Description

Technical Field

[0001] The utility model relates to the technical field of horizontal wheel detection of field bridges, in particular to a horizontal wheel detection device for a field bridge trolley. Background Art

[0002] Port equipment - two horizontal wheels are installed at both ends of the trolley wheel group on the left side of the driver's cab of the field bridge. The shaft of the horizontal wheel is designed with an eccentric sleeve. The horizontal wheel is placed on both sides of the trolley track. By adjusting the eccentric sleeve of the horizontal wheel, the horizontal wheel can be placed in the appropriate position on both sides of the track to ensure the normal operation of the trolley mechanism on the trolley track. In the daily use of the field bridge, the center of gravity of the trolley mechanism will deviate due to factors such as design, load or site environment. In this way, when the trolley is running, the running direction of the trolley horizontal wheel will deviate from the center line of the track, causing the trolley to deviate; the above deviation phenomenon is more common in equipment. When the field bridge trolley deviates, the horizontal wheel at the corresponding position will contact the track, thereby correcting the deviation trend of the trolley. In this process, the track squeezes the horizontal wheel at the corresponding position. Under this working condition, the horizontal wheel bearing will be damaged to a certain extent. When the damage accumulates to a certain stage, the bearing retainer breaks. When the horizontal wheel contacts the track and runs, it will move up and down. When the wear of the bearing and the horizontal wheel axle is further aggravated, the horizontal wheel will fall off the horizontal wheel axle. If the above problems are not discovered and solved in time, it may bring hidden dangers of falling objects or cause machine damage, such as the pressure plate screws being cut off and the horizontal wheel fixing plate being deformed.

[0019] The present invention is further described in detail below in conjunction with 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 used to limit the present invention.

[0020] See also Figures 1 to 4 As shown, the horizontal wheel detection device 200 of the field bridge trolley of the utility model comprises a detection sensor 1 and a detection mechanism 4, wherein the detection mechanism 4 comprises a sensing sheet 47 matched with the detection sensor 1, wherein the sensing sheet 47 is mounted on the upper part of a vertically arranged sensing rod 40, wherein the sensing rod is mounted in a guide tube 48, wherein the guide tube is vertically mounted above the horizontal wheel 130 of the field bridge trolley mechanism 100, wherein the bottom end of the sensing rod 40 extends out of the bottom end of the guide tube 48, is located above the horizontal wheel 130, and contacts with the upper end surface of the horizontal wheel 130, wherein the horizontal wheel 130 is arranged on two sides of a track 140, wherein each of the two sides of the track has a horizontal wheel 130, as shown in FIG. Figure 4 shown.

[0021] In some embodiments, the upper end of the guide tube 48 is provided with a sensing rod positioning nut 44, and the sensing rod passes through the central hole of the sensing rod positioning nut and is placed in the guide tube 48. In some embodiments, the sensing rod positioning nut is a T-nut, having a cylindrical portion that matches the inner wall of the guide tube, and the sensing rod positioning nut is fixed by inserting a top screw 6 that radially passes through the guide tube 48, and the outer circumferential surface of the cylindrical portion has an external thread. By setting the sensing rod positioning nut, the sensing rod can be positioned and conveniently installed in the guide tube.

[0022] In some embodiments, a spring component 45 is mounted on the sensing rod 40, and the upper end of the spring component 45 abuts against the sensing rod positioning nut 44, specifically, is connected to the bottom of the cylindrical portion, and the lower end of the spring component 45 abuts against the top of a guide portion 41 coaxially assembled on the sensing rod 40, and the guide portion 41 is slidably connected to the inner wall of the guide tube 48. Preferably, the guide portion is cylindrical, and its diameter is larger than the diameter of the sensing rod, and the spring component is a spring for resetting the sensing rod.

[0023] In some embodiments, a sensing position limiting rod 42 is arranged on the outer circumferential surface of the guide portion 41, and the sensing position limiting rod 42 is vertically connected to the guide portion 41. The sensing position can be limited by the sensing position sensing rod. The guide tube 48 has a limiting groove 49 that cooperates with the sensing position limiting rod. When the sensing rod moves upward, the sensing position limiting rod and the limiting groove cooperate to limit the movement position of the sensing rod.

[0024] In some embodiments, a ball 43 is installed at the bottom end of the sensing rod 40, which contacts the upper end surface of the horizontal wheel to be detected. When the horizontal wheel moves, the ball contacts the upper side surface of the horizontal wheel to move the sensing rod upward.

[0025] In some embodiments, the sensing sheet 47 is an L-shaped sheet, which is installed on the sensing rod through a sensing sheet positioning adjustment nut 46. There are two sensing sheet positioning adjustment nuts 46, one above and one below, which are installed on the sensing rod through a threaded connection. The horizontal part of the sensing sheet is clamped for installation. There is a hole on the horizontal part of the sensing sheet for easy installation on the sensing rod. The vertical part of the sensing sheet cooperates with the detection sensor 1 for sensing detection.

[0026] In some embodiments, the guide tube 48 is connected to two mounting plates (including a first mounting plate 3 and a second mounting plate 5), and is bolted to the outer surface of the field bridge trolley mechanism through the two mounting plates. The two mounting plates are respectively fixed to the upper and lower parts of the guide tube. The first mounting plate is prefabricated with a mounting hole 31, and the second mounting plate 5 also has a corresponding mounting hole to facilitate the connection with the field bridge trolley mechanism.

[0027] Specifically, the first mounting plate 3 and the second mounting plate 5 are connected to the horizontal wheel mounting part of the shaft assembly 150 for mounting the horizontal wheel on the bridge trolley mechanism 100, and the horizontal wheel mounting part includes an upper horizontal wheel mounting part 110 and a lower horizontal wheel mounting part 120, which are fixedly connected with the first mounting plate 3 and the second mounting plate 5 after being matched with each other. See Figure 4 shown.

[0028] In some implementation schemes, the detection sensor 1 is arranged on a sensor mounting plate 2, and the sensor mounting plate is connected to the outer surface of the field bridge trolley mechanism. Specifically, it can be attached to the outer surface of the first mounting plate on the outside of the first mounting plate, and after the mounting hole on its surface is aligned with a mounting hole on the first mounting plate, it is connected to the field bridge trolley mechanism with bolts.

[0029] When installing the horizontal wheel detection device of the field bridge trolley of the utility model, the horizontal wheel detection device is installed to the position of the fixing bolt above the horizontal wheel, and then the sensing plate positioning adjustment nut is adjusted to adjust the sensing plate to the same height as the limit position of the detection sensor 1, and the sensing position limit rod on the sensing rod is slightly lifted to detect whether the limit position of the detection sensor and the position of the sensing plate are adjusted in place: when the adjustment is completed and meets the requirements, the sensing limit light of the detection sensor will light up; after the sensing position limit rod is slightly lifted, there is no induction between the sensing plate and the detection sensor, and the sensing limit light is off at this time.

[0030] When the field bridge trolley mechanism operates normally, when the horizontal wheel 130 contacts the track 140, the horizontal wheel 130 moves along with the trolley mechanism and rolls smoothly back and forth on the side of the track; at this time, the ball 43 at the bottom of the sensing rod 40 of the field bridge trolley horizontal wheel detection device 200 presses against the upper end surface of the horizontal wheel under the action of the spring component 45 and rolls smoothly.

[0031] When the horizontal wheel assembly has an early failure, such as the internal bearing retainer of the horizontal wheel assembly is damaged, the horizontal wheel will move up and down when rolling on one side of the track 140. When the horizontal wheel moves upward, the upper end surface of the horizontal wheel will push upward against the sensing rod, causing the sensing rod to move upward and the sensing sheet to be disconnected from the detection sensor. At this time, the sensing limit status light of the detection sensor will go out, and the sensing signal will be transmitted to the equipment control system (such as the PLC system) for alarm or prompt, so that the horizontal wheel failure can be detected in real time.

[0032] In the utility model, after receiving the sensing signal transmitted by the detection sensor, the equipment control system can be set to control the field bridge trolley mechanism to stop running and report the damage fault of the trolley horizontal wheel assembly, reminding the equipment management personnel to check the trolley horizontal wheel assembly and take corresponding measures.

[0033] From the above description, it can be seen that the horizontal wheel detection device of the field bridge trolley of the embodiment of the utility model is assembled on the upper part of the vertically arranged sensing rod through the sensing sheet, and the sensing rod is assembled in the guide tube, and the guide tube is vertically installed above the horizontal wheel of the field bridge trolley mechanism, and the bottom end of the sensing rod extends out of the bottom end of the guide tube and is located above the horizontal wheel. In this way, when the horizontal wheel mechanism is worn and moves up and down, the horizontal wheel will contact the bottom of the sensing rod, causing the sensing rod to move upward. By detecting the position change of the sensing sheet by the detection sensor, it can be effectively determined whether the horizontal wheel of the field bridge trolley mechanism is faulty or damaged, thereby realizing real-time detection of the status of the horizontal wheel of the trolley mechanism, and triggering an alarm in the early stage of damage to the horizontal wheel of the field bridge trolley, thereby reminding equipment management personnel to replace the horizontal wheel in time to eliminate hidden dangers.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
