Description

Technical Field

[0001] The utility model relates to the technical field of cable bridge lifting, in particular to a lifter for installing a cable bridge. Background Art

[0002] In many fields such as modern buildings, industrial facilities and power engineering, cable trays, as an important cable laying support structure, are widely used to ensure the orderly laying and safe operation of various cables. The installation process of cable trays involves accurately, efficiently and safely lifting the trays from the ground or a lower position to the predetermined installation height and position. This link has a vital impact on the progress, quality and safety of the entire cable laying project. In order to meet the needs of cable tray installation, a cable tray installation hoist has come into being. This hoist is designed to achieve stable lifting operation of the cable tray through a specific mechanical structure and technical principles, thereby assisting construction workers to complete the installation of the tray more conveniently and accurately, playing a key role in improving installation efficiency, reducing labor intensity and ensuring construction safety.

[0003] In existing cable tray installation projects, commonly used lifting methods mainly rely on some relatively traditional mechanical structures. The most common one is a combination of a manual hoist and a simple hanger. The manual hoist serves as the main lifting power source. The operator manually rotates the sprocket to drive the chain on the sprocket to retract or extend, thereby realizing the lifting or lowering of the cable tray by the hook connected to the chain. The simple hanger mainly plays a supporting and guiding role. It is usually welded from metal rods to form a relatively stable frame structure. A crossbeam for hanging the manual hoist is set on the top of the hanger to limit the shaking range of the hook and the cable tray during the lifting process to a certain extent, so that the cable tray moves as much as possible in the predetermined vertical direction.

[0004] However, there are some problems to be solved in the existing cable tray installation and lifting technology. Traditional lifting methods mostly use fixed-position electric hoists or manual hoists and other equipment to lift the cable tray. Once these equipment are installed, their lifting positions are relatively fixed. When facing large installation sites, such as large industrial plants, vast substations and other places, the laying paths of cable trays are usually distributed in different horizontal areas, and they need to be lifted and installed at multiple horizontal positions. However, the existing fixed-position lifting equipment is difficult to flexibly adjust according to the actual installation requirements of the cable tray in different horizontal areas. Each time a cable tray is to be lifted at a different position, it often takes a lot of time and manpower to reset the position of the lifting equipment, which not only leads to low installation efficiency, but also frequent position adjustments can easily result in inaccurate lifting positions, which in turn affects the installation accuracy of the cable tray. For this reason, a cable tray installation hoist is proposed to solve the above problems. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a cable tray installation lifter, including a support frame 1, which is the basic frame of the entire device and plays a supporting and fixing role. A crossbeam 2 is fixedly connected to the inside of the support frame 1. The crossbeam 2 serves as the main load-bearing structure and supports the movement of the sliding assembly. The crossbeam 2 not only has to bear the heavy load of the lifter, but also needs to provide a track for the smooth movement of the sliding assembly. A sliding assembly is provided inside the crossbeam 2, which is used to cooperate with the operator for flexible adjustment during work.

[0036] The sliding assembly includes a support rod 3, which cooperates with the track inside the beam 2 through a sliding connection and can slide flexibly inside the beam 2, thereby realizing precise adjustment of the position of the cable tray. The support rod 3 is slidably connected to the inside of the beam 2. A slide groove 4 is provided inside the support rod 3. The slide groove 4 not only provides a track for the movement of the pulley 6, but also ensures that the pulley 6 can slide stably along the set path during the lifting process. A limit column 5 is fixedly connected to the inside of the support rod 3. The main function of the limit column 5 is to prevent the sliding assembly from excessive movement or loss of control during operation. To ensure that its sliding process in the beam 2 is stable and controlled, the support rod 3 is internally slidably connected to a pulley 6, which not only ensures the smoothness of the entire lifting process, but also reduces wear and instability in operation through its close cooperation with the slide 4. The pulley 6 slides inside the slide 4, and the bottom of the pulley 6 is fixedly connected to a connecting frame 7, and the bottom of the connecting frame 7 is fixedly connected to a crane 8, whose function is to provide a power source and lift the cable tray through a hook connection assembly. A hook connection assembly is provided at the connection end of the crane 8, and the hook connection assembly is used to drive the cable tray to lift.

[0037] Specifically, a plurality of cables are usually laid in the cable bridge, and these cables will branch out at different positions to connect to various specific electrical equipment. When branch cable connections need to be made, the bridge needs to be moved horizontally to the corresponding branch point position. First, the operator places the device at a suitable construction position and places the bridge to be transported on the surface of the support plate 10. The support plate 10 plays a role of bearing and supporting, providing a solid foundation for subsequent transportation operations. Next, through the connection end of the crane 8, the crane 8 is used to drive the support plate 10, and the mechanical power of the crane 8 is used to realize fully automatic transportation. The crane 8 can flexibly adjust the position of the support plate 10, so that the bridge can be accurately transported to the specified position. In this process, the operator can directly pull the support rod 3 It is made to slide inside the crossbeam 2 to flexibly adjust the transportation position according to the construction conditions or the needs of the operator. The crossbeam 2 serves as a supporting structure, carrying the sliding component support rod 3, allowing it to slide freely along a specific track inside the crossbeam 2, thereby realizing precise control of transportation. At the same time, in order to further improve the flexibility and accuracy of transportation, the slide groove 4 is arranged inside the support rod 3. The slide groove 4 guides the pulley 6 to slide inside the slide groove 4, thereby realizing synchronous adjustment of the position of the crane 8. The movement of the pulley 6 is closely coordinated with the adjustment of the crane 8, thereby ensuring that the device can accurately adjust the position of the crane 8 as needed during operation, so that the entire device shows higher flexibility and adjustability in the bridge frame transportation operation, thereby effectively completing the bridge frame transportation task, and the operation is simple, accurate and efficient.

[0038] Reference Figure 5 - Figure 6The hook connection assembly includes a connecting buckle 9 and a support plate 10. The connecting buckle 9 is slidably connected to the connecting end of the crane 8. The connecting end of the crane 8 is a standardized interface for matching with the sling system. The connecting buckle 9 adopts a sliding structure, which enables it to be adjusted in position as needed on the connecting end of the crane 8, thereby facilitating the lifting and lowering and angle adjustment of the hook. The support plate 10 is fixedly connected to the bottom of the connecting buckle 9. The support plate 10 adopts a square plate design. Its main function is to provide stable support. A connecting rod 11 is fixedly connected to the inside of the support plate 10. It is designed as a long metal rod and is made of high-strength material. The function of the connecting rod 11 is to connect to the support plate 10. One side of the connecting rod 11 It is fixedly connected with a load-bearing frame 12, which is usually composed of multiple support members and adopts a reinforced design. It can withstand the huge pressure from the lifting load and disperse the stress of the load to avoid local excessive force. The upper surface of the load-bearing frame 12 is fixedly connected with a slide rail 13. The slide rail 13 has two main functions: one is to provide a stable guiding effect, and the other is to ensure that the sliding rod 15 can slide smoothly. A second slide groove 14 is provided inside the slide rail 13. The size and shape of the second slide groove 14 match the shape of the sliding rod 15 to ensure that the sliding rod 15 can move smoothly in the slide rail 13 without getting stuck or deflected. The slide rail 13 is slidably connected with the sliding rod 15, and the sliding rod 15 slides inside the second slide groove 14.

[0039] Specifically, when the cable tray needs to be quickly fixed to prevent it from moving and deviating during the lifting process, the output end of the electric push rod 16 can pull the sliding rod 15 to move, and the sliding rod 15 quickly slides along the slide groove 2 14 opened inside the slide rail 13, pushing the transmission plate 18 and the transmission frame 19 to move forward synchronously. In this process, the electric push rod 16 provides the necessary power, and the sliding rod 15 cooperates with the slide groove 2 14 of the slide rail 13, so that the transmission plate 18 and the transmission frame 19 can move accurately along the specified track. The movement of the transmission frame 19 not only ensures the smoothness of the overall transportation process, but also further drives the movement of the gasket 20. The gasket 20 plays a role in fixing the cable tray through contact with the cable tray.

[0040] Reference Figure 5 - Figure 6The bottom of the sliding rod 15 is fixedly connected to an electric push rod 16, and the output end of the electric push rod 16 is fixedly connected to a connecting block 17. The sliding rod 15 enables it to slide freely in the slide rail 13, and smooth linear motion is achieved through the push of the electric push rod 16. When working, the electric push rod 16 drives the piston rod to move back and forth through its built-in motor. One side of the connecting block 17 is fixedly connected to the bottom of the slide rail 13, and the top of the sliding rod 15 is fixedly connected to a transmission plate 18. Its function is to effectively transmit the power of the electric push rod 16, thereby driving the transmission frame 19 to move synchronously. The transmission frame 19 is fixedly connected to one side of the transmission plate 18. As a supporting component, the transmission frame 19 has the main function of transmitting the power generated by the transmission plate 18 to the gasket 20. One side of the transmission frame 19 is fixedly connected to the gasket 20. The function of the gasket 20 is to provide a certain gap compensation, reduce friction and noise, and ensure that the cable tray will not be damaged due to excessive extrusion during lifting.

[0041] Specifically, the material of the gasket 20 is rubber, which has good elasticity and buffering effect, and can effectively prevent the cable tray from being excessively squeezed or damaged during transportation, thereby ensuring the safety and stability of the cable tray. During use, the gasket 20 firmly fixes the cable tray in the appropriate position by applying uniform pressure, thereby ensuring stability during lifting and installation. In addition, a second slide groove 14 is also provided on the other side of the device, so that the staff can flexibly adjust the device according to the actual width of the cable tray. The existence of the second slide groove 14 allows the sliding rod 15 to slide freely on both sides, which is convenient for fine-tuning the gaskets 20 on the left and right sides to adapt to cable trays of different widths and shapes. Especially for irregular-shaped cable trays, the staff can adjust the gaskets 20 on both sides according to actual needs so that they fit closely with the contour of the cable tray. In this way, the gasket 20 can not only ensure that the cable tray is firmly fixed, but also provide more uniform support to avoid instability caused by irregular shape.

[0042] Working principle: When using the device, the operator places the device at a suitable construction position, places the bridge frame that needs to be transported on the upper surface of the support plate 10, and then drives the support plate 10 through the connecting end of the crane 8 to realize fully automatic transportation. By directly pulling the support rod 3 to make it slide inside the beam 2, the transportation position can be flexibly adjusted according to the construction situation and the needs of the operator. At the same time, through the slide 4 opened inside the support rod 3, the crane 8 can slide inside its slide 4 through the pulley 6, and the position of the crane 8 can be adjusted synchronously, and further cooperated with the support rod 3, making the device more flexible and changeable during operation. At the same time, when it is necessary to fix the cable bridge on the upper surface of the support plate 10 during the transportation process, the slide can be pulled by the output end of the electric push rod 16 When the movable rod 15 moves, the sliding rod 15 will slide quickly along the slide groove 2 14 opened inside the slide rail 13, thereby further driving the transmission plate 18 and the transmission frame 19 to move synchronously. When the transmission frame 19 moves, it will further drive the gasket 20 to move, and the cable bridge will be firmly fixed by the gasket 20. At the same time, since the gasket 20 is made of rubber, it can further protect the cable bridge from excessive extrusion and damage during use. The other side is also provided with a slide groove 2 14, so that the staff can flexibly adjust it according to the actual width of the bridge. According to the specific shape of the bridge, the left and right sides can be fine-tuned respectively, so that it can better conform to the contour of the bridge, achieve close contact and effective fixation with irregular-shaped bridges, and ensure the stability of the bridge during lifting and installation.

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