Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar movement, and in particular relates to a device for facilitating the transportation of steel bars. Background Art

[0002] Steel bars are often used in construction and are very common on construction sites. When used, the steel bars on the construction site often need to be moved to the required location. The traditional way of moving them is to use manual or flatbed trucks. Manual moving is time-consuming, labor-intensive and inefficient. At the same time, since most steel bars are long, the stability of the steel bars on the flatbed trucks is poor and they are easy to fall, causing danger. Especially for steel bars of more than ten meters or even dozens of meters, it is more inconvenient to use traditional moving methods.

[0003] The patent document with publication number CN218750828U discloses a steel bar handling device, including a base, four rectangularly distributed first electric push rods are fixedly connected to the upper end of the base, a shell is fixedly connected between the telescopic ends of the four first electric push rods, two symmetrically arranged moving plates are slidably connected inside the shell, the side walls of the two moving plates are fixedly connected with sliding rods, the two sliding rods pass through the two end side walls of the shell respectively and are slidably connected thereto, the ends of the two sliding rods located outside the shell are fixedly sleeved with sleeves, the upper ends of the two sleeves are fixedly connected with fixed frames, the two fixed frames are provided with clamping mechanisms for clamping products, the shell is provided with a moving mechanism for moving the fixed frame, the moving mechanism includes a double-headed threaded rod rotatably connected between the inner side walls at both ends of the shell, the double-headed threaded rod passes through the two moving plates and is threadedly connected thereto;

[0004] When in use, the output shaft of the driving motor rotates, driving the double-headed threaded rod to rotate, thereby driving the two movable plates threadedly connected thereto to move, driving the two sliding rods and the sleeve to move, driving the fixed frame and the clamping mechanism to move. After moving to a suitable position, the steel bar is placed between the two fixed frames to adjust the spacing between the two fixed frames, thereby facilitating the transportation of steel bars of different lengths. After the steel bar is placed between the two fixed frames, the telescopic end of the second electric push rod is driven to extend, driving the support plate to move downward, so that the support plate is pressed against the steel bar to clamp the steel bar, thereby improving the stability during the steel bar transportation process.

[0005] However, the following problems still exist in the actual handling process using the steel bar handling device:

[0006] (1) Steel bars are usually transported in bundles. When using the above-mentioned transport device, the steel bars need to be manually moved up to a certain height and then inserted between two fixed frames for fixing and transportation. The use of this device is time-consuming and laborious when loading and unloading steel bars. In addition, the space in the fixed frame is limited and many steel bars cannot be placed. If the fixed frame is designed to be larger, it will affect transportation and storage.

[0007] (2) There is no device to assist workers in loading and unloading steel bars. Loading and unloading can only be done by manpower or other related equipment, which increases the labor intensity and cost of workers and is not conducive to practical use.

[0008] Therefore, it is urgent to design a device that is convenient for steel bar transportation to solve the above problems, reduce the labor intensity of workers and improve work efficiency. Utility Model Content

[0009] In view of the above-mentioned existing steel bar handling device, during use, no device is set to assist workers in loading and unloading steel bars, which is not conducive to practical use. At the same time, when using the device for transportation, the steel bars need to be manually moved up to a certain height and then stuffed between two fixed frames before they can be fixed and transported, which is time-consuming and labor-intensive. In addition, the space in the fixed frame is limited and cannot accommodate more steel bars. Enlarging the fixed frame is not conducive to transportation and storage. The purpose of the utility model is to provide a device that is convenient for steel bar transportation, including a steel bar loading carrier, a roller assembly is provided at the lower end of the steel bar loading carrier, a handrail and an extension are provided at the rear end, and an auxiliary mechanism is provided at the front end. The roller assembly and the handrail can facilitate workers to move the device, the extension can lengthen the length of the steel bar loading carrier to accommodate steel bars of a larger length, and the auxiliary mechanism can assist workers in loading and unloading steel bars, thereby reducing the labor intensity of workers.

[0010] The core technical idea of ​​the utility model is: in order to solve the problem of transporting steel bars of different lengths, the steel bar loading body is set to a double-layer structure. Under normal circumstances, the extension piece is set in the steel bar loading body in a drawer-like manner. When the length of the steel bar is longer than the length of the steel bar loading body, the extension piece can be pulled out to increase its length, which is convenient for transporting the longer steel bars. The horizontal height of the extension piece is lower than the horizontal height of the steel bar loading body, forming a height difference. The longer steel bars are placed on the steel bar loading body and the extension piece, which is more conducive to their stable placement. The auxiliary mechanism uses the roller principle to assist and limit the steel bars placed on the steel bar loading body, which is convenient for loading and unloading and transportation.

[0011] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0012] A device for facilitating the transport of steel bars comprises a steel bar loading body, a roller assembly is arranged at the lower end of the steel bar loading body, an auxiliary mechanism is adaptively connected to the front end of the steel bar loading body, and an extension piece is slidably arranged at the rear end.

[0013] Preferably, the auxiliary mechanism includes:

[0014] The outer shell is obliquely connected to the front end of the steel bar loading body;

[0015] A loading and unloading auxiliary component is rotatably arranged in the housing;

[0016] The limiting component is movably arranged on the shell and is staggered with the loading and unloading auxiliary components.

[0019] Preferably, the moving parts include:

[0020] A motor is fixed on the inner wall of the housing;

[0021] A cam connected to the motor;

[0022] A limiting sleeve, fixedly arranged on the inner wall of the shell;

[0023] The connecting rod has one end passing through the limiting sleeve and eccentrically connected to the cam, and the other end rotatably connected to the limiting rotating shaft assembly.

[0024] The movable rod has one end rotatably connected to the cam and the other end rotatably connected to the connecting rod.

[0025] Preferably, the position-limiting rotating shaft assembly comprises a rotating shaft group and a supporting member connected to each other, and the supporting member is connected to the moving component.

[0026] Preferably, the rotating shaft group includes a plurality of limiting rotating shafts, and a plurality of limiting protrusions are arranged on the surface of the limiting rotating shafts, and the plurality of limiting protrusions are triangular plate structures with an arc.

[0029] The beneficial effects of the utility model are as follows: the utility model discloses a device for facilitating the transportation of steel bars. Compared with the prior art, the improvements of the utility model are as follows:

[0030] (1) The utility model is designed with an auxiliary mechanism, which consists of an outer shell, a loading and unloading auxiliary component and a limiting component arranged in the outer shell. The outer shell is connected to a steel bar loading body. The loading and unloading auxiliary component facilitates workers to put steel bars into and take out steel bars from the steel bar loading body when loading and unloading steel bars, thereby reducing the labor intensity of workers. Meanwhile, during transportation, the limiting component limits the steel bars placed in the steel bar loading body to prevent the steel bars from falling out of the steel bar loading body due to transportation or shaking.

[0031] (2) The utility model is designed with an extension piece, which is slidably mounted in the steel bar loading body. When it is necessary to transport longer steel bars, the extension piece is pulled out to increase the length of the steel bar loading body. At this time, a height difference is formed between the extension piece and the steel bar loading body in the horizontal direction, so that when the steel bars are placed, the stiffness of the steel bars at the front and rear is inconsistent, thereby playing a certain limiting role on the steel bars.

[0032] (3) The utility model provides a fixing assembly on the steel bar loading body and the extension piece. The fixing assembly may be one or more. The main function of the fixing assembly is to fix the steel bar loading body and the extension piece to prevent the extension piece from slipping into the steel bar loading body during use, thereby affecting the transportation of the steel bars.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0044] Example 1

[0045] See attached Figure 1 As shown, a device for facilitating the transport of steel bars comprises a steel bar carrier 1. Preferably, the steel bar carrier 1 is a U-shaped structure. Fig. 9 As shown, this arrangement is convenient for limiting the position of the steel bars placed in the steel bar loading carrier 1 on both sides for easy transportation. A roller assembly 3 is provided at the lower end of the steel bar loading carrier 1 to facilitate the movement of the steel bar loading carrier 1; an extension piece 101 is provided on the sliding sleeve at the rear end of the steel bar loading carrier 1, and a height difference is formed between the extension piece 101 and the steel bar loading carrier 1 in the horizontal direction, which is convenient for the transportation and limiting of longer steel bars;

[0046] Preferably, the extension piece 101 is a plate-like structure, which can be an extension plate, which is similar to a drawer-style sliding sleeve arranged in the mobile steel bar loading body 1. When in use, the extension piece 101 can be pulled out of the mobile steel bar loading body 1, and when not in use, the extension piece 101 can be slid and pushed into the mobile steel bar loading body. The structure of the extension piece 101 slidingly arranged in the steel bar loading body 1 can be the same as the existing drawer sliding structure, or it can be the existing setting mode of the slider and the slide groove, and finally the extension piece 101 can be slidable in and out of the mobile steel bar loading body 1;

[0047] The rebar loading carrier 1 is detachably provided with a U-shaped handle 5 at one end close to the extension piece 101, so that workers can push and pull the rebar loading carrier 1 through the U-shaped handle 5. Specifically, the rebar loading carrier 1 is provided with a screw hole 1, and the U-shaped handle 5 is provided with a screw hole 2, and then the bolt is passed through the screw hole 2 to the screw hole 1 to complete the detachable connection between the U-shaped handle 5 and the rebar loading carrier 1.

[0048] The use process and principle of the device for facilitating the transportation of steel bars in the preferred embodiment are as follows: first, the U-shaped handle is removed, and then the steel bars are placed in the steel bar loading carrier 1. When the length of the steel bars to be transported is long, the extension piece 101 can be pulled out to increase the length of the steel bar loading carrier 1, thereby preventing the two ends of the steel bars from contacting the ground after the steel bars are placed on the steel bar loading carrier 1, which is not conducive to transportation. Finally, the U-shaped handle 5 is installed on the steel bar loading carrier 1, and the worker can use the U-shaped handle 5 to transport the steel bars in the steel bar loading carrier 1 to the required position.

[0049] Embodiment 2:

[0050] The difference between Example 2 and Example 1 is that, based on Example 1, considering that when carrying the steel bars into the steel bar loading carrier 1, the workers need to lift the steel bars to a height higher than the steel bar loading carrier 1, which is time-consuming and laborious, and is a great consumption of the workers' physical strength, therefore, in this embodiment, an auxiliary mechanism 4 is provided at the front end of the steel bar loading carrier 1, which can assist the workers in loading and unloading the steel bars in the steel bar loading carrier 1;

[0051] See attached Figure 1 As shown, the front end of the steel bar loading body 1 is adapted to be connected with an auxiliary mechanism 4, which can assist workers in transferring the steel bars in the steel bar loading body without hindering the movement of the steel bar loading body 1;

[0052] See attached Figure 2 As shown, the auxiliary mechanism 4 includes a shell 401, a loading and unloading auxiliary component 402 and a limiting component 403. The shell 401 is adaptively connected to the front end of the steel bar loading body 1. Preferably, the shell 401 is a triangular structure, which forms a slope with the ground to facilitate the auxiliary workers to load and unload the steel bars; the loading and unloading auxiliary component 402 and the limiting component 403 are movably and staggeredly installed in the shell 401, and the loading and unloading auxiliary component 402 and the limiting component 403 are adapted, that is, the loading and unloading auxiliary component 402 will not affect the up and down movement of the limiting component 403;

[0053] See attached Figure 3 As shown, the loading and unloading auxiliary assembly 402 includes a plurality of rotating shafts 402-1 and mounting seats 402-2. The rotating shafts 402-1 are rotatably mounted in the housing 401 through the mounting seats 402-2 and are adapted to the limiting assembly 403, that is, the rotating shafts 402-1 will not affect the limiting assembly 403 passing through the gap between the two rotating shafts 402-1. Preferably, the rotating shafts 402-1 are cylindrical in structure and have a smooth surface; the rotating shafts 402-1 are arranged in a stepped structure in the housing 401;

[0054] The position limiting assembly 403 includes a movable part 403-1 and a position limiting shaft assembly 403-2 which are connected to each other. The movable part 403-1 is arranged on the inner side wall of the housing 401, and the position limiting shaft assembly 403-2 is movably arranged in the housing 401 and is adapted to the loading and unloading auxiliary assembly 402. In a normal state, the position limiting shaft assembly 403-2 is directly below the loading and unloading auxiliary assembly 402. When the steel bar needs to be limited, the movable part 403-1 drives the position limiting shaft assembly 403-2 to move upward and pass through the loading and unloading auxiliary assembly 402, and finally exceeds the horizontal height of the loading and unloading auxiliary assembly 402, so that the steel bar is separated from the loading and unloading auxiliary assembly 402 and contacts the position limiting shaft assembly 403-2, thereby limiting the steel bar.

[0055] Specific reference Figure 4 and 7 As shown, the moving component 403-1 includes a motor 403-1A, a cam 403-1B, a connecting rod 403-1C, a limiting sleeve 403-1D and a movable rod 403-1E. The motor 403-1A is fixed on the inner wall of the housing 401. The cam 403-1B is connected to the output end of the motor 403-1A. One end of the movable rod 403-1E is eccentrically connected to the cam 403-1B and is rotatably connected, and the other end is rotatably connected to the connecting rod 403-1C. The connecting rod 403-1C passes through the limiting sleeve 403-1D, and the other end of the connecting rod 403-1C is fixedly connected to the limiting rotating shaft assembly 403-2. The limiting sleeve 403-1D is fixedly connected to the inner wall of the housing 401. Specifically, the limiting sleeve 403-1D is connected to the inner wall of the housing 401 through the fixed rod.

[0056] When in use, the motor 403-1A is turned on, the motor 403-1A drives the cam 403-1B to rotate, and the cam 403-1B drives the movable rod 403-1E to rotate. Since the movable rod 403-1E is rotatably connected with the cam 403-1B and the connecting rod 403-1C respectively, under the drive of the cam 403-1B and the limiting action of the limiting sleeve 403-1D, the movable rod 403-1E drives the connecting rod 403-1C to move up and down, thereby driving the limiting shaft assembly 403-2 to move up and down;

[0057] For further information, please refer to the attached Figure 5 As shown, the position-limiting rotating shaft assembly 403-2 includes a rotating shaft group 403-2A and a supporting member 403-2B connected to each other. The rotating shaft group 403-2A is arranged in a stepped structure in the housing 401.

[0058] The support member 403-2B is connected to the end of the connecting rod 403-1C in the moving part 403-1; the connecting rod 403-1C moves up and down, driving the support member 403-2B to move up and down, and the support member 403-2B drives the shaft assembly 403-2A to move up and down, and then moves up and down in the gap between the two shafts 402-1;

[0059] And refer to the attached Figure 3 , 5 As shown in FIG. 8 , the shaft group 403-2A includes a plurality of limit shafts 403-2A1, and a plurality of limit protrusions 403-2A2 are provided on the surface of the limit shafts 403-2A1, and the plurality of limit protrusions 403-2A2 are triangular plate structures with arcs, which is similar to providing a "barb" on the surface of the limit shaft 403-2A1, thereby grabbing and pulling the steel bar with a downward movement tendency to prevent it from moving downward;

[0060] The use process and principle of the device for facilitating the transportation of steel bars in this preferred embodiment are as follows: under normal conditions, the limiting rotating shaft assembly 403-2 is directly below the loading and unloading auxiliary assembly 402. When a worker is transporting a steel bar, he drags one end of the steel bar so that the steel bar passes through a plurality of rotating shafts 402-1 arranged in a stepped structure. After the rotating shaft 402-1 contacts the steel bar, it is rotated by the steel bar, thereby assisting the worker in transporting the steel bar to the steel bar loading carrier 1. After the steel bar is placed on the steel bar loading carrier 1, the motor 403-1A is turned on, the motor 403-1A drives the cam 403-1B to rotate, and the cam 403-1B drives the movable rod 403-1E to rotate. Under the limiting action of the limiting sleeve 403-1D, the movable rod 403-1E drives the connecting rod 403-1 C moves up, thereby driving the support member 403-2B to move up, and the support member 403-2B drives the rotating shaft group 403-2A to move up, so that the rotating shaft group 403-2A moves up in the gap between every two rotating shafts 402-1, and passes through the loading and unloading auxiliary component 402, so that the steel bar is separated from the loading and unloading auxiliary component 402 and contacts with the limiting rotating shaft 403-2A1, and the limiting protrusion 403-2A2 thereon is used to grab and limit the steel bar to prevent the steel bar from slipping out of the steel bar loading body 1 during transportation. After arriving at the destination, turn on the motor 403-1A to move the limiting rotating shaft 403-2A1 downward to just below the loading and unloading auxiliary component 402, so that the loading and unloading auxiliary component 402 can assist the workers in unloading the steel bar from the steel bar loading body 1.

[0061] Example 3

[0062] The difference between Example 3 and Example 2 is that, based on Example 2, Figure 1As shown, considering that the extension piece 101 may slide into the steel bar loading carrier 1 during use and transportation, affecting the transportation of the steel bars, a fixing component 2 is provided on the outer side walls of the steel bar loading carrier 1 and the extension piece 101. The fixing component 2 may be provided on one side of the outer side wall or on both sides of the outer side wall, depending on the actual use requirements. The fixing component 2 fixes the steel bar loading carrier 1 and the extension piece 101 to prevent the extension piece 101 from sliding into the steel bar loading carrier 1 and affecting the work efficiency.

[0063] See attached Figure 6 As shown, the fixing assembly 2 includes a matching fixing bar 201 and an L-shaped limiting seat 202. The fixing bar 201 is rotatably set on the outer wall of the steel bar loading body 1, and the L-shaped limiting seat 202 is set on the outer wall of the extension piece 101. When in use, the fixing bar 201 is rotated so that the fixing bar 201 is stuck on the L-shaped limiting seat 202, thereby achieving the fixation of the steel bar loading body 1 and the extension piece 101.

[0064] The use process and principle of the device for facilitating the transport of steel bars of the utility model are as follows: first, the U-shaped handle is disassembled, and the extension piece 101 is pulled out and fixed according to the length of the transported steel bars;

[0065] Then, one end of the steel bar is dragged so that the steel bar passes through a plurality of rotating shafts 402-1 arranged in a stepped structure. After the rotating shaft 402-1 contacts the steel bar, it is rotated by the steel bar, thereby helping the worker to carry the steel bar to the steel bar loading carrier 1. After the steel bar is placed on the steel bar loading carrier 1, the U-shaped handle 5 is installed on the steel bar loading carrier 1, and the motor 403-1A is turned on. The motor 403-1A drives the cam 403-1B to rotate, and the cam 403-1B drives the movable rod 403-1E to rotate. 1D, the movable rod 403-1E drives the connecting rod 403-1C to move upward, and then drives the support member 403-2B to move upward, and the support member 403-2B drives the rotating shaft group 403-2A to move upward, so that the rotating shaft group 403-2A moves in the gap between every two rotating shafts 402-1, and passes through the loading and unloading auxiliary component 402, so that the steel bar is separated from the loading and unloading auxiliary component 402 and contacts with the limiting rotating shaft 403-2A1, and the limiting protrusion 403-2A2 thereon is used to grab and limit the steel bar;

[0066] Next, the worker can use the U-shaped handle 5 to move the steel bars in the steel bar loading carrier 1 to the required location. After arriving at the destination, turn on the motor 403-1A to move the limit shaft 403-2A1 downward to just below the loading and unloading auxiliary component 402, drag one end of the steel bar, and with the assistance of the loading and unloading auxiliary component 402, unload the steel bar from the steel bar loading carrier 1 to complete the steel bar transportation work.
