Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment for tunnel construction, in particular to a wind storage cylinder crane for a shield machine. Background Technique

[0002] The construction of a shield machine cannot do without ventilation. The ventilation method usually sets up a fan at the wellhead of the launching shaft or the ventilation shaft and transports it to the tunneling position of the shield machine through an air duct. The air duct includes the ventilation pipeline of the shield machine trolley and the tunnel ventilation pipeline. Since the shield machine is constantly advancing, between the shield machine and the tunnel ventilation pipeline, it is necessary to use a wind storage cylinder device to facilitate the extension of the pipeline. When connecting, it is necessary to transport the wind storage cylinder filled with ventilation hoses from the ground to the tail of the shield machine, and then use a crane to lift the used empty wind storage cylinder off the top of the trolley and replace it with a full one. After the staff fixes the new tunnel ventilation hose to the ventilation hose leading to the wellhead, it can be used.

[0003] The existing wind storage cylinder lifting equipment mainly uses multiple electric winches to cooperate for lifting. During the lifting process, due to the asynchronous operation of the winches, it is easy to shake, and it takes a lot of time for each winch to cooperate with each other. For example, in the prior art: a multi-degree-of-freedom wind storage cylinder lifting device for a shield machine (application number: 202210374601.3) transports the wind storage cylinder through an electric hoist, a driving walking wheel and a front frame. In this structure, due to the complexity of the equipment, the lifting time is relatively long.

[0004] Therefore, it is necessary to design a wind storage cylinder crane with high lifting efficiency and easy operation. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wind storage cylinder crane for a shield machine to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wind storage cylinder crane for a shield machine includes:

A horizontal support rib plate is arranged on the air storage cylinder, and the horizontal support rib plate is located at the lower part of the air storage cylinder. The support base cooperates with the horizontal support rib plate to provide adjustable support for the air storage cylinder.

[0012] As a further solution of the present utility model: It further includes a crane main oil cylinder. There are two crane main oil cylinders which are symmetrically fixed on both sides of the upper frame at one end of the air storage cylinder bracket. The crane main oil cylinder includes a double-groove guide wheel, a cable fixing seat, a lifting cable, and a telescopic rod.

[0013] Wherein the double-groove guide wheel is fixedly connected to one end of the telescopic rod, and the cable fixing seat is fixed on the air storage cylinder bracket, and the hole position for fixing the cable is at the same height as the double-groove guide wheel.

[0014] One end of the lifting cable is fixed in the middle of the cable fixing seat, surrounds the double-groove guide wheel, and the other end of the lifting cable is connected to the cylindrical pin on the horizontal support rib plate.

[0015] As a further solution of the present utility model: It further includes a shunt guide wheel. A lifting guide wheel is arranged at the bottom of the cable rack. The lifting cable surrounds the shunt guide wheel and then winds around the lifting guide wheel and is connected to the cylindrical pin on the horizontal support rib plate.

[0016] As a further solution of the present utility model: The support base is horizontally arranged on the air storage cylinder bracket, and the top of the support base abuts against the horizontal support rib plate.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 6, in the embodiment of the present utility model, a wind storage cylinder crane for a shield machine includes a wind storage cylinder support 1, a wind storage cylinder 2, a main crane cylinder 3, a cable rack 4, a maintenance platform 5, and a maintenance ladder 6. The wind storage cylinder support 1 is fixed on the ramp trolley at the tail of the shield machine. There are two main crane cylinders 3, which are symmetrically fixed on both sides of the upper frame at one end of the wind storage cylinder support 1. There are four cable racks 4, which are symmetrically distributed and fixedly connected to both sides of the wind storage cylinder support 1. Both the maintenance platform 5 and the maintenance ladder 6 are fixedly connected to the wind storage cylinder support 1. The maintenance ladder 6 is connected to the support legs on both sides at one end of the wind storage cylinder support 1, and the maintenance platform 5 is connected to the upper surface at one end of the wind storage cylinder support 1 away from the maintenance ladder 6.

[0031] Four support seats 101 are rotatably connected to the inner side of the upper part of the wind storage cylinder support 1 through pin shafts. The support seats 101 here can rotate along the pin shafts. When the support seats 101 for hoisting the wind storage cylinder 2 hinder the hoisting process, the support seats 101 can be rotated and received inside the wind storage cylinder support 1. When the wind storage cylinder 2 is hoisted to a proper position, the support seats 101 are rotated to the lower part of the wind storage cylinder 2 to support the entire wind storage cylinder 2.

[0032] The main body of the wind storage cylinder 2 is of a cylindrical barrel structure, and a plurality of horizontal support rib plates 201 are fixedly connected to the lower part of the barrel body and adjacent rib plates are connected in series through cylindrical pins 202. The arrangement of the horizontal support rib plates 201 turns the bottom of the entire wind storage cylinder 2 into a plane, which is more convenient for the support seats 101 to support the wind storage cylinder 2. At the same time, the cylindrical pins 202 can facilitate the fixing of the hoisting cable 303.

[0033] The main crane cylinder 3 includes a double-groove guide wheel 301, a cable fixing seat 302, and a hoisting cable 303. Among them, the double-groove guide wheel 301 is fixedly connected to the front end of the telescopic rod 304 of the main crane cylinder 3. The cable fixing seat 302 is fixed on the support leg of the wind storage cylinder support 1, and the hole position for fixing the cable is at the same horizontal line and the same height as the double-groove guide wheel 301. One end of the hoisting cable 303 is fixed to the middle of the cable fixing seat 302, surrounds the double-groove guide wheel 301 and the cable rack 4, and the other end is connected to the cylindrical pin 202 on the horizontal support rib plate 201. The oil circuit of the main crane cylinder 3 is connected to the same oil supply pump station.

[0034] A hoisting guide wheel 401 is arranged at the bottom of the cable rack 4, and a flow-dividing guide wheel 402 is fixedly connected to the side surface of the upper frame of the wind storage cylinder support 1. There are two coaxial groove wheels inside the flow-dividing guide wheel 402. The hoisting cable 303 surrounds the flow-dividing guide wheel 402 and then winds around the hoisting guide wheel 401 upward, and then is connected to the cylindrical pin 202 on the horizontal support rib plate 201.

[0035] The working principle of the present utility model is:

[0036] When the utility model works, first, the air storage cylinder 2 filled with ventilation hoses is transported from the ground to the tunneling position of the shield machine. Then, the non-fixed end of the hoisting cable 303 is passed through the cylindrical pin 202 on the horizontal support rib plate 201 of the air storage cylinder 2. After that, the main cylinders 3 of the two cranes are synchronously supplied with oil by the oil supply pump station to extend the cylinders, so that the non-fixed end of the hoisting cable 303 descends to an appropriate height. Then, under the action of the contraction of the cylinders, the hoisting cable 303 pulls the entire air storage cylinder 2 upward to above the air storage cylinder support 1. After the air storage cylinder 2 reaches the appropriate position, the cylinders are controlled to stop contracting. Then, the staff enters the maintenance platform 5 through the maintenance ladder 6 and rotates the support seat 101 to directly below the air storage cylinder 2, and extends the main cylinders 3 of the crane to gently place the horizontal support rib plate 201 at the bottom of the air storage cylinder 2 on the support seat 101 to complete the hoisting work of the entire air storage cylinder 2. During the hoisting process, the double-groove guide wheel 301, the hoisting guide wheel 401, and the flow-dividing guide wheel 402 play a guiding and flow-dividing role for the hoisting cable 303 to prevent the cables from being wound around each other and causing the air storage cylinder 2 to shake during the hoisting process.
