DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In one embodiment, referring to Figures 1 to 8 , a material lifting equipment for bridge construction, comprising a movable seat 1, on which two connecting shells 3 arranged parallel to the main reinforcement 4 of the steel cage are movably arranged, and the two connecting shells 3 are provided with a plurality of through holes 15 arranged at intervals on the sides away from each other, and a movable plate 13 is movably installed in the through hole 15, and a bayonet 14 is provided at one end of the movable plate 13 extending to the outside of the connecting shell 3, and a through hole 22 is provided at one end of the movable plate 13 extending to the inside of the connecting shell 3, and a plurality of hooks 9 arranged at intervals are provided on the outer wall of the connecting shell 3 for restraining the stirrups 5 of the steel cage, and the position of one end of the hook of the hook 9 corresponds to the opening position of the bayonet 14; a rope 2 is penetrated in the connecting shell 3, and the rope 2 is penetrated in the through hole 22, and a plurality of jacking protrusions 21 in groups of two are provided on the rope 2, and the outer diameter of the jacking protrusion 21 is larger than the inner diameter of the opening of the through hole 22, and two adjacent jacking protrusions 21 are respectively located on both sides of the movable plate 13.

[0025] When in use, first move one end of the connecting shell 3 to the end of the steel cage, move the connecting shell 3 and the movable seat 1 horizontally until the connecting shell 3 is penetrated and set in the steel cage, pull the rope 2 away from one end of the movable seat 1, as the rope 2 is pulled, the movable plate 13 in the connecting shell 3 also moves accordingly, and the pushing protrusion 21 on the side of the movable plate 13 close to the movable seat 1 pushes the end of the movable plate 13 located in the connecting shell 3 as the rope 2 moves, so that the end of the movable plate 13 located outside the connecting shell 3 flips in the direction away from the hook 9, and the hook 9 and the movable plate 13 are in an open state.

[0026] Then, adjust the horizontal position of the two connecting shells 3 until the side wall of the connecting shell 3 fits tightly with the inner wall of the steel cage. At this time, the stirrups 5 in the steel cage are accurately stuck between the opened hook 9 and the movable plate 13. Then pull the end of the rope 2 close to the movable seat 1, and the pushing protrusion 21 located on the side of the movable plate 13 away from the movable seat 1 pushes the movable plate 13, so that the end of the movable plate 13 located outside the connecting shell 3 is flipped toward the direction close to the hook 9 until the bent hook end of the hook 9 is stuck in the bayonet 14. At this time, the hook 9 and the movable plate 13 are in a closed state, and the stirrups 5 between the hook 9 and the movable plate 13 are constrained to complete the connection between the connecting shell 3 and the steel cage.

[0027] By lifting the end of the rope 2 close to the movable seat 1 through the lifting machinery, the vertical lifting of the steel cage is realized. The lifting space required for vertical lifting is small, and the movable seat 1 is horizontally set during the lifting process, and the outer diameter of the connecting shell 3 is small, that is, the wind resistance of the movable seat 1 and the connecting shell 3 is small, which reduces the influence of wind force during the lifting process and makes the lifting more stable; and during the lifting process, the end of the rope 2 close to the movable seat 1 is always in a pulled state, and under the action of the connecting shell 3 and the dead weight of the steel cage, the movable plate 13 and the hook 9 are always in a closed state, which can effectively restrain and lock the stirrups 5, effectively avoid the stirrups 5 from falling off, and improve the safety of lifting.

[0028] As a preferred embodiment of the present invention, an anti-collision end head 6 is provided at one end of the connection housing 3 away from the movable seat 1, and the anti-collision end head 6 adopts an arc surface structure design to effectively disperse the collision force that may be encountered during the movement of the connection housing 3. When pushing the connection housing 3, the anti-collision end head 6 can provide support for the end of the connection housing 3 to prevent the end from getting stuck or colliding with the stirrups 5 in the steel cage, thereby ensuring that the connection housing 3 can smoothly penetrate and move inside the steel cage.

[0029] In addition, the anti-collision end 6 is made of flexible material, which can effectively absorb the impact force during the contact process, further reducing the potential damage to the steel cage or other equipment components. The use of flexible material also enables the anti-collision end 6 to adapt to different collision angles and forces, thereby providing better protection.

[0030] In practical applications, the anti-collision end head 6 can significantly improve the compatibility and stability of the equipment with the steel cage during lifting and moving, avoid equipment damage or unsmooth operation due to unnecessary collisions, and ensure that the connecting shell 3 can be used smoothly and safely with the steel cage.

[0031] As a preferred embodiment of the present invention, a magnetic component 19 is provided on the side where the two anti-collision end heads 6 are close to each other. The purpose of this design is to use the magnetic components 19 to attract each other when the connection shell 3 is hoisted and moved without the steel cage loaded, so as to magnetically constrain the end of the connection shell 3. This can effectively prevent the connection shell 3 from swinging due to wind or other external forces during the hoisting process, thereby reducing potential safety hazards and ensuring the stability of the hoisting process.

[0032] The magnetic attraction component 19 tightly fixes the two anti-collision end heads 6 through magnetic force when the steel cage is not loaded, thereby avoiding unnecessary displacement or shaking of the connecting shell 3 and improving the stability and operational safety of the connecting shell 3 during the lifting process.

[0033] In addition, when the connecting housing 3 is pushed to move inside the steel cage, the two connecting housings 3 will naturally move together under the action of the magnetic attraction component 19, thereby enhancing the positioning accuracy of the connecting housing 3 in the steel cage and the operating efficiency of horizontal movement. The magnetic attraction component 19 can effectively reduce the difficulty of manual adjustment and positioning, thereby improving work efficiency and operating accuracy.

[0034] The magnetic design also has good adaptability and can provide flexible and stable support according to different operating environments and lifting conditions. It not only optimizes the use experience of the equipment, but also improves the overall safety of lifting and operation, and reduces the risks and accidents that may be caused to the equipment and operators during the lifting process.

[0035] As a preferred embodiment of the present invention, a handle 10 is provided at one end of the rope 2 extending to the side of the anti-collision end head 6 , and the rope 2 can be pulled by holding the handle 10 .

[0036] As a preferred embodiment of the present invention, a locking protrusion 12 is provided at one end of the hook of the hook 9, and this design is to enhance the friction between the hook 9 and the opening of the bayonet 14 when the hook of the hook 9 is inserted into the bayonet 14. The locking protrusion 12 ensures that the contact area between the hook 9 and the bayonet 14 is effectively increased through its specific shape and size after being inserted into the bayonet 14, thereby enhancing the friction between the two.

[0037] In this design, the locking protrusion 12 plays a role in enhancing the connection firmness, making the connection between the hook 9 and the bayonet 14 tighter, and preventing the hook from loosening or falling off due to external force or vibration. By increasing the friction force, the connection between the movable plate 13 and the hook 9 is more stable, effectively preventing the safety hazard caused by the unstable connection during the lifting process.

[0038] In addition, the locking protrusion 12 also has a self-locking function. When one end of the hook 9 is completely inserted into the bayonet 14, the locking protrusion 12 will automatically come into contact with the wall of the bayonet 14, so that a firm locking effect is formed between the hook 9 and the bayonet 14, further strengthening the fixed connection between the movable plate 13 and the hook 9.

[0039] This structural design ensures that the connection between the hook 9 and the movable plate 13 is more stable during the lifting process, thereby improving the safety and stability of the lifting. The design can also effectively resist the influence of external environmental factors such as vibration and wind on the connecting parts, extend the service life of the equipment, and reduce maintenance costs.

[0040] As a preferred embodiment of the present invention, a placement opening 7 is provided on the movable seat 1 for placing and positioning the connecting shell 3. One end of the connecting shell 3 is arranged in the movable seat 1 by passing through the placement opening 7, so as to ensure that the connecting shell 3 can be firmly connected to the movable seat 1. In order to enhance the stability of the connecting shell 3, a mounting side wing 8 is provided on the side of the connecting shell 3, and the mounting side wing 8 plays a role in supporting and limiting one end of the connecting shell 3.

[0041] The movable seat 1 is provided with a mounting hole 11, which is matched with the tension bolt 20 on the mounting wing 8. The mounting wing 8 limits one end of the connection housing 3 in the placement opening 7 through the tension bolt 20. After the connection housing 3 is horizontally moved to a suitable position, the mounting wing 8 is fixed to the movable seat 1 through the tension bolt 20, thereby firmly fixing the position of the connection housing 3 and ensuring that the connection housing 3 will not be displaced or shaken unnecessarily during operation.

[0042] The outer diameter of the tension bolt 20 is matched with the inner diameter of the opening of the mounting hole 11 to ensure a tight fit during the installation process. This design of the tension bolt 20 not only improves the installation accuracy, but also ensures a stable locking effect on the position of the connection housing 3, further improving the reliability and safety of the equipment during operation. In addition, the installation wing 8 can be adjusted by adjusting the tension bolt 20 to conveniently adjust the position of the connection housing 3 to meet different usage requirements.

[0043] As a preferred embodiment of the present invention, a lifting ring 18 is provided on one side of the movable seat 1 away from the connecting shell 3, and the lifting ring 18 is used to connect the lifting equipment, such as a crane or a hoist, during the lifting process. The design of the lifting ring 18 takes into account the load requirements of the equipment, and its strength and structure can withstand the vertical and horizontal forces generated during the lifting process of the equipment, ensuring the safety and stability of the lifting process.

[0044] The lifting ring 18 is made of high-strength material, has strong tensile and bending resistance, and can effectively disperse the force generated during lifting, thereby reducing the pressure on the movable seat 1 and other connecting parts. The position and fixing method of the lifting ring 18 are precisely designed so that the center of gravity of the equipment is reasonably distributed during the lifting process, avoiding the equipment from tilting or unbalanced due to uneven force.

[0045] As a preferred embodiment of the present invention, a support mechanism 16 is provided on one side of the movable seat 1 away from the connecting shell 3, and the support mechanism 16 is used to adjust the vertical height of the movable seat 1, so that the connecting shell 3 can be adjusted within different height ranges as needed. Through the support mechanism 16, the relative height between the movable seat 1 and the connecting shell 3 can be accurately controlled, and then the end of the connecting shell 3 disposed in the placement port 7 can be adjusted to reach the required vertical height.

[0046] The support mechanism 16 can be adjusted manually or automatically according to actual use requirements. For example, the support mechanism 16 can include a hydraulic device, an electric lifting system or a mechanical adjustment device to quickly and conveniently adjust the height of the connection housing 3 during the lifting or installation process. This adjustment function can ensure that the device can flexibly adapt to steel cages of different sizes and maintain a stable working state.

[0047] This height adjustment design enables the connection housing 3 to adapt to different specifications of steel cages, especially when the steel cages are of different sizes or have special requirements, it can provide better adaptability. Through precise adjustment, it is ensured that the connection housing 3 can be correctly installed in the appropriate position of the steel cage, avoiding operational difficulties or equipment damage caused by size mismatch.

[0048] In addition, the support mechanism 16 can also conveniently move the two connecting shells 3 horizontally to the middle position of the steel cage, ensuring that the two connecting shells 3 can be symmetrically connected to the steel cage. This function greatly improves the accuracy and efficiency of the operation and reduces the complexity of manual adjustment. Through this design, the adaptability, stability and operational convenience of the equipment in various working environments can be significantly improved.

[0049] As a preferred embodiment of the present invention, the support mechanism 16 includes a mounting seat 161 installed on the side of the movable seat 1, a telescopic component 162 is provided at the bottom of the mounting seat 161, a support leg 164 is installed at one end of the piston rod of the telescopic component 162, and a support side wing 163 is provided on the side of the support leg 164.

[0050] As a preferred embodiment of the present invention, movable wheels 17 are installed at the bottom of the movable seat 1 and the bottom of the supporting legs 164. When the movable seat 1 and the connecting shell 3 are pushed to move horizontally, the movable wheels 17 assist the movement of the movable seat 1, and the supporting wings 163 support the movable seat 1. When it is necessary to adjust the height of the connecting shell 3, the supporting legs 164 can be pushed by the telescopic parts 162 to adjust the height of the movable seat 1, which is flexible and convenient to use.

[0051] As a preferred embodiment of the present invention, the movable wheel 17 is provided with a foot brake.
