Abstract
The utility model relates to a railway freight train technical field, in particular to stone tiny fragments of stone, coal, etc. Hopper car bottom door stop device, the lower part drive assembly who is connected including upper portion drive assembly, with upper portion drive assembly, lower part drive assembly and bottom door are constituteed to join in marriage and are connect, upper portion drive assembly below is equipped with one and prevents the bottom door to close back upper portion drive assembly can to continue the pivoted locating part. Therefore, the utility model has the advantages of as follows: 1. Reasonable in design, simple structure and practical completely, 2. Improved the bottom door and unloaded security and the reliability that the tiny fragments of stone, coal, etc. Was operated, can not make the bottom door accident open because the maloperation appearing.
Description
Technical field
The utility model relates to rail freight technical field, particularly a kind of stone tiny fragments of stone, coal, etc. hopper wagon bottom door inhibiting device.
Background technology
Railway freight traffic is the important support of socio-economic development, and building high-grade railway line is the prerequisite improving rail transportation efficiency.Therefore the technical performance of railway laying railway ballast stone tiny fragments of stone, coal, etc. hopper car is had higher requirement.Bottom door opening and closing mechanism is the gordian technique of stone tiny fragments of stone, coal, etc. hopper car, and therefore the design of bottom door opening and closing mechanism must meet the performance requriements of unloading for vehicle tiny fragments of stone, coal, etc. operation and guarantee safe operation.
The action principle of existing stone tiny fragments of stone, coal, etc. hopper wagon bottom door switching mechanism Main Basis four-bar mechanism controls the switch motion of bottom door.When opening and close bottom door, by rotating retarder handwheel, upper transmission axle is driven to rotate, the four-bar linkage be made up of upper crank throw, top rod, lower crank throw drives bottom drive axis, and bottom transmission shaft controls the on-off action of bottom door by the four-bar linkage that bottom door crank throw and bottom door connecting rod form.
After arriving off position, by observing the bottom door on off state direction board be fixed on upper transmission axle, can judge that bottom door is closed.At this moment according to " dead point " self-lock mechanism of four-bar mechanism, mechanism can pin bottom door and can not open.
But, after bottom door arrives off position, continue, with larger power rotation hand wheel, four-bar mechanism can be made to produce distortion, even cross " dead point " and bottom door is opened if there is maloperation, and very large to the destructive effect of mechanism.
Utility model content
The utility model mainly solves the technical matters existing for prior art; Provide a kind of improve bottom door unload the tiny fragments of stone, coal, etc. operation safety and reliability, a kind of stone tiny fragments of stone, coal, etc. hopper wagon bottom door inhibiting device that will bottom door be made surprisingly to open because there is maloperation.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of stone tiny fragments of stone, coal, etc. hopper wagon bottom door inhibiting device, is characterized in that, the bottom transmission component comprise upper transmission assembly, being connected with upper transmission assembly; Bottom transmission component and bottom door form and connect; A locating part stoping bottom door closedown upper back transmission component to be rotated further is provided with below described upper transmission assembly.
At above-mentioned a kind of stone tiny fragments of stone, coal, etc. hopper wagon bottom door inhibiting device, described upper transmission assembly comprises upper transmission axle, one end is enclosed within upper crank throw on upper transmission axle and one end and the hinged top rod of the upper crank throw other end.
At above-mentioned a kind of stone tiny fragments of stone, coal, etc. hopper wagon bottom door inhibiting device, described bottom transmission component comprises the hinged bottom door connecting rod of one end and the hinged bottom door crank throw of the hinged lower crank throw of the top rod other end, one end and the lower crank throw other end and one end and the bottom door crank throw other end; The described bottom door connecting rod other end and bottom door form hinged.
At above-mentioned a kind of stone tiny fragments of stone, coal, etc. hopper wagon bottom door inhibiting device, described locating part is arranged on below crank throw, this locating part is the limiting stopper of a L shape, and one end is fixed on frame, and the height of the other end is: upper crank throw just contacts with the top end face of the limiting stopper other end of L shape after rotating and bottom door being closed.
Therefore, the utility model tool has the following advantages: 1. reasonable in design, and structure is simply and completely practical; 2. improve safety and reliability that bottom door unloads tiny fragments of stone, coal, etc. operation, will bottom door be made because there is maloperation surprisingly to open.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.In figure, locating part 1, upper transmission axle 2, upper crank throw 3, top rod 4, bottom door composition 5, lower crank throw 6, bottom door crank throw 7, bottom door connecting rod 8.
Embodiment:
As shown in Figure 1, the utility model bottom transmission component of comprising upper transmission assembly, being connected with upper transmission assembly; Bottom transmission component and bottom door form and connect; A locating part stoping bottom door closedown upper back transmission component to be rotated further is provided with below described upper transmission assembly.
Wherein, upper transmission assembly comprises upper transmission axle, one end is enclosed within upper crank throw on upper transmission axle and one end and the hinged top rod of the upper crank throw other end; Bottom transmission component comprises the hinged bottom door connecting rod of one end and the hinged bottom door crank throw of the hinged lower crank throw of the top rod other end, one end and the lower crank throw other end and one end and the bottom door crank throw other end; The described bottom door connecting rod other end and bottom door form hinged; Locating part is arranged on below crank throw, and this locating part is the limiting stopper of a L shape, and one end is fixed on frame, and the height of the other end is: upper crank throw just contacts with the top end face of the limiting stopper other end of L shape after rotating and bottom door being closed.
Fig. 2,3 sets up bottom door inhibiting device action principle figure for stone tiny fragments of stone, coal, etc. hopper car.As can be seen from the figure; when bottom door is in the closed position; owing to adding bottom door inhibiting device; after bottom door arrives off position; this device can stop crank throw to be rotated further; four-bar mechanism can not be crossed at " dead point ", can prevent bottom door from surprisingly opening, can play a protective role to mechanism simultaneously.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as locating part 1, upper transmission axle 2, upper crank throw 3, top rod 4, bottom door composition 5, lower crank throw 6, bottom door crank throw 7, bottom door connecting rod 8 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
