[0002] A self-balancing concrete component lifting device is typically used to safely and efficiently lift precast concrete components during construction. This device is designed to reduce the risks of manual operation, improve lifting accuracy, and adapt to varying construction site conditions.

[0003] Existing lifting devices mostly use multiple steel wire ropes with hooks at the tail ends to hook and cooperate with the lifting rings on the concrete components to lift the concrete components. However, during the lifting and hoisting process, multiple hooks and multiple lifting rings need to be hooked and separated and disassembled step by step. The operation is relatively cumbersome and inconvenient, which indirectly reduces the efficiency of the lifting operation of the concrete components. Utility Model Content

[0004] In view of this, the utility model provides a self-balancing concrete component lifting device to solve the problem that during the lifting and hoisting process, multiple hooks and multiple lifting rings need to be hooked, matched, separated and disassembled step by step, which is troublesome and inconvenient to operate.

[0005] The technical solution proposed by the utility model is: a self-balancing concrete component lifting device, specifically comprising: a main frame and a concrete component, wherein four lifting rings are symmetrically cast and fixed on the top of the concrete component; the main frame is an elongated rectangular structure as a whole;

[0006] Two longitudinal slide bars are symmetrically slidably installed on the main frame, and two L-shaped plug-in hangers are symmetrically slidably installed on the longitudinal slide bars. The four L-shaped plug-in hangers are arranged to support each other and correspond to the four hanging ring plug-in hooks.

[0007] A vertical positioning shaft is welded to the top of the central part of the main frame, and a hanging assembly is slidably installed on the vertical positioning shaft; the hanging assembly as a whole is composed of two U-shaped frames set at intervals and semicircular hanging rings welded to the top of the two U-shaped frames, and two connecting rods are symmetrically connected to the hanging assembly and the two longitudinal sliding rods.

[0008] Further,

[0009] Two short mounting shafts are symmetrically welded between the top parts of the two U-shaped frames, the head ends of the two connecting rods are rotatably connected to the two short mounting shafts, and a shaft sleeve is welded between the middle positions of the bottom sides of the two U-shaped frames, and the shaft sleeve is slidably fitted with the vertical positioning shaft.

[0010] Further,

[0011] Two synchronous drive shafts are symmetrically and slidably installed on the top parts of the four L-shaped plug-in hangers.

[0012] Further,

[0013] A longitudinally arranged double-rotational threaded shaft is rotatably installed on the bottom side of the center position of the main frame, and two reverse threaded sections of the double-rotational threaded shaft are correspondingly threadedly fitted through the middle parts of the two synchronous drive shafts.

[0014] Further,

[0015] The longitudinal sliding rod and the synchronous driving shaft are both hexagonal structures.

[0016] Further,

[0017] A U-shaped connecting frame supporting upward is welded to the middle part of the longitudinal sliding rod, and the tail end of the connecting rod is rotatably connected to the U-shaped connecting frame.

The two connecting rods can then serve as the transmission components of the lifting force, and can also be used to drive the four L-shaped plug-ins and four lifting rings to hook, connect, separate and disassemble, achieving the effect of a dual-purpose device.

[0021] 3. Through the coordinated sliding of two synchronous drive shafts and two longitudinal slide bars, the four L-shaped plug-in parts can be adjusted in the left and right and front and back dimensions.

[0034] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the described 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.

[0035] For the convenience of description, the length direction of the main frame is calibrated as the left-right direction, and the width direction is calibrated as the front-back direction.

[0036] Please refer to Figures 1 to 5 ;

[0037] Example 1:

[0038] The utility model proposes a self-balancing concrete component lifting device, comprising: a main frame 1 and a concrete component 2, wherein four lifting rings 201 are symmetrically cast and fixed on the top of the concrete component 2; the main frame 1 is an elongated rectangular structure as a whole;

[0039] Two longitudinal slide bars 101 are symmetrically slidably installed on the main frame 1, and two L-shaped plug-in hangers 1011 are symmetrically slidably installed on the longitudinal slide bars 101. The four L-shaped plug-in hangers 1011 are arranged to support each other and correspondingly engage with the four hanging rings 201 for plugging and hooking.

[0040] A vertical positioning shaft 102 is welded to the top of the central part of the main frame 1, and a hanging assembly 3 is slidably mounted on the vertical positioning shaft 102; the hanging assembly 3 is composed of two U-shaped frames spaced apart and semicircular hanging rings welded to the top of the two U-shaped frames, and two connecting rods 303 are symmetrically connected to the hanging assembly 3 and the two longitudinal sliding rods 101.

[0041] The hanging assembly 3, the two connecting rods 303 and the two longitudinal slide bars 101 are connected together to form two crank slider mechanisms. Through these two mechanisms, the up and down sliding hanging assembly 3 can drive the two longitudinal slide bars 101 to slide left and right toward each other, controlling the four left and right L-shaped plug hangers 1011 and the four lifting rings 201 to be synchronously inserted and pulled together at one time, implementing hook connection and separation and disassembly, eliminating the trouble of hooking and disassembling the four L-shaped plug hangers 1011 and the four lifting rings 201 step by step, and helping to improve the efficiency of the hoisting operation of the concrete component 2 compared with the existing technology;

[0042] During hoisting, the hook of the hoisting equipment is connected with the semicircular lifting ring at the top of the hanging component 3. When the hoisting equipment lifts the concrete component 2, the lifting force of the hoisting equipment will pull the hanging component 3 upward, pushing the four L-shaped plug-ins 1011 to keep them in the state of use in which they are plugged into and hooked with the four lifting rings 201, thereby preventing the four L-shaped plug-ins 1011 from being disconnected and separated from the four lifting rings 201 during the hoisting process, causing the concrete component 2 to fall from a high altitude.

[0043] The lifting force of the lifting equipment is transmitted to the concrete component 2 through the hanging assembly 3 and the two connecting rods 303. The two connecting rods 303 can then serve as the lifting force transmission components and can also be used to drive the four L-shaped plug-in hangers 1011 to hook and connect with the four lifting rings 201 and to separate and disassemble them, achieving a dual-purpose use effect.

[0044] By means of the two crank slider mechanisms, the hanging assembly 3 can be slid up and down to drive the two longitudinal slide bars 101 to slide left and right toward each other, thereby adjusting the spacing between the four L-shaped hanging members 1011 on the left and right sides, so that the four L-shaped hanging members 1011 can be hooked with the four hanging rings 201 arranged at different spacings in the length direction of the concrete member 2;

[0045] When the concrete component 2 is lifted up, the center of gravity of it and the lifting device as a whole is placed directly below the hook of the lifting equipment. At this time, the concrete component 2 and the lifting device can use their vertical gravity to swing along the hook and automatically correct to directly below the hook and automatically level.

[0046] Preferably,

[0047] Two mounting short shafts 302 are symmetrically welded between the top parts of the two U-shaped frames, the head ends of the two connecting rods 303 are rotatably connected to the two mounting short shafts 302, and a shaft sleeve 301 is welded between the middle positions of the bottom sides of the two U-shaped frames, and the shaft sleeve 301 is slidably fitted with the vertical positioning shaft 102.

[0048] Preferably,

[0049] A U-shaped connecting frame 1012 supporting the vehicle upward is welded to the middle portion of the longitudinal sliding rod 101 , and the tail end of the connecting rod 303 is rotatably connected to the U-shaped connecting frame 1012 .

[0050] Based on the first embodiment, the second embodiment:

[0051] Two synchronous drive shafts 104 are symmetrically and slidably installed on the top parts of the four L-shaped plug-in hangers 1011; a longitudinally arranged double-rotation threaded shaft 103 is rotatably installed on the bottom side of the center position of the main frame 1, and the two oppositely threaded sections of the double-rotation threaded shaft 103 are correspondingly threaded and screwed into the middle parts of the two synchronous drive shafts 104;

[0052] The forward and reverse rotating double-direction threaded shaft 103 can synchronously drive the two synchronous drive shafts 104 to slide toward each other back and forth, adjust the spacing between the four front and rear L-shaped plug-ins 1011, so that the four L-shaped plug-ins 1011 are suitable for hooking and cooperating with the four lifting rings 201 with different spacings in the width direction of the concrete component 2, and then through the sliding use of the two synchronous drive shafts 104 and the two longitudinal sliding rods 101, the four L-shaped plug-ins 1011 can be adjusted in spacing in two dimensions, left and right and front and back, and are suitable for hooking and cooperating with the four lifting rings 201 with different distribution spacings on different concrete components 2, so that the lifting device can be compatible with lifting concrete components 2 of different length and width specifications, expanding the wide application of the lifting device.

[0053] Preferably,

[0054] The longitudinal slide bar 101 and the synchronous drive shaft 104 are both hexagonal structures.

[0055] The working principle of this embodiment is as follows: when hoisting, the hook of the hoisting equipment is connected with the semicircular lifting ring at the top of the hanging component 3, and the four L-shaped plug-in parts 1011 are plugged and hooked with the four lifting rings 201;

[0056] The hanging assembly 3, the two connecting rods 303 and the two longitudinal slide bars 101 are connected together to form two crank slider mechanisms. Through these two mechanisms, the up and down sliding hanging assembly 3 can drive the two longitudinal slide bars 101 to slide left and right toward each other, controlling the four left and right L-shaped plug-in parts 1011 to synchronize with the four hanging rings 201 for one-time insertion and insertion, thus implementing hook connection and separation and disassembly.

[0057] When the hoisting equipment lifts the concrete component 2, the lifting force of the hoisting equipment will pull the hanging assembly 3 upward, pushing the four L-shaped hanging pieces 1011 to keep them in the state of use in which they are plugged into and hooked with the four lifting rings 201, thereby preventing the four L-shaped hanging pieces 1011 from being disconnected and separated from the four lifting rings 201 during the hoisting process, causing the concrete component 2 to fall from a high altitude.

[0058] When the concrete component 2 is lifted, the center of gravity of the concrete component 2 and the lifting device is placed directly below the hook of the lifting equipment. At this time, the concrete component 2 and the lifting device can automatically swing along the hook and automatically level themselves by using their vertical gravity.

[0059] Through the coordinated sliding use of two synchronous drive shafts 104 and two longitudinal slide bars 101, the four L-shaped plug-in hangers 1011 can be adjusted in spacing in the left and right and front and back dimensions, and are suitable for hooking with four lifting rings 201 with different distribution spacings on different concrete components 2, so that the lifting device can be compatible with lifting concrete components 2 of different length and width specifications.
