[0015] In order to better understand the present invention, Figures 1 to 4 The implementation modes of the present utility model will be explained in detail.

[0016] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0017] See also Figures 1 to 4The utility model discloses a deep well pump hoisting device, comprising a hoisting plate 1 and a flange baffle 2, the main body of the hoisting plate 1 is made of steel plate or iron plate, and a drop hole 3 and a card slot 4 are respectively opened on the top and bottom thereof by cutting, the drop hole 3 is used for binding a hoisting rope, and the card slot 4 is used for clamping with the pump pipe flange; the hoisting plate 1 is provided with a latch slot 5 connecting the top of the card slot 4 between the drop hole 3 and the card slot 4, the latch slot 5 is provided with a latch 6 that slides up and down, the hoisting plate 1 is respectively welded with limit blocks 7 that cooperate with the latch 6 on the front and rear sides of the latch slot 5, the front and rear sides of the latch slot 5 are closed by the limit blocks 7, and the insertion depth of the latch 6 is limited downward; the flange baffle 2 comprises a main frame 8 composed of steel and iron welding, and a sliding baffle 9 is horizontally slidably arranged on the main frame 8, the left side of the sliding baffle 9 is provided with a through slot 10 for the bottom of the pump pipe to pass through, and the right side is provided with a push-pull handle 11 for moving the sliding baffle 9.

[0018] Different from the prior art, the fixing method between the lifting plate 1 and the pump pipe of the lifting device is different, specifically, Figure 2 As shown in , first insert one end of the flange of the pump pipe into the slot 4, and then insert the bottom end of the latch 6 into the central water hole of the pump pipe, so as to fix the pump pipe. When in use, the flange baffle 2 is placed flat above the wellhead, and the sliding baffle 9 is driven by the push-pull handle 11 to slide to the left on the main frame 8 to block the wellhead. The sliding baffle 9 is used to block the pump pipe on the lifting plate 1 to avoid the risk of the pump pipe falling into the well due to wire rope breakage or other unexpected circumstances. The through groove 10 on the sliding baffle 9 allows the bottom of the pump pipe to pass normally; when the sliding baffle 9 is pulled to slide to the right on the main frame 8 by the push-pull handle 11, the wellhead is cleared by the sliding baffle 9.

[0019] The preferred technical solution in this embodiment takes into account that the main bodies of the hanging plate 1 and the flange baffle 2 are made of steel and iron. Although the structural strength is strong, the mass is heavy and it includes two main parts, which is very inconvenient to move. Figure 1 and Figure 3 As shown in the figure, a limit block 12 is provided at the top of the left end of the main frame 8, a detachable limit bolt 13 is screwed at the top of the right end, and T-shaped slide rails 14 cooperating with the sliding baffle 9 are provided on the front and rear sides respectively.

The main frame 8 is provided with a support foot 15 at the bottom of the right end, and a wheel 16 corresponding to the support foot 15 is provided at the bottom of the left end; when the support foot 15 contacts the ground, friction is generated with the ground to limit the rotation of the wheel 16. At this time, only moving the sliding baffle 9 by pushing and pulling the handle 11 will not cause displacement of the main frame 8.

[0020] When the lifting device needs to be moved, Figure 4 As shown in the figure, first, place the hanging plate 1 on the left end of the main frame 8, and engage the limit block 12; then, pull the sliding baffle 9 to the right through the push-pull handle 11 to the limit bolt 13; finally, hold one end of the push-pull handle 11 and pull it upward to lift the supporting foot 15 off the ground, continue to pull the push-pull handle 11 and move it through the wheels 16 at the bottom.

[0021] The preferred technical solution in this embodiment is to facilitate the upward and downward movement of the latch pin 6. Figure 2 As shown in , the top end of the latch 6 is provided with a pulling end 17 extending to the front and rear sides. The pulling end 17 applies force to the latch 6 by pinching it, which is convenient for the staff to operate.

[0022] The preferred technical solution in this embodiment is as follows Figure 3 As shown in , an opening is provided on the left side of the main frame 8, and the opening is used to avoid the connecting pipe of the wellhead.

[0023] The preferred technical solution in this embodiment is to facilitate the operation of the staff. Figure 1 As shown in the figure, the push-pull handle 11 is tilted upward and to the right, so that its height is more suitable for workers who are squatting to operate.
