Description

Technical Field

[0001] This utility model relates to the field of mine safety technology, specifically a mobile temporary support folding support component for mining. Background Technology

[0002] In mining and underground operations, temporary support is a crucial measure for ensuring operational safety. Currently, commonly used temporary support devices in mines are mostly fixed or simple support structures, which suffer from problems such as inconvenience in movement, difficulty in adjustment, and large space requirements for storage. Traditional support equipment often requires multiple people to work together to transport and install, which is particularly difficult in narrow and complex underground roadways, severely impacting operational efficiency. Furthermore, these devices typically lack effective roof protection design, offering insufficient protection against falling rocks or debris, posing certain safety hazards.

[0003] Existing support components are mostly one-piece or simply disassembled structures, lacking quick-folding capabilities. For example, while some devices are equipped with casters, their overall structure remains bulky and cannot be compactly folded, making storage and transportation inconvenient when not in use. Furthermore, the canopy installation methods for most support devices are cumbersome, requiring additional tools for securing them, hindering rapid deployment or dismantling. The stability of connections also needs improvement; they are prone to loosening under uneven loads, affecting the support effect.

[0004] Therefore, in view of the shortcomings of the existing technology, there is an urgent need to design a temporary support component for mining that integrates mobility, foldability and protection, so as to achieve rapid movement, convenient adjustment and stable support, to meet the special needs of underground mining operations and improve the efficiency and safety of support operations. Utility Model Content

[0005] The purpose of this utility model is to provide a foldable support component for mobile temporary support in mining, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mobile temporary support folding support assembly for mining includes a main support and a protective canopy. A secondary support is provided below the main support, and an installation block is installed at the bottom of the secondary support. A movable roller is rotatably installed in the middle of the installation block.

[0008] A support top frame is installed above the main bracket. A limit block is welded to the inner wall of the support top frame. A threaded groove is opened on the outer wall of the limit block. A protective canopy is placed in the middle of the limit block.

[0009] Furthermore, the supporting top frame consists of two semi-circular frames. The semi-circular frames not only have good mechanical load-bearing performance and can evenly distribute the top load, but are also easy to manufacture and install.

[0010] Furthermore, connecting blocks are provided at the connection points between the supporting top frame and the main support. The design of the connecting blocks makes the connection between the main support and the secondary support more secure, effectively resisting lateral forces and vibrations, and preventing loosening or displacement during use.

[0011] Furthermore, the mounting block and the sub-support are fixedly connected by bolts on the outer wall, and the outer wall of the bolts is provided with hexagonal nuts. The use of this standardized connector facilitates replacement and maintenance, and improves the service life of the device.

[0012] Furthermore, a rotating block is provided at the connection between the bottom of the main support and the top of the secondary support. This design greatly reduces the space occupied by the device, facilitates transportation and storage in narrow mine tunnels, and improves space utilization efficiency.

[0013] Furthermore, the main support and the secondary support are welded to the outer walls with fixing blocks. When the main support and the secondary support are rotated open, they can be limited and fixed by bolts to increase safety.

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

[0015] 1. This utility model provides excellent mobility for the entire support assembly by setting a secondary support below the main support and installing a mounting block with movable rollers at the bottom of the secondary support. This design solves the problem of difficult handling of traditional support devices. The support assembly adopts a foldable design, and the main support and secondary support are connected by a rotating block, which realizes the rapid unfolding and folding of the assembly. Workers can easily push the folded support assembly to the required position, greatly improving work efficiency. The rotating installation method of the movable rollers ensures the smoothness of the movement process.

[0016] 2. This utility model uses a protective canopy to protect the staff inside, thereby effectively preventing small falling rocks from hitting the staff. The protective canopy also uses limiting blocks for quick installation. Attached Figure Description

[0024] like Figure 1-4 As shown, this utility model provides a foldable mobile temporary support assembly for mining, including a main support 1 and a protective canopy 5. A secondary support 2 is provided below the main support 1, and an installation block 7 is installed at the bottom of the secondary support 2. A movable roller 8 is rotatably installed in the middle of the installation block 7. This utility model provides good mobility for the entire support assembly by setting a secondary support 2 below the main support 1 and installing an installation block 7 with movable roller 8 at the bottom of the secondary support 2. This design solves the problem of difficult handling of traditional support devices. The support assembly adopts a foldable design. The main support 1 and the secondary support 2 are connected by a rotating block 13, which realizes the rapid unfolding and folding of the assembly. Workers can easily push the folded support assembly to the required position, which greatly improves the work efficiency. The rotating installation method of the movable roller 8 ensures the smoothness of the movement process.

[0025] A support top frame 3 is installed above the main support 1. A limit block 6 is welded to the inner wall of the support top frame 3. A threaded groove 12 is opened on the outer wall of the limit block 6. A protective canopy 5 is placed in the middle of the limit block 6. This utility model uses the protective canopy 5 to protect the staff inside, thereby effectively preventing small falling rocks from hitting the staff. The protective canopy 5 is also installed quickly by using the limit block 6.

[0026] In one implementation, the supporting top frame 3 consists of two semi-circular frames.

The combined design of the two semi-circular frames allows the supporting top frame 3 to be flexibly adjusted according to actual needs, providing sufficient support area without affecting the movement and storage performance of the device. This frame structure provides a stable supporting foundation for the protective canopy 5.

[0027] In one implementation, connecting blocks 11 are provided at the connection points between the supporting top frame 3 and the main support 1. The connecting blocks 11 are connected by bolts 9, which significantly enhances the stability and reliability of the structure. The design of the connecting blocks 11 makes the connection between the main support 1 and the secondary support 2 more secure, effectively resisting lateral forces and vibrations, and preventing loosening or displacement during use. This connection method also facilitates disassembly and maintenance; when a component is damaged, it can be replaced individually, reducing maintenance costs.

[0028] In one implementation, the mounting block 7 and the sub-support 2 are fixedly connected by bolts 9 on the outer wall. Hexagonal nuts 10 are provided on the outer wall of the bolts 9. The bolt connection allows for quick assembly and disassembly, facilitating disassembly and storage during transportation. The hexagonal nuts 10 provide a reliable anti-loosening function, ensuring the connection will not loosen under vibration. The use of this standardized connector also facilitates replacement and maintenance, extending the service life of the device.

[0029] As one implementation, a rotating block 13 is provided at the connection between the bottom of the main support 1 and the top of the auxiliary support 2. This design gives the device good folding function. The rotating block 13 allows the main support 1 and the auxiliary support 2 to rotate relative to each other, making it easy to quickly convert the device from the use state to the storage state. This design greatly reduces the space occupied by the device, making it easy to transport and store in narrow mine roadways and improving space utilization efficiency.

[0030] In one implementation, a fixing block 4 is welded to the outer wall of the main support 1 and the auxiliary support 2. The fixing block 4 has a slot in the middle. When the main support 1 and the auxiliary support 2 are rotated open, they can be fixed by bolts 9 to increase safety.
