Referring specifically to fig. 1, the cable construction bracket 10 includes a cable fixing assembly 100, a circumferential supporting assembly 200, and a middle supporting assembly 300, wherein the cable fixing assembly 100 is used for fixing a cable, the circumferential supporting assembly 200 is used for supporting the cable fixing assembly 100 at a plurality of angles in a circumferential direction, and the middle supporting assembly 300 is used for assisting in supporting the circumferential supporting assembly 200 from a middle portion. In this embodiment, the cable fixing assembly 100 includes a body (not shown), a connecting portion 140 disposed on the body, and a receiving through hole 150 penetrating through the body along a first direction (a direction in fig. 1), wherein the receiving through hole 150 is capable of removably fixing a cable. The circumferential support member 200 includes three side support members 210 connected to the connecting portion 140 at equal angles (distributed at 120 °) along the circumferential direction, each of the three side support members 210 is inclined with respect to the second direction (b direction in fig. 1), and one ends of the three side support members 210 away from the cable fixing member 100 are supported on the support surface 10 in a triangular shape. It should be noted that the position of the connecting portion 140 on the body is not limited, and preferably, in an embodiment, the connecting portion 140 includes the bottom surface of the cable fixing assembly 100, that is, the three side supporting members 210 are all connected to the bottom surface of the cable fixing assembly 100. Compared with other connection methods, for example, the three side supporting members 210 can also be connected to the circumferential surface of the cable fixing assembly 100 in an equal angle rotation manner, and the bottom connection arrangement in the present embodiment supports from bottom to top, so that the support is more stable. The middle supporting assembly 300 includes a middle supporting member 310 fixed to the connecting portion 140 and three auxiliary supporting members 320, the middle supporting member 310 is disposed along the second direction, the auxiliary supporting members 320 are disposed between the middle supporting member 310 and the side supporting members 210 and provide supporting force to the side supporting members 210, that is, in the second direction, the connection between the auxiliary supporting members 320 and the middle supporting member 310 is lower than the connection between the auxiliary supporting members 320 and the side supporting members 210. Preferably, in one embodiment, referring to fig. 1, the auxiliary supporting member 320 is vertically supported on the side supporting member 210, so that the supporting force of the auxiliary supporting member 320 vertically acts on the side supporting member 210, and the component force along the length direction of the side supporting member 210 is zero, so that the supporting effect is better. The first direction is perpendicular to the second direction, and it should be noted that the first direction in this embodiment is a horizontal direction, and the second direction is a vertical direction.

In order to meet the construction requirement that cables need to be horizontally arranged along the length direction, the cable construction bracket 10 is provided with a cable fixing assembly 100, which is provided with a receiving through hole 150 penetrating along a first direction, so that the cables can penetrate through the receiving through hole 150 along the first direction and be fixed inside the receiving through hole 150, the cable fixing assembly 100 is supported on the supporting surface 10 of the construction site through a circumferential supporting assembly 200 and a middle supporting member 310, namely three-point support is formed on the supporting surface 10 through three obliquely arranged side supporting members 210, and the three obliquely arranged side supporting members 210 are supported in an auxiliary manner through an auxiliary supporting member 320 arranged between the middle supporting member 310 and the side supporting members 210, so that the support is stable. Compared with the prior art that the construction support adopts the mode of supporting the bottom surface of the base, the three-point supporting mode is more suitable for the uneven supporting surface 10. When slight shaking along the radial direction of the cable in the horizontal plane occurs in the construction process, the cable construction support 10 is supported more reliably.

Referring to fig. 2, in an embodiment, the cable fixing assembly 100 includes a first clamping arm 110 having a connecting portion 140, a second clamping arm 120 disposed opposite to the first clamping arm 110 in a second direction, and a locking member 130 capable of locking the first clamping arm 110 and the second clamping arm 120, wherein the locked first clamping arm 110 and the locked second clamping arm 120 form a body, and a receiving through hole 150 is formed on a surface of the first clamping arm 110 opposite to the surface of the second clamping arm 120. Specifically, as shown in fig. 2, the first grip arm 110 is provided at the lower portion and the second grip arm 120 is provided at the upper portion, and in addition to the above-described arrangement, the first grip arm 110 and the second grip arm 120 may be provided horizontally and laterally to grip the cable. However, compared to the left-right clamping, the vertical clamping is more effective because when the cable is horizontally fixed along the first direction, the gravity is applied to the surface of the lower portion of the cable, and when the first clamping arm 110 and the second clamping arm 120 are oppositely disposed along the second direction, the lower first clamping arm 110 can provide a complete (no butt gap) curved surface to carry the cable.

To facilitate securing a cable between first and second clamping

arms

110, 120 of cable retention assembly 100 during use, with continued reference to fig. 2, second clamping arm 120 is pivotally coupled to first clamping arm 110 in one embodiment. Specifically, one side of the first clamping arm 110 and one side of the second clamping arm 120 may be rotatably connected by a pin (not shown), and a damping structure (not shown) may be provided to limit the maximum rotation angle at which the two are close to each other, for example, the damping structure may be an existing damper. Preferably, the first concave mating surface 111 and the second concave mating surface 121 are respectively disposed on the opposite surfaces of the first clamping arm 110 and the second clamping arm 120, and when the two clamping arms are in a clamping state, a clamping area, i.e. the receiving through hole 150, is formed between the two concave mating surfaces to adapt to the shape of the clamped cable, so as to reduce the possibility of damaging the clamping position of the cable. It should be noted that the curvature of the concave mating surface is set adaptively according to the size of the cable. The cable construction bracket 10 is provided with a first clamping arm 110 and a second clamping arm 120 which can rotate relatively, so that the first clamping arm 110 and the second clamping arm 120 have an opening state and a clamping state, when the second clamping arm 120 is rotated to be far away from the first clamping arm 110, a cable is lapped on the upper part of the first clamping arm 110, and then, when the second clamping arm 120 is rotated to be close to the first clamping arm 110, the first clamping arm 110 and the second clamping arm 120 are locked by a locking piece 130. So set up the construction that is more applicable to power cable, convenient fixed cable.

To facilitate quick locking of the first clamping arm 110 to the second clamping arm 120, with continued reference to fig. 2, in one embodiment, the locking member 130 includes a locking rod 131, one end of the locking rod 131 is rotatably connected to the first clamping arm 110, and the other end of the locking rod 131 is provided with a locking member 132; the locking rod 131 is rotated toward the second clamping arm 120, so that the locking member 132 abuts against the second clamping arm 120 to lock the first clamping arm 110 and the second clamping arm 120. When the cable is placed between the two clamping arms, the locking rod 131 can be rotated to realize quick locking, so that the operation is convenient, and the construction time is saved. It should be noted that the method for disposing the locking member 132 on the locking bar 131 is not limited, and may be a fixed connection or a movable connection, for example, when the fixed connection is adopted, the locking member 132 is disposed in a resilient snap-fit manner and fixed on the end of the locking bar 131, the locking bar 131 is rotated to be close to the second holding arm 120, and the locking member 132 can be snapped on the upper portion of the second holding arm 120 to lock the first holding arm 110 and the second holding arm 120. When the movable connection is adopted, preferably, in an embodiment, the locking member 132 is screwed with the locking rod 131, and the locking member 132 is rotated to move the locking member 132 downward along the axial direction of the locking rod 131, so as to press the second clamping arm 120, thereby increasing the locking force and improving the clamping reliability. It should be noted that, as shown in fig. 2, in one embodiment, the locking member 132 may be provided by a compression nut threadedly coupled to the outer surface of the locking bar 131.

On the one hand, the cable construction holder 10 is convenient to store and move, and on the other hand, the compatibility of the cable construction holder 10 to the uneven support surface 10 is further improved, so that the application range of the cable construction holder 10 is expanded. Referring to fig. 4 to 6 in combination, in an embodiment, the connection parts 140 of the cable fixing assembly 100 are respectively rotatably connected to the three side supports 210, one end of the auxiliary support 320 is rotatably connected to the middle support 310, and the other end of the auxiliary support 320 can move along the length direction of the side supports 210 relative to the side supports 210, so that the side supports 210 can rotate in a direction approaching the middle support 310. On one hand, when the cable construction bracket 10 needs to be moved or stored, as shown in fig. 4, the three side supporting members 210 can be folded towards the direction close to the middle supporting member 310, for example, the three side supporting members 210 are rotated to the limit position close to the middle supporting member 310, so that the folded cable construction bracket 10 has a small volume and is convenient to store and move. On the other hand, referring to fig. 5 and 6 in combination, each of the side supporting members 210 can independently rotate at different angles, and the heights of the supporting points of the side supporting members 210 can be adjusted in a small range due to different rotation angles, so that when the supporting surface 10 of the power cable construction site is uneven, the angle of one or more side supporting members 210 relative to the middle supporting member 310 can be adaptively adjusted to better adapt to the supporting surface 10. In a specific arrangement, in one embodiment, a connecting member 311 is screwed to an end of the middle supporting member 310 away from the cable fixing assembly 100, and the connecting member 311 has three connecting ends arranged at equal angles. Each of the connection ends is rotatably connected to one of the auxiliary supports 320 by a pin. As an example, referring to fig. 1 and 3, the side supporter 210 is sleeved with a connection sleeve 220 that can be adjusted along the length direction of the side supporter 210 and locked to the side supporter 210, and the connection sleeve 220 is rotatably connected to the auxiliary supporter 320. In particular, the connection sleeve 220 may be locked by the locking bolt 221, i.e. the locking bolt 221 is rotated against the side support 210, and may be locked by other methods besides the above-mentioned methods. Before construction, the condition of the on-site support surface 10 is observed, the locking bolts 221 are selectively released to enable the connection sleeve 220 to slide on the side supports 210, and then the connection sleeve 220 is locked after adjusting the angle of the side supports 210.

In order to further improve the compatibility of the cable construction bracket 10 with the inclined support surface 10, referring to fig. 7 and 8, a support plate 211 is movably disposed at an end of the side support 210 away from the cable fixing assembly 100, and the support plate 211 contacts with the support surface 10. This allows to adapt the angle of the support disc 211 with respect to the side support 210 when the support surface 10 is tilted, to always keep the support disc 211 in face contact with the support surface 10. The connection between the support plate 211 and the side support 210 may be a rotational connection via a pin, or other movable connection 311. Preferably, referring to fig. 8, in an embodiment, the support plate 211 is provided with a ball joint 212, and the ball joint 212 is connected to the side support 210, so that the support can be adapted to the support of the support surface 10 inclined to various angles, that is, three positions of surface contact in a triangular distribution can be realized on the support surfaces 10 with different inclination angles, so as to improve the stability of the support, and when slight shaking along the radial direction of the cable in the horizontal plane occurs during the construction process, the reliability of the support of the cable construction support 10 is further improved.
