Description

Technical Field

[0001] This application relates to the field of medical device installation technology, specifically a tube hoisting tool and hoisting device. Background Technology

[0002] The X-ray tube is a core component of CT equipment. To ensure image quality, the X-ray tube typically needs to be replaced after 1-2 years of use. Weighing approximately 100 kg, the tube is quite heavy. Currently, tube replacement mainly relies on manual handling and installation by maintenance personnel. This operation is not only labor-intensive and inefficient but also poses significant safety hazards, easily causing damage to workers and the tube. Although forklifts can be used to assist in installation, reducing labor intensity and improving efficiency, hospital CT rooms are often located underground or on upper floors, making forklift access inconvenient. Furthermore, the limited space in the room restricts the use of forklifts.

[0003] A search revealed that a utility model with publication number CN210944597U proposes a CT tube auxiliary installation device, whose support structure is non-foldable and requires a large amount of space for transportation. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application proposes a hoisting fixture and hoisting device for a sphere tube.

[0005] A hoisting fixture for a ball tube includes an auxiliary frame, which includes a base and columns installed at the four corners of the base. The columns have strap holes on their surfaces, allowing straps to pass through the columns and form a restraint fence around the auxiliary frame, thus limiting the displacement of the ball tube during hoisting.

[0006] The upper surface of the base is provided with a placement groove, and the surface of the placement groove is provided with a limiting groove. The limiting groove is fitted with a baffle. After the ball tube is installed, the baffle is inserted into the limiting groove to restrict the movement of the ball tube.

[0007] A lifting ring is installed at the top of the column. The height of the lifting ring depends on the height of the column. The height of the column must ensure that the wire rope does not come into direct contact with the ball tube during hoisting and installation. The shape of the placement groove corresponds to the shape of the ball tube.

[0008] A cyclone tube hoisting device includes a fixed frame, a lead screw inside the fixed frame, including a threaded section in the middle of the lead screw and smooth sections at both ends of the lead screw, and a support vertical arm rotatably connected to the fixed frame. The support vertical arm includes a first support arm and a retractable second support arm nested in the first support arm, which together form a retractable support vertical arm for adjusting the hoisting height of the device.

[0009] Furthermore, the lower half of the first support arm is cylindrical and the upper half is a rectangular cube. The inner surface of the first support arm is threaded and mates with the smooth section at the top of the lead screw.

[0010] Furthermore, the first support arm and the second support arm have corresponding adjustment holes on their surfaces. When working, after extending a specified distance, fixing pins or fastening bolts are installed in them to limit the relative displacement between the first support arm and the second support arm.

[0011] Furthermore, a connector is fixedly connected to the top of the second support arm, and the connector is connected to a boom. The boom consists of an outer boom, a middle boom, and an inner boom. The boom is a telescopic structure, with the outer boom nested inside the middle boom, and the middle boom nested inside the inner boom. Adjustment holes are opened on the surface of the boom, and the adjustment holes are fitted with fixing pins or fastening bolts. The vertical height is adjustable to adapt to different machine room heights.

[0012] Furthermore, the bottom end of the first support arm penetrates the upper surface of the fixed seat frame, and a limiter is provided at the connection between the bottom end of the first support arm and the fixed seat frame. The first support arm is slidably connected to the inner surface of the limiter. It also includes a fixing pin that penetrates the bottom surface of the first support arm and the surface of the limiter, fixing the first support arm and connecting the first support arm to the limiter at the same time. A bearing is provided between the limiter and the fixed seat frame, so that the limiter can rotate relative to the fixed seat frame.

[0013] Furthermore, when the device needs to be transported, remove the fixing pins or fastening bolts in the adjustment holes on the boom and support arm, compress the support arm and boom to their shortest state, and insert fixing pins or fastening bolts into the corresponding adjustment holes to limit them and prevent them from shaking and extending during transportation.

[0014] The bottom end of the lead screw extends out of the fixed seat frame, and a turntable is detachably connected to the bottom end of the lead screw. A bearing is installed between the bottom end of the lead screw and the fixed seat frame. The operator removes the fixing pin in the limiter, and the support vertical arm moves downward under the action of gravity until the bottom contacts the top of the lead screw. At this time, the smooth section at the top of the lead screw extends into the support vertical arm. It should be noted that in the unfolded state, the smooth section at the top of the lead screw should extend into the support vertical arm. If the first support arm extends too far when unfolded, it will cause the bottom of the first support arm to detach from the top of the lead screw.

[0015] The operator rotates the turntable and applies downward pressure to the support arm, causing the internal thread of the support arm to engage with the threaded end of the lead screw. The rotation of the lead screw drives the support arm to move downward until the support arm is fully retracted, at which point the device reaches its lowest height.

[0016] Furthermore, both the connector and the boom surface are provided with positioning holes and rotating shaft holes, and the positions of the holes correspond one to one. The positioning holes and rotating shaft holes are used to fix pins or fastening bolts. During hoisting operations, the positioning holes and rotating shaft holes serve to fix and limit the movement.

[0017] Furthermore, during transportation, in order to further reduce the space occupied by the device, the fixing pin in the positioning hole and the rotating shaft hole is removed. At this time, the connector and the boom are connected only by a fixing pin installed in the rotating shaft hole. The boom can rotate at a certain angle with the fixing pin in the rotating shaft hole as the rotating axis. In order to ensure that the boom can rotate, the rotating shaft hole is set on the side of the connector near the cantilever end.

[0018] Furthermore, in order to accommodate the rotation of the boom, a receiving groove adapted to the boom is provided at the top of the second support arm and on the fixed seat frame to accommodate the boom after rotation. The receiving groove is also equipped with a corresponding baffle.

[0019] Furthermore, the rotation range of the boom can be changed by extending or shortening the length of the connector and by setting rotating shaft holes at different positions on the connector.

[0020] Furthermore, an angle adjustment assembly is provided inside the fixed seat frame. The angle adjustment assembly includes a first worm gear fixedly connected to the outer surface of the bottom end of the first support arm. The first worm gear meshes with a first worm. One end of the first worm is rotatably connected to the inner surface of the fixed seat frame, and the other end is fitted with a worm support seat installed on the inner surface of the fixed seat frame. A bearing is provided between the first worm and the worm support seat. The end of the first worm near the worm support seat extends out of the fixed seat frame and is connected to a hand crank.

[0021] Furthermore, in the working state, the first support arm is separated from the lead screw, and the first support arm is fixedly connected to the limiter through a fixed pin. At this time, shaking the hand crank turnstable drives the first worm to rotate, which in turn drives the first worm wheel to rotate through meshing, thereby driving the first support arm to rotate. The limiter is sleeved on the outer surface of the first support arm and is rotatably connected to the fixed seat frame to reduce rotational resistance and adjust the angle. At the same time, the self-locking characteristics of the worm wheel and worm are used to achieve angle self-locking.

[0022] Furthermore, it also includes a roller assembly, which includes a winch assembly detachably mounted on the first support arm, and rollers mounted at both ends of the boom. The two ends of the boom include a cantilever end for lifting equipment and a fixed end detachably connected to a connector. One end of the winch is wound with a steel wire, and the other end of the steel wire passes through the roller and is located at the cantilever end of the boom. A hook is installed at the end of the steel wire located at the cantilever end.

[0023] Furthermore, the winch assembly includes a self-locking unit, which comprises a second worm gear and a second worm that mesh with each other inside the winch assembly housing. One end of the second worm is rotatably connected to the inner surface of the winch assembly, and the other end is fitted with a worm support seat to support the rotation of the second worm. A bearing is provided between the second worm and the worm support seat. One end of a connecting post is connected to the shaft of the second worm gear, and the other end of the connecting post extends out of the winch assembly housing and is connected to the reel. The connecting post drives the second worm gear and the reel's keyway, and the connecting post is rotatable.

[0024] An inclined support is connected between the support arm and the boom. The two ends of the inclined support are respectively provided with fixing holes corresponding to the adjustment holes on the surface of the support arm and the boom, and are equipped with fastening bolts. Depending on the specific situation, shims or pads are provided for connection and fastening.

[0025] The bottom of the fixed seat frame is equipped with lockable casters.

[0026] Compared with the prior art, this application has the following beneficial effects:

[0027] By setting strap holes and limiting grooves, and using straps and baffles to restrict the tube, the stability of the tube during hoisting is ensured.

[0028] The telescopic support vertical arm and nested boom structure, combined with the roller assembly, enable mechanized hoisting of the X-ray tube, avoiding the strength burden and safety hazards of manually handling heavy X-ray tubes. At the same time, the configuration of vertical arm compression, boom rotation and bottom casters allows the device to flexibly enter and exit the space-constrained underground or upstairs CT room, overcoming the site limitations where forklifts cannot be used.

[0029] During transportation, the vertical arm is compressed to its lowest height through a screw linkage mechanism, and the boom is rotated and stored, which greatly reduces the volume and solves the problem of transportation space occupation caused by the fixed structure of existing devices.

[0030] Furthermore, the device achieves precise angle adjustment and stable locking of the supporting vertical arm through a worm gear self-locking mechanism, ensuring reliable hoisting process; the self-locking unit built into the winch assembly prevents the ball tube from accidentally falling during hoisting.

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0049] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] Example 1

[0051] like Figure 1-2 As shown, a hoisting fixture for a ball tube includes an auxiliary frame 14. The auxiliary frame 14 includes a base 1401 and columns 1402 installed at the four corners of the base 1401. The surface of the columns 1402 is provided with strap holes 1403, so that the straps 1410 pass through the columns 1402 to form a restraint fence around the auxiliary frame 14, thereby restricting the displacement of the ball tube 1409 during the hoisting process.

[0052] The upper surface of the base 1401 is provided with a placement groove 1404, and the surface of the placement groove 1404 is provided with a limiting groove 1407. The limiting groove 1407 is fitted with a baffle 1406. After the ball tube 1409 is installed, the baffle 1406 is inserted into the limiting groove 1407 to restrict the movement of the ball tube.

[0053] The top of the column 1402 is provided with a lifting ring 1405. The height of the lifting ring 1405 depends on the height of the column 1402. The height of the column 1402 must ensure that the wire rope does not directly contact the surface of the tube 1409 during hoisting and installation. The shape of the placement groove 1404 corresponds to the outer contour of the tube.

[0054] Example 2

[0055] like Figure 2-3 As shown, a cyclone tube hoisting device includes a fixed frame 1, inside which a lead screw 10 is provided. The lead screw 10 includes a threaded section in the middle and smooth sections at both ends. The fixed frame 1 is rotatably connected to a support vertical arm 3. The support vertical arm 3 includes a first support arm 301 and a retractable second support arm 302 nested within the first support arm 301. The first support arm 301 and the second support arm 302 are nested together to form the retractable support vertical arm 3, which is used to adjust the hoisting height of the device.

[0056] The lower half of the first support arm 301 is cylindrical and the upper half is rectangular cube. The inner surface of the first support arm 301 is threaded and engages with the smooth section at the top of the lead screw 10.

[0057] The first support arm 301 and the second support arm 302 have corresponding adjustment holes 7 on their surfaces. When working, after the second support arm 302 extends a specified distance from the first support arm 301, a fixing pin 15 or a fastening bolt 24 is installed in the adjustment hole 7 to limit the relative displacement between the first support arm 301 and the second support arm 302.

[0058] The second support arm 302 is fixedly connected to a connector 5, and the connector 5 is connected to a boom 6. The boom 6 is a telescopic structure composed of an outer arm, a middle arm and an inner arm. Specifically, the outer arm is nested inside the middle arm and the middle arm is nested inside the inner arm. An adjustment hole 7 is opened on the surface of the boom 6, and a fixing pin 15 or a fastening bolt 24 is fitted into the adjustment hole 7.

[0059] The bottom end of the first support arm 301 penetrates the upper surface of the fixed seat frame 1. A limiter 23 is provided at the connection between the bottom end of the first support arm 301 and the fixed seat frame 1. It also includes a fixing pin 15 that penetrates the bottom surface of the first support arm 301 and the surface of the limiter 23. While fixing the first support arm 301, the first support arm 301 is connected to the limiter 23. A bearing 25 is provided between the limiter 23 and the fixed seat frame 1 so that the limiter 23 can rotate relative to the fixed seat frame 1.

[0060] When the device needs to be transported, remove the fixing pins 15 or fastening bolts 24 from the adjustment holes 7 on the boom 6 and the support arm 3, compress the support arm 3 and the boom 6 to their shortest state, and insert the fixing pins 15 or fastening bolts 24 into the adjustment holes 7 at the corresponding positions to limit them and prevent them from shaking and extending during transportation.

[0061] The bottom of the lead screw 10 extends out of the fixed seat frame 1 and is detachably connected to the turntable 11. A bearing is provided between the bottom of the lead screw 10 and the fixed seat frame 1. The operator removes the fixed pin 15 in the limiter 23, and the support vertical arm 3 moves downward under the action of gravity until the bottom contacts the top of the lead screw 10. At this time, the smooth section at the top of the lead screw 10 extends into the support vertical arm 3. It should be noted that when the lead screw 10 is in the unfolded state, the smooth section at the top of the lead screw 10 should extend into the support vertical arm 3. If the first support arm 301 is extended too much when unfolded, the bottom of the first support arm 301 will detach from the top of the lead screw 10.

[0062] The operator rotates the turntable 11 and applies downward pressure to the support arm 3, causing the internal thread of the support arm 3 to engage with the threaded end of the lead screw 10. The rotation of the lead screw 10 drives the support arm 3 to move downward until the support arm 3 is fully retracted, at which point the device height reaches its minimum.

[0063] Example 3

[0064] like Figure 8-12 Based on Embodiment 1, a ball tube hoisting device is provided, wherein the connecting member 5 and the boom 6 are provided with positioning holes 901 and rotating shaft holes 902 on their surfaces, and the positions of the holes correspond one to one. The positioning holes 901 and rotating shaft holes 902 are used to fix pins 15 or fastening bolts 24. During hoisting work, the positioning holes 901 and rotating shaft holes 902 both play the role of fixing and limiting.

[0065] During transportation, in order to further reduce the space occupied by the device, the fixing pin 15 in the positioning hole 901 and the rotating shaft hole 902 is removed. At this time, the connector 5 and the boom 6 are connected only by a fixing pin 15 installed in the rotating shaft hole 902. At this time, the boom 6 can rotate at a certain angle with the fixing pin 15 in the rotating shaft hole 902 as the rotation axis. In order to ensure that the boom 6 can rotate, the rotating shaft hole 902 is set on the side of the connector 5 near the cantilever end.

[0066] Furthermore, in order to accommodate the rotation of the boom 6, a receiving groove adapted to the boom 6 is provided on the top of the second support arm 302 and on the fixed seat frame 1 to accommodate the boom 6 after rotation. At the same time, the receiving groove is equipped with a corresponding baffle.

[0067] Furthermore, the rotation range of the boom 6 can be changed by extending or shortening the length of the connector 5 and by setting rotating shaft holes 902 at different positions on the connector 5.

[0068] Example 4

[0069] like Figure 5-7 , Figure 15As shown in Embodiment 1, a cyclone tube hoisting device is provided. The fixed frame 1 is provided with an angle adjustment component. The angle adjustment component includes a first worm gear 17 disposed on the outer surface of the bottom end of the first support arm 301. The first worm gear 17 is engaged with a first worm 16. One end of the first worm 16 is rotatably connected to the inner surface of the fixed frame 1, and the other end is engaged with a worm support seat 27 installed on the inner surface of the fixed frame 1. A bearing 25 is disposed between the first worm 16 and the worm support seat 27. The end of the first worm 16 near the worm support seat 27 extends out of the fixed frame 1 and is connected to a hand crank turntable 20.

[0070] In the working state, the first support arm 301 is separated from the lead screw 10. The first support arm 301 is fixedly connected to the limiter 23 through the fixed pin 15. At this time, the hand crank 20 drives the first worm 16 to rotate, which drives the first worm wheel 17 to rotate through meshing, thereby driving the first support arm 301 to rotate. The limiter 23 is sleeved on the outer surface of the first support arm 301 and is rotatably connected to the fixed seat frame 1 to reduce rotational resistance and adjust the angle. At the same time, the self-locking characteristic of the worm wheel and worm is used to achieve angle self-locking.

[0071] It also includes a roller assembly, which includes a winch assembly detachably mounted on the first support arm 301 and rollers 8 mounted at both ends of the boom 6. The boom 6 has cantilever ends for lifting equipment and fixed ends detachably connected to the connector 5. One end of the winch is wound with steel wire, and the other end of the steel wire passes through the rollers 8 and is located at the cantilever end of the boom 6. A hook is installed at the end of the steel wire located at the cantilever end.

[0072] The winch assembly includes a self-locking unit, which comprises a second worm gear 18 and a second worm 19 meshing with each other inside the winch assembly housing. One end of the second worm 19 is rotatably connected to the inner surface of the winch assembly, and the other end is fitted with a worm support seat 27 to support the rotation of the second worm 19. A bearing is provided between the second worm 19 and the worm support seat 27. One end of a connecting post 29 is axially connected to the second worm gear 18, and the other end of the connecting post 29 extends out of the winch assembly housing and is connected to a reel 28. The connecting post 29 is keyway driven by the second worm gear 18 and the reel 28. The connecting post 29 is rotatably disposed inside a connecting post support seat 26, which is mounted on the inner surface of the winch assembly housing.

[0073] A driving component is connected to one end of the second worm 19 near the worm support 27. In this embodiment, the driving component is a hand-cranked turntable 20, which is connected to the second worm 19 via screws and a keyway. By rotating the hand-cranked turntable 20, the second worm 19 is rotated, causing the second worm wheel 18 to drive the wire reel to rotate and reel in and out of the wire.

[0074] An inclined support member 21 is connected between the supporting vertical arm 3 and the hanging arm 6. The two ends of the inclined support member 21 are respectively provided with fixing holes corresponding to the adjustment holes 7 on the surface of the supporting vertical arm 3 and the hanging arm 6, and are equipped with fastening bolts 24. Depending on the specific situation, a pad 30 or a shim 31 is provided for connection and fastening.

[0075] The bottom of the fixed frame 1 is equipped with lockable casters 12.

[0076] It also includes an auxiliary frame 14, which includes a base 1401 and columns 1402 installed at the four corners of the base 1401. The surface of the columns 1402 is provided with strap holes 1403.

[0077] The upper surface of the base 1401 is provided with a placement groove 1404, and the top of the column 1402 is provided with a lifting ring 1405. The height of the lifting ring 1405 depends on the height of the column 1402. The height of the column 1402 must ensure that the wire rope does not directly contact the ball tube during hoisting and installation. The shape of the placement groove 1404 corresponds to the shape of the ball tube.

[0078] Example 5

[0079] like Figure 13-14 As shown, a tube hoisting device replaces the fixed seat frame 1 with a clamp 22, further reducing the overall height of the device. At the same time, the clamp 22 can be directly clamped to the edge of a hospital bed or other objects with a certain thickness, making it convenient to use. The clamp 22 includes an upper clamping plate 2201 and a lower clamping plate 2202. The surfaces of the upper clamping plate 2201 and the lower clamping plate 2202 are provided with a friction layer to help clamp the bed board. However, when using the clamp 22 to replace the fixed seat frame 1, it is necessary to ensure stability and add counterweights if necessary to prevent tipping during hoisting.
