Abstract
Description
Technical Field
[0001] This utility model relates to the field of slide rail technology, and in particular to a slide rail for bridge construction. Background Technology
[0002] Bridge construction guide rails are devices used during bridge construction to support and guide the movement of construction equipment or materials along a predetermined path. A guide rail typically consists of two parallel tracks, with transport vehicles or other construction equipment slidably connected to their tops, allowing the vehicles or equipment to glide quickly along the guide rails.
[0003] Chinese utility model patent with announcement number CN222390270U discloses a sliding rail for bridge construction, including a guide rail one, a guide rail two, and a cleaning device. The guide rail two is located on one side of the guide rail one. A sliding seat is provided on the surface of the guide rail one. The cleaning device is provided on the surface of the guide rail one. The cleaning device includes a control block. Multiple cavities are opened on the surface of the guide rail one. The control block is slidably connected to the inner wall of the cavity. An air pressure plate is fixedly connected to one side surface of the control block.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the slide rail is equipped with a cleaning device, which includes multiple control blocks set on the guide rail, and the surface of the guide rail has multiple cavities. The control blocks are slidably connected to the inner walls of the cavities. The above structure increases the unevenness of the top of the guide rail, provides a dead angle for cleaning debris such as gravel and sand, and increases the probability that the sliding seat will be obstructed during its movement along the guide rail. Utility Model Content
[0005] To solve the above problems, this utility model provides a sliding rail for bridge construction.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a slide rail for bridge construction, comprising a slide rail, a sliding seat disposed on the top of the slide rail, and a plurality of rolling wheels rotatably mounted between two seats on both sides of the sliding seat and rolledly connected to the top of the slide rail. L-shaped connecting rods are fixed to the bottom of the seats on both sides of the sliding seat, and a rotating wheel is rotatably connected to the horizontal section of each L-shaped connecting rod. Strip-shaped grooves for the rotating wheels to roll are provided on the side walls of both sides of the slide rail. A cleaning mechanism for cleaning the top of the slide rail is provided on the sliding seat, and the cleaning mechanism includes cleaning components. The cleaning assembly includes a fixed block fixedly installed on the side wall of the sliding seat. Two fixed blocks are provided and symmetrically distributed on both sides of the slide rail. The cleaning assembly also includes a crossbar fixed between the two fixed blocks, a reciprocating screw rotatably installed between the two fixed blocks, a sliding block slidably sleeved on the crossbar, a movable part set on the top of the sliding block and cooperating with the helical groove of the reciprocating screw, and a cleaning brush set on the bottom of the sliding block and pressed against the top of the slide rail. The cleaning mechanism also includes a driving part for driving the reciprocating screw to rotate and a transmission assembly for driving the sliding seat to slide along the slide rail when the reciprocating screw rotates.
[0007] By adopting the above technical solution, during use, the drive component drives the reciprocating screw to rotate, and the transmission component drives the sliding seat to slide along the slide rail. Due to the engagement of the movable component with the helical groove on the reciprocating screw, the circumferential movement of the sliding block is restricted by the crossbar. This allows the sliding block to reciprocate along the axial direction of the reciprocating screw under the action of the movable component, thereby enabling the cleaning brush to repeatedly clean the debris on the slide rail surface. This reduces the probability that the sliding seat will be obstructed by gravel, sand, and other debris falling on the top of the slide rail during its movement along the guide rail. There are no dead corners for cleaning the top of the slide rail, which enhances the cleaning effect on the top of the slide rail and ensures the normal movement of the sliding seat.
[0008] Furthermore, the central shafts at both ends of the reciprocating lead screw pass through two fixed blocks and are rotatably connected. The driving component is a drive motor fixed on the fixed blocks, and the output end of the drive motor is fixed to one end of the reciprocating lead screw.
[0009] By adopting the above technical solution, when it is necessary to control the sliding seat to slide along the slide rail, the operator only needs to start the drive motor and drive the reciprocating screw to rotate. The reciprocating screw drives the moving parts, sliding block and cleaning brush to clean the debris on the top of the slide rail.
[0010] Furthermore, the transmission assembly includes a driving bevel gear fixed to the end of the central shaft of the reciprocating lead screw, a rotating rod rotatably mounted on the bottom of the sliding seat, a driven bevel gear fixedly sleeved on the rotating rod and meshing with the driving bevel gear, and a transmission gear fixed to the lower end of the rotating rod. A rack meshing with the transmission gear is fixed on the side wall of one side of the slide rail, and the length direction of the rack is parallel to the length direction of the slide rail.
[0011] By adopting the above technical solution, when the drive motor drives the reciprocating screw to rotate, the reciprocating screw drives the active bevel gear fixed to its central shaft end to rotate, thereby causing the driven bevel gear meshing with the active bevel gear, the rotating rod fixed to the driven bevel gear, and the transmission gear fixed to the rotating rod to rotate. This causes the transmission gear to move along the rack on one side of the slide rail, thereby driving the entire sliding seat to slide along the slide rail. The rotating wheel at the bottom of the sliding seat reduces the friction between it and the slide rail.
[0012] Furthermore, a conical sleeve is fixed to the top of the transmission gear, the top opening diameter of the conical sleeve is smaller than the bottom opening diameter of the conical sleeve, and the bottom of the conical sleeve is located near the edge of the transmission gear.
[0013] By adopting the above technical solution, when the cleaning brush reciprocates to clean the debris on the surface of the slide rail, some of the debris on the top of the slide rail may fall to the top of the transmission gear. The conical sleeve prevents the debris from falling and getting stuck on the transmission gear.
[0014] Furthermore, a clearance ramp is provided at the position corresponding to the tapered sleeve of the slide rail.
[0015] By adopting the above technical solution, when the transmission gear rotates, the transmission gear moves along the rack it meshes with, and the conical sleeve moves synchronously with the transmission gear. The clearance slope on the slide rail plays a clearance role for the conical sleeve, ensuring the smoothness of the sliding seat during movement.
[0016] Furthermore, the width of the bottom wall of the strip-shaped groove is 1-2 cm.
[0017] By adopting the above technical solution, when the cleaning brush reciprocates to clean the debris on the surface of the slide rail, the debris may fall to the perimeter of the slide rail. Since the width of the inner bottom wall of the strip groove is relatively narrow, the debris is not easy to accumulate on the inner bottom wall of the strip groove, thus reducing the efficiency of the rotating wheel being obstructed during its rolling process.
[0018] Furthermore, an inclined surface is provided at the intersection of the bottom wall of the strip groove and the side wall of the slide rail near its bottom, and the distance between the inclined surfaces and the middle of the slide rail increases from top to bottom.
[0019] By adopting the above technical solution, when the cleaning brush repeatedly cleans the debris on the surface of the slide rail, the debris that falls around the slide rail rolls down the inclined surface to the ground, reducing the frequency of cleaning the slide rail by the staff.
[0020] Furthermore, the cleaning mechanism is provided in two sets and is distributed in a mirror image about the sliding seat.
[0021] By adopting the above technical solution, when the sliding seat slides along the slide rail, the cleaning mechanisms on both sides of the sliding seat clean the top of the guide rails on both sides of the sliding seat, thereby enhancing the cleaning effect.
[0022] In summary, this utility model has the following beneficial effects: During use, the driving component drives the reciprocating screw to rotate, and the transmission component drives the sliding seat to slide along the slide rail. Due to the cooperation between the moving part and the helical groove on the reciprocating screw, the circumferential movement of the sliding block is restricted by the crossbar, thereby causing the sliding block to reciprocate along the axial direction of the reciprocating screw under the action of the moving part. This allows the cleaning brush to reciprocate to clean the debris on the surface of the slide rail, reducing the probability that the sliding seat will be obstructed by gravel, sand, and other debris falling on the top of the slide rail during its movement along the guide rail. There are no dead corners for cleaning the top of the slide rail, which enhances the cleaning effect on the top of the slide rail and ensures the normal movement of the sliding seat.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] like Figure 1-6 As shown in the figure, this application discloses a slide rail for bridge construction, including a slide rail 1, a sliding seat 2, and a cleaning mechanism 3. Strip-shaped grooves 11 are provided on both sides of the slide rail 1. An inclined surface 13 is provided at the intersection of the inner bottom wall of the strip-shaped groove 11 and the side wall of the slide rail 1 near its bottom. The distance between the inclined surfaces 13 and the middle of the slide rail 1 increases from top to bottom, causing debris falling around the slide rail 1 to roll down along the inclined surfaces 13 to the ground, facilitating subsequent cleaning work by the workers.
[0032] The sliding seat 2 is located on top of the slide rail 1. Multiple rolling wheels 21 are rotatably mounted between the seat bodies on both sides of the sliding seat 2, and the multiple rolling wheels 21 are rotatably connected to the top of the slide rail 1. L-shaped connecting rods 22 are fixed to the bottom of the seat bodies on both sides of the sliding seat 2. A rotating wheel 23 is rotatably connected to the horizontal section of each L-shaped connecting rod 22. The rotating wheel 23 is rotatably connected to the strip groove 11. The bottom of the rotating wheel 23 near the middle of the slide rail 1 abuts against the inner bottom wall of the strip groove 11. The rotating wheel 23 and the rolling wheels 21 cooperate with each other to reduce the friction of the sliding seat 2 and enhance the smoothness of the sliding seat 2 sliding along the slide rail 1.
[0033] The cleaning mechanism 3 is mounted on the sliding seat 2 and is used to clean the top of the slide rail 1. The cleaning mechanism 3 includes a cleaning component 31, a driving component 33, and a transmission component 32. The cleaning component 31 includes a fixed block 311, a crossbar 312, a reciprocating screw 313, a sliding block 314, a moving component 315, and a cleaning brush 316. The fixed block 311 is fixedly installed on the side wall of the sliding seat 2. There are two fixed blocks 311, which are symmetrically distributed on both sides of the slide rail 1. The crossbar 312 is fixed between the two fixed blocks 311. The crossbar 312 has a circular cross section, and its axial direction is perpendicular to the length direction of the slide rail 1. There are two crossbars 312. The reciprocating screw 313 is rotatably mounted between the two fixed blocks 311. The central shafts at both ends of the reciprocating screw 313 pass through the two fixed blocks 311 and are rotatably connected. The reciprocating screw 313 is parallel to the crossbar 312. The sliding block 314 is fitted onto the crossbar 312 and slides within it. The circumferential movement of the sliding block 314 is restricted by the two crossbars 312. The movable part 315 is located on the top of the sliding block 314 and engages with the helical groove of the reciprocating screw 313, thereby causing the sliding block 314 to reciprocate along the axial direction of the reciprocating screw 313 under the action of the movable part 315. The cleaning brush 316 is located at the bottom of the sliding block 314. The bristles of the cleaning brush 316 abut against the top of the slide rail 1. The cleaning brush 316 reciprocates to clean the debris on the surface of the slide rail 1, reducing the probability of the sliding seat 2 being obstructed during its movement along the guide rail and ensuring the normal sliding of the sliding seat 2.
[0034] The driving component 33 is used to drive the reciprocating lead screw 313 to rotate. The driving component 33 is a drive motor 331 fixed on the fixed block 311. The output end of the drive motor 331 is fixed to one end of the reciprocating lead screw 313. After the drive motor 331 works, it drives the reciprocating lead screw 313 to rotate. The reciprocating lead screw 313 causes the sliding block 314 to move back and forth along the reciprocating lead screw 313, thereby enabling the cleaning brush 316 to clean the debris on the top of the slide rail 1 and reduce the probability of the sliding seat 2 being obstructed during its movement along the guide rail.
[0035] The transmission assembly 32 drives the sliding seat 2 to slide along the slide rail 1 during the rotation of the reciprocating screw 313. The transmission assembly 32 includes a driving bevel gear 321, a rotating rod 323, a driven bevel gear 322, a transmission gear 324, and a rack 325. The driving bevel gear 321 is fixed to the end of the central shaft of the reciprocating screw 313, and the axis of the driving bevel gear 321 coincides with the axis of the reciprocating screw 313. The rotating rod 323 is rotatably mounted on the bottom of the sliding seat 2, and the axis of the rotating rod 323 is perpendicular to the axis of the driving bevel gear 321. The driven bevel gear 322 is fixedly sleeved on the rotating rod 323 and meshes with the driving bevel gear 321, and the axis of the driven bevel gear 322 coincides with the axis of the rotating rod 323. The transmission gear 324 is fixed to the lower end of the rotating rod 323, and the transmission gear 324 and the driven bevel gear 322 move synchronously with the rotating rod 323, and the axis of the transmission gear 324 coincides with the axis of the driven bevel gear 322. The rack 325 is fixed to the side wall of the slide rail 1 and meshes with the transmission gear 324. The length direction of the rack 325 is parallel to the length direction of the slide rail 1. After the drive motor 331 starts working, it drives the reciprocating screw 313 to rotate. The reciprocating screw 313 drives the driving bevel gear 321 to move. The driving bevel gear 321 drives the driven bevel gear 322, which meshes with it, the rotating rod 323 fixed to the driven bevel gear 322, and the transmission gear 324 fixed to the rotating rod 323 to rotate. This causes the transmission gear 324 to move along the rack 325 on one side of the slide rail 1, thereby driving the entire sliding seat 2 to slide along the slide rail 1.
[0036] To prevent debris from falling onto the transmission gear 324 after the cleaning brush 316 reciprocates cleaning the surface of the slide rail 1, a conical sleeve 4 is fixed to the top of the transmission gear 324 and fitted onto the outside of the rotating rod 323. The top opening diameter of the conical sleeve 4 is smaller than the bottom opening diameter, the axis of the top of the conical sleeve 4 coincides with the axis of the bottom of the conical sleeve 4, and the bottom of the conical sleeve 4 is positioned near the edge of the transmission gear 324, effectively preventing debris from falling and remaining on the top of the transmission gear 324. A clearance slope 12 is provided at the position corresponding to the slide rail 1 on the conical sleeve 4. When the conical sleeve 4 moves synchronously with the transmission gear 324, the clearance slope 12 on the slide rail 1 provides clearance for the conical sleeve 4, ensuring the smooth movement of the sliding seat 2.
[0037] To prevent debris from falling onto the inner bottom wall of the groove 11 after cleaning and causing debris accumulation that would affect the rolling effect of the rotating wheel 23, the width of the inner bottom wall of the groove 11 is 1-2 cm, which to some extent reduces the efficiency of the rotating wheel 23 during rolling. In this embodiment, the cleaning mechanism 3 is provided with two sets of mirror images of the sliding seat 2, which can enhance the cleaning effect on the top of the slide rail 1, ensure that there are no dead corners on the top of the slide rail 1, and ensure the normal sliding of the sliding seat 2.
[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
