Description

Technical Field

[0001] This utility model relates to the field of construction protection net technology, and in particular to a wet joint protection net. Background Technology

[0002] Highway and municipal engineering construction involves many bridge constructions. The bridge structure includes both cast-in-place and precast beams. After the precast beams are hoisted onto the bridge supports, the construction of transverse beams and wet joints begins. During the bridge deck paving construction, safety management requirements necessitate the implementation of safety protection measures. In particular, dense mesh netting and other relevant safety protection measures must be installed at wet joints, bridge medians, and bridge railings to prevent falls and injuries.

[0003] Generally, safety netting with a fine mesh is used in areas such as central dividers and wet joints, along with safety signs and markers, to prevent accidents. However, in actual on-site construction, the placement and storage of the safety netting present inconveniences. To solve the problems of retrieval and storage, rotating drums can be used to store the safety netting. However, the rotating drums currently used on-site have a fixed netting direction, making them difficult to adapt to complex and diverse on-site construction conditions. Especially when the reinforcing bars fixing the rotating drum are uneven, the safety netting will rub against the drum's groove during retrieval and storage, thus accelerating wear and tear and shortening its service life. Utility Model Content

[0004] This utility model provides a wet joint protection net to solve at least one of the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wet joint protection net, comprising:

[0007] A bracket, wherein a clip is provided on the lower side of the bracket;

[0008] A rotating drum has connectors at both ends, which are rotatably connected to the drum. The connectors are connected to the bracket. A roller is provided on the inner side of the rotating drum, and a protective net is wound around the roller. One end of the roller is connected to a wheel through a rotating shaft, which is rotatably connected to the connector. A slot adapted to the protective net is opened on the side wall of the rotating drum, and a hook is provided at one end of the protective net.

[0009] In one embodiment, the bracket is provided with a retainer, which is correspondingly arranged with the rotating drum.

[0010] In one embodiment, the retainer includes a screw, a screw seat, and a suction cup. The screw seat is fixedly connected to the bracket, and the screw and the screw seat are connected by a screw pair. The suction cup is disposed at one end of the screw and abuts against the rotating cylinder.

[0011] In one embodiment, a locking bolt is provided on the upper side of the connector, the locking bolt is correspondingly arranged with the rotating shaft, the locking bolt passes through the connector, and one end of the locking bolt abuts against the rotating shaft.

[0012] In one embodiment, a protrusion is provided on the outer side of the rotating shaft, a compression spring is provided on the lower side of the locking bolt, a positioning bead is provided on the lower side of the compression spring, and the positioning bead abuts against the groove formed between two adjacent protrusions.

[0013] In one embodiment, a protective sleeve is provided at the opening of the rotating drum, the width of the protective sleeve is adapted to the protective net, and the protective sleeve is made of a flexible material.

[0014] In one embodiment, the protective net is provided with reinforcing ribs along its pull-out direction, the reinforcing ribs are connected to the hooks, and adjacent reinforcing ribs are spaced 10 to 50 centimeters apart.

[0015] In one embodiment, the support is provided with a hanging rod parallel to the rotating drum for attaching hooks to adjacent wet joint protective nets.

[0016] In one embodiment, the hanging rod is provided with a groove corresponding to the hook, and the depth of the groove is 2 to 20 centimeters; or, the hanging rod is provided with a positioning hole corresponding to the hook.

[0017] In one embodiment, a secondary protective net is also wound around the roller, the secondary protective net overlapping and wrapped around the roller with the protective net, and the rotating drum is also provided with a secondary groove adapted to the secondary protective net.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model, by setting up a bracket and installing clips on the underside of the bracket and hooks on the protective net, makes it easy to fix the entire protective net in the construction position. Compared with the traditional method, the installation is more convenient and the efficiency of the protective net deployment is improved. At the same time, the use of a rotatable drum to store the protective net allows for flexible adjustment of the net's exit direction according to different on-site construction conditions. This solves the problem that the existing rotatable drum's fixed exit direction is difficult to adapt to complex construction scenarios, and also reduces the wear and tear on the protective net, extending its service life.

[0020] This invention uses a fixing device to fix the angle of the rotating drum, ensuring the stability of the device during use; and uses locking bolts to fix the rollers, thereby adjusting the length of the protective net and enhancing the adaptability of the device.

[0021] This invention, by setting a protective sleeve at the opening of the rotating drum, avoids direct friction between the protective net and the opening of the rotating drum during the netting process, further reducing wear on the protective net and extending its service life.

[0022] This utility model features a hanging rod parallel to the rotating drum on a support frame. After the protective net is pulled out, it can be hung on the hanging rod of an adjacent device via a hook. This is suitable for situations where the required length of the protective net is excessive. The hanging rod has a groove corresponding to the hook, which makes the protective net more stable and less prone to shaking during use.

[0023] This invention enhances the strength of the protective net by adding reinforcing ribs along the pulling direction, making it more durable and less prone to damage during use.

[0024] This invention provides a protective net in two directions by winding a secondary protective net around the roller and providing a matching secondary groove on the rotating drum, thus meeting the protection requirements of different construction scenarios. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] Reference Figure 1-5A wet joint protection net includes: a rotating cylinder 1 and a support 2; the rotating cylinder 1 has connectors 7 at both ends, and the rotating cylinder 1 and connectors 7 are rotatably connected. The connectors 7 are connected to the support 2. This arrangement allows the angle of the rotating cylinder 1 to be adjusted to adapt to protection in different directions and to suit complex construction scenarios. A roller is provided on the inner side of the rotating cylinder 1, and a protective net 3 is wound around the roller. One end of the roller is connected to a rotating wheel 6 via a rotating shaft 61, which is rotatably connected to the connectors 7. The side wall of the rotating cylinder 1 has a slot adapted to the protective net 3 for passage. One end of the protective net 3 has a hook 4. By rotating the rotating wheel 6 to drive the roller to rotate, the protective net 3 can be stored and retrieved. The hook 4 facilitates the fixing of the protective net 3. Two sets of supports 2 are respectively set at both ends of the rotating cylinder 1 for fixing and supporting the rotating cylinder 1 and for installation at the construction site. The lower side of the support 2 has clips 5 for easy fixing to the steel bars of the bridge.

[0037] The bracket 2 is also equipped with a fixator 10, which is correspondingly set with the rotating drum 1 to fix the rotation angle of the rotating drum 1, ensure the stability of the device during use, and reduce the wear of the protective net 3.

[0038] Specifically, the retainer 10 includes a screw, a screw seat, and a suction cup. The screw seat is fixedly connected to the bracket 2, and the screw and screw seat are connected by a screw pair. The suction cup is located at one end of the screw and abuts against the rotating cylinder 1. In use, the screw can be unscrewed a certain distance to move the suction cup away from the rotating cylinder 1. Then, the rotating cylinder 1 can be rotated to a suitable angle, and the screw can be screwed back to make the suction cup abut against the rotating cylinder 1, thus fixing the rotating cylinder 1.

[0039] In another embodiment, the fixture 10 includes a fixing pin and a spring seat. The rotating cylinder 1 has several positioning holes on its side. The spring seat is fixedly connected to the bracket 2. The fixing pin is inserted into the spring seat. Under the pressure of the spring seat, the fixing pin is inserted into the positioning hole on the side of the rotating cylinder 1. Before rotating the rotating cylinder 1, the fixing pin is pulled out. After rotating the rotating cylinder 1, when the positioning hole at the new angle is turned to the fixing pin, the fixing pin is released. Under the pressure of the spring, the fixing pin is inserted into the positioning hole to fix the rotating cylinder 1.

[0040] When the entire length of the protective net 3 is not needed, and only a portion of the protective net 3 is used, the roller needs to be fixed after a certain length of netting has been extended. In this embodiment, the roller's shaft 61 is fixed by setting a locking bolt 71. A locking bolt 71 is provided on the upper side of the connector 7. The locking bolt 71 is correspondingly set with the shaft 61. The locking bolt 71 passes through the connector 7, and one end of the locking bolt 71 abuts against the shaft 61.

[0041] Specifically, a protrusion 62 is provided on the outer side of the rotating shaft 61, a compression spring 72 is provided on the lower side of the locking bolt 71, and a positioning bead 73 is provided on the lower side of the compression spring 72. The positioning bead 73 abuts against the groove formed between two adjacent protrusions 62. When a complete lock-on is required, simply tighten the locking bolt 71. This arrangement can further enhance the fixing effect of the locking bolt 71 on the rotating shaft 61 and prevent the protective net 3 from loosening.

[0042] A protective sleeve 11 is provided at the opening of the rotating drum 1. The width of the protective sleeve 11 is adapted to the protective net 3. The protective sleeve 11 is made of a flexible material, such as rubber. This avoids direct friction between the protective net 3 and the opening of the rotating drum 1 during the netting process, further reducing the wear of the protective net 3, extending the service life of the protective net 3, and preventing the protective net 3 from being scratched or damaged by the opening.

[0043] To further enhance the strength of the protective net 3, reinforcing ribs 31 can be installed along the pulling direction of the protective net 3. The reinforcing ribs 31 are connected to the hooks 4. The width of the wet joint of the bridge is usually between 50 and 95 cm. Therefore, reinforcing ribs 31 can be installed at intervals of 10 to 50 cm to improve the tensile strength of the protective net 3.

[0044] When protecting a long distance of wet joint, a hanging rod 9 parallel to the rotating drum 1 can be installed on the bracket 2 for attaching hooks 4 of adjacent wet joint protection nets. After the protection net 3 is pulled out, it can be hung on the hanging rod 9 of the adjacent device through the hooks 4. The hanging rod 9 has grooves corresponding to the hooks 4, with a depth of 2-20 cm; or, the hanging rod 9 has positioning holes corresponding to the hooks 4. When installing the protection net 3, the hooks 4 of the protection net 3 are attached to the grooves of the hanging rod 9 of the adjacent wet joint protection net, or threaded through the positioning holes of the hanging rod 9, which makes the protection net 3 more stable and less prone to shaking during use.

[0045] In addition, a single protective net 3 can be replaced with a double-layer net, with a protective net 3 and a secondary protective net 8 set up, both overlapping and wrapped around the roller. The rotating drum 1 is provided with a secondary groove that matches the secondary protective net 8. When in use, the protective net 3 and the secondary protective net 8 are pulled out at the same time, which is suitable for wet joint protection over a longer distance. The bracket 2 is set in the middle, which can better fix the wet joint protective net, prevent the protective net 3 and the secondary protective net 8 from becoming loose, and improve the reliability of protection. At the same time, reinforcing ribs 31 can be woven into the protective net 3 and the secondary protective net 8 to improve the overall strength and make it easier to straighten the protective net 3 and the secondary protective net 8.

[0046] The method of using this utility model is as follows:

[0047] When construction of the crossbeams and wet joints begins, protective nets are installed at the wet joints, bridge median strips, and bridge railings. The bracket 2 is fixed with clips 5. The locking bolts 71 and the fixing device 10 are loosened to allow the rollers and rotating drum 1 to move freely. The protective net 3 is pulled to cover the areas that need protection. The pull-out end of the protective net 3 is fixed with hooks 4. The locking bolts 71 and screws are tightened to fix the rollers and rotating drum 1.

[0048] After construction is completed, clean the protective net 3, remove the hook 4, loosen the locking bolt 71, rotate the rotating wheel 6, and roll the protective net 3 onto the roller. The rotating drum 1 protects the protective net 3 from aging and damage caused by wind and sun.

[0049] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
