[0019] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0020] Those skilled in the art should understand that, in the disclosure of the specification, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0021] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0022] refer to Figure 1 and Figure 2 The present invention provides a pig gate pushing device, including a mobile frame 10. The mobile frame 10 includes mounting bases 20 symmetrically arranged on both sides of the pig driving passage, a mobile frame 30 arranged on the mounting bases 20, and a support frame 40 connected between the mobile frames 30 on both sides. A rotating element 31 is installed on each of the mobile frames 30 on either side. The mobile frame 30 on which the rotating element 31 is installed is defined as a mounting frame 300.

[0023] A fixed chain 51 is provided on the mounting base 20 near the mounting frame 300 along the extension direction of the pig-driving passage. In other words, the fixed chain 51 is fixedly mounted on the mounting base 20 rather than a conventional closed-loop rotating chain. In addition, the extension direction of the fixed chain 51 is consistent with the extension direction of the pig-driving passage.

[0024] A driving sprocket 32 ​​is coaxially mounted on the rotating end of the rotating element 31, and the driving sprocket 32 ​​is in transmission cooperation with the fixed chain 51, so that when the rotating element 31 is in operation, the movable frame 10 can be driven to move along the pig-driving passage as a whole based on the transmission cooperation relationship, wherein the transmission cooperation relationship is the meshing relationship between the gear teeth and the chain;

[0025] A telescopic element 41 is installed on the top of the support frame 40, wherein the telescopic element 41 extends in the vertical direction, and the telescopic end at the bottom of the telescopic element 41 is connected to a push plate 42, and the push plate 42 cooperates with the pig-driving channel to realize the lifting or lowering of the push plate 42.

[0026] Specifically, in the process of driving the pigs to move in the pig driving channel, after the pigs enter the driving position and complete the entry, the telescopic element 41 drives the push plate 42 to descend, and then the rotating element 31 runs. Under the transmission cooperation of the active sprocket 32 ​​and the fixed chain 51, the moving frame 10 as a whole moves in a direction along the fixed chain 51, that is, it moves along the extension direction of the pig driving channel, and cooperates with the push plate 42 to realize the pig driving behavior, and drive the pigs to the designated position in the pig driving channel. Then the telescopic element 41 lifts the push plate 42, and returns to the initial position under the action of the rotating element 31, ready to drive the next batch of pigs.

[0027] In one embodiment, the rotating element 31 is a rotating motor, such as a servo motor.

[0028] In one embodiment, the telescopic element 41 is a cylinder.

[0029] In one embodiment, guide rails 21 are provided on the top of the mounting bases 20 on both sides along the extension direction of the pig-driving passage, and the movable frame 30 is provided with a slide groove 301 that slides with the guide rail 21, thereby ensuring the overall movement stability of the movable frame 10, that is, the stability of the pig-driving operation, through the sliding fit relationship between the guide rail 21 and the slide groove 301.

[0030] Further preferably, a tensioning wheel 33 is installed on the mounting frame 300, and in the extension direction of the pig-driving channel, the tensioning wheels 33 are distributed on both sides of the driving sprocket 32 ​​and mesh with the fixed chain 51 through gear teeth. At the same time, the tensioning wheels 33 and the driving sprocket 32 ​​on both sides are respectively located on both sides of the fixed chain 51, that is, a triangular matching relationship is formed by two tensioning wheels 33 and one driving sprocket 32. During the transmission process, it can be ensured that the driving sprocket 32 ​​is not easily separated from the fixed chain, thereby ensuring the stability of the transmission, that is, the stability of the movement of the mobile frame 10. During the movement process, the relative positional relationship between the tensioning wheel 33 and the driving sprocket 32 ​​does not change. The driving sprocket 32 ​​rotates actively, and the tensioning wheel 33 rotates passively, driving the entire mobile frame 10 to move in a directional manner on the fixed chain 51.

[0031] Considering that in some cases the matching relationship between the driving sprocket 32 ​​and the fixed chain 51 may become loose, even if there is a triangular matching relationship between the tensioning wheel 33 and the driving sprocket 32, there is still a problem of reduced transmission accuracy during the transmission process, which may cause transmission failure in severe cases.

[0032] Therefore, it is further preferred that the mounting frame 300 is provided with a fixing seat 34 for mounting the tensioning wheel 33, and the axle of the tensioning wheel 33 is mounted in the fixing seat 34 through a bearing seat, and the fixing seat 34 is provided with a tightening bolt 35 at the top and bottom facing the bearing seat, so that the height position of the tensioning wheel 33 can be adjusted by cooperating with the upper and lower tightening bolts 35, and the fixed chain 51 can be further tightened when the matching relationship between the driving sprocket 32 ​​and the fixed chain 51 becomes loose, which can effectively ensure the matching accuracy between the driving sprocket 32 ​​and the fixed chain 51, and thus ensure the transmission accuracy between the two, wherein the height position of only one of the tensioning wheels 33 can be adjusted, or the height positions of the two tensioning wheels 33 can be adjusted at the same time, and the adjustment is convenient and easy to maintain;

[0033] In addition, the upper and lower parts are adjusted on both sides of the bearing seat through two tightening bolts 35. After adjustment, the bearing seat can be ensured to maintain the same posture, with only the height changing. At the same time, the stability of the bearing seat after adjustment can be ensured, that is, the stability of the tensioning wheel 33 is always ensured.

[0034] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are provided for illustrative purposes only and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
