Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, specifically relating to a quick assembly and disassembly structure for a large radio telescope actuator. Background Technology

[0002] The actuators of the FAST radio telescope are the driving devices that deform the telescope's reflecting surface. Multiple actuators are evenly distributed below the reflecting surface, characterized by their large number, wide distribution, and complexity. As hydraulic devices, actuators are prone to failure during telescope operation, requiring timely repair. Due to site constraints, some faulty actuators need to be removed, transported back to the workshop for repair, and new actuators installed on-site to ensure the telescope's continued operation.

[0003] The actuator is connected to the pull cable at the top and to the ground anchor base at the bottom, both using pin connections. When installing the actuator, it must be secured before connecting the top and bottom ends; the same applies when removing it. Due to the large number of actuators and their location at the telescope site, the complex field environment, and the fact that some actuators are located on steep slopes, the installation and removal of the actuators present significant challenges.

[0004] Therefore, the key to telescope actuator maintenance is how to quickly and effectively install and remove actuators. Utility Model Content

Similar technologies and methods should be considered within the scope of protection of this utility model. To make the technical problem to be solved, the technical solution, and the advantages of this utility model clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0023] This utility model provides a quick-assembly and disassembly structure for an actuator of a large radio telescope, comprising: a fixing component, a connecting component, and a supporting component, wherein...

[0024] The support is a bracket body, including a first bracket rod, a second bracket rod, and a diagonal brace. The first end of the first bracket rod is connected to the first end of the second bracket rod, and the angle formed between the first bracket rod and the second bracket rod is an obtuse angle. The first end of the diagonal brace is connected to the first bracket rod at a certain distance from its second end, and the second end of the diagonal brace is connected to the second bracket rod at a certain distance from its second end.

[0025] The fastener is disposed at the second end of the second support rod;

[0026] The connector is located at the first end of the first support rod.

[0027] Furthermore, the length of the first support rod is less than or equal to the length of the second support rod.

[0028] Furthermore, the obtuse angle is 100°.

[0029] Furthermore, the specified distance is two-thirds of the length of the first or second support rod.

[0030] Furthermore, the fixing element is a square fork-shaped fixing block.

[0031] Furthermore, the connector is a chain hoist.

[0032] Furthermore, a U-shaped hook is provided at the second end of the first support rod, and the chain hoist is connected to the support member through the U-shaped hook.

[0033] Furthermore, the chain hoist is a 1-ton hand chain hoist, which is available on the market and is an existing product.

[0034] Specifically, such as Figure 1As shown, the support structure is implemented using a bracket body, which is an obtuse triangle of approximately 100 degrees. The diagonal braces connect at two-thirds of the way down the triangle, specifically at the two-thirds distance from the ends of the first and second support rods of the bracket body. This design ensures a stable connection. A U-shaped hook is welded to the upper end (second end) of the first support rod for connecting the chain hoist. The fixing mechanism uses a square fork-shaped locking block made of nylon to prevent damage to the actuator and ground anchor base. During use, this locking block is inserted between the actuator and the ground anchor base to secure the actuator and prevent lateral swaying. The chain hoist is a 1T manual chain hoist. During use, one end is hooked onto the U-shaped hook on the bracket body, and the other end is attached to the actuator to prevent it from falling forward to the ground. Therefore, the entire structure is simple, lightweight, easy to assemble, disassemble, and carry, convenient for on-site use, and suitable for assembling and disassembling actuators on various slopes.

[0035] The procedure for removing the actuator using this structure is as follows:

[0036] The support frame 1 is placed on the ground as a supporting structure. The lower end of the second support rod of the support frame extends into the ground anchor base. The fixing block 2, located at the lower end of the second support rod, is inserted between the actuator and the ground anchor base to fix the bottom of the actuator 4 and prevent the actuator from swaying left and right. Then, a sling is tied to the upper part of the actuator cylinder. One end of the chain hoist 3 is hooked onto the U-shaped hook on the support frame, and the other end is hooked onto the sling, thus connecting to the upper part of the actuator cylinder. The actuator cylinder is tied to the sling, and the hook of the chain hoist is hooked onto the sling to protect the actuator from direct contact with the chain hoist. Therefore, the sling is used to protect the actuator and prevent the chain hoist from wearing down the actuator and causing damage.

[0037] Chain hoist 3 tightens the actuator to prevent it from falling forward. The actuator extends its piston rod, de-tensioning the pull cable connected to it. At this point, remove the pin between the actuator and the pull cable to disengage the actuator from the cable. Then, retract the actuator piston rod, loosen chain hoist 3, and place the actuator on the ground. Extending and retracting the actuator piston rod are functions of the actuator itself and are independent of this disassembly / reassembly mechanism. During this process, chain hoist 3 remains stationary, merely serving to secure the actuator.

[0038] Next, remove the fixing block 2, then remove the bracket body 1, remove the connecting pin between the actuator and the ground anchor base, and remove the actuator to complete the removal of the actuator.

[0039] During installation:

[0040] Place the actuator on the ground anchor base and adjust its position to connect the actuator to the ground anchor base using the connecting pin.

[0041] The sling is tied to the upper part of the actuator cylinder, the bracket 1 is placed on the ground, and the lower end of the second bracket rod of the bracket 1 extends into the ground anchor base.

[0042] One end of the chain hoist 3 is hooked onto the U-shaped hook on the bracket body, and the other end is hooked onto the sling set on the upper part of the actuator cylinder body;

[0043] The fixing block 2 is inserted between the actuator and the ground anchor base to fix the bottom of the actuator 4.

[0044] Operate chain hoist 3 so that the actuator direction is approximately aligned with the pull cable. Operate the extended actuator piston rod and adjust the actuator position by adjusting the chain length of chain hoist 3 to facilitate connection with the pull cable. Once adjusted to the appropriate position, insert the pin to connect the actuator to the pull cable.

[0045] Loosen chain hoist 3, remove its hook connecting bracket 1 and actuator cylinder, release actuator cylinder sling, remove fixing block 2, remove bracket 1, and complete actuator installation.
