DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figures 1-4 As shown, a ground positioning device suitable for towing type AGV material carts includes a main frame 1 formed by connecting two side frames and a rear end frame, and two guide wheel fixing plates 4 installed above the main frame and arranged apart. The upper surface of the guide wheel fixing plate is provided with a plurality of guide wheels 5 arranged at intervals, and the wheel axles of the guide wheels are perpendicular to the guide wheel fixing plates. Two rotary cylinders 7 are arranged at intervals on the rear end frame of the main frame 1, and a cylinder clamping block 8 is installed on the driving rod of each rotary cylinder; the two side frames of the main frame are installed on two spaced apart anchor plates 2, and two ground guide frames 3 are arranged on the outer side of the anchor plate 2, and an AGV material cart entry and exit channel is formed between the anchor plate and the guide frame.

[0023] In specific applications, the ground positioning device of the utility model adapted to the towing type AGV trolley is arranged on the ground, such as the anchor plate 2 and the ground guide frame 3 are installed on the installation plane by means of bolt connection. When the AGV trolley moves, it enters and exits the device through the AGV trolley entry and exit channel formed between the anchor plate and the guide frame to achieve ground positioning, enters the entry and exit channel, and stops when it reaches the rear end of the main frame to achieve positioning, and then the rotary cylinder is actuated to clamp and position the corresponding position of the AGV trolley through the cylinder clamping block.

[0024] Among them, there are bolt holes or bolt connection ear plates on the anchor plate 2 and the ground guide frame 3, as shown in the figure, which are no longer marked, so as to facilitate connection and fixation with the installation ground.

[0025] In some embodiments, the rotary cylinder is connected to the rear end frame of the main frame through a cylinder mounting seat, wherein the cylinder mounting seat 6 is installed on the main frame 1 by bolt connection; the rotary cylinder 7 is installed on the cylinder mounting seat 6 by bolt connection; the cylinder clamping block 8 and the cylinder clamping block gasket 9 are installed on the rotary cylinder 7 by bolt connection.

[0026] In some embodiments, two buffers 13 are arranged on both sides of the rear end frame of the main frame 1, and each buffer 13 is installed on a corresponding buffer mounting seat 10. Preferably, the buffer 13 is installed on the buffer mounting seat 10 by fastening with nuts, and the buffer mounting seat 10 is installed on the main frame 1 by bolt connection. A blocking block 11 is arranged at the front end of each buffer mounting seat 10.

[0027] Furthermore, a blocking block gasket 12 is arranged between the blocking block 11 and the buffer mounting seat 10. Through the arrangement of the buffer and the blocking block, it can be achieved that after the AGV trolley enters and the end of the AGV trolley moves into position in the channel, the buffer contacts the end of the AGV trolley to prevent the occurrence of rigid collision and damage to the trolley, and the blocking block 11 blocks the end of the trolley, and after the trolley moves into position, the cylinder clamping block clamps the inner side of the trolley end frame to achieve clamping and positioning of the trolley and the blocking portion.

[0028] Preferably, the blocking block 11 and the blocking block gasket 12 are mounted on the buffer mounting seat 10 by means of bolt connection.

[0029] In some embodiments, two travel switches 16 are spaced apart on either side of the rear end frame of the main frame, and the two travel switches 16 are mounted on two in-position detection switch brackets, respectively. The arrangement of the travel switches 16 can detect the proximity between the AGV and the rear end frame of the main frame, and send a detection signal to the rotary cylinder, which then actuates a pressure block (an integral component of the AGV) at the rear end of the AGV to clamp it against a blocking block, thereby facilitating control of the AGV and preventing it from moving once in position.

[0030] In some embodiments, the in-position detection switch bracket includes an in-position detection switch bracket A14 mounted on the main frame and an in-position detection switch bracket B15 mounted on the buffer mounting base. Preferably, the in-position detection switch bracket A14 is mounted on the main frame 1 by fastening with nuts; the in-position detection switch bracket B15 is mounted on the buffer mounting base 10 by fastening with nuts; and the travel switch 16 is respectively mounted on the in-position detection switch bracket A14 and the in-position detection switch bracket B15 by fastening with nuts.

[0031] In some embodiments, the front end of the ground guide frame has a first guide slope, and the front end of the anchor plate, the side frame of the main frame and the guide fixing plate has a second guide slope. The first guide slope and the second guide slope are in an eight-shaped shape. Such an arrangement can facilitate the material cart to enter the channel.

[0032] In some embodiments, the distance from the center of the guide wheel to the outer side of the guide wheel fixing plate is smaller than the radius of the guide wheel, which facilitates guiding the material cart and prevents direct collision between the material cart and the main frame, guide wheel fixing plate, and anchor plate structures.

[0033] In some embodiments, the guide wheel 5 is mounted on the guide wheel fixing plate 4 by fastening with nuts, wherein the guide wheel fixing plate 4 is mounted on the main frame 1 by bolt connection, and the main frame 1 is mounted on the anchor plate 2 by bolt connection.

[0034] The utility model has a simple structure, safe and reliable performance, can adjust the clamping force by itself, and has a very significant application effect; the utility model has a reasonable structural design, is simple and easy to operate, is economical and practical, energy-saving and efficient, and is suitable for ground positioning of AGV material vehicles in various flexible automated production lines. It has a very wide range of applications and a very significant application effect.
