Problems solved by technology
When the thread is worn to a certain extent, it can no longer bear the weight of the electrode plate on the lifting trolley, and it will slip, and then the electrode plate will fall directly into the water resistance box, causing damage to the electrode plate, water resistance box and other equipment

Embodiment Construction
[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0014] like figure 1 and figure 2 As shown, a lifting trolley in this specific embodiment includes a trolley body 1, the left and right sides of the trolley body 1 are respectively provided with rollers 2 that are rotatably matched with the trolley body 1, and the trolley body 1 is provided with a cavity body, the top of the trolley body 1 is provided with a threaded hole I3 communicating with the cavity along the vertical direction, and the bottom of the trolley body 1 is provided with a threaded hole I3 corresponding to the threaded hole I3 along the vertical direction. A through hole communicating with the cavity, the diameter of the through hole is larger than the diameter of the threaded hole I3, and a support block 4 is located below the threaded hole I3 in the cavity, and the support block 4 is set through There is a threaded hole II on the same cen...

The invention discloses a lifting trolley which comprises a trolley body. Rolling wheels rotationally matched with the trolley body are arranged on the left side and the right side of the trolley body respectively. A cavity is formed in the trolley body. A threaded hole I communicated with the cavity is formed in the top of the trolley body in the vertical direction, and a through hole communicated with the cavity is formed in the position, corresponding to the threaded hole I, of the bottom of the trolley body in the vertical direction. A supporting block is further arranged in the position, below the threaded hole I, in the cavity. A threaded hole II sharing the same center line with the threaded hole I is formed in the supporting block in a penetrating manner. A guide pillar arranged in the vertical direction is arranged on the supporting block in a penetrating manner, and the top end of the guide pillar is in threaded connection with the inner top face of the trolley body. The bottom end of the guide pillar is fixedly connected with a limiting block used for limiting the supporting block from falling from the guide pillar. According to the lifting trolley, the falling trolley is supported again through the supporting block, damage to an electrode plate, a water resistance tank and other equipment is avoided after the trolley falls, and the use safety is improved.
Description
technical field [0001] The invention relates to a lifting mechanism, in particular to a lifting trolley. Background technique [0002] Newly built high-power diesel engines or diesel engines that have been overhauled or repaired must undergo water resistance tests. The water resistance test uses water resistance as the load to simulate various operating conditions of the diesel engine, detect various parameters of the diesel engine, process the detection results, and use this as a basis to judge the working state of the diesel engine and check the assembly Whether the final diesel engine meets the design requirements. Through the water resistance test, you can check the manufacturing and installation quality of the main components of the diesel engine, adjust the power, transmission control, protection system, and various parameters of the diesel engine traction generator set, and ensure that the components of the diesel engine are installed correctly, reliable in action, g...
