[0020] The technical solution of the present application has at least the following advantages and beneficial effects:

[0021] 1. When hoisting the cover plate, first place the hoisting device on the ground, then pull the bottom plates on both sides to straighten the connecting ropes, then place the cover plate to be hoisted on the bottom plate, then use the shielding piece to form a shield at the end of the cover plate, so that the cover plate is placed between the bottom plate and the shielding, thereby reducing the possibility of the cover plate falling off the bottom plate during the hoisting process; then connect the hoisting rope to the suspension beam, then connect the suspension beam to the hoisting device, and then hoist the cover plate to the required place through the hoisting device; when After the cover is hoisted to the required location, it falls to the designed location. Since the cover is pressed on the bottom plate, it is difficult to separate the cover and the bottom plate, which makes it difficult for the hoist to quickly carry out the next batch of hoisting operations. Therefore, the cover is removed from the bottom plate by the removal member, and then the cover is stacked to the required location, which makes it easy to remove the hoist in time, thereby improving the hoisting efficiency of the cover; when the cover is hoisted, impurities or gravel falling from the cover fall on the sealing cloth, which improves the safety of the cover hoisting;

[0022] 2. When it comes to standard-shaped cover plates such as squares and rectangles, place the cover plate on the bottom plate for hoisting; for cover plates such as arcs, place the convex surface of the cover plate on the bottom plate, then stack the cover plates on the bottom cover plate in sequence, and then hang the hoisting rope on the suspension beam. At this time, the hoisting rope drives the bottom plate to fit on the arc surface of the cover plate, and then hoist the arc-shaped cover plate; for irregular-shaped cover plates, place the protruding part of the cover plate in the gap between adjacent bottom plates, and then adjust the position of the bottom plate to make the bottom plate fit on the cover plate, so as to hoist the irregular-shaped cover plate. Therefore, for cover plates of different shapes, a lifting tool is used for hoisting, which reduces the time for replacing the lifting tool and thus improves the hoisting speed of the cover plate;

[0023] 3. When the lifting tool is being transported, wind the bottom plate into a column shape, and then wind the wound bottom plate with the hoisting rope, thereby reducing the space occupied by the lifting tool and facilitating the transportation of the lifting tool.

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0043] The following is further described in conjunction with specific embodiments, with reference to Figure 1, the precast cover plate hoisting device includes a traveling device 1, a hoisting device 2, and a sling 3. The sling 3 is used to hook the cover plate 4. The hoisting device 2 acts on the sling 3 to lift or lower the cover plate 4. The hoisting device 2 is arranged on the traveling device 1 and changes its position through the traveling device 1. In the embodiment of the present application, the traveling device 1 includes an automobile chassis 11 and traveling wheels 12 arranged on the automobile chassis 11. The hoisting device 2 includes a multi-stage telescopic rod 21 arranged on the automobile chassis 11 and a winch 22 arranged on the automobile chassis 11. A steel wire rope 23 is wound on the winch 22;

[0044] Referring to Figure 2 and Figure 3 , the sling 3 includes a plurality of bottom plates 31. The bottom plates 31 are strip-shaped and arranged horizontally and at intervals. A connecting rope 32 is arranged between adjacent bottom plates 31. In the embodiment of the present application, the connecting rope 32 is a steel chain and is fixedly arranged on the side wall of the bottom plate 31. A plurality of connecting ropes 32 are arranged between adjacent bottom plates 31 and the connecting ropes 32 are parallel to each other. A sealing cloth is arranged between adjacent bottom plates 31. The sealing cloth is located below the connecting rope 32. The width of the sealing cloth is greater than the length of the connecting rope 32, thereby reducing the possibility of damage to the sealing cloth caused by excessive straightening. The sling 3 further includes a suspension beam 33 and a hoisting rope 34. The hoisting rope 34 is made by winding a plurality of steel wire ropes 23. The hoisting rope 34 is arranged on the side walls of the bottom plates 31 at both ends. The other end of the hoisting rope 34 is fixedly arranged on the suspension beam 33. The suspension beam 33 is used to be arranged on the hoisting device 2.

[0045] Referring to Figure 2 and Figure 3 , when hoisting the cover plate 4, place the cover plate 4 on the bottom plate 31, then fix the hoisting rope 34 on the side of the cover plate 4 to the suspension beam 33. Subsequently, hang the suspension beam 33 on the steel wire rope 23 of the winch 22, and then start the winch 22. The winch 22 winds the steel wire rope 23 to hoist the cover plate 4, and the operation is simple and convenient; at the same time, the sealing cloth blocks the gap between adjacent bottom plates 31, thereby improving the safety of hoisting the cover plate 4.

[0046] Referring to Figure 4 , to reduce the possibility that the cover plate 4 slides and falls on the bottom plate 31 due to the inclination of the cover plate 4 during hoisting, shielding members 5 are arranged on both transverse end faces of the bottom plate 31. The shielding members 5 are used to form a shield on the end face of the bottom plate 31 after the cover plate 4 is placed on the bottom plate 31 to limit the cover plate 4; through the shielding members 5, a shield is formed at the end of the cover plate 4, so that the cover plate 4 is placed between the bottom plate 31 and the shield, thereby reducing the possibility that the cover plate 4 falls off the bottom plate 31 during hoisting, and thus improving the safety of hoisting the cover plate 4.

[0047] Referring to Figure 4 and Figure 5, the bearing surface of the bottom plate 31 is provided with a removal piece 6, and the removal piece 6 is used to remove the cover plate 4 on the bottom plate 31 after the cover plate 4 is lowered to the ground; when the cover plate 4 is hoisted to the required place, the cover plate 4 falls to the designed place, because the cover plate 4 is pressed on the bottom plate 31, it is difficult to separate the cover plate 4 and the bottom plate 31, which makes it difficult for the sling 3 to quickly carry out the next batch of hoisting operations. Therefore, the removal piece 6 acts on the cover plate 4 to remove the cover plate 4 from the bottom plate 31, and then the cover plate 4 is stacked to the required place, which is convenient for timely removal of the sling 3, thereby improving the hoisting efficiency of the cover plate 4.

[0048] Reference Figure 6 , Figure 7 and Figure 8 In the embodiment of the present application, the removal member 6 includes a load-bearing wheel 61 arranged on the bottom plate 31, the load-bearing wheel 61 is rotatably arranged on the bottom plate 31, the rotation axis of the load-bearing wheel 61 is parallel to the width direction of the bottom plate 31, a plurality of load-bearing wheels 61 are arranged and are evenly arranged along the length direction of the bottom plate 31, a mounting groove is opened on the bearing surface of the bottom plate 31, the load-bearing wheel 61 is located in the mounting groove, the top surface of the load-bearing wheel 61 is located below the receiving surface of the bottom plate 31, the load-bearing wheel 61 is slidably arranged in the mounting groove, and the load-bearing wheel 61 slides along the depth direction of the mounting groove, and the removal member 6 also includes a driving member for driving the load-bearing wheel 61 to slide and carry the cover plate 4;

[0049] Reference Figure 6 , Figure 7 and Figure 8 Furthermore, an installation cavity 7 is opened in the bottom plate 31, and the installation cavity 7 is a rectangular cavity. The installation groove is connected to the installation cavity 7. The driving member includes a bearing plate 62 arranged in the installation cavity 7 and a bearing airbag 63 arranged in the installation cavity 7. The bearing plate 62 is located on the bearing airbag 63, and the bearing wheel 61 is arranged on the bearing plate 62. The driving member includes an air pump arranged on the bottom plate 31, and the air pump is connected to the air inlet of the bearing airbag 63.

[0050] When the cover plate 4 is hoisted, the load-bearing wheel 61 is received in the installation groove, so that the cover plate 4 is supported on the base plate 31, and the contact surface between the cover plate 4 and the base plate 31 is increased, thereby reducing the possibility of the cover plate 4 sliding on the base plate 31, thereby improving the safety of the hoisting of the cover plate 4; when the cover plate 4 is hoisted and transported to the required position, the air pump is started, and the air pump injects compressed gas into the load-bearing airbag 63. The volume of the load-bearing airbag 63 increases and lifts the load-bearing plate 62. The load-bearing plate 62 moves out of the installation groove and lifts the cover plate 4, thereby separating the cover plate 4 from the base plate 31, and then pushing the cover plate 4 to move on the load-bearing wheel 61, which facilitates the separation of the cover plate 4 from the sling 3, thereby facilitating the removal of the cover plate 4.

[0051] Reference Figure 6 , Figure 7 and Figure 8, since the cover plate 4 is crimped on the bottom plate 31, when the load-bearing airbag 63 expands, it is difficult for the load-bearing airbag 63 to expand evenly. As a result, it is difficult for the load-bearing plate 62 to be in a horizontal state and move upward. Therefore, in the embodiment of the present application, the driving member further includes a guide rod 64 disposed in the installation cavity 7, and the load-bearing plate 62 slidably passes through the guide rod 64; under the action of the guide rod 64, the sliding of the load-bearing plate 62 is guided, so that the load-bearing plate 62 moves upward in a balanced state, thus facilitating the load-bearing airbag 63 to lift the load-bearing plate 62 and facilitating the load-bearing wheel 61 to abut against the cover plate 4.

[0052] Refer to Figure 6 , Figure 7 and Figure 8 , to facilitate the removal of the cover plate 4 from the bottom plate 31 after the load-bearing wheel 61 abuts against the cover plate 4, a driving belt 65 is wound around the load-bearing plate 62, and two installation notches 8 are formed in the load-bearing plate 62. The installation notches 8 are respectively close to the ends of the load-bearing plate 62. A driving roller 66 is rotatably disposed in the installation notch 8, the driving belt 65 is wound around the driving roller 66, the conveying surface of the driving belt 65 abuts on the load-bearing plate 62 and the load-bearing wheel 61 abuts on the driving belt 65. Further, an avoidance groove is formed in the bottom surface of the load-bearing plate 62, and the driving belt 65 is located in the avoidance groove so that the driving belt 65 is separated from the load-bearing airbag 63, thereby reducing the influence of the load-bearing airbag 63 on the operation of the driving belt 65. Further, a driving motor 67 is disposed in the installation notch 8, and the driving roller 66 is coaxially disposed on the output shaft of the driving motor 67. After the load-bearing plate 62 drives the load-bearing wheel 61 to abut against the cover plate 4, the driving motor 67 is started, the driving motor 67 drives the driving roller 66 to operate, the driving roller 66 drives the driving belt 65 to operate, the driving belt 65 drives the load-bearing wheel 61 to rotate, and the load-bearing wheel 61 rotates to drive the cover plate 4 to move, thus facilitating the removal of the cover plate 4 from the lifting tool 3.

[0053] Refer to Figure 6 and Figure 9 , in the embodiment of the present application, the shielding member 5 includes a shielding plate disposed at the end of the bottom plate 31 and a shielding net 51 disposed between adjacent shielding plates. The shielding net 51 is used to connect adjacent shielding plates and is in a straightened state; after the cover plate 4 is placed on the bottom plate 31, the shielding net 51 closes the adjacent shielding plates, thereby forming a shield at the end of the bottom plate 31, reducing the possibility of the cover plate 4 falling off the bottom plate 31, and improving the safety of lifting the cover plate 4.

[0054] Refer to Figure 6 and Figure 9, Further, the baffle includes a sliding plate 52 and a mounting plate 53. The sliding plate 52 is strip-shaped and parallel to the length direction of the bottom plate 31. The mounting plate 53 is hingedly arranged on the sliding plate 52. Further, a receiving groove 9 is formed on the sliding plate 52, and the mounting plate 53 is hinged in the receiving groove 9. The hinge axis of the mounting plate 53 is close to the end of the bottom plate 31, and the hinge axis of the mounting plate 53 is parallel to the width direction of the bottom plate 31. A sliding groove 27 for the sliding plate 52 to slide is formed on the end face of the bottom plate 31. Further, a guiding block protrudes from the side wall of the sliding plate 52, and a guiding groove for the guiding block to slide is formed on the side wall of the sliding groove 27. The length direction of the guiding groove is parallel to the length direction of the sliding plate 52, and both ends of the guiding groove are closed. After the sliding plate 52 drives the mounting plate 53 out of the sliding groove 27, the sliding plate 52 rotates to an inclined state, and the shielding net 51 is arranged on the side wall of the mounting plate 53; after the cover plate 4 is placed on the bottom plate 31, the sliding plate 52 is slid out of the sliding groove 27, and then the mounting plate 53 is rotated to make the mounting plate 53 in an inclined state. Then, the shielding net 51 is connected to the adjacent mounting plate 53 to protect the end of the bottom plate 31.

[0055] Refer to Figure 6 and Figure 9 , in the embodiment of the present application, after the mounting plate 53 rotates to a state perpendicular to the sliding plate 52, the plate surface of the mounting plate 53 abuts against the side wall of the receiving groove 9 to make the mounting plate 53 in a vertical state; further, a torsion spring 54 is sleeved on the hinge shaft of the mounting plate 53. One side of the torsion spring 54 is fixedly arranged on the side wall of the receiving groove 9, and the other side is fixedly arranged on the hinge shaft. The torsion spring 54 drives the mounting plate 53 to have a movement tendency to rotate out of the receiving groove 9; when the sliding plate 52 slides out of the sliding groove 27, the sliding plate 52 drives the end of the mounting plate 53 to move out of the sliding groove 27. Under the action of the torsion spring 54, the mounting plate 53 is driven to rotate out of the receiving groove 9, and the operation is simple and convenient.

[0056] Refer to Figure 6 and Figure 9 , to facilitate the connection of the shielding net 51 between adjacent mounting plates 53, a connecting rod 10 is arranged at the end of the shielding net 51, and a connecting groove for the connecting rod 10 to be clamped is formed on the adjacent connecting rod 10. In the embodiment of the present application, a dovetail block 13 is arranged on the connecting rod 10, and the connecting groove on the other connecting rod 10 is a dovetail groove 14 for the dovetail block 13 to be inserted; after the mounting plate 53 rotates out, the shielding net 51 is pulled to make the dovetail block 13 inserted into the dovetail groove 14, so as to complete the connection of the shielding net 51, and the operation is simple and convenient.

[0057] Refer to Figure 6 and Figure 9 , further, a groove 15 is recessed in the side wall of the mounting plate 53, and a winding shaft is rotatably arranged in the groove 15, and the shielding net 51 is wound on the winding shaft, so as to facilitate the storage of the shielding net 51.

[0058] Refer toFigure 2 and Figure 7 When the length of the cover plate 4 is relatively large, in order to facilitate the hoisting of such a cover plate 4, extension rods 16 are provided at the end of the bottom plate 31 and on both sides of the sliding groove 27, and an extension groove 17 for inserting the extension rods 16 is formed at the other end of the bottom plate 31; when hoisting the cover plate 4 with a relatively large length, multiple sets of lifting tools 3 are placed on the ground, and then the lifting tools 3 are spliced. When splicing the lifting tools 3, the extension rods 16 are inserted into the extension grooves 17, and the splicing of the lifting tools 3 is completed, so as to facilitate the hoisting of the cover plate 4 with a relatively large length.

[0059] Refer to Figure 2 、 Figure 3 and Figure 4 In the embodiment of the present application, when hoisting the cover plate 4 with a regular shape or the cover plate 4 with an arc shape, the bottom plate 31 and the suspension rope exert a relatively large pressure on the edge of the cover plate 4, which is likely to cause damage to the cover plate 4. Therefore, in the embodiment of the present application, a pressing rod 18 is provided at the bottom of the suspension beam 33. The pressing rod 18 is hinged at the bottom of the suspension beam 33, and the hinge axis of the pressing rod 18 is parallel to the length direction of the suspension beam 33. A pressing plate 19 is provided at the end of the pressing rod 18 away from the suspension beam 33. The pressing plate 19 is spherical-hinged at the end of the pressing rod 18. The pressing rod 18 is a telescopic structure. Further, a multi-stage cylinder is provided on the pressing rod 18 to drive the pressing rod 18 to extend or shorten. The pressing rod 18 expands and contracts to drive the pressing plate 19 to press against the edge of the cover plate 4.

[0060] After the cover plate 4 is hoisted by the lifting tool 3 and separated from the ground, the pressing rod 18 is rotated to make the pressing rod 18 drive the pressing plate 19 to be placed at the edge of the cover plate 4. Then, the multi-stage cylinder is started, and the multi-stage cylinder drives the pressing rod 18 to extend. The extension of the pressing rod 18 makes the pressing plate 19 press against the edge of the cover plate 4, and applies pressure to the edge of the cover plate 4, thereby reducing the possibility of damage to the cover plate 4 caused by the suspension rope.

The length direction of the lead screw 25 is parallel to the length direction of the suspension beam 33. The mounting seat 20 is threadedly connected to the lead screw 25, and a moving motor 26 is arranged on the suspension beam 33. The lead screw 25 is coaxially arranged on the output shaft of the moving motor 26; when the moving motor 26 is started, the moving motor 26 drives the lead screw 25 to rotate, the rotation of the lead screw 25 drives the mounting seat 20 to move, and the movement of the mounting seat 20 drives the crimping rod 18 to move, so as to facilitate the crimping plate 19 to be crimped on the edge of the cover plate 4 and facilitate the crimping of cover plates 4 of different specifications.

[0062] The implementation principle of a prefabricated cover plate hoisting device in the embodiment of the present application is as follows:

[0063] When hoisting the cover plate 4, first place the hoisting tool 3 on the ground, then pull the bottom plates 31 on both sides to make the connecting ropes 32 in a straightened state, and then place the cover plate 4 to be hoisted on the bottom plates 31. Then drive the mounting plate 53 to slide out of the bottom plates 31 through the sliding plate 52, and then connect the shielding net 51. The shielding net 51 forms a shielding at the end of the cover plate 4, so that the cover plate 4 is placed between the bottom plates 31 and the shielding, thereby reducing the possibility of the cover plate 4 falling off the bottom plates 31 during hoisting.

[0064] Subsequently, connect the hoisting rope 34 to the suspension beam 33, and then connect the suspension beam 33 to the winch 22. Then hoist the cover plate 4 through the winch 22. At this time, start the moving motor 26, the moving motor 26 adjusts the position of the mounting seat 20, and then adjusts the position of the crimping rod 18 through the adjusting motor 24, so that the crimping plate 19 is crimped at the edge of the cover plate 4;

[0065] When the cover plate 4 is hoisted to the required position and the cover plate 4 falls to the designed position, start the air pump. The air pump injects compressed gas into the bearing airbag 63. The volume of the bearing airbag 63 increases to lift the bearing plate 62. The bearing plate 62 moves out of the installation groove to lift the cover plate 4, so that the cover plate 4 is separated from the bottom plates 31. Then push the cover plate 4 to move on the bearing wheels 61, which is convenient for the cover plate 4 to be separated from the hoisting tool 3, thereby facilitating the removal of the cover plate 4 and further facilitating the next hoisting of the hoisting tool 3.

[0066] The above are only the preferred embodiments of the application and are not intended to limit the application. For those skilled in the art, various changes and modifications can be made to the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included within the protection scope of the application.
