DETAILED DESCRIPTION

[0050] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0051] In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be understood as indicating or implying relative importance. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0053] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0054] A highly stable adaptive track-type intelligent safety monitoring device with a small turning radius is mainly composed of four parts: a load-bearing guide mechanism 200, a driving mechanism 300, an adaptive mechanism 400, and a housing 500.

[0055] like Figure 1 , 2 As shown in FIGS. 3 and 4 , the driving mechanism 300 includes a pair of driving wheels 301 running along the two side surfaces of the web 101 of the I-beam rail 100 , and the driving wheels 301 are driven by respective driving motors 302 .

[0056] The adaptive mechanism 400 includes a load-bearing plate 401 , and an adjustment mechanism is installed below the load-bearing plate 401 ; the driving motor 302 is longitudinally installed on the adjustment mechanism.

[0057] Two sets of load-bearing guide mechanisms 200 are symmetrically arranged on the load-bearing plate 401. A housing 500 is installed below the load-bearing plate 401.

[0058] The load-bearing guide mechanism 200 includes a rotating base 201 , which is assembled above the load-bearing plate 401 through a load-bearing bearing 228 ; load-bearing guide units 202 are symmetrically arranged on both sides of the web 101 of the I-beam track 100 on the rotating base 201 .

[0059] like Figure 5 As shown, the load-bearing guide unit 202 includes a load-bearing guide bracket 203 mounted on a rotating base 201, a load-bearing wheel 204 running along the upper surface of the lower flange 102 of the I-beam track 100 is mounted on the upper portion of the load-bearing guide bracket 203, and a front guide wheel 205 running along the side of the web 101 of the I-beam track 100 is mounted on one side of the load-bearing guide bracket 203. A clamping wheel 206 running along the lower surface of the lower flange 102 of the I-beam track 100 is mounted on the lower portion of the load-bearing guide bracket 203. A side guide wheel 207 running along the side of the lower flange 102 of the I-beam track 100 is mounted on the other side of the load-bearing guide bracket 203.

[0060] The device runs on the I-beam track 100, and the driving mechanism 300 provides forward power. The two driving wheels 301 on both sides are controlled by the adaptive mechanism 400, and fit with the web 101 of the I-beam track 100. The driving motor 302 generates driving force to drive the entire track-type intelligent safety monitoring device to move. A total of four load-bearing wheels 204 located on both sides of the track bear the entire weight of the track-type intelligent safety monitoring device. The four front guide wheels 205 located on both sides of the track are always in contact with the side of the web 101 of the I-beam track 100 through the force of their respective torsion springs 2016. The four clamping wheels 206 located on both sides of the track are always in contact with the lower surface of the lower flange 102 under the action of the spring force of their respective compression springs I 224, so that the load-bearing wheels 204 that support the load are in contact with the upper surface of the lower flange 102. The four side guide wheels 207 located on both sides are in contact with the side surface of the lower flange 102 of the I-beam. Through the combined use of the load-bearing and guide wheel systems, the entire track-mounted intelligent safety monitoring device only maintains the forward and backward movement freedom, and the freedom in other directions remains flexibly constrained, making the entire track-mounted intelligent safety monitoring device more stable during movement.

[0061] The components and functions of the device of the present invention are specifically described as follows.

[0062] (1) Load-bearing guide mechanism A set of load-bearing guide mechanisms are arranged at the front and rear of the track-type intelligent safety monitoring device. The main functions are: 1.

The front and rear load-bearing guide mechanisms realize flexible rotation around two points through the load-bearing bearings connected to each other, realize the turning function of the equipment, and greatly reduce the turning radius of the equipment.
