Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a draggable bearing cable tray device. Background Technology

[0002] When large excavation equipment is used in various engineering projects, a thicker main cable is required to move forward with the large excavation equipment. When the excavation length is short, it is not easily affected by the cable length. However, when the excavation length is long, the main cable supplying power to the large equipment needs to be dragged manually in sections, which is very inefficient and often wastes a lot of time. Utility Model Content

[0003] To solve the above problems, this utility model provides a device that is easy to operate, can ensure insulation, and can also meet the requirements of using machinery to drag cables.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: A towable bearing cable bracket device, comprising a type B semi-closed frame and a rolling bearing mechanism sleeved on its lower part; the type B semi-closed frame includes a vertical rod for connecting to a steel bracket on a structure, a bent section for supporting the cable, and a semi-closed cable inlet, wherein the bent section is connected to the rolling bearing mechanism; the rolling bearing mechanism includes two opposing vertical rolling bearings and a transverse rolling bearing between them, the three of which are respectively fixed at the left, right, and bottom parts of the bent section of the type B semi-closed frame where it contacts the cable.

[0005] The vertical rolling bearing and the horizontal rolling bearing include an outer nylon sleeve, an inner steel sleeve, and a cylindrical bearing rotor located between the two, both ends of which are sealed by waterproof rubber rings and end plugs.

[0006] The cylindrical bearing rotor is a steel cylinder with a circular chamfer. Its inner diameter is equal to the outer nylon sleeve diameter minus the inner steel sleeve diameter minus 0.03 mm.

[0007] The type B semi-closed frame is formed by bending a whole length of round steel. The distance between the end of the semi-closed cable inlet and the vertical pole is 50mm. The round steel is made of Q345B carbon alloy steel with a diameter ≥25mm. The bent section is cold-bent.

[0008] The cylindrical bearing structure and the fishhook-shaped main round steel of this utility model are respectively set in the nylon pulley block structure in three directions. The fishhook-shaped main round steel and the main load-bearing wheel play the role of supporting the weight of the cable passing through. The left guide bearing and the right guide bearing play a guiding role for the cable in the arc section laying device. On the other hand, in the straight section laying device, the cable can be dragged by the guide bearings of the two side bearings and the cable rollers connected to the ends.

[0009] The right guide bearing, left guide bearing, and main bearing of this utility model have the same structure and are all fixed on the main body round steel. The three types of nylon bearings are composed of end plugs, waterproof rubber rings, outer nylon sleeves, inner steel sleeves, and cylindrical bearing rotors. The cylindrical bearing rotor exists between the outer sleeve and the inner sleeve, and the gap is filled with solid lubricating oil. The circular bearing rotor maintains the spacing and fixed position through the end plugs. The end plugs also have small holes to facilitate the injection of lubricating oil into the gaps for maintenance later.

[0010] This utility model has bearings in all directions forming a support system that can effectively transfer the load distributed from the cable to the main round steel. The round steel is then welded to a fixed position where the cable may pass through, so as to provide a function.

[0011] This utility model has a simple structure, ingenious design, and convenient operation. It is not easily affected by the length of the cable. Even when the main cable needs to be dragged manually in sections, it can save construction time and improve construction efficiency. Attached Figure Description

[0016] Example

[0017] like Figure 1 As shown, a towable bearing cable tray device includes a type B semi-closed frame 1 and a rolling bearing mechanism sleeved on its lower part; the type B semi-closed frame 1 includes a vertical rod for connecting to a steel bracket 10 on a structure 9, a bent section for supporting the cable, and a semi-closed cable inlet, the bent section being connected to the rolling bearing mechanism; the rolling bearing mechanism includes two opposing vertical rolling bearings 2 and a transverse rolling bearing 3 between them, the three being fixed at the left, right, and bottom positions of the bent section of the type B semi-closed frame 1 where it contacts the cable.

[0018] like Figure 2As shown, the vertical rolling bearing 2 and the horizontal rolling bearing 3 include an outer nylon sleeve 4, an inner steel sleeve 5 and a cylindrical bearing rotor 6 located between the two. Both ends are sealed by waterproof rubber rings 7 and end plugs 8. The inner steel sleeve 5 is bonded to the type b semi-closed skeleton 1 with metal adhesive.

[0019] The cylindrical bearing rotor 6 is a steel cylinder with a circular chamfer. Its inner diameter is equal to the diameter of the outer nylon sleeve 4 minus the diameter of the inner steel sleeve 5 minus 0.03 mm.

[0020] The type b semi-closed frame 1 is formed by bending a whole length of round steel. The distance D between the end of the semi-closed cable inlet and the vertical pole is 50mm. The round steel is made of Q345B carbon alloy steel with a diameter ≥25mm. The bent section is cold-bent.

[0021] like Figure 3 As shown, the device is first fixed along the planned cable route. After measurement and layout, a suitable linearity and height are selected, with a straight-line layout preferred. The spacing between each device is 1m. After the devices along the route are installed, the cables to be laid are placed inside. Currently, it can support various pure copper main cables with a diameter of up to 200mm. Once all cables are placed inside, the installation of the device and cables is complete.

[0022] During use, the main cable is slowly guided and dragged through the rollers in the series of devices by the cable rollers that come with the large excavation equipment.
