Description

Technical Field

[0001] This invention relates to the field of loading device technology, specifically a large-scale fixed loading system. Background Technology

[0002] Loading test equipment is the basic platform for various tests. With the development of products, there are higher requirements for loading test equipment. Products are becoming more family-oriented and serialized, and their external dimensions are also showing a trend of serialization. Loading test equipment needs to provide sufficient test space to meet the test needs of product serialization. At the same time, loading test equipment also needs to improve the working efficiency of the test as much as possible through reasonable mechanical structure settings.

[0003] Most existing loading devices use a fixed, integrated frame platform. The loading platform is fixed to a lower (suitable) plane, and the main body is generally a fixed frame structure. The workpiece is placed inside the loading platform by manpower or machinery and then fixed with tooling before loading experiments are conducted. This type of testing device has significant limitations, requiring separate testing tooling for each workpiece, resulting in low testing efficiency.

[0004] Currently, most large-scale loading test equipment has a platform at the bottom and a fixed loading device at the top. The installation cycle of the workpiece during the test is long and the adjustment is difficult. Since the fixed loading device is usually installed at the top, hoisting is hindered and loading and unloading are difficult, which greatly affects the overall working efficiency of the test bench.

[0005] The present invention addresses the above problems by setting a moving device on the test platform at the bottom of the loading device. When the test workpiece needs to be loaded or unloaded, the platform can be moved to the top of the loading device range, thus solving the problem of quick hoisting of the workpiece. The upper liftable loading device platform has a locking function, which can realize the height adjustment and can be locked at a suitable position to ensure the fixation and support required during the loading experiment. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a large-scale fixed loading system with advantages such as rapid workpiece hoisting. It solves the problems of long installation cycles and difficult adjustments during workpiece testing, as well as the difficulty in hoisting and unloading due to the fixed loading device being generally installed at the top, which greatly affects the overall working efficiency of the test bench.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a large fixed loading system, including a bed, two columns on the ground on both sides of the bed, a horizontal top cover fixed to the top of the four columns, crossbeams slidably connected to the columns on the front and rear sides, a horizontal lifting platform fixed to the lower surface of the two crossbeams, and a sliding table slidably connected to the bed.

[0008] The bed is equipped with a horizontal moving mechanism for driving the slide to move, and the top cover is equipped with a longitudinal moving mechanism for driving the lifting platform to rise and fall.

[0009] Furthermore, the horizontal moving mechanism includes a motor a fixed to the right side of the bed, the output shaft of the motor a passing through and extending into the bed and fixed with a screw a, and a horizontal slide block threaded to the outer side of the screw a, the horizontal slide block being fixed to the slide table.

[0010] Furthermore, the front and rear sides of the upper surface of the bed have two linear protrusions a, and the slide moves linearly left and right on the outside of the protrusions a.

[0011] Furthermore, the four columns are arranged in a rectangular shape, and the opposite sides of the columns on the left and right sides protrude to form protrusions b. The two crossbeams are slidably connected to the two protrusions b respectively, and move linearly up and down.

[0012] Furthermore, the longitudinal moving mechanism includes a motor b fixed to the upper surface of the top cover. The output shaft of the motor b is connected to two horizontally oriented drive rods via a connector. The upper surface of the top cover is rotatably connected to two screws b via bearings. The bottom end of the screws b passes through and extends to the lower side of the top cover, and the lifting platform is threadedly connected to the screws b.

[0013] Furthermore, the connecting member includes a housing, a gear a, and a gear b. The housing is fixed to the upper surface of the top cover. The output shaft of the motor b passes through and extends into the housing and is fixed to the gear a. Both gears b mesh with the gear a, and the two drive rods are respectively fixed in the shaft holes of the gears b.

[0014] Furthermore, the bed is provided with a first hydraulic locking device for locking the brake when the motor a stops running, and the housing is provided with a second hydraulic locking device for locking the brake when the motor b stops running. The four columns are respectively fixed to the front and rear sides of the bed.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This large-scale fixed loading system was developed primarily to address the loading test requirements of large workpieces. It can accommodate workpieces with dimensions of up to 2m × 2m × 4m, and its height is continuously adjustable from 0 to 4m. The upper part of the loading test device is adjustable to the height of the test piece and features a reliable locking function to ensure the workpiece and tooling are in the most suitable condition for testing. Simultaneously, the loading platform at the bottom of the device is a high-precision moving platform, improving the efficiency of workpiece clamping preparation before testing and disassembly after testing. By setting a moving device on the bottom test platform, the platform can be moved to the top of the loading device area when the workpiece needs to be loaded or unloaded, solving the problem of rapid workpiece hoisting. The upper, liftable loading platform has a locking function, allowing for height adjustment and locking at appropriate positions to ensure the necessary fixation and support during loading tests.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-3The large fixed loading system in this embodiment includes a bed 1, two columns 2 on the ground on both sides of the bed 1, a horizontal top cover 3 fixed to the top of the four columns 2, crossbeams 7 slidably connected to the front and rear columns 2, a horizontal lifting platform 6 fixed to the lower surface of the two crossbeams 7, and a sliding table 4 slidably connected to the bed 1.

[0025] The bed 1 is equipped with a horizontal moving mechanism 5 for driving the slide 4 to move, and the top cover 3 is equipped with a longitudinal moving mechanism 8 for driving the lifting platform 6 to rise and fall.

[0026] In this embodiment, the front and rear sides of the upper surface of the bed 1 both protrude to form two linear protrusions a9. The slide table 4 moves linearly left and right on the outside of the protrusions a9. The four columns 2 are distributed in a rectangle, and the opposite sides of the left and right columns 2 both protrude to form protrusions b10. The two crossbeams 7 are slidably connected to the two protrusions b10 respectively, and move linearly up and down.

[0027] Please see Figure 4 In order to drive the slide table 4 to move, the horizontal moving mechanism 5 in this embodiment includes a motor a501 fixed to the right side of the bed 1. The output shaft of the motor a501 passes through and extends into the bed 1 and is fixed with a screw a502. The outer side of the screw a502 is threadedly connected to a horizontal slide 503. The horizontal slide 503 is fixed to the slide table 4. During the loading experiment, the slide table 4 rotates when the output shaft of the motor a501 rotates, which in turn rotates the screw a502. At this time, the horizontal slide 503 on its outer side slides, further moving the slide table 4 horizontally. During the movement of the slide table 4, it is positioned by the protrusion a9 to improve its stability during the movement.

[0028] In this embodiment, when the slide table 4 moves horizontally to the outside of the bed 1, the test piece can be conveniently placed on the slide table 4 using a hoisting tool or other convenient means. After the test piece is placed, the slide table 4 moves to the loading position of the bed 1 by the operation of the motor a501, and then the motor a501 is locked by the first hydraulic locking component to further lock the slide table 4 to ensure the stability of the slide table 4.

[0029] Please see Figure 5To drive the lifting platform 6 to rise and fall, the longitudinal moving mechanism 8 in this embodiment includes a motor b801 fixed to the upper surface of the top cover 3. The output shaft of the motor b801 is connected to two horizontally oriented drive rods 802 via a connecting member. The upper surface of the top cover 3 is rotatably connected to two screws b803 via bearings. The bottom end of the screws b803 passes through and extends to the lower side of the top cover 3. The lifting platform 6 is threadedly connected to the screws b803. When the output shaft of the motor b801 rotates, it drives the gear b through gear a to rotate, which in turn drives the drive rods 802 on both sides to rotate. The drive rods 802 on both sides drive the two screws b803 to rotate, causing the lifting platform 6, which is threadedly connected to its outer side, to move. The lifting platform 6 is fixed to the crossbeam 7, and the crossbeam 7 is positioned by the protrusion b10 to improve its stability during vertical movement. After the height of the lifting platform 6 is adjusted, it is locked using a second hydraulic locking member to ensure the stability of the lifting platform 6, and then the test can be carried out.

[0030] In this embodiment, the connector includes a housing, a gear a, and a gear b. The housing is fixed to the upper surface of the top cover 3. The output shaft of the motor b801 passes through and extends into the housing and is fixed to the gear a. Both gears b mesh with the gear a, and the two drive rods 802 are respectively fixed in the shaft holes of the gears b.

[0031] The screw b803 and the drive rod 802 are also driven by gears, and when the motor b801 is running, it can drive the screws b803 on both sides to rotate.

[0032] The bed 1 is equipped with a first hydraulic locking device for locking the brake when the motor a501 stops running, and the housing is equipped with a second hydraulic locking device for locking the brake when the motor b801 stops running. The four columns 2 are fixed to the front and rear sides of the bed 1 respectively. The hydraulic locking device is prior art and will not be described in detail in this application.

[0033] The working principle of the above embodiment is as follows: During the loading experiment, the slide table 4, driven by the operation of motor a501, rotates its output shaft, which in turn rotates the screw a502. This, in turn, causes the outer horizontal slide block 503 to slide, further moving the slide table 4 horizontally. During this movement, the slide table 4 is positioned by the protrusion a9 to improve its stability. When the slide table 4 moves horizontally to the outside of the bed 1, the test piece can be easily placed on the slide table 4 using lifting tools or other convenient methods. After the test piece is placed, the slide table 4, driven by motor a501, moves to the loading position of the bed 1, and then is stopped by the first hydraulic locking component. The motor a501 is locked, further locking the slide table 4 to ensure its stability. When the output shaft of the motor b801 rotates, it drives gear b via gear a, which in turn drives the drive rods 802 on both sides. These drive rods 802 then drive the two screws b803 to rotate, causing the lifting platform 6, which is threaded to its outer side, to move. The lifting platform 6 is fixed to the crossbeam 7, and the crossbeam 7 is positioned by the protrusion b10 to improve its stability during vertical movement. After the height of the lifting platform 6 is adjusted, it is locked using the second hydraulic locking device to ensure its stability before testing.
