Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber waterstop strength testing, and in particular to a rubber waterstop strength testing device. Background Technology
[0002] During the production of waterstops, several sections are selected from different locations and cut for strength testing. Workers assist with the testing process. However, since waterstops are relatively thick, if the quality is not up to standard during testing, they may break midway and cause injury to the workers. Therefore, based on this problem, we designed a rubber waterstop strength testing device. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a rubber waterstop strength testing device, including a fixed tensioning device and a movable tensioning device; the fixed tensioning device includes a support platform and a clamping block, the clamping block is driven by a first hydraulic cylinder on the upper side to clamp one end of the rubber waterstop; the movable tensioning device includes a housing, an insertion fixing groove, a lower fixing block and an upper fixing block; the lower fixing block is fixed to the lower side of the insertion fixing groove, and a mounting plate in the shape of a "∏" is provided above the upper fixing block, the upper fixing block is installed in the middle groove of the mounting plate; the two ends of the upper side of the mounting plate are provided with rotating shafts, the rotating shafts are inserted into the housing, and the upper fixing block is clamped and released by rotating the mounting plate; a second hydraulic cylinder is provided on the side of the housing away from the fixed tensioning device, and the second hydraulic cylinder is provided with a tension digital display.
[0004] The support platform is provided with a limiting groove for placing the rubber waterstop.
[0005] The bottom of the clamping block is evenly provided with multiple clamping cones.
[0006] The rotating shafts at both ends of the mounting plate pass through the outer shell. A swing plate in the shape of a "∏" is provided on the upper part of the outer shell. The lower part of the swing plate is fixedly connected to the rotating shafts passing through the outer shell. A third hydraulic cylinder is hinged to the upper end of the outer shell. The hydraulic rod of the third hydraulic cylinder is hinged to the upper part of the swing plate. The upper fixed block is driven to swing and press tightly by the third hydraulic cylinder.
[0007] The opposing sides of the lower and upper fixing blocks are both arc-shaped.
[0008] The beneficial effects of this utility model are as follows:
[0009] This device first secures one end of the rubber waterstop to the tensioning device, then places the relaxed end into the insertion slot of the outer casing. At this point, the upper fixing block is in a raised state, and the third hydraulic cylinder pushes the upper fixing block downward to clamp it. Workers stand at the second hydraulic cylinder on the rear of the large outer casing to observe the tension display and thus test the strength. The testing is safe and efficient.
