Description

Technical Field

[0001] The present invention relates to the technical field of rail drilling, and in particular to a high-speed railway rail drilling device based on a precision measurement network. Background Art

[0002] Rail drilling machines are essential small tools used for railway maintenance and repair, playing a crucial role in rail laying. They are categorized into two types: engineering and electrical. Power sources include AC electric, internal combustion, hydraulic, and lithium-ion batteries. Existing models all consist of a powertrain, reduction gearbox, feed system, clamping system, cooling, and other auxiliary components. Power is transmitted to the reduction gearbox, whose output gear drives the drill bit. The entire system is secured to the rail by a clamping system.

[0003] When using existing drilling equipment, most of them require manual labor to lift the drilling machine and install it on the track for drilling, which makes it extremely physically demanding when multiple holes need to be drilled on a section of road. At the same time, since it is too cumbersome to install the drilling machine on the track and it needs to use other equipment for auxiliary positioning, the drilling equipment is too cumbersome. In some cases, when it is necessary to drill the same point on two rails, it is necessary to manually operate the drilling equipment repeatedly, which wastes physical strength and the control accuracy of the point is also easily affected. At the same time, since the drilling equipment needs to manually control the feed rate of the drilling machine when drilling, the operator repeatedly moves and installs the drilling machine, and the feed rate of the drilling machine cannot be accurately controlled after exhaustion, which makes the drilling equipment easily damaged and easily increases the wear of the drill bit. Based on the shortcomings of the existing technology, the present invention designs a high-speed railway rail drilling equipment based on a precision measurement network. Summary of the Invention

[0016] The present invention has the following beneficial effects:

[0017] 1. This high-speed railway rail drilling equipment based on the precision measurement network is designed to disengage the clamping block by stepping down the rear end of the clamping plate with the foot, and then the linkage pedal is stepped down with the heel to rotate it. The linkage pedal drives the left and right auxiliary pedals to move, so that the vertical hinge blocks on the lower surfaces of the two push the linkage arm to move forward. Since the front end of the linkage arm is fixedly connected to the horizontal hinge block, and the horizontal hinge block is hinged to the transmission arm, when the linkage arm moves forward, it drives the fan gear to rotate through the horizontal hinge block and the transmission arm. When the fan gear rotates, the active gear meshing with it The gear wheel is then driven by the gear mechanism to move outward, and the gear mechanism then moves outward, thereby completing the bidirectional drilling and unidirectional drilling of the rails. If unidirectional drilling is required, the user only needs to skip stepping on the card plate to unlock the card block and directly step on the right auxiliary pedal in the required direction. This device is convenient for bidirectional drilling and unidirectional drilling of the rails.

[0018] 2. This kind of high-speed railway rail drilling equipment based on the precision measurement network is to press the control pedal downward with the foot when the precision measurement network rail car and the drilling mechanism move to the area to be drilled. The downward control pedal pushes the inclined connecting long plate downward under the limit of the fixed arm to keep it in a horizontal state. In the process of the connecting long plate tending to be horizontal, it pushes the fixed arm to rotate under the limit of the side hinge block. The rotating fixed arm pushes the first fixed small arm and the second fixed small arm to contact the inner side of the rail. At this stage, the connecting long plate is still in the process of moving. At this time, the first fixed small arm and the second fixed small arm are continuously squeezed by the fixed arm The two sides expand until the anti-skid teeth on the first fixed arm and the second fixed arm contact the rail head and the inner side of the rail bottom of the rail and are limited and clamped, thereby completing the limit fixation of the entire device. After the drilling mechanism completes drilling, the control pedal is released, and the return spring will pull the connecting plate to gradually fit the bottom surface of the precision measuring network rail car. The moving connecting plate will move the control pedal upward through the limit sliding column and the slide groove, so that the control pedal drives the first fixed arm and the second fixed arm to detach from the rail through the connecting long plate and the fixed arm, and the precision measuring network rail car can be moved. This device is convenient for fixing the entire equipment to prevent movement before drilling.

[0019] 3. This high-speed railway rail drilling equipment based on the precision measurement network is achieved by parking the precision measurement network rail car in the rail drilling area, and stepping down the control pedal with the foot to fix the entire equipment. When the control pedal moves down to fix the fixing mechanism, the control pedal will also drive the connecting arm to move down, so that the drilling box moves in an arc under the push of the connecting arm and the limit of the connecting curved arm until it reaches the drilling area. This device facilitates the simultaneous movement of the fixing mechanism and the drilling mechanism to work when the control pedal is stepped on. BRIEF DESCRIPTION OF THE DRAWINGS

Since the front end of the linkage arm 414 is fixedly connected to the horizontal hinge block 415, and the horizontal hinge block 415 is hinged to the transmission arm 516, the linkage When the movable arm 414 moves forward, the sector gear 515 is driven to rotate through the horizontal hinge block 415 and the transmission arm 516. When the sector gear 515 rotates, the driving gear 514 meshing with it rotates accordingly and drives the transmission gear 512 to rotate through the linkage shaft 513. After the transmission gear 512 rotates, it drives the gear plate 510 to move outward through the reduction gear set 511. Since the gear plate 510 is fixedly connected to the upper surface of the drilling motor 507, the movable gear plate 510 drives the drilling motor 507 to move outward. After starting the drilling motor 507, the drilling motor 507 that moves will drive the transmission shaft 508 and the drilling head 509 to move outward and open the hole in the rail, thus completing the bidirectional drilling. If unidirectional drilling is required, it is only necessary to skip stepping on the card plate 410 to unlock the card block 412 and directly step on the right auxiliary pedal 403 in the required direction. This device is convenient for bidirectional drilling and unidirectional drilling of the rail.

[0043] When it is necessary to fix the entire equipment to prevent it from moving before drilling, first, when the precision measuring network rail car 1 and the drilling mechanism 5 move to the area to be drilled, step down the control pedal 2 with your foot. The downward control pedal 2 pushes the inclined connecting long plate 307 downward under the limit of the fixed arm 302 to keep it in a horizontal state. In the process of the connecting long plate 307 tending to be horizontal, it pushes the fixed arm 302 to rotate under the limit of the side hinge block 301. The rotating fixed arm 302 pushes the first fixed small arm 304 and the second fixed small arm 305 to contact the inner side of the rail. At this stage, the connecting long plate 307 is still in the process of moving. At this time, the first fixed small arm 304 and the second fixed small arm 305 on both sides are continuously squeezed by the fixed arm 302. The cam 204 is moved upwards by the limit traction of the control pedal 206 and the limit traction of the limit slide 205 and the slide groove 202, so that the control pedal 2 drives the first fixed arm 304 and the second fixed arm 305 to detach from the rail through the connecting long plate 307 and the fixed arm 302, and the precision measurement network rail car 1 can be moved. This device is convenient for fixing the entire equipment to prevent movement before drilling.
