[0034] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present invention, "a plurality of" means two or more unless otherwise clearly and specifically defined.

[0035] As Figures 1-5 shown, the present invention provides a pipeline installation device for temporary fire protection at the construction site, including a base 10 and a control cabinet. It also includes a guide rail 11, a moving plate 12, a first driving mechanism 20, an electric turntable 30, a clamping mechanism 40 and a second driving mechanism 50.

[0036] The guide rail 11 is fixedly installed on the base 10 along the transverse direction.

[0037] The moving plate 12 is arranged on the guide rail 11 and is slidably connected to the guide rail 11.

[0038] The first driving mechanism 20 is used to control the sliding of the moving plate 12 on the guide rail 11.

[0039] The electric turntable 30 is arranged on the moving plate 12 and is rotatably connected to the moving plate 12. The electric turntable 30 is electrically connected to the control cabinet.

[0040] The number of the clamping mechanisms 40 is two. The two clamping mechanisms 40 are respectively arranged on both sides of the electric turntable 30. The clamping mechanism 40 includes a fixed rod 41, a movable rod 42, a fixed seat 43, a guide rod 44, a movable seat 45, a spring 46 and a clamping assembly 47. The fixed rod 41 is fixedly installed on the electric turntable 30 along the longitudinal direction. The movable rod 42 is arranged on the fixed rod 41 along the longitudinal direction and is slidably connected to the fixed rod 41. The fixed seat 43 is fixedly installed on the top of the movable rod 42. The guide rod 44 is fixedly installed on the fixed seat 43 along the transverse direction. The movable seat 45 is arranged on the guide rod 44 and is slidably connected to the guide rod 44. The number of the springs 46 is two. The two springs 46 are respectively sleeved on both ends of the guide rod 44. The two ends of the spring 46 are respectively fixedly connected to the fixed seat 43 and the movable seat 45. The spring 46 makes the movable seat 45 tend to be close to the middle of the guide rod 44. The clamping assembly 47 is arranged on the movable seat 45 and is used for clamping the end of the U-shaped tube 90.

[0041] The second driving mechanism 50 is used to control the two movable rods 42 to move up and down alternately.

[0042] In the initial state, due to the action of the spring 46, the movable seat 45 is located in the middle of the guide rod 44.

[0043] The specific working process of this equipment is as follows: First, the staff respectively clamp the two ends of the U-shaped tube 90 through the two clamping assemblies 47. Then, according to the actual on-site environment of the construction site, the staff can respectively control the first driving mechanism 20, the second driving mechanism 50 and the electric turntable 30 to start. When the first driving mechanism 20 starts, the two clamping mechanisms 40 can drive the U-shaped tube 90 to move back and forth; when the second driving mechanism 50 starts, the two movable rods 42 will move up and down alternately. Under the action of the fixed seat 43, the guide rod 44 and the movable seat 45, the two ends of the U-shaped tube 90 will swing up and down, so as to present an inclined state; when the electric turntable 30 starts, the U-shaped tube 90 will rotate. Therefore, this equipment can change and adjust the position and posture of the U-shaped tube 90.

[0044] In this device, two clamping mechanisms 40 can respectively clamp the two ends of the U-shaped tube 90. Under the action of the first driving mechanism 20, the second driving mechanism 50 and the electric turntable 30, this device can drive the U-shaped tube 90 to move forward and backward, swing up and down, and rotate respectively, changing and adjusting the position and posture of the U-shaped tube 90, so as to help the staff quickly install the U-shaped tube 90.

[0045] In one embodiment, the first driving mechanism 20 includes a first lead screw 21 and a first motor 22. The first lead screw 21 is arranged horizontally. The first end of the first lead screw 21 is inserted into the moving plate 12 and is threadedly connected to the moving plate 12. The second end of the first lead screw 21 is rotatably connected to the base 10. The first motor 22 is fixedly installed on the base 10 and is used to control the rotation of the first lead screw 21. The first motor 22 is electrically connected to the control cabinet.

[0046] When the first driving mechanism 20 is started, the control cabinet controls the first motor 22 to start. The first motor 22 drives the first lead screw 21 to rotate. Since the first end of the first lead screw 21 is threadedly connected to the moving plate 12, under the action of the guide rail 11, the moving plate 12 will move forward and backward. The structure of the first driving mechanism 20 is simple, which is convenient for manufacturing and use.

[0047] In one embodiment, the second driving mechanism 50 includes a fixing plate 51, a rotating rod 52 and a second motor 53. The fixing plate 51 is fixedly installed on the electric turntable 30 longitudinally. The middle of the rotating rod 52 is rotatably connected to the fixing plate 51. Waist-shaped grooves 54 are respectively formed at both ends of the rotating rod 52. Guide posts 55 are arranged in the waist-shaped grooves 54. The guide posts 55 are connected to the corresponding movable rods 42 and are also in contact with the inner walls of the waist-shaped grooves 54. The second motor 53 is fixedly installed on the fixing plate 51 and is used to control the rotation of the rotating rod 52. The second motor 53 is electrically connected to the control cabinet.

[0048] When the second driving mechanism 50 is started, the control cabinet controls the second motor 53 to start. The second motor 53 drives the rotating rod 52 to rotate. The two waist-shaped grooves 54 will respectively drive the corresponding guide posts 55 to move up and down, and then drive the two movable rods 42 to move up and down alternately. Under the action of the fixed seat 43, the guide rod 44 and the movable seat 45, the two ends of the U-shaped tube 90 will swing up and down, thus presenting an inclined state. The structure of the second driving mechanism 50 is simple, which is convenient for manufacturing and use.

[0049] In one embodiment, the guide posts 55 are rotatably connected to the corresponding movable rods 42 and are also in rolling contact with the inner walls of the waist-shaped grooves 54. In this way, when the second driving mechanism 50 is started, the guide posts 55 will roll on the inner walls of the waist-shaped grooves 54, thereby reducing the friction between the two, making the operation of this device smoother.

[0050] In one embodiment, the clamping assembly 47 includes two arc-shaped members 471, which are arranged in mirror symmetry, and the opening directions of the two arc-shaped members 471 are both inward. The inner wall of the arc-shaped member 471 is adapted to the end of the U-shaped tube 90. The first end of the arc-shaped member 471 is rotatably connected to the movable rod 42, and the second end of the arc-shaped member 471 is a free end. A torsion spring 472 is arranged between the arc-shaped member 471 and the movable rod 42, and the two ends of the torsion spring 472 are respectively fixedly connected to the arc-shaped member 471 and the movable seat 45, and the torsion spring 472 makes the second end of the arc-shaped member 471 have a tendency to swing inward.

[0051] When the device is in use, the staff inserts the end of the U-shaped tube 90 into the two arc-shaped pieces 471 . Under the action of the torsion spring 472 , the two arc-shaped pieces 471 will tightly embrace the end of the U-shaped tube 90 , thereby clamping the end of the U-shaped tube 90 .

[0052] In one embodiment, an arc-shaped guide surface 473 that is inclined inward and extends inward is formed on the outer end surface of the arc-shaped member 471 .

[0053] This design allows the device to clamp the U-shaped tube 90 by simply placing the U-shaped tube 90 horizontally, then placing the two ends of the U-shaped tube 90 into the corresponding arc-shaped guide surfaces 473, and finally pushing the U-shaped tube 90 forward to complete the clamping of the U-shaped tube 90.

[0054] In the process of pushing the U-shaped tube 90 forward, the U-shaped tube 90 will first contact the arc-shaped guide surface 473. Under the guidance of the arc-shaped guide surface 473, the arc-shaped member 471 will gradually swing outward until the end of the U-shaped tube 90 contacts the inner wall of the arc-shaped member 471. At this time, under the action of the torsion spring 472, the two arc-shaped members 471 will tightly hold the end of the U-shaped tube 90.

[0055] This design enables the two arc pieces 471 to automatically hold the ends of the U-shaped tube 90 , eliminating the need for staff to manually pry apart the two arc pieces 471 and then place the ends of the U-shaped tube 90 into the two arc pieces 471 , further facilitating use by staff.

[0056] In one embodiment, it further includes a limiting mechanism 60 , a lifting mechanism 70 and a pushing mechanism 80 .

[0057] The limiting mechanism 60 includes a U-shaped plate 61, which is fixedly mounted on the base 10 along the longitudinal direction, and a U-shaped groove extending downward is formed on the top of the U-shaped plate 61, and the U-shaped groove is adapted to the U-shaped tube 90. A plurality of U-shaped tubes 90 are arranged in the U-shaped groove, and the plurality of U-shaped tubes 90 are arranged in sequence along the longitudinal direction.

[0058] The lifting mechanism 70 is used to lift all the U-shaped tubes 90 in the U-shaped groove.

[0059] The pushing mechanism 80 is used to push the two end parts of the uppermost U-shaped tube 90 into the corresponding clamping components 47 respectively.

[0060] In the initial state, multiple U-shaped tubes 90 are placed in the U-shaped groove.

[0061] The specific process of this device clamping the U-shaped tube 90 is as follows: The lifting mechanism 70 is started, and multiple U-shaped tubes 90 are synchronously lifted by a certain distance until the uppermost U-shaped tube 90 leaves the U-shaped groove. Then the pushing mechanism 80 is started, and the uppermost U-shaped tube 90 is pushed forward until both ends of the U-shaped tube 90 come into contact with the corresponding arc-shaped guiding surfaces 473 respectively. Under the guiding action of the arc-shaped guiding surfaces 473, the arc-shaped parts 471 will gradually swing outwards until the end part of the U-shaped tube 90 comes into contact with the inner wall of the arc-shaped part 471. At this time, under the action of the torsion spring 472, the two arc-shaped parts 471 will tightly hold the end part of the U-shaped tube 90, thus completing the clamping of the U-shaped tube 90.

[0062] Therefore, after the staff installs one U-shaped tube 90, this device can automatically clamp another U-shaped tube 90 to facilitate continuous installation, further facilitating the use of the staff.

[0063] In one embodiment, the lifting mechanism 70 includes a top plate 71, a lifting plate 72, a second lead screw 73 and a third motor 74. The top plate 71 is arranged horizontally above the U-shaped plate 61 and is fixedly connected to the base 10 through a vertical rod 75. The lifting plate 72 is arranged in the U-shaped groove and is slidably connected to the vertical rod 75. The second lead screw 73 passes through the lifting plate 72 longitudinally and is threadedly connected to the lifting plate 72. The two ends of the second lead screw 73 are respectively rotatably connected to the base 10 and the top plate 71. The third motor 74 is fixedly installed on the top plate 71 and is used to control the rotation of the second lead screw 73. The third motor 74 is electrically connected to the control cabinet.

[0064] When the lifting mechanism 70 works, the control cabinet controls the third motor 74 to start. The third motor 74 drives the second lead screw 73 to rotate. Under the action of the vertical rod 75, the lifting plate 72 will move upwards until the uppermost U-shaped tube 90 leaves the U-shaped groove. This structure of the lifting mechanism 70 is simple and convenient for manufacturing and use.

[0065] In one embodiment, the pushing mechanism 80 includes an L-shaped plate 81 and a cylinder 82. The L-shaped plate 81 is fixedly installed on the U-shaped plate 61. The cylinder 82 is arranged horizontally and is electrically connected to the control cabinet. The cylinder body of the cylinder 82 is fixedly installed on the L-shaped plate 81, and a push plate 83 is fixedly installed on the piston rod of the cylinder 82.

[0066] In the initial state, the cylinder 82 is in a contracted state.

[0067] When the pushing mechanism 80 is working, the control cabinet controls the cylinder 82 to start. The piston rod of the cylinder 82 extends, and the push plate 83 will push the uppermost U-shaped tube 90 forward.

[0068] In one embodiment, the pushing mechanism 80 further includes two L-shaped limiting plates 84. The two L-shaped limiting plates 84 are respectively arranged on both sides of the U-shaped plate 61. The first side of the L-shaped limiting plate 84 is fixedly connected to the outer wall of the U-shaped plate 61, and the second side of the L-shaped plate 81 is located above the U-shaped tube 90.

[0069] The design of the two L-shaped limiting plates 84 plays a role in limiting the uppermost U-shaped tube 90. When the lifting mechanism 70 starts, the uppermost U-shaped tube 90 leaves the U-shaped groove, and the piston rod of the cylinder 82 extends. Then the push plate 83 will push the uppermost U-shaped tube 90 forward. During the pushing process, due to the limiting effect of the two L-shaped limiting plates 84, this U-shaped tube 90 will move forward stably without shaking left and right, so as to ensure that both ends of the U-shaped tube 90 accurately contact the corresponding arc-shaped guide surfaces 473 respectively.
