Description

TECHNICAL FIELD

[0001] The utility model relates to cable laying auxiliary equipment technical field, concretely relates to a movable steel cable insulation pulley support. BACKGROUND

[0002] In the cable laying process, the safety and efficient laying of the cable is very important. The pulley plays a key role in it, which can effectively guide the movement of the cable, greatly reducing the friction between the cable and the ground or other objects, thereby protecting the cable from damage. However, the existing cable pulley support does have many unsatisfactory aspects, which seriously affects the smooth progress of the cable laying work.

[0003] First of all, the existing cable pulley support structure is complex. The complex structure not only increases the difficulty and cost of manufacturing, but also makes the installation and disassembly process cumbersome. In the construction site, workers often need to spend a lot of time and effort to assemble these complex supports, which undoubtedly reduces the construction efficiency.

[0004] Secondly, poor stability is another disadvantage of the existing cable pulley support. In the process of cable laying, the weight of the cable is usually large, plus the pulling force in the dragging process, if the stability of the pulley support is insufficient, it is easy to incline or even collapse. This not only causes damage to the cable, but also threatens the safety of the construction personnel. The reason for poor stability may be that the design of the support is unreasonable, or the strength of the material is not enough. In either case, the structure and material of the existing cable pulley support need to be improved to improve its stability.

[0005] Complicated operation is also a problem of the existing cable pulley support. Some cable pulley supports need to be adjusted and operated in multiple steps during use to adapt to cables of different diameters and different construction environments. This not only increases the labor intensity of workers, but also is prone to operation errors, affecting the construction quality.

[0006] In addition, the inconvenience of movement is also a disadvantage of the existing cable pulley support. In the process of cable laying, the pulley support often needs to be moved according to the construction progress and site changes. However, some existing cable pulley supports are large in size and heavy in weight, making it difficult to move. Some supports even need to be moved with the help of mechanical equipment, which not only increases the construction cost, but also affects the construction progress.

[0007] In summary, the existing cable pulley support has the problems of complex structure, poor stability, complicated operation and inconvenient movement, which cannot meet the needs of actual construction. UTILITY MODEL CONTENT

[0008] The utility model provides a mobile steel cable insulation pulley support to solve the above -mentioned problems in prior art.

[0009] In order to realize the above-mentioned purpose, the utility model provides the following technical scheme:

[0018] Further, the limiting plate is in an arc shape or a U shape.

[0019] Further, the pulley is an integrally formed structure made of hard plastic.

[0020] The utility model has the following advantages:

[0021] First, the sliding groove circumferentially provided on the outer peripheral wall of the pulley provides a specific accommodating space for the cable, when the cable is dragged, the cable can only move along the track of the sliding groove, which ensures the accuracy of the moving direction of the cable, avoids the cable from deviating or winding during the movement process, and helps the orderly cable laying.

[0022] Second, the cable abuts in the sliding groove, and the movement of the cable is driven by the rotation of the pulley, the sliding friction between the cable and the ground or other rough objects is converted into the rolling friction between the cable and the relatively smooth surface of the sliding groove.

[0036] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Example 1

[0038] like Figures 1 to 5 As shown, a movable steel cable insulated pulley bracket according to the first aspect of this utility model includes a support assembly, a pulley seat 3, and a pulley 4. One end of the support assembly is fixed to the ground or a workbench, and the other end of the support assembly is provided with a pulley seat 3. The pulley 4 is axially mounted on the pulley seat 3 via an axle 301. A groove 401 is provided on the outer peripheral wall of the pulley 4 along the circumference of the pulley 4. The groove 401 is used to accommodate the cable 10, and the cable 10 abuts against the groove 401. When the cable 10 is dragged, the cable 10 drives the pulley 4 to rotate.

[0039] The support assembly includes a bracket 1, a support 2, and a positioning element 5. Two sets of brackets 1 are arranged at intervals relative to each other, and the middle of the two sets of brackets 1 are connected by the positioning element 5. The top of the support 2 is connected to the pulley seat 3, and the bottom of the support 2 is connected to the top of the two sets of brackets 1. The support 2 and the positioning element 5 are arranged in parallel. The support 2 plays an important role in transmitting force and connecting different components in the entire support assembly.

[0040] The two sets of supports and positioning members are integrally formed of iron or steel, which ensures that the supports have high strength and stability and can withstand the tension and pressure generated by the cable during movement. The positioning member is used to connect the middle portions of the two sets of supports, and through the fixed connection of the two sets of supports, the stability of the entire support assembly is enhanced, preventing the supports from deforming or shifting during use. At the same time, the positioning member and the supports adopt the same integrally formed structure of iron or steel, ensuring the reliability of the overall structure. The positioning member can be a bolt or a pin shaft. The pulley is integrally formed of hard plastic, has good insulation performance, and can effectively prevent electrical accidents during cable laying. Even if the cable leaks, the pulley can prevent current conduction and avoid electric shock accidents, improving the safety of construction, especially suitable for cable laying projects in various complex environments, including places that may be wet or electrically disturbed. Hard plastic also has the advantage of being lightweight. The support is usually made of a metal plate with a certain thickness and strength, and is usually rectangular or square in shape. The size matches the connection part of the pulley seat and the support. The pulley seat is located at one end of the support assembly and is the installation base of the pulley. The pulley seat is made of strong metal material and has enough strength to support the rotation of the pulley and the pressure applied by the cable. Its shape is designed to match the pulley, with holes on both sides for installing the wheel shaft and a stable connection with the support at the top. The pulley is installed on the pulley seat through the wheel shaft and can rotate freely. The pulley is integrally formed of hard plastic, which not only has good insulation performance and can effectively prevent electrical accidents, but also has a relatively light texture, which helps to reduce the weight of the entire device and facilitate movement. The outer peripheral wall of the pulley is provided with a sliding groove along the circumference. The shape and size of the sliding groove are designed according to the specifications of the cable, which is used to accommodate the cable. When the cable is in use, it abuts against the sliding groove. When pulling the cable, the friction between the cable and the sliding groove drives the pulley to rotate, thereby achieving smooth movement of the cable and reducing direct friction between the cable and other objects, protecting the cable sheath.

[0041] Working principle: When performing cable laying or moving operations, first fix the support assembly on the ground or workbench. Place the cable 10 in the sliding groove 401 of the pulley 4, and the cable 10 is in close contact with the sliding groove 401. When pulling the cable 10, the pulley 4 will rotate around the wheel shaft 301 due to the friction between the cable 10 and the sliding groove 401, thereby converting the sliding friction of the cable 10 into the rolling friction of the pulley 4, greatly reducing the resistance during movement of the cable 10. The hole-like structure formed by the limiting plate 8 and the sliding groove 401 limits the cable 10, ensuring that the cable 10 does not come off the sliding groove 401, allowing the cable 10 to move stably in the predetermined direction.

[0042] The mobile steel cable insulation pulley support is suitable for various cable laying projects, including but not limited to power cable laying, communication cable laying in construction projects, cable wiring in industrial plants, and outdoor cable erection projects. Whether on indoor flat ground, workbench, or outdoor land, cement ground, and other different working environments, it can provide effective support and guidance for cable movement.

The two groups of supports 1 and the positioning piece 5 are integrally formed structures made of iron or steel. The bottom of the two groups of supports 1 is fixedly provided with a cross bar 9, wherein the cross bar 9 and the positioning piece 5 are parallelly arranged, the cross bar 9 further increases the bottom support area of the support 1, and improves the stability of the whole support assembly, especially when a larger pulling force is encountered or when working on uneven ground, the support can be effectively prevented from falling.
