Description

Technical Field

[0001] The utility model specifically relates to a feeding hoist. Background Art

[0002] Metal bar materials are used in various industries. According to the requirements of users, manufacturers will cut the metal bar materials into different lengths. Since the medium and large-sized metal bar materials are large in shape and heavy in weight, it is very laborious for manufacturers to load the metal bar materials. Therefore, users have invented an automatic metal bar material loading device. For example, the "Automatic Lifting Mechanism for Metal Round Bar Materials" disclosed in Chinese Patent CN200910181835.0 pre-places the metal bar materials in a material box and transports the metal bar materials through chains provided on an upper sprocket and a lower sprocket, with conveying hooks provided on the chains, saving labor and improving production efficiency.

[0003] When users use the feeding hoist to feed metal bar materials, due to the large weight of the metal bar materials, during the transportation process, and the lifting mechanism is a chain and sprocket mechanism for lifting, it is inevitable to have jitter. After long-term use, it is inevitable that the chain will break. If there is still a metal bar material on the conveying hook when the chain breaks, it is very dangerous and has very serious potential safety hazards. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a feeding hoist aiming at the deficiencies of the above-mentioned prior art.

[0005] To achieve the above object, the utility model provides the following technical solution: A feeding hoist includes a mounting frame. One end of the mounting frame is a placement end, and the other end is a conveying end. A lifting assembly is provided on the mounting frame, and it is characterized in that: the lifting assembly includes a hydraulic cylinder, the hydraulic cylinder is installed on the mounting frame, a clamping fixture component is arranged on the output end of the hydraulic cylinder, and the hydraulic cylinder drives the reciprocating movement of the clamping fixture component.

[0006] With the above technical solution, usually when a user uses a loading hoist, a feeder is equipped and applied to a cutting machine. The metal bar stock is placed on the loading hoist in an orderly manner. When the loading hoist is in the initial state, the hydraulic cylinder is in a contracted state. When the feeder needs the metal bar stock, the hydraulic cylinder rises, thereby driving the fixture component to move upward. The fixture component drives the metal bar stock to move upward. When it moves to the top, the gravity generated by the metal bar stock itself is converted into rolling force. The metal bar stock rolls onto the conveying end and is then guided by the conveying end to the feeder; subsequently, the hydraulic cylinder retracts, thereby driving the fixture component to move downward, causing the fixture component to contact the metal bar stock, causing the fixture component to rotate, and causing the hydraulic cylinder to complete the recovery; replacing the chain and sprocket lifting component provided in the traditional loading hoist with a hydraulic cylinder-based lifting component avoids the left and right shaking of the lifting component when moving up and down, improves the safety of the user using the loading hoist, and improves the service life at the same time.

[0007] Replacing the chain and sprocket lifting component provided in the traditional loading hoist with a hydraulic cylinder-based lifting component, when installing the hydraulic cylinder, only need to align the reserved hole provided at one end of the hydraulic cylinder with the installation hole on the mounting frame, and connect the other end to the fixture component to complete the installation of the hydraulic cylinder; when the hydraulic cylinder is damaged, only need to replace the original hydraulic cylinder to complete the installation. If the height of the loading hoist is too high, there is no need to rely on other tools. Only need to control the hydraulic cylinder to retract to easily complete the disassembly and installation of the hydraulic cylinder, reducing the installation and maintenance difficulty of the loading hoist.

[0008] The above-mentioned loading hoist can be further set as: the fixture component includes a sliding plate and a clamping plate device arranged on the sliding plate. The sliding plate is connected to the output end of the hydraulic cylinder. The clamping plate device includes a limiting column, a rotating column, and a clamping plate. The rotating column is arranged on the sliding plate. The middle of the clamping plate is sleeved on the rotating column, so that the clamping plate is rotatably installed on the sliding plate. The clamping plate is divided into a limiting end and a receiving end along the center of the rotating column. The limiting column is arranged above the limiting end, so that the limiting column is clamped and linked with the clamping plate. The receiving end extends out of the sliding plate.

[0009] With the above technical solution, in the initial state, the hydraulic cylinder is in a contracted state, so that the clamping plate device is located below the metal bar stock. When the user controls the hydraulic cylinder to rise and move upward, one end of the clamping plate is in contact with the metal bar stock. Since the limiting end and the limiting column are in contact with each other, a counteracting force is generated. At this time, the counteracting force is greater than the gravity of the metal bar stock, driving the metal bar stock to move upward. When the movement stops, due to the guidance of the clamping plate device, the gravity generated by the metal bar stock itself is converted into rolling force. The metal bar stock rolls onto the conveying end and is then guided by the conveying end to the feeder; subsequently, the hydraulic cylinder retracts and moves downward, causing the clamping plate to contact the metal bar stock to generate a counteracting force. At this time, the clamping plate rotates counterclockwise along the rotating column, and then the recovery can be completed;

[0010] When the user installs the clamping plate device, only need to insert and install the limit post and the rotating post on the sliding plate, and then sleeve the clamping plate on the rotating post to complete the installation; the installation difficulty is reduced.

[0011] The above-mentioned feeding hoist can be further set as: a connecting component is provided between the hydraulic cylinder and the sliding plate, the connecting component includes a ball eye joint and an insertion shaft, the ball eye joint is installed on the hydraulic cylinder, and the insertion shaft passes through the ball eye joint and is inserted into the sliding plate, so that the hydraulic cylinder and the sliding plate are inserted and connected.

[0012] Adopting the above technical solution, with a connecting component provided between the hydraulic cylinder and the sliding plate, when connecting the hydraulic cylinder and the sliding plate, the user only needs to install the ball eye joint on the hydraulic cylinder, and then pass the insertion shaft through the ball eye joint and insert it into the sliding plate to complete the connection between the hydraulic cylinder and the sliding plate, further reducing the installation difficulty; when the hydraulic cylinder is damaged, only need to pull out the insertion shaft to complete the separation of the hydraulic cylinder and the sliding plate, and then disassemble the ball eye joint to replace the hydraulic cylinder, reducing the maintenance difficulty and further reducing the maintenance cost, which is beneficial to the popularization and application of the feeding hoist.

[0013] The above-mentioned feeding hoist can be further set as: synchronous hole positions are opened on the clamping plate, and the synchronous hole positions are arranged on the receiving end; the receiving end is provided with a clamping portion.

[0014] Adopting the above technical solution, when the user sets multiple feeding hoists to be linked, when the user controls the feeding hoist to lift the metal rod material, through the synchronous hole positions provided on the clamping plate, synchronous connecting pieces are inserted into the synchronous hole positions, so that the fixture assembly can lift the metal rod material more stably, avoiding the metal rod material from tilting during the lifting process, and improving the stability of the feeding hoist; by setting the clamping portion, the clamping portion is arranged in a three-step shape. When the metal rod material is received by the clamping plate, the metal rod material will roll inward along the gravity. When the material is lifted and vibrates, the metal rod material will inevitably bounce. When bouncing, the clamping portion will have a counteracting effect on the metal rod material to avoid the metal rod material from detaching, improving the safety of the user using the feeding hoist.

[0015] The above-mentioned feeding hoist can be further set as: a sliding component is provided between the sliding plate and the mounting frame, the sliding component includes a slide rail and a slider, the slide rail is installed on the mounting frame, the lower end of the slider is slidably installed on the slide rail, and the upper end of the slider is connected to the sliding plate.

[0016] With the above technical solution, the slider is installed on the slide rail to achieve smooth movement of the slider along the direction of the slide rail. The slider has a high load capacity and can bear the gravity from the fixture component and the metal rod stock and remain stable, reducing the gravity burden when the hydraulic cylinder pushes the sliding plate upward, while enhancing the action precision when the hydraulic cylinder moves upward or downward and reducing the noise during sliding; it is also very convenient to install the slider slide rail and has no installation difficulty.

[0017] The above-mentioned loading hoist can be further set as: the clamping plate device includes a fixed limiting member, one end of the fixed limiting member is connected to the limiting column and the other end is connected to the rotating column.

[0018] With the above technical solution, when the user controls the hydraulic cylinder to drive the sliding plate to move upward or downward, the clamping plate device and the metal rod stock exert a counteracting force, and at this time, a certain vibration force will be generated. As the use time goes by, it is inevitable that the clamping plate device will become loose. By providing a fixed limiting member on the limiting column and the rotating column, the connection relationship between the limiting column, the clamping plate and the sliding plate is further stabilized, improving the working stability of the loading hoist and the working efficiency.

[0019] The above-mentioned loading hoist can be further set as: the loading hoist includes a protective member, the protective member is inserted into the mounting frame, the protective member is arranged between the placing end and the conveying end, and the outer peripheral surface of the protective member is in contact connection with the conveying end.

[0020] With the above technical solution, when the user controls the hydraulic cylinder to push the fixture component upward, the fixture component drives the metal rod stock to move upward. Since the metal rod stock needs to be closely attached to the conveying end when moving upward for the loading hoist to stably lift the metal rod stock, usually there is a relatively rough protective layer on the surface of the metal rod stock, which will generate friction with the mounting frame when moving upward, thereby accelerating the wear of the mounting frame and reducing the service life of the mounting frame. By providing a protective member between the placing end and the conveying end, when the metal rod stock moves upward, the metal rod stock is in contact with the protective member. If the protective member is damaged, the user can pull out the protective member and replace it with a new one to continue using the loading hoist. Through this setting, while improving the service life of the loading hoist, the maintenance cost of the loading hoist is reduced; when the user controls the hydraulic cylinder to push the fixture component upward, the fixture component drives the metal rod stock to move upward. Due to the gravity, the subsequent metal rod stock will roll along the direction of the placing end, and it is inevitable that the metal rod stock will collide with the mounting frame, resulting in damage to the mounting frame. By providing a protective member between the placing end and the conveying end, the direct collision between the metal rod stock and the mounting frame is avoided, further improving the service life of the mounting frame and the user experience.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 to 6 shown, a feeding hoist includes an installation frame 1. One end of the installation frame 1 is a placing end 11, and the other end is a conveying end 12. A lifting assembly 20 is provided on the installation frame 1. It is characterized in that: the lifting assembly 20 includes a hydraulic cylinder 201. The hydraulic cylinder 201 is installed on the installation frame 1. A fixture part 60 is arranged on the output end of the hydraulic cylinder 201. The hydraulic cylinder 201 drives the reciprocating movement of the fixture part 60.

[0032] Generally, when a user uses a loading hoist, a feeder is equipped and applied to a cutting machine 2. The metal bar stock 3 is orderly placed on the loading hoist. When the loading hoist is in the initial state, the hydraulic cylinder 201 is in the contracted state. When the feeder needs the metal bar stock 3, the hydraulic cylinder 201 rises, thereby driving the fixture component 60 to move upward. The fixture component drives the metal bar stock 3 to move upward. When it moves to the top, the gravity generated by the metal bar stock 3 itself is converted into rolling force, and the metal bar stock 3 rolls onto the conveying end 12 and is then guided to the feeder 2 by the conveying end 12. Subsequently, the hydraulic cylinder 201 retracts, thereby driving the fixture component 60 to move downward, prompting the fixture component 60 to contact the metal bar stock 3, prompting the fixture component 60 to rotate, and prompting the hydraulic cylinder 201 to complete the recovery. The chain and sprocket lifting assembly originally provided on the traditional loading hoist is replaced with a lifting assembly 20 mainly composed of the hydraulic cylinder 201, which avoids the left and right shaking of the lifting assembly 20 during the up and down movement, improves the safety of the user using the loading hoist, and improves the service life at the same time.

[0033] The chain and sprocket lifting assembly originally provided on the traditional loading hoist is replaced with a lifting assembly mainly composed of the hydraulic cylinder 201. When installing the hydraulic cylinder 201, only the reserved hole provided at one end of the hydraulic cylinder 201 needs to be aligned with the installation hole on the mounting bracket 1, and the other end is connected to the fixture component 60, then the installation of the hydraulic cylinder 201 can be completed. When the hydraulic cylinder 201 is damaged, only the original hydraulic cylinder 201 needs to be replaced to complete the installation. If the height of the loading hoist is too high, no other tools are needed. Only by controlling the hydraulic cylinder 201 to retract, the disassembly and installation of the hydraulic cylinder 201 can be easily completed, reducing the installation and maintenance difficulty of the loading hoist.

[0034] The fixture component 60 includes a sliding plate 202 and a clamping plate device 30 provided on the sliding plate 202. The sliding plate 202 is connected to the output end of the hydraulic cylinder 201. The clamping plate device 30 includes a limiting column 301, a rotating column 302, and a clamping plate 303. The rotating column 302 is provided on the sliding plate 202. The middle of the clamping plate 303 is sleeved on the rotating column 302, so that the clamping plate 303 is rotatably installed on the sliding plate 202. The clamping plate 303 is divided into a limiting end 304 and a receiving end 305 along the center of the rotating column. The limiting column 301 is provided above the limiting end 304, so that the limiting column 301 is clamped and linked with the clamping plate 303. The receiving end 305 extends out of the sliding plate 202.

[0035] In the initial state, the hydraulic cylinder 201 is in a contracted state, causing the clamping plate device 30 to be located below the metal rod 3. When the user controls the hydraulic cylinder 201 to rise and move upward, one end of the clamping plate 303 comes into contact with the metal rod 3. Since the limiting end 304 and the limiting column 301 are in contact with each other, a counteracting force is generated. At this time, the counteracting force is greater than the gravity of the metal rod 3, driving the metal rod 3 to move upward. When the movement stops, due to the guidance of the clamping plate device 30, the gravity generated by the metal rod 3 itself is converted into rolling force, and the metal rod 3 rolls onto the conveying end 12 and is then guided by the conveying end 12 to the feeder 2; subsequently, the hydraulic cylinder 201 retracts and moves downward, causing the clamping plate 303 to contact the metal rod 3 to generate a counteracting force. At this time, the clamping plate 303 rotates counterclockwise along the rotating column 302, and then the recycling can be completed.

[0036] When the user installs the clamping plate device 30, only need to insert and install the limiting column 301 and the rotating column 302 on the sliding plate 202, and then sleeved the clamping plate 303 on the rotating column 302 to complete the installation; the installation difficulty is reduced.

[0037] A connection component is provided between the hydraulic cylinder 201 and the sliding plate 202. The connection component includes a spherical eye joint 402 and an insertion shaft 401. The spherical eye joint 402 is installed on the hydraulic cylinder 201, and the insertion shaft 401 passes through the spherical eye joint 402 and is inserted into the sliding plate 202, so that the hydraulic cylinder 201 and the sliding plate 202 are inserted and connected.

[0038] By providing a connection component between the hydraulic cylinder 201 and the sliding plate 202, when connecting the hydraulic cylinder 201 and the sliding plate 202, the user only needs to install the spherical eye joint 402 on the hydraulic cylinder 201, and then pass the insertion shaft 401 through the spherical eye joint 402 and insert it into the sliding plate 202 to complete the connection between the hydraulic cylinder 201 and the sliding plate 202, further reducing the installation difficulty; when the hydraulic cylinder 201 is damaged, only need to pull out the insertion shaft 401 to complete the separation of the hydraulic cylinder 201 and the sliding plate 202, and then disassemble the spherical eye joint 402 to replace the hydraulic cylinder 201, reducing the maintenance difficulty and further reducing the maintenance cost, which is beneficial to the popularization and application of the loading elevator.

[0039] Synchronous holes 306 are opened on the clamping plate 303, and the synchronous holes 306 are arranged on the receiving end 305; the receiving end 304 is provided with a clamping portion 307.

[0040] When the user sets multiple sets of feeding hoists in linkage, when the user controls the feeding hoist to lift the metal bar 3, through the synchronous holes 306 provided on the clamping plate 303, the synchronous connecting piece is inserted into the synchronous holes 306, so that the fixture assembly 60 can lift the metal bar 3 more stably, avoiding the inclination of the metal bar 3 during the lifting process, and improving the stability of the feeding hoist; by setting the clamping part 307, the clamping part 307 is arranged in a three-step shape. When the metal bar 3 is received by the clamping plate 303, the metal bar 3 will roll inward along with the gravity. When the material is lifted and vibrates, the metal bar 3 will inevitably bounce. When bouncing, the clamping part 307 and the metal bar 3 generate a counteracting effect, avoiding the metal bar 3 from detaching, and enhancing the safety of the user using the feeding hoist.

[0041] A sliding component 50 is provided between the sliding plate 202 and the mounting frame 1. The sliding component 50 includes a slide rail 501 and a slider 502. The slide rail 501 is mounted on the mounting frame 1, and the lower end of the slider 502 is slidably mounted on the slide rail 501. The upper end of the slider 502 is connected to the sliding plate 202.

[0042] The slider 502 is mounted on the slide rail 501, realizing the smooth movement of the slider 502 along the direction of the slide rail 501. The slider 502 has a high load capacity, can bear the gravity from the fixture component 60 and the metal bar 3 and maintain stability, reducing the gravity burden when the hydraulic cylinder 201 pushes the sliding plate 202 upward, and at the same time enhancing the action precision when the hydraulic cylinder 201 moves upward or downward and reducing the noise during sliding; it is also very convenient to install the slider 502 on the slide rail 501 and has no installation difficulty.

[0043] The clamping plate device 30 includes a limit fixing piece 6. One end of the limit fixing piece 6 is connected to the limit post 301 and the other end is connected to the rotating column 302.

[0044] When the user controls the hydraulic cylinder 201 to drive the sliding plate 202 to move upward or downward, the clamping plate device 30 and the metal bar 3 generate a counteracting force, and at this time, a certain vibration force will be generated. As the use time goes by, it is inevitable that the clamping plate device 30 will become loose. Through the limit fixing piece 6 provided on the limit post 301 and the rotating column 302, it is avoided that the clamping plate 303 and the rotating column 302 are separated when the user controls the feeding hoist to work, improving the stability of the feeding hoist during work and improving the work efficiency.

[0045] The feeding hoist includes a protection piece 503. The protection piece 503 is inserted into the mounting frame 1. The protection piece 503 is arranged between the placing end 11 and the conveying end 12, and the outer peripheral surface of the protection piece 503 is in contact connection with the conveying end 12.

[0046] The user controls the hydraulic cylinder 201 to push the fixture component 60 upward. The fixture component 60 drives the metal rod 3 to move upward. When the metal rod 3 moves upward, it is necessary to make the metal rod 3 closely adhere to the conveying end 12 so that the loading hoist can stably lift the metal rod 3. Usually, there is a relatively rough protective layer on the surface of the metal rod 3. When moving upward, it will generate friction with the mounting frame 1, thereby accelerating the wear of the mounting frame 1 and reducing the service life of the mounting frame 1. By providing a protective member 503 between the placing end 11 and the conveying end 12, when the metal rod 3 moves upward, the metal rod 3 contacts the protective member 503. If the protective member 503 is damaged, the user can pull out the protective member 503 and replace the protective member 503 to continue using the loading hoist. Through this setting, while improving the service life of the loading hoist, the maintenance cost of the loading hoist is reduced; the user controls the hydraulic cylinder 201 to push the fixture component 60 upward. The fixture component 503 drives the metal rod 3 to move upward. Due to the gravitational force, the subsequent metal rod 3 will roll along the direction of the placing end 11, and it is inevitable that the metal rod 3 will collide with the mounting frame 1, resulting in damage to the mounting frame 1. By providing a protective member 503 between the placing end 11 and the conveying end 12, direct collision between the metal rod 3 and the mounting frame 1 is avoided, further improving the service life of the mounting frame 1 and enhancing the user experience.
