[0001] This utility model relates to the field of tunnel inspection technology, and in particular to a guide wheel mechanism and a guide wheel-type tunnel tapping device. Background Technology

[0002] In tunnel construction, the stable operation and precise positioning of various construction equipment are crucial. Past tunnel construction equipment guide wheel mechanisms have limitations and are unable to meet the complex construction demands of today.

[0003] Traditional guide wheel mechanisms consist of a fixed guide wheel frame with two guide wheels for guiding the structure. However, in practical applications, certain problems exist. Firstly, the frame itself cannot guarantee perpendicularity to the tunnel surface, meaning typically only one guide wheel is in contact with the surface. Furthermore, when encountering obstacles on the tunnel surface, it often gets stuck, requiring a large forward force to overcome them, leading to excessive stress and deformation of the mechanism. Secondly, the frame cannot guarantee that the direction of the guide wheels is the same as the overall forward direction of the structure, especially in curved tunnels where the vehicle's forward direction differs from the guide wheel direction. This results in lateral forces on the structure, potentially causing mechanical damage.

[0004] Therefore, there is an urgent need for a guide wheel mechanism to solve the problems of poor adaptability and insufficient directional deviation compensation capability of traditional mechanisms in the complex environment of tunnels, thereby improving the operational stability, operation accuracy and construction efficiency of tunnel construction equipment and promoting the advancement of tunnel engineering construction technology.

[0021] The guide wheel mechanism of this utility model includes a base, a connecting member on the base, and a guide wheel frame rotatably connected to the connecting member. The guide wheel frame and the connecting member are connected by a rotating shaft. The guide wheel frame includes a first end and a second end, which have opposite movement tendencies as the guide wheel frame rotates. A first guide wheel, which is an omnidirectional wheel, a Mecanum wheel, or a universal wheel, is connected to the first end. A second guide wheel, which is also an omnidirectional wheel, a Mecanum wheel, or a universal wheel, is connected to the second end. By utilizing the opposite movement tendencies of the first and second ends when the guide wheel frame rotates, the guide wheel mechanism can be flexibly adjusted at different angles without the need for maintenance. The perpendicularity between the guide wheel and the tunnel surface allows for simultaneous contact between the first and second guide wheels and the tunnel surface, improving the flexibility and adaptability of the guide wheel mechanism.

[0026] Figure 5 This is a schematic diagram of the guide wheel mechanism in another embodiment of the present invention. Detailed Implementation

[0027] As can be seen from the background technology, existing guide wheel mechanisms cannot meet the needs for flexible positioning and direction adjustment in complex environments.

[0028] The inventors discovered that by utilizing the opposing motion trends of the first and second ends when the guide wheel frame rotates, the guide wheel mechanism can be flexibly adjusted at different angles. It can simultaneously achieve contact between the first and second guide wheels and the tunnel surface without ensuring perpendicularity, improving the flexibility and adaptability of the guide wheel mechanism. This allows the guide wheel mechanism to better conform to the working surface in complex environments, better adapt to the unevenness of the tunnel surface, and improve the stability and working efficiency of the equipment. Furthermore, the first guide wheel can be an omnidirectional wheel, a Mecanum wheel, or a universal wheel, and the second guide wheel can also be an omnidirectional wheel, a Mecanum wheel, or a universal wheel, allowing the guide wheel mechanism to move freely in multiple directions, flexibly adjust its direction, eliminate lateral forces, reduce damage to the guide wheel mechanism, and extend its service life, thus having a wide range of applications.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] First, please refer to Figure 1 and Figure 2 A guide wheel mechanism 100 includes a base 101, a guide wheel frame 102, a first guide wheel 103, and a second guide wheel 104.

[0031] In this embodiment, the guide wheel frame 102 is rotatably connected to the base 101. The guide wheel frame 102 has a first end 102-1 and a second end 102-2, which have opposite movement tendencies as the guide wheel frame 102 rotates. The first guide wheel 103 is connected to the first end 102-1, and the second guide wheel 104 is connected to the second end 102-2.

[0032] In this embodiment, the first end 102-1 and the second end 102-2 have opposite motion tendencies as the guide wheel frame 102 rotates. This motion tendency is like a seesaw; when the first end 102-1 of the guide wheel frame 102 is pressed down by force, the second end 102-2 of the guide wheel frame 102 will be lifted up. In this way, even when encountering a curved tunnel surface, the surfaces of the first guide wheel 103 and the second guide wheel 104 can simultaneously contact the surface of the tunnel. Thus, the guide wheel mechanism 100 does not need to be perpendicular to the tunnel surface at all times during operation. This design allows for immediate operation, expanding the applicability of the guide wheel mechanism 100. Furthermore, under any circumstances, if one end (first end 102-1 or second end 102-2) of the guide wheel frame 102 is pressed down, the other end of the guide wheel frame 102 will be raised, improving the obstacle-crossing ability of the guide wheel frame. Moreover, the forward direction of the guide wheel frame 102 does not need to be completely consistent with the forward direction of the first guide wheel 103 or the second guide wheel 104, reducing the lateral force on the guide wheel frame, thereby reducing damage to the guide wheel frame and extending its service life.

[0033] In this embodiment, when the guide wheel frame 102 rotates, the opposite movement trends of the first end 102-1 and the second end 102-2 can enable the guide wheel mechanism 100 to be flexibly adjusted at different angles, thereby improving the flexibility and adaptability of the guide wheel mechanism 100. This allows the guide wheel mechanism 100 to better conform to the working surface in complex environments, such as in tunnel construction, where it can better adapt to the unevenness of the tunnel surface, thus improving the stability and working efficiency of the equipment.

[0034] In this embodiment, please refer to the reference. Figure 1 and Figure 3 The base 101 has a connector 107, and the guide wheel frame 102 is connected to the connector 107 via a rotating shaft 106.

[0035] In this embodiment, please refer to the reference. Figure 1 and Figure 2 It also includes: a reinforcing rib 105 located on the surface of the guide wheel frame 102. The first guide wheel 103, the second guide wheel 104 and the reinforcing rib 105 are located on the same side of the guide wheel frame 102, which can make the structure of the guide wheel mechanism more compact, optimize the spatial layout, and enhance the overall stability of the guide wheel frame 102 under stress.

[0036] In this embodiment, there are two guide wheel frames 102, with the first guide wheel 103 and the second guide wheel 104 located between the two guide wheel frames 102.

[0037] In some embodiments, at least one of the first guide wheel 103, the second guide wheel 104, and the reinforcing rib 105 located on the same side of the guide wheel frame 102 may be located on different sides.

[0038] In this embodiment, the number of rotating shafts 106, the number of guide wheel frames 102, and the number of connecting members 107 correspond one-to-one, with one guide wheel frame 102 and one connecting member 107 paired with one rotating shaft 106 to achieve a rotatable connection.

[0039] Of course, in some embodiments, the guide wheel frame 102 and the connector 107 can be rotatably connected in a manner other than the rotating shaft 106.

[0040] In this embodiment, two guide wheel frames 102 and two corresponding connecting members 107 are used as examples for illustration. The rotating shaft 106 includes a first rotating shaft 106-1 and a second rotating shaft 106-2. The guide wheel frame 102 includes a first guide wheel frame 102-3 and a second guide wheel frame 102-4. The connecting member 107 includes a first connecting member 107-1 and a second connecting member 107-2. The reinforcing rib 105 includes a first reinforcing rib 105-1 and a second reinforcing rib 105-2.

[0041] Of course, in some embodiments, the number of guide wheel frames 102, the number of connectors 107, the number of rotating shafts 106, and the number of reinforcing ribs 105 may be other numbers.

[0042] In this embodiment, please continue to refer to Figure 1 and Figure 2 The guide wheel frame 102 includes a first guide wheel frame 102-3 and a second guide wheel frame 102-4. The first guide wheel frame 102-3 and the second guide wheel frame 102-4 are symmetrically rotatably connected to the base 101. This symmetrical double guide wheel frame structure improves the balance and stability of the guide wheel mechanism 100. The symmetrical connection allows the guide wheel mechanism 100 to distribute the load more evenly when under stress, reducing deformation or damage caused by excessive force on one side. During movement, the symmetrical guide wheel frames 102 better maintain contact with the working surface, improving the smoothness and accuracy of the movement.

[0043] In this embodiment, please refer to the reference. Figure 1 and Figure 3 The base 101 includes a base plate 108, on which a first connector 107-1 and a second connector 107-2 are provided. The first connector 107-1 is rotatably connected to the first guide wheel frame 102-3, and the second connector 107-2 is rotatably connected to the second guide wheel frame 102-4.

[0044] In this embodiment, the base 101 also has a through hole 109 for the hammer head to pass through.

[0045] In this embodiment, please refer to the reference. Figure 1 The surface of the base plate 108 is also connected to a guide tube 110. The guide tube 110 is hollow inside. One end of the guide tube 110 passes through the through hole 109. The hammer head protrudes from one end of the guide tube 110 onto the surface of the guide tube 110 to strike the surface of the tunnel to check whether there is a cavity between the tunnel wall and the soil and rock layer outside the tunnel wall.

[0046] In this embodiment, the guide tube 110 and the connector 107 are located on opposite surfaces of the base plate 108.

[0047] In this embodiment, the first connecting member 107-1 is detachably connected to the base plate 108, specifically, it can be a bolted connection. This detachable connection facilitates the replacement of the first connecting member 107-1 or the base plate 108, improving the maintainability and repairability of the guide wheel mechanism 100. Furthermore, the bolted connection allows for precise adjustment of the relative position between the guide wheel frame 102 and the base 101, ensuring good contact between the guide wheel and the working surface and the operating accuracy of the equipment. In addition, the bolted connection is a standardized connection method with good versatility. Bolts of different specifications can be applied to guide wheel mechanisms 100 of various sizes and types, allowing users to select and replace them according to actual needs. Simultaneously, this connection method also facilitates integration and assembly with other components, improving the overall compatibility of the equipment.

[0048] In this embodiment, the second connector 107-2 is detachably connected to the base plate 108, specifically, it can be a bolt connection.

[0049] In some embodiments, the first connector 107-1 and the base plate 108 may be integrally formed, and the second connector 107-2 and the base plate 108 may also be integrally formed.

[0050] In this embodiment, the first connecting member 107-1 has a first connecting hole 107-1a penetrating through the first connecting member 107-1, and the second connecting member 107-2 has a second connecting hole 107-2a penetrating through the second connecting member 107-2. The line connecting the first connecting hole 107-1a and the second connecting hole 107-2a is perpendicular to the plane of the guide wheel frame 102. This design, where the connecting line is perpendicular to the plane of the guide wheel frame 102, ensures that the motion trajectory of the guide wheel frame 102 during rotation is consistent with the expectation, thus improving the motion accuracy of the guide wheel mechanism 100. This perpendicular distribution also helps to reduce the swaying and offset of the guide wheel frame 102 during rotation, enhancing the stability of the mechanism.

[0051] In some embodiments, the line connecting the first connecting hole 107-1a and the second connecting hole 107-2a has a certain angle with the plane where the guide wheel frame 102 is located, which is not necessarily a right angle.

[0052] In this embodiment, the first guide wheel frame 102-3 has a third connecting hole 102-3a penetrating through the first guide wheel frame 102-3, and the second guide wheel frame 102-4 has a fourth connecting hole 102-4a penetrating through the second guide wheel frame 102-4. The first rotating shaft 106-1 penetrates the first connecting hole 107-1a and the third connecting hole 102-3a, and the second rotating shaft 106-2 penetrates the second connecting hole 107-2a and the fourth connecting hole 102-4a. This connection method can improve the movement flexibility and stability of the guide wheel mechanism 100. At the same time, the through connection of the rotating shaft 106 can withstand a large load, ensuring the reliable operation of the guide wheel mechanism 100 under heavy load conditions. In addition, this structure also helps to reduce wear between connecting parts and extend the service life of the guide wheel mechanism 100.

[0053] In this embodiment, please refer to the reference. Figure 1 and Figure 2 The system also includes a first reinforcing rib 105-1 on the surface of the first guide wheel frame 102-3 facing the second guide wheel frame 102-4, and a second reinforcing rib 105-2 on the surface of the second guide wheel frame 102-4 facing the second guide wheel frame 102-4. This significantly improves the strength and rigidity of the guide wheel frame 102, preventing deformation under stress. The reinforcing rib 105 not only enhances the overall structure of the guide wheel frame 102 but also enables it to withstand greater loads, improving the load-bearing capacity of the guide wheel mechanism 100. Simultaneously, the reinforcing rib 105 helps to disperse the connection stress between the guide wheel frame 102 and the base 101, reducing stress concentration and extending the service life of the guide wheel mechanism 100.

[0054] In this embodiment, the first reinforcing rib 105-1 and the second reinforcing rib 105-2 are located on both sides of the through hole.

[0055] In this embodiment, the first reinforcing rib 105-1 has a first reinforcing rib connecting hole (not marked in the figure) corresponding to the first connecting hole 107-1a, and the second reinforcing rib 105-2 has a second reinforcing rib connecting hole (not marked in the figure) corresponding to the second connecting hole 107-2a. The first rotating shaft 106-1 passes through the first reinforcing rib connecting hole (not marked in the figure), and the second rotating shaft 106-2 passes through the second reinforcing rib connecting hole (not marked in the figure). The rotating shaft 106 (the first rotating shaft 106-1 and the second rotating shaft 106-2) passes through the connecting hole on the reinforcing rib 105 (the first reinforcing rib 107-1a). The first reinforcing rib connecting hole and the second reinforcing rib connecting hole further enhance the connection strength between the guide wheel frame 102 and the base 101. This structure can improve the stability and reliability of the guide wheel mechanism 100, while ensuring that the guide wheel frame 102 can maintain a tight fit with the base 101 during rotation. The reinforcing rib 105 connecting holes (first reinforcing rib connecting hole 105-1a and second reinforcing rib connecting hole 105-2a) on the reinforcing rib 105 can also play a guiding role, making the installation of the rotating shaft 106 (first rotating shaft 106-1 and second rotating shaft 106-2) more accurate and convenient.

[0056] In this embodiment, there is a gap between the reinforcing rib 105 and the surface of the guide wheel frame 102. For details, please refer to the reference. Figure 1 and Figure 2 There is a first gap 105-1a between the surface of the first reinforcing rib 105-1 and the surface of the first guide wheel frame 102-3, and there is a second gap 105-2a between the surface of the second reinforcing rib 105-2 and the surface of the second guide wheel frame 102-4.

[0057] In some embodiments, the reinforcing rib 105 may also be a flat reinforcing plate, and there is no gap between the reinforcing rib 105 and the surface of the guide wheel frame 102.

[0058] In this embodiment, the connector 107 includes a fixing portion 107a and a protrusion 107b protruding from the surface of the fixing portion 107a. The protrusion 107b is located in the gap between the reinforcing rib 105 and the surface of the guide wheel frame 102. Specifically, the first connector 107-1 includes a first fixing portion 107-1b and a first protrusion 107-1c protruding from the surface of the first fixing portion 107-1b, and the first connecting hole 107-1a is located on the first protrusion 107-1c; the second connector 107-2 includes a second fixing portion 107-2b and a protrusion 107b protruding from the surface of the fixing portion 107a. The second protrusion 107-2c on the surface of the second fixing part 107-2b, the second connecting hole 107-2a located on the second protrusion 107-2b, the first protrusion 107-1c located within the first gap 105-1a, and the second protrusion 107-2c located within the second gap 105-2a. The design of the gaps (the first gap 105-1a and the second gap 105-2a) provides a certain space for the deformation and movement of the guide wheel frame 102, avoiding structural damage caused by excessive compression between the reinforcing rib 105 and the surface of the guide wheel frame 102. At the same time, the existence of the gaps can reduce the weight of the guide wheel frame 102 and reduce the inertia of the guide wheel mechanism 100, making it more sensitive and flexible during movement. Furthermore, the gap can accommodate some lubricant, reducing friction between connecting parts and improving the operating efficiency of the guide wheel mechanism 100. The design of the protrusions 107b (the first protrusion 107-1c and the second protrusion 107-2c) can increase the contact area between the connector 107 and the guide wheel frame 102, increasing the stability of the connection. At the same time, the protrusions 107b located within the gap can act as a limit, preventing the guide wheel frame 102 from swinging excessively during movement. In addition, this structure can also improve the compactness and aesthetics of the guide wheel mechanism 100, enabling it to better perform its functions within a limited space.

[0059] In this embodiment, the surface of the guide wheel frame 102 facing the base 101 is recessed 111 in a direction perpendicular to the surface of the base 101; the width of the recess 111 is greater than or equal to the width of the base 101 in the extending direction parallel to the guide wheel frame 102. The recess 111 design increases the distance between the guide wheel frame 102 and the base 101, thereby providing the guide wheel frame 102 with maximum rotational stroke. Furthermore, this structure can reduce friction between the guide wheel frame 102 and the base 101, improving the movement flexibility of the guide wheel mechanism 100.

[0060] In this embodiment, the depth of the recess 111 is h.

[0061] In this embodiment, the first guide wheel 103 is an omnidirectional wheel, a Mecanum wheel, or a caster wheel; the second guide wheel 104 is an omnidirectional wheel, a Mecanum wheel, or a caster wheel. Omnidirectional wheels, Mecanum wheels, or caster wheels have good motion flexibility and directional control capabilities. Omnidirectional wheels, Mecanum wheels, or caster wheels themselves have the ability to move in multiple directions, and the rotation of the guide wheel frame further enhances the flexibility of the entire mechanism in space, allowing it to easily change direction and position in complex environments and adapt to various irregular motion requirements. This type of guide wheel is particularly suitable for use in narrow or irregular spaces, such as in tunnel construction, where it can improve the mobility and ease of operation of the equipment.

[0062] In other embodiments, please refer to Figure 5 It also includes: an auxiliary support plate 112 connected to the base, the auxiliary support plate 112 and the guide wheel frame 102 being located on opposite surfaces of the base 101, the auxiliary support plate 112 and the base 101 being rotatably connected via an auxiliary rotating shaft 113, the auxiliary support plate 112 swinging around the auxiliary rotating shaft 113 along a second direction X, and the guide wheel frame 102 swinging around the rotating shaft 106 along a first direction Y, the first direction Y being perpendicular to the second direction X; the base 101 has four guide wheel frames 102, two guide wheel frames being respectively connected to the sides of the first guide wheel 103 and the second guide wheel 104 to form two guide wheel groups 114, the two guide wheel groups 114 being respectively located on both sides of the through hole 109; this design adds an auxiliary support function to the guide wheel mechanism, improving the mechanism's movement capability and stability in different directions. The auxiliary support plate 112 can swing in the second direction, cooperating with the movement of the guide wheel frame 102 in the first direction. This allows the entire mechanism to achieve more complex and flexible multi-directional movements (forward and backward, left and right), greatly expanding its application range and functionality. It can better adapt to various complex working scenarios and motion requirements, meeting the needs of different users. Furthermore, this layout makes the force on the guide wheel mechanism more even during load-bearing and movement, effectively improving the stability and load-bearing capacity of the mechanism. The synergistic effect of multiple guide wheel frames 102 can better distribute the load, reducing the pressure on a single guide wheel frame, thereby extending the service life of the mechanism. At the same time, it can also ensure the stability and reliability of the mechanism during operation, making it better suited for the use of heavier loads or larger-sized components such as hammers, further enhancing the practicality and adaptability of the guide wheel mechanism.

[0063] Accordingly, this utility model also provides a guide wheel type tunnel hammering device 200, please refer to it. Figure 4 This includes the aforementioned guide wheel mechanism 100.

[0064] In this embodiment, a hammerhead 201 is also included. The hammerhead 201 is located within the through hole 109 and is retractable. The guide wheel mechanism 100 is responsible for the positioning and movement of the equipment, while the hammerhead 201 is responsible for the striking operation. The retractable movement of the hammerhead 201 ensures the accuracy of the striking operation and the effectiveness of the force transmission. This design also improves the space utilization of the equipment, making the equipment structure more compact.

[0065] In this embodiment, the hammerhead 201 is located between the two guide wheel frames 102 (i.e., the first guide wheel frame 102-3 and the second guide wheel frame 102-4). The guide wheel frames 102 can better guide and stabilize the running trajectory of the hammerhead, and the hammerhead 201 may generate impact force when it is working. The hammerhead 201 located between the guide wheel frames 102 can disperse some of the impact force through the guide wheel frames 102. The guide wheel frames 102 can act as a buffer, reducing the damage of the impact force to the hammerhead 201 itself and the connecting parts. This is like setting a "shock-absorbing zone" around the hammerhead 201, extending the service life of the hammerhead 201 and related components.

[0066] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
