Description

Technical Field

[0001] This utility model belongs to the technical field of grinding heads for hose abrasion testing machines, and particularly relates to a grinding head for a hose abrasion testing machine. Background Technology

[0002] Fire hoses are key components in automatic sprinkler systems, connecting sprinkler heads to distribution branch pipes. The main body is made of stainless steel, including the hose itself and installation components. They feature rapid installation, shock resistance, and anti-misalignment capabilities, and allow for flexible adjustment of sprinkler head height and spacing. They are widely used in office buildings, clean rooms, and other similar locations. According to regulations, these hoses are only suitable for wet systems in light hazard or medium hazard (Class I) locations, and must meet installation restrictions such as length and bending radius. Fire hoses require abrasion resistance testing during production and use, necessitating the use of a specialized testing machine. The grinding head is a crucial component of this testing machine; therefore, a hose abrasion resistance testing machine grinding head is proposed.

[0003] Existing testing machine grinding heads are inconvenient to adjust in height during use, and when grinding hoses, the grinding distance is often too far, reducing the accuracy of hose grinding. Furthermore, existing technical documents do not allow for multi-angle grinding tests on hoses; the grinding head can only perform single-angle abrasion tests, thus reducing the diversity of hose abrasion testing. Therefore, we propose a new grinding head for a hose abrasion testing machine. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a grinding head for a hose abrasion testing machine, thereby improving the accuracy of hose grinding and enhancing the diversity of hose abrasion testing.

[0005] In view of this, the present invention provides a grinding head for a hose abrasion testing machine, including a test chamber, and further comprising: an electric telescopic column through which the top of the test chamber is installed; a reciprocating mounting box fixedly installed at the bottom of the telescopic end of the electric telescopic column; a bottom lifting block fixedly installed at the top of the reciprocating mounting box; a top lifting block fixedly installed at the top of the interior of the test chamber; a balance bar through which the movable shafts of the bottom and top lifting blocks are installed; a suspension spring fixedly installed at the top of the balance bar; a counterweight block through which the balance bar is installed; a reciprocating mechanism fixedly installed inside the reciprocating mounting box; a guide rod fixedly installed at the bottom of the moving end of the reciprocating mechanism; a positioning guide block fixedly installed at the outside of the guide rod; a telescopic block fixedly installed on the surface of the guide rod; a guide rotating shaft fixedly installed at the bottom of the telescopic block; and a grinding head movably installed at the bottom of the rotating end of the guide rotating shaft.

[0006] Based on the above structure, the reciprocating mounting box is moved up and down by the telescopic end of the electric telescopic column. Then, the reciprocating mounting box is balanced by a balance bar and a counterweight. The balance bar is then cushioned and supported by a suspension spring, allowing for height adjustment of the hose grinding head for grinding, thereby improving the accuracy of hose grinding. Next, the reciprocating mechanism drives the guide rod to move left and right. Then, the telescopic block and the rotating end of the guide rotating shaft drive the grinding head to grind the hose at multiple angles, enabling multi-angle grinding experiments on the hose and thus increasing the diversity of hose abrasion resistance testing.

[0007] Preferably, a bottom mounting base is fixedly installed at the bottom of the experimental chamber, glass doors are movably installed on the surface of the experimental chamber via hinges, and a workbench is fixedly installed at the bottom of the experimental chamber.

[0008] Preferably, a bottom lifting mechanism is installed through the interior of the bottom mounting base. A bottom mounting plate is fixedly installed on the top of the telescopic end of the bottom lifting mechanism. A bottom bearing shaft is installed through the interior of the bottom mounting plate. A water tray is fixedly installed on the top of the rotating end of the bottom bearing shaft. A frame support block is installed through the exterior of the water tray. A style bracket is fixedly installed on the top of the frame support block.

[0009] Preferably, all the glass doors are made of tempered glass, and each glass door has a handle fixedly installed on its surface.

[0010] Preferably, an extension plate is fixedly installed on one side of the workbench, a pump mounting box is fixedly installed on the top of the extension plate, a test pump is installed through the inside of the pump mounting box, and a storage box is fixedly installed at the bottom of the workbench.

[0011] Preferably, a control panel is fixedly mounted on the surface of the pump mounting box, control buttons are fixedly mounted on the surface of the control panel, and a power socket is fixedly mounted on the bottom of the control buttons.

[0012] Preferably, the surface of the storage box is equipped with a storage door via a hinge, the surface of the storage door is fixedly equipped with a storage handle, the bottom of the storage box is fixedly equipped with a support base plate, and the bottom of the support base plate is fixedly equipped with an anti-slip pad.

[0013] The beneficial effects of this utility model are:

[0014] 1. The grinding head of this hose abrasion testing machine moves the reciprocating mounting box up and down via the telescopic end of the electric telescopic column. Then, a balance bar and counterweight are used to balance the reciprocating mounting box. A suspension spring is then used to buffer and support the balance bar. This allows for height adjustment of the hose grinding head during grinding, making it less likely to have a long grinding distance when testing hose abrasion, thus improving the accuracy of hose grinding.

[0015] 2. The grinding head of this hose abrasion testing machine moves the guide rod left and right through a reciprocating mechanism. Then, the grinding head is driven by the telescopic block and the rotating end of the guide rotating shaft to perform multi-angle grinding on the hose. This allows for multi-angle grinding tests on the hose, thereby improving the diversity of hose abrasion tests. Attached Figure Description
