Description

Technical Field

[0001] The present application relates to the field of shipbuilding, and in particular to a cable reel. Background Art

[0002] Cable laying is a crucial step in the shipbuilding process. Since a large number of cables are required for connections and power supply, laying cables is a massive undertaking, requiring extremely high efficiency and safety. To efficiently complete cable laying tasks, cable reels are essential equipment, offering significant advantages and benefits. First, they can quickly and neatly deploy cables, adapting to the complex internal structures and confined spaces of ships, significantly improving cable laying efficiency. Second, they neatly wind cables, preventing damage during storage and transportation, while also protecting them from moisture, corrosion, and mechanical damage, effectively safeguarding the performance and lifespan of the ship's electrical systems. By controlling the laying speed and tension, cable reels effectively prevent kinking, entanglement, or breakage, reducing construction risks and avoiding safety incidents caused by cable problems. Furthermore, cable reels ensure a neat and standardized cable laying path, minimizing the risk of signal interference and electrical performance degradation, and ensuring the stable operation of the ship's electrical systems.

[0003] However, existing cable reels have significant limitations. First, the cable drums used in shipbuilding vary in size, while existing cable reels are typically fixed in size and cannot accommodate reels of varying sizes. This can require the use of multiple cable reels of varying sizes during construction, increasing equipment procurement costs and required storage space. If the cable reels at the construction site do not match the cable reels, work must be halted and an appropriate cable reel must be dispatched, resulting in wasted time and increased costs. Furthermore, the mixing of cable reels of varying sizes on the construction site can significantly inconvenience management and construction, increasing the risk of errors in the workflow and delaying construction. Summary of the Invention

[0004] The present invention provides a cable reel that can adjust the distance between sliders and the width of an adjustment seat by moving sliders on a slide rail. This allows cable reels of varying widths to be mounted on the reel. Furthermore, the reel mounts the cable reel on a rotatable rocker arm, allowing the height of the reel's center to be adjusted, thereby accommodating reels with varying bottom diameters.

[0005] The present application provides a cable reel, comprising a bracket and an adjustment seat. A slide rail is fixedly provided above the bracket. The adjustment seat comprises two parallel sliders, a stand fixedly provided above the sliders, and a rocker arm provided on the side of the stand. The sliders are slidably connected to the slide rails. The first end of the rocker arm is rotatably connected to the side of the stand, and a positioning hole is provided at the second end of the rocker arm, in which a cable reel shaft is provided. The cable reel shaft is divided into a first shaft section and a second shaft section along its length direction. The cross section of the first shaft section is circular, and the cross section of the second shaft section is polygonal. The first shaft section is mounted in cooperation with the positioning hole.

[0006] In an implementable solution, a first driver is provided between the two sliders for driving the two sliders to slide along the slide rail.

[0007] In one feasible solution, the first drive includes a plurality of hydraulic push rods, each of which is fixedly connected to the two slides.

[0008] In one feasible solution, a winch shaft parallel to the slide rail is set between the two vertical frames, one end of the winch shaft is fixedly connected to the first winch, and the other end is slidably connected to the second winch. The outer sides of the first winch and the second winch are respectively wrapped with towing ropes for towing the cable drum.

[0009] In one feasible solution, the cable drum shaft and the winch shaft are driven by a belt.

[0010] In one feasible solution, a second driver is provided on the rocker arm, and the second driver is connected to the cable drum shaft in power so as to drive the cable drum shaft to rotate.

[0011] In an implementable solution, a third driver is provided between the slider and the corresponding rocker arm, and both ends of the third driver are rotatably connected to the slider and the second end of the rocker arm, respectively, for driving the rocker arm to rotate around the first end.

[0012] In one feasible solution, rollers are provided at the bottom of the bracket to assist in moving the cable reel.

[0013] In one feasible solution, a support base with adjustable height is provided at the bottom of the bracket for supporting and fixing the cable reel.

[0014] In one feasible solution, a stop block is provided on the upper surface of the bracket for limiting the position of the cable reel.

[0015] Compared with the prior art, the beneficial effects of this application include at least:

[0016] The present application provides a cable reel that can change the distance between sliders by moving the sliders on the slide rails, thereby changing the width of the adjustment seat. Therefore, cable reels of different widths can be installed on the cable reel of the present application. Furthermore, the cable reel of the present application is provided with a rotatable rocker arm, and the cable reel is mounted on the rocker arm. Since the height of the cable reel center can be changed by rotating the rocker arm, the cable reel of the present application can accommodate cable reels with different bottom diameters. Because the cable reel of the present application can accommodate cable reels of different specifications, there is no need to prepare multiple cable reels in advance at the work site, which reduces space usage and effectively avoids the situation where the cable reel at the work site does not match the specifications of the cable reel, thereby improving work efficiency and reducing costs.

[0017] Furthermore, the cable reel of the present application is equipped with a winch and a towing rope, which can drag the cable reel for installation. In traditional methods, the operator usually manually moves the cable reel to a designated position on the cable reel. However, the cable reel is usually large in size and weight, requiring a lot of manpower, and there are certain personal safety risks during the installation process. In contrast, the cable reel of the present application can drag the cable reel to the designated position without the need for direct human participation in the entire process, greatly improving the efficiency and accuracy of the cable reel installation process and effectively reducing personal safety accidents.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0026] like Figure 1 As shown, the present application provides a cable reel, comprising a bracket 1 and an adjustment seat. A slide rail 101 is fixedly provided above the bracket 1. The adjustment seat comprises two parallel sliders 201, a stand 202 fixedly provided above the slider 201, and a rocker arm 203 provided on the side of the stand 202. The slider 201 is slidably connected to the slide rail 101. The first end of the rocker arm 203 is rotatably connected to the side of the stand 202, and a positioning hole 231 is provided at the second end of the rocker arm 203, in which a cable reel shaft 232 is provided. The cable reel shaft 232 can be divided into a first shaft section and a second shaft section along its own length direction, wherein the cross section of the first shaft section is circular, and the cross section of the second shaft section is polygonal, and the first shaft section is mounted in conjunction with the positioning hole 231.

[0027] like Figure 2 As shown, a first driver 301 may be provided between the two sliders 201 for driving the two sliders 201 to slide along the slide rail 101. Specifically, the first driver may include a plurality of hydraulic push rods 311, for example, two or four hydraulic push rods, wherein the ends of half of the hydraulic push rods 311 are fixedly connected to one slider 201, and the ends of the other half of the hydraulic push rods 311 are fixedly connected to the other slider 201. Figure 4As shown, the first actuator 301 also includes a hydraulic pump 312 and a reversing valve 313. The hydraulic pump 312 is connected to each hydraulic push rod 311 to provide power to the hydraulic push rods 311. The reversing valve 313 ensures that each hydraulic push rod 311 receives the same hydraulic medium flow rate, thereby ensuring that the first actuator 301 can apply the same amount of force to the two sliders 201, allowing the two sliders 201 to always move synchronously in opposite directions and the same distance. In addition, to reduce the overall weight of the cable reel and reduce potential maintenance problems, the cable reel can be equipped with no hydraulic oil tank. When hydraulic oil needs to be replenished, it can be connected to an external oil pipeline through the reversing valve 314. Alternatively, the first actuator 301 may include multiple electric push rods, which are connected to the slider 201 in the same manner and function as the hydraulic push rods 301. The specific form of the first actuator 301 is not limited in this application; it only needs to enable the slider 201 to move along the slide rail 101.

[0028] For the second shaft section of the cable drum shaft 232, as shown in FIG. Figure 1 As shown, its cross section can be a quadrilateral, and can also be set to a pentagon or hexagon, etc., and there are no excessive restrictions here. The polygonal cross section helps the second shaft segment to form a tight fit with the shaft hole 231 to prevent relative sliding between the components, and compared with the circular cross section, the polygonal cross section provides more contact surface, which helps to achieve uniform distribution of load and reduce local stress concentration, thereby improving the strength and durability of the connection, increasing the torque transmission capacity and extending the service life of the cable drum shaft 232. The cross section of the second shaft segment is smaller than the positioning hole 231, so that the second shaft segment can be passed through the positioning hole 231 during installation. Figure 1 As shown, the cable drum 4 is provided with an axial hole 401 at its center, which mates with the cross-sectional shape of the second shaft segment of the cable drum shaft 232. During use, the cable drum 4 is moved into position, aligning the axial hole 401 with the positioning hole 231. The cable drum shaft 232 is then inserted through the positioning hole 231, with the second shaft segment first passing through the positioning hole 231 and mating with the axial hole 401 of the cable drum 4. This allows the cable drum shaft 232 and the cable drum 4 to achieve normal transmission.

[0029] like Figure 2 As shown, a winch shaft 204 parallel to the slide rail 101 is set between the two stands 202, one end of the winch shaft 204 is fixedly connected to the first winch 241, and the other end is slidably connected to the second winch 242. Grooves are respectively set on the outer sides of the first winch 241 and the second winch 242, and a drag rope 243 is wound in the groove for dragging the cable drum.

[0030] Specifically, if Figure 2As shown, the capstan shaft 204 and the second capstan 242 can be connected by a spline, that is, the capstan shaft 204 is provided with an external spline on the outer side of one end close to the second capstan, and a connecting hole with a corresponding internal spline is provided at the center of the second capstan 242, as shown in FIG. Figure 3 As the distance between the two sliders 201 changes, the capstan shaft 204 can slide relative to the connection hole of the second capstan 242, ensuring that the capstan shaft 204 and the second capstan 242 can always transmit power normally. Alternatively, one end of the capstan shaft 204 can be fixedly connected to the second capstan 242, while the other end can be slidably connected to the first capstan 241, which is not a limitation here.

[0031] like Figure 1 and Figure 2 As shown, a second driver 302 can be provided on the rocker arm 203. The second driver 302 is in power connection with the cable drum shaft 232 to drive the cable drum shaft 232 to rotate. Specifically, a motor base can be fixedly provided on the outside of the rocker arm 203, and the second driver 302 is bolted to the motor base. The second driver 302 is then connected to the cable drum shaft 232 via a gear reduction box.

[0032] When using, such as Figure 2 As shown, first, the position of the slider 201 is moved according to the specifications of the cable drum 4 used, so that there is an appropriate distance between the two rocker arms 203, which can accommodate the cable drum 4 and can smoothly install the cable drum shaft 232. Then, the drag rope 243 is connected to the cable drum 4. Preferably, the transmission between the cable drum shaft 232 and the winch shaft 204 can be achieved through a belt 244, so that there is no need to set up an additional drive specifically for the winch shaft 204, which helps to simplify the structure and reduce costs. At this time, the second drive 302 is started, the cable drum shaft 232 starts to rotate and drives the winch shaft 204 to rotate synchronously through the belt, and the drag rope 243 will pull the cable drum 4 to move in the direction close to the cable drum shaft 232. Preferably, as Figure 1 As shown, a ramp 104 can be provided on the side of the bracket 1 away from the stand 202 so that the cable drum 4 can be smoothly rolled onto the bracket 1. Figure 2 As shown, a stop block 211 can also be provided on the upper surface of the bracket 1 to limit the cable reel 4. Preferably, the stop block 211 can also be provided in a movable style. When the cable reel 4 rolls into place, the stop block 211 forms a limiting effect on the cable reel 4. At this time, the shaft hole 401 of the cable reel 4 is aligned with the positioning hole 231. Then, the cable reel shaft 232 is disconnected from the winch shaft 204, and then the cable reel shaft 232 is inserted into the shaft hole 401 so that the second shaft section is matched with the shaft hole 401, completing the connection between the rocker arm 203 and the cable reel 4. Finally, the rocker arm 203 is rotated to raise the positioning hole 231. After the distance between the lower end of the cable reel 4 and the upper surface of the bracket 1 reaches the preset standard, the entire installation process is completed. Specifically, as Figure 2 As shown, a third actuator 303 can be provided between the slider 201 and the corresponding rocker arm 203. The third actuator 303 has two ends rotatably connected to the slider 201 and the second end of the rocker arm 203, respectively, to drive the rocker arm 203 to rotate about its first end. The third actuator 303 can be an electric push rod or a hydraulic push rod and has a locking function to ensure that the rocker arm 203 is securely fixed after being rotated into position, preventing the cable reel 4 from shaking.

[0033] In summary, the cable reel of the present application can change the width of the adjustment seat by moving the slider on the slide rail to change the distance between the sliders, so that cable reels of different widths can be installed on the cable reel of the present application. In addition, the cable reel of the present application is provided with a rotatable rocker arm, and the cable reel is mounted on the rocker arm. Since the height of the cable reel can be changed by rotating the rocker arm, the cable reel of the present application can adapt to cable reels with different bottom diameters. Since the cable reel of the present application can adapt to cable reels of different specifications, there is no need to prepare multiple cable reels in advance at the work site, which reduces space occupation and effectively avoids the situation where the cable reel at the work site does not match the specifications of the cable reel, thereby improving work efficiency and reducing costs.

[0034] Furthermore, the cable reel of the present application is equipped with a winch and a towing rope, which can drag the cable reel for installation. In traditional methods, the operator usually manually moves the cable reel to a designated position on the cable reel. However, the cable reel is usually large in size and weight, requiring a lot of manpower, and there are certain personal safety risks during the installation process. In contrast, the cable reel of the present application can drag the cable reel to the designated position without the need for direct human participation in the entire process, greatly improving the efficiency and accuracy of the cable reel installation process and effectively reducing personal safety accidents.

[0035] In one embodiment, if Figure 1 As shown, rollers 102 can be provided at the bottom of the bracket 1 to assist in moving the cable reel. Furthermore, some or all of the rollers 102 can have a steering function, thereby facilitating steering of the cable reel during movement. A locking device can also be provided on the rollers 102 to prevent the cable reel from moving unnecessarily during use.

[0036] In one embodiment, if Figure 1 As shown, the bottom of the bracket 1 can be provided with a height-adjustable support base 103 for supporting and securing the cable reel. In particular, if the ground where the cable reel is located is uneven, the height of the support base 103 can be adjusted appropriately to compensate, ensuring the correct posture of the cable reel. Preferably, at least four support bases 103 are provided on the bottom of the bracket 1.

[0037] In one embodiment, the cable reel further includes a controller (not shown). The controller can be signal-connected to the first driver 301, the second driver 302, and the third driver 303 to control the movement of each driver. With the controller, operators can remotely control the entire process of the cable reel, from installation to use. This makes installation and use of the cable reel more precise, further saves manpower and resources, and reduces the risk of personal injury accidents.

[0038] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
