Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a bridge construction auxiliary device. Background Art

[0002] Bridges generally refer to structures erected on rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected across mountain streams, poor geology, or to meet other transportation needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports, and auxiliary structures. The superstructure is also called the bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the support is a force transmission device installed at the supporting location of the bridge span structure and the piers or abutments; the auxiliary structures refer to the bridgehead slab, conical slope protection, revetment, diversion projects, etc. When building a bridge, it is necessary to install guardrails on the abutments. However, since the abutments are close to both sides of the bridge body, construction tools or gravel may fall during the installation of the guardrails, threatening the personal safety of people under the bridge deck.

[0003] According to the public patent 202021739159.2, an auxiliary construction device for bridge construction includes a bridge deck, wherein the left side of the top of the bridge deck is fixedly connected to a bridge abutment, and the top of the bridge deck is movably connected to a storage plate located on the right side of the abutment, and two first movable wheels are fixedly connected to the left and right sides of the bottom of the storage plate, and two first electric slides are fixedly connected to the left side of the top of the storage plate, and a movable plate is fixedly connected between the sliders of the two first electric slides, and an adjusting screw that penetrates the movable plate and extends to the left side of the movable plate is threadedly connected on the right side of the movable plate. The auxiliary construction device for bridge construction solves the problem that guardrails need to be installed on abutments during bridge construction. However, since the abutments are relatively close to both sides of the bridge body, construction tools or gravel may fall during the installation of the guardrails, threatening the personal safety of people under the bridge deck. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the installation site can be protected by the first and second protective nets to prevent construction tools or gravel from falling, thereby achieving the purpose of improving construction safety, thus effectively solving the problem that guardrails need to be installed on abutments during bridge construction, since the abutments are relatively close to both sides of the bridge body During the installation of the guardrail, construction tools or gravel may fall, threatening the personal safety of people under the bridge deck. However, during use, the traditional bridge construction auxiliary device, the interception net, needs to move horizontally and vertically, which limits the size of the interception net and cannot be set larger. As a result, it can only block gravel and falling objects in a small range, and the interception effect is not very good. Moreover, during use, the device can only intercept the bottom of one side of the bridge deck, and cannot intercept the bottom of both sides of the bridge deck. As a result, two devices need to be set up to intercept the two sides of the bottom of the bridge deck respectively, which is not very convenient. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a bridge construction auxiliary device to solve the current traditional bridge construction auxiliary device. Since the interception net needs to move horizontally and vertically, the size of the interception net is limited, and the interception net cannot be set larger, resulting in that it can only block gravel and dropped objects in a small range, and the interception effect is not very good. Moreover, during use, the device can only intercept the bottom of one side of the bridge deck, and cannot intercept the bottom of both sides of the bridge deck, resulting in the need to set up two devices to intercept the two sides of the bottom of the bridge deck respectively, which is not a very convenient technical problem.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a bridge construction auxiliary device, including a device box, the top of the device box is an open structure, and also includes:

The utility model, through the combination of an L-shaped plate, an electric telescopic cylinder and a driving motor, can not only utilize the electric telescopic cylinder to drive the protection frame plate and the protection net to move up and down and move the protection net to the side of the bridge deck, but also can drive the protection frame plate and the protection net to rotate and move through the driving motor, and screw the protection frame plate and the protection net to the bottom of the bridge deck. By rotating the protection frame plate and the protection net to the bottom of the bridge deck, the protection frame plate and the protection net can be set to a larger size, eliminating the need for long-distance lateral movement of the protection frame plate and the protection net, and solving the technical problem of traditional bridge construction auxiliary devices, that the size of the interception net is limited due to the need for lateral and vertical movement, and the interception net cannot be set larger, resulting in only being able to block gravel and dropped objects in a small range, and the interception effect is not very good.

[0016] 2. The utility model, through the combination of a dual-axis motor, a threaded rod and an L-shaped plate, can utilize the dual-axis motor to simultaneously drive the two threaded rods to rotate, and drive the two L-shaped plates to move simultaneously through the two rotating rods, thereby simultaneously adjusting the distance between the two L-shaped plates and the protective frame plates, so that it can be applied to bridge decks of different widths, and can simultaneously perform protective interception on the bottom of both sides of the bridge deck, thereby solving the problem that during use, the device can only intercept the bottom of one side of the bridge deck, but cannot intercept the bottom of both sides of the bridge deck, resulting in the need to set up two devices to intercept the two sides of the bottom of the bridge deck respectively, which is not a very convenient technical problem.
