Description

Technical Field

[0001] The invention relates to the technical field of fire hoses, in particular to a fire hose production line. Background Art

[0002] The fire hose includes an inner belt and an outer belt. The inner belt is generally a rubber tube, and the outer belt is a braided tube. The inner belt and the outer belt are processed separately, and then the inner belt is inserted into the outer belt to form a double-layer tube. Finally, the completed hose is vulcanized, bonded, wound, installed with a pipe head, and packaged. The traditional method of inserting the hose is inefficient. For this reason, the invention patent with the authorization announcement number CN101598250B provides a method for inserting a fire hose, and the invention patent with the authorization announcement number CN102434731B provides a processing equipment for inserting a fire hose. Only one production line and two operators are needed to complete the inserting of the inner and outer layers of the hose. The inner layer conveying and the outer layer inserting are completed successively by the same crane, which reduces the labor intensity of the operator, and multiple hoses can be processed at the same time, with high production efficiency.

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: 1. When the crane pulls the outer belt or the inner belt to move, the workers are in a waiting state and fail to make full use of manpower; 2. In the patented technology, the connection and disconnection of the inner belt and the clamping device, and the connection and disconnection of the outer belt and the threading device need to be completed manually. When threading multiple water hoses at the same time, workers need to complete the connection of multiple inner belts and the clamping device, the disconnection of the inner belt and the clamping device, the fixation of the inner belt and the iron buckle, and the connection of the outer belt and the threading device in a short time. When the crane pulls the inner belt from the beginning to the end of the production line; or when the crane pulls the outer belt from the end to the beginning of the production line, both workers are in a waiting state. The workers are sometimes busy and sometimes idle, which leads to a tight work rhythm. In addition, there is a lot of room for improvement in the production efficiency of the production line.

[0046] Under normal conditions, the length of a standard fire hose is generally 20 meters. In addition, the length of the fire hose varies according to different usage scenarios and needs: the standard length of the fire hose in the fire hydrant is 25 meters; the length of the fire hose equipped in the engine room and steering gear room does not exceed 15 meters; the length of the hose equipped in the living area, material room and other places does not exceed 20 meters; the length of the hose equipped on the main deck of a ship with a width of more than 30 meters does not exceed 25 meters. In actual production, different lengths of conveyor belts 1 and 2 are customized according to the length of the fire hose. Conveyor belt 1 is responsible for completing the laying of the inner belt 3, and conveyor belt 2 is responsible for completing the insertion of the inner belt 3 and the outer belt 4. The length of conveyor belt 1 and conveyor belt 2, on the basis of meeting the needs of laying the hose, reserves about 1 meter of spare space.

[0047] Two workers are arranged at the sleeve-threading station of the inner belt 3 and the outer belt 4, and worker A and worker B are arranged at the starting end and the end end of the conveyor belt 1 respectively.

[0048] Working steps: a. Worker A holds the clamping device 18 and operates the clamp 183 to clamp one end of the plurality of inner belts 3 on the clamping device 18, and then installs the clamping device 18 in the positioning groove on the positioning plate 135, and the clamping device 18 moves to the end of the conveyor belt 1 with the chain 133; b. When the clamping device 18 passes under the unloading plate 16, the clamp 183 is pressed down and opened by the unloading plate 16, and the inner belt 3 is separated from the clamp 183 and falls onto the support plate 19 under its own gravity and the adsorption force with the support plate 19; c. The clamping device 18 continues to move with the chain 133, and returns from the bottom of the support plate 19 to the bottom of the starting end of the conveyor belt 1. When the clamping device 18 passes through the unloading template 17, it is lifted up by the unloading template 17, and the clamping device 18 is separated from the positioning plate 135; d. Workers A and B cooperate to transfer the inner belt 3 laid on the conveyor belt 1 to the conveyor belt 2 2 and pull Straight, worker B fixes one end of the inner belt 3 on the clamp 211, wraps one end of the outer belt 4 around the clamp 211 and clamps it on the threading device 28, the threading device 28 only clamps the upper layer of the outer belt 4, and then installs the threading device 28 into the positioning groove on the transmission mechanism 23, the threading device 28 moves to the end of the conveyor belt 22 with the transmission mechanism 23, when the threading device 28 passes under the unloading plate 26, the unloading plate 26 opens the clamp on the threading device 28, the outer belt 4 is separated from the threading device 28, and the inner belt 3 is completely inserted into the outer belt 4, and workers A and B jointly move the water hose that has been inserted away from the conveyor belt 22, and the workers at the subsequent workstations will vulcanize, wind, install the pipe head, and package the water hose; e, the threading device 28 continues to move with the transmission mechanism 23, and when it passes through the unloading template 27, the unloading template 27 lifts the threading device 28 and separates it from the transmission mechanism 23.

[0049] When using the fire hose production line, the unloading plate 16 can automatically separate the inner belt 3 from the clamping device 18, the unloading plate 17 can automatically separate the clamping device 18 from the transmission mechanism 13, the unloading plate 26 can automatically separate the outer belt 4 from the threading device 28, and the unloading plate 27 can automatically separate the threading device 28 from the transmission mechanism 23, thereby reducing the workload of workers.

[0050] Worker A can complete the connection between the next set of inner belts 3 and the clamping device 18 and install the clamping device 18 on the transmission mechanism 13 while the inner belt 3 moves from the beginning to the end of the conveyor belt 1. Worker B can complete the connection between the next set of inner belts 3 and the clamping device 211 and the connection between the outer belt 4 and the threading device 28 while the outer belt 4 moves from the beginning to the end of the conveyor belt 2, making full use of the time for waiting for the outer belt 4 and the inner belt 3 to be pulled, and relieving the workers' tense work rhythm.

[0051] The conveyor belt 1 and the conveyor belt 2 rotate continuously without turning, the outer belt 4 and the inner belt 3 can be pulled simultaneously, and multiple groups of outer belts 4 and inner belts 3 can be pulled continuously; due to the use of double chains 133, the distance between the two chains 133 can be freely set, and a larger number of water hoses can be put on at one time, thereby improving production efficiency.

[0052] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
