The vehicle is lifted and the installation position of the load-bearing drive mechanism is above the interior of the carriage. The space is narrow and the working conditions are complex. There are interference factors such as cover plates, handrails, and seats, resulting in complex disassembly and assembly operations. Usually, multiple translational degrees of freedom and multiple rotational degrees of freedom are required. The structure of the load-bearing drive mechanism itself is complex and the internal components are movably connected. A fast, reliable and simple clamping device is particularly important.

[0004] Therefore, a fast clamping and auxiliary disassembly and assembly operation device with a simple structure and easy operation is needed for the disassembly, assembly, maintenance and repair site of the load-bearing drive mechanism. Content of the Utility Model

[0034] The technical solutions of the present utility model will be introduced in detail below in combination with the specific embodiments and the drawings in the specification.

[0035] As Figures 1 to 6As shown in the figure, the mechanism clamping device applicable to the door system of rail vehicles of the present utility model comprises the following components: a mechanism clamping platform 2, a mechanism positioning device 3, a first positioning device 31, a second positioning device 32, a positioning and limiting device 33, an adjusting shim 34, a clamping device 4, a base 41, a claw 42, a ratchet pawl 43, a tension spring 44, an unlocking handle 45, a folding operating rod 5, a fixed seat 51, a pin shaft 52, an operating rod 53, an operating rod clamping seat 54, and a handrail 6.

[0036] The above-mentioned mechanism clamping device applicable to the door system of rail vehicles can be used to clamp and carry a driving mechanism 1, such as Figure 7 As shown in the figure, the driving mechanism 1 carried includes a frame 11, a short guide post 12, a long guide post 13, and a door-carrying frame 14. Among them, the frame 11 and the short guide post 12 are fixedly connected, the long guide post 13 is slidably connected to the short guide post 12, the long guide post 13 can move along the axis direction of the short guide post 12, and the door-carrying frame 14 is rotatably connected to the long guide post 13 and can rotate around the axis of the long guide post 13 and move along the axis direction.

[0037] As Figure 1 shown in the figure, the lower part of the mechanism clamping platform 2 is connected to external equipment, and the mechanism positioning device 3 is installed on the upper surface of the mechanism clamping platform 2 for positioning the driving mechanism 1 carried. The clamping device 4 is installed on the upper surface of the mechanism clamping platform 2 for locking the driving mechanism 1 carried. A group or more of folding operating rods 5 are installed at the bottom of the mechanism clamping platform 2. In this embodiment, the number of folding operating rods 5 is set to two groups. A plurality of handrails 6 are fixedly arranged in front of and on both sides of the mechanism clamping platform 2. In this embodiment, two handrails 6 are arranged in front of the mechanism clamping platform 2, and one handrail 6 is installed on each side of the mechanism clamping platform 2. The driving mechanism 1 carried is clamped above the mechanism clamping platform 2 through the mechanism positioning device 3 and the clamping device 4. After the driving mechanism 1 carried is locked, the folding operating rod 5 is operated to be in an unfolded state, and then the mechanism clamping platform 2 is pushed, so that the mechanism clamping platform 2 together with the driving mechanism 1 carried rotates in any direction and moves in multiple directions.

[0038] As Figure 2 shown in the figure, the mechanism positioning device 3 includes a first positioning device 31, a second positioning device 32, a positioning and limiting device 33, and an adjusting shim 34. The number of the first positioning devices 31 is two groups, which are symmetrically arranged at both ends of the mechanism clamping platform 2. The number of the second positioning devices 32 is one group, which is located between the two groups of the first positioning devices 31 and is arranged closely against one side of the mechanism clamping platform 2. The first positioning device 31 and the second positioning device 32 jointly form a three-point constraint. The number of the positioning and limiting devices 33 is two groups, which are arranged at intervals closely against the other side of the mechanism clamping platform 2.

[0039] The first positioning device 31 includes two first fixing seats arranged at intervals. A V-shaped surface is provided on the top surface of each first fixing seat for accommodating the long guide post 13 of the load-bearing driving mechanism 1. The second positioning device 32 includes a second fixing seat. A V-shaped surface is provided on the top surface of the second fixing seat for accommodating the short guide post 12 of the load-bearing driving mechanism 1. A boss is provided on the positioning and limiting device 33, and the side surface of the boss contacts the door-carrying frame 14 of the load-bearing driving mechanism 1.

[0040] As Figure 2 and Figures 7 - 9 shown, there are two first positioning devices 31, symmetrically installed on both sides of the mechanism clamping platform 2, for mainly positioning the load-bearing driving mechanism 1 with respect to the long guide post 13; the second positioning device 32 performs secondary positioning on the load-bearing driving mechanism 1 with respect to the short guide post 12; there are two positioning and limiting devices 33, symmetrically installed along the central axis of the mechanism clamping platform 2, for limiting the door-carrying frame 14. The first positioning device 31 provides the main positioning function. The V-shaped surface restricts the movement of the load-bearing driving mechanism 1 along the direction of the short guide post 12, and at the same time restricts the rotation of the load-bearing driving mechanism 1 along the axis direction of the short guide post 12. The side surface of the positioning and limiting device 33 restricts the movement of the door-carrying frame 14 along the axis direction of the long guide post 13. The second positioning device 32 provides the secondary positioning function. The V-shaped surface restricts the movement of the short guide post 12 along the width direction of the load-bearing driving mechanism, and the side surface restricts the movement of the short guide post 12 along its own axis direction.

[0041] The first positioning device 31 and the second positioning device 32 jointly form a three-point constraint to realize the constraint on the rotation of the load-bearing driving mechanism around the axis direction of the long guide post 13. The positioning and limiting device 33 holds up the door-carrying frame 14, and the side surface restricts the movement of the door frame 14 along the axis of the long guide post 13.

[0042] As Figure 2 shown, an adjustable fixed connection is adopted between the first positioning device 31, the second positioning device 32, the positioning and limiting device 33 and the mechanism clamping platform 2. In this embodiment, adjustment shims 34 are provided between the first positioning device 31, the second positioning device 32, the positioning and limiting device 33 and the mechanism clamping platform 2, which can adapt to the clamping of load-bearing driving mechanisms 1 of different specifications and sizes.

[0043] As Figure 3As shown in the figure, the clamping device 4 mainly includes a base 41, a claw 42, a ratchet pawl 43, a tension spring 44, an unlocking handle 45, etc. The claw 42 and the ratchet pawl 43 are respectively rotatably connected to the base 41, and the tension spring 44 and the unlocking handle 45 are installed on the base 41. One end of the tension spring 44 is connected to the base 41, and the other end is connected to the ratchet pawl 43 for pulling the ratchet pawl 43 towards the claw 42 side. The unlocking handle 45 and the ratchet pawl 43 can rotate synchronously. The clamping device 4 is provided beside the first positioning device 31. When the long guide post 13 of the load-bearing driving mechanism 1 approaches the V-shaped surface of the first positioning device 31 downward, it first contacts the claw 42 and makes it rotate downward. Until the long guide post 13 contacts the V-shaped surface, the claw 42 is automatically locked under the action of the ratchet pawl 43 and the tension spring 44. When unlocking, operate the unlocking handle 45, and the claw 42 releases the restraint on the long guide post 13.

[0044] As Figures 4 - 6 shown, the folding operating rod 5 includes a fixed seat 51, a pin shaft 52, an operating rod 53 and an operating rod clamping seat 54. The fixed seat 51 and the operating rod clamping seat 54 are respectively fixedly connected to the mechanism clamping platform 2, and the fixed seat 51 and the operating rod clamping seat 54 are arranged at intervals. The front end of the operating rod 53 is rotatably connected to the fixed seat 51 through the pin shaft 52, and the operating rod clamping seat 54 is used to accommodate the operating rod 53. A moving groove 532 is opened at the front end 531 of the operating rod 53, and the middle section 533 is adjacent to the front end 531. A pin hole 511 for matching the middle section 533 of the operating rod 53 is opened in front of the fixed seat 51, and a notch 512 matching the contour of the front end 531 is opened on the side of the fixed seat 51. The pin hole 511 communicates with the notch 512. The operating rod clamping seat 54 is provided with a C-shaped notch 541 matching the middle section 533. The body of the operating rod clamping seat 54 has a certain elasticity, so that the middle section 533 of the operating rod 53 can enter and be held in the C-shaped notch under the action of an external force.

[0045] When the folding operating rod 5 is not in use, it is in a folded state. The front end 531 is located in the notch 512, and the middle section 533 is located in the C-shaped notch 541. At this time, the operating rod 53 is fixed.

[0046] When using the folding operating rod 5, make the middle section 533 disengage from the C-shaped notch 541 by an external force, pull the operating rod 53 to rotate around the pin shaft 52 to the front of the pin hole 511, and insert the middle section 533 into the pin hole 511 through the moving gap between the moving groove 532 and the pin shaft 52. At this time, the operating rod 53 is limited. The mechanism clamping platform 2 can be adjusted through the operating rod 53, so as to achieve the purpose of adjusting the load-bearing driving mechanism 1. The operating rod 53 facilitates operation while reducing the operating force. There are two folding operating rods 5, which are distributed on both sides of the mechanism clamping platform 2 and arranged vertically and staggered, making the structure more compact.

[0047] As Figure 1As shown in the figure, handrails 6 are provided in front of and on both sides of the mechanism clamping platform 2 and are fixedly connected to the mechanism clamping platform 2, facilitating the operator to adjust the posture of the load-bearing drive mechanism 1 at different positions and in different postures of the mechanism clamping platform 2 to better achieve the purpose of its auxiliary disassembly and assembly operation.
