DETAILED DESCRIPTION

[0018] In order to make those skilled in the art better understand the present invention, the present invention is further clearly and completely described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the features in the embodiments and examples of this application can be combined with each other.

[0019] refer to Figures 1 to 9A typical embodiment of the present invention provides a roadbed repair casting formwork transfer and laying device, comprising a traveling box 1, a revolving belt 2 is provided at the top and bottom of the traveling box 1, a placement groove 3 for accommodating the end of the formwork is provided on the revolving belt 2, a formwork outlet 4 is provided at the front end of the traveling box 1, a large arm 5 is provided on the side of the traveling box 1, a small arm 6 is movably connected to one end of the large arm 5, a driving component 7 for controlling the lateral extension and retraction of the small arm 6 is provided on the large arm 5, a gantry 8 is fixedly provided at the front end of the small arm 6, a telescopic block 9 for cooperating with the top of the gantry 8 to fix the top of the formwork is provided on the side of the top of the gantry 8 facing the traveling box 1, a bracket 10 for supporting the bottom of the formwork is provided on the side of the bottom of the gantry 8 facing the traveling box 1, and a side push component 11 for driving the bracket 10 to move toward the side of the traveling box 1 and withdraw the bottom of the formwork is provided on the side of the gantry 8.

[0020] Based on the forward direction of the traveling box 1, the front face of the traveling box 1 is provided with an opening for placing the template into the traveling box 1. The template in the traveling box 1 is placed between the two rotating belts 2, and the top and bottom of the template are respectively located in the corresponding placement grooves 3, so that the template is stably supported in a state perpendicular to the rotating belts 2. Among them, a template located at the template outlet 4 is located in the door frame 8 and the bottom is supported by the bracket 10, and the telescopic block 9 cooperates with the top of the door frame 8 to limit the template.

[0021] The small arm 6 is extended outward on the big arm 5 through the driving assembly 7. At this time, the telescopic block 9 cooperates with the door frame 8 to stably push the template out of the rotating belt 2. At this time, the rotating belt 2 rotates along with the displacement of the template. After the template is separated from the rotating belt 2, it is stably supported from the bottom by the bracket 10, and cooperates with the telescopic block 9 and the door frame 8 to keep the template stable during the extension of the small arm 6.

[0022] When the template is delivered to the designated position, the side push assembly 11 moves the bracket 10 toward the side of the traveling box 1, so that the bracket 10 is pulled away from the bottom of the template on the gantry 8, so that the template falls to the ground, and the template lowering operation is completed. Then, the driving assembly 7 retracts the arm 6 to the initial position. At this time, the next template to be lowered can be moved into the gantry 8 by the rotation of the revolving belt 2. The top of the template squeezes the telescopic block 9, so that the telescopic block 9 shrinks upward to provide space for the template to enter the inner side of the gantry 8.

[0023] In this embodiment, through the above-mentioned settings and combined with the displacement of the walking box 1, the templates can be transferred and lowered one by one along the pouring direction of the roadbed. Compared with the prior art that relies on manual transportation of the templates, the transfer and laying of the templates are more efficient and more time-saving and labor-saving.

[0024] In a relatively specific embodiment, Figure 1 , Figure 7As shown, the driving assembly 7 includes a screw 7.1 and a threaded sleeve 7.2. The screw 7.1 is rotatably mounted on the outside of the upper arm 5. The threaded sleeve 7.2 is threadedly sleeved on the outside of the screw 7.1. A first strip groove 12 is opened on the outside of the upper arm 5. One end of the threaded sleeve 7.2 toward the forearm 6 passes through the first strip groove 12 and is fixedly connected to the forearm 6.

[0025] By rotating the screw rod 7.1, the threaded sleeve 7.2 will be displaced in the first strip groove 12, and the threaded sleeve 7.2 will drive the small arm 6 to be displaced, thereby realizing the external delivery of the template and the reset of the small arm 6 and the door frame 8.

[0026] In another relatively specific embodiment, the telescopic block 9 includes a wedge block 9.1 and a limit spring 9.2. The wedge block 9.1 is slidably mounted on the door frame 8 in the height direction, and the limit spring 9.2 is connected between the top of the wedge block 9.1 and the door frame 8. The wedge block 9.1 can cooperate with the door frame 8 to have a stable limit effect on the top of the template. When the arm 6 retracts and the door frame 8 is reset, the inclined surface of the wedge block 9.1 is subjected to the pressure of the top of the next template to be laid, so that the wedge block 9.1 automatically compresses the spring and is stored in the door frame 8. When the template enters the door frame 8, the wedge block 9.1 automatically extends under the action of the limit spring 9.2 and cooperates with the door frame 8 to limit the two sides of the top of the template.

[0027] In a preferred embodiment, the arm 5 is tilted downward toward the end close to the template outlet 4, and the gantry 8 is perpendicular to the arm 5. During the extension of the arm 6, the height of the template being sent out will continue to decrease, and then, when the template is lowered, the height of the template from the ground is relatively small, so that the height of the template when it is lowered is relatively low, thereby preventing damage to the template.

[0028] In a preferred embodiment, Figure 3 As 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 door frame 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.

[0029] After the forearm 6 is extended, the bottom of the lifting plate 11.1 is subjected to resistance from the ground, so that the lifting plate 11.1 is forced to move upward. At this time, the lifting plate 11.1 drives the lifting rail 11.2 to move upward. The lifting rail 11.2 applies a force to the push rod 11.3 on the opposite side, so that the bracket 10 moves toward the side of the walking box 1, thereby achieving the effect of automatically pulling the bracket 10 away from the bottom of the template.

[0030] In this embodiment, Figure 8As shown, a support wheel 13 is provided at the bottom of the lifting plate 11.1. The end of the boom 5 away from the template outlet 4 is rotatably mounted on the walking box 1, and a pull-down spring 14 is provided between the bottom of the end of the boom 5 away from the template outlet 4 and the walking box 1. In the process of extending the small arm 6, the support wheel 13 contacts the ground instead of the lifting plate 11.1, and the support wheel 13 rolls on the ground. By rotatably mounting the boom 5 on the walking box 1, the height and inclination angle of the small arm 6 and the gantry 8 can be adjusted by rotating the boom 5. When the small arm 6 tilts upward due to uneven ground, the boom 5 can be rotated downward to make up for the deviation caused by the uneven ground.

[0031] In a relatively specific embodiment, the lifting rail 11.2 is provided with a first track groove 11.4 and a second track groove 11.5, the first track groove 11.4 is parallel to the upper arm 5, one end of the second track groove 11.5 is connected to 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, and the lifting plate 11.1 is provided with a lock hole 15, and a lock rod 16 is inserted in the lock hole 15, and the lock rod 16 is slidably arranged in the lower arm 6. Figure 2 As shown, a second strip groove 17 is provided on the side of the small arm 6, an inner stopper 18 is slidably installed in the second strip groove 17, the inner end of the inner stopper 18 is fixed to the small arm 6, and the outer end of the inner stopper 18 passes through the first strip groove 12, an outer stopper 19 is fixedly provided on the side of the lock rod 16 facing the template, and a third strip groove 20 (for the displacement of the outer stopper 19) is provided on the side of the small arm 6 facing the template Figure 8 ).

[0032] In the initial state, the side push rod 11.3 is located in the first track groove 11.4, at which time, the bracket 10 and the lifting rail 11.2 are locked with each other in the height direction, thereby improving the stability of the support of the template by the bracket 10. The locking rod 16 is inserted into the locking hole 15, and the locking rod 16 locks the lifting plate 11.1 in the height direction.

[0033] After the small arm 6 is extended to the point where the inner stopper 18 contacts the end of the first strip groove 12 close to the door frame 8, as the small arm 6 is continuously extended, the inner stopper 18 is blocked by the large arm 5, so that 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 stopper 19 also remains stationary, so that when the door frame 8 pushes the template to continue to move in the direction of the small arm 6, the bracket 10 is continuously pulled away from the bottom of the template until the locking rod 16 is pulled out of the lock hole 15, and the lifting plate 11.1 is displaced upward by the pressure of the ground, and the bracket 10 is pulled away from the bottom of the template, and the template falls, realizing the lowering of the template. In the process of the locking rod 16 being pulled out of the lock hole 15, the side push rod 11.3 moves from the first track groove 11.4 to the connection point between the first track groove 11.4 and the second track groove 11.5, and in the process of the lifting plate 11.1 moving upward, the side push rod 11.3 moves in the second track groove 11.5.

[0034] In addition, when the forearm 6 is extended, the support wheel 13 is stably supported on the ground, which can effectively support the traveling box 1. When the ground is inclined, the support of the support wheel 13 can prevent the traveling box 1 from tipping over.

[0035] An upward pull spring 21 is provided between the top of the lifting plate 11.1 and the door frame 8, a sleeve groove 22 is provided in the lifting plate 11.1, a sleeve block 23 is fixedly provided on the side of the door frame 8, the sleeve groove 22 is slidably sleeved on the outside of the sleeve block 23, and the lock hole 15 penetrates the lifting plate 11.1 and the sleeve block 23 at the same time. The upward pull spring 21 provides elastic force for the upward displacement of the lifting plate 11.1, and the cooperation of the sleeve block 23 and the sleeve groove 22 stably slides and installs the lifting plate 11.1 on the door frame 8. After the template is lowered, the elastic force of the upward pull spring 21 keeps the lifting plate 11.1 at the highest position, and at this time, the bracket 10 is in a state of being away from the door frame 8.

[0036] During the retraction of the forearm 6, the side of the bracket 10 away from the door frame 8 contacts the edge of the template outlet 4. As the forearm 6 continues to retract, the bracket 10 cannot continue to move in the direction of the retraction of the forearm 6. At this time, the side push rod 11.3 applies a force to the second track groove 11.5 to move the lifting rail 11.2 downward, and the lifting rail 11.2 drives the lifting plate 11.1 downward. When the side push rod 11.3 moves to the connecting point of the first track groove 11.4 and the second track groove 11.5, the lifting plate 11.1 drops 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 forearm 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 to the bottom of the door frame 8.

[0037] In a relatively specific embodiment, Fig. 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 Fig. 9 shown, the connecting portion 10.1 is in a "C" shape, and the two supporting portions 10.2 are in an "L" shape.

[0038] In addition, as Figure 4 shown, a limiting plate 24 is fixedly provided at the top of the gantry 8. The limiting 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.

[0039] The scope of protection required 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 changes. 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.
