Description

Technical Field

[0001] The utility model relates to the technical field of steel bar detection equipment, in particular to a steel bar tensile strength detection device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is round, and sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. Before the steel bars are put into use, their strength needs to be tested, so a special strength testing device is used.

[0003] A tensile strength testing machine is disclosed in the Chinese utility model patent with the announcement number CN219265931U. The device uses two steel bar clamping mechanisms to tightly fix the two ends of the steel bar, which can effectively prevent the steel bar from falling off during the tensile test. The feeding mechanism is used to facilitate the delivery of the steel bar to the side of the steel bar clamping mechanism, so as to achieve rapid loading and reduce physical consumption. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, at the moment of steel bar breaking, the balance between it and the clamp will be suddenly broken, making it easy for the steel bar to fall off the clamp and collapse. In addition, since the device lacks an integrated protective structure, it is easy to pose a hidden danger to the safety of the inspectors. For this reason, we provide a steel bar tensile strength testing device. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1.

[0019] 2. When the protective shell is driven to move vertically downward, the utility model utilizes the meshing action between the tooth plate and the gear to drive the rotating shaft to rotate. The rotation of the rotating shaft drives the two sets of baffles to deflect inward at the same time, so that the collection box can be closed to receive the broken steel bars and fragments, thereby facilitating the recovery of the steel bars. Conversely, when the protective shell is driven to move vertically upward, the collection box can be automatically opened to discharge the broken steel bars and fragments, which is highly practical.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. Example

[0027] Please combine Figure 1-4 , a steel bar tensile strength detection device of this embodiment includes:

[0028] A testing platform 1, a hydraulic cylinder 2 is symmetrically fixedly installed on the top of the testing platform 1, a placing platform 3 is fixedly installed at the telescopic end of the hydraulic cylinder 2, and a guide rod 4 is symmetrically fixedly installed on the top of the testing platform 1 and is slidably connected to the placing platform 3, which can guide the horizontal movement of the placing platform 3;

[0029] A protection component, the protection component includes a slide bar 101 symmetrically fixedly installed on the top of the detection platform 1, a slide plate 102 is symmetrically slidably connected to the outside of the two sets of slide bars 101, a connecting plate 103 is arranged above the detection platform 1, a protection shell 104 is arranged below the connecting plate 103, a connecting rod 105 is hinged between the slide plate 102 and the connecting plate 103 through a hinge, a vertical rod 106 is fixedly connected to the outside of the telescopic end of the hydraulic cylinder 12, and a connecting rod 2 107 is hinged between the vertical rod 106 and the slide plate 102 on the opposite side thereof through a hinge;

[0030] The protection components also include:

[0031] Four groups of connecting rods 108 are symmetrically fixedly connected to the top of the protective shell 104. The connecting rods 108 pass through the connecting plate 103 and are slidably connected thereto. A spring 109 is sleeved on the outside of the connecting rods 108. Both ends of the spring 109 are respectively fixedly connected to the connecting plate 103 and the protective shell 104. A limiting ring is fixedly sleeved on the upper outer side of the connecting rods 108 to prevent the connecting rods 108 from detaching from the connecting plate 103.

[0032] The collecting component includes a slot opened on the top of the testing platform 1, a collecting box 201 is fixedly installed at the bottom of the slot, a baffle 202 is symmetrically connected to the bottom of the collecting box 201 via a rotating shaft, a gear 203 is coaxially fixedly connected to one end of the rotating shaft, and a toothed plate 204 is symmetrically fixedly installed on one side of the protective shell 104 and is meshed with the gear 203 on the same side.

[0033] The implementation principle of a steel bar tensile strength detection device in the embodiment of the present application is as follows: first, both ends of the steel bar are placed on two sets of placement platforms 3 at the same time and fixed, and then the hydraulic cylinder 12 is started. When the hydraulic cylinder 12 drives the two sets of placement platforms 3 to move back to each other at the same time to stretch the steel bar, the vertical rod 106 and the hinged action of the slide plate 102 and the connecting rod 107 are utilized, and the sliding cooperation of the slide plate 102 and the slide rod 101 can drive the two sets of slide plates 102 to move toward each other, and under the hinged action of the slide plate 102 and the connecting rod 105, the protective shell 104 can be pushed downward, so that the steel bar can be covered, so as to play a protective role when the steel bar is broken. At the same time, the meshing action between the tooth plate 204 and the gear 203 can be used to drive the rotating shaft to rotate. The rotation of the shaft drives the two sets of baffles 202 to deflect inward at the same time, so that the collection box 201 can be closed to receive the broken steel bars and fragments. When the protective shell 104 contacts the detection platform 1, the two sets of baffles 202 are just in a horizontal state, which is convenient for the recovery of the steel bars. When the protective shell 104 contacts the detection platform 1, the sliding cooperation between the connecting plate 103 and the connecting rod 108 is used to make the connecting plate 103 compress the spring 109, so as to play a certain buffering role until the stretching of the steel bars is completed. Finally, after the tensile test is completed, the hydraulic cylinder 2 is controlled to push the placement platform 3 to reset. During the resetting process, the protective shell 104 can be driven to move vertically upward, and the two sets of baffles 202 can be driven to deflect outward at the same time to automatically open the collection box 201 to discharge the broken and collapsed steel bars.

A guide groove is provided on the top of the placing table 3, and a guide block is fixedly installed on the bottom of the movable clamping block 6 and is slidably connected to the guide groove, which can guide the horizontal direction of the movable clamping block 6. The movable clamping block 6 is pushed toward the fixed clamping block 5 by the hydraulic cylinder 2 7, so that the steel bars can be clamped and fixed, thereby ensuring the stable progress of the steel bar tensile test.
