Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, and in particular to a trolley traction device for a waste incinerator pusher. Background Technology

[0002] The long-term stable operation of waste-to-energy plants is a key factor in maximizing the plant's operational efficiency. A waste incinerator system consists of three main parts: a feeding system, a grate system, and a ash removal system. Stable feeding by the feeding system is crucial for ensuring the long-term stable operation of the waste incinerator. The core equipment of the feeding system is the pusher, which contains multiple sets of pushing trolleys. The pusher continuously and evenly pushes the waste into the incinerator furnace.

[0003] The pusher trolley is powered by a hydraulic cylinder. Due to the variable composition of waste, when large pieces of waste clog the pusher outlet, the pushing resistance on the trolley increases. When the resistance exceeds the thrust provided by the hydraulic cylinder, the trolley will jam forward. Similarly, during the trolley's retraction, jamming can also occur due to resistance exceeding the cylinder's maximum pulling force. When the pusher trolley jams, it may require manual on-site handling (i.e., maintenance personnel use jacks (for forward jamming) or chain hoists (for retraction jamming) to apply external force), or in severe cases, it can lead to a shutdown, seriously affecting the stable operation of waste incineration. Manual handling of a jammed pusher trolley is inconvenient, and the jamming is random, requiring maintenance personnel to be constantly prepared, wasting significant manpower and impacting the stable operation of the incinerator. Utility Model Content

[0004] To address the issue of jamming during the forward or backward movement of the material pusher trolley and to prevent shutdown accidents in waste incinerators caused by the jamming of the material pusher trolley, this utility model provides a material pusher trolley towing and traction device for waste incinerator material pushers.

[0005] To address the aforementioned technical problems, this application provides the following technical solution:

[0006] A traction device for a feeder trolley in a waste incinerator includes trolley pull rings located on both sides of the rear of the feeder trolley. The pull rings of two adjacent feeder trolleys are connected by a trolley pull rod. The front end of the pull ring is connected to the feeder trolley, and a circular pull rod mounting hole is provided in the center of its rear. The trolley pull rod includes a retaining plate and a pull rod. The pull rod is inverted U-shaped, and both ends of the pull rod pass through the through holes at both ends of the retaining plate and are inserted into the pull rod mounting holes in the pull rings of the two adjacent feeder trolleys.

[0007] The diameter of the pull rod is smaller than the diameter of the pull rod mounting hole.

[0008] The pusher trolley is equipped with wheels at the bottom and is connected to a hydraulic cylinder at the front center via a pin. The pusher trolley can reciprocate along the track by being pushed by the hydraulic cylinder.

[0009] The card plate is oblong in shape.

[0010] Compared with the prior art, the trolley traction device of the waste incinerator pusher of this utility model has at least the following beneficial effects:

[0011] The present invention relates to a trolley traction device for a waste incinerator feeder. This device can make full use of the surplus thrust or pull of adjacent feeder trolleys. Through the mutual traction between adjacent feeder trolleys, it can effectively reduce the probability of the feeder trolleys getting stuck in the incinerator feeding system and avoid losses due to incinerator shutdown.

[0012] The following description, in conjunction with the accompanying drawings, further illustrates the trolley-pulling device for the feeder of this waste incinerator. Attached Figure Description

[0019] like Figure 1-3As shown, a trolley traction device for a waste incinerator pusher includes trolley pull rings 4 located on both sides of the rear of the pusher trolley 1. The trolley pull rings 4 of two adjacent pusher trolleys 1 are connected by trolley pull rods 5. The front end of the trolley pull ring 4 is connected to the pusher trolley 1, and its rear is circular. A circular pull rod mounting hole 401 is provided in the center of the rear. The trolley pull rod 5 includes a retaining plate 501 and a pull rod 502. The pull rod 502 is inverted U-shaped. The two ends of the pull rod 502 pass through the through holes at both ends of the retaining plate 501 and are inserted into the pull rod mounting holes 401 in the trolley pull rings 4 of the two adjacent pusher trolleys 1.

[0020] The bottom of the pusher trolley 1 is equipped with traveling wheels 7. The front center of the pusher trolley 1 is connected to the hydraulic cylinder 3 via a pin 2. The pusher trolley 1 can reciprocate along the track 6 by being pushed by the hydraulic cylinder 3. There are at least two pusher trolleys 1, which are arranged side by side.

[0021] The clamping plate 501 is oblong. The clamping plate 501 can increase the overall strength of the trolley pull rod 5 and also position the depth at which the pull rod 502 is inserted into the trolley pull ring 4.

[0022] like Figure 4-5 As shown, the distance between the centers of the two ends of the pull rod 502 is W, and the diameter d of the pull rod 502 is smaller than the diameter D of the pull rod mounting hole 401. When the pusher trolley jams, the pull rod is in a taut state, as shown. Figure 4 As shown, at this time, the lateral distance between the centers of the tie rod mounting holes of two adjacent pusher trolleys is L, the longitudinal distance is b, and the straight distance is C.

[0023] Since d < D, when the displacement difference between adjacent pusher trolleys is less than L, the trolley tie rod 5 is not tightened, and no dragging force occurs between adjacent trolleys. When a pusher trolley 1 gets stuck, the trolley tie rod 5 is tightened, and the adjacent pusher trolley 1 will drag the stuck pusher trolley 2 through the trolley tie rod 5, applying the excess thrust or pull force of the hydraulic cylinder of the pusher trolley that meets the requirements for normal movement to the stuck pusher trolley, thereby avoiding the occurrence of pusher trolley jamming.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
