Description

Technical Field

[0001] This utility model belongs to the field of road and bridge engineering technology, and specifically relates to an adjustable cutting device for road and bridge construction. Background Technology

[0002] Contraction joints in concrete pavements are transverse, non-penetrating joints installed on the pavement slab to prevent irregular cracks caused by shrinkage during the hardening process and temperature drops. The joint width is no more than 1 cm, and the depth is 1 / 3 of the slab thickness. Contraction joints in plain concrete pavements are typically spaced 4-7 m apart, usually at equal intervals, but can also be arranged at unequal intervals. Contraction joints are mostly perpendicular to the direction of traffic, but can also be arranged diagonally. They are constructed using the pressure joint method before the concrete initially sets, and are mostly cut using a joint saw.

[0003] Currently, when cutting seams, workers usually move the seam saw to perform the cutting operation. However, in this way, the workers completely control the forward direction of the seam saw during the construction process. If the operation is not done properly, it can easily cause the sawing direction of the contraction seam to deviate. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figure 1-5 The present invention provides the following technical solution: an adjustable cutting device for road and bridge construction, comprising a vehicle body 1 and a sawing machine 2, wherein a slide rail 3 and two fixing blocks 4 are fixedly connected to both sides of the upper surface of the vehicle body 1, a first bearing 5 is embedded in the surface of the fixing block 4, a rotating shaft 6 is provided inside the first bearing 5, a threaded column 7 is fixedly provided between the two rotating shafts 6, a threaded cylinder 8 is threadedly connected to the surface of the threaded column 7, the threaded cylinder 8 is embedded in the side of the bearing block 9, and the bearing block 9 slides on the upper surface of the vehicle body 1;

[0023] By means of the above structure or mechanism, the arrangement of the first bearing 5 and the rotating shaft 6 can make the rotation of the threaded column 7 more stable, thereby facilitating the change of the position of the support plate 13.

[0024] A drive motor 10 is mounted on the lower surface of the vehicle body 1. A transmission wheel 11 is respectively provided on the surface of the output shaft of the drive motor 10 and the surface of the output shaft of the rotating shaft 6 on one side. The two transmission wheels 11 are connected by a belt 12. A support plate 13 is fixedly connected to the side of the bearing block 9. The other side of the support plate 13 is slidably connected to the slide rail 3. The upper surface of the support plate 13 is fixedly connected to the lower surface of the fixed plate 15 through a first electric push rod 14. A groove 16 is opened on the lower surface of the fixed plate 15. A mounting seat 17 is slidably connected in the groove 16. The sawing machine 2 is set in the mounting seat 17.

[0025] By means of the above structure or mechanism: controlling the working state of the drive motor 10, the threaded column 7 can rotate, causing the threaded cylinder 8 to move the support plate 13, which can drive the sawing machine 2 to move to perform the cutting work.

[0026] Specifically, positioning blocks 18 are fixedly connected to both sides of the mounting base 17. The positioning blocks 18 are fixedly connected to the fixing rod 20 via the second electric push rod 19. The fixing rod 20 is fixedly connected to the lower surface of the fixing plate 15. The lower surface of the vehicle body 1 is provided with moving wheels 21.

[0027] By controlling the working state of the second electric push rod 19 through the above structure or mechanism, the position of the mounting base 17 can be changed, and thus the position of the sawing machine 2 can be changed.

[0028] Specifically, a second bearing 23 is provided on the surface of the wheel axle 22 inside the movable wheel 21 on one side. The second bearing 23 is embedded in the side of the connecting plate 24. A support rod 25 is hinged on the other side of the connecting plate 24. The two ends of the support rod 25 are fixedly connected to the support seat 26. Support blocks 27 are fixedly connected to the lower surface of the vehicle body 1 and the upper surface of the connecting plate 24 respectively. A connecting block 28 is hinged in each of the two support blocks 27. The two connecting blocks 28 are fixedly connected by a third electric push rod 29.

[0029] With the above structure or mechanism, when the third electric push rod 29 changes its working state, the position of the support seat 26 can be changed through the hinged support rod 25 and connecting block 28, so that the support seat 26 can contact the ground and support one side of the vehicle body 1. At this time, it is convenient to place the vehicle body 1 stably, and the cutting work can be carried out without considering the cutting depth.

[0030] Specifically, a handle 30 is provided on the upper surface of the vehicle body 1, and a storage box 31 is provided on the lower surface of the vehicle body 1.

[0031] With the above structure or mechanism, the handle 30 allows the staff to easily push the vehicle body 1 to move, and the storage box 31 can hold tools and batteries.

[0032] The working principle of this utility model is as follows:

[0033] When in use, move the device to a suitable position. When the vehicle body 1 is no longer in position, control the working state of the second electric push rod 19 through the control system (not shown in the figure). During the extension or retraction of the second electric push rod 19, the mounting base 17 can be driven to slide in the slide groove 16, thereby changing the position of the sawing machine 2. Then, control the working state of the first electric push rod 14 through the control system. During the extension or retraction of the first electric push rod 14, the sawing machine 2 can be moved closer to the ground to perform kerf cutting. Then, control the drive motor 10 to work, which can rotate the threaded column 7, thereby moving the sawing machine 2 through the support plate 13. When the kerf depth is not considered, control the working state of the third electric push rod 29 through the control system. When the third electric push rod 29 is extended, the support base 26 can be moved closer to the ground. After the nearby moving wheel 21 separates from the ground, the sawing machine 2 can continue to perform kerf cutting. At this time, the support base 26 can increase the friction with the ground.
