Description

Technical Field

[0001] The invention relates to the technical field of material transfer, in particular to a material loading trolley. Background Art

[0002] Products such as battery packs and molds usually weigh hundreds of pounds. In order to facilitate transportation, carts are used in the transfer process to transfer them to the corresponding production line.

[0003] Due to the heavy weight of the product, in order to prevent the product from sliding off during the transfer process, a blocking block is installed on the cart to prevent the product from sliding out. When the front end of the cart is docked with the front end of the production line, the blocking block is generally deflected to one side by a cylinder or motor to make way for the transfer of the product so that the product can be pushed from the cart to the production line. It has the following defects: first, the cylinder or motor controls the deflection of the blocking block, which requires electrical system control and is costly; second, after the cart is docked with the production line, the cart and the production line are not locked together, so the cart is easy to move during the transfer process, affecting the transfer of the product. The product is easy to slide down due to the movement of the cart during the transfer process, injuring the operator. Summary of the invention

[0006] Furthermore, at least one hinge support is provided in the middle part of the top of the vehicle body, and a rotating shaft is rotatably connected to the hinge support. The conveying assembly includes a carrying platform and a plurality of rollers. The middle part of the bottom of the carrying platform is fixedly connected to the rotating shaft through a fixed block, and a row of rollers for conveying products is provided on each side of the carrying platform.

[0007] Furthermore, the locking mechanism includes a rotating shaft and a handle. The rotating shaft is rotatably connected to the carrying platform and passes through from the front end of the carrying platform to the rear end of the carrying platform. One end of the rotating shaft is connected to the locking piece located at the front end of the carrying platform, and the other end is connected to the handle.

[0008] Furthermore, a first fixed plate is provided on one end of the carrying platform close to the production line docking unit, the rocker arm is rotatably connected to the side of the first fixed plate, the rotating shaft is rotatably connected to the first fixed plate, and a contact rod is provided at one end of the rocker arm that naturally hangs down.

[0009] Furthermore, one end of the swing rod away from the contact rod is protruded toward the product incoming direction to form a blocking portion, and the upper edge of the first fixing plate has an avoidance groove for avoiding the blocking portion.

[0010] Furthermore, the production line docking unit includes a support seat, a second fixed plate and a docking block, the second fixed plate is vertically fixed on the support seat, the docking blocks are respectively arranged on both sides of the second fixed plate and are perpendicular to the second fixed plate, the locking pin is fixed on the side of the second fixed plate close to the locking member, and the top block is fixedly installed on the second fixed plate and corresponds to the contact rod.

[0012] Furthermore, pressure wheels are arranged on both sides of the outer side of the conveying component, and the pressure wheels are rotatably connected to the conveying component and are eccentrically arranged.

[0013] Furthermore, the locking member includes a main body, a limiting portion and a locking portion, the limiting portion and the locking portion are parallel to each other and are integrally connected to the same side of the main body, the main body is rotatably connected to the first fixed plate, a limiting groove for limiting the anti-detachment portion is formed between the limiting portion and the locking portion, the bottom of the locking portion has the locking groove, and the limiting portion extends to the rotation path after the rocker arm touches the top block.

[0014] Furthermore, at least one buffer is provided on one end of the conveying assembly close to the production line docking unit.

[0015] Compared with the prior art, the beneficial effects are: The production line docking unit of the present invention is installed at the front end of the production line for positioning and docking with the vehicle body. The conveying assembly is used to convey the product to the production line. Since the rear end of the product has a large deadweight, after the product is placed on the conveying assembly, the conveying assembly will tilt toward the rear end of the vehicle body. The rear limit mechanism at the rear end of the conveying assembly can block and limit the rear end of the product, and the front limit mechanism at the front end of the conveying assembly can block and limit the front end of the product, so that the product will not move forward and backward during the movement of the trolley. In the natural state, one end of the swing arm is tilted upward to form a blockage at the front end of the product, and the other end is drooping. When the front end of the vehicle body is docked with the production line docking unit, the top block on the production line docking unit will gradually approach the rocker arm at the front end of the conveying component, and the top block and the rocker arm will cooperate at an inclined surface to gradually lift the drooping end of the product upward, while the originally upturned end of the rocker arm will gradually rotate downward, thereby contacting the product on the conveying component and pressing the locking piece downward, so that the locking piece also rotates synchronously. During the rotation of the locking piece, the locking groove will engage with the locking pin on the product docking unit, thereby locking the vehicle body and the production line together, ensuring that the product body will not move at will during the transportation process and the product can be safely and smoothly transferred to the production line.

[0016] The lock between the vehicle body and the production line can be released by rotating the locking piece in the opposite direction. As the vehicle body gradually moves away from the production line docking unit, the swing arm will return to its original position, thus blocking the front end of the product when the product is transported again.

[0017] The present invention does not require a complex electrical control mechanism to control the swing of the rocker arm. By utilizing the deviation of the center of gravity of the rocker arm from the rotation center, the rocker arm can block the products on the trolley. The top block and the inclined surface of the rocker arm cooperate to control the deflection of the rocker arm. A mechanical unlocking design is adopted to quickly release the blocking limit of the rocker arm on the product. The structure is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Figure 1-Figure 2As shown, a preferred embodiment of the present invention proposes a loading trolley, which mainly includes a body 1, a conveying assembly 2, a production line docking unit 3, a locking mechanism 4, a front limit mechanism 6, and a rear limit mechanism 5. The body 1 adopts a frame structure. Four universal wheels 8 are installed at the bottom of the body 1, and a handle 7 is welded at the rear end of the body 1 to facilitate pushing the trolley. The conveying assembly 2 is installed on the top of the body 1 for conveying products.

[0022] Specifically, refer to Figure 2 , Figure 3 The conveying assembly 2 is mainly composed of a carrying platform 21 and a plurality of rollers 22, wherein two hinge supports 23 are provided in the middle of the top of the vehicle body 1, and the two hinge supports 23 are respectively located near the left and right sides of the vehicle body 1, and a rotating shaft (not shown in the figure) is installed on each hinge support 23. Correspondingly, two mounting holes are provided on the carrying platform 21, and the two hinge supports 23 pass through the mounting holes. The two ends of the rotating shaft are fixedly connected to the fixing block 24, and the fixing block 24 is fixed to the carrying platform 21 by screws, so that the carrying platform 21 can be deflected forward and backward relative to the vehicle body 1 by the rotating shaft. The plurality of rollers 22 are divided into two rows, and the two rows of rollers 22 are respectively installed on both sides of the inner side of the carrying platform 21 and are rotatably connected to the carrying platform 21. The rollers 22 are placed vertically to facilitate the conveying of products.

[0023] The front limiting mechanism 6 is installed at the front end of the carrying platform 21, and the rear limiting mechanism 5 is installed at the rear end of the carrying platform 21, which are respectively used to limit the front and rear ends of the product to prevent the product from sliding off the trolley.

[0024] A first fixed plate 9 is vertically fixed at the rear end of the carrying platform 21 (i.e., the end away from the handle 7). The front limiting mechanism 6 is mainly composed of a first rocker arm 61 and a top block 62. The first rocker arm 61 is rotatably connected to the side of the first fixed plate 9 through a rotating shaft, close to the end of the first fixed plate 9.

[0025] like Figure 1 As shown, the production line docking unit 3 is installed at the front end of the production line for docking with the trolley.

[0026] refer to Figure 4The production line docking unit 3 is mainly composed of a support seat 31, a second fixed plate 32 and a docking block 33, wherein the second fixed plate 32 is vertically fixedly installed on the support seat 31 and is parallel to the first fixed plate 9. A front limit mechanism 6 is also installed on the second fixed plate 32, which is composed of a second swing rod 63 and a top block 62. Similarly, the second swing rod 63 is rotatably connected to the side of the second fixed plate 32 through a rotating shaft, close to the end of the second fixed plate 32. The positions of the two top blocks 62 correspond to the first swing rod 61 and the second swing rod 63, respectively. The first swing rod 61 and the second swing rod 63 are symmetrically arranged, and the two top blocks 62 are also symmetrically arranged.

[0027] The structure of the first swing rod 61 is the same as that of the second swing rod 63. Figure 5 , Figure 8 One end of the swing rod is convexly formed with a blocking portion 611, and the other end is fixedly mounted with a contact rod 64, which is perpendicular to the swing rod, so that the overall shape of the swing rod is "L" shaped. The rotating shaft is rotatably connected to the end of the swing rod close to the blocking portion 611, so that the center of gravity of the swing rod is close to the end of the contact rod 64. Therefore, in the natural state of the swing rod, since the end of the swing rod with the contact rod 64 is heavier, the end of the swing rod with the contact rod 64 swings downward, and the end of the swing rod with the blocking portion 611 swings upward, so that the swing rod can play a blocking role on the product.

[0028] In this embodiment, the first fixing plate 9 can be fixedly mounted on the cart, so the first swing arm 61 can block the products on the cart to prevent the products from slipping out of the cart. The second fixing plate 32 can be mounted at the front end of the production line, so the second swing arm 63 can block the products on the production line to prevent the products from slipping out of the production line.

[0029] The blocking portion 611 at the upper end of the swing arm will play a role in positioning and blocking the product. An escape groove (not marked in the figure) is provided at the corresponding position of the upper edge of the first fixed plate 9 and the second fixed plate 32. The escape groove is used to avoid the blocking portion 611. When the upper end of the first swing arm 61 (i.e., the end with the blocking portion 611) swings downward, the blocking portion 611 can be accommodated in the escape groove, thereby removing the blocking of the product on the cart. Similarly, the blocking portion 611 on the second swing arm 63 can also be accommodated in the escape groove on the upper edge of the second fixed plate 32, so that the product on the cart can be transferred to the production line.

[0030] The avoidance groove can also play a limiting role to prevent the end of the swing rod having the blocking portion 611 from swinging downward excessively.

[0031] refer to Figure 5, each top block 62 has an inclined surface at its front end, and the height of the top block 62 is appropriately higher than the height of the contact rod 64. When the first fixing plate 9 approaches the second fixing plate 32, the front end of the contact rod 64 will gradually contact the inclined surface on the top block 62 and slide relatively along the inclined surface. In this process, the contact rod 64 will gradually rise upward, so that the end of the swing arm with the contact rod 64 gradually rises upward, and the end of the contact rod 64 with the blocking portion 611 gradually falls downward, thereby releasing the blocking limit.

[0032] In this embodiment, in order to facilitate the contact rod 64 to better contact with the top block 62, the front end of the contact rod 64 also has an inclined surface that matches the inclined surface on the top block 62 to reduce resistance.

[0033] In other technical solutions, only the front end of the contact rod 64 may be provided with an inclined surface, and the top block 62 may not be provided with an inclined surface. Alternatively, the top block 62 may be provided with an inclined surface, and the contact rod 64 may not be provided with an inclined surface.

[0034] like Figure 6 , Figure 7 In order to limit the rotation angle of the first swing rod 61 and the second swing rod 63, two positioning pins 16 are provided on the first fixing plate 9 and the second fixing plate 32, below the first swing rod 61 and the second swing rod 63. The two positioning pins 16 are respectively located on the forward and reverse rotation paths of the swing rod to limit the rotation angle of the swing rod, and prevent the swing rod from rotating several circles due to excessive impact of the top block 62 on the contact rod 64. Due to the presence of the positioning pins 16, the deflection of the swing rod generally does not exceed 90°.

[0035] like Figure 1 As shown, the locking mechanism is mainly composed of a locking member 41 and a locking pin 42, wherein the locking member 41 is rotatably connected to the middle area of ​​the side of the first fixing plate 9 through a rotating shaft, and correspondingly, the locking pin 42 is fixedly installed in the middle area of ​​the side of the second fixing plate 32. In other technical solutions, the installation positions of the locking member 41 and the locking pin 42 can also be interchanged.

[0036] like Fig.10 As shown, the locking member 41 is mainly composed of a main body 411, a limiting portion 412 and a locking portion 413. The limiting portion 412 and the locking portion 413 are parallel and integrally connected to one side of the main body, so that the locking member 41 is in an "n" shape. A limiting groove 4101 is formed between the limiting portion 412 and the locking portion 413, and a locking groove 4102 is provided at the lower edge of the locking portion 413.

[0037] The locking pin 42 is cylindrical, and when the locking member 41 is rotated, the locking groove 4102 on the locking member 41 will engage with the locking pin 42, so that the left and right locking of the cart and the production line can be completed. In order to prevent the cart from moving forward and backward, a disc 421 is provided at the front end of the locking pin 42, and the diameter of the disc 421 is larger than the diameter of the locking pin 42. Therefore, when the locking member 41 is rotated, the disc 421 will be embedded in the limiting groove 4101, and the locking pin 42 will engage with the locking groove 4102. The disc 421 can prevent the locking pin 42 from being separated from the locking groove 4102, so that the front and back locking of the cart and the production line can be completed, and the cart will not move left and right and forward and backward.

[0038] The length of the limiting portion 412 on the locking member 41 is slightly longer than the length of the locking portion 413, and extends to the bottom of the first swing rod 61, and is located on the rotation path of the end of the first swing rod 61 with the blocking portion 611. When the blocking limit of the first swing rod 61 is released, the front end of the limiting portion 412 of the locking member 41 will extend to the rotation path of the first swing rod 61. During the rotation process, the first swing rod 61 will press the locking member 41 downward, so that the locking member 41 rotates synchronously, and the rotation direction is opposite to the rotation direction of the first swing rod 61. During the rotation process of the locking member 41, the locking groove 4102 will be engaged with the locking pin 42 on the second fixing plate 32 to lock the trolley and the production line.

[0039] The width of the lock slot 4102 is slightly larger than the thickness of the disc 421 at the front end of the lock pin 42, so that the cart has a margin for moving forward and backward. When unlocking, the cart moves back a little, and at this time, the end of the first swing rod 61 with the blocking portion 611 gradually swings upward, so that the locking member 4 can be rotated to disengage from the lock pin 42, and the unlocking is completed.

[0040] In this embodiment, the locking member 41 is located at the lower right of the first swing rod 61. Preferably, when the first swing rod 61 rotates clockwise, one end of the first swing rod 61 with the blocking portion 611 can press down the limiting portion 412 of the locking member 41, so that the locking member 41 rotates counterclockwise, thereby completing the locking with the locking pin 42. In other technical solutions, the locking member 41 can also be set at the upper left of the first swing rod 61. When the first swing rod 61 rotates clockwise, one end of the first swing rod with the contact rod 64 swings upward, thereby pushing the locking member 41 upward, so that the locking member 41 rotates counterclockwise, thereby completing the locking with the locking pin 42.

[0041] like Figure 1 , Fig. 9As shown, in order to control the rotation of the locking member 41, a rotating shaft 14 is also provided on the carrying platform 21, and the rotating shaft 14 runs from the front end of the carrying platform 21 to the rear end of the carrying platform 21. A bearing seat 18 is provided at the rear end of the carrying platform 21, and both ends of the rotating shaft 14 are rotatably connected to the bearing seat 18 and the first fixing plate 9 through bearings. The locking member 41 is fixedly connected to the end of the rotating shaft 14, and when the rotating shaft 14 rotates, it can drive the locking member 41 to rotate, so as to control the locking and unlocking of the locking member 41 and the locking pin 42.

[0042] A limit fixing member 19 is installed at the other end of the rotating shaft 14 (i.e., the end away from the locking member 41). A handle 20 is provided on the limit fixing member 19. By holding the handle 20, the limit fixing member 19 is controlled to rotate together with the rotating shaft 14, thereby driving the locking member 41 to rotate.

[0043] A limit hole 191 is provided on the limit fixing member 19. The limit hole 191 is an arc hole, and the arc is consistent with the rotation direction of the limit fixing member 19. At the same time, a limit pin 21 is installed on the bearing seat 18, and the front end of the limit pin 21 passes through the limit hole 191 to limit the rotation angle of the limit fixing member 19. At the same time, a spring pin 22 is provided on the limit fixing member 19, and correspondingly, a pin hole matching the spring pin 22 is provided on the bearing seat 18. When the rotating shaft 14 is rotated, the locking member 41 is engaged with the locking pin 42. At this time, the spring pin 22 is inserted into the pin hole, so that the limit fixing member 19 cannot rotate, and the locking member 41 and the locking pin 42 will remain in the locked state. Pull out the spring pin 22 from the pin hole, and the limit fixing member 19 can be rotated to release the locked state.

[0044] A sensor 17 is also provided on one side of the locking pin 42 on the second fixing plate 32 for detecting whether the locking member 41 is locked in place with the locking pin 42 .

[0045] like Figure 4 As shown, when the trolley is docked with the production line docking unit 3 at the front end of the production line, the docking blocks 33 on both sides of the second fixed plate 32 will limit the left and right sides of the trolley to prevent the trolley from moving left and right so that the trolley can dock accurately. The distance between the two docking blocks 33 is slightly larger than the width of the carrying platform 21, so that the two docking blocks 33 can limit the left and right sides of the trolley.

[0046] Each docking block 33 has a guide slope 331 on its front side. Meanwhile, four pressing wheels 13 are arranged on the left and right sides of the carrying platform 21. Two pressing wheels 13 form a group. One group of pressing wheels 13 is placed horizontally, and the other group of pressing wheels 13 is placed vertically. The pressing wheels 13 roll relative to the side of the docking block 33 and the guide slope 331 to play a guiding role. The upper surface of the docking block 33 is a plane, and there is a certain gap between the plane and the upper and lower heights of the pressing wheels 13, so that the carrying platform 21 can deflect and move toward the rear end.

[0047] like Figure 3 As shown, there are two rear limit mechanisms 5, which are respectively located at the rear end of the carrying platform 21 near both sides. The rear limit mechanism 5 is fixed and mainly consists of a stand 51 and a blocking block 52. The stand 51 is fixedly mounted on the carrying platform 21 by screws, and the blocking block 52 is mounted on the stand 51 near the product. The blocking block 52 is used to block the product and prevent it from sliding out of the rear end of the trolley.

[0048] Since the rear end of the product is heavier, when the product is placed on the conveying assembly 2, the center of gravity of the product will be close to the rear end of the carrying platform 21. At this time, the carrying platform 21 loaded with the product will deflect at the rear end (i.e., the end close to the trolley handle 7), so that the rear end of the carrying platform 21 is low and the front end is high, and the product will slide toward the rear end of the carrying platform 21. Due to the blocking of the blocking block 52, the rear end of the product is limited and the product will not slide out of the trolley. At this time, when the trolley is pushed, the product will tilt toward the end where the trolley handle 7 is located and will not move.

[0049] The upper end of the first swing rod 61 (i.e., the end away from the contact rod 64) will be vertically upward to block the front end of the product. Similarly, the second swing rod 63 on the product docking unit will assemble the products on the production line.

[0050] When the front end of the trolley docks with the production line docking unit 3 at the front end of the production line, the contact rod 64 on the first swing rod 61 will contact the inclined surface of the top block 62 on the second fixed plate 32, and the second swing rod 63 will contact the inclined surface of the top block 62 on the first fixed plate 9. As the trolley gets closer and closer to the production line, the top block 62 will lift the contact rod 64 upward, and at the same time, one end of the contact rod 64 of the first swing rod 61 and the second swing rod 63 will deflect upward, and the other end will deflect downward. When the trolley is docked in place, the first swing rod 61 and the second swing rod 63 will deflect into place at the same time, releasing the blocking limit on the product. Then rotate the rotating shaft 14, the locking member 41 and the locking pin 42 are engaged, and the trolley and the production line are locked together.

[0051] When the product is pushed manually, it will move along the rollers 22 on the carrier platform 21 toward the rear end (i.e., the end close to the production line). At this time, the center of gravity of the product will gradually approach the rear end of the carrier platform 21, and the carrier platform 21 will gradually deflect toward the rear end. At this time, the front end of the carrier platform 21 is low and the rear end is high, so that the product can slide along the inclined surface to the production line. The pressure wheels 13 on both sides of the carrier platform 21 will contact the docking blocks 33. With the cooperation of the pressure wheels 13 and the docking blocks 33, the deflection angle of the carrier platform 21 can be limited.

[0052] When the product is transferred to the production line, the locking member 41 and the locking pin 42 are unlocked, the trolley is pulled backward, and then the first swing arm 61 and the second swing arm 63 will gradually return to their original positions (i.e., the blocking state), and the second swing arm 63 on the product docking unit will block the product on the production line.

[0053] like Figure 3 As shown, in order to prevent the cart from hitting the production line, two buffers 12 are installed on the carrying platform 21. The two buffers 12 are located near the two ends of the first fixed plate 9. When the cart is docked with the production line docking unit 3, the second fixed plate 32 will hit the buffer 12. The buffer 12 will play a buffering role and reduce the impact of the cart on the production line.

[0054] like Figure 2 As shown, two cushion blocks 11 are installed at both ends of the top of the vehicle body 1 below the carrying platform 21, which are used to support and weigh the carrying platform 21 during the forward and backward deflection of the carrying platform 21. The height of the cushion blocks 11 is lower than the height of the bottom surface of the carrying platform 21.

[0055] Guard plates 10 are installed on both sides and the rear side of the carrying platform 21 to protect the internal structure. Baffle bars 15 are arranged on both sides of the top of the carrying platform 21 to block and limit the left and right sides of the product.

[0056] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
