[0038] 1. Transfer device; 2. Suspended basket device. Detailed Implementation

[0039] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0040] A semi-automatic excavation lifting device for tunneling projects includes a suspended basket device 2, which is connected to a transfer device 1. This invention discloses a semi-automatic excavation lifting device for tunneling projects. The lifting device disclosed in this invention, through the cooperation of the suspended basket device 2 and the transfer device 1, can realize the transfer of soil from the inside to the outside of the working well, thereby realizing the excavation operation in semi-automatic tunneling projects.

[0041] Specifically, the lifting equipment disclosed in this invention is mainly used for the transportation of excavated soil in underground excavation projects. Specifically, the transfer device 1 disclosed in this invention includes a support frame 1-1, which provides excellent bottom support, effectively elevating the entire lifting equipment. Furthermore, the support frame 1-1 is equipped with a hooking mechanism, facilitating the subsequent hooking of the suspended basket 21. Specifically, the hooking mechanism includes reverse saw teeth 12 arranged in a ring on the support frame 1-1. The reverse saw teeth 12 are connected to a drive mechanism. Through the drive mechanism, the reciprocating motion of the reverse saw teeth 12 can be achieved, enabling the subsequent transfer of the suspended basket 21.

[0042] In addition, the transfer device 1 described in this invention also includes a transfer mechanism 11. The transfer mechanism 11 includes a corrugated conveyor strip mounted on a support frame 1-1. The corrugated conveyor strip is connected to a rotating mechanism 13. The corrugated conveyor strip includes a strip body 111, and the strip body 111 is provided with a plurality of limiting corrugations 112. The transfer mechanism 11 is also used for hoisting the suspended basket 21. The corrugated conveyor strip is equivalent to a conveyor belt mechanism. The limiting corrugations 112 on the corrugated conveyor strip provide good lateral limiting, which helps to ensure the stability of the suspended basket 21 on the corrugated conveyor strip.

[0043] Meanwhile, the suspended basket device 2 in this invention includes a suspended basket box 21; the suspended basket box 21 is provided with box ribs; the suspended basket box 21 facilitates the loading of earthwork and slag during subsequent use and facilitates subsequent transfer operations. At the same time, the box ribs on the suspended basket box 21 play a good limiting role and facilitate the connection between the suspended basket box 21 and the transfer mechanism 11 and the hanging mechanism.

[0044] Furthermore, in this invention, the reverse sawtooth 12 includes a rack 121, on which teeth 122 are provided. The vertical cross-section of the teeth 122 is a right-angled triangle. Through this arrangement, the rack 121 is a strip-shaped band, which facilitates subsequent rotation under the drive mechanism. In addition, the teeth 122 on the rack 121 play a good limiting role, which facilitates cooperation with the box ribs on the suspended basket box 21, making it convenient for the suspended basket box 21 to be hooked on the reverse sawtooth 12. In actual implementation, it is required that the teeth be perpendicular to the side of the rack and fit against the side back rib. This design, because the side is relatively high, can better ensure the stability of the suspended basket box hooked on the reverse sawtooth 12.

[0045] In addition, the box body ribs in this invention include side back ribs 25 provided on the suspended basket box body 21, and a box body bottom rib 24 is provided below the suspended basket box body 21; in this invention, the side back ribs 25 facilitate the hanging of the suspended basket box body 21 on the reverse saw teeth 12, and the box body bottom rib 24 plays a good bottom limiting role, which facilitates the cooperation between the suspended basket box body 21 and the limiting rib 112, and ensures the stability of the suspended basket box body 21 on the ribbed conveyor strip.

[0046] In addition, in actual arrangement, a rotating block 3 is provided at the end of the tooth 122, and the end of the tooth is provided with a mounting groove 1221; the rotating block 3 is inserted into the mounting groove 1221 through a rotating horizontal shaft 32, and a return spring 33 is provided on the rotating horizontal shaft 32. In use, the rotating block 3 is arranged laterally under the action of the return spring 33; it plays a good limiting role and increases the difficulty of the suspended basket body disengaging from the reverse sawtooth 12; at the same time, in this invention, the rotating block 3 is connected to the tooth through the rotating horizontal shaft 32. The setting of the rotating horizontal shaft 32 plays a good folding role, which facilitates the folding of the rotating block 3 during use and avoids the rotating block 3 being placed horizontally for a long time, thus affecting the movement of the suspended basket body.

[0047] In addition, a reset mechanism is provided between the rotating block 3 and the tooth 122 in this invention. The reset mechanism includes a return spring 33, which is sleeved on the rotating horizontal shaft 32. One end of the return spring 33 is in contact with the inner wall of the mounting groove 1221 on the tooth, and the other end is in contact with the rotating block 3. The reset mechanism facilitates the rotating block 3 to be in a horizontal state under normal use, which plays a good limiting role and increases the chance of the basket body disengaging from the reverse sawtooth. The function of the return spring 33 is similar to that of the seats in a traditional tiered classroom. In this invention, the function of the return spring 33 is to ensure that the rotating block 3 has the ability to be in a horizontal position for a long time. Therefore, the return spring 33 applies a pushing force to the rotating block 3 to ensure that the rotating block 3 has an external force that keeps it in a horizontal state.

[0048] Furthermore, in this invention, the rotating block 3 is provided with a positioning groove 31 at its end; the rotating horizontal shaft 32 passes through the rotating block 3, and the return spring 33 is arranged in the positioning groove 31; one end of the return spring 33 is in contact with the inner wall of the mounting groove 1221 on the tooth 122, and the other end is in contact with the bottom surface of the positioning groove 31 of the rotating block 3; in this invention, the positioning groove 31 serves as a good storage and avoidance mechanism. Storage facilitates the insertion and storage of the rotating horizontal shaft 32, and also facilitates the arrangement and storage of the return spring 33. Avoidance mainly avoids the movement interference between the rotating block 3 and the tooth 122 when rotating; it also serves as a positioning mechanism, because the return spring 33 is placed inside the positioning groove 31, and generally the end of the return spring 33 presses against the side wall of the positioning groove 31, thereby preventing the return spring 33 from moving around in the positioning groove 31.

[0049] Furthermore, in this invention, the end face of the rotating block 3 is in contact with the tooth 122. This contact effectively limits the position of the rotating block 3, preventing it from swinging downwards or shifting under the action of the return spring 33. It also provides good calibration, ensuring the accuracy of subsequent insertion of the rotating block 3. Additionally, in this invention, the rotating block 3 has a rounded transition surface 34 near the tooth 122. This rounded transition surface 34 is located on one side of the rotating block 3's rotation direction. The purpose of designing the rounded transition surface 34 is to ensure the rotation of the rotating block 3 and facilitate its folding under external force.

[0050] Furthermore, in this invention, the suspended platform body includes a base plate, on which a connecting side plate is provided. The connecting side plate includes a first side plate 2-1, a second side plate 2-2, a third side plate 2-3, and a fourth side plate 2-4. The base plate and the connecting side plate form a box structure with a hollow upper end. Through the above design, this invention forms a box structure with an opening at the upper end, facilitating the filling of excavated soil to be transported during subsequent use. In addition, in this invention, the first side plate 2-1 and the third side plate 2-3 are arranged opposite to each other; both the first side plate 2-1 and the third side plate 2-3 are provided with... The device has a side back rib 25; the height of the first side plate is less than the height of the third side plate 2-3; at the same time, the heights of the second side plate 2-2 and the fourth side plate are not greater than the height of the third side plate, the second side plate 2-2 and the fourth side plate have the same height, and both are greater than the height of the first side plate 2-1; through the above design, the invention ensures that even if the suspended basket body tends to be horizontal, the soil and slag inside the suspended basket body will not detach from the suspended basket body; at the same time, the third side plate in the invention is provided with a reserved hole 22 for loading; the invention facilitates subsequent soil removal operations in conjunction with the pipe jacking machine by setting the reserved hole 22.

[0051] Furthermore, in this invention, the suspended basket body is provided with a cover plate 23, which is connected to the third side plate by a hinge; the cover plate 23 covers the reserved hole 22; the cover plate 23 plays a good blocking role, preventing soil from flowing out of the suspended basket body from the reserved hole 22.

[0052] Furthermore, in this invention, the support frame 1-1 includes a single frame 1-11, and the single frame 1-11 includes two bottom supports 1-12; the two bottom supports 1-12 are arranged opposite to each other and are distributed on both sides of the corrugated conveyor strip; each bottom support 1-12 is provided with an upper support 1-13; the reverse sawtooth 12 is arranged on the upper support 1-13; the present invention, through the spaced distribution of multiple single frames 1-11, facilitates the subsequent adjustment of the spacing between adjacent single frames 1-11 as needed. In actual use, the relative arrangement position of the support frames 1-1 can be changed, making the present invention applicable to working wells of different depths, thereby improving the applicability of the present invention.

[0053] Furthermore, in this invention, adjacent single-unit frames 1-11 are connected by an adjustment mechanism, which includes a hydraulic telescopic rod 1-14 disposed between adjacent single-unit frames 1-11. By setting the hydraulic telescopic rod 1-14, this invention can not only connect adjacent single-unit frames 1-11, but also change the relative interval between adjacent single-unit frames 1-11 as needed, thereby better improving the applicability of this invention.

[0054] Furthermore, in this invention, the rotating mechanism 13 includes a rotating roller 131, which is connected to the corrugated conveyor belt via a meshing part. The meshing part includes external teeth 1311 disposed on the rotating roller 131 and internal teeth 11-11 on the inner side of the corrugated conveyor belt. The rotating roller 131 meshes with the internal teeth 11-11 of the corrugated conveyor belt via the external teeth 1311. This invention facilitates the connection between the rotating mechanism 13 and the corrugated conveyor belt through the meshing part.

[0055] Furthermore, the chain body 111 of the present invention includes a plurality of chain blocks connected in sequence; each chain block is connected by a pin, and each chain block includes an inner chain block 1112 and an outer chain block 1111, the inner chain block 1112 and the outer chain block 1111 being connected by a pin; the inner chain block 1112 includes two opposing inner chain plates, the outer chain block 1111 includes two opposing outer chain plates, and the pin 1113 is provided with a roller sleeve; in fact, the chain body 111 described above is just like the structure of a traditional bicycle chain, the main difference being the size; in actual use, by selecting different numbers of chain blocks to form chain bodies 111 of different lengths, the applicability of the present invention is greatly improved.

[0056] A method for using a semi-automatic hoisting device for excavation in underground tunneling projects, the method comprising the following steps:

[0057] Step 1: Arrange the hoisting equipment inside the working shaft according to its depth;

[0058] Step 2: Install the suspended platform device 2 onto the transfer device 1;

[0059] Step 3: After completing Step 2, fill the suspended basket 21 with the soil to be transported;

[0060] Step 4: After step 3 is completed, start the transfer device 1; so that it moves the basket box 21, thereby realizing the transfer of soil from the inside of the working well to the outside.

[0061] specific;

[0062] This invention discloses a semi-automatic hoisting device for excavation in tunneling projects. The device is suitable for pipe jacking or tunneling projects. However, such projects generally require the construction of a rectangular working well, which is typically 5-11m deep. Therefore, the inclined part of the device is needed to realize the semi-automatic vertical transportation of the excavation box.

[0063] As shown in the attached diagram, after installation, place it in the designated location on site, adjust each rotating mechanism 13 to keep them in the same direction and at the same speed, and after ensuring that the whole device can operate, turn it off.

[0064] In subsequent use, as the pipe jacking construction machinery advances, the excavated soil enters the suspended basket box 21 through the reserved hole 22. After the soil fills the entire suspended basket box 21, the transfer device 1 is started. Through the cooperation of the reverse saw teeth 12, the limiting ribs 112 and the box body ribs, the suspended basket box 21 can be hooked onto the transfer device 1. Subsequently, the transfer device 1 operates, driving the suspended basket box 21 to move and transport the soil to the open ground outside the working well. Then, the soil is manually disposed of.

[0065] After the excavated soil is disposed of, the basket body 21 can be returned to the jacking pipe at the bottom of the foundation pit by reversing the switch and running the transfer device 1 in the opposite direction; this can be repeated.

[0066] Of course, after the excavated soil is disposed of, the basket box 21 can be transported back without using the transfer device 1. An additional hook or a crane can be used to lower the basket box 21. The purpose of this operation is to reduce the back transportation of the transfer device 1 and improve the soil transportation efficiency of the lifting equipment.

[0067] In addition, as the pipe jacking continues, the longitudinal length of the entire device can be adjusted by increasing the number of chain blocks and cooperating with hydraulic telescopic rods 1-14 during the jacking process.

[0068] Meanwhile, the present invention mainly comprises two parts: a suspended basket device 2 and a transfer device 1.

[0069] The transfer device 1 is the main part of the invention; in this invention, the transfer device 1 mainly includes a transfer mechanism 11 and a hooking mechanism. The hooking mechanism includes a reverse sawtooth 12, which can cooperate with the side back rib 25 in the direction of rotation of the device to realize the hooking of the suspended basket body 21; at the same time, a ribbed conveyor strip is provided on the support frame 1-1, which will subsequently be rotated to transport the corresponding suspended basket body 21 to a high place, playing a good transmission and transfer role.

[0070] In addition, the corrugated conveyor bar of the present invention is connected to a rotating mechanism 13. The rotating roller 131 of the rotating mechanism 13 is connected to a drive motor. The drive motor drives the rotating roller 131 to rotate. The rotating roller 131 and the corrugated conveyor bar cooperate with each other, so that the corrugated conveyor bar can rotate with the rotating roller 131.

[0071] Meanwhile, in this invention, the transfer device 1 also includes a support frame 1-1, which includes a single frame 1-11. Adjacent single frames 1-11 are spaced apart. Each single frame 1-11 includes two bottom supports 1-12. The two bottom bases are spaced apart. The bottom supports 1-12 provide good bottom support. At the same time, an upper support 1-13 is provided on the bottom support 1-12. The upper supports 1-13 are also symmetrically distributed. The setting of the upper supports 1-13 also provides good support and placement, which facilitates the arrangement of the reverse saw teeth 12.

[0072] Meanwhile, in this invention, the reverse serrations 12 are also arranged in a ring.

[0073] In addition, the reverse sawtooth 12 is also provided with a drive unit at both ends. The drive unit may also involve a rotating mechanism 13 similar to the above-mentioned; the reverse sawtooth 12 can also be driven by the meshing part; the main purpose is to realize the rotation of the reverse sawtooth 12.

[0074] Meanwhile, in this invention, an adjustment mechanism is provided between adjacent single frames 1-11. The adjustment mechanism is mainly a hydraulic telescopic rod 1-14, whose length can be varied to adjust the distance between adjacent single frames 1-11; thereby adjusting the working area of ​​the lifting equipment.

[0075] Meanwhile, the suspended basket box 21 of the present invention is a steel box structure, mainly used for holding earthwork; the suspended basket box 21 is provided with a reserved hole 22, which is used to reserve the position of the soil outlet of the pipe jacking machine, so that the soil during the mechanical jacking process can be directly transported into the box; at the same time, in order to prevent soil leakage from the reserved hole 22, a reserved hole 22 cover plate 23 is provided at the edge of the reserved hole 22.

[0076] The specific installation method for this device is as follows:

[0077] First, based on the dimensions of the pipe jacking working shaft, determine the quantity and position of the rotating mechanism 13 and the single frame 1-11 in the rotating device. After determining the position and quantity, fix the support frame 1-1, and then install the hydraulic telescopic rod 1-14 in the adjusting mechanism. The hydraulic telescopic rod 1-14 can be automatically adjusted in length according to the on-site construction conditions. Next, install the corrugated conveyor bar, which is a chain-type connection and can be increased or decreased according to the construction length. Finally, install the transfer device 1 in place, and the installation is complete.

[0078] Then, the suspended platform device 2 is installed, and the suspended platform device 2 is connected to the transfer device 1 through the box body ribs.

[0079] in:

[0080] In this invention, the rotating mechanism 13 mainly includes a rotating roller 131 disposed on the bottom support 1-12. The rotating roller 131 is provided with external teeth 1311, which facilitates subsequent cooperation with the corrugated conveyor strip.

[0081] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
