Description

Technical Field

[0001] The utility model relates to a suspension equipment for wires or cables, in particular to a cable bracket for road and bridge construction. Background Art

[0002] During road and bridge construction, some temporary power cables are directly placed on the road surface or bridge deck, and some use brackets to hang the cables on one side of the road surface or bridge deck to make the construction safer.

[0003] The applicant applied for a bridge deck cable bracket on November 29, 2023 (publication number CN 221263312 U, application number 202323231073.5), which includes a sleeve with a hole at the bottom for sleeving the end of the embedded steel bar of the bridge deck guardrail. The top end of the sleeve is fixedly provided with an L-shaped bracket; a hanging ring is arranged at the bottom of the horizontal section of the L-shaped bracket, and a space for the cable to pass through is formed by enclosing between the hanging ring and the horizontal section; the temporary power cable passes through the hanging ring, and the L-shaped bracket cooperates with the hanging ring to support the temporary power cable.

[0004] As Figure 5 shown, when the bracket with the above structure is in use, if the two ends of the hanging ring are welded to the horizontal section of the L-shaped bracket, an S-hook is needed when hanging the cable. The upper end of the S-hook is hoisted on the hanging ring, and the lower end is used to hang the cable. If the two ends of the hanging ring are detachably connected to the horizontal section of the L-shaped bracket by bolts and nuts (as shown in Figure 2 of CN 221263312 U), then the nut can be unscrewed to separate one end of the hanging ring from the horizontal section of the L-shaped bracket, put the cable in and then fix it. This method can avoid using an S-hook, but it needs to be disassembled and assembled.

[0005] In the actual operation process, in addition to the inconvenience in the above use method, in some sites, there is also a problem that there is no steel bar on the road surface or bridge deck to insert for installing the bracket. To further solve the above problems, the applicant applies for the present utility model for the bracket further improved in practice. Summary of the Utility Model

[0006] The problem to be solved by the present utility model is the inconvenience in using the existing cable bracket, and provides a cable bracket that is applicable to various occasions and is convenient for cable hanging.

[0007] The technical solution for achieving the purpose of the present utility model is a cable bracket for road and bridge construction, which includes a base, a column, an extension rod and a hook. The column is vertically arranged above the base, the extension rod and the column form a bent shape, and the hook is arranged below the extension rod.

[0008] The base includes a sleeve portion and a chassis portion. The chassis portion is disposed below the sleeve portion, and the outer diameter of the chassis portion is greater than that of the sleeve portion. The chassis portion is provided with screw holes along the circumferential direction, and the screw holes are located outside the sleeve portion.

[0009] The hook includes a main body and a blocking portion. The main body includes two rods forming a V shape, namely a fixed rod and a non-fixed rod. The upper end of the fixed rod close to the column is fixed below the extension rod.

[0010] The blocking portion is disposed at the end of the non-fixed rod of the main body. A hanging opening is formed between the top of the blocking portion of the hook and the extension rod. The setting of the blocking portion can well play the role of preventing the cable from slipping out.

[0011] The included angle between the blocking portion of the hook and the non-fixed rod of the main body is 60° - 120°, preferably 85° - 90°.

[0012] Furthermore, the hook further includes a guiding portion. The guiding portion extends from the end of the blocking portion towards the lower right. The gap between the guiding portion and the main body is greater than the outer diameter of the cable to be hung. The blocking portion and the guiding portion and the main body form a cable anti-slip portion. The setting of the guiding portion can help the cable enter the hook along the guiding portion when hanging the cable. Moreover, during the operation, in case of strong wind or other pulling situations, the cable will be subjected to a pulling force and enter the anti-slip portion formed by the blocking portion, the guiding portion and the main body, and is not easily detached from the hook.

[0013] The ratio of the height of the column to the height of the base is 1.5 - 4:1.

[0014] For safety and insulation, the extension rod and the hook are made of insulating materials, or the surfaces of the extension rod and the hook are coated with insulating materials.

[0015] The chassis portion, the sleeve portion and the column are coaxial. A hole is provided in the center of the sleeve portion and the chassis portion, and the hole penetrates the sleeve portion and the chassis portion.

[0016] The utility model has positive effects:

[0017] (1) For the cable support of the utility model, a hook is provided below the extension rod. The cable to be hung is directly hung on the hook through the hanging opening, without the need to use an auxiliary S-shaped hook, nor the need for disassembly and assembly operations on the hook. Not only is it convenient to hang the cable, but it is also very convenient to remove the cable.

[0018] (2) The base of the cable support of the utility model is a dual-purpose base. In addition to the sleeve portion, the base is also provided with a chassis portion, and screw holes are reserved on the chassis portion. In some positions without reserved steel bars, the cable support can be temporarily fixed on the road surface or the bridge surface through bolts. Therefore, the cable support of the utility model has a wider application scenario. Description of the Drawings

[0028] (Embodiment 1)

[0029] SeeFigure 1 For the cable support used in road and bridge construction in this embodiment, it includes a base 1, a column 2, an extension rod 3 and a hook 4. The base 1 and the column 2 are coaxial. The extension rod 3 extends horizontally or obliquely upward from the top of the column 2, forming a bent shape with the column 2. The hook 4 is arranged below the extension rod 3, and a hanging opening 5 is formed between the hook 4 and the extension rod 3. The cable to be suspended can be put into the hook 4 through the hanging opening 5, so as to be suspended on the support.

[0030] The base 1 is cylindrical, and a coaxial hole is provided in the center of the base 1 for inserting into the steel bars reserved on the bridge deck or the columns reserved on other road and bridges, so that the cable support stands upright on the road and bridge deck. In this embodiment, the height of the base 1 is 30 cm.

[0031] The column 2 is vertically arranged above the base 1. The ratio of the height of the column 2 to the height of the base 1 is 1.5 - 4:1. In this embodiment, the height of the column 2 is 50 cm.

[0032] The extension rod 3 includes a connecting section 3-1 and a straight section 3-2, and the included angle between the straight section 3-2 of the extension rod 3 and the column 2 is 90° - 120°.

[0033] The hook 4 includes a main body 4-1, a blocking part 4-2 and a guiding part 4-3. The main body 4-1 includes two rods forming a V shape, namely a fixed rod 4-1-1 and a non-fixed rod 4-1-2. The upper end of the fixed rod 4-1-1 of the main body 4-1 close to the column 2 is fixed below the straight section 3-2 of the extension rod 3. For example, Figure 1 in terms of this, the column 2 is located on the right side of the hook 4, and the upper end of the right fixed rod 4-1-1 of the main body 4-1 of the hook 4 is fixed to the extension rod 3.

[0034] The blocking part 4-2 is arranged at the end of the non-fixed rod 4-1-2 of the main body 4-1, and the included angle between the blocking part 4-2 and the non-fixed rod of the main body 4-1 is 60° - 120°, preferably 85° - 90°.

[0035] The guiding part 4-3 extends obliquely downward to the right from the end of the blocking part 4-2, and the gap between the guiding part 4-3 and the main body 4-1 is larger than the outer diameter of the cable to be suspended. The blocking part 4-2 and the guiding part 4-3 and the main body 4-1 form a cable anti-slip part.

[0036] A hanging opening 5 is formed between the top of the blocking part 4-2 of the hook 4 and the straight section 3-2 of the extension rod 3. The size of the hanging opening 5 ensures that the cable can pass through.

[0037] Insulation is required between the cable and the support. To solve the insulation problem, one solution is that the extension rod 3 and the hook 4 are partially made of insulating materials such as plastics, and another solution is that the surfaces of the extension rod 3 and the hook 4 are both coated with insulating materials such as insulating sleeves.

[0038] The advantages of the cable support in this embodiment are as follows: After installing the base 1 on the ground, when it is necessary to hang the cable, put the cable into the hook 4 from the hanging opening 5, and the hanging operation is completed; during the operation, in case of strong wind or other pulling situations, when the cable is subjected to tension, it will enter the anti-slip part formed by the blocking part 4-2 and the guiding part 4-3 and the main body 4-1, and it is not easy to slip out of the hook 4; when it is necessary to remove the cable, just remove the cable from the hook 4.

[0039] (Embodiment 2)

[0040] See Figure 2 and Figure 4 For this cable support in this embodiment, the rest is the same as that in Embodiment 1, and the difference lies in:

[0041] The base 1 includes a sleeve part 1-1 and a chassis part 1-2. The chassis part 1-2 is arranged below the sleeve part 1-1, and the outer diameter of the chassis part 1-2 is larger than that of the sleeve part 1-1.

[0042] The chassis part 1-2, the sleeve part 1-1 and the column 2 are coaxial.

[0043] A hole 1-3 is provided in the center of the sleeve part 1-1 and the chassis part 1-2, and the hole 1-3 penetrates through the sleeve part 1-1 and the chassis part 1-2.

[0044] Threaded holes 1-2-1 are arranged along the circumferential direction of the chassis part 1-2, and the threaded holes 1-2-1 are located outside the sleeve part 1-1.

[0045] After adding the chassis part 1-2 to the base 1, the cable support can be temporarily fixed on the road surface or bridge surface by bolts, so it can be applied to scenarios without pre-set steel bars.

[0046] (Embodiment 3)

[0047] See Figure 3 For this cable support in this embodiment, the rest is the same as that in Embodiment 2, and the difference lies in: The hook 4 only includes the main body 4-1 and the blocking part 4-2. The guiding part 4-3 is not provided. It is convenient when there is no guiding part 4-3 for placing the cable, but the hook structure is simpler, and only including the blocking part 4-2 can well play the role of blocking the cable from slipping out.
