Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation equipment, in particular to a transportation device for splicing steel pipes. Background Art

[0002] China is currently in the peak period of pumped storage power station construction. As a promising energy storage facility, pumped storage power stations have a large head difference between upstream and downstream and a long water diversion system. Each pumped storage power station has a large number of large-diameter pressure steel pipes that need to be produced. Due to the high head, the steel pipes are generally spliced in sections of 3 meters, and adjacent sections of steel pipes are connected by 4 to 5 circles of stiffening rings.

[0003] Steel pipe butt jointing is typically performed using a seam welding trolley, which transports the steel pipe along a track to the previous section. The welder then uses the rolling motion of the pipe to weld a stiffening ring between the two pipes. Existing seam welding trolleys typically transport the pipe axially to facilitate butt jointing. To facilitate loading, the pipes are placed on the trolley with both ends open. This can easily cause the pipe to tilt and slip from one end of the trolley during transportation and welding, potentially leading to misalignment of the front and rear pipes and unstable welding. In more serious cases, this can create significant safety hazards. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a steel pipe splicing transportation device with a simple structure, which avoids inaccurate alignment of front and rear steel pipes and welding instability and can promptly alarm to prevent major safety hazards.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A transport device for splicing steel pipes comprises a transport base, the transport base being provided with a rolling pipe-bearing assembly for supporting the steel pipes, the front and rear ends of the transport base being respectively provided with blocking mechanisms that can swing back and forth or move back and forth, the transport base being provided with a collision alarm mechanism on the outside of each blocking mechanism, the blocking mechanism being used to form a blockage at the end of the steel pipe and to swing or move to touch the collision alarm mechanism after being subjected to an upper limit thrust, thereby causing the collision alarm mechanism to alarm.

[0007] As a further improvement of the above technical solution:

[0008] The collision alarm mechanism includes a mounting frame, a travel switch and an alarm. The mounting frame is fixed on the transport base, the alarm is arranged on the mounting frame, and the travel switch is arranged on the side of the mounting frame facing the blocking mechanism and is electrically connected to the alarm.

[0009] The blocking mechanism includes a blocking plate and a blocking wheel. The blocking plate can swing back and forth or move back and forth on the transport base. The blocking wheel is arranged on the inner side of the blocking plate. A touch portion is provided on the outer side of the blocking plate. The touch portion is arranged corresponding to the travel switch.

[0011] The outer side of the bottom end of the blocking plate is rotatably connected to the transport base through a pin shaft, and the inner side is connected to the transport base through a bolt.

[0013] The mounting frame is provided with a mounting sleeve, the outer end of the mounting sleeve is provided with a plug, and the elastic component is sleeved in the mounting sleeve and located between the blocking plate and the plug.

[0014] The plug is threadedly connected to the mounting sleeve, and one end of the plug extending out of the mounting sleeve is provided with a screwing portion.

[0030] Example 1:

[0031] Figures 1 to 3 An embodiment of the utility model of the transport device for steel pipe splicing is shown. The transport device for steel pipe splicing of this embodiment includes a transport base 1. The transport base 1 is provided with a rolling pipe supporting assembly 2 for supporting the steel pipe 3. The front and rear ends of the transport base 1 are respectively provided with blocking mechanisms 4 that can swing back and forth or move back and forth. The transport base 1 is provided with a collision alarm mechanism 5 on the outside of each blocking mechanism 4. The blocking mechanism 4 is used to form a blockage at the end of the steel pipe 3, and swing or move to touch the collision alarm mechanism 5 after being subjected to the upper limit thrust, so that the collision alarm mechanism 5 alarms.

[0032] In use: The steel pipe 3 is placed on the rolling pipe support assembly 2 and arranged along the forward and backward movement direction of the transport base 1, so that the blocking mechanisms 4 at the front and rear ends of the transport base 1 respectively block the front and rear ends of the steel pipe 3, preventing the steel pipe 3 from sliding forward and backward during transportation and welding, avoiding misalignment of the front and rear steel pipes and unstable welding. In addition, when the steel pipe 3 tilts and slides forward and backward, if the tilt angle is large, the blocking mechanism 4 will swing under the upper limit thrust or move to contact the collision alarm mechanism 5, causing the collision alarm mechanism 5 to alarm, and the transportation and welding operations will be stopped in time to prevent major safety hazards.

[0033] Furthermore, in this embodiment, the collision alarm mechanism 5 includes a mounting bracket 51, a limit switch 52, and an alarm 53. The mounting bracket 51 is fixed to the transport base 1, and the alarm 53 is mounted on the mounting bracket 51. The limit switch 52 is located on the side of the mounting bracket 51 facing the blocking mechanism 4 and is electrically connected to the alarm 53. When the blocking mechanism 4 is subjected to the upper limit thrust, it swings or moves until it contacts the limit switch 52, causing the alarm 53 to sound. The alarm 53 sounds when the limit switch 52 is hit, resulting in a simple structure and low manufacturing cost.

[0034] Furthermore, if Figure 2As shown, in this embodiment, the blocking mechanism 4 includes a blocking plate 41 and a blocking wheel 42. The blocking plate 41 is mounted on the transport base 1 so as to be capable of swinging back and forth or moving back and forth. The blocking wheel 42 is disposed on the inner side of the blocking plate 41. The outer side of the blocking plate 41 is provided with a contact portion 411, which is arranged corresponding to the travel switch 52. The inner side of the blocking plate 41 faces the rolling bearing assembly 2. The blocking wheel 42 blocks the end of the steel pipe 3, providing a certain forward and backward blocking force on the steel pipe 3 without restricting its rotation. Preferably, the axial direction of the blocking wheel 42 is perpendicular to the forward and backward movement direction of the transport base 1.

[0035] Furthermore, in this embodiment, the bottom end of the blocking plate 41 is detachably connected to the transport base 1. Before placing the steel pipe 3, the blocking mechanism 4 can be removed and then installed after the steel pipe 3 is placed, thereby facilitating the placement of the steel pipe 3 on the rolling support assembly 2.

[0036] Furthermore, in this embodiment, the outer side of the bottom end of the blocking plate 41 is rotatably connected to the transport base 1 via a pin 43, and the inner side is connected to the transport base 1 via a bolt 44. The blocking plate 41 can be assembled and disassembled by simply disassembling the pin 43 and bolt 44, resulting in a simple structure and convenient assembly and disassembly. The blocking plate 41 is made of a material that allows it to swing when the upper portion is subjected to an upper limit thrust, such as a steel plate, or other metal plate with one end fixed and the other end capable of swinging when subjected to a force.

[0037] Furthermore, in this embodiment, the rolling pipe support assembly 2 includes two rows of support wheels 21, one on each side of the transport base 1. The bottom of the transport base 1 is provided with movable wheels 8, with the axial direction of the support wheels 21 perpendicular to the movable wheels 8. A row of support wheels 21 is provided on each side of the transport base 1, with the support wheels 21 in each row spaced apart along the forward and backward movement direction of the transport base 1. The two rows of support wheels 21 are used to jointly support the steel pipe 3, enabling both rotation of the steel pipe 3 and limiting the left and right position of the steel pipe 3.

[0038] Example 2:

[0039] Figure 4 and Figure 5 Another embodiment of the transportation device for steel pipe splicing of the present invention is shown. The structure of this embodiment is basically the same as that of the first embodiment, and the only difference is that the blocking plate 41 is in sliding cooperation with the transportation base 1, and an elastic component 6 is provided between the blocking plate 41 and the corresponding mounting bracket 51. The blocking plate 41 relies on the elastic force of the elastic component 6 to block the end of the steel pipe 3. After receiving the upper limit thrust, the blocking plate 41 moves toward the mounting bracket 51 to touch the travel switch 52, so that the alarm 53 sounds an alarm. Compared with swinging to touch the travel switch 52, it is easier to select materials for the blocking plate 41 that can meet the requirements of moving to touch the travel switch 52, and the blocking plate 41 can be a rigid plate. Preferably, as Figure 5As shown, a slide groove is provided on the transport base 1, and the bottom end of the blocking plate 41 is slidably arranged in the slide groove.

[0040] Furthermore, in this embodiment, a mounting sleeve 7 is provided on the mounting frame 51. A plug 71 is provided at the outer end of the mounting sleeve 7. The elastic member 6 is sleeved within the mounting sleeve 7 and positioned between the blocking plate 41 and the plug 71. The mounting sleeve 7 is fixedly connected to the mounting frame 51, such as by welding. The axial direction of the mounting sleeve 7 is aligned with the forward and backward movement direction of the transport base 1.

[0041] Furthermore, in this embodiment, the plug 71 is threadedly connected to the mounting sleeve 7, and a screwing portion 72 is provided at one end of the plug 71 extending from the mounting sleeve 7. Loosening the plug 71 allows the spacing between the two blocking mechanisms 4 to be expanded, facilitating placement of the steel pipe 3. Furthermore, tightening the plug 71 allows the blocking force of the blocking mechanism 4 on the steel pipe 3 to be adjusted, providing good adjustability.

[0042] Furthermore, in this embodiment, the elastic component 6 is a spring.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations.
