Description

Technical Field

[0001] The invention belongs to the technical field of manipulators, and in particular relates to a track plate clamping and turning device and a control system thereof. Background Art

[0002] With the rapid development of high-speed railways, the demand for track plates for high-speed rail has gradually increased, and the current stage has put higher requirements on the production efficiency of track plates. In the current track plate manufacturing process, after the demolding operation is completed, the track plate faces the back. The track plate needs to be flipped 180 degrees to the front side to facilitate subsequent inspection, anchoring, and underwater maintenance. In the existing technology, the four lifting lugs on both sides of the track plate are usually installed with eight bolts. The track plate is then lifted from the demolding vehicle to the flipping area using a hoist. The lifting lug installed on one side of the track plate is then lifted by a crane using a wire rope. As the crane is raised and moved, the track plate is flipped. After the flip is completed, the wire rope needs to be passed through the other two lifting lugs and then lifted to the anchoring area. The above process is complicated and requires a large number of staff. It is not only time-consuming and labor-intensive, but also requires high technical skills from the operators. If the operation is not careful, it can easily lead to the risk of the track plate being bumped or falling. In addition, flipping the track plate after demolding is high in labor and time costs, low efficiency, low safety factor, and difficult to ensure quality.

[0003] Therefore, it is necessary to provide an improved technical solution for the above-mentioned shortcomings of the prior art.

The front portion of the first crossbar corresponds to the front portion of the second crossbar, and spur teeth are provided on opposing surfaces of the front portion and the second crossbar. The motor 6 enables meshing and shifting of the first and second crossbars via gears.

[0087] To facilitate the sliding of the first telescopic arm 1-1 and the second telescopic arm 1-2 within the frame 1, a slide rail 9 is provided on the contact surface between the first and second crossbars within the frame 1, parallel to the length of the frame 1. The slide rail 9 is a plurality of parallel strip-shaped protrusions with built-in rollers. The first and second crossbars are also provided with grooves matching the strip-shaped protrusions. The roller axis must be perpendicular to the length of the slide rail 9. The rollers are used to achieve a sliding connection between the first and second crossbars within the frame 1.

[0088] To restrict movement of the first and second crossbars within the frame 1 when they slide to designated positions, positioning pins 7 are provided on the first and second crossbars. Positioning pins 7 are rod-shaped and perpendicularly connected to the slide rails 9. The location of positioning pins 7 depends on the actual design.

[0089] Specifically, such as Figure 3 As shown, the positioning pin 7 comprises a rod-shaped object. The cross-sectional shape of the rod is not limited and can be triangular, rectangular, or trapezoidal, as long as it can achieve the purpose of limiting the movement of the first and second crossbars on the frame 1. In the embodiment of the present application, the first end of the positioning pin includes a rectangular protrusion parallel to the axis of the rod-shaped object. The first surface of the rectangular protrusion is coplanar with the first surface of the rod-shaped object, and the second surface of the rectangular protrusion extends toward the second surface of the rod-shaped object. The rectangular protrusion partially overlaps with the rod-shaped object, and is fixedly connected in a joint manner. The cross-sectional shape of the first end of the positioning pin is a pattern with a rectangular upper portion and a circular lower portion.

[0090] An external cylindrical buckle is installed on the second end of the locating pin. When the second end of the locating pin passes through the rack 1, the cylindrical buckle is installed on the second end of the locating pin to strengthen the fixing strength of the first crossbar and the second crossbar in the rack 1.

[0091] like Figure 4As shown, positioning holes 1-3 matching the cross-section of the positioning pins are provided on the front and back of the rack 1; and through holes are also provided on the first crossbar and the second crossbar, and the positioning pins 7 pass through the through holes through the positioning holes 1-3, so that the first crossbar and the second crossbar are fixed in the rack 1.

[0092] The first telescopic arm 1-1 and the second telescopic arm 1-2 involved in the present application are considered to constitute a telescopic assembly. The motor 6 drives the gear to rotate and then drives the straight teeth constituting the straight rack in the telescopic assembly, which can perform translational telescopic movement of the first telescopic arm 1-1 and the second telescopic arm 1-2, thereby achieving translation of the frame and thus achieving smooth telescopic movement. The telescopic arm 1-1 and the second telescopic arm 1-2 can slide horizontally on the slide rail 9. At the same time, multiple rollers are provided on the slide rail 9, which can reduce the friction between the telescopic arm 1-1 and the second telescopic arm 1-2 and the slide rail 9 during movement, reduce energy loss, and improve the operating efficiency and service life of each component. When the motor 6 drives the gear to rotate clockwise, it drives the first telescopic arm 1-1 and the second telescopic arm 1-2 to extend outward at the same time. When the gear rotates counterclockwise, it is in a retracted state. In the embodiment of the present application, positioning holes can be set according to different templates. The positioning holes can be regarded as keyhole-shaped. Three positioning holes can be set according to design requirements. The positioning pin is inserted and rotated 90 degrees for positioning. The tail of the positioning pin is clamped on the first crossbar and the second crossbar to prevent the positioning pin from falling off. A sensing device is also provided in the positioning hole. After positioning is completed, the sensing device can automatically control the motor to stop running. Then the positioning pin is installed.

This effectively controls inertia and reduces the impact and wear that may be caused to the components, thereby improving the stability and service life of the entire device and the accuracy of the flipping operation.

[0110] A third clamp is provided at the second end of the third rack on connecting plate 19; a fourth clamp is provided at the second end of the fourth rack on connecting plate 19.

[0140] When the fifth power supply module receives the third stop working instruction or the fourth stop working instruction, it stops working.

[0141] This application relates to a track plate clamping and flipping device and its use method is as follows:

[0142] Step S1: Place the track plate 10 to be flipped in the work area, unlock the safety lock, and allow the operator to enter the platform.

[0143] In step S2, the crane lifts the lifting lug of the frame 1 by means of its lifting hook, and operates the track plate clamping and turning device.

[0144] Step S3, during the operation, the track plate clamping and flipping device is first lifted or lowered by the crane, and positioned by the contact between the positioning rod 8 and the track plate surface to ensure that the first rotating beam 2-1 and the second rotating beam 2-2 are horizontally aligned with the track plate 10.

[0145] Step S4 determines whether the first clamping device 4 - 1 and the second clamping device 4 - 2 are flush with the surface of the track plate 10 . Specifically, when the positioning rod pressure sensor senses contact with the track plate 10 , it sends a feedback signal to the electric crane to stop lowering the frame 1 . Alternatively, the positioning rod pressure sensor sends a feedback signal to a warning light and a warning sound. Upon receiving the feedback signal, the warning light and warning sound turn on, prompting the hoisting device operator to stop lowering the frame 1 .

[0146] In step S5, the first telescopic arm 1-1 and the second telescopic arm 1-2 control the motor 6 through the first power module according to the specifications of the different track plates 10, thereby driving the gear connected to the motor 6 to rotate, and then driving the first telescopic arm 1-1 and the second telescopic arm 1-2 to move horizontally on the track. The movement module determines the movement distance of the first telescopic arm 1-1 and the second telescopic arm 1-2, and determines the telescopic length of the first telescopic arm 1-1 and the second telescopic arm 1-2. When the telescopic length reaches the preset length, that is, corresponding to the length of the track plate 10, the movement feedback module sends a command to the first power module to stop the motor 6 and position it using the positioning pins to achieve precise positioning.

[0147] In step S6, the first clamping device 4-1 and the second clamping device 4-2 clamp the track plate 10. The first angle adjustment module adjusts the first angle between the first clamp 16 and the first rotating beam 2-1, and uses the first angle feedback module to feedback the first angle until the clamping angle that matches the track plate 10 is reached. The second angle adjustment module adjusts the second angle between the second clamp 17 and the first rotating beam 2-1, and uses the second angle feedback module to feedback the second angle until the clamping angle that matches the track plate 10 is reached. The third angle adjustment module adjusts the third angle between the third clamp and the second rotating beam 2-2, and uses the third angle feedback module to feedback the third angle until the clamping angle that matches the track plate 10 is reached. The fourth angle adjustment module adjusts the fourth angle between the fourth clamp and the second rotating beam 2-2, and uses the fourth angle feedback module to feedback the fourth angle until the clamping angle that matches the track plate 10 is reached.

[0148] Specifically, the first angle and the second angle rotate simultaneously, and the third angle and the fourth angle rotate simultaneously. Therefore, in general, only one angle feedback module is required in each clamping device. However, in order to improve the angle accuracy, this application chooses to use two angle feedback modules.

[0149] The first clamp 16 and the second clamp 17 are driven by the third power module, and angle feedback is performed by the first angle feedback module and the second angle feedback module. The third clamp and the fourth clamp are driven by the fifth power module, and angle feedback is performed by the third angle feedback module and the fourth angle feedback module, until the clamping angle of the track plate 10 is reached.

[0150] When the track plate 10 contacts the pressure sensors placed on the first clamp 16, the second clamp 17, the third clamp and the fourth clamp, the pressure sensors simultaneously feed back a first signal to the third power module to stop the rotation of the first fixed gear 5-1, and feed back a first signal to the fifth power module to stop the rotation of the second fixed gear 5-2, so that the track plate 10 is fixed in the first clamping device 4-1 and the second clamping device 4-2.

[0151] In step S7, the pressure sensor simultaneously feeds back a second signal to the second power module to start the first rotary axis motor; and feeds back a second signal to the fourth power module to start the second rotary axis motor to perform the track plate flipping operation.

[0152] The first rotation module adjusts the rotation angle of the first clamping device 4-1, and the second rotation module adjusts the rotation angle of the second clamping device 4-2. The first rotation feedback module feeds back the rotation angle and rotation speed of the first clamping device 4-1 to the second power module; the second rotation feedback module synchronously feeds back the rotation angle and rotation speed of the second clamping device 4-2 to the fourth power module; the flipping process first slowly speeds up, then flips at a constant speed, and finally slowly decelerates, flips at a constant speed to a 90° vertical state, and then slowly flips to a horizontal state, effectively controlling the flipping inertia and reducing the impact and wear that may be caused to the components, thereby improving the stability and service life of the entire device and the accuracy of the flipping operation.

[0153] In step S8, after the track slab is flipped, it is transported to the anchoring area via a crane. Once it reaches the designated location, the third power module activates the first and second clamps 16 and 17 to release their grip on the track slab 10. The fifth power module then simultaneously activates the third and fourth clamps to release their grip on the track slab 10. This completes the track slab flipping and transfer process.

[0154] In step S9, steps S1 to S8 are repeated to perform the next cycle operation on the next track plate 10. That is, steps S1 to S8 are repeated to clamp, flip and transfer the next track plate 10.

[0155] The above connecting plate 19 is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
