Description

Technical Field

[0001] This invention relates to the field of highway engineering technology; specifically, it relates to a giant T-shaped clamp for fixing roadbed side ditch templates and its installation device. Background Technology

[0002] Currently, in the construction of highways or other types of roads, cast-in-place rectangular concrete side ditches are mainly used. The reinforcement of these rectangular side ditches with wooden formwork primarily involves using tie rods for reinforcement and dimensional positioning. This construction method requires drilling multiple holes in the wooden formwork, severely affecting its stress resistance and service life, increasing construction costs. Furthermore, its use is limited when there is insufficient support gap on the slope side. Additionally, it requires installing numerous tie rod holes in the formwork, resulting in a large workload, high labor and material costs, low efficiency, slow speed, and insufficient stability after reinforcement, thus impacting the construction efficiency of rectangular side ditches. Moreover, in formwork support operations, traditional methods rely on manual, individual support and fixing of each formwork, making the formwork support and fixing operations time-consuming, labor-intensive, and inefficient. Therefore, this application provides a giant T-shaped clamp and its installation device for fixing roadbed side ditch formwork. Summary of the Invention

[0003] In view of this, the present invention provides a giant clamp for fixing the template of the road cut ditch and its installation device. The clamp can fix four templates of the ditch at one time, and the clamp installation device can carry multiple clamps at one time and move on the top of the template, and can install them one by one according to the preset installation position, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0004] To achieve the aforementioned objective, a first aspect of the present invention provides a giant clamp for fixing roadbed ditch templates, comprising a horizontal plate, side rods, and a central rod. Each side rod is vertically fixed on one side of the bottom of the horizontal plate. The central rod has a "U" shape, with its top end fixed to the horizontal plate. The side rods are used to abut against the outer surface of the templates on the outer side, and the central rod is used to abut between the two templates located in the middle.

[0005] A second aspect of the present invention provides an installation device for a giant clamp for fixing a roadbed ditch template, comprising a frame-shaped traveling frame, wherein front rollers and rear rollers capable of traveling on top of the template are respectively provided on the front and rear sides of the traveling frame, the traveling frame having vertically distributed stacking racks inside, and an outlet for the clamp to fall out at the bottom of the stacking racks. Support shafts are fixedly installed on both sides of the bottom of the rear door of the stacking racks, and push plates are slidably fitted at both ends of the support shafts. The upper surface of the push plates is flush with the outlet. Baffles are rotatably installed on both sides of the traveling frame, and the rotation of the baffles... The center is located on the plane of its rear side in the front-back direction, and the rotation center of the baffle is flush with the top surface of the template in the height direction. When the push plate is in the rearmost position, the lowest clamp in the stacking rack can fall into the top of the template and fit against the rear side of the baffle.

When the push plate is in the frontmost position, its front end can swing downward around the support shaft and press on the top clamp of the template. The height of the baffle is less than the height of the top surface of the template, and the clamp in the stacking rack is supported by the push plate.

[0006] Optionally, slide blocks are slidably provided on both sides of the walking frame, and a rotating shaft is fixedly installed at the tail end of the push plate away from the support shaft. The front end of the slide block is rotatably sleeved on the rotating shaft. A transverse groove is provided inside the push plate. The end of the support shaft is located in the transverse groove. When the push plate is in the foremost position, the rotating shaft coincides with the support shaft.

[0007] Optionally, a circular plate is rotatably mounted on the walking frame, the center of the circular plate coincides with the center of the baffle, the outer side of the baffle is fixedly connected to the inner surface of the circular plate, a connecting rod is fixedly mounted on the outer side of the circular plate, a sliding plate is slidably mounted on the walking frame, the front side of the sliding plate is provided with a longitudinal groove sleeved on the outside of the connecting rod, the rear end of the sliding plate is located behind the slide block, and when the push plate is in the rearmost position, the baffle is in a vertical state by limiting the sliding plate.

[0009] Optionally, a support plate is fixedly sleeved on the outside of the inner rotating shaft. A middle roller is installed at the bottom end of the support plate. The rear roller is vertically mounted on the traveling frame. When the push plate is in a horizontal state and the middle roller is supported on the top of the template, the rear roller is located above the template and its height is greater than the height of the clamp inserted into the template. During the process of the push plate moving forward to the foremost position in a horizontal state, the rear roller descends and is supported on the top of the template. When the front end of the push plate swings downward to press down on the clamp so that it is inserted into the template, the rear roller maintains a constant height and the middle roller swings upward to above the clamp inserted into the template.

[0010] Optionally, a lifting sleeve is slidably disposed inside the walking frame. A screw with its top end rotatingly engaged with the walking frame is threadedly connected inside the screw sleeve. The rear roller is mounted on the screw sleeve. A gear is fixedly sleeved on the bottom end of the screw. A rack is meshed on one side of the gear, and the front end of the rack is fixedly connected to the slide block.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figure 1 As shown, the first aspect of the present invention provides a giant clamp for fixing the formwork of a road cutting ditch, including a horizontal plate 25, side rods 26, and a central rod 27. One side rod 26 is vertically fixed on each side of the bottom of the horizontal plate 25. The central rod 27 has a "U" shape, with its top end fixed to the horizontal plate 25. The side rods 26 abut against the outer surface of the outer formwork, and the central rod 27 abuts between the two central formwork sections. This clamp can simultaneously control and fix four formwork sections of the ditch, improving the stability and splicing effect of the formwork, effectively preventing formwork slippage and grout leakage, and improving the construction quality of the ditch. When supporting the formwork, the clamp can be directly inserted into the corresponding position of the formwork, making operation convenient.

[0023] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 10The second aspect of the present invention provides an installation device for a giant clamp for fixing a roadbed ditch template, comprising a frame-shaped traveling frame 1, with front rollers 2 and rear rollers 3 respectively provided on the front and rear sides of the traveling frame 1 for traveling on the top of the template; vertically distributed stacking racks 4 are provided inside the traveling frame 1, with an outlet 5 for the clamp to fall out at the bottom of the stacking racks 4; support shafts 6 are fixedly installed on both sides of the bottom of the rear door of the stacking racks 4, with push plates 7 slidably sleeved at both ends of the support shafts 6, the upper surface of the push plates 7 being flush with the outlet 5; and baffles 8 are rotatably installed on both sides of the traveling frame 1, the baffles 8 rotating... The center of motion is located on the plane of its rear side in the front-back direction, and the rotation center of the baffle 8 is flush with the top surface of the template in the height direction. When the push plate 7 is in the last side position, the lowest clamp in the stacking rack 4 can fall into the top of the template and fit against the rear side of the baffle 8. When the push plate 7 moves forward, it can push the clamp on the template to swing forward around the rotation center of the baffle 8 and insert it into the template. When the push plate 7 is in the foremost position, its front end can swing downward around the support shaft 6 and press on the top clamp of the template. The height of the baffle 8 is less than the height of the top surface of the template, and the clamp in the stacking rack 4 is supported by the push plate 7.

[0024] When in use, first place the walking frame 1 on top of the template, and then put the clamps to be installed into the stacking rack 4 from top to bottom through the top entrance of the stacking rack 4. At this time, the push plate 7 is supported in a horizontal state by the support shaft 6, and the clamp at the bottom of the stacking rack 4 is supported by the push plate 7.

[0025] When the bottom clamp needs to be inserted into the template for installation, the push plate 7 is moved backward so that it detaches from the bottom of the bottom clamp, causing the clamp to move downward under its own weight. Finally, the bottom clamp falls to the top of the template, and the front side of the bottom clamp contacts the baffle 8.

[0026] Then, the push plate 7 is moved forward, and the front end of the push plate 7 applies a forward pushing force to the bottom clamp, causing the bottom clamp to swing forward with its front side bottom end as the center. When the push plate 7 moves to the frontmost position, under the pressure of the clamp in the stacking rack 4, the front end of the push plate 7 will swing downward with the support shaft 6 as the center. During this process, the push plate 7 causes the bottom clamp to insert into the template to complete the installation.

[0027] Then, the push plate 7 is moved backward. Under the action of the support shaft 6, the push plate 7 will quickly swing to a horizontal state and support the bottom of the clamp inside the stacking rack 4, so that the clamp on the stacking rack 4 is in a suspended state. Then the baffle 8 is reset, and the traveling frame 1 can continue to be pushed forward to the next clamp installation position. In this way, the clamp installation operation is realized one by one.

[0028] After applying the above embodiments of this application, firstly, the walking frame 1 and stacking frame 4 can carry the measuring clamps at once and move conveniently and efficiently on top of the template, achieving rapid transfer of the clamps. Secondly, it can perform the installation operation of one clamp at a time, and the gravity of the clamps inside the stacking frame 4 provides sufficient pressure for the clamps being installed, ensuring that the clamps can be stably installed in place. Compared with the prior art, which relies on manual insertion of clamps into the template one by one, this method is more time-saving, labor-saving, and efficient.

[0029] Please refer to Figure 5 , Figure 8 and Figure 10 Both sides of the walking frame 1 are slidably provided with slide seats 9. The tail end of the push plate 7 away from the support shaft 6 is fixedly installed with a rotating shaft 10. The front end of the slide seat 9 is rotatably sleeved on the rotating shaft 10. A transverse groove 11 is provided in the push plate 7. The end of the support shaft 6 is located in the transverse groove 11. When the push plate 7 is in the foremost position, the rotating shaft 10 coincides with the support shaft 6.

[0030] The forward and backward movement of the push plate 7 can be achieved by controlling the forward and backward movement of the slide 9 on the traveling frame 1. When the push plate 7 is in any other position at the foremost position, the support shaft 6 and the rotating shaft 10 synchronously support the push plate 7 in a horizontal state. When the push plate 7 moves forward, the support shaft 6 is displaced backward within the transverse groove 11.

[0031] Please refer to Figure 5 A circular plate 12 is rotatably mounted on the walking frame 1. The center of the circular plate 12 coincides with the center of the baffle 8. The outer side of the baffle 8 is fixedly connected to the inner surface of the circular plate 12. A connecting rod 13 is fixedly mounted on the outer side of the circular plate 12. A sliding plate 14 is slidably mounted on the walking frame 1. A longitudinal groove 15 is provided on the front side of the sliding plate 14 and sleeved on the outside of the connecting rod 13. The rear end of the sliding plate 14 is located on the rear side of the slide block 9. When the push plate 7 is in the rearmost position, the baffle 8 is in a vertical state by limiting the sliding plate 14.

[0032] The baffle 8 is rotatably mounted on the walking frame 1 by means of the circular plate 12. The horizontality of the walking frame 1 is maintained by the front roller 2 and the rear roller 3. The circular plate 12 and the walking frame 1 are matched in the height direction so that when the walking frame 1 is placed on the top of the template, the center of the circular plate 12 can coincide with the bottom of the front side of the clamp that falls into the top of the template.

[0033] When the baffle 8 rotates under the pushing force applied to the clamp by the push plate 7, the connecting rod 13 moves within the longitudinal groove 15 while simultaneously pushing the slide plate 14 forward. Specifically, in this embodiment, the rotation range of the baffle 8 is 135°, so that after the baffle 8 rotates, it can be separated from the clamp inserted into the template, and the baffle 8 is supported in this state by the slide plate 14 through the connecting rod 13.

[0034] As the slide block 9 moves the push plate 7 backward, the slide block 9 pushes the slide plate 14 backward, causing the slide plate 14 to move the baffle 8 back to its initial state.

[0035] Furthermore, the arc trajectory of the connecting rod 13 is located below the horizontally positioned push plate 7, and the front end of the bottom surface of the push plate 7 is set in an arc shape. This arrangement ensures that the distance between the part of the push plate 7 that contacts the clamp and the center of the circular plate 12 is greater than the distance between the connecting rod 13 and the center of the circular plate 12. Consequently, when the baffle 8 swings at the same angle, the forward movement distance of the push plate 7 and the slide 9 is greater than the forward movement distance of the slide plate 14, thus ensuring that the slide 9 and the slide plate 14 do not interfere with each other.

[0036] Please refer to Figure 8 A support plate 16 is fixedly sleeved on the outside of the inner rotating shaft 10. A middle roller 17 is installed at the bottom end of the support plate 16. The rear roller 3 is raised and lowered on the walking frame 1. When the push plate 7 is in a horizontal state and the middle roller 17 is supported on the top of the template, the rear roller 3 is above the template and its height is greater than the height of the clamp inserted into the template. During the process of the push plate 7 moving forward to the frontmost position in a horizontal state, the rear roller 3 descends and is supported on the top of the template. When the front end of the push plate 7 swings down and presses down on the clamp so that it is inserted into the template, the rear roller 3 maintains a constant height and the middle roller 17 swings upward to above the clamp inserted into the template.

[0037] When the clamp is inserted into the template to complete the installation, the front end of the push plate 7 presses against the top of the clamp and the middle roller 17 disengages from the template, continuing to push the slide 9 forward. The slide 9 can drive the entire walking frame 1 to move forward. After the front end of the push plate 7 disengages from the top of the clamp, it will continue to swing downward under the pressure of the clamp in the stacking frame 4 and can be supported by the baffle 8. After that, the middle roller 17 can pass over the clamp that has been installed and move to the front of the clamp that has been installed.

[0038] Then, pull the slide block 9 backward. As the slide block 9 moves the push plate 7 backward, the push plate 7 will swing upward to a horizontal position and then move backward. After the push plate 7 swings upward to a horizontal position, the middle roller 17 can support the top of the template. When the slide block 9 continues to move backward, on the one hand, the rear roller 3 can move upward to disengage from the template and move in the height direction above the installed fixture. On the other hand, the slide block 9 resets the baffle 8 to its initial state through the slide plate 14.

[0039] When the front end of the push plate 7 moves into the outlet 5, it directly pushes the walking frame 1 and the slide 9 forward, causing the walking frame 1 to move forward as a whole, so that the rear roller 3 can pass over the installed fixture.

[0040] Please refer to Figure 6The walking frame 1 has a sliding sleeve 18 that can be raised and lowered. The sleeve 18 is threaded with a screw 19 whose top end is rotatably engaged with the walking frame 1. The rear roller 3 is installed on the sleeve 18. The bottom end of the screw 19 is fixedly fitted with a gear 20. One side of the gear 20 is meshed with a rack 21, and the front end of the rack 21 is fixedly connected to the slide block 9. When the push plate 7 is in the foremost and rearmost positions, the rack 21 is separated from the gear 20.

[0041] As the push plate 7 moves backward in a horizontal position until it reaches the outlet 5, the rack 21 and the gear 20 are engaged. As the rack 21 moves with the slide 9, it drives the gear 20 to rotate. The gear 20 drives the screw 19 to rotate. The screw 19 causes the sleeve 18 to move upward and drives the rear roller 3 to move upward to the highest position. At this time, the rack 21 passes over the gear 20 again and separates from the gear 20.

[0042] Please refer to Figure 3 Both the front roller 2 and the rear roller 3 have wheel grooves 22 that fit over the top of the template. The middle roller 17 is a columnar structure with a length greater than the width of the template. By setting the wheel grooves 22, the template can be used to limit and guide the movement of the traveling frame 1. At the same time, the traveling frame 1 and the stacking frame 4 are used to ensure that the clamps on the stacking frame 4 are aligned with the template and can be inserted into the template.

[0043] Please refer to Figure 2 The walking frame 1 includes a front frame 1-1 and a rear frame 1-2. The front roller 2 and the rear roller 3 are respectively installed on the front frame 1-1 and the rear frame 1-2. The tail end of the front frame 1-1 is slidably engaged with the rear frame 1-2 through the connecting plate 1-3. The front end of the front frame 1-1 is fixedly provided with a support plate 1-4 that supports the bottom of the front end of the lowest clamp.

[0044] By using the support plate 1-4 in conjunction with the push plate 7 to simultaneously support both ends of the bottom clamp, the stability of the clamp and the overall balance of the device can be improved. Before installing the bottom clamp inside the stacking rack 4, the front frame 1-1 is moved forward so that the support plate 1-4 is disengaged from the bottom of the bottom clamp inside the stacking rack 4.

[0045] Please refer to Figure 2 and Figure 9 The stacking rack 4 includes sleeve plates 4-1 that are respectively fitted onto both ends of the clamps and are arranged longitudinally. The rear sides of the two sleeve plates 4-1 are fixedly connected by a fixing plate 4-2, and the rear frame 1-2 is fixedly connected to the sleeve plates 4-1. The two sleeve plates 4-1 can limit the clamps in the width direction, so that all the clamps in the stacking rack 4 and the clamps that have been installed on the template are horizontally aligned.

[0046] Please refer to Figure 5The two slides 9 are fixedly connected by a timing plate 23, and handles 24 are fixedly installed on the outer side of the slides 9 and on both sides of the tail end of the walking frame 1.

[0047] The scope of the present invention is not limited to the contents of the above specification. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of the present invention, and all such modifications and variations should fall within the scope of the present invention.
