Description

Technical Field

[0001] This utility model relates to the technical field of tarpaulin deployment and retraction equipment, and in particular to a wheeled chassis mast tarpaulin sealing device. Background Technology

[0002] In industrial production and logistics warehousing, open-air locations such as construction sites, cargo yards, and port terminals often require temporary covering and protection for goods, equipment, or work areas. For example, building materials and construction equipment at construction sites, if exposed to the open environment for extended periods, will suffer from rain erosion, sun exposure, and wind and sand erosion, leading to a decline in material performance, equipment damage, and impacting project quality and progress. Similarly, various goods in cargo yards, especially environmentally sensitive materials such as grains, textiles, and precision instruments, also require covering and protection to ensure their quality and safety.

[0003] Traditional methods of taking down and deploying tarpaulins rely heavily on manual operation. This manual operation is extremely labor-intensive, especially for large tarpaulins, which require multiple people to work together, consuming a lot of manpower and time. Furthermore, manual operation is inefficient and cannot respond quickly to sudden situations such as weather changes. For example, in the event of sudden rain, goods or equipment may get wet if the tarpaulins are not deployed or deployed in time. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the traditional method of tarpaulin deployment and retrieval mostly relies on manual operation, which is extremely labor-intensive, especially for large-area tarpaulins, requiring multiple people to work together, consuming a lot of manpower and time. In addition, manual operation is inefficient and difficult to respond quickly to sudden situations such as weather changes. For example, in the event of sudden rain, goods or equipment may get wet due to the failure to deploy or retrieval the tarpaulin in time. Therefore, a wheeled chassis mast tarpaulin sealing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wheeled chassis mast canopy covering device includes a wheeled vehicle body, a slewing support assembly fixedly installed on the upper surface of the wheeled vehicle body, a mounting shell fixedly installed on the upper surface of the slewing support assembly, an electric push rod fixedly installed inside the mounting shell, a mast fixedly installed at the top of the drive shaft of the electric push rod, and a hoisting mechanism for hoisting the tarpaulin fixedly installed at the top of the mast via a mounting frame. The hoisting mechanism includes a drive motor rotatably mounted on the outer wall of the mounting frame, a hoisting roller fixedly mounted on the end of the output shaft of the drive motor, a fixed disc fixedly sleeved on the hoisting roller, and a servo motor. The servo motor is fixedly mounted on the inner wall of the mounting frame, and the output shaft of the servo motor passes through the mounting frame and is fixedly connected to the housing of the drive motor.

[0006] Preferably, the surface of the slewing support assembly is provided with a protective mechanism for covering the hoisting mechanism.

[0007] Preferably, the protective mechanism includes two rotating rods and two protective plates respectively fixedly sleeved on the two rotating rods. A first T-shaped plate is fixedly installed on the surface of the mounting shell. The surface of the first T-shaped plate has symmetrically opened rotation openings. The two rotating rods are respectively rotatably installed in the two rotation openings. The two rotating rods are controlled to rotate relative to each other by a threaded assembly.

[0008] Preferably, the threaded assembly includes a second T-shaped plate and two threaded rods vertically fixedly mounted on the upper surface of the second T-shaped plate. The threads on the surfaces of the two threaded rods are opposite in direction. The bottom end of the rotating rod is provided with a threaded groove, and the top ends of the two threaded rods are respectively threaded into the two threaded grooves. An L-shaped mounting plate is fixedly mounted on the lower surface of the rotary support assembly. The surface of the mounting plate is provided with a lifting component for controlling the vertical movement of the second T-shaped plate.

[0009] Preferably, the lifting component includes a telescopic cylinder fixedly mounted on the upper surface of the mounting plate, and the drive shaft of the telescopic cylinder is fixedly connected to the bottom of the second T-shaped plate.

[0010] Preferably, a sealing layer is adhered to the contact surfaces of the two protective plates, and the sealing layer is made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The wheeled vehicle body facilitates the movement of the equipment between different work locations, improving the equipment's flexibility and applicability. The liftable mast can be adjusted in height according to actual needs to adapt to different height covering requirements. Combined with the slewing support component, the covering position of the tarpaulin can be flexibly adjusted to meet the usage needs in different scenarios. The hoisting mechanism can control the release and retraction of the tarpaulin by rotating the hoisting rollers, reducing manual labor intensity and improving work efficiency. When the tarpaulin is in the winding state on the winch roller, the drive motor and winch roller can be rotated to a state parallel to the mast by the servo motor, thereby reducing the overall space occupied by the device and making it easy to move. When the device is not in use, and both the drive motor and the winch roller are rotated to be parallel to the mast, the two protective plates in the protective mechanism can be controlled to rotate relative to each other until they come into contact, thus covering the drive motor, the winch roller, and the tarpaulin rolled up on the winch roller, which can protect the winch mechanism and the tarpaulin.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figures 1-3 A wheeled chassis mast canopy covering device includes a wheeled vehicle body 1. A slewing support assembly 2 is fixedly installed on the upper surface of the wheeled vehicle body 1 (the slewing support assembly 2 is widely used in the field of engineering machinery, such as excavators, cranes, and aerial work platforms, to realize the slewing motion of the upper part relative to the lower part. It is an existing mature mechanical component, and its working principle will not be described in detail here). A mounting shell 3 is fixedly installed on the upper surface of the slewing support assembly 2. An electric push rod is fixedly installed inside the mounting shell 3. A mast 4 is fixedly installed at the top of the drive shaft of the electric push rod. A hoisting mechanism for hoisting the tarpaulin is fixedly installed at the top of the mast 4 through a mounting bracket 5.

[0017] Reference Figure 7The hoisting mechanism includes a drive motor 6 rotatably mounted on the outer wall of the mounting frame 5, a hoisting roller 7 fixedly mounted on the end of the output shaft of the drive motor 6, a fixed disc 8 fixedly sleeved on the hoisting roller 7, and a servo motor 9. A rain cloth is wrapped around the hoisting roller 7, and the servo motor 9 is fixedly mounted on the inner wall of the mounting frame 5. The output shaft of the servo motor 9 passes through the mounting frame 5 and is fixedly connected to the housing of the drive motor 6.

[0018] The wheeled vehicle body 1 serves as the mobile carrier for the equipment, enabling it to be quickly moved to a designated location. The lifting function of the mast 4 is achieved through an electric push rod inside the mounting housing 3. When it is necessary to adjust the tarpaulin coverage height, the electric push rod is activated, and its drive shaft extends and retracts in the vertical direction, causing the mast 4 to rise and fall synchronously. For low-profile goods or work areas, the mast 4 is controlled to descend to the corresponding height. For higher equipment or stacked goods, the mast 4 is driven to rise to match the covering requirements, ensuring that the tarpaulin can accurately cover the target area.

[0019] The slewing support assembly 2 connects the wheeled vehicle body 1 and the mounting shell 3. When it is necessary to adjust the tarpaulin coverage position, the slewing support assembly 2 drives the mounting shell 3, mast 4 and the top winch mechanism to rotate as a whole. The rotation angle can be adjusted within the range of 0°-360° according to actual needs, effectively eliminating blind spots and adapting to the protection needs of areas with different shapes.

[0020] When the tarpaulin needs to be released, the drive motor 6 rotates forward, driving the winch roller 7 to rotate synchronously. The tarpaulin rolled up on the roller slowly unfolds. When the tarpaulin is rolled up, the drive motor 6 rotates in reverse, and the winch roller 7 rotates in the opposite direction to wrap and retract the tarpaulin. The whole process does not require manual dragging and can be operated by a single person. The work efficiency is 3-5 times higher than that of manual methods.

[0021] When the tarpaulin is rolled up and the equipment is not in use, the servo motor 9 is started. Its output shaft drives the drive motor 6 and the winch roller 7 to rotate around the connection point of the mounting frame 5. Since the fixed plate 8 is fixedly sleeved with the winch roller 7, it rotates synchronously with the roller body until the drive motor 6, the winch roller 7 and the rolled-up tarpaulin are in a parallel state with the mast 4. At this time, the horizontal dimension of the equipment is reduced by about 40%. The wheeled vehicle body 1 is easier to pass through narrow passages or doorways during movement, and the space occupied during storage is significantly reduced, making it convenient to store in limited areas such as warehouses.

[0022] Reference Figures 4-6The surface of the slewing support assembly 2 is provided with a protective mechanism to cover the hoisting mechanism. The protective mechanism includes two rotating rods 10 and two protective plates 11 respectively fixedly sleeved on the two rotating rods 10. A first T-shaped plate 12 is fixedly installed on the surface of the mounting shell 3. The surface of the first T-shaped plate 12 has symmetrically opened rotation openings. The two rotating rods 10 are respectively rotatably installed in the two rotation openings. The relative rotation of the two rotating rods 10 is controlled by a threaded assembly. The threaded assembly includes a second T-shaped plate 13 and two vertically fixed rods installed on the second T-shaped plate 13. The surface of the threaded rod 14 has two threaded rods 14 with opposite thread directions. The bottom end of the rotating rod 10 is provided with a threaded groove 15. The top ends of the two threaded rods 14 are respectively threaded into the two threaded grooves 15. An L-shaped mounting plate 16 is fixedly installed on the lower surface of the rotary support assembly 2. The surface of the mounting plate 16 is provided with a lifting component for controlling the vertical movement of the second T-shaped plate 13. The lifting component includes a telescopic cylinder 17 fixedly installed on the upper surface of the mounting plate 16. The drive shaft of the telescopic cylinder 17 is fixedly connected to the bottom of the second T-shaped plate 13.

[0023] When the equipment is not in use, and the drive motor 6 and the winch roller 7 have been rotated to a parallel state with the mast 4 by the servo motor 9, the protective mechanism can cover and protect the winch mechanism and the tarpaulin according to the following process. The protective mechanism is started by the telescopic cylinder 17 as the power source. At this time, the operator controls the telescopic cylinder 17 on the mounting plate 16 to start, and its drive shaft extends upward, driving the second T-shaped plate 13 fixedly connected to it to rise in the vertical direction. Since the top ends of the two threaded rods 14 on the upper surface of the second T-shaped plate 13 are respectively threaded in the threaded grooves 15 at the bottom of the two rotating rods 10, and the surface thread directions of the two threaded rods 14 are opposite, when the second T-shaped plate 13 rises, the two threaded rods 14 move upward synchronously, and drive the two rotating rods 10 to rotate relative to each other in the rotation opening of the first T-shaped plate 12 through the threaded engagement. The left rotating rod 10 rotates in the clockwise direction, and the right rotating rod 10 rotates in the counterclockwise direction (or vice versa).

[0024] During the rotation of the two rotating rods 10, the protective plates 11 fixedly sleeved on their surfaces rotate synchronously. Since the rotation angle of the rotating rods 10 is controlled by the rising height of the threaded rod 14, the telescopic cylinder 17 continuously drives the second T-shaped plate 13 to rise until the edges of the two protective plates 11 abut against each other, forming a closed enclosure space. At this time, the drive motor 6, the winch roller 7, and the tarpaulin rolled up on the winch roller 7, which are parallel to the mast 4, are completely wrapped in the space enclosed by the two protective plates 11 and the first T-shaped plate 12.

[0025] When the equipment needs to be used again, simply control the retraction of the drive shaft of the telescopic cylinder 17 to drive the second T-shaped plate 13 and the threaded rod 14 to descend. Through the reverse thread transmission, the two rotating rods 10 drive the protective plate 11 to rotate in the opposite direction until the protective plate 11 is fully opened, thus removing the cover over the winch mechanism without affecting the normal working posture adjustment of the drive motor 6 and the winch roller 7.

[0026] During this protective process, the protective plate 11 can effectively block external dust, rainwater and debris from directly contacting the drive motor 6, the winch roller 7 and the tarpaulin, preventing the internal components of the motor from getting damp and rusting, and preventing the surface of the winch roller 7 from getting dirty and affecting the flatness of the tarpaulin roll. At the same time, it prevents the tarpaulin from aging and becoming brittle due to long-term exposure to sunlight, significantly extending the service life of the winch mechanism and the protective performance of the tarpaulin. In addition, through the cooperation of the threaded assembly and the telescopic cylinder 17, the automatic opening and closing of the protective plate 11 is realized. The operation is convenient and the coverage is tight. The protective operation can be completed when the equipment is idle without additional manual intervention.

[0027] Both protective plates 11 have a sealing layer bonded to their contact surfaces, and the sealing layer is made of rubber.

[0028] The rubber material has good elasticity and extensibility. When the two protective plates 11 come into contact, the sealing layer will undergo slight deformation under the contact pressure, tightly filling the tiny gaps on the contact surface of the protective plates 11. This characteristic can effectively block the intrusion of external dust, water vapor, rainwater and other impurities, preventing them from penetrating into the interior through the gaps and causing corrosion to the drive motor 6, the winch roller 7 and the rolled-up tarpaulin, further strengthening the sealing and protective effect of the protective mechanism.

[0029] In this invention, the wheeled vehicle body 1 facilitates the movement of the equipment between different work locations, improving the equipment's flexibility and applicability. The liftable mast 4 can adjust its height according to actual needs, adapting to different height covering requirements. Combined with the slewing support assembly 2, the covering position of the tarpaulin can be flexibly adjusted to meet the usage needs in different scenarios. The hoisting mechanism can control the release and rewinding of the tarpaulin through the forward and reverse rotation of the hoisting roller 7, reducing manual labor intensity and improving work efficiency. When the tarpaulin is in the rewinding state on the hoisting roller 7, the servo motor 9 can control the drive motor 6 and the hoisting roller 7 to rotate to a state parallel to the mast 4, thereby reducing the overall space occupied by the device and facilitating its movement.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
