Description

Technical Field

[0001] This application relates to the technical field of turnover carts, and in particular to a turnover cart that is easy to unload. Background Technology

[0002] Turnover carts are widely used in industrial production, warehousing, logistics and other fields. Turnover carts are divided into hand-push carts and electric carts. Hand-push carts are handled manually and are suitable for short-distance transportation of light goods. They do not require external energy and are characterized by high flexibility and low cost. Electric carts use batteries as a power source and are suitable for long-distance transportation of heavy goods. They are easy to operate but have a higher cost.

[0003] Currently, small and micro enterprises generally use hand-pushed turnover carts for product turnover in industrial production processes. In order to transport a large number of products at one time, the cart body is generally set too deep, making it difficult to remove the products at the bottom during unloading. At the same time, the products are easily bumped or even dropped during loading, unloading and turnover, which not only causes economic losses to enterprises, but also threatens personal safety, resulting in poor safety performance. Utility Model Content

[0004] To facilitate unloading, prevent product damage, and improve safety and versatility during use, this application provides a turnover vehicle that facilitates unloading.

[0005] The transfer vehicle for easy unloading provided in this application adopts the following technical solution:

[0006] A convenient unloading trolley includes a base plate and a frame. The base plate has shock-absorbing casters at its four bottom corners. The frame is fixed above the base plate, and a shell is fixed to the surface of the frame. A handle is located on the side of the shell. The trolley also includes a lifting device, a two-way ratchet mechanism, and a rocker wheel. Mounting seats are located at the top and bottom of the frame. The lifting device is mounted inside the frame via the mounting seats. The two-way ratchet mechanism is fixedly connected to the top of the lifting device. The rocker wheel passes through the shell and is fixedly connected to the side of the lifting device. Several turnover boxes are placed inside the lifting device. An unloading port is located at the top of the shell.

[0007] By adopting the above technical solution, during unloading, the rocker wheel is rotated counterclockwise, which drives the lifting device to move upward, so that several turnover boxes placed inside the lifting device are lifted to the unloading port. At the same time, the bidirectional ratchet mechanism hinders the reverse transmission of the lifting device, preventing the turnover boxes from sliding down due to their own weight, which facilitates the unloading of products.

[0008] Preferably, the lifting device includes a first sprocket group, a second sprocket group, and a transmission mechanism. The first sprocket group and the second sprocket group are arranged in parallel relative to each other. The transmission mechanism is disposed between the first sprocket group and the second sprocket group. One end of the transmission mechanism is rotatably connected to the first sprocket group, and the other end is rotatably connected to the second sprocket group.

[0009] By adopting the above technical solution, the first sprocket set drives the second sprocket set synchronously through the transmission mechanism.

[0010] Furthermore, both the first sprocket assembly and the second sprocket assembly include a first drive shaft, a second drive shaft, a first sprocket, a second sprocket, a first chain, and a second chain. The first drive shaft and the second drive shaft are arranged in parallel. The first sprockets are all fixedly disposed at both ends of the first drive shaft, and the second sprockets are all fixedly disposed at both ends of the second drive shaft. One end of the first chain meshes with the first sprocket on one side of the first drive shaft, and the other end meshes with the second sprocket on one side of the second drive shaft. One end of the second chain meshes with the first sprocket on the other side of the first drive shaft, and the other end meshes with the second sprocket on the other side of the second drive shaft.

[0011] By adopting the above technical solution, the first drive shaft and the second drive shaft in the first sprocket group and the second sprocket group can rotate in the same direction.

[0012] Furthermore, the transmission mechanism includes a third transmission shaft, a first bevel gear, and a second bevel gear. The first bevel gear is fixedly disposed at both ends of the third transmission shaft, and the second bevel gear is fixedly disposed at one end of the first transmission shaft. The second bevel gear meshes with the first bevel gear.

[0013] By adopting the above technical solution, the transmission mechanism causes the second sprocket group to rotate in the opposite direction to the first sprocket group, thereby achieving synchronous lifting and lowering.

[0014] Furthermore, the first sprocket assembly and the second sprocket assembly are provided with several support plates facing each other, and the height between the support plates is adjustable.

[0015] By adopting the above technical solution, several support plates arranged opposite to each other on the first and second sprocket sets can support the turnover box for lifting and lowering. The height between the support plates can be adjusted, which allows the turnover cart to be used for turnover boxes of different heights, thus improving the versatility of the turnover cart.

[0016] Preferably, the bidirectional ratchet mechanism includes a bidirectional ratchet and a pawl reversing assembly. The bidirectional ratchet is fixedly connected to one end of the first drive shaft of the first sprocket assembly, and the pawl reversing assembly is fixed in the frame directly above the bidirectional ratchet. The bottom of the pawl reversing assembly is embedded in the tooth groove of the bidirectional ratchet.

[0017] By adopting the above technical solution, a bidirectional ratchet mechanism is fixedly connected to one end of the first drive shaft of the first sprocket group, so as to realize bidirectional reverse locking of the lifting device during the rising and falling process.

[0018] Furthermore, the pawl reversing assembly includes a spring seat, a connecting rod, a pawl, a spring, a knob, and a positioning pin. The spring seat is fitted onto the connecting rod, the bottom of the connecting rod is connected to the pawl, the spring is disposed between the spring seat and the pawl, the knob is fixedly connected to the top of the connecting rod, and the positioning pin is fixed to the bottom of the knob. The bottom of the spring seat has a groove for accommodating the pawl, and the top of the spring seat has two positioning holes at 180°.

[0019] By adopting the above technical solution, by lifting the knob of the pawl reversing assembly and rotating the knob 180°, the positioning pin at the bottom of the knob is inserted into another positioning hole at the top of the spring seat, thereby rotating the pawl 180° and realizing the pawl reversing function.

[0020] Preferably, the turnover box includes a shock-absorbing mechanism, a long partition and a short partition, a buffer pad is provided on the inner side wall of the turnover box, and the shock-absorbing mechanism is located inside the turnover box; the inner side wall of the turnover box is provided with a number of slots, and the long partition and the short partition are connected to the turnover box through the slots.

[0021] By adopting the above technical solution, long and short partitions are connected by slots inside the turnover box, which can separate the products and prevent them from colliding with each other and causing damage.

[0022] Furthermore, the shock absorption mechanism includes a shelf, a shock absorption spring, and a rubber pad. The shelf is connected to the inner wall of the bottom of the turnover box through the shock absorption spring, and the rubber pad is disposed at both ends of the shock absorption spring.

[0023] By adopting the above technical solution, the shock-absorbing mechanism set at the bottom of the turnover box plays a shock-absorbing role for the product.

[0024] Furthermore, spring plungers are evenly distributed on the long and short partitions.

[0025] By adopting the above technical solution, spring plungers are evenly distributed on the long and short partitions, which can fix and dampen the products in the turnover box. At the same time, the turnover box can be used for products of different specifications, thus improving the versatility of the turnover box.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. A lifting device is installed inside the turnover cart. A two-way ratchet mechanism is fixedly connected to the top of the lifting device, and a rocker wheel is fixedly connected to the side of the lifting device. Several turnover boxes are placed inside the lifting device. When unloading, the rocker wheel is rotated counterclockwise. The rocker wheel drives the lifting device to move upward, so that the turnover boxes placed inside the lifting device are lifted to the unloading port. At the same time, the two-way ratchet mechanism hinders the reverse transmission of the lifting device, preventing the turnover boxes from sliding down due to their own weight, which facilitates the unloading of products.

[0028] 2. By installing a two-way ratchet mechanism at the top of the lifting device, the lifting device can be locked in both directions during the rising and falling process, preventing the turnover boxes placed on the turnover cart from falling due to their own weight, which could cause product damage or personal injury, thus improving the safety of the turnover cart.

[0029] 3. By setting a buffer pad on the inner side wall of the turnover box and setting a shock absorption mechanism inside, and connecting long and short partitions through slot groups, and evenly distributing spring plungers on the long and short partitions, when the turnover box is hit, the buffer pad, shock absorption mechanism, partition assembly and spring plungers work together to effectively buffer the impact force between the turnover box and the product, prevent the product from being bumped and avoid economic losses.

[0030] 4. By evenly distributing spring plungers on the long and short partitions inside the turnover box, the turnover box can be used for products of different specifications. At the same time, the height between the support plates on the first and second sprocket sets is adjustable, allowing the turnover cart to be used for turnover boxes of different heights, thus improving the versatility of the turnover cart.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses a transfer vehicle that facilitates unloading. (See also...) Figure 1 and Figure 2 A turnover cart for easy unloading includes a base plate 1 and a frame 2. The base plate 1 has shock-absorbing casters 3 at its four bottom corners, each with a brake pad. The frame 2 is fixed above the base plate 1, and a shell 4 is fixed to the surface of the frame 2. The shell 4 has a handle 5 on its side, and a rubber sleeve is installed on the handle 5 to increase friction. The turnover cart also includes a lifting device 6, a two-way ratchet mechanism 7, and a rocker wheel 8. The frame 2 has mounting seats 9 at its top and bottom. The lifting device 6 is installed inside the frame 2 through the mounting seats 9. The two-way ratchet mechanism 7 is fixedly connected to the top of the lifting device 6. The rocker wheel 8 passes through the shell 4 and is fixedly connected to the side of the lifting device 6. Several turnover boxes 10 are placed inside the lifting device 6. The top of the shell 4 has an unloading port 41. During unloading, the rocker wheel 8 is rotated counterclockwise, which drives the lifting device 6 to move upward, causing several turnover boxes 10 placed inside the lifting device 6 to be lifted to the unloading port 41. At the same time, the bidirectional ratchet mechanism 7 hinders the reverse transmission of the lifting device 6, preventing the turnover boxes 10 from sliding down due to their own weight, thus facilitating the unloading of the products.

[0039] Reference Figure 3The lifting device 6 includes a first sprocket set 61, a second sprocket set 62, and a transmission mechanism 63. The first sprocket set 61 and the second sprocket set 62 are arranged in parallel with each other. The transmission mechanism 63 is located between the first sprocket set 61 and the second sprocket set 62. One end of the transmission mechanism 63 is rotatably connected to the first sprocket set 61, and the other end is rotatably connected to the second sprocket set 62. The first sprocket set 61 drives the second sprocket set 62 synchronously through the transmission mechanism 63.

[0040] Reference Figure 3 The first sprocket assembly 61 and the second sprocket assembly 62 each include a first drive shaft 621, a second drive shaft 622, a first sprocket 623, a second sprocket 624, a first chain 625, and a second chain 626. The first drive shaft 621 and the second drive shaft 622 are arranged in parallel. The first sprockets 623 are fixedly disposed at both ends of the first drive shaft 621, and the second sprockets 624 are fixedly disposed at both ends of the second drive shaft 622. One end of the first chain 625 meshes with the first sprocket 623 on one side of the first drive shaft 621, and the other end meshes with the second sprocket 624 on one side of the second drive shaft 622. One end of the second chain 626 meshes with the first sprocket 623 on the other side of the first drive shaft 621, and the other end meshes with the second sprocket 624 on the other side of the second drive shaft 622. This enables the first drive shaft 621 and the second drive shaft 622 in the first sprocket assembly 61 and the second sprocket assembly 622 to rotate in the same direction.

[0041] Reference Figure 3 The transmission mechanism 63 includes a third transmission shaft 631, a first bevel gear 632, and a second bevel gear 633. The first bevel gear 632 is fixedly mounted at both ends of the third transmission shaft 631, and the second bevel gear 633 is fixedly mounted at one end of the first transmission shaft 621. The second bevel gear 633 meshes with the first bevel gear 632. In use, rotating the rocker wheel 8 drives the first sprocket set 61 and the second bevel gear 633 fixedly mounted thereon to rotate in the same direction. The second bevel gear 633 on the first sprocket set 61 meshes with the first bevel gear 632 at one end of the transmission mechanism 63, and the first bevel gear 632 at the other end of the transmission mechanism 63 meshes with the second bevel gear 633 on the second sprocket set 62. This drives the second sprocket set 62 to rotate in the opposite direction relative to the first sprocket set 61, thereby achieving synchronous lifting and lowering.

[0042] Reference Figure 3Each of the first sprocket group 61 and the second sprocket group 62 has an accessory piece on its chain link. The first sprocket group 61 and the second sprocket group 62 have several support plates 627 mounted opposite each other through the accessory pieces to support the lifting and lowering of the turnover box 10. By adjusting the position of the support plates 627 on the first sprocket group 61 and the second sprocket group 62, the height between the support plates 627 can be adjusted, so that the turnover cart can be used for turnover boxes 10 of different heights, thus improving the versatility of the turnover cart.

[0043] Reference Figure 2 and Figure 3 The bidirectional ratchet mechanism 7 includes a bidirectional ratchet 71 and a pawl reversing assembly 72. The bidirectional ratchet 71 is fixedly connected to one end of the first drive shaft 621 of the first sprocket assembly 61. The pawl reversing assembly 72 is fixed in the frame 2 directly above the bidirectional ratchet 71. The bottom of the pawl reversing assembly 72 is embedded in the tooth groove of the bidirectional ratchet 71, so that the bidirectional ratchet 71 can only rotate in one direction and cannot rotate in the opposite direction, thereby realizing bidirectional reverse locking of the lifting device 6 during the rising and falling process.

[0044] Reference Figure 4 The pawl reversing assembly 72 includes a spring seat 721, a connecting rod 722, a pawl 723, a spring 724, a knob 725, and a positioning pin 726. The spring seat 721 is fitted onto the connecting rod 722, and the bottom of the connecting rod 722 is connected to the pawl 723. The spring 724 is disposed between the spring seat 721 and the pawl 723. The knob 725 is fixedly connected to the top of the connecting rod 722, and the positioning pin 726 is fixed to the bottom of the knob 725. The bottom of the spring seat 721 has a groove for accommodating the pawl 723, and the top of the spring seat 721 has two positioning holes at 180° angles. During reversal, the knob 725 of the pawl reversing assembly 72 is lifted and rotated 180°, causing the positioning pin 726 at the bottom of the knob 725 to insert into the other positioning hole at the top of the spring seat 721, thereby rotating the pawl 723 180° and realizing the reversing function of the pawl 723.

[0045] Reference Figure 5The turnover box 10 includes a shock-absorbing mechanism 101, a long partition 102, and a short partition 103. Reinforcing ribs are distributed on the outer side of the turnover box 10. A buffer pad 104 is provided on the inner side wall of the turnover box 10. The shock-absorbing mechanism 101 is located inside the turnover box 10. The long partition 102 and short partition 103 are provided with slots, which are connected to each other. Several sets of slots 105 are provided on the inner side wall of the turnover box 10, and the long partition 102 and short partition 103 are connected to the turnover box 10 through the slots 105. When the turnover box 10 is impacted, the buffer pad 104 on the inner wall of the turnover box 10 buffers the horizontal impact force, the shock-absorbing mechanism 101 inside the turnover box 10 buffers the vertical impact force, and the long partition 102 and short partition 103 separate the products in the turnover box 10, preventing damage caused by mutual collision.

[0046] Reference Figure 5 The shock absorption mechanism 101 includes a shelf 1011, a shock absorption spring 1012, and a rubber pad 1013. The shelf 1011 is connected to the inner wall of the bottom of the turnover box 10 through the shock absorption spring 1012. The rubber pad 1013 is disposed at both ends of the shock absorption spring 1012 and plays a shock absorption role for the product.

[0047] Reference Figure 5 Spring plungers 106 are evenly distributed on the long partition 102 and the short partition 103, which can fix and dampen the products in the turnover box 10, and at the same time make the turnover box 10 suitable for products of different specifications, thus improving the versatility of the turnover box 10.
