[0039] The technical scheme of the utility model will be further described below in combination with the drawings and examples.

[0040] As Figures 1-4 The lifting safety protection device for intelligent guided vehicle of the exemplary embodiment of the utility model includes support bracket 1, support rod 2 and support bolt 3.

[0041] The support bracket 1 includes vertically arranged circular support pipe 11, such as steel pipe, and three triangular legs 12 arranged equidistantly along the circumference on the outer wall of the support pipe 11.Specifically, the three triangular legs 12 are all right-angled triangular shape, and all take the support pipe 11 as one of the straight sides, and the other straight side (i.e.the base) and the hypotenuse can preferably be made of pipe material, such as square steel pipe;The hypotenuse bottom end surface of each triangular leg 12 is taken as the support bottom surface, and the lower end of the support pipe 11 and the three base edges are all not lower than the horizontal plane where the support bottom surface of the three triangular legs 12 is located.In this way, on the one hand, the leg is designed in triangular shape, with high structural strength, and is made of pipe material, so it is light in weight;On the other hand, the device bottom is structured as "triangular support", which can better utilize the triangular stability to improve the support stability of the device.

[0042] The support rod 2 is coaxially inserted and fixed on the upper end of the support pipe 11, and the height position is adjustable. In some embodiments, radial insertion holes 21 are respectively formed through the support rod 2 at different height positions, for example, three radial insertion holes 21 are uniformly arranged at intervals upward and downward; the pipe wall of the support pipe 11 is radially split to form support hole positions 111, so that when the device is used for lifting protection, the depth of the support rod 2 inserted into the support pipe 11 can be adjusted according to the lifting protection height requirement of different vehicles, the corresponding radial insertion hole 21 is aligned with the support hole position 111, and then the pin 4 is inserted to fix the support rod 2, so that the device can be quickly and roughly adjusted to the approximate height of the lifting protection. In some preferred embodiments, the support hole position 111 is an arc-shaped recess formed at the upper end of the support pipe 11 to facilitate quick adjustment and fixing of the height of the support rod. Further, the support hole position 111 has four, which are uniformly distributed along the circumference of the pipe opening. It can be understood that two are taken as a group, and there are two groups, so that when the height of the support rod 2 is adjusted, the radial insertion hole 21 can be aligned with the nearest group of support hole positions 111, so as to further speed up the height adjustment operation.

[0043] The support bolt 3 is coaxially screwed on the upper end of the support rod 2, which facilitates quick and accurate fine adjustment of the overall height of the device to the actual lifting protection height required by thread adjustment, so that the top of the support bolt 3 tightly abuts the lifting stress point of the intelligent guided vehicle frame and is tightly pressed, and the lifting protection is performed.

[0044] Each of the triangular legs 12 is provided with a mobile wheel set 5 with a self-adaptive spring design through a fixed plate 121. Specifically, two fixed plates 121 are fixed on the side wall of the triangular leg 12, and the two fixed plates are arranged at an interval upward and downward, and the openings are aligned; the mobile wheel set 5 includes a wheel frame and a spring 51, the wheel frame includes a roller mounting portion 52 and a circular lifting shaft 53, the roller mounting portion 52 is rotationally connected to the lower end of the lifting shaft 53, the lower part of the lifting shaft is provided with an annular platform 531, the lifting shaft 53 is movably arranged in the openings of the two fixed plates 121, and the annular platform 531 on the lifting shaft 53 is located above the lower fixed plate, and the outer diameter of the annular platform is greater than the hole diameter of the fixed plate opening, and the spring 51 is sleeved on the lifting shaft 53 and the two ends are respectively abutted on the upper side of the annular platform 531 and the lower side of the upper fixed plate 121. Figure 5As shown, when the device is empty, the spring 51 is stretched, the lifting shaft 53 is lowered relative to the fixed plate 121 (up to the annular platform 531 abutting the lower fixed plate 121), the rollers 54 of each mobile wheel set 5 extend downward and can roll on the ground, and each triangular leg 12 is suspended, so that a single person can easily move the device, and the device can be conveniently and quickly moved to different vehicles or different force points for lifting and protection work; when the device is loaded, the spring 51 is compressed, the lifting shaft 53 is raised relative to the fixed plate 121, the rollers 54 of each mobile wheel set 5 are retracted upward and cannot roll, and each triangular leg 12 is grounded and tightly abuts the force, thereby realizing stable support and preventing slipping.

[0045] The support rod 2 can be made of a rod or a pipe, preferably a circular pipe, which is convenient for processing, conducive to lightweight design of the device, and facilitates threaded connection with the support bolt 3. For example, the support rod 2 can be connected with the support bolt 3 through internal threads provided on the inner wall of the upper end of the circular pipe. The two through holes in the radial direction on the wall of the support rod 2 made of a circular pipe together form a radial insertion hole 21 that penetrates the support rod.

[0046] In some embodiments, a non-slip pad such as a rubber pad is provided at the top of the support bolt 3 and the support bottom surface of each of the three triangular legs 12, so as to increase the contact friction between the top of the device and the lifting force point of the vehicle frame of the intelligent guided vehicle and between the bottom of the device and the ground, and further ensure stable support.

[0047] In other embodiments, two handles 112 are symmetrically provided on the outer wall of the support pipe 11 for facilitating personnel to move the device.

[0048] In use, the intelligent guided vehicle is first lifted to a specified height by the lifting machine, the device is moved to below the force point of the vehicle, it is ensured that there is no debris below the support bracket and that the device is stably placed on the ground, the support rod is adjusted to a lifting and protection height, the support rod is then fixed by using a latch, and finally the support bolt is rotated to make the top thereof tightly abut the force point. It should be noted that one intelligent guided vehicle generally needs to be lifted and protected by four devices, and the four devices are respectively located below the four corners of the vehicle, so as to better support the intelligent guided vehicle and ensure safety during maintenance.

[0049] The device is convenient to disassemble, store, and transport, and is easy to use, which can save manpower and improve the efficiency of daily maintenance of the intelligent guided vehicle.

[0050] The above description is only a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent substitutions or changes to the technical scheme and concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
