Description

Technical Field

[0001] The utility model relates to the technical field of curbstone lifting, in particular to a curbstone lifting device. Background Art

[0002] Curb, also known as "road curb" or "curb stone", is a precast concrete block or brick built between the carriageway and the sidewalk, which is higher than the road surface and basically level with the sidewalk. Its function is to protect the safety of pedestrians and form drainage at the edge of the carriageway. Curb stones need to be lifted when placed.

[0003] For example, a municipal engineering curbstone lifting device with the authorization announcement number "CN213802575U" moves the bracket to the rear of the transport vehicle body, and places the curbstone on the ground through the downward movement of the first electric telescopic rod. This setting is convenient for reducing the burden on the workers. However, since the fixing direction of the clamping plate of this municipal engineering curbstone lifting device cannot be adjusted, when lifting curbstones in different directions, the direction of the clamping plate cannot be adjusted according to the reverse direction of the curbstone, and workers are required to manually adjust the curbstone to the direction in which the clamping plate can be fixed, thereby increasing the limitations of the work. At the same time, since the working environment of this municipal engineering curbstone lifting device is outdoors, when it rains, the rain will wet the entire device, causing damage to the device and requiring repair, thereby increasing maintenance costs.

[0030] Working principle:

[0031] Curbstone lifting process:

[0032] When the curbstone needs to be lifted, the worker pushes the handrail 4, and the handrail 4 drives the frame 1 to move through the universal wheel. After the frame 1 moves to the working curbstone, the handrail 4 is stopped from being pushed, and then the external power supply of the two electric telescopic rods 14 is connected and started. The two electric telescopic rods 14 push the frame 5 to slide on the frame 1. After the frame 5 moves to a suitable position, the two electric telescopic rods 14 are closed, and the external power supply of the first servo motor 6 is connected and started. The first servo motor 6 drives the threaded rod 7 to rotate, and the threaded rod 7 drives the nut 8 to move. The nut 8 drives the first shell 201 to move and then drives the second cylinder 9 to move. The second cylinder 9 drives the box 10 to move, and the box 10 drives the two vertical plates 13 to move. After the two vertical plates 13 move to a suitable position, the first servo motor 6 is closed;

[0033] Then, the external power supply of the second cylinder 9 is connected and started. The second cylinder 9 drives the two vertical plates 13 to move downward according to the above method. After the vertical plates 13 move to the two sides of the curb, the second cylinder 9 is closed. Then, the external power supply of the second servo motor 11 is connected and started. The second servo motor 11 drives the stud 12 to rotate. The stud 12 drives the two vertical plates 13 to move relative to each other. After the surface of the two vertical plates 13 is pressed against the curb, the second servo motor 11 is closed. The curb is fixed in the above method, and then the second cylinder 9 is started. The second cylinder 9 drives the fixed curb to perform lifting work.

[0034] Adjust the vertical plate clamping direction process:

[0035] When facing a road curb with an inconsistent direction, the external power supply of the first cylinder 202 is turned on and started, and the first cylinder 202 drives the block 203 to move leftward (such as Figure 6 ), the block 203 drives the roller 204 to move through the slide groove, the roller 204 drives the gear plate 205 to rotate clockwise through the pin shaft, the gear plate 205 drives the gear 206 to rotate, the gear 206 drives the second cylinder 9 to rotate, the second cylinder 9 drives the box body 10 to rotate and then drives the two vertical plates 13 to rotate to change the clamping direction, after the two vertical plates 13 rotate to the appropriate position, the first cylinder 202 is closed, according to the above method, the retraction of the first cylinder 202 can drive the clamping direction of the two plates 13 to reset, and the clamping direction of the two vertical plates 13 can be changed according to the direction of the curb through the above method.

[0036] When it rains, the worker screws the first bolt 302 at the left end, and the first bolt 302 drives the vertical plate 303 to move downward through the bearing (such as Figure 7 ), after the vertical plate 303 and the horizontal block 304 are separated, the first bolt 302 is stopped to be screwed, and then the two horizontal blocks 304 are pushed to the right at the same time (at this time, the plastic sheet 306 is squeezed together), and the two horizontal blocks 304 drive the plastic sheet 306 to spread (such as Figure 2), after 304 moves to the right end, according to the above method, screw the first bolt 302 at the right end to make the vertical plate 303 fit with the surface of the horizontal block 304 to limit it, and use the plastic sheet 306 to block the frame 5 in the above method to prevent rainwater from entering the machine and causing damage. The notch at the right end can be connected with an external plastic sheet 306 to lengthen it and block the notch. The specific length of the plastic sheet 306 can be selected according to needs.
