Description

Technical Field

[0001] This utility model relates to the field of underground roadway protection technology in coal mines, and more specifically, to a retractable protective device. Background Technology

[0002] With the significant development of fully mechanized coal mining equipment in terms of complete sets, heavy-duty features, large scale, and intelligent operation, the production capacity of fully mechanized mining faces has increased substantially.

[0003] With the emergence of ultra-large working faces with an annual output of tens of millions of tons, the level of tunneling has not been improved accordingly. The contradiction of the imbalance between mining and tunneling has become increasingly prominent. The difficulty of tunneling work has increased and the tunneling team has expanded, which has brought tremendous pressure to safety management.

[0004] The main reason for the low tunneling efficiency is the imbalance between tunneling and support. Coal cutting time at the working face usually accounts for 17% to 34%, while the speed of disassembling or switching on protective devices is slow, accounting for 50% to 67% of the time, which greatly restricts the improvement of tunneling speed.

[0005] Existing tunneling technology employs alternating and intermittent tunneling and support operations, with support methods consisting of manual hand-held pneumatic drills or rock bolt drilling rigs. This results in problems such as fragmented processes, poor system integration, low levels of automation and intelligence, slow speed, high manpower requirements, and poor safety.

[0006] To adapt to rapid tunneling technology, protective operations need to be carried out simultaneously with tunneling. However, existing rock bolt drilling rigs used in coal mines cannot achieve simultaneous tunneling and protective operations, which restricts the improvement of tunneling efficiency.

[0008] To achieve the above objectives, according to one aspect of the present invention, a retractable protective device is provided, comprising: a plurality of lifting components, the plurality of lifting components being spaced apart, and the fixed ends of the lifting components being connected to the installation position; a first protective part, the first protective part being located above the plurality of lifting components and being fixedly connected to the telescopic ends of each lifting component, for lifting relative to the installation position; and a second protective part, the second protective part being located above the first protective part, the second protective part being connected to the first protective part and being movably disposed relative to the first protective part, the second protective part including a retracted state stacked on the first protective part and an unfolded state set at a predetermined angle to the first protective part.

[0009] Furthermore, one end of the second protective part is rotatably connected to the first protective part. The retractable protective device also includes a rotation drive component. The main body of the rotation drive component is connected to the telescopic end of the lifting component or the first protective part. The drive end of the rotation drive component is driven to the second protective part to drive the second protective part to rotate relative to the first protective part.

[0011] Furthermore, the rotation drive component is a first drive cylinder, the first cylinder body of the first drive cylinder is connected to the telescopic end of the lifting component, and the piston rod of the first drive cylinder is connected to the second protective part.

[0012] Furthermore, the first protective part is a first rectangular protective plate; the second protective part includes a second rectangular protective plate and a third rectangular protective plate connected sequentially along a predetermined direction, and the included angle between the second rectangular protective plate and the third rectangular protective plate is an obtuse angle; wherein, the end of the second rectangular protective plate away from the third rectangular protective plate is rotatably connected to one end of the first rectangular protective plate, and the driving end of the rotation driving component is drivenly connected to the second rectangular protective plate.

[0013] Furthermore, the second rectangular protective plate includes multiple plates that are sequentially nested along a predetermined direction, and any two adjacent plates can be telescopically arranged; the first plate among the multiple plates is rotatably connected to the first rectangular protective plate and connected to the driving end of the rotation driving component, and the last plate among the multiple plates is connected to the third rectangular protective plate.

[0014] Furthermore, the retractable protective device includes a lighting component, which is disposed on the first protective part and located on the lower side of the first protective part.

[0015] Furthermore, the lifting component includes a sleeve and a telescopic rod partially inserted into the sleeve. The lower end of the sleeve is connected to the installation position, and the upper end of the telescopic rod is connected to the first protective part.

[0016] Furthermore, the lifting component also includes a locking screw. One end of the locking screw is located outside the sleeve, and the other end of the locking screw passes through one side of the sleeve wall and reaches the inner hole of the sleeve. The locking screw is threadedly connected to the sleeve so that by rotating the locking screw, the locking screw can be made to abut or separate from the outer wall surface of the telescopic rod, so as to lock or unlock the telescopic movement of the telescopic rod.

[0017] Furthermore, the lifting component is a second drive cylinder, the second cylinder body of the second drive cylinder is connected to the position to be installed, and the piston rod of the second drive cylinder is connected to the first protective part.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 6 As shown, this utility model provides a retractable protective device, including: multiple lifting components 1, which are spaced apart, and the fixed ends of the lifting components 1 are all connected to the installation position; a first protective part 2, which is located above the multiple lifting components 1 and is fixedly connected to the telescopic ends of each lifting component 1, so as to perform lifting and lowering movements relative to the installation position; and a second protective part 3, which is located above the first protective part 2, connected to the first protective part 2 and movably arranged relative to the first protective part 2, the second protective part 3 including a retracted state stacked on the first protective part 2 and an unfolded state set at a predetermined angle to the first protective part 2.

[0036] Thus, the retractable protective device of this utility model can adjust the protective height and range according to actual needs, and can also quickly expand the protective area in emergency situations. It is not only suitable for underground coal mine operations, enabling anchor drilling rigs to carry out tunneling and protection operations simultaneously, thus improving tunneling efficiency, but also suitable for construction sites, factories, warehouses and other scenarios where the protective height and range need to be temporarily adjusted, providing more comprehensive safety protection for workers and solving the problem of the lack of a quick-opening and closing protective device in existing anchor drilling rigs.

[0037] Specifically, the retractable protective device of this utility model is applicable to anchor drilling rigs working in underground coal mine roadways, and the installation location is the body of the anchor drilling rig.

[0038] like Figures 1 to 6 As shown, one end of the second protective part 3 is rotatably connected to the first protective part 2. The retractable protective device also includes a rotation drive component 4. The main body of the rotation drive component 4 is connected to the telescopic end of the lifting component 1 or the first protective part 2. The drive end of the rotation drive component 4 is driven to connect to the second protective part 3 to drive the second protective part 3 to rotate relative to the first protective part 2.

[0039] The retractable protective device of this utility model, by setting a rotating drive component 4, enables the second protective part 3 to be quickly deployed or retracted, thereby improving the response speed and operational efficiency of the retractable protective device. It is particularly suitable for rapid protective deployment in emergency situations, and can provide immediate protective measures for sudden situations, quickly deploying to form a temporary protective space to protect workers from injury.

[0040] like Figures 1 to 4 As shown, the main body of the rotating drive component 4 is located below the first protective part 2 and is connected to the telescopic end of the lifting component 1. The drive end of the rotating drive component 4 passes through the first protective part 2 and is connected to the second protective part 3. The first protective part 2 is provided with a clearance hole 20 for avoiding the drive end of the rotating drive component 4.

[0041] The telescopic end of the lifting component 1 is provided with a transition plate 7, and the main body of the rotation drive component 4 is mounted on the transition plate 7.

[0042] Specifically, the rotation drive component 4 is a first drive cylinder, the first cylinder body of the first drive cylinder is connected to the telescopic end of the lifting component 1, and the piston rod of the first drive cylinder is connected to the second protective part 3.

[0043] The aforementioned first drive cylinder provides powerful driving force, ensuring smooth deployment and retraction of the second protective unit 3. It is suitable for protective scenarios that need to withstand large external impacts, providing a solid protective barrier for high-risk work areas. In extreme environments such as mining and chemical production, it can effectively resist possible explosion or collapse risks and protect the lives of workers.

[0044] Optionally, the first drive cylinder is a pneumatic cylinder or an electric cylinder.

[0045] like Figures 1 to 6As shown, the first protective part 2 is a first rectangular protective plate 21; the second protective part 3 includes a second rectangular protective plate 31 and a third rectangular protective plate 32 connected sequentially along a predetermined direction, and the included angle between the second rectangular protective plate 31 and the third rectangular protective plate 32 is an obtuse angle; the end of the second rectangular protective plate 31 away from the third rectangular protective plate 32 is rotatably connected to one end of the first rectangular protective plate 21, and the driving end of the rotation driving component 4 is drivenly connected to the second rectangular protective plate 31 so that the retractable protective equipment can cover a wider area, so that the surrounding workers can also be fully protected and prevent accidents such as falling objects from heights.

[0046] The end of the second rectangular protective plate 31 that is away from the third rectangular protective plate 32 is connected to one end of the first rectangular protective plate 21 by a rotating shaft component 6.

[0047] like Figure 6 As shown, the second rectangular protective plate 31 includes multiple plates 311 sequentially nested along a predetermined direction, with any two adjacent plates 311 being extendable and retractable. The first plate 311 is rotatably connected to the first rectangular protective plate 21 and connected to the drive end of the rotation drive component 4, while the last plate 311 is connected to the third rectangular protective plate 32. This extendable second rectangular protective plate 31 allows for further flexible adjustment of the protection range, making it suitable for scenarios requiring frequent adjustments to the protection area and ensuring the safety of workers during production.

[0048] like Figure 3 As shown, the retractable protective device includes a lighting component 5, which is disposed on the first protective part 2 and located on the lower side of the first protective part 2. The lighting component 5 can provide sufficient lighting, which not only improves visibility at night or in low light environments, but is also suitable for night construction or working environments with insufficient light, such as underground construction, thereby avoiding safety accidents caused by poor visibility. At the same time, its warning function can also remind operators to pay attention to safety and prevent accidents from happening.

[0049] like Figures 1 to 4 In the embodiment shown, the lifting component 1 includes a sleeve 11 and a telescopic rod 12 partially inserted into the sleeve 11. The lower end of the sleeve 11 is connected to the position to be installed, and the upper end of the telescopic rod 12 is connected to the first protective part 2.

[0050] The main body of the rotation drive component 4 is connected to the telescopic rod 12.

[0051] like Figures 1 to 4In the embodiment shown, the lifting component 1 also includes a locking screw 13. One end of the locking screw 13 is located outside the sleeve 11, and the other end of the locking screw 13 passes through one side of the sleeve 11 and reaches the inner hole of the sleeve 11. The locking screw 13 is threadedly connected to the sleeve 11 so that by rotating the locking screw 13, the locking screw 13 can abut against or separate from the outer wall surface of the telescopic rod 12, so as to lock or unlock the telescopic movement of the telescopic rod 12.

[0052] The aforementioned locking screw 13 ensures that the retractable protective device can be fixed in place after being adjusted to a suitable height. This is suitable for scenarios where the protective height needs to remain unchanged for a long time, providing stable safety for workers and preventing accidental damage from external sources. At the same time, this stable fixing method also ensures the stability of the retractable protective device during long-term use and extends its service life.

[0053] In an embodiment of this utility model (not shown), the lifting component 1 is a second drive cylinder. The second cylinder body of the second drive cylinder is connected to the installation position, and the piston rod of the second drive cylinder is connected to the first protective part 2. The use of the second drive cylinder not only improves the lifting efficiency but also enhances the load-bearing capacity of the retractable protective equipment. It is suitable for scenarios that require rapid adjustment of the protective height and have high load-bearing requirements, ensuring that the equipment can withstand additional loads even during the replacement or maintenance of large mechanical parts, providing a safer working environment for operators.

[0054] The main body of the rotation drive component 4 is connected to the piston rod.

[0055] Optionally, the second drive cylinder is a pneumatic cylinder or an electric cylinder.

[0056] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0057] The retractable protective device of this utility model includes: multiple lifting components 1, which are spaced apart, and the fixed ends of the lifting components 1 are all connected to the installation position; a first protective part 2, which is located above the multiple lifting components 1 and is fixedly connected to the telescopic ends of each lifting component 1, so as to perform lifting and lowering movements relative to the installation position; and a second protective part 3, which is located above the first protective part 2, connected to the first protective part 2 and movably arranged relative to the first protective part 2, and includes a retracted state stacked on the first protective part 2 and an unfolded state set at a predetermined angle to the first protective part 2. Thus, the retractable protective device of this utility model can adjust the protective height and range according to actual needs, and can also quickly expand the protective area in emergency situations. It is not only suitable for underground coal mine operations, enabling anchor drilling rigs to carry out tunneling and protection operations simultaneously, thus improving tunneling efficiency, but also suitable for construction sites, factories, warehouses and other scenarios where the protective height and range need to be temporarily adjusted, providing more comprehensive safety protection for workers and solving the problem of the lack of a quick-opening and closing protective device in existing anchor drilling rigs.
