CS258214B1 - Body protection device on the vehicle - Google Patents

Abstract

The bodywork locking device on the vehicle is designed to lock the bodywork remotely from the driver's cabin. It is arranged on the vehicle frame perpendicular to the vehicle axis in the area of the front part of the bodywork and consists of teeth that are pivoted on the frame. The teeth are connected by arms to rods that are coupled to a rocker arm. The rocker arm is connected to an air cylinder via a lever.

Description

258214 2

BACKGROUND OF THE INVENTION The present invention relates to a superstructure securing device on a vehicle operated remotely from a cab.

The existing superstructures on the vehicle are secured by means of clamping screws, where the operator must manually lock the side of the vehicle. This solution is lengthy and requires the presence of operators outside the cab.

The above-mentioned drawbacks are eliminated by the superstructure securing device of the vehicle according to the invention, which is based on the vehicle frame perpendicular to the vehicle axis in the front and rear of the body and consists of cogs which are pivoted from both sides of the vehicle. The claws are the shoulders connected to the rods, which are connected to the axles by the rocker arm. The rocker arm is mounted on the shaft and fixedly coupled to the piston rod lever. Another feature is that in the Xav's arm there is an aperture through which the bolt is screwed to the vehicle frame, while the right arm is oriented toward the switches housed in the vehicle frame and the teeth have bevel surfaces formed at the top.

The safety device according to the invention is simple and allows fast locking and unlocking of the vehicle on the vehicle at the same time.

1 shows a front view of a vehicle with a superstructure and a securing device, and FIG. 2 is a schematic representation of a section along line A-A of FIG. 1.

On the platform of the vehicle 2 there is a superstructure 2 which is secured in the front and rear of the frame 3 of the vehicle 2 by a safety device.

The securing device - FIG. 2 consists of two claws 2 which are pivoted by the pivot pins 5 of the frame 2 of the carriage 2 by the left and right arms 7 through the bolts 23 connected to the rods. The tie rods 9 are coupled to the rocker 10 by the axes 9 mounted on the shaft 1d. The rocker 10 is rigidly coupled to the lever 12. The lever 12 is a flange 24 connected to the piston rod 13 of the single acting air cylinder 14.

The air cylinder 14 has a piston rod 13 attached to the rubber membrane 15 and a compression spring 16 is threaded onto the piston rod 13. The air cylinder 14 is mounted on the frame 2 of the vehicle 1 and is connected to the air distribution of the vehicle 2 via a valve 21 located in the driver's cab.

On the left arm 6 there is an aperture 17 through which the screw 18 is screwed into the frame 3 of the vehicle 2 while the right arm 2 is oriented opposite the switches 19 housed in the frame 2 of the vehicle 2

The claws 2 have bevel surfaces 20 provided on the upper portion to allow the superstructure 2 to be stored.

When driving the vehicle 2, in some cases the superstructure outside the frame 3 of the vehicle 2 must still be secured - secured against any spontaneous movement. Before driving, the operator rotates the valve 21 to the "locked" position and thereby connects the pressure chamber of the air cylinder 14 to the atmosphere. The compression spring 16 through the piston rod 21, lever 12, rocker arm 10, rod 2 and left 6 and right arm 7 rotate the teeth 2 which press through the bearing surfaces 22 of the superstructure 2 to the vehicle frame 3.

Conversely, when working with superstructure 2, the operator, by turning the valve 21 to the "unlocked" position, connects the pressure space of the air train 14 to the air distribution of the vehicle 2, whereby the pressure air in the direction of the arrow shifts the rubber diaphragm 15 with the piston rod 13 and compresses the compression spring 16. the claws 2 rotate and release the superstructure 2 from the frame 2 of the vehicle 2 ·

Claims (3)

3 258214 Then the superstructure 2 can be freely manipulated. In the event that the operator inadvertently rotates the valve 21 to the "locked" position and the superstructure 2 is not in the down position or there is a defect in the air distribution, there will be no accidents because the teeth 4 will slip through the bevel surfaces 20 of the teeth 4. they overcome the resistance of the compression spring 16 and engage the abutment surfaces 22 of the superstructure 2. In the event of a failure of the air distribution of the vehicle 1, the claws 4 can be unlocked manually so that the operator presses the left arm 6 by turning the screw 18 and thereby releasing the two teeth. The spring 16 is compressed in the air cylinder 14. The object of the invention A superstructure securing device on a vehicle that is arranged on a vehicle frame perpendicular to the vehicle axis in the space of the front and rear of the superstructure, characterized in that the claws (4) which are pivoted by the bolts (5) are mounted on the frame (3) of both sides of the vehicle (1) and the teeth (4) are left-hand (6) and right-hand (7) through the bolts (23) connected to the rods (8), which are coupled with the axles (9) to the rocker (10) mounted on the shaft (11) such that the rocker arm (10) is fixedly coupled to a lever (12) which is a hinge (24) connected to the piston rod (13) of the cylinder (14). 2. The safety device according to claim 1, characterized in that in the left arm (6) there is an opening (17) through which the screw (18) guided is screwed onto the frame (3) of the vehicle (1), while the right side (7) is oriented against the switches (19) housed in the frame (3) of the vehicle (1). Safety device according to clauses 1 and 2, characterized in that the teeth (4) have bevel surfaces (20) formed on the upper part. 1 drawing
