Trolley combined pay-off device

Abstract

In the figure 1, a middle shaft (20) is connected through bearings at the two ends, a cable roll, a rubber-insulated optical cable roll, a cable spacer (15), a restraining cable and a rubber-insulated optical cable, a dragging cable and other cable heads are sequentially installed on the middle shaft to drive the bearings to rotate, and cable torsion is removed to enable the cable to be flatly placed in a cable groove in a construction site. The handle connecting rod (1) and the handle (2) are placed in the dragging direction, so that the trolley combined type pay-off device can be prevented from moving towards the dragging direction due to cable dragging.

Description

Technical Field

[0001] The invention belongs to the field of cable laying in building electromechanical construction, and relates to high-voltage electricity construction, fire-fighting electricity construction, weak-voltage electricity construction, and the working environment for laying cables. Background Art

[0002] There are multiple cables and wires being laid out at the same time on the construction site for fire protection, strong current and weak current. For example, the 4-square cable of strong current is relatively hard. If the torsion of the circle is not removed, it is difficult to lay it flat. The sheathed optical cable in weak current has no restraint of the wire release device because of the built-in steel wire. The torsion of the steel wire will cause chaos on site and affect the construction. Summary of the invention Attached Figure 1 The middle shaft (20) is connected by bearings at both ends, and the cable reel, the sheathed cable reel, the cable spacer (15) are installed on the middle shaft in sequence, and the cable and the sheathed cable are restrained, and the cable ends are dragged to drive the bearings to rotate, and the cable torque is removed so that the cable can be placed flatly in the cable groove at the construction site. The handle connecting rod (1) and the handle (2) are placed in the dragging direction to prevent the trolley combined release device from moving in the dragging direction caused by the dragging cable.

[0004] manual: The part numbers in 1, 2, 3, and 4 of the accompanying drawings are unified names.

[0005] (1) Handle connecting rod, (2) Handle is convenient for grasping and pulling the trolley to move the position, connect the handle connecting rod (1), (3) Pull rod connects to the threaded rod of the trolley base, (4) Pull rod connects to the trolley base nut, which is actually welded at the trapezoidal connecting seat of the trolley base, and the handle connecting rod can be directly tightened through the thread. (5) Trapezoidal connecting base, used to connect the pull rod and the base (7) (inner rod of the circular middle axis connector). (6) Trapezoidal connector connecting hole (7) The outer ring of the circular middle axis connector can ensure that the connecting rod can rotate up and down, which is convenient for dragging the trolley combination releaser, (8) The middle axis (bearing) of the trolley wheel makes the wheel rotate, (9) The trolley wheel, (10) The trolley wheel brake assembly, which can be pressed to fix the trolley combination releaser from moving, (11) Fix the trolley wheel to the base (trolley platform), (12) Connect the bearing of the middle axis (20), fixed by the built-in screw, and can rotate through the bearing, (13) Base (Trolley platform), (14) female middle shaft (internal thread nut), used to connect the (18) external thread screw of the male middle shaft (20), (15) cable stopper (cable spacer), (16) round protrusion fixes the cable stopper closest to the base, convenient for assembly and fixation, (17) middle shaft (20) connects the shaft of the base (13), which is equal to the inner diameter of the bearing (12), convenient for assembly, (18) middle shaft (20) male middle shaft (external thread screw), (19) cable schematic diagram, layout schematic diagram, non-accessory. (20) middle shaft includes (14) (16) (17) (18), and is composed of them.

[0006] Instructions for use: As attached Figure 3 , the trolley combined with the wire release device appears in the form of an accessory, which is easy to carry and does not take up space. The trolley can be used alone to carry heavy objects. Convenient and practical. Figure 4 , you can assemble two small cars, which is more convenient. Cable on-site construction basically requires at least two people. One person cannot place the cables, so two people are more convenient. Figure 2 After the trolley is installed, place the first layer of cable baffles and fix the cable baffles through the (16) circular protrusions, and then put the cable rolls in order. After the cable baffles are placed, connect the (18) external thread screw of the middle shaft (20) with the (14) female middle shaft (internal thread nut) of the middle shaft (20) and tighten them to assemble the attached Figure 1 Style, start laying out the lines.
