Description

Technical Field

[0001] The utility model relates to the technical field of special equipment detection, in particular to a forklift arm load detection device with convenient load adjustment. Background Art

[0002] Special equipment refers to equipment that poses a greater risk to personal and property safety during production, operation and use, such as pressure vessels, boilers, lifting machinery, elevators, pressure pipelines, passenger ropeways, large amusement facilities and special motor vehicles within the site (factory). Special equipment testing is the process of regular or irregular inspection, testing and evaluation of special equipment to ensure its safe operation and compliance with relevant laws, regulations, standards and technical requirements.

[0003] Patent document with application number 202323234302.9 discloses a load detection device for a multi-stage forklift gantry, including a workbench, a support plate fixedly connected to the left upper end of the workbench, a connecting plate fixedly connected to the upper left end of the support plate, and mounting plates fixedly connected to the front and rear ends of the support plate.

[0004] However, traditional forklift arm load detection equipment is mostly only adjusted for the load when in use, and cannot accurately detect the dynamically lifted forklift arm. Therefore, there is an urgent need for a forklift arm load detection device that can easily adjust the load to solve the above problem.

[0005] For example, the load-bearing capacity of some goods picked up by forklifts in static state is different from that in dynamic state during the lifting process. Traditional detection equipment cannot effectively cope with the dynamic detection process. Utility Model Content

[0006] The utility model discloses a forklift arm load detection device with convenient load adjustment, aiming to solve the technical problem that traditional forklift arm load detection devices, when in use, are mostly only adjusted for the load but cannot accurately detect the dynamically lifted forklift arm.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A forklift arm load detection device with convenient load adjustment includes a vehicle body and a lifting frame installed on the vehicle body, the lifting frame is provided with a forklift arm body, and also includes: an adjustment mechanism: the adjustment mechanism includes vertical rods arranged on the outer walls of both sides of the lifting frame, an adjustment groove is opened on the outer wall of one side of the vertical rod, a threaded rod is connected to the inner wall of the adjustment groove through a bearing, a threaded block is provided on the outer wall of the threaded rod, a motor is provided at the bottom end of the vertical rod, and the output end of the motor is connected to the bottom end of the threaded rod; an angle detection mechanism: the angle detection mechanism includes a detection rod arranged on the adjustment mechanism, and four angle measuring components are provided on the detection rod; a limiting mechanism: the limiting mechanism is arranged at the connection between the threaded block and the detection rod.

[0009] In this solution, the adjustment mechanism is set up to drive the threaded rod to rotate under the drive of the motor, so that the threaded block connected to the outer wall of the threaded rod drives the detection rod on the angle detection mechanism to adjust the lifting and lowering of the forklift arm body synchronously, which makes it convenient for the angle measuring component to detect the forklift arm body during the dynamic lifting process. During this process, loads of different weights can be hung on the forklift arm body in turn to repeat the test multiple times to ensure the accuracy of the test results.

[0010] In a preferred solution, the limiting mechanism includes a sleeve arranged on the threaded block, the detection rod is connected to the outer wall of one side of the threaded block by a hinge, a limiting sleeve is provided on the outer wall of one side of the detection rod, notches are provided on the outer walls on both sides of the limiting sleeve, a limiting rod is slidably connected to the inner wall of the limiting sleeve, and protrusions are provided on the outer walls on both sides of the limiting rod.

[0011] When the detection is not carried out, the limit mechanism does not start to work, and the detection rod will remain flush with the vertical rod due to the action of the hinge connection. When the detection rod is used, it is lifted to be perpendicular to the vertical rod. At this time, the limit mechanism starts to work, and the angle measurement component on the detection rod begins to perform load detection on the forklift arm body.

[0012] As can be seen from the above, a forklift arm load detection device that is convenient for adjusting the load comprises a vehicle body and a lifting frame mounted on the vehicle body, the lifting frame being provided with a forklift arm body, and further comprising: an adjustment mechanism: the adjustment mechanism comprises a vertical rod arranged on the outer walls of both sides of the lifting frame, an adjustment slot being provided on the outer wall of one side of the vertical rod, a threaded rod being connected to the inner wall of the adjustment slot via a bearing, a threaded block being provided on the outer wall of the threaded rod, a motor being provided at the bottom end of the vertical rod, and an output end of the motor being connected to the bottom end of the threaded rod; an angle detection mechanism: the angle detection mechanism comprises a detection rod arranged on the adjustment mechanism, four angle measurement components being provided on the detection rod; a limiting mechanism: the limiting mechanism being provided at the connection between the threaded block and the detection rod. The forklift arm load detection device that is convenient for adjusting the load provided by the utility model has the technical effect of improving the flexibility of the detection method and achieving effective load detection during the dynamic lifting process of the forklift arm body.

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0019] The utility model discloses a forklift arm load detection device with convenient load adjustment, which is mainly used in scenarios where traditional forklift arm load detection devices, when in use, mostly only adjust the load but cannot accurately detect the dynamically lifted forklift arm.

[0020] Reference Figure 1 、 Figure 2 and Figure 3 A forklift arm load detection device with convenient load adjustment includes a vehicle body 1 and a lifting frame 2 installed on the vehicle body 1, a forklift arm body 4 is installed on the lifting frame 2, and also includes: an adjusting mechanism: the adjusting mechanism includes a vertical rod 3 arranged on the outer walls of both sides of the lifting frame 2, an adjusting groove is opened on the outer wall of one side of the vertical rod 3, a threaded rod 8 is connected to the inner wall of the adjusting groove through a bearing, a threaded block 10 is provided on the outer wall of the threaded rod 8, a motor 5 is provided at the bottom end of the vertical rod 3, and the output end of the motor 5 is connected to the bottom end of the threaded rod 8; an angle detection mechanism: the angle detection mechanism includes a detection rod 6 arranged on the adjusting mechanism, and four angle measuring components 7 are provided on the detection rod 6; a limiting mechanism: the limiting mechanism is arranged at the connection between the threaded block 10 and the detection rod 6.

[0021] In this solution, the adjustment mechanism is set up, and the threaded rod 8 can be driven to rotate under the driving action of the motor 5, so that the threaded block 10 connected to the outer wall of the threaded rod 8 drives the detection rod 6 on the angle detection mechanism to adjust the rise and fall of the forklift arm body 4 synchronously, so that the angle measuring component 7 can be convenient for detecting the forklift arm body 4 during the dynamic lifting process. During this process, loads of different weights can be hung on the forklift arm body 4 in turn to repeat the test multiple times to ensure the accuracy of the test results.

[0022] Among them, four blocks 9 are slidably connected to the outer wall of the detection rod 6, and four angle measuring components 7 are respectively connected to one side of the four blocks 9. By sliding the blocks 9, the four angle measuring components 7 can be driven to be distributed at different intervals to ensure multi-directional detection of the load condition of the forklift arm body 4.

[0023] Among them, the vertical rod 3 and the lifting frame 2 are located on the same vertical plane. When the lifting frame 2 is affected by the load-bearing effect of the forklift arm body 4, the vertical rod 3 will also be affected, thereby ensuring that the set detection rod 6 always maintains a 90-degree detection angle with the vertical rod 3 and the lifting frame 2, avoiding the impact of the load condition of the forklift arm body 4 on the detection.

[0024] Reference Figure 3 and Figure 4 In a preferred embodiment, the limiting mechanism includes a sleeve 13 arranged on the threaded block 10, the detection rod 6 is connected to the outer wall of one side of the threaded block 10 by a hinge, a limiting sleeve 11 is provided on the outer wall of one side of the detection rod 6, and notches are provided on the outer walls on both sides of the limiting sleeve 11. A limiting rod 12 is slidably connected to the inner wall of the limiting sleeve 11, and protrusions are provided on the outer walls on both sides of the limiting rod 12.

[0025] Specifically, when the detection is not performed, the limit mechanism does not start to work, and the detection rod 6 will remain flush with the vertical rod 3 under the action of the hinge connection. When the detection rod 6 is to be used, the detection rod 6 is lifted to be perpendicular to the vertical rod 3. At this time, the limit mechanism starts to work, and the angle measuring component 7 on the detection rod 6 starts to perform load detection on the forklift arm body 4.

[0026] Among them, the two protrusions are respectively matched with the two notches. By utilizing the mutual restriction of the protrusions and the notches, the limiting rod 12 will not be separated from the limiting sleeve 11 when the detection rod 6 is not working, thereby maintaining the stability of the limiting mechanism itself.

[0027] The limiting rod 12 is matched with the inner wall of the sleeve 13 .

[0028] Working principle: When in use, first select the counterweight required for load detection, and then perform a step-by-step hanging test by hanging the forklift arm body 4. At the same time, lift the detection rod 6 to be perpendicular to the vertical rod 3, and use the limit plug rod 12 on the limit mechanism to cooperate with the limit sleeve 11 and the plug sleeve 13 to limit the detection rod 6. After the limitation is completed, start the motor 5 and keep the speed of the motor 5 driving the threaded rod 8 to drive the detection rod 6 to rise and fall at the same speed as the forklift arm body 4, so as to use the angle measuring component 7 to perform load detection on the forklift arm body 4 at the same height.

[0029] It should be noted that, as the detection rod 6 and the forklift arm body 4 are raised and lowered synchronously, the actual process is recorded by a probe (not shown in the figure). After recording, the data will be transmitted to the computer for unified organization, and finally the specific load detection result will be obtained based on the detection data.

[0030] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
