Description

Technical Field

[0001] The utility model relates to the technical field of bulk material loading and unloading mechanical equipment, in particular to a novel device for preventing a tipping machine from rotating out of control. Background Art

[0002] A car tipper is a large-scale mechanical equipment used to tip over railway open cars. It is suitable for large thermal power plants, chemical plants, cement plants, ports, storage and transportation stations, and coking plants and sintering plants in the metallurgical industry. It is used to tip over coal, ore and other bulk materials carried by various standard-gauge railway open cars.

[0003] The tipping machine can perform 0°~175° forward tipping and 175°~0° reverse tipping. It is driven by a motor reducer. The tipping machine can unload materials when it is turned forward. When it stops, it is braked by the brake between the motor and the reducer. Under normal conditions, when the tipping machine stops and loses power, it is generally in zero position, and the platform track of the supporting beam is aligned with the ground railway track line. At this time, since the center of gravity of the tipping machine is not the center of the tipping machine's flipping, a huge eccentric torque will be generated, and the tipping machine will lose control and rotate. At this time, the brake is used for braking. When the tipping machine is flipping or turning back at 0°~175°, if there is a sudden power outage or equipment failure, the tipping machine may stop at any angle. Since the center of gravity of the tipping machine is not the center of the tipping machine's flipping, a huge eccentric torque will cause the tipping machine to lose control and rotate. At this time, braking is the only safety measure for the tipping machine.

[0004] If the braking force of the brake adjustment is insufficient or the friction plate is worn and ineffective, the tipping machine will lose control and rotate, causing a production safety accident. Adding a set of protection devices can eliminate the safety hazards of the tipping machine and increase the safety and reliability of the tipping machine. For this reason, we propose a new device to prevent the tipping machine from losing control and rotating. Utility Model Content

[0017] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0018] Embodiment 1:

[0019] like Figure 1-Figure 4 As shown, a novel device for preventing a car tipping machine from rotating out of control comprises a car tipping machine support base 7, a manual propeller 14, a scissor jack 13, a fixed rack 10, a left limit adjustment bolt 9, a right limit adjustment bolt 11 and a positioning platform 12 are respectively arranged on the top of the car tipping machine support base 7, and two groups of rollers 5 are arranged on the top of the car tipping machine support base 7, the manual propeller 14, the scissor jack 13, the fixed rack 10, the left limit adjustment bolt 9, the right limit adjustment bolt 11 and the positioning platform 12 are all arranged between the two groups of rollers 5, the scissor jack 13 and the manual propeller 14 are both located on the top of the positioning platform 12, and the left limit adjustment bolt 9 is arranged on the top of the positioning platform 12. Bolts 9 and right limit adjustment bolts 11 are located on both sides of the fixed rack 10; a tipper end plate 1 is provided at the top of the two groups of rollers 5, and a device 6 is provided at the connection between the tipper end plate 1 and the tipper support base 7 to prevent the tipper from losing control and rotating, and a tipper driving device 4 is provided at one end of the tipper end plate 1, a railway open car 2 and a supporting beam platform 3 are provided on the inner side of the tipper end plate 1, and a gear ring 8 is provided on the outer side of the tipper end plate 1; the scissor jack 13 includes a left displacement scissor jack 15 and a right-left displacement scissor jack 16, and the left displacement scissor jack 15 and the right-left displacement scissor jack 16 are symmetrically arranged with the fixed rack 10 as the center;

[0020] When the tipper is overhauling the brakes or other faults, or when the tipper is stopped and needs to be protected, the tipper can be stopped at any angle. To prevent the brake from failing, the manual pusher can be used to bring the fixed rack horizontally close to the tipper gear ring position and roughly align it. If there is a deviation in the meshing between the fixed rack and the front (left) surface of the gear ring, the manual front (left) displacement scissor jack is used to push the fixed rack forward for adjustment. If there is a deviation in the meshing between the fixed rack and the rear (right) surface of the gear ring, the manual rear (right) displacement scissor jack is used to push the fixed rack backward (right) for adjustment. After the gear alignment is completed, the manual pusher is used to further push the rack to engage with the gear ring. If the tipper flips, it will drive the rack to move forward and backward (left and right) in the horizontal direction. Turn the front and rear (left and right) adjustment bolts to make close contact with the rack, so that the rack cannot move forward and backward (left and right). The vertical position fixed rack positioning platform is supported and cannot move downward, thereby locking the tipper end plate to prevent the tipper from rotating.

[0021] When the tipping machine is overhauled or needs to be started for flipping, the device to prevent uncontrolled rotation needs to be unlocked. Loosen the left and right (front and rear) adjustment bolts, move away from the fixed rack, and manually crank the pusher handwheel. The pusher top rod drives the rack to move to the right, and the fixed rack is disengaged from the gear ring. If the fixed rack is not in the middle position of the positioning platform after disengagement, if there is a deviation in the front, manually move the scissor jack forward to push the fixed rack to the right for adjustment. If there is a deviation in the back, manually move the scissor jack backward to push the fixed rack to the left for adjustment. When the fixed rack is roughly in the middle of the positioning platform, manually crank the pusher handwheel to continue to move the fixed rack to the right to return the fixed rack to its original safe position.

[0022] It meets the working requirements of preventing the tipping machine from rotating out of control at any angle, ensures the safe and reliable operation of the tipping machine system, is very convenient to use and simple to operate. Compared with other forms, it has many outstanding advantages, high promotion value and good market prospects.

[0023] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
