Description

Technical Field

[0001] This utility model relates to the field of transport trolley technology, specifically a trolley for installing and disassembling cable reels. Background Technology

[0002] In the wire and cable industry, extrusion production lines need to use take-up equipment to wind cables onto reels. The take-up process involves the installation, disassembly, and movement of the take-up reels. Related auxiliary tools are used to cooperate with the take-up frame to complete the transfer and loading / unloading of the reels, so as to ensure the continuous operation of the production line and meet the production needs of subsequent cross-linking processes of semi-finished cables or the production needs of finished cable branching.

[0003] Currently, auxiliary tools used for loading, unloading, and moving take-up reels in the industry, while possessing basic transport capabilities, often employ fixed-direction wheels for their moving parts. This makes it difficult to flexibly adjust their position within the confined working spaces commonly found on extrusion production lines, hindering quick and accurate movement to the designated operating position on the take-up frame and increasing position calibration time. Furthermore, the reel placement areas of these tools are mostly planar structures, lacking specialized positioning and guiding designs. Reels are prone to shifting and wobbling, requiring manual effort to push and lift empty reels onto the tool or unload full ones, resulting in poor transport smoothness. Additionally, existing tools lack anti-reverse sliding structures for reel transport. When transporting empty reels, slight vibrations or external interference can cause the reels to slide backwards with the supporting components and fall, potentially damaging the reels and posing a risk of injuring operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a trolley for installing and disassembling take-up reels, thereby solving the technical problem that when an empty reel is transported, it is prone to sliding and falling off with the support components when encountering slight vibrations or external interference, which may damage the reel and pose a risk of injuring the operator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a trolley for installing and disassembling take-up reels, comprising: a body and casters, the casters being evenly distributed at the bottom of the body, and reel grooves being provided on both sides of the top of the body, with guide groups evenly distributed in the inner cavity of the reel grooves, the guide groups including rollers, and short shafts connected to both sides of the rollers, thereby improving the smoothness of the guide group when transporting the reel through the guidance of the rollers;

[0006] The roller is equipped with a locking mechanism, which includes two sets of connecting arms. Hollow columns are connected to the top two sides of each connecting arm. Locking arms are slidably connected to the outside of each hollow column. A spring is connected between the locking arm and the hollow column. A locking interface is provided on the outside of the connecting arm, and an assembly arm is connected to the outside of the locking interface. A slot adapted to the locking arm is provided on the outside of the short shaft. The connecting arm can be driven to move by the added assembly arm, thereby controlling the left or right locking arm to enter the slot inside the short shaft. This restricts the roller and the short shaft to rotate only in one direction, preventing the empty disc from slipping off when the roller is fed out.

[0007] Preferably, the top of the locking arm has a uniformly sloping design, and the outside of the locking arm is provided with a wear-resistant pad. The sloping design facilitates the locking arm to smoothly engage with the slot during the rotation of the short shaft, and the wear-resistant pad can enhance the wear resistance of the locking arm and extend its service life.

[0008] Preferably, the bottom of the inner cavity of the slot is connected to a slotted long rail, and a slider is slidably connected to the inner cavity of the slotted long rail. The slider is connected to the connecting arm, and the sliding of the slider in the slotted long rail can provide stable guidance for the movement of the connecting arm, ensuring that the connecting arm drives the locking arm to accurately align with the slot of the short shaft.

[0009] Preferably, the connecting arm is provided with a reinforcing arm on its exterior, and the locking mechanism is located on both sides of the inner cavity of the tool slot. Multiple sets of connecting arms are connected by an assembly arm, and the assembly arm controls the synchronous movement of multiple sets of connecting arms. The exterior of the vehicle body has a fixing hole, and the inner cavity of the fixing hole is provided with a pin for fixing the assembly arm. The reinforcing arm can enhance the structural strength of the connecting arm and prevent it from deforming under stress. The synchronous movement of multiple sets of connecting arms can realize the synchronous locking of multiple sets of guide groups, improving the locking stability. The pin fixing the assembly arm can ensure the structural stability of the locking mechanism during operation and prevent the assembly arm from accidentally shifting.

[0010] Preferably, the roller is provided with a rubber wheel on its outside, and the short shaft is set in the inner cavity of the tray groove through a bearing. The rubber wheel can increase the friction with the tray, prevent slippage during tray conveying, and at the same time play a buffering role to reduce tray wear; the bearing connection can reduce the friction when the short shaft rotates, further improving the smoothness of roller rotation.

[0011] Preferably, the exterior of the vehicle body is uniformly provided with reinforcing ribs, the top of the interior cavity of the vehicle body is provided with a push handle, the exterior of the push handle is provided with an anti-slip sleeve, and the universal wheel is connected to the vehicle body with a base. The reinforcing ribs can enhance the overall structural strength of the vehicle body to cope with the weight pressure of the tray; the anti-slip sleeve can increase the friction between the hand and the push handle, making it easier for the operator to push the trolley; the base can improve the firmness of the connection between the universal wheel and the vehicle body, ensuring the stability of the trolley during movement.

[0012] Compared with the prior art, this utility model provides a trolley for installing and disassembling cable reels, which has the following advantages:

[0013] This trolley for installing and removing take-up reels features casters at the bottom, allowing for flexible movement in confined spaces and easy placement on the take-up rack. It adapts to the needs of reel loading, unloading, and movement. The reel slots on the top of the trolley position the reels stably, while the guide rollers within the slots improve the smoothness of reel transport, making it easier to push empty reels on and unload full ones, avoiding the laborious manual handling. A locking mechanism on the rollers, driven by the assembly arm, engages with the short shaft slot, restricting unidirectional roller rotation and preventing empty reels from slipping due to reverse rotation during feed, reducing the risk of reel damage and injury. This trolley completely replaces traditional manual lifting and unloading, solving the problem of immobile take-up shafts, simplifying operations, improving efficiency, and reducing labor intensity, offering both practical value and economic benefits.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2A trolley for installing and removing take-up reels includes: a body 1 and casters 3. The casters 3 are evenly arranged at the bottom of the body 1. A transport belt assembly with rollers is also horizontally arranged on the upper part of the body 1. Reel grooves 2 are opened on both sides of the top of the body 1. Guide groups 4 are evenly arranged in the inner cavity of the reel grooves 2. The guide groups 4 include rollers 41. Short shafts 42 are connected to both sides of the rollers 41. The smoothness of the guide group 4 when transporting reels can be improved by the guidance of the rollers 41.

[0021] The roller 41 is provided with a locking mechanism 5. The locking mechanism 5 includes two sets of connecting arms 51. Hollow columns 52 are connected to the top of each connecting arm 51. Locking arms 54 are slidably connected to the outside of the hollow columns 52. A spring 53 is connected between the locking arms 54 and the hollow columns 52. A locking interface is provided on the outside of the connecting arm 51. An assembly arm 57 is connected to the outside of the locking interface. A slot that matches the locking arm 54 is provided on the outside of the short shaft 42. The connecting arm 51 can be driven to move by the added assembly arm 57, thereby controlling the left or right locking arm 54 to enter the slot inside the short shaft 42. This restricts the roller 41 and the short shaft 42 to rotate only in one direction, preventing the empty disc from slipping off when the roller 41 is fed out.

[0022] Please see Figure 3 and Figure 4 The top of the locking arm 54 has a uniformly sloping design, and the outside of the locking arm 54 is provided with a wear-resistant pad. The sloping design makes it easy for the locking arm 54 to smoothly enter the slot during the rotation of the short shaft 42. The wear-resistant pad can enhance the wear resistance of the locking arm 54 and extend its service life.

[0023] The bottom of the inner cavity of the slot 2 is connected to a slotted long rail 56. A slider 55 is slidably connected to the inner cavity of the slotted long rail 56. The slider 55 is connected to the connecting arm 51. The sliding of the slider 55 in the slotted long rail 56 can provide stable guidance for the movement of the connecting arm 51, ensuring that the connecting arm 51 drives the locking arm 54 to accurately align with the slot of the short shaft 42.

[0024] The connecting arm 51 is externally equipped with a reinforcing arm. The locking mechanism 5 is located on both sides of the inner cavity of the tool slot 2. Multiple sets of connecting arms 51 are connected by the assembly arm 57, and the assembly arm 57 controls the synchronous movement of multiple sets of connecting arms 51. The body 1 has a fixing hole on its exterior. The inner cavity of the fixing hole is equipped with a pin for fixing the assembly arm 57. The reinforcing arm can enhance the structural strength of the connecting arm 51 and prevent it from deforming under stress. The synchronous movement of multiple sets of connecting arms 51 can realize the synchronous locking of multiple sets of guide groups 4, improving the locking stability. The pin fixing the assembly arm 57 can ensure the structural stability of the locking mechanism 5 when it is working and prevent the assembly arm 57 from being accidentally displaced.

[0025] The roller 41 is equipped with a rubber wheel on its outside, and the short shaft 42 is set in the inner cavity of the tray groove 2 through a bearing. The rubber wheel can increase the friction with the tray, prevent slippage during tray conveying, and also play a buffering role to reduce tray wear. The bearing connection can reduce the friction when the short shaft 42 rotates, further improving the smoothness of the roller 41 rotation.

[0026] The exterior of the vehicle body 1 is uniformly provided with reinforcing ribs 11, and the top of the inner cavity of the vehicle body 1 is provided with a push handle 12. The push handle 12 is provided with an anti-slip sleeve. The universal wheel 3 is connected to the vehicle body 1 by a base 31. The reinforcing ribs 11 can enhance the overall structural strength of the vehicle body 1 to cope with the weight pressure of the tray; the anti-slip sleeve can increase the friction between the hand and the push handle 12, making it easier for the operator to push the trolley; the base 31 can improve the firmness of the connection between the universal wheel 3 and the vehicle body 1, ensuring the stability of the trolley during movement.

[0027] This method involves pushing an empty tray into the interior of the vehicle body 1 through the tray slot 2, pushing the vehicle body 1 to the pre-measured designated parking position relative to the take-up frame via the casters 3, pushing the empty tray into the take-up shaft, pushing it away from the vehicle body 1 for production, and pushing the vehicle body 1 to the designated position after production is completed. The tray filled with products is then pulled out and pushed away from the vehicle body 1 to the designated unloading point to remove the tray.

[0028] When the empty tray is placed into the interior of the vehicle body 1 through the tray slot 2, the smoothness of the guide group 4 is improved by the guide of the roller 41. At the same time, the connecting arm 51 is driven to move by the added assembly arm 57, and the locking arm 54 on the left or right side is controlled to enter the internal slot of the short shaft 42, thereby restricting the roller 41 and the short shaft 42 to rotate only in one direction. This prevents the empty tray from slipping off when the roller 41 rotates in the opposite direction when it is being fed out.
