Description

Technical Field

[0001] This utility model relates to the field of RGV transfer technology, and in particular to a multifunctional RGV for transporting materials to and from the furnace opening. Background Technology

[0002] In the boiler factory sector, it is necessary to transport materials to different boilers. Especially in small factory areas, there are often two sets of opposing boilers set up opposite each other. In order to solve the problem of boiler feeding, RGV trolleys are needed to transfer materials within the site.

[0003] The problem is that, 1) due to the small distance between the two boilers in the site, the RGV trolley in the site cannot turn around in place, so multiple units need to be equipped to cooperate in the transfer.

[0004] 2) The presence of multiple slopes on the site makes it inconvenient for the existing RGV carts to move. For example, if one RGV cart is used to transport materials under the same slope, the cart is not suitable for use across sites with different slopes, which increases the number of carts required.

[0005] 3) When the trolley is transported to the furnace mouth, since the trolley does not have the function of receiving and feeding materials, a special person needs to be assigned to unload the material onto the conveyor roller line when it travels to the furnace mouth to complete the feeding, which is inefficient. Utility Model Content

[0006] This application addresses the shortcomings of the prior art by providing a multi-functional RGV for transporting materials to opposing furnace openings. Functionally, it integrates three major design features: precise 90-degree rotation, secondary lifting and feeding, and an anti-slope vehicle body. It can transfer materials in the narrow and short-stroke area of ​​opposing boiler sites, avoiding the drawbacks of the prior art that requires multiple RGVs, independent trolleys for each slope, and dedicated personnel for unloading.

[0007] The technical solution adopted in this utility model is as follows:

Each set of rotating assemblies includes a hinge support disposed on the middle frame and a hinge head disposed on the adjacent frame. The hinge head and the hinge support are rotatably connected by a rotating shaft.

[0010] Furthermore, both the front frame and the rear frame are equipped with two sets of driven wheel sets, and both ends of the mid-frame are equipped with two sets of wheel sets. One set of wheel sets in the mid-frame is a driven wheel set, and the other set is a driving wheel set. The driving wheel sets transmit torque through a coupling and a drive shaft. The drive assembly includes a motor mount mounted on the mid-frame frame, a main servo motor fixed on the motor mount, a driving sprocket mounted on the drive end of the main servo motor, and a driven sprocket mounted on the drive shaft. The driving sprocket and the driven sprocket are driven by a chain.

[0011] Furthermore, the rotating assembly includes a guide rail disposed on the upper surface of the frame body, a frame platform disposed on the guide rail, two sets of active drive components that travel along the guide rail connected to the front two sides of the frame platform, two sets of driven drive components that travel along the guide rail connected to the rear two sides of the frame platform, a main shaft disposed at the center of the frame body, and the center of the frame platform connected to the main shaft and rotating around the center through the active drive components.

[0012] Furthermore, each of the active drive components includes a first flange bracket connected to the rack platform, a main motor base connected to the end face of the first flange bracket, a first servo motor fixed to the outward end face of the main motor base, a first sprocket connected to the drive end of the first servo motor, a first rotating shaft disposed in the internal cavity of the main motor base, a second sprocket disposed on the first rotating shaft, the first sprocket and the second sprocket being connected by chain drive, and a drive wheel disposed on the coaxial of the second sprocket;

[0013] The driven component includes a second flange bracket connected to the rear end of the frame platform. A wheel seat is connected to the end face of the second flange bracket, and a driven wheel is disposed in the wheel seat via a rotating shaft.

[0014] Furthermore, a bearing seat is provided at the center of the main frame body, a bearing is provided inside the bearing seat, a main shaft is connected inside the bearing, and the upper end face of the bearing seat is a flange end face. Four sets of plug-in plates are inserted into each other on the flange end face, and a through square groove is formed between the opposite plug-in plates. The square groove is used to support and fix the frame platform.

[0015] The lower end face of the frame body is provided with a walking component for driving the frame body to move.

[0016] Two sets of limiting devices are also installed within the frame of the main body of the vehicle.

[0017] Furthermore, the material pushing mechanism includes a docking platform, a chain drive mechanism is provided at the center of the docking platform, and chute tracks are provided on both end faces of the docking platform.

[0021] The advantages of this utility model over the prior art are as follows:

[0022] 1) This utility model adopts a three-section frame structure. When driving, the double-sided anti-slope driven wheel sets corresponding to the front and rear frames first contact the bottom surface of the flat plate and the inclined surface of the slope rail when going uphill. When going downhill, due to gravity, one side of the two sides can touch the ground in time to ensure a smooth transition. Therefore, it is greatly adapted to the working conditions of the site with slope.

[0023] 2) This utility model adopts dual-motor dual-control rotation, with dual motors controlling the forward and backward movement simultaneously. After passing the angle, the limiting device performs precise limiting. Compared with the traditional hydraulic cylinder driven rotation, it can ignore the limitations of rotation angle and direction.

[0024] 3) This utility model provides a docking mechanism capable of extending and retracting two strokes without changing the original RGV trolley chassis length, thereby achieving a longer feeding distance. The docking mechanism includes a first feeding body and a second feeding body. The first feeding body is equipped with multiple double-wheel frames, each with two sets of vertically staggered guide wheels, allowing the first feeding body to slide and be guided within the chute track, and allowing the second feeding body to slide and be guided on the first feeding body. The first feeding body achieves a single feeding distance based on chain pushing; based on the first feeding body, the second feeding body achieves a secondary feeding distance based on hydraulic cylinder pushing, thus achieving a larger feeding distance in a compact structural design.

[0077] The specific structure and working principle of this utility model are as follows:

[0078] 1) Structure and principle of the three-section body assembly 100:

[0079] The main components include a front frame 11, a middle frame 12, and a rear frame 13. Two sets of driven wheel sets 14 are installed on the front frame 11 and the rear frame 13 for double-sided slope protection. One set of driven wheel sets 14 and one set of driving wheel sets 15 are installed on the middle frame 12.

The main servo motor 22 transmits torque to the driving wheel set 15 through the chain of the sprocket 91. When the railcar structure is in motion, the double-sided slope protection driven wheel sets 14 corresponding to the front and rear frames 13 first contact the bottom surface of the flat plate and the inclined surface of the slope rail when going uphill. When going downhill, due to gravity, one side of the two sides can touch the ground in time, ensuring a smooth transition. Therefore, it is greatly adapted to the working conditions of sloping sites.

[0080] 2) Structure and principle of rotating assembly 200:

[0081] It mainly includes a frame body 1, a guide rail 41, and a frame platform 42 rotatably mounted on the guide rail 41. The frame body 1 enables the vehicle to move forward, backward, left, and right through the walking component 74 on the lower end of the chassis. The specific structure of the walking component 74 will not be described in detail. It is the same as the traditional RGV. The frame platform 42 on the frame body 1 has a rotation center and rotation guides and drives located at both ends of the frame platform 42. The rotation center is located at the center of the frame body 1. It includes a bearing seat 71 and a main shaft 7 that is rotatably mounted through the bearing in the bearing seat 71. Four plug plates 72 are fixed upward on the bearing seat 71. Since the frame platform 42 is a long rectangle, the square groove 73 formed by the plug plates can support and accommodate the frame platform 42. The front and rear ends of the rack platform 42 are respectively provided with an active drive component 52 and a driven drive component 6, both of which provide guidance for the rack platform 42 to slide on the guide rail 41. The active drive component 52 uses the drive form of the first servo motor 52 to provide input driving force. The dual motors control the rotation, and the forward and backward movements are controlled by the dual motors at the same time. After passing the angle, the limit device 75 performs precise limit.

[0082] 3) Structure and principle of material pushing mechanism 300:

[0083] It mainly includes a docking platform 8, a chain set at the center of the docking platform 8, slide rails 10 set on both end faces of the docking platform 8, and a first pushing body 400 and a second pushing body 600 within the slide rails 10. Spatially, the first pushing body 400 is smaller than the inner diameter of the slide rail 10, and the second pushing body 600 is smaller than the inner diameter of the profile of the first pushing body 400, so that the second pushing body 600 and the first pushing body 400 are spatially combined. The lower part of the first pushing body 400 is hollow, and four sets of double wheel frames 402 are fixed between its profiles. The last one at the end of the figure is a single wheel frame. The upper part has two guide wheels, which are staggered and are designated as upper guide wheel 403 and lower guide wheel 404. The upper guide wheel 403 provides support and sliding guidance for the extension of the second pushing body 600, and the lower guide wheel 404 provides support and sliding guidance for the extension of the first pushing body 400. On the middle keel of the U-shaped cavity of the second pushing body 600, four sets of sliding limit blocks 604 and four sets of sliding groove limiters 605 are arranged at intervals. The sliding groove limiters 605 are used to limit the extension and retraction of the first pushing body 400, and the sliding limit blocks 604 are used to limit the extension and retraction of the second pushing body 600. In use, a first servo motor 52 is installed on the front sprocket 91 or the rear sprocket 91 to drive the sprocket 91 to rotate. After the buckle 94 of the first pushing body 400 is engaged with the chain, the first extension feeding distance is completed under the drive of the chain. The second pushing body 600 completes the second feeding distance under the drive of the hydraulic cylinder 501. At this time, the lifting part 603 is activated to lift up and make it level with the height of the receiving platform in the site, thus completing the receiving of materials.

[0084] In summary, the multi-functional RGV trolley structure provided by this utility model integrates three major functional designs: precise 90-degree rotation, secondary lifting and feeding, and anti-slope trolley body. It can transfer materials in a narrow opposing boiler area, avoiding the drawbacks of existing technologies that require multiple RGVs, trolleys for each slope, and dedicated personnel for unloading.
