Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the present invention, the following further clearly and completely describes the present invention with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the implementation manners and features in the embodiments of the present application may be combined with each other.

[0028] Refer to Figures 1 to 9, An apparatus for transporting and laying a roadbed repair casting formwork provided by a typical embodiment of the present invention includes a walking box 1. At the top and bottom inside the walking box 1, there are rotary belts 2 provided. On the rotary belts 2, there are placement grooves 3 for accommodating the ends of the formwork. At the front end of the walking box 1, there is a formwork outlet 4. On the side of the walking box 1, there is a boom 5. One end of the boom 5 is movably inserted with a forearm 6. On the boom 5, there is a driving assembly 7 for controlling the lateral expansion and contraction of the forearm 6. At the front end of the forearm 6, a gantry 8 is fixedly provided. On one side of the top of the gantry 8 facing the walking box 1, there is a telescopic chuck 9 for cooperating with the top of the gantry 8 to fix the top of the formwork. On one side of the bottom of the gantry 8 facing the walking box 1, there is a bracket 10 for supporting the bottom of the formwork. On the side of the gantry 8, there is a side push assembly 11 for driving the bracket 10 to displace towards the walking box 1 to withdraw from the bottom of the formwork.

[0029] Based on the forward direction of the walking box 1, on the front end face of the walking box 1, there is an open mouth for putting the formwork into the walking box 1. The formwork located inside the walking box 1 is placed between the two rotary belts 2, and the top and bottom of the formwork are respectively located in the corresponding placement grooves 3, so that the formwork is stably supported in a state perpendicular to the rotary belts 2. Among them, one formwork located at the formwork outlet 4 is located inside the gantry 8 and its bottom is supported by the bracket 10, and the telescopic chuck 9 cooperates with the top of the gantry 8 to limit the position of the formwork.

[0030] By the driving assembly 7, the forearm 6 extends outward on the boom 5. At this time, the telescopic chuck 9 cooperates with the gantry 8 to stably push the formwork out from the rotary belt 2. At this time, the rotary belt 2 rotates along with the displacement of the formwork. After the formwork is separated from the rotary belt 2, it is stably supported from the bottom by the bracket 10, and in cooperation with the telescopic chuck 9 and the gantry 8, the formwork can be kept stable during the extension of the forearm 6.

[0031] When the formwork is transported to the designated position, through the side push assembly 11, the bracket 10 is moved towards the walking box 1, so that the bracket 10 withdraws from the bottom of the formwork on the gantry 8, causing the formwork to fall to the ground and realizing the lowering operation of the formwork. Then, through the driving assembly 7, the forearm 6 retracts to the initial position. At this time, the next formwork to be lowered can be displaced towards the inside of the gantry 8 by the rotation of the rotary belt 2. The top of the formwork squeezes the telescopic chuck 9, causing the telescopic chuck 9 to contract upward to provide space for the formwork to enter the inside of the gantry 8.

[0032] In this embodiment, through the above settings and combined with the displacement of the walking box 1, the transportation and individual lowering operations of the formwork can be realized along the pouring direction of the roadbed. Compared with the prior art that relies on manual lifting of the formwork, the transportation and laying efficiency of the formwork is higher, and it is more time-saving and labor-saving.

[0033] In a relatively specific embodiment, such as Figure 1 , Figure 7As shown, the driving assembly 7 includes a lead screw 7.1 and a lead nut 7.2. The lead screw 7.1 is rotatably installed on the outer side of the boom 5, and the lead nut 7.2 is threadedly sleeved outside the lead screw 7.1. A first strip-shaped groove 12 is formed on the outer side of the boom 5, and one end of the lead nut 7.2 facing the forearm 6 passes through the first strip-shaped groove 12 and is fixedly connected to the forearm 6.

[0034] By rotating the lead screw 7.1, the lead nut 7.2 will displace within the first strip-shaped groove 12, and the lead nut 7.2 will drive the forearm 6 to displace, thereby realizing the outward delivery of the formwork and the reset of the forearm 6 and the gantry 8.

[0035] In another relatively specific embodiment, the telescopic chuck 9 includes a wedge block 9.1 and a limiting spring 9.2. The wedge block 9.1 is slidably installed on the gantry 8 in the height direction, and the limiting spring 9.2 is connected between the top of the wedge block 9.1 and the gantry 8. The wedge block 9.1 can cooperate with the gantry 8 to have a stable limiting effect on the top of the formwork. During the retraction of the forearm 6 and the reset of the gantry 8, the inclined surface of the wedge block 9.1 is pressed by the top of the next formwork to be laid, so that the wedge block 9.1 automatically compresses the spring and is received into the gantry 8. After the formwork enters the gantry 8, the wedge block 9.1 automatically extends under the action of the limiting spring 9.2 and cooperates with the gantry 8 to limit both sides of the top of the formwork.

[0036] In a preferred embodiment, one end of the boom 5 close to the formwork outlet 4 is inclined downward, and the gantry 8 is perpendicular to the boom 5. During the extension of the forearm 6, the height of the outwardly delivered formwork will continuously decrease. Furthermore, when the formwork is lowered, the height of the formwork from the ground is relatively small, so that the falling height of the formwork when it is lowered is relatively low, preventing damage to the formwork.

[0037] In a preferred embodiment, as Figure 3 shown, the side push assembly 11 described above includes a lifting plate 11.1, a lifting rail 11.2 and a side push rod 11.3. The lifting plate 11.1 is slidably installed on the side of the gantry 8 in the height direction. The lifting rail 11.2 is fixed on the side of the lifting plate 11.1 facing the walking box 1. The side push rod 11.3 is slidably installed in the lifting rail 11.2, and one end of the side push rod 11.3 is fixedly connected to the bracket 10.

[0038] After the forearm 6 extends, the bottom of the lifting plate 11.1 is resisted by the ground, so that the lifting plate 11.1 will be forced to displace upward. At this time, the lifting plate 11.1 drives the lifting rail 11.2 to displace upward. The lifting rail 11.2 exerts a force on the side push rod 11.3, so that the bracket 10 moves towards the walking box 1, achieving the effect of automatically withdrawing the bracket 10 from the bottom of the formwork.

[0039] In this embodiment, as Figure 8As shown, support wheels 13 are provided at the bottom of the lifting plate 11.1. One end of the boom 5 away from the template outlet 4 is rotatably mounted on the traveling box 1, and a downward pull spring 14 is provided between the bottom of the end of the boom 5 away from the template outlet 4 and the traveling box 1. During the extension of the forearm 6, the support wheels 13 replace the lifting plate 11.1 to contact the ground, and the support wheels 13 roll on the ground. By rotatably mounting the boom 5 on the traveling box 1, the height and tilt angle of the forearm 6 and the gantry 8 can be adjusted by rotating the boom 5. When the forearm 6 tilts upward due to uneven ground, the boom 5 can be rotated downward to make the forearm 6 rotate downward to compensate for the deviation caused by uneven ground.

[0040] In a relatively specific embodiment, a first track groove 11.4 and a second track groove 11.5 are provided in the lifting track 11.2. The first track groove 11.4 is parallel to the boom 5. One end of the second track groove 11.5 communicates with the first track groove 11.4, and the end of the second track groove 11.5 away from the first track groove 11.4 is inclined downward. A lock hole 15 is provided in the lifting plate 11.1, and a lock rod 16 is inserted into the lock hole 15. The lock rod 16 slidably passes through the forearm 6. As Figure 2 shown, a second strip-shaped groove 17 is provided on the side surface of the forearm 6. An inner stop block 18 is slidably mounted in the second strip-shaped groove 17. The inner end of the inner stop block 18 is fixed to the forearm 6, and the outer end of the inner stop block 18 penetrates through the first strip-shaped groove 12. An outer stop block 19 is fixedly provided on the side surface of the lock rod 16 facing the template. A third strip-shaped groove 20 for the displacement of the outer stop block 19 is provided on the side of the forearm 6 facing the template ( Figure 8 ).

[0041] In the initial state, the side push rod 11.3 is located in the first track groove 11.4. At this time, the bracket 10 and the lifting track 11.2 are locked with each other in the height direction, improving the stability of the bracket 10 in supporting the template. The lock rod 16 is inserted into the lock hole 15, and the lock rod 16 locks the lifting plate 11.1 in the height direction.

[0042] After the small arm 6 extends until the inner stop block 18 contacts the end of the first strip groove 12 close to the gantry 8, as the small arm 6 continues to extend, since the inner stop block 18 is blocked by the large arm 5, the locking rod 16 will not continue to move forward with the small arm 6. At this time, the locking rod 16 remains stationary, and the outer stop block 19 also remains stationary. When the gantry 8 pushes the template to continue to displace in the direction of the extension of the small arm 6, the bracket 10 is in a state of continuously being pulled out from the bottom of the template. Until the locking rod 16 is pulled out of the locking hole 15, the lifting plate 11.1 will be displaced upward under the pressure of the ground, the bracket 10 is pulled out from the bottom of the template, and the template falls, realizing the lowering of the template. Among them, during the process of the locking rod 16 being pulled out of the locking hole 15, the side push rod 11.3 moves from the first track groove 11.4 to the connection of the first track groove 11.4 and the second track groove 11.5. During the upward displacement of the lifting plate 11.1, the side push rod 11.3 is displaced in the second track groove 11.5.

[0043] In addition, during the extension of the small arm 6, the support wheel 13 stably supports on the ground and can effectively support the walking box 1. When the ground is inclined, with the support of the support wheel 13, the walking box 1 can be prevented from tipping over.

[0044] A tension spring 21 is arranged between the top of the lifting plate 11.1 and the gantry 8. A sleeve groove 22 is formed in the lifting plate 11.1. A sleeve block 23 is fixedly arranged on the side of the gantry 8. The sleeve groove 22 is slidably sleeved outside the sleeve block 23. The locking hole 15 penetrates through the lifting plate 11.1 and the sleeve block 23 at the same time. The tension spring 21 provides an elastic force for the upward displacement of the lifting plate 11.1. The cooperation of the sleeve block 23 and the sleeve groove 22 stably slidably mounts the lifting plate 11.1 on the gantry 8. After the template is lowered, the elastic force of the tension spring 21 keeps the lifting plate 11.1 at the highest position. At this time, the bracket 10 is in a state away from the gantry 8.

[0045] During the retraction of the small arm 6, the side of the bracket 10 away from the gantry 8 contacts the edge of the template outlet 4. As the small arm 6 continues to retract, the bracket 10 cannot continue to displace in the direction of the retraction of the small arm 6. At this time, the side push rod 11.3 exerts a force on the second track groove 11.5 to make the lifting rail 11.2 move downward. The lifting rail 11.2 drives the lifting plate 11.1 to move downward. When the side push rod 11.3 moves to the connection of the first track groove 11.4 and the second track groove 11.5, the lifting plate 11.1 descends to the lowest position. At this time, the locking hole 15 is aligned with the locking rod 16 in the axial direction of the locking rod 16. As the small arm 6 continues to retract, the locking rod 16 is reinserted into the locking hole 15 to lock the lifting plate 11.1 at the lowest position. At the same time, the bracket 10 moves below the gantry 8.

[0046] In a relatively specific embodiment, such as Figure 9As shown, the bracket 10 includes a connecting portion 10.1 and two supporting portions 10.2. A pallet for supporting the bottom of the formwork is provided at the bottom of the supporting portion 10.2. The top and bottom of the supporting portion 10.2 are both slidably engaged with the gantry 8. The two ends of the connecting portion 10.1 are respectively connected to the tops of the two supporting portions 10.2. Specifically, as Figure 9 shown, the connecting portion 10.1 is in the shape of a "C", and the two supporting portions 10.2 are in the shape of an "L".

[0047] In addition, as Figure 4 shown, a limit plate 24 is fixedly provided at the top of the gantry 8. The limit plate 24 can cooperate with the telescopic latch 9 to effectively limit the formwork and prevent the formwork from tipping over from the gantry 8.

[0048] The scope of protection claimed by the present invention is not limited to the above specific embodiments. For those skilled in the art, the present invention can have various deformations and modifications. Any modifications, improvements, and equivalent replacements made within the concept and principle of the present invention should be included within the scope of protection of the present invention.
