Description

Technical Field

[0001] This utility model relates to the field of shaft construction technology, and in particular to a shaft excavation hoisting frame. Background Technology

[0002] Vertical shafts, as an important underground engineering structure, are widely used in various fields due to their multifunctionality. In addition to basic functions such as drainage and ventilation, vertical shafts also play a crucial role in transporting goods and personnel. During tunnel construction or operation, vertical shafts act as "natural chimneys," efficiently expelling smoke and harmful gases generated during construction or improving air circulation within the tunnel.

[0003] Currently, when excavating a shaft, construction workers enter the shaft via an internal ladder, which is inconvenient for transporting excavation tools into the shaft, hindering the excavation work. Therefore, a shaft excavation hoisting rig is needed to meet the requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting frame for vertical shaft excavation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting derrick for vertical shaft excavation, comprising a derrick, a steel structure composite truss arranged below the derrick, supports installed on the steel structure composite truss, the bottom end of the derrick installed on the supports, inclined support columns installed on the sides of the derrick, a top support column installed on the top of the derrick, a hoisting box arranged inside the derrick, a transport platform installed on the steel structure composite truss, and a top steel plate arranged above the derrick.

[0006] Preferably, a hanging column is installed on the top support column, a sheave is installed at the bottom of the hanging column, a sling is movably installed inside the sheave, a connecting seat is installed on the hanging box, and the tail end of the sling is installed on the connecting seat.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] like Figure 1-4 As shown, this embodiment provides a hoisting derrick for vertical shaft excavation, including a derrick 1, a steel structure composite truss 2 installed below the derrick 1, supports 3 installed on the steel structure composite truss 2, the bottom end of the derrick 1 installed on the supports 3, inclined support columns 4 installed on the sides of the derrick 1, a top support column 5 installed on the top of the derrick 1, a hoisting box 6 installed inside the derrick 1, a transport platform 7 installed on the steel structure composite truss 2, and a top steel plate 8 installed above the derrick 1. The steel structure composite truss 2 is fixed near the shaft opening for convenient tool transport. The four pillars of the derrick 1 are welded to the supports 3, and the top support column 5 is welded to the derrick 1 to improve the shear strength and load-bearing capacity of the derrick 1. The top steel plate 8 is fixed to the top surface of the vertical shaft construction chamber to prevent falling rocks from causing safety accidents. When transportation is needed, construction workers transport the tools to the transportation platform 7 and place the excavation tools in the hoisting box 6. The hoisting box 6 is lowered and the tools are transported into the shaft. The construction workers working underground can then take out the construction tools from the hoisting box 6. The operation is relatively convenient and facilitates the construction work of the personnel inside the shaft.

[0023] Furthermore, the enclosure lowers the hoisting box 6 into the shaft. A hoisting column 9 is installed on the top support column 5, and a sheave 10 is installed at the bottom of the hoisting column 9. A sling 11 is movable inside the sheave 10. A connecting seat 12 is installed on the hoisting box 6, and the tail end of the sling 11 is installed on the connecting seat 12. A base 23 is installed on the outside of the derrick 1, and a winch 24 is installed on the cover 13. A guide wheel 25 is installed on the top support column 5, and the starting end of the connecting seat 12 is set on the guide wheel 25. When the winch 24 is started, under the guidance of the sheave 10 and the guide wheel 25, the winch 24 unwinds and lowers the hoisting box 6 through the sling 11, transporting the tools into the shaft. The operation is relatively convenient and facilitates the construction work of personnel inside the shaft.

[0024] Furthermore, to facilitate opening the cover 13, a cover 13 is provided at the opening of the hoisting box 6. Hinges 14 are installed on the hoisting box 6 and the cover 13, and a handle 15 is installed on the cover 13. By pulling the handle 15, the cover 13 is opened under the action of the hinge 14, and the construction personnel place the excavation tools inside the hoisting box 6.

[0025] Furthermore, to facilitate locking of the cover 13, a locking rod 16 is engaged inside the handle 15, a support block 19 is installed on the side of the hanging box 6, a rotating shaft 17 is installed on the locking rod 16, and a torsion spring 18 is installed on the locking rod 16 and the support block 19. The rotating shaft 17 is rotatably installed inside the support block 19. Rotating the locking rod 16 causes the rotating shaft 17 to rotate inside the support block 19, which can cause the locking rod 16 to be displaced and separated from the handle 15, thus releasing the lock on the cover 13. Under the action of the torsion spring 18, the locking rod 16 can rotate back to its original position and engage inside the handle 15, at which point the cover 13 can be locked.

[0026] Furthermore, to secure the steel structure composite truss 2 and the inclined support column 4, side support columns 20 are installed on the derrick 1, a first fixing seat 21 is installed at the bottom of the steel structure composite truss 2, and a second fixing seat 22 is installed at the bottom of the inclined support column 4; the steel structure composite truss 2 and the inclined support column 4 can be fixed to the ground by the first fixing seat 21 and the second fixing seat 22 respectively.

[0027] Working principle: In use, the steel structure composite truss 2 is fixed near the shaft opening via the first fixing seat 21 for convenient tool transportation. The four supports of the shaft frame 1 are then welded to the support 3. The top support column 5 and side support columns 20 are then welded onto the shaft frame 1 in sequence. These columns enhance the shear strength and load-bearing capacity of the shaft frame 1. The top steel plate 8 is then fixed to the top surface of the shaft construction chamber to prevent falling rocks from causing accidents. When tools need to be transported, workers move them to the transport platform 7. Rotating the locking rod 16 causes the rotating shaft 17 to rotate within the support block 19, displacing the locking rod 16 from the handle 15. Pulling handle 15 opens the cover 13 under the action of hinge 14. Workers then place the excavation tools inside the hoisting box 6 and close the cover 13. The torsion spring 18 causes the locking rod 16 to rotate and reset, locking into handle 15, thus locking the cover 13. Next, start the winch 24. Guided by the sheave 10 and guide wheel 25, the winch 24 unwinds, lowering the hoisting box 6 via the sling 11 and transporting the tools into the shaft. The guide wheel 25 facilitates operation and allows workers inside the shaft to work more easily.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
