Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel construction technology, and in particular to a water tank gantry crane system. Background Technology
[0002] During tunnel construction, drainage is often necessary. Therefore, water collection chambers are installed inside the tunnel to store groundwater, and water pumps and corresponding pipeline systems are placed next to these chambers for active drainage. For tunnels with severe water inrush problems, such as some located in high-altitude areas, continuous 24-hour drainage is required, placing a heavy burden on the water pumps. Therefore, a large number of water pumps need to be installed along the tunnel's longitudinal direction, and these pumps require frequent maintenance and repair. Correspondingly, multiple fixed lifting devices need to be spaced along the tunnel's longitudinal direction to lift and relay the water pumps. However, this approach has the following problems:
[0003] (1) The separate installation of water pumps and their auxiliary equipment (such as electrical cabinets), fixed lifting equipment and water collection tanks will occupy a large amount of space inside the tunnel, resulting in low space utilization inside the tunnel.
[0004] (2) Multiple fixed lifting equipment need to be purchased, and relay transportation is required when transporting water pumps. The equipment cost and maintenance cost are high, and the maintenance efficiency is low. Utility Model Content
[0005] The purpose of this utility model is to overcome the technical problems of existing technology, which involves setting up water collection tanks, water pumps and fixed lifting equipment along the longitudinal direction of the tunnel, resulting in low utilization of tunnel interior space, high equipment and maintenance costs and low maintenance efficiency, and to provide a water tank gantry crane system.
[0006] In a first aspect, this utility model provides a water tank gantry crane system, including a water collection tank located at the bottom of a tunnel, and further including: an equipment platform located above the water collection tank for housing a water pump; a gantry crane device located above the equipment platform, the gantry crane device including a longitudinal beam, a transverse beam, and a lifting trolley; the longitudinal beam is arranged along the longitudinal direction of the tunnel, the transverse beam is arranged along the transverse direction of the tunnel, the transverse beam is slidably connected to the longitudinal beam, and the transverse beam is movable along the longitudinal beam; the lifting trolley is slidably connected to the transverse beam, and the lifting trolley is movable along the transverse beam; the lifting trolley is equipped with a winch and a hook.
[0007] This solution involves stacking the water collection tank, equipment platform, and gantry crane sequentially from bottom to top within the tunnel. The water collection tank stores water, the equipment platform houses the water pumps, and the gantry crane lifts and moves the pumps. This design effectively utilizes the tunnel's vertical space, significantly reducing the space occupied by the water collection tank, pumps, and lifting equipment along the tunnel's longitudinal direction, thus improving space utilization. Furthermore, compared to existing technologies that use multiple fixed lifting devices for relay transport of pumps, this solution's gantry crane includes a horizontal beam that moves along the longitudinal beam (tunnel longitudinal direction) and a lifting trolley that moves along the horizontal beam (tunnel transverse direction). This allows a single gantry crane to cover the entire area below it, enabling rapid lifting and transport of pumps from the equipment platform. This not only reduces the equipment and maintenance costs of the pump lifting equipment but also improves the pump transport efficiency.
[0008] Preferably, the equipment platform is also provided with an observation port, which is connected to the water collection tank.
[0009] This solution allows staff to easily observe the water storage status of the lower water collection tank from the equipment platform, enabling them to adjust the drainage plan accordingly.
[0010] Preferably, at least one ladder is provided at the edge of the observation port, with one end of the ladder leading to the equipment platform and the other end leading to the water collection tank.
[0011] This solution allows staff to easily descend from the equipment platform into the water collection tank for inspection and maintenance, and then smoothly return to the equipment platform after completing the inspection and maintenance work.
[0012] Preferably, a guardrail is provided around the circumference of the observation port.
[0013] This solution prevents staff from accidentally falling into the water collection tank through the observation port.
[0014] Preferably, the longitudinal beam is connected to the top of the tunnel.
[0015] This solution connects the longitudinal beam to the tunnel for two reasons. First, the longitudinal beam needs to be located above the equipment platform, so connecting it directly to the top of the longitudinal beam is more convenient and direct. Second, this solution allows the tunnel structure to bear the load on the longitudinal beam. Compared with other connection methods, such as supporting the longitudinal beam on the equipment platform, this solution can reduce the strength and stiffness requirements of the equipment platform, thereby simplifying the design and construction of the equipment platform.
[0016] Preferably, there are at least two longitudinal beams, which are spaced apart along the width of the tunnel.
[0017] This solution can improve the load-bearing capacity of the gantry crane and enhance the limiting effect of the longitudinal beams on the transverse beams, thereby ensuring the stability of the transverse beams when they move along the longitudinal beams.
[0018] Preferably, a connecting beam is also provided between two adjacent longitudinal beams. The length of the connecting beam is set along the transverse direction of the tunnel, and the two ends of the connecting beam are respectively connected to the longitudinal beams on the corresponding sides.
[0019] This solution can improve the structural safety of the gantry crane.
[0020] Preferably, there are at least two crossbeams, which are spaced apart along the longitudinal direction of the tunnel; the trolley is slidably connected between two adjacent crossbeams.
[0021] This solution can improve the load-bearing capacity of the gantry crane and enhance the limiting effect of the crossbeam on the trolley, thereby ensuring the stability of the trolley when it moves along the crossbeam.
[0022] Preferably, at least one end of the longitudinal beam extends beyond the equipment platform along the longitudinal direction of the tunnel.
[0023] This solution allows the gantry crane to easily move the water pump from the equipment platform to the outside of the equipment platform, or vice versa.
[0024] Preferably, the equipment platform includes a steel panel and an orthogonal frame. The orthogonal frame is connected to the sidewall of the tunnel and includes several orthogonally arranged steel sections. The steel panel is connected to the top surface of the orthogonal frame.
[0025] This solution ensures that the equipment platform has sufficient strength and rigidity, while also providing a flat surface above the platform for placing equipment and allowing personnel to move around.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0027] This utility model provides a water tank gantry crane system. By stacking the water tank, equipment platform, and gantry crane device sequentially from bottom to top inside the tunnel, it can significantly reduce the space occupied by the water tank, water pump, and their lifting equipment along the longitudinal direction of the tunnel by utilizing the vertical space inside the tunnel, thereby improving the space utilization rate inside the tunnel. On the other hand, it can use one gantry crane device to cover all areas below it, thereby quickly lifting and transporting the water pump on the equipment platform. This not only reduces the equipment cost and operation and maintenance cost of the water pump lifting equipment, but also improves the transportation efficiency of the water pump.
