[0056] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0057] Demoulding is an important and indispensable step in the production of the hollow slab 10. The existing method is to use a crowbar to move the cut hollow slab 10 to a sufficiently wide interval, and use a sling to pass through the bottom of the hollow slab 10 on both sides to fix it and then lift it. However, using a sling to pass through the bottom of the hollow slab 10 on both sides cannot lift it into place at one time, which affects production efficiency.

[0058] In view of this, if Figure 1-7 As shown, it should be noted that in order to better understand the structure, Figure 5 and Figure 6 Only the lower half structure is shown, and the upper half structure can be seen in other drawings.

[0059] The hollow plate horizontal lifting tool provided in this embodiment includes two symmetrically arranged lifting devices; the lifting device includes a fixing component 100, a force-bearing component 200, a force-transmitting component 300 and a clamping handle 400; the fixing component 100 is arranged horizontally, and the clamping handle 400 is rotatably connected to the fixing component 100; the force-bearing component 200 has a rotating shaft 210 rotatably connected to the fixing component 100, and a lifting ring 211 for connecting to the lifting device is arranged on the rotating shaft 210, and the rotating shaft 210 is configured to be able to receive the pulling force of the lifting device so that the rotating shaft 210 rotates along its own axis direction; The force-bearing component 200 has a force rod 220 that can move relative to the fixed component 100. The force rod 220 and the rotating shaft 210 are arranged perpendicular to each other, and the rotating shaft 210 is connected to the force rod 220 so that the rotation of the rotating shaft 210 drives the force rod 220 to move; the force transmission component 300 has a force guiding rod 310, one end of the force guiding rod 310 is connected to the force rod 220, and the other end of the force guiding rod 310 is connected to the clamping grabber 400. The force guiding rod 310 is configured to be able to drive the clamping grabber 400 to rotate with the movement of the force rod 220, so that the clamping grabber 400 clamps the hollow plate 10.

[0060] Specifically, two lifting devices are provided, and the structures of the two lifting devices are the same. The two lifting devices are symmetrically arranged along the lifting equipment, so that the two lifting devices are respectively located on both sides below the lifting equipment, and the two lifting devices are connected by an adjusting rod 500. Both ends of the adjusting rod 500 have threaded sections, and the threaded sections at both ends of the adjusting rod 500 are respectively threadedly connected with the focusing rods 110 in the two lifting devices. By screwing the adjusting rod 500, the focusing rods 110 located on the same straight line can be adjusted to be closer or farther away from each other, and the distance between the two lifting devices as a whole can be adjusted, which is suitable for lifting hollow slabs 10 of different lengths.

[0061] The hollow slab horizontal lifting tool provided in the present embodiment connects the lifting device to the rotating shaft 210 through the lifting rings 211 distributed on both sides below the lifting device. The hook of the lifting device is located on the middle axis of the two lifting devices. When the lifting device is lifted upward, the pulling force generated by the lifting device causes the rotating shafts 210 on both sides to rotate along their own axis directions toward the lifting device. The rotation of the rotating shaft 210 drives the force rod 220 to move. The movement of the force rod 220 drives the end of the force guide rod 310 to move, and then the other end of the force guide rod 310 drives the clamping handle 400 to rotate in the direction close to the hollow slab 10. By clamping the hollow slab 10, the hollow slab 10 can be lifted horizontally and can be hoisted into place at one time without using a lifting rope or a lifting belt to pass through the hollow slab 10. This alleviates the technical problem in the prior art that the lifting belt passes through the bottom of the hollow slab 10 on both sides and cannot be hoisted into place at one time, thereby affecting production efficiency.

[0062] It should be noted that, since the hollow slab horizontal lifting tool includes two lifting devices with the same structure, the subsequent description only describes the structure and shape of one of the lifting devices, and the other lifting device is symmetrically arranged with the lifting device.

[0063] Regarding the structure and shape of the fixing assembly 100, specifically:

[0064] The fixing assembly 100 includes a focusing rod 110, a connecting rod 120, a connecting bolt 130, a lifting point focusing plate 140 and a retaining spring 150. Two focusing rods 110 are arranged in parallel and spaced apart, and four connecting rods 120 are arranged between the two focusing rods 110. Both ends of the connecting rod 120 have sleeves, which are sleeved on the focusing rod 110. The connecting bolt 130 passes through the sleeve on the connecting rod 120 and extends into the focusing rod 110, so that the connecting rod 120 can be fixed on the focusing rod 110.

[0065] The four connecting rods 120 are respectively recorded as the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod from left to right. The clamping handle 400 is installed on the focusing rod 110 between the first connecting rod and the second connecting rod, the clamping handle 400 is installed on the focusing rod 110 between the third connecting rod and the fourth connecting rod, and the lifting point focusing plate 140 is installed on the focusing rod 110 between the second connecting rod and the third connecting rod, and a lifting point focusing plate 140 is provided on each focusing rod 110. The lifting point focusing plate 140 has a rotating hole, one end of one rotating shaft 210 passes through the rotating hole on the lifting point focusing plate 140, so that the rotating shaft 210 can rotate in the rotating hole along its own axis direction, and the other end of the rotating shaft 210 is connected to the fixed sleeve 280, one end of the other rotating shaft 210 is rotatably connected to another lifting point focusing plate 140, and the other end is connected to the fixed sleeve 280.

[0066] A slot is provided on the focusing rod 110 between the first connecting rod and the second connecting rod, and two retaining springs 150 are installed in the slot. The two retaining springs 150 are respectively located at the two ends of the clamping bag 400. The setting of the two retaining springs 150 limits the position of the clamping bag 400 to prevent the clamping bag 400 from moving left and right along the focusing rod 110.

[0067] Regarding the structure and shape of the force bearing component 200, specifically:

[0068] The force-bearing component 200 includes a rotating shaft 210, a lifting ring 211, a force rod 220, a force guide key 230, a tube pillow 240, a pillow bed 250, a stabilizing key 260, a stabilizing screw 270, and a fixed sleeve 280; two rotating shafts 210 are provided, and the two rotating shafts 210 are arranged in the same straight line. The two rotating shafts 210 are fixedly connected by a fixed sleeve 280, and the ends of the rotating shafts 210 can be welded to the fixed sleeve 280 so that the two rotating shafts 210 rotate synchronously.

[0069] A lifting ring 211 is installed on the top of each rotating shaft 210. The lifting ring 211 is used to connect with an external lifting device. The lifting ring 211 is welded and fixed on the rotating shaft 210. When the lifting device lifts upward, the lifting device generates an oblique upward pulling force on the lifting ring 211, driving the rotating shaft 210 to rotate. In addition, a handle is installed at the end of the rotating shaft 210. The handle is perpendicular to the rotating shaft 210 in the vertical direction, which is convenient for manual grip of the handle to drive the rotating shaft 210 to rotate.

[0070] A force rod 220 is arranged below the rotating shaft 210, and the axis of the force rod 220 is perpendicular to the axis of the rotating shaft 210. A force guiding groove 221 is opened on the top of the force rod 220, and the force guiding key 230 passes through the rotating shaft 210 and extends into the force guiding groove 221. During the rotation of the rotating shaft 210, the force guiding key 230 rotates together with the rotating shaft 210, so that the force guiding key 230 drives the force rod 220 to move left and right.

[0071] A pillow bed 250 is provided on the top of each connecting rod 120 , and a tube pillow 240 is installed on the pillow bed 250 . The force rod 220 passes through four tube pillows 240 to support the force rod 220 and limit the moving direction of the force rod 220 .

[0072] A stabilizing groove is opened at the top of the tube pillow 240 on the second connecting rod and the fourth connecting rod, and the stabilizing key 260 is installed in the stabilizing groove, and the stabilizing key 260 is fixed in the stabilizing groove by a stabilizing screw 270. The function of the stabilizing key 260 is to control the correct direction of the force rod 220 to avoid deflection caused by force.

[0073] The fixing sleeve 280 is fixedly mounted on the two rotating shafts 210 located on the same straight line, so that the two rotating shafts 210 rotate synchronously.

[0074] Regarding the structure and shape of the force transmission component 300, specifically:

[0075] The force transmission assembly 300 includes a force guiding rod 310, a force receiving end 320, an inner stopper 330, an outer stopper 340 and a force transmission shaft 350; a through hole 222 is opened on the force giving rod 220, one end of the force guiding rod 310 extends into the through hole 222, and the force transmission shaft 350 passes through the force giving rod 220 and extends into the through hole 222 to be connected with the end of the force guiding rod 310, so that the end of the force guiding rod 310 can rotate around the force transmission shaft 350.

[0076] A force-bearing end 320 is connected to the top of the clamping copyboard 400, and the other end of the force-guiding rod 310 is opened and sleeved on the force-bearing end 320, so that the force-guiding rod 310 can rotate around the force-bearing end 320. In order to prevent the end of the force-guiding rod 310 from falling off the force-bearing end 320, an inner stopper 330 and an outer stopper 340 are threadedly connected to the force-bearing end 320, and the inner stopper 330 is located below the outer stopper 340. The end of the force-guiding rod 310 is clamped in the middle by the inner stopper 330 and the outer stopper 340, so as to effectively prevent the force-guiding rod 310 from falling off.

[0077] It should be noted that in a stationary state, there is an angle between the force-guiding rod 310 and the force-giving rod 220, and the force-guiding rod 310 is oriented closer to the lifting device. During the lifting process, the rotation of the rotating shaft 210 drives the force-giving rod 220 to move horizontally in a direction away from the lifting device, and the end of the force-guiding rod 310 moves together with the force-giving rod 220. The end of the force-guiding rod 310 drives the force-receiving end 320 to rotate outward, and then the force-receiving end 320 drives the clamping handle 400 to rotate inward, thereby clamping the hollow plate 10.

[0078] Regarding the structure and shape of the clamping spoon 400, specifically:

[0079] The clamping handle 400 is an important component for clamping the hollow plate 10 in the lifting tool. The clamping handle 400 includes a cylindrical end 410 and a clamping end 420. The cylindrical end 410 is sleeved on the force rod 110, and the force end 320 is fixedly connected to the cylindrical end 410. The clamping end 420 is connected below the cylindrical end 410. The clamping end 420 has a latching tooth. When the force end 320 is forced to rotate outward, the rotation of the cylindrical end 410 drives the clamping end 420 to rotate inward, so that the clamping end 420 clamps the hollow plate 10.

[0080] The hollow plate 10 provided in this embodiment is lifted horizontally as a tool. The lifting principle is as follows: after all components are assembled, they are placed at the length center of the hollow plate 10. Two groups of eight clamping handles 400 are extended naturally perpendicular to both sides of the hollow plate 10. At this time, the lifting rope of the lifting equipment is connected to the lifting ring 211. After receiving force, it rotates centripetally to drive the rotating shaft 210 to rotate. The force guide key 230 simultaneously toggles the force guide groove 221 to drive the force rod 220 to extend outward. The force guide rod 310 centered on the force rod 220 extends outward to push the force receiving end 320 rotates outwardly with the force rod 110 as the center, and the clamping handle 400 corresponding to the force-bearing end 320 rotates inwardly and communicates with the outer side of the hollow plate 10 to form a combined force to complete the lifting; after the hollow plate 10 is hoisted into place, it is necessary to manually pull the handle to drive the rotating shaft 210 to rotate and disengage from the component to complete the lifting of a hollow plate 10, so that the hollow plate 10 can be lifted horizontally without passing the lifting rope through the bottom of the plate to be lifted to the designed position at one time, and the tool length can be adjusted according to the length of the hollow plate 10 using the adjusting rod 500.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
