[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0034] In the present invention, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", "bottom" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are relational words determined only for the convenience of describing the structural relationships of the various parts or elements of the present invention, and do not specifically refer to any part or element in the present invention and should not be understood as limitations on the present invention.

[0035] Taking the rescue of a person who has fallen into a narrow deep well as an example, this embodiment discloses a rescue salvage device suitable for narrow spaces, such as Figure 1 As shown, it mainly includes a salvaging main pole 1, a supporting assembly 2, a binding device 3, a first traction rope 4 and a second traction rope 5.

[0036] The salvage main rod 1 is a telescopic rod formed by connecting 3-5 unit tubes end to end (omitted in the figure and simplified to one), and the rescue personnel can extend the salvage main rod 1 into the narrow well at the wellhead. Figure 2As shown, the supporting assembly 2 mainly includes a claw seat 6 and a supporting claw 7. The claw seat 6 is a square tube structure, and the upper end of the claw seat 6 is welded to the bottom end of the salvage main rod 1. Two connecting plates 71 symmetrically distributed on the left and right are provided at the tail end of the supporting claw 7. The two connecting plates 71 are rotatably connected to the left and right side walls of the bottom end of the claw seat 6 through a rotating shaft, so that the supporting claw 7 can rotate relative to the claw seat 6. A spring 72 is fixed on each connecting plate 71 near its front, and the other end of the spring 72 is fixed on the same side of the claw seat 6. Such a design can enable the supporting claw 7 to rotate relative to the claw seat 6 under the action of the spring 72. A claw shell 73 is sleeved on the supporting claw 7, and an adjusting bolt connected to the supporting claw 7 is provided on the claw shell 73. The claw shell 73 can adjust the position relative to the supporting claw 7, thereby changing the overall length of the supporting claw 7 to adapt to wells of different diameters.

[0037] like Figure 3-4 As shown, the supporting claw 7 needs to support the rescued person from the bottom. Before the supporting assembly 2 is sent to the bottom of the rescued person, the supporting claw 7 needs to remain vertically downward. After the supporting assembly 2 is sent to the bottom of the rescued person, the supporting claw 7 needs to be rotated to an L-shaped position with the claw seat 6. When the supporting claw 7 is vertically downward, the rear side of the connecting plate 71 is aligned with the rear side of the claw seat 6. A latch barrel is installed on the rear side of the claw seat 6. A claw-controlled latch 61 is inserted in the latch barrel. A limited baffle 62 is welded on the claw-controlled latch 61. The limited baffle 62 can fix the connecting plate 71 relative to the claw seat 6. The second traction rope 5 is connected to the upper end of the claw-controlled latch 61. The second traction rope 5 extends to the wellhead. When the rescuer pulls the second traction rope 5, the claw-controlled latch is disengaged, thereby releasing the constraint of the limited baffle 62 on the connecting plate 71, and the supporting claw 7 rotates under the action of the spring 72. In order to ensure that the supporting claw 7 needs to rotate to the position of forming an L shape with the claw seat 6, a claw limit block 63 and a claw limit spring pin 64 are installed on the left and right side walls of the claw seat 6. When the supporting claw 7 rotates to form an L shape with the claw seat 6, the claw limit block 63 is located on the front side of the connecting plate 71 to prevent the supporting claw 7 from further rotating, and the claw limit spring pin 64 is located on the rear side of the connecting plate 71 to prevent the claw 7 from rotating back during operation, thereby ensuring that the supporting claw 7 rotates to form an L shape with the claw seat 6. When the supporting claw 7 needs to be reset, the claw limit spring pin 64 is pressed, the supporting claw 7 is manually rotated in the opposite direction to the initial state, and the claw control latch 61 is inserted into the latch tube.

[0038] like Figure 5-6As shown, the binding device 3 includes an auxiliary sleeve 31, a hard rope loop 32 and a rope loop adjuster composed of an adjusting sleeve 33 and a T-shaped sleeve 34. The auxiliary sleeve 31 is sleeved on the salvage main rod 1 and can move relatively. The rope loop adjuster is installed on the side wall of the auxiliary sleeve 31, and the lower end of the adjusting sleeve 33 is connected to the middle position of the T-shaped sleeve 34. The upper end of the auxiliary sleeve 31 is connected to the first traction rope 4, and the first traction rope 4 can be extended to the wellhead position. The rescue personnel can control the relative position of the binding device 3 through the first traction rope 4. The hard rope loop 32 is made of steel wire rope to ensure its own rigidity. The head end of the hard rope loop 32 is fixed to the right end of the front side of the T-shaped sleeve 34, and the tail end passes through the left end of the front side of the T-shaped sleeve 34 and passes through the inner cavity of the T-shaped sleeve 34 and the adjusting sleeve in turn to extend outside the wellhead. Rescue personnel outside the wellhead can adjust the size of the rope loop of the hard rope outside the T-shaped casing 34 by controlling the tail end of the hard rope loop 32. Since the hard rope loop 32 has a certain rigidity, the rope loop outside the T-shaped casing 34 is always round, and will not be excessively deformed when moving down in the deep well, ensuring that it can be put on the rescue target.

[0039] Three vertical rollers 35 are provided near the left end of the T-shaped sleeve 34, and two horizontal rollers 36 are provided in the adjustment sleeve 33. The rope of the hard rope loop 32 passes through the rolling surfaces of the horizontal rollers 36 and the vertical rollers 35 in turn. Such a design can make the rope of the hard rope loop 32 smoothly distributed from horizontal to vertical, and reduce the friction resistance when the hard rope loop 32 is pulled. A slide rail 37 distributed up and down is installed near the upper end of the adjustment sleeve 33. A slider 38 that slides up and down is matched on the slide rail 37. A tension spring 39 is fixed on the slider 38. The other end of the tension spring 39 is fixed on the inner wall of the adjustment sleeve 33 at a position below the slide rail 37. The rope of the hard rope loop 32 passes through the tension spring 39 from bottom to top and is fixedly connected to the upper end of the tension spring 39. The design of the slide rail 37 ensures that when the hard rope loop 32 is pulled, a straight state is maintained to avoid knotting of the rope. The design of the tension spring 39 ensures that the hard rope loop 32 remains relatively unchanged in the absence of traction, thereby preventing the rope loop from shrinking when it moves downward in the deep well. Figure 7 As shown, in order to prevent the rope line from rotating and causing the rope loop to twist and deform when the hard rope loop 32 is operated at the wellhead, a buffer is connected in series on the rope line of the hard rope loop located in the adjusting sleeve 33. The buffer includes a buffer cylinder 8. The upper and lower ends of the buffer cylinder 8 are rotatably connected to a rotating column 9 through a deep groove ball bearing. The upper and lower rotating columns 9 are respectively connected to the rope line connection points of the hard rope loop 32.

[0040] The specific working process of the rescue salvage device suitable for narrow space of the present invention is as follows:

[0041] 1. First, the supporting claw is in the initial vertical state, and the rescuer controls the first traction rope, the second traction rope and the tail end of the hard rope loop with his hands, and adjusts the length of the salvage main rod to meet the requirements of reaching into the deep well;

[0042] 2. Then, the salvage main pole is controlled to extend into the narrow deep well with the binding device, and the distance between the binding device and the supporting assembly is controlled by pulling the first traction rope to adapt to the size of different rescue targets;

[0043] The supporting assembly is first extended under the person to be rescued, and the grabbing latch is disengaged by pulling the second traction rope, so as to release the constraint of the limit baffle on the connecting plate. Under the action of the spring, the supporting claw rotates to an L-shaped position with the claw seat, so that the supporting claw can support the person to be rescued;

[0044] 3. By controlling the first traction rope, the rope loop of the hard rope loop is put on the person to be rescued, and by pulling the tail end of the hard rope loop, the rope loop is tightened to bind the person to be rescued.

[0045] 4. Through the support method of the support component and the binding method of the binding device, rescue and salvage targets such as people or objects trapped in a narrow space can be lifted out flexibly and safely.

[0046] During the implementation of the present invention of rescuing and salvaging people or objects, the rescued person or object is tied to the salvage main pole to ensure that the rescued object does not fall off during the lifting process. With the assistance of the binding device, the safety factor is greatly improved and the rescue speed is also increased.
