Technical Field

[0001] The utility model belongs to the technical field of seal grease application, and particularly relates to a shield tail seal grease application device for shield starting. Background Art

[0002] With the wide application of shield tunneling technology in subway construction, mine tunnels, river-crossing tunnels and other underground buildings, the shield construction technology has become increasingly mature. At the same time, in the face of complex strata, major construction risk factors have also increased. The shield tail seal device is a key component in the shield tunnel and plays an important role in the shield construction process. To ensure good sealing effect of the shield machine in subsequent construction, before starting, manual application of shield seal grease is required to fill the gap of the shield tail brush to ensure the sealing effect.

[0003] At present, the application of shield tail seal grease is basically completed manually, that is, manually stuffing the seal grease into the wire brush at the shield tail of the shield machine for application. Since the wires of the shield tail brush are relatively dense and hard, and the space is narrow, it is easy to scratch the hand during the application process, and at the same time, the application efficiency is low; in addition, the shield machine is huge, and when applying grease, workers need to climb up and down to change the position of applying the shield tail seal grease, with large labor intensity and insufficient safety.

[0004] Therefore, an improved technical solution is needed to address the above deficiencies of the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shield tail seal grease application device for shield starting, so as to solve the technical problems of inconvenient operation, low application efficiency and large labor intensity when manually applying shield tail seal grease to the wire brush at the shield tail of the shield machine before the shield machine starts.

[0006] In order to achieve the above purpose, the shield tail seal grease application device of the utility model provides the following technical solutions:

[0007] A shield tail seal grease application device for shield starting, comprising:

[0008] A storage cylinder for containing the shield tail seal grease to be applied;

[0009] A pumping component connected to the storage cylinder and used to convey the shield tail seal grease out of the storage cylinder;

[0010] A conveying pipeline, one end of which is connected to the pumping component, and the other end is provided with an oil outlet nozzle for applying the shield tail seal grease at a set position;

[0012] The operating rod, one end of the operating rod is connected to the oil outlet nozzle, and the other end is provided with an operating handle.

[0013] As a further optimized technical solution, the oil outlet nozzle has an integrally connected installation section and a spraying section. The installation section is fixedly connected to the conveying pipeline. The spraying section is in a fan shape, and the width of the spraying section gradually increases from one end close to the installation section to the extending direction away from the spraying section, and the thickness of the spraying section gradually decreases from one end close to the installation section to the extending direction away from the spraying section.

[0014] As a further optimized technical solution, an installation ring is fixedly connected to the top of the operating rod. The installation ring is sleeved on the installation section and is rotatably and fixedly connected to the installation section.

[0015] As a further optimized technical solution, clamping grooves are circumferentially spaced on the outer side wall of the installation section, and clamping blocks are arranged on the inner side wall of the installation ring. Rotating the installation ring or the oil outlet nozzle can make the clamping blocks be clamped in different clamping grooves to realize the rotatable and fixed connection between the installation ring and the installation section.

[0016] As a further optimized technical solution, the bottom of the support base has universal wheels, and a protective cover is arranged on the top of the support base. The protective cover is used to cover the storage cylinder and the pumping components.

[0017] As a further optimized technical solution, the top of the protective cover has a push and pull handle ring.

[0018] As a further optimized technical solution, a fixed column is arranged on the support base. The fixed column vertically supports the top of the base and is used to install the conveying pipeline.

[0020] As a further optimized technical solution, the bottom of the stop baffle has a stud section, and the top of the corresponding fixed column has a threaded hole adapted to the stud section. The stud section is in threaded fit with the threaded hole.

[0021] As a further optimized technical solution, the operating rod is of a telescopic rod structure and is used to adjust the height of applying the tail seal grease.

[0022] Beneficial effects: When applying tail seal grease to the wire brush at the tail of the shield machine before the shield machine starts, by manually holding the operating rod, inserting the oil outlet nozzle into the steel brush where the grease needs to be coated, and then starting the pumping component, the tail seal grease in the storage cylinder is transported to the steel brush through the conveying pipeline. By changing the position of the oil outlet nozzle, the position of the tail seal grease coating can be changed. Compared with the manual application of tail seal grease in the prior art, the operation is very convenient, and it is not necessary for the operator to climb up and down on the shield machine to change the position of the coated grease, effectively improving the working efficiency and safety of the grease coating.

[0032] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0033] The present utility model provides a shield tail seal grease application device for shield starting, which replaces manual application of shield tail seal grease at the wire brush of the shield machine, is very convenient to operate, and improves the safety of grease application.

[0034] Embodiment 1

[0035] As Figure 1 、 Figure 2 shown, the shield tail seal grease application device for shield starting includes a storage cylinder 1, a pumping component 2, a conveying pipeline 3, a support base 4 and an operating rod 5.

[0036] The storage cylinder 1 has a cylindrical structure and an accommodation cavity inside for containing the shield tail seal grease to be applied. The pumping component 2 is connected to the storage cylinder 1 and is used to convey the shield tail seal grease out of the storage cylinder 1 for application. In this embodiment, the pumping component 2 can be a grease pump, and in other embodiments, other types of pump equipment can also be selected. One end of the conveying pipeline 3 is connected to the pumping component 2, and an oil outlet nozzle 6 is fixedly communicated at the other end for applying the shield tail seal grease to a set position. In order to prevent the grease in the conveying pipeline 3 from flowing out of the oil outlet nozzle 6 after the pumping component 2 stops working, a manual ball valve 8 can be installed at a position of the conveying pipeline 3 close to the oil outlet nozzle 6. In this way, when the device is not in working condition, the manual ball valve 8 can be closed, so that the residual grease in the conveying pipeline 3 can be sealed in the inner cavity of the conveying pipeline 3.

[0037] In this embodiment, as Figure 3 、 Figure 5As shown, the oil outlet nozzle 6 has an integrally connected installation section 601 and a spraying section 602. The installation section 601 is fixedly connected to the conveying pipeline 3. The spraying section 602 is in a fan shape. The width of the spraying section 602 gradually increases from the end close to the installation section 601 in the extending direction away from the spraying section 602, and the thickness of the spraying section 602 gradually decreases from the end close to the installation section 601 in the extending direction away from the spraying section 602. In this way, the spraying section 602 has a flat nozzle structure, which is convenient for inserting into the inside of the steel brush; the wider spraying port can ensure the spraying amount of the grease.

[0038] The support base 4 is arranged at the bottom of the storage cylinder 1 and the pumping component 2 for jointly supporting the storage cylinder 1 and the pumping component 2. In this embodiment, the bottom of the support base 4 is provided with universal wheels 9, so as to facilitate the transfer of the position of this device. In addition, a protective cover 10 is fixedly connected to the top of the support base 4. The protective cover 10 is a cylindrical structure with an open bottom end, and is installed upside down on the top of the support base 4 and covers the storage cylinder 1 and the pumping component 2 for protecting the storage cylinder 1 and the pumping component 2. At the same time, in order to facilitate the handling and pushing and pulling of this device, a push handle ring 11 is provided on the top of the protective cover 10.

[0039] One end of the operating rod 5 is connected to the oil outlet nozzle 6, and the other end is provided with an operating handle 501, which is convenient for the operator to hold the operating handle 501 to change the oil outlet position of the oil outlet nozzle 6.

[0040] Furthermore, an installation ring 7 is fixedly connected to the top of the operating rod 5. The installation ring 7 is sleeved on the installation section 601 and is rotatably and fixedly connected to the installation section 601. In this way, the oil outlet angle of the oil outlet nozzle 6 can be adjusted according to the needs of the specific position.

[0041] Specifically, a clamping groove 603 is circumferentially and spacedly arranged on the outer side wall of the installation section 601, and a clamping block 701 is arranged on the inner side wall of the installation ring 7. Rotating the installation ring 7 or the oil outlet nozzle 6 can make the clamping block 701 be clamped in different clamping grooves 603 to realize the rotatable and fixed connection between the installation ring 7 and the installation section 601.

[0042] In order to further improve the convenience of operation, the operating rod 5 is selected as a common telescopic rod structure, so that the specific length of the operating rod 5 can be adjusted according to the coating height of the shield tail seal grease.

[0043] Furthermore, since the conveying pipeline 3 is relatively long as a whole and is not convenient to move and store, to solve this problem, a fixed column 12 is arranged on the support base 4. The fixed column 12 vertically supports the top of the support base 4. When this device is not in use, the whole conveying pipeline 3 can be wound around the fixed column 12. When in use, the appropriate length of the conveying pipeline 3 can be released from the fixed column 12 according to the specific needs. In this way, when moving this device, the conveying pipeline 3 can be wound around the fixed column 12 again, which is also convenient for the overall movement of the conveying pipeline 3.

[0044] Furthermore, after a large number of conveying pipelines 3 are wound around the fixed column 12, it is possible that multiple turns of the conveying pipeline 3 may fall off from the top of the fixed column 12. To avoid this situation, a stop baffle 13 is detachably connected to the top of the fixed column 12. The radial dimension of the stop baffle 13 is larger than the radial dimension of the fixed column 12 to block the conveying pipeline 3.

[0045] Specifically, a stud section 14 is provided at the bottom of the stop baffle 13, and a threaded hole 15 adapted to the stud section 14 is provided at the middle position of the top of the fixed column 12. The stud section 14 is in threaded cooperation with the threaded hole 15. The stop baffle 13 can be detached when winding the conveying pipeline 3, so as to facilitate winding the conveying pipeline 3 around the top of the fixed column 12. After winding is completed, the stop baffle 13 is installed on the top of the fixed column 12 to block the conveying pipeline 3.

[0046] It can be understood that the above description is only exemplary, and the embodiments of the present application do not limit this.

[0047] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
