Description

Technical Field

[0001] This utility model relates to the field of tippler technology, specifically a device for cleaning coal accumulation on a car weighing beam. Background Technology

[0002] The tippler system is mainly used for tipping over train cars loaded with bulk materials. The tippler system is mainly composed of a main steel structure, a car support plate, a car pressure beam and other mechanisms. The car pressure beam mechanism is mainly composed of a car pressure beam, a car pressure beam cylinder, a car pressure beam base, axle pins, bearings, axle sleeves and other components. The car pressure beam mainly plays the role of fixing the train cars during the tippler operation.

[0003] Chinese patent publication number "CN 214692276 U" discloses a "coal dust cleaning device for tipper". Each end of the tipper's pressing beam has a mounting clip on its side, and each mounting clip holds a nozzle. The nozzle's nozzle faces the coal accumulation area. An air tank is installed near the tipper, storing high-pressure air. A steel air duct is installed at the air tank's outlet, and a solenoid valve is mounted on the steel air duct. The nozzle is connected to the steel air duct via a high-pressure rubber hose. The high-pressure rubber hose is fixed in a bracket, which includes a middle bracket fixed to the tipper's frame and an end bracket fixed to the upper side of the pressing beam end. The nozzle of this invention rotates synchronously with the tipper's tipper car body, facilitating coal dust cleaning during or after the tipping process. This device has a simple structure, low cost, easy and convenient setup and control, and high operational safety. The cleaning device of this patent is a split external device. However, coal often accumulates on the rear side of the tippler's pressure beam. Especially with the use of the tippler's dry fog system, damp coal often accumulates on the rear side of the pressure beam and adheres to the rear of the pressure beam. Especially during winter operation, the attached damp coal freezes into ice at low temperatures. When the pressure beam moves up and down, the pressure beam with the icy part presses down into the pressure beam slide, which can cause the pressure beam to get stuck and unable to rise, resulting in a malfunction. To address this, we have proposed a coal accumulation cleaning device for the pressure beam. Utility Model Content

[0004] The purpose of this utility model is to provide a coal accumulation cleaning device for the car tipper beam, in order to solve the problem that coal often accumulates on the rear side of the car tipper beam in the existing technology. During winter operation, the coal is easily frozen into ice, which can cause the car tipper beam to get stuck and unable to rise when it moves up and down, leading to malfunctions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal accumulation cleaning device for a car beam, comprising a base plate, with sliding rods symmetrically fixed to the top of the base plate, an energy storage cleaning mechanism provided on the top of the base plate, and a backstop mechanism provided on the outer side of the sliding rods;

[0006] The energy storage cleaning mechanism includes a sliding plate that slides on the outside of the sliding rod. A cleaning head slides on the outside of the sliding rod and is located on the top of the sliding plate. A connecting seat is symmetrically fixed at the bottom of the sliding plate. A connecting rod rotates inside the connecting seat. A movable seat rotates at one end of the connecting rod. Tension springs are fixed on opposite sides of the two movable seats.

[0007] Preferably, the energy storage and cleaning mechanism further includes a fixed mounting bracket fixed to the top center of the base plate, a limit rod fixed between the two inner sides of the mounting bracket, and a compression spring sleeved on the outer side of the slide rod, located at the bottom of the slide plate.

[0008] Preferably, the movable seat slides symmetrically on the outside of the limiting rod to limit the movable seat, facilitating the movement of the movable seat outside the limiting rod, and the tension spring is sleeved on the outside of the limiting rod.

[0009] Preferably, the anti-reverse mechanism includes slots symmetrically opened on the top of the outer side of the slide rod, an anti-reverse ring sleeved on the outer side of the slide rod, a contraction cavity symmetrically opened on the inner side of the anti-reverse ring, a moving groove through the top center of the contraction cavity, a connecting spring fixed to the center of one side of the contraction cavity, a moving plate fixed to one end of the connecting spring, a pull rod fixed to the top of the moving plate, and an insert block fixed to the center of one side of the moving plate.

[0010] Preferably, the anti-reverse mechanism further includes a positioning groove formed at the top of the slide bar, and positioning blocks are symmetrically fixed on the inner sidewall of the anti-reverse ring to position the anti-reverse ring and facilitate the engagement of the insert block and the slot.

[0011] Preferably, the movable plate is slidably connected to the inside of the contraction cavity, and the outer side wall of the movable plate is in contact with the inner side wall of the contraction cavity, so that the movable plate can move stably inside the contraction cavity.

[0012] Preferably, the pull rod is located inside the moving groove, and the two sides of the pull rod are in contact with the two sides of the moving groove, so that the pull rod can move stably inside the moving groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes an energy-storing cleaning mechanism. By installing the base plate at a designated position, the cleaning head is brought into contact with the rear side of the pressure beam. When the pressure beam descends, the frozen coal compresses the cleaning head, causing it to descend and thus the sliding plate descends, compressing the compression spring. Simultaneously, the connecting seat descends, causing the connecting rod to deflect, which moves the moving seats away from each other outside the limit rod, stretching the tension spring. Energy is stored through the deformation of the tension and compression springs. The greater the deformation, the more energy is stored, and the greater the reaction force. This allows the cleaning head to remove the frozen coal, preventing the pressure beam with icy parts from being pressed into the pressure beam slide, thus preventing the pressure beam from getting stuck and facilitating subsequent lifting. Furthermore, the spring design prevents the cleaning head from rigidly contacting the frozen coal, reducing damage to the cleaning head and extending its service life.

[0015] 2. In this application, by using the anti-reverse mechanism, when the cleaning head is damaged after prolonged use, the pull rods are pulled apart, causing the insert block to move out of the slot, releasing the anti-reverse ring and disassembling it. This facilitates the disassembly and replacement of the cleaning head, making replacement more time-saving and labor-saving. The cleaning head is modularized, and when damaged, only some parts need to be replaced, saving costs. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5 As shown, this utility model provides a technical solution for a coal accumulation cleaning device for a car beam, including a base plate 100, a sliding rod 200 symmetrically fixed on the top of the base plate 100, an energy storage cleaning mechanism 300 provided on the top of the base plate 100, and a backstop mechanism 400 provided on the outer side of the sliding rod 200.

[0024] Please see Figure 2 and Figure 3 The energy-storing cleaning mechanism 300 includes a slide plate 310 that slides outside a slide rod 200. A cleaning head 320 slides on the outside of the slide rod 200 and is located at the top of the slide plate 310. A connecting seat 330 is symmetrically fixed at the bottom of the slide plate 310. A connecting rod 340 rotates inside the connecting seat 330. A movable seat 350 rotates at one end of the connecting rod 340. Tension springs 360 are fixed on opposite sides of the two movable seats 350. The energy-storing cleaning mechanism 300 also includes a mounting bracket 370 fixed to the top center of the base plate 100. A limit rod 380 is fixed between the two sides inside the mounting bracket 370. A compression spring 390 is sleeved on the outside of the slide rod 200 and is located at the bottom of the slide plate 310. The movable seat 350 slides symmetrically outside the limit rod 380, and the tension spring 360 is sleeved on the outside of the limit rod 380. By utilizing the configuration of the energy-storing cleaning mechanism 300, the base plate 100 is mounted on the finger... The cleaning head 320 is positioned so that it fits against the rear side of the pressure beam. When the pressure beam descends, the frozen coal compresses the cleaning head 320, causing it to descend. This, in turn, causes the sliding plate 310 to descend, compressing the compression spring 390. Simultaneously, the connecting seat 330 descends, causing the connecting rod 340 to deflect. This causes the moving seat 350 to move away from the limit rod 380, stretching the tension spring 360. Through the deformation of the tension spring 360 and the compression spring 390, energy is stored. The greater the deformation, the more energy is stored, and the greater the reaction force. This allows the cleaning head 320 to remove the frozen coal, preventing the pressure beam with icy parts from being pressed into the pressure beam slide and preventing it from getting stuck. This facilitates subsequent lifting. Furthermore, the spring design prevents the cleaning head 320 from making rigid contact with the frozen coal, reducing damage to the cleaning head 320 and extending its service life.

[0025] Please see Figure 4 and Figure 5The anti-reverse mechanism 400 includes slots 420 symmetrically opened on the top of the outer side of the slide rod 200. An anti-reverse ring 430 is sleeved on the outer side of the slide rod 200. A contraction cavity 450 is symmetrically opened on the inner side of the anti-reverse ring 430. A moving groove 451 is opened through the middle of the top of the contraction cavity 450. A connecting spring 460 is fixed to the middle of one side of the contraction cavity 450. A moving plate 470 is fixed to one end of the connecting spring 460. A pull rod 471 is fixed to the top of the moving plate 470. An insert block 480 is fixed to the middle of one side of the moving plate 470. The anti-reverse mechanism 400 also includes a positioning groove 410 opened at the top of the slide rod 200. Positioning blocks 440 are symmetrically fixed to the inner side wall of the anti-reverse ring 430. The moving plate 470 is slidably connected to... The shrinkage cavity 450 is located inside, and the outer wall of the moving plate 470 is in contact with the inner wall of the shrinkage cavity 450; the pull rod 471 is located inside the moving groove 451, and the two sides of the pull rod 471 are in contact with the two sides of the moving groove 451; by utilizing the anti-reverse mechanism 400, when the cleaning head 320 is damaged after long-term use, by pulling the pull rod 471, the pull rods 471 are moved away from each other, thereby causing the insert block 480 to move out of the slot 420, releasing the fixation of the anti-reverse ring 430, and disassembling the anti-reverse ring 430, thereby facilitating the disassembly of the cleaning head 320 and making it easier to replace, making the replacement more time-saving and labor-saving, and making the cleaning head mold 320 modular, so that only some parts need to be replaced when damaged, saving costs.

[0026] In use, the base plate 100 is installed in the designated position, so that the cleaning head 320 is in contact with the rear side of the pressure beam. When the pressure beam descends, the frozen coal compresses the cleaning head 320, causing it to descend and thus the sliding plate 310 descends, compressing the compression spring 390. Simultaneously, the connecting seat 330 descends, causing the connecting rod 340 to deflect, so that the moving seats 350 move away from each other outside the limit rod 380, causing the tension spring 360 to stretch. Through the deformation of the tension spring 360 and the compression spring 390, energy is stored. The greater the deformation, the more energy is stored, and the greater the reaction force, thus allowing the cleaning head 320 to remove the frozen coal. This prevents the pressure beam with icy parts from being pressed into the pressure beam slide, preventing the pressure beam from getting stuck and facilitating subsequent lifting. When the cleaning head 320 is damaged after prolonged use, the pull rod 471 is pulled, causing the pull rods 471 to move away from each other, thus moving the insert block 480 out of the slot 420. In the middle, release the fixation of the anti-reverse ring 430 and disassemble the anti-reverse ring 430 to facilitate the disassembly of the cleaning head 320. Then, put the new cleaning head 320 on the outside of the slide rod 200, pull the pull rod 471 again, so that the moving plate 470 drives the insert block 480 to retract into the inside of the contraction cavity 450, compressing the connecting spring 460, putting the anti-reverse ring 430 on the outside of the slide rod 200, so that the positioning block 440 is located inside the positioning groove 410, and loosen the pull rod 471. 71. By resetting the connecting spring 460, the moving plate 470 drives the insert block 480 to reset, so that the end of the insert block 480 fits against the outside of the slide rod 200. The anti-reverse ring 430 continues to move down. When the insert block 480 is aligned with the slot 420, the connecting spring 460 continues to drive the moving plate 470 to reset, so that the insert block 480 is embedded in the slot 420, and the anti-reverse ring 430 is fixed, thereby preventing the cleaning head 320 from falling off the outside of the slide rod 200, and the installation is completed.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
