[0038] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0039] like Figures 1 to 8 As shown, the line-changing transport device of the horizontal casting production line includes a frame, a transfer trolley, a transfer carriage, a trolley drive mechanism, and a carriage drive mechanism. The frame is equipped with a production line track for the sand mold trolley to run on. The transfer carriage is mounted on the transfer trolley and can move along the production line axis. The transfer trolley is located at the end of the frame and can move along the direction perpendicular to the production line axis. The transfer carriage is equipped with carriage rails that can be connected to the production line track for the sand mold trolley to change lines and transfer. Both the trolley drive mechanism and the carriage drive mechanism are servo drive structures. The servo drive structures are associated with corresponding positions on the horizontal casting production line to ensure the smooth line-changing operation of the sand mold trolley and the sand mold it carries.

[0040] This utility model device also includes a controller 71 for controlling the line changing operation. The controller is connected to both the trolley drive mechanism and the auxiliary trolley drive mechanism. The control system enables linkage operation with the horizontal casting production line; that is, the servo-driven transfer trolley or transfer carriage of the line changing device is monitored by the controller and operates in linkage with the horizontal casting production line; the controller is equipped with a cable chain 73 and a protective cover 72.

[0041] The frame is equipped with a transversely arranged trolley rail 13 and a transmission rack 14; the transfer trolley is equipped with a trolley drive wheel that cooperates with the transmission rack, and the trolley drive mechanism is located on the transfer trolley and connected to the trolley drive wheel.

[0042] Furthermore, a trolley buffer limiting mechanism 15 for trolley buffering is provided on the frame and / or at the end of the trolley rail for trolley buffering. The trolley buffer limiting mechanism includes a fixed seat 153, an adjusting bolt 151, and a bumper 152 for buffering. The bumper is a rubber block and its position can be adjusted on the fixed seat by adjusting the bolt and locking nut 154, ensuring stable and reliable operation.

[0043] The lower part of the transfer trolley is equipped with an anti-deviation wheel assembly 26, which includes a pair of anti-deviation wheels 262. The anti-deviation wheels are mounted on the trolley body through anti-deviation wheel seats 261. The trolley rail is located between the pair of anti-deviation wheels. Each anti-deviation wheel is in contact with the corresponding side of the trolley rail, ensuring stable and reliable long-term operation.

[0044] The trolley drive mechanism includes a trolley driver, as well as a matching sprocket and transmission chain. The trolley driver and sprocket are both located on the transfer trolley, and the transmission chain is connected to the transfer trolley. The trolley driver is a servo motor, and the drive structure is integrated, making it stable and reliable.

[0045] The frame and / or production line track are equipped with a sand mold trolley anti-reverse mechanism to prevent the sand mold trolley from reversing. Preferably, the sand mold trolley anti-reverse mechanism includes a support and a stop, and the stop is provided on the support so that it can only rotate within a certain angle range in one direction.

[0046] A sand mold trolley reversing mechanism for defining the position of the sand mold trolley is provided on the frame and / or the production line track. Preferably, the sand mold trolley reversing mechanism includes a reversing cylinder and a claw. One end of the reversing cylinder is hinged to a rear support 852 provided on the production line track, the lower end of the claw is hinged to a front support 851 provided on the production line track, and the piston rod at the other end of the reversing cylinder is hinged to the upper part of the claw.

[0047] The line-changing conveyor device of this utility model for horizontal casting production line has a reasonable structural design, which enables the horizontal casting production line to operate stably and accurately for a long time, and avoids environmental pollution caused by hydraulic oil leakage during the production process. This line-changing conveyor device promotes the high efficiency and low failure rate of the horizontal casting production line, and effectively meets the production requirements of the casting industry.

[0048] The preferred specific example of this utility model is as follows:

[0049] The servo-driven line-changing conveyor is a component of the horizontal casting production line and is associated with it. The horizontal flaskless casting production line has a track line 81 for multiple sand mold trolleys 83 to circulate; the track lines are arranged in pairs or more, and the track lines of the production line are supported and fixed by the production line track columns 82.

[0050] like Figure 2 , Figure 3As shown, tracks I 811 and II 812 of the horizontal casting production line are arranged side-by-side as one track line; tracks III 813 and IV 814 of the horizontal casting production line are arranged side-by-side as another track line. That is, the horizontal casting production line consists of two or more track lines arranged side-by-side. The trolley track of the servo-driven line-changing transport device is perpendicularly associated with the track line of the horizontal casting production line and fixedly positioned, thus achieving connection or disconnection between the trolley track 23 of the servo-driven line-changing transport device and the track line. The servo-driven line-changing transport device is located at the end of the track line; or the servo-driven line-changing transport device is associated with a designated position on the track line.

[0051] The track line is used for the operation of the sand mold trolley 83; the sand mold trolley is used to carry the casting sand mold 86; the sand mold trolley includes a sand mold trolley body 831, which is a flat plate structure, and sand mold trolley wheels 832 are set under the sand mold trolley body through the sand mold trolley wheel axle 833; the track line 81 of the horizontal flaskless casting production line is connected by a servo-driven line changing and transport device, and the track line 81 of the horizontal flaskless casting production line realizes continuous casting production through the cyclic operation of the sand mold trolley 83.

[0052] like Figure 2 As shown, the sand mold trolley 83 travels from track III 813 and track IV 814 to the servo-driven line-changing transport device, and then from track I 811 and track II 812 onto track line 81 for cyclical operation; as... Figure 3 As shown, the sand mold trolley 83 travels from track I 811 and track II 812 to the servo-driven line-changing transport device, and then from track III 813 and track IV 814 onto track line 81 for cyclical operation.

[0053] like Figure 2 , Figure 3 The diagram illustrates one method of associating the servo-driven line-changing conveyor with the horizontal casting production line. The servo-driven line-changing conveyor is associated with the end of the track line in the horizontal casting production line. Other association configurations can also be implemented based on actual production conditions.

[0054] To ensure precise positioning of the sand mold trolley on track 81, prevent the sand mold trolley 83 from reversing and affecting the normal production of the horizontal casting production line, and to ensure the normal operation of the servo-driven line-changing transport device, a sand mold trolley anti-reverse mechanism 84 is provided below track I 811 and track II 812.

[0055] like Figure 6 As shown, the anti-reverse mechanism 84 of the sand casting trolley mainly consists of a support 841 and a stop block 842. The stop block 842 can only rotate within a certain angle range in one direction, and it automatically resets under its own weight when not under force.

[0056] Combination Figure 7 and Figure 2 or combination Figure 7 and Figure 3 As shown, when the sand mold trolley 83 passes the sand mold trolley reversing mechanism 85 while running on the track line 81, the reversing cylinder 853 of the sand mold trolley reversing mechanism is opened, causing the claw 854 to rotate to the right. When the claw 854 rotates, its height is reduced to below the lower part of the sand mold trolley 83, so as to ensure that the sand mold trolley 83 can pass smoothly above the sand mold trolley reversing mechanism 85.

[0057] Combination Figure 7 and Figure 2 or combination Figure 7 and Figure 3 As shown, the trolley rail 23 of the servo-driven line-changing transport device is connected to rails III 813 and IV 814. When the trolley 2 of the servo-driven line-changing transport device is unloaded, the sand mold trolleys 83 on rails III 813 and IV 814 are transported onto the trolley 2. At this time, in order to prevent the subsequent sand mold trolleys 83 on rails III 813 and IV 814 from partially leaving rails III 813 and IV 814 and hindering the normal operation of the servo-driven line-changing transport device and the horizontal casting production line, the sand mold trolley reversing mechanism 85 is activated. The reversing cylinder 853 drives the pawl 854 to rotate to the left. When the pawl 854 rotates, it is raised to block the subsequent sand mold trolleys 83 from continuing to run and accurately stop them at the set position, so as to ensure the normal operation of the horizontal casting production line and the servo-driven line-changing transport device.

[0058] The transfer trolley 2 mainly consists of a trolley body 21, trolley wheel sets 22, trolley rails 23, trolley drive unit mounting base 25, and trolley drive unit mounting base 28; driven wheel seats 56 are connected to the transfer trolley. The transfer trolley 2 runs on the trolley rails 13 via the trolley wheel sets 22. The trolley wheel sets 22 consist of trolley wheel axles 222 and trolley rollers 221, and are fixedly mounted under the transfer trolley.

[0059] The transfer trolley 2 is equipped with a trolley anti-deviation wheel assembly 26 consisting of an anti-deviation wheel seat 261 and an anti-deviation wheel 262. The anti-deviation wheel 262 of the anti-deviation wheel assembly 26 makes rolling contact with the side of the trolley rail to prevent the trolley wheel assembly 22 from deviating or detaching from the trolley rail.

[0060] The transfer trolley is also equipped with a trolley guiding mechanism 27 to further ensure the smooth operation of the trolley 2. The trolley guiding mechanism 27 consists of a guide wheel assembly 271, a guide wheel seat 272, a guide rail 273, and a guide rail support column 274. The guide wheel seat 272 of the trolley guiding mechanism is connected to the frame platform 12 on the trolley via the guide rail support column 274, connecting fixing seat I 16, and connecting fixing seat II 17; the frame platform is supported and fixed by a set of support columns 11.

[0061] The transfer trolley 2 is equipped with a set of parallel trolley rail fixing seats 24 to fix a set of parallel trolley rails 23 for the transfer trolley 3 and sand mold trolley 83 to run back and forth.

[0062] The transport vehicle is equipped with a trolley driver mounting bracket 25 and a trolley driver mounting bracket 28. The trolley driver mounting bracket 25 is used to mount and fix the trolley driver 41; the trolley driver mounting bracket 28 is used to mount and fix the trolley driver 51.

[0063] Both the trolley driver 41 and the trolley driver 51 are servo motor drive structures. The trolley driver 41 and the trolley driver 51 work in conjunction with the horizontal casting production line through the control system. Their linear running accuracy can reach 0.1mm, which fully meets the accuracy requirements for the normal operation of the horizontal casting production line.

[0064] Under the action of the trolley driver 41, the trolley drive wheel 42 meshes with the transmission rack 14 to drive the trolley to move back and forth.

[0065] like Figure 2 , Figure 3 As shown, when the trolley runs to the positions of track I 811 and track II 812, the trolley rail 23 is connected to track I 811 and track II 812 respectively, so that the sand mold trolley 83 on track line 81 is sent to the trolley rail 23 of the trolley; when the trolley runs to the positions of track III 813 and track IV 814, the trolley rail 23 is connected to track III 813 and track IV 814 respectively, and the sand mold trolley 83 on the trolley leaves and is sent to track line 81.

[0066] like Figure 2 , Figure 3 As shown, the servo-driven line-changing transport device's transfer trolley carries the sand mold trolley 83 on track 81 and moves to track I 811 and track II 812. The trolley rail 23 connects to track I 811 and track II 812. The trolley driver 51 then drives the sand mold trolley 83 off the trolley and onto track 81. The servo-driven line-changing transport device's trolley then runs unloaded to track III 813 and track IV 814, where the trolley rail 23 connects to track III 813 and track IV 814. The sand mold trolley 83 on track 81 of the horizontal casting production line is then loaded onto the servo-driven line-changing transport device's trolley.

[0067] Next, the servo-driven line-changing transport device carries the sand mold trolley 83 to track III 813 and track IV 814, pushing the sand mold trolley 83 onto track line 81; this process is repeated.

[0068] It is evident that the servo-driven line-changing transport device works in conjunction with the horizontal casting production line under the control of the control system. The trolley driver 41 operates, driving the transfer trolley to travel back and forth and connect with the track line 81; when the trolley track 23 connects with the track line 81, under the linkage of the trolley driver 51 and the horizontal casting production line, the sand mold trolley 83 completes the line-changing operation between different groups of track lines 81 of the horizontal casting production line by being carried and transported by the trolley.

[0069] like Figure 2 , Figure 3 In this system, the trolley driver 41 and the trolley driver 51 operate independently. That is, when the trolley driver 41 is working, the trolley driver 51 stops working, or when the trolley driver 51 is working, the trolley driver 41 stops working.

[0070] The transfer trolley 3 consists of a trolley body 31, trolley rollers 32, trolley guide wheels 33, a front end fixing seat of the transmission chain 34, and a rear end fixing seat of the transmission chain 35.

[0071] The transfer trolley 3 moves back and forth on the trolley rail 23 of the main trolley via trolley rollers 32 located below the trolley body 31. The transfer trolley 3 uses guide wheels 33 to roll against the side of the trolley rail 23 to prevent horizontal deviation or derailment. The transfer trolley 3 is connected to the transmission chain 55 in a ring via a front-end fixed seat 34 and a rear-end fixed seat 35. Driven by the trolley driver 51, the trolley 3 is propelled to reciprocate via the driven wheel 57 on the driven wheel seat 56, the driving wheel 54, and the transmission chain 55.

[0072] The transfer trolley 3 is driven by a trolley drive mechanism. The trolley drive mechanism mainly consists of a trolley driver 51, a drive wheel axle seat 52, a drive wheel axle 53, a drive wheel 54, a transmission chain 55, a driven wheel seat 56, and a driven wheel 57, forming a ring-shaped traction chain; a protective cover 58 is provided for the corresponding transmission chain.

[0073] from Figure 2 , Figure 3 It can be seen that when the trolley rail 23 is connected to rails III 813 and IV 814, the trolley driver 51 and the horizontal casting production line work together, and the transfer trolley 3 moves away from rails III 813 and IV 814. At this time, during the operation of the trolley, the sand mold trolley 83 on rails III 813 and IV 814 is sent to the trolley rail 23 of the main trolley. Obviously, when the trolley rail 23 is connected to rails I 811 and II 812, the trolley driver 51 works, and the transfer trolley 3 moves towards rails I 811 and II 812. Through the rear fixed seat 35 of the transmission chain, it drives the sand mold trolley 83 on the main trolley to move towards the track line 81 until the sand mold trolley 83 is sent into rails I 811 and II 812.

[0074] After the trolley rail 23 is connected to rail I 811 and rail II 812, the trolley driver 51 works, and the transfer trolley 3 moves in the direction of rail I 811 and rail II 812. At the same time, it drives the sand mold trolley 83 on the transfer trolley 2 to leave through the fixed seat 35 at the rear end of the transmission chain.

[0075] like Figure 5 As shown, a trolley balance protection mechanism is further provided at the end of the transfer trolley 3 to ensure the smooth operation of the trolley and prevent vertical derailment during the operation of the trolley.

[0076] The trolley balancing and protection mechanism consists of a balance wheel bracket 61, a balance wheel 62, a balance track post 63, and a balance track 64. The balance wheel bracket 61 is mounted on the trolley, and the balance wheel 62 is located at one end of the balance wheel bracket 61; the balance wheel 62 is in contact with the balance track 64; the balance track 64 is fixed by the balance track post 63. The trolley balancing and protection mechanism is associated and fixed to the frame of the servo-driven line-changing and transporting device.

[0077] like Figure 2 , Figure 3 The servo-driven line-changing conveyor shown is arranged at one end of the track of the horizontal casting production line. The servo-driven line-changing conveyor is associated with and positioned on the horizontal casting production line, meaning it can be positioned at the end of the track or a designated location on the track according to the horizontal casting production line.

[0078] In addition, scraper plates 263 are installed between the trolley and the anti-deviation wheel seat and at the corresponding positions of the trolley and the trolley rail to effectively remove sand and dust from the trolley rail and the trolley rail on the servo-driven line-changing transport device, so as to prevent sand and dust from hindering the operation of the trolley or the trolley and to ensure the stable operation of the horizontal casting production line.

[0079] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0080] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
