In order to guarantee the drawing of patterns precision, do not need in advance to take off under the condition of side form, the end mould in the mould, current drawing of patterns mode adopts fixed mechanical jacking shedder, is about to bury the bottom of a plurality of jacks in the ground underground, through controlling the synchronous jacking of a plurality of jacks, its synchronous jacking precision is higher, does not need to open in advance that side form, the end mould on the vertical face of track board also can carry out the drawing of patterns smoothly. However, this method has the following problems: in order to avoid the interference between the jack and a logistics vehicle for transporting the mold, when the jack is initially designed, the initial height of the jack (namely the height when the jack is completely contracted) does not exceed the ground, so that the jack needs to be installed in a pit type sinking mode for fixing, when the jack is used for jacking and demolding, the extending stroke of a piston of the jack needs to be larger than the sum of the heights of the logistics vehicle and the mold to push the track plate out of the mold, and therefore the piston stroke of the jack is required to be very large when the mold is demolded. When the track slab is demolded, in order to ensure the demolding precision of the track slab, a piston rod of a demolding oil cylinder needs to be slowly and synchronously jacked, and because the piston stroke of the demolding oil cylinder is long, long jacking time and low efficiency are caused in a long distance, so that the demolding time is difficult to meet the requirement of production takt, or a demolding station becomes the key time for restricting the takt of a production line. In addition, shedder adopts the design of formula of sinking, and the stroke of jack is great and the size of track board is great and then lead to sinking the ground construction engineering volume great, and the stroke of jack is great in addition, leads to the big and pump station power height of size of hydro-cylinder, causes construction cost and equipment cost higher.
Based on the above description, referring to fig. 1, 4 and 5, an embodiment of the present invention provides a mobile automatic demolding vehicle, including a vehicle body 5, a jacking cylinder 51 and support wheels 52, where the bottom of the vehicle body 5 is provided with rail wheels 53, the rail wheels 53 are adapted to run on a jacking track 4, a plurality of jacking cylinders 51 are provided on the vehicle body 5, the jacking cylinder 51 is adapted to be lifted upwards to eject a track plate 6 located at a demolding station from a mold 3, a plurality of support wheels 52 are provided at the bottom of the vehicle body 5, an axial direction of the support wheels 52 is parallel to an axial direction of the rail wheels 53, when the vehicle body 5 runs to the demolding station, the plurality of support wheels 52 are respectively placed on a plurality of support structures 71 located on a foundation, a length of the support structures 71 is greater than or equal to a diameter of the support wheels 52, and a length of the support structures 71 is less than a length of two adjacent support wheels 52 in a forward direction of the vehicle body 5 The distance between them.
It can be understood that, because the concrete foundation construction precision is lower, there will be height error, height error is usually between 5mm to 10mm, and the jacking track is as the guiding mechanism that the rail wheel that provides the automobile body walked, usually longer, under these two factors, lay on the concrete foundation for the rail that the drawing of patterns car (being automobile body 5) provided the direction, and there is the clearance with the foundation, therefore when the drawing of patterns car was in the jacking, the track had the risk that takes place to subside because of bearing the reaction force that the drawing of patterns car was jacked, make the vehicle take place the skew and install on the plane of co-altitude with the jacking hydro-cylinder of installing on the car, cause jack jacking height inconsistent, influence drawing of patterns precision.
In this embodiment, after the maintained track slab 6 and the mold 3 are conveyed to the demolding station along the track 1, the lifting cylinder on the track car retracts, the track slab 6 and the mold 3 are placed on the positioning seats 2, the mold 3 is positioned and fixed by the positioning seats 2, and then the track slab can be withdrawn, namely, the track slab and the mold 3 are far away from the demolding station, and the track slab and the mold can be returned to the previous station. After the logistics vehicle exits the demolding station, the vehicle body 5 moves from the parking station to the demolding station on the jacking rail 4, then the jacking cylinders 51 synchronously extend upwards to jack the rail plate 6 from the mold 3, demolding is achieved, finally lifting lugs can be installed on the rail plate 6 manually, and the rail plate 6 is lifted to a water culture pond for maintenance through operation of the truss crane.
Through being fixed in on automobile body 5 jacking cylinder 51, when commodity circulation car transportation track board to drawing of patterns station, automobile body 5 can stop to the parking station department of keeping away from the drawing of patterns station, the commodity circulation car transfers mould 3 to drawing of patterns station and withdraws from the back, automobile body 5 passes through rail wheel 53 and goes to the drawing of patterns station, two cars handing-over operation, the automatic production line flowing water beat has fully been satisfied, the interference problem of drawing of patterns station with the commodity circulation car has been avoided, and simultaneously, jacking cylinder 51 need not bury underground below the ground, thereby the stroke of jacking cylinder 51's piston rod has been reduced, the drawing of patterns time has been shortened, and then the production line beat has been shortened, the drawing of patterns efficiency has been improved, also made things convenient for jacking cylinder 51's installation. When the vehicle body 5 stops at the demolding station, the plurality of supporting wheels 52 are respectively supported on the corresponding supporting structures 71, so that the rigid support of the vehicle body 5 and the supporting structures 71 is indirectly realized when the vehicle body 5 is at the demolding station, the precise attachment can be realized through the bolt connection of the supporting structures 71 and the foundation, the rigid support of the vehicle body 5 and the foundation is further realized, meanwhile, the contact area of the vehicle body 5 and the foundation is indirectly increased through the supporting structures 71, the condition that the jacking track 4 and the foundation are settled under the reaction force of the jacking oil cylinders 51 of the vehicle body 5 is avoided, the foundation is even settled, the jacking oil cylinders 51 are always at the same height, the demolding precision is ensured, namely, under the condition that the side molds and the end molds in the mold are not removed in advance, the elastic deformation of the vehicle body 5 under the reaction force of the jacking oil cylinders 51 is avoided under the action of the supporting wheels 52 and the supporting structures 71 of the utility model, therefore, the jacking oil cylinders 51 are always kept at the same height, the track plate 6 cannot interfere with a side mold and an end mold in the mold 3, and the quality problems of peel falling, corner falling, damage, cracks and the like of the demolded track plate 6 are avoided.
It can be understood that, by providing a plurality of supporting structures 71 at the demolding station, since the supporting structures 71 only contact with the supporting wheels 52 when the vehicle body 5 stops at the demolding station, the supporting structures 71 are short compared to the lifting rails 4, and the length of the supporting structures 71 only needs to be capable of supporting the corresponding supporting wheels 52 when the vehicle body 5 is at the demolding station, for example, the length of the supporting structures is equal to the diameter of the supporting wheels, and the area of the foundation occupied by each supporting structure 71 is small, so that each supporting structure 71 can easily make rigid contact with the foundation, unlike the gap existing between the lifting rails 4 and the foundation, and thus, the lifting rails 4 are not settled by the rigid contact between the supporting wheels 52 and the supporting structures 71 when the vehicle body 5 is at the demolding station.
Alternatively, the plurality of support wheels 52 are respectively disposed at positions adjacent to the plurality of lift cylinders 51 in the horizontal direction, or the plurality of support wheels 52 are respectively disposed right below the plurality of lift cylinders 51.
Here, the jacking cylinder sets up on automobile body 5, and under jacking force counteraction, small elastic deformation can take place for the automobile body structure, and because of the required precision of jacking drawing of patterns is higher, elastic deformation also can cause jacking cylinder 51 jacking height to have the deviation, and then probably appear 6 card of track board and die the phenomenon in mould 3 or ejecting quality problems such as 6 lacking edges, falling the angle that cause of carrying out by force of track board. Based on this, this embodiment sets up supporting wheel 52 in jacking cylinder 51 under or the horizontal direction on the adjacent one side position of jacking cylinder, directly transmits downwards under the reaction that receives jacking cylinder 51 for bearing structure 71, and then transmits for the ground, has avoided automobile body 5 to take place elastic deformation and influence drawing of patterns precision because of anti-jacking cylinder reaction force down.
Referring to fig. 4 and 5, alternatively, the number of the support wheels 52 is four, and in the advancing direction (X-axis direction) of the vehicle body 5, the bottom heights of the two support wheels 52 on the front side are higher than the bottom heights of the two support wheels 52 on the rear side, and the top heights of the two support structures 71 on the front side are higher than the top heights of the two support structures 71 on the rear side.
Here, the support wheels 52 are provided with at least four, and the four support wheels 52 are arranged two in front and two in back to form a rectangular support surface for stable support.
Here, it is desirable that the bottom end of each support wheel 52 be of uniform height and the top end of each support structure 71 be of uniform height so that when the support wheels 52 are in rigid contact with the support structures 71, either forward (positive X-axis) or backward (negative X-axis) any one support wheel 52 is not obstructed by any one support structure 71.
However, in order to stabilize the supporting wheels 52, the components related to the supporting wheels 52 are welded and fixed during fixing, or other fixing methods have a problem of installation accuracy, and it is difficult to ensure that the bottom heights of the supporting wheels 52 are consistent, and in the case that the bottom heights of the supporting wheels 52 are not consistent, if the top portions of the supporting structures 71 are set to be the same height, a problem of movement interference occurs, and a problem that individual or all supporting wheels 52 cannot be rigidly supported by the supporting structures 71 occurs, and in addition, due to a problem of accuracy of the foundation, it is difficult to ensure that the top heights of the supporting structures 71 are consistent. Based on this, the bottom of the front supporting wheel 52 is set higher than the bottom of the rear supporting wheel 52, and the top of the two corresponding front supporting structures 71 is also higher than the top of the two corresponding rear supporting structures 71, so that the supporting structures 71 can be in matching contact with the corresponding supporting wheels 52. So, during the drawing of patterns, automobile body 5 walks to drawing of patterns station in-process along jacking track 4, and supporting wheel 52 on the automobile body 5 rolls on corresponding bearing structure 71, realizes automobile body 5 and bearing structure 71's rigid support, through the accurate laminating of the bolted connection of bearing structure 71 and ground, finally realizes the rigid support of automobile body 5 and ground, through the area of contact of bearing structure 71 increase with the ground, avoids automobile body 5's reaction force to lead to the ground to subside. Due to the stepped design of the support wheels 52 with high front and low rear, the high support wheels 52 on the front side do not interfere with the low support structures 71 on the rear side, the high support wheels 52 on the front side move to the high support structures 71 on the front side, the low support wheels 52 on the rear side are supported on the low support structures 71 on the rear side at this time, and after demolding is completed, the vehicle body 5 can be retracted.
Further, the two front support wheels 52, i.e., the support wheel 52 at the front left position and the support wheel 52 at the front right position, may have a height difference at the top, because the support wheel 52 at the left side and the support wheel 52 at the right side do not interfere with each other, and therefore, it is sufficient to ensure that the bottom of the support wheel 52 at the front side is higher than the bottom of the adjacent support wheel 52 at the rear side among the plurality of support wheels 52 at the left side.
Alternatively, the number of the support wheels 52 is an even number, and is greater than four, and in the forward direction of the vehicle body 5, the bottom height of the support wheels 52 on the front side is higher than the bottom height of the support wheels 52 on the rear side, and the top height of the support structure 71 on the front side is higher than the top height of the support structure 71 on the rear side.
Here, the number of the support wheels 52 is an even number, half of the number is located on the left side in the advancing direction of the vehicle body 5, and half of the number is located on the right side in the advancing direction of the vehicle body 5, and it is understood that the larger the number of the support wheels 52 is, the larger the required number of the support structures 71 is, the larger the contact area of the vehicle body 5 with the ground is, the lower the risk of sinking of the jacking rail 4 is, and at the same time, the lower the possibility of elastic deformation of the vehicle body 5 is.
In order to facilitate the arrangement of more support structures 71, the support structures 71 are preferably block-shaped structures, so that the length of the block-shaped structure 71 is short, more support structures 71 can be arranged at the demolding station, each support structure 71 supports one support wheel 52, and in addition, the support structures 71 with short length can more easily ensure that the heights of the tops of the support structures are consistent, namely the top surfaces of the support structures are not inclined, or even if the support structures are inclined, the inclination phenomenon can be ignored due to the short length, and the support structures can better match with the support wheels 52.
It should be noted that the mold 3 includes a mold body and a mold jacking block, the mold jacking block is connected to the mold body, the mold jacking block is suitable for moving in the vertical direction relative to the mold body to jack up the track plate 6, and the bottom ends of the plurality of mold jacking blocks are arranged in one-to-one correspondence with the plurality of jacking cylinders 51. Here, every template jacking piece is equivalent to a drawing of patterns point, and during the drawing of patterns, the piston rod of a plurality of jacking cylinder 51 stretches out simultaneously, realizes the template jacking piece in the synchronous jacking mould 3, and the separation of track board 6 and mould 3 can be realized to the synchronous slow jacking track board of template jacking piece to a take the altitude after, and in this process, track board 6 atress is even, slowly the mould. Therefore, the number of the jacking cylinders 51 is the same as that of the module jacking blocks, the number of the supporting wheels 52 can be equal to that of the jacking cylinders 51, when the number of the supporting wheels 52 is equal to that of the jacking cylinders 51, each supporting wheel 52 is compared with one jacking cylinder 51, the number of the supporting wheels 52 can also be larger than that of the jacking cylinders 51, and the redundant supporting wheels 52 are symmetrically distributed on the left side and the right side of the vehicle body 5.
It is understood that the supporting wheels 52 are connected with the vehicle body 5 through wheel frames, that is, the wheel frames are fixed at the lower side of the vehicle body 5, and the supporting wheels 52 are installed at the bottom ends of the wheel frames, and under the condition that each supporting wheel 52 has the same size, the height of the bottom of the installed supporting wheel 52 is different through the wheel frames with different lengths.
Referring to fig. 2 and 3, optionally, the support structure 71 is disposed on a support platform 7, the support platform 7 is disposed on a foundation, and a tie plate 72 is adapted to be disposed between the support platform 7 and the support structure 71.
Here, the supporting structure 71 is not directly connected to the foundation in contact, but is directly connected to the foundation in contact with the supporting platform 7, and the supporting platform 7 may be closely connected to the foundation by bolts, and although the supporting platform 7 is longer than a separate supporting structure, the supporting platform 7 is shorter than the lifting rail 4, and is more easily closely connected to the foundation to prevent settlement. By providing the support platform 7, the base plates 72 with different thicknesses can be arranged between the support platform 7 and the support structure 71 to meet different height requirements of the top of the support structure 71, and the support structure 71 and the support platform 7 can be connected by bolts.
Referring to fig. 2, alternatively, in the advancing direction of the vehicle body 5, a rear end of the support structure 71 is provided with a guide surface structure 711, or both a front end and a rear end of the support structure 71 are provided with the guide surface structure 711.
Here, by providing a guide surface structure 711 at the rear end of the support structure 71, the support wheels 52 are made to roll more easily onto the support structure 71.
Referring to fig. 4 and 5, the mobile automatic demolding vehicle further comprises a motor 8 and a transmission mechanism 81, wherein the motor 8 is in driving connection with the rail wheel 53 through the transmission mechanism 81.
Here, the rail wheel 53 is driven to travel by the power provided by the motor 8, so that the automation degree is higher, and the start and stop are convenient to control.
Optionally, portable automatic drawing of patterns car still includes control system, the encoder is installed to motor 8, be provided with the sensor on the automobile body 5, drawing of patterns station department and parking station department are provided with induction system, work as the sensor detects park the station or drawing of patterns station department during induction system, control system sends the vehicle instruction of stopping, in order to control automobile body 5 is in park the station or drawing of patterns station department parks, the encoder is suitable for the detection the walking distance of automobile body 5.
Here, the control system is composed of an electric console, a PLC control system, and the like. The control system is connected with an electric control cabinet on the vehicle body 5 through a drag chain. The control system detects the rotating speed and the displacement of the rail wheel on the vehicle body 5 through the encoder arranged on the vehicle body to realize the initial positioning and the parking of the vehicle body 5, and detects the distance between the mobile demolding vehicle and the induction device at the demolding station in real time through the sensor to realize the accurate positioning of the demolding vehicle.
