Description

Technical Field

[0001] This utility model belongs to the field of electric cylinder load testing technology, and specifically relates to a load testing device for boom electric cylinder. Background Technology

[0002] The boom electric cylinder load testing equipment is mainly used to test and verify the performance of boom electric cylinders under different load conditions, including their load-bearing capacity, stability, and durability. This equipment usually consists of one or more boom electric cylinders installed between two components that can be hinged and rotated. By controlling the extension and retraction of the electric cylinders, the load conditions in actual work are simulated to achieve the load test of the boom electric cylinders.

[0003] Existing boom electric cylinder load testing equipment installs the boom electric cylinder between two hinged rotating parts. By controlling the extension and retraction of the boom electric cylinder, a counterweight on the test platform located on the upper rotating part is lifted, thereby achieving the load test of the boom electric cylinder. Since the weight of each counterweight is fixed, the number of counterweights can be adjusted to achieve load testing of boom electric cylinders of various specifications. However, the installation of the counterweights usually involves inserting them into bolt posts and installing them with bolts. Each time a counterweight plate is added or removed, tools (such as wrenches) are needed to tighten or loosen the bolts. This not only increases the operation time but also makes the adjustment process cumbersome. Because bolts need to be installed or removed one by one, especially when conducting multiple tests with different weight configurations, the overall efficiency is low, affecting the test progress. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a boom electric cylinder load testing device that allows for quick disassembly and installation of counterweights without the need for external tools, simply by pulling the pull plate. This simplifies the installation and disassembly process of the counterweights, significantly reduces preparation time, improves overall work efficiency, and enables the test to proceed more quickly.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a load testing device for a boom electric cylinder, including a bearing plate, a rotating support plate is provided on the upper left side of the bearing plate, a test platform is rotatably arranged inside the rotating support plate, a docking plate is provided on the upper right side of the bearing plate and opposite to the right side of the test platform, a lower rotating component and an upper rotating component are respectively provided on the upper end of the bearing plate and the lower end of the test platform, a counterweight mechanism that can be quickly disassembled is provided on the upper end of the bearing plate, the counterweight mechanism that can be quickly disassembled includes a sliding plate slidably arranged on the upper part of the test platform, a plurality of docking slot frames are provided on the right side of the sliding plate, the plurality of docking slot frames are arranged at equal intervals, a counterweight plate is slidably arranged inside the two docking slot frames located at the bottom, a connecting plate is provided between the front and rear sides of the sliding plate, a limit baffle is slidably arranged inside the connecting plate, the limit baffle abuts against the two counterweight plates, and an elastic drive unit is provided between the baffle and the connecting plate.

[0006] The elastic drive unit includes two sliding columns disposed between the baffle and the connecting plate. The two sliding columns are slidably connected to the connecting plate and are positioned in a corresponding manner. Two springs are disposed between the baffle and the connecting plate and are respectively sleeved on the outer arc surface of the corresponding sliding columns.

[0007] As a further improvement of this utility model, an electric push rod is provided at the upper end of the bearing plate, and the telescopic end of the electric push rod is connected to the left side of the sliding plate.

[0008] As a further improvement of this utility model, a controller is provided at the upper end of the support plate, and the electric push rod is electrically connected to the control panel.

[0009] As a further improvement of this utility model, a pull plate is provided at the upper right side of the limiting baffle, and the pull plate is located in the middle of the limiting baffle.

[0010] As a further improvement of this utility model, a support mounting bracket is provided at the lower end of the bearing plate, and multiple mounting holes are respectively opened at the four corners of the support mounting bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Firstly, by controlling the operation of the boom electric cylinder and the movement of the telescopic end, in conjunction with the rotation of the lower and upper rotating parts, the counterweight mechanism on the test bench, which can be quickly disassembled and assembled, lifts the counterweight plate on the test bench and rotates it upward under the rotation of the rotating support plate, thereby quickly realizing the load test of the boom electric cylinder.

[0013] Secondly, by pulling the pull plate upwards, the limiting baffle moves upwards under the sliding restriction of the connecting plate and the guiding sliding relationship of the sliding column, causing it to move away from the right side of the docking slot frame. Then, personnel can slide the counterweight plate out from inside the docking slot frame or add a new counterweight plate. Afterwards, personnel release the pull plate to limit the counterweight plate inside the docking slot frame, preventing it from slipping or falling off during the load test. The counterweight can be quickly disassembled and installed without the need for external tools, simply by pulling the pull plate. This simplifies the installation and disassembly process of the counterweight, significantly reduces preparation time, improves overall work efficiency, and allows the test to proceed more quickly.

[0014] Third, the electric push rod is opened by the controller, and the telescopic end can drive the counterweight plate on the sliding plate to move left and right under the restriction of the slide groove of the test bench. Thus, without changing the number of counterweight plates, the load torque can be changed to meet the load test requirements of the boom electric cylinder, making the test equipment more flexible when conducting load tests on the boom electric cylinder.

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 3 As shown, a load testing device for a boom electric cylinder includes a bearing plate 101. A rotating support plate 103 is provided on the upper left side of the bearing plate 101. A test platform 105 is rotatably arranged inside the rotating support plate 103. A docking plate 104 is provided on the upper right side of the bearing plate 101, which is opposite to the right side of the test platform 105. A lower rotating component 107 and an upper rotating component 108 are respectively provided on the upper end of the bearing plate 101 and the lower end of the test platform 105. A counterweight mechanism that can be quickly disassembled and assembled is provided on the upper end of the bearing plate 101. An electric push rod 106 is provided on the upper end of the bearing plate 101. The telescopic end of the electric push rod 106 is connected to the left side of the sliding plate 201.

[0023] like Figure 2 , 4 As shown, the quick-disassembly counterweight mechanism includes a sliding plate 201 slidably mounted on the upper end of the test bench 105. Multiple docking slots 208 are provided on the right side of the sliding plate 201. Counterweight plates 206 are slidably mounted inside the two lowest docking slots 208. A connecting plate 202 is provided between the front and rear sides of the sliding plate 201. The sliding plate 201 and the connecting plate 202 are fixed together by welding. A limiting baffle 205 is slidably mounted inside the connecting plate 202, abutting against the two counterweight plates 206. An elastic drive unit is provided between the baffle and the connecting plate 202. The elastic drive unit includes two sliding columns 203 positioned between the baffle and the connecting plate 202, slidably connected to the connecting plate 202. Two springs 204 are positioned between the baffle and the connecting plate 202, each spring being sleeved on the outer arc surface of its corresponding sliding column 203.

[0024] like Figure 1 As shown, a controller 301 is provided at the upper end of the support plate 101, and the electric push rod 106 is electrically connected to the control panel.

[0025] like Figure 2 , 4 As shown, a pull plate 207 is provided on the upper right side of the limiting baffle 205, and the limiting baffle 205 and the pull plate 207 are fixed together by welding.

[0026] First, the left end of the boom electric cylinder to be tested is bolted to the lower rotating part 107. Then, the telescopic end of the boom electric cylinder is installed to the upper rotating part 108. Subsequently, by controlling the operation of the boom electric cylinder, the telescopic end moves. In conjunction with the rotation of the lower rotating part 107 and the upper rotating part 108, the counterweight mechanism on the test bench 105, which can be quickly disassembled and installed, lifts the counterweight plate 206 on the test bench 105 and rotates it upward under the rotation of the rotating support plate 103. Since the weight of the counterweight plate 206 is known, it can be determined whether the load of the boom electric cylinder meets the requirements. After the load test is completed, the boom electric cylinder is controlled to reset, and the test bench 105 will rotate downward into the interior of the docking plate 104 to support the test bench 105.

[0027] When it is necessary to replace the boom electric cylinder of different specifications for load testing, and when the counterweight plate 206 needs to be replaced, by pulling the pull plate 207 upward, the limiting baffle 205 moves upward under the sliding restriction of the connecting plate 202 and the guiding sliding relationship of the sliding column 203, so that it moves away from the right side of the docking slot frame 208. At this time, the spring 204 is in a compressed state. Then, the personnel can slide the counterweight plate 206 out of the docking slot frame 208 or add a new counterweight plate 206. Then, the personnel release the pull plate 207. At this time, the spring 204 quickly rebounds, causing the limiting baffle 205 to reset, limiting the counterweight plate 206 inside the docking slot frame 208, and preventing it from slipping or falling during the load test (especially in the case of failure of the boom electric cylinder load test).

[0028] Furthermore, personnel can control the operation of the electric push rod 106 via the controller 301. The telescopic end can drive the counterweight plate 206 on the sliding plate 201 to move left and right under the restriction of the slide groove of the test bench 105. Thus, without changing the number of counterweight plates 206, the load torque can be changed to meet the load test requirements of the boom electric cylinder.

[0029] According to another embodiment of the present invention, such as Figure 1 As shown, a support mounting bracket 102 is provided at the lower end of the bearing plate 101. The bearing plate 101 and the mounting bracket are fixed together by welding. Multiple mounting holes are opened at the four corners of the support mounting bracket 102. The test equipment can be fixed on the ground by using the mounting holes inside the support mounting bracket 102 and mounting bolts, thereby realizing the fixed installation of the test equipment and ensuring the stability of the boom electric cylinder load test.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
