[0002] Modern construction projects often involve complex and changeable building structures, such as large-span factories and high-rise buildings. Therefore, it is necessary to adjust the lifting angle and height of building materials to meet construction needs of different dimensions. In order to meet the above needs, intelligent hoists can be used to hoist materials. Intelligent hoists integrate advanced sensors, control systems and drive technologies to achieve precise control of the hoisting process. It can automatically adjust the hoisting angle and height according to the specific needs of the construction site to ensure that building materials can accurately reach the predetermined position.

The user passes the placement plate through the inside of the material lifting ring and limits the material lifting ring through the baffle to realize the lifting operation of the material.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a multi-dimensional intelligent lifting equipment for construction engineering. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] like Figure 1-Figure 3 As shown, the present invention provides: a multi-dimensional intelligent lifting equipment for construction engineering, comprising a column 1, a cross bar 2 is fixedly connected to the upper surface of the column 1, one end of the cross bar 2 is rotatably connected to a support rod 3, one end of the support rod 3 is fixedly connected to a hoist 4, one end of the hoist 4 is fixedly connected to a control handle 41, the lower surface of the control handle 41 is rotatably connected to a connecting frame 5, and the lower surface of the connecting frame 5 is provided with a sling mechanism;

[0046] The sling mechanism includes a fixed frame 6 fixedly connected to the lower surface of the connecting frame 5, the inner wall of the fixed frame 6 is symmetrically slidably connected with a moving block 64, the lower surface of the moving block 64 is rotatably connected with a rotating frame 7, the interior of the rotating frame 7 is rotatably connected with a placement plate 71, and the upper surface of the rotating frame 7 and located on the upper surface of the placement plate 71 is rotatably connected with a baffle 73.

[0047] Specifically, the hoisting mechanism of the prior art generally uses a single hook to hoist the building materials. When the building materials need to be hoisted, the materials with the hoisting ring are passed through the hook to complete the hoisting. When the materials without the hoisting ring need to be hoisted, a sling needs to be installed on the surface of the material, and then the sling is hung on the hook to perform the hoisting operation, or a clamp is installed under the hook to clamp the material for hoisting operation.

[0048] In the prior art, when installing slings for lifting materials with irregular shapes or large sizes, the operation is cumbersome and complicated, and when installing the clamps, the clamps need to be frequently installed or removed according to needs to lift the materials, which increases the lifting time and reduces the lifting efficiency.

[0049] In order to solve the above problems, the present invention has the following working principle: under the normal state of the clamp mechanism of the device, the two moving blocks 64 are attached to each other, and the placement plate 71 is inclined. The hoist 4 of the device is an intelligent hoist 4 in the prior art, and its composition structure and connection method are exactly the same as those of the existing device;

[0050] When it is necessary to hoist the material with the lifting ring, the fixed frame 6 is driven to move downward, the moving block 64 of the fixed frame 6 is lowered, the moving block 64 drives the rotating frame 7 to lower, and the rotating frame 7 drives the placing plate 71 to move to a suitable position, so that the placing plate 71 passes through the inside of the lifting ring of the material, and then the lifting ring is limited by the baffle 73, so that the lifting ring stays above the placing plate 71, and the fixing of the material is completed;

[0051] When it is necessary to fix the material without the ring, the moving block 64 is driven to slide inside the fixed frame 6, so that the two moving blocks 64 move away from each other, and the two moving blocks 64 respectively drive the rotating frames 7 below them to move away from each other, so that the material moves to between the two rotating frames 7. At this time, the rotating frames 7 are driven to move closer to each other, so that the side walls of the two rotating frames 7 and the side walls of the material fit together. At this time, the material is fixedly clamped between the two rotating frames 7;

[0052] When the material is fixed, the user holds the control handle 41, and the infrared sensor under the control handle 41 automatically identifies and switches from the locking mode to the hand-holding mode. In the hand-holding mode, the operator can use the control handle 41 to drive the support rod 3 to rotate around the cross bar 2 to complete the lifting operation of the material in the X and Y axis. On the basis of the hand-holding mode, the operator can long press the up or down button on the handle to make the intelligent hoist 4 enter the suspension mode. When the sensor inside the control handle 41 detects that the state of the load has changed, it will immediately feed back this information to the control system. The control system adjusts the output of the servo motor 62 according to the feedback information. The servo motor 62 reels the connecting rope and uses the spring to ensure that the load can remain in a suspended state. After entering the suspension mode, the operator can drive the material to move in the Z axis direction, thereby completing the three-axis motion lifting operation;

[0053] This structure can convert the hook into a splint to fix the material without the lifting ring to facilitate the subsequent lifting operation. The appropriate lifting method can be selected according to the different types of materials, which increases the flexibility of use.

[0054] like Figure 2 and Figure 3 As shown, a bidirectional screw rod 61 is symmetrically rotatably connected between the inner walls of the fixed frame 6, the surface of the bidirectional screw rod 61 is connected to the internal thread of the moving block 64, one end of the bidirectional screw rod 61 is fixedly connected to a pulley 63, and the two pulleys 63 are connected by a belt drive, and a motor 62 is fixedly connected to one side of the fixed frame 6, and the output end of the motor 62 is fixedly connected to one end of one of the bidirectional screw rods 61.

[0055] Specifically, the motor 62 is turned on, and the motor 62 drives the single bidirectional screw 61 to rotate, so that the single bidirectional screw 61 drives the pulley 63 to rotate, and the other bidirectional screw 61 rotates synchronously through the belt transmission. The two bidirectional screws 61 rotate synchronously, and the moving blocks 64 can be driven to slide away from or close to each other inside the fixed frame 6;

[0056] This structure can drive the moving block 64 to drive the two rotating frames 7 to move closer to each other to form a hook, or drive the two rotating frames 7 to move away from each other to form a clamp to meet different lifting requirements.

[0057] like Figure 4 and Figure 5 As shown, the rotating end of the baffle 73 is fixedly connected to a ratchet 731, and one side of the rotating frame 7 is rotatably connected to a pawl 732. The pawl 732 and the ratchet 731 are unidirectionally meshed, and a limiting spring 733 is fixedly connected between one end of the pawl 732 and one side of the rotating frame 7.

[0058] Specifically, the baffle plate 73 is then driven to rotate toward the inner wall of the rotating frame 7, and the baffle plate 73 drives the ratchet wheel 731 to rotate, so that a gap is formed between the baffle plate 73 and the placement plate 71, and then the lifting ring can be placed on the upper surface of the placement plate 71 through the above gap, and then the baffle plate 73 is driven to reset and contact with the upper surface of the placement plate 71, and then the ratchet 732 is moved and the limit spring 733 is squeezed, so that the limit spring 733 is reset and drives the ratchet 732 and the ratchet wheel 731 to mesh, so that the baffle plate 73 is limited;

[0059] This device can limit the baffle 73 in one direction, so that the baffle 73 can limit the hoisted materials, avoiding the problem that the lifting ring above the placement plate 71 is separated from the top of the placement plate 71 due to vibration.

[0060] like Figure 6 and Figure 7As shown, the interior of the moving block 64 is rotatably connected with a rotating rod 65, one end of the rotating rod 65 is fixedly connected with a rotating plate 66, one end of the rotating plate 66 is fixedly connected with a limiting rod 661, and a limiting groove 8 is symmetrically arranged on the inner upper surface of the fixed frame 6, the limiting groove 8 includes a first parallel section 81, one end of the first parallel section 81 is provided with an inclined section 82, one end of the inclined section 82 is provided with a second parallel section 83, and one side of the second parallel section 83 is provided with an extension section 84, one end of the limiting rod 661 is slidably connected to the inner wall of the limiting groove 8, the surface of the rotating rod 65 is fixedly connected with a plurality of ribs 651, the ribs 651 are slidably connected to the upper surface of the rotating frame 7, the rotating rod 65 and the rotating frame 7 are meshed and connected through the ribs 651, one end of the rotating rod 65 is rotatably connected with a connecting rod 72, the other end of the connecting rod 72 is rotatably connected to the upper surface of the placing plate 71, and an extrusion spring 67 is fixedly connected between the surface of the rotating rod 65 and the inner wall of the rotating frame 7.

[0061] Specifically, when the two sides of the two rotating frames 7 are in a contact state, the limiting rod 661 is inside the first parallel section 81 of the limiting groove 8, and when the moving block 64 drives the rotating frames 7 to move away from each other, the rotating frames 7 drive the rotating rod 65 inside thereof to slide synchronously, and the rotating rod 65 drives the limiting rod 661 on the surface of the rotating plate 66 to slide synchronously, and the limiting rod 661 slides inside the first parallel section 81, and the rotating frames 7 do not rotate at this time;

[0062] Then, the limiting rod 661 slides from the first parallel section 81 to the inclined section 82 and slides inside the inclined section 82. At this time, the limiting rod 661 drives the rotating plate to rotate, and the rotating plate can drive the rotating rod 65 to rotate. The rotating rod 65 engages with the inner wall of the rotating frame 7 through the ribs 651 on the surface. At the same time, the rotating rod 65 drives the extrusion spring 67 to twist. Then, the rotating rod 65 can drive the rotating frame 7 to rotate synchronously while rotating.

[0063] When the limiting rod 661 slides from the inclined section 82 to the second parallel section 83 and slides in the second parallel section 83, the rotating plate drives the rotating rod 65 to rotate, and the rotating rod 65 drives the rotating frame 7 and the placement plate 71 inside it to rotate counterclockwise by 90 degrees, so that the two symmetrically arranged placement plates 71 point to each other;

[0064] This structure can automatically drive the rotating frame 7 to rotate when the moving block 64 moves, and at the same time, the rotating frame 7 can be limited by the limit groove 8. Compared with the prior art driven by the motor 62, it has the following advantages: simple operation, no manual operation by the staff, and at the same time, during the hoisting process, the limit groove 8 can limit the limit rod 661, so that the rotating frame 7 remains stable, avoiding the motor 62 from being affected by factors such as electromagnetic interference, power supply fluctuations or hoisting vibrations, resulting in unstable performance or failure, thereby affecting the subsequent clamping operation of the material.

[0065] like Figure 7 and Figure 8 As shown, the upper surface of the rotating plate 66 is symmetrically fixedly connected with a squeezing rod 662 , the inner upper surface of the fixing frame 6 is symmetrically fixedly connected with a squeezing plate 9 , and the interior of the squeezing plate 9 is slidably connected with a convex plate 91 .

[0066] Specifically, when the limit rod 661 slides in the second parallel section 83, the extrusion rod 662 above the rotating plate 66 slides synchronously with the rotating plate 66, and then the extrusion rod 662 contacts one side of the convex plate 91, so that the extrusion rod 662 slides on the side surface of the convex plate 91 and moves downward, the extrusion rod 662 drives the rotating plate 66 to move downward, and the rotating plate 66 drives the rotating rod 65 to move downward, and the rotating rod 65 slides downward on the inner wall of the rotating frame 7 through the rib 651. At the same time, the rotating rod 65 drives the extrusion spring 67 to press down, and after the rotating rod 65 descends, it drives the connecting rod 72 to rotate synchronously, and the connecting rod 72 drives the placement plate 71 at one end thereof to rotate synchronously, so that the placement plate 71 and the rotating frame 7 are perpendicular to each other, and then the extrusion rod 662 continues to slide, and slides from the lower surface of the convex plate 91 to the lower surface of the extrusion plate 9, so that the placement plate 71 and the rotating frame 7 remain perpendicular to each other. When the material is clamped later, the placement plate 71 can support the lower surface of the material.

[0067] This structure can drive the placement plate 71 to rotate so that the placement plate 71 and the rotating frame 7 are in a mutually perpendicular state, thereby facilitating the subsequent clamping of the material to support the lower surface of the material and avoiding the problem of the material sliding and falling between the rotating frames 7 due to external shaking in the clamping and hoisting state.

[0068] like Figure 8 As shown, the upper surface of each convex plate 91 is fixedly connected with a first positioning rod 92, one end of the first positioning rod 92 is fixedly connected with a magnetic plate 93, the upper surface of the fixed frame 6 is fixedly connected with an electromagnet 10, the magnetism of the electromagnet 10 and the magnetism of the magnetic plate 93 repel each other after power is turned on, the internal sliding connection of the magnetic plate 93 is connected with a second positioning rod 94, the second positioning rod 94 is fixedly connected to the upper surface of the fixed frame 6, and a positioning spring 95 is fixedly connected between the magnetic plate 93 and the upper surface of the fixed plate 66.

[0069] Specifically, when the material to be clamped is between the sum of the lengths of the inclined section 82 and the first parallel section 81, the limit rod 661 will be reset to the inside of the inclined section 82 or the first parallel section 81, so that when the rotating frame 7 is clamping the building material, the placement plate 71 can no longer support the lower surface of the material, thereby causing the material to slide and fall from the rotating frame 7 when the outside world shakes in the clamping and hoisting state;

[0070] In order to solve the above problems, the working principle of the device is as follows: the electromagnet 10 is energized, and the magnetism of the electromagnet 10 and the magnetism of the magnetic plate 93 repel each other, so that the magnetic plate 93 slides on the surface of the second positioning rod 94 and squeezes the positioning spring 95. At this time, the magnetic plate 93 drives the first positioning rod 92 to slide synchronously, and the first positioning rod 92 drives the convex plate 91 to slide on the inner wall of the squeezing plate 9, so that the convex plate 91 slides to one side of the first parallel section 81;

[0071] This structure can drive the protruding plate 91 to extend, so that the distance that the protruding plate 91 and the extrusion plate 9 press down on the extrusion rod 662 increases, which is used to facilitate the subsequent support operation below the material whose length is less than the sum of the lengths of the inclined section 82 and the first parallel section 81.

[0072] like Figures 9 to 10 As shown, the lower surface of the magnetic plate 93 is slidably connected with a first protrusion 931, the lower surface of the first protrusion 931 is slidably connected with a first connecting rod 822, the first connecting rod 822 and the upper surface of the fixing frame 6 are fixedly connected, a first connecting spring 823 is fixedly connected between the first connecting rod 822 and the upper surface of the fixing frame 6, one end of the first connecting rod 822 is fixedly connected with a first slider 821, and the first slider 821 is slidably connected to the inside of the inclined section 82.

[0073] like Fig. 9 and 11 As shown, a second protrusion 932 is fixedly connected to the lower surface of the magnetic plate 93 and located on one side of the first protrusion 931, a second connecting rod 842 is slidably connected to the lower surface of the second protrusion 932, the second connecting rod 842 and the upper surface of the fixing frame 6 are fixedly connected, a second connecting spring 843 is fixedly connected between the second connecting rod 842 and the upper surface of the fixing frame 6, one end of the second connecting rod 842 is fixedly connected to the second slider 841, and the first slider 821 is slidably connected to the inside of the extension section 84.

[0074] Specifically, under normal conditions, the second protrusion 932 is in an extrusion state with respect to the second connecting rod 842. When the magnetic plate 93 slides on the surface of the second positioning rod 94, the magnetic plate 93 drives the first protrusion 931 to slide synchronously. The first protrusion 931 moves and presses the first connecting rod 822 downward. The first connecting rod 822 drives the first slider 821 to move downward and squeeze the first connecting spring 823, so that the first slider 821 slides out of the inclined section 82 and blocks the distance between the second parallel section 83 and the inclined section 82, so that the limit rod 661 cannot be reset to enter the inclined section 82. At the same time, the magnetic plate 93 drives the second protrusion 932 to synchronously The sliding makes the second connecting spring 843 drive the second connecting rod 842 to rise, and the second connecting rod 842 drives the second slider 841 to rise, and the second slider 841 slides out from the extension section 84, so that the extension section 84 is opened. When the subsequent moving block 64 drives the rotating rod 65 to reset, the rotating rod 65 is limited by the first slider 821, so that the rotating rod 65 slides into the extension section 84. At the same time, the extrusion rod 662 is now under the convex plate 91 in the extended state, and then the material whose length is less than the sum of the lengths of the inclined section 82 and the first parallel section 81 can be clamped below and the material can be supported and limited below.

[0075] like Figure 6 As shown, the interior of the placement plate 71 is slidably connected with a support plate 711 , and a support spring 712 is fixedly connected between one end of the support plate 711 and the inner wall of the placement plate 71 .

[0076] Specifically, when one end of the two placement plates 71 point to each other and are close to each other and one end is in contact with each other, the rotating frame 7 then drives the placement plates 71 to continue to move closer, and one end of the placement plates 71 squeezes the support plate 711 inside the squeezer, so that the support plate 711 slides inside the placement plates 71 and squeezes the support spring 712, thereby preventing one end of the placement plates 71 from being in contact and unable to move, thereby limiting the movement of the rotating frame 7 and making it impossible to fix the material.

[0077] The locking cam 731 is pressed against the locking cam 74 to lock the locking cam 74, and the locking cam 732 is in a state of being pushed against the locking cam 74 so as to lock the locking cam 74. When the locking cam 73 is in a state of being pushed against the locking cam 74, the locking cam 732 is in a state of being pushed against the locking cam 74.

[0078] When it is necessary to fix the material without the ring, turn on the motor 62, the motor 62 drives the single bidirectional screw rod 61 to rotate, so that the single bidirectional screw rod 61 drives the pulley 63 to rotate, and through the belt transmission, the other bidirectional screw rod 61 rotates synchronously. The two bidirectional screw rods 61 rotate synchronously, and the moving block 64 can be driven to slide away from or towards each other inside the fixed frame 6, and the moving block 64 is driven to slide inside the fixed frame 6, so that the two moving blocks 64 move away from each other, and the two moving blocks 64 respectively drive the rotating frames 7 below them to move away from each other, so that the material moves between the two rotating frames 7. At this time, the rotating frames 7 are driven to move closer to each other, so that the side walls of the two rotating frames 7 and the side walls of the material fit together. At this time, the material is fixedly clamped between the two rotating frames 7;

[0079] When the two sides of the two rotating frames 7 are in a fitted state, the limiting rod 661 is inside the first parallel section 81 of the limiting groove 8. When the moving block 64 drives the rotating frames 7 to move away from each other, the rotating frames 7 drive the rotating rod 65 inside thereof to slide synchronously, and the rotating rod 65 drives the limiting rod 661 on the surface of the rotating plate 66 to slide synchronously. The limiting rod 661 slides inside the first parallel section 81, and the rotating frames 7 do not rotate at this time.

[0080] Then, the limiting rod 661 slides from the first parallel section 81 to the inclined section 82 and slides inside the inclined section 82. At this time, the limiting rod 661 drives the rotating plate to rotate, and the rotating plate can drive the rotating rod 65 to rotate. The rotating rod 65 engages with the inner wall of the rotating frame 7 through the ribs 651 on the surface. At the same time, the rotating rod 65 drives the extrusion spring 67 to twist. Then, the rotating rod 65 can drive the rotating frame 7 to rotate synchronously while rotating.

[0081] When the limiting rod 661 slides from the inclined section 82 to the second parallel section 83 and slides in the second parallel section 83, the rotating plate drives the rotating rod 65 to rotate, and the rotating rod 65 drives the rotating frame 7 and the placement plate 71 inside it to rotate counterclockwise by 90 degrees, so that the two symmetrically arranged placement plates 71 point to each other;

[0082] When the limiting rod 661 slides in the second parallel section 83, the extrusion rod 662 above the rotating plate 66 slides synchronously with the rotating plate 66, and then the extrusion rod 662 contacts one side of the convex plate 91, so that the extrusion rod 662 slides on the side surface of the convex plate 91 and moves downward, the extrusion rod 662 drives the rotating plate 66 to move downward, and the rotating plate 66 drives the rotating rod 65 to move downward, and the rotating rod 65 slides downward on the inner wall of the rotating frame 7 through the rib 651. At the same time, the rotating rod 65 drives the extrusion spring 67 to press down, and after the rotating rod 65 descends, it drives the connecting rod 72 to rotate synchronously, and the connecting rod 72 drives the placing plate 71 at one end thereof to rotate synchronously, so that the placing plate 71 and the rotating frame 7 are perpendicular to each other, and then the extrusion rod 662 continues to slide, and slides from the lower surface of the convex plate 91 to the lower surface of the extrusion plate 9, so that the placing plate 71 and the rotating frame 7 remain perpendicular to each other. When the material is clamped later, the placing plate 71 can support the lower surface of the material.

[0083] When the clamped material needs to be between the sum of the lengths of the inclined section 82 and the first parallel section 81, the electromagnet 10 can be energized, and the magnetism of the electromagnet 10 and the magnetism of the magnetic plate 93 repel each other, so that the magnetic plate 93 slides on the surface of the second positioning rod 94 and squeezes the positioning spring 95. At this time, the magnetic plate 93 drives the first positioning rod 92 to slide synchronously, and the first positioning rod 92 drives the convex plate 91 to slide on the inner wall of the squeezing plate 9, so that the convex plate 91 slides to one side of the first parallel section 81;

[0084] The magnetic plate 93 drives the first protrusion 931 to slide synchronously, and the first protrusion 931 moves and presses the first connecting rod 822 downward. The first connecting rod 822 drives the first slider 821 to move downward and press the first connecting spring 823, so that the first slider 821 slides out of the inclined section 82 and blocks the distance between the second parallel section 83 and the inclined section 82, so that the limit rod 661 cannot be reset to enter the inclined section 82. At the same time, the magnetic plate 93 drives the second protrusion 932 to slide synchronously, so that the second connecting spring 843 drives the second connecting rod 842 upward. The second connecting rod 842 drives the second slider 841 to rise, and the second slider 841 slides out of the extension section 84, so that the extension section 84 is opened. When the subsequent moving block 64 drives the rotating rod 65 to reset, the rotating rod 65 is limited by the first slider 821, so that the rotating rod 65 slides into the extension section 84. At the same time, the squeezing rod 662 is now under the convex plate 91 in the extended state, and then the material whose length is less than the sum of the lengths of the inclined section 82 and the first parallel section 81 can be clamped below and the material can be supported and limited below.

[0085] When one end of the two placement plates 71 points to each other and approaches each other and one end contacts each other, the rotating frame 7 then drives the placement plates 71 to continue to approach, and one end of the placement plates 71 squeezes the support plate 711 inside the squeezer, so that the support plate 711 slides inside the placement plates 71 and squeezes the support spring 712, so that the material slides through the oblique edge of the support plate 711 to the top of the placement plates 71 for storage support;

[0086] When the material is fixed, the user holds the control handle 41, and the infrared sensor under the control handle 41 automatically identifies and switches from the locking mode to the hand-holding mode. In the hand-holding mode, the operator can use the control handle 41 to drive the support rod 3 to rotate around the cross bar 2 to complete the lifting operation of the material in the X and Y axes. On the basis of the hand-holding mode, the operator can press and hold the up or down button on the handle to make the intelligent hoist 4 enter the suspension mode. When the sensor inside the control handle 41 detects that the state of the load has changed, it will immediately feed back this information to the control system. The control system adjusts the output of the servo motor 62 according to the feedback information. The servo motor 62 reels the connecting rope and uses the spring to ensure that the load can remain in a suspended state. After entering the suspension mode, the operator can drive the material to move in the Z-axis direction, thereby completing the three-axis motion lifting operation.
