Description

Technical Field

[0001] This utility model belongs to the field of stacker crane technology, and specifically relates to a single-rail ring high-rise stacker crane. Background Technology

[0002] A stacker crane, also known as a stacking hoist, is a specialized crane that uses forks or booms as picking devices to grab, move, and stack unitized goods in warehouses, workshops, and other locations, or to retrieve and place unitized goods from high-level racks. The main function of a stacker crane is to move back and forth within the aisles of an automated warehouse, storing goods located at aisle entrances into rack compartments, or retrieving goods from compartments and transporting them to aisle entrances. A stacker crane consists of a frame (upper beam, lower beam, and columns), a horizontal traveling mechanism, a lifting mechanism, a loading platform, forks, and an electrical control system.

[0003] The horizontal walking mechanism of a common stacker crane is driven by a geared motor connected to the moving wheels, which in turn moves the stacker crane. However, in actual use, it has been found that due to the large walking speed and weight of the stacker crane, when the geared motor brakes, the moving wheels will cause the stacker crane to slide forward a certain distance due to inertia, resulting in low positioning accuracy of the stacker crane.

[0004] A search revealed that patent application number 202321986284.7 discloses a stacker crane walking system and a stacker crane, comprising: an H-shaped guide rail; and a stacker crane walking device disposed on the lower crossbeam of the stacker crane. The stacker crane walking device includes an axle, a guide wheel, a seated bearing, and a guide wheel mounting seat. The guide wheel and the seated bearing are sleeved on the axle. The guide wheel is a nylon wheel and abuts against the top surface of the guide rail. The guide wheel includes a wheel core and a nylon portion, with the nylon portion surrounding the wheel core. The surface of the wheel core includes a chrome-plated layer. The guide wheel mounting seat is disposed at the end of the lower crossbeam and has a receiving space. The guide wheel mounting seat also includes a side plate, and the seated bearing is mounted on the side plate. The stacker crane walking system provided in this application embodiment can reduce the noise generated by the stacker crane during movement and reduce the braking distance. Although it can reduce the braking distance to a certain extent, it does not solve the problem that the stacker crane has a large walking speed and weight. When the geared motor brakes, due to the influence of inertia, the moving wheels will drive the stacker crane to slide forward for a distance, resulting in low positioning accuracy of the stacker crane. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a single-rail circular high-rise stacker crane. When it is necessary to brake the stacker crane body, the drive mechanism drives the rotating arm to rotate, and the rotating arm drives the rotating shaft and cam to rotate. When the end of the cam is in close contact with the circular guide rail, the stacker crane body is fixed on the circular guide rail, thus ensuring the positioning accuracy of the stacker crane.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A single-rail circular high-rise stacker crane includes a circular guide rail, a stacker crane body, and a locking component. The stacker crane body is mounted on the circular guide rail and moves along the circular guide rail. An anti-tilting mechanism is provided at the bottom of the stacker crane body. The locking component includes a drive mechanism, a cam, a rotating shaft, and a rotating arm. The rotating shaft is symmetrically arranged on both sides of the stacker body. The cam is located at the bottom of the rotating shaft and cooperates with the annular guide rail. One end of the rotating arm is fixedly installed on the rotating shaft, and the other end of the rotating arm cooperates with the drive mechanism.

[0007] Preferably, the driving mechanism includes a driving cylinder and a moving plate. The piston rod of the driving cylinder is fixedly mounted on the moving plate. There are strip-shaped holes on both sides of the center line of the moving plate. A fixing column is fixedly mounted on the other end of the rotating arm. The fixing column is slidably disposed in the strip-shaped hole. The driving cylinder is used to provide power for the movement of the moving plate, ensuring the normal movement of the moving plate, and at the same time ensuring the normal operation of the locking component.

[0008] Preferably, a clearance hole is provided at the bottom of the stacker body, and a pad is provided on the side of the clearance hole away from the rotating shaft. The drive cylinder is mounted on the pad, and the moving plate is mounted in the clearance hole, with both ends of the moving plate extending to the outside of the clearance hole. The clearance hole facilitates the installation of the drive cylinder and the moving plate, ensuring the normal operation of the drive cylinder and the moving plate.

[0009] Preferably, the rotating arms are symmetrically arranged on the upper and lower sides of the moving plate, and a sliding block is also provided in the strip hole on the moving plate. The fixed column on the other end of the rotating arm on the upper and lower sides of the moving plate is rotatably mounted on the sliding block. The arrangement of the strip hole and the sliding block can ensure the normal rotation of the rotating arm.

[0010] Preferably, a sliding groove is also provided on the side wall of the strip hole, and the sliding block slides in cooperation with the sliding groove. Several grooves are also provided on one end of the cam. The sliding groove is provided to guide and limit the sliding block, preventing the sliding block from falling out of the strip hole during movement, thus ensuring the normal operation of the sliding block. The grooves can increase the friction at the end of the cam, preventing the end of the cam from sliding between the annular guide rail when braking the stacker crane body.

[0011] Preferably, the locking component further includes an upper support rod and a lower support rod, which are arranged parallel to each other, one above the other, and are fixedly installed on the stacker crane body. The rotating shaft is rotatably installed on the upper and lower support rods. The upper and lower support rods are used to support the rotating shaft and ensure the stability of the upper and lower ends of the rotating shaft during operation, thereby improving the locking effect of the locking component.

[0012] Preferably, the locking component further includes a push-pull rod, a locking plate, and a guide plate. The guide plate is disposed at the bottom of the stacker body, the locking plate is slidably mounted on the guide plate, the push-pull rod is symmetrically disposed on both sides of the guide plate, and one end of the push-pull rod is rotatably mounted on the other end of the cam. A fixed shaft is fixedly mounted on the other end of the push-pull rod, and the locking plate is slidably connected to the fixed shaft. The locking plate can fill the gap between the guide plate and the top surface of the annular guide rail, thereby increasing the friction between the guide plate and the annular guide rail and achieving the purpose of fixing the stacker body.

[0013] Preferably, the bottom of the guide plate is set as an inclined surface, which is inclined downward along the direction close to the rotation axis. A guide groove is opened on the locking plate, and the guide groove slides in cooperation with the inclined surface of the guide plate. The guide plate is set to guide the locking plate, ensuring that the locking plate can move downward along the guide plate at the same time as the push-pull rod pulls the locking plate to move, until the locking plate contacts the annular guide rail, thereby achieving the purpose of locking the stacker crane body.

[0014] Preferably, a limiting rod is provided at the edge of the inclined surface, and a limiting groove is opened on the side wall of the guide groove. The limiting groove and the limiting rod are slidably engaged. The setting of the limiting rod and the limiting groove can prevent the locking plate from falling off the guide plate and ensure that the locking plate can always move along the guide plate.

[0015] Preferably, the anti-tilt mechanism includes a horizontal plate, uprights at both ends of the horizontal plate, and guide wheels. The guide wheels are located at the bottom of the uprights. The anti-tilt mechanism can support the stacker body and prevent the stacker body from tilting during movement, thus ensuring the normal operation of the stacker body.

[0016] The beneficial effects of this utility model are: 1) When the stacker body needs to be braked, the drive mechanism drives the rotating arm to rotate, which in turn drives the rotating shaft and cam to rotate. When the end of the cam is in close contact with the annular guide rail, the stacker body is fixed on the annular guide rail, ensuring the positioning accuracy of the stacker.

[0017] 2) The drive cylinder of this device is used to provide power for the movement of the moving plate, ensuring the normal movement of the moving plate, and at the same time ensuring the normal operation of the locking parts.

[0018] 3) The clearance holes in this device facilitate the installation of the drive cylinder and the moving plate, ensuring the normal operation of the drive cylinder and the moving plate.

[0019] 4) The fixed posts on the other end of the rotating arms on the upper and lower sides of the moving plate of this device are rotatably mounted on the sliding blocks. The strip holes and the sliding blocks ensure the normal rotation of the rotating arms.

[0020] 5) The groove in this device is used to guide and limit the sliding block, preventing it from falling out of the slot during movement and ensuring its normal operation. The groove increases the friction at the end of the cam, preventing the end of the cam from sliding between the cam and the annular guide rail when braking the stacker crane body.

[0021] 6) The upper and lower support rods of this device are designed to support the rotating shaft, ensuring the stability of the upper and lower ends of the rotating shaft during operation, thereby improving the locking effect of the locking components.

[0022] 7) The locking plate of this device can fill the gap between the guide plate and the top surface of the annular guide rail, thereby increasing the friction between the guide plate and the annular guide rail and achieving the purpose of fixing the stacker crane body.

[0023] 8) The guide plate of this device is set to guide the locking plate, so as to ensure that the locking plate can move downward along the guide plate at the same time as the push-pull rod pulls the locking plate to move, until the locking plate contacts the annular guide rail, so as to achieve the purpose of locking the stacker crane body.

[0024] 9) The setting of the limiting rod and limiting groove of this device can prevent the locking plate from falling off the guide plate and ensure that the locking plate can always move along the guide plate.

[0037] In this embodiment, as Figure 4 As shown, the locking component 2 includes a drive mechanism 206, a cam 207, a rotating shaft 203, and a rotating arm 204. The rotating shaft 203 is symmetrically arranged on both sides of the stacker body 1. The cam 207 is located at the bottom of the rotating shaft 203 and cooperates with the annular guide rail 4. One end of the rotating arm 204 is fixedly installed on the rotating shaft 203, and the other end of the rotating arm 204 cooperates with the drive mechanism 206. The drive mechanism 206 drives the rotating arm 204 to rotate, the rotating arm 204 rotates, the rotating shaft 203 rotates, and the rotating shaft 203 rotates, causing the cam 207 to rotate. The end of the cam 207 is in close contact with the annular guide rail 4, thereby achieving the purpose of fixing the stacker body 1.

[0038] In this embodiment, as Figure 5 As shown, the driving mechanism 206 includes a driving cylinder 209 and a moving plate 2010. The piston rod of the driving cylinder 209 is fixedly installed on the moving plate 2010. There are strip holes 2013 on both sides of the center line of the moving plate 2010. A fixing column 205 is fixedly installed on the other end of the rotating arm 204. The fixing column 205 is slidably disposed in the strip hole 2013. The driving cylinder 209 is used to provide power for the movement of the moving plate 2010, ensuring the normal movement of the moving plate 2010, and at the same time ensuring the normal operation of the locking member 2.

[0039] In this embodiment, as Figure 2 As shown, a clearance hole 101 is provided at the bottom of the stacker crane body 1. A pad 102 is provided on the side of the clearance hole 101 away from the rotating shaft 203. The drive cylinder 209 is provided on the pad 102. The moving plate 2010 is provided in the clearance hole 101, and both ends of the moving plate 2010 extend to the outside of the clearance hole 101. The clearance hole 101 facilitates the installation of the drive cylinder 209 and the moving plate 2010, ensuring the normal operation of the drive cylinder 209 and the moving plate 2010.

[0040] In this embodiment, as Figure 4 , Figure 5As shown, the rotating arms 204 are symmetrically arranged on the upper and lower sides of the moving plate 2010. A sliding block 2011 is also provided in the strip hole 2013 on the moving plate 2010. The fixing post 205 on the other end of the rotating arms 204 on the upper and lower sides of the moving plate 2010 is rotatably mounted on the sliding block 2011. The arrangement of the strip hole 2013 and the sliding block 2011 can ensure the normal rotation of the rotating arms 204.

[0041] In this embodiment, as Figure 5 As shown, a sliding groove 2012 is also provided on the side wall of the strip hole 2013. The sliding block 2011 slides in conjunction with the sliding groove 2012. The sliding groove 2012 is provided to guide and limit the sliding block 2011, preventing the sliding block 2011 from falling out of the strip hole 2013 during movement, thus ensuring the normal operation of the sliding block 2011.

[0042] like Figure 4 As shown, several grooves 208 are also provided on one end of the cam 207. The grooves 208 are designed to increase the friction at the end of the cam 207 and prevent the end of the cam 207 from sliding between the annular guide rail 4 when the stacker crane body 1 is braked.

[0043] In this embodiment, as Figure 4 As shown, the locking component 2 also includes an upper support rod 202 and a lower support rod 201. The upper support rod 202 and the lower support rod 201 are arranged parallel to each other, one above the other, and are fixedly installed on the stacker crane body 1. The rotating shaft 203 is rotatably installed on the upper support rod 202 and the lower support rod 201. The upper support rod 202 and the lower support rod 201 are used to support the rotating shaft 203, ensuring the stability of the upper and lower ends of the rotating shaft 203 during operation, thereby improving the locking effect of the locking component 2.

[0044] In this embodiment, as Figure 6 As shown, the locking component 2 also includes a push-pull rod 2015, a locking plate 2017, and a guide plate 2014. The guide plate 2014 is disposed at the bottom of the stacker body 1. The locking plate 2017 is slidably mounted on the guide plate 2014. The push-pull rod 2015 is symmetrically disposed on both sides of the guide plate 2014, and one end of the push-pull rod 2015 is rotatably mounted on the other end of the cam 207. The locking plate 2017 can fill the gap between the guide plate 2014 and the top surface of the annular guide rail 4, thereby increasing the friction between the guide plate 2014 and the annular guide rail 4, and achieving the purpose of fixing the stacker body 1.

[0045] In this embodiment, as Figure 6As shown, a fixed shaft 2019 is fixedly installed on the other end of the push-pull rod 2015. The locking plate 2017 is slidably connected to the fixed shaft 2019. When the push-pull rod 2015 pulls the locking plate 2017 to move, the locking plate 2017 can move up and down along the fixed shaft 2019. When the top of the locking plate 2017 contacts the guide plate 2014 and the bottom of the locking plate 2017 contacts the annular guide rail 4, the purpose of fixing the stacker crane body 1 is achieved.

[0046] The locking plate 2017 is made of rubber, which ensures that the locking plate 2017 has a certain buffering effect after contacting the annular guide rail 4, thus ensuring the locking quality of the device.

[0047] In this embodiment, as Figure 6 As shown, the bottom of the guide plate 2014 is set as an inclined surface 2016. The inclined surface 2016 is set to be inclined downward along the direction closer to the rotating shaft 203. The guide plate 2014 is set to guide the locking plate 2017 and ensure that the locking plate 2017 is moved by the push-pull rod 2015.

[0048] like Figure 7 As shown, a guide groove 2020 is provided on the locking plate 2017. The guide groove 2020 is slidably engaged with the inclined surface 2016 of the guide plate 2014. The locking plate 2017 can move downward along the guide plate 2014 until the locking plate 2017 contacts the annular guide rail 4, thereby achieving the purpose of locking the stacker crane body 1.

[0049] In this embodiment, as Figure 6 As shown, a limit rod 2018 is provided at the edge of the inclined surface 2016, such as... Figure 7 As shown, a limiting groove 2021 is formed on the side wall of the guide groove 2020. The limiting groove 2021 is slidably engaged with the limiting rod 2018. The setting of the limiting rod 2018 and the limiting groove 2021 can prevent the locking plate 2017 from falling off the guide plate 2014 and ensure that the locking plate 2017 can always move along the guide plate 2014.

[0050] In this embodiment, as Figure 3 As shown, the anti-tilt mechanism 3 includes a horizontal plate 301, uprights 302 disposed at both ends of the horizontal plate 301, and guide wheels 303. The guide wheels 303 are disposed at the bottom of the uprights 302. The anti-tilt mechanism 3 can support the stacker body 1 and prevent the stacker body 1 from tilting during movement, thus ensuring the normal operation of the stacker body 1.

[0051] Its working process is as follows: When braking is required, the drive cylinder 209 is opened to move the moving plate 2010. The movement of the moving plate 2010 will cause one end of the rotating arm 204 to rotate around the rotating shaft 203 following the sliding block 2011 in the slot 2013. The rotation of the rotating arm 204 will cause the rotating shaft 203 to rotate. The rotation of the rotating shaft 203 will cause the cam 207 to rotate until the end of the cam 207 contacts the annular guide rail 4. During the rotation of cam 207, one end of push-pull rod 2015 is pulled to move, and the other end of push-pull rod 2015 will drive locking plate 2017 to move along guide plate 2014. As locking plate 2017 moves along guide plate 2014, locking plate 2017 moves towards annular guide rail 4 until locking plate 2017 is stuck between guide plate 2014 and annular guide rail 4, thereby achieving the purpose of locking and fixing stacker crane body 1.

[0052] The above content is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of this utility model, they should all fall within the protection scope of this utility model.
