Description

Technical Field

[0001] This utility model belongs to the field of U-shaped pendant technology, specifically relating to a U-shaped pendant for operating rooms that is easy to install. Background Technology

[0002] Operating room pendant towers are core equipment used in medical settings for the centralized suspension of medical instruments, gas delivery pipelines, and electrical wiring. In existing technologies, the basic structure of a pendant tower typically consists of a U-shaped frame assembled from beam components and corner components. A suspension bridge connecting pipe is fixedly installed at the corner of the frame, and a suspension bridge connecting plate is connected to the upper end of the suspension bridge connecting pipe. During installation, the suspension bridge connecting plate must be aligned with the pre-installed fixed brackets on the ceiling, and then the frame is rigidly fixed to the fixed brackets with bolts. During disassembly and maintenance, the fixing bolts must be removed first, and then the frame must be separated from the fixed brackets to complete the assembly and maintenance of the equipment.

[0003] In the existing installation process of the U-shaped tower crane, after the bridge connecting plate is aligned with the fixed support and before the bolts are tightened, it is necessary to manually maintain the relative alignment between the frame and the fixed support. During the disassembly process, after the fixing bolts are removed, the limiting relationship between the frame and the fixed support needs to be released by manually adjusting the positions of multiple components. This results in a large number of manual operations during the installation and disassembly process, which has a certain impact on the overall work efficiency. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a convenient-to-install operating room spiral pendant system.

[0005] To achieve the above objectives, this utility model provides a conveniently installed operating room spiral pendant tower, comprising four crossbeam components, which are connected by four corner components. Each of the four corner components has a bridge connecting pipe fixedly installed at its upper end, and each of the four bridge connecting pipes has a bridge connecting plate fixedly connected to its upper end. A limiting component for pre-positioning is provided at the center of each of the four bridge connecting plates, and the limiting component includes a cross tube that passes through and is installed at the center of each of the four bridge connecting pipes.

[0006] In the above technical solution, a drive shaft is rotatably connected to the center of the cross tube, a drive disc is fixedly connected to the upper end of the drive shaft, four extrusion blocks are fixedly connected to the outer wall of the drive disc, the lower end of the drive shaft passes through the cross tube, and an adjustment knob is fixedly connected to the lower end of the drive shaft.

[0007] In the above technical solution, four transmission rods are slidably connected to the four extrusion blocks inside the cross tube, and a transmission plate is fixedly connected to the end of each transmission rod away from the transmission disc.

[0008] In the above technical solution, a symmetrically arranged reset spring is fixedly connected to one side of the transmission plate, and an L-shaped plate is fixedly connected to the end of the reset spring away from the transmission plate. The L-shaped plate is fixedly connected to the suspension bridge connecting plate.

[0009] In the above technical solution, two clamping plates are slidably connected through the L-shaped plate, and a traction shaft is slidably connected through one side of each of the two clamping plates. The end of the traction shaft is fixedly connected to the transmission plate, and a pressing slope is opened on the upper side of the end of the clamping plate away from the traction shaft.

[0010] In the above technical solution, the end of the transmission rod near the transmission disk is designed with an arc shape, and the end of the transmission rod is offset from the extrusion block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) By setting a limiting component with an extrusion ramp and a return spring at the suspension bridge connection plate, during installation, the frame only needs to be lifted and aligned with the fixed bracket. The natural extrusion force of the fixed bracket on the extrusion ramp can trigger the card plate to automatically lock into the limiting position. There is no need for continuous manual support of the frame, which completely solves the problem of manual positioning during the installation stage. This allows the bolt tightening operation to be carried out stably and without deviation, greatly reducing the time of manual intervention during the installation process and significantly improving the installation efficiency.

[0012] (2) The disassembly process is simplified. During disassembly, only the adjustment knob needs to be rotated to drive the transmission disc and the extrusion block through the transmission shaft, which will push the transmission rod and the transmission plate to release the limit state of the clamping plate. There is no need to manually adjust multiple parts, which solves the problem of cumbersome limit release operation in the existing process. At the same time, the automatic limit during installation and the convenient release during disassembly avoid frame displacement and component damage caused by unstable manual support or improper component adjustment. It takes into account both operation efficiency and equipment safety, and meets the operating room's requirements for the convenience and stability of equipment installation and maintenance.

Detailed Implementation To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-5 The illustrated operating room spiral pendant includes four crossbeam components 1, which are connected by four corner components 2. Each corner component 2 has a fixedly installed bridge connecting pipe 3 at its upper end, and each bridge connecting pipe 3 has a fixedly connected bridge connecting plate 4 at its upper end. Each bridge connecting plate 4 has a limiting component for pre-positioning at its center, and the limiting component includes a cross tube 5 that passes through and is installed at the center of each of the four bridge connecting pipes 3. A drive shaft 6 is rotatably connected to the center of the cross tube 5. A drive disc 7 is fixedly connected to the upper end of the drive shaft 6. Four extrusion blocks 8 are fixedly connected to the outer wall of the drive disc 7. The lower end of the drive shaft 6 passes through the cross tube 5, and an adjustment knob 9 is fixedly connected to the lower end of the drive shaft 6. Four drive rods 10 are slidably connected to the four extrusion blocks 8 inside the cross tube 5. A drive plate 11 is fixedly connected to the end of each drive rod 10 away from the drive disc 7. A symmetrically arranged return spring 12 is fixedly connected to one side of the drive plate 11. An L-shaped plate 13 is fixedly connected to the end of the return spring 12 away from the drive plate 11. The L-shaped plate 13 is fixedly connected to the suspension bridge connecting plate 4. Two clamping plates 14 are slidably connected through the L-shaped plate 13. A traction shaft 15 is slidably connected through one side of each clamping plate 14. The end of the traction shaft 15 is fixedly connected to the drive plate 11. An extrusion slope 16 is opened on the upper side of the end of the clamping plate 14 away from the traction shaft 15. The end of the drive rod 10 near the drive disc 7 has an arc-shaped structure design. The end of the drive rod 10 is staggered from the extrusion block 8.

[0016] Working principle: Before installation, the U-shaped tower foundation frame, which is composed of four crossbeam components 1 and four corner components 2, is manually lifted. During the lifting process, ensure that the suspension bridge connecting pipes 3 fixed at the upper end of the four corner components 2 are lifted synchronously, thereby driving the suspension bridge connecting plate 4 fixed at the upper end of the suspension bridge connecting pipe 3 to align with the fixed bracket to be installed on the ceiling. At this time, it is necessary to ensure that the L-shaped plate 13 fixed on the suspension bridge connecting plate 4 and the sliding clamping plate 14 on the L-shaped plate 13 correspond to the position of the limiting hole of the fixed bracket, in preparation for subsequent limiting.

[0017] During installation, the plate is slowly lifted upwards. The lower end of the ceiling mounting bracket will contact the pressing slope 16 on the upper side of the end of the clamping plate 14 away from the traction shaft 15, generating a downward pressing force on the pressing slope 16. This pressing force pushes the clamping plate 14 to slide away from the cross tube 5. Since the end of the traction shaft 15, which is slidably connected through one side of the clamping plate 14, is fixed to the transmission plate 11, the sliding of the clamping plate 14 will drive the transmission plate 11 to move synchronously towards the cross tube 5. When the transmission plate 11 moves, it will stretch the return spring 12 symmetrically arranged on one side, and the return spring 12 will enter the stretched state.

[0018] Continue to raise the top frame to the preset installation height. When the clamping plate 14 slides directly above the limiting hole of the ceiling fixing bracket, the pressing force of the fixing bracket on the pressing slope 16 disappears. The return spring 12 releases its contraction force and pushes the transmission plate 11 in the opposite direction to return to the position closer to the cross tube 5. The return of the transmission plate 11 drives the clamping plate 14 to slide along the through hole of the L-shaped plate 13 through the traction shaft 15, so that the clamping plate 14 is inserted into the upper end of the fixing bracket, completing the limiting and fixing of the U-shaped tower. At this time, there is no need for manual support of the frame. Bolts can be directly driven into the connection position between the crossbeam component 1, the corner component 2 and the fixing bracket to ensure that the tower is installed stably.

[0019] The initial power is the pressure exerted by the ceiling-mounted bracket on the inclined surface 16. The power is transmitted through the traction shaft 15 to the clamping plate 14, the transmission plate 11, and the return spring 12. Finally, the clamping plate 14 is inserted into the upper end of the fixed bracket. This not only avoids the swaying and displacement of the crane tower during installation, but also eliminates the need for manual support, ensuring the safety and efficiency of the bolt installation process.

[0020] During disassembly, first use a wrench to remove the fixing bolts driven in during installation, releasing the rigid connection between the crossbeam component 1, the corner component 2, and the ceiling fixing bracket; then manually hold the adjustment knob 9 and rotate it clockwise or counterclockwise; the rotation of the adjustment knob 9 drives the drive shaft 6 to rotate synchronously along the central rotating hole of the cross tube 5, the rotation of the drive shaft 6 drives the drive disc 7 to rotate synchronously, and the four pressing blocks 8 fixed on the outer wall of the drive disc 7 rotate with the drive disc 7, contacting the arc-shaped end of the corresponding drive rod 10 near the drive disc 7 inside the cross tube 5; the pressing blocks 8 generate a pressing force on the drive rod 10 in the direction away from the drive shaft 6, pushing the drive rod 10 to slide along the inner wall of the cross tube 5; the end of the drive rod 10 away from the drive disc 7 is fixed to the drive plate 11, and the sliding of the drive rod 10 drives the drive plate 11 to move away from the cross tube 5; the movement of the drive plate 11 pulls the clamping plate 14 along the L-shaped plate 13 towards the cross tube 5 through the traction shaft 15, so that the clamping plate 14 is removed from the upper end of the ceiling fixing bracket, completely releasing the limiting state of the crane tower.

[0021] After the limit is released, the crane frame, consisting of the crossbeam component 1, corner component 2, suspension bridge connecting pipe 3, and suspension bridge connecting plate 4, can be lifted manually and detached from the ceiling fixed support to complete the disassembly operation. No manual assistance is required throughout the process, which simplifies the disassembly steps and prevents the crane from accidentally falling off during disassembly, ensuring operational safety.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
