Description

Technical Field

[0001] This utility model relates to a positioning vehicle drive tooth anti-fall device, belonging to the technical field of mechanical drive anti-deterioration. Background Technology

[0002] The positioning vehicle is used to push train carriages and help them accurately position themselves on the tipper. The positioning vehicle typically consists of multiple longitudinal drives, arranged from top to bottom as a motor, reducer, and drive pinion gear. During operation, the drive pinion gear, due to gravity, always has a downward tendency. Loosening of the pinion gear clamp bolts or uneven force on the pinion gear exacerbates this tendency, eventually causing the drive pinion gear to detach. Once detached, the drive pinion gear falls into the positioning vehicle track pit. The distance between the positioning vehicle track and the positioning vehicle drive rack track fastener is less than the diameter of the drive pinion gear, and the installation height of the positioning vehicle's horizontal wheel is lower than the height of the drive pinion gear. Therefore, after the drive pinion gear detaches, the positioning vehicle's balance wheel will push the fallen drive pinion gear, causing damage to other steel structures in the pit, resulting in significant losses. Therefore, it is necessary to design a positioning vehicle drive pinion gear anti-fall device to meet on-site requirements. Furthermore, conventional technologies, in order to ensure that some components of the equipment remain level, will install structures such as levels, which adds extra structure and lacks structural resettlement capability, thus requiring complex reset structures. Utility Model Content

[0003] This utility model provides a positioning vehicle drive tooth anti-fall device, which solves two main problems: First, it solves the problem of early detection of drive tooth descent. Before the tooth falls, there is usually a slow descent process. The specially designed distance detection limit switch of the tooth anti-fall device can detect the tooth descent phenomenon in the early stage and provide an early warning to prevent the tooth from falling. Second, it solves the problem of damage to the steel structure of the equipment caused by sudden drop of the drive tooth. The sudden drop of the tooth is closely related to the stress on the drive structure. In order to prevent this from happening, the tooth anti-fall device is specially designed with a tray structure and a mechanical alarm structure, which can catch the suddenly falling tooth and generate an alarm. Third, it solves the problem of creative adjustment based on the existing positioning vehicle drive tooth anti-fall device, realizing reset without setting up a complex structure. Fourth, it solves the leveling problem, and at the same time, it eliminates the need to set up a level or other structures in a special location, thus avoiding additional structures and costs.

[0004] The technical solution to the above technical problem is:

[0005] A positioning vehicle drive gear anti-fall device is characterized by comprising: an ear plate, a bracket, a tray, a bearing, a base, a locking plate, pigment balls, and a distance detection limit switch. The ear plate consists of two right-angled fixed plates, each with a through hole. The bracket includes a vertical plate and a horizontal plate, with the horizontal plate fixed to the lower end of the vertical plate. The upper end of the vertical plate and the horizontal plate both have through holes. The ear plate is connected to the upper end of the bracket. The outer side of the base is disc-shaped, with several through holes. The horizontal plate of the bracket is connected to the base. The upper end of the base is connected to the lower end of the tray via a bearing. The locking plate is right-angled and is divided into a first locking plate and a second locking plate depending on its fixed position. At least one first locking plate is connected to the lower end of the tray, and at least one second locking plate is connected to the upper end of the base. The pigment balls are placed on the base. A through hole is provided in the center of the tray. The distance detection limit switch is installed in a threaded hole in the center of the base and passes through the through hole of the tray.

[0006] Furthermore, a fixed stop is welded in the middle of the support frame.

[0007] Furthermore, the tray has an annular slide formed by two circular baffles welded underneath, with slits and threaded holes on the inner side of the slide.

[0008] Furthermore, the bearing is a thrust ball bearing.

[0009] Furthermore, the base has a threaded center and a circular slide formed by two circular baffles welded on it. Inside the slide, a card plate is placed and a pigment ball is accommodated.

[0010] Furthermore, the pigment spheres contain liquid pigment, which can be broken when the tray rotates and drives the platen to rotate, causing the liquid pigment to flow out and triggering a warning.

[0011] Furthermore, the distance detection limit can adjust the distance between the rotary distance detection limit switch and the small tooth.

[0012] Furthermore, it also includes a reset structure, which includes a reset rod and a compression spring. The lower left side of the bracket is also provided with a horizontal support plate with a through hole. The reset rod includes a vertical rod and a horizontal rod with the lower end of the vertical rod. The tray is provided with a cam groove that surrounds the outside of the tray. The cam groove includes at least one peak and at least one recess. The top of the vertical rod is provided with a limiting part. A compression spring is provided between the limiting part and the support plate. The head of the horizontal rod is inserted into the cam groove.

[0013] Furthermore, it also includes a leveling and measuring mechanism, which comprises a measuring mechanism and a leveling mechanism.

[0014] Furthermore, the measuring mechanism includes scale lines on the vertical rod portion of the reset plug, and the horizontal rod portions are all corresponding to the recesses inserted in the cam groove. The multiple recesses have the same height. The leveling mechanism includes a leveling screw, a threaded hole on the fixing stop, the leveling screw being disposed in the threaded hole, and a ball bearing at the lower end of the leveling screw, which makes rolling contact with the upper end of the tray.

[0015] The beneficial effects of this utility model are:

[0016] This utility model discloses a small tooth anti-fall device. On one hand, it enables early detection of the downward trend of the positioning vehicle's drive teeth, featuring high sensitivity in all weather conditions, significantly reducing manual inspection costs. Due to its early detection capability, it can prevent most cases of small teeth falling off, minimizing equipment damage. On the other hand, it provides catchment protection in the event of sudden tooth detachment, preventing the small teeth from falling onto other structures of the positioning vehicle and causing secondary damage, further minimizing equipment loss. By incorporating a reset structure, the tray can be automatically reset; and by incorporating a measuring structure and a leveling structure, the tray and base can be leveled.

The ear plate 1 consists of two right-angled fixed plates, each with through holes. The bracket 2 includes a vertical plate and a horizontal plate, with the horizontal plate fixed to the lower end of the vertical plate. Both the upper end of the vertical plate and the horizontal plate have through holes. The ear plate 1 is bolted to the upper end of the bracket 2. The base 5 has a disc-shaped outer surface with several through holes. The bracket 2... The horizontal plate and base 5 are connected together by bolts. The upper end face of the base 5 is connected to the lower end face of the tray 3 by bearings 4. The clamping plate 6 is right-angled and is divided into a first clamping plate and a second clamping plate according to different fixing positions. At least one first clamping plate 6 is connected to the lower end of the tray 3 by bolts, and at least one second clamping plate 6 is connected to the upper end of the base 5 by bolts. The pigment balls 7 are set or fixed on the base 5. The center of the tray 3 is provided with a through hole. The distance detection limit switch 8 is installed in the threaded hole in the center of the base 5 and passes through the through hole of the tray 3. The assembly sequence from top to bottom is: ear plate 1, bracket 2, tray 3, clamping plate 6, bearing 4, pigment balls 7, base 5, and distance detection limit switch 8. The number of ear plates 1 is three or more, the number of brackets 2 is three or more, the number of trays 3 is one, the number of bearings 4 is one, the number of bases 5 is one, the number of pigment balls 7 is two or more, and the number of distance detection limit switches 8 is one.

[0030] like Figure 2 As shown, the ear plate 1 is made of 10mm thick steel plate bent into shape. The width of the two sides of the bend is equal, and two symmetrical through holes are opened on both sides. The through holes are preferably strip-shaped holes.

[0031] like Figure 3 As shown, the bracket 2 connects the ear plate 1 and the base 5. The bracket is made of 10mm steel plate. The top is connected to the ear plate 1, the bottom is connected to the base 5, and the protruding part in the middle is the fixed stop 17, which restricts the tray 3 from detaching from the top. Under normal conditions, there is a gap between the bracket and the tray 3.

[0032] Figure 4As shown in the image, tray 3 has two circular baffles welded to the bottom of a concentric circle at a certain distance from the center, forming an annular slide. The inner annular baffle is used for the installation of bearing 4. Several clamping plates 6 and pigment balls 7 are connected to the inner side of the slide. The inner side of the slide has slits and threaded holes, which serve to install clamping plates 6 and allow pigment to flow out.

[0033] Figure 5 As shown in the diagram, bearing 4 is a thrust ball bearing, with tray 3 and base 5 connected to both ends of the thrust ball bearing, and it is capable of withstanding large axial loads.

[0034] Figure 6 The diagram shows that the base 5 is a disc with a threaded hole in the center. Two circular baffles are welded onto a concentric circle at a certain distance from the center, forming an annular slide. The inner baffles are fitted with bearings. A retaining plate 6 and a container for pigment balls 7 are placed inside the slide. Symmetrical slits and threaded holes are formed on the inner side of the slide, serving to install the retaining plate and facilitate the flow of liquid pigment. The threaded hole in the center is used to install a distance detection limit switch 8.

[0035] Figure 7 As shown, the pallet 6 is made of 3mm thick steel plate bent into shape, with equal lengths on both sides. The first pallet 6 is installed on the underside of the tray 3 via a threaded connection on one side, and the other side extends freely towards the base 5. The second pallet 6 is installed on the upper side of the base 5 via a threaded connection on one side, and the other side extends freely towards the tray 3. A certain gap is left between the two pallets to prevent interference during rotation.

[0036] Figure 8 The diagram shows that the pigment ball 7 is made of plastic and contains liquid pigment. The pigment ball is placed in the slide between the tray 3 and the base 5. When the tray 3 and the base 5 slide relative to each other, the first plate on the tray 3 and the second plate on the base 5 will misalign and squeeze the pigment ball, and the liquid pigment will flow out through the gap in the base 5, reminding the inspection personnel to check the equipment.

[0037] Figure 9 As shown in the image, the distance detection limit switch 8 is an electrical detection device installed at the center of the base 5, used to detect the position of the drive pinion.

[0038] like Figure 10As shown, in order to facilitate the reset of the tray 3 in the anti-fall device of the positioning vehicle drive tooth, this utility model also provides a reset structure. The reset structure includes a reset rod 11 and a compression spring 12. A horizontal support convex plate 15 is also provided on the lower left side of the bracket 2. The support convex plate 15 is provided with a through hole. The reset rod 11 includes a vertical rod part and a horizontal rod part with the lower end of the vertical rod part. The tray 3 is provided with a cam groove 14 that surrounds the outside of the tray 3. The cam groove 14 includes at least one peak and at least one concave part. A limiting part is provided at the top of the vertical rod part. A compression spring 12 is provided between the limiting part and the support convex plate 15. The head of the horizontal rod part is inserted into the cam groove 14. The specific working process is as follows: through the action of the compression spring 12, the reset rod 11 is kept moving downward, so that the force of the horizontal rod part acts on the cam groove 14, so that the reset rod 11 is held in the concave part of the cam groove 14.

[0039] like Figure 11 As shown, furthermore, to ensure that the tray 3 and the base 5 remain level, a level or similar structure is generally installed to measure the levelness based on the bubble structure, and leveling feet are installed for leveling adjustment. To avoid adding extra structures, this utility model, based on the existing positioning vehicle drive tooth anti-fall device, also includes a leveling measuring mechanism. The leveling measuring mechanism includes a measuring mechanism and a leveling mechanism. The measuring mechanism includes scale lines on the vertical rod portion of the reset rod 11. The horizontal rod portions are all corresponding to the recesses inserted in the cam groove 14, and the height of the multiple recesses is the same. The leveling mechanism is controlled to perform leveling by comparing the scales of the multiple vertical rod portions that protrude from the support protrusion 15. The leveling mechanism includes a leveling screw 16, and a threaded hole is provided on the fixing stop 17. The leveling screw is set in the threaded hole, and a ball is provided at the lower end of the leveling screw 16. The ball rolls in contact with the upper end of the tray 3. The leveling screw 16 is adjusted to achieve leveling of the tray 3 and the base 5. After leveling, the support 2 and the base 5 are threadedly fixed according to the leveled state.

Install the bottom of the bearing 4 inside the slide of the base 5, and connect the clamping plate 6 to the tray 3 and the base 5 with bolts. 3. Place the pigment balls 7 inside the slide of the base 5, with multiple pigment balls 7 placed on both sides of the slide separated by the clamping plate 6. 4. Install the tray 3 on top of the bearing 4. 5. Connect the bottom of the bracket 2 to the through hole of the base 5, as shown. Figure 1As shown. 6. Weld the assembled device to the main steel structure via ear plate 1. This completes the assembly process; the reset structure and leveling measuring mechanism are further designs based on the above embodiments.

[0042] The debugging process consists of the following steps: 1. Rotate the distance detection limit switch 8 to a position 10mm from the bottom of the drive tooth in the threaded hole at the center of the base 5. Then, power on the distance detection limit switch 8. At this time, the indicator light will be off. Gradually rotate the distance detection limit switch 8 to bring it closer to the drive tooth. When the indicator light comes on, rotate the distance detection limit switch 8 two full turns to move it away from the drive tooth and lock the distance detection limit switch 8. The debugging process is now complete.
