Summary of the invention
The object of the present invention is to provide a kind of four post lifting machines improving safety performance, there is the problem of potential safety hazard during to solve in prior art and to use lifting machine to repair the automobile of brake system fault, improve the safety performance used in lifting machine process.
The present invention is achieved through the following technical solutions:
A kind of four post lifting machines improving safety performance, comprise four pillar stiffeners, be connected to lifting frame on four pillar stiffeners, and be fixed on the table top with ramp of two axis being parallel between described lifting frame, described table top is provided with groove near the one end in described ramp, described groove floor is fixed with mouth actuating device upward, and the mouth of described actuating device is connected with the first block; Described table top is also fixed with the second block away from the surface of one end, ramp.There is the problem of potential safety hazard when repairing the automobile of brake system fault for existing lifting machine, the invention provides a kind of four post lifting machines improving safety performance, actuating device is utilized to drive the first block to be protruding on table top when needed, coordinate the second block being fixed on the table top other end, stop that the inertia of automobile moves, guarantee the safety in use procedure.Actuating device described in the present invention includes the common type of drive of the mechanical fields such as driven by power, hydraulic-driven or pneumatic actuation.Described first block is not when needing to use, and when namely not using actuating device to drive it to move, the upper surface of its upper surface and described table top is in same level, does not affect normally sailing into or exiting of automobile.The clutch end of described actuating device is connected with the first block, by accessory drive, can drive the first block, make it be protruding on table top, utilizes the first block to stop possible the moving backward of automobile, eliminates the potential safety hazard that may exist.In use procedure of the present invention, drive a car and reach described table top by ramp and be parked in table top medium position, if now the brake system of automobile exists fault, move under effect of inertia, then second block that can be fixed stopped.Start described actuating device afterwards, drive the first block to be protruding on table top, also stop is formed to the direction of retreat of automobile, form the stop on two sides, front and back with this, reduce potential safety hazard, improve the safety repaired in process.
Preferably, described actuating device is linear electric motors.Compared to hydraulic pressure or pneumatic actuation mode, motor driver structure is simple, convenient operation and use, and does not need to configure extra propulsion source, utilizes the power-supply system of lifting machine to realize.
Preferably, described actuating device is bolted the bottom surface being connected to described groove.Bolt firm and reliable connection and be easy to dismounting, can be convenient to remove and install, be convenient to the maintenance to actuating device or replacing while guarantee this device stability in use.
Further, the upper surface of described table top is provided with the lines increasing friction coefficient.Utilize concavo-convex lines to increase friction coefficient between described table top and motor tire, guarantee further to use the safety in lifting machine maintenance automobile process.
Preferably, described second block and described table top one-body molded.One-body molded by manufacturing process, can improve the strength of connection between the second block and table top.
The present invention compared with prior art, has following advantage and beneficial effect:
A kind of four post lifting machines improving safety performance of the present invention, actuating device is utilized to drive the first block to be protruding on table top, stop automobile movement backward, utilize simultaneously table top away from ramp end the second block of fixing, stop that automobile inertia forward moves, form the stop on two sides, front and back with this, reduce potential safety hazard, improve the safety repaired in process.
