Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and more specifically, to a line-laying device for engineering construction. Background Art

[0002] In the current technological context, the design and application of construction layout equipment face several key challenges and limitations. First, while traditional handheld layout tools provide a certain degree of flexibility in a changing construction environment, they also come with obvious shortcomings. Prolonged handheld operations not only easily lead to operator fatigue and reduce work efficiency, but may also introduce measurement errors due to hand vibration or unstable force control, affecting construction quality.

[0003] To solve these problems, some improved equipment has tried to integrate the pay-off wheel into the mobile vehicle body, aiming to reduce the manpower burden through mechanized movement and improve the accuracy and efficiency of the pay-off operation. However, this type of equipment often lacks the necessary flexibility and adaptability in design. In most cases, the connection structure between the pay-off wheel and the vehicle body is fixed, and does not support or makes it difficult to achieve rapid loading and unloading of the pay-off wheel. This limits the free switching of the equipment between different operating modes, and thus appears to be limited in practical applications.

[0004] In addition, a common problem in the design of handheld pay-off tools is the connection method between the grip and the pay-off reel. Long-term use not only easily leads to damage to the grip, but also considering the differences in operator hand sizes, the fixed grip design often cannot meet the comfortable grip needs of all users. Since the grip and the pay-off reel in traditional designs are mostly connected by welding or other fixed methods, this greatly reduces the flexibility of the equipment in switching between different pay-off modes, and also reduces the replaceability or adjustability of the grip, further affecting the applicability of the tool and user experience.

[0041] More specifically, when handheld line pay-off is needed, first remove the line pay-off reel 1 from the vehicle body 4 according to the above process, then take out the appropriate grip 16, and then dock the corresponding end of the grip 16 with the clamping rod 26 set on one side of the line pay-off reel 1, so that the clamping rod 26 is inserted into the inside of the grip 16. In this process, the clamping block 24 will be squeezed into the inner side of the clamping block 24, and at the same time, the clamping block 24 will cause the second spring 25 connected at one end to be compressed. When the position of the clamping block 24 corresponds to the position of the clamping groove 27, the second spring 25 will automatically reset, thereby pushing the clamping block 24 into the clamping groove 27, so that the clamping block 24 and the clamping groove 27 are engaged with each other, thereby making the handle 16 firmly installed on one side of the line pay-off reel 1, and then the work is completed. The operator can hold the fixing plate 3 with one hand and the handle 16 with the other hand to pay out the line. When a trolley-type pay-out is needed, before installing the pay-out wheel 1 to the top of the vehicle body 4, first press the pressing rod 29 set at one end of the handle 16. The pressing rod 29 will compress the third spring 30 set on one side, and then the pressing rod 29 will drive the lower pressure sleeve 28 to move. Due to the special structural design of the lower pressure sleeve 28 and the clamping block 24, the lower pressure sleeve 28 moves downward and will gradually press the clamping block 24 into the inside of the clamping rod 26. Then, the handle 16 is pulled upward to remove the handle 16 from the pay-out wheel 1, and then the pay-out wheel 1 can be installed on the vehicle body 4 according to the above operation. When the handle 16 needs to be replaced, refer to the above process for operation.

[0042] In summary, when the entire device is in use or running: when a trolley-type pay-off is needed, first place the pay-off wheel 1 at the corresponding position on the vehicle body 4, then pass the clamping rod 7 through the clamping groove 8 opened on the fixing plate 3, and extend one end of the clamping rod 7 into the inner side of the clamping sleeve 9. During this process, the clamping block 10 will be squeezed by the inner wall of the clamping sleeve 9 and retracted into the inside of the clamping rod 7. At the same time, the clamping block 10 will compress the first spring 12 connected to one end. When the clamping block 10 can no longer be inserted into the inner side of the clamping sleeve 9, rotate the clamping rod 7. When the clamping block 10 corresponds to the position of the clamping hole 11, the first spring 12 will automatically reset and push the clamping block 10 into the clamping hole 11, so that the clamping block 10 and the clamping sleeve 9 can stably install the pay-off wheel 1 to the top of the vehicle body 4. At the same time, the limit plate 22 will fit with the side wall of the vehicle body 4, and then release a part of the line on the pay-off wheel 1, and pass the released line around the guide wheel 19 first, and then make the released line pass through the storage bin 18, and then push the vehicle body 4 through the push plate 6, and the vehicle body 4 will pass through the bottom set As the moving wheel 5 moves, the surface of the released line will be stained with lime powder after passing through the storage bin 18, thereby realizing automatic line drawing with lime and reducing the intensity of manual labor. When it is necessary to remove the pay-off wheel 1 from the vehicle body 4, first rotate the unlocking sleeve 13 counterclockwise, and the unlocking sleeve 13 will drive the unlocking groove 14 to rotate. Due to the special structural design of the unlocking groove 14, the clamping block 10 will be gradually pressed into the inner wall of the clamping sleeve 9, and at the same time, the limit block 20 provided on the inner side of the unlocking sleeve 13 will be in the limit groove 21 opened on the outer side of the clamping sleeve 9. Slide, when the unlocking sleeve 13 can no longer rotate, the clamping block 10 is just completely pressed into the inner wall of the clamping sleeve 9, and then the clamping rod 7 is rotated in the corresponding direction by the handle 23, and the clamping rod 7 will drive the clamping block 10 to rotate. Due to the special structural design of the guide groove 15, the clamping block 10 will be gradually pressed into the inside of the clamping rod 7 during the rotation, and then the clamping rod 7 is pulled outward by the handle 23, so that the clamping rod 7 is disengaged from the clamping sleeve 9, and then the spool 1 can be removed from the vehicle body 4.

[0043] When hand-held pay-off is needed, first remove the pay-off reel 1 from the vehicle body 4 according to the above process, then take out the appropriate grip 16, and then dock the corresponding end of the grip 16 with the clamping rod 26 set on one side of the pay-off reel 1, so that the clamping rod 26 is inserted into the inside of the grip 16. In this process, the clamping block 24 will be squeezed into the inner side of the clamping block 24, and at the same time, the clamping block 24 will cause the second spring 25 connected at one end to be compressed. When the position of the clamping block 24 corresponds to the position of the clamping groove 27, the second spring 25 will automatically reset, thereby pushing the clamping block 24 into the clamping groove 27, so that the clamping block 24 and the clamping groove 27 are engaged with each other, thereby making the handle 16 firmly installed on one side of the pay-off reel 1, and then the worker The staff can hold the fixing plate 3 with one hand and the handle 16 with the other hand to pay out the line. When a trolley-type pay-out is needed, before installing the pay-out wheel 1 to the top of the vehicle body 4, first press the pressing rod 29 provided at one end of the handle 16. The pressing rod 29 will compress the third spring 30 provided on one side, and then the pressing rod 29 will drive the lower pressure sleeve 28 to move. Due to the special structural design of the lower pressure sleeve 28 and the clamping block 24, the downward movement of the lower pressure sleeve 28 will gradually press the clamping block 24 into the inside of the clamping rod 26. Then, the handle 16 is pulled upward to remove the handle 16 from the pay-out wheel 1, and then the pay-out wheel 1 can be installed on the vehicle body 4 according to the above operation.
