Description

Technical Field

[0001] The utility model relates to the technical field of industrial and mining electrical equipment, and particularly relates to a pantograph for a new type of industrial and mining electric locomotive. Background Art

[0002] As an important component of an industrial and mining electric locomotive, the pantograph for an industrial and mining electric locomotive is responsible for transmitting electric energy to the industrial and mining electric locomotive. However, under the existing technical conditions, due to its own structural limitations, the pantograph for an industrial and mining electric locomotive has the following problems: First, the existing pantographs for industrial and mining electric locomotives generally use manual traction to perform the operations of raising and lowering the pantograph, resulting in time-consuming and laborious operations. Second, the existing pantographs for industrial and mining electric locomotives generally adopt single-arm bow frames, resulting in relatively low overall structural strength. Based on this, it is necessary to invent a new type of pantograph for an industrial and mining electric locomotive to solve the problems of time-consuming and laborious operations and relatively low overall structural strength of the existing pantographs for industrial and mining electric locomotives. Summary of the Utility Model

[0003] The utility model provides a new type of pantograph for an industrial and mining electric locomotive to solve the problems of time-consuming and laborious operations and relatively low overall structural strength of the existing pantographs for industrial and mining electric locomotives.

[0004] The utility model is implemented by adopting the following technical solutions:

[0005] A new type of pantograph for an industrial and mining electric locomotive includes a buffer chassis, a bow head, a bow frame, and a drive control mechanism;

[0006] The bow head includes an iron core located above the buffer chassis; aluminum tubes, two lubricating sleeves, two pairs of washers, two pairs of rings, and two universal yokes are respectively rotatably assembled on the sides of the iron core; the inner ends of the two lubricating sleeves are respectively in contact with the two ends of the aluminum tube; the inner ends of the first pair of washers are respectively in contact with the outer ends of the two lubricating sleeves; the inner ends of the first pair of rings are respectively in contact with the outer ends of the first pair of washers; the inner ends of the second pair of rings are respectively in contact with the outer ends of the first pair of rings; the inner ends of the second pair of washers are respectively in contact with the outer ends of the second pair of rings; the inner ends of the two universal yokes are respectively in contact with the outer ends of the second pair of washers;

[0007] The bow frame includes two pairs of supports fixed to the front part of the upper surface of the buffer chassis; a rotating shaft is jointly rotatably supported on each pair of supports; two gears are respectively fixedly assembled on the left parts of the sides of the two rotating shafts, and the two gears are meshed with each other; two large arms are respectively vertically fixed to the middle parts of the sides of the two rotating shafts; two pivot shafts are respectively vertically fixed to the tails of the two large arms; a pair of sleeves are respectively rotatably assembled at both ends of each pivot shaft; two pairs of small arms are respectively vertically fixed to the outer sides of the two pairs of sleeves; the tails of the first pair of small arms are respectively fixed to the outer sides of the first pair of rings; the tails of the second pair of small arms are respectively fixed to the outer sides of the second pair of rings;

[0008] The driving control mechanism includes a first hinge seat, a second hinge seat, an electric control cylinder, a controller, a first hook seat, a second hook seat, and a tension spring. The first hinge seat is fixed to the left rear part of the upper surface of the buffer chassis. The second hinge seat is fixed to the left part of the side surface of the rearward-positioned rotating shaft. The cylinder body of the electric control cylinder is hinged to the first hinge seat. The end of the piston rod of the electric control cylinder is hinged to the second hinge seat. The controller is fixed to the left rear part of the upper surface of the buffer chassis, and the output end of the controller is connected to the control end of the electric control cylinder. The first hook seat is fixed to the right rear part of the upper surface of the buffer chassis. The second hook seat is fixed to the right part of the side surface of the rearward-positioned rotating shaft. The two ends of the tension spring are respectively hooked to the first hook seat and the second hook seat.

[0009] The specific usage process is as follows: First, when a bow-raising operation is required, the controller controls the piston rod of the electric control cylinder to shorten. The piston rod of the electric control cylinder drives the rearward-positioned rotating shaft to rotate forward through the second hinge seat. The rearward-positioned rotating shaft drives the forward-positioned rotating shaft to rotate reversely through the rearward-positioned gear and the forward-positioned gear in sequence (meanwhile, the rearward-positioned rotating shaft drives the tension spring to elongate through the second hook seat). Driven by the two rotating shafts, the two big arms, the two pivot shafts, and the two pairs of small arms all rotate and close, thereby pushing the bow head upward, so that the bow head contacts the catenary. Second, when a bow-lowering operation is required, the controller controls the piston rod of the electric control cylinder to elongate. The piston rod of the electric control cylinder pushes the rearward-positioned rotating shaft to rotate reversely through the second hinge seat. The rearward-positioned rotating shaft drives the forward-positioned rotating shaft to rotate forward through the rearward-positioned gear and the forward-positioned gear in sequence (meanwhile, the tension spring pulls the rearward-positioned rotating shaft to rotate reversely through the second hook seat, and the tension spring thus shortens). Driven by the two rotating shafts, the two big arms, the two pivot shafts, and the two pairs of small arms all rotate and open, thereby driving the bow head to lower, so that the bow head disengages from the catenary.

[0010] Based on the above process, compared with the existing pantographs for industrial and mining electric locomotives, the novel pantograph for industrial and mining electric locomotives described in the present invention has the following advantages by adopting a brand-new structure: First, the present invention no longer performs bow-raising and bow-lowering operations by manual traction, but by an automatic control method, thus making the operation time-saving and labor-saving. Second, the present invention no longer adopts a single-arm bow frame, but a double-arm bow frame, thus effectively improving the overall structural strength.

[0011] Further, the bow frame further includes two short reinforcing beams and two long reinforcing beams. The first short reinforcing beam is fixed between the front side surfaces of the first pair of small arms; the second short reinforcing beam is fixed between the front side surfaces of the second pair of small arms; the first long reinforcing beam is fixed between the rear side surfaces of the first pair of small arms; the second long reinforcing beam is fixed between the rear side surfaces of the second pair of small arms. During use, the two short reinforcing beams and the two long reinforcing beams both play a role in strengthening the bow frame, thereby further improving the overall structural strength.

[0012] Further, a locking device is also included. The locking device includes a travel switch, a U-shaped locking hook, a locking ear plate, and an electric push rod. The travel switch is fixed to the front part of the upper surface of the buffer chassis, and the output end of the travel switch is electrically connected to the input end of the controller; the U-shaped locking hook is fixed to the side surface of the front large arm, and the U-shaped locking hook is separably in contact with the contact of the travel switch; the locking ear plate and the electric push rod are both fixed to the front part of the upper surface of the buffer chassis, and the locking ear plate and the electric push rod are respectively located on the left and right sides of the travel switch; the rod end of the electric push rod is separably inserted into the ear holes of the U-shaped locking hook and the locking ear plate, and the control end of the electric push rod is electrically connected to the output end of the controller. During use, the U-shaped locking hook rotates with the front large arm. After the bow lowering operation is completed, the U-shaped locking hook contacts the contact of the travel switch, and the travel switch sends a locking signal to the controller. The controller controls the rod of the electric push rod to extend according to the locking signal, and the rod of the electric push rod is thus inserted into the ear holes of the U-shaped locking hook and the locking ear plate, thereby locking the positions of the bow frame and the bow head.

[0013] Further, a protective cover is also included. The protective cover covers two of the two pairs of supports, two gears, and the electro-hydraulic cylinder, which are located on the left.

[0014] The utility model effectively solves the problems of time-consuming and laborious operation and relatively low overall structural strength of the pantograph for industrial and mining electric locomotives, and is applicable to industrial and mining electric locomotives.
