each group of rotating rods 4 extends to the outside of the support plate 3 on the corresponding side, and is fixedly installed with a hexagonal rotating head 6.

[0022] The clamping mechanism also includes a sleeve 7, a worm gear 8, a threaded rod 9 and a splint 10. A sleeve 7 is rotatably installed on the outer wall of the first fixed seat 1 and the second fixed seat 2 on the side away from each other. A worm gear 8 is fixedly installed on the outer wall of each group of sleeves 7 at the corresponding position of the worm 5 on the corresponding side. Each group of worm gears 8 is threadedly connected to the worm 5 at the corresponding position. A threaded rod 9 is threadedly connected to the inside of each group of sleeves 7. The ends of the two groups of threaded rods 9 that are close to each other respectively pass through the inside of the first fixed seat 1 and the second fixed seat 2, and are fixedly installed with a splint 10. The two groups of splints 10 are both semicircular arc structures, and anti-slip pads 11 are fixedly installed on the outer wall of the end of the two groups of splints 10 that are close to each other.

[0023] Guide rods 12 are slidably installed on the outer walls of the first fixed seat 1 and the second fixed seat 2 that are away from each other. The ends of the two sets of guide rods 12 that are close to each other are fixedly connected to the splints 10 on the corresponding side, and hanging seats 13 are fixedly installed on the tops of the first fixed seat 1 and the second fixed seat 2.

[0024] When using this device, the pipe to be lifted is wrapped by rotating the first fixing seat 1 and the second fixing seat 2, and then the staff drives the rotating rod 4 to rotate by rotating the hexagonal rotating head 6, thereby driving the worm 5 to rotate. Because the worm 5 and the worm wheel 8 are meshingly connected, the worm wheel 8 is driven to rotate synchronously, and then the shaft sleeve 7 is driven to rotate. Because the internal thread of the shaft sleeve 7 is connected to the threaded rod 9, it can drive the splint 10 to move, so that the pipe can be clamped and fixed. The self-locking property of the worm wheel 8 and worm 5 provided in the clamping mechanism makes this device more stable when in use.

[0025] A fixed block 1401 is fixedly installed at the edge of the left outer wall of the first fixed seat 1, and a limiting plate 14 is rotatably installed at the left edge of the front end of the fixed block 1401. A first spring 15 is fixedly installed on the front outer wall of the fixed block 1401, and the other end of the first spring 15 is fixedly connected to the limiting plate 14. A limiting groove 16 is provided on the right outer wall of the second fixed seat 2 at a position corresponding to the fixed block 1401.

[0026] A first mounting plate 17 is fixedly mounted on the front end outer wall of the second fixed seat 2, a latch 18 is slidably mounted on the first mounting plate 17, a second spring 19 is fixedly mounted on the top end of the latch 18, and the bottom end of the second spring 19 is fixedly connected to the top end of the first mounting plate 17. A second mounting plate 20 is fixedly mounted on the front end outer wall of the first fixed seat 1 below the first mounting plate 17, and a limiting hole 21 is provided on the second mounting plate 20 at a position corresponding to the latch 18.

[0027] When the staff closes the first fixing seat 1 and the second fixing seat 2 to clamp the pipe, the limit plate 14 is engaged with the limit groove 16 under the action of the first spring 15. At the same time, the staff can pull the pin 18 upward, and then the pin 18 is engaged with the limit hole 21 under the action of the second spring 19. In addition, the setting of the second spring 19 reduces the possibility of the pin 18 being separated from the limit hole 21, thereby making the device more stable during construction and reducing the risk of the pipe slipping.
