Abstract
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
The present invention relates to elevating mechanism, be specifically related to a kind of lift cart.
Background technology
The high-power diesel engine newly made or the diesel engine after overhaul, un-wheeling repair all will carry out waterr rheostat test.Waterr rheostat test take water resistance as load, the various operating modes that simulation diesel engine runs, and detects the many kinds of parameters of diesel engine, testing result is processed, and on this basis, the duty of diesel engine is judged, check whether the diesel engine after assembling meets design requirement.Pass through waterr rheostat test; manufacture and the installation quality of each critical piece of diesel engine can be checked; adjust the power of diesel engine pulling electric generator group, transmission control, protection system and parameters; guarantee that each parts of diesel engine install correct, reliable in action, functional, security of operation, and control performance and the power characteristic of designing requirement can be played.
But at present in water resistance experimental provision, battery lead plate controls lifting by the screw lifting mechanism laid respectively on water resistance tank one opposite side lateral wall, wherein screw lifting mechanism comprises two guide rails vertically arranged, the bottom of two described guide rails is fixedly connected with the lateral wall of described water resistance tank respectively, lift cart and the screw rod passing vertically through lift cart is also provided with between two described guide rails, described lift cart and described screw flight coordinate, the bottom of described screw rod is provided with the drive motors for driving described screw rod to rotate, described drive motors is fixedly connected on two described guide rails by motor mount, the one side that two described guide rails are relative is respectively equipped with the chute extended along described rail length direction, the two ends of described lift cart are respectively equipped with the roller be rotatably assorted along described track length direction and described chute, battery lead plate installing rack for fixed plate electrode is fixedly connected with bracing frame towards the side of described lift cart respectively, support frame as described above is placed on the top of described lift cart.Lift cart bears the weight from battery lead plate, and in long lifting process, the screw thread that lift cart coordinates with screw flight will wear and tear.When thread abrasion to a certain extent after, just cannot bear the weight from lift cart electric pole plate again, will landing, and then battery lead plate is directly dropped in water resistance tank, make the miscellaneous equipment such as battery lead plate, water resistance tank cause damage.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is: how to provide one to avoid dropping from screw rod, improves the lift cart of safety in utilization.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of lift cart, comprise trolley body, the left and right sides of described trolley body is respectively equipped with the roller be rotatably assorted with trolley body, it is characterized in that: in described trolley body, be provided with cavity, the top of described trolley body is vertically provided with the screwed hole I be communicated with described cavity, the bottom of described trolley body is vertically provided with described screwed hole I opposite position the through hole be communicated with described cavity, the diameter of described through hole is greater than the aperture of described screwed hole I, the below being positioned at described screwed hole I in described cavity is also provided with back-up block, described back-up block runs through the screwed hole II be provided with the concentricity line of described screwed hole I, described screwed hole I is identical with the aperture of described screwed hole II, described back-up block is equipped with the lead vertically arranged, the length of described lead is greater than the maximum length of described back-up block in the vertical direction, the top of described lead is threaded with the inner top surface of described trolley body, the bottom of described lead is fixedly connected with for limiting the limited block of described back-up block from landing described lead.
In the present invention, screw rod extend in cavity from the through hole bottom trolley body, and stretches out from the top of trolley body through after the screwed hole II on back-up block and the screwed hole I on trolley body top successively.Because back-up block does not bear the weight from battery lead plate, therefore screwed hole II wearing and tearing are in use negligible.After the screwed hole I in trolley body damages, trolley body will fall, back-up block simultaneously in trolley body supports trolley body, bear the weight from battery lead plate, avoid trolley body to continue to drop, avoid the miscellaneous equipment such as battery lead plate, water resistance tank and cause damage, improve the security of use.
As optimization, the top of described trolley body is vertically provided with sleeve pipe, the bottom of described sleeve pipe is connected in described trolley body by flange is detachable, the top of described trolley body is provided with described sleeve pipe opposite position the perforation be communicated with described cavity, detachablely in described sleeve pipe be connected with lining, described screwed hole I is positioned on described lining, and the diameter of described perforation is greater than the aperture of described screwed hole I.When after screwed hole I wear damage, can change disassembling separately, to the whole replacing of trolley body, cost need not have been saved, also having made replacing be more prone to simultaneously.
In sum, beneficial effect of the present invention is: the present invention is supported the dolly dropped by the back-up block arranged again, and avoids after dropping and causes damage to the miscellaneous equipment such as battery lead plate, water resistance tank, improve the security of use.
