Description

Technical Field

[0001] The present invention relates to the field of heavy-load sliding mobile equipment, and more specifically, to a ring-rail type hydraulically driven sliding shoe device. Background Art

[0002] Conventional sliding mobile equipment often adopts oil cylinders and moves intermittently. During the sliding movement, the driving oil cylinder can only be pushed again after it is locked. There is a reverse impact when changing from a static state to a sliding state. This impact brings negative damage to the sliding track. At the same time, when the oil cylinder drives the heavy sliding mobile equipment, due to the inertial force of the intermittent movement of the sliding mobile equipment, it also causes instantaneous oil pressure shock to the oil cylinder and its oil pump station system. Frequent periodic oil pressure shocks are not good for various hydraulic components and sealing effects. At the same time, the oil cylinder drive occupies part of the track, which is not conducive to the overall layout of the heavy-loaded sliding mobile equipment and is only suitable for the case of straight tracks. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a ring-rail type hydraulically driven sliding shoe device, which has the advantage of more precise operation.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 5As shown, the present invention provides a ring rail type hydraulically driven slipper device, comprising: a slipper body 2, a bearing shaft structure 3, a guide structure 4, a cylinder drive unit 5 and a hydraulic pump station 6, wherein the slipper body 2 is arranged in the ring rail 1; the guide structure 4 is provided with two groups, which are respectively arranged at the two ends of the slipper body 2, and the guide structure 4 is in contact with the ring rail 1; the bearing shaft structure 3 is sleeved on the upper part of the slipper body 2 in the form of a shaft, and the cylinder drive unit 5 is arranged on both sides of the slipper body 2, respectively in contact with the inner walls of both sides of the ring rail 1, and the cylinder drive unit 5 is powered by the hydraulic pump station 6.

[0019] The shoe body 2 slides in the annular slide rail 1, and the laying foundation of the annular slide rail 1 needs to meet the load-bearing requirements; the bearing shaft structure 3 is mounted on the shoe body 2 in the form of a shaft. In principle, the bearing shaft structure 3 only bears the downward pressure from the upper structure. In order to facilitate disassembly and assembly, the bearing shaft structure 3 can also bear its own gravity when it is designed. The bearing shaft structure 3 facilitates the micro-rotation movement of the shoe body 2 during the sliding process, and also facilitates the shoe body 2 to adapt to various installation angles; the guide structure 4 is installed at the front and rear ends of the shoe body 2 to provide guidance for the sliding of the shoe body 2 and bear the impact of operation. The guide structure 4 is a replaceable part; the cylinder drive unit 5 is installed on both sides of the shoe body 2, a total of 2 sets, alternately clamping and retracting the cylinder to drive the shoe body 2 to slide forward. The force of extending and retracting the cylinder is different, and the extension direction is usually the same as the sliding direction of the shoe body 2; the hydraulic pump station 6 provides drive and control for the cylinder drive unit 5. When multiple sets of shoes need to be configured, the coordinated movement between the shoes can be controlled by the same hydraulic pump station 6. The rotatable function of the sliding shoe body 2 can make the design of the sliding shoe body 2 unified and can meet the needs of various arc transition tracks.

[0020] The annular slide rail 1 is equally divided into arc structures according to size requirements, and several groups of arc structures are spliced ​​together into a ring to form the annular slide rail 1.

[0021] Among them, a friction reduction plate is arranged in the annular slide rail 1 , the slide shoe body 2 is made of high-strength steel, the bottom of the slide shoe body 2 is wrapped with a stainless steel plate, and a balance beam is arranged on the upper part of the slide shoe body 2 .

[0022] The stainless steel plate at the bottom of the sliding shoe body 2 is used in conjunction with the friction reducing plate to reduce the friction of sliding during operation. The bearing capacity of the sliding shoe body 2 is limited, and the bearing requirements of the upper heavy-load equipment are met by configuring a balance beam.

[0023] The guide structure 4 is installed on both sides of the sliding shoe body 2 by bolts, and a wear-resistant strip or a guide wheel is arranged on the side where the guide structure 4 is connected to the annular slide rail 1.

[0024] Wear-resistant strips or guide wheels are set to reduce friction during operation.

[0025] Among them, a π-shaped bracket is arranged on the annular slide rail 1, and the cylinder driving units 5 on both sides of the slide shoe body 2 alternately clamp the π-shaped bracket of the annular slide rail 1 and alternately extend and retract to achieve driving.

[0026] Among them, the cylinder drive unit 5 includes a clamping cylinder 51, a pushing cylinder 52, a front-mounted hinge shaft 53, and a rear-mounted hinge shaft 54. The front-mounted hinge shaft 53 includes a hinge seat and a front hinge shaft, wherein the hinge seat is fixedly connected to the sliding shoe body 2, the front hinge shaft is installed in the hinge seat, and is connected to the pushing cylinder 52; the output end of the pushing cylinder 52 is connected to the clamping cylinder 51 through the rear-mounted hinge shaft 54.

[0027] The clamping cylinder 51 can be clamped on the π-shaped bracket of the annular slide rail 1 and serve as the force fulcrum of the pushing cylinder 52. Only after the clamping cylinder 51 is clamped, the pushing cylinder 52 can be controlled to extend; similarly, only after the clamping cylinder 51 is completely released, the pushing cylinder 52 can be controlled to retract. The front-mounted hinge shaft 53 includes the hinge seat installation and the hinge shaft assembly, and the rear-mounted hinge shaft 54 ​​only includes the hinge shaft assembly. The front and rear of the pushing cylinder 52 are both single-ear plate types.

[0028] When pushing the slipper to slide, first, the clamping cylinder 51 on one side clamps the π-shaped bracket of the annular slide rail 1, and the corresponding pushing cylinder 52 extends to push the slipper body 2 forward; at the same time, the clamping cylinder 51 on the other side is in a relaxed state, and the corresponding pushing cylinder 52 contracts, driving the clamping cylinder 51 forward.

[0029] After the clamping cylinder 51 is in place, it clamps the π-shaped bracket of the annular slide rail 1, and the corresponding pushing cylinder 52 extends to push the slide shoe body 2 forward; at the same time, the clamping cylinder 51 in the original clamping state is released, and the corresponding pushing cylinder 52 contracts, driving the clamping cylinder 51 forward.

[0030] By alternating and reciprocating as above, the sliding shoe can be continuously pushed forward. By continuously optimizing the hydraulic control, the intermittent sliding can become smoother.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
