Description

Technical Field

[0001] The invention relates to the technical field of building electromechanical engineering, and in particular to an automatic cable laying device composed of nested design modules. Background Art

[0002] At present, cable laying is mainly divided into two forms: horizontal laying and vertical laying. In the case of horizontal laying, the cables are generally placed in the bridge or cable trench. Due to the limited space, the existing equipment cannot directly lay and arrange the cables. Therefore, in most cases, the cable laying-related work is mainly completed with the help of manual labor. In the case of vertical laying, the cables are generally placed in a specific vertical shaft. The conventional operation method is to use the corresponding equipment such as winches to perform vertical traction operations, and fix and install them in stages. The existing cable laying method not only requires a lot of manpower, but also has low laying efficiency and poses a major safety hazard. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the prior art and provide an automatic cable laying device with a nested design module combination to solve the problems that the cable laying process in narrow spaces such as bridges or shafts at the current stage requires a large amount of manual work, and the existing cable laying auxiliary equipment cannot be arranged normally, or the installation process is cumbersome and there are major safety hazards.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0007] The outer frame and the core module adopt a nested connection method to facilitate the installation of the core module. On the one hand, the outer frame can stably install and support the core module and protect the core module. On the other hand, it can make the entire device regular and tangible, with a high degree of integration to adapt to different installation environments and working conditions, so that it can be used in narrow spaces such as vertical shafts.

[0008] The core module main frame serves as an installation frame and can accommodate the installation of the driven clamping assembly, active clamping assembly, drive transmission assembly and guide limit assembly. The driven clamping assembly is fixed on the core module main frame. The active clamping assembly can move relative to the driven clamping assembly under the drive of the drive transmission assembly, and adjust the distance and clamping force between the two to make the active laying wheel and the passive laying wheel approach or move away from each other, so as to clamp the cable to be laid and control the force of clamping the cable. The guide limit assembly plays a guiding and limiting role, so that the movement of the active clamping assembly is based on directionality and accuracy, and will not damage the cable.

[0009] After the cable is clamped, the relative friction force can drive the entire cable to move under the rotation of the active laying wheel to complete the laying; the active laying wheel is arranged in the driven clamping assembly to facilitate connection with the brushless motor on this side for active rotation, avoiding the arrangement of a brushless motor and an active wheel on the side of the driven clamping assembly where the transmission component is already arranged. Such an arrangement is more reasonable and can make full use of the space of the core module main frame.

[0010] Furthermore, the first clamping frame includes a frame side panel that is integrated with the core module main frame, a first mounting plate is screwed and fixed to the frame side panel, the active laying wheel is installed between the first mounting plate and the frame bottom plate of the core module main frame, and the first mounting plate is provided with several protrusions at intervals on one side facing the second clamping frame to form a wavy structure.

[0018] The setting of this guide limit assembly can not only provide precise guiding, but also utilize the front end contactor and the rear end contactor to limit the front and rear end extreme positions, thereby avoiding excessive movement and pinching the cable or damaging other components, and improving safety and reliability.

[0019] Furthermore, the main frame of the core module includes a frame bottom plate, which is provided with a plurality of weight-reducing holes to reduce the overall weight. The side of the frame bottom plate facing away from the drive transmission assembly is also provided with a main control box of the control device. The frame bottom plate is also provided with a plurality of motor mounting holes near one side edge, and the output end of the brushless motor is connected to the active laying wheel through the motor mounting hole; socket pins are respectively provided at the four corners of the frame bottom plate, and the socket pins are used to connect the outer frame.

After insertion, they will be further fixed by bolts to ensure the stability of the connection; the lifting ring mounting hole provided on the socket pin is convenient for connecting the lifting ring to lift the core module as a whole.

A reducer 27 installed on the core module main frame 7 is also provided between the stepper motor 10 and the T-type screw rod 25, and the output end of the reducer 27 is connected to the end of the T-type screw rod 25 through a coupling 26.

[0045] The stepper motor 10 drives the T-type screw rod 25 to rotate, so that the screw slider 23 mounted on the T-type screw rod 25 performs linear reciprocating motion, thereby driving the second clamping frame to move back and forth through the connecting bracket 35.

Among them, the frame bottom plate, drive connecting plate, side plate, etc. of the core module are evenly distributed with certain weight-reducing holes.

[0058] The cable laying process is as follows: the cable is introduced into the cable inlet / outlet 38. Once the infrared sensor 19 detects the cable's entry, the stepper motor 10, in conjunction with the drive transmission assembly, controls the driven clamping assembly 17 to clamp the cable. Fine-tuning is performed using the compression spring and spring compression travel switch to ensure appropriate clamping force. The brushless motor 4 then drives the active laying wheel 18, ensuring its proper operation. The friction between the active laying wheel and the V-shaped rubber wheel transports the cable to the other side. Once cable laying is complete, the clamping assembly is controlled by the hand control box, completing the laying process.
