Description

Technical Field

[0001] This utility model relates to the field of anchoring technology, specifically a maintenance-free rotating shaft anchoring device. Background Technology

[0002] Large mechanical equipment such as stackers, reclaimers, and ship loaders are commonly used in ports for the storage and handling of bulk materials. These large machines generally consist of traveling, slewing, and pitching mechanisms. In windy weather, the braking force of the traveling and slewing brakes cannot overcome the wind force, causing these large machines to move and rotate on their own under the influence of the wind, posing a significant safety hazard. Therefore, anchoring devices are installed on the traveling and slewing parts. In windy weather, the anchoring devices are released to firmly secure these large machines.

[0003] In the prior art, the authorized announcement number CN223267677U discloses an automatic execution device for windproof anchoring of a material handling machine, which includes a large machine anchoring system and an anchor seat marking system. The anchor seat marking system includes a sensor bracket, which is installed on the anchor seat. After the large machine anchoring system detects the sensor bracket, it positions the anchor seat.

[0004] The design of inserting a pin into the anchoring seat enables effective anchoring of the equipment. While this anchoring method is simple and reliable, the completely enclosed structure of the anchoring groove makes it particularly prone to accumulating various material debris during actual use. This debris gradually fills the internal space of the groove, causing severe blockage. Once blockage occurs, the narrow and enclosed space inside the groove makes cleaning extremely difficult, requiring significant time and manpower. Ultimately, this prevents the pin from properly descending into place, severely impacting the anchoring effect and operational efficiency of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a maintenance-free rotating shaft anchoring device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a maintenance-free rotating shaft anchoring device, including a bracket and an anchoring base installed on the ground, an electric push rod fixedly installed inside the bracket, a positioning plate fixedly installed on the side wall of the bracket, an anchoring block rotatably installed on the positioning plate, and a pull rod connecting the anchoring block and the output end of the electric push rod.

[0007] Preferably, a first pin is rotatably mounted on one end of the pull rod, and a second pin is rotatably mounted on the other end of the pull rod. One end of the pull rod is rotatably mounted to the output end of the electric push rod via the first pin, and the other end of the pull rod is rotatably mounted to the anchor block via the second pin.

[0008] Preferably, a third pin is fixedly installed on the positioning plate, and the anchor block is rotatably installed on the positioning plate via the third pin.

[0009] Preferably, a limit switch is fixedly installed on the side wall of the bracket, and the detection end of the limit switch is located on the rotation path of the anchor block.

[0010] Preferably, two first steel plates are fixedly installed on the anchoring base, and a second steel plate is fixedly installed on the outer side of each of the two first steel plates. Anchor bolts are connected to the anchoring base, and the anchoring base is fixedly installed on the ground by the anchor bolts.

[0011] Preferably, a lifting lug is fixedly installed on the anchor block, and the other end of the tie rod is rotatably connected to the lifting lug via a second pin. A steel pipe is fixedly installed on one end of the anchor block, and the steel pipe is rotatably installed on a third pin on the positioning plate.

[0012] Preferably, the bracket is a box girder structure assembled by welding steel plates, with two push rod positioning steel plates welded inside, and the tail of the electric push rod is fixedly installed on the positioning steel plate inside the bracket by bolts.

[0013] Preferably, the bracket has a movable hole on its side wall, and the pull rod passes through the bracket through the movable hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this application, the electric push rod extends, and the pull rod drives the anchor block to rotate downwards. When the electric push rod is fully extended, both anchor blocks on the left and right sides are in a horizontal position, with the ends of the anchor blocks at the openings of the anchor base. At this time, the anchor blocks are fixed to the anchor base and cannot move back and forth. When anchoring is no longer required, the electric push rod retracts, and the pull rod drives the anchor blocks to rotate upwards. After the limit switch is triggered, the limit switch issues a stop command, the electric push rod stops running, and both anchor blocks on the left and right sides are in a vertically upward state, thus releasing the anchoring.

[0016] 2. The anchoring device in this application is driven by an electric push rod, which is simple and easy to operate, effectively saving labor costs. The movement of the anchoring plate has been changed from vertical movement to rotation, which solves the material blockage problem of the original structure, eliminating the need for regular cleaning and maintenance. The structure of the anchoring groove has been improved from a four-sided closed form to an open structure, reducing the possibility of material blockage, and even if blockage occurs, cleaning is more convenient.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a maintenance-free rotating shaft anchoring device, including a bracket 6 and an anchoring base 10 installed on the ground. An electric push rod 1 is fixedly installed inside the bracket 6, and a positioning plate 5 is fixedly installed on the side wall of the bracket 6. An anchoring block 4 is rotatably installed on the positioning plate 5. A pull rod 2 is connected between the anchoring block 4 and the output end of the electric push rod 1. A first pin 7 is rotatably installed at one end of the pull rod 2, and a second pin 8 is rotatably installed at the other end of the pull rod 2. One end of the pull rod 2 is rotatably installed at the output end of the electric push rod 1 through the first pin 7, and the other end of the pull rod 2 is rotatably installed on the anchoring block 4 through the second pin 8. A limit switch 3 is fixedly installed on the side wall of the bracket 6, and the detection end of the limit switch 3 is located on the rotation path of the anchoring block 4.

[0026] Specifically, when the electric push rod 1 begins to extend, its piston rod gradually extends outward, driving the connected pull rod 2 to move synchronously. Driven by the electric push rod 1, the pull rod 2 transmits force to the connection point of the anchor block 4, causing the anchor block 4 to rotate downward around its fixed fulcrum. As the electric push rod 1 continues to extend, the anchor blocks 4 on both sides gradually rotate from their initial vertical position to a horizontal position. When the electric push rod 1 reaches its fully extended state, both anchor blocks 4 are precisely rotated to a horizontal position, at which point the ends of the anchor blocks 4 are precisely aligned with and embedded in the preset opening grooves on the anchor base 10. In this state, the anchor blocks 4 and the anchor base 10 form a firm mechanical fit, completely restricting any displacement of the anchor blocks 4 in the front-to-back direction, achieving reliable anchoring and locking. When it is necessary to release the anchor, the electric push rod 1 begins to retract, its piston rod retracts inward, driving the anchor blocks 4 to rotate upward through the pull rod 2. During the rotation, when the anchor blocks 4 reach the preset vertical position, they will touch the limit switch 3 installed in the appropriate position. Once the limit switch 3 is triggered, it immediately sends a stop signal to the control system, and the electric push rod 1 stops moving. At this time, both left and right anchor blocks 4 return to their initial vertically upward position, completely disengaging from the anchor base 10, and the system successfully releases the anchoring state.

[0027] Example 2: Figure 3 , Figure 4 and Figure 5 As shown, two first steel plates 11 are fixedly installed on the anchor base 10, and second steel plates 12 are fixedly installed on the outer side of each of the two first steel plates 11. Anchor bolts 13 are connected to the anchor base 10, and the anchor base 10 is fixedly installed on the ground by the anchor bolts 13.

[0028] Specifically, the first steel plate 11 and the second steel plate 12 are firmly welded to the upper surface of the anchoring base 10. These two steel plates not only form a stable connection with the anchoring base 10, but they are also tightly integrated into a single structure through welding. The two first steel plates 11 are precisely calculated and positioned to form an opening of a specific size, perfectly accommodating the entry of the anchoring block 4.

[0029] Example 3: Figure 3 , Figure 4 and Figure 6 As shown, a third pin 9 is fixedly installed on the positioning plate 5, and the anchor block 4 is rotatably installed on the positioning plate 5 through the third pin 9. A lifting lug 401 is fixedly installed on the anchor block 4, and the other end of the tie rod 2 is rotatably connected to the lifting lug 401 through the second pin 8. A steel pipe 402 is fixedly installed on one end of the anchor block 4, and the steel pipe 402 is rotatably installed on the third pin 9 on the positioning plate 5.

[0030] Specifically, the pull rod 2 connected to the lifting lug 401 can drive the movement of the anchor block 4 by applying a pulling or pushing force, so that the anchor block 4 can rotate around the third pin 9. When the pull rod 2 is subjected to an upward pulling force, it will drive the anchor block 4 to rotate upward, thereby realizing the unlocking function; conversely, when the pull rod 2 is subjected to a downward pushing force, it will push the anchor block 4 to rotate downward, completing the locking action.

[0031] Working principle: When anchoring is required, the electric push rod 1 extends, and the pull rod 2 pushes the anchor block 4 to rotate downward. After the electric push rod 1 is fully extended, both the left and right anchor blocks 4 are in a horizontal state, and the ends of the anchor blocks 4 are located at the openings on the anchor base 10. At this time, the anchor blocks 4 are anchored to the anchor base 10 and cannot move back and forth. When anchoring is not required, the electric push rod 1 retracts, and the pull rod 2 drives the anchor blocks 4 to rotate upward. After triggering the limit switch 3, the limit switch 3 sends a stop signal, the electric push rod 1 stops moving, and both the left and right anchor blocks 4 are in a vertically upward state, thus releasing the anchoring state.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
