[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1As shown in Embodiment 1, an adjustable span frame-type manual excavation pile hole lifting frame includes a support column 1, a connecting beam 2, a traveling track 3, diagonal braces 4, and a connecting plate 5. There are two support columns 1 and two sets of connecting beams 2, with two beams in each set. The two connecting beams 2 are arranged in parallel and distributed vertically. The support column 1 is fixedly installed at the center of the connecting beam 2. A fixed suspension beam 2-1 is fixedly installed at the top of the upper connecting beam 2 of each set. The traveling track 3 is fixedly installed at the center of the bottom end of the fixed suspension beam 2-1 and is arranged parallel to the connecting beam 2. A winch 3-1 is slidably installed on the traveling track 3. There are moving rods 6 on both sides of the support column 1. There are four sets of diagonal braces 4, with two beams in each set. The two diagonal braces 4 are rotatably installed at the upper and lower ends of the moving rods 6, respectively. The ends of the two diagonal braces 4 away from the moving rods 6 are rotatably installed on the two ends of the connecting plate 5, and the two diagonal braces 4 are staggered. The connecting plate 5 is installed on the support column 1.

[0021] When in use, first install the support column 1, connecting beam 2, traveling track 3 and winch 3-1 around the opening of the manually excavated pile hole. After installation, adjust the distance between the two moving rods 6 according to the specifications of the anchor pile so that the lifting frame can be used for anchor piles of different specifications.

[0022] After the distance of the moving rod 6 is adjusted, the diagonal tie rod 4 is connected to the end of the connecting plate 5 to make the installation between the moving rod 6 and the support column 1 more stable. When the distance between the moving rod 6 and the support column 1 is large, the upper diagonal tie rod 4 is connected to the top of the connecting plate 5 and the lower diagonal tie rod 4 is connected to the bottom of the connecting plate 5. When the distance between the moving rod 6 and the support column 1 is small, the upper diagonal tie rod 4 is connected to the bottom of the connecting plate 5 and the lower diagonal tie rod 4 is connected to the top of the connecting plate 5.

[0023] Adjustable pads 2-2 are evenly distributed on the opposite surfaces of each set of connecting beams 2. The moving rod 6 is detachably installed on the adjustable pads 2-2. The connecting plate 5 is fixedly installed on the side of the support column 1. The end of the diagonal tie rod 4 is detachably installed on the end face of the connecting plate 5. The connecting beam 2 is provided with a stabilizing rod 6-3, which is correspondingly set with the moving rod 6.

[0024] When it is necessary to adjust the distance between the movable rod 6 and the connecting beam 2, the movable rod 6 can be connected to the adjustable pads 2-2 at different positions, so that the movable rod 6 can be used for anchor piles of different specifications. After the movable rod 6 and the adjustable pads 2-2 are installed, the connection stability between the movable rod 6, the support column 1 and the connecting beam 2 can be increased. At this time, the stabilizing rod 6-3 can be displaced, making the overall stability of the device better.

[0025] In Embodiment 1, when adjusting the position of the moving rod 6, the end of the diagonal tie rod 4 is separated from the connecting plate 5. After separation, the position of the moving rod 6 is adjusted, and then the positions of the ends of the two diagonal tie rods 4 are changed to achieve the effect of changing the size of the lifting frame.

[0026] like Figures 2 to 5 As shown, in Embodiment 2, the movable rod 6 is slidably mounted on the connecting crossbeam 2. The top of the movable rod 6 is provided with a sliding sleeve 6-1, which is slidably mounted on the upper connecting crossbeam 2. The bottom of the movable rod 6 is provided with a buckle 6-2, which is snapped onto the lower connecting crossbeam 2. A stabilizing rod 6-3 is fixedly installed between the two sliding sleeves 6-1.

[0027] In use, the movable rod 6 is slid on the connecting beam 2, so that the sliding sleeve 6-1 and the buckle 6-2 move on the connecting beam 2, so that the movable rod 6 can remain relatively stable when adjusting its position. The upper part of the sliding sleeve 6-1 contacts the connecting beam 2, which makes the connection between the movable rod 6 and the connecting beam 2 more stable. The lower part of the movable rod 6 contacts the connecting beam 2, which allows the bottom end of the movable rod 6 to slide on the lower connecting beam 2, making it easy to change its position.

[0028] The connecting plate 5 is detachably installed on the support column 1. Each set of connecting crossbeams 2 has a movable plate 6-4 inside both ends. The movable plate 6-4 is provided with a limiting block 6-5 at equal intervals. The end of the limiting block 6-5 passes through the crossbeam 2 and can lock the two ends of the sliding sleeve 6-1. The opposite ends of the two movable plates 6-4 are fixedly installed with extension rods 6-6. The extension rods 6-6 are slidably installed inside the support column 1.

[0029] When the moving plate 6-4 moves, it can drive the limiting block 6-5 to move. When the moving plate 6-4 drives the limiting block 6-5 to retract into the connecting beam 2, the limiting block 6-5 will not block the movement of the moving rod 6 on the connecting beam 2, so that the sliding sleeve 6-1 and the buckle 6-2 can both slide on the connecting beam 2.

[0030] When the moving plate 6-4 moves the limiting block 6-5 to pass through the connecting beam 2, the limiting block 6-5 can lock the two sides of the sliding sleeve 6-1 and the buckle 6-2, so that the sliding sleeve 6-1 and the buckle 6-2 are blocked by the limiting block 6-5, preventing the moving rod 6 from moving on the connecting beam 2 and ensuring the overall stability of the lifting frame.

[0031] An insert rod 6-7 is fixedly installed at the bottom end of the extension rod 6-6. The insert rod 6-7 is L-shaped. Insert plates 5-1 are fixedly installed on both sides of the connecting plate 5. The end of the insert rod 6-7 can be flipped onto the insert plate 5-1.

[0032] When the movable plate 6-4 moves, it can drive the extension rod 6-6 to move. The extension rod 6-6 can drive the insertion rod 6-7 to move. When the insertion rod 6-7 is upside down on the insertion plate 5-1, it can restrict the movement of the insertion rod 6-7, so that the extension rod 6-6 drives the movable plate 6-4 to be locked on the insertion plate 5-1, so that the limit block 6-5 can be locked, allowing the movable rod 6 to be stably installed on the connecting beam 2. At the same time, the insertion rod 6-7 can lock the insertion plate 5-1, allowing the connecting plate 5 to be stably installed on the support column 1.

[0033] Both ends of the back side of the plug plate 5-1 are set as inclined surfaces 5-2. Both ends of the plug plate 5-1 are provided with plug grooves 5-3. The plug rod 6-7 can be inserted into the plug groove 5-3. The plug plate 5-1 can be inserted into the center of the support column 1. The end of the plug rod 6-7 is fixedly installed with a drive rod 6-8. The end of the drive rod 6-8 passes through the support column 1 and is slidably installed on the support column 1.

[0034] When the plug plate 5-1 is inserted into the support column 1, the inclined surface 5-2 of the plug plate 5-1 will press the plug rod 6-7, so that the plug rod 6-7 can move relative to the moving plate 6-4 along the guiding action of the inclined surface 5-2, so that the plug rod 6-7 passes over the plug plate 5-1. When the plug rod 6-7 is within the range of the plug groove 5-3, the plug rod 6-7 is inserted into the plug groove 5-3, so that the plug rod 6-7, the connecting plate 5 and the limiting block 6-5 can lock each other, ensuring the overall stability of the lifting frame;

[0035] When it is necessary to remove the insertion rod 6-7 from the insertion slot 5-3, the insertion rod 6-7 is moved by moving the drive rod 6-8, so that the insertion rod 6-7 can be pulled out from the insertion slot 5-3, thus achieving the effect of moving the moving rod 6.

[0036] An elastic lever 5-4 is provided between the moving rod 6 and the interior of the connecting beam 2. The elastic lever 5-4 is fixedly installed inside the connecting beam 2. When the moving rod 6 moves to the maximum distance, the end of the limiting block 6-5 retracts into the interior of the connecting beam 2.

[0037] When the elastic lever 5-4 is in its initial position, it enables the limiting block 6-5 to remain extended from the connecting beam 2, thus maintaining the stability of the moving rod 6. At the same time, when the plug plate 5-1 is inserted into the support column 1, the guiding effect of the inclined surface 5-2 causes the moving plate 6-4 to press the elastic lever 5-4. Furthermore, when the plug rod 6-7 is located inside the plug groove 5-3, the elastic lever 5-4 inserts the plug rod 6-7 into the plug groove 5-3, thereby achieving a stable overall effect for the device.

[0038] Compared to Embodiment 1, Embodiment 2 eliminates the need for connecting the inclined tie rod 4 and the moving rod 6. Instead, the moving rod 6 and the connecting beam 2 are unlocked by the moving drive rod 6-8. The moving rod 6 can be directly slid to control its spacing. When the connecting plate 5-1 is inserted into the support column 1, the entire lifting frame can be automatically locked, achieving the effect of maintaining the overall stability of the lifting frame.

[0039] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
