Description

Technical Field

[0001] This utility model relates to the field of cable tray lifting equipment technology, and in particular to a lifting device for cable tray installation. Background Technology

[0002] In the field of cable tray installation, traditional methods face numerous challenges. Previously, cable tray installation relied primarily on manual handling and installation, which was not only labor-intensive but also inefficient. Workers had to expend considerable time and energy moving the cable trays to high installation locations, and fatigue could easily lead to operational errors. Furthermore, manual handling made it difficult to ensure the cable trays were lifted smoothly, resulting in frequent swaying and collisions that could easily damage the cable trays and their internal cables, affecting project quality and cost. The installation and dismantling of the support frames were also cumbersome and complex, often requiring multiple tools and consuming significant time and effort. It was also difficult to flexibly change or adjust the support frames according to the actual needs of the construction site, greatly limiting the flexibility and adaptability of the work. Therefore, we propose a cable tray installation lifting device to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting device for cable tray installation to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cable tray installation lifting device includes: a mounting plate, on the top of which four sets of brackets are fixedly mounted; a rotating shaft is rotatably mounted between two sets of brackets on the same side; a take-up roller is fixedly mounted on the outer side of each set of rotating shafts; gears are fixedly mounted on the outer sides of both ends of each set of rotating shafts, with the gears on the same side meshing; a short shaft is fixedly mounted inside one end of each of the four sets of brackets; a guide roller is fixedly mounted on the outer side of one end of each of the four sets of short shafts; steel cables are provided on the outer sides of each of the four sets of guide rollers; and the steel cables on the same side are wound around corresponding take-up rollers. On the outer side of the roller, two sets of steel cables on the same side are fixedly mounted with fixing plates at their bottom ends. A placement frame is slidably mounted between the two sets of fixing plates. Placement slots are provided inside the two sets of fixing plates. Installation components are provided inside the two sets of placement slots. The installation components include: a frame, a connecting plate slidably mounted inside the frame, an insert plate and a connecting rod fixedly mounted at both ends of the connecting plate, the insert plate being movably inserted into the inside of the fixing plate, a long plate fixedly mounted on the top of the frame, and an insert block fixedly mounted on one side of the long plate, the insert block being movably inserted into the inside of the placement frame.

[0006] Preferably, a square plate is fixedly installed inside the placement rack, and a fixing component is provided at the bottom of the square plate. The fixing component includes a two-way lead screw, two sets of threaded plates are threadedly connected to the outer side of the two-way lead screw, a fixing rod is fixedly installed on the top of each set of threaded plates, and a clamping plate is fixedly installed on the top of each set of fixing rods.

[0007] Preferably, a motor is fixedly installed on one side of the bracket located on the left front side, and the output shaft of the motor is fixedly connected to the rotating shaft located on the left side.

[0008] Preferably, the two sets of frames and long plates are slidably installed inside the corresponding placement slots. Spring 2 and spring 3 are provided inside the two sets of placement slots. The two ends of spring 2 are fixedly connected to the inner wall of one side of the corresponding long plate and placement slot, respectively. The two ends of spring 3 are fixedly connected to the inner wall of one side of the corresponding frame and placement slot, respectively.

[0009] Preferably, the two sets of connecting plates are slidably installed inside the corresponding frames, and each set of frames is provided with a spring. The two ends of the two sets of springs are fixedly connected to the inner wall of one side of the corresponding connecting plate and the frame, respectively. The two sets of connecting rods slide through to one side of the corresponding frame, and a pull plate is fixedly installed at one end of each set of connecting rods.

[0010] Preferably, the bidirectional lead screw is rotatably installed inside both sides of the placement frame, one end of the bidirectional lead screw rotatably passes through to one side of the placement frame, and a rocker arm is fixedly installed at one end of the bidirectional lead screw. Limiting rods are slidably installed inside the two sets of threaded plates, and both ends of the two sets of limiting rods are fixedly connected to the inner walls of both sides of the placement frame. Two sets of sliding grooves are opened inside the square plate, and the two sets of fixed rods are slidably installed inside the corresponding sliding grooves.

[0011] Preferably, the mounting plate has four sets of bolts inside, and four sets of casters are fixedly installed at the bottom of the mounting plate.

[0012] In this utility model, a cable tray installation lifting device is provided with an installation component, a winding roller, gears and guide rollers. The output shaft of the drive motor drives the left rotating shaft to rotate. Since the gears on the two sets of rotating shafts on the same side mesh, the winding rollers on the outer sides of the two sets of rotating shafts rotate accordingly, and begin to wind or unwind the steel cable. When the winding roller winds up the steel cable, the steel cable pulls the bottom pull plate and the connected placement frame to rise, thereby raising the cable tray on the placement frame. When unwinding, the placement frame descends. When the placement frame needs to be installed or removed, pull the pull plate. The pull plate drives the connecting rod, which makes the connecting plate slide within the frame. At the same time, it compresses the spring in the frame, and the insert plate is pulled out from the fixed plate. Pulling the pull plate horizontally left and right causes the insert block to disengage from the inside of the placement frame, at which point the placement frame can be removed. This allows for quick and smooth lifting or lowering of the placement frame and the cable tray on it. The installation components are simple and easy to operate, facilitating the quick installation and removal of the placement frame. The placement frame can be flexibly replaced or adjusted according to actual needs, improving the flexibility and adaptability of the work. Furthermore, the double fixing ensures the firmness and stability of the connection between the placement frame and the fixed plate.

[0013] This utility model describes a cable tray installation lifting device. It includes a fixing component, casters, and bolts. By rotating a bidirectional screw, two sets of threaded plates move in opposite directions along the screw due to the opposite threads at both ends. As the threaded plates move, the top fixing rod and clamping plate move accordingly. Rotating the bidirectional screw allows the clamping plate to tighten or loosen the cable tray. Four sets of casters at the bottom of the mounting plate facilitate the lifting device's movement within the work area. Once at the designated installation position, the lifting device can be fixed to the ground or other installation foundation using four sets of bolts within the mounting plate. This allows for easy tightening or loosening of the clamping plates on the cable tray. The spacing of the clamping plates can be flexibly adjusted according to the size and shape of the cable tray to achieve stable fixing of cable trays of different specifications. This effectively prevents the cable tray from shifting, shaking, or even falling, greatly ensuring the safety and stability of the installation operation. The lifting device can be easily moved and transported between different areas, allowing for faster deployment to various locations where cable trays need to be installed.

Four sets of universal wheels are fixedly installed at the bottom of the mounting plate 1 to facilitate fixing the lifting device to the ground or other mounting foundation and to facilitate the movement of the lifting device in the work area.

[0025] In this embodiment, during use, the output shaft of the drive motor 11 drives the left rotating shaft to rotate. Since the gears 3 on the two sets of rotating shafts on the same side are meshed, when the left rotating shaft rotates, it will drive the right rotating shaft to rotate synchronously in the opposite direction through the gear 3 transmission. The winding rollers 2 on the outer sides of the two sets of rotating shafts rotate accordingly, starting to wind or unwind the steel cable 10. When the take-up roller 2 winds up the steel cable 10, the steel cable 10 pulls the bottom pull plate 801 and the connected placement frame 6 upward, thereby lifting the cable tray on the placement frame 6. When unwinding, the placement frame 6 descends. When the placement frame 6 needs to be installed or removed, pull the pull plate 801. The pull plate 801 drives the connecting rod 802, which causes the connecting plate 805 to slide within the frame 804. At the same time, it compresses the spring 803 inside the frame 804, and the insert plate 806 is pulled out from the fixed plate 7. Pulling the pull plate 801 horizontally causes the insert block 808 to disengage from the inside of the placement frame 6. At this point, the placement frame 6 can be removed. After installation, release the pull plate 801. After step 1, springs 803, 809, and 810 work together to reset the frame 804 and long plate 807. Insert plate 806 re-inserts into fixing plate 7, and insert block 808 re-inserts into placement bracket 6, completing the connection. Rotating the bidirectional screw 901 causes the two sets of threaded plates 902 to move in opposite directions along the screw. As the threaded plates 902 move, the top fixing rod 903 and clamping plate 904 move accordingly. Rotating the bidirectional screw 901 allows clamping plate 904 to tighten or loosen the cable tray. The four sets of casters at the bottom of mounting plate 1 facilitate the movement of the lifter in the work area. After reaching the designated installation position, the lifter can be fixed to the ground or other installation foundation using the four sets of bolts 12 inside mounting plate 1, ensuring stability during operation, preventing displacement during cable tray lifting, and ensuring operational safety.
