Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting and transportation equipment, and in particular relates to a protective railing auxiliary transportation device. Background Art

[0002] River channel construction projects often involve installing guardrails. These are typically carved from marble and feature perforations to ensure aesthetic appeal and minimize visual interference. Typically, guardrails are prefabricated in a factory and transported to the construction site. The process involves loading the guardrails individually onto transport vehicles, delivering them to the site, unloading them into a material yard, and then moving them individually to their installation locations for masonry installation. Existing guardrail construction relies on auxiliary equipment and suffers from the following drawbacks: First, the guardrails must be loaded into the truck bed before transport and then unloaded from the bed upon arrival, resulting in low efficiency and safety. Second, the guardrails within the truck bed are often positioned one by one during transport, leading to potential damage from bumps and other factors during transportation. Furthermore, the material yard at the construction site is often located some distance from the installation location, making the relocation of the guardrails before installation a significant labor and resource intensive task.

[0003] In summary, it is necessary to develop and design a guardrail auxiliary transportation device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a guardrail auxiliary transportation device to improve the operational efficiency of guardrail loading and unloading, play a certain protective role for the guardrail during transportation, and improve the efficiency of guardrail construction by promoting the transfer and use of guardrails at the installation site.

[0005] The technical solution adopted by the utility model is: a guardrail auxiliary transportation device, comprising two end brackets arranged opposite to each other, a supporting beam installed between the lower parts of the two end brackets, two parallel sliding rail beams provided between the upper parts of the two end brackets, a supporting base plate fixedly installed on the supporting beam, a plurality of separation and limit assemblies installed on the sliding beam along the axial direction, the guardrail is placed on the supporting base plate, the guardrail is located between adjacent separation and limit assemblies and the top is separated and limited by the adjacent separation and limit assemblies; a top base is installed on the top of the two end brackets, and a manual limit assembly for laterally pushing the separation and limit assembly located on the outermost side is installed on the top base.

[0012] The advantages and positive effects of the utility model are:

[0013] The utility model provides a guardrail auxiliary transportation device with a rational structural design. Compared with the existing transportation devices and transportation methods, the guardrail auxiliary transportation device in the utility model is an auxiliary device specially used for transporting guardrails (fragile materials such as marble). During the transportation process, the guardrails are transferred and transported in an upright rather than stacked and leaning posture, and the tops of the guardrails are separated and limited by adjacent separation and limiting components. Therefore, during the transportation process, the guardrails are well limited and protected, and the problem of guardrail collisions caused by factors such as bumps is effectively avoided.

[0014] The guardrail auxiliary transport device of the present invention allows the guardrail to be loaded upon shipment, and the auxiliary transport device can be hoisted and transferred as a whole to a transport vehicle. After arriving at the construction site, the auxiliary transport device and guardrail can also be unloaded as a whole to the material yard, significantly improving the efficiency of guardrail loading and unloading. During guardrail installation, the auxiliary transport device and guardrail can be moved as a whole using a crane installed on-site. Compared to manually transferring guardrails one by one using machinery, the auxiliary transport device improves guardrail construction efficiency at the installation site by facilitating the transfer and access of guardrails. Furthermore, since the guardrails are in a vertical position on the auxiliary transport device, they can be easily accessed individually. Since the guardrails no longer need to be adjusted during installation, installation efficiency is improved and the risks associated with manual operation are reduced to a certain extent.

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0020] See Figure 1 and Figure 2The guardrail auxiliary transport device of the present invention includes two end brackets 1 arranged opposite each other, a supporting beam 9 installed between the lower portions of the two end brackets 1, and two parallel slide rail beams 7 installed between the upper portions of the two end brackets 1. The two end brackets 1, the supporting beam 9, and the slide rail beams 7 together form a rigid frame structure, and multiple guardrails 10 are loaded onto this rigid frame structure. During transfer and transportation, the rigid frame structure and the multiple guardrails 10 are shifted as a whole.

[0021] A support base plate 8 is fixedly mounted on the supporting crossbeam 9, and a plurality of spacer and stopper assemblies 6 are axially mounted on the sliding crossbeam 7. A guardrail 10 is placed on the support base plate 8, positioned between adjacent spacer and stopper assemblies 6, with the tops of the guardrails 10 spaced and stopped by adjacent spacer and stopper assemblies 6. The support base plate 8 provides a stable support platform, and the spacer and stopper assemblies 6 separate and stop the guardrails 10. Therefore, during transfer and transportation, the guardrails 10 do not shift arbitrarily, thus preventing collisions. Furthermore, the guardrails 10 remain upright between adjacent spacer and stopper assemblies 6, facilitating loading and unloading.

[0022] In this embodiment, the end bracket 1 is in the shape of a "M". Specifically: the end bracket 1 includes a middle longitudinal beam 1-1, a bottom connecting plate 1-2 is welded and installed at the bottom of the middle longitudinal beam 1-1, and a top connecting plate 1-5 is welded and installed at the top. A lower diagonal bracing beam 1-3 is welded and installed between the lower part of the middle longitudinal beam 1-1 and the bottom connecting plate 1-2, an upper diagonal bracing beam 1-4 is welded and installed between the upper part of the middle longitudinal beam 1-1 and the top connecting plate 1-5, and a reinforcing connecting beam 1-6 is welded and installed between the lower diagonal bracing beam 1-3 and the upper diagonal bracing beam 1-4 on the same side. The reinforcing connecting beam 1-6 is used to enhance the overall structural strength of the end bracket 1.

[0023] The bottom connecting plate 1-2 of the end bracket 1 forms the bottom plane. When the guardrail 10 is loaded onto the auxiliary transport device, a crane is used to lift the auxiliary transport device and the guardrail 10 loaded thereon to the transport vehicle's cargo bed, with the bottom connecting plate 1-2 resting on the cargo bed. To prevent rigid collision and compression between the bottom connecting plate 1-2 and the cargo bed, sleepers can be placed on the cargo bed, with the bottom connecting plate 1-2 resting on the sleepers.

[0024] One end of the support beam 9 is welded to the lower portion of the middle longitudinal beam 1-1 of the left end bracket 1, and the other end is welded to the lower portion of the middle longitudinal beam 1-1 of the right end bracket 1. The support base plate 8 is a thick steel plate and is welded to the support beam 9. The two slide rail beams 7 have circular cross sections, and the ends of the two slide rail beams 7 are respectively welded to the inner middle portion of the upper diagonal support beam 1-4 of the end bracket 1.

[0025] See Figure 2 , we can see that:

[0026] The separation and limiting assembly 6 includes a translation beam 6-1 with two guide holes in the middle, and two slide rail beams 7 are respectively located in the two guide holes. Translation outer end plates 6-2 are installed at both ends of the translation beam 6-1, and a translation diagonal support beam 6-3 is installed between the lower part of the translation beam 6-1 and the translation outer end plate 6-2.

[0027] The top of the guardrail 10 is located between and is separated and restrained by the translational diagonal bracing beams 6-3 of two adjacent separation and restraining assemblies 6. In this embodiment, to enhance the separation and restraining effect and prevent collision between the guardrail 10 and the auxiliary transport device, a rubber pad is installed on the upper surface of the support base 8 and on both sides of the translational diagonal bracing beams 6-3 of the separation and restraining assemblies 6.

[0028] A top base 4 is installed on the top of each of the two end brackets 1, and a manual limit component 5 is installed on the top base 4 for laterally limiting the partition limit component 6 located on the outermost side. After multiple guardrails 10 are loaded onto the auxiliary transport device, the two manual limit components 5 are operated to move toward the partition limit components 6 on both sides to achieve the effect of limiting the partition limit components 6 on both sides.

[0029] In this embodiment, the manual limiter assembly 5 includes an internally threaded sleeve 5-4 mounted in the middle of the top base 4. A threaded rod 5-2 is disposed within the sleeve 5-4. A limit plate 5-1 is mounted on the inner end of the threaded rod 5-2, and a handwheel 5-3 is mounted on the outer end. During operation, the handwheel 5-3 drives the threaded rod 5-2 to rotate, causing the threaded rod 5-2 to shift axially until the limit plate 5-1 abuts against the side of the translating beam 6-1 that separates the limiter assembly 6.

[0030] In this embodiment, a lifting ring 2 is installed on the top of the end bracket 1. Each end bracket 1 is provided with two lifting rings 2 and is fixed to both sides of the top of the middle longitudinal beam 1-1. The purpose of providing the lifting ring 2 is to facilitate connection with the hook of the crane equipment.

[0031] In this embodiment, anchor rings 3 are mounted on the tops of the end brackets 1. Each end bracket 1 has two anchor rings 3, one mounted on each side of the top of the two upper diagonal bracing beams 1-4. The anchor rings 3 facilitate connection to the anchor cable of the transport vehicle. This anchor cable connects the auxiliary transport device to the vehicle's bed, enhancing stability during transport.

[0032] How to use:

[0033] The auxiliary transport device is set up in the prefabrication site of the guardrail 10. According to the width of the guardrail 10, the position of each separation and limit assembly 6 is moved in advance so that the spacing between adjacent separation and limit assemblies 6 is slightly larger than the top width of the guardrail 10. After the guardrail 10 is processed, the guardrail 10 is lifted and placed between adjacent separation and limit assemblies 6 using on-site equipment such as a forklift, and the guardrail 10 is placed in an upright state on the support base plate 8.

[0034] After the loading of the multiple guardrails 10 is completed, the two manual limiting assemblies 5 are manually operated to move the limiting plates 5 - 1 thereof toward the separating limiting assembly 6 until the limiting plates 5 - 1 abut against the side of the translation beam 6 - 1 of the separating limiting assembly 6 ;

[0035] Then, a crane is used to connect the lifting ring 2 and lift the auxiliary transport device and the guardrail 10 loaded thereon as a whole onto the cargo box of the transport vehicle. After being stably placed, the anchor cables configured on the cargo box of the transport vehicle are connected to the anchor rings 3 and each anchor cable is fully tensioned, which can improve the stability of the auxiliary transport device during the movement of the vehicle.
