Description

TECHNICAL FIELD

[0002] Double-skin wall is composed of two parallel concrete wallboards with a thickness of at least 5 cm connected at a certain distance by steel bar trusses. Compared with solid walls, double-skin walls have a lower self-weight and lower transportation costs.

[0003] In the process of producing double-skin wall in a prefabrication factory, the first wallboard is usually produced first, and after the production and maintenance of the first wallboard are completed, a special turnover device is used to cover the first wallboard that has been maintained on the second wallboard that has just been poured, and the first and second wallboards are combined in place by shaking and vibrating before being put into the kiln for maintenance. However, the existing turnover device (such as Chinese patent CN217834011U) may not turn to the right position (the turning angle is less than 180°), may turn too much (the turning angle is greater than 180°), or may run out of position (the turnover frame rotates again) when performing subsequent work after the turning is completed, which may result in the first wallboard and the second wallboard not being properly aligned, and the double-skin wall product produced may not be qualified.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Please see Figure 1 An embodiment of the tilting machine of this utility model includes a truss track 1 and a traveling trolley 2. The truss track 1 is fixedly installed on the ground, and the traveling trolley 2 is installed on top of the truss track 1. The truss track 1 is used to support the traveling trolley and allow the traveling trolley 2 to move safely. A tilting station 3 and a vibration station 4 are arranged below the truss track 1, that is, the truss track 1 spans the tilting station 3 and the vibration station 4, allowing the traveling trolley 2 to move between the tilting station 3 and the vibration station 4.

[0038] Please see Figure 2 The traveling trolley 2 consists of a trolley body 21, a lifting mechanism 22, and a tilting pallet 23.

[0039] The vehicle body 21 is equipped with a travel motor and limit switches. Driven by the travel motor, the vehicle body 21 can start, stop, and move on the truss track 1 according to a set program. The lifting mechanism 22 is mounted on the vehicle body 21.

[0040] Please see Figure 3 , Figure 4The lifting mechanism 22 includes a drive system 221, a pulley mechanism 222, and a lifting beam 223. The drive system 221 is fixedly mounted on the vehicle body 21. The drive system 221 includes a lifting motor 2211 and a winch assembly 2212. The output shaft of the lifting motor 2211 is connected to the rotating shaft of the winch assembly 2212. The pulley mechanism 222 includes fixed pulley supports 2221 installed at both ends of the vehicle body 21, fixed pulleys 2222 installed on the fixed pulley supports 2221, movable pulleys 2223 installed on the lifting beam 223, and overload protection loads 2224 installed on the fixed pulley supports 2221. The wire rope (or chain) of the hoisting assembly 2212 passes around the fixed pulleys 2222 and the movable pulleys 2223 in sequence and connects to the overload protection loads 2224 installed on the fixed pulley supports 2221. The drive system 221 drives the wire rope (or chain) to realize the lifting and lowering drive of the lifting beam 223. During the lifting and lowering drive, it can start, stop, lift and lower according to the set program.

[0041] Please see Figure 5 The overload protection load 2224 includes a base 22241, a T-shaped moving rod 22242 installed in the base 22241, a spring 22243 sleeved on the moving rod 22242, a first limit switch 22244 and a second limit switch 22245 installed on the base 22241. The wire rope (or chain) of the hoisting assembly 2212 passes around the movable pulley 2223 and is connected to the moving rod 22242. During the lifting and lowering of the lifting beam 223, the moving rod 22242 moves accordingly. When the moving rod 22242 contacts the first limit switch 22244, the first limit switch 22244 sends a full load signal. When the moving rod 22242 contacts the second limit switch 22245, the second limit switch 22245 sends an extreme overload signal.

[0042] Please see Figure 6A vertical lifting guide mechanism and a vertical lifting locking mechanism are provided between the lifting beam 223 and the fixed pulley support 2221, so that the lifting beam 223 can move stably or be locked in the vertical direction. The vertical lifting guide mechanism includes a guide bracket 2225 fixed below the fixed pulley support 2221 and a guide rod 2226 fixed above the lifting beam 223; the guide bracket 2225 is a frame structure with good rigidity, and a guide sleeve 2227 is provided at its lower part. The bottom of the guide sleeve 2227 is flared to facilitate fitting with the guide rod 2226; the lower end of the guide rod 2226 is fixedly connected to the lifting beam 223, and the top is conical to facilitate fitting into the guide sleeve 2227; when the lifting beam 223 moves in the vertical direction, it is guided by the sliding of the guide rod 226 within the guide sleeve 2227. The vertical lifting locking mechanism includes multiple first transverse holes arranged along the length of the guide rod 2226, a second transverse hole arranged on the guide sleeve 2227, and a first pin 2228 mounted on the guide bracket 2225. The first and second transverse holes are horizontally arranged and have the same diameter. The diameter of the first pin 2228 is adapted to the diameter of the first and second transverse holes. When the lifting beam 223 is lifted to the set position, the second transverse hole on the guide sleeve 2227 aligns with a first transverse hole on the guide rod 2226. At this time, the first pin 2228 is inserted into the first and second transverse holes, thereby locking the lifting mechanism 22. The first pin 2228 is preferably a telescopic rod of hydraulic cylinder, pneumatic cylinder, or electric push rod.

[0043] Please see Figure 7 The tilting tray 23 is rectangular in shape, with rotating hinge points at the middle of both ends. The tilting tray 23 is hinged to the corresponding lifting beam 223 located below the vehicle body 21 via the rotating hinge points and a horizontal axis, allowing the tilting tray 23 to rotate around the horizontal axis. A tilting locking mechanism and a tilting limit mechanism are provided between the tilting tray 23 and the lifting beam 223.

[0044] The flipping locking mechanism includes a locking pin seat 231 on the flipping tray and a second pin 232 mounted on the lifting beam 223. The locking pin seat 231 has a pin hole. The flipping limiting mechanism includes a limiting boss 233 on the lifting beam 223. When the flipping tray 23 flips to the set position, the pin hole on the locking pin seat 231 aligns with the second pin 232 mounted on the lifting beam 223, and the second pin 232 is inserted into the pin hole on the locking pin seat 231 to lock the flipping action; at the same time, the locking pin seat 231 just contacts the limiting boss 233 to prevent over-flipping.

[0045] Please see Figure 8A tilting drive device is provided around the rotation hinge point of the tilting tray 23. The tilting drive device is preferably a gear set or a worm gear set. The mold table clamping mechanism 234 and the wall panel pressing mechanism 235 are evenly distributed on both sides of the tilting tray 23.

[0046] The mold table clamping mechanism 234 is located inside the flipping tray 23. (See also...) Figure 9 The mold table clamping mechanism 234 includes clamping supports 2341, a swing arm 2342, and a swing arm cylinder 2343 mounted on the frame of the flip tray 23. The actuating rod of the swing arm cylinder 2343 is connected to the free end of the swing arm 2342. Several clamping supports 2341 are evenly distributed inside the frame of the flip tray 23, with their lower surfaces at the same height. When the lifting beam 223 lowers simultaneously with the flip tray 23, each clamping support 2341 is brought close to the upper surface of the mold table 5. At this time, the swing arm cylinder 2343 is activated, and the swing arm 2342, hinged to the flip tray 23, rotates upward to clamp the mold table 5. The end of the swing arm 2342 is designed with an arc-shaped protrusion structure, making it easier for the swing arm 2342 to clamp the mold table 5.

[0047] Please see Figure 10 The wall panel clamping mechanism 235 includes a clamping bracket 2351, a clamping cylinder 2352, and a long pressure plate 2353. One end of the clamping bracket 2351 and the cylinder body of the clamping cylinder 2352 are respectively hinged to the tilting tray 23. The other end of the clamping bracket 2351 is hinged to the actuating rod of the clamping cylinder 2352. One end of the long pressure plate 2353 is detachably connected to the clamping bracket 2351, and the other end interferes with the component 6 mounted on the mold table 5. Under the push of the clamping cylinder 2352, the clamping bracket 2351 can rotate freely, so that the long pressure plate 2353 can clamp the component 6. In this way, since both ends of the clamping cylinder 2352 are hinged to the tilting tray 23 and the clamping bracket 2351 respectively, that is, both ends of the clamping cylinder 2352 can rotate, so that the clamping cylinder 2352 will not be subjected to a force perpendicular to its actuating rod, thus effectively protecting the clamping cylinder 2352. In this embodiment, a circular tube is welded onto the clamping bracket 2351, and a long pressure plate 2353 is inserted into the circular tube to form a detachable connection.
