[0002] A steel grid is a space grid structure formed by steel through specific connection methods (such as welding, bolt connection, etc.). It has a high load-bearing capacity, can bear large loads, provides stable support for buildings or structures, and because the steel grid structure has the performance of multi-directional force transmission, large space stiffness and good integrity, it has excellent seismic performance.

[0003] Steel grids are usually large and heavy, and it is difficult to carry them manually. Therefore, in steel grid construction, hoisting devices such as cranes or hoists are needed to lift and move the steel grid. However, the overall volume of existing hoisting devices is relatively large, and the space required for hoisting the steel grid is often large. If the space of the construction environment is limited, it is not convenient to use large hoisting devices; moreover, in order to prevent the steel grid from falling during hoisting, it is necessary to fix the steel grid. The fixing method of the existing hoisting device for the steel grid is relatively cumbersome, the fixing time is long, and it is laborious to connect the steel grid to the hoisting device.

When the output end of the cylinder is in telescopic operation, it drives the bottom plate to perform telescopic movement, so that the distance between the bottom plate and the top plate is reduced or increased. When the steel grid is placed on the bottom plate, it drives the steel grid to move toward the top plate or away from the top plate. When the steel grid fits the top plate and the bottom plate, the steel grid is fixed between the top plate and the bottom plate, thereby achieving the fixation of the steel grid. Further preferably, each cylinder is fixedly connected to the bottom of the fixed plate, and the output end of each cylinder passes through the fixed plate and is fixedly connected to the bottom plate. More preferably, the output end of each cylinder forms a uniform connection on the bottom plate.

[0020] When the rotating part of the winch rotates, the free end of the hoisting rope moves upward or downward, driving the top plate and the telescopic assembly to move upward or downward. In order to make the movement of the hoisting rope stable, preferably, it also includes a stabilizing component, which includes a first stabilizing plate and a second stabilizing plate; the first stabilizing plate is fixedly connected to the winch, the second stabilizing plate is fixedly connected to the second connecting member, the first stabilizing plate is provided with a first perforation, and the second stabilizing plate is provided with a second perforation.

Further preferably, two rotatable wheels are arranged in the first perforation, and there is a gap between the two wheels, and the hoisting rope can pass through the gap to form a first limiting wheel; similarly, two rotatable wheels are arranged in the second perforation, and there is a gap between the two wheels, and the hoisting rope can pass through the gap to form a second limiting wheel.

One end of the moving plate is fixedly connected to one end of the top plate, one end of the limiting block is fixedly connected to one end of the bottom plate, one end of the round rod is fixedly connected to the bottom of the moving plate, and the other end of the round rod passes through the limiting block and is fixedly connected to the first fixing member of the telescopic assembly. When the telescopic member expands and contracts, it drives the bottom plate to move along the round rod.

[0022] To make the movement of the top plate, bottom plate, moving plate and the first connecting member stable, preferably, a control rod is further included. One end of the control rod is fixedly connected to the rotating table, and the other end passes through the moving plate and the first connecting member. When the spreader moves, the control rod plays a limiting role, and the moving plate and the first connecting member can only move in the length direction of the control rod, so that the bottom plate and the top plate can only move along the length direction of the control rod, making the lifting of the steel frame net stable.

[0023] To facilitate the movement of the steel grid on the top of the bottom plate, a rolling assembly is further included. A groove structure is provided on the top of the bottom plate, and the rolling assembly can be placed in the groove. The rolling assembly includes a sliding plate and a plurality of rollers with the same diameter arranged in parallel on the sliding plate. Each roller corresponds to a fixed shaft on the sliding plate, and one roller rolls around one fixed shaft, and each fixed shaft is parallel to each other. One end of the support member passes through the bottom of the bottom plate and enters the groove, and contacts the bottom of the sliding plate, which can be used to support the sliding plate to raise or lower its position in the groove, so that the surface of each roller is higher than the top of the bottom plate or lower than the top of the bottom plate.

[0024] The support member can be a telescopic member. By its telescoping, the position of the sliding plate in the groove can be adjusted, so as to make the surfaces of the rollers higher than the top of the bottom plate or lower than the top of the bottom plate. The support member can also be non-telescopic. For example, a third fixing member such as a bolt is used to install or remove the support member. During installation, one end of it passes through the bottom of the bottom plate and enters the groove to contact the bottom of the sliding plate and support the sliding plate to raise its position. When the surfaces of the rollers are higher than the top of the bottom plate, the other end of it is fixed to the bottom of the bottom plate by the third fixing member. At this time, when the steel grid frame is placed on the roller surface and moves, the rolling action of the rollers is beneficial to the movement of the steel grid frame. When the steel grid frame does not need to move, the support member can be removed, that is, the third fixing member is removed, and the height of the sliding plate drops until the bottom of the sliding plate contacts the bottom of the groove, and the support member is removed.

[0025] The method for hoisting the steel grid frame by using the hoisting device of the present invention includes one or several of moving, fixing, rotating, and lifting.

[0026] The moving method is as follows: the support member in the rolling assembly supports the sliding plate to raise its position in the groove, so that the surfaces of the rollers are higher than the top of the bottom plate; the steel grid frame is placed on the roller surface, and the steel grid frame moves under the rolling action of multiple rollers; when the movement is completed, the support member in the rolling assembly can be used to lower the position of the sliding plate in the groove, so that the surfaces of the rollers are lower than the top of the bottom plate.

[0027] The fixing method is as follows: the output end of the telescopic member extends and retracts to drive the bottom plate to perform telescopic movement, so that the distance between the bottom plate and the top plate decreases, and the steel grid frame moves towards the top plate until it fits with the top plate, that is, the steel grid frame is clamped and fixed between the top plate and the bottom plate, realizing the fixing of the steel grid frame.

[0028] The rotating method is as follows: the rotating base rotates, driving the lifting member and the lifting tool to rotate, thereby driving the steel grid frame to rotate.

[0029] The lifting method is as follows: the lifting end of the lifting member rises and falls, driving the lifting tool to rise and fall, thereby driving the steel grid frame to rise and fall; and / or, the rotating part of the winch rotates, the free end of the hoisting rope rises and falls, driving the top plate and the telescopic assembly to rise and fall, thereby driving the steel grid frame to rise and fall.

[0030] Preferably, after the steel grid frame is moved to the required position, it is fixed, and then rotated and / or lifted.

[0053] The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention. Those not detailedly described in this technical solution are all well-known technologies.

[0054] As Figure 1-9 shown, the lifting equipment for steel grid construction includes a rotating base 1, a lifting member 2 and a lifting tool 3.

[0055] One end of the lifting member 2 is fixed on the rotating base 1, and the other end is the lifting end. The lifting end is fixedly connected to one end of the first connecting member 20, and the lifting tool 3 is fixedly connected to the other end of the first connecting member 20.

[0056] When the rotating base 1 rotates, it drives the lifting member 2 and the lifting tool 3 to rotate. The lifting end of the lifting member 2 can be lifted and lowered along the direction perpendicular to the rotating surface of the rotating base 1, and drives the lifting tool 3 to be lifted and lowered in the same direction during the lifting and lowering process.

[0057] As Figure 1 . 2As shown in the figure, the sling 3 includes a winch 301, a hoisting rope 302, a top plate 303, a bottom plate 307 and a telescopic assembly. The winch 301 is fixed on the first connecting member 20. The winch 301 includes a rotating member 308. One end of the hoisting rope 302 is fixed on the rotating member 308, and the other end is a free end. This free end is wound around the rotating member 308 and its end is fixedly connected to the top plate 303.

[0058] As Figure 6 described, the telescopic assembly includes a first fixing member 401 and a telescopic member 402. One end of the telescopic member 402 is fixedly connected to the first fixing member 401, and the other end is a telescopic end. The end of the telescopic end is fixedly connected to the bottom plate 307.

[0059] One end of the top plate 303 is fixedly connected to one end of the second connecting member, and the other end is fixedly connected to the first fixing member 401. There is a gap between the top plate 303 and the bottom plate 307. When the telescopic end of the telescopic member 402 expands and contracts, it drives the bottom plate 307 to move, causing the gap to decrease or increase.

[0060] In this embodiment, as Figure 1 、 3 shown in FIGS. 3 and 4, the rotating base 1 includes a first support base 101, a rotating motor 103, a fixing frame 102 and a rotating table 104. The fixing frame 102 is fixed on the first support base 101. The rotating motor 103 is fixed on the fixing frame 102. The rotating output end of the rotating motor 103 is fixedly connected to the rotating table 104. When the rotating output end of the rotating motor 103 rotates, it drives the rotating table 104 to rotate. In this embodiment, the rotating motor 103 is located below the fixing frame 102, and its rotating output end passes through the fixing frame 102 and is fixedly connected to the bottom of the rotating table 103.

[0061] In order to improve the rotation stability of the rotating table 104, in this embodiment, a second support base 8 is provided between the first support base 101 and the rotating table 104. In this embodiment, the second support base 8 has a hollow structure with both ends open. One end opening is in a circular ring structure, and the other end opening is fixedly connected to the bottom of the rotating table 104. A groove is provided on the surface of the first support base 101. This circular ring structure can be embedded in this groove to form a movable connection with the first support base 101. When the rotating table 104 rotates, it drives this circular ring structure to rotate in this groove. In order to improve the rotation smoothness of the rotating table 104, in this embodiment, the bottom of this circular ring structure is movably connected to a plurality of balls 12, and they are evenly distributed. The surfaces of the balls 12 are all movably connected to the bottom of this groove. Through the movable connection between the plurality of balls and the groove, the rotation effect of the circular ring structure is improved, thereby improving the rotation smoothness of the rotating table 104.

[0062] In order to further improve the support stability of the first support base 101 and prevent the first support base 101 from sliding, in this embodiment, the rotating base 1 further includes a plurality of protection blocks 9, and the protection blocks 9 are fixedly distributed around the first support base 101 to limit the first support base 101 and make the rotation of the rotating platform 104 driven by the rotation output end of the rotation motor 103 more stable.

[0063] In order to further improve the support stability of the first support base 101, preferably, each protection block 9 is fixedly connected to a limit assembly for strengthening the protection block and restricting the swaying of the protection block. In this embodiment, the limit assembly is composed of a plurality of limit blocks 10 and second fixing members 11. Each limit block 10 is provided with a second fixing member 11. Threads are provided on the surfaces of the second fixing members 11. One end of each second fixing member 11 is threaded through a limit block 10, and the other end is screwed into the ground. Rotate the second fixing member 11 to move it towards the ground until it is tightened and immovable, increasing the fixing effect with the ground.

[0064] In this embodiment, the lifting member 2 is an electric telescopic column.

[0065] In this embodiment, the first fixing member in the telescopic assembly is a fixing plate, and the telescopic members are a plurality of cylinders. Each cylinder is fixedly connected to the fixing plate. The output ends of the cylinders are telescopic ends, and each telescopic end is fixedly connected to the bottom plate 307. When the output ends of the cylinders perform telescopic operation, the bottom plate 307 is driven to perform telescopic movement, so that the distance between the bottom plate 307 and the top plate 303 is reduced or increased. When the steel grid is placed on the bottom plate 307, it drives the steel grid to move towards or away from the top plate 303. When the steel grid is in contact with both the top plate 303 and the bottom plate 307, the steel grid is fixed between the top plate 303 and the bottom plate 307, realizing the fixation of the steel grid.

[0066] In this embodiment, each cylinder is fixedly connected to the bottom of the fixing plate, and the output ends of the cylinders pass through the fixing plate and are fixedly connected to the bottom plate 307. In this embodiment, the output ends of the cylinders are evenly connected on the bottom plate 307.

[0067] In this embodiment, when the rotating member 308 of the winch 302 rotates, the free end of the hoisting rope 302 moves upward or downward, driving the top plate 303 and the telescopic assembly to move upward or downward.

[0068] In order to make the movement of the hoisting rope 302 stable, in this embodiment, a stabilizing assembly is further included, such as Figure 2 、 7As shown, the stabilizing component includes a first stabilizing plate 501 and a second stabilizing plate 502. The first stabilizing plate 501 is fixedly connected to the winch 301, and the second stabilizing plate 502 is fixedly connected to the second connecting piece. The first stabilizing plate 501 is provided with a first through hole, and the second stabilizing plate 502 is provided with a second through hole. The free end of the hoisting rope 302 passes through the first through hole and the second through hole and is fixedly connected to the top plate 303. That is, the first through hole and the second through hole realize the limitation of the hoisting rope.

[0069] In this embodiment, preferably, two rotatable wheels are arranged in the first through hole, and there is a gap between the two wheels. The hoisting rope can pass through the gap to form a first limiting wheel member 503. Similarly, two rotatable wheels are arranged in the second through hole, and there is a gap between the two wheels. The hoisting rope can pass through the gap to form a second limiting wheel member 504. The hoisting rope 302 can only move up and down inside the two limiting wheel members, thereby limiting the hoisting rope 302 and preventing the hoisting rope 302 from shaking during the up and down movement.

[0070] In this embodiment, as Figure 2 , 5 , as shown in Figure 6, the second connecting piece includes a moving plate 304, a round rod 305 and a limiting block 306. One end of the moving plate 304 is fixedly connected to one end of the top plate 303, one end of the limiting block 306 is fixedly connected to one end of the bottom plate 307, one end of the round rod 305 is fixedly connected to the bottom of the moving plate 305, and the other end of the round rod 305 passes through the limiting block 306 and is fixedly connected to the first fixing member 401 of the telescopic component. When the telescopic member 402 expands and contracts, it drives the bottom plate 307 to move along the round rod 305. That is, the bottom plate 307 can only move along the length direction of the round rod 305 through the cooperation of the limiting block 306 and the round rod 305. In this structure, the second stabilizing plate 504 is preferably L-shaped, with a second limiting wheel member 504 arranged at one end of its long side and the top of the moving plate 304 fixedly connected to the other end of its short side.

[0071] In this embodiment, preferably, the limiting block 306 is arranged in two pieces, namely the first limiting block and the second limiting block, and the round rod 305 is arranged in two pieces, namely the first round rod and the second round rod. One end of the first limiting block is fixedly connected to one end of the bottom plate 307, one end of the second limiting block is fixedly connected to one end of the bottom plate 307, one end of the first round rod is fixedly connected to the bottom of the moving plate 304, and the other end passes through the first limiting block and is fixedly connected to the first fixing member 401. One end of the second round rod is fixedly connected to the bottom of the moving plate 304, and the other end passes through the second limiting block and is fixedly connected to the first fixing member 401.

[0072] To make the top plate 303, the bottom plate 307, the moving plate 304 and the first connecting piece 20 move stably, as Figure 1As shown, in this embodiment, preferably, a control rod 7 is further included. One end of the control rod 7 is fixedly connected to the rotating table 104, and the other end passes through the moving plate 304 and is connected to the first connecting member 20. When the lifting device 3 moves up and down, the control rod 7 plays a limiting role, and the moving plate 304 and the first connecting member 20 can only move in the length direction of the control rod 7, so that the bottom plate 307 and the top plate 303 can only move along the length direction of the control rod 7, thereby making the lifting of the steel frame net stable.

[0073] To facilitate the movement of the steel grid on the top of the bottom plate 307, a rolling assembly 6 is further included. As Figure 5 、 8 、9 show, a groove structure is provided on the top of the bottom plate 307, and the rolling assembly can be placed in the groove. The rolling assembly includes a sliding plate 602 and a plurality of rollers 601 with the same diameter arranged in parallel on the sliding plate; each roller 601 corresponds to a fixed shaft 604 one by one, and one roller rolls around a fixed shaft 604, and the fixed shafts 604 are parallel to each other; one end of the support member 603 passes through the bottom of the bottom plate 307 and enters the groove, and contacts the bottom of the sliding plate 602, and can be used to support the sliding plate 602 to raise or lower its position in the groove, so that the surface of each roller 601 is higher than the top of the bottom plate 307 or lower than the top of the bottom plate 307.

[0074] The support member 603 can be a telescopic member, and the position of the sliding plate 602 in the groove can be adjusted by its telescoping, so as to achieve that the surface of each roller 601 is higher than the top of the bottom plate 307 or lower than the top of the bottom plate 307. In this embodiment, the support member 603 does not have telescopic properties, and a third fixing member 605 such as a bolt is used to install or remove the support member 603; during installation, one end of it passes through the bottom of the bottom plate 307 and enters the groove to contact the bottom of the sliding plate 602 and support the sliding plate 602 to raise its position. When the surface of each roller 601 is higher than the top of the bottom plate 307, the other end of it is fixed to the bottom of the bottom plate 307 by the third fixing member 605. At this time, when the steel grid is placed on the surface of the roller 601 and moves, the rolling action of the roller 601 is beneficial to the movement of the steel grid; when the steel grid does not need to move, the support member 603 can be removed, that is, the third fixing member 605 is removed, and the height of the sliding plate 602 drops until the bottom of the sliding plate contacts the bottom of the groove, and the support member 603 is removed.

[0075] During construction, when using this hoisting device to hoist the steel grid, the operations include the movement, fixation, rotation and lifting of the steel grid.

[0076] The method of moving is as follows: The supporting member 603 in the rolling component supports the sliding plate 602, raising its position in the groove so that the surfaces of the rollers 601 are higher than the top of the bottom plate 307; then, place the steel grid frame on the surfaces of the rollers 601 and move the steel grid frame under the rolling action of the multiple rollers 601; when the movement is completed, the supporting member 603 in the rolling component can be used to lower the sliding plate 602 at the position of the groove, so that the surfaces of the rollers 601 are lower than the top of the bottom plate 307. In this embodiment, by removing the third fixing member 605 and removing the supporting member 603, the height of the sliding plate 602 drops until the bottom of the sliding plate 602 falls back to contact the bottom of the groove.

[0077] The method of fixing is as follows: The output end of the telescopic member performs telescopic operation, driving the bottom plate 307 to perform telescopic movement, reducing the distance between the bottom plate 307 and the top plate 303, and moving the steel grid frame towards the top plate 303 until it fits against the top plate 303, that is, the steel grid frame is clamped and fixed between the top plate 303 and the bottom plate 307, achieving the fixing of the steel grid frame.

[0078] The method of rotating is as follows: Rotate the base 1, driving the lifting member 2 and the lifting tool 3 to rotate, thereby driving the steel grid frame to rotate.

[0079] The method of lifting is as follows: The lifting end of the lifting member 2 lifts and lowers, driving the lifting tool 3 to lift and lower, thereby driving the steel grid frame to lift and lower; and / or, the rotating part 308 of the winch 301 rotates, and the free end of the hoisting rope 302 lifts and lowers, driving the top plate 303 and the telescopic component to lift and lower, thereby driving the steel grid frame to lift and lower.

[0080] During construction, generally, the steel grid frame is moved to the required position and then fixed, and then rotated and / or lifted.
