Description

Technical Field

[0001] This utility model relates to the field of rail transportation technology, and in particular to a traction drive device applied to suspended rails. Background Technology

[0002] To improve production efficiency, many production environments utilize track-based systems for transporting goods. Furthermore, to maximize space utilization, existing technologies often employ overhead cranes or similar equipment in factories (or other application scenarios) to perform transport operations using suspended transport methods. Typically, such equipment includes support column assemblies, track assemblies, and a transport device. The track assembly is mounted on the support column assembly, while the transport device is movably mounted on the track assembly to achieve the function of transporting goods.

[0003] However, in existing technologies, the traction equipment on overhead cranes and overhead rigs is often built into the device. If the traction equipment needs to be repaired, it must be completely removed before repairs can be carried out. This results in the entire device being unusable during the repair period, which affects the production and operation schedule and delays production efficiency. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, this utility model proposes a traction drive device for suspended tracks that is easy to replace, easy to operate, and can effectively realize driving and braking functions.

The first connection point of the first bearing mechanism is movably connected to the first connection point of the second bearing mechanism, and the second connection point of the first bearing mechanism is connected to the second connection point of the second bearing mechanism through the self-locking telescopic unit. By adjusting the extension and retraction state of the self-locking telescopic unit, the second bearing mechanism can drive the mobile drive unit to move closer to or away from the first bearing mechanism.

[0006] In the aforementioned traction drive device applied to suspended tracks, the first connection point of the first load-bearing mechanism is hinged to the first connection point of the second load-bearing mechanism.

[0007] The aforementioned traction drive device applied to suspended tracks, wherein the self-locking telescopic unit includes a motor mechanism, a self-locking screw mechanism, and a third bearing mechanism; the third bearing mechanism includes a traction frame component and a motor bearing component; The traction frame component is hinged to the second connection point of the first load-bearing mechanism, and the motor load-bearing component is hinged to the second connection point of the second load-bearing mechanism; The motor bearing component is connected to the motor mechanism, and the self-locking screw mechanism is connected to the output part of the motor mechanism and the traction frame component respectively.

[0008] The aforementioned traction drive device for suspended tracks, wherein the self-locking screw mechanism includes a screw and a nut; The traction frame component has a receiving cavity, the nut is located in the receiving cavity, and the nut is at least partially in contact with the inner wall of the receiving cavity, so that there is no relative rotation between the nut and the traction frame component; One end of the lead screw is connected to the output of the motor mechanism, and the other end of the lead screw extends through a through hole on the motor-adjacent end of the traction frame into the receiving cavity, so that the lead screw is threadedly connected to the nut.

[0009] The aforementioned traction drive device applied to suspended tracks includes a self-locking screw mechanism that further comprises an elastic component. The elastic component is sleeved on the screw and is located between the nut and the motor-adjacent end of the traction frame component.

[0010] In the aforementioned traction drive device applied to suspended tracks, a first limiting component is provided at one end of the lead screw extending into the receiving cavity.

[0011] In the aforementioned traction drive device applied to suspended tracks, a second limiting component is provided at one end of the lead screw located outside the traction frame component.

[0012] The aforementioned traction drive device applied to suspended tracks includes a first through hole coaxially arranged with the lead screw in the motor bearing component, and a second through hole perpendicular to the lead screw in the motor bearing component. A first bearing is provided in the first through hole, and the lead screw passes through the first bearing; The second bearing is provided in the second through hole, and the second connection point of the second bearing mechanism is hinged to the motor bearing member through the second bearing in the second through hole of the motor bearing member.

[0013] The aforementioned traction drive device applied to suspended tracks includes a fourth support mechanism in the bearing unit. The fourth support mechanism is connected to the second support mechanism and is used to support the first drive control component and the second drive control component. The first drive control component is connected to the mobile drive unit, and the second drive control component is connected to the self-locking telescopic unit.

[0014] The aforementioned traction drive device applied to suspended tracks includes a mobile drive unit comprising a drive mechanism and a drive wheel. The drive mechanism is connected to the second load-bearing mechanism, and the drive wheel is connected to the output component of the drive mechanism.

[0015] The aforementioned traction drive device for suspended tracks further includes a driven wheel unit in the drive module. The driven wheel unit includes several driven wheels disposed on the first bearing mechanism.

[0016] The aforementioned traction drive device for suspended tracks, wherein the traction module includes a traction rod; One end of the traction rod is hinged to the first bearing mechanism, and the other end of the traction rod is used for detachable connection with the device to be transported.

[0017] The beneficial effects of this utility model on the traction drive device applied to suspended tracks are as follows: The traction drive device applied to the suspended track includes a drive module and a traction module. The drive module is detachably connected to the external device to be transported through the traction module, so that when the traction drive device fails, it will not affect the normal use of the external device to be transported, thereby ensuring the overall operating efficiency of the carrying device. Meanwhile, the drive module includes a load-bearing unit, a moving drive unit, and a self-locking telescopic unit. The load-bearing unit includes a first load-bearing mechanism and a second load-bearing mechanism. The first connection point of the first load-bearing mechanism is movably connected to the first connection point of the second load-bearing mechanism, and the second connection point of the first load-bearing mechanism is connected to the second connection point of the second load-bearing mechanism through the self-locking telescopic unit. By adjusting the extension and retraction state of the self-locking telescopic unit, the second load-bearing mechanism drives the moving drive unit closer to or further away from the first load-bearing mechanism, thereby controlling whether the moving drive unit is in contact with the track. This satisfies the control of the driving module's driving and braking functions using the moving drive unit, while also ensuring the traction drive device is easy to disassemble. Furthermore, because the device uses a self-locking telescopic unit, it avoids relative displacement between the first load-bearing mechanism and the second load-bearing mechanism under the action of gravity, improving the reliability of the traction drive device during use.

[0018] This traction drive device is characterized by its ease of use, convenient disassembly, individual replacement capability, high reliability, and strong adaptability, effectively ensuring the operational efficiency of equipment transporting goods via suspended tracks.

Devices to be transported 3 orbitals Detailed Implementation

[0031] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the present utility model is further described below in conjunction with specific illustrations. However, this utility model is not limited to the embodiments described below.

[0032] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0033] Currently, existing main equipment that needs to move on tracks is equipped with a traveling mechanism, which is mostly integrated into the equipment design, resulting in a relatively large overall size of the main equipment. Since electrical equipment has a higher failure rate than mechanical structures during operation, and when maintenance is required, because it is located inside the main equipment, the entire main equipment must be removed from the track for repair. This makes the disassembly and assembly process cumbersome, time-consuming, and labor-intensive, thus hindering the normal operation of the entire equipment and significantly delaying production and operational efficiency.

[0034] To solve the above problems, this utility model provides a traction drive device 1 for use in suspended tracks.

[0035] like Figures 1 to 3 As shown, the traction drive device 1 applied to the suspended track in this embodiment includes a drive module 11 and a traction module 12. The drive module 11 is detachably connected to the external transport device 2 via the traction module 12.

[0036] This structural design allows the traction drive device 1 to be removed from the track 3 when the drive module 11 malfunctions, and a working traction drive device 1 can be installed on the track 3 to continue traction of the transported device 2 on the track 3. This ensures that the transported items on the track 3 can continue to be transported normally, avoiding the problem of having to remove the transported items from the track 3 when repairing the traction components, which would affect production and transportation progress and effectively improve production efficiency.

[0037] like Figure 4 As shown, the traction drive device 1 applied to the suspended track can be installed on the suspended track 3, wherein the drive module 11 drives the device 2 to be transported on the track 3 to move through the traction module 12. Figure 4 The diagram is only used to illustrate the usage state of the traction drive device 1 of the suspended track, and is not used to specifically limit the transport device 2. In actual applications, the transport device 2 can be in other structural states, or even another track. That is, the traction drive device applied to the suspended track in this embodiment can also be used to traction the track, and is not limited to the example shown in the diagram.

[0038] like Figures 5 to 9 As shown, the drive module 11 in this embodiment includes a bearing unit 111, a moving drive unit 112, a self-locking telescopic unit 113, and a driven wheel unit 114. The supporting unit 111 includes a first supporting mechanism 1111 and a second supporting mechanism 1112. In this embodiment, the first supporting mechanism 1111 includes a first fixing plate 11111, and the second supporting mechanism 1112 includes a second fixing plate 11121 and a third fixing plate 11122. The second fixing plate 11121 and the third fixing plate 11122 are respectively located on both sides of the moving drive unit 112. The second fixing plate 11121 and the third fixing plate 11122 have basically the same shape, and their areas are only different in that the moving drive unit 112 is fixed on the third fixing plate 11122.

[0039] The first connection point of the first support mechanism 1111 is movably connected to the first connection point of the second support mechanism 1112. In this embodiment, the first connection point of the first support mechanism 1111 and the first connection point of the second support mechanism 1112 are hinged to form a first hinge point 1113 at the connection position. The second connection point of the first support mechanism 1111 is connected to the second connection point of the second support mechanism 1112 through the self-locking telescopic unit 113. In this embodiment, the second connection point of the first support mechanism 1111 is hinged to the self-locking telescopic unit 113 to form a second hinge point 1114 at the connection position. The second connection point of the second support mechanism 1112 is hinged to the self-locking telescopic unit 113 to form a third hinge point 1115 at the connection position. By utilizing the design of the first hinge point 1113, the second hinge point 1114 and the third hinge point 1115, it is possible to make the second bearing mechanism 1112 swing relative to the first bearing mechanism 1111 by controlling the extension and retraction of the self-locking telescopic unit 113.

[0040] In other embodiments, in addition to being connected by a hinge, the first connection point of the first support mechanism 1111 and the first connection point of the second support mechanism 1112 can also be provided with a self-locking telescopic unit 113 of a certain specification, which can also achieve the relevant functions.

[0041] In this embodiment, the self-locking telescopic unit 113 is used to form the telescopic control component, thereby realizing the self-locking function.

[0042] The mobile drive unit 112 includes a drive mechanism 1121 and a drive wheel 1122. The drive mechanism 1121 is connected to the second support mechanism 1112, and the drive wheel 1122 is connected to the output component of the drive mechanism 1121. The drive mechanism 1121 may be composed of a servo motor. The driven wheel unit 114 includes several driven wheels 1141 (i.e., traveling wheels) disposed on the first bearing mechanism 1111. The illustrated example shows four driven wheels 1141, but in actual implementation, this is not a limitation. Figure 4 As shown, when the traction drive device 1 is installed on the track, the driven wheel 1141 will be attached to the track. The driven wheel 1141 is not directly connected to the power source. It will only rotate relative to the track when the mobile drive unit 112 is in contact with the track and is running.

[0043] Using the above structure, the second bearing mechanism 1112 can drive the mobile drive unit 112 to move closer to or away from the first bearing mechanism 1111 by adjusting the extension state of the self-locking telescopic unit 113, thereby realizing the approach and separation between the drive wheel 1122 and the driven wheel 1141. Figure 6 The diagram shows the relative positions of the moving drive unit 112 and the first supporting mechanism 1111 in the first state of the traction drive device 1 applied to the suspended track. Figure 7 This is a schematic diagram showing the relative positions of the moving drive unit 112 and the first bearing mechanism 1111 in the second state of the traction drive device 1 applied to the suspended track in one embodiment (for ease of showing the position change of the drive wheel 1122). Figure 6 and Figure 7 The third fixing plate 11122 is omitted in the text. Figure 6 In the indicated state, the drive wheel 1122 is close to the driven wheel 1141, which facilitates the transmission of kinetic energy to the track, thereby ensuring that the traction drive device 1 can move or brake under the drive of the drive wheel 1122. Figure 7 In the state shown, the drive wheel 1122 is away from the driven wheel 1141, thereby preventing the drive wheel 1122 from transmitting kinetic energy to the track, thus preventing the kinetic energy from being transmitted to the track. In this state, it is also easier to remove the traction drive device 1 from the track.

[0044] like Figures 8A to 9 As shown, in this embodiment, the self-locking telescopic unit 113 includes a motor mechanism 1131, a self-locking screw mechanism 1132, and a third bearing mechanism 1133; The third load-bearing mechanism 1133 includes a traction frame component 11331 and a motor load-bearing component 11332; The self-locking screw mechanism 1132 includes a screw 11321, a nut 11322, and an elastic component.

[0045] The traction frame component 11331 has a receiving cavity, and the nut 11322 is located within the receiving cavity. The nut 11322 at least partially abuts against the inner wall of the receiving cavity, so that there is no relative rotation between the nut 11322 and the traction frame component 11331. In this embodiment, the nut 11322 is a trapezoidal nut, such as... Figure 9 As shown, the trapezoidal nut 11322 in this instance class has an edge that forms a rectangular structure that fits against the inner wall of the receiving cavity, thereby preventing the trapezoidal nut from rotating within the receiving cavity.

[0046] The elastic component is sleeved on the lead screw 11321 and is located between the nut 11322 and the motor-adjacent end of the traction frame component 11331. The elastic component may include a spring 11323. This elastic component provides preload to the self-locking telescopic unit 113, thereby ensuring better contact between the moving drive unit 112 and the track, thus ensuring the smoothness of the traction drive device 1 during movement. One end of the lead screw 11321 is connected to the output part of the motor mechanism 1131, and the other end of the lead screw 11321 extends through the through hole on the motor adjacent end of the traction frame component 11331 into the receiving cavity, so that the lead screw 11321 is threadedly connected to the nut 11322. The lead screw 11321 extends to one end of the receiving cavity and is provided with a first limiting component. In this embodiment, the lead screw 11321 cover located at the end of the lead screw 11321 away from the motor 11311 constitutes the first limiting component, so as to limit the first extreme position of the self-locking telescopic unit 113 and prevent the nut 11322 from disengaging from the lead screw 11321.

[0047] The lead screw 11321 is provided with a second limiting component at one end located outside the traction frame component 11331. The second limiting component is composed of a first retaining spring 11325 located on the lower side of the traction frame component 11331, so as to ensure a better connection between the traction frame component 11331 and the lead screw 11321, effectively play a limiting role, and prevent the lead screw 11321 from slipping off.

[0048] like Figure 9 As shown, in this embodiment, a connector 1135 is used to ensure that the motor 11311 can be better fixed on the motor bearing member 11332. At the same time, a second snap ring 11326 is also provided in this embodiment to ensure that the lead screw 11321 can be better connected to the output shaft 113111 of the motor.

[0049] The motor bearing member 11332 is provided with a first through hole 113321 coaxially arranged with the lead screw 11321, and the motor bearing member 11332 is also provided with a second through hole 113322 perpendicular to the lead screw 11321; A first bearing 1134 is provided inside the first through hole 113321, and the lead screw 11321 passes through the first bearing 1134, thereby ensuring that the rotation of the lead screw 11321 is more flexible. The second bearing is provided in the second through hole 113322. The second connection point of the second bearing mechanism 1112 is hinged to the motor bearing component 11332 through the second bearing in the second through hole 113322. The second bearing can be made of the bearing in the prior art, so the second bearing is not directly drawn in the figure.

[0050] With the above structure, the traction frame component 11331 can be hinged to the second connection point of the first bearing mechanism 1111, and the motor bearing component 11332 can be hinged to the second connection point of the second bearing mechanism 1112. The motor-supporting component 11332 is connected to the motor mechanism 1131, and the self-locking lead screw mechanism 1132 is connected to both the output section of the motor mechanism 1131 and the traction frame component 11331. In this embodiment, the motor mechanism 1131 includes a motor, and the output section of the motor mechanism 1131 is formed by the output shaft 113111 of the motor. The output shaft 113111 of the motor is connected to the lead screw 11321 by a key connection. This allows control of the extension state of the self-locking telescopic unit 113 to be achieved by controlling the rotation of the motor. To ensure control accuracy, the motor can be a servo motor.

[0051] like Figure 5 As shown, in this embodiment, a first connecting hole is provided on the first fixed plate 11111 to form the first connection point of the first bearing mechanism 1111. Second connecting holes are provided at corresponding positions on the second fixed plate 11121 and the third fixed plate 11122 to form the first connection points of the second bearing mechanism 1112. The second fixed plate 11121 and the third fixed plate 11122 are located on both sides of the first fixed plate 11111 and the moving drive unit 112. Then, a corresponding screw (or pin) passes through the first connecting hole and the second connecting hole to form a first hinge point 1113 at the corresponding position. The threaded end of the screw is connected to the corresponding nut (or the top end of the pin is processed so that the diameter of both ends of the pin is wider than the diameter of the corresponding connecting hole), thereby achieving the effect of preventing detachment.

[0052] In this embodiment, a third connecting hole is provided on the first fixed plate 11111 to form the second connecting point of the first bearing mechanism 1111. A fourth connecting hole is provided at the end of the traction frame component 11331 adjacent to the first fixed plate 11111 to form the first connecting point of the self-locking telescopic unit 113. Similarly, a screw (or pin) passing through the third connecting hole and the fourth connecting hole can be used to connect the traction frame component 11331 and the first fixed plate 11111, thereby forming a second hinge point 1114 at the corresponding position. The threaded end of the screw is connected to the corresponding nut (or the top end of the pin is processed so that the diameter of both ends of the pin is wider than the diameter of the corresponding connecting hole), thereby achieving the effect of preventing detachment.

[0053] In this embodiment, fifth connecting holes are respectively provided at corresponding positions on the second fixing plate 11121 and the third fixing plate 11122 to form the second connecting points of the second bearing mechanism 1112. A bolt (or pin) is passed through the fifth connecting hole on the second fixing plate 11121 and connected to the second bearing in the second through hole 113322 of the motor bearing member 11332. Another bolt is passed through the fifth connecting hole on the third fixing plate 11122 and connected to the second bearing in the second through hole 113322 on the other side of the motor bearing member 11332. Thus, a third hinge point 1115 is formed at the corresponding position. The threaded end of the screw is connected to the corresponding nut (or the top end of the pin is processed so that the diameter of both ends of the pin is wider than the diameter of the corresponding connecting hole), thereby achieving the effect of preventing detachment.

[0054] In this embodiment, the three hinge points are connected by a pin to form a triangular structure. The pin restricts axial movement while allowing free rotation, thereby ensuring that the first bearing mechanism 1111 and the second bearing mechanism 1112 can open and close around the first hinge point 1113 under the control of the self-locking telescopic unit 113.

[0055] Other methods may be used to implement the hinge in other embodiments, and it is not limited to the embodiments described above.

[0056] In this embodiment, the traction module 12 includes two traction rods 121; One end of the traction rod 121 is hinged to the first bearing mechanism 1111, and the other end of the traction rod 121 is used for detachable connection with the device 2 to be transported. Figure 5 As shown, the corresponding bolts are passed through the corresponding through holes on the traction rod 121 and the first bearing mechanism 1111 and then connected to the nut to realize the rotational connection between the traction rod 121 and the first bearing mechanism 1111. Alternatively, the corresponding pins can be used to realize the hinge connection between the two.

[0057] The supporting unit 111 further includes a fourth supporting mechanism 115, which is connected to the second supporting mechanism 1112. The fourth supporting mechanism 115 supports the first drive control component 1123 and the second drive control component 113112. The first drive control component 1123 is connected to the mobile drive unit 112, and the second drive control component 113112 is connected to the self-locking telescopic unit 113. Specifically, the first drive control component 1123 controls the mobile drive unit 112, and the second drive control component 113112 controls the self-locking telescopic unit 113. The first drive control component 1123 and the second drive control component 113112 can be controlled by a remote control device, rather than having the human-machine interface control components directly mounted on them.

[0058] The first drive control component 1123 controls the drive mechanism 1121, which can also be a motor. The first drive control component 1123 controls the start, stop, and forward / reverse rotation of the motor, thereby controlling the forward, backward, or stop movement of the traction drive device 1. The second drive control component 113112 controls the motor in the self-locking telescopic unit 113. By controlling the forward and reverse rotation of this motor, the lead screw 11321 rotates forward and backward relative to the nut 11322, thereby controlling the extension of the self-locking telescopic unit 113. That is, the first drive control component 1123 and the second drive control component 113112 can each be composed of a corresponding motor driver. In specific implementations, both the first drive control component 1123 and the second drive control component 113112 can be composed of independent control components from the prior art, or they can be composed of the same control component. Their specific configuration is not the focus of this design; therefore, their specific structure is not described in this application.

[0059] Since this embodiment uses a motor mechanism 1131 to control the extension and retraction of the self-locking telescopic unit 113, only circuit control is required, and no additional air circuit is needed. The overall structure is simple and easy to assemble and disassemble.

[0060] To facilitate understanding, the following will be combined with Figures 6 to 9 The operating principle of the traction drive device 1 applied to the suspended track is further explained: like Figure 6 and Figure 7As shown, the triangular structure formed by the three hinge points on the first bearing mechanism 1111, the second bearing mechanism 1112 and the self-locking telescopic unit 113, the drive wheel 1122 is connected to the second bearing mechanism 1112 through the drive mechanism 1121, and the drive wheel 1122 is located between the triangular structure formed by the three hinge points, forming a floating connection structure design.

[0061] The output shaft of the motor mechanism 1131 in the self-locking telescopic unit 113 is connected to the lead screw 11321 in the self-locking lead screw mechanism 1132. The connection method can be found in [reference needed]. Figures 8A to 9 As shown. When the output shaft of the motor mechanism 1131 rotates, since the trapezoidal nut in the self-locking screw mechanism 1132 is located in the receiving cavity of the traction frame component 11331 and the trapezoidal nut is in contact with the inner wall of the traction frame component 11331, no relative rotation will occur. Therefore, when the output shaft of the motor mechanism 1131 rotates, the traction frame component 11331 will move away from or closer to the motor mechanism 1131 along with the trapezoidal nut, thereby enabling the self-locking telescopic unit 113 to perform relative extension and retraction actions. Furthermore, since both the first hinge point 1113 and the third hinge point 1115 are located on the first bearing mechanism 1111, the second bearing mechanism 1112 and the traction frame component 11331 at the corresponding positions will not move relative to the first bearing mechanism 1111 except by rotation. The second hinge point 1114 is used to connect the motor bearing component 11332 and the second bearing mechanism 1112, so that when the output shaft of the motor mechanism 1131 rotates, the second hinge point 1114 will move closer to or further away from the first bearing mechanism 1111, thereby driving the drive wheel 1122 to make an arc motion relative to the first hinge point 1113, forming a swing mechanism, thereby realizing the up and down swing of the drive wheel 1122 relative to the first bearing mechanism 1111. When the drive wheel 1122 moves upward, its upper surface contacts and adheres to the lower surface of the track contact surface, forming an elastic force between them. The traction drive device 1 (i.e., the traveling mechanism) is in the engaged state. The drive mechanism 1121, which is composed of a servo motor, can drive the drive wheel 1122 to rotate and generate static friction with the track, thereby driving the traction drive device 1 (i.e., the traveling mechanism) to move on the track. When the motor mechanism 1131 rotates in the reverse direction, the first bearing mechanism 1111 in the area of ​​the second hinge point 1114 moves downward, driving the drive wheel 1122 to move downward, so that the drive wheel 1122 no longer contacts the track contact surface, and the traction drive device 1 (i.e., the traveling mechanism) is in the disengaged state at this time.

[0062] In the self-locking telescopic unit 113, the motor mechanism 1131 is mounted on the motor support member 11332. The motor support member 11332 presses against the second bearing through a stepped structure at the second through hole 113322. The motor support member 11332 also has a first through hole 113321 through which the lead screw 11321 passes, so that the lead screw 11321 can be connected to the output shaft of the motor mechanism 1131. A first retaining ring 11325 is provided below the lead screw 11321 to prevent the lead screw 11321 from slipping out. The threaded portion of the lead screw 11321 is screwed into a trapezoidal nut and inserted into the traction frame member 11331. An elastic assembly consisting of two spring bodies (i.e., springs 11323) is provided between the trapezoidal nut and the traction frame member 11331. A limit cap 11324 is provided at the top of the lead screw 11321 to prevent the lead screw 11321 from sliding out of the trapezoidal nut.

[0063] When the output shaft of the motor mechanism 1131 rotates clockwise, the lead screw 11321 drives the trapezoidal nut to move downwards. The three-hinged structure causes the drive wheel 1122 to swing upwards and contact the track. The output shaft of the motor mechanism 1131 continuously outputs power, and the drive wheel 1122 forms a preload on the track through the spring body. Even when the track contact surface is uneven, the drive wheel 1122 can still maintain contact with the track through the preload. The shape of the trapezoidal nut fits the contour of the inner wall of the traction frame component 11331 to prevent self-rotation. At the same time, it forms a self-locking structure with the thread of the lead screw 11321. That is, the rotation of the lead screw 11321 can push the trapezoidal nut, but the pressure or tension of the trapezoidal nut cannot rotate the motor. Through this structure, even when the motor is powered off or cannot provide torque output, the drive wheel 1122 can still maintain contact with the track through the preload, thus allowing the traction drive device 1 to remain relatively stationary with the track.

[0064] The beneficial effects of this utility model on the traction drive device applied to suspended tracks are as follows: The traction drive device applied to the suspended track includes a drive module 11 and a traction module 12. The drive module 11 is detachably connected to the external transport device 2 through the traction module 12, so that when the traction drive device malfunctions, worn parts can be disassembled and replaced separately without affecting the normal use of the external transport device 2, thus ensuring the overall operating efficiency of the transport device. The drive module 11 includes a load-bearing unit 111, a moving drive unit 112, and a self-locking telescopic unit 113. The load-bearing unit 111 includes a first load-bearing mechanism 1111 and a second load-bearing mechanism 1112. The first connection point of the first load-bearing mechanism 1111 is movably connected to the first connection point of the second load-bearing mechanism 1112. The second connection point of 1 is connected to the second connection point of the second bearing mechanism 1112 through the self-locking telescopic unit 113; by adjusting the telescopic state of the self-locking telescopic unit 113, the second bearing mechanism 1112 drives the mobile drive unit 112 to move closer to or away from the first bearing mechanism 1111, thereby controlling whether the mobile drive unit 112 is in contact with the track. This satisfies the control of the driving module 11's driving and braking functions using the mobile drive unit 112, and also ensures that the traction drive device is easy to disassemble. At the same time, since the device uses the self-locking telescopic unit 113, it avoids the relative displacement of the first bearing mechanism 1111 and the second bearing mechanism 1112 under the action of gravity, thus improving the reliability of the traction drive device during use.

[0065] The elastic component in the self-locking screw mechanism 1132 provides preload, allowing the drive wheel 1122 to continuously contact the track surface. The self-locking structure formed by the trapezoidal nut and the screw 11321 ensures that the drive wheel 1122 maintains preload even when the clutch motor stops outputting, guaranteeing continued engagement with the track even after power failure. This structural design, utilizing the spring's energy storage mechanism, allows the drive wheel 1122 to maintain continuous contact when rolling on uneven track surfaces, ensuring smooth operation during transport.

[0066] Furthermore, both the mobile drive unit 112 and the self-locking telescopic unit 113 in this embodiment use motors as power sources, making the axis during installation simpler and easier to install and control.

[0067] This traction drive device is characterized by its ease of use, convenient disassembly, individual replacement capability, high reliability, and strong adaptability, effectively ensuring the operational efficiency of equipment transporting goods via suspended tracks.

[0068] In the traction drive device technical solution of this utility model applied to suspended tracks, each of the included functional modules and module units can correspond to specific hardware circuits in the integrated circuit structure. Therefore, it only involves the improvement of specific hardware circuits. The hardware part is not merely a carrier for executing control software or computer programs. Thus, solving the corresponding technical problems and obtaining the corresponding technical effects does not involve the application of any control software or computer programs. In other words, this utility model can solve the technical problems and obtain the corresponding technical effects simply by improving the hardware circuit structure involved in these modules and units, without the need for specific control software or computer programs to achieve the corresponding functions.
