[0002] The steel arch frame is the main load-bearing structure of the tunnel, so the installation of the steel arch frame is an important part of the tunnel construction process. The traditional transportation operation of the steel arch frame mainly adopts manual operation.

[0052] The present invention provides a steel arch transport device, which is combined with Figures 1 to 7 The present invention is described with reference to the structural schematic diagram of FIG.

[0053] Example 1

[0054] like Figure 1 and Figure 2 As shown, a steel arch frame conveying device comprises:

[0055] The transfer platform 1 has at least one trough body 1 for accommodating the steel arch frame on its top surface, and the bottom surface of the trough body 1 and the top surface of the transfer platform 1 are both arc-shaped surfaces, and the curvature of the arc-shaped surface matches the curvature of the steel arch frame;

[0056] There are multiple clamping devices 7, which are arranged in a groove body 1 of the transfer platform 1 and are used to clamp the steel arch frame to prevent the steel arch frame from moving during transportation.

[0057] The structure of the clamping device 7 includes two groups of elastic components, which are symmetrically arranged on a pair of inner walls of the groove body. The distance between the upper ends of the two groups of elastic components is greater than the distance between the lower ends, forming a V-shaped clamping space.

[0058] Since the distance between the upper ends of the two sets of elastic components is greater than the distance between the lower ends, a V-shaped clamping space is formed between the two sets of elastic components and the trough body, which is helpful for clamping and fixing the steel arch frame.

[0059] The elastic components include a clamping plate 702, two elastic parts 1 701 and two elastic parts 2 703. The two elastic parts 1 701 and the two elastic parts 2 703 are respectively located at the four corners of the clamping plate 702, and their two ends are respectively fixedly connected to the clamping plate 702 and the inner wall of the groove body 1. The two elastic parts 1 701 are above the two elastic parts 2 703 and the elastic part 2 703 is longer than the elastic part 1 701, so that the two clamping plates 702 form a V-shaped structure, which is convenient for clamping and also convenient for the steel arch frame to slide in.

[0060] The extension plate 4 is fixedly connected to the side of the transfer platform 1 .

[0061] A manipulator is fixedly connected to the top of the extension plate 4, and the manipulator is used to realize the transportation of the steel arch frame.

[0062] Furthermore, the manipulator comprises:

[0063] The electric turntable 3 is fixed to the extension plate 4,

[0064] The mechanical arm 2 is fixed above the electric turntable 3.

[0065] The clamping portion 6 is arranged at the end of the mechanical arm 2 away from the electric turntable 3 and is used to grasp the steel arch frame.

[0066] The electric turntable 3 is used to achieve 360-degree circumferential indexing, so that the robot arm can work at any angle.

[0067] Among them, the robotic arm 2 includes:

[0068] A hydraulic cylinder 201 is vertically fixed to the electric turntable 3. When the piston rod of the hydraulic cylinder 201 is extended, the height of the mechanical arm 2 increases. When the piston rod of the hydraulic cylinder 201 is retracted, the height of the mechanical arm 2 decreases. The hydraulic cylinder 201 is used to adjust the height of the mechanical arm 2.

[0069] The hydraulic cylinder 2 202 is arranged at the top of the end of the hydraulic cylinder 1 201 away from the electric turntable 3 and is fixedly connected to the hydraulic cylinder 1 201. The center line of the hydraulic cylinder 202 is perpendicular to the center line of the hydraulic cylinder 1 201.

[0070] When the piston rod of the second hydraulic cylinder 202 is extended, the working radius of the robot arm 2 increases, and when the piston rod of the second hydraulic cylinder 202 is retracted, the working radius of the robot arm 2 decreases, which is used to adjust the working radius of the robot arm 2;

[0071] Further, such as Figure 4 As shown, the clamping portion 6 comprises:

[0072] A cross bar 601, the middle of which is vertically fixed to the piston rod of the second hydraulic cylinder 202;

[0073] There are two blocks 602, which are respectively arranged at both ends of the crossbar 601, and the ends of the blocks 602 away from the crossbar 601 are provided with grooves;

[0074] The electromagnetic adsorption head is arranged in the groove and is used for adsorbing the steel arch frame to prevent displacement of the steel arch frame during transportation.

[0075] During transportation, a plurality of steel arch frames are hoisted and placed in the trough body 1 in sequence using a folding arm crane at the prefabrication site, and the steel arch frames are clamped using a plurality of clamping plates 702 arranged inside the trough body 1 to prevent the steel arch frames from moving during transportation.

[0076] Specifically, an electromagnetic adsorption device may be provided on the clamping plate 702 to improve the positioning effect during the transportation of the steel arch frame.

[0077] Use a folding arm crane to move the transfer platform 1 as a whole to the transfer vehicle for transfer. After the transfer vehicle arrives at the inside of the tunnel, move the transfer platform 1 as a whole to the installation stand, start the manipulator, use the manipulator to lift the steel arch frame one by one, and then move it horizontally to the installation station for installation.

[0078] Example 2

[0079] In order to further improve the efficiency of the steel arch frame withdrawing from the trough body, Figure 7 As shown, trough body 2 is opened on the bottom surface of trough body 1, trough body 2 and trough body 1 form a step trough structure, and an even number of lifting structures for pushing the steel arch frame out of trough body 1 are evenly distributed on the bottom surface of trough body 2.

[0080] The lifting structure includes a lifting device 705 vertically fixed to the bottom surface of the second tank body, and the top of the lifting device 705 is fixedly connected to the top plate 704.

[0081] Specifically, the lifting device 705 can be preferably a hydraulic cylinder or a pneumatic cylinder. When the piston rod of the hydraulic cylinder or the pneumatic cylinder is extended, the steel arch frame can be pushed out from the trough body, which is convenient for the manipulator to operate. When not in use, the piston rod of the hydraulic cylinder or the pneumatic cylinder is retracted.

[0082] Example 3

[0083] On the basis of Example 2, in order to facilitate further operation, when the manipulator fails or is inconvenient to use, the steel arch frame is pushed out of the transfer platform 1, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a pushing device 8 is provided on the transfer platform 1, which is arranged in a slot body three opened on the top surface of the transfer platform 1, the opening direction of the slot body three is perpendicular to the opening direction of the slot body two, and the pushing device 8 is electrically connected to the controller of the external device.

[0084] When not in use, the moving body of the pushing device 8 is retracted and hidden in the slot body 3. When in use, the pushing device 8 is raised to push the steel arch frame to the edge of the transfer platform 1.

[0085] The structure of the pushing device 8 includes:

[0086] The dual-axis motor 801 is fixed on the edge of the transfer platform 1, and the transmission structures connected to the two output shafts of the dual-axis motor 801 have the same structure.

[0087] The transmission structure includes:

[0088] A bracket 803 fixed on the edge of the transfer platform 1, a rotating shaft 802, one end of which is connected to the output shaft of the dual-axis motor 801 through a coupling, and the other end passes through the bracket 803 and is fixed with a bevel gear 806 at its end, and the bevel gear 806 is meshed with the gear 2 805;

[0089] The inner bottom surface of the tank body 3 is fixed with a bracket 2, a bracket 3 809, which is fixed to the edge of the transfer platform 1;

[0090] The screw rod 804 is mounted between the second bracket and the third bracket 809 , and one end close to the second bracket is fixedly mounted on the second bevel gear 805 . The nut seat 807 is mounted on the screw rod 804 .

[0091] The lifting structure 808 is fixed above the nut seat 807 .

[0092] A guide groove is respectively provided on a pair of side walls of the groove body three, and the length direction of the guide groove is parallel to the length direction of the groove body three. Two lugs are clamped in the guide groove and are symmetrically fixedly connected on both sides of the nut seat 807. Driven by the nut seat 804, they can slide in the guide groove.

[0093] Furthermore, the lifting structure 808 is a multi-stage hydraulic cylinder.

[0094] During use, the lifting device 705 can be used to push the steel arch frame out of the trough body. When the lower bottom surface of the steel arch frame is flush with the top surface of the transfer platform 1, the lifting device 705 stops moving, and the jacking structure 808 is started. After the top surface of the jacking structure 808 is higher than the upper surface of the steel arch frame, the jacking structure 808 stops moving, and the dual-axis motor 801 is started synchronously to drive the two screw rods 804 to rotate synchronously. The nut seat 807 arranged thereon moves synchronously on the screw rod 804, driving the jacking structure 808 to push the steel arch frame along the top surface of the transfer platform 1 to the edge of the transfer platform 1. After pushing the steel arch frame to the edge of the transfer platform 1, the dual-axis motor 801 is started to make it rotate in the opposite direction and reset, and the jacking structure 808 is driven synchronously to retract the jacking structure 808.

[0095] Example 4

[0096] On the basis of Example 3, in order to reduce the friction coefficient between the steel arch frame and the upper surface of the transfer platform 1 during the process of pushing the steel arch frame to the edge of the transfer platform 1, as shown in FIG. Figure 3 As shown, a rolling structure is provided on the arc surface of the transfer platform 1 to reduce the friction force when the steel arch frame moves to the edge of the transfer platform 1.

[0097] Furthermore, the rolling structure includes a plurality of spherical grooves formed on the top surface of the transfer platform 1, in which balls are mounted. The balls can rotate along the spherical grooves under the action of external force or friction force.

[0098] When the steel arch frame is pushed to move to the edge of the transfer platform 1, the lower side of the steel arch frame rubs the balls, causing the balls to rotate along the spherical grooves, thereby reducing the resistance during movement.

[0099] A steel arch transport method comprises the following steps:

[0100] In the prefabrication yard, the steel arch frames are hoisted one by one and placed in the tank body 1 on the transfer platform 1, and the position of the steel arch frames is fixed by the clamping device 7;

[0101] Use a folding arm crane to move the transfer platform 1 as a whole to the transfer vehicle;

[0102] The transfer vehicle is started for transfer. After the transfer vehicle arrives inside the tunnel, the transfer platform 1 is moved as a whole to the installation stand so that the length direction of the steel arch frame is perpendicular to the length direction of the tunnel;

[0103] Synchronously start the multiple lifting structures under the steel arch frame that needs to be transported, push the steel arch frame out of the tank, and keep the lifting structure in motion;

[0104] When the robot is in normal working condition:

[0105] Start the manipulator, use the manipulator to lift the steel arch frame one by one, and then send it to the installation station for installation;

[0106] The manipulator and lifting structure are closed after being reset;

[0107] When the robot is in abnormal working state:

[0108] Start the pushing device 8, push the steel arch frame to the edge of the transfer platform 1, and then keep the pushing device 8 in motion;

[0109] With human assistance, the steel arch frame can be delivered to the installation site using a folding arm crane for installation;

[0110] The lifting structure and the pushing device 8 are closed after being reset.

[0111] Compared with the prior art, the steel arch frame transportation device provided by the present invention effectively reduces the number of operators during the transportation of the steel arch frame, reduces the labor intensity of workers, improves work efficiency, reduces the safety risk factor, has strong practicality, and is worthy of promotion.

[0112] The above disclosure is only a preferred specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
