Description

Technical Field

[0001] The present invention relates to the technical field of ring network cable laying construction, and more specifically, to a ring network frame type wire laying device. Background Art

[0002] The subway ring network cable is a three-phase 35kV AC power, and three high-voltage cables need to be laid in parallel on each path. Existing railway and subway construction teams mainly use two methods to lay cables or wires along the line. One is to lay out the wires and cables using a dedicated track pay-out vehicle, and the other is to use a traditional vertical pay-out frame fixed on the side of the railway and then manually drag the cables or wires.

[0003] However, both of the two methods currently used have the following characteristics: (1) Mechanical laying by railcar is to fix the cable and the pay-off frame on the railcar flatbed, and unwind the cable by the movement of the railcar. Although it will not cause wear on the cable surface, it can only be laid one by one, with low work efficiency and many restrictions on site conditions, and its scope of application is limited; (2) When using a traditional vertical fixed pay-off frame, a lot of manual towing of cables or wires is required, and a large number of temporary pay-off pulleys need to be installed along the cable laying line. The cables and wires need to pass through the pulleys to reduce the towing resistance, which is more troublesome to use and inefficient. At the same time, the cable surface is easily slightly worn during the cable towing process.

[0004] In order to solve the problem of low efficiency and troublesome use of laying out cables on construction sites, a construction vehicle for laying a ring network cable is disclosed in the patent with application number 201220664985.4, which includes a rail flat car and a rail car connected to the rail flat car, a pay-off frame is placed on the rail flat car, a rotatable cable drum is fixed on the pay-off frame, the rail car provides power for the entire device, the rail flat car bears the weight of the pay-off frame and the cables on the pay-off frame, and a special pay-off frame plays the role of fixing the cable drum and the cable. The pay-off frames are preferably 3 in number and arranged in a herringbone shape. Multiple cables can be laid at one time to improve construction efficiency. However, when the above-mentioned construction vehicle is in use, a staff member needs to be configured next to each pay-off frame to control the rotation speed of the cable drum to prevent the cable line from loosening when the cable drum rotates too fast, which may cause the cable coils to cross each other, or the cable coils to turn outside the drum to cause serious cable drum jamming, and also prevent the cable drum from rotating too slowly and the traction strength is too large to pull the cable. This invisibly increases the labor cost, and when the cable drum rotates too fast, manual deceleration can easily cause harm to people. Summary of the invention

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0039] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] like Figures 1 to 6 As shown, the present invention provides a ring network frame type wire-laying device, comprising:

[0041] A flatbed car, used to move the support frame and cable drum 4 described below;

[0042] Specifically, the flatbed vehicle may include a bottom plate 1 and four running wheels disposed on the lower surface of the bottom plate 1, wherein the four running wheels are symmetrically disposed on both sides of the bottom plate 1, so as to carry the cable drum 4 and move along a track or other preset route;

[0043] Among them, the power for driving the flatbed truck can be provided manually, by a tractor, or by a motor that drives the walking wheels to roll, and this application does not impose any restrictions on this.

[0044] Specifically, in order to better control the position of the flatbed, a brake mechanism may be provided on the travel wheel to stop the travel wheel from rolling, thereby maintaining the position of the flatbed relative to the ground and preventing it from continuing to slide and affecting the wiring length and wiring position;

[0045] Specifically, the running wheels of the flatbed truck can be set as universal wheels, which not only facilitates the steering of the flatbed truck, but also facilitates it to avoid obstacles.

[0046] At least three support frames are sequentially arranged on the flatbed vehicle along the front-rear direction of the flatbed vehicle;

[0047] Specifically, the number of the support frames can be set according to the number of cables to be laid. For example, when constructing a subway ring network cable, three cables need to be laid, so three support frames can be set to support the cable trays 4 of the three cables respectively.

[0048] Specifically, the support frame includes a rectangular parallelepiped frame 2, and the left and right sides of the support frame are provided with stiffening ribs 3. The left and right sides of the support frame are each provided with a pair of stiffening ribs 3, and the stiffening ribs 3 are arranged obliquely, and the intersection of the extension lines of each pair of stiffening ribs 3 on the side is located on the axis of the cable drum 4, thereby strengthening the support for the cable drum 4, improving the rigidity and strength of the support frame, and preventing the support frame from being deformed under the gravity of the cable drum 4, thereby affecting the stability;

[0049] Specifically, the support frame can be made of stainless steel, which can prevent dew, rain and other corrosion materials, thereby ensuring the service life of the support frame.

[0050] At least three cable drums 4 are arranged one by one in at least three supporting frames, the rotating shafts 5 of the cable drums 4 are arranged along the left and right directions of the flatbed vehicle, and the rods on the left and right sides of the top of the supporting frame are provided with limiting grooves 6 for placing the rotating shafts 5 of the cable drums 4;

[0051] Specifically, the number of the cable drums 4 can be set according to the number of cables to be laid. For example, when constructing a subway ring network cable, three cables need to be laid, so three cable drums 4 can be set to wind three cables respectively.

[0052] Specifically, a semicircular groove is arranged on the top of the limiting groove 6. On the one hand, the semicircular groove can limit the moving range of the rotating shaft 5 of the cable drum 4. On the other hand, the rotating shaft 5 of the cable drum 4 and the semicircular groove can be in line-surface contact, thereby reducing the contact area between the two and further reducing wear.

[0053] More specifically, a pair of rollers 7 are provided in the limiting groove 6, and the rollers 7 partially protrude out of the semicircular groove. The rotating shaft 5 of the cable drum 4 is placed between the pair of rollers 7. The rollers 7 provide a centripetal supporting force for the rotating shaft 5 of the cable drum 4, which can not only make the cable drum 4 rotate smoothly around the axis of its rotating shaft 5, but also reduce the wear of the rotating shaft 5 of the cable drum 4.

[0054] At least three speed regulating mechanisms are arranged one by one in at least three supporting frames to respectively regulate the speeds of at least three cable drums 4, each of the speed regulating mechanisms comprising:

[0055] A double-headed hydraulic cylinder 8, which is arranged on the flatbed vehicle and located in the supporting frame, wherein two piston rods of the double-headed hydraulic cylinder 8 are respectively arranged along the left and right directions of the flatbed vehicle, and a sliding block 9 is connected to the end of each piston rod, and the sliding block 9 is located outside the cable drum 4;

[0056] Two servo motors 10, which are respectively arranged on two sliding blocks 9, the output shafts of the servo motors 10 are arranged vertically upward, and the output shafts of the servo motors 10 are coaxially connected with friction wheels 11;

[0057] Among them, friction ring plates 12 are arranged on the left and right outer disk surfaces of the cable drum 4. When the two piston rods of the double-headed hydraulic cylinder 8 are retracted, the friction wheel 11 abuts against the friction ring plate 12. When the two piston rods of the double-headed hydraulic cylinder 8 are extended, the friction wheel 11 moves away from the friction ring plate 12.

[0058] In the specific construction process of the above embodiment, one end of the cable is first fixed at the initial position, and as the flatbed vehicle moves, the cable drum 4 can be rotated, so that the cable is gradually laid on the preset path, that is, the head end is fixed and the tail end is movable, which is convenient for controlling the wiring length;

[0059] At the same time, since there are at least three cable drums 4, at least three cables can be laid at the same time, which is conducive to improving the overall wiring efficiency. The support frame is arranged on the outer periphery of the cable drum 4, which can limit the movement of the cable drum 4, thereby reducing the vibration of the cable drum 4 during the laying process and improving the accuracy of the laying position;

[0060] When the cable drum 4 rotates too fast, the servo motor 10 is started to make the linear velocity direction of the friction wheel 11 closest to the cable drum 4 opposite to the linear velocity direction of the cable drum 4 opposite to the friction wheel 11, and then the double-headed hydraulic cylinder 8 is started to retract its two piston rods. After the piston rods are retracted, the friction wheel 11 gradually approaches to contact the friction ring plate 12 on the cable drum 4, and then exerts a friction force on the cable drum 4 in the opposite direction of its rotation through mutual friction. The rotation speed of the cable drum 4 is gradually slowed down under the action of the friction force. When the rotation speed of the cable drum 4 is moderate, the two piston rods of the double-headed hydraulic cylinder 8 can be controlled to extend, so that the friction wheel 11 is away from the friction ring plate 12, and the servo motor 10 is stopped;

[0061] When the cable drum 4 rotates too slowly, the servo motor 10 is started to make the linear velocity direction of the friction wheel 11 closest to the cable drum 4 the same as the linear velocity direction of the cable drum 4 opposite to the friction wheel 11, and then the double-headed hydraulic cylinder 8 is started to retract its two piston rods. After the piston rods retract, the friction wheel 11 gradually approaches to contact the friction ring plate 12 on the cable drum 4, and then exerts a friction force on the cable drum 4 in the same direction of rotation through mutual friction. The cable drum 4 gradually accelerates its rotation speed under the action of the friction force. When the rotation speed of the cable drum 4 is moderate, the two piston rods of the double-headed hydraulic cylinder 8 can be controlled to extend, so that the friction wheel 11 is away from the friction ring plate 12, and the servo motor 10 is stopped.

[0062] Here, the rotation of the cable drum 4 is hindered or accelerated by the friction force between the friction wheel 11 and the friction ring plate 12, and the size of the friction force is also controlled by the contraction force provided by the double-headed hydraulic cylinder 8. Therefore, the friction deceleration process can be carried out in a stepless speed change, so as to avoid applying a large rotation resistance to the cable drum 4 at the beginning, which may easily cause the cable drum 4 to stop suddenly and cause a large pull on the cable, thereby damaging the cable, or avoid applying a large rotation assist to the cable drum 4 at the beginning, which may cause the rotation speed of the cable drum 4 to soar, the cable wound on the cable drum 4 to become loose, and the coils to cross each other.

[0063] The above embodiment uses a speed regulating mechanism to control the speed of the cable drum 4, thereby preventing manual access to the cable drum 4, improving the safety of the equipment and making the operation easier.

[0064] However, in the above embodiment, since the cables released from at least three cable drums 4 may cross, and the crossing of cables is not conducive to accurate cable identification, and the crossed cables may wear each other, the following embodiment makes further improvements.

[0065] In another embodiment, at least two step blocks 13 are provided on the flatbed truck, and the at least two step blocks 13 are sequentially arranged on the flatbed truck along the front and rear directions of the flatbed truck, and the heights of the at least two step blocks 13 are sequentially increased from the rear to the front of the flatbed truck, and at least two support frames are correspondingly arranged on the at least two step blocks 13, so that the at least three support frames are sequentially increased from the rear to the front of the flatbed truck.

[0066] In the above embodiment, the step blocks 13 are provided so that the cable drums 4 are located at different heights. Thus, the cables released from the cable drums 4 are also at different heights, which are not easy to contact and wear each other, and are also convenient for construction personnel to identify the wiring. In addition, since the winding method of the cables on the cable drums 4 is generally the same, even if the release paths of the cables released from different cable drums 4 overlap in the horizontal plane projection, the released cables will not conflict on the release paths due to the different heights.

[0067] Since the ring network cable may be laid on the wall or top of the tunnel, multiple cables of the ring network cable may be laid on the same horizontal plane or at different heights along the tunnel wall. In order to adapt to the different laying requirements of multiple cables, the following embodiments are further improved.

[0068] In another embodiment, a cable guide frame is provided on the flatbed vehicle, and the cable guide frame is provided on the flatbed vehicle and is located behind the at least three support frames, and the cable guide frame includes:

[0069] A pair of vertical plates 14 are arranged opposite to each other in the left-right direction of the flatbed vehicle, a screw rod 15 and a polished rod 16 are rotatably connected between the pair of vertical plates 14, and the polished rod 16 is located above the screw rod 15;

[0070] The guide block 17 has threaded holes matching the screw rod 15 and through holes matching the polished rod 16 on its left and right sides, and the guide block 17 is arranged on the screw rod 15 and the polished rod 16 through the threaded holes and through holes;

[0071] A driving motor 18 is disposed on one of the vertical plates 14. One end of the screw rod 15 passes through the vertical plate 14 on which the driving motor 18 is disposed, and is coaxially connected to the output shaft of the driving motor 18, so that the driving motor 18 drives the screw rod 15 to rotate, thereby moving the guide block 17 along the polished rod 16.

[0072] The guide block 17 is provided with square holes 19 penetrating the front and rear surfaces thereof, and at least three square holes 19 are provided, and the at least three square holes 19 are sequentially raised or lowered from left to right. A guide assembly is provided in each square hole 19, and the guide assembly includes:

[0073] A pair of horizontal guide rollers 20 disposed at the top and bottom of the square hole 19;

[0074] A pair of vertical guide rollers 21 provided on the left and right walls of the square hole 19;

[0075] The pair of horizontal guide rollers 20 is located in front of the pair of vertical guide rollers 21. The pair of horizontal guide rollers 20 and the pair of vertical guide rollers 21 are projected onto the vertical plane in the left and right directions of the flatbed truck to form a tic-tac-toe shape, so that the center of the tic-tac-toe shape is the cable passing channel.

[0076] In the above embodiment, the construction personnel select different square holes 19 according to the cable laying position, so that the cables released from each cable drum 4 pass through the pre-selected square holes 19 respectively. Since the top and bottom of the square hole 19 are provided with horizontal guide rollers 20, when the cable bends upward or downward, the horizontal guide rollers 20 can play a good guiding role, and can also avoid direct friction between the cable and the inner wall of the square hole 19, reducing the resistance of releasing the wire. Similarly, since the left and right walls of the square hole 19 are provided with vertical guide rollers 21, when the cable bends to the left or right, the horizontal guide rollers 20 can play a good guiding role, and can also avoid direct friction between the cable and the inner wall of the square hole 19, reducing the resistance of releasing the wire. In addition, by driving the screw rod 15 to rotate through the driving motor 18, the guide block 17 can be driven to move along the light rod 16, thereby overall controlling the left and right positions of multiple cables passing through the guide block 17, making them closer to the wall surface for laying.

[0077] In another embodiment, the top, bottom, left side wall and right side wall of the square hole 19 are provided with pressure sensors 22, and the horizontal guide roller 20 and the vertical guide roller 21 are respectively installed on the corresponding pressure sensors 22;

[0078] The ring net frame type pay-off device also includes a control unit, which is used to obtain data from each pressure sensor 22 on the top, bottom, left wall and right wall of the square hole 19, and adjust the double-headed hydraulic cylinder 8 and servo motor 10 in the speed regulating mechanism accordingly.

[0079] In the above embodiment, since the horizontal guide roller 20 and the vertical guide roller 21 are respectively installed on the corresponding pressure sensor 22, after the cable passes through the horizontal guide roller 20 or the vertical guide roller 21, the tension on the cable can be detected by the corresponding pressure sensor 22. For example, when the cable needs to be laid on the top of the tunnel, the cable passes through the horizontal guide roller 20 on the top of the square hole 19 and extends obliquely upward. The resultant force generated by the tension on the cable before and after the horizontal guide roller 20 is the pressure on the pressure sensor 22. When the position of the cable drum 4 and the position of the square hole 19 through which the cable of the cable drum 4 passes are determined, the cable extension angle in the tension state of the cable is fixed, so the tension on the cable can be calculated. If the tension is zero, it means that the cable is loose. The cable tension in other directions can also be calculated similarly, and the control unit can preset the tension thresholds of the cable being too tight and too loose under different cable laying situations, so as to compare the measured cable tension with the preset tension threshold, so as to determine whether it is necessary to adjust the double-headed hydraulic cylinder 8 and the servo motor 10 in the speed regulating mechanism.

[0080] The above embodiment combines the pressure sensor 22 with the guide assembly, so that the control unit can accurately obtain the tension condition of the cable, thereby more intelligently controlling the speed adjustment mechanism, improving the automation level of the equipment, reducing the process of manual observation and judgment, and saving labor costs.

[0081] In another embodiment, a protective cover for protecting the cable drum 4 is detachably provided on the top of the support frame. Since the construction site environment is relatively complex, in order to prevent rain or other foreign matter from damaging the wires, a protective cover adapted to the cable drum 4 is provided, and the protective cover is detachably connected to the support frame, so that it can play a protective role when stored at night or in other non-construction situations, and the protective cover can be removed during construction, which has good flexibility.

[0082] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
