Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel reinforcement cage transportation technology, and in particular to a trolley for transporting steel reinforcement cages for concrete guardrails. Background Technology
[0002] In the construction of highways, bridges and other infrastructure, concrete guardrails are widely used as an important safety protection facility. The steel frame of the concrete guardrail is its core load-bearing structure. It is usually welded and tied in a prefabrication yard before being transported to the construction area for concrete pouring.
[0003] Currently, for the completed guardrail frames, the transportation within the factory area mainly relies on the following two methods:
[0004] Manual handling: For smaller or lighter guardrail frames, multiple workers typically work together to lift and move them. This method has significant drawbacks: First, it is extremely labor-intensive, has low productivity, and is heavily reliant on manpower; second, manual handling carries high safety risks, such as bumps and injuries.
[0005] General-purpose lifting equipment with simple lifting tools: For larger and heavier guardrail frames, forklifts or overhead cranes are commonly used with wire ropes for lifting. While this method reduces some of the manpower burden, it also presents several problems. These include: poor flexibility: Forklifts and overhead cranes require relatively open and flat areas to operate, making them inconvenient to move in confined or compact prefabrication yards; low efficiency: Each lifting operation requires a series of operations including hooking, positioning, lifting, moving, lowering, and unhooking, making the process cumbersome and inefficient; poor stability and safety: Guardrail frames are long, narrow, and less rigid mesh structures, making them prone to irreversible plastic deformation due to swaying during lifting. The pressure from the wire ropes can also cause loosening of frame joints or displacement of reinforcing bars, affecting product quality; and high cost: Reliance on large equipment results in higher operating and maintenance costs and energy consumption.
[0006] Therefore, we propose a concrete guardrail steel reinforcement cage transport vehicle to solve the above problems. Utility Model Content
[0007] The purpose of this utility model is to solve the problems existing in the prior art, and a concrete guardrail steel reinforcement skeleton transport trolley is proposed.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A concrete guardrail steel reinforcement frame transport trolley includes a crossbeam, one end of which is fixed with a first hook and the other end of which is fixed with a handle. A frame is provided between the first hook and the handle and is installed on the crossbeam. A second hook is provided between the frame and the handle.
[0010] The frame includes a support frame, which is in the shape of an inverted U.
[0011] Preferably, the handrail is in the shape of an inverted T and is located below the crossbeam.
[0012] Preferably, the second hook includes a hanging ring, which is sleeved on the crossbeam, and a first protrusion is fixed on the crossbeam, the first protrusion being able to abut against the hanging ring.
[0013] Preferably, both the first hook and the second hook are provided with bent hooks, the bent hooks of the first hook and the bent hooks of the second hook are arranged facing each other, and both the first hook and the second hook are located below the crossbeam.
[0014] Preferably, the support frame is arranged perpendicular to the crossbeam, the support frame is fixedly connected to the crossbeam, and multiple reinforcing ribs are fixed between the support frame and the crossbeam.
[0015] Preferably, wheels are mounted on both ends of the bottom of the support frame via bearings, and a crossbeam is horizontally positioned between the two wheels, with the crossbeam and the top of the support frame arranged in a cross shape.
[0016] Preferably, the crossbeam further includes an intermediate sleeve rod, the support frame is mounted on the intermediate sleeve rod, and the two ends of the intermediate sleeve rod are respectively telescopically mounted with a front telescopic rod and a rear telescopic rod.
[0017] Preferably, the first hook is fixedly connected to the end face of the front telescopic rod, the handle is fixedly connected to the end face of the rear telescopic rod, the hanging ring of the second hook is sleeved on the rear telescopic rod, and a second protrusion is fixed on the rear telescopic rod, the second protrusion being able to abut against the hanging ring.
[0018] Preferably, the front telescopic rod and the rear telescopic rod can be locked to the intermediate sleeve rod by a pin. Both the front telescopic rod and the rear telescopic rod are provided with several through holes at equal intervals. Both ends of the intermediate sleeve rod are provided with two through holes. The two through holes at one end can be used to insert the pin, and the pin can pass through the through holes.
[0019] Preferably, one end of the pin is fixed with a stop block, and the other end of the pin is provided with a round hole, which can dampen the insertion of the positioning pin rod.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This invention only requires hoisting the concrete guardrail steel frame onto the crossbeam, after which one person can easily push it, eliminating the tedious process of multiple people coordinating lifting or frequently operating lifting equipment. This greatly improves the convenience and efficiency of transportation. At the same time, it can move freely in narrow or complex passages in the prefabrication yard, solving the problems of inconvenient turning of large equipment (such as forklifts) and high site requirements. It achieves precise "point-to-point" transportation, significantly shortens the single transportation cycle, improves the overall efficiency of the production line, and reduces direct contact between workers and heavy objects, avoiding workplace accidents such as bumps and crushing injuries. It significantly reduces labor intensity and safety risks, resulting in a fundamental improvement in safety. Attached Figure Description

[0032] Example 1
[0033] Reference Figures 1-3 A concrete guardrail steel frame transport trolley includes a crossbeam, one end of which is fixed with a first hook 1 and the other end of which is fixed with a handle 2. A frame is provided between the first hook 1 and the handle 2 and installed on the crossbeam. A second hook 3 is provided between the frame and the handle 2.
[0034] The frame includes a support frame 4, which is inverted U-shaped. Figure 1 and Figure 2 As shown, the crossbeam can be made of cylindrical steel pipe. The crossbeam and the support frame 4 work together to achieve a lever effect, that is, the support frame 4 serves as the fulcrum. The crossbeam can be controlled by the handle 2, and when not in use, the handle 2 can rest against the ground to support the entire crossbeam.
[0035] The length of the crossbeam can be set such that the height of the first hook 1 and the second hook 3 is 0.2m, and the height of the handle 2 is 0.3m.
[0036] Handrail 2 is in the shape of an inverted T and is located below the crossbeam.
[0037] The second hook 3 includes a hanging ring 5, which is sleeved on the crossbeam. A first protrusion 6 is fixed on the crossbeam and can abut against the hanging ring 5. When not in use, when the handle 2 is against the ground, the end of the crossbeam closest to the handle 2 is close to the ground and its height is lower than the other end. At this time, the first protrusion 6 acts to abut against the hanging ring 5, which can prevent the second hook 3 from slipping off.
[0038] Both the first hook 1 and the second hook 3 are equipped with bent hooks. The bent hooks of the first hook 1 and the second hook 3 are arranged facing each other. Both the first hook 1 and the second hook 3 are located below the crossbeam.
[0039] Both the first hook 1 and the second hook 3 have bent hooks used to hook onto the concrete guardrail reinforcement skeleton. The hooking method involves pushing the crossbeam with the handle 2 to move it, making the crossbeam parallel to the concrete guardrail reinforcement skeleton, with the reinforcement skeleton located at the bottom of the support frame 4. Then, the front end of the crossbeam is lowered using the handle 2, bringing the first hook 1 close to the concrete guardrail reinforcement skeleton to be hooked. The first hook 1 is then hooked onto one end of the reinforcement skeleton. Next, the rear end of the crossbeam is pressed down, bringing the second hook 3 close to the reinforcement skeleton to be hooked. The second hook 3 is then hooked onto the other end of the reinforcement skeleton. Finally, the crossbeam is raised until it is parallel to the reinforcement skeleton. At this point, the first hook 1 and the second hook 3 lift the reinforcement skeleton. Moving the crossbeam with the handle 2 allows for the transport of the concrete guardrail reinforcement skeleton.
[0040] The support frame 4 is perpendicular to the crossbeam and is fixedly connected to the crossbeam. Multiple reinforcing ribs 7 are also fixed between the support frame 4 and the crossbeam. These reinforcing ribs 7 increase the overall strength.
[0041] Wheels 8 are mounted on both ends of the bottom of the support frame 4 via bearings. A crossbeam is positioned laterally between the two wheels 8, and the crossbeam is arranged in a cross shape with the top of the support frame 4. The bottom of the support frame 4 provides sufficient space, such as... Figure 3 As shown. With the above setup, the concrete guardrail reinforcement cage can be horizontally positioned below the support frame 4, parallel and aligned with the crossbeam. After the first hook 1 and the second hook 3 hook the concrete guardrail reinforcement cage, the crossbeam can be controlled and pushed via the handle 2 to move it. At this time, the crossbeam is parallel and corresponding to the concrete guardrail reinforcement cage, and there is a distance between it and the ground, thus achieving the effect of moving the concrete guardrail reinforcement cage. Daily maintenance of the above components only requires attention to easily damaged parts such as the wheels 8 and bearings, resulting in extremely low maintenance costs.
[0042] The concrete guardrail reinforcement cage is 4m high and 1.2m long, with a trapezoidal end face shape. The height and width dimensions of the concrete guardrail reinforcement cage are not limited to one type. The height of the support frame 4 plus the wheels 8 can reach 1.6m. The height and bottom space of the support frame 4 are sufficient to accommodate the concrete guardrail reinforcement cage for transport at its base.
[0043] In this invention, the working principle of the device is as follows:
[0044] By pushing the crossbeam with handle 2, the crossbeam is moved parallel to the concrete guardrail reinforcement skeleton, with the concrete guardrail reinforcement skeleton located at the bottom of the support frame 4. Then, the front end of the crossbeam is lowered using handle 2, bringing the first hook 1 close to the concrete guardrail reinforcement skeleton to be hooked. The first hook 1 is then hooked onto one end of the concrete guardrail reinforcement skeleton. Next, the rear end of the crossbeam is pressed down, bringing the second hook 3 close to the concrete guardrail reinforcement skeleton to be hooked. The second hook 3 is then hooked onto the other end of the concrete guardrail reinforcement skeleton. The crossbeam is then raised until it is parallel to the concrete guardrail reinforcement skeleton. At this point, the first hook 1 and the second hook 3 lift the concrete guardrail reinforcement skeleton. Moving the crossbeam with handle 2 allows for the movement and transportation of the concrete guardrail reinforcement skeleton.
[0045] Example 2
[0046] Reference Figures 4-6 The difference between this embodiment and Embodiment 1 is that:
[0047] The crossbeam also includes a central sleeve rod 9, on which the support frame 4 is mounted. A front telescopic rod 10 and a rear telescopic rod 11 are slidably mounted at both ends of the central sleeve rod 9. The front telescopic rod 10 and the rear telescopic rod 11 can be telescopically extended or shortened, thus achieving the effect of lengthening or shortening the entire crossbeam. The front telescopic rod 10 and the rear telescopic rod 11 are as follows... Figure 4 and Figure 5 As shown.
[0048] The first hook 1 is fixedly connected to the end face of the front telescopic rod 10, and the handle 2 is fixedly connected to the end face of the rear telescopic rod 11. The hanging ring 5 of the second hook 3 is sleeved on the rear telescopic rod 11, and a second protrusion 12 is fixed on the rear telescopic rod 11, which can abut against the hanging ring 5. The telescopic movement of the front telescopic rod 10 and the rear telescopic rod 11 can respectively drive the movement of the first hook 1 and the second hook 3.
[0049] The support frame 4, the first hook 1, and the second hook 3 are used in the same way as in Embodiment 1.
[0050] The front telescopic rod 10 and the rear telescopic rod 11 can be locked to the intermediate sleeve rod 9 by means of a pin 15. Both the front telescopic rod 10 and the rear telescopic rod 11 have several equally spaced through holes 13. Two through holes 14 are provided at both ends of the intermediate sleeve rod 9. The two through holes 14 at one end can accommodate the pin 15, and the pin 15 can pass through the through holes 13. A stop block 18 is fixed to one end of the pin 15, and a round hole 16 is provided at the other end of the pin 15. The round hole 16 can dampen the insertion of the positioning pin 17, as detailed below. Figure 6As shown. The telescopic movement of the front telescopic rod 10 and the rear telescopic rod 11 allows for selection of the telescopic length, which is determined by the number of through holes 13. When adjusting the telescopic movement of the front telescopic rod 10 and the rear telescopic rod 11, it is necessary to ensure that the corresponding through hole 13 is aligned with the through hole 14 at the end of the intermediate sleeve rod 9. Then, by inserting a pin 15 and damping the insertion of a positioning pin 17 on the pin 15, the pin 15 can be positioned on the intermediate sleeve rod 9, allowing the intermediate sleeve rod 9 to be locked and connected to either the front telescopic rod 10 or the rear telescopic rod 11.
[0051] Furthermore, the above example is not limited to setting a positioning pin 17. The positioning pin 17 can also be replaced with a threaded rod, and the round hole 16 can be replaced with a threaded hole. The threaded rod is screwed into the threaded hole to achieve the effect of positioning pin 15.
[0052] The working principle is as follows:
[0053] When the dimensions of the concrete guardrail reinforcement cage change, the length of the entire crossbeam can be extended or shortened by adjusting the front telescopic bar 10 and the rear telescopic bar 11. The extension and retraction of the front telescopic bar 10 and the rear telescopic bar 11 respectively move the first hook 1 and the second hook 3, thus adjusting their positions. This allows for the hooking and subsequent convenient handling of concrete guardrail reinforcement cages of various lengths. It should be noted that the adjustment of the front telescopic bar 10 and the rear telescopic bar 11 only accommodates the handling of concrete guardrail reinforcement cages of different specifications within a specified range. The hooking method is the same as in Example 1.
[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
