[0050] In order to better understand the purpose, structure and function of the present application, a two-liner trolley distributing device is described in further detail below in combination with the drawings.

[0051] Example 1

[0052] As Figures 1-2As shown, the two-lining trolley material distribution device of the present application comprises a rack 1, which is a rectangular frame composed of a steel frame structure, a translation track 3 is arranged on both sides above the rack 1, forming a space capable of sliding forward and backward above the rack 1, a swing track groove 2 is placed on the translation track 3, connected with the rack 1 through a lead screw 4, the lead screw 4 is parallel to the translation track 3, and the lead screw 4 is connected with the bottom of the swing track groove 2, in the process of driving the lead screw 4 to rotate, the swing track groove 2 is driven to move forward and backward on the translation track 3.

[0053] In use, the rack 1 is placed below the two-lining trolley, the forward and backward positions of the swing track groove 2 are adjusted by driving the lead screw 4, so as to facilitate the alignment of the discharge pipe 13 with the discharge ports at different positions in the horizontal direction of the two-lining trolley, and the concrete distribution operation is facilitated. The placement position of the rack 1 can be changed according to the site requirements, and it is not necessary to be strictly below the two-lining trolley, so as to leave more space below the two-lining trolley, facilitating the construction of other sections.

[0054] The swing track groove 2 is movably provided with a pump pipe support 6, which can swing on the swing track groove 2, so as to facilitate the alignment with the distribution ports on the two-lining trolleys at different heights. The discharge pipe 13 is installed on the end of the pump pipe support 6, and the discharge pipe 13 is communicated with the inlet pipe 9 fixed on the rack 1 through the telescopic pipe, so as to guide the concrete from the cement pump truck into the distribution ports on the two-lining trolley.

[0055] As shown in Figure 1 , 18 , 19 and 20, the telescopic pipe is composed of a first telescopic pipe 10, a second telescopic pipe 11, a third telescopic pipe 12, a fourth telescopic pipe 14 and a fifth telescopic pipe 15. The specific connection mode is: the inlet pipe 9 is connected with the first telescopic pipe 10, the first telescopic pipe 10 is connected with the second telescopic pipe 11 and forms the telescopic part of the telescopic pipe, according to the different lengths of the two-lining trolley, the first telescopic pipe 10 and the second telescopic pipe 11 are connected in different numbers of groups, forming the telescopic structure of the pipeline in the horizontal direction, one end of the third telescopic pipe 12 is connected with the nearest second telescopic pipe 11, the other end of the third telescopic pipe 12 is connected with the fourth telescopic pipe 14 arranged in the pump pipe support 6, the fourth telescopic pipe 14 is connected with a plurality of groups of first telescopic pipes 10 and second telescopic pipes 11, forming the telescopic part on the pump pipe support 6, one end of the fifth telescopic pipe 15 is connected with the nearest second telescopic pipe 11, and the other end is connected with the discharge pipe 13.

[0056] The pump pipe support 6 is a frame structure composed of four columns, and the fifth telescopic pipe 15 is movably arranged in the inside through the telescopic pipe fixing block 64.

[0057] As shown in Figures 7 to 11As shown, the specific structure of the first telescopic pipe 10, the second telescopic pipe 11, the third telescopic pipe 12, the fourth telescopic pipe 14 and the fifth telescopic pipe 15 can be seen, which are different in elbow length and number. The design of such structure mainly guarantees: 1. the connection of the first telescopic pipe 10 and the second telescopic pipe 11 is coaxial with the inlet pipe 9 and the third telescopic pipe 12 in horizontal direction, ensuring the unfolding and contraction of the first telescopic pipe 10 and the second telescopic pipe 11 in horizontal direction; 2. the connection of the third telescopic pipe 12 and the fourth telescopic pipe 14 is at the center position of the swing track groove 2 of the pump pipe frame 6; 3. the fifth telescopic pipe 15 is still in the pump pipe frame 6 and extends and contracts along the central axis of the pump pipe frame 6 during the unfolding and contraction of the first telescopic pipe 10 and the second telescopic pipe 11 on the pump pipe frame 6, and the running position is stable and not affected by the vibration of the pump pipe frame 6 during the pumping of concrete.

[0058] As shown in Figure 12 The translation track 3 is provided with a support bracket 8, the two ends of the support bracket 8 are provided with track clamps 81 buckled with the translation track 3, and the upper side of the support bracket 8 is provided with a transverse limiting groove 82. Above the rack 1, the connection of the first telescopic pipe 10 and the second telescopic pipe 11 is fixed on the support bracket 8. The connection of the first telescopic pipe 10 and the second telescopic pipe 11 is arranged in the transverse limiting groove 82, which avoids the violent left and right swing of the connection during use, ensuring the safe operation of the equipment. The transverse limiting groove 82 is also provided with a fixing seat 83, which is clamped on the second telescopic pipe 11, ensuring that the second telescopic pipe 11 does not fall off the support bracket 8.

[0059] During the movement of the swing track groove 2, the third telescopic pipe 12 is pulled, which drives the unfolding of the first telescopic pipe 10 and the second telescopic pipe 11, and the support bracket 8 moves together on the rack 1, keeping the stable unfolding and contraction of the first telescopic pipe 10 and the second telescopic pipe 11 in horizontal direction.

[0060] The translation track 3 is provided with self-lubricating plastic 31, and the swing track groove 2 and the support bracket 8 are arranged on the self-lubricating plastic 31, which reduces the sliding resistance of the swing track groove 2 and the support bracket 8 on the translation track 3.

[0061] The swing track groove 2 has an arc groove 22, and semi-circular arc grooves 21 are provided on both sides of the groove wall. A drum 61 is provided in the middle of the pump pipe frame 6. The drum 61 is embedded in the semi-circular arc groove 21 on the swing track groove 2 and can rotate on the semi-circular arc groove 21. One end of the pump pipe frame 6 is set in the arc groove 22. One end of the fourth telescopic tube 14 is connected to the second telescopic tube 11, and the other end passes through the center of the drum 61 and is connected to the third telescopic tube 12. During the rotation of the pump pipe frame 6 around the drum 61, the fourth telescopic tube 14 also rotates on the third telescopic tube 12 at the same time. For the limiting of the pump pipe frame 6, a hole can be drilled in the swing track groove 2, and a pin can be used to fix the groove wall of the swing track groove 2 to one end of the pump pipe frame 6 in the arc groove 22. As this is a mature technology, it will not be described in detail here.

[0062] In operation, first place the platform 1 under the secondary lining trolley, drive the screw 4 to adjust the front and back position of the swing track groove 2, align the discharge pipe 13 with the material placement port on the secondary lining trolley, rotate the pump pipe frame 6 to align the discharge pipe 13 with the material placement port on the secondary lining trolley, fix the pump pipe frame 6, and simultaneously adjust the length of the discharge pipe 13 extending out of the pump pipe frame 6 so that the discharge pipe 13 extends into the discharge port on the secondary lining trolley. After the material for one port is completed, retract the discharge pipe 13, drive the screw 4 to adjust the front and back position of the swing track groove 2 to align the discharge pipe 13 with the next material placement port, and extend the discharge pipe 13 to repeat the material placement operation. After the material placement port in the same horizontal direction is completed, rotate the pump pipe frame 6 to align with the material placement port of the other layer and repeat the operation until the concrete between the secondary lining trolley and the tunnel wall is completely filled.

[0063] Example 2

[0064] like Figures 4-6 As shown, in this embodiment, the discharge pipe 13 is a rubber hose. The rubber hose can greatly facilitate the adjustment and alignment, and ensure that the discharge pipe 13 can pass through the main structure of the secondary lining trolley and smoothly enter the material feeding port in a complex operating environment.

[0065] The discharge pipe 13 is equipped with a discharge port limiter 7, which has a discharge pipe fixing ring 72 and a support leg 73. The fixing ring 72 is fitted onto the discharge pipe 13. The support leg 73 is equipped with a sliding groove 74, which is slidably fixed onto the discharge port limiter 7 by a number of limiting clips 75 provided on the discharge port limiter 7.

[0066] The limiting head 75 is provided with a first limiting tooth 77, which cooperates with the second limiting tooth 78 provided on the buckle plate 76. The buckle plate 76 is movably connected to the buckle post 710 provided on the feed port limiter 7. The buckle post 710 is movably connected with a pressure plate 79, and the outer dimensions of the connection between the pressure plate 79 and the buckle post 710 gradually change.

[0067] The end of the support leg 73 is provided with a locking head 711. During use, first adjust the length of the support leg 73 extending out of the limiter 7 until the locking head 711 is pressed against the edge of the material outlet of the second lining trolley. Then lock the pressure plate 79 so that the first limiting tooth 77 and the second limiting tooth 78 are engaged to keep the position of the discharge pipe 13 fixed.

[0068] Example 3

[0069] like Figure 3 As shown, in this embodiment, a transverse frame 16 is movably provided on both sides of the platform 1, and a hydraulic telescopic rod is connected between the transverse frame 16 and the platform 1. The extension and retraction of the hydraulic telescopic rod can control the raising and lowering of the transverse frame 16. When the transverse frame 16 is lowered, the platform 1 can be raised, which can provide support to prevent the platform 1 from tipping over and facilitate the transverse movement of the platform 1.

[0070] Both the test stand 1 and the transverse frame 16 are equipped with rollers 5. The rollers 5 on the test stand 1 are oriented towards the axial direction of the test stand 1, and the rollers 5 on the transverse frame 16 are oriented towards the radial direction of the test stand 1, so that the test stand 1 can move left, right, forward and backward.

[0071] Example 4

[0072] like Figure 13 and 14 As shown, in this embodiment, the fixing base 83 consists of a fixing semi-circular ring 831 and a clip and semi-circular ring 832. One end of the fixing semi-circular ring 831 and the clip and semi-circular ring 832 are movably connected, and one end of the clip and semi-circular ring 832 can rotate around the fixing semi-circular ring 831. A T-shaped clip head 834 is connected to the clip and semi-circular ring 832 via a hinge seat 833. The fixing semi-circular ring 831 is provided with a limiting ear plate 835, and the limiting ear plate 835 is provided with a locking hole 836. The T-shaped clip head 834 engages with the limiting ear plate 835 to lock the fixing semi-circular ring 831 and the clip and semi-circular ring 832. A pin or wire is used to pass through the locking hole 836 and the T-shaped clip head 834 to connect the two structures together, preventing the T-shaped clip head 834 from falling off the limiting ear plate 835.

[0073] The technical solution of this embodiment can greatly facilitate the disassembly of the second telescopic tube 11.

[0074] Example 5

[0075] like Figure 17 As shown, in this embodiment, limiting discs 63 are connected to both sides of the drum 61. The diameter of the limiting discs 63 is larger than that of the drum 61, which can maintain the axial stability of the drum 61 and reduce the collision with the swing track groove 2. A gear 62 is connected to the drum 61, and a rack 23 matching the gear 62 is provided in the arc groove 22. The gear 62 is connected to the drive motor, and the rotation of the gear 62 controls the position of the pump pipe bracket 6.

[0076] Meanwhile, the swing track groove 2 is equipped with a clamp 24 that engages with the limiting disc 63. The clamp 24 is arc-shaped and holds the limiting disc 63 in place to prevent the pump pipe frame 6 from falling off the swing track groove 2. A counterweight 65 is also connected to the drum 61 to balance the weight at both ends of the pump pipe frame 6.

[0077] like Figure 21 and 22 As shown, according to claim 9, the lining trolley fabric placement device is characterized in that the fixing block 64 is U-shaped, with its top perimeter embedded in the gaps between the columns of the pump pipe frame 6, thereby engaging with the four columns of the pump pipe frame 6. The fifth telescopic tube 15 extends from the top and sides of the fixing block 64. The fixing block 64 maintains the stability of the fifth telescopic tube 15 as it runs on the pump pipe frame 6.
