Description

Technical Field

[0001] The utility model relates to a segmented transfer frame, in particular to a gantry type segmented transfer frame. Background Art

[0002] Block manufacturing, pre-outfitting, block painting, and assembly are essential links in shipbuilding, but between each link, there is a process of block transfer and shelving, and block transfer and block shelving have become an important process. Because when transferring and shelving blocks, their safety and convenience must be fully considered.

[0003] To transfer the sections, 6 to 8 sleepers must be arranged on the transport hydraulic flatbed truck first, and then the sections must be lifted onto the transport flatbed truck by a crane and fixed. After the sections are transported to the designated placement location, 4 to 6 steel piers and sleepers must be placed on the ground on both sides of the flatbed truck, and then the hydraulic flatbed truck must be lowered to the appropriate position to place the sections on the pre-placed steel piers and sleepers. After the sections are placed securely, the flatbed truck must be withdrawn. This process requires the joint cooperation of at least 4 to 8 people to be completed effectively, but there are considerable safety risks. Moreover, the time for transferring and shelving the sections is relatively long. Under normal circumstances, the maximum number of sections that can be transferred and shelved in half a day is about 2, and the flatbed truck is a very expensive piece of equipment, and low utilization will increase the cost of shipbuilding.

[0004] Therefore, it is necessary to design a gantry-type segmented transfer frame to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the long time of transferring and laying aside the sections, under normal circumstances, the maximum number of sections that can be transferred and laid up in half a day is about 2. However, flatbed trucks are very expensive equipment, and their low utilization rate will increase the cost of shipbuilding. The technical problem to be solved is: to provide a gantry-type section transfer rack.

[0006] The technical solution of the utility model is: a gantry-type segmented transfer frame, including a door frame, a controller, moving wheels, sliders and sleepers. There are two door frames, which are symmetrically distributed on the ground front and back. The right part of the door frame located on the front side is fixedly connected with the controller, and the moving wheels are symmetrically rotatably connected on both sides of the lower part of each door frame. The sliders are fixedly connected on both sides of the upper part of each door frame, and sleepers are fixedly connected between the sliders on one side of the two door frames.

[0007] In one of the embodiments, it also includes a motor, a first sprocket, a second sprocket, a chain and a sliding wheel. Each of the sliders is symmetrically fixedly connected to the motor, the first sprocket is fixedly connected to the output shaft of each motor, a sliding groove is symmetrically opened on the upper part of each door frame, and two sliding wheels are symmetrically rollingly connected in the sliding groove of each door frame. The two sliding wheels on one side of each door frame are rotatably connected to the corresponding slider, the second sprocket is fixedly connected to one end of each sliding wheel, the chain is wound around each of the first sprocket and the corresponding two second sprockets, and each motor is electrically connected to the controller.

[0008] In one of the embodiments, the two sliding wheels on one side of each door frame are symmetrically distributed on both sides of the corresponding sliding block.

[0009] In one of the embodiments, it also includes a fixed seat, a guide plate, a torsion spring, a first trigger block, a second trigger block and a warning light. The fixed seat is symmetrically fixedly connected to the middle of each door frame, and the two fixed seats on each door frame are rotatably connected to the guide plate on one side. A number of torsion springs are connected between each fixed seat and the corresponding guide plate. The rear of each guide plate is fixedly connected to the first trigger block, and the rear of each fixed seat is fixedly connected to the second trigger block. The first trigger block is in contact with the second trigger block, and the front of each fixed seat is fixedly connected to the warning light. Each first trigger block, each second trigger block and each warning light are electrically connected to the controller.

[0010] In one of the embodiments, it further includes a bracket and a roller, wherein the front portion of each guide plate is fixedly connected to the bracket, and a plurality of rollers are rotatably connected to a linear array on each bracket.

[0011] In one of the embodiments, a protective cover is further included, and each of the sliders is symmetrically fixedly connected to the protective cover for preventing debris from getting stuck in the first sprocket, the second sprocket and the chain.

[0012] 1. The utility model improves the production efficiency by more than double compared with the conventional method by using the gantry-type segmented transfer frame to transfer the segments, and also reduces the number of operators and the labor intensity of the workers.

[0013] 2. The utility model drives the first sprocket to rotate through a motor, and then drives the second sprocket to rotate through a chain. The rotation of the second sprocket causes the sliding wheel to roll, and the rolling of the sliding wheel causes the slider to move along the track. The movement of the slider drives the sleepers to move to a suitable position. When the sections are placed, the sleepers can be accurately moved into place, ensuring that the contact between the sections and the sleepers is more stable, thereby achieving more effective support.

[0014] 3. Before the flatbed truck enters the door frame, the utility model will squeeze the guide plate. The rotation of the guide plate will cause the first trigger block to contact the second trigger block. This contact will trigger the warning light to flash, reminding the staff to pay attention to the entry angle of the flatbed truck. The staff can adjust the angle by observing the warning light before the flatbed truck enters the door frame, thereby effectively preventing the flatbed truck from colliding with the door frame, reducing the company's production costs and improving safety.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] Embodiment: Gantry type segmented transfer rack, such as Figure 1-Figure 4As shown, it includes a door frame 1, a controller 101, a moving wheel 2, a slider 3, a sleeper 9, a motor 4, a first sprocket 5, a second sprocket 6, a chain 7 and a sliding wheel 8. There are two door frames 1, which are symmetrically distributed on the ground front and back. The right side of the door frame 1 located on the front side is installed with a controller 101 by screws, and the moving wheels 2 are symmetrically connected to the left and right sides of the lower part of each door frame 1. The sliders 3 are welded to the left and right sides of the upper part of each door frame 1. The sleepers 9 are fixed between the sliders 3 on the same side of the two door frames 1 by screws. Each slider 3 is symmetrically installed with the motor 4 by screws. The first sprocket 5 is welded on the output shaft, and each of the door frames 1 has a sliding groove symmetrically opened on the front and back upper part. Two sliding wheels 8 are symmetrically connected to the sliding groove of each door frame 1 for rolling. The two sliding wheels 8 on the same side of each door frame 1 are rotatably connected to the corresponding slider 3, and the two sliding wheels 8 on the same side of each door frame 1 are symmetrically distributed on both sides of the corresponding slider 3. The second sprocket 6 is welded on the end of each sliding wheel 8 away from the corresponding door frame 1, and the chain 7 is wound around each first sprocket 5 and the corresponding two second sprockets 6, and each motor 4 is electrically connected to the controller 101.

[0023] Considering that the weight of a segment generally does not exceed 75 tons, the load-bearing capacity of the gantry 1 is set to 50 tons. Therefore, a pair of gantries 1 (i.e., two gantries 1) can bear the weight of one segment. Before the segment is transported, the segment can be hoisted in the workshop onto the already placed gantry 1, and then the flatbed truck is driven under the gantry 1, and the hydraulic system is started to raise the loading flatbed of the flatbed truck. The loading flatbed props up the segment and the gantry 1 together, and then the flatbed truck moves the segment and the gantry 1 to the designated area. After arriving at the destination, the hydraulic system is started again to lower the segment and the gantry 1, thereby realizing the transportation of the segment. Before transportation, the segment is hoisted and placed on the gantry 1. At this time, the motor 4 can be started by the controller 101 to adjust To adjust the position of the sleeper 9, the output shaft of the motor 4 drives the first sprocket 5 to rotate clockwise, and the second sprocket 6 is also rotated clockwise through the chain 7, which drives the sliding wheel 8 to rotate clockwise. The rotation of the sliding wheel 8 makes the slider 3 move to the right, and then drives the sleeper 9 to move to the right to a suitable position. Conversely, when the output shaft of the motor 4 drives the first sprocket 5 to rotate counterclockwise, the sliding wheel 8 rotates counterclockwise through the same chain 7 transmission mechanism, and the slider 3 moves to the left, which drives the sleeper 9 to move to the left to a suitable position. The staff can adjust the position of the sleeper 9 by controlling the motor 4, thereby ensuring that the sleeper 9 can be moved to a suitable position when the sections are placed, so that the contact support between the sections and the sleepers 9 is more stable.

[0024] like Figure 1 , Figure 4 and Figure 5As shown, it also includes a fixing seat 10, a guide plate 11, a torsion spring 12, a first trigger block 13, a second trigger block 14, a warning light 15, a bracket 16, a roller 17 and a protective cover 18. The fixing seat 10 is symmetrically installed on the left and right sides of each door frame 1 by screws, and the two fixing seats 10 on each door frame 1 are rotatably connected to the guide plate 11 on one side close to each other. The torsion spring 12 is connected to the upper and lower distribution between each fixing seat 10 and the corresponding guide plate 11, and the first trigger block 13 is installed on the rear side of each guide plate 11 by screws. The rear of each fixing seat 10 is screwed The second trigger block 14 is installed, the first trigger block 13 is in contact with the second trigger block 14, the warning light 15 is installed on the front side of each of the fixing seats 10 by screws, each of the first trigger block 13, each of the second trigger block 14 and each of the warning lights 15 are electrically connected to the controller 101, the bracket 16 is installed on the front side of each of the guide plates 11 by screws, and the three rollers 17 are rotatably connected to the linear array on each of the brackets 16, and each of the sliders 3 is symmetrically installed with the protective cover 18 for preventing debris from getting stuck in the first sprocket 5, the second sprocket 6 and the chain 7 by screws.

[0025] When the flatbed truck drives under the gantry 1, in order to avoid the flatbed truck from hitting the gantry 1 due to the angle deflection when entering, an automatic warning system is designed. When the flatbed truck enters the gantry 1, its loading platform first contacts the roller 17, which will squeeze the left guide plate 11 to make it rotate counterclockwise, and the right guide plate 11 will rotate clockwise at the same time. While the guide plate 11 rotates, the torsion spring 12 on it will deform, and the loading platform of the flatbed truck is parallel to the gantry 1. When the first trigger block 13 contacts the second trigger block 14, this contact will be detected by the controller 101, and then the warning light 15 will start flashing. At this time, the staff can drive the flatbed truck in a straight line to the bottom of the gantry 1. When the flatbed truck completely drives out of the gantry 1, the guide plate 11 will automatically reset and rotate to its original position through the action of the torsion spring 12. When the first trigger block 13 is out of contact with the second trigger block 14, the controller 101 will detect this state change and control the warning light 15 to stop flashing. The staff can adjust the entry angle by observing the state of the warning light 15 to ensure that the angle before the flatbed truck drives into the gantry 1 is correct each time.
