Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. Power transmission is one of the important links in the normal operation of cities. When installing power cables, it is usually necessary to support and fix the power cables through installation brackets.

[0003] Existing cable racks are usually provided with single-layer or multi-layer brackets to support power cables. Existing cable racks can only support power cables but cannot effectively limit the power cables. Moreover, since the height of the brackets cannot be adjusted, it is necessary to select a cable rack of appropriate specifications according to the size of the power cables, which makes the flexibility of the cable rack poor.

[0010] When the driving gear moves along the transmission teeth, the linkage component controls the bearing block to move downward.

[0011] The present invention is further configured as follows: the adjustment slot includes a vertical slot and a horizontal slot, the horizontal slots are provided in at least two groups and are respectively connected to the vertical slots, and the limit slot is provided at one end of each horizontal slot away from the vertical slot;

[0012] The adjusting plate is located above the transverse groove.

[0013] The present invention is further configured as follows: the linkage component includes a transmission worm, a transmission worm wheel, a transmission chain and a driving rod, the transmission worm is rotatably connected in the sliding rod, and the driving gear is fixedly connected to the transmission worm;

[0014] The transmission worm wheel is meshed with the transmission worm;

[0015] The lower end of the transmission worm is provided with a transmission part, the lower end of the driving rod is provided with a driving part, and the driving part and the transmission part are arranged through a transmission chain transmission;

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 8 As shown, in order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a power cable installation support frame, comprising a mounting bracket 1 and a bracket 2, the mounting bracket 1 is provided with a plurality of adjustment slots 3 along its height direction, each adjustment slot 3 is laterally connected to a plurality of limit slots 4, and the bracket 2 slides into a limit slot 4 through the adjustment slot 3;

[0036] The support arm 2 includes a sliding rod 21, a detection head 22 and a receiving plate 23. The receiving plate 23 is connected to the middle of the sliding rod 21. At least one detection head 22 is provided and is located at one end of the sliding rod 21. The radius of the detection head 22 is greater than the radius of the sliding rod 21.

[0037] The mounting bracket 1 includes a main frame 11 and a sub-frame 12, the sub-frame 12 is slidably connected to the main frame 11, and an adjustment plate 121 is provided on the sub-frame 12. The adjustment plate 121 is located above the adjustment slot 3 and is used to form a detection gap 13 for cooperating with the detection head 22 with the bottom of the adjustment slot 3;

[0038] A transmission tooth 31 is provided on the lower edge of the adjustment slot 3, a driving gear 24 cooperating with the transmission tooth 31 is rotatably connected to the sliding rod 21, a bearing block 231 is slidably connected to the receiving plate 23, and a linkage component 5 is provided between the bearing block 231 and the driving gear 24;

[0039] When the driving gear 24 moves along the transmission teeth 31 , the linkage component 5 controls the bearing block 231 to move downward.

[0040] The design of the present invention installs the mounting bracket 1 to the cable installation area. Since there will be a soil slope on the ground of the installation area, the mounting bracket 1 is placed unevenly, which causes the mounting bracket 1 at different positions to appear at different heights. At this time, the main frame 11 is first placed stably on the ground or on the soil slope, and then the angle is found for the mounting bracket 1 at the soil slope or a hole is drilled by a tool, and then the sub-frame 12 moves downward along the main frame 11 until the sub-frame 12 abuts against the ground. At this time, if the height of the soil slope is higher, the greater the descending stroke of the sub-frame 12, and the shorter the detection gap 13, the longer the sliding stroke of the sliding rod 21 along the adjusting groove 3, and the driving gear 24 is rotated through the cooperation of the transmission tooth 31 and the driving gear 24, and then the bearing block 231 is driven by the linkage component 5. Finally, the higher the height of the soil slope is, the greater the descending stroke of the bearing block 231 is, and the smaller the height of the soil slope is, the smaller the descending stroke of the bearing block 231 is, thereby ensuring that multiple groups of support arms 2 are located at the same height.

[0041] The present invention is further configured as follows: the adjustment slot 3 includes a vertical slot 32 and a horizontal slot 33, at least two groups of horizontal slots 33 are provided, and are respectively connected to the vertical slots 32, and the limit slot 4 is provided at one end of each horizontal slot 33 away from the vertical slot 32;

[0042] The adjustment plate 121 is located above the transverse groove 33 .

[0043] like Figure 1 As shown, with this structural design, the support arm 2 can be conveniently moved within the same set of adjustment slots 3, and a variety of different heights can be selected within the same set of adjustment slots 3.

[0044] The present invention is further configured as follows: the linkage component 5 includes a transmission worm 51, a transmission worm wheel 52, a transmission chain 53 and a driving rod 54, the transmission worm 51 is rotatably connected to the sliding rod 21, and the driving gear 24 is fixedly connected to the transmission worm 51;

[0045] The transmission worm wheel 52 is meshed with the transmission worm 51;

[0046] The lower end of the transmission worm 51 is provided with a transmission part, the lower end of the driving rod 54 is provided with a driving part, and the driving part and the transmission part are arranged through a transmission chain 53;

[0047] The driving rod 54 is used to drive the bearing block 231 to move up and down.

[0048] The design of this structure is that when the driving gear 24 rotates, the transmission worm 51 rotates accordingly, thereby causing the transmission worm wheel 52 to rotate, and then the transmission part and the driving part are linked through the transmission chain 53, so that the upper driving rod 54 rotates, thereby causing the supporting block 231 to move up and down, thereby achieving the purpose of adjusting the position of the supporting block 231.

[0049] The present invention is further configured as follows: the driving rod 54 includes a driving screw rod and a moving rod, the lower end of the moving rod is provided with a thread groove, the driving screw rod is screwed into the thread groove, and the upper end of the moving rod is connected to the bearing block 231.

[0050] In the design of this structure, the upper end of the moving rod is connected to the bearing block 231, and when the driving screw is rotated, the moving rod can be driven to move upward.

[0051] The present invention is further configured as follows: an inclined slot 122 is provided on the adjustment plate 121 , and the slot size of the slot 122 gradually decreases from one end close to the vertical slot 32 to one end of the limiting slot 4 .

[0052] like Figure 3 As shown, the design of the slot 122 makes the slot 122 close to the vertical slot 32 larger than the slot 122 close to the limiting slot 4, and the slot width of the transverse slot 33 is a certain value. As the adjustment plate 121 continues to descend, the slot width of the transverse slot 33 gradually decreases from the direction of the limiting slot 4 to the direction of the vertical slot 32, while the diameter length of the detection head 22 is continuous. As the adjustment plate 121 continues to descend, the farthest distance that the detection head 22 can pass through will be closer to the vertical slot 32.

[0053] When the detection head 22 cannot pass through, the detection head 22 is moved outward, so that the driving gear 24 on the sliding rod 21 moves in coordination with the transmission gear 31 .

[0054] A limit block may be installed on the other side of the sliding rod 21 to limit the sliding rod 21 on the main frame 11 to prevent the support arm 2 from moving left and right.

[0055] The present invention is further configured such that a measuring rod 123 is provided at the lower end of the sub-frame 12 .

[0056] like Figure 2 As shown, the design of the measuring rod 123 can reduce the downward displacement volume and reduce the opening size of the soil slope.

[0057] The present invention is further configured as follows: abutment plates 111 are extended to both sides of the lower end of the main frame 11 .

[0058] like Figure 1 As shown, the design of the abutment plate 111 can increase the contact area between the main frame 11 and the ground, thereby improving the stability of the prevention.

[0059] The present invention is further configured as follows: a push screw is provided on the main frame 11 for pushing the sub-frame 12 downward. The design of this structure can move the sub-frame 12 downward by rotating the push screw until the measuring rod 123 contacts the ground, thereby avoiding the stability of the detection gap 13. (Not shown in the figure)

[0060] The present invention is further configured as follows: a cable tie 6 is detachably mounted on the bearing block 231, and a plurality of cable ties 6 are arranged along the length direction of the bearing block 231. Figure 4 As shown, the design of the cable buckle 6 can limit and fix the power cable.

[0061] The present invention is further configured as follows: a limit plate 25 is provided on the sliding rod 21 , and the limit plate 25 is installed on a side of the driving gear 24 away from the detection head 22 .

[0062] The design of this structure can ensure that the driving gear 24 and the transmission tooth 31 form a stable fit, with the limiting plate 25 playing a limiting role on one side and the detection head 22 playing a limiting role on the other side.

[0063] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
