The composite slab production and processing system mainly includes the main devices such as the mold platform, rack, material distribution device, steam curing device, and auxiliary devices such as casting mold frame and composite slab hanger. Its main production process is to fix the side mold on the mold platform through the casting mold frame, pour concrete with the material distribution device, and then send it to the steam curing device for curing. In this process, the composite slab is transported with the help of the composite slab hanger.

[0003] In the entire production process, the clamping device of the casting mold frame is also one of the indispensable parts. The clamping device can fix the relative position relationship of the casting mold frame to avoid the expansion of the mold during the material pouring, which affects the forming quality of the composite board. However, there are many problems with the existing clamping device of the casting mold frame during use, resulting in a short service life and many problems. For example, the clamping distance of some clamping devices is fixed or the adjustment range is very small, which cannot meet the flexible production requirements of parameter changes; for example, although some holding devices can adjust the distance, the casting material is easily retained on the sliding rod or screw, which makes it difficult to use or even completely unusable; in addition, some clamping devices cannot adapt to the mechanized and automated driving mechanism to adjust the clamping distance, and the locking clamping distance also has the problems of inconvenient operation and loose locking.

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0029] A clamping device for a composite plate casting mold frame comprises a slideway 2 mounted above a casting mold frame 9, supports 1 with relatively fixed axial positions are provided at both ends of the slideway 2, the slideway 2 is in a hollow cylindrical shape and has an axial opening on the bottom surface, an end block 3 is provided at the end of the slideway 2, a fixed block 4 is provided near the middle of the slideway 2, a screw 5 extending axially along the slideway 2 is rotatably connected between the end block 3 and the fixed block 4, a slider 6 which can be controlled to move along the screw 5 is provided on the screw 5, the end block 3 is located at the top of the support 1, the fixed block 4 is fixedly connected to the inner wall of the slideway 2, a vertically extending connecting arm 61 is provided at the bottom of the slider 6, a clamping block 63 is provided at the lower end of the connecting arm 61, and the two clamping blocks 63 are pressed against the outer side of the casting mold frame 9 relative to the frame plate. It can be understood that the screw 5 is rotatably connected to the fixed block 4 and the end block 3 respectively but is fixed in the axial direction. The two clamping blocks 63 are pressed against the outer side of the casting mold frame 9 relative to the frame plate. The slider 6 can drive the clamping block 63 to move between the end block 3 and the fixed block 4 near the middle, that is, the distance between the clamped casting mold frames 9 can be close to the distance of the entire slide 2, or close to the distance between the two fixed blocks 4. The adjustment range is extremely large. Moreover, since the slide 2 opens downward, the moving parts such as the screw 5, the slider 6, and the clamping block 63 are all located inside or below the slide 2, which can effectively prevent the casting material from dripping and being retained on the moving parts during the material pouring process, thereby ensuring the stability and efficiency of the production process and extending the service life of the components. An adjusting rod 62 is passed through the lower end of the connecting arm 61 and then connected to the clamp block 63. The adjusting rod 62 can adjust the distance between the clamp block 63 and the connecting arm 61, so that the connecting arm 61 can avoid the fastening elements on the casting mold frame 9 of the positioning composite plate 8, and can also make the distance between the clamp block 63 and the connecting arm 61 close enough to increase the strength.

[0030] Furthermore, the space enclosed by the cross-sectional profile of the slide 2 is a rounded triangle, and the top of the slide 2 corresponds to one corner of the triangle. The width direction of the axial middle of the slide 2 is necked down to form a slurry passing area 21, and the slurry passing area 21 and the slides 2 on both sides of the slurry passing area 21 smoothly transition. It can be understood that the rounded triangle is a more preferred solution. The core idea is to avoid the appearance of a plane on the top surface of the slide 2 that is easy to drip and retain the casting material. For example, the most common rectangle of the slide rail, in addition to the rounded triangle, the arch shape, the top surface with a circular arc transition body, the ellipse, etc. are all possible. The most preferred solution is a rounded isosceles triangle, so that the force is more balanced and the overall structure is more stable. A slurry passing area 21 is arranged in the axial middle part of the slide 2. The width of the slurry passing area 21 is very small and close to the plate thickness of the slide 2. Obviously, in order to compress the original inner cavity, the folded edge of the lower end of the slide 2 is removed. Thanks to the fact that the overall structure is divided into left and right parts and both sides are provided with fixed blocks 4, end blocks 3 and sliders 6, even if the middle part is necked down to a slurry passing area 21 with a smaller width, it will not significantly affect the axial strength, which can be ignored for the clamping requirements. However, the benefits brought are obvious. That is, in the material pouring process, the pouring port can pass through the slurry passing area 21, and the smaller width can better prevent the pouring material from dripping and retaining.

[0031] Furthermore, a cylindrical clearance cavity is provided at one end of the end block 3 away from the slider 6, and the screw 5 axially passes through the end block 3 and extends into the clearance cavity. The end of the screw 5 located in the clearance cavity is provided with a driving block 51, and the driving block 51 can act with the output end of the prime mover to drive the screw 5 to rotate. The plug-in connection in the clearance cavity can limit the rotation of the screw 5. It can be understood that when the degree of automation is high, a plug compatible with the driving block 51 can be inserted into the clearance cavity, and the outer end of the plug is fixedly connected to the output end of the prime mover such as a motor or an electric cylinder, so as to realize fully automated mechanized driving and locking. When the degree of automation is low, a semi-automatic operation can be realized by manually drilling a fixed plug to insert the driving block 51 into the clearance cavity to rotate it, and then inserting the brake plug 7 after it is in place.

[0032] Further, the driving block includes a transition section close to the port of the clearance cavity and a clamping section away from the port of the clearance cavity, the transition section is a cambered pyramid or a cambered cone, and the clamping section is a prism that is adapted to the transition section and corresponds to the circumference. It can be understood that the front end is set as a cambered pyramid or a cambered cone, so that the plug or brake plug 7 fixed on the prime mover mechanism can be sleeved on the outside of the driving block 51, and the rear end is set as a prism, so that the structure is more stable and the force is more uniform. It can be set as a three-sided, four-sided, five-sided, six-sided, etc. For universality, it is preferably a six-sided in this embodiment.

[0033] Furthermore, the inner side wall of the clearance cavity is provided with an axially extending brake groove 31, the brake plug 7 includes a column 71 adapted to the clearance cavity, a prism cavity 72 adapted to the clamping section is provided in the middle of the end face of the column 71, and a brake ridge 73 adapted to the brake groove 31 is provided on the outer side of the column 71. It can be understood that the clearance cavity is cylindrical, which facilitates the smooth rotation of the plug fixed on the prime mover, and then smoothly drives the screw 5 to rotate and the slider 6 to translate, and finally realizes the distance between the clamping blocks 63; the brake groove 31 and the brake ridge 73 are provided to prevent the brake plug 7 from rotating. Preferably, the brake groove 31 and the brake ridge 73 are respectively provided on the bottom surface of the clearance cavity and the column 71, so that it is convenient to observe during plugging and unplugging.

[0034] Furthermore, one end of the column 71 away from the screw 5 extends out of the clearance cavity, and the outer wall of the column 71 extending out of the clearance cavity is provided with a boss 74, and the end face of the column 71 extending out of the clearance cavity is provided with a pull ring 75. Furthermore, a magnetic ring is provided at the bottom of the clearance cavity corresponding to the position of the brake plug 7, and a clearance hole for the screw 5 to pass through is provided in the middle of the magnetic ring. It can be understood that the provision of the boss 74 can limit the insertion depth, and the provision of the pull ring 75 facilitates the insertion and removal of the brake plug 7. The preferred solution is that the pull ring 75 is vertically arranged to avoid the retention of the pouring slurry that accidentally drips. The provision of the magnetic ring can attract the brake plug 7, making the insertion process more labor-saving, because if the position of the screw 5 and the drive block 51 is not aligned during insertion, it is necessary to gradually adjust it through the transition section, and the magnetic force can have a labor-saving effect. In addition, it can also avoid accidental slipping during the working process, which is safer and more reliable.

[0035] Furthermore, one end of the end block 3 away from the slider 6 extends out of the slideway 2, and the outer wall of the end block 3 extending out of the slideway 2 is provided with a radially protruding rib 32, and the area surrounded by the rib 32 is larger than the area surrounded by the outer contour of the slideway 2. It can be understood that the provision of the rib 32 can limit the insertion depth, and can also transfer the force on the fixed block 4 to the support 1 and then to the frame through the slideway 2 and the end block 3. In practice, the end block 3 and the support 1 are generally made into one piece. In this technical solution, for the convenience of description, different parts are named separately, but it does not mean that they are two separate parts. It can be formed into one piece or connected in parts. The more important advantage is that the end block 3 can be connected to the slideway 2 only by plugging and unplugging. Once the screw 5 and the slider 6 inside the slideway 2 need to be repaired and replaced, it can be achieved by pulling out the end block 3, which is very convenient.

[0036] Furthermore, the support 1 is formed into an inverted T shape by a support plate and a support rod, a slot 12 is provided at the bottom of the support plate, the bottom surface of the slot 12 coincides with the bottom surface of the support plate, the side of the slot 12 facing the casting mold frame 9 coincides with the side of the support plate facing the casting mold frame 9, and the side of the slot 12 away from the casting mold frame 9 is in an arc shape. It can be understood that an ordinary support plate without a slot 12 usually only has a fixing hole 11 formed on the support plate to achieve fixed connection with the frame, and the slot 12 is provided so that there is space below the edge of the plate surface that is particularly suitable for the frame, the slot 12 is hung on the edge of the plate surface, the fixed block 4 and the screw rod 5 have a pulling force on the end block 3, and the end block 3 is integrated or connected with the support 1, thereby forming a whole, and disassembly is also extremely convenient.

[0037] Furthermore, a detachably connected backing plate 13 is provided in the card slot 12, and the backing plate 13 can fill the card slot 12 to make the bottom surface of the support plate flush, and a magnetic block 14 that can absorb the backing plate 13 is provided on the top surface of the card slot 12. It can be understood that the backing plate 13 can be used for two purposes, and the magnetic block 14 can absorb the backing plate 13 to prevent it from falling during movement. A more preferred solution is that the backing plate 13 is made into a plurality of sub-plates with different thicknesses, so that it can adapt to the edges of racks with different thicknesses.
