Description

Technical Field

[0001] This utility model relates to the field of power engineering cable technology, specifically a parallel cable clamping device for power engineering. Background Technology

[0002] Electrical engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering projects that use electricity as a power source and energy source in various fields. It can also be understood as power transmission and transformation projects, urban lighting, and other projects closely related to residents' lives. With urban modernization, residents and urban electricity use all require the use of cables, which are the main transmission channels. When electrical engineers construct and renovate cable lines, they need to use cable fixing devices for electrical engineering to facilitate the fixing of cables.

[0003] A search revealed a Chinese patent with authorization number CN 213213056U, which discloses a cable fixing device for power grid engineering, including a connecting component and a fixing component. The connecting component is cross-shaped, and fixing components are connected to the top, bottom, left, and right sides of the connecting component. The fixing component includes a U-shaped fixing block, a fixing clamp, a movable clamp, a connecting plate, a limiting rod, and fasteners. One side wall of the U-shaped fixing block is fixed to the connecting component, and the fixing clamp is fixed to one side wall inside the U-shaped fixing block. The movable clamp is located inside the U-shaped fixing block on the side opposite to the fixing clamp. The side of the movable clamp away from the fixing clamp is connected to one side of the connecting plate, and one end of the limiting rod is symmetrically connected to the other side of the connecting plate.

[0004] The parallel cable clamping device for power engineering described in the above patent has the following shortcomings: it uses a cross-shaped structure, springs, and U-shaped fixing blocks to fix and limit multiple groups of cables. However, in actual use, because the fixing distance of each group of cables is different, this structure cannot be used to adjust the distance for fixing, resulting in low practicality. Furthermore, the fixing effect of cables using only U-shaped fixing blocks and screws is not good. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a parallel cable clamping device for power engineering, so as to solve the technical problem that in actual use, because the fixing distance of each group of cables is not the same, it is impossible to use this structure to adjust the distance for fixing, resulting in low practicality, and the fixing effect of cables by only using U-shaped fixing blocks and screws is not good.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a parallel cable clamping device for power engineering, comprising a first connecting block and a second connecting block, wherein multiple sets of cavities are formed inside the first connecting block and the second connecting block, multiple sets of first bolts that cooperate with the cavities are provided inside the first connecting block and the second connecting block, and a limit block is provided at one end of the first connecting block and the second connecting block respectively.

[0007] By adopting the above technical solution, when in use, external personnel place the first connecting block and the second connecting block between the two sets of cables. After placement, the limiting block set at one end of the first connecting block will lock one set of cables, and the sliding rod set at the bottom of the limiting block will prevent the limiting block from shifting while locking.

[0008] Then, multiple sets of second bolts are used to fix the limiting block and the first connecting block to clamp one set of cables. Then, the second connecting block is pulled by the protrusion inside the first connecting block and the connecting cavity inside the second connecting block to extend or reduce its lateral distance, so that the limiting block at one end of the second connecting block can lock the other set of cables.

[0009] Then, the limiting block is fixed by the second bolt to clamp the other set of cables. After the fixing is completed, the external staff need to use the cavities opened inside the first bolt, the first connecting block and the second connecting block to fix the first connecting block and the second connecting block to prevent them from moving during normal use and affecting the clamping effect of the cables.

[0010] The above structure allows for adjustment of the clamping length of the device according to the different fixed distances of each group of cables, making it highly practical. The first bolt, the limiting block, and the rubber pad ensure that the device will not fall off due to external factors during clamping.

[0011] Furthermore, the cavity is provided with an internal thread that meshes with the first bolt, and the limiting block is provided with a rubber pad.

[0012] By adopting the above technical solution, the mutual engagement of the internal thread and the first bolt ensures that external personnel can fix the first connecting block and the second connecting block by rotating the first bolt.

[0013] Furthermore, a locking cavity is provided between the limiting block and the first connecting block and the second connecting block, and the limiting block and the first connecting block and the second connecting block are fixed together by a second bolt.

[0014] By adopting the above technical solution, the locking cavity opened between the limiting block and the first connecting block and the second connecting block can fix the external cable and prevent it from dislodging during use.

[0015] Furthermore, two sets of sliding rods are fixed to the top of the limiting block, and a fixing block is provided at one end of each set of sliding rods.

[0016] By adopting the above technical solution, the two sets of sliding rods and fixing blocks can ensure that the fixing blocks will not fall to the outside and affect the fixing work.

[0017] Furthermore, the first connecting block has two sets of protrusions inside, and the second connecting block has two sets of connecting cavities that cooperate with the protrusions inside.

[0018] By adopting the above technical solution, the first connecting block and the second connecting block can be flexibly extended and retracted through two sets of protrusions and their corresponding connecting cavities.

[0019] Furthermore, one end of the first connecting block and the second connecting block is provided with a sliding cavity that cooperates with the sliding rod, and one end of the first connecting block and the second connecting block is provided with a threaded hole that cooperates with the second bolt.

[0020] By adopting the above technical solution, the cooperation between the sliding cavity and the sliding rod can ensure that the fixed block will not shift during sliding, thus preventing installation errors.

[0021] In summary, this utility model has the following beneficial effects: By placing a first connecting block and a second connecting block between two sets of cables, and then manually moving the first connecting block so that the protrusion inside the first connecting block can slide within the connecting cavity inside the second connecting block, the lateral length of the first and second connecting blocks can be increased or decreased. Then, a limiting block at one end of the first connecting block clamps one set of cables, and a second bolt is used for fixation to prevent cable dislocation. Multiple sets of first bolts further fix the positions of the first and second connecting blocks. This allows the clamping length of the device to be adjusted according to the different fixing distances of each set of cables, making it highly practical. The first bolts, limiting blocks, and rubber pads ensure that the cable will not fall off due to external factors during clamping. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A parallel cable clamping device for power engineering, such as Figures 1-4 As shown, it includes a first connecting block 1 and a second connecting block 2. The first connecting block 1 and the second connecting block 2 have multiple cavities 3 inside. When the first connecting block 1 and the second connecting block 2 are placed between two sets of cables by external personnel, one set of cables is locked by a limiting block 7 set at one end of the first connecting block 1. The limiting block 7 is prevented from shifting while locked by a sliding rod 9 set at the bottom end of the limiting block 7.

[0030] For example, the first connecting block 1 and the second connecting block 2 are provided with multiple sets of first bolts 4 that cooperate with the cavity 3. The first connecting block 1 and the second connecting block 2 are respectively provided with a limiting block 7 at one end. Then, multiple sets of second bolts 5 are used to fix the limiting block 7 and the first connecting block 1 to clamp one set of cables. Then, the second connecting block 2 is pulled by the protrusion 12 provided inside the first connecting block 1 and the connecting cavity 11 opened inside the second connecting block 2 to extend or reduce its lateral distance, so that the limiting block 7 provided at one end of the second connecting block 2 can lock the other set of cables.

[0031] For example, the cavity 3 is provided with an internal thread that meshes with the first bolt 4, the limiting block 7 is provided with a rubber pad 8, and a locking cavity 6 is provided between the limiting block 7 and the first connecting block 1 and the second connecting block 2. The limiting block 7 is fixed to the first connecting block 1 and the second connecting block 2 by the second bolt 5. Then, the limiting block 7 is fixed by the second bolt 5 to clamp another set of cables. After the fixing is completed, the external personnel need to use the cavities 3 opened inside the first bolt 4, the first connecting block 1 and the second connecting block 2 to fix the first connecting block 1 and the second connecting block 2 to prevent them from moving during normal use, which would affect the clamping effect of the cables.

[0032] For example, two sets of sliding rods 9 are fixed to the top of the limiting block 7. A fixing block 10 is provided at one end of each set of sliding rods 9. A sliding cavity that cooperates with the sliding rod 9 is opened at one end of the first connecting block 1 and the second connecting block 2 respectively. A threaded hole that cooperates with the second bolt 5 is opened at one end of the first connecting block 1 and the second connecting block 2 respectively. This allows the clamping and fixing length of the device to be adjusted according to the different fixing distances of each set of cables. It is highly practical. The first bolt 4, the limiting block 7 and the rubber pad 8 can ensure that the device will not fall off due to external factors during clamping.

[0033] The working principle of this utility model is as follows: When in use, the first connecting block 1 and the second connecting block 2 are placed between the two sets of cables by external personnel. After they are placed, the limiting block 7 set at one end of the first connecting block 1 is used to lock one set of cables, and the sliding rod 9 set at the bottom of the limiting block 7 is used to prevent the limiting block 7 from shifting while locking.

[0034] Then, multiple sets of second bolts 5 are used to fix the limiting block 7 and the first connecting block 1 to clamp one set of cables. Then, the second connecting block 2 is pulled by the protrusion 12 inside the first connecting block 1 and the connecting cavity 11 inside the second connecting block 2 to extend or reduce its lateral distance, so that the limiting block 7 at one end of the second connecting block 2 can lock the other set of cables.

[0035] Then, the limiting block 7 is fixed by the second bolt 5 to clamp another set of cables. After the fixing is completed, the external staff need to use the cavity 3 opened inside the first bolt 4, the first connecting block 1 and the second connecting block 2 to fix the first connecting block 1 and the second connecting block 2 to prevent them from moving during normal use, which would affect the clamping effect of the cables.

[0036] The above structure allows for adjustment of the clamping length of the device according to the different fixed distances of each group of cables, making it highly practical. The first bolt 4, the limiting block 7, and the rubber pad 8 ensure that the device will not fall off due to external factors during clamping.
