[0017] See also Figure 1 to Figure 2 , which shows the preferred structure of the safe hoisting device for hoisting bricks in construction provided by the embodiment of the present invention. As shown in the figure, the safe hoisting device includes: a bottom support 1 and a hoisting cage 2.

[0018] The base 1 is used for supporting the bottom of the bricks; the lifting cage 2 is covered on the top of the base 1, and the lifting cage 2 is connected to the base 1 in a detachable manner, and is used to be covered outside the bricks before the bricks are stacked and transported, so as to realize the lifting of the bricks.

[0019] Specifically, the base 1 can be a fixed base, and stacked bricks can be stacked on the base 1, so that the lifting of multiple bricks on the base 1 can be completed by the lifting of the lifting device. Of course, in other embodiments, the base 1 can also be a mobile base, and the mobile base 1 has a walking state and a fixed support state. In the walking state, the mobile base 1 moves to change the construction position so as to move to the location of the bricks. In the fixed support state, the mobile base 1 is fixedly supported to stably stack the bricks. The lifting cage 2 can be covered on the base 1, and the two can be detachably connected to form a rectangular structure with an open top, and can also be surrounded to form a rectangular structure with both ends sealed. Among them, the bricks can be various types of block bricks such as sintered bricks 240mm×115mm×53mm, autoclaved concrete blocks 600mm×200mm / 250mm×75mm / 100mm / 150mm, etc. In this embodiment, a lifting ring 3 is provided on the top of the lifting cage 2 .

[0020] In one implementation of this embodiment, Figures 3 to 6 As shown, the base bracket 1 is a fixed base bracket, which includes: a support plate 11, a reinforcement rod 12 and an insertion rod 13.

[0021] The reinforcement rod 12 is arranged below the support plate 11, and the reinforcement rod 12 is connected to the support plate 11 for reinforcing the support plate 11; the insertion rod 13 is arranged below the reinforcement rod 12, and the insertion rod 13 is arranged at an angle to the reinforcement rod 12 and is connected to the reinforcement rod 12 for detachable connection with the hoisting cage 2.

[0022] Specifically, the support plate 11 as the first layer can be a steel plate structure, which can be a steel plate with a length × width of 1300mm × 1300mm and a thickness of 5mm. The reinforcement rod 12 can be connected to the support plate 11 by welding to reinforce the bearing capacity of the steel plate, wherein the reinforcement rod 12 as the second layer can be a square steel with a length × width × height of 1300mm × 50mm × 30mm and a thickness of 3mm, which is horizontally welded below the support plate 11. There are multiple reinforcement rods 12, which are arranged side by side and at intervals along the length direction of the support plate. The insertion rod 13 can be arranged below the reinforcement rod 12, and the insertion rod 13 is arranged at an angle with the reinforcement rod 12 and connected, so as to realize the connection between the base 1 and the hoisting cage 2. In this embodiment, the insertion rod 13 is a rod structure with a hollow interior, and a socket rod 14 is inserted therein. The two ends of the socket rod 14 are convexly arranged at the two ends of the insertion rod 13. The bottom of the hoisting cage 2 is provided with an insertion hole, and the two ends of the socket rod 14 are inserted into the insertion hole of the hoisting cage 2. Among them, two square steels with a length × width × height of 1300mm × 80mm × 50mm and a thickness of 5mm can be welded on both sides of the vertical center point of the third layer under the 7 square steels as the base and the insertion hole of the hoisting cage fixed by the socket rod. Among them, the socket rod 14 is a hollow steel pipe with a diameter of 38mm, a length of 1700mm, and a thickness of 5mm.

[0023] In another implementation of this embodiment, see Figure 7 The movable base 1 comprises: a base body 15, a moving part 16, and a telescopic leg 17; wherein, The base body 15 plays a supporting role. Specifically, the structure of the base body 15 can refer to the structure of the fixed base in the previous embodiment.

[0024] The moving part 16 is arranged at the bottom of the base body 15 (relative to the Figure 7 The movable part 16 is used to drive the bottom support body 15 to move, so as to drive the whole device to move. Specifically, there can be multiple movable parts 16, which are located at the four corners of the bottom of the bottom support body 15 to provide multiple walking support points, thereby ensuring the stability of the movement of the device. Among them, one or more of the movable parts 16 can be used as a driving wheel to drive the chassis 1 to move.

[0025] The telescopic legs 17 are rotatably connected to the bottom support body 15; in the fixed support state, the telescopic legs 17 are rotated to a vertical position (relative to the Figure 7 The telescopic legs 17 are rotatably connected to the base body 15 through an articulated plate to realize the rotation of the telescopic legs 17, thereby realizing the conversion of the telescopic legs 17 between the vertical position and the folded position; wherein the articulated plate may be a universal articulated plate to drive the telescopic legs 17 to rotate 360°. In the present embodiment, there may be four telescopic legs 17 to ensure the stability of the fixed support of the base body 15.

[0026] Of course, the telescopic legs 17 can also be directly vertically arranged and fixedly connected to the base body 15, so as to achieve the switching of the telescopic legs 17 being suspended in the air or the moving part 16 being suspended in the air only by telescopic adjustment, that is, the telescopic legs 17 are arranged on the base body 15, and in the fixed support state, the telescopic legs 17 are telescopically adjusted to contact the support surface, so that the moving part 16 is suspended in the air, so as to perform fixed support through the telescopic legs 17; in the walking state, the telescopic legs 17 are telescopically adjusted to the suspended state, and the moving part 16 contacts the support surface, so as to perform walking and moving support through the moving part 16.

[0027] In this embodiment, the telescopic legs 17 are rotatably connected to the base body 15, and in particular, the structure of the rotatable connection and the telescopic legs 17 can realize the switching of the two states of the base during movement; at the same time, in the fixed support state, it can be rotated to a horizontal position or other direction position for folding, which can avoid interference or collision between the telescopic legs 17 and other objects when the sorting device moves; in the walking state, it can be rotated to a vertical position, and then through telescopic adjustment, the bottom of the telescopic legs 17 can contact the support surface and gradually lift the base body 15, so that the lifting device as a whole is supported by the telescopic legs 17, and the moving part 16 is suspended in the air, and it can be switched to the fixed support state.

[0028] See also Figure 8 , which is a structural block diagram of a mobile base provided by an embodiment of the present invention. As shown in the figure, the mobile base also includes: a moving part state sensor 100, a leg state sensor 200 and a controller 300; wherein, The moving part state sensor 100 is used to detect whether the moving part is in a suspended state, and can send a moving part state signal of the moving part 16 to the controller 300. Specifically, the moving part state sensor 100 can be a pressure sensor, which can be arranged on the moving part 16, and is used to detect the pressure on the moving part 16 to detect whether the moving part 16 is in a suspended state. For example, when the pressure on the moving part 16 is zero, the moving part 16 is in a suspended state, otherwise the moving part 16 is not in a suspended state, and the moving part state signal of the moving part 16 can be sent to the controller 300. Of course, the moving part state sensor 100 can also be other sensors to detect whether the moving part 16 is in a suspended state.

[0029] The leg state sensor 200 is used to detect whether the telescopic leg 17 is in a suspended state, and send the leg state signal of the telescopic leg 17 to the controller 300. Specifically, the leg state sensor 200 can determine the state of the movable base 1 by detecting whether the telescopic leg 17 is in a suspended state, and combining the moving part state signal of the moving part 16, that is, when the telescopic leg 17 is in a suspended state and the moving part 16 is not in a suspended state, the movable base 1 is in a walking state, and the moving part 16 can drive the sorting device to move as a whole; when the telescopic leg 17 is not in a suspended state and the moving part 16 is in a suspended state, the movable base 1 is in a fixed support state.

[0030] The controller 300 is connected to the moving part state sensor 100 and the leg state sensor 200 respectively, and is used for receiving the moving part state signal emitted by the moving part state sensor 100 and the leg state signal emitted by the leg state sensor 200, and controlling the rotation and extension of the telescopic legs 17 according to the moving part state signal and the leg state signal, so as to realize the switching of the state of the mobile base support 1, that is, when it is necessary to move to the working position, the telescopic legs 17 are retracted and rotated to the folded position so that the moving part 16 contacts the support surface; when it is necessary to stack bricks, the telescopic legs 17 are rotated to a vertical position and extended to contact the support surface, and the base support body 15 is gradually lifted so that the moving part 16 is suspended, and after fixed support by the telescopic legs 17, bricks are stacked, etc.

[0031] See also Fig. 9, which is a structural block diagram of the leg state sensor provided by an embodiment of the present invention. As shown in the figure, the leg state sensor 200 may include: a rotation direction sensor 210, a length sensor 220 and a leg state judgment unit 230; wherein the rotation direction sensor 210 is used to detect the direction of the current rotation position of the telescopic leg 17, so as to detect whether the telescopic leg 17 is in a vertical position or a folded position; the length sensor 220 is used to detect the length of the telescopic leg 17, so as to detect whether the length of the telescopic leg 17 is extended to a preset support length or retracted to a preset suspended length; the leg state judgment unit 230 is connected to the rotation direction sensor 210 and the length sensor 220 respectively, and is used to analyze and judge whether the telescopic leg 17 is in a suspended state according to the direction of the current rotation position of the telescopic leg 17 detected by the rotation direction sensor 210 and the length of the telescopic leg 17. Specifically, the rotation direction sensor 210 can be set on the bottom support body 15, and detect the direction of the current rotation position of the telescopic leg 17 by detecting the position of the hinge plate; of course, the direction of the current rotation position of the telescopic leg 17 can also be directly detected, and this is not limited in this embodiment. The length sensor 220 detects the length of the telescopic leg 17 itself, and the leg state judgment unit 230 analyzes and judges whether the telescopic leg 17 is in a suspended state based on the direction of the current rotation position of the telescopic leg 17 detected by the rotation direction sensor and the length of the telescopic leg 17, that is, when the telescopic leg 17 is in a vertical position, the bottom end of the telescopic leg 17 (relative to the vertical position) can be judged based on the length of the telescopic leg 17. Figure 2 The distance between the movable part 16 and the bottom bracket body 15 can be determined by comparing the distance between the movable part 16 and the bottom bracket body 15, thereby driving the telescopic legs 17 to determine whether they are in a suspended state. It can also be determined whether the movable part 16 is in a suspended state based on this, so as to determine the state of the chassis 1 during the movement. Among them, the preset support length and the preset suspension length can be determined according to actual conditions, as long as the length of the telescopic legs 17 is the preset support length and in a vertical position, the bottom end of the telescopic legs 17 contacts the support surface, and the movable part 16 is suspended at the same time; similarly, when the length of the telescopic legs 17 is the preset suspension length and in a vertical position, the telescopic legs 17 are suspended and the movable part 16 contacts the support surface at the same time.

[0032] Continue to see Figure 1The hoisting cage 2 may include a hoisting frame 21 and a disassembly fixture 22 arranged on the hoisting frame 21; wherein the disassembly fixture 22 is arranged at the bottom of the hoisting frame 21, and is used to be detachably connected to the bottom bracket 1, and can be disassembled and connected through the socket stick 14. wherein, an anti-slip net 23 is arranged on the hoisting frame 21, and the anti-slip net 23 can be a wire mesh, and the hoisting frame 21 can be welded by multiple angle steels, such as 8 angle steels, and the disassembly fixture 22 can be a flat steel with an insertion hole arranged thereon, and the anti-slip net 23 is arranged on the four hollowed-out parts of the hoisting frame 21, the angle steel has a width of 50mm, a length of 1500mm, and a thickness of 5mm, and the flat steel has a width of 100mm, a length of 1500mm, and a thickness of 5mm with an insertion port corresponding to the third layer of square steel of the bottom bracket, and hoisting circular rings are welded at the four corners of the top of the hoisting cage 2 as hoisting rings 3, and wire mesh sheets are arranged at other hollowed-out positions as anti-slip nets 23.

[0033] The method of using the safe lifting device is as follows: various bricks need to be neatly stacked on the base 1, and the lifting cage 2 is buckled on. The socket stick 14 is inserted into the insertion rod 13 of the base 1 to fix it, and then the lifting tools such as wire rope are connected to the lifting point of the lifting cage 2 for lifting. This can greatly prevent the bricks from scattering during the lifting process, and is safer.

[0034] In summary, the safe lifting device for lifting bricks in construction provided by the present embodiment is easy to use, easy to operate, and highly safe. It can effectively prevent accidents such as brick scattering, and can be better used in brick lifting construction. It is beneficial to the protection of other workers on the ground, improves the safety of lifting bricks, prevents object impacts and lifting accidents, further reduces the occurrence of safety accidents, and solves the problem that the existing brick lifting process is prone to cause brick stacks to scatter, causing property losses and even casualties.
