DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] The present embodiment provides a goods transfer device, which is mainly used for the transfer of heavy objects when a person works alone. The transfer device uses a transfer trolley to assist the loading and unloading of goods, saves manpower, and improves the transfer efficiency of goods.

[0032] As Figure 1As shown, the cargo transfer device is actually a transfer trolley, which comprises a chassis 1, as shown in Figure 5 As shown, the bottom of the chassis 1 is provided with a roller 12, thereby realizing the movement of the transfer trolley.

[0033] In order to facilitate the pushing of the transfer trolley, in the embodiment, as shown in Figure 1 As shown, the front side of the transfer trolley is fixedly provided with a handle 11, thereby assisting the movement of the transfer trolley.

[0034] The existing transfer trolley is provided with a roller 12 at the bottom of the chassis 1, thereby causing a certain height between the chassis supporting surface and the ground; when transferring the cargo, the cargo needs to be manually carried onto the chassis before the cargo can be transferred. If the cargo is heavy, one person cannot lift the cargo, thereby affecting the transfer efficiency of the cargo.

[0035] Therefore, in the embodiment, as shown in Figure 5 and Figure 6 As shown, the upper side of the chassis 1 is provided with a bearing plate 2, wherein the chassis 1 is provided with a turnover assembly for driving the bearing plate 2 to switch between a first state and a second state; in the first state, as shown in Figure 5 The bearing plate 2 is in a horizontal state, and the tail of the rear side of the bearing plate 2 is out of contact with the ground; in the second state, as shown in Figure 6 The bearing plate 2 is inclined, wherein the tail of the bearing plate 2 is in contact with the ground, thereby facilitating the transfer of the cargo onto the bearing plate 2.

[0036] Generally, the bearing plate 2 has a certain thickness, as shown in Figure 10 At this time, a step is formed between the tail of the bearing plate 2 and the ground, which is not convenient for moving the cargo onto the bearing plate 2. Therefore, in the embodiment, as shown in Figure 6 The tail of the bearing plate 2 is provided with an inclined downward inclined surface 24, when the bearing plate 2 is in the second state, at this time, the inclined surface 24 of the bearing plate 2 abuts against the ground, thereby eliminating the step formed between the bearing plate 2 and the ground, facilitating the pushing of the cargo onto the bearing plate 2.

[0037] In order to abut the tail of the bearing plate 2 against the ground under the driving of the turnover assembly, in the embodiment, as shown in Figure 2 The turnover assembly comprises a first motor 3 and a turnover disc 32, as shown in Figure 7 The output shaft of the first motor 3 is fixedly connected with the turnover disc 32, as shown in Figure 4 The turnover disc 32 is fixedly provided with a connecting column 321 eccentric to the output shaft of the first motor 3, as shown in Figure 2As shown, the right side wall of the bearing plate 2 is provided with a plug-in hole 23; wherein the connecting column 321 is plugged into the plug-in hole 23 to form a rotating connection, the side wall of the bearing plate 2 is provided with a sliding groove 22 which is inwardly recessed and arranged along the length direction of the bearing plate 2, and the chassis 1 is fixedly provided with a plug-in column 14 which is plugged into the sliding groove 22.

[0038] In the embodiment, as shown in Figure 2 The left and right sides of the chassis 1 are provided with vertical baffles upward, wherein the baffles are provided with left and right plug-in grooves 13, the plug-in column 14 passes through the plug-in groove 13 and extends into the sliding groove 22, and the plug-in column 14 is fixed on the baffle by bolts.

[0039] The baffle here plays a role of preventing the goods on the bearing plate 2 from sliding off from the side.

[0040] Through the above arrangement, as shown in Figure 7 At this time, the bearing plate 2 is in a horizontal state, the plug-in column 14 is plugged into the sliding groove 22 and close to the tail of the bearing plate 2, at this time, the first motor 3 is driven to drive the turnover disc 32 to turn clockwise by 90 degrees, at this time, the bearing plate 2 is raised upward under the action of the connecting column 321, since the plug-in column 14 is fixed on the chassis 1, at this time, the sliding groove 22 and the plug-in column 14 move relatively, so that the bearing plate 2 is in a second state, as shown in Figure 8 At this time, the plug-in column 14 is plugged into the sliding groove 22 and away from the tail of the bearing plate 2, at this time, the tail of the bearing plate 2 abuts against the ground, thereby realizing the switching of the two states of the bearing plate 2.

[0041] In order to improve the stability of the upward turning of the bearing plate 2, in the embodiment, as shown in Figure 2 and Figure 7 The chassis 1 is rotatably connected with a first rotating shaft 31 which is located below the bearing plate 2, wherein the output shaft of the first motor 3 is fixedly connected with the first rotating shaft 31, the left and right sides of the bearing plate 2 are both provided with a turnover disc 32 which is fixed on the first rotating shaft 31.

[0042] In order to facilitate the transfer of the goods on the ground to the bearing plate 2 in the second state, as shown in Figure 2 The left and right side walls of the bearing plate 2 are both rotatably connected with an extension mechanism which extends along the length direction of the chassis 1, the extension end of the extension mechanism is provided with a drag plate 63, in the process of transferring the goods to the bearing plate 2, the extension mechanism is first extended outward to drive the drag plate 63 to move backward, then the extension mechanism is rotated and the drag plate 63 is turned to the rear side of the goods, so that the drag plate 63 abuts against the side wall of the goods, as shown in Figure 6As shown, at this time, the telescopic mechanism is retracted to the front side, the goods are pushed forward by the drag plate 63, and then the goods are transferred to the carrying plate 2.

[0043] In order to assist the movement of the goods, in the embodiment, as shown in Figure 2 The telescopic mechanism includes a shell 61, a telescopic column 62, and a power mechanism for realizing the telescoping of the telescopic column 62, wherein the shell 61 is installed on the left and right side walls of the carrying plate 2 through the rotating shaft 7, and the drag plate 63 is installed on the end of the telescopic column 62.

[0044] The telescoping of the telescopic column 62 is driven by the power mechanism, thereby changing the position of the drag plate 63, and the movement of the goods is realized by the movement of the drag plate 63.

[0045] In order to realize the telescoping of the telescopic column 62, in the embodiment, the power mechanism includes a third motor 64 fixed on the shell 61, and a lead screw threadedly matched with the telescopic column 62 is arranged in the shell 61, wherein the output end of the third motor 64 is fixedly connected with the lead screw.

[0046] The drag plate 63 needs to be in contact with the goods during the process of pushing the goods to move forward. Due to the telescoping of the telescopic column 62, relative rotation between the telescopic column 62 and the drag plate 63 occurs. Therefore, in the embodiment, as shown in Figure 9 A ball pin pair is formed between the telescopic column 62 and the drag plate 63, wherein the end of the telescopic column 62 is connected with a ball head pin, and the drag plate 63 is fixedly connected with a ball bowl for inserting the ball head pin. Thus, the relative rotation between the telescopic column 62 and the drag plate 63 is realized.

[0047] When the goods are transferred to the carrying plate 2 in the second state, the first motor 3 is driven to rotate counterclockwise by 90 degrees at this time, and the carrying plate 2 is switched from the second state to the first state. At this time, the goods are located at the tail of the carrying plate 2, and the gravity is located at the tail of the transfer trolley, which is not conducive to the balance of the transfer trolley. Therefore, in the embodiment, as shown in Figure 2 The driving device for driving the goods to move forward and backward is arranged on the carrying plate 2.

[0048] In the embodiment, as shown in Figure 2 and Figure 3 A plurality of downwardly penetrating notches 21 are arranged on the carrying plate 2, and the driving device includes a roller shaft 41 arranged in the notches 21, wherein the side edges of the roller shaft 41 extend out of the upper end surface of the carrying plate 2, and the second motor 4 for driving the roller shaft 41 to rotate in the same direction is arranged in the carrying plate 2. A plurality of roller shafts are arranged in three rows along the length direction of the carrying plate 2, and the axis of the roller shaft 41 is consistent with the width direction of the carrying plate 2. When the goods are moved to the carrying plate 2, the bottom of the goods is in contact with the outer wall of the roller shaft 41.

[0049] To increase the friction between the roller 41 and the goods, tooth marks are provided on the outer circular surface of the roller 41.

[0050] To achieve synchronous and unidirectional rotation of the rollers 41, in this embodiment, as follows: Figure 3 As shown, the bottom of the support plate 2 is provided with several sets of second rotating shafts 53, wherein the axis of the second rotating shaft 53 is consistent with the width direction of the support plate 2, and several second rotating shafts 53 are arranged sequentially along the length direction of the support plate 2. The roller shaft 41 is fixed on the second rotating shaft 53, and the output end of the second motor 4 is fixedly connected to the second rotating shaft 53. In this embodiment, a sprocket set is provided between two adjacent second rotating shafts 53.

[0051] In this embodiment, the sprocket assembly includes sprockets 51 fixed on the second rotating shaft 53. The sprockets 51 on two adjacent second rotating shafts 53 are connected by a chain 52, thereby enabling the roller shaft 41 to rotate synchronously in the same direction.

[0052] In this embodiment, the second motor 4 is a stepper motor capable of forward and reverse rotation, which facilitates the forward and backward movement of goods on the support plate 2 and makes loading and unloading of goods convenient.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
