Description

Technical Field

[0001] This utility model belongs to the field of safety testing technology, and in particular relates to a safety testing device for a hydraulic lifting platform. Background Technology

[0002] Hydraulic lifting platforms are multi-functional lifting and loading / unloading machinery. They are used for high-altitude operations and maintenance in factories, automated warehouses, parking lots, municipal works, docks, construction, decoration, logistics, power, transportation, petroleum, chemical, hotels, stadiums, mines, and other enterprises. To ensure the safety of hydraulic lifting platforms during subsequent use, they need to undergo safety testing after production.

[0003] Currently, the safety testing method for hydraulic platforms generally involves applying pressure to the platform and testing its stability under different pressures by changing the pressure intensity. However, the pressure point of the testing device is fixed, and the surface of the platform is not uniformly stressed during actual use. The platform may tilt or shake due to force deviation. Therefore, this method of safety testing is too idealistic and cannot guarantee the safe use of the lifting platform in the future. Utility Model Content

[0004] This utility model provides a safety testing device for a hydraulic lifting platform, which aims to solve the problem that the gantry frame is currently installed at a high position, making it inconvenient to inspect and disassemble.

[0005] This utility model is implemented as follows: a safety testing device for a hydraulic lifting platform includes a gantry frame; an electric cylinder is mounted on the top of the gantry frame via a fixed frame; a first pressure sensor is connected to the bottom of the output shaft of the electric cylinder; a fixed plate is connected to the bottom of the first pressure sensor; a sliding groove is formed inside the fixed plate, and a screw is installed in the sliding groove; a motor is mounted on the side of the fixed plate; the output shaft of the motor is connected to the end of the screw; a slider is slidably installed in the sliding groove of the fixed plate; a threaded groove is formed on the surface of the slider that matches the thread on the surface of the screw; a connecting frame is connected to the bottom of the slider; and a pressure block is installed on the lower side of the connecting frame.

[0006] Preferably, the pressure block is cylindrical and is rotatably mounted on the lower side of the connecting frame.

[0007] Preferably, a display screen is mounted on the surface of the first pressure sensor.

[0008] Preferably, electric telescopic plates are installed on both the left and right side walls of the gantry frame, and the output shaft of the electric telescopic plate consists of two long rods, with a second pressure sensor installed between the two long rods.

[0009] Preferably, a positioning sleeve is installed on the left side wall of the gantry frame, and a nozzle is installed on the front side of the positioning sleeve, with the nozzle facing the inside of the gantry frame.

[0010] Preferably, the positioning sleeve has a groove on its rear side, and a pull rod is slidably inserted into the groove. A locking block is installed at the inner end of the pull rod, and a spring is sleeved on the outside of the pull rod. The side wall of the gantry frame has slots that are adapted to the locking blocks, which are equidistantly opened from top to bottom. The locking blocks extend to the inner side of the positioning sleeve and are inserted into the slots of the gantry frame.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] This device uses an electric cylinder to apply pressure to a hydraulic platform with a pressure block. A first pressure sensor detects the output pressure of the electric cylinder in real time to obtain the pressure data of the platform. The pressure position of the pressure block can be adjusted by a screw and a slider. The device tests whether the top of the platform will tilt or sway under uneven force, thus making the platform test more comprehensive and improving the safety of subsequent platform use. A second pressure sensor can detect whether the platform generates lateral thrust during testing, and this setting can detect whether the platform will move horizontally under pressure.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a safety testing device for a hydraulic lifting platform, such as... Figure 1-4 As shown, the device includes a gantry frame 1. An electric cylinder 3 is mounted on the top of the gantry frame 1 via a fixing frame 2. A first pressure sensor 4 is connected to the bottom of the output shaft of the electric cylinder 3. A fixing plate 5 is connected to the bottom of the first pressure sensor 4. A sliding groove is formed inside the fixing plate 5, and a screw 6 is installed in the sliding groove. A motor 7 is mounted on the side of the fixing plate 5. The output shaft of the motor 7 is connected to the rod end of the screw 6. A slider 8 is slidably installed in the sliding groove of the fixing plate 5. A threaded groove matching the thread on the surface of the screw 6 is formed on the surface of the slider 8. A connecting frame 9 is connected to the bottom of the slider 8, and a pressure block 10 is installed on the lower side of the connecting frame 9. When using this device, the hydraulic lifting platform to be tested can be placed inside the gantry frame 1, and then the hydraulic lifting platform can be raised. At this time, the electric cylinder 3 is activated. The output shaft of the electric cylinder 3 drives the fixed plate 5 and the pressure block 10 to press down as a whole until the pressure block 10 contacts the surface of the platform. At this time, the output pressure of the electric cylinder 3 is detected in real time by the first pressure sensor 4 to obtain the pressure data of the platform. This setting is used to test the pressure resistance of the platform. During the test, the motor 7 can be activated. The motor 7 drives the screw 6 to rotate, and the slider 8 moves horizontally under the drive of the screw 6, which can drive the pressure block 10 to move horizontally. This setting allows the pressure block 10 to be placed at different positions on the platform surface to apply pressure. It tests whether the top of the platform will tilt or shake under uneven force, so as to make the platform test more comprehensive and improve the safety of subsequent platform use.

[0021] The pressure block 10 is cylindrical and is rotatably mounted on the lower side of the connecting frame 9. By setting the pressure block 10 to a cylindrical shape, this setting allows the pressure block 10 to move smoothly on the surface of the platform while applying pressure, instead of having to reapply pressure at each position. This setting makes the test data more accurate.

[0022] A display screen is mounted on the surface of the first pressure sensor 4. By mounting a display screen on the surface of the first pressure sensor 4, pressure data can be displayed, making it easier to view the pressure level of the platform in real time.

[0023] Electric telescopic plates 12 are installed on both the left and right side walls of the gantry frame 1. The output shaft of the electric telescopic plate 12 consists of two long rods, and a second pressure sensor 11 is installed between the two long rods. By setting up the electric telescopic plate 12 and the second pressure sensor 11, the electric telescopic plate 12 can be activated to position the platform after it is placed, so as to prevent the platform from moving due to high pressure during the test. By installing the second pressure sensor 11 on the output rod of the electric telescopic plate 12, it is possible to detect whether the platform generates lateral thrust during the test. This setting can detect whether the platform will move horizontally when under pressure, so as to ensure the safety and reliability of the platform in subsequent use.

[0024] A positioning sleeve 13 is installed on the left side wall of the gantry frame 1. A nozzle 14 is installed on the front side of the positioning sleeve 13, with the nozzle 14 facing the inside of the gantry frame 1. By setting the nozzle 14, the platform can be sprayed by activating the nozzle 14 during testing. This setting can be used to test whether the hydraulic device and lifting mechanism of the platform can operate normally in a humid environment.

[0025] The positioning sleeve 13 has a groove on its rear side, and a pull rod 15 is slidably inserted into the groove. A locking block 16 is installed on the inner end of the pull rod 15, and a spring 17 is sleeved on the outside of the pull rod 15. The side wall of the gantry frame 1 has slots that are adapted to the locking block 16, which are evenly spaced from top to bottom. The locking block 16 extends to the inner side of the positioning sleeve 13 and is inserted into the slot of the gantry frame 1. By setting the positioning sleeve 13, the pull rod 15 on the rear side of the positioning sleeve 13 can be pulled to pull the locking block 16 out of the slot on the surface of the gantry frame 1. Then the spraying height of the nozzle 14 can be adjusted according to different platforms. This setting can improve the applicability of the nozzle 14.
