Description

Technical Field

[0001] This utility model relates to the field of tippler technology, and in particular to a four-link hydraulic tippler device for both open and closed tipplers. Background Technology

[0002] In conventional tippler operations, the typical tipping angle range of the tippler is usually insufficient to completely remove residual material from the wagon compartment. Due to the combined effects of material characteristics (such as moisture and viscosity) and friction on the wagon compartment surface, manual cleaning of residues is still required after tipping, significantly reducing operational efficiency.

[0003] To improve cleanliness, the industry has attempted to increase the tipping angle to an unconventional range. However, when a tipper performs a large-angle tipping of a container or open wagon exceeding 180°, a dedicated wagon-holding device needs to be added to the non-tipping side to stabilize the wagon. For example, an invention disclosed in publication number CN110356874B provides a wagon-holding device for both containers and open wagons.

[0004] In existing tippler docking devices, a top-supported docking plate structure is commonly used. The docking plate movement is driven by a hydraulic system linked to hinged strut devices at both ends. Specifically, each end of the docking plate structure has a strut device, with one end hinged to the docking plate structure and the other end hinged to a strut support. Four hydraulic cylinders are connected to the rear of the docking plate structure, driving the docking plate structure forward and backward via a hydraulic system.

[0005] As described above, existing support structures rely on the synchronous control of multiple hydraulic cylinders to achieve the displacement of the support plate. Due to limitations in the dynamic response characteristics of the hydraulic system and the precision of the mechanical articulation, motion deviations are prone to occur during the coordinated action of multiple cylinders, causing the support plate to tilt during extension and retraction. When the extended support plate tilts, the contact pressure distribution between the support surface and the car body becomes unbalanced, which can easily lead to abnormal deformation of the car body structure and affect operational safety. Utility Model Content

[0006] In view of this, this utility model proposes a four-link hydraulic car-supporting device for a dual-purpose open and closed wagon tipper. It reduces motion deviation by designing a parallelogram hinge mechanism and ensures that the car-supporting plate remains vertical during extension and retraction. This makes the contact pressure between the car-supporting surface and the wagon body evenly distributed, less likely to cause wagon body deformation, and is beneficial to operational safety. It solves the problem that the car-supporting plate of the existing car-supporting device is prone to tilting and causing local deformation of the wagon body.

[0040] The four-link hydraulic vehicle-supporting device for a dual-purpose open / container tippler of this utility model has the following advantages over the prior art:

At the same time, by utilizing the geometric constraint characteristics of the parallelogram, it can be ensured that the car-mounted plate is always in a vertical state during the extension and retraction process. When the car-mounted plate is in contact with the car body, the contact pressure distribution between the car-mounted plate and the car body is uniform, which is not easy to cause deformation of the car body and is conducive to work safety.

[0042] (2) By setting up bosses and clearance holes, bolts can be installed easily, which in turn makes it easier to install and fix the upper base on the front side of the longitudinal beam.

[0043] (3) By hinged at the lower end of the rear connecting rod and the front end of the hydraulic cylinder output end on the lower hinge point on the rear side, the hydraulic cylinder can more easily drive the parallelogram hinge mechanism to deform, reduce the driving resistance, and is beneficial to the protection of the hydraulic cylinder.

[0044] (4) By setting an opening, the rotating shaft on the side of the hydraulic cylinder enters the inner side of the shaft hole through the opening, which facilitates the connection and installation of the hydraulic cylinder and the hinge support. At the same time, by setting a cover plate, and with one end of the rotating shaft rotatably set in the positioning hole, it is easy to limit the rotating shaft after installation, so that the rotating shaft is not easy to accidentally come out of the shaft hole, and ensure the fit between the rotating shaft and the shaft hole.

[0045] (5) By setting the rear end of the backrest to be detachably connected to the front end of the lower base at the corresponding position, it is easy to realize the modular design of the backrest, and thus easy to replace the backrest with a suitable size and shape as needed.

[0046] (6) By setting up a car-side plate including a frame and a rubber plate, it is easy to protect the car body with the rubber plate, and the car body is less likely to deform when it is close to the car. Attached Figure Description

[0053] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0054] like Figure 1-4 As shown, the present invention discloses a four-link hydraulic vehicle-supporting device for a dual-purpose open and closed wagon tipper, comprising a longitudinal beam 1, an upper base 2, a connecting rod 3, a lower base 4, a hydraulic cylinder 5, and a vehicle-supporting plate 6.

[0055] In this design, at least one pair of upper bases 2 are fixedly installed on the front side (vehicle-facing side) of the longitudinal beam 1 along the left-right direction. Each upper base 2 has two connecting rods 3 and a lower base 4 below it. The connecting rods 3 are hinged between the upper bases 2 and the lower bases 4 to form a parallelogram hinge mechanism. A vehicle-facing plate 6 is installed at each pair of upper bases 2, and the rear end of the vehicle-facing plate 6 is detachably connected to the front end of the corresponding lower base 4. A hydraulic cylinder 5 is hinged to the rear end of each lower base 4, and the top of the hydraulic cylinder 5 is hinged to the bottom of the longitudinal beam 1. This parallelogram hinge mechanism achieves a four-bar linkage design, requiring only two hydraulic cylinders 5 on the rear side of each vehicle-facing plate 6. Compared to the existing four-cylinder drive structure, the number of hydraulic cylinders 5 used in this vehicle-facing device is reduced, effectively minimizing movement deviation. Simultaneously, the geometric constraint characteristics of the parallelogram ensure that the vehicle-facing plate 6 remains vertical during extension and retraction. When approaching the vehicle, the contact pressure between the vehicle-facing surface of the vehicle-facing plate 6 and the surface of the carriage is evenly distributed, reducing the likelihood of carriage deformation and improving operational safety.

[0056] Figure 1 In the middle, there are two car-side panels 6. In actual applications, three or more can also be set to meet the car-side needs of longer carriages.

[0057] A boss 11 is provided on the front side of the longitudinal beam 1 and at the position corresponding to the upper base 2. A clearance hole 1101 is provided on the rear side of the boss 11, and the clearance hole 1101 passes through the boss 11 from left to right. A bolt mounting hole 1102 is provided at the front end of the boss 11, which communicates with the clearance hole 1101 from front to back. The upper base 2 is fixed to the front end of the boss 11 by bolts. Figure 2 In the upper base 2, the boss 11 is vertically oriented in a rectangular shape, and the clearance hole 1101 on its rear side is used to accommodate a nut. The upper base 2 is also provided with holes for mounting bolts. During installation, the bolt is passed through the holes on the upper base 2 and the bolt mounting holes 1102, and then the nut is placed inside the clearance hole 1101 and screwed onto the bolt. After tightening, the upper base 2 is installed and fixed.

[0058] Because of the clearance hole 1101, it is convenient for the assembly worker to perform assembly operations on the back side of the boss 11, thereby facilitating the installation operation of the upper base 2.

[0059] The bottom of the upper base 2 has two upper hinge points 201, which are spaced apart and horizontally aligned; each upper hinge point 201 is hinged to a connecting rod 3. (Combined) Figure 4 The two connecting rods 3 are parallel to each other and spaced apart, and are of equal length. The top of the lower base 4 is provided with two lower hinge points 401, which are spaced apart and horizontally aligned. The lower end of the front connecting rod 3 is hinged to the front lower hinge point 401. The lower end of the rear connecting rod 3 and the front end of the output end of the hydraulic cylinder 5 are both hinged to the rear lower hinge point 401.

[0060] Figure 3 In the design, both the upper hinge point 201 and the lower hinge point 401 have a U-shaped groove structure. During installation, a pin is used to achieve the hinged installation of the connecting rod 3. Specifically, the upper end of the connecting rod 3 is located inside the upper U-shaped groove, and then a pin is used to horizontally penetrate the groove wall of the U-shaped groove and the upper end of the connecting rod 3 to achieve the hinge. The two connecting rods 3 are installed independently. Similarly, the lower end of the front connecting rod 3 is hinged to the front lower hinge point 401 by another pin.

[0061] The lower end of the rear connecting rod 3 is provided with a clearance groove 301. The front end of the output end of the hydraulic cylinder 5 is located inside the clearance groove 301. A pin passes through the lower rear hinge point 401, and this pin passes through the wall of the lower U-shaped groove, the lower end of the rear connecting rod 3, and the output end of the hydraulic cylinder 5, thus achieving the hinge connection of the three. When the output end of the hydraulic cylinder 5 extends, the lower base 4 moves forward, realizing the vehicle-mounted plate 6's vehicle-mounting action. Conversely, when the output end retracts, the lower base 4 moves backward. During the process, the two connecting rods 3 swing synchronously. Since the lower end of the rear connecting rod 3 and the front end of the output end of the hydraulic cylinder 5 are both hinged to the lower rear hinge point 401, the hydraulic cylinder 5 can more easily drive the parallelogram hinge mechanism to deform, reducing driving resistance and protecting the hydraulic cylinder 5.

[0062] A hinge support 7 is fixed at the bottom of the longitudinal beam 1, and the hydraulic cylinder 5 is hinged to the inner side of the hinge support 7. Specifically, a shaft hole 701 is provided through the side of the hinge support 7 in the left-right direction, and an opening 7011 is provided on the side of the shaft hole 701; a rotating shaft 51 is fixedly provided on the side of the hydraulic cylinder 5, and the rotating shaft 51 enters the inner side of the shaft hole 701 through the opening 7011, and the rotating shaft 51 is rotatably connected to the shaft hole 701. This structure facilitates the connection and installation of the hydraulic cylinder 5 and the hinge support 7.

[0063] To prevent accidental detachment of the shaft, a cover plate 8 is bolted to the side of the hinge support 7. A positioning hole 801 is provided through the cover plate 8 in the left-right direction, and one end of the rotating shaft 51 is rotatably positioned in the positioning hole 801. This structure limits the installation of the rotating shaft 51, making it difficult for the rotating shaft 51 to accidentally detach from the shaft hole 701, and ensuring the proper fit between the rotating shaft 51 and the shaft hole 701.

[0064] The backrest panel 6 includes a frame 61 and a long strip of rubber sheet 62. The rear end of the frame 61 is fixedly connected to the front end of the lower base 4 by bolts; the rubber sheet 62 is fixed to the front end of the frame 61 by bolts. This structure enables a modular design for the backrest panel 6, facilitating the replacement of backrest panels 6 with appropriate sizes and shapes as needed. Simultaneously, the rubber sheet 62 increases the contact area and fit between the carriage and the backrest device, reducing stress on the carriage and protecting it.

[0065] The method of using the four-link hydraulic wheelbarrow resting device of the open-top / container dual-purpose tippler of this utility model is as follows:

[0066] When the vehicle is approaching the car, hydraulic cylinder 5 drives the lower base 4 to move horizontally towards the car body. The lower base 4 drives the approach plate 6 to move horizontally simultaneously, eventually bringing the approach plate 6 against the side of the car body. After approaching the car, hydraulic cylinder 5 drives the lower base 4 to return along the same path, causing the approach plate 6 to move away from the side of the car body.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
