Description

Technical Field

[0001] This utility model relates to the technical field of water channel cover hoisting equipment, and in particular to a water channel cover hoisting device. Background Technology

[0002] Drainage canal covers, also known as sewer covers or manhole covers, were originally made primarily of traditional materials such as cement and cast iron. However, these materials are prone to damage over long-term use, leading to frequent replacements and increased maintenance costs. Nowadays, drainage canal covers are mostly made of steel grating processed through pressure welding. This method offers advantages such as simple installation, light weight, good load-bearing capacity, and strong impact resistance.

[0003] Chinese patent CN220764483U discloses a lifting clamp for orchard drainage ditch covers. However, this clamp still requires manual support to accurately position the cover between its two clamps, and manual assistance is also needed during disassembly, lacking automated vertical lifting capabilities. Furthermore, from an applicability standpoint, this lifting clamp is more suited to covers made of traditional materials such as cement and cast iron, with relatively limited compatibility with newer steel grating covers. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a canal cover hoisting device.

[0005] The technical solution of this utility model is achieved through the following scheme: a water channel cover hoisting device, including a supporting body, a pushing part, a gantry hoisting frame, a hanging device and a supporting component. The supporting body is provided with a pushing part at one end. A plurality of gantry hoisting frames are arrayed across the top surface of the supporting body. A hanging device is slidably installed on the gantry hoisting frame. The supporting body and the pushing part are slidably connected to the supporting component. The gantry hoisting frame is connected to the steel grating plate through the hanging device.

[0006] Through the above technical solutions, several gantry-type lifting frames are arrayed across the top surface of the supporting body, forming multiple lifting channels. The sliding hanging device on the gantry-type lifting frame allows the device to move flexibly and adapt to different working positions, improving lifting efficiency and flexibility. Before lifting, the support component is located in the pushing part to protect the workers in the pushing part. After the lifting is stable, the support component moves to the supporting body to provide auxiliary support for the steel grating, which significantly improves the operation efficiency of the canal cover lifting and reduces the operation difficulty and labor cost.

[0007] Preferably, the hoisting device includes an electric hoist, a wire rope, and a lifting mechanism. The telescopic end of the electric hoist is fixedly connected to the lifting mechanism via the wire rope, and the electric hoist is slidably installed on the gantry hoisting frame.

[0008] Preferably, the lifting mechanism includes an upper support plate, a lower support plate, a sleeve, and a lower connecting rod. One end of the lower connecting rod is fixedly connected to the bottom of the wire rope, and the other end of the lower connecting rod is fixedly connected to the lower support plate. The upper support plate is movably mounted on the lower connecting rod through the sleeve.

[0009] Through the above technical solutions, the introduction of electric hoists reduces the difficulty of manual operation, making the hoisting process more labor-saving and easier to control. The wire rope, as the transmission medium connecting the electric hoist and the lifting mechanism, has high strength, wear resistance, and corrosion resistance, ensuring stability and safety during hoisting. The upper and lower support plates can rotate into a straight line or a cross shape. The straight line facilitates passing through the square holes of the steel grating, while the cross shape facilitates locking after passing through. Combined with the wire rope, this effectively improves the stability and safety of the hoisting process, allowing multiple steel grating panels to be directly suspended and lowered, avoiding the problem of manual disassembly piece by piece, and reducing labor intensity and costs.

[0010] Preferably, the support assembly includes a drive motor, a slide rail, and a support plate. The drive motor is fixedly mounted on the support plate, and the support plate is slidably mounted on the slide rail via the drive motor.

[0011] Preferably, both the supporting body and the pushing part are provided with slides, the slides are provided with racks, and the drive end of the drive motor is equipped with gears that mesh with the racks.

[0012] Through the above technical solution, the rotation of the drive motor drives the gear to roll on the rack, thereby realizing the sliding of the support plate. In conjunction with the hanging device, it achieves strong and automated support for the canal cover, improving work efficiency and safety. The design of the support component allows the support plate to slide and adjust as needed, so that it can be in different positions at different working times of the lifting device, thus performing different functions. For example, during the lifting, the push part provides protection to reduce the impact of the lifting sway on the workers; after the lifting is completed, it slides into the main bearing position for auxiliary support.

[0013] Preferably, the portal frame includes support columns and I-beams. The support columns are symmetrically installed on the load-bearing body, the I-beams are fixedly installed on the top surfaces of the two support columns, and the hanging device is slidably installed on the I-beams.

[0014] Preferably, the supporting body and the pushing part are integrated, and the bottom surface of the supporting body is provided with a brake wheel.

[0015] Through the above technical solutions, the gantry crane adopts a combination design of support columns and I-beams to ensure the stability and load-bearing capacity of the crane. At the same time, the integrated design of the load-bearing body and the propulsion unit also improves the overall structural stability and reliability. The bottom surface of the load-bearing body is equipped with brake wheels, which facilitates the movement and positioning of the crane device when needed.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses an array of portal-type lifting frames spanning the top surface of the supporting body to form multiple lifting channels. The sliding hanging device on the portal-type lifting frames allows the device to move flexibly and adapt to different working positions, improving lifting efficiency and flexibility. Before lifting, the support component is located in the pushing part to protect the workers in the pushing part. After the lifting is stable, the support component moves to the supporting body to provide auxiliary support for the steel grating. This significantly improves the operation efficiency of water channel cover lifting and reduces the operation difficulty and labor cost.

[0018] 2. The introduction of electric hoists reduces the difficulty of manual operation, making the hoisting process more labor-saving and easier to control. The wire rope, as the transmission medium connecting the electric hoist and the lifting mechanism, has high strength, wear resistance, and corrosion resistance, ensuring stability and safety during hoisting. The upper and lower support plates can rotate into a straight line or a cross shape. The straight line facilitates passing through the square holes of the steel grating, while the cross shape facilitates locking after passing through. Combined with the wire rope, this effectively improves the stability and safety of the hoisting process, allowing multiple steel grating panels to be directly suspended and lowered, avoiding the problem of manual disassembly piece by piece, and reducing labor intensity and costs.

[0019] 3. The rotation of the drive motor drives the gears to roll on the rack, thereby enabling the sliding of the support plate. This, combined with the hanging device, provides strong and automated support for the canal cover, improving work efficiency and safety. The design of the support components allows the support plate to slide and adjust as needed, so that it can be in different positions at different times of the lifting device to perform different functions. For example, during the lifting process, the push part provides protection to reduce the impact of swaying on the workers; after the lifting is completed, it slides into the main support position for auxiliary support.

[0020] 4. The gantry crane adopts a combination design of support columns and I-beams to ensure the stability and load-bearing capacity of the crane. At the same time, the integrated design of the load-bearing body and the propulsion unit also improves the overall structural stability and reliability. The bottom of the load-bearing body is equipped with brake wheels to facilitate the movement and positioning of the lifting device when needed. Attached Figure Description

[0032] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] A canal cover hoisting device, such as Figure 1-10As shown, the system includes a supporting body 1, a pushing unit 2, a gantry-type lifting frame 3, a hanging device 4, and a supporting assembly 5. The supporting body 1 has a pushing unit 2 at one end. Several gantry-type lifting frames 3 are arrayed across the top surface of the supporting body 1. Hanging devices 4 are slidably installed on the gantry-type lifting frames 3. Both the supporting body 1 and the pushing unit 2 are slidably connected to the supporting assembly 5. The gantry-type lifting frames 3 are connected to the steel grating 7 via the hanging devices 4. Preferably, there are two gantry-type lifting frames 3 and four hanging devices 4. Two hanging devices 4 are installed on each of the two gantry-type lifting frames 3 to hang the steel grating 7 at its four corners, ensuring balanced load distribution. The moving part 2 is an integral part, and the bottom surface of the supporting body 1 is equipped with a brake wheel 6. The pushing part 2 is inclined on the supporting body 1. In order to prevent the supporting component 5 from obstructing the hanging device 4 from hanging the steel grating 7, the supporting component 5 is retracted at the pushing part 2 during the hanging process, so that the two do not interfere with each other. At this time, the staff can stand behind the pushing part 2 for effective protection, avoiding the danger of collision caused by the shaking of the steel grating 7 during the hanging process. After the hanging is stable, the supporting component 5 slides down to provide further support, distributing the force on the hanging device 4, increasing the stability of the device's movement, and improving the overall service life of the device. The brake wheel 6 can effectively fix the device.

[0035] The hoisting device 4 includes an electric hoist 41, a wire rope 42, and a lifting mechanism 43. The telescopic end of the electric hoist 41 is fixedly connected to the lifting mechanism 43 via the wire rope 42. The electric hoist 41 is slidably mounted on the gantry crane 3. The electric hoist 41 can be adjusted on the gantry crane 3 to accommodate steel grating panels 7 of different sizes and lengths. The lifting mechanism 43 includes an upper support plate 431, a lower support plate 432, a sleeve 433, and a lower connecting rod 434. One end of the lower connecting rod 434 is fixedly connected to the bottom of the wire rope 42, and the other end of the lower connecting rod 434 is fixedly connected to a lower... Support plate 432 and upper support plate 431 are movably mounted on lower connecting rod 434 via sleeve 433. Both lower support plate 432 and upper support plate 431 are elongated. Sleeve 433 is sleeved on lower connecting rod 434. Each side of sleeve 433 has an upper support plate 431. Sleeve 433 can rotate 90° around lower connecting rod 434 so that lower support plate 432 and upper support plate 431 intersect to form a cross shape. Upper support plate 431 and lower support plate 432 can pass through square holes in steel grating 7 and be adjusted to form a cross shape, engaging with the square holes for support.

[0036] The support assembly 5 includes a drive motor 51, a slide rail 52, and a support plate 53. The drive motor 51 is fixedly mounted on the support plate 53, and the support plate 53 is slidably mounted on the slide rail 52 via the drive motor 51. The support plate 53 is in the shape of a large-hole grid plate, which facilitates the insertion and passage of the upper support plate 431 and the lower support plate 432. It plays different roles in different positions, assisting in support during movement and protecting workers during suspension.

[0037] When the steel grating 7 is transferred and unloaded as a whole, the support plate 53 returns to the push part 2 via the drive motor, and controls the electric hoist 41 to lower the steel grating 7 until it is placed on the wooden sleeper in the new storage location. The four pairs of upper support plates 431 and lower support plates 432 are screwed back into a straight shape, and the lifting mechanism 43 is lifted by the electric hoist 41. At this time, the unloading and transfer of multiple steel gratings 7 are completed.

[0038] When the plate is unloaded at the location where it needs to be installed, the lifting mechanism 43 is continuously lowered. At this time, the support plate 53 provides the main support, and the lifting mechanism 43 naturally sags after losing its load. The support plate 53 is a certain distance from the ground. At this time, the pushing part 2 is in an open state. The staff can easily manually adjust the upper support plate 431 and the lower support plate 432 back to a straight line at the pushing part 2. The electric hoist 41 is used to store them, and the restriction of the hanging device 4 is removed. Then, the plate can be unloaded one by one for the installation of the water channel cover.

[0039] Both the supporting body 1 and the pushing part 2 are provided with slide rails 52, and racks are laid in the slide rails 52. The drive end of the drive motor 51 is equipped with gears, which mesh with the racks. At the square holes at the four corners of the support plate 53, drive motors 51 are fixedly installed on the opposite slide rails 52, preferably four in number, for driving. When the device is not working, the support plate 53 is in the supporting body 1 and is laid flat. When it is being hoisted, the drive motors 51 drive the support plate 53 into the pushing part 2 of the inclined part. After the hoisting is stable, it will return to the supporting body 1, which greatly improves the service life of the racks and pinions.

[0040] The gantry-type hoisting frame 3 includes support columns 31 and I-beams 32. The support columns 31 are symmetrically installed on the load-bearing body 1, and the I-beams 32 are fixedly installed on the top surfaces of the two support columns 31. The hanging device 4 is slidably installed on the I-beams 32. The load-bearing body 1 is composed of two parallel strip steels. One end is connected by an inclined gantry-type pusher 2, and the other end is an open storage area for pushing in and parking the steel grating 7. The two support columns 31 are respectively fixed on the two parallel strip steels and connected by the horizontally placed I-beams 32. At this time, the entire load-bearing body 1 is connected and fixed, and its movement is stable.

[0041] Working principle: The staff pushes the entire device until it reaches the storage area of ​​the steel grating 7, and then starts the drive motor 51 of the support component 5, which drives the support plate 53 into the push part 2. At this time, the front end of the device is open, and the steel grating 7 is easily put into the hanging area of ​​the device. The hanging device 4 is then adjusted according to the size of the steel grating 7, and the steel wire rope 42 is lowered so that the end support mechanism 43 passes through the square hole of the steel grating 7. At this time, the upper support plate 431 and the lower support plate 432 of the support mechanism 43 are manually adjusted to change from a straight line to a cross shape.

[0042] At this time, the lifting mechanism 43 engages with the square hole of the steel grating plate 7, and the electric hoist 41 collects and hangs it. After the hanging is stable, the drive motor 51 drives the support plate 53 back to the main body 1 for auxiliary support to ensure stable lifting operation. When the plate is transferred to the position for unloading, it can be easily unloaded by reversing the order of operations, without having to remove each plate individually.

[0043] When storing the steel grating 7, a wooden pillow will be placed at the bottom to keep it a certain distance from the ground. This distance is sufficient for workers to reach in and manually adjust the upper support plate 431 and the lower support plate 432. All parts and equipment use conventional models in the prior art, and the circuit connection uses conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
