Description

Technical Field

[0001] The invention relates to the technical field of subway construction, and in particular to a detachable pay-off frame for subway electromechanical construction. Background Art

[0002] Cable laying is a crucial part of subway electromechanical construction, and the small underground work area is one of the most prominent problems. The space in subway stations and tunnels is limited, and the construction area is often occupied by various equipment, materials and structural components, so the space available for cable laying operations is very tight.

[0003] Traditional cable reels use a passive pay-off method with a horizontal axis. During construction, the pay-off rack needs to move frequently with the project, but the height is fixed and cannot be adjusted. When encountering obstacles such as stairs and low equipment passages, it is difficult to pass through, and it takes a lot of time and energy to adjust or rearrange, affecting the continuity and efficiency of construction; in addition, the pay-off rack with a fixed height occupies a large space in a small site, compressing the operating space of construction personnel and increasing the difficulty of cable collection and arrangement.

[0038] Furthermore, an upper sealing plate 212 is fixedly connected to the top of the first plug-in box via a second bolt 213 .

[0039] In at least one embodiment, taking the first plug-in box as an example, Figure 3 and Figure 4 As shown, the driving mechanism includes an electric cylinder 63, a lower rectangular hole 200 is formed at the bottom of the first plug-in box, a fixed shaft 61 is arranged in the lower rectangular hole, a flip plate 62 is rotatably connected to the fixed shaft, an electric cylinder is fixedly connected to the flip plate, a push plate 64 is connected to the telescopic rod of the electric cylinder, a plug-in guide hole 67 is arranged on the side of the lower rectangular hole away from the fixed shaft, a plug-in guide hole is slidably fitted with a latch 68, a flexible spring 69 is arranged between the plug-in guide hole and the latch, a sliding groove 610 is arranged below the plug-in guide hole, a dial plate 611 is arranged at the lower part of the latch, the dial plate extends to the bottom of the first plug-in box after passing through the sliding groove, and a latch hole matching the latch is arranged on the flip plate to cooperate with it.

[0040] Furthermore, the flip plate is fixedly connected to the limit plate 65 via a first bolt 66 .

[0041] Furthermore, the flexible spring can drive the latch to move toward a side close to the fixed axis.

[0042] When people remove the upper sealing plate, the flip plate rotates until the limit plate contacts the first plug-in box to restrict the flip plate from continuing to rotate. At this time, when the latch is inserted into the latch hole, the electric cylinder is activated to lift the entire device.

[0043] In at least one embodiment, a linkage mechanism is provided between the swing rod and the first plug-in box and the second plug-in box, and the linkage mechanism enables the electric cylinder to push the swing rod 32 to rotate around the first rotating shaft 31 .

[0044] Further, such as Figure 6 As shown, the linkage mechanism includes a moving block 72, a driven push rod 73, a vertical connecting plate 74 and a linkage rod 75. The side walls of the first plug-in box and the third plug-in box are provided with a linkage slide groove 71, and a moving block is slidably matched in the sliding groove. A driven push rod is provided on one side of the moving block, and a vertical connecting plate is provided on the other side. The driven push rod is located in the first plug-in box or the third plug-in box, and a vertical long hole 741 is provided on the vertical connecting plate. A linkage rod is threadedly connected to the rocker arm, and the end of the linkage rod is located in the vertical long hole.

[0045] At this time, the telescopic rod of the electric cylinder extends, the push plate rests on the surface of the driven push rod, and the moving block moves along the sliding groove. At this time, the linkage rod in the vertical long hole is subjected to the horizontal thrust F from the vertical link plate. The horizontal thrust can be decomposed into f1 and f2. f2 is the force in the tangential direction. This force can make the linkage rod rotate around the first rotating shaft. When the pay-off roller is vertically lifted to a certain height, the positioning bolt 54 in the sliding support mechanism 5 can be locked into the threaded hole 55 to achieve the locking of the vertical height of the pay-off roller. At this time, the telescopic rod of the electric cylinder can be retracted, and the electric cylinder can be used for other purposes, such as the overall lifting of the equipment.
