Description
Technical field
The utility model relates to a kind of stopping means, and specifically a kind of excavator side door opening angle automatic limit device, belongs to excavator field.
Background technology
Excavator generally has 2-3 to fan side door, in order to check, overhauling or safeguard the parts such as various Hydraulic Elements, electrical part and motor piece inside excavator, needs often to open corresponding side door.Side door must be fixed on appropriate location after opening, and handled easily personnel launch maintenance work.In prior art all there is spacing inconvenience or spacing problem not in place in excavator stopping means, positioning, operating cumbersome as arranged hook above side door; Some operator often conveniently simply directly opens and does not use limit function behind the door and directly check each parts of the inside, overhaul or safeguard, when side door by external force affect close suddenly time, can affect the operating efficiency of operator, What is more causes the accident crushing people to occur.
The Chinese utility model patent manual announced on March 27th, 2013 discloses one " excavator side door opening angle the automatic limit device " (application number 201220443250.9 of the applicant's application, notification number CN 202831914 U), this stopping means comprises framework, cottor pin and connecting rod, framework is connected through the hinge on side door, the bottom of framework is provided with slideway, slideway is provided with limit point, the bottom of side door offers hinge hole, the slideway in base of frame is inserted in one end of connecting rod, and connecting rod is connected with framework with cottor pin by packing ring, the other end of connecting rod inserts the hinge hole on bottom side door, and connecting rod is connected with side door with cottor pin by packing ring, slideway in base of frame is inverted "L" shaped slideway, and its inverted "L" shaped kink is the limit point of slideway.When needing the various parts checked, overhaul or safeguard inside excavator, open side door, the other end of side door drivening rod slides in the bottom slide track of framework, when rod slide is to the limit point of slideway, connecting rod can not slide again, side door opening angle is fixed, thus achieves the automatic spacing to side door opening angle.Use this stopping means of discovery in the situations such as strong wind or personnel touch by mistake, the active force in horizontal direction can make side door rock, and connecting rod departs from anchor point sometimes, thus loses position-limiting action.
Summary of the invention
For solving the problem, the utility model provides a kind of excavator side door opening angle automatic limit device, can suppress rocking of excavator side door in the horizontal direction, avoids stopping means to depart from limit point.
For achieving the above object, a kind of excavator side door opening angle of the utility model automatic limit device, comprise slideway, connecting rod and countersunk head alignment pin, installation of slide track is in side door base of frame, connecting rod one end is connected with bottom side door in hinged way, and the other end is fixedly connected with countersunk head alignment pin; Slideway is provided with counterbore, and counterbore shape is corresponding with countersunk head alignment pin shape; Countersunk head alignment pin inserts in slideway, can be free to slide along slideway.
During enabling, countersunk head alignment pin slides along slideway, and when sliding into counterbore position, countersunk head alignment pin sinks under the effect of self gravitation, falls into counterbore, latched position, thus plays the tailor-made use of the automatic limiting of side door opening angle.
At closing time, countersunk head alignment pin is upwards mentioned by operating personnel, makes it depart from counterbore, slideway slides, shut side door.
Beneficial effect: the effect that present invention utilizes gravity, realize automatic spacing function, the cooperation of counterbore and countersunk head alignment pin, structure comparison is tight, intermediate gap is little, the wind-force that horizontal direction is come or personnel's maloperation all can not make side door produce large rocking, and countersunk head alignment pin can not depart from counterbore, and position-limiting action is good.
Further, for the one end avoiding the vibrations of vehicle vertical direction to cause connecting rod to be connected with slideway departs from counterbore, arrange cover plate in counterbore side, cover plate and framework are connected in hinged way, and hinge point is provided with elastomeric element; Cover plate covers counterbore under the effect of elastomeric element, under external force can horizontal axis.During enabling, cover plate pushed open by countersunk head alignment pin, falls into counterbore, and cover plate is auto-returned under the elastic force effect of elastomeric element, covers counterbore; Even if there are the vibrations of vertical direction like this, under the effect not having manpower, countersunk head alignment pin also can not depart from counterbore, guarantees the limit function of this device.At closing time, operating personnel push cover plate open, mention countersunk head alignment pin, make it depart from counterbore, slideway slides, shut side door.
Accompanying drawing explanation
Fig. 1 is that the present invention assembles schematic diagram;
implementation
Below in conjunction with accompanying drawing, the present invention is further described:
A kind of excavator side door opening angle automatic limit device, comprise slideway 1, connecting rod 2 and countersunk head alignment pin 3, slideway 1 is arranged on bottom side door framework 7, and connecting rod 2 one end is connected in hinged way with bottom side door 6, and the other end is fixedly connected with countersunk head alignment pin 3; Slideway 1 is provided with counterbore 4, counterbore 4 shape is corresponding with countersunk head alignment pin 3 shape; Countersunk head alignment pin 3 inserts in slideway 1, can be free to slide along slideway 1.
During enabling, countersunk head alignment pin 3 slides along slideway 1, when sliding into counterbore 4 position, countersunk head alignment pin 3 sinks under gravity, falls into counterbore 4, latched position, thus play the tailor-made use of the automatic limiting of side door opening angle, no matter be side direction or forward wind-force, comprise personnel and touch by mistake countersunk head alignment pin 3 all can not be made to rise from counterbore 4, guarantee the position-limiting action of this device.
At closing time, countersunk head alignment pin 3 is upwards mentioned by operating personnel, makes it depart from counterbore 4, slideway 1 slides, shuts side door.
Further, for avoiding the vibrations of vehicle vertical direction to cause countersunk head alignment pin 3 to depart from counterbore, arrange cover plate 5 in counterbore side, cover plate 5 and framework are connected in hinged way, and hinge point is provided with elastomeric element; Cover plate 5 covers counterbore 4 under the elastic force effect of elastomeric element, under external force can horizontal axis.During enabling, cover plate 5 pushed open by countersunk head alignment pin 3, falls into counterbore 4, and cover plate 5 is auto-returned under the effect of elastic force, covers counterbore 4; Even if there are the vibrations of vertical direction like this, under the effect not having manpower, countersunk head alignment pin 3 also can not depart from counterbore 4, guarantees the limit function of this device.At closing time, operating personnel push cover plate 5 open, mention countersunk head alignment pin 3, make it depart from counterbore 4, slideway 1 slides, shuts side door.
Further, for convenience of personnel's maintenance, can multiple counterbore 4 be set on slideway 1, to meet the difference of side door opening angle.
