Description

Technical Field

[0001] This invention relates to the field of cable laying equipment technology, and more particularly to a cable laying device. Background Technology

[0002] Currently, cable laying mainly relies on manual labor: a large number of workers are organized to line up along the laying path and drag the cable by hand. For heavy cables, simple rollers are often placed on cable reels and along the path to reduce friction. Another method combines traction machines and manual labor: a fixed cable traction machine (winch) provides the main pulling force, while a large number of workers lift and escort the cable along the line to prevent it from dragging on the ground and getting stuck. This method is heavily reliant on manual labor and inefficient: it requires assembling a large number of people, coordination is difficult, and the laying speed is slow. It also carries high safety risks: manually dragging heavy cables easily leads to muscle strains, bumps, and hand injuries. Cables are easily damaged: manual control is unstable, easily causing the cable to rub against the ground and bend excessively, damaging the outer insulation and shielding layers, affecting cable life. Finally, it has poor adaptability: when encountering complex paths such as turns, slopes, narrow passages, or different elevations, existing simple tools are insufficient to flexibly adjust the lifting height and conveying direction of the cable, making construction extremely difficult.

[0017] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] According to an embodiment of the present invention, a cable laying device includes a mobile platform 4, a lifting mechanism, a cable lifting mechanism, and a control mechanism. The mobile platform 4 is movable relative to the ground. The lifting mechanism includes a hydraulic pump station 1, a hydraulic cylinder 5, a control valve, and a support arm 2. The hydraulic pump station 1 is arranged on the top of the mobile platform 4. The first end of the hydraulic cylinder 5 is pivotally connected to the mobile platform 4, and the second end of the hydraulic cylinder 5 is pivotally connected to the support arm 2. The cable lifting mechanism includes at least one set of cable rollers 3, which support and drive the cable. The cable rollers 3 are connected to the top end of the support arm 2. The control mechanism includes a controller and a control panel. The control panel is equipped with a hydraulic lifting switch and a speed adjustment knob. The controller is electrically connected to the control panel, the hydraulic cylinder 5, and the cable rollers 3. The mobile platform 4 can move omnidirectionally by means of casters. The mobile platform 4 itself has a rectangular frame structure, and anti-fall baffles with a height of 50mm can be installed at the edge of the platform to prevent tools or accessories from slipping. The casters are equipped with a foot-operated braking mechanism. When the brake pedal is depressed, the brake pads fit tightly against the wheel, ensuring that the equipment does not shift during operation (especially during lifting or cable conveying). The hydraulic pump station 1 of the lifting mechanism converts mechanical energy into hydraulic energy, which is then delivered to the control valve via pipelines. The control valve adjusts the hydraulic fluid according to the controller signal, thereby controlling the extension and retraction of the hydraulic cylinder 5. The hydraulic cylinder 5, in conjunction with the support arm 2, adjusts the position of the cable rollers 3, achieving stepless height adjustment of the rollers 3. A set of cable rollers 3 clamps the cable, and the rollers 3 provide friction to drive the cable movement. The control mechanism is conveniently operated through the control panel, and the real-time response of the controller facilitates the coordinated operation of hydraulic lifting and cable conveying.

[0019] The cable laying equipment according to embodiments of the present invention has the advantages of high conveying efficiency and low cable damage.

[0020] In some embodiments, a traction hook or traction rod is provided at one end of the mobile platform 4.

[0021] Specifically, the towing hook can adopt a structure similar to a trailer hitch. The towing hook's surface is electroplated to improve salt spray resistance. The towing rod is made of seamless steel pipe, with a folding hinge in the middle for easy folding. When not in use, it can be folded upwards parallel to the platform, reducing storage space. The towing hook and towing rod improve transfer efficiency and expand the equipment's applicability. The equipment can be moved synchronously with the laying progress by vehicle towing, eliminating the need for repeated equipment handling.

[0022] In some embodiments, a group of cable rollers 3 includes at least two rollers 3, which are spaced apart by a certain distance and whose axial directions intersect to form a space for clamping the cable.

[0023] Specifically, the two idlers 3 are arranged symmetrically in a "V" shape, with their axes intersecting at an angle of 60°-90°. This angle can be finely adjusted via the bracket to accommodate cables of different diameters. The length of the idler 3 is greater than the cable diameter to ensure the cable is completely enclosed within the clamping space. The spacing between the idlers 3 is 1.2-1.5 times the cable diameter, preventing both excessive spacing (causing cable jamming) and excessive spacing (loss of constraint). The bracket has oblong holes, through which the idlers 3 are bolted and fixed to the bracket. Loosening the bolts adjusts the spacing and angle of the idlers 3, quickly adapting to different cable specifications. The "V"-shaped space formed by the two idlers 3 provides radial constraint on the cable, preventing it from slipping off even during turns or steep inclines, thus avoiding repeated manual adjustments. The bearings on the idlers 3 reduce cable drag resistance.

[0024] Optionally, an active drive roller 3 can be added directly above the two idler rollers 3, forming a triangular structure. The active drive roller 3 can be pressed onto the cable by a spring bracket, which ensures that the active drive roller 3 is in contact with the cable. The V-shaped roller 3 and the active conveyor ensure that the cable does not rub against the ground.

[0025] In some embodiments, a drive motor is driven to drive the cable roller 3 to rotate, and the drive motor is driven to drive at least one set of the cable rollers 3.

[0026] Specifically, a drive motor corresponds to a set of cable idlers 3, playing a driving role. The drive motor is a low-speed, high-torque motor such as a hydraulic motor or a frequency converter motor. It provides conveying force through the friction between the cable idlers 3 and the cable surface, forming a pull-and-feed synergy with the traction machine, reducing the traction load and cable internal force. The output shaft of the drive motor is connected to the cable idlers through a reducer or through belt drive.

[0027] In some embodiments, the drive motor is electrically connected to the controller, and the speed of the drive motor is controlled by rotating the speed control knob.

[0028] The speed control knob enables stepless speed regulation of the motor. Through the controller, the speed is matched in real-time with the speed of the front-end traction machine. In conditions such as cable threading and incline work, the speed can be precisely reduced to prevent the cable from accumulating and loosening on the idler rollers 3 or being excessively stretched. Active drive reduces manual pushing and improves conveying efficiency. Stepless speed regulation allows for continuous adjustment of cable conveying within a certain range, avoiding the one-size-fits-all approach of fixed speeds, lowering the operational threshold, and facilitating operation by personnel wearing gloves.

[0029] In some embodiments, a tube-passing guiding mechanism is also included, which includes a guide head and a connecting tube. The guide head is arranged beside the cable roller 3 via a bracket. One end of the connecting tube is connected to the guide head, and the other end of the connecting tube is connected to the tube inlet to be passed through.

[0030] Specifically, the maximum diameter of the guide head is smaller than the inner diameter of the pipe to be inserted, ensuring that the cable enters the pipe smoothly without excessive gaps. The connecting pipe can be a corrugated pipe to facilitate axial tension and radial bending. The bracket is fixed to the front side of the cable roller group 3, and the bottom of the bracket can be bolted to the roller group 3 bracket to ensure that the central axis of the guide head coincides with the center line of the clamping space of the roller group 3. In some embodiments, the guide head is a tapered sleeve.

[0031] Specifically, the tapered sleeve is integrally molded. The small end diameter of the tapered sleeve is at least 3-5mm larger than the outer diameter of the cable to facilitate cable insertion. The large end diameter of the tapered sleeve is 5-8mm smaller than the inner diameter of the pipe to be penetrated, avoiding rigid contact with the pipe wall. Multiple tapered sleeves can be installed and switched according to different cable specifications. The tapered surface of the sleeve provides continuous radial constraint on the cable. If the cable deviates slightly due to delivery deviation, it will automatically correct towards the center under the friction of the tapered surface, ensuring that the cable enters the pipe in a coaxial posture. The large end diameter of the tapered sleeve is close to the inner diameter of the pipe, increasing the contact area between the cable and the sleeve surface.

[0032] In some embodiments, an auxiliary support mechanism is also included, which includes a pull rod and an adjustment seat. The adjustment seat is arranged on the top of the mobile platform 4, one end of the pull rod is connected to the adjustment seat, and the other end of the pull rod is hinged to the middle of the support arm.

[0033] Specifically, the tie rod is made of alloy steel tubing and can consist of two sections connected by a threaded sleeve. This allows for easy adjustment of the overall length of the tie rod, ensuring it fits the gap between the support arm 2 and the adjusting seat. The adjusting seat can have multiple positioning holes, and the end of the tie rod can be inserted into different positioning holes via a pin to adjust the support angle to accommodate different lifting heights of the support arm 2. The top of the tie rod is hinged to the ear plate in the middle of the support arm 2 via a pin. The tie rod, together with the support arm 2 and the moving platform 4, forms a triangular structure, improving the overall structural strength and preventing deformation of the support arm 2. It also distributes the load on the hydraulic cylinder 5, improving equipment reliability.

[0034] In some embodiments, the mobile platform 4 is provided with a plurality of omnidirectional wheels at its bottom, which are used to drive the mobile platform 4 to move.

[0035] Specifically, the casters can be made of anti-static polyurethane, and the steering brackets can be made of stainless steel to provide explosion protection, meeting the needs of explosion-proof environments such as coal mines and chemical plants.

[0036] In some embodiments, the mobile platform 4 is provided with tracks at its bottom, which are used to move the mobile platform 4.

[0037] Specifically, the tracks are arranged on both sides of the bottom of the mobile platform 4. The two tracks are driven independently by two motors. When turning, the controller adjusts the speed difference between the two tracks to achieve steering. The tracks have good anti-sinking ability and slope stability, making them suitable for moving on muddy, soft grass, or gravel roads.
