Technical Field

[0001] The invention relates to the field of hanging technology, and in particular to a temporary hanging device for a prefabricated steel cage in a highway reconstruction and expansion project. Background Art

[0002] The prefabricated steel cage lifting device is a combination of equipment or tools used to lift and carry prefabricated steel cages. The lifting device can lift, move and place the prefabricated steel cage from one location to another, and is widely used in many fields such as construction, manufacturing, logistics, etc. Its core function is to use mechanical principles to overcome the effect of gravity on heavy objects and achieve the spatial position transfer of heavy objects. At present, the prefabricated steel cage lifting device uses a single hook or a double hook for hanging. The prefabricated steel cage is unstable when moving, and the steel cage shakes too much when hanging, which is easy to cause collision and damage to the steel cage body. Summary of the invention

[0003] Based on this, it is necessary to provide a temporary lifting device for prefabricated steel cages in highway reconstruction and expansion projects to solve at least one of the above technical problems.

The upper end of the sliding block is slidably engaged in the sliding groove, the tops of the two connecting rods are fixedly connected to the bottom of the sliding block, and the top of the storage body is fixedly connected to the bottom of the connecting rod.

[0009] In one embodiment, two horizontal sliding grooves are opened at the two ends of the top of the storage body, and the two horizontal sliding grooves both pass through the upper and lower surfaces of the storage body. Two front and rear sliding grooves are opened at the other two ends of the top of the storage body, and the two front and rear sliding grooves both pass through the upper and lower surfaces of the storage body. Each horizontal sliding groove and the side wall of each front and rear sliding groove are provided with a locking groove.

[0010] In one embodiment, two horizontally movable hook assemblies are respectively slidably clamped in two horizontal sliding grooves, and two front-and-rear movable hook assemblies are respectively slidably clamped in two front-and-rear sliding grooves. Each horizontally movable hook assembly and each front-and-rear movable hook assembly include a sliding body, a chain storage box, an iron rope and a magnet hook. The sliding body is slidably clamped in the horizontal sliding groove or the front-and-rear sliding groove.

The top of the metal segment is hingedly connected to the side wall of the accommodating groove, and the top of the cable segment is fixedly connected to the bottom of the metal segment.

[0013] In one embodiment, each fixing component includes an upper magnet fixing part and a lower telescopic part, both of which are fixedly mounted on the outside of the connecting part, and the upper magnet fixing part is located above the lower telescopic part.

[0015] The present invention arranges electromagnets. When the steel cage is hoisted to the highest point, each electromagnet is electrically connected to the controller, the electromagnet power supply is started, the electromagnet conducts electricity to generate a magnetic field, and the electromagnet moves upward along the cable segment, so that the upper end of the electromagnet can enter the clamping groove under the guidance of the guide groove.

[0017] By setting an electric push rod, when the connecting piece is not needed, the connecting piece can be stored in the storage groove. When it is found that the steel cage shakes too much during hanging, multiple electric push rods can be started through the controller, so that the multiple electric push rods rise downward, so that the connecting piece is pushed out by the electric push rod. After the two connecting pieces are pushed out of the storage groove, they are respectively located on the inner and outer sides of the steel cage. The electromagnet power supply is started, and the electromagnet conducts electricity to generate a magnetic field. The electromagnet moves upward along the cable segment, so that the upper end of the electromagnet can enter the clamping groove under the guidance of the guide groove, and the top of the electromagnet can abut on the magnet, so that the fixing component is in a straight line as a whole, to prevent the steel cage from being damaged by collision or causing damage to the lifting mechanism due to excessive shaking of the iron cable when the steel cage is moving.

[0018] The present invention has a simple structure and can adjust the hoisting position according to the shape of the steel cage. The four hooks can make the steel cage more stable when hanging. At the same time, by arranging a horizontal fixing component and a front and rear fixing component, the iron cable can be fixed when the steel cage shakes too much to prevent the steel cage from being damaged by collision or causing damage to the hoisting mechanism.

[0038] like Figure 6 As shown, two receiving grooves 335 are formed at the bottom of the sliding body 330 , and a plurality of electric push rods 336 are installed on the top side wall of each receiving groove 335 . A receiving groove 337 is formed on the side wall of one end of each receiving groove 335 adjacent to the connecting rod 311 .

[0039] like Figures 3 to 6 and Figure 8 As shown, the top of the connecting member 40 is hingedly connected to the side wall of the accommodating groove 337, and the connecting member 40 includes a metal segment 41 and a cable segment 42. The top of the metal segment 41 is hingedly connected to the side wall of the accommodating groove 337, and the top of the cable segment 42 is fixedly connected to the bottom of the metal segment 41.

[0040] like Figures 5 to 8 As shown, each fixing component 50 includes an upper magnet fixing part 51 and a lower telescopic part 52, and the upper magnet fixing part 51 and the lower telescopic part 52 are both fixedly mounted on the outside of the connecting part 40, and the upper magnet fixing part 51 is located above the lower telescopic part 52, and the upper magnet fixing part 51 includes a fixing body 510 and a magnet 511, the fixing body 510 is fixedly mounted on the outside of the connecting part 40, and a guide groove 512 is provided at the bottom of the fixing body 510, and a clamping groove 513 is provided at the top of the side wall of the guide groove 512, the magnet 511 is fixedly installed in the clamping groove 513, and the connecting part 40 is fixedly penetrated through the middle of the magnet 511.

[0041] like Figures 5 to 8 As shown, the lower telescopic member 52 includes a gravity containing box 520 and an electromagnet 521. The gravity containing box 520 is fixedly mounted on the outside of the connecting member 40, and the electromagnet 521 is slidably mounted on the outside of the connecting member 40. The electromagnet 521 is slidably received in the top of the gravity containing box 520, and the bottom of the gravity containing box 520 is fixedly connected to the top of the fixed body 510.

[0042] During installation: the support assembly 10 is installed on the ground, the two horizontal fixing assemblies 34 are respectively fixedly installed on the bottom of the two horizontal movable hook assemblies 32, the two front and rear fixing assemblies 35 are respectively fixedly installed on the bottom of the two front and rear movable hook assemblies 33, the fixing plate 11 is fixedly placed on the ground, and the chain storage box 331 is installed on the top of the sliding body 330.

[0043] When in use: 1. Adjust the controller according to the shape of the prefabricated steel cage. The controller is electrically connected to the lifting mechanism 30. The controller controls the sliding body 330 of the horizontal movable hook assembly 32 and the front-rear movable hook assembly 33 to move, so that the distance between the magnet hooks 333 of the two horizontal movable hook assemblies 32 is close to the size of the steel cage, and the distance between the magnet hooks 333 of the two front-rear movable hook assemblies 33 is close to the size of the steel cage. By setting four hooks, it is possible to prevent the steel cage from shaking too much during hanging and causing accidents.

[0044] 2. The controller is operated to release the iron ropes 332 in the four chain storage boxes 331, and the four magnet hooks 333 are clamped on the top of the steel cage. The two adjacent connecting pieces 40 are respectively placed on the inner and outer sides of the steel cage. The controller is operated to retract the iron ropes 332 in the four chain storage boxes 331, and the steel cage is hoisted. When the steel cage is hoisted to the highest point, each electromagnet 521 is electrically connected to the controller, and the power supply of the electromagnet 521 is started. The electromagnet 521 conducts electricity to generate a magnetic field, and the electromagnet 521 moves upward along the cable segment 42, so that the upper end of the electromagnet 521 can enter the guide groove 512 under the guidance of the guide groove 512. When the electromagnet 521 moves upward along the cable segment 42, the cable segment 42 will not be pulled up by the electromagnet 521, causing the cable segment 42 to bend and fold, and the top of the electromagnet 521 can abut against the magnet 511, so that the fixing component 50 is in a straight line as a whole. A plurality of fixing components 50 and the connecting member 40 form a fixed structure to prevent the steel cage from moving. Because the iron rope 332 shakes too much, the fixing component 50 can jam the steel cage, thereby preventing the steel cage from shaking and causing the iron rope 332 to shake, thereby causing the steel cage to collide and be damaged or causing damage to the lifting mechanism 30.

[0045] 3. When the electromagnet 521 conducts electricity to generate a magnetic field and the electromagnet 521 moves upward along the cable segment 42, the distance between the electromagnet 521 and the magnet 511 is smaller than the distance between the electromagnet 521 and the magnet hook 333, so that the upper end of the electromagnet 521 can enter the clamping groove 513 under the guidance of the guide groove 512, and the top of the electromagnet 521 can abut on the magnet 511, so that the fixing component 50 is in a straight line as a whole; when the fixing component 50 is in a straight line as a whole, the electromagnet 521 conducts electricity to generate a magnetic field, and the electromagnet 521 located at the magnet hook 333 will attract the magnet hook 333, so that the two side walls of the magnet hook 333 are respectively extended from the two adjacent electromagnets 521 or abut against the gravity containing box 520, thereby reducing the shaking of the iron rope 332 during movement, preventing the steel cage from shaking too much to cause collision or damage to the lifting mechanism 30.

[0046] 4. When the connector 40 is not needed, the connector 40 can be stored in the storage groove 335. When it is found that the steel cage is shaking too much during hanging, the multiple electric push rods 336 can be started by the controller, so that the multiple electric push rods 336 are raised downward, so that the connector 40 is pushed out by the electric push rods 336. After the two connectors 40 are pushed out of the storage groove 335, they are respectively located on the inner and outer sides of the steel cage, and the power supply of the electromagnet 521 is started. The electromagnet 521 conducts electricity to generate a magnetic field, and the electromagnet 521 moves upward along the cable segment 42, so that the electromagnet 521 can be guided by the guide groove 512. The upper end of the electromagnet 521 can enter the clamping groove 513, and the top of the electromagnet 521 can abut on the magnet 511, so that the fixing assembly 50 is in a straight line as a whole, to prevent the steel cage from being damaged by collision or causing damage to the lifting mechanism 30 due to excessive shaking of the iron rope 332 when the steel cage is moving. After the hanging is completed, the power supply of the electromagnet 521 is turned off, and the electromagnet 521 will fall into the gravity containing box 520 under the action of gravity. A triangular structure can be formed between the two horizontal movable hook assemblies 32 and the movable hanging member 31, and another triangular structure can be formed between the two front and rear movable hook assemblies 33 and the movable hanging member 31. The combination of the two triangular structures makes the steel cage more stable when hanging.

[0047] The present invention sets the electromagnet 521. When the steel cage is hoisted to the highest point, each electromagnet 521 is electrically connected to the controller, the power supply of the electromagnet 521 is started, the electromagnet 521 conducts electricity to generate a magnetic field, and the electromagnet 521 moves upward along the cable segment 42, so that the upper end of the electromagnet 521 can enter the clamping groove 513 under the guidance of the guide groove 512. The weight of the gravity containing box 520 is heavy, and when the electromagnet 521 moves upward along the cable segment 42, the cable segment 42 does not The electromagnet 521 will pull up the cable section 42 to bend in half, and the top of the electromagnet 521 can abut against the magnet 511, so that the fixing assembly 50 is in a straight line as a whole. Multiple fixing assemblies 50 and the connecting piece 40 form a fixed structure to prevent the steel cage from moving. Due to excessive shaking of the iron rope 332, the fixing assembly 50 can jam the steel cage to prevent the steel cage from shaking and causing the iron rope 332 to shake, thereby causing the steel cage to collide and be damaged or causing damage to the lifting mechanism 30.

[0048] By setting the electromagnet 521, when the electromagnet 521 conducts electricity to generate a magnetic field and moves upward along the cable segment 42, the distance between the electromagnet 521 and the magnet 511 is smaller than the distance between the electromagnet 521 and the magnet hook 333, so that the upper end of the electromagnet 521 can enter the clamping groove 513 under the guidance of the guide groove 512, and the top of the electromagnet 521 can abut on the magnet 511, so that the fixing component 50 is in a straight line as a whole; when the fixing component 50 is in a straight line as a whole, the electromagnet 521 conducts electricity to generate a magnetic field, and the electromagnet 521 located at the magnet hook 333 will attract the magnet hook 333, so that the two side walls of the magnet hook 333 are respectively abutted against the two adjacent electromagnets 521, thereby reducing the shaking of the iron rope 332 during movement, and preventing the steel cage from shaking too much to cause a collision or damage to the lifting mechanism 30.

[0049] By setting the electric push rod 336, when the connecting piece 40 is not needed, the connecting piece 40 can be stored in the storage groove 335. When it is found that the steel cage shakes too much during hanging, the multiple electric push rods 336 can be started by the controller, so that the multiple electric push rods 336 rise downward, so that the connecting piece 40 is pushed out by the electric push rod 336. After the two connecting pieces 40 are pushed out of the storage groove 335, they are respectively located on the inner and outer sides of the steel cage, and the power supply of the electromagnet 521 is started. The electromagnet 521 conducts electricity to generate a magnetic field. The electromagnet 521 moves upward along the cable segment 42, so that the upper end of the electromagnet 521 can enter the clamping groove 513 under the guidance of the guide groove 512, and the top of the electromagnet 521 can abut on the magnet 511, so that the fixing component 50 is in a straight line as a whole, so as to prevent the steel cage from being damaged by collision or causing damage to the lifting mechanism 30 due to excessive shaking of the iron rope 332 when the steel cage is moving.

[0050] The present invention has a simple structure and can adjust the hoisting position according to the shape of the steel cage. The four hooks can make the steel cage more stable when hanging. At the same time, by setting the horizontal fixing component 34 and the front and rear fixing components 35, the iron rope 332 can be fixed when the steel cage shakes too much to prevent the steel cage from being damaged by collision or causing damage to the hoisting mechanism 30.

[0051] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
