Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable laying, in particular to a building cable laying device. BACKGROUND

[0002] With the rapid development of high-rise and super high-rise buildings, the cable laying engineering quantity in the bridge increases sharply. At present, the industry generally adopts manual laying or semi-mechanized laying method. The construction personnel first carries the cable in the disc to the bridge entrance, and then two or more workers cooperate. One person lays the cable at a constant speed, and the remaining personnel drag along the line and use simple pulleys or guide rollers to pass the cable into the bridge.

[0003] The above traditional method has the following disadvantages:

[0004] The manual pushing force is difficult to keep constant, and the laying speed is fast and slow, which leads to large cable tension fluctuation, easy to cause outer skin wear, core deformation and even insulation damage; when encountering obstacles such as hanging beams, cross arms or supports for fixing the bridge, the guide clamp must be manually disassembled and assembled or the cable must be temporarily lifted, and the construction stops frequently, which is low in efficiency;

[0005] In the process of avoiding obstacles, the cable is prone to lateral deflection, sagging or winding, which not only increases the subsequent arrangement workload, but also may touch sharp edges to cause secondary damage; when laying for a long distance, the labor intensity of manual dragging is high, a large amount of manpower is needed, and the safety risk increases significantly with the increase of operation height and bridge width;

[0006] The existing semi-mechanized laying vehicle can reduce part of the physical strength, but its laying mechanism and walking mechanism are independent of each other, still need external force to push, and lack the automatic avoidance function of obstacles such as hanging beams, and have poor adaptability in complex bridge paths.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0042] In addition, elements in the present application can be referred to or described as "coupled" with other elements, which can be directly coupled or can be indirectly coupled through one or more intermediate elements. The term "vertical", "horizontal", "left", "right", and the like, are used herein merely to describe the orientation of the elements as shown in the figures and are not meant to be limiting.

[0043] Referring to Figures 1-8 In the embodiment of the present application, the building cable laying device comprises a vehicle body 1 and a base plate 2 fixedly arranged on the vehicle body 1, and a feeding assembly is arranged on the vehicle body 1, which is used to uniformly feed the wound cable.

[0044] A roller 3 is rotatably arranged on the vehicle body 1, and the feeding assembly is connected with the roller 3 through a transmission structure. When the feeding assembly operates, the roller 3 will rotate under the action of the transmission structure, thereby driving the vehicle body 1 to move forward.

[0045] The device further comprises two clamping jaws 4, which are used to guide and limit the cable fed by the feeding assembly, so as to avoid the cable from deviating during the process of laying into the bridge. The two clamping jaws 4 are arranged on the base plate 2 through two sets of switching mechanisms respectively. During the process of moving forward of the vehicle body 1, the two clamping jaws 4 will be sequentially opened to release the limitation on the cable, then avoid the suspended beam fixed on the roof, and then move to the front of the cable to be closed and limited. When the two clamping jaws 4 pass over the suspended beam, the two sets of switching mechanisms will drive the two clamping jaws 4 to reset.

[0046] In the present scheme, once the feeding assembly is started, the rotating movement thereof is synchronously output to the roller 3 through the transmission structure. The roller 3 converts the rotating movement into the forward displacement of the vehicle body 1 under the frictional action. Therefore, the feeding speed and the forward speed of the vehicle body 1 always maintain a fixed transmission ratio, forming the integration of "feeding cable-walking".

[0047] Since the feeding assembly is driven by mechanical transmission instead of manual pushing force, the output rotating speed is constant, and the cable is uniformly drawn out at a constant tension. The vehicle body 1 moves forward synchronously, eliminating the tension fluctuation of the traditional mode of "walking line stop" or "stopping line loosening". After the cable leaves the feeding assembly, it immediately enters the limiting channel formed by the two clamping jaws 4. The clamping jaws 4 are in a closed state in the normal state, clamping the cable at the center line position of the bridge, and preventing the cable from deviating laterally or sagging.

[0048] When the vehicle body 1 moves to the position of the suspended beam, the two sets of switching mechanisms act in the following order:

[0049] The first group of switching mechanisms first opens the gripper 4 near the side of the beam, releases the cable, then moves to the front of the beam, and immediately drives it to close again to restore the limit;

[0050] The second group of switching mechanisms then opens, clears, and closes the other gripper 4 in the same way;

[0051] After the two grippers 4 are reset, the device restores the complete guiding and limiting state and continues to move forward at a constant speed.

[0052] Please refer to Figure 2 and Figure 7 , the feeding assembly includes a rotating shaft 5 and a cable winding wheel 6, the rotating shaft 5 is horizontally arranged on the vehicle body 1, and the cable winding wheel 6 is coaxially fixed on the rotating shaft 5;

[0053] A reduction motor 7 is fixed on the vehicle body 1, and the output end of the reduction motor 7 is coaxially fixedly connected with one end of the rotating shaft 5.

[0054] In this embodiment, when the reduction motor 7 is powered on, the output end generates constant, low-speed, high-torque rotary motion; the output end is coaxially fixedly connected with the rotating shaft 5, and the rotary motion is directly transmitted to the rotating shaft 5 without loss, so that the rotating shaft 5 rotates horizontally at a constant speed; the cable winding wheel 6 is coaxially fixed with the rotating shaft 5, and the rotating shaft 5 rotates one circle, and the cable winding wheel 6 rotates one circle at the same time, and the angular velocities of the two are completely consistent; when the cable winding wheel 6 rotates, the cable originally wound thereon is released at a constant linear speed, forming a uniform speed of release; the released cable then enters the subsequent gripper 4 guiding system to complete the subsequent laying action.

[0055] Please refer to Figure 2 , the transmission structure includes a first pulley 8 coaxially fixed on the rotating shaft 5;

[0056] The second pulley 9 is coaxially fixed on the roller 3, and the first pulley 8 and the second pulley 9 are connected through a toothed belt 10.

[0057] In this embodiment, since the first pulley 8 fixed on the rotating shaft 5 and the second pulley 9 fixed on the roller 3 are connected through the toothed belt 10, when the rotating shaft 5 rotates, the roller 3 will follow the rotation, thereby driving the vehicle body 1 to move forward.

[0058] Please refer to Figure 4 and Figure 5 , the switching mechanism includes a lead screw 11 and a sliding block 12, and a sliding groove 201 is formed in the length direction of the base plate 2;

[0059] The screw rod 11 is horizontally rotatably arranged in the sliding groove 201, and the sliding block 12 is slidingly arranged in the sliding groove 201 and threadedly matched with the screw rod 11;

[0060] The motor 13 is further fixedly arranged on the base plate 2, and an output end of the motor 13 is coaxially fixedly connected with one end of the screw rod 11.

[0061] When the motor 13 is started, the sliding block 12 will slide under the joint action of the screw rod 11 and the sliding groove 201.

[0062] In this embodiment, when the motor 13 is powered, the output shaft thereof generates a precisely controllable angular displacement; the output shaft is coaxially fixed with the screw rod 11, the screw rod 11 is horizontally and synchronously rotated in the sliding groove 201, the angular displacement is completely consistent with the motor 13; the sliding block 12 is circumferentially limited by the sliding groove 201 and can only move linearly along the length direction of the sliding groove 201, and forms a screw pair with the screw rod 11 through the internal thread; when the screw rod 11 rotates, the thread converts the angular displacement into the linear displacement of the sliding block 12, and the sliding block 12 slides forward and backward in the sliding groove 201.

[0063] Please refer to Figure 4 and Figure 8 , the rectangular sleeve 14 is horizontally fixedly arranged on the sliding block 12, and the length direction of the rectangular sleeve 14 is perpendicular to the length direction of the screw rod 11.

[0064] One end of the rectangular sleeve 14 is slidingly matched with the rectangular slide rod 15, and the bottom of the rectangular slide rod 15 is fixedly provided with a sliding seat 17.

[0065] The base plate 2 is fixedly provided with an arc-shaped slide rail 16, and the sliding seat 17 is located in the arc-shaped slide rail 16 and slidingly matched with each other.

[0066] The connecting line between the two ends of the arc-shaped slide rail 16 is parallel to the length direction of the screw rod 11, when the sliding block 12 drives the rectangular sleeve 14 to move along the length direction of the screw rod 11, the rectangular slide rod 15 will move along the length direction of the screw rod 11 and slidingly matched with the rectangular sleeve 14 under the interaction of the sliding seat 17 and the arc-shaped slide rail 16.

[0067] In this embodiment, the motor 13 drives the screw rod 11 to rotate, and the sliding block 12 is limited by the sliding groove 201 and can only move linearly along the axial direction of the screw rod 11; the rectangular sleeve 14 is synchronously translated with the sliding block 12.

[0068] The sliding seat 17 is always locked by the arc-shaped sliding rail 16 and can only slide along the arc track; the sliding seat 17 is connected with the rectangular sleeve 14 through the rectangular slide rod 15; when the rectangular sleeve 14 translates with the sliding block 12, the sliding seat 17 moves in an arc in the arc-shaped sliding rail 16, forcing the rectangular slide rod 15 to slide in the rectangular sleeve 14, so as to simultaneously satisfy the arc displacement of the sliding seat 17 and the linear displacement of the rectangular sleeve 14.

[0069] Please refer to Figure 6 and Figure 8 , the switching mechanism further comprises a rectangular sleeve seat 18 and a rectangular slide column 19 which is in sliding cooperation with one end of the rectangular sleeve seat 18, and the clamping jaw 4 is fixed on the rectangular slide column 19;

[0070] The rectangular sleeve seat 18 is horizontally fixed on the rectangular slide rod 15 through a support 20, and the length direction of the rectangular sleeve seat 18 is parallel to the length direction of the rectangular slide rod 15;

[0071] The rectangular sleeve seat 18 is internally provided with a spring 21, and the two ends of the spring 21 are respectively abutted against the inner wall of the rectangular sleeve seat 18 and one end of the rectangular slide column 19;

[0072] Two limiting rods 22 are fixed on the base plate 2, the positions of the two limiting rods 22 correspond to the two ends of the arc-shaped sliding rail 16 respectively, and the other end of the rectangular slide column 19 is abutted against one of the limiting rods 22, so that the spring 21 is in a compressed state;

[0073] The clamping jaw 4 comprises two arc-shaped clamping plates 401 which are symmetrically and rotationally arranged on the clamping jaw 4, and an adjusting rod 402 is rotationally arranged on the clamping jaw 4 and cooperates with the two arc-shaped clamping plates 401; when the adjusting rod 402 rotates, the two arc-shaped clamping plates 401 can be closed or separated;

[0074] A sleeve ring 23 is fixed on the rectangular sleeve seat 18 and is in sliding cooperation with the outer wall of the adjusting rod 402, a helical groove 4021 is formed in the outer wall of the adjusting rod 402 along the length direction thereof, and a plurality of rolling balls 24 are rollingly embedded in the inner wall of the sleeve ring 23 and in the helical groove 4021.

[0075] In this embodiment, since the rectangular sleeve seat 18 is fixed on the rectangular slide rod 15 through the support 20, under the driving of the chain of the sliding block 12, the rectangular sleeve 14, the sliding seat 17 and the arc-shaped sliding rail 16, the rectangular sleeve seat 18, the rectangular slide column 19 and the clamping jaw 4 obtain a compound displacement of "linear + arc", and the beam is avoided;

[0076] When the whole structure is displaced to the end point of the arc-shaped slide rail 16, the outer end of the rectangular slide post 19 is blocked by the limiting rod 22; the rectangular sleeve 18 continues to move forward, and the spring 21 is further compressed, and the system accumulates elastic potential energy, at this time the arc-shaped clamping plates 401 of the clamping jaw 4 remain in the open state;

[0077] During the continuous forward movement, the ball 24 rolls relatively in the sleeve ring 23, and generates helical displacement along the helical groove 4021 of the adjusting rod 402, forcing the adjusting rod 402 to rotate; the rotation drives the two arc-shaped clamping plates 401 to change from the open state to the closed state through the internal linkage mechanism, realizing the clamping of the cable;

[0078] When the slider 12 moves reversely and the whole structure is separated from the limiting rod 22, the spring 21 releases the potential energy, and the rectangular slide post 19 is pushed out, so that the ball 24 rolls reversely, the adjusting rod 402 reversely rotates, the arc-shaped clamping plates 401 are separated again, and the clamping jaw 4 completes a "open-clamping-open" cycle, preparing for the next avoiding action.

[0079] It is obvious for those skilled in the art that the present application is not limited to the details of the above-mentioned exemplary embodiments, and can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
