A movable sunshade canopy for prefabricated beam yard

Abstract

The present invention discloses a movable sunshade awning for a prefabricated beam yard, which belongs to the technical field of prefabricated construction of beam yards. A rotating handle is arranged to drive a first bevel gear to rotate, and the first bevel gear drives a screw rod to rotate through a second bevel gear. During the rotation of the screw rod, a nut will move upward, so that the nut can pull connecting rods on both sides to deflect at an angle. The two connecting rods pull two upright posts closer to each other, so that the secondary pulleys at the bottom of the upright posts roll on the ground. Since the top ends of the upright posts are hinged to the scaffolding, the scaffolding can be driven to deflect at an angle during the movement of the upright posts, so that the two scaffoldings can drive the supporting main beam to move upward, so that the supporting main beam can slide in a slideway on the door frame, and the supporting main beam can be kept to move vertically upward. Since the secondary pulley is close to the main pulley, the entire sunshade awning is narrowed, and thus the shading area can be adjusted. This can be suitable for operation requirements in different scenes, and at the same time, it brings convenience to the transportation of the sunshade awning.

Description

Technical Field

[0001] The invention belongs to the technical field of beam field prefabrication construction, and in particular relates to a movable sunshade canopy for a prefabricated beam field. Background Art

[0002] The steel pedestal in the precast beam yard is a structure that is prefabricated in order to speed up the construction efficiency of the beam. During the prefabrication process, in order to ensure the quality of production and processing, the processed steel pedestal in the precast beam yard needs to be ventilated and maintained, so a sunshade and rainproof awning is needed.

[0003] Although the sunshade awnings in the prior art can be moved when in use, which makes it easy to transfer the sunshade awnings, the sunshade awnings are usually of one-piece design, which is extremely inconvenient to replace the entire awning board. At the same time, the roof needs to be welded and filled when it is damaged, which affects the appearance and increases the difficulty of work. Due to the large size of the one-piece design of the sunshade awning, it is difficult to meet the operational needs in different scenarios, and it also brings difficulties to the overall transportation work. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the present invention provides a movable sunshade awning for a prefabricated beam yard, which solves the problem that the sunshade awning is usually an integrated design, which is extremely inconvenient to replace the entire shed board, and the roof needs to be welded and filled when it is damaged, which affects the appearance and increases the difficulty of work; since the sunshade awning with an integrated design is large in size, it is difficult to adapt to the operational needs in different scenarios, and it also brings difficulties to the overall transportation work.

Since the secondary pulley is close to the main pulley, the entire sunshade canopy is narrowed, so that the sunshade area can be adjusted, which can be applied to the operation requirements in different scenes and bring convenience to the transportation of the sunshade canopy.

[0007] The modular design of the shielding panels makes it easier to maintain the awning, abandoning the traditional method of using one-piece awning panels and reducing the difficulty of the work.

[0009] The external thread of the screw rod is connected to a nut, and connecting rods are hinged on both sides of the nut through pins. Sliding holes are opened on both sides of the baffle frame, and the connecting rods are slidably connected in the sliding holes. Columns are hinged on both sides of the bottom of the scaffolding through pins, and the bottom end of the column is fixedly connected to an auxiliary pulley, and a main pulley is provided between the two opposite auxiliary pulleys, and the main pulley is fixedly connected to the bottom of the door frame.

[0010] As a further solution of the present invention: a slideway is provided on the top of the door frame, and the bottom end of the supporting main beam is slidably connected in the slideway.

[0011] As a further solution of the present invention: the shielding assembly includes a limiting plate, the limiting plate is clamped in the mounting hole, a shielding plate is provided on the limiting plate, and one side of the shielding plate is inclined.

[0012] As a further solution of the present invention: six clamping holes are opened in the mounting hole, and limiting columns are arranged through the clamping holes. The top ends of the six limiting columns are fixed to the bottom of the shielding plate, and a drainage groove is provided between two adjacent mounting holes. The drainage groove is opened on the scaffolding, and one side of the shielding plate is embedded in the drainage groove.

[0013] As a further solution of the present invention: the adjustment assembly includes a first bevel gear, the first bevel gear is meshed with a second bevel gear, the second bevel gear is clamped outside the screw rod, a rotating handle is fixed on the front side of the first bevel gear, and the rotating handle is arranged on the baffle frame.

[0014] As a further solution of the present invention: the bottom end of the sliding rod is fixed to the door frame, the top end of the sliding rod is fixed to the top of the baffle frame, the sliding rod outer shell is connected with a sliding sleeve, the two sides of the sliding sleeve are respectively hinged with support rods through pins, and the support rods are slidably connected in the sliding hole.

[0015] As a further solution of the present invention: the two upright posts at the bottom of the scaffold are respectively hinged to one end of a connecting rod and a supporting rod through a pin, and the connecting rod and the supporting rod are both designed to be tilted upward.

[0016] As a further solution of the present invention: the supporting main beam is designed to be U-shaped, and the top of the supporting main beam is designed to be an arc surface, and a triangular reinforcement plate is provided between the supporting main beam and the baffle frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The second gear wheel is close to the main gear wheel, and the second gear wheel drives the screw rod to rotate, and the nut moves upward during the rotation of the screw rod, so that the nut can pull the connecting rods on both sides to deflect at an angle, so that the bottom ends of the two connecting rods are close to each other. Since the bottom ends of the connecting rods are hinged with the upright posts at the bottom of the scaffolding, the two connecting rods pull the two upright posts close to each other, so that the secondary pulleys at the bottom of the upright posts roll on the ground. Since the top ends of the upright posts are hinged with the scaffolding, the scaffolding can be driven to deflect at an angle during the movement of the upright posts, so that the two scaffolding can drive the supporting main beams to move upward, so that the supporting main beams can slide in the slideway on the door frame, and keep the supporting main beams moving vertically upward. Since the secondary pulley is close to the main pulley, the entire sunshade canopy is narrowed, and thus the sunshade area can be adjusted, which can be suitable for operation needs in different scenes and brings convenience to the transportation of the sunshade canopy.

[0019] 2. In the present invention, the limiting plate and the shielding plate are set up by setting the mounting holes. When installing the shielding plate, the six limiting columns at the bottom of the limiting plate are inserted into the holes to limit the shielding plate and prevent the shielding plate from shifting to affect the waterproof effect. One side of the two adjacent shielding plates is embedded in the drainage groove, so that rainwater falling between the two shielding plates can be discharged along the drainage groove to prevent water from seeping under the supporting main beam, thereby further improving the waterproof effect of the sunshade. When replacing the shielding plate, the shielding plate is tilted to make the limiting plate detach from the mounting hole, and the single shielding plate can be removed and embedded in the mounting hole after maintenance or replacement. Therefore, the shielding plate with modular design is more convenient for the maintenance of the sunshade, abandoning the traditional method of using an integrated shed plate and reducing the difficulty of work.

[0020] 3. In the present invention, the main pulley arranged at the bottom of the door frame and the auxiliary pulley arranged at the bottom of the column can not only play a role in providing stable support for the sunshade awning, but also facilitate the transfer of the sunshade awning, thereby greatly improving the wide application of the sunshade awning. Since there are sliding sleeves and sliding rods in one of the retaining frames, the sliding sleeve can slide freely outside the sliding rod, and cooperate with the support rod hinged outside the sliding sleeve to support the column, so that the supporting main beam will not slide when moving and will be more stable.

[0030] See also Figure 1-7 , the present invention provides a technical solution for a movable sunshade awning in a prefabricated beam yard:

[0031] Embodiment 1:

[0032] according to Figure 1 , Figure 3 and Figure 5 , Figure 6As shown, a movable sunshade canopy in a prefabricated beam yard includes a door frame 1, the number of the door frames 1 is two, the two door frames 1 are provided with supporting main beams 2, the two sides of the supporting main beams 2 are respectively hinged with scaffolds 4 through pin shafts, the scaffolds 4 are provided with four mounting holes 5, and shielding components 6 are installed in the mounting holes 5. The two door frames 1 are respectively fixed with blocking frames 9 on the sides away from each other, one of the blocking frames 9 is provided with an adjusting component 10, and the other blocking frame 9 is provided with a sliding rod 15, and the adjusting component 10 is externally clamped with a screw rod 11. The adjustment assembly 10 includes a first bevel gear 101, a second bevel gear 102 is meshed on the first bevel gear 101, and the second bevel gear 102 is clamped outside the screw rod 11. A handle 103 is fixed to the front of the first bevel gear 101, and the handle 103 is arranged on the stop frame 9. Through the mutual cooperation between the first bevel gear 101 and the second bevel gear 102, the screw rod 11 can be rotated by the handle 103, which is convenient for adjusting the position of the nut 12 and the connecting rod 13, thereby improving the convenience of operation.

[0033] The two ends of the screw rod 11 are connected to the top of the retaining frame 9 and the door frame 1 through bearings respectively;

[0034] The screw rod 11 is externally threaded with a nut 12, and connecting rods 13 are respectively hinged on both sides of the nut 12 through pins. Slide holes 14 are opened on both sides of the baffle frame 9, and the connecting rods 13 are slidably connected in the slide holes 14. The two sides of the bottom of the scaffolding 4 are respectively hinged with columns 17 through pins. During the movement of the columns 17, the scaffolding 4 can be driven to deflect at an angle, so that the two scaffoldings 4 drive the supporting main beam 2 to move upward, so that the supporting main beam 2 can slide in the slideway 3 on the door frame 1, and keep the supporting main beam 2 moving vertically upward. Since the secondary pulley 18 is close to the main pulley 19, the entire sunshade canopy is narrowed, and the sunshade area can be adjusted, which can be suitable for operation requirements in different scenes;

[0035] A secondary pulley 18 is fixedly connected to the bottom end of the column 17, and a main pulley 19 is provided between the two opposite secondary pulleys 18. The main pulley 19 is fixedly connected to the bottom of the door frame 1. The main pulley 19 arranged at the bottom of the door frame 1 and the secondary pulley 18 arranged at the bottom of the column 17 can provide stable support for the sunshade awning and facilitate the transfer of the sunshade awning, thereby greatly improving the wide application of the sunshade awning.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, Figure 1-4 and Figure 6 , Figure 7 As shown, a slideway 3 is provided on the top of the gantry 1, and the bottom end of the supporting main beam 2 is slidably connected in the slideway 3. Because of the provision of the slideway 3, the slideway 3 serves to limit the supporting main beam 2, thereby ensuring the stability of the vertical movement of the supporting main beam 2.

[0038] The shielding assembly 6 includes a limiting plate 601, which is clamped in the mounting hole 5. A shielding plate 602 is provided on the limiting plate 601, and one side of the shielding plate 602 is inclined.

[0039] Six clamping holes 7 are provided in the mounting hole 5, and the six limiting posts 603 at the bottom of the limiting plate 601 are clamped into the clamping holes 7 to limit the shielding plate 602, thereby preventing the shielding plate 602 from shifting and affecting the waterproof effect;

[0040] A limiting column 603 is arranged through the card hole 7, and the top ends of the six limiting columns 603 are fixed to the bottom of the shielding plate 602. A drainage groove 8 is provided between two adjacent mounting holes 5. The drainage groove 8 is opened on the shed 4, and one side of the shielding plate 602 is embedded in the drainage groove 8. One side of two adjacent shielding plates 602 is embedded in the drainage groove 8, so that rainwater falling between the two shielding plates 602 can be discharged along the drainage groove 8, preventing water from seeping into the bottom of the supporting main beam 2, thereby further improving the waterproof effect of the sunshade awning.

[0041] The bottom end of the slide rod 15 is fixed to the door frame 1, and the top end of the slide rod 15 is fixed to the top inside the baffle frame 9. A slide sleeve 16 is connected to the outer surface of the slide rod 15. Support rods 20 are hinged on both sides of the slide sleeve 16 through pins. The support rods 20 are slidably connected in the slide hole 14. A slide sleeve 16 and a slide rod 15 are provided in one of the baffle frames 9. The slide sleeve 16 can slide freely outside the slide rod 15, and the support rod 20 hingedly arranged outside the slide sleeve 16 supports the column 17, so that the supporting main beam 2 will not slide during movement and is more stable.

[0042] The two columns 17 at the bottom of the scaffolding 4 are hinged to one end of the connecting rod 13 and the support rod 20 through a pin shaft respectively. The connecting rod 13 and the support rod 20 are both designed to be inclined upward. The supporting main beam 2 is designed to be U-shaped, and the top of the supporting main beam 2 is designed to be an arc surface. A triangular reinforcement plate is provided between the supporting main beam 2 and the retaining frame 9.

[0043] Working principle:

[0044] When replacing the shielding plate 602, the shielding plate 602 is tilted to make the limiting plate 601 disengage from the mounting hole 5, and the single shielding plate 602 can be removed. The mounting hole 5 is set to erect the limiting plate 601 and the shielding plate 602. When installing the shielding plate 602, the six limiting columns 603 at the bottom of the limiting plate 601 are snapped into the snap holes 7 to limit the shielding plate 602, and one side of the two adjacent shielding plates 602 is embedded in the drainage groove 8, so that rainwater falling between the two shielding plates 602 can be discharged along the drainage groove 8. When adjusting the sunshade awning, the first bevel gear 101 is driven to rotate by the turning handle 103, and the first bevel gear 101 drives the screw rod 11 to rotate through the second bevel gear 102. During the rotation of the screw rod 11, the screw The nut 12 will move upward, so that the nut 12 can pull the connecting rods 13 on both sides to deflect at an angle, so that the bottom ends of the two connecting rods 13 are close to each other. Since the bottom ends of the connecting rods 13 are hinged to the columns 17 at the bottom of the scaffolding 4, the two connecting rods 13 pull the two columns 17 close to each other, so that the secondary pulley 18 at the bottom of the columns 17 rolls on the ground. Since the top ends of the columns 17 are hinged to the scaffolding 4, the scaffolding 4 can be driven to deflect at an angle during the movement of the columns 17, so that the two scaffoldings 4 drive the supporting main beams 2 to move upward, so that the supporting main beams 2 can slide in the slideways 3 on the door frames 1, and keep the supporting main beams 2 moving vertically upward. Since the secondary pulley 18 is close to the main pulley 19, the entire sunshade canopy is narrowed, and the shading area can be adjusted.

[0045] From the above we know:

[0046] The first bevel gear 101 is driven to rotate by setting a rotating handle 103, and the first bevel gear 101 drives the screw rod 11 to rotate through the second bevel gear 102. During the rotation of the screw rod 11, the nut 12 moves upward, so that the nut 12 can pull the connecting rods 13 on both sides to deflect at an angle, so that the bottom ends of the two connecting rods 13 are close to each other. Since the bottom ends of the connecting rods 13 are hinged to the columns 17 at the bottom of the scaffold 4, the two connecting rods 13 pull the two columns 17 close to each other, so that the secondary pulley 18 at the bottom of the column 17 is on the ground. Rolling, since the top of the column 17 is hinged with the scaffolding 4, the column 17 can drive the scaffolding 4 to deflect at an angle during its movement, so that the two scaffoldings 4 drive the supporting main beam 2 to move upward, and the supporting main beam 2 can slide in the slide 3 on the door frame 1, keeping the supporting main beam 2 moving vertically upward. Since the secondary pulley 18 is close to the main pulley 19, the entire sunshade canopy is narrowed, and the shading area can be adjusted. It can be suitable for operating needs in different scenarios, and at the same time brings convenience to the transportation of the sunshade canopy.

[0047] The limiting plate 601 and the shielding plate 602 are set up by setting the mounting hole 5. When installing the shielding plate 602, the six limiting columns 603 at the bottom of the limiting plate 601 are inserted into the locking hole 7 to limit the shielding plate 602 and prevent the shielding plate 602 from shifting to affect the waterproof effect. One side of the two adjacent shielding plates 602 is embedded in the drainage groove 8, so that rainwater falling between the two shielding plates 602 can be discharged along the drainage groove 8 to prevent water from seeping under the supporting main beam 2, thereby further improving the waterproof effect of the sunshade. When replacing the shielding plate 602, the shielding plate 602 is tilted to make the limiting plate 601 detach from the mounting hole 5, and the single shielding plate 602 can be removed and embedded in the mounting hole 5 after maintenance or replacement. Therefore, the modularly designed shielding plate 602 is more convenient for the maintenance of the sunshade, abandoning the traditional method of using an integrated shed plate and reducing the difficulty of work.

[0048] By means of the main pulley 19 arranged at the bottom of the door frame 1 and the auxiliary pulley 18 arranged at the bottom of the column 17, the sunshade can be stably supported and the sunshade can be easily transferred, which greatly improves the wide application of the sunshade. Since there are sliding sleeves 16 and sliding rods 15 in one of the retaining frames 9, the sliding sleeve 16 can slide freely outside the sliding rod 15, and the support rod 20 hingedly arranged outside the sliding sleeve 16 can support the column 17, so that the supporting main beam 2 will not slide when moving and is more stable.
