Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a copper busbar take-up and untake-down fixture. Background Technology

[0002] Grounding copper busbars, as key conductive components in electrical systems, are made of highly conductive copper. Thanks to their excellent conductivity, superior corrosion resistance, and good mechanical strength, they play an indispensable and fundamental role in numerous fields such as power transmission, industrial automation, and building electrical safety. They are core infrastructure for ensuring the safe operation of electrical systems and achieving effective lightning protection and interference suppression. Their standardized and reliable installation is crucial for maintaining personal safety and the long-term stable operation of equipment.

[0003] Currently, the main method for laying and winding grounding copper busbars is manual traction. This means that workers manually wind and unwind the copper busbars to complete the laying process. During winding, workers typically need to operate manually or use simple, general-purpose tools to handle the rolled or segmented copper busbars. During laying, a segmented laying method is usually adopted, where pre-fabricated copper busbar units are first manually transported to the installation location, and then workers connect and secure each segment individually.

[0004] However, the process of manually operating or using simple tools to unfold, retrieve, position and install copper busbars is cumbersome, laborious and time-consuming, which greatly restricts the overall construction progress and makes it difficult to meet the demand of modern electrical engineering for efficient installation. Utility Model Content

[0005] In view of this, the present invention provides a copper busbar take-up and put-down fixture to solve the problems of the cumbersome, laborious and time-consuming process of the existing copper busbar take-up and put-down scheme.

[0006] The copper busbar take-up and undo fixture provided by this utility model includes a mounting body, a take-up and undo roller, and an operating rod. The mounting body is fixedly installed on the ground; the take-up and undo roller is rotatably mounted on the mounting body, with the axis of the take-up and undo roller parallel to the ground; one end of the operating rod along its length is mounted on the outer peripheral wall of the take-up and undo roller, and the other end extends radially away from the take-up and undo roller; wherein, an external force is applied to the operating rod to drive the take-up and undo roller to rotate around its axis, thereby realizing the rapid take-up or undo of the copper busbar.

[0007] Beneficial effects: By setting up a mounting body fixed to the ground and a take-up / unwinding roller rotatably mounted on the mounting body, the construction worker can drive the take-up / unwinding roller to rotate by driving an operating lever, thus achieving continuous and smooth winding or unwinding of the copper busbar, since the axis of the take-up / unwinding roller is parallel to the ground. This replaces the traditional manual traction, winding, or unwinding methods, allowing the construction worker to drive the take-up / unwinding roller to rotate with only a relatively small force applied to the end of the operating lever, reducing the construction difficulty for the operator and improving construction efficiency.

[0008] In one optional embodiment, the mounting body includes a support body and a bracket, the mounting body being mounted on the ground; the bracket is vertically arranged and mounted on the support body; the take-up and release rollers are rotatably mounted on the bracket.

[0009] Beneficial effects: By vertically arranging the bracket on the support body, vertical support can be provided for the take-up and untake-up rollers, ensuring the stability of the copper busbars during take-up and untake-up, and avoiding the risk of deformation or breakage of the copper busbars due to structural instability. At the same time, during the rotation operation of the take-up and untake-up rollers, operators do not need to additionally straighten the bracket, reducing the degree of manual intervention in the copper busbar take-up and untake-up process, thereby reducing safety hazards caused by manual intervention.

[0010] In one optional embodiment, a pair of oppositely arranged sidewalls of the bracket are provided with horizontally extending mounting through holes; the copper busbar take-up and untake-down fixture further includes a support rod, which passes through the mounting through holes; wherein the take-up and untake-down roller is rotatably fitted onto the support rod, and the axis of the take-up and untake-down roller is collinear with the central axis of the support rod.

[0011] Beneficial effects: By aligning the axis of the take-up and release rollers with the central axis of the support rod, eccentricity is prevented during rotation. This provides the support rod with a precise and stable center of rotation for the take-up and release rollers, avoiding frictional losses caused by axis misalignment and extending the service life of key components such as the support rod and take-up and release rollers.

[0012] In one alternative embodiment, the support rod is provided with a connecting handle and a first fixing section along its length. The handle is located on one side of the mounting through hole and is configured to rotate under the action of an external force. One end of the first fixing section along its length is connected to the handle, and the other end is located on the other side of the mounting through hole. The first fixing section is configured to install a locking element.

[0013] Beneficial effects: The locking element applies a reliable axial constraint force at the end of the first fixed section of the support rod, which, in conjunction with the limiting action of the lever on the other side, firmly fixes the support rod, ensuring that there is no axial movement of the support rod when the take-up and untake-off rollers rotate. This maintains precise coaxial rotation, avoids increased frictional resistance due to slippage, and ensures the stable performance of the lever's labor-saving effect. Simultaneously, it reduces the risk of the support rod accidentally slipping out of the mounting hole due to vibration or force during operation, significantly improving operational safety and avoiding potential personal injury, equipment damage, and resulting delays. Furthermore, the locked support rod forms a rigid connection with the side wall of the bracket, increasing the rigidity of the entire take-up and untake-off roller support system, enabling it to better withstand the torque generated by the lever's leverage and the load on the copper busbar.

[0014] In one optional embodiment, the support rod is further provided with a rotating engagement section, which is connected to the first fixed section along the length of the support rod. The rotating engagement section is located on the side of the first fixed section away from the handle. The take-up and release rollers are provided with a rotating sleeve, which is rotatably mounted on the rotating engagement section.

[0015] Beneficial effects: By using a rotating sleeve to rotate and install on the rotating mating section of the support rod, a rotating friction pair is formed. Compared with the traditional rigid fixing method, the contact area can be reduced, thereby reducing frictional resistance. This allows the take-up and release rollers to operate efficiently under a smaller external force, making the copper busbar take-up and release movements more stable and avoiding copper busbar breakage or deformation caused by jamming.

[0016] In one alternative embodiment, the support rod is further provided with a second fixing section, which is connected to the rotating engagement section. The second fixing section is located on the side of the rotating engagement section opposite to the first fixing section, and the second fixing section is configured to install a locking element.

[0017] Beneficial effects: By using another locking element to fix it in the second fixed section, after the rotating sleeve is installed in the rotating mating section, the two locking elements are respectively installed in the first fixed section and the second fixed section of the support rod, forming a two-way limiting structure. The axial preload is applied to the rotating sleeve from both ends, which can limit the axial movement of the rotating sleeve and prevent the rotating sleeve from shifting or falling off along the axial direction when rotating.

[0018] In one alternative embodiment, the take-up and untake-down rollers further include a drum, which is coaxially fitted onto the outside of the rotating sleeve; the operating lever is mounted on the outside of the drum.

[0019] Beneficial effects: By adding a drum, the drum and the rotating sleeve can each independently perform different functions. That is, the drum is responsible for winding / supporting the copper busbar, and the rotating sleeve is responsible for rotational support and limiting, so that the rotational movement of the rotating sleeve and the winding action of the drum will not interfere with each other.

[0020] In one optional embodiment, the copper busbar winding and unwinding fixture further includes a connector and a limiting member. The connector is mounted to the support body; the limiting member is mounted to the connector and is configured to constrain the axial movement of the copper busbar during winding.

[0021] Beneficial effects: The limiting component is installed on the support body through the connector and applies axial constraint force to it when the copper busbar is wound, preventing the copper busbar from axial displacement due to external force or vibration during the winding and unwinding process.

[0022] In one optional embodiment, the operating lever and the connecting member are axially spaced along the axis of the take-up and unload rollers; the connecting member is provided with a rotating hole; the limiting member is provided with a rotating section, a transition section and a limiting section connected in sequence, the rotating section is rotatably inserted into the rotating hole, one end of the transition section is connected to the rotating section and the other end extends upwards towards the take-up and unload rollers, the limiting section is installed at the end of the transition section away from the rotating section, the limiting section is located on the side of the operating lever axially away from the connecting member along the axis of the take-up and unload rollers, and the end of the limiting section away from the transition section extends towards the ground, the limiting section rotates around the rotating section under the action of external force, the limiting section has a first state of gradually approaching the rotating hole to limit the axial movement of the copper busbar, and a second state of gradually moving away from the rotating hole to avoid loading and unloading the copper busbar.

[0023] Beneficial effects: By setting a rotating section that is inserted into the rotating hole, and by setting a transition section and a limiting section in sequence, the construction personnel can apply external force to the limiting section to drive it to rotate around the rotating section, smoothly rotate from the second state to the first state, and gradually approach the end face of the copper busbar, so that the limiting section can finally reliably abut against the end face of the copper busbar, forming a physical barrier and restricting the copper busbar from moving axially.

[0024] In one alternative embodiment, the operating levers are provided in a plurality of positions, and the plurality of operating levers are arranged circumferentially around the axis of the take-up and release rollers.

[0025] Beneficial effects: By setting multiple operating levers, when the construction worker pushes the current operating lever to a position where it is inconvenient to continue applying force, the other operating levers can still maintain an effective force application angle, forming a multi-point alternating drive mode, ensuring the continuity and stability of the take-up and release roller rotation process.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0044] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0045] According to an embodiment of this utility model, the provided copper busbar take-up and put-down fixture, such as... Figure 1 As shown, it includes a mounting body 1, a take-up and release roller 2, and an operating lever 3.

[0046] Mounting body 1 is used for fixed installation on the ground; take-up and release roller 2 is rotatably mounted on mounting body 1, and the axis of take-up and release roller 2 is parallel to the ground; one end of operating lever 3 along its length is mounted on the outer peripheral wall of take-up and release roller 2, and the other end extends radially away from take-up and release roller 2; wherein, external force is applied to operating lever 3 to drive take-up and release roller 2 to rotate around its axis, thereby realizing rapid take-up or release of copper busbar.

[0047] This setup, with a fixed mounting body 1 and a rotatable take-up / unwinding roller 2 mounted on the mounting body 1, allows the operator to rotate the take-up / unwinding roller 2 by driving the operating lever 3, thus achieving continuous and smooth winding or unwinding of the copper busbar. This replaces the traditional manual traction, winding, or unwinding method, allowing the operator to drive the take-up / unwinding roller 2 with only a relatively small force applied to the end of the operating lever 3, reducing the difficulty of operation and improving efficiency.

[0048] It can be explained that after the take-up and release rollers 2 are installed on the mounting body 1, they are arranged at intervals in the height direction from the mounting body 1.

[0049] That is, the take-up and release roller 2 is raised to a certain height off the ground, so that the construction workers can rotate the operating lever 3 in a more natural and comfortable standing posture, avoiding the fatigue caused by bending over or squatting for a long time.

[0050] In one embodiment, such as Figures 1 to 3 As shown, the mounting body 1 includes a support body 11 and a bracket 12. The support body 11 is mounted on the ground; the bracket 12 is arranged vertically and is mounted on the support body 11; the take-up and release roller 2 is rotatably mounted on the bracket 12.

[0051] This configuration, by vertically arranging the bracket 12 on the support body 11, can provide vertical support for the take-up and take-down rollers 2, ensuring that the copper busbar remains stable during take-up and take-down, and avoiding the risk of deformation or breakage of the copper busbar due to structural instability.

[0052] Meanwhile, during the rotation operation of the take-up and release roller 2, the operator does not need to additionally straighten the support 12, reducing the degree of manual intervention in the take-up and release of copper busbars, thereby reducing safety hazards caused by manual intervention.

[0053] It can be noted that the supporting body 11 is arranged in a cross shape.

[0054] This configuration creates multi-point support and symmetrical force distribution, effectively dispersing external forces on the support body 11 in the horizontal and vertical directions, reducing local stress concentration, and thus improving overall overturning resistance and seismic performance. Simultaneously, it expands the effective grounding contact area, forming a wider range of physical contact with the substrate (such as the ground or concrete base), reducing pressure per unit area and minimizing settlement risk.

[0055] Furthermore, the bracket 12 is installed at the cross-shaped intersection of the support body 11.

[0056] Preferably, the support body 11 is a cross-shaped groove.

[0057] Preferably, the support body 11 is provided with connection holes for anchor bolts to be installed on the ground.

[0058] Furthermore, an internally threaded mounting protrusion is provided above the connection hole. During installation, the anchor bolt is screwed into the mounting protrusion by rotation, and then screwed into the ground after passing through the connection hole, which increases the stability of the equipment and ensures its stability when carrying out line laying operations on uneven ground.

[0059] It can be noted that the end of the anchor bolt used for mounting to the ground has a nail-like structure.

[0060] In one embodiment, such as Figures 1 to 3 , Figure 5 and Figure 6 As shown, a pair of oppositely arranged sidewalls of the bracket 12 are provided with mounting through holes extending in the horizontal direction; the copper busbar take-up and untake-down fixture also includes a support rod 4, which passes through the mounting through holes; wherein, the take-up and untake-down roller 2 is rotatably fitted onto the support rod 4, and the axis of the take-up and untake-down roller 2 is collinear with the central axis of the support rod 4.

[0061] This configuration ensures that there is no eccentric movement during rotation by aligning the axis of the take-up and release roller 2 with the central axis of the support rod 4. This provides the support rod 4 with a precise and stable rotation center for the take-up and release roller 2, avoiding frictional losses caused by axis misalignment and extending the service life of key components such as the support rod 4 and the take-up and release roller 2.

[0062] In one embodiment, such as Figures 1 to 3 , Figure 5 and Figure 6As shown, the support rod 4 is provided with a connecting handle 41 and a first fixing section 42 along its length. The handle 41 is located on one side of the mounting through hole and is configured to rotate under the action of external force. One end of the first fixing section 42 along its length is connected to the handle 41, and the other end is located on the other side of the mounting through hole. The first fixing section 42 is configured to install the locking member 7.

[0063] With this configuration, the locking element 7 (such as tightening the nut, inserting the pin, or snapping the snap ring) applies a reliable axial constraint force at the end of the first fixed section 42 of the support rod 4. This, combined with the limiting action of the actuator 41 on the other side, firmly fixes the support rod 4, ensuring that the support rod 4 does not move axially when the take-up and take-off roller 2 rotates. This maintains precise coaxial rotation, avoids increased frictional resistance due to movement, and ensures the stable performance of the labor-saving effect of the operating lever 3.

[0064] At the same time, it reduces the risk of the support rod 4 accidentally slipping out of the mounting hole due to vibration or force during operation, greatly improving operational safety and avoiding potential personal injury and equipment damage accidents and the resulting delays.

[0065] In addition, the locked support rod 4 forms a rigid connection with the side wall of the bracket 12, which improves the rigidity of the entire take-up and take-down roller 2 support system, enabling it to better withstand the torque generated by the lever force of the operating rod 3 and the load of the copper busbar.

[0066] It can be noted that a gasket 8 is installed between the means 41 and the side wall where the opening of the mounting through hole is located.

[0067] In one embodiment, such as Figures 1 to 3 , Figure 5 and Figure 6 As shown, the support rod 4 is also provided with a rotating engagement section 43. Along the length direction of the support rod 4, the rotating engagement section 43 is connected to the first fixed section 42. The rotating engagement section 43 is located on the side of the first fixed section 42 away from the handle 41. The take-up and take-down roller 2 is provided with a rotating sleeve 21, which is rotatably installed on the rotating engagement section 43.

[0068] This configuration, by using the rotating sleeve 21 to rotate and install the rotating mating section 43 of the support rod 4 to form a rotating friction pair, can reduce the contact area compared to the traditional rigid fixing method, thereby reducing frictional resistance. This allows the take-up and release roller 2 to operate efficiently under a smaller external force, making the copper busbar take-up and release action more stable and avoiding copper busbar breakage or deformation caused by jamming.

[0069] In one embodiment, such as Figures 1 to 3 , Figure 5 and Figure 6As shown, the support rod 4 is also provided with a second fixed section 44, which is connected to the rotating engagement section 43. The second fixed section 44 is located on the side of the rotating engagement section 43 away from the first fixed section 42, and the second fixed section 44 is configured to install the locking element 7.

[0070] With this configuration, by using another locking element 7 to fix it in the second fixed section 44, after the rotating sleeve 21 is installed in the rotating mating section 43, the two locking elements 7 are respectively installed in the first fixed section 42 and the second fixed section 44 of the support rod 4, forming a two-way limiting structure. An axial preload is applied to the rotating sleeve 21 from both ends, which can limit the axial movement of the rotating sleeve 21 and prevent the rotating sleeve 21 from shifting or falling off along the axial direction when rotating.

[0071] Preferably, the locking element 7 installed at the first fixed section 42 and the locking element 7 installed at the second fixed section 44 are both selected as lock nuts.

[0072] Furthermore, at least one bearing is provided radially between the rotating sleeve 21 and the rotating mating section 43.

[0073] In one embodiment, such as Figure 1 As shown, the take-up and untake-down roller 2 also includes a drum 22, which is coaxially mounted on the outside of the rotating sleeve 21; the operating lever 3 is installed on the outside of the drum 22.

[0074] With this configuration, by adding a spool 22, the spool 22 and the rotating sleeve 21 can each independently perform different functions. That is, the spool 22 is responsible for winding and supporting the copper busbar, while the rotating sleeve 21 is responsible for rotational support and limiting, so that the rotational movement of the rotating sleeve 21 and the winding action of the spool 22 will not interfere with each other.

[0075] Furthermore, a connecting post 9 is provided between the rotating sleeve 21 and the drum 22 in the radial direction.

[0076] Preferably, to reduce costs, the connecting column 9 is made of steel pipes available on the construction site.

[0077] Furthermore, multiple connecting columns 9 are provided, and the multiple connecting columns 9 are arranged in a circumferential array around the axis of the take-up and take-off roller 2.

[0078] In one embodiment, such as Figures 1 to 4 As shown, the copper busbar winding and unwinding fixture also includes a connector 5 and a limiting member 6. The connector 5 is installed on the support body 11; the limiting member 6 is installed on the connector 5, and the limiting member 6 is configured to constrain the axial movement of the copper busbar during winding.

[0079] With this configuration, the limiting member 6 is installed on the support body 11 through the connecting member 5, and applies axial constraint force to it when the copper busbar is wound, preventing the copper busbar from axially displacing due to external force or vibration during the winding and unwinding process.

[0080] It can be noted that, in order to reduce costs, connector 5 is preferably a hollow steel pipe.

[0081] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the operating lever 3 and the connecting piece 5 are axially spaced along the axis of the take-up and unload roller 2; the connecting piece 5 is provided with a rotating hole 51; the limiting piece 6 is provided with a rotating section 61, a transition section 62 and a limiting section 63 connected in sequence. The rotating section 61 is rotatably inserted into the rotating hole 51. One end of the transition section 62 is connected to the rotating section 61, and the other end extends upward toward the take-up and unload roller 2. The limiting section 63 is installed at the end of the transition section 62 away from the rotating section 61. The limiting section 63 is located on the side of the operating lever 3 axially away from the connecting piece 5 along the axis of the take-up and unload roller 2, and the end of the limiting section 63 away from the transition section 62 extends toward the ground. The limiting section 63 rotates around the rotating section 61 under the action of external force. The limiting section 63 has a first state of gradually approaching the rotating hole 51 to limit the axial movement of the copper busbar, and a second state of gradually moving away from the rotating hole 51 to avoid loading and unloading the copper busbar.

[0082] When the limiting section 63 is in the first state, the limiting section 63 is configured to axially abut one end of the copper busbar under the action of external force; thus restricting the axial movement of the copper busbar wound on the outside of the take-up and unwind roller 2.

[0083] With this configuration, by setting the rotating section 61 to be rotatably inserted into the rotating hole 51, and by sequentially setting the transition section 62 and the limiting section 63, the construction personnel can apply external force to the limiting section 63 to drive it to rotate around the rotating section 61, smoothly rotating from the second state (avoidance position) to the first state (limiting position), and gradually approaching the end face of the copper busbar, so that the limiting section 63 can finally reliably abut against the end face of the copper busbar, forming a physical barrier and restricting the copper busbar from moving axially.

[0084] In one embodiment, such as Figure 1 As shown, there are multiple operating levers 3, which are arranged circumferentially around the axis of the take-up and take-off rollers 2.

[0085] With this configuration, by setting up multiple operating levers 3, when the construction worker pushes the current operating lever 3 to a position where it is inconvenient to continue applying force (such as approaching the support 12 or being restricted by space), the other operating levers 3 can still maintain an effective force application angle, forming a multi-point alternating drive mode to ensure the continuity and stability of the rotation process of the take-up and release rollers 2.

[0086] At the same time, the operating lever 3 and the limiting section 63 apply constraint forces from both sides of the copper busbar to form a bidirectional clamping.

[0087] In addition, multiple operating levers 3 are evenly distributed circumferentially, dispersing the axial constraint force of the copper busbar to multiple contact points rather than concentrating it on a single point, making the surface of the copper busbar more uniformly stressed and avoiding local indentation, deformation or breakage caused by single-point limiting.

[0088] In the copper busbar winding and unwinding fixture described in the above embodiment, during installation, the bracket 12 is installed on the support body 11, and the support rod 4 is inserted through the mounting hole. Then, a locking piece 7 is installed on the first fixed section 42 and locked to fix the support rod 4 to the support body 11. Then, the connecting column 9 is used to complete the coaxial installation of the rotating sleeve 21 and the drum 22. Then, the rotating sleeve 21 is installed on the rotating mating section 43, and another locking piece 7 is installed on the second fixed section 44 until the two locking pieces 7 restrict the rotating sleeve 21 from moving axially. Then, the rotating section 61 of the limiting piece 6 is inserted into the rotating hole 51. Then, the copper busbar is wound around the copper busbar winding and unwinding fixture and moved to the construction site. Then, the support body 11 is fixed above the ground with anchor bolts, and then the copper busbar is unwound.

[0089] During this process, the operator continuously rotates the limit segment 63, ensuring that the limit segment 63 remains in contact with one end of the copper busbar.

[0090] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
