Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, specifically to a pile foundation installation steel cage suspension positioning frame. Background Technology

[0002] The rebar cage suspension positioning frame for pile foundation installation is a key tool in pile foundation construction. It is a rigid frame welded from steel profiles and other materials, including positioning slots and fasteners. It can accurately fix the position of the rebar cage, prevent it from shifting or floating during pouring, ensure the thickness of the rebar protective layer and the verticality of the pile foundation, improve construction quality and efficiency, and is suitable for various pile foundation projects.

[0003] Chinese patent discloses a pile foundation rebar cage positioning device (authorization announcement number CN217352486U), including a gantry frame. The gantry frame has casters at its bottom, a lifting rod at its center, a positioning mounting frame at its lower end, a positioning telescopic mechanism on the mounting frame, and a hook device at its lower end. This patented technology controls a motor to rotate a threaded rod, adjusting the position of the threaded sleeve, which in turn moves the tie rod and crossbar upwards or downwards to adjust the position of the hook device. This allows for the hooking of rebar cages of different sizes. The position of the lifting rod or gantry frame determines whether the rebar cage is centered on the pile foundation. Moving the gantry frame allows for accurate adjustment of the rebar cage's position, flexibly adjusting its size for easy positioning and installation of different types of rebar cages. It also allows for flexible assembly and disassembly of the rebar cage, making it convenient, time-saving, and labor-saving. However, this patent relies on manual adjustment of the hook position, requiring repeated manual alignment and operation, which is not only time-consuming and labor-intensive but also poses a risk of accidental injury in high-altitude hoisting scenarios due to the significant human intervention, indicating insufficient safety.

[0004] Therefore, this utility model provides a suspension positioning frame for the steel cage of pile foundation installation to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pile foundation installation steel cage suspension positioning frame includes a steel cage, a crossbeam installed on the top of the steel cage, two sets of connecting sleeves fixedly connected to the outer wall of the crossbeam, a chain for transmitting lifting force hinged to the top of each of the two sets of connecting sleeves, a connecting lug hinged to the top of the chain, and a pulley hook hinged to the bottom of each of the two sets of connecting sleeves. A sling for connecting and fixing the steel cage is slidably connected to the inner cavity of the pulley hook, and the sling is hinged to the steel cage.

[0008] The top of the connecting lug is hinged to a lifting hook for lifting the steel cage, and the lifting hook is hinged to the connecting lug to drive the steel cage to move up and down.

A locking block is fixedly connected to the top of the connecting rod. The slider is located on the bottom surface of the locking block, and the two are locked together to achieve automatic docking of the crane and the lifting hook.

[0010] The connecting rod and the locking block are fixedly connected by a fixed shaft. The outer wall of the fixed shaft is slidably fitted with a reset block, which is used to break the locking limit between the locking block and the slider, so as to realize the automatic separation and reset of the crane and the lifting hook.

[0011] As a further embodiment of this utility model, magnetic rings for assisting in the precise docking of the docking components are fixedly installed at the bottom end of the moving tube and the top end of the card block, and the two sets of magnetic rings are magnetically connected.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-2 In this embodiment of the utility model, the pile foundation installation steel cage suspension positioning frame includes a steel cage 1, a crossbeam 2 installed above the steel cage 1, two sets of connecting sleeves 3 are fixedly connected to the outer wall of the crossbeam 2 by bolts, the top of the two sets of connecting sleeves 3 are hinged to a chain 4 for transmitting lifting force, the top of the chain 4 is hinged to a connecting lug 5, the bottom of the two sets of connecting sleeves 3 are hinged to a pulley hook 6, the inner cavity of the pulley hook 6 is slidably connected to a sling 7 for connecting and fixing the steel cage 1, and the sling 7 is hinged to the steel cage 1.

[0029] The top of the connecting lug 5 is hinged with a lifting hook 8 for lifting the steel cage 1, and the lifting hook 8 is hinged with the connecting lug 5 to drive the steel cage 1 to move up and down. The top of the lifting hook 8 is fixedly connected with a docking component 9 for realizing automatic docking and lifting. The bottom outer wall of the sling 7 is fixedly fitted with a reinforcement component 10 for enhancing the connection effect with the steel cage 1.

[0030] Specifically, the inner cavity of the crossbeam 2 has multiple adjustment holes, and the position of the connecting sleeve 3 on the crossbeam 2 is adjusted and fixed by bolts to flexibly adjust the spacing, adapt to different specifications of steel cage 1, improve versatility, and at the same time, fine-tuning the position of the connecting sleeve 3 can optimize the distribution of lifting force, ensure the balance and stability of the steel cage 1 during lifting, avoid tilting and deformation caused by misalignment of lifting points, and help to accurately lift and control the quality of pile foundation construction. In addition, there are two sets of chains 4 and slings 7, which are symmetrically and evenly distributed between the two sets to balance the load and stabilize the lifting, so that the lifting force is evenly distributed, avoid deformation of the crossbeam 2 due to uneven force, ensure the stability of the steel cage 1 during lifting, prevent tilting and shaking, improve the safety and accuracy of lifting, and adapt to the strict requirements of pile foundation construction on the installation position of the steel cage 1.

[0031] Please see Figure 3 , Figure 4 , Figure 5The docking assembly 9 includes a connecting rod 901, which is located at the top of the lifting hook 8. A moving tube 902 is slidably sleeved above the connecting rod 901. The top of the moving tube 902 is rotatably connected to a crane 903 for providing lifting power via a pin. A slider 904 is slidably connected to the inner cavity of the moving tube 902. A locking block 905 is fixedly connected to the top of the connecting rod 901. The slider 904 is located on the bottom surface of the locking block 905, and the two are locked together to realize the automatic docking of the crane 903 and the lifting hook 8.

[0032] The connecting rod 901 and the locking block 905 are fixedly connected by a fixed shaft 906. The outer wall of the fixed shaft 906 is slidably fitted with a reset block 907, which is used to break the locking limit between the locking block 905 and the slider 904, so as to realize the automatic separation and reset of the crane 903 and the lifting hook 8.

[0033] Specifically, both the locking block 905 and the reset block 907 are designed as frustum structures, and the angles of their outer wall inclination surfaces are set in opposite directions. Meanwhile, one side of the slider 904 has an inclined surface that fits against the outer wall of the locking block 905 (see details for reference). Figure 4 , Figure 5 );

[0034] More specifically, the inner cavity of the moving tube 902 is provided with a groove for providing sliding for the slider 904, and the slider 904 is located in the groove. The side of the slider 904 away from the block 905 is fixedly connected to the moving shaft 909, and the outer wall of the moving shaft 909 is fitted with a locking and limiting spring 908 for reinforcing the locking block 905 and the slider 904. The end of the moving shaft 909 away from the slider 904 passes through the moving tube 902 and is fixedly connected with a limiting plate for preventing slippage.

[0035] The bottom end of the moving tube 902 and the top end of the locking block 905 are both fixedly installed with magnetic rings 910 to assist in the precise docking of the docking assembly 9. The two sets of magnetic rings 910 are magnetically connected. The inner wall of the through hole of the connecting lug 5 is embedded with an anti-slip silicone pad. The size of the through hole is precisely matched with the outer diameter of the lifting hook 8. The elastic friction resistance of the silicone pad ensures that the lifting hook 8 and the connecting lug 5 maintain coaxiality when they are hinged. Thus, during the automatic docking process between the crane 903 and the lifting hook 8, the connecting rod 901 is kept in a stable upright state through the dual action of magnetic pre-positioning and mechanical friction, avoiding the problem of jamming failure or uneven force due to docking misalignment.

[0036] Please see Figure 3 , Figure 4 , Figure 5 The two sides of the moving tube 902 are rotatably connected by pins to a clamping frame 111 for strengthening the connection between the crane 903 and the hook 8. The bottom end of the clamping frame 111 is fixedly connected to a clamping ring 112, and the clamping ring 112 is in contact with the outer wall of the connecting rod 901.

[0037] Specifically, a moving plate 113 is slidably connected to the inner cavity of the moving tube 902. A toothed plate 114 for controlling the rotation of the clamping frame 111 is fixedly connected to the top of the moving plate 113. Gears 115 for driving the clamping frame 111 to rotate are meshed on both sides of the toothed plate 114. The gears 115 are rotatably connected to the clamping frame 111 through a pin.

[0038] More specifically, a thrust spring 116 is fixedly connected to the bottom surface of the movable plate 113, and an abutment plate 117 is fixedly connected to the bottom end of the thrust spring 116, and the abutment plate 117 is in contact with the locking block 905.

[0039] More specifically, there are two sets of clamping frames 111, and the bottom of the outer wall of the two sets of clamping frames 111 are respectively fixedly installed with racks 118 and toothed rings 119 through connectors. The inner cavity of rack 118 has a locking groove. The side of toothed ring 119 near clamping frame 111 has a locking tongue 110 that rotates through a pin. The inner cavity of connecting rod 901 has a through groove. When moving tube 902 moves down, it gradually squeezes the thrust spring 116, thereby pushing moving plate 113 and toothed plate 114 to move up, driving gear 115 to rotate, driving the two sets of clamping frames 111 to rotate accordingly, so that the bottom ends of the two sets of clamping frames 111 gradually insert into the through groove and move closer to each other, so that rack 118 and toothed ring 119 come into contact, thereby driving locking tongue 110 to rotate and insert into locking groove, thereby further restricting docking component 9 and preventing accidental detachment.

[0040] Please see Figure 2 , Figure 6 The reinforcement component 10 includes a rope clamp 101, which is sleeved on the bottom of the outer wall of the sling 7 and is used to prevent the lifting point between the sling 7 and the steel cage 1 from loosening and slipping, ensuring the tightness and reliability of the connection between the two. A connecting seat 102 is connected to one side of the rope clamp 101, and the connecting seat 102 is passed through one end of the rope clamp 101. A fastening bolt 103 is threaded on its outer wall, and the fastening bolt 103 is used to limit the loosening and displacement of the connecting seat 102 relative to the rope clamp 101.

[0041] Specifically, the bottom end of the sling 7 is bent into a circular shape as the attachment point to the lifting point of the steel cage 1. The rope clamp 101 adopts a U-shaped hook design. The circular segment formed by the bending of the sling 7 is limited within the U-shaped groove of the rope clamp 101. The clamping action of the rope clamp 101 enhances the anti-detachment ability of the circular attachment structure of the sling 7. Combined with the locking of the connecting seat 102 and the fastening bolt 103, the overall stability of the connection between the sling 7 and the steel cage 1 is further improved, avoiding the risk of the lifting point falling off due to vibration and load impact during construction.

[0042] The working principle of this utility model is as follows:

[0043] When using this utility model, firstly, the position of the connecting sleeve 3 is adjusted by bolts through the adjustment hole on the crossbeam 2 to match the spacing of the lifting points of the steel cage 1. Then, the bottom end of the sling 7 is bent into a ring, put into the U-shaped groove of the rope clamp 101, and after the connecting seat 102 is inserted, the fastening bolt 103 is tightened to complete the anti-detachment reinforcement of the sling 7 and the lifting points of the steel cage 1, and enhance the connection stability. After manually hanging the lifting hook 8 on the connecting lug 5, the operator stays away from the steel cage 1 to avoid accidental danger.

[0044] As the crane 903 descends, the moving tube 902 slides down along the connecting rod 901. The bottom end of the moving tube 902 attracts the magnetic ring 910 at the top of the locking block 905. The auxiliary docking component 9 is precisely aligned. The moving tube 902 continues to slide down, and the slider 904 slides along the inner groove of the moving tube 902. Because the locking block 905 is a frustum structure, the slider 904 forms a wedge-shaped engagement with the locking block 905 under the elastic force of the limiting spring 908, thus realizing the initial automatic docking of the crane 903 and the lifting hook 8.

[0045] Simultaneously, when the moving tube 902 moves downward, it compresses the thrust spring 116, pushing the moving plate 113 upward, which in turn drives the toothed plate 114 upward. Through the gear 115, the clamping frame 111 rotates around the pin shaft, allowing the clamping ring 112 to grip the connecting rod 901, thus initially strengthening the connection. Furthermore, the bottom end of the clamping frame 111 is inserted into the slot of the connecting rod 901. The racks 118 of the two sets of clamping frames 111 mesh with the toothed rings 119, driving the locking tongue 110 to rotate and insert into the locking groove, forming a secondary mechanical lock to prevent accidental dislodgement.

[0046] Then the crane 903 moves upward and transmits the lifting force through the chain 4, connecting lug 5, and lifting hook 8. The lifting force is then transmitted through the docking assembly 9 to drive the steel cage 1 to move smoothly. The load is balanced by the two symmetrically distributed sets of chains 4 and slings 7, which prevents the crossbeam 2 from deforming due to uneven stress and ensures the stability of the steel cage 1, thus meeting the accuracy requirements of the installation position for pile foundation construction.

[0047] After the final hoisting is completed, the hoist 903 is driven to move downwards, and the slider 904 moves downwards along the reset block 907. When the limit spring 908 pushes, the slider 904 comes into contact with the reset block 907. Then, the hoist 903 is controlled to move upwards, which in turn drives the reset block 907 to engage with the locking block 905, so that the slider 904 can move upwards along the locking block 905. This releases the restriction of the locking block 905 on the slider 904. At the same time, the thrust spring 116 resets and drives the moving plate 113 to move downwards. The toothed plate 114 and the gear 115 work together to open the clamping frame 111 and disengage the locking tongue 110 from the locking groove, realizing the automatic separation of the hoist 903 and the lifting hook 8, and completing the operation cycle.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
