[0001] This utility model relates to the field of enamel tube manufacturing technology, and in particular to an enamel tube transfer vehicle. Background Technology

[0002] Enameled pipe is a type of pipe with a steel base and a glazed surface formed by enameling. It possesses properties such as high temperature resistance, corrosion resistance, and wear resistance. During the production process, transfer vehicles are used to move the enamel pipes between various workstations.

[0003] Chinese utility model patent CN219056265U discloses a stackable enamel pipe transport vehicle, which includes: a frame with multiple casters rotatably connected to the bottom; stop blocks fixed around the top of the frame to restrict the rolling of the enamel pipes; and multiple sets of support components that can be stacked vertically. Each set of support components includes a horizontal support portion, a side stop portion, and a limiting portion. The horizontal support portion supports the enamel pipes, with the horizontal support portion on the bottom support component contacting the stop block. The side stop portions are fixed at both ends of the top of the horizontal support portion, and the limiting portions are fixed at both ends of the bottom of the horizontal support portion, located outside the side stop portions of the adjacent lower support component. This stackable enamel pipe transport vehicle increases the number of enamel pipes that can be placed by stacking more support components, thus increasing the efficiency of a single transport. The support components are easy to assemble and disassemble, and multiple layers can be flexibly assembled according to transport needs.

[0004] When using the stackable enamel tube transfer cart disclosed in the aforementioned utility model patent, if the number of enamel tubes is insufficient to fill the support, the enamel tubes will roll on the support during the movement of the transfer cart, causing the enamel tubes to collide with each other or with the support, resulting in damage to the surface of the enamel tubes and affecting product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a enamel tube transfer vehicle, which solves the problem that the surface of the enamel tube is damaged due to collision when it rolls during movement.

[0006] According to an embodiment of this utility model, an enamel tube transfer vehicle includes a frame with wheels on it and a load-bearing assembly. The load-bearing assembly includes a support frame with an opening at one end. A movable sliding rod is provided on one side of the support frame. A rotatable stop bar is provided on the sliding rod, and a limiting block is fitted on the stop bar. When the stop bar rotates, it passes through the opening and enters or exits the support frame. After the stop bar enters the support frame, moving the sliding rod can cause the limiting block to move closer to or away from the opening. A locking plate is provided at the end of the stop bar away from the sliding rod. The locking plate can move along the axial direction of the stop bar. After the stop bar enters the support frame, the locking plate is located on the side of the support frame away from the sliding rod. The locking plate has a threaded hole and a locking screw that mates with the threaded hole. The locking screw abuts against the support frame.

[0007] Furthermore, the supporting frame is provided with two guide grooves spaced apart in the vertical direction. The length direction of the guide groove is consistent with the moving direction of the sliding rod. The two ends of the sliding rod are respectively provided with guide rods, and the guide rods and guide grooves are matched one-to-one.

[0008] Furthermore, one of the guide rods is provided with a threaded portion and a locking nut that mates with the threaded portion, the locking nut abutting against the support frame.

[0009] Furthermore, one end of the stop rod is provided with a connecting sleeve, which is sleeved on the sliding rod. Two limiting cylinders are provided on the sliding rod at intervals, and the two limiting cylinders abut against the opposite sides of the connecting sleeve respectively.

[0010] Furthermore, the end of the stop bar away from the sliding bar is provided with a limiting rod and the cross-section of the limiting rod is polygonal, and the locking plate is provided with a limiting hole that cooperates with the limiting rod.

[0011] Furthermore, the stop bar is provided with a plurality of limiting blocks spaced apart along the axial direction of the stop bar, and each limiting block is provided with a limiting groove. After the stop bar enters the bearing frame, the limiting groove is located on the side of the limiting block away from the opening.

[0012] Furthermore, the frame is provided with at least two of the load-bearing components, and the load-bearing components are stacked on the frame.

[0013] Furthermore, the upper surface of the support frame is provided with a plug-in seat and the lower surface of the support frame is provided with a positioning seat. The positioning seat is provided with a positioning hole and the plug-in seat is provided with a positioning post that cooperates with the positioning hole.

[0014] Furthermore, the frame is provided with a connector, the lower surface of the support frame is provided with a positioning seat, the positioning seat is provided with a positioning hole, and the connector is provided with a positioning post that mates with the positioning hole.

[0015] Furthermore, the frame is also provided with a push-pull rod, which is located at the end of the load-bearing frame away from the opening.

[0016] Compared to existing technologies, this utility model has the following advantages: By employing a load-bearing assembly mounted on the frame to place the enamel tubes, the enamel tubes are sequentially inserted into the load-bearing frame from the opening, arranging them in a row within the frame. Then, the stop lever is rotated to allow it to enter the load-bearing frame from the opening, and the sliding rod is moved until the limiting block abuts against the enamel tube closest to the opening. This restricts the position of the enamel tubes on the load-bearing frame through the limiting block and the stop lever, preventing the enamel tubes from rolling within the frame. After the limiting block is in place, the locking plate is moved to bring the locking screw closer to the load-bearing frame, and then the locking screw is rotated to... The locking screw engages with the load-bearing frame to lock the position of the stop bar, ensuring the stability of the enamel tube within the load-bearing frame during frame movement. After the enamel tube is moved to the predetermined position, first rotate the locking screw to move it away from the load-bearing frame, then rotate the stop bar to remove it from the load-bearing frame, allowing the enamel tubes to be removed one by one. This solves the technical problem of enamel tubes rolling during movement and causing surface damage due to collisions. It achieves the technical effect of ensuring the enamel tube remains stable during transport and avoiding damage caused by collisions. Furthermore, it is simple to operate and convenient to use.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a transfer vehicle for enamel tube 100, which is used to carry enamel tube 100 during the transfer process, so as to facilitate the transportation of enamel tube 100 between various workstations.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3The enamel tube 100 transfer vehicle includes a frame 1 with wheels 11 for movement on the ground. The frame 1 also has a support assembly 2 for placing the enamel tube 100. The support assembly 2 includes a support frame 21 with an opening 22 at one end, through which the enamel tube 100 can be placed or removed. A movable sliding rod 3 is provided on one side of the support frame 21, with a rotatable stop 4 and a limiting block 5 fitted onto the stop 4. When the stop 4 rotates, it passes through the opening 22 into or out of the support frame 21. After the stop 4 enters the support frame 21, moving the sliding rod 3 allows the limiting block 5 to move closer to or away from the opening 22. After the enamel tube 100 is placed in the support frame 21, rotating the stop 4 and moving the sliding rod 3 allows the limiting block 5 to move closer to or away from the opening 22. Position block 5 abuts against the enamel tube 100 closest to the opening 22, thereby limiting the enamel tube 100 and preventing it from rolling on the support frame 21; the end of the stop rod 4 away from the sliding rod 3 is provided with a locking plate 6, which can move along the axial direction of the stop rod 4. After the stop rod 4 enters the support frame 21, the locking plate 6 is located on the side of the support frame 21 away from the sliding rod 3. The locking plate 6 is provided with a threaded hole and a locking screw 61 that cooperates with the threaded hole. By sliding the locking plate 6 on the stop rod 4, the locking plate 6 can be brought closer to the support frame 21 and the locking screw 61 can be moved above the support frame 21. By rotating the locking screw 61 to abut against the support frame 21, the position of the stop rod 4 on the support frame 21 can be locked.

[0026] Specifically, the operation steps for transporting enamel tubes 100 using the enamel tube 100 transfer cart provided in this embodiment are as follows: When placing the enamel tubes 100 onto the enamel tube 100 transfer cart, the enamel tubes 100 are sequentially inserted into the support frame 21 from the opening 22 so that the enamel tubes 100 are arranged in a row in the support frame 21. Then, the stop bar 4 is rotated so that the stop bar 4 enters the support frame 21 from the opening 22, and the sliding rod 3 is moved until the limiting block 5 abuts against the enamel tube 100 closest to the opening 22. Thus, the position of the enamel tube 100 on the support frame 21 is restricted by the limiting block 5 and the stop bar 4, preventing the enamel tube 100 from rolling in the support frame 21. After the movement is completed, the moving locking plate 6 brings the locking screw 61 close to the support frame 21. Then, the locking screw 61 is rotated to abut against the support frame 21, thus locking the position of the stop bar 4 and ensuring that the position of the enamel tube 100 within the support frame 21 remains stable during the movement of the frame 1. When unloading the enamel tube 100 from the enamel tube 100 transfer vehicle after it has been moved to the predetermined position, the locking screw 61 is first rotated to move it away from the support frame 21. Then, the stop bar 4 is rotated to remove it from the support frame 21 and move the limiting block 5 away from the enamel tube 100. At this time, the enamel tube 100 is removed from the support frame 21 in sequence. The enamel tube 100 transfer vehicle provided in this embodiment can ensure that the enamel tube 100 remains stable during the transfer process, effectively avoiding damage caused by the enamel tube 100 colliding with each other or with the bearing component 2 during transportation. Furthermore, the operation of picking up and putting down the enamel tube 100 is simple and convenient.

[0027] like Figure 2 and Figure 3 As shown, the supporting frame 21 has two guide grooves 23 spaced apart vertically. The length direction of the guide grooves 23 is consistent with the moving direction of the sliding rod 3. Guide rods 31 are respectively provided at both ends of the sliding rod 3, and the guide rods 31 correspond one-to-one with the guide grooves 23. The guide grooves 23 are used to limit the moving direction of the sliding rod 3 on the supporting frame 21, preventing the sliding rod 3 from deviating from the preset direction during movement. Furthermore, the two guide rods 31 at both ends of the sliding rod 3 correspond one-to-one with the two spaced guide grooves 23 on the supporting frame 21, which helps to improve the stability of the cooperation between the sliding rod 3 and the supporting frame 21.

[0028] In detail, one of the guide rods 31 is provided with a threaded portion 32 and a locking nut 33 that mates with the threaded portion 32. The locking nut 33 abuts against the support frame 21. By providing the threaded portion 32 on one of the guide rods 31 and the locking nut 33 that mates with the threaded portion 32, the position of the sliding rod 3 on the support frame 21 is locked. After the sliding rod 3 moves to a position where the limiting block 5 contacts the enamel tube 100, the locking nut 33 is rotated to abut against the support frame 21, thus fixing the position of the sliding rod 3. This prevents the enamel tube 100 from rolling within the support frame 21 due to unexpected movement of the sliding rod 3 during operation of the locking screw 61 and during transportation. When it is necessary to adjust the position of the sliding rod 3 again, the locking nut 33 is rotated to move away from the support frame 21. The operation is simple.

[0029] Please combine Figure 2 , Figure 4 and Figure 5 One end of the stop rod 4 is provided with a connecting sleeve 41, which is sleeved on the sliding rod 3. Two limiting sleeves 34 are spaced apart on the sliding rod 3, and the two limiting sleeves 34 respectively abut against the opposite sides of the connecting sleeve 41. The connecting sleeve 41 at the end of the stop rod 4 is used to connect the sliding rod 3, so that the stop rod 4 can rotate smoothly relative to the sliding rod 3. The two limiting sleeves 34 spaced apart on the sliding rod 3 clamp the connecting sleeve 41 in the middle, so that the position of the stop rod 4 on the bearing frame 21 remains stable and prevents the stop rod 4 from moving in the vertical direction, which would cause the limiting block 5 to detach from the enamel tube 100.

[0030] In this embodiment, a limiting rod 42 is provided at the end of the stop rod 4 away from the sliding rod 3, and the cross-section of the limiting rod 42 is polygonal. The locking plate 6 is provided with a limiting hole that cooperates with the limiting rod 42. The limiting rod 42 cooperates with the limiting hole on the locking plate 6 to allow the locking plate 6 to slide on the stop rod 4, thereby adjusting the position of the locking plate 6 and moving the locking screw 61 closer to or away from the bearing frame 21. The cross-section of the limiting rod 42 is set to be polygonal to prevent the locking plate 6 from rotating relative to the stop rod 4, ensuring that the position of the locking plate 6 remains stable during the rotation of the locking screw 61.

[0031] like Figure 3 and Figure 5As shown, the stop bar 4 is provided with a plurality of limiting blocks 5 spaced apart along its axial direction, and each limiting block 5 is provided with a limiting groove 51. After the stop bar 4 enters the bearing frame 21, the limiting groove 51 is located on the side of the limiting block 5 away from the opening 22. By providing the limiting groove 51 on the limiting block 5 that fits against the surface of the enamel tube 100, the stability of the cooperation between the limiting block 5 and the enamel tube 100 is improved, ensuring that the enamel tube 100 will not roll or rotate within the bearing frame 21 during the movement of the enamel tube 100 transfer vehicle, thereby avoiding damage to the surface of the enamel tube 100.

[0032] Please refer to Figure 1 and Figure 3 The frame 1 is provided with at least two of the aforementioned load-bearing components 2, and the load-bearing components 2 are stacked on the frame 1. Multiple load-bearing components 2 are provided on the frame 1, and each load-bearing component 2 can hold several enamel tubes 100, thereby increasing the capacity of the enamel tube 100 transport vehicle and facilitating the one-time transport of a large number of enamel tubes 100. Stacking multiple load-bearing components 2 on the frame 1 improves the overall stability of the enamel tube 100 transport vehicle while also facilitating the loading and unloading of the enamel tubes 100.

[0033] Specifically, the upper surface of the support frame 21 is provided with a plug-in seat 24, and the lower surface of the support frame 21 is provided with a positioning seat 25. The positioning seat 25 is provided with a positioning hole, and the plug-in seat 24 is provided with a positioning post 26 that mates with the positioning hole. The stacked support frames 21 are positioned by the cooperation of the positioning seat 25 and the plug-in seat 24. After the support frames 21 are stacked, the positioning post 26 is inserted into the corresponding positioning hole, so that the connection between the multiple support components 2 is reliable and some of the support components 2 are prevented from falling off the frame 1 when the enamel tube 100 transfer vehicle moves.

[0034] like Figure 1 As shown, the frame 1 is provided with a connector 24, and the lower surface of the support frame 21 is provided with a positioning seat 25. The positioning seat 25 is provided with a positioning hole, and the connector 24 is provided with a positioning post 26 that mates with the positioning hole. The connector 24 on the frame 1 mates with the positioning seat 25 on the lower surface of the support frame 21 to facilitate positioning of the support assembly 2 when it is placed on the frame 1. The positioning post 26, in conjunction with the positioning hole, prevents the support assembly 2 from moving on the frame 1, thereby improving the stability of the support assembly 2 on the frame 1.

[0035] In detail, side baffles 27 are respectively provided at opposite ends of the support frame 21, and the side baffles 27 are in contact with the two ends of the frame 1 or the two ends of another support frame 21. When the support assembly 2 is placed on the frame 1 or multiple support assemblies 2 are stacked, the side baffles 27 located at both ends of the support frame 21 are in contact with the two ends of the frame 1 or the two ends of another support frame 21 located below, further improving the reliability of the cooperation between the support frame 21 and the frame 1 and the reliability of the cooperation between the support assemblies 2.

[0036] like Figure 1 As shown, in this embodiment, the frame 1 is also provided with a push-pull rod 12, which is located at the end of the supporting frame 21 away from the opening 22. By operating the push-pull rod 12, the frame 1 can be moved on the ground to facilitate the movement of the enamel tube 100 transfer cart to a predetermined position for loading and unloading the enamel tube 100, thus facilitating the use of the enamel tube 100 transfer cart.
