[0034] The following combines Figures 1 - 3 to describe the specific structure and working principle of the movable mobile formwork awning of the present utility model.

[0035] like Figure 1 and Figure 2 As shown, the movable movable formwork canopy includes two guide rails 100, a plurality of bracket components 200 and a rainproof cloth 400. The two guide rails 100 are arranged at intervals on the upper part of the movable formwork along the first direction and extend along the second direction. The plurality of bracket components 200 are arranged at intervals along the second direction. The bracket components 200 include two columns 210, an arch assembly 220 and two rolling supports 230. The two rolling supports 230 are arranged one-to-one on the two guide rails 100 and roll with the guide rails 100. A limiting mechanism is arranged on the rolling support 230, and the limiting mechanism is used to prevent the rolling support 230 from separating from the guide rail 100. The two columns 210 are arranged at intervals along the first direction, and the lower ends of the two columns 210 are connected to the two rolling supports 230 one-to-one. The two ends of the arch assembly 220 are connected to the upper ends of the two columns 210 one-to-one. The rainproof cloth 400 covers the upper part of the plurality of arch assemblies 220.

[0036] The movable formwork canopy provided by the utility model realizes the mobility of the canopy through the rolling cooperation between the rolling support 230 and the guide rail 100. The canopy can be moved to the construction site as needed to provide shade or rain protection, thereby preventing the concrete from being affected by sunlight or rain and improving the quality of the concrete. The limiting mechanism and the guide rail 100 can prevent the rolling support 230 from separating from the guide rail 100, thereby improving the safety of the canopy.

[0037] In one embodiment of the utility model, two guide rails 100 are arranged in parallel, and the distance between the two guide rails 100 is less than the length of the arch assembly 220, so that the arch assembly 220 extends to both sides, increasing the coverage area of ​​the canopy. Preferably, the cross section of the guide rail 100 is I-shaped, so that limiting grooves are formed on both sides of the guide rail 100, and the limiting mechanism is limitedly matched with the limiting grooves.

[0038] In one embodiment of the present invention, Figure 1 As shown, the distance between two adjacent support components 200 is equal, and the structure of each support component 200 is the same. The arch frame assembly 220 includes an arch frame 231 and a cross beam 232. The arch frame 231 is in an inverted V shape. The two ends of the arch frame 231 are welded and connected to the two ends of the cross beam 232 in a one-to-one correspondence. The arch frame 231 and the cross beam 232 form a triangular frame. The rainproof cloth 400 covers the upper part of the multiple arch frames 231. Since the arch frames 231 are inclined, the rainproof cloth 400 forms an inclined surface under the support of the arch frames 231, which can quickly drain the rainwater falling on the rainproof cloth 400.

[0039] In one embodiment of the present invention, Figure 2As shown, multiple connecting rods 233 are provided between the arch frame 231 and the cross beam 232 to increase the structural strength of the support member 200. The arch frame 231 is made of a φ60mm steel pipe and a φ50mm steel pipe. The cross beam 232 is made of a 5*10cm square steel, and the length of the cross beam 232 is 33.4m.

[0040] In an embodiment of the present invention, as Figure 1 shown, the movable mobile formwork awning further includes a plurality of connecting members 300. One connecting member 300 is provided between two adjacent columns 210. One end of the connecting member 300 is connected to one of the two adjacent columns 210, and the other end of the connecting member 300 is connected to the other of the two adjacent columns 210. By using the connecting member 300 to connect two adjacent columns 210 together, the structural strength between two adjacent columns 210 is effectively enhanced.

[0041] Specifically, the connecting part includes two connecting pipes which are arranged crosswise, and the middle parts of the two connecting pipes are connected by bolts. One end of each of the two connecting pipes is connected to one of the two adjacent columns 210 by bolts, and the other end of each of the two connecting pipes is connected to the other of the two adjacent columns 210 by bolts.

[0042] In an embodiment of the present invention, the connecting member 300 is detachably connected to the column 210. Specifically, the connecting member 300 and the column 210 can be connected by bolts, or can be connected by fasteners, or other detachable connection methods can also be adopted. By detachably connecting the connecting member 300 to the column 210, the disassembly of the connecting member 300 can be facilitated. After the connecting member 300 is disassembled, two adjacent columns 210 can approach or move away from each other, thereby realizing the opening and folding of the awning. The folded awning can be conveniently transported.

[0043] In an embodiment of the present invention, the support member 200 further includes a plurality of guy ropes (not shown). A plurality of guy ropes are provided between two adjacent arch frame assemblies 220, and the plurality of guy ropes are arranged at intervals in the first direction. Since when the distance between two adjacent arch frame assemblies 220 is too large, the rainproof cloth 400 will sag downward, and the sagging part is prone to water accumulation. Therefore, arranging guy ropes between two adjacent arch frame assemblies 220 can support the upper rainproof cloth 400. The guy ropes are in a taut state, enhancing the support for the rainproof cloth 400, preventing the rainproof cloth 400 from sagging to accommodate water accumulation, and moreover, during the transportation of the awning, the guy ropes will not affect the normal folding of the awning.

[0044] In an embodiment of the present invention, as Figure 3As shown, the rolling support 230 includes a support body 231, rolling wheels 232 and a rotating shaft 233. The lower end of the column 210 is connected to the support body 231. The guide rail 100 passes through the support body 231. Both ends of the rotating shaft 233 are connected to the support body 231. The rolling wheels 232 are rotatably sleeved on the rotating shaft 233 and are in rolling cooperation with the guide rail 100.

[0045] Specifically, the support body 231 includes a fixed plate and two connecting plates. The fixed plate is horizontally arranged, and the two connecting plates are vertically arranged. The two connecting plates are respectively located on both sides of the guide rail 100. Both ends of the fixed plate are welded to the upper ends of the two connecting plates. The fixed plate and the two connecting plates form an inverted U-shaped frame body. Of course, the fixed plate can also be integrally formed with the two connecting plates. The rotating shaft 233 is horizontally arranged. One end of the rotating shaft 233 is connected to one connecting plate, and the other end of the rotating shaft 233 is connected to the other connecting plate. An annular limiting groove is provided on the outer peripheral surface of the rolling wheel 232. The guide rail 100 is located in the annular limiting groove. The annular limiting groove can prevent the rolling wheel 232 from derailing during the movement along the guide rail 100.

[0046] In an embodiment of the present invention, as Figure 3 shown, the rolling support 230 further includes two limiting plates 234. The limiting plates 234 are arranged on both sides of the rolling wheel 232 and are connected to the support body 231. Specifically, the two limiting plates 234 are arranged at intervals along the first direction. The two limiting plates 234 are located on both sides of the rolling wheel 232. The distance between the two limiting plates 234 is slightly greater than the width of the rolling wheel 232. The two limiting plates 234 are welded to the fixed plate. The rotating shaft 233 passes through the two limiting plates 234, further strengthening the connection between the support body 231 and the rotating shaft 233. During the rolling of the rolling wheel 232, the limiting plates 234 prevent the rolling wheel 232 from moving axially along the rotating shaft 233, improving the stability of the rolling support 230 during the movement.

[0047] In an embodiment of the present utility model, the limiting mechanism includes two limiting rods 235. The two limiting rods 235 are symmetrically arranged on both sides of the guide rail 100 and connected to the support body 231. A limiting wheel 236 is provided at one end of the limiting rod 235 close to the guide rail 100, and the limiting wheel 236 is in rolling cooperation with the side wall of the guide rail 100. Specifically, the limiting rods 235 are horizontally arranged. One limiting rod 235 is located on the left side of the guide rail 100. One end of the left limiting rod 235 is connected to the left limiting plate 234 by a nut, and a limiting wheel 236 is provided at the right end of the left limiting rod 235. The left limiting wheel 236 is in rolling cooperation with the left side wall of the guide rail 100. The limiting rod 235 is horizontally arranged. The other limiting rod 235 is located on the right side of the guide rail 100. One end of the right limiting rod 235 is connected to the right limiting plate 234 by a nut, and a limiting wheel 236 is provided at the left end of the right limiting rod 235. The right limiting wheel 236 is in rolling cooperation with the right side wall of the guide rail 100. When the rolling support 230 moves along the guide rail 100, the rolling wheel 232 rolls along the length direction of the guide rail 100, thereby realizing the movement of the entire awning. When the rolling support 230 has a tendency to deviate from the guide rail 100, the limiting wheel 236 contacts the guide rail 100 to prevent the rolling support 230 from deviating from the guide rail 100, ensuring that the rolling support 230 can only move along the length direction of the guide rail 100.

[0048] In an embodiment of the present utility model, the movable movable formwork awning further includes a driving component 500 (not shown). The driving component 500 is connected to the guide rail 100 and at least one column 210, and the driving component 500 is used to drive the support component 200 to move. Specifically, the driving component 500 includes a fixed seat, a driving motor and a roller. The fixed seat is connected to the column 210 at the tail of the awning. The driving motor is arranged on the fixed seat. The roller is connected to the rotating shaft 233 of the driving motor, and the roller is in rolling cooperation with the guide rail 100. When the driving motor drives the roller to rotate, under the action of friction, the entire awning is driven to move along the length direction of the guide rail 100.

[0049] In an embodiment of the present utility model, the movable movable formwork awning further includes a position sensor. The position sensor is one of an electromagnetic position sensor, an optoelectronic position sensor or a Hall position sensor. The position sensor is arranged on one side of the guide rail 100, and the position sensor is electrically connected to the driving component 500. The position sensor is used to control the driving component 500 to stop working when it detects that the support component 200 reaches a predetermined position. Setting the position sensor can prevent the movement position of the awning from exceeding the predetermined position, avoiding collisions or safety accidents, and improving the safety of the awning.

[0050] In an embodiment of the present utility model, the movable mobile formwork awning further includes an alarm, which is electrically connected to the position sensor. When the position sensor detects that the support member 200 reaches a predetermined position, the position sensor outputs an alarm signal to the alarm, and the alarm reminds the staff to intervene in time to prevent dangerous situations from occurring.

[0051] In an embodiment of the present utility model, the movable mobile formwork awning further includes a control box 600, which is electrically connected to the drive motor, and the staff can perform manual control through the control box 600.
