Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction equipment, in particular to a temporary bracket for cables. Background Art

[0002] Cable laying is an important step in power installation projects. Due to the long length of the cable, the high-voltage cable will inevitably pass through the road and cross over the road during the laying process. In the process of laying, in order to ensure the smooth flow of the road, a temporary rack is built to support the cable. Due to the simple structure of the rack, the effect is generally poor, which causes the cable across the road surface to bend easily, affecting the appearance of the road surface.

[0003] In the prior art with patent number CN111049059B, when the cable passes through its support tube and then bridges over the road surface, although the support tube is elastic, the entire support tube is also bridged over the road surface, and the support tube itself and the cable inside the support tube are also prone to bending towards each other, so the problem of the middle part of the cable bending under the action of its own weight cannot be truly solved. Utility Model Content

[0004] The purpose of the utility model is to provide a temporary bracket for cables to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temporary bracket for a cable, comprising a base and a support member slidably mounted on the base; the base comprises a column, and the support member slidably cooperates with the column through a guide column; a spring is also provided inside the column; wherein, one end of the spring abuts against the bottom of the column, and the other end of the spring abuts against the bottom surface of the guide column; a support frame is also provided at the upper end of the guide column, and a sleeve is provided in the middle of the support frame to be sleeved on the outside of the cable, and the sleeve is connected to a counterweight block; when the cable passes through the sleeve, the counterweight block prompts the sleeve to move downward, so as to stretch the cable located on the outside of the support frame toward the inside of the support frame, so that the cable passing through the support member can cross the road surface straightly.

[0006] As the preferred technical solution of the utility model: both ends of the support frame are connected with swinging parts by axial pins; wherein, one end of the cable first passes through the swinging part at one end of the support frame and then enters into the sleeve, and then continues to pass through the swinging part at the other end of the support frame to hang the cable on the support member.

[0007] As a preferred technical solution of the utility model: a through hole is further provided in the middle of the support frame, and the counterweight block enters into the interior of the guide column after passing through the through hole.

[0008] As a preferred technical solution of the utility model: the counterweight block is movably connected to the sleeve via a provided traction rope.

[0009] As a preferred technical solution of the utility model: the guide column slides inside the column through a provided support block, and is covered on the top of the column through a provided end cover to prevent the guide column from being separated from the column.

[0010] As a preferred technical solution of the utility model: the support block is connected to the guide column through a provided bolt, and the bolt passes through the end cover to fix the end cover on the column.

[0011] As a preferred technical solution of the utility model: the cross-sections of the guide column and the column are both rectangular, and the interior of the column is connected to the outside through the provided guide hole.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are as follows: 1. After the cable passes through the sleeve, the counterweight block is used to push the sleeve downward, so as to stretch the cable located outside the support frame toward the inside of the support frame, and then the cables located on both sides of the support frame can be stretched toward the middle of the support frame, so that the cable can cross the road surface relatively straight;

[0013] 2. As the counterweight slides inside the column, when the cable contracts, the counterweight is pushed inside the column, so that the cable has sufficient tensile capacity. At the same time, the guide column slides inside the column and is reset by the spring, so that the cable suspended on the support frame can be more stably located on the support frame. Based on this, the device can solve the problem of bending of the cross-road cable, so that the cable can cross the road more straightly. In particular, placing the device in the middle of the road will have a better effect on straightening the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-4 The utility model provides an embodiment: a temporary bracket for a cable, comprising a base 1, a support member 2 slidably mounted on the base 1; the base 1 comprises a column 10, and the support member 2 is slidably matched with the column 10 through a guide column 20; a spring 11 is further provided inside the column 10; wherein one end of the spring 11 abuts against the bottom of the column 10, and the other end of the spring 11 abuts against the bottom surface of the guide column 20;

[0021] In summary, by installing the spring 11 between the column 10 and the guide column 20, the spring 11 can be used to always push the guide column 20 to slide upward, thereby reliably maintaining the height of the cable; secondly, when the cable swings slightly, the vibration of the cable can be absorbed.

[0022] A support frame 24 is also provided at the upper end of the guide column 20, and a sleeve 28 is provided in the middle of the support frame 24 and is sleeved on the outside of the cable, and the sleeve 28 is connected to a counterweight 25; when the cable passes through the sleeve 28, the counterweight 25 causes the sleeve 28 to move downward, so as to stretch the cable located outside the support frame 24 toward the inside of the support frame 24, so that the cable passing through the support member 2 can cross the road surface straightly.

[0023] In summary, the counterweight 25 is hung on the cable, so that the weight of the counterweight 25 is used to tighten the cable, thereby overcoming the bending of the cable. At the same time, when the cable is affected by airflow, the counterweight 25 slides inside the column 10 to cause the cable to calm down quickly.

[0024] In addition, due to the arrangement of the counterweight 25 and the spring 11, the cable can be installed on the ground in a non-fixed manner. Therefore, when the cable is impacted by airflow, it can expand and contract accordingly to reduce the damage to the cable caused by the airflow. In particular, the counterweight 25 can always push the cable downward, and the spring 11 can always push the support frame 24 upward, so the problem of cable outlet bending can be effectively solved.

[0025] Furthermore, both ends of the support frame 24 are connected to swing members 26 by shaft pins; wherein, one end of the cable first passes through the swing member 26 at one end of the support frame 24 and then passes through the sleeve 28, and then continues to pass through the swing member 26 at the other end of the support frame 24 to hang the cable on the support member 2. In the above manner, the swing member 26 is used to cut off the direct contact between the cable and the two ends of the support frame 24, and the swing member 26 can swing freely at the two ends of the support frame 24, so that the cable inside the support frame 24 and the cable outside the support frame 24 can bend freely, so as to reduce the wear between the cable and the support frame 24.

[0026] Furthermore, since a through hole 23 is provided in the middle of the support frame 24, and the counterweight 25 enters into the interior of the guide column 20 after passing through the through hole 23, it is convenient to install the counterweight 25 into the interior of the guide column 20, thereby reducing the influence of the airflow on the counterweight 25, thereby avoiding the phenomenon that the cable outlet is driven by the counterweight 25 to swing.

[0027] Furthermore, since the counterweight 25 is movably connected to the sleeve 28 via the traction rope 27, the counterweight 25 and the sleeve 28 can be easily assembled and disassembled. The provision of the traction rope 27 also facilitates the counterweight 25 to penetrate into the interior of the guide column 20.

[0028] On the basis of the above scheme, since the guide column 20 slides inside the column 10 through the support block 21 and covers the top of the column 10 through the end cover 12 to prevent the guide column 20 from separating from the column 10, the phenomenon of the guide column 20 and the column 10 falling off from each other can be effectively avoided.

[0029] At the same time, the support block 21 is connected to the guide column 20 through the provided bolts 22, and the bolts 22 pass through the end cover 12 to fix the end cover 12 on the column 10. Therefore, the reliability of the combination of the column 10 and the guide column 20 can be further guaranteed.

[0030] In addition, since the cross-sections of the guide column 20 and the column 10 are both rectangular, the problem of axial rotation of the guide column 20 on the column 10 can be avoided. At the same time, the interior of the column 10 is connected to the outside through the guide hole 13, so it is convenient to discharge the water flow entering the interior of the column 10. At the same time, the guide hole 13 is connected to the column 10 and the guide column 20, so the chimney effect can be used to facilitate the circulation of airflow inside the bracket, thereby reducing the corrosion of the inside of the bracket caused by water vapor.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
