Description

Technical Field

[0001] This utility model relates to the technical field of crane scale testing equipment, and more specifically, to a crane scale testing device. Background Technology

[0002] Currently, when calibrating and testing electronic crane scales, a sensor is connected to the output end of a hydraulic cylinder. The bottom of the sensor is connected to the crane scale, which is then secured to the bottom with a traction rope. When the hydraulic cylinder output end is pulled up, both the crane scale and the sensor display values. The accuracy of the crane scale is judged by comparing these values. To ensure the stability of the entire equipment operation and prevent severe vibrations caused by rapid movement of the hydraulic cylinder output end, the movement speed of the hydraulic cylinder output end is set relatively slowly, resulting in low testing efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a crane scale testing device to improve testing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a crane scale detection device, comprising a fixed frame, the fixed frame including a base plate at the bottom, a fixed seat installed at the upper end of the base plate, and a rope body two connected to the fixed seat; it also includes a roller, the roller being located above the fixed seat and capable of moving up and down, the rope body two passing over the left side of the roller, the rope body two including an inclined section at the bottom, one end of the inclined section abutting against the roller, and the other end of the inclined section being connected to the fixed seat; the upper end of the rope body two is used to connect to the crane scale, and a tension sensor is connected to the top of the crane scale through the rope body one, the tension sensor being fixedly installed on the fixing device, and the fixing device being capable of moving up and down.

[0005] The present invention is further configured such that a driving component is connected to the top of the fixture, the driving component being a hydraulic cylinder, and the fixture also includes a top plate located at the top, with the driving component mounted on the top plate.

[0006] The present invention is further configured such that a tension sensor is inserted into a fixator, a limit plate is installed at the bottom of the fixator, and the rope passes through the limit plate upward and is fixedly connected to the tension sensor.

[0007] The present invention is further configured such that the second rope body includes a straight segment, one end of which is connected to the crane scale, and the other end is connected to the inclined segment, with the inclined segment and the straight segment forming an obtuse angle.

[0008] The present invention is further configured to include a support base assembly, which includes support bases located on both sides, and a support rod slidably connected to the support base. The support rod passes through a roller and can move up and down to drive the roller to move synchronously.

[0009] The present invention is further configured such that the support base assembly is provided in two sets, and a plate is installed between the two support rods of the two support base assemblies. The plate can move up and down to drive the support rods to move synchronously.

[0010] The present invention is further configured such that the plate body includes an extension frame, the extension frame is provided with a groove three, a support rod is inserted into the groove three, and the upper and lower side walls of the groove three can abut against the outer wall of the support rod.

[0011] The present invention is further configured such that the support rod includes extension blocks located at both ends, the support base is provided with a groove, the extension blocks are inserted into the groove, and the extension blocks can move up and down along the inner wall of the groove.

[0012] The present invention is further configured such that the support base is also provided with a second groove, which is connected to the first groove.

[0013] In summary, this utility model has the following beneficial effects:

[0014] When the test is complete, the output end of drive component one slowly moves downward, and the hook at the bottom of the crane scale gradually retracts. Driven by drive component two, the rollers move upward, causing the connection between the inclined and straight sections to move upward, thus quickly relieving the tension on rope two. The hook at the bottom of the crane scale fully retracts, and the crane scale can be removed. Simultaneously, the operator can operate the test position on another crane scale. By setting up vertically movable rollers, the test time caused by the slow drive speed of drive component one is greatly reduced, improving test efficiency. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown, this embodiment discloses a crane scale testing device, including a fixed frame. The fixed frame includes a bottom plate 1 at the bottom and a top plate 11 at the top, which are fixedly connected to the bottom plate 1 by support columns. A driving component 3, which is a hydraulic cylinder, is installed on the top plate 11. A fixing device 4 is fixedly connected to the bottom output end of the driving component 3. The fixing device 4 can move up and down under the drive of the driving component 3. A tension sensor 5 is installed inside the fixing device 4. The tension sensor 5 is inserted into the fixing device 4. A limiting plate 41 is installed at the bottom of the fixing device 4 to limit the tension sensor 5. A rope 52 is connected to the bottom sensing end of the tension sensor 5. The rope 52 passes upward through the limiting plate 41 and is fixedly connected to the tension sensor 5.

[0021] When rope 52 is stretched, tension sensor 5 senses the tension generated by rope 52 and outputs it to the system. The lower end of rope 52 is used to connect to crane scale 51, which is an electronic crane scale and the component to be tested. The hook at the bottom of crane scale 51 is connected to rope 6, and the bottom of rope 6 is fixedly connected to a fixing seat 2. When drive component 3 drives the fixing device 4 to move upward, rope 52 and rope 6 become taut. As the traction force increases, the reading of crane scale 51 continuously increases, and at the same time, tension sensor 5 outputs the corresponding tension value. The crane scale 51 is then checked for compliance by comparison. Since the reading of tension sensor 5 is also affected by the weight of crane scale 51, when crane scale 51 is directly suspended below rope 52, the weight of crane scale 51 can be read and recorded.

[0022] like Figure 1 , Figure 3 As shown, a fixing seat 2 is installed on the upper end of the base plate 1. The fixing seat 2 includes a hook 21, and the hook 21 is connected to the rope body 6.

[0023] Combination Figures 1-3 The crane scale testing device also includes a support assembly 7, which includes support seats 71 located on both sides, with support rods 713 slidably connected to the support seats 71. Specifically, the support seats 71 are provided with a first groove 711 and a second groove 712, such as... Figure 3 As shown, the second groove 712 is arranged vertically along its length, and the second groove 712 penetrates the top of the support base 71. Figure 2As shown, the second groove 712 is connected to the first groove 711, and the second groove 712 penetrates the side wall of the support base 71. The support rod 713 passes through the second groove 712 and extends to another support base 71. The support rod 713 includes extension blocks 7131 at both ends. The extension blocks 7131 are inserted into the first groove 711 and can move up and down along the inner wall of the first groove 711. In the cross-section perpendicular to the axial direction of the support rod 713, the cross-sectional dimension of the second groove 712 is smaller than that of the first groove 711, and the cross-sectional dimension of the extension block 7131 matches that of the first groove 711.

[0024] Combination Figure 1 , Figure 2 As shown, the bracket assembly 7 is provided in two sets, and a plate 72 is installed between the two bracket rods 713 of the two bracket assemblies 7. Figure 1 In the middle, a second driving component 74 is installed on the upper end of the plate 72. The second driving component 74 is an electric cylinder. The second driving component 74 drives the plate 72 to move up and down, thereby driving the support rod 713 to move synchronously. The second driving component 74 is installed on the fixed plate 73, and the fixed plate 73 is fixedly installed on the top of the support base 71. Specifically, as Figure 2 , Figure 3 As shown, the plate 72 includes an extension frame 721, the extension frame 721 is provided with a groove 7211, a support rod 713 is inserted into the groove 7211, the upper and lower side walls of the groove 7211 can abut against the outer wall of the support rod 713, and one support rod 713 corresponds to two grooves 7211.

[0025] The left support rod 713 is equipped with a roller 714. The support rod 713 passes through the roller 714. The support rod 713 can move up and down to drive the roller 714 to move synchronously. The roller 714 can rotate along its own axis to reduce the resistance generated when the rope 6 abuts against the roller 714.

[0026] like Figure 1 As shown, roller 714 is located above fixed base 2 and to the left of fixed base 2. Rope 6 extends downward and to the right after passing around the left side of roller 714 to hook 21. Specifically, rope 6 includes a straight section and an inclined section 61 at the bottom. The upper end of the straight section is connected to the crane scale 51, and the lower end of the straight section is connected to the inclined section 61. One end of the inclined section 61 abuts against roller 714 (i.e., the point where it connects to the straight section), and the other end of the inclined section 61 is connected to hook 21. The inclined section 61 forms an obtuse angle with the straight section. During testing, roller 714 is at its lower limit position under the drive of drive component 74. The output end of drive component 3 moves upward, and rope 6 gradually tightens during the movement. The hook at the bottom of crane scale 51 is pulled downward to make crane scale 51 show a reading. When the test is finished, the output end of drive component 3 slowly moves downward, and the hook at the bottom of crane scale 51 gradually retracts. Figure 3As shown, at this time, the roller 714 moves upward under the drive of the second drive component 74, so that the connection between the inclined segment 61 and the straight segment moves upward, that is, the inclined segment 61 is inclined towards... Figure 3 The dotted L-shape quickly eliminates the tension of rope 6, allowing the hook at the bottom of the crane scale 51 to retract completely, enabling the crane scale 51 to be removed. Simultaneously, the operator can operate the detection position on another crane scale 51. By incorporating vertically movable rollers 714, the detection time caused by the slow drive speed of the drive component 3 is significantly reduced, improving detection efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
