Description

A special tool for replacing idlers on belt conveyors

Technical field:

The utility model relates to a special tool for replacing idler rollers on belt conveyors, in particular to metallurgy, mining, construction, transportation and other industries for replacing idler rollers on belt conveyors. the

Background technique:

It is a routine operation in the production process to replace the upper roller of the belt conveyor. A 100-meter-long belt conveyor has nearly 300 upper rollers. Due to the wear and tear of the idler rollers and the damage of the idler roller bearings in continuous operation, it is difficult to avoid, and the replacement of the upper idler rollers has become an operation that must be carried out every shift. the

At present, crowbars are generally used to replace the upper idler, and there are problems: (1) Since the upper idler is located at the lower part of the belt, due to the tension of the belt, the upper idler is squeezed tightly by the belt, and 2-3 people are required for replacement At the same time, 1-2 people use crowbars to pry up the belt, and one person installs the roller. It is time-consuming and labor-intensive, and it is not suitable for the current mechanism where one person has multiple posts. (2) When prying the belt with a crowbar, it is limited by the site conditions. It is difficult for the crowbar to pry the belt to a position far away from the idler frame suitable for replacing the idler roller. Sometimes the operator must drill under the belt to install it, which may cause personal injury. (3) Without a stable fulcrum, the crowbar can only be placed on other rollers, which can easily cause the fulcrum to slip, posing a safety hazard. the

Invention content:

In order to overcome the deficiencies of the prior art, the utility model provides a special tool for replacing idler rollers on a belt conveyor, which is easy to operate, safe and reliable, and adapts to the multi-post system for one person, saving labor costs. the

The utility model provides a special tool for replacing idler rollers on a belt conveyor, including a crowbar. The 90-120° angle transitions smoothly, and a bracket is provided on the straight section of the crowbar. the

One end of the crowbar and the lower end of the bracket are welded with a base. the

The support is a foldable support, and the support is connected to the crowbar with a U-shaped connecting plate and bolts. The connecting plate is provided with a limiting plate, and the support can be folded toward the inside of the crowbar. the

The utility model provides a special tool for replacing the idlers on the belt conveyor, setting a reasonable fulcrum for the crowbar, adding a movable support for the crowbar, and setting up two bases to increase the operational stability and avoid potential safety hazards; Labor cost; no need for people to drill under the belt, which improves the safety operation factor; shortens the replacement time and reduces labor intensity. the

Below in conjunction with accompanying drawing and embodiment the utility model is described further. the

Description of drawings:

Fig. 1 is a structural diagram of the utility model. the

Among the figure, 1 is a crowbar; 2 is a bracket; 3 and 4 are bases; 5 is a U-shaped connecting plate; 6 is a bolt. the

Detailed ways:

Embodiment: As shown in Figure 1: the two end points of the crowbar 1 are not on the same straight line, one section of the crowbar 1 is straight, and the other section forms a smooth transition at an angle of 90 to 120° with the straight section. The straight section of the flat section is provided with a bracket 2, one end of the crowbar 1 is welded with a base 3, the lower end of the bracket 2 is welded with a base 4, the bracket 2 is connected to the crowbar 1 through a U-shaped connecting plate 5 and bolts 6, and the connecting plate 5 is provided with a There is a limit plate, so that the support 2 can be folded to the inside of the crowbar 1. the

Take the implementation of the material supply operation area of Taiyuan Iron and Steel Plant as an example: 

(1) Use a steel pipe with a diameter of 30 mm and a length of 1.8 meters as a crowbar, and one end of the crowbar is bent to form a smooth transition at an angle of 100 degrees to the straight section of the crowbar. The height of the bending section should be determined according to the vertical height of the middle upper roller of the belt and the longitudinal belt frame, that is, the vertical height formed by the bending section of the crowbar should be ≤ the vertical height of the middle upper roller of the belt and the longitudinal belt frame (about 300mm). the

(2) Use the same type of material to set a bracket at the other end of the crowbar, and the height of the bracket is greater than the vertical height of the curved section of the crowbar. The length of the bracket and the installation position on the crowbar are determined when the belt is pried up by the crowbar to a reasonable position for replacing the idler roller. the

(3) Use channel steel to weld a base at the lower end of the crowbar and the bracket respectively. When prying up the belt, the two bases are evenly stressed, which is conducive to enhancing the stability of the crowbar. the

(4) The bracket and the crowbar are connected with a U-shaped connecting plate and bolts, and a steel plate with a height of 30 mm and a thickness of 6 mm is welded on the outside of the connecting plate as a limit plate, so that the movable bracket can only be folded towards the inside of the crowbar. Stable and easy to carry. the
