Description

Technical Field

[0001] The utility model relates to the field of gates at loading stations, and particularly to a gate assembly for a loading station. Background Art

[0002] A loading station is a large-scale automated mechanical device for quickly and quantitatively loading bulk goods, which has the advantages of accurate metering, balanced loading, high speed, and high efficiency, and is commonly used for bulk materials such as coal and ore. The loading method of the loading station is through-type, and the continuous feeding process upstream is converted into an appropriate working cycle through the in-station equipment. When the materials accumulate to a certain quantity, the loading system starts. The materials are discharged through the buffer bin batching gate into the quantitative bin for accurate batching. After batching, the materials are discharged from the quantitative bin discharge gate into the chute part, and the materials are evenly loaded into the train car through the chute arc gate, realizing fixed-point and quantitative accurate loading.

[0003] The gate is one of the main components of the loading system. The gate consists of a flat gate plate and a hydraulic cylinder. The flat gate plate reciprocates within the gate housing to achieve accurate discharging into the carriage. The gate of the loading system generally controls the opening and closing size of the gate through a travel switch. Full-open travel switches, intermediate position travel switches, and full-closed position travel switches can be set to achieve precise loading control. At the same time, the opening and closing size of the gate can also be controlled according to the loading needs and time to meet different loading requirements.

[0004] Due to the impact of the materials on the flat gate plate, the piston rod of the hydraulic cylinder connected to it is subjected to a downward force. At the same time, due to the wear of the slideway and the gate plate within the gate housing, the piston rod is subjected to a left-right force, resulting in damage to the seal at the front end of the cylinder and premature failure of the cylinder. Summary of the Utility Model

[0032] In order to make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0033] In the prior art, the hydraulic cylinder is fixedly arranged on the brake housing, restricting all its degrees of freedom. However, due to the special and complex working conditions of the brake plate and the existence of wear, the piston rod swings, further causing the hydraulic cylinder to leak and fail. To solve this technical problem, the inventor analyzed the force and movement conditions of the hydraulic cylinder and creatively installed the hydraulic cylinder movably on the brake housing, enabling the hydraulic cylinder to follow the movement of the brake plate, greatly reducing the acting force between the various components of the hydraulic cylinder and extending the service life of the hydraulic cylinder. Specific embodiment one

[0035] Such as Figure 1 and Figure 2As shown in the figure, this specific embodiment provides a gate assembly for a loading station, which includes a gate body and a hydraulic cylinder. The gate body includes a gate plate and a gate housing. The gate plate can reciprocate along the slideway inside the gate housing. The hydraulic cylinder is connected to the mounting seat 2 through a universal coupling assembly. The hydraulic cylinder can swing up and down and left and right. The piston rod 1 of the hydraulic cylinder is connected to the gate plate, and the mounting seat 2 is connected to the gate housing.

[0036] In this specific embodiment, the hydraulic cylinder is connected to the mounting seat 2 through a universal coupling, so that the hydraulic cylinder has at least the freedom to swing in the vertical plane and the horizontal plane. When the piston rod 1 is subjected to the force of the gate plate, it can drive the whole hydraulic cylinder to follow, so that the front seal no longer bears a large dynamic load. Furthermore, the service life of the hydraulic cylinder is prolonged and premature failure is avoided.

[0037] As Figure 3 and Figure 4 shown in the figure, in this specific embodiment, the universal coupling assembly can adopt the following structure: the universal coupling assembly includes a vertically arranged swing frame 3. Symmetrically arranged on both sides of the swing frame 3 are support shafts 3.1. The support shafts 3.1 are rotatably arranged on the corresponding mounting seats 2 through bearings. Opposite to the outer circumference of the cylinder body 4 of the hydraulic cylinder are arranged rotating shafts 5. The cylinder body 4 horizontally penetrates the swing frame. The rotating shafts 5 are perpendicular to the support shafts 3.1. The rotating shafts 5 are rotatably arranged on the swing frame 3 through the corresponding bearings. In this specific embodiment, by using the cooperation of the swing frame 3 and the rotating shafts 5, the follow-up of the hydraulic cylinder in the up and down and left and right directions is satisfied, and the vertical and left and right forces given by the gate plate can be borne. It has high reliability, simple structure, and is convenient for manufacturing, disassembly and assembly. The two rotating shafts 5 are vertically arranged, and the support shafts 3.1 are horizontally arranged. By arranging the support shafts 3.1 horizontally, it is more convenient for disassembly and assembly on the left and right sides of the mounting seat 2 than on the upper and lower sides.

[0038] Since the hydraulic cylinder is suspended and installed on one side of the gate housing, in order to enhance the support strength of the mounting seat 2 and the hydraulic cylinder, in this specific embodiment, a support seat is provided on the gate housing. Triangular reinforcing plates are provided between both sides of the support seat and the gate housing. The mounting seat 2 is detachably arranged on the support seat through bolts. Along the extending direction of the hydraulic cylinder, the mounting seat 2 is arranged at the rear of the support seat. A tubing through hole is provided on the side surface of the support seat opposite to the front oil hole 6 of the hydraulic cylinder, which is convenient for the tubing of the hydraulic cylinder to enter and exit.

[0039] In the prior art, the diameter of the mounting hole provided on the gate housing is slightly larger than the diameter of the piston rod 1. However, in this specific embodiment, since the piston rod 1 has the freedom to swing, in order to avoid interference and prevent the overflow of materials and dust, a mounting hole is provided on the gate housing. The diameter of the mounting hole is D1, and the diameter of the piston rod 1 of the hydraulic cylinder is D2. 2.2*D2 ≤ D1 ≤ 3*D2. In this specific embodiment, the diameter of the piston rod 1 is 56 mm, and the diameter of the mounting hole is 160 mm.

[0040] This specific embodiment further includes a bellows dust cover. One end of the bellows dust cover is connected to the cylinder block 4 of the hydraulic cylinder, and the other end of the bellows dust cover is connected to the brake housing. By providing the bellows dust cover, dust leakage can be further prevented from polluting the environment. Specific Embodiment 2

[0042] As Figures 5 to 7 shown, this specific embodiment has basically the same structure as Specific Embodiment 1, except that: in order to cope with more complex working conditions and meet the use requirements, in this specific embodiment, the universal coupling assembly includes a ball head 10 and a ball housing 7. The ball head 10 is rotatably arranged in the ball housing 7. The ball head 10 is provided with a mounting hole, and the cylinder block 4 of the hydraulic cylinder is connected to the ball head 10 through the mounting hole. The ball housing 7 is arranged between two mounting seats 2. Specifically, two limiting shafts 8 are symmetrically arranged on the outer circumferential surface of the ball housing 7, and the limiting shafts 8 are arranged in the corresponding mounting seats 2. To prevent the ball housing 7 from rotating, a limiting bolt 9 is arranged on the mounting seat 2. The limiting bolt 9 is perpendicular to the limiting shaft 8 and extends into the support shaft 3.1 to prevent the ball housing 7 from rotating and moving left and right, reducing the force exerted by the mounting seat 2 on the movement of the ball housing 7 and affecting the connection life. When the brake plate transmits a force to the piston rod 1, it drives the cylinder block 4 to swing, and then the ball head 10 rotates a certain angle in the ball housing 7, avoiding the interaction between the components of the oil cylinder and affecting the performance of the oil cylinder.

[0043] As Figure 6 shown, in this specific embodiment, the limiting shafts 8 are horizontally arranged, which enables the mounting seats 2 to be installed on the left and right sides. Compared with the upper and lower sides, it is more convenient for disassembly and assembly.

[0044] It can be seen from the above specific embodiments that the present utility model has the following beneficial effects:

[0045] 1. Connect the hydraulic cylinder to the mounting seat 2 through a universal coupling, so that the hydraulic cylinder has at least the freedom to swing in the vertical plane and the horizontal plane. When the piston rod 1 is subjected to the force of the brake plate, it can drive the entire hydraulic cylinder to follow, so that the front seal no longer bears a large dynamic load. Furthermore, the service life of the hydraulic cylinder is extended, and premature failure is avoided.

[0046] 2. By using the form of ball hinge to realize the swing of the hydraulic cylinder, the hydraulic cylinder can follow the brake plate in multiple directions and can adapt to more complex force conditions.

[0047] 3. By using the cooperation of the swing frame 3 and the rotating shaft 5, the follow-up of the hydraulic cylinder in the up-down and left-right directions is satisfied, and the vertical and left-right forces given by the brake plate can be borne. It has high reliability, simple structure, and is convenient for manufacturing, disassembly and assembly.

[0048] 4. By setting the support base and the reinforcing plate, the support strength of the mounting base 2 can be enhanced, and disassembly and assembly are facilitated; by defining 2.2*D2 ≤ D1 ≤ 3*D2, on the one hand, the swinging space of the piston rod 1 can be ensured to avoid interference with the brake housing, and on the other hand, excessive dust spillage and environmental pollution caused by too large mounting holes can be avoided;

[0049] 5. By setting the bellows dust cover, dust leakage and environmental pollution can be further prevented.

[0050] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
