Description

f

The invention relates to trackless vehicles on earth vehicles, in particular, manually operated vehicles, namely hand trolleys equipped with lifting devices, and can be used in conditions of a motor vehicle having gas vehicles for replacing and transporting gas vehicles. cylinders.

The aim of the invention is to make it easier to replace and transport gas cylinders.

FIG. 1 shows a side view trolley; (the position of the cylinder at the time of removal from the frame of the car and on the support); in fig. 2 shows section A-A in FIG. one.

The trolley for replacing and transporting gas cylinders comprises a frame 1 mounted on three wheels 2, one of which is swiveling, self-adjusting.

Two vertical stands 3; they perform functions of guides for moving, lifting the carriage 4. The latter is equipped with four rollers 5 and a fork 6, which is rigidly connected to the frame of the carriage. The frame 1 is provided with transverse horizontal guides 7, in which an additional carriage 8 is installed, on which stands 3 are fixed. Carriage 4 is connected via cable 9 to a drum of a manual worm gear 10, fixed on racks 3. The additional carriage 8 has four rollers 11, with the help of which it moves along the guides 7, which are part of the metal structure of frame 1. On the frame 1, L-shaped supports 12 are installed for laying gas cylinders. To move the trolley, a handle 13 is used, rigidly mounted on the frame. To prevent spontaneous displacement

Under the frame during the movement of the cart there is a spring stopper 14.

Cylinders 15 are replaced in the following way.

The cart is being rolled up to the car from the side where gas cylinders 15 are on the frame 16 of the car, freed from the attachment by this time. Using a hand winch 10, a cable 9, move the lifting carriage 4 up to the level at which the fork 6 touches the cylinder 15 removed from the vehicle. Using the handle 13, the trolley is fed forward - until the cylinder 15 is fully seized by the fork capture 6. With the help of the winch W and the cable 9, the carriage 4 is slightly raised so that the cylinder 15 is lying on the trunk 6. The trolley is retracted under the car. With the help of the winch 0 we lower the carriage 4 with the balloon 15 down. Since the clearance between the two fork arms is greater than the width of the support part of the L-shaped support 12, the cylinder 15 will remain on the support 12, and the carriage 4 with the fork 6 will lower along the guide posts 3 to the lower end position. The additional carriage 8 is moved along the nanometer 7 to the side of the support on which the balloon to be replaced lies. After installing fork fork 6 under the balloon 15 by means of the winch 10 and the cable 9, the carriage 4 with the fork 6 moves upwards. The cylinder lying on support 2 is lifted by the fork 6. The cylinder is mounted on the frame of the car in the reverse order described when removing the cylinder from the car.

Attaching an additional carriage 8 on the trolley allows lateral movement of the forks 6 relative to the L-shaped supports.
