Further, driving motor and drive shaft install in the top of support post, the driven shaft is installed in the top of direction stand.

Further, the rails are arranged on two sides of the connecting frame in parallel.

Furthermore, a maintenance hanging bracket assembly is arranged on the driving platform frame.

Further, the maintenance hanger assembly includes escalators and guardrails installed at both ends of the driving platform frame and a hanger installed above the driving assembly.

The invention has the beneficial effects that: the elevator has the advantages that the elevator is simple in structure, high in space utilization rate and low in requirement on initial design planning, the original functions can be realized by changing the two original elevators into one elevator, motors, belts, counter weights and the like are reduced by half, and the cost is saved.

Detailed Description

The invention is further illustrated by the following examples and figures.

As shown in the figure: the double-rail elevator comprises a support upright 1, a guide upright 2, a sliding frame assembly 3 and a driving platform assembly 5. The carriage assembly 3 comprises a connecting frame 3.1, a carriage frame 3.2 arranged on the connecting frame 3.1 and two rails 3.3 connected by the connecting frame 3.1, and the carriage frame 3.2 is sleeved outside the guide upright post 2. The driving platform assembly 5 comprises a driving platform frame 5.1 and a driving assembly, the driving platform frame 5.1 is installed at the tops of the supporting upright posts 1 and the guide upright posts 2, and the driving assembly is installed on the driving platform frame 5.1 and used for driving the sliding frame assembly 3 to move up and down along the guide upright posts 2.

Specifically, drive assembly includes driving motor 5.2, drive shaft 5.3, driven shaft 5.4 and belt 5.5, driving motor 5.2 installs on drive platform frame 5.1, drive shaft 5.3 connects driving motor 5.2's pivot, driven shaft 5.4 is on drive platform frame 5.1 in a parallel with drive shaft 5.3, belt 5.5 winding is on drive shaft 5.3 and driven shaft 5.4, the one end of belt 5.5 is equipped with counterweight assembly 4, carriage frame 3.2 is connected to the other end of belt 5.5. Two driving shafts 5.3 are arranged on two sides of one end of the driving platform frame 5.1, the driving shafts 5.3 are arranged between the two driving motors 5.2, and the driving stability is high. In order to ensure the stability of the structure, the guide upright posts 2, the carriage frame 3.2 and the driven shafts 5.4 are correspondingly arranged in two groups, and the belt 5.5 is wound on the driving shaft 5.3 and one driven shaft 5.4; the driving motor 5.2 and the driving shaft 5.3 are arranged above the supporting upright post 1, and the driven shaft 5.4 is arranged above the guiding upright post 2. The rails 3.3 are arranged in parallel on both sides of the connecting frame 3.1. Be equipped with maintenance gallows subassembly 6 on drive platform frame 5.1, be convenient for maintain, maintenance gallows subassembly 6 can be including installing the gallows at the staircase and the guardrail at drive platform frame 5.1 both ends and installing in driving motor 5.2 and drive shaft 5.3 top.

The working process is as follows: a motor in the driving platform assembly drives the sliding frame assembly to lift through belt transmission; when in the air, the trolley with the body-in-white enters the track at one side on the sliding frame, and the trolley with no load on the track at the other side exits the lifter and enters the air for circular conveying; after the actions are finished, the motor drives the belt to drive the sliding frame to a low position, and the trolley with the white trolley body leaves the upper track of the sliding frame and is conveyed on the ground; and the empty trolley on the ground enters the other side track of the sliding frame of the elevator; after the actions are finished, the lifter is lifted to a high position in the air, and the actions above the lifter are reciprocated, so that the trolley is recycled in the white body conveying process.

The invention realizes the full load and no load lifting of the trolley through one lifter, can effectively save space, saves cost compared with two lifters, and reduces the workload of installation, maintenance, after sale and the like.
