[0052] 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 with reference to the accompanying drawings. 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.

[0053] The following is combined Figures 1 to 11 This describes the beam connection assembly 100 provided in the embodiments of the present invention.

[0054] Specifically, the beam connection assembly 100 is used to connect two beams, and the beam connection assembly 100 includes a connecting seat 1, a connecting member 2, and a limiting member 3.

[0055] The connecting seat 1 is connected to the first of the two beams. The connecting seat 1 is provided with a positioning groove 104, the opening of which faces the second of the two beams. Optionally, when the track-walking device is in use, the two beams are arranged along the height direction Z, with the first beam being the lower beam and the second beam being the upper beam. Of course, the first beam can also refer to the upper beam, and correspondingly, the second beam to the lower beam; this is not limited.

[0056] Accordingly, when the track-walking device is in use, the positioning groove 104 extends along the height direction Z in the depth direction. Optionally, the positioning groove 104 extends through the connecting seat 1 in the horizontal direction.

[0057] Connector 2 is connected to the second of the two beams, and connector 2 protrudes from the side wall of the second beam. For example, connector 2 can be configured as a connecting column or connecting rod, and the axial direction of connector 2 is consistent with the protruding direction of connector 2. Optionally, connector 2 can be configured as a cylinder to reduce the processing difficulty of connector 2. Of course, in other embodiments, connector 2 can also be configured as a polygonal prism, and this is not limited.

[0058] Furthermore, the portion of the connector 2 protruding from the side wall of the second beam can pass through the opening of the positioning groove 104 and be disposed within the positioning groove 104, so that the positioning groove 104 can limit the connector 2 in a direction perpendicular to the protrusion direction of the connector 2. Accordingly, the positioning groove 104 is at least opposite to the portion of the connector 2 protruding from the side wall of the second beam, so that the positioning groove 104 can be inserted into the connector 2. Optionally, the opening of the positioning groove 104 can be oriented along the height direction Z, that is, the opening of the positioning groove 104 is directly opposite the second of the two beams. Alternatively, the opening of the positioning groove 104 can also have an angle with the height direction Z, that is, the opening of the positioning groove 104 is inclined.

[0059] Understandably, reference Figure 6 and Figure 7 As shown in the figure, when the beam is placed in the posture shown in the figure, the side wall of the beam refers to the side wall set along the height direction in the figure, that is, the vertical side wall of the connecting piece 2 protruding from the beam.

[0060] The limiting member 3 is closable in the opening of the positioning groove 104, meaning that the limiting member 3 can close or open the opening of the positioning groove 104. When the limiting member 3 closes the opening of the positioning groove 104, the limiting member 3 can limit the connecting member 2 along the direction of the opening of the positioning groove 104, thereby preventing the connecting member 2 from coming out of the opening of the positioning groove 104 and thus preventing the two beams from separating.

[0061] In this embodiment, during actual use, for example, a connecting seat 1 can be provided on the first of the two beams, and a connecting member 2 can be provided on the second of the two beams. When connecting the first and second beams, the limiting member 3 can first open the slot of the positioning groove 104, then the second beam can be hoisted above the first beam, then the second beam can be lowered and the connecting member 2 of the second beam can be placed in the positioning groove 104, and finally the limiting member 3 can close the slot of the positioning groove 104 to prevent the connecting member 2 from coming out of the slot of the positioning groove 104.

[0062] With this configuration, when connecting two beams, the beam connection assembly 100 provided in this embodiment only needs to place the connector 2 on one beam into the positioning groove 104 of the connector seat 1 of the other beam, and then use the limiting member 3 to close the positioning groove 104. Compared with the related technology, which requires aligning the pin holes of the two beams and then passing the pin through the two pin holes, this eliminates the steps of aligning the two pin holes and passing the pin through the two pin holes, thereby reducing the assembly difficulty between beams.

[0063] Optionally, the limiting member 3 can be movably connected to the connecting seat 1, for example, the limiting member 3 can be slidably connected to the connecting seat 1. Specifically, the connecting seat 1 is provided with a connecting hole, and the limiting member 3 can be slidably inserted into the connecting hole to open and close the slot of the positioning groove 104 by sliding.

[0064] Of course, the limiting member 3 is not limited to sliding connection with the connecting seat 1. For example, in some embodiments not shown, the limiting member 3 and the connecting seat 1 can also be rotatably connected or detachably connected by threaded fasteners.

[0065] In some embodiments provided by this utility model, the connector 2 is configured as a connecting shaft, the end of which protrudes from the side wall of the beam and is used to pass through the slot of the positioning groove 104 and engage within the positioning groove 104. This configuration simplifies the structure of the connector 2 and facilitates its processing. For example, the connecting shaft can be welded to the beam. For example, the connecting shaft extends horizontally.

[0066] refer to Figure 4 and Figure 5 As shown, in some embodiments provided by this utility model, the connecting seat 1 includes a base plate 101 and a side plate 102.

[0067] The base plate 101 is connected to the first of the two beams. For example, the base plate 101 can be welded to the beam or connected by threaded fittings.

[0068] There are two side plates 102, which are spaced apart on the base plate 101. Optionally, both side plates 102 are welded to the base plate 101. Optionally, the arrangement direction of the two side plates 102 is consistent with the protruding direction of the connector 2.

[0069] The two ends of the connector 2 protrude from the two opposite side walls of the second, and the two ends of the connector 2 are respectively placed in the positioning grooves 104 of the two side plates 102.

[0070] In this embodiment, both sides of the beam are connected to the corresponding side plate 102 positioning groove 104 via connectors 2, which ensures that the beam is subjected to balanced forces on both sides, avoiding stress concentration that could lead to damage or deformation. Furthermore, the load transmitted between the two beams can be distributed across the two positioning grooves 104, allowing them to share the load and preventing excessive stress concentration in a single positioning groove 104, which could result in damage to the positioning groove 104 or the connector 2.

[0071] In some embodiments provided by this utility model, the beam connection assembly 100 further includes a limiting plate 4.

[0072] The limiting plate 4 is connected to the connecting member 2. For example, the limiting plate 4 can be connected to the connecting member 2 by threaded fasteners or welding. Furthermore, along the protruding direction of the connecting member 2, the limiting plate 4 forms a limiting fit with the connecting seat 1. For example, the limiting plate 4 extends in the radial direction of the connecting member 2, and the cross-sectional area of ​​the limiting plate 4 is larger than the cross-sectional area of ​​the positioning groove 104 to prevent the limiting plate 4 from passing through the positioning groove 104.

[0073] In this embodiment, by limiting the plate 4 along the protruding direction of the connector 2 and cooperating with the connecting seat 1, the connector 2 can be prevented from moving along its own length direction in the positioning groove 104, thereby improving the stability of the beam connection assembly 100 in connecting the two beams.

[0074] Optionally, the two ends of the connector 2 protrude from the two opposite side walls of the second plate, and the two ends of the connector 2 are respectively placed in the positioning grooves 104 of the two side plates 102. Each end of the connector 2 is provided with a limiting plate 4, which is disposed on the outer side of the corresponding side plate 102 and forms a limiting fit with the side plate 102 along the protruding direction of the connector 2.

[0075] In this embodiment, the limiting plates 4 at both ends of the connector 2 are respectively limited and cooperate with the corresponding side plates 102, which can limit the connector 2 in both the protruding direction and the opposite direction of the protruding direction, preventing the connector 2 from sliding in the positioning groove 104 in the protruding direction or the opposite direction of the protruding direction, thereby improving the stability of the beam connection assembly 100 in connecting the two beams.

[0076] In some embodiments provided by this utility model, the surface of the connecting seat 1 facing the second party is provided with a positioning protrusion 105, the positioning protrusion 105 is placed in the positioning recess of the second party, and the positioning protrusion 105 and the positioning recess form a limiting fit along the protrusion direction of the connecting member 2.

[0077] In this embodiment, by providing a positioning protrusion 105 on the connecting seat 1, and by having the positioning protrusion 105 cooperate with the positioning recess of the second in the protruding direction of the connecting member 2, it is possible to prevent the two beams connected by the beam connecting assembly 100 from sliding relative to each other in the protruding direction of the connecting member 2, thereby improving the stability of the beam connecting assembly 100 in connecting the two beams.

[0078] refer to Figure 7 and Figure 8 As shown, in some embodiments provided by this utility model, the connecting seat 1 further includes a reinforcing plate 103.

[0079] A reinforcing plate 103 is provided on at least one surface of the side plate 102, and the reinforcing plate 103 is attached to and connected to the surface of the side plate 102. A positioning groove 104 is also provided at the position corresponding to the positioning groove 104 on the reinforcing plate 103.

[0080] In this embodiment, by providing a reinforcing plate 103 on the side plate 102, the strength and rigidity of the side plate 102 can be improved, avoiding deformation or damage to the side plate 102. On the other hand, the reinforcing plate 103 is also provided with a positioning groove 104, that is, the reinforcing plate 103 and the side plate 102 can jointly support the connector 2, so that the reinforcing plate 103 can share the load with the side plate 102, reducing the problem of damage to the reinforcing plate 103 or the connector 2 due to stress concentration.

[0081] This utility model embodiment also provides a track walking device.

[0082] Specifically, the track-walking device includes a first beam 5, a second beam 6, a walking wheel assembly 7, and the beam connection assembly 100 as described above.

[0083] The first beam 5 and the second beam 6 are connected by a beam connecting assembly 100. For example, the connecting seat 1 of the beam connecting assembly 100 is connected to the second beam 6, and the connecting piece 2 is connected to the first beam 5. The first beam 5 is used to connect the crane boom 14. The traveling wheel assembly 7 is connected to the second beam 6 and is used to travel along the track 15.

[0084] In this embodiment, the track walking device includes the beam connection component 100 provided in this embodiment of the present invention, and also includes all the above-mentioned advantages of the beam connection component 100, so it will not be described again.

[0085] refer to Figure 3 As shown, in some embodiments provided by this utility model, the track walking device further includes a third beam 8.

[0086] The second beam 6 is provided with at least two third beams 8, which are arranged along the walkable direction of the track-walking device, and each third beam 8 is connected to the second beam 6 through a corresponding beam connecting assembly 100. The third beam 8 is provided with at least two walking wheel assemblies 7, which are arranged along the walkable direction of the track-walking device.

[0087] In this embodiment, by setting at least two third beams 8 on the second beam 6, and each third beam 8 is provided with at least two traveling wheel assemblies 7, the installation area of ​​the second beam 6 is increased, so that more traveling wheel assemblies 7 can be set on the second beam 6, thereby increasing the load-bearing capacity of the track traveling device.

[0088] refer to Figure 3 As shown, in some embodiments of this utility model, the number of second beams 6 is at least two. The arrangement direction of the at least two second beams 6 intersects with the walkable direction of the track walking device, and each second beam 6 is connected to the first beam 5 through a corresponding beam connecting assembly 100. Each second beam 6 is provided with a corresponding walking wheel assembly 7. Optionally, each second beam 6 is provided with a corresponding third beam 8.

[0089] In this embodiment, by setting at least two second beams 6 to jointly support the first beam 5, the load transmitted by the first beam 5 can be shared among the at least two second beams 6, reducing the problem of stress concentration in the second beams 6. Each second beam 6 is provided with a corresponding traveling wheel assembly 7, so that the track traveling device has more traveling wheel assemblies 7, thereby increasing the load-bearing capacity of the track traveling device.

[0090] refer to Figure 3 As shown, in some embodiments of this utility model, the track-walking device further includes a slewing bearing 9. The rotation axis of the slewing bearing 9 extends along the height direction of the track-walking device.

[0091] A corresponding slewing bearing 9 is provided between the first beam 5 and the second beam 6, and the slewing bearing 9 is connected between the beam connecting assembly 100 and the second beam 6. For example, one end of the slewing bearing 9 is connected to the beam connecting assembly 100, and the other end is connected to the second beam 6. Alternatively, the slewing bearing 9 is connected between the beam connecting assembly 100 and the first beam 5. For example, one end of the slewing bearing 9 is connected to the beam connecting assembly 100, and the other end is connected to the first beam 5.

[0092] A corresponding slewing bearing 9 is provided between the second beam 6 and the third beam 8, and the slewing bearing 9 is connected between the beam connecting assembly 100 and the third beam 8. For example, one end of the slewing bearing 9 is connected to the beam connecting assembly 100, and the other end is connected to the third beam 8. Alternatively, the slewing bearing 9 is connected between the beam connecting assembly 100 and the second beam 6. For example, one end of the slewing bearing 9 is connected to the beam connecting assembly 100, and the other end is connected to the second beam 6.

[0093] In this embodiment, by providing a slewing bearing 9 between the first beam 5 and the second beam 6, the second beam 6 can swing relative to the first beam 5 around a vertical axis. By providing a slewing bearing 9 between the second beam 6 and the third beam 8, the third beam 8 can swing relative to the second beam 6 around a vertical axis.

[0094] refer to Figure 3 As shown, in some embodiments provided by this utility model, the track walking device further includes a joint bearing 10, and the walking wheel assembly 7 is connected to the third beam 8 through the joint bearing 10.

[0095] In this embodiment, the walking wheel assembly 7 is connected to the third beam 8 via the joint bearing 10, which allows the walking wheel assembly 7 to swing relative to the third beam 8 around the vertical axis and around the horizontal axis, so that the walking wheel assembly 7 can adapt to the height changes of the track 15.

[0096] As described above, the second beam 6 swings relative to the first beam 5 around the vertical axis, the third beam 8 swings relative to the second beam 6 around the vertical axis, and the walking wheel assembly 7 swings relative to the third beam 8 around the vertical axis, so that the track walking device can freely switch between the arc track 15 and the straight track 15.

[0097] For example, refer to Figure 1 and 9 As shown, during the operation of the track-walking device, as it gradually transitions from the curved track 15 to the straight track 15, the second beam 6 and the third beam 8 rotate via corresponding slewing bearings 9, and the traveling wheel assembly 7 rotates via spherical bearings 10. This allows the second beam 6, the third beam 8, and the traveling wheel assembly 7 to adapt to the shape change of the track 15, thus enabling the track-walking device to adapt to the shape change of the track 15 and complete the transition from the curved track 15 to the straight track 15. Similarly, the track-walking device can also move from the straight track 15 to the curved track 15.

[0098] refer to Figure 9 and Figure 10 As shown, in some embodiments provided by this utility model, the walking wheel assembly 7 includes a mounting base 701, a support wheel group, and a limiting wheel 703.

[0099] The mounting base 701 is used to connect to the second beam 6. For example, the mounting base 701 is connected to the second beam 6 via the third beam 8, and the mounting base 701 and the third beam 8 are connected by a spherical bearing 10.

[0100] The support wheel assembly includes at least two support wheels 702, which are rotatably and spaced apart from each other on the mounting base 701. Each of the at least two support wheels 702 runs along a corresponding track 15. The arrangement direction of the at least two support wheels 702 intersects the travel direction. Optionally, there are at least two support wheel assemblies, arranged along the travel direction.

[0101] The limiting wheel 703 is located between two adjacent support wheels 702 and is rotatably connected to the mounting base 701. The rotation axis of the limiting wheel 703 intersects with the rotation axis of the support wheel 702. The limiting wheel 703 is used to be installed between two adjacent tracks 15.

[0102] In this embodiment, by including at least two support wheels 702 in the support wheel assembly, the load can be shared among the support wheels 702, avoiding stress concentration on the support wheels 702. By providing a limiting wheel 703 on the traveling wheel assembly 7, and the limiting wheel 703 being located between two adjacent tracks 15, the limiting wheel 703 interacts with the track 15, providing a guiding effect for the traveling wheel assembly 7, allowing the traveling wheel assembly 7 to run on the arc track 15, or switch between the arc track 15 and the straight track 15.

[0103] Furthermore, the traveling wheel assembly also includes a drive unit 704, which is mounted on the mounting base 701 and is connected to the corresponding support wheel 702 for driving the support wheel 702 to rotate. Optionally, each support wheel assembly is provided with a corresponding drive unit 704.

[0104] In some embodiments provided by this utility model, the track walking device further includes a support base 11 and a scraper 12.

[0105] In this configuration, the support base 11 is connected to the front or rear end of the traveling wheel assembly 7 along the travel direction of the track-walking device. For example, the support base 11 is connected to the front or rear end of the mounting base 701.

[0106] The scraper 12 is adjustablely positioned on the support base 11 along the height direction of the track traveling device, and the scraper 12 is used to slide in contact with the track 15.

[0107] In this embodiment, by providing a support base 11 and a scraper 12 on the walking wheel assembly 7, and by having the scraper 12 slide in contact with the track 15, the scraper 12 can remove impurities or hard objects from the surface of the track 15 during the walking process of the walking wheel assembly 7, thereby preventing impurities or hard objects from damaging the track 15 or the walking wheel assembly 7, and preventing the track walking device from bumping, thus making the track walking device run more smoothly.

[0108] By making the position of scraper 12 adjustable, the scraper 12 can be readjusted after wear, so that the scraper 12 can make better contact with the surface of track 15.

[0109] Optionally, the scraper 12 is provided with a waist-shaped groove that extends along the height direction of the track traveling device. A threaded fastener passes through the waist-shaped groove and is threadedly connected to the support base 11 to fix the scraper 12 to the support base 11. By providing a waist-shaped groove on the scraper 12, the position of the scraper 12 can be adjusted along the extension direction of the waist-shaped groove.
