Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional parking garages, and in particular to a wire rope traction three-dimensional parking garage lifting system. Background Art

[0002] At present, the growth rate of automobiles is increasing year by year, especially in cities, which has led to more serious environmental pollution, traffic congestion, parking difficulties and other problems. For this reason, the country has implemented energy-saving and emission reduction policies, and many cities have also issued traffic restriction policies. The introduction of relevant policies has alleviated environmental pollution and traffic congestion, but the problem of "parking difficulties" still bothers everyone.

[0003] In today's fast-developing world, multi-story parking garages have become well known to everyone, especially multi-story parking garages with small footprints and large storage capacity, which have become one of the focuses of our lives. Various manufacturing companies are also gradually building super-high-rise multi-story parking garages, but super-high-rise multi-story parking garages have very high requirements for the lifting system.

[0004] The existing lifting system of super high-rise multi-story parking garages usually adopts chain transmission, but the chain transmission is prone to the phenomenon of chain and sprocket separation during high-speed transmission, and the noise is large when running at high speed, and the transmission stability is poor. Summary of the invention

[0005] In order to solve the technical problems that the parking system of the existing super-high-rise multi-story parking garage is prone to chain and sprocket separation during high-speed transmission, produces loud noise during high-speed operation, and has poor transmission stability, the present invention provides a wire rope traction multi-story parking garage lifting system.

[0006] The technical solution of the present invention is:

[0007] The utility model discloses a steel wire rope traction three-dimensional parking garage lifting system, which is special in that it comprises a frame, a power transmission system and a combined wheel system.

[0008] The power transmission system is arranged on the frame, and the combined gear train is in two groups and is respectively located on both sides of the power transmission system. The power transmission system includes a reduction motor and a main shaft; the reduction motor is a dual-output shaft reduction motor. There are two main shafts, which are respectively connected to the two output shafts of the reduction motor.

[0010] The traction wheel, the first supporting pulley, the second supporting pulley, the third supporting pulley and the guide wheel system are all arranged on the frame.

[0011] The first supporting pulley and the second supporting pulley are arranged in an up-and-down staggered manner, and the third supporting pulley and the second supporting pulley are arranged at the same height.

[0012] The traction wheel, the first supporting pulley and the second supporting pulley are all double-groove pulleys.

[0013] The guide wheel train comprises a first guide wheel train and a second guide wheel train; the first guide wheel train and the second guide wheel train are arranged in an up-down staggered manner.

[0014] The steel wire rope includes a first steel wire rope and a second steel wire rope.

[0015] One end of the first steel wire rope is used to connect the elevator, and the other end is passed around the upper part of the second support pulley, then passed through the upper part of the traction wheel to the lower part of the first support pulley, and finally passed around the first guide wheel system to connect the counterweight mechanism.

[0016] One end of the second steel wire rope is used to connect the elevator, and the other end is passed around the upper part of the third support pulley, passes through the upper part of the second support pulley, and then passes through the upper part of the traction wheel to the lower part of the first support pulley, and finally passes around the second guide wheel system to connect the counterweight mechanism.

[0018] Furthermore, in order to save installation space, the first guide wheel system includes a guide wheel bracket, a horizontal guide wheel and a vertical guide wheel fixed on the guide wheel bracket; the horizontal guide wheel and the vertical guide wheel are vertically arranged.

[0019] Furthermore, to make the structure more compact, a first seat bearing is arranged at one end of the main shaft, and the other end is connected to the traction wheel through a double support bearing; the first seat bearing and the double support bearing are both fixed on the active end frame.

[0020] Furthermore, the output shaft of the reduction motor is connected to the main shaft via a coupling.

[0021] Furthermore, in order to transmit a larger torque, reduce the requirement for the coaxiality between the output shaft of the reduction motor and the main shaft during installation, and reduce the processing cost, the coupling is a gear coupling.

[0022] Furthermore, in order to facilitate processing, the first supporting pulley and the second supporting pulley have the same size and structure.

[0023] Furthermore, the first supporting pulley, the second supporting pulley and the third supporting pulley are all fixed on the frame through a pulley shaft and a bearing seat with a seat.

[0030] 3. The coupling in the present invention is a gear coupling, which has a small size but transmits a large torque. At the same time, it has a low requirement for the coaxiality between the output shaft of the reducer and the main shaft, thereby reducing the processing cost.

[0031] 4. The first guide wheel system in the present invention includes a guide wheel bracket, a flat guide wheel and a vertical guide wheel fixed on the guide wheel bracket, which saves installation space.

[0032] 5. In the present invention, a first seat bearing is arranged at one end of the main shaft, and the other end is connected to the traction wheel through a double support bearing, which reduces the number of bearings used and makes the structure more compact.
