Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, specifically to a mortar tank return device for a tunnel boring machine. Background Technology

[0002] After the cutterhead excavation of a full-face hard rock tunnel boring machine (TBM) is completed, shotcrete support needs to be applied to the formed tunnel walls in a timely manner. Typically, the concrete mortar used for support needs to be loaded into containers outside the tunnel and transported to the excavation position via a transport train. It is then moved to the mortar tank support pre-installed on the TBM's auxiliary trolley for use in shotcrete support. Once the mortar inside the tank is depleted, it needs to be transported back outside the tunnel and refilled with concrete mortar.

[0003] Currently, the main method for moving mortar containers from the transport train to a pre-reserved position on the trolley behind the tunnel boring machine (TBM) and returning empty mortar containers to the transport train is by crane. This method is only suitable for tunnel construction where the internal space is relatively large and the demand for concrete mortar is relatively small. If the demand for concrete mortar is large and the tunnel space is confined, the mortar containers need to be larger. The confined space cannot provide an effective lifting height, and the crane lifting method cannot meet the requirements. Therefore, there is an urgent need to design a device that can stably move mortar containers between the transport train and the mortar container support on the trolley behind the TBM in confined spaces to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a mortar tank return device for tunnel boring machines, so as to solve the problem of difficulty in moving mortar tanks in confined spaces in the prior art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A mortar tank positioning device for a tunnel boring machine includes a mortar tank, a transport train, a lever, a lever support frame, and a mortar tank support frame.

[0007] The mortar tank support frame is fixed on the rear trolley of the tunnel boring machine;

[0008] The lever support frame is located above the mortar tank support frame and is rotatably connected to the upper frame of the shield machine's rear trolley via a drive mechanism;

[0009] The lever is rotatably connected to the lever support frame via a cylindrical pin;

[0010] The mortar tank is placed above the transport train on the rear trolley of the tunnel boring machine;

[0011] When the lever rotates to a perpendicular angle with the lever support frame, the lever support frame is moved along the upper frame of the shield machine's rear trolley by the drive mechanism. At this time, the lever support frame drives the lever to move the mortar tank from the transport train to the mortar tank support frame.

[0012] As a further embodiment of this utility model: multiple sets of movable rollers are evenly provided at the bottom of the mortar tank, and the movable rollers can rotate freely around the roller axis.

[0014] As a further aspect of this utility model: the Shore hardness of the rubber buffer pad is 50A-70A, and the thickness is 20mm-40mm.

[0015] As a further embodiment of this utility model: the driving mechanism includes a driving motor disposed at both ends of the lever support frame, a first roller is sleeved on the output shaft end of the driving motor, and the output shaft end is connected to the driven shaft through a transmission belt. The driven shaft is rotatably connected to the lever support frame, and a second roller is sleeved on the end of the driven shaft.

[0019] As a further embodiment of this utility model: a roller transition plate is fixed on the side of the mortar tank support frame near the transport formation.

[0020] As a further embodiment of this utility model: the roller transition plate is flush with the upper surface of the mortar tank support frame, and the surface is provided with anti-slip texture.

[0021] The beneficial effects of this utility model are:

[0022] (1) This application adopts a lever and a movable lever support frame design, which can meet the requirements of moving the mortar tank from the transport train to the mortar tank support frame for use.

[0033] Please see Figures 1 to 4 As shown, this utility model is a mortar tank positioning device for a tunnel boring machine (TBM), including a mortar tank 1, a transport train 2, a lever 3, a lever support frame 4, and a mortar tank support frame 5. The mortar tank support frame 5 is fixed on the rear trolley of the TBM. The lever support frame 4 is located above the mortar tank support frame 5 and is rotatably connected to the upper frame of the rear trolley of the TBM through a drive mechanism. The lever 3 is rotatably connected to the lever support frame 4 through a cylindrical pin 302. The mortar tank 1 is placed above the transport train 2 on the rear trolley of the TBM. When the lever 3 rotates to a perpendicular angle with the lever support frame 4, the drive mechanism moves the lever support frame 4 along the upper frame of the rear trolley of the TBM. At this time, the lever support frame 4 drives the lever 3 to move the mortar tank 1 from the transport train 2 to the mortar tank support frame 5.

[0034] During the use of the repositioning device of this application, the mortar tank 1 is first filled with concrete mortar outside the tunnel excavated by the tunnel boring machine, and then hoisted onto the transport train 2. The transport train 2 then transports the mortar tank 1 to the rear trolley corresponding to the mortar tank support frame 5. The drive mechanism drives the lever support frame 4 to move as a whole to the position on the upper edge of the rear trolley that ensures the lever 3 can work normally. When the lever 3 rotates to a perpendicular angle with the lever support frame 4, the drive mechanism drives the lever support frame 4 to move towards the mortar tank support frame 5, which in turn drives the lever 3 to move the mortar tank 1 towards the mortar tank support frame 5 until it reaches the predetermined position. At this time, the mortar tank 1 can supply concrete mortar. After the mortar is used up, the action of moving the mortar tank 1 is repeated to move the empty mortar tank 1 back onto the empty transport train 2 and transport it outside the tunnel excavated by the tunnel boring machine to refill with concrete mortar, and then it is transported back into the tunnel.

[0035] When the space inside the tunnel is narrow, the crane cannot provide sufficient lifting height. This application adopts the design of lever 3 and movable lever support frame 4, which can meet the requirements of moving mortar tank 1 from transport train 2 to mortar tank support frame 5 for use. This eliminates the need for hoisting equipment, adapts to the narrow tunnel environment, avoids shaking of the tank due to hoisting, thereby reducing the risk of collision and improving the safety of transferring mortar tank 1.

[0036] In this specific embodiment, multiple sets of movable rollers 101 are evenly provided at the bottom of the mortar tank 1. The movable rollers 101 can rotate freely around the roller axis. During the operation of moving the mortar tank 1, the design of the movable rollers 101 at the bottom of the mortar tank 1 can reduce the friction between the mortar tank 1 and the contact surface of the transport train 2, so that the mortar tank 1 can be moved quickly and effortlessly by using the lever 3.

[0037] In this specific embodiment, buffer pads 201 are provided at both ends of the side of the transport train 2 away from the mortar tank support frame 5, and rubber buffer pads are provided on the contact surface between the buffer pads 201 and the mortar tank 1; multiple stop pins 202 are evenly distributed on the other side of the transport train 2; the Shore hardness of the rubber buffer pads is 50A-70A, and the thickness is 20mm-40mm; when the mortar tank 1 is fully loaded and placed on the transport train 2, the stop pins 202 can prevent the mortar tank 1 from falling off the transport train 2 due to vibration or lateral tilting during transportation. After the fully loaded mortar tank 1 arrives at the position of the mortar tank support frame 5 with the transport train 2, the stop pins 202 can be pulled out, thereby ensuring that the mortar tank 1 can be smoothly moved.

[0038] In this specific embodiment, the driving mechanism includes drive motors 401 installed at both ends of the lever support frame 4. A first roller is fitted onto the output shaft of the drive motor 401, and the output shaft is connected to a driven shaft via a transmission belt. The driven shaft is rotatably connected to the lever support frame 4, and a second roller is fitted onto the end of the driven shaft. The first and second rollers move along the guide rails of the upper frame of the rear trolley of the tunnel boring machine. The drive motors 401 at both ends of the lever support frame 4 operate synchronously via a synchronous controller. When the drive mechanism moves the lever support frame 4 and the lever 3, the drive motors 401 at both ends of the lever support frame 4 can operate synchronously. The synchronous operation of the drive motors 401 ensures stable overall movement of the lever support frame 4, guaranteeing uniform force when the lever 3 moves the mortar tank 1. When the drive mechanism is designed, the drive motors 401 are turned on, and the output shaft drives the driven shaft to rotate, causing the first and second rollers to move along the guide rails of the upper frame of the rear trolley of the tunnel boring machine.

[0039] In this specific embodiment, the upper middle part of the lever 3 is rotatably connected to the lever support frame 4 via the extension cylinder 301; the cylinder body of the extension cylinder 301 is hinged to the lever support frame 4, and the piston rod is hinged to the upper middle part of the lever 3. This application can rotate the lever 3 to a perpendicular angle with the lever support frame 4 via the extension cylinder 301 to facilitate the operation of the mortar tank 1. When the lever 3 is rotated by the extension cylinder 301 and moves closer to the lever support frame 4, it can prevent workers from bumping into things and causing safety problems.

[0040] In this specific embodiment, a roller transition plate 501 is fixed on the side of the mortar tank support frame 5 near the transport train 2; the roller transition plate 501 is flush with the upper surface of the mortar tank support frame 5 and has anti-slip texture on the surface; the roller transition plate 501 between the mortar tank support frame 5 and the transport train 2 can reduce the gap between the mortar tank 1 moving from the transport train 2 to the mortar tank support frame 5, thereby reducing the risk of the mortar tank 1 tilting and overturning.

[0041] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
