DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0016] Combined with Figure 1 To Attachment Figure 2A tankway rope quick release device comprises a base plate 1, a notch 2 is opened in the middle of the front side of the base plate 1, lifting assemblies are symmetrically installed at both ends of the base plate 1, a tankway rope quick locking assembly 3 is hinged between the protruding ends of the two lifting assemblies, a tankway rope quick locking assembly 3 is also installed on the base plate 1 and between the two lifting assemblies, and the two tankway rope quick locking assemblies 3 are arranged on the same vertical plane;

[0017] Specifically, the lifting assembly is installed at both ends of the base plate 1 by bolts, the upper tankway rope quick clamping assembly 3 is hinged between the upper ends of the lifting assembly through a joint bearing, and the lower tankway rope quick clamping assembly 3 is installed directly below the upper tankway rope quick clamping assembly 3.

[0018] The tankway rope quick locking assembly 3 includes a rear baffle 301, a square notch 302 is opened in front of the rear baffle 301, ball grid frames 303 are installed on both sides of the square notch 302, a front baffle 304 is fixed to the front of the rear baffle 301 by bolts, columns 305 are fixed at both ends of the rear baffle 301 by bolts, a mounting plate 306 is fixed between the upper ends of the columns 305 by bolts, small hydraulic cylinders 307 are fixed at both ends of the lower side of the mounting plate 306 by bolts, a pair of wedge blocks 308 are installed between the ball grid frames 303, the protruding ends of the small hydraulic cylinders 307 are fixed to each of the wedge blocks 308 by bolts, and a through hole 309 for the tankway rope to pass through is opened in the middle of the mounting plate 306.

[0019] Specifically, during installation, the ball bearing grid frame 303 can be first installed on both side surfaces of the square notch 302, and then the front baffle 304 can be fixed in front of the rear baffle 301 by bolts. By extending the small hydraulic cylinder 307, the wedge block 308 can be inserted between the ball bearing grid frames 303, so that the tank rope can be inserted and clamped, and the tank rope can pass through the through hole 309.

[0020] The front baffle 304 includes side panels 3041 fixed to the front and rear sides of the rear baffle 301 by bolts, and tooth blocks 3042 are hinged on the inner sides of the side panels 3041. The two tooth blocks 3042 are staggered and inserted, and a fixing pin 3043 is inserted through the two tooth blocks 3042 from top to bottom.

[0021] Specifically, when the tank rope is passed through, it is not necessary to install and clamp the tank rope by passing it through, which is time-consuming and labor-intensive. In this structure, the tank rope can be clamped between the two wedge blocks 308 from the side by pulling out the fixing pin 3043 and opening the two tooth blocks 3042, which is more convenient.

[0022] The corresponding surfaces of the two wedge blocks 308 are both provided with arc-shaped recesses 310 .

[0023] The center point of the arc-shaped recess 310 and the center point of the through hole 309 are located on the same vertical line.

[0024] The lifting component is a hydraulic cylinder 4.

[0025] The hydraulic cylinder 4 and the small hydraulic cylinder 307 both have a pressure-maintaining self-locking function, that is, they can maintain pressure at any extended length, thereby maintaining the required length and facilitating subsequent movement.

[0026] Specific implementation of the present invention: When the present invention is used, the fixing pins 3043 at the upper and lower ends can be firstly pulled out, and then the tooth block 3042 can be rotated open, so that the tank rope can be passed through the through hole 309 and placed between the wedge blocks 308 from the side, and then the tooth block 3042 can be closed, and the fixing pin 3043 can be inserted to fix the tooth block 3042, and then the hydraulic cylinder 4 can be started to drive the upper tank rope quick clamping assembly 3 to rise in the idle stroke, and then the upper small hydraulic cylinder 307 can be used to extend, so as to Push the paired wedge blocks 308 between the ball grid frames 303 to clamp the tankway rope, then retract the hydraulic cylinder 4, and send the tankway rope through the tankway rope quick locking assembly 3 at the lower end into the tankway. Then the tankway rope can be locked by using the tankway rope quick locking assembly 3 at the lower end, and then retract the upper small hydraulic cylinder 307 to remove the wedge block 308, and then the hydraulic cylinder 4 is raised in idle stroke. The cycle is repeated to quickly send the tankway rope into the tankway, thereby completing the operation of quickly lowering the lifted object to the bottom of the well.

[0027] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
