Technical Field

[0001] The invention relates to the technical field of electric power construction, in particular to a cable laying device for electric power construction. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the application scenarios, it can be divided into several laying methods, such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Long-distance communication cables are generally laid in direct burial to ensure safe and reliable communication. Urban trunk cables (relay and user trunk cables) are generally laid in pipelines to ensure safe and reliable communication, easy installation and replacement, and beautiful appearance. Urban distribution cables can be laid overhead and on the wall.

[0003] In the early stage of cable laying, the cable pipe sections are usually wound and pulled by floor-standing coil equipment. Due to the differences in laying height and depth, and taking into account the influence of cable surface tension and small winding arc, it is often necessary to cooperate with manpower to guide the angle of the cable head and tail ends, and to stop and control the cable in real time according to the ups and downs of the cable and the cable pulling length. The actual difficulty of manual operation is greatly affected by the diameter and weight of the cable pipe, and the buried pipe laying is greatly restricted by the narrow construction scene, and there is a lack of equipment to guide the auxiliary cable laying. Summary of the invention

[0008] A further preferred solution: the inner ring tube is externally connected to an air pump head through a valve port tube.

[0009] A further preferred solution is that the inner ring diameter of the locking ring protrudes to form a corrugated pipeline, and a pipe ring is surrounded on one side of the locking ring close to the inner ring pipe.

[0010] A further preferred solution is that an inner pulley is fixed to one end of the piston ring close to the positioning ring, and the inner pulley is in rolling cooperation with the inner wall of the positioning ring.

[0011] A further preferred solution is that a pair of matching clamping heads are symmetrically arranged on both sides of the guide plate, and matching buckling grooves and positioning rods are arranged at the upper and lower ends of the outer sides of the clamping heads.

DETAILED DESCRIPTION

[0027] See also Figure 1-7 , further illustrate the embodiments of the present invention;

[0028] A cable laying device for power construction, comprising a vehicle seat 1, a guide plate 2 and a wheel tube seat 3, wherein the guide plate 2 and the wheel tube seat 3 are arranged at two ends of the vehicle seat 1 opposite to each other, and characterized in that: a positioning ring 10 is embedded in the guide plate 2, the positioning ring 10 is a semicircular elastic metal ring, and the other semicircle of the positioning ring 10 is connected with an integrally formed locking ring 13, an outer ring 11 is arranged outside the locking ring 13, and an inner ring tube 14 is embedded in the outer ring 11, and a valve port tube 15 and a piston ring 16 are respectively connected at both ends of the inner ring tube 14, and the piston ring 16 is slidably matched with the positioning ring 10, and the ring diameter of the locking ring 13 is associated with the active position of the piston ring 16;

[0029] The motor 6 and the bearing seat 18 are respectively penetrated on both sides of the wheel tube seat 3, a hollow guide groove 19 is formed in the wheel tube seat 3, and a main shaft 20 is penetrated between the motor 6, the guide groove 19 and the bearing seat 18, and the motor 6, the main shaft 20 and the bearing seat 18 are transmission-connected, a cable drum 21 is clamped on the main shaft 20, and an annular groove 25 is formed in one end of the cable drum 21 close to the guide groove 19, and a transmission gear disc 24 is sleeved on the inner end of the cable drum 21 of the main shaft 20;

[0030] In the cable laying device, the guide plate 2 and the wheel tube seat 3 mounted on the vehicle seat 1 serve as the clamping end and the guide pipe section of the cable respectively, wherein the wheel tube seat 3 mainly utilizes the transmission gear plate 24 to roll with the surface of the cable through the transmission of the motor 6 and the main shaft 20, and realizes the guidance of the cable in accordance with the traction direction of the traction end of the cable, and then the cable will pass through the guide plate 2 to lay the cable as the cable traction equipment is fed. During the process, the piston ring 16 and the lock ring 13 can be controlled to slide and retract in relative directions through the inflation state of the valve mouth tube 15 and the inner ring tube 14, and the position of the lock ring 13 relative to the positioning ring 10 and the outer ring 11 can be changed by the sliding contraction of the piston ring 16 toward the side of the positioning ring 10, that is, the relative clamping diameter formed by the positioning ring 10 and the lock ring 13 can be reduced through the position of the inner ring tube 14 and the lock ring 13 in the contracted state to intercept and fix the local cable passing through.

[0031] Compared with the traditional manual cable guiding operation method, the device adopts the wheel tube seat 3 controlled by motor braking and the guiding direction of the guide groove 19 to cooperate with the cable traction equipment to complete the cable winding and releasing operations at the head and tail ends. At the same time, the cable can be partially stopped by pneumatically controlling the guide plate. While ensuring the local stability of the cable winding and releasing tube section, the cable maintains a uniform curvature when it is wound to the horizontal position of the traction force, ensuring the safety of the cable. Combined with the setting of the vehicle body structure, it is convenient to set up in working areas at different heights and depths, avoiding the limitations of traditional manual construction operations and improving the applicability of the device.

[0032] The inner ring tube 14 is connected to the air pump head 12 through the valve mouth tube 15. The pneumatic feed control of the inner ring tube 14 in the device is mainly realized by the air source of the external air pump head 12, and can be combined with the remote control equipment to perform remote opening and closing operations, which is convenient for on-site staff to carry out stop control of cable laying.

[0033] The inner ring diameter of the locking ring 13 protrudes to form a corrugated pipeline, and the locking ring 13 is surrounded by a tube ring on one side close to the inner ring tube 14. The protruding locking ring 13 texture is used to increase the clamping friction coefficient between the locking ring 13 and the outer wall of the cable, so as to improve the clamping strength with the cable when the locking ring 13 is in a contracted state. At the same time, the inner side and the inner ring tube 14 are surrounded by a fixed tube ring to improve the adaptability to the contracted state of the inner ring tube 14.

[0034] An inner pulley 17 is fixed to one end of the piston ring 16 close to the positioning ring 10 , and the inner pulley 17 rolls with the inner wall of the positioning ring 10 . The inner pulley 17 is provided to improve the smoothness and stability of the sliding cooperation between the piston ring 16 and the positioning ring 10 .

[0035] like Figure 4As shown, a pair of matching clamping heads 7 are symmetrically arranged on both sides of the guide plate 2, and matching snap-fit ​​grooves 9 and positioning rods 8 are arranged at the upper and lower ends of the outer sides of the clamping heads 7. The clamping heads 7 are laterally spliced ​​and fixed with multiple guide plates 2 by a left-right combination. According to the construction requirements of multiple pipe sections, the guide plates 2 can be expanded by transversely clamping and fixing the clamping heads 7 to cooperate with multiple rows of cables for guiding operations.

[0036] On the basis of the above, a pair of wheel-rail rods 5 are symmetrically arranged at the bottom of the seat 1, and a track frame 4 is slidably arranged under the wheel-rail rods 5. Considering the needs of the construction scene, the position of the seat 1 is conveniently adjusted by slidingly matching the track frame 4 and the wheel-rail rods 5 to adjust the cable entry angle and position formed by the cable starting end and the wheel tube seat 3.

[0037] The cable drum 21 is concave to form a notched drum diameter, the annular groove 25 is hollow, and the transmission sprocket 24 is protruding from the annular groove 25. The staggered transmission sprocket 24 and annular groove 25 patterns ensure effective contact with the outer wall of the cable, so as to ensure that when the transmission sprocket 24 rotates, the transmission sprocket 24 can adapt to the feeding of the cable through the rolling cooperation of the transmission sprocket 24 to perform rolling cooperation in the same traction direction, thereby improving the smoothness of the cable passing through the wheel tube seat 3.

[0038] The wheel tube seat 3 is rotatably provided with an angle wheel seat 26 at one end of the guide groove 19, and the setting angle of the angle wheel seat 26 is used to conveniently adjust the entry angle of the cable to one end of the guide groove 19 through one end of the cable drum 21.

[0039] The main shaft 20 is externally connected to a clamping seat 22, which is grooved to form a cable tube groove. A plug head 23 is clamped and fixed between the clamping seat 22 and the main shaft 20. The cable tube groove on the clamping seat 22 can be used to adapt large diameter cables through the externally arranged clamping seat 22.

[0040] Working principle: During the construction of the cable laying device, the frame 1 is set up on the cable reeling or unwinding end. When the cable is unwound from the winding end as the traction feeding device unwinds, it will successively pass through the wheel tube seat 3 and the guide plate 2 of the device. When the cable is laid, as the cable is fed, the transmission gear plate 24 is mainly driven by the motor 6 and the main shaft 20 to make rolling contact with the surface of the cable, and the traction force direction of the traction end of the cable is coordinated to achieve the cable guidance. Then the cable will pass through the guide plate 2, and the cable will be laid as the cable traction device feeds. During the process The opening and closing of the air source to the valve port tube 15 and the inner ring tube 14 can be controlled by the external air pump head 12, and the inflation state of the inner ring tube 14 can be controlled by the switch. The relative positions of the piston ring 16 and the locking ring 13 can be changed simultaneously by the contraction and expansion of the inner ring tube 14. The position of the locking ring 13 relative to the positioning ring 10 and the outer ring 11 can be changed by the sliding and extension of the piston ring 16 and the locking ring 13 in the positioning ring 10. The relative clamping diameter formed by the positioning ring 10 and the locking ring 13 can be reduced by the position of the inner ring tube 14 and the locking ring 13 in the contracted state, thereby intercepting and fixing the local cable passing through.
