[0001] The invention belongs to the field of installation platforms, and in particular relates to a five-degree-of-freedom equipment installation platform. Background Art

[0002] With the rapid development of my country's economy, the demand for urban rail vehicles has continued to increase, which has put forward high-quality and high-efficiency requirements for the production and maintenance of urban rail vehicles. The installation quality and efficiency of large equipment under and on urban rail vehicles directly affect the production and maintenance of urban rail vehicles.

[0003] At present, the installation of large equipment under and on urban rail vehicles is basically done by a mobile lifting trolley. During the installation process, it is difficult to align the installation holes of the equipment. In addition, due to the uneven ground, the equipment and the vehicle body are installed at an angle, which makes the installation process time-consuming and labor-intensive. Especially when the vehicle is under repair, the installation process of the equipment is different from that of a new vehicle. The pipeline does not need to be replaced during repair. During the installation process, the equipment is required to be in a freely adjustable state to ensure that the pipeline interface on the equipment can be connected to the original pipeline. Therefore, the current mobile lifting vehicle cannot meet the installation requirements of large equipment. Summary of the invention

[0009] Further optimized, the lead screw is a left-right trapezoidal thread lead screw.

[0010] Further optimized, the upper part of the connecting block is hinged to the connecting seat through a hinge pin.

[0011] Further optimization, the left-handed connecting nut and the right-handed connecting nut are nuts with a square middle, coaxially symmetrical pins are processed on both sides of the square nut, and the pins at both ends are respectively punched with threaded holes, and the lead screw is connected to the left-handed connecting nut and the right-handed connecting nut.

[0016] The present invention will be further described below in conjunction with the accompanying drawings:

[0017] like Figure 1 The five-degree-of-freedom equipment installation platform of the present invention includes three layers of adjustment mechanisms, which are, from bottom to top, an X-direction adjustment mechanism 1, a Y-direction adjustment mechanism 2, and a composite adjustment mechanism 3. The X-direction adjustment mechanism 1 and the Y-direction adjustment mechanism 2 have similar structures but different directions, and both are guide rail and sliding platform structures. By rotating the hand wheel, the equipment installation platform of the present invention can move horizontally in the X and Y directions.

[0018] like Figure 1 The composite adjustment mechanism 3 on the upper part of the equipment installation platform provides adjustment in three degrees of freedom along the Z-axis direction, rotation around the X-axis and rotation around the Y-axis, and includes an installation platform plate 15 and four support mechanisms 4 located at the four corners of the installation platform plate 15. The installation platform plate 15 is fixed on the upper part of the support mechanism 4.

[0019] like Figure 2Each supporting mechanism 4 includes a supporting connecting base 5, two limit blocks 6, eight connecting arms 7, a left and right trapezoidal thread screw 8, a right-handed connecting nut 9, a connecting block 10, a connecting seat 11, a left-handed connecting nut 12, a hand wheel 13, and three hinge pins 14.

[0020] The support connection base 5 at the bottom of the support mechanism 4 is fixedly connected to the plane of the Y-direction adjustment mechanism 2. A limit block 6 is fixedly installed on the upper part of the support connection base 5, which mainly plays a limit role to prevent the support mechanism 4 from failing. A connecting arm 7 is installed on the upper part of the limit block 6. Four pairs of connecting arms 7 are respectively connected to form two rhombus-shaped connecting arm groups. A connecting block 10 is installed on the top of the connecting arm group. A connecting seat 11 is connected above the connecting block 10. A lead screw 8 is inserted between the two connecting arm groups, and a hand wheel 13 is installed at the end of the lead screw. The rhombus lower end vertices of the two rhombus-shaped connecting arm groups are hinged to the limit block 6 through a hinge pin 14, and the rhombus upper end vertices are hinged to the connecting block 10 through a hinge pin 14. The upper part of the connecting block 10 is hinged to the connecting seat 11 through a hinge pin 14, so that the connecting seat 11 can rotate freely in two directions relative to the prismatic structure. The left end vertex of the rhombus is hinged by a left-handed connection nut 12, and the right end vertex of the rhombus is hinged by a right-handed connection nut 9. The left-handed connection nut 12 and the right-handed connection nut 9 are nuts with a square center. Coaxially symmetrical pins are processed on both sides of the square nut. The pins at both ends are respectively punched with threaded holes. The lead screw 8 is a left-right trapezoidal threaded lead screw with a self-locking function. The lead screw 8 is connected to the left-handed connection nut 12 and the right-handed connection nut 9.

[0021] When in use, place the device to be installed on the five-degree-of-freedom device installation platform of the present invention, and hoist the device installation platform as a whole to a position near the device to be installed. First, adjust the X-direction adjustment mechanism 1 of the first layer, and rotate the hand wheel to make the first layer platform move along the X-direction guide rail, so that the device as a whole moves horizontally in the X direction to a suitable position; then adjust the Y-direction adjustment mechanism 2 of the second layer, and rotate the hand wheel to make the second layer platform move along the Y-direction guide rail, so that the device as a whole moves horizontally in the Y direction to a suitable position; then adjust the Z-direction position, and rotate the hand wheels 13 of the four support mechanisms 4 at the same time to make the platform plate rise and fall vertically. By rotating the hand wheel 13, the lead screw 8 is driven to rotate, so that the left-handed connecting nut 12 and the right-handed connecting nut 9 move relative to each other, so that the top of the rhombus connecting arm group structure rises or falls quickly to a suitable position, and the trapezoidal thread structure of the lead screw 8 has a self-locking function, so that the 3-DOF composite support mechanism can adjust the height arbitrarily in the vertical direction and lock it in the adjusted position without displacement; finally, according to the needs of the equipment installation position, the rotation freedom around the X axis and around the Y axis is adjusted, and the hand wheels 13 of the two support mechanisms 4 on one side of the installation platform plate 15 are rotated at the same time, so that the installation platform plate 15 is adjusted along the opposite side for angle flipping. When the hand wheels 13 of the two support mechanisms 4 on one side of the X direction of the installation platform plate 15 are rotated at the same time, the installation platform plate 15 is adjusted along the opposite side for angle flipping in the X direction; similarly, when the hand wheels 13 of the two support mechanisms 4 on one side of the Y direction of the installation platform plate 15 are rotated at the same time, the installation platform plate 15 is adjusted along the opposite side for angle flipping in the Y direction until the equipment installation platform of the present invention is adjusted to the most suitable position.

[0022] The equipment installation platform of the present invention can also be fixed on a mobile lifting trolley, first moved to a position near the equipment to be installed by the trolley, and then the five-degree-of-freedom position is accurately adjusted.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
