Description
Technical Field
[0001] This utility model belongs to the technical field of warehousing and handling equipment, and particularly relates to a warehousing stacker crane for logistics handling. Background Technology
[0002] Stacker cranes are key equipment in automated warehouses for storing, retrieving, handling, and stacking goods. They are mainly used for picking up and placing goods in high-rise rack aisles and are characterized by fast handling speed and high storage and retrieval efficiency.
[0003] When using a stacker crane, goods are usually placed on a pallet first, and then the pallet is lifted by the stacker crane's forks to pick up and put away the goods. However, when traditional forks lift goods, they are prone to falling and damaging the goods. Therefore, baffles are installed on both sides of the forks to clamp the goods and prevent them from tipping over. However, when dealing with irregularly shaped goods, the contact points between the traditional baffles and the goods are unevenly distributed and cannot effectively stabilize the goods. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art that irregularly shaped goods are not easily clamped by the baffle and are prone to tipping over by setting several clamping members on the clamping surface and elastically connecting the clamping members to the clamping plate. The clamping members can fit against the surface of irregularly shaped goods through the action of compression springs.
[0005] The specific technical solution of this utility model is as follows:
[0006] A warehouse stacker crane for logistics handling includes a gantry frame and a slide rail, with the gantry frame slidably connected to the slide rail. The gantry frame includes two side columns and a top crossbeam. The two side columns are slidably connected to a fork extension mechanism. The gantry frame is equipped with a lifting mechanism, which controls the up and down movement of the fork extension mechanism. The fork extension mechanism includes a front upright plate, with two forks slidably connected laterally to the lower part of the front upright plate. Two clamping plates are slidably connected laterally to the front surface of the front upright plate. The clamping plates have clamping surfaces that contact the goods. The clamping surfaces of the two clamping plates are arranged opposite to each other. The clamping surfaces are arrayed with several sliding holes. The clamping plates are equipped with several clamping elements, which slide in conjunction with the sliding holes. A compression spring is fixedly connected to the end of each clamping element. A limiting element is provided at the rear of each clamping element. An annular locking element is provided at the opening of the sliding hole to prevent the clamping element from falling out of the sliding hole.
[0007] Furthermore, a top plate is slidably connected to the top of the front upright, and a bottom plate is slidably connected to the bottom of the front upright. The two ends of the top plate are slidably connected to the two side columns, and the two ends of the bottom plate are slidably connected to the two side columns.
[0008] Furthermore, a lifting motor is installed on the upper part of the crossbeam. The drive shaft of the lifting motor is connected to a drum, and a cable is wound on the drum. One end of the cable is fixedly connected to the drum, and the other end is fixedly connected to the top plate.
[0009] Furthermore, a telescopic push rod motor is installed on the lower surface of the top plate, and the push rod of the telescopic push rod motor is fixedly connected to the rear facade of the front panel.
[0010] Furthermore, a rack is fixed laterally on the rear side of the clamping plate, and the teeth of the racks on both sides of the clamping plate are arranged opposite each other. A clamping motor is installed on the rear side of the front plate, and a gear is connected to the front end of the motor shaft. The motor shaft of the clamping motor passes through the front plate, and the gear is located at the front of the front plate. The gear meshes with the racks on both sides of the clamping plate respectively.
[0011] Furthermore, the rear side of the clamping plate is provided with a clearance slot, and the rack is located in the clearance slot. The width of the clearance slot is not less than the width of the rack.
[0012] Furthermore, the lower surface of the front section of the forks is sloped.
[0013] Furthermore, a load-bearing slide is provided at the rear of the forks, and a linear through groove is provided horizontally below the front upright plate. The top and bottom of the load-bearing slide are respectively provided with slots, which are adapted to the groove walls of the linear through groove.
[0014] Furthermore, the slide rail has a wide-bottomed I-shaped cross-section and includes a rail head, a rail web, and a rail bottom. The rail head and rail bottom are connected by the rail web. The gantry frame is equipped with a base, and the lower surface of the base is provided with a track groove. The track groove includes a horizontal groove for the rail head and a vertical groove for the rail web.
[0015] Furthermore, several drive rollers and several driven rollers are rotatably connected inside the transverse groove. The drive rollers are in contact with the upper surface of the rail head and are equipped with a moving motor. The driven rollers are in contact with the lower surface of the rail head.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In use, adjust the distance between the two forks to a suitable position, start the telescopic push rod motor to push the front upright plate forward, place the forks at the bottom of the pallet, and then start the clamping motor to bring the two clamping plates closer together and make the top of the clamping parts fit against the surface of the goods. Through the deformation of the compression spring, the clamping parts on both sides of the goods can keep in contact with different shaped parts of the goods surface. The contact points between irregularly shaped goods and the clamping plates increase, increasing the force-bearing area, achieving the purpose of stabilizing irregularly shaped goods, improving safety in the logistics handling process, and reducing the accident rate.

[0030] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0031] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0032] See Figures 1 to 6This embodiment discloses a warehouse stacker crane for logistics handling, including a gantry frame 1 and a slide rail 5. The slide rail 5 is fixed to the ground by expansion bolts, and the gantry frame 1 is slidably connected to the slide rail 5. The gantry frame 1 includes two side columns 11 and a top crossbeam 12. The slide rail 5, columns 11, and crossbeam 12 are made of steel. The two ends of the crossbeam 12 are welded to the columns 11 respectively. The two side columns 11 are slidably connected to a fork extension mechanism. The gantry frame 1 is equipped with a lifting mechanism, which controls the up and down movement of the fork extension mechanism. The mechanism includes a front upright plate 2, with two forks 21 laterally slidably connected to its lower part. Lateral grooves are provided on the upper and lower parts of the front upright plate 2, and sliding elements adapted to the lateral grooves are provided on the upper and lower parts of the rear upright plate 22. The front upright plate 2 achieves lateral sliding connection with the two clamping plates 22 through the sliding engagement of the lateral grooves and sliding elements. Further optimization is possible by defining the lateral grooves as T-shaped grooves to prevent the sliding elements from falling out. The clamping plates 22 have clamping surfaces 2 that contact the goods. 21. The clamping surfaces 221 of the two clamping plates 22 are arranged opposite each other. The clamping surfaces 221 have an array of sliding holes 222. The clamping plates 22 are provided with a number of clamping members 223. The clamping members 223 slide with the sliding holes 222. A compression spring 224 is fixedly connected to the end of the clamping member 223. The clamping member 223 and the compression spring 224 are made of metal, and stainless steel can be further optimized. The end of the clamping member 223 is fixedly connected to the compression spring 224 by welding. The deformation of the compression spring 224 causes... The clamping parts 223 on both sides can fit into different shaped parts on both sides of the cargo, so as to stabilize the cargo with irregular shape. The clamping part 223 is provided with a limiting part 2231 at the rear. The opening of the sliding hole 222 is provided with an annular locking part 2221. The inner diameter of the annular locking part 2221 is smaller than the outer diameter of the limiting part 2231 and larger than the outer diameter of the clamping part 223. This makes it convenient for the clamping part 223 to move in the sliding hole 222 through the deformation of the compression spring 224, and also prevents the clamping part 223 from falling out of the sliding hole 222.
[0033] A top plate 23 is slidably connected to the top of the front upright plate 2. Two vertical grooves are provided on the lower surface of the top plate 23. Two sliders, matching the vertical grooves, are provided on the top of the front upright plate 2. The front upright plate 2 achieves a slidable connection with the top plate 23 through the sliding engagement of the sliders and the vertical grooves. A bottom plate 24 is slidably connected to the bottom of the front upright plate 2. Two vertical grooves are provided on the upper surface of the bottom plate 24. Two sliders, matching the vertical grooves, are provided on the bottom of the front upright plate 2. The front upright plate 2 achieves a slidable connection with the bottom plate 24 through the sliding engagement of the sliders and the vertical grooves. Further optimization could be achieved by designing the vertical grooves as T-shaped grooves to prevent… The slider detaches from the vertical groove. The top plate 23 is slidably connected to the two side columns 11 at both ends, and the bottom plate 24 is slidably connected to the two side columns 11 at both ends. The top plate 23 and the bottom plate 24 are respectively provided with limiting grooves. The two side columns 11 are respectively provided with limiting strips that are adapted to the limiting grooves at one end. Through the sliding cooperation of the limiting grooves and limiting strips, the top plate 23 and the bottom plate 24 are slidably connected to the columns 11. It can be further optimized that the limiting groove is a T-shaped groove, which can prevent the limiting strip from slipping out of the limiting groove during the sliding process, so that the vertical displacement of the fork extension mechanism is more stable.
[0034] A lifting motor 121 is installed on the upper part of the crossbeam 12. The drive shaft of the lifting motor 121 is connected to a drum 1211. A cable 1212 is wound around the drum 1211. One end of the cable 1212 is fixedly connected to the drum 1211, and the other end is fixedly connected to the top plate 23 by a retaining ring. When the lifting motor 121 is started, the lifting motor 121 outputs rotational power to drive the drum 1211 to rotate, winding the cable 1212 around the drum 1211. Shortening the cable 1212 causes the fork extension mechanism to move upward. Conversely, the lifting motor 121 drives the drum 1211 to reverse and lengthen the cable 1212, causing the fork extension mechanism to move downward.
[0035] A telescopic push rod motor 4 is installed on the lower surface of the top plate 23. The push rod of the telescopic push rod motor 4 is fixedly connected to the rear surface of the front upright plate 2. When the telescopic push rod motor 4 is started, the front upright plate 2 is pushed forward, and the forks 21 are placed at the bottom of the pallet. Conversely, the telescopic push rod motor 4 pulls the front upright plate 2 back, and the forks 21 are retracted from the bottom of the pallet.
[0036] A rack 225 is horizontally fixed on the rear side of the clamping plate 22. The clamping plate 22 and the rack 225 are made of metal and are fixedly connected together by welding. The teeth of the rack 225 on the two clamping plates 22 are arranged opposite each other. A clamping motor 3 is installed on the rear side of the front plate 2. A gear 25 is connected to the front end of the motor shaft. The front plate 2 has a shaft hole. The motor shaft of the clamping motor 3 passes through the shaft hole, so that the gear 25 is located at the front of the front plate 2. The gear 25 meshes with the rack 225 on the two clamping plates 22 respectively. When the clamping motor 3 is started, the two clamping plates 22 are brought closer to each other through the meshing of the gear 25 with the upper and lower racks 225, and the top of the clamping member 223 is in contact with the surface of the goods. Conversely, when the clamping motor 3 reverses, the two clamping plates 22 move away from each other and the goods are released.
[0037] The rear side of the clamping plate 22 is provided with a clearance slot 226, and the rack 225 is located in the clearance slot 226. The width of the clearance slot 226 is not less than the width of the rack 225. The clearance slot 226 ensures that the rack 225 will not be blocked by the clamping plate 22 when it moves, thus extending the travel of the rack 225 and enabling the two clamping plates 22 to clamp smaller goods, thereby improving practicality.
[0038] The lower surface of the front section of the fork 21 is sloped, and the sloped design at the bottom of the fork 21 is a guide design to facilitate insertion into the bottom of the pallet. This design, by setting a slightly inclined lower surface at the front end of the horizontal section of the fork 21, can effectively reduce the resistance when inserting into the bottom of the pallet, allowing the fork 21 to enter the bottom of the pallet more smoothly and improving picking efficiency.
[0039] The fork 21 is provided with a load-bearing slide 211 at the rear. A linear through groove 26 is provided horizontally below the front upright plate 2. The top and bottom of the load-bearing slide 211 are respectively provided with a slot 2111. The slot 2111 is adapted to the groove wall of the linear through groove 26. The groove wall of the linear through groove 26 is inserted into the slot 2111. This not only realizes the sliding connection between the fork 21 and the front upright plate 2, but also ensures that when the fork 21 lifts the goods, the load-bearing slide 211 will not fall out of the linear through groove 26 due to gravity, thus preventing an accident.
[0040] The slide rail 5 has a wide-bottom I-shaped cross section. The wide-bottom rail base 53 increases the contact area with the ground and improves the stability of the gantry 1 running on the slide rail 5. The slide rail 5 includes a rail head 51, a rail waist 52 and a rail base 53. The rail head 51 and the rail base 53 are connected by the rail waist 52. The gantry 1 is provided with a base 13. The lower surface of the base 13 is provided with a track groove 131. The track groove 131 includes a horizontal groove 1311 that matches the rail head 51 and a vertical groove 1312 that matches the rail waist 52.
[0041] Several drive rollers 132 and several driven rollers 133 are rotatably connected inside the transverse groove 1311. The drive rollers 132 are in contact with the upper surface of the rail head 51. The drive rollers 132 are equipped with a moving motor 134, which is located outside the base 13. The base 13 has a connection hole, through which the output shaft of the moving motor 134 passes and is fixedly connected to the axle of the drive rollers 132. When the moving motor 134 is started, the drive rollers 132 are driven to roll along the length of the slide rail 5 on the upper surface of the rail head 51, thereby realizing the movement of the gantry 1 on the slide rail 5. The driven rollers 133 are in contact with the lower surface of the rail head 51. When the gantry 1 slides on the slide rail 5, the driven rollers 133 can reduce the friction between the base 13 and the slide rail 5, thereby reducing energy loss and equipment wear.
[0042] In this embodiment, the start / stop and forward / reverse control of the lifting motor 121, the moving motor 134, the clamping motor 3, and the telescopic push rod motor 4, as well as their connection to the external power supply, can adopt existing solutions in the prior art.
[0043] In use, adjust the distance between the two forks 21 to a suitable position, start the telescopic push rod motor 4 to push the front upright plate 2 forward, place the forks 21 at the bottom of the pallet, and then start the clamping motor 3 to bring the two clamping plates 22 closer together and make the top of the clamping parts 223 fit against the surface of the goods. Through the deformation of the compression spring 224, the clamping parts 223 on both sides can fit against different shaped parts on both sides of the goods, so as to stabilize the irregularly shaped goods. Then start the moving motor 134 to move the goods to the designated shelf, start the lifting motor 121 to lift the fork extension mechanism to the designated position on the shelf, and send the goods onto the shelf through the telescopic push rod motor 4. The clamping motor 3 rotates in the opposite direction to move the two clamping plates 22 away from each other and release the goods. Then the telescopic push rod motor 4 drives the front upright plate 2 to move backward and pull the forks 21 out from the bottom of the pallet, completing one process of moving goods onto the shelf.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
