Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation pipe production technology, specifically relating to a trolley control system for processing thermal insulation pipes. Background Technology

[0002] Insulated pipes, also known as thermal pipelines, are heating pipes that connect a heat source to the building's heating inlet. Multiple heating pipes are interconnected to form a thermal network. Insulated pipes generally employ a double-layered structure, with common structural forms including steel-jacketed steel insulated pipes and plastic-jacketed steel insulated pipes. Insulated pipes mainly consist of a working pipe (layered from the inside out), an insulation layer, and an outer protective pipe. During the production of insulated pipes, the pipe components inevitably need to be transferred and moved. Traditionally, this is done using overhead cranes, which is inefficient and carries a high risk. To improve the efficiency and safety of pipe transfer in the production workshop, the factory has adopted a modification scheme by adding transport trolleys. However, the existing trolley control is still mainly manual remote control, resulting in low automation, requiring dedicated human resources, and posing a risk of human error. Therefore, it is necessary to further upgrade and optimize the existing trolley control method. Utility Model Content

[0003] In view of the above situation, this utility model provides a trolley control system for processing insulated pipes, which can greatly improve the automation level of existing trolley control, reduce manual intervention, and improve the safety factor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A trolley control system for processing insulated pipes includes pipes and pipe supports for temporary storage of pipes, as well as a trolley assembly and a trolley track for guiding the trolley assembly, the trolley track being disposed to the side of the pipe supports.

[0006] The trolley assembly includes an active trolley and a follower trolley, which are arranged one after the other on the trolley track along the extension direction of the trolley track. The follower trolley and the active trolley are connected to each other through an intermediate frame. Both the active trolley and the follower trolley include a car body and rail wheels. Each car body is mounted on the trolley track above it by rail wheels that are installed at the bottom of the car body. The top of the two car bodies is provided with pipe brackets for lifting the head and tail of the pipe, respectively.

[0007] The active trolley is equipped with a main trolley motor inside its body for driving the rotation of its rail wheels, and a main trolley control box for controlling the active trolley. The main trolley motor is electrically connected to the main trolley control box.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0023] It should be noted that the terms "upper," "lower," "front," "back," "left," "right," "inner," and "outer," which indicate directions or positional relationships, are based on the attached drawings and are used only for ease of description.

[0024] Example 1

[0025] like Figure 1-2 As shown, a trolley control system for processing insulated pipes includes a pipe 1 and a pipe support 2 for temporary storage of pipes (which can be regarded as a transfer warehouse for pipes), as well as a trolley group and a trolley track 3 for guiding the movement of the trolley group. The trolley track is located on the side of the pipe support.

[0026] The trolley assembly includes an active trolley 4 and a follower trolley 5, which are arranged one in front of the other on the trolley track along the extension direction of the trolley track. The follower trolley and the active trolley are connected to each other through an intermediate frame. Both the active trolley and the follower trolley include a car body and rail wheels. Each car body is mounted on the trolley track above the trolley track by rail wheels that are installed at the bottom of the car body. The top of the two car bodies is provided with pipe brackets for lifting the head and tail of the pipe, respectively.

[0027] The active trolley is equipped with a main trolley motor (not shown in the figure) for driving its rail wheels to rotate, and a main trolley control box 6 for controlling the active trolley. The main trolley motor is electrically connected to the main trolley control box.

[0028] The intermediate frame adopts a spliced ​​rod structure with adjustable length. The intermediate frame includes a connecting rod 8 fixed at the rear of the active trolley and a connecting rod 9 fixed at the front of the follower trolley. The two connecting rods are connected at their close ends by a connector 10.

[0029] The connecting rod 1, connecting rod 2, and connector are all made of square tubing. The ends of the two connecting rods slide through the inner side of the square tubing of the connector. The connector is sleeved on the outer side of the connecting ends of the two connecting rods. Each connecting end of the two connecting rods has a set of connecting holes. The side wall of the connector has several sets of connecting holes. By using connecting bolts 11 to connect the connecting holes of the two connecting rods and the connecting holes at different positions on the connector, the length of the intermediate frame can be adjusted. The length of the intermediate frame can be adjusted appropriately according to the length of the pipes produced, thereby adjusting the interval between the two vehicles. The length of the square tubing of the connector and the number of its connecting holes are determined according to the implementation requirements.

[0030] Both pipe brackets are self-unloading, tiltable brackets. Each pipe bracket includes two V-shaped brackets 12 tiltably mounted at the front and rear ends of the vehicle body for placing pipes, and a tilting push rod 13 for driving the two V-shaped brackets to tilt. The left ends of the two V-shaped brackets are rotatably connected to the surface of the vehicle body via hinge seats 14. Rubber protective pads 27 are also provided on the V-shaped contact surfaces of the V-shaped brackets and pipes, which can provide a certain degree of protection for the outer protective layer and insulation layer of the pipes. A push shaft 15 is connected between the right ends of the two V-shaped brackets. The pipe brackets are located on the left side of the vehicle body. The tilting push rod is a hydraulic cylinder. The base of the hydraulic cylinder is rotatably hinged to the side of the vehicle body, and the top of the piston rod of the hydraulic cylinder is rotatably connected to the middle of the push shaft via a fisheye bearing 16.

[0031] The servo trolley is equipped with a motor (not shown in the figure) inside its body to drive the rotation of its rail wheels, and a control box 7 for controlling the servo trolley. The motor is electrically connected to the control box. The active trolley is equipped with a wireless signal transmitter 17 electrically connected to the control box, and the servo trolley is equipped with a wireless signal receiver 18 to receive control signals from the transmitter. The control box enables synchronous rotation between the motor and the main motor, thus achieving synchronous start-stop between the active and servo trolleys, as well as synchronous rotation of the two pipe supports. Additionally, a central control room (not shown in the figure) is provided in the production workshop. The central control room can also communicate wirelessly with the active trolley's wireless transmitter via the receiver to monitor the real-time location and operation of the trolley system.

[0032] The active trolley is equipped with a deceleration switch 19 for triggering deceleration and a positioning switch 20 for detecting positioning. Both the deceleration switch and the positioning switch are swing-arm type mechanical limit switches. The deceleration switch is located in front of the positioning switch. A limit stop 21 is set on the workshop floor outside the trolley track. When the active trolley moves close to the limit stop, the deceleration switch touches the limit stop first. Due to inertia, the active trolley will not stop instantly, but will first stop the movement of the track wheels, allowing the trolley to pass the limit stop and gradually decelerate until the limit stop triggers the positioning switch and maintains its position. This indicates that the trolley has stopped at the designated position corresponding to the pipe support, and then the tilting push rod can be activated to unload the pipe.

[0033] A travel alarm 22 is also installed on the side wall of the active trolley. The travel alarm is an audible and visual alarm. When the active trolley and the follower trolley are moving, the travel alarm will emit an audible and visual alarm to alert personnel. The deceleration switch, the position switch, and the travel alarm are all electrically connected to the main vehicle control box. The main vehicle control box and the follower control box and their internal control circuit settings are all existing technologies and will not be described in detail here.

[0034] Both the active and follower trolleys are equipped with internal battery packs (not shown in the figure) to provide power for their operation. It is important to charge the battery packs regularly, and it is also advisable to have two spare battery packs on hand for easy battery replacement, preventing production delays caused by dead or insufficient battery power.

[0035] Example 2

[0036] Based on Example 1, the main difference between Example 2 and Example 1 is that the power supply method for the active trolley and the follower trolley is different. In this example, two trolley tracks are laid in parallel on the workshop floor to the right of the pipe support. The bodies of the active trolley and the follower trolley are each set above the two trolley tracks by two sets of rail wheels.

[0037] like Figure 2 As shown, a power trench 23 is provided beneath the workshop floor between the two trolley tracks. Conductive tracks 24 are laid on the inner sidewalls of the power trench. The active trolley and the follower trolley each cooperate to draw power from the conductive tracks via a brush device, which better avoids the problem of battery depletion or insufficient power that may occur when using a battery pack for power supply. The brush device includes brushes 25 and brush holders 26. Both the brushes and brush holders adopt existing technology, and their specific structures will not be described in detail here.

[0038] The technical solution of this utility model is not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of this utility model shall fall within the protection scope of this utility model.
