[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving on at least two rigid tracks perpendicular to the horizontal plane or at an angle of inclination less than 15° to the vertical. The car consists of a car frame and a car body. The car frame is the load-bearing structure of the car, and it must have sufficient strength to meet the safety requirements of the elevator. There are many types of elevators on the market, resulting in a wide variety of elevator car frames.
[0003] Because heavy-duty freight elevators require forklifts to load and unload goods, multiple guide rails are needed, but multiple guide rails will increase the obstruction during the operation of the elevator car.
[0004] To address this issue, a heavy-duty high-speed freight elevator car frame was designed to overcome the aforementioned problems. Summary of the Invention
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a top-mounted car top wheel device that is simple and reasonable in structure, easy to install, stable in operation, has good shock absorption effect, and is safe and reliable.
[0006] This utility model is achieved through the following technical solution: a heavy-duty high-speed freight elevator frame, comprising a freight elevator frame, the freight elevator frame comprising two identical main frames, each set of the main frames consisting of two upper beams, two straight beams, one support beam, and two lower beams. A horizontally arranged upper beam is installed at the top position between two adjacent straight beams, and both ends of the upper beam are connected to the top of the two adjacent straight beams by bolts. Below the upper beams, near the top position between two adjacent straight beams, a horizontally arranged support beam is installed, and both ends of the support beam are connected to the sides of the two adjacent straight beams by bolts. A horizontally arranged lower beam is installed near the bottom position between two adjacent straight beams. The four upper beams, four straight beams, four lower beams, and four support beams are spliced together to form a square frame structure. A horizontally arranged car bottom platform is fixedly installed directly above the four lower beams, and a car top wheel assembly is fixed directly below the two oppositely arranged support beams.
[0007] Preferably, the car top wheel assembly consists of a car top wheel beam, a car top wheel seat, and a car top wheel. The two ends of the car top wheel beam are respectively fixed to the middle position directly below two oppositely arranged support beams. A car top wheel seat is fixedly installed at each end of the car top wheel beam, and a car top wheel is installed on each car top wheel seat.
[0008] Preferably, each of the straight beams is fixedly installed with a lug near the middle position, and multiple horizontally arranged diagonal tie beams are fixed at the bottom of the car platform. The lug is connected to one end of the diagonal tie beam, and the other end of the diagonal tie beam is connected to the end of the diagonal tie beam by bolts. The arrangement of multiple diagonal tie beams is used to improve the support of the straight beams for the bottom of the car platform.
[0009] Preferably, the number of the diagonal tie beams is four, with two beams located at the bottom ends of the car platform and the other two beams located at the middle of the bottom of the car platform, with a gap between them.
[0010] Preferably, each straight beam has two symmetrical lugs on its inner and outer sides. The inner lug is connected to the end of one of the diagonal tie beams in the middle of the car bottom platform via a diagonal tie rod, and the outer lug is connected to the end of the diagonal tie beam at the end of the car bottom platform via a diagonal tie rod. The two diagonal tie rods are arranged in a figure-eight shape to ensure the straight beam supports the bottom of the car bottom platform.
