Description

Technical Field

[0001] The present invention relates to the technical field of anchor bolt tension tests, and specifically relates to an anchor bolt tension test device. Background Art

[0002] The fan foundation is used for the fixation of a wind power generation unit. Together with the tower barrel of the wind power generation unit, it erects the wind turbine at an altitude of 60m to 160m and bears the alternating loads in all 360° directions. Due to the characteristics of large eccentricity, large load, and poor distribution uniformity of this load, the fan foundation bears a very complex load environment. In recent years, the single-unit capacity of domestic wind turbines has developed towards large-scale, and the load of the fan foundation has also increased accordingly. The prestressed fan foundation has replaced the traditional gravity-expanded fan foundation and become the mainstream fan foundation form in China.

[0003] The anchor bolt assembly is the core component of the prestressed fan foundation. Generally, it has a structure with threads at both ends and a smooth rod in the middle, and its length is 4m to 12m. The cage structure composed of wind power anchor bolts is cast together with reinforced concrete. The prestressed tensioning technology is adopted to enable the anchor bolt assembly to evenly transfer the fan foundation load and bear various complex load conditions of the wind power generation unit. Before leaving the factory, the anchor bolts should undergo 100% tension detection. Anchor bolt tensioning refers to loading the anchor bolt assembly to the specified load and maintaining this load for a period of time to test the tension performance of the finished anchor bolts and avoid quality hazards caused by local processing, material defects, etc.

[0004] The specific steps of the anchor bolt tension test method are as follows: First, apply a tensile force of 10% of the nominal specified plastic extension strength Rp0.2 of the anchor bolt, check whether each component is normal, then slowly load to a tensile force of k times the nominal plastic extension strength Rp0.2 of the anchor bolt (k generally should not be less than 0.7), maintain the load, then unload to a tensile force of 10% of the nominal specified plastic extension strength Rp0.2 of the anchor bolt, and finally completely unload.

[0005] The anchor bolt tension test is carried out through a tensioning main machine, and the tensioning main machine is an existing product, such as Figures 1 to 5As shown in the figure, movable clamps 17 and fixed clamps 21 are respectively arranged at the left and right ends of the tensioning station 25 of the tensioning main machine 11. The fixed clamp 21 is fixedly connected to the tensioning main machine 11, and the movable clamp 17 can move in the left - right direction. Placing cavities 30 with openings facing upward are provided on both the movable clamp 17 and the fixed clamp 21. U - shaped grooves 31 penetrating left - right are provided on the opposing side walls of the two placing cavities 30. The two U - shaped grooves 31 are aligned left - right. The cross - section of the U - shaped groove 31 is smaller than that of the placing cavity 30. After the two ends of the anchor rod 33 are placed in the U - shaped grooves 31 at the left and right ends, the nuts 34 on the anchor rod 33 are respectively clamped into the placing cavities 30 and are in a blocking fit with the groove walls of the corresponding U - shaped grooves 31 in the left - right direction. The side of the movable clamp 17 away from the fixed clamp is fixedly connected to the piston rod of the hydraulic cylinder 20. The hydraulic cylinder 20 drives the movable clamp 17 to move outward through the piston rod to tension the anchor rod 33.

[0006] In traditional wind power anchor rod tensioning tests, the anchor rod is manually fed into and out of the tensioning test equipment, resulting in a relatively high labor intensity, a long time for the anchor rod to be fed into and out of the tensioning test equipment, and a low tensioning efficiency. Summary of the Invention

[0007] The purpose of the present invention is to provide an anchor rod tensioning test equipment to solve the technical problems of relatively high labor intensity and low tensioning efficiency when manually feeding and discharging the anchor rod into and out of the tensioning test equipment in the prior art.

[0008] To achieve the above - mentioned purpose, the technical solution of the anchor rod tensioning test equipment of the present invention is as follows:

[0009] An anchor rod tensioning test equipment includes a tensioning main machine. The tensioning main machine has a tensioning station for tensioning the anchor rod, and the length direction of the tensioning main machine is defined as the left - right direction; a feeding unit for storing the anchor rods to be tensioned and a discharging unit for storing the tensioned anchor rods are provided beside the tensioning main machine; the anchor rod tensioning test equipment further includes a transfer mechanism. The transfer mechanism includes a transfer frame and a rod - taking frame. The rod - taking frame can reciprocate on the transfer frame in the front - back direction and the up - down direction. A rod - taking structure is provided on the rod - taking frame for removing the anchor rods to be tensioned on the feeding unit and transferring them to the tensioning station and for transferring the tensioned anchor rods at the tensioning station to the discharging unit.

[0010] The beneficial effects are as follows: In the anchor rod tensioning test equipment of the present invention, the rod - taking frame can reciprocate on the transfer frame in the front - back direction and the up - down direction, so that the rod - taking structure on the rod - taking frame can remove the anchor rods to be tensioned on the feeding unit and transfer them to the tensioning station of the tensioning main machine, thereby tensioning the anchor rods at the tensioning station. Also, the rod - taking structure can transfer the tensioned anchor rods at the tensioning station to the discharging unit. Therefore, the rod - taking structure functions as a manipulator, and the transfer mechanism can realize automatically feeding and discharging the anchor rod into and out of the tensioning main machine, replacing manual handling operations, significantly reducing the labor intensity, and improving the tensioning efficiency.

[0011] Further improvement: The feeding unit includes a feeding rack and a feeding mechanism. The feeding mechanism is used to convey the anchor rods to be tensioned on the feeding rack to the rod-taking structure.

[0012] Beneficial effect: With such a design, the single anchor rod on the feeding rack is conveyed to the rod-taking structure by the feeding mechanism, so as to reduce the stroke of the rod-taking structure, reduce the volume of the transfer rack, and avoid interference between the transfer rack and the feeding unit.

[0013] Further improvement: The feeding mechanism includes a feeding telescopic cylinder and a feeding guide plate. One end of the feeding guide plate is hinged on the side wall of the tensioning main machine. The feeding telescopic cylinder is used to drive the feeding guide plate to swing up and down, so that the feeding guide plate guides the anchor rods to be tensioned to the rod-taking structure.

[0014] Beneficial effect: Compared with conveying the anchor rod through the horizontal and vertical movements of the feeding mechanism, with such a design, the anchor rod is conveyed by the up-and-down swing of the feeding guide plate, and the structure is simple and easy to implement.

[0015] Further improvement: The rod-taking structure is a support column, and a positioning groove for placing the anchor rod is provided on the support column.

[0016] Beneficial effect: With such a design, the rod-taking structure limits the anchor rod through the positioning groove, avoiding the anchor rod from falling off the support column.

[0017] Further improvement: The feeding unit and the discharging unit are located on the same side of the tensioning main machine.

[0018] Beneficial effect: With such a design, the rod-taking structure only needs to reciprocate on the same side of the entire tensioning main machine, without changing the movement area and movement direction, reducing the operation difficulty of the rod-taking structure and simplifying the structure of the transfer mechanism.

[0019] Further improvement: The transfer rack includes a vertical frame, a sliding frame and a cantilever extending in the front-rear direction. The vertical frame is fixed on the tensioning main machine, and the vertical frame and the feeding unit are respectively located on both sides of the tensioning station; at least two cantilevers are distributed at intervals in the left-right direction, the sliding frame reciprocates on the cantilever in the front-rear direction, and the rod-taking frame reciprocates on the sliding frame in the up-down direction.

[0020] Beneficial effect: Compared with the vertical frame being fixed beside the tensioning main machine, with such a design, the cantilever avoids the anchor rod, making the volume of the transfer mechanism smaller and the weight lighter.

[0021] Further improvement: The discharging unit includes a discharging rack. A motor and a plurality of grooved wheels distributed at intervals in the left-right direction are provided on the discharging rack. The grooved wheels are used to jointly support the tensioned anchor rods, and the motor is used to drive the grooved wheels to rotate to drive the tensioned anchor rods to be transported out in the left-right direction.

[0022] The beneficial effect is that with such a design, the groove wheel has a front and rear limiting effect on the anchor rod, thereby preventing the anchor rod from deflecting during transportation and interfering with other parts.

[0023] As a further improvement, the unloading unit also includes a unloading guide plate, one end of which is hinged on the side wall of the tensioning main machine. When the rod taking structure is lower than the unloading guide plate, the unloading guide plate is used to guide the tensioned anchor rods on the rod taking structure to be transferred to the groove wheel of the unloading rack.

[0024] The beneficial effect is: with such a design, the unloading guide plate can transfer the anchor rods on the rod taking structure to the unloading rack, and the rod taking structure does not need to move downward to the unloading rack, thereby reducing the movement stroke of the rod taking structure and simplifying the structure of the transfer mechanism.

[0025] As a further improvement, the material unloading unit also includes at least two material receiving mechanisms, all of which are spaced apart in the left-right direction, and the material receiving mechanism includes a material receiving support and a material receiving telescopic cylinder, which drives the material receiving support to reciprocate up and down. When the material receiving support is higher than the groove wheel, it is used to support the anchor rod that falls from the material unloading guide plate, and when the material receiving support is lower than the groove wheel, it is used to make the supported anchor rod fall onto the groove wheel.

[0026] The beneficial effect is: with this design, the anchor rod is first received by the upwardly moving material receiving support, and then the anchor rod is dropped onto the material unloading rack by the downwardly moving material receiving support, thereby preventing the anchor rod that freely rolls down from the material unloading guide plate from colliding with the groove wheel and then falling off the groove wheel.

[0027] As a further improvement, the material receiving support is a material receiving column, and a limit plate is provided on the end of the material receiving column away from the tensioning main machine, and the limit plate is used to cooperate with the anchor rod falling from the material unloading guide plate.

[0028] The beneficial effect is that: with such a design, since the anchor rod has a certain horizontal speed when falling from the material unloading guide plate, the stopping cooperation between the limit plate and the anchor rod facilitates the anchor rod to fall onto the material receiving support.

[0049] Embodiment 1 of the anchor rod tension test equipment provided in the present invention:

[0050] As Figure 6 and Figure 7 shown, the anchor rod tension test equipment includes a tensioning main machine 11 with a tensioning station 25. The tensioning main machine 11 tensions the anchor rod 33 at the tensioning station 25. A loading unit and a discharging unit 14 are arranged beside the tensioning main machine 11, and a transfer mechanism 16 is arranged above the tensioning main machine 11. The loading unit is used to store the anchor rods 33 to be tensioned, the discharging unit 14 is used to store and transport the tensioned anchor rods 33, and the transfer mechanism 16 can transfer the single anchor rod 33 to be tensioned on the loading unit to the tension test area so that the anchor rod 33 can carry out subsequent tension tests. The transfer mechanism 16 can also transfer the anchor rod 33 after the tension test to the discharging unit 14 so that the discharging unit 14 can convey the tensioned anchor rod 33 to the next process. Wherein, the length direction of the anchor rod 33 is defined as the left-right direction.

[0051] As Figure 8 shown, the loading unit includes a loading rack 12 and a loading mechanism 13. Two loading racks 12 are arranged at intervals along the left-right direction, and the loading rack 12 can store the anchor rods 33 to be tensioned. The loading rack 12 is a frame structure as a whole. Two loading support rods 22 are arranged at the top of the loading rack 12. The loading support rods 22 all extend along the front-back direction and are distributed at intervals along the left-right direction. The top surfaces of all the loading support rods 22 are in the same plane to form the loading support surface 23 of the loading rack 12. The loading support rods 22 extend obliquely downward from front to back so that the loading support surface 23 extends obliquely downward from front to back, facilitating the anchor rod 33 to roll backward under the action of gravity.

[0052] A stop projection 24 is provided at the rear end of each loading support rod 22. The stop projection 24 can contact and stop the corresponding anchor rod 33, so that the anchor rods 33 can be arranged in a single layer along the front-back direction on the loading support surface 23.

[0053] As Figures 1 to 5 shown, the tensioning main machine 11 includes a frame. The frame is a horizontal frame structure as a whole. The frame includes feet 27, a front frame 18 and a rear frame 19. The feet 27, the front frame 18 and the rear frame 19 are all made of H-shaped steel. The front frame 18 and the rear frame 19 are arranged at intervals along the front-back direction. The feet 27 extend along the front-back direction and are provided with a plurality of them at intervals in the left-right direction. The feet 27 are welded and fixed to the bottoms of the front frame 18 and the rear frame 19 to support the entire frame.

[0054] On the left side of the frame, a hydraulic cylinder mounting frame 28 is fixedly welded. The hydraulic cylinder 20 is fixedly connected to the hydraulic cylinder mounting frame 28 by bolts. Moreover, the piston rod of the hydraulic cylinder 20 extends into the front and rear intervals between the front frame 18 and the rear frame 19.

[0055] Jigs are placed at both the left and right ends of the frame, namely a movable jig 17 and a fixed jig 21 respectively. Four support wheels 32 arranged in the front-rear and left-right directions are installed at the bottom of both jigs. The support wheels 32 can move left and right within the front and rear intervals between the front frame 18 and the rear frame 19. Placing cavities 30 with upward openings are provided on both the movable jig 17 and the fixed jig 21. U-shaped grooves 31 penetrating left and right are provided on the facing side walls of the two placing cavities 30. The two U-shaped grooves 31 are aligned left and right. The cross-section of the U-shaped groove 31 is smaller than that of the placing cavity 30. The area between the movable jig 17 and the fixed jig 21 forms a tensioning station 25. During the tensioning test, nuts 34 and gaskets are manually installed at both ends of the anchor rod 33, and both ends of the anchor rod 33 are respectively clamped in the movable jig 17 and the fixed jig 21. Among them, the rod part of the anchor rod 33 is clamped in the U-shaped groove 31, and the nuts 34 and gaskets are clamped in the placing cavity 30. The nuts 34 are in stop fit with the groove walls of the U-shaped groove 31 in the left-right direction to tension the anchor rod 33 by tensioning the movable jig 17.

[0056] Two insertion pin holes are provided at the top of the fixed jig 21, which are distributed at intervals front and rear. Connecting holes corresponding to the insertion pin holes on the fixed jig 21 are provided on the front frame 18 and the rear frame 19. The fixed jig 21 is fixed to the front frame 18 and the rear frame 19 by pin shafts. Moreover, multiple groups of connecting holes are distributed at intervals in the left-right direction to be able to adjust the position of the fixed jig 21 according to the length of the anchor rod 33.

[0057] The hydraulic cylinder 20 provides the pulling force for the tensioning test of the anchor rod 33. An insertion hole extending in the left-right direction is provided at the left end of the movable jig 17. A radially penetrating pin hole is provided on the side wall of the insertion hole. A corresponding pin hole is provided at the end of the piston rod of the hydraulic cylinder 20. The piston rod is inserted into the connecting hole and connected by a pin shaft. During the tensioning test, the fixed jig 21 remains stationary, and the hydraulic cylinder 20 drives the movable jig 17 to move horizontally to the left through the piston rod, thereby tensioning the anchor rod 33 that is in stop fit with the movable jig 17.

[0058] As Figure 8 and Figure 9As shown in the figure, the feeding mechanism 13 is mounted on the front frame 18 of the tensioning main machine 11 through a connecting plate 37. A plurality of feeding mechanisms 13 are arranged at intervals in the left-right direction and are used to convey the anchor bolts 33 to the transfer mechanism 16 one by one. The feeding mechanism 13 includes a feeding guide plate 35 and a feeding cylinder 36. The feeding cylinder 36 constitutes a feeding telescopic cylinder. One end of the feeding guide plate 35 is hinged to the connecting plate 37. A hinge seat is fixed on the connecting plate 37. Two hinge ear plates are arranged on the hinge seat at intervals in the left-right direction. The hinged ends of the feeding guide plate 35 and the hinge ear plates are both provided with hinge holes penetrating through in the left-right direction. A pin shaft is inserted into the hinge holes to hinge the feeding guide plate 35 to the hinge seat. A cylinder mounting seat is fixed on the connecting plate 37 below the hinge seat. The feeding cylinder 36 is fixed to the cylinder mounting seat by bolts. The upper end of the piston rod of the feeding cylinder 36 is hinged to the bottom of the feeding guide plate 35 through a hinge, so as to drive the feeding guide plate 35 to swing up and down around the hinge point through the telescopic piston rod. When the piston rods of all the feeding cylinders 36 extend synchronously, the feeding guide plate 35 rotates upward around the hinge point to convey the single anchor bolt 33 that contacts and stops against the stop protrusion 24 on the feeding rack 12 to the transfer mechanism 16. When the piston rods of the feeding cylinders 36 contract synchronously, the feeding guide plate 35 rotates downward around the hinge point until it is below the feeding support surface 23 of the feeding rack 12. In this embodiment, the feeding cylinder 36 constitutes a feeding telescopic cylinder.

[0059] As Figure 10 shown, the transfer mechanism 16 can send the anchor bolts 33 into and out of the tensioning station 25 of the tensioning main machine 11 one by one. The transfer mechanism 16 includes a transfer rack and a rod picking rack. The transfer rack includes a sliding rack, a vertical rack 38, and two overhanging arms 39 arranged at intervals in the left-right direction. The vertical rack 38 is fixed on the rear frame 19 of the tensioning main machine 11. The overhanging arms 39 are fixed to the side of the vertical rack 38 close to the feeding rack 12 in the front-rear overhanging manner. The overhanging arms 39 have a certain distance from the top surface of the tensioning main machine 11 in the height direction and extend forward beyond the front frame 18.

[0060] The sliding rack reciprocates on the overhanging arms 39 in the front-rear direction, and the rod picking rack reciprocates on the sliding rack in the up-down direction. The sliding rack includes a sliding mounting seat. Horizontal moving sliders 42 are respectively arranged at both ends of the sliding mounting seat. Horizontal guide rails 40 extending in the front-rear direction are arranged at the upper ends of the two overhanging arms 39. The two horizontal moving sliders 42 are respectively slidably assembled on the corresponding horizontal guide rails 40. A horizontal telescopic cylinder 49 is arranged behind the slider mounting seat 41. The horizontal telescopic cylinder 49 is fixed to the vertical rack 38 through a fixed seat. The horizontal telescopic cylinder 49 drives the piston rod to extend and contract in the front-rear direction. The piston rod of the horizontal telescopic cylinder 49 is fixed to the rear end of the slider mounting seat 41, so as to drive the horizontal moving slider 42 to move forward and backward through the telescopic movement of the piston rod, and further drive the rod picking rack to move forward and backward.

[0061] The rod taking frame is provided with a rod taking structure 45, and the rod taking structure 45 can support the anchor rod 33. The rod taking frame includes a rod taking mounting seat 43 extending in the left-right direction. The rod taking mounting seat 43 is located below the cantilever 39. Vertical rods 47 are respectively provided at the left and right ends of the upper end of the rod taking mounting seat 43. Vertical moving sliders 46 are respectively fixed at the left and right ends of the slider mounting seat 41. Each vertical moving slider 46 is provided with a through hole in the up-down direction, and the vertical rod 47 passes upward through the through hole. A rod taking connecting plate 44 is fixed on the front side of the rod taking mounting seat 43. Two rod taking structures 45 are arranged on the rod taking connecting plate 44 perpendicular to each other in the front-back direction. The two rod taking structures 45 and the feeding guiding plate 35 are distributed staggeredly in the left-right direction. In this embodiment, the rod taking structure 45 is a support column, and a V-shaped positioning groove is provided on the upper surface of the support column. When the support column supports the anchor rod 33, the anchor rod 33 is placed in the positioning groove.

[0062] A vertical telescopic cylinder 48 is fixed at the top end of the slider mounting seat 41. A vertically through avoidance hole is provided on the slider mounting seat 41. The piston rod of the vertical telescopic cylinder 48 passes downward through one end of the avoidance hole and is fixed on the rod taking mounting seat 43, so as to drive the rod taking structure 45 to move up and down through the up and down telescopic movement of the piston rod of the vertical telescopic cylinder 48.

[0063] The telescopic movements of the horizontal telescopic cylinder 49 and the vertical telescopic cylinder 48 drive the rod taking structure 45 to transfer the anchor rod 33 to be tensioned on the feeding mechanism 13 to the tensioning station 25 and transfer the tensioned anchor rod 33 to the blanking unit 14.

[0064] As Figures 11 to 13 shown, the blanking unit 14 and the feeding unit are both located on the same side of the tensioning main machine 11. The blanking unit 14 includes a blanking frame 54, a material receiving mechanism 15 and a blanking guiding plate. The blanking frame 54 is located below the feeding mechanism 13. The blanking guiding plate is hinged on the side wall of the tensioning main machine 11. When the rod taking structure 45 is lower than the blanking guiding plate, the blanking guiding plate guides the anchor rod 33 on the rod taking structure 45 to fall on the blanking frame 54, so that the anchor rod 33 rolls freely along the blanking guiding plate. In this embodiment, the blanking guiding plate is the feeding guiding plate 35 of the feeding mechanism 13.

[0065] A plurality of V-shaped sheaves 55 are arranged at intervals along the left-right direction above the unloading rack 54. All the sheaves 55 cooperate to position and support a single anchor rod 33 on the material receiving support member 52 that moves downward. A motor is installed at the leftmost end of the unloading rack 54. A main sprocket is installed on the output shaft of the motor. The rotation center axis of each sheave 55 extends along the front-back direction. A slave sprocket 26 is installed at the front end of each sheave 55. A slave sprocket 26 is arranged between any two adjacent sheaves 55 below the unloading rack 54. The main sprocket and the slave sprocket 26 are connected by a chain 29. The motor drives the sheave 55 to rotate through the sprocket and the chain 29, thereby driving the anchor rod 33 to move in the left-right direction. Moreover, the V-shaped sheave 55 can limit the front and back positions of the anchor rod 33 to prevent the anchor rod 33 from shifting during movement.

[0066] There are two receiving mechanisms 15, which are respectively installed at the left and right ends of the material discharging rack 54. The receiving mechanisms 15 can receive the anchor rods 33 that roll freely from the material loading guide plate 35. The receiving mechanism 15 includes a receiving cylinder 50 and a receiving support 52. In this embodiment, the receiving support 52 is a receiving column, and a V-shaped receiving groove is provided on the upper surface of the receiving column. The receiving cylinder 50 is installed on the upper end of the material discharging rack 54 through the receiving cylinder mounting seat 51. The receiving cylinder 50 drives the piston rod to extend and retract in the up and down directions to drive the receiving support 52 to reciprocate up and down. The receiving support 52 is fixed to the piston rod of the receiving cylinder 50 through the L-shaped mounting plate 53. The receiving support 52 is vertically fixed to the vertical plate of the L-shaped mounting plate 53 in the front and back directions, and the horizontal plate of the L-shaped mounting plate 53 is fixed to the upper end of the piston rod of the receiving cylinder 50. In this embodiment, the receiving cylinder 50 constitutes a receiving telescopic cylinder.

[0067] The receiving support 52 is lower than the swing end of the material feeding guide plate 35. When the receiving cylinder 50 drives the receiving support 52 to be higher than the groove wheel 55, the receiving support 52 can support the anchor rod 33 that rolls freely from the material feeding guide plate 35, and the vertical plate of the L-shaped mounting plate 53 can stop the anchor rod 33. When the receiving cylinder 50 drives the receiving support 52 to be lower than the groove wheel 55, the anchor rod 33 supported on the receiving support 52 can fall on the groove wheel 55. After the groove wheel 55 transports the anchor rod 33 to the next step, the receiving cylinder 50 drives the receiving support 52 to move upward, waiting to receive the next tensioned anchor rod 33. In this embodiment, the vertical plate of the L-shaped mounting plate 53 constitutes a limit plate that cooperates with the anchor rod 33 to stop.

[0068] When the anchor bolt tension test equipment is working, the rod-taking structure 45 is located below the feeding guiding plate 35. The feeding telescopic cylinder drives the feeding guiding plate 35 to swing upward. A single anchor bolt 33 on the feeding rack 12 falls onto the feeding guiding plate 35. The vertical telescopic cylinder 48 contracts to drive the rod-taking structure 45 to move upward to a height higher than the feeding guiding plate 35, so that the anchor bolt 33 falls into the V-shaped groove of the rod-taking structure 45. After the anchor bolt 33 is higher than the upper surface of the tensioning main machine 11 by a certain height, nuts 34 and gaskets are manually installed at both ends of the anchor bolt 33. The horizontal telescopic cylinder 49 contracts to drive the anchor bolt 33 to move backward, so that the anchor bolt 33 moves above the tensioning station 25 of the tensioning main machine 11. The vertical telescopic cylinder 48 extends to send the anchor bolt 33 into the U-shaped groove 31 on the movable clamp 17 and the fixed clamp 21. The hydraulic cylinder 20 tensions the anchor bolt 33. After the tension test of the anchor bolt 33 is completed, the vertical telescopic cylinder 48 contracts to drive the anchor bolt 33 to move upward. After the anchor bolt 33 is higher than the upper surface of the tensioning main machine 11 by a certain height, the horizontal telescopic cylinder 49 extends to drive the anchor bolt 33 to move horizontally forward. The anchor bolt 33 moves above the feeding mechanism 13. The nuts 34 and gaskets at both ends of the anchor bolt 33 are manually disassembled. The vertical telescopic cylinder 48 extends to drive the anchor bolt 33 to move downward until the anchor bolt 33 falls onto the feeding guiding plate 35 of the feeding mechanism 13. The anchor bolt 33 freely rolls along the feeding guiding plate 35 and falls onto the material receiving support 52. The material receiving cylinder 50 contracts, and the material receiving support 52 is lower than the grooved wheel 55. The anchor bolt 33 falls onto the grooved wheel 55, and the grooved wheel 55 transports the anchor bolt 33 out.

[0069] In the anchor bolt tension test equipment of the present invention, the rod-taking rack can reciprocate in the front-back direction and the up-down direction on the transfer rack. The rod-taking structure 45 functions as a manipulator, which can transport a single anchor bolt 33 to be tensioned on the feeding rack 12 to the tensioning station 25 of the tensioning main machine 11, and can also transport the tensioned anchor bolt 33 to the blanking unit 14, so that the tensioned anchor bolt 33 is transported out through the blanking unit 14, so as to automatically feed and discharge the anchor bolt 33 into and out of the tensioning station 25 of the tensioning main machine 11, replacing manual handling operations, significantly reducing labor intensity and improving tensioning efficiency.
