Abstract
The utility model relates to a hanging rail trolly. The basic composing of the hanging rail trolly comprises a carriage, walking wheels, a damping roller, a motor, a belt wheel, and a driving belt, wherein, the numbers of the walking wheels on two sides of the vertical surface of a guide rail are respectively two and one. The hanging rail trolly efficiently overcomes harmful torque generated by different motion directions caused by four walking wheels, and the shocking and tail clamping problems of the hanging rail trolly are solved. The hanging rail trolly is steady to run, and is free to advance and retreat. The stable quality of taking a photograph and the accurate positioning of a camera are ensured.
Description
The utility model relates to a kind of improved camera mount that is used for video camera hanging rail device, belongs to video camera accessory technical field.
Take operative site and need use a kind of device that is referred to as the video camera hanging rail, the guide rail in the device is fixed on the ceiling, and Overhead rail cart is set on the guide rail, and video camera promptly is installed on the Overhead rail cart, the shooting of the mobile realization different angles by dolly.In No. 98202044.9 Chinese patents, the former design of the Overhead rail cart in the device is four road wheels of symmetric arrangement, finds in the use to produce shake or card rail phenomenon when arc track moves, and influences the accurate location of pickup quality and video camera.
The purpose of this utility model provides a kind of Overhead rail cart that can make video camera along arc-shaped guide rail easy motion and accurate location.
The purpose of this utility model is realized by following technical scheme:
A kind of Overhead rail cart comprises railway carriage 2, road wheel 8,15, damping roller 9, motor 5, belt pulley 3, driving belt 7, wherein in its basic comprising, the quantity of road wheel 8 is two, be installed on the outside of guide rail, the quantity of road wheel 15 is one, is installed on the inboard of guide rail.And be positioned at two road wheels 8 the axle 12 wheelbase centers extended line on.
Above-mentioned Overhead rail cart, the quantity of described damping roller are two pairs, and equilibrium is configured in the top of Overhead rail cart, each damping wheel 9 both sides that overlay respectively at the guide rail facade.
Above-mentioned Overhead rail cart, described damping roller 9 are installed in the groove 14 of fork arm 11 ends, and the shaft of fork arm 11 is with spring 13, also inserts in the sleeve 10 that is fixed on the dolly inwall.
Above-mentioned Overhead rail cart, the outer rim of described road wheel 8,15 is surrounded by rubber or plastic layer.
Overhead rail cart according to the utility model making, overcome harmful moment of torsion that the direction of motion difference of using four road wheels to cause is produced effectively, the shake and card rail problem of Overhead rail cart have been solved, make trolley travelling steady, free to advance or retreat, guaranteed pickup quality stable and Camera Positioning accurately.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a longitudinal sectional view of the present utility model;
Fig. 2 is a horizontal cross.
In the utility model, when Overhead rail cart when arc-shaped guide rail moves, the side that a road wheel is housed is positioned at the inboard of arc-shaped guide rail, there is a side of two road wheels to be positioned at the outside of arc-shaped guide rail, owing to reduced the number and the configuration triangular in shape of road wheel, the resistance of motion and harmful moment of torsion of Overhead rail cart have been reduced effectively, simultaneously because the damping rollers of two pairs cushioning effects are housed on the top of Overhead rail cart, further controlled the double swerve of Overhead rail cart effectively, make the Overhead rail cart can be steady, on the arc video camera hangs moving guide rail, move freely, thereby guaranteed pickup quality and video camera accurate location at random.
Damping roller 9 in the utility model adopts nylon, plastics or rubber to make, and high resilience can be played better damping absorption to vibrations.
