Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an anti-tilting steel structure hoisting frame. Background Technology

[0002] A hoisting frame is a structural device specifically designed for lifting, moving, installing, or dismantling large and heavy equipment, components, and heavy objects in engineering operations. By integrating a load-bearing body, a lifting drive system, and a safety protection mechanism, it enables the spatial displacement of heavy objects under controlled conditions. Its core function is to solve the problem of handling heavy loads that cannot be accomplished by manpower or conventional equipment, ensuring operational efficiency and safety.

[0003] Lifting frames significantly improve the efficiency of heavy object handling through mechanical transmission, replacing traditional multi-person collaboration with single or double-person operation, increasing work efficiency by dozens of times and reducing labor costs. However, due to insufficient frame rigidity and simplified support structure, lifting frames are prone to frame swaying, slight deformation, or even overall overturning when subjected to eccentric loads or close to the rated lifting capacity. Existing technology uses in-plane diagonal bracing or scissor bracing to prevent frame instability or local deformation. However, to ensure stability under heavy loads, the design uses wide support spacing, which occupies a large space when transferring under no-load conditions, making it difficult to pass through narrow construction sites. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-tilting steel structure hoisting frame, which aims to improve the problem that the existing technology, which is designed with wide support spacing to ensure stability under heavy load, occupies a lot of space when transferring under no-load load, making it difficult to pass through narrow construction sites.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-tilting steel structure hoisting frame, including a support leg, a support frame provided on the top of the support leg, an anti-tilting mechanism provided inside the support leg to prevent the support leg from tilting, and a lifting mechanism provided inside the support leg to adjust the height of the support frame.

[0006] The anti-tilt mechanism includes a connecting block 1, which is fixedly connected to the upper middle part of the front and rear sides of the outer wall of the support leg. A support rod 1 is rotatably connected to the outer wall of the connecting block 1, and a support rod 2 is slidably connected to the outer wall of the support rod 1. A connecting block 2 is rotatably connected to the bottom wall of the support rod 2. Square grooves are provided on both the front and rear sides of the outer wall of the support leg. A movable seat is provided inside the square groove. The bottom wall of the connecting block 2 is fixedly connected to the top wall of the movable seat. An adjustment component is provided on the outer wall of the support leg.

[0007] As a further description of the above technical solution:

[0008] The adjustment assembly includes a knob disposed on the outer wall of the support leg. A worm gear is fixedly connected to the outer wall of the knob. A bidirectional threaded rod is rotatably connected inside the support leg. A worm wheel is fixedly connected to the middle of the outer wall of the bidirectional threaded rod. The worm wheel meshes with the worm gear. A threaded groove is formed on the outer wall of the movable seat. The threaded groove is threadedly connected to the bidirectional threaded rod.

[0009] As a further description of the above technical solution:

[0010] The lifting mechanism includes a limiting block, which is fixedly connected to the inner wall of the support leg. A limiting groove is formed on the outer wall of the support frame. The limiting block is slidably connected to the limiting groove. A driving component is provided on the outer wall of the support leg.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes a motor, which is fixedly connected to the outer wall of the support leg. A universal joint is fixedly connected to the output end of the motor, and a lead screw is fixedly connected to the end of the universal joint. A threaded groove is provided on the bottom wall of the support frame, and the threaded groove is threadedly connected to the lead screw.

[0013] As a further description of the above technical solution:

[0014] The movable seat is slidably connected to the square groove, and the worm gear is rotatably connected inside the support leg.

[0015] As a further description of the above technical solution:

[0016] The support leg is slidably connected to the support frame, and the universal joint is rotatably connected inside the support leg.

[0017] As a further description of the above technical solution:

[0018] The support leg is equipped with casters on both the front and rear sides of its bottom wall, and brakes are installed on the outer walls of the casters.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the support frame is equipped with a lifting device, and the bottom wall of the lifting device is equipped with a hook.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the knob drives the worm to rotate, and the worm meshes with the worm wheel on the double-threaded rod, causing the double-threaded rod to rotate. This drives the movable seat in the square groove to slide back and forth synchronously. The movable seat drives the connecting block two to move, causing the support rod one to extend and retract within the support rod two. The triangular structure enhances the stability of the support leg, and the extension and angle adjustment range of the support rod can be controlled as needed. During heavy hoisting, the support point can be expanded to enhance stability, and during unloaded transfer, the support rod can be retracted to reduce the space occupied, thus adapting to various construction environments.

[0023] 2. In this utility model, the motor output end drives the lead screw to rotate through the universal joint. Because the lead screw rotates in the threaded groove 2 on the bottom wall of the support frame, the limiting groove outside the support frame slides on the limiting block inside the support leg. This limits the support frame to only rise and fall along the axial direction, avoiding its deviation and tilting, thereby ensuring that the height adjustment is stable and safe.

[0031] 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.

[0032] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: an anti-tilting steel structure hoisting frame, including a support leg 1, a support frame 2 provided on the top of the support leg 1, an anti-tilting mechanism 3 provided inside the support leg 1, the anti-tilting mechanism 3 is used to prevent the support leg 1 from tilting, and a lifting mechanism 4 provided inside the support leg 1, the lifting mechanism 4 is used to adjust the height of the support frame 2.

[0033] The anti-tilt mechanism 3 includes a first connecting block 301, which is fixedly connected to the upper middle part of the front and rear sides of the outer wall of the support leg 1. The outer wall of the first connecting block 301 is rotatably connected to a first support rod 302. The outer wall of the first support rod 302 is slidably connected to a second support rod 303. The bottom wall of the second support rod 303 is rotatably connected to a second connecting block 304. Square grooves 305 are provided on both the front and rear sides of the outer wall of the support leg 1. A movable seat 306 is provided inside the square groove 305. The bottom wall of the second connecting block 304 is fixedly connected to the top wall of the movable seat 306. An adjustment component 307 is provided on the outer wall of the support leg 1.

[0034] The adjustment assembly 307 includes a knob 3071, which is disposed on the outer wall of the support leg 1. A worm gear 3072 is fixedly connected to the outer wall of the knob 3071. A bidirectional threaded rod 3073 is rotatably connected inside the support leg 1. A worm wheel 3074 is fixedly connected to the middle of the outer wall of the bidirectional threaded rod 3073. The worm wheel 3074 is meshed with the worm gear 3072. A threaded groove 3075 is opened on the outer wall of the movable seat 306. The threaded groove 3075 is threadedly connected to the bidirectional threaded rod 3073. The movable seat 306 is slidably connected to the square groove 305. The worm gear 3072 is rotatably connected inside the support leg 1.

[0035] Specifically, rotating knob 3071 causes worm gear 3072 to rotate. Worm gear 3072 meshes with worm wheel 3074 on double-threaded rod 3073, causing double-threaded rod 3073 to rotate. Driven by double-threaded rod 3073, movable seat 306 in square groove 305 slides back and forth synchronously. Movable seat 306 drives connecting block 304 to move, causing support rod 1 302 to extend and retract within support rod 2 303. The triangular structure enhances the stability of support leg 1, and the extension and angle adjustment range of support rod can be controlled as needed. During heavy lifting operations, the support point can be extended outward to enhance stability; during unloaded transfer, the support rod can be retracted to reduce space occupation, thus adapting to various construction environments.

[0036] Reference Figure 2 , Figure 3 and Figure 5 The lifting mechanism 4 includes a limiting block 401, which is fixedly connected to the inner wall of the support leg 1. A limiting groove 402 is opened on the outer wall of the support frame 2. The limiting block 401 is slidably connected to the limiting groove 402. A drive assembly 403 is provided on the outer wall of the support leg 1.

[0037] The drive assembly 403 includes a motor 4031, model MSME102G1V. Its working principle is that when DC current is applied to the armature winding, the current is subjected to Ampere force in the magnetic field. Under the action of force, the armature winding drives the rotor to rotate. However, due to the cooperation of the commutator and brushes, the current direction in the winding will automatically reverse whenever the rotor rotates half a revolution, ensuring that the rotor is continuously subjected to torque in the same direction and realizing continuous rotation. The motor 4031 is fixedly connected to the outer wall of the support leg 1. The output end of the motor 4031 is fixedly connected to a universal joint 4032. The end of the universal joint 4032 is fixedly connected to a lead screw 4033. The bottom wall of the support frame 2 is provided with a threaded groove 4034. The threaded groove 4034 is threadedly connected to the lead screw 4033. The support leg 1 is slidably connected to the support frame 2. The universal joint 4032 is rotatably connected inside the support leg 1.

[0038] Specifically, the motor 4031 is started, and the output end of the motor 4031 drives the lead screw 4033 to rotate via the universal joint 4032. The lead screw 4033 rotates in the threaded groove 4034 on the bottom wall of the support frame 2, causing the limiting groove 402 outside the support frame 2 to slide on the limiting block 401 inside the support leg 1. This limits the support frame 2 to only perform axial lifting and lowering movements, preventing it from deviating or tilting, thereby ensuring that the height adjustment process is smooth and safe.

[0039] Reference Figure 1 and Figure 2The support leg 1 is equipped with casters 5 on both the front and rear sides of its bottom wall. The casters 5 are equipped with brakes 6 on their outer walls. The support frame 2 is equipped with a lifting device 7 on its outer wall. The lifting device 7 drives the internal transmission components through the power system, which in turn drives the hook 8 to slowly lift the heavy object off the ground. The power is then adjusted as needed to achieve the lifting and precise suspension of the heavy object. The bottom wall of the lifting device 7 is equipped with a hook 8.

[0040] Specifically, the casters 5 can be adjusted in any direction without the need for manual handling of the entire structure, greatly reducing the difficulty of transferring the hoisting frame between different work areas. The brake 6 can lock the rolling of the casters 5. The lifting device 7 drives the internal transmission components through the power system, and drives the hook 8 upward through the steel cable and chain transmission components. The hook 8 ensures that the heavy object is stably connected during the hoisting process and prevents it from falling off.

[0041] Working principle: Rotating knob 3071 drives worm gear 3072 to rotate. Worm gear 3072 meshes with worm wheel 3074 on double-threaded rod 3073, causing double-threaded rod 3073 to rotate. Simultaneously, the moving seat 306 in the drive square groove 305 of double-threaded rod 3073 slides back and forth. The moving seat 306 drives connecting block 2 304 to move, causing support rod 1 302 to extend and retract within support rod 2 303. The triangular structure enhances the stability of support leg 1. The extension and angle adjustment range of the support rod can be controlled as needed. During heavy lifting, the support point can be expanded to enhance stability, and the support rod can be retracted during unloaded transfer to reduce space occupation, thus adapting to various construction environments.

[0042] When the motor 4031 is started, the output end of the motor 4031 drives the lead screw 4033 to rotate through the universal joint 4032. Since the lead screw 4033 rotates in the threaded groove 4034 on the bottom wall of the support frame 2, the limiting groove 402 outside the support frame 2 slides on the limiting block 401 inside the support leg 1, which limits the support frame 2 to only rise and fall along the axial direction, avoids deviation and tilting, and ensures that the height adjustment is stable and safe.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
