Description
Technical Field
The utility model relates to an elevator technical field, concretely relates to a track arrangement structure for platform ladder.
Background
The platform ladder is an elevator without a lift car, and the platform is driven by the traction of a traction machine to do reciprocating lifting motion along a fixed guide rail. The platform ladder is arranged in a preset shaft in a building, and a main guide rail (car guide rail) and an auxiliary guide rail (counterweight guide rail) are fixedly arranged in the shaft. The platform moves up and down along the car under the drive of the traction machine.
In the prior art, a counterweight guide rail is arranged in a car guide rail, and the counterweight guide rail is arranged in front of the car guide rail. The arrangement structure can increase the longitudinal size of the shaft, thereby increasing the space occupied by the platform ladder, namely increasing useless space and reducing space utilization rate.
SUMMERY OF THE UTILITY MODEL
The utility model discloses plan to provide a track arrangement structure for platform ladder can effectively reduce the space that the platform ladder occupy to improve space utilization.
Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides a track arrangement structure for platform ladder, includes to heavy guide rail, car guide and strut, two the interval sets up about the strut, to heavy guide rail about including the interval set up first to heavy guide rail and second to heavy guide rail, first car guide rail and the second car guide rail that the interval set up about car guide is including, first to heavy guide rail and second to heavily leading the rail setting between first car guide rail and second car guide rail, first to heavy guide rail, second to heavy guide rail, first car guide rail and second car guide rail all on same straight line, first to heavy guide rail and first car guide rail install relatively on left strut, the second to heavy guide rail and second car guide rail install relatively on the strut on right side.
Preferably, in the above aspect, the counterweight guide rail and the car guide rail both use T-shaped guide rails.
Preferably, the bracket is a bent part with a downward groove, the bracket is internally provided with a supporting reinforcing rib, and the left side surface and the right side surface of the bracket are respectively provided with two strip-shaped guide rail mounting holes at intervals in the front-back direction and in the transverse direction.
Preferably, guide rail gaskets are arranged between the support frame and the counterweight guide rail and between the support frame and the car guide rail and used for limiting the guide rail fixing bolt to deviate forwards or backwards along the guide rail mounting hole.
Preferably, the elevator shaft further comprises a support frame seat, the rear end of the support frame is fixedly welded on the support frame seat, and the support frame seat is fixedly installed on the inner wall of the shaft.
The utility model has the advantages that: to heavy guide rail and car guide rail setting on same straight line, make the structure of platform ladder compacter, compare with traditional arrangement mechanism, can effectively reduce the longitudinal dimension of well to reduce the space that the platform ladder occupy, and then improve space utilization.

Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
referring to fig. 1-4, a track layout structure for a platform ladder mainly comprises a counterweight guide rail, car guide rails and support frames 1, wherein the two support frames 1 are arranged at left and right intervals, the counterweight guide rail comprises a first counterweight guide rail 2 and a second counterweight guide rail 3 which are arranged at left and right intervals, the car guide rail comprises a first car guide rail 4 and a second car guide rail 5 which are arranged at left and right intervals, and the first counterweight guide rail 2 and the second counterweight guide rail 3 are arranged between the first car guide rail 4 and the second car guide rail.
First counterweight guide rail 2, second counterweight guide rail 3, first car guide rail 4 and second car guide rail 5 all are on same straight line, and first counterweight guide rail 2 and first car guide rail 4 are installed on left strut 1 relatively, and second counterweight guide rail 3 ann and second car guide rail 5 are installed on the strut 1 on right side relatively.
In order to facilitate the installation of the counterweight guide rail and the car guide rail, the counterweight guide rail and the car guide rail both adopt T-shaped guide rails.
In order to ensure the connection strength of the strut 1, the strut 1 adopts a bending piece with a downward groove, and a supporting reinforcing rib is arranged in the strut 1; in order to enable the support frame 1 to be suitable for guide rails with different sizes, two strip-shaped guide rail mounting holes are transversely arranged on the left side surface and the right side surface of the support frame 1 at intervals in the front-back direction.
Because the guide rail mounting hole adopts the bar hole, and the guide rail is T type guide rail simultaneously, for guaranteeing in the use, because receive vibrations, guide rail fixing bolt can not be along guide rail mounting hole forward or backward movement, be provided with guide rail gasket 6 between strut 1 and counterweight guide rail, strut 1 and car guide rail, and guide rail gasket 6 needs to be selected according to the size of guide rail and the distance between strut and the guide rail.
Because strut 1 is the piece of bending, for guaranteeing that strut 1 can fixed mounting on the inner wall of well, the fixed welding of rear end at strut 1 has a support seat 7, and support seat 7 passes through bolt fixed mounting on the well inner wall simultaneously.
