Description

Technical Field

[0001] This utility model relates to the field of coke pusher cars, specifically to a quick-change device for the coke pusher rod slide shoe of a coke pusher car. Background Technology

[0002] Coking, as a link in coal production and processing, plays a role in differentiating the various products in coal. In existing coking production, a special coking pusher is needed to push the red coke out of the carbonization chamber. To ensure the stability of the pusher during operation, corresponding slippers are usually installed below it to prevent shaking or deviation caused by uneven or tilted tracks. However, with the continuous friction between the slippers and the coke, the slippers inevitably experience hard wear, thereby reducing their effectiveness. Therefore, the slippers need to be designed to ensure quick replacement.

[0003] Existing push rods are usually connected to the slide shoe via an inverted triangular bracket. The lower part of the inverted triangular bracket has an adjustment groove for fixing the slide shoe, which ensures stable operation of the slide shoe and facilitates adjustment of the slide shoe angle. The side wall of the adjustment groove is mostly connected to the slide shoe using pins.

[0004] While this connection structure facilitates the assembly of the skis, it makes it difficult to quickly position the pins when calibrating the pin holes. The position of the pins needs to be adjusted manually repeatedly. Furthermore, due to the weight of the skis, this makes calibration extremely physically demanding. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing quick-change devices for the coke pusher rod slide shoe on coke pusher cars are difficult to quickly calibrate the pin hole position of the inverted triangular bracket and the slide shoe.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a quick-change device for the sliding shoe of the coking pusher rod of a coking pusher, including an inverted triangular bracket fixed below the coking pusher rod and a sliding shoe connected to the inverted triangular bracket by a pin. The bottom surface of the inverted triangular bracket is provided with an adjustment groove for fixing the sliding shoe. The two side walls of the adjustment groove of the inverted triangular bracket are provided with longitudinal ear plates and transverse ear plates with positioning pin holes for positioning the sliding shoe. The opening of the transverse ear plate is provided with a positioning rod with pin holes at both ends. The left and right sides of the sliding shoe are provided with positioning grooves corresponding to the positioning rods. The left and right sides of the sliding shoe are sloped surfaces. The longitudinal ear plates and transverse ear plates are both connected to the pin holes on both sides of the positioning rod by pin rods.

[0007] As an improvement, the opening end of the positioning groove is provided with a V-shaped slope to facilitate the sliding of the positioning rod.

[0008] As an improvement, the bottom surface of the pin hole of the longitudinal ear plate and the transverse ear plate is provided with a nut, and the bottom surface of the pin rod is welded with an external hexagonal screw.

[0009] As an improvement, the inverted triangular bracket is connected to the coke pusher rod by a bolt structure.

[0010] As an improvement, a shock-absorbing pad is attached to the inner wall of the positioning groove.

[0011] As an improvement, a pressure-resistant bearing is fitted onto the connecting pin between the inverted triangular bracket and the slipper.

[0012] The advantages of this invention compared to the prior art are as follows: This device determines the direction of the sliding shoe by adjusting the groove and the side slope of the sliding shoe, and then quickly positions the pin hole of the inverted triangular bracket and the sliding shoe by sliding the positioning rod and the positioning groove. After calibrating the pin hole position, a pin is inserted for positioning, and then the positioning rod is rotated to slide into the longitudinal ear plate for fixation, thereby ensuring the angle adjustment of the sliding shoe during operation. Compared with the prior art, this device can directly complete the positioning of the pin hole without manual calibration. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] As per the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, in order to ensure the stability of the coke pusher rod during operation, an inverted triangular bracket 1 is usually installed below the coke pusher rod using bolts, and a sliding shoe 2 is installed below the inverted triangular bracket 1 using pins. In order to ensure the stability during operation, the bottom surface of the inverted triangular bracket 1 is provided with an adjustment groove 11 for fixing the sliding shoe 2.

[0020] To facilitate the replacement of the slipper 2, the two side walls of the adjustment groove 11 of the inverted triangular bracket 1 are provided with longitudinal ear plates 3 and transverse ear plates 31 for positioning the slipper 2 pin holes. The opening of the transverse ear plate 31 is provided with a positioning rod 4 with pin holes at both ends. The left and right sides of the slipper 2 are provided with positioning grooves 41 corresponding to the positioning rods 4. In order to ensure that the slipper 2 can slide smoothly into the adjustment groove 11, the left and right sides of the slipper 2 are sloped surfaces, and the opening end of the positioning groove 41 is provided with a V-shaped slope to facilitate the sliding of the positioning rod 4. The longitudinal ear plate 3 and the transverse ear plate 31 are connected to the pin holes on both sides of the positioning rod 4 through the pin rod 5.

[0021] To ensure the stability of the pin rod 5 inserted into the pin holes of the longitudinal ear plate 3, the transverse ear plate 31 and the positioning rod 4, the bottom surface of the pin holes of the longitudinal ear plate 3 and the transverse ear plate 31 is provided with a nut 6, and the bottom surface of the pin rod 5 is welded with an external hexagonal screw 61.

[0022] To ensure that the positioning rod 4 will not be damaged when it contacts the inner wall of the positioning groove 41, a shock-absorbing pad is attached to the inner wall of the positioning groove 41. Similarly, to ensure that the sliding shoe 2 will not rub hard against the pin when it changes its angle, a pressure-resistant bearing is fitted on the connecting pin of the inverted triangular bracket 1 and the sliding shoe 2.

[0023] In the specific implementation of this utility model, the connecting pin between the inverted triangular bracket 1 and the slide shoe 2 is pulled out, the new slide shoe 2 is placed on the track for the push rod to advance, and then the push rod is activated to disengage the old slide shoe 2. After disengagement, the external hexagonal screw 61 at the outer end of the longitudinal ear plate 3 is pulled out, and the positioning rod 4 in the longitudinal ear plate 3 is rotated to lock it in the transverse ear plate 31. The external hexagonal screw 61 is then screwed into the screw hole below the transverse ear plate 31 for fixation. When the new slide shoe 2 slides into the adjustment groove 11, the positioning groove 41 on the side of the new slide shoe 2 will engage with the positioning rod 4 at the rear. After engagement, the new slide shoe 2 will slide synchronously with the push rod, and at this moment, the pin holes of the inverted triangular bracket 1 and the slide shoe 2 are aligned. Finally, the pin is inserted for fixation.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
