Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a shield segment transportation platform. Background Technique

[0002] A shield machine is a tunnel boring machine using the shield method and is one of the main construction equipment for mountain tunnels, subways and other underground passages. While excavating the passage, it is necessary to lay concrete segments in the passage to support the passage and prevent the passage from collapsing. The laying of segments is mainly carried out by a rail vehicle to send the segments into the shield machine, and then the shield machine excavates the tunnel while laying segments, grouting and other operations.

[0003] When placing segments on the existing shield segment transportation platform, it mainly adopts the horizontal placement for stacking up and down and the vertical placement for stacking left and right. When using the stacking up and down method, it is necessary to place cushion blocks between the segments. Therefore, the operation during unloading will be more troublesome. Before the lifting structure lifts the segment, the staff needs to remove the cushion blocks, which is time-consuming and laborious. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a shield segment transportation platform to solve the technical problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a shield segment transportation platform, including a transport vehicle, both sides of the top of the transport vehicle are connected with brackets, and pulleys and ropes are connected inside the brackets. One end of the rope is connected with a cushion block, and a buffer sleeve is sleeved outside the cushion block. The other end of the rope is connected with a counterweight.

[0006] By adopting the above technical solution, when the segment body above the cushion block is removed, the cushion block and the buffer sleeve no longer receive the pressure generated by the weight of the segment body. At this time, the cushion block and the buffer sleeve end the limit. Then, the counterweight falls by gravity. After the counterweight falls, it pulls the cushion block through the rope, and at the same time, the pulley is used to prevent the rope from shifting, so as to move the cushion block and the buffer sleeve away from the top of the next segment body.

[0007] Further, the buffer sleeve is made of rubber material, and the top and bottom of the cushion block and the buffer sleeve are both arc-shaped.

[0008] By adopting the above technical solution, a segment body is placed on the cushion block through a lifting device, and then the cushion block is pressed by the weight of the segment body to prevent the cushion block from shifting, and the buffer sleeve is used for buffering to reduce damage.

[0009] Further, the rope is a steel wire rope.

[0010] By adopting the above technical solution, the staff pulls the cushion block above the segment body. While the cushion block is being pulled, the pulling force is transmitted through the pulling rope, so that the counterweight block moves upward.

[0011] Further, six groups of the cushion block, the buffer sleeve, the pulling rope, the pulley and the counterweight block are provided. Two pulleys are in a group, and both the top and the bottom of the pulling rope are in contact with the pulley.

[0012] By adopting the above technical solution, this transportation platform can transport four segment bodies at one time, increasing the transportation volume and thus improving the transportation efficiency.

[0013] Further, wheels are connected to both sides of the outer surface and both sides of the back of the transport vehicle. A cushion seat is connected to the top of the transport vehicle, and a buffer pad is connected to the top of the cushion seat. The segment body is placed on the top of the buffer pad.

[0014] By adopting the above technical solution, the staff first places a segment body on the cushion seat through a lifting device. During this period, buffering is carried out through the buffer pad to reduce damage. Then, the segment body can be transported by moving through the wheels.

[0015] Further, the lengths of the cushion block and the buffer sleeve are greater than the length of the segment body, and the segment body is in contact with the buffer sleeve.

[0016] By adopting the above technical solution, since the cushion block is longer than the segment body, the segment body is prevented from pressing on the staff's hand.

[0017] Further, a resisting plate is connected to the top of the bracket, and a bolt penetrates through the top of the resisting plate.

[0018] By adopting the above technical solution, when the transport vehicle is full of segment bodies, the staff places the resisting plate on the top of the bracket and tightens the bolt, so as to resist and limit the segment body, and avoid the phenomena of the segment body jumping and displacement.

[0019] Further, the bolt is in threaded connection with the bracket, and the resisting plate is in abutment with the segment body.

[0020] By adopting the above technical solution, the staff places the resisting plate on the top of the bracket and tightens the bolt, so as to resist and limit the segment body.

[0021] To sum up, the main beneficial effects of this utility model are as follows:

[0022] With the settings of the bracket, the abutting plate, the cushion block, the buffer sleeve, the pulling rope, the pulley and the counterweight, when the segment main body above the cushion block is removed, the cushion block and the buffer sleeve no longer receive the pressure generated by the weight of the segment main body. At this time, the cushion block and the buffer sleeve end the limit. After that, the counterweight falls due to gravity. After the counterweight falls, it pulls the cushion block through the pulling rope, and at the same time, the pulley is used to prevent the pulling rope from shifting, so as to move the cushion block and the buffer sleeve away from the top of the next segment main body; Automatically moving the cushion block away facilitates the equipment to pick up the segment main body.

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0029] The embodiments of the present utility model will be described below according to its overall structure.

[0030] Embodiment 1:

[0031] A shield segment transportation platform, as Figures 1 - 3As shown in the figure, it includes a transport vehicle 1. On both sides of the top of the transport vehicle 1, there are brackets 6 connected. Inside the brackets 6, there are pulleys 12 and a pulling rope 11 connected. The pulling rope 11 is a steel wire rope. One end of the pulling rope 11 is connected with a cushion block 9. The staff pulls the cushion block 9 above the segment main body 5. While the cushion block 9 is being pulled, the pulling force is transmitted through the pulling rope 11, so that the counterweight block 13 moves upward. Then, a segment main body 5 is placed on the cushion block 9 through a lifting device. A buffer sleeve 10 is sleeved outside the cushion block 9. The buffer sleeve 10 is made of rubber material, and the buffer is carried out through the buffer sleeve 10 to reduce damage. The lengths of the cushion block 9 and the buffer sleeve 10 are greater than the length of the segment main body 5. Since the cushion block 9 is longer than the segment main body 5, it can avoid the segment main body 5 pressing on the staff's hand. The top and bottom of the cushion block 9 and the buffer sleeve 10 are both arc-shaped to fit the shape of the segment main body 5. The other end of the pulling rope 11 is connected with a counterweight block 13. There are six groups of the cushion block 9, the buffer sleeve 10, the pulling rope 11, the pulleys 12 and the counterweight block 13. Two pulleys 12 are in a group. The top and bottom of the pulling rope 11 are both in contact with the pulleys 12. The counterweight block 13 falls by gravity. After the counterweight block 13 falls, it pulls the cushion block 9 through the pulling rope 11, and at the same time, the pulling rope 11 is prevented from deviating through the pulleys 12, so as to move the cushion block 9 and the buffer sleeve 10 away from the top of the next segment main body 5.

[0032] Refer to Figure 1 and Figure 2 , in the above embodiment, wheels 2 are connected to both sides of the outer surface and both sides of the back of the transport vehicle 1, which can move to facilitate the transportation of the segment main body 5. A cushion seat 3 is connected to the top of the transport vehicle 1. A buffer cushion 4 is connected to the top of the cushion seat 3. The segment main body 5 is placed on the top of the buffer cushion 4. A segment main body 5 is placed on the cushion seat 3. During this period, the buffer is carried out through the buffer cushion 4 to reduce damage. There are multiple segment main bodies 5. The segment main body 5 is in contact with the buffer sleeve 10, which is convenient for transporting multiple segment main bodies 5 at the same time.

[0033] Embodiment 2:

[0034] On the basis of the above Embodiment 1, in order to improve the stability during transportation, the following settings are made now.

[0035] Refer to Figure 1 , Figure 2 and Figure 4 , in the above embodiment, a resisting plate 8 is connected to the top of the bracket 6. A bolt 7 penetrates through the top of the resisting plate 8. The bolt 7 is threadedly connected with the bracket 6. The resisting plate 8 is in contact with the segment main body 5. When the transport vehicle 1 is filled with segment main bodies 5, the staff places the resisting plate 8 on the top of the bracket 6 and tightens the bolt 7, so as to resist and limit the segment main body 5 and avoid the phenomena of the segment main body 5 jumping and displacement.

[0036] The implementation principle of the present utility model is as follows: First, the staff uses a lifting device to place a segment main body 5 on the cushion base 3 first. During this process, the buffer pad 4 is used for buffering to reduce damage. Then, the staff pulls the cushion block 9 above the segment main body 5. When the cushion block 9 is pulled, the pulling force is transmitted through the pulling rope 11, so that the counterweight block 13 moves upward. Then, the staff uses the lifting device to place another segment main body 5 on the cushion block 9. At this time, since the cushion block 9 is longer than the segment main body 5, it can avoid the segment main body 5 pressing on the staff's hand. And the weight of the segment main body 5 presses the cushion block 9 to prevent the cushion block 9 from shifting. Also, the buffer sleeve 10 is used for buffering to reduce damage;

[0037] When the transport vehicle 1 is full of segment main bodies 5, the staff places the abutting plate 8 on the top of the support 6 and tightens the bolt 7 to abut and limit the segment main body 5, so as to avoid the phenomena of the segment main body 5 jumping and shifting;

[0038] When the segment main body 5 above the cushion block 9 is removed, the cushion block 9 and the buffer sleeve 10 are no longer subjected to the pressure generated by the weight of the segment main body 5. At this time, the cushion block 9 and the buffer sleeve 10 end the limit. Then, the counterweight block 13 falls by gravity. After the counterweight block 13 falls, it pulls the cushion block 9 through the pulling rope 11. At the same time, the pulley 12 is used to prevent the pulling rope 11 from shifting, so as to move the cushion block 9 and the buffer sleeve 10 away from the top of the next segment main body 5.

[0039] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
