Description

Technical Field

[0001] This utility model relates to a walking mechanism for monitoring equipment, specifically an adjustable track walking mechanism. Background Technology

[0002] In power equipment distribution rooms, a large number of monitoring devices are typically invested in to meet the need for unattended monitoring. Although different monitoring devices can monitor different operating equipment in the distribution room, their investment costs are high. To reduce costs, the method of arranging tracks in the distribution room has gradually emerged to reduce the investment in monitoring devices. Specifically, specific tracks can be designed in front of rows or columns of power equipment, and individual or single sets of monitoring devices can be suspended on the tracks to monitor a row or column of power equipment. This method can effectively reduce the investment in monitoring devices. However, in general, the monitoring devices are usually mounted on the tracks by pulleys on the traveling mechanism. With long-term use, wear on the pulleys or displacement of the tracks will affect the reliability of their operation, affect the monitoring effect, and may even cause the traveling mechanism and the monitoring devices to fall off the tracks together, resulting in serious property damage. Therefore, how to ensure the reliability of the monitoring equipment has become an urgent technical problem to be solved. Summary of the Invention

[0018] The adjustable tension track walking mechanism of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] As shown in the figure, the adjustable tension track walking mechanism of this utility model includes an I-shaped track 1, a seat plate 2 located below the track, and two pairs of guide wheel assemblies 3 mounted on the seat plate, which press against the left and right sides of the track 1 respectively. Figure 4 The left and right directions shown are defined as front and back sides) and pressing on the left and right sides of track 1 ( Figure 4 The vertical direction is defined as left and right sides. A pair of traveling wheel assemblies 4, each driven by its own power unit (a drive motor), are shown. Each traveling wheel assembly includes a bushing 35 and a traveling wheel, in addition to the drive motor. The output shaft of the drive motor connects to the traveling wheel via the bushing, thus driving the traveling wheel to rotate. A hanger 34 is provided at the top of the track 1, allowing the track to be mounted on the roof of the equipment room or factory building. Two adjustment slots 5 are provided on the seat plate 2. The left adjustment slot allows the left traveling wheel assembly 4 to move laterally, and the right adjustment slot allows the right traveling wheel assembly 4 to move laterally (e.g., ...). Figure 3 , Figure 4 As shown, a top cover 29 is installed on the top of the seat plate 2. The top cover 29 has a top groove. The guide wheel assembly 3 and the walking wheel assembly 4 both extend out of the top groove and are installed in conjunction with the rail to achieve hoisting. At the same time, a bottom shell 30 is provided at the bottom of the seat plate 2. A conventional monitoring device 31 is suspended on the bottom shell 30. An adjustment assembly 6 for lateral adjustment of the two walking wheel assemblies is provided at the bottom of the seat plate 2. The adjustment assembly 6 has two pairs of push assemblies 7. One pair of push assemblies cooperates with the left walking wheel assembly, and the other pair of push assemblies cooperates with the right walking wheel assembly, thereby pushing the corresponding walking wheel assembly to move laterally in their respective adjustment grooves 5. By adjusting the adjustment assembly 6, the two pairs of push assemblies 7 can synchronously drive the pair of walking wheel assemblies to move relative to each other or in opposite directions to achieve tension adjustment.

[0020] Furthermore, the aforementioned adjusting assembly 6, in addition to having a pair of pushing components, also includes a pair of adjusting rods 8 located on the front and rear sides of the pair of traveling wheel assemblies 4, a bidirectional screw 9 for adjusting the pair of adjusting rods, and a pair of springs 10 mounted on each adjusting rod. Figure 4 As can be seen, in this embodiment, the bidirectional screw 9 is arranged on the rear side ( Figure 4 On the side of the adjusting rod (as shown on the right), two pairs of pushing components 7 are respectively installed on each adjusting rod and the bidirectional screw and placed on the left and right sides of each walking wheel assembly 4 to push the walking wheel assembly 4 to move laterally.

[0021] Furthermore, such as Figure 6 , Figure 7As shown, each pair of pushing components 7 includes a first moving frame 11 and a second moving frame 12, a first connecting plate 13 and a second connecting plate 14 respectively disposed on the front and rear edges of the first moving frame 11, a third connecting plate 15 and a fourth connecting plate 16 respectively disposed on the front and rear edges of the second moving frame 12, and a threaded sleeve 17 for cooperating with a bidirectional screw installed on the fourth connecting plate 16 of the second moving frame. The first moving frame 11 and the second moving frame 12 span the left and right sides of the bushing of each traveling wheel assembly, directly pushing the bushing to move laterally. Figure 4 (The vertical direction is defined as horizontal) does not affect the rotation of the motor output shaft. The first connecting plate 13, the second connecting plate 14, the third connecting plate 15, and the fourth connecting plate 16 are all fitted on each adjusting rod and the double screw. The first spring 10 is fitted on each adjusting rod and presses between the first connecting plate 13 and the third connecting plate 15, and between the second connecting plate 14 and the fourth connecting plate 16 of each pair of push components. In addition, in order to ensure the reliability of operation, the first connecting plate 13, the second connecting plate 14, the third connecting plate 15, and the fourth connecting plate 16 are all equipped with sliding sleeves 18 fitted on each adjusting rod 8.

[0022] Furthermore, a pressure plate 19 is installed between the rear adjusting rod and the bidirectional screw to synchronously press the threaded sleeve 17 of the bidirectional screw 9 and the sliding sleeve located next to the threaded sleeve 17. The adjusting rod 8 and the bidirectional screw 9 are installed at the bottom of the seat plate through the support base 32. Both ends of the bidirectional screw 9 are provided with adjusting parts (square structure) 33 for adjusting the tightness.

[0023] Furthermore, each guide wheel assembly 3 includes a support 20, a lower guide wheel 21 mounted on the support and pressing against the lower guide surface of the rail, and an upper guide wheel 22 mounted on the support and abutting against the upper guide surface of the guide rail. The support 20 is provided with a bracket 24 having a bent top plate 23, a support plate 25 mounted on the bracket, an L-shaped plate 26 for mounting the upper guide wheel, and a second spring 27 pressed between the L-shaped plate and the support plate. The second spring 27 is positioned and installed by bolts 28 that pass through the bent top plate, the L-shaped plate, and the support plate in sequence.

[0024] Its adjustment principle is as follows: When it is necessary to press the traveling wheels firmly against both sides of the track, taking the right-side adjustment part as an example, the right-side adjustment part 33 is adjusted with a wrench to rotate the bidirectional screw 9. Since the helixes of the bidirectional screw 9 are in opposite directions, the right-side push assembly moves to the left under the action of the screw sleeve. During this process, the second moving frame 12 drives the third connecting plate 15 and the fourth connecting plate 16 to move, while simultaneously pressing the first spring, which in turn pushes the first connecting plate 13 and the second connecting plate 14 to move the first moving frame 11 synchronously. Since the bushing is located between the first moving frame 11 and the second moving frame 12, the first moving frame 11 and the second moving frame 12 will push the bushing towards the center of the track beam until the traveling wheels are pressed firmly against the track beam. At the same time, since the helixes of the bidirectional screw 9 are in opposite directions, the left-side push assembly moves to the right, realizing that the two traveling wheel assemblies move synchronously towards the center of the track beam, achieving the pressing purpose. Conversely, to loosen the pressing degree, simply adjust the adjustment part in the opposite direction.

[0025] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
