Problems solved by technology
[0004] In the existing engineering inspection, more and more attention is paid to the safety of the equipment. For example, the above-mentioned test equipment has safety measures such as setting a protective net on the frame, but there is no good safety guarantee when the anchor components are removed at both ends of the equipment. Because the anchoring component is tensioned by the pressure of the jack, when the anchoring effect between the steel strand and the anchoring component collapses, the anchoring component often falls directly; although this form has no effect on the anchoring test, it is not taken seriously , but it often damages the ground where the equipment is installed, resulting in pits, and there is a potential safety hazard of hitting people

Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the drawings.
[0028] This embodiment discloses an anchor strength test equipment, such as figure 1 As shown, the base 1 is included. The base 1 is provided with two opposite and parallel support bases 2, a number of support rods 3 are connected between the two support bases 2, and a protective net 20 that can be opened from the side or from above is installed. ; A jack 4 is fixed on the left support base 2, and the jack 4 is a through-type jack; the other support base 2 is fixed with a load sensor 5. During the anchoring strength test, the steel strand 18 passes through the jack 4, the support base 2, and the load sensor 5. The two ends of the steel strand 18 are connected to the anchoring assembly 17, and the anchoring assemblies 17 at both ends are against the jack 4 and the load sensor 5 respectively. The end face of the anchor assembly 17 is applied with a tensile force by the jack 4 ...

The invention discloses an anchoring strength testing device including a base, two parallelly arranged bearing seats are arranged on the base, the opposite sides of the two bearing seats are provided with a jack and a load sensor respectively, a protection net is arranged between the two bearing seats, the sides where the jack and the load sensor are arranged are slidably provided with protection devices, each of the protection devices includes a slide seat axially slipping along the jack, the slide seat is provided with a swing mechanism and a cover body connected with the swing mechanism, one end of the cover body is opened, the cover body forms a protection state or a discharging state through the swing of the swing mechanism, when in the protection state, the opening of the cover body abuts against the end face of the jack or the end face of the load sensor to form a protection bin, and when in the discharging state, the opening of the cover body faces upwards, and the inner side wall of the cover body is provided with an inclined surface for guiding the dropped anchoring component to slip to the bottom of the cover body when in the protection state. The anchoring strength testing device improves the safety in the testing process.
Description
Technical field [0001] The invention relates to the technical field of engineering inspection, and more specifically it relates to an anchoring strength test equipment. Background technique [0002] The key to the use of prestressed tendons in concrete engineering is the anchoring component. The anchoring performance of the anchoring component is an important indicator of the engineering safety performance. Therefore, the anchoring component needs to have a strong bearing capacity and good adaptability. [0003] The Chinese patent document with the authorized announcement number CN203132856U in the prior art discloses a static load anchoring experimental device, which consists of a frame, and two ends of the frame are respectively installed with jacks and load sensors; during the test, the steel strand is passed through the jacks , Frame, load sensor, and then connect the anchoring components at both ends of the steel strand, push the anchoring component through the jack to cause t...
