Description

Technical Field

[0001] This application relates to the field of reinforced concrete pipeline transportation technology, and in particular to a support for transporting reinforced concrete pipelines using a backhoe excavator. Background Technology

[0002] During the construction of municipal pipeline projects, cranes are generally used to lift and install reinforced concrete pipes. After the pipes are loaded onto trucks and transported to the site, each section of pipe needs to be unloaded and installed by a dedicated person who secures the lifting equipment to the pipe before lifting. Each section of pipe needs to be lifted at least once. The cumbersome on-site operation results in a long time consumption, which affects the on-site construction progress. Utility Model Content

[0003] To address or partially address the problems existing in the related technologies, this application provides a support for transporting reinforced concrete pipes using a backhoe excavator.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A support for transporting reinforced concrete pipes using a backhoe excavator, the support comprising:

[0006] Two main trusses are set in parallel. The length of the main truss is fixed to the excavator's stick at one end and a triangular hook is connected to the other end.

[0007] The main truss and the boom have a 65° angle, so that the main truss, boom, triangular hook and excavator bucket together form a mechanical claw for clamping reinforced concrete pipes. The excavator bucket rotates to adjust the clamping force of the mechanical claw.

[0008] Optionally, at least one connecting rod is provided between the two main trusses.

[0009] Optionally, a first support rod and a second support rod are provided between the main truss and the boom;

[0010] The first support rod is located at the end of the main truss beam near the boom, and the second support rod is located at the end of the main truss beam near the triangular hook.

[0011] Optionally, rubber pads are attached to the main truss, the triangular hook, and the excavator bucket.

[0012] Optionally, the first support rod has an angle A of 50° with the main truss, and the second support rod has an angle B of 25° with the main truss.

[0013] Optionally, the triangular hook includes two diagonal bars, which have angles C of 150° and angle D of 130° with the main truss, respectively.

[0014] Optionally, the main truss beam is a steel plate with a length of 1.2m, a width of 5cm, and a thickness of 20mm.

[0015] Optionally, the connecting rod, the first support rod, the second support rod, and the diagonal rod are made of threaded steel.

[0016] The beneficial effects of this application are as follows: This application utilizes the 180° free movement of the bucket of a backhoe excavator, and welds a bracket at the rear of the bucket's boom to form a mechanical claw with the bucket. The mechanical claw grabs and fixes the reinforced concrete pipe. After grabbing the pipe, the excavator can move freely and place the pipe in the designated location. This replaces the traditional method of unloading and installing reinforced concrete pipes by lifting and hoisting with a crane, reducing on-site operation steps, shortening operation time, and ensuring that the on-site construction progress is not affected.

[0030] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0031] Example 1:

[0032] See Figure 1 and Figure 2 A support for transporting reinforced concrete pipes using a backhoe excavator, the support comprising:

[0033] Two parallel main trusses 1 are fixed at one end of the length of the main trusses 1 to the excavator boom 2, and the other end is connected to a triangular hook 3.

[0034] The main truss 1 and the boom 2 have a 65° angle between them, so that the main truss 1, boom 2, triangular hook 3 and excavator bucket together form a mechanical claw for clamping reinforced concrete pipes. The excavator bucket can be rotated to adjust the clamping force of the mechanical claw.

[0035] Specifically, the main truss 1 is welded to the excavator boom 2 at one end along its length, with the welding point 80cm away from the hinge point between the excavator bucket and boom 2. The two main trusses 1 are spaced 40cm apart. Using two main trusses 1 enhances structural strength and increases clamping force, thereby improving clamping stability. The bottoms of the two inclined sides of the triangular hook 3 are welded to the other end along the length of the main truss 1. The main truss 1 and boom 2 have a 65° angle, so that the main truss 1, boom 2, triangular hook 3, and excavator bucket together form a mechanical claw for clamping reinforced concrete pipes. By rotating the excavator bucket, the clamping size is changed, thereby adjusting the clamping force of the mechanical claw, thus enabling the gripping or unloading of the reinforced concrete pipes.

[0036] This application utilizes the 180° free movement of the bucket of a backhoe excavator, welding brackets at two points on the boom behind the bucket to form a mechanical claw. The mechanical claw grips and fixes the reinforced concrete pipe. After gripping the pipe, the excavator can move freely to place the pipe in the designated location. This replaces the traditional method of unloading and installing reinforced concrete pipes by lifting and hoisting with a crane, reducing on-site operation steps, shortening operation time, and ensuring that the on-site construction progress is not affected.

[0037] In addition, by installing a bracket at the boom 2 of the excavator, the bucket is modified into a mechanical claw structure, which can be widely used for loading and unloading reinforced concrete pipes of different diameters. The process does not require manual assistance for multiple lifting operations, which improves work efficiency, reduces cost input, and enhances safety performance.

[0038] Example 2:

[0039] See Figure 2 and Figure 3 Based on Embodiment 1, optionally, at least one connecting rod 4 is provided between the two main trusses 1.

[0040] Specifically, the connecting rod 4 is welded to one of the main trusses 1 at one end and to the other main truss 1 at the other end. The connecting rod 4 enhances the integrity of the two main trusses 1, thereby increasing structural strength and rigidity, ensuring the performance of the support system, and extending its service life. In this embodiment, three connecting rods 4 are evenly spaced, effectively enhancing the strength and rigidity of the support system. The interval between adjacent connecting rods 4 is 40cm.

[0041] Optionally, a first support rod 5 and a second support rod 6 are provided between the main truss beam 1 and the boom 2;

[0042] Among them, the first support rod 5 is located at the end of the main truss beam 1 near the stick 2, and the second support rod 6 is located at the end of the main truss beam 1 near the triangular hook 3.

[0043] Specifically, one end of the first support rod 5 and the second support rod 6 are welded to the main truss beam 1, and the other end is welded to the boom 2. Since there are two main truss beams 1, two first support rods 5 and two second support rods 6 are also provided accordingly. The first support rods 5 and the second support rods 6 can provide additional support for the two main truss beams 1, thereby enhancing the reliability of the main truss beams 1.

[0044] Optionally, rubber pads are attached to the main truss 1, the triangular hook 3, and the excavator bucket.

[0045] Specifically, the rubber pads are 10mm thick. By binding the rubber pads to the main truss beam 1, the triangular hook 3 and the excavator bucket, slippage or damage to the outer surface of the pipe is prevented at the contact points between the support and the reinforced concrete pipe.

[0046] Optionally, the first support rod 5 has an angle A of 50° with the main truss beam 1, and the second support rod 6 has an angle B of 25° with the main truss beam 1.

[0047] Specifically, the angles between the first support rod 5 and the main truss 1, and between the second support rod 6 and the main truss 1, are selected according to the actual situation.

[0048] Optionally, the triangular hook 3 includes two diagonal bars, which have angles C of 150° and angles D of 130° with the main truss beam 1, respectively.

[0049] Specifically, since there are two main truss beams 1, there are also two corresponding triangular hooks 3. The two triangular hooks 3 are connected by a crossbar to enhance the structural strength. The angle between the two diagonal bars of the triangular hook 3 and the main truss beam 1 is selected according to the actual situation.

[0050] Optionally, the main truss beam 1 is a steel plate with a length of 1.2m, a width of 5cm, and a thickness of 20mm.

[0051] Specifically, the main truss beam 1 is made of steel plate, which is convenient for welding triangular hooks 3, connecting rods 4, first support rods 5 and second support rods 6. The 5cm wide and 20mm thick steel plate can ensure sufficient strength.

[0052] Optionally, the connecting rod 4, the first support rod 5, the second support rod 6, and the diagonal rod are made of threaded steel.

[0053] Specifically, connecting rod 4, first support rod 5, second support rod 6, and diagonal rod are made of HRB400 threaded steel with a diameter of φ20. HRB400 threaded steel has high tensile strength and yield point, enabling it to withstand large loads and deformations, thereby improving structural safety. HRB400 threaded steel also has high hardness, good wear resistance, and is not easily deformed, maintaining good shape and dimensional stability during long-term use, thus extending its service life. Furthermore, HRB400 threaded steel has good weldability and machinability, facilitating construction. In addition, compared to other types of steel, HRB400 threaded steel is relatively inexpensive, offering high cost-effectiveness.

[0054] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0055] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
