Detailed Description
One of the embodiments of the present invention, a model having two side-by-side spray heads, is described below with reference to the accompanying drawings, and it should be understood that the embodiments described herein are only for illustrating and explaining the present invention, and are not intended to limit the present invention.
As shown in fig. 1 to 2, a bogie elevator includes: the device comprises a fixed frame 1, a lifting frame 2, a lifting driving device 3 and a bogie supporting block 4; the lifting frame is arranged on the lifting driving device and is arranged in the fixed frame through the linear guide rail and the sliding block, and the bogie support block is arranged on the lifting frame;
the fixed frame 1 is a rectangular three-dimensional steel structure frame; the fixing frame is installed on an embedded steel plate of a foundation and is formed by welding steel plates, and sufficient rigidity and strength, good shock absorption and lasting stability are guaranteed through finite element analysis and calculation.
The lower part of the lifting frame 2 is a rectangular steel member 2.1, and four upward upright posts 2.2 are arranged at four corners of the lifting frame; four lifting columns are connected into a rigid body, and the lifting synchronous errors of the four lifting columns are zero on the mechanical structure. The direction of the lifting upright post is guided by 4 heavy-load linear guide rails, so that the lifting stability and reliability are ensured.
A linear guide rail 2.3 and a sliding block 1.1 are matched between the fixed frame and the upright post of the lifting frame;
the lifting driving device 3 is characterized in that two ends of a motor 3.1 are respectively connected with an output shaft 3.2, a lifter 3.3 and a screw rod 3.4;
the lower part of the lifting frame is matched with a screw rod of a lifting driving device and is provided with a working nut 2.4, an anti-falling screw 2.5 nut and a bearing 2.6, and a stop rod can be arranged between the working nut and the anti-falling nut; a proximity switch is arranged between the working nut and the anti-falling nut, the distance between the working nut and the anti-falling nut is adjustable, and when the working nut is worn and fails, an alarm is given and the operation is stopped; the nut on the screw rod can be self-locked, and the lifting upright post stops at any time and is fixed at the position by the self-locking function of the screw rod nut. In order to ensure stable lifting of the four stand columns, the four stand columns are designed into a whole rigid body, four heavy-load linear guide rails are arranged for guiding, and the rigid body is lifted by driving two lifters by one double-extension-shaft motor, namely a double-screw rod structure. The double-screw structure not only implements multiple guarantees on the stability of the double-screw structure, but also further ensures the safety, and under the special conditions of breakage of one screw rod and the like, the other screw rod can support the whole rigid body, thereby ensuring that no safety accident can occur.
Four sets of the bogie supporting blocks 4 are respectively arranged on four upright posts of the lifting frame, and the supporting blocks are all movable V-shaped supporting blocks 4.1; the front and back directions of two wheels of the bogie can be effectively fixed;
the movable support block is characterized in that a linear guide rail 2.3 and a sliding block 1.1 are arranged below the support block, and a positioning hand pin 4.2 is arranged in the support block; the tightness of the positioning hand pin is manually operated;
the invention is provided with a special electric control system.
The invention is arranged below the ground level in the pit, and does not influence any work of a workshop.
The bogie is a steering mechanism of a train and is a rectangular framework consisting of double shafts and four wheels, before a lift is hoisted, the track gauge size is determined, a support block on a stand column of the lift is correspondingly adjusted and positioned, then the bogie is hoisted on the support blocks of the four stand columns, a motor of the lift is started, a lifting frame is lifted to the height convenient for a worker to operate, and various assembling and disassembling works can be conveniently carried out.
Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
