[0033] In the related technology, since rock climbing is an extreme sport with certain risks, it is very necessary to ensure the safety of the rock climbing site. Therefore, it is very important to inspect the basic conditions, facilities and equipment of the rock climbing site. Among them, the rock climbing fulcrum is an important accessory of rock climbing facilities such as rock climbing walls. Its manufacturing materials and processes are similar to those of rock plates. It has different shapes and is generally fixed to the rock plate with stainless steel bolts. It can be used as a handhold and foothold for rock climbing enthusiasts when climbing.

[0034] In the related art, the structural integrity of a climbing fulcrum is generally tested by the following experimental method, which can reflect the magnitude of the structural force resistance of the climbing fulcrum. For example, the climbing fulcrum is fixed to the surface of a rigid structure such as a sample mounting plate by fixing screws, and then a target thrust value, such as 2.4KN, is applied to the climbing fulcrum through a force-applying assembly for 1 minute, so as to detect and evaluate whether the climbing fulcrum meets the standard requirements based on whether it is intact under the corresponding thrust.

[0035] In order to ensure the safety and reliability of rock climbing supports during use, the current domestic testing is mainly based on EN 12572-3:2017 (E) "Artificial climbing structures Part 3: Safety requirements and test methods for rock climbing supports". However, this standard only gives the safety requirements for rock climbing supports and the above-mentioned test methods, and does not provide a technical solution for specific equipment for testing the structural integrity of rock climbing supports.

[0036] However, since the installation position of the climbing fulcrum is usually fixed, only the climbing fulcrum of a single specification can be tested. When the structural integrity of the climbing fulcrums of different specifications is tested, it is difficult to ensure the accuracy of the test results.

[0037] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a detection device for testing the structural integrity of a rock climbing fulcrum.

[0038] like Figure 1As shown, an embodiment of the utility model provides a detection device for testing the structural integrity of a rock climbing fulcrum, comprising a bracket 2, a mounting plate 1, a force-applying assembly 3, a force sensor 4 and a pressure element 5, wherein the force-applying assembly 3 is mounted on the bracket 2, and a plurality of strip grooves 11 are provided on the mounting plate 1, and the plurality of strip grooves 11 are spaced apart along a first direction, and the strip grooves 11 are used for sliding connection with a rock climbing fulcrum 8; the top end of the mounting plate 1 is movably connected with the bracket 2, and the mounting plate 1 is used for rotating relative to the bracket 2; the force-applying assembly 3 is connected with the force sensor 4, and the force sensor 4 is connected with the pressure element 5, and the force-applying assembly 3 is used for driving the pressure element 5 to move along a second direction to abut against or away from the rock climbing fulcrum 8; the second direction is perpendicular to the first direction.

[0039] Specifically, the first direction is Figure 1 The coordinate system is parallel to the X-axis, and the second direction is Figure 1 The Y-axis direction in the coordinate system is parallel, so the second direction is perpendicular to the first direction. The bracket 2 can be installed on the ground or other platforms, and the bracket 2 provides an installation basis for the force-applying component 3 and the mounting plate 1. Among them, the force-applying component 3 can be installed on the upper part of the bracket 2, the central axis of the force sensor 4 and the pressure element 5 can be parallel to the ground, the mounting plate 1 can be rotated within a certain angle relative to the bracket 2, and the rock climbing fulcrum 8 can be detachably installed on the mounting plate 1. By rotating the mounting plate 1, the angle of the part to be tested of the rock climbing fulcrum 8 on the mounting plate 1 can be adjusted. When the part to be tested of the rock climbing fulcrum 8 is perpendicular to the central axis of the pressure element 5, the detection conditions for applying the target thrust to the rock climbing fulcrum 8 are met.

[0040] The force-applying assembly 3 provides the pressure element 5 with a thrust applied to the rock climbing fulcrum 8. The pressure element 5 may be a rubber head, which has a certain degree of flexibility to avoid cracking or other damage during the process of bearing the thrust. The force sensor 4 is used to detect the thrust value of the pressure element 5 acting on the rock climbing fulcrum to determine whether the target thrust value is reached.

[0041] The number of the strip grooves 11 on the mounting plate 1 is at least two, as long as at least two strip grooves 11 are spaced apart along the first direction and can achieve the purpose of adjusting the position of the climbing fulcrum 8 in the first direction.

[0042] In this embodiment, since the rock climbing fulcrum 8 is usually of an irregular shape, before the structural integrity test of the rock climbing fulcrum 8 of the current specification and shape, such as the shape, is performed, the position and angle of the rock climbing fulcrum 8 are first adjusted. For example, the rock climbing fulcrum 8 is first selected to be installed in one of a plurality of strip grooves arranged at intervals along a first direction, so as to achieve position adjustment of the rock climbing fulcrum 8 in a first direction, such as the left and right direction; then the rock climbing fulcrum 8 is pre-fixed at the strip groove on the mounting plate, and then the rock climbing fulcrum 8 is moved along the strip groove so that the rock climbing fulcrum 8 moves in a direction perpendicular to the first direction, such as the up and down direction, so as to achieve position adjustment of the rock climbing fulcrum 8 in the up and down direction, and then the position of the rock climbing fulcrum 8 relative to the strip groove is fixed; since the mounting plate 1 is movably connected to the bracket 2, the mounting plate 1 can be rotated relative to the bracket 2 to achieve angle adjustment of the rock climbing fulcrum 8 until the rock climbing fulcrum is The tested part of point 8 is perpendicular to the central axis of the pressure element 5, such as the rubber head, so that the current angle of the climbing fulcrum 8 can withstand the maximum external force, avoiding the tested part of the climbing fulcrum 8 and the axis of the pressure element to form other angles, such as acute angles, to generate components of force in other directions, thereby correspondingly improving the accuracy of the detection operation of the structural integrity of the climbing fulcrum 8 and preparing for subsequent detection operations; in other words, by adjusting the bar grooves at different positions of the climbing fulcrum 8 fixed on the mounting plate 1, and the climbing fulcrum 8 can slide up and down in the corresponding bar grooves 11, and adjusting the inclination angle of the mounting plate 1 relative to the top plate 22 of the bracket 2, it is possible to realize the convenient installation of climbing fulcrums of different specifications (such as size, weight, etc.) and different shapes (such as different shapes) in three-dimensional space at multiple angles and in multiple directions, thereby achieving the purpose of accurate and efficient detection of their structural integrity.

[0043] Subsequently, the force-applying assembly 3 disposed on the bracket 2 can be operated to drive the force sensor 4 and the pressure element 5 to move simultaneously in the second direction through the force-applying assembly 3, so as to approach and abut against the rock climbing fulcrum 8, so that the force-applying assembly 3 applies a preset target thrust to the rock climbing fulcrum 8 through the pressure element 5 and lasts for 1 minute. The force sensor 4 can detect whether the thrust of the pressure element 5 on the rock climbing fulcrum 8 reaches the preset target thrust. If the rock climbing fulcrum 8 is structurally intact within 1 minute, it is determined that the current specification of the rock climbing fulcrum 8 meets the relevant standard requirements; conversely, if the rock climbing fulcrum is intact within 1 minute, it is determined that the current specification of the rock climbing fulcrum 8 meets the relevant standard requirements; If cracks or breakage occurs, it is judged that the current specification of the rock climbing fulcrum does not meet the relevant standard requirements, thereby realizing the structural integrity detection operation of the rock climbing fulcrum of the current specification and shape; when it is necessary to detect the structural integrity of rock climbing fulcrums of other specifications and shapes, the position and angle of the rock climbing fulcrum can be adjusted according to the above-mentioned method, and then the position and angle of the rock climbing fulcrum relative to the pressure element 5 can be changed to realize the structural integrity detection operation of rock climbing fulcrums of different specifications and shapes, and the accuracy and effectiveness of the structural integrity detection of rock climbing fulcrums of different specifications and shapes can be guaranteed.

[0044] Optionally, combined Figure 1 As shown, the first direction is a horizontal extension direction, the extension direction of the strip groove 11 is perpendicular to the first direction, and the strip groove 11 is used for fasteners to pass through to fix the climbing fulcrum.

[0045] Specifically, combined Figure 3 As shown, since the mounting plate 1 can rotate relative to the bracket 2, the mounting plate 1 can present different postures. For example, the mounting plate 1 can be set horizontally, vertically, or tilted.

[0046] The plurality of strip grooves 11 are arranged horizontally at intervals. When the mounting plate 1 is arranged horizontally, the strip grooves 11 extend horizontally. When the mounting plate 1 is arranged vertically, the strip grooves 11 extend vertically. The strip grooves 11 can be waist-shaped grooves, rectangular grooves, and the like.

[0047] The strip groove 11 can be a through hole structure that passes through the mounting plate 1, or it can be a groove structure that does not pass through the mounting plate 1; for example, when the strip groove 11 is a through hole structure, the fastener completely passes through the rock climbing fulcrum and the strip groove 11; if the strip groove 11 is a groove structure that does not pass through the mounting plate 1, in this case, the groove structure can be a T-slot, and the T-slot refers to the strip groove being cut in a direction perpendicular to the mounting plate, and the strip groove after cutting is a T-shaped structure. At this time, the fastener may include a T-bolt and a nut, the head end of the T-bolt is embedded in the groove, and the screw end of the T-bolt passes through the strip groove and passes through the rock climbing fulcrum, and then the nut is connected, so that the rock climbing fulcrum is fixed to the strip groove position on the mounting plate through the fastener.

[0048] The rock climbing fulcrum can be installed on the mounting plate 1 in the following manner, for example, the fastener includes a fastening bolt and a fixing nut, and the fastening bolt is passed through the rock climbing fulcrum and the mounting plate 1, and connected with the fixing nut, so that the rock climbing fulcrum can be slidably installed on the strip groove 11 of the mounting plate 1 through the fastener. Specifically, by loosening the fastener so that the fastener slides in the strip groove, the rock climbing fulcrum 8 can be driven by the fastener to move and adjust in a direction perpendicular to the first direction. After moving into position, the fastener is tightened so that the fastener and the rock climbing fulcrum 8 are fixed relative to the strip groove, which not only realizes the fixing of the position of the rock climbing fulcrum 8 relative to the mounting plate 1, but also can ensure the feasibility and convenience of fixing the rock climbing fulcrum on the mounting plate by adjusting the tightness of the fastener.

[0049] In this optional embodiment, by selectively installing the climbing fulcrum in different strip grooves 11 and adjusting its position along the extension direction of the strip groove 11, it is possible to adjust the position of the climbing fulcrum in a two-dimensional direction on the entire mounting plate 1; thereby, the measured parts of the climbing fulcrums of different sizes and shapes can correspond to the position of the pressure element 5.

[0050] Optionally, combined Figure 3 As shown, the bracket 2 includes a supporting vertical plate 21 and a top plate 22, the supporting vertical plate 21 is arranged vertically, and the top plate 22 is vertically connected to the supporting vertical plate 21; the force-applying component 3 is installed on the side wall of the supporting vertical plate 21 away from the top plate 22, and the top end of the mounting plate 1 is movably connected to the top plate 22.

[0051] Specifically, the support vertical plate 21 is arranged vertically, and the top plate 22 is arranged horizontally, so the top plate 22 is vertically connected to the support vertical plate 21. The force-applying assembly 3 and the top plate 22 can be located on different sides of the support vertical plate 21, for example, the top plate 22 is arranged on the rear side of the support vertical plate 21, and the force-applying assembly 3 is arranged on the front side of the support vertical plate 21. Since the mounting plate 1 is usually arranged obliquely, the top end of the mounting plate 1 refers to the front end of the mounting plate 1, and the bottom end of the mounting plate 1 refers to the rear end of the mounting plate 1.

[0052] The bracket 2 also includes a base 25, which can be installed on a platform or the ground, and the support vertical plate 21 can be vertically installed on the base 25, so the base 25 can realize the vertical installation operation of the support vertical plate 21, and correspondingly improve the installation stability of the support vertical plate 21.

[0053] In this optional embodiment, since the force-applying assembly 3 is installed on the side wall of the support vertical plate 21 away from the top plate 22, in other words, the force-applying assembly 3 and the mounting plate 1 are located on different sides of the support vertical plate 21, thereby providing a movement space for the pressure element 5 to move along the second direction under the thrust of the force-applying assembly 3. The top end of the mounting plate 1 is movably connected to the top plate 22, so that the angle adjustment operation of the rock climbing fulcrum on the mounting plate 1 is achieved by rotating the mounting plate 1 relative to the top plate 22.

[0054] Optionally, combined Figure 1 and Figure 4 As shown, the detection device for testing the structural integrity of a rock climbing fulcrum also includes a movable part 6, which includes a first bushing 61, a first rotating shaft 62 and a second bushing 63. A plurality of the first bushings 61 are arranged at intervals on the top plate 22, and the second bushing 63 is arranged on the mounting plate 1. The first bushing 61 and the second bushing 63 are respectively sleeved on the first rotating shaft 62, and the mounting plate 1 is used to rotate relative to the top plate 22 around the first rotating shaft 62 through the second bushing 63.

[0055] Specifically, a plurality of first sleeves 61 are fixedly installed on the top plate 22 at intervals, and a second sleeve 63 is fixedly installed on the mounting plate 1 . The plurality of first sleeves 61 and the second sleeves 63 may be arranged in an interval arrangement along the first direction.

[0056] When the number of the second sleeve 63 is one, the second sleeve 63 can be located in the middle of the top of the mounting plate 1 to ensure that the left and right ends of the mounting plate 1 are stable and reduce the possibility of left and right tilting; if the number of the second sleeve 63 is more than two, more than two second sleeves 63 are arranged at intervals and fixedly installed on the mounting plate 1. The first sleeve 61 provides a mounting base for the first rotating shaft 62.

[0057] The mounting plate 1 is used to rotate around the first rotating shaft 62 relative to the top plate 22 through the second bushing 63, which means that the first bushing 61 and the second bushing 63 are respectively interference fit with the first rotating shaft 62, so that the first rotating shaft 62 can rotate in the first bushing 61 and the second bushing 63, thereby realizing the mounting plate 1 rotating around the first rotating shaft 62 relative to the top plate through the second bushing 63.

[0058] In this optional embodiment, since the first shaft sleeve 61 and the second shaft sleeve 63 are respectively sleeved on the first rotating shaft 62, the second shaft sleeve 63 arranged on the mounting plate 1 can rotate around the first rotating shaft 62 relative to the top plate 22 within a certain angle range, so as to achieve angle adjustment of the climbing fulcrum on the mounting plate 1 by adjusting the inclination angle of the mounting plate 1 relative to the top plate 22.

[0059] Optionally, combined Figure 4 As shown, the second shaft sleeve 63 is located between two adjacent first shaft sleeves 61 , and the second shaft sleeve 63 is used to slide on the first rotating shaft 62 along the first direction.

[0060] Specifically, a plurality of first sleeves 61 and second sleeves 63 may be spaced apart along the first direction, the second sleeve 63 may be located between two adjacent first sleeves 61, and the second sleeve 63 may slide along the first direction on the first rotating shaft 62, at which time the distance between two adjacent first sleeves 61 is the maximum moving distance of the second sleeve 63 on the mounting plate 1 along the first direction.

[0061] Since the second sleeve 63 can slide on the first rotating shaft 62 along the first direction, a linear bearing can be provided between the second sleeve 63 and the first rotating shaft 62 .

[0062] In this optional embodiment, since the second sleeve 63 can slide on the first rotating shaft 62 along the first direction, and the climbing fulcrum can be selectively installed on the strip grooves 11 at different positions arranged at intervals along the first direction on the mounting plate 1, not only can the adjustment range of the left and right position of the climbing fulcrum along the first direction be increased, but also the left and right position adjustment accuracy of the climbing fulcrum in the first direction can be improved.

[0063] Optionally, combined Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the detection device for testing the structural integrity of the rock climbing fulcrum further includes an angle locking assembly 7, the bracket 2 further includes two guide side plates 23 and two fixing plates 24, the two guide side plates 23 are arranged at intervals along a first direction, the two ends of the support vertical plate 21 along the first direction are respectively connected to the two guide side plates 23, the two fixing plates 24 are arranged at intervals along the first direction, and the end of the guide side plate 23 away from the support vertical plate 21 is connected to the fixing plate 24;

[0064] Arc grooves 231 are respectively arranged on the two guide side plates 23, and the angle locking assembly 7 includes a second rotating shaft 71, a connecting rod 72 and a positioning rod structure 73. The two ends of the second rotating shaft 71 are passed through the arc grooves 231 corresponding to the two guide side plates 23, and the second rotating shaft 71 is used to move in the arc grooves 231; the two ends of the connecting rod 72 are respectively connected to the mounting plate 1 and the second rotating shaft 71, and the two ends of the positioning rod structure 73 are respectively connected to the second rotating shaft 71 and the fixed plate 24, and the length of the positioning rod structure 73 is adjustable.

[0065] Specifically, the two ends of the support vertical plate 21 along the first direction are respectively connected to the corresponding guide side plates 23, so that the guide side plates 23 and the support vertical plate 21 can form an integrated structure; the mounting plate 1 can be located between the two guide side plates 23 arranged relatively spaced apart, so that the guide side plates 23 will not interfere with the rotation of the mounting plate 1; each guide side plate 23 is vertically connected to the support vertical plate 21, as shown in FIG. Figure 3 The two fixing plates 24 can be arranged outside the two guide side plates 23, and the fixing plates 24 can be fixedly connected to the outer wall of the guide side plates 23, and the fixing plates 24 provide a mounting base for the positioning rod structure 73, as shown in FIG. Figure 2 shown.

[0066] An arc-shaped slide groove 231 is provided on each guide side plate 23, and the second rotating shaft 71 is extended along the first direction, and the two ends of the second rotating shaft 71 are respectively passed through the arc-shaped slide grooves 231 corresponding to the two guide side plates 23. Therefore, the arc-shaped slide groove 231 provides a guide for the movement of the second rotating shaft 71 driven by the mounting plate 1.

[0067] The lines connecting the two ends of the arc-shaped slide groove 231 and the first rotating shaft can form a fan-shaped structure, and the angle of the fan-shaped structure is 90 degrees. For example, the upper end of the arc-shaped slide groove 231 is lower than or flush with the top plate, and the lower end of the arc-shaped slide groove 231 can be below the first rotating shaft. Since the angle of the fan-shaped structure is 90 degrees, the angle adjustment range of the mounting plate and the climbing fulcrum on the mounting plate is also basically within the range of 0 degrees to 90 degrees.

[0068] like Figure 3As shown in FIG. 1 , when the mounting plate 1 is rotated to a horizontal state, the climbing fulcrum 8 fixed on the mounting plate 1 is indicated by a dotted line; when the mounting plate 1 is rotated to an inclined state, the climbing fulcrum 8 fixed on the mounting plate 1 is indicated by a solid line; when the mounting plate 1 is rotated to a vertical state, the climbing fulcrum 8 fixed on the mounting plate 1 is indicated by a solid line. Figure 3 It is not shown in the figure, but it should be noted that no matter what posture the mounting plate 1 is in, by adjusting the position of the climbing fulcrum 8 on the mounting plate 1, the part to be tested of the climbing fulcrum 8 can be made higher than the top plate and correspond to the position of the pressure element, so as to ensure that when the pressure element moves to approach the climbing fulcrum 8, the pressure element can abut against the climbing fulcrum 8.

[0069] One end of the connecting rod 72 can be sleeved outside the second rotating shaft 71 to rotate relative to the second rotating shaft 71, and the area below the top of the mounting plate 1, such as the middle or bottom, is connected to the other end of the connecting rod 72. In short, the connecting rod 72 serves to connect the second rotating shaft 71 and the mounting plate 1, so that when the top of the mounting plate 1 rotates relative to the top plate 22 through the movable part 6, the area below the top of the mounting plate 1 can cause the second rotating shaft 71 to move in the arc-shaped slide groove 231 through the connecting rod 72.

[0070] The positioning rod structure 73 is used to adjust its own length so that the two ends of the positioning rod structure 73 are respectively connected to the second rotating shaft 71 and the fixed plate 24 to lock the position of the mounting plate 1 after the angle adjustment, so as to avoid changes in the angle of the mounting plate 1 during the structural integrity inspection of the rock climbing fulcrum.

[0071] In which, the angle locking assembly 7 may include at least one positioning rod structure 73. For example, when the number of the positioning rod structures 73 is one, it can be installed on the side of one of the guide side plates 23 away from the other guide side plate 23; when the number of the positioning rod structures 73 is two, the two positioning rod structures 73 are respectively arranged on the outer sides of the two guide side plates 23, and one end of each positioning rod structure 73 is connected to the end of the second rotating shaft 71 passing through the arc-shaped slide groove, and the other end of each positioning rod structure 73 is connected to the fixed plate 24.

[0072] In this optional embodiment, the angle of the climbing fulcrum 8 on the mounting plate 1 can be adjusted in the following manner. For example, the mounting plate 1 is rotated relative to the top plate 22 via the movable part 6. During this process, the area below the top of the mounting plate 1 drives the second rotating shaft 71 to move in the arc-shaped slide groove 231 via the connecting rod 72. After adjusting to a suitable angle, the length of the positioning rod structure 73 can be adjusted to lock the current angle position of the mounting plate 1, so as to realize the angle adjustment operation of the climbing fulcrum on the mounting plate 1.

[0073] Optionally, combined Figure 5As shown, the positioning rod structure 73 includes a positioning rod body 731 and a positioning nut 732. One end of the positioning rod body 731 is movably sleeved on the second rotating shaft 71. A waist-shaped hole is provided on the fixing plate 24. One end of the positioning rod body 731 away from the second rotating shaft 71 is movably inserted into the waist-shaped hole of the fixing plate 24 and connected to the positioning nut 732.

[0074] Specifically, the two ends of the positioning rod structure 73 can be connected to the second rotating shaft 71 and the fixed plate 24 in the following manner. For example, the positioning rod body 731 includes an annular portion and a screw portion of an integral structure. The annular portion is sleeved on the end of the second rotating shaft 71 that passes through the guide side plate 23, and the annular portion can move relative to the end of the second rotating shaft 71, such as rotating. The waist-shaped hole on the fixed plate 24 is extended vertically, and the screw portion is passed through the waist-shaped hole of the fixed plate 24 and is connected to the positioning nut 732. The position of the positioning nut 732 on the screw portion can be adjusted to lock the distance between the second rotating shaft 71 and the fixed plate 24, thereby achieving the locking of the angle of the mounting plate 1.

[0075] Of course, other mechanical structures such as telescopic sleeves that have similar functions to the positioning rod structure 73 (for example, used to lock the angle of the mounting plate 1) are also within the scope of protection of the present invention, wherein the telescopic sleeve includes multiple telescopic sections, and two adjacent telescopic sections are connected by threaded sleeves. The length of the entire telescopic sleeve can be adjusted by rotating the two adjacent telescopic sections, and the distance here is not too much.

[0076] In this optional embodiment, before the mounting plate 1 is rotated relative to the top plate to adjust the angle, the positioning nut 732 can be removed from the end of the positioning rod body 731, or the positioning nut 732 can be loosened to ensure that there is a sufficient length between one end of the positioning rod body 731 connected to the second rotating shaft 71 and the fixing plate; when the mounting plate 1 is rotated relative to the top plate to adjust the angle, the mounting plate 1 will drive the second rotating shaft 71 to slide along the arc of the arc sliding groove 231 in the arc sliding groove 231 through the connecting rod 72, and at this time, the second rotating shaft 71 will drive the front end of the positioning rod body 731 to move along the arc of the arc sliding groove 231, so that the rear end of the positioning rod body 731 will move up and down and forward and backward in the waist-shaped hole of the fixing plate 24; After the mounting plate 1 is rotated to a suitable angle relative to the top plate 22 through the movable part 6, since the mounting plate 1 is in an inclined state at this time, the mounting plate 1 will generate a component force (thrust) toward the direction of the supporting vertical plate 21 on the second rotating shaft 71 through the connecting rod 72. At this time, the positioning nut 732 can be rotated to change its position on the positioning rod body 731. In other words, the positioning nut 732 is tightened, and the positioning nut 732 is located on the side of the fixed plate 24 away from the second rotating shaft 71, so that the second rotating shaft 71 is pulled away from the supporting vertical plate 21 through the cooperation of the positioning nut 732 and the positioning rod body 731, so as to offset the component force of the connecting rod 72 on the second rotating shaft 71, thereby achieving the locking of the current angle of the mounting plate 1.

[0077] Optionally, combined Figure 2 , Figure 3 and Figure 6 As shown, the angle locking assembly 7 includes a plurality of connecting rods 72, and the plurality of connecting rods 72 are arranged at intervals along the first direction;

[0078] The connecting rod 72 includes a connecting rod body 721 and a fastening nut 722 . One end of the connecting rod body 721 is sleeved on the second rotating shaft 71 . The connecting rod body 721 passes through the mounting plate 1 and is connected to the fastening nut 722 .

[0079] Specifically, combined Figure 2 As shown, a plurality of connecting rods 72 are arranged at intervals along the first direction. For example, when the number of the connecting rods 72 is two, the two connecting rods 72 are arranged at both ends of the mounting plate 1 along the first direction.

[0080] Combination Figure 3 and Figure 6As shown, the two ends of the connecting rod 72 can be connected to the second rotating shaft 71 and the mounting plate 1 in the following manner. For example, the connecting rod body 721 includes an annular portion and a bolt portion of an integral structure. The annular portion is sleeved on the second rotating shaft 71, and the annular portion can rotate relative to the end of the second rotating shaft 71. The bolt portion is penetrated through the fixing plate 24 and connected to the fastening nut 722, so that the connection and fixation between the mounting plate 1 and the second rotating shaft 71 are achieved through the connecting rod 72, so that when the mounting plate 1 rotates relative to the top plate 22, the second rotating shaft 71 is driven by the connecting rod 72 to slide in the arc-shaped slide groove 231 of the guide side plate 23, and cooperates with the positioning rod structure 73 to achieve locking of the angular position of the mounting plate 1 after rotation.

[0081] In this optional embodiment, before the mounting plate 1 rotates relative to the top plate 22, one end of the connecting rod body 721 can be sleeved on the second rotating shaft 71, and the other end of the connecting rod body 721 is passed through the mounting plate 1 and connected with the fastening nut 722, so that the mounting plate 1 and the second rotating shaft 71 are fixed as an integral structure through the connecting rod 72, so that during the rotation of the mounting plate 1, the second rotating shaft 71 can be driven by the connecting rod 72 to rotate in the arc-shaped slide groove of the guide side plate 23. After the mounting plate 1 rotates to a suitable angle relative to the top plate 22, the mounting plate 1 is basically in an inclined state. At this time, the positioning nut 732 is tightened to fix the position of the second rotating shaft 71 in the arc-shaped slide groove 231 through the cooperation of the positioning nut 732 on the side of the fixing plate 24 away from the supporting vertical plate 21 and the positioning rod body 731, thereby realizing the position locking of the current angle of the mounting plate 1.

[0082] Optionally, combined Figure 3 and Figure 7 As shown, the force-applying assembly 3 includes a reaction plate 31, a support rod 32 and a force-applying power unit 33. The reaction plate 31 is arranged on the side of the support vertical plate 21 away from the top plate 22. The two ends of the support rod 32 are respectively connected to the reaction plate 31 and the support vertical plate 21. The force-applying power unit 33 is penetrated by the reaction plate 31 and the support vertical plate 21. The force-applying power unit 33 is connected to the pressure element 5 through the force sensor 4.

[0083] Specifically, the reaction plate 31 and the top plate 22 are located on different sides of the support vertical plate 21. For example, the reaction plate 31 is arranged on the front side of the support vertical plate 21, and the top plate 22 is arranged on the rear side of the support vertical plate 21. The reaction plate 31 can be fixedly mounted on the support vertical plate 21 by a support rod 32. For example, the support rod 32 is a horizontally arranged long bolt structure, and the two ends of the long bolt structure are respectively connected to the reaction plate 31 and the support vertical plate 21.

[0084] A part of the structure of the force-applying power unit 33 is installed on the reaction plate 31, and another part of the structure is penetrated through the supporting vertical plate 21. Therefore, the reaction plate 31 refers to when the pressure element 5 applies the thrust of the force-applying power unit 33 to the rock climbing fulcrum, the rock climbing fulcrum will reversely transmit the thrust through the pressure element 5 and the force sensor 4 to the force-applying power unit 33, so that the reaction plate 31 bears a reaction force opposite to the thrust. One end of the force sensor 4 is connected to the force-applying power unit 33, and the other end is connected to the pressure element 5.

[0085] In this optional embodiment, when it is necessary to apply a thrust to the climbing fulcrum on the mounting plate 1 to detect the structural integrity of the climbing fulcrum (for example, anti-fixing force), a thrust along the second direction can be provided by the force-applying power unit 33 installed on the reaction plate 31 to push the force sensor 4 and the pressure element 5 close to until they abut against the climbing fulcrum on the mounting plate 1, so that the thrust provided by the force-applying power unit 33 is transmitted to the climbing fulcrum via the force sensor 4 and the pressure element 5 in sequence. The force sensor 4 detects whether the thrust of the force-applying power unit 33 on the climbing fulcrum reaches the target thrust. If the rock climbing fulcrum remains structurally intact for 1 minute under the corresponding target thrust, it is judged that the current specification of the rock climbing fulcrum meets the relevant standard requirements; otherwise, if the rock climbing fulcrum cracks or breaks within 1 minute, it is judged that the current specification of the rock climbing fulcrum does not meet the relevant standard requirements.

[0086] The force-applying power unit 33 is a power device that can provide a certain thrust and is directed toward the climbing fulcrum. It can be a horizontally arranged electric push rod, a hydraulic cylinder, etc., or other types such as the power devices described below, which are not specifically limited here.

[0087] Optionally, combined Figure 7 As shown, the force-applying power part 33 includes a force bolt 331 and a force transmission member 332. A threaded hole is provided on the reaction plate 31. The force bolt 331 is threadedly penetrated in the threaded hole. The end of the force bolt 331 has a circular portion. One end of the force transmission member 332 has a accommodating cavity. The circular portion of the force bolt 331 is embedded in the accommodating cavity of the force transmission member 332. The force bolt 331 is used to rotate relative to the force transmission member 332. The other end of the force transmission member 332 is penetrated in the supporting vertical plate 21 and connected to the force sensor 4. The force bolt 331 is used to drive the force transmission member 332, the force sensor 4 and the pressure element 5 to move along the second direction by rotating in the threaded hole.

[0088] Specifically, a through hole structure may be provided on the support vertical plate 21 above the top plate 22 to facilitate the force transmission member 332 to pass through, and the through hole structure provides a certain guiding effect for the linear motion of the force transmission member 332 along the second direction, so as to prevent the force transmission member 332 from tilting during the backward or forward thrusting process along the second direction. The force bolt 331 is inserted into the threaded hole, and the force bolt 331 is rotated so that the force bolt 331 generates a backward thrust toward the rock climbing fulcrum during the rotational motion in the threaded hole, or generates a forward pulling force away from the rock climbing fulcrum.

[0089] The force transmitting member 332 may be connected to the force transmitting member 332 in the following manner, for example, one end of the force transmitting member 331, for example, the front end, is provided with a handle portion to facilitate operation by the operator, the middle portion of the force transmitting member 331 is passed through the threaded hole of the reaction plate 31, and the other end of the force transmitting member 331, for example, the rear end, has a circular portion, which may be a ball head or a hemispherical portion, and one end of the force transmitting member 332, for example, the front end, has a receiving cavity, and the other end of the force transmitting member 332, for example, the rear end, may be connected to the force sensor 4 through a bolt fastener, and the force sensor 4 may be connected to the pressure element 5 through the bolt fastener; wherein, the circular portion at the rear end of the force transmitting member 331 is embedded in the receiving cavity of the force transmitting member 332, so that when the force transmitting member 331 is pushed backward toward the climbing fulcrum in a rotational manner, the circular portion of the force transmitting member 331 may rotate in the receiving cavity of the force transmitting member 332, and at this time, the force transmitting member 332 may convert the backward rotational thrust of the force transmitting member 331 into a backward horizontal thrust acting on the pressure element.

[0090] According to the standard EN 12572-3:2017(E) "Artificial climbing structures. Part 3: Safety requirements and test methods for climbing supports", the climbing supports that have been soaked and treated with freeze-thaw cycles were installed and tested one by one according to the torque provided by the manufacturer. The results all met the expected requirements. See below for details.

[0091] Table 1.

[0092]

[0093] Table 1

[0094] Table 1 records the installation and debugging time and test results of climbing supports of different specifications, such as different materials and different models and sizes.

[0095] Take the first rock climbing fulcrum of the specification in Table 1 as an example. The material of the rock climbing fulcrum is a resin composite material, the average diameter is 36 mm, the size is XS, and the installation time of the rock climbing fulcrum on the strip groove of the mounting plate is as follows: Figure 7 X-axis direction) and the inclination angle of the climbing fulcrum relative to the top plate through the mounting plate (see Figure 7 The total adjustment time in the Z-axis direction is about 4.5 minutes. Then, the target thrust can be applied to the climbing fulcrum in the following way:

[0096] For example, when the force bolt 331 is rotated forward, the force bolt 331 generates a backward rotational thrust approaching the rock climbing fulcrum, and the force transmission member 332 converts the rotational thrust into a linear thrust, so that the force transmission member 332, the force sensor 4 and the pressure element 5 approach until they abut the rock climbing fulcrum under the thrust of the force bolt 331. The force sensor 4 can detect whether the thrust of the pressure element 5 acting on the rock climbing fulcrum has reached the target thrust. When the rock climbing fulcrum is subjected to the target thrust of, for example, 2.620 kN, and lasts for 1 minute, and the structure is still intact (for example, no cracks or breakage are generated), it is judged that the structural integrity of the rock climbing fulcrum of this specification meets the standard requirements.

[0097] After the structural integrity test of the climbing fulcrum of this specification, the force bolt 331 can be rotated in the reverse direction to make the force bolt 331 generate a forward rotational pulling force away from the climbing fulcrum, so that the force transmission member 332, the force sensor 4 and the pressure element 5 are away from the climbing fulcrum under the pulling force of the force bolt 331, thereby preparing for the structural integrity test of the climbing fulcrum of the next specification, shape and material. Figure 7 The positive direction of the Y axis of the coordinate system is consistent with the positive direction of the Y axis of the coordinate system. Figure 7 The Y axis of the coordinate system is inversely proportional.

[0098] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
