Description

Technical Field

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

[0002] Cable laying is the process of placing and installing cables along a surveyed route to form a cable line. Depending on the application, cable laying can be categorized into several methods: overhead, underground (in pipes and direct burial), underwater, on walls, and in tunnels. Choosing the right cable laying method is crucial to ensuring transmission quality, reliability, and maintenance.

[0003] According to the requirements of cable laying and the laying method, cable clamps need to be used at certain intervals to fix or install the cables. In the past, the cables needed to be taken out from the cable roll, and the cable length needed to be measured with a ruler, and then marked and cut. This method is prone to errors during measurement due to the long cable length, resulting in incorrect cable length cutting and cable waste. At the same time, manual measurement is required each time, resulting in low work efficiency. Summary of the Invention

[0004] The present invention mainly provides a cable measuring device and a measuring method for electric power engineering construction to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A cable measuring device for power engineering construction, comprising a base, a support frame and two fixed frames mounted on the top of the base, a transmission wheel rotatably connected between the two fixed frames, the transmission wheel being a cavity structure with an opening on one side, a conveying detection mechanism disposed in the transmission wheel region, the conveying detection mechanism comprising a drive motor mounted on one side of the fixed frame and having an output shaft connected to the transmission wheel, a detection rod mounted on the inner wall of one side of the transmission wheel, and two light curtain sensors mounted on the inner side of the fixed frame; the detection rod passes between the two light curtain sensors;

[0007] A wire pressing assembly is installed on the support frame in the top area of ​​the transmission wheel, and a marking mechanism is provided on one side of the support frame. The marking mechanism includes an electric push rod installed on the top of the support frame, a connecting shaft installed at the output end of the electric push rod, and a marking cotton installed in the bottom area of ​​the connecting shaft.

[0008] Optionally, in the present invention, the wire pressing assembly includes a movable rod passing through the support frame, a spring sleeved on the movable rod at the bottom of the support frame, a wheel seat installed at the bottom of the movable rod, and a lower pressing wheel rotatably connected between the wheel seats.

[0009] Optionally, in the present application, a pull knob is mounted on the top of the movable rod.

[0010] Optionally, in the present application, anti-skid stripes are arranged on the surfaces of the pressing wheel and the transmission wheel.

[0011] Optionally, in the present application, limiting rings are arranged on both sides of the transmission wheel, and the diameters of the limiting rings are greater than that of the transmission wheel.

[0012] Optionally, in the present application, mounting pieces are mounted on the bottom of the connecting shaft, mounting holes are arranged on both sides of the mounting pieces, assembling pieces are mounted on the top of the marking cotton, assembling shafts which are matched with the mounting holes are mounted on the top of the assembling pieces, and rubber rings are fixedly sleeved on the assembling shafts.

[0013] Optionally, in the present application, arc-shaped protrusions are arranged on both sides of the mounting pieces, and sliding grooves which are matched with the arc-shaped protrusions are arranged on both sides of the support frame.

[0014] Optionally, in the present application, the connecting shaft and the output shaft of the electric push rod are connected through a shaft coupling.

[0015] Optionally, in the present application, positioning holes are arranged on both sides of the base.

[0016] The measuring method used by any one of the above cable measuring devices for electric power engineering construction comprises the following steps:

[0017] Step one: firstly, the cable is taken out from the cable roller, then the pull knob is pulled upwards to make the pressing wheel rise, then the cable is passed between the transmission wheel and the pressing wheel, and then the pull knob is released, so that the pressing wheel is lowered through the spring force, thereby the cable is limited by the transmission wheel and the pressing wheel;

[0018] Step two: the driving motor is started, so that the transmission wheel rotates, and since the transmission wheel and the pressing wheel limit the cable, the cable is continuously transmitted from the transmission wheel, while the transmission wheel continuously rotates, and the detection rod in the interior continuously passes through the two light curtain sensors, and each passing represents that the cable has passed the circumference of one transmission wheel;

[0019] Step three: when the cable is transmitted and the transmitted distance is detected by the transmission and detection mechanism, when the transmitted distance reaches the set value, the driving motor stops working, the electric push rod works, so that the marking cotton is lowered to make a mark on the cable, and then the driving motor works again, and the process is repeated.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] The present application drives the cable to move by the transmission wheel through the cable from the transmission wheel and the pressing wheel, and through the conveying detection mechanism, cooperates with the movable rod in the transmission wheel and the light curtain sensor, can calculate the length of the cable movement, cooperates with the subsequent marking mechanism, can automatically mark on the cable at the appropriate length, does not need manual measurement of the cable length by using the ruler, avoids the waste of the cable caused by the mistake, saves time and labor, and improves the cable measurement efficiency.

[0034] A line pressing assembly 40 is installed on the support frame 11 in the top region of the transmission wheel 20, a marking mechanism 50 is arranged on one side of the support frame 11, the marking mechanism 50 comprises an electric push rod 51 installed on the top of the support frame 11, a connecting shaft 52 installed on the output end of the electric push rod 51, and a marking cotton 54 installed on the bottom region of the connecting shaft 52.

[0035] It is to be understood that, in the embodiment, the electrical elements of the device are electrically connected with a conventional PLC controller.

[0036] Specifically, please refer to the accompanying drawings Figure 5 The line pressing assembly 40 comprises a movable rod 43 penetrating through the support frame 11, a spring 44 sleeved on the movable rod 43 at the bottom of the support frame 11, a wheel seat 42 installed at the bottom of the movable rod 43, and a pressing wheel 41 rotatably connected between the wheel seats 42.

[0037] It is to be understood that, in the embodiment, the spring 44 is elastic, so that the pressing wheel 41 can be kept pressed, thereby limiting the cables with different diameters.

[0038] Specifically, please refer to the accompanying drawings Figure 5The top of the movable rod 43 is provided with a pull knob 45.

[0039] It should be noted that in the present embodiment, when the cable needs to be passed through the transmission wheel 20 and the pressing wheel 41, the pull knob 45 can be pulled upwards to make the pressing wheel 41 rise, thereby facilitating the passing of the cable.

[0040] Specifically, please refer to the accompanying drawings Figure 1 The surfaces of the pressing wheel 41 and the transmission wheel 20 are provided with anti-skid stripes.

[0041] It should be noted that in the present embodiment, the anti-skid stripes can prevent the pressing wheel 41 and the transmission wheel 20 from slipping with the cable, avoiding the inaccuracy of the length data of the measuring cable caused by slipping.

[0042] Specifically, please refer to the accompanying drawings Figure 3 Both sides of the transmission wheel 20 are provided with limiting rings 21, and the diameters of the limiting rings 21 are greater than that of the transmission wheel 20.

[0043] It should be noted that in the present embodiment, the limiting rings 21 can prevent the cable from falling off the transmission wheel 20.

[0044] Specifically, please refer to the accompanying drawings Figure 6 The bottom of the connecting shaft 52 is provided with a mounting piece 53, both sides of the mounting piece 53 are provided with mounting holes 531, the top of the marking cotton 54 is provided with an assembling piece 55, the top of the assembling piece 55 is provided with an assembling shaft 56 matched with the mounting holes 531, and a rubber ring 561 is fixedly sleeved on the assembling shaft 56.

[0045] It should be noted that in the present embodiment, the marking cotton 54 will run out of ink after a long time of use, leading to unclear marking. However, the convenient separation of the mounting piece 53 and the assembling piece 55 can be achieved by pulling out the assembling shaft 56 from the mounting holes 531, thereby facilitating the replacement of the marking cotton 54.

[0046] Specifically, please refer to the accompanying drawings Figure 2 and Figure 6 Both sides of the mounting piece 53 are provided with arc-shaped protrusions, and both sides of the support frame 11 are provided with sliding grooves 111 matched with the arc-shaped protrusions.

[0047] It should be noted that in the present embodiment, when the mounting piece 53 is lifted, the arc-shaped protrusions on both sides will slide in the sliding grooves 111, thereby making the lifting of the marking cotton 54 more stable.

[0048] Specifically, please refer to the accompanying drawings Figure 6 The connecting shaft 52 and the output shaft of the electric push rod 51 are connected through a shaft coupling.

[0049] Need to explain, in this embodiment, the coupling can increase the stability of the connection between the shaft 52 and the output shaft of the electric push rod 51.

[0050] Specifically, please refer to the attached Figure 1 The base 10 is provided with positioning holes 101 on both sides.

[0051] Need to explain, in this embodiment, by installing the positioning pin in the positioning hole 101, the device can be fixed on the ground, preventing the device from falling during measurement.

[0052] The measuring method used by any of the above cable measuring devices for power engineering construction includes the following steps:

[0053] Step one: first take the cable from the cable roll, then pull the pull button 45 upwards, make the lower pressing wheel 41 rise, then pass the cable between the transmission wheel 20 and the lower pressing wheel 41, then release the pull button 45, make the lower pressing wheel 41 descend by the force of the spring 44, so as to limit the cable by the transmission wheel 20 and the lower pressing wheel 41;

[0054] Step two: start the drive motor 31, so as to make the transmission wheel 20 rotate, because of the limitation of the transmission wheel 20 and the lower pressing wheel 41 to the cable, the cable is continuously transmitted from the transmission wheel 20, at the same time, the transmission wheel 20 rotates continuously, the internal detection rod 33 continuously passes through the two light curtain sensors 32, each time passing through means that the cable has passed the circumference of a transmission wheel 20;

[0055] Step three: when the cable cooperates with the conveying detection mechanism 30 to convey and detect the conveying distance, when the conveying distance reaches the set value, the drive motor 31 stops working, the electric push rod 51 works, makes the marking cotton 54 descend, so as to make a mark on the cable, then the drive motor 31 works again, so on and so forth.

[0056] The above has been described by way of example with reference to the drawings, and it is obvious that the specific implementation of the present application is not limited by the above method. As long as the method concept and technical solution of the present application are adopted for such non-essential improvement, or the concept and technical solution of the present application are directly applied to other occasions without improvement, they are within the protection scope of the present application.
