Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a stacker crane with a guide device for aisle access. Background Technology

[0002] In the current cigarette manufacturing process, stacker cranes are widely used in filter rod transportation due to their flexibility, efficiency, safety, reliability, and wide applicability. However, the operational stability of the stacker crane significantly impacts the filter rod transportation efficiency; therefore, ensuring the normal and steady-state operation of the entire stacker crane is crucial.

[0003] However, due to the severe wear of the guide wheels in the guide device of the stacker crane during long-term use, the guiding function of the guide wheels fails, reducing the service life of the guide wheels and causing the entire stacker crane to be unable to move in a straight line, resulting in problems such as deviation or even tipping over, and making it impossible to guarantee the normal steady-state operation of the entire stacker crane.

[0004] To address the above problems, there is an urgent need for a stacker crane with a guiding device for roadways. Utility Model Content

[0005] The purpose of this utility model is to propose a roadway stacker with a guiding device, which enables the first guide wheel and the second guide wheel to simultaneously provide guidance to the traveling mechanism, so as to ensure the guiding effect on the traveling mechanism, and can replace the first guide wheel in time when the wear of the first guide wheel reaches the maximum allowable wear value, thereby improving the maintenance accuracy, applicability and durability of the entire guiding device.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0015] As an alternative, along the X-axis, the distance between the axis of the first mounting through hole and the axis of the second mounting through hole is greater than the outer diameter of the second guide wheel.

[0016] As an optional solution, the first guide wheel includes:

[0017] The roller shaft has its top end coaxially extending upward along the Z-axis to the outside of the first mounting through hole. The top part of the roller shaft extending out of the first mounting through hole is threaded with a locking nut, and the locking nut can abut against the top surface of the first support plate.

[0018] A bushing is fitted over the roller shaft and located inside the first mounting through hole;

[0019] A bushing is fitted over the bushing and positioned at the bottom end of the roller shaft;

[0020] The guide wheel is sleeved outside the bushing and spaced below the first support plate. The guide wheel is used to rotate and abut against the side of the ground rail.

[0021] As an optional solution, the guiding component further includes:

[0022] An anti-tipping wheel is rotatably connected to one side of the folded support plate around the Y-axis. The anti-tipping wheel is used to rotatably support the walking mechanism and is located close to the first guide wheel.

[0023] As an optional feature, the guiding device further includes:

[0024] A detection component is connected to the bracket and the second guide wheel. The detection component is used to detect whether the second guide wheel rotates and abuts against the side of the ground rail.

[0025] As an optional solution, the detection component includes:

[0026] An angle bracket, the top of which is connected to the support;

[0027] The sensor is threaded along the Z-axis to the bottom end of the bracket;

[0028] The detection screw is slidably connected to the second guide wheel along the Z-axis, and the sensor is positioned directly above the detection screw;

[0029] Indicator light, which is communicatively connected to the sensor;

[0030] A buzzer is communicatively connected to the sensor.

[0031] As an optional solution, the top of the bracket is provided with a long straight slot extending along the Y-axis, the bracket is provided with a mounting hole, the fastening bolt can move along the Y-axis within the long straight slot, and the fastening bolt can be threaded into the long straight slot and the mounting hole.

[0032] As an optional solution, the ground track includes:

[0033] Base plate, fixed installation;

[0034] A vertical plate is vertically connected to the base plate, and the first guide wheel or the second guide wheel is used to rotate and abut against the side of the vertical plate;

[0035] A supporting top plate is connected to the top of the vertical plate and is arranged parallel to the bottom plate to form the ground track with an I-shaped structure. The traveling mechanism is slidably mounted on the supporting top plate along the X-axis.

[0036] As an optional solution, the walking mechanism includes:

[0037] A support bracket, wherein the bracket is connected to the support bracket;

[0038] The traveling wheel is rotatably mounted inside the support bracket around the Y-axis. The traveling wheel can rotate on the support top plate so that it can drive the support bracket to move along the X-axis.

[0039] The beneficial effects of this utility model are as follows:

[0040] By sliding the traveling mechanism along the X-axis to the top of the ground rail, the entire stacker crane with the guiding device can move linearly along the X-axis. Simultaneously, a support is connected to the traveling mechanism, and the first and second guide wheels are rotatably connected to the support at intervals along the X-axis. When the first guide wheel rotates and abuts against the side of the ground rail, the second guide wheel does not rotate and abut against the side of the ground rail. This allows the first guide wheel to provide guidance for the traveling mechanism, ensuring that the traveling mechanism can only move along the X-axis on the ground rail and will not deviate from its path. During the process of the first guide wheel rotating and abutting against the side of the ground rail, the first guide wheel will wear, causing its outer diameter to decrease. This affects the rotational abutment effect between the first guide wheel and the side of the ground rail, causing a slight deviation in the traveling mechanism's trajectory to one side. At this point, since the wear value of the first guide wheel is within the maximum allowable wear range, the traveling mechanism will not tip over. When the wear value of the first guide wheel reaches the maximum allowable wear value, this… At the same time, the wear of the first guide wheel will cause a slight offset in the entire traveling mechanism. This offset will cause the second guide wheel to offset and rotate to abut against the side of the ground rail. This allows both the first and second guide wheels to simultaneously abut against the side of the ground rail, providing dual guidance for the traveling mechanism. That is, the guidance changes from single guide wheel guidance to dual guide wheel guidance. On the one hand, this reduces the stress on the first guide wheel, preventing further wear and thus preventing the guiding function from failing due to further wear. This better protects the first guide wheel, improving the applicability and durability of the entire guiding device and extending the service life of the guiding device and the entire stacker crane with the guiding device. On the other hand, the guiding effect of the dual guide wheels ensures better guidance for the traveling mechanism, thus better preventing the traveling path of the traveling mechanism from deviating relative to the X-axis. This better ensures the normal and steady-state operation of the entire stacker crane with the guiding device.

[0041] By setting up a detection component, the system can detect when the second guide wheel rotates and abuts against the side of the ground rail. At this point, the first guide wheel and the second guide wheel together provide guidance for the traveling mechanism. This allows the first guide wheel to be replaced promptly and quickly without stopping the entire stacker crane with the guiding device, while the second guide wheel is guiding the traveling mechanism. This improves the overall working efficiency of the stacker crane with the guiding device. Furthermore, since the first guide wheel is replaced promptly after reaching its maximum allowable wear value, it prevents the first guide wheel from continuing to provide guidance and abutment, thus avoiding accelerated wear and misalignment of the traveling mechanism and the second guide wheel. This significantly improves the accuracy of fault repair for the entire stacker crane with the guiding device. At the same time, since only the first guide wheel needs to be replaced, and the traveling mechanism and the second guide wheel do not need to be replaced, maintenance efficiency is improved, thereby enhancing the operational stability of the entire stacker crane with the guiding device.

Throughout this specification, the same reference numerals indicate the same elements.

[0060] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0061] This embodiment proposes a stacker crane with a guide device. The stacker crane with the guide device can use double wheel guidance to provide guidance, avoid movement deviation during operation, and ensure that the entire stacker crane with the guide device can move linearly along the X-axis, thereby ensuring the normal steady-state operation of the entire stacker crane with the guide device.

[0062] It is worth noting that the improvement in this embodiment focuses on the specific structural design of the guiding device. Therefore, other structures and working principles of the stacker crane with the guiding device will not be described in detail here. You can refer to the stacker cranes commonly found in the prior art.

[0063] Specifically, such as Figures 1 to 4 As shown, the stacker crane with a guide device includes a ground rail 1, a traveling mechanism 2, and a guide device 3. The ground rail 1 extends along the X-axis. The traveling mechanism 2 is slidably mounted on the top of the ground rail 1 along the X-axis, that is, the conveying direction of the traveling mechanism 2 is parallel to the X-axis. The guide device 3 includes a guide assembly 31, which includes a bracket 311, a first guide wheel 312, and a second guide wheel 313. The bracket 311 is connected to the traveling mechanism 2, that is, the bracket 311 moves synchronously with the traveling mechanism 2. The first guide wheel 312 and the second guide wheel 313 are spaced apart along the X-axis and rotatably connected to the bracket 311. The first guide wheel 312 is used to rotatably abut against the side of the ground rail 1. When the first guide wheel 312 reaches the maximum allowable wear value, the traveling mechanism 2 can drive the second guide wheel 313 to deflect and rotatably abut against the side of the ground rail 1.

[0064] By sliding the traveling mechanism 2 along the X-axis to the top of the ground rail 1, the entire stacker crane with the guiding device can move linearly along the X-axis. At the same time, the support 311 is connected to the traveling mechanism 2, and the first guide wheel 312 and the second guide wheel 313 are rotatably connected to the support 311 at intervals along the X-axis. When the first guide wheel 312 rotates and abuts against the side of the ground rail 1, the second guide wheel 313 does not rotate and abut against the side of the ground rail 1. This allows the first guide wheel 312 to provide guidance for the traveling mechanism 2, ensuring that the traveling mechanism 2 can only move along the X-axis on the ground rail 1 and will not deviate from its course.

[0065] Compared to existing technologies, the stacker crane with a guiding device in this embodiment is equipped with a first guide wheel 312 and a second guide wheel 313 that have a rotational contact time difference with the side of the ground rail 1. Firstly, the first guide wheel 312 provides guidance to the traveling mechanism 2. During the rotational contact of the first guide wheel 312 with the side of the ground rail 1, wear occurs, reducing its outer diameter and affecting the rotational contact effect between the first guide wheel 312 and the side of the ground rail 1. This causes a slight deviation in the traveling trajectory of the traveling mechanism 2 to one side. At this time, since the wear value of the first guide wheel 312 is within the maximum allowable wear range, the traveling mechanism 2 will not be at risk of tipping over. When the wear value of the first guide wheel 312 reaches the maximum allowable wear value, the wear of the first guide wheel 312 will cause a slightly larger deviation in the entire traveling mechanism 2, thus mitigating the risk of tipping over. The second guide wheel 313 is offset to rotate and abut against the side of the ground rail 1, so that the first guide wheel 312 and the second guide wheel 313 can simultaneously abut against the side of the ground rail 1 to provide dual guidance for the traveling mechanism 2, that is, the guidance is changed from single guide wheel guidance to dual guide wheel guidance. On the one hand, it can reduce the stress on the first guide wheel 312 and avoid further wear of the first guide wheel 312, thereby preventing the problem of guidance function failure caused by further wear of the first guide wheel 312, thus better protecting the first guide wheel 312, improving the applicability and durability of the entire guiding device 3, and extending the service life of the guiding device 3 and the entire roadway stacker crane with the guiding device. On the other hand, the guiding effect of the dual guide wheels can ensure better guidance of the traveling mechanism 2, thereby better preventing the traveling path of the traveling mechanism 2 from deviating relative to the X-axis, thus better ensuring the normal steady-state operation of the entire roadway stacker crane with the guiding device.

[0066] Specifically, such as Figures 1 to 4 As shown, the bracket 311 includes a first support plate 3111, a second support plate 3112, and a folded support plate 3113. The first support plate 3111 extends along the X-axis and has a first mounting through hole 3114 and a second mounting through hole 3115 spaced apart. A first guide wheel 312 is coaxially mounted in the first mounting through hole 3114, and a second guide wheel 313 is coaxially mounted in the second mounting through hole 3115. The second support plate 3112 extends along the Z-axis and is connected to the traveling mechanism 2. One end of the folded support plate 3113 is connected to the connection position between the first support plate 3111 and the second support plate 3112, and the other end of the folded support plate 3113 extends along the X-axis and is located below the traveling mechanism 2. This allows the first support plate 3111, the second support plate 3112, and the folded support plate 3113 to be connected to each other to form a herringbone structure bracket 311.

[0067] By setting the aforementioned herringbone-shaped support 311, the overall layout of the support 311 is reasonable, the structure is simple, and the cost is low. Furthermore, the support 311 provides a stable and reliable mounting base for the first guide wheel 312 and the second guide wheel 313. In this embodiment, the first support plate 3111, the second support plate 3112, and the folded support plate 3113 can be integrally formed. In other embodiments, the first support plate 3111, the second support plate 3112, and the folded support plate 3113 can also be separate structures; no specific limitation is made here.

[0068] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, along the Y-axis, the distance between the axis of the first mounting through hole 3114 and the axis of the second mounting through hole 3115 is equal to the maximum permissible wear value of the first guide wheel 312. On one hand, this ensures that when the first guide wheel 312 initially rotates and abuts against the side of the ground rail 1, there is a certain gap between the second guide wheel and the side of the ground rail 1 on the Y-axis, allowing the first guide wheel 312 to guide the traveling mechanism 2 independently. On the other hand, when the wear value of the first guide wheel 312 reaches the maximum permissible wear value, its outer diameter decreases due to wear, thus increasing the gap between the first guide wheel 312 and the side of the ground rail 1 on the Y-axis to the maximum permissible wear value. This causes the traveling mechanism 2 to shift, allowing it to move the second guide wheel 313 closer to the side of the ground rail 1 by the maximum permissible wear value, enabling the second guide wheel 313 to directly rotate and abut against the side of the ground rail 1. Specifically, the maximum permissible wear value can be 3mm. Here, the specific value of the maximum allowable wear value is not limited, and needs to be determined based on the wear condition of the first guide wheel 312 and the actual guiding requirements.

[0069] like Figure 5 As shown, by making the distance between the axis of the first mounting through hole 3114 and the axis of the second mounting through hole 3115 equal to the maximum allowable wear value of the first guide wheel 312 along the Y-axis, it can be ensured that when the wear value of the first guide wheel 312 reaches the maximum allowable wear value, the second guide wheel 313 can automatically rotate and abut against the side of the ground rail 1. The automatic operation of the second guide wheel 313 can provide guidance for the walking mechanism 2, realizing the change from single guide wheel guidance to double guide wheel guidance, thereby improving the applicability and durability of the entire guiding device 3.

[0070] Specifically, such as Figures 1 to 4As shown, along the X-axis, the distance between the axis of the first mounting through hole 3114 and the axis of the second mounting through hole 3115 is greater than the outer diameter of the second guide wheel 313, so as to provide a larger installation space for the second guide wheel 313, thereby avoiding installation interference between the first guide wheel 312 and the second guide wheel 313.

[0071] Specifically, in this embodiment, the structure of the first guide wheel 312 is basically the same as that of the second guide wheel 313. Therefore, the specific structure of the first guide wheel 312 will be described in detail below. The structure of the second guide wheel 313 can be referred to the structural description of the first guide wheel 312. Here, the specific structure of the second guide wheel 313 will not be described in detail.

[0072] Furthermore, such as Figure 6 and Figure 7 As shown, the first guide wheel 312 includes a roller shaft 3121, a bushing, a bushing 3122, and a guide wheel 3123. The top end of the roller shaft 3121 extends coaxially upward along the Z-axis to the outside of the first mounting through hole 3114. A locking nut 3125 is threadedly tightened onto the top part of the roller shaft 3121 extending to the outside of the first mounting through hole 3114. The locking nut 3125 can abut against the top surface of the first support plate 3111, so that the roller shaft 3121 can be locked onto the first support plate 3111 by the locking nut 3125. The bushing is sleeved on the outside of the roller shaft 3121 and located inside the first mounting through hole 3114. The bushing 3122 is sleeved on the outside of the bushing and located at the bottom end of the roller shaft 3121. The guide wheel 3123 is sleeved on the outside of the bushing 3122 and spaced below the first support plate 3111. The guide wheel 3123 is used to directly rotate and abut against the side of the ground rail 1.

[0073] Specifically, such as Figures 1 to 3 As shown, the guide assembly 31 also includes an anti-tipping wheel 314. The anti-tipping wheel 314 is rotatably connected to one side of the folded support plate 3113 around the Y-axis. The anti-tipping wheel 314 is used to rotatably support the walking mechanism 2. That is, during the movement of the walking mechanism 2 along the X-axis, the anti-tipping wheel 314 rotatably supports the entire walking mechanism 2 around the Y-axis, and the anti-tipping wheel 314 is set close to the first guide wheel 312.

[0074] By setting the anti-tipping wheel 314 to rotate around the Y-axis to support the entire traveling mechanism 2, a stable support can be provided for the traveling mechanism 2. When the wear value of the first guide wheel 312 has not reached the maximum allowable wear value, even if the first guide wheel 312 wears and causes the entire traveling mechanism 2 to have a small deviation, the traveling mechanism 2 can still move normally in a straight line along the X-axis under the stable support of the anti-tipping wheel 314, thereby ensuring that the entire roadway stacker crane with the guiding device will not be at risk of tipping over.

[0075] Specifically, such as Figures 1 to 3 As shown, two anti-tipping wheels 314 are provided, arranged side by side along the X-axis, so that the support effect on the traveling mechanism 2 can be more stable through the simultaneous use of two anti-tipping wheels 314. Here, the specific number of anti-tipping wheels 314 is not limited.

[0076] Currently, due to wear on the first guide wheel 312 during operation, the entire stacker crane with the guide device is only shut down by the operator when the first guide wheel 312 has completely lost its guiding function, in order to replace the failed first guide wheel 312. This replacement method easily accelerates the wear and misalignment of the traveling mechanism 2 and the second guide wheel 313, thus greatly affecting the accuracy of fault repair for the entire stacker crane with the guide device. Furthermore, the need to shut down the machine to replace the first guide wheel 312 reduces the working efficiency of the entire stacker crane with the guide device. Moreover, because the wear and misalignment of the traveling mechanism 2 and the second guide wheel 313 are accelerated, it may also be necessary to replace the traveling mechanism 2 and the second guide wheel 313 at the same time as shutting down to replace the first guide wheel 312, further reducing maintenance efficiency.

[0077] To solve the above problems, such as Figure 1 and Figure 2 , Figure 8 and Figure 9 As shown, the guide device 3 in this embodiment also includes a detection component 32. The detection component 32 is connected to the bracket 311 and the second guide wheel 313. The detection component 32 is used to detect whether the second guide wheel 313 rotates and abuts against the side of the ground rail 1, so that the first guide wheel 312 can be replaced in time according to the detection result of the detection component 32.

[0078] Specifically, when the detection component 32 detects that the second guide wheel 313 rotates and abuts against the side of the ground rail 1, the first guide wheel 312 and the second guide wheel together provide guidance for the traveling mechanism 2. This allows the first guide wheel 312 to be replaced promptly and quickly while the second guide wheel 313 guides the traveling mechanism 2, without stopping the entire stacker crane with the guiding device. This improves the overall working efficiency of the stacker crane. Furthermore, since the first guide wheel 312 is replaced promptly after reaching its maximum allowable wear value, it prevents the first guide wheel 312 from continuing to provide guidance and abutment, thus avoiding accelerated wear and misalignment of the traveling mechanism 2 and the second guide wheel 313. This significantly improves the accuracy of fault repair for the entire stacker crane with the guiding device. Simultaneously, since only the first guide wheel 312 needs to be replaced, without replacing the traveling mechanism 2 and the second guide wheel 313, maintenance efficiency is improved, thereby enhancing the operational stability of the entire stacker crane with the guiding device.

[0079] It is worth noting that the wear of the first guide wheel 312 and the second guide wheel 313 involved in this embodiment specifically refers to the wear of the outermost guide wheel 3123, which causes its outer diameter to decrease.

[0080] Furthermore, such as Figure 1 and Figure 2 , Figure 8 and Figure 9 As shown, the detection assembly 32 includes a bracket 321, a sensor 322, a detection screw 323, an indicator light, and a buzzer. The top of the bracket 321 is connected to the first support plate 3111 of the bracket 311. The sensor 322 is threadedly connected to the bottom of the bracket 321 along the Z-axis. The detection screw 323 is slidably connected to the bushing 3122 of the second guide wheel 313 along the Z-axis, and the sensor 322 is positioned directly above the detection screw 323. The indicator light is communicatively connected to the sensor 322, and the buzzer is communicatively connected to the sensor 322.

[0081] Specifically, sensor 322 can detect whether there are obstructions within a preset detection distance. That is, when the second guide wheel 313 rotates to drive the detection screw 323 to rotate directly below the sensor 322, the sensor 322 will detect the periodic appearance of obstructions to the detection screw 323 directly below it, thus determining that the second guide wheel 313 is rotating. The sensor 322 then feeds back the detection signal to the control system. After information processing by the control system, it simultaneously controls the indicator light and buzzer, causing the indicator light to output a red alarm color and the buzzer to emit a buzzing alarm sound. This promptly alerts the staff that the wear value of the first guide wheel 312 has reached the maximum allowable wear value and that the first guide wheel 312 can be replaced in a timely manner. This guides the staff to perform preventive maintenance on the first guide wheel 312 as soon as possible, thereby improving maintenance efficiency and accuracy. The control system can adopt a control structure commonly used in existing technology. Here, the specific value of the preset detection distance is not limited and needs to be determined based on the specific detection requirements and the overall layout of the detection component 32.

[0082] Specifically, sensor 322 adopts an M8 short inductive proximity switch sensor. This M8 short inductive proximity switch sensor is small in size and easy to install, thus meeting the requirements of a compact layout and limited space for the entire guide device 3.

[0083] Specifically, such as Figure 7 and Figure 8As shown, a first threaded hole is provided on the top surface of the bushing 3122 of the second guide wheel 313, and the detection screw 323 is threaded into the first threaded hole; and a first adjusting nut 324 is threaded onto the detection screw 323, so that the installation height of the detection screw 323 relative to the top surface of the bushing 3122 of the second guide wheel 313 can be adjusted by the adjusting and fixing action of the first adjusting nut 324, thereby adjusting the distance between the detection screw 323 and the sensor 322 on the Z-axis, so as to ensure that the detection screw 323 and the sensor 322 can reach a suitable preset detection distance.

[0084] Furthermore, the corner bracket 321 is made of cast iron to ensure good structural strength of the entire corner bracket 321; such as Figure 8 and Figure 9 As shown, the corner frame 321 includes a short plate 3213, a connecting plate 3212, and a long plate 3211. The short plate 3213 is parallel to the long plate 3211, and both extend along the Y-axis. The connecting plate 3212 extends along the Z-axis, and its opposite ends are perpendicularly connected to the short plate 3213 and the long plate 3211, forming a U-shaped corner frame 321. The short plate 3213, connecting plate 3212, and long plate 3211 can be integrally formed or separate structures; no specific limitation is made here.

[0085] Specifically, such as Figure 8 and Figure 9 As shown, a second threaded hole is provided on the short plate 3213. The sensor 322 is threaded into the second threaded hole, and a second adjusting nut is threaded into the part of the sensor 322 that extends downward along the Z-axis through the second threaded hole. The length of the sensor 322 extending downward along the Z-axis through the second threaded hole can be adjusted by the adjusting and fixing action of the second adjusting nut. This allows for adjustment of the distance between the sensor 322 and the detection screw 323 on the Z-axis, so as to better ensure that the detection screw 323 and the sensor 322 can reach a suitable preset detection distance.

[0086] Furthermore, such as Figure 8 and Figure 9 As shown, the top of the bracket 321 is provided with a long straight slot 3214, that is, a long straight slot 3214 is provided on the long plate 3211 of the bracket 321. The long straight slot 3214 extends along the Y-axis, and a mounting round hole 3116 is provided on the first support plate 3111 of the bracket 311. That is, the mounting round hole 3116 is provided on the side close to the second mounting through hole 3115. The fastening bolt can move along the Y-axis in the long straight slot 3214, and the fastening bolt can be threaded into the long straight slot 3214 and the mounting round hole 3116, so that the bracket 321 can be fixed to the first support plate 3111 by the fastening bolt.

[0087] By moving the fastening bolt along the Y-axis within the long straight slot 3214, the specific position of the fastening bolt threaded into the long straight slot 3214 can be adjusted, thereby adjusting the distance of the entire bracket 321 relative to the first support plate 3111 on the Y-axis. This ensures that the sensor 322 on the bracket 321 is positioned directly above the detection screw 323, guaranteeing the alignment stability and reliability of the sensor 322 and the detection screw 323 on the Z-axis.

[0088] Specifically, such as Figure 9 As shown, two long straight slots 3214 are provided on the long plate 3211. The two long straight slots 3214 are arranged at intervals along the X-axis so that two fastening bolts can be fastened to the two long straight slots 3214 respectively. This increases the connection stability between the corner bracket 321 and the first support plate 3111, and ensures better guidance and stability for adjusting the Y-axis distance of the corner bracket 321 relative to the first support 311. Here, the specific number of long straight slots 3214 is not limited, as long as one fastening bolt is threadedly fastened into one aligned long straight slot 3214 and one mounting hole 3116.

[0089] Furthermore, such as Figure 1 As shown, the ground track 1 includes a base plate 11, a vertical plate 12, and a supporting top plate 13. The base plate 11 is fixedly installed. The vertical plate 12 is vertically connected to the base plate 11, and the guide wheel 3123 of the first guide wheel 312 or the guide wheel 3123 of the second guide wheel 313 is used to rotate and abut against the side of the vertical plate 12. The supporting top plate 13 is connected to the top of the vertical plate 12 and is parallel to the base plate 11, forming an I-shaped ground track 1. The traveling mechanism 2 slides along the X-axis on the supporting top plate 13. That is, the aforementioned guiding device 3 can effectively ensure that the traveling mechanism 2 moves linearly along the X-axis on the supporting top plate 13. The base plate 11, vertical plate 12, and supporting top plate 13 can be integrally formed or separate structures; no specific limitation is made here.

[0090] Specifically, such as Figure 1 As shown, the traveling mechanism 2 includes a support bracket 21 and traveling wheels 22; wherein, the second support plate 3112 of the bracket 311 is fastened to the support bracket 21 by threads; the traveling wheels 22 are rotatably disposed within the support bracket 21 around the Y-axis, and the traveling wheels 22 can rotate on the support top plate 13 so that the traveling wheels 22 can drive the support bracket 21 to move linearly along the X-axis. The anti-tipping wheel 314 is rotatably supported on the support bracket 21 around the Y-axis.

[0091] It is worth noting that, such as Figure 1As shown, guide devices 3 can be provided at the four corners of the support bracket 21, so that the walking mechanism 2 can be provided with more stable guidance through the four guide devices 3 at the same time. Furthermore, the structure of the guide devices 3 at the four corners of the support bracket 21 can be completely the same or different. That is, it is only necessary to ensure that a guide device 3 including a first guide wheel 312, a second guide wheel 313 and a detection component 32 is provided at at least one corner of the support bracket 21. Guide devices 3 including only the first guide wheel 312, but not the second guide wheel 313 and the detection component 32, can be provided at other corners of the support bracket 21. No specific limitation is made here.

[0092] The specific working process of the stacker crane with a guiding device in this embodiment is as follows:

[0093] Phase 1: When the first guide wheel 312 is not worn, the traveling wheel 22 of the traveling mechanism 2 rotates around the Y-axis to drive the entire traveling mechanism 2 to move linearly along the X-axis on the supporting top plate 13. At this time, among the first guide wheels 312 of each guide device 3 fixed around the traveling mechanism 2, the two sets of corresponding first guide wheels 312 opposite to each other along the Y-axis rotate to clamp the vertical plate 12, so as to provide guidance for the traveling mechanism 2 to travel and prevent the traveling mechanism 2 from deviating relative to the X-axis. At this time, since the two sets of corresponding first guide wheels 312 opposite to each other along the Y-axis simultaneously form rotational friction force on the vertical plate 12, the normal steady-state operation of the entire roadway stacker crane with guide devices can be guaranteed.

[0094] Second stage: When the first guide wheel 312 shows slight wear, the wear of the first guide wheel 312 is less than the maximum allowable wear value. As the two sets of corresponding first guide wheels 312 along the Y-axis clamp the vertical plate 12, the diameter will decrease due to wear, resulting in a reduction in the friction between the first guide wheel 312 and the vertical plate 12 of the ground rail 1. This causes the walking mechanism 2 to experience uneven force under the action of the two sets of corresponding first guide wheels 312 along the Y-axis, causing the walking trajectory of the walking mechanism 2 to deviate to one side relative to the X-axis. At this time, since the wear of the first guide wheel 312 is within the allowable range and the entire walking mechanism 2 is supported by the anti-tipping wheel 314, the walking mechanism 2 can still move stably in the second stage without the risk of tipping over.

[0095] In addition, in the second stage, the first guide wheel 312 on the side with greater force will gradually wear out due to the unilateral force, so that the wear of the first guide wheel 312 will approach the maximum allowable wear value in a short period of time.

[0096] The third stage: When the first guide wheel 312 shows significant wear, the wear of the first guide wheel 312 has reached the maximum allowable wear value, which increases the travel offset of the traveling mechanism 2 relative to the X-axis. This allows the offset traveling mechanism 2 to drive the second guide wheel 313 to move closer to the vertical plate 12, so that the second guide wheel 313 automatically rotates and abuts against the side of the vertical plate 12, and together with the first guide wheel 312, provides support and guidance for the traveling mechanism 2. Due to the automatic addition of the second guide wheel 313, the stress and wear rate of the first guide wheel 312 can be effectively reduced, thereby preventing further deviation of the travel path of the entire traveling mechanism 2 due to the severe wear of the first guide wheel 312.

[0097] Meanwhile, in the third phase, such as Figure 10 As shown, when the second guide wheel 313 rotates, the detection screw 323 fixed on the bushing 3122 of the second guide wheel 313 will rotate along with it. When the detection screw 323 rotates to the position directly below the sensor 322, the sensor 322 will detect the periodic obstruction of the detection screw 323 below, thus determining that the second guide wheel 313 is rotating, and feeding back the detection signal to the control system. After information processing by the control system, the indicator light and buzzer will be controlled simultaneously, so that the indicator light outputs a red alarm color and the buzzer emits a buzzing alarm sound, prompting the staff that the first guide wheel 312 has reached the maximum allowable wear value, so that the staff can perform preventive maintenance on the first guide wheel 312 as soon as possible, improving maintenance efficiency and accuracy.

[0098] Fourth stage: After the staff replaces the first guide wheel 312, since the first guide wheel 312 is not worn, the entire roadway stacker crane with the guiding device re-enters the first stage and starts working.

[0099] In this embodiment, the roadway stacker crane with a guiding device is equipped with a first guide wheel 312 and a second guide wheel 313 that work together. When the wear of the first guide wheel 312 reaches the maximum allowable wear value, the second guide wheel 313 will automatically rotate and abut against the ground rail 1. At the same time, the first guide wheel 312 and the second guide wheel 313 provide guidance for the traveling mechanism 2.

[0100] In this embodiment, the roadway stacker crane with a guiding device, by setting up sensors 322 and detection screws 323 that work together, can remind the staff to replace the first guide wheel 312 in time when the wear of the first guide wheel 312 reaches the maximum allowable wear value. This enables the replacement of the first guide wheel 312 without stopping the machine, and can extend the service life of the walking mechanism 2 and the second guide wheel 313, thereby improving the maintenance accuracy, applicability and durability of the entire guiding device 3.
