Description

Technical Field

[0001] This utility model relates to the field of support equipment technology, and in particular to a quick-installation steel arch support device for coal mine roadways. Background Technology

[0002] Steel arch support equipment is an arch-shaped structure made of steel profiles through welding or cold bending processes. It is mainly used for the support of underground engineering such as tunnels and roadways. The steel arch frame provides bending stiffness through its high cross-section moment of inertia, converting the surrounding rock pressure into axial force and transmitting it to the arch foot, thereby achieving stable support.

[0003] Steel arch support can be either integral or segmented. Integral steel arch support usually refers to the steel arch frame being prefabricated in the factory and then transported to the construction site for installation. Segmented steel arch support involves dividing the steel arch frame into multiple segments, transporting them to the site separately, and then assembling them into a whole.

[0004] Segmented steel arch support typically uses welding to connect the segmented steel arch frames into a whole. However, the environment of coal mine roadways is relatively complex and contains flammable and explosive gases such as methane. In such a complex construction environment, welding operations are difficult and welding quality is hard to guarantee, thus affecting the reliability and stability of the connection.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 Reference Figures 1-3 This is the first embodiment of the present utility model, which provides a quick-installation coal mine roadway steel arch support device, including a vertical support 1, two vertical supports 1 connected to an arc support 2, and a fixing component 3 connecting the vertical support 1 and the arc support 2. The fixing component 3 includes a first receiving groove 301 and a second receiving groove 302. The first receiving groove 301 is formed on the vertical support 1, and the second receiving groove 302 is formed on the arc-shaped support 2. A baffle 303 is slidably connected in the first receiving groove 301 and the second receiving groove 302. A rod 304 is fixedly connected to the baffle 303. The rod 304 passes through the first receiving groove 301 and the vertical support 1. A handle 305 is fixedly connected to the end of the rod 304 away from the baffle 303.

[0023] The baffle 303 is cross-shaped, and the first receiving groove 301 is fixedly installed with a limit bracket 306. The four limit brackets 306 are V-shaped.

[0024] The insertion rod 304 is fitted with a spring 307. One end of the spring 307 is fixedly connected to the first receiving groove 301, and the other end of the spring 307 is fixedly connected to the baffle 303.

[0025] The vertical support 1 is provided with an alignment groove 4, and the arc support 2 is provided with an alignment protrusion 5. The alignment protrusion 5 is fitted into the alignment groove 4. The first receiving groove 301 is provided on the alignment groove 4, and the second receiving groove 302 is provided on the alignment protrusion 5.

[0026] Example 2 Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the alignment groove 4 and the alignment protrusion 5 are connected by an auxiliary component 6. The auxiliary component 6 includes a socket 601, which passes through the alignment groove 4 and the alignment protrusion 5. A screw 602 is provided inside the socket 601. Locking nuts 603 are threaded to both ends of the screw 602. Pins 604 are rotatably connected to both ends of the screw 602. A handle 605 is rotatably connected to the pins 604. The handle 605 is eccentrically connected to the pins 604.

[0027] The locking nut 603 is threadedly connected to the fine-tuning nut 606, and the handle 605 consists of an eccentric cylinder and an extension handle.

[0028] Before the vertical support 1 and the arc support 2 are spliced, the cross edge of the baffle 303 is located in the V-groove of the limit frame 306, at which time the spring 307 is in a compressed state.

[0029] In use, the vertical support 1 and the arc support 2 are quickly aligned and spliced ​​together by the alignment protrusion 5 and the alignment groove 4. Then, the handle 305 is pulled outward, and the handle 305 moves the insertion rod 304 and the baffle 303. The baffle 303 is pulled out from the V-shaped groove of the limiting frame 306. Then, the handle 305 is rotated to make the baffle 303 misalign with the limiting frame 306. Then, the handle 305 is pushed towards the second receiving groove 302 to push the baffle 303 into the second receiving groove 302 for limiting. The spring 307 returns to its original state to ensure that the baffle 303 and the depth of the second receiving groove 302 are always in contact. This realizes the rapid connection between the vertical support 1 and the arc support 2 without complicated welding operations, which greatly improves the installation efficiency and saves construction time.

[0030] Next, insert the screw 602 into the socket 601, and then connect the locking nut 603 to both ends of the screw 602 to achieve the fastening effect on the vertical support 1 and the arc support 2.

[0031] Align the two ends of the handle 605 with the screw 602, insert the pin 604 into the handle 605 and the screw 602, and then rotate the handle 605. Since the handle 605 and the pin 604 are eccentrically set, the eccentric cylinder of the rotated handle 605 abuts against the locking nut 603 or the fine-tuning nut 606, which can prevent the locking nut 603 from loosening due to vibration caused by construction or transportation.

[0032] The total thickness of the locking nut 603 and the fine-tuning nut 606 can be adjusted by rotating the fine-tuning nut 606, thereby fine-tuning the tightness of the screw 602 and ensuring the tightness and reliability of the connection.

[0033] To prevent the pin 604 from disengaging from the handle 605 and the screw 602, limit strips can be inserted into both ends of the pin 604.

[0034] The remaining structure is the same as that in Example 1.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
