Description

Technical Field

[0001] This utility model relates to the field of coal mine protection technology, and in particular to a quick-installing goaf support frame. Background Technology

[0002] The development of goaf management technology is a crucial aspect of ensuring safe coal mine production. In coal mining, a goaf refers to the empty area left after the ore body is removed during mining. To reduce safety hazards in goafs, measures such as grouting, filling, or support are often used to reinforce them and prevent disasters such as ground subsidence and landslides.

[0003] When installing the support frame, each component needs to be transported to the work surface and assembled sequentially. After estimating the height, the height and angle of the support frame are adjusted to ensure it is firmly in contact with the mine wall. During installation, workers must continuously check the stability and adaptability of the support frame to prevent loosening. The installation process is cumbersome and time-consuming, often resulting in low work efficiency and potential safety hazards. Utility Model Content

[0004] The technical problem this invention aims to solve is that the installation steps of the goaf support frame are cumbersome and the work efficiency is low.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a quick-installing goaf support frame, including a plate body, with connecting chambers fixedly arranged on both sides of the plate body, and sliding sleeves fixedly connected to both sides of the connecting chambers. A push motor is built into both sides inside the connecting chambers, and a push plate is provided at the output end of the push motor and slidably connected to the sliding sleeve. A movable plate is fastened to the push plate by bolts, and a push rod motor is fixedly connected to the bottom of the movable plate. The push rod of the push rod motor passes through the movable plate and is fastened to the top of the support plate.

[0006] As a further improvement of this utility model, each push rod is fixedly provided with a threaded support at its top and the threaded support is provided with a threaded hole through it. The two sides of the support plate are fastened to the two threaded supports by bolts.

[0007] As a further improvement of this utility model, the top of the support plate is provided with an assembly groove, the assembly groove is fitted with a reinforcing strip, and the bottom side of the reinforcing strip is threaded with a bolt that penetrates the support plate.

[0008] As a further improvement of this utility model, two omnidirectional casters are fixedly provided at the bottom of the mobile flat plate.

[0009] As a further improvement of this utility model, a guide block is fixedly connected to the top of the push plate, and a guide groove is provided on the top of the sliding sleeve for the guide block to slide.

[0010] As a further improvement of this utility model, the plate is fixedly connected to a push handle via a connecting compartment on one side, and a controller is fixedly installed on the push handle.

[0011] The beneficial effects of this utility model are as follows: By setting a controller on the push handle, the push motor inside the connecting chamber and the push rod motor at the bottom of the moving plate can be driven and adjusted. This causes the push plate at the output end of the push motor to extend to both sides until it abuts against the edge of the mining area. Then, the push rod motor drives the push rod at the output end to move upward, so that the support plates and reinforcing strips on both sides of the top are reinforced and abutted against the cover on the top side of the mining area. This makes the operation convenient, saves assembly time, and improves work efficiency. Attached Figure Description

[0017] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0018] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides a quick-installation goaf support frame;

[0021] As attached Figure 1-4 As shown, the device includes a plate body. Connecting chambers 2 are fixedly installed on both sides of the plate body 1. Sliding sleeves 3 are fixedly connected to both sides of the connecting chambers 2. A push handle is fixedly connected to the plate body 1 via one side of the connecting chamber 2. A controller 12 is fixedly installed on the push handle. The controller 12 is electrically connected to a push rod motor 7 and a push motor. Push motors are built into both sides inside the connecting chambers 2. A push plate 4, slidably connected to the sliding sleeve 3, is provided at the output end of the push motor. A movable plate 6 is fastened to the push plate 4 by bolts. Two universal casters are fixedly installed at the bottom of the movable plate 6, providing convenient mobility for the device. A push rod motor 7 is fixedly connected to the bottom of the movable plate 6. The push rod of the push rod motor 7 passes through the movable plate 6 and is fastened to a support plate 8 at its top.

[0022] As attached Figure 3 As shown, each push rod has a threaded support 9 fixedly mounted on its top, and the threaded support 9 has a through-hole threaded hole. The support plate 8 is fastened to the two threaded supports 9 on both sides by bolts. The support plate 8 has an assembly groove 10 on its top, and a reinforcing strip 11 is engaged in the assembly groove 10. The bottom side of the reinforcing strip 11 is threaded with a bolt that passes through the support plate 8. The top of the reinforcing strip 11 has anti-slip texture. The support plate 8 is fastened to the reinforcing strip by the assembly groove 10 and bolts, which improves the stability of the support structure. The anti-slip texture of the reinforcing strip 11 is used to increase the friction between the reinforcing strip 11 and the cover on the top side of the mining area, thereby improving safety.

[0023] Working Principle: In practical implementation, the device is moved to the underground goaf area. First, the controller 11 drives the push motor in the connecting chamber 2 to push the push plate 4 in the sliding sleeve 3 to both sides. Under the guidance of the guide groove 5 and the guide block, the push plate 4 extends and displaces to both sides of the plate body 1. Finally, the movable plate 6, which is fastened to the push plate 4, abuts against the support edge side of the goaf area. Then, the controller 11 drives the push rod motor 7 at the bottom of the movable plate 6, causing the push rod at its output end to move upward, driving the support plates 8 on both sides to move upward, so that the reinforcing strip 11 is fastened and abuts against the cover on the top side of the mining area. This provides convenient and efficient support for the work area and ensures the personal safety of the construction workers.
