Description

TECHNICAL FIELD

[0001] The utility model relates to power cable laying technical field especially relates to a power cable land laying power assisting device. BACKGROUND

[0002] Cable laying construction is an important link in the whole power engineering project construction, and requires that the cable insulation sheath cannot be damaged in cable laying operation. However, in actual construction operation, the cable with large cross section is often heavy, and direct dragging on the ground can easily cause abrasion of the insulation sheath. In order to avoid abrasion of the cable caused by friction with the ground, the cable pulley is often used to assist cable laying in the prior art. However, since the cable pulley is only temporarily fixed on the ground to support the cable, the cable pulley is removed after the cable laying is completed. Therefore, the fixed connection strength between the cable pulley and the ground is not particularly high, and the cable laying path is fixed after the cable pulley is fixed on the ground. The cable moves in the supporting groove of the cable pulley, and the weight of the cable itself is large. Therefore, slight deviation during traction of the cable can cause the cable pulley to be overturned, especially in the environment with poor ground conditions. The cable pulley is more likely to be overturned, which leads to great difficulty in cable laying work and extremely low construction efficiency.

[0003] A utility model patent with the authorization announcement number CN218732819U discloses a power line cable laying assisting vehicle, which includes a fixed frame. The fixed frame is a cuboid, and a cable clamp for holding the cable is arranged on the upper part of the fixed frame. A plurality of traction wheels are installed at the bottom of the fixed frame. The traction wheels are divided into four groups, and the four groups of traction wheels are arranged in the front-rear direction. The assisting vehicle mainly plays a supporting and protecting role for the cable during cable laying in the pipeline. The assisting vehicle advances with the cable to achieve the purpose of saving labor. However, when the assisting vehicle is applied to cable land laying, the fixed frame as the core installation frame of the assisting vehicle has a volume much larger than that of the bottom traction wheels. The fixed frame is close to the ground, and the fixed frame itself is a cuboid. This leads to the problem that the assisting vehicle has high requirements for the ground conditions during application, and the fixed frame is easily interfered by obstacles and cannot pass through smoothly.

[0017] The scheme principle of the utility model power cable land laying power-assisted device is: support frame is the support structure of the whole device, the structure of support frame is simplified, so that support frame includes front and rear extending cross bar and front column and rear column fixedly connected at the front and rear ends of cross bar, front wheel is rotatably assembled on front column, rear wheel is rotatably assembled on rear column, support frame is simple frame structure, the space around cross bar, front column and rear column constituting support frame is completely empty, when walking on ground, cross bar, front column and rear column are not easy to interfere with obstacles, so that the overall passability of support frame is better.

[0018] Embodiment of the utility model power cable land laying power-assisted device:

[0019] As shown in Figure 1 The utility model power cable land laying power-assisted device includes support frame 1, support frame 1 is equipped with fixing device 2 for holding cable, support frame 1 is also installed with front wheel 3 and rear wheel 4, wherein front wheel 3 is universal wheel, rear wheel 4 is equipped with two groups and is directional wheel. Support frame 1 includes front and rear extending cross bar 101 and front column 102 and rear column 103 fixedly connected at the front and rear ends of cross bar 101, front wheel 3 is rotatably assembled on front column 102, rear wheel 4 is rotatably assembled on rear column 103. Front column 102 is U-shaped column with opening downward, front wheel 3 is rotatably assembled at the opening end of U-shaped column, part of wheel segment of front wheel 3 enters the U-shaped space of U-shaped column, so that the two parallel edges of U-shaped column form stop limit from left and right sides to front wheel 3. By the two parallel edges of U-shaped column forming stop limit from left and right sides to front wheel, the stability of front wheel can be improved, and then the overall stability of power-assisted device is improved, so that the stability of power-assisted device is better when following cable advancing, and side turning is more difficult to occur. Rear column 103 includes vertically extending longitudinal rod 105 and horizontally extending connecting rod 104 fixedly connected at the bottom of longitudinal rod 105, two groups of rear wheels 4 are rotatably assembled at the two ends of connecting rod 104. Rear column structure is simple, and is not easy to interfere with surrounding obstacles, and two groups of rear wheels are also relatively convenient to assemble on rear column.

[0020] The support frame 1 of the power cable land laying power assisting device is of a simple frame structure, simple in overall structure, convenient to process, and capable of simplifying the structure and reducing the production cost under the premise of meeting the support requirement. The space around the horizontal rod 101, the front vertical column 102 and the rear vertical column 103 of the support frame 1 is completely empty, the horizontal rod 101, the front vertical column 102 and the rear vertical column 103 are not easy to interfere with the obstacles when the power assisting device walks on the ground, so that the support frame is good in overall passability. The support frame has low requirement on the ground condition and can be applied to most land conditions, thereby improving the construction efficiency.

[0021] Of course, the support frame is not limited to the above structure, for example, in another embodiment, the front vertical column of the support frame is an "I" shaped vertical column extending upward and downward, and the front wheels are directly rotationally assembled on the "I" shaped vertical column. For another example, in another embodiment, the rear vertical column of the support frame is a U shaped vertical column with an opening downward, and two groups of rear wheels are respectively rotationally assembled at the lower ends of the two parallel sides of the U shaped vertical column. There are many deformation structures of the support frame, which are not listed here.

[0022] In a preferred embodiment, the fixing device is provided with two groups, as shown in Figure 1 The two groups of fixing devices 2 are arranged in the front-rear direction, wherein the front group of fixing devices 2 is directly above the front vertical column 102, and the rear group of fixing devices 2 is directly above the rear vertical column 103. This arrangement is conducive to more evenly distributing the cable weight on the power assisting device. The cable weight borne by the front group of fixing devices 2 is mainly transmitted to the front vertical column 102, and the cable weight borne by the rear group of fixing devices 2 is mainly transmitted to the rear vertical column 103, so that the front vertical column 102 and the rear vertical column 103 evenly bear the cable weight, providing more stable support for the cable. Moreover, the cable weight borne by the front group of fixing devices 2 is mainly transmitted to the front vertical column 102, and the front wheels 3 are rotationally assembled on the front vertical column 102, and the cable weight borne by the rear group of fixing devices 2 is mainly transmitted to the rear vertical column 103, and the rear wheels 4 are rotationally assembled on the rear vertical column 103, so that the friction between the front and rear wheels and the ground is relatively large, making the front and rear wheels more reliable in gripping the ground, and the power assisting device is less likely to roll over, and has better stability. Of course, in other embodiments, the front group of fixing devices can be arranged obliquely above the front vertical column; the rear group of fixing devices can also be moved forward by a distance to be arranged obliquely above the rear vertical column. The specific position of the fixing device can have many changes, which are not listed here. In addition, the fixing device can also be provided with only one group, or the fixing device can also be provided with more than three groups, and the more than three groups of fixing devices are arranged in the front-rear direction.

[0023] In this embodiment, the fixing device 2 is specifically a cable clamp. As shown in Figure 1As shown in the middle, the cable clamp includes two half clamps, one end of the two half clamps is hingedly assembled together, the other end is provided with a connecting lug, the connecting lug is provided with bolt through holes, and the other end of the two half clamps is fixedly connected through a bolt assembly. One end of the two half clamps is hingedly assembled together and can be opened and closed, which facilitates the tightening and fixing of the cable clamp on the cable, and the operation is more convenient. Of course, in addition to the cable clamp, other structures can also be used, for example, the fixing device includes two clamping plates, one of the clamping plates is fixedly connected with the support frame, and the other clamping plate is fixedly connected with the clamping plate through two groups of bolt assemblies, so that the cable is clamped between the two clamping plates, and the fixing of the fixing device and the cable is realized. The fixing device can also use a wire clamp and the like.

[0024] Considering that the cable land laying may face various land situations, such as the ground conditions of different land situations such as urban land, rural land and mountain land are very different, matching the applicable wheels can further reduce the construction difficulty and improve the construction efficiency, therefore, the front and rear wheels are arranged in a detachable manner, and the front and rear wheels can be detachably mounted on the support frame, and different wheels can be replaced according to the actual land situation during application, so as to adapt to different land situations.

[0025] When the cable laying construction is carried out, multiple assisting devices work cooperatively, as shown in Figure 2 The cable 5 extends along the direction, and one assisting device is arranged at a distance apart. The front wheel 3 of each assisting device will automatically adjust and follow the progress when the cable 5 is pulled by the traction mechanism or manpower, and the rear wheel 4 will follow the front wheel 3 to advance, so that the whole assisting device can follow the cable 5 to advance, and the purpose of not damaging the cable is achieved. The front wheel 3 and the two groups of rear wheels 4 of each assisting device support on the ground, so that multiple point supports are formed between each assisting device and the ground, which can fully guarantee the stability of each assisting device, and a large degree of freedom can be allowed when the cable is pulled without the cable turning over the assisting device, so that the assisting device can relatively stably follow the cable to advance even in the environment with poor ground conditions, thereby greatly reducing the difficulty of cable laying work and improving the construction efficiency. The support frame of the assisting device is a simple frame structure, the overall structure is simple, the space around the horizontal rod, the front column and the rear column constituting the support frame is completely empty, and interference with obstacles is not easy, so that the overall passability of the support frame is good, and the support frame has low requirements on the ground conditions and can be applied to most land conditions, thereby improving the construction efficiency.

[0026] The power cable land laying assisting device has simple overall structure, is convenient to carry and has low manufacturing cost, and can significantly improve the construction efficiency of power cable land laying.
