TH4880A - Vehicles for transporting goods, including equipment for measuring the safety of load tilting on such vehicles. - Google Patents

Abstract

A transport vehicle with a lifting and lowering platform (6) for the load and with at least three lifting cylinders (3) for the platform (6) and supported on the frame and articulated to the frame and the platform (6) and the intermediate platform (5), respectively, with at least two guide bolts (4) articulated to it and positioned in the direction of the internal height of the frame or on the frame. It should be noted that at least one guide bolt, or the connection area for connecting the guide bolts to the platform (6) or to the intermediate platform (5), respectively, shall be supported by a bearing area (12) to allow it to slide in the direction of the connection line (11) of the guide bolt edge axis (4) and to perform safety measurements, specifically safety against tilting of the load on the transport vehicle. The lifting cylinder (3) or its pressure pipe shall be connected to a pressure sensing device and the value of the measured pressure shall be Send to the switching device, specifically the comparator device. If the pressure inside the lifting cylinder (3) drops below the estimated pressure, a pressurized fluid source is switched to that location to adjust the actual pressure to match the estimated pressure inside the lifting cylinder (3).

Claims (10)

1. A transport vehicle, especially a slow-moving transport vehicle, shall consist of a lifting platform capable of being raised and lowered, and at least three lifting cylinders for the platforms supported on the frame, characterized by the lifting cylinder (3) being articulated to the frame (2) and articulated to the platform (6) or the central support (5) respectively, and at least two guide bolts (4) positioned within or on the frame (2) in the height direction shall be articulated to the platform (6) or the central support (5) respectively. It should be noted that at least one guide bolt (4), or the connection area (10) for connecting the guide bolt (4) to the platform (6) or the central support (5) respectively, shall be supported to allow sliding movement in the direction of the connection(11) of the axis of the guide bolt (4). 2. The vehicle for transporting under claim 1 shall be characterized as having at least four lifting cylinders (3). 3. The vehicle for transporting under claim 1 or 2 has the characteristic that the connection line (11) of the guide pin axle (4) is symmetrical with respect to the arrangement of the lifting cylinder (3). 4. The vehicle for transporting under claim 1, 2, or 3 is characterized in which the lifting cylinder (3) is attached to the swivel bearing (13) in such a manner as a swivel joint in the frame (2) and the central support (5) connected to the lead bolt (4), and in such a manner as the support (6) is supported rotatably on the central support (5). 5. The vehicle for transporting under claim 4 has the characteristic that the central support platform (5) supports a drive motor (15) which is a drive device to rotate the support platform (6). 6. The vehicle for transporting under claim 4 or 5 shall be characterized in which the central support (5) is secured by at least three (18) rollers capable of raising and lowering the support (6) during operation. 7. Any of the transport vehicles under claims 1 through 6 have the characteristic that four lifting cylinders (3) are connected in a lever-like manner at positions near the corners of the central support (5) or the rectangular support (6), respectively. 8. An instrument for measuring safety, especially the safety of tilting loads for vehicles under any of the claims 1 through 7, shall have the characteristic that the lifting cylinder (3) or its pressure pipe, respectively, is connected to a pressure sensing device (36) in such a way that the measured pressure value is transmitted to a switching device (38) in particular containing a comparative device, and in such a way that if the pressure inside the lifting cylinder (3) falls below the estimated pressure value, a pressurized fluid source can be switched to there to adjust the actual pressure to the estimated pressure value in the said lifting cylinder (3). 9. The instrument under claim 8 has the characteristic that a source of pressurized fluid can be switched to the cylinder for lifting (3) which has a minimum measured pressure value. 10. The instrument according to claim 8 or 9 is characterized in such that it is provided with an independently programmable slitting device (38) which calculates the position of the center of gravity of the load from the measured pressure values, and in such such a way that the source of pressurized fluid to be delivered to each lifting cylinder (3) can be controlled depending on its actual position and depending on the approximate position of the pointer of the center of gravity of the load to the support (6) (Clause 10, page 2, figure 14).
