Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicle technology, and in particular to a tooling for assembling a grabbing and lifting positioner and a blower cylinder. Background Technology

[0002] Dust suppression vehicles, also known as fog cannon trucks, multi-functional spray dust suppression trucks, or long-range fog cannon trucks, are special vehicles that use a high-pressure system to atomize water or dust suppressants and spray them into the air to absorb dust particles and suppress dust pollution. Their core functions include dust removal, haze reduction, and disinfection, and they are widely used in railways, construction sites, and urban roads.

[0003] The fog cannon device on dust suppression trucks, commonly known as a "wind cannon," atomizes water into micron-sized particles (typically 50-150 microns) under high pressure, spraying them into the air to adsorb dust and cause it to settle. Some devices can also adjust the spray distance (up to 100 meters) and coverage angle (such as 180° rotation), and also have functions such as cooling and ozone pollution prevention.

[0004] The pitch angle adjustment of the pneumatic cannon is mainly achieved by the extension and retraction of the hydraulic cylinder. However, at present, when assembling the hydraulic cylinder of the pneumatic cannon, it is necessary to manually pry the hydraulic cylinder to achieve the alignment. Due to the heavy weight of the hydraulic cylinder, there is a safety risk of it sliding backward and hitting and injuring the personnel's hands when prying it. Moreover, the labor intensity is high and the assembly efficiency is low. Utility Model Content

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0046] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] refer to Figures 1 to 3 This utility model discloses a gripping and lifting positioning machine 100, which includes a moving mechanism 110, a lateral moving mechanism 120, a rotating mechanism 130 and a gripper 140.

[0049] The moving mechanism 110 mainly serves to carry and drive the transverse moving mechanism 120, the rotary mechanism 130 and the chuck 140 to rise and fall together. It can also move on the ground to transport the hydraulic cylinders, such as the pneumatic cannon cylinders 310, to various work positions.

[0050] The moving mechanism 110 can be an electric lifting forklift, allowing for direct modification of existing electric lifting forklifts to meet the assembly requirements of lifting, rotating, tilting, and moving in three directions without redesigning the structure of the moving mechanism 110, thus reducing costs. For example, the electric lifting forklift uses a 12V / 150AH battery to drive the hydraulic power unit, achieving lifting function through hydraulic drive. The lifting stroke can reach 1000mm, and it has a self-locking function to achieve suspension and locking at any position within the stroke. Moreover, it can be charged, eliminating the need for cables to provide power, and can be quickly controlled via tabletop buttons, mechanical joysticks, and a wireless remote control.

[0051] For example, the electric lifting forklift mainly includes a chassis 111, a column 112, and an operating platform 113. The chassis 111 is equipped with traveling wheels 114, which can be swivel wheels. The column 112 and the operating platform 113 are both mounted on the chassis 111. The operating platform 113 is located at the rear of the column 112, while the lateral movement mechanism 120, the slewing mechanism 130, and the chuck 140 are located at the front of the column 112. The lateral movement mechanism 120 is slidably mounted on the column 112 so as to drive the slewing mechanism 130 and the chuck 140 to lift and lower. The operating platform 113 is used to control the chuck 140 to realize various position and posture adjustments of the hydraulic cylinder.

[0052] Of course, in some embodiments, the moving mechanism 110 can also be a specially designed mobile trolley with lifting function, as long as it can move on the ground and drive the lateral moving mechanism 120 to lift.

[0053] The lateral movement mechanism 120 is disposed on the moving mechanism 110 and can be raised and lowered under the drive of the moving mechanism 110, thereby driving the rotary mechanism 130 and the chuck 140 to be raised and lowered, and then driving the air cannon cylinder 310 to move laterally.

[0054] The slewing mechanism 130 is disposed on the transverse mechanism 120 and can move horizontally under the drive of the transverse mechanism 120, so as to drive the chuck 140 and the air gun cylinder 310 to move horizontally.

[0055] The chuck 140 is disposed on the rotary mechanism 130. The chuck 140 is used to clamp the hydraulic cylinder 310 of the air gun and can rotate under the drive of the transverse mechanism 120. The rotation plane of the chuck 140 is parallel to the vertical plane, that is, the rotation axis is horizontal, so as to realize the angle displacement of the cylinder's inclined posture. At the same time, the chuck 140 can also make the clamped air gun cylinder 310 rotate to align the air gun cylinder 310 with the opening of the cylinder seat 320 of the air gun 300.

[0056] As described above, in this embodiment, the moving mechanism 110 can carry the pneumatic wrench cylinder 310, which is held by the chuck 140, to the work position where it needs to be assembled, and raise the pneumatic wrench cylinder 310 to a height approximately the same as the assembly position. The lateral movement mechanism 120 can drive the pneumatic wrench cylinder 310 to the assembly position in the horizontal direction. The rotation mechanism 130 can realize the angle displacement adjustment of the oblique viewing posture of the pneumatic wrench cylinder 310. The chuck 140 drives the pneumatic wrench cylinder 310 to rotate, so that the mounting flat ring 311 of the pneumatic wrench cylinder 310 is aligned with the opening of the cylinder seat 320 of the pneumatic wrench 300. Then, the assembly of the pneumatic wrench cylinder 310 can be achieved by connecting the pneumatic wrench cylinder 310 and the pneumatic wrench 300 with a hinge pin. Compared with the prior art, the safety risk and labor intensity are lower, and the assembly operation is simpler, more efficient and efficient.

[0057] In this embodiment, the lateral movement mechanism 120 includes a lifting seat 121, a lateral movement drive component, and a guide rod 123;

[0058] The lifting seat 121 is connected to the moving mechanism 110 and can be lifted and lowered under the drive of the moving mechanism 110, thereby carrying the rotating mechanism 130 and the claw 140 to lift and lower.

[0059] The guide rod 123 is fixed horizontally to the lifting seat 121. The rotary mechanism 130 is slidably engaged with the guide rod 123. For example, the guide rod 123 passes through the rotary mechanism 130, and the rotary mechanism 130 can slide relative to the guide rod 123. Thus, the guide rod 123 guides the rotary mechanism 130 to make precise horizontal lateral movement, while reducing friction.

[0060] The lateral drive component is disposed on the lifting seat 121 and connected to the rotary mechanism 130. It is used to drive the rotary mechanism 130 to move laterally relative to the lifting seat 121, thereby achieving the effect of the rotary mechanism 130 carrying the claw 140 to move laterally.

[0061] In detail, the lateral movement drive includes a lateral movement speed-regulating motor 122 and a lateral movement lead screw assembly. The lateral movement speed-regulating motor 122 is mounted on the lifting seat 121 and connected to the rotary mechanism 130 via the lateral movement lead screw assembly. Thus, the lateral movement speed-regulating motor 122 provides torque, which is converted into linear driving force by the lateral movement lead screw assembly to drive the rotary mechanism 130 to move laterally. Moreover, the lateral movement speed-regulating motor 122 has a self-locking function, which allows the rotary mechanism 130 to stop at any position within the lateral movement stroke range.

[0062] The lateral travel range can be ±150mm. Lateral travel switches can be installed at both extreme positions to detect the position of the rotary mechanism 130. When either lateral travel switch detects the detection device on the rotary mechanism 130, the lateral speed-regulating motor 122 stops, achieving travel protection and preventing excessive lateral displacement. The lateral travel switch can be a photoelectric sensor, a Hall sensor, or other proximity switch; only a corresponding detection device, such as a light-shielding part or a magnet, needs to be installed on the rotary mechanism 130. Alternatively, lateral travel switches can be omitted, and the number of rotations and angle parameters of the lateral speed-regulating motor 122 can be directly positioned and controlled via an encoder.

[0063] The rotary mechanism 130 includes a movable seat 131, a rotary bearing 132, and a rotary drive component;

[0064] The movable seat 131 is connected to the lifting seat 121 of the transverse mechanism 120, and can move horizontally under the drive of the transverse mechanism 120, thereby carrying the claw 140 to move horizontally.

[0065] The slewing bearing 132 is mounted on the movable seat 131, and the pawl 140 is connected to the slewing bearing 132. Specifically, the fixed ring (usually the outer ring) of the slewing bearing 132 is fixedly mounted on the movable seat 131, and the pawl 140 is fixed into the mounting hole of the movable ring (usually the outer ring) of the slewing bearing 132. In this way, the slewing bearing 132 supports the pawl 140, thereby improving the rotational accuracy of the pawl 140 and reducing rotational friction.

[0066] The rotary drive is located on the movable seat 131 and connected to the chuck 140. It is used to drive the chuck 140 to rotate relative to the movable seat 131, thereby achieving the effect of the rotary mechanism 130 carrying the chuck 140 to rotate, thus realizing the displacement of the oblique posture of the air gun cylinder 310.

[0067] In detail, the rotary drive includes a rotary speed-regulating motor 133 and a worm gear assembly. The rotary speed-regulating motor 133 is fixed to the movable seat 131 and connected to the pawl 140 through the worm gear assembly. Thus, the rotary speed-regulating motor 133 provides torque, and the worm gear assembly changes the direction of the torque of the rotary speed-regulating motor 133 and amplifies it to drive the pawl 140 to rotate. Moreover, the rotary speed-regulating motor 133 has a self-locking function, which allows the pawl 140 to stop at any angle within the rotation stroke range, so that the blower cylinder 310 can be suspended in an oblique posture at any angle.

[0068] The rotational stroke range can be ±36°. Rotational limit positions can be individually set with rotary limit switches to detect the rotation angle of the gripper 140. When any rotary limit switch detects the detection and identification device set on the gripper 140, the rotary speed-regulating motor 133 stops, achieving stroke protection and preventing excessive rotation. The rotary limit switch can be a photoelectric sensor, Hall sensor, or other proximity switch; only a corresponding detection and identification device needs to be set on the gripper 140, such as a light-blocking part or a magnet. Alternatively, rotary limit switches can be omitted, and the rotation number, angle, and other parameters of the rotary speed-regulating motor 133 can be directly positioned and controlled by an encoder.

[0069] The chuck 140 includes a support arm 141, a movable jaw 143, and a clamping drive 144. The support arm 141 is connected to the slewing bearing 132 of the slewing mechanism 130 and can rotate under the drive of the traversing mechanism 120. The portion of the support arm 141 away from the slewing mechanism 130 forms a stationary jaw 142. The movable jaw 143 is rotatably connected to the support arm 141 and, together with the stationary jaw 142, is used to clamp the air gun cylinder 310. The clamping drive 144 is connected between the support arm 141 and the movable jaw 143 and is used to drive the movable jaw 143 to move closer to or away from the stationary jaw 142, thereby clamping or releasing the air gun cylinder 310.

[0070] The clamping drive 144 includes an electric push rod, a hydraulic cylinder or a pneumatic cylinder. The two ends of the clamping drive 144 are respectively hinged to the moving jaw 143 and the support arm 141. Thus, by extending or shortening the clamping drive 144, the moving jaw 143 is driven to rotate relative to the support arm 141 to clamp or release the pneumatic hammer cylinder 310.

[0071] The jaw 140 is used to hold the hydraulic cylinder 310 of the pneumatic wrench. Multiple rollers 150 are mounted on the side. At least one roller 150 is connected to the rotation drive 160 mounted on the jaw 140. Specifically, rollers 150 are mounted on the side walls of the moving jaw 143 and the stationary jaw 142 that are close to each other. The rotation drive 160 is mounted on the moving jaw 143. One roller 150 on the moving jaw 143 is connected to the rotation drive 160. In this way, the rotation drive 160 can drive at least one roller 150 to rotate. The friction between the roller 150 and the hydraulic cylinder 310 of the pneumatic wrench causes the hydraulic cylinder 310, which is held by the moving jaw 143 and the stationary jaw 142, to rotate.

[0072] In detail, the self-rotation drive component 160 includes a self-rotation speed-regulating motor 161 and a belt drive assembly 162. The self-rotation speed-regulating motor 161 is fixed to the chuck 140 and connected to the roller 150 through the belt drive assembly 162. Thus, the self-rotation speed-regulating motor 161 provides torque, which is amplified by the belt drive assembly 162 and then supplied to the roller 150 to drive the roller 150 to rotate. The roller 150 then achieves the self-rotation of the air-blasting cylinder 310 through friction with it. Furthermore, the self-rotation speed-regulating motor 161 has a self-locking function, allowing the air-blasting cylinder 310 to stop at any angle within its rotation stroke range to match the opening position of the air-blasting cylinder 310 seat. This ensures that after the air-blasting cylinder 310 rotates, the mounting flat ring 311 aligns with the opening of the air-blasting cylinder 310 seat, facilitating subsequent assembly of the air-blasting cylinder 310 using a hinge pin inserted into the hole.

[0073] The rotation travel range can be ±30°. The rotation limit positions can be achieved by setting rotation limit switches on the upper and lower parts of the conveyor belt corresponding to the belt drive assembly 162 on the support arm 141. These switches detect the identification devices on the conveyor belt. When any rotation limit switch detects the identification device, the rotation speed control motor 161 stops, thus achieving travel protection. The rotation limit switch can be a photoelectric sensor, a Hall sensor, or other proximity switch; only corresponding identification devices, such as light-blocking parts or magnets, need to be set on the conveyor belt. Alternatively, rotation limit switches can be omitted, and the rotation number, angle, and other parameters of the rotation speed control motor 161 can be directly positioned and controlled by an encoder.

[0074] In addition, refer to Figure 1 and Figure 4 This utility model embodiment also discloses an assembly fixture for the hydraulic cylinder 310 of the air gun, which includes a support lifting frame 200 and the gripping, lifting, and positioning machine 100 in the above embodiment. The support lifting frame 200 is mainly used to be placed below the air gun 300 to support the air gun 300 and keep it suspended, so as to facilitate the subsequent use of the gripping, lifting, and positioning machine 100 to transport the hydraulic cylinder 310 of the air gun 300 to the cylinder seat 320 of the air gun 300 for assembly.

[0075] The support lifting frame 200 includes a support frame 210, a support plate 220, a guide column 230, and a lifting drive 240. The guide column 230 is vertically fixed on the support frame 210. The support plate 220 slides with the guide column 230 to precisely guide the support plate 220 to move vertically. The lifting drive 240 is used to lift the support plate 220 relative to the support frame 210. The support plate 220 is used to support the air blower 300. The height of the support plate 220 is adjusted by the lifting drive 240 so that the support plate 220 can be placed under the air blower 300.

[0076] In detail, the support plate 220 can be a V-shaped support plate 220 to better fit the curved outer wall of the pneumatic wrench 300. The support frame 210 is equipped with multiple swivel casters 211 to facilitate workers to push the entire support lifting frame 200 to the bottom of the pneumatic wrench 300. In addition, the mounting frame also has multiple foot supports 212 to provide load-bearing function. The lifting drive 240 includes a handwheel 241 and a lifting screw mechanism, which includes a handwheel 241, a transmission assembly 250, and a lifting screw assembly 242. The screw of the lifting screw assembly 242 is rotatably mounted on the support frame 210 in a vertical position, and the nut is connected to the support plate 220. The transmission assembly 250 can be a worm gear assembly or a gear assembly. The handwheel 241 is connected to the transmission assembly 250, so the transmission assembly 250 reduces the speed of the handwheel 241 and increases the torque. The handwheel 241 is located to the side of the screw assembly, so the transmission assembly 250 also plays a role in changing the direction of torque.

[0077] In summary, this utility model embodiment discloses an assembly fixture for a gripping, lifting, and positioning machine 100 and a pneumatic wrench cylinder 310. It can grip, lift, and increase the horizontal rotation and lateral movement of the pneumatic wrench cylinder 310, as well as the rotation of the inner roller 150 of the chuck 140. Ultimately, it can be controlled by a remote control to quickly and efficiently adjust the cylinder's position in any orientation, including up / down, left / right, rotation, and self-rotation, to meet the requirements of the correct assembly operation.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
