Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a fixed frame hoisting device. Background Art

[0002] During the construction and renovation of a reservoir, it is difficult to move the reservoir equipment manually due to its large size and weight, and lifting equipment is usually required for operation.

[0003] A hoisting device typically consists of a frame and a winch mechanism mounted on top of the frame. The winch mechanism has a wire rope and a clasp. The clasp is attached to the equipment to be hoisted, allowing it to be lifted by the hoisting device. The winch mechanism typically slides directly on the frame's rails and is driven by a motor. Due to the heavy weight of the winch mechanism, direct installation on the rails creates significant friction and requires a high-power motor to operate, making it inconvenient and requiring improvement. Utility Model Content

[0004] In order to solve the problem that when the winch lifting mechanism slides directly on the track of the frame, the friction is large and it needs to be driven by a large-power motor, which is relatively inconvenient, the utility model provides a fixed frame hoisting device.

[0005] The utility model provides a fixed frame hoisting device, which adopts the following technical solutions:

[0006] A fixed frame lifting device includes a fixed frame and a lifting device slidingly arranged on the fixed frame, the fixed frame has a sliding guide rail for the lifting device to slide, and also includes a sliding seat located between the sliding guide rail and the lifting device, the sliding seat slides on the sliding guide rail, and the lifting device is fixed to the sliding seat; the sliding seat includes a seat body and a plurality of rollers arranged on the seat body and abutting against the sliding guide rail.

[0007] By adopting the above technical solution, a sliding seat is set between the lifting device and the fixed frame, and the sliding seat has rollers, so that when the lifting device slides on the fixed frame, the relative movement mode between the two is changed from sliding to rolling, thereby reducing the friction between the two. Only a small driving force is needed to drive it to move. It is relatively easy to install a small-power motor to complete the movement of a large-mass lifting device.

[0008] Optionally, the seat body is provided with a sliding groove for the sliding guide rail to be inserted and slide; the rollers are arranged at intervals and rotated at the bottom of the sliding groove, the seat body is provided with limit strips on both sides of the sliding groove, and the sliding guide rail is provided with a limit groove that cooperates with the limit strip.

[0009] By adopting the above technical solution, due to the cooperation between the limiting strip and the limiting groove, the sliding seat is not likely to derail when sliding on the sliding guide rail, thereby improving the installation performance.

[0010] Optionally, the seat body is provided with a felt layer at the bottom of the sliding groove for lubricating the roller, the felt layer abuts against the roller, and the seat body is provided with an oiling structure for adding lubricating oil to the felt layer.

[0011] By adopting the above technical solution, the oiling structure can oil the felt layer, so that the felt layer is always moist. And because the roller and the felt layer are always in contact, when the sliding seat slides on the sliding guide rail, the felt layer can apply lubricating oil to the roller surface, thereby further reducing the friction between the roller and the sliding guide rail.

[0012] Optionally, the oiling structure includes an oil storage box and a drainage wire; a mounting groove for the oil storage box to slide horizontally and be inserted into the top of the seat body; the drainage wire connects the oil storage box and the felt layer; the seat body is provided with a drainage channel connecting the mounting groove and the sliding groove for the drainage wire to pass through.

[0013] By adopting the above technical solution, the structural form of the oiling structure is specifically disclosed, and the oil storage box can be detachably installed in the installation groove of the seat body, so that the oil storage box can be replenished when it is short of lubricating oil; and the lubricating oil is guided to penetrate into the felt layer through the drainage wire, so that the lubricating oil in the oil storage box can be slowly consumed, and the lubricating oil can be used for a longer time.

[0014] Optionally, the seat body is provided with a plug post on the inner side wall of the mounting groove, and the drainage channel is coaxially passed through the plug post; one end of the drainage wire is connected to the felt layer, and the other end thereof is connected to the end of the plug post; the oil storage box has an oil storage cavity, and the side wall of the oil storage box is provided with an oil filling nozzle for the entry of lubricating oil and an oil outlet for the insertion of the plug post.

[0015] By adopting the above technical solution, when the oil storage box is installed in the installation groove, the plug can be inserted into the oil storage cavity. At this time, the drainage wire can contact the lubricating oil in the oil storage cavity. The lubricating oil can penetrate into the drainage wire and penetrate into the felt layer through the drainage wire, so that the felt layer always remains moist, which is relatively simple.

[0016] Optionally, the oil storage box is provided with a sealing assembly at the oil outlet to prevent the lubricating oil from leaking out, and when the oil storage box is installed in the installation groove, the sealing assembly is opened to allow the lubricating oil to penetrate into the drainage wire.

[0017] By adopting the above technical solution and setting up a sealing assembly, when the oil storage box is not installed on the seat body, the sealing assembly can seal the oil outlet, making it difficult for the lubricating oil in the oil storage box to leak from the oil outlet, thereby facilitating refueling of the oil storage box.

[0018] Optionally, the sealing assembly includes a sealing plate and a compression spring that drives the sealing plate to block the oil outlet; the sealing plate and the compression spring are both arranged in the oil storage cavity; when the oil storage box is installed in the mounting groove, the plug passes through the oil outlet and drives the sealing plate to move toward the oil storage cavity.

[0019] By adopting the above technical solution, the structural form of the sealing assembly is specifically disclosed. When the oil storage box is not installed on the seat body, the compression spring can drive the sealing plate to block the oil outlet, so that the lubricating oil is not easy to leak out of the oil outlet. When the oil storage box is installed on the seat body, the plug is inserted into the oil outlet and drives the sealing plate to move, thereby opening the oil outlet. At this time, the lubricating oil in the oil outlet cavity can flow to the felt layer along the drainage wire, which is relatively simple.

[0020] Optionally, the oil storage box is provided with a sealing gasket at the oil outlet, and the sealing gasket abuts against the side wall of the plug post.

[0021] By adopting the above technical solution, when the oil storage box is installed on the seat body and the plug is inserted into the oil outlet, the sealing gasket can prevent the lubricating oil from leaking from the gap between the oil outlet and the outer wall of the plug, thereby improving the sealing ability.

[0022] In summary, the present invention has at least one of the following beneficial technical effects:

[0023] 1. A fixed frame hoisting device, wherein a sliding seat is provided between the lifting device and the fixed frame, and the sliding seat has rollers, so that the movement mode between the lifting device and the fixed frame changes from sliding to rolling, thereby reducing friction between the two;

[0024] 2. By providing a felt layer and an oiling structure, the oiling structure can oil the felt layer, and the felt layer contacts the roller so that the felt layer can apply lubricating oil to the roller surface, thereby further reducing the friction between the roller and the sliding guide rail;

[0025] 3. By setting a sealing assembly at the oil outlet of the oil storage box, when the oil storage box is not installed on the seat body, the compression spring can drive the sealing plate to block the oil outlet, so that the lubricating oil is not easy to leak out of the oil outlet.

[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] The embodiment of the utility model discloses a fixed frame hoisting device.

[0034] Reference Figure 1 A fixed frame hoisting device includes a fixed frame 1, a sliding base 2, and a lifting device 3. The fixed frame 1 is fixedly mounted on the ground at a construction site for installation of the lifting device 3. The lifting device 3 is used to lift the equipment to be hoisted. The lifting device 3 is mounted on the fixed frame 1 via the sliding base 2, thereby reducing friction between the lifting device 3 and the fixed frame 1.

[0035] The fixed frame 1 is a door-shaped structure, comprising two upright posts 11 and a horizontally arranged crossbeam 12 connecting the top ends of the two upright posts 11. A sliding guide rail 13 is arranged on the crossbeam 12 along its length.

[0036] The lifting device 3 includes a hoist 31, a wire rope 32 wound around the hoist 31, and a clasp 33 at the end of the wire rope 32. The lifting device 3 slides on top of the fixed frame 1. When lifting equipment, the clasp 33 is fixed to the equipment, and the hoist 31 drives the wire rope 32 to tighten, thereby lifting the equipment.

[0037] The fixed frame 1 is equipped with a drive mechanism 4 that drives the lifting device 3 to move horizontally. The drive mechanism 4 includes a drive motor 41, a drive screw 42, and a screw nut 43. The drive motor 41 is mounted on the top of the fixed frame 1. The drive screw 42 is arranged parallel to the crossbeam 12. The screw nut 43 is threaded onto the drive screw 42. The hoist 31 is mounted on top of the screw nut 43. The drive motor 41 can drive the drive screw to rotate, thereby allowing the hoist 31 and the screw nut 43 to slide on the drive screw 42.

[0038] Reference Figure 1 and Figure 2 The sliding seat 2 is arranged between the fixed frame 1 and the lifting device 3. The sliding seat 2 includes a seat body 21, a roller 22, a felt layer 23 and an oiling structure 24.

[0039] Reference Figure 2 and Figure 3 The seat body 21 is a rectangular parallelepiped structure, which is slidably mounted on the sliding guide rail 13. The seat body 21 is provided with a sliding groove 211, which is slidably matched with the sliding guide rail 13.

[0040] In order to prevent the seat body 21 from derailing when sliding on the sliding guide rail 13, the seat body 21 is symmetrically provided with limit bars 212 on the inner side wall of the sliding groove 211. The limit bars 212 are arranged along the length direction of the seat body 21. The sliding guide rail 13 is provided with limit grooves 131 on both sides, and the limit grooves 131 are engaged with the limit bars 212.

[0041] The roller 22 is rotatably mounted at the bottom of the sliding groove 211, with its rotation axis being horizontally disposed and perpendicular to the sliding direction of the seat 21. The roller 22 abuts against the top of the sliding guide rail 13, and when the sliding seat 2 slides on the sliding guide rail 13, the roller 22 can slide on the sliding guide rail 13.

[0042] In this embodiment, there are multiple rollers 22 and they are spaced apart along the length direction of the sliding groove 211 , so that the sliding seat 2 is more stable when installed on the sliding guide rail 13 through the rollers 22 .

[0043] The felt layer 23 is a square piece of fabric with good oil absorption. It is attached to the bottom of the sliding groove 211 by gluing. The felt layer 23 abuts the surface of the roller 22. As the roller 22 rolls on the sliding guide 13, the felt layer 23 applies lubricating oil to the surface of the roller 22, further reducing friction between the roller 22 and the sliding guide 13.

[0044] Reference Figure 3 and Figure 4 The oiling structure 24 is used to oil the felt layer 23 , and the oiling structure 24 includes an oil storage box 241 and a drainage wire 242 .

[0045] Reference Figure 4 and Figure 5 The oil storage box 241 is a hollow, square box with an oil storage cavity 2411 for storing lubricating oil. A grease nipple 2412 is provided on the sidewall of the oil storage box 241, through which the oil storage box 241 can be filled with oil. The oil storage box 241 can be disassembled for refilling, or an oil pipe can be connected to the grease nipple 2412 for real-time oil delivery. The sidewall of the oil storage box 241 is also provided with an oil outlet 2413 for discharging the lubricating oil.

[0046] To prevent the lubricating oil in the oil reservoir 241 from leaking out of the oil outlet 2413, the oil reservoir 241 is provided with a sealing assembly 2414 at the oil outlet 2413. The sealing assembly 2414 comprises a mounting cylinder 24141, a sealing plate 24142, and a compression spring 24143. The mounting cylinder 24141 is a central cylindrical body with one end open, fixedly mounted within the oil reservoir cavity 2411 and coaxially arranged with the oil outlet 2413. The mounting cylinder 24141 is provided with circumferential through-holes. The sealing plate 24142 is a circular plate with a diameter greater than that of the oil outlet 2413, and the sealing plate 24142 slides within the mounting cylinder 24141. The compression spring 24143 is disposed in the mounting tube 24141 , with one end thereof abutting against the mounting tube 24141 and the other end abutting against the blocking plate 24142 . The compression spring 24143 drives the blocking plate 24142 to always block the oil outlet 2413 .

[0047] A mounting groove 213 is defined on the top of the base body 21 , and the oil storage box 241 is horizontally slidably mounted in the mounting groove 213 .

[0048] Reference Figure 3 and Figure 5The base body 21 has a horizontally positioned post 214 on the inner wall of the mounting groove 213. A drainage channel 215 is defined within the base body 21. The post 214 coaxially passes through the drainage channel 215, connecting the mounting groove 213 and the sliding groove 211. A drainage wire 242 is positioned within the drainage channel 215, one end of which is connected to the felt layer 23 and the other end, tied and positioned at the end of the post 214.

[0049] When the oil storage box 241 is installed on the seat body 21, the plug 214 is inserted into the oil outlet 2413 and abuts against the sealing plate 24142. The plug 214 drives the sealing plate 24142 to overcome the elastic force of the compression spring 24143 and move toward the oil storage cavity 2411. At this time, the oil outlet 2413 is opened, and the lubricating oil in the oil storage cavity 2411 can enter the drainage channel 215 and penetrate into the felt layer 23 along the drainage wire 242, thereby moistening the felt layer 23.

[0050] When the oil storage box 241 is removed from the seat body 21 , the plug 214 withdraws from the oil outlet 2413 , and the blocking plate 24142 blocks the oil outlet 2413 again under the elastic force of the compression spring 24143 .

[0051] To prevent lubricating oil from leaking between the outer wall of the plug post 214 and the oil outlet 2413 when the oil reservoir 241 is mounted on the base 21, a sealing gasket 2415 is provided around the oil outlet 2413. When the plug post 214 is inserted into the oil outlet 2413, the sealing gasket 2415 abuts against the plug post 214, thereby improving the sealing performance.

[0052] The embodiment of the present invention provides a device for suspending a fixed frame 1, and the operating principle is as follows: a sliding seat 2 is provided between a lifting device 3 and the fixed frame 1. The sliding seat 2 includes a roller 22, a felt layer 23 for applying lubricating oil to the roller 22 in real time, and an oiling structure 24. When the sliding seat 2 slides on the sliding guide rail 13, the roller 22 rolls on the sliding guide rail 13 to reduce friction, and the lubricating oil applied to the roller 22 further reduces friction between the roller 22 and the sliding guide rail 13.

[0053] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
