A kind of shield tail grease injection control system, including ground air compressor machine, partial pressure joint, vacuum air bag, tunnel air compressor machine
And grease pump, the ground air compressor machine connected with the vacuum air bag and the tunnel air compressor machine respectively by the partial pressure joint
Connect, the tunnel air compressor machine, grease pump, shield tail are linked in sequence successively.
As the further improvement to above-mentioned technical proposal：
The shield tail grease injection control system also includes pressure ascending pipe, grease conveying supervisor and check-valves, the pressure
Power ascending pipe is connected between the tunnel air compressor machine and the grease pump, and the grease conveying supervisor is connected to the grease pump
Between the shield tail, the grease conveying supervisor is provided with the check-valves for preventing seal grease from flowing back.
The shield tail grease injection control system is also included for connecting the ground air compressor machine and the partial pressure joint
Pressure delivery main.
The shield tail grease injection control system also includes the deslagging penstock being connected with vacuum air bag.
Compared with prior art, the utility model has advantages below：
Shield tail grease injection control system of the present utility model is simple to operate, easy to maintenance, by ground air compressor machine and tunnel
Road air compressor machine co- controlling pressure, makes grease pump obtain the pressure of stabilization, so that in the light of actual conditions, by the seal grease of shield tail
Uniformly, lasting, stable, quantitative squeezes between shield tail brush, effectively control grease injection rate, it is easy to promotes practical, ensure that
Injection oil quality, it is ensured that the seal grease filling between shield tail brush is more uniform closely knit, it is ensured that the safety of production, increased
The service life of shield tail brush, improves efficiency of construction and safety coefficient.

Specific embodiment
The utility model is described further below with reference to the drawings and specific embodiments.
As shown in figure 1, a kind of shield tail grease injection control system, including ground air compressor machine 1, partial pressure joint 3, vacuum air bag
9th, tunnel air compressor machine 4 and grease pump 6, ground air compressor machine 1 are connected with vacuum air bag 9 and tunnel air compressor machine 4 respectively by partial pressure joint 3
Connect, tunnel air compressor machine 4, grease pump 6, shield tail（Not shown in figure）It is linked in sequence successively.Shield tail grease injection of the present utility model
Control system is simple to operate, easy to maintenance, by ground air compressor machine 1 and the co- controlling pressure of tunnel air compressor machine 4, makes grease pump 6
Obtain the pressure of stabilization so that in the light of actual conditions, by the seal grease of shield tail it is uniform, lasting, stable, quantitative squeeze into shield tail
Between brush, grease injection rate is effectively controlled, it is easy to promote practical, ensure that injection oil quality, it is ensured that between shield tail brush
Seal grease filling is more uniform closely knit, it is ensured that the safety of production, the service life of shield tail brush is increased, so that shield machine
Service life be effectively ensured, improve its competitiveness commercially, it is easy to promote, improve efficiency of construction and safety be
Number.
In the present embodiment, tunnel air compressor machine 4 uses small-sized air compressor, to be applicable the demand of small-sized shield tunnel.
In the present embodiment, shield tail grease injection control system also includes pressure ascending pipe 5, grease conveying supervisor 7 and non-return
Valve 8, pressure ascending pipe 5 is connected between tunnel air compressor machine 4 and grease pump 6, and grease conveying supervisor 7 is connected to grease pump 6 and shield
Between tail, grease conveying supervisor 7 is provided with the check-valves 8 for preventing seal grease from flowing back.
In the present embodiment, shield tail grease injection control system is also included for connecting ground air compressor machine 1 and partial pressure joint 3
Pressure delivery main 2.Pressure delivery main 2 is connected by starting well 11 with the partial pressure joint 3 in small-sized shield tunnel 12.
