Description

Technical Field

[0001] This invention relates to the field of motor track technology, and in particular to a tracked motor track and its deployment and retraction method. Background Technology

[0002] A linear motor is a power device that directly converts electrical energy into linear motion mechanical energy. Because it eliminates the need for intermediate transmission mechanisms and boasts high transmission efficiency, linear motors have been widely used in industrial fields such as rail transportation, industrial control, and CNC machine tools. With the increasing application scenarios of linear motors across various fields, and the growing demand for high-speed, long-stroke operating conditions, the need for ultra-long linear motors is increasing daily; however, ultra-long motors are difficult to transport.

[0003] In existing technologies, multiple short linear motors are typically spliced ​​together to achieve higher linear motion speeds. However, connecting multiple linear motors requires pre-setting motor tracks for operation to ensure accurate connection. These tracks need to be pre-set, requiring tooling installation in industrial plants and pre-setting trenches or welding anchor bolts on outdoor surfaces. This process is time-consuming and labor-intensive, making it unsuitable for time-sensitive applications requiring rapid operation.

[0004] Furthermore, the transfer of linear motors is generally carried out using a crane, which requires considerable preparation and external conditions including a crane, operators, and a supervisor. There are also certain safety hazards during the lifting process. If on-site equipment is insufficient, the transfer of linear motors will be difficult.

[0005] After the linear motor is connected, the power cabinet and the linear motor are connected by a cable. For long-distance cable connections, the cable is heavy and difficult to drag. Long-distance connections are time-consuming and laborious. In addition, the cables are messy during the connection process, making operation inconvenient and posing safety hazards.

[0006] Currently, the commonly used linear motor track laying, linear motor transfer, and cable laying are three separate systems that are completed sequentially. This process is labor-intensive, inefficient, and cannot meet the needs of time-sensitive and rapid operations. Summary of the Invention

[0007] Based on the above analysis, the present invention aims to provide a tracked motor track and its deployment and retraction method to solve the problems of cumbersome, time-consuming and labor-intensive linear motor track laying operations and difficult linear motor transportation in the prior art.

[0008] The objective of this invention is mainly achieved through the following technical solutions:

[0009] A method for deploying and retracting a tracked motor track, comprising the following steps:

[0010] Step 1: Unfold the motor track;

[0011] Step 2: Transport the linear motor;

[0012] Step 3: Retract the motor track.

[0013] Further, in step 1, the cable is installed on the clamp.

[0014] Furthermore, in step 1, a rotary motor is driven so that the drive sprocket rotates synchronously with the rotary motor.

[0015] Furthermore, in step 1, the inner track moves under the drive of the drive sprocket.

[0016] Furthermore, in step 1, the outer track is deployed.

[0017] Furthermore, in step 2, the linear motor is placed on the outer track.

[0018] Further, in step 2, the linear motor is connected to the cable.

[0019] Furthermore, in step 3, the rotary motor is driven in reverse so that the drive sprocket rotates synchronously with the rotary motor.

[0020] Furthermore, in step 3, the convex circle on the outer track is inserted into the groove.

[0021] Furthermore, a tracked motor track, used for a method of deploying and retracting a tracked motor track, is characterized by comprising a drive assembly, an inner track, and an outer track; the outer track can be stacked on the outer wall of the inner track, and the drive assembly is used to drive the outer track so that it can be deployed or stacked on the outer wall of the inner track, thereby laying or retracting the motor track; the motor track is used to transport a linear motor.

[0022] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0023] (1) The method for retracting and extending the tracked motor track of the present invention involves driving the inner track with a drive assembly, thereby causing the outer track, which is fixed to the upper end of the inner track, to be stacked on or unfolded from the outer wall of the inner track, thus realizing the retraction or laying of the motor track. This method changes the process of transporting multiple short linear motors, and achieves the pre-laying of the linear motor track by unfolding the outer track, which greatly improves the efficiency and accuracy of track laying, while reducing the expenditure of manpower and material resources, making it convenient, fast, and efficient.

[0024] (2) The present invention provides a connecting plate at the fixed end of the outer track and the side end face of the inner track. In order to make the outer track and the inner track fixedly connected, the connecting plate is sleeved on the pin of the fixed end of the outer track and the inner track, so that the two cannot be displaced relative to each other.

[0025] (3) Each single chain link of the present invention is provided with a convex circle and a groove. When the track is curled, the convex circle at the top of the single chain link of the outer track is inserted into the groove at the bottom of the single chain link of the inner track, so that the stacked tracks can be interlocked and avoid misalignment.

[0026] (4) The single-link chain in this invention also includes a transfer component for transferring the linear motor. The through hole on the single-link chain is clearance-fitted with the connecting pin, allowing the connecting pin to rotate freely within the through hole of the single-link chain. This transforms the sliding friction of the traditional linear motor into rolling friction, significantly reducing friction and saving manpower and resources.

[0027] (5) In this invention, the single-link chain includes a transfer assembly for transferring the linear motor. The through hole on the single-link chain is clearance-fitted with the connecting pin, ensuring that the connecting pin can rotate freely within the through hole of the single-link chain. The linear motor is placed on the nut, and the linear motor and the nut are rolled together to achieve the transfer of the linear motor.

[0028] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or may be learned by practicing the invention.

[0041] The following detailed description of a tracked motor track and its deployment and retraction method, with reference to specific embodiments, is provided. These embodiments are for comparative and illustrative purposes only, and the present invention is not limited to these embodiments.

[0042] Example 1

[0043] A method for deploying and retracting a tracked motor track, such as... Figure 9 As shown, the specific steps include:

[0044] Step 1: As Figures 1-2 As shown, unfold the motor track.

[0045] Step 11: As Figures 6-8 As shown, install cable 6.

[0046] Open the clamp 7 fixed on the single chain 41 and place the cable 6 inside the clamp 4 so that the clamp 7 can fix the cable 6 to the outer track 4.

[0047] Step 11: Drive the rotary motor 1.

[0048] Drive the rotary motor 1 to rotate in the same rolling direction as the outer track 4, and the drive sprocket 2 moves synchronously and in the same direction as the rotary motor 1.

[0049] Step 12: The inner track 3 rotates under the drive of the drive sprocket 2.

[0050] The drive sprocket 2 drives the inner track 3, which meshes with it, to move synchronously and in the same direction. The tension wheel 5 is passively driven by the inner track 3 to move synchronously and in the same direction with the drive sprocket 2, so that the closed inner track 3 rotates and translates continuously in the same direction under the drive of the drive sprocket 2.

[0051] With the combined support of the drive sprocket 2 and the tensioning wheel 5, the inner track 3 can form a track with a fixed shape, allowing the outer track 4 to wrap around the inner track 3 with a fixed shape. Thus, the length of the track can be calculated by the number of turns of the outer track 4 on the outer wall of the inner track 3, which is used to accurately determine the length of the track.

[0052] Step 13: Deploy the outer track 4.

[0053] The inner track 3 drives the outer track 4, which is fixed on the inner track 3, to move synchronously, so that the outer track 4 separates from the inner track 3 segment by segment from the outside to the inside, and the track unfolds.

[0054] The deployment method of the tracked motor track abandons the traditional method of splicing multiple short linear motors into a single track. It changes the operation process of multiple linear motors and eliminates the need for additional pre-installation steps. The linear motor track is pre-laid directly by unfolding the free end of the outer track, which greatly improves the efficiency and accuracy of track laying. At the same time, it reduces the expenditure of manpower and material resources, making the laying of the motor track convenient, fast, and efficient, while also facilitating transportation, movement, and storage.

[0055] Step 2: As Figures 6-7 As shown, the transport linear motor 10.

[0056] Step 21: Place the linear motor 10 on the outer track 4.

[0057] The linear motor 10 is placed on the nut 43 of the single-link chain 41, wherein the width L of the linear motor 10 needs to be between the spacing N of the inner edge of the nut 43 and the spacing M of the inner side of the single-link chain 41.

[0058] The above relationship is to ensure that the bottom of the linear motor 10 can contact the nut 43, so that the linear motor 10 can rotate through the nut 43. If L is less than N, the linear motor 10 will not contact the nut 43 and will fall directly onto the cable in the middle of the single-link chain 41. The linear motor 10 will not be able to move, and the motor may damage the cable. If L is greater than M, the linear motor 10 will fall onto the edge of the single-link chain 41 and will exceed the range of the nut 43, making it impossible for the linear motor 10 to roll on the nut 43.

[0059] Step 22: As Figure 6 As shown, an external power source is used to transport the linear motor 10.

[0060] An external pulling device or manual force is applied to the linear motor 10 placed on the nut 43, causing the linear motor 10 to roll and rub against the nut 43. The nut 43 drives the connecting pin 42, which is threaded to it, to rotate synchronously, so that the connecting pin 42 rotates in the through hole of the single chain 41.

[0061] In this invention, the sliding friction of the linear motor 10 is changed to rolling friction, which greatly reduces the frictional force and saves time and effort.

[0062] Step 23: Connect cable 6 to linear motor 10.

[0063] After the linear motor 10 has been completely transported to the designated position by the outer track 4, the cable 6 laid inside the outer track 4 is connected to the cable connector on the linear motor 10 to realize the connection of the cable.

[0064] Step 3: Retract the linear motor 10.

[0065] After using the linear motor 10, disconnect the cable 6 from the linear motor 10 and remove the linear motor 10 from the motor track in preparation for retracting the motor track later.

[0066] Step 4: Retract the motor track.

[0067] Step 41: Drive the rotary motor 1.

[0068] Drive the rotary motor 1 to rotate in the opposite direction to the outer track 4. The drive sprocket 2 moves synchronously with the rotary motor 1 (i.e., drives the rotary motor 1 to rotate in the opposite direction to that in step 11).

[0069] Step 42: The inner track 3 rotates under the drive of the drive sprocket 2.

[0070] The drive sprocket 2 drives the inner track 3, which meshes with it, to move synchronously. The tension wheel 5 is passively driven by the inner track 3 and moves synchronously with the drive sprocket 2, so that the closed inner track 3 performs continuous rotational and translational motion under the drive of the drive sprocket 2.

[0071] Step 43: As Figures 3-5 As shown, the convex circle 44 on the outer track 4 is inserted into the groove 45.

[0072] The outer track 4 is rolled up, and the convex circle 44 at the top of the single chain 41 of the outer track 4 is inserted into the groove at the bottom of the single chain 41 of the inner track 4.

[0073] The inner and outer tracks are directly engaged through the interlocking between the convex circle 44 and the groove 45, so that the stacked tracks can interlock with each other and avoid misalignment.

[0074] Step 44: Retract the outer track 4.

[0075] The inner track 3 drives the outer track 4, which is fixed on the inner track 3, to move synchronously. As a result, the fixed end of the outer track 4 is rolled up sequentially from the inside to the outside onto the inner track 3 under the drive of the inner track 3, so that the track is retracted.

[0076] Step 45: The cable 6 and the outer track 4 are bent and rolled up simultaneously.

[0077] The cable 6 is bent and rolled up synchronously with the outer track 4, driven by the outer track 4. The radius of the arc segment of the inner track 3 is larger than the bending radius of the cable 6 to ensure that the cable will not be damaged after multiple bends. The motor track is then retracted and stored for future use.

[0078] Example 2

[0079] A specific embodiment of the present invention, such as Figures 1-2 As shown, a tracked motor track is disclosed. The tracked motor track is used to realize the tracked motor track deployment and retraction method of Embodiment 1. It includes a drive assembly, an inner track 3 and an outer track 4. The outer track 4 can be stacked on the outer wall of the inner track 3. The drive assembly is used to drive the outer track 4 so that it can be deployed or stacked on the outer wall of the inner track 3 to realize the laying or retraction of the motor track.

[0080] Furthermore, the inner track 3 is a closed-loop track structure, one end of the outer track 4 is a fixed end, which is fixedly connected to the inner track 3, and the other end of the outer track 4 is a free end. The free end can be stacked and rolled outward to the outer wall of the inner track 3 to retract the track, or the free end can be unfolded from the inner track to lay the track.

[0081] Furthermore, the drive assembly includes a rotary motor 1, a drive sprocket 2, and a tensioning wheel 5. The rotary motor 1 is coaxially arranged with the drive sprocket 2 and is located inside the drive sprocket 2. The rotary motor 1 is used to drive the drive sprocket 2 to rotate in two directions (clockwise rotation and counterclockwise rotation).

[0082] Furthermore, the drive sprocket 2 and tension wheel 5 mesh with the inner track 3, and the drive sprocket 2 and tension wheel 5 are spaced apart. Under the joint support of the drive sprocket 2 and tension wheel 5, the inner track 3 of the closed-loop structure can be fully stretched and tensioned.

[0083] It is worth noting that the drive sprocket 2 and the tensioning wheel 5 are arranged parallel to each other in the horizontal direction, so that when the outer track 4 is wrapped and stacked on the inner track 3, the track space in the vertical direction can be evenly distributed to the horizontal direction, saving the track space in the vertical direction and facilitating the overall transportation and storage of the track.

[0084] Specifically, on one hand, when the rotation direction of the rotary motor 1 is opposite to the winding direction of the outer track 4 on the inner track 3, the drive sprocket 2 moves synchronously and in the same direction as the rotary motor 1. The drive sprocket 2 drives the inner track 3, which meshes with it, to move synchronously and in the same direction. The tension wheel 5 is passively driven by the inner track 3 and moves synchronously and in the same direction as the drive sprocket 2, thereby driving the fixed end of the outer track 4, which is fixed on the inner track 3, to move synchronously. Thus, the outer track 4, driven by the fixed end, can be wound section by section onto the inner track 3, causing the track to retract.

[0085] On the other hand, when the rotation direction of the rotary motor 1 is in the same direction as the winding direction of the outer track 4 on the inner track 3, the drive sprocket 2 moves synchronously and in the same direction as the rotary motor 1. The drive sprocket 2 drives the inner track 3, which meshes with it, to move synchronously and in the same direction. The tension wheel 5 is passively driven by the inner track 3 and moves synchronously and in the same direction as the drive sprocket 2, thereby driving the fixed end of the outer track 4, which is fixed on the inner track 3, to move synchronously. Thus, the outer track 4, driven by the fixed end, separates from the inner track 3 section by section from the outside to the inside, causing the track to unfold.

[0086] To enable a fixed connection or relative stillness between the outer track 4 and the inner track 3, a connecting plate 7 is also included, such as... Figure 3 As shown, the fixed end of the outer track 4 is fixedly connected to the inner track 3 by a connecting plate 7.

[0087] Specifically, the connecting plate 7 is disposed on the fixed end of the outer track 4 and the side end face of the inner track 3. The connecting plate 7 is sleeved on the pin of the fixed end of the outer track 4 and the inner track 3, so that there is no relative displacement between the two.

[0088] In one embodiment, the outer track 4, inner track 3, and connecting plate 7 are detachable, allowing the fixed end of the outer track 4 to be fixedly connected to different sections of the inner track 3 as needed, enabling the outer track 4 to be fixed at any position on the inner track 3. Furthermore, this detachability between the outer track 4 and the inner track 3 allows for separation of the outer track 4 and inner track 3 during track maintenance via the connecting plate 7, enabling separate maintenance and increasing efficiency while reducing costs.

[0089] In another embodiment, the fixed end of the outer track 4 is hinged to the inner track 3 via a hinge shaft of the same width as the track, so that the outer track 4 and the inner track 3 are relatively stationary. When the inner track 3 rotates, the outer track 4 can be wound clockwise or counterclockwise (i.e., wound in both directions) on the inner track 3, so that the outer track 4 is not restricted by the rotation direction of the inner track 3, and its application range is wider.

[0090] Furthermore, such as Figures 4-5As shown, the outer track 4 includes multiple single-link chains 41, which are arranged in parallel and hinged to each other.

[0091] Furthermore, each single-link chain 41 includes a convex circle 44 and a groove 45. The convex circle 44 is disposed on the upper surface of the single-link chain 41, and the groove is disposed on the lower surface of the single-link chain 41. During the winding process of the track, the convex circle 44 at the top of the single-link chain 41 of the outer track layer engages with the groove at the bottom of the single-link chain 41 of the inner track layer. The inner and outer tracks are directly engaged by the engagement between the convex circle 44 and the groove 45, so that the stacked tracks can be interlocked and misalignment is avoided.

[0092] Furthermore, such as Figures 6-7 As shown, each single chain link 41 also includes a transfer component. Each single chain link 41 includes two transfer components, which are symmetrically arranged at both ends of the single chain link 41 for transferring the linear motor 10.

[0093] Furthermore, the transfer assembly includes a connecting pin 42 and a nut 43. Both ends of the single-link chain 41 are provided with through holes, through which the connecting pin 42 passes. At the same time, both ends of the connecting pin 42 are spirally connected to the nut.

[0094] Specifically, the through hole on the single-link chain 41 is clearance-fitted with the connecting pin 42, ensuring that the connecting pin 42 can rotate freely within the through hole of the single-link chain 41. The nut 43 is threadedly fastened to the end of the connecting pin 42, thereby limiting the position of the connecting pin 42 and ensuring that the connecting pin 42 will not slip out of the through hole of the single-link chain 41.

[0095] It is worth noting that the nut 43 in this embodiment is a round nut in order to ensure that the linear motor 10 can roll on the nut 43.

[0096] When the linear motor 10 is transferred by the transfer assembly, the linear motor 10 is placed on the nut 43, and the linear motor 10 is in a rolling connection with the nut 43 to realize the transfer of the linear motor 10.

[0097] It is worth noting that, such as Figure 6 As shown, the inner spacing of the single chain link 41 is M, the spacing of the inner edges of the nut 43 is N, and the width of the linear motor 10 is L. The width L of the linear motor 10 must be between the spacing N of the inner edges of the nut 43 and the spacing M of the inner edges of the single chain link 41, i.e., it must satisfy the following relationship: N < L < M.

[0098] Specifically, N < L < M is to ensure that the bottom of the linear motor 10 can contact the nut 43, allowing the linear motor 10 to rotate through the nut 43. If L is less than N, the linear motor 10 will not contact the nut 43 and will fall directly onto the cable in the middle of the single-link chain 41. The linear motor 10 will not be able to move, and the motor may damage the cable. If L is greater than M, the linear motor 10 will fall onto the edge of the single-link chain 41, and the linear motor 10 will exceed the range of the nut 43, making it impossible for the linear motor 10 to roll on the nut 43. Therefore, the relationship among the three is: N < L < M.

[0099] Specifically, the linear motor 10 rests on the nuts 43 on both sides. When the linear motor 10 moves, the nuts 43 drive the connecting pin 42 to rotate in the through hole of the single chain 41. Under the drive of the external traction mechanism, the horizontal movement of the linear motor 10 is converted into the rotation of the connecting pin 42, thus realizing the rapid transfer and transportation of the linear motor 10.

[0100] The connecting pin 42 acts like a bearing, transforming the planar movement of the linear motor 10 into the rotation of the connecting pin 42, changing dragging into rolling, that is, changing sliding friction into rolling friction, which greatly reduces friction and saves time and effort.

[0101] Furthermore, such as Figure 8 As shown, it also includes a cable 6 and a clamp 7. The clamp 7 is fixedly welded to a single-section chain 41 and is used to hold the cable 6 in place. In use, the clamp 7 is pried open, and the cable 6 is placed inside the clamp 7 to prevent the cable 6 from falling off or getting tangled.

[0102] The radius of the arc segment of the inner track 3 is larger than the bending radius of the cable 6 to ensure that the cable will not be damaged after multiple bends.

[0103] Once all linear motors 10 have been moved to their designated positions, the cables 6 laid inside the outer track 4 are connected to the cable connectors on the linear motors 10, thus completing the cable connection. The starting position of the cables 6 on the track system 4 should be designed based on the completed deployment and docking status of the linear motors 10, the location of the on-site power cabinet, and the principles of proximity and ease of operation.

[0104] The tracked motor track provided by this invention enables simultaneous operation of three systems: linear motor track laying, rapid linear motor transfer, and cable laying. It has a high degree of integration and improves the efficiency of actual use.

[0105] Compared with existing technologies, the tracked motor track provided by this invention has a high degree of overall integration, and can simultaneously solve the problems of linear motor track laying, linear motor transfer, and cable laying; it has wide applicability and can be used for various linear motor transfers and cable laying, with no limitation on the laying distance. For operating conditions without pre-set tracks, multiple linear motor segments connecting, and tight preparation time, it can significantly improve the efficiency of linear motor layout, transfer, and cable connection.

[0106] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
