Description

Technical Field

[0001] The present invention relates to the field of track beam anchor rod replacement equipment, in particular to an auxiliary tool for replacing track beam anchor rods in a small space and an anchor rod replacement method. Background Art

[0002] As an emerging type of rail transportation system, the straddle-type monorail system is a system in which vehicles travel directly astride a single track beam.

[0003] The track beams are connected to the substructure (base plate) through cast steel tension supports to form a single-track beam bridge system.

[0004] The cast steel tension bearing consists of an upper support, a lower support, and a shear tenon fixed to the cap beam to limit the lower support. The lower support is embedded in the base plate and secured by anchor rods and bolts. The tension bearings of straddle-type monorails are subject to significant forces during long-term operation, which can cause anchor rod fractures, affecting the balance of the track beam and even leading to serious safety accidents.

[0005] The existing methods for replacing damaged or broken anchor rods are mainly as follows: 1) using a lifting machine to directly lift the track beam for replacement; 2) using a jack to lift the track beam to a certain height and then replace the anchor rod.

[0006] The method of using lifting machinery to directly lift the track beam to a certain height and then replacing the anchor rod is suitable for elevated sections.

[0007] The anchor rod replacement operation requires good traffic diversion and protection, and a dedicated person is in charge during the operation; special lifting belts are required for lifting operations; when the anchor rods to be replaced are located in underground sections or stations, they are restricted by the space on top of the track beams, such as the canopy on the top of the station, the top plate of the underground section structure, etc., and lifting operations cannot be performed, making it difficult to complete the replacement operation.

[0008] Direct jacking to a certain height for replacement: Cast steel tension supports use anchor rods connecting the anchor box and track beam, with a net length of 0.97m. If directly jacked up for replacement, the track beam must be lifted high enough to allow for anchor rod removal. A height exceeding 1m poses the risk of the track beam overturning. Furthermore, factors such as the lateral superelevation of the curved beam itself pose a significant risk.

[0009] Therefore, in order to facilitate the replacement of track beam anchor rods, an auxiliary tooling that can assist in achieving the replacement of track beam anchor rods is now needed. Summary of the Invention

[0041] The specific implementation of the present invention will be further explained in detail below by describing the best embodiment with reference to the accompanying drawings.

[0042] An auxiliary tooling for replacing anchor rods of a track beam 7 in a small space comprises a supporting main beam 1; a displacement device is provided on the supporting main beam 1; the displacement device comprises a placing mechanism 2 and a pushing mechanism 5 arranged on the supporting main beam 1; the present invention discloses an auxiliary tooling for replacing anchor rods of a track beam 7 in a small space. The auxiliary tooling disclosed in the present invention can realize the lateral movement of the track beam 7 after it is raised, thereby realizing the subsequent replacement operation of the anchor rod. In addition, the present invention arranges the placing mechanism 2 and the pushing mechanism 5, so that the auxiliary tooling can move the corresponding track beam 7 laterally, and can realize stable lateral movement of the track beam 7 in a small space, thereby facilitating the subsequent anchor rod replacement operation.

[0043] The auxiliary tooling disclosed in the present invention is mainly used for the transverse movement of the track beam 7, so that the track beam 7 moves sideways from just above the anchor rod, which facilitates the subsequent extraction and replacement of the anchor rod.

[0044] In addition, in the present invention, the supporting main beam 1 plays a major bearing role, which facilitates the subsequent longitudinal support and placement of the track beam 7. At the same time, the placement mechanism 2 in the present invention includes a supporting slide 21 arranged on the supporting main beam 1; the setting of the supporting slide 21 facilitates the placement of the track beam 7 on the supporting main beam 1, and the setting of the supporting slide 21 facilitates the lateral movement of the supporting slide 21 on the supporting main beam 1; in addition, the pushing mechanism 5 in the present invention includes a lateral pushing component arranged on the supporting main beam 1; the lateral pushing component can realize the offset of the track beam 7 together with the supporting slide 21, so that the track beam 7 is separated from the anchor rod above the support; and then facilitates the subsequent replacement of the anchor rod.

[0045] Furthermore, in the present invention, the support slide 21 is connected to the support main beam 1 through a slide rail mechanism; the slide rail mechanism includes a slide block 22 arranged on the support main beam 1; a slide groove block 25 is provided at the lower end of the support slide 21, and a slide groove block 25 is provided on both sides of each slide block 22; the support slide 21 is clamped on both sides of the slide block 22 through the slide groove block 25; the setting of the slide rail mechanism facilitates the arrangement of the support slide 21 on the support main beam 1, and at the same time facilitates the subsequent lateral sliding of the support slide 21 on the support main beam 1.

[0046] Furthermore, in the present invention, a limit block 24 is provided at the end of the support slide 21; the limit block 24 plays a good limiting role and can laterally limit the track beam 7 placed on the support slide 21 to avoid lateral tilting of the track beam 7.

[0047] Furthermore, in the present invention, a rubber pad 23 is provided on the support slide 21 ; the provision of the rubber pad 23 plays a good role in isolation and protection, preventing the support slide 21 from causing damage to the track beam 7 .

[0048] Furthermore, the lateral pushing component in the present invention includes a pushing jack 52; the pushing jack 52 is connected to the supporting main beam 1 through a cylinder seat; the pushing jack 52 is arranged parallel to the supporting slide 21; the cylinder seat plays a role of raising the height, which facilitates the raising of the pushing jack 52 and the placement and connection of the pushing jack 52 at the upper end of the supporting main beam 1.

[0049] In addition, as a preference, a reinforcing plate 511 is provided at the end of the supporting main beam, and the side of the reinforcing plate 511 is connected to the supporting main beam. At the same time, the reinforcing plate 511 is arranged on the side of the cylinder seat, and the reinforcing plate 511 is connected to the cylinder seat and the supporting main beam at the same time. The reinforcing plate 511 here plays a very good bridging reinforcement role. In addition, the height of the reinforcing plate 511 is higher than the height of the cylinder seat plus the supporting main beam, that is, the side of the reinforcing plate 511 is set higher than the cylinder seat. Such a setting plays a role of mutual side protection. One is that it can facilitate the arrangement of the jack, and the other is that it is convenient to play a role of lateral protection reinforcement.

[0050] Furthermore, a slope adjustment mechanism 4 is provided under the supporting main beam 1 in the present invention; the setting of the slope adjustment mechanism 4 can realize the adjustment of the inclination degree of the overall layout of the auxiliary tooling, and is convenient for changing according to the structure and inclination of the track beam 7, solving the height difference factor at both ends of the track beam 7 with a large longitudinal slope, and preventing longitudinal slippage and head-diving during the jacking process of the track beam 7; in addition, the slope adjustment mechanism 4 in the present invention includes a plurality of single adjustment blocks 41; by setting different numbers of single adjustment blocks 41, adjustment of inclinations of different heights can be realized, thereby increasing the scope of use of the present invention.

[0051] Furthermore, in the present invention, the supporting main beam 1 is connected to the slope adjustment mechanism 4 through an elevated support mechanism 3; the setting of the elevated support mechanism 3 is mainly used to support the corresponding supporting main beam 1 for processing, and finally realize the support of the track beam 7. In addition, the elevated support mechanism 3 disclosed in the present invention includes a rotating connection part 32; the rotating connection part 32 includes an upper support plate 322 and a lower support plate 321 arranged on the supporting main beam 1, and the upper support plate 322 is connected to the lower support plate 321 through a roller shaft; through the setting of the rotating connection part 32, the supporting main beam 1 has a rotation ability, which can be used to adjust the horizontality of the track beam 7 to prevent the track beam 7 from tilting.

[0052] Furthermore, in the present invention, the elevated support mechanism 3 also includes an adjustable connection part 31; the adjustable connection part 31 includes a threaded sleeve 311 arranged on the supporting main beam 1 and a lifting screw 312 inserted in the threaded sleeve 311; the end of the lifting screw is provided with a screw seat 313; the adjustable connection part 31, through the longitudinal movement of the lifting screw 312 in the threaded sleeve 311, can achieve support for the supporting main beam 1 while also facilitating the horizontal adjustment of the track beam 7 in cooperation with the rotating connection part 32; in addition, in the present invention, a screw seat 313 is provided at the end of the lifting screw 312, and the screw seat 313 plays a basic connection role, which facilitates the top pressure placement of the screw seat 313; at the same time, the setting of the screw seat 213 also facilitates the overall adjustment after the adjustable connection part.

[0053] In addition, in order to avoid interference, the present invention requires that there is no fixed connection between the lifting screw 312 and the screw seat 313; the two are in contact with each other, and there is no connection relationship between the two. In other words, the lifting screw is required to be able to move laterally or swing on the screw seat. The reason for such a design arrangement is that the movement mode of the adjustable connection part is longitudinal, and the movement direction of the rotating connection part is rotation. If both of them are fixedly connected to adjacent parts, mutual interference will occur. In order to avoid such problems, the present invention requires that the lifting screw and the screw seat are not connected to each other.

[0054] In addition, in the present invention, a roller or other mechanism may be provided at the lower end of the lifting screw to avoid interference; of course, in order to simplify the structure, an arc-shaped structural design is selected for the lower end of the lifting screw.

[0055] Furthermore, in the present invention, the elevated support mechanism 3 is connected to the slope adjustment mechanism 4 through the base plate 6; the rotating connection part 32 and the adjustable connection part 31 in the elevated support mechanism 3 are connected through the base plate 6; the setting of the base plate 6 enables good linkage between the rotating connection part 32 and the adjustable connection part 31, and also facilitates the subsequent slope adjustment mechanism 4 to perform a raising operation on the auxiliary tooling on one side of the track.

[0056] A construction method for replacing the anchor rods of the track beam 7 using the auxiliary tooling, the construction method comprising the following steps:

[0057] Step 1: Remove the finger plates on the side and top surfaces of the rail beam 7 in sequence, and remove the nuts on the anchor rods with a wrench;

[0058] Step 2: Place the jack on the pedestal of the track beam 7, and set a rubber pad 23 on the top of the jack so that the top of the jack fits the beam body; the jack is required to lift the beam body until the bottom of the support is higher than the top surface of the anchor rod;

[0059] Step 3: Anchor rod replacement tooling is placed at both ends of the track beam 7. The bottom slope adjustment mechanism 4 is used to adjust the height difference between the two ends of the track beam 7 caused by the longitudinal slope. The height difference caused by the lateral superelevation of the curved section is adjusted through the adjustable connection part 31, so that the track beam 7 is placed horizontally on the support slide 21. Then, the jack in step 2 is removed, so that the track beam 7 falls on the auxiliary tooling.

[0060] Step 4: Install a pushing mechanism 5 on the supporting main beam 1; control the pushing mechanism 5 to move the track beam 7 horizontally to a set position, requiring that after the track beam 7 moves horizontally, the edge of the track beam 7 avoids the projection range of the broken anchor rod;

[0061] Step 5: After step 4 is completed, manually remove the broken anchor rod and install a new one;

[0062] Step 6: Install the pushing mechanism 5 again on the side of the supporting main beam 1 opposite to the pushing mechanism 5 in step 4, then start the pushing mechanism 5 on this side, and push the track beam 7 to its original position by pushing the jack 52; place the beam bottom jack in step 2, lower the track beam 7, install the nut, and tighten the beam body.

[0063] specific;

[0064] The present invention discloses an auxiliary tooling for replacing anchor rods of a track beam 7 in a small space. The adjustment system disclosed in the present invention mainly includes a supporting main beam 1; a displacement device is provided on the supporting main beam 1; the displacement device includes a placement mechanism 2 and a pushing mechanism 5 arranged on the supporting main beam 1; the supporting main beam 1 plays a major bearing role, and a placement mechanism 2 is provided on the supporting main beam 1. The placement mechanism 2 facilitates the placement of the track beam 7. In addition, after the track beam 7 is placed on the placement mechanism 2, the pushing mechanism 5 can be used to push the track beam 7 and the placement mechanism 2 to move laterally, thereby realizing the displacement of the track beam 7, so that it is not directly above the anchor rod, thereby facilitating the subsequent external pull-out and replacement operation of the anchor rod.

[0065] In addition, an elevated support mechanism 3 is provided on the supporting main beam 1; the elevated support mechanism 3 is divided into an adjustable connection part 31 and a rotating connection part 32, and the adjustable connection part 31 and the rotating connection part 32 are distributed at both ends of the supporting main beam 1; the main purpose is to achieve the support elevation of the supporting main beam 1, and at the same time facilitate subsequent fine-tuning to ensure that the track beam 7 is in a horizontal rotation state to prevent the track beam 7 from tipping over.

[0066] Specifically, the adjustable connection part 31 includes a threaded sleeve 311, a lifting screw 312 and a screw seat 313; the adjustable connection part 31 of the present invention is a lifting screw system, that is, a screw system is glued at one end of the supporting main beam 1, and a curved hinge joint is provided at the end to achieve fine-tuning; the screw system is screwed in through a thread to adjust the cross slope to the horizontal and adjust the horizontal superelevation of the curved section; the rotating connection part 32 includes a roller shaft, a lower support plate 321, a lower support reinforcement plate 324, and an upper support plate 322; the roller shaft of the present invention passes through the lower support plate 321 and is connected to the upper support plate 322; the roller shaft of the present invention and the upper support plate 322 and the lower support plate 321 are a detachable connection structure, which is convenient for on-site installation and disassembly.

[0067] In addition, in the present invention, two lower support plates 321 are provided in each rotating connection part 32, and the two lower support plates 321 are arranged relatively parallel, and a lower support reinforcement plate 324 is provided between the two lower support plates 321; similarly, two upper support plates 322 are also provided, and an upper support reinforcement plate 325 is provided between the two upper support plates 322; such an arrangement plays a good role in increasing strength.

[0068] In addition, in order to facilitate the cooperation between the lower support plate 321 and the slope adjustment mechanism 4, a lower support base plate is provided at the lower end of the lower support plate 321, the purpose of implementing an increase in the coupling area between the lower support plate 321 and the slope adjustment mechanism 4.

[0069] In addition, the present invention is provided with a slope adjustment mechanism 4 which can solve the height difference factor at both ends of the track beam 7 with a large longitudinal slope by setting different adjustment blocks, thereby preventing longitudinal slippage and head-diving during the jacking process of the track beam 7.

[0070] In addition, in the present invention, the placement system includes a supporting slide 21, a rubber pad 23 is provided on the supporting slide 21, and a limit block 24 is provided at the end of the supporting slide 21; wherein the rubber pad 23 is in contact with the bottom of the track beam 7, and wedge-shaped rubber blocks of different heights can be set to ensure that the track beam 7 is closely attached on the line with a large slope. At the same time, the rubber pad 23 can increase the friction force of the contact surface with the track beam 7 and protect the concrete at the bottom of the track beam 7.

[0071] The limit stopper 24 can be used to replace the anchor rod of the curved section track beam 7. The stopper can prevent the curved section beam from sliding. It is set on the inner side of the curved section and is closely attached to the side of the beam.

[0072] In addition, in order to facilitate the arrangement and placement of the chute block 25, it is required that the chute block 25 is connected to the supporting main beam 1 through the chute bottom plate; in the present invention, the two chute blocks 25 straddle the slide block 22; this can effectively prevent the chute from being displaced and sliding in different directions.

[0073] In addition, apply lubricating oil on the slide and chute before use to reduce friction.

[0074] The slide block 22 is a long iron block protruding from the surface of the support beam, providing a running track for the slide.

[0075] The supporting main beam 1 is a square hollow component to reduce its own weight. At the same time, in order to meet the rigidity requirements, reinforcement plates 511 are set on both sides.

[0076] The upper support plate 322 and the upper support plate reinforcement plate are connected to the lower support plate 321 through a roller shaft to support the entire main beam and the track beam 7 and other loads.

[0077] The power system consists of a cylinder seat, a jack and an oil pump. The cylinder seat is fixed to the main beam by bolts, and the jack is placed horizontally on the cylinder seat. The oil pump controls the two hydraulic jacks to be used in parallel to provide the thrust required for the horizontal movement of the track beam 7, and the cylinder seat provides the supporting reaction force.

[0078] The use of tooling to replace anchor rods solves the problem of limited top space and inability of lifting machinery to operate, eliminates the safety risk of direct jacking with jacks, and uses its own adjustment system to solve the construction difficulties caused by long longitudinal slopes and small radius curves. The synchronous jacking power system can operate effectively and synchronously, and move the track beam 7 horizontally to achieve the purpose of anchor rod replacement.

[0079] In actual use, the transfer of a section of track beam requires the use of two auxiliary toolings. The two auxiliary toolings are distributed at both ends of the track beam. In actual layout, the auxiliary tooling can be placed on the track beam support or other supporting equipment.

[0086] d. The jack on the oil cylinder seat is arranged on the other side, the track beam 7 is moved to the original position; the beam bottom jack is arranged, the track beam 7 is lowered, the nut is installed, and the beam body is fastened.
