Description

Technical Field

[0001] This utility model relates to the field of transport trestle technology, and in particular to a transverse adjustable track support frame for transport trestle. Background Technology

[0002] The currently used trestle includes a rear step, a connecting bridge body, and a front step. The connecting bridge body includes a left main beam, a right main beam, a front crossbeam, a rear crossbeam, and a connecting beam. A front support leg is installed under the front crossbeam, and the trestle's rear wheel is installed under the rear crossbeam. An intermediate support mechanism is installed under the left and right main beams.

[0003] A search revealed a patent document with publication number "CN209010949U" that discloses an inverted arch trestle bridge (i.e., a transport trestle bridge) capable of automatic travel and correction. The trestle bridge includes a rear step, a connecting bridge body, and a front step. A central support mechanism is located below the connecting bridge body, comprising support frames on both sides and a support plate between the two support frames. A track plate that can move left and right along the support plate is located above the support plate, and a main beam travel track is located above the track plate. A central support leg that can extend and retract vertically is located below the support frames. Lateral adjustment cylinders are installed on the support frames on both sides, with their top rods resting on the lateral ends of the track plate. A rack and pinion track is installed above the left and right main beams along the front-to-back direction, and gears matching the rack and pinion track are installed on the support frames. During travel, the lateral adjustment cylinders can automatically adjust the trestle bridge's direction of travel as needed, reducing labor intensity and accelerating construction progress.

[0004] Based on the above search and combined with existing technology, it was found that the existing transverse adjustment support frame for transport trestle needs to bear a large frictional force between the trestle and the support frame during adjustment. The power required to overcome this frictional force is large, resulting in high energy consumption during adjustment. At the same time, the large frictional force accelerates the wear of the support and the trestle, resulting in a reduced service life. Therefore, there is a need for a transverse adjustment track support frame for transport trestle. Utility Model Content

[0005] The purpose of this application is to provide a lateral adjustable track support frame for a transport trestle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a lateral adjustment track support frame for a transport trestle, comprising a fixed support, a support track fixed to the upper end of the fixed support, a sliding bracket slidably installed on the support track, and a lateral adjustment cylinder for pushing the sliding bracket to slide laterally;

[0007] An electromagnet is detachably installed on the bottom wall of the support track, and a permanent magnet is detachably fixed at the bottom of the sliding bracket. When the electromagnet is energized, it generates a magnetic field that repels the permanent magnet, causing the permanent magnet to rise and levitate. When the permanent magnet is levitated, the sliding bracket and the support track are fitted with a gap.

[0008] The height of the transverse groove supporting the track is greater than the sum of the heights of the electromagnet and the permanent magnet.

[0009] Preferably, the inner wall of the transverse groove of the support track is fixedly embedded with a power-connecting pin that is electrically connected to the electromagnet. The power-connecting pin is electrically connected to an external power source through a wire. A cable box covering the outside of the wire is fixed on the outer side of the support track corresponding to the power-connecting pin.

[0010] Preferably, a mounting base is detachably installed at the bottom of the support rail, the electromagnet is fixedly embedded in the mounting base, and a horizontal through hole is opened on the side of the support rail away from the power connection pin, through which a connecting bolt threaded to one side of the mounting base is inserted.

[0011] Preferably, the top of the mounting base is provided with a mounting groove for embedding the electromagnet, and one side of the mounting base is provided with a connecting screw hole that matches the thread of the connecting bolt.

[0012] The bottom of the mounting base has a vertically extending stepped hole. A limit bolt is inserted into the stepped hole. A limit frame is fixed to the upper end of the limit bolt. The bottom wall of the limit frame abuts against the top of the mounting base and the top of the electromagnet. A limit nut is screwed to the lower end of the limit bolt. The limit nut is rotated and embedded in the lower end of the stepped hole, and the top of the limit nut abuts against the top wall of the stepped hole.

[0013] Preferably, a fixed base is fixed at the bottom of the sliding bracket, and a fixed groove is opened at the bottom of the fixed base for embedding the permanent magnet. A limit box is snapped into the fixed groove. The bottom of the limit box is a frame and abuts against the bottom of the permanent magnet. A fixing bolt with the end screwed to the side wall of the limit box passes through the fixed base.

[0014] Preferably, a slider is integrally formed on the side of the fixed seat near the lateral adjusting cylinder, and a side slide is slidably connected to the slider. The side slide has a vertically extending vertical groove that is adapted to the slider, and the side slide is slidably embedded in the support rail.

[0015] The top of the side slide is slidably fitted with the top of the transverse slide groove of the support rail, the bottom of the side slide is slidably fitted with the top of the limit frame, the two sides of the side slide are slidably fitted with the front and rear sides of the transverse slide groove of the support rail, and the side of the side slide away from the fixed seat is fixed to the end of the piston rod of the transverse adjusting cylinder.

[0016] Preferably, T-shaped fixing frames are also provided at intervals on one side of the fixed support, and the lateral adjusting cylinder is fixedly installed on the T-shaped fixing frame. The lower ends of both the fixed support and the T-shaped fixing frame are fixed to the ground.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. In this utility model, by setting up an electromagnet and a permanent magnet, the electromagnet generates a magnetic field that repels the permanent magnet, causing the permanent magnet to rise and levitate. This allows the sliding bracket to fit with the support track with a clearance. At this time, the sliding bracket can be moved by the lateral adjustment cylinder to achieve the purpose of adjustment. Since the sliding bracket is in a suspended state during adjustment, the energy consumed by the lateral adjustment cylinder is significantly reduced, achieving the effect of energy saving and emission reduction. At the same time, there is no friction between the support track and the sliding bracket, so that both are almost undamaged during use, greatly extending the service life of the lateral adjustment track support frame of the transport trestle and reducing equipment maintenance costs.

[0019] 2. In this utility model, by setting up a mounting base, a limiting frame and connecting bolts, the operator can unscrew the connecting bolts to detach the mounting base from the support rail, and further unscrew the limiting nut to disassemble the limiting frame, thereby removing the electromagnet. This makes it easier to disassemble and maintain the electromagnet when it is damaged and needs to be replaced or other maintenance is required, making maintenance more convenient and faster.

[0020] 3. In this utility model, the permanent magnet can be disassembled and maintained by setting the fixed base and the side slide, which facilitates the replacement or installation of the permanent magnet and is easy to operate. At the same time, although the side slide generates some friction with the support rail or the limiting frame, its friction force is smaller than that of the sliding bracket and the support rail in the prior art. The maintenance cost is lower when friction damage occurs, and it can maintain the balance of the fixed base and meet the lateral sliding requirements of the sliding bracket.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Reference Figures 1-4 The lateral adjustment track support frame for a transport trestle shown includes a fixed support 1, a support track 2 fixed to the upper end of the fixed support 1, a sliding bracket 3 slidably installed on the support track 2, and a lateral adjustment cylinder 4 for pushing the sliding bracket 3 to slide laterally.

[0029] An electromagnet 5 is detachably installed on the inner bottom wall of the support track 2, and a permanent magnet 6 is detachably fixed at the bottom of the sliding bracket 3. When the electromagnet 5 is energized, it generates a magnetic field that repels the permanent magnet 6, causing the permanent magnet 6 to rise and levitate. When the permanent magnet 6 is levitated, the sliding bracket 3 and the support track 2 are fitted with a clearance.

[0030] The height of the transverse groove supporting track 2 is greater than the sum of the heights of electromagnet 5 and permanent magnet 6.

[0031] Based on the above structure, when the trestle needs to be adjusted laterally, the electromagnet 5 is first energized, causing it to generate a magnetic field that repels the permanent magnet 6, thus suspending the permanent magnet 6. This allows the sliding bracket 3 to be in a gap-fitted state with the support rail 2 (i.e., in a separated state, but the sliding bracket 3 is not completely detached from the support rail 2). At this point, the adjustment purpose can be achieved by pushing the sliding bracket 3 with the lateral adjustment cylinder 4. Since the sliding bracket 3 is in a suspended state during adjustment, the energy consumed by the lateral adjustment cylinder 4 is significantly reduced, achieving the effect of energy saving and emission reduction. At the same time, there is no friction between the support rail 2 and the sliding bracket 3, resulting in almost no wear and tear during use. This greatly extends the service life of the lateral adjustment rail support frame of the transport trestle and reduces equipment maintenance costs.

[0032] Furthermore, the inner wall of the transverse slide of the support rail 2 is fixedly embedded with a power pin 22 that is electrically connected to the electromagnet 5. The power pin 22 is electrically connected to an external power source (the external power source can be a commonly used power source in the prior art, such as industrial power, storage battery, etc.) through a wire. The support rail 2 is fixed with a cable box 23 covering the outside of the wire corresponding to the power pin 22.

[0033] In addition, a controller (not shown in the figure) should be provided. The controller can control the on / off of the wires of the power pin 22 and the opening and closing and working direction of the lateral adjustment cylinder 4. The controller can be a commonly used controller in the prior art that is suitable for this embodiment, such as the USR-IO424T programmable logic controller (PLC). Of course, those skilled in the art can also select other models of controllers according to actual usage requirements. This is prior art and will not be elaborated here.

[0034] Furthermore, a mounting base 7 is detachably installed at the bottom of the support rail 2, and the electromagnet 5 is fixedly embedded in the mounting base 7. A through hole 21 is opened on the side of the support rail 2 away from the power pin 22, which is horizontally penetrating the side wall of the support rail 2. A connecting bolt 8 that is threaded to one side of the mounting base 7 is inserted in the through hole 21.

[0035] The top of the mounting base 7 has a mounting groove 72 for the electromagnet 5 to be embedded, and the side of the mounting base 7 has a connecting screw hole 73 that is adapted to the thread of the connecting bolt 8.

[0036] The bottom of the mounting base 7 has a vertically extending stepped hole 74. A limit bolt 711 is inserted into the stepped hole 74. A limit frame 71 is fixed at the upper end of the limit bolt 711. The bottom of the limit frame 71 abuts against the top of the mounting base 7 and the top of the electromagnet 5. A limit nut 712 is screwed to the lower end of the limit bolt 711. The limit nut 712 is rotatably embedded in the lower end of the stepped hole 74, and the top of the limit nut 712 abuts against the inner top wall of the stepped hole 74.

[0037] With the installation base 7, the limiting frame 71 and the connecting bolt 8, the operator can unscrew the connecting bolt 8 to disengage the installation base 7 from the support rail 2, and further unscrew the limiting nut 712 to disassemble the limiting frame 71, thereby removing the electromagnet 5. This makes it easier to disassemble and maintain the electromagnet 5 when it is damaged and needs to be replaced or other maintenance is required, making maintenance more convenient and faster.

[0038] Furthermore, a fixed base 31 is fixed at the bottom of the sliding bracket 3. A fixed groove 312 for the permanent magnet 6 to be embedded is opened at the bottom of the fixed base 31. A limit box 33 is snapped into the fixed groove 312. The bottom of the limit box 33 is a frame and abuts against the bottom of the permanent magnet 6. A fixing bolt 34 with the end screwed to the side wall of the fixed base 31 is provided.

[0039] The fixed base 31 has a slider 311 integrally formed on the side near the horizontal adjustment cylinder 4. A side slide 32 is slidably connected to the slider 311. A vertical slide groove 321 extending vertically and adapted to the slider 311 is opened on the side slide 32. The side slide 32 is slidably embedded in the support rail 2.

[0040] The top of the side slide 32 is slidably attached to the top of the transverse slide groove of the support rail 2, the bottom of the side slide 32 is slidably attached to the top of the limit frame 71, the two sides of the side slide 32 are slidably attached to the front and rear sides of the transverse slide groove of the support rail 2, and the side of the side slide 32 away from the fixed seat 31 is fixed to the end of the piston rod of the transverse adjusting cylinder 4.

[0041] The fixed base 31 and the side slide 32 enable the permanent magnet 6 to be disassembled and maintained, facilitating the replacement or installation of the permanent magnet 6. The operation is convenient. Although the side slide 32 generates some friction with the support rail 2 or the limiting frame 71, its friction is less than that between the sliding bracket 3 and the support rail 2 in the prior art. The maintenance cost is lower when friction damage occurs, and it can maintain the balance of the fixed base 31 to meet the lateral sliding requirements of the sliding bracket 3.

[0042] Furthermore, T-shaped fixing frames 9 are also provided at intervals on one side of the fixed support 1. The horizontal adjustment cylinder 4 is fixedly installed on the T-shaped fixing frame 9. The lower ends of both the fixed support 1 and the T-shaped fixing frame 9 are fixed to the ground. Installing the horizontal adjustment cylinder 4 at intervals on the T-shaped fixing frame 9 is conducive to fixation. Moreover, the sliding bracket 3 can be moved from the side of the support rail 2 for maintenance, making it more convenient to use.

[0043] The working principle of this utility model is as follows: In daily use, the electromagnet 5 is first energized, which generates a magnetic field that repels the permanent magnet 6, causing the permanent magnet 6 to rise and levitate. This allows the sliding bracket 3 to be properly fitted with the support rail 2. Then, the sliding bracket 3 can be moved by the lateral adjustment cylinder 4 to achieve the adjustment purpose. Since the sliding bracket 3 is in a suspended state during adjustment, the energy consumed by the lateral adjustment cylinder 4 is significantly reduced, achieving the effect of energy saving and emission reduction. At the same time, there is no friction between the support rail 2 and the sliding bracket 3, so that there is almost no wear and tear during use, which greatly extends the service life of the lateral adjustment rail support frame of the transport trestle and reduces equipment maintenance costs.

[0044] In addition, the electromagnet 5 and permanent magnet 6 can be easily installed and disassembled, making subsequent maintenance more convenient.

[0045] It should be further noted that the technical features involved in this utility model patent application, such as the power connection pin, the lateral adjustment cylinder, the electromagnet, and the permanent magnet, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
