Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe transfer, specifically to a steel pipe transfer device. Background Technology

[0002] Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers, but they are also an economical steel material. Using steel pipes to manufacture building structural frames, columns, and mechanical supports can reduce weight, save 20-40% of metal, and enable factory-based mechanized construction. Using steel pipes to construct highway bridges not only saves steel and simplifies construction, but also significantly reduces the area requiring protective coatings, saving investment and maintenance costs. Therefore, steel pipes are widely used in various fields.

[0003] Large factories typically have specialized automated transfer devices or large overhead cranes to transport steel pipes. However, construction sites generally do not have automated transfer devices or large overhead cranes. The most common economical and simple steel pipe transfer device on the market consists of a handle, an extension arm, a connecting frame fixedly connected to the extension arm, a pair of support wheels mounted on both ends of the connecting frame, and a semi-circular bracket that can rotate freely on the connecting frame.

[0004] The aforementioned transfer device is not only simple in structure and low in cost, but also easy to carry, so it is widely used on construction sites. When using it, you only need to tilt the semi-ring bracket and move one end of the semi-ring bracket to the gap under the steel pipe to lift the end of the steel pipe upward and let it fall into the semi-ring bracket. It is simple and convenient to use. However, when there is no gap between the steel pipe and the ground, another person is needed to assist in first lifting the end of the steel pipe upward, then moving one end of the semi-ring bracket to the bottom of the steel pipe to lift the steel pipe, and then another person moves to the other end of the steel pipe to use the transfer device to lift both ends of the steel pipe. One person needs to move between the two ends of the steel pipe, which will affect the handling efficiency. Therefore, it is necessary to design a steel pipe transfer device. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem in the prior art that when there is no gap between the steel pipe and the ground, another auxiliary is needed to lift the end of the steel pipe.

[0006] To achieve the above objectives, this utility model provides a steel pipe transfer device, comprising: a connecting frame with support wheels at both ends; a support shaft perpendicular to the connecting frame in length direction and mounted in the middle of the connecting frame via a first bearing; a semi-ring bracket fixedly connected in the middle to the top of the support shaft; a semi-ring auxiliary frame connected to one end of the semi-ring bracket via a rotating shaft parallel to the axis of the semi-ring bracket; an extension arm fixedly connected to the connecting frame; a handle mounted on the end of the extension arm away from the connecting frame; and a control unit for driving the semi-ring auxiliary frame to rotate closer to the semi-ring bracket. The control unit includes a pull handle slidably mounted on the end of the extension arm away from the connecting frame.

[0007] Preferably, the rotating shaft is rotatably connected to the end of the semi-ring bracket and fixedly connected to the end of the semi-ring auxiliary frame. The control unit further includes a transmission disc slidably sleeved on the support shaft, a transmission mechanism mounted on the transmission disc and connected to the rotating shaft, at least one sliding arm parallel to the support shaft and sliding through the connecting frame along its own length direction, a transmission component fixedly connected to one end of the sliding arm and having a U-shaped cross-section slidably sleeved on the edge of the transmission disc, a first guide mounted on the side of the connecting frame away from the semi-ring bracket, a connector fixedly connected to the end of the sliding arm away from the transmission component, and a pull rope with one end fixedly connected to the connector and the other end sliding through the first guide and connected to the handle.

[0008] Preferably, the transmission mechanism includes a gear fixedly sleeved on a rotating shaft along the same axis, a turntable mounted on the outer wall of a semi-ring bracket via a connecting shaft parallel to the rotating shaft, an inclined first connecting arm with one end hinged to the turntable via a first hinge shaft parallel to the connecting shaft and away from the gear, and a second connecting arm with both ends hinged to the middle of the first connecting arm and the transmission disc via second hinge shafts respectively.

[0009] The turntable has a meshing part on its side wall that meshes with the gear. The end of the first connecting arm away from the turntable is inclined towards the transmission disk, and the end of the second connecting arm away from the transmission disk is inclined away from the support shaft.

[0010] The upper surface of the first connecting arm away from the turntable end is provided with a first strip-shaped through groove of the same length direction for the support shaft to pass through. The side wall of the first connecting arm away from the turntable end is provided with a second strip-shaped through groove of the same length direction and communicating with the first strip-shaped through groove. A first guide bolt passing through the second strip-shaped through groove is fixedly connected to the support shaft.

[0011] Preferably, the end of the extension arm away from the connecting frame is provided with a third strip-shaped through groove in the same length direction, and a second guide bolt that slides through the third strip-shaped through groove is fixedly connected to the handle.

[0012] Preferably, the extension arm is equipped with at least one second guide through which the pull rope slides.

[0013] Preferably, a pair of mounting seats are fixedly connected to the outer wall of the semi-ring bracket, and the two ends of the connecting shaft are respectively mounted on the pair of mounting seats. The turntable is mounted on the connecting shaft through a second bearing.

[0014] According to the above technical solution, the steel pipe transfer device provided by this utility model has the following beneficial effects during use:

[0015] Firstly, when there is a gap between the steel pipe and the ground, the semi-ring bracket and the semi-ring auxiliary frame can form a complete ring. When there is no gap between the steel pipe and the ground, there will be a gap between the semi-ring bracket and the semi-ring auxiliary frame. However, the width of this gap will be smaller than the diameter of the steel pipe. Therefore, the end of the steel pipe can be tilted upward and placed into the semi-ring bracket without the assistance of another person, which can improve the handling efficiency and make it more practical.

[0016] Secondly, when the steel pipe needs to be unloaded, tilt the semi-circular bracket to make it contact the ground. The steel pipe can still push the semi-circular auxiliary frame away by its own rolling force, or you can manually move away from the semi-circular bracket and rotate the semi-circular auxiliary frame, and the steel pipe will roll off the semi-circular bracket, making the unloading operation convenient.

[0017] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0027] like Figure 1-4 As shown, a steel pipe transfer device includes: a connecting frame 2 with support wheels 1 at both ends; a support shaft 3 perpendicular to the connecting frame 2 in its length direction and mounted in the middle of the connecting frame 2 via a first bearing; a semi-ring bracket 4 fixedly connected to the top of the support shaft 3 in its middle; a semi-ring auxiliary frame 6 connected to one end of the semi-ring bracket 4 via a rotating shaft 5 parallel to the axis of the semi-ring bracket 4; an extension arm 7 fixedly connected to the connecting frame 2; a handle 27 mounted on the end of the extension arm 7 away from the connecting frame 2; and a control unit for driving the semi-ring auxiliary frame 6 to rotate closer to the semi-ring bracket 4. The control unit includes a pull handle 8 slidably mounted on the end of the extension arm 7 away from the connecting frame 2.

[0028] In the above technical solution, when in use, holding handle 27 drives the connecting frame 2 to rotate, and the semi-ring bracket 4 will tilt. The end of the semi-ring bracket 4 away from the rotating shaft 5 moves to the bottom side of the steel pipe. Then, pulling the handle 8 drives the control unit to start, so that the semi-ring auxiliary frame 6 rotates around the rotating shaft 5 and approaches the semi-ring bracket 4. If there is a gap between the steel pipe and the ground, the semi-ring bracket 4 and the semi-ring auxiliary frame 6 can form a complete ring, and the end of the steel pipe can be tilted upward and fall into the semi-ring bracket 4. If there is no gap between the steel pipe and the ground, there will be a gap between the semi-ring bracket 4 and the semi-ring auxiliary frame 6. However, the width of the gap will be smaller than the diameter of the steel pipe, so the end of the steel pipe can also be tilted upward and fall into the semi-ring bracket 4. Then, release the handle 8. This not only makes it more convenient to use, but even if there is no gap between the end of the steel pipe and the ground, a single person can transfer the end of the steel pipe to the semi-ring bracket 4 without the assistance of another person, which can improve the handling efficiency and make it more practical.

[0029] When the steel pipe needs to be unloaded, tilt the semi-ring bracket 4 to make it contact the ground and release the handle 8. The steel pipe can be pushed away by the thrust of its own rolling motion, or the semi-ring auxiliary frame 6 can be manually rotated away from the semi-ring bracket 4, and the steel pipe will roll off the semi-ring bracket 4. The operation is convenient when unloading.

[0030] The rotating shaft 5 is rotatably connected to the end of the semi-ring bracket 4 and fixedly connected to the end of the semi-ring auxiliary frame 6. The control unit also includes a transmission disc 9 slidably sleeved on the support shaft 3, a transmission mechanism assembled on the transmission disc 9 and connected to the rotating shaft 5, at least one sliding arm 10 parallel to the support shaft 3 and sliding through the connecting frame 2 along its own length direction, a transmission component 11 fixedly connected to one end of the sliding arm 10 and having a U-shaped cross-section, slidably sleeved on the edge of the transmission disc 9, a first guide 12 assembled on the side of the connecting frame 2 away from the semi-ring bracket 4, a connector 13 fixedly connected to the end of the sliding arm 10 away from the transmission component 11, and a pull rope 14 with one end fixedly connected to the connector 13 and the other end sliding through the first guide 12 and connected to the handle 8.

[0031] In the above technical solution, pulling the handle 8 will move the connecting piece 13 away from the semi-ring bracket 4 via the pull rope 14, causing the sliding arm 10 to slide on the connecting frame 2. The transmission piece 11 will drive the transmission disc 9 to slide away from the semi-ring bracket 4 on the support shaft 3. The transmission disc 9 will drive the rotating shaft 5 to rotate via the transmission mechanism, thereby causing the semi-ring auxiliary frame 6 to rotate around the rotating shaft 5 and approach the semi-ring bracket 4.

[0032] The transmission component 11 is slidably sleeved on the edge of the transmission disc 9, so during the handling process, the support wheel 1 can be driven to adjust the direction by the handle 27. Because the steel pipe is pressed on the semi-ring bracket 4, the support shaft 3 will rotate relative to the connecting frame 2 to adjust the handling direction.

[0033] The transmission mechanism includes a gear 15 coaxially fixedly sleeved on a rotating shaft 5, a turntable 16 mounted on the outer wall of a semi-ring bracket 4 via a connecting shaft parallel to the rotating shaft 5, an inclined first connecting arm 17 with one end hinged to the turntable 16 via a first hinge shaft parallel to the connecting shaft and away from the gear 15, and a second connecting arm 18 with both ends hinged to the middle of the first connecting arm 17 and the transmission disk 9 via second hinge shafts respectively.

[0034] The turntable 16 has a meshing part 19 on its side wall that meshes with the gear 15. The end of the first connecting arm 17 away from the turntable 16 is inclined to the transmission disk 9, and the end of the second connecting arm 18 away from the transmission disk 9 is inclined to the support shaft 3.

[0035] The upper surface of the first connecting arm 17 away from the end of the turntable 16 is provided with a first strip-shaped through groove 20 of the same length direction for the support shaft 3 to pass through. The side wall of the first connecting arm 17 away from the end of the turntable 16 is provided with a second strip-shaped through groove 21 of the same length direction and communicating with the first strip-shaped through groove 20. A first guide bolt 22 passing through the second strip-shaped through groove 21 is fixedly connected to the support shaft 3.

[0036] In the above technical solution, the transmission disk 9 slides away from the semi-ring bracket 4 on the support shaft 3, and the first connecting arm 17 is moved by the second connecting arm 18. The side wall of the second strip-shaped through groove 21 slides against the first guide bolt 22. The end of the second strip-shaped through groove 21 near the first hinge shaft moves closer to the first guide bolt 22. The distance between the first hinge shaft and the support shaft 3 is shortened. The first connecting arm 17 will drive the turntable 16 to rotate around the connecting shaft. The meshing part 19 will drive the gear 15 to rotate, thereby driving the rotating shaft 5 and the semi-ring auxiliary frame 6 to rotate.

[0037] The end of the extension arm 7 away from the connecting frame 2 is provided with a third strip-shaped through groove 23 of the same length direction, and a second guide bolt 24 that slides through the third strip-shaped through groove 23 is fixedly connected to the handle 27.

[0038] In the above technical solution, the third strip groove 23 and the second guide bolt 24 limit the sliding range of the handle 8 in the extension arm 7, and can also control the distance between the handle 8 and the handle 27 when the handle 8 is released, so that the handle 8 can be pulled next time.

[0039] The extension arm 7 is equipped with at least one second guide 25 through which the pull rope 14 slides.

[0040] A pair of mounting seats 26 are fixedly connected to the outer wall of the semi-ring bracket 4, which are spaced apart along the axis of the semi-ring bracket 4. The two ends of the connecting shaft are respectively mounted on the pair of mounting seats 26, and the turntable 16 is mounted on the connecting shaft through a second bearing.

[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0043] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
