[0031] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] Example:

[0033] The specific embodiments of the present invention are as follows Figure 1-6 As shown, a cable trough electric cable car comprises a trolley body 1 which is arranged in the cable trough 9 and can move along the extension direction of the cable trough 9, and a cable traction part 11 which can bind the optical / electrical cable 91 is provided at the rear of the trolley body 1. The trolley body 1 is a rectangular box-shaped structure, and its bottom surface is parallel to the bottom surface of the cable trough 9, and the side walls on both sides are parallel to the side walls of the cable trough 9. In order to realize the movement of the trolley body 1 along the cable trough 9, at least two balancing telescopic rods 2 arranged in sequence along the moving direction of the trolley body 1 are vertically inserted on one side wall of the trolley body 1; and a balancing wheel 21 whose wheel surface is in rolling contact with the upper edge of the side wall of the cable trough 9 is sleeved on the free end of the balancing telescopic rod 2.

[0034] At the same time, a clamping telescopic rod 3 is vertically inserted on the other side wall of the trolley body 1, and a clamping wheel 31 is provided on the free end of the clamping telescopic rod 3, the wheel surface of which is in rolling contact with the outer wall of the wire groove 9 and the wheel axle is perpendicular to the bottom surface of the wire groove 9. The trolley body 1 below the clamping telescopic rod 3 is provided with an active running wheel 5, the wheel surface of which is in contact with the inner wall of the wire groove 9 and the wheel axle is perpendicular to the bottom surface of the wire groove 9. In addition, in order to drive the active running wheel 5, a running wheel driving motor 51 is also provided in the trolley body 1, and the running wheel driving motor 51 is electrically connected to the main control module 6 arranged in the trolley body 1.

[0035] In this embodiment, a battery module 8 and a camera module 7 electrically connected to the main control module 6 are also provided in the trolley body 1. The camera of the camera module 7 is set through the front side wall of the trolley body 1. Specifically: the main control module 6 includes a wireless control component, a wireless camera interface, a power supply interface and a motor interface. Among them, the wireless control component can use the 2.4gRF aircraft model receiving and transmitting bidirectional XN297L remote control module of Shenzhen Junye Technology. Through this wireless control component, construction personnel can achieve remote control of the trolley body 1. In addition, the wireless camera interface is connected to the camera module 7, and the situation in front of the wire trough 9 can be photographed and transmitted back to the display of the wireless remote control held by the construction personnel, so that the construction personnel can understand the situation in real time; the battery module 8 is connected to the power supply interface, which can provide power for various devices in the trolley body 1; the motor interface is electrically connected to the walking wheel drive motor 51, which is convenient for the main control module 6 to control the motor.

[0036] Before use, the construction personnel first control and adjust the extension of the clamping telescopic rod 3 and the balancing telescopic rod 2 according to the width of the cable trough 9, so that the clamping wheel 31 and the active walking wheel 5 can clamp the side wall of one side of the cable trough 9, so that a certain pressure is formed between the clamping wheel 31 and the active walking wheel 5, and then the active walking wheel 5 has sufficient friction with the side wall of the cable trough 9. At the same time, the wheel surface of the balancing wheel 21 overlaps the side wall of the other side of the cable trough 9, so as to keep the cable car placed on the cable trough 9 stable. After that, the optical / electrical cable 91 is tied to the cable traction part 11 at the rear of the trolley body 1, and the preparation work before use is completed. When in use, the construction personnel can control the walking wheel drive motor 51 to drive the active walking wheel 5 to rotate by remotely controlling the main control module 6, so that the trolley body 1 moves along the extension direction of the cable trough 9, and then the optical / electrical cable 91 pulled at the rear of the trolley body 1 can be laid in the cable trough 9.

[0037] Therefore, through this cable car, only a small number of construction workers are needed to complete the automatic laying of optical / electrical cables 91, which reduces labor costs and also avoids safety hazards, time waste, low labor efficiency, inconvenient communication and difficult command caused by manual laying, thereby improving the laying efficiency of optical / electrical cables 91.

[0038] In the cable car, a partition 14 is provided in the trolley body 1, which divides the interior into an upper cavity and a lower cavity. Among them, the main control module 6 and the camera module 7 are both arranged in the lower cavity, and the battery module 8 is arranged in the upper cavity. In addition, the running wheel drive motor 51 is arranged in the upper cavity, and the output end of the running wheel drive motor 51 is transmission-connected to the input end of the reduction box 52 arranged in the lower cavity through the partition 14, and the output end of the reduction box 52 is directly connected to the wheel axle of the active running wheel 5. In this embodiment, there are two active running wheels 5 and they are arranged in sequence along the moving direction of the trolley body 1. There are two running wheel drive motors 51 and they are both connected to the two active running wheels 5 one by one through the reduction box 52. The two running wheel drive motors 51 are both electrically connected to the main control module 6, and the two running wheel drive motors 51 are coordinated and controlled to operate synchronously through the synchronization component on the main control module 6.

[0039] As for the installation of the balance telescopic rod 2, a balance rod installation tube 12 is provided in the lower cavity of the trolley body 1 and is sleeved on the outside of the balance telescopic rod 2. A balance rod plug-in section 22 is provided on the side of the balance telescopic rod 2 away from the balance wheel 21. The balance rod plug-in section 22 is provided with a plurality of screw holes 221 arranged in sequence along its axial direction, and the trolley body 1 is provided with fixing screws that penetrate its side wall and are threadedly connected with the screw holes 221. Before starting the laying work, the construction personnel can manually adjust the extension amount of the balance telescopic rod 2 according to the width of the cable trough 9, and then lock the extension amount.

[0040] At the same time, regarding the installation of the clamping telescopic rod 3, a clamping rod mounting tube 13 sleeved on the outside of the clamping telescopic rod 3 is provided in the lower cavity of the trolley body 1. A clamping rod plug-in section 32 is provided on the side of the clamping telescopic rod 3 away from the clamping wheel 31. The clamping rod plug-in section 32 is provided with transmission teeth 321 arranged in sequence along its axial direction, and a clamping rod driving motor 4 is also provided in the lower cavity, and the output end of the clamping rod driving motor 4 is connected to the transmission teeth 321 through a driving gear shaft 41 and a notch 131 provided on the clamping rod mounting tube 13.

Before starting the laying work, the construction personnel can adjust the extension amount of the clamping telescopic rod 3 by controlling the operation of the clamping rod driving motor 4 according to the width of the wire trough 9.

[0041] In addition, in order to avoid frictional contact between the extended telescopic rod 3 and the upper edge of the side wall of the wire groove 9, a guide wheel 33 whose wheel surface is in rolling contact with the upper edge of the side wall of the wire groove 9 is sleeved on the compression telescopic rod 3. At the same time, regarding the specific arrangement of the compression wheel 31, the compression wheel 31 in this embodiment is installed on the free end of the compression telescopic rod 3 through a compression wheel installation rod 311 that vertically passes through the compression telescopic rod 3.
