[0002] The tensile force sensor is a force detection device for an attached lifting scaffold (hereinafter referred to as a climbing scaffold), which is the main data source of the intelligent control system, ensuring data guarantee when the climbing scaffold is lifted. When the force on each position exceeds 15%, the intelligent control system will automatically alarm; when the force on each position exceeds 30%, the intelligent control system will automatically stop.

[0003] As a leased turnover equipment, the climbing scaffold needs to be withdrawn to the maintenance factory for repair and detection after each project is used to ensure good operation of the equipment when used in the next project. The repair and detection include using a manual hoist or an electric hoist to apply a force test to the tensile force sensor to detect whether the tensile force sensor is damaged. However, this method can only test a single sensor, and requires a large site area and is difficult to operate. Summary of the Invention

[0004] This application provides a detection device for a tensile force sensor that is beneficial to improving the detection efficiency and reducing the difficulty of detection operation.

[0005] In a first aspect, an embodiment of this application provides a detection device for a tensile force sensor. The detection device for a tensile force sensor includes a base, a top platform, and a driving member. The base includes a bottom plate and a sliding track. The sliding track is provided with a plurality of mounting rods at intervals in a first direction; the top platform is slidably connected to the sliding track in a second direction. The top platform is provided with a plurality of hanging rods at intervals in the first direction. The number of the hanging rods is the same as that of the mounting rods and they are arranged at intervals in the first direction in a one-to-one correspondence. The hanging rods and the corresponding mounting rods are used to pass through two force-receiving holes of the same tensile force sensor; the second direction is perpendicular to the first direction; the driving member is connected to the bottom plate, and the output end of the driving member is connected to the top platform. The driving member is used to push the top platform to reciprocally slide in the second direction so that the hanging rods approach or move away from the corresponding mounting rods.

[0006] According to the first aspect, in a possible implementation manner, a positioning groove is formed at the end of the hanging rod, and the positioning groove is used to position the tensile force sensor.

[0007] According to the first aspect, in a possible implementation manner, positioning grooves are formed at both ends of the hanging rod.

[0008] According to the first aspect, in a possible implementation, the sliding track has a mounting cavity, and the driving member is disposed in the mounting cavity; the sliding track has a sliding groove extending in the second direction and communicating with the mounting cavity; a part of the top platform is disposed in the mounting cavity, and the remaining part of the top platform extends out of the sliding groove, and the hanging rod is disposed on the part of the top platform that extends out.

[0009] According to the first aspect, in a possible implementation, the sliding track includes two columns connected to the bottom plate, and a mounting groove is formed on one side of each column. The two columns are disposed opposite to each other to form the sliding groove between the edges of the two columns and form the mounting cavity between the two mounting grooves; both ends of the top platform pass through the sliding grooves on both sides.

[0010] According to the first aspect, in a possible implementation, the sliding track further includes two mounting plates, and the two mounting plates are respectively connected to the two columns in a one-to-one correspondence, and the two mounting plates are connected to the opposite sides of the two columns; the mounting rod passes through the two mounting plates, and at least one end of the mounting rod protrudes from the mounting plate to pass through the force-receiving hole of the tension sensor.

[0011] According to the first aspect, in a possible implementation, the base further includes a reinforcing plate, and the reinforcing plate connects the two columns, and the reinforcing plate is located at the top end and / or the bottom end of the column.

[0012] According to the first aspect, in a possible implementation, the top platform includes a main beam having a hollow portion, and the hanging rod passes through the opposite side plates of the main beam in the third direction, and the third direction, the second direction, and the first direction are perpendicular to each other in pairs.

[0014] According to the first aspect, in a possible implementation, the driving member includes one of a hydraulic cylinder, a pneumatic cylinder, a jack, and a linear motor.

[0015] This application provides a tensile sensor detection device. When the tensile sensor detection device conducts detection, only two operations are required: fixing the tensile sensor and starting the driving member. When fixing the tensile sensor, first pass the circular force-bearing hole of the tensile sensor through the hanging rod on the top platform to suspend the tensile sensor. Then, align the waist-shaped force-bearing hole with the mounting rod on the base and pass it through. Due to the design characteristics of the waist-shaped hole, there is a certain gap between both ends of the mounting rod and the waist-shaped hole, which facilitates installation and adjustment and reduces the operation difficulty. After starting the driving member, the driving member pushes the top platform to slide upward in the vertical direction. As the top platform rises, the hanging rod drives the tensile sensor to move upward together. When the mounting rod contacts one end of the waist-shaped force-bearing hole, due to the continuous upward pulling force of the hanging rod, the waist-shaped force-bearing hole is stretched along its extending direction, thus simulating the force-bearing situation of the tensile sensor in actual use. This application also realizes the simultaneous detection of multiple tensile sensors through the cooperation of multiple hanging rods and multiple mounting rods, improving the detection efficiency.

[0027] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the present application in the specification are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The term "and / or" used in the present application includes any and all combinations of one or more of the related listed items.

[0028] Next, some embodiments of the present application will be described in detail in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0029] Please refer to Figure 1 and Figure 2 , the present application provides a tensile force sensor detection device (hereinafter referred to as the detection device 100). The detection device 100 is used to perform a force test on the tensile force sensor 200 to detect whether the tensile force sensor 200 is damaged. There are two spaced-apart force-receiving holes on the tensile force sensor 200. One of the force-receiving holes is a circular force-receiving hole 201, and the other force-receiving hole is a waist-shaped force-receiving hole 202. The extending direction of the waist-shaped force-receiving hole 202 is consistent with the spacing direction of the two force-receiving holes. An electrical component 203 is provided between the two force-receiving holes and is sealed with glue; a signal interface 204 is provided on one side of the tensile force sensor 200 and is connected to an external control system through a data cable.

[0030] In this application, the first direction is the left - right direction, the second direction is the up - down direction, and the third direction is the front - back direction. The third direction, the second direction, and the first direction are perpendicular to each other in pairs.

[0031] Please refer to Figures 1 to 3 , the detection device 100 includes a base 10, a top platform 20, and a driving member 40. The base 10 includes a bottom plate 11 and sliding rails 12. A plurality of mounting rods 13 are arranged at intervals along the first direction on the sliding rails 12; the top platform 20 is slidably connected to the sliding rails 12 along the second direction. A plurality of hanging rods 21 are arranged at intervals along the first direction on the top platform 20. The number of the hanging rods 21 is the same as that of the mounting rods 13 and they are arranged at intervals along the first direction in one - to - one correspondence. The hanging rods 21 and the corresponding mounting rods 13 are used to pass through two stress holes of the same tension sensor 200; the second direction is perpendicular to the first direction; the driving member 40 is connected to the bottom plate 11, and the output end of the driving member 40 is connected to the top platform 20. The driving member 40 is used to push the top platform 20 to slide reciprocally along the second direction so that the hanging rods 21 approach or move away from the corresponding mounting rods 13.

[0032] Before the test, first, pass the circular stress hole 201 of the tension sensor 200 through the hanging rod 21 on the top platform 20 to realize the suspension of the tension sensor 200. Then, align the waist - shaped stress hole 202 with the mounting rod 13 on the base 10 and pass through it. Due to the design characteristics of the waist - shaped hole, there are certain gaps between the mounting rod 13 and both ends of the waist - shaped hole, which is convenient for installation and adjustment and reduces the operation difficulty. After starting the driving member 40, the driving member 40 pushes the top platform 20 to slide upward along the vertical direction. As the top platform 20 rises, the hanging rod 21 drives the tension sensor 200 to move upward together. When the mounting rod 13 contacts one end of the waist - shaped stress hole 202, due to the continuous upward pulling force of the hanging rod 21, the waist - shaped stress hole 202 is stretched along its extending direction, thus simulating the stress condition of the tension sensor 200 in actual use. During this process, the external control system receives the output signal of the tension sensor 200 through the data line, and monitors and records the performance of the tension sensor 200 in real - time. By observing parameters such as signal changes and deformation degrees, it can be evaluated whether the tension sensor 200 is damaged or has performance problems. This application also realizes the simultaneous detection of multiple tension sensors 200 through the cooperation of multiple hanging rods 21 and multiple mounting rods 13, improving the detection efficiency.

[0033] In other embodiments, it is also possible that the hanging rod 21 passes through the waist - shaped stress hole 202 and the mounting rod 13 passes through the circular stress hole 201. This application does not make a limitation on this.

[0034] Among them, the driving member 40 includes one of a hydraulic cylinder, a pneumatic cylinder, a jack, and a linear motor.

[0035] It should be noted that the detection device 100 claimed in this application does not include an external control system. The functions of detection, recording, calculation, comparison, judgment, etc. of the control system are conventional techniques in this field, and this application does not make any limitations thereto.

[0036] In one embodiment, a positioning groove 211 is formed at the end of the hanging rod 21. As Figure 6 shown, the positioning groove 211 is used to position the tension sensor 200. The positioning groove 211 is arranged along the circumferential direction of the hanging rod 21, and the two side walls of the positioning groove 211 serve as stop surfaces, which play a good limiting role on the tension sensor 200. The axial movement of the tension sensor 200 during the test is effectively restricted, preventing measurement errors caused by shaking or vibration.

[0037] The shape and size of the positioning groove 211 should be designed according to the specific shape and size of the tension sensor 200 to ensure a good match between the two. For example, the groove width of the positioning groove 211 matches the thickness of the tension sensor 200. If there are specific protrusions or grooves around the circular force-receiving hole 201 of the tension sensor 200, the positioning groove 211 can be designed into a corresponding matching shape.

[0038] Since the tension sensor 200 is suspended on the hanging rod 21, that is, the upper wall surface of the hanging rod 21 is in contact with the hole wall of the circular force-receiving hole 201 of the tension sensor 200. That is, the positioning groove 211 can be provided only on the upper wall surface of the hanging rod 21, and the bottom wall of the positioning groove 211 matches the shape of the hole wall of the circular force-receiving hole 201, enhancing the contact tightness between the two and improving the stability and accuracy of the contact.

[0039] Based on the above embodiment, positioning grooves 211 are formed at both ends of the hanging rod 21. That is, the hanging rod 21 is designed to pass through the top platform 20, and both ends of the hanging rod 21 are exposed and used to hang the tension sensors 200, further increasing the number of tension sensors 200 detected simultaneously and improving the detection efficiency.

[0040] In one embodiment, please refer to Figure 4 and Figure 5 . The sliding track 12 has an installation cavity 121, and the driving member 40 is arranged in the installation cavity 121; the installation cavity 121 accommodates the driving member 40, protecting the driving member 40 from the influence of the external environment and improving the stability and reliability of the driving member 40 during operation. The sliding track 12 has a sliding groove 122 extending along the second direction and communicating with the installation cavity 121; a part of the top platform 20 is arranged in the installation cavity 121, and the rest of the top platform 20 extends out of the sliding groove 122, and the hanging rod 21 is arranged on the extended part of the top platform 20. The sliding groove 122 guides the moving direction of the top platform 20, enabling the top platform 20 to move smoothly and precisely along a predetermined path, avoiding errors caused by deviation and shaking, and improving the accuracy of the test.

[0041] In the example of the first embodiment described above, the sliding track 12 includes two columns 123 connected to the bottom plate 11, and the connection between the columns 123 and the bottom plate 11 is usually welding, bolting or other high-strength connection methods. The two columns 123 are arranged opposite to each other, and a mounting groove is provided on the inner side of each of the two columns 123. The mounting grooves of the two columns 123 are opposite to each other, and together form a mounting cavity 121 for accommodating and protecting the driving member 40. At the same time, a narrow and long sliding groove 122 is formed between the outer edges of the two columns 123. This sliding groove 122 provides a precise guide and a stable path for the movement of the top platform 20.

[0042] Both ends of the top platform 20 can pass through the sliding grooves 122 on both sides, so that the top platform 20 can move along the sliding grooves 122 under the drive of the driving member 40. The exposed portion of the top platform 20 is used to install the hanging rod 21.

[0043] In practical applications, the two columns 123 can use U-shaped plates of the same specifications, and the two U-shaped plates are vertically fixed on the base plate 11, and the notches of the two U-shaped plates are arranged opposite to each other; the integral part can also be grooved to form two columns 123, and this application does not limit this.

[0044] In one embodiment, the sliding track 12 further includes two mounting plates 124, which are connected to the two columns 123 in a one-to-one correspondence, and the two mounting plates 124 are connected to the opposite sides of the two columns 123; the mounting rod 13 passes through the two mounting plates 124, and at least one end of the mounting rod 13 is exposed from the mounting plate 124 to pass through the force-bearing hole of the tension sensor 200. The two mounting plates 124 are respectively connected to the opposite sides of the two columns 123. This connection method can prevent the mounting plates 124 from interfering with the movement of the top platform 20 in the sliding groove 122. The mounting plates 124 can also stably support the columns 123 and disperse the forces and moments received by the columns 123, thereby improving the bearing capacity and stability of the entire sliding track 12.

[0045] The connection between the mounting plate 124 and the column 123 adopts a high-strength connection method, such as welding or precision bolt fastening, to ensure that it can remain stable and not shake even when subjected to a large load. This connection method not only enhances the overall rigidity of the sliding track 12, but also lays a solid foundation for the subsequent installation of the tension sensor 200.

[0046] In order to ensure the stability and reliability of the tension sensor 200 during the test, a reinforcing rib or a supporting structure may be provided between the mounting plate 124 and the column 123 to further improve the stability and bearing capacity of the entire mounting system.

[0047] Furthermore, the base 10 also includes a reinforcing plate 125, which connects the two columns 123. The reinforcing plate 125 can be arranged at the top end, the bottom end, or both ends of the columns 123. The reinforcing plate 125 at the top end of the columns 123 significantly enhances the stability of the top of the test platform, preventing the columns 123 from tilting or shaking when bearing the test load, thereby ensuring the stability and accuracy of the test platform in high-precision or heavy-load tests. The reinforcing plate 125 at the bottom end of the columns 123 tightly fixes the columns 123 and the base plate 11 together to form a stable overall structure.

[0048] In one embodiment, please refer to Figure 6 The top platform 20 includes a main beam 22 with a hollow portion. The hollow design can reduce the overall weight of the top platform 20, making it easier to move and install. The hanging rod 21 passes through the two opposite side plates of the main beam 22 along the third direction to form a stable supporting structure. This layout ensures that the hanging rod 21 can be evenly stressed, effectively dispersing various forces and moments that may be generated during the test, thereby improving the load-bearing capacity and stability of the top platform 20.

[0049] The main beam 22 can be formed by a U-shaped plate and a plate body covering the notch side of the U-shaped plate, or a square tube can be selected. When the main beam 22 can be formed by a U-shaped plate and a plate body covering the notch side of the U-shaped plate, and the two columns 123 are formed by U-shaped plates, the types of raw materials used to manufacture the detection device 100 can be reduced.

[0050] Based on the above embodiment, the top platform 20 includes at least one pair of limit plates 23, and the column 123 is located between the pair of limit plates 23. That is, the main beam 22 is limited between the two columns 123 along the front-back direction, and the column 123 is limited between the two limit plates 23 along the left-right direction, thereby improving the anti-rolling ability of the entire top platform 20.

[0051] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0052] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
