[0002] In the construction of electrical wires and cables, the cable laying frame is one of the core auxiliary equipment, its main function being to support the cable reel and guide the cable to be laid out smoothly. Existing cable laying frames have the following shortcomings: Firstly, the fixed laying height makes it impossible to adjust the laying height according to the construction scenario (such as cable trays of different heights, switching between ground and high-altitude operations), resulting in poor construction adaptability. Secondly, the lack of effective guidance and protection structures during the cable laying process makes the cable prone to deviation and friction wear, affecting the cable's service life and laying efficiency. Third, some height-adjustable wire feeding frames use manual adjustment, which is cumbersome to operate and has low adjustment accuracy. At the same time, they lack a stable positioning structure, and are prone to positional displacement due to vibration after adjustment, posing a safety hazard.

[0003] To solve the above problems, it is urgent to design a wire and cable laying rack that can flexibly adjust its height, provides stable cable laying, and has a reliable structure. Summary of the Invention

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0022] Example 1: The specific structure of this utility model is as follows: Please refer to the appendix. Figure 1-2 The present invention relates to a wire and cable laying rack with a lifting mechanism, comprising: Ground-fixed support assembly; A rotating arm 10 is hinged to the top of the support assembly, and the hinge point between the rotating arm 10 and the support assembly is designated as the first hinge point. A linear telescopic power mechanism, wherein the end of the power part of the linear telescopic power mechanism is hinged to the bracket assembly, and the outer end of its telescopic part is hinged to the rotating arm 10 and is set as the second hinge point; A control structure for controlling the extension and retraction of the linear telescopic power mechanism; A rotating arm positioning structure, one end of which is connected to the rotating arm 10, and the other end of which is detachably connected to the bracket assembly, the rotating arm positioning structure having a hinge structure; The guide wire is provided in two places. The first guide wire is provided at the outer end of the rotating arm 10, and the second guide wire is provided at a height node of the support assembly.

[0023] The support assembly includes a base 4 fixed to the ground by anchor bolts 15, and a vertical pole 14 fixed to the base 4, the upper end of the pole 14 being hinged to the rotating arm 10.

[0024] The power unit is a cylinder 6, and the telescopic part is a telescopic rod. The cylinder 6 drives and connects to the telescopic rod. The upright 14 has a first hinge block at a distance from the first hinge point. The tail of the cylinder 6 is hinged to the hinge block. The first hinge block and the side block mentioned below can be installed as a whole as a fixing block 13 on the upright 14. The rotating arm 10 has a second hinge block located at a distance from the first hinge point, and the outer end of the telescopic rod is hinged to the second hinge block.

[0025] The control structure includes: A first air inlet / outlet 5 is provided at the head of the cylinder 6, and the first air inlet / outlet 5 is connected to a first chamber on one side of the cylinder piston. A second air inlet / outlet 7 is provided on the side of the tail of the cylinder 6, and the second air inlet / outlet 7 is connected to the second chamber on the other side of the cylinder piston; The air circuit switching valve 12 has one end connected to the first air inlet / outlet 5 via a first air pipe, and the other end connected to the second air inlet / outlet 7 via a second air pipe.

[0026] The rotating arm positioning structure includes: A curved rod, the first end of which is fixedly connected to the rotating arm 10; A side block is provided on the upright 14; The first end of the connecting rod 11 is hinged to the second end of the crank rod, and the second end of the connecting rod 11 is connected to the side block by bolts. The connection between the bolts and the side block is a detachable connection structure.

[0027] The first conductor section includes a first guide wheel 3 that is side-fixed to the outer end of the rotating arm 10 and a first wire protector 2 that is side-fixed to the outer end of the rotating arm 10. The first wire protector 2 is located at any position in the fan-shaped area below the first guide wheel 3.

[0028] The first line protector 2 has a through cavity that extends through both ends and has a flared structure, with its wide end facing downwards.

[0029] The second conductor section includes: A vertical block is provided on the upright 14; The second guide wheel 9 is located on the vertical block; A second wire guard 8 is provided on the vertical block, and the wire passage hole of the second wire guard 8 is higher than that of the second guide wheel 9.

[0030] The rotating arm 10 is a curved arm with a turning angle, and the turning angle is an obtuse angle.

[0031] Example 2: The following describes the lifting principle of the wire and cable laying frame of this utility model.

[0032] like Figure 1 As shown, the wire and cable 1 enters from the first wire protector 2, passes through the first guide wheel 3, then through the second wire protector 8 and the second guide wheel 9, and finally enters the wire drawing machine.

[0033] When threading electrical wires and cables for the first time, the rotating arm 10 of the cable laying frame needs to be lowered so that a person can thread the wires while standing on the ground, without needing a frame. The specific operation is as follows: loosen the bolt at the lower end of the connecting rod 11, and move the valve stem of the air circuit switching valve 12 to the right (e.g., Figure 2 (As shown).

[0034] Air is supplied through the first inlet / outlet 5. The pressure in the first chamber is greater than that in the second chamber. The piston retracts, causing the telescopic rod to retract into the cylinder 6. The rotating arm 10 rotates counterclockwise downwards around the first hinge point until it reaches a position where a person can stand on the ground and thread the wire. This invention eliminates the need for scaffolding to thread the wire, reducing labor intensity and safety risks.

[0035] like Figure 2 As shown, the wire and cable 1 is released from the bundled cable reel in an S-shape, as... Figure 1As shown, the first wire protector 2 is shaped like an inverted trumpet. After the wire / cable 1 reaches the first wire protector 2, the first wire protector 2 will force the wire / cable 1 into a straight line, so that the wire / cable 1 will not jump off the first guide roller 3 when passing through the first guide roller 3. When the wire / cable 1 enters the wire drawing machine, it will vibrate. In order to prevent the wire / cable 1 from jumping off the second guide roller 9, a second wire protector 8 is installed in front of the second guide roller 9, so that the wire / cable 1 passes through the second guide roller 9 more smoothly before entering the wire drawing machine.

[0036] Switch the air path switching valve 12 to the left to allow air to enter through the second air inlet / outlet 7. The air pressure in the second chamber is greater than that in the first chamber. The piston moves and drives the telescopic rod to extend outward. In turn, the telescopic rod drives the rotating arm 10 to rise. When the rotating arm 10 stops, the connecting rod 11 is locked to the connecting block 13 with bolts to complete the fixation.

[0037] In summary, this utility model of a cable laying frame offers flexible and adjustable height: The rotating arm is driven by a cylinder to rotate around the hinge point, and combined with the safety control of the air circuit switching valve, the arm can be raised and lowered to adapt to different construction scenarios and improve construction adaptability. This utility model of a cable laying frame provides stable and reliable cable laying: Guide wheels and cable protectors are respectively installed at two conductor sections. The guide wheels reduce cable laying resistance, and the cable protectors effectively prevent cable deviation and friction wear, ensuring a smooth laying process and reducing the risk of cable damage. This utility model of a cable laying frame has a robust and safe structure: The support assembly is fixed to the ground with anchor bolts, and the rotating arm is fixed after adjustment by a positioning structure, avoiding positional deviation caused by vibration, significantly improving overall stability and safety. This utility model of a cable laying frame is convenient and efficient to operate: The air circuit control method is simple to operate, saving manpower and time compared to manual adjustment, and allowing for quick height switching, improving construction efficiency.
