[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] Example 1 A grille plate storage and lifting tool

[0040] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment includes a vertical suspension rod 4 with an external thread 41 on the top and a first suspension ring 11 fixed to the top of the suspension rod 4. The first suspension ring 11 is composed of a hollow cylindrical ring body and an inverted U-shaped hanging ring fixed to both sides of the cylindrical ring body, and the distance between the two branches of the inverted U-shaped hanging ring is greater than the diameter of the cylindrical ring body. The top of the suspension rod 4 is higher than the connection between the suspension rod 4 and the first suspension ring 11, but does not contact the first suspension ring 11. The inner surface of the cylindrical ring body is provided with a first internal thread 13 that matches the external thread 41 on the top of the suspension rod 4. The matching here means that the first suspension ring 11 can be detachably fixedly connected to the suspension rod 4 through the first internal thread 13 on the inner surface of the cylindrical ring body and the external thread 41 on the suspension rod 4.

[0041] In order to prevent the first lifting ring 11 from loosening from the lifting rod 4, a spare cap 2 is added in this embodiment, and the spare cap 2 has a second internal thread matched with the external thread 41 of the lifting rod 4, and the spare cap 2 and the lifting rod 4 are connected together through threaded matching. In addition, the projection of the spare cap 2 in the horizontal plane is located within the projection of the cylindrical ring body in the horizontal plane, so that it can be ensured that the spare cap 2 does not interfere with the first lifting ring 11 when rotating.

[0042] In order to further prevent the first suspension ring 11 from loosening from the suspension rod 4, in this embodiment, a transverse pin hole 3 is provided at the top of the suspension rod 4, and a safety pin matched with the pin hole 3 is provided. The pin hole 3 passes through the suspension rod 4, and the length direction of the pin hole 3 is perpendicular to the length direction of the suspension rod 4. The matching here means that the safety pin can be inserted into the pin hole 3 and fixedly connected with the suspension rod. At the same time, the length of the external thread 41 of the suspension rod 4 is greater than the sum of the lengths of the first internal thread 13 and the second internal thread. In this way, it can be ensured that after the suspension rod 4 is tightened with the cylindrical ring body and the spare cap 2, the top of the suspension rod 4 extends out of the spare cap 2 to facilitate the installation of the safety pin. By inserting the safety pin, the spare cap 2 and the first suspension ring 11 are prevented from loosening and disengaging at the same time, which plays a role of secondary insurance.

[0043] In this embodiment, a circular first tray 71 fixedly connected to the hanger 4 is provided at the bottom of the hanger 4, and the upper surface plane of the first tray 71 is perpendicular to the length direction of the hanger 4. Four supporting rods 6 are evenly distributed on the edge of the first tray 71, and the ends of the supporting rods 6 are connected to the first tray 71 through fixed axle pins 8. The head end of the supporting rod 6 rotates between the horizontal plane of the hanger 4 and the first tray 71 with the fixed axle pin 8 as the center, and the rotation angle is an obtuse angle: when rotating upward, it can only contact the hanger 4 at most; when rotating downward, it is limited by the fixed axle pin 8, so that the length direction of the supporting rod 6 is perpendicular to the length direction of the hanger 4 at most, and the upper surface of the supporting rod 6 is flush with the upper surface of the first tray 71. The head end of the supporting rod 6 is also provided with a bundling hole 5 perpendicular to the rotation plane of the supporting rod 6, which is convenient for the folding and recycling of this embodiment.

[0044] When this embodiment is not in use, it appears as Figure 1 In the folded state shown, the head ends of all the supporting rods 6 are in contact with the suspension rods 4, and the tie bands pass through the binding holes 5 of all the supporting rods 6 to fix the supporting rods 6. When the grating plate needs to be stored and hoisted, first move the embodiment to the side of the grating plate to be stored, untie the tie bands on the binding holes 5, and make the embodiment appear as shown. Figure 3 In the unfolded state shown, the upper surfaces of all the supporting rods 6 are flush with the upper surface of the first pallet 71. Then remove the safety pin, the spare cap 2 and the first lifting ring 11 at the pin hole 3 in turn. Next, move the grating plate to the top of the hanging rod 4, make the plane of the grating plate parallel to the plane of the first pallet 71, align the hole at the center of the grating plate with the hanging rod 4 and insert it so that the grating plate is in contact with the first pallet 71 and the supporting rod 6. Next, place the next grating plate to be stored above the previous grating plate according to the above method until the storage is completed or the height of the grating plate is not higher than the height of the first lifting ring 11 of this embodiment in the folded state. Finally, tighten the first lifting ring 11 and the spare cap 2 in turn, insert the safety pin into the pin hole 3, operate the lifting device to pull up the first lifting ring 11, and then complete the storage and lifting work of the grating plate.

[0045] When the grating plate is needed, the grating plate together with the present embodiment is placed on the ground by a lifting device, the safety pin, the spare cap 2 and the first lifting ring 11 are removed, all the grating plates are moved upward and taken out, and then the first lifting ring 11 and the spare cap 2 are tightened in sequence, and the safety pin is inserted into the pin hole 3, and finally the head ends of all the supporting rods 6 are contacted with the lifting rod 4, and the supporting rods 6 are fixed by passing the tying holes 5 of all the supporting rods 6 with the cable ties, so that the present embodiment is presented as follows Figure 1 The embodiment can be stored in the folded state shown. It should be noted that the number of the supporting rods 6 in the embodiment is four, which can be adjusted according to the actual situation. Considering the need for good load-bearing capacity when hoisting the grid plate and the influence of the tool's own weight, the number of the supporting rods 6 is four to six. In the embodiment, the shape of the first tray 71 is circular, which can be replaced by other shapes, as long as the supporting rods 6 can be evenly distributed on the edge of the first tray 71.

[0046] Example 2 A grille plate storage and lifting tool

[0047] like Figure 4 , Figure 5 and Figure 6 As shown, this embodiment includes a vertical suspension rod 4 with an external thread 41 on the top and a second suspension ring 12 fixed to the top of the suspension rod 4. The second suspension ring 12 is composed of a hollow cuboid and an inverted V-shaped hanging ring fixed to the top of the cuboid, and the maximum distance between the two branches of the inverted V-shaped hanging ring is greater than the diameter of the suspension rod 4. The top of the suspension rod 4 is higher than the connection between the suspension rod 4 and the second suspension ring 12, but does not contact the second suspension ring 12.

[0048] The cuboid side surface of the second lifting ring 12 is provided with a through hole 14 perpendicular to the suspension rod 4, and the through hole 14 passes through the cuboid and the suspension rod 4. A matching fixing pin is provided at the through hole 14, and matching here means that the second lifting ring 12 and the suspension rod 4 can be fixedly connected by inserting the fixing pin.

[0049] In order to prevent the second lifting ring 12 from loosening from the suspension rod 4, a spare cap 2 is added in this embodiment, and the spare cap 2 has a second internal thread that matches the external thread 41 of the suspension rod 4, and the spare cap 2 and the suspension rod 4 are connected together through threaded matching. And the spare cap 2 does not interfere with the second lifting ring 12 when rotating.

[0050] In order to further prevent the second suspension ring 12 from loosening from the suspension rod 4, in this embodiment, a transverse pin hole 3 is provided at the top of the suspension rod 4, and a safety pin matched with the pin hole 3 is provided. The pin hole 3 passes through the suspension rod 4, and the length direction of the pin hole 3 is perpendicular to the length direction of the suspension rod 4. The matching here means that the safety pin can be inserted into the pin hole 3 and fixedly connected with the suspension rod. At the same time, the length of the external thread 41 of the suspension rod 4 is made greater than the length of the second internal thread, so that after the suspension rod 4 and the spare cap 2 are tightened, the top of the suspension rod 4 can be extended from the spare cap 2 to facilitate the installation of the safety pin. By inserting the safety pin, the spare cap 2 and the second suspension ring 12 can be prevented from loosening and disengaging at the same time, thereby playing a role of secondary insurance.

[0051] In this embodiment, a rectangular second tray 72 fixedly connected to the hanger 4 is provided at the bottom of the hanger 4, and the upper surface plane of the second tray 72 is perpendicular to the length direction of the hanger 4. Four supporting rods 6 are evenly distributed on the edge of the second tray 72, and the ends of the supporting rods 6 are connected to the second tray 72 through fixed axle pins 8. The head end of the supporting rod 6 rotates between the horizontal plane of the hanger 4 and the second tray 72 with the fixed axle pin 8 as the center, and the rotation angle is an obtuse angle: when rotating upward, it can only contact the hanger 4 at most; when rotating downward, it is limited by the fixed axle pin 8, so that the length direction of the supporting rod 6 is perpendicular to the length direction of the hanger 4 at most, and the upper surface of the supporting rod 6 is flush with the upper surface of the second tray 72. The head end of the supporting rod 6 is also provided with a bundling hole 5 perpendicular to the rotation plane of the supporting rod 6, which is convenient for the folding and recycling of this embodiment.

[0052] When this embodiment is not in use, it appears as Figure 4 In the folded state shown, the head ends of all the supporting rods 6 are in contact with the suspension rods 4, and the tie bands pass through the binding holes 5 of all the supporting rods 6 to fix the supporting rods 6. When the grating plate needs to be stored and hoisted, first move the embodiment to the side of the grating plate to be stored, untie the tie bands on the binding holes 5, and make the embodiment appear as shown. Figure 6In the unfolded state shown, the upper surface of all the supporting rods 6 is flush with the upper surface of the second tray 72. Then, remove the safety pin at the pin hole 3, the spare cap 2 and the fixing pin at the through hole 14 in turn, and remove the second lifting ring 12. Next, move the grid plate to the top of the suspension rod 4, make the plane of the grid plate parallel to the plane of the second tray 72, align the hole at the center of the grid plate with the suspension rod 4 and insert it so that the grid plate contacts the second tray 72 and the supporting rod 6. Then, according to the above method, place the next grid plate to be stored above the previous grid plate until the storage is completed or the height of the grid plate is not higher than the height of the second lifting ring 12 in the folded state of this embodiment. Finally, place the second lifting ring 12 on the upper end of the suspension rod 4, align the through holes 14, and insert the fixing pin at the through hole 14 so that the second lifting ring 12 and the suspension rod 4 are fixedly connected, tighten the spare cap 2, insert the safety pin into the pin hole 3, operate the lifting device to pull up the second lifting ring 12, and then complete the storage and lifting work of the grid plate.

[0053] When the grating plate is needed, the grating plate together with the present embodiment is placed on the ground by means of a lifting device, the safety pin, the spare cap 2 and the fixing pin at the through hole 14 are removed, the second lifting ring 12 is removed, all the grating plates are moved upward and taken out, and then the second lifting ring 12 is placed on the upper end of the suspension rod 4, the through holes 14 are aligned, and the fixing pin is inserted into the through hole 14 so that the second lifting ring 12 and the suspension rod 4 are fixedly connected, the spare cap 2 is tightened, the safety pin is inserted into the pin hole 3, and finally the head ends of all the supporting rods 6 are in contact with the suspension rod 4, and the supporting rods 6 are fixed by means of cable ties passing through the binding holes 5 of all the supporting rods 6, so that the present embodiment appears as shown. Figure 4 The embodiment can be stored in the folded state shown. It should be noted that the number of the supporting rods 6 in this embodiment is four. Considering the shape of the second tray 72, the need for a good load-bearing capacity when hoisting the grid plate, and the influence of the tool's own weight, the number of the supporting rods 6 is four. In this embodiment, the shape of the second tray 72 is a rectangle, which can be replaced by other shapes, as long as the supporting rods 6 can be evenly distributed on the edge of the second tray 72.
