Abstract

The utility model relates to a telescopic-cylinder-type filling-pipe drop-pipe swing device, which belongs to the fields of machinery and fluid transportation. In order to solve the problems that a drop pipe of a filling pipe can not exceed a guard rail of a tank car with a high guard rail, the falling of the drop pipe can impact the tank car, and a sealing cap of the drop pipe can not cover over the tank mouth of the tank car after the drop pipe falls off, an outer arm of the filling pipe can be provided with a telescopic cylinder bracket, a telescopic cylinder can be fixed on the telescopic cylinder bracket, the drop pipe of the filling pipe is provided with a push-and-pull arm, the push-and-pull arm is provided with a connecting shaft of the telescopic cylinder, a telescopic rod in the telescopic cylinder is connected with the connecting shaft of the telescopic cylinder on the push-and-pull arm, and the telescopic-cylinder-type filling-pipe drop-pipe swing device is formed thereby. Through the movement of the telescopic rod in the telescopic cylinder, when the drop pipe swings upwards to exceed the guard rail of the tank car with a high guard rail, the drop pipe can be moved to the position above the tank mouth of the tank car; the angle between the drop pipe and the outer arm of the filling pipe can be adjusted properly by the telescopic cylinder, so that the drop pipe can not impact the tank mouth of the tank car when the drop pipe enter the tank mouth and the sealing cap of the drop pipe can cover over the tank mouth of the tank car after the drop pipe falls off. The telescopic-cylinder-type filling-pipe drop-pipe swing device is mainly applied to filling pipes.

Description

Telescopic cylinder type oil filling riser vertical tube swinging device

Technical field

The utility model relates to a kind of telescopic cylinder type oil filling riser vertical tube swinging device, belongs to machinery and FLUID TRANSPORTATION field.

Technical background

At present, the widespread use oil filling riser loads and unloads liquid chemical in tank car both at home and abroad, but runs into two troubles through regular meeting when charge and discharge operations.The one because oil filling riser vertical tube is longer, as tank car guardrail when higher, oil filling riser vertical tube just can not be crossed the tank car guardrail and enter tank car jar mouth, needs people's strength that costs a lot of money could lift the tank car guardrail to oil filling riser vertical tube and put into tank car jar mouth.The 2nd, when oil filling riser vertical tube is suspended in tank car jar mouth top when falling, because the up-and-down movement track of oil filling riser outer arm is a circular arc, the nanubrium that falls often all can be run into tank car jar mouth, oil filling riser vertical tube can often be broken, if have seal cap on the oil filling riser vertical tube, seal cap also can deflect away from and covers incessantly tank car jar mouth with nanubrium during the whereabouts.

Summary of the invention

The purpose of this utility model is that a kind of telescopic cylinder type oil filling riser vertical tube swinging device will be provided, it is installed between oil filling riser outer arm and the nanubrium, nanubrium has upwards been put crossed the tank car guardrail easily, but also can cooperate the path of motion of oil filling riser outer arm, do not bump tank car jar mouth when oil filling riser vertical tube is fallen, and the seal cap on the nanubrium can cover tank car jar mouth and not deflect away from.

The technical scheme that the utility model adopted is: the telescoping cylinder support is set on the oil filling riser outer arm, on oil filling riser vertical tube top or sidewall push-pull arm is set, the telescoping cylinder adapter shaft is arranged on the push-pull arm.The telescoping cylinder cylinder body is fixed on the telescoping cylinder support, the expansion link of telescoping cylinder is connected with telescoping cylinder adapter shaft on the push-pull arm, by stretching of expansion link in the telescoping cylinder, oil filling riser vertical tube is swung up and down, when nanubrium swings upwards into above the tank car guardrail height, just can cross the tank car guardrail and arrive a jar mouth, adjust angle between nanubrium and the outer arm by telescoping cylinder, when oil filling riser vertical tube is fallen, drop to jar a mouthful center in the situation of neither bumping tank car jar mouth, can make seal cap on the nanubrium cover tank car jar mouth again and do not deflect away from.

Description of drawings

Fig. 1 is a structural representation of the present utility model, a kind of telescopic cylinder type oil filling riser vertical tube swinging device.The 1st, oil filling riser outer arm, the 2nd, oil filling riser vertical tube, the 3rd, push-pull arm, the 4th, telescoping cylinder adapter shaft, the 5th, telescoping cylinder support, the 6th, telescoping cylinder, the 7th, seal cap.

The specific embodiment

As shown in Figure 1, telescoping cylinder support 5 is fixed on the oil filling riser outer arm 1, push-pull arm 3 is fixed on the oil filling riser vertical tube 2, push-pull arm 3 can be fixed on the top of nanubrium 2, also can be fixed on the sidewall of nanubrium 2, has seal cap 7 on the nanubrium 2.Telescoping cylinder adapter shaft 4 is arranged on the push-pull arm 3.The cylinder body of telescoping cylinder 6 is fixed on the telescoping cylinder support 5, the expansion link top of telescoping cylinder 5 is fixed on the telescoping cylinder adapter shaft 4 on the push-pull arm 3, by stretching of telescoping cylinder 6, oil filling riser vertical tube 2 will swing up and down, on nanubrium 2, put certain altitude, when surpassing the guardrail of high guardrail tank car, nanubrium 2 can be moved to tank car jar mouth top, the flexible angle of adjusting between oil filling riser vertical tube 2 and the oil filling riser outer arm 1 by telescoping cylinder 6 again, drop to a jar mouthful center in the situation of neither bumping tank car jar mouth when nanubrium 2 is fallen, can make seal cap 7 on the nanubrium 2 cover tank car jar mouth again and do not deflect away from.

Claims

A kind of telescopic cylinder type oil filling riser vertical tube swinging device, be linked in sequence by the push-pull arm of telescoping cylinder support, telescoping cylinder, band telescoping cylinder adapter shaft and form, it is characterized in that the telescoping cylinder support is fixed on the oil filling riser outer arm, the push-pull arm of band telescoping cylinder adapter shaft is fixed on the oil filling riser vertical tube, is connected with telescoping cylinder between the push-pull arm of telescoping cylinder support and band telescoping cylinder adapter shaft.

Telescopic cylinder type oil filling riser vertical tube swinging device described in the claim 1, the push-pull arm of its band telescoping cylinder adapter shaft can be arranged on the oil filling riser vertical tube top, also can be arranged on the sidewall of nanubrium.
