Description

Technical Field

[0001] The present invention belongs to the technical field of hosting equipment, and in particular relates to a liftable hosting device. Background Art

[0002] Pipe beveling machines, combined with traditional conveyor rollers, can transport pipes to the appropriate location. However, for pipes longer than 15 meters, cranes and other lifting equipment are required, and cables are used to secure the outer side of the pipe. During transportation, the height of the pipe must be adjusted according to the equipment installation requirements. Existing pipe-lifting equipment has a simple structure and requires cables to secure the outer side of the pipe. This makes it prone to shifting or shaking during the pipe lifting process, and it is difficult to adjust the fixed size of the device according to the installation height and pipe diameter, resulting in a significant waste of time during the pipe lifting process.

[0003] The document with authorization announcement number CN211168744U discloses a high-finish hosting device, including a device base, a support rod, a positioning screw and a drive motor. A handle is connected to the top of the device base, and a first screw rod is connected to the top of the device base, an internally threaded rod is connected to the top of the first screw rod, a hosting wheel body is connected to the outside of the support rod, and a first support plate is connected to the bottom of the support rod, a connecting plate is connected to the top of the first support plate, and a second support plate is connected to the top of the connecting plate, a positioning screw is installed on the outside of the second support plate, and a clamping plate is provided directly above the second support plate, and a lifting handle is connected directly above the second support plate. The device uses a first screw rod and an internally threaded rod, and the first screw rod drives the internally threaded rod to slide vertically to adjust the height of the first support plate, ensuring the stability of the device during the lifting process.

[0004] However, the device still has the following parts that need to be improved: first, the part that directly supports the pipeline is only the hosting wheel body, which is subjected to high pressure and has a high loss rate; second, relative rolling and displacement may occur between the pipeline and the wheel body, which is inconvenient for pipeline connection; third, the lifting structure composed of the drive motor, the first screw rod and the internal threaded rod bears the entire weight of the clamping part above and the pipeline, the equipment has a large load, and the loss rate and maintenance rate are high. Summary of the Invention

[0005] In response to the above-mentioned problems, the purpose of the present invention is to provide a liftable hosting device. By setting a base plate, a U-shaped fixed frame, a lifting structure and a sliding frame, not only the lifting effect of the hosting device is achieved, but also the single load-bearing structure is eliminated on the basis of this effect, thereby reducing the loss of the load-bearing structure. At the same time, it can also be suitable for pipes of different lengths and diameters, and has the advantages of low maintenance rate, long service life, strong flexibility, high practicality and wide range of applications.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A liftable hosting device comprises a base plate, two U-shaped fixing frames arranged on one side of the base plate and opposite to each other, a lifting structure arranged on the other side of the base plate, and a sliding frame arranged between the two U-shaped fixing frames; the lifting structure comprises two threaded rods rotatably connected to the base plate, a driving motor arranged on the base plate and located between the two threaded rods, a driving gear connected to the output end of the driving motor, and two rotating gears fixed on the two threaded rods and respectively engaged with the driving gears; the sliding frame comprises a frame body, two sliding blocks arranged on both sides of the frame body and slidably connected to the U-shaped fixing frames, and two first threaded holes arranged on the side ends of the frame body and respectively connected to the two threaded rods.

[0008] As a further preferred embodiment of the present invention, it also includes a fixing plate arranged at the upper end of the frame, a circular hole arranged on one side of the fixing plate and used to insert the threaded rod, two clamping nuts arranged on the threaded rod and located on the upper and lower sides of the fixing plate, and an inverted U-shaped clamping plate arranged at the lower end of the fixing plate for clamping the pipe.

[0009] As a further preferred embodiment of the present invention, the frame includes a main body, a side groove provided on a side of the main body away from the first threaded hole, a carrier plate provided in the side groove, and a baffle provided on one side of the main body.

[0010] As a further preference of the present invention, the inverted U-shaped splint includes an inverted U-shaped base body, an opening arranged on the inverted U-shaped base body, a hanging rod arranged at the lower end of the fixed plate and used to be inserted into the opening, and a hanging plate arranged on the side of the inverted U-shaped base body away from the baffle.

[0011] As a further preferred embodiment of the present invention, the inverted U-shaped splint also includes a first groove arranged on the side end of the main body, a second threaded hole arranged on the lower end of the hanging plate, and a first fixing bolt screwed into the second threaded hole and with its end inserted into the first groove.

[0012] As a further preferred embodiment of the present invention, the inverted U-shaped clamp also includes a second groove arranged on the fixing plate, a third threaded hole arranged at the upper end of the inverted U-shaped seat body, and a second fixing bolt passing through the second groove and with its end threaded into the third threaded hole.

[0016] In summary, the present invention has the following beneficial effects:

[0017] The device of the present invention divides the structure used to support the weight of the equipment body and the pipeline into a U-shaped fixed frame and a lifting structure. Not only is the stability of the sliding frame significantly improved when it is raised and lowered, but more importantly, it replaces the single load-bearing structure, reduces the loss of the load-bearing structure, reduces the maintenance rate, and increases the service life.

[0018] The driving motor of the device of the present invention is not directly connected to the threaded rod as the load-bearing structure, thereby avoiding excessive load on the motor shaft and increasing the service life of the driving motor.

[0019] The distance between the fixing plate and the frame body of the device of the present invention is adjustable on the same threaded rod, so that the device can be applied to pipes of various diameters, thereby improving practicability.

[0020] The inverted U-shaped clamping plate of the device of the present invention can effectively clamp the upper curved surface of the pipeline after the relative positions of the fixed plate and the frame are determined, thereby preventing the pipeline from slipping and rolling on the frame, which is beneficial to the connection of the pipeline.

DETAILED DESCRIPTION

[0030] Example 1

[0032] The device also includes a fixing plate 501 arranged at the upper end of the frame 401, a circular hole 502 arranged on one side of the fixing plate 501 and used to insert the threaded rod 301, two clamping nuts 503 arranged on the threaded rod 301 and located on the upper and lower sides of the fixing plate 501, and an inverted U-shaped clamping plate 504 arranged at the lower end of the fixing plate 501 for clamping the pipe.

[0033] Compared with the existing equipment, the advantages of this device are: First, for the sliding frame 4 that carries the pipeline, the mechanism for supporting its body and the weight of the pipeline is divided into a U-shaped fixed frame 2 and a lifting structure 3, which not only significantly improves the stability of the sliding frame 4 when it is lifted and lowered, but more importantly, it replaces the single load-bearing structure, reduces the loss of the load-bearing structure, reduces the maintenance rate, and increases the service life; Second, the driving motor 302 of this device is not directly connected to the threaded rod 301 as the load-bearing structure, which avoids excessive load on the motor shaft and increases the service life of the driving motor; Third, the distance between the fixed plate 501 of this device and the frame 401 on the same threaded rod 301 is adjustable, so that it can be applied to pipelines of various diameters, which improves practicality; Fourth, the inverted U-shaped clamp 504 of this device can effectively clamp the arc surface of the pipeline after the relative position of the fixed plate 501 and the frame 401 is determined, thereby avoiding slipping and rolling of the pipeline on the frame 401, which is beneficial to the connection of the pipeline.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that the structures of the frame 401 and the inverted U-shaped clamping plate 504 are optimized. Figure 4 -Attached Figure 8 As shown, the details are as follows:

[0036] In this embodiment, the frame 401 includes a main body 401a, a side groove 401b arranged on the side of the main body 401a away from the first threaded hole 403, a carrier plate 401c arranged in the side groove 401b, a baffle 401d arranged on one side of the main body 401a, a channel 401e arranged in the carrier plate 401c, a limiting rod 401f arranged on the side wall of the side groove 401b and inserted into the channel 401e, and a handle 401g arranged on the side end of the carrier plate 401c.

[0037] The side groove 401b is provided at the upper end of the body 401a, and its longitudinal direction is aligned with the extension direction of the baffle 401d. After the carrier plate 401c is positioned within the side groove 401b, its upper surface is located at the same horizontal plane as the upper end of the side groove, thereby ensuring a smooth surface of the frame 401. The carrier plate 401c is movable horizontally through the insertion structure of the channel 401e and the limiting rod 401f. This allows the horizontal position of the pipe to be adjusted by pulling the carrier plate 401c after it is placed on the pipe, facilitating adjustment of the distance between the docking ports during pipe docking, thereby improving docking efficiency.

[0038] Among them, the baffle 401d is only arranged on the same side of the sliding block 402 at one end, and its purpose is to connect with the main body 401a to form an L-shaped load-bearing plate body. The advantage of the L-shaped load-bearing plate body is that when faced with a longer or heavier pipe that is not convenient to be placed on the plate body by transporting, the pipe can be rolled into the end where the baffle 401d is not set, thereby reducing the work intensity.

[0039] In this embodiment, the inverted U-shaped clamping plate 504 includes an inverted U-shaped base body 504a, an opening 504b provided on the inverted U-shaped base body 504a, a hanging rod 504c provided at the lower end of the fixing plate 501 and used to be inserted into the opening 504b, a hanging plate 504d provided on the side of the inverted U-shaped base body 504a away from the baffle 401d, a first groove 504e provided on the side end of the main body 401a, a second threaded hole 504f provided on the lower end of the hanging plate 504d, a first fixing bolt 504g screwed into the second threaded hole 504f and with its end inserted into the first groove 504e, a second groove 504h provided on the fixing plate 501, a third threaded hole 504i provided at the upper end of the inverted U-shaped base body 504a, and a second fixing bolt 504j passing through the second groove 504h and with its end screwed into the third threaded hole 504i.

[0040] The purpose of the plug-in structure between the opening 504b and the hanging rod 504c is to enable the horizontal adjustment of the inverted U-shaped clamp 504. The lower end of the hanging plate 504d extends all the way to the side of the body 401a and partially overlaps with it. The purpose is that after the pipe is placed inside the body 401a, the hanging plate 504d can act as a stopper opposite the baffle 401d, thereby preventing the pipe from rolling and sliding.

[0041] The connection structure of the first groove 504e, the first threaded hole 504f, and the first fixing bolt 504g is intended to achieve a locking function for the hanging plate 504d. This includes three aspects: first, locking the position of the inverted U-shaped clamp 504 to prevent it from sliding on the hanging plate 504c; second, locking the pipeline by pressing down to tighten the pipeline and prevent displacement; and finally, locking the carrier plate 401c. After the carrier plate 401c is positioned, the downward pressure exerted by the locked inverted U-shaped clamp 504 on the pipeline and the pipeline's own weight further act on the carrier plate 401c, thereby limiting the movement of the carrier plate 401c. The position locking of the above three aspects further improves the stability of the pipeline docking operation, thereby improving the efficiency of the pipeline docking. In addition, multiple first threaded holes 504f can be provided along the vertical direction to accommodate pipelines of different diameters.

[0042] The second groove 504h, the third threaded hole 504i, and the second fixing bolt 504j are designed to further tighten the inverted U-shaped clamping plate 504, thereby ensuring a stable clamping effect.

[0043] The structure of this embodiment is primarily used in the following scenarios: First, when the pipe is too long, a single pull on the carrier plate 401c may not be enough to horizontally displace the entire pipe (because the pipe portion outside the carrier plate 401c accounts for a larger portion). In this case, the pipe is clamped by the inverted U-shaped clamp 504, so that the friction between the contact portion of the carrier plate 401c and the pipe is greater than the friction between the non-contact portion. The inverted U-shaped clamp 504 clamps the pipe and moves with the carrier plate 401c, thereby dragging the pipe and finally locking it in position. Second, when the pipe is too short, it is necessary to place the pipe on the carrier plate 401c near the opening of the side groove 401b to facilitate pipe docking. In this case, the position of the inverted U-shaped clamp 504 is adjusted until it is located in the middle of the pipe, and finally locked in position to ensure that the clamping position does not shift, effectively locking the pipe and facilitating pipe docking. In addition, in the first scenario, the number of inverted U-shaped clamps 504 can be increased to improve the stability of the pipe.

[0044] The working principle of this embodiment is as follows: a. First, the frame 401 is lowered as a whole to the loading position by the driving motor 302. At this time, the distance between the fixed plate 501 and the frame 401 is much larger than the diameter of the pipe, and the hanging plate 504c does not affect the entry of the pipe. The pipe is pushed onto the carrier plate 401c, and then the position of the inverted U-shaped clamp 504 is adjusted until it is located above the middle of the pipe, and finally the height of the fixed plate 501 is adjusted until the inverted U-shaped clamp 504 clamps the pipe; b. The driving motor 302 drives the frame 401 to lift the pipe to the preset docking height, and then adjusts the docking distance of the pipe by pulling the carrier plate 401c (the inverted U-shaped clamp 504 moves horizontally on the hanging rod 504c with the carrier plate 401c). After the position is determined, tighten the first fixing bolt 504g and the second fixing bolt 504j to complete the fixation of the inverted U-shaped clamp 504, the carrier plate 401c and the horizontal position of the pipe. After the entire device is locked, the next step of pipe docking is carried out.
