Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment, in particular to an installation base for electromechanical equipment in subways. Background Art

[0002] Electromechanical equipment generally refers to machinery, electrical appliances and electrical automation equipment. With the continuous improvement of people's living standards, people have more and more demands for electromechanical equipment in their daily lives. It has become an indispensable electromechanical product in people's lives. Generally, electromechanical equipment for subways is relatively expensive. Therefore, it is not suitable to install electromechanical equipment directly on the ground. Generally, a mounting base is set on the ground and the electromechanical equipment is placed on the mounting base.

[0003] For example, a base for rapid installation of metro electromechanical equipment disclosed in a Chinese patent document (publication number: CN217302163U) is disclosed. Although this patent places the electromechanical equipment between the first baffle and the second baffle on the support seat, and pushes the second baffle to slide toward the first baffle, when the first baffle moves toward the second baffle, the two limit rods will gradually pass through the U-shaped mounting frame. After the first baffle and the second baffle clamp the electromechanical equipment, the threaded rod is rotated to make the fixed column on the threaded rod gradually approach the arc groove corresponding to the position of the U-shaped mounting frame until it is completely close to the first baffle. At this time, the first baffle can be installed. The positions of the baffle and the second baffle are fixed to prevent the electromechanical device from shaking during movement and causing damage to the internal parts of the equipment. However, when the electromechanical device is clamped and fixed, the first baffle is in a fixed state, and the electromechanical device is fixed only by moving the second baffle in coordination with the first baffle. This results in the electromechanical device not being located at the center above the support base after being fixed, which makes the support base less stable during movement and easily tipped over by external forces. Moreover, only the two sides of the electromechanical device are fixed, and the other two sides are still easily shaken by external forces, resulting in poor stability. Utility Model Content

DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

[0020] Specific implementation method 1: See Figure 1-Figure 4 The present embodiment is described in detail. The installation base for metro electromechanical equipment described in the present embodiment specifically includes a support base 1, a driving mechanism and a clamping and positioning device. The support base 1 is provided with a driving mechanism inside, and a clamping and positioning device is provided on the support base 1. The driving mechanism and the clamping and positioning device are connected; the clamping and positioning device includes two first fixed plates 7 and two positioning plates 72. The first fixed plate 7 is connected with the driving mechanism, and two vertical movable grooves 71 are symmetrically provided on the first fixed plate 7; the two positioning plates 72 are symmetrically arranged on the support base 1; one end of the positioning plate 72 is inserted into the movable groove 71 of one fixed plate 7, and the other end is inserted into the movable groove 71 of the other fixed plate 7. The two first fixed plates 7 and the two positioning plates 72 form a rectangular structure. The positioning plate 72 improves the stability of the first fixed plate 7 when it moves through the movable groove 71. The two positioning plates 72 are symmetrically distributed with the upper surface axis of the support base 1 as the symmetry center.

[0021] The positioning plate 72 is also provided with a screw 74, a driving turntable 75, a threaded sleeve 76, a second fixed plate 77 and two guide rods 78. The front of the second fixed plate 77 is fixedly connected with symmetrically distributed guide rods 78, which guide the movement of the second fixed plate 77. One end of the two guide rods 78 penetrates and extends to one side surface of the positioning plate 72. The positioning plate 72 is provided with a screw 74 through a bearing. One end of the screw 74 is provided with a driving turntable 75, and the other end is threadedly connected with the threaded sleeve 76. The other end of the threaded sleeve 76 is connected with the second fixed plate 77. The screw 74 is driven to rotate by rotating the driving turntable 75, and the screw 74 and the threaded sleeve 76 are threadedly engaged to drive the threaded sleeve 76 to move. The clockwise rotation of the screw 74 drives the threaded sleeve 76 to extend, and the counterclockwise rotation drives it to retract.

[0022] The positioning plate 72 is set on the support base 1 through two fixing rods 73; the lower surface of the positioning plate 72 is fixedly connected with symmetrically distributed fixing rods 73, and the fixing rods 73 play a role in fixing and supporting the positioning plate 72. One end of each of the multiple fixing rods 73 is fixedly connected to the upper surface of the support base 1.

[0023] The driving mechanism includes a bidirectional screw 3, a worm wheel 4, two threaded blocks 5, two connecting blocks 6 and a driving device. The inner walls on both sides of the support base 1 are equipped with bidirectional screws 3 through bearings. The bidirectional screw 3 is provided with two sections of threaded structures with opposite rotation directions, and a worm wheel 4 is provided at the center of the bidirectional screw 3; a threaded block 5 is provided on the threaded structure to cooperate, and a connecting block 6 is provided at the upper end of the threaded block 5; two travel grooves 2 are provided on the support base 1, and the upper end of the connecting block 6 passes through the travel groove 2 and is connected to the first fixed plate 7; the worm wheel 4 is connected to the driving device. The clockwise rotation of the bidirectional screw 3 drives the two threaded blocks 5 and the connecting block 6 to move relative to each other, while the counterclockwise rotation causes them to move in opposite directions.

[0024] The driving device includes a servo motor 79 and a worm 710. The output end of the servo motor 79 is connected to the worm 710 through a coupling, and the worm 710 is meshed with the worm wheel 4.

[0025] The specific working process of the installation base for subway electromechanical equipment described in the utility model is explained as follows:

[0026] The electromechanical device is placed at the center above the support base 1, and the servo motor 79 is started. The servo motor 79 drives the worm 710 to rotate clockwise. The rotation of the worm 710 drives the bidirectional screw 3 to rotate through the meshing worm wheel 4. The rotation of the bidirectional screw 3 causes the two threaded blocks 5 to move relative to each other through the limit of the stroke groove 2. The movement of the threaded block 5 drives the first fixed plate 7 to move through the connecting block 6. The movement of the first fixed plate 7 is coordinated with the moving groove 71 to move along the positioning plate 72, thereby automatically clamping and positioning the two sides of the electromechanical device.

[0027] The screw rod 74 is driven to rotate clockwise by driving the turntable 75. The rotation of the screw rod 74 is positioned and rotated through the cooperation of the bearing, and the guide limit of the guide rod 78 causes the threaded sleeve 76 to drive the second fixed plate 77 to extend and move. The movement of the second fixed plate 77 clamps and positions the other two sides of the electromechanical equipment, thereby improving the stability of the installation of the electromechanical equipment.

[0028] To summarize the above implementation cases, the utility model described in the present invention is a kind of installation base for subway electromechanical equipment, which overcomes the problems of poor stability of the existing support base and poor equipment fixing effect. The electromechanical equipment is fixed from four directions by the first fixing plate 7 and the second fixing plate 77, which enhances the equipment fixing effect and realizes the fixing of the electromechanical equipment at the center of the support base. It not only improves the stability of the installation of the electromechanical equipment, but also facilitates the operation during installation and reduces the difficulty of installation.

[0029] The specific embodiments described above further describe the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific embodiment of the utility model and is not intended to limit the utility model.
