Description

Technical Field

[0001] The utility model relates to the technical field of AGV transport vehicles, in particular to an anti-rollover mechanism of a heavy-duty AGV intelligent transport vehicle. Background Art

[0002] The AGV transporter is an intelligent transport vehicle that can transport goods according to a predetermined route. It can transport light or heavy workpieces. Because of its high degree of automation, it saves time and effort, and improves industrial production efficiency.

[0003] However, when the existing AGV transporter is transporting heavy workpieces, it is inevitable to turn because it follows a predetermined route. Therefore, it must be turned at an extremely low speed, otherwise it will easily roll over and cause huge losses. The existing AGV transporter urgently needs a set of anti-rollover mechanisms on both sides to improve transportation efficiency and safety. In addition, when loading and unloading goods, the goods often cause excessive pressure on one side when moving, so there will be potential dangers, affecting the work safety of the staff. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-rollover mechanism for a heavy-duty AGV intelligent transport vehicle to solve the problems raised in the above-mentioned background technology.

[0006] The anti-rollover base includes an electric telescopic rod, the bottom end of which is fixedly connected to a fixed platform, a universal wheel is rotatably mounted on the bottom end of the fixed platform, a sleeve rod is movably sleeved inside the fixed platform, a spring is movably sleeved on the surface of the sleeve rod, and a fixing plate is fixedly mounted on the top end of the sleeve rod.

[0007] Preferably, support plates are fixedly mounted on both left and right ends of the mounting platform, and rollers are rotatably mounted on both upper and lower ends of the support plate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figures 1 to 4 As shown, an anti-rollover mechanism of a heavy-duty AGV intelligent transporter in the embodiment of the first aspect of the utility model comprises an AGV body 1, a support frame 2 is fixedly installed at the bottom end of the AGV body 1, a mounting platform 3 is slidably installed on the surface of the support frame 2, a connecting seat 5 is fixedly installed in the middle of the bottom end of the AGV body 1, a dual-axis motor 6 is fixedly installed at the bottom end of the connecting seat 5, a screw frame 7 is fixedly sleeved at both left and right ends of the dual-axis motor 6, a limit ring 8 is fixedly installed at the end of the screw frame 7, an anti-rollover base 13 is fixedly installed at the bottom end of the mounting platform 3, a sliding groove 9 is opened inside the rear side of the AGV body 1, and a speed sensor 10 is fixedly installed on the surface of the AGV body 1 below the sliding groove 9;

[0023] The anti-rollover base 13 includes an electric telescopic rod 131, the bottom end of the electric telescopic rod 131 is fixedly connected to a fixed platform 132, the bottom end of the fixed platform 132 is rotatably mounted with a universal wheel 133, the interior of the fixed platform 132 is movably sleeved with a sleeve rod 135, the surface of the sleeve rod 135 is movably sleeved with a spring 136, the top of the sleeve rod 135 is fixedly mounted with a fixing plate 134, the inner side of the fixing plate 134 is fixedly mounted on the outer surface of the mounting platform 3, the top of the electric telescopic rod 131 is fixedly mounted on the bottom surface of the mounting platform 3, one end of the speed sensor 10 is electrically connected to a controller, and the speed sensor 10 is electrically connected to the electric telescopic rod 131 through the controller.

[0024] In the above embodiment, it should be noted that the electric telescopic rod 131 is electrically connected and controlled by the controller speed sensor 10, and the power supply can also be directly controlled. The dual control belongs to the prior art, so it will not be described in detail. Secondly, since the inner and outer rotation speeds are inconsistent when turning, the speed controller is used to identify whether to make a large angle turn.

[0025] The technical effect achieved by the above embodiment is: the sleeve rod 135 is used to make the fixed platform 132 have a certain buffering capacity when supporting, reducing the impact deformation caused by the initial contact moment of the support, and improving the service life of the device. The universal wheel 133 is used to make it easy to move during support, thereby improving its adaptability during the movement.

[0026] Example 2

[0027] like Figure 1 and Figure 3 As shown, an anti-rollover mechanism for a heavy-duty AGV intelligent transporter includes all the contents of Example 1. In addition, support plates 11 are fixedly installed on both left and right ends of the mounting platform 3, and rollers 12 are rotatably installed on both upper and lower ends of the support plate 11. The support plate 11 is slidably installed inside the sliding groove 9 through the rollers 12. A socket groove 301 is opened on the surface of the mounting platform 3, and the support frame 2 is slidably installed inside the mounting platform 3 through the socket groove 301.

[0028] The technical effect achieved by the above embodiment is: the support plate 11 is used to slide inside the sliding groove 9 to ensure the support of the left and right ends of the mounting platform 3, thereby improving its service life, and the sleeve groove 301 and the support frame 2 can ensure that the mounting platform 3 can achieve the limiting function when moving with the screw frame 7, and the mounting platform 3 can also be supported laterally, further improving its service life and preventing breakage.

[0029] Working principle: When the AGV body 1 makes a large angle turn, the speed sensor 10 recognizes different speeds on both sides. The controller controls the electric telescopic rod 131 to start automatically, and moves down on the side with faster speed, that is, the strong side, so that the universal wheel 133 contacts the ground, and then the mounting platform 3 provides inner support to prevent rollover caused by excessive speed. When the goods are loaded and unloaded, the dual-axis motor 6 is started to drive the mounting platform 3 to move to the two outer sides, and finally the electric telescopic rod 131 is directly started to drive the fixed platform 132 to move down, directly supporting both sides, thereby improving the stability of the overall AGV body 1 in loading and unloading goods.
