Description

Technical Field

[0001] The utility model belongs to the technical field of construction in a vertical shaft, in particular to a telescopic supporting device for a hanging cage used for suspended construction in a vertical shaft. Background Art

[0002] Shaft construction is the general term for the excavation, walling (permanent support) and equipment installation of vertical shafts during the mining of underground deposits. Depending on the geology and hydrogeology of the rock strata through which the shaft passes, shaft construction is divided into two categories: ordinary construction and special construction for the topsoil section and bedrock section. When construction is carried out in the shaft, it is often necessary to use a hoist cage to transport concrete materials. In particular, when pouring concrete, a special concrete hoisting tank is required to transport concrete.

[0003] However, there are some problems with the existing concrete lifting tanks during use: the outlets of the existing concrete lifting tanks are usually opened and closed manually, which requires manual operation by construction workers, which is time-consuming and labor-intensive. Manual opening and closing of the outlets may cause concrete leakage due to improper operation, affecting the construction progress. Utility Model Content

[0016] Preferably, a hinged ear plate is symmetrically welded on the top surface of one side of the supporting bottom frame, and the two hinged ear plates are hinged to the bottom end of the driving rocker via a pin.

[0017] Preferably, a handle is provided at the top of the driving rocker, and a lifting ring is symmetrically welded at the top of the concrete lifting tank.

[0018] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0019] The telescopic support device for the suspended construction cage in the shaft can effectively prevent concrete leakage in a non-working state by setting a semi-automatic opening and closing outlet component, reducing safety hazards during construction. The design of the support frame component ensures the stability of the construction cage assembly in the shaft, further enhancing the safety of the construction process. The cylinder controls the driving rocker to achieve automatic opening and closing of the outlet, simplifying the operation process and improving construction efficiency. In the event of a cylinder failure or power outage, the opening and closing of the outlet can also be controlled by manually operating the driving rocker, increasing the flexibility and reliability of the system.

[0020] The automatic opening and closing of the outlet reduces the number of manual operations of workers and the intensity of physical labor. The opening and closing actions are realized through mechanical linkage, which reduces the burden on workers and makes the unloading of concrete easier and faster. The semi-automatic opening and closing components of the outlet adopt a unique mechanical linkage design. The cylinder controls the driving rocker to realize the opening and closing of the first opening and closing plugging receiving plate and the second opening and closing plugging receiving plate. Compared with traditional manual or fully automated solutions, this has higher reliability and lower maintenance costs. The meshing tooth design of the first opening and closing plugging receiving plate and the second opening and closing plugging receiving plate ensures the tightness of the outlet in the closed state and avoids the problem of concrete leakage.

[0044] How it works

[0045] The telescopic support device for the cage used for suspended construction in the vertical shaft, the first opening and closing sealing receiving plate 8 and the second opening and closing sealing receiving plate 15 are used to control the opening and closing of the bottom outlet of the concrete lifting tank 2, the hinged pull rod 11 cooperates with the fixed connecting rod 10 to pull the first opening and closing sealing receiving plate 8, and the driving rocker 7 is connected to the fixed connecting rod 10. Through the push-pull action of the cylinder part 19, the driving rocker 7 can swing up and down, thereby controlling the opening and closing of the first opening and closing sealing receiving plate 8 and the second opening and closing sealing receiving plate 15. The cylinder part 19 pushes the driving rocker 7 through the extension and retraction of the piston rod to realize the opening and closing action.

[0046] The first opening and closing sealing receiving plate 8 and the second opening and closing sealing receiving plate 15 are engaged with the meshing teeth 14 and close the bottom outlet of the concrete lifting tank 2. The piston rod of the cylinder member 19 extends to push the driving rocker 7 to move upward. The driving rocker 7 pulls the first opening and closing sealing receiving plate 8 backward through the fixed connecting rod 10 and the hinged pull rod 11. Due to the action of the meshing teeth 14, the first opening and closing sealing receiving plate 8 will be separated from the meshing teeth 14 of the second opening and closing sealing receiving plate 15 when retreating. The two are separated back to back, opening the bottom outlet of the concrete lifting tank 2, and the concrete can be discharged.

[0047] The piston rod of the cylinder 19 retracts, driving the rocker arm 7 to move downward, and the driving rocker arm 7 releases the pulling force on the first opening and closing sealing receiving plate 8 through the fixed connecting rod 10 and the hinged pull rod 11. The first opening and closing sealing receiving plate 8 and the second opening and closing sealing receiving plate 15 are reset under the action of their own gravity or spring force, and the meshing teeth 14 re-engage, thereby closing the bottom outlet of the concrete lifting tank 2.

[0048] The U-shaped fixing plate 18 is used to install the cylinder component 19 and provide support. The fixing sleeve 22 is welded to the free end of the piston rod of the cylinder component 19 and is used to connect with the sleeve component 20. The sleeve component 20 is sleeved on the peripheral side of the driving rocker 7 and is connected to the fixing sleeve 22 by inserting the inner rod 24 and fixed by the locking bolt 25 to transmit the push and pull force of the cylinder component 19. The extension plate 21 is welded on the peripheral side of the sleeve component 20 to increase the structural strength. The positioning cross bar 23 is welded to the inner wall of the extension plate 21 and passes through the U-shaped fixing plate 18 to ensure the stable sliding of the sleeve component 20 on the driving rocker 7.
