Abstract
The utility model relates to a protection device for the top of a tank body on a tank truck, in particular to a pneumatic protection device, which comprises a guardrail and an air cylinder which are movably linked with each other, the guardrail is hinged with the tank body, the air cylinder is hinged with the tank body, and the air cylinder is communicated with the air source of the tank truck. The guardrail is driven by the air cylinder, and the guardrail is driven to move up or down as the air cylinder pushes vertical bars to move up or down. The upward and downward movement of the guardrail can be automatically controlled by the air cylinder, and the guardrail can be prevented from accidentally falling after being lifted, thereby ensuring the safety of operators at the top of the tank body. Since the protection device is controlled by the air cylinder, unexpected upward movement of the protection device can be avoided.
Description
Technical field
The utility model relates to a kind of protective device that is used for motor tank tuck tank body top, relates in particular to a kind of pneumatic protective device.
Background technology
The people needs a safety guide rail and guarantees personal safety when the abhiseca operation of motor tank tuck, meets accident when preventing operating personnel's operation and falls.Existing tank deck protective device is made up of cross bar, montant, steel rope, supporting seat and strut etc., existing protective device must could come on abhiseca by operating personal in pull-up, increased safety hazard, and this protective device must spur operation inconvenience by manpower.After existing guard rail falls, in the process that tank car travels, under the effect of external force, might rise automatically, increase the height of vehicle, can reduce traveling security.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of safe and reliable, easy to operate pneumatic protective device.
Pneumatic protective device of the present utility model comprises guard rail and cylinder, and described guard rail and cylinder flexibly connect, and described guard rail and tank body are hinged, and described cylinder and tank body are hinged.
Preferably, described guard rail comprises cross bar and montant, and an end of described cross bar and each montant is linked, and the other end and the tank body of described montant are hinged.
Wherein, described cylinder front end comprises an expansion link, and the montant of described expansion link and described guard rail flexibly connects, and the afterbody of described cylinder is provided with hinge seat, and described cylinder is hinged by described hinge seat and described tank body.
Wherein said cylinder is connected with the source of the gas of tank car.When source of the gas entered cylinder, the expansion link that the piston in the cylinder drives the cylinder front end stretched out, and expansion link drives the montant near vertical in tank body, and this moment, guard rail rose.After operating personal is withdrawn from abhiseca, cut off the air inlet source of cylinder, cylinder piston shrinks automatically, and expansion link drives guard rail and draws in.
Pneumatic protective device of the present utility model can be used for the safety precaution of flow container abhiseca, when reality is used pneumatic protective device of the present utility model can be set in the both sides of flow container abhiseca respectively.
Pneumatic protective device of the present utility model, described guard rail is driven by cylinder, and the source of the gas of the vehicle of described cylinder and described motor tank tuck itself is linked, and promotes montant by cylinder and rises or fall, and rises and falls thereby drive guard rail.Pneumatic protective device of the present utility model, by rising and falling of cylinder automatic guidance guard rail, guard rail can accident not fall after rising, and has guaranteed the safety of abhiseca operating personal.After existing guard rail falls, might rise automatically under the effect of external force in the process of vehicle ', increase the height of vehicle, can reduce traveling security, protective device of the present utility model can unexpectedly not risen by cylinder control.
Introduce pneumatic protective device of the present utility model in detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the front elevation of pneumatic protective device of the present utility model;
Fig. 2 is the lateral plan of pneumatic protective device of the present utility model when using;
Fig. 3 is the enlarged drawing in zone shown in the A among Fig. 1;
Fig. 4 is the enlarged drawing in zone shown in the II among Fig. 2.
The specific embodiment
As depicted in figs. 1 and 2, pneumatic protective device of the present utility model comprises guard rail 10 and cylinder 30, and described guard rail 10 flexibly connects with cylinder 30, and described guard rail 10 is hinged with tank body, and described cylinder 30 is hinged with tank body.
Described guard rail 10 comprises cross bar 11 and montant 12 (a plurality of montant), described cross bar 11 is linked with an end of each montant 12, the other end and the tank body of described montant 12 are hinged, and guard rail 10 also comprises many steel ropes 13, and cross bar 11, montant 12 and steel rope surround guard rail jointly.
As Fig. 1, Fig. 3 and shown in Figure 4, described cylinder 30 front ends comprise an expansion link 35, piston in described expansion link 35 and the cylinder is connected, described expansion link 35 flexibly connects by pivot pin 34 with the montant 12 of described guard rail 10, the afterbody of described cylinder 30 is provided with hinge seat 32, tank body is provided with the hinge link 33 that cooperates with described hinge seat 32, and described cylinder is hinged with described tank body by described hinge seat 33.Described guard rail 10 can be done radial motion with the position of the adapter shaft of tank body around the montant 12 of guard rail, and described guard rail 10 can rise on tank body and fall.
As Fig. 1, Fig. 3 and shown in Figure 4, described cylinder 30 is connected with the source of the gas of tank car.When source of the gas entered cavity 31 in the cylinder, the expansion link 35 that the pistons in the cylinder 30 drive the cylinder front end stretched out, and expansion link 35 drives montants 12 near vertical in tank body, and this moment, guard rail 10 rose.After operating personal is withdrawn from abhiseca, cut off the air inlet source of cylinder 30, cylinder piston shrinks automatically, and expansion link 35 drives guard rail and draws in.
As shown in Figure 2, pneumatic protective device of the present utility model can be used for the safety precaution of flow container abhiseca, when reality is used pneumatic protective device of the present utility model can be set in the both sides of flow container abhiseca respectively.
Pneumatic protective device of the present utility model, described guard rail 10 is driven by cylinder 30, and described cylinder 30 is linked with the source of the gas of the vehicle of described motor tank tuck itself, promotes montant 12 by cylinder 30 and rises or fall, thereby prop whole protection hurdle 10.Pneumatic protective device of the present utility model, but the rising and falling of automatic guidance guard rail 10, and guard rail 10 can accident not fall after rising, and guaranteed the safety of abhiseca operating personal.After existing guard rail falls, might rise automatically under the effect of external force in the process of vehicle ', increase the height of vehicle, can reduce traveling security, protective device of the present utility model can unexpectedly not risen by cylinder control.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
