the lifting platform is provided with a lifting platform frame which is a box-shaped structure consisting of a plurality of rod bodies and is provided with a guardrail door.
the bottom end of a connecting rod at the bottom of the scissor mechanism is hinged to the horizontal bottom plate.
The guide rail is upright channel steel, and the guide rail groove is C shape, and upright guide rail one end welding is on subway overhauls operation platform stand, and one end embedding guide rail groove's C inslot.
The utility model has the advantages of it is following:
1. The device adopts a scissor type lifting mechanism which can be extended and contracted, and occupies a small space; the structure is simple, the reliability is high, and the maintenance is easy; the clearance between each motion component is less, and the lift process can not take place to rock. Therefore, the scissor type lifting mechanism is used as a core component of the device, has the characteristics of small occupied space, high reliability, convenience in maintenance and the like, and is suitable for carrying out frequent tool and material transportation operation during vehicle maintenance.
2. In order to further improve the stability of the platform during lifting and ensure that the platform cannot be blocked during lifting due to uneven load distribution, a group of sliding guide rails are arranged on two sides of the scissor fork mechanism along the lifting vertical direction, and a group of rolling pulleys arranged on two sides of the platform are matched with a guide rail groove, so that the limitation on the movement of the platform in the transverse direction and the longitudinal direction is realized.
3. the installation position of the device is installed by combining with the gap of the upright post of the maintenance operation platform, and the device can be positioned at both ends of the maintenance operation platform or in the middle of the platform; the size of the lifting platform is determined by combining the gap of the upright post of the maintenance operation platform, the overall transverse size of the operation platform is ensured not to be changed after installation, and the relative position relation between the lifting platform and the vehicle body completely meets the related requirements of the equipment clearance of the railway locomotive.

Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The utility model relates to a set up instrument lift platform in subway overhauls operation platform, this lift platform sets up in railcar overhauls operation platform stand space within a definite time, including cutting fork mechanism 1 and its top horizontally lift platform 3, 3 sizes of lift platform should combine the stand space to consider, and the high 3.8m of platform lift ensures that the material can be transported to the subway train roof from ground. The scissor fork mechanism 1 is a lifting device and is composed of a plurality of groups of X-shaped crossed connecting rods, the upper layer connecting rods and the lower layer connecting rods are hinged through end parts, 2 hydraulic cylinders 2 are installed between the upper layer connecting rods and the lower layer connecting rods, the hydraulic cylinders 2 stretch to drive the scissor fork mechanism 1 to shrink integrally, the total lifting height is 3.8m, and the lifting platform 3 is moved up and down. The operation of the hydraulic cylinder 2 is realized by controlling the motor and the hydraulic pump, and the scissor mechanism 1 is controlled to generate vertical thrust and pull force to realize the lifting of the platform. The bottom end of a connecting rod at the bottom of the scissors mechanism 1 is hinged to the horizontal bottom plate 6, so that a stable foundation is provided for the extension and contraction of the scissors mechanism 1.
