Description

Technical Field

[0001] The utility model relates to the technical field of tunnel rescue equipment, in particular to a rescue machine. Background Art

[0002] There are many inconveniences in the current methods for rescuing trapped construction workers. For example, ordinary rescue relies on manual excavation or the use of large machinery such as excavators. Excavation by manual labor and such machinery takes a long time, and excavation by large machinery requires a good working environment. In many cases, there are too many restrictions and rescue operations cannot be carried out, resulting in threats to the lives of trapped workers. In addition, there is a lack of temporary support after the rescue channel is excavated, which makes it easy for secondary collapse to occur, and it is impossible to meet effective and rapid rescue measures.

[0003] Instead of the traditional method of manual excavation and rescue, the current development of pipe jacking rescue excavation is a rescue method that uses the excavation equipment body to push a tool steel pipe of a certain diameter through the slag when a tunnel collapses, and manually removes the slag in the pipe to form an escape passage. For example, the patent "A Tunnel Rescue Pipe Jacking Machine" with the publication number CN220726281 U in the prior art; the application is provided with an upper pressure plate, an auxiliary hydraulic cylinder, a remote wireless module and a lower pressure plate. The rescue personnel remotely control the remote wireless module through the remote wireless module, and the upper pressure plate is started to push the front end of the relay pipe forward. The lower pressure plate slides under the upper pressure plate to prevent soil and slag from entering, so that the initial pipeline can move forward quickly, protect the hydraulic cylinder inside the local body of the pipe jacking machine, and continuously provide the driving force for advancement inside the pipeline. However, in the actual application process, it is impossible to correct the deviation of the tool steel pipe. In the process of long tunnel rescue construction, the large deviation of the excavated tunnel channel affects the rescue efficiency. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in the description of the present invention, "multiple" and "several" mean at least two, for example two, three, etc., unless otherwise clearly and specifically defined.

[0032] See also Figures 1 to 6As shown, the utility model is a rescue machine, comprising a tool steel pipe 1, four groups of propulsion cylinders 2, tunnel segments 4, a reaction frame 5 and an excavation equipment body 6. The four groups of propulsion cylinders 2 are suspended and installed on the inner wall of a pipe mouth on one side of the tool steel pipe 1. The propulsion cylinders 2 are symmetrically arranged in pairs on both sides of the vertical center line of the tool steel pipe 1, and the interval angle between adjacent propulsion cylinders 2 is 90°. The tunnel segments 4 are used for laying support along the tunnel channel wall formed by excavation, and the tunnel segments 4 are used to conflict with the telescopic ends of the propulsion cylinders 2. The tunnel segments 4 are laid and installed on the outer contour surface of the reaction frame 5, and the excavation equipment body 6 positions and fixes the reaction frame 5 at one end away from the propulsion cylinder 2, wherein the four groups of propulsion cylinders 2 share an oil supply system, or respectively correspond to an oil supply system.

[0033] During the operation of the rescue machine of the present application, the tool steel pipe 1 is arranged corresponding to the excavation position of the excavated tunnel body 7. When the thrust cylinder 2 is extended, the excavation equipment body 6 limits one end of the reaction frame 5 so that the tunnel segment 4 installed on the reaction frame 5 generates a reverse force on the thrust cylinder 2, so that the thrust cylinder 2 and the tool steel pipe 1 as a whole penetrate the excavated tunnel body 7, thereby facilitating the transfer of the debris from the tool steel pipe 1 out of the excavated rescue tunnel. The operation is convenient, the rescue time can be shortened, and the life safety of the trapped persons is guaranteed to a great extent.

[0034] During the excavation and advancement process of the rescue machine of the present application, the four groups of propulsion cylinders 2 are evenly distributed on the tool steel pipe 1. When the four groups of propulsion cylinders 2 are driven by a common oil supply system, it can be ensured that the four groups of propulsion cylinders 2 extend and retract in unison, so that the tool steel pipe 1 can advance evenly in tunnel excavation. When the tool steel pipe 1 deviates during tunnel excavation, the four groups of propulsion cylinders 2 can be driven by a corresponding oil supply system. For example, if the tool steel pipe 1 deviates to the right, the extension and retraction actions of the propulsion cylinders 2 on the upper left and lower left sides can be driven and controlled at the same time, thereby realizing the deviation correction function of the tool steel pipe 1, ensuring that the rescue tunnel excavation path is carried out accurately, thereby improving the rescue efficiency.

[0035] In this specific implementation mode, Figure 2 and Figure 3 As shown, the rear end of the piston rod 20 of the thrust cylinder 2 has an arc-shaped end face, and the arc-shaped end face of the rear end of the piston rod 20 is adapted to be snap-fitted and installed with the cylinder end cover 21, and the arc-shaped end face of the piston rod 20 is connected and fixed to the cylinder end cover 21 by a screw 8 with a step column, so that the cylinder end cover 21 is conveniently connected to the arc-shaped end face, and is also used for deviation correction and adjustment of the tool steel pipe 1 during excavation. The cylinder end cover 21 is used to contact with the tunnel segment 4 to generate a reverse force on the thrust cylinder 2, so that during the continuous excavation process, the reaction frame 5 and the tunnel segment 4 are continuously lengthened, and the tunnel excavation operation can be continuously advanced forward.

[0036] In this specific implementation mode, Figure 2 and Figure 3 As shown, the threaded hole opened on the arc-shaped end face of the piston rod 20 is matched with the tail end of the screw 8 with the step column, and the stepped hole diameter opened on the cylinder end cover 21 is larger than the diameter of the screw 8 with the step column; during the deviation correction adjustment process of the tool steel pipe 1, the tool steel pipe 1 and the tunnel segment 4 form a deviation angle. At this time, the cylinder end cover 21 can slide along the arc-shaped end face of the piston rod 20 to adjust the movable gap, so that the thrust cylinder 2 and the cylinder end cover 21 have a slight free movement. During the adjustment process, the cylinder end cover 21 can always be in contact with the tunnel segment 4, thereby ensuring that a stable deviation correction adjustment reverse force is generated on the thrust cylinder 2.

[0037] In this specific implementation manner, as shown in Figure 4, the propulsion cylinder 2 is suspended and installed on the inner wall of the pipe mouth of the tool steel pipe 1 through a clamp 9, so that the propulsion cylinder 2 is convenient to be suspended and installed.

[0038] In this specific embodiment, as shown in 2, the end of the thrust cylinder 2 away from the piston rod 20 is fixedly connected to the inclined excavation blade 3. The inclined excavation blade 3 can make it easier for the tool steel pipe 1 to cut into the excavated tunnel body 7, trim the irregular tunnel dug by humans, and at the same time reduce the forward thrust of the thrust cylinder 2.

[0039] In this specific implementation mode, Figure 4 As shown, the thrust cylinder 2 is connected to the hydraulic pump station equipment 10 or the excavation equipment body 6 through the oil supply system. When the thrust cylinder 2 is connected to the hydraulic pump station equipment 10 through the oil supply system, the hydraulic pump station equipment 10 is arranged on the inner wall of the tool steel pipe 1; so that the thrust cylinder 2 can obtain two kinds of power sources, one is to use a 380V power supply to provide electrical energy to the hydraulic pump station equipment 10, and the oil supply system can control the extension and retraction of the thrust cylinder 2 through a four-way manual reversing valve; the second is to use the excavation equipment body 6 instead of the hydraulic pump station equipment 10 to supply oil, and the oil supply system is connected with a three-way conversion joint, so as to facilitate the control of the extension and retraction of the thrust cylinder 2 through the four-way manual reversing valve.

[0040] It should be understood that the structure of the reaction frame 5 is a steel frame structure, the upper part of which is open so that earth trucks and tunnel segments 4 can be lifted out and lifted in from the upper part of the reaction frame 5; a pedestrian passage is provided on one side of the reaction frame 5, through which workers can enter and exit the tunnel.

[0041] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
