Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle washing devices, and specifically relates to a vehicle washing telescopic arm suitable for ultra-long and narrow spaces. Background Technology

[0002] As the livestock industry becomes increasingly prosperous and technological advancements lead to a rise in large-scale intensive farms, the demand for cleaning and disinfecting livestock transport vehicles is also growing. With the gradual automation of disinfection and cleaning equipment, the demand for automated cleaning equipment is becoming increasingly strong.

[0003] CN217753705U discloses a conveying pipeline for a telescopic boom used for cleaning carriages, including a cable chain. The cable chain is disposed on the side end of the telescopic boom, and a cable chain box is disposed on the outer side of the telescopic boom frame. One end of the cable chain is fixedly connected to the front end of the telescopic boom. After the middle of the cable chain is bent once, the other end is fixedly connected to the front end of the telescopic boom frame inside the cable chain box. Since the cable chain is disposed on the side end of the telescopic boom, it is limited by the length of the telescopic boom. The cable chain is 6 meters in a single layer and 12 meters in a double layer. The telescopic boom can extend up to 12 meters, but this cannot meet the cleaning needs of ultra-long carriages (length greater than 12 meters). Moreover, placing the cable chain on the side end of the telescopic boom will increase the overall width of the telescopic boom, which cannot meet the cleaning needs of carriages with narrow spaces. Summary of the Invention

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a vehicle washing telescopic arm suitable for ultra-long and narrow spaces includes a main arm, a multi-stage movable arm, a nozzle, and a cable chain. The multi-stage movable arm is disposed within the main arm and extends and retracts left and right along the length of the main arm. The multi-stage movable arm includes multiple movable arms, which are sequentially disposed within the preceding movable arm from left to right and move left and right within the preceding movable arm. The nozzle is disposed at the right end of the rightmost movable arm. The cable chain is disposed within the multi-stage movable arm and includes an upper cable chain and a lower cable chain. One end of the upper cable chain is connected to the left side of the rightmost movable arm, and the other end is connected to the left side of another movable arm to its left. One end of the lower cable chain is connected to the movable arm at the position where the upper cable chain is connected, and the other end is connected to the interior of the main arm. The nozzle's pipeline passes through the lower cable chain and the upper cable chain sequentially to enter the rightmost movable arm and communicates with the nozzle.

[0005] The main boom includes a fixed frame and a cable chain plate. The cable chain plate is located inside the fixed frame, and the multi-stage movable boom is located inside the fixed frame and extends and retracts left and right along the length of the fixed frame.

[0006] The main arm is equipped with a chain drive device, and the leftmost movable arm moves left and right along the length of the main arm via the chain drive device.

[0007] The chain drive device includes a motor, a reducer, a drive sprocket, a driven sprocket, and a chain. The motor is fixed to the side end of the main arm. The output end of the motor is connected to the reducer. The output end of the reducer is connected to the drive sprocket. One end of the chain passes over the drive sprocket and is driven by the drive sprocket. The other end of the chain passes over the driven sprocket and is connected to the bottom of the leftmost movable arm.

[0008] The movable arm includes a base plate, dual driven sprockets, guide wheels, and traveling wheels. The base plate has a hollow structure with an opening at the top. The dual driven sprockets consist of two coaxially arranged outward-extending sprockets and a retracting sprocket. The dual driven sprockets are provided at both ends of the movable arm. The guide wheels are located at both ends of the base plate. The right side of the movable arm slides along the inner side of the base plate via the guide wheels. There are multiple guide wheels. The traveling wheels are located at the right end of the movable arm. The movable arm is supported by the traveling wheels and moves within the carriage.

[0009] The right end of the movable arm is provided with a first fixing plate and a second fixing plate, which are arranged from left to right. The left end of the movable arm is provided with a third fixing plate and a fourth fixing plate, which are arranged from left to right.

[0010] The right end of the main arm is also provided with a first fixing plate and a second fixing plate, which are arranged from left to right.

[0011] The extension and retraction between the multi-stage movable arms are achieved through telescopic chains, which include an outward extending chain and a retracting chain. The outward extending chain controls the multi-stage movable arms to extend to the right, and the retracting chain controls the multi-stage movable arms to retract to the left. The two ends of the outward extending chain are respectively connected to the fourth fixed plate of the movable arm and the second fixed plate of the upper-level movable arm. The upper-level movable arm is the second movable arm or main arm on the left side of the movable arm. The outward extending chain meshes with the outward extending sprocket on the left side of the movable arm and the outward extending sprocket on the right side of the upper-level movable arm. The upper-level movable arm is the movable arm adjacent to the left side of the movable arm. The two ends of the retracting chain are respectively connected to the first fixed plate of the lower-level movable arm and the third fixed plate of the upper-level movable arm. The lower-level movable arm is the movable arm adjacent to the right side of the movable arm. The retracting chain meshes with the retracting sprocket on the left side of the movable arm and the retracting sprocket on the right side of the upper-level movable arm.

[0012] The nozzle includes a multi-angle cleaning nozzle and a rotating nozzle. The multi-angle cleaning nozzle includes multiple nozzles distributed axially. The rotating nozzle is connected to the rightmost movable arm shaft, and the movable arm is equipped with a rotary motor to control the rotation speed of the rotating nozzle.

[0013] The vehicle washing telescopic boom obtained through the above technical solution, suitable for ultra-long and narrow spaces, has the following advantages: By setting up two cable chains and connecting their upper ends with a movable arm, the overall extension length of the cable chain is achieved through the joint action of the two cable chains when the movable arm extends, which can effectively increase the extension length of the telescopic arm when the cable chain length is limited.

[0014] Placing the cable chain inside the multi-stage telescopic arm can effectively reduce the width of the telescopic arm, making it more suitable for cleaning in narrow spaces. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Unless otherwise defined, the technical terms used in the following embodiments have the same meaning as commonly understood by those skilled in the art to which this utility model pertains.

[0019] The present invention will be further explained below with reference to the embodiments and accompanying drawings. It should be understood that the present invention is not limited to the specific embodiments described.

[0020] like Figure 1 As shown, this utility model proposes a vehicle washing telescopic arm suitable for ultra-long and narrow spaces, including a main arm 1, a multi-stage movable arm 2, a nozzle 3, and a cable chain 4. The multi-stage movable arm 2 is disposed within the main arm 1 and extends and retracts left and right along the length of the main arm 1. The multi-stage movable arm 2 includes multiple movable arms 21, which are sequentially disposed within the preceding movable arm from left to right and move left and right within the preceding movable arm. The nozzle 3 is disposed at the right end of the rightmost movable arm 21, and the cable chain 4 is disposed within the... Within the multi-stage movable arm 2, the cable chain 4 includes an upper cable chain 41 and a lower cable chain 42. One end of the upper cable chain 41 is connected to the left side of the rightmost movable arm 21, and the other end is connected to the left side of another movable arm 21 to its left. One end of the lower cable chain 42 is connected to the movable arm 21 at the position where it is connected to the upper cable chain 41, and the other end is connected to the inside of the main stage arm 1. The pipeline of the nozzle 3 enters the rightmost movable arm 21 and communicates with the nozzle 3 by passing through the lower cable chain 42 and the upper cable chain 41 in sequence.

[0021] In the initial position, the multi-stage movable arm 2 is in a retracted state, and the upper drag chain 41 and lower drag chain 42 are not deployed. When the multi-stage movable arm 2 extends to the right, the telescopic arm connected to the upper drag chain 41 and lower drag chain 42 moves to the right. At this time, the connection between the upper drag chain and the lower drag chain 42 moves to the right at the same time, and the lower drag chain 42 unfolds to the right relative to the main arm 1. The rightmost movable arm 21 moves to the right relative to the movable arm 21 connecting the upper drag chain 41 and the lower drag chain 42, and the upper drag chain 41 is unfolded to the right. Due to the limitation of the drag chain length, the maximum length of the multi-stage movable arm 2 when it is unfolded is the length of the upper drag chain 41 plus the length of the lower drag chain 42.

[0022] like Figure 2 As shown, the main arm 1 includes a fixed frame 11 and a cable chain plate 12. The cable chain plate 12 is disposed inside the fixed frame 11, and the lower end of the lower cable chain 42 is supported by the cable chain plate 12. The multi-stage movable arm 2 is disposed inside the fixed frame 11 and extends and retracts left and right along the length direction of the fixed frame 11.

[0023] like Figure 3As shown, a chain drive device 5 is provided on the main arm 1, and the leftmost movable arm 21 moves left and right along the length direction of the main arm 1 through the chain drive device 5.

[0024] The chain drive device 5 includes a motor 51, a reducer 52, a drive sprocket 53, a driven sprocket 54, and a chain 55. The motor 51 is fixed to the side end of the main arm 1. The output end of the motor 51 is connected to the reducer 52. The output end of the reducer 52 is connected to the drive sprocket 53. One end of the chain 55 passes over the drive sprocket 53 and is driven by the drive sprocket 53. The other end of the chain 55 passes over the driven sprocket 54 and is connected to the bottom of the leftmost movable arm 21.

[0025] The chain drive device 5 is a bidirectional drive. In the initial position, the multi-stage movable arm 2 is not extended. The motor 51 controls the drive sprocket 53 to rotate clockwise through the reducer 52. The chain 55 rotates clockwise accordingly, driving the leftmost movable arm 21 to move to the right. At this time, the movable arm 21 extends to the right. When it is necessary to retract the movable arm 21, the motor 51 controls the drive sprocket 53 to rotate counterclockwise through the reducer 52. The chain 55 rotates counterclockwise accordingly, driving the leftmost movable arm 21 to move to the left. At this time, the movable arm 21 retracts to the left.

[0026] like Figure 4-7 As shown, the movable arm 21 includes a base plate 21a, double driven sprockets 21b, guide wheels 21c, and traveling wheels 21d. The base plate 21a is a hollow structure with an opening at the top. The double driven sprockets 21b consist of two coaxially arranged outward-extending sprockets 21b1 and a retracting sprocket 21b2. The double driven sprockets 21b are provided at both ends of the movable arm 21. The guide wheels 21c are provided at both ends of the base plate 21a. The right side of the movable arm 21 slides along the inner side of the base plate 21a via the guide wheels 21c. There are multiple guide wheels 21c. The traveling wheels 21d are provided at the right end of the movable arm 21. The movable arm 21 is supported by the traveling wheels 21d and moves within the carriage.

[0027] The right end of the movable arm 21 is provided with a first fixing plate 21e and a second fixing plate 21f, which are arranged from left to right. The left end of the movable arm 21 is provided with a third fixing plate 21g and a fourth fixing plate 21h, which are arranged from left to right.

[0028] The right end of the main arm 1 is also provided with a first fixing plate 21e and a second fixing plate 21f, which are arranged from left to right.

[0029] The extension and retraction between the multi-stage movable arms 2 are achieved through a telescopic chain 6, which includes an outward extending chain 61 and a retracting chain 62. The outward extending chain 61 controls the multi-stage movable arm 2 to extend to the right, and the retracting chain 62 controls the multi-stage movable arm 2 to retract to the left. The two ends of the outward extending chain 61 are respectively connected to the fourth fixing plate 21h of the movable arm 21 and the second fixing plate 21f of the upper-level movable arm. The upper-level movable arm is the second movable arm 21 on the left side of the movable arm or the main stage arm 1, and the outward extending chain is respectively connected to the movable arm 21. The extended sprocket 21b1 on the left side of the arm engages with the extended sprocket 21b1 on the right side of the upper movable arm. The upper movable arm is the movable arm 21 adjacent to the left side of the movable arm 21. The two ends of the retractable chain 62 are respectively connected to the first fixing plate 21e of the lower movable arm and the third fixing plate 21g of the upper movable arm. The lower movable arm is the movable arm 21 adjacent to the right side of the movable arm 21. The retractable chain 62 engages with the retractable sprocket 21b2 on the left side of the movable arm and the retractable sprocket 21b2 on the right side of the upper movable arm.

[0030] It should be noted that the leftmost movable arm 21 is only equipped with a retractable chain 52, while the rightmost movable arm 21 is only equipped with an extended chain 51.

[0031] When the multi-stage telescopic arm 1 needs to extend, the chain drive device 5 drives the leftmost movable arm 21 to move to the right. The extension chain 61 of the lower movable arm 21, which meshes with the right extension sprocket 21b1, moves to the right accordingly. Since the left side of the extension chain 61 is connected to the left side of the lower movable arm, the extension chain 61 pulls the lower movable arm to move to the right as a whole. The right extension sprocket 21b1 drives the extension chain 61 of the next lower movable arm to move to the right. And so on, the multi-stage movable arm 21 extends to the right as a whole. At this time, the retracting chain 62 unfolds to the right synchronously according to the coaxial transmission of the double driven sprockets 21b. When the multi-stage telescopic arm 1 needs to retract, the chain drive device drives the leftmost movable arm 21 to move to the left. Its left retraction sprocket 21b2 moves to the left in sync, driving the retraction chain 62 of the lower movable arm 21 that is meshed with it to move to the left in sync, and pulling the lower movable arm connected with it to move to the left. Since the retraction sprocket 21b2 on the left side of the lower movable arm 21 is meshed with the retraction chain 62 of the next lower movable arm, it pulls the next lower movable arm to move to the left. And so on, the multi-stage movable arm 21 retracts to the left as a whole. At this time, the extended chain 61 returns to the left in sync according to the coaxial transmission of the double driven sprockets 21b.

[0032] The nozzle 3 includes a multi-angle cleaning nozzle 31 and a rotating nozzle 32. The multi-angle cleaning nozzle 31 includes multiple nozzles distributed axially. The rotating nozzle 32 is axially connected to the rightmost movable arm 21, and the movable arm is equipped with a rotary motor to control the rotation speed of the rotating nozzle 32, which can effectively control the rotation speed of the nozzle and enhance the cleaning effect.

[0033] Taking a number of four movable arms as an example, the movable arms are arranged from left to right along their extension direction as a first-level movable arm, a second-level movable arm, a third-level movable arm, and a fourth-level movable arm. A drag chain frame is set at the left end of the second-level movable arm to connect the upper drag chain 41 and the lower drag chain 42.

[0034] When cleaning is required in a narrow space, the chain drive device 5 is activated, causing the first-stage movable arm to move to the right. The extended chain pulls the second-stage movable arm, the third-stage movable arm, and the fourth-stage movable arm to move to the right in sequence. The multi-stage movable arm 2 extends. At this time, the upper drag chain 41 set between the second-stage and fourth-stage movable arms is unfolded to the left, and the lower drag chain 42 set between the second-stage movable arm and the main arm is unfolded to the left. Then, cleaning is carried out through the nozzle 3.

[0035] After cleaning, start the chain drive device 5 and move it to the left. The retracting chain pulls the second-stage movable arm, the third-stage movable arm, and the fourth-stage movable arm to the left in sequence. The multi-stage movable arm 2 retracts, and the upper drag chain 41 set between the second-stage and fourth-stage movable arms is retracted to the right. At this time, the lower drag chain 42 set between the second-stage and main-stage movable arms is retracted to the right.
