Description

Technical Field

[0001] The present invention relates to the technical field of longitudinal beam transfer, and particularly relates to a longitudinal beam transfer trolley. Background Art

[0002] After the longitudinal beam is roll-formed, it needs to be transferred and transported to the next working station. Since the transfer trolley has the characteristics of stable structure, flexible movement, convenient operation, large load capacity, etc., the transfer trolley is widely used when the longitudinal beam needs to be transferred and transported.

[0003] Currently, the transfer trolleys used in the production workshop simply use the roof plane as the bearing surface. After the formed longitudinal beam is magnetically adsorbed by the manipulator, it is transferred and placed on the bearing surface. Since the longitudinal beam has a C-shaped structure, it is placed in an up-and-down corresponding manner. However, after placing multiple layers, the upper longitudinal beam is prone to displacement and has poor stability. During the transfer, personnel need to follow around the transfer trolley. When displacement occurs, the transfer trolley can be stopped in time to adjust the longitudinal beam. This results in low work efficiency, high labor intensity of personnel, time-consuming and laborious, and has a certain degree of danger.

[0004] Therefore, there is an urgent need for a transfer trolley that can conveniently and safely transfer the longitudinal beam, can stably fix the longitudinal beam to prevent displacement, reduce the need for personnel to follow, improve stability. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide a longitudinal beam transfer trolley that can conveniently and safely transfer the roll-formed longitudinal beam, stably fix the longitudinal beam during the transfer process to prevent the longitudinal beam from displacing, improve stability; at the same time, reduce the situation of personnel following, save time and effort, improve work efficiency, and reduce labor costs.

[0006] To solve the above technical problem, the technical solution of the present invention is:

[0007] A longitudinal beam transfer trolley includes a trolley body. The trolley body includes a placement surface, and a plurality of connection holes are opened on the placement surface;

[0008] A limiting device is fixedly connected in the connection hole, and two relatively arranged limiting devices limit the same longitudinal beam.

[0009] Preferably, the limiting device includes a limiting body. A cavity is opened downward at the center of the top of the limiting body, and the size and shape of the cavity correspond to those of the connection hole one by one;

[0010] A limit plate is rotatably mounted on the outer wall of one side of the limit body through a rotating shaft, a torsion spring is arranged between the limit plate and the outer wall, the torsion spring is coaxially arranged with the rotating shaft, and two torsion output ends of the torsion spring are respectively in contact with the outer wall and the limit plate;

[0011] A connecting block is arranged at the bottom of the limiting body, and the connecting block is used in conjunction with the connecting hole. An auxiliary bearing device is arranged between the connecting block and the limiting body.

[0012] Preferably, the auxiliary bearing device is an inverted trapezoidal structure, and the auxiliary bearing device comprises a bearing surface and a stress surface;

[0013] The bearing surface is used to bear the longitudinal beams to be transported;

[0014] The stress surface is fixedly connected to the connection block by welding.

[0015] Preferably, an anti-slip layer is bonded to the bearing surface.

[0016] Preferably, the connection hole and the connection block are threadedly connected.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are:

[0018] In the present invention, a connecting hole is opened on the placement surface, and a limiting device is fixedly connected in the connecting hole. After the limiting devices are relatively arranged, the longitudinal beam can be limited to prevent shaking during transportation and improve stability. At the same time, the limiting device includes a limiting plate, and a torsion spring is arranged between the limiting plate and the outer wall. Under the action of the torsion spring, the top end of the limiting plate abuts against the outer wall, and the bottom end extends to the side away from the outer wall. When the manipulator electromagnetically absorbs the longitudinal beam and places it between the two limiting devices, the limiting plate no longer abuts against the outer wall under the action of the longitudinal beam, thereby allowing the longitudinal beam to pass. An auxiliary bearing device is arranged between the limiting body and the connecting block, and the auxiliary bearing device carries the longitudinal beam. The two longitudinal beams are relatively placed and placed in the area formed by the two relatively arranged limiting devices. After the placement is completed, the bottom end of the limiting plate abuts against the top surface of the upper longitudinal beam, thereby limiting the two longitudinal beams and preventing displacement.

[0019] In the present invention, the auxiliary bearing device is an inverted trapezoidal structure, and the auxiliary bearing device includes a bearing surface and a stress surface. The bearing surface can bear the longitudinal beam to achieve the longitudinal beam placement requirements, and the stress surface can guide the weight of the longitudinal beam and concentrate it on the placement surface to prevent the bearing surface from deformation. At the same time, while reducing the material consumption, the requirements of the bearing surface for bearing the longitudinal beam are met to the greatest extent.

[0020] In the present invention, the anti-skid layer is bonded to the bearing surface, and the anti-skid layer can increase the friction between the longitudinal beam and the longitudinal beam, thereby preventing the longitudinal beam from being displaced along the moving direction, and further improving the stability of the longitudinal beam.

[0021] To sum up, the longitudinal beam transfer trolley provided by the present invention can conveniently and safely transfer the longitudinal beam after roller forming. During the transportation process, the longitudinal beam can be stably fixed to prevent the longitudinal beam from displacement and improve stability. At the same time, the situation of personnel following can be reduced, which saves time and effort, improves work efficiency and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] like Figures 1 to 4 As shown, the present invention comprises a trolley body 1 , the trolley body 1 comprises a placement surface 11 , and a plurality of connection holes 12 are formed on the placement surface 11 .

[0033] A limiting device 2 is fixedly connected in the connection hole 12 , and two limiting devices 2 arranged opposite to each other limit the same longitudinal beam 3 .

[0034] like Figure 5 and Figure 6 As shown, the limiting device 2 includes a limiting body 21 , and a cavity 22 is downwardly opened at the top center of the limiting body 21 , and the cavity 22 corresponds to the size and shape of the connecting hole 12 one by one.

[0035] A limit plate 24 is rotatably mounted on the outer wall of one side of the limit body 21 through a rotating shaft 23. A torsion spring 25 is arranged between the limit plate 24 and the outer wall. The torsion spring 25 is coaxially arranged with the rotating shaft 23. Two torsion output ends 251 of the torsion spring 25 are respectively in contact with the outer wall and the limit plate 24.

[0036] A connecting block 26 is disposed at the bottom of the limiting body 21 . The connecting block 26 is used in conjunction with the connecting hole 12 . An auxiliary bearing device 27 is disposed between the connecting block 26 and the limiting body 21 .

[0037] When actually carrying out the longitudinal beam transfer limiting, the limiting device 2 located on the first layer has its connection block 26 fixedly connected to the inside of the connection hole 12, while the limiting device 2 located on the second layer has its connection block 26 fixedly connected to the cavity 22, and they are fixedly connected upward in sequence to realize the installation of the limiting devices 2 on the third layer, the fourth layer and above, thereby meeting the technical requirements of the multi-layer transfer limiting longitudinal beam 3 and improving the transfer efficiency.

[0038] The connection hole 12 and the connection block 26 are threadedly connected.

[0039] The limiting device 2 can limit the longitudinal beam 3 to prevent shaking during transportation and improve stability.

[0040] like Figure 5 As shown, the auxiliary bearing device 27 is an inverted trapezoidal structure, and the auxiliary bearing device 27 includes a bearing surface 271 and a stress surface 272 .

[0041] The bearing surface 271 is used to bear the longitudinal beam 3 to be transported, and an anti-skid layer 28 is bonded to the bearing surface 271, and the stress surface 272 is fixedly connected to the connection block 26 by welding. The bearing surface 271 can bear the longitudinal beam 3 to meet the longitudinal beam placement requirements, while the stress surface 272 can guide the weight of the longitudinal beam 3 and conduct it to the placement surface 11 to prevent the bearing surface 271 from deforming. At the same time, the bearing surface 271 can meet the requirements of bearing the longitudinal beam 3 to the greatest extent while reducing the material consumption; the bearing surface 271 is bonded with an anti-skid layer 28, which can be made of rubber material, and the anti-skid layer 28 can increase the friction between the longitudinal beam 3 and prevent the longitudinal beam 3 from being displaced along the movement direction, further improving the stability of the longitudinal beam 3.

[0042] When the present invention is in use, the trolley body 1 is moved to the vicinity of the longitudinal beam 3 to be placed, and the staff connects the limiting device 2 to the inside of the connecting hole 12 through the connecting block 26, and the two are arranged opposite to each other. According to actual needs, the connecting hole 12 is connected to the connecting block through the thread, which can be a full thread connection or a partial thread connection. After the installation of the first layer of limiting devices 2 is completed, the longitudinal beam 3 after roll forming is electromagnetically sucked by the robot and placed in the placement area formed by the two limiting devices 2. During the placement process, the limiting plate 24 is under the action of the longitudinal beam 3. The top of the longitudinal beam 3 is no longer in contact with the outer wall, and the longitudinal beam 3 is opened to allow the longitudinal beam 3 to pass. An auxiliary bearing device 27 is provided between the limiting body 21 and the connecting block 26. The auxiliary bearing device 27 carries the longitudinal beam 3, completes the placement of one longitudinal beam 3, and then places the second longitudinal beam 3. The second longitudinal beam 3 is placed in the opposite direction to the previous longitudinal beam 3, and the two are arranged relative to each other to form a mouth-shaped structure. After the second longitudinal beam 3 is placed, it is defined as the upper longitudinal beam. After the placement is completed, the bottom end of the limiting plate 24 abuts against the top surface of the upper longitudinal beam to limit the two longitudinal beams and prevent displacement. After the first layer of longitudinal beams 3 are placed, the staff threadedly connects the second layer of limiting device 2 to the cavity 22 of the first layer of limiting device 2 through the connecting block 26, and installs the second layer of limiting device 2. After the installation is completed, the longitudinal beam 3 is placed by the manipulator, and so on, to complete the placement requirements of multiple layers of longitudinal beams 3. After all the placement is completed, the trolley body 1 transports the longitudinal beam 3 to complete a transportation operation. After being transported to the designated location, the staff will rotate the uppermost limiting device 2 in the opposite direction, so that the limiting plate 24 on the adjacent limiting device 2 faces the forward direction of the present invention, or is opposite to the forward direction of the present invention, and releases the state in which the bottom end of the limiting plate 24 abuts against the top surface of the longitudinal beam, thereby achieving the purpose of taking out the longitudinal beam from above the adjacent limiting device 2 for unloading.

[0043] To sum up, the longitudinal beam transfer trolley provided by the present invention can conveniently and safely transfer the longitudinal beam after roller forming. During the transportation process, the longitudinal beam can be stably fixed to prevent the longitudinal beam from displacement and improve stability. At the same time, the situation of personnel following can be reduced, which saves time and effort, improves work efficiency and reduces labor costs.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
