[0002] Pipe jacking is a trenchless construction technology that is widely used in the laying of underground pipelines, cables and other facilities, especially when it is necessary to cross roads, railways, rivers, buildings and other underground obstacles. Its core feature is that it can complete the installation of underground pipelines without excavation or minimize surface excavation, thereby minimizing interference with ground transportation, the environment and existing infrastructure.

[0003] A large amount of slag will be generated during the pipe jacking construction process. The slag discharge process of the existing technology is: loading the slag into the slag bucket of the transport vehicle, then transporting the slag to the pipe jacking shaft by the transport vehicle, and then lifting the slag bucket to the pipe jacking shaft by the hoisting equipment, and finally unloading the slag and loading it onto the vehicle; the current slag bucket mainly adopts inclined discharging and bottom loose-leaf opening and closing discharging methods for discharging, but the inclined discharging not only has a slow unloading speed but also easily leaves waste materials in the bucket, which will affect the loading capacity and discharging efficiency of the slag bucket for a long time, and it is often necessary to manpower to clean up the residual waste materials, which is time-consuming and labor-intensive, and has low work efficiency; the bottom loose-leaf opening and closing discharging requires manual opening and closing of the leaves, which is not only time-consuming and labor-intensive, but may also cause safety hazards due to improper operation. Summary of the invention

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A kind of excavation bucket for pipe jacking shaft comprises a box body which is hollow inside and opened at the upper and lower ends, a baffle plate hinged on the bottom of the box body and used for covering the opening at the bottom of the box body, a plurality of main lifting ears arranged on the outer side wall of the upper end of the box body, a transmission mechanism which is respectively arranged on the front and rear outer side walls of the box body and connected to the baffle plate, and an auxiliary lifting ear arranged on the transmission mechanism. When the auxiliary lifting ear is subjected to an upward force, the baffle plate is opened under the action of the transmission mechanism, and when the auxiliary lifting ear plate is not subjected to force, the baffle plate is closed under the action of the transmission mechanism.

[0007] Preferably, the transmission mechanism includes: a drum assembly fixed on the outer wall of the box body, a wire rope wound on the drum assembly, a screw rod rotatably arranged on the outer wall of the box body at both ends, a moving block threadedly sleeved on the screw rod, a connecting rod hinged to the moving block at one end and to the side wall of the baffle at the other end, and a transmission assembly arranged between the drum assembly and the screw rod, and the auxiliary lifting ear is connected to the wire rope.

[0008] Preferably, the reel assembly includes: two mounting plates symmetrically arranged on the outer side walls of the box body, fixed shafts whose two ends are fixedly connected to the two mounting plates, a reel body which is rotatably sleeved on the outside of the fixed shaft and is hollow inside, and a coil spring whose inner end is fixed to the fixed shaft and whose outer end is fixed to the inner wall of the reel body, and one end of the wire rope is fixed to and wound around the reel body.

[0009] Preferably, the transmission assembly comprises: a first gear fixedly sleeved on the outside of the reel body, and a second gear fixedly sleeved on the lead screw and meshing with the first gear.

[0010] Preferably, there are two baffles, which are symmetrically arranged at the bottom of the box, and one end of the two baffles is hinged to the bottom of the box away from each other. The screw rod is transversely arranged on the outer side wall of the box, and the screw rod is a bidirectional screw rod, and movable blocks are respectively threadedly sleeved at both ends of the screw rod.

In the utility model, when the auxiliary lifting ear is subjected to an upward pulling force, the wire rope is pulled and then drives the drum body to rotate, so that the coil spring is stretched, and through the meshing of the first gear and the second gear, the screw rod also starts to rotate, thereby driving the moving block to move on the screw rod, and the moving block pushes the baffle to open through the connecting rod, and the slag flows out. When the auxiliary lifting ear is not subjected to force, the coil spring releases the torque, so that the drum body returns to the initial position, and at the same time drives the screw rod to rotate, so that the moving block moves upward, and the baffle is closed through the connecting rod. The coordinated use of the drum assembly, the screw rod, the moving block, the connecting rod and the transmission assembly realizes the automatic opening and closing of the baffle, thereby improving the automation and safety of the excavated slag bucket;

[0017] 3. The utility model can effectively protect the internal space of the excavated slag bucket by arranging two switch covers on the top of the box body, prevent the lifted slag from spilling, avoid damage or pollution to the underground construction equipment, tools or materials of the jacking well, and avoid harm to the construction personnel.

When the auxiliary lifting ear 4 is subjected to an upward force, the baffle 2 is opened under the action of the transmission mechanism, and when the auxiliary lifting ear 4 is not subjected to a force, the baffle 2 is closed under the action of the transmission mechanism.

[0031] In actual use, the excavated slag bucket can be transported to the jacking well by the hoisting equipment, and then the auxiliary lifting lug 4 is forced upward by the hoisting equipment to open the baffle 2 for discharge; after the discharge is completed, the baffle 2 will automatically close under the action of the transmission mechanism by simply stopping the force applied to the auxiliary lifting lug 4. The whole process does not require manual intervention, which is convenient and safe.

[0032] The transmission mechanism includes: a drum assembly 5 fixed on the outer wall of the box body 1, a wire rope 6 wound on the drum assembly 5, a screw rod 7 rotatably arranged on the outer wall of the box body 1 at both ends, a moving block 8 threadedly sleeved on the screw rod 7, a connecting rod 9 hinged to the moving block 8 at one end and hinged to the side wall of the baffle 2 at the other end, and a transmission assembly 10 arranged between the drum assembly 5 and the screw rod 7, and the auxiliary lifting ear 4 is connected to the wire rope 6.
