DETAILED DESCRIPTION
[0037] The utility model will be further explained in detail in combination with the drawings. These drawings are all simplified schematic diagrams, and only the basic structure of the utility model is schematically shown, so it only shows the structure related to the utility model.
[0038] Example One
[0039] As Figures 1-5 shown in the specific embodiment of the manual rail passing device of the utility model, it comprises first docking mechanism 3 and second docking mechanism 4 respectively rotatably installed on first track 1 and second track 2. Wherein, first docking mechanism 3 comprises triangular rail passing plate 31 rotatably installed on first track 1, limiting stop lever 32 installed on triangular rail passing plate 31, first rope 35 with one end connected to triangular rail passing plate 31 and second rope 36 with one end connected to the docking surface of triangular rail passing plate 31.
[0040] It needs to be further explained that when first track 1 and second track 2 are converted from the open state to the closed state, first rope 35 is pulled to drive triangular rail passing plate 31 to rotate until the docking surface of triangular rail passing plate 31 is separated from second docking mechanism 4, and until the docking surface of triangular rail passing plate 31 is parallel to Z axis. When first track 1 and second track 2 are converted from the closed state to the open state, second rope 36 is pulled to drive triangular rail passing plate 31 to rotate until the docking surface of triangular rail passing plate 31 presses second docking mechanism 4, and until the docking surface of triangular rail passing plate 31 is parallel to X axis.
[0041] As Figure 2As shown, the triangular rail passing plate 31 in the embodiment is provided with a first threading hole 33 and a second threading hole 34. The first threading hole 33 is formed on the top corner opposite to the abutting face of the triangular rail passing plate 31, and the first rope 35 is connected with the triangular rail passing plate 31 through the first threading hole 33; the second threading hole 34 is formed on the edge of the abutting face of the triangular rail passing plate 31, and is away from the rotating angle of the triangular rail passing plate 31, and the second rope 36 is connected with the triangular rail passing plate 31 through the second threading hole 34.
[0042] In order to ensure that the triangular rail passing plate 31 and the limiting rod 32 will not excessively rotate during use, the first abutting mechanism 3 in the embodiment one further comprises an upper limiting boss 37 and a lower limiting block 38 provided on the first rail 1 for limiting the limiting rod 32, when the first rail 1 and the second rail 2 are in the open state, the limiting rod 32 is in the horizontal position and contacts with the upper limiting boss 37, when the first rail 1 and the second rail 2 are in the closed state, the limiting rod 32 is in the vertical position and contacts with the lower limiting block 38. It should be understood that when the first rail 1 and the second rail 2 are in the closed state, the limiting rod 32 plays a role of stopping the hoist.
[0043] As shown in Figure 4 and Figure 5 As shown, the second abutting mechanism 4 in the embodiment one comprises a stop plate 42 installed on the second rail 2 through a rail connecting circular shaft assembly 41, an inclined plate 43 provided on the upper edge of the stop plate 42, and a reset block 44 provided on the second rail 2 for preventing the stop plate 42 from excessively rotating, when the inclined plate 43 is separated from the triangular rail passing plate 31, the rail connecting circular shaft assembly 41 drives the stop plate 42 to reset. The rail connecting circular shaft assembly 41 in the embodiment comprises a rotating shaft penetrating through the second rail 2, a reset spring provided on the rotating shaft, and a nut for fixing the stop plate 42 on one end of the rotating shaft. Those skilled in the art should be able to install the stop plate 42 and the rail connecting circular shaft assembly 41 according to the present specification and prior art, and the specific installation process of the stop plate 42 and the rail connecting circular shaft assembly 41 will not be described in detail here. It should be noted that when the first rail 1 and the second rail 2 are in the closed state, the stop plate 42 also plays a role of stopping the hoist.
[0044] The inclined plate 43 and the stop plate 42 in the embodiment one are integrally formed, and the inclined plate 43 is an arc-shaped plate inclined to the first rail 1. The inclined plate 43 and the stop plate 42 are designed in an integrated manner to ensure the bearing capacity of the inclined plate 43, and the inclined plate 43 is designed as an arc-shaped plate inclined to the first rail 1 to avoid the problem that the triangular rail passing plate 31 is stuck with the inclined plate 43 during pulling the second rope 36, and to ensure the smooth cooperation between the triangular rail passing plate 31 and the inclined plate 43.
[0045] Embodiment two
[0046] AsFigure 9 As shown, based on the content of the above embodiment one, the main difference is that in the second embodiment, the inclined plate 43 is a straight plate inclined to the first track 1, and the abutting surface of the triangular track passing plate 31 is provided with an arc-shaped positioning sliding groove 310 matched with the straight plate. The setting of the house type positioning sliding hole also avoids the problem that the triangular track passing plate 31 is stuck with the inclined plate 43 during the pulling of the second rope 36.
[0047] Referring to Figure 6 As an embodiment, the track passing device in the first embodiment or the second embodiment can further be provided with a threading pad plate 5 on the first guide rail. In specific use, one end of the first rope 35 is fixedly arranged in the first threading hole 33, and the other end is hung downward through the threading pad plate 5. The threading pad plate 5 is provided with a threading hole for threading out the first rope 35. The use of the threading pad plate 5 ensures that the first rope 35 can smoothly pull the triangular track passing plate to rotate, avoiding the sticking phenomenon caused by direct pulling.
[0048] As shown in Figure 7 and Figure 8 As an embodiment, the track passing device in the first embodiment or the second embodiment is provided with a horizontal positioning plate 6 arranged on the upper surface edge of the second track 2 and used to position the first track 1 in the Y-axis direction. The horizontal positioning plate 6 is arranged in a gap with the inclined plate 43 in the Y-axis direction.
[0049] During the actual abutting of the first track 1 and the second track 2, it is necessary to ensure that the first track 1 and the second track 2 are flush in the X-axis direction and the Y-axis direction. Otherwise, the gourd is prone to derailment. The first track 1 and the second track 2 are aligned in the X-axis direction by detecting their own height. In the present embodiment, the alignment in the Y-axis direction is achieved by the horizontal positioning plate 6 fixedly arranged on the second track 2. Referring to Figure 6 When the first track 1 and the second track 2 are not aligned in the Y-axis direction, the abutting surface of the triangular track passing plate is pressed on the horizontal positioning plate 6, and the inclined plate 43 cannot receive the pressure of the triangular track passing plate, so that the first track passing mechanism and the second track passing mechanism cannot complete the abutting. Thus, the problem of derailment caused by the movement of the gourd passing through the track due to the misalignment of the first track 1 and the second track 2 in the Y-axis direction is avoided. The present method is simple in structure and also ensures high reliability.
[0050] It should be understood that the manual hoist of the manual track passing device in the first embodiment and the second embodiment should also fall within the protection scope of the present utility model. The specific embodiments described above are only used to explain the present utility model and are not used to limit the present utility model. The obvious changes or variations derived from the spirit of the present utility model still fall within the protection scope of the present utility model.
