HU204002B - Carriage for manual flame cutting apparatus - Google Patents

Abstract

A trolley may be used with any type of manual flame cutting gun. It may be moved manually or by a low voltage electric motor. The trolley comprises: tubular frame, mechanism housing, driver arm 2-step drive wheel and endless drive belt, heat guard for the drive belt.

Description

Scope of the description: 4 pages (including 2 sheets)

EN 204002

The object of the application is a trolley for hand flame cutting equipment, for cutting the cutting quality, thereby reducing post-processing and saving the gas used for cutting.

Targeted devices known to me and their operation are described by Árpád Endre: The Technology of Welding of Flame in 1971 published by Technical Publisher. page. The semi-automatic flame cutting motors described here are designed to prevent heavy workpieces from being transported to the machine, and cutting is done on-site. It is a KADETT type engine with a weight of approx. 8 kg. The structure known as the SECTOR is the closest to the invention, the mass of which exceeds the type of KADETT.

The area of application of the SENATOR is quite large, but its price and weight, as well as the way of driving a forced course, strongly influence the field of application

Therefore, the object of the invention I have announced is to design a trolley with a smaller weight, which is easy to handle, and the cutting line is not limited, it can be easily moved.

The object of the present invention is therefore to provide a trolley that meets the above requirements.

The essence of the object trolley is that it can be mounted on any type or structure, whether it is a front-end torch, up to 90-degree torch, therefore a double-sided assembly box, rear knee support, clamping bracket, multi-stage gear wheel driven by a hand crank and a driven impeller connected to it via an infinite drive cord arranged in a heat shield. has a fork clip and a flame shield.

I will describe the carriage according to the invention on the basis of the attached drawings, without limiting the scope of protection to the following:

Figure 1 Front view of front drive

Figure 2 is a side view of a manual gearbox and a rear wheel support

Figure 3 Front view of front head

Figure 4 is a manual gearbox with rear wheel support and gearbox in top view

Figure 5 is a top view of a gearbox and a backrest with an electric motor

Fig. 1 and Fig. 2 show a side view of the construction and embodiment of the carriage according to the invention

Fig. 3 and Fig. 4 show a top view, with a manual drive.

The double-sided (5) mounting frame is equipped with the driven impeller, the flame guard 2, the tension spring 3, the grease nipple, the clamp 14, and the drive wheel. The connecting frame and the support frame tube 9 are connected to the assembly frame 5, with the fork clamp 6, and the cable guide wheel 10, the multi-stage drive wheel 11, the crank 12, and the rear wheel support 13. The heat shield 7 is also connected to the mounting frame 5 in which the endless drive line 8 is disposed. The version with a low voltage electric motor is shown in Figure 5 in top view. The drive shaft 16 and the drive motor 15 are connected to the shaft of the manual crank 12. The operation of the above described trolley can be characterized by connecting the trolley with the clamp 14 and the latch 6 to the torch. The clamping clamp 14 can be adjusted arbitrarily for the front cutter and the different angle cutter as well as for the various torches. The driven impeller 1 is driven by the endless drive line 8 via the manual crank 12 or through the gearbox 16 via the low-voltage electric motor 15 through the multi-stage drive wheel 11 and the guide wire 10, the tension spring 3 being to provide the front drive impellers 1 located on the mounting frame 5 to the impeller. it can be adjusted to a suitable adhesive force in relation to the materials to be cut with different surface roughness. The grease nipples 4 are used to lubricate the shaft of the driven wheels. The purpose of the flame shield 2 is to protect the driven impellers from splashing sparks or tread materials.

In summary, the structure of the trolley and its handling and operation meet the objectives set out in the task.

Claims (2)
