Abstract

The invention is related to improvement, production and implementation of the technical benefits of the safety pins in the ring parts in the rims of heavy construction equipment and special equipment machines consisting of many structural components and having locking property.

Description

RING LOCKING PIN USED IN RIMS

Technical Field

State of the Art

The invention is the safety pin part as a structural element which ensures that the ring parts manufactured for various purposes today and assembled in heavy construction equipment and special equipment machine rims consisting of multiple structural components are locked.

In the prior technique, locking mechanism on the ring consists of perforated pin, plate washer and hook-shaped needle. Integrated form of said parts is known as rim fastener or clasp. One end of the safety pin as the element of locking mechanism for the rim is manufactured in flat shape and the other end is manufactured in hook shape.

Perforated pin is assembled by welding through the holes on the ring bored in such a way that one hole is made on its opposite ends by taking defined measurements as a reference. Plate washer is inserted on said perforated pin in smooth alignment and in this way, plate washer is fastened on perforated pins. After plate washer is fastened, smooth part of the safety pin is passed through the holes of said pin welded on the holes bored on the ring. Perforated pin is assembled by fixing it on the hooked part on the other end of said safety pin. Tire pressure may decrease due to external factors during use of construction equipment and special equipment machines. With this application, potential change on the positions of removable parts of tire and rim and sliding, dislocation or displacement over the teeth of the wheel rim of the ring part with open end are prevented thanks to the parts called ring fastener/clasp. Thus, moving vehicle performs its function safely and financial and labor loss is eliminated. Object of the Invention

Ring fastener/clasp designed with prior technique may split off the hook of said safety pin as a result of potential changes in the conditions of working environment. Plate washer may fall down over perforated pins due to said dismantling. Main object of invention is to prevent said dismantling situation and ensure continuation of ring locking system.

Yet, due to decrease in tire pressure during operation, position of removable parts of tire and rim may change and said parts may be slid, dislocated or displaced over the wheel rim teeth of the ring part

Uncontrolled dismantling problem will be eliminated with new design in snail shape by making design change on the opposite hooked end where smooth part of the safety pin designed in prior technique.

Ring parts inside the rims of construction equipment and special equipment machines consisting of multiple structural components include structural components called ring used for various purposes. Rings may be exposed to imbalanced mechanical forces on the relevant rims due to change of various environmental conditions during the operations of said machines. Thus, ring may leave its position and cause dangerous situations.

Safe operation of the rim and the vehicle is ensured by fixing the ring fastener/clasp (20)parts constituting the ring part locking mechanism (10) displayed in Figure 1.

Ring locking mechanism (10) mainly consists of ring fastener/clasp (20) depending on the design preference of the manufacture. Ring fastener/clasp (20) consists in detail of perforated pin (30) fixed on both ends of the ring part, plate washer (40) fixed on perforated pin (30) and safety pin (50) used in order that plate washer (40) can remain in fixed position.

Holes are bored on the ends on the ring part by equipment according to the predefined measurements in such a way that said holes remain opposite each other. Perforated pin (30) is assembled in such a way that it coincides with said holes. Ring fastener/clasp (20 parts are fixed so that they (20) are positioned at the same axis. Both ends of the perforated pin (30) mounted on the ring may not keep their fixed positions and is dislocated due to various environmental conditions. In order to eliminate this problem, slot-holed plate washer (40) with one circular side and the other in harmony with pre-defined reference measurements are fixed on perforated pin (30). Pictures of the ring fastener/clasp (20) elements are provided separately from each other in FIGURE-2. In addition to perforated pin (30) and plate washer (40), safety pin (50) is among said elements too. Safety pin (50) has ends with two different geometric forms in smooth end (53) and hook (52) shapes. Smooth end (53) of the safety pin (50) is passed through the hole on perforated pin (30). After smooth end (50) is passed through the hole on perforated pin (30), it is inserted into the hook (52) and thus, perforated pin (30) is locked.

Machine rims used in the operations under field conditions have a tendency to free from mechanism with this type of assembly. In the working conditions such as off-road, soil, debris where working conditions are unsuitable, hook (52) part of the safety pin (50) is disengaged from the part with smooth end (53) and accordingly, it loses its locking characteristic after plate washer (40) falls down.

Under these circumstances, ring locking mechanism (10) is deactivated. Pressure decrease in the tires depending on the application and operation conditions cause removable parts of the ring located on the rim to be removed from their positions. Furthermore, sliding, dislocation or displacement of the rim over the teeth of the wheel rim owing to unfolding of the ring ends cause serious occupational accidents to occur.

Pictures in which the hook (52) on the safety pin (50) is modified and snail shape is given are provided in Figure-3. Snail shape with a width through which smooth end (53) of the safety pin (50) can pass is provided to the hook (52) by bending it (52) at least 1,5 cycle towards the center of the safety pin (30). Smooth end (53) of the safety pin (50) used to fix the perforated pin (30) and the plate washer (40) on it passes respectively through the hole of the perforated pin (30) and the space occurred after snail shape is given to the hook (52). Smooth end (53) inside the snail-shaped hook (52) as the subject of the invention is not dislocated under the application and field conditions. The reason for this is that if the smooth end (53) inside the snail-shaped hook (52) is to be removed, snail-shaped hook (52) must be rotated at least for 1,5 cycle towards outside the center of the safety pin (50).

Dismantling of the safety pin (50) as a result of the changes in field and operating conditions and potential safety-sourced risks are eliminated thanks to said invention.

Claims

1. A safety pin used in machine rims, characterized in that; the hook (52) fixed inside the safety pin (50) is snail-shaped in order that the smooth end (53) on the safety pin (50), ring fastener/clasp can be fixed
