Description

Technical Field

[0001] This utility model belongs to the field of transportation, and more specifically, it relates to a transportation device for precast concrete components. Background Technology

[0002] Precast concrete slabs are a common type of precast concrete component. Simple building walls can be constructed using precast concrete slabs, which greatly simplifies the construction process. However, because precast concrete slabs are large and heavy, they are prone to cracking and damage upon impact, making them inconvenient to transport and requiring specialized transport equipment.

[0003] The common method for transporting precast concrete components involves hoisting support beams onto a semi-trailer, then hoisting and erecting the precast concrete slabs onto the support beams for support. However, because semi-trailers are already quite tall, the precast concrete slabs on them have a higher center of gravity. During transport, especially during sharp turns, the slabs are prone to swaying from side to side, potentially causing the vehicle to overturn, posing a significant safety hazard. Furthermore, on uneven roads, the up-and-down jolting during transport can cause the slabs to collide with their support beams, easily leading to cracking. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a transportation device for precast concrete components, thereby solving the problem that precast components are prone to shaking and falling during transportation using existing transportation devices.

[0005] This utility model provides a transportation device for precast concrete components, achieved through the following specific technical means:

The hydraulic telescopic rod A is inserted and fixedly fixed in the mounting base, and the front end of the hydraulic telescopic rod A is fixedly connected to the movable block. Two sets of fixing components are installed inward on each of the two upper support plates. The fixing components clamp the precast concrete slab in the unloading device.

[0008] Furthermore, a groove is provided on the rearmost support beam above the side beam, and a limiting plate is inserted in the groove. The limiting plate is locked at the rear end of the rear component support beam of the unloading device.

The shock-absorbing spring surrounds the outside of the first guide rod and is located between the buffer plate and the front fixed plate.

[0010] Furthermore, the buffer plate rests against the outside of the front component support beam of the unloading device.

[0011] Furthermore, the fixing assembly includes a hydraulic telescopic rod B, a hinge plate, a hinge shaft, a fixed plate, a rotating shaft connecting rod, a second guide rod, a limiting block B, a buffer spring, a mounting plate, a mounting side plate, and an anti-slip rubber block.

A protective rope is connected to one of the two cantilever arms at the upper end of the component support beam. The protective rope passes around the precast concrete slab, through an ear plate on the other cantilever arm, and is then tied to an ear plate on the lifting track. A partition plate and a precast concrete slab are held between the two cantilever arms of the component support beam, with the partition plate and precast concrete slab spaced apart. Sleepers are placed in grooves in the base plate, resting under the partition plate and precast concrete slab.

[0013] Furthermore, the block is engaged on the outside of the lifting track, forming a sliding connection in the inclined direction.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 9 As shown:

[0031] This utility model provides a transportation device for precast concrete components, including a support beam 1, an upper support plate 4, a side beam 5, a lower support plate 6, a front beam 7, a wheel 8, a front fixing plate 9, a buffer assembly 10, a traction assembly 11, a traction plate 111, a limiting block A112, a rotating shaft 113, a connecting shaft 114, a traction ring 115, a lifting assembly 12, a mounting base 121, a hydraulic telescopic rod A122, a movable block 123, a fixing assembly 13, and a precast concrete slab 21;

[0032] There are three sets of support beams 1. Each support beam 1 is fixedly connected to the upper support plate 4 at its lower end. The upper support plate 4 is fixedly connected to the side beam 5 at its lower end. The side beam 5 is fixedly connected to the lower support plate 6 at its lower end. The front end of the side beam 5 is fixedly connected to the front beam 7. The wheels 8 are divided into three groups of two. One group of wheels 8 is set at the front position of the side beam 5, and two groups of wheels 8 are set at the rear position of the side beam 5. The connecting shafts of the wheels 8 are fixedly connected to the outside of the side beam 5. A front fixing plate 9 is fixedly connected to the rear of the side beam 5. A traction assembly 11 is fixedly connected to the front of the front beam 7. The traction assembly 11 includes a traction plate 111, a limiting block A112, a rotating shaft 113, a connecting shaft 114, and a traction ring 115. The two traction plates 111 are fixedly connected to the front of the front beam 7, and the rotating shaft 113 is inserted through the traction plates 111. A rotating connection is formed, with a limiting block A112 welded above the rotating shaft 113, and the limiting block A112 attached to the upper end of the traction plate 111; the middle of the rotating shaft 113 is fixedly connected to one end of the connecting shaft 114, and the other end of the connecting shaft 114 is fixedly connected to the traction ring 115; five sets of lifting components 12 are installed inward on each of the two lower support plates 6, and the lifting components 12 include a mounting base 121, a hydraulic telescopic rod A122, and a movable block 123; the bottom of the mounting base 121 is fixedly connected to the lower support plate 6, and the hydraulic telescopic rod A122 is inserted and fixed in the mounting base 121, and the movable block 123 is fixedly connected to the front end of the hydraulic telescopic rod A122; two sets of fixing components 13 are installed inward on each of the two upper support plates 4, and the fixing components 13 clamp the precast concrete slab 21 in the unloading device.

[0033] Among them, such as Figure 1 As shown, a groove 2 is provided on the rearmost support beam 1 above the side beam 5. A limiting plate 3 is inserted in the groove 2. The limiting plate 3 is locked at the rear end of the rear component support beam 17 of the unloading device. When the unloading device enters and is lifted off the ground by the lifting component 12, the limiting plate 3 limits and locks it to prevent the lifting track 14 from sliding on the movable block 123, so that the unloading device can be separated from the transport device.

[0034] Among them, such as Figure 5As shown, a buffer assembly 10 is provided on the front fixed plate 9. The buffer assembly 10 includes a buffer plate 101, a first guide rod 102, a shock-absorbing spring 103, a guide hole 104, and a limiting plate 105. The buffer plate 101 is located behind the front fixed plate 9. Five first guide rods 102 are fixedly connected to the front of the buffer plate 101. The first guide rods 102 pass through the guide holes 104 provided on the front fixed plate 9 to form a sliding connection. The front end of the first guide rod 102 is fixedly connected to the limiting plate 105. The shock-absorbing spring 103 surrounds the outside of the first guide rod 102 and is located between the buffer plate 101 and the front fixed plate 9. The buffer plate 101 abuts against the outside of the front component support beam 17 of the unloading device. When the transport device reverses to allow the unloading device to enter, the component support beam 17 of the unloading device contacts the buffer plate 101 first. The buffer assembly 10 can prevent the impact caused by the rigid contact when the unloading device enters the transport device from damaging all support beams and support plates.

[0035] Among them, such as Figure 9 As shown, the fixing assembly 13 includes a hydraulic telescopic rod B131, a hinge plate 132, a hinge shaft 133, a fixing plate 134, a rotating shaft connecting rod 135, a second guide rod 136, a limiting block B137, a buffer spring 138, a mounting plate 139, a mounting side plate 1310, and an anti-slip rubber block 1311. The hinge plate 132 is fixedly connected to the upper support plate 4 and hinged to one end of the hydraulic telescopic rod B131. The other end of the hydraulic telescopic rod B131 is fixedly connected to the hinge shaft 133, which is hinged to the upper ends of the two fixing plates 134. The lower ends of the fixing plates 134 are fixedly connected to the rotating shaft connecting rod 135, and the lower end of the rotating shaft connecting rod 135 is hinged to the hinge plate 132. A fixing block is provided between the fixing plates 134, and five second guide rods 136 are fixedly connected to one side of the fixing plate 134. A limiting block B137 is provided on the second guide rod 136, and the limiting block B137 passes through the groove provided on the mounting plate 139; a buffer spring 138 is surrounded on the outside of the middle second guide rod 136, and the buffer spring 138 is located between the fixing plate 134 and the mounting plate 139; mounting side plates 1310 are provided on both sides of the mounting plate 139, and anti-slip rubber blocks 1311 are installed in front of the mounting side plates 1310; when the transport device reverses to allow the unloading device to enter, the hydraulic telescopic rod B131 of the fixing component 13 extends, causing the rotating shaft connecting rod 135 to rotate towards the side of the precast concrete slab 21 until the anti-slip rubber block 1311 contacts the precast concrete slab 21 and applies a certain pressure, the rotation stops, and the fixing component 131 clamps the middle partition 20 and the precast concrete slab 21 to prevent left and right swaying and damage during transportation.

[0036] Among them, such as Figure 3As shown, the unloading device includes a lifting track 14, a base plate 15, sleepers 16, a component support beam 17, ear plates 18, a protective rope 19, a partition plate 20, and a precast concrete slab 21. The lifting track 14 is fixedly connected to both sides of the base plate 15. The component support beam 17 is fixedly connected to the front and rear of the lifting track 14. One of the two cantilever arms at the upper end of the component support beam 17 is connected to a protective rope 19. The protective rope 19 passes around the precast concrete slab 21, through the ear plate (18) set on the other cantilever arm, and is then tied to the ear plate 18 set on the lifting track 14. The partition plate 20 is held between the two cantilever arms of the component support beam 17. The precast concrete slab 21 and the partition plate 20 are distributed alternately. The bottom plate 15 has a groove in which sleepers 16 are placed, which rest under the partition plate 20 and the precast concrete slab 21. The bottom plate 15 is positioned very low, and correspondingly, the height of the center of gravity of the precast concrete slab 21 on the transport device is also greatly reduced, which is conducive to maintaining stability when turning during transport. When the transport encounters uneven road sections, the sleepers 16 under the precast concrete slab 21 can prevent the precast concrete slab 21 from being impacted and cracked from the bottom up when it is bumped, thus ensuring the integrity of the precast concrete slab 21 during the movement.

[0037] Among them, such as Figure 1 As shown, the movable block 123 is locked on the outside of the lifting track 14, forming a sliding connection in an inclined direction. The hydraulic telescopic rod A122 extends, causing the movable block 123 to press against the lifting track 14 and lift it upward, so that the unloading device leaves the ground and is easy to transport.

[0038] The specific usage and function of this embodiment are as follows:

[0039] In this invention, the precast concrete slab 21 is hoisted onto the sleepers 16 placed on the bottom plate 15 between the component support beams 17 of the unloading device, with a partition 20 separating the two to prevent damage from contact and collision. A protective rope 19 is passed over the precast concrete slab 21 on the side closest to the middle of the bottom plate 15, and the end of the protective rope 19 is tied to the ear plate 18 set on the lifting rail 14. The transport device reverses and gradually incorporates the unloading device until it is fully incorporated. After the buffer plate 101 of the buffer assembly 10 contacts the component support beam 17, the buffer plate 101 moves along the direction of the first guide rod 102, and the shock-absorbing spring 103 cushions the contact. Impact is buffered; the limiting plate 3 is inserted and placed into the slot 2 of the last support beam 1; the hydraulic telescopic rod A122 extends, causing the movable block 123 to press against the lifting rail 14 and lift upward, and the unloading device gradually leaves the ground to a certain height; the hydraulic telescopic rod B131 of the fixing component 13 extends, causing the rotating shaft connecting rod 135 to rotate towards the concrete precast slab 21 until the anti-slip rubber block 1311 contacts the concrete precast slab 21 and applies a certain pressure, the rotation stops, and the fixing component 131 clamps the middle partition 20 and the concrete precast slab 21; finally, the tractor hooks the traction ring 115 to drive the transport device forward.
