Description

Technical Field

[0001] This utility model relates to the field of bridle installation technology, specifically to a detachable bridle installation device. Background Technology

[0002] In the construction of multi-story and high-rise steel-concrete structures, walkways are a very common structural type. They are mostly installed under or within the steel structure and are often used for manual inspection and later maintenance of roofs, space frames, etc. The common construction method is as follows: first, install the embedded parts of the hanging columns, set up temporary supports, assemble the walkway in sections on site, then use a truck crane to lift it into place, and finally remove the temporary supports. This traditional installation method is cumbersome, involves a large amount of work, and has low construction efficiency. Moreover, the walkway is usually installed last, making truck crane operations difficult.

[0003] Traditional catwalk installation devices are mostly cantilever support structures, which have poor stress stability. In order to ensure stability and strength, these structures have increased self-weight, are relatively complex, are not easy to rotate, and lack the setting to adjust the distance between the electric hoist lifting device and the crossbeam, resulting in insufficient adaptability. Utility Model Content

[0004] The purpose of this invention is to provide a detachable catwalk installation device to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a detachable catwalk installation device, comprising: beam; The support frame assembly is placed on top of the crossbeam; At least two movable rods are rotatably connected to both sides of the support frame assembly, and an electric hoist lifting device is fixedly installed between the two movable rods on the same side of the support frame assembly. Fixing components are used to securely mount the support frame assembly onto the crossbeam; Several support rods, each of which is obliquely installed between the movable rod and the side of the crossbeam.

[0006] Using the above-mentioned detachable hoist installation device, the support base is placed on top of the crossbeam, the nut is turned and the clamping plate is pushed to clamp the crossbeam, and the support frame assembly is fixed. It can be adapted to crossbeams of different sizes. After confirming that the electric hoist lifting device is symmetrical and horizontal, the connection is checked and the lifting device is started to lift the hoist. To avoid imbalance of force, the fasteners of the support rod are loosened, the angle of the movable rod is adjusted and then tightened again. The angle of the support rod is stabilized and the clamping force of the clamping plate is enhanced.

[0007] Preferably, the support frame assembly includes two T-shaped frames, and a connecting column is horizontally fixed between the two T-shaped frames.

[0008] Preferably, both sides of the T-shaped frame are rotatably connected to movable rods.

[0009] Preferably, the fixing assembly includes two support seats that are fixedly connected to the bottom of the T-shaped frame, the support seats contact the top of the crossbeam, and at least two parallel screws are fixedly connected to the support seats. Two clamping plates are slidably connected to the screws, and nuts are threaded onto the screws to push the clamping plates so that the clamping plates contact the side of the crossbeam.

[0010] Preferably, the clamping plate corresponds to and contacts the top of the crossbeam.

[0011] Preferably, a fixing plate is fixedly connected to the clamp, the fixing plate has a number of mounting holes in the vertical direction, the movable rod has a number of holes in the length direction, and the two ends of the support rod are fixedly connected to the holes and mounting holes of the movable rod, respectively.

[0012] Preferably, the connecting column is made of H-beam steel.

[0013] Preferably, the movable rod is arc-shaped, with the arc-shaped back of the movable rod facing upwards.

[0014] Preferably, there are at least two electric hoist lifting devices, which are symmetrically distributed around the central axis of the crossbeam, and all of the electric hoist lifting devices are on the same horizontal plane.

[0015] The beneficial effects are: 1. The clamping width can be flexibly adjusted by the cooperation of screw, nut and clamping plate to adapt to different steel structure beams, without the need to prepare multiple sets of devices for beams of different specifications; on the other hand, by using the combination of the mounting holes of the fixed plate and the holes of the movable rod, the distance between the electric hoist lifting device and the beam can be precisely adjusted to meet the needs of the hoist in different installation positions under the structure. 2. The device can be quickly fixed by modular support frame components and fixing components, and the electric hoist can be used to lift the walkway instead of the truck crane. It is not limited by the construction space in the later stage of multi-story buildings, and there is no need to wait for large equipment to enter the site, thus shortening the construction cycle. 3. The electric hoist lifting devices are symmetrically distributed and on the same horizontal plane, ensuring that the support frame components are subjected to uniform force; the movable rod and the support rod cooperate to form a stable triangular load-bearing structure, replacing the traditional cantilever support and reducing the risk of swaying and tilting; in addition, the pressure transmitted by the support rod can enhance the clamping force of the clamp plate on the crossbeam, further improving the overall stability of the device and ensuring the safety of the hoist lifting operation.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] See Figures 1-2 As shown, this utility model provides a detachable catwalk installation device, including: a crossbeam 1, a support frame assembly 2, an electric hoist lifting device 6, and a fixing assembly 3. The support frame assembly 2 is placed on top of the crossbeam 1. At least two movable rods 4 are rotatably connected to both sides of the support frame assembly 2. The movable rods 4 are arc-shaped, with the arc-shaped back facing upwards. An electric hoist lifting device 6 is fixedly installed between the two movable rods 4 on the same side of the support frame assembly 2. There are at least two electric hoists 6, symmetrically distributed around the central axis of the crossbeam 1, and all electric hoists 6 are on the same horizontal plane. This arrangement ensures that the support frame assembly 2 is subjected to uniform force, allowing the catwalk to be lifted using the electric hoist lifting devices 6. The fixing assembly 3 is used to fix the support frame assembly 2 onto the crossbeam 1. Several support rods 5 are obliquely installed between the movable rods 4 and the side of the crossbeam 1.

[0021] As an optional implementation, see Figure 1 The support frame assembly 2 includes two T-shaped frames 7, with a connecting column 8 horizontally fixed between the two T-shaped frames 7. Movable rods 4 are rotatably connected to both sides of each T-shaped frame 7. The connecting column 8 is made of H-beam steel.

[0022] In this embodiment, the support frame assembly 2 consists of at least two T-shaped frames 7 and connecting columns 8. The connection points between the T-shaped frames 7 and the connecting columns 8 are connected by bolts, making disassembly convenient and easy to carry.

[0023] As an optional implementation, the fixing assembly 3 includes two support seats 9 respectively fixedly connected to the bottom of the T-shaped frame 7. The support seats 9 are in contact with the top of the crossbeam 1. At least two parallel screws 10 are fixedly connected to the support seats 9. Two clamping plates 11 are slidably connected to the screws 10. Nuts 12 are threadedly connected to the screws 10 for pushing the clamping plates 11 so that the clamping plates 11 are in contact with the side of the crossbeam 1. The clamping plates 11 correspond to and contact the top of the crossbeam 1. In this embodiment, by rotating the nut 12, the nut 12 pushes the clamping plate 11, so that the clamping plate 11 fits against the side of the crossbeam 1. The crossbeam 1 can be clamped by the cooperation of several clamping plates 11, thereby realizing the stable fixed connection of the support frame assembly 2 to the crossbeam 1. Furthermore, the fixing assembly 3 can be adapted to crossbeams 1 of different sizes.

[0024] Furthermore, a fixing plate 13 is fixedly connected to the clamping plate 11. The fixing plate 13 has several mounting holes 14 in the vertical direction. Several holes are provided on the movable rod 4 along its own length direction. The two ends of the support rod 5 are fixedly connected to the holes and mounting holes 14 of the movable rod 4, respectively. In this embodiment, the movable rod 4 has two functions. On the one hand, it can support the movable rod 4. The load-bearing method of the movable rod 4 and the support rod 5 is more stable than the traditional cantilever support structure. On the other hand, the support rod 5 can transmit the pressure of the movable rod 4 to the clamping plate 11, which helps the clamping plate 11 to clamp the crossbeam 1 more stably. By setting the fixed plate 13, several mounting holes 14 and several holes on the movable rod 4, the angle of the movable rod 4 can be adjusted, thereby adjusting the distance between the electric hoist lifting device 6 and the side of the crossbeam 1.

[0025] Using the above structure, the support seat 9 at the bottom of the T-shaped frame 7 in the support frame assembly 2 is placed stably on the top of the crossbeam 1, ensuring that the support seat 9 is completely in contact with the top surface of the crossbeam 1, providing a stable foundation for subsequent fixing; Continue to rotate the nut 12 until the clamping plate 11 is in close contact with the side and top of the crossbeam 1. Through the clamping force of multiple sets of clamping plates 11, the support frame assembly 2 is stably fixed on the crossbeam 1. The spacing of the clamping plates 11 on the screw 10 can be adjusted to adapt and fix crossbeams 1 of different specifications. The electric hoists 6 are symmetrically distributed around the central axis of the crossbeam 1, and all are on the same horizontal plane to ensure balanced force. The connection between the electric hoists 6 and the walkway is checked to ensure the hooks or connectors are secure and reliable. The power system of the electric hoists 6 is started, and the walkway is lifted using the hoist's lifting function. During lifting, the symmetrically distributed electric hoists 6 evenly distribute the weight of the walkway to the support frame assembly 2, preventing excessive force on one side from causing tilting or structural damage. Based on the required distance between the electric hoists 6 and the side of the crossbeam 1 for walkway installation, the tilt angle of the movable rod 4 is adjusted. Once the movable rod 4 reaches the target angle, one end of the support rod 5 is connected to the corresponding hole on the movable rod 4, and the other end is connected to the matching mounting hole 14 on the fixed plate 13. The fasteners are then tightened. The support rod 5 not only supports the movable rod 4 to maintain a stable angle but also transmits the pressure borne by the movable rod 4 to the clamping plate 11, further enhancing the clamping stability of the clamping plate 11 on the crossbeam 1.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
