Detailed Implementation

[0021] Please see Figures 1-5 This utility model provides a technical solution: a rail transit pipe support device, including a crossbar 1 and a connecting frame 2. The connecting frame 2 is fixedly connected to the upper surface of the crossbar 1. A clamping component 3 is provided on the side surface of the connecting frame 2, and a shielding component 4 is provided on the upper surface of the clamping plate 38.

[0022] The following section will explain the specific settings and functions of the clamping component 3 and the blocking component 4.

[0023] In this embodiment: the clamping assembly 3 includes an assembly plate 31, which is fixedly connected to the side surface of the connecting frame 2. A guide frame 32 is fixedly connected to the side surface of the assembly plate 31. A bidirectional lead screw 33 is rotatably connected to the inner wall of the guide frame 32. A control frame 34 is fixedly connected to the side of the bidirectional lead screw 33 away from the crossbar 1. A linkage frame 35 is threadedly connected to the surface of the bidirectional lead screw 33. A connecting arm 36 is rotatably connected to the surface of the linkage frame 35. A load-bearing frame 37 is rotatably connected to the side of the connecting arm 36 away from the linkage frame 35. A clamping plate 38 is fixedly connected to the side surface of the load-bearing frame 37.

[0024] Specifically, a slot 39 is provided on the side of the clamping plate 38 away from the crossbar 1. The clamping plate 38 can be used to clamp the viewpoint placed in the support area in the unfolded state to ensure the stability of the pipeline in the support state.

[0025] Specifically, there are two guide frames 32, which are symmetrically arranged about the vertical center line of the crossbar 1, and the guide frames 32 are in contact with the upper surface of the crossbar 1.

[0026] In this embodiment, the moving direction of the linkage frame 35 can be guided by the guide frame 32 to ensure that the linkage frame 35 moves in the specified direction.

[0027] Specifically, there are two linkage frames 35. The two linkage frames 35 are arranged symmetrically about the horizontal center line of the bidirectional lead screw 33. The linkage frames 35 can be extended to the left, right and up and down directions of the bidirectional lead screw 33, thereby pushing the connecting arm 36 to unfold.

[0028] In this embodiment: the shielding component 4 includes a guide frame 41, which is in contact with the upper surface of the clamping plate 38. A slider 42 is installed on the inner wall of the guide frame 41. Limiting blocks 43 are fixedly connected to both sides of the slider 42. A storage cavity 44 is opened on the lower surface of the slider 42. A retaining plate 45 is slidably connected to the inner wall of the storage cavity 44. A limiting spring 46 is fixedly connected to the side surface of the retaining plate 45.

[0029] In this embodiment, the movement direction of the slider 42 can be guided by the cooperation of the guide frame 41 and the limiting block 43.

[0030] Specifically, the limiting block 43 is slidably connected to the inner wall of the guide frame 41. The limiting block 43 can restrict the position of the slider 42 within the guide frame 41 to ensure the stability of the slider 42.

[0031] Specifically, there are two card plates 45, which are arranged symmetrically about the slider 42. The card plates 45 are inserted into the inner wall of the slot 39, and the limiting spring 46 is fixedly connected to the inner wall of the storage cavity 44.

[0032] In this embodiment, the positions of the slider 42, the limiting block 43 and the guide frame 41 can be locked by the locking plate 45 under the constraint of the limiting spring 46 and in conjunction with the locking groove 39.

[0033] Working principle: After placing the pipe in the clamping area of ​​the clamping plate 38, rotate the control frame 34 clockwise. The control frame 34 rotates the double-acting screw 33, which engages with the upper and lower linkage frames 35. The two linkage frames 35 unfold outwards, pushing the connecting arm 36 during unfolding. The connecting arm 36, in conjunction with the load-bearing frame 37, pushes the clamping plate 38. The clamping plate 38 moves towards the pipe along the direction of the crossbar 1. When the clamping plate 38 reaches the surface of the pipe, rotate the other side slot frame according to the above steps, so that the other side clamping plate 38 reaches the surface of the pipe. Then, under the action of the two clamping plates 38, the pipe can be clamped. After clamping the pipe, adjust the distance between the two sliders 42 so that the distance between the two sliders 42 is aligned with the two clamping plates 38, and then move the clamping plate 4... 5. Align the slot 39 and push the slider 42 downward. The slider 42 pushes the plate 45, and the inclined surface of the plate 45 contacts the edge of the slot 39. During the contact process, the limiting spring 46 is squeezed. When the plate 45 is fully inserted into the slot 39, the limiting spring 46 loses pressure and rebounds, pushing the plate 45 into the slot 39 to restrict the position of the slider 42. Then, under the action of the slider 42 and the limiting block 43, the position of the guide frame 41 can be locked to restrict the upper part of the two side clamps 38. By setting the clamping component 3 and the shielding component 4, the support device can initially constrain the position of the pipeline during support to reduce the problem of pipeline displacement during construction, which interferes with the construction personnel, and increases the functionality of the support device.
