Technical Field

[0001] The utility model relates to the technical field of lifting, and more specifically to a drainage cover plate lifting device. Background Art

[0002] Due to the tight construction schedule and long service life, the traditional application construction method of drainage ditch cover has the disadvantages of long machine occupancy time, uneven installation, and low speed for personnel to carry the drainage cover for construction. This requires the use of drainage cover lifting device to achieve lifting installation.

[0003] In the public technical literature, the utility model patent of Chinese patent publication number CN210505358U discloses a lifting device. There are many devices currently used for lifting, such as cranes and crane trucks, but these devices are large in size and weight, difficult to use in remote places outdoors, and have poor applicability. The patent mainly makes the lifting device more convenient to carry and easy to place outdoors for use, so that the applicability of the lifting device is better; however, the lifting device still has the following defects:

[0004] When the lifting device lifts the drain cover plate, since the lengths and widths of the drain cover plates are different, the lengths of the hook harnesses are different when lifting drain cover plates of different sizes, which can easily cause the drain cover plate to tilt and fall during lifting, and the lifting application range is smaller. Therefore, it is necessary to provide a drain cover plate lifting device. Utility Model Content

[0008] Preferably, the bottom ends of the two lifting ropes are fixedly connected with hooks, and the two hooks are symmetrically arranged.

A rolling shaft wheel is rotatably connected inside the sleeve shaft block, and an I-shaped steel is rollingly connected to the lower part of the outer wall of the rolling shaft wheel, and support frames are welded to both ends of the I-shaped steel.

[0009] By adopting the above technical solution, according to the length and width of the drain cover plate, the rotating cap drives the transverse linkage screw to rotate, the transverse linkage screw rotates inside the transverse adjustment frame plate, the first threaded sleeve block slides to the right along the inside of the transverse adjustment frame plate under the action of the thread, and the second threaded sleeve block slides to the left inside the transverse adjustment frame plate at the same time, the longitudinal linkage screw is rotated to drive the second longitudinal threaded sleeve block to move forward under the action of the thread, and the first longitudinal threaded sleeve block moves backward under the action of the thread, the second longitudinal threaded sleeve block and the first longitudinal threaded sleeve block are close to each other and adjusted to a position matching the size of the drain cover plate, the four hooks are hung in the holes of the drain cover plate, and the lifting pillar is driven upward by a manual lifting hoist to realize the lifting operation.

By setting a two-way adjustment component, the horizontal linkage screw drives the first threaded sleeve block to slide to the right along the inside of the horizontal adjustment frame plate under the action of the thread, and the second threaded sleeve block slides to the left inside the horizontal adjustment frame plate. The longitudinal linkage screw drives the second longitudinal threaded sleeve block to move forward under the action of the thread, and the first longitudinal threaded sleeve block moves backward under the action of the thread, so that the four hooks can be adjusted horizontally and vertically.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-5 A drainage cover lifting device is shown, and a drainage cover lifting device is provided on the drainage cover lifting device. The setting of the two-way adjustment component can keep the length of the hook harness vertically the same when lifting drainage covers of different sizes, and the drainage cover is lifted evenly during lifting, and the lifting application range is wider. The specific structure of the two-way adjustment component is set as follows:

[0023] In some embodiments, as shown in the attached Figure 1-4 As shown, the bidirectional adjustment assembly includes a first threaded sleeve block 4 and a second threaded sleeve block 5 which are arranged on the outer wall of the transverse linkage screw 3 from left to right in sequence, the bottom ends of the first threaded sleeve block 4 and the second threaded sleeve block 5 are both welded with a longitudinal adjustment frame plate 6, a longitudinal linkage screw 7 is rotatably connected inside the longitudinal adjustment frame plate 6, the outer wall of the longitudinal linkage screw 7 is sequentially provided with a first longitudinal threaded sleeve block 8 and a second longitudinal threaded sleeve block 11 from front to back, and the bottom ends of the first longitudinal threaded sleeve block 8 and the second longitudinal threaded sleeve block 11 are both fixedly connected with a lifting rope 9;

[0024] The working principle of the drainage cover lifting device of this embodiment is as follows:

[0025] During bidirectional adjustment, according to the length and width of the drainage cover plate, the rotating cap 12 is rotated to drive the transverse linkage screw 3 to rotate, and the transverse linkage screw 3 rotates inside the transverse adjustment frame plate 2. The transverse linkage screw 3 drives the first threaded sleeve block 4 to slide to the right along the inside of the transverse adjustment frame plate 2 under the action of the thread. At the same time, the second threaded sleeve block 5 slides to the left inside the transverse adjustment frame plate 2, and the distance between the second threaded sleeve block 5 and the first threaded sleeve block 4 becomes smaller. When the lifting length is adjusted, the longitudinal linkage screw 7 is rotated again to drive the second longitudinal threaded sleeve block 11 to move forward under the action of the thread, and the first longitudinal threaded sleeve block 8 moves backward under the action of the thread, and the second longitudinal threaded sleeve block 11 and the first longitudinal threaded sleeve block 8 are close to each other, so that the first longitudinal threaded sleeve block 8 drives the lifting. The rope 9 moves the hook 10, and the four hooks 10 can be adjusted horizontally and vertically to a position matching the size of the drainage cover. The four hooks 10 are hung in the holes of the drainage cover, and the lifting pillar 1 is driven to move upward by the manual lifting hoist 13. The lifting pillar 1 drives the horizontal adjustment frame plate 2 to move upward, and the horizontal adjustment frame plate 2 drives the horizontal linkage screw 3 to move the first threaded sleeve block 4 and the second threaded sleeve block 5 upward. The first threaded sleeve block 4 drives the longitudinal adjustment frame plate 6 to move the longitudinal linkage screw 7 and the second longitudinal threaded sleeve block 11 upward. The lifting rope 9 drives the hook 10 to move the drainage cover up and lift it. The manual lifting hoist 13 is moved to drive the sleeve shaft block 14 to make the rolling shaft wheel 15 roll on the I-shaped steel 16, and the I-shaped steel 16 is supported by the support frame 17.

[0026] In some embodiments, as shown in the attached Figure 1-4 As shown, the bottom ends of the two lifting ropes 9 are fixedly connected with hooks 10, and the two hooks 10 are symmetrically arranged so that the four hooks 10 can be hung in the holes of the drainage cover plate to hook the drainage cover plate. One end of the transverse linkage screw 3 extends to the outside of the transverse adjustment frame plate 2 and is welded with a rotating cap 12. The vertical cross-sectional shape of the rotating cap 12 is set to be hexagonal, so that the rotating cap 12 can be turned to drive the transverse linkage screw 3 to rotate, which is convenient for rotating the transverse linkage screw 3. The top of the lifting pillar 1 is fixedly connected with a manual lifting Hoist 13, two sleeve shaft blocks 14 are fixedly connected above the outer wall of the manual lifting hoist 13, and a rolling shaft wheel 15 is rotatably connected inside the sleeve shaft block 14. An I-shaped steel 16 is rollingly connected below the outer wall of the rolling shaft wheel 15. Support frames 17 are welded at both ends of the I-shaped steel 16 to facilitate the movement of the manual lifting hoist 13 to drive the sleeve shaft block 14 to make the rolling shaft wheel 15 roll on the I-shaped steel 16. The I-shaped steel 16 is supported by the support frame 17, which facilitates the movement of the lifted drainage cover.

[0027] In some embodiments, as shown in the attached Figure 5As shown, the outer wall of the lifting pillar 1 is equidistantly distributed in a circular ring and fixedly connected with two first fixed support blocks 18, the opposite sides of the two first fixed support blocks 18 are welded with connecting collar blocks 19, and the inside of the connecting collar blocks 19 is welded with an inclined reinforcement bracket 20, and a second fixed support block 21 is welded between the inclined reinforcement bracket 20 and the lateral adjustment frame plate 2;

[0028] According to the upper structure, when supporting the transverse adjustment frame plate 2, the lifting pillar 1 supports the two first fixed support blocks 18, the first fixed support blocks 18 support the connecting ring blocks 19, the connecting ring blocks 19 support the inclined reinforcement bracket 20, and the inclined reinforcement bracket 20 supports the top end of the transverse adjustment frame plate 2. In this way, the connection between the transverse adjustment frame plate 2 and the lifting pillar 1 is more firmly connected, and it is not easy to cause a break between the lifting pillar 1 and the transverse adjustment frame plate 2.
