Description

Technical Field

[0001] This utility model relates to the field of engine pallet storage technology, and specifically to an engine pallet transfer machine. Background Technology

[0002] The automobile engine, the heart of a car, provides power and determines its performance, fuel economy, stability, and environmental friendliness. The cylinder block and cylinder head are crucial components of the engine, and both are quite heavy. During the production and assembly of automobile engines, engine parts are placed on pallets and transported to the assembly station using AGV (Automated Guided Vehicle) transport vehicles. However, different engine models require different cylinder blocks and cylinder heads, each corresponding to a different type of pallet. Therefore, pallet transfer equipment is needed to retrieve, place, and recycle these different types of pallets within the warehouse.

[0003] Pallet transfer equipment requires lateral extension and retraction of its telescopic forks to move pallets laterally onto or remove them from shelves during the process of retrieving or storing pallets. To maximize the operating range of the telescopic forks, a large lateral extension distance is generally desirable. In existing technologies, telescopic fork structures utilize multi-layered structures to increase the fork's travel distance. For example, a patent document with authorization publication number CN218491391U, entitled "A Bidirectional Telescopic Fork Device with Conveying Function," describes a system with a fixed layer and a movable layer. A conveyor belt is installed on the movable layer. In use, goods are placed on the conveyor belt, and a moving drive mechanism drives the movable seat to move left and right, achieving the first stage of conveying. A conveyor drive assembly can then drive the conveyor rollers to rotate, moving the conveyor belt and achieving the second stage of conveying.

[0004] In the above-mentioned telescopic fork structure, although a large lateral conveying distance can be achieved through two-stage conveying, the structure is relatively complex and the manufacturing cost is high because an independent drive mechanism is required between the two layers. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an engine pallet transfer machine to solve the problems of complex structure and high manufacturing cost caused by the use of independent drive structure for each layer in the existing multi-layer telescopic fork structure of pallet transfer equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This application provides an engine pallet transfer machine, including a frame, and further comprising:

[0008] The slide base is slidably and vertically mounted on the frame.

[0009] A lifting drive device is fixedly installed on the slide base, and the lifting drive device is used to drive the slide base to move up and down along the frame;

[0010] A telescopic platform device includes a telescopic platform, a base plate, a track platform, a lateral drive assembly, and a pair of traction chains. The base plate is fixedly installed on the upper surface of the slide seat. The track platform is laterally slidably installed on the upper surface of the base plate. The lateral drive assembly is connected to the track platform. The telescopic platform is laterally slidably installed on the upper surface of the track platform. The track platform has a pair of parallel chain grooves arranged laterally. The pair of traction chains are respectively installed in the pair of chain grooves. One end of each pair of traction chains is fixedly installed at opposite ends of the base plate, and the other end of each pair of traction chains is fixedly installed at opposite ends of the telescopic platform.

[0011] Furthermore, rails are fixedly installed on the left and right sides of the bottom end face of the track platform, and the base plate is installed between the pair of rails. The left and right sides of the base plate are laterally slidably connected to the inner side of the rails through a first cam bearing follower. The bottom ends of the left and right sides of the telescopic platform are laterally slidably connected to the outer side of the rails through a second cam bearing follower.

[0012] Furthermore, the other end of the traction chain is fixedly mounted on the telescopic platform via a chain follower bracket. The chain follower bracket includes a mounting plate, a chain connecting block, and several claws. The mounting plate is fixedly mounted on the telescopic platform. The chain connecting block and the claws are fixedly disposed on the bottom surface of the mounting plate. The chain connecting block has a mounting hole. The chain pin at the outer edge of the other end of the traction chain is fixedly mounted in the mounting hole. Several claws are sequentially inserted into the insertion holes formed by adjacent pairs of chain pins on the traction chain.

[0013] Furthermore, the lateral drive assembly includes a first servo motor, a first rack, a first main gear, and a pair of driven gears. The first rack is laterally fixedly mounted on the bottom end face of the base plate. The first servo motor is fixedly mounted on the slide base. The first main gear is fixedly mounted on the output shaft of the first servo motor. The pair of driven gears are symmetrically arranged on opposite sides of the first main gear. The pair of driven gears are rotatably mounted on the slide base. The first main gear engages with the first rack for transmission through the pair of driven gears.

[0014] Furthermore, the lifting drive device includes a second servo motor, a second gear, and a second rack. The second servo motor is fixedly mounted on the slide base, the second gear is fixedly mounted on the output end of the second servo motor, and the second rack is vertically fixedly mounted on one side of the frame. The second gear meshes with the second rack.

[0015] Furthermore, it also includes a counterweight, which is disposed on the other side of the frame opposite to the slide base, and the upper end of the counterweight is fixedly connected to the upper end of the slide base by a chain.

[0016] Furthermore, it also includes a slide rail and a front and rear drive device. The slide rail is fixedly installed at the bottom end of the frame, and the bottom end of the frame and the slide rail form a sliding connection that moves in the front and rear direction. The front and rear drive device is connected to the bottom end of the frame.

[0017] Furthermore, it also includes a mounting base, the bottom end of which is slidably mounted on the slide rail via a slider, and the front and rear drive devices and the frame are fixedly mounted on the mounting base.

[0018] Furthermore, it also includes a pair of column support rods, one end of which is fixedly installed on the mounting base, and the other end of which is fixedly installed on the frame on the other side opposite to the slide base.

[0019] The beneficial effects of this utility model are as follows:

[0020] By employing the aforementioned engine pallet transfer machine, a track platform is laterally slidably mounted on the upper surface of the base, and a telescopic platform is laterally slidably mounted on the upper surface of the track platform. The telescopic platform and the track platform are connected by a traction chain. During the lateral movement of the track platform along the base, the track platform, via the traction chain on one side, drives the telescopic platform to move in the same direction. After the track platform reaches its maximum travel distance, due to the remaining movement margin of the traction chain relative to the track platform, the telescopic platform can continue to move forward along the track platform under inertia, achieving a greater lateral movement distance relative to the track platform. Meanwhile, when the other side... After the traction chain reaches its maximum travel, the other traction chain is fully taut, generating a pulling force in the opposite direction on the telescopic platform, restricting its further forward movement and ensuring its limit on the track platform. Simultaneously, the telescopic platform reaches its maximum travel. This structure utilizes a single power source to drive the track platform, and the traction chain between the telescopic platform and the track platform allows for further movement of the telescopic platform relative to the track platform. Its simple structure and low manufacturing cost solve the problems of complex structure and high manufacturing cost caused by the independent drive structure used in existing multi-layer telescopic fork structures on pallet transfer equipment.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0046] See appendix Figure 1 To be continued Figure 2As shown, this embodiment provides an engine pallet transfer machine 10, including a frame 100, a slide base 200, a lifting drive device, and a telescopic platform device 300. The slide base 200 is slidably installed on the front side of the frame 100, and the slide base 200 and the frame 100 form a vertical lifting and sliding connection. The lifting drive device is connected to the slide base 200 and is used to drive the slide base 200 to move up and down along the frame 100. The telescopic platform device 300 is installed on the slide base 200, and the engine pallet 20 is placed on the telescopic platform device 300. The telescopic platform device 300 drives the engine pallet 20 to move laterally left and right.

[0047] Combined with reference to the appendix Figure 4 To be continued Figure 6 As shown, in this embodiment, the telescopic platform device 300 includes a telescopic platform 301, a base plate 303, a track platform 302, a lateral drive assembly 304, and a pair of traction chains 305. The base plate 303 is fixedly installed on the upper surface of the slide base 200, and the track platform 302 is slidably installed on the base plate 303, forming a lateral sliding connection between the track platform 302 and the base plate 303 in the left-right direction. The lateral drive assembly 304 is connected to the track platform 302 and is used to drive the track platform 302 to slide laterally along the base plate 303. The telescopic platform 301 is arranged above the track platform 302, forming a lateral sliding connection between the telescopic platform 301 and the track platform 302 in the left-right direction. The pair of traction chains 305 are staggered, that is, one end of each pair of traction chains 305 is fixedly installed at opposite ends of the base plate 303, and the other end of each pair of traction chains 305 is fixedly installed at opposite ends of the telescopic platform 301.

[0048] See attached document Figure 4 and attached Figure 5 As shown, for ease of description, the end of the telescopic platform 301 and the track platform 302 located on the same side is referred to as the first end, and the other end located on the other side is referred to as the second end. For example, one end of a traction chain 305 is fixed at the first end of the base plate 303, and the other end of the traction chain 305 extends from the bottom end of the track platform 302 toward the second end and extends in the opposite direction from the top end of the track platform 302 to the first end of the telescopic platform 301, and is fixedly connected to the bottom surface of the first end of the telescopic platform 301. That is, both ends of the traction chain 305 are fixed on the same side, i.e., fixed at the first end on the same side. One end of another traction chain 305 is fixed to the second end of the base plate 303. The other end of the other traction chain 305 extends from the bottom end of the track platform 302 in the opposite direction to the first end and from the top end of the track platform 302 in the opposite direction to the second end of the telescopic platform 301, and is fixedly connected to the bottom surface of the second end of the telescopic platform 301. That is, both ends of the other traction chain 305 are fixed on the same side, that is, fixed at the second end on the same side.

[0049] See attached document Figure 4 and attached Figure 5 As shown, a pair of parallel chain grooves 3021 are provided on the upper end face of the track platform 302 in the transverse direction. The portion of the traction chain 305 that passes through the upper end face of the track platform 302 in the opposite direction is accommodated in the chain groove 3021. It can be understood that the chain groove 3021 is provided with a through hole that runs vertically through it, so that the traction chain 305 can pass through the through hole after extending along the bottom end face of the track platform 302 and then extend in the opposite direction along the upper end face of the track platform 302.

[0050] In this embodiment, a track platform 302 is laterally slidably mounted on the upper surface of the base, and a telescopic platform 301 is laterally slidably mounted on the upper surface of the track platform 302. The telescopic platform 301 and the track platform 302 are connected by a traction chain 305. During the lateral movement of the track platform 302 along the base by the lateral drive assembly 304, the track platform 302 will drive the telescopic platform 301 to move in the same direction via the traction chain 305 on one side. After the track platform 302 reaches its maximum travel distance, since the traction chain 305 still has a travel margin relative to the track platform 302 (the telescopic length of the traction chain 305 is greater than the maximum travel distance of the track platform 302), the telescopic platform 301, under the influence of inertia... The telescopic platform 301 can continue to move forward along the track platform 302, achieving a greater lateral movement distance relative to the track platform 302. When the traction chain 305 on the other side reaches its maximum travel, it is fully taut, generating a pulling force in the opposite direction on the telescopic platform 301, restricting the telescopic platform 301 from moving forward and ensuring that the telescopic platform 301 is limited on the track platform 302. At the same time, the telescopic platform 301 reaches its maximum travel. With the above structure, the track platform 302 is driven to move by a single power source, and the telescopic platform 301 can move further relative to the track platform 302 by using the traction chain 305 between the telescopic platform 301 and the track platform 302. The structure is simple and the manufacturing cost is low.

[0051] Continue to refer to the appendix Figure 4 and attached Figure 5As shown, the traction chain 305 is fixedly mounted on the telescopic platform 301 via a chain follower bracket 306. The chain follower bracket 306 includes a mounting plate 3061, a chain connecting block 3062, and several claws 3064. The mounting plate 3061 has bolt holes, and screws are installed in these holes to fix the mounting plate 3061 onto the telescopic platform 301. The chain connecting block 3062 and the claws 3064 are fixedly disposed on the bottom surface of the mounting plate 3061. In some embodiments, the mounting plate 3061, the chain connecting block 3062, and the claws 3064 are integrally formed. The chain connecting block 3062 has a mounting hole 3063, and the chain pin at the outer edge of the other end of the traction chain 305 is fixedly installed in the mounting hole 3063. Several claws 3064 are sequentially inserted into the insertion holes formed by adjacent pairs of chain pins on the traction chain 305 (see attached diagram). Figure 7 and attached Figure 8 (As shown).

[0052] See attached document Figure 7 and attached Figure 8 As shown, by providing mounting holes 3063 on the chain connecting block 3062, the chain pin at one end of the traction chain 305 can be inserted into and fixed in the mounting holes 3063. At the same time, several claws 3064 are sequentially inserted into the insertion holes of the traction chain 305. The claws 3064 ensure that the traction chain 305 is in a straightened and stretched state at the connection point with the chain connecting block 3062, making it less likely for the chain to fold or tangle.

[0053] See attached document Figure 4 Appendix Figure 6 and appendix Figure 10 As shown, in this embodiment, the lateral drive assembly 304 includes a first servo motor 3041, a first rack 3044, a first main gear 3042, and a pair of driven gears 3043. The first rack 3044 is horizontally fixedly installed on the bottom end face of the base plate 303, and a pair of traction chains 305 are symmetrically arranged on the left and right sides of the first rack 3044.

[0054] The first servo motor 3041 is fixedly mounted on the slide base 200, the first main gear 3042 is fixedly mounted on the output shaft of the first servo motor 3041, a pair of driven gears 3043 are symmetrically arranged on opposite sides of the first main gear 3042, and the pair of driven gears 3043 are rotatably mounted on the slide base 200. The first main gear 3042 is driven by meshing with the first rack 3044 through the pair of driven gears 3043.

[0055] The first servo motor 3041 rotates in the forward or reverse direction, driving the first main gear 3042 to rotate clockwise or counterclockwise. The rotating first main gear 3042 then drives the first rack 3044 to move laterally through a pair of driven gears 3043, thereby driving the track platform 302 to move laterally back and forth.

[0056] See attached document Figure 4 and attached Figure 9 As shown, in this embodiment, rails 307 are fixedly installed on the left and right sides of the bottom end face of the track platform 302, and a base plate 303 is installed between the pair of rails 307. The left and right sides of the base plate 303 are laterally slidably connected to the inner side of the rails 307 through a first cam bearing follower 308. The bottom ends of the left and right sides of the telescopic platform 301 are laterally slidably connected to the outer side of the rails 307 through a second cam bearing follower 309. By arranging the telescopic platform 301, the track platform 302, and the base plate 303 sequentially from top to bottom, i.e., the telescopic platform 301 is installed on the outer side of the track platform 302 and the base plate 303 is installed on the inner side of the track platform 302, the internal space of the track platform 302 can be effectively utilized.

[0057] See attached document Figure 2 As shown, in this embodiment, the lifting drive device includes a second servo motor 120, a second gear, and a second rack 110. The second servo motor 120 is fixedly installed on the slide base 200, the second gear is fixedly installed on the output end of the second servo motor 120, and the second rack 110 is vertically fixedly installed on one side of the frame 100. The second gear meshes with the second rack 110.

[0058] When the second servo motor 120 rotates in the forward or reverse direction, the output shaft of the second servo motor 120 will synchronously drive the second gear to rotate in the forward or reverse direction. The rotating second gear will move up or down along the second rack 110. Since the second rack 110 is fixed on the frame 100, the second gear will rise or fall relative to the frame 100. Consequently, the slide base 200 will rise or fall along the frame 100. The slide base 200 will synchronously drive the telescopic platform device 300 installed on it to move up and down. The pallet placed on the telescopic platform device 300 will move up and down synchronously so that it can be moved to the pallet rack at different heights.

[0059] See attached document Figure 3As shown, a counterweight 500 is also provided on the frame 100. The counterweight 500 is located on the opposite side of the frame 100 relative to the slide base 200, and the upper end of the counterweight 500 is fixedly connected to the upper end of the slide base 200 via a chain 700. By placing the counterweight 500 and the slide base 200 on opposite sides of the frame 100, the stability of the pallet placed on the slide base 200 during the lifting process can be improved.

[0060] See attached document Figure 1 To be continued Figure 3 As shown, a slide rail 400 is also provided at the bottom of the frame 100, and a mounting base 600 is fixedly installed at the bottom of the frame 100. The bottom surface of the mounting base 600 is slidably mounted on the slide rail 400 through a slider. The slide rail 400 is arranged in a front-to-back manner, so that the frame 100 can slide on the slide rail 400 through the mounting base 600 to move from one end of the pallet rack to the other end of the pallet rack.

[0061] The frame 100 moves back and forth by means of a front and rear drive device 800. The front and rear drive device 800 can be a servo motor and a gear. A rack is arranged on the inner side of one side of the slide rail 400. The servo motor drives the gear to rotate. The rotating gear meshes with the rack fixed on the inner side of one side of the slide rail 400 to realize the back and forth movement of the frame 100 along the slide rail 400.

[0062] See attached document Figure 3 As shown, a pair of column support rods 900 are provided between the frame 100 and the mounting base 600. One end of the pair of column support rods 900 is fixedly installed on the mounting base 600, and the other end of the pair of column support rods is fixedly installed on the side of the frame 100 opposite to the slide base 200. By installing column support rods 900 at the bottom end of the frame 100 opposite to the slide base 200, the stability of the frame 100 when the slide base 200 moves up and down along the frame 100 can be improved, preventing the frame 100 from tilting to one side of the slide base 200.

[0063] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
