Description

Technical Field

[0001] This utility model relates to the field of shield machine tail brush technology, specifically a hydraulic tail brush grease filling mechanism. Background Technology

[0002] The tail brush of a tunnel boring machine (TBM) is an important component used to clean and lubricate the tunnel walls during the tunneling process. Normally, grease is added to the tail brush by a push pump, which draws grease from a storage container or lubrication system and delivers it to the parts that need lubrication.

[0003] However, in the existing technology, the conveyor plate is fixedly connected to the entire system and cannot be disassembled. This makes it difficult to add grease to the inside of the storage cylinder after the conveying work is completed, as the operating space is small and it is not easy to clean the residual grease. Therefore, there is an urgent need for a change. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a hydraulic tail brush grease filling mechanism, which solves the problems mentioned in the background art.

A linear moving component is fixedly installed on the outer wall of the storage cylinder. The linear moving component drives the conveying disc to move vertically through the bracket to deliver grease to the tail brush of the tunnel boring machine.

[0008] The bracket is fixedly installed on the conveyor tray. Slots are provided on both sides of the bracket. A plug is fixedly connected to the top of the conveyor tray. When the conveyor tray is installed, the plug is inserted into the slot and locked to the slot by bolts.

[0015] 1. In this utility model, the conveyor plate and the bracket are installed in a detachable manner.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a hydraulic tail brush grease filling mechanism, including a storage cylinder 1, a conveying disc 8 that can move vertically along the inner wall of the storage cylinder 1, and a bracket 7 that can be detachably installed on the top of the conveying disc 8. A linear moving component is fixedly installed on the outer wall of the storage cylinder 1. The linear moving component drives the conveying disc 8 to move vertically through the bracket 7 to deliver grease to the tail brush of the tunnel boring machine.

[0025] The bracket 7 is fixedly installed on the conveyor plate 8. Slots 701 are provided on both sides of the bracket 7. A plug 9 is fixedly connected to the top of the conveyor plate 8. When the conveyor plate 8 is installed, the plug 9 is inserted into the slot 701, and the plug 9 and the slot 701 are locked together by bolts 10.

[0026] The conveyor plate 8 and the bracket 7 are installed in a detachable manner. When it is necessary to add grease to the inside of the storage cylinder 1, the conveyor plate 8 should first be moved to the highest point of the storage cylinder 1, and then the bolt 10 should be loosened to remove the insert 9 from the slot 701 to disassemble the conveyor plate 8. At this time, the space above the storage cylinder 1 is increased, which makes it easier to add grease and also allows for the cleaning of dried residual grease.

[0027] Specifically, the linear motion assembly includes two support rods 2 fixed to the side wall of the storage cylinder 1, a top plate 3 fixed to the top of the support rods 2, and a power element set on the top plate 3.

[0028] The power components include a motor 4 fixed to the top of the top plate 3, a lead screw 5 fixed to the output end of the motor 4, a nut strip 6 threaded onto the lead screw 5, the upper end of the bracket 7 being fixedly connected to the nut strip 6, a guide groove 201 being provided on the side wall of the support rod 2, and both ends of the nut strip 6 being slidably disposed in the guide groove 201 provided on the side wall of the support rod 2.

[0029] When conveying grease, motor 4 is started first, which drives screw 5 to rotate. Screw 5 drives nut bar 6 to descend. Nut bar 6 drives conveyor disc 8 to descend through bracket 7, so that conveyor disc 8 pushes the grease inside storage cylinder 1, so that the grease covers the tail brush. The tail brush cleans and lubricates the tunnel wall. Adding grease can reduce friction, reduce wear of parts, and extend the service life of the sealing system. Appropriate grease can improve the sealing performance of the sealing system, fill sealing gaps, prevent mud or water from leaking out from the gaps in the sealing system, and maintain the sealing effect of the tunnel boring machine.

[0030] In addition, an infrared transmitter 11 is fixedly connected to the bottom of the nut strip 6, an infrared receiver 12 is embedded on the support rod 2, and a controller 13 and a sound alarm 14 are fixedly installed on the support rod 2. The infrared receiver 12 and the sound alarm 14 are both electrically connected to the controller 13. The electrical connection method here is existing technology. The sound alarm 14 can be of model YS-01H.

[0031] Motor 4 drives lead screw 5 to rotate, and lead screw 5 drives nut bar 6 to descend. When the infrared transmitter 11 at the bottom of nut bar 6 moves to infrared receiver 12, the infrared light emitted by infrared transmitter 11 is received by infrared receiver 12. Infrared receiver 12 sends the signal to controller 13, controller 13 transmits the signal to sound alarm 14, sound alarm 14 sounds to remind the staff. At this time, the grease in storage cylinder 1 is consumed and needs to be added; at this time, controller 13 will also control motor 4 to stop.

[0032] A discharge pipe 15 is fixedly connected to the side wall of the storage cylinder 1 for discharging grease from the storage cylinder 1. The discharge pipe 15 is located near the bottom edge of the storage cylinder 1.
