In one embodiment, referring to fig. 1, a tension testing apparatus 100, the tension testing apparatus 100 includes: at least two fixed structures 110, an assistor 120, and a tension meter 130. At least two fixing structures 110 are arranged on the base 200 at intervals, and a force-receiving tool 300 is connected between two adjacent fixing structures 110. The assistor 120 is located between two adjacent fixed structures 110, and the assistor 120 is used for applying a tensile force to the force-receiving tool 300. The tension meter 130 is located between two adjacent fixing structures 110, and the tension meter 130 is used for testing the tension on the force-receiving tool 300.
In the tensile test apparatus 100, the fixing structures 110 are separately mounted on the base 200 during the tensile test; connecting the force-bearing tool 300, the force adder 120 and the tension meter 130 between two adjacent fixed structures 110; after assembly, a tensile force is applied to the force-receiving tool 300 by the force multiplier 120. When the reading on the tension meter 130 reaches the predicted force, the stress of the stress tool 300 is kept for a preset time, and after the preset time, the appearance change of the stress tool 300 is observed and the current reading on the tension meter 130 is read, so that the detection of the tension tolerance value of the stress tool 300 is completed. Compared with the traditional large-scale test equipment, the device adopts the three structures of the fixed structure 110, the booster 120 and the tension meter 130 to complete the tension test, simplifies the structure of the tension test device 100, reduces the occupied space of the device, and greatly facilitates the operation personnel to test the stressed tool 300 in time. Meanwhile, when the base 200 is a structure in a construction site, such as a steel rail 210 and the like, the tensile testing device 100 is arranged in the construction site at any time through the fixing structure 110, so that an operator can perform tensile testing operation at any time, hidden defects of the stress tool 300 and stress threads are found in time, and personal and operation safety is effectively guaranteed.
It should be noted that the connection of the force-receiving tool 300 between two adjacent fixing structures 110 should be understood as follows: the force-receiving tool 300 is tensioned between two fixed structures 110, and the force-receiving tool 300 may be directly connected to the fixed structures 110 or indirectly connected to the fixed structures 110. Such as: one end of the force-bearing tool 300 is directly connected to the fixed structure 110, and the other end of the force-bearing tool 300 is indirectly connected to the fixed structure 110 through the assistor 120 and/or the tension meter 130; alternatively, one end of the force-receiving tool 300 is indirectly connected to the fixed structure 110 through the force adder 120, and the other end of the force-receiving tool 300 is indirectly connected to the fixed structure 110 through the tension meter 130. Wherein, the force-bearing tool 300 is a tool to be tested, such as: the force-bearing tool 300 is a safety belt, a wire rope, a chain, or the like.
It should be noted that the number of the fixing structures 110 of the present embodiment may be at least two, and when there are two fixing structures 110, the worker may perform a single tensile test between the two fixing structures 110. When the number of the fixing structures 110 is more than three, the operator can perform more than two tensile tests at the same time, thereby greatly improving the test efficiency of the stress tool 300. In addition, the base 200 of the present embodiment has various structures, such as: tables, stools, slates, rails 210, and the like. Of course, when the base 200 is the steel rail 210, the operator can use local materials, so as to reasonably utilize the field resources, avoid additional preparation of the base 200 structure, and greatly facilitate the test of the stress tool 300.
Alternatively, the assistor 120 is a lever block, a motorized block, a turnbuckle, a lever ratchet tightener, or the like.
Specifically, referring to fig. 1, the force-receiving tool 300, the force adder 120 and the tension meter 130 are sequentially connected in series, and then connected to two adjacent fixing structures 110 after being connected in series. The connection between the one end of the force-bearing tool 300 and the fixing structure 110 may be binding, hooking, or bolting. The tension meter 130 is connected to the fixing structure 110 by a hook connection.

The two adjacent supporting components 113 are used for connecting the force-bearing tool 300. The locking assembly 112 is used to lock the base 111 to the base 200. During the tensile test, the base 111 is placed on the base 200; the base 111 is stably fixed on the base 200 through the locking assembly 112; after the base 111 is fixed, the stress tool 300, the booster 120 and the tension meter 130 are respectively connected to two adjacent supporting components 113; applying a pulling force to the stress tool 300 to a predicted force through the assistor 120, and keeping the stress tool 300 stressed for a preset time; finally, the change in the force-receiving tool 300 and the current reading on the tension meter 130 are observed, thus allowing the tension test of the force-receiving tool 300 to proceed stably.
It should be noted that the locking assembly 112 can lock the base 111 to the base 200 in various ways, such as: the locking assembly 112 is a hoop assembly, and the base 111 is hooped on the base 200 in a hoop mode; alternatively, the locking assembly 112 is a bolt assembly, and the base 111 is screwed to the base 200 by a screw connection method.
Optionally, the support assembly 113 is mounted on the base 111 by bolting, pinning, snapping, riveting, welding, etc.

Draw-in groove 1116 is used for going into base 200, so can know, in the installation, base 111 goes into on base 200 through draw-in groove 1116 card, increase the bonding strength between base 111 and the base 200, avoid base 111 to place on base 200 surface and easily lead to base 111 unstability, so, through draw-in groove 1116, make the installation of fixed knot structure 110 on base 200 more stable, thereby make the tensile test of atress instrument 300 more reliable, be favorable to improving the accuracy of tensile test result.
In one embodiment, referring to FIG. 2, the locking assembly 112 includes a first locking member 1121. First locking members 1121 extend through opposing walls of slot 1116 and first locking members 1121 are used to capture the walls of slot 1116 to base 200. When the base 111 is clamped into the base 200 through the clamping groove 1116, the two opposite groove walls of the clamping groove 1116 are penetrated through the first locking piece 1121, so that the two groove walls are mutually close under the action of the first locking piece 1121, the base 200 is clamped, the base 111 is more stably installed on the base 200, the accuracy of a tensile test is further improved, the hidden defects of the stress tool 300 and stress threads are found in time, and the personal safety and the operation safety are guaranteed.
It should be noted that, referring to fig. 2, the first locking member 1121 penetrates through two opposite groove walls of the clamping groove 1116 to form a first through hole 1117 on each of the two opposite groove walls of the clamping groove 1116, and the first locking member 1121 penetrates through the first through hole 1117. Wherein, first retaining member 1121 is located all spiro union nut or nut on the both ends outside draw-in groove 1116, through nut or nut, with first retaining member 1121 stable connection on the two relative cell walls of draw-in groove 1116.
In one embodiment, referring to fig. 2, two interference portions 1115 are disposed on the base 111 at intervals. The two interference parts 1115 are respectively located at two opposite sides of the clamping groove 1116. Interference section 1115 is for interference fit with the flange of base 200. When base 111 passes through draw-in groove 1116 card on base 200, two conflict portions 1115 are located base 200's relative both sides respectively, and conflict portion 1115 conflicts on the edge of a wing of base 200, effectively avoid base 111 atress and break away from base 200 in the experimentation, guarantee that the tensile test of atress instrument 300 goes on steadily for the accurate recessive defect of discovering atress instrument 300 and atress clue of operation personnel, guarantee the personal and operation safety.
It should be noted that the flanges of the base 200 are protruding portions on two opposite sides of the base 200, such as: when base 200 is rail 210, the flanges of rail 210 are the tops of rail 210 that protrude beyond the web of rail 210.
Alternatively, the abutting portion 1115 may be integrally formed on the base 111, bolted, welded, or the like. Wherein, the integrated molding mode is casting, die casting, extruding, forging and the like.
Further, referring to fig. 2 and 3, the locking assembly 112 further includes a second locking member 1122. The second locking member 1122 is mounted on the base 111. One end of second locking member 1122 abuts against the side of base 200 opposite to abutting portion 1115. Therefore, when the second locking member 1122 abuts against the base 200, the second locking member 1122 and the abutting portion 1115 cooperate to form two opposite acting forces for the base 200, so as to respectively apply pressure to the upper and lower sides of the base 200, thereby effectively preventing the base 111 from shaking up and down on the base 200, and thus enabling the force-receiving tool 300 to perform a stability test between the two fixing structures 110. Meanwhile, the second locking member 1122 fixes the fixing structure 110 and the base 200 into a whole, so that the fixing structure does not slide when being subjected to an external force, thereby maintaining the installation stability.
It should be noted that the way one end of the second locking member 1122 abuts against the base 200 is: the base 111 is provided with a second through hole 1118, and the second locking member 1122 passes through the second through hole 1118 and abuts against the base 200. Meanwhile, the second locker 1122 may be mounted on the base 111 by a screw or a snap connection. When the second locking member 1122 is connected to the base 111 by means of a snap-fit, a plurality of protrusions or locking holes are formed on the second locking member 1122 along the length direction of the second locking member 1122 at intervals.
Specifically, referring to fig. 3, the second locking member 1122 is a screw or a bolt, and the second locking member 1122 is screwed in the second through hole 1118. By rotating second locking member 1122, second locking member 1122 is gradually moved downward and urged against base 200 by the threads.
