Description

Technical Field

[0001] This utility model relates to the field of tunneling machine disassembly and assembly technology, and in particular to an auxiliary disassembly and assembly mechanism for tunneling machines. Background Technology

[0002] Tunnel boring machines (TBMs) can perform continuous cutting, loading, and transport operations, and are widely used in tunneling coal roadways, semi-coal-rock roadways, and soft rock roadways with large dip angles. They can also be used in tunnels for railways, highways, and hydraulic engineering projects. After one cycle of use underground in a coal mine, a TBM needs to be brought to the surface for maintenance.

[0003] The existing method of connecting the parts to be disassembled and assembled in a tunneling machine to the main body is through four pins: two cutting arm pins and two lifting cylinder pins. Since the weight of the parts to be disassembled and assembled in a tunneling machine is generally between 12 and 16 tons, these four pins are prone to slipping, accidental falling of cylinders, and people getting their hands caught during disassembly and installation.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model claims protection for an auxiliary installation and dismantling mechanism for a tunneling machine, including a bracket, a main adjustment component, and an auxiliary adjustment component. The bracket is provided with an arc-shaped placement part, which is adapted to the shape of the part to be dismantled or installed. The main adjustment component and the auxiliary adjustment component are provided at the bottom of the bracket. The main adjustment component and the auxiliary adjustment component drive the bracket to move vertically. The main adjustment component is configured to adjust the height of the part to be dismantled or installed, and the auxiliary adjustment component is configured to adjust the alignment of the part to be dismantled or installed with the corresponding installation point of the main unit.

[0008] Preferably, the bracket is a U-shaped frame structure, and the opening of the U-shaped frame is adapted to the shape of the outer surface of the part to be disassembled or assembled, wherein the opening of the U-shaped frame forms an arc-shaped placement part.

[0010] Preferably, the main adjustment component is a hydraulic cylinder, and there are at least four hydraulic cylinders arranged diagonally on the upper surface of the base plate, wherein the piston rod of the hydraulic cylinder constitutes the output end of the main adjustment component.

[0011] Preferably, the auxiliary adjustment component is a jack, with the jack located at the center of the top surface of the base plate, and the output end of the jack connected to the center of the bottom surface of the bracket.

[0012] Preferably, the bracket is hollow inside, and a first reinforcing rib is provided inside the bracket.

[0013] Preferably, the part to be disassembled includes a part body and a mounting base. The part body is disposed inside the opening of the U-shaped frame. The axis of the part body is horizontal. The mounting base is coaxially disposed at the end of the part body. The mounting base passes through the first pin hole along the axial direction.

[0017] The advantages of this utility model are:

[0018] I. This utility model, by setting an arc-shaped placement part, can stably support the part to be disassembled and assembled. In conjunction with the main adjustment component and the auxiliary adjustment component, both the main adjustment component and the auxiliary adjustment component adjust the vertical movement of the part to be disassembled and assembled. The main adjustment component is mainly used to adjust the height of the part to be disassembled and assembled by a large amount, while the auxiliary adjustment component is mainly used to make fine adjustments after the main adjustment component has adjusted the approximate height. The auxiliary adjustment component precisely adjusts the alignment of the corresponding installation points of the part to be disassembled and assembled with the main unit. The two work together and complement each other to adjust the alignment of the part to be disassembled and assembled with the main unit, so as to realize the rapid disassembly and assembly of the part to be disassembled and assembled with the main unit.

[0019] Second, the bracket is preferably a U-shaped frame structure. The U-shaped frame opening is adapted to the shape of the outer surface of the part to be disassembled or assembled, so as to provide stable support for the part to be disassembled or assembled and avoid shaking and slippage of the part to be disassembled or assembled during the adjustment process.

[0020] Third, the main adjustment components are preferably four in number and arranged diagonally on the upper surface of the base plate. This ensures that the supporting force on the parts to be disassembled and assembled is balanced, preventing deviation during the adjustment process. In addition, the bottom sides of the bracket are flanged. On the one hand, the flanges can provide sufficient installation space for the output end of the main adjustment components. On the other hand, the flanges can ensure that the overall weight of the bracket is small, thus ensuring the lightness of the entire auxiliary installation and disassembly mechanism of the tunneling machine.

[0021] Fourth, the hollow interior of the bracket also ensures the ease of installation and removal of the tunneling machine's auxiliary installation and removal mechanism; together with the first reinforcing rib, it can provide good support for the bracket, ensuring ease of installation while also increasing the strength of the support.

[0022] Fifth, by setting a second reinforcing rib, the support strength of two adjacent legs can be guaranteed, so that the base plate and the legs together form a stable bracket, which is not only very lightweight and easy for personnel to lift, but also highly stable and can guarantee the support strength of the parts to be disassembled.

[0023] VI. The preferred jack is a screw jack. In fact, the screw jack achieves adjustment through screw engagement, thus providing high adjustment accuracy, which is conducive to the precise alignment of the corresponding installation points of the part to be disassembled and the main unit.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figures 1 to 3This utility model claims protection for an auxiliary installation and dismantling mechanism for a tunneling machine, including a bracket 1, a main adjustment component 2, a base plate 4, and an auxiliary adjustment component 3. The bracket 1 is provided with an arc-shaped placement part, which is adapted to the shape of the part to be dismantled or assembled; it provides stable support for the part to be dismantled or assembled, and avoids shaking and slippage of the part to be dismantled or assembled during the adjustment process. The bracket 1 has a U-shaped frame structure, the inside of the bracket 1 is hollow, and a first reinforcing rib 11 is provided inside the bracket 1. The hollow interior of the bracket 1 also ensures the lightweight nature of the auxiliary installation and dismantling mechanism for the tunneling machine. In conjunction with the first reinforcing rib 11, the bracket 1 provides excellent support, ensuring lightweight construction while enhancing structural strength. The U-shaped frame opening is designed to fit the outer surface of the part to be disassembled, forming an arc-shaped placement area. The bottom of the bracket 1 is equipped with a main adjustment component 2 and an auxiliary adjustment component 3. Flanges 10 are formed on both sides of the bottom of the bracket 1. A base plate 4 is positioned directly below the bracket 1, with legs 40 positioned at the corners of the bottom surface of the base plate 4. The legs 40 are perpendicular to the base plate 4, and a second... The reinforcing rib 41, by setting the second reinforcing rib 41, can ensure the support strength of the two adjacent support legs 40, so that the base plate 4 and the support legs 40 together form a stable support. It is not only very lightweight and easy for personnel to lift, but also highly stable, and can ensure the support strength of the part to be disassembled. The main adjustment components 2 are placed on both sides of the upper surface of the base plate 4. The output end of the main adjustment components 2 is connected to the flange 10. The main adjustment components 2 and the auxiliary adjustment components 3 drive the bracket 1 to move vertically. The main adjustment components 2 are configured to adjust the height of the part to be disassembled. The main adjustment components 2 are hydraulic cylinders, and there are at least four hydraulic cylinders arranged diagonally on the upper surface of the base plate 4. In this way, the support force of the part to be disassembled is balanced, and the deviation is avoided during the adjustment process. Moreover, flanges 10 are formed on both sides of the bottom of the bracket 1. On the one hand, the flanges 10 can reserve sufficient installation space for the output end of the main adjustment components 2. On the other hand, the setting of the flanges 10 can ensure that the overall weight of the bracket 1 is small, thereby ensuring the lightness of the entire tunneling machine auxiliary installation and disassembly mechanism. The hydraulic cylinder piston rod forms the output end of the main adjustment component 2. The auxiliary adjustment component 3 is configured to adjust the alignment of the corresponding mounting points of the part to be disassembled and the main unit. The part to be disassembled includes the part body and the mounting seat. The part body is set inside the opening of the U-shaped frame. The axis of the part body is horizontal. The mounting seat is coaxially set at the end of the part body. The mounting seat passes through the first pin hole along the axial direction. The end of the main unit is correspondingly set with a second pin hole. The second pin hole and the first pin hole together form the mounting point. The auxiliary adjustment component 3 is a jack. The jack is a screw jack. In fact, the screw jack achieves adjustment through thread engagement. Therefore, the adjustment accuracy is high, which is conducive to the fine processing of the alignment of the corresponding mounting points of the part to be disassembled and the main unit. The jack is set at the center of the top surface of the base plate 4. The output end of the jack is connected to the center of the bottom surface of the bracket 1.

[0030] This utility model, by setting an arc-shaped placement part, can stably support the part to be disassembled and assembled. In conjunction with the main adjustment component 2 and the auxiliary adjustment component 3, both the main adjustment component 2 and the auxiliary adjustment component 3 adjust the vertical movement of the part to be disassembled and assembled. The main adjustment component 2 is mainly used to adjust the height of the part to be disassembled and assembled significantly, while the auxiliary adjustment component 3 is mainly used for fine adjustment after the main adjustment component 2 has adjusted the approximate height. The auxiliary adjustment component 3 precisely adjusts the alignment of the corresponding installation points of the part to be disassembled and assembled with the main unit. The two work together to adjust the alignment of the part to be disassembled and assembled with the main unit, so as to achieve rapid disassembly and assembly of the part to be disassembled and assembled with the main unit.

[0031] Based on this, an application scenario for an auxiliary installation and dismantling mechanism for a tunneling machine is provided, specifically for the dismantling and assembly of the cutting section and the main frame of the tunneling machine. The section to be dismantled is preferably the cutting section, and the main frame is preferably the main frame. In actual operation, it is preferred to work with a traveling crane. The hydraulic cylinder is preferably connected to the high-pressure side of the emulsification pump through a hose, and a manual operating valve is arranged on the hose. During use, the hydraulic cylinder is opened and closed by personnel operating the manual operating valve, thereby causing the output end of the hydraulic cylinder, i.e., the piston rod of the hydraulic cylinder, to move up and down. This is existing technology and will not be described in detail.

[0032] The specific operation includes the following steps:

[0033] Step 1: Place the auxiliary installation and dismantling mechanism of the tunneling machine. Place the auxiliary installation and dismantling mechanism in front of the main frame installation site, generally between 1.5 and 2.2 meters away from the main shovel plate. The actual placement distance may vary slightly depending on the machine model.

[0034] Step 2: Prepare the hydraulic cylinder by connecting the hose from the high-pressure side of the emulsification pump to the hydraulic cylinder via a manual operating valve.

[0035] Step 3, taking the installation of the cutting unit as an example, mainly involves the installation of the cutting unit and the main frame, which mainly involves the installation of the mounting base and the two first pins at the mounting points on the main frame, as well as the installation of the tunneling machine lifting cylinder and the two second pins at the mounting points on the main frame.

[0036] Therefore, firstly, the first pin is installed by using a crane to smoothly lift the cutting unit and place it in the arc-shaped placement area. At this time, the lifting chain on the cutting unit body can be removed, leaving only the rear lifting chain of the cutting unit. Adjust the center of the crane in the north-south and east-west directions to facilitate the adjustment of the pin hole center of the first pin between the cutting unit and the main frame.

[0037] Secondly, when the height of the cutting section is too high or too low, the extension height of the hydraulic cylinder piston rod can be adjusted by manually operating the valve connected to the hydraulic cylinder. This adjusts the height of the cutting section.

[0038] Secondly, after adjusting the height, the center of the pin hole of the first pin shaft of the cutting part and the main frame can be further adjusted and aligned with the center of the pin hole using a screw jack, and the first pin shaft can be installed.

[0039] Finally, due to the fulcrum effect of the tunneling machine's auxiliary installation and dismantling mechanism, the center of the pin holes of the two second pins at the installation point of the main frame can be aligned by using a crane to install the second pins.

[0040] By providing an adjustable-height auxiliary installation and dismantling mechanism for the tunneling machine during the installation and dismantling of the cutting section and the main frame, the overhead crane is freed up, and subsequent close-range manual work is handed over to the crane operator, reducing the need for close-range personnel work. This not only ensures personal safety and reduces labor intensity, but also improves work efficiency and ensures safe production.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
