[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0029] Reference Figures 1-9This is the first embodiment of the present invention, which provides a temporary placement and protection device for an arch frame used with a tunnel boring machine. The device includes a support unit 100, which comprises a placement platform 101, two support components 102 symmetrically fixedly installed on the top of the placement platform 101, a placement component 103 fixed to one side of the two support components 102, and a winding component 104 disposed in the placement component 103; and a shielding unit 200, which includes a canopy tarpaulin 201 disposed between the two support components 102. The support rod 202 is fixed to the side of the canopy tarpaulin 201 facing the slide rail 101a, the actuating components 203 are set at both ends of the support rod 202, and the connecting rod 204 is fixed to both ends of the support rod 202; the traction unit 300 includes two traction rods 301 symmetrically arranged on the top of the placement platform 101, two third sliders 302 fixed to one end of the traction rods 301, and a slot 303 opened at one end of the traction rods 301. The connecting rod 204 is fixed to the side of the traction rod 301 near the support component 102.

[0030] In use, the placement platform 101 is used to support the manufactured arch frame, ensuring its stable placement. The support component 102 can block the arch frame and provide a stable support point for the canopy fabric 201 to ensure the stability of the canopy fabric 201 after it is unfolded. The winding component 104 can stably wind up the canopy fabric 201, and the placement component 103 can store the canopy fabric 201. Through the cooperation of the traction unit 300, the shielding unit 200, and the supporting unit 100, the unfolding and storage operations of the canopy fabric 201 can be realized. The cooperation of the traction rod 301 and the first limiting member 101d can limit the traction rod 301 to ensure the stability of the canopy fabric 201 after it is unfolded.

[0031] When the placement platform 101 is wide, a transition support steel frame needs to be installed on its top. The transition support steel frame is similar in shape to the support assembly 102 and provides additional support. When the tarpaulin 201 is unfolded under the operation of the traction rod 301, the support rod 202 fixed to it contacts the top of the transition support steel frame, providing support for the support rod 202 and preventing damage from rainwater or snow accumulation. The transition support steel frame is positioned between the two support assemblies 102 and does not affect the normal placement of the arch frame. Through the design and coordination of the above structural components, this technology can effectively achieve the temporary placement and protection of the tunnel arch frame, improve the stability and durability of the arch frame, and provide strong support for tunnel construction. Example

[0032] Reference Figures 2-6This is the second embodiment of the present invention, which differs from the first embodiment in that: it also includes two slide rails 101a symmetrically opened on the top of the placement platform 101, two first slide grooves 101b symmetrically opened on the two side walls of the slide rails 101a, a placement groove 101c opened on the top of the placement platform 101, the two slide rails 101a are connected through the placement grooves 101c, a first limiting member 101d is provided at the end of the first slide groove 101b away from the placement component 103, and the slide rails 101a and the first slide grooves 101b are slidably engaged with the traction rod 301 and the third slider 302, respectively.

[0033] Furthermore, the first limiting member 101d includes a first groove 101d-1 formed in the placement platform 101 and adapted to the slot 303, a first through groove 101d-2 formed on the top of the first groove 101d-1, and a first spring 101d-3 and a locking block 101d-4 disposed in the first groove 101d-1. The two ends of the first spring 101d-3 are respectively fixed to one side of the first groove 101d-1 and one side of the locking block 101d-4. A push rod 101d-5 is fixedly connected to the top of the locking block 101d-4. The push rod 101d-5 slides in the first through groove 101d-2. The locking block 101d-4 is adapted to the slot 303.

[0034] The top of the placement platform 101 has a chamfer on one side to facilitate the placement and retrieval of the arch frame, improving the ease of operation. The cooperation of the slide rail 101a and the first slide groove 101b can limit the movement of the traction rod 301, ensuring that one end of the traction rod 301 slides smoothly in the slide rail 101a. The placement groove 101c is designed to facilitate the unfolding of the awning cloth 201 and its fixing by the first limiting member 101d. After this, one side of the awning cloth 201 can be combined with the placement platform 101, ensuring that the arch frame placed on the top of the placement platform 101 is covered, effectively preventing rainwater from splashing onto the arch frame and causing damage to it.

[0035] The inclined surface on the locking block 101d-4 allows it to be pressed into the first groove 101d-1 by the traction rod 301 when it comes into contact with the traction rod 301, facilitating operation and reducing steps. The first spring 101d-3 provides a stable pushing force to the locking block 101d-4, ensuring stable positioning of the traction rod 301. To release the restriction between the traction rod 301 and the locking block 101d-4, the push rod 101d-5 is pulled. The push rod 101d-5 moves the locking block 101d-4 into the first groove 101d-1, thereby releasing the restriction of the locking block 101d-4 on the traction rod 301.

[0036] The bottom of the slide rail 101a is sloped, and the placement groove 101c is higher in the middle and lower on both sides. The sloped design does not affect the movement of the traction rod 301 in the slide rail 101a. The slope gradually decreases from the middle of the placement platform 101 to the edge of the placement platform 101. Rainwater falling into the slide rail 101a and placement groove 101c is discharged through the water outlet hole opened in the placement platform 101, which prevents rainwater from accumulating in the placement groove 101c and slide rail 101a and affecting the components in the device.

[0037] Specifically, the support assembly 102 includes a support frame 102a fixed to the top of the placement platform 101, a carrier frame 102b fixed to the inner ring of the support frame 102a, a second slide groove 102c opened on the side of the support frame 102a near the center of the placement platform 101, and a third slide groove 102d opened on one side of the second slide groove 102c. A blocking member 102e is provided on the side wall of the second slide groove 102c, and two crossbars 102f are fixedly connected between the two carrier frames 102b.

[0038] Furthermore, the blocking member 102e includes a second groove 102e-1 formed on the side wall of the second groove 102c, two fourth grooves 102e-2 symmetrically formed on the two side walls of the second groove 102e-1, a fixed shaft 102e-3 fixed in the second groove 102e-1, a rotating plate 102e-4 rotatably sleeved on the outer ring of the fixed shaft 102e-3, a connecting plate 102e-6 connected to the rotating plate 102e-4 through an elastic plate 102e-5, and a first slider 102e-7 fixed on both sides of one end of the connecting plate 102e-6. The first slider 102e-7 slides in the fourth groove 102e-2.

[0039] Furthermore, a third groove 102e-8 is provided on the surface of the rotating plate 102e-4 that contacts the fixed shaft 102e-3. A first spiral spring 102e-9 is provided in the third groove 102e-8, and the two ends of the first spiral spring 102e-9 are respectively fixed to one side of the third groove 102e-8 and the outer ring of the fixed shaft 102e-3.

[0040] Due to the shape of the support component 102, when rainwater falls on the tarpaulin 201, it flows towards the lower side of the top of the support frame 102a, reducing the accumulation of rainwater. The support frame 102b can support and fix the support frame 102a, ensuring its stability. When the device is in use, since the side area of ​​the support frame 102a is small, a small tarpaulin can be used to cover it. When not in use, this small tarpaulin can be rolled up and hung on the side of the support frame 102a for easy access by staff, preventing rainwater from corroding the arch frame. The opening of the second slide groove 102c and the third slide groove 102d provides conditions for the movement of the tarpaulin 201 and limits the movement trajectory of the tarpaulin 201, ensuring the stable unfolding and retraction of the tarpaulin 201. The crossbar 102f can limit the placement of the arch frame, preventing it from swinging and causing damage, while also ensuring that the arch frame will not damage the tarpaulin after the tarpaulin 201 is unfolded.

[0041] like Figure 6 As shown, when the awning cloth 201 is unfolded, the trigger component 203 contacts the rotating plate 102e-4. Since the elastic force of the second spring 203g is greater than that of the first spiral spring 102e-9, the rotating plate 102e-4 will rotate. At this time, the first spiral spring 102e-9 will retract, causing the first slider 102e-7 to slide in the fourth slide groove 102e-2. Meanwhile, the elastic plate 102e-5 will slowly move to contact the rotating plate 102e-4 and the connecting plate 1. 02e-6 are aligned in a straight line and placed in the second groove 102e-1, which will not affect the unfolding of the awning cloth 201. When the awning cloth 201 is stored, the blocking member 102e cooperates with the trigger component 203. Due to the limitation of the rotation angle of the rotating plate 102e-4, the awning cloth 201 can be shaken to reduce the water on the awning cloth 201 and provide appropriate protection for the awning cloth 201. This prevents the awning cloth 201 from getting too wet after storage, which could cause it to become moldy or damaged.

[0042] When storing the tarpaulin 201, the support rod 202 may tilt. If the tilt is large, it needs to be manually adjusted. If the tilt is small, the obstruction of the blocking part 102e will adjust the tilt of the support rod 202 to a certain extent, ensuring that the storage is carried out in an orderly manner.

[0043] Specifically, the placement component 103 includes a storage box 103a fixed to the top of the placement platform 101, a ventilation hole 103c and a drainage channel 103b opened on the side of the storage box 103a away from the support frame 102a, a top cover 103d rotatably connected to the top of the storage box 103a by a hinge, and a latch 103e provided on the top cover 103d. Two locking plates 103f are symmetrically fixedly connected inside the storage box 103a. The locking plates 103f are adapted to the latch 103e. One side of the storage box 103a is fixed to one side of the two support frames 102a.

[0044] The drainage channel 103b allows water entering the storage box 103a to be drained, while the ventilation hole 103c ensures ventilation of the storage box 103a, allowing the tarpaulin 201 to air dry after being stored inside, thus enhancing the protection of the tarpaulin 201. One side of the top cover 103d is arc-shaped, and its curved surface contacts the outer surface of the tarpaulin 201. When it rains, rainwater flows from the tarpaulin 201 to the top cover 103d, reducing the amount of rainwater entering the storage box 103a and helping to protect the components inside the storage box 103a. Furthermore, when storing the tarpaulin 201, dirt on its outer surface can be scraped off to ensure its cleanliness. The locking buckle 103e and the locking plate 103f limit the position of the top cover 103d, ensuring its stability.

[0045] Specifically, the winding assembly 104 includes a storage slot 104a symmetrically opened on both sides of the storage box 103a, a storage rod 104b rotating around the center of the storage slot 104a, and a power component 104d symmetrically arranged on both outer sides of the storage box 103a. The storage slot 104a is connected to the second slide groove 102c through the connecting groove 104c. Both ends of the storage rod 104b penetrate the storage box 103a. The power component 104d includes a housing 104d-1 fixed to the outside of the storage box 103a and a second spiral spring 104d-2 disposed in the inner ring of the housing 104d-1. The end of the storage rod 104b is rotatably connected to the inner side of the housing 104d-1. Both ends of the second spiral spring 104d-2 are respectively fixed to the outer ring of the storage rod 104b and the inner ring of the housing 104d-1.

[0046] The canopy cloth 201 is connected to one end of the storage rod 104b and automatically rolled up by the power component 104d. The connecting groove 104c provides guidance for the unfolding and storage of the canopy cloth 201. When the canopy cloth 201 is unfolded, it will drive the second spiral spring 104d-2 to retract, giving the canopy cloth 201 a tension. After unfolding, the tension of the second spiral spring 104d-2 on the canopy cloth 201 can ensure the perfect extension of the canopy cloth 201 and prevent large-area water accumulation on the surface of the canopy cloth 201. When storing, the canopy cloth 201 can be automatically stored by the tension of the second spiral spring 104d-2.

[0047] In use, when the tarpaulin 201 is unfolded via the traction rod 301, the storage rod 104b rotates, simultaneously compressing the second spiral spring 104d-2. The support rod 202 enters the second sliding groove 102c through the connecting groove 104c. When the support rod 202 contacts the rotating plate 102e-4, it causes the rotating plate 102e-4 to rotate around the fixed shaft 102e-3. Simultaneously, the rotation of the rotating plate 102e-4 drives the connecting plate 102e-6 via the elastic plate 102e-5. During the movement, the first slider 102e-7 slides in the fourth groove 102e-2, and the elastic plate 102e-5 gradually moves to be aligned with the rotating plate 102e-4 and the connecting plate 102e-6, and is placed in the second groove 102e-1, allowing the support rod 202 to pass smoothly. After the support rod 202 at one end of the awning cloth 201 moves into the placement groove 101c, one end of the traction rod 301 contacts the inclined surface of the locking block 101d-4, and locks the locking block 101d-4. The tarpaulin 201 is fully unfolded when it is pressed into the first groove 101d-1 and the slot 303 aligns with the locking block 101d-4. Due to the action of the first spring 101d-3, the locking block 101d-4 moves into the slot 303, limiting the traction rod 301. When it needs to be folded up, the push rod 101d-5 is pushed, causing the locking block 101d-4 to move out of the slot 303. Then, the second spiral spring 104d-2 drives the folding rod 10... 4b rotates to roll up the awning fabric 201. During the rolling process, when the trigger component 203 touches the connecting plate 102e-6, due to the rotation restriction of the rotating plate 102e-4, the connecting plate 102e-6 will squeeze the pressing block 203d. Through the action of the trigger component 203, the awning fabric 201 is shaken, which can remove water stains on the awning fabric 201 and, together with the arc edge of the top cover 103d, clean the outer surface of the awning fabric 201, thus completing the storage of the awning fabric 201. Example

[0048] Reference Figures 7-8 This is the third embodiment of the present invention. This embodiment is based on the first two embodiments. This embodiment also includes a triggering component 203, which includes a fifth groove 203i opened on the outside of the support rod 202, a fourth groove 203a opened on one side of the fifth groove 203i, and a pressing block 203d disposed in the fourth groove 203a. The upper and lower sides of the fourth groove 203a are symmetrically fixedly connected with a first baffle 203b. The sides of the fifth groove 203i are symmetrically provided with a fifth sliding groove 203c. The support rod 202 is slidably engaged with the second sliding groove 102c, and the connecting rod 204 is slidably engaged with the third sliding groove 102d.

[0049] The awning 201 provides protection for the arch frame. The support rods 202 can be set according to the actual use of the awning 201 and the appropriate spacing to ensure support for the awning 201 and its load-bearing capacity. The touch component 203 can cooperate with the blocking component 102e to shake the awning 201 and clean the water accumulated on the surface of the awning 201.

[0050] With the support rods 202 in place, after the roll-up, the multiple support rods 202 will overlap, which will create a gap between the awning fabric 201 between the two support rods 202 and the awning fabric 201 that has been rolled up in the previous layer. This will ensure ventilation and provide some protection for the awning fabric 201, preventing rainwater from eroding it.

[0051] Specifically, two second stops 203e are symmetrically fixedly connected to the upper and lower sides of the extrusion block 203d, and two second sliders 203f are symmetrically fixedly connected to the other two sides of the extrusion block 203d. The second sliders 203f are slidably engaged with the fifth slide groove 203c. An impact rod 203h is fixedly connected to one side of the extrusion block 203d. A second spring 203g is movably sleeved on the outer ring of the impact rod 203h. The two ends of the second spring 203g are fixed to one side of the extrusion block 203d and one side of the fourth groove 203a, respectively. The extrusion block 203d is slidably engaged with the connecting plate 102e-6.

[0052] The movement of the extrusion block 203d can be limited by the cooperation between the second slider 203f and the fifth groove 203c. Furthermore, the cooperation between the impact rod 203h and the fourth groove 203a, and the second stop block 203e and the first baffle 203b, ensures that when the trigger component 203 contacts the blocking member 102e, it impacts the support rod 202, causing the support rod 202 to shake the awning cloth 201, thereby clearing accumulated water.

[0053] When the awning cloth 201 is stored, the squeezing block 203d will contact the connecting plate 102e-6. The connecting plate 102e-6 will drive the squeezing block 203d to slide into the fourth groove 203a. When it slides to the highest point of the connecting plate 102e-6, the impact rod 203h will hit the fourth groove 203a, causing the support rod 202 to cause the awning cloth 201 to vibrate slightly. After the trigger component 203 moves out of the range of the connecting plate 102e-6, the squeezing block 203d can be driven to return to its original position by the setting of the second spring 203g. At this time, the second stop block 203e will hit the first stop plate 203b, causing the support rod 202 to vibrate, thereby causing the awning cloth 201 to vibrate. With the setting of the top cover 103d, the outer surface of the awning cloth 201 can be cleaned.

[0054] In summary, when the awning fabric 201 is unfolded, the movable traction rod 301 moves the awning fabric 201 through the connecting rod 204 and the support rod 202. When moving the traction rod 301, it is necessary to tilt the traction rod 301 appropriately according to the height and angle of the support frame 102a. During this process, the support rod 202 and the connecting rod 204 slide in the second slide groove 102c and the third slide groove 102d respectively. During the sliding process, the trigger component 203 comes into contact with the blocking component 102e. The trigger component 203 will drive the rotating plate 102e-4, the elastic plate 102e-5 and the connecting plate 102e-6 to be placed in a straight line in the second groove 102. In e-1, ensure that the support rod 202 passes smoothly. Thus, when the traction rod 301 is fully placed in the slide rail 101a, the first limiting member 101d will limit the traction rod 301. When storing the awning cloth 201, operate the first limiting member 101d to release the restriction on the traction rod 301. The second spiral spring 104d-2 will pull the awning cloth 201. During the pulling process, when the trigger component 203 contacts the blocking member 102e, the trigger component 203 can cause the awning cloth 201 to shake and cooperate with the locking buckle 103e to clean the surface of the awning cloth 201 until the roll-up is completed.
