Description

Technical Field

[0001] This utility model relates to the field of elevators, specifically to a platform elevator traction machine frame. Background Technology

[0002] A platform elevator is a type of elevator used for vertically transporting goods. It typically does not have an enclosed car, but instead provides an open or semi-open platform for loading and unloading large or heavy items. The platform elevator is the power source for the elevator, using steel cables or chains to raise or lower the car or platform. The traction machine frame is the structural framework of the elevator system used to install and support the traction machine. It usually includes support beams, connectors, and other fixing devices to secure the traction machine and withstand the forces generated during its operation.

[0003] Chinese Patent CN214087247U discloses a traction machine frame device for a platform ladder. The device includes a horizontally arranged traction machine frame with traction machine mounting holes. At least two upward-extending shaft mounting plates are vertically spaced at intervals on the rear side of the traction machine frame. Downward-extending guide rail mounting plates are located at both ends of the traction machine frame. A speed limiter bracket is positioned downwards near the right end of the traction machine frame, located to the right of the traction machine mounting holes. After installation, the speed limiter is positioned directly below the traction machine frame. The shaft mounting plates and guide rail mounting plates on the traction machine frame ensure that the rear end of the traction machine frame is mounted on the shaft and supported by the guide rails, resulting in a secure installation. The speed limiter bracket, positioned directly below the traction machine frame after installation, makes the entire structure more compact.

[0004] However, the above-mentioned solutions have the following shortcomings: the mounting hole positions of the traction machine are fixed, and only traction machines of specific types and sizes can be installed, which greatly limits their use and makes them less versatile. Utility Model Content

[0005] The purpose of this utility model is to address the problem in the background technology that only traction machines of specific types and sizes can be installed, resulting in great limitations in use and poor versatility, and to propose a platform elevator traction machine frame.

[0006] The technical solution of this utility model: a platform elevator traction machine frame, comprising:

[0007] The load-bearing plate connects to the shaft.

[0011] And mounting bolts, of which four are provided, two of which pass through the traction machine mounting hole, the first traction machine mounting hole and the first threaded hole, and the other two pass through the traction machine mounting hole, the second traction machine mounting hole and the second threaded hole.

[0012] Preferably, bottom reinforcing plates are vertically installed on both sides of the bottom of the load-bearing plate, two clearance grooves are provided on the load-bearing plate, two shaft mounting plates are provided at the bottom of the load-bearing plate, and multiple shaft mounting holes are provided on the shaft mounting plates.

[0013] Preferably, the bottom reinforcing plate has two strip grooves at the top, and the strip grooves form openings on both sides of the load-bearing plate. The U-shaped plate passes through the strip grooves, and a sealing plate is provided near the end of the strip grooves of the load-bearing plate.

[0014] Preferably, the bottom reinforcing plate and the load-bearing plate are integrated, and the sealing plate and the well mounting plate are installed after the U-shaped plate is installed into the strip groove.

[0015] Preferably, multiple slide rails are provided on the top of the load-bearing plate along the horizontal direction, and multiple slide grooves are provided on the bottom of the slide plate, with the slide rails and slide grooves cooperating.

[0016] Preferably, a first mating threaded hole is provided on the end face of the slide plate facing the fixed plate, and multiple second mating threaded holes are provided on the end face of the fixed plate facing the slide plate along the transverse direction. One of the second mating threaded holes is longitudinally opposite to the first mating threaded hole.
