[0060] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0061] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the accompanying drawings.Where possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0062] In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the specification of the present invention may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0063] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings contained in each term.

[0064] like Figure 1 and Figure 2 As shown, the utility model discloses an anti-overturning device for track arrangement of a walking mechanism, which includes: a frame main body 10, a lifting screw part 20, a support beam part 30, a plurality of wheel guide parts 40 and a plurality of bottom support parts 50. Among them, the support beam part 30 is installed on the upper part of the frame main body 10, and is movably connected with the two side ends of the frame main body 10. The lifting screw part 20 is installed between the support beam part 30 and the frame main body 10, and the support beam part 30 is lifted upward by the lifting screw part 20, so that the support beam part 30 moves up and down along the frame main body 10. The bottom support part 50 and the wheel guide part 40 are installed at the bottom of the frame main body 10, and correspond to each other one by one, and the wheel guide part 40 is located on the inner side of the bottom support part 50.

[0065] like Figure 3 and Figure 4As shown, the frame main body 10 includes a first frame 11, a second frame 12 and a frame crossbeam 13. The first frame 11 and the second frame 12 are arranged relatively parallel, and the frame crossbeam 13 is connected between the first frame 11 and the second frame 12. The upper parts of the first frame 11 and the second frame 12 are hollow frame structures for movably connecting the support beam part 30.

[0066] The main frame part 10 is mainly used to connect the entire anti-overturning mechanism, playing a role of connecting the upper and lower parts. A mounting plane matching the swivel bracket 41 for mounting the wheel guide part 40 is provided at the bottom of the main frame part 10, and is fastened by bolt washers 14. Four support pads are respectively provided at the four corners of the bottom of the main frame part 10, and the axial center of the support pad is processed with a trapezoidal thread. The trapezoidal thread is matched and connected with the support screw 51 of the bottom support part.

[0067] The main body 10 of the frame is provided with two mutually parallel guide cylinders (i.e., hollow frame structures) which cooperate with the first guide rod 32 and the second guide rod 33 of the support beam 30. A row of pin holes are evenly distributed on the frame guide cylinder (i.e., hollow frame structure) and the first guide rod 32 and the second guide rod 33 of the support beam 30. In the process of adjusting up and down, the pin holes with appropriate heights are selected to cooperate, and the pins 15 are used to penetrate and support so that they do not fall down. The left-handed nut 17 is fixed to the mounting hole of the frame by the fastening screw 16 in the middle part of the frame, and the left-handed nut 17 and the left-handed thread of the jacking screw 21 are matched with each other.

[0068] like Figure 5 and Figure 6 As shown, the support beam portion 30 includes a support beam 31, a first guide rod 32 and a second guide rod 33, and the two ends of the support beam 30 are fixedly connected to the upper end of the first guide rod 32 and the upper end of the second guide rod 33 respectively.

[0069] The first guide rod 32 is disposed in the hollow frame structure of the first frame 11 , and the second guide rod 33 is disposed in the hollow frame structure of the second frame 12 , and they are fixed by the latches 15 respectively.

[0070] The main function of the support beam part 30 is to support the bottom of the small flat beam after being connected to the main part of the frame 10 to prevent the walking mechanism from overturning. Two symmetrical step holes are set at both ends of the lower end of the support beam 31, which match the first guide rod 32 and the second guide rod 33 respectively, and are fastened from the upper end of the support beam 31 by bolt washers 14. A mounting hole for a right-handed nut 35 is set in the middle position of the support beam 31, and the right-handed nut 35 is fastened to the lower end of the support beam 31 by bolt washers 14. Two step grooves are symmetrically set at the mounting hole position of the right-handed nut 35 at the lower end of the support beam 31, and a stop block 37 is installed in the step groove and fixedly connected by bolts 36.

[0071] The anti-rotation block 37 is used to prevent the right-handed nut 35 from rotating after being subjected to the rotational force. Since the height difference from the bottom of each small flat beam to the track plane is different, and the small flat beam is a welded structural part, the position of the ribs at the two supporting points at the bottom of the small flat beam is not completely horizontal, and there is a drop phenomenon. Therefore, a pad 39 with a freely combinable thickness is provided between the upper end surface of the supporting crossbeam 31 and the connecting part of the small flat beam to compensate for the gap between the supporting crossbeam 31 and the supporting part at the bottom of the small flat beam, so that the anti-overturning mechanism and the walking mechanism complete the connection support.

[0072] like Figure 7 and Figure 8 As shown, the lifting screw part 20 includes a lifting screw 21 and at least one lifting handle 22. The first end of the lifting screw 21 is connected to the frame crossbeam 13 through a left-handed nut 23, and the second end of the lifting screw 21 is connected to the supporting crossbeam 31 through a right-handed nut 34. The lifting handle 22 is installed in the middle part of the lifting screw 21 and is used to rotate and lift the lifting screw 21.

[0073] Left-handed threads and right-handed threads are arranged on both sides of the jacking screw 21, which are matched and connected with the left-handed nut 17 and the right-handed nut 35 respectively. A mounting threaded hole for the jacking handle 22 is arranged in the middle of the jacking screw 21, and the jacking handle 22 is evenly installed in the middle section of the jacking screw 21. When the operator needs to adjust the height of the supporting beam 31, he only needs to rotate the jacking handle 22 to adjust it.

[0074] like Fig. 9 and Fig.10 As shown, support pads are respectively arranged at the corners of the bottom of the first frame 11 and the second frame 12, and the center position of the support pads is set as a trapezoidal thread. The bottom support part 50 includes a support screw 51, and the support screw 51 is matched and connected with the trapezoidal thread so that the support screw 51 can be adjusted up and down.

[0075] Furthermore, the bottom supporting part 50 further includes a bottom plate 52 , a pin hole 53 is provided at the lower end of the supporting screw rod 51 , and the bottom plate 52 is connected to the pin hole 53 of the supporting screw rod 51 through a cotter pin 54 .

[0076] Furthermore, the bottom support portion 50 further includes a support handle 55 , which is mounted on the top end of the support screw 51 .

[0077] The bottom support part 50 is mainly used for lifting the entire anti-rollover mechanism as a whole when the anti-rollover mechanism is pushed to the target position, separating the walking wheel guide part from the ground, so that the walking wheel and the plane thrust bearing of the walking wheel guide part 40 do not play a supporting role, thereby improving the supporting capacity of the anti-rollover mechanism and improving its stability.

[0078] The support screw 51 matches the trapezoidal thread on the central axis of the bottom support block of the main frame part 10, so as to realize the up and down adjustment of the support screw 51. A support handle 55 is provided at the upper end of the support screw 51 to facilitate the rotation operation of the operator, and a pin hole is provided at the lower end of the support screw 51. After the chassis 52 and the support screw 51 are assembled, the support screw 51 and the chassis 52 are connected by a cotter pin 54. The chassis 52 can effectively increase the bottom support area and make the bottom support more stable.

[0079] like Figures 11 to 14 As shown, the walking wheel guide part 40 includes a walking wheel rotating mechanism 41 and a central axis rotating mechanism 42. The walking wheel rotating mechanism 41 is installed in the central axis rotating mechanism 42 for transferring and supporting the anti-overturning device.

[0080] The wheel guide part 40 is mainly used to transfer and support the entire anti-tipping mechanism, ensuring that the anti-tipping mechanism has a flexible steering function during the transfer process and will not derail or get stuck.

[0081] Preferably, the wheel rotation mechanism 41 includes a rolling body consisting of a wheel 411, a key bar 412 and a wheel shaft 413. A step on one side of the wheel 411 matches with a step on one side of the wheel shaft 413. The other side of the wheel 411 is fixed by a shaft retaining ring 414 to prevent the wheel 411 from moving axially.

[0082] The two ends of the wheel shaft 413 are respectively provided with bearings 415 and bearing seats 416, which are assembled on the bearing seat mounting holes of the wheel bracket 423 and fastened with bolts and washers 418. A bearing baffle 419 is installed on the outer side of the bearings 415 on both sides, and the bearing baffle 419 is fixed to the end faces of both sides of the wheel shaft 413 with bolts and washers 418 to prevent the bearings 415 from moving. The bearing baffles 419 on both sides are respectively provided with threaded holes for mounting grease nipples 43, and the grease nipples 43 are screwed on the bearing baffles 419 through screw washers 431 to ensure that the bearings 415 can be regularly maintained and lubricated.

[0083] More preferably, the central axis rotation mechanism 42 includes a swivel bracket 421, a planar thrust bearing 422 and a walking wheel bracket 423, and the planar thrust bearing 422 is installed on the central axis of the swivel bracket 421, the upper plane of the planar thrust bearing 422 matches the plane of the swivel bracket 421, and the lower plane of the planar thrust bearing 422 matches the bearing mounting hole of the walking wheel bracket 423.

[0084] In the central axis rotation mechanism 42, a planar thrust bearing 422 is provided on the rotating bracket 421 and installed on the central axis of the rotating bracket 421. The upper plane of the planar thrust bearing 422 matches the plane of the rotating bracket 421, and the lower plane of the planar thrust bearing 422 matches the bearing mounting hole of the walking wheel bracket 423.

[0085] The other side is provided with a retaining ring 424 and an axle retaining ring 425, which fix the central axis rotating mechanism and connect it with the upper plane step hole of the running wheel bracket 423. The running wheel guide part is fastened to the bottom mounting plane of the frame main part 10 by bolts 426.

[0086] like Figures 15 to 18 As shown, the use scenario of the anti-overturning device installed on the track of the trolley traveling mechanism, the overturning device 100 is installed between the track 200 and the trolley traveling mechanism 300.

[0087] like Fig.19 and Fig. 20 As shown, the anti-overturning device of the walking mechanism track arrangement is in the limit state after being adjusted up and down by the jacking screw.

[0088] like Figures 21 to 33 As shown in the figure, operators can carry out track installation tasks according to the layout of several major components of the trolley travel mechanism. The specific process is as follows:

[0089] Step 1: When the on-site track assembly operation is used for the first time, the operator will first determine the placement of the anti-overturning device based on the dimensions of the running mechanism assembly drawing. Then use the assembly workshop crane to hoist the running mechanism track assembly anti-overturning device to the top of the track at the track assembly station. Fig.21 shown.

[0090] The wheel component of the anti-overturning device is set with a rim on one side and no rim on the other side. A gap of about 5mm is reserved between the inner side of the rim and the step edge of the track groove. Ensure that the wheel will not get stuck or derail when moving along the track. Fig. 22 shown.

[0091] It is worth noting that the first use of the anti-overturning device requires lifting by a crane, but subsequent use does not require lifting and can be directly pushed to the designated position.

[0092] Step 2: Lift the trolley wheel assembly of the bottom walking mechanism to the installation position, and use the jack to level the trolley components at the bottom of the trolley. The specific operation content does not belong to the invention content item and is not described in detail, such as Fig.23 shown.

[0093] Step 3: As follows Fig.24 As shown, the small flat beam is hoisted to the top of the two trolleys that need to be installed in coordination, and the two dummy shafts 400 are installed into the matching holes of the small flat beam and the trolley in turn. Fig.25 shown.

[0094] Step 4: At this time, the bottom of the balance beam needs to be supported by an anti-tilt device. The operator pushes the anti-tilt device so that it is directly below the balance beam. At this time, rotate the four support screws evenly distributed at the bottom of the anti-tilt device to make the bottom chassis support stable, that is, the chassis support is stressed (such as Fig.26 Ensure that the guide wheel is not stressed (as shown in the N part of the figure). Fig.26 M part), to prevent the bearing components from being subjected to overturning support force, protect the bearings and improve the anti-overturning support capacity of the anti-overturning device, such as Fig.26 shown.

[0095] Step 5: The operator uses the handle of the jacking screw part to rotate the jacking screw to jack up the support beam part (such as Fig. 27 (as shown in the O part in the middle) to the closest distance to the bottom of the small flat beam, and make the pin holes of the guide rod match the pin holes evenly distributed on the guide tube of the main part of the frame. At this time, insert a pin (as shown in the O part in the middle) on both sides. Fig. 27 As shown in the P part, insert the pin part) and rotate the lifting screw in the opposite direction, so that the pin can carry and transmit the supporting force to avoid the thread of the lifting screw being stressed, and protect the thread to prevent deformation due to stress, such as Fig. 27 shown.

[0096] Step 6: Since the upper plane of the support beam is not completely in contact with the bottom of the balance beam, there is a gap between the support beam and the balance beam, such as Fig.28 As shown by arrow E.

[0097] At this time, it is necessary to use the matching combined pad parts, combine the pads to the measured thickness according to the actual measured size, and insert the combined pads between the support beam and the balance beam. Fig.18 As shown, the support points A and B at the bottom of the balance beam are padded with pads. This compensates for the support gap (for example Fig.30 The gap compensation block C) shown in the figure enables the anti-overturning device to support the balance beam. The partial view of the pad usage scenario is as follows Fig.29 shown.

[0098] Step 7: Repeat steps 3, 4, 5 and 6 to complete the assembly of another set of small balance beam trolleys and dummy axles, and support the anti-overturning device in place to eliminate the potential safety hazard of overturning. Fig.30 shown.

[0099] Step 8: As follows Fig.31 As shown, the large balance beam is hoisted above the two small balance beams that need to be assembled, and the two dummy shafts 400 are sequentially installed into the matching holes of the large balance beam and the small balance beam. The assembly work of the track arrangement of the main components of the entire walking mechanism is completed, as shown below Fig.31 shown.

[0100] So far, the walking mechanism track installation anti-overturning device has been applied to the walking mechanism track installation operation site, making the entire installation process safe and reliable.

[0101] In the early stage of the track installation of the walking mechanism, the operators pre-arrange the distribution of the trolley frame according to the design blueprint size layout. The anti-overturning device is moved along the extension direction of the track to between the two trolleys.

[0102] Then, the trolley frame is hoisted to the designated position in turn, and the trolley is horizontally adjusted and supported by a jack or other equipment.

[0103] Then, the small balance beam is lifted by a crane and connected to the trolley frame through a dummy shaft assembly. After the connection is completed, the anti-overturning device corresponding to each small balance beam is moved to a suitable position along the track direction, and the four bottom support legs of the anti-overturning device are fixed to the ground through trapezoidal threads to prevent the wheel guide components from being stressed.

[0104] Then, rotate the jacking screw handle to make the jacking screw part drive the support beam part to move up and down. Since the size and position of the balance beam and the ground are uncontrollable, the support beam can only be lifted to a position close to the bottom of the balance beam, and the pin can be inserted into the matching pin hole of the frame and the guide rod. After inserting the pin, rotate the jacking screw in the opposite direction to remove the force from the thread. At this time, the gap between the balance beam and the support beam is compensated by the adjustment pad prepared in advance, thereby completing the anti-overturning work of the track arrangement of the walking mechanism.

[0105] By utilizing the road surface and side walls on both sides of the track infrastructure, setting up wheel guide parts to facilitate the overall movement and adjustment of the device position, and using other parts in combination, this type of walking mechanism can be made more convenient, quick, safe and stable during assembly and arrangement operations.

[0106] The utility model is a rollover prevention device for the installation of the track of the walking mechanism, which can conveniently, quickly, safely and reliably effectively prevent the rollover hidden dangers existing in the installation process of the track of the walking mechanism.
