Problems solved by technology

The direction of the pressing force is inclined, which also offsets a part of the frictional driving force, resulting in a reduction in driving efficiency, which is what frictional driving does not want to see.
[0012] 3) Some products, such as excavators, are gradually developing into large-scale excavators, with a maximum weight of more than 40 tons. The maximum weight that the existing bottom conveyor line can carry is only 4 tons, which is far from enough to meet heavy-duty friction transportation. Require

Embodiment 1

[0049] As shown in the figure, a heavy-duty friction drive device of more than five tons includes a C-shaped fixed plate 1. The C-shaped fixed plate 1 includes a first jaw plate 1.1 and a second jaw plate 1.2 that are integrated with a bottom plate 1.3 and are oppositely arranged. The bottom plate 1.3 The lower surface is provided with a fixed seat 1.4, and the fixed seat 1.4 has a horizontal reference plane Л.

[0050] The first pivot 10 is rotatably fixed at a fixed position point P on the horizontal axis X 0 , the first pivot 10 is rotatably fixed on the first driving friction wheel mechanism 7 , and the first driving friction wheel mechanism 7 is a wheel supporting mechanism 40 . The wheel support mechanism 40 includes a support seat 41, the support seat 41 is provided with a positioning protrusion 43 and a U-shaped wall 44, the U-shaped wall 44 is provided with a shaft fixing hole 42, and a tapered roller bearing 45 is arranged in the shaft fixing hole 42. The first pivo...

Embodiment 2

[0065] Considering that the pressing force of the C-shaped fixed plate 1 reaches F 压 When the locking angle α between the main body axis 57 and the horizontal axis is 2°~5°, in order to adjust the locking angle α conveniently, the locking pier 12 is integrally arranged on the second jaw plate 1.2 instead of the locking pier 12 being slidably arranged on the second jaw plate. In the sliding hole of the plate 1.2, the adjusting screw 9 is rotatably connected to the locking pier 7, and the rotating adjusting screw 9 can drive the locking pier 12 to extend or retract the sliding hole for a certain distance: adjust the locking pier 12 to extend or retract the sliding hole distance until the pressing force reaches the required driving pressure F 压 The locking angle α between the main body axis 57 and the horizontal axis is 0°.

[0066] Other structures are the same as in Embodiment 1.

Abstract

The invention discloses a five or higher-tonnage heavy load friction driving device. The device comprises a C-shaped fixing plate (1), wherein the C-shaped fixing plate (1) comprises a first jaw plate(1.1), a second jaw plate (1.2) and a sliding rail (2); the first jaw plate (1.1) is fixedly provided with a first driving friction wheel mechanism (7), and the second jaw plate (1.2) is fixedly connected with a second driving friction wheel mechanism (8) through an opening and closing sliding mechanism (20); the opening and closing sliding mechanism (20) comprises a connecting rod bending and stretching mechanism (30) and a bending and stretching driving mechanism (50), wherein the connecting rod bending and stretching mechanism (30) is fixedly connected with the second driving friction wheel mechanism (8), and the bending and stretching driving mechanism (50) is connected between the second jaw plate (1.2) and the connecting rod bending and stretching mechanism (30) in a stretchable mode; and the opening and closing sliding mechanism (20) drives the second driving friction wheel mechanism (8) to slide between an abutting position and a retracting position. According to the five or higher-tonnage heavy load friction driving device, pressing force plays a role and is locked through the bending and stretching driving mechanism (50), and pressing force can be adjusted and can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of friction conveying systems, in particular to a heavy-duty friction drive device of more than five tons and a pressing force control method thereof. Background technique [0002] The car interior assembly skateboard conveyor line is mainly used for the ground transportation of the sprayed car body in the assembly workshop. The car body is placed on a 3m×6m large skateboard, and the operator assembles the car interior parts to the car body. The operator and the body move forward on the same slide, which greatly reduces the difficulty of operation. For the interior skateboard conveyor line, the main drive mechanism drives the skateboard along the conveying track by the friction generated by squeezing the skateboard. The total length of the interior skateboard conveying line is generally more than 150m, and it can carry more than 30 vehicles. However, using the friction conveying technology, it is only neces...
