[0017] Example: Figures 1 to 7 As shown, the auxiliary device for subway station roof construction in this embodiment is used to stably clamp the roof of the subway station during hoisting, ensuring the safety of the roof during the clamping process.

[0018] Specifically, the auxiliary device for subway station roof construction in this embodiment includes a mounting frame 101, and two sets of extension arms 103 are obliquely slidably provided on both sides of the mounting frame 101. The heights of the extension arms 103 in the same set are consistent, but the two sets of extension arms 103 are at different heights, and the two extension arms 103 on the same side of the mounting frame 101 are staggered. Figure 2 As shown, taking the two extension arms 103 located on the left side of the mounting frame 101 as an example, the two extension arms 103 belong to different groups of extension arms and are located at different heights.

[0019] A guide rod 102 is mounted on the inner wall of the mounting frame 101 and is slidably connected to an extension arm 103. A clamping plate 104 is mounted on the end of the extension arm 103 away from the guide rod 102. An L-shaped support plate 105 is mounted on the bottom of the clamping plate 104. The L-shaped support plate 105 matches the structure of the top plate. The horizontal plate portion at the bottom of the L-shaped support plate 105 can be supported on the bottom surface of the top plate, while the vertical plate portion of the clamping plate 104 can clamp the top plate from both sides. In this embodiment, Figure 6 As shown, in order to improve the connection performance between the clamping plate 104 and the L-shaped support plate 105, a reinforcing rib 106 is connected between the two to ensure that the clamping plate 104 and the L-shaped support plate 105 can be connected and fixed to form an integral structure, thereby improving the clamping effect on the top plate.

[0020] A control block 5 is mounted on either side of the mounting frame 101. A push mechanism 7 is located within the control block 5, which is used to push the control block 5. A control mechanism 6 is located within the control block 5, which is used to monitor the sliding of the top plate, adjust the clamping force of the clamping plate 104 on the top plate, and control the push mechanism 7. A lifting mechanism 3 is installed on the mounting frame 101, which is used to drive the control block 5 up and down.

[0021] The regulating block 5 is connected to an elastic mechanism 4, which is used to elastically pressurize the regulating block 5. A driving mechanism 2 is provided in the mounting frame 101, which is used to drive the extension arm 103 to move and drive the lifting mechanism 3.

[0022] In this embodiment, if Figure 5 As shown, the control mechanism 6 includes a control chamber 601 defined within the control block 5. A fixed rod 602 is mounted within the control chamber 601, on which a movable seat 603 is slidably mounted. A second elastic member 604, such as a spring, is disposed between the inner wall of the control chamber 601 and the movable seat 603. A rotating rod 605 is rotatably mounted on the movable seat 603, and a rotating roller 606 is mounted on the rotating rod 605. A pressure sensor 608 is disposed within the control chamber 601.

[0023] When relative sliding occurs between the hoisted top plate and the clamping plate 104, the roller 606 contacts the top of the top plate, and the friction force drives the roller 606 to move, thereby driving the movable seat 603 to move along the fixed rod 602 and squeeze the second elastic member 604. When the movable seat 603 contacts the pressure sensor 608, the controller will receive a signal, indicating that the top plate is sliding at this time and the clamping force of the clamping plate 104 is insufficient. At this time, the driving mechanism 2 will continue to drive the extension arm 103 to move along the guide rod 102 toward the mounting frame 101, that is, further retract toward one side of the top plate, thereby increasing the clamping force of the clamping plate 104 on both sides of the top plate, so that the clamping force of the top plate that slides during the hoisting process can be adjusted in time to ensure that the top plate is clamped, thereby avoiding the top plate from falling during the hoisting process and causing a major safety accident.

[0024] Since the roller 606 is set on the rotatable rotating rod 605, during the process of clamping and fixing the top plate, the roller 606 of the control mechanism 6 will contact the top of the top plate in advance under the action of the elastic mechanism 4. As the clamping plate 104 clamps the top plate, the roller 606 and the top plate may slide relative to each other left and right. The existence of the roller 606 can reduce the resistance of the top plate during lateral movement.

[0025] In addition, the control cavities 601 in the regulating blocks 5 on both sides of the mounting frame 101 are set at different positions, with the control cavity 601 in the regulating block 5 on one side being located at the front end and the control cavity 601 in the regulating block 5 on the other side being located at the rear end. Therefore, when the top plate and the clamping plate 104 slide horizontally back and forth, the roller 606 on one side will move due to the sliding of the top plate, while the roller 606 on the other side cannot move due to the restriction of the inner wall of the control cavity 601, so that the roller 606 on this side can limit the movement of the top plate due to the friction between the roller 606 and the top plate, thereby achieving a certain anti-slip effect.

[0026] In this embodiment, if Figure 5 As shown, the pushing mechanism 7 includes a pushing cavity 701 opened in the regulating block 5 , a telescopic member 702 , such as a hydraulic rod, is installed in the pushing cavity 701 , and a pushing plate 703 is installed on the telescopic member 702 .

[0027] When the movable seat 603 of the control mechanism 6 contacts the pressure sensor 608, the controller receives the signal and, in addition to starting the driving mechanism 2, also starts the telescopic member 702. The telescopic member 702 extends to move the ejecting plate 703, and the ejecting plate 703 begins to support the top of the top plate. At the same time, due to the support of the ejecting plate 703 on the top plate, the distance between the regulating block 5 and the top plate becomes longer, causing the roller 606 to separate from the top plate. At this time, under the elastic force of the second elastic member 604, the movable seat 603 is reset, and then the telescopic member 702 contracts to reset the ejecting plate 703, and the roller 606 will contact the top plate again, so that the control mechanism 6 can restart monitoring the sliding condition of the top plate, thereby improving the monitoring accuracy.

[0028] In addition, since the ejector plate 703 supports the top of the top plate, the regulating block 5 will rise relative to the top plate, thereby squeezing the elastic mechanism 4, so that the elastic pressure applied by the ejector plate 703 on the top plate is greater, thereby further increasing the clamping force on the top plate up and down, and playing a role in suppressing the sliding of the top plate.

[0029] In this embodiment, a first rubber anti-slip strip 107, a second rubber anti-slip strip 607, and a third rubber anti-slip strip 704 are respectively provided on the clamping plate 104, the rotating roller 606, and the ejecting plate 703. The first rubber anti-slip strip 107, the second rubber anti-slip strip 607, and the third rubber anti-slip strip 703 protect the surface of the ejecting plate and increase the friction between the clamping plate 104, the rotating roller 606, and the ejecting plate 703 and the ejecting plate, thereby improving the stability of the clamping fixation.

[0030] In this embodiment, if Figure 2 As shown, the driving mechanism 2 includes a driving rod 201 rotatably mounted in the mounting frame 101, a gear 203 is mounted on the driving rod 201, a rack 204 meshing with the gear 203 is mounted on the side of the extension arm 103 close to the driving rod 201, and a driving motor 202 is mounted on the top of the mounting frame 101, and the output end of the driving motor 202 is connected to the driving rod 201.

[0031] Driven by the driving motor 202, the driving rod 201 will rotate, and the gear 203 will be driven to rotate during the rotation of the driving rod 201. The gear 203 engages with the rack 204 to drive the extension arm 103 to move along the guide rod 102, thereby adjusting the position of the clamping plate 104, making it convenient for the clamping plate 104 to clamp and fix the two sides of the top plate. Moreover, due to the oblique setting of the extension arm 103, when the extension arm 103 is extended and retracted, the spacing between the clamping plates 104 on both sides of the mounting frame 101 will change. At the same time, the spacing between the clamping plates 104 on the same side of the mounting frame 101 will also change, so that the clamping position of the clamping plate 104 can be adjusted according to the size of the top plate, making the clamping more flexible.

[0032] In this embodiment, if Figure 3 As shown, the lifting mechanism 3 includes limit rods 305 installed on both sides of the top of the mounting frame 101, and a limit plate 306 is installed on the top of the limit rod 305. A lifting bracket 304 that penetrates into the mounting frame 101 is slidably provided on the limit rod 305, and a lifting plate 302 that is slidably connected to the inner wall of the mounting frame 101 is installed at the end of the lifting bracket 304. A threaded groove 301 is provided on the top of the driving rod 201, and the threaded groove 301 is threadedly connected to the lifting plate 302. A stopper 303 is installed on the inner wall of the mounting frame 101.

[0033] During the process of clamping the top plate, the threaded groove 301 on the driving rod 201 will also drive the lifting plate 302 to descend, causing the lifting bracket 304 to descend, thereby driving the regulating block 5 to descend, so that the control mechanism 6 on the regulating block 5 contacts the top of the top plate.

[0034] In this embodiment, if Figure 3 As shown, the elastic mechanism 4 includes a support base 401 connected to the lifting bracket 304, a sliding rod 402 connected to the regulating block 5 is slidably provided on the support base 401, a connecting plate 403 is installed on the top of the sliding rod 402, and a first elastic member 404, such as a spring, is provided between the connecting plate 403 and the support base 401.

[0035] Since the lifting mechanism 3 will also drive the control mechanism 6 on the regulating block 5 to contact the top of the top plate during the process of clamping the top plate, and the clamping plate 104 has not yet completed the clamping of both sides of the top plate, as the driving mechanism 2 continues to drive the extension arm 103 to move, the lifting mechanism 3 continues to move; in this process, since the control mechanism 6 on the regulating block 5 contacts the top of the top plate, the first elastic member 404 will be stretched, so that the control mechanism 6 can apply elastic force to the top of the top plate, and cooperate with the L-shaped support plate 105 to increase the clamping force on the upper and lower parts of the top plate, making the clamping of the top plate more stable.

[0036] In this embodiment, combined with Figure 1 and Figure 7 As shown, a top connecting frame 8 is installed on the top of the mounting frame 101, and two groups of symmetrically distributed lifting rings 9 are provided on the top connecting frame 8, and each group of lifting rings 9 is symmetrically distributed. Through the multiple lifting rings 9 on the connecting frame, the device can be connected to the lifting equipment to realize the lifting of the top plate.

[0037] When applied, this embodiment includes the following working principles: When the top plate needs to be hoisted, the top plate is first placed in the middle of the clamping plates 104 on both sides of the mounting frame 101, and the mounting frame 101 is located in the middle of the top plate. Then, the extension arms 103 on both sides of the mounting frame 101 are driven by the driving mechanism 2 to move into the mounting frame 101, so that the clamping plates 104 on both sides begin to tighten and clamp and fix the two sides of the top plate. At the same time, with the cooperation of the L-shaped supporting plates 105 at the bottom of the clamping plates 104, the bottom of the top plate can be supported and protected to prevent the top plate and the clamping plates 104 from sliding longitudinally. In the process of driving the driving mechanism 2, the lifting mechanism 3 will also synchronously drive the regulating block 5 to descend, and under the action of the elastic mechanism 4, the control mechanism 6 will elastically press the top of the top plate, and with the cooperation of the L-shaped supporting plates 105, the clamping force on the top plate can be increased, making the clamping of the top plate more stable. After that, the device can be connected to the lifting equipment for hoisting.

[0038] During the hoisting process, when the clamping force of the clamping plate 104 on the top plate is not enough, resulting in lateral sliding between the top plate and the clamping plate 104, the control mechanism 6 will be triggered, so that the driving mechanism 2 continues to drive the extension arm 103 to move into the mounting frame 101, thereby increasing the clamping force of the clamping plate 104 on both sides of the top plate, and also starts the jacking mechanism 7, so that the jacking mechanism 7 starts to press the top of the top plate, and the control mechanism 6 starts to separate from the top plate to achieve reset, wherein the jacking mechanism 7 pushes the elastic mechanism 4 so that the jacking mechanism 7 pushes the top plate The elastic pressure applied is greater, which can further increase the clamping force on the upper and lower parts of the top plate, thereby playing a role in suppressing the sliding of the top plate. If the sliding of the top plate can still be detected after the control mechanism 6 is reset, the driving mechanism 2 will continue to drive the extension arm 103 and gradually increase the clamping force on the top plate until there is no relative sliding between the top plate and the clamping plate 104, thereby effectively realizing the monitoring of the sliding situation during the lifting process of the top plate, and when the top plate slides, the clamping force of the clamping plate 104 on the top plate can be adjusted in time to avoid the top plate from falling during the lifting process and causing a major safety accident.

[0039] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, so they are not described in detail here.
