Technical Field

[0001] The utility model relates to the technical field of load boxes, in particular to a movable load box for testing generator sets. Background Technique

[0002] The load box for testing generator sets is a device used to simulate loads to test the performance of generator sets. It is usually designed to be connected to the output port of the generator set, and various electrical loads are used to simulate the power demand under actual use conditions. The load box plays an important role in the research, manufacturing and maintenance processes of generator sets, ensuring that the generator set can operate reliably under various working conditions, and also helping to debug and optimize the design and control system of the generator set.

[0003] At present, most of the existing movable load boxes for testing generator sets have a simple external structure. Universal wheels are installed at the bottom corners, and the position of the whole load box is adjusted by pushing the box body. However, after adjustment, the position of the box body cannot be turned and fixed, and at the same time, when pushing, the box body moves with an offset phenomenon. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a movable load box for testing generator sets, which has the advantages of being able to turn and fix the position of the box body, ensuring the stability of the movement adjustment of the box body, and avoiding the offset phenomenon, etc., and solves the problems that the external structure of the current load box is simple, the adjusted angle cannot be turned and fixed, and there is an offset when pushing.

[0005] To achieve the above object, the utility model provides the following technical solution: A movable load box for testing generator sets, including a box body assembly, a supporting assembly and a stabilizing assembly. The box body assembly includes a plurality of connecting corners, on which a vertical stabilizing rod and a horizontal stabilizing rod are movably connected, and the vertical stabilizing rod and the horizontal stabilizing rod are perpendicular to each other. At the same time, a protective plate and a side plate are fixed between the vertical and horizontal stabilizing rods, and the protective plate and the side plate are perpendicular to each other. The box body assembly uses eight connecting corners, and the horizontal directions between the eight connecting corners are connected by horizontal stabilizing rods, while the vertical directions are connected by vertical stabilizing rods to form the frame structure of the box body, and a protective plate and a side plate are installed in the frame to form the whole load box, which can provide protection for the internal equipment of the box body.

[0006] The supporting assembly includes a supporting plate fixed to the bottom of the box assembly, a first electric telescopic rod is fixed to the bottom of the supporting plate, a mounting plate is movably hinged at the output end of the first electric telescopic rod, a moving wheel is fixed on the mounting plate, and an adjusting telescopic rod is fixed to the bottom of the supporting plate, a connecting block is movably hinged at the output end of the adjusting telescopic rod, the supporting plate is used to provide support for the box assembly, and the first electric telescopic rod is installed at the four angular positions of the bottom of the supporting plate, and a moving wheel is installed at the bottom of the first electric telescopic rod through the mounting plate, so that the moving wheel can rotate and move according to the pushed direction, so as to adjust the position of the box assembly, and at the same time, the output end of the adjusting telescopic rod is moved downward, so as to make the bottom of the stabilizing assembly fit to the ground, and the angle of the stabilizing assembly can be adjusted by rotating the connecting block.

[0007] The stabilizing component includes a stabilizing base plate movably connected to the bottom of the supporting plate, a stabilizing slide rail is fixed on the stabilizing base plate and along its length direction, a connecting block is slidably connected in the stabilizing slide rail, and when the bottom of the stabilizing base plate is close to the ground, the connecting block slides in the stabilizing slide rail, so that the box assembly can move along the direction of the stabilizing slide rail, thereby improving the stability of position adjustment.

[0008] When the load box for testing the generator set is moved and adjusted in position, the box assembly is pushed to make the moving wheel at the bottom rotate in the pushed direction to realize the movement of the overall position of the device. When it moves to the approximate position, the box assembly is stopped from being pushed, and the connecting block and the stable bottom plate are rotated to the required adjustment position by toggling the stable bottom plate. At this time, the output end of the telescopic rod is controlled to move downward so that the stable bottom plate is close to the ground at this angle. At this time, the suction cup can be tightly adsorbed on the flat ground by controlling the suction cup, or the output end of the electric cylinder is controlled to move downward so that the bottom of the positioning fork is close to the ground to ensure the stability of the stable bottom plate. At this time, the box assembly is pushed to make the connecting block slide in the stable slide rail, so that the box assembly is translated along the angle of the stable assembly. After the position adjustment is completed, the output end of the second electric telescopic rod is controlled to output downward so that the positioning rod is close to the ground to fix the position.

[0009] As a further improvement of the above solution, the sides of the vertical stabilizing rod and the horizontal stabilizing rod are provided with mounting convex strips along their length direction, and the mounting convex strips are clamped in the protective plate and the side plate.

[0010] Through the above technical scheme, the sides of the protective plate and the side panels are provided with strip grooves that match the sides of the installation convex strips according to the length and height of the corresponding vertical stabilizing rods and the horizontal stabilizing rods. The installation convex strips are movably sleeved in the strip grooves of the protective plate and the side panels, thereby improving the stability of the installation and preventing the protective plate and the side panels from being separated from the vertical and horizontal stabilizing rods.

[0011] As a further improvement of the above solution, rotation buttons are movably hinged at both ends of the vertical stabilizing rod and the horizontal stabilizing rod, and a fixing screw rod is fixed inside the rotation button, and one end of the fixing screw rod is threadedly connected inside the connecting corner.

[0012] Through the above technical solution, the connecting corner has corners in three directions and can be connected to the vertical and horizontal stabilizing rods. By rotating the rotation button, the fixing screw rod is threadedly connected inside the corresponding end of the connecting corner, realizing the convenience and stability of the connection between the vertical and horizontal rods.

[0013] As a further improvement of the above solution, positioning screw rods are threadedly connected to the sides of the vertical stabilizing rod and the horizontal stabilizing rod, and the output ends of the positioning screw rods are attached to the sides of the fixing screw rod.

[0014] Through the above technical solution, the rotation button is fixed in the middle of the fixing screw rod, so that one end of the fixing screw rod is inside the vertical and horizontal stabilizing rods, and the other end is outside and can be inserted into the connecting corner. By rotating the positioning screw rod clockwise, the front end of the positioning screw rod is closely attached to the side of the fixing screw rod, realizing the fixation of the fixing screw rod, improving the connection stability, and preventing the fixing screw rod from freely rotating, resulting in the vertical and horizontal stabilizing rods detaching from the connecting corner.

[0015] As a further improvement of the above solution, a second electric telescopic rod is fixed to the bottom of the supporting plate, and a positioning rod is fixed to the output end of the second electric telescopic rod.

[0016] Through the above technical solution, when the output end of the second electric telescopic rod extends downward, the positioning rod at the bottom end of the output end is closely attached to the ground, realizing that the bottom of the stabilizing bottom plate is closely attached to the ground.

[0017] As a further improvement of the above solution, suction cups are fixed to both ends of the stabilizing bottom plate.

[0018] Through the above technical solution, when the stabilizing bottom plate is attached to a flat ground, the bottom of the stabilizing bottom plate is adsorbed to the ground through the suction cups, realizing the function of fixing the bottom of the stabilizing bottom plate to the ground.

[0019] As a further improvement of the above solution, a plurality of electric cylinders are fixed to the stabilizing bottom plate, and positioning forks are fixed to the output ends of the electric cylinders.

[0020] Through the above technical solution, a plurality of electric cylinders are equidistantly fixed to the stabilizing bottom plate, and the output end of each electric cylinder penetrates through the bottom of the stabilizing bottom plate and is fixed with a positioning fork. By moving the output end of the electric cylinder downward, the positioning fork is closely attached to a non-flat or soil ground, realizing the function of fully fixing the stabilizing bottom plate.

A moving wheel is installed at the output end of the first electric telescopic rod, and a positioning rod is fixed at the output end of the second electric telescopic rod. The box position is moved and adjusted by the moving wheel. After the adjustment is completed, the output end of the second electric telescopic rod extends downward so that the positioning rod is close to the ground, and at the same time, the output end of the first electric telescopic rod is retracted so that the moving wheel is off the ground, thereby improving the stability of the box.

[0023] 2. The load box for testing the movable generator set can adjust the horizontal steering of the connecting block and the stabilizing component by toggling the stabilizing component, and the bottom of the stabilizing base plate can be made close to the ground by adjusting the output end of the telescopic rod to move downward. At this time, the movable wheel can be rotated on the ground by pushing the box body, and the connecting block can slide in the stabilizing slide rail, so as to achieve accurate adjustment of the position of the box body. At this time, the box body can be rotated on the connecting block by rotating the box body to achieve angle switching, which further improves the accuracy and stability of the installation position movement, avoids deviations, and improves the convenience of angle adjustment.

When on a flat ground, the stable bottom plate is fixed by adsorption by the suction cup. When on an uneven ground, the positioning fork is inserted into the ground by moving the output end of the electric cylinder downward. This allows the device to be used in different environments, further improving its practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0035] Please refer to Figures 1-5As shown in the figure, the load box for testing a mobile generator set proposed in this embodiment includes a box body assembly 1, a supporting assembly 2, and a stabilizing assembly 3. The box body assembly 1 includes a plurality of the connecting corners 101. A vertical stabilizing rod 102 and a horizontal stabilizing rod 103 are movably connected to the connecting corners 101, and the vertical stabilizing rod 102 and the horizontal stabilizing rod 103 are perpendicular to each other. At the same time, a protective plate 108 and a side plate 109 are fixed between the vertical and horizontal stabilizing rods, and the protective plate 108 and the side plate 109 are perpendicular to each other. The box body assembly 1 uses eight connecting corners 101. The horizontal directions between the eight connecting corners are connected by the horizontal stabilizing rods 103, and the vertical directions are connected by the vertical stabilizing rods 102 to form the frame structure of the box body. The protective plate 108 and the side plate 109 are installed in the frame to form the overall load box, which can provide protection for the internal equipment of the box body. The supporting assembly 2 includes a supporting plate 201 fixed to the bottom of the box body assembly 1. A first electric telescopic rod 202 is fixed to the bottom of the supporting plate 201. The output end of the first electric telescopic rod 202 is movably hinged to a mounting plate 203. A moving wheel 204 is fixed to the mounting plate 203. At the same time, a regulating telescopic rod 207 is fixed to the bottom of the supporting plate 201. The output end of the regulating telescopic rod 207 is movably hinged to a connecting block 208. The supporting plate 201 is used to support the box body assembly 1. At the same time, the first electric telescopic rods 202 are installed at the four corner positions at the bottom of the supporting plate 201. The moving wheels 204 are installed through the mounting plates 203 at the bottoms of the first electric telescopic rods 202, so that the moving wheels 204 can rotate and move according to the pushing direction to realize the function of moving the position of the box body assembly 1. At the same time, by moving the output end of the regulating telescopic rod 207 downward, the function of fitting the bottom of the stabilizing assembly 3 to the ground is realized. By rotating the connecting block 208, the function of adjusting the angle of the stabilizing assembly 3 is realized. The stabilizing assembly 3 includes a stabilizing bottom plate 301 movably connected to the bottom of the supporting plate 201. A stabilizing slide rail 302 is fixed on the stabilizing bottom plate 301 along its length direction. The connecting block 208 is slidably connected in the stabilizing slide rail 302. When the bottom of the stabilizing bottom plate 301 is closely attached to the ground, the box body assembly 1 can move along the direction of the stabilizing slide rail 302 through the sliding of the connecting block 208 in the stabilizing slide rail 302, improving the stability of position adjustment.

[0036] The working principle of the load box for testing a mobile generator set proposed in this embodiment is as follows: when in use, by pushing the box assembly 1, the moving wheel 204 at the bottom rotates in the pushed direction, so as to move the position of the entire device. When it moves to the approximate position, the box assembly 1 is stopped from being pushed, and the connecting block 208 and the stable bottom plate 301 are rotated to the desired adjustment position by toggling the stable bottom plate 301. At this time, the output end of the control telescopic rod 207 is controlled to move downward, so that the stable bottom plate 301 is close to the ground at this angle. By controlling the suction cup 303 to be tightly adsorbed on the flat ground, or controlling the output end of the electric cylinder 304 to move downward, the bottom of the positioning fork 305 is closely attached to the ground, thereby ensuring the stability of the stable base plate 301. At this time, by pushing the box assembly 1, the connecting block 208 slides in the stable slide rail 302, so that the box assembly 1 can be translated along the angle of the stable assembly 3. After the position adjustment is completed, the output end of the second electric telescopic rod 205 is controlled to output downward, so that the positioning rod 206 is closely attached to the ground, and the position can be fixed.

By movably sleeving the installation ridges 104 in the strip-shaped grooves of the protection plate 108 and the side plates 109, the installation stability is improved, and the protection plate 108 and the side plates 109 are prevented from being separated from the effects of the vertical and horizontal stabilizing rods. The connecting corner 101 has corners in three directions and can be connected to the vertical and horizontal stabilizing rods 103. By rotating the rotating knob 105, the fixing screw 106 is threadedly connected to the corresponding end inside the connecting corner 101, realizing the convenience and stability of the connection between the vertical and horizontal rods. The rotating knob 105 is fixed in the middle of the fixing screw 106, so that one end of the fixing screw 106 is inside the vertical and horizontal stabilizing rods, while the other end is outside and can be inserted into the connecting corner 101. By rotating the positioning screw 107 clockwise, the front end of the positioning screw 107 is closely attached to the side of the fixing screw 106, realizing the fixation of the fixing screw 106 and improving the connection stability, and preventing the fixing screw 106 from freely rotating, which may cause the vertical and horizontal stabilizing rods to be separated from the effect of the connecting corner 101. When the output end of the second electric telescopic rod 205 extends downward, the positioning rod 206 at the bottom of the output end is closely attached to the ground, realizing that the bottom of the stabilizing base plate 301 is closely attached to the ground. When the stabilizing base plate 301 is attached to a flat ground, the bottom of the stabilizing base plate 301 is fixed to the ground by being adsorbed on the ground by the suction cup 303.
