[0009] With this solution, the support supports the flexible mold bag, and the control lever rotates around the fulcrum to raise the support to hang the flexible mold bag. The lifting part supports the fulcrum, and the lifting part controls the lever to rise or fall to adjust the height of the support, so that the support can hang the flexible mold bag to the top of the lane. With this solution, high-efficiency hanging of the flexible mold bag is achieved, and manual climbing and hanging is not required, which increases safety.

[0010] Furthermore, the support member includes a support rod and a hook, the lower end of the support rod is connected to the lever, the upper end of the support rod is connected to the hook, and the hook is used to lift the flexible mold bag to hang the flexible mold bag.

[0011] In this arrangement, the hook lifts the flexible mold bag, the lever lifts the support rod upward, and the support rod lifts the hook and the flexible mold bag, so that the flexible mold bag can be hung on the top of the lane, thereby completing the hanging of the flexible mold bag.

[0012] Furthermore, the flexible mold bag hanging device also includes a rotating shaft, which is connected to the fulcrum of the lever, and the lever rotates with the rotating shaft.

[0013] In this arrangement, the rotating shaft is connected to the fulcrum of the lever, and the rotating shaft rotates relative to the lifting part, thereby realizing the lifting and lowering of both ends of the lever, completing the process of the support member lifting the flexible mold bag to the top of the lane to hang the flexible mold bag, thereby realizing efficient hanging of the flexible mold bag.

The clamp is set at the end of the telescopic support away from the ground, and the clamp limits the rotating shaft to prevent the rotating shaft from falling from the telescopic support.

[0016] Furthermore, the clamp includes four limit rods, which are arranged at the edge of the end of the telescopic support away from the ground. The rotating shaft is arranged between the limit rods, and there are two limit rods on each side of the rotating shaft.

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0049] like Figures 1 to 4 As shown, an embodiment of the utility model provides a flexible mold bag hanging device, comprising:

[0050] A support member 10, the upper end of the support member 10 is used to lift the flexible mold bag to hang the flexible mold bag;

[0051] A lever 20, one end of the lever 20 is connected to the lower end of the support member 10, the middle portion of the lever 20 has a fulcrum, and the other end of the lever 20 is used to control the lever 20 to rotate around the fulcrum to drive the support member 10 to rise and fall;

[0052] The lifting part 30 has one end disposed on the ground and the other end supporting a fulcrum. The lifting part 30 is used to control the lifting and lowering of the lever 20 .

[0053] With this solution, the support 10 supports the flexible mold bag, and the control lever 20 rotates around the fulcrum to raise the support 10 to hang the flexible mold bag. The lifting part 30 supports the fulcrum, and the lifting part 30 controls the lever 20 to rise or fall to adjust the height of the support 10, so that the support 10 can hang the flexible mold bag to the top of the lane. With this solution, high-efficiency hanging of the flexible mold bag is achieved, and manual climbing and hanging is not required, which increases safety.

[0054] like Figure 1 As shown, the support member 10 includes a support rod 11 and a hook 12. The lower end of the support rod 11 is connected to the lever 20, and the upper end of the support rod 11 is connected to the hook 12. The hook 12 is used to lift the flexible mold bag to hang the flexible mold bag.

[0055] In this arrangement, the hook 12 lifts the flexible mold bag, the lever 20 lifts the support rod 11 upward, and the support rod 11 lifts the hook 12 and the flexible mold bag, so that the flexible mold bag can be hung on the top of the lane, thereby completing the hanging of the flexible mold bag.

[0056] like Figure 1 As shown, the flexible mold bag hanging device further includes a rotating shaft 40 , which is connected to the fulcrum of the lever 20 , and the lever 20 rotates along with the rotating shaft 40 .

[0057] In this arrangement, the rotating shaft 40 is connected to the fulcrum of the lever 20, and the rotating shaft 40 rotates relative to the lifting part 30, thereby realizing the lifting and lowering of both ends of the lever 20, completing the process of lifting the support member 10 to the top of the tunnel to hang the flexible mold bag after the support member 10 picks up the flexible mold bag, thereby realizing the efficient hanging of the flexible mold bag.

[0058] like Figure 1 As shown, the lifting part 30 includes a telescopic support 31 and a clamp 32 . The telescopic support 31 is arranged on the ground, and the clamp 32 is arranged at one end of the telescopic support 31 away from the ground. The clamp 32 is used to limit the rotating shaft 40 .

[0059] In this way, the length of the telescopic support 31 can be adjusted, and the height of the lever 20 can be adjusted by adjusting the length of the telescopic support 31, so as to achieve accurate hanging of the flexible mold bag. The clamping claw 32 is arranged at the end of the telescopic support 31 away from the ground, and the clamping claw 32 limits the rotating shaft 40 to prevent the rotating shaft 40 from falling from the telescopic support 31.

[0060] The rotating shaft 40 is arranged at one end of the telescopic support 31, but is not connected to the telescopic support 31. When the flexible mold bag hanging device is moved in the tunnel, the lever 20 and the lifting part 30 can be moved separately to avoid the flexible mold bag hanging device being large and difficult to carry. The space in the tunnel is small, and the flexible mold bag hanging device can be carried separately to save space.

[0061] like Figure 4 As shown, the clamp 32 includes four limit rods 321, and the four limit rods 321 are arranged on the edge of the end of the telescopic support 31 away from the ground. The rotating shaft 40 is arranged between the limit rods 321, and there are two limit rods 321 on both sides of the rotating shaft 40. The limit rods 321 stop the rotating shaft 40 to prevent the rotating shaft 40 from detaching from the lifting part 30.

[0062] In this way, four limit rods 321 are set at the four corners of the telescopic support 31, and the rotating shaft 40 is set between the limit rods 321. There are two limit rods 321 on both sides of the rotating shaft 40 to stop the rotating shaft 40, so that during use, the rotating shaft 40 can only rotate at the top of the telescopic support 31 and cannot be detached from the top of the telescopic support 31, and the rotating shaft 40 is prevented from rotating in the horizontal direction, thereby avoiding the rotating shaft 40 and the lever 20 from becoming unstable and falling off during use.

[0063] like Figure 1 As shown, the telescopic support 31 includes a single support 311 and a piston 312. One end of the single support 311 is fixed to the ground, and the other end of the single support 311 is movably connected to the piston 312. The piston 312 is telescopic to drive the lever 20 to move up and down.

[0064] With such arrangement, the piston 312 is extended and retracted relative to the single support 311 to change the length of the telescopic support 31, so that the telescopic support 31 drives the lever 20 to move up and down, completing the process of picking up the flexible mold bag and hanging the flexible mold bag to the top of the lane, thereby realizing efficient hanging of the flexible mold bag.

[0065] Furthermore, the telescopic support 31 further includes an injection gun. A receiving cavity is provided between the single support 311 and the piston 312. The injection gun injects liquid into the receiving cavity to drive the piston 312 to extend.

[0066] With such a configuration, the injection gun can inject liquid into the accommodation cavity between the single pillar 311 and the plunger 312 to drive the plunger 312 to extend, and the plunger 312 extends to lift the lever 20. When the plunger 312 rises to a suitable height, the injection gun stops injecting liquid into the accommodation cavity, and the plunger 312 stops rising. At this time, the operating lever 20 lifts the flexible mold bag at the upper end of the support member 10 to the top of the lane for hanging.

[0067] Furthermore, the telescopic support 31 also includes a drain valve, which is connected to the accommodating chamber. The drain valve is closed to seal the accommodating chamber, and the drain valve is opened to release the liquid in the accommodating chamber to drive the piston 312 to retract.

[0068] With such arrangement, when the flexible mold bag is hung on the top of the laneway, the liquid in the containing chamber is slowly released through the liquid release valve, so that the piston 312 is retracted into the telescopic support 31, and the lever 20 descends with the descent of the piston 312.

[0069] like Figure 1 As shown, the flexible mold bag hanging device further includes an auxiliary ring 50 , which is disposed at one end of the lever 20 away from the supporting member 10 , and is used to pull the lever 20 to rotate.

[0070] In this way, the auxiliary ring 50 is set at the end of the lever 20 away from the support member 10. By pulling the auxiliary ring 50, the support member 10 and the flexible mold bag lifted by the support member 10 can be lifted to the top of the tunnel, thereby hanging the flexible mold bag on the top of the tunnel.

[0071] Furthermore, the flexible mold bag hanging device further comprises a traction rope, which is connected to the auxiliary ring 50 , and a person pulls the traction rope to drive the lever 20 to rotate.

[0072] One end of the traction rope is connected to the auxiliary ring 50, and a person pulls the other end of the traction rope to pull down the end of the lever 20 away from the support member 10, and the support member 10 is simultaneously lifted upward, thereby lifting the flexible mold bag to the top of the tunnel.

[0073] like Figure 1As shown, the flexible mold bag hanging device further includes a handle 60 , and the lifting part 30 can be lifted by pulling the handle 60 , thereby realizing convenient movement of the lifting part 30 and improving the carrying efficiency.

[0074] The principle of this solution is that a support 10 is provided to lift the flexible mold bag, the lower end of the support 10 is connected to a lever 20, and the support 10 can be lifted up by controlling the end of the lever 20 away from the support 10, so that the flexible mold bag is hung on the top of the lane. The lifting part 30 is connected to the fulcrum of the lever 20, and the height of the lever 20 can be adjusted by lifting and lowering the lifting part 30.

[0075] The advantages of the utility model are:

[0076] 1. In the prior art, the flexible mold bag is hung on the top of the tunnel by manually climbing up. Because the ground of the tunnel is uneven, it is easy to cause people to stand unsteadily and fall. In addition, the workload of carrying the climbing tools is large, and the space in the tunnel is small. The support member 10 is lifted by the lever 20 to hang the flexible mold bag, which not only improves the work efficiency, but also improves the safety of the work of the personnel.

[0077] 2. A clamping claw 32 is provided at one end of the telescopic support 31, and the clamping claw 32 limits the rotation shaft 40, so as to prevent the rotation shaft 40 from sliding off the top of the telescopic support 31 during the rotation of the lever 20. Four limiting rods 321 are provided, and two limiting rods 321 are provided on both sides of the rotation shaft 40, so as to prevent the rotation shaft 40 from sliding off the telescopic support 31 and also prevent the rotation shaft 40 from rotating in the horizontal direction.

[0078] 3. The support member 10, the lever 20 and the rotating shaft 40 are arranged as one body, and are arranged separately from the lifting part 30, so that the lifting part 30 can be transported separately, and the support member 10, the lever 20 and the rotating shaft 40 are transported as one body, so that the space required for transportation is small, and the flexible mold bag hanging device can be smoothly transported in a narrow well.
