Description

TECHNICAL FIELD

[0001] The utility model belongs to the construction technical field of inspection well, especially relate to a lifting device for inspection well shaft adjusting block. BACKGROUND

[0002] At present, the inspection well construction mostly uses the assembled prefabricated well, and the upper well shaft of the inspection well is gradually increased to the design elevation by using the adjusting block, however, in the lifting and assembling process of the adjusting block, the construction team usually punches the lifting hole and inserts the threaded steel bar into the lifting hole in order to save trouble, and then inserts the other end of the threaded steel bar into the wire rope or sling for lifting, which is not stable, has the security risk of hole falling, and also damages the side wall of the adjusting block, affecting the construction quality.

[0003] After searching, the prior art with the announcement number CN219823425U is a lifting device for inspection well, which is inserted into the channel in the vertical direction of the prefabricated inspection well through the protrusion and the sliding block, and then the protrusion and the sliding block are stretched out of the channel in the horizontal direction of the prefabricated inspection well, and then the position of the sliding block is adjusted by the sliding rod, so that the plug abuts against the side wall of the prefabricated inspection well, and at this time, the crane can be started to lift the prefabricated inspection well; but the device can only lift the inspection well with the channel or the through hole in the horizontal direction of the side wall, the contact area of the protrusion and the sliding block with the inspection well is small, and no other limiting mechanism is provided, so that when the inspection well with high height is lifted, the inspection well is easily inclined, which increases the construction difficulty.

[0004] After searching, the prior art with the announcement number CN220165620U is a simple lifting device for well shaft, which connects the lifting hole and the hoisting machinery through the lifting rope; then the hoisting machinery lifts the lifting device, and the arc-shaped steel plate of the clamping part is placed on both sides of the well shaft to be lifted; then the hoisting machinery lifts the lifting rope again, and the clamping part is stressed and shrunk under the action of the hoisting machinery, the lifting rope and the gravity, that is, the interval between the two arc-shaped steel plates is small, so that the well shaft is clamped, and the well shaft is lifted; finally, after the well shaft is installed and positioned, the hoisting machinery releases the lifting rope, and the clamping part is opened; the device only clamps the inspection well by applying pressure to the inspection well through the arc-shaped steel plate of the clamping part, and cannot support the inspection well, so that the inspection well is easily separated from the lifting device due to vibration or swing during lifting. SUMMARY

[0005] The utility model aims at overcoming the defects in the prior art, and provides a lifting device for inspection well shaft adjusting block, which positions the well shaft through the limiting mechanism to prevent the well shaft from being inclined due to external factors during lifting; and cooperates with the limiting mechanism through the protection mechanism to prevent the inserting rod from separating from the lifting hole, and to protect the wire rope or sling to prevent the wire rope or sling from being broken due to friction with the edge of the well shaft.

[0008] The device is also provided with a protective mechanism, which includes a protective shell, a threaded rod II, a handle, and a connecting tube; the protective shells are provided in pair, and one end of the pair of protective shells is rotatably connected together; the threaded rod II is rotatably connected to a connecting seat provided at the other end of the protective shell, and the top end of the threaded rod II is fixedly connected to the handle, and the bottom is threadedly connected to the connecting tube fixedly connected to the other end of the arc plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1) Pass the wire rope or sling on the lifting machinery through the hook at the top of the connecting rod, then insert the plug rod on the connecting rod into the lifting hole on the wellbore, then lift the sliding block to squeeze the spring, control the sliding blocks at the top and bottom of the arc plate to be located on both sides of a pair of slides and fit the outer wall of the connecting rod, then release the sliding block, and the spring resets and pushes the sliding block into the slide, thereby preventing the arc plate from separating from the connecting rod during the lifting of the wellbore; then, the threaded rod I cooperates with the rotating seat to drive the arc plate to expand and fit the outer wall of the wellbore, thereby limiting the position of the wellbore and preventing the wellbore from tilting during the lifting process; then the lifting machinery pulls the connecting rod upward through the wire rope or sling, so that the plug rod on the connecting rod lifts the wellbore, and finally the lifting machinery drives the connecting rod to transport the wellbore to the predetermined position for installation;

[0011] 2) Turn the handle to make the threaded rod II cooperate with the connecting tube, driving the protective shell to move toward the limit mechanism. At this time, under the control of the threaded rod II, the protective shell is Figure 1 As shown in the figure, it fits on the top of the wellbore to prevent the wire rope or sling from rubbing against the edge of the top of the wellbore and breaking; at the same time, it drives the inserted rod to tighten the lifting hole to prevent external factors from causing the wellbore to separate from the lifting device.
