Abstract
Description
Technical Field
[0001] This application relates to the field of precast wall panel transportation technology, and in particular to a fixing device for transporting precast building wall panels. Background Technology
[0002] Precast wall panels are wall panels that are prefabricated in a factory and can be directly installed and used. Precast wall panels are typically made of concrete, lightweight panels, or other composite materials, and are characterized by standardization and modularity, which greatly improves the efficiency of building construction. The precast wall panel transport and securing device is a specialized piece of equipment designed to ensure the safety and stability of the precast wall panels during transportation.
[0003] Existing precast wall panel transport and fixing devices mainly consist of a base and support components. The base typically has mounting holes for fixing it to the transport vehicle, and the support frame is usually machined to form an L-shaped support area for supporting the precast wall panels. The L-shaped support area is usually inclined. When loading precast wall panels, a hoist is usually used to place the precast wall panels on the support components, and the unloading process is the reverse.
[0004] The existing technical solutions mentioned above have the following drawbacks: precast wall panels are usually large in size and heavy in weight. When loading multiple precast wall panels continuously, the crane operator needs to adjust the placement of the precast wall panels multiple times. If the precast wall panels are not placed properly, it may increase the difficulty of placing the subsequent precast wall panels and make it inconvenient to place the precast wall panels on the fixed device. Utility Model Content
[0005] This application provides a fixing device for transporting precast wall panels to facilitate the placement of precast wall panels on the fixing device.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:
[0007] A fixing device for transporting precast wall panels includes a base, a support plate fixedly connected to the base, a support block fixedly connected to the base, and multiple support seats rotatably mounted on the base. Each support seat is made of a bottom plate and a side plate fixedly connected together. The bottom plate is rotatably connected to the base. The base has multiple fixing slots for the support seats to be inserted into, each corresponding to one of the support seats. A rotating rod is rotatably connected to the support plate. One end of the rotating rod is rotatably connected to a crossbar. One end of the crossbar is rotatably connected to a rotating arm. One end of the rotating arm is rotatably connected to the support block. A first hydraulic rod is mounted on the support block and rotatably connected to the support block. The output end of the first hydraulic rod is rotatably connected to the crossbar. Multiple limit plates are rotatably connected to the crossbar, each corresponding to one of the support seats.
[0008] By adopting the above technical solution, the first hydraulic rod is controlled to extend and retract, driving the limiting plate to move, so that the precast wall panel on the fixing device is kept vertical or tilted. The limiting plate and the support seat separate and limit each precast wall panel on the fixing device. The support seat can rotate with the precast wall panel, ensuring that the fixing device can stably support the precast wall panel, reducing the operation of hoisting machine operators to hoist the precast wall panel onto the fixing device and place it at an angle, and making it easier for hoisting machine operators to place the precast wall panel on the fixing device.
[0009] Optionally, a mounting base is fixedly connected to the base, and at least two mounting bases are symmetrically arranged. A clamping frame is rotatably mounted on the mounting base, and a fixed plate is rotatably connected to the clamping frame. A second hydraulic rod is mounted on the mounting base, and the second hydraulic rod is rotatably connected to the mounting base. The output end of the second hydraulic rod is rotatably connected to the fixed plate. Push plates are connected to opposite sides of the two fixed plates.
[0010] By adopting the above technical solution, the extension of the second hydraulic rod is controlled to push the fixed plate to move closer to the push plate. The push plate will move with the fixed plate to fit the side wall of the precast wall panel. The two push plates can clamp and fix the side walls on both sides of the precast wall panel, increasing the stability of the precast wall panel on the fixing device.
[0011] Optionally, a fixing rod is provided through the fixing plate, a baffle is fixedly connected to one end of the fixing rod, a push plate is fixedly connected to the other end of the fixing rod, and an elastic element is sleeved on the fixing rod, with the two ends of the elastic element abutting against the fixing plate and the push plate respectively.
[0012] By adopting the above technical solution, the fixed rod and the elastic element can make the push plate move along the direction of the fixed rod, and the elastic element can reduce the damage to the precast wall panel caused by vibration, collision and other reasons during transportation, thus protecting the quality of the precast wall panel.
[0013] Optionally, the sidewall of the push plate facing the support block is machined with an inclined surface, which fits against the surface of the support block facing the support plate.
[0014] By adopting the above technical solution, one side of the push plate is in contact with the support block, which can increase the contact area between the push plate and the side wall of the precast wall panel, ensuring that the push plate can firmly clamp and fix the precast wall panel close to the support block.
[0015] Optionally, a rubber pad is fixed to the surface of the limiting plate.
[0016] By adopting the above technical solution, the rubber pad can reduce the damage to the precast wall panel caused by the sliding between the limiting plate and the precast wall panel, reduce the damage to the precast wall panel caused by vibration during transportation, protect the quality of the precast wall panel, and at the same time increase the friction between the limiting plate and the precast wall panel, ensuring that the wall panel can be firmly fixed on the fixing device.
[0017] Optionally, the bottom of the base is provided with fork holes for inserting forklift forks.
[0018] By adopting the above technical solution, the fork hole facilitates the movement of the fixing device to a designated position using a forklift, ensuring the stability of the fixing device when it is moved using a forklift.
[0019] Optionally, lifting rings are fixedly connected to both the support plate and the support block, and four lifting rings are provided in a rectangular arrangement.
[0020] By adopting the above technical solution, the lifting ring facilitates the hoisting of the fixing device to the designated position, ensuring the stability of the fixing device during hoisting.
[0021] Optionally, an anti-slip pad is fixed to the bottom of the base.
[0022] By adopting the above technical solution, the anti-slip mat can increase the friction between the fixing device and the carriage during transportation, ensuring that the fixing device can be firmly fixed in the carriage.
[0023] In summary, this application has the following technical effects:
[0024] 1. By setting up a support base, crossbar, first hydraulic rod and limiting plate, the extension and retraction of the first hydraulic rod drives the limiting plate to move, so that the precast wall panel on the fixing device is kept vertical or tilted. The limiting plate and support base separate and limit each precast wall panel on the fixing device. The support base can rotate with the precast wall panel, ensuring that the fixing device can provide stable support for the precast wall panel, reducing the operation of hoisting machine operators to hoist the precast wall panel onto the fixing device and place it at an angle, and making it easier for hoisting machine operators to place the precast wall panel on the fixing device.
[0025] 2. By setting up a mounting base, a clamping frame, a second hydraulic rod and a push plate, the extension of the second hydraulic rod is controlled to push the fixing plate to move closer to the push plate. The push plate will move with the fixing plate to fit the side wall of the precast wall panel. The two push plates can clamp and fix the side walls on both sides of the precast wall panel, increasing the stability of the precast wall panel on the fixing device.
[0026] 3. By setting rubber pads, damage to the precast wall panels caused by sliding between the limiting plate and the precast wall panels can be reduced, damage to the precast wall panels caused by vibration during transportation can be reduced, the quality of the precast wall panels can be protected, and the friction between the limiting plate and the precast wall panels can be increased to ensure that the wall panels can be firmly fixed on the fixing device.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.
[0030] This application discloses a fixing device for transporting precast building wall panels, referring to... Figure 1 The fixing device includes a rectangular base 1, a support plate 11 welded to one end of the base 1 along its length, and a support block 2 welded to the other end of the base 1 along its length. The support block 2 has a right-angled triangular cross section. The shorter right-angled side of the support block 2 is connected to the base 1, and the longer right-angled side of the support block 2 is connected to the support plate 11. The bottom of the base 1 has a fork hole 13 for the forklift fork to insert. The top of the support plate 11 and the top of the support block 2 are both welded with lifting rings 14. There are four lifting rings 14 in total, arranged in a rectangular shape. The bottom of the base 1 is glued with an anti-slip pad 15.
[0031] The forkhole 13 facilitates the movement of the fixing device to a designated location using a forklift, ensuring the stability of the fixing device when moved by a forklift. The lifting ring 14 facilitates the hoisting of the fixing device to a designated location, ensuring the stability of the fixing device when hoisting. During transportation, the anti-slip mat 15 increases the friction between the fixing device and the truck bed, ensuring that the fixing device can be securely fixed in the truck bed.
[0032] Reference Figure 1 A support seat 3 is rotatably connected to the base 1. Multiple support seats 3 are spaced apart along the length of the base 1. The support seat 3 is made of a bottom plate 31 and a side plate 32 made of strip plates, which are welded together. The side wall of the bottom plate 31 along the length is welded to the side wall of the side plate 32 along the length, and the angle between the bottom plate 31 and the side plate 32 is a right angle. The side wall of the bottom plate 31 away from the side plate 32 is rotatably connected to the base 1. The base 1 has a fixing groove 12 for the support seat 3 to be inserted. Multiple fixing grooves 12 are spaced apart and correspond one-to-one with the support plate 11. When the support plate 11 is rotated to be inserted into the fixing groove 12, the side plate 32 of the support plate 11 is parallel to the side of the support block 2 away from the base 1.
[0033] Reference Figure 1Rotating rods 4 are rotatably connected to the side walls on both sides of the support plate 11 in the height direction. A crossbar 41 is rotatably connected to the end of the rotating rod 4 away from the support plate 11. A rotating arm 42 is rotatably connected to the end of the crossbar 41 away from the rotating rod 4. The end of the rotating arm 42 away from the crossbar 41 is rotatably connected to the side wall of the support block 2. A first hydraulic rod 43 is installed on the side wall of the support block 2. The end of the first hydraulic rod 43 away from its output end is rotatably connected to the support block 2. The output end of the first hydraulic rod 43 is rotatably connected to the end of the crossbar 41 away from the rotating rod 4. A limiting plate 44 is connected between the two crossbars 41. Multiple limiting plates 44 are arranged at intervals along the length direction of the crossbars 41 and correspond one-to-one with the support base 3. The limiting plate 44 is made of a strip plate and has a rotating shaft (not shown in the figure) connected to both ends of its length direction. The limiting plate 44 is rotatably connected to the two crossbars 41 through the rotating shafts at both ends. Rubber pads 45 are glued to the surface of the two side plates 32 of the limiting plate 44.
[0034] The rotating arm 42 ensures the smooth extension and retraction of the first hydraulic rod 43, guaranteeing its operational safety and stability. The rubber pad 45 reduces damage to the precast wall panel caused by sliding between the limiting plate 44 and the precast wall panel, minimizes damage caused by vibration during transportation, protects the quality of the precast wall panel, and increases the friction between the limiting plate 44 and the precast wall panel, ensuring the wall panel is securely fixed to the fixing device.
[0035] When using this fixing device, a hoist is used to place the precast wall panels sequentially from the support block 2 towards the support plate 11 onto the support base 3. The bottom plate 31 and side plates 32 of the support base 3 are attached to the bottom of the precast wall panel, while the limiting plate 44 is attached to one side wall of the precast wall panel, so that the precast wall panel is placed vertically on the fixing device. After all the precast wall panels are placed on the fixing device, the first hydraulic rod 43 is controlled to retract to drive the crossbar 41 to rotate towards the base 1. At this time, the precast wall panel will tilt towards the support block 2 as the limiting plate 44 moves, and the support base 3 will rotate with the precast wall panel to ensure that the support base 3 can stably support the precast wall panel. When the precast wall panel near the support block 2 rotates to be attached to the support block 2, the first hydraulic rod 43 stops retracting. At this time, the two side plates 32 of the limiting plate 44 away from the support block 2 are attached to the surface of the precast wall panel, which can limit the precast wall panel and ensure that the precast wall panel can be stably fixed on the fixing device.
[0036] By controlling the extension and retraction of the first hydraulic rod 43 to move the limiting plate 44, the precast wall panels on the fixing device are controlled to remain vertical or tilted. The limiting plate 44 and the support seat 3 separate and limit each precast wall panel on the fixing device. The support seat 3 can rotate with the precast wall panel, ensuring that the fixing device can provide stable support for the precast wall panel. This reduces the operation of the hoisting machine operator to hoist the precast wall panel onto the fixing device and place it at an angle, making it easier for the hoisting machine operator to place the precast wall panel on the fixing device.
[0037] Reference Figure 1 Mounting seats 5 are welded to the side walls on both sides along the length of the base 1. A clamping frame 51 is rotatably mounted on the mounting seat 5. A fixing plate 52 is rotatably connected to the end of the clamping frame 51 away from the mounting seat 5. A second hydraulic rod 53 is mounted on the mounting seat 5. The end of the second hydraulic rod 53 away from its output end is rotatably connected to the mounting seat 5. The output end of the second hydraulic rod 53 is rotatably connected to the surface of the fixing plate 52 near the mounting plate. Fixing rods 521 are provided through the fixing plate 52, and two fixing rods 521 are spaced apart. One end of the fixing rod 521 is located on the opposite side of the two fixing plates 52 and is welded with a baffle. The two fixing rods 521 connected to the same fixing plate 52 have a push plate 54 welded to the end away from the baffle. An elastic element 522 is sleeved on the fixing rod 521. In this embodiment, the elastic element 522 is a spring. The two ends of the elastic element 522 abut against the opposite surfaces of the fixing plate 52 and the push plate 54, respectively. The side wall of the push plate 54 facing the support block 2 is machined to form an inclined surface that fits with the inclined side of the support block 2.
[0038] When using this fixing device, the second hydraulic rod 53 is extended to push the fixing plate 52 towards the push plate 54. The push plate 54 will move with the fixing plate 52 to the side wall of the precast wall panel. The two push plates 54 can clamp and fix the side walls of the precast wall panel on both sides, increasing the stability of the precast wall panel on the fixing device. One side of the push plate 54 is in contact with the support block 2, which can increase the contact area between the push plate 54 and the side wall of the precast wall panel, ensuring that the push plate 54 can firmly clamp and fix the precast wall panel near the support block 2. The fixing rod 521 and the elastic element 522 can make the push plate 54 move in the direction of the fixing rod 521. The elastic element 522 can reduce the damage to the precast wall panel caused by vibration, collision and other reasons during transportation, and protect the quality of the precast wall panel.
[0039] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
