Description

Technical Field

[0001] The utility model relates to the field of scraper machine technical connections, in particular to a transition trough connector. Background Art

[0002] The scraper conveyor transition trough is an important component of the coal mine scraper conveyor. Its main function is to connect the head frame and the middle trough, adjust the height difference between them, and ensure the smooth transition of the scraper chain from the middle trough to the head. The existing transition trough connector is an integrated structure made of thick steel plate. During the workshop production process, workers use flame cutting to cut the outer contour of the connector according to the production process in the blanking workshop. Then, the robot cuts the welding groove. Then it is transferred to the machining workshop. The CNC boring and milling machine operator processes the transition dumbbell pin connection groove according to the drawing dimensions. After the processing is completed, it is transferred to the riveting and welding workshop for the overall assembly and welding of the transition trough. This type of middle trough is complex to process and has a long production cycle, which seriously affects production efficiency and puts great pressure on the production schedule. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a transition groove connector, which is formed by welding a body with a groove and a plug that matches the shape of the groove to form a transition groove connector. This assembly can greatly shorten the processing cycle and reduce the labor intensity of workers.

[0004] To achieve the above purpose, the utility model adopts the following technical solution: a transition groove connector, including a body, a groove opened up and down through the body, and a plug adapted to the groove; the plug is located inside the groove and welded to the inner wall of the groove.

[0005] Furthermore, the cross section of the body is a right-angled trapezoid, and the inclined side edges of the body are provided with grooves.

[0006] Furthermore, the notch includes a first groove and a second groove respectively arranged close to the upper base and the lower base of the right-angled trapezoid; the first groove and the second groove are arranged opposite to each other.

[0007] Furthermore, there are two first grooves and two second grooves, and both the first grooves and the second grooves pass through the corresponding bottom edges in the horizontal direction.

[0008] Furthermore, the thickness of the plug is smaller than the thickness of the body, and the bottom surface of the plug is flush with the bottom surface of the body.

[0009] Furthermore, the plug includes a first plug welded inside the first groove and a second plug welded inside the second groove, and the upper surface edge and the lower surface edge of the second plug are both chamfered.

[0010] The beneficial effect of the present invention is that the present invention forms a transition groove connector by welding the body with a slotted body and a plug that matches the shape of the slot. This assembly can greatly shorten the processing cycle and reduce the labor intensity of workers. The optimized and improved transition groove connector is obtained by directly assembling and welding three parts after cutting, which eliminates the machining process, makes it easier to ensure the processing quality, and plays a vital role in ensuring the quality and quantity of the project schedule.

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0019] Example:

[0020] like Figures 1-6 As shown, a transition groove connector includes a body 1, a groove opened through the body 1 from top to bottom, and a plug adapted to the shape of the groove; the plug is located inside the groove and welded to the inner wall of the groove.

[0021] The cross section of the body 1 is a right-angled trapezoid, and the inclined side edges of the body 1 are provided with grooves 4, which are provided on all four sides.

[0022] The notch includes a first groove 2 and a second groove 3 respectively arranged near the upper base and lower base of the right-angled trapezoid; the first groove 2 and the second groove 3 are arranged opposite to each other, and the center lines of the two are on the same straight line; the first groove 2 is T-shaped, and the second groove 3 is semi-elliptical.

[0023] There are two first grooves 2 and two second grooves 3, and both first grooves 2 and second grooves 3 pass through the base of the corresponding right-angled trapezoid in the horizontal direction, that is, the base they are close to. The first groove 2 corresponds to the longer base, and the second groove 3 corresponds to the shorter base.

[0024] The thickness of the plug is smaller than that of the body 1 , and the bottom surface of the plug is flush with the bottom surface of the body 1 . The plug is made of 25mm Q355 steel plate, and the body 1 is made of 80mm Q355 steel plate.

[0025] The plug includes a first plug 6 welded inside the first groove 2 and a second plug 7 welded inside the second groove 3. The upper surface edge and the lower surface edge of the second plug 7 are both chamfered; the first groove 2 and the second groove 3 are connected through a horizontally arranged through hole 5.

[0026] Due to the limited accuracy of flame cutting, the groove cannot be cut directly, and workers need to cut it out bit by bit; when this solution is working, a through groove can be opened directly in the cutting step, and then the groove 4 is processed, and then the plug and the groove are welded to complete it. Compared with the existing manufacturing method that requires CNC boring and milling machine operators to process the groove bit by bit according to the drawing size, this solution only requires workers to complete the welding of the plug and the body 1; the component transition groove connector used in this solution is mainly able to greatly shorten the construction period compared to the traditional one-piece transition groove connector; it takes less than an hour to weld a transition groove connector of this solution, while the transition groove connector using the traditional structure requires a whole day to manufacture.

[0027] By passing through the body with the slot and the plug that matches the shape of the slot, the body and the plug are welded to form a transition groove connector. This assembly can greatly shorten the processing cycle and reduce the labor intensity of workers. The optimized and improved transition groove connector is obtained by directly assembling and welding three parts after cutting, eliminating the machining process, making it easier to ensure the processing quality, and also playing a vital role in ensuring the quality and quantity of the project schedule.

[0028] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
