Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building equipment, especially to a power distribution vehicle cable support, vehicle frame and power distribution vehicle. BACKGROUND

[0002] With the enhancement of environmental protection consciousness and the progress of technology, more and more heavy equipment begins to use electric energy as the main power source. This change not only helps to reduce noise pollution and air pollution at the construction site, but also can improve energy utilization efficiency and reduce operating costs. However, in the actual application process, for some heavy equipment that needs to be moved frequently, such as excavators, pile drivers, etc., their power supply mode faces a series of challenges.

[0003] In the traditional working mode, power supply for these mobile heavy equipment usually means using long-distance cables to be directly connected to fixed power points, but in actual operation, there are significant safety hazards. First of all, due to the complex and changeable environment of the construction site, the ground may be covered with various obstacles, which can easily cause the power line set by the ground to be hung or damaged, causing power failure accidents and even safety accidents. Secondly, when the equipment moves significantly, long-time dragging can cause the cable to be stretched or twisted too much, thereby affecting the service life and safety of the cable. In addition, the cable laying and recycling process is time-consuming and labor-intensive, increasing the difficulty and time cost of the work.

[0004] In order to solve the above problems, a new solution has gradually developed in the industry, that is, through a specially designed power distribution vehicle to follow the heavy equipment to move and effectively manage the cable. This kind of power distribution vehicle can automatically retract and extend the cable, ensuring that the cable always maintains appropriate tension and does not touch the ground, thereby greatly reducing the risk of cable damage. However, due to the special working environment of the power distribution vehicle, the equipment powered by the power distribution vehicle, such as excavators, etc., will have the phenomenon of frequent movement. During the movement, the cable will stretch and retract, and the cable support provided on the power distribution vehicle provides certain support for the cable to prevent the cable from contacting the ground. However, when the electric equipment moves, the cable will change the angle up and down and the angle left and right relative to the power distribution vehicle, and under the condition that the electric equipment driver does not pay attention, the cable is easily stuck on the cable support. SUMMARY

[0005] In order to overcome at least one of the defects of the prior art described above, the utility model provides a power distribution vehicle cable support, vehicle frame and power distribution vehicle, which can solve.

[0006] The technical scheme adopted by the utility model to solve the problem is:

[0007] A power distribution vehicle cable support, comprising:

[0008] A support body comprising a first side plate and a second side plate oppositely arranged, and having a gap between the first side plate and the second side plate;

[0009] A first roller, both ends of which are rotatably mounted to the first side plate and the second side plate respectively, so that the first roller can rotate around its own axis;

[0010] A second roller, both ends of which are rotatably mounted to the first side plate and the second side plate respectively, so that the second roller can rotate around its own axis, and the first roller is parallel to the second roller;

[0011] A third roller, which is rotatably mounted to one side of the first side plate facing the second side plate, and is arranged in a vertical direction, so that the third roller can rotate around its own axis;

[0012] A fourth roller, which is rotatably mounted to one side of the second side plate facing the first side plate, and is arranged in a vertical direction, so that the fourth roller can rotate around its own axis;

[0013] Wherein, the first roller and the second roller have a gap therebetween for the cable to pass through, and the third roller and the fourth roller are located on the same side of the first roller.

[0014] Further, a fifth roller is rotatably connected to one end of the first side plate and the other end of the second side plate, so that the fifth roller can rotate around its own axis, and the fifth roller is arranged on the side of the third roller away from the first roller.

[0015] Further, the first side plate is provided with a first connecting plate on the outer side of the third roller, and the second side plate is provided with a second connecting plate on the outer side of the fourth roller, one end of the fifth roller is rotatably connected to the first connecting plate, and the other end is rotatably connected to the second connecting plate.

[0016] Further, a sixth roller and a seventh roller are rotatably mounted on the first side plate, and the third roller and the sixth roller are symmetrically arranged with the axis of the first roller as the axis of symmetry; the seventh roller is rotatably mounted on the second side plate, and the fourth roller and the seventh roller are symmetrically arranged with the axis of the first roller as the axis of symmetry.

[0017] Further, an eighth roller is rotatably mounted on the first side plate at one end and rotatably mounted on the second side plate at the other end, and the fifth roller and the eighth roller are symmetrically arranged with the axis of the first roller as the axis of symmetry.

[0018] Further, the first side plate is provided with a third connecting plate towards the outside of the sixth roller, the second side plate is provided with a fourth connecting plate towards the outside of the seventh roller, one end of the eighth roller is rotationally connected with the third connecting plate and the other end is rotationally connected with the fourth connecting plate.

[0019] Further, the bracket body further comprises a bottom plate, and the bottom of the first side plate and the bottom of the second side plate are fixedly connected to opposite sides of the bottom plate.

[0020] Further, the first side plate is provided with an inclined rib on the side away from the first roller, so as to limit the inclination of the first side plate towards the side away from the first roller.

[0021] The second side plate is provided with an inclined rib on the two sides away from the first roller, so as to limit the inclination of the second side plate towards the side away from the first roller.

[0022] The utility model also provides a vehicle frame, including above-mentioned distribution vehicle cable support.

[0023] The utility model also provides a distribution vehicle, including above-mentioned distribution vehicle cable support.

[0024] To sum up, the distribution vehicle cable support, vehicle frame and distribution vehicle have the following technical effects:

[0025] 1. The cable is arranged between the first roller and the second roller, and in the process of stretching and recovering, the sliding friction between the cable and the bracket in the prior art is converted into rolling friction, which significantly reduces the friction force on the cable insulation layer in the process of cable extension and recovery, thereby reducing the risk of cable jamming or winding.

[0026] 2. The third roller is installed on the side of the first side plate facing the second side plate and is arranged in the vertical direction. That is, the third roller is located on one side of the cable support, and when the cable is deflected to the limit position in the direction of the third roller due to the movement of the electrical equipment, the cable will first contact the third roller. Because the third roller can freely rotate around its own axis, even in extreme cases, the cable can smoothly roll on the roller instead of being hard blocked, thereby greatly reducing the possibility of cable jamming.

[0027] 3. The fourth roller is installed on the side of the second side plate facing the first side plate and is arranged in the vertical direction. That is, the third roller is opposite to the fourth roller, which together provides support on both sides of the cable. When the cable is deflected to the limit position in the direction of the fourth roller, the cable will contact the fourth roller. Since the fourth roller can also freely rotate around its own axis, the cable can smoothly roll on the roller, avoiding the jamming phenomenon caused by hard contact and ensuring the smooth movement of the cable.

[0028] 4. The first roller, the second roller, the third roller and the fourth roller in contact with the cable are all converted into rolling friction, thereby reducing the friction of the cable when in contact with the above four, thereby reducing the wear and tear of the cable insulation layer during the stretching and recovery process.

The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0037] Referring to Figs. 1-3 The utility model discloses a kind of distribution car cable support, comprising: support body 1, first roller 2, second roller 3, third roller 4 and fourth roller 5, support body 1 includes oppositely arranged first side plate 11 and second side plate 12, first side plate 11 and second side plate 12 have gap between, two ends of first roller 2 are respectively rotationally assembled to first side plate 11 and second side plate 12, to enable first roller 2 can rotate around its own axis, two ends of second roller 3 are respectively rotationally assembled to first side plate 11 and second side plate 12, to enable second roller 3 can rotate around its own axis, and first roller 2 and second roller 3 are parallel, third roller 4 is rotationally installed in the side of first side plate 11 towards second side plate 12, and it is arranged along vertical direction, to enable third roller 4 can rotate around its own axis, fourth roller 5 is rotationally installed in the side of second side plate 12 towards first side plate 11, and it is arranged along vertical direction, to enable fourth roller 5 can rotate around its own axis, wherein, first roller 2 and second roller 3 have gap between, to be used for cable to pass through, third roller 4 and fourth roller 5 are located in the same side of first roller 2.

[0038] Specifically, the bracket body 1 is composed of a first side plate 11 and a second side plate 12, the first side plate 11 and the second side plate 12 are oppositely arranged and have a gap therebetween, so as to install the respective rollers between the first side plate 11 and the second side plate 12 and also provide a certain range for the deflection of the cable. The two ends of the first roller 2 and the second roller 3 are respectively rotatably assembled to the first side plate 11 and the second side plate 12, so that the two rollers can freely rotate around their own axes. The first roller 2 and the second roller 3 are arranged in parallel and maintain a certain gap therebetween, which is used for the cable to pass through, not only can ensure that the cable can smoothly move between the first roller 2 and the second roller 3, but also allows the cable to perform rolling friction instead of sliding friction during its extension or retraction, thereby reducing the risk of the cable being stuck during movement and reducing the wear on the cable insulation layer.

[0039] In some embodiments, the power distribution vehicle cable bracket further comprises a fifth roller 6, one end of the fifth roller 6 is rotatably connected with the first side plate 11, and the other end is rotatably connected with the second side plate 12, so that the fifth roller 6 can rotate around its own axis, and the fifth roller 6 is arranged on the side of the third roller 4 away from the first roller 2.

[0040] Specifically, the fifth roller 6 is arranged on the side of the third roller 4 away from the first roller 2. Since the cable bracket is usually installed on the top of the power distribution vehicle, the cable generally does not encounter obstacles when rotating upward, but may be limited by other components of the power distribution vehicle (such as the vehicle body structure, the power distribution cabinet, etc.) when rotating downward. By arranging the fifth roller 6 on the side away from the third roller 4, when the cable rotates downward relative to the cable bracket, the cable can change direction after contacting the fifth roller 6, which allows the cable to smoothly pass over the fifth roller 6 and then adjust the direction, thereby avoiding interference with the components of the power distribution vehicle.

[0041] And the fifth roller 6 can freely rotate around its own axis, which can ensure smooth rolling of the cable even if pressure is applied or the angle changes during the change of direction, greatly reducing the probability of the cable being stuck, and by providing a rotating contact surface for the cable, reducing the wear on the cable insulation layer and protecting the integrity and service life of the cable.

The seventh roller 8 is rotatably assembled on the second side plate 12 and symmetrically arranged with the fourth roller 5 with the axis of the first roller 2 as the axis of symmetry. The existence of the sixth roller 7 and the seventh roller 8 increases the contact points between the cable and the support, so that the cable has more support points to choose from when the angle changes greatly, reducing the risk of the cable being stuck or wound.

[0045] In some embodiments, in order to improve the fitting effect of the cable support, the power distribution vehicle cable support further comprises an eighth roller 9, one end of the eighth roller 9 is rotatably assembled on the first side plate 11 and the other end is rotatably assembled on the second side plate 12, and the fifth roller 6 and the eighth roller 9 are symmetrically arranged with the axis of the first roller 2 as the axis of symmetry.

[0047] Specifically, by only adding these two small-volume third and fourth connecting plates 112 and 122, the installation of the eighth roller 9 can be easily realized.

[0051] The side of the second side plate 12 away from the first roller 2 is provided with an inclined rib 14 to limit the tilting of the second side plate 12 towards the side away from the first roller 2.
