Description

A bracket for replacing the blasting head of a shot blasting machine

technical field

The utility model relates to the field of steel processing, in particular to a bracket for replacing the blasting head of the shot blasting machine of a normalized pickling unit.

Background technique

The shot blasting machine system of Changhua pickling unit has 4 head blasting devices, 2 upper and lower, respectively responsible for breaking the surface of the upper and lower steel plates. After the cycle is used, the throwing head device needs to be replaced. The upper throwing head device can be easily hoisted out and put into the throwing head device by using a chain hoist; the lower throwing head device must use two chain hoists to bear opposite forces to lift the throwing head device out. Due to the narrow space, the operation is very inconvenient, and there are potential safety hazards. When the new throwing head device is installed, other tools are needed because it cannot be installed in place. It takes about 6 hours for 4 people to replace the lower throwing head device each time. The work is time-consuming and laborious, and there is a great potential safety hazard.

Contents of the invention

The technical problem to be solved by the utility model is: how to solve the problem of difficult replacement of the blasting head device of the shot blasting machine system of the normalized pickling unit.

The technical solution adopted by the utility model is: a bracket for replacing the shot blasting machine head, including a movable trolley, a hydraulic device installed on the trolley, and a support seat installed on the hydraulic support. The first support plate on the seat base, the second support plate on the support seat base, the third support plate on the support seat base, the first horizontal plate connected between the first support plate and the second support plate, the connection A second transverse plate between the second support plate and the third support plate.

As a preferred method: the top of the first support plate is an inclined surface at 14 degrees to the horizontal plane, the top of the second support plate is an inclined surface at 14 degrees to the horizontal plane, and the upper surface of the second horizontal plate is at an angle of 14 degrees to the horizontal plane. degrees, the upper surface of the first horizontal plate is the horizontal plane, the distance from the highest point of the first support plate to the horizontal plane is 432 mm, the distance from the highest point of the second support plate to the horizontal plane is 481 mm, and the highest point of the second support plate is 481 mm from the horizontal plane. The distance between the points and the second horizontal plate is 315 mm.

The beneficial effects of the utility model are: the utility model has the advantages of simple structure, convenient use, safety and reliability, and is applicable to the replacement operation of the throwing head device. After the utility model is implemented, the efficiency is obviously improved, the labor intensity is reduced, and the safety factor is greatly improved.

Detailed ways

As shown in Figure 1, a bracket for replacing the blasting head of a shot blasting machine includes a movable trolley, a hydraulic device installed on the trolley, and a support seat installed on the hydraulic support. The first support plate, the second support plate on the support base, the third support plate on the support base, the first plate horizontal plate connected between the first support plate and the second support plate, the second support plate connected plate and the second transverse plate between the third support plate. When it is necessary to replace the blasting head of the shot blasting machine, drag the device of the utility model to the bottom of the shot blasting machine frame, and after alignment, raise the hydraulic device so that the support seat fully supports the blasting head device, and the connecting bolt of the blasting device is to be disassembled Finally, the hydraulic device is lowered, and the throwing head device is completely separated from the equipment rack at this time. Pull the trolley to drag the head throwing device out and lift it away. The new head throwing device is hoisted on the support of the utility model, pushed to the bottom of the frame, and after alignment, the trolley is raised so that the head throwing device is installed in place, and the bolts are tightened to complete the replacement operation.

In order to better protect the shot blasting machine head and prevent the shot blasting machine head from being scratched by the bracket, the top of the first support plate is an inclined surface at an angle α to the horizontal plane, and the top of the second support plate is at an angle β to the horizontal plane. The inclined surface is in the best state when α angle = β angle = 14 degrees, the upper surface of the second horizontal plate is an inclined surface of 14 degrees with the horizontal plane, the upper surface of the first horizontal plate is a horizontal plane, and the first support The distance from the highest point of the plate to the horizontal plane is 432 mm, the distance from the highest point of the second support plate to the horizontal plane is 481 mm, and the distance from the highest point of the second support plate to the second horizontal plate is 315 mm. In this way, surface contact is formed between the shot blasting machine head and the utility model, which prevents the shot blasting machine head from being scratched by the support. The above dimensions are tested and most suitable for surface contact.
