Description

The tank car filling liquid closes the pipe machine

The utility model provides a kind of tank car filling liquid to close the pipe machine, belongs to filling liquid machinery field.

When the inflammable and explosive liquid of can, produce for fear of static and spark, can not electrical installation, generally be to be power with pressurized air.Existing technology is with two joint or three displacements of cylinders, is commonly referred to as the more piece cylinder, is power with pressurized air, makes cylinder flexible, and then the pipe outlet of carrying liquid is inserted from the tank car mouth or pulls out.This more piece cylinder involves great expense, and the seal ring between the more piece weares and teares easily and lost efficacy, therefore maintenance load is big, maintenance cycle is short, and bulky, the Heavy Weight of this more piece cylinder, for bigger difficulty all being arranged, in addition, skid easily between trundle and track on the existing installation by dress, dismounting and maintenance.

The purpose of this utility model provide a kind of simple in structure, cost is low, installation and maintenance are convenient, the tank car filling liquid of locking and accurate positioning, reliable working performance closes the pipe machine.

The utility model is achieved in that

A kind of tank car filling liquid closes the pipe machine, comprise track, dolly and be fixed on liquid-filling machine on the dolly, liquid-filling machine comprises gas motor, bent plate, drive coupling, worm reduction gear, gear, orienting sleeve, tooth bar square shaft and terminal pad, wherein bent plate, worm reduction gear, orienting sleeve all are fixed on the vehicle frame, the gas motor is fixed on the bent plate, and be fixedly connected through drive coupling and worm reduction gear, be provided with in the orienting sleeve that wheel tooth on tooth bar square shaft and the worm reduction gear output shaft is nibbled and, the bottom of tooth bar square shaft is provided with terminal pad.

Described tank car filling liquid closes the pipe machine, is provided with manual input square shaft at the worm screw other end of worm reduction gear, and the wheel of dolly changes gear, and track is a tooth bar, wheel and track be tooth nibble and.

The utility model compared with prior art, and is simple in structure, in light weight, and installing/dismounting is easy to maintenance, and cost is low; Worm reduction gear has self-lock ability, can rest on tooth bar on any position at any time, has saved the blocking device on the more piece cylinder, has increased the reliability of work; Set up hand lift system, can manual work when source of the gas or gas motor go wrong; And trundle changed into gear, and track is changed into tooth bar, separated time the problem of skidding, make the accurate positioning of dolly reliable.

Fig. 1 is a structural representation of the present utility model;

The utility model is described in further detail below in conjunction with accompanying drawing:

Bent plate 2, worm reduction gear 4, orienting sleeve 6 all are fixed on the vehicle frame 10, gas motor 1 is fixed on the bent plate 2, and be fixedly connected through drive coupling 3 and worm reduction gear 4, be provided with in the orienting sleeve 6 that tooth bar square shaft 7 is nibbled with gear 5 teeth on the worm reduction gear 4 and, the bottom of tooth bar square shaft 7 is provided with terminal pad 9, is provided with manual input square shaft 8 at the worm screw other end of worm reduction gear 4, and wheel 11 is a gear, track 12 is a tooth bar, and wheel 11 is the tooth engagement with track 12.

During work, by Air Valve Control, with pressurized air is power, drive the 1 positive and negative rotation of gas motor, make gear 5 positive and negative rotations by drive coupling 3, worm reduction gear 4, order about tooth bar square shaft 7 and in orienting sleeve 6, move up and down, drive terminal pad 9 pipe outlet of carrying liquid is pulled out or inserted from the tank car mouth.When source of the gas or gas motor 1 go wrong, can use the manual input square shaft 8 on the hand worm reducer 4 of hand crank, gear 5 on worm reducer 4 output shafts is rotated, thereby order about tooth bar square shaft 7 up-and-down movement in orienting sleeve 6, trundle 11 and track 12 adopt the form of gear, tooth bar, solved the problem of skidding, made the dolly accurate positioning reliable.
