Description

Technical Field

[0001] This utility model relates to the field of building safety assessment technology, specifically to a concrete pull-out instrument for building safety assessment. Background Technology

[0002] In the field of construction engineering, the safety of concrete structures is of paramount importance. As a commonly used connector in concrete structures, the anchoring effect of anchor rods directly affects the stability of the entire structure. To ensure project quality, it is necessary to use a concrete pull-out tester to test the pull-out performance of anchor rods.

[0003] In the process of developing this application, the following problems were found with this technology: The existing concrete pull-out tester is relatively simple in design and has a limited function for anchor pull-out testing. It can only be adapted to anchors with a specific outer diameter. In actual construction, due to the diversity and complexity of engineering design, the specifications of the anchors used are different. When faced with anchors of different outer diameters, the traditional pull-out tester cannot be flexibly adjusted. Testing personnel have to frequently change equipment or use additional adapters, which not only consumes a lot of time and manpower but also seriously affects the testing efficiency and delays the project progress.

[0004] Therefore, a concrete pull-out instrument for building safety assessment is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing concrete pull-out instruments are relatively simple in design and have limited functionality for anchor pull-out testing, only adapting to anchors with specific outer diameters. In actual construction, due to the diversity and complexity of engineering designs, various anchor specifications are used. When faced with anchors of different outer diameters, traditional pull-out instruments cannot be flexibly adjusted, forcing testing personnel to frequently change equipment or use additional adapters. This not only consumes a lot of time and manpower but also seriously affects testing efficiency and delays project progress. This invention provides a concrete pull-out instrument for building safety assessment.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A concrete pull-out instrument for building safety assessment includes a fixed plate. A control panel is mounted on the front of the fixed plate. A hydraulic cylinder is mounted on the inner wall of the front of the fixed plate. A tension detector is mounted on the output end of the hydraulic cylinder. A sliding plate is mounted on the end of the tension detector away from the hydraulic cylinder. A clamping mechanism for clamping multiple sets of anchor rods is mounted on the side of the sliding plate away from the tension detector. A support mechanism for supporting the use position of the fixed plate is engaged at the lower end of the fixed plate. A reset mechanism for resetting the position of the internal equipment of the clamping mechanism is mounted on the outer end of the clamping mechanism.

[0008] Furthermore, the clamping mechanism includes a fixed sleeve, which is installed on the side of the slide away from the tension detector. Slider blocks are slidably connected inside both the left and right sides of the fixed sleeve, and an annular sleeve is rotatably connected to the outer end of the fixed sleeve.

[0009] Furthermore, the reset mechanism includes two sets of fixing rods. The fixing rods are installed at the end of the slider away from the fixing sleeve. The fixing rods are slidably connected inside the fixing plate. A spring is sleeved on the outer end of the fixing rod. The side of the spring closest to the fixing sleeve is installed on the outer surface of the fixing plate.

[0010] Furthermore, two sets of handles are installed on the front of the fixing plate, and the front of the two sets of handles are located on the front side of the control panel.

[0011] Furthermore, the support mechanism includes a clamping plate, which is clamped to the lower end of the fixed plate. An electric telescopic rod is installed at the lower end of the clamping plate, and a base plate is installed at the end of the electric telescopic rod away from the clamping plate.

[0012] Furthermore, two sets of vacuum suction cups are installed inside the base plate.

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

[0014] 1. This utility model uses a rotating annular sleeve to push two sets of sliders to slide inside two sets of slots on a fixed sleeve. The positions of the two sets of arc-shaped limiting blocks are adjusted and moved onto the moving path of the outer end nut of the anchor rod. This ensures that when the hydraulic cylinder is activated to pull the sliding plate to test the concrete, the front of the two sets of arc-shaped limiting blocks abuts against the back of the outer end nut of the anchor rod. This allows the hydraulic cylinder to pull anchor rods of various outer diameters during activation, thereby improving the applicability of the device and enhancing its practicality.

[0015] 2. This utility model uses an electric telescopic rod to push the clamping plate upwards, clamping it to the bottom of the fixed plate. This allows the subsequent support mechanism to support the fixed plate, thus minimizing the risk of the device falling and being damaged after being pulled out. Consequently, the device does not require prolonged manual support during use, thereby improving its practicality. Attached Figure Description

[0025] like Figures 1 to 4As shown, a concrete pull-out apparatus for building safety assessment includes a fixed plate 1. A control panel 2 is mounted on the front of the fixed plate 1. A hydraulic cylinder 4 is mounted on the inner wall of the front of the fixed plate 1. A tension detector 5 is mounted on the output end of the hydraulic cylinder 4. A sliding plate 6 is mounted on the end of the tension detector 5 away from the hydraulic cylinder 4. A clamping mechanism 10 for clamping multiple sets of anchor rods is mounted on the side of the sliding plate 6 away from the tension detector 5. A support mechanism 8 for supporting the use position of the fixed plate 1 is engaged at the lower end of the fixed plate 1. A repositioning mechanism for the internal equipment of the clamping mechanism 10 is mounted on the outer end of the clamping mechanism 10. The reset mechanism 7 has slots on both the left and right inner walls of the fixing plate 1, and the sliding plate 6 is slidably connected to the two sets of slots in the fixing plate 1. Specifically, by rotating the clamping mechanism 10, the position of the clamping mechanism 10 is adjusted and moved to the rear side of the nut at the outer end of the anchor rod, so that when the hydraulic cylinder 4 is started to pull the anchor rod, the clamping mechanism 10 fits against the back of the nut at the outer end of the anchor rod. This allows the hydraulic cylinder 4 to pull anchor rods of various outer diameters during the start-up process, thereby improving the applicability of the device and thus enhancing its practicality.

[0026] like Figures 1 to 3 As shown, the clamping mechanism 10 includes a fixed sleeve 1001, which is installed on the side of the slide plate 6 away from the tension detector 5. Slider blocks 1003 are slidably connected to the interior of both the left and right sides of the fixed sleeve 1001. An annular sleeve 1002 is rotatably connected to the outer end of the fixed sleeve 1001. External threads are formed on the outer surface of the fixed sleeve 1001, and the annular sleeve 1002 is threaded into the external threads of the fixed sleeve 1001. Slots are formed on both the left and right sides of the fixed sleeve 1001, and two sets of sliders 1003 are slidably connected to the two sets of slots in the fixed sleeve 1001. The sliders 1003 are located on the side away from the inner wall of the fixed plate 1. An arc-shaped limiting block 1004 is installed. Specifically, by rotating the annular sleeve 1002, two sets of sliders 1003 are pushed to slide inside the two sets of slots of the fixed sleeve 1001. The positions of the two sets of arc-shaped limiting blocks 1004 are adjusted and moved to the moving path of the outer end nut of the anchor rod. This ensures that when the hydraulic cylinder 4 is activated to pull the slide plate 6 to test the concrete, the front of the two sets of arc-shaped limiting blocks 1004 abuts against the back of the outer end nut of the anchor rod. This allows the hydraulic cylinder 4 to pull anchor rods of various outer diameters during the activation process, thereby improving the applicability of the device and thus enhancing its practicality.

[0027] like Figures 1 to 4As shown, the reset mechanism 7 includes two sets of fixing rods 702. The fixing rods 702 are installed at the end of the slider 1003 away from the fixing sleeve 1001. The fixing rods 702 are slidably connected inside the fixing plate 1. A spring 701 is sleeved on the outer end of the fixing rod 702. The side of the spring 701 closest to the fixing sleeve 1001 is installed on the outer surface of the fixing plate 1. A fixing ring 703 is installed on the outer end of the fixing rod 702. The side of the spring 701 away from the fixing sleeve 1001 is installed on the side of the fixing ring 703 closest to the fixing sleeve 1001. Through holes are provided on both the left and right sides of the fixing plate 1. 02 are slidably connected to the two sets of through holes in the fixed plate 1 respectively; specifically, the spring 701 has good elastic potential energy, so that when the subsequent slider 1003 moves inward, it drives the fixed ring 703 to compress the length of the spring 701. In turn, when the subsequent annular sleeve 1002 is reset, the spring 701 pushes the fixed ring 703 to pull the spring 701 and drive the slider 1003 to reset. This eliminates the need for the subsequent staff to manually reset the positions of the two sets of arc-shaped limit blocks 1004, thus reducing the time and labor required for the subsequent staff to operate the device.

[0028] like Figure 1 and Figure 2 As shown, two sets of handles 3 are installed on the front of the fixing plate 1, and the front of the two sets of handles 3 is located in front of the control panel 2. Specifically, by positioning the front of the two sets of handles 3 in front of the control panel 2, the two sets of handles 3 restrict the movement of the control panel 2 during use, thereby minimizing the risk of the control panel 2 being damaged by collisions with foreign objects during the handling, moving, or tilting of the device.

[0029] like Figure 1 and Figure 2 As shown, the support mechanism 8 includes a clamping plate 801, which is clamped to the lower end of the fixed plate 1. An electric telescopic rod 802 is installed at the lower end of the clamping plate 801, and a base plate 803 is installed at the end of the electric telescopic rod 802 away from the clamping plate 801. Specifically, by activating the electric telescopic rod 802, the clamping plate 801 is pushed upward to clamp the clamping plate 801 to the bottom end of the fixed plate 1, so that the subsequent support mechanism 8 supports the fixed plate 1, thereby minimizing the risk of the device falling after being pulled out and causing damage to the device. This also eliminates the need for prolonged manual support during subsequent use, thus improving the practicality of the device.

[0030] like Figure 1 and Figure 2As shown, two sets of vacuum suction cups 9 are installed inside the base plate 803. Two sets of grooves are formed on the upper surface of the base plate 803, and the two sets of vacuum suction cups 9 are respectively inserted into the two sets of grooves of the base plate 803. Specifically, by pushing the two sets of vacuum suction cups 9, the lower surfaces of the two sets of vacuum suction cups 9 are pressed against the ground. Then, by rotating the two sets of vacuum suction cups 9, the lower surfaces of the two sets of vacuum suction cups 9 are adsorbed onto the ground. This allows the two sets of vacuum suction cups 9 to restrict the position of the support mechanism 8 on the ground, thereby minimizing the movement of the support mechanism 8 during use and thus improving the stability of the support mechanism 8 during use.

[0031] In summary: By rotating the annular sleeve 1002, the two sets of sliders 1003 are pushed to slide inside the two sets of slots of the fixed sleeve 1001, and the positions of the two sets of arc-shaped limiting blocks 1004 are adjusted and moved to the moving path of the outer end nut of the anchor rod. This ensures that when the hydraulic cylinder 4 is activated to pull the slide plate 6 to test the concrete, the front of the two sets of arc-shaped limiting blocks 1004 abuts against the back of the outer end nut of the anchor rod. This allows the hydraulic cylinder 4 to pull anchor rods of various outer diameters during activation. The spring 701 has good elastic potential energy, which causes the fixed ring 703 to compress the length of the spring 701 as the slider 1003 moves inward. This causes the spring 701 to push the fixed ring 703 to pull the spring 701 and drive the slider 1003 to reset during the resetting process of the annular sleeve 1002.

[0032] Simultaneously, by activating the electric telescopic rod 802, the clamping plate 801 is moved upward, clamping the clamping plate 801 to the bottom end of the fixed plate 1, so that the subsequent support mechanism 8 supports the fixed plate 1, thereby minimizing the risk of the device falling and being damaged after being pulled out; by pushing the two sets of vacuum suction cups 9, the lower surfaces of the two sets of vacuum suction cups 9 are pressed against the ground, and then by rotating the two sets of vacuum suction cups 9, the lower surfaces of the two sets of vacuum suction cups 9 are adsorbed onto the ground, so that the subsequent two sets of vacuum suction cups 9 restrict the use position of the support mechanism 8 on the ground.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
